DETAILED DESCRIPTION
[0036]
[0037] The apparatus 10 as disclosed herein, as illustrated at
[0038] While the apparatus 10 as disclosed herein may be utilized as an effective wave break and be functional with only first and second wall members 18, 40, a preferred embodiment employs a third longitudinally extending wall member 60 spaced apart from and parallel to the second longitudinally extending wall member 40. The third wall member 60 is preferably spaced apart from the second wall member 40 by about 25 inches; however, as previously noted, this preferred span can vary by up to 10 inches.
[0039] The third longitudinally extending wall member 60, as illustrated at
[0040] The wall members 18, 40, 60 are preferably fabricated from medium grade raw steel with a standard gauge in the range of 10-12 (0.1046 to 0.1345 inches). The reference to medium grade raw steel should not; however, be considered as limiting for this disclosure as other materials such as engineered polymers, aluminum, stainless steel, and composites are also contemplated by this disclosure. The through holes 34, 54, 74 in each wall member 18, 40, 60 have a diameter that is preferably in the range of about 6-10 inches and more preferably about 7-9 inches.
[0041] CFD modeling of the wave break apparatus 10 has demonstrated that the diameter of the openings 34, 54, 74 impacts the level of force applied to the apparatus from the advancing wave of water and specifically the magnitude of force applied to the wall members 18, 40, 60. Wave action forces repeatedly acting upon the wave break apparatus 10 can result in damage to the apparatus 10 and can potentially dislodge the wave break apparatus anchorage 126 causing undesirable repositioning of the apparatus 10 in the wake zone. The energy extracted from the advancing wave action is effectively diminished as the water impacts each wall member and passes through the openings 34, 54, 74 in each of the wall members 18, 40, 60.
[0042] Consequently, CFD modeling is beneficial in that it has been used to optimize the physical structure of the wave break apparatus 10 in order to maximize the reduction in wave velocity and yet to minimize the wave action forces applied to the wall members 18, 40, 60. Table 1 below illustrates the output of the CFD modeling performed on a wave break apparatus 10 as disclosed herein utilizing an advancing wave speed of 60 inches per second or about 3.4 miles per hour.
[0043] As can also be seen from the CFD modeling data in Table 1, the load on the wall members 18, 40, 60 decreases when the opening diameter increases from 5 to 7 inches as well as when the opening diameter decreases from 5 to 3 inches, with the total number of holes in each wall member remaining constant. CFD modeling further reveals that the speed of water advancing beyond the wave break apparatus 10 drops most precipitously when the diameter of the openings 34, 54, 74 is about 7-8 inches.
[0044] Graphical representation of the movement of water as best illustrated at
[0045] With passage of the wave action through the openings 35 in the first wall member 18, wave velocity is decreased as illustrated by
TABLE-US-00001 TABLE 1 7-inch hole 5-inch hole 3-inch hole diameter diameter diameter Force on wall 2,372 3,937 4,946 member 18 (lbs) Force on wall 2,431 1,554 1,007 member 40 (lbs) Force on wall 774 462 77 member 60 (lbs) Total Force 5,577 5,953 5,876
[0046] The first wall member 18 utilizes about eight rows of through holes between the lower edge 26 and the upper edge 24. The second and third wall members 40, 60 employ a fewer number of through holes 54, 74 with the second wall member having a greater number of through holes than the third wall member. All three wall members 18, 40, 60 preferably have a vertical span of about 60 inches though taller or shorter wall members are contemplated by this disclosure. Each successive wall member after the first wall member 18 has progressively fewer through holes 54, 74 therein.
[0047] As illustrated at
[0048] A preferred embodiment of the apparatus requires the bracing members 80, 82, 84 to interrupt the span of all three wall members 18, 40, 60. In a preferred embodiment the mid-span bracing member 82 is welded to the internal end edges 90, 92 of all three wall members 18, 40, 60 as best illustrated at
[0049]
[0050] An exemplary restraining rope 124 is AmSteel II manufactured by Samson. The AmSteel II rope is highly durable and has a specific gravity greater than 1.0 so it does not float in water and should slack develop in the rope during use there is a diminished likelihood of the rope becoming entangled in the prop of a passing watercraft. The use of other ropes, including wire ropes and natural fiber ropes are also contemplated by this disclosure.
[0051]
[0052] The components of the first and second end members 110, 130 are preferably fabricated from medium grade steel of the same gauge as previously referenced. As illustrated at
[0053] These partial caps 146 stiffen the end members 110, 130 and provide a landing space for hardware, to be more fully detailed below, and include an opening 149 through which the restraining ropes 124 may pass downward to the diagonal brace member 120, 140 before the restraining rope exits out of the apparatus 10 to the anchors 126 at the floor 128 of the body of water 14.
[0054]
[0055] As best illustrated at
[0056]
[0057] As best illustrated at
[0058] The four winches 180 of the preferred embodiment of the apparatus 10 are each positioned atop a separate restraining member 166 and partial cap 146. The drum 188 of the winch 180 upon which the restraining rope 124 is wrapped may be manually adjusted with the crank arm 185 to regulate the tension on the rope 124.
[0059] In preparation for placement of the apparatus 10 into the body of water 14, the restraining members 166 are preferably removed so that four flotation members 150 of the preferred embodiment may be secured with fasteners 164, as best illustrated at
[0060]
[0061] As best illustrated at
[0062] As a wave advances toward the apparatus 10 it initially impacts the first wall member 18. Advancing water moves through the holes 34 or is obstructed by the area adjacent the holes. For the water that advances through the holes 34 it next advances past the gap 168 and impacts the first side surface 156 of the flotation member 150. Because of the solid nature of the flotation member 150 the advancing water is forced downward into the gap 168 and finally encounters a lack of obstruction at the lower surface 158 of the flotation member 150.
[0063] By the time the advancing water has moved to the lower surface 158 of the flotation member 150 it has lost a considerable portion of the energy that it initially had upon impact with the apparatus 10 due to friction losses resulting from interaction with the wall member 18 and the first side surface 156 of the flotation member 150. Once the water has advanced to the lower surface 158 of the flotation member 150 it can finally move forward (in the direction of the wave action) where it next encounters the second wall member 40 of the flotation member 150. As indicated above, the second wall member 40 has fewer through holes 54 than the first wall member 18.
[0064] The second wall member 40 being less porous (fewer through holes) than the first wall member resists passage of the water thereby extracting even more energy from the advancing wave of water. After passing through the openings 54 in the second wall member 40 the water advances across the next chamber beneath the flotation members 150 and encounters the third wall member 60.
[0065] The third wall member 60 has even fewer holes 74 than the second wall member 40 and water attempting to escape through the holes 74 will be placing pressure on the third wall member 60 further diminishing the energy carried by the advancing water. Numerical modeling using Computational Fluid Dynamics (CFD) reveals that a substantial portion of the energy initially carried by the wave action is lost upon contact with the apparatus 10 thereby reducing the potential for wave action causing damage to the shoreline, docks, or other floating structures.
[0066] The apparatus 10 as disclosed herein is also highly modular in nature and connectable to address protection of long shorelines or extended docks. As illustrated at
[0067] Another highly useful feature of the apparatus 10 as disclosed herein is the use of light towers 210 as illustrated at
