BLOWER SYSTEM FOR BLOWING FLUID OFF OF A PASSING VEHICLE

Abstract

Described is a blower system. The blower system includes one or more blowers. Each blower has an intake for providing air into an air chamber which houses an impeller. A gate covers each intake. Each gate is movable between a closed position in which it is pulled against the intake and an open position in which the gate is lifted off of the intake. A controller system is included that is operable for causing the gates to move from the closed to the open position when a vehicle is present or approaching and cause the gates to return to the closed position when no vehicle is present or leaving.

(1) Description

[0019] The present invention relates to a blower system and, more specifically, a blower system for blowing fluid off of a passing vehicle. The present invention includes all of the necessary hardware, sensors, software, and/or processors as may be needed to perform the feature as described and illustrated in this disclosure. As shown in FIG. 1, the blower system includes a frame system 100 having at least one and, desirably, a plurality of blowers 102 that are positioned about the frame system 100 to blow air onto a passing vehicle. Although the frame system can be used, it should be understood that the invention is not intended to be limited thereto as the blowers 102 can be hung or otherwise attached to a building or other component to position the blowers at the desired location such that they are operable for blowing air onto a passing vehicle.

[0020] Notably, as shown in FIG. 2, the blowers 102 include an actuatable gate 200 that is positioned over the intake 202 to the impeller chamber 204 of the blower. The gate 200 is an openable/closeable gate that is operated using any suitable mechanism or device, such as being pneumatically operated, solenoid operated, etc. The gate 200 is operable for selectively opening and closing the inflow of air into the impeller chamber 204, reducing the power required to operate the blower 102. When no vehicle is in service, an actuator 206 (e.g., pneumatically operated solenoid or cylinder, etc.) pulls the gate 200 over the intake 202 to the impeller chamber 204 to seal the intake 202 and close the gate 200 while allowing the motor to continue running.

[0021] Alternatively and as shown in FIG. 3, the actuators 206 can be actuated to lift the gate 200 off of the intake 202 to the impeller, chamber 204 to allow air to freely flow into the impeller chamber 204 and blower in an open position. It should be noted that the blower described herein is any suitable blower device that is operable for blowing water or fluid off of a passing vehicle, with the actuators 206, gate 200 and intake 202 being formed and/or otherwise operable to allow for selective operation of the gate 200. The gate 200 is attachable to most blowers commonly used in the industry and can be easily installed to retrofit most blowers. As stated above, the blower system described herein reduces power consumption on idle by half, as seen in FIG. 4, and works with any suitable compressor components, such as a small compressor (e.g., eight gates requires 0.256 CFM). The blower system is also made of a sufficient durable material (e.g. structural aluminum) that is able to withstand the necessary loads and strains of the system.

[0022] Due to the decreased air inflow, the motor load is dramatically increased when the gates are closed, by as much as 50%. This would allow the operator to leave the blowers on for longer periods in between vehicle washes, thereby eliminating the high current draw needed to restart blowers in between starts. FIG. 4, for example, provides a chart 400 illustrating the current usage comparison between a blower with no gate 402, a blower with an open gate 404, and a blower with a closed gate 406. As shown, the current needed to start up a blower with a closed gate 406 is much less (i.e., 9.7 amps) than a blower with no gate 402 (i.e., 20.1 amps) or a blower with an already opened gate 404 (i.e., 19.8 amps).

[0023] Alternatively, when a vehicle is present or approaching the blower station, the system (software, processors, etc.) causes the actuator 206 to lift the gates 200 off of the intake 202 to the impeller chamber 204, thereby allowing the blowers 102 to provide a full blow load. Thus, the system also includes a controller system having all of the necessary software, sensors, hardware, etc. to cause the gates to move from the closed to the open position when a vehicle is present (actually present or approaching, as desired and/or predetermined) and cause the gates to return to the closed position when no vehicle is present (actually not present or leaving, as desired and/or predetermined). As a non-limiting example and as shown in FIG. 1, the controller system 110 includes sensors 112 (e.g., infrared sensors, etc.) positioned proximate the entrance to the blower system (e.g., 3 feet (or any desired predetermined distance)). When a vehicle passes by the sensors 112, the controller system 110 determines that a vehicle is approaching the blower station and, as such sends a signal to the actuators to cause the actuator 206 to lift the gates 200 off of the intake 202 to the impeller chamber 204, thereby allowing the blowers 102 to provide a full blow load. Similarly, the control system can cause the actuators 206 to pull the gate 200 back over the intake 202 to place the blowers 102 in the closed configuration. For example, sensors can be place proximate the exit of the blower station (e.g., 10 feet past the blower station (or any other desired predetermined distance)) such that the control system is operable for determining when the vehicle has left the blower station. As another example, the control system can simply use a timed out operation, such as opening the gate 200 for a predetermined amount of time (e.g., 10 seconds, 15 seconds, etc.) after sensing the approaching vehicle, after which the control system causes the actuators 206 to pull the gate 200 back over the intake 202 to place the blowers 102 in the closed configuration. Thus, as can be appreciated by those skilled in the art, there are several techniques by which the gates 200 can be opened and closed to effectively open only when a vehicle is passing by the blower station.

[0024] Lastly, when the gate 200 is in a closed position, it greatly reduces the noise output (in decibels) as compared to a generic system with no smart gate. It also reduces the noise output when in the open position, from 94 decibels to 88 decibels. These comparisons can be seen in more detail in FIG. 5. Specifically, FIG. 5 is a chart 500 illustrating noise level comparisons between a blower with no gate 502, a blower with an open gate 504, and a blower with a closed gate 506. As shown, the noise emitted by a blower with a closed gate 506 is much less than a blower with no gate 502 or a blower with an already opened gate 504, thereby dramatically reducing noise pollution.
