MECHANICAL ENGINE FOR THE GENERATION OF ENERGY THROUGH WATER MOVEMENT, refers to a mechanical motor (1) to (41), with their auxiliary sets, with the objective of generating mechanical and electrical energy, or both, being plants electric lines with this system can be built on the banks or inside the sea, river or islands, where the cost benefit of the energy by the conventional way, does not become compensating, or practically inaccessible places, but that have waves, tides, or level differentials in waters. As these sources of energy, in water there are in abundance on the planet, possible future plants of this system, may be more spread out, and in greater quantity, thus reducing the number of posts, towers, compensation equipment, components, and transmission wires. In case of use in water navigation, this engine can be used to replace, totally or partially, conventional fuels and engines, for mechanical handling, and the generation of electric energy on board.

The device, herein to be known as the HydroQueen, is a device to convert the kinetic energy of a fluid into electrical energy using a single or multiple helix shaped vertical paddles. The helix shaped vertical paddle rotates around its axis from the force placed on face of paddle by the movement of the fluid. The electricity is generated by the rotation of the paddle around its axis. The number, length, radii, and pitch of the paddles may vary depending on the location and/or application.

A wave energy capture system includes: a supporter frame fixed on the ground or the sea; a lever boom coupled to the supporter frame by a pivot; an energy-capturing member connected to one end of the lever boom to capture wave energy from the sea; a position control member connected to the other end of the lever boom to control the position of the lever boom; and an energy conversion member connected to the lever boom to convert vertical movement of the lever boom into power.

A float-linkage device for wave-energy electricity generation includes a float coming with two moving braces attached to two sides thereof. The two moving braces are pivotally connected to corresponding ends of upper and lower links. The upper and lower links each have an opposite end thereof pivotally connected to a transmission link. The transmission link further has an opening for receiving a one-way bearing, thereby forming a float-link unit. A plurality of the float-link units are linked by each having a pivot hole at one end of the moving brace of the float engaged with a boom of a prop, and having a pivot hole of the one-way bearing engaged with a main boom of the prop. A gear is provided on the main boom of the prop and is engaged with a pinion provided on a power-generating device installed on the prop.

A system and method for generating energy by exploiting changes in atmospheric pressure. A system is provided that includes a pair of submerged vessels, each vessel containing a fluid; a mechanism for alternatively raising and lowering the submerged vessels to cause the fluid to expand and contract; a system for capturing mechanical energy resulting from the expansion and/or contraction; and a system for converting the mechanical energy to electrical energy.

A clip-on fan includes a specialized clamping clip 56 that is attached to rectangular or cylindrical tent poles that are commonly used for grow tents; wherein fans are essential components for growing in tents and the current designs clip-on fans do not meet the needs of indoor growers; the clip-on fan comprising a fan assemblage and clip clasp assemblage arranged at the base of the complete product, wherein the clip 5 is able to grasp to the vertical tubular structure of a grow tent; the grasping clasp 5 assembly consisting of: a left clip plate 51, a right clip plate 52, a clip plate rotation shaft 53, a clip spring 54, a fan connection hole 55 and, a clip clamp opening 56; the left and right clip plates are connected in a bilateral symmetry through the clip plate rotation shaft at the central connection position.

A reciprocating fluid-energy device to be used in a flowing fluid, having a foil, an upstream support member, a downstream support member, and a frame, where the frame retains the device in place within the flowing fluid, the support members movably attach the foil to the frame, and the foil moves laterally back and forth across the direction of the flow of the fluid, with changes in direction of the movement of the foil occurring automatically and spontaneously without external intervention other than the force of the flowing fluid.

An assembly includes a first and a second member, where the second member has a fork-shaped cross section with a main body and two substantially parallel walls that each comprise at least one through hole and the first member is arranged between the two walls of the second member, having a through hole. The through hole of the first member and the through holes of the second member define a channel. A connector is axially insertable in the channel to an end position and consecutively expandable radially relative to said channel, to connect the first and second member relative to each other. The connector, in an expanded state thereof, pushes the first member against the main body of the second member to define a pre-tensioned connection between the first member and the second member. A method of assembling a first and a second member.

An underwater turbo-generator unit for producing electrical power has a pressure-resistant shell that defines a sealed internal chamber. At least one water inlet extends through the shell to effect fluid communication between the chamber and a body of water surrounding the shell. A turbine is supported within the chamber to turn on a spin axis in response to admission of a flow of water into the chamber via the or each water inlet. The shell can be arranged to maintain a gas-filled space within the chamber, facilitating the use of a Felton turbine that turns about a vertical spin axis. The or each water inlet communicates with at least one tubular penstock structure that can be supported by the unit outside the shell. The chamber communicates with, and drains water into, a fluid storage volume such as a pipeline positioned at a level beneath the chamber.

A fan device for a table of a user comprising a fan, a pivot pin for tilting and a mechanism for connection to a desktop in the form of two clips or a bracket with screws. It is positioned between the user and the desktop. The pivot pin for tilting is positioned beyond the edge of and within the thickness of the desktop, allowing for a maximum height of protrusion of the fan above and below the desktop less than the dimensions of the fan and allowing to direct the air flow to the greater part of the user area. The technical result is the decrease in the height of protrusion of the fan above and below the desktop.
