Description

Mechanical arm transmission type tidal power generation device

technical field

The invention relates to a power generating device, especially a tidal power generating device.

Background technique

At present, the tidal power generation device is to build a watertight dam in the bay to form a storage capacity. There is a gate on the dam, and a hydroelectric generator set is installed at the gate. Its disadvantages are: the investment in building a dam in the bay is too large, the construction is difficult, and it is also limited by the natural environment, making it difficult to popularize tidal power generation.

Contents of the invention

The object of the present invention is to provide a manipulator-driven tidal power generation device which is easy to process and manufacture, has low investment and is not limited by the natural environment.

The invention is mainly composed of a platform, a column, a floating body, a mechanical arm, a gear set, a gearbox and a generator. Wherein, the top surface of the platform used for loading and operating can be a flat plate, or a plane made of a frame. The platform can be of various geometric shapes, and its lower periphery is fixed with the upper ends of 4-8 columns. The lower end is set on the seabed. It can be directly fixed on the seabed in the form of piles, or the lower end of the column can be connected to the ballast tank on the seabed. The ballast tank is made of metal (external anti-corrosion layer) The box body is made, and ballast such as concrete, iron block, water or other heavy objects are arranged in the box, and the ballast tank can be used as the base of the whole equipment. The column can be made of a variety of materials such as all metal, reinforced concrete, or a metal cylinder (outer anti-corrosion layer) and concrete inside. In the area limited by the above-mentioned column, a floating body is provided. The floating body is a box made of metal (with an anti-corrosion layer outside), and ballasts such as concrete, iron blocks, water or other heavy objects are placed in the box, and the box Body weight + ballast weight is equal to 1/2 the volume of water displaced by the tank, which is equal to the buoyancy generated by 1/2 of the tank, so that it can generate falling gravity when the tide is falling. Preferably, the part adjacent to the floating body and the column is provided with a sliding pair, which can not only reduce the resistance of the floating body moving up and down, but also keep a certain distance between the floating body and the column, so that the floating body can only move up and down with the tidal head. Other displacements cannot be produced to keep the mechanical arm mounted on the floating body moving within a specified range. The mechanical arm is composed of three metal rods hinged together, the lower end of which is hinged on the connecting piece of the floating body, and the upper end passes through the corresponding through hole of the above-mentioned platform, and is hinged with a transverse shaft, which is set on the driving gear The spoke plate can be vertically fixed on the spoke plate of the gear, or can be inserted in the through hole of the spoke plate of the driving gear. The two adjacent metal rods of the mechanical arm are respectively connected to both ends of a hydraulic part, wherein the hydraulic parts connected to the middle and lower metal rods can adjust the angle between the two metal rods and position them according to the tide level difference, so as to The purpose of adjusting the length of the mechanical arm is achieved; the hydraulic parts connected with the middle and upper metal rods only play a supporting role when generating alternating current, and not only play a supporting role when generating direct current, but also play a reversing role. When the tide is high, the buoyancy of the floating body pushes the mechanical arm to move upwards, so the horizontal shaft drives the driving gear to rotate upwards. When the horizontal shaft turns to the highest position of the driving gear, the horizontal shaft automatically falls and turns back, forcing the whole system to stop. Reversed, this two-way rotation produces alternating current, which is a form of electricity generation. Another way of generating electricity is: the horizontal shaft hinged at the upper end of the mechanical arm is set in the arc-shaped through hole concentric with it on the web plate of the driving gear. A support hole with an inclined edge, and the horizontal axis is inserted in the support hole. When the horizontal shaft turns to the highest position of the driving gear, operate the hydraulic parts to move the horizontal shaft to the front of the bar hole and cross the center line, so the horizontal shaft drives the driving wheel to continue to rotate in the same direction. When it is close to the lowest point of the driving gear, operate the hydraulic parts again Move the horizontal axis to the front of the bar hole and cross the center line, forcing the driving gear to rotate in one direction to generate direct current. The above-mentioned driving gear meshes with the pinion of the driven tower gear (the tower gear is two coaxial gears with different diameters and the end faces are connected). The tooth pitch of the driven tower gear pinion is greater than the tooth pitch of the large gear . Above-mentioned driven tower gear can be 1-5 groups according to diameter size, to realize multistage speed-up. The bull gear of the final driven tower gear meshes with the input gear of the generator gearbox. This gearbox can also realize speed-up, and it works together with the above-mentioned driven tower gear, and when it is transmitted to the output gear shaft of the gearbox, its rotating speed can reach the required 2000-3000 rpm of the generator set. The output gear shaft of the gearbox is connected with the generator rotor. The rotating shafts of the above-mentioned driving gear and the driven tower gear are respectively arranged on the bracket. Preferably driving gears are identical two, and discontinuous connecting rod is established between them, and transverse axis passes through the bar-shaped through-hole of two driving gears simultaneously, makes it rotate synchronously. Above-mentioned mechanical arm is arranged between two driving gears, so the driven tower gear that links to each other with driving gear is four groups, and the corresponding gear box and generator are four groups.

When the tide rises, the sea water rises, and the floating body moves upward accordingly, establishing a stable buoyancy. The driving gear is driven by the mechanical arm to rotate accordingly, and then driven by the multi-stage driven tower gear. The speed of the final driven gear can reach 10. The rotation speed transmitted to the generator rotor after passing through the gearbox is about 2000-3000 rpm, which can realize tidal power generation. When the tide falls, the rack descends to establish a stable gravity, and the gear rotates in the opposite direction. The power generation process is the same as that of the high tide. The configuration of unit capacity is determined according to the size of the displacement volume of the floating body.

Compared with the prior art, the present invention has the following advantages:

1. Simple structure, easy processing and manufacturing, less investment;

2. Not limited by the natural environment, it can be built as long as it is in the sea area of 8-10 meters, especially suitable for use in remote islands and other areas.
