Description

Rack and pinion offshore floating platform wave engine

technical field

The invention relates to an ocean wave energy engine, in particular to a rack-and-pinion wave engine for an offshore floating platform.

Background technique

At present, energy is in short supply, and at the same time, the burning of coal and oil as the main fuel causes great pollution to the environment. Green energy, such as solar energy, wind energy, and wave energy have huge energy, are inexhaustible, and can be replaced Coal, oil, no pollution, no green features of products.

The main defects of existing ocean wave energy engines are as follows: firstly, due to the contact of the rotating mechanism with seawater, the anti-corrosion performance is poor and maintenance is inconvenient; secondly, the structure is complicated, and the cost and maintenance cost are relatively high; The stability of the platform is poor, and the transmission efficiency is not high; Fourth, because the ocean is too deep, the cost of fixed offshore platform columns is too high.

Contents of the invention

The purpose of the present invention is to provide a rack-and-pinion wave engine for offshore floating platforms with simple structure, good anti-corrosion performance, good transmission mechanism stability, high transmission efficiency, low cost and convenient maintenance.

To achieve the above object, the present invention can take the following technical solutions:

A rack-and-pinion type sea floating platform wave engine of the present invention includes at least two groups of wave energy transmission units, each group of wave energy transmission units includes a square buoy made of stainless steel and is fixed on the top surface of the square buoy The square guide rod at the central part is provided with guide rails on the opposite sides of the square guide rod. A rack is provided on the other side, and the rack is engaged with a transmission gear. An overrunning clutch is provided on the inner periphery of the transmission gear, and the overrunning clutch is installed on a power output shaft provided on the offshore platform.

Preferably, there are two groups of wave energy transmission units, and the two groups of wave energy transmission units are symmetrically arranged on both sides of the floating offshore platform, and the overrunning clutches of the two wave energy transmission units share one power output shaft.

As a preference, a flywheel and a gear transmission device are installed on the power output shaft between the transmission gears, and the gear transmission device is connected to the generator drive, and a plurality of gears for supporting the power output shaft are also arranged on the floating platform in the sea. Bearing support.

Preferably, the offshore floating platform is a floating drilling platform, or a ship, or a floating island.

Compared with the prior art, the beneficial effect of the present invention is: due to the adoption of the above technical solution, at least two groups of wave energy transmission units are provided, each group of wave energy transmission units includes a square buoy made of stainless steel, fixed on the The square guide rod at the center of the top surface of the square buoy is described. Guide rails are provided on the opposite two sides of the square guide rod. The other side of the square guide rod is provided with a rack, which meshes with the transmission gear, and the inner circumference of the transmission gear is provided with an overrunning clutch, and the overrunning clutch is installed on the power output of the offshore platform. On the shaft, the operation process is as follows: when the sea waves rise or fall, the square buoys of multiple wave energy transmission units are driven to float up alternately, and the floating square buoys drive the transmission gear to rotate through the rack on the square guide rod. At this time, the overrunning clutch is self-locking, which drives the power output shaft to rotate. When the sea wave descends, under the action of its own weight, the square buoy, together with the square guide rod and the rack, descends, driving the transmission gear to rotate in the opposite direction. At this time, the overrunning clutch and the power output Shaft separation, this structure of the present invention has only a few transmission parts for converting wave energy, simple structure, good transmission stability when the guide rail resists wind and waves, high transmission efficiency, easy guide rail replacement, low cost, and convenient maintenance. With this structure, only the square buoy made of stainless steel floats on the sea surface, and has good anti-corrosion performance. When the sea level changes within a certain range, the structure of the present invention does not need to adjust the height of the floating platform on the sea. The rack can still be meshed with the transmission gear for transmission. Compared with the fixed offshore platform, the floating platform can save the cost of setting up columns in the deep sea, greatly reduce the cost, and improve the efficiency. The lifting effect is good.

The further beneficial effect of the present invention is: the flywheel is installed on the power output shaft, on the one hand, it can store energy, and on the other hand, it can balance the speed of the power output shaft by virtue of its own inertia, which is beneficial to drive the generator to generate electricity.
