Technical Field

[0001] The utility model relates to the field of ocean current energy power generation, in particular to an ocean current energy power generation device. Background Art

[0002] At present, a Chinese utility model with announcement number CN210343572U discloses an ocean current power generation device, including a floating body, a hyperbola cylinder is connected to the left side of the lower end of the floating body through a connecting rod, a hydro-turbine generator is fixedly installed in the middle of the hyperbola cylinder, a fixing column is fixedly connected to the right side of the upper end of the floating body, a mounting frame is fixedly connected to the upper end of the fixing column, a first rotating shaft is horizontally rotatably connected in the mounting frame, a blade is fixedly connected to the left end of the first rotating shaft, a first bevel gear is fixedly connected to the side wall of the first rotating shaft, a second rotating shaft is rotatably connected inside the fixed column, and the second rotating shaft passes through the floating body, a second bevel gear is fixedly connected to the upper end of the second rotating shaft, and a third bevel gear is fixedly connected to the lower end of the second rotating shaft. The utility model increases the flow speed of water in the hyperbola cylinder, increases the water flow speed passing through the hydro-turbine generator, increases the impeller speed of the hydro-turbine generator, and thus improves the power generation efficiency of the hydro-turbine generator.

[0003] The existing ocean current power generation device cannot automatically adjust according to the direction of the ocean current. Nowadays, ocean current power generation uses a hydro-turbine generator to generate electricity under the action of the water flow, but the direction of the water wheel of the hydro-turbine generator is fixed. Since the direction of the ocean current changes randomly, if the blades of the hydro-turbine generator are tilted from the direction of the ocean current, the rotation speed of the blades will be reduced, which will cause the power generation efficiency to decrease. In order to solve the above problems, we propose an ocean current power generation device. Utility Model Content

[0004] The utility model aims to provide an ocean current energy power generation device, which has the advantage of being able to automatically adjust according to the direction of the ocean current.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] The invention discloses an ocean current energy power generation device, comprising a shell, a piston cylinder bolted between the inner walls of the shell, a piston slidably sleeved on the inner wall of the piston cylinder, the piston dividing the piston cylinder into two upper and lower chambers, a first spring arranged between the piston and the bottom of the piston cylinder, a connecting rod connected to the top of the piston, and the connecting rod penetrates the inner walls of the piston cylinder and the shell, a box body is arranged on the top of the connecting rod, triangular blocks are horizontally arranged on both sides of the box body, and the upper and lower sides of the piston cylinder are provided with power generation structures that can generate electricity by sliding the piston up and down.

[0007] Preferably, the power generation structure comprises:

[0008] A cylinder, wherein the cylinder is vertically fixed in the shell, a rotating shaft is coaxially arranged in the cylinder, and a plurality of rotating blades are arranged on the rotating shaft along the circumferential direction;

[0009] A generator, the generator is fixed in the housing and is drivingly connected to the rotating shaft;

[0012] Preferably, the lower end of the connecting rod is rotatably arranged on the piston, and a guide plate is provided on the box body.

[0013] Preferably, a connecting sleeve is provided at the bottom of the box body, the upper end of the connecting rod is inserted into the connecting sleeve, and the inner wall of the connecting sleeve is threadedly connected with a bolt.

[0014] Preferably, an anti-slip sleeve is fixedly sleeved on the surface of the rotating cylinder.

[0015] Preferably, one end of the card connector is wedge-shaped.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The utility model allows the sea current to pass through the triangular block. When the downward pressure of the sea current on the triangular block is greater than the elastic force of the first spring, the triangular block drives the piston to move downward, presses the seawater in the chamber below the piston into the cylinder, and at the same time causes the first spring to contract under pressure, and the seawater flows into the cylinder, driving the rotating shaft to rotate counterclockwise, so that the generator generates electricity. When the downward pressure of the sea current on the triangular block is less than the elastic force of the first spring, the first spring pushes the piston and the triangular block to move upward, so that negative pressure is formed in the chamber below the piston, and water is pumped from the outside into the cylinder through the second water pipe, and then drives the rotating shaft to rotate counterclockwise, so that the generator generates electricity. The up and down movement of the piston is used to make the rotating shaft rotate continuously counterclockwise, thereby improving the power generation efficiency of the generator;

[0018] 2. Similarly, when the triangular block drives the piston to move downward, negative pressure is formed in the chamber above the piston, and water is pumped from the outside into the cylinder through the second water pipe, and then the shaft is driven to rotate counterclockwise, so that the generator generates electricity. When the first spring pushes the piston and the triangular block to move upward, the seawater in the chamber above the piston is squeezed into the cylinder, driving the shaft to rotate counterclockwise, and then discharged from the second water pipe. The up and down movement of the piston enables the upper and lower generators to continuously generate electricity, and the rotation directions of the shafts of the upper and lower generators are always consistent, reducing the impact of frequent reversal of the shaft on the generator and improving the power generation efficiency.

[0019] 3. When the direction of the ocean current changes, a pressure difference is generated on both sides of the guide plate, causing the box connected to the triangular block to rotate, so that the top angle of the triangular block is facing the direction of the incoming flow, thereby achieving the purpose of automatic adjustment according to the direction of the ocean current, ensuring the efficiency of power generation and improving practicality;

[0020] 4. The connecting rod is driven to move by rotating the rotating cylinder, and the movement of the connecting rod drives the clamping joint to move. The movement of the clamping joint disengages the clamping joint from the clamping groove, and the filter cylinder is removed to facilitate cleaning of impurities on the filter net. During installation, the filter cylinder is installed into the fixed cylinder, and the clamping joint is clamped with the clamping groove under the action of the second spring, thereby facilitating the rapid assembly and disassembly of the filter cylinder.
