Description

Technical Field

[0001] The invention relates to a damping disc structure. Background Art

[0002] With the development of economy, fossil raw materials are increasingly in short supply, and energy problems have gradually become a global problem. Vigorously developing and utilizing marine energy has become a strategic choice for major coastal countries in the world, including China, which has promoted the development of marine wave energy conversion technology. The oscillating float power generation device stands out among many types of wave energy power generation devices with its simple structure, high energy conversion rate, and wide frequency response. At present, most oscillating float wave energy power generation devices only use anchor chains and anchors for positioning or weld a circular plate directly to the lower end of the oscillating float wave energy power generation device as a damping disk. The above methods have the following shortcomings: 1. It is impossible to adjust the draft depth of the float; 2. The stability is poor, and it is easy to swing sharply or even overturn in severe sea conditions. 3. The impact of waves causes the damping disk to form torque. The direct welding method will directly transmit this torque to the oscillating float wave energy power generation device. If the torque is too large, it will cause damage. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a damping disk structure, which can adjust the draft depth of the float by adjusting its own gravity and buoyancy, thereby improving the energy capture efficiency and overall stability of the oscillating float wave energy power generation device; on the other hand, it can eliminate torque transmission through its own rotation.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a damping disk structure, comprising a floating chamber; the floating chamber is in a ring shape, and a plurality of water-gas exchange cylinders are arranged around the floating chamber, and the plurality of water-gas exchange cylinders are interconnected.

[0006] The multiple water-gas exchange cylinders are connected via air pipes.

[0007] At least one of the multiple water-gas exchange cylinders is provided with an air inlet hole at the top.

[0008] The water-gas exchange cylinder has a cylindrical cavity at the bottom, and the bottom of the cylindrical cavity has water inlet and outlet holes. Multiple water-gas exchange cylinders are connected to the outside of the top of the cylindrical cavity, and the water-gas exchange cylinders are connected to the inside of the cylindrical cavity through the air outlet holes.

[0009] The inner circle of the buoyancy tank is also provided with a water tank.

[0010] The water tank is in a circular shape, and a plurality of counterweight adjustment blocks are fixed around the water tank.

[0011] The water tank is provided with a counterweight block positioning pin, the counterweight adjustment block is mounted on the counterweight block positioning pin, and the counterweight block positioning pin is provided with a hole.

[0012] The inner circle of the water tank has a rotation center.

[0013] The beneficial effects of the present invention are as follows: seawater can be injected into the water tank during the lowering process to increase the damping of the damping disc, so that the whole has better stability; the draft depth of the whole float can be controlled by adjusting the air-water ratio in the water-gas exchange cylinder; when the attachment of marine organisms makes the whole body too heavy and the water-gas exchange cylinder and the buoyancy tank cannot provide sufficient buoyancy, the purpose can be achieved by removing the counterweight adjustment block; when the wave current causes an impact on the damping disc to form a torque, the damping disc can rotate around the center of rotation, which can effectively avoid the torque from causing damage to the oscillating float type wave energy power generation device.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0022] Example 1

[0023] like Figures 1 to 6 A damping disk structure shown includes a floating chamber 4; the floating chamber 4 is annular, and a plurality of water-gas exchange cylinders 1 are installed around the floating chamber 4, and the plurality of water-gas exchange cylinders 1 are interconnected.

[0024] Example 2

[0025] Based on the first embodiment, a plurality of water-gas exchange cylinders 1 are connected via the gas pipe 2 .

[0026] Example 3

[0027] Based on Example 1, at least one of the multiple water-gas exchange cylinders 1 is provided with an air inlet hole 13 at the top.

[0028] Example 4

[0029] Based on Example 1, the water-gas exchange cylinder 1 has a cylindrical cavity at the bottom, and the bottom of the cylindrical cavity has an inlet and outlet hole 14. Multiple water-gas exchange cylinders 1 are connected to the outside of the top of the cylindrical cavity, and the water-gas exchange cylinders 1 are connected to the inside of the cylindrical cavity through the outlet hole 12.

[0030] Example 5

[0031] Based on the first embodiment, a water tank 3 is further installed inside the inner circle of the floating tank 4 .

[0032] Example 6

[0033] Based on the fifth embodiment, the water tank 3 is in a circular shape, and a plurality of counterweight adjustment blocks 5 are fixed around the water tank 3 .

[0034] Example 7

[0035] Based on Example 6, there is a counterweight block positioning pin 10 on the water tank 3, the counterweight adjustment block 5 is installed on the counterweight block positioning pin 10, and the counterweight block positioning pin 10 has a hole.

[0036] Example 8

[0037] Based on the fifth embodiment, the water tank 3 has a rotation center 11 in its inner circle.

[0038] Example 9

[0039] Based on the above embodiment, specifically, the water-gas exchange cylinder 1 is evenly distributed around the damping disk, connected in series through the air pipe 2 and the air pipe connector 6, and a drainage hole is opened at the lower end, and the water-gas ratio can be adjusted by controlling the internal air pressure to control its buoyancy. The water tank 3 has water injection holes on the upper and lower sides for injecting seawater; the floating tank 4 is equipped with an adjustable counterweight block positioning pin for placing the adjustable counterweight block, and a rotation center is designed in the middle. When the wave current damages the structure of the oscillating float wave energy power generation device.

[0040] The main working principle is as follows:

[0041] During the process of lowering into the ocean, seawater is injected into the water tank 3 and the water-gas exchange cylinder 1 through the water injection hole of the water tank 3 and the drainage hole of the water-gas exchange cylinder 1, respectively. At this time, the damping of the damping disk increases, and the entire oscillating float wave energy power generation device obtains better stability and is not easy to capsize. When it is necessary to adjust the draft of the float, the air-water ratio in the water-gas exchange cylinder 1 can be controlled to achieve it. When the draft of the float is too deep, gas can be filled into the water-gas exchange cylinder 1 to discharge the seawater through the drainage hole. Since the water-gas exchange cylinder 1 is evenly distributed around the damping disk and is connected and connected to each other through the air pipe 2 and the air pipe connector 6, the entire damping buoyancy increases, and then the whole floats up, and the draft of the float becomes shallower; similarly, when the draft of the float is too shallow, it can be adjusted by discharging the gas in the water-gas exchange cylinder 1, the volume of seawater in the water-gas exchange cylinder 1 becomes larger, the entire damping buoyancy becomes smaller, and then the entire power generation device sinks, and the draft of the float becomes deeper. As time goes by, when the attachment of marine organisms makes the oscillating float wave energy power generation device too heavy and the water-gas exchange cylinder 1 cannot be adjusted to the expected buoyancy effect, the counterweight adjustment block 5 installed on the buoyancy chamber 4 can be removed to further increase the buoyancy. When the wave current impacts the damping disc to form a torque, the damping disc can rotate around the rotation center to avoid the formation of torque to damage the structure of the oscillating float wave energy power generation device.
