Description

Technical Field

[0001] The utility model relates to the field of solar power generation equipment, in particular to a floating and submersible offshore solar power generation device. Background Technique

[0002] With the gradual depletion of non-renewable energy and the adjustment of the energy structure under the "dual carbon" strategy, the efficient utilization of renewable and clean energy has become an inevitable trend. Solar energy is one of the indispensable energies in the development process of the earth. Solar power generation has gradually become the main development and utilization method of solar energy, which has the advantages of absolute cleanliness, no risk of exhaustion, wide distribution, etc. However, there are also some practical problems.

[0003] For example, the installation of solar panels requires a certain geographical area, which affects the application of land resources. Therefore, solar power generation is mostly built in remote areas or at sea. Building a solar power generation device at sea can not only save land resources but also reduce the impact on people's lives. However, the currently commonly used offshore solar power generation devices are relatively unstable under windy and wavy conditions and are extremely vulnerable to damage. Therefore, we propose a floating and submersible offshore solar power generation device, which can effectively improve the safety of the device. Summary of the Invention

[0004] The purpose of the utility model is to provide a floating and submersible offshore solar power generation device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A floating and submersible offshore solar power generation device includes a square slope bracket. Solar photovoltaic panels are installed on the slopes of the bracket. An air pump is installed at the center position below the bracket, and floating barrel frames are welded to the four sides respectively. Floating barrels are installed in the floating barrel frames. Connecting ropes are tied below the floating barrel frames. The connecting ropes are connected to mooring cables. The other end of the mooring cable is an electric cable winch. The electric cable winch can control the retraction and release of the mooring cable. The air pump and the electric cable winch obtain power supply through a power supply control line and realize remote control of the inflation and deflation function and the chain retraction and release function. The lower end of the electric cable winch is connected to an anchor chain and is anchored to the seabed.

[0007] As a further scheme of the utility model: The solar photovoltaic panels are equipped with a storage battery to store electric energy. The solar photovoltaic panels and the storage battery have a waterproof function and will not cause short circuits, rust, etc. due to diving into the water.

[0008] As a further scheme of the utility model: The four connecting ropes should be of the same length and connected to one point to keep the forces on the four corners of the whole device balanced.

[0009] As a further solution of the utility model: A pressure detector is installed on one side of the square slope bracket, which can detect the diving depth when the device sinks into the water.

[0010] As a further solution of the utility model: The floating cylinder is a deformable solid inflatable device. After deflating, its volume decreases, and its position is restricted by the floating cylinder frame. The air pump is connected to the floating cylinder through an air charging pipe, which can realize the inflation and deflation functions of the floating cylinder.

[0011] As a further solution of the utility model: The air pump can be controlled to inflate and deflate the floating cylinder. When the wind and wave conditions are severe, the floating cylinder is deflated to reduce the buoyancy of the device. After diving to a certain depth, the floating cylinder is inflated to increase the buoyancy, so that it can float stably.

[0012] As a further solution of the utility model: The electric cable winch meets the watertight requirements and is driven by electricity. There is a tension detector inside to detect the tension state of the mooring cable and send it back to the console to realize the winding and unwinding of the mooring cable.

[0013] As a further solution of the utility model: When the wind and wave conditions are severe, control the electric cable winch to wind up the mooring cable to make the device sink into the water and maintain a certain height to float stably. When the conditions improve, let out the mooring cable to make the device rise in height and return to the floating state on the sea surface again.

[0014] As a further solution of the utility model: The power supply control line provides electrical energy for the air pump and the electric cable winch, and transmits command signals to remotely control the air pump to inflate and deflate and the electric cable winch to wind and unwind the chain.

[0015] As a further solution of the utility model: The lower end of the electric cable winch is connected to an anchor chain, and the device is fixed to the seabed through an anchoring system.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows: When the wind and waves are relatively large, the device can dive into the sea water to a certain height through the cooperation of the floating cylinder and the electric cable winch, reducing the load of the wind and waves on the solar power generation device, reducing the risk of damage, enhancing the ability to resist harsh environments, further extending the service life of the offshore solar energy device, having high practicability and broad market prospects, and being suitable for popularization and use.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] In the drawings, components with the same structure are denoted by the same numeral labels, and the drawings do not stipulate the dimensions of each component, and the actual construction shall prevail. For example, the size and dimensions of the buoy 6 do not need to be enlarged in proportion according to the drawings, but are calculated according to the buoyancy of the overall device after construction.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a floating and submersible offshore solar power generation device includes a square slope bracket 3. A solar photovoltaic panel 1 is installed on the slope of the bracket. The solar photovoltaic panel 1 is equipped with a storage battery 2 to store electric energy. A pressure detector 8 is installed on one side of the square slope bracket 3, which can detect the diving depth when the device sinks into the water. An air pump 4 is installed at the center position below the bracket, and buoy frames 5 are welded to the four sides respectively. Buoys 6 are installed inside the buoy frames. The air pump 4 is connected to the buoy 6 through an air charging pipe 7, which can realize the air charging and discharging function of the buoy 6. Connecting ropes 9 are tied to the four corners of the square slope bracket 3. The connecting ropes are connected to a mooring line 10. The other end of the mooring line is an electric mooring winch 11. The electric mooring winch can control the retraction and release of the mooring line 10 to realize the floating and submersibility of the entire device. The air pump 4 and the electric mooring winch 11 obtain power supply through a power supply control line 12, and realize the remote control of the air charging and discharging function and the chain retraction and release function. The lower end of the electric mooring winch is connected to an anchor chain 13, which is anchored to the seabed.

[0026] Embodiment 2:

[0027] When the buoy 6 is filled with air, the buoyancy force on the entire device is greater than the gravity. The inflation volume of the buoy is adjusted to control the sinking and floating of the device. When in the floating state, the buoy 6 is deflated, and the buoyancy force on the entire device becomes less than the gravity, and the device begins to sink. The diving depth is judged according to the data of the pressure detector 8. After diving to a relatively stable water area, the air pump 4 inflates the buoy 6 in the first stage, so that the buoyancy force increases to be the same as the gravity. After being judged by the pressure detector 8 that the device is in a stable suspension state, when the wind and wave conditions improve, the buoy 6 is inflated in the second stage to make the device float upward until it reaches a stable floating state on the water surface.

[0028] Embodiment 3:

[0029] The electric cable winch 11 is controlled by an external signal. During the deflation process of the buoy 6, the device begins to sink, and the mooring cable 10 changes from a tensioned state to a relaxed state. The console sends a signal to control the electric cable winch 11 to shorten the mooring cable 10. When the device sinks to the required position and the buoy 6 starts to be inflated in the first stage, after it is judged by the tension detector 14 that the mooring cable 10 is in a tensioned state when the device is in a stable suspension, a signal is sent to control the cable winch 11 to stop working. When the buoy 6 is inflated in the second stage, the cable winch 11 is simultaneously controlled to release the mooring cable 10, and it stops working when the device reaches the floating state on the water surface, keeping the mooring cable 10 in a tensioned state.

[0030] The working principle of the present utility model is as follows: When it is predicted that the wind and wave conditions tend to be severe, the air pump 4 and the electric cable winch 11 are remotely controlled to complete the process of deflating the buoy 6 and winding up the mooring cable 10 by the electric cable winch 11, so that the entire device sinks underwater. The depth of the device is judged by the pressure detector 8. After it reaches a certain depth, the air pump 4 is controlled to inflate the buoy 6 in the first stage to achieve stable suspension. When the external wind and waves tend to be stable, the buoy 6 is inflated in the second stage, and the electric cable winch 11 releases the mooring cable 10 to make the device re-emerge on the water surface, realizing the sinkability and floatability of the entire device.

[0031] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
