Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a floating buoy device for supporting floating photovoltaic panels. Background Art

[0002] With the rapid development of social economy, the demand for electric energy in industrial production and daily life is increasing, and the pressure on power supply is also increasing. The use of traditional fuels as a source of electricity consumes conventional energy on the one hand, and causes certain pollution to the environment on the other hand, which restricts economic development to a certain extent. Solar energy, as an ideal renewable energy source, has been valued by many countries.

[0003] At present, most photovoltaic power stations are built on land or roofs, while there are few built on water. Water photovoltaic has many advantages as follows: 1. Preserve valuable land for agriculture, tourism or industrial construction; 2. Turn undeveloped water into renewable energy and sustainable profit; 3. Relatively low rental prices and construction costs accelerate investment recovery; 4. The cooling effect of water on photovoltaic panels and cables brings higher power output; 5. The shielding effect of water photovoltaic arrays on water inhibits algae growth and improves water quality; 6. Reduce evaporation water for agricultural irrigation and drinking water production; 7. Does not affect water quality and can recycle materials. Water photovoltaic is modeled after the ground or roof photovoltaic power station model, setting up brackets in the water and then laying photovoltaic modules. This method has high construction cost, difficulty in construction and daily maintenance, and has great limitations on the water environment, so it is not suitable for large-scale promotion; at the same time, the stability of water photovoltaic power generation modules in the existing technology is poor when encountering waves, which affects the efficiency of photovoltaic power generation.

[0004] In the prior art, the Chinese utility model patent "A Water Photovoltaic Bracket" with application number CN202320626075.5 uses cables to hang four hooks, and a weight is hung on the other end of the cable and sunk to the bottom of the shallow sea to prevent it from drifting away. The floating platform is suspended on the sea surface, and the four connecting blocks can prevent the floating platform from swinging sharply. At the same time, under the weight of the counterweight ball, the connecting rod can always be in a vertical state, thereby ensuring that the photovoltaic panel can maintain a horizontal state to the greatest extent. However, the size of the bracket is fixed and cannot be adjusted according to on-site needs and used multiple times. Utility Model Content

[0005] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a water buoy device for supporting water photovoltaic panels. The buoyancy seat adopts a splicing design, so that the size of the device can be flexibly adjusted as needed to adapt to the layout requirements of different waters and photovoltaic panels.

[0006] The technical solution of the utility model is as follows:

[0007] A floating buoy device for supporting a floating photovoltaic panel comprises a buoyancy seat, a photovoltaic panel is installed above the buoyancy seat, the buoyancy seat comprises a plurality of bases spliced ​​together to form a rectangle, a buoy is fixedly arranged at the bottom of the base, a mounting frame is fixedly arranged inside the buoyancy seat, and a counterweight is connected to the bottom of the mounting frame.

[0008] Furthermore, the buoyancy seat also includes four connecting rods passing through several of the bases, an insert block is provided at a joint on one side of the base, and a slot is correspondingly provided at a joint on the other side of the base, the insert block and the corresponding slot are snap-connected, and the connecting rod passes through several snap-connected insert blocks and slots.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model enhances the stability of the entire device on the water surface through the design of the buoyancy seat, combined with the counterweight block and the balancing ball. The weight adjustment of the counterweight block makes the center of gravity of the device lower, and the balancing ball helps to reduce excessive shaking of the device in the waves, thereby improving the stability of the photovoltaic panel on the water surface. At the same time, the elastic design of the tension rope can be automatically adjusted under the action of waves to ensure that the counterweight block sinks firmly to the bottom of the water and maintains the stability of the entire device.

[0021] In order to make the contents of the present invention easier to understand, the technical solution of the present invention is further described below in conjunction with specific implementation methods and drawings, but the present invention is not limited thereto.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a floating buoy device for supporting a floating photovoltaic panel, comprising a buoyancy seat 6, a photovoltaic panel 2 is installed above the buoyancy seat 6, the buoyancy seat 6 comprises a plurality of bases 61 spliced ​​together to form a rectangle, a buoy 62 is fixedly arranged at the bottom of the base 61, the base 61 and the buoyancy 62 can both float on the water surface, a mounting frame 4 is fixedly arranged inside the buoyancy seat 6, a counterweight 3 is connected to the bottom of the mounting frame 4, the counterweight 3 is a solid metal block, and the counterweight 3 can lower the center of gravity of the entire buoy device, so that the buoy device is more stable when installed on the water surface.

[0023] As a further preference of this embodiment, the buoyancy seat 6 also includes four connecting rods 63 that penetrate several bases 61, an insert block 64 is provided at the joint on one side of the base 61, and a slot 65 is correspondingly provided at the joint on the other side of the base 61, the insert block 64 and the corresponding slot 65 are snap-connected, and the connecting rod 63 penetrates several snap-connected insert blocks 64 and slots 65, and the buoyancy seat 6 can splice the base 61 according to the required size, so that the device can flexibly adjust the size as needed to adapt to the layout requirements of different waters and photovoltaic panels.

[0024] Combination Figure 4A cavity 621 is provided in the buoy 62, and a pin rod 622 is vertically provided in the cavity 621. A balancing ball 623 is slidably connected to the circumferential surface of the pin rod 622, and seawater cannot enter the cavity 621. When encountering upward waves, the entire buoyancy seat 6 moves upward, and the weight of the balancing ball 623 is greater than the weight of the buoyancy cylinder 62 shell. The upward movement amplitude of the balancing ball 623 will be smaller than the movement amplitude of the buoyancy seat 6; similarly, when encountering downward waves, the downward movement amplitude of the balancing ball 623 is smaller than the movement amplitude of the buoyancy seat 6. Therefore, the balancing ball 623 can reduce the overall activity amplitude of the buoyancy seat 6, thereby making the buoyancy seat 6 run more smoothly.

[0025] As a further preference of this embodiment, the mounting frame 4 is a rectangular metal frame, and the mounting frame 4 includes a rectangular bracket 41 fixedly arranged on the inner wall of the buoyancy seat 6, and a support seat 42 is arranged above the rectangular bracket 41, and a tension rope 5 is vertically arranged at the bottom of the support seat 42, and the other end of the tension rope 5 is connected to the counterweight block 3, and the counterweight block 3 is installed on the mid-vertical line of the support seat 42. The tension rope 5 is an elastic rope. When waves come on the water, the tension rope 5 is subjected to tension and can be adaptively extended or retracted to ensure that the counterweight block 3 sinks to the bottom of the water.

[0026] As a further preferred embodiment of the present embodiment, a mounting seat 1 is fixedly provided on the top of the support seat 42 , an inclined groove is provided on the upper surface of the mounting seat 1 , and the photovoltaic panel 2 is installed in the inclined groove.

[0027] As a further preference of this embodiment, the base 61 is a hollow structure and has a large surface area. At the same time, the base 61 is provided with arc chamfers on the outside of the buoyancy seat 6 to prevent maintenance personnel from being injured when walking on the buoyancy seat 6, thereby improving safety.

[0028] Working principle of the utility model

[0029] When building the above-water support device for the photovoltaic panel 2, the adjacent bases 61 are snap-connected by means of the plug blocks 64 and the slots 65 according to the required size, and the connecting rods 63 penetrate the several bases 61, and at the same time, the several bases 61 formed by the snap-connection are fixedly arranged on the outside of the rectangular bracket 41 in turn, so that the multiple bases 61 are spliced ​​together to form a rectangular buoyancy seat 6, thereby improving the stability of the entire buoyancy seat 6, and finally the photovoltaic panel 2 is installed in the inclined groove of the mounting seat 1. During actual use, a tension rope 5 and a counterweight block 3 are provided at the bottom of the support seat 42.

[0030] When encountering upward waves, the entire buoyancy seat 6 moves upward, and the weight of the balancing ball 623 is greater than the weight of the buoyancy tube 62. The upward movement amplitude of the balancing ball 623 is smaller than the movement amplitude of the buoyancy seat 6. Similarly, when encountering downward waves, the downward movement amplitude of the balancing ball 623 is smaller than the movement amplitude of the buoyancy seat 6. The balancing ball 623 can reduce the overall movement amplitude of the buoyancy seat 6, thereby making the buoyancy seat 6 run more smoothly. The utility model can ensure that the buoyancy seat 6 is stably installed on a horizontal surface. When encountering waves, the buoyancy seat 6 has a small movement range and runs more smoothly.
