Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation system and a construction process method thereof. Background Art

[0002] In the construction process of traditional photovoltaic power generation systems, cement mortar is usually used to cast piers on the floor. After the piers are formed, support frames are built on the piers, and then photovoltaic panels are installed on the support frames.

[0003] The support frame is fixed to the floor through the piers. The support frame is not directly fixed to the floor with screws. The casting of the piers is mainly to prevent the floor from being damaged. However, casting the piers is not only time-consuming and labor-intensive, but also costly.

[0004] Usually, photovoltaic panels are installed on support frames at a fixed angle, so the angle of the photovoltaic panels cannot be adjusted adaptively, so that the photovoltaic panels cannot receive sunlight with the optimal light-facing side, and the photovoltaic power generation effect is poor.

[0005] Furthermore, when encountering extreme weather, the photovoltaic panels are easily damaged because they are assembled together in a row and have a larger windward surface.

[0006] To this end, it is necessary to optimize and improve the above-mentioned traditional photovoltaic power generation system, abandon the traditional form of cast piers, realize the adjustable angle of photovoltaic panels to improve power generation efficiency, and make the photovoltaic panels completely foldable to prevent damage in extreme weather.

[0012] When the fluid in the water tank rises, the floating ball blocks the opening due to the buoyancy of the fluid, and friction is generated between the spherical surface of the floating ball and the opening to fix the photovoltaic panel at the current angle, and the angle adjustment rope is tightened;

[0013] When the fluid in the water storage tank drops, the float drops along with the fluid, the photovoltaic panel fits on the top of the water storage tank, and the angle adjustment rope is fastened.

[0014] In one of the embodiments, a sealing ring is provided at the opening, and the spherical surface of the float abuts against or separates from the sealing ring. The abutment between the spherical surface of the float and the sealing ring generates friction and seals the opening.

[0043] like Figure 1 and Figure 2 As shown, the present invention discloses a photovoltaic power generation system 10, comprising: a plurality of photovoltaic power generation units 100 arranged closely in a rectangular array, a water inlet pipe network 200, and a drainage pipe network 300.

[0044] Please also read Figure 3 , Figure 4 , Figure 5 and Figure 6The photovoltaic power generation unit 100 includes: a water storage tank 110, a floating ball 120, a photovoltaic panel 130, and an angle adjustment rope 140. The top of the water storage tank 110 is provided with an opening 111, the floating ball 120 is received in the water storage tank 110, the photovoltaic panel 130 is placed on the top of the water storage tank 110, the photovoltaic panel 130 and the floating ball 120 are connected by a connecting rod 150, and the photovoltaic panel 130 and the water storage tank 110 are connected by an angle adjustment rope 140.

[0045] like Figure 1 As shown, the water storage tanks 110 of each row of photovoltaic power generation units 100 are overlapped and interconnected, and the water inlet pipe network 200 is used to inject fluid into the water storage tanks 110 of each row of photovoltaic power generation units 100; the bottom of the water storage tank 110 is provided with a drainage hole 112 (such as Figure 4 , Figure 5 and Figure 6 ), the drainage network 300 is located at the bottom of the water tank 110 and is connected to the drainage hole 112, and the fluid in the water tank 110 is discharged through the drainage hole 112 and the drainage network 300.

[0046] When the fluid in the water tank 110 rises, the float 120 blocks the opening due to the buoyancy of the fluid, and friction is generated between the spherical surface of the float 120 and the opening 111 to fix the photovoltaic panel 130 at the current angle, and the angle adjustment rope 140 is tightened.

[0047] When the fluid in the water tank 110 drops, the float 120 drops along with the fluid, the photovoltaic panel 130 fits on the top of the water tank 110 , and the angle adjustment rope 140 is fastened.

[0048] The following is an explanation of the construction process and working principle of the above photovoltaic power generation system:

[0049] The construction workers first need to lay a drainage network 300 on the ground;

[0050] like Figure 1 and Figure 2 As shown, the construction workers install the photovoltaic power generation units 100 one by one in the form of a rectangular array above the drainage network 300. Several photovoltaic power generation units 100 are arranged closely in a rectangular array, and the bottom drainage holes 112 of each water storage tank 110 are connected to the drainage network 300, so that the fluid (such as clean water) in the water storage tank 110 can be discharged from the drainage network 300 through the drainage holes 112 at a later time.

[0051] During the installation of the photovoltaic power generation unit 100, the water storage tanks 110 of each row of photovoltaic power generation units 100 need to be overlapped and interconnected, which facilitates the introduction of fluid from the water storage tanks 110 at the front end of each row, and then flows through each overlapped water storage tank 110 in turn, achieving fast and convenient water filling;

[0052] like Figure 7 As shown, the water inlet pipe network 200 is installed at the front end of each row of water tanks 110, and the water inlet pipe network 200 injects the fluid into the water tanks 110 at the front end of each row. Since the water tanks 110 in each row are overlapped and interconnected, the fluid will flow through each water tank 110 in turn until all the water tanks 110 in each row are filled with a specified amount of fluid; a plurality of photovoltaic power generation units 100 form a rectangular array and are arranged closely together, which is similar to forming a large and stable base with very good wind resistance; the water tank 110 replaces the traditional column pier, and the construction workers do not need to carry cement mortar to a high place, and can directly use the existing pipes to inject water into the tank body, which is very time-saving and labor-saving;

[0053] like Figure 4 and Figure 5 As shown, when a specified amount of fluid is injected into the water storage tank 110, the fluid in the water storage tank 110 rises, and the float 120 is blocked by the buoyancy of the fluid, and friction is generated between the spherical surface of the float 120 and the opening 111. After the construction personnel adjust the photovoltaic panel 130 to a suitable angle, they tighten the angle adjustment rope 140. Under the multiple restrictions of the above-mentioned buoyancy, friction and angle adjustment rope 140, the photovoltaic panel 130 will be stably positioned at the current position; each photovoltaic panel 130 is independent of each other, which is convenient for adjusting the angle of the photovoltaic panel 130. A gap is formed between the photovoltaic panels 130, and the windward area of ​​a single photovoltaic panel 130 is small. When encountering strong winds, the strong wind can pass through the gap without blowing away the continuous photovoltaic panels 130;

[0054] like Figure 4 and Figure 5 As shown, since the opening 111 has been blocked by the float 120, the fluid will not flow out through the opening 111; the fluid can fill the entire box, so that when the user uses water, even if the water in the box drops within a certain range, the entire float 120 is still temporarily in a state of blocking the opening 111, which not only ensures that the photovoltaic panel 130 is at a stable current angle, but also protects the clean water in the box from external pollution; when the water volume in the box drops, the water inlet pipe network 200 replenishes the box in time;

[0055] like Figure 6As shown, when encountering extreme weather or emergency situations, the photovoltaic panels 130 need to be folded up, and the water tank 110 needs to be drained through the drainage network 300. The fluid in the water tank 110 will continue to drop, and the float 120 will drop with the drop of the fluid. The above-mentioned friction force disappears, and the angle adjustment rope 140 is also in a relaxed state. The photovoltaic panels 130 in a free state can be flatly attached to the top of the water tank 110, and then the angle adjustment rope 140 is tightened. The photovoltaic panels 130 will be stably positioned at the current position, and a layer of canvas can be laid on all the photovoltaic panels 130 to provide better protection.

[0056] Below, the beneficial effects of the above photovoltaic power generation system are described:

[0057] 1. Use the water storage tank 110 to replace the traditional column pier. The construction workers do not need to carry the cement mortar to a high place. They can directly use the existing pipes to inject water into the tank, which is very time-saving and labor-saving.

[0058] 2. Several water storage tanks 110 are laid on the floor, which is equivalent to a small water tower, which not only effectively solves the water supply and demand problem of users, but also has a heat insulation effect;

[0059] 3. A plurality of photovoltaic power generation units 100 are arranged closely in a rectangular array, which is similar to forming a large stable base with very good wind resistance. However, each photovoltaic panel 130 is independent of each other, and a gap is formed between the photovoltaic panels 130. The windward area of ​​a single photovoltaic panel 130 is small, and the impact of wind is small. When encountering strong winds, the strong wind can pass through the gap without blowing away the connected photovoltaic panels 130.

[0060] 4. The angles of each photovoltaic panel 130 are independently adjustable, which can better adapt to installation scenarios in different environments, thereby maximizing photovoltaic power generation efficiency;

[0061] 5. The fluid can fill the entire box, so that when the user uses water, even if the water in the box drops within a certain range, the entire float 120 is still temporarily in a state of blocking the opening 111, which not only ensures that the photovoltaic panel 130 is at a stable current angle, but also protects the clean water in the box from external pollution;

[0062] 6. Drain the water tank 110 through the drainage pipe network 300, the fluid in the water tank 110 will continue to drop, the photovoltaic panel 130 in a free state can be flatly attached to the top of the water tank 110, and then the angle adjustment rope 140 is tightened, the photovoltaic panel 130 will be stably positioned at the current position, so as to better cope with extreme weather or emergency situations; the water in the water tank does not need to be completely drained, it only needs to meet the conditions for the photovoltaic panel 130 to be retracted, and a certain amount of water is left in the water tank, which can play a better wind resistance effect;

[0063] 7. The angle adjustment rope 140 can not only adjust the angle of the photovoltaic panel 130, but also after the angle adjustment of the photovoltaic panel 130 is completed, the angle adjustment rope 140 is tightened, and the photovoltaic panel 130 is restricted by the angle adjustment rope 140 and becomes more stable.

[0064] In the present invention, a sealing ring 113 (such as Figure 4 and Figure 5 As shown in the figure, the spherical surface of the float 120 abuts against or separates from the sealing ring 113, and the spherical surface of the float 120 abuts against the sealing ring 113 to generate friction and seal the opening 111. By providing the sealing ring 113, on the one hand, the airtightness of the box is ensured to prevent water pollution, and on the other hand, the friction between the float 120 and the sealing ring 113 is increased, thereby making the photovoltaic panel 130 more stable. In this embodiment, the float 120 is made of rubber, which can further increase the friction of the contact.

[0065] In the present invention, the number of angle adjustment ropes 140 is four, the photovoltaic panel 130 is a square plate structure, and the four corners of the photovoltaic panel 130 are fastened to the top of the water storage tank 110 through four angle adjustment ropes 140 respectively, and a locking ring 141 (such as Figure 8 The angle adjustment rope 140 can not only adjust the angle of the photovoltaic panel 130, but also after the angle adjustment of the photovoltaic panel 130 is completed, the angle adjustment rope 140 is tightened, and the photovoltaic panel 130 is restricted by the angle adjustment rope 140 and becomes more stable. In this embodiment, the angle adjustment rope 140 is a steel wire rope, which has a longer service life and higher strength.

[0066] like Figure 4 , Figure 5 and Figure 6As shown, in the present invention, a water inlet hole 114 and an overflow hole 115 are provided on the top of the water tank 110; in each row of two adjacent water tanks 110, the overflow hole 115 of one water tank 110 is connected to the water inlet hole 114 of the other water tank 110; and the water inlet pipe network 200 is connected to the water inlet hole 114 of one of the water tanks 110 in each row. In this way, the water inlet pipe network 200 injects water into the water inlet hole 114 of the water tank 110 at the front end of each row. Since the water tanks 110 in each row overlap and penetrate each other, the fluid will flow through each water tank 110 in turn until all the water tanks 110 in each row are filled with a specified amount of fluid (such as Figure 7 shown).

[0067] like Figure 2 As shown, in the present invention, the drainage network 300 has a plurality of longitudinal drainage branch pipes 310 and a transverse drainage main pipe 320, and the plurality of longitudinal drainage branch pipes 310 are respectively connected to the transverse drainage main pipe 320; each longitudinal drainage branch pipe 310 is provided with a plurality of drainage interfaces 311, and the drainage holes 112 of the water storage tank 110 are plugged into the corresponding drainage interfaces 311. When draining water, a water pump can be used to connect to the port of the transverse drainage main pipe 320, so as to achieve rapid drainage. In the present invention, an avoidance groove 116 (such as a groove 116) is provided at the bottom of the water storage tank 110 for the longitudinal drainage branch pipes 310 to pass through. Figure 3 As shown), the water tank 110 is made flatter during the laying process.

[0068] The present invention also discloses a construction process method of a photovoltaic power generation system, which is implemented based on the above photovoltaic power generation system and includes the following steps:

[0069] Install the drainage network and lay it on the ground;

[0070] Install photovoltaic power generation units, arrange several photovoltaic power generation units closely in a rectangular formation, connect the drainage holes at the bottom of the water storage tanks to the drainage network, and overlap and penetrate each other in each row of water storage tanks;

[0071] Install a water inlet network, which is used to inject fluid into each row of water storage tanks;

[0072] The fluid is injected into each row of water tanks through the water inlet network. The fluid in the water tank rises, and the float blocks the opening due to the buoyancy of the fluid. Friction is generated between the spherical surface of the float and the opening, and the photovoltaic panel is fixed at the current angle, and the angle adjustment rope is tightened. Alternatively, the fluid in the water tank is discharged through the drainage network, and the fluid in the water tank drops. The float drops with the fluid, and the photovoltaic panel fits onto the top of the water tank, and the angle adjustment rope is tightened.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
