Main water tank of photovoltaic power station

Abstract

The invention discloses a main water tank of a photovoltaic power station. A main water tank belongs to one of components used in a waterproof photovoltaic power station. The main water tank is structurally composed of a fixed wall, a water tank top, a tank bottom with a groove, a reinforcing wall, a left small tank wall, a right small tank wall, a right large tank wall and a left large tank wall. After being used in a waterproof photovoltaic power station, the main water tank has the following three advantages: 1, when the photovoltaic panel is fixed in the main water tank, a constructor only needs to fix the photovoltaic panel below the photovoltaic panel, so that the construction is relatively safe; 2, a user does not need to tread on the photovoltaic panel for locking during construction, so that the damage of treading to the photovoltaic panel is reduced; and 3, the photovoltaic panel can be fixed only by locking a tail drill screw without a pressing block corner connector, so that the pressing block corner connector cost is avoided, and the total cost of a photovoltaic power station is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of components used in a waterproof photovoltaic power station constructed by using photovoltaic panels (solar panels) for power generation, specifically a main water tank used in the waterproof photovoltaic power station, referred to as a photovoltaic main water tank. Background Art

[0002] Now the country is vigorously developing clean energy construction and using solar energy to build photovoltaic power stations. There are two categories. One is to build photovoltaic power stations by laying photovoltaic panels in deserts, barren mountains, water surfaces, plains, and factory roofs. The space below this type of photovoltaic power station does not need to be waterproof, and there is no need for water tanks between each photovoltaic panel. When it rains, water will leak from all sides of the photovoltaic panels to the bottom. This is collectively referred to as a non-waterproof power station. The other is to build photovoltaic power stations in rural yards or on rooftops. This type of photovoltaic power station is at a certain height from the ground or roof, and the space below can be used, so Photovoltaic power stations need to prevent water from leaking underneath, so each photovoltaic panel needs to be installed on the main water tank and the auxiliary water tank (the main water tank and the auxiliary water tank are mostly made of aluminum or zinc-aluminum-magnesium. The main water tank has different structural styles, mainly W-type; the auxiliary water tank is mostly universal, mainly U-shaped, and can be used with various main water tanks. The main water tank and the auxiliary water tank are connected to form a grid water tank network). When it rains, rainwater around the photovoltaic panels will flow into the main water tank and the auxiliary water tank, and then be discharged to the designated location. There is no water leakage under the photovoltaic panels. This type of photovoltaic power station is collectively called a waterproof power station. The photovoltaic panels in the waterproof power station are locked to the main water tank, with a spacing of about 60 cm. The photovoltaic panels are locked to the main water tank from the top or bottom by the pressing block angle code and screws. For example: CN219458943U, CN218387333U, CN219458943U, CN218374799U, CN114856093A, CN216721229U, CN211606472U. The main water tank structure in these 7 patent applications requires the pressing block angle code to fix the solar panel to the water tank. The accessories are many and the manufacturing cost is high. The construction workers who lock from the top will step on the photovoltaic panel, which is easy to damage the photovoltaic panel and the construction is also dangerous. Summary of the invention

[0003] In order to overcome the high investment cost and installation danger of the existing main water tank, which needs to use the pressing block angle code for locking, the present invention provides a main water tank composed of a fixed wall, a water tank top, a grooved bottom, a reinforcement wall, a left small tank wall, a right small tank wall, a right large tank wall and a left large tank wall.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a main water tank of a photovoltaic power station, including a large water tank composed of a tank bottom with a groove, a right large tank wall, and a left large tank wall, which is mainly used to transmit water transported by a secondary water tank; a small water tank composed of a tank top, a left small tank wall, and a right small tank wall, which is mainly used to transmit a small amount of water flowing out of the side of a photovoltaic panel; a T-shaped groove is provided in the middle of the tank bottom with a groove, which is used to fix it to a square tube bracket of a photovoltaic power station with a T-shaped screw, and a fixed wall is provided in the middle of the tank top, which is mainly used to allow the tail drill screw to lock the photovoltaic panel to the fixed wall.

[0005] The beneficial effects of the present invention are as follows: the main water tank of the photovoltaic power station of the present invention has a simple structure and low cost. The photovoltaic panel can be locked and fixed to the main water tank by using tail drill screws, and there is no need to use angle code blocks for fixing. The photovoltaic panel can be locked to the main water tank by using tail drill screws under the photovoltaic panel, which reduces the damage to the photovoltaic panel and does not require the use of pressure blocks and angle codes, thereby reducing the material cost (the photovoltaic panel is sealed with glass to generate electricity, and the overall thickness after glass sealing is about 7 mm. It is fixed with an aluminum alloy frame on all sides, and the frame height is about 35 mm; there are no wires, lines or other equipment in the aluminum alloy frame of the photovoltaic panel, which is provided to fix the stability and firmness of the entire solar panel. Using tail drill screws to pass through the frame to fix it to the water tank will not destroy the firmness and stability of the solar panel). BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be described below in conjunction with the accompanying drawings. Figure 1 A photovoltaic main water tank in the embodiment 1 shown includes: a fixed wall 1, a tank top 2, a tank bottom 3 with grooves, a reinforcing wall 4, a left small tank wall 5, a right small tank wall 6, a right large tank wall 7, and a left large tank wall 8. The tank bottom 3 with grooves, the right large tank wall 7, and the left large tank wall 8 form a large tank mainly used to transmit water transported by the U-shaped auxiliary tank, which is referred to as the lower tank here; the tank top 2, the left small tank wall 5, and the right small tank wall 6 form a small tank mainly used to transmit a small amount of water flowing out of the side of the photovoltaic panel, which is referred to as the upper tank here (because the entire photovoltaic power station is normally designed with a slope for drainage, the gap after the photovoltaic panel is fixed on the main tank is very small, and almost no rainwater will flow here, and the drainage pressure here is small); the entire main tank structure is composed of an upper tank and a lower tank to form a double-layer main tank; the middle of the tank bottom 3 with grooves is provided with a T-shaped groove for fixing to the square tube bracket of the photovoltaic power station with a T-shaped screw.

[0017] like Figure 2 The figure shows a side view of the present embodiment (the photovoltaic main water tank of the present invention is an integral long strip profile made of metal materials such as aluminum alloy). According to the required positions of photovoltaic panels of different lengths, a small groove wall opening 9 is cut out on the right small groove wall 6 to place the photovoltaic panel frame, and a large groove opening 10 is cut out on the right large groove wall 7 to insert the U-shaped auxiliary water tank; openings required for installing photovoltaic panels and inserting U-shaped auxiliary water tanks are cut out on the small groove walls and large groove walls on each side of the main water tank.

[0018] like Figure 3 The figure shows a cross-sectional view of the photovoltaic panel installed in this embodiment (for the convenience of demonstration, only the photovoltaic panel is shown). Figure 1 Half, which does not affect the description of the structure and the device), two photovoltaic panels are installed on both sides of the main water tank, the photovoltaic panel frame 11 and the photovoltaic panel frame 13 are two different photovoltaic panel frames on both sides of the main water tank, and the photovoltaic panels on the left and right sides of the main water tank are directly locked to the fixed wall 1 through the tail drill screws 12.

[0019] like Figure 4 In the embodiment shown, the comparison Figure 1The illustrated embodiment lacks the reinforcing wall 4, except that it is less firm, which does not affect the main structural features of the technical solution of the present invention. It still has a groove bottom 3 with a groove, a right large groove wall 7, and a left large groove wall 8 to form a large water trough mainly used to transmit water transported from the auxiliary water trough, which is referred to as the lower trough here; the trough top 2, the left small groove wall 5, and the right small groove wall 6 to form a small water trough mainly used to transmit a small amount of water flowing out of the side of the photovoltaic panel, which is referred to as the upper trough here; the entire main water trough structure is composed of an upper trough and a lower trough to form a double-layer main water trough.

[0020] like Figure 5 In the embodiment shown, the comparison Figure 1 The illustrated embodiment has additional fixed bottom edges 17 and 18 for reinforcing and locking the water tank to the bracket using tail drill screws, which does not affect the main structural features of the technical solution of the present invention. There is still a grooved bottom 3, a right large groove wall 7, and a left large groove wall 8 to form a large water tank mainly used to transmit water transported from the auxiliary water tank, which is referred to as the lower groove here; the groove top 2, the left small groove wall 5, and the right small groove wall 6 form a small water tank mainly used to transmit a small amount of water flowing out from the side of the photovoltaic panel, which is referred to as the upper groove here; the entire main water tank structure consists of an upper groove and a lower groove to form a double-layer main water tank.

[0021] like Figure 6 In the embodiment shown, the comparison Figure 1 The embodiment shown has two reinforcing walls 14 and 15, which are more solid and do not affect the main structural features of the technical solution of the present invention. The groove bottom 3, right large groove wall 7, and left large groove wall 8 form a large water tank mainly used to transmit water transported from the auxiliary water tank, which is referred to as the lower groove here; the groove top 2, left small groove wall 5, and right small groove wall 6 form a small water tank mainly used to transmit a small amount of water flowing out of the side of the photovoltaic panel, which is referred to as the upper groove here; the entire main water tank structure consists of an upper groove and a lower groove to form a double-layer main water tank.

[0022] like Figure 7 In the embodiment shown, the comparison Figure 1 The multi-groove bottom 16 of the shown embodiment can select 1-3 T-type screws to reinforce the water tank without affecting the main structural features of the technical solution of the present invention. The multi-groove bottom 16, the right large groove wall 7, and the left large groove wall 8 form a large water tank mainly used to transmit water transported from the auxiliary water tank, which is referred to as the lower groove here; the groove top 2, the left small groove wall 5, and the right small groove wall 6 form a small water tank mainly used to transmit a small amount of water flowing out of the side of the photovoltaic panel, which is referred to as the upper groove here; the entire main water tank structure consists of an upper groove and a lower groove to form a double-layer main water tank.

[0023] like Figure 8 In the embodiment shown, the comparison Figure 1 The embodiment shown has the sink section narrowed by half. Figure 1In the embodiment shown, photovoltaic panels can be installed on both sides of the fixed wall 1, but the main water tank at the edge of the entire square photovoltaic power station only needs to be equipped with photovoltaic panels on one side, and the other side is the outer edge of the photovoltaic power station; Figure 8 In the embodiment shown, only one side of the fixed wall 1 can be installed with a photovoltaic panel, which not only reduces the production cost but also does not affect the main structural features of the technical solution of the present invention. There is still a groove bottom 3 with a groove, a right large groove wall 7, and a left large groove wall 8 to form a large water trough mainly used to transmit water transported from the auxiliary water trough, which is referred to as the lower trough here; the trough top 2, the fixed wall 1, and the right small groove wall 6 form a small water trough mainly used to transmit a small amount of water flowing out of the side of the photovoltaic panel, which is referred to as the upper trough here; the entire main water trough structure is composed of an upper trough and a lower trough to form a double-layer main water trough.
