[0001] The utility model relates to the technical field of roof waterproofing, in particular to a solar photovoltaic roof waterproofing structure. Background Art

[0002] Solar photovoltaic power generation currently occupies an important position in the world's energy consumption. It will not only replace some conventional energy, but will also become the main body of the world's energy supply. In view of the current development trend of photovoltaic systems attached to buildings in my country, roofs, as a location with good sunlight, provide an excellent location for photovoltaic power generation.

[0003] A photovoltaic engineering roof waterproof structure is disclosed in a Chinese utility model patent with announcement number CN220486932U, which relates to the field of photovoltaic roof technology and includes a main device, which includes a loading unit, a waterproof unit and a drainage unit. The loading unit includes a first cover plate, a fixed block, a second cover plate and a fixed rib, the waterproof unit includes a filter hole, a first filter plate and a second filter plate, and the drainage unit includes a first drain port, a second drain port, a second water storage tank and a first water storage tank. The first cover plate is located on the upper surface of the first filter plate, the second cover plate is located on the upper surface of the second filter plate, and the second filter plate is located on one side of the first filter plate.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device collects rainwater passing through the first filter plate and the second filter plate through the first water storage tank and the second water storage tank, and discharges the accumulated water through the first drain port and the second drain port when the accumulated water is full. Such a setting may easily lead to the inability to completely discharge the accumulated water in the first water storage tank and the second water storage tank, and further easily lead to the continuous accumulation of sewage affecting the service life of the first water storage tank and the second water storage tank. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a solar photovoltaic roof waterproof structure.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a solar photovoltaic roof waterproof structure, comprising a first filter plate, a second filter plate and a sealing plate installed together on the first filter plate and the second filter plate, the bottom surfaces of the first filter plate and the second filter plate are jointly installed with a mounting plate, the upper surface of the mounting plate is provided with a connecting groove, the bottom surface of the mounting plate is connected with a plurality of water storage tanks for storing water flow, the upper surfaces of the plurality of water storage tanks are connected with water inlet pipes, the upper ends of the water inlet pipes extend into the connecting grooves, a common water collecting bucket is provided on the side wall of the water storage tank, the end of the common water collecting bucket is connected with a drain pipe, the side wall of the water storage tank is provided with an installation groove, and the water storage tank is provided with a closing component for closing the water storage tank.

[0007] By adopting the above technical solution, when rain falls on the roof of the photovoltaic project, the rain directly moves downward through the first filter plate and the second filter plate, thereby reducing the probability of the photovoltaic project roof being damp, and then multiple water storage tanks are used to collect rainwater. Subsequently, when the water flow in the water storage tank is almost full, the sealing component automatically opens, and then the water flow in the water storage tank moves to the outside of the water storage tank through the gap between the baffle and the inner bottom wall of the water storage tank. When the rain is small, the water flow in the water storage tank cannot push open the baffle, and the water flow in the water storage tank can slowly move to the outside of the water storage tank through the gap between the baffle and the inner bottom wall of the water storage tank, thereby reducing the probability of water accumulation in the water storage tank.

[0008] Furthermore, an annular plate for improving the stability of the first filter plate is provided on the upper surface of the mounting plate.

[0009] Furthermore, the sealing component includes a baffle rotatably arranged on the upper end of the inner wall of the accommodating groove, a first magnet block embedded in the bottom surface of the baffle, and a second magnet block embedded in the bottom wall of the water storage tank.

[0010] By adopting the above technical solution, when rainwater moves into the water storage tank, the force of the accumulated water on the baffle gradually increases. Subsequently, when the water flow in the water storage tank is almost full, the force of the accumulated water on the baffle is greater than the rotation resistance of the baffle, and the baffle rotates upward under the action of the accumulated water, so that the water flows through the gap between the baffle and the bottom wall of the water storage tank to the outside of the water storage tank. Furthermore, when the water flow is almost completely discharged, the baffle is reset under the action of gravity, so that the first magnet block and the second magnet block are attracted to each other, so that the baffle remains stable again.

[0011] Furthermore, a silicone sheet is provided on the bottom surface of the baffle for increasing the rotation resistance of the baffle.

[0012] Furthermore, a plurality of drainage holes are formed through the side wall of the silicone sheet.

[0013] By adopting the above technical solution, when the rain is small, the water flow in the water storage tank cannot push open the baffle, and the water flow in the water storage tank can slowly move to the outside of the water storage tank through multiple drainage holes, thereby reducing the probability of water accumulation in the water storage tank, which is beneficial to extend the service life of the water storage tank.

[0014] Furthermore, a third magnet block is arranged at the lower end of the side wall of the baffle, an inclined plate is arranged on the side wall of the water storage box, and an electromagnet is arranged on the side wall of the inclined plate close to the third magnet block.

[0015] By adopting the above technical solution, due to the uncertain rain time, sometimes there is a lot of water remaining in the water storage tank, but the water flow cannot push open the baffle, and it takes a long time for the water flow to move out of the water storage tank through the drainage hole. At this time, the staff can energize the electromagnet, which can make the electromagnet adsorb the third magnet block, and then make the baffle rotate upward under the action of the third magnet block, so that the water flow in the water storage tank moves out of the water storage tank.

[0016] Furthermore, an inclined surface sloping downward toward the baffle is provided on the inner bottom wall of the water storage tank.

[0017] By adopting the above technical solution, the probability of the water in the water storage tank slowly moving to the outside of the water storage tank through the drainage hole is increased, thereby improving the user experience of the device.

[0018] Furthermore, a limiting plate for blocking the baffle is arranged on the inner top wall of the water storage tank.

[0019] By adopting the above technical solution, when the staff actively opens the baffle, the staff can change the direction of the current flowing to the electromagnet, thereby reversing the magnetic poles of the electromagnet, so that the electromagnet repels the third magnet block, and then the baffle is quickly reset and pressed against the limit plate, thereby improving the staff's user experience.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, when rain falls on the roof of the photovoltaic project, the rain directly moves downward through the first filter plate and the second filter plate, thereby reducing the probability of the photovoltaic project roof getting damp, and allowing multiple water tanks to collect rainwater. Subsequently, when the water flow in the water tank is almost full, the sealing component automatically opens, allowing the water flow in the water tank to move to the outside of the water tank through the gap between the baffle and the bottom wall of the water tank. When the rain is small, the water flow in the water tank cannot push open the baffle, and the water flow in the water tank can slowly move to the outside of the water tank through the gap between the baffle and the bottom wall of the water tank, thereby reducing the probability of water accumulation in the water tank;

[0022] 2. In the present application, when rainwater moves into the water storage tank, the force of the accumulated water on the baffle gradually increases. Then, when the water flow in the water storage tank is almost full, the force of the accumulated water on the baffle is greater than the rotation resistance of the baffle, and the baffle rotates upward under the action of the accumulated water, so that the water flows through the gap between the baffle and the bottom wall of the water storage tank to the outside of the water storage tank. Furthermore, when the water flow is almost completely discharged, the baffle is reset under the action of gravity, so that the first magnetic block and the second magnetic block are attracted to each other, so that the baffle remains stable again;

[0023] 3. In this application, due to the uncertain rain time, sometimes there is a lot of water remaining in the water tank, but the water cannot push the baffle open, and it takes a long time for the water to move out of the water tank through the drainage hole. At this time, the staff can energize the electromagnet, which can make the electromagnet adsorb the third magnet block, and then make the baffle rotate upward under the action of the third magnet block, so that the water in the water tank moves out of the water tank.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0031] like Figure 1-5As shown, the embodiment of the present application discloses a solar photovoltaic roof waterproof structure, including a first filter plate 1, a second filter plate 11, a cover plate 2, a mounting plate 21, a water storage tank 31, a water inlet pipe 4, a water collecting bucket 41, a drain pipe 5, a closing assembly 6, an annular plate 7, a silicone sheet 71, a third magnet block 81, an inclined plate 82, an electromagnet 83 and a limit plate 9. The cover plate 2 is a plate-like structure, and the cover plate 2 is installed on the first filter plate 1 and the second filter plate 11. The mounting plate 21 is a plate-like structure, and the mounting plate 21 is installed on the bottom surface of the first filter plate 1 and the second filter plate 11. A connecting groove 3 is provided on the upper surface of the mounting plate 21, and the water storage tank 31 is a rectangular parallelepiped structure with a hollow interior. The water storage tank 31 is provided with a plurality of and connected to the bottom surface of the mounting plate 21 for storing water flow. The water inlet pipe 4 is a circular tubular structure, and a plurality of water inlet pipes 4 are provided and sequentially connected to the upper surfaces of a plurality of water storage boxes 31, and the upper end of the water inlet pipe 4 extends into the connecting groove 3. The common water collecting bucket 41 is arranged on the side wall of the water storage box 31, and the drain pipe 5 is a circular tubular structure, and the ends of the drain pipe 5 and the common water collecting bucket 41 are connected to each other.

[0032] The annular plate 7 is a plate-shaped structure with a square ring-shaped cross section. The annular plate 7 is arranged on the upper surface of the mounting plate 21 to improve the stability of the first filter plate 1 .

[0033] A placement groove 51 is provided on the side wall of the water storage tank 31. The closing component 6 is arranged on the water storage tank 31 for closing the water storage tank 31. The closing component 6 includes a baffle 61, a first magnet block 62 and a second magnet block 63. The baffle 61 is a rectangular plate-shaped structure, and the baffle 61 is rotatably arranged on the upper end of the inner wall of the placement groove 51. The first magnet block 62 is a block-shaped structure, and the first magnet block 62 is embedded in the bottom surface of the baffle 61. The second magnet block 63 is a block-shaped structure, and the second magnet block 63 is embedded in the inner bottom wall of the water storage tank 31.

[0034] When rainwater moves into the water storage tank 31, the force of the accumulated water on the baffle 61 gradually increases. Subsequently, when the water flow in the water storage tank 31 is almost full, the force of the accumulated water on the baffle 61 is greater than the rotation resistance of the baffle 61, so that the baffle 61 rotates upward under the action of the accumulated water, so that the water flows through the gap between the baffle 61 and the bottom wall of the water storage tank 31 and moves to the outside of the water storage tank 31. Further, when the water flow is almost completely discharged, the baffle 61 is reset under the action of gravity, so that the first magnet block and the second magnet block 63 are attracted to each other, so that the baffle 61 remains stable again.

[0035] In order to extend the service life of the water storage tank 31, a silicone sheet 71 is provided on the bottom surface of the baffle 61 to increase the rotation resistance of the baffle 61, and a plurality of drainage holes 8 are formed through the side wall of the silicone sheet 71. When the rain is small, the water flow in the water storage tank 31 cannot push the baffle 61 away, and the water flow in the water storage tank 31 can slowly move to the outside of the water storage tank 31 through the plurality of drainage holes 8, thereby reducing the probability of water accumulation in the water storage tank 31, which is conducive to extending the service life of the water storage tank 31.

[0036] The third magnet block 81 is a block structure, and is disposed at the lower end of the side wall of the baffle 61. The inclined plate 82 is a plate structure with a parallelogram cross section, and is disposed on the side wall of the water storage tank 31, and the electromagnet 83 is disposed on the side wall of the inclined plate 82 close to the third magnet block 81.

[0037] Since the raining time is uncertain, sometimes there is a lot of water remaining in the water storage tank 31, but the water cannot push the baffle 61 open, and it takes a long time for the water to move out of the water storage tank 31 through the drainage hole 8. At this time, the staff can energize the electromagnet 83, so that the electromagnet 83 can adsorb the third magnet block 81, and then the baffle 61 can rotate upward under the action of the third magnet block 81, so that the water in the water storage tank 31 can move out of the water storage tank 31.

[0038] In order to increase the probability that the water in the water storage box 31 slowly moves to the outside of the water storage box 31 through the drainage hole 8, thereby improving the user experience of the device, an inclined surface inclined downward toward the baffle 61 is provided on the inner bottom wall of the water storage box 31.

[0039] The limit plate 9 is a rectangular plate-shaped structure, which is arranged on the inner top wall of the water storage tank 31 and is used to block the baffle 61. When the staff actively opens the baffle 61, the staff can change the direction of the current flowing to the electromagnet 83, thereby reversing the magnetic pole of the electromagnet 83, so that the electromagnet 83 repels the third magnet block 81, and then the baffle 61 is quickly reset and pressed against the limit plate 9, thereby improving the staff's use experience.

[0040] The use principle of a solar photovoltaic roof waterproof structure in this embodiment is as follows: when rain falls on the roof of the photovoltaic project, the rain moves downward directly through the first filter plate 1 and the second filter plate 11, thereby reducing the probability of the photovoltaic project roof being damp, and then multiple water storage tanks 31 collect rainwater. Subsequently, when the water flow in the water storage tank 31 is almost full, the closing component 6 automatically opens, and then the water flow in the water storage tank 31 moves to the outside of the water storage tank 31 through the gap between the baffle 61 and the inner bottom wall of the water storage tank 31. When the rainwater is small, the water flow in the water storage tank 31 cannot push the baffle 61 away, and the water flow in the water storage tank 31 can slowly move to the outside of the water storage tank 31 through the gap between the baffle 61 and the inner bottom wall of the water storage tank 31, thereby reducing the probability of water accumulation in the water storage tank 31.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
