A rainwater harvesting and reuse storage tank for cleaning photovoltaic panels

Abstract

This utility model provides a rainwater collection and reuse storage tank for photovoltaic panel cleaning, relating to the field of water storage tank technology. It includes: a water storage tank body, with a protective filter mechanism at the upper end and a sterilization mechanism at the lower end of the protective filter mechanism. The water storage tank body includes a tank body. The sealing cover of this utility model is slightly heavier than the water collection shell and counterweight, allowing the water collection shell to receive only a small amount of rainwater before the sealing cover can be rotated by a rotating rod, thus automatically opening the sealing cover without manual operation. When the sealing cover is opened to a certain angle, a spring clip at the lower end secures it, allowing rainwater to flow out of the water collection shell. When the weather is sunny, a rainwater sensor receives a signal, causing the electric drive component to operate, relocking the spring clip and releasing the sealing cover. The sterilization mechanism sterilizes the water inside the tank.

Description

Technical Field

[0001] This utility model relates to the field of water storage tank technology, and in particular to a rainwater collection and reuse water storage tank for cleaning photovoltaic panels. Background Technology

[0002] Rainwater harvesting and reuse storage tanks used for cleaning photovoltaic panels are water-saving devices that collect and store natural rainfall for cleaning dust and dirt off the surface of photovoltaic modules. They reduce dependence on tap water and groundwater, thereby lowering operating costs. In large-scale photovoltaic power plants where water resources are scarce or water access is inconvenient, they have significant economic and environmental value.

The front end of the sealing cap 21 is fixedly connected. The lower end of the tank body 11 is connected to the upper end of the support frame 12 by bolt threads. The upper end of the tank body 11 is connected to the lower end of the water collecting hopper 13 by bolt threads. The upper end of the rotating fixing part 23 is fixedly connected to the lower end of the rotating rod 22. The rear end of the fixing slot 24 is fixedly connected to the upper end of the water collecting hopper 13. The lower end of the rotating fixing part 23 is fixedly connected to the upper end of the fixing slot 24 by a tenon connection. The rear end of the fixing bracket 26 is fixedly connected to the lower end of the water collecting hopper 13. The upper end of the fixing bracket 26 is provided with a corresponding slot for the spring buckle 25. The lower end of the fixing bracket 26 is connected to the lower end of the spring buckle 25 by bolt threads. The left end of the spring clip 25 is provided with a corresponding groove for the electric drive component 28. The lower end of the rain sensor 27 is connected to the upper end of the electric drive component 28 by bolt threads. The upper end of the second fixed bracket 281 is connected to the lower end of the electric drive component 28 by bolt threads. The rear end of the water collection housing 221 is connected to the front end of the rotating rod 22 by bolt threads. The lower end of the water collection housing 221 is provided with a corresponding slot for the counterweight 222. The water collection housing 221 and the counterweight 222 are fixed by the slot. The outer side of the first filter plate 29 is connected to the top of the water collection hopper 13 by bolt threads. The outer side of the second filter plate 291 is connected to the bottom of the water collection hopper 13 by bolt threads.

[0021] In this embodiment, the tank body 11 and the support frame 12 are connected by bolts and threads. The support frame 12 provides support for the tank body 11 to prevent it from collapsing. The tank body 11 and the water collection hopper 13 are connected by bolts and threads. The water collection hopper 13 at the upper end of the tank body 11 can collect rainwater more effectively. The sealing cover 21 is fixedly connected to the rotating rod 22, the rotating fixing part 23 is fixedly connected to the rotating rod 22, the fixing slot 24 is fixedly connected to the water collection hopper 13, and the rotating fixing part 23 and the fixing slot 24 are fixedly connected by a tenon. The rotating rod 22 is connected to the water collection shell 221 by bolts and threads. The lower end of the water collection shell 221 is provided with a corresponding configuration block. The water collection housing 221 and the counterweight 222 are fixed by a slot. The first fixed bracket 26 is fixedly connected to the water collection hopper 13. The front end of the first fixed bracket 26 is provided with a slot corresponding to the spring buckle 25. The fixed bracket and the spring buckle 25 are connected by bolt threads. The second fixed bracket 281 is fixedly connected to the water collection hopper 13. The second fixed bracket 281 is connected to the electric transmission component 28 by bolt threads. The electric transmission component 28 is connected to the rain sensor 27 by bolt threads. The lower end of the rotating fixed component 23 is provided with a rectangular protrusion. The left end of the spring buckle 25 is provided with a sliding groove corresponding to the electric transmission component 28. The lower end of the rotating fixed component 23 is provided with a slot corresponding to the spring buckle 25. The sealing cover 21 is slightly heavier than the water collection housing 221 and the counterweight 222. The counterweight 222 at the lower end of the water collection housing 221 allows the housing to collect less rainwater, making its overall weight greater than the sealing cover 21. The water collection housing 221's weight is greater than the sealing cover 21's at its location. The rotating rod 22, connected to the water collection housing 221 and the sealing cover 21, causes the sealing cover 21 to rotate rectangularly via the rotating fixing member 23, thus collecting rainwater and allowing the rainwater inside the water collection housing 221 to flow out. The rotation of the sealing cover 21 triggers the firing device on the spring clip 25 via the rectangular protrusion at the lower end of the rotating fixing member, thus fixing the spring clip 25 and ultimately securing the sealing cover 21. When the rain stops, the rain sensor 27 receives a signal and transmits it to the electric drive component 28, causing the electric drive component 28 to operate. This causes the shaft at its front end to move along the corresponding slide groove, relocking the spring clip 25 and releasing the sealing cover 21. The sealing cover 21 then closes again, protecting the water collection hopper 13 from falling leaves and dead branches that could cause blockages. The water collection hopper 13 is connected to the first filter plate 29 by bolts and threads, and the water collection hopper 13 is also connected to the second filter plate 291 by bolts and threads. The first filter plate 29 performs preliminary filtration of the collected rainwater, preventing impurities from entering the tank 11. The second filter plate 291 further filters the filtered rainwater, reducing the amount of impurities entering. Through the cooperation of these parts, the water storage tank is protected and the rainwater is effectively filtered. Example

[0022] like Figure 1-4 As shown, the sterilization mechanism 3 includes an injection pipe 31, a liquid delivery pipe 32 at the rear end of the injection pipe 31, a liquid storage tank 33 at the lower end of the liquid delivery pipe 32, and a support plate 34 at the lower end of the liquid storage tank 33. The water storage tank body 1 includes a support frame 12. The upper end of the tank body 11 is provided with a slot corresponding to the injection pipe 31. The outer side of the injection pipe 31 is fixedly connected to the upper end of the tank body 11. The rear end of the injection pipe 31 is provided with a slot corresponding to the liquid delivery pipe 32. The rear end of the injection pipe 31 and the front end of the liquid delivery pipe 32 are connected and fixed through the slot. The lower end of the support plate 34 is provided with a slot corresponding to the support frame 12. The lower end of the support plate 34 is connected to the upper end of the support frame 12 by bolt threads. The lower end of the liquid storage tank 33 is connected to the upper end of the support plate 34 by bolt threads. The bottom end of the liquid storage tank 33 is provided with a slot corresponding to the liquid delivery pipe 32. The bottom end of the liquid storage tank 33 is fixedly connected to the liquid delivery pipe 32.

[0023] In this embodiment, the upper end of the tank body 11 is provided with a slot corresponding to the injection pipe 31, and the injection pipe 31 is fixedly connected to the tank body 11. The rear end of the injection pipe 31 is provided with a slot corresponding to the liquid delivery pipe 32, and the injection pipe 31 and the liquid delivery pipe 32 are connected and fixed through the slots. The lower end of the support plate 34 is provided with a slot corresponding to the support frame 12, and the support plate 34 and the support frame 12 are connected by bolt threads. The liquid storage tank 33 is connected to the support plate 34 by bolt threads. The bottom end of the liquid storage tank 33 is provided with a slot corresponding to the liquid delivery pipe 32, and the liquid storage tank 33 is fixedly connected to the liquid delivery pipe 32 for liquid delivery. Pipe 32 is connected to the pump body at the rear end. The disinfectant is drawn by the pump body inside the storage tank 33 and delivered to the injection pipe 31 through the delivery pipe 32. It is then injected into the tank 11 through the injection pipe 31, thereby sterilizing the rainwater collected inside the tank 11 and preventing the proliferation of anaerobic bacteria and algae. This reduces the pollution of the water inside the tank 11 and keeps the water clean, making the cleaning of the photovoltaic panels more thorough. Through the cooperation of the above parts, the sterilization effect of the water inside the tank 11 can be achieved.

[0024] Working principle: like Figure 1-4As shown, the support frame 12 provides support for the tank 11, preventing it from collapsing. The water collection hopper 13 at the top of the tank 11 allows for more effective rainwater collection. The sealing cover 21 is slightly heavier than the water collection shell 221 and the counterweight 222. The counterweight 222 at the bottom of the water collection shell 221 allows it to collect less rainwater, making its overall weight greater than the sealing cover 21. The water collection shell 221 effectively collects rainwater. The weight of the object at its location is greater than that of the sealing cover 21. Therefore, through the rotating rod 22 connected to the water collection housing 221 and the sealing cover 21, the sealing cover 21 is rotated rectangularly via the rotating fixing member 23. This collects rainwater and allows the rainwater inside the water collection housing 221 to flow out. The rotation of the sealing cover 21 causes the rectangular protrusion at the lower end of the rotating fixing member to activate the firing device on the spring clip 25. This causes the spring clip 25 to fix the rotating fixing member, thus securing the sealing cover 21. When the rain stops, the rain sensor 27 receives a signal and transmits it to the electric drive component 28, causing the electric drive component 28 to operate. This causes the shaft at its front end to move along the corresponding slide groove, relocking the spring clip 25 and releasing the sealing cover 21. The sealing cover 21 then closes again, protecting the water collection hopper 13 from falling leaves and dead branches that could cause blockages. The collected rainwater is initially filtered by the first filter plate 29 to prevent impurities from entering the tank 11. The filtered rainwater is then further filtered by the second filter plate 291 to reduce the amount of impurities entering. The disinfectant is drawn by the pump inside the storage tank 33 and delivered to the injection pipe 31 through the delivery pipe 32. The disinfectant is then injected into the tank 11 through the injection pipe 31, thus sterilizing the rainwater collected inside the tank 11 and preventing the proliferation of anaerobic bacteria and algae. This reduces pollution of the water inside the tank 11, keeping the water clean and allowing for more thorough cleaning of the photovoltaic panels.
