Detailed Implementation
[0018] See Figure 1 This utility model discloses a rainwater storage device, comprising a water storage module 1, an inlet pool 2, an inlet pipe 3, a supply pipe 5, a drainage pump 6, a rainwater well 7, a flushing pipe 8, and a control box 9. The water storage module 1 has an inlet pool 2 on its side, and an inlet pipe 3 is provided on the inlet pool 2 to inject rainwater into it. The inlet pool 2 and the water storage module 1 are connected by the supply pipe 5. The water storage module 1 has a drainage pump 6 on its upper part, and the outlet pipe of the drainage pump 6 is connected to the rainwater well 7 and the ground. The water storage module 1 has a flushing pipe 8 for flushing it. The control box 9 is connected to the drainage pump 6 by a wire. Rainwater enters the inlet pool 2 through the inlet pipe 3 and then enters the water storage module 1 through the supply pipe 5. The drainage pump 6 can discharge clean rainwater to water plants and discharge dirty water into the sewer, thus keeping the water in the water storage module 1 clean.
[0019] The water storage module 1 is made of polypropylene and has a hollowed-out water storage space. This hollowed-out space allows the water storage module 1 to store water and also increases its strength, enabling it to bear a certain weight. Figure 1 As shown, it also includes an overflow pipe 4, which is installed above the inlet pool 2. When a large amount of rainwater enters the inlet pool 2 and the water level in the inlet pool 2 reaches a certain height, the rainwater flows into the sewer through the overflow pipe 4, which can prevent excessive water accumulation on the road due to the inability to collect rainwater quickly. Figure 3 and Figure 4 As shown, the inlet pipe 3 includes a filter pipe body 31, a rainwater collecting pipe 32, and a filter plug 33. The filter pipe body 31 is vertically arranged, and the filter plug 33 is installed inside the filter pipe body 31 by being pulled up and down. Above the filter plug 33 on the filter pipe body 31, a rainwater collecting pipe 32 is provided to guide the collected rainwater into the filter pipe body 31. The rainwater enters the filter pipe body 31 through the rainwater collecting pipe 32 and is filtered by the filter plug 33 in the filter pipe body 31. The filter plug 33 can be pulled out from the top of the filter pipe body 31 for replacement and cleaning, making installation and disassembly simple and convenient. Figure 5As shown, the filter plug 33 includes a pull rod 331, a pull ring 332, a filter cup 333, and a sealing ring 334. The pull ring 332 is fixed at the upper end of the pull rod 331. At least two filter cups 333 are provided on the pull rod 331. A sealing ring 334 is provided between the upper end of the filter cup 333 and the filter tube 31. A drainage gap is provided between the lower part of the filter cup 333 and the filter tube 31. Rainwater passes through the filter cup 333, and the filtered rainwater flows out from around the lower part of the filter cup 333. Because a sealing ring 334 is provided between the upper end of the filter cup 333 and the filter tube 31, rainwater cannot flow in from the gap between the filter cup 333 and the upper side of the filter tube 31.
[0020] like Figure 2 As shown, the drainage pump 6 includes a pump body 61, a main drainage pipe 62, a clean water drainage pipe 63, a sewage drainage pipe 64, a main inlet pipe 65, a sewage inlet pipe 66, a clean water inlet pipe 67, and a buoyancy filter ball 68. The main drainage pipe 62 is installed at the outlet of the pump body 61, and the clean water drainage pipe 63 and sewage drainage pipe 64 are connected to the main drainage pipe 62. Solenoid valves are installed on the clean water drainage pipe 63 and sewage drainage pipe 64 respectively. The main inlet pipe 65 is installed at the inlet of the pump body 61, and the sewage inlet pipe 66 and clean water inlet pipe 67 are connected to the main inlet pipe 65. The inlet end of the sewage inlet pipe 66 is located at the bottom of the water storage module 1. The inlet end of the clean water inlet pipe 67 is equipped with a filter ball 68. The inlet of water 7 is located at the buoyancy filter ball 68 at the water surface position inside the water storage module 1. The buoyancy filter ball 68 can make the height of the inlet end of the clean water inlet pipe 67 change with the water surface height, so as to keep the water drawn from the liquid surface position relatively clean. The sewage inlet pipe 66 is located at the bottom of the water and can absorb the sedimented impurities and garbage. During operation, by controlling the solenoid valves on the sewage inlet pipe 66 and the clean water inlet pipe 67 to switch on and off alternately, the water pumped out by the water pump body 61 can be clean water or dirty water. Similarly, by switching the solenoid valves on the clean water drain pipe 63 and the sewage drain pipe 64 on and off alternately, water can be discharged from the clean water drain pipe 63 or the sewage drain pipe 64. The outlet of the clean water drain pipe 63 can be connected to the grass or other places that need plant irrigation, and the sewage drain pipe 64 can be connected to the sewer.
[0021] The working process of this utility model:
[0022] This utility model discloses a rainwater storage device. During operation, the water storage module 1 has a hollowed-out space, allowing it to store water. Rainwater enters the inlet pool 2 through the inlet pipe 3 and then enters the water storage module 1 through the supply pipe 5. A drainage pump 6 discharges clean rainwater to water plants and drains dirty water into the sewer, keeping the water in the storage module 1 clean. When a large amount of rainwater enters the inlet pool 2 and the water level reaches a certain height, the rainwater flows into the sewer through the overflow pipe 4, preventing excessive water accumulation on the road due to slow rainwater collection. The rainwater passes through a filter cup 333, and the filtered rainwater flows out from around the bottom of the filter cup 333. A sealing ring 334 is provided between the upper end of the filter cup 333 and the filter tube body 31. Therefore, rainwater cannot flow in through the gap between the filter cup 333 and the upper side of the filter tube 31; the buoyancy filter ball 68 can make the height of the inlet end of the clean water inlet pipe 67 change with the water level, keeping the water level at a relatively clean position; the sewage inlet pipe 66 is located at the bottom of the water and can absorb sedimented impurities and garbage. During operation, by controlling the solenoid valves on the sewage inlet pipe 66 and the clean water inlet pipe 67 to alternately switch on and off, the water pump body 61 can be pumped out as either clean water or dirty water. Similarly, by alternating the switching on and off of the solenoid valves on the clean water drain pipe 63 and the sewage drain pipe 64, water can be discharged from either the clean water drain pipe 63 or the sewage drain pipe 64. The outlet of the clean water drain pipe 63 can be connected to places that need plant irrigation, such as grasslands, and the sewage drain pipe 64 can be connected to the sewer.
[0023] This utility model discloses a rainwater storage device. By using polypropylene plastic to manufacture the rainwater collection module, it is pollution-free, with no leaching when soaked in water, no odor, high temperature resistance of -30 to 120℃, resistance to strong acids and alkalis, and is unaffected by soil microorganisms, algae, bacteria, asphalt, etc. These excellent properties help improve the quality of stored water and are easy to maintain. The rainwater collection module saves a lot of costs, improves efficiency, is simple to install, has low cost, and short construction period. At the same time, it can ensure that the stored water is pollution-free and can realize the separate discharge of clean water and wastewater.
