Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainwater purification and recycling technology, and in particular to a rainwater purification and recycling device for sponge city construction. Background Technology
[0002] In the construction of sponge cities, rainwater purification and recycling systems are one of the key infrastructure components. These systems aim to collect, purify, store, and reuse rainwater through rational design and technological means. They not only alleviate the burden on urban drainage systems but also improve rainwater utilization efficiency, promoting sustainable urban development.
[0003] Traditional methods for purifying and recycling urban rainwater involve multiple processes, such as collection, coarse filtration, sedimentation, secondary filtration, and disinfection. During the collection and coarse filtration process, larger suspended solids such as leaves, dust, and gravel are removed from the rainwater, which helps reduce the pressure on subsequent purification processes. However, in actual use, it has been found that when larger impurities are intercepted and removed, these impurities will temporarily remain on the surface of the filter screen, affecting the filter screen's water filtration and drainage efficiency. In cases of excessive water flow, it can even lead to blockage. Utility Model Content
[0004] The technical problem to be solved by this utility model is that when larger impurities are intercepted and removed, these impurities will temporarily remain on the surface of the filter screen, which will affect the water filtration and drainage effect of the filter screen, and may even cause blockage when the water flow is too large.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a rainwater purification and recycling device for sponge city construction, including a water tank, a water pump installed on the side of the water tank, and a filter device provided on the surface of the water tank, wherein the filter device removes larger impurities by means of an arc-shaped filter screen and a rotating plate.
[0006] The effect achieved by the above-mentioned components is as follows: when the rainwater is collected in the city using the recycling device, the rainwater first flows on the road surface and falls into the filter device on one side of the underground water tank. Through the processing of the filter device, larger impurities are intercepted and filtered. Then the treated water enters the water tank and is transported by the water pump to the next processing stage.
[0007] Preferably, the filtration device includes a water inlet pipe, which is assembled on the top surface of the water tank. An arc-shaped filter screen is fixedly connected to the inner wall of the water inlet pipe. A rotating rod is installed through the surface of the water tank. Several evenly distributed rotating plates are fixedly connected to the arc surface of the rotating rod. A servo motor is installed on the surface of the water inlet pipe. The output end of the servo motor is fixedly installed to the rotating rod by means of a coupling. A baffle is installed at one side opening of the water inlet pipe by means of bolts.
[0008] The effect achieved by the above components is that the recycling device can better handle the impurities that are intercepted and filtered during use, and is less likely to affect the normal use of the filter screen, thereby ensuring the normal flow and drainage of rainwater and improving the working efficiency and use effect of the device.
[0009] Preferably, the filtration device further includes an auxiliary plate fixedly installed on the inner wall of the water inlet pipe, wherein the auxiliary plate enhances the effect of the arc-shaped filter screen.
[0010] The effect achieved by the above components is as follows: by setting the auxiliary plate, which is inclined in the inner wall of the water inlet pipe, the impurities entering the water inlet pipe can be stably and vertically placed on the arc-shaped filter screen, thereby facilitating the rotation of the rotating plate.
[0011] Preferably, the filtration device further includes an auxiliary block installed on the inner wall of the inlet pipe, wherein the auxiliary block improves the efficiency of impurity and waste collection in the inlet pipe.
[0012] The effect achieved by the above components is as follows: the auxiliary block is designed so that its inner wall size is compatible with the arc-shaped filter screen and the rotating plate. This ensures that the collection of garbage and impurities on the side of the filter screen and the water inlet pipe is relatively separated, which facilitates the rotation of the rotating plate and improves the impurity treatment effect of the filtration device.
[0013] Preferably, a sealing ring is fixedly connected to the four sides of the baffle, wherein the sealing ring ensures the sealing performance of the baffle.
[0014] The effect achieved by the above components is that, through the setting of the rubber sealing ring, when the baffle is installed at the side opening of the water inlet pipe, good sealing performance is ensured, and rainwater leakage is not easy.
[0015] Preferably, the surface of the water inlet pipe is provided with an auxiliary device, wherein the auxiliary device includes an auxiliary frame, a protective net is fixedly connected to the top opening of the auxiliary frame, and a fixing plate is installed on both sides of the surface of the auxiliary frame, wherein the fixing plate is inserted into the fixing frame fixedly connected to the surface of the water inlet pipe, and the fixing plate and the fixing frame are fixedly connected by screws.
[0016] The effect achieved by the above components is as follows: When protecting the opening of the water inlet pipe, the auxiliary frame is first covered on the surface of the water inlet pipe. At this time, the fixing plates fixedly connected to both sides of the auxiliary frame surface will be inserted into the inner wall of the fixing frame fixedly connected to both sides of the water inlet pipe surface. Finally, the screws are threaded through the surface of the fixing frame and connected to the fixing plates, thereby ensuring the position of the auxiliary frame is fixed. When the water inlet pipe collects rainwater, it can intercept impurities to a certain extent, making it less likely for large impurities to enter the water inlet pipe, thus ensuring the normal use of the filtration device.
[0017] Preferably, the auxiliary device further includes a washer fitted onto the surface of the screw, wherein the washer enhances the performance of the screw.
[0018] The effect achieved by the above components is that, by setting the washers, the screws are installed on the surface of the fixed frame, making them fit more stably and less prone to rotation and loosening.
[0019] Preferably, the protective net has a tapered cross-section, and the special cross-section design improves the effectiveness of the protective net.
[0020] The effect achieved by the above components is that, through the special cross-section protective netting, large impurities can quickly slide off the surface of the protective netting, thereby better protecting the opening of the water inlet pipe.
[0021] The beneficial effects of this utility model are:
[0022] The recycling device of this invention can better handle the impurities that are intercepted and filtered during use, and is less likely to affect the normal use of the filter screen, thereby ensuring the normal flow and drainage of rainwater and improving the working efficiency and effectiveness of the device.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Figure 1 and Figure 2 The rainwater purification and recycling device for sponge city construction shown includes a water tank 1, a water pump 4 installed on the side of the water tank 1, a filter device 2 installed on the surface of the water tank 1, wherein the filter device 2 removes larger impurities by means of an arc-shaped filter screen 22 and a rotating plate 25, and an auxiliary device 3 is installed on the surface of the water inlet pipe 21.
[0032] Figure 1 , Figure 2 and Figure 3 The filtration device 2 shown includes an inlet pipe 21, which is mounted on the top surface of the water tank 1. An arc-shaped filter screen 22 is fixedly connected to the inner wall of the inlet pipe 21. A rotating rod 23 is installed through the surface of the water tank 1, and several evenly distributed rotating plates 25 are fixedly connected to the arc surface of the rotating rod 23. A servo motor 24 is installed on the surface of the inlet pipe 21, and the output end of the servo motor 24 is fixedly installed to the rotating rod 23 by means of a coupling. A baffle 26 is installed at one side opening of the inlet pipe 21 by means of bolts 27. When the recycling device is used to collect rainwater in the city, the rainwater first flows on the road surface and falls into the inlet pipe 21 on one side of the underground water tank 1, and then falls onto the arc-shaped filter screen 22 on the inner wall of the inlet pipe 21. At this time, the servo motor at the side of the inlet pipe 21 is activated. The servo motor 24 drives the rotating plate 25 fixedly connected to the mounting rod to rotate. While rotating, the rotating plate 25 contacts and slides against the surface of the arc-shaped filter screen 22, thereby pushing and picking up the impurities and garbage on the surface of the arc-shaped filter screen 22. When it rotates to the other side, the impurities and garbage fall into the inner wall of the side of the water inlet pipe 21. After a certain amount is collected, the operating bolt 27 opens the baffle 26 on the side of the water inlet pipe 21 to remove the impurities and garbage. The treated water then enters the water tank 1 and is transported by the water pump 4 to the next processing stage. At this time, when the recycling device is in use, it can better process the intercepted and filtered impurities, and is less likely to affect the normal use of the filter screen, thereby ensuring the normal flow and drainage of rainwater and improving the working efficiency and use effect of the device.
[0033] Figure 1 , Figure 2 and Figure 3The filter device 2 shown also includes an auxiliary plate 29 fixedly installed on the inner wall of the inlet pipe 21. The auxiliary plate 29 enhances the effectiveness of the arc-shaped filter screen 22. Because the auxiliary plate 29 is inclined within the inner wall of the inlet pipe 21, impurities entering the inlet pipe 21 can stably and vertically fall onto the arc-shaped filter screen 22, facilitating the rotation of the rotating plate 25. The filter device 2 also includes an auxiliary block 210 installed on the inner wall of the inlet pipe 21. The auxiliary block 210 improves the efficiency of impurity and debris collection in the inlet pipe 21. The auxiliary block 210 is designed to be compatible with the inner wall size of the arc-shaped filter screen 22 and the rotating plate 25. This ensures that the collection of debris and impurities on the side of the filter screen and the water inlet pipe 21 is relatively separated, which facilitates the rotation of the rotating plate 25 and improves the impurity treatment effect of the filter device 2. The baffle 26 is fixedly connected with sealing rings 28 on its four sides. The sealing rings 28 ensure the sealing performance of the baffle 26. The rubber sealing rings 28 ensure good sealing when the baffle 26 is installed at the side opening of the water inlet pipe 21, and it is not easy for rainwater to leak.
[0034] Figure 1 , Figure 2 and Figure 4 The auxiliary device 3 shown includes an auxiliary frame 31, a protective net 32 fixedly connected to the top opening of the auxiliary frame 31, and fixing plates 33 installed on both sides of the surface of the auxiliary frame 31. The fixing plates 33 are inserted into the fixing frame 34 fixedly connected to the surface of the water inlet pipe 21. The fixing plates 33 and the fixing frame 34 are connected and fixed by screws 35. When protecting the opening of the water inlet pipe 21, the auxiliary frame 31 is first covered on the surface of the water inlet pipe 21. At this time, the fixing plates 33 fixedly connected to both sides of the surface of the auxiliary frame 31 will be inserted into the inner wall of the fixing frame 34 fixedly connected to both sides of the surface of the water inlet pipe 21. Finally, the screws 35 penetrate the surface of the fixing frame 34 and are threadedly connected to the fixing plates 33, thereby ensuring the fixed position of the auxiliary frame 31. At this time, when the water inlet pipe 21 collects rainwater, it can intercept impurities to a certain extent, making it difficult for large impurities to enter the water inlet pipe 21, thus ensuring the normal use of the filter device 2.
[0035] Figure 1 and Figure 4 The auxiliary device 3 shown also includes a washer 36 fitted onto the surface of the screw 35. The washer 36 enhances the performance of the screw 35. By setting the washer 36, the screw 35 is mounted on the surface of the fixing frame 34, making it more stable and less prone to rotation and loosening. The protective net 32 has a tapered cross-section. The special cross-section design improves the performance of the protective net 32. By setting the special cross-section of the protective net 32, large impurities can quickly slide off the surface of the protective net 32, thereby better protecting the opening of the water inlet pipe 21.
[0036] Working principle: When using the recycling device to collect rainwater in the city, the rainwater first flows on the road surface and falls into the inlet pipe 21 on one side of the underground water tank 1. Then it falls onto the arc-shaped filter screen 22 on the inner wall of the inlet pipe 21. At this time, the servo motor 24 located on the side of the inlet pipe 21 is activated. The servo motor 24 drives the rotating plate 25 fixedly connected to the mounting rod to rotate. As the rotating plate 25 rotates, it contacts and slides against the surface of the arc-shaped filter screen 22, thereby pushing and picking up the impurities and garbage on the surface of the arc-shaped filter screen 22. The water is collected and, as it rotates to the other side, falls into the inner wall of the inlet pipe 21. After a certain amount is collected, the operating bolt 27 opens the baffle 26 on the side of the inlet pipe 21 to remove impurities and waste. The treated water then enters the water tank 1 and is transported by the water pump 4 to the next processing stage. At this time, when the recycling device is in use, it can better treat the intercepted and filtered impurities, and is less likely to affect the normal use of the filter screen, thereby ensuring the normal flow and drainage of rainwater and improving the working efficiency and use effect of the device.
[0037] When protecting the opening of the water inlet pipe 21, firstly, the auxiliary frame 31 is covered on the surface of the water inlet pipe 21. At this time, the fixing plates 33 fixedly connected to both sides of the surface of the auxiliary frame 31 will be inserted into the inner wall of the fixing frame 34 fixedly connected to both sides of the surface of the water inlet pipe 21. Finally, the screws 35 are threaded through the surface of the fixing frame 34 and connected to the fixing plates 33, thereby ensuring that the position of the auxiliary frame 31 is fixed. At this time, when the water inlet pipe 21 collects rainwater, it can intercept impurities to a certain extent, making it difficult for large impurities to enter the water inlet pipe 21, thus ensuring the normal use of the filter device 2.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
