[0021] 3. The present application uses a moving component, a cleaning plate and a spring 1 in coordination. When impurities accumulate on the filter and the rainwater cannot be filtered normally, the overall weight of the water collecting box increases and decreases while compressing the spring 1. The length of the rope between the support shaft and the connecting rod becomes shorter, and then the spring 2 drives the cleaning plate to move to clean the filter to facilitate the passage of rainwater. At the same time, the overall weight of the water collecting box is reduced, and the water collecting box and the cleaning plate are reset, which facilitates the subsequent cleaning of the filter.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figure 1-Figure 8 As shown, the present application provides a rainwater recycling device for a sponge city road, including a reservoir 1, a collection box 2 for collecting rainwater is provided on the top of the reservoir 1, the collection box 2 is connected to the reservoir 1 through an inlet pipe 8, a filter screen 3 for blocking is provided inside the collection box 2, a guide pipe 4 for flow is provided on the top of the reservoir 1, and a nozzle 5 is provided on one side of the guide pipe 4; rainwater enters through the protective cover 10 of the collection box 2, and blocks larger impurities in the rainwater, and then is filtered through the filter screen 3 to remove fine debris, and then the filtered rainwater flows into the reservoir 1 through the inlet pipe 8 for storage, and when the water level in the reservoir 1 is too high, the excess rainwater is discharged through the overflow pipe 7. When there are many impurities accumulated on the filter screen 3 and it cannot be cleaned by the cleaning mechanism 11, the filter screen 3 can be taken out for cleaning or replacement.

[0034] The cleaning mechanism 11 is arranged in the collecting box 2 , and is used for cleaning impurities on the filter screen 3 .

[0035] A bearing plate 6 for support is fixedly installed on the top of the water reservoir 1, and an overflow pipe 7 is fixedly connected to one side of the water reservoir 1. The bearing plate 6 can be arranged to close the water reservoir 1, and the parts on the top of the water reservoir 1 can be supported at the same time. The overflow pipe 7 can be arranged to facilitate the connection of the water reservoir 1 with an external pipe connected to the river, so that the water flow inside the water reservoir 1 can be discharged into the river when the amount of rainwater is large, thereby reducing the accumulation of water on urban roads.

[0036] The outer surface of the water inlet pipe 8 is fixedly connected with a fastening ring 9, and the bottom of the fastening ring 9 is fixedly installed with the top of the load-bearing plate 6. Through the setting of the water inlet pipe 8, the rainwater collected by the collection box 2 can be injected into the device, and the setting of the fastening ring 9 can keep the collection box 2 stable when in use, thereby reducing the leakage of rainwater during transportation.

[0037] A protective cover 10 is fixedly mounted on the top of the collection box 2, and an opening 12 is formed through one side of the protective cover 10. The setting of the protective cover 10 can block large debris contained in rainwater and reduce the situation where pedestrians fall into the device when walking. The setting of the opening 12 is conducive to the passage of the rope 1143.

[0038] The top of the guide tube 4 is threadedly connected with an elbow 14, and one side of the elbow 14 is threadedly connected with a universal tube 15. Through the setting of the elbow 14, the water flow can flow in a preset direction, reducing the kinetic energy loss of the water flow during the flow, and the setting of the universal tube 15 can adjust the spraying direction of the water flow as needed to increase the spraying range of the device.

[0039] The outer surface of the guide pipe 4 is fixedly connected with a flange 16, the bottom of the flange 16 is fixedly installed with the top of the bearing plate 6, the bottom of the guide pipe 4 is threadedly connected with a pipe joint 17, and a water pump 18 is installed inside the water reservoir 1. The water pump 18 is electrically connected to an external power supply and controlled by a control program, and the water pump 18 is detachably connected to the pipe joint 17. The setting of the flange 16 can reduce the shaking of the guide pipe 4 when conveying water, and improve the service life of the guide pipe 4. The setting of the pipe joint 17 can facilitate the assembly of the guide pipe 4 and the water pump 18. The setting of the water pump 18 can provide power for the rainwater inside the device, so that it has sufficient pressure to spray out of the device.

[0040] The inner wall of the nozzle 5 is threadedly connected with a pressurized pipe 19, the outer surface of the pressurized pipe 19 is threadedly connected with the inner wall of the universal pipe 15, and the outer surface of the pressurized pipe 19 is clamped with a sealing gasket 20. The setting of the pressurized pipe 19 can reduce the flow diameter of the water flow, thereby further pressurizing the water flow, and the setting of the sealing gasket 20 can reduce the leakage caused by the pressure when the water flow flows. When the stored rainwater needs to be used, the water pump 18 is started, and the rainwater flows into the nozzle 5 through the guide pipe 4, the elbow 14, the universal pipe 15 and the pressurized pipe 19. The nozzle 5 pressurizes the rainwater and sprays it into fine water droplets to cover the road or green belt.

[0041] Embodiment 2

[0042] Based on Example 1, see Figure 5 , Figure 7 and Figure 8shown.

[0043] The inside of the collection box 2 is fixedly connected with a support frame 13 and a support shaft 21, the support shaft 21 is rotatably connected with a guide wheel 1 22, and the outside of the collection box 2 is fixedly connected with a guide wheel 23, and two guide wheels 23 are provided. The setting of the support frame 13 can support the water collection box 112 when the water collection box 112 descends, so as to avoid clamping the rope 1143 during the compression of the spring 111.

[0044] The cleaning mechanism 11 includes a spring 111 fixedly connected to the inside of the collection box 2, the top of the spring 111 is fixedly connected to a water collecting box 112, a drain port 113 is opened through the top of the water collecting box 112, the filter 3 is placed in the water collecting box 112, and a cleaning plate 115 is connected to the water collecting box 112 via a moving component 114. When impurities accumulate on the filter 3 and rainwater cannot be filtered normally, more and more rainwater will accumulate in the water collecting box 112, causing the overall weight of the water collecting box 112 to become heavier, thereby causing the water collecting box 112 to drop as a whole and compress the spring 111, and then the length of the rope 1143 between the support shaft 21 and the connecting rod 1145 gradually becomes shorter, then the force conditions at both ends of the rope 1143 break the balance, and the spring 2 1141 in the stretched state will gradually restore its original length, thereby driving the cleaning plate 115 to move on the filter 3. When the cleaning plate 115 moves, it will clean the impurities on the filter 3, so that rainwater can pass through the filter 3 normally. As the rainwater decreases, the overall weight of the water collecting box 112 will become smaller, so that the spring 111 recovers and drives the water collecting box 112 to rise, and the length of the rope 1143 between the support shaft 21 and the connecting rod 1145 becomes longer, so that the rope 1143 pulls the cleaning plate 115 on one side, thereby driving the cleaning plate 115 to recover.

[0045] The moving component 114 includes a spring 2 1141 and a guide wheel 3 1142 fixedly connected in the water collecting box 112, and a rope 1143 and a guide wheel 4 1144 fixedly connected to the cleaning plate 115. The spring 2 1141 is fixedly connected to the cleaning plate 115, and the spring 2 1141 is in a stretched state. The rope 1143 passes through the collecting box 2. The rope 1143 is sequentially wound around the guide wheel 4 1144, the guide wheel 3 1142, the guide wheel 2 23 and the guide wheel 1 22. One end of the rope 1143 is fixedly connected to a connecting rod 1145, and the connecting rod 1145 is fixedly connected to the drain outlet 113.

[0046] Embodiment 3

[0047] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-Figure 8 shown.

[0048] By co-arranging the collection box 2 and the filter 3, the possibility of clogging of the device during use can be reduced. The collection box 2 can collect rainwater and block larger debris at the same time. The filter 3 can filter smaller debris in the rainwater. When too much debris accumulates, the filter 3 can be conveniently taken out, cleaned or replaced, so that the device can continue to collect rainwater, increasing the practicality of the device.

[0049] The working principle of the present invention is as follows: first, rainwater enters through the protective cover 10 of the collection box 2, and blocks larger impurities in the rainwater, and then is filtered through the filter screen 3 to remove fine impurities. Secondly, the filtered rainwater flows into the reservoir 1 through the water inlet pipe 8 for storage. When the water level in the reservoir 1 is too high, the excess rainwater is discharged through the overflow pipe 7. When the stored rainwater needs to be used, the water pump 18 is started, and the rainwater flows into the nozzle 5 through the guide pipe 4, the elbow 14, the universal pipe 15 and the pressure pipe 19. The nozzle 5 pressurizes the rainwater and sprays it into fine water droplets to cover the road or green belt. When impurities accumulate on the filter 3 and rainwater cannot be filtered normally, more and more rainwater will accumulate in the water collecting box 112, causing the overall weight of the water collecting box 112 to become heavier, thereby causing the water collecting box 112 to drop as a whole and compress the spring 111, and then the length of the rope 1143 between the support shaft 21 and the connecting rod 1145 gradually becomes shorter, then the force conditions at both ends of the rope 1143 break the balance, and the spring 2 1141 in the stretched state will gradually restore its original length, thereby driving the cleaning plate 115 to move on the filter 3. When the cleaning plate 115 moves, it will clean the impurities on the filter 3, so that rainwater can pass through the filter 3 normally. As the rainwater decreases, the overall weight of the water collecting box 112 will become smaller, so that the spring 111 recovers and drives the water collecting box 112 to rise, and the length of the rope 1143 between the support shaft 21 and the connecting rod 1145 becomes longer, so that the rope 1143 pulls the cleaning plate 115 on one side, thereby driving the cleaning plate 115 to recover. When a large amount of impurities are accumulated on the filter screen 3 and it is impossible to clean it by the cleaning mechanism 11 , the filter screen 3 can be taken out for cleaning or replacement.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
