Description

Technical Field

[0001] The utility model belongs to the technical field of rainwater collection, and in particular relates to a rainwater collection device for sponge cities. Background Art

[0002] A sponge city is a city that, like a sponge, has good "elasticity" in adapting to environmental changes and responding to natural disasters. It can "release" stored water and utilize it when needed. Under the premise of ensuring urban drainage and flood prevention safety, sponge cities maximize the accumulation, infiltration and purification of rainwater in urban areas, promote the reuse of rainwater resources and protect the ecological environment. Therefore, rainwater collection devices are used to collect rainwater. The use of existing rainwater collection devices has at least the following disadvantages: 1. When in use, the existing rainwater collection devices have poor filtering effect on rainwater, resulting in a large amount of impurities in the collected rainwater, which reduces the quality of the collected rainwater and also reduces the utilization value of the collected rainwater; 2. When collecting rainwater, existing rainwater collection devices use filters to filter rainwater, but the filters will become clogged with impurities after long-term use, affecting the filter efficiency of the filters and reducing their practicality; 3. Impurities such as mud and sand are suspended in the rainwater, pass through the filters and enter the storage tank. After sedimentation, they accumulate at the bottom of the storage tank and are difficult to discharge, affecting the water quality and gradually reducing the storage volume of the storage tank.

[0003] To this end, a rainwater collection device for sponge city is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 3 As shown, this embodiment provides a rainwater collection device for a sponge city, comprising:

[0027] A storage box 1 is provided with a silt outlet 2 at the bottom thereof, and the bottom surface of the storage box 1 is funnel-shaped and inclined toward the silt outlet 2; a silt outlet pipe 3 is fixedly connected to the silt outlet 2, and a valve 4 is provided in the silt outlet pipe 3; a water outlet pipe 6 is fixedly connected to the side of the storage box 1;

[0028] Filter mechanism, the top end of the filter mechanism is connected to the water inlet pipe 5, and the bottom end is connected to one side of the top surface of the storage box 1;

[0029] The cleaning mechanism has a fixed end fixed to the top of the storage box 1 away from the filter mechanism, and a movable end of the cleaning mechanism is movably connected to the filter mechanism. The side of the filter mechanism away from the cleaning mechanism is connected to the collection box 7.

[0030] The water inlet pipe 5 is connected to the roof drainage pipe. The rainwater from the roof is drained into the water inlet pipe 5, and then enters the filter mechanism through the water inlet pipe 5 for filtration to filter out impurities in the rainwater, and then enters the storage box 1. The silt in the rainwater settles in the storage box 1. Due to the special inclined shape of the bottom of the storage box 1, silt, sand and gravel flow toward the silt outlet 2. When the amount of silt at the bottom is large, the valve 4 can be opened to discharge the silt from the silt outlet pipe 3 to avoid excessive silt in the storage box 1 affecting the storage volume; the impurities in the filter mechanism can be removed by the cleaning mechanism to avoid excessive clogging by accumulated impurities affecting the filtration efficiency.

[0031] According to a further optimized solution, the filtering mechanism includes a filter box 8 , in which a plurality of filter screens 9 are fixedly connected. The top of the filter box 8 is connected to the water outlet pipe 6 , and the bottom is connected to the storage box 1 .

[0032] The filtering mechanism filters impurities in the rainwater through a number of filter screens 9;

[0033] Furthermore, multiple layers of filter screens 9 may be provided in the filter box 8, and the mesh openings of the filter screens 9 decrease from top to bottom, thereby achieving multi-stage filtration.

[0034] To further optimize the solution, the cleaning mechanism includes a telescopic rod 10, the fixed end of the telescopic rod 10 is fixedly connected to the storage box 1, the movable end of the telescopic rod 10 is fixedly connected to an outer plate 11, and the end of the outer plate 11 close to the filter box 8 is fixedly connected to a number of connecting rods 12, and the several connecting rods 12 pass through the inner wall of the filter box 8 and are fixedly connected to a number of push plates 13. An impurity outlet 14 is provided at the end of the filter box 8 away from the cleaning mechanism, and the filter box 8 is connected to the collection box 7 through the impurity outlet 14. A sealing plate 15 is buckled on the impurity outlet 14, and a number of connecting rods 12 pass through the push plate 13 and the inner cavity of the filter box 8 and are fixedly connected to the sealing plate 15.

[0035] The cleaning mechanism is extended and retracted by the telescopic rod 10, thereby pushing the push plate 13 to move horizontally above the filter screen 9, pushing the impurities on the filter screen 9 into the collection box 7 on one side of the filter box 8, and the sealing plate 15 moves with the movement of the push plate 13. Under normal conditions, the sealing plate 15 is in contact with the outer wall of the filter box 8 to ensure that the filter box 8 is sealed. When the telescopic rod 10 drives the push plate 13 to move along the filter screen 9, the sealing plate 15 is separated from the outer wall of the filter box 8, providing a path for impurities to pass through, so that the impurities fall into the collection box 7 through the impurity outlet 14.

[0036] The telescopic rod 10 may be a hydraulic telescopic rod 10 or an electric telescopic rod 10 .

[0037] According to a further optimized solution, a brush 16 is fixed to the bottom of the push plate 13 , and the brush 16 abuts against the filter screen 9 .

[0038] The brush 16 is convenient for cleaning the filter screen 9 .

[0039] To further optimize the solution, a debris discharge door 17 is provided at the bottom of the collection box 7 .

[0040] The impurities in the collecting box 7 are discharged through the impurity discharge door 17.

[0041] As a further optimization solution, an overflow pipe 18 is connected to the top of the storage box 1.

[0042] When too much rainwater is collected in the storage box 1, the excess rainwater is discharged through the overflow pipe 18, and the overflow pipe 18 can discharge the rainwater into the municipal drainage pipe.

[0043] According to a further optimized solution, a water pump 19 is fixedly connected to the outlet pipe 6 , and a float 20 is fixedly connected to the outer side of the water inlet end of the outlet pipe 6 .

[0044] The water pump 19 is used to pump out the rainwater stored in the storage box 1 for daily use, and the float 20 can keep the water inlet end of the outlet pipe 6 close to the water surface to avoid pumping out silt.

[0045] To further optimize the solution, a protective cover 21 is provided on the outer cover of the cleaning mechanism.

[0046] The protective cover 21 protects the telescopic rod 10 from being eroded by sunlight and rain, thereby extending its service life.
