Description

Technical Field

[0001] The present invention mainly relates to the field of rainwater treatment equipment, in particular to a fishbone-shaped sponge urban road structure provided with a honeycomb-type water storage and filtering device. Background Art

[0002] With the intensification of water crisis and rain and flood hazards, collecting and utilizing rainwater for comprehensive management of water resources has become an important emerging topic. When encountering heavy rain, rainwater is stored and filtered through the sponge city water storage road structure. However, in the actual rainfall process, under the scouring effect of rainwater, the accumulation of stones, leaves and other deposits on the road surface will hinder the penetration of rainwater. On the one hand, the drainage effect is poor, which is easy to cause floods. On the other hand, it will react with rainwater, turning rainwater into sewage. The quality of the collected rainwater is poor, which increases the cost of subsequent water treatment.

[0003] In the search of related topics, patent CN 105056616A discloses a rainwater filter, which uses a filter mesh and a multi-layer filter medium to perform multiple filtration on rainwater, and cleverly arranges water holes on the central collecting pipe. The total opening area of ​​the water holes on the wall of the central collecting pipe increases or is equal from the lower layer to the upper layer. When the water level outside the filter is low, rainwater enters the central collecting pipe from the lower part of the filter. Since the total area of ​​the water holes in the lower layer of the central collecting pipe is small, the flow rate of rainwater entering the central collecting pipe is limited to a certain extent, causing the external rainwater water level to rise. This not only prolongs the contact time between rainwater and the filter medium at the lower end, but also makes the filter medium at the upper end of the filter fully utilized, thereby greatly improving the utilization rate of the filter medium, prolonging the contact time between rainwater and the filter medium, and making rainwater have sufficient contact with the filter medium, which can effectively remove pollutants such as particulate matter, heavy metals and organic matter in rainwater, and achieve standard discharge or reuse of rainwater.

[0004] Although this filtering method achieves multiple filtration, it still does not solve the problem of poor drainage in rainy weather. Summary of the invention

DETAILED DESCRIPTION

[0017] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the application.

[0018] The standard parts used in this application can all be purchased from the market, and special-shaped parts can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, and bonding in the existing technology, and the components used for circuit connection are all conventional models in the existing technology.

[0019] At the same time, in order to clearly express the connection relationship and working principle between the components and highlight the key points, the drawings in the specification are organized and drawn in the form of simple diagrams. One simple diagram can correspond to a variety of materials and actual external structural shapes.

[0020] The fishbone-shaped sponge urban road structure provided with a honeycomb-type water storage and filtration device comprises a shell 1, and a plurality of connecting pipes 2 are provided on the top of the shell 1. Figure 1 As shown, the position corresponding to the shell 1 is the main road, and the position of the connecting pipe 2 corresponds to the auxiliary road. The setting of parameters such as length, spacing, number, volume, etc. can be based on the actual road conditions and can be set using the existing sewer structure, so that the connection structure of the connecting pipe 2 and the shell 1 is in the shape of a fishbone. It should be noted that all the connecting pipes 2 connected to the shell 1 are located at the top of the shell 1, so as to ensure that rainwater can flow into the shell 1.

[0021] The connecting pipe 2 is in communication with the housing 1. A first filter screen 3 and a second filter screen 4 are arranged in the connecting pipe 2. The aperture of the first filter screen 3 is larger than that of the second filter screen 4. The second filter screen 4 is located between the first filter screen 3 and the housing 1. Figure 2As shown, the first filter 3 is used to filter and block garbage, leaves and other items on the ground, and the second filter 4 is used to filter and block stones, gravel and other items, reducing the obstruction of drainage caused by the accumulation of objects on the ground during rainfall. When there are too many leaves, garbage, etc. accumulated on the first filter 3 and continue to hinder the flow of rainwater, they can also be cleaned in time.

[0022] As attached Figure 2 As shown, a water pipe 5 is provided on the side of the shell 1, and a baffle 6 is provided below the water pipe 5. The baffle 6 is slidably connected to the inner wall of the shell 1, and an elastic buffer 7 is provided at the bottom of the baffle 6. A filter tube 8 is provided on one side of the shell 1, and the filter tube 8 is located below the baffle 6. When the baffle 6 slides downward, it can slide below the filter tube 8; when the rainfall is less, rainwater flows out directly through the water pipe 5, which neither affects the timely discharge of rainwater nor occupies the filter layer, thereby reducing the later maintenance cost and improving the utilization rate of the sponge city road structure.

[0023] A water storage tank 9 is provided at one end of the filter tube 8, and a filter medium 10 and a liquid level sensor 11 are provided in the water storage tank 9. The filter medium 10 is a honeycomb type; the honeycomb type filter medium 10 is an existing filter medium 10, and the honeycomb structure is stable and firmly fixed, and is suitable for being arranged in the water storage tank 9. It can be composed of one or more of compost, vermiculite, perlite, sand, zeolite, peat, etc., and can also be composed of artificial multi-porous materials such as activated carbon and ion exchangers, and is used to filter rainwater and use it as reclaimed water.

[0024] A water pump 12 and a control cabinet 13 are provided on one side of the water storage tank 9, and the water pump 12 and the liquid level sensor 11 are both connected to the control cabinet 13. The water pump 12 is used to extract water from the water storage pipe, and the other end is connected to the water pipe. The control cabinet 13 can control the water pump 12 to directly pump water. When the liquid level sensor 11 detects that the rainwater in the water storage tank 9 is full, it sends a signal to the control cabinet 13, and the control cabinet 13 controls the water pump 12 to rotate and discharge the water in the water storage tank 9 according to the set discharge volume. Preferably, the control cabinet 13 can adopt a PLC control system, which has mature technology and stable control.

[0025] Furthermore, a wheel disc 14 is provided at the bottom of the housing 1 of the baffle 6, a traction rope 15 is provided on the wheel disc 14, one end of the traction rope 15 passes through the bottom of the housing 1 and is connected to the baffle 6, a motor 16 is provided on the wheel disc 14, and the motor 16 is connected to the control cabinet 13. Figure 1 As shown, the purpose of setting the wheel 14 is to provide an auxiliary function. When the amount of rain is not large and the rainwater needs to be filtered and retained in the water storage tank 9, the control cabinet 13 controls the motor 16 to rotate, and the baffle 6 is pulled down through the wheel 14 and the traction rope 15 to expose the filter tube 8, so that the rainwater enters the water storage tank 9 through the filter tube 8.

[0026] As an optimization, the filter tube 8 is connected to the bottom of the water storage tank 9, and the filter medium 10 is vertically set up in the water storage tank 9. Not only can the vertical space occupied by the water storage tank 9 be reduced, but also the contact time between the filter medium 10 and rainwater is prolonged, thereby improving the filtering efficiency.

[0027] Furthermore, a first one-way valve 17 is provided on the filter tube 8 to prevent the filtered rainwater from re-entering the housing 1 .

[0028] As an optimization, the first filter screen 3 and the second filter screen 4 are both slidably connected to the connecting pipe 2, so that the first filter screen 3 and the second filter screen 4 can be taken out and cleaned conveniently and quickly.

[0029] As an optimization, the elastic buffer 7 is a spring. Since the housing 1 is connected to the filter tube 8, the elastic buffer 7 cannot adopt a fluid buffer or an air compression buffer, but can only adopt a solid part, and adopts a spring, which is firmly fixed and will not interfere with the cooperation between the baffle 6 and the filter tube 8. As an optimization, the liquid level sensor 11 is a immersion type liquid level sensor 11, which has accurate measurement, high precision and fast response speed. Considering that the water storage tank 9 is basically set at the bottom of the road, it is more appropriate to use the immersion type liquid level sensor 11 to calculate the water volume in the closed tank.

[0030] Furthermore, a sealing plate 18 is fixedly connected to one side of the filter medium 10, and the sealing plate 18 is located on the side of the filter medium 10 away from the filter tube 8. A second one-way valve 19 is provided on the sealing plate 18. The sealing plate 18 divides the filter tank into two cavities. Combined with the setting of the second one-way valve 19, the filtered rainwater is isolated from the filter medium 10, thereby further ensuring the quality of the filtered rainwater.

[0031] Directions: In rainy weather, when rainwater flows through the connecting pipe, it passes through the first filter screen and the second filter screen and enters the housing. When the amount of rainwater is small, it is discharged through the water pipe. When the amount of rainwater is large, the baffle is pressed down to a certain extent, and the filter tube is exposed. The rainwater enters the filter tube and flows into the water storage tank to react with the filter medium and is stored. When it needs to be discharged, it is discharged by the water pump.
