Description

Technical Field

[0001] This utility model relates to the field of bridge deck rainwater collection and treatment technology, specifically a bridge deck runoff rainwater collection and diversion treatment system. Background Technology

[0002] Bridge deck rainwater harvesting and treatment refers to a system that uses bridge deck drainage facilities to collect, store, and utilize rainwater. The collected rainwater is used to irrigate the green belts under the bridge, which saves water for greening, as well as manpower and material resources.

[0003] A search revealed that the announcement number is CN215052067U, and the name is "A Bridge Deck Rainwater Collection Device," which includes: a water storage tank, a diversion pipe, a downpipe, a drainage pump, and a drainage pipe. Research and analysis revealed that although it can filter and store the collected water, and ultimately reuse the stored rainwater, greatly improving resource reuse and avoiding resource waste, it still has the following shortcomings to some extent.

[0004] For example, the aforementioned bridge runoff rainwater collection and treatment system is mainly designed for conventional rainwater and road cleaning water. It cannot separately treat liquids leaked in hazardous chemical transportation accidents or fire-fighting water drainage. Due to the complexity and toxicity of the pollutants, the treatment is difficult and exceeds the system's capacity. The existing system's mode switching mechanism after an emergency is unclear, relying on manual switching and diversion, which can easily delay the collection of toxic and harmful liquids. It lacks an automated system mode switching design, making it difficult to respond to accidents quickly and effectively. At the same time, it cannot clean the filtered leaves and other impurities, which can easily cause filter screen clogging and affect filtration efficiency. In order to solve the above technical problems, we have designed a bridge runoff rainwater collection and diversion treatment system. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge deck runoff rainwater collection and diversion treatment system, which has the advantages of being able to detect and treat the collected water in real time, preventing toxic and harmful substances from entering the rainwater treatment system, and cleaning the filtered impurities to avoid clogging the mesh. It solves the problems of not being able to monitor the water in real time, which can easily lead to toxic and harmful substances polluting the rainwater treatment system, and the inability to clean the filtered impurities, which can cause the mesh to become clogged and affect the filtration efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge deck runoff rainwater collection and diversion treatment system, comprising a rainwater collection tank, a filter tank fixedly connected to the top of the rainwater collection tank, a filter screen plate fixedly installed in the inner cavity of the filter tank, a fixed shell fixedly connected to the rear side of the filter tank, a drive motor connected to the right side of the fixed shell by bolts, a reciprocating screw riveted to the output end of the drive motor, an installation cross plate movably sleeved on the surface of the reciprocating screw, a support mechanism fixedly connected to the bottom of the installation cross plate, a brush connected to the bottom of the support mechanism by bolts, a diversion pipe connected to the bottom of the right side of the rainwater collection tank, a first solenoid valve, a second solenoid valve and a third solenoid valve respectively installed and connected to the surface of the diversion pipe, a sewage treatment tank and a rainwater treatment tank respectively connected to the front and rear sides of the bottom of the diversion pipe, and a water quality sensor module fixedly connected through the bottom of the left side of the inner cavity of the rainwater collection tank.

[0007] Preferably, the support mechanism includes a support housing, a support spring is installed at the top of the inner cavity of the support housing, a support slide rod is fixedly connected to the bottom of the support spring, and the bottom of the support slide rod passes through the support housing and is fixedly connected to the brush.

[0008] Preferably, a drain pipe is fixedly connected to the top of the filter box, and a bridge body is connected to the top of the drain pipe. Drain holes are provided on both the front and rear sides of the top of the bridge body.

[0009] Preferably, a through opening is provided on the rear side of the inner cavity of the filter box, and a guide slide rod is fixedly connected to the inner cavity of the through opening. Water supply pipes are fixedly connected to the bottom right side of both the sewage treatment box and the rainwater treatment box.

[0010] Preferably, slag discharge openings are provided on both the left and right sides of the inner cavity of the filter box, and the surface of the reciprocating screw is movably connected to the fixed shell through bearings.

[0011] Preferably, a slag discharge shell is fixedly connected to both the left and right sides of the filter box, a slag collection box is placed at the bottom of the inner cavity of the slag discharge shell, and a cover plate is installed on the outer side of the slag discharge shell by a hinge.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The water quality sensor module monitors the water body. When no pollutants are detected in the water, it opens the first and third solenoid valves to guide the water into the rainwater treatment tank for ecological purification before discharge. When the water quality sensor module detects pollutants in the water, it controls the third solenoid valve to close and opens the first and second solenoid valves to guide the polluted water into the sewage treatment tank for centralized treatment. This allows for real-time monitoring of the collected water and prevents toxic and harmful substances from entering the rainwater treatment system and causing large-scale water pollution.

[0014] The drive motor rotates the reciprocating screw, causing the brush at the bottom of the mounting plate to move left and right on the surface of the filter screen. This sweeps the filtered debris to both sides of the filter box, preventing debris from accumulating on the top of the filter screen and clogging the mesh, thus ensuring filtration efficiency.

A support mechanism 18 is fixedly connected to the bottom of the mounting plate 19. The bottom of the support mechanism 18 is bolted to... A brush 21 is connected to the bottom right side of the rainwater collection tank 1, and a diversion pipe 10 is connected to it. The surface of the diversion pipe 10 is respectively connected to a first solenoid valve 7, a second solenoid valve 8 and a third solenoid valve 9. The front and rear sides of the bottom of the diversion pipe 10 are respectively connected to a sewage treatment tank 13 and a rainwater treatment tank 11. A water quality sensor module 14 is fixedly connected through the bottom left side of the inner cavity of the rainwater collection tank 1. The water quality sensor module 14 is assembled from various sensors, such as: pH sensor, dissolved oxygen sensor, oxidation-reduction potential sensor and ammonia nitrogen sensor, etc.

[0022] Please see Figure 4 The support mechanism 18 includes a support housing 25. A support spring 26 is installed at the top of the inner cavity of the support housing 25. By setting the support spring 26, the elastic potential energy can be released to push the brush 21 into close contact with the filter screen 22, so that the debris is cleaned more thoroughly. A support slide rod 24 is fixedly connected to the bottom of the support spring 26. The bottom of the support slide rod 24 passes through the support housing 25 and is fixedly connected to the brush 21.

[0023] Please see Figure 1 The top of the filter box 2 is fixedly connected to a drain pipe 3, and the top of the drain pipe 3 is connected to a bridge body 4. Drain holes 5 are provided on both the front and rear sides of the top of the bridge body 4. By setting the drain holes 5, the water on the bridge body 4 can flow into the drain pipe 3.

[0024] Please see Figure 3 The filter box 2 has a through opening 20 on the rear side of its inner cavity. The front side of the mounting plate 19 passes through the through opening 20 and is slidably connected to the guide slide rod 17. This can guide and limit the mounting plate 19, making its movement more stable. The guide slide rod 17 is fixedly connected to the inner cavity of the through opening 20. The bottom right side of the sewage treatment box 13 and the rainwater treatment box 11 are both fixedly connected to the water supply pipe 12. By setting the water supply pipe 12, the treated water can be discharged.

[0025] Please see Figure 5 The filter box 2 has slag discharge openings 29 on both the left and right sides of the inner cavity. By setting the slag discharge openings 29, the debris swept from both sides can enter the slag discharge shell 15. The surface of the reciprocating screw 28 is connected to the fixed shell 27 by bearings.

[0026] Please see Figure 2 and Figure 3 The filter box 2 is fixedly connected to the left and right sides with a slag discharge shell 15.

A cover plate 16 is installed on the outside of the slag discharge shell 15 by a hinge.

[0027] In use, the water quality sensor module 14 is connected to an external automated detection system. Water on the bridge body 4 flows into the filter box 2 through the drain pipe 3. The filter screen 22 filters out impurities in the water. The filtered water then enters the rainwater collection box 1 for collection. The water quality sensor module 14 monitors the water in the rainwater collection box 1. Under normal rainfall conditions, when the rainwater collection box 1 is full, the water quality sensor module 14 monitors the water and transmits the monitoring information to the automated detection system to confirm the water quality. When no pollutants are detected in the water, the first solenoid valve 7 and the third solenoid valve 9 are opened to guide the water into the rainwater treatment box 11 for ecological purification treatment before discharge. When harmful substances such as oil and chemicals are present on the bridge surface... When a leak occurs, the liquid flows into the rainwater collection tank 1. The water quality sensor module 14 detects the presence of pollutants in the water. At this time, it controls the third solenoid valve 9 to close and the first solenoid valve 7 and the second solenoid valve 8 to guide the polluted water into the sewage treatment tank 13 for centralized treatment. This allows for real-time monitoring of the collected water, preventing toxic and harmful substances from entering the rainwater treatment system and causing large-scale water pollution. The drive motor 6 is connected to the remote control circuit. The drive motor 6 drives the reciprocating screw 28 to rotate, causing the brush 21 at the bottom of the mounting plate 19 to move left and right on the surface of the filter screen 22. This sweeps the filtered debris to both sides of the filter box 2, preventing debris from accumulating on the top of the filter screen 22 and causing mesh blockage, thus ensuring filtration efficiency.

[0028] In summary, this bridge deck runoff rainwater collection and diversion treatment system, through the coordinated use of rainwater collection tank 1, filter tank 2, drive motor 6, first solenoid valve 7, second solenoid valve 8, third solenoid valve 9, diversion pipe 10, rainwater treatment tank 11, sewage treatment tank 13, water quality sensor module 14, brush 21, filter screen 22, and reciprocating screw 28, solves the problems of the inability to monitor water bodies in real time, which easily leads to the pollution of the rainwater treatment system by toxic and harmful substances, and the inability to clean the filtered impurities, resulting in mesh blockage and affecting filtration efficiency.
