Description

Technical Field

[0001] This invention belongs to the field of road drainage, specifically a filtration device for road drainage pipe networks based on engineering design. Background Technology

[0002] Filtration devices for road drainage networks, based on engineering design, are generally integrated filtration, storage, and water recycling systems located at sewer inlets. When rainwater is present on the road, it flows into the sewer and is filtered through the filter elements at the top of the integrated filtration, storage, and water recycling system. The filtered water is then stored inside the system and connected to a water treatment plant, allowing the water to be discharged there for further treatment and reuse, thus completing water recycling. However, the following drawbacks still exist: When the filter at the top of the equipment filters out too much impurities and debris, these impurities and debris can easily cause blockages, preventing the water on the road from draining quickly. When emergency treatment is needed and the filter is removed for cleaning and replacement, the water is directly discharged into the equipment without being filtered again, which reduces the efficiency of water recycling. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention has four filter chambers on a rotating cylinder, one of which is located below the normal drainage position. When the filter chamber is clogged due to excessive filtration of impurities and garbage, the rotation of the rotating cylinder can transfer the filter chambers in other positions to the normal drainage position, which facilitates continuous drainage filtration, ensures drainage efficiency, and can clean impurities and garbage without stopping drainage. 2. In this invention, when the filter chamber below a normal drainage station is blocked or there is waterlogging on the road, the accumulated water acts on the top of the baffle to push it to rotate downwards, so that the accumulated water can be discharged from the square groove into the collection box, which facilitates auxiliary drainage, improves the drainage effect of water accumulation on the road, and facilitates continuous drainage work when the filter chamber position is changed. 3. In this invention, when the amount of water on the road is not large and the ordinary drainage station is blocked, the baffle rotates downward at a small angle, which is suitable for ordinary drainage. However, when there is flooding on the road, the baffle is subjected to greater pressure, causing it to rotate at a larger angle. After rotating at a large angle, the electromagnet is energized to drive the locking rod to move and lock the cover in place, preventing the cover from being opened by impact and affecting pedestrians or vehicles to wade through the water. At the same time, it prevents the stored garbage from being washed out of the ground. 4. In this invention, a limiting groove is opened in the baffle, and the support rod is set in the limiting groove and is longitudinally limited, so that under the elastic force of the first spring, the baffle can keep horizontal and block the square groove. After the baffle rotates, the first spring is compressed, and the pressure on the first pressure sensor changes, which makes it easier for the control system to understand the road conditions. 5. In this invention, the pressure changes of both the second and first pressure sensors are transmitted to the control system for data analysis. When the pressure value of the second pressure sensor increases while the pressure value of the first pressure sensor remains unchanged, normal drainage is performed. When the pressure value of the second pressure sensor remains unchanged while the pressure value of the first pressure sensor increases, it indicates that there is a blockage. When the pressure values ​​of both the second and first pressure sensors increase, it indicates that there is waterlogging, which facilitates the monitoring of road conditions.

The bottom filter element 202 includes a rotating cylinder 2021 with a central groove 2022 in its center. Four filter chambers 2023 are equally spaced on the rotating cylinder 2021, positioned at equal angles outside the central groove 2022.

The general drainage station and the impurity treatment station are located above two centrally symmetrical filter chambers 2023. The two auxiliary drainage stations are located above the other two filter chambers 2023. The rotating cylinder 2021 is equipped with four filter chambers 2023. One of the filter chambers 2023 is located below the general drainage station. When it becomes clogged due to excessive impurities and debris filtered out, the rotation of the rotating cylinder 2021 can move the filter chambers 2023 in other positions to below the general drainage station, facilitating continuous drainage and filtration, ensuring drainage efficiency, and cleaning impurities and debris without stopping drainage.

The two ends of the cover 2042 are symmetrically provided with slots 2043.

[0022] The auxiliary drainage component 205 includes two square grooves 2051 symmetrically opened on the top cover 201. A baffle 2052 is installed inside each square groove 2051. When the filter chamber 2023 below the ordinary drainage station is blocked or the road is flooded, the accumulated water acts on the top of the baffle 2052, pushing it downwards and allowing the accumulated water to drain from the square grooves 2051 into the collection box 101. This facilitates auxiliary drainage, improves the drainage effect of accumulated water on the road, and allows for continuous drainage when the filter chamber 2023 is repositioned. The baffle 2052 seals the square grooves 2051. A rotating shaft 2053 is installed at the far end of each of the two square grooves 2051. The rotating shaft 2053 is rotatably connected to the top cover 201. A limiting groove 2054 is opened on the rotating shaft 2053. A fixing anti-impact component 211 is provided on the baffle 2052. A support rod 2056 is provided inside the limiting groove 2054. A sliding plate 2057 is symmetrically installed at both ends of the 2056. The sliding plate 2057 is movably installed inside the slide groove 2055, which is symmetrically opened on both sides of the square groove 2051. A first spring 2058 is installed at the bottom of the sliding plate 2057. A first pressure sensor 2059 is installed at the bottom of one of the first springs 2058. The bottoms of the first pressure sensor 2059 and the other first springs 2058 are installed on the inner bottom wall of the slide groove 2055. A limiting groove 2054 is opened in the baffle 2052. The support rod 2056 is set in the limiting groove 2054 and is longitudinally limited, so that under the elastic force of the first spring 2058, the baffle 2052 can keep horizontal and block the square groove 2051. After the baffle 2052 rotates, the first spring 2058 is compressed, and the pressure on the first pressure sensor 2059 changes, which facilitates the control system to understand the road conditions.

[0023] The fixed anti-impact component 211 includes a pressure plate 2112 movably disposed inside the limiting groove 2054. The pressure plate 2112 is located on the side of the support rod 2056 away from the rotating shaft 2053.

A movable plate 2114 is movably installed inside the movable groove 2113. Connecting rods 2115 are symmetrically installed between the movable plate 2114 and the pressure plate 2112. The movable plate 2114 is located away from the pressure plate 2112. A support spring 2116 is symmetrically installed on one side of the movable plate 2114. One end of the support spring 2116 is fixedly connected to the inner wall of the movable groove 2113. A conductive rod 2117 is installed on the movable plate 2114. Contacts 2118 are symmetrically installed on the inner walls of both ends of the movable groove 2113. The contacts 2118 are located on the side of the conductive rod 2117 away from the pressure plate 2112. A battery power transmission device is provided on the baffle 2052. An electromagnet 2111 is installed on the side of the baffle 2052 away from the rotating shaft 2053 and close to the processing groove 2041. Two contacts 2118 are connected to the movable plate 2114. 118. The battery power transmission equipment and electromagnet 2111 are connected in series. Rod slots 2119 are provided on the inner walls of the two sides of the processing tank 2041, near the two square slots 2051. A locking rod 21110 is movably installed inside the rod slot 21119. A return spring 21112 is installed at the end of the locking rod 21110 away from the processing tank 2041. One end of the return spring 21112 is fixedly connected to the inner wall of the end of the rod slot 2119. A magnetic block 21111 is installed at the end of the locking rod 21110 away from the processing tank 2041. The positions of the lever 21110 and the slot 2043 correspond. When the amount of water on the road is not large and the ordinary drainage station is blocked, the baffle 2052 rotates downward at a small angle, which is suitable for ordinary drainage. However, when there is waterlogging on the road, the baffle 2052 is subjected to greater pressure, causing it to rotate at a larger angle. After rotating at a large angle, the electromagnet 2111 is energized to drive the lever 21110 to move and lock the cover 2042 in place, preventing the cover 2042 from being opened by impact and affecting pedestrians or vehicles to wade through the water. At the same time, it prevents the stored garbage from being washed out of the ground.

[0024] The top of the collection box 101 is provided with a positioning groove 106 at equal angles, and the bottom of the top cover 201 is provided with a positioning block 208 at equal angles. The positioning block 208 is inserted into the positioning groove 106. The top of the rotating cylinder 2021 is provided with a limiting ring 206, and the top cover 201 is provided with a limiting ring groove 207. The limiting ring 206 is rotatably installed inside the limiting ring groove 207. The cross-section of the limiting ring 206 and the cross-section of the limiting ring groove 207 are both T-shaped.

[0025] The drainage component includes a recovery pipe 102 installed at the bottom of one side of the collection box 101, a first solenoid valve 104 installed on the recovery pipe 102, a drain pipe 103 installed on the recovery pipe 102, the drain pipe 103 being located on the side of the first solenoid valve 104 near the collection box 101, and a second solenoid valve 105 installed on the drain pipe 103.

[0026] The drainage status monitoring component 3 includes a sliding frame 301 fixedly installed on the side wall of the collection box 101. A sliding block 302 is slidably installed inside the sliding frame 301. An impact plate 303 is installed on the sliding block 302. The top of the impact plate 303 is provided with an inclined surface. The impact plate 303 is located below the drainage channel 203. A second spring 304 is installed at the bottom end of the sliding block 302. A second pressure sensor 305 is installed at the bottom end of the second spring 304. The second pressure sensor 305 is fixedly installed on the inner bottom wall of the sliding frame 301. The pressure value changes of the second pressure sensor 305 and the first pressure sensor 2059 are transmitted to the control system for data analysis. When the pressure value of the second pressure sensor 305 increases while the pressure value of the first pressure sensor 2059 remains unchanged, normal drainage is performed. When the pressure value of the second pressure sensor 305 remains unchanged while the pressure value of the first pressure sensor 2059 increases, it indicates that there is a blockage. When the pressure values ​​of both the second pressure sensor 305 and the first pressure sensor 2059 increase, it indicates that there is waterlogging. This facilitates the monitoring of road conditions.

[0027] Working principle: During the road construction phase, the collection box 101 is pre-buried underground. One end of the recycling pipe 102 is connected to the water recycling and treatment plant through an underground pipeline. One end of the second solenoid valve 105 is connected to the urban water body, such as rivers or groundwater. Then, a top cover 201 is placed on the top of the collection box 101, so that the positioning block 208 is correspondingly inserted into the positioning groove 106, and the impact plate 303 is located below the drainage groove 203. The installation is completed, and the top wall of the top cover 201 is flush with the road surface, which facilitates the passage of pedestrians or vehicles. During normal drainage, water on the ground enters the filter chamber 2023 located below the ordinary drainage station from the drainage trough 203. After being filtered by the filter plate 2025 at the bottom of the filter chamber 2023, impurities and garbage in the water are filtered and left on the filter plate 2025. The filtered water enters the collection tank 101 for storage. After the first solenoid valve 104 is opened, the water pump installed on the pipeline can pump the water stored in the collection tank 101 into the water treatment plant for treatment and reuse. During normal drainage, the filtered water flows downwards and impacts the top surface of the impact plate 303, pushing the impact plate 303 downwards and compressing the second spring 304. This causes the second pressure sensor 305 to experience increased pressure, generating an increased electrical signal, which is then transmitted to the control system. When the pressure on the second pressure sensor 305 returns to its original value, it indicates that there is not much water accumulation on the road, or that the filter plate 2025 in the filter chamber 2023 located below the normal drainage station may be clogged with impurities and debris, requiring manual handling. At this point, the above two situations are judged: When there is water accumulation on the road and drainage is required, the water enters the lower filter chamber 2023 from the drainage channel 203, but cannot continue to drain downwards. When the water accumulation inside the filter chamber 2023 is severe and water cannot continue to enter, as the amount of water increases, the water overcomes the elastic force of the first spring 2058 and pushes the baffle 2052 to rotate downwards around the rotating shaft 2053 as the rotation center, so that the water can enter the filter chamber 2023 below the square channel 2051, and then enter the collection box 101 after filtration. When the filter chamber 2023 located below the ordinary drainage station is blocked, auxiliary drainage is performed. At this time, due to the increase in the elastic force of the first spring 2058, the pressure on the first pressure sensor 2059 increases, and the electrical signal is transmitted to the control system. When both the second pressure sensor 305 and the first pressure sensor 2059 experience their original pressure, it indicates that the water on the road has been largely drained. When both the second pressure sensor 305 and the first pressure sensor 2059 experience their original pressure, it indicates that the filter chamber 2023 located below the ordinary drainage station is blocked. When the control system receives the second signal state, it controls the drive motor 210 to be energized once. An electromagnetic relay is installed on the external circuit of the drive motor 210. By controlling the energizing time of the drive motor 210, the output shaft of the drive motor 210 rotates only 90 degrees at a time, thereby driving the rotating cylinder 2021 to rotate 90 degrees. This causes the other filter chamber 2023 to move below the normal drainage station. After the clogged filter chamber 2023 moves below the impurity treatment station, the staff removes the cover 2042 to open the treatment tank 2041. The impurities and garbage inside the filter chamber 2023 are then cleaned and treated from the treatment tank 2041. During the cleaning process, normal water drainage is not affected. When the pressure on the second pressure sensor 305 increases and the pressure on the first pressure sensor 2059 increases, it indicates that the road is flooded and the drainage volume is too large. At this time, some water is discharged from the drainage channel 203 into the collection box 101, and the other part of the water is discharged from the square channel 2051 into the collection box 101 after the baffle 2052 rotates downward. When the road is flooded, the water pressure is too high, causing the baffle 2052 to rotate downwards at a large angle. During this downward rotation, the support rod 2056 moves towards and contacts the pressure plate 2112, pushing it to continue moving. At its extreme position, the terminals at both ends of the conductive rod 2117 contact the two contacts 2118, energizing the electromagnet 2111. At this point, the baffle 2052 rotates to the position corresponding to the electromagnet 2111 and the rod groove 2119. Waterproof sealing rings are installed in the grooves of the connecting wires of the contacts 2118 and the electromagnet 2111. When the electromagnet 2111 is energized, it generates a repulsive force on the magnetic block 21111 on the lever 21110, pushing... The movable lever 21110 moves toward the treatment tank 2041 and engages with the slot 2043, locking the cover 2042 to prevent a large amount of water from entering the filter chamber 2023 from the treatment tank 2041 and the cover 2042. This creates a strong "supporting force" under the cover 2042. If the supporting force exceeds the weight of the cover 2042, it will push the cover 2042 open. This could affect road traffic and wash stored garbage and impurities onto the ground, causing pollution. At the same time, the control system automatically controls the second solenoid valve 105 to open and the first solenoid valve 104 to close, allowing the water in the collection box 101 to be directly discharged into rivers or groundwater, thereby mitigating road flooding.
