The municipal drainage system planning is a component of the municipal master plan. The municipal drainage system is usually composed of drainage pipes and sewage treatment plants. In the case of sewage and rainwater diversion system, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled; rainwater runoff is collected by drainage pipes and discharged into nearby water bodies.

[0003] A Chinese patent with publication number CN210917687U discloses a drainage device for a municipal drainage pipeline, including a municipal road, a green belt is arranged on one side of the municipal road, a drainage channel is arranged on the municipal road, the bottom end of the drainage channel is connected to the sewer, an outer frame is arranged at the opening above the drainage channel, an inner frame is arranged on the inner side of the outer frame, and a filter grid plate is arranged on the inner side of the inner frame.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the filter grid plate filters and discharges the accumulated water, but during heavy rain, the flow of rainwater on the road is large, causing large debris to flow to the filter grid plate, blocking the drainage holes on the filter grid plate, and then causing sewage formed by rainwater mixed with debris to accumulate on the road, causing pollution to the municipal roads. Summary of the invention

[0005] In order to alleviate the problem of pollution to municipal roads, the present application provides a municipal road drainage system.

[0006] The municipal road drainage system provided in this application adopts the following technical solution:

[0007] A municipal road drainage system comprises a municipal road body, wherein a drainage well is provided on the municipal road body, a sliding hole is opened at the bottom of the drainage well, a sliding rod is slidably connected in the sliding hole, one end of the sliding rod is connected to a support rod, one end of the support rod is connected to a support spring, one end of the support spring is arranged at the bottom of the drainage well, the support spring is sleeved outside the sliding rod, one end of the support rod is hinged with a filter plate, the filter plate blocks the wellhead of the drainage well, a placement groove is provided at the opening of the drainage well, the placement groove is connected to the side wall of the drainage well, a first driving member for driving the filter plate to swing is provided in the drainage well, a distance sensor is provided at the bottom of the sliding hole, and the distance sensor is electrically connected to the first driving member through a control system.

[0008] By adopting the above technical solution, when in use, when a large amount of rainwater mixed with debris accumulates on the filter plate, the weight on the filter plate increases, the support spring is compressed, and the support rod moves downward. When the distance sensor measures that the distance from the bottom surface of the sliding rod to the sensing end of the distance sensor reaches a threshold, the distance sensor starts the first driving member through the control system, and the first driving member drives the filter plate to swing, so that the debris above it shakes on the filter plate, reducing the possibility of debris clogging the drainage holes on the filter plate, so that water can be discharged into the drainage well. Therefore, the present application alleviates the problem of sewage formed by rainwater mixed with debris accumulating on the road and polluting municipal roads.

[0009] Optionally, the side wall of the placement groove is provided with a plurality of first holes, and a guide rod is slidably connected in the plurality of first holes, one end of the guide rod is connected to an arc plate, a return spring is provided on the outer sleeve of the guide rod, one end of the return spring is connected to the side wall of the placement groove, and the other end is connected to the arc plate, and the plurality of arc plates together enclose an anti-blocking ring, and the side wall of the filter plate is tightly attached to the inner ring wall of the anti-blocking ring.

[0010] By adopting the above technical solution, during use, when the filter plate swings, the filter plate squeezes the arc plate, the arc plate squeezes the return spring, and the guide rod slides with the first hole, so that the inner ring side wall of the anti-blocking ring always fits the filter plate, reducing the possibility of debris entering the gap between the filter plate and the placement groove and affecting the normal swing of the filter plate.

[0011] Optionally, the first driving member includes a plurality of electromagnets, the plurality of electromagnets are embedded in the placement grooves, the plurality of electromagnets are surrounded by a circular ring, the distance sensor is electrically connected to the plurality of electromagnets through a control system, the bottom of the filter plate is connected to a rotating rod, the filter plate is provided with a lifting hole, one end of the rotating rod is inserted into the lifting hole and slidably cooperates with the lifting hole, the bottom of the rotating rod is connected to a mounting plate, the bottom of the mounting plate is provided with a ball groove, the outer sleeve of the rotating rod is provided with a swing spring, one end of the swing spring is connected to the filter plate, and the other end is connected to the mounting plate, a ball is provided in the ball groove, the ball contacts the plurality of electromagnets, a magnetic ring is embedded in the end surface of the mounting plate, the magnetic ring is arranged toward the electromagnet, when the electromagnet is energized, the magnetic poles of two adjacent electromagnets facing one side of the magnetic ring are opposite, the electromagnet with a magnetic pole different from the magnetic pole of the magnetic ring adsorbs the magnetic ring, and the drainage well is provided with a rotating member for driving the filter plate to rotate.

[0012] By adopting the above technical solution, when in use, the distance sensor energizes multiple electromagnets through the control system at the same time. When the magnetism of the electromagnet corresponding to the position of the magnetic ring is the same as that of the magnetic ring, the repulsive force pushes the magnetic ring upward, so that the swing spring is compressed to the limit position, and then the filter plate is pushed upward. At the same time, the operator starts the rotating part, and the rotating part drives the filter plate to rotate. When the magnetism of the electromagnet corresponding to the position of the magnetic ring is different from that of the magnetic ring, the attractive force moves the magnetic ring downward, so that the mounting plate moves quickly toward the direction of the electromagnet, and the swing spring can start the buffering effect. At the same time, the swing spring can pull the filter downward with the movement of the mounting plate, so that the filter plate can be swung and rotated at the same time, and the effect of moving debris on the filter plate is further improved.

[0013] Optionally, the rotating part includes a first motor, a first gear, and a second gear. The first motor is arranged at the bottom of the drainage well. The output shaft of the first motor is coaxially fixedly connected with the first gear. The second gear is fixedly sleeved outside the support rod. The axial length of the first gear is greater than the axial length of the second gear. The first gear is meshed with the second gear.

[0014] By adopting the above technical solution, when in use, the operator starts the first motor, the output shaft of the first motor drives the first gear to rotate, the first gear is engaged with the second gear, and the second gear drives the support rod to rotate. Since the axial length of the first gear is greater than the axial length of the second gear, when the support rod moves up and down, the first gear can always be engaged with the second gear.

[0015] Optionally, the support rod sleeve is provided with a rotating impeller, the rotating impeller is located above the second gear, and the diameter of the rotating impeller is larger than the diameter of the second gear.

[0016] By adopting the above technical solution, when a large amount of rainwater flows through the drainage hole on the filter plate, the rainwater impacts the rotating impeller. The rotation of the rotating impeller drives the support rod to rotate, thereby recovering the kinetic energy of the rainwater, thereby reducing the output power of the first motor and saving energy.

[0018] By adopting the above technical solution, when the support rod rotates, the rotation of the rotating rod drives the first ring to rotate, so that the rolling ball rotates on the bottom wall of the drainage well, reducing the possibility of wear of the support spring.

[0020] By adopting the above technical solution, when the filter plate swings and rotates, the filter plate squeezes the arc plate, the arc plate drives the guide rod to move, the guide rod is inserted into the power box, the power box drives the sealing plate to move, the sealing plate squeezes the water in the power box, a part of the water is pressed out from the prompt tube, and the other part of the water passes through the power tube and is sprayed to the rotating impeller by the water collecting tube, further driving the rotation of the rotating impeller, further reducing the power of the first motor, and at the same time, the water sprayed from the prompt tube forms a small fountain to remind the operator that the device is operating normally;

[0021] When the filter plate returns to a horizontal state, the reset spring resets and the sealing plate moves toward the axis of the drainage well, so that a negative pressure cavity is formed in the power box. Rainwater on the municipal road body is sucked into the negative pressure cavity, speeding up the drainage.

[0022] Optionally, the return spring sleeve is provided with a bellows, one end of the bellows is connected to the arc plate, and the other end is connected to the side wall of the power box, and a dustproof sponge ring is provided between the outer peripheral side wall of the anti-blocking ring and the side wall of the placement groove.

[0044] The implementation principle of a municipal road drainage system in an embodiment of the present application is as follows: during heavy rain, a large amount of rainwater mixed with debris accumulates on the filter plate 10, the weight on the filter plate 10 increases, the support spring 7 is compressed, the support rod 5 moves downward, and when the distance sensor 9 measures that the distance from the bottom surface of the sliding rod 4 to the sensing end of the distance sensor 9 reaches a threshold, the distance sensor 9 starts the electromagnet 13 through the control system.

When the magnetism of the electromagnet 13 corresponding to the position of the magnetic ring 18 is the same as that of the magnetic ring 18, the repulsive force pushes the magnetic ring 18 upward, so that the swing spring 39 is compressed to the limit position, and then the filter plate 10 is pushed upward. When the magnetism of the electromagnet 13 corresponding to the position of the magnetic ring 18 is different from that of the magnetic ring 18, the attractive force moves the magnetic ring 18 downward, so that the mounting plate 16 moves quickly toward the direction of the electromagnet 13, and the swing spring 39 can play a buffering role.

[0046] Therefore, the filter plate 10 is realized to rotate while swinging, the filter plate 10 squeezes the arc plate 27, the arc plate 27 drives the guide rod 37 to move, the guide rod 37 is inserted into the power box 23, the power box 23 drives the sealing plate 33 to move, the sealing plate 33 squeezes the water in the power box 23, a part of the water is pressed out from the prompt pipe 28, and the other part of the water passes through the power pipe 31 and is then sprayed to the rotating impeller 38 by the water collecting pipe 32, and cooperates with the rainwater directly falling from the drainage hole 12 on the filter plate 10, further driving the rotation of the rotating impeller 38, further reducing the power of the first motor 19, and at the same time, the water sprayed from the prompt pipe 28 forms a small fountain to remind the operator that the device is operating normally;

[0047] When the filter plate 10 returns to a horizontal state, the reset spring 26 is reset, and the sealing plate 33 moves toward the axis of the drainage well 2, so that a negative pressure chamber is formed in the power box 23, and rainwater on the municipal road body 1 is sucked into the negative pressure chamber, thereby accelerating the drainage speed.
