Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road drainage, in particular to a municipal road drainage system. Background Art
[0002] The municipal road drainage system is an engineering facility system for treating and draining urban sewage and rainwater. It is an integral part of urban public facilities. The municipal road drainage system planning is an integral part of the city's overall planning. The urban drainage system usually consists of drainage ditches and drainage pipes set in the roadbed. After the rainwater enters the drainage ditches, it is collected by the drainage pipes and discharged into the nearest water body.
[0003] In the case of heavy rainfall, the drainage speed of the drainage device is difficult to meet the needs of removing accumulated water. Water often accumulates in low-lying areas of the road. It is difficult for passing vehicles to judge the depth of the water on the road. If they pass through rashly, they are likely to be submerged by the water and cause damage to the vehicle. Therefore, it is necessary to clean up the water on the road.
[0004] To this end, the utility model with application number 201810035988.3 discloses a water accumulation warning sign for road drainage, including a mounting plate, a mounting frame, a movable part, a fixed part, a telescopic part, a rotating part, a rain shield part and a warning frame; the movable part is fixedly connected to the front side of the mounting plate; the fixed part is fixedly connected to the bottom of the mounting plate, the mounting frame is fixedly connected to the top surface of the mounting plate, and a water outlet is provided on the mounting frame; the telescopic part is clamped with the mounting frame; the rotating part is transmission-connected to the output end of the telescopic part; the warning frame is fixedly connected to the top of the rotating part; and the rain shield part is fixedly connected to the top of the warning frame.
[0005] This solution achieves the effect of facilitating the search for drainage manhole covers covered by accumulated water and facilitating their movement and fixation by setting up movable warning signs, which can remind personnel when clearing accumulated water. However, it uses the method of manually opening the manhole covers for drainage. During the drainage process, vehicles need to stop passing. If the drainage time is long and there are too many vehicles stuck, it is very easy to cause the traffic system to be paralyzed. Utility Model Content
[0006] The purpose of this scheme is to provide a municipal road drainage system to solve the problem of vehicles being unable to pass due to waterlogging on the road.
[0007] In order to achieve the above-mentioned purpose, the present invention provides a municipal road drainage system, including a pavement, a roadbed, a drainage ditch and a drainage pipe, wherein the drainage ditch is arranged in the roadbed, the pavement is fixedly arranged on the upper surface of the roadbed and is provided with a plurality of through holes, the through holes are connected with the drainage ditch, the drainage pipe is connected with the drainage ditch, and also includes a floating block and a drainage cover plate, the floating block is located in the drainage ditch, the drainage cover plate is slidably arranged in the through holes, the drainage cover plate is provided with a plurality of drainage holes, and the floating block is fixedly connected to the drainage cover plate.
[0008] The principle and beneficial effects of this solution are as follows: when there is no water accumulation in the drainage trough, the upper surface of the drainage cover is flush with the road surface and vehicles can pass normally; when the amount of rain is large and the water level in the drainage trough rises, the water in the drainage trough generates buoyancy on the floating block, and the floating block floats up under the buoyancy of the water, thereby driving the drainage cover to float up, and a part of the drainage cover will protrude from the road surface to form a plane higher than the road surface. Vehicles can pass through the drainage cover when passing through this area, thereby avoiding damage to the vehicle caused by wading.
[0009] Furthermore, a plurality of drainage holes are provided on the upper surface and side walls of the drainage cover. When there is no water accumulation in the drainage groove, the drainage cover is flush with the road surface, and the drainage cover drains water through the drainage holes on its upper surface. When the drainage cover rises, it indicates that the water accumulation in the drainage groove increases, and the water accumulation on the road surface may also increase. By also providing drainage holes on the side walls of the drainage cover, the drainage holes on the upper surface and side walls of the drainage cover can drain water at the same time, thereby improving the drainage performance of the drainage cover.
[0010] Furthermore, the upper surface of the drainage cover plate is arc-shaped. Setting the upper surface of the drainage cover plate to an arc shape can effectively reduce the impact on vehicles passing through the drainage cover plate when the road is flooded, making the vehicle pass more smoothly.
[0011] Furthermore, it also includes a lifting barrier and a switch for controlling the lifting of the lifting barrier, wherein the barrier is fixedly arranged on the road surface. When the water on the road surface becomes deeper and the height of the drainage cover plate is no longer sufficient for the normal passage of vehicles, the lifting barrier is raised by controlling the switch to warn passing vehicles that the water on the road surface is too deep and they cannot pass normally; when there is no water on the road surface or the water is less, the switch controls the lifting barrier to descend and vehicles can pass normally.
[0012] Furthermore, it also includes a liquid level sensor, which is fixedly arranged on the inner wall of the drain trough and electrically connected to the switch. By arranging the liquid level sensor, the switch can be automatically controlled to open when the water level in the drain trough rises to the position of the liquid level sensor, without manual control, which is more convenient and quick.
[0013] Furthermore, a mounting column is provided on one side of the roadbed, on which a display screen is fixedly provided for reminding vehicles of waterlogging on the road surface, and the switch is also used to control the start and stop of the display screen; the display screen is a double-sided display screen. When vehicles cannot pass due to waterlogging on the road surface, the display screen can remind passing vehicles, further playing a warning role. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2This is a schematic diagram of the internal structure of the drainage trough according to an embodiment of the utility model. DETAILED DESCRIPTION
[0016] The following is a further detailed description through specific implementation methods:
[0017] The figure marks in the drawings of the specification include: 1. roadbed; 2. road surface; 3. drainage ditch; 4. floating block; 5. drainage cover; 51. drainage hole; 6. lifting barrier; 7. mounting column; 8. display screen; 9. liquid level sensor.
[0018] The embodiment is basically as shown in the attached Figure 1 As shown:
[0019] A municipal road drainage system comprises a roadbed 1, the upper surface of the roadbed 1 is fixed to the road surface 2, a drainage groove 3 is arranged in the roadbed 1, the drainage groove 3 is connected to the drainage pipe, a through hole is opened at the position of the road surface 2 corresponding to the drainage groove 3, and a drainage cover plate 5 is flexibly connected in the through hole. The drainage cover plate 5 is a hollow stainless steel plate with a certain thickness. The specific thickness can be set according to needs. In this scheme, 15 cm is used to reduce the collision between the drainage cover plate 5 and the road surface 2 during the lifting process. A plurality of drainage holes 51 are opened on the upper surface of the drainage cover plate 5. When there is no water accumulation in the drainage groove 3, the upper surface of the drainage cover plate 5 is flush with the road surface 2, and vehicles can pass normally. In order to facilitate the reminder of passing vehicles when the water on the road surface 2 is deep and the vehicle cannot pass, a mounting column 7 is fixed on one side of the road surface 2 through a cement seat, and a display screen 8 is fixed on the mounting column 7 through bolts. In order to meet the requirement of prompting vehicles coming in both directions, the display screen 8 adopts a double-sided LED display screen 8. At the same time, a lifting roadblock 6 is also arranged near the area prone to water accumulation. The specific installation method refers to the existing "anti-collision column" installation method.
[0020] As attached Figure 2 , a plurality of drainage holes 51 are also provided on the side wall of the drainage cover plate 5, thereby improving its drainage performance when the drainage cover plate 5 rises. At the same time, in order to make the vehicle pass through the drainage cover plate 5 more smoothly, the upper surface of the drainage cover plate 5 is set to an arc shape; a floating block 4 is fixed to the lower surface of the drainage cover plate 5 through a connecting rod. The specific floating block 4 can be a plastic floating block 4, which is filled with nitrogen or other gases with lower density. It should be noted that the force generated by the floating block 4 on the drainage cover plate 5 when wading is sufficient to make the drainage cover plate 5 float and support the vehicle to pass instantly; a liquid level sensor 9 is fixed to the inner wall of the drainage trough 3 by bolts for detecting the depth of water accumulation in the drainage trough 3. The liquid level sensor 9 is electrically connected to a switch, which is used to control the lifting and lowering of the lifting barrier 6 and the start and stop of the display screen 8. When in use, when the liquid level sensor 9 senses water accumulation, it transmits a signal to the switch, and the switch controls the lifting barrier 6 to rise, and at the same time turns on the display screen 8 to remind passing vehicles.
[0021] During specific implementation, when there is no water accumulation on the road surface 2, the drainage cover plate 5 is flush with the road surface 2, the lifting barrier 6 is in a lowered state and flush with the road surface 2, and the display screen 8 is in a closed state. At this time, vehicles can pass normally; when the accumulated water in the drainage trough 3 gradually becomes deeper, it means that there may be a small amount of water accumulation on the road surface 2. At this time, the floating block 4 floats up under the buoyancy of the water, driving the drainage cover plate 5 to move up, so that the upper half of the drainage cover plate 5 protrudes from the road surface 2 and is located above the accumulated water. At this time, vehicles can pass through the drainage cover plate 5 without wading; when the accumulated water in the drainage trough 3 further increases, it means that the road surface 2 has been seriously flooded and the height of the drainage cover plate 5 is not enough to support the passage of vehicles. At this time, the liquid level sensor 9 senses the accumulated water and transmits a signal to the switch. The switch controls the lifting barrier 6 to rise, and at the same time controls the display screen 8 to turn on, giving double warnings to passing vehicles.
[0022] The above are only embodiments of the utility model, and the utility model is not limited to the fields involved in this implementation case.

Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
