Description

Technical Field

[0001] This application relates to the technical field of road flood control and drainage, and particularly to a road flood control and drainage structure. Background Art

[0002] The function of road flood control and drainage is to quickly drain road surface runoff, ground runoff and various urban wastewaters, prevent waterlogging, lower the too-high groundwater level, and drain the water infiltrating into the road structure layer and subgrade, so as to ensure the stability of the subgrade, extend the service life of the road surface, maintain the normal traffic and safety of vehicles and pedestrians, and keep the road clean and hygienic.

[0003] Through retrieval, Chinese Patent Publication No. CN113585435A discloses a municipal road drainage system with an emergency flood control mechanism. In the present invention, an additional pipe is used to form a diversion channel on the side of the sewage channel. Under normal rain conditions, rainwater can enter the transfer water tank and the transition water tank through the additional pipe, and finally enter the sewage channel through the transfer pipe, which has little impact on the overall drainage speed. In case of flood, the driving force can be utilized by the high-speed water flow entering the additional pipe to drive the driving structure. The driving structure consists of two parts: the stirring structure drive and the layered baffle structure drive. When a flood occurs, the stirring structure and the layered baffle structure can be driven respectively.

[0004] Regarding the above related technologies, the inventor found the following defects: when there is a lot of accumulated water, personnel need to open the drainage cover, and at this time, blocking objects need to be placed around the drainage opening. When the blocking objects are small, they are easily washed away by water, and when the blocking objects are large, the total amount makes it inconvenient to move, resulting in the problem of inconvenient occlusion of the drainage opening. Utility Model Content

[0005] In order to facilitate the occlusion of the drainage opening and improve the convenience of use, this application provides a road flood control and drainage structure.

[0006] A road flood control and drainage structure provided by this application adopts the following technical solution: It includes a fixed cylinder, and a plurality of vertical plates are slidably arranged inside the fixed cylinder. The upper ends of the plurality of vertical plates are fixedly connected through a connecting ring. A counterweight box is arranged inside the plurality of vertical plates. The lower ends of the vertical plates are connected to the fixed cylinder through a pull rope, and a fixed shaft is rotatably installed at the upper part of the fixed cylinder, and the pull rope bypasses the fixed shaft.

[0007] Optionally, the plurality of vertical plates are evenly distributed, a chute is arranged on the inner wall of the fixed cylinder, the vertical plates are slidably arranged with the chute, a sleeve is rotatably installed on the fixed shaft, and the pull rope bypasses the sleeve.

[0008] Optionally, a groove is provided at the upper end of the counterweight box, a through hole is provided on the counterweight box, a filter plate is provided at the upper end of the counterweight box, the counterweight box and the filter plate are connected by fixing bolts, and the upper end of the filter plate is inclined.

[0009] Optionally, a limiting groove is provided on the vertical plate, the fixed shaft passes through the limiting groove, and the fixed shaft is slidably arranged in the limiting groove, and the sleeve is arranged inside the vertical plate.

[0010] Optionally, a clamping block is arranged inside the vertical plate, clamping grooves are arranged on both the vertical plate and the fixed cylinder, the clamping block is inserted into the clamping groove, and spring telescopic rods are arranged between both ends of the clamping block and the fixed cylinder.

[0011] Optionally, a limiting block is arranged at the lower part of the vertical plate, and the limiting block is fixedly installed on the vertical plate.

[0012] Optionally, a baffle is arranged inside the counterweight box, a support plate is fixedly installed on the baffle, and the support plate is clamped with the vertical plate.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. By providing components such as a fixed cylinder, a counterweight box, a filter plate, a pull rope, a fixed shaft, a vertical plate, and a connecting ring, in the working process, the fixed cylinder is placed inside the drain outlet. When the drain cover is removed, through the mutual cooperation between the filter plate, the counterweight box, and the pull rope, under the action of the fixed shaft, the vertical plate is driven to move upward, and the vertical plate drives the connecting ring to move accordingly, so as to move the vertical plate and the connecting ring out of the drain outlet and block the drain outlet, playing a protective role. By driving the connecting ring to move downward and placing the drain cover on the connecting ring, the convenient storage of the vertical plate and the connecting ring is realized, achieving the improvement of the practicality of the device.

[0015] 2. By providing components such as a limiting block, a clamping block, and a spring telescopic rod, in the working process, through the mutual cooperation between the clamping block component and the spring telescopic rod component, the connection between the clamping block component and the clamping groove can be maintained, thereby restricting the position of the vertical plate, preventing the vertical plate component and the connecting ring from rising under the action of the counterweight box after the drain cover is opened, which affects the use of the staff, and restricting the descending height of the counterweight box through the limiting block component, achieving the role of supporting the counterweight box and improving the stability of the device.

Detailed implementation manners

[0021] The following further describes the present application in detail with reference to the attached Figures 1 - 4 drawings.

[0022] The embodiment of the present application discloses a road flood control and drainage structure. As Figure 1 , Figure 2 , Figure 3 shown, it includes a fixed cylinder 1, and the fixed cylinder 1 is set in a "T" shape, which is convenient to place the fixed cylinder 1 on the wellhead. A plurality of vertical plates 2 are slidably arranged inside the fixed cylinder 1. A clamping block 12 is arranged inside the vertical plate 2, and clamping grooves 13 are arranged on both the vertical plate 2 and the fixed cylinder 1. The clamping block 12 is inserted into the clamping groove 13. By connecting the clamping block 12 with the clamping groove 13, the position of the vertical plate 2 is restricted to prevent the vertical plate 2 from sliding. The clamping block 12 is pulled by the spring telescopic rod 14 to prevent the clamping block 12 from automatically disengaging from the clamping groove 13, thereby improving the stability of the clamping block 12.

[0023] Please refer to Figure 1 , Figure 2 shown, spring telescopic rods 14 are arranged between both ends of the clamping block 12 and the fixed cylinder 1. The upper ends of the plurality of vertical plates 2 are fixedly connected through a connecting ring 4. By connecting the upper ends of the vertical plates 2 through the connecting ring 4, the stability of the connection of the vertical plates 2 is maintained. A counterweight box 5 is arranged inside the plurality of vertical plates 2, and a limiting block 17 is arranged at the lower part of the vertical plate 2. The descending position of the counterweight box 5 is blocked by the limiting block 17 to prevent the counterweight box 5 from disengaging from the fixed cylinder 1.

[0024] Please refer to Figure 1 , Figure 3 shown, the limiting block 17 is fixedly installed on the vertical plate 2. A baffle 15 is arranged inside the counterweight box 5, and a support plate 16 is fixedly installed on the baffle 15. The support plate 16 is clamped with the vertical plate 2. As the vertical plate 2 moves up and down, the vertical plate 2 drives the support plate 16 and the baffle 15 to move accordingly. The upper opening of the connecting ring 4 is blocked by the baffle 15, thereby improving the safety of use.

[0025] Please refer to Figure 1 ,Figure 4 As shown in the figure, a groove is provided at the upper end of the counterweight box 5, a through hole 6 is provided on the counterweight box 5, and a filter plate 7 is provided at the upper end of the counterweight box 5. Water accumulates and enters the counterweight box 5, thereby increasing the weight of the counterweight box 5. At the same time, the filter plate 7 blocks sundries, thereby preventing sundries from entering the counterweight box 5 and causing blockage of the through hole 6, which affects the automatic weight reduction of the counterweight box 5.

[0026] Please refer to Figure 1 、 Figure 4 As shown in the figure, the counterweight box 5 and the filter plate 7 are connected by fixing bolts. The upper end of the filter plate 7 is inclined, which is convenient for pushing off the sundries accumulated on the filter plate 7 to prevent it from affecting the entry of accumulated water. The lower end of the vertical plate 2 and the fixed cylinder 1 are connected by a pull rope 11. A fixed shaft 8 is rotatably installed on the upper part of the fixed cylinder 1, and the pull rope 11 bypasses the fixed shaft 8. As the counterweight box 5 becomes heavier, one end of the pull rope 11 is driven by the counterweight box 5 to move, and the pull rope 11 drives the vertical plate 2 to rise, thereby automatically pushing the vertical plate 2 and the connecting ring 4 out of the well. As the accumulated water in the counterweight box 5 decreases, the counterweight box 5 automatically reduces its weight, and the vertical plate 2 and the connecting ring 4 automatically descend and automatically retract into the well.

[0027] Please refer to Figure 1 、 Figure 3 As shown in the figure, multiple vertical plates 2 are evenly distributed to maintain the stability of the device and improve the safety of the device. A sliding groove 3 is provided on the inner wall of the fixed cylinder 1, and the vertical plate 2 is slidably arranged in the sliding groove 3. A sleeve 10 is rotatably installed on the fixed shaft 8, and the pull rope 11 bypasses the sleeve 10. While the pull rope 11 moves, the pull rope 11 drives the sleeve 10 to rotate on the fixed shaft 8, thereby reducing the wear of the pull rope 11 and increasing the service life of the pull rope 11.

[0028] Please refer to Figure 1 、 Figure 3 As shown in the figure, a limiting groove 9 is provided on the vertical plate 2, the fixed shaft 8 passes through the limiting groove 9, and the fixed shaft 8 is slidably arranged in the limiting groove 9. While the vertical plate 2 moves, the fixed shaft 8 slides in the limiting groove 9 and restricts the vertical plate 2, thereby improving the stability of the vertical plate 2. The sleeve 10 is arranged inside the vertical plate 2.

[0029] The implementation principle of a road flood control drainage structure in an embodiment of the present application is as follows: when in use, the fixed cylinder 1 is placed inside the drainage well, and then the drainage cover is placed above the fixed cylinder 1. When the water accumulation is serious, the personnel will remove the drainage cover and drive the block 12 to move, thereby separating the block 12 from the slot 13, thereby releasing the restriction on the vertical plate 2. As the amount of water in the counterweight box 5 increases, the counterweight box 5 drives one end of the pull rope 11 to move, and the other end of the pull rope 11 drives the vertical plate 2 to rise, and the vertical plate 2 drives the connecting ring 4 to follow and rise, thereby shielding the drainage cover. As the amount of water entering the inlet decreases, the amount of water flowing through the through hole 6 on the counterweight box 5 is greater than the amount of water flowing in, thereby reducing the weight of the counterweight box 5. At this time, the vertical plate 2 descends under the action of gravity and automatically retracts into the wellhead, and the drainage cover is then covered.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
