Description

Technical Field

[0001] This utility model relates to the field of drainage well cover technology, and more specifically, to a rapid drainage well cover device for urban flooding. Background Technology

[0002] Urban flooding is closely related to manhole covers. When the intensity of heavy rainfall exceeds the drainage capacity of underground pipe networks, rainwater can backflow onto the road surface through manholes, exacerbating flooding. At the same time, the rapid flow of water may push up or displace manhole covers, forming dangerous water vortexes that pose a serious threat to road traffic safety. Therefore, ensuring smooth drainage and the stability of manhole covers are key aspects of flood prevention.

[0003] During the laying of underground pipe networks, operators often use drainage manhole covers to install in areas prone to water accumulation. While existing drainage manhole covers have basic drainage functions, their simple structure and slow drainage speed, relying solely on pre-drained holes on their surface, make them inadequate for drainage during heavy rains, leading to significant water accumulation on urban roads. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a rapid drainage well cover device for urban flooding, which has the advantage of rapid drainage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid drainage well cover device for urban flooding, comprising a first cover body, a rectangular plate fixedly connected to the bottom of the first cover body, a motor fixedly connected to the right side of the rectangular plate, a threaded rod fixedly sleeved at the other end of the motor output shaft, the other end of the threaded rod penetrating the rectangular plate and extending into the interior of the rectangular plate and threadedly sleeved with a moving block, the outer surface of the moving block being movably connected to the bottom of the first cover body, a sleeve rod fixedly connected to the outer surface of the moving block, an eccentric rod movably connected to the inner surface of the sleeve rod, a round rod fixedly sleeved inside the eccentric rod, a connecting frame fixedly sleeved on the outer surface of the round rod, a baffle fixedly connected to the outer side of the connecting frame, a sealing plate fixedly connected to the bottom of the first cover body, and the outer surface of the round rod movably sleeved with the inner surface of the sealing plate.

[0006] As a preferred technical solution of this utility model, a first grid mesh is fixedly connected to the outer surface of the first cover, a second cover is fixedly connected to the outer side of the first grid mesh, drainage outlets are evenly opened on the top of the second cover, and the bottom of the second cover is movably connected to the top of the baffle.

[0007] As a preferred embodiment of this utility model, a surface contact water pressure sensor is fixedly connected to the top of the No. 1 cover, and a controller is fixedly connected to the left side of the bottom of the No. 1 cover.

[0008] As a preferred technical solution of this utility model, a built-in power supply is fixedly connected to the right side of the bottom of the No. 1 cover, and the built-in power supply is located directly to the right of the controller.

[0009] As a preferred technical solution of this utility model, a limiting rod is movably sleeved on the inner surface of the second cover, and the other end of the limiting rod passes through the second cover and extends to the outside of the second cover and is fixedly connected to a second grid mesh.

[0010] As a preferred embodiment of this utility model, a buffer ring is fixedly connected to the bottom of the second grid mesh, and the buffer ring is made of rubber.

[0011] As a preferred technical solution of this utility model, a stainless steel buffer pressure spring is movably sleeved on the outer surface of the limiting rod. The bottom of the stainless steel buffer pressure spring is fixedly connected to the top of the second cover body, and the top of the stainless steel buffer pressure spring is fixedly connected to the bottom of the second grid mesh.

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

[0013] 1. This utility model, by setting up a sleeve rod, an eccentric rod, a round rod, a connecting frame, and baffles, allows the surface contact water pressure sensor to send a signal to the controller when the water depth at the top of the first cover is high enough to reach the preset water depth of the surface contact water pressure sensor. The controller then starts the motor, driving the threaded rod to rotate. This causes the moving block to drive the sleeve rod to move horizontally to the left under the limiting action of the first cover. The sleeve rod then squeezes and pushes the eccentric rod, causing the eccentric rod to drive the round rod to start swinging slightly. Finally, the connecting frame drives the eight baffles to swing synchronously, releasing the sealing effect on the drain outlets and allowing the accumulated water to drain into the sewer pipe through the eight drain outlets, achieving a rapid drainage effect with fast response and high drainage efficiency.

[0014] 2. This utility model, by setting a limiting rod, a second grid mesh, a buffer ring, and stainless steel buffer pressure springs, allows the second grid mesh to move vertically downwards when it is run over by a vehicle. This movement overcomes the elastic force of the four stainless steel buffer pressure springs and is limited by the second cover. The stainless steel buffer pressure springs effectively buffer and absorb the severe impact and vibration from the vehicle, dispersing the huge instantaneous pressure and preventing it from being directly transmitted and damaging the surface contact water pressure sensor below. As the second grid mesh continues to move downwards, the buffer ring contacts the first cover, further enhancing the buffering effect. Simultaneously, the second grid mesh intercepts large solid objects, preventing them from directly impacting or accumulating on the sensor surface and blocking the drain outlet and the first grid mesh.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a rapid drainage well cover device for urban flooding, including a first cover body 1. A rectangular plate 3 is fixedly connected to the bottom of the first cover body 1. A motor 4 is fixedly connected to the right side of the rectangular plate 3. A threaded rod 5 is fixedly sleeved at the other end of the output shaft of the motor 4. The other end of the threaded rod 5 passes through the rectangular plate 3 and extends into the interior of the rectangular plate 3, and a moving block 6 is threadedly sleeved thereon. The outer surface of the moving block 6 is movably connected to the bottom of the first cover body 1. A sleeve rod 7 is fixedly connected to the outer surface of the moving block 6. An eccentric rod 8 is movably connected to the inner surface of the sleeve rod 7. A round rod 9 is fixedly sleeved inside the eccentric rod 8. A connecting frame 10 is fixedly sleeved on the outer surface of the round rod 9. A baffle 11 is fixedly connected to the outer side of the connecting frame 10. A sealing plate 12 is fixedly connected to the bottom of the first cover body 1. The outer surface of the round rod 9 is movably sleeved with the inner surface of the sealing plate 12.

[0023] When the motor 4 starts running, it will cause the threaded rod 5 to rotate, which will cause the moving block 6 to drive the sleeve rod 7 to move horizontally to the right under the limiting action of the first cover body 1. The sleeve rod 7 will squeeze and push the eccentric rod 8, causing the eccentric rod 8 to drive the round rod 9 to start swinging slightly. Finally, the connecting frame 10 will drive the eight baffles 11 to swing synchronously.

[0024] Among them, the outer surface of the first cover 1 is fixedly connected to the first grid mesh 15, the outer side of the first grid mesh 15 is fixedly connected to the second cover 16, the top of the second cover 16 is evenly provided with drainage outlets 2, and the bottom of the second cover 16 is movably connected to the top of the baffle 11.

[0025] When the connecting frame 10 drives the baffle 11 to start swinging slightly, the baffle 11 will move to the bottom of the drain outlet 2, thus achieving the sealing effect on the drain outlet 2.

[0026] Among them, a surface contact water pressure sensor 17 is fixedly connected to the top of the No. 1 cover body 1, and a controller 13 is fixedly connected to the left side of the bottom of the No. 1 cover body 1.

[0027] The surface contact water pressure sensor 17 detects a preset water pressure value and sends a signal to the controller 13.

[0028] The bottom right side of the first cover 1 is fixedly connected to the built-in power supply 14, which is located directly to the right of the controller 13.

[0029] The built-in power supply 14 directly supplies power to the motor 4, thus avoiding problems caused by wiring external power sources.

[0030] Among them, the inner surface of the second cover 16 is movably sleeved with a limiting rod 18, and the other end of the limiting rod 18 passes through the second cover 16 and extends to the outside of the second cover 16 and is fixedly connected with a second grid mesh 19.

[0031] The second grid 19 can intercept large solid objects, preventing them from directly impacting or accumulating on the sensor surface and interfering with its normal operation, while also preventing them from clogging the drain outlet 2 and the first grid 15.

[0032] Among them, the bottom of the second grid 19 is fixedly connected to a buffer ring 20, which is made of rubber.

[0033] This design enhances the buffering effect and prevents the second grille 19 from being directly contacted by the surface contact water pressure sensor 17 when it is crushed and moved down by a vehicle, thus preventing damage to the surface contact water pressure sensor 17.

[0034] Among them, a stainless steel buffer pressure spring 21 is movably sleeved on the outer surface of the limiting rod 18. The bottom of the stainless steel buffer pressure spring 21 is fixedly connected to the top of the second cover 16, and the top of the stainless steel buffer pressure spring 21 is fixedly connected to the bottom of the second grid mesh 19.

[0035] Due to the design of the stainless steel buffer pressure spring 21, it can effectively buffer and absorb the severe impact and vibration from the vehicle running over it, disperse the huge instantaneous pressure, and prevent it from being directly transmitted and damaging the surface contact water pressure sensor 17 below.

[0036] Working principle and usage process of this utility model:

[0037] When encountering heavy rain, if the water depth at the top of the No. 1 cover is high, reaching the preset water depth of the surface contact water pressure sensor 17, the surface contact water pressure sensor 17 sends a signal to the controller 13. The controller 13 then starts the motor 4, driving the threaded rod 5 to rotate. This causes the moving block 6 to drive the sleeve rod 7 to move horizontally to the left under the limiting action of the No. 1 cover. The sleeve rod 7 then squeezes and pushes the eccentric rod 8, causing the eccentric rod 8 to drive the round rod 9 to start swinging slightly. Finally, the connecting frame 10 drives the eight baffles 11 to swing synchronously, releasing the sealing effect on the drain outlet 2. This allows the accumulated water to be discharged into the sewer pipe through the eight drain outlets 2, achieving a rapid drainage effect with fast response and high drainage efficiency.

[0038] When the second grid 19 is run over by an external vehicle, it will drive the limiting rod 18 to overcome the elastic force of the four stainless steel buffer pressure springs 21. Under the limiting action of the second cover 16, it will move vertically downward. The stainless steel buffer pressure springs 21 can effectively buffer and absorb the violent impact and vibration from the vehicle, dispersing the huge instantaneous pressure and preventing it from being directly transmitted and damaging the surface contact water pressure sensor 17 below. At the same time, as the second grid 19 continues to move downward, the buffer ring 20 contacts the first cover 1, which can further improve the buffering effect. Meanwhile, the second grid 19 intercepts large solid objects, preventing them from directly impacting or accumulating on the sensor surface and preventing them from clogging the drain outlet 2 and the first grid 15.
