Technical Field

[0001] The utility model relates to the field of drainage manhole covers for municipal engineering, in particular to a drainage manhole cover which is convenient to lift. Background Art

[0002] As the entrance to urban drainage, manhole covers play an important role in the urban drainage system. A large number of manhole covers are needed to close some lines, drainage pipes, etc. to prevent the external environment from affecting these infrastructures. The existing manhole covers for municipal engineering are cast as integral circular plates, and drainage holes are provided on the manhole covers for drainage. However, when there is a large amount of water on the road, the drainage holes on the manhole covers cannot meet the demand for rapid drainage, resulting in a large amount of water on the road, road obstruction, and affecting people's normal passage.

[0003] After searching, it is found that the Chinese patent "A manhole cover with automatic lifting and drainage" has a publication number of "CN219364880U". In order to solve the above-mentioned problem, the patent uses multiple electrical components such as relays and sensors to lift the manhole cover according to the amount of drainage, so as to quickly drain the water, avoid large amounts of water on the road, and prevent road obstructions, thereby ensuring the normal passage of people. However, the patent uses multiple electrical components, and an additional power supply is required for the device. In addition, short circuits or other faults often occur in electrical equipment, which can easily cause the device to be unable to be used normally.

[0004] Therefore, a drainage manhole cover that is convenient to lift is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage manhole cover that is easy to lift in order to solve the above-mentioned problem, thereby improving the problem that multiple electrical components are used in the patent, an additional power supply is required for the device, and the electrical equipment is prone to malfunction, causing the device to fail to work properly.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions, a drainage manhole cover that is convenient to lift, comprising: a manhole cover; a lifting mechanism, wherein the lifting mechanism is arranged at the bottom end of the manhole cover for lifting the manhole cover; wherein the lifting mechanism includes an auxiliary component, a mounting seat is arranged on the surface of the manhole cover, a water storage seat is fixedly connected to the bottom of the mounting seat, a water inlet is provided at the top of the manhole cover, a metal telescopic tube connected to the water inlet is arranged at the bottom of the manhole cover, a PVC pipe is fixedly connected to the bottom end of the metal telescopic tube, the bottom end of the PVC pipe passes through the mounting seat and the water storage seat in sequence and extends to the inside of the water storage seat, a lifting pipe is fixedly connected to the bottom of the manhole cover, a drain port is provided at the bottom of the water storage seat, the bottom end of the lifting pipe passes through the drain port and is fixedly connected to a blocking seat, a foam board is fixedly connected to the surface of the lifting pipe, and the auxiliary component for resetting the manhole cover is arranged at the bottom end of the blocking seat.

When the water flow on the road surface is large, the water entering the water storage seat through the PVC pipe is difficult to be completely discharged through the drainage outlet in time. At this time, water will accumulate in the water storage seat, and when the water surface contacts the foam board, the foam board will float upward. At this time, the foam board will drive the manhole cover to rise through the lifting pipe, so that the manhole cover can be automatically raised when there is too much water on the road surface, so that the water on the road surface can be discharged in time, and at the same time, the blocking seat can be driven to block the drainage outlet to prevent water leakage at the bottom of the water storage seat from causing the foam board to fall. Subsequently, the accumulated water on the road surface will enter the water storage seat through the gap between the mounting seat and the raised manhole cover, and then fall on the top of the baffle, and finally be discharged into the drainage well through the drainage outlet. Compared with the comparative patent, the present device can realize the lifting of the manhole cover without using any electrical products, and the operation process is stable without short circuit or other faults.

After completing the drainage, the staff promptly uses tools to squeeze the operating rod downward, and the operating rod drives the sealing plate and the blocking rod to withdraw to the outside of the blocking seat, and then the water stored at the bottom of the water storage seat will be discharged through the through hole. As the water level drops, the manhole cover will drive the blocking seat to withdraw to the outside of the drain outlet. As the stored water is completely discharged, the manhole cover will also be reset under the action of its own gravity, so that the manhole cover can be quickly reset to cope with the next drainage and avoid affecting the normal life of pedestrians and vehicles.

[0008] Preferably, a filter element is fixedly connected to the bottom of the manhole cover, an annularly distributed slide groove is opened on the inner wall of the mounting seat, and an annularly distributed slider is fixedly connected to the surface of the filter element, and the slider slides on the inner wall of the slide groove. When the manhole cover is raised, the filter element will drive the movement of the filter element, and the filter element will drive the slider to slide in the slide groove. The filter element can prevent large garbage on the road from entering the mounting seat and causing blockage. At the same time, the coordinated use of the slider and the slide groove can limit the manhole cover to prevent the manhole cover from being offset.

[0009] Preferably, the bottom of the manhole cover is fixedly connected to a telescopic hose sleeved on the surface of the lifting pipe, and the bottom end of the telescopic hose is fixedly connected to the top of the baffle.

An auxiliary component 29 for resetting the manhole cover 1 is arranged at the bottom end of the blocking seat 218. The inner wall of the water storage seat 22 is fixedly connected with a baffle 214. The surface of the water storage seat 22 is provided with a ring The drainage port 217 is arranged in a shaped manner and is located above the baffle 214. When in use, the device is installed in the drainage well through the mounting seat 21. When the water flow on the road surface is small, the water will enter the metal telescopic pipe 24 through the water inlet 210, and then enter the bottom of the water storage seat 22 through the PVC pipe 25, and finally be discharged through the drainage port 28 {the diameter of the drainage port 28 is smaller than the inner diameter of the PVC pipe 25}. When the water flow on the road surface is large, it is difficult for the water entering the water storage seat 22 through the PVC pipe 25 to be completely discharged in time through the drainage port 28. When the water is fully discharged, the water will accumulate in the water storage seat 22. When the water surface contacts the foam board 26, the foam board 26 will float upward. At this time, the foam board 26 will drive the manhole cover 1 to rise through the lifting pipe 23, and at the same time drive the blocking seat 218 to block the drain outlet 28.

As the water level drops, the manhole cover 1 will drive the blocking seat 218 to withdraw to the outside of the drain outlet 28. As the stored water is completely discharged, the manhole cover 1 will also be reset under the action of its own gravity, and then the hook ring is pulled by the tool to make the operating rod 2902 drive the sealing plate 2903 and the blocking rod 2904 to reset.
