[0001] The utility model relates to the technical field of inspection wells, and more specifically, to a municipal inspection well. Background Art

[0002] A large number of underground pipelines are excavated during urban construction, including water pipes, power pipes, etc. These pipes need to have an exit to the ground at intervals. The section from the pipe to the ground is called a manhole. The manhole mouth is closed by a manhole cover. Common materials of the manhole cover include cast iron, reinforced concrete, resin, plastic, fiberglass, composite materials, etc.

[0003] During daily maintenance, workers need to bend over and use a special hook to hook the opening on the manhole cover to open the manhole cover, and then use great force to lift the manhole cover and place it aside. Frequent bending over to do heavy physical work causes great wear and tear on the workers' waist and can easily lead to lumbar muscle strain. Therefore, a structure is needed to solve the problem that workers need to bend over and expend great force to open the manhole cover. Utility Model Content

[0020] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] A municipal inspection well, such as Figures 1 to 5 As shown, it includes a well body 1 and a manhole cover 2 detachably connected to the well body 1. An exit leading to the ground is opened at intervals of the power pipeline. The section from the pipeline to the ground is called a manhole. The part wrapping the surrounding wall of the manhole is regarded as the manhole body 1. A number of reserved through grooves are opened on the side wall of the well body 1. The reserved through grooves allow cables to pass through the well body 1. The manhole cover 2 is clamped on the top surface of the well body 1. Two through holes are opened on the manhole cover 2, which is convenient for the staff to choose to use conventional means to open the manhole cover 2. At the same time, the through holes can balance the air pressure between the inside of the manhole and the outside air to avoid the cold environment under the manhole. This causes inconsistent pressure above and below the manhole cover 2, making it difficult to open the manhole cover 2 from the wellhead. A storage cavity 3 is provided at the side wall position inside the well body 1, and a lifting rod 8 is rotatably connected inside the well body 1. One end of the lifting rod 8 is rotatably connected to the side wall of the storage cavity 3. The lifting rod 8 can rotate around the position where it is rotatably connected to the side wall of the storage cavity 3. The other end of the lifting rod 8 passes through the storage cavity 3 from the inner wall of the well body 1 and is located below the manhole cover 2. When the lifting rod 8 rotates, the lifting rod 8 can lift up the manhole cover 2 to open the manhole cover 2. A pressing rod is slidably connected to the side wall of the storage cavity 3. 4, the lifting rod 8 is transmission-connected with the pressing rod 4, a pressing port 5 communicating with the storage chamber 3 is provided on the top surface of the well body 1, the top surface height of the pressing rod 4 is less than or equal to the top surface height of the pressing port 5, to prevent the pressing rod 4 from penetrating the ground and damaging the flatness of the ground, thus affecting the normal use of the road surface, the staff carries a tool that can be engaged with the pressing rod 4, the tool is engaged with the pressing rod 4 through the pressing port 5, then the staff can grasp the long stick with their hands and apply force downward to drive the pressing rod 4 to slide in the storage chamber 3, the lifting rod 8 rotates with the sliding of the pressing rod 4, and the lifting rod 8 lifts the well cover 2, When the staff presses the pressing rod 4, the end of the lifting rod 8 located under the manhole cover 2 rotates upward and contacts the bottom surface of the manhole cover 2 to lift the manhole cover 2. After the manhole cover 2 is lifted, only a small amount of pressure needs to be applied on one side of the manhole cover 2 to make the manhole cover 2 flip over to the side of the opening of the well body 1, so that the staff can avoid bending over and using greater force to open the manhole cover 2, reducing the force load on the waist of the staff during daily maintenance. In addition, pressing downward to apply force is more labor-saving than pulling upward to further reduce the force used by the staff to open the manhole cover 2.

[0022] like Figures 2 to 3As shown, after the lifting rod 8 is rotated, it abuts against the bottom surface of the manhole cover 2, avoiding the center position of the manhole cover 2, so that after the manhole cover 2 is lifted, the manhole cover 2 is in an unstable state. At this time, the staff only needs to apply a small amount of pressure on one side of the manhole cover 2, and the manhole cover 2 can be tilted and slid to one side under the influence of gravity, so that the manhole cover 2 deviates from the position above the position where it is engaged with the well body 1, preventing the manhole cover 2 from falling and covering the wellhead of the well body 1 again after the staff stops pressing. The length of the part of the pressing rod 4 that passes through the storage cavity 3 is smaller than the diameter of the manhole cover 2, so as to prevent the pressing rod 4 from occupying too much space at the manhole mouth, thereby preventing the pressing rod 4 from hindering the staff from entering the manhole space from the wellhead.

[0023] like Figures 2 to 3 As shown, the lifting rod 8 is connected to the pressing rod 4 through a connecting rod structure, and the connecting rod structure converts the sliding action of the pressing rod 4 into the rotation action of the lifting rod 8. The connecting rod structure is located in the storage chamber 3. The connecting rod structure includes a driven rod 6 rotatably connected to the side wall of the storage chamber 3 and a rotating rod 7 rotatably connected to the side wall of the storage chamber 3. The driven rod 6 is rotatably connected to the rotating rod 7. The driven rod 6 is rotatably connected to the lifting rod 8. The rotating rod 7 is rotated and squeezed by the driven rod 6. The top of the rotating rod 7 rotates toward the position where the lifting rod 8 passes through the storage chamber 3. The lifting rod 8 is rotated and squeezed by the rotating rod 7. The end of the lifting rod 8 away from the rotating rod 7 rotates toward the direction close to the manhole cover 2. The rotating rod 7 and the lifting rod 8 are slidably connected through a control rod 9. The end of the rotating rod 7 close to the lifting rod 8 is fixedly connected to a control rod 9. A sliding groove 10 is provided on the lifting rod 8. The control rod 9 is slidably connected to the sliding groove 10. The control rod 9 rotates with the rotating rod 7 During the process, the side wall of the sliding groove 10 is squeezed, and the lifting rod 8 rotates as the control rod 9 slides. The lifting rod 8 rotates to a position close to the top of the well body 1 as the control rod 9 slides in the sliding groove 10. The driven rod 6 extends the action of the pressing rod 4 to a side closer to the manhole than the position where the rotating rod 7 is rotatably connected to the side wall of the storage chamber 3, driving the end of the rotating rod 7 close to the lifting rod 8 to rotate to a position close to the manhole. During the rotation process, the rotating rod 7 drives the control rod 9 to drive the lifting rod 8 to rotate. The position where the lifting rod 8 is rotatably connected to the side wall of the storage chamber 3 is located above the control rod 9. The distance from the position where the lifting rod 8 is rotatably connected to the side wall of the storage chamber 3 to the inner wall of the well body 1 is less than the distance from the position of the control rod 9 to the inner wall of the well body 1. The end of the lifting rod 8 located below the manhole cover 2 rotates upward and abuts against the bottom surface of the manhole cover 2 to lift the manhole cover 2, so that the connecting rod structure can achieve the effect of converting the sliding action of the pressing rod 4 into the rotation action of the lifting rod 8.

[0024] like Figures 2 to 3As shown, compared with the two sides of the position where the lifting rod 8 is rotatably connected to the inner wall of the storage chamber 3, the length of the lifting rod 8 close to the control rod 9 is smaller than the length of the lifting rod 8 away from the control rod 9. Compared with the two sides of the position where the rotating rod 7 is rotatably connected to the inner wall of the storage chamber 3, the length of the rotating rod 7 away from the control rod 9 is smaller than the length of the rotating rod 7 close to the control rod 9. Through the transmission of the connecting rod structure, a small sliding displacement of the pressing rod 4 can be converted into a larger rotation angle of the lifting rod 8.

[0025] like Figures 2 to 3 As shown, the bottom surface of the driven rod 6 and the bottom surface of the storage chamber 3 are fixedly connected by an elastic member 11, and the elastic member 11 is configured as a spring. The elastic member 11 supports the driven rod 6 at the bottom surface of the driven rod 6, so that sufficient rotation space is left between the driven rod 6 and the bottom surface of the storage chamber 3, and the elastic member 11 can drive the pressing rod 4 to reset upward after the pressing action at the pressing rod 4 is completed. A limiting rod 12 is fixedly connected to the side wall of the storage chamber 3 to prevent the lifting rod 8 from sliding out of the top surface of the well body 1. The elastic force of the elastic member 11 keeps the driven rod 6 in a state of being against the limiting rod 12. At this time, the top end of the pressing rod 4 is located at the pressing port 5, which is convenient for the staff to use tools to engage with the top surface of the pressing rod 4 and perform a pressing operation.

[0026] Working principle:

[0027] The staff engages the tool they carry with the top surface of the pressing rod 4 through the pressing port 5, and the staff applies force to the pressing rod 4 with the help of the tool. The elastic member 11 is compressed by the force, and the driven rod 6 rotates as the pressing rod 4 slides downward in the storage chamber 3, and the driven rod 6 drives the end of the rotating rod 7 close to the control rod 9 to rotate in the direction close to the manhole, and the control rod 9 squeezes the side wall of the sliding groove 10 to push the end of the lifting rod 8 located below the manhole cover 2 to rotate and lift upward. After the manhole cover 2 is lifted by the lifting rod 8, the staff applies pressure on one side of the manhole cover 2. The manhole cover 2 slides away from the position engaged with the well body 1 due to its own gravity. Subsequently, the staff relaxes the pressure on the pressing rod 4, and the elastic member 11 restores its deformation to cause the driven rod 6 to rotate until the top surface of the driven rod 6 is against the limit rod 12, and the pressing rod 4 slides upward to reset. At the same time, the rotating rod 7 and the lifting rod 8 rotate and reset successively. Subsequently, the staff can adjust the position of the manhole cover 2 to fully expose the wellhead part, completing the action of opening the manhole cover 2.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
