[0029] An embodiment of the present invention provides a dewatering well protection device, including an outer sealing plate 1, a connecting member 2 and a sealing member 3. The connecting member 2 includes a sleeve 10, an elastic connecting member 11 and a connecting rod 12. The sleeve 10 is slidably connected to the connecting rod 12. One end of the elastic connecting member 11 is elastically connected to the side end face of the sleeve 10. The outer sealing plate 1 is arranged on the upper end face of the sealing member 3 through the connecting member 2. The sealing member 3 includes an inflatable ring 4, a fixed plate 5, a limiting strip 6, an air nozzle 7, a sealing member 8 and a pump pipe hole 9. The inflatable ring 4 is arranged on the side end face of the fixed plate 5, one end of the limiting strip 6 is fixedly connected to the edge of the upper end face of the fixed plate 5, the air nozzle 7 is arranged on the upper end face of the fixed plate 5, the sealing member 8 is fixedly connected to the upper end face of the fixed plate 5, and the pump pipe hole 9 is opened on the upper end face of the fixed plate 5.

[0030] In this embodiment, the end of the sleeve 10 facing away from the connecting rod 12 is fixedly connected to the lower end face of the outer sealing plate 1, and the end of the connecting rod 12 facing away from the sleeve 10 is fixedly connected to the upper end face of the fixed plate 5. The sleeve 10 and the connecting rod 12 are slidably connected to each other, so that the outer sealing plate 1 and the sealing member 3 are slidably connected to each other through the sleeve 10 and the connecting rod 12. The diameter of the outer sealing plate 1 is larger than the diameter of the precipitation well, and a through hole is opened on the upper end face of the outer sealing plate 1.

[0031] Among them, the elastic connector 11 is elastically connected to the side end face of the connecting rod 12 at one end away from the sleeve 10. The diameters of the two ends of the elastic connector 11 are different, and the diameters of the two ends of the elastic connector 11 are respectively adapted to the sleeve 10 and the connecting rod 12, so that the sleeve 10 and the connecting rod 12 are limited by the elastic connector 11. The sleeve 10 and the connecting rod 12 ensure that the direction of mutual movement between the outer sealing plate 1 and the blocking member 3 is always a vertical line. The elastic connector 11 partially buffers the pressure exerted by the soil accumulated above the blocking member 3, thereby improving the rigid tensile strength of the connector 2. The two ends of the connector 2 are welded to the outer sealing plate 1 and the blocking member 3 respectively. After the blocking member 3 is subjected to the pressure of falling soil, the connection point between the connector 2 and the blocking member 3 is easy to disconnect.

[0032] In this embodiment, the inflatable ring 4 is made of elastic material, the interior of the inflatable ring 4 is hollow, and the interior of the inflatable ring 4 can be inflated. In other embodiments, the inflatable ring 4 can also be the inner tube of a tire. One end of the air nozzle 7 passes through the fixed plate 5 and is connected to the inflatable ring 4. Air can be inflated into the interior of the inflatable ring 4 through the air nozzle 7 to increase the volume of the inflatable ring 4. After expanding and enlarging, the inflatable ring 4 can adapt to precipitation wells of different sizes.

[0033] Furthermore, the limiting strip 6 is arranged outside the inflatable ring 4, and the two ends of the limiting strip 6 are respectively fixedly connected to the top and bottom of the side end surface of the fixing plate 5. The limiting strip 6 is made of elastic material, and the elasticity of the limiting strip 6 is better than the elasticity of the inflatable ring 4. Under the joint action of the fixing plate 5 and the limiting strip 6, the inflatable ring 4 is limited in the middle, and the retractable characteristics of the limiting strip 6 can be stretched as the inflatable ring 4 expands, and the limiting strip 6 also has a certain protective effect on the inflatable ring 4, and the wear resistance of the inflatable ring 4 can be improved at the wrapped position of the limiting strip 6.

[0034] In this embodiment, the seal 8 frames the pump pipe hole 9 inside the upper end surface of the fixing plate 5, wherein the pump pipe hole 9 is used for the passage of the water pumping pipe and the electric wire. The diameter of the pump pipe hole 9 is larger than the common diameter of the water pumping pipe and the electric wire, and the seal 8 can wrap the water pumping pipe and the electric wire therein to prevent soil from passing through the gap between the water pumping pipe and the pump pipe hole 9.

[0035] In this embodiment, the sealing member 8 includes a limiting frame 13 and a blocking ring 14 , and the limiting frame 13 is fixedly connected to a side end surface of the blocking ring 14 .

[0036] Specifically, the blocking ring 14 is made of elastic material, and the diameter from the top to the bottom of the blocking ring 14 first decreases and then increases, and the diameters of the top and bottom of the blocking ring 14 are equal. The structure of the inward-shrinking diameter of the middle of the blocking ring 14 can completely wrap the pumping pipe, and the upper part of the blocking ring 14 is supported by the limit frame 13, so that when the pumping pipe passes through the blocking ring 14, the blocking ring 14 will not be squeezed into the pump pipe hole 9. While ensuring that no fallen soil passes through the pump pipe hole 9 into the precipitation well, the effect of the pumping pipe passing through the blocking ring 14 is better.

[0037] The present invention also provides an application method of a precipitation well protection device. When the precipitation well starts to be emptied, the water pumping pipe and the electric wire are passed through the sealing member 8 and the pump pipe hole 9. After the water pump and the water pipe are lowered into the precipitation well, the sealing member 3 is inserted into the precipitation well and covered on the top of the precipitation well through the outer sealing plate 1. Then, an air pump is used to inflate the inflatable ring 4 through the air nozzle 7, so that the inflatable ring 4 expands and is limited inside the precipitation well. The inflatable ring 4 and the fixed plate 5 are used to prevent the falling soil from entering the precipitation well. Every time the earthwork is excavated to a certain height, the sealing member 3 is lifted through the outer sealing plate 1, the soil on the sealing member 3 is cleared, and the upper precipitation well pipe is cut off. Then the sealing member 3 is placed inside the precipitation well to ensure that the precipitation well will not be blocked by the falling soil during the entire excavation process.

[0038] In summary, the precipitation well protection device provided by the present invention can effectively prevent excavated soil from entering the precipitation well, and effectively prevent the precipitation well from being blocked. The outer sealing plate 1 and the sealing member 3 are connected by the connecting member 2, wherein the sleeve 10 is slidably connected to the connecting rod 12, and the sleeve 10 and the connecting rod 12 are limited by the elastic connecting member 11. When soil falls on the sealing member 3, the elastic connecting member 11 can effectively prevent the connection point between the connecting member 2 and the outer sealing plate 1 and the sealing member 3 from being disconnected, thereby improving the service life of the device. In addition, the inflatable ring 4 is set on the side end surface of the fixing plate 5 through the limiting strip 6, and the inside of the inflatable ring 4 can be inflated through the air nozzle 7 to make the inflatable ring 4 Expansion, and then the size of the diameter of the sealing member 3 can be adjusted, and then the device can adapt to precipitation wells of different sizes; at the same time, a sealing member 8 is arranged on the upper end face of the fixed plate 5, wherein the diameter from the top to the bottom of the blocking ring 14 is first reduced and then increased, and the diameters of the top and bottom of the blocking ring 14 are equal, and the water pumping pipe can be completely wrapped by the structure of the inward shrinkage of the middle diameter of the blocking ring 14, and the upper part of the blocking ring 14 is supported by the limit frame 13, so that the water pumping pipe will not be squeezed into the inside of the pump pipe hole 9 when passing through the blocking ring 14, while ensuring that no fallen soil will pass through the pump pipe hole 9 into the precipitation well, the effect of the water pumping pipe passing through the blocking ring 14 is better.
