When the protective cover 6 protects the main box body 4, the protective cover 6 is provided with a mounting hole 7 corresponding to the output port of the main box body 4. The diameter of the mounting hole 7 is larger than the diameter of the output medium bearing section. A mounting ring 8 is arranged on the protective cover 6 and located in the mounting hole 7. A flexible waterproof sleeve 9 is arranged in the mounting ring 8. The waterproof sleeve 9 has good elastic deformation and is made of plastic. The waterproof sleeve 9 is truncated cone-shaped. A rubber sleeve 19 is arranged at the end of the waterproof sleeve 9. The diameter of the rubber sleeve 19 is smaller than the diameter of the mounting ring 8 and is used to sleeve the output medium bearing section.

[0025] When the main box body 4 is moved out of the ground well, the protective cover 6 is sleeved on the main box body 4 along the rise of the main box body 4. When the main box body 4 runs to the highest point, the mounting hole 7 is opposite to the output interface of the main box body 4. At this time, the output medium receiving section is connected to the protective cover 6 from the mounting hole 7 and connected to the corresponding output interface. After the output medium bearing section is inserted into the mounting hole 7, the waterproof sleeve 9 is sleeved on the output medium bearing section. At the same time, the rubber sleeve 19 is in a tightened state and tightened on the output medium bearing section, thereby reducing the gap between the waterproof sleeve 9 and the output medium bearing section, thereby reducing the possibility of rainwater entering the protective cover 6 through the mounting hole 7, thereby reducing the possibility of the main box body 4 being damaged by rainwater, etc.; at the same time, under the action of the protective cover 6, the main box body 4 is protected as a whole, and the main box body 4 is relatively separated from the environment, further reducing the possibility of damage to the main box body 4 and extending the service life of the main box body 4.

The integration part 10 comprises an air pump 101 arranged at the bottom of the main box body 4 and a rubber pad 102 arranged on the rubber sleeve 19. The air inlet end of the air pump 101 is connected to the inside of the ground well, and the air outlet end of the air pump 101 is located in the protective cover 6. The rubber pad 102 is rotatably arranged on the outer end surface of the rubber sleeve 19, and the rubber pad 102 is rotatably covered on the end surface of the rubber sleeve 19 to open and close the waterproof sleeve 9. When the main box body 4 rises, the air pump 101 extracts the air in the ground well and injects it into the protective cover 6, so that the air pressure in the protective cover 6 increases and the waterproof sleeve 9 is pressed out of the protective cover 6. When the main box body 4 descends, the air pump 101 extracts the air in the protective cover 6 and injects it into the ground well, thereby driving the waterproof sleeve 9 to enter the protective cover 6. When the main box body 4 rises to the maximum stroke, start The air pump 101 extracts the gas in the ground well, compresses it and injects it into the protective cover 6. The air pressure in the protective cover 6 increases, and the waterproof cover 9 is pressed out of the protective cover 6, so that it is convenient for the cable, oil pipe or hydraulic pipe to be sleeved in the waterproof cover 9; at the same time, under the action of the air pump 101, the waterproof cover 9 is in an inflated state and the waterproof cover 9 is in a horizontal state, which is further convenient for the installation of the cable, oil pipe or hydraulic pipe; when the main box body 4 runs to the ground well, the air pump 101 is started to inject the gas in the protective cover 6 into the ground towel, so that the waterproof cover 9 enters the protective cover 6, which is convenient for the storage of the protective cover 6; at the same time, when the main box body 4 is working, the waterproof cover 9 that is not connected to the pipeline is opened, and the air pump 101 is started. The air pump 101 injects air into the protective cover 6 and acts on the main box body 4, and the main box body 4 is cooled down, so that the main box body 4 is in the optimal temperature range and the working life of the main box body 4 is extended.

[0028] Reference Figure 2 and Figure 4 Furthermore, in order to facilitate the waterproof cover 9 to be moved out of the protective cover 6 when the air pressure in the protective cover 6 increases, an annular tube 11 is arranged on the main box body 4 and around the output port, and the annular tube 11 is provided with an air outlet facing the protective cover 6. There are multiple air outlets and they are evenly arranged along the circumference of the annular tube 11, and the air outlet faces the waterproof cover 9. An air inlet pipe 12 is arranged on the annular tube 11, and the air inlet pipe 12 is connected to the annular tube 11. The air inlet pipe 12 faces the air pump 101. After the air pump 101 is started, part of the air injected into the protective cover 6 enters the air inlet pipe 12 and the annular tube 11, and is ejected through the air outlet to move the waterproof cover out of the protective cover 6; when the air pump 101 injects air, part of the gas is injected into the annular tube 11 through the air inlet pipe 12, and the gas is ejected from the air outlet to act on the waterproof cover 9 to move the waterproof cover 9 out of the mounting hole 7.

[0029] Reference Figure 2 and Figure 3Furthermore, a plurality of telescopic tubes 13 are provided on the annular tube 11. The telescopic tubes 13 are telescopic structures. The telescopic tubes 13 are hollow and communicated with the air outlet. The length direction and sliding direction of the telescopic tubes 13 are parallel to the axial direction of the annular tube 11. After the air injected into the protective cover 6 enters the annular tube 11, the telescopic tubes 13 are driven to move forward and approach the waterproof cover 9, thereby blowing the waterproof cover 9 out of the protective cover 6. When the gas in the annular tube 11 is passed into the telescopic tubes 13, part of the gas is discharged through the telescopic tubes 13, and the other part of the gas pushes the telescopic tubes 13 to move close to the waterproof cover 9, further facilitating the gas to push the waterproof cover 9 out of the protective cover 6.
