When the upper seat body 41 drives the water inlet pipe 1 to move downward, the upper seat body 41 also moves in the direction of the lower seat body 61. During the descending process of the upper seat body 41, the connecting hook 43 is squeezed by the external inclined surface of the fixed block 64, and the rebound of the fixing mechanism 7 after the pressing down of the hook mounting plate 42 is stopped can drive the upper seat body 41 to move upward through the water inlet pipe 1. At this time, the inner side of the connecting hook 43 is engaged with the bottom of the fixed block 64. When the upper seat body 41 cannot continue to move upward, the upper seat body 41 is pressed down again when the device needs to be disassembled after the work is completed.

When the mounting block 75 is in a fixed state, the outward movement of the horizontal piston 72 can compress the block connecting spring 74.

[0063] During the installation process, when the upper mounting seat 4 drives the water inlet pipe 1 to move downward, during the downward movement of the water inlet pipe 1, the lifting slot 2 opened on the outside of the water inlet pipe 1 can contact the fixing mechanism 7 and drive the vertical piston rod 76 to move downward, and when the vertical piston rod 76 moves downward, it can drive the horizontal piston 72 to move outward, and when the horizontal piston 72 moves outward, it can drive the installation block 75 to expand outward, and when the horizontal piston 72 continues to move outward after the installation block 75 contacts the inner wall of the pipe, the block connecting spring 74 can be contracted, and the block connecting rod 73 can be moved toward the inside of the horizontal piston 72. After the work is completed, the upper mounting seat 4 drives the water inlet pipe 1 to move upward, and when the water inlet pipe 1 moves upward, it can The lifting block 3 inside the lifting slot 2 is engaged with the bottom of the piston connecting plate 77 to drive the vertical piston rod 76 to move upward. When the vertical piston rod 76 moves upward, it can drive the horizontal piston 72 to move toward the inside of the right-angle piston cylinder 71. When the horizontal piston 72 moves toward the inside of the right-angle piston cylinder 71, it can drive the installation block 75 to retract and release the fixation of the position of the lower mounting seat 6. In the process of the upper mounting seat 4 driving the water inlet pipe 1 to move up and down, it can drive the installation block 75 to move to fix and loosen the position of the lower mounting seat 6. In addition, the elastic structure between the installation block 75 and the horizontal piston 72 can still fix the position of the lower mounting seat 6 when a certain deformation occurs on the inner wall of the pipe.

[0064] Embodiment 4:

[0068] When the lower float switch 84 is located in the air, the lower conductive connection seat 845 is below the float counterweight 842, and at this time the lower conductive float 843 is in contact with the lower conductive connection seat 845; when the lower float switch 84 is in a floating state in water, the float counterweight 842 is below the lower conductive connection seat 845, and at this time the lower conductive float 843 is separated from the lower conductive connection seat 845.

[0069] When installing the device, the water inlet pipe 1 moves downward. When the water inlet pipe 1 moves downward, the upper float switch 82 and the lower float switch 84 can be immersed in water. After the upper float switch 82 is immersed in water, the buoyancy drives the upper conductive float 821 and the upper float sleeve 822 to move upward. When the upper conductive float 821 moves upward, the upper conductive float 821 is separated from the upper conductive connecting seat 823. After the lower float switch 84 is immersed in water, the lower float switch 84 floats up. After the lower float switch 84 floats up, a float counterweight 842 is provided below the lower conductive connecting seat 845. At this time, the lower conductive float 843 slides toward the float counterweight 842 and is separated from the lower conductive connecting seat 845. When the water level inside the pipe drops, The position of the upper conductive float 821 drops first. When the position of the upper conductive float 821 drops, the bottom of the upper conductive float 821 can contact the bottom of the upper conductive connecting seat 823. At this time, the connection between the upper conductive float 821 and the upper conductive connecting seat 823 can control the external water inlet to inject water into the pipe. When the water level in the pipe drops too fast, the lower float switch 84 does not contact the water surface. At this time, the float counterweight 842 is above the lower conductive connecting seat 845, and the lower conductive float 843 slides downward and the bottom of the lower conductive float 843 contacts the bottom of the lower conductive connecting seat 845. At this time, the connection between the lower conductive float 843 and the lower conductive connecting seat 845 can increase the amount of water injected into the pipe from the external water inlet.
