[0054] Example 8

[0055] Combination Figure 1 , Figure 2 and Figure 6 As shown, based on the above embodiments 1, 2, 3, 4, 5, 6 or 7, the water inlet pipe 102 is funnel-shaped and the slot 404 is L-shaped.

[0056] Based on the above structure, the water inlet pipe 102 is made funnel-shaped to facilitate the addition of water to the inside of the water storage tank 101, and the slot 404 is made L-shaped to cooperate with the locking post 405.

[0057] The working principle of this invention is as follows: When a water pressure test is required on a drilled hole, the device is moved above the hole to be tested, the lower end of the connecting pipe 203 is aligned with the hole, and the handle 500 is rotated in the forward direction. The handle 500 drives the worm 302 to rotate. Through the meshing of the worm 302 and the worm wheel 304, and the sleeve relationship between the worm wheel 304 and the screw 303, the worm 302 rotates and drives the screw 303 to rotate. Through the meshing of the screw 303 and the sleeve 305, the screw 303, the mounting plate 105, and the caster 108 move upward. When the caster 108 moves away from the ground, the ground and the lower surface of the base 100 tightly press the sealing ring 204 to seal the hole to be tested. At this time, the hole to be tested can be pressurized. By setting the water injection component 200 and the lifting component 300, the height of the base 100 can be adjusted, so that the device's own weight and the cooperation of the sealing ring 204 can seal the hole to be tested.

[0058] When the filter screen 109 needs cleaning, push the handle 501 downwards. The handle 501 moves the filter screen 109, the locking pin 405, and the compression ring 403 downwards against the elastic force of the spring 402. When the locking pin 405 moves to the bottom of the slot 404, rotate the handle 501 clockwise. When the handle 501 can no longer be rotated, pull the handle 501 upwards to remove the filter screen 109. After cleaning the filter screen 109, align the locking pin 405 with the slot 404 and press the handle 501 downwards. The handle 501... The filter screen 109, the snap-fit ​​post 405, and the compression ring 403 move downward against the elastic force of the spring 402. When the snap-fit ​​post 405 moves to the bottom of the slot 404, the handle 501 is rotated counterclockwise. When the handle 501 can no longer be rotated, the handle 501 is released. At this time, the elastic force of the spring 402 pushes the compression ring 403, the filter screen 109, and the snap-fit ​​post 405 upward, thus snapping the filter screen 109 into place. By setting the snap-fit ​​assembly 400, the filter screen 109 can be quickly installed and removed, and the structure is simple and easy to operate.
