Embodiment 1
[0024] An adjustable size cleaning water well device, such as Figure 1-7 As shown, it includes a supporting frame 1, a lowering mechanism 2, a clamping mechanism 3 and a rotating and expanding mechanism 4. The supporting frame 1 is provided with a lowering mechanism 2, and the lowering mechanism 2 is used to clean the inner walls of water wells of different depths and clamp them. The mechanism 3 is arranged on the support frame 1, the clamping mechanism 3 is used for clamping the connecting pipe 220 or the extension pipe, the rotating and expanding mechanism 4 is arranged on the lowering mechanism 2, and the rotating and expanding mechanism 4 is used for the wellheads of different sizes. Clean the inner wall.
[0025] The descending mechanism 2 includes a sliding plate 21 , a motor shield 22 , a guide rod 23 , a guide sleeve 24 , a first pressure spring 25 , a screw 26 , a movable sleeve 27 , a first fixed block 28 , a first connecting plate 29 , and a support rod 210 , rota...
Embodiment 2
[0031] On the basis of Example 1, as Figure 7 As shown, it also includes an elastic mechanism 5. The elastic mechanism 5 is arranged on the support frame 1. The elastic mechanism 5 is used to make the device loosen the clamped connecting pipe 220 or the extension pipe, so that the device can be smoothly adjusted to deeper The inner wall of the water well is cleaned. The elastic mechanism 5 includes a third movable block 51, a movable rod 52, a third pressure spring 53, a second clamping block 54 and a second tension spring 55. A pair of third movable blocks are fixed on one side of the support frame 1. Block 51, a movable rod 52 is rotatably connected to the third movable block 51, and the movable rod 52 is used to squeeze the first blocking block 312 to swing away from each other, so that the first blocking block 312 is no longer stuck on the pressing rod 37. , a third pressure spring 53 is connected between the bottom of the movable rod 52 and the support frame 1, the third...
