Embodiment 1
[0024] An adjustable size cleaning well device, such as Figure 1-7 As shown, it includes a support frame 1, a descending mechanism 2, a clamping mechanism 3 and a rotating expansion mechanism 4. The support frame 1 is provided with a descending mechanism 2, and the descending mechanism 2 is used to clean the inner wall of a water well with different depths, clamp The mechanism 3 is set on the support frame 1, the clamping mechanism 3 is used to clamp the connecting pipe 220 or the extension pipe, the rotating expanding mechanism 4 is arranged on the lowering mechanism 2, and the rotating extending mechanism 4 is used for wells with different sizes of wellheads. The inner wall is cleaned.
[0025] The lowering 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 rod 26, a movable sleeve 27, a first fixed block 28, a first connecting plate 29, and a support rod 210 , rotating shaft 211, first rotating d
Embodiment 2
[0031] On the basis of Example 1, such as Figure 7 As shown, an elastic mechanism 5 is also included, and the elastic mechanism 5 is arranged on the support frame 1. The elastic mechanism 5 is used to loosen the clamped connecting pipe 220 or extension pipe of the device, so that the device can be smoothly installed on the deeper The inner wall of the water well is cleaned, and 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, and a pair of third movable blocks are fixedly connected to one side of the support frame 1. block 51, the third movable block 51 is rotatably connected with a movable rod 52, and the movable rod 52 is used to squeeze the first clamping block 312 to swing in a direction away from each other, so that the first clamping block 312 no longer blocks the pressing rod 37 A third pressure spring 53 is connected between the bottom of one side of the mov
