[0015] Compared with the prior art, the present application has the following beneficial effects:

[0018] 3. When the control panel controls the output shaft of the electric telescopic rod b to extend, the four circular drive wheels can contact the outer wall of the water purification plant pipeline; when the control panel controls the two servo motors b to work, the four circular drive wheels can drive the water purification plant pipeline to rotate slowly, realizing the automatic adjustment of the water purification plant pipeline angle.

[0019] 4. The two helical springs a in this invention enable the four circular drive wheels to maintain elastic contact with the water purification plant pipeline under the action of the two helical springs a; the cross mounting bracket provides limiting support for the two movable connecting brackets after resetting, ensuring that there is a certain angle between the two movable connecting brackets after resetting, so that the two movable connecting brackets can only rotate outward at the contact point between the four circular drive wheels and the water purification plant pipeline.

[0020] Furthermore, when the output shaft of the electric telescopic rod b extends under the control panel, the two oil pastels can contact the water purification plant pipe. When the water purification plant pipe rotates under the action of four circular drive wheels, the outer wall of the water purification plant pipe can leave the marks of the two oil pastels, which helps the staff to quickly judge the grinding condition of the weld seam of the water purification plant pipe by looking at the marks of the two oil pastels. The setting of the helical spring b allows the two oil pastels to make elastic contact with the water purification plant pipe, so that the two oil pastels do not need to be replaced frequently.
