[0027] Working principle: according to the diameter of the pipe to be repaired, the three electric push rods 302 are adjusted to extend at equal distances, so that the diameter of the circle formed in space by the three pulleys 303 matches the inner diameter of the current pipe. The nozzle 201 is inserted into the pipe, and the pulley 303 rolls along the inner wall of the pipe to limit the position, so as to keep the nozzle 201 moving in the same direction as the axis of the pipe. The LED light 208 is kept on to illuminate the inside of the pipe, and the light is fed back to the external computer equipment through the camera 206, so as to achieve the effect of monitoring and viewing the inside of the pipe. Under the illumination of LED light 208, the nozzle 201 can penetrate into the inner distance of the pipe, so as to check the corroded part of the pipe, and then accurately locate the position that needs to be repaired and painted. The crossbeam fits the outside of the pipe mouth, and at the same time, the pipe mouth squeezes the block 603, and the block 603 is pushed against the inner wall of the pipe mouth under the elastic force of spring 1 604, thereby fixing the sliding sleeve 5, pulling the dial block 11, and driving the plate 2 10 away from the paint tube 4 through the push rod 9. At this time, the paint tube 4 can slide within the limit of the inner wall of the sliding sleeve 5. , thereby pushing the nozzle 201 deep into the tube, and the slide rod 602 slides along the slide hole 601, which can effectively limit the ejection trajectory of the block 603, avoiding the problem of misalignment and offset. After positioning, stop sliding the paint tube 4, loosen the shift block 11, and push the plate 2 10 to contact the paint tube 4 under the elastic force of the spring 2 12, and clamp the paint tube 4 on the plate 1 7 to avoid the paint tube 4 shaking and causing the positioning area to deviate. The extended end of the paint tube 4 is connected to the existing external equipment paint pump, so that the paint is sprayed from the nozzle 201 The paint is sprayed out from the spray hole 203, and the spray hole 203 surrounds the inner wall of the pipe, which ensures the uniformity of the spraying. At the same time, it is shielded by each local splash-proof groove 202, which can avoid the paint spraying from colliding with each other and causing random shooting, thereby improving the stability and quality of the spraying. After the spraying is completed, the sliding sleeve 5 is pulled out, and the paint tube 4 is pulled out of the nozzle 201, which is convenient and quick. In this case, the length of the paint tube 4 should be matched according to the actual pipe length and is not limited to a certain length. The paint tube 4 belongs to a common hose material in the prior art and will not be described in detail in this case.
