[0026] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0027] Example 1

[0028] See also Figures 1 to 6 A rust-proof device for well pipelines for direct drinking of spring water comprises a casing 1, a wheel set 2, a sandblasting machine 4 and a polishing brush 5. The wheel set 2 is connected to the casing 1 and driven by a power device. The power device is connected to the casing 1. The sandblasting machine 4 is connected to the output end of the power device. The polishing brush 5 is arranged on the side of the sandblasting machine 4 away from the wheel set 2. The polishing brush 5 is connected to the output end of the power device. A planetary gear 6 is arranged at the connection between the polishing brush 5 and the power device. The sun gear 61 of the planetary gear 6 is connected to the polishing brush 5, and the inner gear ring 62 is connected to the output end of the power device. According to the internal situation of the pipeline, the polishing brush 5 can also be replaced with other polishing materials.

[0029] like Figure 6 As shown, the connection between the wheel set 2 and the housing 1 is a telescopic structure and is provided with a spring 21.

[0030] like Figure 2 As shown, a first bevel gear 22 is disposed inside the casing 1 , and the first bevel gear 22 is connected to the output end of the power device. A second bevel gear 23 is disposed on the wheel set 2 , and the second bevel gear 23 is meshingly connected with the first bevel gear 22 .

[0031] like Figure 1 As shown, the power device is a reducer 3.

[0032] like Figure 3 and Figure 5 As shown, the sandblasting machine 4 is provided with nozzles 41 in a circumferential array.

[0033] like Figure 6As shown, the wheel set 2 is arranged in a circular array on the housing 1, and the two wheels on the wheel set 2 present an obtuse angle relationship on the side close to the housing 1, and the angle can be set in the range of 120°-160°.

[0034] like Figure 1 and Figure 5 As shown, an emergency traction rope 7 is provided on one end of the housing 1 away from the polishing brush 5 .

[0035] Principle and operation process

[0036] The utility model adopts a reducer 3 to drive the wheel set 2, the sandblaster 4 and the polishing brush 5. The output end of the reducer 3 is directly connected to the sandblaster 4 and the first bevel gear 22, and is connected to the polishing brush 5 through the planetary gear 6. The entire device can be driven by a reducer 3. The telescopic structure and spring 21 between the wheel set 2 and the housing 1 can adapt to different pipe diameters, and provide greater friction between the wheel set 2 and the inner wall of the metal pipe, so as to better ensure the stability of the device operation. The sandblaster 4 utilizes the rotation of the reducer 3 to cooperate with the movement of the wheel set 2, and can remove rust from the inner wall 360°. The polishing brush 5 rotates faster under the action of the planetary gear 6, and can polish the inner wall of the metal pipe after sandblasting, further reducing the contact area between the metal surface and the air or water, and delaying the corrosion time.

[0037] When in use, the device is placed in the pipe in the well, and the position and safety of the device are ensured by the emergency traction rope 7. After reaching the predetermined position, the reducer 3 is started. The reducer 3 drives the wheel set 2 to rotate through the kneading of the first bevel gear 22 and the second bevel gear 23. The device moves in the direction of the emergency traction rope 7 at a constant speed. At the same time, the reducer 3 drives the sandblasting machine 4 to rotate at a constant speed. The nozzle 41 will sandblast the inner wall of the metal pipe. At the same time, the polishing brush 5 rotates at a faster speed under the action of the planetary gear 6, and further polishes the inner wall of the metal pipe. The device continues to move forward and repeats the above process to complete the rust removal and rust prevention of the pipe in the well. When the equipment encounters a fault and stops, the device can be pulled out by dragging the emergency traction rope 7.

[0038] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
