DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a boiler pipeline cleaning device, comprising a telescopic cylinder 1, one end of the piston rod of the telescopic cylinder 1 is fixedly connected to a limited drive part 2, the limited drive part 2 comprises an external frame, a drive device is fixedly connected to the external frame, an adjustable limit mechanism is arranged on the outer wall of the external frame, and a cleaning brush head 3 is fixedly connected to one end of the output shaft of the drive device.

[0021] See also Figure 2 Hand-held rods 101 are provided on both side surfaces of the telescopic cylinder 1.

[0022] The hand-held rod 101 is provided to facilitate the user to hold the entire device, thereby improving stability and convenience during use.

[0023] See also Figure 3 to Figure 4 The external frame includes two coaxially arranged and vertically distributed ring bodies 201, the two ring bodies 201 are fixedly connected by a plurality of connecting rods 202 evenly distributed in an annular shape, the driving device is a driving motor 203, and the driving motor 203 is fixedly connected between the plurality of connecting rods 202 through a connecting piece.

[0024] The ring body 201 and the connecting rod 202 constitute the overall frame of the limit drive part 2, which is used to connect the drive motor 203 and the adjustable limit mechanism. The overall frame is a cylindrical structure adapted to the internal structure of the boiler pipeline. The adjustable limit mechanism contacts and supports the inner wall of the pipeline, so that the overall frame is coaxial with the pipeline, thereby ensuring stability during the cleaning process.

[0025] Furthermore, the adjustable limiting mechanism includes a plurality of rotation guide mechanisms whose number and positions correspond one-to-one with the connecting rods 202 and an adjustment mechanism connected to all the rotation guide mechanisms.

[0026] The adjusting mechanism can drive all the rotating guide mechanisms to rotate synchronously and in the same direction independently relative to the overall frame, thereby changing the distance between all the rotating guide mechanisms and the overall frame. It can be adjusted according to boiler pipes of different diameters, so that several rotating guide mechanisms can contact the inner wall of the pipe to provide limiting support for the limit drive part 2 as a whole, and guide it so that it can move inside the pipe along the extension direction of the pipe. The cleaning brush head 3 is driven by the driving motor 203 to clean the inner wall of the pipe, thereby maintaining the stability of the cleaning process.

[0027] Furthermore, each rotary guide mechanism includes a plurality of groups of rotating rods 204 evenly distributed along the extension direction of the connecting rod 202, and each group of rotating rods 204 has two rotating rods. Each group of rotating rods 204 is respectively located on both sides of the corresponding connecting rod 202 and one end is rotatably connected to the outer wall of the connecting rod 202. The other ends of each group of rotating rods 204 are rotatably connected to a limiting roller 205. One ends of all rotating rods 204 located on the same side of the connecting rod 202 are rotatably connected to the surface of one side of the same linkage rod 206. A connecting shaft 207 is also fixedly installed between the opposite side surfaces of a group of rotating rods 204 farthest from the cleaning brush head 3, and the connecting shaft 207 is connected to the adjustment mechanism.

[0028] When the adjusting mechanism drives a corresponding group of rotating rods 204 to rotate independently relative to the connecting rod 202 through the connecting shaft 207, all the rotating rods 204 on the corresponding connecting rod 202 will rotate synchronously in the same direction through the connection of the linkage rod 206, and all the limiting rollers 205 will also be displaced synchronously, so that several groups of limiting rollers 205 can circumferentially contact the inner wall of the pipe to support and guide the whole.

[0029] Furthermore, the adjustment mechanism includes a mounting plate 211, which is fixedly connected to the ring body 201 on the side away from the cleaning brush head 3 through a plurality of fixing rods 212. An adjusting cylinder 210 is fixedly installed at the center position of the surface of one side of the mounting plate 211 facing the ring body 201. A lifting connection member 209 is fixedly installed at one end of the piston rod of the adjusting cylinder 210. The lifting connection member 209 is provided with a plurality of extensions whose number and position correspond one-to-one to the connecting rod 202. The end of each extension is rotatably connected to one end of the adjusting rod 208, and the other end of each adjusting rod 208 is rotatably connected to the corresponding connecting shaft 207.

[0030] The adjusting cylinder 210 drives the lifting connection 209 to move up and down, and at the same time pulls all the connecting shafts 207 through a plurality of adjusting rods 208, so that all the rotating guide mechanisms can be adjusted in angle synchronously, thereby changing the overall outer expansion diameter to fit boiler pipes of different diameters, reducing limitations in use and improving stability during the cleaning process.

[0031] Please participate Figure 1 and Figure 2 The cleaning brush head 3 includes a brush head body, one end of the brush head is fixedly connected to one end of the output shaft of the driving motor 203, and bristles are arranged on the outer wall of the brush head.

[0032] The bristles are made of high-strength wear-resistant material to increase their service life and replacement cycle.

[0033] Working principle: first, insert the limit drive part 2 and the cleaning brush head 3 into the boiler pipe to be cleaned, start the adjusting cylinder 210 to drive the lifting connection part 209 to move, and when all the connecting shafts 207 are pulled to move by the adjusting rod 208, all the rotating rods 204 are opened synchronously to drive the limit roller 205 to fit on the inner wall of the pipe to support and guide the whole, start the telescopic cylinder 1 and the driving motor 203, the telescopic cylinder 1 drives the limit drive part 2 and the cleaning brush head 3 to move along the extension direction of the pipe as a whole, and the driving motor 203 drives the cleaning brush head 3 to rotate to clean the inner wall of the pipe. The limit drive part 2 can support and guide pipes of more pipe diameters, so that the whole device always keeps coaxial with the pipe, avoiding uneven force on the inner wall of the pipe caused by the offset of the whole device and the axial direction of the pipe, affecting the service life of the pipe, thereby improving the stability during the pipe cleaning process and reducing the limitations during use.

[0034] It should be noted that the specific models and specifications of the telescopic cylinder 1, the drive motor 203 and the regulating cylinder 210 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The power supply and principle of the telescopic cylinder 1, the driving motor 203 and the regulating cylinder 210 are clear to those skilled in the art and will not be described in detail here.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
