[0024] By adopting the above technical solution, the device can perform certain cleaning work on the outside of the pipeline through the cooperation of structures such as the pump body 34 and the nozzle 33 when necessary, thereby better meeting the working needs in different situations.

[0025] Specifically, the drying component 32 includes a fan 322, a hose 323, a heating box 324 and an electric heating rod 325. The heating box 324 is installed on the side of the fixed frame 31 away from the pump body 34, multiple fans 322 are installed above the heating box 324, multiple electric heating rods 325 are installed on the inner side of the heating box 324, and the hose 323 is installed on the side of the heating box 324 away from the fixed frame 31.

[0026] By adopting the above technical solution, the device can perform a certain drying process on the pipeline after cleaning through the cooperation of structures such as the fan 322 and the electric heating rod 325, so as to better meet the working needs in different situations.

[0027] Specifically, the drying component 32 further includes a partition net 321 , and the partition net 321 is installed above the fan 322 .

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the clamping and fixing device 7 includes a fixed cylinder 71, an electric telescopic rod 72, a clamping plate 73 and a connecting rod 75. The connecting rod 75 is installed on one side of the connecting column 5 and below the liquid spray cleaning component 8. The fixed cylinder 71 is installed on the side of the connecting rod 75 away from the connecting column 5 and outside the liquid spray cleaning component 8. Clamping plates 73 are provided on the inner side of the fixed cylinder 71 and on the upper and lower sides of the liquid spray cleaning component 8. The fixed cylinder 71 and the two clamping plates 73 are connected by two electric telescopic rods 72.

[0032] By adopting the above technical solution, the device can clamp and fix the pipeline to a certain extent through the cooperation of the electric telescopic rod 72 and the clamping plate 73 when necessary, thereby preventing the pipeline from accidentally moving during the cleaning process.

[0033] Specifically, the clamping and fixing device 7 further includes a rubber layer 74 , and the rubber layer 74 is installed on one side of the clamping plate 73 close to the liquid spray cleaning assembly 8 .

[0034] By adopting the above technical solution, the device can enhance the friction between the clamping plate 73 and the pipe through the rubber layer 74, thereby reducing the possibility of accidental separation of the pipe and the clamping plate 73 and better meeting the work needs.

[0035] When this embodiment is used, when it is necessary to clean the inside of the pipeline, the staff can put the pipeline into the fixing cylinder 71 in the clamping and fixing device 7, and then start the two electric telescopic rods 72 to drive the two clamping plates 73 and the rubber layers 74 thereon to move, and then clamp and fix the pipeline, so as to better meet the working needs in different situations, and the connecting rod 75 plays a role of connection and fixing.

[0036] The structure and principle of the roller assembly 2 composed of a mounting plate, an axle support rod, an axle and a roller, a cylinder lifting seat 4, a motor assembly 6 composed of a chassis, a motor mounting block, a motor, a rotating rod, a bracket, a water gun and a water inlet pipe, and a liquid spray cleaning assembly 8 composed of a first fixed block, a hydraulic telescopic rod, a second fixed block, a cross bar, a telescopic buffer device, a buffer box, a slide plate, a slide bar, a telescopic spring, a cleaning rod, a stabilizing rubber ring, a liquid storage tank, a liquid spray head, a cleaning block and a cleaning brush have been disclosed in a petroleum pipeline cleaning device disclosed in Chinese patent application No. 201820034580.X. The working principle is that when in use, before the motor drives the cross bar and the cleaning brush to rotate to clean the inner wall of the petroleum pipeline, the cleaning liquid inside the liquid storage tank will be sprayed by the liquid spray head. The head sprays onto the inner wall of the oil pipeline. By arranging a cylinder lifting seat, the overall height of the oil pipeline cleaning device is easy to adjust. By fixing the hydraulic telescopic rod through the first fixed block at one end of the rotating rod, the oil pipeline cleaning device is easy to clean oil pipelines of different depths. Through the cooperation of the buffer box, the slide plate, the slide rod, the telescopic spring, the cleaning rod and the cleaning brush, when the motor drives the cross bar to rotate for cleaning, the telescopic spring will shrink under the condition of external pressure, which is convenient for cleaning oil pipelines of different calibers. In summary, the oil pipeline cleaning device is easy to clean oil pipelines of different models and sizes, and has good applicability. After the cleaning is completed, the cleaned paraffin and the remaining paraffin on the cleaning brush are washed away with a water gun to complete the cleaning of the inner wall of the oil pipeline.

[0037] The working principle and use process of the utility model are as follows: when the pipeline anti-corrosion processing needs to use the device to pre-treat the pipeline, the staff pushes the device, moves the device to the working position through the roller assemblies 2 under the bottom plate 1, and connects the pump body 34 in the spray drying device 3 with the external cleaning liquid, and then allows the pipeline to gradually pass through the inner side of the fixed frame 31, starts the pump body 34, and the pump body 34 sends the external cleaning liquid into the side wall of the fixed frame 31, and then the cleaning liquid is sprayed from each nozzle 33 to the outside of the pipeline, thereby spraying and flushing the outside of the pipeline. After the spraying and flushing is completed, the pump body 34 is closed, and then the cylinder lifting seat 4 is operated to adjust the height of the connecting column 5 and the motor assembly 6 and other structures, and then the pipeline is sent to the outside of the spray cleaning assembly 8, and the inner side of the pipeline is cleaned through the cooperation of the motor assembly 6 and the spray cleaning assembly 8. After cleaning, the staff holds the end of the hose 323 in the drying component 32, aligns it with the position of the pipeline that needs to be dried, and starts each fan 322 and each electric heating rod 325. Each fan 322 sends the air filtered by the partition 321 into the heating box 324, and each electric heating rod 325 heats the air. Then the hot air passes through the hose 323 and contacts the pipeline, thereby drying the pipeline. After the pipeline is dried, the pretreatment work is completed; when it is necessary to clean the inside of the pipeline, the staff can send the pipeline into the fixing cylinder 71 in the clamping and fixing device 7, and then start the two electric telescopic rods 72 to drive the two clamps 73 and the rubber layer 74 thereon to move, and then clamp and fix the pipeline, so as to better meet the work needs in different situations. The connecting rod 75 plays a role in connecting and fixing.
