According to the needs of the process flow, it is equipped with corresponding oil pump units and designed and installed into a complete pipeline system to complete the tasks of oil loading and unloading and transfer. In order to ensure the normal use of pipe fittings and extend the service life of pipe fittings, it is usually necessary to clean the dirt on the inner wall of the pipeline during the maintenance process. In order to improve the cleaning efficiency and reduce the labor intensity of the staff, a cleaning machine is usually used to clean the inner wall of the pipeline. However, it still has the following disadvantages in actual use:

By means of a support pipe, a water pipe and an elastic air bag, the utility model solves the problem that when the cleaning machine cleans the inner wall of the pipe fitting, it is difficult to handle relatively complex pipelines by mechanical cleaning, and the cost of cleaning with a large amount of chemical cleaning liquid is high. In order to ensure stable use, the cleaning machine is usually large in size and inconvenient to store.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a cleaning machine for dirt on the inner wall of a pipe, comprising a support pipe, a water pipe and an elastic air bag, wherein four cleaning brushes are arranged at one end of the outer peripheral surface of the support pipe, two moving wheels are arranged at the other end of the outer peripheral surface of the support pipe, a water pipe is penetrated and connected at one end of the support pipe, a spray pipe is penetrated and welded around one end of the water pipe, and an elastic air bag is clamped and fixed at the center of the outer peripheral surface of the support pipe;

[0009] Furthermore, a cleaning motor is clamped and fixed on the inner side of the support tube, a driving roller is rotatably clamped on one end of the cleaning motor, the outer circumference of the support tube penetrates and clamps the driven ring, the outer circumference of the driving roller is meshed with the inner wall of the driven ring, the outer circumference of the driven ring is clamped with four elastic telescopic tubes, and each of the cleaning brushes is clamped on the other end of an elastic telescopic tube relative to the driven ring;

[0010] The cleaning motor can drive the driven ring to rotate, which further drives the cleaning brush to rotate to clean the inner wall of the pipe. A spring is arranged in the elastic telescopic tube, and the cleaning brush can be squeezed against the inner wall of the pipe through the elastic telescopic tube to ensure the cleaning effect.

[0011] Furthermore, two cylinders are clamped on the inner side of the support tube, one end of each cylinder is slidably clamped with a telescopic rod, the other end of the telescopic rod is clamped with a support frame, the moving wheel is rotatably clamped on one side of the support frame, one side of the support frame is clamped with a moving motor, the moving motor is connected to the moving wheel through the support frame, and the telescopic rod is inserted through the outer circumference of the support tube;

[0012] When cleaning the pipe, the cylinder can drive the telescopic rod to extend and retract, and further drive the moving wheel to fit the inner wall of the pipe. A pressure sensor can be set at one end of the support frame. The pressure monitored by the pressure sensor can prevent the telescopic rod from being damaged due to excessive pressure when the cleaner passes through the curved part of the pipe.

[0013] Furthermore, a vent is provided through one end of the support tube, the cleaning brush and the moving wheel are located at both ends of the elastic airbag, and the vent is located at one end of the moving wheel of the support tube;

[0014] By driving the moving wheel to rotate through the moving motor, the cleaning machine can be moved in the pipeline, so that the cleaning machine does not need to be provided with a driving structure outside the pipeline, thereby reducing the size of the cleaning machine and facilitating movement and storage.

[0015] Furthermore, a thread groove is provided at one end of the outer circumference of the water pipe, the thread groove is located at the other end of the water pipe relative to the spray pipe, and a nozzle is inserted through one end of each spray pipe, the nozzle is located at the other end of the spray pipe relative to the water pipe, and the spray pipe is located at the cleaning brush end of the support pipe;

The air inlet is connected to the inner side of the ventilation pipe.

[0018] When cleaning the pipe, the outside air is pumped into the elastic airbag through an air pump, causing it to expand and squeeze against the inner wall of the pipe, thereby improving stability during cleaning. The elastic airbag can also separate the inside of the pipe to prevent the sewage after cleaning from contaminating the cleaned part of the pipe.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that, in order to ensure the stability of the cleaning device during use, the main structure of the cleaning device is usually located outside the pipeline, the device is large in size, and the cleaning and maintenance of the pipe fittings have a certain period. When the device is not needed, it is usually not convenient to store, which reduces the space utilization rate. When the pipeline is regularly cleaned, the cleaning machine is moved to one end of the pipeline. After manually cleaning the one end of the pipeline, the cleaning machine is plugged into the inside of the pipeline, and the moving wheels and the cleaning brush are controlled to squeeze and fit the inner wall of the pipeline. The elastic airbag is inflated to expand and squeeze the inner wall of the pipeline, so that the cleaning machine is stably supported in the pipeline. The cleaning machine can move in the pipeline through the moving wheels and clean, and there is no need to set a driving structure that can stably support it on the outside of the pipeline. The size is small, which is convenient for storage and transportation, and the airbag can separate the inside of the pipeline to prevent the sewage after cleaning from contaminating the cleaned part of the pipeline, thereby improving the cleaning efficiency.

When the cleaning machine moves in the pipe, water or cleaning liquid can be sprayed on the inner wall of the pipe in a regular and quantitative manner through the spray pipe to soften and treat the dirt, and the cleaning brush is rotated in contact with the inner wall of the pipe to clean the pipe, thereby improving the cleaning efficiency, without the need to use a large amount of water or cleaning liquid, and the elastic air bag that can be deformed to a certain extent can enable the cleaning machine to pass through the curved part in the pipe, so that the complex pipe can be cleaned mechanically and chemically without being disassembled, thereby improving the cleaning efficiency.
