[0002] The heat exchange tubes in the heat exchanger are used for a long time, and the impurities in the fluid are deposited on the tube wall, which will affect the heat transfer efficiency. Therefore, they need to be cleaned regularly. Due to the slender structure of the heat exchange tubes, it is difficult to clean the center of the tubes with ordinary cleaning, resulting in poor cleaning effect. Although high-pressure gas flushing has a good cleaning effect, the air pipe is frequently inserted into the heat exchange tube and then pulled out, and this is repeated. Not only is the workload large and the efficiency low, but the high-pressure air pipe is easily scratched when inserted into the heat exchange tube, thereby further reducing the cleaning efficiency.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] like Figure 1 As shown, a side door 3 is movably installed on one side of the single-gun cleaning machine, and the bottom of the side door 3 is movably installed on the machine body 1 through a hinge structure, and the two sides of the side door 3 are locked to the outer shell of the machine body 1 through locking screws 4; it is convenient to open the side door 3 for operation; a handle 5 is fixedly installed on the top of the machine body 1 for people to carry; a shoulder strap buckle 6 is fixedly installed on the front and rear ends of the machine body 1 for connecting the shoulder strap, which can facilitate people to carry the cleaning machine for operation and play a labor-saving role.

[0022] like Figure 2 As shown, a pipe inlet 10 is installed at the rear end of the body 1, and the rear protective guide tube 8 is threadedly connected to the pipe inlet 10. A pipe outlet 11 is installed at the front end of the body 1, and the front straight guide tube 7 is threadedly connected to the pipe outlet 11. A front limiter 12 is plugged in the pipe outlet 11 and is held in a fixed position by the front straight guide tube 7.

[0023] like Figure 3As shown, a drive motor 17 is provided at the end of the control handle 2, and is fixedly mounted to the outer shell of the machine body 1 through the drive motor 17. The output end of the drive motor 17 is connected to the drive device 13. A long switch 15 and a round switch 16 are provided on the control handle 2 to control the drive motor 17.

[0024] In this embodiment, the driving device 13 mainly includes a driving wheel 18, a driven wheel 19 and a driving belt 22. The driving wheel 18 and the driven wheel 19 are both rotatably mounted on the inner wall of the body 1, wherein the driving wheel 18 is connected to the output end of the driving motor 17, and the driving belt 22 is sleeved on the driving wheel 18 and the driven wheel 19; the driving device 13 also includes a tensioning wheel 20 and a row of supporting wheels 21. The tensioning wheel 20 is mounted on the inner wall of the body 1 to tension the driving belt 22. The supporting wheel 21 is also mounted on the inner wall of the body 1 and is located above the tensioning wheel 20 to support the driving belt 22, so that the driving belt 22 on the upper part of the driving device 13 remains horizontal and will not be deformed due to the compression of the compression wheel group 25, resulting in insufficient friction.

[0025] In this embodiment, the clamping device 14 mainly includes a tensioning frame 23 and a clamping wheel group 25. The clamping wheel group 25 is movably mounted on the tensioning frame 23 through an axle pin. The rear end of the tensioning frame 23 is movably mounted on the inner wall of the body 1 through a connecting shaft 24. The clamping wheel group 25 is located directly above the driving belt 22.

[0026] In this embodiment, the tensioning adjustment structure 9 mainly includes an adjusting rod 26, a tensioning spring 27, a hand-tightening nut 28 and an adjusting sleeve 30. The bottom of the adjusting rod 26 is connected to the front end of the tensioning frame 23, and the head is installed with a hand-tightening nut 28. The adjusting sleeve 30 is fixed to the top of the outer shell of the body 1. The tensioning spring 27 is sleeved on the adjusting rod 26 and is contained and restricted in the adjusting sleeve 30. After tightening the adjusting rod 26, the tensioning spring 27 sleeved on the outside of the adjusting rod 26 can play a role of elastic compensation to ensure that the clamping wheel group 25 always provides a good clamping force. The upper end of the adjusting rod 26 and the adjusting sleeve 30 are connected by a thread.

[0027] In actual use, first unscrew the locking screw 4 to open the side door 3, and remove the rear protective guide tube 8 and the front straight guide tube 7; then turn the hand nut 28 to loosen the adjusting rod 26, that is, the adjusting rod 26 moves up, and the front end of the tensioning frame 23 moves up, so that the pressing wheel group 25 is out of the state of pressing the driving belt 22, and then the head of the cleaning hose 29 is first passed through the rear protective guide tube 8, and then inserted into the interior through the pipe inlet 10 at the rear end of the body 1, and the cleaning hose 29 is inserted between the driving belt 22 and the pressing wheel group 25, and then the cleaning hose 29 is removed from the outlet pipe. The outlet 11 extends out of the machine body 1 and is finally inserted into the front straight guide tube 7, so that the nozzle of the cleaning hose 29 extends out of the end of the front straight guide tube 7; when passing through the outlet 11, a suitable front limiter 12 is selected according to the diameter of the cleaning hose 29 and inserted into the outlet 11 to limit the cleaning hose 29, thereby avoiding the head of the cleaning hose 29 being retracted into the machine body 1 due to poor control when the cleaning hose 29 is recovered, resulting in failure to extend normally next time; finally, the front straight guide tube 7 and the rear protective guide tube 8 are respectively installed and connected to the outlet 11 and the inlet 10 and tightened. Adjust the position of the cleaning hose 29 so that it is just pressed by the central groove of the pressing wheel group 25, then tighten the adjusting rod 26, drive the head of the tensioning frame 23 to press down, drive the pressing wheel group 25 to press the cleaning hose 29 tightly against the driving belt 22; then press the long switch 15 and the round switch 16 at the same time to test the machine. At this time, the driving motor 17 is controlled to rotate forward, driving the driving belt 22 to rotate forward, and check whether the cleaning hose 29 can be driven to extend forward; similarly, press the long switch 15 alone to check whether the cleaning hose 29 can be retracted normally; after checking that there is no error, close the side door 3 and lock the locking screw 4, and then connect the cleaning hose 29 to the high-pressure gas source to operate. During operation, you only need to lift or carry the machine body 1, insert the head of the front straight guide tube 7 into the heat exchange tube, and then use the long switch 15 and the round switch 16 to control the cleaning hose 29 to extend into the tube for cleaning and retract it after cleaning.
