[0016] Figure 3 is a schematic structural diagram of the cleaning brush plate of an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0018] As Figures 1 to 3As shown in the figure, a device for cleaning scale on pipes in a heating and ventilation heat exchange station according to the present utility model includes a driving motor 1. A support rod 2 is connected to the rotating shaft of the driving motor 1. One end of the support rod 2 far from the driving motor 1 is coaxially provided with an adjusting rod 3. An adjustable support sleeve 4 is arranged on the adjusting rod 3 along its length direction. The bottom of a cleaning brush plate 6 is hinged to the support sleeve 4 through a hinged rod 5. The top end of the cleaning brush plate 6 is hinged to the top end of the adjusting rod 3 far from the support sleeve 4 through a hinged rod 5. By adjusting the position of the support sleeve 4 along the length direction of the adjusting rod 3, the state of the hinged rod 5 can be adjusted to realize the outward extension of the cleaning brush plate 6, increase the distance between the cleaning brush plates 6, meet the cleaning requirements of pipes with different diameters, and expand the applicable range of the present utility model. A plurality of cleaning brush plates 6 are arranged at intervals with the adjusting rod 3 as the center. Each cleaning brush plate 6 is provided with cleaning bristles. During use, according to the inner diameter of the pipe to be cleaned, the position of the support sleeve 4 is adjusted to realize the outward extension of the cleaning brush plate 6, so as to ensure that the cleaning bristles contact the inner wall of the pipe during work. After the cleaning brush plate 6 is inserted into the pipe, the driving motor 1 is started to drive the cleaning brush plate 6 to rotate inside the pipe, and the cleaning operation of the inner wall of the pipe can be realized. The structure is simple, the operation is convenient, and the practicability is strong.

[0019] Furthermore, a containing cylinder 7 is arranged at one end of the adjusting rod 3 far from the support rod 2. The cleaning brush plate 6 is arranged between one end of the containing cylinder 7 far from the support sleeve 4 and the support sleeve 4 through a hinged rod 5. A plurality of rows of spray holes 8 are arranged on the containing cylinder 7. A plugging part 9 is elastically arranged in the spray holes 8. The containing cylinder 7 is used to hold cleaning liquid to improve the cleaning effect on the inner wall of the pipe. A liquid adding port can be separately arranged on the containing cylinder 7, or the spray liquid can be added through the spray holes 8, which is specifically set according to actual needs. The elastic arrangement of the plugging part 9 helps the containing cylinder 7 to be thrown out of the spray holes 8 by centrifugal force during rotation, facilitating the spray liquid to be thrown out of the containing cylinder 7 and acting on the inner wall of the pipe. Specifically, a plurality of containing grooves 10 are arranged at intervals outside the containing cylinder 7. Each row of spray holes 8 is arranged in the corresponding containing groove 10. The arrangement of the containing groove 10 can accommodate the plugging part 9 to avoid the situation that the plugging part 9 protrudes too much from the surface of the containing cylinder 7 and collides with the inner wall of the pipe when cleaning a pipe with a smaller inner diameter.

[0020] Preferably, guide holes 11 are provided in the receiving grooves 10 on both sides of the spray hole 8, and guide rods 13 are connected to the guide holes 11 through buffer springs 12, and the guide rods 13 are connected to the blocking part 9; the guide rods 13 can provide guidance for the moving trajectory of the blocking part 9, ensuring that the blocking part 9 can smoothly enter and exit the spray hole 8, wherein when the blocking part 9 is thrown out, the guide rods 13 are not completely separated from the guide holes 11, so as to ensure that the blocking part 9 is smoothly reset later. In addition, during operation, when the blocking part 9 is thrown out due to centrifugal force, the buffer spring 12 is in a stretched state, and the setting of the buffer spring 12 helps to quickly reset the blocking part 9. The blocking part 9 is preferably composed of a cone 9-1 at the bottom and a hemispherical body 9-2 arranged on the cone 9-1; the bottom surface of the hemispherical body 9-2 preferably matches the bottom surface size of the cone 9-1; such a configuration can make the blocking part 9 form a structure with a large outer end and a small inner end, which not only helps the blocking part 9 to be thrown out under the action of centrifugal force, but also helps the thrown cleaning liquid to disperse and flow outward along the tip of the cone 9-1, which can realize the divergence of the sprayed liquid and expand the spraying area. In order to ensure the comprehensiveness of the spraying, the present embodiment preferably arranges the opening positions of the spray holes 8 of two adjacent rows in an alternating state, that is, a non-completely corresponding state.

[0021] In addition, the hemispherical body 9-2 is a hollow structure, in which a weighted ball 9-3 is movably arranged, which helps the centrifugal throwing of the plugging part 9; the spray hole 8 is a cylindrical structure at the bottom and a truncated cone structure at the top, which helps the spray liquid to be dispersed and sprayed outward along the top slope of the spray hole 8 to ensure the spray range. At the same time, it also helps to match the optimized structure of the plugging part 9 to ensure the tightness of the connection between the plugging part 9 and the spray hole 8 in the non-working state.

[0022] Furthermore, in this embodiment, the adjusting rod 3 is preferably set as a threaded rod, the supporting sleeve 4 is threadedly connected to the adjusting rod 3, a sliding sleeve 14 is rotatably provided on the supporting sleeve 4, the sliding sleeve 14 is sleeved outside the adjusting rod 3, and the cleaning brush plate 6 is hingedly provided between the sliding sleeve 14 and the accommodating cylinder 7. When the position state of the cleaning brush plate 6 needs to be adjusted, the supporting sleeve 4 is rotated, and as the supporting sleeve 4 moves along the adjusting rod 3, the hinged rod 5 can be gradually adjusted from an inclined state to a state perpendicular to the adjusting rod 3, so as to increase the spacing between the cleaning brush plates 6; the structure is simple and the operation is easy.

[0023] Furthermore, in this embodiment, a mounting plate 15 is provided on the hinge rod 5, and the cleaning brush plate 6 is elastically arranged on the mounting plate 15; this helps to provide a certain buffer when encountering harder dirt during the working process, avoiding the situation of excessive wear of the cleaning brush caused by rigid contact; preferably, a connecting rod 16 is provided at the bottom of the cleaning brush plate 6, a limiting block 17 is rotatably arranged at the bottom of the connecting rod 16, and a spring 18 fixedly connected to the cleaning brush plate 6 is sleeved outside the connecting rod 16; a through hole for installing the limiting block 17 is provided on the mounting plate 15, and the diameter of the spring 18 is larger than the width of the through hole to ensure that the spring 18 is located above the mounting plate 15 after the cleaning brush plate 6 is connected to the mounting plate 15; when it is necessary to connect the cleaning brush plate 6 to the mounting plate 15, the limiting block 17 can be adjusted to a state corresponding to the through hole, and the cleaning brush plate 6 is pressed down. At this time, the spring 18 is compressed. After the limiting block 17 moves out from the bottom of the through hole, the limiting block 17 is rotated, and the limiting block 17 abuts against the bottom of the mounting plate 15 under the restoring force of the spring 18, which can realize the quick disassembly and assembly of the mounting plate 15 and the cleaning brush plate 6, improving the convenience of subsequent replacement and maintenance.

[0024] Furthermore, in this embodiment, the length of the support rod 2 is adjustable to increase the cleaning stroke and facilitate storage and folding after use to reduce space occupation; specifically, the support rod 2 includes an outer sleeve 2-1, the sleeve 2-1 is connected to the drive motor 1 through a coupling, a support rod 2-2 is slidably arranged in the sleeve 2-1, and at this time, the adjusting rod 3 is arranged at the end of the support rod 2-2; a tapered threaded locking head 19 is arranged at one end of the sleeve 2-1 away from the drive motor 1 for locking and fixing the adjusted support rod 2-2. In addition, a crushing drill bit 20 is arranged at one end of the accommodating cylinder away from the support rod 2. The crushing drill bit 20 helps to break the position where the water scale accumulates thickly in the pipeline along with the drive of the drive motor 1, improving the efficiency and effect of subsequent cleaning.

[0025] When the utility model is in use, first add cleaning liquid into the accommodating cylinder 7, and then adjust the distance between the cleaning brush plates according to the inner diameter of the pipeline to be cleaned. After the adjustment is completed, insert the cleaning brush plate 6 into the pipeline and turn on the drive motor 1; the whole device has a simple structure and is easy to operate, can meet the cleaning operations of pipelines with various diameters, has a wide application range and strong practicability.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
