Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a cleaning diameter adjustment structure for a steel pipe inner wall cleaning device. Background Technology

[0002] After a period of use, water pipes will accumulate sediment on their inner walls. To prevent these sediments from clogging the pipes, cleaning devices are needed to clean the inner walls. Traditional cleaning devices have a fixed cleaning diameter and cannot adjust the distance between the cleaning structure and the inner wall of the pipe to accommodate different pipe diameters.

[0003] To address this issue, Chinese utility model patent CN217911991U discloses a pipe inner wall cleaning device. This solution utilizes an adjustment assembly consisting of a guide squeezing ring, a support shaft, a collar hinge rod, a limiting fixing plate, a sliding support plate, and a connecting collar block. When the guide squeezing ring moves, it works in conjunction with the collar hinge rod to move the connecting collar block and the sliding support plate along the inside of the guide frame, allowing the four arc-shaped linkage plates to be adjusted to match the pipe diameter. However, this technical solution still has drawbacks: each time it is used, the operator needs to adjust the expansion diameter of the four arc-shaped linkage plates according to the pipe's inner diameter to ensure contact between the four arc-shaped linkage plates and the pipe's inner wall, making the operation cumbersome and inefficient. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a cleaning diameter adjustment structure for a steel pipe inner wall cleaning device, so as to solve the technical problem that the existing pipe inner wall cleaning devices need to be adjusted automatically when adjusting the cleaning diameter, thus resulting in low efficiency.

[0005] To achieve the above objectives, this utility model provides a cleaning diameter adjustment structure for a steel pipe inner wall cleaning device, comprising:

[0006] The top plate whose rotation center is connected to the power source output end;

[0007] and at least one cleaning assembly disposed on the top plate for cleaning the inner wall of the steel pipe, the cleaning assembly comprising:

[0008] A bracket with a through slot;

[0009] A slide rod with one end slidably engaged with the through groove;

[0010] A cleaning component connected to the other end of the slide rod and used to clean the inner wall of the steel pipe has a gap between the cleaning component and the rotation center of the top plate. In use, the top plate and the support rotate under the drive of the power source, so that the cleaning component deviates from the rotation center along the slide rod axis under centrifugal force and fits against the inner wall of the steel pipe.

[0011] As a preferred technical solution of this utility model, a sleeve is provided at the rotation center of the top plate, the sleeve has an installation groove that matches the shape of the power source output end, and a first positioning hole is provided on the surface of the sleeve.

[0012] As a preferred embodiment of this invention, the cleaning component includes a counterweight and a brush disposed on the surface of the counterweight.

[0013] As a preferred embodiment of this utility model, the top plate is connected to a side wall, and the lower end of the side wall is connected to a bottom plate. The bottom plate, side wall, and top plate together form a chamber for accommodating the cleaning component. The side wall has a through groove that matches the cross-sectional shape of the brush. The cleaning diameter adjustment structure further includes a reset component for retracting the brush into the chamber after the top plate stops rotating.

[0014] As a preferred embodiment of this utility model, the reset component includes:

[0015] A threaded end is provided at one end of the slide rod;

[0016] A nut that mates with the threaded end;

[0017] A pressure ring connected to the nut;

[0018] A spring fitted onto the surface of the slide bar and between the fixing block and the pressure ring.

[0019] As a preferred embodiment of this utility model, the sidewall is provided with a filter nozzle on the side near the through groove, one end of the filter nozzle is formed on a flange, and the flange is in contact with the brush.

[0020] As a preferred embodiment of this utility model, the filter tip is made of an elastic material, and the flange is interference-fitted with the brush.

[0021] As a preferred embodiment of this invention, the cleaning diameter adjustment structure further includes:

[0022] A second positioning hole is formed on the surface of the base plate;

[0023] A fixing block with a third positioning hole is provided on the inner wall of the side wall;

[0024] Bolts that are threadedly connected to the second and third positioning holes.

[0025] The beneficial effects of this utility model are as follows: Under the drive of the power source, the top plate will rotate and generate centrifugal force on the cleaning component. When the centrifugal force overcomes the friction between the slide rod and the through groove on the support surface, the cleaning component will drive the slide rod to expand outward, thereby making the cleaning component fit against the inner wall of the steel pipe. Therefore, by means of centrifugal force, the cleaning component can automatically adapt to pipes with different inner diameters without manual adjustment, which is highly efficient.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0034] like Figure 1 and Figure 2 As shown, a cleaning diameter adjustment structure for a steel pipe inner wall cleaning device includes: a top plate 1 whose rotation center is connected to the output end of a power source; and at least one cleaning component disposed on the top plate 1 for cleaning the inner wall of the steel pipe. The cleaning component includes: a bracket 9 with a through groove 16; a slide rod 15 with one end slidably engaged with the through groove 16; and a cleaning part connected to the other end of the slide rod 15 for cleaning the inner wall of the steel pipe. There is a gap between the cleaning part and the rotation center of the top plate 1. In use, the top plate 1 and the bracket 9 rotate under the drive of the power source, so that the cleaning part deviates from the rotation center along the axial direction of the slide rod 15 under centrifugal force and comes into contact with the inner wall of the steel pipe.

[0035] The above technical solution can automatically adjust the cleaning diameter of the cleaning component. In use, the power source is started so that its output end drives the top plate 1 to rotate. The top plate 1 drives the support 9 to rotate, the support 9 drives the slide rod 15 to rotate, and the slide rod 15 drives the cleaning component to rotate. Since there is a gap between the center of rotation of the cleaning component and the top plate 1, when the top plate 1 rotates, it will generate centrifugal force on the cleaning component. When the centrifugal force overcomes the friction between the slide rod 15 and the through groove 16 on the surface of the support 9, the cleaning component will drive the slide rod 15 to expand outward, so that the cleaning component fits against the inner wall of the steel pipe. As the rotation speed of the top plate 1 increases, the pressure generated by the cleaning component on the inner wall of the pipe also increases, and the cleaning effect is better. Therefore, by means of centrifugal force, the cleaning component can automatically adapt to pipes with different inner diameters without manual adjustment, which is highly efficient. The power source can be a motor or other equivalent equipment.

[0036] like Figure 1 As shown, in this embodiment, a sleeve 2 is provided at the rotation center of the top plate 1. The sleeve 2 has an installation groove that matches the shape of the power source output end, and a first positioning hole 3 is provided on the surface of the sleeve 2.

[0037] The above technical solution can fix the output end of the power source to the top plate 1, and drive the top plate 1 to rotate through the power source, thereby driving the cleaning component to clean the inner wall of the steel pipe.

[0038] like Figure 2 and Figure 3 As shown, in this embodiment, the cleaning component includes a counterweight 10 and a brush 11 disposed on the surface of the counterweight 10.

[0039] The above technical solution can ensure that the brush 11 can contact the inner wall of the steel pipe under the action of centrifugal force. Since a counterweight 10 is provided, when the top plate 1 rotates, it will drive the counterweight 10 to rotate, thereby generating centrifugal force on the counterweight 10, causing the counterweight 10 to expand outward along the axial direction of the slide rod 15, thereby driving the brush 11 to contact the inner wall of the steel pipe.

[0040] like Figure 3 and Figure 4 As shown, in this embodiment, the top plate 1 is connected to a side wall 4, and the lower end of the side wall 4 is connected to a bottom plate 21. The bottom plate 21, the side wall 4, and the top plate 1 together form a chamber for accommodating the cleaning component. The side wall 4 has a through groove 12 that matches the cross-sectional shape of the brush 11. The cleaning diameter adjustment structure also includes a reset assembly for retracting the brush 11 into the chamber after the top plate 1 stops rotating. Specifically, the reset assembly includes a threaded end 17 at one end of the slide rod 15; a nut 18 threadedly engaged with the threaded end 17; a pressure ring 19 connected to the nut 18; and a spring 20 sleeved on the surface of the slide rod 15 and between the fixing block 7 and the pressure ring 19.

[0041] The above technical solution ensures that the brush 11 can automatically retract when not in use, and clean the surface of the brush 11 in the process. When the power source stops running, the top plate 1 stops rotating. Since the counterweight 10 loses centrifugal force, under the elastic action of the spring 20, the spring 20 pushes the pressure ring 19. The pressure ring 19 drives the slide rod 15 to slide along the through groove 16, so that the slide rod 15 drives the counterweight 10 to fit against the bracket 9, thereby driving the brush 11 to retract into the chamber. During the retraction process, the brush 11 rubs against the through groove 12 of the side wall 4, thereby removing the dirt attached to the surface of the brush 11. The dirt is isolated outside the side wall 4, thus automatically cleaning the brush 11.

[0042] like Figure 4 As shown, in this embodiment, a filter nozzle 13 is provided on the side wall 4 near the through groove 16. One end of the filter nozzle 13 is formed on the flange 14, and the flange 14 is in contact with the brush 11. The filter nozzle 13 is made of an elastic material, such as rubber, and the flange 14 and the brush 11 are interference-fitted.

[0043] The above technical solution can better clean the brush 11. Because a filter nozzle 13 is provided, the flange 14 of the filter nozzle 13 is interference-fitted with the brush 11, so that the flange 14 can better clean the dirt on the surface of the brush 11.

[0044] like Figure 2 As shown, in this embodiment, the cleaning diameter adjustment structure further includes: a second positioning hole 5 opened on the surface of the base plate 21; a fixing block 7 with a third positioning hole 8, the fixing block 7 being disposed on the inner wall of the side wall 4; and a bolt 6 threadedly connected to the second positioning hole 5 and the third positioning hole 8.

[0045] The above technical solution facilitates the disassembly of the base plate 21, thereby enabling maintenance of the brush 11 and spring 20 located inside the chamber. When it is necessary to disassemble the base plate 21, use a tool to unscrew the bolts 6 located in the second positioning hole 5 and the third positioning hole 8, thereby opening the chamber. When it is necessary to replace the spring 20 or disassemble the counterweight 10, unscrew the nut 18 located on the surface of the threaded end 17 of one end of the slide rod 15, thereby removing the pressure ring 19 together and removing the spring 20 from the surface of the slide rod 15.

[0046] Working principle: When in use, insert the output end of the power source into the sleeve 2 and use a screw to pass through the first positioning hole 3 to complete the connection between the power source and the device. Start the power source so that its output end drives the top plate 1 to rotate. The top plate 1 drives the bracket 9 to rotate. The bracket 9 drives the slide rod 15 to rotate. When the slide rod 15 rotates, it will drive the counterweight 10 to rotate, thereby generating centrifugal force on the counterweight 10. When the centrifugal force overcomes the elastic force of the spring 20, the counterweight 10 will drive the slide rod 15 to expand outward, so that the brush 11 connected to the counterweight 10 extends out of the groove 12 of the side wall 4. The brush 11 fits against the inner wall of the steel pipe. As the rotation speed of the top plate 1 increases, the pressure generated by the brush 11 on the inner wall of the pipe also increases, and the cleaning effect is better. Therefore, by means of centrifugal force, the brush 11 can automatically adapt to pipes with different inner diameters without manual adjustment, which is highly efficient. The power source can be a motor or other equivalent equipment.

[0047] When the power source stops working, the top plate 1 stops rotating. Since the counterweight 10 loses centrifugal force, under the elastic action of the spring 20, the spring 20 pushes the pressure ring 19. The pressure ring 19 drives the slide rod 15 to slide along the through groove 16, so that the slide rod 15 drives the counterweight 10 to fit against the bracket 9, thereby driving the brush 11 to retract into the chamber. During the retraction process, since a filter nozzle 13 is provided, the flange 14 of the filter nozzle 13 is interference-fitted with the brush 11, so that the flange 14 can isolate the dirt on the surface of the brush 11 to the outside of the side wall 4, thereby automatically cleaning the brush 11.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
