Description

Technical Field

[0001] This utility model relates to the field of pipeline inner wall cleaning technology, specifically an adjustable descaling device for cleaning pipeline inner walls. Background Technology

[0002] Pipelines are widely used in industrial production and daily life. After long-term use, sediment in the fluid will adhere to the inner wall of the pipe, forming dirt that gradually thickens, resulting in a reduction in the inner diameter of the pipe, a decrease in the flow rate, and affecting normal production and life.

[0003] Most descaling devices currently in use are difficult to adjust the scraper position according to the pipe size. During use, this difficulty limits the device's ability to clean only pipes of the same size, resulting in a narrow application range, poor flexibility, and difficulty in disassembling and replacing the scraper. Furthermore, the scraper's descaling effect deteriorates over time, and some scrapers are incompatible with certain pipes, further restricting the device's descaling range and leading to poor descaling performance and a narrow application scope. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable descaling device for cleaning the inner wall of pipes, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable descaling device for cleaning the inner wall of a pipe, comprising a cylinder and a connecting rod, wherein an adjustment and fixing mechanism is provided inside the cylinder, the adjustment and fixing mechanism includes a movable plate, the movable plate is provided inside the cylinder, a movable rod is provided on the inner wall of the cylinder, a top plate is provided at one end of the movable rod, a locking block is provided on the outer wall of the cylinder, and an elastic band is provided at the other end of the movable rod, wherein a locking groove is provided inside the elastic band.

[0006] As a preferred technical solution, the movable plate is provided with a sliding groove inside, and the sliding groove is provided with a sliding rail inside.

[0007] As a preferred technical solution, the outer wall of the slide rail is provided with a slider, and one side of the slider is connected to the outer wall of the cylinder.

[0008] As a preferred technical solution, the slider has a through hole inside, the shape and size of which match the shape and size of the slide rail, and the slider is connected to the slide rail through the through hole.

[0009] As a preferred technical solution, one end of the connecting rod is provided with a scraper, and the number of scrapers is two.

[0010] As a preferred technical solution, a disassembly and replacement mechanism is provided on one side of the movable plate, the disassembly and replacement mechanism includes a mounting plate, and the mounting plate is provided on one side of the movable plate.

[0011] As a preferred technical solution, the number of mounting plates is two, and bolts are provided inside the mounting plates.

[0012] As a preferred technical solution, a nut is provided on the outer wall of the bolt, and a connecting rod is provided on one side of the mounting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by adjusting the setting of the fixing mechanism, can achieve the function of adjusting the position of the scraper according to the size of the pipe. During use, the two scrapers are moved to the appropriate position by moving the moving rod, and then the scraper position is fixed by the groove and the locking block on the elastic band. This can avoid the situation where it is difficult to adjust the position of the scraper according to the size of the pipe, which would result in the descaling device only being able to clean the inner wall of the pipe of the same size. This ensures the flexibility and application range of the descaling device.

[0015] 2. This utility model, through the setting of the disassembly and replacement mechanism, can achieve the function of disassembling and replacing the scraper. During use, the scraper can be disassembled and replaced by the cooperation of bolts and nuts. This can avoid the situation where the scraper is difficult to disassemble and replace, which would lead to a decrease in the descaling effect after a long period of use, and some scrapers are not compatible with some pipes, thus limiting the descaling range of the descaling device. This ensures the descaling effect and applicable range of the descaling device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 , Figure 2 and Figure 5 As shown, the present invention provides the following technical solution, including a cylinder 1 and a connecting rod 4. An adjustment and fixing mechanism 2 is provided inside the cylinder 1. A scraper 5 is provided at one end of the connecting rod 4. There are two scrapers 5. A disassembly and replacement mechanism 3 is provided on one side of the moving plate 201. A connecting rod 4 is provided on one side of the mounting plate 301.

[0024] When this descaling device is needed, the appropriate scraper 5 must first be replaced according to the requirements. The appropriate scraper 5 is replaced according to the requirements through the disassembly and replacement mechanism 3. After the scraper 5 is replaced, the part of the cylinder 1 with the scraper 5 is inserted into the pipe. Then, the position of the scraper 5 needs to be adjusted according to the size of the pipe. The position of the scraper 5 is adjusted according to the size of the pipe through the adjustment and fixing mechanism 2. After adjustment and fixing, the cylinder 1 is rotated so that the cylinder 1 drives the two scrapers 5 to scrape off the dirt on the inner wall of the pipe. Water is then used to clean the inner wall of the pipe to complete the work.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the cylinder 1 is equipped with an adjustment and fixing mechanism 2. The adjustment and fixing mechanism 2 includes a movable plate 201. The cylinder 1 is equipped with a movable rod 202 on its inner wall. One end of the movable rod 202 is equipped with a top plate 203. The outer wall of the cylinder 1 is equipped with a locking block 207. The other end of the movable rod 202 is equipped with an elastic band 208. The elastic band 208 has a slot 209 inside. The movable plate 201 is equipped with a sliding groove 204 inside. The sliding groove 204 is equipped with a slide rail 205 inside. The outer wall of the slide rail 205 is equipped with a slider 206. One side of the slider 206 is connected to the outer wall of the cylinder 1. The slider 206 has a through hole inside. The shape and size of the through hole match the shape and size of the slide rail 205. The slider 206 is connected to the slide rail 205 through the through hole.

[0026] In this process: After replacing the scraper 5, the cylinder 1 with the scraper 5 is inserted into the pipe. The position of the scraper 5 needs to be adjusted according to the size of the pipe. At this time, the moving rod 202 is pressed, which causes the top plate 203 to move. The top plate 203, through its own shape and the shape of the two moving plates 201, moves the two moving plates 201 outward. During the movement, the moving plates 201 move more smoothly and evenly by sliding the slider 206 on the outer wall of the slide rail 205. The moving plates 201 move the scraper 5 to the appropriate position, so that the scraper 5 presses against the inner wall of the pipe. Then, the slot 209 on the elastic band 208 is locked onto the corresponding locking block 207 to fix the position of the scraper 5, thus completing the adjustment and fixing work.

[0027] like Figure 1 and Figure 5 As shown, a disassembly and replacement mechanism 3 is provided on one side of the movable plate 201. The disassembly and replacement mechanism 3 includes a mounting plate 301. There are two mounting plates 301. Bolts 302 are provided inside the mounting plate 301. Nuts 303 are provided on the outer wall of the bolts 302. A connecting rod 4 is provided on one side of the mounting plate 301.

[0028] Specifically: When the descaling device is needed, the appropriate scraper 5 needs to be replaced according to the requirements. At this time, the nut 303 is rotated out from the outer wall of the bolt 302, and then the bolt 302 is pulled out. Then the mounting plate 301 is removed from the moving plate 201, and the scraper 5 is disassembled. Then the mounting plate 301 on the appropriate scraper 5 is attached to the moving plate 201. Then the mounting plate 301 is fixed by the cooperation of the bolt 302 and the nut 303, thereby completing the disassembly and replacement work.

[0029] The working principle of this utility model is as follows: When the descaling device is needed, the appropriate scraper 5 needs to be replaced according to the requirements. At this time, the nut 303 is rotated out from the outer wall of the bolt 302, and then the bolt 302 is pulled out. Then, the mounting plate 301 is removed from the moving plate 201, and the scraper 5 is disassembled. Then, the mounting plate 301 on the appropriate scraper 5 is attached to the moving plate 201, and then the mounting plate 301 is fixed by the cooperation of the bolt 302 and the nut 303, thus completing the disassembly and replacement work. After replacing the scraper 5, the part of the cylinder 1 with the scraper 5 is inserted into the pipe. Then, the position of the scraper 5 needs to be adjusted according to the size of the pipe. At this time, the moving rod 202 is pressed to make the moving rod 202 drive the top Plate 203 begins to move. The top plate 203, through its own shape and the shape of the two moving plates 201, drives the two moving plates 201 to move outward. During the movement, the moving plates 201 move more smoothly and evenly by sliding the slider 206 on the outer wall of the slide rail 205. The moving plates 201 drive the scraper 5 to the appropriate position, so that the scraper 5 presses against the inner wall of the pipe. Then, the slot 209 on the elastic band 208 is locked onto the corresponding block 207 to fix the position of the scraper 5, thus completing the adjustment and fixing work. After adjustment and fixing, the cylinder 1 is rotated so that the cylinder 1 drives the two scrapers 5 to scrape off the dirt on the inner wall of the pipe. Water is then used to clean the inner wall of the pipe, thus completing the work.
