Description

Technical Field

[0001] The utility model relates to the technical field of pipeline desilting, and more specifically, to a pipeline desilting device used in municipal drainage projects. Background Art

[0002] During the routine maintenance of municipal drainage pipes, it is necessary to perform dredging operations inside the pipes, so a pipe dredging device for municipal drainage projects is needed.

The sewage suction pipe 41 is vertically arranged on a walking bracket at the lower end of the mounting seat 1. The collecting box 38 is detachably arranged in the mounting seat 1. The sewage suction pipe 41 is connected to the input end of the sewage pump 39. The output end of the sewage pump 39 is connected to a sewage discharge pipe 40. The sewage discharge pipe 40 is used to transport the silt at the bottom of the pipe extracted by the sewage pump 39 to the collecting box 38. The cleaning mechanism 7 is arranged on the front side of the mounting seat 1, and is used to sweep and clean the inner wall of the pipe.

[0040] Specifically, the mounting base 1 is a rectangular parallelepiped structure, which can be welded by profiles and steel plates, and a hollow structure can be set inside to reduce weight. A travel drive motor can be set on one side of the driving wheel 3 on the travel bracket, and the travel drive motor drives the driving wheel 3 to rotate, so that the driving wheel 3 rotates, thereby driving the pipeline dredging device to move in the pipeline.

[0041] Furthermore, the walking support comprises a driving rod 9 and a U-shaped connecting rod 2, wherein the driving rod 9 is vertically slidably connected to the mounting seat 1, and the driving wheel 3 is arranged at the end of the U-shaped connecting rod 2; Figure 3 and Figure 4 A drive bin 10 is provided in the mounting seat 1, and the drive mechanism 4 is provided in the drive bin 10; the drive mechanism 4 includes a first drive motor 11, a first transmission screw 13, a guide rod 14, a drive block 12 and two transfer rods 15; the guide rod 14 and the first transmission screw 13 are both horizontally fixed in the drive bin 10, the drive block 12 is slidably connected to the guide rod 14, and the drive block 12 is screwed with the first transmission screw 13, the first drive motor 11 is fixed in the drive bin 10, the output shaft of the first drive motor 11 is connected to one end of the first transmission screw, the first ends of the two transfer rods 15 are respectively hinged to the two drive rods 9, and the second ends of the two transfer rods 15 are respectively hinged to the upper and lower ends of the drive block 12.

[0042] Specifically, in the traveling support, the driving rod 9 is fixedly connected to the middle position of the U-shaped connecting rod 2, and the two driving wheels 3 are respectively connected to the two ends of the U-shaped connecting rod 2. When the pipeline desilting device travels in the pipeline, there are two driving wheels 3 arranged at intervals on both sides to support the side wall of the pipeline, and the device is more stable when traveling. Each driving wheel 3 is correspondingly configured with a driving motor (not shown in the figure), which is installed on the corresponding U-shaped connecting rod 2, and the driving motor is connected to the corresponding driving wheel for driving the driving wheel 3 to rotate. By controlling the first driving motor 11 to rotate, the first transmission screw 13 is driven to rotate, and the first transmission screw 13 rotates the driving block 12 to move horizontally. Since the driving block 12 is hinged with the driving rod 9 of the traveling support through the adapter rod 15, the driving block 12 will drive the traveling support to move up and down when it moves, thereby realizing the up and down adjustment of the position of the driving wheel 3, increasing the force between the driving wheel 3 and the inner wall of the pipeline, and improving the stability of the movement of the device. In this embodiment, the driving wheel 3 is made of rubber material. The driving wheel 3 made of rubber material can undergo elastic deformation when subjected to force, thereby better contacting with the inner wall of the pipe, increasing friction, and preventing the driving wheel 3 from slipping.

[0043] Furthermore, the scraping mechanism 5 includes a U-shaped mounting frame 16 and a scraping block 17, the U-shaped mounting frame 16 is fixedly mounted at the end of the U-shaped connecting rod 2 and is located on the outside of the driving wheel 3, and the scraping block 17 is fixedly connected to the open end of the U-shaped mounting frame 16, that is, each U-shaped mounting frame 16 has two driving wheels 3, and the driving wheel 3 is located between the corresponding two scraping blocks 17. In specific implementation, the scraper block 17 is made of a material with certain toughness and elasticity, such as an elastic steel plate or a plastic plate, so that the scraper block 17 can only be squeezed on the inner wall of the pipeline, thereby scraping off the sludge, and the drive wheel 3 can be exposed and squeezed on the inner wall of the pipeline to generate friction. The scraper block 17 can be made of nylon plastic material, for example, and the front end of the scraper block 17 is designed to be sharp and tilted outwardly, so that the scraper block 17 can only be squeezed on the inner wall of the pipeline, thereby scraping off the sludge, and the drive wheel 3 can be exposed and squeezed on the inner wall of the pipeline to generate friction, so that the sludge on the walking path of the drive wheel 3 can be better scraped. The open ends of the U-shaped mounting frame 16 are all provided with scraper blocks 17, so that the device can scrape the sludge on the inner wall of the pipeline when moving forward or backward. Preferably, the scraper block 17 is detachably connected to the U-shaped mounting frame 16 so that it can be disassembled and replaced when worn or damaged, such as being fixedly connected to the U-shaped mounting frame 16 by screws.

[0044] Furthermore, a mounting chamber 37 is provided near the lower end of the mounting seat 1, one side of the mounting chamber 37 penetrates the side wall of the mounting seat 1, and the collecting box 38 can be pulled out and arranged in the mounting chamber 37. With such arrangement, the collecting box 38 for storing sludge in the mounting seat 1 can be turned over and taken out, and the sludge in the collecting box 38 can be dumped. In this embodiment, the sewage pump 39 is installed at the bottom of the mounting seat 1, and the input end of the sewage pump 39 is connected to the sewage pipe 41 through the sewage guide hose 42, and the sewage pipe 40 connected to the output end of the sewage pump 39 extends upward to above the top opening of the collecting box 38, so as to transport the pumped sludge into the collecting box 38.

The L-shaped limiting plate 45 is used to abut against the outer side of the draw-out baffle 43 to block and limit the collection box 38. By providing a limiting assembly consisting of the limiting block 44 and the L-shaped limiting plate 45 above the opening of the mounting bin 37, the collection box 38 in the mounting bin 37 can be limited to prevent the collection box 38 from moving, thereby increasing safety during use.

[0046] Further, the cleaning mechanism 7 includes a second drive motor 18, a mounting block 19, a mounting rod 23 and a brush plate 26; wherein, the second drive motor 18 is fixedly mounted at the front end of the mounting seat 1, the mounting block 19 is fixedly connected to the output shaft of the second drive motor 18, the two mounting rods 23 are symmetrically arranged on the outside of the mounting block 19, the brush plate 26 is fixedly connected to the end of the mounting rod 23 away from the mounting block 19, and the brush plate 26 is provided with bristles; the second drive motor 18 can drive the mounting block 19 to rotate, and then the brush plate 26 at the end of the mounting rod 23 is used to sweep and clean the inner wall of the pipeline.

[0047] Furthermore, a rotating disk 34 is fixedly provided at one end of the mounting block 19 close to the second drive motor 18, a rotating ring 35 is fixedly provided at the side of the rotating disk 34 facing the mounting seat 1, an annular rotating groove 36 is provided on the front end surface of the mounting seat 1, and the rotating ring 35 is rotatably arranged in the rotating groove 36. By arranging the rotating disk 34 and the rotating ring 35 on the mounting block 19, the rotating ring 35 is rotatably connected to the rotating groove 36 on the front end surface of the mounting seat 1, which can play a certain supporting role for the mounting block 19, and avoid a large bending moment being applied to the output shaft of the second drive motor 18 due to the heavy mounting block 19 and other structures thereon.

[0048] Furthermore, the mounting block 19 is provided with an adjustment mechanism 8, see Figure 1 , Figure 2 and Figure 5 , the adjusting mechanism 8 includes a third driving motor 33, a second transmission screw 29 and a slider 27; wherein, two slide rails 28 are symmetrically arranged on the outer side of the mounting block 19, one end of the slider 27 is slidably connected to the slide rail 28, and the mounting rod 23 is fixedly arranged on the other end of the slider 27; a rotating warehouse 30 is arranged inside the mounting block 19, the first ends of the two second transmission screws 29 are rotatably connected to one end of the slide rail 28, the second ends of the two second transmission screws 29 are rotatably connected to the mounting block 19, and the second end of the second transmission screw 29 extends into the rotating warehouse 30; the slider 27 is screwed on the second transmission screw 29; a driven bevel gear 31 is fixedly arranged on the second end of the second transmission screw 29, the third driving motor 33 is fixedly arranged in the rotating warehouse 30, and an active bevel gear 32 is fixedly connected to the output shaft of the third driving motor 33, and the active bevel gear 32 is meshed and driven with the driven bevel gears 31 on the two second transmission screws 29.

[0049] Specifically, the slide rail 28 is a groove-shaped structure, the slider 27 is slidably connected in the groove of the slide rail 28, the second transmission screw 29 is also arranged in the groove-shaped structure of the slide rail 28, and the second transmission screw 29 is screwed to the slider 27. When the third drive motor 33 rotates, the active bevel gear 32 on the output shaft of the third drive motor 33 drives the driven bevel gear 31 to rotate, and the second transmission screw 29 rotates to drive the slider 27 to move along the slide rail 28, and then drives the mounting rod 23 to move, so as to adjust the position of the brush plate 26 from the mounting block 19, so that the cleaning mechanism 7 can be suitable for pipes with different diameters.

[0050] Furthermore, a water tank 20 is also provided in the mounting block 19; a water pipe 24 is provided on the mounting rod 23 along its length direction, a nozzle 25 is provided at the end of the water pipe 24 away from the mounting block 19, and the end of the water pipe 24 close to the mounting block 19 is connected to the water tank 20 through a water guide hose 46; a water inlet hole connected to the water tank 20 is provided at the front end of the mounting block 19, and a rotary joint is provided on the water inlet hole, and the rotary joint is connected to the water pump 22 through a water guide hose 21. Through the above arrangement, water is supplied to the water tank 20 through the water pump 22, and then the water is sprayed out through the nozzle 25 at the front end of the water pipe 24, so that the cleaning mechanism 7 can sweep and spray water while cleaning the inner wall of the pipeline through the brush plate 26, which can better improve the cleaning effect.

[0051] The method of using the pipeline desilting device is as follows: first, place the device in the pipeline to be desilted, and drive the first transmission screw 13 to rotate through the first driving motor 11, so that the driving block 12 moves horizontally, and the driving block 12 drives the two driving rods 9 to move outward through the two adapter rods 15 respectively, and the two driving rods 9 drive the two U-shaped connecting rods 2 to move outward, so that the driving wheel 3 is closely connected with the inner wall of the pipeline until the scraping block 17 contacts the inner wall of the pipeline. Then, start the third driving motor 33, so that the third driving motor 33 drives the second transmission screw 29 to rotate through the bevel gear meshing transmission, so that the two sliders 27 drive the two mounting rods 23 to move outward until the bristles of the brush plate 26 contact the inner wall of the pipeline. Next, the water pump 22 is placed in the external water source, the water pump 22 is started, and the driving wheel 3 drives the device to move along the pipeline, and the second driving motor 18 is started to drive the mounting block 19 to rotate, so that the brush plate 26 sweeps the inner wall of the pipeline in a circumferential direction, and the water pump 22 pumps the water into the water tank 20, and then sprays it out from the nozzle 25 through the water pipe 24, thereby improving the pipeline desilting effect. When the device moves, the silt in front and behind the driving wheel 3 is scraped off by the scraping block 17 to prevent the driving wheel 3 from slipping due to the silt. When the device needs to be removed from the pipeline after dredging, the sewage pump 39 is started to suck the sludge remaining at the bottom of the pipeline into the collection box 38 for collection, and there is no need to flush it through a water pipe, which improves efficiency and reduces water resource consumption; when the sludge in the collection box 38 needs to be cleaned, the L-shaped limit plate 45 is pulled upward to move it away from the pull-out baffle 43 to release the limit, and then the collection box 38 is pulled out of the installation bin 37, and the sludge in the collection box 38 can be cleaned.

[0052] In summary, the pipe dredging device for municipal drainage projects provided by the utility model can drive the two walking brackets to move relative to each other to achieve the up and down adjustment of the driving wheel position by arranging a driving mechanism in the mounting seat, thereby increasing the force between the driving wheel and the inner wall of the pipe and improving the stability of the movement of the device; at the same time, the silt before and after the driving wheel can be scraped off by the scraping mechanism to prevent the driving wheel from slipping due to the silt and affecting the normal movement of the device; in addition, by arranging the silt removal mechanism, it is convenient to clean the silt after cleaning, and there is no need to flush it through a water pipe after silting, which not only improves work efficiency but also reduces the consumption of water resources.
