Description

Technical Field

[0001] The utility model relates to the field of pipeline cleaning, and in particular to a municipal sewage pipe network desilting device. Background Art

[0002] As an important part of urban infrastructure, the operating status of the municipal sewage pipeline network directly affects the urban drainage efficiency and environmental quality. However, with the acceleration of urbanization, the sewage pipeline network faces increasingly serious siltation problems, resulting in pipe blockage and poor water flow, which in turn affects the normal operation of the urban drainage system.

[0003] After searching, the Chinese patent with patent announcement number CN220868417U in the prior art discloses "a sewage pipe network desilting device. The beneficial effect of this utility model is that when the guide cylinder enters the interior of the sewage pipe and is cleaned by the desilting component, the positions of the desilting component and the moving component can be adjusted in advance according to the internal diameter of the sewage pipe. When the desilting component is adjusted, the adjusting screw can be rotated forward to extend to the outside of the connecting sleeve or reversed to retract to the inside of the connecting sleeve, so that the scraper can be pressed against the inner wall of sewage pipes of different diameters, thereby scraping off the silt adhered to the inner wall of the sewage pipe." However, the following defects still exist: :(1) During the cleaning process, since the guide cone and the connecting rod are located in the middle of the guide cylinder, when the sludge on the inner wall of the sewage pipe is removed, the cleaned sludge remains in the sewage pipe due to the obstruction of the guide cone and will not be discharged. Moreover, as the cleaning depth increases, the continuously accumulated sludge will hinder the progress of the device. Although many large pieces of sludge are cleaned from the pipe wall, the sludge is not processed into small pieces, resulting in obstruction of the subsequent water flow impact; (2) The existing dredging device cannot adapt to pipes of different diameters and has poor flexibility; therefore, we make improvements to this and propose a municipal sewage pipe network dredging device. Summary of the Invention

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0026] like Figure 1-5As shown, this embodiment provides a municipal sewage pipe network desilting device, comprising a first frame 1 and a second frame 2, wherein the first frame 1 is located at both ends of the second frame 2, and a cutting assembly 3 is provided on the outer side of one end of the first frame 1 and in the middle of the second frame 2;

[0027] The cutting assembly 3 includes a mounting seat 301, a semicircular scraper 302, a connecting seat 303 and a cross cutter 304. The mounting seat 301 is fixedly set on one side of the first frame 1, and the semicircular scraper 302 is fixedly installed on the mounting seat 301. The two semicircular scrapers 302 can be spliced ​​into a full circle, so that the sludge on the inner wall of the entire pipe can be removed. The connecting seat 303 is fixedly connected to the inner side of the second frame 2, and the cross cutter 304 is installed on the connecting seat 303 by bolts. There are two groups of semicircular scrapers 302 and they are symmetrically arranged. When in use, according to the requirements of the inner diameter of the pipe, semicircular scrapers 302 of different sizes are selected and fixed to the appropriate position of the mounting base 301 by bolts. Under normal circumstances, there is a distance of 5-10mm between the semicircular scraper 302 and the pipe wall, or it directly fits the pipe wall. Under the drive of the equipment, the semicircular scraper 302 can move along the pipe wall to remove the silt on the pipe wall. The cleaned silt is discharged to the outside from the middle of the first frame 1 and the second frame 2. When the silt passes through the cross cutter 304, it will be cut into smaller pieces again to prevent blockage.

[0028] like Figure 2 As shown, a rotating base 4 is fixedly mounted on the first frame 1, and a traveling bracket 5 is rotatably connected to the rotating base 4. A first driving wheel 6 is mounted on the traveling bracket 5 close to the cutting assembly 3, and a second driving wheel 14 is mounted on the traveling bracket 5 away from the cutting assembly 3. When in use, the first driving wheel 6 and the second driving wheel 14 are mounted on the traveling bracket 5 and the first driving wheel 6 and the second driving wheel 14 travel inside the sewage pipe, and the distance between the first driving wheel 6 and the second driving wheel 14 and the center of the first frame 1 is changed by the traveling bracket 5.

[0029] like Figure 4 As shown, a guide rod 7 is fixedly arranged between the first frame 1 and the second frame 2, and a buffer spring 8 and a moving seat 9 are sleeved on the guide rod 7. An intermediate rod 10 is rotatably connected to the moving seat 9, and one end of the intermediate rod 10 is rotatably connected to the middle of the walking bracket 5. When in use, a force close to the guide rod 7 is applied to the walking bracket 5 to make the walking bracket 5 rotate around the rotating seat 4, and the intermediate rod 10 pushes the moving seat 9 to move on the guide rod 7. The buffer spring 8 on the guide rod 7 is used to block and limit the moving seat 9. As the moving seat 9 compresses the buffer spring 8, it provides space for the walking bracket 5 to descend, allowing the first drive wheel 6 and the second drive wheel 14 to move toward the direction close to the guide rod 7, so as to adapt to pipes of different diameters.

[0030] like Figure 1 As shown, the mounting base 301 is symmetrically arranged on the first frame 1, and a reinforcing rod 11 is fixedly connected between the two groups of first frames 1. The two groups of first frames 1 are connected by the reinforcing rod 11 to increase strength.

[0031] like Figure 1 As shown, a lighting system 13 is fixedly installed on one side of the first frame 1. The lighting system 13 adopts digital intelligent control to illuminate the forward direction, which is convenient for observation through external equipment.

[0032] like Figure 1 As shown, the first frame 1, the second frame 2 and the cutting assembly 3 are all made of stainless steel and the device is controlled by an external drive system. A second drive wheel 14 is provided on the end of the first frame 1 away from the first drive wheel 6. The second drive wheel 14 and the first drive wheel 6 are used in conjunction with each other to provide driving power for the whole, thereby realizing the forward operation of the device. At the same time, the overall use of stainless steel material can prevent rust and increase the service life of the device.

[0033] like Figure 1 As shown, three metal shells are installed between the second frame 2 and the two first frames 1 respectively, and three guide rods 7 separate the three metal shells. A cavity is provided inside the metal shell, and a battery and a controller are installed in the cavity. The battery and the controller are electrically connected, and the controller is electrically connected to the motors on the first drive wheel 6 and the second drive wheel 14.

[0034] Specifically, when the sewage pipe network dredging device is working: the device is connected to the external control device by wireless connection or wired connection, and is controlled and driven by the control system of the external device. The overall intelligent control is adopted. According to the requirements of the inner diameter of the pipe, semicircular scrapers 302 of different sizes are selected and fixed to the appropriate position of the mounting seat 301 by bolts, so that the semicircular scraper 302 can fit the pipe wall. Under the drive of the equipment, the semicircular scraper 302 can move along the pipe wall to remove the silt on the pipe wall. The cleaned silt is discharged to the outside from the middle of the first frame 1 and the second frame 2. When the silt passes through the cross cutter 304, it will be cut into smaller pieces again to achieve the purpose of breaking the sludge from the inner wall of the pipe. After the sludge on the pipe wall is cleaned, the broken sludge is flushed out of the pipe by high-pressure water flow.

[0035] To clean pipes of different diameters, the device is directly inserted into pipes of different diameters, and a force is applied to the traveling bracket 5 to approach the guide rod 7, so that the traveling bracket 5 rotates around the rotating base 4, and the intermediate rod 10 pushes the moving base 9 to move on the guide rod 7. The buffer spring on the guide rod 7 plays a blocking and limiting role, so that the first driving wheel 6 and the second driving wheel 14 move toward the guide rod 7 to adapt to pipes of different diameters.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
