[0001] The utility model belongs to the technical field of pipeline cleaning, and in particular relates to a device for cleaning the wall of a building drainage pipe. Background Art

[0002] At present, plastic pipes are mainly used for building water supply and drainage. For example, domestic sewage and rainwater are discharged. Since the water contains a large amount of foreign matter, it is easy to form deposits in the pipes and attach to the inner wall of the pipes, affecting the water supply and drainage. In addition, the attachments on the pipe walls are prone to breed bacteria or insects, especially in summer, which brings inconvenience to people's lives. Therefore, the pipe walls need to be cleaned regularly.

[0003] The existing cleaning methods mainly use manual digging and cleaning robots. Since manual digging is labor-intensive, time-consuming and inconvenient to clean deep locations, cleaning robots have gradually replaced manual work. Although robots are used to clean the inner wall of the pipe, the problems caused by manual cleaning can be solved, but the cleanliness of robots is poorer than that of manual cleaning. When encountering harder and more adhesive debris, it may not be able to clean it more thoroughly. In view of this, the present utility model is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3 The device for desilting the wall of a building drainage pipe comprises a bracket 1, and also comprises: a counterweight block 3 suspended on the bracket 1; a variable speed motor 303 fixedly connected to the lower end of the counterweight block 3; a rotating shaft 304 fixedly connected to the output end of the variable speed motor 303; a cleaning brush 306 arranged at equal intervals on the outside of the rotating shaft 304; a tension telescopic rod 305 symmetrically arranged between the rotating shaft 304 and the cleaning brush 306, and the two ends of the tension telescopic rod 305 are respectively connected to the rotating shaft 304 and the cleaning brush 306. The brush 306 is fixedly connected; one end of the connecting rope 202 is rotatably connected to the counterweight 3; a retractable component for retracting and extending the connecting rope 202 is installed on the bracket 1; the tensioning telescopic rod 301 is fixedly connected to the outside of the counterweight 3 at equidistant intervals in a circle; the telescopic end of the tensioning telescopic rod 301 is fixedly connected to a support, and a roller 302 is rotatably connected to the support; a monitoring component for monitoring whether the counterweight 3 is rotating is installed at a position adjacent to the connecting rope 202 and the counterweight 3.

[0021] The retractable assembly includes a drive motor 2 and a pay-off drum 201. The drive motor 2 is fixedly connected to the upper end of the bracket 1. A through opening is opened at the upper end of the bracket 1. The pay-off drum 201 is rotatably connected in the through opening. The output end of the drive motor 2 is fixedly connected to the central axis of one side of the pay-off drum 201.

[0022] The monitoring component includes a fixed plate 204, a wave ring 307 and a laser rangefinder 205. The fixed plate 204 is fixedly connected to the connecting rope 202 near the counterweight 3. The wave ring 307 is fixedly connected to the upper end surface of the counterweight 3. The laser rangefinder 205 is fixedly connected to the lower surface of the fixed plate 204. The detection end of the laser rangefinder 205 is provided with a wavy side facing the wave ring 307.

[0023] For the rainwater and sewage drainage pipes installed on the outer wall of the building, after long-term use, when more debris attached to the pipe wall has affected the drainage effect, the staff can move the device to the top floor of the building, and then place the bracket 1 at the water inlet of the drainage pipe so that the counterweight 3 is located directly above the water inlet of the drainage pipe, and then start the drive motor 2 to control the pay-off drum 201 to rotate and pay the connecting rope 202, and then the counterweight 3 will drive the variable speed motor 303, the rotating shaft 304, and the cleaning brush 306 to move downward, and when the roller 302 moves to the outlet of the drainage pipe, the roller 302 is pressed to retract the tensioning telescopic rod 301, so that the roller 302 can be moved into the drainage pipe and connected with the drainage pipe under the tensioning force of the tensioning telescopic rod 301. The inner wall is tightly attached. When the counterweight block 306 is completely entered into the drain pipe, the variable speed motor 303 can be started while the connecting rope 202 is being paid out at a uniform speed. The variable speed motor 303 will drive the rotating shaft 304 to rotate, and the rotating shaft 304 will drive the cleaning brush 306 to rotate through the tension telescopic rod 305. It should be noted that at the beginning, the cleaning brush 306 is first controlled to rotate quickly, and then the cleaning brush 306 will overcome the tension of the tension telescopic rod 305 under the action of centrifugal force and move outward, thereby ensuring that the cleaning surface of the cleaning brush 306 is tightly attached to the wall of the drain pipe, so that the debris attached to the wall of the drain pipe can be cleaned, and the cleaning surface of the cleaning brush 306 can be a wire brush, thereby improving the cleaning effect of the debris on the pipe wall.

[0024] As the cleaning brush 306 moves downward to clean, when the cleaning brush 306 moves to the wall of the drain pipe, the debris attached to the wall is relatively hard and has a large adhesion force that cannot be easily removed, the cleaning brush 306 may be blocked or rotate slowly. At this time, the counterweight block 3 will overcome the lateral friction between the roller 302 and the inner wall of the drain pipe under the reverse action of the cleaning brush 306 and rotate, and then the counterweight block 3 will drive the wave ring 307 to rotate. Since the counterweight block 3 is rotatably connected to the connecting rope 202, the wave ring 307 installed on the connecting rope 202 The fixed plate 204 will not rotate or will only rotate slightly. At this time, the distance value monitored by the laser rangefinder 205 will change. When the staff learns that the value monitored by the laser rangefinder 205 has changed, they can control the variable speed motor 303 to reduce the transmission power, and then the rotation speed of the cleaning brush 306 will decrease. At the same time, the centrifugal force on the cleaning brush 306 will also decrease. Then, the cleaning brush 306 will move back one end under the pulling force of the tension telescopic rod 305, and the drive motor 2 will be turned off at the same time. The cleaning brush 306 stops moving downward, so that the cleaning brush 306 can only clean the inner surface of the harder debris. After cleaning the inner surface of the debris for a period of time, the transmission power of the variable speed motor 303 can be gradually increased, and then the rotation speed of the cleaning brush 306 will gradually increase. At the same time, the cleaning brush 306 will gradually move toward the wall of the drain pipe, so that the debris can be cleaned in a gradually disintegrating manner. When the cleaning brush 306 returns to the initial rotation speed and does not cause the counterweight block 3 to rotate, It can be known that the debris at that position on the drain pipe wall has been cleaned up, and then the connecting rope 202 can be paid out again, wherein the connecting rope 202 can adopt the sum of the length of the drain pipe and the bracket 1, so that when the pay-out drum 201 pays out all the connecting rope 202, the inner wall of the drain pipe can be cleaned once. At the same time, the pay-out drum 201 will automatically reel in the connecting rope 202, and then the cleaning brush 306 will move up. When the cleaning brush 306 moves up and leaves the drain pipe, a back and forth cleaning work of the inner wall of the drain pipe can be completed.

[0025] It should be noted that when the inner wall of the drain pipe is cleaned by rotating the cleaning brush 306, water can be delivered into the drain pipe at the same time, so that the cleaned debris can be quickly flushed out of the drain pipe in combination with the water flow, thereby improving the dredging effect of the drain pipe.

[0026] Embodiment 2:

[0027] Reference Figure 1-Figure 3, a device for desilting the wall of a building drainage pipe is basically the same as that of Example 1, and furthermore: a guide cone 102 is fixedly connected to the lower end of the bracket 1 through a support plate, and the guide cone 102 and the counterweight 3 are on the same central axis, wherein the lower end opening of the guide cone 102 is on the same horizontal plane as the bottom of the bracket 1, and when it is necessary to put the cleaning brush 306, the counterweight 3, the tensioning telescopic rod 301 and the roller 302 and other components into the drainage pipe, the wire-releasing drum 201 can be rotated to protect the connecting rope 202, and then the counterweight 3 It will drive the components connected to it to move downward. When the roller 302 contacts the inclined inner wall of the guiding cone 102, the staff presses down the counterweight 3, and the multiple tensioning telescopic rods 301 can be retracted synchronously with the cooperation of the guiding cone 102, so that the counterweight 3 and other components connected to it can be moved down into the drain pipe to perform pipe wall dredging. Through the setting of the guiding cone 102, the tensioning telescopic rod 301 can be quickly compressed, which effectively improves the work efficiency of placing it into the drain pipe, providing convenience for the staff to operate the device.

[0028] A stabilizing plate 101 is fixedly connected to the bracket 1, and the stabilizing plate 101 is located between the retractable assembly and the counterweight block 3. A through hole is opened on the stabilizing plate 101, which is smaller than the diameter of the counterweight block 3 and larger than the diameter of the fixed plate 204. Through the setting of the stabilizing plate 101, when not in use, the counterweight block 3 can be moved up through the connecting rope 202 until the counterweight block 3 is tightly attached to the lower surface of the stabilizing plate 101, thereby improving the overall stability of the device during transportation.

[0029] The support 1 is rotatably connected to the limiting wheel 203 through the support rod, and the connecting rope 202 passes between the two limiting wheels 203. Figure 1 As shown, by setting two limiting wheels 203, the position of the connecting rope 202 can be limited, so that its counterweight block 3 can be located at the center of the bracket 1, thereby improving the stability of the device during use and transportation.
