Description

A municipal pipeline dredging device Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, specifically a municipal pipeline dredging device. Background Technology

[0002] Municipal pipeline dredging equipment is a specialized mechanical device used to clean silt, debris, oil, and other sediments from urban drainage pipes (such as rainwater pipes and sewage pipes). Its core function is to remove blockages from pipes through physical, hydraulic, or mechanical means, restoring pipe flow capacity, preventing urban flooding and water pollution, and ensuring the normal operation of the municipal pipeline system. It has a wide range of applications, including urban drainage networks, industrial pipelines, pre-treatment before upgrading old pipelines, and underground utility tunnels.

[0003] The working process of municipal pipeline dredging equipment usually follows a standardized process of "survey and assessment - site preparation - dredging operation - effect acceptance - finishing treatment". The specific steps may vary depending on the type of pipeline, degree of blockage and equipment type.

[0004] During the operation of municipal pipeline dredging devices, sludge and debris often clog the suction port or even the suction pump. Once clogged, work must be stopped, and manual dredging and pipe replacement must be carried out, significantly reducing the efficiency of the dredging work. Currently available municipal pipeline dredging devices generally lack the ability to efficiently solve this problem. Therefore, this invention provides a municipal pipeline dredging device with a self-cleaning filter that does not affect the suction operation during maintenance and replacement to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this utility model embodiment is to provide a municipal pipeline dredging device, which aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A municipal pipeline dredging device includes a main suction pipe, one end of which is connected to two branch suction pipes. A flow meter and a solenoid valve are installed on the surface of each branch suction pipe. An elastic interface is installed at the end of each branch suction pipe away from the main suction pipe, and a filter screen is elastically installed inside the elastic interface.

[0008] The surface of the main water intake pipe is equipped with a mounting bracket, and the surface of the mounting bracket is equipped with a rotating disk mounting seat and a fixed frame. The surface of the rotating disk mounting seat is equipped with a rotating disk, and the surface of the rotating disk is equipped with a drive motor. A rotating shaft is fixedly installed at the center point of the surface of the rotating disk, and one end of the rotating shaft is connected to the output end of the drive motor. The surface of the rotating disk is equipped with a protrusion, and a track is sleeved on the outside of the protrusion. Push rods are connected to both sides of the track, and the push rods are slidably connected to the fixed frame.

[0009] Furthermore, an elastic element is provided between the elastic interface and the filter screen, and they are elastically assembled together by the elastic element, which is a spring.

[0010] Furthermore, the end of the push rod away from the track is opposite to the surface of the filter screen.

[0011] Furthermore, the filter screen is a wedge-shaped filter.

[0012] Furthermore, a PLC intelligent controller is installed on the surface of the main water intake pipe, and the PLC intelligent controller is electrically connected to the flow meter, solenoid valve and drive motor.

[0013] Furthermore, the surface of the main suction pipe is provided with clamps, and the mounting bracket is installed together with the main suction pipe through the clamps.

[0014] The municipal pipeline dredging device provided by this utility model has the following beneficial effects:

[0015] By incorporating a flow meter, solenoid valve, filter screen, rotating disc, and push rod, the municipal pipeline dredging device operates by first engaging one suction branch pipe. When the flow meter detects a decrease in flow, indicating blockage in the filter screen, the solenoid valve on the working pipe is closed, while the solenoid valve on the other parallel suction branch pipe is opened to perform its replacement function. Simultaneously, the drive motor is activated, causing the rotating disc to rotate and the push rod to continuously strike the surface of the filter screen, achieving automatic unblocking and cleaning. Therefore, this utility model provides a municipal pipeline dredging device with a self-cleaning filter screen that does not affect the suction operation during maintenance and replacement.

[0020] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] As shown in Figure 1, this embodiment of the utility model provides a municipal pipeline dredging device, including a main suction pipe 1. In actual engineering projects, the material of the main suction pipe 1 can typically be ductile iron pipe, rigid polyvinyl chloride pipe, etc. The above-mentioned technical features are all mature existing technologies, and are technical solutions that are readily available or conceived by those skilled in the art. Those skilled in the art can make corresponding adjustments and selections based on the above technical solutions.

[0023] As shown in Figures 1 and 2, in one embodiment of this utility model, one end of the main suction pipe 1 is connected to two suction branch pipes 2. A flow meter 3 and a solenoid valve 4 are installed on the surface of each suction branch pipe 2. The flow meter 3 is used to monitor the water flow rate inside the suction branch pipe 2. When the flow rate of the flow meter 3 is lower than a preset value, it indicates that there is a blockage upstream of the suction branch pipe 2. The solenoid valve 4 can automatically open and close the flow of the suction branch pipe 2. A flexible interface 5 is installed at the end of the suction branch pipe 2 away from the main suction pipe 1, and a filter screen 6 is elastically installed inside the flexible interface 5.

[0024] A mounting bracket 8 is installed on the surface of the main suction pipe 1, and a rotating disk mounting base 9 and a fixed bracket 15 are mounted on the surface of the mounting bracket 8. A rotating disk 10 is mounted on the surface of the rotating disk mounting base 9, and a drive motor is mounted on the surface of the rotating disk 10. A rotating shaft 11 is fixedly mounted at the center point of the surface of the rotating disk 10, and one end of the rotating shaft 11 is connected to the output end of the drive motor. A protrusion 12 is mounted on the surface of the rotating disk 10, and a track 13 is sleeved on the outside of the protrusion 12. Push rods 14 are connected to both sides of the track 13, and the push rods 14 are slidably connected to the fixed bracket 15.

[0025] In this embodiment, the end of the push rod 14 away from the track 13 is opposite to the surface of the filter screen 6. This design is intended to enable the push rod 14 to effectively and intermittently impact the surface of the filter screen 6, causing the debris and sludge clogging the surface to be affected by the vibration until they fall off.

[0026] In this embodiment, the filter screen 6 uses a wedge-shaped filter. This design takes into account that the trapezoidal slits on the surface of the wedge-shaped filter have a "wider at the top and narrower at the bottom" structure, which maximizes the filtration area. For the same pore size, the flow rate is 30%-50% higher than that of traditional round-hole mesh or woven mesh. Similarly, the wedge-shaped filter is less prone to clogging, which reduces its clogging efficiency.

[0027] In this embodiment, a PLC intelligent controller is installed on the surface of the main suction pipe 1, and the PLC intelligent controller is electrically connected to the flow meter 3, the solenoid valve 4, and the drive motor. This design takes into account that the PLC intelligent controller can automate the monitoring of flow rate and the opening and closing of the pipeline. When the flow meter 3 on the surface of the working suction branch pipe 2 detects that the flow velocity in the pipeline is lower than a certain value, the PLC intelligent controller closes the solenoid valve 4 on the surface of the working suction branch pipe 2 and simultaneously opens the solenoid valve 4 on the surface of another suction branch pipe 2. This allows the pipeline to continue operating even when blockage occurs.

[0028] In this embodiment, a clamp 7 is provided on the surface of the main suction pipe 1, and the mounting bracket 8 is mounted together with the main suction pipe 1 via the clamp 7. This design takes into account that the mounting bracket 8 is easily affected during the swinging of the push rod 14. Therefore, using the clamp 7 as a fixing element to fix it to the surface of the main suction pipe 1 can ensure that the push rod 14 still has stability during operation.

[0029] As shown in Figure 3, in one embodiment of this utility model, an elastic element is provided between the elastic interface 5 and the filter screen 6, and they are elastically assembled together by the elastic element, which is a spring 16. This design takes into account that the intermittent impact of the push rod 14 on the filter screen 6 requires a certain amount of movement space, and the spring 16, as a stable elastic element, is a good choice. Using the spring 16 inside the elastic interface 5 as an elastic medium, the filter screen 6 is fixed inside the elastic interface 5 through elastic installation, thereby achieving a stable yet elastically movable effect.

[0030] The working principle of this utility model is as follows: During the operation of the municipal pipeline dredging device, sludge and debris often clog the suction port or even the suction pump. At this time, the operator uses the flow meter 3 to monitor the flow and the solenoid valve 4 to control the opening and closing of the suction branch pipe 2, switching the operating pipeline. Simultaneously, the drive motor is started, causing the rotating disk 10 and its surface protrusions 12 to rotate. Since the protrusions 12 are fitted with a track 13, and the push rods 14 on both sides of the track 13 face the surface of the filter screen 6, the debris and sludge clogging the surface of the filter screen 6 can be gradually dislodged by the continuous impact of the push rods 14. Therefore, the municipal pipeline dredging device provided by this utility model achieves the effect of having a self-cleaning filter screen without affecting the suction operation during maintenance and replacement.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
