Description

Technical Field

[0001] This utility model relates to the field of dredging equipment technology, and in particular to a dredging equipment for water supply and drainage channels. Background Technology

[0002] In highway engineering and municipal water supply and drainage systems, water channels serve as crucial infrastructure, undertaking key functions such as drainage, flood control, and irrigation. Their smooth operation directly affects the safe operation of projects and the normal functioning of cities. Over time, water channels easily accumulate large amounts of silt and debris. If not cleaned in a timely manner, this can lead to a decrease in drainage capacity and even cause blockages and waterlogging, affecting the surrounding environment and residents' lives. Therefore, regular dredging of water channels is a necessary step to ensure their functionality.

[0003] Currently, there are many types of dredging equipment for water supply and drainage channels on the market, but there are still significant shortcomings in practical applications. When dredging the sidewalls of channels with different inclination angles, the side scraper angle of traditional equipment is mostly fixed or has a limited adjustment range, making it difficult to accurately adapt to diverse channel types. When facing sidewalls with large differences in inclination angle, the side scraper cannot fit tightly, which not only leads to incomplete removal of sludge from the sidewalls, creating sanitary dead corners, but also may cause secondary pollution of the cleaned areas due to leaked sludge due to inadequate sealing, increasing the workload of secondary cleaning and seriously affecting dredging efficiency. At the same time, existing equipment is not perfect in treating the dredged sludge. Most of them directly collect and transport sludge containing a large amount of water, which is not only costly to transport, but also prone to water leakage during transportation, causing secondary pollution, and failing to meet the requirements of energy conservation, environmental protection and efficient treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dredging device for water supply and drainage channels. Through the coordinated design of an electric telescopic rod and a fan-shaped baffle, the inclination angle of the side scraper can be flexibly adjusted to adapt to different channel sidewalls, preventing sludge leakage and improving dredging efficiency. Simultaneously, the columnar filter screen and extrusion plate design effectively filter water and compress sludge, facilitating subsequent processing and contributing to energy conservation and environmental protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dredging device for water supply and drainage channels, comprising a base plate, a sludge suction box fixedly connected to the upper left side of the base plate, a connecting rod connected to the left side of the sludge suction box via a rotating assembly, a connecting piece rotatably connected to one end of the connecting rod, a support plate fixedly connected to the top of the sludge suction box, an electric telescopic rod fixedly connected to the left end of the support plate, a drive end of the electric telescopic rod fixedly connected to the upper end of the connecting piece, a sludge suction pump fixedly connected to the inner wall of the sludge suction box, a connecting pipe fixedly connected to the right end of the sludge suction pump, a treatment box fixedly connected to the right end of the connecting pipe, a sewage delivery pipe fixedly connected to the right end of the treatment box, a columnar filter screen sleeved on the inner wall of the sewage delivery pipe, a spiral conveyor sleeved on the inner wall of the columnar filter screen, an extrusion plate connected to the right end of the sewage delivery pipe via an extrusion assembly, and a sludge collection box fixedly connected to the upper right side of the base plate.

[0006] Furthermore, the rotating assembly includes a bottom scraper fixedly connected to the lower left side of the suction box, side scrapers rotatably connected to the front and rear sides of the bottom scraper, a fan-shaped baffle fixedly connected to the right end of the side scraper, and a connecting rod rotatably connected to the top of the side scraper.

[0007] Furthermore, the extrusion assembly includes a fixing ring fixedly connected to the right end of the sewage pipe, a fixing rod fixedly connected to the outer wall of the right end of the sewage pipe, a fixing plate fixedly connected to the right end of the fixing rod, a spring connected to the left end of the fixing plate, and the extrusion plate connected to the left end of the spring.

[0008] Furthermore, one side of the fan-shaped baffle is fixedly connected to the side of the suction box, and the fan-shaped baffle is made of several arc-shaped plates hinged together in sequence, with a sliding rail for limiting the movement between adjacent plates.

[0009] Furthermore, a motor is fixedly connected to the right end of the fixed plate, and the motor drive end is fixedly connected to the right end of the screw conveyor.

[0010] Furthermore, a suction port is provided at the left end of the suction box, and a drain pipe is fixedly connected to the lower left end of the sewage delivery pipe.

[0011] Furthermore, the right end of the sewage pipe extends into the sludge collection box, and the left end of the screw conveyor and the left end of the columnar filter extend into the processing box.

[0012] Furthermore, the lower end of the base plate is provided with casters, and the right end of the base plate is provided with a push rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the linkage structure of the electric telescopic rod, connecting parts, and connecting rod allows for flexible adjustment of the side scraper's inclination angle, precisely adapting to the sidewalls of water channels with different inclination angles, breaking the dependence of traditional dredging equipment on a single channel type. Simultaneously, the fan-shaped baffle adopts a folding fan design, opening and closing synchronously with the side scraper's inclination angle, tightly fitting the sidewall to form an effective barrier, preventing silt leakage into the cleaned area, and ensuring that silt on the channel bottom and sidewalls is thoroughly removed. This design reduces secondary cleaning work caused by differences in channel type and avoids unsanitary dead zones caused by missed cleaning, significantly improving the comprehensiveness and efficiency of dredging operations.

[0015] 2. In this utility model, the columnar filter screen and extrusion plate design can effectively filter excess water in the sludge and compress the volume of the sludge, which significantly reduces the water content of the cleaned sludge, making it easier for subsequent processing and transportation. At the same time, it reduces the possibility of water backflow and secondary pollution during the sludge removal process, and has the dual advantages of energy saving, environmental protection and high efficiency.

[0023] 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.

[0024] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a dredging device for water supply and drainage channels, comprising a base plate 1, a caster wheel at the lower end of the base plate 1, a push rod at the right end of the base plate 1, a suction box 2 fixedly connected to the upper left side of the base plate 1, a suction port 10 at the left end of the suction box 2, a bottom scraper 3 fixedly connected to the lower left side of the suction box 2, side scrapers 4 rotatably connected to the front and rear sides of the bottom scraper 3, a fan-shaped baffle 5 fixedly connected to the right end of the side scraper 4, one side of the fan-shaped baffle 5 fixedly connected to the side of the suction box 2, the fan-shaped baffle 5 being made of several arc-shaped plates hinged in sequence, with sliding rails limiting the adjacent plates, a connecting rod 6 rotatably connected to the top of the side scraper 4, a connecting piece 7 rotatably connected to one end of the connecting rod 6, a support plate 9 fixedly connected to the top of the suction box 2, an electric telescopic rod 8 fixedly connected to the left end of the support plate 9, the drive end of the electric telescopic rod 8 fixedly connected to the upper end of the connecting piece 7, and a suction pump 11 fixedly connected to the inner wall of the suction box 2.

[0025] Specifically, when using this dredging device, it must first be placed at the bottom of the ditch to be cleaned. The operator can then drive the device forward along the ditch bottom by pushing the push rod. During this process, the bottom scraper 3 on the device cleans the silt at the bottom of the ditch, while the side scraper 4 removes silt from the side walls of the ditch. The suction pump 11 sucks the cleaned silt into the device through the suction port 10. To adapt to different angles of the ditch side walls, the extension and retraction of the electric telescopic rod 8 can be controlled: when the electric telescopic rod 8 extends or retracts, it drives the connecting piece 7 to move up and down, which in turn moves the connecting rod 6, ultimately causing the side scraper 4 to rotate around its bottom end, thus changing the angle of the side scraper 4. The fan-shaped baffle 5, which works in conjunction with the side scraper 4, is designed to mimic the principle of a folding fan, consisting of several arc-shaped plates hinged together, with sliding rails between adjacent plates for limiting movement. When the side scraper 4 adjusts its angle, the fan-shaped baffle will slide open and close accordingly, effectively blocking silt and preventing it from leaking into the already cleaned area.

[0026] Reference Figures 3-5A connecting pipe 12 is fixedly connected to the right end of the sludge suction pump 11. A treatment tank 13 is fixedly connected to the right end of the connecting pipe 12. A sewage delivery pipe 14 is fixedly connected to the right end of the treatment tank 13. A drain pipe 17 is fixedly connected to the lower left end of the sewage delivery pipe 14. A columnar filter screen 15 is fitted inside the sewage delivery pipe 14. A screw conveyor 16 is fitted inside the columnar filter screen 15. The left ends of the screw conveyor 16 and the left ends of the columnar filter screen 15 extend into the treatment tank 13 and are fixedly connected to the right end of the sewage delivery pipe 14. The fixed ring 18 at the end, the outer wall of the right end of the sewage pipe 14 is fixedly connected to the fixed rod 23, the right end of the fixed rod 23 is fixedly connected to the fixed plate 21, the right end of the fixed plate 21 is fixedly connected to the motor 22, the drive end of the motor 22 is fixedly connected to the right end of the screw conveyor 16, the left end of the fixed plate 21 is connected to the spring 20, the extrusion plate 19 is connected to the left end of the spring 20, the upper right side of the bottom plate 1 is fixedly connected to the sludge collection box 24, and the right end of the sewage pipe 14 extends into the sludge collection box 24.

[0027] Specifically, the sludge sucked in by the suction pump 11 is discharged into the treatment tank 13 via the connecting pipe 12, and then conveyed to the collection tank 24 by the screw conveyor 16. The treatment tank 13 is equipped with a guide plate to facilitate the sludge entering the feed inlet of the screw conveyor 16. During the conveying process, the columnar filter screen 15 filters out excess water in the sludge, and the filtered water is discharged through the drain pipe 17. When the sludge is conveyed to the rightmost end, since the spring 20 is initially in a compressed state, the squeezing plate 19 is initially in close contact with the fixing ring 18, and the sludge will be squeezed out of excess water at the rightmost end. This water is also filtered by the columnar filter screen 15 and discharged through the drain pipe 17. As the sludge continues to accumulate, it will push the squeezing plate 19 to the right and compress the spring 20. Due to the obstruction of the squeezing plate 19, the sludge will not come into contact with the spring 20. When a gap is created between the squeezing plate 19 and the retaining ring 18, the sludge, having had its water squeezed out, falls into the sludge collection box 24 through the gap. The elastic coefficient of the spring 20 is in the range of 50-100 N / m, meeting the squeezing requirements for the sludge. This design reduces the moisture content in the cleaned sludge, facilitating subsequent processing. Once the sludge collection box 24 is full, simply move the device to the sludge treatment area and unload the sludge.

[0028] Working principle: When using this device, place it at the bottom of the ditch that needs to be dredged. The operator moves the device forward by pushing the push rod. The bottom scraper 3 and the side scraper 4 clean the silt on the bottom and side walls of the ditch, respectively. The silt pump 11 sucks the silt into the device through the suction port 10. By controlling the extension and retraction of the electric telescopic rod 8, the connecting piece 7 moves up and down. The connecting rod 6 moves accordingly, causing the side scraper 4 to rotate around its bottom end, thereby changing the tilt angle of the side scraper 4 to adapt to different tilt angles of the ditch side walls. The fan-shaped baffle 5 imitates the principle of a folding fan and is made of several arc-shaped plates hinged in sequence. The adjacent plates are limited by sliding rails. When the side scraper 4 changes its tilt angle, the fan-shaped baffle slides to open and close. The sludge is sucked into the suction pump 11, discharged into the treatment tank 13 via the connecting pipe 12, and then conveyed to the collection tank 24 via the screw conveyor 16. During the conveying process, the columnar filter screen 15 filters out excess water, which is then discharged through the drain pipe 17. When the sludge reaches the rightmost end, because the squeezing plate 19 is initially tightly fitted with the fixing ring 18, the sludge is squeezed out of excess water at the rightmost end and filtered by the columnar filter screen 15 before being discharged through the drain pipe 17. The accumulated sludge squeezes the squeezing plate 19, pushing it to the right and compressing the spring 20. When a gap is squeezed between the squeezing plate 19 and the fixing ring 18, the sludge with squeezed water falls into the collection tank 24 through the gap. Once the collection tank 24 is full, the device is moved to the sludge treatment area, and the sludge is unloaded.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
