Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering maintenance equipment, specifically to automatic dredging equipment for water conservancy ditches. Background Technology

[0002] Irrigation ditches are man-made waterway systems used for irrigation, drainage, flood control, and water supply. They can transport water to farmland, cities, and other areas, or promptly remove excess water, ensuring the stability of production, daily life, and the ecological environment. Irrigation ditch dredging involves removing long-term accumulated sediments such as silt, weeds, and garbage from ditches using manual or mechanical methods. This restores the ditches' water conveyance and flood control capabilities, improves water quality, and ensures the continued normal function and benefits of the irrigation ditches.

[0003] A search revealed Chinese Patent Publication No. CN219638000U, which discloses a water conservancy ditch cleaning device. The device includes a support frame, one end of which is fixedly connected to a handle, and the inner wall of the support frame is fixedly connected to an opposite side via a reinforcing arm. By using this structure, it can be adjusted to accommodate different ditches, avoiding the need for multiple cleaning operations for excessively large ditches.

[0004] Existing technologies often have the following problems when used:

[0005] Currently used water conservancy ditch dredging and adjustment structures still largely rely on manual adjustment. When faced with ditches of different depths and widths, dredging equipment cannot automatically adjust the dredging depth and range according to the depth and width of the ditch. This not only requires frequent manual adjustment of the equipment's dredging range, affecting the efficiency of dredging operations, but also makes it difficult for the equipment to accurately cover the dredging area during the dredging operation, easily resulting in missed areas or incomplete dredging, thus affecting the dredging effect of water conservancy ditches. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this utility model provides an automatic dredging device for water conservancy ditches. This device effectively solves the problems of existing water conservancy ditches dredging equipment relying heavily on manual adjustment, being unable to adaptively adjust the dredging structure when faced with ditches of different depths and widths, resulting in low efficiency and incomplete dredging.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an automatic dredging device for water conservancy ditches, comprising:

[0009] A movable frame, wherein two self-driving wheels and a movable wheel are fixedly installed at the bottom end of the movable frame;

[0010] An adaptive dredging component includes two sliding frames fixedly connected to the lower end face of a movable frame. A lifting plate is slidably connected to the inner side of each sliding frame. A central dredging base plate is fixedly connected to the lower end face of each lifting plate. A lifting drive component is fixedly connected between the two sliding frames. The lifting drive component drives the central dredging base plate to move up and down. A groove is formed on the lower end face of the central dredging base plate. A width adjustment component is slidably connected to the inner side of the groove. The width adjustment component adaptively adjusts the dredging width.

[0011] Furthermore, the lifting drive component includes two support frames fixedly connected between two sliding frames, a ball screw rotatably connected at the center of the two support frames, a guide block threaded onto the ball screw, the guide block being fixedly connected to the upper end of the two lifting plates through two connecting frames, a servo motor being fixedly installed on the top surface inside the moving frame, and the output end of the servo motor being fixedly connected to the upper end of the ball screw.

[0012] Furthermore, the wide-distance adjustment component includes two lateral dredging base plates slidably connected to the inner side of the chute, and two small electric push rods are fixedly installed on the outer wall of the central dredging base plate. The telescopic ends of the two small electric push rods are respectively fixedly connected to the outer walls of the two lateral dredging base plates.

[0013] Furthermore, the adaptive dredging component also includes a PLC controller fixedly installed on the upper surface of the mobile frame. A vision sensor is fixedly installed on the top surface inside the mobile frame. The vision sensor is used to monitor the depth and width of the irrigation ditch in real time. The PLC controller, two self-driving wheels, the vision sensor, the servo motor, and two small electric push rods are electrically connected to an external power supply.

[0014] Furthermore, filter screens are fixedly connected to the top of the central dredging base plate and the two side dredging base plates.

[0015] Furthermore, both of the sliding frame sidewalls are provided with sliding holes, and the connecting frame slides with the sliding frame through the sliding holes.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention incorporates an adaptive dredging component. A visual sensor monitors the depth and width of the irrigation ditch and transmits this data to a PLC controller. The PLC controller then controls a servo motor to move the lifting plate and the central dredging base plate, automatically adjusting the central dredging base plate to the appropriate dredging depth. Simultaneously, the PLC controller uses the ditch width data from the visual sensor to control two small electric actuators. The extension and retraction ends of these actuators move the lateral dredging base plates relative to the central dredging base plate, automatically adjusting the overall dredging width of the central and lateral base plates. This allows for adaptive adjustment of the dredging depth and range based on the ditch's depth and width, effectively improving dredging efficiency and precision, thus ensuring the optimal dredging effect.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 3 An automatic dredging device for water conservancy ditches includes: a mobile frame 1 and an adaptive dredging component. The mobile frame 1 has two self-driving wheels 2 and a mobile wheel 3 fixedly installed at its bottom. The adaptive dredging component includes two sliding frames 4 fixedly connected to the lower end face of the mobile frame 1. Lifting plates 5 are slidably connected to the inner sides of each sliding frame 4. A central dredging base plate 6 is fixedly connected to the lower end face of each lifting plate 5. A lifting drive component is fixedly connected between the two sliding frames 4. The lifting drive component drives the central dredging base plate 6 to move up and down. The lifting drive component includes a fixed... Two support frames 8 are connected between two sliding frames 4. A ball screw is rotatably connected at the center of the two support frames 8. A guide block 10 is threaded on the ball screw 9. The guide block 10 is fixedly connected to the upper end of the two lifting plates 5 through two connecting frames. Sliding holes 16 are opened on the side walls of the two sliding frames 4. The connecting frame slides with the sliding frame 4 through the sliding holes 16. A servo motor 11 is fixedly installed on the top surface inside the moving frame 1. The servo motor 11 is model 80DK-M07725. The output end of the servo motor 11 is fixedly connected to the upper end of the ball screw 9.

[0026] A groove 7 is provided on the lower end face of the central dredging base plate 6. A width adjustment component is slidably connected to the inner side of the groove 7. The width adjustment component is used to adaptively adjust the dredging width. The width adjustment component includes two lateral dredging base plates 12 slidably connected to the inner side of the groove 7. A filter screen plate 15 is fixedly connected to the top of the central dredging base plate 6 and the two lateral dredging base plates 12. Two small electric push rods 13 are fixedly installed on the outer wall of the central dredging base plate 6. The small electric push rods 13 are model DATIEE-IMD3. The telescopic ends of the two small electric push rods 13 are fixedly connected to the outer walls of the two lateral dredging base plates 12 respectively. The adaptive dredging component also includes a PLC controller 17 fixedly installed on the upper end face of the moving frame 1. A vision sensor 14 is fixedly installed on the inner top surface of the moving frame 1. The vision sensor 14 is used to monitor the depth and width of the water conservancy ditch in real time. The PLC controller 17, two self-driven bottom wheels 2, vision sensor 14, servo motor 11, and two small electric push rods 13 are electrically connected to an external power supply.

[0027] Specifically, both self-driven bottom wheels 2 are equipped with stepper motors as drive sources. The stepper motors use signal 42BYG250C-0401A. The two self-driven bottom wheels 2 are evenly distributed on both sides of the bottom of the mobile frame 1. The PLC controller 17 has a built-in time relay soft element, which can control the two self-driven bottom wheels 2 to run synchronously, so as to ensure the stability of the mobile frame 1 in dredging.

[0028] Specifically, when the drive guide block 10 is raised and lowered, the connecting frame can slide and engage with the slide frame 4 through the sliding hole to limit the raising and lowering movement of the guide block 10 and ensure the stability of the depth adjustment of the central dredging bottom plate 6.

[0029] The depth and width data of the irrigation ditch can be monitored by the vision sensor 14 and transmitted to the PLC controller 17. The PLC controller 17 controls the servo motor 11 to start according to the preset program and the real-time data of the vision sensor 14, so that the servo motor 11 can drive the ball screw 9 to rotate and the guide block 10 to move up and down, so as to drive the lifting plate 5 and the central dredging base plate 6 to move up and down through the guide block 10, thereby automatically adjusting the central dredging base plate 6 to the appropriate dredging depth.

[0030] Specifically, the lower end face of the central dredging base plate 6 is at the same level as the lower end faces of the two lateral dredging base plates 12. The central dredging base plate 6 and the two lateral dredging base plates 12 can be used to scrape and collect the silt and debris in the ditch. The silt and debris are collected above the central dredging base plate 6 and the two lateral dredging base plates 12 after being preliminarily filtered by the filter screen plate 15.

[0031] Specifically, during the dredging process, the vision sensor 14 continuously monitors the condition of the irrigation ditch, and the PLC controller 17 adjusts the overall depth and width of the central dredging base plate 6 and the two lateral dredging base plates 12 in real time according to the actual situation of the irrigation ditch, so as to ensure the efficiency and accuracy of the dredging work.

[0032] Meanwhile, the PLC controller 17 controls the operation of the two small electric push rods 13 based on the ditch width data from the vision sensor 14. This allows the extension and retraction ends of the two small electric push rods 13 to move the lateral dredging base plate around the central dredging base plate 6, thereby automatically adjusting the overall dredging width of the central dredging base plate 6 and the two lateral dredging base plates 12. This enables adaptive adjustment of the dredging depth and range according to the depth and width of the irrigation ditch, effectively improving the efficiency of dredging operations and enhancing the accuracy of the dredging area, thus ensuring the dredging effect of the irrigation ditch.

[0033] The working principle of this utility model is as follows:

[0034] When the equipment is working, the self-driven bottom wheel 2 drives the moving frame 1 to the location of the water conservancy ditch to be dredged. The vision sensor 14 monitors the depth and width data of the water conservancy ditch and transmits the data to the PLC controller 17. The PLC controller 17 controls the servo motor 11 to start according to the preset program and the real-time data of the vision sensor 14, so that the servo motor 11 drives the ball screw 9 to rotate, so that the guide block 10 can move up and down along the axis of the ball screw 9. Then, through the connecting frame, the lifting plate 5 and the central dredging base plate 6 are lifted and moved up and down to automatically adjust the central dredging base plate 6 to the appropriate dredging depth. At the same time, the PLC controller 17 controls the operation of the two small electric push rods 13 according to the ditch width data of the vision sensor 14, so that the extension end of the two small electric push rods 13 can drive the lateral dredging base plates to move on the central dredging base plate 6 to automatically adjust the overall dredging width of the central dredging base plate 6 and the two lateral dredging base plates 12.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
