Description

Technical Field

[0001] This utility model relates to the field of sludge cleaning technology, specifically to a convenient intelligent sludge cleaning device. Background Technology

[0002] In municipal drainage systems, river management, and construction sites, silt removal is a crucial step in ensuring the normal operation of infrastructure. Traditional manual silt removal requires workers to enter silt pools with handheld high-pressure water guns, using mechanical agitation and mud pumps to complete the cleanup. This method is not only labor-intensive and inefficient but also poses safety hazards such as slips and falls and poisoning. With the development of intelligent technologies, silt removal equipment is gradually replacing manual labor. For example, high-pressure water gun silt removal trucks and vacuum trucks improve efficiency through mechanized operations. However, existing equipment still has significant shortcomings under complex working conditions.

[0003] Currently available high-pressure water jet dredging vehicles, such as Yugong Machinery's intelligent dredging robot, while capable of flushing silt with high-pressure water jets, generally use water jet nozzles with fixed orifice diameters. This prevents them from dynamically adjusting water output parameters based on the actual conditions of the work module. When encountering large debris such as stones or branches, the fixed orifice diameter water jets, due to insufficient water flow velocity, fail to effectively disperse or move the debris, leading to debris accumulation and clogging of the suction port, requiring frequent shutdowns for manual cleaning. For example, when traditional high-pressure water jet dredging vehicles handle viscous silt or mixed hard impurities, the fixed water jet outlet velocity prevents the increase of kinetic energy by reducing the orifice diameter, causing large debris to remain in the work area and severely impacting dredging efficiency. Therefore, a convenient intelligent silt cleaning device is proposed. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a convenient intelligent sludge cleaning device. By utilizing the squeezing force caused by hardened sludge or large impurities during the sludge removal process, the device reduces the outlet diameter and increases the water flow velocity, forming a directional high-pressure jet that flushes the impurities to both sides. The device achieves adaptive adjustment of the water flow velocity without manual intervention, significantly improving sludge cleaning efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A convenient intelligent sludge cleaning device includes a sludge cleaning vehicle, a controller inside the sludge cleaning vehicle, a working component for flushing sludge at the front end of the sludge cleaning vehicle, and a suction component for adsorbing and filtering sludge connected to the bottom of the sludge cleaning vehicle. The working component is connected to the suction component. The working component includes a transverse shovel groove, and a high-pressure water gun is connected to the side of the transverse shovel groove near the sludge cleaning vehicle. Fixed perforated plates and symmetrically arranged movable perforated plates are respectively provided in the transverse shovel groove. The fixed perforated plates and movable perforated plates are respectively provided with a plurality of first holes and second holes, and the diameter of the first holes is larger than the diameter of the second holes. The fixed perforated plates are fixedly connected to the transverse shovel groove, and each movable perforated plate is hinged with a shovel plate. The top and bottom ends of the shovel plates are hinged with sliding components, and the top and bottom ends of the movable perforated plates are fixedly connected to the sliding components. The sliding components are used to drive the movable perforated plates to slide in the transverse shovel groove according to the resistance when the shovel plates clean the sludge, so that the second holes and first holes between the movable perforated plates and the fixed perforated plates are misaligned, thereby creating a flow rate difference in the water output of the high-pressure water gun.

[0006] The technical principles of the above solution are as follows:

[0007] During dredging operations, high-pressure water jets deliver water into the transverse shovel groove. The water flows through the first hole of the fixed orifice plate and the second hole of the movable orifice plate before being sprayed out. When the shovel plate cleans sludge, if it encounters large pieces of sludge or impurities, the resistance of the sludge or impurities on the shovel plate is transmitted through the shovel plate to the sliding assembly. The slider in the sliding assembly slides within the groove, simultaneously compressing the spring on the telescopic rod, causing the movable orifice plate to move within the transverse shovel groove, misaligning the second hole and the first hole between the movable and fixed orifice plates. Since the diameter of the second hole is smaller than that of the first hole, the effective cross-sectional area through which the water can flow decreases after the misalignment. According to the principles of fluid mechanics, with a constant flow rate, a smaller cross-sectional area results in an increased flow velocity. This creates a velocity difference in the high-pressure water jet output, and the high-speed water flow can disperse large impurities, preventing blockage of the suction port. At the same time, the shovel plate can rotate around the hinge of the movable orifice plate, working in conjunction with the water flow to impact and break up the plated sludge.

[0008] The above approach has the following beneficial effects:

[0009] 1. This solution utilizes a sliding component and orifice plate misalignment mechanism. When the shovel plate contacts large pieces of silt or impurities, the effective cross-sectional area of ​​the water flow automatically decreases, and the flow velocity increases with the increase of resistance. This allows for adaptive adjustment of the water flow velocity without manual intervention, effectively dispersing large impurities and significantly improving silt removal efficiency.

[0010] 2. In this solution, the shovel can rotate around the hinge, and in conjunction with the impact of high-speed water flow, it can achieve dual crushing of compacted sludge through mechanical shoveling and hydraulic impact, thereby improving the adaptability to complex sludge environments and further enhancing the cleaning effect.

[0011] 3. This solution, based on the mechanical resistance-triggered sliding component, has a compact structure and can achieve adaptive adjustment without a complex electronic control system. It has the advantages of high reliability and low maintenance cost, making it suitable for field or harsh environment operations.

[0012] Furthermore, each sliding component includes a sliding groove and a slider. The sliding groove is opened on the top and bottom walls of the transverse shovel groove, respectively. The slider slides in conjunction with the sliding groove, and each slider is hinged with a connecting rod. Each slider is fixedly connected to the movable perforated plate, and each slider is fixedly connected with a telescopic rod. Each telescopic rod is coaxially sleeved with a spring, and both ends of the spring are fixedly connected to the slider and the side wall of the sliding groove, respectively.

[0013] Beneficial effects: Through the elastic connection between the spring and the telescopic rod, the resistance experienced by the shovel plate is precisely converted into the displacement of the slider, allowing the movable orifice plate and the fixed orifice plate to quickly misalign. The water flow speed is automatically adjusted according to the change in resistance, requiring no manual intervention and improving dredging efficiency. The elastic deformation of the spring can buffer the impact of large impurities on the shovel plate, avoiding rigid collisions that could damage the equipment and extending its service life. When large impurities are washed away or broken, the spring's rebound force resets the slider, and the movable orifice plate returns to its initial position, ensuring continuous and stable operation of the device.

[0014] Furthermore, the angle of movement between the shovel plate and the movable orifice plate is 90° to 120°.

[0015] Beneficial effects: When the angle of movement is 90°, the shovel is perpendicular to the ground, which is suitable for cutting into hardened or solidified sludge layers. It uses mechanical force to break up stubborn deposits and improves cleaning efficiency. The upper limit of the angle range is 120°, which makes the shovel slightly converge towards the middle of the horizontal shovel groove, making it easier to guide the sludge to the suction port and reduce the loss of sludge splashing to both sides.

[0016] Furthermore, each of the second holes has a guide slope on its outer periphery, and the guide slope forms an angle of 30° to 60° with the central axis of the second hole.

[0017] Beneficial effects: The inclined surface guides the high-speed water flow to spray at an angle to both sides, forming a fan-shaped flushing area, expanding the water flow coverage, effectively pushing large pieces of debris to both sides of the sludge truck, and reducing the risk of frontal accumulation and blockage.

[0018] Furthermore, each shovel plate is equipped with a pressure sensor that is connected to the controller signal.

[0019] Beneficial effects: By collecting real-time force data on the shovel plate through pressure sensors, the controller can accurately determine the hardness of the sludge, the size and distribution of impurities, and automatically adjust the power of the high-pressure water gun or the suction force of the suction component.

[0020] Furthermore, the sludge suction assembly includes a sludge suction port connected to the bottom of the sludge dredging vehicle. The inner wall of the sludge suction port is provided with a transverse conveying trough, and the bottom of the conveying trough is provided with several screen holes. Both ends of the conveying trough extend obliquely to the outside of the sludge suction port and are connected to both sides of the sludge dredging vehicle.

[0021] Beneficial effects: The screen holes at the bottom of the conveying trough can intercept large impurities with a diameter larger than the screen holes, such as stones and branches, allowing only small silt and liquids to pass through, preventing large impurities from entering the sludge truck and clogging the suction pipe or conveying trough, thus reducing the risk of equipment failure.

[0022] Furthermore, a partition is fixedly connected inside the conveying trough, and a servo motor connected to the controller signal is fixedly connected to both sides of the partition. The output shaft of each servo motor is coaxially fixedly connected to a first helical rod. A second helical rod is provided in each of the inclined conveying troughs, and a universal joint is fixedly connected between the first helical rod and the corresponding second helical rod.

[0023] Beneficial effects: The inclined conveying trough requires the screw rods to efficiently transmit power at different angles. The universal joint allows the two screw rods to flexibly transmit power in a non-linear state, ensuring that power is smoothly transmitted from the horizontal section to the inclined section of the conveying trough. The symmetrical double-helix structure makes the sludge more evenly stressed during the conveying process, avoiding deviation or blockage caused by unilateral stress, and is especially suitable for long-distance conveying of high-viscosity sludge.

[0024] Furthermore, the suction port has a flared, funnel-shaped structure at its edge, with the inlet end of the flared structure facing away from the sludge removal vehicle.

[0025] Beneficial effects: The flared, funnel-shaped structure with the larger end facing outwards significantly increases the coverage area of ​​the suction port, allowing sludge, water, and small impurities to enter the suction port more easily and quickly under negative pressure, reducing the number of times the sludge removal vehicle needs to move and improving operational efficiency.

[0026] Furthermore, a fixing ring is provided on the upper ring of the suction port. An electromagnet connected to the controller signal is provided on one side of the fixing ring. Several telescopic magnetic rods are fixedly connected to the side of the fixing ring opposite to the electromagnet.

[0027] Beneficial effects: When the pressure sensor detects abnormal resistance, the controller triggers the electromagnet to be energized, generating a magnetic field that attracts the telescopic magnetic rod to extend and adhere, forming an interception barrier to prevent large impurities with a diameter exceeding the gap from entering the suction port, thus avoiding pipe blockage or pump damage.

[0028] Furthermore, all telescopic magnetic rods are parallel to each other, and the gap width between adjacent telescopic magnetic rods is 2 to 5 cm.

[0029] Beneficial effects: The 2-5cm gap width design intercepts dangerous impurities while allowing silt and small particles to pass through smoothly, balancing the interception effect with the suction efficiency.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] As attached Figure 1 As shown: Existing sludge cleaning vehicles 1 often experience clogging of the suction port due to large impurities when using high-pressure water guns to clean and absorb sludge. Furthermore, the fixed nozzle diameter of the high-pressure water gun prevents the water flow rate from adaptively adjusting to the amount of impurities, resulting in low flushing efficiency and frequent jamming during the sludge cleaning process. Therefore, a convenient intelligent sludge cleaning device is proposed, comprising a sludge cleaning vehicle 1. The sludge cleaning vehicle 1 contains a controller, preferably a Siemens SIMATIC S7-1200 CPU controller. 1214C, the front end of the sludge dredging vehicle 1 is equipped with a working component for dispersing sludge, and the bottom of the sludge dredging vehicle 1 is connected to a suction component for adsorbing and filtering sludge. The working component is connected to the suction component. The working component includes a transverse shovel 2, and a high-pressure water gun is connected to the side of the transverse shovel 2 closest to the sludge dredging vehicle 1. The operator injects water into the transverse shovel 2 by activating the high-pressure water gun. The transverse shovel 2 is equipped with a fixed perforated plate 6 and symmetrically arranged movable perforated plates 3. The fixed perforated plate 6 and the movable perforated plate 3 are respectively provided with a number of first holes 7 and second holes 4, and the diameter of the first holes 7 is larger than the diameter of the second holes 4. The water flows through the first holes 7 and the second holes 4 and is sprayed out mixed. The fixed perforated plate 6 is fixedly connected to the transverse shovel 2, and the movable perforated plate 3 is connected to the second holes 4. Each plate 3 is hinged with a shovel plate 5. The angle of movement between the shovel plate 5 and the movable orifice plate 3 is 90° to 120°. The top and bottom of the shovel plate 5 are hinged with sliding components. The sliding components are used to drive the movable orifice plate 3 to slide in the transverse shovel groove 2 according to the resistance when the shovel plate 5 cleans the sludge. This causes the second hole 4 and the first hole 7 between the movable orifice plate 3 and the fixed orifice plate 6 to be misaligned, thereby creating a flow rate difference in the water output of the high-pressure water gun. In the initial state, the resistance of the sludge to the shovel plate 5 is kept within the movable range of the shovel plate 5 (90° to 120°). At this time, the shovel plate 5 does not trigger the sliding components. When the shovel plate 5 comes into contact with large pieces of sludge or large impurities such as stones or branches, the resistance is transmitted to the sliding components through the shovel plate 5.

[0042] Specifically, each sliding component includes a groove 8 and a slider 9. The groove 8 is respectively opened on the top and bottom walls of the transverse shovel groove 2. The slider 9 slides in conjunction with the groove 8. A connecting rod is hinged between the slider 9 and the shovel plate 5. The slider 9 is fixedly connected to the movable perforated plate 3. A telescopic rod 10 is fixedly connected to each slider 9. A spring 11 is coaxially sleeved on each telescopic rod 10. The two ends of the spring 11 are fixedly connected to the side walls of the slider 9 and the groove 8, respectively. By squeezing the shovel plate 5 with a force outside its movable range through large pieces of silt and large impurities, the slider 9 slides in the groove 8 and drives the movable perforated plate 3 to move along the transverse shovel groove 2. At this time, the first hole 7 and the second hole 4 gradually misalign (as shown in the attached figure). Figure 2 As shown, since the diameter of the second hole 4 is smaller than that of the first hole 7, the overlapping area is reduced after misalignment. This reduces the effective cross-sectional area of ​​the water outlet. Based on fluid mechanics principles, a decrease in cross-sectional area leads to an increase in flow velocity when the flow rate remains constant. Therefore, when the first hole 7 and the second hole 4 are misaligned, the diameter through which the water can flow decreases, resulting in an automatic increase in water velocity. The outer periphery of the second hole 4 is equipped with guide slopes, each forming an angle of 30° to 60° with the central axis of the second hole 4. High-speed water flows through these guide slopes and sprays to both sides, flushing large debris to both sides of the sludge removal vehicle 1, preventing blockage of the suction port 12. Simultaneously, the shovel plate 5 can rotate around the hinge of the movable perforated plate 3, working in conjunction with the water flow to impact and break up the plated sludge, improving cleaning efficiency.

[0043] Example 2:

[0044] As attached Figure 3As shown, the difference from Embodiment 1 is that the sludge suction assembly includes a sludge suction port 12, which is connected to the bottom of the sludge removal vehicle 1. The edge of the sludge suction port 12 has a funnel-shaped flared structure, and the entrance end of the flared structure faces away from the sludge removal vehicle 1. The funnel-shaped flared structure expands the sludge intake range, allowing sludge, water, and small impurities to quickly enter the sludge suction port 12. The inner wall of the sludge suction port 12 is provided with a transverse conveying groove 17, and the bottom of the conveying groove 17 is provided with several screen holes 16. Impurities with a diameter larger than the screen holes 16 can be filtered through the screen holes 16. Both sides of the conveying trough 17 extend obliquely to the outside of the suction port 12 and communicate with both sides of the sludge removal vehicle 1. A partition 18 is fixedly connected inside the conveying trough 17. Servo motors connected to the controller are fixedly connected to both sides of the partition 18. The input terminals of the servo motors are connected to the output terminals of the controller. The servo motors are preferably RE35 brushless DC motors. A first helical rod 15 is coaxially fixedly connected to the output shaft of each servo motor. A second helical rod 13 is provided inside each oblique conveying trough 17. A universal joint 14 is fixedly connected between the first helical rod 15 and the corresponding second helical rod 13. The first helical rod 15 is connected to the second helical rod 13 inside the oblique conveying trough 17 through the universal joint 14. The universal joint 14 allows the two helical rods to move flexibly at an oblique angle, adapting to the inclined structure of the conveying trough 17. Driven by the servo motors, the first helical rod 15 and the second helical rod 13 rotate. After the sludge enters the conveying trough 17, the first helical rod 15 and the second helical rod 13 form a continuous spiral thrust, conveying the sludge into the sludge removal vehicle.

[0045] Example 3:

[0046] As attached Figure 4 As shown, the difference from Embodiment 2 is that each of the shovel plates 5 is equipped with a pressure sensor that is connected to the controller signal. The output end of the pressure sensor is connected to the input end of the controller signal. The preferred model of the pressure sensor is Honeywell FSR-402. The pressure sensor monitors the resistance of the sludge or impurities on the shovel plate 5 in real time. When the shovel plate 5 contacts the plated sludge or large impurities, the pressure sensor detects that the resistance value exceeds the threshold and immediately sends a pressure electrical signal to the controller.

[0047] The suction port 12 is equipped with a fixing ring 19. An electromagnet 21, connected to the controller, is located on one side of the fixing ring 19. The input end of the electromagnet 21 is connected to the output end of the controller. The preferred model of the electromagnet 21 is a MAC 2450 electromagnet. Several telescopic magnetic rods 20 are fixedly connected to the side of the fixing ring 19 opposite to the electromagnet 21. The telescopic magnetic rods 20 are parallel to each other, and the gap between adjacent telescopic magnetic rods is 2–5 cm. When the controller sends an interception electrical signal, the electromagnet 21 is energized and generates a magnetic field, attracting the telescopic magnetic rods 20 to retract towards the electromagnet 21. The telescopic magnetic rods 20 simultaneously extend until they are attracted and fixedly connected to the side of the fixing ring 19 closest to the electromagnet 21, forming an interception barrier to prevent large impurities or hardened sludge from entering the suction port 12.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
