Description

Technical Field

[0001] This invention relates to the field of special vehicle technology, and in particular to an adaptive sludge suction device for dredging vehicles. Background Technology

[0002] Dredging vehicles are special vehicles used for municipal environmental sanitation operations. Dredging and vacuum trucks typically employ a vacuum negative pressure principle, using a vacuum pump to create negative pressure in the tank, utilizing atmospheric pressure differences to achieve the suction and discharge of waste. They are suitable for routine cleaning scenarios involving sewage and sludge. Existing vacuum devices primarily function to suction sewage, with minimal dredging capabilities. These devices typically use a suction pipe to draw sewage and sludge from the sewer pipe into the tank. The tank separates the mud and water, and the separated sewage is then pressurized and discharged back into the sewer system via the suction pipe.

[0003] In municipal maintenance, existing vacuum systems have significant drawbacks when handling highly viscous grease or solid impurities such as plastic and stones. Grease tends to form an adhesive layer on the inner wall of the pipe, increasing resistance, while large solid impurities can clog pipes or filters, or even burn out the motor. In such cases, suction and discharge efficiency drops sharply, and frequent shutdowns for cleaning significantly increase maintenance costs and severely restrict continuous operation. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Before providing a further detailed description of the embodiments of the present invention, the directional terms used in the embodiments of the present invention, such as "upper part", "lower part" and "side part", are not intended to limit the scope of protection of the present invention.

[0023] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 15 As shown, one embodiment of the present invention provides an adaptive sludge suction device for a dredging vehicle, the adaptive sludge suction device comprising: The pipe opening adjustment module is located at the second end of the rigid suction pipe 10, and the opening state of the pipe opening adjustment module is adjusted according to the dryness and wetness of the sludge. The debris roller cleaning module is configured to move between the front side of the first end of the rigid suction pipe 10 and both sides of the rigid suction pipe 10. The rotary cutter working auxiliary module is connected to the debris rotary cutter cleaning module, and the rotary cutter working auxiliary module is located on both sides of the rigid suction pipe 10. The rotary cutter working auxiliary module is configured to control the movement of the debris rotary cutter cleaning module.

[0025] The adaptive suction device includes a pipe opening adjustment module, a debris roller cleaning module, and a roller working auxiliary module. The pipe opening adjustment module is located at one end of the rigid suction pipe 10. The size of the pipe opening adjustment module can be adjusted according to the dryness or wetness of the sludge to accommodate the cleaning of sludge with different dryness or wetness. At the same time, controlled by the roller working auxiliary module, the debris roller cleaning module moves between the front side of the first end of the rigid suction pipe 10 and between the two sides of the rigid suction pipe 10. This can crush solid impurities such as weeds, fabrics, plastics, and stones in the pipe, preventing large pieces of impurities and linear impurities from jamming the pipe or clogging the filter screen, thus improving the stability and reliability of the adaptive suction device. The adaptive suction device of this application can adapt to the continuous operation requirements of complex working conditions and has good applicability in extreme weather conditions, thus improving the applicability range of the adaptive suction device.

[0026] It should be noted that this application is a vehicle-mounted module design for a dredging vehicle. A rigid suction pipe 10 is connected to the front end of the dredging vehicle's tank and installed at the end of the pipeline. During operation, power is provided by the dredging vehicle's hydraulic system, and the adaptive suction device of this application is extended entirely into the underground water pipe via the dredging vehicle's telescopic boom. This application is applicable to municipal drainage networks, circular or rectangular underground water pipes with a diameter of approximately 500 mm, and a vertical depth of approximately 8 meters.

[0027] It is understandable that the front side of the first end refers to the side of the rigid suction pipe 10 away from the pipe opening adjustment module, that is... Figure 1 On the left side, the rigid suction pipe 10 has only two sides. Figure 2 The location is shown in the diagram.

[0028] In one feasible implementation, the adaptive sludge suction device further includes a data acquisition and analysis module comprising: an acquisition unit and an analysis and control unit. The acquisition unit acquires image information of the sewer pipe, and the image information is transmitted to the analysis and control unit to obtain analysis results. Based on the analysis results, the operation of the pipe opening adjustment module, the debris roller cleaning module, and the roller working auxiliary module is controlled. The analysis results include the dryness and wetness of the sludge.

[0029] The data acquisition and analysis module captures images of the pipe's interior through its acquisition unit, comparing these images with the sludge type in the analysis and control unit to determine the sludge's type and moisture level. Based on this information, the analysis and control unit then controls the operation of the pipe adjustment module, the debris rolling cleaning module, and the roller cutter auxiliary module. In other words, as... Figures 1 to 3As shown, the data acquisition and analysis module, using data acquisition, analysis and control technology, can acquire images of the underground water pipes in a timely manner and analyze the dryness and wetness of the sludge. It can also adjust the collaborative work of each module in a timely manner, making the operation more convenient and further protecting the safety of operators in the harsh environment of municipal underground water pipes.

[0030] It should be noted that the analysis and control unit can learn from the characteristics of different types of sludge and the degree of dryness and wetness of sludge, and then be programmed. This is a commonly used form of analysis and comparison, which will not be elaborated further.

[0031] In one feasible implementation, the acquisition unit includes an industrial camera 1 and a supplementary light 2 mounted on the industrial camera 1, with the industrial camera 1 mounted on the nozzle adjustment module.

[0032] Specifically, through intelligent sensing (data acquisition and analysis module) and dynamic adjustment technology, the industrial camera 1 collects the composition and humidity of the sludge in the pipeline, and adjusts the opening size of the pipe outlet adjustment module in conjunction with the roller cutter working auxiliary module to control the working mode of the debris roller cutter cleaning module. The debris roller cutter cleaning module crushes solid impurities such as weeds, fabrics, plastics and stones. The adaptive sludge suction device of this application realizes the needs of automated underwater real-time survey, debris crushing and sludge cleaning, adapts to the continuous operation needs of complex working conditions, provides effective sludge suction support for dredging vehicles, and also has better application prospects in extreme rainy weather or disaster conditions.

[0033] Among them, such as Figure 3 As shown, the industrial camera 1 acquires a video stream, which is then transmitted to the analysis and control unit for image analysis to determine whether the sludge is wet. If the sludge is not wet enough, water can be sprayed through a high-pressure nozzle to humidify the sludge, facilitating the operation of the adaptive suction device. If the sludge wetness meets the requirements, the video stream is then used to determine if there are large objects. If large objects are present, the pipe opening adjustment module is controlled to increase the opening size, and the roller cutter working auxiliary module controls the debris roller cutter cleaning module to move to the front of the first end of the rigid suction pipe 10, at which point the debris roller cutter cleaning module begins to work. If there are no large objects, the pipe opening adjustment module can be controlled to decrease the opening size, and suction can be performed directly until the suction work is completed.

[0034] In one feasible implementation, the nozzle adjustment module includes: The first fixed plate 3 has a first through hole at its center and a plurality of first sliding grooves 301 evenly distributed on the outer periphery of the first through hole; The second fixed plate 8 covers the first fixed plate 3, and the second fixed plate 8 is fixedly connected to one end of the rigid suction pipe 10. A rotating disk 4 is disposed between a first fixed disk 3 and a second fixed disk 8. A second through hole is provided at the center of the rotating disk 4, and a plurality of second sliding grooves 401 are evenly provided on the outer periphery of the second through hole. An adjusting block 5 is disposed between the first fixed disk 3 and the rotating disk 4. A slider 501 is provided on the side of the adjusting block 5 facing the rotating disk 4. The slider 501 is configured to move within the second slide groove 401. A cylindrical pin 502 is provided on the side of the adjusting block 5 facing the first fixed disk 3. The first cylindrical pin 502 is configured to move within the first slide groove 301. When the cylindrical pin 502 is located at the end of the first slide groove 301 away from the first through hole, and the slider 501 is located at the end of the second slide groove 401 away from the second through hole, the pipe opening of the pipe opening adjustment module is at its maximum.

[0035] It should be noted that, as Figures 4 to 7 As shown, the pipe adjustment module is fixedly installed at the second end, i.e., the end, of the rigid suction pipe 10. The bottom of the first fixed plate 3 has a straight first groove 301. The rotating plate 4 is located inside the first fixed plate 3, and the rotating plate 4 has a straight second groove 401. The first groove 301 is inclined to the first through hole, and the second groove 401 is inclined to the second through hole, with opposite inclination directions. The adjustment block 5 is located between the first fixed plate 3 and the rotating plate 4. The adjustment block 5 has sliders 501 and cylindrical pins 502 on both sides in the thickness direction. The sliders 501 and second grooves 401 are slidably connected, and the cylindrical pins 502 are slidably connected to the first groove 301. The first through hole and the second through hole are interconnected and of the same size. When the rotating plate rotates (e.g., when the first through hole is open to the second through hole, the second through hole is closed to the second through hole, and ... Figure 5 (Rotating clockwise), the rotating disk drives the adjusting block 5 to rotate. At this time, the slider 501 moves within the second slide groove 401, and simultaneously the cylindrical pin 502 moves within the first slide groove 301. Multiple adjusting blocks 5 rotate in the opposite direction away from the first through hole (second through hole), exposing the entire first and second through holes, as shown... Figure 5 As shown, the opening of the pipe adjustment module is at its maximum at this time, which is suitable for underground water pipes containing large solid debris; when the rotating disc rotates in the opposite direction (such as...), Figure 5 (When the pointer rotates counterclockwise), the rotating disk drives the adjusting block 5 to rotate, causing two adjacent adjusting blocks 5 to fit together, and some adjusting blocks 5 to close the first and second through holes, such as... Figure 6 As shown, the opening of the pipe adjustment module is at its smallest at this time, which is suitable for situations where there are no large particles of debris in the underground water pipe.

[0036] Understandably, when the opening of the pipe orifice adjustment module is at its smallest, multiple adjustment blocks 5 are closed, adjacent adjustment blocks 5 are in contact, and the multiple adjustment blocks 5 form a circular opening. The diameter of this circular opening is smaller than the diameter of the first through hole. In other words, under the action of the driving component 6, the adjustment blocks 5 rotate around their respective rotation centers and move within the first slide groove 301 and the second slide groove 401, thereby achieving the adjustment of the pipe orifice size of the pipe orifice adjustment module. For example, the arrangement of the second fixed plate 8 can enclose the rotating plate 4 and the adjusting block 5 in a space, improving the safety and reliability of the working environment of the rotating plate 4 and the adjusting block 5, thereby increasing the service life of the adaptive suction device and extending maintenance time.

[0037] In one feasible embodiment, at least a portion of the outer periphery of the rotating disk 4 is provided with driven teeth 402, and limit blocks 403 are provided on both sides of the driven teeth 402. The first fixed disk 3 is provided with a notch, and the pipe adjustment module further includes: The driving component 6 is fixedly mounted on the first fixed disk 3, and the output shaft of the driving component 6 is provided with a drive gear 7; Among them, the driven tooth 402 and the limiting block 403 pass through the notch, and the driven tooth 402 meshes with the driving gear 7.

[0038] It should be noted that, as Figure 7 As shown, the outer periphery of the rotating disk 4 is provided with arc-shaped driven teeth 402, and limit blocks 403 are provided at both ends of the driven teeth 402. At least part of the limit blocks 403 and the driven teeth 402 protrude from the notch. The drive gear 7 is connected to the output shaft of the drive member 6. The drive gear 7 meshes with the driven teeth 402. Under the power of the drive member 6, the rotating disk 4 can be driven to rotate, and then rotate with it through the second slide groove 401, realizing the movement of the slider 501 in the second slide groove 401, driving the rotation of the adjusting block 5, and the cylindrical pin 502 moves in the first slide groove 301. The first fixed disk 3 achieves the limitation of the adjusting block 5. Understandably, the physical limiting method of the limiting block 403 can prevent the rotating disk 4 from rotating excessively, avoid damage to the adaptive suction device due to overtravel, and ensure the safety and reliability of the adaptive suction device.

[0039] In one feasible implementation, the debris roller cleaning module includes: a roller body 20, a roller fastener, a fixed rotating shaft 21, a roller support frame 15, and a drive assembly. The roller body 20 is connected to the fixed rotating shaft 21 via the roller fastener, the roller support frame 15 is connected to the fixed rotating shaft 21 via a bearing 25, and the drive assembly is connected to the end of the fixed rotating shaft 21 away from the roller body 20.

[0040] Among them, such as Figures 13 to 15As shown, the debris cleaning module can clean solid impurities such as weeds, fabrics, plastics, and stones. When the debris particles are detected to be too large or there are many long strips of debris, the debris cleaning module can be positioned in front of the first end of the rigid suction pipe 10 to break up the debris before it enters the rigid suction pipe 10 through the first end and is then discharged through the pipe opening adjustment module. The drive component is used to control the rotation of the roller body 20, so that the outer blade of the roller body 20 can quickly cut up solid impurities. The roller support frame 15 is for subsequent connection with the roller working auxiliary module, so the roller support frame 15 needs to be fixed. Therefore, the roller support frame 15 needs to be connected to the fixed rotating shaft 21 through the bearing 25 to ensure that the roller body 20 rotates while the roller support frame 15 is in a fixed position.

[0041] In one feasible embodiment, the hob body 20 is provided with a mounting hole, and the inner wall of the hob body 20 is provided with a hob fixing groove 2001. The hob fastener includes: Fastening seat 22 is provided in the mounting hole. The fastening seat 22 is provided with mounting groove 2201. Guide block 2202 is provided between adjacent mounting grooves 2201. Guide groove 2203 is provided at the center of mounting groove 2201. T-block 24 and rubber fastener 23 are provided in the mounting groove 2201; T-block 24 is set in T-block rubber fastener 23, and one end of T-block 24 is inserted into guide groove 2203 and cutter fixing groove 2001 in sequence; A limiting strip 2101 is provided on the outer periphery of the fixed rotating shaft 21, and two adjacent T-shaped rubber fasteners 23 form a groove, with the limiting strip 2101 and the groove being interference fit.

[0042] Specifically, the hob body 20 is connected to the fixed rotating shaft 21 by hob fasteners. The hob support frame 15 is connected to the fixed rotating shaft 21 through a bearing 25. A sleeve 26 is provided between the bearing 25 and the hob body 20. The two ends of the bearing 25 and the hob support frame 15 are covered by bearing end caps 27 to prevent foreign objects from entering the bearing 25 and affecting the operation of the hob body 20. The setting of the sleeve 26 and the bearing end cap 27 is a common method and will not be described in detail here.

[0043] It should be noted that, as Figure 14 and Figure 15As shown, the hobbing cutter fastener includes a fastening base 22, a T-shaped rubber fastener 23, and a T-shaped block 24. The fastening base 22 has mounting holes for easy insertion of the rotating shaft 21. The inner wall of the fastening base 22 has mounting grooves 2201 for accommodating the T-shaped rubber fasteners 23. Guide blocks 2202 are provided between adjacent mounting grooves 2201 to separate adjacent T-shaped rubber fasteners 23. Each mounting groove 2201 has a guide groove 2203 at its center, aligned with the hobbing cutter fixing groove 2001. The T-shaped block 24 is installed within the T-shaped rubber fastener 23, with one end of the T-shaped block 24 passing through the guide groove 2203 and the hobbing cutter fixing groove 2001, thus achieving a fixed connection between the hobbing cutter fastener and the hobbing cutter body 20. Meanwhile, a groove is formed between adjacent T-shaped rubber fasteners 23, and a limiting strip 2101 is provided on the outer periphery of the fixed rotating shaft 21. The limiting strip 2101 corresponds to the size of the groove, thereby realizing the connection between the hob fastener and the fixed rotating shaft 21. In other words, the hob body 20 and the fixed rotating shaft 21 are fixedly connected by the hob fastener, so that the hob body 20 can rotate with the rotation of the fixed rotating shaft 21.

[0044] For example, the limiting strip 2101 is interference-fitted with the slot, and at least one of the T-block rubber fastener 23 and the limiting strip 2101 is made of elastic material. In this way, the compression of the elastic material achieves a fixed connection between the two, improving the stability of the connection. If neither of them is made of elastic material, a cold pressing or hot pressing process is required to achieve an interference fit connection.

[0045] In one feasible implementation, the driving component includes: Motor base 29 is located at the end of fixed shaft 21 away from hob body 20; The motor 28 is housed in the motor base 29, and the output shaft of the motor 28 is fixedly connected to the fixed rotating shaft 21 via the coupling 30.

[0046] The roller cutter body 20 is driven to rotate by a motor 28, which is mounted on a motor base 29. The other end of the motor base 29 is fixedly connected to the bearing end cover 27 and together with it is fixedly connected to the roller cutter support frame 15. The output shaft of the motor 28 passes through the motor base 29 and is fixedly connected to the fixed rotating shaft 21 through a coupling 30. The rotation of the motor 28 drives the rotation of the fixed rotating shaft 21, which in turn drives the roller cutter body 20 to rotate, thus realizing the cleaning work of large impurities by the impurity roller cutter cleaning module.

[0047] In one feasible implementation, the rigid suction pipe 10 is provided with first linear guide rails 11 on both sides, and the roller cutter working auxiliary module includes: The fixed base 12 is mounted on the first linear guide rail 11 via the first slider 13; The rotary cutter rotating gear shaft 14 is located at one end of the fixed base 12. Part of the debris rotary cutter cleaning module is fixedly connected to the rotary cutter rotating gear shaft 14, and gears are provided on the rotary cutter rotating gear shaft 14. The second linear guide 16 is located in the middle of the fixed base 12; The cylinder floating connector 17 includes a connector body and an extension block 1701 disposed on the connector body. The cylinder floating connector 17 also includes a connecting plate. A rack 1702 is provided on the side of the connecting plate facing the rigid suction pipe 10. The rack 1702 meshes with a gear. The extension block 1701 is connected to the second linear guide rail 16 through the second slider 18. Linear cylinder 19 is disposed on both sides of rigid suction pipe 10, and the telescopic end of linear cylinder 19 is fixedly connected to the connector body. The extension and retraction of the linear cylinder 19 causes the connecting plate to extend and retract, which in turn causes the gear meshing with the rack 1702 on the connecting plate to rotate, which in turn causes the hob rotating gear shaft 14 to rotate, thereby rotating the debris hob cleaning module which is fixedly connected to the hob rotating gear shaft 14.

[0048] Specifically, such as Figures 8 to 12 As shown, the hobbing cutter working auxiliary module is set on both sides of the rigid suction pipe 10. That is, the rigid suction pipe 10 has a first linear guide rail 11 on both sides, and the linear cylinder 19 is also set on both sides of the rigid suction pipe 10, and the fixed end of the linear cylinder 19 is connected to the end of the rigid suction pipe 10 away from the first linear guide rail 11. The fixed base 12 is fixedly connected to the first slider 13, the first slider 13 is set in the first linear guide rail 11, the two ends of the hobbing cutter rotating gear shaft 14 are provided with gears, and the end of the hobbing cutter rotating gear shaft 14 away from the gear is connected to the fixed base 12. The side of the hobbing cutter support frame 15 is fixedly connected to the hobbing cutter rotating gear shaft 14, and the hobbing cutter support frame 15 does not interfere with the gear. The fixed base 12 has a recess in its center, and a second linear guide rail 16 is provided in the recess. The connector body of the cylinder floating connector 17 is fixedly connected to the extended end of the linear cylinder 19. The extension block 1701 on the cylinder floating connector 17 is connected to the second linear guide rail 16 through a second slider 18. Figure 9 and Figure 13 As shown, the cylinder floating joint 17 has a connecting plate at one end away from the telescopic end of the linear cylinder 19. The connecting plate has a rack 1702, which is arranged along the length of the rigid suction pipe 10 and meshes with a gear.

[0049] It should be noted that by extending and retracting the linear cylinder 19, the fixed seat moves on the first linear guide rail 11, which in turn drives the cylinder floating joint 17 to move within the second linear guide rail 16. This causes the rack 1702 to move, which in turn drives the gear meshing with the rack 1702 to rotate. The hob rotating gear shaft 14 rotates with the gear, which in turn drives the hob support frame 15, which is fixedly connected to the hob rotating gear shaft 14, to rotate. This allows the two hob bodies 20 to rotate to both sides of the rigid suction pipe 10, that is, from Figure 10 Move to the position shown. Figure 11 The location is shown. It is understandable that when large particles or excessive linear impurities are detected, the linear cylinder 19 extends. At this time, the roller cutter auxiliary module drives the debris roller cutter cleaning module to the front of the first end of the rigid suction pipe 10, breaking up the large particles and linear impurities before they enter the pipe opening adjustment module through the rigid suction pipe 10 and are discharged. Conversely, the linear cylinder 19 retracts, and the roller cutter auxiliary module drives the debris roller cutter cleaning module to both sides of the rigid suction pipe 10, agitating the sludge in the underground water pipe to ensure good sludge flowability, facilitating its entry into the rigid suction pipe 10 and the pipe opening adjustment module before discharge.

[0050] In one feasible implementation, the adaptive suction device further includes: High-pressure nozzle 9 is mounted on the pipe adjustment module; The pipe inlet filter 31 is installed on the first end of the rigid suction pipe 10, and the pipe inlet adjustment module is installed on the second end of the rigid suction pipe 10.

[0051] Among them, such as Figure 1 As shown, mounting holes are provided on the side of the second fixed plate 8 and / or the first fixed plate 3 near the drive component 6. A high-pressure nozzle 9 is installed in the mounting hole, and liquid is sprayed through the high-pressure nozzle 9 to dilute the relatively dry sludge, improving the sludge dilution efficiency and facilitating the discharge of sludge by the adaptive suction device. Figure 2 As shown, a pipe filter 31 is provided at the end of the rigid suction pipe 10 furthest from the pipe opening adjustment module. This prevents excessively large particles from entering the rigid suction pipe 10, ensuring the service life of the adaptive suction device. Figure 3 As shown, video or images are acquired through industrial camera 1, and the background performs image classification to determine the sludge composition and sludge moisture content. When the sludge moisture content is low, water is sprayed through high-pressure nozzle 9. When large particulate impurities are detected, the opening of the pipe adjustment module is maximized. At the same time, the linear cylinder 19 of the roller cutter working auxiliary module extends, so that the debris roller cutter cleaning module is located in front of the rigid suction pipe 10 to crush the impurities first, improve the service life of the adaptive suction device, extend the maintenance interval of the adaptive suction device, and improve economy.

[0052] Specifically, such as Figures 1 to 15 As shown, firstly, the industrial camera 1 is illuminated by the supplementary light 2 inside the dark underground water pipe to facilitate the acquisition of image information of the municipal underground water pipe. The image information acquired by the industrial camera 1 is analyzed and calculated with the data in the big data in the analysis and control unit to obtain the dryness and wetness of the sludge and the condition of impurities in the municipal underground water pipe. When a dry sludge signal is received, the high-pressure nozzle 9 is controlled to spray high-pressure water to flush and disperse the dry sludge in the underground water pipe. Then, the industrial camera 1 collects image information. When wet sludge is obtained, it is determined whether there are large solid debris and a large number of linear debris. When there are large solid debris, the drive component 6 of the pipe opening adjustment module is controlled to rotate, which in turn controls the rotating disk 4 to rotate, driving the adjustment block 5 to rotate, so that the pipe opening is maximized. At the same time, after receiving the signal, the linear cylinder 19 of the roller cutter working auxiliary module extends the telescopic end, and the fixed base 12 moves forward along the first linear guide rail 11. When the first linear guide rail 11 reaches its maximum stroke, the cylinder floating joint 17 continues to move forward along the second linear guide rail 16. Then, the roller cutter rotating gear shaft 14 drives the roller cutter support frame 15 to rotate, rotating the debris roller cutter cleaning module to the front of the first end of the cleaned suction pipe. After receiving a signal, the motor 28 of the debris cleaning module starts working, driving the fixed rotating shaft 21 and the roller body 20 to rotate, thereby cleaning the debris. The debris that is not completely cleaned is intercepted by the pipe filter screen 31 and continues to be crushed by the roller body 20 until it passes through the pipe filter screen 31.
