A municipal road dredging equipment

Abstract

This invention relates to the field of dredging technology, specifically to a municipal road dredging device. It includes a movable base mounted on both sides of a ditch, with sliders mounted on top of each base. A truss is mounted on the base, and grooves corresponding to the sliders are located at both ends of the truss. The sliders slide in contact with the grooves. When the suction pipe draws sludge from the ditch into a sewage tank, a filter screen filters larger debris and other impurities from the sludge onto the screen, while smaller impurities, such as water, fall into the sewage tank through the screen. By activating a first motor, a first spiral shaft is driven to slide against the filter screen, squeezing the filtered impurities into a first discharge pipe, which then discharges the debris from the filter screen, thus performing the first cleaning of the drawn-out sludge and impurities.

Description

Technical Field

[0001] This invention relates to the field of dredging technology, specifically to a municipal road dredging device. Background Technology

[0002] Drainage channels are typically dug on both sides of the road to drain sewage and rainwater. Over time, the drainage of sewage and rainwater, as well as dust and waste generated on the road, will fall into the drainage channels. Therefore, municipal management needs to arrange for personnel to clean the drainage channels regularly to ensure normal drainage.

[0003] Currently, most ditch cleaning methods rely on manual labor or excavators to remove sludge. This method is not well-suited for ditches of varying widths, thus directly impacting the convenience of ditch cleaning. Therefore, a municipal road dredging device is proposed to facilitate the removal of sludge from ditches of different widths and improve dredging efficiency. Summary of the Invention

[0004] To address the problems in the existing technology, this invention provides a municipal road dredging device that facilitates the dredging of sludge in ditches of different widths, thereby improving dredging efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problem is a municipal road dredging equipment, including a mobile base set on both sides of a water channel, a slider respectively provided on the top of the mobile base, a truss provided on the mobile base, and a sliding groove corresponding to the slider at both ends of the truss, and the slider slidingly contacting the sliding groove;

[0006] The truss is equipped with a support frame, on which a sewage tank is installed. Several sets of sewage suction pipes are connected to the top side of the sewage tank, and a second sewage discharge pipe is connected to the bottom side of the sewage tank. A negative pressure machine is installed on the top of the sewage tank.

[0007] By adopting the above technical solution, when it is necessary to clean the water channel, the number and position of the sewage suction pipes can be adjusted according to the width of the water channel by placing the mobile base on both sides of the water channel and relying on the sliding contact between the sliding groove on the truss and the slider on the mobile base.

[0008] When the sewage suction pipe is adjusted to the appropriate position and placed in the water channel, the negative pressure machine is turned on to generate negative pressure in the sewage suction pipe. When negative pressure is generated in the sewage suction pipe, the sewage suction pipe is used to suck up the sludge and other substances in the water channel and suck them into the sewage tank. At the same time, the second sewage discharge pipe is used to discharge the sludge and other substances in the sewage tank to one side of the water channel.

[0009] By moving the mobile base on both sides of the water channel, the second sewage pipe can be moved synchronously. The movement of the mobile base allows the suction pipe to move and pump the silt from the water channel, thereby improving the cleaning efficiency of the water channel.

[0010] Specifically, the sewage suction pipe has a valve at one end near the sewage tank. The sewage tank has a filter screen corresponding to the sewage suction pipe inside. A first spiral shaft is provided between the filter screen and the sewage suction pipe. The bottom of the filter screen has an arc-shaped structure that cooperates with the first spiral shaft. A first drain pipe is connected to one side of the top of the sewage tank. One end of the first spiral shaft corresponds to the first drain pipe. One end of the first spiral shaft passes through the sewage tank and is rotatably connected to the sewage tank. A first drive wheel is connected to one end of the first spiral shaft. A first motor is provided on one side of the sewage tank. A first pulley is installed at the output end of the first motor. The first drive wheel is driven by the first drive belt and the first pulley. The first spiral shaft is in sliding contact with the filter screen.

[0011] By adopting the above technical solution, the number of sewage suction pipes used can be adjusted according to the width of the water channel by relying on the function of the valve.

[0012] When the sludge is pumped from the ditch into the sewage tank through the suction pipe, larger debris and other impurities in the sludge are filtered onto the filter screen, while smaller impurities such as water fall into the sewage tank through the filter screen. By turning on the first motor, the first pulley is driven to rotate, which in turn drives the first transmission belt to rotate. When the first transmission belt rotates, it drives the first transmission wheel to rotate, which in turn drives the first spiral shaft to rotate. Through the sliding contact between the first spiral shaft and the filter screen, the impurities filtered on the filter screen are squeezed into the first discharge pipe, and the debris on the filter screen is discharged through the first discharge pipe, thus performing the first cleaning of the pumped sludge and other impurities.

[0013] Specifically, the bottom of the sewage tank forms a downward slope, the first sewage pipe is located above the top of the slope, and the second sewage pipe is located at the bottom of the slope;

[0014] The sewage tank is provided with a second spiral shaft at the bottom inner side. One end of the second spiral shaft corresponds to the second sewage pipe, and the other end of the second spiral shaft passes through the sewage tank and is connected to the second transmission wheel. A second motor is provided on one side of the sewage tank. A second pulley is installed at the output end of the second motor. The second transmission wheel is driven by the second transmission belt and the second pulley. The second spiral shaft is rotatably connected to the sewage tank.

[0015] By adopting the above technical solution, when smaller impurities fall into the sewage tank through the filter screen, the impurities and sludge will settle at the bottom of the sewage tank. The second motor is turned on, and the second pulley is driven to rotate. When the second pulley rotates, it drives the second transmission belt to rotate. The rotation of the second transmission belt drives the second transmission wheel to rotate. When the second transmission wheel rotates, it drives the second spiral shaft to rotate. When the second spiral shaft rotates, it squeezes the sludge and impurities settled at the bottom of the sewage tank. When the sludge and impurities are squeezed to a certain position, they are discharged through the second sewage pipe, thus performing a second cleaning of the sludge and other impurities.

[0016] Specifically, one end of each of the several groups of suction pipes is connected to a suction structure;

[0017] The sludge extraction structure includes a sludge extraction shell, one end of which has an opening, and one end of the sludge extraction pipe is connected to the opening. The bottom of the sludge extraction shell has a sludge extraction port. The side of the sludge extraction shell away from the opening has a groove. A sliding plate is slidably connected in the groove. The sliding plate passes through the groove and slides in contact with the sludge extraction port. A baffle is connected to the upper surface of the sliding plate away from the sludge extraction shell. A return spring is connected between the baffle and the sludge extraction shell. A first roller is installed on the side of the sliding plate near the baffle. A vertically arranged support plate is connected to the side of the sliding plate away from the baffle. A second roller is connected to the lower end of the support plate.

[0018] By adopting the above technical solution, when cleaning the water channel, the sludge suction pipe is connected to the sludge suction structure, the negative pressure machine is turned on, and the sludge suction shell is placed into the water channel. When the moving base moves, it drives the sludge suction pipe to move, and when the sludge suction pipe moves, it drives the sludge suction shell to move. Due to the silt accumulated in the water channel, it generates a squeezing force on the support plate. When the support plate is squeezed, it drives the sliding plate to slide in the chute and opens the sludge suction port. When the sludge suction port is open, the negative pressure machine drives the sludge suction pipe to suck up the silt and impurities in the water channel. At the same time, when the sliding plate moves, it drives the return spring to compress.

[0019] The more silt and impurities in the canal, the greater the resistance the suction structure experiences as it moves, resulting in greater pressure on the support plate and a longer distance the sliding plate moves. This greater distance allows for a larger opening in the suction port, thus improving the efficiency of cleaning the silt and impurities from the canal. Conversely, when the amount of silt and impurities is small, the pressure on the support plate is less, resulting in a smaller suction opening.

[0020] Because the silt and impurities in the canal are unevenly distributed, the amount of silt on the left and right sides of the canal will be inconsistent during the cleaning process. When one set of suction pipes is suctioning and there is less silt in one area, while the other set of suction pipes is suctioning and there is more silt, the sliding plate of the suction shell with less silt moves a shorter distance and the suction port opens smaller. For the suction shell with more silt, the suction port opens larger. At this time, the suction force generated by the negative pressure machine will act more on the suction pipe with more silt, thereby increasing the suction force in the area with more silt. In this way, the suction force of different suction pipes can be automatically adjusted according to the distribution of silt and impurities in the canal.

[0021] The first and second rollers facilitate the movement of the sludge suction shell within the water channel.

[0022] It should be noted that, due to the large mass of the silt, the support plate can be squeezed by moving the base; however, when the silt and impurities have been completely pumped out, the water in the channel is insufficient to squeeze and move the support plate. Thus, the reset spring drives the slide plate to slide and reset in the groove to close the corresponding sewage suction pipe.

[0023] Specifically, the first drain pipe is provided with a first check valve at the end near the first spiral shaft, and the second drain pipe is provided with a second check valve at the end near the second spiral shaft.

[0024] By adopting the above technical solution, relying on the function of the first one-way valve and the second one-way valve, water can be prevented from being discharged through the first and second sewage pipes; only when the first and second spiral shafts rotate, squeezing silt and other impurities into the first and second sewage pipes, can the first and second one-way valves be opened by the rotation and squeezing of the first and second spiral shafts, and the silt and impurities be discharged.

[0025] Specifically, each slider is fitted with a sliding sleeve at its upper end, and each slide groove is provided with a telescopic rod on the side near the slider, with the telescopic end of the telescopic rod connected to the sliding sleeve.

[0026] By adopting the above technical solution, the mobile base is placed on both sides of the water channel, and the telescopic rod is adjusted. When the telescopic rod moves, the position of the sewage tank on the truss can be adjusted to correspond to the width of the water channel, thus facilitating the cleaning of water channels of different widths.

[0027] Specifically, each side of the mobile base is equipped with a set of electric steering drive wheels and a set of support wheels.

[0028] By adopting the above technical solution, relying on the electric steering drive wheel and support wheel, it is easy to drive the mobile base to move in coordination with both sides of the water channel. By moving the mobile base, it is possible to move while simultaneously pumping and cleaning the silt in the water channel.

[0029] Specifically, a water pump is installed on the side of the sewage tank away from the sewage suction pipe, the water pump is connected to the sewage tank, and a drain pipe is installed on one side of the water pump, the drain pipe is connected to the water pump.

[0030] By adopting the above technical solution, the water in the sewage tank can be discharged through the drain pipe by turning on the water pump, which improves the convenience of cleaning the water channel.

[0031] Specifically, the sludge suction shell has a cavity on the side near the spring, and a double-threaded transmission rod is installed in the cavity. The two ends of the double-threaded transmission rod are rotatably connected to the inner wall of the cavity. A transmission gear is connected to the middle of the double-threaded transmission rod. Two sets of rotating shafts are rotatably connected to the side of the sludge suction shell near the spring. One end of each rotating shaft passes through the sludge suction shell and is placed inside the cavity. A driven gear is connected to the end of the rotating shaft inside the cavity. The two sets of driven gears mesh with the double-threaded transmission rod respectively. A plug rod is connected to the end of the rotating shaft away from the driven gear. A toothed structure is provided on the side of the slide plate near the cavity. A notch corresponding to the toothed structure is provided on the upper inner side of the slot. The transmission gear meshes with the toothed structure.

[0032] By adopting the above technical solution, when there is a large amount of silt in the canal, in order to prevent the mobile base from continuing to move before the silt has been completely pumped out, when the slide plate moves, the tooth structure on one side of the slide plate meshes with the transmission gear to drive the double-threaded transmission rod to rotate. When the double-threaded transmission rod rotates, it drives the driven gear to rotate, thereby driving the rotating shaft to rotate, and thus driving the insertion rod to rotate towards the bottom of the canal. When the slide plate moves to its limit, the insertion rod is pressed against the bottom of the canal, and the insertion rod can prevent the mobile base from continuing to move.

[0033] After the silt and other debris are removed, the return spring drives the slide plate to move back to its original position. When the slide plate moves, the tooth structure meshes with the transmission gear, thereby driving the double-threaded transmission rod to return to its original position. When the double-threaded transmission rod returns to its original position, it drives the insertion rod to return to its original position. At this time, the moving base can continue to move to pump and clean the water channel.

[0034] The beneficial effects of this invention are:

[0035] (1) The municipal road dredging equipment of the present invention, when the sludge in the ditch is pumped into the sewage tank by the sludge suction pipe, the larger garbage and other impurities in the sludge are filtered on the filter screen, while some smaller impurities such as water fall into the sewage tank through the filter screen. By turning on the first motor, the first spiral shaft is driven to slide into the filter screen, and the impurities filtered on the filter screen are squeezed into the first sewage pipe. The garbage on the filter screen is discharged through the first sewage pipe, thereby cleaning the sludge and other impurities that are pumped in for the first time.

[0036] (2) The municipal road dredging equipment of the present invention, when small impurities fall into the sewage tank through the filter screen, the impurities and sludge will sink to the bottom of the sewage tank. The second motor is turned on to drive the second spiral shaft to rotate, and the sludge and impurities sinking to the bottom of the sewage tank are squeezed. When the sludge and impurities are squeezed to a certain position, they are discharged through the second sewage pipe, thereby cleaning the sludge and the like for the second time.

[0037] (3) The municipal road dredging equipment described in this invention, when there is more silt and impurities in the water channel, the resistance to the dredging structure is greater when the dredging structure moves, the pressure on the support plate is greater, and the sliding plate moves to a larger position. When the sliding plate moves to a larger position, the size of the dredging port is larger, thereby improving the cleaning efficiency of silt and impurities in the water channel; conversely, when the silt and impurities are smaller, the pressure on the support plate is smaller, thereby reducing the suction size of the dredging port.

[0038] (4) The municipal road dredging equipment described in this invention addresses the uneven distribution of silt and impurities in the water channel. During the dredging process, the amount of silt on the left and right sides of the water channel will be inconsistent. When one set of suction pipes is suctioning and there is less silt at one location, while the other set of suction pipes is suctioning and there is more silt at another location, the suction shell with less silt will be driven by a set of sliding plates to move in the chute by the action of a return spring. The movement of the sliding plates will drive the support plate to move, causing the return spring to rebound and the suction port to shrink. For the suction shell with more silt, the suction port will be enlarged. In this way, the suction force of different suction pipes can be automatically adjusted according to the distribution of silt and impurities in the water channel.

[0039] (5) The municipal road dredging equipment of the present invention, in order to prevent the mobile base from continuing to move after the sludge suction pipe has finished suctioning the sludge, etc., relies on the sliding plate to slide in the trough. When the sliding plate moves, it relies on the tooth structure provided on one side of the sliding plate to mesh with the double-headed threaded transmission rod for transmission. When the double-headed threaded transmission rod rotates, it drives the L-shaped insert rod to move. When the sliding plate moves to the limit, the L-shaped insert rod abuts against the surface of the water channel. The L-shaped insert rod can prevent the mobile base from continuing to move.

[0050] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0051] To facilitate the dredging of sludge in the canal and improve dredging efficiency, as one embodiment of the present invention, such as... Figure 1 , Figure 2 As shown, the municipal road dredging equipment of the present invention includes a mobile base 2 set on both sides of a water channel 1, a slider 3 respectively provided on the top of the mobile base 2, a truss 4 provided on the mobile base 2, and a sliding groove 5 corresponding to the slider 3 provided at both ends of the truss 4, and the slider 3 slidingly contacts the sliding groove 5.

[0052] The truss 4 is provided with a support 6, and a sewage tank 7 is installed on the support 6. Several sets of sewage suction pipes 8 are connected to the top side of the sewage tank 7, and a second sewage discharge pipe 9 is connected to the bottom side of the sewage tank 7. A negative pressure machine 10 is provided on the top of the sewage tank 7.

[0053] When cleaning the water channel 1, the number and position of the sewage suction pipes 8 can be adjusted according to the width of the water channel 1 by placing the mobile base 2 on both sides of the water channel 1 and relying on the sliding contact between the sliding groove 5 on the truss 4 and the slider 3 on the mobile base 2.

[0054] When the sludge suction pipe 8 is adjusted to the appropriate position and placed in the water channel 1, the negative pressure machine 10 is turned on, and the negative pressure machine 10 generates negative pressure in the sludge suction pipe 8. When negative pressure is generated in the sludge suction pipe 8, the sludge and other materials in the water channel 1 are sucked out by the sludge suction pipe 8 and sucked into the sewage tank 7. At the same time, the sludge and other materials in the sewage tank 7 are discharged to one side of the water channel 1 by the second sewage discharge pipe 9.

[0055] The mobile base 2 moves on both sides of the water channel 1, allowing the suction pipe 8 to move and suck up the silt in the water channel 1, thereby improving the cleaning efficiency of the water channel 1.

[0056] To facilitate the cleaning of pumped-out sludge and impurities, for example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention further includes a valve 11 at one end of the sludge suction pipe 8 near the sewage tank 7, a filter screen 12 corresponding to the sludge suction pipe 8 inside the sewage tank 7, a first spiral shaft 13 between the filter screen 12 and the sludge suction pipe 8, the bottom of the filter screen 12 having an arc-shaped structure that cooperates with the first spiral shaft 13, a first drain pipe 17 connected to one side of the top of the sewage tank 7, one end of the first spiral shaft 13 corresponding to the first drain pipe 17, one end of the first spiral shaft 13 passing through the sewage tank 7 and rotatably connected to the sewage tank 7, one end of the first spiral shaft 13 being connected to a first transmission wheel 14, a first motor 16 provided on one side of the sewage tank 7, a first pulley 18 installed at the output end of the first motor 16, the first transmission wheel 14 being driven by the first transmission belt 15 and the first spiral shaft 13 slidingly contacting the filter screen 12.

[0057] When in use, the number of sewage suction pipes 8 can be adjusted according to the width of the water channel 1 by relying on the function of valve 11.

[0058] When the sludge is pumped from the ditch 1 into the sewage tank 7 by the suction pipe 8, larger debris and other impurities in the sludge are filtered onto the filter screen 12, while smaller impurities such as water fall into the sewage tank 7 through the filter screen 12. By turning on the first motor 16, the first motor 16 drives the first pulley 18 to rotate, which in turn drives the first transmission belt 15 to rotate. When the first transmission belt 15 rotates, it drives the first transmission wheel 14 to rotate, which in turn drives the first spiral shaft 13 to rotate. Through the sliding contact between the first spiral shaft 13 and the filter screen 12, the impurities filtered on the filter screen 12 are squeezed into the first drain pipe 17, and the debris on the filter screen 12 is discharged through the first drain pipe 17, thus performing the first cleaning of the pumped sludge and other impurities.

[0059] To further clean the pumped-out sludge and impurities, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a downward slope formed at the bottom of the sewage tank 7, with the first sewage pipe 17 located above the top of the slope and the second sewage pipe 9 located at the bottom of the slope;

[0060] The sewage tank 7 has a second spiral shaft 19 at its inner bottom. One end of the second spiral shaft 19 corresponds to the second sewage pipe 9, and the other end of the second spiral shaft 19 passes through the sewage tank 7 and is connected to the second transmission wheel 20. A second motor 22 is provided on one side of the sewage tank 7. A second pulley 23 is installed at the output end of the second motor 22. The second transmission wheel 20 is driven by the second transmission belt 21 and the second pulley 23. The second spiral shaft 19 is rotatably connected to the sewage tank 7.

[0061] In use, when smaller impurities fall into the sewage tank 7 through the filter screen 12, the impurities and sludge will settle at the bottom of the sewage tank 7. The second motor 22 is turned on, and the second pulley 23 is driven to rotate. When the second pulley 23 rotates, it drives the second transmission belt 21 to rotate. The rotation of the second transmission belt 21 drives the second transmission wheel 20 to rotate. When the second transmission wheel 20 rotates, it drives the second spiral shaft 19 to rotate. When the second spiral shaft 19 rotates, it squeezes the sludge and impurities settled at the bottom of the sewage tank 7. When the sludge and impurities are squeezed to a certain position, they are discharged through the second drain pipe 9, thus performing a second cleaning of the sludge, etc.

[0062] To facilitate automatic adjustment of the suction force of different suction pipes 8, such as Figures 2 to 5 As shown, the present invention also includes a sludge suction structure at one end of each of the several sets of sludge suction pipes 8.

[0063] The sludge extraction structure includes a sludge extraction shell 24, one end of which has an opening 25. One end of the sludge extraction pipe 8 is connected to the opening 25. The bottom of the sludge extraction shell 24 has a sludge extraction port 26. A groove 27 is provided on the side of the sludge extraction shell 24 away from the opening 25. A sliding plate 28 is slidably connected in the groove 27. The sliding plate 28 passes through the groove 27 and slides in contact with the sludge extraction port 26. A baffle 29 is connected to the upper surface of the sliding plate 28 away from the sludge extraction shell 24. A return spring 30 is connected between the baffle 29 and the sludge extraction shell 24. A first roller 31 is installed on the side of the sliding plate 28 near the baffle 29. A vertically arranged support plate 32 is connected to the end of the sliding plate 28 away from the baffle 29. A second roller 33 is connected to the lower end of the support plate 32.

[0064] When cleaning the water channel 1, the sludge suction pipe 8 is connected to the sludge suction structure, the negative pressure machine 10 is turned on, and the sludge suction shell 24 is placed into the water channel 1. When the moving base 2 moves, it drives the sludge suction pipe 8 to move. When the sludge suction pipe 8 moves, it drives the sludge suction shell 24 to move. Due to the silt accumulated in the water channel 1, it generates a squeezing force on the support plate 32. When the support plate 32 is squeezed, it drives the sliding plate 28 to slide in the sliding groove 5 and opens the sludge suction port 26. When the sludge suction port 26 is opened, the negative pressure machine 10 drives the sludge suction pipe 8 to suck up the silt and impurities in the water channel 1. At the same time, when the sliding plate 28 moves, it drives the return spring 30 to compress.

[0065] When there is more silt and impurities in the water channel 1, the resistance to the sludge suction structure increases as it moves, resulting in greater pressure on the support plate 32. This also causes the sliding plate 28 to move a greater distance. As the sliding plate 28 moves a greater distance, the suction port 26 opens wider, thereby improving the efficiency of cleaning silt and impurities in the water channel 1. Conversely, when the amount of silt and impurities is small, the pressure on the support plate 32 is smaller, resulting in a smaller suction size at the suction port 26.

[0066] Because the silt and impurities in the water channel 1 are unevenly distributed, the amount of silt on the left and right sides of the water channel 1 will be inconsistent during the cleaning process. When one set of suction pipes 8 is suctioning, there is less silt in one place, while there is more silt in the other set of suction pipes 8. For the suction shell 24 with less silt, the sliding plate 28 moves a shorter distance and the suction port 26 opens smaller. For the suction shell 24 with more silt, the suction port 26 opens larger. At this time, the suction force generated by the negative pressure machine 10 will act more on the suction pipe 8 with more silt, thereby increasing the suction force in the place with more silt. In this way, the suction force of different suction pipes 8 can be automatically adjusted according to the distribution of silt and impurities in the water channel 1.

[0067] The first roller 31 and the second roller 33 facilitate the movement of the sludge suction shell 24 within the water channel 1.

[0068] It should be noted that, due to the large mass of the silt, the support plate 32 can be squeezed by moving the base 2. When the silt and impurities are completely sucked out, the water in the channel 1 is insufficient to squeeze and move the support plate 32. Thus, the reset action of the reset spring 30 drives the slide plate 28 to slide and reset in the slide groove 5, thereby closing the corresponding sewage suction pipe 8.

[0069] To facilitate the drainage of silt and impurities, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a first one-way valve 34 provided at one end of the first drain pipe 17 near the first spiral shaft 13, and a second one-way valve 35 provided at one end of the second drain pipe 9 near the second spiral shaft 19.

[0070] In use, the first check valve 34 and the second check valve 35 prevent water from being discharged through the first drain pipe 17 and the second drain pipe 9. Only when the first spiral shaft 13 and the second spiral shaft 19 rotate, squeezing silt and other impurities into the first drain pipe 17 and the second drain pipe 9, can the first check valve 34 and the second check valve 35 be opened by the rotation of the first spiral shaft 13 and the second spiral shaft 19, and the silt and impurities be discharged.

[0071] To facilitate adjustment of the position of the sewage tank 7 on the truss 4, for example, as shown... Figure 1 , Figure 2 As shown, the present invention also includes a sliding sleeve 36 fitted on the upper end of each slider 3, and a telescopic rod 37 provided on the side of each sliding groove 5 near the slider 3, wherein the telescopic end of the telescopic rod 37 is connected to the sliding sleeve 36.

[0072] In use, by placing the mobile base 2 on both sides of the water channel 1 and adjusting the telescopic rod 37, the position of the sewage tank 7 on the truss 4 can be adjusted to correspond to the width of the water channel 1, thereby facilitating the cleaning of water channels 1 of different widths.

[0073] In order to move the mobile base 2, such as Figure 3 As shown, the present invention also includes a set of electric steering drive wheels 38 and a set of support wheels 39 on each side of the mobile base 2.

[0074] In use, the electric steering drive wheel 38 and support wheel 39 facilitate the movement of the mobile base 2 in coordination with the two sides of the water channel 1. By moving the mobile base 2, the silt in the water channel 1 can be pumped and cleaned while moving.

[0075] To improve the ease of cleaning canal 1, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes a water pump 40 provided on the side of the sewage tank 7 away from the sewage suction pipe 8, the water pump 40 being connected to the sewage tank 7, and a drain pipe 41 installed on one side of the water pump 40, the drain pipe 41 being connected to the water pump 40.

[0076] When in use, the water in the sewage tank 7 can be discharged through the drain pipe 41 by turning on the water pump 40, which improves the convenience of cleaning the water channel 1.

[0077] To improve the cleaning effect of canal 1, such as Figure 6 , Figure 7 , Figure 8 As shown, the present invention further includes a cavity 42 located on the side of the suction shell 24 near the spring, a double-threaded transmission rod 43 located within the cavity 42, both ends of the double-threaded transmission rod 43 being rotatably connected to the inner wall of the cavity 42, a transmission gear 46 connected to the middle of the double-threaded transmission rod 43, two sets of rotating shafts 47 rotatably connected to the side of the suction shell 24 near the spring, one end of each rotating shaft 47 passing through the suction shell 24 and placed inside the cavity 42, a driven gear 49 connected to the end of the rotating shaft 47 located inside the cavity 42, the two sets of driven gears 49 respectively meshing with the double-threaded transmission rod 43, a plug rod 44 connected to the end of the rotating shaft 47 away from the driven gear 49, a toothed structure 45 located on the side of the slide plate 28 near the cavity 42, a notch 48 corresponding to the toothed structure 45 located on the upper inner side of the slot 27, and the transmission gear 46 meshing with the toothed structure 45.

[0078] When in use, if there is a lot of silt in the water channel 1, in order to prevent the mobile base 2 from continuing to move before the sludge suction pipe 8 has finished suctioning the silt, when the slide plate 28 moves, the tooth structure 45 on one side of the slide plate 28 meshes with the transmission gear 46 to drive the double-threaded transmission rod 43 to rotate. When the double-threaded transmission rod 43 rotates, it drives the driven gear 49 to rotate, thereby driving the rotating shaft 47 to rotate, and thus driving the insertion rod 44 to rotate towards the bottom of the water channel 1. When the slide plate 28 moves to the limit, the insertion rod 44 abuts against the bottom of the water channel 1, and the insertion rod 44 can prevent the mobile base 2 from continuing to move.

[0079] After the silt is suctioned out, the return spring 30 drives the slide plate 28 to move back to its original position. When the slide plate 28 moves, the tooth structure 45 meshes with the transmission gear 46 to drive the double-threaded transmission rod 43 to move back to its original position. When the double-threaded transmission rod 43 moves back to its original position, it drives the insertion rod 44 to move back to its original position. At this time, the moving base 2 can continue to move to suction and clean the water channel 1.

[0080] In use, when cleaning the water channel 1 is required, the movable base 2 is placed on both sides of the water channel 1, and the telescopic rod 37 is adjusted. When the telescopic rod 37 moves, the position of the sewage tank 7 on the truss 4 can be adjusted to correspond to the width of the water channel 1. The number and position of the suction pipes 8 are adjusted according to the width of the water channel 1. When the suction pipes 8 are adjusted to the appropriate position, the suction pipes 8 and the suction shell 24 are placed in the water channel 1. By turning on the negative pressure machine 10, the negative pressure machine 10 is used to clean the water channel 1. A negative pressure is generated inside the suction pipe 8. When a negative pressure is generated inside the suction pipe 8, the suction pipe 8 is moved by the moving base 2. When the suction pipe 8 moves, the suction shell 24 is moved. Due to the silt accumulated in the water channel 1, the support plate 32 is squeezed. When the support plate 32 is squeezed, the sliding plate 28 is moved in the sliding groove 5 and the suction port 26 is opened. When the suction port 26 is opened, the suction pipe 8 is driven by the negative pressure machine 10 to suck up the silt and impurities in the water channel 1 and suck the sludge into the sewage tank 7.

[0081] When the sludge is pumped from the ditch 1 into the sewage tank 7 by the sludge suction pipe 8, larger impurities such as garbage in the sludge are filtered onto the filter screen 12, while smaller impurities such as water fall into the sewage tank 7 through the filter screen 12. By turning on the first motor 16, the first motor 16 drives the first pulley 18 to rotate. The first pulley 18 drives the first transmission belt 15 to rotate. When the first transmission belt 15 rotates, it drives the first transmission wheel 14 to rotate. The first transmission wheel 14 drives the first spiral shaft 13 to rotate. By sliding contact between the first spiral shaft 13 and the filter screen 12, the impurities filtered on the filter screen 12 are squeezed into the first drain pipe 17, and the garbage on the filter screen 12 is discharged through the first drain pipe 17, thereby cleaning the pumped sludge and impurities for the first time.

[0082] When smaller impurities fall into the sewage tank 7 through the filter screen 12, the impurities and sludge will settle at the bottom of the sewage tank 7. The second motor 22 is turned on, which drives the second pulley 23 to rotate. When the second pulley 23 rotates, it drives the second transmission belt 21 to rotate. The rotation of the second transmission belt 21 drives the second transmission wheel 20 to rotate. When the second transmission wheel 20 rotates, it drives the second spiral shaft 19 to rotate. When the second spiral shaft 19 rotates, it squeezes the sludge and impurities settled at the bottom of the sewage tank 7. When the sludge and impurities are squeezed to a certain position, they are discharged through the second drain pipe 9, thus performing a second cleaning of the sludge, etc. At the same time, by turning on the water pump 40, the water in the sewage tank 7 can be discharged through the drain pipe 41, improving the convenience of cleaning the water channel 1.

[0083] When there is more silt and impurities in the water channel 1, the resistance to the sludge suction structure increases as it moves, resulting in greater pressure on the support plate 32. This also causes the sliding plate 28 to move a greater distance. As the sliding plate 28 moves a greater distance, the suction port 26 opens wider, thereby improving the efficiency of cleaning silt and impurities in the water channel 1. Conversely, when the amount of silt and impurities is small, the pressure on the support plate 32 is smaller, resulting in a smaller suction size at the suction port 26.

[0084] Because the silt and impurities in the water channel 1 are unevenly distributed, the amount of silt on the left and right sides of the water channel 1 will be inconsistent during the cleaning process. When one set of suction pipes 8 is suctioning, there is less silt in one place, while there is more silt in the other set of suction pipes 8. For the suction shell 24 with less silt, the sliding plate 28 moves a shorter distance and the suction port 26 opens smaller. For the suction shell 24 with more silt, the suction port 26 opens larger. At this time, the suction force generated by the negative pressure machine 10 will act more on the suction pipe 8 with more silt, thereby increasing the suction force in the place with more silt. In this way, the suction force of different suction pipes 8 can be automatically adjusted according to the distribution of silt and impurities in the water channel 1.

[0085] When there is a lot of silt in the water channel 1, in order to prevent the mobile base 2 from continuing to move before the sludge suction pipe 8 has finished suctioning the silt, when the slide plate 28 moves, the tooth structure 45 on one side of the slide plate 28 meshes with the transmission gear 46 to drive the double-threaded transmission rod 43 to rotate. When the double-threaded transmission rod 43 rotates, it drives the driven gear 49 to rotate, thereby driving the rotating shaft 47 to rotate, and thus driving the insertion rod 44 to rotate towards the bottom of the water channel 1. When the slide plate 28 moves to the limit, the insertion rod 44 abuts against the bottom of the water channel 1, and the insertion rod 44 can prevent the mobile base 2 from continuing to move.

[0086] After the silt is suctioned out, the return spring 30 drives the slide plate 28 to move back to its original position. When the slide plate 28 moves, the tooth structure 45 meshes with the transmission gear 46 to drive the double-threaded transmission rod 43 to move back to its original position. When the double-threaded transmission rod 43 moves back to its original position, it drives the insertion rod 44 to move back to its original position. At this time, the moving base 2 can continue to move to suction and clean the water channel 1.
