Description

Technical Field

[0001] This invention belongs to the field of drainage system technology, specifically relating to a dredging device and dredging system. Background Technology

[0002] Drainage ditches are one of the basic infrastructures in a drainage system. When water flows into a drainage ditch, it carries debris such as slag, which leads to the formation of a silt layer at the bottom of the ditch. The silt layer directly affects the drainage efficiency of the ditch, and as the silt layer continues to thicken, it becomes extremely difficult to clean.

[0003] In related technologies, sludge pumps are used to pump and clean drainage ditches. However, the silt layer often settles and sticks together. If it is pumped directly, it will not only easily cause the sludge pump to become clogged and overloaded, but the silt layer is also difficult to clean. A large amount of silt will remain in the drainage ditch. The remaining silt easily attracts new debris, resulting in high maintenance frequency. Summary of the Invention

[0049] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] See Figures 1-7 As shown, the dredging device of this embodiment includes a first vehicle body 1, which travels in a drainage ditch. The first vehicle body 1 has a cavity 13, and one end of the cavity has an opening 14, which is located in front of the first vehicle body 1 in the direction of travel.

[0051] like Figures 1-3As shown, the first vehicle body 1 is provided with a shovel assembly 2, a dispersing assembly 3, a suction component 4, and a sweeping assembly 5. The shovel assembly 2 has a shovel body 21, one end of which is connected to the opening 14 of the vehicle body, and the other end of which abuts against the bottom surface of the drainage ditch. The shovel assembly 2 is used to shovel up the silt in the drainage ditch so that the shoveled silt enters the cavity of the first vehicle body 1 through the opening. The dispersing assembly 3 is located in the cavity and is used to break up the silt in the cavity. The suction component 4 is connected to the cavity and is connected to a pumping device to pump out the silt in the cavity. The sweeping assembly 5 is located on the outside of the first vehicle body 1 and is used to sweep the drainage ditch.

[0052] In other words, during the movement of the first vehicle body 1, the shovel body 21 located at the front of the first vehicle body 1 can scoop up the silt deposited at the bottom of the drainage ditch. The silt enters the cavity 13 through the shovel body 21 and the opening 14 at the front of the first vehicle body 1. The dispersing component 3 is located in the cavity. With the action of the dispersing component 3, the clumps of silt can be dispersed, thereby forming silt particles with smaller particle sizes that are easy to be pumped out. The suction component 4 is connected to the pumping equipment to pump out the dispersed silt in the cavity. After the silt is scooped up by the shovel body 21, it can continuously enter the cavity, avoiding the silt from being dispersed in the drainage ditch and spreading into the water flow of the drainage ditch, causing secondary sedimentation. The dispersed silt is easier to pump out, avoiding clogging of the suction component 4.

[0053] Even after cleaning the drainage ditch with the shovel body 21, some silt will still adhere to the bottom of the drainage ditch. If it is not cleaned, it is easy to attract debris and form a silt layer at the bottom of the drainage ditch in a short time. This results in a high frequency of cleaning and maintenance of the drainage ditch and makes it difficult to effectively clean the drainage ditch. Therefore, by setting up the cleaning component 5, the drainage ditch can be cleaned, so that the bottom of the drainage ditch is scrubbed and the cleaning effect of the drainage ditch is improved.

[0054] like Figure 4 As shown, in order to ensure that the shoveled silt can enter the cavity relatively intact and to prevent the silt from disintegrating before entering the cavity, which would cause the silt to scatter into the water flow of the drainage ditch and cause secondary sedimentation, in some embodiments, a conveying component is provided on the shovel assembly 2. The conveying component is provided on the shovel body 21 to convey the silt shoveled by the shovel body 21 to the cavity of the first vehicle body 1.

[0055] The conveying component can reduce the friction between the shovel body 21 and the silt, and convert the movement of the silt on the shovel body 21 from the relative sliding between the shovel body 21 and the silt into the main conveying and pushing of the conveying component, giving the silt an upward force and preventing the silt from disintegrating before entering the cavity of the first vehicle body 1.

[0056] Optionally, such as Figure 4 As shown, the conveying component includes a drive roller 22, a driven roller 23, a conveying motor 24, and a conveyor belt 25. The drive roller 22 and the driven roller 23 are pivotally connected to the shovel body 21 via bearings. The conveying motor 24 is mounted on the shovel body 21 and is connected to the drive roller 22 for transmission. The conveyor belt 25 is wound around the drive roller 22 and the driven roller 23. When the conveying motor 24 drives the drive roller 22 to rotate, the conveyor belt 25 will rotate on the drive roller 22 and the driven roller 23 to convey the sludge located on the shovel body 21 into the cavity of the first vehicle body 1.

[0057] Furthermore, such as Figure 4 As shown, in order to improve the lifting effect of the conveyor belt 25 on the silt, a scraper plate 26 can be set on the conveyor belt 25. The length extension direction of the scraper plate 26 is perpendicular to the travel direction of the conveyor belt 25, that is, the length extension direction of the scraper plate 26 is parallel to the width direction of the conveyor belt 25. Multiple scraper plates 26 are arranged at intervals along the length direction of the conveyor belt 25.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments, the dispersing component 3 includes a first rotating shaft 31, a first rod 32, and a first driving part 33. The first rotating shaft 31 is pivotally mounted on the first vehicle body 1. There are multiple first rods 32, which are spaced apart on the first rotating shaft 31. The first driving part 33 is mounted on the first vehicle body 1 and is connected to the first rotating shaft 31 to drive the first rods 32 to rotate with the first rotating shaft 31.

[0059] Specifically, the first drive unit 33 is a motor, which is mounted on the first vehicle body 1. The first drive unit 33 is connected to the first rotating shaft 31 via a coupling. While multiple first rods 32 are arranged circumferentially along the first rotating shaft 31, multiple first rods 32 are also arranged axially along the first rotating shaft 31. For example, multiple first rods 32 are arranged along a spiral line on the first rotating shaft 31. Or, for example, multiple first rods 32 are divided into multiple disintegration units, and multiple disintegration units are arranged at intervals along the axial direction of the first rotating shaft 31. Each disintegration unit includes multiple first rods 32, and the multiple first rods 32 in each disintegration unit are arranged at equal intervals along the circumferential direction of the first rotating shaft 31.

[0060] Optionally, disintegrating teeth are provided on at least a portion of the first rod 32. The disintegrating teeth are arranged at intervals along the axial direction of the first rod 32. The cross-sectional area of ​​the disintegrating teeth gradually decreases from the end closer to the first rod 32 to the end farther away from the first rod 32. For example, the disintegrating teeth are conical or pyramidal. The axial direction of the first rod 32 is orthogonal to the axial direction of the first rotating shaft 31, and the axial direction of the disintegrating teeth is parallel to the axial direction of the first rotating shaft 31.

[0061] Preferably, the first rotating shaft 31 is arranged vertically, the first rod 32 is arranged horizontally, and the shredding teeth are arranged vertically.

[0062] like Figure 2 , Figure 3 and Figure 5 As shown, in order to improve the integration of the equipment and reduce the manufacturing cost, the sweeping component 5 and the dispersing component 3 can share a set of power equipment. Therefore, in some embodiments, the first rotating shaft 31 is arranged vertically and extends to the lower side of the first vehicle body 1. In this case, the sweeping component 5 includes a sweeping part 53 provided at the bottom of the first rotating shaft 31, and the sweeping part 53 is in contact with the bottom surface of the drainage ditch.

[0063] When the first rotating shaft 31 is activated, it can not only drive the first rod 32 to move and disperse the silt in the cavity of the first vehicle body 1, but also drive the cleaning unit 53 to clean the drainage ditch.

[0064] Optionally, the cleaning part 53 can be a scraper, such as a rubber scraper. The cleaning part 53 can also be a brush, which can be steel wires arranged in a cluster. A support rod can be provided on the first rotating shaft 31 to fix the scraper or the brush.

[0065] Besides integrating the sweeping component 5 and the dispersing component 3 together in the above embodiments, the sweeping component 5 can also be set up separately to achieve separate motion control of the dispersing component 3 and the sweeping component 5. In some embodiments, the sweeping component 5 includes a second rotating shaft, a sweeping part 53, and a second driving part. The second rotating shaft is pivotally connected to the first vehicle body 1, the sweeping part 53 is disposed on the second rotating shaft, and the sweeping part 53 is in contact with the bottom surface of the drainage ditch. The second driving part is disposed on the first vehicle body 1 and is connected to the second rotating shaft to drive the sweeping part 53 to rotate with the second rotating shaft. Specifically, the second rotating shaft is pivotally disposed on the first vehicle body 1 through a bearing, the second driving part is a motor, and the second driving part is connected to the second rotating shaft through a coupling to drive the second rotating shaft to move. The sweeping part 53 can adopt the same structure as the sweeping part 53 in the above embodiments.

[0066] Optionally, such as Figure 5 and Figure 6 As shown, in order to improve the cleaning effect of the cleaning component 5, the cleaning component 5 also includes a second rod 51 and an elastic element 52. The second rod 51 is connected to the corresponding first rotating shaft 31 or second rotating shaft. The elastic element 52 is provided on the second rod 51 and is coaxially arranged with the second rod 51. The cleaning part 53 is provided on the second rod 51 and the elastic element 52. The support rod in the above embodiment is also the second rod 51 here.

[0067] The elastic element 52 can be a cylindrical spring, and the cleaning part 53 is a brush provided on the second rod 51 and the elastic element 52, with multiple clustered steel wires distributed on the second rod 51 and the elastic element 52. Alternatively, the cleaning part 53 can be a scraper provided on the second rod 51 and the elastic element 52, with the scraper being a rubber plate and having flexibility so that the scraper can deform with the elastic element 52.

[0068] Due to the presence of the elastic element 52, the total length of the first rod 32 and the elastic element 52 is slightly greater than half the width of the bottom of the drainage ditch. When the first rod 32 and the elastic element 52 rotate with the shaft, the elastic element 52 will deform to a certain extent, which can increase the force between the cleaning part 53 and the side wall of the drainage ditch, and improve the cleaning effect of the cleaning part 53 on the silt stuck in the drainage ditch. When the first shaft 31 or the second shaft rotates, multiple second rods 51 drive the scraper or wire to rotate, thereby cleaning the bottom of the drainage ditch, so as to ensure that the scraper or wire can clean the drainage ditch effectively.

[0069] In some embodiments, such as Figure 5 As shown, the dredging device also includes a second vehicle body 6, which travels above the drainage ditch. The suction component 4 includes a suction pipe 41, which is mounted on the second vehicle body 6. The upper end of the suction pipe 41 is connected to the pumping equipment, and the lower end of the suction pipe 41 extends into the cavity of the first vehicle body 1.

[0070] In other words, by arranging the second vehicle body 6 on the drainage ditch, the suction component 4 can be arranged on the second vehicle body 6, and the suction pipe 41 can form a buffer between the cavity of the first vehicle body 1 and the pumping equipment, so that the connection between the pumping equipment and the suction pipe 41 is located outside the drainage ditch, so as to facilitate the connection between the components.

[0071] Optionally, such as Figure 5 As shown, the dredging device also includes an adjustment component 7. The suction pipe 41 is arranged vertically and is vertically movable relative to the first vehicle body 1 and the second vehicle body 6. The adjustment component 7 is located between the second vehicle body 6 and the suction pipe 41 to adjust the vertical height of the suction pipe 41. The lower end of the suction pipe 41 and the opening are respectively located on opposite sides of the dispersing component 3 so that the silt entering the cavity through the opening is broken by the dispersing component 3 and discharged through the suction pipe 41.

[0072] In other words, the position of the suction tube 41 can be adjusted to change its vertical position, thereby adjusting the position of its lower end within the cavity to optimize the suction effect on the accumulated material within the cavity. Different positions of the lower end of the suction tube 41 within the cavity result in different suction effects on the accumulated material and also affect the dispersion effect of the material within the cavity. Specifically, when the lower end of the suction tube 41 is close to the lower side of the cavity, the pumping device exerts a relatively large suction force on the accumulated material, allowing for rapid suction and a short residence time within the cavity. Conversely, when the lower end of the suction tube 41 is close to the upper side of the cavity, the pumping device exerts a relatively weak suction force, resulting in a longer residence time of the material within the cavity, allowing the dispersion component 3 to fully disperse the material. Therefore, appropriately adjusting the position of the lower end of the suction tube 41 can effectively optimize both the suction effect of the pumping device and the dispersion effect of the accumulated material.

[0073] Optionally, a filter screen 42 can be installed at the lower end of the suction pipe 41 to prevent large-diameter sediment from entering the suction pipe 41 and avoid clogging of the pumping equipment.

[0074] Optionally, such as Figure 7 As shown, the adjustment component 7 includes a slide groove 71 vertically mounted on the second vehicle body 6 and a slider 72 mounted in the slide groove 71. The straw 41 is connected to the slider 72. A driver is provided on the second vehicle body 6 to drive the slider 72 to move in the slide groove 71. When the driver drives the slider 72 to move up and down in the slide groove 71, the straw 41 will move up and down with the slider 72 to adjust the position of the lower end of the straw 41 in the cavity.

[0075] The actuator can be any of the following: lead screw 73, electric actuator, pneumatic cylinder, or hydraulic cylinder. When using lead screw 73, such as... Figure 7 As shown, a handwheel 74 is provided at the upper end of the lead screw 73, and a threaded hole matching the lead screw 73 is provided in the middle of the slider 72. The slider 72 can slide up and down in the slide groove 71. A limiting member can be set to prevent the slider 72 from rotating in the circumferential direction, or the slide groove 71 can be set as a rectangular slide groove 71 and the slider 72 can be set as a rectangular slider 72 to prevent the slider 72 from rotating in the circumferential direction in the slide groove 71.

[0076] Optionally, such as Figure 1 As shown, pushers 61 are installed on the second vehicle body to facilitate the operation of the second vehicle body by the staff. Four pushers can be installed on the second vehicle body 6, so that multiple staff can work at the same time to push the second vehicle body or control the direction of travel of the second vehicle body.

[0077] Optionally, both the first and second vehicle bodies are equipped with a walking component, that is, both the first and second vehicle bodies are equipped with walking wheels and walking motors to achieve self-propelled movement. Since the first vehicle body travels in the drainage ditch, in order to prevent the walking wheels from slipping in the drainage ditch, anti-skid chains can be installed on the walking wheels of the first vehicle body, or the walking wheels of the first vehicle body can be made of iron wheels, which include a hub and multiple iron plates arranged in a circumferential interval on the hub.

[0078] In order for the silt cleaned by the cleaning component 5 to be pumped away by the pumping equipment, in some embodiments, such as Figure 5 As shown, the sweeping component 5 is installed on the underside of the bottom plate of the first vehicle body 1. The bottom plate of the first vehicle body 1 is provided with a through hole 12. The silt removed by the sweeping component 5 can enter the cavity through the through hole 12. Due to the suction force of the pumping equipment, the water in the drainage ditch will converge into the cavity. Since the cavity has an opening at the front and sealed plates at the rear and sides, the water can only enter the cavity through the opening at the front and the through hole 12 at the bottom, thereby bringing the silt scooped up by the shovel body 21 and the silt removed by the sweeping component 5 into the cavity.

[0079] Furthermore, such as Figure 5 As shown, in order to prevent water flow located behind the first vehicle body 1 from entering the cavity of the first vehicle body 1 through the through hole 12, a baffle 11 is installed on the first vehicle body 1. The baffle 11 is located on the rear side of the first vehicle body 1 in the direction of travel, and the baffle 11 abuts against the bottom of the drainage ditch. At this time, the silt cleaned by the cleaning assembly 5 will not spread to the rear of the first vehicle body 1, and water flow behind the first vehicle body 1 will also be prevented from entering the cavity of the first vehicle body 1 through the through hole 12.

[0080] The dredging system of this invention includes a dredging device, a pumping device, a filter press device, and a third vehicle as described in any of the above embodiments. The pumping device's suction port is connected to the dredging device, and the filter press device is connected to the pumping device's discharge port, so that the silt pumped from the dredging device is pumped to the filter press device by the pumping device. The filter press device is used to filter the silt. The third vehicle travels on one side of the drainage ditch, and both the pumping device and the filter press device are arranged on the third vehicle.

[0081] The pumping equipment uses a mud pump, and the filter press uses a filter press. The silt in the cavity of the first vehicle body 1 is pumped to the filter press by the pumping equipment. The filter press separates the silt into solid and liquid. After the silt is filtered, it forms a mud cake which is discharged for composting or reuse by other means. The wastewater generated after filtration can be discharged into the drainage ditch and discharged away. Furthermore, the wastewater generated by filtration is discharged to the front of the first vehicle body 1 to prevent suspended solids in the wastewater from settling into the drainage ditch.
