Description

Technical Field

[0001] This invention relates to the field of culvert cleaning technology, specifically to an adjustable culvert dredging device. Background Technology

[0002] As a key drainage and water passage structure in highway, railway, municipal and water conservancy projects, culverts are prone to sedimentation and compaction of mud, sand, gravel, dead branches, domestic waste and silt carried by water flow during long-term operation. This causes the water passage cross-section to shrink and the drainage capacity to decrease. In severe cases, it can lead to problems such as siltation, waterlogging and structural erosion, which directly affect the safety and service life of the project.

[0003] Chinese patent CN111101590A discloses a municipal underwater culvert cleaning device, including a guide cable, a cleaning mechanism, and a traction power mechanism. The traction power mechanism pulls and drags the end of the guide cable located outside the culvert. The cleaning mechanism is sleeved on the guide cable and moves along with the guide cable inside the culvert, adhering to the culvert wall. The cleaning part of the cleaning mechanism remains in contact with the inner wall of the culvert at all times. The guide wheel mechanism is fixedly installed at the corner of the culvert, and its movable part is engaged with the guide cable. However, this device still has the following problems during use:

[0004] The cleaning mechanism always keeps in close contact with the inner wall of the culvert. If there is a lot of silt left on the inner wall of the culvert, the cleaning mechanism will not be able to make complete contact with the silt on the inner wall of the culvert, thus reducing the cleaning quality. For thick layers and hardened silt left on the inner wall, repeated cleaning is not possible. The cleaning mechanism of this device can only clean the inner wall of the culvert when it moves in one direction. When it moves in the opposite direction, the cleaning mechanism will drag the silt back, further reducing the cleaning quality.

[0005] Based on this, the present invention designs an adjustable culvert dredging device to solve the above problems. Summary of the Invention

[0036] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The tracked vehicle control device moves along the inner wall of the culvert. During the movement, the CCD can monitor the silt residue on the inner wall of the culvert in real time, which makes it convenient for subsequent operators to control the tracked vehicle to clean the areas with thicker mud layers in the culvert multiple times, thus improving the cleaning quality of silt. At this time, the telescopic scraper assembly is in a horizontal state, reducing the space occupied by the device and making it convenient for the telescopic scraper assembly to be extended and retracted, thereby adapting to culverts of different sizes.

[0037] 2. The rotating component controls the telescopic scraper assembly to rotate upwards to a vertical position. The telescopic scraper assembly extends upwards until it contacts the inner top of the culvert. The tracked vehicle then continues to move along the inner wall of the culvert. During this movement, the rotating component continues to control the telescopic scraper assembly to rotate downwards along the inner wall of the culvert. During rotation, the telescopic scraper assembly scrapes away the silt remaining on the inner wall of the culvert. The silt then falls to the inner bottom of the culvert under its own gravity, thus moving all the silt distributed on the inner wall of the culvert to the bottom for centralized treatment. During rotation, the telescopic scraper assembly also extends synchronously, maintaining contact with the inner wall of the culvert, achieving comprehensive cleaning of the inner wall and preventing silt residue. The telescopic scraper assembly then resets to its original position to avoid hard friction between the telescopic scraper assembly and the inner wall of the culvert when the rotating component drives it to rotate upwards to reset, thereby extending the service life of the device.

[0038] 3. The tilting scraper assembly adheres closely to the inner wall of the culvert, reducing gaps between the assembly and the wall, preventing sludge residue, and improving sludge removal efficiency. As the tracked vehicle continues to move, the tilting scraper assembly gathers the sludge removed by the telescopic scraper assembly towards the center, facilitating subsequent sludge recovery by the following material collection mechanism. Subsequently, as the tracked vehicle continues to move, the following material collection mechanism recovers the sludge gathered at the bottom of the culvert by the tilting scraper assembly and discharges it outside the culvert. This not only prevents sludge residue from affecting the tracked vehicle's operation but also avoids the sludge buildup preventing the tilting scraper assembly from directly contacting the inner wall of the culvert, further improving the sludge removal effect. If a thick layer of sludge remains on the inner wall of the culvert, the tilting scraper assembly retracts inward and separates from the inner wall, thus preventing the sludge from flowing back when the tracked vehicle retracts.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0050] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0051] Example 1: In some embodiments, please refer to Figure 1- in the specification. Figure 7 An adjustable culvert dredging device includes a tracked vehicle 1, a CCD 2, an adjustable inner wall scraping mechanism 3, a material gathering and feeding mechanism 4, and a follow-up material receiving mechanism 5.

[0052] A CCD 2 for visual monitoring of the inner wall of the culvert is fixedly installed on the upper end of the tracked vehicle 1;

[0053] A controller (not shown in the figure) is also fixedly installed on tracked vehicle 1; the controller is connected to CCD 2 for communication.

[0054] An adjustable inner wall scraping mechanism 3 for cleaning the upper side of the inner wall of the culvert is installed at the upper middle part of the tracked vehicle 1.

[0055] The adjustable inner wall scraping mechanism 3 includes a horizontal support frame 31, a rotating assembly, and a telescopic scraping assembly; the horizontal support frame 31 is fixedly installed at the upper middle part of the tracked vehicle 1; the rotating assembly is connected to the horizontal support frame 31; and the telescopic scraping assembly is connected to the rotating assembly.

[0056] The material gathering and feeding mechanism 4, used to clean the lower side of the inner wall of the culvert and control the silt at the bottom of the culvert to gather towards the middle, is installed on the upper end of the tracked vehicle 1.

[0057] The material gathering and feeding mechanism 4 includes a synchronous drive component and a tilting and scraping component; the synchronous drive component is connected to the tracked vehicle 1; the tilting and scraping component is installed on the tracked vehicle 1 and connected to the synchronous drive component.

[0058] The follow-up material collection mechanism 5, used to discharge the silt from the culvert, is installed on the upper end of the tracked vehicle 1.

[0059] In this invention, the tracked vehicle 1 control device moves along the inner wall of the culvert. During the movement, the CCD 2 can monitor the silt residue on the inner wall of the culvert in real time, which makes it easier for subsequent operators to control the tracked vehicle 1 to clean the areas with thicker mud layers in the culvert and improve the quality of silt cleaning.

[0060] At this time, the telescopic scraper assembly is in a horizontal state, which reduces the space occupied by the device and facilitates the extension and retraction of the telescopic scraper assembly to adapt to culverts of different sizes.

[0061] Then the rotating component controls the telescopic scraper component to rotate upwards to a vertical position, and the telescopic scraper component extends upwards until it contacts the inner top of the culvert;

[0062] The tracked vehicle 1 then continues to move along the inner wall of the culvert. During the movement, the rotating component continues to control the telescopic scraper component to rotate downward along the inner wall of the culvert. During the rotation, the telescopic scraper component will scrape off the silt remaining on the inner wall of the culvert. At this time, the silt will fall to the bottom of the culvert under its own gravity, so that the silt distributed on the inner wall of the culvert will be moved to the bottom of the culvert and centrally processed. During the rotation, the telescopic scraper component will also extend synchronously to keep in contact with the inner wall of the culvert, so as to achieve all-round cleaning of the inner wall of the culvert and avoid silt residue.

[0063] The telescopic scraper assembly will then reset, preventing hard friction between the telescopic scraper assembly and the inner wall of the culvert when the rotating assembly drives the telescopic scraper assembly to rotate upwards and reset, thereby improving the service life of the device.

[0064] Furthermore, the tilting scraper assembly will fit tightly against the inner wall of the culvert, reducing the gap between the tilting scraper assembly and the inner wall of the culvert, avoiding sludge residue, and improving sludge cleaning efficiency; as the tracked vehicle 1 continues to move, the tilting scraper assembly will gather the sludge removed by the telescopic scraper assembly towards the center, making it convenient for the subsequent follow-up material collection mechanism 5 to recycle the sludge.

[0065] Then the tracked vehicle 1 continues to move, and the follow-up material collection mechanism 5 will collect the silt that has been gathered at the bottom of the culvert by the tilting scraper and discharge it to the outside of the culvert. This not only avoids the silt residue from affecting the operation of the tracked vehicle 1, but also avoids the silt accumulation from scraping, which would prevent the tilting scraper from directly contacting the inner wall of the culvert, thus further improving the cleaning effect of the silt.

[0066] If a thick layer of silt remains on the inner wall of the culvert, the flip-over scraper assembly will retract inward and separate from the inner wall of the culvert, thereby preventing the silt from flowing back when the tracked vehicle 1 reverses.

[0067] Example 2: In some embodiments, such as Figures 1-7As shown, in a preferred embodiment of the present invention, the rotating assembly includes a first drive motor 33, an L-shaped control plate 34, and a rotary cylinder 35; first clearance grooves 32 are symmetrically provided on the left side of the front and rear sides of the horizontal support frame 31; the first drive motor 33 is symmetrically and fixedly installed on the front and rear sides of the left end of the horizontal support frame 31; the L-shaped control plate 34 is rotatably connected to the inner wall of the left side of the first clearance groove 32; the output end of the first drive motor 33 is fixedly connected to the L-shaped control plate 34.

[0068] The left end of the horizontal support frame 31 is also fixedly equipped with a protective cover for protecting the first drive motor 33.

[0069] A rotary cylinder 35 is fixedly installed at one of the two L-shaped control plates 34 that are far apart from each other; the output end of the rotary cylinder 35 is connected to the telescopic scraper assembly; the L-shaped control plate 34 is connected to the telescopic scraper assembly.

[0070] The telescopic scraper assembly includes a fixed U-shaped plate 36, an extension push cylinder 37, a movable U-shaped plate 38, a vertical scraper 39, and a vertical guide rod 310; the fixed U-shaped plate 36 is symmetrically rotated and installed at one end of the two L-shaped control plates 34 that are close to each other; the output end of the rotary cylinder 35 is fixedly connected to the fixed U-shaped plate 36.

[0071] The extension push cylinder 37 is fixedly installed on the inner wall of the fixed U-shaped plate 36; the output end of the extension push cylinder 37 is fixedly connected to the lower end of the movable U-shaped plate 38; the vertical guide rod 310 is symmetrically fixedly installed on the left and right sides of the lower end of the movable U-shaped plate 38; the vertical guide rod 310 is limited and slidably connected to the fixed U-shaped plate 36; the vertical scraper 39 is fixedly installed on the upper end of the movable U-shaped plate 38.

[0072] The two vertical scrapers 39 at the front and back tend to tilt in opposite directions;

[0073] In this invention, the tracked vehicle 1 control device moves along the inner wall of the culvert. During the movement, the CCD 2 can monitor the silt residue on the inner wall of the culvert in real time, so that the subsequent operators can control the tracked vehicle 1 to clean the area with thick mud in the culvert.

[0074] At this time, the fixed U-shaped plate 36 and the movable U-shaped plate 38 are in a horizontal state, thereby reducing the space occupied by the device and facilitating the extension and retraction of the movable U-shaped plate 38 to adapt to culverts of different sizes.

[0075] Subsequently, the rotary cylinder 35 controls the fixed U-shaped plate 36 to rotate upward, causing the fixed U-shaped plate 36 to drive the movable U-shaped plate 38 to rotate into a vertical state. Then, the extended push cylinder 37 pushes the movable U-shaped plate 38 to move upward following the vertical guide rod 310 until the top of the movable U-shaped plate 38 contacts the inner top of the culvert. Then, the two front and rear first drive motors 33 respectively control the two front and rear L-shaped control plates 34 to rotate around the hinge point with the horizontal support frame 31 in a direction away from each other, so that the vertical scraper 39 cleans the inner top of the culvert and avoids cleaning residue.

[0076] Since the rotation centers of the two fixed U-shaped plates 36 are misaligned with the center of the culvert, the vertical scraper 39 will separate from the inner wall of the culvert during rotation. When the fixed U-shaped plate 36 rotates downward, the extension push cylinder 37 will also control the movable U-shaped plate 38 to continue to extend outward, so that the vertical scraper 39 can keep in contact with the inner wall of the culvert, thereby enabling the device to clean the silt remaining on the inner wall of the culvert more thoroughly.

[0077] If there is a lot of silt left on the inner wall of the culvert, the above operation can be repeated to clean the inner wall of the culvert multiple times.

[0078] After being scraped off, the silt will fall to the bottom of the culvert under its own gravity or move along the inner wall of the culvert to the bottom of the culvert. This allows the silt distributed on the inner wall of the culvert to be moved to the bottom of the culvert for centralized treatment, thus improving the efficiency of silt removal.

[0079] After the two vertical scrapers 39 have completed a full scraping operation on the inner wall of the culvert, the extended push cylinder 37 will control the movable U-shaped plate 38 to reset, so that the vertical scraper 39 is separated from the inner wall of the culvert. This avoids hard friction between the upper side of the vertical scraper 39 and the inner wall of the culvert when the L-shaped control plate 34 rotates upward to reset, thereby improving the service life of the vertical scraper 39.

[0080] When the tracked vehicle 1 moves along the inner wall of the culvert, the flipping scraper assembly will remove the silt on the lower side of the inner wall on both the front and rear sides of the culvert, and can also disperse the clumps of silt located on the left side of the tracked vehicle 1's moving direction, so as to avoid the excessive silt affecting the recycling efficiency of the follow-up material collection mechanism 5.

[0081] Furthermore, the synchronous drive component can also control the tilting scraper component to gather the silt located on the front and rear sides of the bottom of the culvert towards the middle, thereby preventing the silt from spreading and facilitating the subsequent follow-up material collection mechanism 5 to recycle the silt. As the tracked vehicle 1 continues to move, the follow-up material collection mechanism 5 will collect the silt gathered at the bottom of the culvert and discharge it to the outside of the culvert. This not only prevents the silt residue from affecting the operation of the tracked vehicle 1, but also prevents the tilting scraper component from being unable to directly contact the inner wall of the culvert due to the accumulation of silt during scraping, further improving the cleaning effect of the silt.

[0082] The synchronous drive assembly includes a drive ring 44 and a material pushing cylinder 45; the material pushing cylinder 45 is symmetrically fixedly installed on the front and rear sides of the upper end of the tracked vehicle 1; the drive ring 44 is fixedly connected to the output end of the material pushing cylinder 45; the drive ring 44 is connected to the tilting scraping assembly.

[0083] The overturning scraping assembly includes a fixed base 41, an L-shaped rotating plate 42, a driven roller 43, a reset torsion spring 46, a transverse scraper 47, and a limiting plate 48; the fixed base 41 is symmetrically fixedly installed on the front and rear sides of the upper end of the tracked vehicle 1; the middle part of the L-shaped rotating plate 42 is rotatably connected to the fixed base 41.

[0084] The driven roller 43 is symmetrically rotated and installed on the upper end of the front and rear L-shaped rotating plates 42, close to each other; and the driven roller 43 is in close sliding connection with the inner wall of the drive ring 44.

[0085] The transverse scraper 47 is symmetrically rotated and installed on the lower end of the front and rear L-shaped rotating plates 42 on opposite sides; and a reset torsion spring 46 is wound around the rotation shaft of the transverse scraper 47 and the L-shaped rotating plate 42. One end of the reset torsion spring 46 is fixedly connected to the rotation shaft of the transverse scraper 47 and the L-shaped rotating plate 42; the other end of the reset torsion spring 46 is fixedly connected to the transverse scraper 47.

[0086] By resetting the torsion spring 46, the two transverse scrapers 47 at the front and rear always tend to rotate in a direction away from each other.

[0087] The left ends of both front and rear transverse scrapers 47 are provided with chamfers to facilitate the removal of silt from the inner wall of the culvert.

[0088] The limiting plate 48, which is used to prevent the horizontal scraper 47 from rotating outward continuously, is symmetrically and fixedly installed on the side of the two L-shaped rotating plates 42 that are far apart from each other.

[0089] In this invention, the tracked vehicle 1 control device moves along the inner wall of the culvert. During the movement, the CCD 2 can monitor the silt residue on the inner wall of the culvert in real time, so that the subsequent operators can control the tracked vehicle 1 to clean the area with thick mud in the culvert.

[0090] Subsequently, the rotary cylinder 35 controls the fixed U-shaped plate 36 to rotate upward, causing the fixed U-shaped plate 36 to drive the movable U-shaped plate 38 to rotate into a vertical position. Then, the extension push cylinder 37 first pushes the movable U-shaped plate 38 to move upward following the vertical guide rod 310. Then, the first drive motor 33 controls the L-shaped control plate 34 to rotate downward. At this time, the fixed U-shaped plate 36 rotates downward, and the extension push cylinder 37 also controls the movable U-shaped plate 38 to continue to extend outward, so that the vertical scraper 39 can keep in contact with the inner wall of the culvert.

[0091] After being scraped off, the silt will fall to the bottom of the culvert under its own gravity or move along the inner wall of the culvert to the bottom of the culvert.

[0092] Furthermore, when the tracked vehicle 1 enters the culvert, the material pushing cylinder 45 will push the drive ring 44 to move to the left, thereby causing the drive ring 44 to push the driven roller 43 to drive the front and rear L-shaped rotating plates 42 to rotate around the hinge point with the fixed seat 41 in a direction away from each other. In addition, the transverse scraper 47 will also press against the inner wall of the culvert under the restoring force of the return torsion spring 46, thereby reducing the gap between the transverse scraper 47 and the inner wall of the culvert, thus avoiding sludge residue and improving sludge cleaning efficiency.

[0093] After the two vertical scrapers 39 have completed a complete scraping operation on the inner wall of the culvert and reset, the tracked vehicle 1 continues to move. The horizontal scraper 47 will then scoop up the silt in the inner wall of the culvert that has been scraped by the vertical scrapers 39, and cause the silt to move to the right along the chamfer on the left end of the horizontal scraper 47.

[0094] Furthermore, the material pushing cylinder 45 will also control the drive ring 44 to move to the right. At this time, the drive ring 44 will pull the driven roller 43 to drive the front and rear L-shaped rotating plates 42 to rotate in a closer direction, so that the front and rear transverse scrapers 47 will gather the silt at the bottom of the culvert towards the center. The limiting plate 48 will also limit the transverse scrapers 47, so as to prevent the silt from pushing the front and rear transverse scrapers 47 away in a distant direction during the rotation of the L-shaped rotating plates 42, thereby preventing the silt from spreading and facilitating the subsequent follow-up material collection mechanism 5 to collect the silt. As the tracked vehicle 1 continues to move, the follow-up material collection mechanism 5 will collect the silt gathered at the bottom of the culvert and discharge it to the outside of the culvert.

[0095] Example 3: In some embodiments, such as Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the follow-up material receiving mechanism 5 includes an adjusting cylinder 52, a collection box 53, a follow-up control box 54, a second drive motor 55, a synchronous transmission assembly 56, a receiving roller 57, a spiral blade 58, a receiving pump body 510, a feed pipe 511, and a discharge pipe 512; the left end of the tracked vehicle 1 is symmetrically provided with second clearance grooves 51 on both the front and rear sides; the collection box 53 is rotatably connected to the inner wall of the front and rear second clearance grooves 51;

[0096] The adjusting cylinder 52 is symmetrically rotated and installed on the front and rear sides of the upper end of the tracked vehicle 1; the output end of the adjusting cylinder 52 is hinged to the upper end of the collection box 53.

[0097] The front and rear ends of the receiving roller 57 are rotatably connected to the front and rear inner walls of the collecting box 53;

[0098] Synchronous drive assembly 56 is installed at the rear end of collection box 53; one end of synchronous drive assembly 56 is fixedly connected to receiving roller 57;

[0099] The follow-up control box 54 is fixedly installed at the rear end of the collection box 53; the synchronous transmission component 56 is located inside the follow-up control box 54 to avoid direct contact between the synchronous transmission component 56 and the silt, which would affect the transmission effect.

[0100] The second drive motor 55 is fixedly installed on the front right side of the follow-up control box 54; the output end of the second drive motor 55 is fixedly connected to the other end of the synchronous transmission assembly 56.

[0101] The output end of the second drive motor 55 is connected to the take-up roller 57 via the synchronous transmission component 56.

[0102] The spiral blade 58 is fixedly installed on the outer end of the receiving roller 57; the right end of the collecting box 53 is provided with a receiving port 59;

[0103] The receiving pump body 510 is fixedly installed at the lower end of the tracked vehicle 1; one end of the feed pipe 511 is fixedly connected to the receiving port 59; the other end of the feed pipe 511 is fixedly connected to the input end of the receiving pump body 510.

[0104] One end of the discharge pipe 512 is fixedly connected to the output end of the receiving pump body 510; the other end of the discharge pipe 512 leads to the outside of the culvert.

[0105] like Figure 7 As shown, the synchronous transmission assembly 56 can be a synchronous belt and synchronous pulley transmission assembly;

[0106] In this invention, when the tracked vehicle 1 enters the culvert, the front and rear adjusting cylinders 52 push the collection box 53 to rotate downward around the hinge point with the second clearance groove 51 until the collection box 53 contacts the bottom of the culvert.

[0107] After the two vertical scrapers 39 complete a scraping operation on the inner wall of the culvert and reset, the tracked vehicle 1 continues to move. The horizontal scraper 47 will then scoop up the silt that has been scraped off by the vertical scrapers 39 on the inner wall of the culvert, and make the silt move to the right along the chamfer on the left end of the horizontal scraper 47. In addition, the material pushing cylinder 45 will control the drive ring 44 to move to the right, so that the two L-shaped rotating plates 42 rotate in a direction closer to each other, and make the two horizontal scrapers 47 gather the silt at the bottom of the culvert towards the middle.

[0108] Subsequently, the second drive motor 55 controls the rotation of the receiving roller 57 through the synchronous transmission assembly 56, thereby causing the spiral blade 58 to disperse the silt accumulated at the bottom of the culvert and control the silt to move towards the receiving port 59. Then, the receiving pump body 510 will suck the silt from the receiving port 59 and discharge the silt along the feed pipe 511 and the discharge pipe 512 to the outside of the culvert for easy collection.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
