Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering dredging technology, specifically referring to a dredging and anti-siltation device for water conservancy projects. Background Technology

[0002] Water canals in water conservancy projects serve as core infrastructure for irrigation, drainage, and water conveyance. Their smooth flow directly affects the project's efficiency and safe operation. However, during long-term use, silt and gravel easily accumulate at the bottom of water canals, while sticky silt, moss, and various debris easily adhere to the side walls. If not cleaned in time, this can lead to a reduction in the flow cross-section, a decrease in water conveyance efficiency, and even disasters such as blockage and overflow. Therefore, dredging and anti-siltation equipment has become a key piece of equipment for the maintenance of water conservancy projects.

[0003] Currently, existing dredging equipment is mainly divided into two categories: manual dredging and mechanical dredging. Manual dredging is inefficient, labor-intensive, and poses safety hazards in complex environments such as deep water and narrow channels, making it difficult to meet the dredging needs of large-scale water conservancy projects. While mechanical dredging equipment has improved efficiency to some extent, it still has many technical shortcomings: 1. Traditional mechanical dredging equipment often adopts a dredging structure in one direction, such as a scraper design that only targets the bottom or a flushing structure that only targets the side walls. It cannot simultaneously dredge the bottom and side walls. The bottom silt is easy to leave residues at the edges after cleaning, and the sticky debris on the side walls is difficult to completely remove, resulting in the risk of local siltation in the water channel after dredging. 2. In equipment-based sludge removal and debris discharge are mostly independent processes. During the sludge removal process, the amount of sludge and debris accumulation needs to be monitored manually. When the sludge and debris reach a certain level, the machine is stopped and the debris is manually transferred. This not only interrupts the operation process but also increases the intervention cost for operators. Although some equipment is equipped with debris discharge mechanisms, the timed debris discharge mode is used, which is prone to problems such as empty discharge consuming energy or overflow and leakage of debris. The debris discharge efficiency is out of sync with the actual needs.

[0004] To address the aforementioned issues, there is an urgent need for a dredging and anti-siltation device with all-round dredging capabilities, adaptive debris removal function, and efficient power transmission characteristics, in order to improve dredging efficiency, reduce labor and energy costs, and adapt to diverse dredging scenarios in water conservancy projects. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a dredging and anti-siltation device for water conservancy projects, which effectively solves the problems currently on the market.

[0009] Furthermore, the drive mechanism also includes a bidirectional thread and a drive bevel gear; the bidirectional thread is located on the side of the rotating shaft near the wedge-shaped impurity removal block, and the bidirectional thread is threaded to the transmission connecting rod; the drive bevel gear is fixedly connected to the rotating shaft, and the drive bevel gear on the side near the wedge-shaped impurity removal block rotates in the opposite direction to the drive bevel gear on the side away from the wedge-shaped impurity removal block.

[0010] Furthermore, the automatic debris discharge assembly includes a support plate, a tilting plate, a fixed locking tooth, and a driven bevel gear; the support plate is fixedly connected to the other end of the reset spring and slidably connected in the lifting guide groove; the tilting plate is symmetrically arranged on the upper surface of the support plate, and one end of it is rotatably connected to the support plate; the fixed locking tooth is fixedly connected to the side of the tilting plate near the connecting housing and meshes with the fixed rack; the driven bevel gear and the driving bevel gear are corresponding in position and meshed.

[0011] Furthermore, the automatic debris discharge assembly also includes a push rod, a sliding bracket, a positioning shaft, and a rotating linkage assembly; the push rod is symmetrically fixed on the bearing plate; the sliding bracket is slidably connected to the bottom surface inside the housing, the positioning shaft passes through and is rotatably connected to the sliding bracket, and one end of the positioning shaft is fixedly connected to the driven bevel gear; the rotating linkage assembly includes a rotating linkage one and a rotating linkage two, one end of the rotating linkage one is fixedly connected to the sliding bracket, and the other end is rotatably connected to the rotating linkage two.

[0012] Furthermore, the automatic debris discharge assembly also includes a fixed bracket and a fixed rod; the fixed bracket is fixed to the upper surface of the sliding bracket, and one end of the fixed rod is fixedly connected to the fixed bracket; the gravity adaptive adjustment assembly includes a fixed sleeve, a lifting rod, and a fixed plate, the fixed sleeve is fixed to the bottom surface inside the connecting housing, the lifting rod is slidably connected to the fixed sleeve, and the fixed plate is symmetrically fixed to the lifting rod.

[0013] Furthermore, the gravity adaptive adjustment component also includes a sloping groove; the sloping groove is formed on the fixed plate, and the end of the fixed rod away from the fixed support is slidably connected to the sloping groove; it also includes a transmission rod and a wedge block, the transmission rod is fixedly connected to the sliding support and slidably connected to the outer shell, and the wedge block is fixed to the end of the transmission rod away from the sliding support and corresponds to the position of the push rod.

[0015] Furthermore, at least two sets of rotating plates are symmetrically arranged along the length of the bearing plate, and the fixing teeth are evenly distributed along the height of the rotating plate, with the tooth pitch of the fixing teeth matching the tooth pitch of the fixing rack.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: The dredging structure adopts a combination design of wedge-shaped debris removal blocks and symmetrical reciprocating cleaning blocks. The wedge-shaped debris removal blocks cut into the bottom silt layer with their pointed ends, and use the squeezing action of the wedge-shaped surface to push and collect the silt, reducing the dredging resistance at the bottom. The reciprocating cleaning blocks slide through a bidirectional threaded drive, and their outer walls fit tightly against the side walls of the canal, which can thoroughly scrape away sticky silt, moss, and debris from the wall crevices. The two work together to achieve all-round coverage of the bottom and side walls. The gravity-adaptive adjustment component triggers the impurity removal action based on the weight of the impurities themselves, eliminating the need for additional sensors, controllers, or other electronic components. When the weight of the impurities on the support plate reaches a preset threshold, the gravity of the impurities overcomes the support force of the reset spring and presses down on the lifting rod. Through the sliding cooperation between the inclined groove and the fixed rod, the sliding bracket is displaced, allowing the driven bevel gear and the driving bevel gear to precisely mesh and initiate impurity removal. The response time is short, and the timing of impurity removal perfectly matches the actual amount of impurities, avoiding the problems of empty removal and overflow in traditional timed impurity removal.

Therefore, they should not be construed as limitations on this invention.

[0022] like Figures 1-12 As shown.

[0023] In some embodiments, the debris storage assembly 2 may include a connecting housing 201 for storing debris cleaned during the dredging process; a lifting guide groove 202 symmetrically formed on the inner surface of the connecting housing 201; a return spring 203, one end of which is fixedly connected to the bottom surface inside the lifting guide groove 202; and a fixing rack 204 symmetrically arranged on the inner surface of the connecting housing 201, and the fixing rack 204 is fixedly connected to the return spring 203.

[0024] In some embodiments, the dredging structure 3 may include a wedge-shaped debris removal block 301, which is fixedly connected to the connecting shell 201 and is used to clean the silt and other debris at the bottom of the water channel; a reciprocating cleaning block 302, which is symmetrically arranged on the wedge-shaped debris removal block 301 and is slidably connected to the wedge-shaped debris removal block 301, and is used to clean the silt and other debris on both sides of the water channel; and a transmission link 303, which is fixedly connected to the reciprocating cleaning block 302 at one end and passes through and is slidably connected to the wedge-shaped debris removal block 301.

[0025] During the dredging operation, the connecting shell 201 drives the fixedly connected wedge-shaped debris removal block 301 to move along the axis of the water channel. The wedge-shaped debris removal block 301 adopts a wedge-shaped structure design, with its tip facing the direction of movement, which can easily cut into the silt layer at the bottom of the water channel. The squeezing action of the wedge-shaped surface pushes the silt and blocky debris deposited at the bottom forward, realizing the initial dredging and debris collection at the bottom of the water channel. During the sliding process, the outer wall of the reciprocating cleaning block 302 always adheres to the two side walls of the water channel, scraping away the sticky silt, moss, and debris hidden in the wall crevices attached to the side walls. At the same time, the bottom silt pushed by the wedge-shaped debris removal block 301 and the side wall debris scraped by the reciprocating cleaning block 302 converge in the middle of the water channel, forming a concentrated pile of silt and debris. As the dredging structure 3 continues to move, the concentrated pile of silt and debris is continuously transported forward.

[0026] In this embodiment, the wedge-shaped debris removal block and the reciprocating cleaning block form an all-round dredging coverage of the bottom and both sides. Compared with the traditional single-direction dredging structure, the cleaning range is increased to the entire area of ​​the water channel. The wedge-shaped structure of the wedge-shaped debris removal block reduces the dredging resistance at the bottom, and the symmetrical design of the reciprocating cleaning block ensures the synchronicity of the cleaning on both sides. The overall dredging efficiency is improved compared with traditional equipment, and it is especially suitable for water channels with regular cross sections such as rectangular and trapezoidal.

[0027] In some embodiments, the drive mechanism 4 may include a dual-output motor 401, symmetrically arranged on the bottom surface inside the connecting housing 201, and the dual-output motor 401 is fixedly connected to the connecting housing 201; a rotating shaft 402, fixedly connected to the output end of the dual-output motor 401; a bidirectional thread 403, arranged on the rotating shaft 402 near the wedge-shaped impurity removal block 301; and a drive bevel gear 404, fixedly connected to the rotating shaft 402.

[0028] The drive bevel gear 404 on the rotating shaft 402 near the wedge-shaped impurity removal block 301 is opposite to the drive bevel gear 404 on the rotating shaft 402 away from the wedge-shaped impurity removal block 301, and the transmission connecting rod 303 is threadedly connected to the bidirectional thread 403.

[0029] When the dredging operation begins, the dual-output motors 401, which are symmetrically arranged on the bottom surface inside the connecting shell 201, are activated. The dual-output motors 401 directly drive the rotating shaft 402, which is fixedly connected to its output end, to rotate synchronously. The symmetrical arrangement of the dual-output motors 401 on both sides enables synchronous start and stop and speed control, providing balanced power for subsequent coordinated dredging. The rotating shaft 402 near the wedge-shaped debris removal block 301 is provided with a bidirectional thread 403, and the transmission connecting rod 303 is threadedly connected to the bidirectional thread 403. When the rotating shaft 402 rotates, the bidirectional thread 403 converts the rotational motion into the linear reciprocating motion of the transmission connecting rod 303 through thread engagement, realizing the scraping and repositioning of debris on both sides of the canal.

[0030] In this embodiment, the bidirectional thread 403 drives the reciprocating cleaning block 302 to move back and forth through the transmission link 303, so that the device can scrape off the debris adhering to the side wall of the water channel and ensure the cleaning effect of the water channel.

[0031] In some embodiments, the automatic debris discharge assembly 5 may include a support plate 501, fixedly connected to the other end of the return spring 203, and slidably connected to the lifting guide groove 202; a flip plate 502, symmetrically arranged on the upper surface of the support plate 501, with one end of the flip plate 502 rotatably connected to the support plate 501; a fixing tooth 503, fixedly connected to the side of the flip plate 502 near the connecting housing 201; and a push rod 504, symmetrically arranged on the support plate 501, with the push rod 504 fixedly connected to the support plate 501. The sliding bracket 505 is slidably connected to the bottom surface inside the connecting housing 201; the positioning shaft 506 passes through and is rotatably connected to the sliding bracket 505; the first rotating link 507 is fixedly connected to the sliding bracket 505 at one end; the second rotating link 508 is rotatably connected to the end of the first rotating link 507 away from the sliding bracket 505 at one end; the fixed bracket 509 is fixedly installed on the upper surface of the sliding bracket 505; the fixed rod 510 is fixedly connected to the fixed bracket 509 at one end; and the driven bevel gear 511 is fixedly connected to one end of the positioning shaft 506.

[0032] The driven bevel gear 511 is positioned corresponding to the driving bevel gear 404, and the driven bevel gear 511 is engaged with the driving bevel gear 404, while the fixed snap ring 503 is engaged with the fixed rack 204.

[0033] In this dredging structure 3, the wedge-shaped debris removal block 301 and the reciprocating cleaning block 302 collect the debris from the bottom and side walls of the water channel and push it onto the support plate 501. The support plate 501 is elastically connected to the connecting housing 201 through the return spring 203 and slides along the lifting guide groove 202. In the initial state, the return spring 203 is in a natural extension and contraction state, and the support plate 501 maintains a horizontal receiving posture. When the support plate 501 rises, the fixing teeth 503 on the flip plate 502 will mesh with the fixing rack 204, and the flip plate 502 will rotate under the action of the fixing rack 204, so that the debris on the support plate 501 is pushed to both sides of the top of the water channel.

[0034] In some embodiments, the gravity adaptive adjustment component 6 may include a fixed sleeve 601, which is fixedly installed on the bottom surface inside the connecting housing 201; a lifting rod 602, which is slidably connected to the inside of the fixed sleeve 601; a fixed plate 603, which is symmetrically arranged on the lifting rod 602 and is fixedly connected to the lifting rod 602; and a slanted groove 604, which is formed on the fixed plate 603.

[0035] The end of the fixed rod 510 away from the fixed bracket 509 is slidably connected in the inclined groove 604.

[0036] As the number of debris on the bearing plate 501 increases, it will overcome the supporting force of the return spring 203 and move downward, squeezing the lifting rod 602. After being squeezed, the lifting rod 602 moves downward. As the lifting rod 602 moves downward, the inclined groove 604 opened on the fixed plate 603 pulls the sliding bracket 505 towards the direction of the dual output motor 401 through the fixed rod 510, until the driven bevel gear 511 and the driving bevel gear 404 mesh and connect together.

[0037] In this embodiment, the component is triggered by the weight of the sludge on the support plate 501. When the weight of the sludge reaches a preset threshold, the support plate 501 overcomes the supporting force of the return spring 203 and presses down the lifting rod 602. Through the sliding cooperation between the inclined groove 604 and the fixed rod 510, the sliding bracket 505 is displaced, so that the driven bevel gear 511 and the driving bevel gear 404 are precisely meshed to start the sludge removal. This avoids the problems of empty sludge removal energy consumption or overflow leakage caused by traditional timed sludge removal. The timing of sludge removal matches the actual amount of sludge. The triggering power of the component comes entirely from the gravity of the sludge itself. There is no need to add electronic components such as sensors and controllers or independent drive mechanisms 4. Adaptive adjustment is achieved through a purely mechanical structure.

[0038] The device also includes a drive trolley 1, a transmission rod 7, and a wedge block 8. The drive trolley 1 can push the connecting housing 201 to move by means of mechanical connection such as bolts. The transmission rod 7 is fixedly connected to the sliding bracket 505 and is slidably connected to the connecting housing 201. The wedge block 8 is fixedly connected to the end of the transmission rod 7 away from the sliding bracket 505, and the position of the wedge block 8 corresponds to the position of the push rod 504.

[0039] When the support plate 501 is raised to the designated position, the push rod 504 on the support plate 501 pushes the wedge block 8 to move, so that the wedge block 8 drives the sliding bracket 505 away from the dual-output motor 401 through the transmission rod 7, so that the fixed clevis 503 disengages from the drive bevel gear 404, and the support plate 501 returns to the initial position under the action of the return spring 203. At the same time, the sliding bracket 505 drives the lifting rod 602 to return to the initial position through the fixed rod 510.

[0040] Before dredging, the device is placed at the beginning of the ditch to be dredged. The drive trolley 1 is securely connected to the connecting housing 201 by bolts. The drive trolley 1 is started, and its power output drives the connecting housing 201 and the integrated components inside to move at a constant speed along the axial direction of the ditch. The moving speed can be flexibly adjusted according to the thickness of the silt, laying the foundation for subsequent stable dredging. In the initial state, the reset spring 203 is in a natural extension and contraction state, the lifting rod 602 of the gravity adaptive adjustment component 6 is in a high position under the reset support force, and the driven bevel gear 511 and the drive bevel gear 404 are in a separated state, ensuring that the positioning of each component is accurate before the device is started.

[0041] As the drive trolley 1 moves, the dual-output motor 401, which is symmetrically arranged on the bottom surface inside the connecting housing 201, is started synchronously. The output end of the motor drives the fixedly connected rotating shaft 402 to rotate synchronously. The two motors ensure balanced output power through synchronous start and stop and speed control. Two power transmission paths are formed on the rotating shaft 402: one path converts the rotational motion into linear reciprocating motion through the threaded engagement of the bidirectional thread 403 near the wedge-shaped impurity removal block 301 and the transmission connecting rod 303; the other path stores power for subsequent impurity removal actions through the drive bevel gear 404 at the end of the rotating shaft 402, forming a "one source, two drives" power distribution mode.

[0042] One end of the transmission connecting rod 303 is fixedly connected to the reciprocating cleaning block 302, and the other end is engaged with the bidirectional thread 403 of the rotating shaft 402. Its reciprocating motion directly drives the symmetrically arranged reciprocating cleaning block 302 to slide along the wedge-shaped debris removal block 301. At the same time, the connecting housing 201 drives the fixedly connected wedge-shaped debris removal block 301 to move synchronously. The wedge-shaped debris removal block 301, with its tip facing the direction of movement, easily cuts into the silt layer at the bottom of the canal. Through the squeezing action of the wedge-shaped surface, the bottom sediment and blocky debris are pushed forward, completing the initial dredging and collection of the bottom.

[0043] During the sliding process of the reciprocating cleaning block 302, the outer wall always adheres to the two side walls of the water channel, thoroughly scraping away the attached sticky silt, moss, and debris from the wall crevices. The bottom silt pushed by the wedge-shaped debris removal block 301 and the side wall silt scraped by the reciprocating cleaning block 302 converge in the middle of the water channel, forming a concentrated silt pile. As the device continues to move, it is steadily pushed onto the support plate 501 of the automatic debris discharge component 5, achieving silt removal without dead angles throughout the water channel.

[0044] As impurities accumulate on the support plate 501, their weight gradually increases and overcomes the supporting force of the return spring 203, causing the support plate 501 to move downward along the lifting guide groove 202. During the downward pressing process, the support plate 501 directly squeezes the lifting rod 602 of the gravity adaptive adjustment component 6, causing it to slide downward along the fixed sleeve 601, thereby driving the symmetrically fixed plate 603 to move downward synchronously. The inclined groove 604 on the fixed plate 603 is slidably connected to the fixed rod 510. The guiding effect of the inclined groove 604 pulls the sliding bracket 505 towards the direction of the dual-output motor 401 through the fixed rod 510, until the driven bevel gear 511 at the end of the positioning shaft 506 on the sliding bracket 505 precisely meshes with the driving bevel gear 404, completing the connection and switching of the impurity removal power.

[0045] After the driven bevel gear 511 meshes with the driving bevel gear 404, the rotational power is transmitted through the positioning shaft 506 to the rotating connecting rod 507 on the sliding bracket 505, causing the rotating connecting rod 507 to rotate around the positioning shaft 506. The end of the rotating connecting rod 507 away from the sliding bracket 505 is rotatably connected to the rotating connecting rod 508, converting the rotational motion into a push-pull action, pushing the bearing plate 501 to slide upward along the lifting guide groove 202 and stretching the return spring 203. During the upward movement of the bearing plate 501, the fixing teeth 503 of the flip plate 502 continuously mesh with the fixing rack 204, fixing... The tooth surface of the rack 204 guides the tilting plate 502 to tilt outward synchronously around the rotational connection point with the support plate 501. When the support plate 501 rises to the specified height, the tilting plates 502 on both sides form an inclined channel for removing debris. The debris on the plate slides down the top of the channel under the action of gravity, realizing the automatic discharge of debris. At the same time, the push rod 504 on the support plate 501 corresponds to the position of the wedge block 8 and generates compression, pushing the wedge block 8 to drive the sliding bracket 505 away from the dual-output motor 401 through the transmission rod 7, so that the driven bevel gear 511 disengages from the drive bevel gear 404.

[0046] After the power engagement is released, the bearing plate 501 slides down along the lifting guide groove 202 under the elastic potential energy of the return spring 203, returning to its initial horizontal posture. The flip plate 502 descends with the bearing plate 501, and the fixed clasp 503 engages with the fixed rack 204 again to return to the closed state. The reset of the sliding bracket 505 drives the lifting rod 602 to rise back to the initial position along the fixed sleeve 601 through the fixed rod 510. The gravity adaptive adjustment component 6 returns to the standby state. At this time, the drive trolley 1 continues to drive the device to move, entering the next round of "dredging-collection-discharge" cycle until the dredging of the entire water channel is completed. The above is the overall workflow of the present invention. This step can be repeated next time it is used. The actual operation process is very simple and easy.
