Description

Technical Field

[0001] This invention relates to the field of waterway silt removal technology, specifically a water conservancy project waterway silt removal vehicle. Background Technology

[0002] Artificial open channels are very common in water conveyance projects. After a long period of operation, silt will accumulate in the channels to varying degrees. Once the siltation is severe, the water conveyance capacity will be significantly reduced, and it will no longer be able to achieve its original design efficiency. To avoid this situation, it is necessary to dredge the open channels in a timely manner.

[0003] Traditional open channel dredging methods mainly include manual dredging, hydraulic flushing, and mechanical dredging. However, traditional manual dredging is inefficient, labor-intensive, and costly, making it difficult to deal with large-area siltation. Hydraulic flushing consumes a large amount of water resources and may lead to secondary siltation downstream, which also has a certain impact on the ecological environment. Mechanical dredging is limited in narrow channels with complex terrain and has high requirements for construction sites. In view of this, we designed a high-efficiency silt removal machine that can adapt to the terrain of artificial open channels to make up for the shortcomings of traditional open channel dredging methods. Summary of the Invention

[0004] The purpose of this invention is to provide a water conservancy project water channel silt removal vehicle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water conservancy project water channel silt cleaning vehicle, including a vehicle body, a compartment installed on the top of the vehicle body, a sand collection compartment opened inside the compartment, an axle hydraulic control mechanism provided on the surface of the vehicle body, a water channel silt cleaning mechanism provided on the surface of the vehicle body, and a silt discharge mechanism provided on the surface of the vehicle body.

[0006] The silt removal mechanism for water channels includes a first frame, which is installed inside the front end of a storage chamber. A first side baffle is fixedly connected to the top of the first frame. A first conveyor belt is installed inside the first frame, and a first triangular prism protrusion is fixedly connected to the surface of the first conveyor belt. First control motors are installed at the top and bottom of the right side surface of the first frame. A first rotating shaft is rotatably connected to the front end of the bottom of the inner end of the first frame, and a first rotating scraper is fixedly connected to the surface of the first rotating shaft. A second control motor is installed at the front end of the bottom of the right side of the first frame. A guide plate is fixedly connected to the rear end of the top of the inner end of the first frame. An auxiliary guide plate is fixedly connected to the left side. A mud and sand shovel plate is fixedly connected to the center of the bottom front of the first frame. Telescopic chambers are opened at both ends of the mud and sand shovel plate. Side mud and sand shovel plates are installed at the inner end of the telescopic chambers. Sealing sleeves are installed at both ends of the mud and sand shovel plates. Hinges are fixedly connected to both ends of the bottom front of the first frame. Side plates are fixedly connected to the top outer end of the side mud and sand shovel plates. Hinges are installed on the back of the side plates. A first control box is fixedly connected to the bottom of the first frame. A first hydraulic parallel controller is installed at the inner end of the first control box. A connecting conduit is installed on the back of the first hydraulic parallel controller. A second control box is fixedly connected to the bottom of the sludge shovel. A hydraulic controller is installed in the center of the second control box. A bottom connecting seat is fixedly connected to the outer bottom of the side sludge shovel. A hydraulic telescopic column is installed between the hydraulic controller and the bottom connecting seat. The side sludge shovel is driven to extend and retract within the telescopic chamber by the hydraulic telescopic column. The shoveling range can be adjusted according to the actual width of the canal, adapting to different specifications of artificial open channels. This solves the problems of fixed range and limited operation in narrow channels caused by traditional mechanical dredging. The overall sludge collection efficiency is high. The first rotating scraper, driven by the second control motor, can remove sediment from the bottom of the canal. The accumulated stubborn mud and sand are scraped up to the mud and sand shovel plate; the first triangular prism protrusion on the surface of the first conveyor belt can enhance the gripping force of the mud and sand, and prevent it from slipping during the conveying process. Then, it is accurately sent into the sand collection bin through the guide plate and auxiliary guide plate to improve the collection efficiency. The side plate is hinged to the hinge seat through the hinge connection seat, and the telescopic chamber is sealed with the sealing sleeve. This can not only ensure the structural stability of the side mud and sand shovel plate when it is extended and retracted, but also prevent the mud and sand from leaking out from the gaps, reducing secondary cleaning work. The mud and sand cleaning mechanism of the water channel can effectively improve the cleaning efficiency of the mud and sand, and the cleaning range is flexible and adjustable, with strong operational stability.

[0007] Preferably, the first conveyor belt is driven by a first control motor, and the first rotating shaft is fixedly connected to the left output end of the second control motor.

[0008] Preferably, the end of the guide plate away from the first frame extends into the sand collection bin, and the side plate is hinged to the hinge seat through a hinged connecting seat.

[0009] Preferably, the hydraulic controller is controlled by a first hydraulic parallel controller, and the side mud and sand shovel is driven by a hydraulic telescopic column.

[0010] Preferably, the axle hydraulic control mechanism includes a vehicle main control device, which is installed at the center of the bottom of the vehicle body. Connection ports are provided at both the left and right sides and the front and rear ends of the vehicle main control device. A telescopic axle is installed inside the connection port, and a wheel is installed at the outer end of the telescopic axle. The vehicle main control device can control the telescopic axle to extend and retract within the connection port, adjusting the wheel spacing, enabling the vehicle to travel stably along or inside narrow, uneven canals. This solves the problems of traditional machinery having high requirements for construction sites and limited operation in complex terrain canals. Furthermore, the wheels are easy to disassemble and replace, and the vehicle body can be adjusted using jacks as needed. After being lifted, the wheels are replaced. The hydraulic control system inside the vehicle's main control unit is connected to the first hydraulic parallel controller via connecting pipes. It can synchronously control the hydraulic components of the ditch silt cleaning mechanism, achieving coordinated axle adjustment and dredging operations, improving the overall continuity of operations. Through the parallel connection of the hydraulic control system, the telescopic axle and the hydraulic controller can work synchronously, achieving synchronous extension and retraction, thus adapting to various different operating environments. By precisely controlling the telescopic axle, the balance of the vehicle body when driving around the ditch can be ensured, avoiding vehicle tilting or overturning due to improper wheel spacing, reducing operational safety risks.

[0011] Preferably, the telescopic axle is connected to the vehicle's main control device, and the telescopic axle is controlled by the vehicle's main control device. The water channel silt cleaning mechanism includes a first hydraulic parallel controller and a connecting pipe. The end of the connecting pipe away from the first hydraulic parallel controller is connected to the front of the vehicle's main control device, and a hydraulic control system is installed inside the vehicle's main control device.

[0012] Preferably, the sediment discharge mechanism includes a first support frame installed at the front and rear ends of the left center of the silo body. A second support frame is installed at the front and rear ends of the left center of the top of the silo body. A second frame is installed inside the first and second support frames. A second side baffle is fixedly connected to the top of the second frame. A second conveyor belt is installed inside the second frame, and a second triangular prism protrusion is fixedly connected to the surface of the second conveyor belt. A third control motor is installed at the top and bottom of the back of the second frame. A second rotating shaft is rotatably connected to the bottom right side of the inner end of the second frame, and a second rotating scraper is fixedly connected to the surface of the second rotating shaft. A fourth control motor is installed at the bottom of the back of the second frame. A control cylinder is installed at the bottom center of the right side of the silo body. A pneumatic telescopic column is installed to the left of the control cylinder, and a mud-pushing plate is installed to the left of the pneumatic telescopic column. After the sediment is moved into the sediment collection silo by the water channel sediment cleaning mechanism, it can be discharged by the sediment discharge machine. The first mechanism discharges silt, and the control cylinder drives the pneumatic telescopic column to push the mud-pushing plate, which pushes the silt in the sand collection bin to the second conveyor belt. The second conveyor belt, driven by the third control motor, quickly transports the silt to the outside of the vehicle through the second triangular prism protrusion on its surface, eliminating the need for manual unloading and solving the problems of high labor intensity and low efficiency in traditional manual dredging. The second rotating scraper, driven by the fourth control motor, scrapes the silt remaining at the bottom of the sand collection bin to the second conveyor belt, preventing silt from accumulating and clogging inside the mechanism and ensuring the long-term stable operation of the discharge mechanism. The first and second support frames fix the second frame at different heights and positions, and together with the second side baffle, prevent the silt from falling from both sides during transportation. This ensures the structural stability of the second conveyor belt during operation and reduces silt waste and environmental pollution. The silt discharge mechanism enables rapid discharge of silt, thereby improving the overall cleaning efficiency of the canal.

[0013] Preferably, the second conveyor belt is controlled by a third control motor, the second rotating shaft is rotatably connected to the front output end of a fourth control motor, and the pneumatic telescopic column is controlled by a control cylinder.

[0015] Compared with the prior art, the present invention provides a silt removal vehicle for water conservancy engineering canals, which has the following beneficial effects:

[0016] 1. The water conservancy project's canal silt cleaning vehicle is equipped with a canal silt cleaning mechanism. Driven by a hydraulic telescopic column, the side silt shovels extend and retract within the telescopic chamber, allowing adjustment of the shoveling range according to the actual width of the canal. This adapts to different specifications of open canals, solving the problems of fixed dredging range and limited operation in narrow channels inherent in traditional mechanical dredging. The overall silt collection efficiency is high. Driven by a second control motor, the first rotating scraper scrapes up stubborn silt deposited at the bottom of the canal onto the silt shovels. The first triangular prism protrusion on the surface of the first conveyor belt enhances the gripping force on the silt, preventing slippage during transport. The silt is then precisely fed into the collection bin via guide plates and auxiliary guide plates, further improving collection efficiency. The side plates are hinged to each other via hinged connecting seats, and a sealing sleeve seals the telescopic chamber, ensuring structural stability during the extension and retraction of the side silt shovels and preventing silt leakage from gaps, reducing secondary cleaning work. The canal silt cleaning mechanism effectively improves silt cleaning efficiency, with a flexible and adjustable cleaning range and strong operational stability.

[0017] 2. The water conservancy project's canal silt removal vehicle is equipped with an axle hydraulic control mechanism. The vehicle's main control unit can control the extension and retraction of the telescopic axle within the connection port, adjusting the wheel spacing. This allows the vehicle to travel stably on or inside narrow, uneven canals, solving the problems of traditional machinery's high requirements for construction sites and limited operation in complex terrain. Furthermore, the wheels are easily disassembled and replaced; they can be replaced by jacking the vehicle body as needed. The hydraulic control system inside the vehicle's main control unit is connected to the first hydraulic parallel controller via connecting pipes, synchronously controlling the hydraulic components of the canal silt removal mechanism. This achieves coordinated axle adjustment and silt removal operations, improving overall operational continuity. The parallel operation of the hydraulic control system allows for synchronous work of the telescopic axle and hydraulic controller, enabling synchronized extension and retraction to adapt to various operating environments. Precise control of the telescopic axle ensures the vehicle's balance when traveling around the canal, preventing tilting or overturning due to improper wheel spacing and reducing operational safety risks.

[0018] 3. The water conservancy project's canal silt cleaning vehicle is equipped with a silt discharge mechanism. After the silt moves into the sand collection bin through the silt cleaning mechanism, it can be discharged through the silt discharge mechanism. The control cylinder drives the pneumatic telescopic column to push the mud-pushing plate, which can push the silt in the sand collection bin to the second conveyor belt. The second conveyor belt, driven by the third control motor, quickly transports the silt to the outside of the vehicle through the second triangular prism protrusion on its surface, eliminating the need for manual unloading and solving the problems of high labor intensity and low efficiency in traditional manual dredging. The second rotating scraper, driven by the fourth control motor, can scrape the silt remaining at the bottom of the sand collection bin to the second conveyor belt, preventing silt from accumulating and clogging inside the mechanism, and ensuring the long-term stable operation of the discharge mechanism. The first support frame and the second support frame fix the second frame at different heights and positions, and together with the second side baffle, prevent the silt from falling from both sides during transportation. This ensures the structural stability of the second conveyor belt during operation and reduces silt waste and environmental pollution. The silt discharge mechanism can achieve rapid discharge of silt, thereby improving the overall cleaning efficiency of the canal. Attached Figure Description

Once inside the sand collection bin 21, the sand can be discharged through the sand discharge mechanism 7. The control cylinder 702 drives the pneumatic telescopic column 703 to push the mud-pushing plate 704, which pushes the sand in the sand collection bin 21 towards the second conveyor belt 75. Driven by the third control motor 76, the second conveyor belt 75 quickly transports the sand to the outside of the vehicle body 1 through the second triangular prism protrusion 77 on its surface, eliminating the need for manual unloading and solving the problems of high labor intensity and low efficiency in traditional manual dredging.

[0044] The vehicle main control device 51 can control the telescopic axle 53 to extend and retract within the connection port 52, and adjust the spacing of the wheels 54, so that the vehicle body 1 can travel stably on or inside the narrow and uneven waterway edge, solving the problem of traditional machinery having high requirements for construction sites and limited operation in complex terrain channels. In addition, the wheels 54 are easy to disassemble and replace. As needed, the wheels 54 can be replaced after the vehicle body is lifted by the jack 4. The hydraulic control system inside the vehicle main control device 51 is connected to the first hydraulic parallel controller 6081 through the connecting pipe 6082, which can synchronously control the hydraulic components of the waterway silt cleaning mechanism 6, realize the coordination between axle adjustment and dredging operation, and improve the overall operation continuity. Through the parallel connection of the hydraulic control system, the telescopic axle 53 and the hydraulic controller 6091 can work synchronously to achieve synchronous extension and retraction, thereby adapting to a variety of different operating environments. By precisely controlling the telescopic axle 53, the balance of the vehicle body 1 when traveling around the waterway can be guaranteed, avoiding vehicle tilting or overturning due to improper wheel spacing, and reducing the risk of operation safety.

[0045] After the silt is moved into the sand collection bin 21 by the silt cleaning mechanism 6, it can be discharged by the silt discharge mechanism 7. The control cylinder 702 drives the pneumatic telescopic column 703 to push the mud pusher 704, which can push the silt in the sand collection bin 21 to the second conveyor belt 75. The second conveyor belt 75, driven by the third control motor 76, quickly transports the silt to the outside of the vehicle body 1 through the second triangular prism protrusion 77 on its surface. No manual unloading is required, which solves the problems of high labor intensity and low efficiency of traditional manual dredging. The second rotating scraper 79 is controlled by the fourth control motor 7. Driven by 01, the residual mud and sand at the bottom of the sand collection bin 21 can be scraped to the second conveyor belt 75, preventing the mud and sand from accumulating and clogging inside the mechanism, and ensuring the long-term stable operation of the discharge mechanism. The first support frame 71 and the second support frame 72 fix the second frame 73 from different heights and positions, and together with the second side baffle 74, prevent the mud and sand from falling from both sides during transportation. This not only ensures the structural stability of the second conveyor belt 75 during operation, but also reduces mud and sand waste and environmental pollution. The mud and sand discharge mechanism 7 can achieve rapid discharge of mud and sand, thereby improving the overall cleaning efficiency of the water channel.
