Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and particularly to an automatic dredging device for water conservancy projects. Background Art

[0002] To facilitate the management of water conservancy projects and water volume control, sluice gates are often set around reservoirs or in the middle of rivers to facilitate the control of the water volume in the channels, so as to play the role of storing water and preventing floods, and to facilitate the rational utilization of water resources. After the sluice gates are set up, the sluice gates will be in a closed state for a long time. The bottom and periphery of the water outlet will accumulate silt due to the daily water waves and the flow of water. At the same time, due to the long-term water storage state at the bottom of the river, there will also be a large amount of silt. When the sluice gate is opened, the silt at the bottom of the river will flow downstream along with the water flow, resulting in the blockage of the downstream river channel and the water outlet. Therefore, it is necessary to regularly carry out dredging work at the water outlet near the sluice gate.

[0003] At present, the dredging work of the silt in the river channel and the sluice gate is usually carried out by manual salvage. It is not only time-consuming and laborious, but also the dredging effect is not good. When using a boat to salvage silt, the salvaged silt can only be temporarily stored on the hull and needs to be transported repeatedly for many times. The efficiency is low and there is a risk of the salvage personnel falling into the water. For the current situation of large-area silt accumulation at the bottom of the river channel, using a sludge pump to suck silt over a large area has too large a project volume, and there are sundries such as glass bottles, metal blocks and wooden blocks in the silt, which are difficult to clean up centrally during the dredging process. Therefore, there is an urgent need for an automatic dredging device for water conservancy projects to solve the current problems. Summary of the Invention

A plurality of side plates are fixedly installed on the back of the fixed frame. A steering wheel is rotatably installed between two adjacent side plates. The other end of the towing rope is wound inside the steering wheel and fixedly connected to the top of the gate.

[0007] As a preferred technical solution of the present invention, a side groove is provided at the top of the side of the retaining platform away from the water outlet. A driving rod is rotatably installed inside the side groove between two adjacent storage platforms. A second driving motor is fixedly installed inside the storage platform and on the side of the retaining platform. The output end of the second driving motor passes through the storage platform and is fixedly connected to one side of the driving rod. The wire mesh barrier is fixedly installed on the side of the driving rod.

[0008] As a preferred technical solution of the present invention, a retaining rod is fixedly installed on the front of the dam and above the water outlet. A card slot is provided below the retaining rod. The side of the wire mesh barrier away from the driving rod is clamped inside the card slot.

[0009] As a preferred technical solution of the present invention, a plurality of push plates are fixedly sleeved at equal intervals on the outside of the telescopic end of the hydraulic telescopic rod. The push plates on the side where the telescopic ends of two adjacent hydraulic telescopic rods approach each other are in contact with each other.

[0010] As a preferred technical solution of the present invention, a plurality of uniformly distributed elastic steel bars are fixedly installed at the top of the push plate, and the top ends of the elastic steel bars are in contact with the wire mesh.

[0011] As a preferred technical solution of the present invention, through grooves symmetrically distributed are formed on the side surface of the push plate and on both sides of the hydraulic telescopic rod. Symmetrically distributed movable plates are rotatably installed inside the through grooves, and the movable plates can completely block the through grooves. A stop bar is fixedly installed on the side of the through groove on the side of the plurality of movable plates close to the fixed end of the hydraulic telescopic rod.

[0012] As a preferred technical solution of the present invention, symmetrically distributed support columns are fixedly installed on the top of the bottom platform and on the side far from the water outlet. The top of the support column is in contact with the bottom edge of the wire mesh. An inclined platform is fixedly installed on the side of the bottom platform and the storage bin far from the dam.

[0013] As a preferred technical solution of the present invention, a sludge pump is arranged on the top of the dam. A mud inlet pipe is installed on the front of the sludge pump, and a mud outlet pipe is installed on the side of the sludge pump. One end of a sludge suction pipe is fixedly installed on the side of the mud inlet pipe, and the other end of the sludge suction pipe extends to the inner bottom of the storage bin.

[0014] Compared with the prior art, the present invention provides an automatic dredging device for water conservancy projects, which has the following beneficial effects: 1. For the automatic dredging device for water conservancy projects, by controlling and starting the second drive motor through the controller to drive the drive rod to rotate, the wire mesh can be rotated to a vertical state and blocked outside the water outlet to block and filter the sundries in the river water flow. The second drive motor is a forward and reverse motor. When rotating in the reverse direction, it can drive the wire mesh to rotate to a horizontal state, push the sundries on the surface of the wire mesh above the bottom platform, and then be pushed into the storage bin by the push plate for centralized cleaning. This not only reduces the workload of sludge cleaning, but also does not affect the normal opening of the gate, reduces the manual workload, and improves the timeliness and efficiency of river dredging.

[0015] 2. For the automatic dredging device for water conservancy projects, by regularly controlling the hydraulic telescopic rod to contract through the controller, driving the push plate to move between the bottom platform and the wire mesh, pushing the accumulated sludge and solid sundries on the bottom platform into the storage bin from the bottom groove. When the hydraulic telescopic rod is completely contracted, the push plate will block the bottom groove. At this time, the staff can centrally clean the sludge and sundries in the storage bin. After the sludge in the bottom platform is cleaned, the other sludge in the river will continuously move above the bottom platform. Repeating this way can achieve the effect of centrally cleaning the sludge and sundries near the water outlet. Regular cleaning in this way can avoid the accumulation of sludge near the water outlet from blocking the water outlet.

[0016] 3. The automated dredging equipment for water conservancy projects drives the steel wire retaining net to rotate to a horizontal state. At this time, when the push plate reciprocates, it drives the elastic steel bars to contact the surface of the steel wire retaining net, cleaning the sundries adsorbed on the surface of the steel wire retaining net and dropping them above the bottom platform. This not only realizes the centralized cleaning of sundries but also dredges the mesh holes on the surface of the steel wire retaining net, enabling the water to flow smoothly after the steel wire retaining net rotates to a vertical state, further improving the thoroughness of cleaning the silt and sundries in the river channel.

[0017] 4. The automated dredging equipment for water conservancy projects, through the design of the retaining bars and the movable plate, enables the silt and other sundries to pass through the push plate from the through groove. In this way, the silt and other sundries can be retained above the bottom platform, so that during the reciprocating movement of the hydraulic telescopic rod, the silt and sundries at the bottom of the river can be smoothly pushed into the storage bin for centralized cleaning.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figures 1-8 , in this implementation scheme: An automatic dredging device for a water conservancy project includes a device main body arranged on a dam 1. The front of the dam 1 is provided with water outlet ports 102 distributed at equal intervals. The top of the dam 1 is provided with a receiving groove 101 communicating with the water outlet ports 102. A gate 8 is slidably inserted and installed inside the receiving groove 101. A bottom platform 3 is fixedly installed at the bottom of the front of the dam 1. A retaining platform 4 is fixedly installed on the top of the bottom platform 3 and on the side close to the front of the dam 1. The top of the retaining platform 4 is flush with the bottom of the water outlet port 102. A wire mesh retaining net 7 is rotatably installed on the side of the retaining platform 4. A storage platform 5 is fixedly installed on the front of the dam 1 and between two adjacent water outlet ports 102. The bottom platform 3 is located between two adjacent storage platforms 5. A storage bin 501 is opened inside the storage platform 5. Bottom grooves 503 communicating with the storage bin 501 are respectively opened at the bottoms on both sides of the storage platform 5. The fixed ends of symmetrically distributed hydraulic telescopic rods 502 are fixedly installed at the bottom inside the storage bin 501. The telescopic ends of the hydraulic telescopic rods 502 penetrate through the bottom grooves 503 and extend above the bottom platform 3. A push plate 504 is fixedly sleeved on the outside of the telescopic ends of the hydraulic telescopic rods 502. The size of the push plate 504 matches the size of the bottom grooves 503; When the gate 8 is in the closed state, the silt and sundries in the river channel will continuously accumulate at the bottom of the river channel. Driven by the water surface wind and waves, part of the silt at the bottom of the river will accumulate above the bottom platform 3. At this time, the wire mesh retaining net 7 is in a horizontal state. A controller is installed above the dam 1. The hydraulic telescopic rods 502 are periodically controlled by the controller to contract, driving the push plate 504 to move between the bottom platform 3 and the wire mesh retaining net 7, and pushing the silt and solid sundries accumulated on the bottom platform 3 into the storage bin 501 through the bottom grooves 503. When the hydraulic telescopic rods 502 are fully contracted, the push plate 504 will block the bottom grooves 503. At this time, the staff can centrally clean the silt and sundries in the storage bin 501. After the silt in the bottom platform 3 is cleaned, the other silt in the river channel will continuously move above the bottom platform 3. Repeating this process can achieve the effect of centrally cleaning the silt and sundries near the water outlet ports 102. Regular cleaning in this way can prevent the silt accumulation near the water outlet ports 102 from blocking the water outlet ports 102.

[0022] When the gate 8 is in the open state, the silt at the bottom of the river channel will move with the water flow to above the bottom platform 3. Under the reciprocating motion of the hydraulic telescopic rod 502, the silt can be continuously pushed into the storage bin 501. At the same time, the wire retaining net 7 is driven to rotate to the vertical state, so as to filter the water flow passing through the water outlet 102 and block the sundries in the river channel. The staff observes the water outlet state of the water outlet 102. If the water output decreases, the gate 8 is closed, and the wire retaining net 7 is driven to rotate to the horizontal state, so that the sundries accumulated on the surface of the wire retaining net 7 fall onto the bottom platform 3. The contraction of the hydraulic telescopic rod 502 can drive the push plate 504 to push the sundries into the storage bin 501 for centralized cleaning. In this way, whether the gate 8 is in the closed state or the open state, the silt at the bottom of the river channel can be cleaned, so that the river bottom silt is centrally treated, which not only reduces the workload of silt cleaning, but also does not affect the normal opening of the gate 8, reduces the manual workload, and improves the timeliness and efficiency of river channel dredging and silt cleaning.

[0023] As a preferred implementation manner, a lifting assembly 2 is fixedly installed on the top of the dam 1. The lifting assembly 2 includes a fixing frame 201 fixedly installed on the top of the dam 1. Symmetrically distributed fixing seats 207 are fixedly installed on the top of the fixing frame 201. A winding roller 202 is rotatably installed between the two fixing seats 207. One end of a towing rope 206 is wound around the outer side of the winding roller 202. A first driving motor 205 is fixedly installed on the side surface of the fixing seat 207. The output end of the first driving motor 205 penetrates through the fixing seat 207 and is fixedly connected to the port of the winding roller 202. A plurality of side plates 203 are fixedly installed on the back surface of the fixing frame 201. A turning wheel 204 is rotatably installed between two adjacent side plates 203. The other end of the towing rope 206 is wound around the inner side of the turning wheel 204 and then fixedly connected to the top of the gate 8. By controlling and starting the first driving motor 205 through the controller to drive the winding roller 202 to rotate, the towing rope 206 is wound around the winding roller 202 through the turning wheel 204, and the towing rope 206 pulls the gate 8 to move upward in the receiving groove 101 to open the water outlet 102. The first driving motor 205 is a forward and reverse rotation motor. When rotating in the reverse direction, the towing rope 206 can be loosened to make the gate 8 move downward to close the water outlet 102.

[0024] As a preferred embodiment, a side groove 401 is provided on the top of the side of the baffle 4 away from the water outlet 102, a driving rod 402 is rotatably installed between two adjacent storage platforms 5 and located inside the side groove 401, a second driving motor is fixedly installed inside the storage platform 5 and located on the side of the baffle 4, the output end of the second driving motor passes through the storage platform 5 and is fixedly connected to one side of the driving rod 402, and the wire baffle 7 is fixedly installed on the side of the driving rod 402. The second driving motor is controlled and started by the controller to drive the driving rod 402 to rotate, so that the wire baffle 7 can be rotated to a vertical state, blocking the outside of the water outlet 102, and blocking and filtering the debris in the river water flow. The second driving motor is a forward and reverse motor. When rotating in the reverse direction, it can drive the wire baffle 7 to rotate to a horizontal state, push the debris on the surface of the wire baffle 7 to the top of the bottom platform 3, and then push it to the storage bin 501 by the push plate 504 for centralized cleaning.

[0025] Example 2: Please refer to Figures 1-8 In this embodiment: a blocking rod 103 is fixedly installed on the front side of the dam 1 and above the water outlet 102, and a slot 104 is opened below the blocking rod 103. The side of the wire mesh 7 away from the driving rod 402 is clamped in the inner side of the slot 104, so that when the gate 8 is opened, the top of the wire mesh 7 is clamped in the slot 104. With the impact force of the water flow, the wire mesh 7 can always be in a vertical state, ensuring that the wire mesh 7 effectively filters debris in the water flow.

[0026] As a preferred embodiment, a plurality of push plates 504 are fixedly mounted on the outer side of the telescopic end of the hydraulic telescopic rod 502 and are evenly spaced, and the push plates 504 on the side where the telescopic ends of two adjacent hydraulic telescopic rods 502 are close to each other abut against each other; such a design allows the sludge accumulated on the base 3 to be pushed into the storage bin 501 in sections by the push plates 504, thereby avoiding the problem of too much sludge being unable to completely enter the storage bin 501 when a single push plate 504 is pushing, so that the sludge and debris can be pushed into the storage bin 501 in an orderly and thorough manner by the push plates 504.

[0027] As a preferred embodiment, a plurality of evenly distributed elastic steel bars 508 are fixedly installed on the top of the push plate 504, and the top of the elastic steel bar 508 is in contact with the wire mesh 7. When the gate 8 is in the open state, after a lot of debris is accumulated on the surface of the wire mesh 7, the wire mesh 7 is driven to rotate to a horizontal state. At this time, when the push plate 504 reciprocates, it drives the elastic steel bar 508 to contact the surface of the wire mesh 7, and the debris adsorbed on the surface of the wire mesh 7 is cleaned and dropped to the top of the base 3, which not only realizes the centralized cleaning of the debris, but also can dredge the mesh holes on the surface of the wire mesh 7, so that after the wire mesh 7 is rotated to a vertical state, the water flow can flow smoothly, further improving the thoroughness of cleaning the silt and debris in the river channel.

[0028] Embodiment 3: Please refer to Figures 1-8 , in this implementation plan: on the side of the push plate 504 and on both sides of the hydraulic telescopic rod 502, symmetrically distributed through grooves 505 are provided. Inside the through grooves 505, symmetrically distributed movable plates 506 are rotatably installed. The movable plates 506 can completely block the through grooves 505. On the side of the plurality of movable plates 506 close to the fixed end of the hydraulic telescopic rod 502 and on the side of the through groove 505, a stop bar 507 is fixedly installed; with such a design, when the hydraulic telescopic rod 502 contracts, under the blocking of the stop bar 507, due to inertia and the extrusion of the silt on the movable plates 506, the movable plates 506 can be in a closed state, and sundries such as silt can be pushed into the storage bin 501. When the hydraulic telescopic rod 502 extends, due to inertia and the extrusion of sundries such as silt on the movable plates 506, in the absence of the blocking of the stop bar 507, the movable plates 506 will rotate and open, and sundries such as silt will pass through the through grooves 505 and pass through the push plate 504. In this way, sundries such as silt can be retained above the bottom platform 3, so that during the reciprocating movement of the hydraulic telescopic rod 502, the silt and sundries at the bottom of the river can be smoothly pushed into the storage bin 501 for centralized cleaning.

[0029] As a preferred implementation method, symmetrically distributed support columns 301 are fixedly installed on the top of the bottom platform 3 and on the side far from the water outlet 102. The top of the support columns 301 abuts against the bottom edge of the wire mesh 7. Through the design of the support columns 301, the wire mesh 7 in a horizontal state can be supported. On the side of the bottom platform 3 and the storage bin 501 far from the dam 1, an inclined platform 6 is fixedly installed. The inclined platform 6, the storage platform 5, and the bottom platform 3 are all formed by concrete pouring at the beginning of the construction of the dam 1. The design of the inclined platform 6 can reinforce the stability of the bottom platform 3, and at the same time enable the silt at the bottom of the river to flow smoothly onto the bottom platform 3, facilitating the cleaning of sundries such as silt.

[0030] As a preferred implementation method, a sludge pump 9 is provided on the top of the dam 1. The front of the sludge pump 9 is equipped with a mud inlet pipe 901, and the side of the sludge pump 9 is equipped with a mud outlet pipe 902. One end of a sludge suction pipe 10 is fixedly installed on the side of the mud inlet pipe 901, and the other end of the sludge suction pipe 10 extends to the inner bottom of the storage bin 501. The sludge pump 9 and the sludge suction pipe 10 are used to suck the sludge entering the storage bin 501. At the same time, during the dredging process, the water in the river channel will enter the storage bin 501 through the bottom groove 503. When the sludge is pushed into the storage bin 501, the sludge will be mixed and diluted with the water in the storage bin 501, facilitating the suction of the sludge by the sludge suction pipe 10. At the same time, for solid sundries such as glass bottles, metal blocks, and wooden blocks entering the storage bin 501, the staff can use corresponding fishing tools for centralized fishing and cleaning.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
