Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy dredging devices, specifically a dredging device for water conservancy construction. Background Technology

[0002] Dredging devices for water conservancy construction refer to specialized equipment or systems used in water conservancy projects (such as rivers, lakes, reservoirs, canals, etc.) to remove silt, mud, and debris deposited at the bottom or slope of water bodies in order to restore the functions of water conservancy facilities such as flood control, irrigation, water supply, and navigation.

[0003] Patent CN220433781U discloses a dredging device for water conservancy projects, belonging to the technical field of dredging equipment. This utility model first starts the drive motor through the control terminal, which in turn starts the sludge pump to perform suction work. The suction plate and suction pipe are placed in the river channel to be dredged. The suction plate begins to suck the sludge into the suction pipe. The suction plate is equipped with a filter screen, which can effectively prevent large stone particles from being sucked into the sludge pump and causing damage to the machine. When the sludge enters the sludge collection box through the sludge pump, the control terminal starts to operate the extrusion plate connecting rod to slide downward through the extrusion plate connecting rod slide rail. The extrusion plate connecting rod pushes the extrusion plate downward to squeeze the sludge. After the sludge is squeezed, the water inside the sludge will be discharged from the drainage pipe below. Then, the unloading plate at the bottom of the sludge collection box is pulled out, and the squeezed sludge will fall from the bottom of the sludge collection box into the loading vehicle.

[0004] However, the aforementioned and existing sludge removal devices cannot simultaneously clean the filter plates during the sludge pressing and filtration process. This results in an accumulation of residual sludge over long-term use, affecting the subsequent filtration effect and damaging the core components of the device.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6In this embodiment of the utility model, a dredging device for water conservancy construction includes a dredging robot 1. A filter press box 4 is provided on one side of the dredging robot 1. A filter plate 15 is fixedly connected to the inner wall of the filter press box 4. The fixed connection position of the filter plate 15 is inclined downward. A transmission component is provided inside the filter press box 4 for transmitting and removing residual silt on the filter plate 15. The transmission component includes an electric push rod 7 installed on the top of the filter press box 4. The pressure plate 14 is fixedly connected to the output end of the electric push rod 7, and the fixed connection position of the pressure plate 14 is parallel to the fixed connection position of the filter plate 15. A first telescopic rod 12 is rotatably connected to one side of the bottom of the pressure plate 14. A spring is installed at the rotatable connection of the first telescopic rod 12. The end of the spring is fixedly connected to the bottom of the pressure plate 14. A first spring is installed inside the first telescopic rod 12. The initial position of the first telescopic rod 12 is a non-vertical position. A sliding groove 24 is provided at one end of the inner wall of the filter press 4. A slider 25 is slidably connected inside the sliding groove 24. A sealing telescopic pad is provided at the connection position between the slider 25 and the sliding groove 24. The other end of the first telescopic rod 12 is rotatably connected to the top of the slider 25. The scraper 26 is fixedly connected to the bottom of the slider 25, and the scraper 26 is in contact with the filter plate 15.

[0019] In this embodiment: Initially, the slider 25 is located at the lower end of the sliding groove 24. When a certain amount of sludge is transferred to the filter press box 4, the electric push rod 7 is activated to extend, causing the pressure plate 14 at its output end to move downward. That is, the pressure plate 14 filters the sludge to separate the mud and water. During this process, the first telescopic rod 12 will retract. After the filtration is completed, the electric push rod 7 is activated to retract, and the pressure plate 14 moves upward synchronously. Since the first telescopic rod 12 has a first spring installed inside, when the pressure plate 14 moves upward, it will cooperate with the first spring to prioritize the reset of the first telescopic rod 12. Continuing to activate the electric push rod 7 to retract, the pressure plate 14 will drive the first telescopic rod 12 to move, thereby driving the slider 25 at the bottom of the first telescopic rod 12 to move in the sliding groove 24, and at the same time causing the slider 25 to move. The scraper 26 at the bottom scrapes the filter plate 15, thereby scraping off the residual sludge on the filter plate 15. Since the filter plate 15 is tilted downwards and the direction of movement of the scraper 26 is opposite to the direction of sludge sliding out, the scraper 26 can more easily peel off the sludge on the filter plate 15 when the sludge after pressing is removed by gravity. This design can realize the cleaning of the filter plate at the same time during the sludge pressing process, so as to maintain the subsequent pressing effect and extend the service life of the core components of the device. Since the first telescopic rod 12 is equipped with a spring at the rotating connection of the pressure plate 14 and the initial position of the first telescopic rod 12 is not vertical, when the electric push rod 7 extends again, the slider 25 will move in the sliding groove 24 first, that is, the first telescopic rod 12 moves first rather than extends first.

[0020] Please refer to this carefully. Figures 2-4 The top of the filter press box 4 is provided with a movable groove 11. The top of the pressure plate 14 is fixedly connected to a second telescopic rod 13 located inside the movable groove 11. A second spring is installed inside the second telescopic rod 13. The top of the second telescopic rod 13 is fixedly connected to a connecting frame 10. The bottom of one side of the connecting frame 10 is fixedly connected to a first toothed plate 17. A discharge port 28 is provided on one side of the filter press 4. A sealing plate 8 is rotatably connected to the top of the discharge port 28. A first gear 18 that meshes with the first rack plate 17 is rotatably connected to the rear surface of the filter press 4. The top side of the sealing plate 8 is fixedly connected to the rear surface of the first gear 18.

[0021] In this embodiment: After the device has discharged the internal sludge, the electric push rod 7 is extended, causing the second telescopic rod 13 above the pressure plate 14 to move downward along the movable groove 11, and at the same time driving the connecting frame 10 to move downward, thereby causing the first rack plate 17 at the bottom of the connecting frame 10 to move downward. The first rack plate 17 rotates the first gear 18 synchronously. The rotation of the first gear 18 causes the sealing plate 8 to rotate in the discharge port 28, that is, the sealing plate 8 closes the discharge port 28 again. When the device injects sludge again, the electric push rod 7 is extended continuously, and the connecting frame 10 will be limited to the end of the movable groove 11. At the same time, the second telescopic rod 13 will extend. Since the second telescopic rod 13 is equipped with a second spring, when the electric push rod 7 retracts again, the second telescopic rod 13 will be reset and shortened first rather than moving upward along the movable groove 11 first. This design makes it easier for the device to discharge sludge and close the groove.

[0022] Please refer to this carefully. Figures 1-3 A collection box 9 located below the discharge port 28 is fixedly connected to one side of the filter press box 4; On the other side of the filter press box 4, there is an inlet 5 located below the filter plate 15, and on the other side of the filter press box 4, there is a sewage outlet 6 located below the filter plate 15. Solenoid valves are installed on one side of both the inlet 5 and the sewage outlet 6. A water gun 16 located inside the filter press box 4 is installed on one side of the inlet 5. The top of the dredging robot 1 is equipped with a mud pump 2. One end of the mud pump 2 is fixedly connected to a transport pipe 3, and the other end of the transport pipe 3 is fixedly connected to the other side of the filter press box 4. The other end of the transport pipe 3 is located above the filter plate 15.

[0023] In this embodiment: a dredging robot 1 is used to dredge the construction site. The dredging robot 1 uses a mud pump 2 to suck up the sludge and injects it into the filter press 4 through the transport pipe 3. After filtration, the sludge slides out from the top of the filter plate 15, and the filtrate accumulates at the bottom of the filter press 4 and is then discharged through the sewage outlet 6. The user can introduce cleaning water into the inlet 5 so that the water gun 16 sprays water backwashes the bottom of the filter plate 15, thereby cleaning the holes of the filter plate 15. The dredging robot 1 used in this invention can refer to the Schroder D600B.

[0024] Please refer to this carefully. Figure 3 , Figure 5 A second toothed plate 19 is fixedly connected to one side of the inner wall of the filter press 4, and a fixing block 27 is fixedly connected to the top of the pressure plate 14. A second gear 20 that meshes with the second rack plate 19 is rotatably connected to one side of the fixed block 27. A third telescopic rod 21 is rotatably connected to one side of the second gear 20. A rotating shaft 22 is rotatably connected to one side of the fixed block 27. The other end of the third telescopic rod 21 is fixedly connected to the outside of the rotating shaft 22. A striking rod 23 is fixedly connected to the outside of the rotating shaft 22. A soft rubber ball is fixedly connected to the end of the striking rod 23.

[0025] In this embodiment: when the pressure plate 14 moves past the second rack plate 19 on the inner wall of the filter press box 4, the second rack plate 19 will cause the second gear 20 to rotate, thereby driving the third telescopic rod 21 to move. The third telescopic rod 21 will synchronously cause the rotating shaft 22 to reciprocate. At the same time, the third telescopic rod 21 will extend and retract during the movement to cooperate with the transmission. The reciprocating rotation of the rotating shaft 22 will cause the striking rod 23 to swing back and forth, thereby striking the pressure plate 14, causing the silt stuck to the bottom of the pressure plate 14 to detach due to vibration. Since the striking rod 23 is made of soft rubber ball, damage to the pressure plate 14 can be avoided during long-term use.

[0026] Working principle: In the initial state, the slider 25 is located at the lower end of the sliding groove 24. When a certain amount of sludge is transferred to the filter press box 4, the electric push rod 7 is activated to extend, causing the pressure plate 14 at its output end to move downward. That is, the pressure plate 14 presses and filters the sludge to separate mud and water. During this process, the first telescopic rod 12 will retract. After the filtration is completed, the electric push rod 7 is activated to retract, and the pressure plate 14 moves upward synchronously. Since the first telescopic rod 12 is equipped with a first spring, when the pressure plate 14 moves upward, it will cooperate with the first spring to prioritize the reset of the first telescopic rod 12. Continuing to activate the electric push rod 7 to retract, the pressure plate 14 will drive the first telescopic rod 12 to move, which in turn will drive the slider 25 at the bottom of the first telescopic rod 12 to move in the sliding groove 24. At the same time, the scraper 26 at the bottom of the slider 25 scrapes the filter plate 15, thereby scraping off the residual sludge on the filter plate 15. This design can realize the simultaneous cleaning of the filter plate during the sludge filtration process. When the device has removed all the sludge inside... Then, the electric push rod 7 is extended, causing the second telescopic rod 13 above the pressure plate 14 to move downward along the movable groove 11, and at the same time driving the connecting frame 10 to move downward, which in turn causes the first rack plate 17 at the bottom of the connecting frame 10 to move downward. The first rack plate 17 synchronously rotates the first gear 18. The rotation of the first gear 18 causes the sealing plate 8 to rotate in the discharge port 28, that is, the sealing plate 8 closes the discharge port 28 again. This design makes it easier for the device to discharge sludge and close. When the movement of the pressure plate 14 passes the second rack plate 19 on the inner wall of the filter press box 4, the second rack plate 19 will cause the second gear 20 to rotate, which in turn drives the third telescopic rod 21 to move. The third telescopic rod 21 will synchronously cause the rotating shaft 22 to reciprocate. At the same time, the third telescopic rod 21 will extend and retract during the movement to cooperate with the transmission. The reciprocating rotation of the rotating shaft 22 will cause the striking rod 23 to swing back and forth, which will then strike the pressure plate 14, causing the sludge adhering to the bottom of the pressure plate 14 to detach due to vibration.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
