Description

Technical Field

[0001] The present invention relates to the technical field of river dredging and sediment cleaning, and particularly to a river dredging and sediment cleaning device for water conservancy construction. Background Art

[0002] In the field of water conservancy construction, especially in river dredging and sediment cleaning, traditional operation methods rely on dredging and sediment cleaning vessels for operation. These vessels are usually equipped with suction devices to extract the silt at the bottom of the river to keep the river channel unobstructed and the water body clean. However, the design of traditional dredging and sediment cleaning vessels has significant technical limitations.

[0003] Firstly, the suction arms of traditional dredging and sediment cleaning vessels are usually fixed and cannot swing independently. This means that in order to expand the suction range, it is necessary to rely on the movement of the entire hull to achieve the fan-shaped coverage of the suction arm. This method is not only inefficient but also requires high technical skills from the operators because precise control of the hull's position and direction is needed to effectively cover the area to be cleaned. In addition, frequent adjustment of the hull's position increases the work complexity and time cost, and may also lead to unsatisfactory dredging effects, especially in narrow or curved river channels.

[0004] Secondly, due to the limitations of the hull's own size and mobility, it faces challenges in performing delicate operations such as avoiding damage to the riverbank or avoiding obstacles, which further restricts the application range and effectiveness of traditional dredging equipment.

[0005] Therefore, a river dredging and sediment cleaning device for water conservancy construction is needed to solve the above problems. Summary of the Invention

[0006] In order to solve the above problems, that is, to solve the problems of complex operation, unsatisfactory sediment cleaning effect and inflexible movement existing in the existing dredging and sediment cleaning devices, the present invention provides a river dredging and sediment cleaning device for water conservancy construction.

[0007] A river dredging and silt cleaning device for water conservancy construction, comprising a hull and an operation room. A controller is arranged in the operation room. A lifting plate is slidably installed at the bottom of the hull. A swinging mechanism is rotatably installed inside the lifting plate. A horizontal suction pipe is communicatively arranged at the front of the swinging mechanism. A stirring mechanism is arranged at the front end of the horizontal suction pipe. A vertical suction pipe is communicatively arranged at the top of the swinging mechanism. The horizontal suction pipe and the vertical suction pipe are communicated through the swinging mechanism. A driving mechanism is arranged at the side of the swinging mechanism. The driving mechanism is drivingly connected to the swinging mechanism. A centrifugal pump is arranged inside the hull. The top end of the vertical suction pipe is communicated with the centrifugal pump. A pressure stabilizing chamber, a water squeezing chamber and a storage chamber are opened inside the hull. The pressure stabilizing chamber and the storage chamber are both communicated with the water squeezing chamber; By slidably arranging a lifting plate at the bottom of the hull and arranging a horizontal suction pipe at the front of the swinging mechanism inside the lifting plate, when it is necessary to clean the silt in the river, only need to move the lifting plate down to a suitable position, and then pump the silt into the water squeezing chamber through the centrifugal pump for dehydration, and finally make the sludge enter the storage chamber for storage. Among them, when the slurry water passes through the swinging mechanism, it will drive the driving mechanism, and the driving mechanism will drive the swinging mechanism, so that the swinging mechanism drives the horizontal suction pipe to swing in a fan shape. This setting does not require the whole hull to swing during dredging and silt cleaning, and only need to control the hull to move forward step by step. It is flexible in action and simple in operation.

[0008] Preferably, an inward recessed groove is opened at the bottom of the hull. The lifting plate slides in the inward recessed groove. An oil filling hole is communicatively opened at the top of the inward recessed groove. A lifting slide rod is fixedly installed at the top of the lifting plate. The lifting slide rod slides in the oil filling hole. A first limiting chute is opened at the side of the oil filling hole. A first limiting slider is fixedly installed at the side of the lifting slide rod. The first limiting slider slides in the first limiting chute. An oil pump is arranged at the top of the hull. The oil pump is fluidly communicated with the top end of the oil filling hole; By filling oil into or sucking oil out of the oil filling hole through the oil pump, the lifting plate can be controlled to slide up and down through the lifting slide rod.

[0009] Preferably, the swing mechanism includes a turntable rotatably installed inside the lifting plate. A swing groove is formed on the front surface of the lifting plate, and the front surface of the turntable communicates with the outside through the swing groove. The horizontal suction pipe is fixedly installed on the front surface of the turntable and extends out of the lifting plate through the swing groove. Symmetrically arranged first flow cavities and second flow cavities are formed at positions near both sides inside the turntable. The front ends of the first flow cavity and the second flow cavity are both communicated with the rear end of the horizontal suction pipe. A converging cavity is formed at the central position inside the turntable. The rear ends of the first flow cavity and the second flow cavity are both communicated with the converging cavity. The vertical suction pipe is coaxially and fixedly installed on the top of the turntable, and the bottom end of the vertical suction pipe is communicated with the converging cavity.

[0010] Preferably, the stirring mechanism includes a mounting ring rotatably coaxial to the outer surface of the horizontal suction pipe near the front end. A plurality of stirring rods are fixedly installed on the outer surface of the mounting ring, and the front ends of the plurality of stirring rods are fixedly connected to a stabilizing plate. A motor is fixedly installed inside the turntable. The output shaft of the motor is coaxially and fixedly installed with a driving shaft through a coupling. The front end of the driving shaft passes through the horizontal suction pipe and is coaxially and fixedly connected to the stabilizing plate. The motor is connected to the power supply on the hull and the controller in the operation room. When the motor rotates, the stabilizing plate, the stirring rods and the mounting ring are driven to rotate through the driving shaft, so that the sludge and water are mixed to form slurry water, which is convenient for suction.

[0011] Preferably, the driving mechanism includes a first extrusion cavity and a second extrusion cavity, both of which are formed inside the lifting plate. The first extrusion cavity and the second extrusion cavity are respectively located on both sides of the turntable and communicate with the outer surface of the turntable. First extrusion plates and second extrusion plates are symmetrically and fixedly installed on both sides of the turntable. When the turntable does not rotate, the first extrusion plate and the second extrusion plate are respectively located at the middle positions inside the first extrusion cavity and the second extrusion cavity. The first extrusion plate and the second extrusion plate are respectively connected to the front ends of the first extrusion cavity and the second extrusion cavity through a second abutting spring and a third abutting spring. Second through holes and third through holes are respectively formed through the middle positions near the sides of the first flow cavity and the second flow cavity. The second through hole and the third through hole are respectively located on the back surfaces of the first extrusion plate and the second extrusion plate.

[0012] Preferably, rubber plates are arranged at positions near the rear ends on the inner sides of the first flow chamber and the second flow chamber. A first one-way valve and a second one-way valve are respectively arranged at the rear ends of the first flow chamber and the second flow chamber. A third electromagnetic valve and a fourth electromagnetic valve are respectively arranged at the front ends of the first flow chamber and the second flow chamber. A first sensor and a second sensor are respectively arranged on both sides of the swing groove. The third electromagnetic valve, the fourth electromagnetic valve, the first sensor and the second sensor are all electrically connected to the controller. By drivingly connecting the swing mechanism with the driving mechanism, when the third electromagnetic valve is opened, the fourth electromagnetic valve is closed, and the slurry water flows through the first flow chamber to the converging chamber. At the same time, the slurry water in the first flow chamber will flow into the first extrusion chamber and push the first extrusion plate to slide, thereby driving the turntable to rotate, causing the horizontal suction pipe to rotate towards the direction of the second sensor until the horizontal suction pipe touches the second sensor. Then the third electromagnetic valve is closed and the fourth electromagnetic valve is opened. The slurry water starts to enter the converging chamber through the second flow chamber and at the same time enters the second extrusion chamber. The horizontal suction pipe starts to rotate towards the direction of the first sensor and operates in this cycle, enabling the horizontal suction pipe to automatically swing under the flow of the slurry water, saving energy. Moreover, the horizontal suction pipe can only be driven to swing after the slurry at one position is pumped out, and it can automatically adjust the swinging speed according to the amount of slurry, effectively improving the dredging effect. The rubber plate can increase the pressure at the front ends of the two flow chambers, enabling the slurry water to better enter the extrusion chamber.

[0013] Preferably, a suction hole is formed at the top of the recessed groove. The vertical suction pipe slides in the suction hole. The top end of the suction hole is communicated with the front of the top of the pressure stabilizing chamber through a first communication hole. The centrifugal pump is in fluid communication with the first communication hole. The back of the top of the pressure stabilizing chamber is communicated with a position near the front of the bottom of the water squeezing chamber through a second communication hole. A first electromagnetic valve is arranged in the second communication hole. A lifting hole is formed at the bottom of the pressure stabilizing chamber. A piston rod is slidably installed in the lifting hole through a first abutting spring. The top end of the piston rod extends into the pressure stabilizing chamber and is fixedly installed with a piston plate. A second limiting chute is formed on the side of the lifting hole. A second limiting slider is fixedly installed on the side of the piston rod. The second limiting slider slides in the second limiting chute. By arranging a piston plate that can slide up and down in the pressure stabilizing chamber, when the slurry water entering the pressure stabilizing chamber cannot enter the water squeezing chamber temporarily due to the closing of the first electromagnetic valve, the slurry water can press the piston plate to slide down, ensuring that the centrifugal pump can continuously extract the external slurry water. After the first electromagnetic valve is opened, the first abutting spring pushes the piston plate to slide up and presses the slurry water in the pressure stabilizing chamber into the water squeezing chamber. This setting not only ensures the stable operation of the equipment but also is convenient for operation.

[0014] Preferably, the rear end of the bottom of the water squeezing cavity is communicated with the top of the storage cavity through a third communication hole. A first retracted cavity is formed on the front surface of the third communication hole. A plugging plate is slidably installed inside the first retracted cavity. A second electric telescopic rod is fixedly installed on the front surface of the first retracted cavity. The telescopic end of the second electric telescopic rod extends into the first retracted cavity and is fixedly connected to the front surface of the plugging plate. A drain hole is formed through the bottom of the rear end of the water squeezing cavity, and a second solenoid valve is arranged inside the drain hole.

[0015] Preferably, a squeezing sliding frame is slidably installed inside the water squeezing cavity. A filter cloth is fixedly installed on the back surface of the squeezing sliding frame. A first through hole is formed through the top of the front surface of the squeezing sliding frame. A first electric telescopic rod is fixedly installed on the front surface of the water squeezing cavity. The telescopic end of the first electric telescopic rod extends into the water squeezing cavity and is fixedly connected to the front surface of the squeezing sliding frame. When the front surface of the squeezing sliding frame fits with the front surface of the water squeezing cavity, the third communication hole is located behind the filter cloth. The front surface of the top of the water squeezing cavity is rotatably installed with a top cover through a first hinge shaft. A hinge plate is rotatably installed on the upper surface of the top cover near the rear end through a third hinge shaft. The hinge plate is in a shape of "7". A locking screw rod is installed through the vertical section of the hinge plate in a threaded manner. A locking screw hole matching the locking screw rod is formed on the back surface of the hull. By slidably installing a squeezing sliding frame inside the water squeezing cavity, during operation, the front surface of the squeezing sliding frame first fits with the front surface of the water squeezing cavity. The first solenoid valve is opened, and the second solenoid valve is closed. The plugging plate plugs the third communication hole. The slurry water enters the water squeezing cavity through the second communication hole. After the slurry water roughly fills about one-third of the water squeezing cavity, the first solenoid valve is closed. The first electric telescopic rod pushes the squeezing sliding frame to press against the slurry water. The filtered water flows to the front surface of the squeezing sliding frame through the first through hole. After the first electric telescopic rod extends a certain length, it starts to slowly retract. At this time, the third communication hole is quickly opened, and the sludge falls into the storage cavity. Then the third communication hole is quickly plugged. Then the second solenoid valve is opened. After the squeezing sliding frame slides forward a certain distance, the filtered water starts to be squeezed to the back surface through the first through hole and is discharged from the drain hole until the front surface of the squeezing sliding frame fits with the front surface of the water squeezing cavity again. The second solenoid valve is closed, and the first solenoid valve is opened. This cycle is repeated, which is convenient for operation. Among them, the first electric telescopic rod, the second electric telescopic rod, the first solenoid valve, and the second solenoid valve are all controlled by a controller in the operation room.

[0016] Preferably, one side of the storage cavity is a transparent end. A side cover is hinged to the top of the transparent end of the storage cavity through a second hinge shaft. Locking devices that match each other are arranged at the bottom end of the side cover and the side surface of the hull.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention slides a lifting plate at the bottom of the hull and arranges a transverse suction pipe on the front of the swing mechanism inside the lifting plate. When it is necessary to clean the silt in the river channel, only need to move the lifting plate down to a suitable position, and then pump the silt into the water squeezing cavity through a centrifugal pump for dehydration. Finally, the sludge enters the storage cavity for storage. When the slurry water passes through the swing mechanism, it will drive the driving mechanism, and the driving mechanism will drive the swing mechanism, so that the swing mechanism drives the transverse suction pipe to swing in a fan shape. This setting does not require the entire hull to swing during dredging, only need to control the hull to move forward step by step. It is flexible in movement and simple in operation.

[0018] 2. The present invention drives the swing mechanism and the driving mechanism to be connected. When the third solenoid valve is opened and the fourth solenoid valve is closed, the slurry water flows through the first flow cavity to the converging cavity. At the same time, the slurry water in the first flow cavity will flow into the first extrusion cavity and push the first extrusion plate to slide, thereby driving the turntable to rotate, so that the transverse suction pipe rotates towards the direction of the second sensor until the transverse suction pipe touches the second sensor. Then the third solenoid valve is closed and the fourth solenoid valve is opened. The slurry water starts to enter the converging cavity through the second flow cavity and enters the second extrusion cavity at the same time. The transverse suction pipe starts to rotate towards the direction of the first sensor and runs in this cycle, so that the transverse suction pipe can swing automatically under the flow of the slurry water, saving energy. And the transverse suction pipe can only be driven to swing after the slurry at one position is pumped out, and it can automatically adjust the swing speed according to the amount of slurry, which can effectively improve the dredging effect. Among them, the rubber plate can increase the pressure at the front ends of the two flow cavities, so that the slurry water can better enter the extrusion cavity.

[0019] 3. The present invention arranges a piston plate that can slide up and down in the pressure stabilizing cavity. When the slurry water entering the pressure stabilizing cavity cannot enter the water squeezing cavity temporarily due to the closing of the first solenoid valve, the slurry water can press the piston plate to slide down, so as to ensure that the centrifugal pump can continuously pump the external slurry water. After the first solenoid valve is opened, the first abutting spring pushes the piston plate to slide up and presses the slurry water in the pressure stabilizing cavity into the water squeezing cavity. This setting can not only ensure the stable operation of the equipment, but also is convenient for operation.

[0020] 4. In the present invention, an extrusion sliding frame is slidably installed inside the water squeezing cavity. During operation, the front surface of the extrusion sliding frame first fits with the front surface of the water squeezing cavity. The first solenoid valve is opened, and the second solenoid valve is closed. The sealing plate seals the third communication hole. The slurry water enters the water squeezing cavity through the second communication hole. After the slurry water roughly fills about one-third of the water squeezing cavity, the first solenoid valve is closed. The first electric telescopic rod pushes the extrusion sliding frame to press against the slurry water. The filtered water flows to the front surface of the extrusion sliding frame through the first through hole. After the first electric telescopic rod extends a certain length, it starts to slowly retract. At this time, the third communication hole is quickly opened, and the sludge falls into the storage cavity. Then the third communication hole is quickly sealed. Then the second solenoid valve is opened. After the extrusion sliding frame slides forward a certain distance, the filtered water starts to be squeezed to the back surface through the first through hole and discharged from the drain hole until the front surface of the extrusion sliding frame fits with the front surface of the water squeezing cavity again. The second solenoid valve is closed, and the first solenoid valve is opened, and this cycle is repeated, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0024] As Figure 1-2As shown in the figure, an embodiment of the present invention discloses a river dredging and silt removal device for water conservancy construction, including a hull 1 and an operation room 2. A controller is arranged in the operation room 2. A lifting plate 3 is slidably installed at the bottom of the hull 1. A swinging mechanism is rotatably installed inside the lifting plate 3. A horizontal suction pipe 4 is communicatively arranged at the front of the swinging mechanism. A stirring mechanism is arranged at the front end of the horizontal suction pipe 4. A vertical suction pipe 5 is communicatively arranged at the top of the swinging mechanism. The horizontal suction pipe 4 and the vertical suction pipe 5 are communicated through the swinging mechanism. A driving mechanism is arranged at the side of the swinging mechanism. The driving mechanism is drivingly connected to the swinging mechanism. A centrifugal pump 6 is arranged inside the hull 1. The top end of the vertical suction pipe 5 is communicated with the centrifugal pump 6. A pressure stabilizing chamber 7, a water squeezing chamber 8 and a storage chamber 9 are opened inside the hull 1. The pressure stabilizing chamber 7 and the storage chamber 9 are both communicated with the water squeezing chamber 8. When dredging the silt of the river, only need to move the lifting plate 3 down to a suitable position, and then pump the silt into the water squeezing chamber 8 through the centrifugal pump 6 for dehydration, and finally make the sludge enter the storage chamber 9 for storage. When the slurry water passes through the swinging mechanism, it will drive the driving mechanism, and the driving mechanism will drive the swinging mechanism, so that the swinging mechanism drives the horizontal suction pipe 4 to swing in a fan shape. This setting does not need to swing the whole hull 1 during dredging and silt removal, only need to control the hull 1 to move forward step by step. It is flexible in action and simple in operation.

[0025] As Figure 2 shown, an in-sunk groove 10 is opened at the bottom of the hull 1. The lifting plate 3 slides in the in-sunk groove 10. An oil filling hole 11 is communicatively opened at the top of the in-sunk groove 10. A lifting slide bar 12 is fixedly installed at the top of the lifting plate 3. The lifting slide bar 12 slides in the oil filling hole 11. A first limit chute 13 is opened at the side of the oil filling hole 11. A first limit slider 14 is fixedly installed at the side of the lifting slide bar 12. The first limit slider 14 slides in the first limit chute 13. An oil pump 15 is arranged at the top of the hull 1. The oil pump 15 is in fluid communication with the top end of the oil filling hole 11. By filling oil into or sucking oil out of the oil filling hole 11 through the oil pump 15, the lifting plate 3 can be controlled to slide up and down through the lifting slide bar 12.

[0026] As Figure 5As shown in the figure, the swinging mechanism includes a turntable 16. The turntable 16 is rotatably installed inside the lifting plate 3. A swinging groove 17 is formed on the front surface of the lifting plate 3. The front surface of the turntable 16 communicates with the outside through the swinging groove 17. The transverse suction pipe 4 is fixedly installed on the front surface of the turntable 16. The transverse suction pipe 4 extends out of the lifting plate 3 through the swinging groove 17. First flow cavities 18 and second flow cavities 19 are symmetrically formed at positions near both sides inside the turntable 16. The front ends of the first flow cavities 18 and the second flow cavities 19 are both communicated with the rear end of the transverse suction pipe 4. A converging cavity 20 is formed at the central position inside the turntable 16. The rear ends of the first flow cavities 18 and the second flow cavities 19 are both communicated with the converging cavity 20. The vertical suction pipe 5 is coaxially and fixedly installed on the top of the turntable 16. The bottom end of the vertical suction pipe 5 is communicated with the converging cavity 20.

[0027] As Figure 5-7 shown in the figure, the stirring mechanism includes a mounting ring 21. The mounting ring 21 rotates coaxially on the outer surface of the transverse suction pipe 4 near the front end. A plurality of stirring rods 22 are fixedly installed on the outer surface of the mounting ring 21. The front ends of the plurality of stirring rods 22 are fixedly connected to the stabilizing plate 23. A motor 24 is fixedly installed inside the turntable 16. The output shaft of the motor 24 is coaxially and fixedly installed with a driving shaft 25 through a coupling. The front end of the driving shaft 25 passes through the transverse suction pipe 4 and is coaxially fixedly connected to the stabilizing plate 23. Among them, the motor 24 is connected to the power supply on the hull 1 and the controller in the operation room 2. When the motor 24 rotates, the stabilizing plate 23, the stirring rods 22 and the mounting ring 21 are driven to rotate through the driving shaft 25, so that the sludge and water are mixed to form muddy water, which is convenient for suction.

[0028] As Figure 5 shown in the figure, the driving mechanism includes a first extrusion cavity 26 and a second extrusion cavity 27. The first extrusion cavity 26 and the second extrusion cavity 27 are both formed inside the lifting plate 3. The first extrusion cavity 26 and the second extrusion cavity 27 are respectively located on both sides of the turntable 16 and are communicated with the outer surface of the turntable 16. First extrusion plates 28 and second extrusion plates 29 are symmetrically and fixedly installed on both sides of the turntable 16. When the turntable 16 does not rotate, the first extrusion plates 28 and the second extrusion plates 29 are respectively located at the middle positions inside the first extrusion cavity 26 and the second extrusion cavity 27. The first extrusion plates 28 and the second extrusion plates 29 are respectively connected to the front ends of the first extrusion cavity 26 and the second extrusion cavity 27 through second abutting springs 30 and third abutting springs 31. Second through holes 32 and third through holes 33 are respectively formed through the middle positions near the sides of the first flow cavities 18 and the second flow cavities 19. The second through holes 32 and the third through holes 33 are respectively located on the back surfaces of the first extrusion plates 28 and the second extrusion plates 29.

[0029] As Figure 5As shown, rubber plates 34 are provided at positions near the rear ends on the inner sides of the first flow chamber 18 and the second flow chamber 19. A first one-way valve 35 and a second one-way valve 36 are respectively provided at the rear ends of the first flow chamber 18 and the second flow chamber 19. A third solenoid valve 37 and a fourth solenoid valve 38 are respectively provided at the front ends of the first flow chamber 18 and the second flow chamber 19. A first sensor 39 and a second sensor 40 are respectively provided on both sides of the swing groove 17. The third solenoid valve 37, the fourth solenoid valve 38, the first sensor 39 and the second sensor 40 are all electrically connected to the controller. By drivingly connecting the swing mechanism and the driving mechanism, when the third solenoid valve 37 is opened, the fourth solenoid valve 38 is closed, and the slurry water flows through the first flow chamber 18 to the converging chamber 20. At the same time, the slurry water in the first flow chamber 18 will flow into the first extrusion chamber 26 and push the first extrusion plate 28 to slide, thereby driving the turntable 16 to rotate, causing the transverse suction pipe 4 to rotate in the direction of the second sensor 40 until the transverse suction pipe 4 touches the second sensor 40. Then the third solenoid valve 37 is closed, the fourth solenoid valve 38 is opened, and the slurry water starts to enter the converging chamber 20 through the second flow chamber 19. At the same time, it enters the second extrusion chamber 27, and the transverse suction pipe 4 starts to rotate in the direction of the first sensor 39. This cycle runs, enabling the transverse suction pipe 4 to automatically swing under the flow of the slurry water, saving energy. Moreover, the transverse suction pipe 4 can only be driven to swing after the slurry at one position is pumped out, and it can automatically adjust the swinging speed according to the amount of slurry, effectively improving the dredging effect. Among them, the rubber plate 34 can increase the pressure at the front ends of the two flow chambers, enabling the slurry water to better enter the extrusion chamber.

[0030] As Figure 2As shown, a suction hole 41 is formed at the top of the recessed groove 10. The vertical suction pipe 5 slides within the suction hole 41. The top end of the suction hole 41 is connected to the front of the top of the pressure stabilizing chamber 7 through a first communication hole 42. The centrifugal pump 6 is in fluid communication with the first communication hole 42. The back of the top of the pressure stabilizing chamber 7 is connected to a position near the front of the bottom of the water squeezing chamber 8 through a second communication hole 43. A first electromagnetic valve 44 is arranged within the second communication hole 43. A lifting hole 45 is formed at the bottom of the pressure stabilizing chamber 7. A piston rod 47 is slidably installed within the lifting hole 45 through a first abutting spring 46. The top end of the piston rod 47 extends into the pressure stabilizing chamber 7 and is fixedly installed with a piston plate 48. A second limiting chute is formed at the side of the lifting hole 45. A second limiting slider is fixedly installed at the side of the piston rod 47. The second limiting slider slides within the second limiting chute. By arranging a piston plate 48 that can slide up and down within the pressure stabilizing chamber 7, when the slurry water entering the pressure stabilizing chamber 7 cannot enter the water squeezing chamber 8 temporarily due to the closing of the first electromagnetic valve 44, the slurry water can press the piston plate 48 to slide down, thereby ensuring that the centrifugal pump 6 can continuously extract the external slurry water. After the first electromagnetic valve 44 is opened, the first abutting spring 46 pushes the piston plate 48 to slide up to press the slurry water within the pressure stabilizing chamber 7 into the water squeezing chamber 8. This setting can not only ensure the stable operation of the equipment but also facilitate the operation.

[0031] As Figure 2 shown, the rear end of the bottom of the water squeezing chamber 8 is connected to the top of the storage chamber 9 through a third communication hole 49. A first constricted chamber 50 is formed at the front of the third communication hole 49. A blocking plate 51 is slidably installed within the first constricted chamber 50. A second electric telescopic rod 52 is fixedly installed at the front of the first constricted chamber 50. The telescopic end of the second electric telescopic rod 52 extends into the first constricted chamber 50 and is fixedly connected to the front of the blocking plate 51. A drain hole 53 is formed through the bottom of the rear end of the water squeezing chamber 8. A second electromagnetic valve 54 is arranged within the drain hole 53.

[0032] As Figure 2-3 and Figure 8As shown in the figure, an extrusion sliding frame 55 is slidably installed inside the water squeezing cavity 8. A filter cloth 56 is fixedly installed on the back surface of the extrusion sliding frame 55. A first through hole 57 is formed through the top of the front surface of the extrusion sliding frame 55. A first electric telescopic rod 58 is fixedly installed on the front surface of the water squeezing cavity 8. The telescopic end of the first electric telescopic rod 58 extends into the water squeezing cavity 8 and is fixedly connected to the front surface of the extrusion sliding frame 55. When the front surface of the extrusion sliding frame 55 is in contact with the front surface of the water squeezing cavity 8, the third communication hole 49 is located behind the filter cloth 56. The front surface of the top of the water squeezing cavity 8 is rotatably installed with a top cover 60 through a first hinge shaft 59. A hinge plate 62 is rotatably installed on the upper surface of the top cover 60 near the rear end through a third hinge shaft 61. The hinge plate 62 is in a shape of "7". A locking screw 63 is threadedly installed through the vertical section of the hinge plate 62. A locking screw hole 64 matching the locking screw 63 is formed on the back surface of the hull 1. By slidably installing the extrusion sliding frame 55 inside the water squeezing cavity 8, during operation, the front surface of the extrusion sliding frame 55 first contacts the front surface of the water squeezing cavity 8. The first solenoid valve 44 is opened, and the second solenoid valve 54 is closed. The plugging plate 51 plugs the third communication hole 49. The slurry water enters the water squeezing cavity 8 through the second communication hole 43. After the slurry water roughly fills about one-third of the water squeezing cavity 8, the first solenoid valve 44 is closed. The first electric telescopic rod 58 pushes the extrusion sliding frame 55 to press against the slurry water. The filtered water flows to the front surface of the extrusion sliding frame 55 through the first through hole 57. After the first electric telescopic rod 58 extends a certain length, it starts to slowly retract. At this time, the third communication hole 49 is quickly opened, and the sludge falls into the storage cavity 9. Then the third communication hole 49 is quickly plugged. Then the second solenoid valve 54 is opened. After the extrusion sliding frame 55 slides forward a certain distance, the filtered water starts to be squeezed to the back surface through the first through hole 57 and is discharged from the drain hole 53 until the front surface of the extrusion sliding frame 55 is in contact with the front surface of the water squeezing cavity 8 again. The second solenoid valve 54 is closed, and the first solenoid valve 44 is opened. This cycle is repeated, which is convenient for operation. Among them, the first electric telescopic rod 58, the second electric telescopic rod 52, the first solenoid valve 44, and the second solenoid valve 54 are all controlled by the controller in the operation room 2.

[0033] As Figure 1 shown, one side of the storage cavity 9 is a through end. The top of the through end of the storage cavity 9 is hinged with a side cover 66 through a second hinge shaft 65. A lock 67 that matches each other is arranged between the bottom end of the side cover 66 and the side surface of the hull 1.
