Description

Technical Field

[0001] The invention relates to the technical field of river channel cleaning, and in particular to a height-adjustable sediment collection device for assisting hydrological river channel cleaning. Background Art

[0002] Sediment collection devices for river cleaning are important tools in river management and underwater engineering. They can help to effectively collect sediment and silt from the riverbed for cleaning waterways.

[0003] After searching, the Chinese patent with the announcement number CN108797680B discloses a dredger's sediment collection device, including a dredger main pipe, a bypass pipe, two sand collecting wheels and a driving device. The two sand collecting wheels rotate synchronously and in opposite directions. The bypass pipe is bent and both ends are connected to the dredger main pipe. A one-way valve plate is provided at both ends of the bypass pipe. A piston is slidably connected in the dredger main pipe. The piston rod of the piston extends out of the dredger main pipe and is connected to the two sand collecting wheels through a transmission mechanism that enables the piston rod to reciprocate with the rotation of the two sand collecting wheels. A one-way valve plate 2 is provided at the inlet of the dredger main pipe. The dredger's sediment collection device proposed in the above scheme has a dredger's dredger's dredger main pipe and a dredger main pipe, wherein the dredger's dredger main pipe and the dredger main pipe are mutually coordinated working systems, which are simple to control and can make the two work or stop synchronously, thereby improving energy utilization. However, the above scheme still has the following shortcomings when actually used:

[0004] The sediment collection device proposed in the above scheme does not have the function of dehydrating the collected sediment. During the collection process, water is mixed in the sediment and collected together. Since the sediment collection device cannot dehydrate the sediment during the collection process, the water content of the collected sediment is usually high, which makes the subsequent processing process difficult, because the sediment with high water content is not easy to transport, store and reuse. In addition, the sediment with high water content is prone to produce odor and pollute the environment during the processing and storage process. If it is not handled properly or the storage conditions are not good, it may also cause the leakage and spread of harmful substances, posing greater risks to the surrounding environment and ecosystem.

[0005] Therefore, it is necessary to design a highly adjustable sediment collection device to assist in hydrological river channel cleaning to solve the above problems. Summary of the invention

[0026] The present invention has the following beneficial effects:

[0027] 1. By introducing a reciprocating linear drive module and the forward and reverse rotation design of two sieve drum structures, efficient dehydration of collected sediment is achieved. This innovative design can significantly reduce the water content of sediment, making the treated sediment easier to transport, store and reuse. At the same time, the dehydrated sediment reduces the generation of odor and reduces the risk of environmental pollution. More importantly, this solution effectively avoids the leakage and diffusion of harmful substances caused by high water content, which is of great significance to protecting the surrounding environment and ecosystem safety;

[0028] 2. By designing the water-pressing parts in the two screen drum structures, combined with the reciprocating movement of the rack and the coordinated action of the second gear, one-way bearing, threaded rod and other components, efficient water removal of sediment is achieved. This design not only generates centrifugal force to throw out water through the rotation of the screen drum, but also uses the intermittent downward pressure of the water-pressing plate to further squeeze out the water in the sediment. This dual water removal mechanism greatly improves the water removal effect and ensures that the water content of the treated sediment is significantly reduced. In addition, the design of the water-pressing plate also enhances the uniformity and thoroughness of sediment treatment;

[0029] 3. After the dewatering action is completed, the present invention drives the hydraulic cylinder to move through the sliding frame, so that the two outer cylinders are accurately positioned above the feeding hopper, and then the cylinder synchronously drives the telescopic frame to separate the outer cylinders to realize automatic unloading of the mud and sand. The vibration frame and crossbar structure arranged on the feeding hopper effectively screen out impurities such as stones in the mud and sand, ensuring the purity of the mud and sand. At the same time, the seamless connection between the mud and sand conveyor and the feeding hopper not only simplifies the mud and sand collection process, but also greatly improves the efficiency and convenience of mud and sand transportation. This series of designs not only optimizes the entire process of mud and sand treatment, but also improves the quality of the treated mud and sand, providing a reliable guarantee for the subsequent utilization of mud and sand, and realizing a one-stop efficient treatment from dewatering to screening to transportation;

[0030] 4. An actuator driven by an air supply is added to the feeding hopper, so that the vibration frame can produce an efficient vibration effect. This design brings multiple significant benefits. First, through the ingenious cooperation of the linear slide, the cross plate and the arc groove, the continuous up and down movement of the sliding rod is realized, thereby driving the gas exchange between the air supply and the actuator, providing a stable vibration power for the vibration frame. Secondly, the vibration of the vibration frame not only accelerates the screening process of sediment on the cross bar, but also ensures that the sediment can pass through the screen evenly and quickly, greatly improving the screening efficiency and screening quality. In addition, the vibration effect also helps to break up the lumps in the sediment, so that fine particles can be separated smoothly, further improving the purity and utilization rate of the sediment.

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Reference Figure 1-14, a height-adjustable sediment collection device for assisting hydrological river channel cleaning, comprising a gantry frame 1, a connecting structure, a sediment collection structure, a rotating structure, a driving structure, a water pressure structure, a downward pressure structure and a sediment transport structure, a sliding frame 2 is slidably mounted on the gantry frame 1, a hydraulic cylinder 3 is installed on the sliding frame 2, a connecting structure is arranged at the telescopic end of the hydraulic cylinder 3, the connecting structure comprises two telescopic frames 44 arranged opposite to each other, the connecting structure further comprises a top plate 41 and an outer frame 42, the top plate 41 is fixed to the telescopic end of the hydraulic cylinder 3, the top plate 41 and the outer frame 42 are connected by four connecting rods 43, the two telescopic frames 44 are respectively slidably arranged at the two ends of the outer frame 42, two cylinders 45 are installed on the top surface of the outer frame 42, and the telescopic ends of the two cylinders 45 are respectively fixedly connected to the two telescopic frames 44;

[0048] The sediment collection structure is composed of two sediment collection pieces, which are respectively connected to the two telescopic frames 44. Each sediment collection piece includes a sieve drum structure 53. Each sieve drum structure 53 includes two frames, a screen and a bottom plate. The two frames are respectively fixed at the upper and lower ends of the screen, and the bottom plate is fixed on the frame below. The two frames and the screen are both arc-shaped structures. When the two sediment collection pieces are aligned, the two screens together form a cylindrical structure, and the two bottom plates also together form a disc-shaped structure. The sediment collection piece also includes an outer cylinder 51, a plurality of drainage ports 52, a fixing frame 54 and a slot 55. The outer cylinder 51 is fixed to one end of the telescopic frame 44 away from the outer frame 42. The sieve drum structure 53 is arranged inside the outer cylinder 51. The plurality of drainage ports 52 are all opened at the bottom end of the outer cylinder 51. The fixing frame 54 is fixed on the sieve drum structure 53, and the fixing frame 54 is a U-shaped structure. The slot 55 is opened in the middle of the fixing frame 54, and a plug rod 56 is fixed inside the slot 55.

[0049] When the height-adjustable sediment collection device proposed by the present invention is used, the staff first arranges the gantry frame 1 on the river channel so that the gantry frame 1 spans the river channel. When collecting sediment in the river channel, the hydraulic cylinder 3 first operates and drives the top plate 41 to move downward. When the top plate 41 moves downward, the outer frame 42 can be driven downward through the four connecting rods 43, so that the two sediment collection pieces move downward synchronously until the two outer cylinders 51 move to the bottom of the river channel. At this time, the two outer cylinders 51 can be inserted into the sediment. Further, the two gas cylinders 51 are connected to the bottom of the river channel. The cylinder 45 operates and drives the two telescopic frames 44 to approach each other. When the two telescopic frames 44 approach each other, they can drive the two outer cylinders 51 to approach each other. In this process, the two outer cylinders 51 can shovel the silt into the inside of the two screens. When the two outer cylinders 51 are aligned, the two cylinders 45 stop operating. In this case, the two outer cylinders 51 can form a cylindrical structure together, and the two screens also form a cylindrical structure together. At this time, the silt and water will be located inside the cylindrical structure formed by the two screens, realizing automatic collection of the silt;

[0050] The rotating structure is arranged on the connecting structure, and is used to drive the two screen drum structures 53 to rotate. The rotating structure includes a rotating shaft 61, a first gear 62, two sleeves 63 and two grooves 64. The rotating shaft 61 passes through the outer frame 42 and is rotatably connected to the outer frame 42. The first gear 62 is fixedly sleeved on the top of the rotating shaft 61. The two sleeves 63 are fixedly sleeved on the bottom of the rotating shaft 61. The two grooves 64 are both opened on the rotating shaft 61, and the two grooves 64 are both located between the two sleeves 63.

[0051] After the sediment is collected, the hydraulic cylinder 3 drives the top plate 41 to move upward, and the two screens also move upward until the two outer cylinders 51 and the two screens are moved above the water surface. It should be noted that in the process of the two outer cylinders 51 approaching each other, the two fixing frames 54 will also approach each other. When the two fixing frames 54 are aligned, the two slots 55 jointly clamp the rotating shaft 61, and the insertion rod 56 in the slot 55 will also be inserted into the groove 64 on the rotating shaft 61. At this time, the two insertion rods 56 and the two grooves 64 play a role in connecting the rotating shaft 61 and the two fixing frames 54. In addition, two sleeves 63 are fixedly sleeved on the rotating shaft 61. When the two fixing frames 54 are aligned, the two fixing frames 54 are moved between the two sleeves 63. The two sleeves 63 limit the two fixing frames 54 in the vertical direction, prevent the two fixing frames 54 from shaking in the vertical direction, and ensure the connection stability between the rotating shaft 61 and the two fixing frames 54.

[0052] The driving structure is arranged on the gantry frame 1, and is used to drive the rotating structure to operate. The driving structure includes a reciprocating linear driving module 71, a linear slide 72 and a rack 73. The reciprocating linear driving module 71 is installed on the gantry frame 1, and the linear slide 72 is assembled on the reciprocating linear driving module 71. The rack 73 is fixed to the bottom surface of the linear slide 72. Teeth are arranged on both sides of the rack 73, and the teeth on one side of the rack 73 are arranged opposite to the first gear 62.

[0053] When the top plate 41 moves to the upper limit position, the first gear 62 just moves to the position opposite to the rack 73. Further, the reciprocating linear drive module 71 operates to drive the linear slide 72 to reciprocate. When the linear slide 72 moves, it can drive the rack 73 to reciprocate. When the rack 73 moves forward, the rack 73 will contact the first gear 62 and drive the first gear 62 to rotate forward. When the rack 73 moves backward, the rack 73 will contact the first gear 62 again and drive the first gear 62 to rotate backward. Therefore, the rack 73 can drive the first gear 62 to rotate forward and backward during the reciprocating movement. When rotating, it can drive the rotating shaft 61 to rotate, and the rotating shaft 61 will drive the two screen drum structures 53 to rotate synchronously through the two grooves 64 and the two plug rods 56. Based on the above process, during the operation of the reciprocating linear drive module 71, the cylindrical structure formed by the two screens will continuously rotate forward and reversely. In this process, the water mixed in the sediment will be thrown out from the screen under the action of centrifugal force, and the sediment will be retained in the cylindrical structure formed by the two screens. This design can remove water from the sediment. Further, the thrown-out water will flow out through the several drainage ports 52 on the two outer cylinders 51 and flow back into the river.

[0054] The water pressure structure is composed of two water pressure parts, which are respectively arranged inside the two sieve cylinder structures 53. The water pressure structure includes a connecting frame 81, a vertical plate 82, a lifting plate 83 and a water pressure plate 87. One end of the connecting frame 81 is fixed to the top surface of the outer cylinder 51, and the vertical plate 82 is fixed to the other end of the connecting frame 81. The lifting plate 83 is slidably assembled on the vertical plate 82, and the lifting plate 83 and the vertical plate 82 are connected by a tension spring. The lifting plate 83 is made of magnets, and the water pressure plate 87 is arranged on the lifting plate 83. The water pressure plate 87 is connected to the lifting plate 83 through a connecting spring 88. A limit opening 84 is provided on the vertical plate 82. A limit block 85 is fixed on the outer circumference of the lifting plate 83. The limit block 85 is slidably arranged in the limit opening 84, and one end of the limit block 85 away from the lifting plate 83 extends to the outside of the limit opening 84. Two anti-slip plates 86 are fixedly sleeved on the limit block 85. The two anti-slip plates 86 are respectively arranged on both sides of the vertical plate 82, and each anti-slip plate 86 is in contact with the vertical plate 82.

[0055] The downward pressure structure is arranged on one of the sediment collecting parts, and is used to drive the two water-pressing parts to operate. The downward pressure structure includes a side plate 91, a threaded rod 92, a movable plate 93, a pressure rod 94 and a second gear 95. The side plate 91 is fixed to the side of the fixed frame 54, the threaded rod 92 is rotatably mounted on the side plate 91, the movable plate 93 is threadedly sleeved on the threaded rod 92, one end of the pressure rod 94 is fixedly connected to the movable plate 93, the other end of the pressure rod 94 passes through the side plate 91, and is slidably connected to the side plate 91, the end of the pressure rod 94 away from the movable plate 93 is arranged opposite to the lifting plate 83, the second gear 95 is assembled on the top of the threaded rod 92 through a one-way bearing 96, and the second gear 95 is arranged opposite to the teeth on the other side of the rack 73;

[0056] In the present invention, in order to ensure the water removal effect of the device on silt, water pressure parts are provided in the two screen cylinder structures 53. When the two outer cylinders 51 are aligned, the two lifting plates 83 and the two water pressure plates 87 will also be aligned with each other. The two lifting plates 83 together form a disc-shaped structure, and the two water pressure plates 87 also together form a disc-shaped structure. Under the elastic force of the two tension springs, the two lifting plates 83 are both located at the top position of the outer cylinder 51. During the reciprocating movement of the rack 73, the teeth on the other side of the rack 73 will also mesh with the second gear 95, which enables the rack 73 to drive the second gear 95 to rotate in the forward and reverse directions. When the rotation direction of the second gear 95 is the same as the locking direction of the one-way bearing 96, the second gear 95 can drive the threaded rod 92 to rotate. When the rotation direction of the second gear 95 is opposite to the locking direction of the one-way bearing 96, the second gear 95 will rotate relative to the threaded rod 92, that is, the second gear 95 will not drive the threaded rod 92 to rotate. During the process, the threaded rod 92 will intermittently rotate in one direction. When the threaded rod 92 rotates, under the limiting action of the pressure rod 94, the threaded rod 92 can drive the movable plate 93 to move downward. When the movable plate 93 moves downward, it will drive the pressure rod 94 to move downward, so that the pressure rod 94 pushes the corresponding lifting plate 83 downward. Since the two lifting plates 83 are made of magnets, when the two lifting plates 83 are in contact, the two lifting plates 83 will be adsorbed together. Therefore, when one of the lifting plates 83 moves downward under the downward pressure of the pressure rod 94, the two lifting plates 83 will move downward synchronously, and the two water pressure plates 87 will also move downward accordingly. Based on the above process, with the reciprocating movement of the rack 73, the disc-shaped structure formed by the two water pressure plates 87 will intermittently move downward, so that the disc-shaped structure formed by the two water pressure plates 87 continuously presses down the mud and sand. The downward pressing action of the two water pressure plates 87 can squeeze out the water in the mud and sand, and at the same time, with the water throwing action, it can more fully remove the water mixed in the mud and sand.

[0057] During the movement of the lifting plate 83, the limiting opening 84 and the limiting block 85 limit the movement of the lifting plate 83 to ensure the stability of the lifting plate 83 during the movement. In addition, the two anti-slip plates 86 on the limiting block 85 can prevent the limiting block 85 from detaching from the limiting opening 84.

[0058] The sediment transport structure includes transport parts and vibrating parts. The transport parts include a sediment conveyor 101, a hopper 102, a vibrating frame 103 and a plurality of cross bars 104. The sediment conveyor 101 is installed on one side of the gantry frame 1, and the conveyor belt of the sediment conveyor 101 is inclined. The hopper 102 is fixed on the sediment conveyor 101, and the hopper 102 is arranged opposite to the conveyor belt of the sediment conveyor 101. The vibrating frame 103 is slidably assembled on the hopper 102. A plurality of cross bars 104 are fixed on the inner circle of the vibrating frame 103, and a plurality of cross bars 104 are distributed in a linear array. The vibrating frame 103 is connected to the hopper 102 by two vibrating springs 105. The vibrating parts include an air supply part 111, a bracket 112, an actuator 113, a connecting pipe 114, a fixing rod 115 and a cross plate 116. The air supply part 11 1 is fixed on the top surface of the linear slide 72, the bracket 112 is fixed on the side of the hopper 102, the actuator 113 is arranged on the bracket 112, and the actuator 113 is arranged opposite to the vibration frame 103, the air supply member 111 and the actuator 113 are connected through a connecting pipe 114, one end of the fixed rod 115 is fixedly connected to the gantry frame 1, and the other end is fixedly connected to the cross plate 116, the cross plate 116 is arranged opposite to the air supply member 111, and a plurality of arc grooves 117 are provided on the bottom surface of the cross plate 116, the air supply member 111 and the actuator 113 both include a sealing cylinder, a sliding rod and a reset spring, the sliding rod is movably inserted in the sealing cylinder, and one end of the sliding rod extends to the outside of the sealing cylinder, the sealing cylinder and the sliding rod are connected through a reset spring, the two sealing cylinders are connected through a connecting pipe 114, and the connecting pipe 114 is a hose;

[0059] After the water removal is completed, the hydraulic cylinder 3 is driven by the sliding frame 2 to move on the gantry frame 1 until the two outer cylinders 51 move to the top of the feeding hopper 102. At this time, the two cylinders 45 operate synchronously, so that the two telescopic frames 44 drive the two outer cylinders 51 to move away from each other. When the two outer cylinders 51 move away from each other, the mud and sand in the two screens will fall downward. A vibration frame 103 is provided on the feeding hopper 102, and a plurality of cross bars 104 are fixed on the vibration frame 103. The plurality of cross bars 104 together screen the mud and sand. When the silt falls on the plurality of cross bars 104, impurities such as stones in the silt will be stopped by the plurality of cross bars 104, and the silt will directly fall into the inside of the feeding hopper 102. The arrangement of the plurality of cross bars 104 can screen the impurities in the silt. Furthermore, the silt conveyor 101 is operated to drive the silt falling into the feeding hopper 102 to move. The staff connects the silt conveyor vehicle with the silt conveyor 101 to collect the sieved silt, which is convenient for the subsequent transportation of the silt.

[0060] The feeding hopper 102 is also provided with an actuator 113 for making the vibration frame 103 produce a vibration effect. The actuator 113 is driven by an air supply member 111, and the air supply member 111 is arranged on the linear slide 72. When the linear slide 72 moves to the bottom of the cross plate 116, the sliding rod in the air supply member 111 will contact the cross plate 116. When the sliding rod moves to a position facing the arc groove 117, the sliding rod will move upward and insert into the arc groove 117. When the sliding rod moves to a position between two arc grooves 117, the sliding rod will move downward along the groove wall of the arc groove 117. Therefore, under the action of several arc grooves 117, the sliding rod in the air supply member 111 will continuously move up and down. When the sliding rod in the air supply member 111 moves downward, the sliding rod can The gas in the sealing cylinder in the air supply part 111 is pressed into the sealing cylinder in the actuator 113 through the connecting pipe 114, which causes the sliding rod in the actuator 113 to move and push the vibration frame 103. When the sliding rod in the air supply part 111 moves upward, the sliding rod can extract the gas in the sealing cylinder in the actuator 113, which causes the sliding rod in the actuator 113 to reset, and the vibration frame 103 is also reset under the action of two vibration springs 105. Based on the above process, when the linear slide 72 moves to the bottom of the cross plate 116, the vibration frame 103 can produce a vibration effect under the cooperation of the air supply part 111 and the actuator 113. When the vibration frame 103 vibrates, the mud and sand accumulated on the several cross bars 104 can be quickly and evenly screened.
