[0002] In many fields such as environmental engineering, water conservancy engineering and land development, sediment drainage and consolidation is a vital task. Sediment usually refers to the soft material containing a large amount of water and various impurities deposited at the bottom of the water body. Effectively draining the water from the sediment and consolidating it is of great significance to improve the carrying capacity of the land, improve the quality of the water environment and ensure the safety of the project.

[0003] In the related art (Announcement No. CN106381835B), a rapid drainage and consolidation device for dredged sediment in rivers and lakes is disclosed, including a sediment container, the sediment container is a hollow structure, and one end is provided with an opening, the open end of the sediment container is provided with a hatch, one side of the hatch is rotatably connected to the sediment container through a rotating shaft, the upper end of the sediment container is provided with two mud injection holes, an exhaust fan is installed between the mud injection holes, and the inner cavity of the sediment container is provided with a load-bearing plate. The load-bearing plate and the super-strong woven cloth of the present invention are both water-permeable, the sludge is left above the load-bearing plate, the water penetrates to the bottom of the load-bearing plate, and is discharged from the outside of the device through vacuum pumping, the heating rod heats the sediment, reduces the accumulation of water inside the device, and also accelerates the consolidation speed of the sediment; when the sediment consolidation is completed, the hatch is opened to pull out the load-bearing plate through the traction device, and the consolidated sediment is transported to another place, and the device can also carry out the next sediment consolidation work.

[0004] At present, the existing sediment drainage and consolidation mainly relies on the natural sedimentation of the sediment to separate water from the sediment, thereby achieving the purpose of sediment drainage. This method relies on gravity to allow water to naturally infiltrate in the pores between the sediment particles. However, the above natural sedimentation process is extremely slow, especially for sediment with fine particles and low porosity, which causes the entire drainage and consolidation process to take too long, increasing the project cycle and cost. It will also cause a series of secondary problems such as microbial fermentation of the sediment and the production of harmful gases due to long-term water retention, making it difficult to meet the actual construction needs of sediment drainage projects.

[0027] Compared with the prior art, the sediment drainage consolidation device of the present invention has the following beneficial effects:

[0028] 1. With regard to the method of separating water from the bottom mud by natural sedimentation of the bottom mud, the sedimentation process is extremely slow, especially for the bottom mud with fine particles and low porosity, which causes the entire drainage consolidation process to take too long, increasing the engineering period and cost. The present invention applies pressure to the bottom mud and water mixture in the consolidation box by a downwardly moving pressing plate, and the pressure assists the water to quickly separate from the bottom mud, thereby realizing the accelerated separation of the bottom mud and water. The drainage effect is more obvious and effective for the bottom mud with fine particles and low porosity, shortening the drainage consolidation time and shortening the overall engineering construction period;

[0029] Second, with regard to the method of separating water from the bottom mud by means of the natural sedimentation of the bottom mud, the long-term water retention causes a series of secondary problems such as microbial fermentation of the bottom mud and the generation of harmful gases. The present invention is provided with a pressure-assisted bottom mud drainage function and a negative pressure-assisted drainage function. Through the cooperation of the permeable plate, the air guide hose and the negative pressure box, etc., the gas in the consolidation box can be negatively extracted to the outside, further accelerating the separation of the water in the inner cavity of the consolidation box from the bottom mud, prompting the bottom mud particles to be arranged more closely, and improving the consolidation effect. The pressure-assisted drainage and the negative pressure-assisted drainage can be used in combination simultaneously to achieve the dual accelerated separation of the bottom mud and water, avoiding the microbial fermentation of the bottom mud caused by long-term water retention, and can also discharge the gas generated by the fermentation in the consolidation box to the outside, thereby providing protection for the environment and quality of the bottom mud consolidation, reducing the risk of pollution to the surrounding water and soil, and better meeting the actual construction needs of the bottom mud drainage project;

[0030] 3. In view of the problem that the existing market usually needs to set up driving devices for pressure-assisted sediment drainage and negative pressure-assisted drainage separately, and the two driving devices have poor synergy and waste power energy, the present invention can realize synchronous transmission of power through the first rotating shaft, the swing arm, the first through groove, the first driving pin, the second through groove, and the second driving pin, that is, it can synchronously drive the pressure-assisted sediment drainage and the negative pressure-assisted drainage to play a role at the same time, and the same driving force can realize the synchronous opening of the two functions, avoiding the energy waste and increased equipment complexity caused by setting up independent power sources for the two functions, and can better ensure the synergy of equipment driving;

[0031] Fourth, in view of the existing market, when the first rotating shaft is usually driven directly by power to rotate continuously, the pressure plate continuously applies pressure to the mixture of sludge and water. The continuous pressure can easily compact the sludge quickly, resulting in premature clogging of the water discharge channel, and at the same time, the movable plate is prompted to continue to rise to perform negative pressure suction on the consolidation box, thereby not leaving enough reaction time for the pressure to discharge the water in the sludge. The present invention applies pressure intermittently according to a certain time interval and pressure cycle. The interval pressure drainage can give the water inside the sludge enough time to adapt to the pressure change and discharge it more effectively, so that the sludge has a certain time to redistribute and discharge the water after the pressure is released, thereby improving the drainage efficiency and drainage quality; similarly, in the interval negative pressure suction exhaust mode, the combination of water and gas inside the sludge can be better broken, creating more favorable conditions for the subsequent discharge of water;

[0032] 5. The present invention can realize the intermittent meshing of the rack with the gear by setting a motor, a drive shaft, a turntable and a limit groove, and promote the intermittent rotation of the gear. Through the intermittent rotation of the gear, the intermittent rotation of the second rotating shaft and the first rotating shaft is realized, and then the intermittent counterclockwise swing of the swing arm is realized, so as to ensure that the pressure plate realizes intermittent pressure drainage and the moving plate realizes intermittent negative pressure suction. The present invention can synchronously realize intermittent pressure drainage and intermittent negative pressure suction by controlling the intermittent rotation of the first rotating shaft, so as to ensure that the bottom mud and water are separated more effectively and the subsequent bottom mud consolidation is smoothly carried out;

[0033] Sixth, the present invention can synchronously drive the third driving pin and the connecting pin to move in the corresponding direction by setting the rotating disk and the limiting groove, so as to promote the synchronous action of the connecting rod and the rack, cooperate with the fourth driving pin, the connecting block and the sliding block, and realize the intermittent rotation of the first rotating shaft driven by the gear, that is, the intermittent rotation of the gear and the first rotating shaft is finally realized through the continuous rotation of the rotating disk, thereby realizing the intermittent pressure and drainage of the pressure plate and the intermittent negative pressure suction of the moving plate;

[0034] 7. The present invention is provided with a brake block, which can brake the undriven gear to prevent the gear from rotating or reversing autonomously, so as to ensure the stability of the gear without driving force, that is, to ensure that the positions of the pressure plate and the movable plate can remain stable when the intermittently rotating first shaft stops rotating;

[0035] 8. The present invention provides a third through slot on the lifting plate, which can leave enough space for the fourth driving pin on the connecting rod to move, thereby preventing the displacement of the fourth driving pin from being interfered with and restricted by the lifting plate;

[0036] 9. The present invention is provided with a clearance groove on the lifting plate, which can ensure that the second rotating shaft and the gear rotate normally without restriction without affecting the normal lifting and moving of the lifting plate;

[0037] 10. The present invention can cause the vertical plate to move in the horizontal direction intermittently through the first moving arm, the first connecting frame, the horizontal plate, the second vertical rod, the bracket, and the fifth driving pin, and then through the cooperation of the vertical plate, the translation rod, the inclined rod, etc., the first lever and the second lever can be moved synchronously to cause the first clamp block and the second clamp block to change and adjust the clamping state and the open state. The first clamp block and the second clamp block in the clamping state can cause the air guide hose to be clamped and closed, and at this time, the air guide hose cannot pass through the air. The first clamp block and the second clamp block in the open state can be released from the clamping effect on the air guide hose, and at this time, the air guide hose can pass through the air, thereby realizing the switching of ventilation and air blocking at the air guide hose, that is, ensuring the intermittent negative pressure suction and drainage operation in the negative pressure box;

[0038] XI. The vertical height ratio of the vertical through groove and the arc-shaped through groove of the present invention is 2 to 4:1, thereby ensuring that the fifth driving pin moves along the vertical through groove of the longer path for a longer time. At this time, the first clamp block and the second clamp block clamp the air hose tightly and close it. At this time, the air hose cannot pass through the air. The upward moving plate can promote the formation of a more stable negative pressure environment in the inner cavity of the negative pressure box. Then, when the fifth driving pin moves along the arc-shaped through groove of the shorter path, the first clamp block and the second clamp block are opened, that is, the ventilation state at the air hose is realized, ensuring that the negative pressure accumulated in the inner cavity of the negative pressure box instantly draws the gas in the consolidation box through the air hose to the negative pressure box, that is, the present invention can ensure that the negative pressure box is in an effective, stable and sufficient negative pressure state through the long-path arc-shaped through groove, so as to ensure that each time the air hose is opened, the gas in the consolidation box is discharged quickly and effectively;

[0039] 12. The present invention can limit the movement of the vertical plate in the horizontal direction through the first strip plate, the second strip plate and the cross bar, so as to ensure that the translation rod and the connection between the translation rod and the oblique rod move in the horizontal direction without displacement in the vertical direction;

[0040] 13. The present invention can realize the vertical movement of the lifting frame by means of the translation rod that moves in the horizontal direction in cooperation with the limit rod and the sleeve block, thereby realizing the movement of the first lever and the second lever along the inner cavity of the arc-shaped groove at the corresponding position, realizing the outward flipping of the first positioning seat and the second positioning seat, prompting the first clamping block and the second clamping block to flip outward and break away from the clamping effect on the air guide hose, and realizing the restoration of the shape of the air guide hose and ventilation by means of the elastic force of the air guide hose itself;

[0041] 14. In the present invention, through the intermittent rotation of the first rotating shaft, the left side pressure-assisted bottom mud drainage function and the right side negative pressure-assisted bottom mud drainage function can be realized synchronously, thereby realizing the upward negative pressure suction of the movable plate, the left and right reciprocating displacement of the vertical plate, the conversion and adjustment of the clamping state and the open state of the first clamping block and the second clamping block, and the conversion of the air-closing state and the ventilation state of the air guide hose. The various actions can be seamlessly connected without additional adjustment time, so that the entire bottom mud drainage consolidation process is smoother. At the same time, the realization of the linkage action makes the coordination between the various components more precise and synchronous, avoiding mistakes and errors caused by asynchronism, and there is no need to equip each action with a separate controller and drive device, which reduces the equipment downtime caused by compatibility problems or failures between multiple control components;

[0042] 15. The present invention is provided with a second movable arm, a third movable arm, a positioning hole, and a positioning pin, which can adjust the initial height and the descending stroke of the pressing plate, thereby being able to perform personalized pressure operation for bottom mud with different characteristics, and satisfying the drainage operation of bottom mud of different volumes in the consolidation box;

[0043] 16. In the present invention, the distance between the first rotating shaft and the right end of the swing arm is 2 to 3 times the distance between the first rotating shaft and the left end of the swing arm, thereby ensuring that when the swing arm rotates counterclockwise, the moving plate in the inner cavity of the negative pressure box has sufficient lifting space to ensure that a sufficient negative pressure environment is formed in the negative pressure box;

[0044] In summary, the present invention achieves accelerated separation of sediment and water by means of pressure-assisted water quickly separating from sediment. The drainage effect is more obvious and effective for sediment with fine particles and low porosity, shortens the drainage consolidation time, and shortens the overall engineering construction period. A negative pressure-assisted drainage function is also provided, and pressure-assisted drainage and negative pressure-assisted drainage can be used in combination simultaneously to achieve dual accelerated separation of sediment and water, avoid microbial fermentation of sediment caused by long-term water retention, and discharge the gas produced by fermentation in the consolidation box to the outside, thereby providing protection for the environment and quality of sediment consolidation and reducing the risk of pollution to surrounding water bodies and soil. In addition, intermittent pressure drainage can give the internal moisture of the sediment enough time to adapt to pressure changes and discharge more effectively, so that the sediment has a certain amount of time to redistribute and discharge moisture after the pressure is released, thereby improving drainage efficiency and drainage quality. , which can better break the combination of moisture and gas inside the bottom mud, and create more favorable conditions for the subsequent discharge of moisture; more importantly, the present invention can realize the synchronous function of the left side pressure-assisted bottom mud drainage function and the right side negative pressure-assisted drainage function, thereby realizing the linkage of a series of actions such as the upward negative pressure suction of the movable plate, the left and right reciprocating displacement of the vertical plate, the conversion and adjustment of the clamping state and the open state of the first clamping block and the second clamping block, and the conversion of the air-closing and ventilation states of the air guide hose. Each action can be seamlessly connected without the need for additional adjustment time, thereby making the entire bottom mud drainage and consolidation process smoother. At the same time, the realization of the linkage action makes the coordination between the various components more precise and synchronized, avoiding mistakes and errors caused by asynchrony, and does not need to be equipped with a separate controller and drive device for each action, thereby reducing equipment downtime caused by compatibility issues or failures between multiple control components.

At this time, the torsion spring 41 is forced to undergo elastic deformation, and the air guide hose 38 loses its clamping and limiting effect and restores to a ventilated state. When the movable plate 37 moves upward along the inner wall of the negative pressure box 3 to realize the negative pressure suction effect, the air in the consolidation box 1 is prompted to enter the space of the negative pressure box 3 below the movable plate 37 through the air guide hose 38, thereby assisting the rapid separation of water and bottom mud in the consolidation box 1 with the help of the negative pressure effect.

The two translation rods 56 moving toward the middle prompt the connection between the two inclined rods 55 and the second connecting seat 54 to move upward, so as to prompt the lifting frame 53 to move upward. At this time, the sleeve block 52 moves upward along the limit rod 51; through the upward movement of the lifting frame 53, the first lever 43 and the second lever 46 are driven to move upward along the inner cavity of the arc groove 50 at the corresponding position, so as to prompt the first positioning seat 42 and the second positioning seat 45 to drive the first clamp block 44 and the second clamp block 47 to flip upward and open, that is, to prompt the first clamp block 44 and the second clamp block 47 to gradually flip and disengage from the positioning of the outer wall of the air guide hose 38.

A positioning pin 69 is threadedly penetrated through the front side wall of the second movable arm 66, and the positioning pin 69 penetrates the inner cavity of one of the positioning holes 68. The bottom end of the third movable arm 67 extends into the inner cavity of the consolidation box 1 and is installed with a pressing plate 70.

A door body 75 is rotatably provided on the left side of the consolidation box 1. After the consolidated sludge is taken out from the door body 75, the equipment can be repeatedly used to separate the sludge and water and to perform sludge consolidation processing, so as to realize the recycling of the equipment.

[0074] Specific reference Figure 2 and Fig. 9As shown, the left end of the air guide hose 38 passes through and extends into the inner cavity of the consolidation box 1, and extends from bottom to top to the upper surface of the permeation plate 71. The permeation plate 71 is a permeation plate commonly used in the existing market for separating water and mud. Both water and gas can pass through the permeation plate 71 downward, and the bottom mud is blocked on the upper surface of the permeation plate 71. This is the prior art, and the present application does not excessively elaborate on and limit the permeation plate 71; through the negative pressure suction effect of the negative pressure box 3, the water in the consolidation box 1 is accelerated to be discharged quickly, and the gas is prompted to be discharged from the consolidation box 1 through the air guide hose 38.

[0075] The same driving force is used to realize the simultaneous activation of the two functions of pressure-assisted drainage and negative-pressure-assisted drainage, thus avoiding the energy waste and increased equipment complexity caused by setting up independent power sources for the two functions, and better ensuring the coordination of equipment driving; at the same time, by controlling the intermittent rotation of the first rotating shaft 5, the intermittent pressure drainage and the intermittent negative pressure suction can be realized synchronously, so as to ensure that the bottom mud and water are separated more effectively and ensure the smooth consolidation of the subsequent bottom mud; the air guide hose 38 can realize the switching between ventilation and air closing, that is, to ensure the intermittent negative pressure suction and drainage operation in the negative pressure box 3, and the long-path arc-shaped groove 62 can ensure that the negative pressure box 3 is in an effective, stable and sufficient negative pressure state, so as to ensure that each time the air guide hose 38 is opened, the gas in the consolidation box 1 can be discharged quickly and effectively.

[0076] Specifically, the distance between the first rotating shaft 5 and the right end of the swing arm 6 is 2 to 3 times the distance between the first rotating shaft 5 and the left end of the swing arm 6, thereby ensuring that the counterclockwise rotating first rotating shaft 5 can cause the moving distance of the first movable arm 33 to be greater than the moving distance of the second movable arm 66, thereby ensuring that when the swing arm 6 rotates counterclockwise, the movable plate 37 in the inner cavity of the negative pressure box 3 has sufficient lifting space to ensure that a sufficient negative pressure environment is formed in the negative pressure box 3.

[0077] In addition, by disassembling the brake block 30 as needed, after the equipment is used, the brake block 30 can be disassembled, and when the rack 21 is out of engagement with the outer wall of the gear 32, the gear 32 can be manually driven to reset in the reverse direction, thereby achieving the reset of the first rotating shaft 5, the pressure plate 70 and the movable plate 37.

[0078] It is worth mentioning that the consolidation box 1 is an existing equipment. As needed, a heating device available on the existing market can be set in the inner cavity of the consolidation box 1 to assist the rapid consolidation of the sludge. These are all existing technologies. Under the premise of not affecting the normal operation of the present equipment, relevant existing functions and equipment can be added according to the actual sludge drainage and consolidation needs. It only needs to meet the sludge drainage and consolidation needs. The above-mentioned existing technologies will not be repeated or limited here. While the movable plate 37 moves along the inner wall of the negative pressure box 3, it can ensure the sealing of the bottom space between the negative pressure box 3 and the movable plate 37. To achieve the above purpose, a sealing strip can be set at the contact point between the movable plate 37 and the inner side wall of the negative pressure box 3. This is an existing technology and can be set as needed. It can meet the requirement that the bottom space between the movable plate 37 and the negative pressure box 3 is in a sealed state. The air guide hose 38 is a hose on the market that can achieve an air guide function. It can be made of rubber and other materials. It can be forced to deform under the action of external force, and automatically restore to its initial state after the external force is removed to automatically achieve a ventilation state. It only needs to meet the above requirements. Feeding The inlet 72 is an existing device, and the feeding port 72 is provided with a sealing cover that can be opened and closed. The cover can be opened or closed as needed to flexibly meet the requirements of the introduction of the bottom mud and water mixture and the sealing state of the consolidation box 1 after the introduction; the drain valve 73 is an existing device, and the water in the consolidation box 1 can be discharged to the outside through the opened drain valve 73; the exhaust valve 74 is a commonly used air release valve in the existing market, and the air pressure in the negative pressure box 3 can be balanced through the opened exhaust valve 74, so that the equipment can be adjusted to the initial state after the equipment is completed; the motor 12 adopts a self-locking motor that can be locked at the output end commonly used in the market. When the output end is stopped, it can be self-locked and will not rotate under external force. The motor 12 is a commonly used forward and reverse motor in the market, and its output end can rotate forward or reverse according to the use requirements, and it can meet the above-mentioned use requirements; the torsion spring 41 is a commonly used torsion spring in the existing market, which can produce elastic deformation under the action of external force and can restore to the initial state after the external force is removed; the above-mentioned existing components are not described in detail here.

[0079] The working principle of a bottom mud drainage consolidation device in this embodiment is:

[0080] The mixture of the bottom mud and water to be consolidated is fed into the inner cavity of the consolidation box 1 through the open feeding port 72, and the upper cover of the feeding port 72 is closed to make the consolidation box 1 sealed. The equipment is operated: the driving shaft 13, the rotating disk 14 and the limiting groove 15 are synchronously rotated clockwise by the opened motor 12. Since the connecting rod 17 and the first support rod 16 are rotatably connected, and the limiting groove 15 is divided into two parts, the proximal groove and the distal groove, refer to Figure 6As shown, when the telecentric groove of the limiting groove 15 rotates to the corresponding third driving pin 18, the third driving pin 18 is prompted to swing upward with the first support rod 16 as the axis, that is, the connecting rod 17 is prompted to move a certain distance clockwise with the first support rod 16 as the axis. At this time, the fourth driving pin 19 on the right side of the connecting rod 17 swings downward, and the connecting block 23 and the slider 24 connected to the fourth driving pin 19 limit the limiting bar 22 to ensure that the right end of the rack 21 will not fall off, and at the same time as the fourth driving pin 19 moves downward, the lifting plate 25 and the brake block 30 are prompted to move downward. At this time, the brake block 30 is separated from the outer wall of the gear 32, and the gear 32 loses the brake. At the same time, the turntable 14 that continues to rotate clockwise prompts the connecting pin 20 to rotate clockwise, driving the left end of the rack 21 to move synchronously to the left side of the driving shaft 13. In this process, the rack 21 is displaced to the left, prompting the gear 32 meshing with the rack 21 to rotate counterclockwise for a certain distance, thereby driving the first rotating shaft 5 connected to the front side of the gear 32 The third driving pin 18 is swung downward with the first supporting rod 16 as the axis, that is, the fourth driving pin 19 at the right end of the connecting rod 17 is swung upward, driving the connecting block 23, the slider 24, the rack 21, the lifting plate 25, and the brake block 30 to move upward synchronously. At this time, the rotating turntable 14 causes the connecting pin 20 to rotate above the driving shaft 13. Under the joint action of the connecting pin 20, the connecting block 23, and the slider 24, the rack 21 is separated from the outer wall of the gear 32. At this time, the brake block 30 follows the lifting plate 25 to move upward and is engaged with the gap between the two adjacent teeth at the bottom end of the gear 32, so as to brake the gear 32, and ensure that the gear 32 is stable and no longer rotates at this time, that is, to ensure that the first rotating shaft 5 is stable and no longer rotates at this time. Through the above-mentioned linkage process, the intermittent counterclockwise rotation of the gear 32 and the first rotating shaft 5 and the braking when the rotation stops are realized;

[0081] During the intermittent counterclockwise rotation of the first rotating shaft 5, the left side pressure-assisted sludge drainage function and the right side negative pressure-assisted drainage function are realized synchronously: the counterclockwise rotation of the first rotating shaft 5 causes the swing arm 6 to rotate counterclockwise, so as to cause the first driving pin 8 to drive the second movable arm 66, the third movable arm 67, and the pressure plate 70 to move downward synchronously, and the pressure plate 70 is used to apply pressure to the sludge and water mixture in the consolidation box 1, so that the water is forced to quickly pass through the permeation plate 71 downward, and the sludge is blocked and stays on the upper surface of the permeation plate 71 to wait for subsequent consolidation, thereby realizing pressure-assisted sludge drainage; at the same time, the counterclockwise rotation of the first rotating shaft 5 causes the second driving pin 10 at the right end of the swing arm 6 to move upward The first movable arm 33, the first connecting frame 34, the horizontal plate 35, the first vertical rod 36 and the movable plate 37 move upward synchronously, and the movable plate 37 moves upward in close contact with the inner wall of the negative pressure box 3, and cooperates with the clamped air guide hose 38 to cause the inner cavity space of the negative pressure box 3 at the bottom of the movable plate 37 to be in a negative pressure state. When the air guide hose 38 is in a ventilated state, the gas in the consolidation box 1 can be drawn into the air guide hose 38, further accelerating the separation of the water in the inner cavity of the consolidation box 1 from the bottom mud, and causing the bottom mud particles to be arranged more closely, thereby realizing negative pressure assisted drainage; the above-mentioned pressure assisted drainage and negative pressure assisted drainage can be used in combination synchronously to realize the double accelerated separation of bottom mud and water;

[0082] When the first rotating shaft 5 moves upward, the two second vertical rods 60 are synchronously driven to rise together. During the rising process of the second vertical rods 60, the fifth driving pin 58 at the end of the bracket 59 is first moved along the vertical through slot 61. When the fifth driving pin 58 moves upward to the arc-shaped through slot 62, the vertical plate 57 is forced to move in the direction close to the negative pressure box 3, so as to promote the translation rod 56 and the connection between the translation rod 56 and the inclined rod 55 to move synchronously in the middle. The two translation rods 56 moving toward the middle promote the connection between the two inclined rods 55 and the second connecting seat 54 to move upward, so as to promote the lifting. The lowering frame 53 moves upward, and the sleeve block 52 moves upward along the limiting rod 51 at this time; the lifting frame 53 moves upward, driving the first lever 43 and the second lever 46 to move upward along the inner cavity of the arc-shaped groove 50 at the corresponding position, so as to prompt the first positioning seat 42 and the second positioning seat 45 to drive the first clamping block 44 and the second clamping block 47 to flip upward and open, that is, to prompt the first clamping block 44 and the second clamping block 47 to gradually flip and break away from the positioning of the outer wall of the air guide hose 38. At this time, the torsion spring 41 is forced to undergo elastic deformation, and the air guide hose 38 loses its clamping and limiting function and recovers. In the re-ventilation state, the movable plate 37 moves upward along the inner wall of the negative pressure box 3 to realize the negative pressure suction effect, which causes the air in the consolidation box 1 to enter the negative pressure box 3 space below the movable plate 37 through the air guide hose 38, thereby assisting the rapid separation of water and bottom mud in the consolidation box 1 with the help of negative pressure. Referring to the above principle, when the fifth driving pin 58 moves to the inner cavity of the vertical through groove 61 at the next position again, the vertical plate 57 is forced to move in the direction away from the negative pressure box 3, so as to cause the translation rod 56 and the connection between the translation rod 56 and the inclined rod 55 to move outward, so as to realize the second The connecting seat 54 and the lifting frame 53 move downward, and cooperate with the elastic force of the torsion spring 41 to prompt the first lever 43 and the second lever 46 to respectively drive the first positioning seat 42 and the second positioning seat 45 to restore the vertical state, that is, the first clamping block 44 and the second clamping block 47 re-clamp the gas guide hose 38, so that the gas guide hose 38 is in a closed state and cannot be ventilated. In this state, the moving plate 37 that continues to move upward forms a sufficient negative pressure environment in the inner cavity of the negative pressure box 3, so that the negative pressure discharge of the gas in the consolidation box 1 can be quickly and effectively realized when the gas guide hose 38 is ventilated next time;

[0083] The present invention uses pressure-assisted water to quickly separate from the sediment, thereby achieving accelerated separation of the sediment and water. The drainage effect is more obvious and effective for sediment with fine particles and low porosity, shortens the drainage consolidation time, and shortens the overall engineering construction period. It is also provided with a negative pressure assisted drainage function. The pressure assisted drainage and the negative pressure assisted drainage can be used in combination with each other to achieve dual accelerated separation of sediment and water, avoid the fermentation of sediment microorganisms caused by long-term water retention, and can also discharge the gas produced by fermentation in the consolidation box 1 to the outside, thereby providing protection for the environment and quality of sediment consolidation and reducing the risk of pollution to surrounding water bodies and soil. In addition, the interval pressure drainage can give the internal moisture of the sediment enough time to adapt to the pressure change and discharge it more effectively, so that the sediment has a certain time to redistribute and discharge the moisture after the pressure is released, thereby improving the drainage efficiency and drainage quality. In the interval negative pressure suction and exhaust method, it can better Breaking the combined state of moisture and gas inside the bottom mud creates more favorable conditions for the subsequent discharge of moisture; more importantly, the present invention can realize the simultaneous function of the left-side pressure-assisted bottom mud drainage function and the right-side negative pressure-assisted drainage function, thereby realizing the linkage of a series of actions such as the upward negative pressure suction of the movable plate 37, the left and right reciprocating displacement of the vertical plate 57, the conversion and adjustment of the clamping state and the open state of the first clamp block 44 and the second clamp block 47, and the conversion of the air-closing and ventilation states of the air guide hose 38. Each action can be seamlessly connected without the need for additional adjustment time, thereby making the entire bottom mud drainage and consolidation process smoother. At the same time, the realization of the linkage action makes the coordination between the various components more precise and synchronized, avoiding mistakes and errors caused by asynchrony, and there is no need to equip each action with a separate controller and drive device, thereby reducing equipment downtime caused by compatibility issues or failures between multiple control components.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
