Description

Technical Field

[0001] This invention relates to a device for uniformly distributing and guiding soil within a dredging barge compartment. Background Technology

[0002] In existing fixed-pile placement pipe designs for dredging and barge loading, the long, fixed branch pipes installed to extend the placement range become obstacles after loading, hindering equipment such as grab buckets from extracting excavated soil from the hopper. Furthermore, if multiple discharge ports are installed on the branch pipes, when it's necessary to direct slurry to more distant end branch pipes, the nearest discharge ports must be closed one by one, a cumbersome operation that makes ensuring a tight seal difficult. Moreover, for multiple heavy slurry branch pipes, manually adjusting their positions individually is both laborious and difficult to synchronize, impacting operational efficiency.

[0003] Therefore, a soil distribution and diversion device for uniformly distributing soil within the dredging and loading barge is proposed to address the above issues. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by providing a uniform soil distribution and diversion device for dredging barges, which can solve the problems mentioned in the background art, such as the fixed diversion pipe obstructing the barge and the difficulty in adjustment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil uniform distribution and diversion device in the dredging barge compartment, comprising: Distributed pipe fittings are installed on uprights to cover the hull openings; The distribution pipe fitting includes a main pipe and a first branch pipe that are interconnected; The port of the first branch pipe is connected to the second branch pipe through a hinge structure. The second branch pipe can switch between an unfolded position aligned with the first branch pipe and a folded position that rotates relative to the first branch pipe. A first discharge pipe is provided on the wall of the first branch pipe; A branch valve is provided at the connection channel between the first branch pipe and the second branch pipe, and a discharge valve is provided inside the first discharge pipe; When the second branch pipe switches from the folded position to the unfolded position, the branch pipe valve opens, and the discharge valve closes simultaneously.

[0006] Preferably, the branch valve is a ball valve with a branch ball valve wheel, and the discharge valve is a ball valve with a discharge ball valve wheel.

[0007] Preferably, a male hinge seat is fixed to the surface of the first branch pipe, and a secondary hinge seat is fixed to the surface of the second branch pipe. The secondary hinge seat is rotatably connected to the male hinge seat through a hinge shaft. An extension shaft is fixed to the end of the hinge shaft, and a disc-shaped shaft is fixed to the end of the extension shaft. The disc-shaped shaft is synchronously connected to the valve wheel of the branch ball valve via an active connecting rod.

[0008] Preferably, the surface of the branch ball valve wheel is fixed with an active sector-shaped tooth block, and the surface of the discharge ball valve wheel adjacent to the branch ball valve wheel is fixed with a driven sector-shaped tooth block, the active sector-shaped tooth block and the driven sector-shaped tooth block meshing with each other.

[0009] Preferably, it also includes a linkage component, which includes an end rod fixedly connected to a plurality of second branch pipes for synchronously driving the plurality of second branch pipes to switch between the unfolded position and the folded position.

[0010] Preferably, the linkage assembly further includes an arc-shaped guide rail fixed on the deck; the end of the end rod is fixed with a sliding shaft, which passes through the arc-shaped guide rail and can slide along its arc.

[0011] Preferably, it also includes a frame structure composed of a hollow rod and a connecting rod, wherein the portion of the sliding shaft passing through the arc-shaped guide rail is slidably disposed within the cavity of the hollow rod.

[0012] Preferably, it also includes a driving component, which includes a guide rod fixed on the deck and a hydraulic telescopic rod that provides linear reciprocating power. The connecting rod is slidably engaged with the guide rod through a connecting sleeve, and the driving end of the hydraulic telescopic rod is fixedly connected to the connecting rod.

[0013] Preferably, the driving component further includes a top plate fixed to the upper end of the guide rod, and the cylinder of the hydraulic telescopic rod is fixed to the top plate.

[0014] Preferably, the arc-shaped guide rail is fixed to the deck by a tripod, and the tripod is reinforced with diagonal bracing.

[0015] Compared with existing technologies, the advantages of this invention are: By using a "foldable second branch pipe," it can be unfolded at the end of the material spreading process to expand the coverage area; it can be folded during sludge pumping and hull cleaning to free up top working space for the sludge pumping equipment, resolving the contradiction of fixed long pipes hindering operations; simultaneously, utilizing the mechanical action of hinge shaft rotation, through the transmission of connecting rods and sector-shaped toothed blocks, while unfolding the second branch pipe, the main channel of the branch pipe is automatically opened and the drain hole on the first branch pipe is simultaneously closed, ensuring that the sludge is directed to the end. A single action simultaneously completes the mechanical unfolding and the logical switching of the internal valve channels.

[0016] Furthermore, through the linkage component, all second branch pipes can be driven to fold or unfold synchronously with only one hydraulic power source, which significantly improves the automation level and operating efficiency of the equipment. At the same time, the rubber sealing ring at the branch pipe joint is deformed under pressure to fill the gap, preventing sand-containing mud from eroding the hinges and joints and extending the service life.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the soil distribution and diversion device inside the dredging barge compartment: The entire distribution pipe fitting 1 is mounted on the deck via a support 11 to cover the opening of the hull. The distribution pipe fitting 1 consists of an interconnected main pipe 12 and a first branch pipe 13, with a second branch pipe 14 hinged to the end of the first branch pipe 13. The main pipe 12 has a flange interface for connecting to the dredging vessel's discharge pipe, thus the slurry is diverted through the main pipe 12 and discharged from the first branch pipe 13 connected to the main pipe 12. Multiple first discharge pipes 17 are opened on the surface of the first branch pipe 13, further diverting the slurry-like soil, thereby achieving... To ensure even distribution of soil and prevent soil from accumulating in one place inside the compartment; at the same time, the position of the second branch pipe 14 relative to the first branch pipe 13 can be adjusted, so when the second branch pipe 14 is aligned with the port of the first branch pipe 13, the second branch pipe 14 can participate in guiding and diverting the flow, thereby expanding the distribution range of the overall structure; and the second branch pipe 14 is unfolded and then distributed after the distribution of soil in the area covered by the first branch pipe 13 is completed; at the same time, when the soil in the compartment is subsequently extracted, the second branch pipe 14 can be folded relative to the first branch pipe 13 to leave space for easy discharge of the mud-like soil inside.

[0021] Example 1: A male hinge seat 15 is fixed to the surface of the first branch pipe 13, and a secondary hinge seat 16 is fixed to the surface of the second branch pipe 14. A hinge shaft 116, fixed to the insertion end of the secondary hinge seat 16 into the male hinge seat 15, is rotatably connected to the male hinge seat 15, thus achieving a hinge-type connection. Ball valves are installed at the joint ends of the first branch pipe 13 and the second branch pipe 14, and inside the first discharge pipe 17 of the first branch pipe 13. The discharge ball valve wheel 19 of the ball valve corresponding to the first discharge pipe 17 is connected via a driven connecting rod 110, and is connected to the first... The surface of the branch ball valve wheel 113 corresponding to the branch pipe 13 is fixed with an active sector tooth block 112, and the surface of the discharge ball valve wheel 19 adjacent to the branch ball valve wheel 113 is fixed with a driven sector tooth block 111. The driven sector tooth block 111 and the active sector tooth block 112 are meshed and connected to each other. Meanwhile, an extension shaft 117 is fixed at the end of the hinge shaft 116, and a disc shaft 115 is fixed at the end of the extension shaft 117. The disc shaft 115 and the branch ball valve wheel 113 are also synchronously connected by an active connecting rod 114.

[0022] Therefore, during the process of the second branch pipe 14 changing from a folded state to a horizontal state aligned with the first branch pipe 13: Driven by the active connecting rod 114, the branch pipe ball valve wheel 113 rotates with the second branch pipe 14. At this time, the branch pipe ball valve wheel 113 rotates in the forward direction, opening the ball valve inside the first branch pipe 13. Under the drive of the driven sector tooth block 111 and the active sector tooth block 112, which are of the same size and mesh with each other, the discharge ball valve wheel 19 rotates in the reverse direction, closing the ball valve inside the first discharge pipe 17. This ensures that after the second branch pipe 14 is aligned with the first branch pipe 13, directional flow is achieved, ensuring that the subsequent mud is evenly distributed through the second discharge pipe 18 of the second branch pipe 14. When the entire second branch pipe 14 is folded back, the above structure moves in the opposite direction. After the second branch pipe 14 is folded up at ninety degrees, the ball valve inside the first branch pipe 13 is closed, while the ball valve inside the first discharge pipe 17 is open.

[0023] In one specific embodiment: the interface between the second branch pipe 14 and the first branch pipe 13 is fitted with a rubber sealing ring 118. After the two are aligned, the sealing ring 118 is deformed by pressure to fill the gap and prevent leakage.

[0024] In one specific embodiment, both ends of the driven link 110 and both ends of the driving link 114 are provided with eccentric shafts, which are rotatably connected to the corresponding structures through the eccentric shafts, thereby achieving the effect of synchronous transmission.

[0025] Example 2: The linkage component 2 is integrated at the closed end of the second branch pipe 14. By using the end rod 21 which is fixedly connected to multiple second branch pipes 14, the position of multiple second branch pipes 14 can be adjusted at the same time to achieve the effect of quick alignment or quick folding and retraction.

[0026] A sliding shaft 26 is fixed at the end of the end rod 21, which can slide along the arc-shaped guide rail 22. The part of the sliding shaft 26 that passes through the arc-shaped guide rail 22 can slide along the cavity of the hollow rod 23. The arc-shaped guide rail 22 is fixed to the deck by a tripod 25, and a connecting rod 24 is fixed at the end of the hollow rod 23. Two connecting rods 24 and two hollow rods 23 are provided to form a frame structure, which is set above the deck. At the same time, a connecting sleeve 27 that has a sliding fit with the guide rod 31 of the drive component 3 is fixed on the side of the connecting rod 24. The drive component 3 is then used to assemble the rod onto the deck.

[0027] Therefore, when the entire hollow rod 23 slides upward, it can push the sliding shaft 26, the end rod 21, and even the second branch pipe 14 to slide along the arc-shaped guide rail 22. Since the center of the arc-shaped guide rail 22 coincides with the axis of the hinge shaft 116, the second branch pipe 14 can make a circular motion around the axis of the hinge shaft 116. Furthermore, the two ends of the arc-shaped guide rail 22 are subject to limit and close treatment to restrict the rotation range of the second branch pipe 14 to within ninety degrees, so as to avoid excessive movement that could damage the device.

[0028] Example 3: The guide rod 31 of the drive component 3 is directly fixed to the deck. The top plate 32 is fixed to the upper end of the guide rod 31. The hydraulic telescopic rod 33, which drives the movement of the entire mechanism, is fixed to the top surface of the top plate 32. The output shaft of the hydraulic telescopic rod 33 passes through the top plate 32 and is fixedly connected to the connecting rod 24. Therefore, after the hydraulic telescopic rod 33 is started, the connecting rod 24 and the hollow rod 23 can slide up and down along the guide rod 31, thereby driving the movement of the second branch pipe 14.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
