Description

Technical Field

[0001] This utility model relates to the field of geotextile tube bag technology, and in particular to a geotextile tube bag that is easy to fill and dredge underwater. Background Technology

[0002] Geotextile tubes are tubular or bag-shaped structures made primarily of high-strength geotextiles through sewing or hot-melt splicing. They are mainly used in engineering scenarios such as water dredging, sludge treatment, land reclamation, and coastal protection. Their core function is to fill the tubes with fluid containing solid particles, utilizing the permeability of geotextiles to filter water and retain solid particles, ultimately allowing the filled material to solidify into a structure with a certain strength and stability. Traditional underwater dredging often faces problems such as low filling efficiency, difficulty in positioning the tubes, slow sludge dewatering, and cumbersome installation and disassembly. Therefore, there is a particular need for geotextile tubes that are easy to fill for underwater dredging.

[0003] However, traditional geotextile bags have fixed-size drainage holes, which cannot dynamically adjust the drainage efficiency according to the silt concentration. At low concentrations, fine particles are easily lost, while at high concentrations, poor drainage leads to a longer filling cycle. In addition, the interfaces are mostly bolted, and installation and disassembly in a humid underwater environment require repeated diving operations, which is not only time-consuming and labor-intensive, but also prone to affecting the sealing performance due to bolt corrosion.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a geotextile tube bag that is easy to fill and dredge underwater, including a tube bag 1, with sealing gaskets 2 connected to both ends of the tube bag 1, a first flange interface 3 connected to the outer end of the sealing gaskets 2, strip-shaped flow guide holes 4 provided on the surface of the tube bag 1, a permeable geomembrane 5 provided inside the strip-shaped flow guide holes 4, a connecting rope 6 connected to the outer side of the tube bag 1, a counterweight block 7 connected to the bottom of the connecting rope 6, a traction rope 8 connected to the outer side of the first flange interface 3, a float-type positioning mark 9 connected to the end of the traction rope 8, and a quick docking assembly 10 provided on the surface of the first flange interface 3; The quick-connect assembly 10 includes a second flange interface 1001, which is mounted on the surface of a first flange interface 3. A first positioning block 1002 is connected to the side of the first flange interface 3, and a second positioning block 1003 is connected to the side of the second flange interface 1001. A limiting rotating plate 1004 is rotatably connected to the bottom of the first positioning block 1002. A tension cylinder 1005 is connected above the limiting rotating plate 1004. A tension groove 1006 is formed inside the tension cylinder 1005. A pull rod 1007 is slidably connected to the inner wall of the tension groove 1006. A guide block 1008 is connected to the bottom side of the pull rod 1007. A guide groove 1009 is formed inside the tension groove 1006. A telescopic spring 1 is connected to the outer side of the pull rod 1007. 010, a pull plate 1011 is connected to the top of the pull rod 1007, and a locking block 1012 is connected to the bottom side of the other end of the pull plate 1011. A slot 1013 is formed on the surface of the second positioning block 1003. A positioning hole 1014 is formed through the surfaces of the pull plate 1011 and the locking block 1012. A tension spring 1015 is connected to the outside of the positioning hole 1014. A pull block 1016 is connected to the top of the tension spring 1015. A fixing rod 1017 is connected to the inner end of the pull block 1016. A fixing hole 1018 is formed inside the slot 1013. Through the setting of the quick docking assembly 10, when it is necessary to dock the first flange interface 3 with the second flange interface 1001, first rotate the limiting rotating plate 1004 so that it rotates around the pin at the bottom of the first positioning block 1002. At 90°, the side of the limiting rotating plate 1004 abuts against the side wall of the first positioning block 1002, keeping the stretching cylinder 1005 horizontally aligned with the second positioning block 1003. Pulling the pull plate 1011 causes the pull rod 1007 to slide upward along the stretching groove 1006, and the guide block 1008 moves synchronously along the guide groove 1009. The telescopic spring 1010 is further compressed. At the same time, the locking block 1012 at the other end of the pull plate 1011 moves upward to reserve space for the insertion of the second positioning block 1003. The first flange interface 3 is aligned and fitted with the second flange interface 1001, so that the second positioning block 1003 is directly below the locking block 1012. Releasing the pull plate 1011 causes the elastic force of the telescopic spring 1010 to push the pull rod 1007 back to its original position. 1011 moves the locking block 1012 downwards, and the locking block 1012 is guided into the locking groove 1013 by the inclined surface. Its outer side wall fits tightly against the inner side wall of the locking groove 1013, initially completing the mechanical locking of the interface. At this time, the positioning hole 1014 on the pull plate 1011 and the locking block 1012 is aligned with the fixing hole 1018 in the locking groove 1013. Pulling the pull block 1016 upwards stretches the tension spring 1015, and the fixing rod 1017 moves upwards and disengages from the positioning hole 1014. After adjusting the pull block 1016 to align the fixing rod 1017 with the fixing hole 1018, it is released. The rebound force of the tension spring 1015 drives the fixing rod 1017 through the positioning hole 1014. The elastic ball at the bottom of the fixing rod, which is larger than its diameter, is deformed by compression when passing through the fixing hole 1018.After successfully entering the fixing hole 1018, it returns to its original position and locks itself within the fixing hole 1018, achieving secondary locking of the interface. At this time, the pull block 1016 is in contact with the surface of the pull plate 1011. During disassembly, a large pulling force is applied to pull the pull block 1016, the tension spring 1015 is stretched significantly, the fixing rod 1017 moves upward, and the elastic ball at its bottom is deformed again by the pressure of the inner wall of the fixing hole 1018, thus exiting from the fixing hole 1018. Then, the pull plate 1011 is pulled to make the locking block 1012 exit the slot 1013. Finally, the limiting rotating plate 1004 is rotated to 0° to separate the two flange interfaces. The entire process can be completed quickly without tools, and the double locking structure ensures the sealing and stability of the underwater connection.

[0018] Furthermore, the sealing gasket 2 has a thickness of 5mm to 8mm, and the connection between the sealing gasket 2 and the tube bag 1 and the first flange interface 3 is fixed by high-strength adhesive. By setting the sealing gasket 2, its own thickness and elastic deformation can fill the gap between the tube bag 1 and the first flange interface 3. Combined with the fixing effect of the high-strength adhesive, a double sealing structure is formed, which effectively prevents mud from leaking from the interface during underwater filling, and at the same time enhances the integrity of the connection between the tube bag 1 and the flange interface.

[0019] Furthermore, multiple sets of strip-shaped guide holes 4 are evenly distributed on the surface of the tube bag 1, and are detachably connected to the tube bag 1 through the connecting frame. The evenly distributed strip-shaped guide holes 4 ensure that water is evenly discharged from different positions inside the tube bag 1, improving dewatering efficiency. The detachable connection method facilitates individual replacement when the guide holes are blocked or damaged, reducing maintenance costs. At the same time, the number and distribution density of the guide holes can be flexibly adjusted according to the characteristics of the sludge.

[0020] Furthermore, the guide block 1008 and the guide groove 1009 are in clearance fit, and the guide block 1008 can slide along the length direction of the guide groove 1009. By setting the guide block 1008 and the guide groove 1009, the sliding direction of the pull rod 1007 can be precisely limited, avoiding the pull rod from deviating or rotating during movement, ensuring that the pull plate 1011 drives the locking block 1012 to move stably, and improving the reliability of the quick docking assembly 10 operation.

[0021] Furthermore, the telescopic spring 1010 is sleeved on the outside of the pull rod 1007. One end of the telescopic spring 1010 is fixedly connected to the top of the tension cylinder 1005, and the other end is fixedly connected to the bottom side of the pull plate 1011. In its natural state, the telescopic spring 1010 is in a compressed state. Through the setting of the telescopic spring 1010, the elastic potential energy stored in its compressed state can quickly push the pull rod to reset when the pull plate 1011 is released, causing the locking block 1012 to automatically embed into the locking slot 1013, thereby realizing the rapid pre-locking of the interface and reducing underwater operation steps.

[0022] Furthermore, the shape of the locking block 1012 is adapted to the locking groove 1013. After the locking block 1012 is inserted into the locking groove 1013, the outer side wall of the locking block 1012 and the inner side wall of the locking groove 1013 are tightly fitted. Through the setting of the locking block 1012 and the locking groove 1013, a mechanical interlocking structure can be formed. The friction generated by the tightly fitted side walls restricts the relative displacement of the two flange interfaces, providing preliminary radial and axial fixation for the interfaces and laying the foundation for double locking.

[0023] Furthermore, the bottom of the fixing rod 1017 is connected to an elastic ball, and the diameter of the elastic ball is larger than the diameter of the fixing rod 1017. With the setting of the fixing rod 1017, the elastic ball can be locked in the hole after passing through the fixing hole 1018 by its own diameter advantage, forming a secondary locking and enhancing the firmness of the interface connection. At the same time, the deformation characteristics of the elastic ball make it easy to pass through the fixing hole 1018 during installation, and it can be squeezed out by applying a pulling force during disassembly, realizing tool-free quick operation.

[0024] Working principle: During underwater dredging operations, the tube bag 1 is first positioned using a float-type positioning beacon 9 and a traction rope 8. The counterweight 7 at the bottom of the connecting rope 6 balances the buoyancy, ensuring its stable placement in the target water area. When docking with the sludge conveying equipment, the quick docking assembly 10 is activated, rotating the limit plate 1004 to 90°, pulling the pull plate 1011, and causing the pull rod 1007 to slide upwards along the tension groove 1006. The guide block 1008 precisely guides the sludge along the guide groove 1009. At this time, the telescopic spring 1010, made of spring steel, is compressed. Its high elasticity and fatigue resistance allow it to stably store potential energy, ensuring multiple compressions. Even after resetting, it maintains good reset capability. After aligning the first flange interface 3 with the second flange interface 1001, the pull plate 1011 is released. The telescopic spring 1010 releases potential energy due to its excellent elastic deformation capability, quickly pushing the pull rod to reset. This causes the locking block 1012 to embed into the locking groove 1013 along the inclined surface, forming a preliminary lock due to the close fit of the side walls. Subsequently, the pull block 1016 is pulled upwards, causing the tension spring 1015, which is also made of spring steel and has high strength and good ductility, to stretch. It can withstand a large amount of stretching without easily breaking. The fixing rod 1017 moves upwards and aligns with the fixing hole 10. After 18 seconds, the tension spring 1015 rebounds quickly due to its elasticity, causing the fixing rod to pass through the positioning hole 1014. The bottom elastic ball is deformed by compression and then embedded into the fixing hole and resets, completing the secondary locking. At this time, the sealing gasket 2 forms a double seal through elastic deformation and adhesive to prevent mud leakage. During filling, the sludge enters the tube bag 1 through the flange interface. The equally spaced strip-shaped drainage holes 4 drain under the action of the permeable geomembrane 5. The detachable design facilitates maintenance and adjustment. After dredging is completed, pulling the pull block 1016 causes the tension spring 1015 to stretch significantly. Its good toughness ensures that it can withstand large deformations. Without damage, the elastic ball is squeezed out of the fixing hole, and then the pull plate 1011 is pulled to compress the telescopic spring 1010. With its reliable elastic properties, the locking block 1012 is disengaged from the slot 1013. The limiting rotating plate 1004 is rotated to 0° to separate the interface. Throughout the process, the high elasticity, high strength and fatigue resistance of the telescopic spring and tension spring made of spring steel ensure the stable realization of the automatic reset and elastic locking functions, realizes tool-free and quick operation, and ensures the efficiency and stability of underwater operations. This completes the use process of a geotextile tube bag that is easy to fill and dredge underwater.
