Description

Technical Field

[0001] This application relates to the field of salvage devices, and in particular to a cage structure for salvaging water wells. Background Technology

[0002] During the drilling process, various debris such as gravel and waste construction materials often remain inside the well. The presence of debris not only affects the normal function and structural stability of the well, but also easily hinders subsequent equipment installation and may even cause safety hazards. Therefore, it is necessary to remove and clean up any debris in a timely manner during the well drilling process.

[0003] Currently, underwater debris retrieval operations typically involve divers carrying woven nets to dive underwater, collect the debris one by one and put it into the net, and then using hoisting equipment to lift the net containing the debris out of the well.

[0004] Regarding the aforementioned technologies, woven nets are prone to irregular deformation underwater, requiring divers to open the net before loading debris, making underwater operations quite difficult. Furthermore, the woven nets are easily worn or even leaked when subjected to external forces such as sharp edges of debris, affecting salvage operations. Therefore, there is room for improvement. Utility Model Content

[0005] To facilitate the retrieval of underwater debris from wells, this application provides a cage structure for well retrieval.

[0006] This application provides a cage structure for well retrieval, which adopts the following technical solution:

[0007] A cage structure for well retrieval includes a cage-shaped frame and a flexible filter inner liner, both of which have openings at their top ends; the flexible filter inner liner is embedded in the cage-shaped frame and has a plurality of filter holes evenly distributed within it; and two lifting lugs are connected to the top of the cage-shaped frame.

[0008] By adopting the above technical solution, when retrieving debris, the cage structure is connected to the lifting equipment via lifting lugs. The cage frame and flexible filter inner tank are then lowered underwater. Divers place the debris into the flexible filter inner tank, and the lifting equipment raises the cage to the outside of the well. During this process, well water is discharged through the filter holes on the flexible filter inner tank. While underwater, the cage frame limits the flexible filter inner tank, preventing deformation and facilitating better loading of debris. This reduces the difficulty of underwater debris loading and facilitates the retrieval of underwater debris from the well.

[0009] Preferably, the flexible water filter inner tank is composed of a flexible annular portion and a flexible base portion, both of which are made of waste tires; the outer periphery of the flexible base portion overlaps the inner periphery of the bottom end of the flexible annular portion, and the overlap between the flexible base portion and the flexible annular portion is fixed by adhesive.

[0010] By adopting the above technical solution, from an environmental protection perspective, waste car tires are used to manufacture the various components of the flexible water filter inner tank, which effectively reduces the manufacturing cost and achieves effective utilization of waste. At the same time, the flexible water filter inner tank does not need to be molded as a whole, which effectively reduces the manufacturing difficulty of the flexible water filter inner tank. Adhesive is used to bond and fix the flexible ring part and the flexible base part, so as to achieve a stable connection between the flexible ring part and the flexible base part.

[0011] Preferably, the overlap between the flexible base and the flexible annular portion is further connected by a number of bolts and nuts.

[0012] By adopting the above technical solution, the connection strength between the flexible base and the flexible ring is further strengthened by using bolts and nuts, so as to avoid separation between the flexible base and the flexible ring during the subsequent debris retrieval process.

[0013] Preferably, the flexible annular portion is formed by splicing together several flexible plates, and adjacent sides of the flexible plates are connected by several connecting steel wires.

[0014] By adopting the above technical solution, when the flexible water filter inner tank is partially damaged, the corresponding flexible plate can be replaced locally without replacing the entire flexible annular part; at the same time, it is convenient to adjust the size of the flexible annular part according to actual needs.

[0015] Preferably, the lifting lug includes a U-shaped rod, both ends of which are bent to form hooks, and the hooks are hooked to the top of the cage frame.

[0016] By adopting the above technical solution, the hooks formed by bending the ends of the U-shaped rod of the lifting lug are hooked to the top of the cage frame, so that the lifting lug can swing according to actual needs. During the lifting process, it can better adapt to different lifting angles and directions, and improve the flexibility and convenience of the well retrieval cage structure in retrieval operations.

[0017] Preferably, the top of the flexible water filter inner tank is connected to two connecting ears, and the top of each connecting ear extends out of the top of the flexible water filter inner tank.

[0018] By adopting the above technical solution, and by setting the connecting ear at the top of the flexible water filter inner tank, when it is necessary to separate the flexible water filter inner tank from the cage frame in the future, the flexible water filter inner tank can be lifted out of the cage frame through the connecting ear.

[0019] Preferably, the connecting lug is fixed to the flexible filter inner tank by a number of bolts and nuts.

[0020] By adopting the above technical solution, a stable connection between the connecting ear and the flexible water filter inner tank is achieved, preventing the connecting ear from detaching from the flexible water filter inner tank.

[0021] Preferably, the connecting ear passes through the holes in the cage frame to the outside of the cage frame and extends out of the top of the cage frame.

[0022] By adopting the above technical solution, the flexible water filter inner tank is secured and limited by the connecting ear, which helps to ensure that the flexible water filter inner tank is stably installed on the cage frame and prevents the flexible water filter inner tank from detaching from the cage frame.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The flexible filter liner is reinforced and limited by a cage-shaped frame. When filling the liner with debris underwater, the cage-shaped frame can restrict the deformation of the flexible filter liner, so that the flexible filter liner can be better filled with debris.

[0025] 2. With the connecting ear at the top of the flexible water filter inner tank, when separating the flexible water filter inner tank from the cage frame, the flexible water filter inner tank can be lifted out of the cage frame through the connecting ear.

[0026] 3. By having the connecting ears pass through the outside of the cage frame and extend to the top of the cage frame, the connecting ears are used to lock and limit the cage frame, which helps to make the flexible water filter inner tank more securely installed in the cage frame.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a cage structure for well retrieval, referring to... Figure 1 and Figure 2 The system includes a cage-shaped frame 1 and a flexible filter inner tank 2. The top of the cage-shaped frame 1 is symmetrically connected with two lifting lugs for connecting lifting equipment during use. The top of the flexible filter inner tank 2 is open, and the flexible filter inner tank 2 is embedded in the cage-shaped frame 1. The flexible filter inner tank 2 has a number of filter holes evenly distributed.

[0035] In this embodiment, both the cage frame 1 and the flexible filter inner tank 2 are hemispherical. The cage frame 1 is assembled and welded from steel reinforcement segments; in other embodiments, it can also be made of stainless steel pipes or galvanized steel pipes. The surface of the cage frame 1 is coated with an anti-rust paint layer to prevent corrosion.

[0036] The lifting lug includes a U-shaped rod 4, with both ends of the U-shaped rod 4 bent to form hook parts 41. Both hook parts 41 of the U-shaped rod 4 are hooked to the top of the cage frame 1, achieving a stable connection between the U-shaped rod 4 and the cage frame 1. When the cage structure body is subsequently lifted by lifting equipment, the U-shaped rod 4 can be hooked to the hook of the lifting equipment to facilitate the stable lifting and placement of the cage structure. Simultaneously, the U-shaped rod 4 can swing to different angles as needed, which improves the overall applicability of the lifting lug.

[0037] Reference Figure 3 and Figure 4 The flexible filter inner tank 2 is composed of a flexible annular portion 21 and a flexible base portion 22. The flexible annular portion 21 is made of several flexible plates spliced ​​together, and adjacent flexible plates are connected by several connecting steel wires on their adjacent sides. Specifically, the two ends of the connecting steel wires pass through the outer side of the two flexible plates to the inner side, and the ends of the connecting steel wires are bent and abut against the inner side of the flexible plates. In actual use, the splicing points of adjacent flexible plates can be further reinforced with glue.

[0038] The bottom outer periphery of the flexible base portion 22 overlaps with the bottom inner periphery of the flexible annular portion 21, and the overlap of the flexible annular portion 21 and the flexible base portion 22 is fixed by adhesive. At the same time, the flexible annular portion 21 and the flexible base portion 22 are also connected by bolts and nuts to achieve a stable connection between the flexible annular portion 21 and the flexible base portion 22, effectively preventing the flexible annular portion 21 and the flexible base portion 22 from separating during subsequent actual use.

[0039] In this embodiment, both the flexible plate of the flexible annular portion 21 and the flexible base portion 22 are made from waste tires. From an environmental protection perspective, this helps to reduce the overall manufacturing cost of the cage structure and achieve effective utilization of waste.

[0040] Reference Figure 1 and Figure 2 The flexible filter inner tank 2 has two connecting ears 3 at its top, which extend beyond the top of the flexible annular portion 21. Each connecting ear 3 has a hook-and-loop hole. The connecting ears 3 are made from cut waste tires. The bottom of the connecting ears 3 is fixed to the flexible filter inner tank 2 with several bolts and nuts to achieve a stable connection. When separating the flexible filter inner tank 2 from the cage frame 1, the flexible filter inner tank 2 can be lifted out of the cage frame 1 through the two connecting ears 3, facilitating the assembly and disassembly of the flexible filter inner tank 2.

[0041] Reference Figure 1 and Figure 2 Several reinforcing steel wires 5 are also provided at the connection between the connecting ear 3 and the flexible ring part 21. Both ends of the reinforcing steel wires 5 pass through the connecting ear 3 and the flexible ring part 21 from the side of the connecting ear 3 away from the flexible ring part 21. Both ends of the reinforcing steel wires 5 are bent and abut against the inner side of the flexible ring part 21, which further improves the connection stability between the connecting ear 3 and the flexible ring part 21.

[0042] Reference Figure 1 and Figure 2 The connecting ears 3 are all inserted through the holes in the cage-shaped frame 1 to the outside of the cage-shaped frame 1 and extend beyond the top of the cage-shaped frame 1. These two connecting ears 3 are used to engage and limit the flexible filter inner liner 2, preventing it from separating from the cage-shaped frame 1 during subsequent retrieval, thus ensuring the seamless connection between the flexible filter inner liner 2 and the cage-shaped frame 1. In other embodiments, several iron clamps can be placed at the top edges of both the flexible filter inner liner 2 and the cage-shaped frame 1 to clamp and fix the top edge areas of both, further preventing the flexible filter inner liner 2 from detaching from the cage-shaped frame 1 during retrieval.

[0043] The implementation principle of this embodiment is as follows: During the salvage operation, the cage structure is connected to the hoisting equipment via lifting lugs. The hoisting equipment then lowers the entire cage structure into the well. Divers place debris into the flexible filter inner tank 2 underwater. The hoisting equipment then lifts the cage structure out of the well. During this process, well water is discharged through the filter holes on the flexible filter inner tank 2. When loading debris underwater, the cage frame 1 can restrict deformation of the flexible filter inner tank 2, effectively reducing the difficulty for divers to load debris underwater and ensuring the smooth progress of the well drilling project.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
