[0002] In the field of geological engineering, especially in geological exploration and brine mining operations in salt lake areas, drilling water stopping is a key technical link. Due to the presence of multiple brine-bearing layers underground during geological drilling or brine mining in salt lake areas, if effective water stopping is not implemented, brine from different layers will cross-contaminate and become contaminated, seriously affecting the accuracy of brine sampling and the reliability of hydrological observation data, thereby hindering subsequent resource development and geological research.

[0010] Preferably, the external load-bearing object connecting ring is connected to the counterweight.

[0011] Preferably, the resistance spike is an iron spike, which is welded to the top of the support rod, and the support rod is hinged to the middle tube through a support rod connector.

[0015] Preferably, the device is suitable for drilling holes with a diameter of less than 100 cm in salt lake areas, and can separate and stop water in the brine layer by filling clay balls.

[0016] Working principle: When the device is in use, it is first folded up. According to the position of water-stopping required, the depth of the waterproof layer is calculated in advance to determine the length of the load-bearing traction rope and the operating line. After that, the device can be submerged along the constructed well wall to the position of the waterproof layer, so as to better enable the device to dive to the specified position. After determining that the device has reached the specified depth, first place a steel bar larger than the wellhead diameter on the wellhead, and fix the load-bearing traction rope on the steel bar. The resistance spike increases the friction between the device and the well wall, which helps the device to be more firmly stuck on the well wall at the specified position. Finally, sufficient clay balls can be thrown into the well from the wellhead. After the clay balls swell when they come into contact with water, the upper and lower brine-containing layers can be separated to achieve the water-stopping effect.

[0017] The present invention provides a simple auxiliary water-stopping device with the following beneficial effects: 1. The present invention is made of common and simple materials such as steel bars, steel pipes, and iron wires. These materials are low-cost and easy to obtain, which greatly reduces the production cost of the device. In addition, its production process is simple and does not require complicated processing procedures, saving a lot of manpower, material resources and time costs, and improving production efficiency.

[0018] 2. During the actual operation of the present invention, it is only necessary to calculate the length of the load-bearing traction rope and the operating line according to the water-stop position, and then manually lower the device to the corresponding depth. The operating line can be pulled to open the device and make it stuck on the well wall. Finally, clay balls, dry kelp and other water-stopping materials are put in to complete the water-stopping work. The whole operation process is simple and easy to understand and easy to control. No professional and complex skill training is required. Ordinary operators can quickly get started, which reduces the difficulty of operation and labor costs.

[0019] 3. The present invention is suitable for boreholes with a diameter of less than 100 cm in salt lake areas. Whether in boreholes with a smaller diameter or in boreholes close to the upper limit of 100 cm in diameter, it can achieve a stable water-stopping effect through its adjustable and adaptable structure, the movable connection between the long bones, short bones and the middle tube, and the flexible adaptation of the support net, thereby expanding its scope of application in geological engineering in salt lake areas.

The materials used are all common metals, which will not release harmful substances in the special environment of the salt lake area. Furthermore, the water stoppers, such as clay balls, are made of natural materials and will not pollute the groundwater or surrounding soil after swelling when exposed to water. This meets environmental requirements and is conducive to sustainable geological engineering operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see the attached Figure 1 -Attached Figure 3 , the embodiment of the present invention provides a simple auxiliary water-stopping device, comprising: a protective cover 3, a connecting line 4, a middle tube 5 and a support rod 9; The inside of the protective cover 3 is connected with the operating wire 2; One end of the connecting line 4 is fixed with a middle tube 5, and the other end is connected to a load-bearing traction rope 1. The upper outer wall of the traction rope 1 is provided with a steel bar body 301; A pulley 6 is fixedly connected to the middle tube 5. A long bone connector 10 and a short bone connector 11 are sleeved on the lower outer wall of the middle tube 5. A second spring 12 is provided between the long bone connector 10 and the short bone connector 11. An external load-bearing connecting ring 16 is fixedly connected to the bottom of the middle tube 5. The short bone connector 11 and the long bone connector 10 are connected to the short bone 13 and the long bone 14 respectively. The operating wire 2 passes through the pulley 6 and is connected to the clamp 7; The top of the support rod 9 is fixedly connected to the resistance spike 8, and one end is connected to the support rod connector 15. The support rod connector 15 is fixedly connected to the bottom of the middle tube 5. The support rod 9 is connected to the middle tube 5 through the support rod connector 15 and is connected to the support net 17; The long bones 14 and the short bones 13 are connected to the middle tube 5 through the long bone connector 10 and the short bone connector 11 respectively, and are connected to the support net 17. The upper surface of the support net 17 is provided with clay balls 302.

[0025] Specifically, when the device is used, it is first folded up, and the depth of the waterproof layer is calculated in advance according to the location of the water stop required to determine the length of the load-bearing traction rope 1 and the operating line 2. After that, the device can be submerged to the waterproof layer along the well wall that has been constructed. If the device has a large submergence resistance, a certain weight of iron blocks, plumb bobs, etc. can be connected to the external load-bearing object connecting ring 16 at the bottom of the device to better enable the device to dive to the specified position. After determining that the device has reached the specified depth, the steel body 301 larger than the wellhead diameter is first used. Place it on the wellhead, and fix the load-bearing traction rope 1 on the steel bar body 301 to ensure that the device is suspended at the corresponding depth position. Then pull the operating line 2 to open the device and get it stuck at the depth. The resistance spike 8 increases the friction between the device and the well wall, which helps the device to be more firmly stuck on the well wall at the specified position. Finally, sufficient clay balls 302, dry kelp and other plugging materials can be thrown into the well from the wellhead. After the clay balls 302, dry kelp and other plugging materials swell when exposed to water, the upper and lower brine-containing layers can be separated to achieve a water-stopping effect.

[0026] Please see the attached Figure 1 , the load-bearing traction rope 1 and the operating line 2 are made of steel wire rope; the middle tube 5 is a steel pipe, a window is provided on its upper portion, the support net 17 is interwoven by iron chains, and the support rod 9 is made of steel bars.

[0027] Specifically, the steel wire rope has the characteristics of high strength, wear resistance and corrosion resistance. It can stably withstand the gravity traction during the lowering process of the device and the tension during operation, ensuring the position control accuracy and structural stability of the device in the borehole. The support net 17 is woven from iron chains. The flexible connection characteristics of the iron chains enable it to flexibly adapt to the shape of the inner wall of the borehole. At the same time, it has high-strength load-bearing capacity and can evenly carry and distribute sealing materials such as clay balls 302, effectively preventing the scattering and displacement of sealing materials during the filling process, and providing reliable carrier support for the separation and water stopping of the halide layer. The support rod 9 is made of steel bar material, and the high rigidity and bending resistance of the steel bar are used to form a stable support structure when the device is unfolded. The resistance spike 8 welded on the top can firmly abut the borehole wall through the rigid support of the support rod 9, significantly increasing the friction between the device and the well wall, ensuring that the device remains in a fixed position during the filling of the water-stopping material, and improving the reliability and stability of the water-stopping operation.

[0028] Please see the attached Figure 1 The clamping head 7 includes a triangular tip, an iron sheet 1 701, an iron sheet 2 702, a first spring 703 and an iron plate 704. The iron plate 704 is fixed to the inner wall of the middle tube 5. The triangular tip of the clamping head 7 is retracted through the window of the middle tube 5.

[0029] Specifically, the clamping head 7 is a 2mm thick iron sheet, one end of which extends outward is a triangular pointed head, and the other end is fixed with an iron sheet 701 with a diameter of 10mm and a thickness of 2mm. A circular ring with a diameter of 5mm is welded on the other side of the iron sheet 701 to connect the operating wire 2 and fix the first spring 703 on the iron sheet 701; the iron sheet 702 is a square iron sheet with a length and width of 10mm and a thickness of 2mm, and its bottom is fixed on the iron plate 704; the iron plate 704 is made of an iron plate with a diameter of 26mm and a thickness of 5mm. It is fixed on the inner wall of the middle tube 5 to provide support for the iron sheet 701, the iron sheet 702 and the first spring 703.

[0030] Please see the attached Figure 1 , the external load-bearing connecting ring 16 is connected to the counterweight; the resistance thorn head 8 is an iron spike, welded to the top of the strut 9, and the strut 9 is hinged to the middle tube 5 through the strut connector 15.

[0031] Specifically, the resistance spike 8 is made of iron and is fixed on the top of the support rod 9. Its main function is to get stuck on the inner wall of the borehole after the device is opened to increase the resistance. The support rod 9 is a steel bar with a diameter of 5 mm and a length of 50 cm. Its main function is to open the support net 17 after the device is opened. The support rod 9 is hinged to the middle tube 5 with the help of the support rod connector 15. The support rod 9 can rotate with the connection point with the middle tube 5 as the axis. When the device is deployed in the borehole, the support rod 9 can open outward, driving the resistance spike 8 to abut the borehole wall.

[0032] Please see the attached Figure 1 The support rod 9 is a steel bar with a diameter of 5mm and a length of 50cm. The support net 17 is interwoven with a 3mm iron chain. The long bone 14 and the short bone 13 are steel bars with a diameter of 3mm, and are movably connected to the middle tube 5 through the long bone connector 10 and the short bone connector 11.

[0033] Specifically, the support net 17 is made of iron chains with a diameter of 3 mm. The iron chains have good flexibility and high strength. The mesh structure formed by the interweaving can not only disperse the pressure evenly, but when the device is unfolded, the long bones 14 and the short bones 13 cooperate with the support rods 9 to support the support net 17, thereby expanding the coverage of the device, ensuring that the sealing material can be filled into a larger area, and improving the efficiency and effect of water stopping. When the device needs to be removed from the drilled hole, the long bones 14 and the short bones 13 can be retracted inward to reduce the overall volume of the device, making it easier to remove it.

[0034] Please see the attached Figure 1 The outer diameter of the middle tube 5 is 30 mm, the wall thickness is 2 mm, and the window size is 10 mm long and 2.5 mm wide; the triangular tip of the clamp 7 is 2 mm thick, and the first spring 703 is fixed between the iron sheet 701 and the iron plate 704; the pulley 6 is a steel pulley with a diameter of 10 mm, and the connecting line 4 uses a steel bar with a diameter of 5 mm.

[0035] Specifically, the outer diameter of the middle tube 5 is 30 mm and the wall thickness is 2 mm, so that the middle tube 5 has both appropriate strength and internal space, which facilitates the smooth lowering and operation of the entire device in the borehole. The first spring 703 is firmly fixed between the iron sheet 1 701 and the iron plate 704. When the triangular tip is extended and stuck into the well wall, the first spring 703 is compressed to store elastic potential energy; when the triangular tip needs to be retracted, the first spring 703 releases elastic potential energy, prompting the triangular tip to retract quickly and accurately into the middle tube 5.

[0036] Please see the attached Figure 1 -Attached Figure 3 The device is suitable for drilling holes with a diameter of less than 100 cm in salt lake areas, and can separate and stop the brine layer by filling it with clay balls 302.

[0037] Specifically, the device is designed for the special geological conditions of the salt lake area and is suitable for drilling projects with a borehole diameter of less than 100 cm. It can efficiently achieve the separation and water stopping of the brine-containing layer. The groundwater in the salt lake area has a high salt content and is highly corrosive. The brine-containing layers at different depths in the borehole are prone to form string layers due to pressure differences, resulting in brine mixing or reduced mining efficiency. The device is precisely adapted to the structural design of small and medium apertures, and uses the coordinated control of the load-bearing traction rope and the operating line 2. It can be flexibly lowered to the target depth, and mechanically fixed to the well wall through the clamping head 7, the resistance spike 8, and the well wall to ensure the stable positioning of the device during the filling process.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
