Description

Technical Field

[0001] This invention relates to the field of hydrogeological exploration technology, specifically to an easily detachable hydrogeological exploration borehole water inrush sealing device. Background Technology

[0002] Hydrogeological exploration is an applied geological discipline that studies the distribution, formation, and movement of groundwater in rock and soil masses and its interaction with the natural environment and human activities. Its main purpose is to identify the hydrogeological conditions of a specific area and provide a scientific basis for water resource development and utilization, engineering construction, and environmental protection. Hydrogeological drilling can directly reveal the stratigraphic features and collect rock, soil, and water samples. For hydrogeological exploration boreholes that require periodic sampling, the boreholes can be temporarily sealed after sampling is completed.

[0003] In the existing technology, water inrush sealing devices can temporarily seal exploration boreholes. However, due to their structural limitations, the sealing effect is poor when used for exploration boreholes with irregular channels. Not only can they not effectively seal the exploration boreholes, but they are also prone to causing the exploration boreholes to collapse. At the same time, they are difficult to disassemble, which reduces the efficiency of hydrogeological exploration.

[0004] Therefore, those skilled in the art need a water inrush sealing device that can better adapt to the shape of the exploration borehole and is easy to disassemble in order to overcome the above problems. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention proposes an easily disassembled hydrogeological exploration borehole water inrush sealing device. To solve the technical defects of experimental equipment being difficult to use for sealing irregularly shaped exploration boreholes and difficult to disassemble, this invention creatively incorporates a transmission component and a sealing component. The multiple extended sections of the sealing component can form a complete sealing structure. Even if the borehole diameter is irregular, the multiple sections of the sealing component, by extending at different lengths and abutting against the borehole radially, allow the sealing component to quickly adapt to the inner wall of the borehole and achieve excellent sealing and protection effects.

[0006] The technical solution adopted in this invention is as follows:

[0007] According to an embodiment of the present invention, an easily detachable hydrogeological exploration borehole water inrush sealing device includes a fixing component, a sealing component, and a transmission component. The fixing component is hinged to the upper part of the transmission component, and the transmission component is movably inserted into the sealing component. When sealing an exploration borehole with an irregular diameter, the technician can control the transmission component to squeeze the sealing component, causing multiple parts of the sealing component to extend to different lengths and abut against the inner wall of the exploration borehole.

[0008] According to the water inrush sealing device of the present invention, the multiple extended parts of the sealing component can form a complete sealing structure. Even if the diameter of the exploration hole is irregular, the multiple parts of the sealing component can extend to different lengths and abut against the exploration hole in the radial direction, so that the sealing component can quickly adapt to the inner wall of the exploration hole and has a good sealing and protection effect.

[0009] According to some embodiments of the present invention, the fixing assembly includes a fixing plate, the transmission assembly includes a transmission shaft, a support platform, a positioning post, and a transmission component. The edge of the fixing plate is provided with a plurality of fixing feet arranged circumferentially at intervals. A through fixing hole is formed in the center of the fixing plate. The transmission shaft passes through the fixing hole and is threaded to the inner wall of the fixing hole. The support platform is fixedly connected to the lower part of the transmission shaft. The edge of the support platform is formed with a support flange in the direction away from the fixing plate. The positioning post is fixedly connected to the center of the bottom wall of the support platform. There are multiple transmission components that surround the positioning post and are retractably connected to the bottom wall of the support platform.

[0010] According to some embodiments of the present invention, the transmission assembly includes a support housing and a first elastic element. The outer wall of the support flange forms a limiting protrusion. The support housing is connected to the fixing plate and movably sleeved on the outside of the support platform. The inner wall of the support housing has a limiting recess that cooperates with the limiting protrusion. The upper end of the transmission element is connected to the bottom wall of the support platform through the first elastic element.

[0011] According to some embodiments of the present invention, the sealing assembly includes a sealing ring, connecting posts, and sealing members. The sealing ring is connected to the bottom wall of the supporting housing through a plurality of connecting posts. The sealing ring is arranged around the outside of a plurality of transmission members. A plurality of circumferentially spaced through-holes are formed on the side wall of the sealing ring, and the through-holes correspond one-to-one with the transmission members. There are a plurality of sealing members, each passing through one of the through-holes. One end of the sealing member near the center of the sealing ring abuts against the side wall of the transmission member.

[0012] According to some embodiments of the present invention, the sealing member includes a sealing plug, a sealing shaft, a fitting portion, and a second elastic member. The sealing shaft is connected between the sealing plug and the fitting portion. The sealing plug converges in a direction away from the sealing shaft. The radius of the arc of the outer contour of the transmission member gradually decreases from top to bottom. The surface of the fitting portion adjacent to the transmission member is a concave arc surface and fits the transmission member. The second elastic member is sleeved on the outside of the sealing shaft and abuts against the fitting portion and the sealing ring.

[0013] According to some embodiments of the present invention, the sealing assembly includes a traction member and an airbag. The traction member is telescopically connected between adjacent sealing shafts and located outside the sealing ring. The sealing ring has a plurality of air vents spaced apart between adjacent communication ports. The support housing has a plurality of vent holes corresponding one-to-one with the air vents. One end of the airbag surrounds the traction member, the airbag passes through the air vent, and the other end seals the vent hole.

[0014] According to some embodiments of the present invention, the traction member includes a traction ear, a connecting ring, and a telescopic shaft. A traction protrusion extending in a circumferential direction is formed on the side wall of the sealing shaft adjacent to the sealing plug. The outer wall of the traction ear is fixedly connected to the traction protrusion. The connecting ring is formed at both ends of the telescopic shaft and the connecting ring is connected to the traction ear.

[0015] According to some optional embodiments of the present invention, the elastic coefficient of the first elastic element is greater than the elastic coefficient of the second elastic element.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] (1) The multiple parts of the plugging component can form a complete plugging structure. Even if the diameter of the exploration hole is irregular, the multiple parts of the plugging component can extend to different lengths and abut against the exploration hole in the radial direction, so that the plugging component can quickly adapt to the inner wall of the exploration hole and has a good plugging and protection effect.

[0018] (2) When the technician rotates the transmission shaft downwards in a spiral motion, the support platform follows and descends, causing the positioning column to also descend. The positioning column can provide the center positioning function for other components of the sealing device, preventing other components from interfering and getting stuck, thus improving the reliability of the sealing device. The transmission component can squeeze the sealing assembly, realizing the transmission from the technician rotating the transmission shaft to the radial outward movement of the sealing assembly.

[0019] (3) The cooperation of the limiting protrusion and the limiting recess can ensure that the support platform moves in the vertical direction and remains relatively fixed to the fixed plate in the circumferential direction, thereby improving the structural stability of the sealing device.

[0020] (4) When the transmission component moves downward, the transmission component can squeeze the sealing component to move outward in the radial direction. The sealing component that contacts the inner wall of the exploration hole is embedded in the soil layer and remains fixed, so that the transmission component connected to it remains fixed and compresses the corresponding first elastic component.

[0021] (5) The fitting part is squeezed and drives the sealing shaft and sealing plug to move in the radial outward direction. After the sealing plug is inserted into the soil and fixed, it applies a large resistance to the transmission component, so that the transmission component remains fixed and compresses the corresponding first elastic element. The second elastic element is sleeved on the outside of the sealing shaft and abuts between the fitting part and the sealing ring. The second elastic element is compressed when the sealing shaft and sealing plug move in the radial outward direction, which can provide the sealing shaft and sealing plug with the power to restore the position.

[0022] (6) The airbag can fully seal the gap between adjacent sealing shafts, especially the gap between the sealing ring and the hole wall of the exploration hole, thereby improving the sealing effect of the water inrush sealing device.

[0023] Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] refer to Figure 1-Figure 5According to an embodiment of the present invention, a detachable water inrush sealing device for hydrogeological exploration boreholes includes a fixing component 1, a sealing component 2, and a transmission component 3. The fixing component 1 is hinged to the upper part of the transmission component 3. The fixing component 1 serves to fix the water inrush sealing device at the exploration borehole and also facilitates sealing and protection of the exploration borehole. The transmission component 3 is movably inserted into the sealing component 2. When sealing exploration boreholes with irregular diameters, technicians can control the transmission component 3 to compress the sealing component 2, causing multiple parts of the sealing component 2 to extend out at different angles. The length of the sealing component 2 is pressed against the inner wall of the borehole. Technicians compress the sealing component 2 so that it can adapt to the inner wall of the borehole and unfold into a complete structure for blocking water flow within the borehole. During the compression of the sealing component 2, multiple parts of the sealing component 2 can first extend radially outward at the same rate. The parts that first contact the inner wall of the borehole can be embedded in the soil to play a role in sealing and fixing. The other parts continue to extend outward until the entire structure is embedded in the soil, thereby achieving adaptation to the shape of the inner wall of the borehole.

[0040] According to the water inrush sealing device of the present invention, the multiple extended parts of the sealing component 2 can form a complete sealing structure. Even if the diameter of the exploration hole is irregular, the multiple parts of the sealing component 2 can extend to different lengths and abut against the exploration hole in the radial direction, so that the sealing component 2 can quickly adapt to the inner wall of the exploration hole and has a good sealing and protection effect.

[0041] refer to Figure 1-Figure 5According to some embodiments of the present invention, the fixing component 1 includes a fixing plate 11, and the transmission component 3 includes a transmission shaft 31, a support platform 32, a positioning post 33, and a transmission component 34. The edge of the fixing plate 11 is provided with a plurality of circumferentially spaced fixing feet 12. The fixing plate 11 is used to fix itself at the entrance of the exploration hole. The fixing feet 12 can further improve the fixing strength of the fixing plate 11. A through fixing hole 13 is formed in the center of the fixing plate 11. The transmission shaft 31 passes through the fixing hole 13 and is threadedly connected to the inner wall of the fixing hole 13. A technician can squeeze the sealing component 2 by rotating the transmission shaft 31. The support platform 32 is fixed below the transmission shaft 31 and extends into the exploration hole. It is the frame structure of the water inrush sealing device, used to connect and support the transmission component 3 and the sealing component 2. The edge of the support platform 32 faces away from the fixing plate 11. The direction is formed by the support flange 321, and the positioning column 33 is fixed to the center of the bottom wall of the support platform 32. When the technician rotates the transmission shaft 31 and moves downward in a spiral, the support platform 32 follows and descends, so that the positioning column 33 also descends. The positioning column 33 can provide the center positioning function for other components of the water inrush sealing device, prevent other components from interfering and getting stuck, and improve the reliability of the water inrush sealing device. There are multiple transmission components 34 that surround the positioning column 33 and are telescopically connected to the bottom wall of the support platform 32. The transmission components 34 can squeeze the sealing component 2, realizing the transmission from the technician rotating the transmission shaft 31 to the radial outward movement of the sealing component 2. For example, the transmission component 34 can be multiple concentric wedge-shaped frustums surrounding the positioning column 33, and the size of the transmission component 34 decreases from top to bottom. Multiple transmission components 34 can form a complete frustum.

[0042] refer to Figure 3 and Figure 4According to some embodiments of the present invention, the transmission assembly 3 includes a support housing 35 and a first elastic member 36. A limiting protrusion 3211 is formed on the outer wall of the support flange 321. The support housing 35 is connected to the fixing plate 11 and movably sleeved on the outside of the support platform 32. The support housing 35 is a frame structure of the water inrush sealing device, serving to accommodate and support other components. A limiting recess 351 is formed on the inner wall of the support housing 35, which cooperates with the limiting protrusion 3211. The cooperation between the limiting protrusion 3211 and the limiting recess 351 ensures that the support platform 32 can move vertically and circumferentially. The upward-facing component remains relatively fixed to the fixed plate 11, thereby improving the structural stability of the water inrush sealing device. The upper end of the transmission component 34 is connected to the bottom wall of the support platform 32 through the first elastic element 36, which enables the extension and retraction of the transmission component 34. In particular, when the part of the sealing component 2 that contacts one of the transmission components 34 is embedded with the exploration hole, and the other parts of the structure continue to extend, the transmission component 34 that cooperates with it can be fixed by the compression of the first elastic element 36 when the support platform 32 continues to descend, while the other transmission components 34 can continue to follow the support platform 32 to descend. For example, the first elastic element 36 is a spring.

[0043] In one embodiment of the present invention, a drive shaft 31 bearing is provided in the middle of the drive shaft 31. When the technician rotates the upper part of the drive shaft 31 in a spiral direction, the lower part of the drive shaft 31 can be fixed in the circumferential direction and move up and down. The support housing 35 and the fixing plate 11 are connected by a vent column 37 to achieve fixation. The fixing plate 11 has a plurality of vent ports 111 that correspond one-to-one with the vent columns 37 and can be opened and closed. The technician can inflate the vent columns 37 by connecting an external air pump to the vent ports 111.

[0044] refer to Figures 2-8 According to some embodiments of the present invention, the sealing assembly 2 includes a sealing ring 21, connecting posts 22, and sealing members 23. The sealing ring 21 is connected to the bottom wall of the support housing 35 through multiple connecting posts 22. The sealing ring 21 is arranged around the outside of multiple transmission members 34. Multiple circumferentially spaced through-holes 211 are formed on the side wall of the sealing ring 21, and the through-holes 211 correspond one-to-one with the transmission members 34. There are multiple sealing members 23, which are respectively inserted into the through-holes 211. The end of the sealing member 23 near the center of the sealing ring 21 abuts against... On the side wall of the transmission component 34, the sealing ring 21 is the frame structure of the sealing assembly 2, which has the function of supporting and accommodating other components. The surface of the sealing component 23 adjacent to the transmission component 34 can be an arc-shaped surface, so that the sealing component 23 and the surface of the transmission component 34 are fully in contact. When the transmission component 34 moves downward, the transmission component 34 can squeeze the sealing component 23 to move outward in the radial direction. The sealing component 23 that contacts the inner wall of the exploration hole is embedded in the soil layer and kept fixed, so that the transmission component 34 connected to it is kept fixed and the corresponding first elastic element 36 is compressed.

[0045] refer to Figure 6 According to some embodiments of the present invention, the sealing member 23 includes a sealing plug 231, a sealing shaft 232, a fitting part 233, and a second elastic member 234. The sealing shaft 232 is connected between the sealing plug 231 and the fitting part 233. The sealing shaft 232 can support other components of the sealing assembly 2, ensuring that the sealing assembly 2 can be smoothly deployed in the exploration hole. The sealing plug 231 is tapered away from the sealing shaft 232, which facilitates the insertion of the end of the sealing plug 231 into the hole wall of the exploration hole, thereby improving the sealing effect of the water inrush sealing device. The radius of the arc of the outer contour of the transmission member 34 gradually decreases from top to bottom. The surface of the fitting part 233 adjacent to the transmission member 34 is a concave arc surface and fits the transmission member 34, so that when the transmission member 34 moves from top to bottom, the fitting part 233 is squeezed and drives the sealing shaft 232 and the sealing member 234. The plug 231 moves radially outward and applies significant resistance to the transmission member 34 after it is inserted into the soil and fixed, keeping the transmission member 34 fixed and compressing the corresponding first elastic member 36. The second elastic member 234 is sleeved on the outside of the sealing shaft 232 and abuts between the fitting part 233 and the sealing ring 21. The second elastic member 234 is compressed when the sealing shaft 232 and the sealing plug 231 move radially outward, providing the sealing shaft 232 and the sealing plug 231 with the power to return to their original positions. For example, when the water inrush sealing device is removed from the exploration hole, as the first elastic member 36 returns to its original position, the pressure of the transmission member 34 on the fitting part 233 decreases and the position of the transmission member 34 gradually rises, allowing the second elastic member 234 to return to its original position and drive the other parts of the sealing member 23 to move radially inward.

[0046] refer to Figures 2-8According to some embodiments of the present invention, the sealing assembly 2 includes a traction member 24 and an airbag. The traction member 24 is telescopically connected between adjacent sealing shafts 232 and located outside the sealing ring 21. The sealing ring 21 has a plurality of air vents 212 spaced apart between adjacent communication ports. The support housing 35 has a plurality of vent holes 352 corresponding one-to-one with the air vents 212. One end of the airbag surrounds the traction member 24, the airbag passes through the air vent 212, and the other end seals the vent hole 352. When the sealing shaft 232 moves radially outward, the traction member 24 stretches the airbag. This allows the airbag to fully seal the gap between adjacent sealing shafts 232, especially the gap between the sealing ring 21 and the hole wall of the exploration hole, thereby improving the sealing effect of the water inrush sealing device. The other end of the airbag can extend along the surface of the transmission component 34 from bottom to top and seal the vent hole 352, so that the inner cavity of the airbag is sealed and connected to the inner cavity of the vent hole 352, thereby sealing and connecting the inner cavity of the ventilation column 37 to the inner cavity of the airbag. Technicians can inflate the airbag by connecting an external air pump to the vent 111, or deflate the airbag by opening the vent 111.

[0047] refer to Figure 6 and Figure 8 According to some embodiments of the present invention, the traction member 24 includes a traction ear 241, a connecting ring 242, and a telescopic shaft 243. A traction protrusion 2321 extending in the circumferential direction is formed on the side wall of the sealing shaft 232 adjacent to the sealing plug 231. The outer wall of the traction ear 241 is fixedly connected to the traction protrusion 2321. Connecting rings 242 are formed at both ends of the telescopic shaft 243 and the connecting rings 242 are connected to the traction ear 241. The extension and retraction of the telescopic shaft 243 facilitates the traction member 24 to adapt to the dynamic distance between adjacent sealing shafts 232 in the moving state, ensuring that the traction member 24 can stably support one end of the airbag and improve the reliability of the water inrush sealing device.

[0048] refer to Figure 3 , Figure 6 and Figure 8 According to some optional embodiments of the present invention, the elastic coefficient of the first elastic member 36 is greater than that of the second elastic member 234, such that when the transmission member 34 moves downward and presses the fitting part 233, the second elastic member 234 is compressed first, ensuring that the end of the plug 231 is inserted into the hole wall of the exploration hole, thereby improving the structural rationality of the water inrush plugging device.

[0049] The following describes the specific method of using the water inrush sealing device according to the present invention. After the survey is completed, the technician uses the water inrush sealing device to seal the survey hole. First, the sealing component 2 and the transmission component 3 are placed into the survey hole, and the fixing plate 11 is fixed to the ground using the fixing foot 12. Then, the technician rotates the transmission shaft 31 to drive the transmission shaft 31 down, causing the transmission component 34 to move downward. During the movement, the transmission component 34 squeezes the fitting part 233 and drives the fitting part 233 to move radially outward. At this time, the second elastic element 234 is compressed, and the fitting part 233 can drive the sealing component 23 as a whole to move radially outward. The sealing plug 231 that contacts the inner wall of the survey hole is inserted into the soil layer and fixed. The transmission component 34 that cooperates with it also remains fixed. At this time, the corresponding first elastic element 36 is compressed, and the remaining transmission components 34 continue to move downward, and the other fitting parts 233 continue to move downward. Move radially outward until all the plug plugs 231 are inserted into the soil and fixed. At this point, all the plugging parts 23 and the transmission parts 34 are fixed. The technician stops rotating the transmission shaft 31 and inflates the airbag by connecting an external air pump to the vent 111, causing the airbag to expand and seal the exploration hole. Then, the vent 111 is closed to complete the installation of the water inrush sealing device. When disassembling the water inrush sealing device, the technician opens the vent 111 to deflate the airbag. Then, the transmission shaft 31 is rotated in the opposite direction to restore the first elastic element 36 and allow the transmission part 34 to move upward. As the pressure of the transmission part 34 on the mating part 233 decreases, the second elastic element 234 restores and drives the entire plugging part 23 to move radially inward, causing the plugging assembly 2 to detach from the hole wall of the exploration hole. Then, the technician releases the fixing plate 11 from the ground and removes the water inrush sealing device from the exploration hole.
