Description

Technical Field

[0001] This utility model belongs to the field of water-drilling prevention technology, specifically relating to a water-stopping diversion device for preventing water-drilling construction. Background Technology

[0002] Borehole water diversion and sealing refers to the use of water-stopping and diversion devices during geological water control drilling to isolate aquifers and prevent water from different aquifers from mixing during borehole operation, thereby ensuring the accuracy and safety of testing. Borehole water diversion and sealing is widely used in hydrogeological drilling, especially when it is necessary to determine the water level, quality, and quantity of each aquifer. Effective water-stopping and diversion measures ensure the accuracy and reliability of test data while guaranteeing construction safety.

[0003] Chinese patent with publication number CN222253903U discloses a water diversion device for geological water control drilling. This device uses a series of complex structures to connect and fix the pipeline, which is inconvenient for workers to disassemble and install. At the same time, the pipeline has relatively few diversion ports, making it difficult to meet the diversion needs of multiple pipelines.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a water diversion prevention device for preventing water drilling construction.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a water-stopping diversion device for preventing water drilling construction, which can solve the problems of complex connection structure and few diversion ports in water-stopping diversion devices.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A water-stopping and diversion device for preventing water drilling construction includes: a pipe, a water-stopping and diversion mechanism, and at least one branch pipe;

[0009] The water-stopping and diversion mechanism is connected to the insertion tube. The water-stopping and diversion mechanism includes a main connecting pipe, which is connected to the insertion tube via a flange. Multiple diversion pipes are connected to the main connecting pipe, and a water-stopping mechanism is installed inside each diversion pipe.

[0010] The branch pipe is connected to the shunt pipe.

[0011] In one or more embodiments of this utility model, the branch pipe is internally connected to the main connecting pipe, the main connecting pipe is provided with a connecting end, and the branch pipe is threaded to the connecting end. The branch pipe is connected to the connecting end by means of threaded connection, which facilitates quick assembly and disassembly of the branch pipe.

[0012] In one or more embodiments of this utility model, the water-stopping mechanism includes a partition plate, which is fixedly connected to the inner wall of the diversion pipe and is used to isolate the diversion pipe.

[0013] The partition plate is provided with multiple through holes. When the through holes are not blocked, the liquid in the diversion pipe can flow through the through holes and into the branch pipe.

[0014] In one or more embodiments of this utility model, a sliding rod is slidably provided on the partition plate, and a first sealing plate and a second sealing plate are respectively connected to the two ends of the sliding rod. The first sealing plate covers the through hole, and the second sealing plate covers the connecting end. When the first sealing plate covers the through hole and the second sealing plate covers the connecting end, the diversion pipe is in a cut-off state, and the liquid cannot flow at this time.

[0015] In one or more embodiments of this utility model, the slide bar is a polygonal column, which makes the slide bar difficult to rotate, ensuring the coverage effect of the first sealing plate on the through hole, and ensuring the coverage effect of the second sealing plate on the connection end;

[0016] The diameter of the second sealing plate is larger than the diameter of the connecting end, ensuring that the second sealing plate covers the connecting end.

[0017] In one or more embodiments of this utility model, an elastic sleeve is provided on the outside of the slide rod. The elastic sleeve is disposed between the partition and the second sealing plate. When the first sealing plate is not pulled, the elastic sleeve applies a force to the second sealing plate, so that the second sealing plate can cover the connection end and the first sealing plate can cover the through hole, thereby making the diversion pipe in a cut-off state.

[0018] In one or more embodiments of this utility model, a pull rope is connected to the center of the side of the first sealing plate away from the slide rod, and a screw is connected to the end of the pull rope. The screw passes through the side wall of the diversion pipe. When the operator pulls the screw, the first sealing plate can be moved in the diversion pipe by pulling the pull rope, so that the second sealing plate can be removed from the cover of the connection end, and the first sealing plate can be removed from the cover of the through hole, thereby making the diversion pipe in a passable state.

[0019] In one or more embodiments of this utility model, a guide rod is rotatably connected inside the diversion pipe, and the pull rope passes around the guide rod to guide the pull rope and facilitate the movement of the first sealing plate.

[0020] In one or more embodiments of this utility model, a sealing ring is provided on the side wall of the diversion pipe, and the screw passes through the sealing ring, so that the liquid in the diversion pipe is not easy to leak through the gap between the screw and the diversion pipe. Both the elastic sleeve and the sealing ring are made of rubber.

[0021] In one or more embodiments of this utility model, a fastening nut is threaded to one end of the screw located outside the diversion pipe. By utilizing the cooperation between the screw and the fastening nut, the moving position of the first sealing plate can be fixed, eliminating the need for workers to constantly pull the screw, thereby reducing the burden on workers and keeping the diversion pipe in a passable state.

[0022] Compared with the prior art, the water diversion device for preventing water drilling construction of this utility model can optimize the connection structure of water diversion, making it convenient for workers to disassemble and assemble. At the same time, it can increase the number of diversion ports to meet the needs of multiple diversions during water drilling construction. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figures 1 to 6 As shown, a water-stopping and diversion device for preventing water drilling construction in one embodiment of the present invention includes an insertion pipe 1, a water-stopping and diversion mechanism 2, and at least one branch pipe 3.

[0034] The insertion tube 1 is located inside the wall, and a reinforcement layer is filled between the insertion tube 1 and the wall.

[0035] like Figures 1 to 6 As shown, the water-stopping and diversion mechanism 2 is connected to the insertion tube 1. The water-stopping and diversion mechanism 2 is used to isolate the aquifer, so that the water in different aquifers is not easily mixed.

[0036] The diversion mechanism 2 includes a main connecting pipe 201, which is connected to the insertion pipe 1 via a flange, facilitating connection between the insertion pipe 1 and the main connecting pipe 201 and enabling easy assembly and disassembly by workers. Multiple branch pipes 202 are connected to the main connecting pipe 201, and these branch pipes 202 are internally connected to the main connecting pipe 201, allowing connection to different branch pipes 3 to meet the diversion requirements of multiple pipelines.

[0037] In addition, the main connecting pipe 201 is provided with a connecting end 2021, and the branch pipe 3 is threaded to the connecting end 2021. The branch pipe 3 is connected to the connecting end 2021 by means of threaded connection, which can simplify the connection structure between the branch pipe 202 and the branch pipe 3 and facilitate the quick assembly and disassembly of the branch pipe 3.

[0038] like Figures 1 to 6 As shown, a water-stopping mechanism is installed inside the diversion pipe 202, which can control the opening and closing of the diversion pipe 202, and can also save the cost of installing ball valves or other control valves.

[0039] The water-stopping mechanism includes a partition 203, which is fixedly connected to the inner wall of the diversion pipe 202 and is used to block the diversion pipe 202.

[0040] In addition, the partition plate 203 is provided with multiple through holes. When the through holes are not blocked, the liquid in the diversion pipe 202 can flow through the through holes and flow into the branch pipe 3.

[0041] Specifically, a sliding rod 204 is slidably mounted on the partition 203. A first sealing plate 205 and a second sealing plate 206 are respectively connected to both ends of the sliding rod 204. The diameter of the second sealing plate 206 is larger than the diameter of the connecting end 2021, ensuring the second sealing plate 206 effectively covers the connecting end 2021. The first sealing plate 205 covers the through hole, and the second sealing plate 206 covers the connecting end 2021. When the first sealing plate 205 covers the through hole and the second sealing plate 206 covers the connecting end 2021, the diversion pipe 202 is in a cut-off state, and liquid cannot flow within the diversion pipe 202.

[0042] Preferably, the slide bar 204 is a polygonal column, which makes the slide bar 204 difficult to rotate, ensuring the coverage effect of the first sealing plate 205 on the through hole, and ensuring the coverage effect of the second sealing plate 206 on the connecting end 2021.

[0043] like Figures 1 to 6 As shown, an elastic sleeve 207 is provided on the outer side of the slide bar 204, and the elastic sleeve 207 is disposed between the partition plate 203 and the second sealing plate 206. When the first sealing plate 205 is not pulled, the elastic sleeve 207 applies a force to the second sealing plate 206, so that the second sealing plate 206 can cover the connecting end 2021, and the first sealing plate 205 can cover the through hole, thereby causing the diversion pipe 202 to be in a cut-off state in its natural state.

[0044] In this design, a pull rope 208 is connected to the center of the side of the first sealing plate 205 away from the slide rod 204. A screw 210 is connected to the end of the pull rope 208, and the screw 210 passes through the side wall of the diversion pipe 202. When the operator pulls the screw 210, the first sealing plate 205 can be moved within the diversion pipe 202 via the pull rope 208, causing the second sealing plate 206 to detach from its cover on the connecting end 2021. This allows the first sealing plate 205 to detach from its cover on the through hole, thus opening the diversion pipe 202 into a passable state, facilitating the flow of liquid within the diversion pipe 202.

[0045] In addition, a guide rod 209 is rotatably connected inside the diversion pipe 202, and the pull rope 208 passes around the guide rod 209 to guide the pull rope 208, making it easier to pull the first sealing plate 205 to move.

[0046] Specifically, the side wall of the diversion pipe 202 is provided with a sealing ring, and the screw 210 passes through the sealing ring, so that the liquid in the diversion pipe 202 is not easy to leak through the gap between the screw 210 and the diversion pipe 202. The elastic sleeve 207 and the sealing ring are both made of rubber.

[0047] In addition, a fastening nut 211 is threaded to one end of the screw 210 located outside the diversion pipe 202. By using the cooperation between the screw 210 and the fastening nut 211, the moving position of the first sealing plate 205 can be fixed. The operator does not need to pull the screw 210 all the time, which can reduce the operator's burden and keep the diversion pipe 202 in a passable state.

[0048] like Figures 1 to 6 As shown, the branch pipe 3 is connected to the diversion pipe 202 to achieve liquid diversion.

[0049] In practical use, the main connecting pipe 201 is connected to the insert pipe 1 through a flange, and then, as needed, multiple branch pipes 3 are threaded onto multiple connecting ends 2021.

[0050] When it is necessary to keep the diversion pipe 202 in a passable state, pull the screw 210. The screw 210 pulls the pull rope 208, which then passes around the guide rod 209 and pulls the first sealing plate 205 to move within the diversion pipe 202. This causes the second sealing plate 206 to disengage from covering the connecting end 2021, and simultaneously causes the first sealing plate 205 to disengage from covering the through hole. Tighten the fastening nut 211 to fix the position of the first sealing plate 205. At this time, the diversion pipe 202 can be in a passable state, and liquid can enter the branch pipe 3 through the diversion pipe 202, the through hole, and the connecting end 2021 to achieve diversion.

[0051] When it is necessary to keep the diverter 202 in the cut-off state, loosen the fastening nut 211, the pulling force of the pull rope 208 on the first sealing plate 205 decreases, the elastic sleeve 207 applies force to the second sealing plate 206, and the first sealing plate 205 covers the through hole again, and the second sealing plate 206 covers the connection end 2021 again. At this time, the diverter 202 can be in the cut-off state, and the liquid will not flow in the diverter 202.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
