Description

Technical Field

[0001] The invention belongs to the field of hydrogeological exploration, in particular to a water gushing plugging device for a hydrogeological exploration hole. Background Art

[0002] Geological exploration is the abbreviation of geological exploration work. In a broad sense, it can generally be understood as a synonym for geological work. It is a survey and research work with different focuses on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area according to the needs of economic construction, national defense construction, and scientific and technological development. There are different types of geological exploration work according to different purposes. In the process of geological exploration, staff need to open holes on the ground to take soil samples in order to determine the deep geological structure of the area. When the samples are taken away and taken to the laboratory for testing, the geological exploration sampling holes will be directly exposed to the external environment. When the location of the exploration hole is close to the underground waterway, the underground river water will easily penetrate into the hole and gush out from the opening end of the exploration hole, which will have an adverse impact on the surrounding ecological environment.

[0003] The general method of sealing the exploration hole is to pour cement slurry inside. However, some exploration holes have extended to underground rivers. When pouring cement slurry, the cement slurry will directly sink into the underground river. In this case, it is difficult to seal the exploration hole with cement slurry, resulting in a waste of cement slurry. After pouring cement slurry into the exploration hole, gaps are likely to exist in the middle of the cement slurry, causing groundwater to penetrate upward along the gaps. In addition, the hole wall in the exploration hole is not necessarily flat, and the poured cement slurry is difficult to fit with the hole wall of the exploration hole, resulting in insufficient adhesion of the cement slurry. When the water pressure below is too high, the solidified cement is easily pushed out of the exploration hole.

[0004] To this end, the present invention provides a water gushing plugging device for a hydrogeological survey hole. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve the problem that some exploration holes have extended to underground rivers, when pouring cement slurry, the cement slurry will directly sink into the underground river, so it is difficult to seal the exploration hole with cement slurry, resulting in a waste of cement slurry.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 11As shown, the present invention provides a technical solution, a hydrogeological exploration hole water gushing plugging device, comprising a base 1, a support frame 2 is fixedly connected to the top of the base 1, a first motor 3 is fixedly connected to the top of the support frame 2, an output end of the first motor 3 passes through the support frame 2 and is fixedly connected to a screw rod 4, an outer wall of the screw rod 4 is connected to a connecting block 5 through a screw nut pair, the connecting block 5 is slidably connected to the support frame 2, one side of the connecting block 5 is fixedly connected to a support plate 6, a second motor 7 is fixedly connected to the top of the support plate 6, an output end of the second motor 7 passes through the support plate 6 and is fixedly connected to a limiting plate 8, an outer wall of the limiting plate 8 is slidably connected to a bracket 9, a cavity 11 is opened inside the bracket 9, the limiting plate 8 fits the inner wall of the cavity 11, a first spring 10 is fixedly connected to the bottom of the inner wall of the cavity 11, the top of the first spring 10 is fixedly connected to the limiting plate 8, the inside of the bracket 9 and located in the cavity 1 A feed chamber 19 is opened below the base 1, a collar 21 is rotatably connected to the outer wall of the bracket 9, a feed trough 22 is opened inside the collar 21, a plurality of feed ports 20 are equidistantly opened on the outer wall of the bracket 9 and located inside the collar 21, a plurality of discharge ports 23 are equidistantly opened on the outer wall of the bracket 9 and located below the collar 21, both the feed port 20 and the discharge port 23 are communicated with the feed chamber 19, an extension plate 25 is fixedly connected to the outer wall of the bracket 9 and located below the feed chamber 19, the top of the extension plate 25 is set as a continuous curved surface, a material accumulation chamber 48 is opened inside the base 1, a feed port 49 is opened on the top of the base 1, the feed port 49 is communicated with the material accumulation chamber 48, a mud pump 26 is fixedly connected to the outer wall of the base 1, and a hose 27 is connected to the output end of the mud pump 26, one end of the hose 27 extends to the inside of the material accumulation chamber 48, and the other end of the hose 27 extends to the inside of the feed trough 22.

[0025] Through the above technical solution, the base 1 is moved to the exploration hole, cement slurry is loaded into the material accumulation chamber 48, the first motor 3 is started, the screw rod 4 is driven to rotate, the connecting block 5 is moved downward, the support plate 6 is driven to move downward, and the bracket 9 is moved downward. After the bracket 9 moves downward, it enters the exploration hole, and the mud pump 26 is started to pump the cement slurry in the material accumulation chamber 48 to the inside of the feed trough 22 along the hose 27. The cement slurry flows in the feed trough 22 and enters the feed chamber 19 along the feed port 20. The cement slurry entering the feed chamber 19 flows out along the discharge port 23, and through the diversion of the extension plate 25, the cement slurry can flow in accordance with the hole wall of the exploration hole, so as to facilitate the cement slurry to fit the hole wall of the exploration hole.

[0026] Specifically, the bottom of the support plate 6 is rotatably connected to a turntable 12, the inner wall of the turntable 12 is symmetrically fixedly connected to two top blocks 13, the outer wall of the bracket 9 is symmetrically fixedly connected to two top rods 18, one side of the two top blocks 13 is set as an inclined surface, and a limiting component is set at the bottom of the support plate 6.

[0027] By means of the above technical scheme, while cement slurry is injected into the exploration hole, the second motor 7 is started to drive the limit plate 8 to rotate clockwise, so that the bracket 9 rotates clockwise, and drives the push rod 18 to rotate clockwise. When the push rod 18 rotates to the position of the top block 13, it presses against the inclined surface on one side of the top block 13. Under the action of the limit assembly, the turntable 12 cannot rotate clockwise. As the push rod 18 continues to rotate, under the extrusion of the top block 13, the push rod 18 moves upward, drives the bracket 9 to move upward, and the extension plate 25 moves upward. After the bracket 9 moves upward, the first spring 10 is pressed tightly. When the top block 13 is pressed, the push rod 18 moves upward. When the rod 18 rotates to a position away from the top block 13, the bracket 9 and the extension plate 25 vibrate downward under the action of the bracket 9's own weight and the elastic force of the first spring 10, and thus reciprocate. While injecting cement slurry, the bracket 9 and the extension plate 25 continue to vibrate downward, which is convenient for compacting the cement slurry in the exploration hole and preventing the formation of bubbles and other gaps inside the cement slurry, which causes groundwater to penetrate upward. After the exploration hole is sealed and the bracket 9 is retracted, the bracket 9 is controlled to vibrate downward by the second motor 7, which is convenient for shaking off the cement slurry adhered to the bracket 9 and avoiding excessive cement slurry adhering to the bracket 9 and making it inconvenient to clean.

[0028] Specifically, the limiting assembly includes a limiting ring 14, which is fixedly installed at the bottom of the support plate 6. The inner wall of the limiting ring 14 is symmetrically slidably connected to two clamping blocks 16. The interior of the limiting ring 14 is symmetrically fixedly connected to two second springs 15. The two second springs 15 are respectively fixedly connected to the two clamping blocks 16. The outer walls of the two clamping blocks 16 are both set to inclined surfaces, and the outer wall of the turntable 12 is provided with a clamping groove 17 for cooperating with the clamping block 16.

[0029] By the above technical solution, when the second motor 7 is started and the limit plate 8 is driven to rotate clockwise, the bracket 9 is rotated clockwise, and the push rod 18 is driven to rotate clockwise. When the push rod 18 rotates to the position of the top block 13, it presses against the inclined surface on one side of the top block 13. At this time, under the action of the second spring 15, the straight surface on one side of the clamping block 16 presses against the clamping groove 17. The limit of the clamping block 16 makes the turntable 12 unable to rotate clockwise. Therefore, when the limit plate 8 rotates clockwise, the turntable 12 is in a fixed state, and the second motor 7 is started to drive the limit plate 8 to rotate counterclockwise. When the lever 18 is in motion, the bracket 9 is rotated counterclockwise, driving the push rod 18 to rotate counterclockwise. When the push rod 18 rotates to the position of the top block 13, it presses against the straight surface on the other side of the top block 13. Under the push of the push rod 18, the top block 13 is driven to rotate counterclockwise. At this time, the slot 17 presses against the inclined surface on the other side of the block 16. Under the extrusion of the slot 17, the block 16 moves and compresses the second spring 15. After the block 16 moves, it separates from the slot 17. Therefore, when the limit plate 8 rotates counterclockwise, the turntable 12 is driven to rotate accordingly, and the bracket 9 cannot vibrate downward.

[0030] Specifically, the bottom of the bracket 9 is slidably connected to the movable frame 41, the inside of the bracket 9 is rotatably connected to the tension spring 42, the bottom of the tension spring 42 is fixedly connected to the movable frame 41, the inner wall of the movable frame 41 is fixedly connected to the second hydraulic cylinder 43, the output end of the second hydraulic cylinder 43 is fixedly connected to the bottom plate 46, the bottom of the movable frame 41 is equidistantly rotatably connected to a plurality of first rotating rods 44, the bottoms of the plurality of first rotating rods 44 are rotatably connected to second rotating rods 45, and the plurality of second rotating rods 45 are rotatably connected to the bottom plate 46.

[0031] Through the above technical solution, when the exploration hole extends into the underground river, the second hydraulic cylinder 43 controls the bottom plate 46 to move upward, driving the plurality of second rotating rods 45 to rotate upward, so that the plurality of first rotating rods 44 rotate upward. After the plurality of first rotating rods 44 rotate upward, they open to each other and press against the hole wall of the exploration hole, thereby supporting the falling cement slurry and preventing the cement slurry from continuously falling into the underground river. When the plurality of first rotating rods 44 press against the exploration hole, as the bracket 9 rotates, the movable frame 41 and the tension spring 42 rotate in the bracket 9, and when the bracket 9 moves upward, the movable frame 41 slides in the bracket 9.

[0032] Specifically, a rubber pad 47 is fixedly connected between two adjacent first rotating rods 44 .

[0033] Through the above technical solution, before injecting cement slurry, a demoulding agent is applied to the outer wall of the rubber pad 47, and several first rotating rods 44 are rotated upward and then spread apart from each other. Under the pulling force of two adjacent first rotating rods 44, the rubber pad 47 is pulled apart, and the fallen cement slurry is tightly blocked by the pulled apart rubber pad 47. After the initially injected layer of cement slurry is dried, the bottom plate 46 is controlled to move downward by the second hydraulic cylinder 43, so that the second rotating rod 45 and the first rotating rod 44 are reset, and the rubber pad 47 is driven to fold again. At this time, the bracket 9 is moved upward to move the bottom plate 46 to the top of the dried cement slurry, and then cement slurry is continuously injected into the exploration hole, and the newly injected cement slurry is supported by the initially dried cement slurry.

[0034] Specifically, the outer wall of the bracket 9 is equidistantly connected to a plurality of first lower pressure plates 28 for rotation below the extension plate 25, the outer wall of the bracket 9 is fixedly connected to a fixed ring 32 below the first lower pressure plate 28, the inner wall of the fixed ring 32 is slidably connected to a sliding shaft 33, the top of the sliding shaft 33 is fixedly connected to a movable ring 35, the top of the movable ring 35 is equidistantly fixedly connected to a plurality of top plates 36, the top plates 36 are used in conjunction with the first lower pressure plate 28, the bottom of the sliding shaft 33 is fixedly connected to a limiting block 37, the outer wall of the sliding shaft 33 is sleeved with a third spring 34, the top of the third spring 34 is fixedly connected to the movable ring 35, the bottom of the third spring 34 is fixedly connected to the fixed ring 32, and an adjustment component is provided inside the bracket 9.

[0035] Through the above technical solution, after the bracket 9 enters the exploration hole, the first lower pressure plate 28 is pushed to rotate downward by the adjusting component, so that the first lower pressure plate 28 penetrates into the hole wall of the exploration hole, and then the bracket 9 is controlled to rotate counterclockwise by the second motor 7 to rotate the first lower pressure plate 28. Through the rotation of the first lower pressure plate 28, an annular groove can be opened on the hole wall of the exploration hole. While the first lower pressure plate 28 rotates, it pushes the top plate 36 to move downward, so that the movable ring 35 moves downward and compresses the third spring 34. After a groove is opened, the squeezing of the first lower pressure plate 28 by the adjusting component is released. Under the action of the third spring 34, the top plate 36 is driven to reset, so that the first lower pressure plate 28 is upward. Rotate and reset. At this time, the height of the bracket 9 is adjusted by the first motor 3, and the above operation is repeated again to make the first lower pressure plate 28 open a plurality of grooves on the wall of the exploration hole. At this time, the injected cement slurry can enter the grooves and form protrusions. The multiple protrusions outside the cement slurry can increase the adhesion of the dry cement slurry to prevent the dry cement slurry from being lifted up due to excessive groundwater pressure. After the multiple grooves are opened, the first lower pressure plate 28 is controlled to rotate downward again, so that the first lower pressure plate 28 is rotated to a position close to the wall of the exploration hole, and the bracket 9 is controlled to rotate clockwise by the second motor 7, so that the first lower pressure plate 28 rotates and vibrates downward at the same time, so as to facilitate the compaction of the cement slurry in the exploration hole.

[0036] Specifically, the adjustment component includes a first hydraulic cylinder 38, which is fixedly installed inside the bracket 9. The output end of the first hydraulic cylinder 38 is fixedly connected to a slider 39, and the outer wall of the slider 39 is fixedly connected to a plurality of protrusions 40 at equal intervals. The protrusions 40 and the slider 39 are both slidably connected to the bracket 9. One end of the protrusion 40 extends to the outside of the bracket 9, and the protrusion 40 is used in conjunction with the first lower pressure plate 28.

[0037] Through the above technical solution, the first hydraulic cylinder 38 is started to drive the slider 39 to move downward, so that the protrusion 40 moves downward, and the first lower pressure plate 28 is pushed to rotate downward by the protrusion 40, so that the first lower pressure plate 28 penetrates into the wall of the exploration hole. After a groove is opened, the slider 39 is controlled to move upward by the first hydraulic cylinder 38, so that the protrusion 40 moves upward. After the extrusion of the protrusion 40 is lost, under the action of the third spring 34, the top plate 36 is driven to reset, so that the first lower pressure plate 28 rotates upward and resets.

[0038] Specifically, one side of the first lower pressure plate 28 is fixedly connected to an extrusion block 30, and both sides of the extrusion block 30 are set as inclined surfaces. One side of the first lower pressure plate 28 and below the extrusion block 30 are fixedly connected to a plurality of second lower pressure plates 29 at equal intervals. The other side of the first lower pressure plate 28 is fixedly connected to a partition plate 31, and both sides of the partition plate 31 are set as inclined surfaces.

[0039] Through the above technical scheme, by setting both sides of the extrusion block 30 as inclined surfaces, it is convenient to insert the extrusion block 30 into the wall of the exploration hole, and it is convenient to open a larger annular groove. When the first lower pressure plate 28 vibrates downward, it drives several second lower pressure plates 29 to vibrate downward. Through the cooperation of the second lower pressure plates 29, the cement slurry can be better squeezed downward. By setting both sides of the partition plate 31 as inclined surfaces, when the first lower pressure plate 28 rotates upward, it is convenient for the cement slurry to quickly slide off the first lower pressure plate 28, preventing the first lower pressure plate 28 from holding up too much cement slurry.

[0040] Specifically, a diverter block 24 is fixedly connected to the bottom of the inner wall of the feed chamber 19, and the outer wall of the diverter block 24 is configured as a continuous curved surface.

[0041] Through the above technical solution, the diverter block 24 is set to facilitate the cement slurry entering the feed chamber 19 to flow quickly to the discharge port 23, and prevent the cement slurry from accumulating in the feed chamber 19 when the cement slurry is vibrated downward to clean it.

[0042] Specifically, the base 1 is internally rotatably connected to a rotating shaft 50, one end of which extends to the interior of the material accumulation chamber 48, and the outer wall of the rotating shaft 50 is equidistantly and fixedly connected to a plurality of stirring rods 51, the bottom of the screw rod 4 extends to the interior of the base 1 and is fixedly connected to a first bevel gear 52, and the outer wall of the rotating shaft 50 is fixedly connected to a second bevel gear 53, and the first bevel gear 52 is meshingly connected to the second bevel gear 53.

[0043] Through the above technical solution, the screw rod 4 rotates and drives the first bevel gear 52 to rotate, which in turn drives the second bevel gear 53 to rotate, which drives the rotating shaft 50 to rotate, and causes the plurality of stirring rods 51 to rotate. By rotating the plurality of stirring rods 51, the cement slurry in the accumulation chamber 48 is stirred to prevent the cement slurry from being deposited.

[0044] When in use, the base 1 is moved to the exploration hole, cement slurry is loaded into the material accumulation chamber 48, the first motor 3 is started, the screw rod 4 is driven to rotate, the connecting block 5 is moved downward, the support plate 6 is driven to move downward, and the bracket 9 is moved downward. The screw rod 4 rotates and drives the first bevel gear 52 to rotate, the second bevel gear 53 is rotated, the rotating shaft 50 is driven to rotate, and the plurality of stirring rods 51 are rotated. By rotating the plurality of stirring rods 51, it is convenient to stir the cement slurry in the material accumulation chamber 48 to prevent the cement slurry from being deposited. After the bracket 9 moves downward, it enters the exploration hole, the first hydraulic cylinder 38 is started, the slider 39 is driven to move downward, the protrusion 40 is moved downward, and the first lower pressing plate 28 is pushed downward by the protrusion 40 to rotate, so that the extrusion block 30 is inserted into the hole wall of the exploration hole. The second motor 7 is then started, and when the limit plate 8 is driven to rotate counterclockwise, the bracket 9 is rotated counterclockwise, and the push rod 18 is driven to rotate counterclockwise. When the push rod 18 rotates to the position of the top block 13, it presses against the straight surface on the other side of the top block 13. Under the push of the push rod 18, the top block 13 is driven to rotate counterclockwise. At this time, the slot 17 presses against the inclined surface on the other side of the block 16. Under the extrusion of the slot 17, the block 16 moves and presses the second spring 15. After the block 16 moves, it separates from the slot 17, so that when the limit plate 8 rotates counterclockwise, the turntable 12 is driven to rotate accordingly. While the bracket 9 rotates, the extrusion block 30 is driven to rotate, thereby opening an annular groove on the wall of the exploration hole. The first lower pressure plate 28 rotates while pushing the top plate 36 to move downward. The movable ring 35 moves downward to compress the third spring 34. After a groove is opened, the slider 39 is controlled to move upward by the first hydraulic cylinder 38, so that the protrusion 40 moves upward. After the extrusion of the protrusion 40 is lost, the top plate 36 is driven to reset under the action of the third spring 34, so that the first lower pressing plate 28 rotates upward and resets. At this time, the height of the bracket 9 is adjusted by the first motor 3, and the above operation is repeated again, so that the first lower pressing plate 28 opens multiple grooves on the hole wall of the exploration hole. At this time, the injected cement slurry can enter the groove and form a protrusion. The multiple protrusions outside the cement slurry can increase the adhesion of the dry cement slurry, and prevent the dry cement slurry from being lifted up due to excessive groundwater pressure. The mud pump 26 is started to pump the cement slurry in the accumulation chamber 48 along the hose 27 The cement slurry is pumped to the inside of the feed trough 22, and flows in the feed trough 22 and enters the feed chamber 19 along the feed port 20. The cement slurry entering the feed chamber 19 flows out along the discharge port 23 and is guided by the extension plate 25 so that the cement slurry can flow along the wall of the exploration hole, which is convenient for the cement slurry to fit the wall of the exploration hole. The first hydraulic cylinder 38 is started to drive the slider 39 to move downward, so that the protrusion 40 moves downward, and the first lower pressure plate 28 is pushed to rotate downward by the protrusion 40, so that the first lower pressure plate 28 rotates to a position close to the wall of the exploration hole. The second motor 7 is started to drive the limit plate 8 to rotate clockwise, so that the bracket 9 rotates clockwise, and the push rod 18 rotates clockwise. When the push rod 18 rotates to the position of the top block 13, it presses against the inclined surface on one side of the top block 13.At this time, under the action of the second spring 15, the straight surface of one side of the card block 16 presses against the card slot 17, and the card block 16 is limited to prevent the turntable 12 from rotating clockwise. Therefore, when the limit plate 8 rotates clockwise, the turntable 12 is in a fixed state. As the push rod 18 continues to rotate, under the extrusion of the top block 13, the push rod 18 moves upward, driving the bracket 9 to move upward, so that the extension plate 25 moves upward. After the bracket 9 moves upward, the first spring 10 is pressed. When the push rod 18 rotates to a position away from the top block 13, under the action of the weight of the bracket 9 itself and the elastic force of the first spring 10, the first lower The pressing plate 28 and the extension plate 25 vibrate downward, and thus reciprocate. While injecting cement slurry, the first lower pressing plate 28 and the extension plate 25 continue to vibrate downward, which is convenient for compacting the cement slurry in the exploration hole and preventing bubbles and other gaps from appearing inside the cement slurry, causing groundwater to penetrate upward. When the first lower pressing plate 28 vibrates downward, it drives several second lower pressing plates 29 to vibrate downward. Through the cooperation of the second lower pressing plates 29, the cement slurry can be squeezed downward better. By setting both sides of the partition plate 31 as inclined surfaces, when the first lower pressing plate 28 rotates upward, it is convenient for the cement slurry to quickly slide off the first lower pressing plate 28 In order to prevent the first lower pressure plate 28 from lifting too much cement slurry, when the exploration hole extends into the underground river, a demoulding agent is applied to the outer wall of the rubber pad 47 before injecting cement slurry, and the second hydraulic cylinder 43 controls the bottom plate 46 to move upward, driving a plurality of second rotating rods 45 to rotate upward, so that a plurality of first rotating rods 44 rotate upward, and after the plurality of first rotating rods 44 rotate upward, they open to each other, and under the pulling force of two adjacent first rotating rods 44, the rubber pad 47 is pulled apart, and the pulled apart rubber pad 47 is used to strictly block the falling cement slurry, and wait for the initially injected layer of cement slurry to dry and solidify. After that, the second hydraulic cylinder 43 controls the bottom plate 46 to move downward, so that the second rotating rod 45 and the first rotating rod 44 are reset, and the rubber pad 47 is driven to fold again. At this time, the bracket 9 is moved upward to move the bottom plate 46 to the top of the dry cement slurry. Then, the cement slurry is continuously injected into the exploration hole, and the newly injected cement slurry is supported by the initial dry cement slurry. After the exploration hole is plugged and the bracket 9 is retracted, the second motor 7 controls the limit plate 8 to rotate clockwise, so that the bracket 9 continues to vibrate downward, so as to shake off the cement slurry adhering to the bracket 9, and avoid the bracket 9 adhering to too much cement slurry and making it inconvenient to clean.
