Description

Technical Field

[0001] This invention relates to the field of water-stopping devices, and more particularly to an automated layered water-stopping device for hydrogeological exploration. Background Technology

[0002] Hydrogeological exploration, also known as hydrogeological survey, refers to the hydrogeological investigation and research conducted to ascertain the hydrogeological conditions of a region. Its aim is to understand the formation, distribution, and movement patterns of groundwater and surface water. During hydrogeological exploration drilling, it is necessary to stop the water seepage point within the drilled borehole to facilitate further exploration.

[0003] Patent application number 202121138472.5 discloses a layered water-stopping device for hydrogeological exploration. The layered water-stopping structure includes a limiting and fixing ring uniformly fixedly assembled on the outer wall of a pipe, water-stopping parts with bottom surfaces conforming to the limiting and fixing rings uniformly sleeved on the outer wall of the pipe, and extrusion rings uniformly sleeved on the outer wall of the pipe. Electric push rods are fixedly assembled on both sides of the upper surface of the operating table, and connecting rods are fixedly connected to the lower ends of the electric push rods. Fixing rings conforming to the extrusion rings are uniformly fixedly assembled on the outer walls of the connecting rods. The layered water-stopping structure performs layered water-stopping on the borehole, separating multiple water layers. Water pumps are uniformly installed on the outer wall of the pipe to pump water and sample the water layers in each interval, simplifying the layered sampling process and improving work efficiency. When the layered water-stopping structure performs water-stopping operation on the borehole, the extruded rubber rings expand and fill the inner wall of the borehole, separating the borehole. The manufacturing cost is low and the sealing effect is good.

[0004] However, the number of water-stopping layers that the aforementioned devices and similar devices can achieve is limited. For example, the number of water-stopping layers in the aforementioned patent depends on the number of water-stopping rings, resulting in limited effectiveness and requiring improvement. Summary of the Invention

[0005] The purpose of this invention is to provide an automated layered water-stopping device for hydrogeological exploration to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] Preferably, the outlet of the small water pump is fixedly connected to one end of the connecting pipe, and the other end of the connecting pipe is fixedly connected to and communicates with the bottom of the outlet pipe. The outlet pipe is vertically arranged and passes through a third partition. The third partition is slidably engaged with the outlet pipe, and the edge of the third partition is slidably connected to the inner wall of the water-stop pipe. The bottom of the third partition is fixedly connected to the upper end of the first spring, and the lower end of the first spring is fixedly connected to the top of the small water pump. A first controller is fixedly installed on the top of the small water pump. A first self-resetting control button is provided on the top of the first controller. The first controller is wirelessly connected to the small water pump and is used to control the start and stop of the small water pump.

[0009] Preferably, the through hole is located above the third partition.

[0010] Preferably, a limiting ring is fixedly sleeved at the top of the liquid outlet pipe, and the limiting ring is located above the third partition.

[0011] Preferably, a sealing plug is provided through the bottom side of the waterstop pipe, and the sealing plug is threadedly connected to the waterstop pipe.

[0012] Preferably, the top of the inner wall of the waterstop pipe is threaded to the drill rod, and the drill rod is connected to the drilling machine.

[0013] Preferably, a second partition is provided at the top of the waterstop pipe, and the edge of the second partition is slidably connected to the inner wall of the waterstop pipe; the top of the second partition is fixedly connected to the bottom end of a plurality of second springs, the top end of the second springs is fixedly connected to the bottom of the first partition, and the edge of the first partition is fixedly connected to the inner wall of the waterstop pipe; a second controller is fixedly provided at the bottom of the first partition, and a second self-resetting control button is provided at the bottom of the second controller; the second controller is wirelessly connected to the drilling rig, and the second controller is used to control the opening and closing of the drilling rig.

[0014] The beneficial effects of this invention are:

[0015] When this device is in use, if water is encountered at a point of leakage in the borehole, water enters the stop pipe through the through-hole. Under water pressure, the second and third baffles move, pressing the second and first self-reset control buttons respectively, stopping the drilling rig. Simultaneously, a small water pump operates, drawing out the sealing agent and overflowing it through the through-hole to seal the water outlet in the borehole, thus effectively sealing the leak. This device does not require multiple layers of water-stopping structures; it stops and outputs sealing agent to plug the leak whenever it is encountered, without limitation on the number of water-stopping layers.

[0025] Example 1

[0026] like Figure 1-5 As shown, the automated layered water-stopping device for hydrogeological exploration includes a water-stopping pipe 5, inside which a fourth partition 17 is installed, the edge of which is fixedly connected to the inner wall of the water-stopping pipe 5; the top of the inner wall of the water-stopping pipe 5 is threadedly connected to a drill rod, which is connected to a drilling rig. The drilling rig drives the drill rod to move downward along the borehole, and the drill rod drives the water-stopping pipe 5 to move downward.

[0027] A rechargeable mini water pump 18 is fixedly mounted on the top surface of the fourth partition 17. The inlet of the mini water pump 18 is fixedly connected to the upper end of the inlet pipe 4. The lower end of the inlet pipe 4 passes through the fourth partition 17 and extends to the bottom of the waterstop pipe 5. A fifth partition 6 is provided at the bottom of the waterstop pipe 5, and the edge of the fifth partition 6 is fixedly connected to the inner wall of the waterstop pipe 5. The mini water pump 18 is used to extract the sealing agent between the fourth partition 17 and the fifth partition 6. Multiple through holes 3 are opened along the circumference of the waterstop pipe 5. The through holes 3 are located above the fourth partition 17 and the third partition 14. After the mini water pump extracts the sealing agent, it is discharged through the through holes 3, so that the sealing agent seals the water outlet of the borehole.

[0028] The outlet of the small water pump 18 is fixedly connected to one end of the connecting pipe 19, and the other end of the connecting pipe 19 is fixedly connected to and connected to the bottom of the outlet pipe 10. The outlet pipe 10 is vertically arranged and passes through the third partition 14. The third partition 14 and the outlet pipe 10 are slidably fitted. A limiting ring 12 is fixedly sleeved at the top of the outlet pipe 10. The limiting ring 12 is located above the third partition 14. The edge of the third partition 14 is slidably connected to the inner wall of the water-stop pipe 5. The third partition 14 and the outlet pipe 10 are set to slide together. On the one hand, the outlet pipe 10 not only has the function of conveying sealing liquid, but also has the function of guiding the third partition 14 to slide up and down, preventing the third partition 14 from being stuck.

[0029] The bottom of the third partition 14 is fixedly connected to the upper end of the first spring 15, and the lower end of the first spring 15 is fixedly connected to the top of the small water pump 18. A first controller 16 is fixedly installed on the top of the small water pump 18, and a first self-reset control button 13 is provided on the top of the first controller 16. The first controller 16 is wirelessly connected to the small water pump 18 and is used to control the start and stop of the small water pump 18. When a leak is encountered in the borehole, water flows into the stop pipe 5 through the through hole 3, driving the third partition 14 to move down, causing the third partition 14 to press down the first self-reset control button 13. This allows the first controller 16 to control the small water pump 18 to start extracting sealing agent to seal the leak in the borehole. When the third partition 14 stops pressing down the first self-reset control button 13, the first controller 16 controls the small water pump 18 to stop extracting sealing agent.

[0030] A sealing plug 8 is installed through the bottom side of the waterstop pipe 5, and the sealing plug 8 is threadedly connected to the waterstop pipe 5. After removing the sealing plug 8, a sealing agent can be injected into the waterstop pipe 5. The sealing agent is stored between the fourth partition 17 and the fifth partition 6. After injection, the sealing plug 8 is reconnected to the waterstop pipe 5.

[0031] A second partition 2 is provided at the top of the waterstop pipe 5, and the edge of the second partition 2 is slidably connected to the inner wall of the waterstop pipe 5. The top of the second partition 2 is fixedly connected to the bottom end of multiple second springs 9, the top of the second springs 9 is fixedly connected to the bottom of the first partition 1, and the edge of the first partition 1 is fixedly connected to the inner wall of the waterstop pipe 5. A second controller 20 is fixedly provided at the bottom of the first partition 1, and a second self-resetting control button 21 is provided at the bottom of the second controller 20. The second controller 20 is wirelessly connected to the drilling rig and is used to control the opening and closing of the drilling rig. When the waterstop pipe 5 moves to the leaking point of the borehole, water flows into the waterstop pipe 5 through the through hole 3. Under the action of water pressure, the second partition 2 moves upward to press the second self-resetting control button 21, so that the second controller 20 controls the drilling rig to close, fixes the position of the waterstop pipe 5, and causes the small water pump 18 to draw sealing agent to seal the water outlet.

[0032] Working principle: When in use, the drilling rig drives the water stop pipe 5 to move downward along the borehole through the drill rod. When it encounters the water outlet inside the borehole, water flows into the water stop pipe 5 through the through hole 3. Under the action of water pressure, the second partition 2 moves upward and compresses the second spring 9, causing the second partition 2 to press the second self-reset control button 21, which causes the second controller 20 to control the drilling rig to shut down, so that the water stop pipe 5 no longer moves downward.

[0033] Simultaneously, under the action of water pressure, the third partition 14 moves down to compress the first spring 15, causing the third partition 14 to press the first self-reset control button 13, causing the first controller 16 to control the small water pump 18 to start, causing the small water pump 18 to draw the sealing agent stored between the fourth partition 17 and the fifth partition 6 through the liquid inlet pipe 4, and then deliver it to the space between the second partition 2 and the third partition 14 through the connecting pipe 19 and the liquid outlet pipe 10, so that the sealing agent overflows outward through the through hole 3 to seal the leak in the drill hole.

[0034] After a period of time, the drill rod and water stop pipe 5 are moved upwards and removed. After re-injecting the sealing agent into the water stop pipe 5, the drill rod and water stop pipe 5 are moved downwards to seal the remaining water outlets in the borehole.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
