A layered water stop device for geological drilling

Abstract

This utility model discloses a layered water-stopping device for geological drilling, relating to the field of hydrogeological research technology. The utility model includes a fixing plate, on which a positioning mechanism and a water-taking mechanism are installed. By incorporating the positioning mechanism, the handle is fixed to an external crane via ropes. The crane then lowers the entire device into the drilled pit and drives an electric push rod to move the positioning sleeve downwards. As the positioning sleeve moves downwards, it causes the piston rod and piston to move against the inner wall of the sealing tube. This forces the piston to squeeze the gas inside the sealing tube into the air bladders through the four sealing tubes, causing the air bladders to expand. The expanded air bladders contact and compress the inner wall of the pit, thus fixing the entire device at a predetermined depth. This ensures precise positioning of the target water layer during water intake, effectively preventing displacement of the equipment in the pit due to water flow and significantly improving the efficiency and accuracy of layered water intake.

Description

[0001] This utility model belongs to the field of hydrogeological research technology, and in particular relates to a layered water-stopping device for geological drilling. Background Technology

[0002] Hydrogeology is a branch of geology that refers to the various changes and movements of groundwater in nature. It mainly studies the distribution and formation patterns of groundwater, its physical properties and chemical composition, groundwater resources and their rational utilization, and the adverse effects of groundwater on engineering construction and mining, as well as their prevention and control. With the development of science and the needs of production and construction, hydrogeology has been further divided into sub-disciplines such as regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, mineral deposit hydrogeology, and soil improvement hydrogeology. In recent years, hydrogeology has permeated research with geothermal, earthquake, and environmental geology, forming several new fields.

[0003] When extracting water in layers from a drilled deep pit, the water flow in the deep pit environment often causes the equipment to shift, making it difficult to maintain a stable water extraction position, which in turn reduces the efficiency and accuracy of layered water extraction. Utility Model Content

[0004] The purpose of this invention is to provide a stratified water-stopping device for geological drilling, which solves the problem that when extracting water in stratified layers in a drilled deep pit, the water flow factors in the deep pit environment often cause the equipment to easily shift, making it difficult to maintain a stable water extraction position, thereby reducing the efficiency and accuracy of stratified water extraction.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a layered water-stopping device for geological drilling, including a fixing plate, on which a positioning mechanism and a water-taking mechanism are provided;

[0007] The positioning mechanism includes four fixed rods fixedly connected to the bottom surface of the fixed plate. The bottom ends of the four fixed rods are fixedly connected to fixed sleeves. An airbag is fixedly connected to the outer wall of the fixed sleeve. A sealing tube is fixedly connected to the inner wall of the fixed sleeve. Four air tubes are connected to the airbag. The ends of the four air tubes away from the airbag extend into the interior of the sealing tube. The four air tubes are fixedly connected to the sealing tube.

[0008] Furthermore, an electric push rod is fixedly connected to the inner wall of the fixing plate, and two handles are fixedly connected to the top surface of the fixing plate.

[0009] Furthermore, a positioning sleeve is fixedly connected to the output end of the electric push rod, and the positioning sleeve is slidably sleeved on the outer wall of the sealing tube.

[0010] Furthermore, the outer wall of the positioning sleeve is provided with four cross grooves, and the inner wall of the fixing sleeve is fixedly connected with four cross sliders, and the four cross sliders are slidably connected to the inner walls of the four cross grooves respectively.

[0011] Furthermore, a connecting ring is fixedly connected to the outer wall of the positioning sleeve, and all four fixing rods slide through the connecting ring.

[0012] Furthermore, a piston rod is fixedly connected to the inner top wall of the positioning sleeve, and a piston is fixedly connected to the bottom end of the piston rod, with the piston in contact with the inner wall of the sealing tube.

[0013] Furthermore, the water-taking mechanism includes a water-taking bucket fixedly connected to the bottom end of the positioning sleeve, and two partitions are fixedly connected to the inner wall of the water-taking bucket.

[0014] Furthermore, the three partitions divide the interior of the water bucket into three cavities, and valve fittings are fixedly connected to the inner walls of the three cavities inside the water bucket. The ends of the three valve fittings that are away from the water bucket extend to the outside of the water bucket.

[0015] This utility model has the following beneficial effects:

[0016] 1. Equipped with a positioning mechanism, when stratified water extraction is required inside a drilled deep pit, the handle is secured to an external crane via ropes. The crane then lowers the entire device into the drilled pit and drives an electric push rod to move the positioning sleeve downwards. As the positioning sleeve moves downwards, it causes the piston rod and piston to move against the inner wall of the sealing tube. This forces the piston to squeeze the gas inside the sealing tube into the air bladder through the four sealing tubes, causing the air bladder to expand. The expanded air bladder contacts and compresses the inner wall of the deep pit, thus fixing the entire device at the predetermined depth. This ensures precise positioning of the target water layer during water extraction, effectively preventing displacement of the equipment in the deep pit due to water flow and significantly improving the efficiency and accuracy of stratified water extraction.

[0017] 2. By setting up a water sampling mechanism, after the entire device is fixed at a predetermined depth in the pit, the airbag can accurately position the entire device on the water surface. At this time, after opening the three valve fittings, the water sampling bucket will be submerged in the water, and water samples from different depths of the pit will be taken in layers. After the water sampling operation is completed, the water sampling bucket and fixing plate are hoisted back to the ground using the handle, and the water samples are classified and stored. This device can not only achieve efficient and accurate layered sampling, but also is easy to operate and is suitable for various well depths and water environments, greatly improving the efficiency of water sampling.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a layered water-stopping device for geological drilling, including a fixing plate 1, on which a positioning mechanism 2 and a water-taking mechanism 3 are provided;

[0029] The positioning mechanism 2 includes four fixed rods 21 fixedly connected to the bottom surface of the fixed plate 1. A fixed sleeve 22 is fixedly connected to the bottom end of each of the four fixed rods 21. An airbag 23 is fixedly connected to the outer wall of the fixed sleeve 22, and a sealing tube 24 is fixedly connected to the inner wall of the fixed sleeve 22. Four air pipes 25 are connected to the airbag 23, with one end of each air pipe 25 extending into the interior of the sealing tube 24. All four air pipes 25 and the sealing tube 24 are fixedly connected. An electric push rod 26 is fixedly connected to the inner wall of the fixed plate 1. Two handles 4 are fixedly connected to the top surface of the fixed plate 1. A positioning sleeve 27 is fixedly connected to the output end of the electric push rod 26. The positioning sleeve 27 is slidably fitted onto the outer wall of the sealing tube 24. Four cross-shaped sliding grooves 271 are formed on the outer wall of the positioning sleeve 27, and four cross-shaped sliding blocks 272 are fixedly connected to the inner wall of the fixed sleeve 22. Four cross sliders 272 are slidably connected to the inner walls of four cross grooves 271 respectively. A connecting ring 273 is fixedly connected to the outer wall of the positioning sleeve 27. Four fixing rods 21 slide through the connecting ring 273. A piston rod 28 is fixedly connected to the inner top wall of the positioning sleeve 27. A piston 29 is fixedly connected to the bottom end of the piston rod 28. The piston 29 contacts the inner wall of the sealing tube 24. By setting the positioning mechanism 2, the piston 29 squeezes the gas inside the sealing tube 24 into the airbag 23 through the four sealing tubes 24 respectively, causing the airbag 23 to expand. The expanded airbag 23 contacts and compresses the inner wall of the deep pit, thereby fixing the entire device at the predetermined depth. This ensures that the device can be accurately positioned at the target water layer when taking water. This not only effectively prevents the equipment from shifting in the deep pit due to water flow factors, but also greatly improves the efficiency and accuracy of stratified water taking.

[0030] The water intake mechanism 3 includes a water intake bucket 31 fixedly connected to the bottom of the positioning sleeve 27. Two partitions 32 are fixedly connected to the inner wall of the water intake bucket 31, and the three partitions 32 divide the interior of the water intake bucket 31 into three cavities. Valve fittings 33 are fixedly connected to the inner walls of the three cavities inside the water intake bucket 31. The ends of the three valve fittings 33 that are away from the water intake bucket 31 extend to the outside of the water intake bucket 31. By setting up the water intake mechanism 3, the water intake bucket 31 will be submerged in the water to sample water at different depths. After the water intake operation is completed, the water intake bucket 31 and the fixing plate 1 are hoisted back to the ground by the handle 4, and the water samples are classified and stored. This device can not only achieve efficient and accurate stratified sampling, but also is easy to operate and is suitable for various well depths and water environments, greatly improving the efficiency of water intake.

[0031] A specific application of this embodiment is as follows: By setting up a positioning mechanism 2, when it is necessary to extract water in layers inside the drilled deep pit, the handle 4 is fixed to the external crane by ropes, so that the crane puts the whole device into the drilled deep pit and drives the electric push rod 26 to move the positioning sleeve 27 downward. When the positioning sleeve 27 moves downward, it will drive the piston rod 28 and piston 29 to move on the inner wall of the sealing tube 24, so that the piston 29 squeezes the gas inside the sealing tube 24 into the air bladder 23 through the four sealing tubes 24, causing the air bladder 23 to expand. The expanded air bladder 23 contacts and squeezes the inner wall of the deep pit, thereby fixing the whole device at the predetermined depth, ensuring that the target water layer can be accurately positioned when extracting water. This not only effectively prevents the equipment from being displaced in the deep pit due to water flow factors, but also greatly improves the efficiency and accuracy of layered water extraction.

[0032] By setting up the water intake mechanism 3, after the entire device is fixed at a predetermined depth in the deep pit, the airbag 23 can accurately position the entire device on the water surface. At this time, after opening the three valve fittings 33 respectively, the water intake bucket 31 will be submerged in the water to sample the water at different depths. After the water intake operation is completed, the water intake bucket 31 and the fixing plate 1 are hoisted back to the ground by the handle 4, and the water samples are classified and stored. This device can not only achieve efficient and accurate stratified sampling, but also is easy to operate and is suitable for various well depths and water environments, greatly improving the efficiency of water intake.
