Description

Technical Field

[0001] This utility model relates to the field of cave exploration devices, specifically a cave exploration device for cave treatment. Background Technology

[0002] The main purpose of cave exploration is to comprehensively understand the distribution, morphology, scale, and stability of underground caves, providing a scientific basis for engineering construction, resource development, and environmental protection. Specific objectives include: assessing the impact of caves on infrastructure such as buildings, bridges, and tunnels to ensure engineering safety; identifying caves that may cause disasters such as ground subsidence and settlement to formulate preventive measures; exploring the potential of caves as underground water storage and transport channels to rationally develop water resources; and analyzing the water quality of underground water in caves to ensure drinking water safety.

[0003] In existing technologies, the exploration of caves generally involves the use of specific mechanical tools to investigate the environment during the exploration process. Depending on the exploration objective, different layers of soil are collected for testing. However, traditional cave exploration equipment usually uses heavy machinery. When excavating soft soil for sampling, the installation and use of heavy machinery often results in a waste of human and material resources. Furthermore, the damp cave environment can damage electrical appliances, making it difficult to use heavy machinery for excavation and sampling. Utility Model Content

[0004] To overcome the shortcomings of existing technology, heavy machinery often wastes human and material resources when excavating soft soil for sampling, and the damp cave environment can damage electrical appliances. Therefore, a lighter device should be used for excavation and sampling. This utility model proposes a surveying device for cave treatment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a surveying device for karst cave treatment, including a base, a rotating cylinder fixedly connected to the top of the base, a support rod fixedly connected to one side of the base, a top plate fixedly connected to one end of the support rod, and a sampling mechanism provided on one side of the base.

[0006] The sampling mechanism includes a screw cylinder, the surface of which is threadedly connected to the inner wall of a rotating cylinder, a drill bit fixedly connected to the bottom of the screw cylinder, a sampling groove formed on the surface of the screw cylinder, the number of which is set to several, a sampling tube slidably connected to the inner wall of the screw cylinder, and a piston ring slidably connected to the inner wall of the sampling tube.

[0007] Preferably, a first valve is rotatably connected to the inner wall of the piston ring, and a second valve is rotatably connected to the inner wall of the sampling cylinder.

[0008] Preferably, a connecting rod is fixedly connected to one side of the piston ring, and the surface of the connecting rod is slidably connected to the inner cavity of the top plate.

[0009] Preferably, the surface of the connecting rod is provided with a pin hole, and the number of pin holes is set to several. One end of the connecting rod is fixedly connected to a limit handle.

[0010] Preferably, one end of the sampling tube is provided with a ventilation opening, and a rope is fixedly connected to one end of the sampling tube, with the surface of the rope movably disposed in the inner cavity of the top plate.

[0011] Preferably, a shovel ring is fixedly connected to one end of the sampling tube, and a limit ring is fixedly connected to the inner wall of the sampling tube.

[0012] Preferably, a pedal is fixedly connected to one side of the base, and spikes are fixedly connected to the bottom of the pedal.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a sampling mechanism. The base is placed flat on a soft, moist soil surface. A foot pedal is used to drive spikes into the soil for stability. Rotating the rotating cylinder causes a screw cylinder, threaded to its inner wall, to rotate and move axially. This screw cylinder drives the drill bit to rotate, drilling through the soil and penetrating deep underground. Upon reaching the target depth, a rope is pulled to raise the sampling cylinder, which is fixedly connected to one end of the rope. As the sampling cylinder rises, the opening of the sampling slot widens, allowing moist soil, such as muddy water, to flow between the screw cylinder and the sampling cylinder. A knot is then tied in the rope to secure the sample. The cylinder is then manually pulled vertically to move the piston ring. When the piston ring moves upward, the middle area between the first and second valves expands, the air pressure in the middle area decreases, the first valve closes and the second valve opens, allowing mud and water to be drawn into the middle area. Then the piston ring moves downward, the middle area shrinks and the air pressure increases, the first valve opens and the second valve closes, allowing mud and water in the middle area to enter the sampling area above the piston ring. After repeating this cycle several times, the mud and water sample in the sampling area continuously increases, achieving the sampling effect and solving the problem of difficulty in sampling when excavating soft soil.

[0022] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a surveying device for dealing with karst caves. (Refer to...) Figures 1 to 3 A surveying device for karst cave treatment includes a base 1 with a support rod 3 fixedly connected to one side, a top plate 4 fixedly connected to one end of the support rod 3, and a sampling mechanism 5 provided on one side of the base 1.

[0025] The sampling mechanism 5 includes a screw cylinder 501, the surface of which is threadedly connected to the inner wall of the rotating cylinder 2. A drill bit 502 is fixedly connected to the bottom of the screw cylinder 501. Sampling grooves 503 are formed on the surface of the screw cylinder 501, and the number of sampling grooves 503 is set to several. A sampling cylinder 504 is slidably connected to the inner wall of the screw cylinder 501, and a piston ring 6 is slidably connected to the inner wall of the sampling cylinder 504. By setting up the sampling mechanism 5, the screw cylinder 501, which is threadedly connected to the inner wall of the rotating cylinder 2, is rotated. 01 rotates and moves axially, thereby causing the screw cylinder 501 to drive the drill bit 502 to rotate, drilling through the soil and penetrating deep underground. When the target depth is reached, the sampling cylinder 504 is raised according to different sampling requirements. When the sampling cylinder 504 is raised, the opening of the sampling groove 503 is enlarged, allowing moist soil, such as muddy water, to flow through the opening of the sampling groove 503 into the space between the bottom of the inner cavity of the screw cylinder 501 and below the second valve 8, thereby selecting the soil at the target depth to provide the necessary sample for subsequent sampling.

[0026] Reference Figure 4 A first valve 7 is rotatably connected to the inner wall of the piston ring 6, and a second valve 8 is rotatably connected to the inner wall of the sampling cylinder 504. Both the first valve 7 and the second valve 8 are connected via small hinges. Both valves are one-way valves. When the first valve 7 rotates, it will rotate around its connection point with the piston ring 6. The same applies to the connection point between the second valve 8 and the inner wall of the sampling cylinder 504. The space above the first valve 7 is the sampling area, and the space between the first valve 7 and the second valve 8 is the intermediate area. When the piston ring... When piston ring 6 moves upward, the intermediate area between the first valve 7 and the second valve 8 expands, the air pressure in the intermediate area decreases, the first valve 7 closes and the second valve 8 opens, allowing the mud and water to be drawn into the intermediate area. Then, piston ring 6 moves downward, the intermediate area shrinks and the air pressure increases, the first valve 7 opens and the second valve 8 closes, allowing the mud and water in the intermediate area to enter the sampling area above piston ring 6. After several cycles, the mud and water sample in the sampling area continuously increases, achieving the sampling effect. In addition, this structure can prevent some large impurities such as small stones from entering the sampling cylinder 504, because the impurities are large and difficult to be drawn into the sampling cylinder 504 by the pressure difference, thus achieving the filtering effect.

[0027] Reference Figure 5A connecting rod 9 is fixedly connected to one side of the piston ring 6. The surface of the connecting rod 9 is slidably connected to the inner cavity of the top plate 4. By setting the connecting rod 9, since one end of the connecting rod 9 is fixedly connected to one side of the piston ring 6, the piston ring 6 can be moved by moving the connecting rod 9. By setting the top plate 4, since the surface of the piston ring 6 is slidably connected to the inner wall of the sampling cylinder 504 and the surface of the connecting rod 9 is slidably connected to the inner cavity of the top plate 4, the connecting rod 9 can be limited from both ends to ensure that the connecting rod 9 can move axially.

[0028] Reference Figure 5 The surface of the connecting rod 9 is provided with a pin hole 10, and the number of pin holes 10 is set to several. One end of the connecting rod 9 is fixedly connected to a limit handle 11. By setting the pin hole 10, when it is necessary to fix the connecting rod 9 at a certain fixed height, the corresponding pin hole 10 is raised above the top plate, and a pin is inserted into the pin hole 10 so that the pin abuts against the upper surface of the top plate 4, thereby fixing the height of the connecting rod 9. By setting the limit handle 11, it is convenient to apply force to the connecting rod 9, and the connecting rod 9 can be limited by the top plate 4 when it is not fixed by a pin, preventing the connecting rod 9 from falling excessively.

[0029] Reference Figure 5 A vent 12 is provided at one end of the sampling cylinder 504, and a rope 13 is fixedly connected to one end of the sampling cylinder 504. The surface of the rope 13 is movably disposed in the inner cavity of the top plate 4. By setting the vent 12, the space in the sampling area will change when the first valve 7 moves axially, so that the gas in the sampling area can maintain contact with the gas outside the device through the vent 12, ensuring that the gas pressure in the sampling area is the same as the gas pressure outside the device. Since one end of the rope 13 is fixedly connected to one end of the sampling cylinder 504, the sampling cylinder 504 can be moved axially by pulling the rope 13. When the sampling cylinder 504 moves to the target position, a knot can be formed by tying the rope 13. The knot prevents the sampling cylinder 504 from passing through the top plate 4 and fixes it at the target height. If the height needs to be changed later, the knot can be untied and readjusted.

[0030] Reference Figure 4A shovel ring 14 is fixedly connected to one end of the sampling cylinder 504, and a limit ring 15 is fixedly connected to the inner wall of the sampling cylinder 504. By setting the limit ring 15, the first valve 7 and the second valve 8 can be prevented from contacting each other, thus avoiding damage. By setting the shovel ring 14, impurities such as small stones will inevitably be mixed in during soil sampling, and these impurities will be deposited at the bottom of the screw cylinder 501 and stuck between the screw cylinder 501 and the sampling cylinder 504. Due to its sloping structure, the pressure of the sampling cylinder 504 descending can be converted into a pushing force on the impurities, causing the impurities to move. Since the shovel ring 14 is slidably connected to the inner wall of the screw cylinder 501, the inner wall of the screw cylinder 501 can be cleaned when the shovel ring 14 moves.

[0031] Reference Figure 1 and Figure 2 A footboard 16 is fixedly connected to one side of the base 1, and a spike 17 is fixedly connected to the bottom of the footboard 16. By setting the footboard 16 and the spike 17, since the soft and wet soil makes it difficult to place the device horizontally, the spike 17 is driven into the soil by stepping on the footboard 16 to stabilize the device, prevent the device from tipping over due to subsequent operations, and improve the stability of the structure.

[0032] Working principle: The base 1 is placed flat on the surface of soft, moist soil. The spikes 17 are driven into the soil by stepping on the pedal 16 to stabilize the device. Rotating the rotating cylinder 2 causes the screw cylinder 501, which is threaded to the inner wall of the rotating cylinder 2, to rotate and move axially. This causes the screw cylinder 501 to drive the drill bit 502 to rotate, drilling through the soil and penetrating deep underground. When the target depth is reached, the rope 13 is pulled according to different sampling requirements, raising the sampling cylinder 504, which is fixedly connected to one end of the rope 13. As the sampling cylinder 504 rises, the opening of the sampling groove 503 is exposed, allowing moist soil, such as muddy water, to flow through the opening of the sampling groove 503 into the space between the bottom of the inner cavity of the screw cylinder 501 and below the second valve 8. The knotted rope 13 then... The sampling cylinder 504 is secured with a knot. Then, the piston ring 6 is moved by manually pulling the limit handle 11 vertically. When the piston ring 6 moves upward, the middle area between the first valve 7 and the second valve 8 becomes larger, the air pressure in the middle area decreases, the first valve 7 closes and the second valve 8 opens, allowing the mud and water to be sucked into the middle area. Then, the piston ring 6 moves downward, the middle area becomes smaller and the air pressure increases, the first valve 7 opens and the second valve 8 closes, allowing the mud and water in the middle area to enter the sampling area above the piston ring 6. After repeating this cycle several times, the mud and water sample in the sampling area continuously increases. When enough sample is collected, the rotating cylinder 2 is rotated in the opposite direction to raise the screw cylinder 501 and the sampling cylinder 504, achieving the sampling effect.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
