Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster investigation, in particular to a geological disaster investigation and sampling device. Background Art

[0002] In the field of geological disaster investigation, obtaining accurate and complete samples is crucial for analyzing the causes of disasters, assessing disaster risks, and formulating prevention and control measures. As a key tool for obtaining samples, the performance of geological disaster investigation sampling equipment directly affects the quality and efficiency of the investigation.

[0003] At present, the common geological disaster survey and sampling equipment on the market has obvious defects in the sample storage and transportation links. During transportation, due to unreasonable structural design, the bottom of the storage barrel of some equipment is not tightly sealed, and the samples collected on the spiral rod fan blades are easy to leak out from the bottom of the barrel; at the same time, the slide rail opening of the equipment lacks effective protection measures, which may cause the sample to spill from the slide rail opening. This not only causes sample loss and affects the accuracy of subsequent detection and analysis, but may also pollute the environment and interfere with the site due to sample leakage. In addition, the operating procedures of existing equipment are cumbersome. When performing operations such as opening and closing baffles and sealing openings, manual multi-step complex operations are often required. This not only consumes a lot of manpower and time, but also has a low degree of automation, making it difficult to meet the needs of efficient and accurate geological disaster survey work. Therefore, there is an urgent need for a geological disaster survey and sampling equipment that can ensure the stability of samples in the storage and transportation links, is easy to operate, and has a high degree of automation. Summary of the Invention

[0007] The slide rail is fixedly connected to the outer wall of the storage barrel, the inner wall of the slide rail is connected to a soft baffle through a winding assembly, the bottom end of the soft baffle is arranged on the bottom side of the lifting ring, the inner wall of the slide rail is provided with a limit slide groove, and soft strips are fixedly connected to both sides of the soft baffle, and the soft strips are arranged inside the limit slide groove;

[0008] The baffle is rotatably connected to the bottom side of the storage barrel, the outer wall of the baffle is connected to the bottom side of the lifting ring through a traction component, the bottom side of the bottom ring is rotatably connected to a winding roller, the outer wall of the winding roller is connected to the bottom side of the baffle through a stretching component, and the outer wall of the winding roller is provided with an elastic component.

[0009] Preferably, the winding assembly includes a winding shaft rotatably connected to the inner wall of the bottom end of the slide rail, and a volute spring 2 is provided at one end of the winding shaft.

[0010] Preferably, the traction assembly includes a pull rod fixedly connected to the outer wall of the baffle, a guide wheel 2 is provided on the bottom side of the bottom ring, and the outer wall of the pull rod and the bottom side of the lifting ring are connected by a traction rope.

[0011] Preferably, a limiting hole is provided on the bottom side of the bottom ring, the traction rope is arranged on the inner wall of the limiting hole, and the bottom end of the traction rope is arranged on the outer wall of the second guide wheel.

[0012] Preferably, the stretching assembly includes a winding roller rotatably connected to the top side of the bottom ring, the outer wall of the winding roller is provided with a stretching rope, the bottom end of the stretching rope is provided on the bottom side of the baffle, the outer wall of the bottom ring is provided with a guide wheel 1, and the stretching rope is provided on the outer wall of the guide wheel 1.

[0013] Preferably, the elastic component includes a shell fixedly connected to the outer wall of the bottom ring, and a spiral spring 1 is provided at one end of the winding roller, and the spiral spring 1 is provided on the inner wall of the shell.

[0014] Preferably, the drilling assembly includes a spiral rod rotatably connected to the bottom side of the fixed plate, the bottom end of the spiral rod is fixedly connected to a drill bit, the bottom side of the fixed plate is equipped with a motor through a fixing frame, and the driving end of the motor is fixedly connected to the top side of the spiral rod.

[0015] Preferably, the support assembly includes a slide rod fixedly connected to the top side of the bottom ring, the lifting ring is slidably connected to the outer wall of the slide rod, and the outer wall of the slide rod is provided with a reset spring.

[0016] Preferably, the method comprises the following steps:

[0017] Step 1: First, place the storage barrel on the ground where sampling is required through the support legs on the bottom side of the bottom ring, and then press down the lifting ring to slide the screw rod and drill bit downward on the outer wall of the sliding rod;

[0018] Step 2: When the lifting ring is pressed down to release the tension of the traction rope between it and the baffle, the scroll spring resets and drives the winding roller to rotate, winding the tension rope through the guide wheel, pulling the baffle to rotate and open on the bottom side of the storage barrel;

[0019] Step 3: Continue to press down the lifting ring to align it with the ground where sampling is required, start the motor to control the rotation of the screw rod and the drill bit to drill the ground. When drilling to a certain depth, remove the screw rod and the drill bit from the deep hole. The ground sample will remain on the fan blades of the screw rod. Continue to pull up the lifting ring to drive the soft baffle and the soft strip to move on the inner wall of the slide rail, so that the soft baffle blocks the opening of the slide rail.

[0020] Step 4. When the lifting ring continues to be pulled up, the traction rope will slide on the inner wall of the limit hole and the outer wall of the second guide wheel, and the baffle will be pulled to cover the bottom side of the storage barrel. When the lifting ring is pulled up to a certain height, the traction rope between the bottom side of the lifting ring and the pull rod will be tightened to ensure that the sample remaining on the spiral rod fan blades will not leak out from the bottom side of the storage barrel when transporting the storage barrel.

[0021] Preferably, when the lifting ring is pressed downward in step three, the spiral spring 2 drives the winding shaft to rotate to wind up and store the motor and the soft strip.

[0022] Working principle: First, place the storage barrel on the sampling ground through the support legs on the bottom side of the bottom ring. At this time, the baffle is in the closed state, and the soft baffle is stored in the limit slide groove on the inner wall of the slide rail. The spiral springs 1 and 2 are in the energy storage state. Then, press down the lifting ring to drive the fixed plate down, so that it slides along the slide rod, driving the spiral rod and drill bit downward. At the same time, the tension of the traction rope is released, and the spiral spring 1 resets and drives the winding roller to rotate. The tension rope is pulled by the guide wheel 1 so that the winding roller winds the tension rope, causing the baffle to open on the bottom side of the storage barrel; the spiral spring 2 drives the winding shaft to rotate, storing the soft baffle and, exposing the slide rail opening, to ensure that the lifting ring moves inside the slide rail. Then continue to press down the lifting ring to align the spiral rod and drill bit with the ground, start the motor to drill and sample, stop the motor after drilling to a certain depth, remove the spiral rod and drill bit, and the sample remains on the spiral rod fan blades. Then pull up the lifting ring, which will drive the soft baffle and soft strip to seal the opening of the slide rail to prevent the sample from scattering from the opening of the slide rail; at the same time, the lifting ring will drive the traction rope to pull the baffle to close the bottom side of the storage barrel through the limit hole and guide wheel 2. When the lifting ring is pulled up to a certain height, the traction rope is tightened to ensure that the sample will not leak from the bottom side of the storage barrel.

[0023] The present invention provides a geological disaster survey and sampling device, which has the following beneficial effects:

[0024] 1. The present invention cooperates with the soft baffle and the slide rail limiting groove. When the lifting ring is pulled up, the soft baffle blocks the slide rail opening. At the same time, the traction rope pulls the baffle to cover the bottom side of the storage barrel. When the lifting ring is raised to a certain height, the traction rope is tightened. The dual structure ensures that the samples on the spiral rod fan blades will not leak from the bottom side of the storage barrel or the slide rail opening during transportation, thereby ensuring the stability of the sampled samples during storage and transportation.

[0025] 2. The present invention can realize the opening and closing of the baffle and the blocking of the slide rail opening by the soft baffle by pressing down and pulling up the lifting ring, thereby reducing the complicated manual operations and improving the convenience of use. It also realizes the automatic actions such as the winding of the stretch rope by the winding roller and the storage of the soft baffle by the winding shaft, thereby improving the degree of automation of the equipment.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example:

[0035] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a geological disaster survey and sampling device, including:

[0036] The top side of the storage barrel 1 is fixedly connected to a fixing ring 2, the bottom end of the storage barrel 1 is fixedly connected to a bottom ring 8, a slide rod 3 is fixedly connected to the top side of the bottom ring 8, a lifting ring 6 is slidably connected to the outer wall of the slide rod 3, the outer wall of the slide rod 3 is provided with a return spring 4, the inner wall of the storage barrel 1 is provided with a lifting ring 6, the bottom side of the bottom ring 8 is provided with a supporting leg, the inner wall of the lifting ring 6 is fixedly connected to a fixing plate 24, a spiral rod 12 is rotatably connected to the bottom side of the fixing plate 24, the bottom end of the spiral rod 12 is fixedly connected to a drill bit 23, a motor 9 is installed on the bottom side of the fixing plate 24 through a fixing frame, and the driving end of the motor 9 is fixedly connected to the top side of the spiral rod 12 for geological sampling;

[0037] Specifically, the fixing ring 2 fixed on the top side of the storage barrel 1 can be used to connect with other devices or structures to facilitate the installation and fixation of the equipment. The bottom ring 8 fixed at the bottom end plays the role of supporting and connecting other components, ensuring the overall stability and structural integrity of the equipment. The top side of the bottom ring 8 is fixedly connected to the slide rod 3, and the outer wall of the slide rod 3 is slidably connected to the lifting ring 6, so that the lifting ring 6 can move up and down on the slide rod 3. The outer wall of the slide rod 3 is also provided with a reset spring 4. When the equipment is working, when the lifting ring 6 is moved downward by an external force, the reset spring 4 is compressed to store energy. After the external force disappears, the reset spring 4 quickly releases energy, driving the lifting ring 6 to return to its initial position, thereby improving the automation level and operational convenience of the equipment. A fixed plate 24 is fixedly connected to the inner wall of the lifting ring 6. A motor 9 is mounted on the bottom side of the fixed plate 24 via a fixed bracket. The drive end of the motor 9 is fixedly connected to the top side of the screw rod 12, and the bottom end of the screw rod 12 is fixedly connected to the drill bit 23. The rotation of the motor 9 drives the screw rod 12 and the drill bit 23 to rotate at high speed, thereby achieving geological drilling and sampling operations. This structural design not only ensures the stability and efficiency of the equipment during the sampling process, but also provides reliable technical support for geological disaster investigation work.

[0038] Please see the attached Figure 3 , Attachment Figure 4 and attached Figure 6 The slide rail 5 is fixedly connected to the outer wall of the storage barrel 1, and is rotatably connected to the winding shaft 19 on the inner wall of the bottom end of the slide rail 5. One end of the winding shaft 19 is provided with a volute spring 20. The bottom end of the soft baffle 7 is provided on the bottom side of the lifting ring 6. A limiting slide groove is provided on the inner wall of the slide rail 5. Soft strips 21 are fixedly connected on both sides of the soft baffle 7. The soft strips 21 are provided inside the limiting slide groove.

[0039] Specifically, the slide rail 5 is fixedly connected to the outer wall of the storage barrel 1, providing important support and guidance, and providing a stable path for the movement of the soft baffle 7. A winding shaft 19 is rotatably connected to the inner wall of the bottom end of the slide rail 5. A second spiral spring 20 is provided at one end of the winding shaft 19, enabling the winding shaft 19 to automatically wind under the elastic action of the second spiral spring 20. When the lifting ring 6 moves up and down, the bottom end of the soft baffle 7 moves along the bottom side of the lifting ring 6, thereby achieving the operation of blocking or opening the opening of the slide rail 5. The inner wall of the slide rail 5 is specially provided with a limited slide groove, and soft strips 21 are fixedly connected on both sides of the soft baffle 7. The soft strips 21 are embedded in the limited slide groove, which not only limits the moving direction of the soft baffle 7 and ensures that it slides smoothly in the slide rail 5, but also effectively prevents the soft baffle 7 from deflecting or twisting during movement, thereby ensuring the sealing and reliability of the equipment during sampling and transportation, and avoiding the sampled sample from leaking from the opening of the slide rail 5. The soft baffle 7 can be made of silicone, which has good flexibility and can slide smoothly in the slide rail 5 with the movement of the lifting ring 6. At the same time, it can fit closely to the inner wall of the slide rail 5 when blocking the opening of the slide rail 5, avoiding gaps that cause sample leakage. Since the soft baffle 7 needs to move frequently in the slide rail 5 during use of the equipment, it generates friction with the inner wall of the slide rail 5, so it needs to have high wear resistance to extend its service life. It may contain various corrosive substances. The soft baffle 7 needs to have a certain degree of corrosion resistance to prevent it from being damaged by corrosion of the sample. It has sufficient strength to withstand the tension when the lifting ring 6 is pulled up, as well as the external force impact that may be received during transportation, to avoid cracking or deformation; the soft strip 21 can be made of rubber. The soft strip 21 needs to be embedded in the limiting slide groove of the slide rail 5 and move with the soft baffle 7. Therefore, it needs to have good flexibility and elasticity, be able to slide flexibly in the limiting slide groove, and be able to return to its original shape when squeezed, to ensure smooth movement of the soft baffle 7. When the soft strip 21 moves in the limiting slide groove, it generates friction with the inner wall of the slide groove, and needs to have high wear resistance to reduce wear and ensure the long-term stable operation of the equipment. It has good dimensional stability and will not expand or contract significantly due to changes in environmental factors such as temperature and humidity during use, to avoid affecting the movement and sealing effect of the soft baffle 7.

[0040] Please see the attached Figure 3 -Attached Figure 5The baffle 11 is rotatably connected to the bottom side of the storage barrel 1, and a pull rod 25 is fixedly connected to the outer wall of the baffle 11. A guide wheel 2 13 is provided on the bottom side of the bottom ring 8. The outer wall of the pull rod 25 and the bottom side of the lifting ring 6 are connected by a traction rope 14. A limiting hole 22 is provided on the bottom side of the bottom ring 8. The traction rope 14 is arranged on the inner wall of the limiting hole 22. The bottom end of the traction rope 14 is arranged on the outer wall of the guide wheel 2 13. The bottom side of the bottom ring 8 is rotatably connected to the winding roller 15, and the winding roller 15 is rotatably connected to the top side of the bottom ring 8. The outer wall of the winding roller 15 is provided with a stretching rope 10. The bottom end of the stretching rope 10 is arranged on the bottom side of the baffle 11. The outer wall of the bottom ring 8 is provided with a guide wheel 18. The stretching rope 10 is arranged on the outer wall of the guide wheel 18. The outer shell 16 is fixedly connected to the outer wall of the bottom ring 8. One end of the winding roller 15 is provided with a volute spring 17, and the volute spring 17 is arranged on the inner wall of the outer shell 16.

[0041] Specifically, the baffle 11 is installed on the bottom side of the storage barrel 1 and can be flexibly opened and closed, thereby controlling the opening and closing of the bottom of the storage barrel 1. The pull rod 25 on the outer wall of the baffle 11 is connected to the bottom side of the lifting ring 6 through the traction rope 14, so that the up and down movement of the lifting ring 6 can drive the opening and closing of the baffle 11. A guide wheel 2 is provided on the bottom side of the bottom ring 8. The bottom end of the traction rope 14 passes around the outer wall of the guide wheel 2 13. The function of the guide wheel 2 13 is to change the force direction of the traction rope 14 so that it can pull the baffle 11 more smoothly. At the same time, a limiting hole 22 is provided on the bottom side of the bottom ring 8. The traction rope 14 passes through the inner wall of the limiting hole 22. The limiting hole 22 can limit the position of the traction rope 14 to prevent it from deviating or entangled during movement. The bottom side of the bottom ring 8 is also rotatably connected to the winding roller 15. The outer wall of the winding roller 15 is provided with a stretching rope 10. The bottom end of the stretching rope 10 is fixed to the bottom side of the baffle 11. When the baffle 11 rotates, the stretch rope 10 can be wound or released on the winding roller 15, thereby controlling the opening and closing of the baffle 11. The outer wall of the bottom ring 8 is provided with a guide wheel 18, and the stretch rope 10 passes around the outer wall of the guide wheel 18. The function of the guide wheel 18 is similar to that of the guide wheel 2 13, both of which are to change the direction of force applied to the stretch rope 10 to ensure that it can smoothly pull the baffle 11. In addition, the outer wall of the bottom ring 8 is also fixedly connected to the outer wall of the housing 16, and the interior of the housing 16 is provided with a spiral spring 17, one end of which is connected to the winding roller 15. When the baffle 11 is opened, the spiral spring 17 is stretched to store energy. Once the baffle 11 needs to be closed, the spiral spring 17 can quickly release energy, driving the stretch rope 10 through the winding roller 15 to pull the baffle 11 closed, thereby realizing the automatic reset function, improving the automation level and operational convenience of the equipment.

[0042] Please see the attached Figure 1 , Attachment Figure 3 and attached Figure 4 A geological disaster survey sampling method comprises the following steps:

[0043] Step 1: First, place the storage barrel 1 on the ground where sampling is required through the support legs on the bottom side of the bottom ring 8, and then press down the lifting ring 6 to slide the screw rod 12 and the drill bit 23 downward on the outer wall of the slide rod 3;

[0044] Specifically, when placing the storage barrel 1, it is necessary to ensure that the supporting legs are firmly in contact with the ground to prevent the equipment from tilting; when pressing down the lifting ring 6, it is necessary to apply force evenly so that the lifting ring 6 moves vertically downward along the slide rod 3, ensuring that the downward movement trajectory of the spiral rod 12 and the drill bit 23 is perpendicular to the ground, laying the foundation for the accuracy of subsequent drilling and sampling.

[0045] Step 2: When the tension of the traction rope 14 between the lifting ring 6 and the baffle 11 is released, the spiral spring 17 is reset to drive the winding roller 15 to rotate, and the tension rope 10 is wound through the guide wheel 18, pulling the baffle 11 to rotate and open at the bottom side of the storage barrel 1;

[0046] Specifically, when the lifting ring 6 is pressed down to release the tension of the traction rope 14, the spiral spring 17 releases its elastic potential energy due to the initial compression state, driving the winding roller 15 to rotate clockwise, and the tension rope 10 is wound onto the outer wall of the winding roller 15 under the guidance of the guide wheel 18. At this time, the baffle 11 rotates counterclockwise around the rotating axis on the bottom side of the storage barrel 1, and the opening angle needs to ensure that the spiral rod 12 and the drill bit 23 can smoothly contact the ground for drilling operations.

[0047] Step 3: Continue to press down the lifting ring 6 to align it with the ground where sampling is required, start the motor 9 to control the rotation of the screw rod 12 and the drill bit 23 to drill the ground. When drilling to a certain depth, the screw rod 12 and the drill bit 23 are removed from the drilled deep hole. The ground sample will remain on the fan blades of the screw rod 12. Continue to pull up the lifting ring 6 to drive the soft baffle 7 and the soft strip 21 to move on the inner wall of the slide rail 5, so that the soft baffle 7 blocks the opening of the slide rail 5. When the lifting ring 6 in step 3 is pressed down, the scroll spring 20 drives the winding shaft 19 to rotate to wind up the motor 9 and the soft strip 21;

[0048] Specifically, the drilling depth needs to be determined according to the needs of geological disaster investigation, and can be precisely controlled by marking the scale on the slide bar 3 or recording the downward stroke of the lifting ring 6. The fan blades of the spiral rod 12 are designed to be a spiral structure. After the drill bit 23 drills through the stratum, the rotating fan blades will transport soil, rock and other samples upward along the spiral groove and attach them to the gap between the fan blades. When taking them out, they need to be lifted up slowly to prevent the samples from falling off due to centrifugal force. When the lifting ring 6 is pressed down, the spiral spring 20 drives the winding shaft 19 to rotate, and the soft baffle 7 and the soft strip 21 are wound and stored to the bottom of the slide rail 5. At this time, the opening of the slide rail 5 is exposed to allow the lifting ring 6 to move down; when the lifting ring 6 is pulled up, the soft baffle 7 moves up synchronously with the lifting ring 6, and the soft strip 21 slides in the limiting slide groove to ensure that the soft baffle 7 flatly blocks the opening of the slide rail 5 to prevent the sample from spilling from the gap of the slide rail 5.

[0049] Step 4: When the lifting ring 6 continues to be pulled upward, the traction rope 14 will slide on the inner wall of the limiting hole 22 and the outer wall of the second guide wheel 13, pulling the baffle 11 to cover the bottom side of the storage barrel 1. When the lifting ring 6 is pulled up to a certain height, the traction rope 14 between the bottom side of the lifting ring 6 and the pull rod 25 is tightened, ensuring that the sample remaining on the fan blades of the spiral rod 12 will not leak out from the bottom side of the storage barrel 1 when the storage barrel 1 is transported;

[0050] Specifically, when the lifting ring 6 is pulled up, the traction rope 14 generates an upward pulling force on the baffle 11 through the limiting hole 22 and the guide wheel 2 13, causing the baffle 11 to rotate clockwise around the rotating axis until it completely covers the bottom side of the storage barrel 1; when the lifting ring 6 is pulled up to the top of the slide rod 3, the traction rope 14 is in a taut state. At this time, the baffle 11 is tightly fitted with the sealing surface on the bottom side of the storage barrel 1, and cooperates with the soft baffle 7 to block the slide rail 5, forming a double leak-proof structure, ensuring that the sample is completely enclosed in the storage barrel 1 during transportation, and avoiding leakage of the sample from the bottom of the barrel or the opening of the slide rail 5 due to factors such as bumps.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The geological disaster survey and sampling equipment according to claim 1, characterized in that: The support assembly includes a slide rod (3) fixedly connected to the top side of the bottom ring (8), the lifting ring (6) is slidably connected to the outer wall of the slide rod (3), and the outer wall of the slide rod (3) is provided with a reset spring (4).

9. A geological disaster survey sampling method, using any one of the geological disaster survey sampling equipment according to claims 1-8, characterized in that: The following steps are involved: Step 1: First, place the storage barrel (1) on the ground where sampling is required through the support legs on the bottom side of the bottom ring (8), and then press down the lifting ring (6) to slide the screw rod (12) and the drill bit (23) on the outer wall of the slide rod (3); Step 2: When the lifting ring (6) is pressed downward to release the tension of the traction rope (14) between the lifting ring (6) and the baffle (11), the spiral spring (17) is reset to drive the winding roller (15) to rotate, and the tension rope (10) is wound through the guide wheel (18), and the baffle (11) is pulled to rotate and open at the bottom side of the storage barrel (1); Step 3: Continue to press down the lifting ring (6) to align it with the ground where sampling is required, start the motor (9) to control the rotation of the screw rod (12) and the drill bit (23) to drill the ground. When drilling to a certain depth, remove the screw rod (12) and the drill bit (23) from the drilled deep hole. The ground sample will remain on the fan blades of the screw rod (12). Continue to pull up the lifting ring (6) to drive the soft baffle (7) and the soft strip (21) to move on the inner wall of the slide rail (5), so that the soft baffle (7) blocks the opening of the slide rail (5); Step 4: When the lifting ring (6) continues to be pulled up, the traction rope (14) will slide on the inner wall of the limiting hole (22) and the outer wall of the second guide wheel (13), and the baffle (11) will be pulled to cover the bottom side of the storage barrel (1). When the lifting ring (6) is pulled up to a certain height, the traction rope (14) between the bottom side of the lifting ring (6) and the pull rod (25) is tightened to ensure that the sample remaining on the fan blades of the spiral rod (12) will not leak out from the bottom side of the storage barrel (1) when the storage barrel (1) is transported.

10. A geological disaster survey sampling method according to claim 9, characterized in that: When the lifting ring (6) in step three is pressed down, the spiral spring (20) drives the winding shaft (19) to rotate to wind up and store the motor (9) and the soft strip (21).
