Description

Technical Field

[0001] This invention relates to the field of geological disaster investigation technology, specifically to a geological disaster investigation and sampling device. Background Technology

[0002] In the field of geological hazard investigation, obtaining accurate and complete samples is crucial for analyzing the causes of hazards, assessing hazard risks, and developing prevention and control measures. Geological hazard investigation sampling equipment, as a key tool for obtaining samples, directly impacts the quality and efficiency of the investigation work.

[0003] Currently, commercially available geological hazard investigation and sampling equipment has significant deficiencies in sample storage and transportation. During transportation, some equipment suffers from poor structural design and inadequate sealing at the bottom of the storage container, allowing samples collected on the spiral rod blades to leak out. Furthermore, the lack of effective protective measures at the slide rail openings allows samples to spill out. This not only results in sample loss, affecting the accuracy of subsequent testing and analysis, but also risks environmental pollution and interference at the site due to leakage. In addition, existing equipment has cumbersome operating procedures. Operations such as opening and closing baffles and sealing openings often require multiple complex manual steps, consuming significant manpower and time, and exhibiting low automation levels, failing to meet the demands of efficient and accurate geological hazard investigation. Therefore, there is an urgent need for a geological hazard investigation and sampling device that can ensure sample stability during storage and transportation, is easy to operate, and has a high degree of automation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a geological disaster survey and sampling device that solves the technical problems of easy sample leakage, cumbersome operation, and low degree of automation in existing devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a geological disaster investigation and sampling device, comprising:

[0006] A storage tank, wherein a fixed ring is fixedly connected to the top side of the storage tank, a bottom ring is fixedly connected to the bottom end of the storage tank, a support component is provided on the top side of the bottom ring, a lifting ring is provided on the inner wall of the storage tank, a support leg is provided on the bottom side of the bottom ring, a fixed plate is fixedly connected to the outer wall of the lifting ring, and a drilling component is provided on the bottom side of the fixed plate for sampling the geology.

[0007] The slide rail is fixedly connected to the outer wall of the storage tank. 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 located on the bottom side of the lifting ring. A limiting groove is formed on the inner wall of the slide rail. Soft strips are fixedly connected to both sides of the soft baffle and are located inside the limiting groove.

[0008] A baffle is rotatably connected to the bottom side of the storage tank. The outer wall of the baffle is connected to the bottom side of the lifting ring via a traction assembly. A winding roller is rotatably connected to the top side of the bottom ring. The outer wall of the winding roller is connected to the bottom side of the baffle via a tension assembly. An elastic component is provided on the outer wall of the winding roller.

[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 spiral spring 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 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 disposed on the inner wall of the limiting hole, and the bottom end of the traction rope is disposed on the outer wall of the guide wheel.

[0012] Preferably, the outer wall of the winding roller is provided with a tension rope, the bottom end of the tension rope is provided on the bottom side of the baffle, the outer wall of the bottom ring is provided with a guide wheel, and the tension rope is provided on the outer wall of the guide wheel.

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

[0014] Preferably, the drilling assembly includes a spiral rod rotatably connected to the bottom side of the fixed plate, a drill bit fixedly connected to the bottom end of the spiral rod, a motor mounted on the bottom side of the fixed plate via a fixing frame, and the drive end of the motor 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 being slidably connected to the outer wall of the slide rod, and a return spring being provided on the outer wall of the slide rod.

[0016] Preferably, it includes the following steps:

[0017] Step 1: First, place the storage bucket on the ground where sampling is required using the support legs on the bottom side of the bottom ring. Then, press down the lifting ring to make it slide on the outer wall of the slide rod, causing the spiral rod and drill bit to move down.

[0018] Step 2: When the lifting ring is pressed down to loosen the tension of the traction rope between it and the baffle, the spiral spring resets and drives the winding roller to rotate. The guide wheel winds the tension rope, pulling the baffle to rotate and open at the bottom of the storage tank.

[0019] Step 3: Continue to press down the lifting ring to align it with the ground to be sampled, start the motor to control the rotation of the auger and drill bit to drill the ground. When the drilling reaches a certain depth, remove the auger and drill bit from the drilled hole. The ground sample will remain on the blades of the auger. Continue to pull up the lifting ring to drive the soft baffle and soft strip to move on the inner wall of the slide rail, so that the soft baffle seals the opening of the slide rail.

[0020] Step 4: As the lifting ring continues to pull upwards, it will cause the traction rope to slide on the inner wall of the limit hole and the outer wall of the guide wheel, pulling the baffle to cover the bottom of the storage barrel. When the lifting ring is pulled up to a certain height, the traction rope located between the bottom of the lifting ring and the pull rod will be taut, ensuring that the sample remaining on the auger blades leaks out from the bottom of the storage barrel when transporting the storage barrel.

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

[0022] Working Principle: First, the storage bucket is placed on the sampling ground via 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 limiting groove on the inner wall of the slide rail. Scroll springs one and two are in an energy-storing state. Next, the lifting ring is pressed down, causing the fixed plate to descend and slide along the slide rod, moving the auger and drill bit downwards. Simultaneously, the tension of the traction rope is released, and scroll spring one resets, driving the winding roller to rotate. Through guide wheel one, the tension rope is pulled, causing the winding roller to wind the tension rope, opening the baffle at the bottom side of the storage bucket. Scroll spring two drives the winding shaft to rotate, storing the soft baffle and exposing the slide rail opening, ensuring that the lifting ring moves inside the slide rail. Then, the lifting ring is pressed down again, aligning the auger and drill bit with the ground. The motor is started to drill and collect samples. After drilling to a certain depth, the motor is stopped, and the auger and drill bit are removed. The sample remains on the auger blades. Then, pull up the lifting ring. The lifting ring will drive the soft baffle and soft strip to block the slide rail opening and prevent the sample from falling out of the slide rail opening. At the same time, the lifting ring will drive the traction rope to pull the baffle to close the bottom of the storage tank through the limit hole and guide wheel 2. When the lifting ring is pulled up to a certain height, the traction rope will tighten to ensure that the sample will not leak out from the bottom of the storage tank.

[0023] This invention provides a geological disaster investigation and sampling device. It has the following beneficial effects:

[0024] 1. The present invention utilizes the cooperation of a soft baffle and a sliding rail limiting groove. When the lifting ring is pulled up, the soft baffle blocks the opening of the sliding rail, while the traction rope pulls the baffle to cover the bottom of the storage tank. When the lifting ring is raised to a certain height, the traction rope is tightened. This dual structure ensures that the sample on the spiral rod blade will not leak from the bottom of the storage tank or the opening of the sliding rail during transportation, thus ensuring the stability of the sample during storage and transportation.

[0025] 2. This invention enables the opening and closing of the baffle and the sealing of the slide rail opening by pressing down and pulling up the lifting ring, reducing complex manual operations and improving ease of use. It also automates the winding of the tension rope by the winding roller and the storage of the soft baffle by the winding shaft, thus improving the automation level of the equipment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example:

[0035] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a geological disaster investigation and sampling device, comprising:

[0036] A fixed ring 2 is fixedly connected to the top side of the storage tank 1, a bottom ring 8 is fixedly connected to the bottom end of the storage tank 1, 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, a return spring 4 is provided on the outer wall of the slide rod 3, a lifting ring 6 is provided on the outer wall of the storage tank 1, a support leg is provided on the bottom side of the bottom ring 8, a fixed plate 24 is fixedly connected to the inner wall of the lifting ring 6, a spiral rod 12 is rotatably connected to the bottom side of the fixed plate 24, a drill bit 23 is fixedly connected to the bottom end of the spiral rod 12, a motor 9 is installed on the bottom side of the fixed plate 24 through a fixed frame, and the drive 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 to the top side of the storage tank 1 can be used to connect with other devices or structures, facilitating the installation and fixation of the equipment. The bottom ring 8 fixed at the bottom provides support and connection to other components, ensuring the overall stability and structural integrity of the equipment. A sliding rod 3 is fixedly connected to the top side of the bottom ring 8, and a lifting ring 6 is slidably connected to the outer wall of the sliding rod 3, allowing the lifting ring 6 to move up and down on the sliding rod 3. A return spring 4 is also provided on the outer wall of the sliding rod 3. When the equipment is working, when the lifting ring 6 is subjected to external force and moves downward, the return spring 4 is compressed and stores energy. After the external force disappears, the return spring 4 quickly releases energy, driving the lifting ring 6 back to its initial position, improving the automation level and ease of operation of the equipment. A fixing 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 fixing plate 24 via a fixing frame. The drive end of the motor 9 is fixedly connected to the top side of the auger rod 12, and a drill bit 23 is fixedly connected to the bottom end of the auger rod 12. Driven by the rotation of the motor 9, the auger rod 12 and the drill bit 23 rotate at high speed, thereby realizing the drilling and sampling operations of the geology. 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 appendix Figure 3 Appendix Figure 4 and attached Figure 6 The slide rail 5 is fixedly connected to the outer wall of the storage tank 1, and the winding shaft 19 is rotatably connected to the inner wall of the bottom end of the slide rail 5. One end of the winding shaft 19 is provided with a spiral spring 20. The bottom end of the soft baffle 7 is provided on the bottom side of the lifting ring 6. The inner wall of the slide rail 5 is provided with a limiting groove. Soft strips 21 are fixedly connected to both sides of the soft baffle 7. The soft strips 21 are provided inside the limiting groove.

[0039] Specifically, the slide rail 5 is fixedly connected to the outer wall of the storage tank 1, playing an important supporting and guiding role, 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. One end of the winding shaft 19 is equipped with a spiral spring 20, enabling the winding shaft 19 to automatically wind under the elastic action of the spiral spring 20. When the lifting ring 6 moves up and down, the bottom end of the soft baffle 7 moves accordingly on the bottom side of the lifting ring 6, thereby achieving the sealing or opening operation of the opening at the slide rail 5. The inner wall of the slide rail 5 is specially designed with a limiting groove. Flexible strips 21 are fixedly connected to both sides of the soft baffle 7, and these strips 21 are embedded in the limiting groove. This not only restricts the movement direction of the soft baffle 7, ensuring its smooth sliding within the slide rail 5, but also effectively prevents the soft baffle 7 from shifting or twisting during movement. This ensures the sealing and reliability of the equipment during sampling and transportation, preventing samples from leaking out of the opening of the slide rail 5. The soft baffle 7 can be made of silicone, possessing good flexibility, allowing it to slide smoothly within the slide rail 5 along with the movement of the lifting ring 6. Simultaneously, it can tightly fit the inner wall of the slide rail 5 when sealing the opening, preventing gaps that could lead to sample leakage. Since the soft baffle 7 needs to move frequently within the slide rail 5 during equipment use, generating friction with the inner wall of the slide rail 5, it must have high wear resistance to extend its service life. The environment at geological disaster investigation sites is complex, and the samples... The sample may contain various corrosive substances, so the soft baffle 7 needs to have a certain degree of corrosion resistance to prevent damage from sample corrosion. It also needs to have sufficient strength to withstand the pulling force of the lifting ring 6 and the external impact that may occur during transportation, so as to avoid cracking or deformation. The soft strip 21 can be made of rubber and needs to be embedded in the limiting groove of the slide rail 5 and move together with the soft baffle 7. Therefore, it needs to have good flexibility and elasticity so that it can slide flexibly in the limiting groove and return to its original shape when squeezed, so as to ensure smooth movement of the soft baffle 7. When the soft strip 21 moves in the limiting groove, it will rub against the inner wall of the groove. It needs to have high wear resistance to reduce wear and ensure long-term stable operation of the equipment. It also needs to have good dimensional stability so that it will not expand or contract significantly due to changes in environmental factors such as temperature and humidity during use, so as to avoid affecting the movement and sealing effect of the soft baffle 7.

[0040] Please see the appendix Figure 3 -Appendix Figure 5A baffle 11 is rotatably connected to the bottom side of the storage tank 1. A pull rod 25 is fixedly connected to the outer wall of the baffle 11. A guide wheel 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 limit hole 22 is opened on the bottom side of the bottom ring 8. The traction rope 14 is located on the inner wall of the limit hole 22. The bottom end of the traction rope 14 is located on the outer wall of the guide wheel 13. A winding roller 15 is rotatably connected to the top side of the bottom ring 8. A tension rope 10 is provided on the outer wall of the winding roller 15. The bottom end of the tension rope 10 is located on the bottom side of the baffle 11. A guide wheel 18 is provided on the outer wall of the bottom ring 8. The tension rope 10 is located on the outer wall of the guide wheel 18. A housing 16 is fixedly connected to the outer wall of the bottom ring 8. A spiral spring 17 is provided at one end of the winding roller 15. The spiral spring 17 is located on the inner wall of the housing 16.

[0041] Specifically, the baffle 11 is installed on the bottom side of the storage tank 1, which can be flexibly opened and closed to control the opening and closing of the bottom of the storage tank 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. The bottom side of the bottom ring 8 is provided with a guide wheel 23. The bottom end of the traction rope 14 passes around the outer wall of the guide wheel 23. The function of the guide wheel 23 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, the bottom side of the bottom ring 8 is provided with a limit hole 22. The traction rope 14 passes through the inner wall of the limit hole 22. The limit hole 22 can limit the position of the traction rope 14 and prevent it from deviating or tangling during movement. The bottom side of the bottom ring 8 is also rotatably connected to a winding roller 15. The outer wall of the winding roller 15 is provided with a tension rope 10. The bottom end of the tension rope 10 is fixed to the bottom side of the baffle 11. When the baffle 11 rotates, the tension rope 10 can be wound or released on the winding roller 15, thereby controlling the opening and closing of the baffle 11. A guide wheel 18 is provided on the outer wall of the bottom ring 8. The tension 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 13, both serving to change the direction of force on the tension rope 10, ensuring that it can smoothly pull the baffle 11. In addition, a housing 16 is fixedly connected to the outer wall of the bottom ring 8. A spiral spring 17 is installed inside the housing 16. One end of the spiral spring 17 is connected to the winding roller 15. When the baffle 11 is opened, the spiral spring 17 is stretched and stores energy. Once the baffle 11 needs to be closed, the spiral spring 17 can quickly release energy, driving the tension rope 10 to pull the baffle 11 closed via the winding roller 15, thereby achieving an automatic reset function and improving the automation level and ease of operation of the equipment.

[0042] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 A geological hazard investigation and sampling method includes the following steps:

[0043] Step 1: First, place the storage bucket 1 on the ground where sampling is required by the support leg on the bottom side of the bottom ring 8, and then slide the lifting ring 6 down on the outer wall of the slide rod 3 to move the spiral rod 12 and the drill bit 23 down.

[0044] Specifically, when placing the storage tank 1, it is necessary to ensure that the support legs are firmly in contact with the ground to avoid tilting the equipment; when pressing down the lifting ring 6, force should be applied evenly so that the lifting ring 6 moves vertically down along the slide bar 3, ensuring that the downward 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 lifting ring 6 is pressed down to loosen the tension of the traction rope 14 between it and the baffle 11, the spiral spring 17 resets and drives the winding roller 15 to rotate. The guide wheel 18 winds the tension rope 10, pulling the baffle 11 to rotate and open on the bottom side of the storage tank 1.

[0046] Specifically, when the lifting ring 6 is pressed down, causing the tension of the traction rope 14 to loosen, the spiral spring 17 releases its elastic potential energy due to its initial compression state, driving the winding roller 15 to rotate clockwise. Under the guidance of the guide wheel 18, the tension rope 10 is wound onto the outer wall of the winding roller 15. At this time, the baffle 11 rotates counterclockwise around the rotating shaft on the bottom side of the storage tank 1. The opening angle must 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 to be sampled, start the motor 9 to control the rotation of the spiral rod 12 and the drill bit 23 to drill the ground. When the drilling reaches a certain depth, the spiral rod 12 and the drill bit 23 are taken out from the drilled deep hole. The ground sample will remain on the fan blade of the spiral 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 is pressed down in step 3, the spiral spring 20 drives the winding shaft 19 to rotate and wind and store the soft baffle 7 and the soft strip 21.

[0048] Specifically, the drilling depth needs to be determined according to the geological disaster investigation requirements. It 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 with a spiral structure. After the drill bit 23 breaks through the strata, the rotating fan blades will transport soil, rock and other samples upward along the spiral groove and attach them to the gaps between the fan blades. When taking them out, they need to be lifted slowly to avoid the samples 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, winding and storing the soft baffle 7 and soft strip 21 to the bottom of the slide rail 5. At this time, the opening of the slide rail 5 is exposed so that the lifting ring 6 can 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 groove to ensure that the soft baffle 7 is flat and seals the opening of the slide rail 5, preventing the samples from spilling from the gaps in the slide rail 5.

[0049] Step 4: When the lifting ring 6 continues to be pulled up, it will pull the traction rope 14 to slide on the inner wall of the limiting hole 22 and the outer wall of the 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 located between the bottom side of the lifting ring 6 and the pull rod 25 will be tightened to ensure that the sample remaining on the fan blade of the screw rod 12 leaks from the bottom side of the storage barrel 1 when transporting the storage barrel 1.

[0050] Specifically, when the lifting ring 6 is pulled up, the traction rope 14, guided by the limiting hole 22 and the guide wheel 13, exerts an upward pulling force on the baffle 11, 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 bar 3, the traction rope 14 is in a taut state. At this time, the baffle 11 is tightly fitted with the sealing surface of the bottom side of the storage barrel 1, and together with the soft baffle 7 to seal the slide rail 5, a double leak-proof structure is formed to ensure that the sample is completely sealed in the storage barrel 1 during transportation, and to prevent the sample from leaking out from the bottom of the barrel or the opening of the slide rail 5 due to factors such as bumps.

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