Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a geophysical exploration device for fractures in hydrogeological environments. Background Technology

[0002] There are countless geological fissures in my country. Most of these fissures are located in mountainous areas or earthquake-prone zones. Some of these fissures are in hydrogeological environments, which are underground hydrogeological environments. In such environments, the fissures are located below groundwater, and the fissures above them are mostly moist and damp. Researchers need to take samples of the soil and rocks in the fissures and analyze their composition. Currently, most sampling is done by drilling and core sampling with geological drills.

[0003] Chinese patent document CN116735248B discloses a fracture geophysical exploration equipment for hydrogeological and annular geology, relating to the field of fracture geophysical exploration technology. The equipment includes a main outer casing, with side outer casings fixedly mounted on both sides. A support frame is fixedly welded to one side of the lower end of the main outer casing. A hydraulic column is fixedly mounted in the middle of the lower end of the main outer casing, with a pressure-type connecting column connected to the lower end of the hydraulic column. A pressure-type connecting column is welded to the lower end of the pressure-type connecting column. This invention achieves sampling of the rock wall within the fracture by preventing a small piece of rock from detaching and falling into the lower placement box during the impact process. The rock impact component can sample a small area of ​​the rock wall, generating a small vibration amplitude that does not cause large-scale collapse of the fracture.

[0004] However, in actual use, the device is inconvenient for collecting soil, and the soil is easy to spill out, making the device difficult to operate. In addition, stones can easily cause injury to the operator during actual use, making the device relatively unsafe. Summary of the Invention

[0005] The main objective of this invention is to provide a geophysical exploration device for fractures in hydrogeology and environmental geology, which can effectively solve the problems of inconvenient operation and relatively low safety of the device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fracture geophysical exploration device for hydrogeological environment includes a device base, with support rods fixed at the four corners of the upper end of the device base. A first mounting bracket is slidably mounted on the outer surface of a plurality of support rods. A limiting block for limiting the first mounting bracket is fixed at the upper end of each of the support rods. A plurality of return springs sleeved on the outer surface of the support rods are fixed between the first mounting bracket and the device base. An operating handle is fixed at the upper end of the first mounting bracket. A first collecting component is also provided at the lower end of the first mounting bracket. A second collecting component is also provided at the upper end of the device base. The first collecting component includes a mounting plate fixed to the lower end of the first mounting bracket. An internal gear ring is rotatably mounted on the lower end of the mounting plate. A mounting tube is fixed to the lower end of the internal gear ring. A hollow drill rod is fixed to the lower end of the mounting tube. The drill rod passes downward through the device base and is threadedly connected to the device base. A first transmission gear is also rotatably mounted in the middle of the lower end of the mounting plate. A first auger that fits against the inner wall of the drill rod is fixed to the lower end of the first transmission gear. A second gear that meshes with the internal gear ring and the first transmission gear is also rotatably mounted on the lower end of the mounting plate.

[0007] Preferably, a sealing plate is fixed to the upper part of the inner surface of the mounting tube, and multiple through grooves are also provided on the lower part of the inner surface of the mounting tube.

[0008] Preferably, the lower end of the mounting plate is also fixed with a discharge pipe with openings at the top and bottom, the outer surface of the discharge pipe is provided with a discharge groove, and the outer surface of the mounting pipe is also fixed with a scraper that fits against the inner wall of the discharge pipe.

[0009] Preferably, the upper end of the mounting plate is further provided with a limiting rod for limiting the internal gear ring.

[0010] Preferably, the second collecting component includes a plurality of second mounting brackets fixed to the upper end of the device base, a friction wheel rotatably mounted on the lower end of the second mounting brackets in contact with the drill rod, a second auger fixed to the lower end, a plurality of through holes adapted to the second auger being opened on the upper end of the device base, a receiving tube being fixed to the upper end of the device base, a discharge gate being opened on the outer surface of the receiving tube, and a suction cup being fixed to the lower end of the device base.

[0011] Preferably, the suction cup communicates with the interior of the plurality of through holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts the design of the first collection component. Through the cooperation between the second gear, the internal gear ring, and the first transmission gear, the device can collect the drilled soil while drilling into the land, which facilitates the operation of the device. At the same time, through the cooperation between the discharge chute and the scraper, it can prevent the material from being spilled to other places, thus preventing the operator from cleaning up the impurities, which also facilitates the operation of the device.

[0013] This invention utilizes the design of the first spiral auger and the through groove to allow impurities on the ground to be discharged during material extraction, thereby improving the accuracy of the device's detection.

[0014] This invention employs a second collection component design, which uses a suction cup to collect broken stones and stone powder during drilling. Then, through the interaction between the drill rod and the friction wheel, the second auger transports the material upward and collects it in the collection tube. This can prevent stones from injuring operators and also reduce environmental pollution. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0018] like Figure 1 As shown, a fracture geophysical exploration device for hydrogeological environment includes a device base 1. Support rods 11 are fixed at the four corners of the upper end of the device base 1. A first mounting bracket 12 is slidably mounted on the outer surface of multiple support rods 11. The multiple support rods 11 support the first mounting bracket 12, allowing it to move upwards or downwards. Limiting blocks 13 are fixed at the upper ends of the multiple support rods 11 to limit the movement of the first mounting bracket 12. The limiting blocks 13 prevent the first mounting bracket 12 from detaching from the support rods 11, thus affecting the normal operation of the device. Multiple return springs 14, sleeved on the outer surface of the support rods 11, are fixed between the first mounting bracket 12 and the device base 1. The multiple return springs 14 facilitate the reset of the first mounting bracket 12. An operating handle 15 is fixed at the upper end of the first mounting bracket 12, and a first collection assembly 2 is also provided at the lower end of the first mounting bracket 12.

[0019] like Figure 2 - Figure 8 As shown, the first collecting component 2 includes a mounting plate 21 fixed to the lower end of the first mounting bracket 12. An internal gear ring 22 is rotatably mounted on the lower end of the mounting plate 21. A mounting tube 23 is fixed to the lower end of the internal gear ring 22. A hollow drill rod 26 is fixed to the lower end of the mounting tube 23. The drill rod 26 passes downward through the device base 1 and is threadedly connected to the device base 1. The drill rod 26 can rotate when it moves downward relative to the device base 1 due to the threaded connection between the mounting plate 21 and the internal gear ring 22. At the same time, due to the rotatable connection between the mounting plate 21 and the internal gear ring 22, when the mounting plate 21 moves downward relative to the device base 1, the drill rod 26 will also rotate due to the threaded connection between the device base 1 and the drill rod 26.

[0020] In addition, a first transmission gear 27 is rotatably mounted on the lower center of the mounting plate 21. A first spiral auger 28, which is in contact with the inner wall of the drill rod 26, is fixed to the lower end of the first transmission gear 27. This allows the first spiral auger 28 to transport the material inside the drill rod 26 upwards or downwards when it rotates. A second gear 29, which meshes with the internal gear ring 22 and the first transmission gear 27, is also rotatably mounted on the lower end of the mounting plate 21. Due to the design of the second gear 29 meshing with the internal gear ring 22 and the first transmission gear 27, when the internal gear ring 22 rotates, it causes the first transmission gear 27 to rotate in the opposite direction relative to the internal gear ring 22. This further causes the first spiral auger 28 to rotate in the opposite direction relative to the drill rod 26, thereby allowing the first spiral auger 28 to transport the material inside the drill rod 26 upwards or downwards.

[0021] Furthermore, to facilitate the discharge of material from inside the drill pipe 26, such as... Figure 3 As shown, a sealing plate 24 is fixed on the upper part of the inner surface of the mounting tube 23. The sealing plate 24 can prevent the material conveyed upward by the first spiral auger 28 from entering between the internal gear ring 22 and the first transmission gear 27, thereby affecting the normal operation of the device. Multiple through slots 25 are also provided on the lower part of the inner surface of the mounting tube 23, so that the material conveyed by the first spiral auger 28 can be discharged through the through slots 25. This further enables the device to discharge impurities above the gaps during use, thereby improving the accuracy of the device's detection.

[0022] In addition, a discharge pipe 31 with openings at the top and bottom is fixed to the lower end of the mounting plate 21. A discharge groove 32 is provided on the outer surface of the discharge pipe 31. The discharge groove 32 is used to discharge the material inside the discharge pipe 31. A scraper 33 that fits against the inner wall of the discharge pipe 31 is also fixed to the outer surface of the mounting pipe 23. Due to the design of the mounting pipe 23 and the scraper 33 being fixedly connected, the scraper 33 can drive the material in the discharge pipe 31 to move when it rotates, so that the material in the discharge pipe 31 can be discharged from the discharge groove 32. If the discharge pipe 31 is not provided and the material is directly discharged from the through groove 25 to the outside, the material will spill out due to the rotation of the drill rod 26 relative to the mounting plate 21, making it inconvenient to collect impurities. Operators need to clean up the impurities. To facilitate the collection of impurities, such as Figure 1 As shown, a storage box that matches the discharge trough 32 is also fixed at the lower end of the mounting plate 21, so that impurities coming out of the discharge trough 32 can be stored in the storage box.

[0023] Meanwhile, the upper end of the mounting plate 21 is also provided with a limiting rod 34 for limiting the internal gear ring 22. When the limiting rod 34 limits the internal gear ring 22, the internal gear ring 22 will not be able to rotate, so that the drill rod 26 and the first spiral auger 28 will not be able to rotate. At the same time, the design of the first spiral auger 28 can also prevent the material inside the drill rod 26 from falling out.

[0024] The specific implementation of this embodiment is as follows: When using the device, first place the device at the place where sampling is required, and align the drill rod 26 with the crack. Then push the operating handle 15 towards the side closer to the device base 1. When the operating handle 15 moves towards the side closer to the device base 1, the first mounting bracket 12 will also move towards the side closer to the device base 1. At the same time, due to the threaded connection between the device base 1 and the drill rod 26, the drill rod 26 will rotate when moving towards the side of the crack, thereby enabling drilling operations at the crack. When the drill rod 26 rotates, the meshing between the second gear 29, the internal gear ring 22, and the first transmission gear 27 causes the first transmission gear 27 to rotate in the opposite direction to the internal gear ring 22. This further enables the first auger 28 to transport the material inside the drill rod 26 upwards. When the material comes into contact with the bottom surface of the sealing plate 24, it can be discharged through the through groove 25 and then enter the discharge pipe 31. At the same time, due to the fixed connection between the discharge pipe 31 and the mounting plate 21, the scraper 33 scrapes the material in the discharge pipe 31 when it rotates, allowing the material to be discharged from the discharge trough 32. The material can then be stored in the storage box. Simultaneously, when the mounting plate 21 moves away from the device base 1, the first auger 28 and the drill rod 26 will rotate in opposite directions, further allowing the material inside the drill rod 26 to exit from below. After the device completes sampling, the limiting rod 34 is used to limit the internal gear ring 22 to prevent the material inside the drill rod 26 from falling back into the crack when the internal gear ring 22 rotates in the opposite direction. This also facilitates the removal of the device from the crack and the collection of the material inside the drill rod 26. Then, the operator uses other instruments to test the collected material, thereby achieving the purpose of exploration. Example 2

[0025] This embodiment is a further improvement on the second collection component 4 based on the first embodiment, enabling the device to drill holes and explore rocks during use.

[0026] like Figure 9 - Figure 10 As shown, the second collection component 4 includes multiple second mounting brackets 41 fixed to the upper end of the device base 1. A friction wheel 42 that contacts the drill rod 26 is rotatably mounted on the lower end of the second mounting bracket 41. Through the mutual cooperation between the friction wheel 42 and the drill rod 26, the drill rod 26 can drive the friction wheel 42 to rotate when it rotates. A second auger 43 is fixed at the lower end. Multiple through holes 44 adapted to the second auger 43 are opened at the upper end of the device base 1. Due to the design of the through holes 44 and the second auger 43 cooperating with each other, the through holes 44 can transfer materials up.

[0027] Specifically, a collection tube 45 is fixed to the upper end of the device base 1. The collection tube 45 is used to collect materials. A discharge door 46 is opened on the outer surface of the collection tube 45. The discharge door 46 is existing technology and is mainly used to remove materials. A suction cup 47 is fixed to the lower end of the device base 1. When the device is in use, it can prevent stones and stone powder broken by the drill rod 26 from splashing. It not only makes it convenient to collect stones and stone powder, but also prevents stones from causing injury to operators. At the same time, stones and stone powder will accumulate in the suction cup 47. The suction cup 47 is connected to the interior of multiple through holes 44, which facilitates the second spiral auger 43 to transport stones and stone powder upward.

[0028] Furthermore, when the device is drilling or exploring rocks, the operating handle 15 is insufficient for drilling operations. Therefore, the operating handle 15 needs to be removed and replaced with a drive motor. The drive motor is fixedly installed on the upper end of the operating handle 15, and the output end of the drive motor is fixedly connected to the first transmission gear 27. When the output end of the drive motor rotates, it can drive the first transmission gear 27 to rotate. Then, through the mutual cooperation between the first transmission gear 27, the second gear 29, and the internal gear ring 22, the internal gear ring 22 rotates in the opposite direction. At the same time, the drill rod 26 moves downward as it rotates, allowing the drill rod 26 to drill or explore rocks. Due to the meshing design of the second gear 29 with the first transmission gear 27 and the internal gear ring 22, the first auger 28 rotates in the opposite direction relative to the drill rod 26, allowing the rocks drilled by the drill rod 26 to be transported upward by the first auger 28 and stored in the drill rod 26.

[0029] The specific implementation of this embodiment is as follows: When in use, the device is first placed on the rock to be explored, and then the rock is drilled by rotating the drill rod 26. At the same time, through the threaded connection between the drill rod 26 and the device base 1, the drill rod 26 will also move downward when it is rotated, thereby drilling the rock deeper. When the drill rod 26 drills into the rock, the suction cup 47 collects the broken rocks and stone powder. Simultaneously, the interaction between the drill rod 26 and the friction wheel 42 drives the second auger 43 to rotate. The second auger 43 transports the stone powder and broken rocks from the suction cup 47 upwards, allowing the material to be stored in the collection tube 45. After drilling is complete, the discharge door 46 is opened to remove the material. Since some material is also stored inside the drill rod 26, the inner gear ring 22 is fixed by the limiting rod 34. After the drill rod 26 is removed from the hole, the limiting rod 34 is not used to limit the inner gear ring 22. Then, the drive motor is controlled to rotate in the opposite direction, causing the first auger 28 to rotate in the opposite direction, thus discharging the material stored inside the drill rod 26.

[0030] Then, the operators use other instruments to test the collected materials, thereby achieving the purpose of exploration.

[0031] It should be noted that the specific installation methods, circuit connection methods, and control methods of the spiral auger, drill rod 26, and suction cup 47 in this invention are all conventional designs, and will not be described in detail in this invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
