Description

Technical Field

[0001] This invention relates to the field of geological exploration and new energy utilization technology, and in particular to a geological exploration and testing device for permafrost regions. Background Technology

[0002] With the increasing demand for global climate change and resource exploration, geological exploration activities in high-altitude and permafrost regions are becoming more frequent. The harsh environment of permafrost regions, characterized by low temperatures, large diurnal temperature variations, and intense freeze-thaw cycles, poses a significant challenge to the long-term and stable operation of exploration equipment.

[0003] Existing geological exploration equipment typically uses battery power or traditional single-axis solar power systems. However, in polar or high-latitude regions, the angle of sunlight varies greatly throughout the day, making it difficult for traditional fixed or single-axis tracking solar panels to maximize energy capture. More seriously, winter snow can easily cover solar panels, leading to power outages. Furthermore, in permafrost regions, ground heave and thaw settlement processes generate significant vertical displacement and horizontal vibrations. These irregular, high-intensity vibrations and impacts severely affect the working accuracy of precision detection components and the reliability of mechanical connections within the exploration equipment, thereby significantly shortening its lifespan.

[0004] Therefore, this invention proposes a geological exploration and testing device for permafrost areas to address the shortcomings of existing geological exploration equipment in permafrost areas, such as unstable power supply due to environmental influences and the susceptibility of the equipment to vibration and impact, which affects the accuracy of the tests. Summary of the Invention

[0005] In view of the problems in existing technologies, such as the instability of solar power supply devices in permafrost geological exploration and testing devices due to changes in sunlight and snow accumulation, and the impact of freeze-thaw cycles and unstable foundations on the detection accuracy and reliability of the equipment, this invention aims to provide a permafrost geological exploration and testing device with an improved structure that can effectively solve the above problems.

[0006] This invention provides a geological exploration and testing device for permafrost areas, comprising: a fixed rod, a detection element, a base, a power supply box; and an adjustment mechanism and a buffer mechanism.

[0007] The adjustment mechanism includes a fixed plate, a mounting shell, a rotating assembly, a fixed block, a rotating rod, a U-shaped block (first type), a solar panel, and an electric push rod. The rotating assembly includes a motor, a connecting shaft, a driving gear, a rotating column, and a driven gear. The buffer mechanism includes a mounting block, a U-shaped block (second type), a connecting block, a slider, a connecting column, a spring (first type), a buffer column, a spring (second type), and a mounting plate.

[0008] The detection element is bolted to one side of the fixing rod, the power supply box is fixed to the rear side of the fixing rod by a clamp, and the base is fixed to the bottom of the fixing rod.

[0009] The fixing plate of the adjustment mechanism is fixedly connected to the top of the fixing rod. The mounting shell is fixedly installed on the fixing plate. The rotating component is rotatably disposed inside the mounting shell and drives the fixing block to rotate horizontally. The rotating rod is rotatably connected inside the fixing block. The U-shaped block is fixedly connected to the rotating rod. The solar panel is fixedly connected to the U-shaped block. The electric push rod is rotatably connected to the fixing plate and the solar panel respectively. The extension and retraction of the electric push rod drives the solar panel to adjust the pitch angle around the rotating rod, thereby realizing the dual-axis attitude adjustment of the solar panel.

[0010] The mounting plate of the buffer mechanism is positioned above the mounting block. The base is fixedly connected to the top of the mounting plate, the mounting block is fixedly positioned below the mounting plate, the second U-shaped block is fixedly connected to the bottom of the mounting plate, the second U-shaped block is rotatably connected to the connecting block, the connecting block is fixedly connected to the slider, the connecting post is fixedly positioned inside the mounting block, the slider is slidably sleeved on the connecting post, the first spring is wrapped around the connecting post, the buffer post is fixedly positioned on the mounting block, the second spring is sleeved on the outer periphery of the buffer post, and the bottom of the mounting plate abuts against the top of the second spring. The structure achieves composite shock absorption and buffering by converting vertical impact force into a horizontal squeezing force on the first spring, while simultaneously utilizing the second spring to directly absorb the vertical impact.

[0011] Preferably, in the rotating assembly, the motor is fixedly connected to the driving gear via the connecting shaft, the driving gear meshes with the driven gear, the driven gear is fixedly sleeved on the outer periphery of the rotating column, the rotating column passes through the mounting shell and is rotatably connected to the mounting shell, the top of the rotating column is fixedly connected to the fixing block, and the rotating assembly provides a stable and high-torque driving force for the horizontal rotation of the solar panel through the gear transmission structure.

[0012] Preferably, the electric push rod drives the solar panel to rotate around the rotating rod via telescopic movement. Both ends of the rotating rod are rotatably connected to the inner wall of the fixed block. A U-shaped block is fixedly sleeved on the middle of the rotating rod, which serves as the pitch axis of the solar panel. In the buffer mechanism, the mounting block has an internal mounting groove. The connecting column is horizontally fixedly installed within the mounting groove. The slider slides along the length of the connecting column. A spring is located between the slider and the inner wall of the mounting groove. When an external impact causes the mounting plate to press down, the linkage mechanism converts the impact direction and buffers the impact.

[0013] Preferably, when the mounting plate moves downward under the pressure of the base, the second U-shaped block pushes the slider to slide on the connecting post through the connecting block and compresses the first spring, thereby absorbing the impact energy. The buffer post is vertically fixed to the top of the mounting block, one end of the second spring abuts against the mounting block, and the other end abuts against the mounting plate. The bottom of the mounting plate has a guide hole that mates with the buffer post. The second spring provides elastic support to the mounting plate in the vertical direction, directly absorbing vertical impacts.

[0014] Preferably, spring one and spring two work together, with spring one absorbing and buffering energy through a connecting rod transmission, and spring two absorbing and buffering energy through vertical direct pressure, forming a dual protection mechanism. The detection element is fixed to the bracket on the side wall of the fixed rod by bolts, and the power supply box is fixed to the side of the fixed rod away from the detection element by clamps, so as to optimize the counterweight and installation reliability of the device.

[0015] The present invention has the following beneficial effects: 1. This invention, by setting up an adjustment mechanism, uses a rotating component in conjunction with an electric push rod to achieve bidirectional adjustment of the horizontal rotation and pitch angle of the solar panel. This solves the problem in the prior art that solar power supply devices are difficult to adapt to changes in the angle of sunlight and are easily blocked by snow, leading to interruption of energy supply. It achieves the technical effect of actively tracking sunlight all day long to improve photoelectric conversion efficiency, and by adjusting the tilt angle to slide off the snow, it ensures the long-term stable operation of the equipment in the field.

[0016] 2. This invention, by setting up a buffer mechanism, uses a linkage assembly to convert the vertical impact force into the horizontal sliding of the slider and squeeze the first spring, while cooperating with the direct vertical support of the second spring. This solves the problem of existing detection devices damaging precision instruments due to severe vibrations caused by ground subsidence or frost heave in frozen soil areas. It achieves the technical effect of efficiently dissipating vibration energy through the synergistic action of the dual springs, greatly reducing the interference of impact on the detection elements, thereby improving detection accuracy and equipment lifespan.

[0017] 3. This invention solves the problem in the prior art where a single shaft connection is prone to loosening or insufficient torque leading to rotational jamming in strong winds in the field by using a motor-driven gear meshing transmission in the rotating component. It achieves the effect of compact transmission structure, large torque output and stable operation, and further enhances the wind resistance and mechanical stability of the device under harsh weather conditions.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Example: Reference Figures 1 to 4 This invention provides a geological exploration and testing device for permafrost regions, which aims to solve the problems of unstable solar power supply caused by changes in the angle of sunlight and snow cover when existing geological exploration equipment is used in the field, as well as the impact of vibration and shock on the equipment caused by environmental factors such as freeze-thaw cycles and unstable foundations, which affect the lifespan and detection accuracy of the equipment.

[0022] The overall structure of the geological exploration and testing device for permafrost areas mainly includes a fixed rod 1, a detection element 2, a base 3, a power supply box 4, an adjustment mechanism 5, and a buffer mechanism 6. The fixed rod 1 serves as the main support frame of the device and is made of low-temperature resistant and high-strength metal. The detection element 2 is fixedly connected to one side of the fixed rod 1 by bolts. The detection element 2 is equipped with appropriate geological sensors or probes according to actual exploration needs to collect geological data of the permafrost area. The power supply box 4 is fixedly connected to the rear side of the fixed rod 1 away from the detection element 2 by clamps. The power supply box 4 integrates a battery pack and a control unit to store electrical energy and provide power support for the detection element 2 and the electrical components of the entire device.

[0023] A base 3 is fixedly connected to the bottom of the fixed rod 1. The base 3 serves as a connection interface and is assembled with the buffer mechanism 6 below. Specifically, the base 3 is fixedly connected to the top of the mounting plate 69 of the buffer mechanism 6. The device is installed in contact with the ground through the buffer mechanism 6. The buffer mechanism 6 absorbs and dissipates irregular vibrations from the ground, thereby protecting the precision instruments on the fixed rod 1 from rigid impacts. An adjustment mechanism 5 is fixedly connected to the top of the fixed rod 1. The adjustment mechanism 5 serves as the top energy acquisition and attitude adjustment platform, integrating a solar power generation component and a dual-axis drive component. It can adjust the horizontal rotation and vertical pitch angle of the solar panel according to the light conditions and the snow accumulation in the environment, ensuring that the device can maintain efficient energy supply even in harsh environments without human intervention.

[0024] The adjustment mechanism 5 is mainly used to realize the horizontal rotation and pitch adjustment of the solar panel 57. The fixed plate 51 is fixedly connected to the top of the fixed rod 1 by bolts, and the mounting shell 52 is fixedly installed on the fixed plate 51 to accommodate the rotating component 53. The rotating component 53 includes a motor 531, a connecting shaft 532, a drive gear 533, a rotating column 534, and a driven gear 535. The motor 531 is fixedly connected inside the mounting shell 52. The output shaft of the motor 531 is fixedly connected to the drive gear 533 through the connecting shaft 532. The drive gear 533 meshes with the driven gear 535 for transmission. The driven gear 535 is fixedly sleeved on the outer circumference of the rotating column 534. The rotating column 534 passes through the mounting shell 52 and forms a rotatable connection with the mounting shell 52. The top of the rotating column 534 is fixedly connected to the fixed block 54, thereby realizing that the motor 531 drives the rotating component 53, causing the fixed block 54 to rotate horizontally around the central axis of the rotating column 534.

[0025] A rotating rod 55 is rotatably connected inside the fixed block 54. Both ends of the rotating rod 55 are rotatably connected to the inner wall of the fixed block 54. The rotating rod 55 serves as a pivot for pitch adjustment. A U-shaped block 56 is fixedly fitted into the middle of the rotating rod 55, and solar panels 57 are fixedly connected to the two ends of the U-shaped block 56. There are two electric push rods 58. The two ends of the electric push rods 58 are rotatably connected to the side of the fixed plate 51 and the bottom of the solar panel 57 respectively via pivots. Through their extension and retraction, the electric push rods 58 drive the solar panel 57 to adjust its pitch angle around the rotating rods 55. This dual-axis adjustment structure ensures that the solar panel 57 can receive sunlight to the maximum extent and can actively adjust its angle to avoid being blocked by snow.

[0026] The buffer mechanism 6 is mainly used to absorb the vertical impact and vibration transmitted from the ground to the base 3. The base 3 is fixedly connected to the top of the mounting plate 69, and the mounting block 61 serves as a base and is fixedly set below the mounting plate 69. The buffer mechanism 6 is provided with two sets of shock absorption components. One set is a lateral linkage type shock absorption structure, including a second U-shaped block 62, a connecting block 63, a slider 64, a connecting column 65, and a first spring 66; the other set is a vertical direct pressure type shock absorption structure, including a buffer column 67 and a second spring 68.

[0027] Among them, U-shaped block 62 is fixedly connected to the bottom of mounting plate 69, and U-shaped block 62 and connecting block 63 form a rotatable connection. Connecting block 63 is fixedly connected to slider 64. Mounting block 61 has an installation groove inside, connecting post 65 is horizontally fixedly installed in the installation groove, slider 64 is slidably sleeved on connecting post 65, and spring 66 is sleeved on connecting post 65, located between slider 64 and the inner wall of the installation groove. When mounting plate 69 is subjected to pressure and moves downward, U-shaped block 62 converts vertical pressure into horizontal thrust through connecting block 63, pushing slider 64 to slide on connecting post 65 and squeeze spring 66, realizing horizontal absorption and dissipation of energy.

[0028] Motor 531 is fixedly connected to drive gear 533 via connecting shaft 532. Drive gear 533 meshes with driven gear 535, which is fixedly sleeved on the outer circumference of rotating column 534. Rotating column 534 passes through mounting shell 52 and is rotatably connected to it. Fixed block 54 is fixedly connected to the top of rotating column 534. After motor 531 starts, it drives drive gear 533 and driven gear 535 to rotate, thereby driving rotating column 534 to rotate, ultimately achieving horizontal rotation of solar panel 57. This gear transmission structure can provide sufficient... Torque is used to ensure that the solar panel 57 can still rotate stably under wind load conditions in the field. The two ends of the electric push rod 58 are rotatably connected to the bottom of the fixed plate 51 and the solar panel 57 respectively through the rotating shaft. The two ends of the rotating rod 55 are rotatably connected to the inner wall of the fixed block 54. The rotating rod 55 serves as the pitch axis of the solar panel 57. When the electric push rod 58 extends or retracts, it drives the solar panel 57 to rotate around the rotating rod 55, thereby adjusting the tilt angle of the solar panel 57 to adapt to the light angle of different latitudes and avoid the obstruction of sunlight by snow accumulation.

[0029] The mounting block 61 has an internal mounting groove. The connecting post 65 is horizontally fixed in the mounting groove. The slider 64 slides along the length of the connecting post 65. Spring 66 is wrapped around the connecting post 65 and located between the slider 64 and the inner wall of the mounting groove. When the mounting plate 69 moves downward, the U-shaped block 62 converts the vertical pressure into a horizontal thrust through the connecting block 63, pushing the slider 64 to squeeze the spring 66. The elastic deformation of the spring 66 absorbs part of the impact energy. The buffer post 67 is vertically fixed to the top of the mounting block 61. Spring 68 is sleeved on the outer periphery of the buffer post 67. The bottom of the mounting plate 69 has a guide hole that mates with the buffer post 67. The bottom of the mounting plate 69 directly abuts against the top of the spring 68. One end of the spring 68... The first end abuts against the mounting block 61, and the other end abuts against the mounting plate 69. Spring 2 68 provides elastic support for the mounting plate 69 in the vertical direction. When the mounting plate 69 is pressed downward, spring 2 68 is pressed along the buffer column 67, directly absorbing the impact energy in the vertical direction, forming a composite buffer with spring 1 66. The detection element 2 is fixed to the bracket on the side wall of the fixing rod 1 by bolts. The bracket is made of lightweight and high-strength material to minimize the impact on the detection element 2. The power supply box 4 is fixed to the side of the fixing rod 1 away from the detection element 2 by clamps. The clamps can provide reliable clamping force to ensure that the power supply box 4 will not loosen or fall off in the vibration environment. This installation method makes the counterweight of the equipment more reasonable and enhances the overall stability of the device.

[0030] The implementation principle of this application embodiment is as follows: The frozen soil geological exploration and detection device consists of a fixed rod 1, with a detection element 2 installed on the left side of the fixed rod 1 to conduct geological exploration and detection in the frozen soil area. The bottom of the fixed rod 1 has a base 3, which is installed on the mounting plate 69 of the buffer mechanism 6 to reduce vibration of the device and prevent it from being damaged by impact. A power supply box 4 is installed on the rear side of the fixed rod 1 to provide power, while the top of the fixed rod 1 is equipped with a buffer mechanism 6 to adjust the angle of the solar panel 57, actively aligning it with the sun and improving the stability of power supply.

[0031] When the permafrost geological exploration and testing device is powered by the power supply box 4, the detection element 2 performs geological exploration and testing in the permafrost region. The solar panel 57 provides most of the power. When the fixed solar panel 57's solar absorption efficiency is low, the angle of the solar panel 57 needs to be adjusted. An adjustment mechanism 5 is used to adjust the angle of the solar panel 57. This adjustment mechanism is installed via a fixed rod 1 and a fixed plate 51. The mounting shell 52 on the fixed plate 51 protects the rotating component 53. The rotating component 53 within the mounting shell 52 rotates the solar panel 57. The motor 531 within the mounting shell 52 provides power, causing the motor 531 to drive the connecting shaft 532 to rotate. The connecting shaft 532 is fixed to the drive gear 533, causing the drive gear 533 to rotate. This is then connected to the mounting shell 52 via a rotating column 534, which is fitted with a driven gear 5. 35. The driven gear 535 meshes with the driving gear 533, causing the driving gear 533 to drive the driven gear 535, which in turn rotates the rotating column 534. The rotating column 534 is fixed to the fixed block 54, causing the rotating column 534 to drive the fixed block 54 to rotate, thus rotating the solar panel 57. The rotation function can turn the solar panel to a sunny area without snow accumulation or obstruction, avoiding insufficient power supply caused by long-term snow blockage. Then, the rotating rod 55 inside the fixed block 54 rotates. 55 and U-shaped block 56 are fixedly connected, U-shaped block 56 is fixedly connected to solar panel 57, and electric push rod 58 connects fixed plate 51 and solar panel 57. Solar panel 57 is connected to two electric push rods 58, which extend and retract to rotate solar panel 57. The angle adjustment can actively avoid shading or face the sun, improving power supply stability. Solar panel 57 drives U-shaped block 56 to rotate within fixed block 54 through rotating rod 55 to adjust the angle.

[0032] When the geological survey and testing device in the permafrost region encounters external vibration, the buffer mechanism 6 comes into play. It is connected to the base 3 and the mounting plate 69. The base 3 of the fixed rod 1 is pressed down, and then transmitted to the slider 64 through the rotational connection of the U-shaped block 62 and the connecting block 63. The U-shaped block 62 and the mounting plate 69 are fixedly connected. The connecting column 65 is installed in the mounting groove in the mounting block 61. The slider 64 is fitted with a spring 66, which makes the slider 64 slide and compress the spring 66 to slide in the connecting column 65. At the same time, the base 3 of the fixed rod 1 is pressed down, and the mounting plate 69 abuts against the top of the buffer column 67, so that the spring 68 fitted on the outer periphery of the buffer column 67 is compressed. Through the coordinated compression and rebound of the spring 66 and the spring 68, the vibration energy is effectively absorbed and dissipated, protecting the device on the fixed rod 1 from impact damage.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
