Description

Technical Field

[0001] The present invention relates to the technical field of radio wave monitoring, and particularly relates to a portable slope monitoring radar for geological exploration. Background Art

[0002] Geological exploration is to conduct on-site investigations and measurements of the topography, stratigraphic lithology, geological structure, etc. of the construction area, and draw an engineering geological map. There are various landforms during the geological exploration process. Especially during the slope exploration process, the geological conditions of the slope are often complex and changeable (such as uneven rock and soil masses, developed fissures, active groundwater, etc.). Traditional slope exploration methods (such as manual inspections, borehole sampling, sensor monitoring) have low spatial resolution, small coverage, and are difficult to monitor in real time. Therefore, a slope monitoring radar needs to be used. It can penetrate the ground surface, detect internal structures and hidden dangers, provide more comprehensive information for exploration, and through the radar wave reflection signal, it can identify hidden dangers such as the unevenness, cavities, and weak interlayers of the slope rock and soil masses; most of the commonly used radar detectors are divided into box-type and mobile types that cooperate with a trolley. When the traditional box-type radar detector is used, it is placed in the detection area for use. The position of the monitoring radar placed on the slope is relatively fixed, and it is difficult to adjust the position. When the detection area is large, it needs to be manually carried repeatedly, and its portability is not good, so it is impossible to accurately explore some key areas found temporarily in time, affecting the rapid response of the radar detector to geological exploration. Summary of the Invention

[0003] The purpose of the present invention is to provide a portable slope monitoring radar for geological exploration to solve the above deficiencies in the technology.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A portable slope monitoring radar for geological exploration, including a radar instrument and a bottom support. A portable cavity for placing and taking out the radar instrument is opened at the top of the bottom support. A portable moving and placing component is provided at the bottom of the bottom support. The portable moving and placing component includes a moving rod support fixedly connected to the bottom of the bottom support and a rotating column rotatably connected in the portable cavity. The moving rod support is used to place the radar instrument on the slope or hold it for carrying to improve the response ability of the radar instrument. The rotating column is used to drive the radar instrument to move in the portable cavity and increase the exploration range of the radar instrument. A number of limiting components for balancing and supporting the radar instrument during movement are provided inside the portable cavity. A position blocking component for driving the limiting components to move along a specific trajectory outside the radar instrument is arranged outside the bottom support.

[0005] Preferably, a servo motor is provided at the top end of the bottom support, and the servo motor is used to drive the rotating column to rotate. One end of the radar instrument close to the rotating column is fixedly connected with an adapter cone seat. Two displacement slots and two shifting slots for guiding the adapter cone seat to move are respectively formed in the outer part of the rotating column. The two shifting slots are symmetrically arranged outside the rotating column, and the two displacement slots are arranged in an arc structure. A fixed seat for the adapter cone seat to move up and down is fixedly connected inside the portable cavity.

[0006] Preferably, a sliding groove is formed on one side of the fixed seat close to the adapter cone seat. One side of the adapter cone seat is fixedly connected with a sliding block, and the sliding block is slidably connected inside the sliding groove. The bottom end of the sliding block is fixedly connected with an extension rod, and the bottom end of the extension rod penetrates through the sliding groove. A return spring is jointly connected between the sliding block and the sliding groove, and the return spring is sleeved outside the extension rod.

[0007] Preferably, the limiting component includes a limiting bracket installed in the portable cavity. A friction roller is movably connected inside the limiting bracket, and the friction roller is used to move the radar instrument along a predetermined path inside the portable cavity. Connecting shells are installed at one ends of the friction roller corresponding to the limiting bracket, and connecting columns are jointly connected between the connecting shells and the friction roller.

[0008] Preferably, a stabilizing frame is fixedly connected inside the connecting shell. A barbed gear is jointly connected between the stabilizing frame and the connecting column, and the barbed gear is used to drive the friction roller to always rotate in one direction along one end of the connecting shell. A barbed claw is movably connected to one side of the stabilizing frame close to the barbed gear, and the end of the barbed claw abuts against the outside of the barbed gear. A connecting column is installed on one side of the stabilizing frame close to the barbed claw, and an extension spring is jointly connected between one end of the connecting column and one side of the barbed claw.

[0009] Preferably, the position blocking component includes two centering grooves symmetrically formed at the top end of the bottom support. Two position blocking frames are movably connected inside the two centering grooves. Two guiding grooves communicating with the inside of the two centering grooves are symmetrically formed inside the portable cavity. A position blocking plate is jointly connected between the limiting bracket and the position blocking frame, and the position blocking plate is slidably connected inside the guiding groove.

[0010] Preferably, a centering frame is fixedly connected to one side of the bottom support. A guide rod cooperating with the two position blocking frames is rotatably connected to one side of the bottom support. A rotating motor is fixedly connected to one side of the centering frame close to the guide rod, and the rotating motor is used to drive the guide rod to rotate.

[0011] Preferably, the two position blocking frames are slid out along the two centering grooves by the rotation of the guide rod, and the sliding-out parts of the two position blocking frames are located on both sides of the radar instrument. The two position blocking frames are arranged in an L-shaped structure.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are: Through the settings of the portable placement component, the bottom support and the radar instrument, the radar instrument moves upward to the maximum position inside the portable cavity, which is used to synchronously adjust the monitoring range of the radar instrument and store the radar instrument in the portable cavity. When conducting slope exploration, it can not only be stably placed in the exploration area for exploration, but also be held to detect key areas found temporarily, and can be immediately put into use to quickly monitor the changing area, obtain the latest geological information in a timely manner, improve the rapid response of the radar instrument to geological exploration, and facilitate quickly understanding the stability of the slope; Through the settings of the rotating column, the connecting conical seat, the transposition groove, the displacement groove and the radar instrument, the connecting conical seat drives the radar instrument to move upward along the inside of the portable cavity under the rotation of the rotating column, and then changes from upward movement to downward movement, and reciprocates in this way. This is not only used to increase the monitoring range of the radar instrument for the slope, enabling the device to be flexibly used under different terrains and operating conditions, improving the applicability of the device, but also can store the radar instrument after the detection is completed for easy carrying of the radar instrument; Through the settings of the rotating column, the connecting conical seat, the displacement groove and the transposition groove, during the process of the rotating column rotating to push the connecting conical seat to move up and down, the rotational movement has good stability, and the transposition groove and the displacement groove can play a certain buffering and guiding role in the movement of the connecting conical seat, preventing the radar instrument from being damaged due to the large impact force generated by the direct vertical lifting during the up and down movement and storage method, and conveniently adjusting the position and posture of the radar instrument, improving the reliability and service life of the device; Through the settings of the fixed seat, the return spring, the transposition groove, the displacement groove and the connecting conical seat, there is a neutral area between the connecting conical seat and the transposition groove and the displacement groove. Then, the elastic force of the return spring itself gives the connecting conical seat a reset movement along the transposition groove. When the radar instrument needs to be used again, just move the connecting conical seat to the neutral position, and the return spring will automatically return the connecting conical seat and the radar instrument accurately to the preset working position, ensuring the normal operation and measurement accuracy of the radar, and is particularly suitable for some geological exploration tasks that require rapid response; Through the settings of the limiting component, the portable cavity and the radar instrument, it can play a guiding role in the downward movement of the radar instrument, ensuring that the radar instrument always slides along the predetermined path during the movement, ensuring that the radar instrument can be accurately stored in the designated position, and improving the operation stability of the device; Through the settings of the friction roller, the thorn claw, the thorn gear and the thorn claw, it is used to prevent the thorn gear from rotating counterclockwise, so that the friction roller cannot rotate inside the limiting support. At this time, the contact between the friction roller and the surface of the radar instrument becomes static friction, which can provide a greater supporting force. This frictional force can control the moving speed of the radar instrument when moving upward, prevent the radar instrument from colliding due to too fast movement, and also avoid affecting the work efficiency due to too slow movement, ensuring that the radar instrument accurately returns to the working position and improving the accuracy of the monitoring data; Through the settings of the friction roller, the radar detector, the portable cavity and the position blocking assembly, the present invention enables the friction roller to contact different external positions of the upwardly moving radar detector, providing a more stable guiding effect for the radar detector. Since the friction roller maintains relative movement with the moving radar detector, a relatively fixed contact relationship is formed between it and the surface of the radar, just like an orbit, which can strictly limit the moving path of the radar detector, enabling the radar detector to only rise smoothly along a specific direction of the portable cavity, avoiding deviation or shaking during the rising process, reducing unnecessary interference, ensuring that the radar detector accurately returns to the working position, and improving the accuracy of slope monitoring.

[0016] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] The present invention provides a portable geological exploration slope monitoring radar as shown in Figure 1 and Figure 2 , which includes a radar device 1 and a bottom support 11. A portable cavity 12 for placing and removing the radar device 1 is provided at the top of the bottom support 11. A portable displacement and placement component 2 is provided at the bottom of the bottom support 11. The displacement and placement component 2 includes a portable rod support 21 fixedly connected to the bottom of the bottom support 11 and a rotating column 22 rotatably connected in the portable cavity 12. The portable rod support 21 is used to place the radar device 1 on the slope or hold it for carrying to improve the response ability of the radar device 1, and the rotating column 22 is used to drive the radar device 1 to move in the portable cavity 12 and increase the exploration range of the radar device 1: The structure and principle of the radar device 1 are both prior arts, so no further elaboration is made in this application; currently, during the geological slope exploration process, the process of the radar device 1 usually includes the following steps: 1. Define the monitoring target and scope (such as the entire slope or key areas) and monitoring period (such as real-time monitoring or regular monitoring); 2. Debug the radar equipment, set radar parameters (such as frequency, sampling interval, scanning mode, etc.), adjust according to the monitoring target and slope material characteristics, and perform equipment calibration to ensure the accuracy and consistency of the data; 3. Data preprocessing, removing noise (such as electromagnetic interference, environmental interference, etc.), correcting equipment errors, filtering, enhancing, and splicing the radar images to generate clear monitoring result images. Through real-time data, abnormal changes in the slope can be detected in a timely manner to warn of potential landslides.

[0018] Refer to Figure 2 , Figure 4 , Figure 5 and Figure 6As shown in the figure, a servo motor 202 is provided at the top of the bottom support 11, and the servo motor 202 is used to drive the rotation of the rotating column 22. One end of the radar device 1 close to the rotating column 22 is fixedly connected with an adapter cone seat 25. Two displacement slots 23 and two shifting slots 24 for guiding the movement of the adapter cone seat 25 are respectively formed in the outer part of the rotating column 22. The two displacement slots 23 are symmetrically arranged outside the rotating column 22, and the two shifting slots 24 are arranged in an arc structure. A fixed seat 26 for the up and down movement of the adapter cone seat 25 is fixedly connected inside the portable cavity 12. A sliding slot 201 is formed on one side of the fixed seat 26 close to the adapter cone seat 25. A sliding block 27 is fixedly connected to one side of the adapter cone seat 25, and the sliding block 27 is slidably connected inside the sliding slot 201. The bottom end of the sliding block 27 is fixedly connected with an extension rod 28, and the bottom end of the extension rod 28 penetrates through the sliding slot 201. A return spring 29 is jointly connected between the sliding block 27 and the sliding slot 201, and the return spring 29 is sleeved outside the extension rod 28; Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown in the figure, in addition, the two displacement slots 24 communicate with the two shifting slots 23 inside, and are used to realize the up and down reciprocating movement of the adapter cone seat 25 in the displacement slots 24 and the shifting slots 23; and the rotation of the rotating column 22 drives the two displacement slots 24 and the two shifting slots 23 to alternately operate with the adapter cone seat 25, so that the adapter cone seat 25 drives the radar device 1 to move upward along the inside of the portable cavity 12 under the rotation of the rotating column 22, and then changes from upward movement to downward movement, and reciprocates in this way. This is not only used to increase the monitoring range of the radar device 1 for the slope, enabling the device to be flexibly used under different terrains and operating conditions, improving the applicability of the device, but also capable of storing the radar device 1 after the detection is completed for easy carrying of the radar device 1; Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, when it is necessary to survey and monitor the geological slope, first, the movable rod holder 21 has two usage states. It can be placed near the area where the survey is required, or it can be held and moved while surveying. The servo motor 202 drives the rotating column 22 to rotate along the portable cavity 12, and then the rotating column 22 rotates to drive the two displacement grooves 24 and the two transposition grooves 23 to rotate synchronously, so that the two displacement grooves 24 and the two transposition grooves 23 maintain alternating contact with the connecting cone seat 25. At this time, the connecting cone seat 25 moves along one of the displacement grooves 24 to the inside of one of the transposition grooves 23, and then one of the displacement grooves 24 loses its resistance to the connecting cone seat 25. The return spring 29 exerts an upward force on one side of the slider 27 due to its own elastic force, so that the slider 27 moves upward along the inside of the slide groove 201, and the movement of the slider 27 drives the connecting cone seat 25 and the extension rod 28 to move upward synchronously, so that the connecting cone seat 25 moves upward along one side of the fixed seat 26 and the inside of one of the transposition grooves 23, so that the radar instrument 1 moves upward to the maximum position inside the portable chamber 12. As the rotating column 22 rotates continuously, the connecting cone seat 25 moves from the inside of one of the transposition grooves 23 to the inside of the other displacement groove 24, and then the other displacement groove 24 contacts the outside of the connecting cone seat 25 and pushes The connecting cone seat 25 moves downward along the interior of the portable cavity 12, and then the movement of the connecting cone seat 25 drives the slider 27 to move downward synchronously along the interior of the slide groove 201, so that the radar instrument 1 moves toward the interior of the portable cavity 12 under the movement of the connecting cone seat 25, which is used to synchronously adjust the monitoring range of the radar instrument 1. At the same time, in the process of the rotating column 22 rotating to push the connecting cone seat 25 to move up and down, the rotational movement has good stability, and the transposition groove 23 and the displacement groove 24 can play a certain buffering and guiding role on the movement of the connecting cone seat 25, preventing the radar instrument 1 from generating a large impact force due to direct vertical lifting when it is stored up and down. It is easy to cause damage to the detection radar instrument 1, and the position and posture of the radar instrument 1 can be easily adjusted, thereby improving the reliability and service life of the equipment. In summary, when encountering some temporarily discovered key areas, the surveyor can hold the portable rod holder 21 and drive the radar instrument 1 to move, so as to accurately survey the temporarily discovered areas; when surveying the slope, it can be stably placed in the survey area for survey, and can also be held to detect the temporarily discovered key areas, which can be put into use immediately, quickly monitor the changing areas, and obtain the latest geological information in time, thereby improving the rapid response of the radar instrument 1 to geological surveys and facilitating the rapid understanding of the stability of the slope; refer to Figure 4 、 Figure 5 and Figure 6As shown, when the connecting cone seat 25 moves in a guiding manner inside the two commutation slots 23 and the two displacement slots 24, a neutral region appears between the connecting cone seat 25 and one of the commutation slots 23 and the other displacement slot 24. Immediately, the elastic force of the return spring 29 causes the connecting cone seat 25 to move and reset along one of the commutation slots 23, so as to maintain the guiding movement between the connecting cone seat 25 and the other displacement slot 24. In this way, the radar instrument 1 is moved and reset inside the portable cavity 12. When the radar instrument 1 needs to be used again, only by moving the connecting cone seat 25 to the neutral position, the return spring 29 will automatically move the connecting cone seat 25 and the radar instrument 1 accurately back to the preset working position, ensuring the normal operation and measurement accuracy of the radar. It is especially suitable for some geological exploration tasks that require quick response. In addition, the combined design of the commutation slot 23, the displacement slot 24 and the connecting cone seat 25 makes the entire storage occupy less space in the vertical direction, because the rotation action can "fold" or "compress" the storage path to a certain extent, thus improving the portability of the device.

[0019] Reference Figure 7 、 Figure 8 、 Figure 9 And Figure 10 As shown, several limiting components 3 for supporting the radar instrument 1 in a balanced manner during movement are provided inside the portable cavity 12; the limiting component 3 includes a limiting bracket 31 installed inside the portable cavity 12. A friction roller 32 is movably connected inside the limiting bracket 31, and the friction roller 32 is used to move the radar instrument 1 along a predetermined path inside the portable cavity 12. Connecting shells 33 are installed at one end of the friction roller 32 corresponding to the limiting bracket 31. A connecting column 36 is commonly connected between the connecting shell 33 and the friction roller 32; a stabilizing frame 34 is fixedly connected inside the connecting shell 33. A thorn gear 35 is commonly connected between the stabilizing frame 34 and the connecting column 36, and the thorn gear 35 is used to drive the friction roller 32 to always rotate in one direction along one end of the connecting shell 33. A thorn claw 37 is movably connected to one side of the stabilizing frame 34 close to the thorn gear 35, and the end of the thorn claw 37 abuts against the outside of the thorn gear 35. A connecting column 38 is installed on one side of the stabilizing frame 34 close to the thorn claw 37, and an extension spring 39 is commonly connected between one end of the connecting column 38 and one side of the thorn claw 37; Reference Figure 7 、 Figure 8 、 Figure 9 And Figure 10As shown, the number of several limiting components 3 is four groups, and the four groups of limiting components 3 are respectively located at the four corners in the portable cavity 12. Moreover, each group of limiting components 3 includes two connecting shells 33. Thus, the numbers of the thorn gears 35, connecting columns 36, thorn claws 37, stabilizing frames 34, connecting columns 38 and extension springs 39 are the same as that of the connecting shells 33 and are used in a matching manner. In addition, the outside of the thorn gear 35 is formed by several spines, and they rise and fall with each other, so that the moving direction between the thorn gear 35 and the thorn claw 37 is restricted. When the thorn gear 35 rotates clockwise, the friction roller 32 contacts and rolls along the outer wall of the downward-moving radar device 1 immediately. At this time, one of the spines on the outside of the thorn gear 35 moves along the bottom of the thorn claw 37 and pushes the thorn claw 37 to move upward. And after one of the spines on the outside of the thorn gear 35 slides past the thorn claw 37, another spine on the outside of the thorn gear 35 recontacts the thorn claw 37, and so on, maintaining the clockwise rotation of the thorn gear 35. When the thorn gear 35 rotates counterclockwise, the friction roller 32 contacts the outside of the upward-moving radar device 1 immediately. At this time, the end of the thorn claw 37 abuts against two adjacent spines on the outside of the thorn gear 35 to prevent the thorn gear 35 from rotating counterclockwise; Reference Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in , Figure 6 , Figure 7 , Figure 8 and Figure 9 , when the radar device 1 moves downward in the portable cavity 12, the outside of the radar device 1 contacts the surface of the friction roller 32 due to the downward movement of the radar device 1. Immediately, the outside of the radar device 1 rolls and rubs against the surface of the friction roller 32. At this time, the friction roller 32 rolls to drive the two connecting columns 36 and the two thorn gears 35 to rotate clockwise along one side of the connecting shell 33 and the stabilizing frame 34. And one of the spines on the outside of the thorn gear 35 moves along the bottom of the thorn claw 37 and pushes the thorn claw 37 to move upward. And after one of the spines on the outside of the thorn gear 35 slides past the thorn claw 37, another spine on the outside of the thorn gear 35 recontacts the thorn claw 37, and so on. At the same time, the remaining friction rollers 32 roll and rub against the outside of the portable cavity 12 that moves downward evenly, preventing direct friction between the radar device 1 and the portable cavity 12 and providing a layer of protection for the surface of the radar device 1. And the four groups of limiting components 3 are respectively located at the four corners in the portable cavity 12, which can play a guiding role during the downward movement of the radar device 1, ensure that the radar device 1 always slides along the predetermined path during the movement, ensure that the radar device 1 can be accurately stored in the designated position, and improve the operation stability of the device; <00,00114>Reference Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, when the engagement cone seat 25 is in neutral in the transposition groove 23 and drives the radar device 1 to move upward in the portable cavity 12, contact is formed between the upward movement of the radar device 1 and the outside of the friction roller 32. Immediately, contact is formed between the friction roller 32 and the outside of the upward-moving radar device 1. At this time, the end of the thistle claw 37 abuts against two adjacent ratchet teeth on the outside of the thistle gear 35, preventing the thistle gear 35 from rotating counterclockwise and making the friction roller 32 unable to rotate within the limit bracket 31. At this time, the contact between the friction roller 32 and the surface of the radar device 1 becomes static friction, which can provide a greater supporting force. This frictional force can control the moving speed of the radar device 1 when moving upward, prevent the radar device 1 from colliding due to excessive movement speed, and also avoid affecting the working efficiency due to slow movement, ensuring that the radar device 1 accurately returns to the working position. A stable working position can ensure that the beam of the radar device 1 can accurately point to the monitoring area, reduce the monitoring error caused by position deviation, and improve the accuracy and reliability of the monitoring data. In addition, although the friction roller 32 cannot rotate and the static friction force increases, since the upward movement speed of the radar device 1 is usually slow and the material of the friction roller 32 usually has wear resistance, it will not cause excessive wear to the surface of the radar device 1 or the friction roller 32, extending the service life of the friction roller 32 and the radar device 1 while ensuring the function.

[0020] Reference Figure 2 、 Figure 10 and Figure 11 As shown, a position blocking component 4 for driving the limit support component 3 to move along a specific trajectory outside the radar device 1 is arranged outside the bottom support 11; the position blocking component 4 includes two centering grooves 45 symmetrically opened at the top end of the bottom support 11. Two position blocking frames 41 are movably connected inside the two centering grooves 45. Two guiding grooves 46 communicating with the inside of the two centering grooves 45 are symmetrically opened inside the portable cavity 12. A position blocking plate 47 is commonly connected between the limit support bracket 31 and the position blocking frame 41, and the position blocking plate 47 is slidably connected inside the guiding groove 46; Moreover, the position blocking component 4 is connected to the two groups of limit support components 3, and the number of the guiding grooves 46, the position blocking plates 47, the position blocking frames 41, and the centering grooves 45 is two; Reference Figure 2 、 Figure 10 and Figure 11 As shown, a centering frame 42 is fixedly connected to one side of the bottom support 11. A guide rod 44 cooperating with the two position blocking frames 41 is rotatably connected to one side of the bottom support 11. A rotating motor 43 is fixedly connected to the side of the centering frame 42 close to the guide rod 44, and the rotating motor 43 is used to drive the guide rod 44 to rotate; the two position blocking frames 41 slide out along the two centering grooves 45 by the rotation of the guide rod 44, and the sliding-out parts of the two position blocking frames 41 are located on both sides of the radar device 1. The two position blocking frames 41 are provided with an L-shaped structure; Reference Figure 2 、 Figure 10and Figure 11 As shown, when the radar instrument 1 moves upward in the portable cavity 12, the rotating motor 43 drives the guide rod 44 to rotate synchronously along one side of the bottom support 11. Then, the rotation of the guide rod 44 drives the two position blocking frames 41 to rotate in the two centering grooves 45. At this time, the ends of the two position blocking frames 41 move out along the inside of the two centering grooves 45, and the two position blocking frames 41 drive the two position baffle plates 47 to move synchronously in the two guide grooves 46 during the movement. Moreover, the movement of the two position baffle plates 47 drives the two friction rollers 32 to move along one side of the portable cavity 12, so that the two friction rollers 32 contact different positions on the outside of the upward-moving radar instrument 1, providing a more stable guiding effect for the radar instrument 1. Since the friction rollers 32 are in relative motion with the moving radar instrument 1, a relatively fixed contact relationship is formed between them and the radar surface, just like a track, which can strictly limit the moving path of the radar instrument 1, making the radar instrument 1 only rise smoothly along a specific direction of the portable cavity 12, avoiding deviation or shaking during the rising process, reducing unnecessary interference, ensuring that the radar instrument 1 accurately returns to the working position, and improving the accuracy of slope monitoring; in addition, after the two position blocking frames 41 slide out of the inside of the two centering grooves 45, the position blocking frames 41 and the radar instrument 1 form a cooperation after sliding out along the inside of the portable cavity 12, so that the parts of the two position blocking frames 41 that slide out of the inside of the two centering grooves 45 are located on both sides of the radar instrument 1. Thus, the two position blocking frames 41 are used to block both sides of the portable cavity 12, and then can resist the wind force on both sides of the radar instrument 1, improving the anti-interference ability of the radar instrument 1, ensuring the continuity and stability of the monitoring work, and timely and accurately detecting abnormal changes in the slope.

[0021] Working principle: When in use; Reference Figure 1 and Figure 2 As shown, when it is necessary to conduct exploration and monitoring on a geological slope, first, the movable rod support 21 has two usage states, that is, it can be placed near the area to be explored or can be held and explored while moving. Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, the servo motor 202 drives the rotation column 22 to rotate inside the portable cavity 12. Subsequently, the rotation of the rotation column 22 drives the two displacement slots 24 and the two transposition slots 23 to rotate synchronously, so that the two displacement slots 24 and the two transposition slots 23 maintain alternating contact with the connecting cone seat 25. At this time, the connecting cone seat 25 moves along one of the displacement slots 24 into one of the transposition slots 23. Subsequently, one of the displacement slots 24 loses its abutting effect on the connecting cone seat 25, and the elastic force of the return spring 29 gives an upward thrust to one side of the slider 27, causing the slider 27 to move upward inside the sliding groove 201. Moreover, the movement of the slider 27 drives the connecting cone seat 25 and the extension rod 28 to move upward synchronously. Thus, the connecting cone seat 25 moves upward synchronously along one side of the fixed seat 26 and inside one of the transposition slots 23, so that the radar 1 moves upward to the maximum position inside the portable cavity 12. As the rotation column 22 continues to rotate, the connecting cone seat 25 moves from inside one of the transposition slots 23 to inside the other displacement slot 24. Subsequently, the other displacement slot 24 abuts against the outside of the connecting cone seat 25 and pushes the connecting cone seat 25 to move downward inside the portable cavity 12. Then, the movement of the connecting cone seat 25 drives the slider 27 to move downward synchronously inside the sliding groove 201. Thus, the radar 1 moves into the portable cavity 12 under the movement of the connecting cone seat 25, for synchronously adjusting the monitoring range of the radar 1; Reference Figure 4 , Figure 5 and Figure 6 As shown in , Figure 2 , Figure 8 and Figure 9 , when the connecting cone seat 25 moves and guides inside the two transposition slots 23 and the two displacement slots 24, a neutral zone appears between the connecting cone seat 25 and one of the transposition slots 23 and the other displacement slot 24. Subsequently, the elasticity of the return spring 29 gives the connecting cone seat 25 a reset movement along one of the transposition slots 23, for maintaining a guiding movement between the connecting cone seat 25 and the other displacement slot 24. In this way, the movement reset of the radar 1 inside the portable cavity 12 is realized. When the radar 1 needs to be used again, as long as the connecting cone seat 25 is moved to the neutral position, the return spring 29 will automatically return the connecting cone seat 25 and the radar 1 accurately to the preset working position, ensuring the normal operation of the radar and the measurement accuracy; Reference Figure 2 , Figure 8 and Figure 9As shown, when the radar device 1 moves downward within the portable cavity 12, during the downward movement of the radar device 1, its exterior comes into contact with the surface of the friction roller 32. Immediately, rolling friction occurs between the exterior of the radar device 1 and the surface of the friction roller 32. At this time, the friction roller 32 rolls to drive the two connecting columns 36 and the two barbed gears 35 to rotate clockwise along one side of the connecting housing 33 and the stabilizing frame 34. Moreover, one of the ratchet teeth on the exterior of the barbed gear 35 moves along the bottom of the barbed claw 37 and pushes the barbed claw 37 to move upward. After one of the ratchet teeth on the exterior of the barbed gear 35 slides past the barbed claw 37, another ratchet tooth on the exterior of the barbed gear 35 comes into contact with the barbed claw 37 again, and so on. At the same time, rolling friction is formed between the remaining friction rollers 32 and the exterior of the portable cavity 12 that moves downward uniformly, preventing direct friction between the radar device 1 and the portable cavity 12 and providing a layer of protection for the surface of the radar device 1; Reference Figure 7 、 Figure 10 and Figure 11 As shown, when the radar device 1 moves upward within the portable cavity 12, by rotating the motor 43 to drive the guide rod 44 to rotate synchronously along one side of the base 11. Immediately, the rotation of the guide rod 44 drives the two position blocking frames 41 to rotate within the two centering grooves 45. At this time, the ends of the two position blocking frames 41 move out along the interior of the two centering grooves 45. Moreover, during the movement of the two position blocking frames 41, they drive the two position blocking plates 47 to move synchronously along the two guiding grooves 46. And the movement of the two position blocking plates 47 drives the two friction rollers 32 to move along one side of the portable cavity 12, enabling the two friction rollers 32 to contact different positions on the exterior of the upward-moving radar device 1, which can provide a more stable guiding effect for the radar device 1. Since the friction roller 32 maintains relative motion with the moving radar device 1, a relatively fixed contact relationship is formed between it and the radar surface, just like a track, which can strictly limit the movement path of the radar device 1, enabling the radar device 1 to only rise smoothly along a specific direction of the portable cavity 12, ensuring that the radar device 1 accurately returns to the working position and improving the accuracy of slope monitoring.
