Description

TECHNICAL FIELD

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

[0002] Geological exploration is to draw an engineering geological map through field investigation and measurement of the topography and geomorphology, stratum lithology, geological structure, etc. of a construction area. In the process of geological exploration, there are various landforms, especially in the process of slope exploration. The geological conditions of the slope are often complex and changeable (such as uneven rock-soil mass, fracture development, and active underground water, etc.). Traditional slope exploration methods (such as manual patrol, drilling sampling, and sensor monitoring) have low spatial resolution, small coverage range, and are difficult to monitor in real time. Therefore, a slope monitoring radar needs to be used. The radar can penetrate the ground surface, detect internal structures and hidden dangers, and provide more comprehensive information for exploration. Through radar wave reflection signals, hidden dangers such as unevenness, cavities, and weak interlayers of rock-soil mass can be identified. Currently, most commonly used radar detectors are divided into box type and movable type used with a cart. The traditional box type radar detector 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, the radar detector needs to be repeatedly carried manually, and its portability is poor.

[0038] The present application provides a portable slope monitoring radar for geological exploration as shown in Figure 1 and Figure 2 The present application provides a portable slope monitoring radar for geological exploration as shown in

[0039] The structure and principle of the radar instrument 1 are both prior art, so they are not described in detail in the present application; At present, in the process of geological slope exploration, the process of the radar instrument 1 usually includes the following steps:

[0040] 1. Define the monitoring target and scope (such as the entire slope or key area) and monitoring period (such as real-time monitoring or periodic monitoring);

[0041] 2. Radar equipment debugging, setting radar parameters (such as frequency, sampling interval, scanning mode, etc.), adjusting according to the monitoring target and slope material characteristics, calibrating the equipment to ensure the accuracy and consistency of the data;

[0042] 3. Data preprocessing, removing noise (such as electromagnetic interference, environmental interference, etc.), correcting equipment errors, filtering, enhancing and splicing radar images, generating clear monitoring results, through real-time data, the abnormal changes of the slope can be found in time, and potential landslides can be warned.

[0043] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the top end of the bottom support 11 is provided with a servo motor 202, and the servo motor 202 is used to drive the rotating column 22 to rotate, the radar instrument 1 is fixedly connected with a connecting cone seat 25 close to one end of the rotating column 22, the outer part of the rotating column 22 is respectively provided with two transposition grooves 23 and two displacement grooves 24 for guiding the movement of the connecting cone seat 25, and the two transposition grooves 23 are symmetrically arranged on the outer part of the rotating column 22, the two displacement grooves 24 are arranged in an arc structure, and the inside of the portable cavity 12 is fixedly connected with a fixed seat 26 for the up-down movement of the connecting cone seat 25; a sliding groove 201 is formed in one side of the fixed seat 26 close to the connecting cone seat 25, a sliding block 27 is fixedly connected to one side of the connecting cone seat 25, and the sliding block 27 is slidingly connected in the inside of the sliding groove 201, a extension rod 28 is fixedly connected to the bottom end of the sliding block 27, and the bottom end of the extension rod 28 penetrates through the sliding groove 201, a return spring 29 is connected between the sliding block 27 and the sliding groove 201, and the return spring 29 is sleeved on the outside of the extension rod 28;

[0044] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , in addition, the two displacement grooves 24 and the two transposition grooves 23 are communicated with each other, and are used to realize the up-down reciprocating movement of the connecting cone seat 25 in the displacement grooves 24 and the transposition grooves 23; and the rotation of the rotating column 22 drives the two displacement grooves 24 and the two transposition grooves 23 and the connecting cone seat 25 to work alternately and staggeredly, so that the connecting cone seat 25 drives the radar instrument 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, so as to reciprocate, which not only improves the monitoring range of the radar instrument 1 on the slope, makes the equipment flexible to use in different terrains and working conditions, improves the applicability of the equipment, but also can store the radar instrument 1 after detection, which is convenient for carrying the radar instrument 1;

[0045] ReferenceFigure 2 、 Figure 4 、 Figure 5 and Figure 6 When it is necessary to survey and monitor the geological slope, the first movable rod support 21 has two use states, which can be placed near the area to be surveyed and can be held and moved while surveying. The rotating column 22 is driven to rotate in the portable cavity 12 by the servo motor 202, and then the rotating column 22 drives 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 keep rotating contact with the adapter cone seat 25. At this time, the adapter cone seat 25 moves along one of the displacement grooves 24 into one of the transposition grooves 23, and then the displacement groove 24 loses the resistance effect on the adapter cone seat 25, and the reset spring 29 gives the slider 27 a side upward thrust by its own elastic force, so that the slider 27 moves upward along the inside of the sliding groove 201, and the slider 27 drives the adapter cone seat 25 and the extension rod 28 to move upward synchronously, so that the adapter cone seat 25 moves upward along the side of the fixed seat 26 and the inside of the transposition groove 23 synchronously, so that the radar instrument 1 moves upward to the maximum position in the inside of the portable cavity 12. With the continuous rotation of the rotating column 22, the adapter cone seat 25 moves from the inside of one transposition groove 23 to the inside of the other displacement groove 24, and then the other displacement groove 24 forms resistance with the outside of the adapter cone seat 25 and pushes the adapter cone seat 25 to move downward along the inside of the portable cavity 12. Then, the adapter cone seat 25 drives the slider 27 to move downward synchronously along the inside of the sliding groove 201, so that the radar instrument 1 moves to the inside of the portable cavity 12 under the movement of the adapter cone seat 25, for synchronous adjustment of the monitoring range of the radar instrument 1. At the same time, in the process of upward and downward movement of the adapter cone seat 25 driven by the rotating column 22, the rotating movement has good stability, and the transposition groove 23 and the displacement groove 24 can buffer and guide the movement of the adapter cone seat 25 to some extent, preventing the upward and downward movement of the radar instrument 1 from causing a large impact force due to direct vertical lifting, which can easily damage the detection radar instrument 1. The position and attitude of the radar instrument 1 are conveniently adjusted, the reliability and service life of the equipment are improved, and in summary, when some key areas are found temporarily, the survey personnel can hold the movable rod support 21 and drive the radar instrument 1 to move for precise survey of the temporarily found areas. When the slope is surveyed, it can be stably placed and surveyed in the survey area, and it can also be held to detect the temporarily found key areas, which can be immediately put into use, quickly monitor the changed areas, timely obtain the latest geological information, improve the rapid response of the radar instrument 1 to geological survey, and facilitate quick understanding of the stability of the slope.

[0046] Reference Figure 4 、 Figure 5 and Figure 6As shown, when the adapter cone 25 moves inside the two transposition grooves 23 and the two displacement grooves 24, a gap appears between the adapter cone 25 and one of the transposition grooves 23 and the other displacement groove 24, and the reset spring 29 automatically gives the adapter cone 25 a reset movement along one of the transposition grooves 23, so as to keep the adapter cone 25 moving along the other displacement groove 24, thereby achieving the movement reset of the radar instrument 1 in the portable cavity 12. When the radar instrument 1 needs to be used again, the adapter cone 25 is only needed to be moved to the gap position, and the reset spring 29 will automatically return the adapter cone 25 and the radar instrument 1 to the preset working position, ensuring the normal operation of the radar and the measurement accuracy. The combination design of the transposition grooves 23 and the displacement grooves 24 and the adapter cone 25 makes the space occupied in the vertical direction smaller, because the rotating action can "fold" or "compress" the storage path to a certain extent, thereby improving the portability of the equipment.

[0047] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the inside of the portable cavity 12 is provided with a plurality of limit support assemblies 3 for balancing and supporting the radar instrument 1 during movement; the limit support assembly 3 comprises a limit support frame 31 installed in the portable cavity 12, a friction roller 32 movably connected inside the limit support frame 31, and the friction roller 32 is used to move the radar instrument 1 along a predetermined path in the portable cavity 12. The friction roller 32 is provided with an adapter shell 33 at one end corresponding to the limit support frame 31, and the adapter shell 33 and the friction roller 32 are jointly connected with an adapter column 36; the inside of the adapter shell 33 is fixedly connected with a stabilizing frame 34, the stabilizing frame 34 and the adapter column 36 are jointly connected with a thorn gear 35, and the thorn gear 35 is used to drive the friction roller 32 to rotate in one direction along one end of the adapter shell 33 at all times. The side of the stabilizing frame 34 close to the thorn gear 35 is movably connected with a thorn pawl 37, and the end of the thorn pawl 37 is in contact with the outside of the thorn gear 35. The side of the stabilizing frame 34 close to the thorn pawl 37 is provided with a connecting column 38, and one end of the connecting column 38 and one side of the thorn pawl 37 are jointly connected with an extension spring 39.

[0048] Reference Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, and the number of several limit branch components 3 is four groups, and four groups of limit branch components 3 are located at four corners in portable cavity 12 respectively, and each group of limit branch components 3 includes two link shells 33, so the number of thorn gear 35, link column 36, thorn claw 37, stable frame 34, connecting column 38 and extension spring 39 is the same as link shell 33, and they are matched with each other, in addition, the outside of thorn gear 35 is formed by several teeth, and they are staggered, so that the moving direction between thorn gear 35 and thorn claw 37 is limited, when thorn gear 35 rotates clockwise, friction roller 32 contacts and rolls with the outer wall of radar instrument 1 moving downward, at this time, one of the teeth on the outside of thorn gear 35 moves along the bottom of thorn claw 37, and pushes thorn claw 37 to move upward, and after one of the teeth on the outside of thorn gear 35 slides through thorn claw 37, the other tooth on the outside of thorn gear 35 recontacts with thorn claw 37, and so on, keeping thorn gear 35 rotating clockwise, when thorn gear 35 rotates counterclockwise, friction roller 32 contacts with the outside of radar instrument 1 moving upward, at this time, the end of thorn claw 37 contacts with the two adjacent teeth on the outside of thorn gear 35, preventing thorn gear 35 from rotating counterclockwise;

[0049] Referring to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, when radar instrument 1 moves downward in portable cavity 12, the outside of radar instrument 1 contacts with the surface of friction roller 32, and then the outside of radar instrument 1 rolls and rubs with the surface of friction roller 32, at this time, two link columns 36 and two thorn gears 35 rotate clockwise along one side of link shell 33 and stable frame 34, and one of the teeth on the outside of thorn gear 35 moves along the bottom of thorn claw 37, and pushes thorn claw 37 to move upward, and after one of the teeth on the outside of thorn gear 35 slides through thorn claw 37, the other tooth on the outside of thorn gear 35 recontacts with thorn claw 37, and so on, while the rest of friction rollers 32 roll and rub with the outside of portable cavity 12 moving downward uniformly, preventing direct friction between radar instrument 1 and portable cavity 12, and providing a layer of protection for the surface of radar instrument 1; and four groups of limit branch components 3 are located at four corners in portable cavity 12 respectively, which can guide radar instrument 1 when it moves downward, ensuring that radar instrument 1 always slides along the predetermined path during the movement, ensuring that radar instrument 1 can be accurately stored in the designated position, and improving the operation stability of the equipment;

[0050] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, when the adapter cone seat 25 is in the neutral position in the transposition groove 23, and the radar instrument 1 is moved upward in the portable cavity 12, the radar instrument 1 moves upward and comes into contact with the outside of the friction roller 32, and then the friction roller 32 comes into contact with the outside of the upwardly moving radar instrument 1. At this time, the end of the thorn claw 37 is in contact with the two adjacent teeth of the thorn gear 35, preventing the thorn gear 35 from rotating counterclockwise, so that the friction roller 32 cannot rotate along the limiting support 31. At this time, the contact between the friction roller 32 and the surface of the radar instrument 1 becomes static friction, which can provide greater support force. This friction can control the moving speed of the radar instrument 1 when it moves upward, prevent the radar instrument 1 from colliding due to moving too fast, and avoid affecting the work efficiency due to moving too slowly, so as to ensure that the radar instrument 1 returns to the working position accurately. The stable working position can ensure that the beam of the radar instrument 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, the friction roller 32 cannot rotate, and although the static friction force increases, the speed of the radar instrument 1 moving upward is usually slow, and the material of the friction roller 32 is usually wear-resistant, so it will not cause excessive wear to the surface of the radar instrument 1 or the friction roller 32. In this way, the service life of the friction roller 32 and the radar instrument 1 is prolonged while the function is ensured.

[0051] Referring to Figure 2 , Figure 10 and Figure 11 , the outer part of the base support 11 is provided with a position limiting assembly 4 for moving the limiting support assembly 3 along a specific track outside the radar instrument 1. The position limiting assembly 4 includes two centering grooves 45 symmetrically formed at the top end of the base support 11, two position limiting frames 41 movably connected inside the two centering grooves 45, two guide grooves 46 symmetrically formed inside the portable cavity 12 and communicating with the inside of the two centering grooves 45, and a position limiting plate 47 connected between the limiting support 31 and the position limiting frame 41 and slidingly connected inside the guide groove 46.

[0052] Moreover, the position limiting assembly 4 is connected with the two limiting support assemblies 3, and the number of the guide grooves 46, the position limiting plate 47, the position limiting frame 41 and the centering groove 45 is two.

[0053] Referring to Figure 2 , Figure 10 and Figure 11 , one side of the base support 11 is fixedly connected with a centering frame 42, and the other side of the base support 11 is rotatably connected with a guide rod 44 matched with the two position limiting frames 41. The side of the centering frame 42 close to the guide rod 44 is fixedly connected with a rotating motor 43, and the rotating motor 43 is used to drive the guide rod 44 to rotate. The two position limiting frames 41 are moved out of the two centering grooves 45 by the rotation of the guide rod 44, and the sliding-out positions of the two position limiting frames 41 are located on both sides of the radar instrument 1. The two position limiting frames 41 are designed in L-shaped structure.

[0054] refer to Figure 2 、 Figure 10 and Figure 11 As shown, when the radar instrument 1 moves upward in the portable cavity 12, the guide rod 44 is driven by the rotating motor 43 to rotate synchronously along one side of the base 11, and then the guide rod 44 rotates to drive the two stop frames 41 to rotate along the two centering grooves 45. At this time, the ends of the two stop frames 41 move out along the inside of the two centering grooves 45, and the two stop frames 41 drive the two stop plates 47 to move synchronously along the two guide grooves 46 during the movement. Moreover, the movement of the two stop 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 external positions of the upwardly moving radar instrument 1, which can provide a more stable guiding effect for the radar instrument 1. Since the friction roller 32 maintains relative motion with the moving radar instrument 1, a relatively fixed contact relationship is formed between it and the radar surface. The system, like a track, can strictly limit the moving path of the radar instrument 1, so that the radar instrument 1 can only rise steadily along the specific direction of the portable cavity 12, avoiding deviation or shaking during the ascent, 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 two centering grooves 45, the position blocking frames 41 and the radar instrument 1 slide out along the inside of the portable cavity 12 to form a match, so that the parts of the two position blocking frames 41 that slide out of the two centering grooves 45 are located on both sides of the radar instrument 1, so that the two position blocking frames 41 are used to block the two sides of the portable cavity 12, and then can resist the wind on both sides of the radar instrument 1, improve the anti-interference ability of the radar instrument 1, ensure the continuity and stability of the monitoring work, and detect abnormal changes in the slope in a timely and accurate manner.

[0055] Working principle:

[0056] When in use;

[0057] refer to Figure 1 and Figure 2 As shown, when it is necessary to survey and monitor the geological slope, the movable rod holder 21 has two use states, which can be placed near the place where the survey is required, or can be held and moved while surveying;

[0058] refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, by servo motor 202 driving rotating column 22 to rotate in portable cavity 12, rotating column 22 drives two displacement grooves 24 and two displacement grooves 23 to rotate synchronously, so that two displacement grooves 24 and two displacement grooves 23 keep rotating contact with adapter cone seat 25. At this time, adapter cone seat 25 moves along one of displacement grooves 24 into one of displacement grooves 23, and one of displacement grooves 24 loses the effect of resisting adapter cone seat 25, and reset spring 29 gives slider 27 a lateral upward thrust, so that slider 27 moves upward along the inside of sliding groove 201, and slider 27 drives adapter cone seat 25 and extension rod 28 to move upward synchronously, so that adapter cone seat 25 moves upward along one side of fixed seat 26 and inside one of displacement grooves 23 synchronously, so that radar instrument 1 moves upward to the maximum position in portable cavity 12. With the continuous rotation of rotating column 22, adapter cone seat 25 moves from inside one of displacement grooves 23 to inside another displacement groove 24, and another displacement groove 24 forms resistance with the outside of adapter cone seat 25 and pushes adapter cone seat 25 to move downward in portable cavity 12. Then, adapter cone seat 25 drives slider 27 to move downward synchronously along the inside of sliding groove 201, so that radar instrument 1 moves in portable cavity 12 under the movement of adapter cone seat 25, for synchronous adjustment of the monitoring range of radar instrument 1.

[0059] Referring to Figure 4 , Figure 5 and Figure 6 When adapter cone seat 25 moves in two displacement grooves 23 and two displacement grooves 24, an empty area appears between adapter cone seat 25 and one of displacement grooves 23 and another displacement groove 24, and reset spring 29 gives adapter cone seat 25 a reset force to move in one of displacement grooves 23, for guiding the movement between adapter cone seat 25 and another displacement groove 24. In this way, radar instrument 1 is reset in portable cavity 12, and when radar instrument 1 needs to be used again, adapter cone seat 25 is moved to the empty position, and reset spring 29 automatically returns adapter cone seat 25 and radar instrument 1 to the preset working position, ensuring the normal work of the radar and the measurement accuracy.

[0060] Referring to Figure 2 , Figure 8 and Figure 9As shown, when the radar instrument 1 moves downward in the portable cavity 12, the external surface of the radar instrument 1 is in contact with the surface of the friction roller 32 by moving downward, and then the external surface of the radar instrument 1 rolls and rubs with the surface of the friction roller 32, at this time, the friction roller 32 rolls to drive the two engaging columns 36 and the two ratchet gears 35 to rotate clockwise along one side of the engaging shell 33 and the stable frame 34, and one of the ratchet teeth on the external surface of the ratchet gear 35 moves along the bottom of the ratchet claw 37 and pushes the ratchet claw 37 to move upward, and after the one of the ratchet teeth on the external surface of the ratchet gear 35 slides with the ratchet claw 37, the other of the ratchet teeth on the external surface of the ratchet gear 35 recontacts with the ratchet claw 37, and the above process is repeated, at the same time, the external surface of the remaining friction rollers 32 uniformly rubs with the external surface of the portable cavity 12 to prevent the direct friction between the radar instrument 1 and the portable cavity 12, and a layer of protection is provided for the surface of the radar instrument 1.

[0061] Referring to Figure 7 , Figure 10 and Figure 11 As shown, when the radar instrument 1 moves upward in the portable cavity 12, the guide rod 44 is driven to rotate along one side of the bottom support 11 by rotating the motor 43, and then the guide rod 44 rotates to drive the two position blocking frames 41 to rotate in the two centering grooves 45, at this time, the end portions of the two position blocking frames 41 move out of the internal surfaces of the two centering grooves 45, and the two position blocking frames 41 drive the two position blocking plates 47 to move synchronously in the two guide grooves 46 during the movement, 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, so that the two friction rollers 32 contact different positions on the external surface of the upward moving radar instrument 1, and can provide more stable guiding effect for the radar instrument 1, because the friction roller 32 keeps relative motion with the moving radar instrument 1, and a relatively fixed contact relationship is formed between the friction roller 32 and the radar surface, like a track, which can strictly limit the moving path of the radar instrument 1, so that the radar instrument 1 can only smoothly ascend along the specific direction of the portable cavity 12, and the accuracy of the slope monitoring is improved.

[0062] The above only describes some exemplary embodiments of the present application in a descriptive manner, and it is needless to say that those skilled in the art can modify the described embodiments in various manners without departing from the spirit and scope of the present application, therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
