Description

Technical Field

[0001] The invention relates to the technical field of geological environment monitoring, and in particular to a karst geological environment monitoring device. Background Art

[0002] Karst is a general term for the geological action of water on soluble rocks (carbonate rocks, gypsum, rock salt, etc.) mainly through chemical dissolution, supplemented by mechanical actions such as erosion, subsidence and collapse of flowing water, as well as the phenomena produced by these actions. The karst areas in my country are mainly concentrated in the southwest region. Due to the complex topography and fragile ecological environment in the karst areas, with the development of land resources, water resources and mineral resources in the karst areas by humans, collapse often occurs in the karst areas. This is a very serious geological disaster for cities located in the karst areas, which seriously affects the construction of the city and people's life safety. Therefore, it is very important to effectively monitor the karst geological environment and prevent it before it happens.

[0003] In the prior art, the devices for karst geological environment detection mainly use geological radar for monitoring. However, the ground surface of the karst area is mostly undulating and uneven, which makes it difficult to install the geological radar horizontally on the ground. Moreover, over time, the ground in the karst area will sink to varying degrees, causing the geological radar that was originally installed horizontally to tilt, thereby seriously affecting the accuracy of the detection results. For example, the Chinese invention patent with application number CN201811005201.5, authorization announcement number CN109188539B, and name "A device for karst geological environment monitoring" announced "A device for karst geological environment monitoring, including a geological radar, the bottom end of the geological radar is screwed to a support component, and the left and right sides of the support component are both clamped with one side of a tightening mechanism, and the other side of the tightening mechanism is welded with a cross plate, and the top of the cross plate is plugged with a conical column; the support component includes a bottom plate, and the lower surface of the bottom plate is reserved with a number of recessed grooves. A groove, a spring is clamped at the top of the inner cavity of the groove, a slide plate is clamped at the bottom end of the spring, the left and right sides of the slide plate are embedded in the slide groove inner cavity opened on the left and right sides of the inner cavity of the groove, a rectangular rod is welded at the bottom end of the slide plate, and the bottom end of the rectangular rod extends out of the bottom plate. This invention, through the cooperation of several springs and rectangular rods, when the device is installed, the rectangular rod contacts the ground to squeeze the spring to contract, so that the geological radar can be installed horizontally even if it is installed on an uneven ground, or the geological radar can be kept in a horizontal state even if the ground settles and produces an uneven phenomenon.

[0004] The above invention patent, through the cooperation of springs and rectangular rods, can solve the problem that the geological radar can be installed horizontally on uneven ground to a certain extent, but it cannot completely and effectively solve the problem that the geological radar originally installed horizontally can still maintain a horizontal state after the ground sinks, because the adjustable structure adopted by the above invention patent is a spring. When the ground at a certain place on the front and back sides of the geological radar sinks, the spring corresponding to the sinking position will stretch to make the corresponding rectangular rod abut against the ground. However, after the spring is stretched, its own elastic force will decrease, so that the elastic force of the spring is insufficient to support the geological radar to make the geological radar horizontal, thereby the original The horizontally installed geological radar will press down the extended spring, causing the geological radar to tilt forward and backward, resulting in inaccurate monitoring of the geological radar. The geological radar is installed on the supporting component, and the tightening mechanism on the left and right sides of the supporting component uses the winding of the chain to fix the supporting component. The chain is easy to deform and is located on the left and right sides of the supporting component, so that the tightening mechanism cannot change the condition of the geological radar tilting forward and backward. Therefore, the above-mentioned invention patent cannot completely and effectively solve the problem that the originally horizontally installed geological radar can still maintain a horizontal state after ground subsidence, which may easily cause inaccurate monitoring results of the geological radar after ground subsidence. Summary of the invention

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8As shown, a karst geological environment monitoring device provided by an embodiment of the present invention includes a support seat 2, a receiving chamber 201 is arranged in the support seat 2, the receiving chamber 201 is filled with a supporting liquid, a deformation pad 4 is sealed at the opening of the receiving chamber 201, the deformation pad 4 floats on the supporting liquid, and a geological radar 1 is fixedly installed on the deformation pad.

[0030] Specifically, the karst geological environment monitoring device provided in this embodiment is used to monitor the soil quality in karst areas to avoid economic losses and personal injuries caused by ground subsidence. In this embodiment, the mass of the geological radar 1 is evenly distributed, and its center of gravity is located at the center. The support seat 2 is used to contact the ground, the accommodating cavity 201 is used to hold the supporting liquid, the deformation pad 4 is fixedly installed at the opening of the accommodating cavity 201 by gluing, and the opening of the accommodating cavity 201 is sealed so that the supporting liquid will not flow out of the accommodating cavity 201. The supporting liquid can be water or oil, which is used to support the deformation pad 4 and the geological radar 1, so that the geological radar 1 and the deformation pad 4 float on the liquid surface of the supporting liquid. Because the mass of the geological radar 1 is evenly distributed, when the supporting liquid is stable, the geological radar 1 will not tilt on the deformation pad 4. The working principle of the karst geological environment monitoring device in this embodiment is to place the support seat 2 with the geological radar 1 installed on the ground to be monitored. After a while, the supporting liquid gradually stabilizes, so that the liquid surface is horizontal. Because the geological radar 1 and the deformation pad 4 float on the liquid surface of the supporting liquid, the geological radar 1 is in a horizontal state at this time. When the ground settles and causes the ground to be uneven, the support seat 2 will tilt, causing the supporting liquid to shake slightly, but after waiting for a short time, the supporting liquid will automatically return to stability. At this time, the liquid surface of the supporting liquid automatically returns to a horizontal state, so that the geological radar 1 will also return to a horizontal state again. In the prior art, when the ground at a certain place on the front and back sides of the geological radar 1 settles, the spring corresponding to the settlement position will stretch so that the corresponding rectangular rod abuts against the ground, but after the spring is stretched, its own elastic force will decrease, so that the elastic force of the spring is not enough to support the geological radar to make the geological radar horizontal, so that the geological radar originally installed horizontally will press down the elongated spring, causing the geological radar to tilt forward and backward, thereby causing inaccurate monitoring of the geological radar. The main innovation of the present invention is that a accommodating chamber 201 is opened inside the supporting seat 2, and the accommodating chamber 201 is filled with supporting liquid. The supporting liquid floats the geological radar 1 and the deformation pad 4 on the liquid surface. The liquid surface of the supporting liquid will always remain horizontal after the supporting liquid is stable. This can ensure that the geological radar 1 can automatically return to a horizontal state after the ground settles.

[0031] In this embodiment, a deformation pad 4 is sealed in the accommodating cavity 201 of the support seat 2, and a supporting liquid is filled in the accommodating cavity 201 of the support seat 2. The supporting liquid can support the deformation pad 4, thereby supporting the geological radar 1, so that the geological radar 1 and the deformation pad 4 float on the liquid surface of the supporting liquid. The mass of the geological radar 1 is evenly distributed, and because the liquid surface of the supporting liquid is always horizontal in a stable state, the geological radar 1 is also horizontal. Compared with the prior art, when the ground settles, the geological radar 1 can return to a horizontal state after the supporting liquid becomes stable after a short shake, thereby ensuring that the geological radar 1, which was originally in a horizontal state, can remain horizontal after the ground settles.

[0032] In this embodiment, by providing a supporting liquid, the geological radar 1 will not come into contact with hard objects, which can play a good buffering role for the geological radar 1 and thus the geological radar 1 is not easily damaged.

[0033] In this embodiment, the deformation pad 4 is an elastic rubber pad. The elastic rubber pad has a small gravity, so it can float on the liquid surface of the supporting liquid. At the same time, by utilizing its elastic characteristics, when the geological radar 1 is installed on the deformation pad 4, the gravity of the geological radar 1 causes the deformation pad 4 to deform, so that the bottom of the deformation pad 4 fits with the liquid surface of the supporting liquid, ensuring that the surface of the deformation pad 4 covered by the geological radar 1 is a horizontal plane, thereby keeping the geological radar 1 level.

[0034] In this embodiment, a filling port is provided on the support seat 2, and a sealing plug 3 is detachably sealed in the filling port. The filling port is used to add supporting liquid to the accommodating cavity 201. After the supporting liquid is added, the sealing plug 3 can seal the filling port to prevent leakage of the supporting liquid.

[0035] Furthermore, the liquid filling port is cylindrical, and the sealing plug 3 includes a threaded tube 303, which is threadedly connected to the liquid filling port, and the threaded tube 303 is connected to a piston 305 through a spring 304. The piston 305 is located in the liquid filling port and slides with the inner wall of the liquid filling port. The end of the threaded tube 303 located outside the liquid filling port is threadedly connected to a cover body 301 for limiting the spring 304. The threaded connection between the threaded tube 303 and the liquid filling port can realize a detachable connection between the sealing plug 3 and the liquid filling port; the piston 305 can further improve the sealing effect of the liquid filling port; the spring 304 plays a further buffering role, and the spring 304 is also used to consume the kinetic energy of the supporting liquid when it shakes, thereby reducing the frequency of the supporting liquid shaking and allowing the supporting liquid to return to a stable state faster.

[0036] Because when the support seat 2 shakes or tilts, the supporting liquid generates kinetic energy, causing the supporting liquid to shake to varying degrees in the accommodating chamber 201. The shaking of the supporting liquid is obviously not conducive to the geological radar 1 to quickly restore to a horizontal state. By setting the spring 304, when the supporting liquid shakes, the supporting liquid continuously applies pressure to the piston 305. When the piston 305 is pressurized, the piston 305 will squeeze the spring 304 and compress and deform it, thereby converting the kinetic energy of the supporting liquid into the internal energy of the spring 304. In this conversion process, the kinetic energy of the supporting liquid will be consumed once. When the pressure value of the piston 305 is less than the internal energy of the spring 304, the spring 304 will stretch to release its own elastic force, thereby converting the internal energy of the spring 304 into the kinetic energy of the supporting liquid again. In this conversion process, the supporting liquid will use its kinetic energy to hinder the extension of the spring 304, and the kinetic energy of the supporting liquid will be consumed again in the process of obstruction. The conversion of the kinetic energy of the supporting liquid into the internal energy of the spring 304 and the conversion of the internal energy of the spring 304 into the kinetic energy of the supporting liquid constitute a complete energy conversion cycle. During this conversion cycle, the use of the spring 304 will consume a large amount of the kinetic energy of the supporting liquid. Increasing the consumption of the kinetic energy of the supporting liquid will reduce the frequency of the shaking of the supporting liquid and make the supporting liquid return to a calm state more quickly, thereby allowing the geological radar 1 to quickly return to a horizontal state.

[0037] Furthermore, an annular flange is provided on the inner wall of the threaded tube 303, one end of the spring 304 is fixedly connected to the movable plate 302, and the other end is fixedly connected to the piston 305, the movable plate 302 is slidably provided between the annular flange and the cover body 301, and the diameter of the movable plate 302 is larger than the inner diameter of the annular flange.

[0038] By utilizing the above structure, the spring 304 and the threaded tube 303 are movably arranged. When the threaded tube 303 is screwed onto the liquid filling port, the spring 304 will not rotate together with the threaded tube 303 and the piston 305, thereby improving the convenience of installing the threaded tube 303 and eliminating the risk of the spring 304 and the piston 305 being separated when the threaded tube 303 is installed. Moreover, the movable plate 302 is arranged between the annular flange and the cover body 301, and the spring 304 and the piston 305 can be limited. When the sealing plug 3 is disassembled, the threaded tube 303 can be pulled outward to be removed from the liquid filling port together with the spring 304 and the piston 305, and the spring 304 and the piston 305 will not fall into the accommodating chamber 201.

[0039] In order to make the geological radar 1 adapt to a greater degree of ground subsidence, the support base 2 can be kept horizontally placed in the initial state. Since the karst geology is mostly uneven ground, in order to make the support base 2 also keep horizontal on the uneven ground, in this embodiment, a plurality of support legs 5 are symmetrically arranged on the support base 2, and the support legs 5 are tubular bodies. The inner cavity of each support leg 5 is connected with the chamber, and a support rod 7 for contacting the ground is provided in the inner cavity of the support leg 5 for sliding sealing. The number of support legs 5 is preferably four, and the four support legs 5 are respectively located at the four corners of the support base 2. The inner cavities of the plurality of support legs 5 are connected, and the support rod 7 is in contact with the ground to bear the gravity of the geological radar 1 and the support base 2. When the forces on the support rods 7 are consistent, the support rods 7 will reach a balanced state. When the forces on one of the support rods 7 change, the forces on the other support rods 7 will automatically adjust until the forces on the support rods 7 are consistent again.

[0040] Through the above-mentioned mechanism, in this embodiment, the geological radar 1 is located at the center of the support base 2, and the mass of the support base 2 is also evenly distributed, so that when the geological radar 1 and the support base 2 are horizontal, the gravity of the geological radar 1 and the support base 2 will be evenly distributed on each support rod 7, that is, when the force on each support rod 7 is consistent, the geological radar 1 and the support base 2 are in a horizontal state.

[0041] When the monitoring device is placed on an uneven ground, each support rod 7 contacts the ground in turn. The support rod 7 that contacts the ground first will move upward along the inner cavity of the support leg 5, and use the supporting fluid to transfer kinetic energy to each support rod 7, so that the other support rods 7 move downward until all the support rods 7 contact the ground. When all the support rods 7 stop moving up and down, the force on each support rod 7 is consistent, so that the geological radar 1 and the support base 2 are automatically adjusted to a horizontal state.

[0042] Furthermore, a plurality of counterweights 12 are symmetrically arranged on the support base 2, and the counterweights 12 include a connecting rope fixedly connected to the support base 2, and a plurality of gravity blocks arranged at intervals are fixedly installed on the connecting rope. Each gravity block is heavy, which can increase the stability of the support base 2 and the geological radar 1. At the same time, the counterweights 12 can be used to adjust the force applied to each support rod 7 when the support base 2 is tilted, so that the support base 2 can automatically adjust from the tilted state to the horizontal state or a state close to the horizontal state.

[0043] The number of counterweights 12 is the same as the number of support legs 5, and each counterweight 12 is located on the center line between the multiple support legs 5. When the ground settles, the support rod 7 corresponding to the position with deeper settlement will be separated from the ground, causing the support seat 2 to tilt in the direction of the support rod 7. When the support seat 2 tilts, the multiple gravity blocks on the counterweight 12 corresponding to the inclined side will contact the ground in sequence, thereby greatly reducing the weight of the inclined side. Under the gravity of the counterweight 12, the force value of the support rod 7 corresponding to the inclined side will be smaller than the force value of other support rods 7. In order to restore each support rod 7 to a balanced state, the other support rods 7 with greater force will move upward and shorten, causing the support rod 7 corresponding to the inclined side to move downward and lengthen, thereby automatically adjusting the inclined support seat 2 so that the support seat 2 moves toward the inclined side. In the opposite direction, the gravity block on the counterweight 12 corresponding to the inclined side will gradually leave the ground, thereby reducing the inclination of the support seat 2, so that it automatically adjusts back to a horizontal state or a near-horizontal state. At the same time, in conjunction with the elastic force of the deformation pad 4, the geological radar 1 can be pulled to limit its position, so that the geological radar 1 will not move significantly to the inclined side when the support seat 2 is tilted, causing the weight of the inclined side to increase sharply. Moreover, because the deformation pad 4 is elastic, when it pulls the geological radar 1, it is a back-and-forth shaking pull, which will repeatedly change the force distribution of each support rod 7, providing additional power for the support seat 2 to adjust the inclination, so as to facilitate the support seat 2 to return to a horizontal position. When each counterweight 12 returns to its initial state, that is, when it leaves the ground, under the elastic force of the deformation pad 4, the geological radar 1 can be gradually restored to its original position, that is, located at the center of the support seat 2. At this time, the forces of each support seat 2 are consistent again, and the support seat 2 will return to a horizontal state.

[0044] The outer surface of the support rod 7 is provided with a groove, and a sealing ring is embedded in the groove. The outer surface of the sealing ring is pressed against the inner wall of the support leg 5. The bottom of the support leg 5 is screwed with a limiting tube 6, and the inner wall of the limiting tube 6 is slidingly fitted with the outer surface of the support rod 7. By using the inner wall of the limiting tube 6 slidingly fitting with the outer surface of the support rod 7, the position of the support rod 7 can be constrained to prevent the support rod 7 from tilting in the horizontal direction; at the same time, since the sealing ring has a sealing effect, its outer diameter needs to be larger than the diameter of the support rod 7, so that the diameter of the inner cavity where the limiting tube 6 fits with the outer surface of the support rod 7 is smaller than the outer diameter of the sealing ring, so that the limiting tube 6 can also limit the sealing ring to prevent the sealing ring from sliding out of the inner cavity of the support leg 5, causing the support rod 7 to separate from the support leg 5.

[0045] In this embodiment, in order to prevent the monitoring device from shifting, a telescopic rod 8 is provided on the support seat 2, and the telescopic rod 8 is located at the bottom center of the support seat 2. A first bearing seat 13 and a second bearing seat 14 are provided on the top of the telescopic rod 8. The first bearing seat 13 is fixedly connected to the telescopic rod 8, and the first bearing seat 13 and the second bearing seat 14 are arranged opposite to each other. A plurality of connecting pieces 17 are installed on the first bearing seat 13 by screws. When the screw is loosened, the connecting piece 17 can rotate around the screw. The second bearing seat 14 is provided with a plurality of connecting pieces 17 that are connected to each connecting piece 17 one by one. The corresponding screw holes 15 can be connected with the first bearing seat 13 and the second bearing seat 14 by installing screws on the screw holes 15, and a movable space is enclosed between the first bearing seat 13 and the second bearing seat 14, in which a connecting ball 16 is rotatably connected, and the top of the connecting ball 16 is fixedly connected to the bottom of the support seat 2, and a fixing plate 9 is fixedly installed at the bottom of the telescopic rod 8, and a plurality of mounting holes are arranged circumferentially, and the number of mounting holes is not less than three, and a fixing nail 10 is inserted in each mounting hole. The fixing nail 10 is used to nail into the ground, so as to fix the telescopic rod 8, and the fixing of the telescopic rod 8 can limit the position of the monitoring device and prevent displacement. By using the rotatable connection between the connecting ball 16 and the first bearing seat 13 and the second bearing seat 14, the support seat 2 can still be rotated, so as not to affect the above-mentioned operation of adjusting the support seat 2 to a horizontal state.

[0046] Furthermore, each fixing nail 10 is sleeved with a compression spring 11, which is located between the top cap of the fixing nail 10 and the fixing plate 9. The fixing plate 9 is compressed by the elastic force of the compression spring 11, thereby improving the firmness of the fixing plate 9.

[0047] Furthermore, there are at least two screw holes 15 on the second bearing seat 14 that correspond to each connecting piece 17, and the distances from each screw hole 15 to the corresponding screw on the first bearing seat 13 are different. By connecting the connecting piece 17 to different screw holes 15 on the second bearing seat 14, the distance between the opposite surfaces of the first bearing seat 13 and the second bearing seat 14 can be adjusted, so that the size of the activity space between the first bearing seat 13 and the second bearing seat 14 can be changed, and then the tightness of the connection between the connecting ball 16 and the activity space can be changed.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

The deformation pad (4) is an elastic rubber pad; A plurality of support legs (5) are symmetrically arranged on the support seat (2), the support legs (5) being tubular bodies, the inner cavities of the respective support legs (5) being in communication with the accommodating cavity (201), and support rods (7) for contacting the ground being slidably sealed in the inner cavities of the support legs (5); A plurality of counterweights (12) are symmetrically arranged on the support seat (2), the counterweights (12) comprising a connecting rope fixedly connected to the support seat (2), and a plurality of gravity blocks arranged at intervals are fixedly mounted on the connecting rope; When the support seat (2) tilts, a plurality of gravity blocks on the counterweight (12) corresponding to the tilted side will contact the ground in sequence, and under the gravity of the counterweight (12), the force value of the support rod (7) corresponding to the tilted side will be smaller than the force values ​​of other support rods (7); In order to restore each support rod (7) to a balanced state, the other support rods (7) subjected to greater force will move upward and become shorter, so that the support rods (7) corresponding to the inclined side will move downward and become longer, and the inclined support seat (2) will be automatically adjusted so that the support seat (2) moves in the direction opposite to the inclined side. The gravity block on the counterweight (12) corresponding to the inclined side will gradually leave the ground, thereby reducing the degree of inclination of the support seat (2) so that it automatically adjusts back to a horizontal state or a state close to the horizontal state. In combination with the elastic force of the deformation pad (4), the geological radar (1) is pulled to limit its position. The geological radar (1) will not move significantly to the inclined side when the support seat (2) is inclined, causing the weight on the inclined side to increase sharply. When all the counterweights (12) are restored to their initial state, the geological radar (1) is gradually restored to its original position, i.e., the center position of the support seat (2), under the elastic force of the deformation pad (4). At this time, the forces on all the support seats (2) are consistent again, and the support seats (2) are restored to a horizontal state.

2. The karst geological environment monitoring device according to claim 1, characterized in that: The number of the counterweights (12) is the same as the number of the supporting legs (5), and each of the counterweights (12) is located on a center line between two of the supporting legs (5).

3. The karst geological environment monitoring device according to claim 1 is characterized in that: The geological radar (1) is located at the center of the support base (2).

4. The karst geological environment monitoring device according to claim 1 is characterized in that: The outer surface of the support rod (7) is provided with a groove, a sealing ring is embedded in the groove, the outer surface of the sealing ring is pressed against the inner wall of the support leg (5), the bottom of the support leg (5) is threadedly connected to a limiting tube (6), and the inner wall of the limiting tube (6) is slidably fitted with the outer surface of the support rod (7).
