Description

Technical Field

[0001] The utility model relates to the technical field of geological environment monitoring, and relates to a device for mine geological environment monitoring. Background Art

[0002] Mine geological environment monitoring is a process of continuous observation and evaluation of mines and their surrounding environments. The main purpose of mine geological environment monitoring is to ensure the safety of mine operations, prevent the occurrence of geological disasters such as landslides and collapses, and protect the ecological environment. Through real-time monitoring, potential risks can be detected in a timely manner and corresponding measures can be taken, thereby reducing or avoiding possible disaster losses.

[0003] When conducting mine geological environment monitoring, ground penetrating radar is commonly used to observe the ground. Currently, when detecting mine slopes, the ground penetrating radar is generally fixed to the ground by means of plug pins, and then a protective cover is placed outside the ground penetrating radar for simple protection. However, when conducting detection in an environment with heavy rainfall, the soil on the mountain is very likely to loosen, resulting in unstable installation of the ground penetrating radar. Moreover, when rainwater washes the slope surface, there will be falling rocks, which easily damage the protective cover and may affect the normal use of the ground penetrating radar. Therefore, there is an urgent need for a device for mine geological environment monitoring to solve the above problems. Content of the Utility Model

[0004] In view of the above technical problems existing in the prior art, a device for mine geological environment monitoring is provided, which solves the problems that when conducting detection in an environment with heavy rainfall, the soil on the mountain is very likely to loosen, resulting in unstable installation of the ground penetrating radar, and when rainwater washes the slope surface, there will be falling rocks, which easily damage the protective cover and may affect the normal use of the ground penetrating radar.

[0005] The purpose and efficacy of the utility model are achieved by the following specific technical means:

[0006] A device for mine geological environment monitoring includes a surrounding frame;

[0007] A plurality of uniformly distributed mounting holes are opened on the outer periphery of the bottom of the surrounding frame. First electric cylinders are fixed at the tops of the mounting holes. Positioning pins are fixed at the output ends of the first electric cylinders. A plurality of longitudinally distributed side grooves are opened on the outer sides of the positioning pins, and elastic limiting components are installed in the side grooves;

[0008] Insertion holes with the same number and communicating with the mounting holes are opened at the top of the surrounding frame. A limiting frame is arranged above the surrounding frame. A plurality of limiting feet are arranged on the limiting frame. The limiting feet respectively pass through the plurality of insertion holes and are attached to the outer walls of the adjacent positioning pins. The limiting feet are used for limiting the elastic limiting components.

[0009] Optionally, the elastic limiting assembly includes a spring and a limiting pin, the spring is transversely fixed in the side groove, the limiting pin is fixed to the outer end of the spring, and the tip of the limiting pin is in contact with the limiting foot.

[0010] Optionally, an arc portion is provided on the upper side of the tip of the limiting pin, and a plurality of protrusions are welded to the tip of the limiting pin.

[0011] Optionally, a cross bar is fixed in the frame, and a protective cover with an open bottom is elastically connected to the bottom of the cross bar, and a geological radar is installed in the protective cover.

[0012] Optionally, a mounting seat is fixed in the middle of the top of the crossbar, a second electric cylinder is fixed in the mounting seat, and an output end of the second electric cylinder passes through the mounting seat and is detachably connected to the limit frame.

[0013] Optionally, a protective cover is detachably connected to the top of the enclosure frame, and the inner top of the protective cover is detachably connected to the output end of the second electric cylinder.

[0014] Optionally, the limiting frame is a steel frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This device is used for monitoring the geological environment of mines. The frame plays a certain role in diverting and blocking sand, gravel and soil, preventing them from falling directly onto the protective cover and the geological radar. It plays a good protective role for the protective cover and the geological radar, so the geological radar can continue to operate normally even on rainy days.

[0017] The limit frame limits the elastic limit assembly to prevent it from popping out of the side groove when the positioning nail is not completely driven into the soil. When the device is removed from the ground, the limit foot can be moved downward to press the elastic limit assembly into the side groove, making it easier to remove the device.

[0018] After the elastic limit assembly pops out from the side groove and penetrates into the soil, it can enhance the stability of the positioning pin in the soil, and effectively prevent the loosening of the soil on the mountain during rainfall, which may lead to unstable installation of the geological radar.

Specific embodiments

[0027] Please refer to Figures 1-7 , for further description of the embodiments of the present utility model;

[0028] A device for mine geological environment monitoring includes a surrounding frame 1;

[0029] A number of uniformly distributed mounting holes 2 are opened on the outer periphery of the bottom of the surrounding frame 1. At the top of each mounting hole 2, a first electric cylinder 7 is fixed. The output end of the first electric cylinder 7 is fixed with a positioning nail 6. The first electric cylinder 7 is used to drive the positioning nail 6 so that after the positioning nail 6 extends out of the mounting hole 2, it can drill into the soil of the hillside to position the surrounding frame 1. In the later stage, by starting the first electric cylinder 7, the positioning nail 6 can be removed from the figure, making the positioning and disassembly of the surrounding frame 1 more convenient. A number of longitudinally distributed side grooves 11 are opened on the outer side of the positioning nail 6, and elastic limit components are installed in each side groove 11. When the positioning nail 6 extends out of the mounting hole 2, the elastic limit components will pop out and penetrate into the soil to enhance the stability of the positioning nail 6 in the soil. A cross bar 3 is fixed inside the surrounding frame 1. The bottom of the cross bar 3 is elastically connected (such as through a spring or elastic member) with a protective sleeve 4 with an open bottom. The purpose of the elastic connection is to enable the protective sleeve 4 to fit the ground on mountain slopes with different gradients. A ground penetrating radar 5 is installed inside the protective sleeve 4. The protective sleeve 4 is used to protect the ground penetrating radar 5. The bottom of the ground penetrating radar 5 is flush with the bottom of the protective sleeve 4. The ground penetrating radar 5 is used to observe the ground, such as Figure 1As shown, the protective cover 4 is located inside the surrounding frame 1. Therefore, the surrounding frame 1 can further protect the ground penetrating radar 5. The cross bar 3 can be set to one or multiple, which can enhance the stability inside the surrounding frame 1, thus being able to better resist falling rocks.

[0030] As Figure 1 , 3 As shown in FIGS. 5, the top of the surrounding frame 1 is provided with jacks 15 that are the same in number and communicate with the mounting holes 2. A limiting frame 8 is provided above the surrounding frame 1. The limiting frame 8 is provided with a number of limiting feet 81. The limiting feet 81 respectively pass through a number of jacks 15 and then fit against the outer wall of the adjacent positioning pins 6. The limiting feet 81 are used for limiting by the elastic limiting components. Before the surrounding frame 1 is positioned, a number of limiting feet 81 on the limiting frame 8 respectively pass through a number of jacks 15 and then fit against the outer wall of the adjacent positioning pins 6. During this process, the elastic limiting components will be compressed into the corresponding side grooves 11, thereby limiting the elastic limiting components. When the first electric cylinder 7 is started, the limiting frame 8 is simultaneously driven into the soil, and it is ensured that the limiting frame 8 and the positioning pins 6 move down at the same speed. Thus, the limiting feet 81 on the limiting frame 8 can always limit the elastic limiting components. When the positioning pins 6 are positioned, the limiting frame 8 is lifted upward so that the elastic limiting components can drill into the soil. At this time, the elastic limiting components can enhance the stability of the positioning pins 6 in the soil. It should be noted that the limiting frame 8 is a steel frame with high hardness, which can extend the service life of the limiting frame 8. The limiting feet 81 are steel sheets with a thickness of 3 - 5 mm, and the lower end of the limiting feet 81 is a tip, which is convenient for the limiting feet 81 to quickly insert into the soil.

[0031] In order to reduce the workload of the staff and ensure that the limiting frame 8 and the positioning pins 6 move down at the same speed, a mounting seat 9 is fixed in the middle of the top of the cross bar 3. A second electric cylinder 10 with the same power as the first electric cylinder 7 is fixed inside the mounting seat 9. The output end of the second electric cylinder 10 passes through the mounting seat 9 and is detachably connected to the limiting frame 8 (such as bolt connection, snap connection, etc.). When the second electric cylinder 10 works, it will drive the limiting frame 8 to move down or up to achieve the purpose of limiting or releasing the limit of the elastic limiting components.

[0032] As Figure 1 , 2, as shown in FIGS. 4 and 6, the elastic limiting component includes a spring 12 and a limiting nail 13. The spring 12 is horizontally fixed in the side groove 11, and the limiting nail 13 is fixed to the outer end of the spring 12, and the tip of the limiting nail 13 is in contact with the limiting foot 81. The limiting foot 81 is used to limit the limiting nail 13. When the limiting nail 13 is separated from the limiting foot 81, the limiting nail 13 will be inserted into the soil under the elastic force of the spring 12. In order to facilitate the limiting foot 81 to press the limiting nail 13 into the side groove 11, an arc portion 131 is provided on the upper side of the tip of the limiting nail 13; in order to strengthen the friction and contact surface between the limiting nail 13 and the soil, a number of bumps 132 are welded to the tip of the limiting nail 13. It should be noted that the arc portion 131 is the upper side of the tip of the limiting nail 13 where no bumps 132 are provided to avoid affecting the normal entry and exit of the limiting nail 13.

[0033] A protective cover 14 is detachably connected to the top of the enclosure 1. The inner top of the protective cover 14 is detachably connected to the output end of the second electric cylinder 10 (such as bolt connection, snap connection, etc.). After the elastic limiting component is released from the limit, the limiting frame 8 will be moved above the enclosure 1 through the second electric cylinder 10. At this time, the staff can remove the limiting frame 8 from the second electric cylinder 10, then install the protective cover 14 at the output end of the second electric cylinder 10, and then drive the protective cover 14 to cover the top of the enclosure 1 by starting the second electric cylinder 10. At this time, under the use of the second electric cylinder 10, it is beneficial for the protective cover 14 to stably cover the enclosure 1, which can prevent sand and soil from entering the enclosure 1. The enclosure 1 also plays a certain role in guiding the sand and soil, and plays a good protective role for the protective sleeve 4 and the ground penetrating radar 5.

[0034] The working principle of this solution is as follows: When it is necessary to monitor a certain place on the mountain, the device is moved to the designated place and the ground penetrating radar 5 is made to fit the ground. The initial state of the device is as Figure 1 shown. Multiple limiting feet 81 are respectively inserted into multiple jacks 15 and limit multiple elastic limiting components. Subsequently, the second electric cylinder 10 and multiple first electric cylinders 7 are started simultaneously. The first electric cylinder 7 will drive the positioning nail 6 below it to move downward and gradually drill into the soil. At the same time, the second electric cylinder 10 will drive the limiting frame 8 to move downward, so that multiple limiting feet 81 respectively limit multiple elastic limiting components in real time, so as to prevent the elastic limiting component from popping out of the side groove 11 when the positioning nail 6 is not completely inserted into the soil;

[0035] After all the multiple positioning pins 6 are fully driven into the soil, close the multiple first electric cylinders 7. At the same time, make the second electric cylinder 10 move in the reverse direction to drive the limit frame 8 to move upward, so that multiple limit feet 81 can be moved above the enclosure 1. At this time, close the second electric cylinder 10, and the limit frame 8 can be disassembled from the output end of the second electric cylinder 10. Then, install the protective cover 14 at the output end of the second electric cylinder 10. Then, start the second electric cylinder 10 to drive the protective cover 14 to cover the top of the enclosure 1. At this time, with the use of the second electric cylinder 10, it is beneficial for the protective cover 14 to stably cover the enclosure 1. The enclosure 1 also plays a certain role in guiding the flow of sand and soil, which can prevent the sand and soil from directly falling on the protective sleeve 4 and the ground penetrating radar 5, playing a good protective role for the protective sleeve 4 and the ground penetrating radar 5. Therefore, the ground penetrating radar 5 can continue to be used normally even in rainy days;

[0036] During the upward movement of the limit feet 81, the positioning pins 13 are no longer limited. Therefore, the positioning pins 13 will pop out of the side grooves 11 under the action of the springs 12 and be driven into the soil, which can strengthen the stability of the positioning pins 6 in the soil and effectively avoid the situation that the installation of the ground penetrating radar 5 is unstable due to the loosening of the soil on the mountain during rainfall.
