Description

Technical Field

[0001] The utility model relates to the technical field of slope monitoring, in particular to a mine slope deformation monitoring device with adjustable monitoring height. Background Art

[0002] Natural and human activities have caused great changes to the geological environment. In recent years, the frequency of geological disasters in my country has increased. The main disasters include landslides, mudslides, etc. There are many factors that induce geological disasters, such as rainfall, earthquakes, blasting, etc. Among them, the displacement of mine slopes is a major cause of mine geological disasters. Therefore, on the basis of effective real-time monitoring of the key factor of mine slope displacement, considering other disaster-inducing factors, it is possible to make a relatively accurate and timely prediction of the geological disasters caused by them. The occurrence of geological disasters can easily cause a large number of casualties and property losses. In order to reduce losses and monitor and warn of disasters, researchers in related fields have carried out a lot of geological disaster monitoring work.

[0003] At present, the existing open-pit metal mine slope monitoring equipment can only simply monitor the changes in the mine mountain at a single point, and cannot perform multi-parameter monitoring of slope changes; for example, the utility model patent (application number is CN202111512196.9) discloses a slope soil pressure monitoring device, which sets a first axis, a first protrusion, a first fixed block, a first elastic member and a second fixed block, moves the first axis to drive the first fixed block to move, and the first fixed block drives the second fixed block to move, further compresses the first elastic member, thereby fixing the main body and the soil together, and performing slope soil pressure monitoring; after use, when taking it out, you only need to move the first axis, and the first elastic member drives the second fixed block to move so that the main body and the second fixed block are no longer fixed, and then take out the main body.

[0004] The displacement and deformation of mine slopes are often affected by multiple factors, and multiple monitoring devices need to be set up for monitoring. However, the use of multiple monitoring devices will increase costs, and be inconvenient to install and use. In addition, the flatness of mine slopes is low, which makes the height difference of the monitoring points large, so the monitoring height requirements of monitoring equipment are high. In addition, metal mine slopes are affected by mining and are prone to rockfall and landslides. Existing slope monitoring equipment is easily damaged by rockfall and has no function of protecting the equipment, resulting in a short service life of the monitoring equipment, which also increases the monitoring cost.

[0039] Example

[0040] See also Figure 1 to Figure 3 As shown, a mine slope deformation monitoring device 100 with adjustable monitoring height includes a slope pressure monitoring device, a soil settlement monitoring device 110 and a mounting rod 120 connecting the two. The slope pressure monitoring device is slidably connected to the rod body of the mounting rod 120, the soil settlement monitoring device 110 is fixedly connected to the bottom end of the mounting rod 120, and the monitoring platforms of the slope pressure monitoring device and the soil settlement monitoring device 110 are arranged facing the same direction; a turning handle 125 is provided on the outside of the rod body of the mounting rod 120, and a transmission assembly connected to the slope pressure monitoring device is provided on the inside, and a rotating shaft 126 connecting the turning handle 125 and the transmission assembly is provided between the turning handle 125 and the transmission assembly, so as to control the transmission assembly through the turning handle 125 and adjust the height of the slope pressure monitoring device on the mounting rod 120. The utility model of the slope multi-parameter monitoring device combines the slope pressure monitoring device with the soil settlement monitoring device 110 to monitor the soil landslide and settlement of the metal mine slope in real time. At the same time, a buffer unit 150 is provided to protect the equipment, thereby extending the service life of the equipment and reducing the monitoring cost.

[0041] See also Figure 4-5 As shown, the slope pressure monitoring device includes a displacement monitoring unit 130, a pressure monitoring unit 140 and a buffer unit 150, and the buffer unit 150 plays a protective role on the equipment. The slope pressure monitoring device also includes a pressure transmission plate 160, a mounting plate 170 connected to the pressure transmission plate 160, and a first connecting plate 180 slidably connected to the mounting rod 120. The displacement monitoring unit 130, the pressure monitoring unit 140 and the buffer unit 150 are all arranged between the mounting plate 170 and the first connecting plate 180, and the pressure transmission plate 160 is a monitoring platform for the slope pressure monitoring device. In addition, the displacement monitoring unit 130 and the buffer unit 150 are generally arranged in groups, the displacement monitoring unit 130 is connected to the mounting plate 170, the buffer unit 150 is connected to the first connecting plate 180, and the displacement monitoring unit 130 and the buffer unit 150 are movably connected through components, such as a sliding rod 131 and a buffer plate 152, to achieve force transmission.

[0042] See also Figure 8As shown, the installation rod 120 has an installation cavity 121 for installing the transmission assembly inside, and the transmission assembly includes a threaded rod 122 that rotates relative to the installation cavity 121, a threaded sleeve 123 sleeved on the threaded rod 122, and the threaded sleeve 123 is fixedly connected to the first connecting plate 180; a limiting groove 124 is provided on the side of the installation rod 120 connected to the slope pressure monitoring device, and the threaded sleeve 123 and the first connecting plate 180 are both slidably connected to the limiting groove 124, and the threaded rod 122 rotates to drive the threaded sleeve 123 to move along the threaded rod 122, so that the first connecting plate 180 slides relative to the limiting groove 124. The transmission assembly also includes an active bevel gear 127 fixedly connected to the end of the rotating shaft 126, and a driven bevel gear 128 meshing with the active bevel gear 127, and the driven bevel gear 128 is fixedly installed on the upper end of the threaded rod 122. In this way, the rotation of the handle 125 can drive the rotation of the rotating shaft 126, the active bevel gear 127 and the driven bevel gear 128, and the driven bevel gear 128 drives the threaded rod 122 to rotate, and then the threaded rod 126 controls the threaded sleeve block 123 and the first connecting plate 180 to slide relative to the limit groove 124, thereby realizing manual adjustment of the height of the slope pressure monitoring device. By setting a component that enables the slope pressure monitoring device to move relative to the installation rod 120, the device can adjust the installation depth of the device according to different needs, and then flexibly adjust the height of the slope pressure monitoring device and its monitoring platform, making the device more practical.

[0043] Specifically, the buffer unit 150 includes a buffer box 151 fixedly connected to the first connecting plate 180, and a buffer plate 152 and a plurality of parallel buffer springs 153 are sequentially arranged in the buffer box 151. The buffer plate 152 is arranged in contact with the side of the buffer box 151 away from the first connecting plate 180, and the outer surface of the side is also provided with a displacement slide groove 154; the displacement monitoring unit 130 includes two slide rods 131 whose ends are connected to the side of the mounting plate 170, and two connecting rods 132 movably connected to the middle of the mounting plate 170. The slide rod 131 passes through the buffer box 1 51, connected to the buffer plate 152 inside the buffer box 151, the other end of the two connecting rods 132 is movably connected with a slider 133, the slider 133 is slidably connected to the displacement slide 154, and the two connecting rods 132 form a movable triangular structure between the buffer box 151 and the mounting plate 170 through the slider 133; the displacement monitoring unit 130 also includes a soil fiber Bragg grating strain sensor 134 arranged in the displacement slide 154, and two tension and compression sensing rods 135 respectively connecting the soil fiber Bragg grating strain sensor 134 and the two sliders 133. It should be noted that the connecting rod 132 is movably connected to the mounting plate 170 and the slider 131 through a hinge.

[0044] When a landslide occurs on the slope of a metal mine, the force on the pressure transmission plate 160 increases and causes displacement, which is transmitted to the connecting rod 132 and the sliding rod 131 through the mounting plate 170. The sliding rod 131 is displaced relative to the buffer box 151, shortening the distance between the mounting plate 170 and the buffer box 150, thereby changing the angle of the two connecting rods 132 of the hinged connection, driving the two sliders 133 to slide to the sides of the displacement slot 154, so that the tension and compression sensing rod 135 generates tension on the soil fiber grating strain sensor 134, thereby monitoring the change in displacement. In addition, the pressure transmission plate 160, as a monitoring platform of the slope pressure monitoring device, needs to be set facing the top of the slope to accurately monitor the deformation of the slope. However, such a setting is easily affected by falling rocks from landslides, and the falling rocks cause great damage to the device. When falling rocks roll down to the pressure transmission plate 160 of the utility model, the pressure transmission plate 160 is subjected to impact force, and the slide bar 131 is displaced relative to the buffer box 151, pushing the buffer plate 152 in the buffer box 151, and the buffer plate 152 squeezes the buffer spring 153. The buffer plate 152, the buffer box 151, and the buffer spring 153 cooperate with each other to buffer the impact force generated by the falling rocks, thereby protecting the equipment.

[0045] See also Figure 6 As shown, the pressure monitoring unit 140 includes a pressure transmission rod 141, a pressure sensor 142, a mounting seat 143 and a spring 144 connected in sequence, and also includes a box body 145 for mounting the spring 144. The end of the pressure transmission rod 141 away from the pressure sensor 142 is fixedly connected to the mounting plate 170, and the end of the box body 144 away from the mounting seat 143 is connected to the first connecting plate 180. Guide grooves 146 are provided on both sides of the box body 145, and guide plates 147 are fixedly connected on both sides of the mounting seat 143, and the guide plates 147 are slidably connected to the guide grooves 146; in this way, the mounting seat 143 drives the pressure transmission rod 141 and the pressure sensor 142 to slide relative to the box body 145 through the guide plates 147. When the pressure transmission plate 160 is subjected to the force generated by the landslide of the metal mine slope, the force will be transmitted to the mounting plate 170, the pressure transmission rod 141 and the pressure sensor 142 in sequence. The pressure sensor 142 can sense the change of stress and realize stress monitoring; at the same time, by arranging a box body 145 for installing the spring 144 and a guide plate 147 and a guide groove 146 for realizing a sliding connection at the other end of the pressure sensor 142, the stress of the pressure sensor 142 during operation can be relieved, the fatigue degree of the internal components of the pressure sensor 142 can be reduced, and the service life of the device can be extended.

[0046] In this way, when the soil on the slope of a metal mine becomes loose and a landslide occurs, the pressure monitoring unit 140 senses the change in pressure, and the displacement monitoring unit 130 senses the change in displacement, thereby achieving accurate monitoring of the landslide of the slope soil; at the same time, the force transmitted by the pressure transmission plate 160 can also be transmitted to the buffer unit 150, thereby preventing damage to the equipment due to falling rocks, and the buffer unit 150 buffers the impact force generated by the falling rocks, thereby effectively protecting the equipment.

[0047] See also Figure 7 As shown, the soil settlement monitoring device 110 includes a plurality of soil settlement monitoring shells 111 connected in sequence, a slope settlement sensing plate 112 arranged on the soil settlement monitoring shells, and a soil settlement monitoring unit 117 arranged inside the soil settlement monitoring shells 111. The plurality of soil settlement monitoring shells 111 are arranged in sequence along the extension direction of the bottom end of the mounting rod 120; the slope settlement sensing plates 111 are oriented in the same direction, serving as a monitoring platform for the soil settlement monitoring device 110. The device is provided with a soil settlement monitoring device 110 that can be pre-buried in the soil of the slope to accurately sense the settlement of the soil on the slope. The soil settlement monitoring device 110 can prevent soil from entering and blocking the device, affecting the monitoring effect, and its transmission structure is more stable, thereby improving the accuracy of monitoring the soil settlement of the slope of the metal mine.

[0048] Specifically, an outer slide plate 113 fixedly connected to the slope settlement sensing plate 112 is provided between the slope settlement sensing plate 112 and the soil settlement monitoring shell 111; a pin groove 114 is provided on the side of the soil settlement monitoring shell 111 that contacts the outer slide plate 113, and a sliding pin 115 slidably connected to the pin groove 114 is provided in the pin groove 114; an inner slide plate 116 is provided inside the soil settlement monitoring shell 111, and the inner slide plate 116 contacts the side of the soil settlement monitoring shell 113 where the pin groove 114 is provided, and the sliding pin 115 is fixedly connected between the outer slide plate 113 and the middle part of the inner slide plate 116; the length of the pin groove 114 on the surface of the soil settlement monitoring shell 111 is less than 1 / 2 times the length of the outer slide plate 113. In this way, the outer slide plate 113 and the inner slide plate 116 can realize movement relative to the pin slide groove 114 through the sliding pin 115. At the same time, the cooperation between the outer slide plate 113 and the pin slide groove 114 can prevent soil from entering the soil settlement monitoring shell 111 through the pin slide groove 114, resulting in blockage of the pin slide groove 114 by the soil, thereby ensuring the feasibility of burying the soil settlement monitoring device 110 inside the slope soil and improving the accuracy of slope settlement monitoring.

[0049] The soil settlement monitoring unit 117 includes a guide rod 1171 with both ends fixed on the soil settlement monitoring shell 111, a sleeve 1172 slidably mounted on the guide rod 1171, a fixed support rod 1173 fixedly connected to the middle of the sleeve 1172, and a settlement soil tension and compression sensing rod 1174 vertically connected to the fixed support rod 1173; both ends of the settlement soil tension and compression sensing rod 1174 are fixedly connected to the soil settlement monitoring shell 111, and the settlement soil tension and compression sensing rod 1174 is symmetrically arranged with the fixed support rod 1173 as the center and settlement soil fiber grating strain sensors 1175 on both sides; the soil settlement monitoring unit 117 also includes a first rack 1176 fixedly connected to the inner slide 116, a transmission gear 1177 meshing with the first rack 1176, and a second rack 1178 arranged on one side of the sleeve 1172, and the second rack 1178 is meshing with the transmission gear 1177.

[0050] In this way, when the slope soil settles, the slope settlement sensing plate 112 will be displaced, thereby driving the outer slide plate 113, the sliding pin 115, the inner slide plate 116 and the first rack 1176 to be displaced, and then the second rack 1178, the sliding sleeve 1172, the fixed support rod 1173 and the settlement soil tension and compression sensing rod 1174 are driven to be displaced through the transmission gear 1177, and the two settlement soil fiber grating strain sensors 1175 sense it, so as to realize accurate monitoring of soil settlement. In addition, compared with the rope structure in the prior art, the gear transmission structure of the soil settlement monitoring device 110 is more stable, has a longer service life after being buried in the soil, and will not slip, and the transmission effect is more stable and accurate.

[0051] The mine slope deformation monitoring device 100 with adjustable monitoring height also includes a power supply integrated unit, which is signal-connected to the slope pressure monitoring device and the soil settlement monitoring device 110; the power supply integrated unit and the soil settlement monitoring device 110 are arranged in the same monitoring box 190, and the monitoring box 190 is fixedly connected to the bottom end of the mounting rod 120. The mine slope deformation monitoring device 100 with adjustable monitoring height also includes a Beidou receiver 1201 arranged on the top of the mounting rod 120 and an intelligent ball camera 1202 arranged on one side of the mounting rod 120. The Beidou receiver 1201 and the intelligent ball camera 1202 can monitor image parameters or target position movement, and then obtain the deformation of the slope.
