DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a safety warning device for a mining slope, including an installation base 1. The installation base 1 includes a seat body 101. The bottom surface of the seat body 101 is provided with a bottom plate 102. A plurality of fixed installation holes 103 are evenly arranged around the upper surface of the bottom plate 102. The surface of the seat body 101 is provided with an auxiliary installation mechanism. One end of a column 2 is fixedly connected to the top surface of the seat body 101. A lifting mechanism 3 is slidably connected to the column 2. The lifting mechanism 3 is fixedly connected to two wire-pulling displacement sensors 4. The other end of the column 2 is provided with a mounting plate 5. A rain sensor 6 is fixedly installed on one side surface of the mounting plate 5. An audible and visual alarm 7 is fixedly installed on the surface of the mounting plate 5 on one side of the rain sensor 6. The wire-pulling displacement sensors 4 and the rain sensor 6 are both electrically connected to the audible and visual alarm 7.

[0021] Please refer to Figure 2 and Figure 3 , the seat body 101 is a regular polyhedron. The auxiliary installation mechanism includes a plurality of lifting chutes 104 opened on each side surface of the seat body 101 and extension chutes 105 corresponding to each lifting chute 104 on the upper surface of the bottom plate 102. A slider 106 is slidably connected in each lifting chute 104. An insertion limiting member 107 is slidably connected in each extension chute 105. Both ends of a connecting rod 108 are rotatably connected to the side surfaces of two corresponding sliders 106 and insertion limiting members 107. Each slider 106 is connected to an adjusting mechanism.

[0022] Setting the seat body 101 as a regular polyhedron can ensure that each lifting chute 104 can be evenly distributed circumferentially. When all the sliders 106 are driven to lift synchronously by the adjusting mechanism, all the inserted limit members 107 can be driven to lift synchronously through the drive of the connecting rod 108. Since each inserted limit member 107 is slidably connected to the corresponding extension chute 105, when the extension chute 105 descends, the inserted limit member 107 can extend below the bottom plate 102 through the extension chute 105 and thus insert into the slope body. The adjusting mechanism can adjust the insertion depth of the inserted limit member 107, thereby assisting in supporting and strengthening the overall installation, improving the stability of the overall installation. At the same time, in some temporary use scenarios, the whole can also be connected to the slope body without the cooperation of bolts and the fixed installation holes 103. Only through the auxiliary installation mechanism, the whole can also be installed temporarily, improving the convenience during use and reducing limitations.

[0023] Further, the adjusting mechanism includes a lifting frame 109 arranged outside the seat body 101. Each slider 106 is fixedly connected to the inner wall of the lifting frame 109 through a connecting member 110 arranged on one side surface. One end of an adjusting screw 111 is rotatably installed on the upper surface of the lifting frame 109. A first connecting plate 112 is arranged on one side surface of the seat body 101, and a threaded hole is penetrated through the upper surface of the first connecting plate 112. The adjusting screw 111 is threadedly connected in the threaded hole.

[0024] Each slider 106 is fixedly connected to the lifting frame 109 through the corresponding connecting member 110, and the adjusting screw 111 is threadedly connected in the threaded hole arranged on the surface of the first connecting plate 112. So when the adjusting screw 111 is rotated, its whole will displace up and down in the threaded hole, thereby driving the lifting frame 109 to lift up and down, and thus the length of the inserted limit member 107 extending out of the extension chute 105 can be controlled, and the depth of its insertion into the slope body can be adjusted, and flexible adjustment can be made according to the slope soil conditions and installation requirements.

[0025] Further, each inserted limit member 107 is a conical mechanism.

[0026] The conical structure can be more conducive to the insertion of one end of the inserted limit member 107 into the slope soil, making the operation more labor-saving.

[0027] Further, each extension chute 105 extends obliquely outward from the circumference of the bottom plate 102.

[0028] By setting the extension chute 105 with a certain inclination, it can be realized that during the downward extension of the inserted limit member 107, its angle will also extend outward from the circumference of the bottom plate 102 following the angle of the extension chute 105, expanding the contact area with the slope body and improving the stability of the overall support.

[0029] Please refer toFigure 4 The lifting mechanism 3 includes a lifting mounting block 301 which is slidably mounted on the column 2. Two wire-pulling displacement sensors 4 are respectively fixedly mounted on the two end surfaces of the lifting mounting block 301. A second connecting plate 302 is provided on one surface of the lifting mounting block 301. A screw hole is penetrated through the surface of the second connecting plate 302, and a lifting screw 303 is threadedly connected in the screw hole. One end of the lifting screw 303 is rotatably connected to the bottom surface of the mounting plate 5.

[0030] The lifting mounting block 301 is threadedly connected to the lifting screw 303 through the second connecting plate 302. By rotating the lifting screw 303, the whole lifting mounting block 301 can slide up and down on the column 2, so as to adjust the heights of the two wire-pulling displacement sensors 4. During use, according to the actual requirements, after adjusting the heights of the wire-pulling displacement sensors 4, the wire-pulling displacement sensors 4 can be used to give early warnings about the falling rocks on the slope. When relatively large falling rocks roll down from the slope body, they will pull the wires of the wire-pulling displacement sensors 4. After the wires are displaced by a predetermined length, the sound and light alarm 7 will give an early warning to the surrounding area, improving the safety in multi-scenario use.

[0031] Working principle: When long-term early warning of a certain position on the slope body is required, first pass the installation bolts through each fixed installation hole 103 and connect them to the slope body to complete the overall fixed installation. Then rotate the adjusting screw 111 to drive the lifting frame 109 to descend, so that all the sliders 106 descend synchronously, that is, all the inserted limit members 107 extend downward through the extension chute 105 and insert into the slope body to assist in supporting and strengthening the overall installation. When only temporary early warning of a certain position is required, the whole can be temporarily installed only through the inserted limit members 107 without fixing the whole through bolts, improving the convenience in the use process and reducing the limitations. After the overall installation, adjust the heights of the two wire-pulling displacement sensors 4 by rotating the lifting screw 303 according to the actual situation, and pull out and fix the wires of the two wire-pulling displacement sensors 4 to give early warnings about the falling rocks on the slope body. When there is a rainfall weather that is likely to cause danger, the rainfall sensor 6 can record the rainfall amount. When the rainfall amount exceeds the pre-set safe range, the rainfall sensor 6 can also start the sound and light alarm 7 to give an early warning to the surrounding area to remind people to take shelter.

[0032] It should be noted that the specific model specifications of the wire-pulling displacement sensor 4, the rainfall sensor 6 and the sound and light alarm 7 need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0033] The power supply and principle of the wire-pulling displacement sensor 4, the rainfall sensor 6 and the sound and light alarm 7 are clear to those skilled in the art and will not be elaborated here.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
