Description

Technical Field

[0001] The present invention relates to the technical field of geological engineering, mining engineering and environmental monitoring, and in particular to an automatic monitoring and early warning device for mining geological disasters. Background Art

[0002] Mining geological disasters mainly include collapse, landslide, mud-rock flow, etc. These disasters not only threaten the life and safety of mining workers, but also may cause equipment damage, production interruption and economic losses. In addition, geological disasters will also have irreversible impacts on the surrounding environment, including soil erosion and ecological damage.

[0003] The application number 202210509684.2 disclosed an automatic monitoring and early warning device for mining geological disasters, including a bracket and a shell installed with the bracket, a mounting groove is provided at one end of the shell, a transparent protective plate is provided at the notch of the mounting groove, and a trapezoidal mounting plate is symmetrically fixedly installed on the lower surface of the protective plate; the lower surface of the shell is provided with two groups of locking assemblies for locking two mounting plates respectively, and a placement plate is fixedly installed on the lower surface of the shell through a support rod, and the locking assembly includes a spring rod vertically fixedly installed on the upper surface of the placement plate and a trapezoidal mounting block fixedly installed on the top of the spring rod, and the top ends of the two spring rods are respectively inserted into two slots, and the lower surfaces of the two mounting blocks are provided with locking grooves for the mounting blocks to enter. This technical solution can quickly realize the installation and disassembly of the protective plate and the shell through the locking assembly, avoiding the cumbersome steps of using screw and nut fixings.

[0004] The above technical solution has the same defects as the traditional surveillance camera during installation and use. The monitoring device is installed at a fixed position. After installation, the height of the device cannot be adjusted. This installation method has many problems and defects:

[0005] 1. If the height of the monitoring and early warning camera equipment cannot be adjusted arbitrarily, it will be impossible to flexibly adjust the distribution height of the monitoring and early warning camera equipment according to the terrain and geological characteristics of different parts of the mine. The equipment will find it difficult to adapt to changes in the environment, resulting in some key areas that may not be monitored in place. Due to the fixed monitoring height, the geological data collected by the equipment will be limited and unable to provide multi-dimensional and multi-level information, which may affect the accuracy of geological analysis and the reliability of decision-making.

[0006] 2. If multiple possible height requirements are taken into consideration during equipment installation, it may be necessary to design redundant brackets in advance or select a more complex installation solution, which will increase the cost and complexity of the initial installation of the equipment. In the subsequent use process, if the equipment has to be readjusted due to changes in terrain or monitoring requirements, the fixed height design will lead to frequent equipment disassembly and reset, increasing maintenance and operating costs, which is not conducive to the efficient operation of the mine monitoring system.

[0007] To this end, we propose an automatic monitoring and early warning device for mining geological disasters. Summary of the invention

[0024] Beneficial Effects

[0025] The present invention provides an automatic monitoring and early warning device for mining geological disasters. It has the following beneficial effects:

[0026] (1) In this automatic monitoring and early warning device for geological disasters in mines, the monitoring and early warning camera equipment is arranged on a lifting seat. By controlling the vertical chain transmission, the vertical chain drives the lifting seat to rise and fall, thereby facilitating the adjustment of the distribution height of the monitoring and early warning camera equipment. By flexibly adjusting the distribution height of the monitoring and early warning camera equipment according to the topographical and geological characteristics of different sections of the mine, the monitoring and early warning camera equipment can be better adapted to environmental changes. The height-adjustable design of the monitoring and early warning camera equipment reduces the frequency of equipment reset and reinstallation, and reduces maintenance and operating costs. The data collected by the monitoring and early warning camera equipment at different heights can provide more comprehensive geological information and support more in-depth analysis and decision-making.

[0027] (2) In the automatic monitoring and early warning device for mining geological disasters, in the initial state, the electromagnetic rod is in a power-off and demagnetized state, and the tension spring on the tension spring rod pulls the locking block to expand outward. At this time, the diameter of the slide slot is relatively large, and the slide slot sleeve is distributed on the electromagnetic rod. When the slide slot diameter is relatively large, a gap is formed between the inner wall surface of the slide slot and the outer wall surface of the electromagnetic rod. At this time, the battery box is suspended. By controlling the vertical chain transmission, the vertical chain can freely drive the monitoring and early warning camera equipment to adjust its position up and down. When the monitoring and early warning camera equipment is adjusted to a suitable monitoring height, the electromagnetic rod is controlled to be magnetized. After the electromagnetic rod is magnetized, it acts on the locking block. Due to the effect of magnetic adsorption, multiple groups of locking blocks are close to each other and tightly adsorbed and fixed on the electromagnetic rod. They are clamped and fixed on the electromagnetic rod through the magnetic locking mechanism, so that the magnetic locking mechanism and the battery box are distributed in a relatively fixed state, and the battery box will be relatively fixed with the lifting seat. At this time, external factors such as environmental wind will not be able to drive the lifting seat to shake, so that the lifting seat with the monitoring and early warning camera equipment is stably distributed at the adjusted height. Through this design, the monitoring system can better adapt to complex environmental conditions and provide clearer and more stable monitoring effects at different heights, effectively improving the overall efficiency of the monitoring operation.

[0028] (3) This automatic monitoring and early warning device for mining geological disasters has a serious working environment with dust and sand. When the monitoring and early warning camera equipment needs to be cleaned, the electromagnetic rod is controlled to be powered off and demagnetized. At this time, the vertical chain can descend with the monitoring and early warning camera equipment, thereby achieving the effect of making it convenient for people to clean and maintain the monitoring and early warning camera equipment.

[0029] (4) This automatic monitoring and early warning device for mining geological disasters realizes that the rotation directions of the two sets of pulleys are set in opposite directions by arranging the transmission belts in a cross shape. Since the rotation directions of the two sets of pulleys are opposite, the two sets of pulleys can synchronously lift and lower the corresponding vertical transmission mechanisms. The setting of the change-of-direction transmission mechanism facilitates the simultaneous control of the lifting and lowering of the two sets of vertical transmission mechanisms, avoiding the need to use multiple drive sources to control the two sets of vertical transmission mechanisms, thereby achieving the effect of reducing energy loss.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1: A mine geological disaster automatic monitoring and early warning device, referring to Figure 1 and Figure 2 , including a control base 1 and a monitoring and early warning camera device 9, the left and right sides of the control base 1 are provided with mounting plates 2, the mounting plates 2 are provided with anchor holes, a support vertical plate 3 is fixedly installed on the control base 1 vertically upward, and a top plate 16 is fixedly installed at the front and rear sides of the support vertical plate 3 near the upper end surface, and multiple groups of electromagnetic rods 4 are fixedly installed between the control base 1 and the top plate 16, an iron core is arranged inside the electromagnetic rod 4 and an electromagnetic coil is wound on the iron core, a power supply module is arranged inside the control base 1, and both ends of the electromagnetic coil are connected to the power supply module, and the magnetic field generated when the current passes through the coil will make the electromagnetic rod 4 electromagnetic, so that the electromagnetic rod 4 has an attraction, and when the electromagnetic coil on the iron core in the electromagnetic rod 4 is powered off, the electromagnetic rod 4 loses its magnetic characteristics, and multiple groups of electromagnetic rods 4 are symmetrically distributed on the front and rear sides of the support vertical plate 3;

[0043] Further, see Figure 1 and Figure 3 The top surface of the control base 1 is fixedly installed with a left-right symmetrical lower side plate 5, and the front and rear sides of the support vertical plate 3 are fixedly installed with a left-right symmetrical upper side plate 6, the upper side plate 6 is distributed near the upper end of the support vertical plate 3, and the front and rear sides of the support vertical plate 3 are both provided with a vertical transmission mechanism 7;

[0044] Among them, refer to Figure 3 and Figure 4 The vertical transmission mechanism 7 includes a vertical chain 701. A transmission shaft 700 is rotatably installed between two groups of lower side plates 5 that are symmetrical on the left and right. A transmission shaft 700 is also rotatably installed between two groups of upper side plates 6 that are symmetrical on the left and right. A sprocket wheel 702 is fixedly installed on the transmission shaft 700. The inner wall surface of the vertical chain 701 is provided with equidistantly arranged sprocket teeth 703. The outer surface of the sprocket wheel 702 is provided with tooth grooves that are structured to match the sprocket teeth 703. The vertical chain 701 is installed between the two groups of symmetrical sprocket wheels 702. By controlling any group of transmission shafts 700 to rotate, the transmission shaft 700 drives the corresponding vertical chain 701 to transmit.

[0045] Further, see Figure 1 and Figure 4 The outer side of the vertical chain 701 is fixedly installed with an L-shaped lifting seat 8, and the monitoring and early warning camera equipment 9 is arranged on the lifting seat 8. By controlling the transmission of the vertical chain 701, the vertical chain 701 drives the lifting seat 8 to rise and fall, so as to facilitate the adjustment of the distribution height of the monitoring and early warning camera equipment 9. By flexibly adjusting the distribution height of the monitoring and early warning camera equipment 9 according to the topographical and geological characteristics of different sections of the mine, it is better to adapt to environmental changes. The height-adjustable design of the monitoring and early warning camera equipment 9 reduces the frequency of equipment reset and reinstallation, and reduces maintenance and operating costs. Secondly, the data collected by the monitoring and early warning camera equipment 9 at different heights can provide more comprehensive geological information and support more in-depth analysis and decision-making;

[0046] Further, see Figure 4 A power storage box 10 is fixedly installed on the side of the lifting seat 8 away from the monitoring and early warning camera device 9. A power module is also provided in the power storage box 10. A power line 11 is fixedly installed on the monitoring and early warning camera device 9. The power line 11 is fixedly connected to the power module inside the power storage box 10, and the power module in the power storage box 10 provides power to the monitoring and early warning camera device 9;

[0047] Embodiment 2: A mine geological disaster automatic monitoring and early warning device, based on the embodiment 1, referring to Figure 4 and Figure 5The lifting seat 8 is fixedly mounted on the vertical chain 701, and the lifting and lowering of the lifting seat 8 is controlled by the transmission action of the vertical chain 701. Although the vertical chain 701 itself is made of hard material, it has certain flexibility in function and application. Therefore, the lifting seat 8 carrying the monitoring and early warning camera device 9 on the vertical chain 701 has poor stability and is prone to swing with environmental wind and other conditions. The swing will make the image captured by the monitoring and early warning camera device 9 unstable and blurred, thereby affecting the accuracy of the monitoring data. Therefore, a plurality of groups of through openings 15 are provided through the battery box 10, and the through openings 15 are coaxially arranged with the electromagnetic rod 4. The plurality of groups of electromagnetic rods 4 pass through the corresponding through openings 15, and a magnetic locking mechanism 12 for cooperating with the electromagnetic rod 4 for tightening is provided inside the through openings 15;

[0048] Further, see Figure 5 The magnetic locking mechanism 12 includes multiple sets of locking blocks 120 and tension spring rods 121. The multiple sets of tension spring rods 121 are fixedly installed on the inner wall surface of the through hole 15. The multiple sets of tension spring rods 121 are distributed in a circular array with the center of the through hole 15 as the center. The multiple sets of locking blocks 120 are slidably installed on the tension spring rods 121. The multiple sets of locking blocks 120 are also distributed in a circular array with the center of the through hole 15 as the center. The side of the multiple sets of locking blocks 120 close to the center of the through hole 15 is an arc surface. The side of the multiple sets of locking blocks 120 close to the center of the through hole 15 is mutually locked. The slide groove 122 is formed close to each other. In the initial state, the electromagnetic rod 4 is in a power-off demagnetization state. The tension spring on the tension spring rod 121 pulls the locking block 120 to expand outward. At this time, the diameter of the slide groove 122 is relatively large. The slide groove 122 is sleeved and distributed on the electromagnetic rod 4. When the diameter of the slide groove 122 is relatively large, a gap is formed between the inner wall surface of the slide groove 122 and the outer wall surface of the electromagnetic rod 4. At this time, the power storage box 10 is suspended. By controlling the transmission of the vertical chain 701, the vertical chain 701 can freely drive the monitoring and early warning camera device 9 to adjust up and down. Position, when the monitoring and early warning camera device 9 adjusts the appropriate monitoring height, the control electromagnetic rod 4 is electromagnetized, and the electromagnetic rod 4 is magnetized to magnetically absorb the locking block 120, and multiple groups of locking blocks 120 are close to each other and tightly absorbed and fixed on the electromagnetic rod 4, and are tightly fixed on the electromagnetic rod 4 through the magnetic locking mechanism 12, so that the magnetic locking mechanism 12 and the power storage box 10 are distributed in a relatively fixed state, and the power storage box 10 will be relatively fixed with the lifting seat 8. At this time, external factors such as environmental wind force will not be able to drive the lifting seat 8 to shake, so that the lifting seat 8 and the monitoring and early warning camera device 9 are stably distributed at the adjusted height, thereby improving the stability of the monitoring and early warning camera device 9 during monitoring operations, and improving the clarity of the images captured by the monitoring and early warning camera device 9. Since the monitoring and early warning camera device 9 is in a working environment with severe wind, sand and dust, when the monitoring and early warning camera device 9 needs to be cleaned, the control electromagnetic rod 4 is powered off and demagnetized, and at this time the vertical chain 701 can descend with the monitoring and early warning camera device 9, which is convenient for people to clean and maintain the monitoring and early warning camera device 9;

[0049] Embodiment 3: A mine geological disaster automatic monitoring and early warning device, based on the embodiment 1, referring to Figure 6 A motor box 14 is provided on one side of the control base 1 and a driving motor is provided in the motor box 14. The output end of the driving motor in the motor box 14 is fixedly connected to a group of transmission shafts 700 located below. The corresponding transmission shaft 700 is controlled to rotate by the motor box 14, so that the transmission shaft 700 drives the corresponding vertical chain 701 for transmission. Since vertical transmission mechanisms 7 are provided on both the front and rear sides of the supporting vertical plate 3, it is necessary to control the two groups of vertical transmission mechanisms 7. The outer side surface of the lower side plate 5 is provided with a change-of-direction transmission mechanism 13 for controlling the synchronous transmission of the two groups of vertical transmission mechanisms 7;

[0050] Further, see Figure 6 The direction-changing transmission mechanism 13 includes a linkage shaft 130 and a pulley 131. The linkage shaft 130 is rotatably mounted on the lower side plate 5. The pulley 131 is fixedly mounted on the outer end of the linkage shaft 130. The pulley 131 is distributed on the outer side of the lower side plate 5. The end of the linkage shaft 130 away from the pulley 131 is fixedly connected to the corresponding transmission shaft 700. A belt groove 132 is opened at the outer circle of the pulley 131. A cross-arranged transmission belt 133 is installed between the two sets of pulleys 131 through the belt groove 132 for transmission. By arranging the transmission belt 133 in a cross shape, the rotation directions of the two sets of pulleys 131 are opposite. Since the rotation directions of the two sets of pulleys 131 are opposite, the two sets of pulleys 131 bring the corresponding vertical transmission mechanism 7 to rise and fall synchronously. The direction-changing transmission mechanism 13 is convenient to simultaneously control the lifting and lowering of the two sets of vertical transmission mechanisms 7, avoiding the need to use multiple drive sources to control the two sets of vertical transmission mechanisms 7, thereby reducing energy loss.

[0051] Working principle of the present invention:

[0052] The monitoring and early warning camera equipment 9 is arranged on the lifting seat 8. By controlling the transmission of the vertical chain 701, the vertical chain 701 drives the lifting seat 8 to rise and fall, thereby facilitating the adjustment of the distribution height of the monitoring and early warning camera equipment 9.

[0053] In the initial state, the electromagnetic rod 4 is in a power-off demagnetization state, and the tension spring on the tension spring rod 121 pulls the locking block 120 to expand outward. At this time, the diameter of the slide groove 122 is relatively large, and the slide groove 122 is arranged and distributed on the electromagnetic rod 4. When the diameter of the slide groove 122 is relatively large, a gap is formed between the inner wall surface of the slide groove 122 and the outer wall surface of the electromagnetic rod 4. At this time, the power storage box 10 is suspended. By controlling the transmission of the vertical chain 701, the vertical chain 701 can freely drive the monitoring and early warning camera device 9 to adjust its position up and down. When the monitoring and early warning camera device 9 adjusts the appropriate monitoring height, the electromagnetic rod 4 is controlled to be electromagnetized. After the electromagnetic rod 4 is magnetized, it has a magnetic adsorption effect on the locking block 120. Multiple groups of locking blocks 120 are close to each other and tightly adsorbed and fixed on the electromagnetic rod 4. They are tightly fixed on the electromagnetic rod 4 through the magnetic locking mechanism 12, so that the magnetic locking mechanism 12 is distributed with the power storage box 10 in a relatively fixed state, and the power storage box 10 will be relatively fixed with the lifting seat 8.

[0054] By arranging the transmission belts 133 in a cross shape, the rotation directions of the two sets of pulleys 131 are set oppositely. Since the rotation directions of the two sets of pulleys 131 are opposite, the two sets of pulleys 131 can be raised and lowered synchronously with the corresponding vertical transmission mechanism 7.

[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
