Description

Technical Field

[0001] This application relates to the field of monitoring device technology, and in particular to underground safety monitoring devices for mines. Background Technology

[0002] In the underground working environment of mines, safety monitoring devices are key equipment to ensure production safety and prevent accidents. Currently, most mine safety monitoring devices widely used in the market are installed on the walls or supports of the mine by bolting or welding. Although these devices meet basic monitoring needs to a certain extent, there are many inconveniences in the installation, disassembly, and subsequent update and maintenance processes. Bolting requires professional personnel to install and disassemble with tools, which is time-consuming and cumbersome. Especially in the space-constrained and harsh environment of mines, it increases the difficulty of operation and safety hazards. Although welding provides a firm fixation, cutting is required when updating or repairing the monitoring device. This is not only time-consuming and labor-intensive, but may also damage the equipment and increase maintenance costs.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the issue that most mine safety monitoring devices currently on the market are installed on mine walls or supports using bolts or welding, while these devices meet basic monitoring needs to some extent, they present numerous inconveniences during installation, disassembly, and subsequent updates and maintenance. Bolt installation requires professional personnel with tools, which is time-consuming and cumbersome, especially in the space-constrained and harsh environment of mines, further increasing the difficulty of operations and safety hazards. Although welding provides a secure fixation, it requires cutting operations when updating or repairing the monitoring device, which is not only time-consuming and labor-intensive but may also damage the equipment and increase maintenance costs. This application provides a mine underground safety monitoring device.

[0005] The underground safety monitoring device for mines provided in this application adopts the following technical solution:

[0006] A mine underground safety monitoring device includes a fixed plate, a column fixedly connected to the left side of the fixed plate, a motor installed at the lower end of the column, multiple screw holes on the fixed plate, a sliding groove inside the column, a trapezoidal threaded rod rotatably connected between the upper and lower inner walls of the sliding groove, the end of the motor's output shaft extending into the sliding groove and fixedly connected to one end of the trapezoidal threaded rod, and an installation mechanism for the monitoring device provided on one side of the column.

[0007] Preferably, a slider is threadedly connected to the trapezoidal threaded rod, the slider is slidably connected to the left and right inner walls of the groove, and a rectangular block is fixedly connected to the left side of the slider.

[0008] Preferably, the installation mechanism includes a limiting groove formed within a rectangular block, a sliding plate slidably connected between the upper and lower inner walls of the limiting groove, and the sliding plate being elastically connected to the right inner wall of the limiting groove via two compression springs.

[0009] Preferably, a wedge-shaped block is horizontally arranged in the limiting groove, a pull rod is fixedly connected to the upper end of the wedge-shaped block, the upper end of the pull rod extends to the upper end of the rectangular block and is fixedly connected to a pull plate, a pull ring is fixedly connected to the upper end of the pull plate, and the lower end of the pull plate is elastically connected to the upper end of the rectangular block through two connecting springs.

[0010] Preferably, a connecting block is provided on one side of the rectangular block, and a wedge-shaped groove is provided at the upper end of the connecting block to cooperate with the wedge-shaped block.

The sensing component includes a methane, carbon monoxide, temperature, and dust sensor.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The fixing plate is installed on the inner wall of the mine using multiple bolts. Then, the connecting block is inserted into the rectangular block. When the connecting block passes the wedge block, it will push the wedge block upward. When the wedge block reaches the wedge groove, it will be engaged in the wedge groove by the elastic action of two connecting springs, thus completing the installation. The installation mechanism enables quick connection without the need for bolts or welding. Installation can be achieved with simple operation.

[0014] 2. Under the elastic action of the compression spring, the sliding plate will exert a force to the left on the connecting block, which, in conjunction with the limiting action of the wedge block, makes the connecting block more tightly limited. When disassembly is required, the pull plate can be pulled upward, and the wedge block will be moved upward through the pull rod, so that the wedge block leaves the wedge groove. At this time, under the elastic action of the two compression springs, the sliding plate will quickly move to the left, so that the two fixed structures can be quickly separated. This installation mechanism greatly simplifies the installation and disassembly process, reduces the difficulty of operation and safety hazards, improves work efficiency, and also improves the convenience and efficiency of maintenance.

[0015] 3. During normal use, the device can be adjusted by starting the motor, which will drive the trapezoidal threaded rod to rotate. This will cause the slider connected to the rod to move the rectangular block, camera, and sensing components up or down. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses an underground safety monitoring device for mines. (Refer to...) Figure 1-3 The underground safety monitoring device for mines includes a fixed plate 1, a column 2 fixedly connected to the left side of the fixed plate 1, a motor 9 installed at the lower end of the column 2, multiple screw holes on the fixed plate 1, a sliding groove inside the column 2, a trapezoidal threaded rod 8 rotatably connected between the upper and lower inner walls of the sliding groove, the end of the output shaft of the motor 9 extends into the sliding groove and is fixedly connected to one end of the trapezoidal threaded rod 8, and an installation mechanism for the monitoring device is provided on one side of the column 2.

[0022] The fixing plate 1 is installed on the inner wall of the mine by multiple bolts. Then the connecting block 5 is inserted into the rectangular block 3. When the connecting block 5 passes the wedge block 16, it will push the wedge block 16 upward. When the wedge block 16 reaches the wedge groove 14, it will be inserted into the wedge groove 14 by the elastic action of the two connecting springs 7, thus completing the installation. The installation mechanism achieves quick connection without the need for bolts or welding. Installation can be achieved with simple operation.

[0023] Reference Figure 1-2 A slider 6 is threadedly connected to the trapezoidal threaded rod 8. The slider 6 is slidably connected to the left and right inner walls of the groove. A rectangular block 3 is fixedly connected to the left side of the slider 6.

[0024] During normal use, the device can be adjusted by starting the motor 9, which will drive the trapezoidal threaded rod 8 to rotate, causing the slider 6 connected to it to move the rectangular block 3, the camera 10 and the sensing component 12 up or down.

[0025] Reference Figure 1-3 The installation mechanism includes a limiting groove 15 opened in the rectangular block 3. A sliding plate 17 is slidably connected between the upper and lower inner walls of the limiting groove 15. The sliding plate 17 is elastically connected to the right inner wall of the limiting groove 15 through two compression springs 18.

[0026] Under the elastic action of the compression spring 18, the sliding plate 17 will exert a leftward force on the connecting block 5, which, in conjunction with the limiting action of the wedge block 16, makes the connecting block 5 more tightly limited. When disassembly is required, the pull plate 19 can be pulled upward, and the wedge block 16 will be moved upward through the pull rod 11, so that the wedge block 16 leaves the wedge groove 14. At this time, under the elastic action of the two compression springs 18, the sliding plate 17 will quickly move to the left, so that the two fixed structures can be quickly separated. This installation mechanism greatly simplifies the installation and disassembly process, reduces the difficulty of operation and safety hazards, improves work efficiency, and also improves the convenience and efficiency of maintenance.

[0027] Reference Figure 1-3 A wedge block 16 is horizontally arranged in the limiting groove 15. A pull rod 11 is fixedly connected to the upper end of the wedge block 16. The upper end of the pull rod 11 extends to the upper end of the rectangular block 3 and is fixedly connected to a pull plate 19. A pull ring is fixedly connected to the upper end of the pull plate 19. The lower end of the pull plate 19 is elastically connected to the upper end of the rectangular block 3 through two connecting springs 7. A connecting block 5 is arranged on one side of the rectangular block 3. A wedge groove 14 that cooperates with the wedge block 16 is opened at the upper end of the connecting block 5. A limiting block 13 that cooperates with the limiting groove 15 is fixedly connected to the left side of the connecting block 5. A mounting plate 4 is fixedly connected to the left side of the limiting block 13. A camera 10 is installed on the left side of the mounting plate 4. A sensing component 12 is arranged at the lower end of the mounting plate 4. The sensing component 12 includes methane, carbon monoxide, temperature and dust sensors.

[0028] The implementation principle of the mine underground safety monitoring device in this application embodiment is as follows: When the device is used, the fixing plate 1 is first installed on the inner wall of the mine by multiple bolts. Then, the connecting block 5 is inserted into the rectangular block 3. When the connecting block 5 passes the wedge block 16, it will push the wedge block 16 upward. When the wedge block 16 reaches the wedge groove 14, it will be inserted into the wedge groove 14 by the elastic action of the two connecting springs 7, thus completing the installation. The installation mechanism achieves quick connection without the need for bolts or welding. Installation can be achieved with simple operation.

[0029] During this process, the slide plate 17 will also be pushed to the right, causing the compression spring 18 to be in a compressed state. Under the elastic action of the compression spring 18, the slide plate 17 will give the connecting block 5 a force to the left, which, in conjunction with the limiting action of the wedge block 16, makes the connecting block 5 more tightly limited. When disassembly is required, the pull plate 19 can be pulled upward, and the wedge block 16 will be moved upward through the pull rod 11, causing the wedge block 16 to leave the wedge groove 14. At this time, under the elastic action of the two compression springs 18, the slide plate 17 will quickly move to the left, allowing the two fixed structures to separate quickly. This installation mechanism greatly simplifies the installation and disassembly process, reduces the difficulty of operation and safety hazards, improves work efficiency, and also improves the convenience and efficiency of maintenance.

[0030] During normal use, the device can be adjusted by starting the motor 9, which will drive the trapezoidal threaded rod 8 to rotate, causing the slider 6 connected to it to move the rectangular block 3, the camera 10 and the sensing component 12 up or down.
