Description

Technical Field

[0001] The invention relates to the technical field of disaster monitoring, in particular to a landslide disaster monitoring device for a mine rock and soil slope. Background Art

[0002] Landslides and mud-rock flows have caused irreparable losses to the people. At present, in order to prevent such natural disasters, various places have gradually established a mass prevention and monitoring system, carried out regular inspections, checked potential disaster sites, and conducted key monitoring of major potential disaster sites. However, these measures are still mainly completed manually, and the monitoring technologies that have been used are relatively backward.

[0003] For example, the document with announcement number CN215984599U discloses a portable dynamic monitoring device for landslides and mud-rock flow disasters. When the portable dynamic monitoring device for landslides and mud-rock flow disasters needs to be transported, one person lifts the base body and starts the motor to drive the inclined gear to rotate and drive the threaded rod to rotate synchronously, so that the movable plate sleeved on the upper end of the threaded rod is lifted up and down, and when the movable plate moves downward, it drives the universal wheel to fall through the square groove opened at the bottom of the base body. When the upper end of the universal wheel is closed with the square groove, the motor is turned off, and the base body is pushed to make the universal wheel slide on the ground to move, which saves the workers' physical strength and improves the transportation efficiency. Through this portable method, the problem that the overall equipment can only be carried by workers and is not convenient to carry is solved.

[0004] For example, the document with publication number CN203811203U discloses a rainfall-induced landslide disaster monitoring system. By real-time monitoring of the landslide surface displacement, rainfall intensity and water content at different depths of the landslide, it can comprehensively and objectively evaluate the critical rainfall threshold and evolution process of the landslide, providing reliable data and scientific basis for early warning and prevention of landslides. At the same time, the utility model is simple to operate, low-cost and easy to promote.

[0005] However, in the daily application of monitoring equipment, due to the need to monitor a wide area, it is often necessary to add multiple monitoring cameras, which invisibly increases the cost of use. Although a mobile mechanism can be added to adjust the position of the monitoring camera, the long length of the guide rail makes it easy for the guide rail to collide with tree branches or other obstacles when the landslide disaster monitoring equipment is moved, causing damage to the monitoring camera. In addition, the monitoring camera lacks protection when not in use, which is not conducive to mobile transportation. Summary of the invention

[0040] Example 2: Please refer to Figure 7-Figure 9A landslide disaster monitoring device for rock and soil slopes in mines, wherein the protection and cleaning mechanism 74 comprises a support seat 741, a protection frame 742, a receiving seat 1 743, a receiving seat 2 744, a support rod 1 745, a triangular scraper 746, a support rod 2 747, and an elastic pull rope 748. The support seat 741 is fixed to the front end of the fixing block 72, and the support seat 741 and the protection frame 742 are an integrated structure. The front ends of the receiving seat 1 743 and the receiving seat 2 744 are both bolted to the protection frame 742, and one end of the support rod 1 745 is connected to the receiving seat 2 746. 44, and the other end of the support rod 1 745 is bolted to the triangular scraper 746, one end of the support rod 2 747 is bolted to the rear end of the receiving seat 1 743, and the other end of the support rod 2 747 is bolted to the triangular scraper 746, the support seat 741 and the protective frame 742 form a U-shaped structure with each other, and the length of the top cross plate of the protective frame 742 is less than the length of the support seat 741, and the cross section of the triangular scraper 746 is a triangular structure. This structure can not only scrape off all the dust, but also make the scraped dust Dust flows back along the inclination of the triangular scraper 746 to prevent dust from adhering to the lens again. The receiving seat 1 743 and the receiving seat 2 744 are arranged in parallel with each other. There are two groups of support rods 1 745, and the support rods 1 745 and the support rods 2 747 are arranged in an inclined shape. Hanging rings are arranged on the receiving seat 1 743 and the triangular scraper 746, and the elastic pull rope 748 passes through the hanging ring to connect the receiving seat 1 743 and the triangular scraper 746 in series, so that the receiving seat 1 743 and the triangular scraper 746 are flexibly connected in series, so that The triangular scraper 746 can fit tightly with the front end lens of the dynamic monitoring camera 737 to remove dust from the lens of the dynamic monitoring camera 737. When the dynamic monitoring camera 737 is not in use or needs to be transported, the fixed plate 736 on the dynamic monitoring camera 737 is adjusted to a state where it is vertically arranged with the slider 735. The dynamic monitoring camera 737 can be recovered to the inside of the protective frame 742 through the telescopic moving mechanism 73 for protection to prevent the dynamic monitoring camera 737 from being damaged during movement and transportation.

[0041] In summary, when in use, the landslide disaster monitoring device is moved to a suitable position on the rock and soil slope of the mine, and when moving, the round rod 75 is set to be parallel to the vertical rod 5. At this time, the dynamic monitoring camera 737 is located in the protective frame 742, which can effectively reduce the overall volume of the landslide disaster monitoring device and prevent the round rod 75 from colliding with branches or other obstacles.

[0042] After moving to the appropriate position, first pull the pull rod 714 to the right end, and the pull rod 714 drives the push rod 716 to move to the right end. After releasing the support limit of the block 717, the fixed block 72 is then rotated counterclockwise to make the fixed block 72 drive the block 717 to rotate ninety degrees in the circular groove 718 through the rotating shaft 719. Then, the pulling force on the pull rod 714 is released, and the elastic potential energy of the deformation is restored by the compression spring 7110, driving the push rod 716 to move to the left end of the slide groove 715, thereby blocking the bottom of the circular groove 718, and supporting the bottom horizontal surface of the block 717 to limit the block 717. Figure 4 As shown, at this time, the block 717 cannot rotate due to the limit of the top rod 716, and at the same time, the round rod 75 is set horizontally, so that the horizontal or vertical state of the round rod 75 can be adjusted, making the landslide disaster monitoring equipment easy to move and transport;

[0043] Then the electric push rod 732 is extended to push the connecting rod 733, so that the connecting rod 733 moves on the movable seat 2 734, and the electric push rod 732 moves accordingly on the movable seat 1 731, so that the slider 735 moves horizontally on the round rod 75, and the horizontal position of the dynamic monitoring camera 737 on the round rod 75 is adjusted. Two groups of dynamic monitoring cameras 737 are provided, and their respective horizontal positions on the round rod 75 can be adjusted according to actual use, so as to increase the monitoring range of the rock and soil slope of the mine. The data monitored by the dynamic monitoring camera 737 is processed by the controller 4 and transmitted to the remote data receiving center through the wireless receiver for real-time monitoring.

[0044] Similarly, when the dynamic monitoring camera 737 needs to be protected, the electric push rod 732 can be retracted to move the dynamic monitoring camera 737 toward the inside of the protection frame 742. When the dynamic monitoring camera 737 moves, the tip of the triangular scraper 746 first contacts the lens of the dynamic monitoring camera 737. As the dynamic monitoring camera 737 moves toward the inside of the triangular scraper 746, the contact surface between the triangular scraper 746 and the lens of the dynamic monitoring camera 737 gradually extends to the upper and lower sides, so as to scrape off the dust on the surface of the lens of the dynamic monitoring camera 737, thereby increasing the service life of the dynamic monitoring camera 737 and increasing the monitoring accuracy of the dynamic monitoring camera 737.

[0045] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.

The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field.
