Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal bunker monitoring technology, and in particular to a coal bunker video monitoring device. Background Technology
[0002] In most coal mines, centralized ground-based monitoring and recording of coal bunkers has been implemented. The monitoring devices utilize fiber optics, coaxial cables, or microwaves to transmit video signals within a closed loop, forming an independent and complete system from camera capture to image display and recording. It can reflect the monitored object in real time, vividly, and realistically, greatly extending the observation distance of the human eye and expanding its capabilities. It can replace manual monitoring for extended periods in harsh environments, allowing people to see everything actually happening at the monitored site and record it via video recorder.
[0003] The existing coal bunker monitoring device includes a mounting plate with a support rod vertically fixed outward from the center of the mounting plate. A connecting rod is vertically connected downward from the other end of the support rod, and a monitoring device is fixedly connected to the bottom of the connecting rod. The monitoring device includes a horizontally mounted mounting plate with a mounting base at the center of the bottom of the mounting plate. A camera is mounted below the mounting base. A mounting cover is located outside the camera below the mounting plate. A housing is located above the mounting plate, and a cleaning device is movably mounted on the outer wall of the mounting cover. The cleaning device includes connecting plates vertically fixed downward at both ends of the bottom of the mounting plate. A rotating shaft is horizontally connected inward to the inner side of each connecting plate via bearings. A movable plate is connected via bearings at the other end of the rotating shaft. A sponge layer is fixedly connected to the movable plate near the side of the mounting cover. However, the existing monitoring equipment has a relatively fixed operating range, thus limiting the monitoring area and preventing the monitoring of obstructions and elevation angles within the monitored area. Utility Model Content
[0004] In order to overcome the limitation of the monitoring range in the existing technology, this utility model provides a coal bunker video monitoring device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a coal bunker video monitoring device, including a top plate and a monitoring camera. An electric telescopic rod is provided at the lower part of the top plate. A support plate is provided at the output end of the electric telescopic rod. A connecting rod is fixed at one end of the support plate. A telescopic cylinder is hinged to the other end of the support plate. The monitoring camera is installed on a movable frame. A connecting rod is hinged to one end of the movable frame. The output end of the telescopic cylinder is hinged to the other end of the movable frame.
[0006] As a further improvement of this utility model, screws are provided on the top plate.
[0007] As a further improvement of this utility model, the support plate is an arc-shaped cover plate.
[0008] As a further improvement of this utility model, the output end of the electric telescopic rod is connected to the support plate via a servo motor.
[0009] As a further improvement of this utility model, a groove is provided in the middle of the movable frame, and the monitoring camera can be detachably installed in the groove.
[0010] As a further improvement of this utility model, a surface-facing device is provided on the top of the lower side of the support plate.
[0011] Compared with the prior art, the present invention has the following advantages: In this solution, the electric telescopic pole adjusts the monitoring height. It can be adjusted vertically according to the required monitoring range and area, reducing the obstruction of some equipment and thus increasing the monitoring range of the monitoring camera. On the other hand, by extending and retracting the telescopic cylinder, the monitoring camera can be rotated, which can adjust the monitoring camera to a suitable angle and increase the monitoring range of the monitoring camera, thereby expanding the monitoring range of the coal bunker. Attached Figure Description
[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0013] Figure 1 This is a schematic diagram of the structure of a video monitoring device for a coal bunker according to the present invention.
[0014] In the diagram: 1. Top plate; 2. Screw; 3. Electric telescopic rod; 4. Servo motor; 5. Support plate; 6. Telescopic cylinder; 7. Connecting rod; 8. Movable frame; 9. Monitoring camera; 10. Illumination equipment. Detailed Implementation
[0015] To make the technical solution and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0016] Reference Figure 1 This utility model discloses a video monitoring device for a coal bunker, including a top plate 1 and a monitoring camera 9. The lower part of the top plate 1 is provided with an electric telescopic rod 3, and the output end of the electric telescopic rod 3 is provided with a support plate 5. One end of the support plate 5 is fixed with a connecting rod 7, and the other end of the support plate 5 is hinged with a telescopic cylinder 6. The monitoring camera 9 is mounted on a movable frame 8, one end of the movable frame 8 is hinged with the connecting rod 7, and the other end of the movable frame 8 is hinged with the output end of the telescopic cylinder 6.
[0017] The top plate 1 is equipped with screws 2, which are used to fix the top plate 1 to the top of the warehouse.
[0018] In use, the surveillance camera 9 is an existing monitoring device capable of multi-angle rotation monitoring. The movable frame 8 has a groove in the middle, allowing the surveillance camera 9 to be detachably installed within the groove for easy disassembly and installation. The electric telescopic pole 3 adjusts the monitoring height, allowing for vertical adjustment based on the required monitoring range and area, reducing obstruction by some equipment and thus increasing the monitoring range of the surveillance camera 9. Furthermore, the telescopic cylinder 6 extends and retracts, causing the surveillance camera 9 to rotate, allowing it to be adjusted to a suitable angle and further increasing its monitoring range.
[0019] The support plate 5 is an arc-shaped cover that protects the monitoring camera 9 from damage. A lighting device 10 is installed on the top of the lower side of the support plate 5. The lighting device 10 illuminates the coal bunker, making the monitoring image clearer and improving the monitoring effect.
[0020] The output end of the electric telescopic pole 3 is connected to the support plate 5 via a servo motor 4. The servo motor 4 drives the support plate 5 to rotate as a whole, which in turn drives the monitoring camera 9 to rotate, enabling the monitoring camera 9 to rotate 360 degrees in the horizontal plane, providing a wider range of adjustment and thus making the monitoring more accurate.
[0021] It should be understood that the specific embodiments described herein are for understanding the present invention only and are not intended to limit the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
