Abstract
Description
Technical Field
[0001] This utility model relates to the field of video surveillance technology, and in particular to an alarm status video surveillance device. Background Technology
[0002] Alarm-activated video surveillance devices are video surveillance equipment that automatically activates or switches to a specific monitoring mode when an alarm is triggered. These devices are commonly used in security monitoring systems. When an anomaly is detected (such as intrusion, fire, smoke, etc.), the alarm state is activated, and the monitoring device automatically records video, switches feeds, or sends an alarm signal to the monitoring center for timely response. These devices are commonly found in shopping malls, factories, schools, and other similar locations to enhance security and rapid response capabilities.
[0003] Existing alarm-state video surveillance devices are usually installed at high places. When the equipment malfunctions and needs to be repaired or routinely maintained, staff often need to use ladders or other climbing tools to operate it, which poses certain safety hazards. Moreover, ordinary video surveillance cameras, due to their limited field of view and distance, can only cover a certain area and cannot effectively detect areas outside the field of view. This limitation may lead to the emergence of monitoring blind spots. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an alarm status video monitoring device. Through the linkage design of multiple lifting boxes, the monitoring device can achieve flexible lifting function, making inspection or maintenance more convenient.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Referring to Figures 1, 3, and 4, one embodiment of this utility model provides an alarm status video monitoring device, including a fixed box 1. A fixed column 7 is fixedly connected to the outer wall of the fixed box 1. A cylinder 18 is fixedly connected to the top of the inner wall of the fixed box 1. A U-shaped plate 17 is fixedly connected to the driving end of the cylinder 18. A first lifting box 2 is fixedly connected to the lower end of the U-shaped plate 17. A first rack 15 is fixedly connected to the right side of the inner wall of the fixed box 1. The first rack 15 is meshed with a first gear 14. A second rack 16 is meshed with the left end of the first gear 14. A first limiting groove is opened in the inner wall of the first lifting box 2. The first gear 14 is rotatably connected to the inner wall of the first limiting groove. A second lifting box 3 is fixedly connected to the left end of the second rack 16. A second limiting groove is opened in the inner wall of the second lifting box 3. A second gear 19 is rotatably connected to the inner wall of the second limiting groove. A third rack 20 is meshed with the right end of the second gear 19. The third rack 20 is fixedly connected to the first lifting box 2. On the inner wall, the left end of the second gear 19 is meshed with the fourth rack 21, and the left end of the fourth rack 21 is fixedly connected to the third lifting box 4.
[0024] Specifically, the fixed column 7 is used to install the monitoring device on the wall. When the cylinder 18 is activated, the driving end of the cylinder 18 pushes the U-shaped plate 17 downward. The U-shaped plate 17 drives the first lifting box 2 downward, that is, the first gear 14 moves downward. The first gear 14 rotates under the meshing connection of the first rack 15. The first gear 14 pushes the second rack 16 downward, that is, the second lifting box 3 moves downward. The second lifting box 3 drives the second gear 19 downward. The second gear 19 rotates under the meshing connection of the third rack 20. The second gear 19 pushes the fourth rack 21 downward, that is, the third lifting box 4 moves downward. This setting can move the camera 6 downward, so that maintenance of the camera 6 no longer requires climbing ladders or other high-altitude equipment.
[0025] Referring to Figures 1 and 2, a control box 5 is fixedly connected to the bottom of the third lifting box 4. A motor 12 is fixedly connected to the inner wall of the control box 5. A bevel gear 11 is fixedly connected to the drive end of the motor 12. A first bevel gear 9 is meshed with the top of the bevel gear 11. A rotating rod 8 is fixedly connected to the inner wall of the first bevel gear 9. A second bevel gear 10 is meshed with the bottom of the bevel gear 11. The second bevel gear 10 is fixedly connected to the outer wall of the rotating rod 8. A camera 6 is fixedly connected to the bottom of the rotating rod 8. The camera 6 is located at the lower end of the control box 5. The rotating rod 8 and the control box 5 are rotatably connected. An alarm 13 is fixedly connected to the inner wall of the control box 5.
[0026] Specifically, the motor 12 inside the control box 5 is turned on, and the motor 12 drives the bevel gear 11 to rotate. When the teeth of the bevel gear 11 mesh with the first bevel gear 9, the first bevel gear 9 is driven to rotate, and the rotating rod 8 rotates accordingly. When the teeth of the bevel gear 11 mesh with the second bevel gear 10, the second bevel gear 10 is driven to rotate in the opposite direction, and the rotating shaft rotates in the opposite direction, thereby realizing the reciprocating swing of the camera 6, making the shooting angle of the camera 6 wider. When an abnormal situation occurs, the alarm 13 sounds and automatically activates the background video monitoring system.
[0027] Working principle: When using this device, the motor 12 inside the control box 5 is turned on. The motor 12 drives the bevel gear 11 to rotate. When the teeth of the bevel gear 11 mesh with the first bevel gear 9, it drives the first bevel gear 9 to rotate, and the rotating rod 8 rotates accordingly. When the teeth of the bevel gear 11 mesh with the second bevel gear 10, it drives the second bevel gear 10 to rotate in the opposite direction, and the rotating shaft rotates in the opposite direction, thereby realizing the reciprocating swing of the camera 6, making the shooting angle of the camera 6 wider. The fixing column 7 is used to install the monitoring device on the wall. When the cylinder 18 is turned on, the driving end of the cylinder 18 pushes the U-shaped plate 17 to move downward. The U-shaped plate 17 drives the first lifting box 2 to move downward, that is, the first gear 14 moves downward. The first gear 14 rotates under the meshing connection of the first rack 15. The first gear 14 pushes the second rack 16 to move downward, that is, the second lifting box 3 moves downward. The second lifting box 3 drives the second gear 19 to move downward. Rotating under the meshing action of the third rack 20, the second gear 19 pushes the fourth rack 21 to move downward, that is, the third lifting box 4 moves downward. This setting can move the camera 6 downward, so that maintenance of the camera 6 no longer requires climbing equipment such as ladders.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
