[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-5 As shown, this utility model provides a video surveillance emergency alarm device, including a horizontal frame 1. Mounting brackets 2 are symmetrically fixed on both sides of the upper end of the horizontal frame 1. A mounting plate 3 is provided on the lower side of the horizontal frame 1. A lifting mechanism 4 is connected to the lower end of the mounting plate 3. An adjustment component 5 is installed on the lower side of the lifting mechanism 4. An audible and visual alarm 6 is provided on the front side of the adjustment component 5. A bracket 7 is movably installed on the lower side of the adjustment component 5. A camera 8 is fixedly mounted on the top of the bracket 7. Disassembly and assembly mechanisms 9 are provided on both sides of the upper end of the bracket 7. A lead screw 10 is rotatably mounted inside the horizontal frame 1. A threaded seat 11 is threaded onto the outside of the lead screw 10. Slider blocks 12 are fixed on both sides of the threaded seat 11. Slide grooves 13 are opened on the front and rear inner walls of the horizontal frame 1. A motor 14 is fixedly mounted on one end of the horizontal frame 1.

[0025] The upper end of the mounting plate 3 is fixedly connected to the lower end of the threaded seat 11, and the bottom end of the audible and visual alarm 6 is fixedly connected to the front side of the bottom frame 51.

[0026] The top end of the lead screw 10 is driven and installed at the output end of the motor 14, and the slider 12 is fitted into the slide groove 13 and is movably installed.

[0027] In this solution, when the threaded seat 11 moves horizontally left and right, it can drive the slider 12 to slide synchronously in the slide groove 13, thereby limiting its movement and preventing it from rotating. The camera 8 can capture video and transmit the video to the controller, which then transmits it to the external display screen for staff to view the video content. In case of any abnormal situation, the controller can be used to activate the audible and visual alarm 6 to send an alarm signal to the surrounding crowd.

[0028] like Figure 3As shown, the lifting mechanism 4 includes a mounting frame 41. The upper side of the mounting frame 41 is fixedly connected to the lower end of the mounting plate 3. A side frame 42 is fixedly installed inside the lower end of the mounting frame 41. A winding roller 43 is rotatably installed inside the side frame 42. A wire rope 44 is wound around the outside of the winding roller 43. A motor 45 is fixedly installed at one end of the side frame 42. Multi-stage telescopic rods 46 are symmetrically fixed on both sides of the lower end of the mounting plate 3. Ear plates 47 are fixedly installed at the lower end of the multi-stage telescopic rods 46.

[0029] The output end of motor 45 is driven and installed at the top of take-up roller 43, and wire rope 44 can extend through the inside of mounting frame 41.

[0030] In this solution, when the steel wire rope 44 drives the bottom frame 51 to descend, the bottom frame 51 can use the ear plate 47 to drive the multi-stage telescopic rod 46 to move synchronously, thereby improving the stability of the movement of the bottom frame 51 and other components. The lifting structure eliminates the need for manual climbing to high places for operation, fundamentally avoiding the dangers of falling that may be caused by manual climbing, and greatly improving the safety of maintenance work.

[0031] like Figure 4 As shown, the adjustment component 5 includes a base frame 51, the upper end of which is fixedly connected to the lower end of the wire rope 44. A rotating shaft 52 is rotatably mounted in the middle of the base frame 51. A gear 53 is fixedly sleeved on the lower side of the rotating shaft 52. A fixing plate 54 is fixedly provided at the lower end of the rotating shaft 52. A ring block 55 is fixedly provided on the inner wall of the upper end of the base frame 51. A retaining ring 56 is fixedly sleeved on the upper end of the rotating shaft 52. A motor 57 is fixedly provided on one side of the lower end of the base frame 51. A gear 58 is drivenly connected to the top of the output rod of the motor 57.

[0032] The lower end of the rotating shaft 52 extends through the interior of the base frame 51. The retaining ring 56 is engaged with the annular groove opened inside the ring block 55 and is rotatably connected. The second gear 58 meshes with the first gear 53. The upper two sides of the base frame 51 are fixedly connected to one end of the ear plate 47.

[0033] In this design, the rotating shaft 52 can drive the retaining ring 56 to rotate in the inner groove of the ring block 55 when it rotates, thereby limiting the rotation of the rotating shaft 52 and improving its rotational stability.

[0034] like Figure 5As shown, the disassembly and assembly mechanism 9 includes a positioning frame 91. The upper side of the positioning frame 91 is fixedly connected to the front and rear sides of the lower end of the fixing plate 54. The upper sides of the bracket 7 are symmetrically fixed with insert plates 92. The insert plates 92 have an insertion hole 93 in the middle. The lower left and right sides of the fixing plate 54 are fixedly connected with side frames 94. The middle of the inside of the side frames 94 is fixedly provided with a base 95. The sides of the base 95 are fixedly provided with slide rods 96. The outside of the slide rods 96 is sleeved with a spring 97. The front side of the slide rods 96 is slidably sleeved with a sleeve 98. The front end of the sleeve 98 is fixedly provided with a force plate 99. The top of the sleeve 98 is fixedly provided with a plug 910.

[0035] The positioning frame 91 is arranged in a "U-shape". The two ends of the spring 97 are fixedly connected to the opposite surfaces of the fixed base 95 and the sleeve 98 respectively. The sleeve 98 can slide out of the interior of the side frame 94. The plug 910 is movably installed inside the socket 93. The front surface of the side frame 94 is provided with a guide groove. The force plate 99 is slidably connected to the interior of the guide groove.

[0036] In this solution, the bracket 7 can be placed inside the positioning frame 91 on the fixed plate 54, so that the positioning frame 91 can quickly limit the top of the bracket 7. Then the force plate 99 can be released, so that the compressed spring 97 can rebound, thereby pushing the sleeves 98 on both sides of the slide rod 96 to gradually move away, so that the sleeves 98 can push the plug 910 directly into the socket 93 on the plug plate 92, thereby limiting the bracket 7 and completing the installation of the camera 8.

[0037] The working principle of this video surveillance emergency alarm device will be explained in detail below.

[0038] like Figures 1-5As shown, when using this video surveillance emergency alarm device, the horizontal frame 1 can be fixed in a suitable position using the mounting bracket 2, facilitating normal operation. When it is necessary to adjust the monitoring range of the camera 8, motor 14 can be started first. Motor 14 drives the lead screw 10 to rotate, which in turn drives the threaded seat 11 to move horizontally left and right. This causes the threaded seat 11 to drive the mounting frame 41, bottom frame 51, bracket 7, and camera 8 to move synchronously via the mounting plate 3, facilitating adjustment of the device's position. At this time, motor 3 57 can also be turned on, which drives gear 2 58 to rotate. The rotating gear 2 58, through the meshing gear 1 53, drives the rotating shaft 52 to rotate. The rotating shaft 52, through the fixing plate 54, drives the bracket 7 and camera 8 to rotate at an angle, thereby adjusting the monitoring position of the device and improving its performance. The monitoring range is expanded, allowing the equipment to be positioned at the optimal monitoring angle, thus greatly improving the equipment's flexibility. When maintenance is required, motor 2 45 can be turned on, causing the take-up roller 43 to rotate in the opposite direction. This loosens the steel wire rope 44 wound on the take-up roller 43, allowing the base frame 51, bracket 7, and camera 8 to gradually descend, enabling maintenance to be carried out in a suitable position without the need for manual climbing to a high place, thus avoiding danger. At the same time, by pulling the force plates 99 on the side frames 94 at the lower end of the fixing plate 54, the force plates 99 drive the sleeves 98 on both sides to gradually approach each other on the slide rod 96, thereby compressing the spring 97. This also separates the plug 910 on the sleeve 98 from the socket 93 on the plug plate 92, facilitating the quick disassembly of the bracket 7 and the removal of the camera 8 for convenient maintenance.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
