[0030] Embodiment 1: The present invention provides a video surveillance and alarm device for intelligent security, as shown in Figures 1-12As shown, it includes a camera housing 1. The lower end of the camera housing 1 abuts against an installation base 2. The bottom end of the camera housing 1 is fixedly connected with a trapezoidal protrusion 3. The outer surface of the bottom of the trapezoidal protrusion 3 is slidably connected with a lateral slider 4. Semi-circular grooves are formed on both lateral sliders 4. The semi-circular grooves on the lateral sliders 4 can form a complete circle, and the size of the circle matches the size of the threaded rotating member 10. The inner bottom end of the installation base 2 is fixedly connected with a reset spring rod 5. The other end of the reset spring rod 5 is fixedly connected with a limiting plate 6.

The outer surface of the U-shaped slider 8 is fixedly connected with a lateral spring rod 9. The other end of the lateral spring rod 9 is fixedly connected with the inner surface of the lateral slider 4. The telescopic spring rod 7 and the lateral spring rod 9 can ensure the stable movement track of the lateral slider 4, and at the same time offset a certain degree of vibration generated between the trapezoidal protrusion 3 and the lateral slider 4, ensuring the overall service life. The outer surface of the limiting plate 6 is slidably connected with the inner surface of the installation base 2. The outer surface of the U-shaped slider 8 is slidably connected with the inner surface of the trapezoidal protrusion 3, which can improve the stability of the movement of the limiting plate 6 and the U-shaped slider 8. The inner side of the camera housing 1 is threadedly connected with a threaded rotating member 10. The outer surface of the bottom of the threaded rotating member 10 is attached to the inner surface of the semi-circular groove on the lateral slider 4. By providing the trapezoidal protrusion 3 and the lateral slider 4, when the camera housing 1 and the installation base 2 are installed, the outer surface of the lateral slider 4 is attached and clamped with the inner surface of the installation base 2, completing the fixation between the camera housing 1 and the installation base 2, and the lateral slider 4 is self-locked by the reset spring rod 5 and the limiting plate 6 to ensure that separation does not occur during use, facilitating the quick installation of the camera housing 1 and the installation base 2. When replacing, twist the threaded rotating member 10. The threaded rotating member 10 pushes the limiting plate 6 back into the installation base 2 to release the limit on the lateral slider 4. The lateral slider 4 is driven by the telescopic spring rod 7 and the lateral spring rod 9 to be attached to the outer surface of the threaded rotating member 10, releasing the fixation between the camera housing 1 and the installation base 2, facilitating the quick replacement and repair of the camera housing 1.

[0031] As Figures 1-12As shown, a Y-shaped slider 11 is slidably connected to the inner surface of the camera housing 1.

The outer surface of the guide rod 17 is slidably connected to the inner surfaces of the remaining Y-shaped sliders 11. A fixed bracket 18 is fixedly connected to the bottom end of the clamping plate 14 near the threaded lead screw 16. A second shock absorber 19 is fixedly connected to the outer surface of the bottom end of the fixed bracket 18. The other end of the second shock absorber 19 is fixedly connected to a mounting bracket 20. A driving motor 21 is fixedly connected to the bottom end of the mounting bracket 20. The output end of the driving motor 21 is fixedly connected to a driving roller 22. The outer surface of the bottom end of the driving roller 22 is rotatably connected to the inner surface of the mounting bracket 20. A protective cover 23 is rotatably connected to the inner surface of the camera housing 1. An annular gear is provided inside the protective cover 23. The annular gear is in contact with the outer surface of the clamping plate 14. The outer surface of the driving roller 22 is slidably connected to the inner surface of the protective cover 23. By providing the Y-shaped slider 11 and the spring connecting rod 12, the movement of the clamping plate 14 can be ensured to be synchronous, ensuring the reliability of the limit on the protective cover 23. And the first shock absorber 13 and the second shock absorber 19 are provided to ensure the reduction of vibration generated during use and improve the service life. Through the driving motor 21 and the driving roller 22, when the surface of the protective cover 23 is contaminated, the protective cover 23 can be rotationally adjusted to avoid the lack of the monitoring screen and improve the overall practicality and reliability.

[0032] As Figures 1-12As shown in the figure, a square hole is provided on the Y-shaped slider 11 close to the threaded lead screw 16. The inner surface of the square hole is slidably connected to the outer surface of the fixed frame 18. The middle of the bottom end of the camera housing 1 is fixedly connected with a mounting plate 24. The top and bottom ends of the mounting plate 24 are fixedly connected with a first adjustment motor 25. The output end of the first adjustment motor 25 is fixedly connected with a rotating frame 26. The outer surface of the bottom end of the rotating frame 26 is rotatably connected to the inner surface of the mounting plate 24. The outer surface of the upper part of the rotating frame 26 is fixedly connected with a second adjustment motor 27. The output end of the second adjustment motor 27 is fixedly connected with a monitoring camera 28. The outer surfaces of both ends of the monitoring camera 28 are rotatably connected to the inner surface of the upper part of the rotating frame 26. By means of the first adjustment motor 25 and the second adjustment motor 27, the monitoring direction of the monitoring camera 28 can be controlled, which is convenient for monitoring different positions. The outer surface of the camera housing 1 is wired to a monitoring host 29. The auxiliary motor 15, the driving motor 21, the first adjustment motor 25 and the second adjustment motor 27 are electrically connected to the monitoring host 29. The output end of the monitoring host 29 is electrically connected to an external alarm, which is convenient for warning security personnel and ordinary personnel.

[0033] Working principle: During installation, install the mounting base 2 on the surface to be fixed. Align the trapezoidal protrusion 3 with the opening on the mounting base 2. After alignment, insert it. The sliding connection between the trapezoidal protrusion 3 and the lateral slider 4 drives the lateral slider 4 to move to both sides until the lateral slider 4 is fully clamped and fitted with the inner surface of the mounting base 2. Then, the reset spring rod 5 drives the limiting plate 6 to limit the lateral slider 4, completing the installation and fixation of the camera housing 1 and the mounting base 2, ensuring that they will not separate during use, facilitating the quick installation of the camera housing 1 and the mounting base 2. During replacement, twist the threaded rotating part 10. The threaded rotating part 10 pushes the limiting plate 6 back into the mounting base 2, releasing the limit on the lateral slider 4. The lateral slider 4 fits with the outer surface of the threaded rotating part 10 under the drive of the telescopic spring rod 7 and the lateral spring rod 9, releasing the fixation between the camera housing 1 and the mounting base 2, facilitating the quick replacement and repair of the camera housing 1. Push the protective cover 23 into the camera housing 1. Through the abutting and sliding of the annular teeth on the protective cover 23 and the clamping plate 14, drive the clamping plate 14 to move inward, thus completing the installation. At the same time, after the installation is in place, the first shock absorber 13 and the second shock absorber 19 respectively drive the clamping plate 14 and the driving roller 22 to pre-limit the protective cover 23. After that, start the driving motor 21. The output end of the driving motor 21 drives the Y-shaped slider 11 to move towards the clamping plate 14, thereby increasing the tension of the first shock absorber 13 and the second shock absorber 19, improving the limiting and protective effect on the protective cover 23 and avoiding the situation of falling off. Inside the camera housing 1, there are a Y-shaped slider 11 and a spring connecting rod 12, which can ensure the synchronous movement of the clamping plate 14 and ensure the reliability of the limit on the protective cover 23. And the first shock absorber 13 and the second shock absorber 19 are provided to ensure the reduction of vibration generated during use and improve the service life. Through the driving motor 21 and the driving roller 22, when the surface of the protective cover 23 is contaminated, the protective cover 23 can be rotationally adjusted to avoid the lack of monitoring pictures. At the same time, the information is sent into the monitoring host 29, facilitating the notification of personnel for maintenance and replacement, avoiding the situation of lack of monitoring during the period to be replaced, and improving the overall practicality and reliability. By adjusting the first motor 25 and the second motor 27, the left-right and up-down monitoring directions of the monitoring camera 28 can be controlled respectively. At the same time, the monitoring pictures are sent into the monitoring host 29, facilitating the monitoring and recording of different positions. It can cooperate with the driving roller 22 to ensure that the monitoring will not fail due to local contamination, improving the overall functionality and practicality.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
