[0021] Please see Figure 1-4 This utility model provides a technical solution: a security monitoring device for smart cities, comprising:

[0022] A bottom mounting base 1 is provided, and a support box 2 is fixedly welded to the top wall of the bottom mounting base 1. A servo motor 3 is fixedly installed in the inner cavity of the support box 2. The output end of the servo motor 3 is connected to a screw 4. Two guide rods 5 are fixedly welded to the top wall of the support box 2. The two guide rods 5 are symmetrically arranged on both sides of the screw 4. A first support cylinder 6 is fixedly installed on the top wall of the support box 2. A second support cylinder 7 is provided on the first support cylinder 6. A third support cylinder 8 is provided on the second support cylinder 7. The first support cylinder 6, the second support cylinder 7 and the third support cylinder 8 are all sleeved on the screw 4 and the guide rods 5. A mounting frame 9 is fixedly installed on the third support cylinder 8. A monitoring camera 10 is installed on the mounting frame 9. The monitoring camera 10 is existing publicly available technology, and its working principle and specific structure will not be described in detail. A movable seat 11 is threadedly connected to the screw 4. The movable seat 11 is slidably connected to the two guide rods 5 through an opening.

[0023] The top ends of the first support cylinder 6 and the second support cylinder 7 are both fixedly welded with annular baffles 12, and the bottom ends of the second support cylinder 7 and the third support cylinder 8 are both fixedly welded with annular connecting seats 13. The second support cylinder 7 and the third support cylinder 8 are slidably connected in the two annular baffles 12 respectively. The top end of the third support cylinder 8 is fixedly welded with a top plate 14. The top ends of the screw 4 and the guide rod 5 pass through the top plate 14. The second support cylinder 7 can slide and extend in the first support cylinder 8, and the third support cylinder 8 can slide and extend in the second support cylinder 7, thereby adjusting the height of the monitoring camera 10.

[0024] An annular sealing gasket 15 is fixedly installed on the top wall of both annular connecting seats 13. Multiple mounting holes 16 are provided on the bottom mounting seat 1. The annular sealing gasket 15 can improve the connection sealing when the annular connecting seat 13 is connected to the annular baffle 12 to prevent rainwater from entering. The mounting holes 16 can be fixed to the bottom mounting seat 1 by the provided ground nails.

[0025] An operation box 17 is fixedly installed on the first support cylinder 6. A control switch 18 is fixedly installed inside the operation box 17. A box door 19 with a mechanical lock is installed on the operation box 17.

[0026] The control switch 18 is electrically connected to the servo motor 3 via a wire, and the control switch 18 is used to control the operation of the servo motor 3.

[0027] A rain cover 20 is provided above the third support cylinder 8. The rain cover 20 is fixedly installed on the top of the two guide rods 5. The rain cover 20 can protect the monitoring camera 10 from rain and snow.

[0028] Working Principle: This utility model, through the arrangement of a first support cylinder 6, a second support cylinder 7 that can slide and extend on the first support cylinder 6, and a third support cylinder 8 that can slide and extend on the second support cylinder 7, allows the servo motor 3 to be controlled by the control switch 18 when the monitoring camera 10 needs to be raised or lowered. This drives the screw 4 to rotate, causing the moving seat 11 to rise and fall on the screw 4, thereby driving the extension and retraction of the second support cylinder 7 and the third support cylinder 8. Furthermore, the screw 4 is housed within the inner cavities of the first support cylinder 6, the second support cylinder 7, and the third support cylinder 8, preventing it from being corroded by rainwater during daily use, thus extending its service life and reducing [damage / loss]. The frequency of maintenance and replacement, and the specific operating procedures are as follows: When it is necessary to lower the monitoring camera 10, simply make the servo motor 3 drive the screw 4 to rotate in the opposite direction, so that the moving seat 11 moves downward. During the downward movement of the moving seat 11, the third support cylinder 8 slides down and retracts in the second support cylinder 7 under the action of its own weight and the weight of the monitoring camera 10. Simply make the mounting bracket 9 lock at the top of the second support cylinder 7, and then the second support cylinder 7 begins to slide down and retract until the monitoring camera 10 moves down to the top of the first support cylinder 6, so that the monitoring camera 10 can be lowered for easy inspection and maintenance. When raising, simply make the screw 4 rotate in the forward direction.
