Electronic sentry cameras are installed in high-traffic areas such as train stations to monitor the area and provide timely warnings of abnormal situations. Chinese Patent Publication No. CN221300843U discloses "An electronic sentry monitoring device, including a pole body, an electrical box body fixed to the surface of the pole body, and a sentry head body, further including: a lifting seat located on one side of the pole body for driving the raising and lowering of the sentry head body; two sets of connecting plates respectively bolted to the upper and lower sides of the pole body, with a first screw rotatably connected to the surface of the connecting plates; this utility model uses a rotating rod to drive the first screw to rotate, causing the threaded sleeve to drive the lifting seat and electronic..." The sentry head descends, allowing the electronic sentry head to a lower position for maintenance work. This is not only convenient but also safer for maintenance personnel working at a lower level. Simultaneously, after the electronic sentry head rises, rotating the second screw moves the locking plate, causing it to engage with the surface of the positioning post, thus locking the first screw and preventing the electronic sentry head from falling after reaching a high position. In existing technology, components such as a lifting platform are used to facilitate maintenance of the sentry head located at the top of the pole. However, while existing technology can achieve the purpose of raising and lowering the sentry head by setting up a lifting platform, it suffers from poor stability during the raising and lowering maintenance process and cannot effectively warn or isolate passing personnel, resulting in a lack of safety during maintenance.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1-6 This utility model discloses an electronic sentry device for personnel in train stations, comprising a pole 1 and an electronic sentry head 3. A support mechanism 2 is provided on the pole 1, the support mechanism 2 including a first support platform 4 and a second support platform 5. The electronic sentry head 3 is disposed on the first support platform 4. The first support platform 4 is slidably connected to the second support platform 5 through a support connector 6. The second support platform 5 is connected to a lifting assembly 7. The lifting assembly 7 is disposed in a slot 11 opened in the pole 1 for driving the second support platform 5 to move up and down along the height direction of the pole 1. A base 9 is fixed at the bottom of the pole 1, and a stabilizing isolation component 8 is provided between the base 9 and the second support platform 5.

[0029] The first support platform 4 has a first through hole through which the upright 1 passes. The first support platform 4 is slidably connected to the upright 1 through the first through hole. The first through hole makes the connection between the first support platform 4 and the upright 1 tighter and also improves the movement stability of the first support platform 4.

[0030] The supporting connector 6 includes two support rods 61 symmetrically arranged about the vertical center line of the upright 1. The top end of the support rod 61 is fixed to the first support platform 4, and the bottom end of the support rod 61 passes through a sliding hole 51 opened on the second support platform 5 and is slidably connected to the second support platform 5. The support rod 61 has a plurality of positioning holes 63, which are evenly distributed along the height direction of the support rod 61. The second support platform 5 is provided with a locking member, which extends into the sliding hole 51 and is threadedly connected to the positioning hole 63. The locking member includes a threaded rod, which is rotatably connected to the second support platform 5. After the threaded rod is rotated and loosened to disengage from the positioning hole 63, the support rod 61 can slide up and down in the sliding hole 51, thereby changing the distance between the first support platform 4 and the second support platform 5. When the position of the first support platform 4 is adjusted appropriately, the threaded rod is rotated in the opposite direction to make it threadedly connected to the corresponding positioning hole 63 in the sliding hole 51 to position the support rod 61.

[0031] The support connector 6 also includes several springs 62, which are arranged around the outside of the upright 1 and abut against the first support platform 4 and the second support platform 5. As the distance between the first support platform 4 and the second support platform 5 changes, the springs 62 also extend and retract. The arrangement of the springs 62 can buffer the movement of the first support platform 4 when the position of the first support platform 4 is adjusted, so as to prevent the first support platform 4 from falling too fast and affecting the operation safety.

[0032] A second through hole is provided at the center of the second support platform 5. The upright 1 passes through the second through hole. A slider 52 is fixed on the inner wall of the second through hole. The slider 52 passes through the slide groove 12 opened on the side wall of the upright 1 and extends into the empty groove 11 and is connected to the lifting assembly 7. The slide groove 12 is connected to the empty groove 11. The lifting assembly 7 drives the slider 52 to slide up and down in the slide groove 12, so that the height position of the second support platform 5 can be adjusted.

[0033] The lifting assembly 7 includes a lead screw 71 and a nut 72 threaded onto the lead screw 71. The nut 72 is fixedly connected to the slider 52. A motor 73 is provided at the bottom of the slot 11. The output end of the motor 73 is connected to the bottom end of the lead screw 71, and the top end of the lead screw 71 is rotatably connected to the top of the slot 11. When the motor 73 is running, the nut 72 moves up and down on the lead screw 71, thereby driving the slider 52 and the second support platform 5 to move up and down. The range of movement of the slider 52 in the slot 12 is consistent with the range of movement of the nut 72 on the lead screw 71.

[0034] At least four stabilizing isolation components 8 are provided, and the four stabilizing isolation components 8 are arranged at equal angles around the periphery of the upright 1 with the center of the upright 1 as the center. Each stabilizing isolation component 8 includes a first support rod 81 and a second support rod 82. The top end of the first support rod 81 is hinged to the second support platform 5, and the bottom end of the second support rod 82 is hinged to the top end of the second support rod 82. The bottom end of the second support rod 82 is hinged to the base 9. The second support rod 82 is provided with a protruding block. When the second support platform 5 is lowered to the lowest position, the first support rod 81 and the second support rod 82 are fully extended. At this time, the protruding block is on the same horizontal plane as the base 9, which can further play a supporting and stabilizing role, so that the stability of the support mechanism 2 is effectively improved. The extended support rods also increase the footprint, so that passers-by in the vicinity can clearly see that this place is in a state of not being approached and can stay away from this place to ensure safety.

[0035] The second support platform 5 is equipped with an electrical box body 10, which is electrically connected to the electronic sentry head 2. Placing the electrical box body 10 on the second support platform 5 can ensure that the electrical box body 10 is in a higher position and is better protected when the device is in normal use. When maintenance is required, the electrical box body 10 can also be lowered to facilitate maintenance operations.

[0036] The implementation principle of this utility model is as follows: When performing maintenance operations, after the motor 73 is turned on, the second support platform 5 and the first support platform 4 descend simultaneously, and the stabilizing isolation component 8 unfolds to support the ground. At this time, the second support platform 5 descends to its lowest position. The maintenance personnel can then adjust the support connecting component 6 according to the actual maintenance needs, so that the first support platform 4 can be further adjusted to a height that facilitates the maintenance personnel to maintain the electronic sentry head 3 on the first support platform 4.
