Description

Technical Field

[0001] This utility model relates to the field of electronic sentinel technology, specifically to an electronic sentinel device for personnel that is easy to inspect and maintain. Background Technology

[0002] The electronic sentry system integrates foreign object detection technology based on lidar and foreign object recognition technology based on images. Through multi-sensor perception and big data analysis of foreign objects in tunnel entrances, slopes, and areas crossing railway bridges, it achieves real-time monitoring of foreign object intrusion and encroachment behavior (such as falling rocks, landslides, debris flows, projectiles, and falling objects). Due to the use of multi-sensor fusion detection technology and the combination of big data multi-sample analysis, it can filter out the effects of severe weather such as rain, snow, and fog, resulting in high accuracy, low false alarm rate, and all-weather operation.

[0003] For optimal effectiveness, electronic sentry devices are typically located at high elevations. However, maintenance requires external ladders or climbing devices, necessitating personnel to reach these locations. This process is cumbersome, requiring personnel to prepare bulky climbing equipment, making maintenance of multiple sentry devices in different locations arduous. Furthermore, setting up and retrieving these climbing devices adds to the complexity of the maintenance process. Therefore, there is an urgent need to design a personnel-friendly electronic sentry device for easy maintenance to address these issues. Utility Model Content

[0004] The technical problem to be solved by this utility model is that by setting up an electronic sentry that can be raised and lowered, the electronic sentry can be inspected and maintained without the need for external ladders or other climbing devices.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an electronic sentry device for personnel that is easy to inspect and maintain, including: a pole, a top plate, a movable plate, a sentry body, and a lifting mechanism;

[0006] The top plate is disposed on the top of the upright, and a through opening is provided on the top plate. A first guide wheel is provided on the top plate near the through opening, and a second guide wheel is provided at the upper edge of the top plate.

[0007] The lifting mechanism is located at the bottom of the pole. One end of the lifting mechanism is connected to the output end of the lifting rope. The other end of the lifting rope passes through the second guide wheel and the first guide wheel in sequence, passes through the through hole, extends to the bottom of the top plate, and is connected to the tightening rope.

[0008] The top of the movable plate is provided with a connecting seat, the tightening rope is connected to the connecting seat, and the sentry body is provided at the bottom of the movable plate;

[0009] The bottom of the top plate is provided with a limiting seat, and the limiting seat has a limiting groove. A contact-type charging base is provided in the limiting groove. The top of the moving plate is provided with a snap-fit ​​seat corresponding to the limiting groove. The top of the snap-fit ​​seat is provided with a charging head corresponding to the charging base. The charging head is electrically connected to the sentry body. When the moving plate moves upward and the snap-fit ​​seat is inserted into the limiting groove, the charging base and the charging head engage.

[0010] As a preferred technical solution of this utility model, the lifting mechanism includes a mounting frame, a lifting motor, and a lifting roller. The mounting frame is disposed at the bottom of the upright, the lifting motor is disposed on the mounting frame, the output end of the lifting motor is connected to the lifting roller, and the end of the lifting rope is fixedly connected to the lifting roller.

[0011] By adopting the above technical solution, a lifting motor is set up to provide power to drive the lifting roller to rotate. As the lifting roller rotates, the lifting rope can be wound onto the lifting roller, thereby completing the upward movement of the moving plate. The lifting motor is a brake asynchronous motor.

[0012] In a preferred embodiment of this utility model, the movable plate is connected to a connecting plate, the connecting plate is connected to a vertical plate, and the vertical plate is provided with a plurality of limiting wheels, which are in contact with the vertical rod.

[0013] By adopting the above technical solution, and by setting up a connecting plate, a vertical plate, and limit wheels, the moving plate is supported by the uprights, thus ensuring the stability of the moving plate's up and down movement.

[0014] As a preferred technical solution of this utility model, the upright is provided with a limiting groove, and the limiting wheel is slidably connected in the limiting groove.

[0015] By adopting the above technical solution and setting limit grooves in conjunction with limit wheels, the stability of the moving plate's up and down movement is further ensured.

[0016] As a preferred embodiment of this utility model, a fixing seat is provided at the bottom of the upright.

[0017] By adopting the above technical solution and setting a fixed base, the device can be installed at the required site.

[0018] As a preferred embodiment of this utility model, the charging base is a magnetic contact charging base, and the charging head is a magnetic contact charging head.

[0019] By adopting the above technical solution, since the charging base is a magnetic contact charging base and the charging head is a magnetic contact charging head, it is ensured that the charging base and the charging head can be more easily connected to supply power.

[0020] The beneficial effects of this utility model are reflected in:

[0021] 1. By setting up a lifting mechanism, power is provided to drive the lifting rope to lift. A first guide wheel and a second guide wheel guide the lifting rope, which then passes through the through-hole and extends below the top plate. It connects to the moving plate via a connecting seat, allowing the lifting mechanism to provide upward force and move the moving plate upwards. Combined with gravity, when the moving plate needs to move downwards, the lifting mechanism releases the upward force on the moving plate, allowing gravity to move it downwards. Through this method, the moving plate, under the combined action of gravity and the lifting mechanism... It can move up and down, allowing the sentry body to move vertically under the influence of gravity and the lifting mechanism. When maintenance is required, the lifting mechanism releases the upward force, and the sentry body moves downward under gravity for maintenance. After maintenance is completed, the stretching mechanism moves the sentry body upward for normal operation. In this way, maintenance can be performed on the electronic sentry without the need for external ladders or other climbing devices, reducing the workload and complexity for maintenance personnel.

[0022] 2. By setting a limiting insert and a locking seat, the position of the moving plate can be limited when it moves upward to the bottom of the top plate. This prevents the sentry body from shaking due to external airflow or other factors during normal operation. In addition, with the charging base and charging head, the sentry body can be powered when they are connected. During maintenance, the power is automatically cut off as the sentry body moves downward.

[0023] 3. Since the lifting mechanism is located at the bottom of the pole, it is convenient to inspect and maintain the lifting mechanism. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Combined with appendix Figure 1-8 As shown, an electronic sentry device for personnel that is easy to inspect and maintain includes a pole 1, a limiting groove 101, a top plate 2, a through opening 201, a movable plate 3, a connecting seat 301, a connecting plate 302, a standing plate 303, a limiting wheel 304, a sentry body 4, a mounting frame 5, a lifting motor 6, a lifting roller 7, a lifting rope 8, a tightening rope 9, a first guide wheel 10, a second guide wheel 11, a fixed seat 12, a limiting insert 13, a limiting groove 1301, a charging seat 1302, a snap-fit ​​seat 14, and a charging head 1401.

[0035] Combined with appendix Figure 1-8As shown, an electronic sentry device for personnel, which is easy to inspect and maintain, includes: a pole 1, a top plate 2, a movable plate 3, a sentry body 4, and a lifting mechanism. The top plate 2 is located on the top of the pole 1 and has a through opening 201. A first guide wheel 10 is located on the top plate 2 near the through opening 201, and a second guide wheel 11 is located at the upper edge of the top plate 2. The lifting mechanism is located at the bottom of the pole 1. One end of the lifting mechanism is connected to a lifting rope 8, and the other end of the lifting rope 8 passes through the second guide wheel 11 and the first guide wheel 10, passes through the through opening 201, extends to the bottom of the top plate 2, and is connected to a tightening rope 9. A connecting seat 301 is located on the top of the movable plate 3, and the tightening rope 9 is connected to the connecting seat 301. The sentry body 4 is located at the bottom of the moving plate 3, connected by a connector 301. A limiting seat 13 is provided at the bottom of the top plate 2, with a limiting groove 1301 on the limiting seat 13. A contact-type charging base 1302 is provided in the limiting groove 1301. A locking seat 14 corresponding to the limiting groove 1301 is provided at the top of the moving plate 3, with a charging head 1401 corresponding to the charging base 1302 on the top of the locking seat 14. The charging head 1401 is electrically connected to the sentry body 4. When the moving plate 3 moves upward, causing the locking seat 14 to engage with the limiting groove 1301, the charging base 1302 and the charging head 1401 engage. A lifting mechanism is provided to provide power to drive the lifting rope. 8. The lifting mechanism guides the lifting rope 8 by setting the first guide wheel 10 and the second guide wheel 11. After being guided, the lifting rope 8 passes through the through-hole 201 and extends below the top plate 2, connecting to the moving plate 3 via the connecting seat 301. This allows the lifting mechanism to provide upward force, driving the moving plate 3 upward. Combined with gravity, when the moving plate 3 needs to move downward, the lifting mechanism releases the upward force on the moving plate 3, allowing it to move downward under gravity. Through this method, the moving plate 3 can move up and down under the influence of gravity and the lifting mechanism, thus enabling the sentry body 4 to move up and down under the influence of gravity and the lifting mechanism. 4. During maintenance, the lifting mechanism releases the upward force, and the sentry body 4 moves downward under gravity, allowing for maintenance. After maintenance, the stretching mechanism moves the sentry body 4 upward for subsequent normal operation. This method eliminates the need for external ladders or other climbing devices, reducing the workload and complexity for maintenance personnel. By using a limiting insert 13 in conjunction with a locking seat 14, the position of the moving plate 3 is limited when it moves upward to the bottom of the top plate 2, preventing interference with the sentry body 4 during normal operation.Due to external airflow or other factors, it may shake. In addition, with the charging base 1302 and charging head 1401, when they are connected, power can be provided for the operation of the sentry body 4. Furthermore, during maintenance, the power is automatically cut off as the sentry body 4 moves downwards. Since the lifting mechanism is located at the bottom of the pole 1, it is convenient for maintenance and repair.

[0036] Combined with appendix Figure 1-8 As shown, the lifting mechanism includes a mounting frame 5, a lifting motor 6, and a lifting roller 7. The mounting frame 5 is located at the bottom of the upright 1, the lifting motor 6 is mounted on the mounting frame 5, and the output end of the lifting motor 6 is connected to the lifting roller 7. The end of the lifting rope 8 is fixedly connected to the lifting roller 7. The moving plate 3 is connected to a connecting plate 302, and the connecting plate 302 is connected to an upright plate 303. The upright plate 303 is provided with several limiting wheels 304, which contact the upright 1. The upright 1 is provided with a limiting groove 101, and the limiting wheels 304 are slidably connected in the limiting groove 101. A fixed seat 12 is provided at the bottom of the upright 1. The charging seat 1302 is a magnetic contact charging seat, and the charging head 1401 is a magnetic contact charging head. By setting the lifting motor 6, a dynamic charging mechanism is provided. The force drives the lifting roller 7 to rotate. As the lifting roller 7 rotates, the lifting rope 8 can be wound onto the lifting roller 7, thereby completing the upward movement of the moving plate 3. The lifting motor 6 is a brake asynchronous motor. By setting the connecting plate 302, the upright plate 303 and the limiting wheel 304, the moving plate 3 is supported by the upright 1 to ensure the stability of the moving plate 3's up and down movement. By setting the limiting groove 101, in conjunction with the limiting wheel 304, the stability of the moving plate 3's up and down movement is further ensured. By setting the fixed seat 12, the device can be installed in the required site. Since the charging seat 1302 is a magnetic contact charging seat and the charging head 1401 is a magnetic contact charging head, it is ensured that the charging seat 1302 and the charging head 1401 can be more easily connected to supply power.

[0037] Working principle: When maintenance is required, the upward force of the lifting motor 6 on the moving plate 3 is released. Under the action of gravity, the moving plate 3 and the sentry body 4 move downward, allowing maintenance to be performed on the sentry body 4. After maintenance is completed, the lifting motor 6 pulls the moving plate 3 upward via the lifting rope 8. As the moving plate 3 moves upward, it drives the sentry body 4 upward. When the sentry body 4 reaches the bottom position of the top plate 2, the position of the sentry body 4 is adjusted by the limiting insert 13 and the locking seat 14. The charging base 1302 is positioned to engage with the charging head 1401 to supply power to the sentry body 4. Preferably, the charging base 1302 is powered by an external power source. Then, the sentry body 4 can start working. During the up-and-down movement of the sentry body 4, the limiting wheel 304 and the limiting groove 101 prevent the sentry body 4 from shifting due to external influences. This ensures the stability of the up-and-down movement of the sentry body 4 and ensures that the charging head 1401 can accurately engage with the charging base 1302.
