Description
Technical Field
[0001] The present invention relates to the field of cloud service monitoring technology, and in particular to a cloud service device for monitoring campus student safety. Background Art
[0002] In today's campus environment, student safety remains a top priority. With the continuous development of society, campuses have continued to expand, evolving from a single campus to a multi-campus structure. Campus land has increased significantly, and new teaching buildings, laboratory buildings, gymnasiums, and other structures have sprung up like mushrooms after rain. At the same time, the student population is increasing, with the number of new students climbing year by year. Students from different grades and majors gather on campus, significantly increasing the density of people on campus.
[0003] However, the campus area is vast, and although a large number of security monitoring equipment have been installed accordingly, equipment wear and tear is inevitable over time. Taking the teaching buildings on campus as an example, each building is often equipped with a large number of monitoring equipment, distributed in corridors, classrooms, stairwells and other locations. Once some equipment fails, the maintenance work is extremely cumbersome. Since the monitoring equipment is usually installed at high places, maintenance personnel need to use escalators to carry out operations. Every time maintenance is performed, maintenance workers have to spend a lot of time and energy to carry the escalator to the designated location, and then disassemble and repair the equipment. The entire process is not only time-consuming, but also greatly increases the workload of maintenance personnel, bringing many inconveniences to the daily maintenance of campus monitoring equipment, and seriously affecting the timely repair and stable operation of the campus security monitoring system. The present invention proposes a campus student safety monitoring cloud service device to alleviate the above-mentioned technical problems existing in the prior art. Summary of the Invention
[0004] The purpose of the present invention is to solve the problem in the prior art that the campus area is vast, and although a large number of security monitoring equipment have been installed accordingly, equipment wear and tear is inevitable over time. Taking the teaching buildings on campus as an example, each building is often equipped with a large number of monitoring equipment, which are distributed in corridors, classrooms, stairwells and other locations. Once some equipment fails, the maintenance work is extremely cumbersome. Since the monitoring equipment is usually installed at high places, maintenance personnel need to use escalators to perform operations. Every time maintenance is performed, maintenance workers have to spend a lot of time and energy to carry the escalator to the designated location, and then disassemble and repair the equipment. The whole process is not only time-consuming, but also greatly increases the workload of maintenance personnel, bringing many inconveniences to the daily maintenance of campus monitoring equipment, and seriously affecting the timely repair and stable operation of the campus security monitoring system. A campus student safety monitoring cloud service device is proposed.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
[0006] A campus student safety monitoring cloud service device includes a fixed box, a bump motor is fixedly installed above the fixed box, the output end of the bump motor is fixedly connected to a winding roller, a winding rope is wound around the surface of the winding roller, one end of the winding rope is fixedly connected to a hanging card, and the hanging card is used to hang a hook frame above the monitoring body, one end of the winding roller is transmission-connected to a second bevel gear, the second bevel gear is meshedly connected to a first bevel gear, the first bevel gear is transmission-connected to a first threaded rod, the first threaded rod is threadedly connected to a first clamping block, the end of the first threaded rod away from the first clamping block is threadedly connected to the second clamping block, the first bevel gear is transmission-connected to a rotating block, and the rotating block is transmission-connected to a rotating plate.
[0007] The above technical solution further includes:
[0008] The winding roller is connected to the first belt, and the end of the first belt away from the winding roller is connected to the second bevel gear. The first bevel gear passes through the fixed box and is connected to the second belt. The second belt is connected to the first threaded rod at the side away from the first bevel gear. The first bevel gear is connected to the third belt, and the end of the third belt away from the first bevel gear is connected to the rotating block. The rotating block is connected to the fourth belt, and the end of the fourth belt away from the rotating block is connected to the rotating plate. A connecting block for rotating the rotating plate is provided under the fixed box.
[0009] A convex block for being clamped under the card cover is provided above the convex block motor, and a second threaded rod is provided under the card cover. The second threaded rod is threadedly connected with a cleaning strip, and the cleaning strip is used to clean dirt on the surface of the tempered glass plate.
[0010] A screw threaded onto the top of the hanging clip allows maintenance personnel to easily control the connection between the clip and the hook. During maintenance, simply twist the screw to release the clip from the hook, allowing for easy removal of the monitor. Once maintenance is complete, twist the screw in the opposite direction to quickly secure the clip to the hook, ensuring the monitor is securely placed. This simple operation and reliable connection improve the efficiency of maintenance and equipment resets.
[0011] A solar panel is fixedly attached to the top of the card cover. By attaching the solar panel to the top of the card cover, it effectively collects solar energy to power the device. Whether the fixed box is installed indoors or outdoors, this method allows for sustainable energy generation. Indoors, the solar panel can be moved to a sunny location to collect energy, while outdoors, it can directly utilize solar energy. This is not only energy-efficient and environmentally friendly, but also ensures that the monitoring cloud service device can continue to operate without an external power source or in the presence of unstable power supplies, ensuring the continuity of monitoring work in open-air areas on campus.
[0012] The side of the cover is equipped with a support block for the second threaded rod to rotate. The support block provides a stable support point for the second threaded rod, ensuring that the second threaded rod remains stable during rotation. When cleaning the tempered glass surface, the second threaded rod drives the cleaning bar to rotate. The stable support ensures the accuracy and effectiveness of the cleaning action, preventing incomplete cleaning or damage to the equipment due to shaking of the threaded rod. This effectively maintains the cleanliness of the tempered glass surface and ensures the clarity of the monitoring data collected.
[0013] The fixed box is equipped with a hanging bracket on its side. This bracket facilitates installation and hanging. In open-air areas of a campus, the fixed box can be flexibly mounted on appropriate locations, such as poles or building walls, based on actual monitoring needs. This design enhances the convenience and flexibility of equipment installation, helps expand the monitoring range, better cover every corner of the campus' open-air areas, and improves the comprehensiveness of campus security monitoring.
[0014] The fixed box is fixedly connected to the outer shell, and the outer shell is rotatably connected to a rotating column inside. This rotating column is used to retract the auxiliary rope. The cooperation between the rotating column and the outer shell enables precise control of the retraction and retraction of the auxiliary rope during the descent and ascent of the monitoring body. During descent, the rotating column extends the auxiliary rope to ensure a smooth descent of the monitoring body. During ascent, the retracted auxiliary rope rotates in the opposite direction, providing auxiliary pulling force for the monitoring body to smoothly return to the fixed box and be firmly fixed. This structure enhances the stability of the monitoring body during the raising and lowering process, protects the equipment, and reduces the risk of damage caused by shaking.
[0015] The rotating block is rotatably connected to the side surface of the fixed box. A fixed block is fixedly connected inside the fixed box. The fixed block is rotatably connected to the second bevel gear.
[0016] The side of the first clamp is provided with seismic isolation cotton for clamping the monitoring body, and the side of the second clamp is also provided with seismic isolation cotton for clamping the monitoring body. The seismic isolation cotton plays a role in buffering and shock absorption when the first and second clamps clamp the monitoring body. The open-air environment of the campus is complex, and the equipment may be affected by external vibrations. Seismic isolation cotton can effectively reduce the transmission of vibrations to the monitoring body, prevent the monitoring body from damaging the internal precision components due to vibration, extend the service life of the equipment, ensure the stable operation of the monitoring body in various environments, and improve the accuracy of monitoring data collection.
[0017] The present invention has the following beneficial effects:
[0018] 1. This invention significantly improves maintenance efficiency: With the campus student safety monitoring cloud service device, maintenance personnel no longer need to spend a lot of time carrying escalators to the bottom of the high-altitude monitoring equipment. By controlling the rotation of the bump motor at the ground level, a series of mechanical structures, such as the retracting roller that extends and rewinds the rope, can quickly lower the monitoring unit to the maintenance personnel. This process greatly shortens the pre-repair preparation time, allowing maintenance personnel to quickly carry out equipment inspection and maintenance work, significantly improving the overall efficiency of campus monitoring equipment maintenance, and ensuring that the safety monitoring system can resume normal operation in the shortest possible time.
[0019] 2. In the present invention, in conventional maintenance methods, maintenance personnel need to repeatedly move the escalator and work at height, which is labor-intensive and poses safety risks. The emergence of the equipment of the present invention has changed this situation. Maintenance personnel only need to operate the control cam motor on the ground, and subsequent operations such as equipment lowering and fixing are automatically completed by the mechanical structure. After the maintenance is completed, the reverse operation can easily return the monitoring body to its original position and fix it. This greatly reduces the physical exertion and workload of maintenance personnel, reduces the safety risks during the maintenance process, and reduces the delays that may be caused by maintenance difficulties, ensuring that the daily maintenance work of campus security monitoring equipment can be carried out smoothly and efficiently.

[0039] In one embodiment, for the above-mentioned fixing frame 3 , a fixing frame 3 for hanging is provided on the side of the fixing box 1 .
[0040] In this embodiment, the mounting bracket 3 facilitates the installation and suspension of the fixed box 1. In open-air areas of a campus, the fixed box 1 can be flexibly mounted on a suitable location, such as a pole or a building wall, using the mounting bracket 3, based on actual monitoring needs. This design enhances the convenience and flexibility of equipment installation, helps expand the monitoring range, better covers every corner of the campus's open-air areas, and improves the comprehensiveness of campus security monitoring.
[0041] In one embodiment, for the above-mentioned rotating column 28 , the fixed box 1 is fixedly connected to the outer shell 27 , and the outer shell 27 is rotatably connected to the rotating column 28 . The rotating column 28 is used to retract the auxiliary rope 29 .
[0042] In this embodiment, the cooperation between the rotating column 28 and the housing 27 precisely controls the retraction and retraction of the auxiliary rope 29 during the descent and ascent of the monitoring unit 14. During descent, the rotating column 28 extends the auxiliary rope 29, ensuring a smooth descent of the monitoring unit 14. During ascent, the retracted auxiliary rope 29 rotates in the opposite direction, providing auxiliary tension for the monitoring unit 14, allowing it to smoothly return to the interior of the fixed box 1 and be securely fixed. This structure enhances the stability of the monitoring unit 14 during the raising and lowering process, protecting the equipment and reducing the risk of damage caused by shaking.
[0043] In one embodiment, the rotating block 22 is rotatably connected to the side of the fixed box 1 , a fixed block 10 is fixedly connected inside the fixed box 1 , and the fixed block 10 is rotatably connected to the second bevel gear 9 .
[0044] In one embodiment, for the monitoring body 14 , the side of the first clamping block 12 is provided with shock-isolating cotton for clamping the monitoring body 14 , and the side of the second clamping block 13 is also provided with shock-isolating cotton for clamping the monitoring body 14 .
[0045] In this embodiment, the isolation pads provide a cushioning effect when the first and second clamping blocks 12, 13 clamp the monitoring unit 14. Campuses are exposed to complex outdoor environments, and equipment may be affected by external vibrations. The isolation pads effectively reduce the transmission of vibrations to the monitoring unit 14, preventing damage to the delicate components within the monitoring unit 14. This extends the equipment's lifespan, ensures stable operation of the monitoring unit 14 in a variety of environments, and improves the accuracy of monitoring data collection.
[0046] The working principle of a campus student safety monitoring cloud service device in the present invention is to first install a fixed box 1 according to the needs of the campus. If it is installed in a classroom or indoor space, the solar panel 4 can be removed from above the card cover 2 and installed in a place with sunlight. If it is installed outdoors, the solar panel 4 can be installed above the card cover 2 using a fixed frame 3 for continuous absorption of solar energy.
[0047] After installing the fixed box 1, the maintenance master can see which equipment is damaged and needs to be repaired according to the background information, and then come to the bottom of the corresponding fixed box 1. At this time, the monitoring body 14 is inside the fixed box 1. Then, the bump motor 5 is controlled on the ground to rotate. After the bump motor 5 rotates, it will drive the retraction roller 6 to rotate. The retraction roller 6 rotates to extend the retraction rope 18 on its surface. At the same time, the rotation of the retraction roller 6 will use the first belt 7 to drive the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 will rotate with the first bevel gear 8 is engaged, the rotation of the first bevel gear 8 will use the second belt 20 to drive the first threaded rod 11 to rotate, the rotation of the first threaded rod 11 will move the first clamping block 12 and the second clamping block 13 that clamp the stable monitoring body 14 away from each other, so that the monitoring body 14 is out of a stable state, and then the rotation of the first bevel gear 8 will use the third belt 21 to drive the rotating block 22 to rotate, and the rotating block 22 continues to use the fourth belt 23 to drive one end of the rotating plate 24 to rotate, thereby preparing for the monitoring body 14 to fall from the bottom of the fixed box 1. As the bump motor 5 continues to rotate, The maintenance worker then turns the screw 17 so that the hanging card 16 is no longer squeezed and the hanging card 16 can be pulled out from the side of the hook 15. Then, one end of the auxiliary rope 29 with magnetic adsorption is removed and maintenance can be carried out. After the maintenance, the auxiliary rope 29 can be magnetically adsorbed on one side of the monitoring body 14, and then the hanging card 16 can be clamped on the surface of the hook frame 15, and then the threaded nail 17 is screwed in the opposite direction so that the retracting rope 18 can smoothly lift the monitoring body 14, and then, under the reverse contraction of the rotating column 28 and the auxiliary force of the side of the auxiliary rope 29, it finally rises to the inside of the fixed box 1 and is fixed by the first clamping block 12 and the second clamping block 13 and covered by the cover of the rotating plate 24, and continues to work.
[0048] In the indoor monitoring body 14, the upper solar panel 4 can be set in a place with sunlight, and the solar panel 4 can be used to collect solar energy. The fixed box 1 that is originally set outside can directly set the solar panel 4 to collect solar energy. After collecting solar energy, the motor under the card cover 2 can be controlled to rotate. The rotation of the card cover 2 will drive the second threaded rod 25 to rotate. As the second threaded rod 25 rotates, the cleaning bar 26 will clean the surface of the tempered glass plate 19, thereby preventing the surface of the tempered glass plate 19 from blurring and affecting the collection of data. When the cleaning bar 26 rotates to one side of the second threaded rod 25, the motor under the control card cover 2 is rotated in the opposite direction, thereby once again realizing the cleaning of the surface of the tempered glass plate 19. It is worth mentioning that the outer shell 27 is tempered and matched with the fixed box 1 to further protect the safety of the monitoring body 14 inside it, reducing damage to it.
[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
