Description

Technical Field

[0001] This utility model belongs to the field of monitoring equipment, specifically relating to a security monitoring device for smart parks. Background Technology

[0002] With the rapid development of industrial automation, smart security and consumer electronics, the application scenarios of adjustable equipment brackets are becoming increasingly widespread. For example, the installation of equipment such as surveillance cameras, industrial sensors and displays all rely on support structures with flexible adjustment functions. In smart park environments, security monitoring systems, as key infrastructure, require equipment to achieve comprehensive and high-precision monitoring in order to adapt to dynamic security needs.

[0003] In existing technologies, monitoring equipment is usually mounted on brackets, which are often equipped with rotating joints to provide angle adjustment. However, monitoring equipment installed at high locations is difficult to remove quickly, increasing maintenance difficulty and time costs, and affecting timely maintenance and upgrades. At the same time, once the monitoring equipment is raised to a high place, it is difficult to fix it quickly and is susceptible to environmental factors such as wind and vibration, which can cause the equipment to sway or shift, thereby affecting the stability and quality of the monitoring image.

[0004] Therefore, existing technologies suffer from the problems of inconvenience in fixing monitoring equipment at high locations and difficulty in removing and retrieval. There is an urgent need for a device that can quickly locate, lock, and lower the equipment to improve its ease of use and stability, thereby meeting the security monitoring needs of smart parks and similar scenarios. Utility Model Content

[0005] In order to overcome the problems of inconvenience in fixing monitoring equipment at high places and difficulty in removing and unloading existing technologies, a security monitoring device for smart parks is proposed.

[0006] The technical solution of this utility model is as follows: a security monitoring device for smart parks, including a base box; a U-shaped plate is fixedly connected to the upper left part of the base box, a vertical frame is fixedly connected to the upper right part of the base box, a first groove is opened through the right end of the vertical frame, a sliding column is slidably provided on the inner wall of the first groove, a box is fixedly connected to the right end of the sliding column, a motor is installed in the box, a rotating rod is fixedly connected to the lower end of the motor output shaft, and a camera is fixedly connected to the lower end of the rotating rod. Limiting blocks are fixed to both sides of the inner wall of the frame. The ends of the two limiting blocks that are close to each other are provided with evenly distributed grooves. An adjustment mechanism is provided between the two limiting blocks. A protrusion is installed on the adjustment mechanism, and the protrusion and the groove are matched. The adjustment mechanism is equipped with a rope pulling mechanism, and rotating cylinders are rotatably installed through both sides of the bottom box. The rope pulling mechanism is connected to the rotating cylinders. One side of the inner wall of the frame has indicator grooves that are evenly distributed in the vertical direction. When the lower end of the fixing block is flush with the upper end of any indicator groove, the protrusion will enter the groove when the fixing block moves downward.

[0007] Furthermore, the top plate is fixed to the upper end of the U-shaped plate and the vertical frame, and the bottom box, U-shaped plate, vertical frame and top plate together form a cuboid structure.

[0008] Furthermore, the adjustment mechanism includes a U-shaped block, a protective frame, a first electric cylinder, an adjustment block, a fixed block, and a connecting rod; a U-shaped block is provided between the two limiting blocks, with the U-shaped block opening downwards, and a protective frame is fixedly connected to both sides of the inner wall of the U-shaped block, and a first electric cylinder is fixedly connected to the inner wall of the protective frame, with a fixed block fixedly connected to the lower end of the output shaft of the first electric cylinder, and adjustment blocks are hinged to the lower parts of both sides of the first electric cylinder, with one end of a connecting rod hinged to both sides of the fixed block, and the other end of the connecting rod hinged to the middle of the side wall of the adjustment block, with a protrusion fixed to the lower part of the end of the adjustment block away from the fixed block.

[0009] Furthermore, the rope-pulling mechanism includes a fixed frame, a through hole, a second groove, a first U-shaped seat, a first guide wheel, a second U-shaped seat, and a second guide wheel. The fixed frame is fixedly connected to the upper part of the inner wall of the upright frame. A through hole is opened through the center of the upper end of the fixed frame. A second groove is opened through the upper part of one side of the upright frame. A first U-shaped seat is fixedly connected to the bottom surface of the inner wall of the second groove. First guide wheels are rotatably installed on both sides of the inner wall of the first U-shaped seat. A second U-shaped seat that is evenly distributed in the vertical direction is fixedly connected to one side of the upright frame. Second guide wheels are rotatably installed on both sides of the inner wall of the second U-shaped seat. One end of a rope is fixedly connected to the upper end of the U-shaped block. The other end of the rope passes through the through hole, the groove of the first guide wheel, and the grooves of multiple second guide wheels in sequence and is fixedly connected to the side wall of the rotating cylinder.

[0010] Furthermore, bolts are threaded onto the inner wall of the rotating cylinder, and one end of each bolt is fixed to a turntable.

[0011] Furthermore, an internally threaded cylinder is fixed to the lower end of the base box, and the internally threaded cylinder is compatible with the bolts.

[0012] Furthermore, the ends of the two limiting blocks that are close to each other fit together with the two sides of the U-shaped block.

[0013] Furthermore, a positioning block is fixed to the upper end of the box body, and a slot is opened at one end of the positioning block near the vertical frame. A second electric cylinder is fixed to the upper part of the other side of the inner wall of the vertical frame, and the output shaft of the second electric cylinder passes through the vertical frame and extends into the slot on the positioning block.

[0014] The beneficial effects of this utility model are: 1. When the camera rises to the target height with the sliding column, the first electric cylinder in the adjustment mechanism is activated, and its output shaft pushes the fixed block downward. The fixed block drives the adjustment block to unfold outward through the connecting rods hinged on both sides, so that the protrusion at the lower end of the adjustment block is precisely engaged in the groove of the limiting block. At this time, the sliding column is clamped and fixed by the limiting block and the protrusion, realizing the rapid positioning and locking of the monitoring equipment at high altitudes, and solving the problem of difficulty in rapid fixation in the existing technology. 2. The setting of the indicator groove ensures that the position of the protrusion and the groove correspond when the fixed block descends. It can be observed through the camera that when the lower end of the fixed block is flush with the upper end of the indicator groove, the protrusion falls into the groove, which further improves the positioning accuracy. 3. When the monitoring equipment needs to be removed, the first electric cylinder retracts, causing the fixed block to move upward. The connecting rod pulls the adjusting block inward, and the protrusion disengages from the groove of the limit block, releasing the lock on the sliding column. At the same time, the rotating turntable drives the rotating cylinder to rotate. At this time, the rope loosens, and the sliding column slides down the first groove under the action of gravity, causing the box and camera to quickly descend to the lowest position, solving the problem of the difficulty in quickly removing the security monitoring equipment in the smart park. 4. The positioning block at the top of the box cooperates with the second electric cylinder on the inner wall of the frame. When the equipment is raised to the position, the output shaft of the second electric cylinder extends into the slot of the positioning block to form a mechanical limit, which further enhances the fixed reliability of the monitoring equipment at high positions and avoids displacement caused by vibration and other factors.

A rotating rod 32 is fixedly connected to the lower end of the output shaft of the motor 31. A camera 7 is fixedly connected to the lower end of the rotating rod 32. Limiting blocks 11 are fixed to both sides of the inner wall of the frame 3. The ends of the two limiting blocks 11 that are close to each other are provided with evenly distributed grooves 12. An adjustment mechanism is provided between the two limiting blocks 11. A protrusion 19 is installed on the adjustment mechanism. The protrusion 19 and the groove 12 are compatible. A rope-pulling mechanism is installed on the adjustment mechanism, and rotating cylinders 8 are rotatably installed through both sides of the bottom box 1. The rope-pulling mechanism is connected to the rotating cylinders 8. One side of the inner wall of the frame 3 has an indicator groove 33 that is evenly distributed in the vertical direction. When the lower end of the fixing block 17 is flush with the upper end of any indicator groove 33, the protrusion 19 enters the groove 12 when the fixing block 17 moves downward.

[0019] In use, manually rotate the rotating cylinder 8 to move the stretching mechanism, which can pull the box 6 upward to a suitable height. Turn on the camera 7 to observe the indicator groove 33, so that the lower end of the fixing block 17 is flush with the upper end of any indicator groove 33. Then turn on the adjustment mechanism to make the protrusion 19 enter the inner wall of the groove 12, which can achieve stable placement of the box 6 and the camera 7. When the camera 7 needs to be removed quickly, hold the rotating cylinder 8 and then turn on the adjustment mechanism to move the protrusion 19 out of the inner wall of the groove 12. Under the action of gravity, the camera 7 will fall after you release your hand, making it easy to quickly remove the camera 7 for maintenance.

[0020] Please see Figure 1 In this embodiment, the top plate 4 is fixedly connected to the upper ends of the U-shaped plate 2 and the vertical frame 3. The bottom box 1, U-shaped plate 2, vertical frame 3 and top plate 4 together form a cuboid structure. The top plate 4 connects the U-shaped plate 2 to the top of the vertical frame 3 to form a stable cuboid frame structure, which enhances the structural strength and stability of the overall device. At the same time, it can protect the internal adjustment mechanism, rope pulling mechanism and other components, and prevent external debris from intruding and affecting the operation of the device.

[0021] Please see Figure 1 and Figure 4In this embodiment, the adjustment mechanism includes a U-shaped block 13, a protective frame 14, a first electric cylinder 15, an adjusting block 16, a fixing block 17, and a connecting rod 18. A U-shaped block 13 is positioned between two limiting blocks 11, with the U-shaped block 13 opening downwards. A protective frame 14 is fixed to both sides of the inner wall of the U-shaped block 13. A first electric cylinder 15 is fixed to the inner wall of the protective frame 14. A fixing block 17 is fixed to the lower end of the output shaft of the first electric cylinder 15. Adjusting blocks 16 are hinged to the lower parts of both sides of the first electric cylinder 15. One end of a connecting rod 18 is hinged to both sides of the fixing block 17. The connecting rod 18... The other end is hinged to the middle of the side wall of the adjusting block 16. The protrusion 19 is fixed to the lower part of the end of the adjusting block 16 away from the fixed block 17. The U-shaped block 13 is fitted with the limiting block 11 to ensure that the adjusting mechanism slides stably along the vertical direction of the frame 3. The protective frame 14 protects the first electric cylinder 15 to prevent it from being damaged by external impact. The first electric cylinder 15 drives the fixed block 17 to move up and down. The hinge transmission of the connecting rod 18 drives the adjusting block 16 to swing, so that the protrusion 19 can accurately enter or leave the groove 12 of the limiting block 11, thereby achieving rapid positioning of the height of the camera 7.

[0022] Please see Figure 1 and Figure 5 In this embodiment, the rope-pulling mechanism includes a fixed frame 20, a through hole 21, a second groove 22, a first U-shaped seat 23, a first guide wheel 24, a second U-shaped seat 25, and a second guide wheel 26. A fixed frame 20 is fixedly connected to the upper part of the inner wall of the upright frame 3. A through hole 21 is formed through the center of the upper end of the fixed frame 20. A second groove 22 is formed through the upper part of one side of the upright frame 3. A first U-shaped seat 23 is fixedly connected to the bottom surface of the inner wall of the second groove 22. First guide wheels 24 are rotatably mounted on both sides of the inner wall of the first U-shaped seat 23. A second U-shaped seat 25, evenly distributed in the vertical direction, is fixedly connected to one side of the upright frame 3. Second guide wheels 24 are rotatably mounted on both sides of the inner wall of the second U-shaped seat 25. One end of a rope is fixed to the upper end of the wheel 26 and the U-shaped block 13. The other end of the rope passes through the through hole 21, the groove of the first guide wheel 24, and the grooves of multiple second guide wheels 26 in sequence, and is fixed to the side wall of the rotating cylinder 8. The transmission direction of the rope is changed by the first guide wheel 24 and the second guide wheel 26, reducing the friction between the rope and the inner wall of the frame 3, making the lifting process of the U-shaped block 13 smoother and more stable. The multiple second guide wheels 26 are evenly distributed to ensure that the rope is evenly stressed in the vertical direction, avoiding the U-shaped block 13 from tilting and getting stuck. The rope is connected to the rotating cylinder 8, and the lifting of the U-shaped block 13 can be controlled by rotating the rotating cylinder 8. The operation is convenient and the stability is good.

[0023] Please see Figure 1 and Figure 2 In this embodiment, a bolt 9 is threaded on the inner wall of the rotating cylinder 8, and a turntable 10 is fixed to one end of the bolt 9. The bolt 9 is threadedly connected to the rotating cylinder 8, and then the turntable 10 is manually rotated to facilitate the rotation of the rotating cylinder 8, thereby realizing the winding and unwinding of the rope and adjusting the height of the monitoring equipment.

[0024] Please see Figure 1 and Figure 6 In this embodiment, an internally threaded cylinder 27 is fixedly connected to the lower end of the bottom box 1. The internally threaded cylinder 27 and the bolt 9 are compatible. The internally threaded cylinder 27 and the bolt 9 cooperate. When the bolt 9 is not in use, it can be installed on the inner wall of the internally threaded cylinder 27.

[0025] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the two limiting blocks 11 are close to each other at one end and fit together with the two sides of the U-shaped block 13. The fitting of the limiting blocks 11 and the U-shaped block 13 provides a precise guiding effect for the vertical sliding of the U-shaped block 13, reduces the shaking and offset during the sliding process, and ensures that the protrusion 19 can be accurately aligned with the groove 12 of the limiting block 11.

[0026] Example 2: Please refer to Figure 7 Based on Embodiment 1, this application provides a technical solution: a positioning block 30 is fixedly connected to the upper end of the box body 6. A slot is opened at one end of the positioning block 3 near the vertical frame 3. A second electric cylinder 29 is fixedly connected to the upper part of the other side of the inner wall of the vertical frame 3. The output shaft of the second electric cylinder 29 passes through the vertical frame 3 and extends into the slot on the positioning block 30. By inserting the output shaft of the second electric cylinder 29 into the slot of the positioning block 30, an additional mechanical lock is formed on the box body 6. This locks in conjunction with the locking structure of the protrusion 19 and groove 12 of the adjustment mechanism, achieving double fixation. This further enhances the stability of the monitoring equipment at high altitudes, effectively prevents positional displacement caused by long-term vibration or external force, and improves the safety of equipment use.

[0027] Working principle: When in use, manually rotate the turntable 10 to drive the rotating cylinder 8 to rotate, the rope of the rope mechanism is wound or released, and the rope passes through the through hole 21 of the fixed frame 20, the groove of the first guide wheel 24 and the groove of multiple second guide wheels 26 in sequence, thereby pulling the U-shaped block 13 to slide vertically along the inner wall of the upright frame 3. The U-shaped block 13 drives the box body 6 and the camera 7 to rise or fall to a suitable height through the sliding column 28. At this time, the camera 7 is activated to observe the indicator groove 33 on the inner wall of the frame 3, so that the lower end of the fixed block 17 is flush with the upper end of a certain indicator groove 33. Then, the first electric cylinder 15 of the adjustment mechanism is activated, and its output shaft pushes the fixed block 17 to move downward. The fixed block 17 pulls the adjustment block 16 to swing outward through the connecting rod 18, so that the protrusion 19 at the lower end of the adjustment block 16 is precisely engaged in the groove 12 of the limiting block 11, thereby locking the sliding column 28 and achieving stable fixation of the box 6 and the camera 7. When it is necessary to quickly remove the camera 7, the first electric cylinder 15 retracts, causing the fixed block 17 to move upward, the connecting rod 18 pulls the adjusting block 16 to retract inward, the protrusion 19 disengages from the groove 12, and the lock is released. At this time, hold the rotating cylinder 8 to control the descent speed or let go directly. The box 6 slides down along the first groove 5 under the action of gravity, causing the camera 7 to quickly fall back to the low position. In addition, in embodiment 2, when the box 6 is raised to a fixed position, the output shaft of the second electric cylinder 29 extends out and can pass through the upright frame 3 and be inserted into the slot of the positioning block 30, forming a double fixation with the locking structure of the protrusion 19 and the groove 12, further enhancing the stability of the camera 7 at a high position. When not in use, bolt 9 can be threaded to the internal threaded cylinder 27 at the lower end of the base box 1. When adjusting the height, bolt 9 can be threaded onto the inner wall of the rotating cylinder 8. The rotating cylinder 8 can be rotated manually by turning the turntable 10, which is convenient to use.
