Description

Technical Field

[0001] This utility model relates to the field of security monitoring technology, specifically a multi-angle security monitoring and positioning device. Background Technology

[0002] As we all know, in the field of security monitoring, the performance of monitoring equipment is directly related to the reliability and effectiveness of security systems. However, existing security monitoring equipment has many undeniable defects in practical applications, which seriously restricts its security effectiveness.

[0003] Traditional security monitoring equipment has significant shortcomings in adjusting horizontal rotation and pitch angles. Most devices have fixed angle settings, and even those that do support adjustment often rely on manual operation or have a limited adjustment range. This not only makes the adjustment process cumbersome but also fails to quickly respond to changes in the monitored target at different heights and locations, making it difficult to meet the timeliness requirements of real-time monitoring for angle adjustment and to quickly respond to dynamic changes in the monitored scene. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-angle security monitoring and positioning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle security monitoring and positioning device, comprising a mounting ring, a fixed ring, a security monitoring body, a pitch adjustment mechanism, and a limiting mechanism. A flange is mounted on the bottom wall of the mounting ring. Multiple mounting holes are provided on the front and rear side walls of the mounting ring. The fixed ring is mounted on the top wall of the mounting ring. A cavity is formed inside the fixed ring, and a gear ring is mounted inside the cavity via a bearing. A first motor is mounted on one end of the bottom wall of the fixed ring. The output end of the first motor extends through the bottom wall of the fixed ring to the cavity, where a pinion is mounted. The pinion and the gear ring mesh with each other. A rotating ring is fixedly mounted on the top wall of the gear ring. The top wall of the rotating ring extends through the top wall of the fixed ring to the outside of the cavity. A connecting plate is mounted on the side wall of the rotating ring. The security monitoring body is mounted on the top wall of the other end of the connecting plate via the pitch adjustment mechanism. A limiting mechanism for limiting the position of the gear ring is mounted on the side wall of the fixed ring.

[0008] Furthermore, the present invention is improved in that the pitch adjustment mechanism includes a second motor, a first U-shaped frame, a rotating shaft, and a second U-shaped frame. The first U-shaped frame is installed on the top wall of the end of the connecting plate away from the rotating ring. The rotating shaft is rotatably installed on the first U-shaped frame. The second motor is installed at one end of the rotating shaft through the side wall of the first U-shaped frame. The second U-shaped frame is fixedly installed on the outer wall of the rotating shaft. The top wall of the second U-shaped frame is connected to the bottom wall of the security monitoring body.

[0009] Furthermore, the present invention is improved in that the limiting mechanism includes a telescopic mechanism and a sector gear. The telescopic mechanism is installed on the outer wall of one end of the fixed ring, and the output end of the telescopic mechanism extends through the side wall of the fixed ring to the cavity where the sector gear is installed. The sector gear and the gear ring are meshed and connected.

[0010] Furthermore, an improvement of this utility model is that the telescopic mechanism is an electric telescopic rod.

[0011] Furthermore, the present invention is improved in that both the first motor and the second motor are servo motors.

[0012] Furthermore, an improvement of this utility model is that the second U-shaped frame and the security monitoring body are fixedly connected by bolts.

[0013] Furthermore, the present invention is improved by providing a sealed bearing between the rotating shaft and the first U-shaped frame.

[0014] Furthermore, the present invention is improved in that the first U-shaped frame, the second U-shaped frame, and the rotating shaft are all made of high-strength aluminum alloy material, and the surface is treated with anti-corrosion.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a multi-angle security monitoring and positioning device, which has the following beneficial effects:

[0017] This multi-angle security monitoring and positioning device features a gear and gear ring meshing transmission structure. Combined with the rotation of the rotating ring, it enables the security monitoring unit to rotate 360 ​​degrees, breaking through the limitations of traditional monitoring equipment's horizontal angle. It can cover all horizontal angles within the monitoring area, avoiding blind spots caused by fixed angles. With the flange and mounting holes of the mounting ring, the device can be installed on flat surfaces such as walls and ceilings, as well as on cylindrical structures such as outdoor brackets, without being limited by specific installation environments. Once the security monitoring unit rotates to the target angle via the horizontal adjustment mechanism, the telescopic mechanism of the limiting mechanism drives the sector gear to extend and mesh with the gear ring. The mechanical locking effect of the sector gear and gear ring firmly restricts the rotation of the gear ring, preventing angular deviation due to external forces such as wind, equipment vibration, or accidental collisions. This ensures stable operation of the security monitoring unit at the set horizontal angle, guaranteeing the accuracy and continuity of the monitoring image.

[0018] This multi-angle security monitoring and positioning device, through its pitch adjustment mechanism and driven by a second motor, can directly drive the rotating shaft to rotate clockwise or counterclockwise by controlling its forward and reverse rotation. This, in turn, drives the security monitoring body to achieve upward or downward pitch adjustment through the second U-shaped frame, making the adjustment direction clear and controllable. Combined with the 360-degree rotation of the horizontal adjustment mechanism, the pitch adjustment mechanism allows the security monitoring body to achieve all-round coverage in three-dimensional space. Whether it is wide-angle monitoring in the horizontal direction or high and low position monitoring in the vertical direction, it can be flexibly adjusted. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4A multi-angle security monitoring and positioning device includes a mounting ring 1, a fixed ring 2, a security monitoring body 3, a pitch adjustment mechanism, and a limiting mechanism. A flange 4 is mounted on the bottom wall of the mounting ring 1. Multiple mounting holes 5 are provided on the front and rear side walls of the mounting ring 1. The fixed ring 2 is mounted on the top wall of the mounting ring 1. A cavity 6 is formed inside the fixed ring 2. A gear ring 7 is mounted in the cavity 6 via a bearing. A first motor 8 is mounted on one end of the bottom wall of the fixed ring 2. The output end of the first motor 8 extends through the bottom wall of the fixed ring 2 to the cavity 6, where a pinion 9 is mounted. The pinion 9 meshes with the gear ring 7. A rotating ring 10 is fixedly mounted on the top wall of the gear ring 7, and the top wall of the rotating ring 10 penetrates the fixed ring. The top wall of the 2 extends to the outside of the cavity 6. A connecting plate 11 is installed on the side wall of the rotating ring 10. The security monitoring body 3 is installed on the top wall of the other end of the connecting plate 11 through the pitch adjustment mechanism. A limiting mechanism for limiting the toothed ring 7 is installed on the side wall of the fixing ring 2. In this embodiment, when in use, firstly, using the flange 4 on the bottom wall of the mounting ring 1, the device is firmly installed in a suitable position, such as a wall, bracket, or room ceiling, using bolts and other connecting parts. The hollow design of the fixing ring 2 allows the fixing ring 2 to be fitted onto the cylindrical support rod. With the help of bolts, the fixing ring 2 and the cylindrical support rod can be connected by multiple mounting holes 5 on the mounting ring 1. The diverse installation methods allow the device to be used in more different environments, whether indoors or outdoors. The device can be easily installed on walls, ceilings, or outdoor brackets and other cylindrical supports, broadening its application range and enabling it to better serve various security monitoring scenarios. After the security monitoring unit 3 is installed, when multi-angle horizontal monitoring is required, the control system starts the first motor 8. The output of the first motor 8 drives the pinion 9 to rotate. Since the pinion 9 meshes with the gear ring 7, the gear ring 7 rotates within the cavity 6 of the fixed ring 2 via bearings, thereby driving the rotating ring 10 on the top wall of the gear ring 7 to rotate. The connecting plate 11 on the side wall of the rotating ring 10 and the security monitoring unit 3, mounted on the connecting plate 11 via a pitch adjustment mechanism, also rotate synchronously, thus achieving a wide range of horizontal adjustment around the central axis of the fixed ring 2, realizing security monitoring... The 360-degree rotation of the main body 3 enables position adjustment. When the security monitoring main body 3 rotates to the target angle, the gear ring 7 can be limited by the limit device to ensure its stability after angle adjustment. To adjust the monitoring pitch angle, the pitch adjustment mechanism is operated to change the pitch state of the security monitoring main body 3 to adapt to monitoring needs at different heights and angles. During monitoring, the security monitoring main body 3 can flexibly switch between horizontal and pitch angles according to the actual monitoring scenario to achieve all-round coverage of the monitoring area. Diverse installation methods allow the equipment to be deployed in more scenarios without being limited by a specific environment, while the flexible angle adjustment function ensures that the equipment can achieve the best monitoring effect in every scenario. This feature of "unrestricted installation and no dead angle adjustment" is truly remarkable.This significantly enhances the practical value of the equipment, enabling it to meet the security needs of various locations such as residential communities, commercial plazas, and industrial parks, greatly expanding its applicability.

[0026] Preferably, in this embodiment, the pitch adjustment mechanism includes a second motor 12, a first U-shaped frame 13, a rotating shaft 14, and a second U-shaped frame 15. The first U-shaped frame 13 is mounted on the top wall of the end of the connecting plate 11 away from the rotating ring 10. The rotating shaft 14 is rotatably mounted on the first U-shaped frame 13. The second motor 12 is mounted on one end of the rotating shaft 14 through the side wall of the first U-shaped frame 13. The second U-shaped frame 15 is fixedly mounted on the outer wall of the rotating shaft 14. The top wall of the second U-shaped frame 15 is connected to the bottom wall of the security monitoring body 3. When it is necessary to adjust the pitch angle of the security monitoring body 3, the second motor 12 is started by the control system. The output end of the second motor 12 will drive the rotating shaft 14 connected to it to rotate. Since the second U-shaped frame 15 is fixedly mounted on the outer wall of the rotating shaft 14, the rotation of the rotating shaft 14 will drive the second U-shaped frame 15 to rotate synchronously, thereby causing the security monitoring body 3 to rotate together with the second U-shaped frame 15. The axis of the rotating shaft 14 is used to adjust the pitch angle. During the adjustment process, the security monitoring body 3 can be tilted up or down by controlling the forward and reverse rotation of the second motor 12. By controlling the running time of the second motor 12, the size of the pitch angle can be precisely controlled, so that the security monitoring body 3 can reach the required monitoring pitch angle. For example, when it is necessary to monitor a high target, the second motor 12 is controlled to rotate forward, driving the security monitoring body 3 to tilt upward. When it is necessary to monitor a low target, the second motor 12 is controlled to rotate in reverse, driving the security monitoring body 3 to tilt downward. The second motor 12 drives the rotating shaft 14 to rotate to achieve pitch adjustment. The operation of the motor has high controllability and can precisely control the rotation angle and speed, so that the pitch angle adjustment of the security monitoring body 3 is more accurate, avoiding the error of manual adjustment. At the same time, the motor drive method responds quickly and can quickly complete the angle adjustment, improving the timeliness of monitoring.

[0027] Preferably, in this embodiment, the limiting mechanism includes a telescopic mechanism and a sector gear 16. The telescopic mechanism is installed on the outer wall of one end of the fixed ring 2. The output end of the telescopic mechanism extends through the side wall of the fixed ring 2 and into the cavity 6 to install the sector gear 16. The sector gear 16 and the gear ring 7 are meshed. When the gear ring 7 drives the rotating ring 10 to rotate to a certain angle, and limiting is required, the telescopic mechanism on the outer wall of one end of the fixed ring 2 performs a telescopic action. The output end of the telescopic mechanism extends and drives the sector gear 16 installed at its end to move, so that the sector gear 16 meshes with the gear ring 7. After the two mesh, the rotation of the gear ring 7 will be blocked by the sector gear 16 and cannot continue to rotate in a direction beyond the limit range, thereby limiting the gear ring 7. When the gear ring 7 needs to return to the allowable range, the output end of the telescopic mechanism retracts, driving the sector gear 16 to disengage from the gear ring 7, and the gear ring 7 can then rotate freely again under the drive of the first motor 8.

[0028] Preferably, in this embodiment, the telescopic mechanism is an electric telescopic rod 17. The electric telescopic rod 17 is driven by a motor and can precisely control the telescopic amount. According to a preset program or real-time signal, the telescopic amount can be controlled within a very small error range. This allows the sector gear 16 to accurately mesh or disengage with the gear ring 7, ensuring the accuracy of the limiting timing and position, and further improving the accuracy of the limiting mechanism in limiting the gear ring 7.

[0029] Preferably, in this embodiment, both the first motor 8 and the second motor 12 are servo motors. The servo motors have built-in encoders that can provide real-time feedback on the position, speed, and other information of the motor shaft, enabling closed-loop control. For the first motor 8, it can precisely control the rotation angle and speed of the pinion 9, thereby precisely controlling the horizontal rotation angle of the gear ring 7, the rotating ring 10, and the security monitoring body 3, ensuring that the horizontal monitoring position is accurate. For the second motor 12, it can precisely control the rotation amount of the rotating shaft 14, enabling the pitch angle adjustment of the security monitoring body 3 to achieve extremely high precision, meeting the precise monitoring requirements of specific targets.

[0030] Preferably, in this embodiment, the second U-shaped frame 15 and the security monitoring body 3 are fixedly connected by bolts. The bolts have strong tightening force and can tightly connect the second U-shaped frame and the security monitoring body 3 together. During the operation of the equipment, whether the pitch adjustment mechanism drives the security monitoring body 3 to adjust the angle, or it is affected by external environment such as wind or vibration, the bolt connection can effectively resist external forces, prevent loosening or relative displacement between the two, ensure that the security monitoring body 3 remains stable during the monitoring process, avoid the monitoring screen shaking or offset due to unstable connection, and ensure the stability of the monitoring effect.

[0031] Preferably, in this embodiment, a sealed bearing is provided between the rotating shaft 14 and the first U-shaped frame 13. The sealing structure of the sealed bearing can prevent external impurities such as dust, water vapor, and oil from entering the bearing and the connection gap between the rotating shaft 14 and the first U-shaped frame 13. During long-term operation of the equipment, especially in outdoor or dusty environments, it can prevent impurities from adhering to the surface of the rotating shaft 14 or entering the bearing mating surface, preventing the rotating shaft 14 from being obstructed and worn due to the accumulation of impurities, and ensuring the smooth rotation of the rotating shaft 14.

[0032] Preferably, in this embodiment, the first U-shaped frame 13, the second U-shaped frame 15, and the rotating shaft 14 are all made of high-strength aluminum alloy and the surface is treated with anti-corrosion. High-strength aluminum alloy has high mechanical strength and can withstand the weight of the security monitoring body 3 and various forces generated during the pitch adjustment process, ensuring that the first U-shaped frame 13, the second U-shaped frame 15, and the rotating shaft 14 are not easily deformed or broken during long-term use and have strong structural stability. At the same time, compared with traditional materials such as steel, aluminum alloy has a lower density and lighter weight, which can reduce the overall load of the equipment, reduce the load requirements on the installation structure, and facilitate the transportation and installation of the equipment.
