Description

Technical Field

[0001] This invention relates to the field of security monitoring devices, specifically a security monitoring device that is convenient for multi-angle adjustment. Background Technology

[0002] Security monitoring devices can reflect the monitored object in real time, vividly and realistically. They can replace human surveillance for long periods of time in harsh environments, allowing people to see everything that actually happens at the monitored site and save and record it.

[0003] Existing outdoor multi-angle adjustable security monitoring devices are mostly installed on high support columns or the tops of street lamp poles, which cannot achieve all-round monitoring. The field of view is obstructed by the lamp poles or mounting columns, creating blind spots that provide opportunities for criminals. Furthermore, after the angle is adjusted, the camera's field of view is often tilted, making it difficult to maintain a stable and level view during the adjustment process, resulting in poor monitoring image quality. In addition, existing security monitoring devices can only monitor areas below the installation position and cannot monitor high-rise buildings or other areas above the installation position of the monitoring equipment, thus failing to achieve all-round, blind-spot-free recording. Summary of the Invention

[0004] Based on this, the purpose of this invention is to provide a security monitoring device that is convenient for multi-angle adjustment, in order to solve the technical problems of existing outdoor multi-angle adjustable security monitoring devices that cannot achieve all-round monitoring, whose field of view is blocked by lampposts or installation columns, forming blind spots, which are difficult to maintain a stable and horizontal field of view during the adjustment process, resulting in poor monitoring image quality, and that existing security monitoring devices cannot monitor high-rise buildings or other areas above the installation position of the monitoring equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a security monitoring device that is convenient for multi-angle adjustment, comprising a mounting column, a fixed column connected to one side of the mounting column, a vertical rotating motor disposed inside the fixed column, the output end of the vertical rotating motor extending out of the fixed column and connected to a rotating column, a horizontal rotating motor disposed at the upper end of the rotating column and a main control chip disposed at the lower end, the output end of the horizontal rotating motor extending out of the rotating column and connected to a turntable, a rotating platform fixedly connected to the top of the rotating column, the turntable being able to rotate within the rotating platform, cameras facing the same direction being connected to both sides of the top surface of the turntable, a lens rotating motor fixedly connected to the rear end of the camera via a lens rotating motor mounting platform, and a lens module connected to the output end of the lens rotating motor.

[0006] By adopting the above technical solution and designing a multi-axis rotating camera installation structure, the camera can provide all-round monitoring and expand the monitoring range. By splicing and overlapping the recording images of two sets of cameras, the area behind the installation column can be monitored, which solves the problem of blind spots in traditional monitoring equipment. A lens rotation motor is set inside the camera to ensure that the monitoring image can always remain horizontal when the rotation table is adjusted, thus achieving better monitoring results.

[0007] The present invention is further configured such that a zoom camera and an infrared zoom camera are installed inside the lens module, a laser rangefinder is installed inside the camera on one side of the lens module, and multiple sets of lens module support columns are provided on the inner wall of the camera, the front end of the lens module support column is connected to the outer wall of the lens module and is connected to a rotating wheel.

[0008] By adopting the above technical solution, the approximate position of the distance observation target can be determined by the laser rangefinder, making the zoom camera and infrared zoom camera focus faster. In good lighting conditions, the zoom camera can be used to record color images, while in poor lighting conditions, the infrared zoom camera can be used to record black and white images. The lens module support column can ensure the stable rotation of the lens module and improve image quality.

[0009] The present invention is further configured such that a fixing ring is connected to the front end of the camera by screws, an electrically heated glass is provided on the inner side of the fixing ring, and a sealing rubber ring is provided between the electrically heated glass and the camera.

[0010] By adopting the above technical solutions, the electrically heated glass can prevent fogging of the lens inside the camera, which would affect the quality of the monitoring image, and the sealing rubber ring can ensure that the inside of the camera is dry.

[0011] The present invention is further configured such that the camera is fixedly connected to the turntable via a camera linkage.

[0012] By adopting the above technical solution, the camera can be stably fixed using the camera linkage.

[0013] The present invention is further configured such that a wiring conduit connects the two sets of cameras.

[0014] By adopting the above technical solution, the camera, main control chip, and device power supply are connected.

[0015] The present invention is further configured such that the fixing column is fixed to one side of the mounting column by means of a connecting foot at the bottom and a connecting bolt.

[0016] By adopting the above technical solution, the fixing column can be stably fixed to one side of the mounting column using fixing bolts.

[0017] The present invention is further configured such that a protective cover is fixedly connected to the top surface of the rotating platform, and the protective cover is a plane on the side facing the camera.

[0018] By adopting the above technical solution, the protective cover can protect the camera, and the flat protective cover in front of the camera can ensure that the monitoring screen does not be distorted.

[0019] The present invention is further configured such that a counterweight is provided inside the rotating column on the opposite side of the rotating platform, and a power supply is provided inside the fixed column.

[0020] By adopting the above technical solution, the counterweight can ensure the stability of the rotating column during rotation, and the device power supply can provide power to the device.

[0021] The present invention is further configured such that a roller is provided between the rotary table and the turntable.

[0022] By adopting the above technical solution, the roller can ensure the stability of the turntable rotation.

[0023] The present invention is further configured such that conductive slip rings are provided at the connection between the fixed column and the rotating column, at the center of the turntable, and between the lens module and the lens rotating motor.

[0024] By adopting the above technical solution, the conductive slip ring ensures that the device can be connected to power and operate normally.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] 1. This invention designs a multi-axis rotating camera mounting structure. Through the coordinated rotation of horizontal and vertical rotating motors, the camera on the rotating platform can face any position, ensuring all-round monitoring. It can monitor areas higher than the installation position, thus expanding the monitoring range. Controlling the rotation of the rotating platform through the motor rotation is also very convenient, and the control of the rotation angle is also very precise.

[0027] 2. This invention achieves the purpose of monitoring the area behind the installation column by setting two sets of spaced-apart cameras on a rotating platform and splicing and overlapping the recorded images of the two sets of cameras, thus solving the problem of blind spots in traditional monitoring equipment.

[0028] 3. This invention incorporates a lens rotation motor inside the camera. This motor drives the lens to rotate in conjunction with horizontal and vertical rotation motors, ensuring that the monitoring screen remains horizontal when the rotating platform adjusts its angle. This facilitates better observation of the monitoring screen by security personnel and achieves a more effective monitoring result. Attached Figure Description

[0039] The embodiments of the present invention will now be described.

[0040] A security monitoring device that is convenient for multi-angle adjustment, such as Figure 1-8As shown, the device includes a mounting column 1, with a fixed column 2 connected to one side of the mounting column 1. A vertical rotary motor 3 is installed inside the fixed column 2. The output end of the vertical rotary motor 3 extends out of the fixed column 2 and is connected to a rotating column 6. A horizontal rotary motor 7 is installed at the upper end of the rotating column 6, and a main control chip 8 is installed at the lower end. The main control chip 8 can control the device to adjust the angle and cut and splice the monitoring screen. The output end of the horizontal rotary motor 7 extends out of the rotating column 6 and is connected to a turntable 11. A rotating platform 10 is fixedly connected to the top of the rotating column 6. The turntable 11 can rotate within the rotating platform 10. The operation of the vertical rotary motor 3 can cause the rotating column 6 to rotate in the vertical plane, and the operation of the horizontal rotary motor 7 can... The turntable 11 rotates within the rotating platform 10. Since the camera 12 is fixed on the turntable 11, when the vertical rotating motor 3 and the horizontal rotating motor 7 rotate in coordination, the camera 12 can be oriented in any direction to reach the area above the monitoring mounting column 1. Both sides of the top surface of the turntable 11 are connected to cameras 12 facing the same direction. The rear end of the camera 12 is fixedly connected to the lens rotating motor 18 through the lens rotating motor mounting platform 17. When the vertical rotating motor 3 and the horizontal rotating motor 7 rotate, the lens rotating motor 18 rotates in coordination to ensure the stability of the lens module 20. The output end of the lens rotating motor 18 is connected to the lens module 20.

[0041] Please see Figure 1 The camera 12 is fixedly connected to the turntable 11 via the camera connecting rod 14. The camera 12 can be stably fixed via the camera connecting rod 14. A wiring conduit 13 connects the two sets of cameras 12. The wiring conduit 13 passes through wires and signal lines, connecting the camera 12, the main control chip 8, and the device power supply 4. The fixing column 2 is fixed to one side of the mounting column 1 via the connecting foot 5 at the bottom and the connecting bolt. The fixing bolt can stably fix the fixing column 2 to one side of the mounting column 1. The rotating column 6 has a counterweight 9 inside on the opposite side of the rotating table 10. The device power supply 4 is installed inside the fixing column 2. The counterweight 9 can ensure the stability of the rotating column 6 during rotation. The device power supply 4 can supply power to the device. Conductive slip rings are provided at the connection between the fixing column 2 and the rotating column 6, the center of the turntable 11, and between the lens module 20 and the lens rotation motor 18. The conductive slip rings ensure that the device can be powered and operated normally.

[0042] Please see Figure 1 and Figure 2 A roller 16 is provided between the rotary table 10 and the turntable 11, which can ensure the stability of the rotation of the turntable 11.

[0043] Please see Figure 1 and Figure 4A protective cover 15 is fixedly connected to the top surface of the rotating platform 10. The protective cover 15 is flat on the side facing the camera 12. The protective cover 15 can protect the camera 12. The flat protective cover in front of the camera 12 can ensure that the monitoring screen does not be distorted.

[0044] Please see Figure 1 and Figure 6 The lens module 20 houses a zoom camera 21 and an infrared zoom camera 22. Inside the camera 12, a laser rangefinder 26 is installed on one side of the lens module 20. Multiple sets of lens module support columns 19 are provided on the inner wall of the camera 12. The front end of the lens module support column 19 is connected to the outer wall of the lens module 20 and is connected to a rotating wheel. The laser rangefinder 26 can determine the approximate position of the distance observation target, making the zoom camera 21 and the infrared zoom camera 22 focus faster. In good lighting conditions, the zoom camera 21 can be used to record color images, and in poor lighting conditions, the infrared zoom camera 22 can be used to record black and white images. The lens module support columns 19 can ensure the stable rotation of the lens module 20 and improve the image quality.

[0045] Please see Figure 6 and Figure 7 The front end of the camera 12 is connected to a fixing ring 24 by screws. An electrically heated glass 23 is provided on the inner side of the fixing ring 24. A sealing rubber ring 25 is provided between the electrically heated glass 23 and the camera 12. The electrically heated glass 23 can prevent the lens inside the camera 12 from fogging up and affecting the quality of the monitoring image. The sealing rubber ring 25 can ensure that the inside of the camera 12 is dry.

[0046] The working principle of this invention is as follows: the vertical rotating motor 3 can make the rotating column 6 rotate in the vertical plane, and the horizontal rotating motor 7 can make the turntable 11 rotate within the rotating platform 10. Since the camera 12 is fixed on the turntable 11, when the vertical rotating motor 3 and the horizontal rotating motor 7 rotate together, the camera 12 can face any direction to reach the area above the monitoring column 1, thus expanding the monitoring range and the rotation angle of the camera 12. When the vertical rotating motor 3 and the horizontal rotating motor 7 rotate, the lens rotating motor 18 rotates in coordination to ensure the stability of the lens module 20 and make the recorded image better. When the two sets of cameras 12 installed at intervals on the turntable 12 face the direction of the mounting column 1, the monitoring image is analyzed and cropped by the main control chip 8 and then spliced ​​to eliminate the image obstruction caused by the mounting column 1, thus achieving the purpose of monitoring without blind spots.
