Description

Technical Field

[0001] The present invention belongs to the technical field of camera brackets, and in particular relates to an angle-adjustable power grid monitoring camera bracket. Background Art

[0002] Power grid surveillance camera brackets are devices specifically designed to secure and support surveillance cameras. They are widely used in key areas of power systems, such as substations, transmission lines, and distribution facilities, to ensure the safe operation and real-time monitoring of power grid equipment. The design and manufacture of these brackets must fully consider the specific characteristics of the power environment, such as high voltage, strong electromagnetic interference, and harsh weather conditions. Consequently, stringent requirements are imposed on material selection, structural design, and installation methods. Power grid surveillance camera brackets are typically constructed of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure durability and corrosion resistance. These materials not only withstand the elements of outdoor environments but also maintain stability in extreme temperatures, preventing deformation or loosening due to thermal expansion and contraction. Furthermore, the brackets are typically treated with rust- and corrosion-resistant treatments, such as spray coating or galvanizing, to extend their service life. Power grid surveillance camera brackets are designed to balance flexibility and stability. Brackets often feature multi-angle adjustment, enabling the camera to cover a wider monitoring area. Locking mechanisms ensure the camera remains fixed in place after adjustment, preventing movement due to wind or vibration. Some brackets also feature anti-shake features to reduce the impact of external vibration on the surveillance image. In terms of mounting methods, power grid surveillance camera brackets are typically wall-mounted, clamp-mounted, or pole-mounted to suit different scenarios. Wall-mount brackets are suitable for installation on substation walls or equipment cabinets; clamp-mount brackets are commonly used on transmission line towers and are fixed to round or square poles with fasteners; pole-mount brackets are independently installed on the ground and are suitable for monitoring open areas. Regardless of the mounting method, the bracket must be sturdy and reliable, capable of supporting the weight of the camera and its associated equipment. Power grid surveillance camera brackets also need to consider electromagnetic compatibility with the power environment. Due to the strong electromagnetic fields surrounding power grid equipment, the bracket design must avoid becoming a transmission path for electromagnetic interference. Non-magnetic materials or shielding are typically used to minimize the impact on camera signal transmission. Furthermore, the bracket should be installed away from high-voltage live areas to ensure the safety of maintenance personnel. To expand functionality, modern power grid surveillance camera brackets may integrate auxiliary equipment such as solar panel brackets, fill light brackets, or network transmission equipment mounting points to meet the needs of intelligent monitoring. For example, for power transmission line monitoring in remote areas, the bracket may be equipped with a solar power module to provide continuous power to the camera. The bracket design also needs to be easy to maintain, such as featuring a quick-release mechanism to facilitate camera replacement or cleaning. In short, power grid surveillance camera brackets are an integral component of the power grid monitoring system. Their design must balance durability, flexibility, and safety to adapt to the complex and ever-changing power environment. Through appropriate material selection, structural optimization, and installation methods, the bracket can provide stable support for the camera, ensuring efficient operation of the monitoring system and safeguarding power grid security.

[0003] After searching, it was found that a "bracket assembly for fixing a camera" was disclosed in a Chinese patent with authorization announcement number "CN111594731B", which includes a mounting bracket for mounting a camera, wherein a support plate is installed at the bottom of the mounting bracket, a connecting sleeve is fixed to the bottom of the support plate, a sliding rod adapted thereto is passed through the interior of the connecting sleeve, one side of the sliding rod is provided with an external thread, and the threaded part on the sliding rod is connected to an adjusting nut adapted thereto through threaded cooperation; a limiting sleeve is respectively provided at both ends of the connecting sleeve, a second buffer assembly is respectively provided inside the two limiting sleeves, and one of the limiting sleeves is fixed to the outer wall of the sliding rod, and the other limiting sleeve is fixedly connected to the adjusting nut; an arc block is fixed at one end of the sliding rod, the arc block is connected to a supporting cylinder, and the bottom of the supporting cylinder is fixedly connected to a support member. The present invention has the characteristics of being convenient for camera installation and helping the camera to shoot stably.

The air pressure is input into the Z-shaped channel 5 through the ventilation pipe 503, and the air pressure is input into the two groups of first pneumatic components through the Z-shaped channel 5. The air pressure is input into the drive channel 204 by the Z-shaped channel 5. The air pressure in the drive channel 204 controls the extension of the arc extension rod 203.

In this process, the elastic force of the elastic component is overcome, and the positioning block 309 is driven by the second slide 305 to slide out of the positioning groove 102 opened on the surface of the camera body 1.

[0076] It should be noted that the first control valve 501, the second control valve 502, the cylinder 8 and the camera body 1 used in this device are all existing technologies. The specific types of the first control valve 501, the second control valve 502, the cylinder 8 and the camera body 1 can be selected according to actual needs and will not be elaborated here.

[0077] The working principle and use process of the present invention: When the device is in use, the device is first installed in the range to be monitored in the power grid through the mounting bracket 801, and the cylinder 8 is connected to the power supply; when the cylinder 8 controls the operation of the first pneumatic component, the second control valve 502 controls the closure of the ventilation pipe 503 and the air distribution channel 504, and the first control valve 501 controls the ventilation pipe 503 to be connected with one group of the first pneumatic components, and the air pressure enters the linkage positioning component at the same time, and one group of the first pneumatic components and the two groups of linkage positioning components are in operation; the positioning blocks 309 in the two groups of linkage positioning components are disengaged from the positioning groove 102, and the arc-shaped extension rod 203 in the first pneumatic component pushes the first push plate 205 to move, and the first push plate 205 drives the camera body 1 to rotate through the track assembly, so that the monitoring angle of the camera body 1 is adjusted; after the adjustment is completed, the linkage positioning assembly It is connected to the camera body 1 to position the camera body 1, and continues to control the operation of the second control valve 502 to connect the ventilation pipe 503 with the air distribution channel 504, and the air pressure enters the second pneumatic component. The air pressure is input into the annular channel 701 through the ventilation pipe 503 and the air distribution channel 504, and the air pressure output through the air pressure channel 703 pushes the second push plate 601 to rotate in the outer ring frame 7, and the second push plate 601 drives the rotating block 6 to rotate, thereby driving the rotation of the arc block 2, and indirectly driving the camera body 1 to adjust the angle, so that the camera body 1 is adjusted to the range that needs to be monitored; by using this device, the cylinder 8 generates air pressure to control the angle adjustment of the camera body 1. Compared with the mechanism of the motor-driven reduction gear or worm gear, it has fewer parts and is not prone to the problem of reduced accuracy due to wear. There is no need for positioning, lubrication or replacement of parts, which effectively reduces maintenance costs.
