Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically a video monitoring device for substations. Background Technology

[0002] Surveillance is one of the most widely used systems in security systems. Currently, handheld video communication devices are the most suitable construction site monitoring systems on the market. Video surveillance is now the mainstream. From the earliest analog surveillance to the popular digital surveillance of a few years ago, and now to the emerging network video surveillance, tremendous changes have taken place. With IP technology gradually unifying the world, it is necessary to re-examine the development history of video surveillance systems. From a technical perspective, the development of video surveillance systems can be divided into the first generation of analog video surveillance systems, the second generation of digital video surveillance systems based on "PC + multimedia card", and the third generation of video surveillance systems based entirely on IP networks.

[0003] In substations, the height and location of different equipment vary greatly. Transformers are usually large and installed at high positions, while switchgear and other equipment are relatively low. Most existing substation video surveillance devices adopt a fixed installation method, and the height of the cameras is difficult to adjust flexibly according to actual monitoring needs. This may lead to problems such as some areas not being captured or blind spots during monitoring. At the same time, regular maintenance is required, and it is not convenient to lower the cameras in a timely manner. Therefore, this utility model provides a video surveillance device for substations. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a video monitoring device for substations. Compared with the prior art, it has the following advantages:

[0015] Firstly, the transmission belt in this invention operates via a drive shaft and a first and second transmission wheel on the shaft. A connecting rod on the transmission belt drives the mounting base to move up and down. The mounting base drives a positioning slide rod to slide within a ring groove, while the positioning slide rod slides on a positioning rail, ensuring the stability of the mounting base's movement. This allows for adjustment of the camera's height. By flexibly adjusting the camera's height, the camera can be adjusted to a suitable height according to actual monitoring needs, given the varying heights and positions of different devices in a substation. This results in a clearer and more comprehensive monitoring image, improving monitoring effectiveness. Furthermore, the camera can be lowered directly for easier maintenance.

[0016] Secondly, when installing the camera body, the mounting block is first inserted into the mounting groove, allowing the positioning rod to engage in the groove for initial positioning. Then, an external tool, such as a wrench, is used to rotate the screw. The rotation of the screw causes the movable block to move along the screw's axial direction. This movement of the movable block drives the movable rod, which in turn pushes the opening and closing block to move. The opening and closing block then causes the clamping plate to slide towards the mounting block until the locking rod is fully inserted into the locking groove, securely locking the mounting block in the mounting base. This completes the installation of the camera body. For disassembly, the screw is rotated in the opposite direction to move the clamping plate away from the mounting block, disengaging the locking rod from the locking groove. The camera body can then be easily removed. The screw drives the clamping plate for quick locking and unlocking, eliminating the need for complex tools and facilitating camera replacement and maintenance. The engaging connection between the positioning rod and the positioning groove ensures precise positioning and installation of the camera body. Attached Figure Description

The transmission belt 207 is configured to transmit power through the drive shaft 205 and the first transmission wheel 206 and the second transmission wheel 301 on the transmission shaft 3. The connecting rod 302 on the transmission belt 207 drives the mounting base 303 to move up and down. The mounting base 303 drives the positioning slide rod 403 to slide in the annular groove 4. At the same time, the positioning slide rod 403 slides on the positioning slide rail 402 to ensure the stability of the movement of the mounting base 303, thereby realizing the adjustment of the height of the camera body 501.

Then, the drive motor 204 starts, and the drive shaft 205 drives the first transmission wheel 206 to rotate. The transmission belt 207 is driven by the first transmission wheel 206 and the second transmission wheel 301. The connecting rod 302 on the transmission belt 207 drives the mounting base 303 to move up and down. The mounting base 303 drives the positioning slide rod 403 to slide in the annular groove 4. At the same time, the positioning slide rod 403 slides on the positioning slide rail 402 to ensure the stable movement of the mounting base 303, thereby realizing the height adjustment of the camera body 501. If the camera body 501 needs to be disassembled, the screw 607 is rotated in the opposite direction to move the clamping plate 7 away from the mounting block 601. After the locking rod 701 disengages from the locking groove 604, the camera body 501 can be removed.
