Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric power engineering, in particular to an electric video lifting bracket with an adjusting mechanism. Background Art
[0002] In a substation, the layout of power equipment is complex and diverse, and different equipment needs to be monitored from different angles. For example, the transformer may need to be observed from multiple angles such as the top and the side to ensure its normal operating status. The power video lifting bracket with an adjustment mechanism can fully cover all key parts of the transformer through the lifting and angle adjustment functions, detect abnormal situations in time, and ensure normal power distribution and control.
[0003] Existing power video lifting brackets have some disadvantages. In order to ensure stability and load-bearing capacity, the bracket may be made of heavier materials, which makes it heavier. In some scenarios that require frequent movement or temporary installation, such as short-term inspections of different substations, heavier brackets are not convenient to carry and install quickly, which increases the labor intensity and working time of the staff. At the same time, although traditional lifting brackets have lifting and rotation adjustment functions, there may be situations where the adjustment range cannot fully meet all application scenarios. For example, in some special power facility layouts, video equipment is required to be able to achieve a larger angle of tilt or a higher lifting height, but the existing bracket adjustment range may not be able to achieve this. Secondly, when observing, the humid and dusty environment may cause the lens of the video equipment to be affected by dust, thereby affecting the observation effect and causing operation failure.
[0004] Therefore, there is a need for a device that can increase the flexibility of the lifting bracket, reduce the labor intensity and working hours of the staff, adopt a modular device, facilitate transportation and quick installation, regularly clean the lens of the video equipment, and reduce the impact of dust on the video surveillance effect.
