Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and more specifically to a non-stop visual moisture-proof spraying device for power distribution cabinets. Background Art

[0002] Regarding the moisture and condensation problems of indoor electrical equipment such as distribution cabinets, moisture often invades the equipment cabinet from the holes at the bottom of the cabinet through the cable trench. However, due to the narrow space and dense cables in the cable trench at the bottom of the cabinet, people cannot enter, resulting in no effective measures to seal the bottom of the cabinet to prevent moisture. In addition, it is difficult to shut down the power supply for equipment that is energized during operation. The interior of the equipment is sealed with silicone rubber self-leveling material, and the power must be shut down for internal construction of the distribution equipment, which increases the power outage time of the city's power supply and reduces the reliability of power supply. It is generally difficult to implement.

[0003] When the inside of the cable trench sidewall hole is not a regular straight line shape, and there are bends, branches or other irregular curved parts, the flexible connection state of the drag chain can play a good role. For example, in some old cable trench systems, due to long-term geological changes or differences in the original construction, the sidewall hole may be partially bent. The drag chain can bend with the bending of the sidewall hole through a chain-like structure, and move through a complex path like a flexible "snake"; in the newly built or standardized cable trench sidewall hole, there are many parts that are long and straight and the sidewalls are relatively regular. At this time, it is very suitable for the drag chain to maintain a horizontal straight state.

[0004] In existing distribution stations, moisture-proof treatment is mostly carried out manually by spraying the cable trench. During the operation, the narrow space and dense cables in the cable trench at the bottom of the cabinet are inaccessible to humans, resulting in no effective measures to seal the bottom of the cabinet for moisture-proofing. In addition, it is often difficult to operate the equipment during live operation. In view of this, we propose a non-stop visual moisture-proof spray device for distribution cabinets.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention utilizes a towing drive mechanism in a mechanized manner to cause the drag chain assembly to extend outward, and cooperates with an infrared monitoring probe to perform real-time visual monitoring. This method is based on the miniaturized setting of the drag chain assembly, and the operating space required is small compared to traditional medium and large machinery and manual labor.

[0017] 2. The present invention arranges guide adapter grooves at both ends of the arc, and then utilizes the spiral-wound arrangement of the accommodation groove to accommodate as many winding and drag chain components as possible.

[0018] 3. The present invention uses a setting of relative left and right sliding of the limit block to enable the central axis basic limit protrusion to be plugged in and matched with the two adjacent gear connecting seats to form a basic fastening effect and a conventional rotational connection state. At the same time, the support is provided by reinforcing the load-bearing protrusion to reduce the stress deformation caused by excessive outward extension of the winding drag chain assembly, effectively improving the stability of the fastening state of the two adjacent gear connecting seats. At the same time, the fastening state is used to achieve the rigid connection of the external part of the drag chain assembly protruding from the mechanical operating frame, which can be effectively used for visual moisture-proof paint spraying of horizontal and vertical cable trenches. At the same time, the central axis basic limit protrusion is not plugged in and matched with the two adjacent gear connecting seats, so that the drag chain assembly can be flexibly changed at a certain angle, which can be used to adapt to the visual moisture-proof paint spraying of cable trenches with bifurcated angles.
