Adjustable observation window

Abstract

The invention relates to an adjustable observation window, and belongs to the technical field of equipment. The adjustable observation window comprises a double-layer housing of the observation window, synthetic glass fixed in the double-layer housing, a right-angled prism that can rotate around the axis, and a right-angled prism adjustable support; and the right-angled prism is fixed on the right-angled prism adjustable support, and the right-angled prism adjustable support is arranged on the double-layer housing of the observation window. An operator can observe a front bottom object image in the orthophoria angle of the eyes through the adjustable observation window, the maximal visual scope is 3 times that of an original equipment observation window, and blind observation areas in thebottom of equipment are reduced greatly. The plastic housing not difficulty in perforating can be easily mounted on the original observation window, so that the cost is reduced and power-off time is shortened. The adjustable observation window in of embedded installation design, and during installation, rainwater can be avoided by only using glass cement for sealing a slit between a glass and a cabinet door.

Description

technical field [0001] The present invention relates to the technical field of equipment, and more particularly, to an adjustable observation window. Background technique [0002] 35kV-500kV substation outdoor arc suppressing coil cabinets and DC isolation device huts are prone to corrosion at the bottom of the cabinets and poor blocking of small animals due to the increase in service life and the influence of the southern climate. The original equipment observation window design is unreasonable, the viewing range is only 10°-15° horizontal angle of view, and the height of the equipment in the cabinet is mostly lower than this horizontal angle of view, making it difficult for operators to observe the internal equipment and the bottom of the cabinet through the observation window. In the case of small animals blocking, there is a large blind area, which increases the probability of accidents caused by closed equipment due to potential safety hazards. At present, this type of...

[0002] 35kV-500kV substation outdoor arc suppressing coil cabinet and DC isolation device hut due to the increase in service life and the influence of the southern climate, the bottom of the cabinet is prone to rust and poor blocking of small animals

The original equipment observation window design is unreasonable, the viewing range is only 10°-15° horizontal angle of view, and the height of the equipment in the cabinet is mostly lower than this horizontal angle of view, making it difficult for operators to observe the internal equipment and the bottom of the cabinet through the observation window. In the case of small animals blocking, there is a large blind area, which increases the probability of accidents caused by closed equipment due to safety hazards

At present, this type of observation window commonly used in substations cannot effectively observe the operation of the equipment in the cabinet and the blockage of the cabinet. There are blind spots, which prevent the operators from discovering equipment defects in time, and there are great potential safety hazards for the equipment.

[0003] Generally speaking, there is a blind area between the outdoor arc-suppression coil cabinet of the 35kV-500kV substation and the observation window of the DC isolation device cabin, and it is impossible to observe the overall operation of the equipment inside the cabinet through the observation window, especially the corrosion of the edge of the cabinet door and the bottom plate and the corrosion of the bottom. The situation of preventing small animals from blocking increases the probability of accidents caused by outdoor closed equipment due to potential safety hazards
