Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection gas cabinet accessories, in particular to a side-expanded environmental protection gas cabinet. Background Art

[0002] Environmentally friendly gas cabinets are gas-filled electrical cabinets that use nitrogen or dry gas instead of the traditional sulfur hexafluoride gas that is harmful to the environment, and the airtightness of the cabinet is an important factor in the stability of the gas cabinet. Existing environmentally friendly gas cabinets are usually equipped with a barometer for workers to observe the air pressure status inside the gas cabinet. In order to distinguish whether the barometer pointer has changed in the later period, workers usually use a marker to draw a picture on the surface of the barometer to record the position of the barometer pointer, so that personnel can distinguish the position change of the pointer later. However, this method is inconvenient to use. When re-marking during later maintenance, workers need to erase the original mark, but usually due to the precipitation of time, the original mark left by the marker cannot be completely cleaned, causing inconvenience in use. There is a lack of a set of air pressure marking mechanisms that can be flexibly rotated and adjusted to be specially adapted for the use of environmentally friendly gas cabinets.

[0003] A Chinese patent discloses a side-expanded environmentally friendly gas cabinet (authorization announcement number CN 218334995 U). The patent technology has the advantages of simple structure, stable and reliable performance, small size, high safety, and good insulation performance. However, it does not have a set of air pressure marking mechanisms that can be flexibly rotated and adjusted to specifically adapt to the environmentally friendly gas cabinet, and it is not convenient to carry and move the gas cabinet.

[0004] Therefore, those skilled in the art provide a side-expanded environmentally friendly gas cabinet to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a side-expanded environmentally friendly gas cabinet, including a gas cabinet, wherein fixed columns are arranged at the four corners of the bottom of the gas cabinet, and a fixed frame is arranged at the bottom of the four corners of the lower end of the gas cabinet on one side of the fixed column, a groove body is opened inside the fixed frame, and a motor is arranged inside the groove body, the lower end of the motor is connected to a screw rod, and a slider is threadedly connected to the screw rod, a fixed block is fixed to one side of the slider, and a universal wheel is arranged at the lower end of the fixed block, two markers are fixed on the front side of the gas cabinet, and an annular base is arranged corresponding to the lower side of the marker, and a pressing sleeve is arranged inside the annular base and the marker, and a directional arrow is fixed on the pressing sleeve.

[0006] Preferably: the lower end of the fixed column is connected to an anti-slip pad, a controller is fixed to the outer bottom of the gas cabinet, a rotating column is fixed to the outer side of the gas cabinet, the right side of the rotating column is connected to the cabinet door, a supporting column is fixed to the top of the gas cabinet, and the upper end of the supporting column is connected to a left inclined plate, so as to facilitate rain protection operation of the gas cabinet.

[0007] Preferably: a right inclined plate is fixedly provided on the right side of the left inclined plate, the two markers are arranged symmetrically in number, a clamping ring is fixed at the bottom of the marker, a clamping groove is provided inside the annular base, and the clamping groove and the clamping ring are clamped and connected to each other.

[0008] Technical effects and advantages of the utility model:

[0009] 1. The utility model is connected to each other by the clamping ring and the clamping groove, so that after the compression sleeve is clamped to the annular base, the compression sleeve is limited, so that the pointing arrow keeps pointing to the position of the pressure gauge pointer for continuous marking. Therefore, in the later use of the environmental protection gas cabinet, the inspection personnel can understand the air pressure state inside the environmental protection gas cabinet by observing the gap between the pointing arrow and the pointer of the pressure gauge, so that the operating personnel can timely maintain and repair the environmental protection gas cabinet with air tightness problems. It is suitable for use in environmental protection gas cabinets with high requirements for gas air tightness.

[0010] 2. A motor is set to drive the screw to rotate clockwise, and at the same time drive the slider on the screw to move. The slider drives the universal wheel to move downward. The height of the universal wheel is higher than the height of the fixed column and the anti-slip pad. The four universal wheels realize the movement and transportation of the gas cabinet, which is practical. BRIEF DESCRIPTION OF THE DRAWINGS
