[0001] The utility model relates to the technical field of overhaul of thermal power plants, in particular to a safety insulation protection device for overhaul of thermal power plants. Background Art

[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses coal, oil, and natural gas as fuel to produce electricity. There are many electrical equipment in a thermal power plant. In order to ensure the safe use of electrical equipment, the electrical equipment needs to be inspected and maintained. During the inspection and maintenance, insulation protection is required to improve safety.

[0003] According to the patent with application number 202211263947.2, a safety insulation protection device for maintenance of a thermal power plant is disclosed, including a handle, one end of the handle is connected to a connecting rod, the end position of the connecting rod is connected to an inspection head, the other end of the handle is connected to an indicator light, and the outer surface of the handle is provided with an upper insulating sleeve and a lower insulating sleeve, the top of the upper insulating sleeve is fixedly installed with an anti-drop handle, and the bottom of the upper insulating sleeve is fixedly installed with a locking column, the top of the lower insulating sleeve is provided with a locking groove matching the locking column, and the outer surface of the inspection head is connected with a limiting mechanism.

[0004] By adopting the above scheme, the insulation protection device of the thermal power plant can be limited when it is working, and the maintenance tool can be ensured to be accurately maintained, thereby improving the safety of the maintenance tool. However, after the upper insulating sleeve and the lower insulating sleeve are put on the handle, the above scheme only limits the upper insulating sleeve and the lower insulating sleeve through the connection between the card and the column and the card and the groove, and the connection stability is low. Therefore, when the user holds the anti-drop handle for inspection, the upper insulating sleeve and the lower insulating sleeve may fall off the handle. To this end, we provide a safety insulation protection device for maintenance of thermal power plants to solve the above problems. Utility Model Content
