Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of high voltage electrical apparatus, especially to a shell inner wall cleaning tool. BACKGROUND

[0002] Gas insulated metal enclosed transmission line (hereinafter referred to as GIL) is a new type of high voltage, large current power transmission equipment which adopts SF6 gas or other mixed gas as insulation medium, and the shell and the conductor are coaxially arranged. GIL adopts dust-free assembly, and most GIL discharge accidents are caused by foreign matters in the shell, thereby causing abnormal phenomena such as equipment flashover, insulation breakdown and conductor overheating. Therefore, the shell inner wall must be thoroughly cleaned after shell processing and before busbar assembly. Usually, the shell inner wall is first cleaned by high pressure, and then the shell inner wall is thoroughly cleaned to meet the dust-free requirement for assembly.

[0003] Currently, there are two common cleaning methods. One is to manually enter the shell interior for cleaning, and the other is to make a shell inner wall cleaning head. The two ends of the cleaning head are provided with hoisting bolts for connecting nylon ropes. The cleaning head is pulled from one end of the shell to the other end by manually pulling the nylon rope to clean the shell.

[0004] In actual use, it is found that both methods need manual cooperation. The first method requires manual entry into the shell inner wall. Not only is there a requirement for the diameter of the shell, but the manual cleaning method cannot thoroughly clean the shell inner wall. It may not meet the dust-free requirement for GIL busbar assembly. The second method has a relatively ideal cleaning effect, but it is very laborious and inefficient to manually pull the cleaning head. UTILITY MODEL CONTENTS

The connecting shaft 21 is designed to be detachable, which is convenient for the installation and dismounting of the sponge annular ring 25.

[0035] With reference to Figure 3 and Figure 4 The fixed part 23 and the connecting part 24 are both sleeved with the sponge annular ring 25. In the embodiment, two sponge annular rings 25 are respectively sleeved on the fixed part 23 and the connecting part 24, both sides of the sponge annular ring 25 are provided with support plates 26, support through holes for the connecting shaft 21 to pass through are formed in the support plates 26, and the support plates 26 are used to support the sponge annular ring 25, so that the sponge annular ring 25 can keep a state of being attached to the inner wall of the shell 1. The side of the support plate 26 which is away from the sponge annular ring 25 is also provided with a pressing plate 27, the pressing plate 27 is threadedly connected with the connecting shaft 21, the position of the pressing plate 27 on the connecting shaft 21 can be adjusted through the rotation of the pressing plate 27, so that the support plate 26 can be in a state of being tightly pressed against the sponge annular ring 25, and the stability of the sponge annular ring 25 installed on the connecting shaft 21 is improved. In the embodiment, the pressing plate 27 is made of aluminum.
