Description

Auxiliary replacement device for suspension type fire extinguisher Technical Field The application relates to the technical field of auxiliary tools for electric power operation, in particular to an auxiliary replacement device for a suspended fire extinguisher. Background With the rapid development of society and economy, the requirements of various industries on the reliability and the continuity of power supply are increasingly improved, and a 10kV transformer room is used as a key node for power transmission and distribution, so that the stable operation of the 10kV transformer room is directly related to the safety of regional power supply. Currently, a 10kV transformer room is provided with a hanging fire extinguisher for fire-extinguishing rescue operation in emergency, when the hanging fire extinguisher is required to be replaced in time after reaching the service life or being damaged, the traditional replacement mode is required to rely on the specific time of the comprehensive power failure window period to conduct centralized treatment, but the traditional replacement mode can lead to the situation that the hanging fire extinguisher cannot be replaced in time to have great potential safety hazards, and the transformer room is brought with great fire hazards in load intensive periods such as the electricity utilization peak period in summer. Therefore, the operation mode of replacing the hanging fire extinguisher in power failure is adopted in more occasions in the industry. However, the power failure replacement operation faces multiple technical problems that safety distances between operators and the electrified body and between operators and the grounding body are strictly ensured to avoid safety accidents such as electric shock, complex environmental differences of different power distribution rooms are solved, explosion risks of overdue or damaged fire extinguishers are avoided, safety risks are high, operation is complicated, difficulty is high, and replacement efficiency is affected. Disclosure of Invention Based on this, it is high to have the security risk to have a power failure to change the operation to the conventional art, and complex operation is inconvenient, changes the inefficiency problem, provides a supplementary change device of suspension type fire extinguisher. The application provides an auxiliary replacement device for a suspension type fire extinguisher, which comprises the following components: the insulation shielding mechanism is used for being arranged between the transformer and the replacement operation area; The fixed clamping mechanism is used for clamping and fixing the hanging chain of the hanging fire extinguisher, and a movable pull rope is arranged on the fixed clamping mechanism; A mounting mechanism and a hook, the mounting mechanism being detachably connected to the hook for mounting the hook to a ring of a hanging fire extinguisher, the hook being connected to one end of the pull cord, and The protection mechanism is provided with a protection cavity, and the protection cavity is used for accommodating a fire extinguisher main body of the hanging fire extinguisher. The auxiliary replacing device is applied to a working scene of disassembling and replacing a hanging fire extinguisher in a 10kV transformer room, when the auxiliary replacing device is used, firstly, an insulating shielding mechanism is installed between a transformer and a replacing operation area to separate the transformer from the replacing operation area where an operator is located, so that the operator can keep a safe distance from a live body and a grounding body and eliminate electric shock risks, then, a fixed clamping mechanism is installed at a hanging chain of the hanging fire extinguisher in a clamping mode to enable the fixed clamping mechanism to serve as a bearing and operation foundation, on the basis, a hook is hooked with a circular ring of the hanging fire extinguisher through an operation installation mechanism, then the installation mechanism is separated from the hook, then, a protection mechanism is operated to approach the hanging fire extinguisher, so that a fire extinguisher main body is installed into a protection cavity, therefore, the operator pulls a pull rope to lift the fire extinguisher main body upwards, the fire extinguisher main body is separated from the original hanging chain hook, then, whether the pull rope is gradually pulled or not, the hanging fire extinguisher main body can be slowly pulled down to finish disassembling operation, and the protection mechanism provides a whole process of protection for the fire extinguisher main body, and the protection device can well cope with sudden falling or explosion risks. Therefore, the auxiliary replacement device for the suspended fire extinguisher can strictly ensure the safety distance between an operator and the electrified body as well as between the operator and the grounding body so as to avoid saf
