Description

Mechanical triggering type active fire extinguishing type power distribution cabinet Technical Field The invention relates to the technical field of power distribution cabinets, in particular to a mechanical triggering type active fire extinguishing type power distribution cabinet. Background The power distribution cabinet is a key device for distributing, controlling and protecting electric energy in a power system, and is internally provided with electric elements such as a breaker, a contactor, a relay, an instrument, various wiring terminals and the like, and along with the continuous growth of power load and the improvement of equipment integration level, the power distribution cabinet is easy to cause local high temperature and even open fire due to the problems of line aging, poor contact, overload or short circuit and the like in long-term high-load operation, so that obvious fire risks exist. In case of fire, the power distribution cabinet not only can rapidly spread to burn equipment in the cabinet, but also can cause interlocking power failure accidents to cause serious economic loss and safety threat, and the current common fire extinguishing modes of the power distribution cabinet mainly comprise a fixed gas fire extinguishing system, a dry powder automatic spraying device and the like, and the modes mainly adopt a fire extinguishing strategy with full coverage, however, for a large-scale power distribution cabinet with a complex internal structure and obvious partition, the fire extinguishing agent is fully sprayed, although the fire can be controlled, secondary damages such as pollution, corrosion or electrical short circuit and the like can be caused to normal components which do not fire, and the fire extinguishing system is just like a fly swing hammer, so that the sound equipment is damaged while the fire source is extinguished, and the reliability and the recovery efficiency of the system are reduced. In view of the foregoing problems, some attempts to solve the foregoing problems have been made in the prior art, for example, chinese patent publication No. CN117559239a proposes a power distribution cabinet with fire-extinguishing protection function, where the apparatus "includes a power distribution cabinet body, and further includes a fire-extinguishing protection device, a power device, an induction device, and a control device disposed in the power distribution cabinet body, where the induction device monitors a fire condition in the power distribution cabinet body and transmits a fire signal to the control device, and the control device controls the fire-extinguishing protection device and the power device to operate, so that the power device drives the fire-extinguishing protection device to move to a fire place for extinguishing a fire, and the power distribution cabinet with fire-extinguishing protection function includes a fire-extinguishing protection device and a power device disposed in the power distribution cabinet body, where both of the fire-extinguishing protection device and the power device are connected to the induction device, and the power device moves the fire-extinguishing protection device to the fire-extinguishing point after sensing the fire-extinguishing protection device, and the fire-extinguishing protection device performs a small-range centralized operation at the fire-extinguishing point, thereby reducing the influence on peripheral or other electrical components far from the fire-extinguishing point as far as possible. However, the scheme generally depends on electric power driving to realize a series of actions such as fire monitoring, device movement and fire extinguishing triggering, and in an actual fire scene, an internal circuit of a power distribution cabinet may be damaged, powered off or a control system fault occurs due to fire, so that a fire extinguishing system depending on electric power cannot be started normally or fails midway, and the problem of insufficient reliability exists. Disclosure of Invention The invention aims to provide a mechanical triggering type active fire extinguishing type power distribution cabinet, which can be independent of an active fire extinguishing system which is triggered by power and accurately acts, and can reliably and accurately complete fire extinguishing tasks when power is interrupted or the system is abnormal. In order to solve the technical problems, the invention adopts the following technical scheme: The mechanical triggering type active fire extinguishing type power distribution cabinet comprises a cabinet body, a mounting frame and a clamping rail, wherein the mounting frame comprises two vertical plates fixedly connected to the inner portion of the cabinet body and a plurality of transverse plates fixedly connected between the two vertical plates, the clamping rail is arranged on the mounting frame through screws and used for mounting electronic elements, the mechanical triggering type active fir
