Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of special operation fire-fighting equipment, in particular to a special vehicle for hot work operations. Background Art
[0002] At present, in oil, chemical and some other high-risk fire-prone places with inflammable and explosive substances, frequent hot work operations often lead to frequent fire accidents; the main reason is that such places are prone to volatilize inflammable and explosive gases, the risk during hot work operations is high, and the on-site fire protection force is poor, which is extremely likely to cause fire accidents; for example, when an aircraft enters the hangar for inspection or maintenance, it will carry a certain amount of combustible and flammable liquids, such as aviation fuel, hydraulic oil, lubricating oil, etc. During the inspection and maintenance process, operations with relatively high fire risks such as cutting, welding, cleaning, and painting will inevitably be carried out, which are likely to cause fires and bring immeasurable losses.
[0003] From various studies on extinguishing fires, the best time to extinguish a fire is at the initial stage of the fire. Therefore, it is particularly crucial to develop a fire-fighting equipment that can move quickly, is small, flexible and convenient, and has strong fire extinguishing ability, fire detection ability and its own explosion-proof function.
[0004] For example, in response to the fire hazards during aircraft inspection and maintenance, mobile foam fire extinguishing devices are set up at the aircraft parking points and maintenance areas in the hangar. At present, such fire extinguishing equipment is mainly divided into two categories, one is a foam fire truck, and the other is a small mobile foam trolley.
[0005] Whether it is a foam fire truck or a mobile foam vehicle, most of their proportioning systems still use old-fashioned pipeline proportioning mixers or metering injection proportioning devices. The mixing accuracy of the pipeline proportioning device fluctuates greatly under the influence of water pressure and has poor stability; for the metering injection proportioning device, due to the time interval between flow measurement and motor frequency conversion, the response time is too long, and phenomena such as unstable mixing ratio are likely to occur; moreover, both of them do not have a fire detection function (such as combustible gas detection, etc.), and cannot detect the operation hazards during hot work in time; Summary of the Utility Model
[0006] In view of the above problems, the utility model provides a special vehicle for hot work operations, aiming to solve the problem that equipment in high-risk places such as oil, chemical and some other inflammable and explosive substances is prone to fire hazards during hot work operations.

[0011] Further, a storage battery, an inverter, and a PLC controller are provided inside the electrical control cabinet. The storage battery is shared with the electric vehicle main body. The inverter converts the voltage of the storage battery into a voltage available for the electrical control cabinet, the water outlet control cabinet, and multiple fire detection mechanisms.

[0012] Further, the fire detection mechanism includes a plurality of boom fixing blocks. All of the plurality of boom fixing blocks are provided inside the structural support.
