Description
Technical Field
The utility model relates to a technical field that emergency rescue was equipped, especially a protective cap that improves the ignition success rate of electroless cutting knife.
Background
Emergency rescue equipment and anti-terrorism department suddenly-operated equipment are two newer door types in the fire-fighting equipment, wherein break and tear the equipment open and developed through a period of time, a batch of novel function, reliable quality product have appeared, can realize the break and tear the equipment open of industrial production and large-scale equipment at present, mainly have following several types: manual break-in tools, electric break-in tools, motorized break-in tools, hydraulic break-in tools.
The power breaking and dismantling equipment has different weights and advantages, but has common limitation, namely high dependence on energy and equipment. The use of such equipment often requires heavy equipment and energy supplies, limiting its use in complex environments (e.g., open field, high altitude, underground) and emergency situations (large equipment is difficult to reach in time).
To overcome the above problems, the patent electroless cutting knife-201710670650.0 discloses a portable cutting device that does not require an external power supply for use. The equipment uses chemical energy to generate high temperature, and the high temperature is used for melting the barrier. The equipment comprises a medicine cylinder and a handle, wherein the medicine cylinder is a working part, and the handle is a control part. The outer wall of the cartridge will gradually melt and become shorter as the combustion progresses.
The patent relates to an electroless cutting knife-201710670650.0, wherein the medicament in the medicament cartridge comprises an ignition medicament and a main medicament, and the main medicament with high ignition point is ignited by the heat provided by the combustible ignition medicament. The ignition agent is a high-gas-yield agent, a large amount of gas is generated after ignition, and flame is violently sprayed towards the outer direction of the medicine cylinder. Therefore, most of the heat generated by the ignition powder is diffused to the outside air along with the flame, and the main medicament can be effectively heated when only the ignition powder at the interface of the ignition powder and the main medicament is combusted. The energy utilization rate is low, and the phenomenon of failure of ignition under severe conditions (such as strong wind, rain and snow weather) sometimes occurs.
Based on the defect of above-mentioned technique, the utility model discloses want to provide a protective cap that improves the ignition success rate of electroless cutting knife.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a name.
The purpose of the utility model is realized through the following technical scheme: the utility model provides an improve protective cap of electroless cutting knife's ignition success rate, includes protective cap, EVA sleeve pipe and high temperature resistant potsherd, the protective cap is the cylinder that has the air vent for opening on four sides, the air vent is used for shunting the flame that the part ignites the medicine and produces, EVA sleeve pipe outside and protective cap inner wall contour fit are connected through the viscose, the profile of high temperature resistant potsherd and protective cap top inner wall laminating is the circular arc curved surface, the high temperature resistant potsherd is located EVA sleeve pipe upper end.
Preferably, the protective cap is made of silica gel.
Preferably, the high-temperature-resistant ceramic chip and the protective cap are connected in an interference fit mode by the elasticity of silica gel.
Preferably, the protective cap is preferably cylindrical in shape.
The utility model has the advantages of it is following:
1. when in storage, the waterproof, moistureproof and shockproof effects are achieved;
2. when the ignition device is used, secondary heating is carried out through flame rebounded by the ceramic chip, the energy utilization efficiency of the ignition powder is increased, and the ignition success rate is improved;
