4results about How to "Effective fire extinguishing" patented technology

This utility model belongs to the technical field of fire-fighting equipment, and particularly relates to a multi-functional foam gun. It includes a first gun body, a primary foaming tube, a connector assembly, a secondary foaming tube, and a foam net holder. The primary foaming tube is installed at the front end of the first gun body, and the secondary foaming tube is installed at the front end of the primary foaming tube via the connector assembly. The foam net holder is installed at the outlet of the secondary foaming tube. The outer wall of the primary foaming tube is surrounded by several first suction holes, which are perpendicular to the central axis of the primary foaming tube. The outer wall of the secondary foaming tube is surrounded by several second suction holes, which are parallel to the central axis of the secondary foaming tube. This utility model uses a secondary negative pressure suction method combined with a foam net to achieve a final foaming ratio of 20 times for the foam extinguishing agent. In this state, the foam extinguishing agent has a low water content, low impact force, and short range, making it suitable for close-range coverage of fire sources, effectively extinguishing fires and preventing reignition.

This invention discloses an integrated fire-fighting device and method for thermal runaway, comprising an integrated fire-fighting body and a fire-fighting unit. The integrated fire-fighting body has a through hole and an aerosol generating chamber inside. The aerosol generating chamber contains a thermally sensitive wire, a fixed bracket, a connecting joint, a temperature-sensing element, a sealing cover, and aerosol. In this invention, the sealing cover is pressed tightly against the connecting joint by the temperature-sensing element, which can seal the fire-fighting medium in the fire-fighting medium channel. When the temperature-sensing wire reaches a set threshold, physical deformation occurs, triggering the release of aerosol, causing the aerosol to initially immerse the space where the integrated fire-fighting body is located. Then, the temperature-sensing element is driven to melt or rupture, connecting the fire-fighting medium channel with the aerosol generating chamber to release the fire-fighting medium for cooling. After the gas cooling agent is released, the pressure trigger valve detects the preset pressure and opens the spray nozzle to immerse the space again, achieving effective fire extinguishing, cooling, and decontamination even when not affected by strong magnetic fields.

This invention belongs to the field of electrical distribution box technology, and particularly relates to a theft-proof and secure intelligent electrical distribution box, comprising a distribution box, an anti-theft component, a heat dissipation component, a water-cooling component, and a fire extinguishing component. The distribution box is used to install electrical components. The anti-theft component is used to promptly sound an alarm when the distribution box is pried open. The heat dissipation component is used to dissipate heat from the internal space of the box and the electrical components. The water-cooling component uses circulating water to effectively cool the hot air discharged from the heat dissipation component inside the box and then recirculate it into the box to cool the electrical components. The fire extinguishing component is used to precisely extinguish fires on electrical components in the event of a fire. The anti-theft component in this invention can amplify the minute vibrations caused by prying or damage to the cabinet wall, effectively triggering the alarm and significantly improving alarm sensitivity. Furthermore, the anti-theft component is located inside the box and is not easily cracked, overcoming the shortcomings of traditional alarm systems with alarm lag.

This invention belongs to the field of mining vehicle technology and solves the problem of high fire risk in the engine compartment of mining vehicles in the prior art. This invention provides an automatic fire extinguishing system for mining vehicles, including a protective box and a fire extinguishing tank. The fire extinguishing tank is connected to a conduit, which is connected to a spray pipe. The spray pipe is equipped with a nozzle and a fire source detector. The protective box includes an outer box fixedly installed on the vehicle frame, and an inner box is set inside the outer box. The fire extinguishing tank is installed in the inner box. A primary vibration isolation component is set between the four inner side walls of the outer box and the four outer surfaces of the inner box. A gas injection component with an outlet aimed at the fire source detector is connected to the spray pipe. When the inner box shakes, the primary vibration isolation component absorbs the vibration force and pressurizes the gas injection component. When the gas pressure in the gas injection component reaches a threshold S, the gas injection component sprays high-pressure gas toward the fire source detector. This device can achieve automatic fire extinguishing of the engine compartment for a long time and effectively.
