Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to an anti-explosion and demolition water gun. Background Art

[0002] Usually, when a fire first breaks out, the heat, smoke and gas released by the burning materials in the fire gradually increase the air temperature in the fire, which leads to an increase in the combustion rate, generating more heat energy and thick smoke. At this stage, if the combustion rate exceeds the rate at which fresh air is added to the fire, the combustion products will continue to accumulate and the flame will not spread normally. When the flame cannot spread normally, the volatile gases in the combustibles will continue to volatilize on a large scale under the action of the flame, and the heat generated by the combustion will continue to accumulate, causing the temperature of the fire to continue to rise. When the temperature reaches a certain level, the pyrolysis reaction rate of the combustibles will increase sharply, generating a large amount of combustible gas and thick smoke. At this time, if a large amount of combustion aid is injected into this range, large-scale combustion will occur instantly. As the combustion area expands rapidly, the heat generated by the combustion causes the gas volume to expand rapidly, forming a strong airflow of high temperature and high pressure, thereby generating huge destructive power and then forming a flashover.

[0003] The existing demolition water gun is just a simple sharp object that can only penetrate and extinguish relatively soft material piles, but cannot quickly demolish walls, wood, metal, and other hard materials. The existing equipment to completely demolish such hard materials is relatively small and bulky. Most of them are still used to break doors with axes, iron spikes, and other equipment. The low degree of automation and bulkiness of the equipment seriously affect the firefighters' rapid operation to complete the demolition and firefighting operations. In the face of dangerous places with flashover and backdraft, it is not possible to demolish and discharge water to cool down at the same time, and quickly lower the indoor temperature, which is extremely likely to cause fire flashover and threaten the safety of firefighters.

[0023] Furthermore, it also includes a fixing plate, the driving member is mounted on the fixing plate, the fixing plate is connected to the top of the connecting seat, and the output end of the driving member passes through the fixing plate.

[0024] In the above scheme, the fixing plate provides a stable supporting structure, so that the driving component remains stationary during operation and prevents displacement due to vibration or external force, thereby ensuring the stable operation of the driving assembly. The driving assembly is connected to the connecting seat through the fixing plate, which can facilitate operation by firefighters.

[0025] The utility model of an anti-explosion and demolition water gun has the following beneficial effects:
