Description

Fire-fighting lance capable of preventing water pipe from falling off

Technical Field

The utility model discloses a belong to fire-fighting lance technical field, specifically be a fire-fighting lance that prevents that water pipe from droing.

Background

The first fire team in europe built in the 17 th century, germany started to use the fire pump earlier in the 15 th century. A picture stored at present is drawn on a machine, and a tube is fixed on the upper part of the machine, and the length of the tube is about 1 meter, and the tube is made of copper. From which pressurized water can be ejected. This is the most primitive form of fire-fighting lance and has been maintained through the 17 th century. At that time, the famous netherlands inventor john wanel conceived to separate such original water gun fixed to the water pump from the pump body. He was then using a leather hose to connect the two. Therefore, the water gun can move freely and can be guided to any place where a fire breaks out, and the real water gun for spraying water and extinguishing fire is born. This water gun format has been maintained through the 19 th century. It is known from the historical literature that such water guns are characterized by being very long, being made of copper and almost 2 meters long.

In the beginning of the 19 th century, the first water guns were connected to the pipe by a screw cap. At its end there is a so-called "lockbox", which, being fixed to the gun shaft, makes it possible to rotate the gun as a whole in order to adjust the throw of the gun.

The research and development history of water guns is quite long. Since the water press pump is used in the beginning of the 19 th century, the water gun is connected to the pump through a pipe without a valve. Thus, the pressure is transmitted directly by the piston. If the water gun is turned off, the water pump can be directly damaged. In addition, the diameter of the old water gun has not changed for a long time, because the diameter of the pipeline connecting the old water gun with the water pump has not changed.

In 1870, steam pumps were introduced and used for fire fighting. But then few fire departments in cities have access to such equipment. So that the water gun matched with the water gun is not much. However, these guns are all equipped with an 80mm bayonet "connection which allows the gun to be turned off by means of a lever. The emergence of fire-fighting vehicles brought revolutionary changes to the fire-fighting industry at the end of the 19 th century. Various water guns with different sizes are produced in succession. It was surprising that the classification of water guns at the time was determined according to the classification used to fight various types of building fires. By the 20 th century, the development of fire-fighting water guns has entered various specialized departments. The water guns available to firefighters have many modes of spraying, from direct spraying to scattered spraying and then to mist spraying. In the 30 s of the 20 th century, the axial water supply reel type water gun appeared for the first time. Particular mention is made here of the well-known "urinating" water guns. It has multiple models with the same shape and different sizes. Is quite popular in the Paris fire brigade. The device is basically used on the first-speed vehicle, and the effect is excellent.

In the 50 s of the 20 th century, the development of fire-fighting water guns was further refined. Research and development personnel of fire fighting equipment vigorously develop special water guns for various types of fires, such as automatic jet water guns, water guns dedicated to electrical fires, and water guns that jet foam.

The material of the fire-fighting lance is changed along with the development of science and technology. Ancient squirts were generally made of copper, including bronze and brass. Now, water guns have been developed that are made of light alloys, which are more convenient and easier to hold in the hand.

The fire-fighting lance can be commonly encountered in life, when the fire-fighting lance is used for discharging water, the pressure is huge, the risk that the water inlet pipe falls off is easily caused, when the water inlet pipe falls off, the installation is inconvenient, the time delay is delayed, the scene fire is changed instantly, before the water pipe is probably installed again, the fire can be collected once, the fire spread can cause huge disasters, and some people can possibly sacrifice the fire.
