Embodiment Construction

[0023] In Example 1 of the present invention, the cutting tool 1 is a "universal tool" made of 2 diamond blades and 2 alloy blades spaced apart and combined with a size of 10*10*5mm. The tool barrel 2 is the same diameter barrel, with a diameter of 50mm and a length of 350mm, and 30 drainage holes 10 with a diameter of 10mm. The front handle 3 and the rear handle 4 are used to grasp the water gun, so that they can be held tightly and feel good. The general length, width and thickness are 100*30*26mm. The front end cover 5 and the rear end cover 6 are mainly used for protection, positioning and sealing, and can be connected and fixed on the shell 12 with a ferrule or a screw thread. The impeller 7 is driven by water to generate rotational force. In the embodiment, 6 pieces are used, and the length, width and thickness are 320*80*2mm. They are welded on the main cylinder 8 after arc spinning. Bearing 9 is to fix main body cylindrical body 8 and reduce frictional force, with fro...

Abstract

The invention provides a fire-fighting lance which is capable of passing through wall barriers under the conditions of pressure and flow rate of fire-fighting water and is high in water yield. The fire-fighting lance can reach the technical performance of a common fire-fighting lance without being additionally provided with power and equipment and is capable of passing through the barriers such as walls; when a hole in which the lance can enter is formed through cutting in the wall, the lance can spray water into the barriers through the hole; and the fire-fighting lance is generally used in a relative airtight environment and can achieve the purpose of rapid fire fighting by cooling through evaporation and diffusion of water and accelerating the reduction of oxygen content in a burning area.

Description

Technical field [0001] The invention relates to a fire-fighting water gun capable of passing through obstacles in time during fire-fighting, and belongs to the technical field of fire-fighting. Background technique [0002] Most of the current fire extinguishing water guns only pursue the form products of the distance of spraying water, the flow rate and the diversity of water column. Recently, in CCTV's "I Love Invention" column, there is an extended application of high-pressure liquid pump pressurized water and a portable water jet mixed with emery abrasive, and the high-pressure water mixed with emery abrasive is used to extinguish fire through obstacles such as walls The fire water gun has been well received by everyone. Its caliber is 1mm and its working pressure is > 30Mpa. But sparked the inspiration of the present invention. Contents of the invention [0003] In order to overcome the disadvantages of the existing fire extinguishing water guns that pass through...
