Description

Portable quick attack big gun Technical Field The utility model relates to the technical field of fire-fighting equipment, in particular to a movable quick attack gun. Background The fast attack gun is one kind of portable high pressure jetting device in fire-fighting equipment, and consists of gun body, support, rotating interface and high pressure water hose, and may be used in fast deployment and jetting of great amount of water or foam fire extinguishing agent. The fire extinguishing device is characterized by long range, large flow and flexible control, is suitable for complex scenes such as oil fires, chemical fires or high-rise building fires, can help firefighters to press fire outside a safe distance, is particularly suitable for rapid assault fire extinguishing in an initial stage or a narrow area of a fire scene, and effectively improves the fire extinguishing efficiency and reduces personnel risks. At present, the existing quick attack gun is single in mode, and the range and flow parameters are fixed, so that equipment or manual adjustment parts are required to be manually replaced when different fires (such as oil fires need to be covered by foam, solid fires need to be high-pressure water columns and long-distance needs to be high in range) are faced, the operation is tedious, the time is consumed, and the fire extinguishing opportunity is easily delayed. Disclosure of utility model The application discloses a movable quick attack gun, which aims to solve the technical problem of complex spray mode of switching the quick attack gun in the related technology. In order to solve the problems, the utility model adopts the following technical scheme: a mobile quick attack gun, comprising: the gun comprises a gun body, a sleeve and a sleeve, wherein the sleeve is arranged at one end of the gun body and can move along the axial direction of the gun body; One end of the shaft sleeve extends to the outside of the gun body, forms a second gap with the sleeve, and changes the length of the second gap along the axial direction of the sleeve along with the movement of the shaft sleeve; The driving piece is arranged on the gun body and connected with the sleeve and used for driving the sleeve to move. In some aspects, the shell has a flared section with a progressively larger inner diameter, and a first gap is formed between the sleeve and the flared section. In some schemes, the outer wall of the gun body is provided with a spiral groove, the shaft sleeve is embedded in the spiral groove, and the shaft sleeve moves along the axial direction of the gun body along with the rotation of the shaft sleeve. In some aspects, the outer wall of the sleeve is sleeved with a rubber sleeve. In some schemes, the mobile quick attack gun further comprises a locking part, wherein the locking part is arranged on the rubber sleeve and used for limiting the rotation of the shaft sleeve. In some schemes, the driving piece comprises a screw rod, one end of the screw rod is connected with the gun body through a bracket, and the other end of the screw rod is connected with the sleeve in a matched manner. The technical scheme adopted by the utility model can achieve the following beneficial effects: According to the movable quick-attack gun, when the gun body is in a working state, the water source is connected with the gun body, the water flowing through the gun body is sprayed outwards through the first gap, and the outlet cross section area of the first gap can be quickly adjusted under the condition that parts are not replaced through the design that the sleeve moves along the gun body, so that the flow rate and the spraying pressure of the fire extinguishing agent are accurately controlled. The second gap length adjustable design that axle sleeve and sleeve formed, through axial displacement axle sleeve change the clearance along telescopic extension, realized the quick switch-over of water smoke and water column mode, when second gap shortened, because of turbulent effect dispersion becomes fine water smoke after the rivers received the extrusion, is applicable to the scene of a fire cooling, suppresses the afterburning and reduces the smoke and dust diffusion, and when second gap is prolonged, the water flow path is smooth concentrated, forms high-pressure water column mode, can strike remote fire or pierce through high temperature region accurately. The structure linkage mechanism does not need an additional switching device, can flexibly adapt to the fire extinguishing scene requirement only through dynamic adjustment of gaps, and has the coverage range and the penetrating power, thereby remarkably improving tactical diversity and operation convenience.
