Description

Technical Field

[0001] The utility model relates to the technical field of mobile fire-fighting water cannons, in particular to a mobile fire-fighting water cannon for firefighting. Background Art

[0002] Fire water monitor is a fire-fighting equipment that uses water as a medium to extinguish fires at a long distance. It consists of a fire monitor body and an on-site controller. When in use, it automatically sprays water in a direct current column or spray pattern according to the distance from the fire point, thereby extinguishing the fire while protecting personal and property safety.

[0003] For example, Chinese patent CN219539331U discloses a fire-fighting water cannon that is easy to move for firefighting. The support block and the supporting member are provided to drive the support block to contact with the ground, so as to prop up the wheels of the mobile vehicle. The mobile vehicle is supported by the contact between the support block and the ground, and then the support block is supported by the supporting member. Therefore, when the water cannon barrel is used, the structure of the mobile vehicle is stable and the rollover is reduced. The use is convenient. The screw rod is driven to rotate by the provided driving member, and then the screw sleeve can drive the support block to slide close to the ground under the restriction of the limit member, so as to support the mobile vehicle. After the fire is extinguished, the screw rod is rotated in the opposite direction to drive the screw sleeve to drive the support block away from the ground. The mobile vehicle can be moved away when the vehicle is re-supported with the ground. The operation is simple and quick.

[0004] Although this structure can support the mobile vehicle, the water cannon barrel has a large recoil when in use. When it rotates and sprays, the mobile vehicle needs to have a large supporting strength to ensure that the water cannon barrel sprays stably. Therefore, we propose a fire-fighting water cannon that can stably support the mobile vehicle and make the water cannon barrel spray more stably, thereby improving the stability of the mobile vehicle.
