Abstract

The invention relates to the technical field of fire fighting equipment, and particularly relates to a sand-throwing fire extinguishing truck and a control method thereof. The sand-throwing fire extinguishing truck comprises a throwing actuator, a throwing hydraulic control system, a feeding actuator, a detection device and a control device. The throwing hydraulic control system is connected withthe throwing actuator and controls the throwing actuator to throw materials. The feeding actuator provides materials for the throwing actuator. The detection device is used to detect the working parameters of the throwing hydraulic control system. The control device is used to regulate and control at least one of the feeding speed of the feeding actuator and the throwing speed of the throwing actuator according to the working parameters of the throwing hydraulic control system detected by the detection device. The sand-throwing fire extinguishing truck and a control method thereof regulates the feeding speed and / or the throwing speed according to the working parameters of the throwing system so that the material supply can be easily matched with the throwing demand and the risk of materialblockage can be reduced.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a sand-throwing extinguishing train and a control method thereof. Background technique [0002] In order to meet the special fire extinguishing needs of avoiding fire, foam, carbon dioxide, etc., the sand throwing extinguishing truck was developed to improve the fire extinguishing efficiency and reduce the risk of rescue. However, the research and development of the sand extinguishing train is still in the initial stage, and the current sand extinguishing train is prone to problems such as material blockage. Contents of the invention [0003] A technical problem to be solved by the present invention is to reduce the risk of material clogging of sand throwing trains. [0004] In order to solve the above technical problems, the first aspect of the present invention provides a sand throwing train, which includes: [0005] The spreading system, including the sprea...
