Automatic discharging device for fire sandbox

Abstract

The invention discloses an automatic discharging device for a fire sandbox, and belongs to the technical field of fire equipment. The automatic discharging device comprises the sandbox, electric cylinders, a sand blocking plate, a fixing rod, a distance sensing switch, a sensing metal sheet, heat-insulating fireproof plates and smoke induction switches; a feeding hole is formed in the upper side of the top of the sandbox, pulleys are symmetrically arranged on the two sides of the top of the sandbox, the lower ends of the electric cylinders are arranged on the upper sides of electric cylinder bases, the two sides of the sand blocking plate are hinged to shafts at the upper ends of the electric cylinders, the fixing rod is fixedly arranged on one side of the sandbox, the distance sensing switch is arranged on the fixing rod, the sensing metal sheet is fixedly arranged on the upper edge side of the sand blocking plate and corresponds to the distance sensing switch in position in the vertical direction, the smoke induction switches are fixedly arranged on the side parts of the sandbox, and the heat-insulating fireproof plates are fixedly arranged at the bottom of the sandbox and located on the outer sides of the electric cylinders. The automatic discharging device is simple and reasonable in structure and capable of guaranteeing automatic detection of the fire, the automatic fire extinguishing function is achieved, the safety is high, and the reliability is good.

Description

technical field [0001] The invention relates to an automatic unloading device for a fire-fighting sandbox, belonging to the technical field of fire-fighting equipment. Background technique [0002] Electric fire protection work is a highly social work, which can only be done well with the strength of the whole society and the care, attention, support and participation of all members of the society. The social nature of fire-fighting tools; fire management should penetrate into all areas of human life and harvest, thus determining the social nature of fire-fighting work; fire safety management involves all walks of life, and even thousands of households, in production, work and life During the process, people have a slight omission in fire safety management, and they may cause a fire if they lose their minds, lose control, or make mistakes in production for a while, which determines the regularity of fire protection work; It is complicated, but it can be seen that the vast m...

Problems solved by technology

The fire-fighting sand in the prior art is generally placed in a sand pool. When a fire occurs, the sand is generally transferred to an open fire by manual means for fire extinguishing. This method of fire extinguishing is slow, inefficient and reliable. Poor performance, often unable to keep up with the development of the fire, easy to cause greater losses, and low safety
