Excavation foundation safety protection device

Abstract

The invention discloses a digging and excavation foundation safety protection device, which includes a helmet, and an internal protection and connection device is arranged inside the helmet, wherein a control box, a searchlight, a multi-way valve and a fan are installed above the helmet, and a transparent arc is installed under the front of the helmet. The baffle, the curved baffle is provided with a plurality of vertical chutes, the chute is provided with support rods, the ends of the same side of the plurality of support rods are all fixed on the inner wall of the helmet, and the ends of the other side are fixed to each other. The damper is installed, and the arc-shaped baffle is arranged between the damper and the inner wall of the helmet; the multi-way valve includes an air inlet, an oxygen inlet and an air outlet, and a filter is arranged on the air inlet; a fan is fixedly installed on the lower edge of the rear side of the helmet, and the fan A multi-way valve is installed above, and the air outlet of the multi-way valve communicates with the damper through the air duct. It can solve the danger of lack of oxygen, inhalation of foreign particles and harmful gases when the construction personnel dig deep foundations, thus providing construction personnel with more ways and more comprehensive safety protection.

Description

technical field [0001] The invention relates to a safety protective helmet, which belongs to a safety auxiliary tool for excavating foundation construction, and in particular to a safety protection tool for excavating and excavating foundations. Background technique [0002] At present, in the electric power industry, for the sake of convenience and the needs of the situation, some equipment installations need to be constructed using excavated foundation methods, such as power towers, cable laying, etc. In the process of excavation and excavation, construction workers mainly wear safety protective gear such as safety helmets or helmets, and the safety protection measures are single. The danger of gas, and the personnel above the ground cannot grasp the underground construction situation in time, and provide effective management and assistance, which brings great safety hazards to the construction personnel; Face and respiratory health are affected, because the light and air...
