Water-cooling heat insulation safety helmet for electric power overhaul

Abstract

The invention relates to a safety helmet, in particular to a water-cooling heat insulation safety helmet for electric power overhaul. The water-cooling heat insulation safety helmet comprises a safety helmet shell, a safety helmet liner, a safety belt and a safety helmet lower jaw strap. The safety helmet liner comprises a bottom plate and a push-pull plate, the bottom plate comprises a supporting shell and a cooling tube, the push-pull plate comprises a push plate and a push-pull rod, sliders with inverted trapezoidal sections are arranged on two sides of the upper end face of the push plate, the push-pull rod is arranged in the middle of the tail end of the lower end face of the push plate, the supporting shell is matched with the inside of the safety helmet shell, and a groove matched with the cooling tube is formed in the lower end face of the supporting shell. The cooling tube is clamped into the groove in the lower surface of the supporting shell, and the push-pull plate is slidably connected with the supporting shell through the sliders. The push-pull rod is moved with a hand, the push-pull plate is driven to move, and the lower half portion of the cooling tube is exposed at the moment. After a user wears the safety helmet, the lower half portion of the cooling tube contacts with the head of the user to function in cooling. The safety helmet has the advantages that heat dissipation can be effectively improved, and heat insulation and heat dissipation functions can be switched when required.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a water-cooled heat preservation type safety helmet used for electric power maintenance. Background technique [0002] Existing safety helmets generally only consider the problem of safety, and the inner liner is fixed inside the helmet shell in various ways, such as the Chinese patent announcement number: CN 204888858 U, which was disclosed on December 23, 2015, in a winter and summer Helmet: Heating wire is introduced inside the helmet, and holes are drilled on the cap shell. This utility model has some disadvantages such as heating by the heating wire is dangerous and cannot be adjusted, and the cooling effect of perforated ventilation is not good. Contents of the invention [0003] The present invention mainly aims at the above-mentioned problems, and provides a water-cooled heat-retaining safety helmet for power maintenance, which can effectively improve heat dissipation and switch betwe...
