Heliport safety protection screens

Abstract

The invention provides heliport safety protection screens which comprise a heliport body. The multiple protection screens are installed on the peripheral side of the heliport body. A first U-shaped steel channel, a fixing block, an oil inlet pipe and an oil return pipe are installed on the heliport body. A second U-shaped steel channel is formed in the side wall of each protection screen. A hydraulic oil cylinder is arranged between the first U-shaped steel channels and the second U-shaped steel channels and used for driving the protection screens to be lifted. One end of the oil inlet pipe and one end of the oil return pipe are connected with the hydraulic oil cylinder, and the other end of the oil inlet pipe and the other end of the oil return pipe are connected with a hydraulic control system used for controlling the protection screens to be lifted. The hydraulic control system drives the hydraulic oil cylinder to work through the oil inlet pipe to enable the protection screens to be in upright state, the hydraulic control system is closed, and the protection screens enable oil in the hydraulic oil cylinder to return into a hydraulic oil tank by means of self weight to be in the horizontal state. Lifting of the protection screens can be controlled remotely, automatic degree is high, the structure is firm, maintenance and installation are convenient, and the safety coefficient is high.

Description

technical field [0001] The invention relates to the technical field of protection nets, in particular to a safety protection net for a helipad. Background technique [0002] With the development of society, helicopters are used more and more widely, which creates more and more needs for elevated aprons in cities, and in this field, our country is still in the initial stage of development, generally in buildings or tall buildings An elevated apron is set on the top to solve the problem of parking and landing of helicopters. [0003] In the prior art, the protective net of the helipad is pulled out by cutting holes in the steel plate to form a net plate with diamond-shaped holes. There are differences in different technologies. When installing the protective net, workers need to work under the apron, which poses a great safety hazard. In addition, the existing safety net of the helipad has a single function and lacks a remote control lifting function, which is inconvenient to...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the helipad protective net is made of steel plate cut holes to form a mesh plate with diamond-shaped holes. Its own weight is relatively large, and it is time-consuming and labor-intensive to weld and fix it with the protective net frame. There are differences due to different technologies. When the protective net is installed, workers need to work under the apron, which poses a major safety hazard. In addition, the existing safety net of the helipad has a single function, lacks remote control lifting function, and is inconvenient to operate.
