The utility model provides the safety helmet capable of detecting the sulfur hexafluoride gas and alarming for the operation of transmission lines and maintainers, and the safety helmet is simple in structure and convenient to use.

Description

A safety helmet with detectable sulfur hexafluoride gas

technical field

The utility model relates to a safety helmet, in particular to a safety helmet used in the maintenance of power transmission lines.

Background technique

At present, the safety protection brought by hard hats to workers has been recognized by everyone, and there are corresponding clear wearing regulations in high-risk industries. Sulfur hexafluoride insulated combined electrical equipment (GIS) has been widely used on site. After the electrical equipment is put into operation, this gas will pose a great threat to the health and life safety of the staff and the operation and maintenance personnel of the GIS station. However, the current sulfur hexafluoride detection device has the disadvantages of being bulky and extremely inconvenient to carry. The operating personnel in the station are generally unwilling to carry such a bulky sulfur hexafluoride detection device during normal inspections. Therefore, there is an urgent need to develop a simple and convenient sulfur hexafluoride detection device on site.

Contents of the invention

The utility model provides a safety helmet with a detectable sulfur hexafluoride gas, which solves the problems of bulkiness and inconvenient carrying existing in the existing sulfur hexafluoride detection device.

The utility model solves the above technical problems through the following technical solutions:

A safety helmet with detectable sulfur hexafluoride gas, comprising a safety helmet cap body, a single-chip microcomputer connected to a battery is arranged in the safety helmet cap body, a sulfur hexafluoride gas sensor is electrically connected to the single-chip microcomputer, and the single-chip microcomputer A small buzzer is connected.

The battery, the single-chip microcomputer, the small buzzer and the sulfur hexafluoride gas sensor are all arranged on a printed circuit board.

The utility model provides a safety helmet capable of detecting sulfur hexafluoride and giving an alarm for the operation and maintenance personnel of the transmission line, which has a simple structure and is convenient to use.

Detailed ways

A safety helmet with a detectable sulfur hexafluoride gas, comprising a safety helmet body 1, a single-chip microcomputer 4 connected to a battery 2 is arranged in the safety helmet body 1, a sulfur hexafluoride gas sensor 3 and the single-chip microcomputer 4 are electrically connected, and the single-chip microcomputer 4 is connected with a small buzzer 5.

The battery 2, the single-chip microcomputer 4, the small buzzer 5 and the sulfur hexafluoride gas sensor 3 are all arranged on a printed circuit board.

Inside the safety helmet, a set of miniature gas detection circuit and a small buzzer 5 are arranged in the space between the support head net and the cap shell. The gas detection circuit is powered by the battery 2 installed on the safety helmet, hexafluoro The sulfur hexafluoride gas sensor 3 detects the content of sulfur hexafluoride in the air around the helmet, and reports it to the single-chip microcomputer equipped with peripheral circuits 4 to make a logical judgment through the signal comparison circuit, and finally when the sulfur hexafluoride content in the air reaches the set value When the concentration is higher, the small buzzer 5 sends an alarm.
