Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire and gas early warning technology, specifically to a fire and gas video early warning system for well workover rigs. Background Technology
[0002] The well workover rig fire and gas early warning control system is a monitoring system capable of detecting and alarming fires and gas leaks. When a fire or gas leak occurs at the well site, the system can issue an alarm signal and activate safety facilities such as broadcast systems and status lights. The dedicated fire and gas control system for well workover rigs can direct the automatic fire suppression system to extinguish fires in the electrical control room, can issue a signal to shut down the main power supply to the well workover rig, and can control the fire and gas control panel on the platform for display and processing via hard and soft wiring. It is an essential safety monitoring device for well workover rigs.
[0003] Currently, when a workover rig is in operation, operators are generally on the rig's drilling deck. When a fire occurs in a certain area of the workover rig and the rig's fire alarm panel issues an alert, the operators on the drilling deck cannot immediately learn about the fire. By the time the fire is broadcast to the operators on the drilling deck, the fire has already been burning for some time, thus threatening the lives of the operators and the safety of the system facilities. Therefore, a workover rig fire video early warning system needs to be designed to solve the above problems. Utility Model Content
