Description

Wellhead protection device for lifting main well Technical Field The utility model relates to the technical field of wellhead protection devices, in particular to a wellhead protection device for lifting a main well. Background Early wellhead protection devices were relatively simple and single-function. For example, some simple wellhead fences or cover plates are mainly used for preventing personnel from falling into the wellhead carelessly, but for other risks, such as preventing objects above the wellhead from falling into the well, resisting the influence of severe weather on wellhead equipment and the like, the protection effect is limited, and the traditional wellhead protection device may not fully consider the special requirements and complex working conditions of different wellheads in design. For example, in some high-temperature and high-pressure oil and gas wellhead, a common protective material may not bear a severe working environment and is easy to deform and damage, so that the protective performance is reduced in the fields of petroleum, natural gas exploitation, mine exploitation and the like, and the wellhead is a key part. When using the well head protection, traditional well head protective equipment generally protects through simple baffle, receives serious striking back, very easily drops at the well head, and current adult and child collide highly different, but current protector is limited to the object striking of not co-altitude to the protection effect of device has been reduced. Disclosure of utility model The utility model aims to provide a wellhead protection device for lifting a main well, which aims to solve the problems that the existing wellhead protection device proposed in the background art generally protects through a simple baffle plate, is extremely easy to fall off at the wellhead after being impacted seriously, and has different collision heights between the existing adults and children, however, the existing protection device has limited impact on objects with different heights, so that the protection effect of the device is reduced.
