Most of the existing pumping units adopt the belt form transmission, because it needs to be operated in the wild for a long time, and the bad working environment can cause the damage of the belt and even affect the operation of the whole mechanism, so the technical personnel usually designs the shell type cover to protect the belt part;

[0003] Now some pumping unit protection devices generally adopt the design that the fine mesh type metal mesh cover is arranged in the coaming. The fine mesh of the metal mesh cover effectively blocks the invasion of external impurities such as dust and gravel, thereby protecting the internal mechanical parts of the pumping unit from damage, however, although the protection device meets the basic safety requirement in function, a series of problems are exposed in the actual installation and maintenance process. Especially the connecting mode between the metal mesh cover and the coaming, usually a plurality of bolts are fixed through the reinforced edge of the coaming. This connecting mode is not only cumbersome to operate, time-consuming, but also requires professional tools for fastening, which undoubtedly increases the operation difficulty and time cost of the maintenance personnel, so we propose the pumping unit protection device to solve the above problems.
