Remote executing mechanism of smoke exhaust valve

The invention relates to a remote executing mechanism of a smoke exhaust valve. The remote executing mechanism comprises a shell, a swing rod, a swing frame and a winch are rotatably installed on a bottom plate of the shell, a pawl is arranged on the swing frame, an electromagnet is arranged on the bottom plate of the shell, and a mandrel of the electromagnet is connected with the head end of the swing rod; in an initial condition, the electromagnet is powered off, the mandrel extends out, the tail end of the swing rod clamps the head end of the swing frame, and the pawl on the swing frame is unidirectionally clamped with a ratchet wheel; a swing frame opening and the ratchet wheel are opposite in the direction, a swing frame shaft penetrates through a top steel plate and a bottom steel plate; a main torsion spring is sleeved on the shaft section of the swing frame shaft between the bottom steel plate and the bottom plate of the shell; the pawl is hinged to the shaft section of the swing frame shaft between the bottom steel plate and the top steel plate, and the shaft section of the swing frame shaft between the pawl and the top steel plate is sleeved with an auxiliary torsion spring; and a rectangular through hole is formed in a side steel plate of the swing frame, the outer end of the pawl extends out of the rectangular through hole, and a striker portion protrudes out of the rear side surface of the pawl. The remote executing mechanism not only can reduce the blocking probability of the contact part of the tail end of the swing rod and the head end of the swing frame, but also can prevent the contact part of the pawl and the ratchet wheel from being blocked.
