[0003] The patent specification with the announcement number CN217897819U discloses a cementing pulsation device for cementing in petroleum engineering, including a box body, a protective mechanism is arranged in the box body, and the protective mechanism is composed of a support frame, a pulsator body, a shock-absorbing rubber plate, a spring A and a flexible rubber ring. A support frame is arranged in the box body, and the pulsator body is installed in the support frame. A shock-absorbing rubber plate and a spring A are installed between the support frame and the box body, and there are multiple groups of shock-absorbing rubber plates and springs A. A connecting hole is opened on the outer wall surface of the box body, and there are two groups of connecting holes. A through hole is opened on the top surface of the box body, and flexible rubber rings are bonded to the inner periphery of the through hole and the inner periphery of the connecting hole.
