Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
The power attenuating device as shown in figure 1, a kind of stern of the present invention impulses, including top panel 1 and lower shoe 2, institute
State and some buffer gears are connected between top panel 1 and lower shoe 2, some buffer gears are set in array spaced reciprocally；Institute
Stating buffer gear includes connecting rod 4 and cushion dashpot 3, be provided with cushion dashpot 3 can along its up and down piston 41, the lower end of connecting rod 4 with
Piston 41 is fixedly connected, and the upper end of connecting rod 4 coordinates in connection is contradicted with top panel 1, is provided between the bottom of cushion dashpot 3 and lower shoe 2
Buffer spring 21；The shock loading that the top panel 1 is subject to passes through the action of connecting rod 4 and piston 41, the inner chamber of change cushion dashpot 3
Volume realizes the transformation of kinetic energy and pressure, and part shock loading is changed into elastic potential energy by cushion dashpot 3 by buffer spring 21, from
And reduce the impact and vibrations to lower shoe 2 and its rear structure；The both ends connection cushion dashpot 3 of the buffer spring 2 is with
Bottom plate 2, so that cushion dashpot 3 under the shock loading in non-vertical direction, changes self-view, passes through the elasticity of buffer spring 21
Power eliminates shock loading and recovers form, so as to meet the damping requirement under water body environment under complicated impulsive force, adequately protects
Hull structural strength and stability.
Be provided with partition panel 31 in the cushion dashpot 3, partition panel 31 by the inner chamber of cushion dashpot 3 be divided into or so two it is independent
Cavity 32, what the bottom of partition panel 31 was communicated with left and right cavity 32 walks fluid apertures 33, and brake fluid 34 is filled with cushion dashpot 3,
The passage 35 of connection right chamber body 32 is offered in the side wall of cushion dashpot 3；The upper end of cushion dashpot 3 is provided with guide cylinder 36, is oriented to
The lower port of cylinder 36 connects with right chamber body 32, and connecting rod 4 and piston 41 can be up and down along guide cylinder 36；The connecting rod 4 and piston
41 along guide cylinder 36 action can change the cavity volume of cushion dashpot 3, when the pressure-bearing piston 41 of top panel 1 along guide cylinder 36 descending, right chamber
Brake fluid 34 in body 32 enters left chamber body 32 along fluid apertures 33 is walked, in left chamber body 32 pressure increase air is squeezed from passage 35
Go out, impulsive force is eliminated by the transformation of mechanical energy and pressure；After impulsive force eliminates, liquid level and pressure in left chamber body 32 are above
Right chamber body 32, cushion dashpot 3 recover vertical state in the presence of buffer spring 2 first, and the brake fluid 34 under Action of Gravity Field is from a left side
Cavity 32 is back to right chamber body 32, and then promotes piston 41 to rise and restPose.
The cushion dashpot 3 is vertically arranged, and passage 35 is in the ullage of the inside brake liquid 34 of cushion dashpot 3, walks fluid apertures 33
Below liquid level in the inside brake liquid 34 of cushion dashpot 3；The passage 35 can be pulled open and the liquid level of brake fluid 34 by extended structure
Between drop, so as to play the liquid viscosity of brake fluid 34, improve the bearing strength of cushion dashpot 3.
The passage 35 is provided with the gas permeable biofilm that can separate brake fluid 34, and currently preferred passage 35 is set
Gas permeable biofilm be avoided that brake fluid 34 flows out from passage 35, set, can be achieved by the volume ratio of left and right cavity 32
The limit control of the stroke of piston 41.
The spherical structure setting in bottom of the cushion dashpot 3, the overall of cushion dashpot 3 use symmetrical structure all around, delayed
The bottom for rushing cylinder 3 is more than the section of guide cylinder 36 so as to form tumbler structure, makes it can be in buffer spring 21 after being impacted
Effect is lower can Rapid reset.
The bottom surface of the top panel 1 is provided with some and one-to-one arc groove 11 of buffer gear, the upper end of connecting rod 4
To in arc groove 11, and the spherical structure setting in upper end of connecting rod 4, arc groove 11 and the upper end mating spherical surfaces of connecting rod 4,
It is flexibly connected so that top panel 1 and connecting rod 4 are in, and when the vertical angle of cushion dashpot 3 changes, the upper end of connecting rod 4 will not be with
There is displacement in top panel 1, further reduces the complexity of structure.
Described above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application scope,
The equivalent change or modification that feature and principle are done, is included in the range of present patent application.
