Abstract
The invention relates to a detonation type operating mechanism which comprises a cylinder body. A piston with a piston rod is arranged in the cylinder body, a cover plate with a through hole is arranged at the opening end of the cylinder body, the piston rod penetrates out of the through hole of the cover plate and then is connected with an external stress rod, an annular step face is arranged on the side wall of a cavity in the bottom of the cylinder body, the bottom of the piston makes contact with the annular step face so that a sealed section for containing explosives can be reserved between the piston and the bottom of the cylinder body, and the cylinder body is further provided with an electric spark ignition device which deeply stretches into the sealed section to ignite the explosives. According to the detonation type operating mechanism, switching on power is provided for a switch through the strong push force generated at the moment of the explosion of the explosives, and the switching-on time is shorter than 5 ms.
Description
Technical field
The present invention relates to a kind of deflagration type operating mechanism.
Background technology
Traditional switch spring operating mechanism, its machine driving link and driving parts are many, be subject to the restriction of each part quality inertia of transmission link, spring stored energy can not discharge within the extremely short time, spring energy-storage keeps by pallet, during combined floodgate, need to back down pallet retracting spring by closing coil, the response time is slow, therefore with the switch closing time of spring operating mechanism, is difficult to meet the specification requirement of < 25ms.The current domestic spring operating mechanism that also there is no < 25ms operate time.
Traditional electromagnetic operating mechanism, is subject to the restriction of coil impedance, and its feed motion time can not meet the specification requirement of < 25ms.
Summary of the invention
The present invention is directed to the problem that above-mentioned prior art exists and make improvement, technical problem to be solved by this invention is to provide a kind of deflagration type operating mechanism, utilizes explosive detonation moment to produce powerful thrust, to switch, provides combined floodgate power, and closing time is less than 5ms.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of deflagration type operating mechanism, comprise cylinder body, in described cylinder body, be provided with the piston with piston rod, described cylinder body open end is provided with the cover plate with through hole, described piston rod is connected with outside stressed member from cover plate through hole passes, described cylinder base cavity lateral is provided with annular terrace, described piston base contacts with annular terrace, so that leave between piston and cylinder base between the seal area of explosive, on described cylinder body, be also provided with and go deep into the spark ignition device that explosive ignited sealing interval.
Further, on all sidewalls of described piston, be provided with antifriction metal (AFM) sealing ring.
Further, described upper cover of piston rod is provided with the back-moving spring that forces piston base to contact with annular terrace in cylinder body, and the top of described back-moving spring acts on cover plate, and its underpart acts on piston,
Further, described cover plate with several bolt-lockings on cylinder body.
Compared with prior art, the present invention has following beneficial effect:
1, utilize explosive detonation moment to produce powerful thrust, to switch, provide combined floodgate power, closing time is less than 5ms;
2, utilize spark ignition, response speed is exceedingly fast, closing time < 5ms.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the embodiment of the present invention.
In figure: between 1-seal area, 2-cylinder body, 21-annular terrace, 3-spark ignition device, 4-wear-resistant seal ring, 5-cover plate, 6-piston, 61-piston rod, 7-back-moving spring.
Embodiment
Embodiment mono-: as shown in Figure 1, a kind of deflagration type operating mechanism, comprise cylinder body 2, in described cylinder body 2, be provided with the piston 6 with piston rod 61, described cylinder body 2 open ends are provided with the cover plate 5 with through hole, described piston rod 61 is connected with outside stressed member from cover plate 5 through holes pass, described cylinder body 2 bottom cavity lateral are provided with annular terrace 21, described piston 6 bottoms contact with annular terrace 21, so that leave between the seal area of explosive 1 between piston 6 and cylinder body 2 bottoms, on described cylinder body 2, be also provided with and go deep into the interval 1 pair of spark ignition device 3 that explosive ignites of sealing.
In the present embodiment, be enhanced leaktightness effect, on all sidewalls of described piston 6, be provided with wear-resistant seal ring 4.
In the present embodiment, be arranged with the back-moving spring 7 that forces piston 6 bottoms to contact with annular terrace 21 in cylinder body on described piston rod 61, the top of described back-moving spring 7 acts on cover plate 5, and its underpart acts on piston 6,
In the present embodiment, described several bolt-lockings of cover plate 5 use are on cylinder body 2.
When this mechanism is used, when spark ignition device 3 receives reclosing command, explosive between instantaneous ignition seal area in 1, the powerful explosion thrust of explosive detonation 1 interior generation between seal area is supper-fast toward extrapolation by piston rod 61, drive switch combined floodgate parts to complete feed motion, closing time < 5ms; After finishing using, this mechanism takes off powder charge again.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
