Abstract
The invention discloses a novel emergency plugging box mechanical interlocking device. With the device adopted, the following mechanical interlock functions can be realized: when a plug and a socket are not in reliable butt joint, a power source switch cannot be closed; and when the switch is closed, plugging and pulling-out operation cannot be performed on the plug and the socket. The novel emergency plugging box mechanical interlocking device of the invention mainly comprises a plug, a socket, a flexible shaft transmission mechanism, a movable limiting stretchable head and a circuit breaker rotating handle. By means of flexible shaft transmission, the movable limiting stretchable head can stretch out or retract, so that the enabling and withdrawal of a mechanical interlocking function can be realized.
Description
Technical field
The present invention relates to naval ship accident power distribution system equipment, particularly relate to inside a kind of emergent connecting box for realizing the device of mechanical interlocking function。
Background technology
Mainly on naval vessel, daily distribution system uses when wrecking accident distribution system, it is connected across in the section of damage cabin by drawing deposited flexible cable to be coupled together by emergent connecting box accordingly temporarily, to guaranteeing that the important load such as ship navigation, safety provides temporary electrical power, thus improving the vitality on naval vessel。When use accident distribution system, it is energized again after first the two ends flexible cable with socket and emergent connecting box being connected。For guaranteeing safety when accident distribution system uses, arranging a mechanical interlocks between chopper with socket in emergent connecting box domestic demand: when reliably not docking when plug and socket, on and off switch can not close；When the switch is closed, it is impossible to plug and socket are carried out plug operation。
The mechanical interlock mechanism of current application realizes function by gear drive, substantially can realize mechanical interlocking purpose, but there is the problems such as structure complexity, assembly precision requirement is high, fault rate is high, use is inconvenient。
Summary of the invention
For the defect of prior art, the invention provides a kind of novel mechanical interlocks, under realizing its mechanical interlocking function premise, can have the features such as structure composition simple, reliability height, good operability。
The invention mainly comprises the parts compositions such as plug, socket, flexible shaft transmission mechanism, mobilizable limit telescopic head, rotary handle of circuit breaker。Mobilizable limit telescopic head is made to stretch out or regain by soft axle transmission, it is achieved the input of mechanical interlocking function and exiting。Implement function as follows:
1), when plug is not inserted into, chopper cannot close a floodgate；Only when, after plug insertion socket, chopper can close a floodgate。
Chopper end is provided with mobilizable limit telescopic head。When plug is not inserted into, limit telescopic head stretches out, and blocks the path of motion of rotary handle of circuit breaker, makes chopper to close a floodgate；Plug by soft axle transmission, makes limit telescopic head regain after inserting, and releases the interlocking to chopper。Stretching out and regaining of limit telescopic head is realized by the tension force of flexible axle。
2), after breaker closing, plug cannot be extracted；Only when chopper is in gate-dividing state, just plug can be carried out plug operation。
Connector assembly end is provided with mobilizable limit telescopic head。After breaker closing, by soft axle transmission, making limit telescopic head stretch out, that blocks plug extracts path, makes plug to extract；After breaker open operation, limit telescopic head is regained, and releases the interlocking to connector assembly。Stretching out and regaining of limit telescopic head is realized by the tension force of flexible axle。
The mechanical interlock mechanism of the present invention, according to real work electric current, can be arranged one or more groups connector assembly, and mechanical interlocking function is constant, differs only in only when whole connector assemblies all reliably docks, and chopper can close a floodgate；After breaker closing, all of plug all cannot be extracted。
Detailed description of the invention
The present embodiment is mainly made up of plug, socket, slide block, flexible axle, flexible axle length adjuster, limit telescopic pin, support, rotary handle of circuit breaker etc.。Limit telescopic head action is made, it is achieved following interlock by flexible axle tension force:
1), when plug is not inserted into, chopper cannot close a floodgate；Only when, after plug insertion socket, chopper can close a floodgate。
When plug is not inserted into, flexible axle is absent from tension force, and chopper end limit telescopic pin is in free state, and limit telescopic head stretches out the limited block blocking on rotary handle of circuit breaker, and chopper can not close a floodgate；
When a plug is to be inserted into the socket, being located at the slide block that plug front portion limited block withstands in socket, slide block moves up because of stress, make associated flexible axle tighten, transmit power to chopper end limit telescopic pin so that it is limit telescopic head is retracted, releasing the interlocking to chopper, chopper can close a floodgate；
When plug is extracted, under the effect of flexible axle tension force, slide block is reset to bottom, and flexible axle tension force disappears thereafter, and chopper end limit telescopic pin affranchises state, and limit telescopic head stretches out the limited block blocking on rotary handle of circuit breaker, and chopper can not close a floodgate。
2), after breaker closing, plug cannot be extracted；Only when chopper is in gate-dividing state, just plug can be carried out plug operation。
Being provided with gap in the middle part of socket chute, after breaker closing, its rotary handle of circuit breaker loses coupled flexible axle tension force, socket end limit telescopic pin is made to be in free state, now limit telescopic head stretches out, and blocks the limited block on plug in gap, and plug can not be extracted。
After breaker open operation, coupled flexible axle is produced tension force by rotary handle of circuit breaker, makes the limit telescopic head in socket end limit telescopic pin regain from the gap of socket, releases the interlocking to plug, and plug can be extracted。
Double socket is met an urgent need connecting box mechanical interlocks, and its operation principle is similar with the emergent connecting box mechanical interlocks of single-socket, is distinctive in that chopper can close a floodgate only when whole connector assemblies all reliably docks；After breaker closing, all of plug all cannot be extracted。
Obviously, those skilled in the art, it is possible to the present invention is carried out various change and deformation without deviating from the spirit and scope of the present invention。So, if these amendments and deformation belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention also anticipatesFigureComprise these to change and deformation。
