Abstract

An incomplete gear type electric or manual switch-on device based on an intelligent switch comprises a base, a manual gear, a bearing, a driving gear, a push rod, an incomplete gear and a motor. When the intelligent switch is tripped, a movable rod of the intelligent switch pushes the push rod to the inferior, and the driving gear rotates to a specific position; when switch-on is required, a driving switch of the motor is pressed to drive the motor to rotate counterclockwise to drive the incomplete gear to rotate counterclockwise, the incomplete gear is engaged with the driving gear, the motor continues rotating, then the driving gear rotates to jack up the push rod, and the intelligent switch is pushed to switch on; after the switch-on, the incomplete gear does not rotate beyond a critical position due to a tiny time difference from the completion of the switch-on to that rotation stopping of the motor; and therefore, when the intelligent switch is tripped for a second time, the incomplete gear cannot prevent the driving gear from slewing. The problem that the intelligent switch is required to be switched on manually, and cannot be controlled remotely after the intelligent switch is tripped is solved; in addition, secondary tripping of the intelligent switch is not affected after the switch-on; the device is simple; and the reliability of the device is ensured.

Description

Electronic or the closing by hand device based on the partial gear formula of intelligent switch

Technical field

The invention belongs to the structural design field of the switching-on mechanism of intelligent switch, be specifically related to the electronic or closing by hand device of a kind of partial gear formula based on intelligent switch.

Background technology

At present, electric power system extensively adopts intelligent switch in order to prevent electric power accident, tripping operation outage in time when electric power system is broken down, but can't be independently closed after the tripping operation of present intelligent switch, need to rely on and manually close a floodgate, but when intelligent switch is numerous, rely on manual combined floodgate efficient low, poor reliability, fail safe is low, can't Long-distance Control, the electric switch-on device had appearred afterwards, but part electric switch-on device have after closing a floodgate cause can't secondary trip hidden danger, can't in time break away from the combined floodgate point, I have proposed the electronic of grooved pulley type or closing by hand device in a few days ago, but structure does not reach the simplest standard as yet.

Summary of the invention

Electronic or the closing by hand device based on the partial gear formula of intelligent switch, its purpose must rely on closing by hand after being to solve intelligent switch tripping operation, problem that can not Long-distance Control, and do not influence the secondary trip of intelligent switch after closing a floodgate, have simple in structure, the advantage of dependable performance.

Electronic or the closing by hand device based on the partial gear formula of intelligent switch, by pedestal, manual gear, bearing, driving gear, push rod, partial gear, motor is formed.Intelligent switch is laid in the top of pedestal, and there are two protruding axles that gear is installed the below, and the lower right is useful on the mounting groove that motor is installed; Manual gear is placed on the protruding axle of gear of pedestal lower left, is connected the location by the protruding axle of bearing and gear, and manual gear cooperates with the driving gear on right side, and manual gear does not draw with manual rocking bar mating part; Driving gear is connected the location with the pedestal below protruding axle of idler gear by bearing, and the one side of driving gear has a vertical shaft, matches with the top sliding tray of push rod; One end of push rod has sliding tray, and the other end pushes away the lock groove, pushes away the lock groove and is used for providing the gap to reduce mechanism's processing request, reduces cost; Partial gear has the hole that links to each other that links to each other with motor, and partial gear can be meshed with driving gear.

During use, manual gear, driving gear is connected on the corresponding protruding axle of pedestal by bearing, the sliding tray of push rod matches with the vertical shaft of driving gear, push away the lock groove and match with intelligent switch, motor is installed in the motor mounting groove on the pedestal, and partial gear links to each other with motor.

When the intelligent switch tripping operation, the intelligent switch motion bar is pushed into the below with push rod, driving gear turns to ad-hoc location, when needs close a floodgate, press motor driven switch, drive motors is rotated counterclockwise, the driven by motor partial gear is rotated counterclockwise, partial gear and driving gear engagement, motor continues rotation, and then the driving gear rotation, make push rod by jack-up, the promotion intelligent switch closes a floodgate, and after closed action is finished, stops motor and rotates a small time difference is arranged owing to close a floodgate to be accomplished to, make partial gear turn over critical localisation, so when the intelligent switch secondary trip, channel bar can not stop the revolution of driving gear.

Should be understood that, in order to reduce cost, the present invention does not add any motor angle control feedback device, so after combined floodgate is finished, can not continue drive motors for a long time, should make not exclusively to be in driving gear to be in non-engagement state, prevent from influencing the tripping operation of intelligent switch, to have the part of tooth not have toothed portion relatively less because of partial gear, guaranteed the reliability of mechanism, fail safe.

In summary, must rely on closing by hand after the invention solves intelligent switch tripping operation, problem that can not Long-distance Control, and do not influence the secondary trip of intelligent switch after closing a floodgate, mechanism is simple, has guaranteed mechanism reliability.

Embodiment

Below by example and accompanying drawing thereof the present invention is described in further details;

Referring to Fig. 1, this stereogram electronic based on the partial gear formula of intelligent switch or closing by hand device driving gear, the protruding axle of driving gear 1 and pedestal 7 below idler gears 6 is connected the location by bearing, the one side of driving gear 1 has a vertical shaft 2, match driving gear 1 right side and partial gear 9 engagements with the top sliding tray 5 of push rod 3.

Referring to Fig. 2, this stereogram electronic based on the partial gear formula of intelligent switch or closing by hand device push rod, an end of push rod 3 has sliding tray 5, and the other end pushes away lock groove 4, pushes away lock groove 4 and is used for providing the gap to reduce mechanism's processing request, reduces cost.

Referring to Fig. 3-Fig. 4, this combined floodgate starting and ending position critical localisation schematic diagram electronic based on the partial gear formula of intelligent switch or closing by hand device push rod, during use, manual gear 12, driving gear 1 is connected on the pedestal 7 corresponding protruding axles by bearing respectively, intelligent switch 13 is laid in the top of pedestal 7, and the lower right is useful on the mounting groove that motor is installed; Manual gear 12 cooperates with the driving gear 1 on right side, and manual gear 12 does not draw with the rocking bar mating part; The sliding tray 5 of push rod 3 matches with the vertical shaft 2 of driving gear 1, pushes away lock groove 4 and matches with intelligent switch 13, and motor 18 is installed in the motor mounting groove on the pedestal 7, and partial gear 9 links to each other with motor 8.When intelligent switch 13 tripping operations, the intelligent switch motion bar is pushed into the below with push rod 3, driving gear 1 turns to ad-hoc location, when needs close a floodgate, press motor 8 driving switchs, drive motors 8 is rotated counterclockwise, driven by motor partial gear 9 is rotated counterclockwise, partial gear 9 and driving gear 1 engagement, motor 8 continues rotation, and then driving gear 1 rotation, make push rod 3 by jack-up, promote intelligent switch 13 and close a floodgate, after closed action is finished, stop motor 8 and rotate a small time difference is arranged owing to close a floodgate to be accomplished to, make partial gear 9 turn over critical localisation, so when the intelligent switch secondary trip, partial gear 9 can not stop the revolution of driving gear 1.
