Abstract
The utility model relates to a low voltage electric appliance switch and specifically relates to a main rotation switch for gate state monitoring. The main rotation switch is widely used for controlling opening of a valve and a guide blade in a hydraulic power plant. The main rotation switch comprises a box body, wherein the box body is transversely provided with a main rotation shaft. The main rotation switch is characterized in that: the main rotation shaft is parallelly equipped with multiple radial adjusting rods, an outer end face of each adjusting rod is internally provided with a magnet, the adjusting rods are fixed and positioned on the main rotation shaft through locking screws, one edge in the box body is equipped with multiple magnetic induction switches corresponding to the adjusting rods. The main rotation switch has advantages of simple structure, convenient and fast adjustment, simple maintenance, stable operation and shortened maintenance time.
Description
technical field
The utility model relates to a kind of low voltage switch, the rotary command switch of applying in gate status monitoring.Rotary command switch is widely used for the control of hydropower plant gates and guide vane opening.
Background technology
In the prior art, master switch refers to according to the master control electrical apparatus of preset program conversion control circuit wiring.What in the control of water generating gate and guide vane opening, early adopt is cam regulation controller (master switch), and cam rotates with the lifting of gate, control switch closure or disconnection, thus reach the monitoring object to set state.
In debugging and the long-term process of using, cam regulation controller (master switch) mainly reflects following shortcoming: 1, traditional master controller is controlled contact switch owing to adopting, belonging to machinery controls, complicated in mechanical structure, the method of adjusting contact is to be undertaken by visual fix, a contact needs test of many times just can adjust to the right place, and adjustment cycle is long, and contact part fault is more, the life-span is short.2, the contact of also finding cam master controller in service be easily oxidized, adhesion, and coupling rod is easily loosening, causes position contact firmly not connect.3, cam easily slides, thereby produces error, while making this connection of contact, disconnects.4, contact spring is easily loosening, in the time of also can causing this connection of contact, disconnects.
Utility model content
The purpose of this utility model is to provide a kind of machinery-free type contact for above-mentioned deficiency, easy to adjust, the rotary command switch of applying in gate status monitoring that the life-span is long.
Technical solution of the present utility model is: a kind of rotary command switch of applying in gate status monitoring, comprise casing, casing top rail is equipped with rotary main shaft, it is characterized in that being provided with side by side on rotary main shaft many radial adjusting levers, on the outer face of each adjusting lever, be built-in with magnet (magnetic cell), adjusting lever passes through lock screw stationary positioned on rotary main shaft; In casing, corresponding adjusting lever is provided with a plurality of magnetic induction switches on one side.
360 degree dials are installed on rotary main shaft outer end.
The utility model has been avoided complicated mechanical transmission structure, thereby has also avoided shortcoming in prior art.
The utility model has the advantages that: 1, (the more complicated mechanical structure of machinery-free cam-type master switch) simple in structure, non-contact type is controlled, so can there is not wear phenomenon.2, easy to adjust quick, internal structure is simple, has enough adjustment space; With angle dial, convenient adjustment.3, provide analog signals output, multiple metering system.4, easy maintenance, stable, the later stage avoids safeguarding, has greatly reduced later stage work program, has reduced workload, has saved the repair time, is the optimal selection that replaces mechanical cam formula rotary command switch.
Below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structure diagram.
Embodiment
Referring to Fig. 1, parts title is as follows: casing 1, rotary main shaft 2, adjusting lever 3, lock screw 4, magnetic induction switch 5,360 degree dials 6, magnet 7.
A rotary command switch of applying in gate status monitoring, comprises casing 1, and casing 1 top rail is equipped with rotary main shaft 2, is connected with gate feedback position gear.Many radial adjusting levers 3 are installed on rotary main shaft 2 side by side, on the outer face of each adjusting lever 3, be built-in with magnet 7(magnetic cell), adjusting lever 3 can regulate corner around rotary main shaft 2 rotations, and adjusting lever 3 passes through lock screw 4 stationary positioned on rotary main shaft 2; The corresponding adjusting lever 3 in the interior one side of casing 1 is provided with the number of positions that a plurality of magnetic induction switch 5(monitor as required and determines).360 degree dials 6 are installed on rotary main shaft 2 outer ends, facilitate adjusting lever 3 to adjust angle.
Rotary main shaft 2, in rotary course, drives a plurality of adjusting lever 3 rotations, and when rotating to corresponding magnetic induction switch 5, magnetic induction switch 5 actions, send mechanical contacts actuating signal and analog signals.
Describing above, is embodiment of the present utility model, and various not illustrating is construed as limiting flesh and blood of the present utility model.
Claims (2)
1. a rotary command switch of applying in gate status monitoring, comprise casing (1), casing (1) top rail is equipped with rotary main shaft (2), it is characterized in that being provided with side by side on rotary main shaft (2) many radial adjusting levers (3), on the outer face of each adjusting lever (3), be built-in with magnet (7), adjusting lever (3) passes through lock screw (4) stationary positioned on rotary main shaft (2); In casing (1), corresponding adjusting lever (3) is provided with a plurality of magnetic induction switches (5) on one side.
