Abstract
The utility model relates to the technical field of knife switches, in particular to a novel storage battery knife switch which comprises a knife switch body and an installation plate. A safety protective cover is covered on the knife switch body, a quick-action switch is arranged on one side of the installation plate, a warning mark is further arranged on the safety protective cover, and dustproof level of the quick-action switch is IP60. After the knife switch body is opened, the protective cover is separated from the quick-action switch so as to enable a normally closed auxiliary contact in the quick-action switch to be closed. Electricity is supplied to a locomotive parking brake module through the normally closed auxiliary contact, at the moment a stationary locomotive has a brake function, and the locomotive is prevented from sliding in a stationary state. The protective cover can prevent operators from contacting a copper bar on the knife switch body, and the warning mark reminds the operators to be careful of electric shock. The novel knife switch is safe, reliable, simple in structure, convenient to use and capable of being applied to all internal combustion locomotives.
Description
Technical field
The utility model relates to the technical field of knife switch, especially a kind of novel storage battery knife switch.
Background technology
Use at present the storage battery knife switch on diesel locomotive, also do not have protective cover, do not have quick-action switch, after the storage battery knife switch disconnects, power supply is provided can't for the parking brake module, locomotive under static state can slip the phenomenon of car and cause danger.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel storage battery knife switch.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel storage battery knife switch, comprise knife switch and mounting panel, and be covered with safty shield at described knife switch, be provided with quick-action switch in described mounting panel one side.
According to another embodiment of the present utility model, comprise that further described safty shield is provided with alarming sign.
According to another embodiment of the present utility model, comprise that further it is the quick-action switch of IP60 that described quick-action switch adopts dustproof grade.
The beneficial effects of the utility model are, be covered with safty shield at existing storage battery knife switch, after mounting panel one side is provided with quick-action switch, after the storage battery knife switch disconnects, the safty shield that covers on the knife switch separates the normally closed auxiliary contact closure that quick-action switch makes the quick-action switch the inside, provide power supply by this normally-closed contact to the locomotive parking brake module, this moment, static locomotive had braking function, can prevent that locomotive under static state slipping car; Safty shield on the storage battery knife switch can also prevent the copper bar on operating personnel's touching Rnife switch, and the alarming sign that safty shield is provided with can be reminded operator's danger,High Voltage.This Novel knife switch is safe and reliable, and is simple in structure, easy to use, can be generalized on all diesel locomotives.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is front view of the present utility model;
Fig. 2 is end view of the present utility model;
Fig. 3 is quick-action construction of switch figure in the utility model.
1. knife switches among the figure, 2. mounting panel, 3. safty shield, 4. quick-action switch, 4.1. often opens auxiliary contact, the normally closed auxiliary contact of 4.2..
Embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of novel storage battery knife switch comprises knife switch 1 and mounting panel 2, is covered with safty shield 3 at knife switch 1, be provided with quick-action switch 4 in mounting panel 2 one sides, quick-action switch 4 comprises often leaves auxiliary contact 4.1 and normally closed auxiliary contact 4.2.Wherein safty shield 3 is provided with alarming sign.It is the quick-action switch of IP60 that quick-action switch 4 adopts dustproof grade.
The utility model is when storage battery knife switch 1 is closed, and the safty shield 3 that covers on the storage battery knife switch 1 is pressed on the quick-action switch 4, makes often to open auxiliary contact 4.1 closures on the quick-action switch 4, and normally closed auxiliary contact 4.2 disconnects.After storage battery knife switch 1 disconnects, the safty shield 3 that covers on the storage battery knife switch 1 separates quick-action switch 4, make normally closed auxiliary contact 4.2 closures on the quick-action switch 4, often driving auxiliary contact 4.1 disconnects, normally closed auxiliary contact 4.2 closures of quick-action switch 4, power supply is provided for the locomotive parking brake module, can prevent that locomotive under static state slipping car, cover on safty shield 3 on the storage battery knife switch 1 and can also prevent copper bar on operating personnel's touching Rnife switch 1, the alarming sign that safty shield 3 is provided with can be reminded operator's danger,High Voltage.This Novel knife switch is safe and reliable, and is simple in structure, easy to use, can be generalized on all diesel locomotives.
