For the problems referred to above, at present effective solution is not yet proposed.
Utility model content
For the problem in correlation technique, the utility model proposes a kind of flame proof switch, the problem that cannot use under mine because of safety problem switch can be solved.
The technical solution of the utility model is achieved in that
A kind of flame proof switch, comprise casing, described casing is provided with some interfaces, wherein, switch body is provided with in described casing, it is characterized in that, in described casing, be also provided with explosion-proof chamber and wire connection cavity, in described explosion-proof chamber, be provided with intrinsically safe circuit, output and the input of described intrinsically safe circuit are provided with isolation module, described intrinsically safe circuit is connected with switch body, and in addition, described wire connection cavity is connected with interface.
Further, CAN module and RS485 module is connected in parallel between described intrinsically safe circuit and switch body.
Further, described intrinsically safe circuit comprises battery charging and discharging control board, and described battery charging and discharging control board is in series with rectifier successively, control transformer, fuse and rectifier diode, described battery charging and discharging control board is also provided with buzzer, and described buzzer connects to be gone up on the transformer.
Wherein, described switch body is provided with some network interfaces.
The beneficial effects of the utility model: by being arranged on the explosion-proof chamber in anti-explosion box body, switch body is provided with in explosion-proof chamber, and, intrinsically safe circuit is provided with in explosion-proof chamber, and intrinsically safe circuit is provided with isolation module, and then make the utility model not only have the function of switch, flame proof circuit simultaneously by arranging can also make switch have more fail safe at work, ore deposit underground work can be applied to, in addition, the utility model also has safe and practical, and structure is simple, the features such as cost of manufacture is low.
