Description
Technical field
The utility model relates to winning equipment field, especially relates to the anti-overspeed alarm that knocks into the back of a kind of mine explosion-suppression and intrinsic safety type.
Background technology
Winning equipment is because the circumstance complication of application, very high requirement is had to the reliability of equipment and safety, particularly for the winning equipment carrying out tunneling, a large amount of flammable explosive gas and dust is there is in tunnel, above-mentioned gas and dust run into naked light and very easily set off an explosion, this just requires that the equipment worked in such a case must meet high-level safety requirements, and all electric equipments must have the characteristic of flame proof and intrinsic safety.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of compact conformation, the anti-overspeed alarm that knocks into the back of mine explosion-suppression and intrinsic safety type of use safety, and the technical scheme of employing is as follows:
The anti-overspeed alarm that knocks into the back of mine explosion-suppression and intrinsic safety type, comprise explosion-proof chamber and intrinsic safety chamber, described explosion-proof chamber is connected by through hole with intrinsic safety chamber, described explosion-proof chamber has dismountable cover plate, described dismountable cover plate and explosion-proof chamber are tamping fixing by bolt, battery is provided with in described explosion-proof chamber, controller circuitry and velocity sensor, intrinsic safety type circuit board is provided with in described intrinsic safety chamber, described intrinsic safety type circuit board connects infrared radar respectively, flashing light and intrinsic safety type alarm, described intrinsic safety type circuit board is connected with controller circuitry by integral shielding cable, described integral shielding cable is through through hole, outer end, described intrinsic safety chamber is provided with glass lens.
Further, the crashproof barrier of metal is also provided with outside described glass lens.
Further, described intrinsic safety chamber is provided with several blow vent.
Further, described through-hole diameter is greater than integral shielding cable size.
Adopt the anti-overspeed alarm that knocks into the back of above-mentioned mine explosion-suppression and intrinsic safety type, compact conformation, use safety, ensure that normally carrying out of mining vehicle.
Accompanying drawing explanation
Fig. 1 is that mine explosion-suppression and intrinsic safety type is prevented knocking into the back the structural representation of overspeed alarm.
Detailed description of the invention
The anti-overspeed alarm that knocks into the back of mine explosion-suppression and intrinsic safety type as shown in Figure 1, comprise explosion-proof chamber 1 and intrinsic safety chamber 2, described explosion-proof chamber 1 is connected by through hole with intrinsic safety chamber 2, described explosion-proof chamber 1 has dismountable cover plate 3, described dismountable cover plate 3 is tamping fixing with explosion-proof chamber 1 by bolt, battery 7 is provided with in described explosion-proof chamber 1, controller circuitry 6 and velocity sensor 13, intrinsic safety type circuit board 5 is provided with in described intrinsic safety chamber 2, described intrinsic safety type circuit board 5 connects infrared radar 8 respectively, flashing light 9 and intrinsic safety type alarm 11, intrinsic safety chamber 2 is also provided with several blow vent 12, for draining the pressure of explosion-proof chamber 1 and inside, intrinsic safety chamber 2, alarm buzzer 11 sound can be made louder simultaneously, described intrinsic safety type circuit board 5 is connected with controller circuitry 6 by integral shielding cable 10, described integral shielding cable 10 is through through hole, through-hole diameter is greater than integral shielding cable 10 diameter, be convenient to lose heart, outer end, described intrinsic safety chamber 2 is provided with glass lens 4, the crashproof barrier 14 of metal is also provided with outside glass lens 4, ground connection that should be good in said apparatus installation.
