Description
Technical field
The utility model relates to blasting technology field, particularly a kind of controlled in wireless detonating primer.
Background technology
Explosive be one can be within the utmost point short period of time material of acutely burning (i.e. blast), can, under the effect of certain outside energy, be blasted by self-energy.Generally, the chemistry of explosive and physical properties are stable, no matter but environment whether seal, dose is how many, even, the in the situation that of extraneous zero oxygen supply, as long as there is stronger energy (priming explosive provides) to excite, explosive will carry out stable detonation formula work done to external world.When explosive charge, can discharge a large amount of heat energy and produce high temperature and high pressure gas, ambient substance being played to the effects such as destruction, throwing, compression.
Explosive is generally divided into two large classes according to packaged form: packing explosive and bulk explosives, wherein pack explosive comparatively common, and comprise the package of all size, packed, case dress.And bulk explosives refers to the explosive that relies on on-the-spot filling equipment to carry out powder charge completely.。The explosion of bulk explosives, except needs bulk explosives itself, also needs initiating equipment (comprising priming bomb and detonator) to ignite it.In blasting operation, tend to use bulk explosives, packing explosive and initiating equipment simultaneously, or do not adopt bulk explosives and all employing packings explosive.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of safe, easy to operate controlled in wireless detonating primer that uses.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of wireless remote control detonating primer, comprise wireless remote control emitter and wireless receiving detonation circuit, described wireless remote control emitter uses the miniature remote controlled projector of finished product quadruple linkage of built-in H9236D module; Described wireless receiving detonation circuit comprises the power source circuit, wireless receiving pilot circuit, oscillation step-up circuit and the charge-discharge circuit that connect successively, and the output terminal of described charge-discharge circuit is connected with electrical detonator.
The beneficial effects of the utility model are, the utility model can use in the scope in the about 100m of distance, can in the process of explosion, guarantee operator's safety, and easy to operate.
As preferred version, the skin of described wireless receiving detonation circuit scribbles one deck water-tight corrosion-proof corrosion material.Circuit card outside be coated with water-tight corrosion-proof corrosion material be placed on the environment that water or corrosion material exist for circuit card in time, be not subject to the impact of external environment, circuit card is difficult for being etched.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, technical solutions of the utility model are further illustrated:
Fig. 1 is the schematic circuit of the wireless receiving detonation circuit of the utility model controlled in wireless detonating primer.
Embodiment
As shown in Figure 1, the utility model wireless remote control detonating primer, comprises wireless remote control emitter and wireless receiving detonation circuit, and wireless remote control emitter uses the miniature remote controlled projector of finished product quadruple linkage of built-in H9236D module; Wireless receiving detonation circuit comprises power source circuit, wireless receiving pilot circuit, oscillation step-up circuit and charge-discharge circuit.Wireless receiving pilot circuit is made up of wireless receiving module IC, resistance R 1, resistance R 2, the first triode VT1, the second triode VT2, the first relay K 1, the second relay K 2, the first diode VD1 and the second diode VD2; Oscillation step-up circuit is made up of normally open contact, resistance R 3, the 3rd triode VT3, step-up transformer T and the 3rd diode VD3 of the first relay K 1; Charge-discharge circuit is made up of the normally open contact of resistance R 4, resistance R 5, polar capacitor C1, polar capacitor C2, power switch Sb and relay K 2.The connection of antenna receiving end of wireless receiving module IC is the input terminus of wireless receiving pilot circuit, and the first relay K 1 and the second relay K 2 are two output terminals of wireless receiving module IC; The normally open contact of the first relay K 1 is the input terminus of oscillation step-up circuit, the output terminal that the negative pole of the 3rd diode VD3 is oscillation step-up circuit; The input terminus of the just very charge-discharge circuit of polar capacitor C1, the output terminal that the normally open contact of the second relay K 2 is charge-discharge circuit.Power source circuit, wireless receiving pilot circuit, oscillation step-up circuit are connected successively with charge-discharge circuit, the output termination electrical detonator of charge-discharge circuit.
Principle of work of the present utility model, while pressing the A key on remote control transmitter, wireless receiving module IC arrives wireless signal by antenna reception, its A end output high level, make the first triode VTl saturation conduction, the first relay K l energising adhesive, the normally open contact of the first relay K l is connected, oscillation step-up circuit energising work, intermittently conducting of the 3rd triode VT3, make the winding of step-up transformer T produce 800V high pressure, this voltage charges to the first polar capacitor Cl and the second polar capacitor C2 after the 3rd diode VD3 rectification and resistance R 4 current limlitings.About 5s left and right, click again the D key of remote control transmitter, the D end of wireless receiving module IC becomes high level, make the second triode VT2 conducting, the second relay K 2 adhesives, the normally open contact of the second relay K 2 is connected, and the first polar capacitor Cl and the second polar capacitor C2 pass through the normally open contact of resistance R 5 and the second relay K 2 to electrical detonator rapid discharge, and electrical detonator is ignited.Meanwhile, the A end of wireless receiving module IC becomes lower level, makes the first triode VT1 cut-off, and the first relay K l discharges, and oscillation step-up circuit power-off quits work.
Device is selected: wireless receiving module IC is NRF401 type, and the first triode VT1, the second triode VT2 and the 3rd triode VT3 are 9013 types, and the first diode VD1, the second diode VD2 and the 3rd diode VD3 are 1N5492 type.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
