Description
Technical Field
The invention belongs to the technical field of blasting equipment, and particularly relates to a false touch prevention switch and a detonation device.
Background
In engineering blasting, the common initiation methods are: an electric detonation method, a detonating cord detonation method, a detonating tube detonation method; the electric initiation method is a detonation aromatic method for detonating explosives by exploding detonators with electric energy. The required equipment comprises the following components: an electric detonator, a lead and a detonation power supply; the connection mode of the electric explosion network is selected according to the explosion method, the explosion scale, the importance of engineering, the selected initiation power supply, the initiation capacity and the like, and the basic connection mode comprises the following steps: series, parallel, series-parallel, parallel-series, etc.; the electric initiation method has the advantages of safety, reliability, accuracy, high efficiency and the like, and still occupies a large proportion at home and abroad. In large and medium-sized blasting, electric power initiation is still mainly used. Particularly in the environment with gas and mine dust explosion, electric initiation is the main initiation method. However, the electric initiation is easily interfered by various electric signals to cause early explosion, so that the common electric detonator cannot be used in the environment with stray electricity, static electricity, thunder, radio frequency electricity and high-voltage induced electricity.
The fuse detonating method is to utilize a fuse to transmit flame to ignite a detonator so as to detonate explosive. The materials required for this initiation method are: fuse, detonator and ignition material; the blasting method of the fuse has the advantages of simple and flexible operation, convenient use and lower cost, and is widely applied to small-sized blasting and tunneling. The accident accounts for the largest proportion in the blasting due to the defects of quick combustion, slow combustion and the like of the blasting fuse; the explosive cannot be detonated at multiple positions simultaneously; the blasting time cannot be accurately controlled, the one-time blasting scale is small, and the toxic gas in the blasting area is increased; the detonation on the water spraying working surface is unreliable, and the network cannot be checked by instruments.
The method of directly detonating the explosive charge with the detonating cord is called detonating cord detonating method. The detonating fuse is first detonated with a detonator, and the explosive is detonated when the detonation wave of the detonating fuse is transmitted to the explosive package. The aim of millisecond blasting of the detonating cord can be achieved by connecting the detonating cord into a secondary blasting tube at a place where delayed sectional detonating is needed; the blasting method needs the following initiation materials: detonators, detonating cords, relay tubes, and the like; the common use of detonating cord is: series, cluster parallel, unidirectional segmented parallel, bidirectional segmented parallel, and the like.
The detonating method of the detonating tube is a method for detonating a detonator by using the shock wave transferred by the detonating tube so as to detonate an explosive. The detonating accident of early explosion caused by the interference of various external calls is fundamentally reduced by the detonating tube detonating method, the detonating network is simple to connect, and complex resistance balance and network calculation are not needed; but the quality of the detonating network cannot be checked by using the instrument; the detonating method of the detonating tube requires the following materials: firing elements (firing guns, firing pens, high-voltage electric sparks, electric firing heads, fire detonators, electric detonators, detonating cords and the like), booster elements (detonating tubes), connecting devices, detonators and the like; the detonating network of the detonating tube comprises a cluster connection (a network integrating the detonating tubes of blast holes into one bundle and connecting with a connecting device), a cluster parallel connection (a connecting network connecting two or more groups of cluster connections to one connecting device in parallel), a cluster series connection (a plurality of groups of cluster connecting networks are connected in series) and other detonating networks.
In the initiation device adopting the initiation method, most of the initiation devices need a switch element to start an initiation program, in the prior art, most of the switch elements adopt a button or a pressing rod structure as a main body to realize a switch function, however, in the actual operation process, because the button or the pressing rod structure has activity, the initiation device is easily mistakenly touched by external force, the initiation program is accidentally started, great potential safety hazards exist, and the initiation device is not favorable for enterprise development.
