Embodiment Construction

[0025] For an implementation example, see figure 1 . In the figure, this laser detonation system consists of a power supply that satisfies the output energy of the laser, a laser power supply numerical control system, a laser array, a laser beam splitter, a laser detonator without explosives, and an optical fiber.

[0026] Several lasers form a laser array, and the power switch of each laser in the laser array is controlled by the power numerical control system, and the delay time can be set by inputting parameters. The laser light emitted by the laser is guided into the laser beam splitter by the optical fiber, and then exported to several splitting optical fibers.

[0027] see figure 2 As shown, insert the bayonet pin fixed on the head of each fiber into the inner groove of the non-priming laser detonator. At this time, the optical fiber just reaches the high laser-sensitivity explosive containing light-absorbing substances in the non-priming laser detonator.

Abstract

The invention relates to a laser initiation system, and belongs to the field of civil explosive apparatuses production. The system is characterized by comprising a laser device adapting power supply (1), a laser device power supply numerical control system (2), a laser device array (3), a laser divider (4), optic fibers (5) and an initiating explosive-free laser detonator (6). A plurality of laser devices are arranged to form the laser device array, a power supply switch of each laser device in the laser device array is controlled by the power supply numerical control system, and the delaying time can be set. The laser generated by the laser device is guided into the laser divider by the optic fibers, and a plurality of laser-dividing optic fibers are guided out. A bayonet pin fixed at the head of each optic fiber is inserted into the bayonet of the initiating explosive-free laser detonator, and then the optic fibers just reach the high-laser sensitive explosive containing the laser absorbing matter in the initiating explosive-free laser detonator. After the power supply is engaged, the power supply numerical control system with set delaying time is started, the laser generated by the laser device array is guided into the laser divider by the optic fibers, and the divided laser can simultaneously initiate the initiating explosive-free laser detonator.

Description

technical field [0001] The invention relates to the field of civil engineering blasting, and in particular provides a laser blasting system. Background technique [0002] At present, the detonating materials at home and abroad are basically electric detonators or nonel detonators. Due to the precise delay of some special projects and the increasingly severe anti-terrorism security requirements, relevant departments have introduced electronic detonators containing microelectronic components and control circuits. Digital Detonator. [0003] Chinese patent, patent number 200820148897.2, discloses a fiber optic connector for laser detonation and ignition system, the specific content is: the utility model relates to a fiber optic connector for laser detonation and ignition system, including a housing and an optical fiber pin assembly, the housing One end is the connecting part of the optical fiber plug, and the other end is the connecting part of the combustion device. There is ...
