Description

Relay connecting device for electronic detonator priming circuit

Technical Field

The utility model relates to an electron detonator auxiliary assembly field. More specifically, the utility model relates to an electronic detonator priming circuit relaying connecting device.

Background

With the development of blasting industry, the electronic detonator priming circuit has been gradually popularized and popularized, and gradually becomes a main priming device for open blasting. The electronic detonator has the obvious process characteristics of high delay precision, realization of network delay parameters in a detonator internal chip, optional setting of delay time (within a timing range allowed by the chip), realization of complex network design by fewer initiating devices, high reliability, good safety performance, simple network connection, high intelligent level and the like, and can gradually replace the traditional initiating network (an electric explosion network, a detonating tube network, a detonating cord network and a composite initiating network formed by the same). When an electronic detonator priming circuit is laid, all electronic detonators in the priming area are connected into the priming circuit by using a circuit connecting wire, led out of the priming area and then connected with a priming wire, so that a firing instruction and the transfer of priming energy are realized, and detonators in holes are controlled to be primed.

During construction, the connection between the network connection line and the detonating line is generally achieved by an electrical connection method. In order to ensure the reliable connection quality, the measures adopted during connection are as follows:

1. the connection is reinforced, and the virtual connection is prevented from influencing the working stability of the detonating network;

2. the joints are bound by insulating tapes to prevent exposure and grounding;

3. the explosion wire is pressed by the stone, so that the damage of external disturbance to the joint is prevented, and the explosion instantaneous area is prevented from being pushed to drag the explosion wire (to a certain extent);

4. a buffer section is laid and reserved on the detonating cord and the network connecting line to prevent the circuit from being dragged.

However, problems encountered in actual construction are:

1. the local collapse of the detonation zone at the moment of detonation can pull and drag the line, and the line cannot be separated from the detonator after normal detonation due to a firm connection measure.

2. The detonator belongs to electronic equipment, and is internally provided with an electric storage battery, so that potential safety hazards can be caused by excessive collision.

3. The internal parts of the electronic detonator initiator are easy to damage, the initiator belongs to the information system recorded article and the matched equipment, and the working condition directly determines whether blasting operation can be carried out or not, so that the construction progress is influenced.

4. The equipment is wasted by adopting a buffer section detonating line for preventing dragging.
