Description

Device for diagnosing blasting working state based on blast hole temperature

Technical Field

The utility model relates to a device based on big gun hole temperature diagnosis blasting operating condition is applicable to engineering blasting field, mainly is applied to the monitoring before the blasting and the diagnosis whether normally explode of blasting operation.

Background

In the field of engineering blasting, the detonator is used as the most important detonating material and the most dangerous article, and has the function of generating detonating energy to detonate various explosives, detonating cables and detonating tubes. The safety of workers on site is seriously harmed by the problem of detonator explosion rejection. The detonator is not detonated due to various reasons, and site workers cannot judge the specific positions of the detonator, so that the safety of the site workers is greatly threatened. Therefore, a device for monitoring and diagnosing the blasting working state in the engineering blasting field is needed.

SUMMERY OF THE UTILITY MODEL

The safety problem that the problem leads to is led to the refusal to explode to current engineering blasting field, the utility model provides a device based on big gun hole temperature diagnosis blasting operating condition, dynamic monitoring big gun hole temperature, especially the real-time operational environment temperature of detonator to whether explode the detonator and make the feedback, do the suggestion to the position of refusal to explode the detonator, reduce field work personnel and obtain danger.

The technical scheme of the utility model: the utility model provides a device based on blast hole temperature diagnosis blasting operating condition mainly by including armor K type fine thermocouple, thermocouple compensation wire, temperature transmitter and storage record appearance, its characterized in that: in the blast hole, an armored K-type micro thermocouple is pre-installed, a thermocouple compensation lead of the ground part is combined with a temperature transmitter, and then the whole body is connected with a storage recorder in a networking mode, and the storage recorder is used for monitoring in real time and diagnosing the working condition of the blast hole according to a displayed image.

The utility model has the advantages that:

the working state of blasting operation is monitored and diagnosed by using the device under the engineering blasting environment, dynamic monitoring is carried out based on the temperature of the blast hole and the temperature of the most dangerous article detonator in the blasting operation, the working temperature condition change inside the blast hole is known in real time, and the working state of the blast hole is judged. The safety is added to the blasting operation and the workers on the site. And after the blasting operation is finished, whether the detonator and the explosive are normally detonated is judged by observing the T-T image displayed by the storage recorder. If the signal still exists, the detonator and the explosive are not normally detonated, and meanwhile, the position of the blast hole which does not normally work is prompted for field workers, so that convenience is provided for handling the detonators, the danger of searching the blast hole which is not normally detonated by the workers is eliminated, and the safety is improved. The utility model discloses the device is simple and easy portable, and the installation is simple, and convenient operation can extensively use in engineering blasting field, makes the contribution for the on-the-spot security improves.

Detailed Description

The invention will be further described with reference to the following drawings and specific examples:

the utility model relates to a device based on big gun hole temperature diagnosis blasting operating condition mainly comprises armor K type fine thermocouple 5, thermocouple compensation wire 6, temperature transmitter 7 and storage record appearance 8. Firstly, an armored K-type micro thermocouple 5 and a thermocouple compensation lead 6 are assembled and connected, are installed to the bottom of a blast hole along the direction of the blast hole, are connected with a storage recorder 8 and check whether signals exist or not, and if the signals are not replaced in time. And then, connecting the electronic detonator 4 with the detonator leg wire 3, installing the electronic detonator above the armored K-type micro thermocouple 5, and finally, sequentially filling the ammonium nitrate fuel oil explosive 2 and the blocking part 1. Then the thermocouple compensation lead 6 of the ground part is connected with the temperature transmitter 7, and finally the temperature transmitter 7 is connected with the storage recorder 8 by a lead. After the pin line 3 and the detonation network are networked, the storage recorder 8 is opened and the temperature in the blast hole starts to be monitored.

The temperature in the blast holes is stabilized at about T before blasting is started, after the blasting is finished, whether the images of the blast holes on the storage recorder are consistent with the image in the figure 2 or not is checked in sequence, and if the images are consistent with the image in the figure 2, the temperature in the blast holes is increasedNow obvious jump, jump to T₂When the wire for transmitting the heat signal is damaged, the normal blasting of the blast hole is proved, and the blasting field is in a safe state; if the image with the blast hole is found to be consistent with the image in the figure 3 and is in the abnormal blasting condition I, the electronic detonator has the phenomenon of explosion rejection, the generated explosion does not damage the lead wire for transmitting the heat signal, the blast hole does not work normally, and the blasting site has potential safety hazards. According to the thermocouple of the signal source, confirm its position according to its serial number, and take effective measure to dispel the hidden danger; if the image is identical with the image in the figure 4 and is in the abnormal blasting condition II, the electronic detonator has the phenomenon of explosion rejection, and the temperature in the blast hole has no obvious change T in a short time₂Approximately equal to T, the destructive force generated by the explosion of the peripheral blast holes destroys the wires for transmitting the heat signals, the blast holes do not work normally, the blasting site has potential safety hazards, the positions of the thermocouples are determined according to the numbers of the thermocouples from which the signals are from, and effective measures are taken to eliminate the potential hazards.
