This technology realizes the integrated operation mode of production, transportation and blasting of civil explosives. Compared with packaged finished explosives, it has the advantages of high mechanization, high charging efficiency, low labor intensity and improved safety of explosives during transportation and use.

[0003] With the promotion of on-site mixed explosive technology, the development of on-site mixed technology of latex matrix "centralized preparation, remote distribution" has also put forward corresponding requirements for the quality of latex matrix: the probability of explosion of latex matrix increases when heated; if the water content of latex matrix is ​​high, the matrix will explode when heated, and when the water content is 15% to 18%, the matrix does not undergo the fuel deflagration to detonation (DDT) process when heated. Therefore, it is necessary to configure explosion-proof safety devices for latex matrix mixed vehicles. However, most of the explosion-proof safety devices for latex matrix mixed vehicles are currently difficult to fully monitor the temperature and water content of the loaded latex matrix. Therefore, a new explosion-proof safety device for latex matrix mixed vehicles is urgently needed to provide an effective solution to the defects of the existing technology. Utility Model Content

[0028] Working principle of this embodiment:

[0029] In the present embodiment, the plug-in monitoring probe 3 is installed on the mounting hole seat 2 on the latex matrix mixing vehicle material tank in a detachable manner, ensuring direct monitoring of the latex matrix. The core part of the probe is a long U-shaped rod 4, on which a plurality of temperature sensors 7 and moisture content sensors are installed at equal distances. The moisture content sensor is composed of an infrared emitting end 5 and an infrared receiving end 6, which are respectively installed on the inner walls of both sides of the long U-shaped rod 4 to form an effective monitoring of the moisture content of the latex matrix. When the latex matrix is ​​within the monitoring range of the long U-shaped rod 4, the temperature sensor 7 measures the temperature of the matrix in real time, and the infrared ray emitted by the infrared emitting end 5 passes through the latex matrix and is received by the infrared receiving end 6, and the moisture content of the latex matrix is ​​determined by measuring the attenuation degree of the infrared ray. The sealing structure between the plug-in monitoring probe 3 and the mounting hole seat 2 ensures the sealing and safety during the monitoring process.

[0030] This embodiment realizes all-round real-time monitoring of the temperature and water content of the latex matrix through multiple temperature sensors 7 and moisture content sensors on the plug-in monitoring probe 3, effectively solving the problem that it is difficult to fully monitor in the prior art. During installation, the long U-shaped rod 4 is evenly distributed in the material tank, and the long U-shaped rod 4 runs through the internal space of the material tank, thereby realizing comprehensive monitoring of the latex matrix in the material tank. Real-time monitoring of the temperature and water content of the latex matrix can timely issue an alarm when the matrix is ​​heated or the water content is too high, prevent the occurrence of explosion accidents, and significantly improve the safety of the latex matrix mixing vehicle during transportation and use. The plug-in monitoring probe 3 has a simple structure and can be easily installed on different latex matrix mixing vehicle material tanks. It has strong adaptability and is easy to promote and apply.

[0031] This embodiment effectively prevents leakage of the latex matrix through the double sealing design of the end face sealing ring 17 and the inner ring sealing ring 19, thereby improving the safety during the monitoring process. The plug-in monitoring probe 3 is threadedly connected to the mounting hole seat 2 through the screw rod 9, thereby realizing a quick and easy installation and disassembly process and reducing the maintenance cost.
