Description

Technical Field

[0001] The utility model relates to the technical field of blasting vibration monitoring, in particular to a blasting vibration real-time monitoring system. Background Art

[0002] Blasting vibration is the process in which a specific particle of a medium makes a linear or curved reciprocating motion along its equilibrium position caused by a blasting earthquake. Blasting operations are often used in engineering fields such as tunnel excavation, mineral mining, and building demolition. Since blasting operations bring huge impact force and pose a potential threat to surrounding residents, factories, cultural relics, etc., it is necessary to monitor the vibration signals generated during the construction process in real time.

[0003] In order to ensure safe production operations, it is necessary to select key test points on the structures around the construction site to deploy blasting vibration monitoring systems to collect and analyze vibration signals generated by on-site blasting. Therefore, the blasting vibration monitoring device needs to be at the blasting construction site for a long time. The power supply of the blasting vibration monitoring device is generally an external power supply or solar power supply, but when the equipment is in a complex environment and the power supply cannot be replenished in time, the monitoring time of the equipment is greatly shortened, seriously affecting the detection effect. At the same time, due to long-term exposure to the outside world, when encountering rainy weather, rainwater can easily penetrate into the interior of the device, thereby affecting the normal use of the blasting monitoring system. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a blasting vibration real-time monitoring system which can be used outdoors for a long time.

[0005] To this end, the technical solution of the utility model is: a real-time monitoring system for blasting vibration, including a base, a column, a vibration sensor, a data acquisition box and a photovoltaic module, the vibration sensor is fixedly mounted on the base, and assembly holes are arranged around the base; a photovoltaic module is arranged above the column, and the photovoltaic module is a cylindrical structure, which is mounted on the outside of the column; a data acquisition box is installed on the column, and a conical rain cover is arranged above the data acquisition box; a dynamic data acquisition instrument, a 4G communication module, a battery control module, a main battery and a backup battery are arranged in the data acquisition box, the photovoltaic module charges the main battery and the backup battery, and the battery control module controls the power supply of the main battery or the backup battery.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the photovoltaic assembly includes an inner tube, a solar panel and a transparent protective cover, the inner tube is sleeved on the outside of the column, the solar panel is fixed on the outside of the inner tube, and the transparent protective cover is sleeved on the outside of the solar panel.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a plurality of mounting surfaces are arranged on the outer side of the inner cylinder, and the solar panel comprises a plurality of flexible solar sheets or rigid solar panels fixed on each mounting surface.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Set up a main battery and a backup battery in the data collection box. When there is sufficient sunshine, the photovoltaic components charge the main battery and the backup battery. The backup battery is kept fully charged and does not work. Only when the main battery is used up, the backup battery is started to extend the working time of the vibration monitoring system during periods of insufficient sunshine and ensure the accuracy of monitoring.

[0012] 2. Adding an additional conical rain cover above the data collection box can effectively prevent rain from entering the data collection box from the door, data interface and other locations, ensuring that the inside of the data collection box is dry and extending its service life.

[0014] 4. A transparent protective cover is installed on the outside of the photovoltaic module, which does not affect the solar panel from receiving light, but also prevents the solar panel from being eroded by dust and rain, greatly extending the service life of the solar panel.
