[0009] See also Figures 1 to 3 The utility model provides a technical solution: an open-pit mine blasting vibration monitoring and protection device, comprising a metal protective cover 1, the metal protective cover 1 is a cylindrical shell, the lower end of the metal protective cover 1 is connected with a circular vibration-damping rubber ring 2, the lower part of the vibration-damping rubber ring 2 is connected with a metal pad 3, and the metal protective cover 1, the vibration-damping rubber ring 2 and the metal pad 3 are connected as a whole.
[0010] The metal protective cover 1 is buckled on the base 7, and a limit plate 9 is provided on the base 7 to prevent the protective cover from shaking at will. Three buckles 4 are connected to the metal pad 3 around the periphery, and are buckled with the slots 10 on the base 7. The base 7 is connected to a metal grip 5, and a vibration meter slot 8 is provided on the base 7, and a fixed drill bit 6 is connected at the bottom.
[0011] The buckle 4 is fixed on the metal pad, the buckle arm 401 is supported by the bracket 403, and the other end is connected to the spring 402. After pressing, the lower end of the buckle rises, and the metal protective cover can be separated from the base. After loosening, it is fastened by the slot. There are 3 buckles around the metal pad to fix it.
[0012] Working principle: This protection device can effectively protect the vibrometer during blasting and prevent flying stones, gravel and other debris from damaging the vibrometer. Seismic waves can be transmitted to the vibrometer through the fixed rod inserted into the rock, and then detect the blasting vibration. When flying stones hit the metal protective cover, the vibration-damping rubber ring under the protective cover can reduce the vibration to a certain extent, so as to reduce the impact of flying stones on the detection data and protect the vibrometer in the device. Before use, you can use a drill to pre-drill a hole on the rock surface, and then screw the base into the drill hole. If you don't use a drill, you can also hold the metal handle on the base to drill the fixed rod into the rock layer. After fixing the base, put the vibrometer into the slot in the specified direction, and tighten the fixing pillar to clamp the vibrometer. Then cover the metal protective cover, align the buckle on the protective cover with the slot on the base and buckle it. At this point, the monitoring and protection device is installed.
[0013] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
