The specific implementation mode is as follows:
the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, the description is only for convenience of description and simplification, but the indication or suggestion that the device or element to be referred must have a specific position, be constructed and operated in a specific position, and thus, cannot be understood as a limitation of the present invention. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are not intended to be limiting but rather are to be construed as indicating or implying relative importance.
Furthermore, the terms "horizontal", "vertical" and the like when used in the description of the present invention do not require that the components be absolutely horizontal or hanging, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
The portable dead zone detection and protection device comprises
The sleeve 1, preferably the sleeve 1 is cylindrical in steel, and since the bore 9 is circular in cross-section, the sleeve 1 is cylindrical and is conveniently located in the bore 9.
The foot pedal is positioned at the top end of the sleeve 1, preferably, the foot pedal is made of steel materials and can be round or rectangular.
The stone blocking plate is positioned on the lower surface of the pedal plate and can be inserted into the orifice broken stone 10 at the periphery of the drilled hole 9 to stabilize the orifice broken stone 10 so that the orifice broken stone does not fall into the drilled hole 9 and further protect the laser drill bit;
during exploration, the sleeve 1 is placed in the drill hole 9, the pedal plate is placed on the hole broken stone 10, feet step on the pedal plate, the stone blocking plate is embedded into the hole broken stone 10 under the action of gravity, and after the stone blocking plate is completely embedded into the broken stone, the broken stone is extruded under the stress, so that the stone blocking plate is more stable, and the probability that the broken stone falls into the drill hole 9 is greatly reduced.
