When a bad geological section is encountered, geological disasters such as water inrush, mud outburst, collapse and the like are easy to occur, and even major safety accidents such as personal casualties, equipment damage and the like are caused. In order to prevent geological disasters and safety accidents in the underground engineering construction process, the method is an effective way to detect the front part of a working face by utilizing the advanced geological forecasting technology.

Artificial sources are largely divided into two categories, namely explosive sources and non-explosive sources. Non-explosive seismic sources are further classified into mechanical impact, gas explosion seismic sources, electric energy seismic sources and the like. The explosion energy of the explosive seismic source is mostly consumed to cause the surrounding rock mass to be crushed or permanently deformed, and only part of the energy forms effective seismic interference. For dry loose rock, the effective energy is very low, and a better seismic wave effect can be obtained only in a water-containing plastic medium. Explosive seismic sources have been gradually replaced in recent years by non-explosive seismic sources. The mechanical impact type seismic source uses a mechanical device to impact the ground or a working surface to form a vibration effect. The excited seismic wave has low frequency, generally within 100Hz, low resolution and large energy consumption. The gas explosion focus belongs to a mechanical device, and is characterized by that the high-pressure gas is pressed into a container, and instantaneously released at outlet to produce strong impact and produce vibration effect. The gas explosion seismic source has the characteristics of high frequency and wide frequency band.

When the position of the high-pressure nozzle 7 needs to be continuously adjusted to enable the high-pressure pulse jet beam to form excitation seismic waves at multiple positions of a working surface of a rock body or a soil body to be excavated so as to improve the detection range of a bad geological body, at the moment, the lifting device 37 enables the movable end of the lifting device 37 to drive the fixing rod 36 to reciprocate up and down, as shown in fig. 9, so that the fixing rod 36 and the sliding sleeve 35 are driven to reciprocate up and down, the sliding sleeve 35 is connected with a sliding block through an elastic resetting mechanism, the sliding block can move along two vertical grooves 30 and an X-shaped groove 31 which are arranged in parallel at the same time of moving, two upper side end parts of the X-shaped groove 31 are communicated with upper side end parts of the two vertical grooves 30, the groove depths of the two upper side end parts of the X-shaped groove 31 are smaller than those of the two vertical grooves 30, two lower side end parts of the X-shaped groove 31 are communicated with lower side end parts of the two vertical grooves 30, and the groove depths of the two lower side end parts of the X-shaped groove 31 are larger than those of the two vertical grooves 30 The depth of the side end, as shown by the arrow in fig. 9, is the moving track of the slider, specifically, when the slider starts moving up, because the two lower ends of the X-shaped groove 31 are connected to the lower ends of the two vertical grooves 30 and the depth of the two lower ends of the X-shaped groove 31 is greater than the depth of the lower ends of the two vertical grooves 30, the slider will only move along the inner bottom wall of the X-shaped groove 31 by the action of the elastic return mechanism, and the depth of the lower end of the X-shaped groove 31 is greater than the depth of the lower end of the vertical groove 30, at this time, the slider will touch and obstruct when moving to the lower end of the vertical groove 30, so that the slider can only move along the X-shaped groove 31 when moving up, and after moving up to the top and starting moving down, because the two upper ends of the X-shaped groove 31 are connected to the upper ends of the two vertical grooves 30 and the depth of the two upper ends of the X-shaped groove 31 is less than the depth of the upper ends of the two vertical grooves 30, at this moment, the upper end part groove of the vertical groove 30 is deeper, then the sliding block only moves downwards along the vertical groove 30, that is, the sliding block moves upwards along the X-shaped groove 31, and the sliding block moves downwards along the vertical groove 30, then the sliding sleeve 35 moves along the track shown in fig. 9 along with the sliding block, finally the bottom plate 1 and the high-pressure nozzle 7 are driven to move upwards in an inclined manner and move downwards in a vertical manner, and finally the high-pressure pulse jet beams can form excitation seismic waves at multiple positions of the rock body or soil body working surface to be excavated so as to improve the detection range of the bad geological body.

In a specific embodiment of the present invention, the elastic resetting mechanism includes a cylinder 32, a moving rod 33 is movably inserted into one end of the cylinder 32 facing the vertical plate 29, the slider is fixedly mounted on the moving rod 33, the cylinder 32 is connected to the vertical plate 29 through a third elastic resetting member 34, and preferably, the third elastic resetting member 34 is a compression spring.

In the embodiment of the present invention, a counterweight 28 is disposed on a side of the base 26 away from the supporting rod 25, so as to ensure the stability of the embodiment.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
