Abstract
The utility model provides a seismic wave detector, in particular to a seismic source trigger device of a seismic wave detector for a coal mine, comprising a cover, a gravity hammer, a spring and a shell, wherein the upper part and the bottom of the shell are respectively provided with a cavity; the gravity hammer is arranged in the cavity at the upper part; the spring is sleeved on the outer wall of the gravity hammer; the upper part of the gravity hammer is provided with a protrusion which slightly extends outwards to butt against the spring; the cavity at the bottom of the shell is a device cavity; and the cover is fixed above the cavity at the upper part of the shell. The utility model is not influenced by the geologic property of the detected surface, and also does not generate stronger sound wave for external interference.
Description
[technical field]
The utility model relates to mining geology detecting instrument, particularly a kind of mine seismic survey instrument.
[background technology]
The seismic survey technology is one of main method of geophysical exploration, also is one of mining geologic prospecting important means.Artificial excitation's seismic wave is propagated in underground different medium, can reflect the different velocities of wave and the underground structure of density interface, and the distribution situation of the discrepant anomalous body of country rock.Pass through instrument, can detect mining areas of mine and tunnel and survey contents such as the form in tomography, karst collapse col umn, goaf, trend, coverage and top end seam thickness, wall rock loosening ring, for the geologic anomaly that occurs in the mining production run provides promptly and accurately Prediction Parameters.Traditional seismic survey mode is that piezo or microswitch directly are fixed on the focus such as "painted-face" character in opera, because lateral wall, the base plate of mine, mine face surface geology different in kind such as meet head on, the influential effect that "painted-face" character in opera impacts triggering is bigger, as on loose surface, impacting, trigger weak effect, on hard surface, impact, trigger effective, trigger effect for improving, place sheet metal on the hammer point of being everlasting and trigger effect, but the hammering sheet metal often disturbs with stronger sound wave with reinforcement.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of and can meets mining seismic survey instrument focus flip flop equipment requirement safe in utilization, that can reliably trigger under the mine.
The utility model is achieved in that a kind of mining seismic survey instrument focus flip flop equipment, described focus flip flop equipment is made of lid, gravity drop hammer, spring, shell, the top and the bottom of described shell are respectively equipped with cavity, in the cavity on top gravity drop hammer is housed, be with spring on the outer wall of described gravity drop hammer, the top of gravity drop hammer is provided with slightly outward extending projection and withstands spring, and the bottom cavity of described shell is a device cavity, and described lid is fixed on the upper cavity top of shell.
Piezo or microswitch are installed in the described device cavity.
Be equipped with some corresponding screw holes position on described shell and the lid, by screw with shell and lid fixedly on the focus.
Use in the described device cavity with the embedding of sealing silica gel, piezo of placing in the device cavity or microswitch have cable to connect.
Advantage of the present utility model is as follows: focus flip flop equipment of the present utility model directly is fixed on the focus such as "painted-face" character in opera, when "painted-face" character in opera impacts lateral wall, the base plate of mine, mine face such as meet head on, when producing seismic wave, install built-in gravity drop hammer and overcome spring pressure, impact the bottom of the cavity of shell upper, excite the piezo of installing in the device cavity of outer casing bottom to produce trigger voltage, or gravity drop hammer pressing microswitch produce trigger pip.Compared with prior art, the utility model is at gravity drop hammer of the inner installation of device, usually under the effect of spring, do not produce triggering, when the "painted-face" character in opera focus impacts any surface, in the moment that "painted-face" character in opera stops, because action of inertia, built-in gravity drop hammer overcomes spring pressure, impact the bottom of the cavity of shell upper, excite piezo to produce trigger action voltage or gravity drop hammer pressing microswitch generation trigger pip.This gravity drop hammer impacts the mode of the upper cavity bottom of shell, neither can be detected surperficial geology property effect, also can not produce stronger sound wave the outside is produced interference.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the schematic cross-section of the general structure of the utility model focus flip flop equipment.
Fig. 2 is the decomposing schematic representation of the general structure of the utility model focus flip flop equipment.
[embodiment]
See also Fig. 1 and Fig. 2, a kind of mining seismic survey instrument focus flip flop equipment, described focus flip flop equipment is made of lid 1, gravity drop hammer 2, spring 3, shell 4, the top and the bottom of described shell 4 are respectively equipped with cavity, in the cavity 41 on top gravity drop hammer 2 is housed, be arranged with spring 3 on the outer wall of described gravity drop hammer 2, the top of gravity drop hammer 2 is provided with slightly outward extending protruding 21, and withstands spring 3.The bottom cavity of described shell 4 is a device cavity 42, in this device cavity 42 piezo or microswitch (not shown) is installed.Be equipped with some corresponding screw holes position 43 on described shell 4 and the lid 1, cover the upper cavity 41 of shell 4 at lid 1 after, by screw whole focus flip flop equipment is locked on the focus such as being installed in "painted-face" character in opera, available sealing silica gel embedding in the described device cavity 42, piezo of placing in the device cavity 42 or microswitch have cable to connect, and also are provided with through wires hole 44 on the sidewall of the device cavity 42 of the bottom of shell 4.
The use principle of described focus flip flop equipment is as follows:
Under the normality, because gravity drop hammer 2 by under lid 1 and the spring 3 acting in conjunction power, is fixed in the shell 4, even flip flop equipment rocks, gravity drop hammer 2 can not produce displacement yet.
When being fixed on the focus such as "painted-face" character in opera when the focus flip flop equipment, "painted-face" character in opera impacts any object, in the moment that "painted-face" character in opera stops, because action of inertia, built-in gravity drop hammer 2 overcomes spring 3 pressure, move on, can impact upper cavity 41 bottoms of shell 4, and the device cavity 42 of shell 4 is interior because piezo or microswitch have been installed, at this time, gravity drop hammer will trigger device chamber 42 interior piezo of installing produce trigger action voltage, or the microswitches generation trigger pip of installing in the gravity drop hammer 2 pressing device cavities 42, finishes the workflow of focus flip flop equipment.
This gravity drop hammer 2 impacts the mode of upper cavity 41 bottoms of shell 4, neither can be detected surperficial geology property effect, also can not produce stronger sound wave the outside is produced interference.
