The receiving container is fixed to the receiving container, the round water level is welded to the receiving container, the micro-pressure sensor and the photoelectric liquid level sensor are connected with the LCD timing and flow display device through a wire, and the micro-pressure sensor, the photoelectric liquid level sensor and the LCD timing and flow display device are fixed to the receiving container. According to the columnar water inflow measuring device for tunnel and mine engineering, precise measurement of columnar water is achieved, and the situation of overlarge errors caused by that fact that effective instruments are insufficient, and measurement personnel adopt an empirical method for estimation and measurement in current measurement of columnar water inflow in a mine or a tunnel is changed.
Description
Technical field
The present invention relates to underground engineering survey device, relate in particular to a kind of tunnel, mine engineering column water yield measurement mechanism.
Background technology
China's underground engineering construction causes such as tunnel, subway, power station, iron ore, colliery of growing up are at present flourish, but prominent water burst accident occurs often, has caused a large amount of casualties and economic loss.This wherein has partly cause is that the monitoring of mine or Tunnel Seepage is not in place, cannot accurately measure crack water yield.
Tunnel column water burst is the important component part of crack, tunnel water burst, and it refers to the water burst that tunnel wall ejects, because the water yield is gushed out compared with being column greatly.For the measurement of tunnel column water yield, domesticly there is no effective accurate measurement instrument device, survey crew adopts empirical method or the estimation of amateur instrument to measure more, and the measuring result error drawing is larger, and therefore domestic still having very large blank aspect the trickle amount accurate measurement instrument device exploitation of tunnel.
Summary of the invention
The present invention is in order to address the above problem, a kind of tunnel, mine engineering column water yield measurement mechanism have been proposed, this device effectively carries out measures of quantization to tunnel, mine engineering column water burst, changed at present in mine or tunnel column water yield are measured, survey crew adopts empirical method estimation to measure to cause the excessive present situation of error owing to lacking effective instrument more.
To achieve these goals, the present invention adopts following technical scheme:
A kind of tunnel, mine engineering column water yield measurement mechanism, comprise and receive bayonet socket, receiving vessel, circular bubble, micropressure sensor, photoelectric liquid level sensor, LCD timing and flow display device; Receive bayonet socket and be fixed on receiving vessel, circular bubble is welded on receiving vessel, and micropressure sensor, photoelectric liquid level sensor and LCD timing are connected by wire with flow display device, and three is fixed on receiving vessel.
Described receiving vessel both sides are screwed respectively jug, and two handles are symmetrical.
Described receiving vessel is provided with 4L, 8L and amounts to two gears.
Described micropressure sensor is screwed in fixed volume columnar water receiving vessel bottom, is connected with LCD timing by wire with flow display device.
Described photoelectric liquid level sensor, has two, is screwed in respectively fixed volume columnar water receiving vessel 4L, 8L scale place, is connected with LCD timing by wire with flow display device.
Beneficial effect of the present invention is:
1. realized the accurate measurement of columnar water, changed at present in mine or tunnel column water yield are measured, survey crew adopts empirical method estimation to measure to cause the excessive present situation of error owing to lacking effective instrument more;
2. adopt micro-pressure and level sensing principle, there is the advantages such as precision is high, waterproof;
3. realized by sensing device and LCD timing and flow display device the full-automation that columnar water is measured;
4. volume is little, is easy to carry;
5. be equipped with circular bubble, can realize levelling function;
6. be applicable to mine, Tunnel Lamp underground works, applied widely.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is structure left view of the present invention;
Fig. 3 is structure vertical view of the present invention;
Wherein 1 columnar water receives bayonet socket, 2 fixed volume columnar water receiving vessels, 3 circular bubbles, 4 handles, 5 photoelectric liquid level sensors, 6 micropressure sensors, 7LCD timing and flow display device.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1-Figure 3, a kind of tunnel, mine engineering column water yield measurement mechanism, receive bayonet socket, 2 fixed volume columnar water receiving vessels, 3 circular bubbles, 4 handles, 5 photoelectric liquid level sensors, 6 micropressure sensors, 7LCD timing and flow display device by 1 columnar water and formed.
Columnar water receives bayonet socket and is connected with fixed volume columnar water receiving vessel, micropressure sensor, photoelectric liquid level sensor and LCD timing are connected by wire with flow display device, and circular bubble, handle, micropressure sensor, photoelectric liquid level sensor and LCD timing and flow display device are connected on fixed volume columnar water receiving vessel.
Circular bubble is fixed on fixed volume columnar water receiving vessel by the mode of welding, and in measuring process, circular bubble keeps the level of instrument, thereby makes measurement result more accurate.
Handle is screwed on fixed volume columnar water receiving vessel, and has two, symmetrical.
Micropressure sensor is screwed in fixed volume columnar water receiving vessel bottom, and explosion-proof, anticorrosion, is connected with LCD timing by wire with flow display device.
Photoelectric liquid level sensor is screwed in fixed volume columnar water receiving vessel 4L, 8L scale place, have 2, be connected with flow display device with LCD timing by wire, tunnel column current are not of uniform size, in the situation that current are less, for saving time, gather 4L water and can measure accurately column water yield, under such condition, it is available that instrument is provided with 2 gears.
LCD timing and flow display device are screwed on fixed volume columnar water receiving vessel, and on it, there is 4L, 8L amounts to 2 gears, with 2 positions of photoelectric liquid level sensor be relation one to one, to select 4L gear as example, produce respectively signal in current contacting container bottom and water level arrival 4L place photoelectric liquid level sensor, LCD timing and flow display device receive the signal from bottom pressure transducer and 4L place photoelectric liquid level sensor, time while recording current contacting container bottom and water level arrival 4L, by mistiming and container 4L volume calculations columnar water flow and be presented on display screen.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection scope of the present invention.
