Description

Liquid vibrating sampler

Technical field

The utility model belongs to the sampler of Ocean Surveying, field tests, specifically a kind of liquid vibrating sampler of taking marine bottom sediment.

Background technology

The gravity piston sampler that habitata is used produces impulse force by deadweight, and stopple coupon is crept in the marine bottom sediment, can finish the deep seafloor sampling of several kms of the depth of water, but the restriction that equipment is crept into by weight only is suitable for conventional sediment sampling; Vibrating sampler can be finished the sampling of dense deposits such as sharp sand, iron plate sand and stiff clay, it is big that but electric vibrating sampler cable bears pulling force, be subjected to cable to discharge the restriction of length, usually be controlled at 200 meters of the depth of waters with interior sampling, the air apotheca of pneumatic vibration sampler bears internal pressure, along with sampling depth increases, air apotheca internal gas pressure and seawater pressure difference reduce gradually, be subjected to the restriction of air apotheca intensity, the pneumatic vibration sampler usually also can only be 200 meters of the depth of waters with the sampling of interior waters.

Summary of the invention

The utility model will solve the restriction that existing gravity piston sampler is subjected to weight of equipment, only be suitable for conventional sediment sampling, existing vibrating sampler is subjected to the restriction of parts such as cable own, air apotheca, the more shallow technical matters of sampling water depth provides a kind of darker liquid vibrating sampler in waters of can taking a sample, sample the seabed dense deposit.

In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of liquid vibrating sampler, comprise pouring weight, the stopple coupon that has the edge of a knife of taking a sample, there is the gentle storehouse of liquid vibration device the pouring weight top, liquid vibration device water outlet port is communicated with the gas storehouse, and liquid vibration device water inlet port is communicated with seawater by water intaking valve.

When sampler arrival seabed, there is pressure reduction in gas inside and outside the storehouse, and sampling waters seawater is healed dark pressure reduction more greatly, water intaking valve is opened, the pressure seawater is flowed in the gas storehouse by the liquid vibration device, and the seabed press water makes liquid vibration device vibration sampling as the energy source of liquid vibration device.Sampler can be to the sampling of seabed dense deposit, and not electricity consumption does not have cable, and external pressure is born in the gas storehouse, and voltage endurance capability is strong, can reach 500 meters and even the sampling of two km waters deeply.Pouring weight, gas storehouse have the upright effect of the sampler kept.

The liquid vibration device is made up of oil motor and Vib., and oil motor water inlet port is communicated with seawater by water intaking valve, and oil motor water outlet port is communicated with the gas storehouse.

The power output shaft of oil motor is stretched out to both sides, and the both sides of oil motor are the syndeton Vib. identical with duty respectively.Two Vib. symmetric vibrations of symmetric configuration help sampler vertical sampling work.

The power output shaft of oil motor connects the first vibration hammer axle of eccentric type vibrator, the fixed installation first vibration hammer gear and first vibration hammer on the first vibration hammer axle, the fixed installation second vibration hammer gear and second vibration hammer on second vibrating shaft of eccentric type vibrator, the first vibration hammer axle overlaps with the second vibration hammer axis; Between the first vibration hammer gear and the second vibration hammer gear even number idle pulley is arranged, the first vibration hammer gear is identical with the second vibration hammer gear; First vibration hammer is identical with second vibration hammer, and first vibration hammer and second vibration hammer arrive the highs and lows of rotation simultaneously.Under fluid motor-driven, first vibration hammer and the second vibration hammer constant speed reverse rotation arrive the highs and lows that rotates simultaneously, have offset the wagging that vibration hammer causes, only produce vertical up and down off-centre vibration.

Top, gas storehouse connects the guiding empennage, and the liquid vibration device is above the gas storehouse.Liquid vibration device and gas storehouse upper and lower settings are beneficial to marine stream.

Water intaking valve is above the liquid vibration device.Be convenient to the pressure seawater and enter the liquid vibration device.

The water intaking valve valve core upper end connection sampling wirerope of water intaking valve, when the sampling wirerope hung sampler, water intaking valve was closed, and cut off seawater and intake being communicated with of port with the liquid vibration device; When not having acting force between sampling wirerope and the sampler, water intaking valve is opened, and connects seawater and liquid vibration device water inlet port.Throw in or when slinging sampler, the sampling wirerope hangs sampler, sampler arrives water-bed, and the sampling wirerope is lax, and does not have acting force between the sampler.

The one way pressure-reducing valve that discharges gas storehouse internal pressure is arranged on the gas storehouse.During the sampler of slinging after the sampling, seawater pressure reduces gradually outside the gas storehouse, and one way pressure-reducing valve is discharged release with gas storehouse maritime interior waters and compressed air.

Exhaust-valve discharges water bottom the gas storehouse.Gas storehouse the discharge water emptying of exhaust-valve after to sampling discharges water.

The utility model has the advantages that: seawater is as the energy source of liquid vibration device, and sampler is easy to use, and sampler can not have cable to water-bed dense deposit sampling, and gas storehouse voltage endurance capability is strong, can sample than deepwater field.Without the energy, the sampling cost is low.
