Abstract
The invention discloses a liquid vibrating sampler, which comprises a heavy block and a sampling tube with a sampling blade. A liquid vibrator is arranged above the heavy block; a water outlet of the liquid vibrator is communicated with a gas store and a water inlet of the liquid vibrator is communicated with seawater by an inlet valve. The seawater serves as energy source of the liquid vibrator. The sampler is conveniently used and can sample dense deposit under the water and can take samples in deeper water area. The liquid vibrating sampler uses no energy and has low sampling cost.
Description
Technical field
The invention 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 only is suitable for conventional sediment sampling; The vibration type piston sampler, DDC-Z-1 type vibration type piston sampler for example, adopt and exchange vertical vibrator, utilize high frequency hammering vibration with in the stopple coupon injection sediment, can finish the sampling of the dense deposits such as sharp sand, iron plate sand and stiff clay, but the cable bearing tension is large, is subjected to cable to discharge the restriction of length, usually is controlled at 200 meters of the depth of waters with interior sampling.Chinese utility model patent Granted publication 201340347Y discloses a kind of sampler, utilize the air apotheca on the sampler that the gas vibration source is provided, order about the vibration of gas Vib., can finish the sampling of sharp sand, iron plate sand and stiff clay, the air apotheca bears internal pressure, and along with sampling depth increases, air apotheca internal gas pressure and seawater pressure are poor to be reduced gradually, be subjected to the restriction of air apotheca intensity, this sampler usually 200 meters of the depth of waters with interior sampling.
Summary of the invention
The present invention 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 the 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 present invention takes is: a kind of liquid vibrating sampler, comprise pouring weight, stopple coupon with the sampling edge of a knife, there is the liquid vibration device 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 deeply reach 500 meters and even the sampling of two km waters.Pouring weight, gas storehouse have the upright effect of the sampler kept.
The liquid vibration device is comprised 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 are conducive to sampler vertical sampling work.
The power output shaft of oil motor connects the first vibration hammer axle of eccentric type vibrator, fixed installation the first vibration hammer gear and the first vibration hammer on the first vibration hammer axle, fixed installation the second vibration hammer gear and the second vibration hammer on the second vibrating shaft of eccentric type vibrator, the first vibration hammer axle and the second vibration hammer axle dead in line; 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; The first vibration hammer is identical with the second vibration hammer, and the first vibration hammer and the second vibration hammer arrive the highs and lows of rotation simultaneously.Under fluid motor-driven, the 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 eccentric vibrating.
Top, gas storehouse connects the guiding empennage, and the liquid vibration device is above the gas storehouse.Liquid vibration device and gas storehouse are setting up and down, 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 with gas storehouse maritime interior waters and compressed Bas Discharged release.
1 bottom, the gas storehouse exhaust-valve that discharges water.The exhaust-valve that discharges water discharges water emptying to the gas storehouse after taking a sample.
Advantage of the present invention is: 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.
