Abstract
The present invention relates to a single pipe sediment sampler without boundary disturbance, which structurally comprises a sampling pipe and a supporting device thereof, wherein the upper mouth part of the sampling pipe is provided with a valve device which is a ball valve device capable of opening or closing the pipe mouth under the action of hydrodynamic force, and the valve device is structurally composed of a valve cover and a ball valve in the valve cover; a sealing ring matched with the ball valve is installed in the valve cover in the upper pipe mouth position of the sampling pipe, the ball valve is movably arranged on the sealing ring to form a valve for closing the upper pipe mouth of the sampling pipe. In the present invention, by hermetically matching the ball valve in the ball valve device installed at the upper mouth part of the sampling pipe with the sealing ring on the pipe mouth of the sampling pip, the sampler closes the upper pipe mouth of the sampling pipe when the sampler is pulled upwards after sampling to form a vacuum state in the sampling pipe so that samples in the pipe can not be disturbed and the layer sequence can be kept in the original state.
Description
Technical field
The present invention relates to a kind of sampling pipe device that underwater sediment(s) is sampled.
Background technology
Tubular type sediment (under water) sampling thief is the scientific research apparatus that is widely used in aspect researchs such as environment, ecology and biology, at present designed most of tube sampler all produces the border disturbance when sampling, sample disturbance and sequence are destroyed, and can't collect upper water.CN2591609 discloses a kind of oceanic sediment pressurize sampling apparatus of non-boundary disturbance, this device adopts suitable complex mechanical construction to make sampling pipe form the no disturbance state of sealing after sampling, complex structure not only, the cost height, be difficult to safeguard, and because its structural reason causes the malfunctioning sampling work that causes of mechanical action to fail easily.
Summary of the invention
The underwater sediment(s) interface that the objective of the invention is to propose a kind of collection is undisturbed, simple in structure, and the single tube sediment sampler of reliable in action, non-boundary disturbance with low cost is to overcome the existing problem of above-mentioned existing sampling with single pipe device.
The objective of the invention is to be provided with that a valving realizes by upper oral part at sampling pipe, the concrete structure of this sampling thief comprises sampling pipe and fulcrum arrangement thereof, the infraoral of sampling pipe is equipped with sampling head, said fulcrum arrangement comprises main support plate, fixed mount, weight and gimbal, its sampling pipe is by main support plate support fixation, fixed mount is installed on the main support plate, weight is installed on it, in order to regulate the sinking gravity of sampling thief, thereby regulate sampling pipe to sedimental collection capacity, gimbal is sleeved on the collection tube, and is lifted on the fixed mount by stay cord, uses so that sampling thief keeps plumbness when sinking sampling; The said valving that is installed in the upper oral part of sampling pipe be one can be at the ball-cock device of the closure or openness mouth of pipe under the hydrodynamism, its structure is made of the ball valve in valve pocket and the valve pocket, upper orifice position in sampling pipe in valve pocket is equipped with the O-ring seal that matches with ball valve, ball valve movably places O-ring seal top, forms the closing valve to the upper orifice of sampling pipe.
In the present invention, the ball valve in the ball-cock device of the upper oral part of sampling pipe can sink down into the top of O-ring seal by the weight of self, cooperates the upper orifice sealing with sampling pipe with O-ring seal.When sampling pipe sinks, hydrodynamic force upwards holds up the ball valve of the mouth of pipe and breaks away from O-ring seal, the valve that is the mouth of pipe is opened, water in the sampling pipe can upwards enter valve pocket from the mouth of pipe and outwards be overflowed by the water delivering orifice on valve pocket top and the osculum of valve pocket perisporium, at the valve pocket perisporium osculum is set and can quickens escaping of water; When sampling thief arrive water bottom, reliable natural sinking gravity collect sediment and on swim; When sediment sampler was static, the ball valve in the ball-cock device sank down into O-ring seal top by own wt; When sampling thief is pulled upwardly, under the double action of hydrodynamic force and ball valve gravity, ball valve and O-ring seal are fitted closely, promptly auto-closing mouth of pipe valve, along with the pull-up of sampling pipe, column shaped deposit in the sampling pipe and basic sediment disconnect naturally, sampling pipe separates with water body at last, finishes sampling action, because upper orifice is closed, make and form vacuum in the sampling pipe, thereby sample does not have disturbance and sequence maintains the original state in can holding tube.
The key problem in technology that the present invention becomes a kind of single tube sediment sampler of non-boundary disturbance is mounted in being sealed and matched of O-ring seal on the mouth of pipe of ball valve in the ball-cock device of upper oral part of sampling pipe and sampling pipe, constitute sealing when sampling thief is drawn on after sampling, form the vacuum state in the sampling pipe the sampling pipe upper orifice.Said ball valve is the spheroid of proportion greater than water or seawater, by the material of proportion greater than water or seawater, make as stone material, stainless steel etc., also can be by charging into the material of proportion in the baton round housing, as the spheroid of these ball valves of formation such as metal materials such as lead or mercury greater than water or seawater.
Single tube sediment sampler provided by the present invention, can reach the undisturbed technique effect in sediment interface of collection, sediment that can collect and upper water, the sequence of sample is not damaged, be adapted to the needs of aspect researchs such as environment, ecology, and have advantage simple in structure, with low cost.
