Description

A kind of petal cutter head
Technical field
The utility model relates to a kind of ocean engineering field of mechanical technique, relates in particular to a kind of petal cutter head for marine gravity sampling piston device.
Background technology
Marine gravity sampling piston device is the conventional equipment of marine sediment column sampling at present.Marine gravity sampling piston device is relatively simple for structure, comprises the edge of a knife, mouth of pipe envelope, sample pipe, delivery system, carries pipe weight and piston etc.Carry pipe weight and sample pipe flange and connect jail, the edge of a knife, mouth of pipe envelope are arranged on sample pipe lower end, and piston is placed on lower end in the sample pipe, and hanger rope is got certain position and clipped by the clamping plate of delivery system, and remaining section is connected with piston with the sample pipe is inner through carrying the pipe weight.Its principle of work is: when sample collector is transferred to while apart from seabed, also having certain distance, the attached weight of delivery system makes it first the end, and the lever lack of equilibrium discharges and carries pipe weight and sample pipe etc., make its " freedom " landing, sample collector rely on own wt by the injection of sample pipe in sediment; Piston is stopped landing by the hanger rope tractive simultaneously, and the sample pipe continues injection and make piston produce suction force; When the sample pipe finish is promoted in injection, mouth of pipe envelope is mouth of pipe sealing, and prevents from managing interior sample together with the suction force of piston and loses.Obviously, the fundamental driving force of marine gravity sampling piston device sampling is the weight of himself, and the weight that increases merely sample collector is very easy to, and sample collector weight is subject to the restriction of the conditions such as research vessel, lifting appliance in use.Therefore, the major technique content of marine gravity sampling piston device is embodied on its sampling efficiency, utilizes limited own wt to obtain long as far as possible and complete column core sample.This will ask sample collector transferring, when undershoot, injection, reduce the resistance that water and sediment produces as far as possible, and make sediment and enter as much as possible and intactly the sample pipe and do not lose.
Mouth of pipe envelope and the piston of marine gravity sampling piston device are the critical components that affects sampling efficiency.Mouth of pipe envelope is arranged on sample pipe lower end, and its effect is to enter the pipe rear enclosed sample pipe lower end mouth of pipe at sediment sample, prevents the sample loss.Its ideal functionality should be: when sample collector undershoot and the injection of sample pipe, open fully, water and sediment does not produce resistance; When promoting, it can seal the mouth of pipe fully, prevents the sample loss.The mouth of pipe envelope of existing marine gravity sampling piston device has petal type and edge of a knife association type etc.Because edge of a knife association type can not seal the mouth of pipe fully, the existing petal type that still adopts.Petal type mouth of pipe envelope, is fixed on lower end in the sample pipe by the edge of a knife upward by tip and have certain elastomeric several pieces metal petals and form.Obtain long column core require the intensity of metal petal and elasticity large, and the intensity of petal and elasticity are large, the resistance produced during the injection of sample pipe is just large, just large to the disturbance of upper layer sediment sample; If intensity and the elasticity of metal petal are little, petal can be oppressed and reverse by managed interior sediment, thereby makes mouth of pipe envelope fully ineffective.
