Technical field
The present invention relates to a kind of sampling bottle unhook releasing device, specifically a kind of pressed cover sampling bottle that makes is finished the sampling bottle unhook releasing device of adopting the hydrodynamic(al) work at depth section.
Background technology
Marine environmental pollution monitoring, seawater physical chemistry and geologic examination in most cases need from target marine site collection water sample.Sometimes need sample successively at different depth, obtain the on-the-spot water body information of gradient profile, to guarantee unitarity, standardization and the analogy of analysis result.Nice gold sampling bottle (Niskin bottle) and other sampling bottles according to its principle improvement, reasonable in design, simple to operate and clean the easy present widely used water sampler that becomes because of it.No matter be that several sampling bottles are placed in sunflower formula hydrophore (Rosette Sampler), still directly dress hangs on the sampling hawser, all utilize the principle of work of its " open-close " or " closing-open-close ", two Ka Gai open when promptly discharging, bottle is in the flushing state, after arrival is scheduled to adopt water depth, is provided release signal or is manually discharged hammer by system, close Ka Gai, realize sampling.
Sunflower formula hydrophore utilizes release hook that the sampling bottle card is covered spacing rope more and hooks, and takes off release hook under stepping motor action, closes under the pulling force effect of Ka Gai bungee or bottle outer spring in sampling bottle; Need not manual intervention during operation, but uncoupling rigging is complicated, and stepping motor is influenced by high pressure, temperature etc. to cause seize and misoperation.Directly dress hangs over the sampling bottle on the sampling hawser, then manyly locates to operate hammer on the quarter Ka Gai is closed, and is therefore more loaded down with trivial details and waste time and energy.
Summary of the invention
At the deficiencies in the prior art, the problem to be solved in the present invention provide a kind of mechanical mechanism and automatically controlled simple in structure, move sampling bottle unhook releasing device accurately, when sampling depth is scheduled in arrival, can automatically-unhookedly close sampling bottle Ka Gai, finish sampling smoothly.
For addressing the above problem, the technical solution used in the present invention is:
Sampling bottle unhook releasing device of the present invention, integral installation is on hydrophore, have bearing pin locating rack, bearing pin and solenoid valve, wherein bearing pin is located in the through hole of bearing pin locating rack, one end of bearing pin and the moving iron core of solenoid valve are connected, the bearing pin locating rack is provided with one and intersects the recess that connects with through hole, and the anchor line (string) that connects sampling bottle Ka Gai is placed on the bearing pin in the indent of bearing pin locating rack.
Described solenoid valve sealing is arranged in the solenoid valve storehouse, and bearing pin is placed through in the solenoid valve storehouse by outer end cap; The solenoid valve storehouse is installed in the control gas-tight silo of hydrophore; Described solenoid valve is full of oil in the storehouse, and outer end cap is provided with opening, and the sealing of oil resistant rubber film is installed; The control line of described solenoid valve by watertight connector be located at the control circuit of control in the gas-tight silo and link to each other; Described bearing pin locating rack, bearing pin and solenoid valve are according to the supporting setting of the quantity of sampling bottle.
The present invention has following beneficial effect and advantage:
1. simple in structure.Sampling bottle unhook releasing device of the present invention need not the complicated mechanical member, and control Driver Circuit is also very simple; Do not use stepping motor, avoided the possibility of misoperation;
2. good sealing effect.The present invention fills with oil in the solenoid valve storehouse, keep the balance of oil pressure and extraneous hydraulic pressure in the solenoid valve storehouse with rubber diaphragm; Water can not brought into the solenoid valve storehouse when bearing pin moves under moving iron core drives, guarantee sealing effectiveness;
3. dependable performance is moved quick, accurate, time saving and energy saving.The solenoid valve energising is moved, can reliably discharge, and closes Ka Gai;
4. stronger applicability is arranged, can carry and the identical pressed cover sampling bottle of Nice gold sampling bottle principle, and not limit its size and volume.
