Description

Sampling bottle unhook releasing device

Technical field

The utility model relates to a kind of sampling bottle unhook releasing device, and 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.

The utility model content

At the deficiencies in the prior art, problem to be solved in the utility model 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 adopted in the utility model is:

The utility model sampling bottle unhook releasing device, 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 utlity model has following beneficial effect and advantage:

1. simple in structure.The utility model sampling bottle unhook releasing device 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 utility model is filled 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.

Embodiment

Shown in Fig. 1,2,3A, 3B, 4, present embodiment is example with the quadruplet, the unhook releasing means integral installation of every cover sampling bottle is on hydrophore, have bearing pin locating rack 9, bearing pin 11 and solenoid valve 7, wherein bearing pin 11 is located in the through hole of bearing pin locating rack 9, one end of bearing pin 11 and the moving iron core 21 of solenoid valve 7 are connected, and bearing pin locating rack 9 is provided with one and intersects the recess 9a that connects with through hole, and the width of recess 9a is more than or equal to the stroke of electromagnetism valve actuation iron core.

Sampling bottle 4 can be selected present widely used Nice gold sampling bottle for use, or the similar pressed cover sampling bottle of other principle of work.Sampling bottle 4 is fixed on control gas-tight silo 1 exterior circumferential of the withstand voltage hydrophore of cylindric waterproof.The bungee 3 that the enough intensity of one rhizopodium is arranged in the sampling bottle 4, the card that is connected at sampling bottle 4 both ends covers 2.Two cards cover and all connect anchor line (string) 6 (present embodiment is a nylon monofilament) on 2, and wherein the nylon monofilament end of an end Ka Gai is a link 5, and the nylon monofilament end of other end Ka Gai is knotted into circle cover 8.Adopt water conservancy project when doing, sampling bottle card lid 2 is opened, the circle cover 8 of nylon monofilament end passes link 5, recess 9a place at the bearing pin locating rack, be enclosed within on the bearing pin 11, bearing pin 11 is placed through in the solenoid valve storehouse 14 by outer end cap 12, and the moving iron core 21 by bolt and solenoid valve 7 is fixing, and sampling bottle 4 is that to open attitude in place thus.

In control gas-tight silo 1 one ends, control gas-tight silo 1 inner support 15 is fixed in the inner in solenoid valve storehouse 14 to 14 outer ends, solenoid valve storehouse with bolt.Outer end cap 12 is fixed in 14 outer ends, solenoid valve storehouse; Bearing pin locating rack 9 with screw retention on outer end cap 12.Outer end cap 12 is a toroidal, and outer end cap 12 is a toroidal, its central edge of opening close installation rubber diaphragm 10.Annotate mineral oil in the solenoid valve storehouse 14,, keep oil pressure and extraneous hydraulic balance in the storehouse with rubber diaphragm 10 (oil resistant rubber) sealing.Mainly contain four solenoid valves 7 and a watertight connector 13 in the solenoid valve storehouse 14, watertight connector 13 is five cores, and wherein a core is the power supply common port of four solenoid valves 7; Four-core connects the power input of each solenoid valve 7 respectively in addition.Watertight connector 13 1 ends are installed in the solenoid valve storehouse 14, and the other end stretches into control gas-tight silo 1, and corresponding power lead is connected on the control circuit board 17.
