Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2, but the air-tight water-sampling bottle of bottle cap floating self-locking of the present utility model, comprise sounding bottle cylindrical shell 4, two stop valves 5 and pressure balance chamber 6 are installed on the cylindrical shell 4, piston 7 is arranged in the pressure balance chamber 6, the two ends of cylindrical shell 4 have upper bottle cover 8 and lower bottle cap 9 respectively, on upper bottle cover 8 and the lower bottle cap 9 O RunddichtringO 10 is housed respectively, 11, be provided with first extension spring 12 in the cylindrical shell, the two ends of first extension spring 12 link to each other with the inboard of upper bottle cover 8 with lower bottle cap 9 respectively, it is characterized in that be equipped with axisymmetrically on the cylindrical shell a pair of have on the self-locking body 3 of self-locking body 3-1 and following self-locking body 3-2, on, following self-locking body 3-1,3-2 is processed with the first cone I and the second cone II respectively, upper bottle cover 8 connects by pin 13 goes up self-locking clamp 1, lower bottle cap 9 connects self-locking clamp 2 down by pin 14, between two jig arm of last self-locking clamp 1 second extension spring 15 is housed, between two jig arm of following self-locking clamp 2 the 3rd extension spring 16 is housed, one end of two first guide fingers 17 is connected on the self-locking body 3-1 axisymmetrically, the other end of two first guide fingers 17 is a free end, pass through the pair of holes 19 on the upper bottle cover 8 respectively, one end of two second guide fingers 18 is connected on the self-locking body 3-2 axisymmetrically, the other end of two second guide fingers 18 is a free end, pass through the pair of holes 20 on the lower bottle cap 9 respectively, fixed connecting plate 21 on the cylindrical shell 4, on, lower supporting plate 22,23 are separately fixed at the two ends of web joint 21, square hole 24 is arranged on the upper backup pad, top sheave 26 is equipped with in the upper backup pad end, first rigid cord 28 is walked around top sheave 26, pass the square hole 24 of upper backup pad, the one end is connected with upper bottle cover 8, the other end is the link with the releasing mechanism hook of the dark measuring instrument of thermohaline, square hole 25 is arranged on the lower supporting plate, lower sheave 27 is equipped with in the lower supporting plate end, second rigid cord 29 is walked around lower sheave 27, pass the square hole 25 on the lower supporting plate, the one end is connected with lower bottle cap 9, and the other end is the link with the releasing mechanism hook of the dark measuring instrument of thermohaline.
Before the sampling (seeing Fig. 1, Fig. 2), two stop valves 5 are closed, and first rigid cord 28, second rigid cord 29 are strained upper and lower bottle cap 8,9 respectively, and hang on the hook of releasing mechanism of the dark measuring instrument of thermohaline.The jig arm of upper and lower self-locking clamp slightly contacts with the first cone I of upper and lower self-locking body respectively, and upper and lower bottle cap is in the state of opening, and the piston 7 of pressure balance chamber is in the position of the most close sounding bottle cylindrical shell simultaneously.
(see figure 3) during sampling, the hook of the releasing mechanism of the dark measuring instrument of thermohaline is decontroled first, second rigid cord, the effect lower cover of first extension spring of upper and lower bottle cap in cylindrical shell is to the sounding bottle cylindrical shell, upper and lower self-locking clamp jig arm overcomes the effect of second, third extension spring 15,16 respectively simultaneously, open laterally, when bottle cap is built cylindrical shell, upper and lower self-locking clamp jig arm rotates and clamps the second cone II (see figure 4) of upper and lower self-locking body respectively around pin 13,14 under the effect of second, third extension spring.When inside and outside the bottle pressure difference being arranged, last lower bottle cap has the movement tendency of being washed open along the sounding bottle tubular axis, this moment upper and lower self-locking clamp jig arm be subjected to upper and lower self-locking body perpendicular to the pressure of the bus of the second cone II with along the friction force of bus, maximum static friction force and pressure are the clamping direction of jig arm to the direction of the resultant moment of the rotation center of jig arm, jig arm can not be released, thereby upper and lower bottle cap is in self-locking state.In order to make the self-locking effect safe more, the friction factor of the second cone II and jig arm is the bigger the better, and friction factor is more than or equal to 0.15 usually, and for the ease of building bottle cap, the friction factor of the first cone I and jig arm is the smaller the better.
Sampling back (see figure 5), but the air-tight water-sampling bottle of bottle cap floating self-locking is got back on the deck, finish after the experimental analysis, operating personnel outwards rotate to extreme position with upper and lower self-locking clamp jig arm, under the effect of second, third extension spring 8,9 and be in open configuration.
