Description
Technical field
The present invention relates to seawater measurement apparatus, specifically, is related to a kind of encapsulation dress of ocean temperature measuring probe housing
Put.
Background technology
In oceanographic survey, ocean temperature is one of most basic marine hydrology parameter, is had for marine environment research
Important function.The research of marine hydrology fine structure, superposed, different water levels the thermogrades on water body border etc.
Deng, it is desirable to temperature transducer has high accuracy and rapid time response, to grasp its changes in distribution rule.In order to ensure thermometric
The rapid time response of sensor, the seal casinghousing of temperature probe need less appearance and size, the conventional quick response in the country
The size of the temperature probe of time constant is generally internal diameter Ф 0.6mm, external diameter Ф 0.8-2mm, length about 40-100mm.Due to surveying
Internal diameter and longer length of the temperature probe with very little, therefore the hermetically sealed of temperature probe becomes very difficult.
Fig. 1 shows the structure of current quick response temperature sensor temperature probe, temperature probe by seal casinghousing 1, draw
Line 2, thermistor 4 and casting glue 3 form.Seal casinghousing 1 is elongate hollow configuration, and one end of seal casinghousing 1 is hatch frame,
The other end is closed structure.Thermistor 4 is placed on the inner tip of seal casinghousing 1, by two ligaments 2 thermistor
4 signal outputs, casting glue 3 are wrapped up thermistor 4 full of inside seal casinghousing 1.
Quick response temperature probe is when making firstly the need of being placed on seal casinghousing 1 with leaded 2 thermistor 4
Inside close to blind end, casting glue 3 is then poured into inside seal casinghousing 1 to be fixed, encapsulate to thermistor 4.Through
The casting glue 3 often used is epoxy glue, and more sticky, mobility is poor, the internal diameter of seal casinghousing 1 be Ф 0.6mm it is elongated in
Hollow structure, therefore pouring into for the casting glue 3 of seal casinghousing 1 becomes extremely difficult.The method used at present is first in temperature-sensitive electricity
Resistance 4 and the applied atop casting glue 3 of lead 2, thermistor 4 and lead 2 are then inserted seal casinghousing from the openend of seal casinghousing 1
Inside 1, casting glue 3 is brought into inside seal casinghousing 1 by thermistor 4 and lead 2, this process repeatedly for three times, completes thermometric
The encapsulation of probe.But because the inside of elongated seal casinghousing 1 be full of air, and one end closing, thermistor 4 and lead 2 are from opening
Hold into fashionable, cause the gas inside seal casinghousing 1 to exclude difficult, therefore after temperature probe encapsulates, inside seal casinghousing 1
Have a large amount of gas residues.Further, since the thermal conductivity ratio of air is relatively low, the air residual around thermistor 4 can be serious
The responsive time constant of temperature probe is influenceed, and the air residual inside seal casinghousing 1 has a strong impact on thermistor 4 and lead 2
Fixation, therefore after encapsulating the temperature probe response time is bigger, fault rate is higher, had a strong impact on temperature probe can
By property.
The content of the invention
For the encapsulation of existing quick response temperature probe, exist and pour into that casting glue is difficult, after encapsulation inside seal casinghousing
There is air residual to cause the problem of responsive time constant is bigger, fault rate is higher, the present invention is proposed quick response thermometric
Probe packaging system, it is intended that extracting the air in vacuum sealing cabin by vavuum pump, pass through and produced inside seal casinghousing
Negative pressure is difficult to pour into, is also easy to produce the problems such as air residual to suck casting glue and then solve casting glue, improves the sound of temperature probe
Between seasonable and reliability.
It is achieved in order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of quick response temperature probe packaging system of the present invention, including vacuum sealing cabin and Vacuum Pumps Station, very

Observe internal state；The upper end cover and bottom end cover in vacuum sealing cabin make by engineering plastics, be easy to alleviator weight and
Temperature probe encapsulation operation；Casting glue hopper is square casting glue hopper, for storing casting glue.
Vacuum Pumps Station is by the first quick connector with vacuum pump group into one end and the vavuum pump of the first quick connector pass through sealing
Pipe screw thread is connected, and the other end is connected with vacuum hose.
The upper end cover in vacuum sealing cabin is by filling block movable part, bolt, intake valve, vacuum meter, the second quick connector, true
Empty valve and mounting seat composition, filling block movable part are sealed by bolt and mounting seat, and filling block movable part can pass through
Handwheel control filling block above it moves up and down；Intake valve, vacuum meter, vacuum valve are connected by sealing pipe screw thread and mounting seat
Connect；Vacuum meter is used for the vacuum for showing vacuum sealing cabin；Second quick connector is threadedly coupled with vacuum valve by seal pipe, the
Two quick connectors are used to quickly connect vavuum pump by vacuum hose.
Filling block movable part by handwheel, stud, stud base, base support block, seal bar, filling block, holding screw,
Limited block, fastening bolt and alignment pin composition；Handwheel is arranged on the top of stud, is attached by nut；Stud passes through spiral shell
Line is connected with stud base；Base support block is used for supporting studs base；Seal bar is located at the lower section of stud, by alignment pin with
Stud connection；Filling block is located at the bottom of seal bar；Limited block is located at the upper lateral part of seal bar.
Quick response temperature probe packaging system involved in the present invention is in use, first the thermistor cleaned
And lead is inserted into inside seal casinghousing from the openend of seal casinghousing so that thermistor reaches the top of seal casinghousing, so
Seal casinghousing is tiltedly placed on afterwards on casting glue hopper inclined-plane, openend is downward.Then casting glue is injected into casting glue hopper, is noted
The casting glue entered did not had the openend of seal casinghousing just, covered the upper end cover in vacuum sealing cabin.Vacuum hose is inserted respectively
Enter the quick connector above vacuum sealing cabin upper end cover and Vacuum Pumps Station, complete the connection of vacuum sealing cabin and Vacuum Pumps Station.Take out
Vacuum meter reading terminates to vacuumize after reaching setting, rotation hand wheel so that filling block moves downward, and filling block submerges embedding
Glue so that embedding glue liquid surface rises, and after embedding glue liquid surface floods seal casinghousing openend, intake valve is slowly opened, by outer
The pressure of portion's air is pressed into casting glue the inside of temperature probe seal casinghousing, completes the encapsulation of temperature probe.The present invention's has
Beneficial effect is realize casting glue in tiny seal casinghousing canned, and the temperature probe response time after encapsulation is small, fault rate is low, carries
The high reliability of temperature probe.
