Abstract
The invention discloses a rapid-response temperature-measuring probe packaging apparatus which comprises a vacuum sealed cabin and a vacuum pump station. The vacuum sealed cabin is composed of an upper end cover, a cylindrical structural sealed cabin, a support column, a lower end cover and a square casting glue trough. The upper end cover is composed of a filling block moving part, a bolt, an inlet valve, a vacuum meter, a quick connector, a vacuum valve and an installing seat. The vacuum pump station is composed of a vacuum pump and a quick connector. When the rapid-response temperature-measuring probe packaging apparatus is in use, a temperature-measuring probe sealing housing provided with a thermistor is placed on the inclined plane of the casting glue trough in an oblique way with the opening end directed downwards. Casting glue is injected into the casting glue trough which is then covered by the upper end cover. A vacuum rubber tube is adopted to connect the vacuum sealed cabin and the vacuum pump station. After vacuum pumping is finished, a hand wheel is rotated and a filling block is moved downwards so that the casting glue liquid level is enabled to immerse the opening end of the temperature-measuring probe housing. Then the inlet valve is slowly opened. The packaging of the rapid-response temperature-measuring probe housing is thus achieved. Casting glue pouring in small sealed housings is further realized.
Description
Technical field
The present invention relates to seawater measurement mechanism, specifically, relate to a kind of packaging system of ocean temperature measuring sonde housing.
Background technology
In oceanographic survey, ocean temperature is one of the most basic marine hydrology parameter, has vital role for marine environment research.The research of marine hydrology microtexture, thermograde of mutually stacked, the different water levels on such as water body border etc., requires that temperature probe has high precision and rapid time response, to grasp its changes in distribution rule.In order to ensure the rapid time response of temperature probe, the seal casinghousing of temperature probe needs less physical dimension, the size of the temperature probe of domestic conventional fast response time constant is generally internal diameter Ф 0.6mm, and external diameter Ф 0.8-2mm, length is about 40-100mm.Because temperature probe has very little internal diameter and longer length, therefore the hermetically sealed of temperature probe becomes very difficult.
Fig. 1 shows the structure of response temperature sensor temperature probe fast at present, and temperature probe is made up of seal casinghousing 1, lead-in wire 2, thermistor 4 and casting glue 3.Seal casinghousing 1 is elongated hollow structure, and one end of seal casinghousing 1 is hatch frame, and 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 is exported, and it is inner that casting glue 3 is full of seal casinghousing 1, wraps up thermistor 4.
First quick response temperature probe needs the thermistor 4 of band leaded 2 to be placed on the inside of seal casinghousing 1 near blind end when making, then pour into casting glue 3 in seal casinghousing 1 inside and be fixed thermistor 4, encapsulate.The casting glue 3 of frequent use is epoxy glue, and compare thickness, mobility is poor, and the internal diameter of seal casinghousing 1 is the elongated hollow structure of Ф 0.6mm, and therefore the pouring into of casting glue 3 of seal casinghousing 1 becomes very difficult.The method of current use is first at thermistor 4 and lead-in wire 2 applied atop casting glues 3, then thermistor 4 and lead-in wire 2 are inserted seal casinghousing 1 from seal casinghousing 1 openend inner, by thermistor 4 and lead-in wire 2, casting glue 3 is brought into seal casinghousing 1 inner, this process three times repeatedly, completes the encapsulation of temperature probe.But because elongated seal casinghousing 1 inside is full of air, and one end is closed, when thermistor 4 and lead-in wire 2 enter from openend, cause the air scavenge difficulty of seal casinghousing 1 inside, therefore, after temperature probe encapsulation, seal casinghousing 1 inside has a large amount of gas residue.In addition, because the coefficient of heat conductivity of air is lower, thermistor 4 ambient air remains the responsive time constant that can have a strong impact on temperature probe, and the air residual of seal casinghousing 1 inside has a strong impact on the fixing of thermistor 4 and lead-in wire 2, therefore the temperature probe response time after encapsulation is larger, failure rate is higher, has had a strong impact on the reliability of temperature probe.
