Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor used in a deep water environment with high water pressure and high humidity. Background Art

[0002] The deepwater high-pressure, high-humidity temperature sensor is a measurement device designed specifically for extreme underwater conditions, capable of stable operation in high-pressure, high-humidity environments such as the deep sea. Its rugged housing, reliable sealing system, and corrosion-resistant materials ensure accurate temperature measurement at depths of hundreds or even thousands of meters, despite extreme external water pressure and constant humidity. This provides critical temperature data for applications in marine science research, oil and gas extraction, submarine monitoring, and other fields.

[0003] Currently, temperature sensors are protected by an external shell when used in high-pressure environments, allowing the temperature sensor to detect water temperature in extreme environments. However, the water contains algae and plankton, which will adhere to the outer wall of the temperature sensor. Since some algae and plankton will secrete corrosive liquids, they will accelerate the corrosion of the shell and shorten the service life of the temperature sensor. Therefore, a temperature sensor for use in deep water environments with high water pressure and high humidity has been proposed. Utility Model Content

It has the advantages of reducing the impact of algae and floating matter on the temperature sensor, and solves the problem that these organisms adhere to the outer wall of the temperature sensor. Since some algae and floating matter secrete corrosive liquids, they accelerate the corrosion of the shell and shorten the service life of the temperature sensor.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a temperature sensor for use in a deep-water environment with high water pressure and high humidity, comprising a temperature sensor connector, a temperature detection end, and a signal transmission end, wherein the outer wall of the temperature sensor connector is provided with a sealing protection structure;

[0007] Furthermore, the temperature detection end is located inside the second protective shell, and the signal transmission end is located inside the first protective shell.

[0008] Furthermore, the first sealing ring is located between the first limiting ring and the first protective shell, and the left and right outer walls of the first sealing ring are respectively attached to the right side of the first limiting ring and the left side of the first protective shell; the second sealing ring is located between the second limiting ring and the second protective shell, and the left and right outer walls of the second sealing ring are respectively attached to the left side of the second limiting ring and the right side of the second protective shell.

[0009] Furthermore, the outer wall of the temperature sensor connector is provided with two thread grooves, and the first protective shell and the second protective shell are respectively threadedly connected to the two thread grooves provided on the temperature sensor connector.

[0010] Furthermore, a card slot is provided inside the card seat, and two sides of the elastic card plate are respectively connected to the inside of the two card slots and are adapted in size.

[0011] Furthermore, the temperature detection end is installed on the left side of the temperature sensor connector, and the signal transmission end is installed on the right side of the temperature sensor connector.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] This temperature sensor, which is used in a deep-water environment with high water pressure and high humidity, protects the signal transmission end and the temperature detection end respectively through the first protective shell and the second protective shell. At the same time, the first sealing ring and the second sealing ring respectively seal the interior of the signal transmission end and the temperature detection end to prevent the high water pressure from affecting the sensing element inside the temperature sensor. The first protective sleeve net, the second protective sleeve net, the clamping seat and the elastic clamping plate protect the exterior of the temperature sensor, reduce the impact of algae and floating objects on the temperature sensor, and increase the service life of the temperature sensor.
