Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, specifically to a sensor fixing structure. Background Technology

[0002] The threaded fixed temperature sensor (HSLW23) is an industrial temperature measurement device primarily used for monitoring the temperature of gases and liquids within pipelines. It can also measure air temperature, oil temperature, and object surface temperature. Its applications cover continuous temperature monitoring needs in industrial environments.

[0003] Existing threaded temperature sensors, such as the PT100 fixed thread temperature sensor, directly use threaded mounting in measurement environments. However, this direct threaded mounting method presents several drawbacks: 1. In harsh environments, the lack of a sealing structure results in insufficient corrosion and dust protection internally, impacting the sensor's lifespan; 2. For temperature detection installation on different pipelines with varying thread diameters, the existing threaded fixed temperature sensor model is fixed, making it unsuitable for installation on a wider range of pipelines, thus limiting its use and reducing efficiency; 3. The fixed installation method between the temperature sensor and the threaded structure restricts its application in various environments, leading to installation difficulties and low adaptability.

[0004] Therefore, a sensor mounting structure is needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a sensor fixing structure to solve the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sensor fixing structure, comprising a protective tube installed on a temperature detection pipeline, the protective tube being inserted into the temperature detection pipeline and installed via a flange base, with the flange bases being sealed together; a movable retaining sleeve thread is threaded onto the upper part of the protective tube at the flange base, the movable retaining sleeve thread being sealed and abutting against the end of the protective tube; a temperature measuring tube is fitted inside the movable retaining sleeve thread and the protective tube, the temperature measuring tube being sealed and threaded with the movable retaining sleeve thread; and a junction box is set at the top of the temperature measuring tube.

[0007] Preferably, the movable ferrule thread includes a threaded sleeve, the outside of which is set as nut one, and the inside of which is set as a sealing ring plate. The sealing ring plate is sealed and abuts against the top of the protective tube. The threaded sleeve above the sealing ring plate has thread one inside, and the threaded sleeve below the sealing ring plate has thread two inside. Thread one is threaded to the temperature measuring tube, and thread two is threaded to the protective tube.

[0012] In summary, this utility model provides a sensor fixing structure. This patent adopts a method of pre-setting a flange base at the opening of the pipeline, inserting the protective tube into the pipeline, and setting a flange base on the protective tube. By installing between the flange bases and setting a sealing ring two between the flange bases, a sealed installation between the protective tube and the pipeline can be achieved. By using the flange base installation method, the protective tube can perform temperature detection on different pipelines, thus reducing limitations.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown:

[0023] This utility model is a sensor fixing structure, which aims to solve the problem of poor sealing performance of existing threaded installation structures. Because the temperature sensor has a fixed model at the factory, it is directly installed on the pipeline by thread, which limits the number of pipelines that can be used and causes the temperature sensor to be used in a limited way. The threaded structure and the temperature sensor are set as an integrated structure, which results in fewer pipelines that can be used and a large limitation in the temperature measurement range, making it impossible to use on multiple devices.

[0024] The structure adopted by this utility model patent includes a protective tube 1 installed on a temperature detection pipeline. The protective tube 1 is inserted into the temperature detection pipeline and installed through a flange base 2, with the flange base 2 being sealed together. The protective tube 1 on the upper part of the flange base 2 is threaded with a movable retainer thread 3, which is sealed and abutted against the end of the protective tube 1. A temperature measuring tube 4 is installed inside the movable retainer thread 3 and the protective tube 1, and the temperature measuring tube 4 is sealed and threaded with the movable retainer thread 3. The top of the temperature measuring tube 4 is set as a junction box 5.

[0025] The protective pipe 1 is inserted into the pipe by pre-setting a flange base 2 at the pipe opening and installing the flange base 2 on the protective pipe 1. The protective pipe 1 and the pipe are sealed by installing the flange base 2 and setting a sealing ring 15 between the flange base 2. By using the flange base 2 installation method, the protective pipe 1 can be used for temperature detection on different pipes, with minimal limitations.

[0026] The upper part of the protective tube 1 adopts a movable ferrule thread 3. The movable ferrule thread 3 is sleeved with the inside of the protective tube 1 to install the temperature measuring tube 4. After the temperature measuring tube 4 is sleeved and installed, it is installed with the movable ferrule thread 3. The temperature sensor can be adapted to be installed on the pipeline through the movable ferrule thread 3, so as to improve the utilization rate of the temperature sensor. The top of the temperature measuring tube 4 is set as a junction box 5 for collecting and utilizing temperature detection data.

[0027] In at least one embodiment, the movable sleeve thread 3 includes a threaded sleeve 6, the outside of which is configured as a nut 21, and the inside of which is configured as a sealing ring 7. The sealing ring 7 is sealed and abuts against the top end of the protective tube 1. The threaded sleeve 6 above the sealing ring 7 has a thread 11 inside, and the threaded sleeve 6 below the sealing ring 7 has a thread 12 inside. Thread 11 is threadedly installed with the temperature measuring tube 4, and thread 12 is threadedly installed with the protective tube 1.

[0028] To enable the temperature sensor to be adapted for installation on different pipes and to detect temperatures at different limits, a movable retainer thread 3 is added between the temperature measuring tube 4 and the protective tube 1. The threaded sleeve 6 on the movable retainer thread 3 has two different inner diameters: thread 11 and thread 12. Thread 11 is adapted to be installed on the temperature measuring tube 4, and thread 12 is adapted to be installed on the protective tube 1. This allows the temperature sensor to be adapted for installation on different pipes and to detect temperatures at different limits, improving the use of the temperature sensor in different environments and reducing its limitations.

[0029] In at least one embodiment, by providing a sealing ring 13 between the sealing ring 7 and the top end of the protective tube 1, the installation sealing between the protective tube 1 and the threaded ferrule 3 is improved, and corrosion, dust and other factors that affect the service life of the temperature sensor are avoided.

[0030] In at least one embodiment, by creating a threaded third 14 in the protective tube 1, and threaded third 14 and threaded second 12, the movable ferrule thread 3 is adapted to be installed between the protective tube 1 and the temperature measuring tube 4, thereby enabling the adaptation to install different temperature measuring tubes 4 for detecting the temperature of different pipes.

[0031] In at least one embodiment, in order to adapt to the installation of different temperature measuring tubes 4 and to adapt to the installation of protective tubes 1 installed on different pipelines, the structure is as follows: the inner diameter of thread 11 is smaller than the inner diameter of thread 12.

[0032] In at least one embodiment, to improve installation sealing and provide corrosion and dust protection, a sealing ring 25 is provided between the flange bases 2 to seal the flange bases 2 during installation.

[0033] In at least one embodiment, in order to achieve the fitting and installation of the temperature measuring tube 4 with the thread 3 of the movable ferrule, and at the same time, to achieve the purpose of corrosion and dust prevention by using a sealed structure, the structure adopted is as follows: the temperature measuring tube 4 has a thread 17, the thread 17 is threaded with the thread 11, and the two are sealed by a sealing ring 16.

[0034] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
