Description

Technical Field

[0001] The utility model relates to the technical field of thermometers, in particular to a thermometer installation sleeve. Background Art

[0002] A thermometer installation sleeve is a device specifically used for installing and protecting thermometers. It is made of high-quality materials such as stainless steel, copper, ceramics, etc., and has good corrosion resistance and wear resistance. These characteristics enable the sleeve to work stably for a long time in various harsh environments and provide reliable protection for thermometers. When replacing the thermocouple of a gas turbine turbine, for an integrated thermometer, due to working at a high temperature for a long time, the thread is particularly difficult to disassemble due to thermal expansion. Moreover, the installation position of the thermometer is relatively close to the wall, and due to the influence of the surrounding equipment, the operating space is extremely small. Each time the thermocouple is replaced, at least three people need to cooperate, and it takes 2 - 3 hours of effort to remove the old thermocouple, which is time-consuming and laborious. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a thermometer installation sleeve, which solves the problems raised in the background art.

Specific implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-6, A thermometer installation sleeve, comprising a junction box 1 and a main body tube 2. The main body tube 2 is installed at the bottom of the junction box 1. Inside the junction box 1, a thermocouple core 3 is installed, and the thermocouple core 3 is located inside the main body tube 2. The main body tube 2 is composed of an upper connecting tube 201 and a lower connecting tube 202. The left end of the installation box 101 is open and used for introducing and connecting wires. The upper connecting tube 201 and the lower connecting tube 202 can be disassembled. The bottom end of the upper connecting tube 201 is fixedly connected with a threaded plug B5, and the upper end of the lower connecting tube 202 is fixedly connected with a threaded plug A4. The threaded plug A4 and the threaded plug B5 are threadedly connected, which is beneficial for disassembling and assembling between the upper connecting tube 201 and the lower connecting tube 202. A through hole 6 is opened on the upper surface of the lower connecting tube 202, and the thermocouple core 3 is inserted into the through hole 6 and in contact with the through hole 6, which is beneficial for the thermocouple core 3 to be pulled out and also beneficial for improving the stability between the thermocouple core 3 and the through hole 6. A magnet A7 is fixedly connected to the inner bottom wall of the connecting shell 102. A magnet B8 is slidably connected to the outer surface of the thermocouple core 3. The magnet B8 is adsorbed to the magnet A7 and is in close contact with the thermocouple core 3, and there is a frictional force between the two. The frictional force between the magnet B8 and the thermocouple core 3 is less than the magnetic force between the magnet B8 and the magnet A7. The magnetic force between the magnet B8 and the magnet A7, combined with the magnetic force between the magnet B8 and the thermocouple, can improve the stability of the thermocouple core 3, prevent the thermocouple core 3 from falling off, and also enable the thermocouple core 3 to be disassembled. A detachable friction head 11 is installed at the bottom end of the lower connecting tube 202. An insertion socket 12 is opened on the upper surface of the friction head 11, and the thermocouple core 3 is inserted into the insertion socket 12 and in close contact with the insertion socket 12. A threaded sleeve 9 is fixedly sleeved at the bottom end of the lower connecting tube 202. A threaded groove 10 is provided on the outer surface of the friction head 11. The threaded sleeve 9 is threadedly connected to the threaded groove 10 and in close contact with the threaded groove 10, which is convenient for disassembling and assembling the friction head 11 and improving the sealing performance between the threaded sleeve 9 and the threaded groove 10. The junction box 1 is composed of an installation box 101, a connecting shell 102 and a top cover 103. The top cover 103 is used to protect the internal components and wiring. The installation box 101 is fixedly communicated with the main body tube 2. The connecting shell 102 is fixedly connected to the installation box 101. The connecting shell 102 is threadedly connected to the top cover 103. The outer surface of the thermocouple core 3 penetrates through the junction box 1 and is inserted into the junction box 1. The upper end of the thermocouple core 3 is in contact with the top cover 103.

[0023] In use, when the thermocouple core 3 needs to be replaced, only need to pull out the thermocouple core 3 upward. Since the bottom end of the thermocouple core 3 is inserted into the socket 12 inside the friction head 11, the bottom end of the thermocouple core 3 can be easily pulled out from the socket 12 and the through hole 6. The force required to pull out the thermocouple core 3 only needs to overcome the adsorption force of the magnet B8 on the thermocouple core 3 to pull out the thermocouple core 3 from the junction box 1, reducing the difficulty of replacing the thermocouple and improving work efficiency. Thus, when replacing later, it is not necessary to remove the thermometer sleeve, only the thermocouple core 3 needs to be removed. The work task that originally required 3 people to complete can now be easily completed by only 1 person, solving the problem raised in the background technology. When the friction head 11 needs to be replaced, since the threaded sleeve 9 and the friction head 11 are threadedly connected, only need to screw out the friction head 11 from the threaded sleeve 9 to take out the friction head 11, and the operation is simple and convenient.

[0024] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
