Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor that is easy to install. Background Art

[0002] In order to accurately measure the temperature inside the pipeline, monitor and control the working status of the gas pipeline, the staff will install a temperature sensor outside the gas pipeline to detect the gas temperature inside the gas pipeline in real time. In order to install the temperature sensor on the pressurized pipeline, the staff will use a ball valve to prevent temperature leakage when installing the temperature sensor.

[0003] When the staff installs the temperature sensor on the pressurized pipeline, they first determine the installation position, and then weld a short tube at the position, with threads inside and outside the short tube, and then connect a ball valve to the outer thread of the short tube, and then use a drilling machine to drill through the short tube and the gas pipeline. When the drilling machine is taken out, the ball valve is closed to prevent gas leakage. Then the staff opens the ball valve and uses tools to install the thermometer sleeve, so that the thermometer sleeve is threadedly connected to the inner wall of the short tube. At this time, the thermometer sleeve will seal the short tube, and the staff then removes the ball valve and installs the thermometer in the thermometer sleeve to realize the installation of the temperature sensor. The use of the ball valve makes it convenient for the staff to install the temperature sensor on the pressurized pipeline and prevents gas leakage.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 5As shown, a temperature sensor that is easy to install includes a short tube 1, a sleeve 2 connected to the short tube 1 and a thermometer 3 connected to the sleeve 2. The outer wall of the short tube 1 is connected to a protective component, and the protective component includes two protective covers 4, two fixed blocks 6, a rotating shaft 7 and a connecting block 8. A placement groove 5 is opened in the protective cover 4, and the short tube 1, the sleeve 2 and one end of the thermometer 3 are all located in the placement groove 5. Two fixed blocks 6 are fixedly connected to the bottom of one protective cover 4, and a rotating shaft 7 is fixedly connected between the two fixed blocks 6. The bottom of the other protective cover 4 is fixedly connected to a connecting block 8, and the connecting block 8 is rotatably connected to the outer wall of the rotating shaft 7. An air pressure sensor 9 is fixedly connected to the inner wall of one protective cover 4, and a fixing component is connected to the top of the protective cover 4.

[0025] like Figure 1 As shown, a temperature sensor that is easy to install in the utility model is similar to the existing temperature sensor structure, such as a temperature sensor disclosed in the patent with publication number CN212585846U. The main improvement of the utility model is that the connection between the temperature sensor and the gas pipeline has a leak-proof structure, such as Figures 1 to 5 As shown, when a temperature sensor that is easy to install in the utility model is used, after installing the thermometer 3, the staff can move the protective component to move the placement groove 5 to the outside of the short tube 1 and the sleeve 2, and then the staff will close the two protective covers 4, and then use the fixing component to fix the two protective covers 4, and then electrically connect the air pressure sensor 9 with the external power supply and the network; when encountering a gas leak, the leaked gas will enter the placement groove 5, so that the air pressure in the placement groove 5 increases, and the air pressure sensor 9 will send a signal after detecting the increase in air pressure, and transmit the leakage data and the leakage position to the terminal device in the hands of the staff through the network, and send an alarm to the staff, so that it is convenient for the staff to quickly take measures to the leakage position to prevent dangerous accidents.

[0026] By arranging a protective cover 4 outside the short tube 1 and arranging an air pressure sensor 9 inside the protective cover 4, and utilizing the cooperation between the protective cover 4 and the air pressure sensor 9, an early warning can be issued to the staff when a gas leak occurs, so that the staff can quickly find the gas leak location, deal with the gas leak accident, and prevent major accidents; at the same time, the placement groove 5 can also provide a buffer for the leaked gas, preventing the leaked gas from directly escaping into the air, further increasing the safety of the staff and equipment.

[0027] like Figure 2 and Figure 5 As shown, the fixing assembly includes a fixing plate 10, a bolt 11 and a nut 12. The tops of the two protective covers 4 are fixedly connected with symmetrically arranged fixing plates 10. The bolt 11 passes through the two fixing plates 10 at one end and is threadedly connected with the nut 12. A connecting groove 13 corresponding to the position of the nut 12 is opened on the surface of the fixing plate 10.

[0028] Specifically, by utilizing the cooperation between the nut 12 and the bolt 11, the two fixing plates 10 are clamped, and then the protective cover 4 is clamped, thereby increasing the sealing of the protective cover 4 and preventing gas leakage from the protective cover 4. At the same time, it also brings convenience to the staff in installing and removing the protective cover 4.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a sealing sleeve 14 is fixedly connected to the outer wall of the protective cover 4 , and the two sealing sleeves 14 fit together, and the sealing sleeve 14 fits together with the outer wall of the short tube 1 and the outer wall of one end of the thermometer 3 .

[0030] Specifically, the sealing sleeve 14 can further improve the sealing performance of the placement groove 5 , prevent the gas from leaking from the placement groove 5 , and improve the practicality and protection capability of the protective cover 4 .

[0031] like Figures 2 to 5 As shown, a reinforcing frame 15 is fixedly connected to the inner wall of the protection cover 4 .

[0032] Specifically, the reinforcing frame 15 can strengthen the strength of the protective cover 4 , improve the impact resistance of the protective cover 4 , prevent the protective cover 4 from deforming and causing sealing failure, and increase the stability of the protective cover 4 .

[0033] like Figure 5 As shown, a hexagonal groove 16 matching the position and shape of the head of the bolt 11 is formed on the surface of the fixing plate 10 .

[0034] Specifically, the hexagonal groove 16 can be used to fix the bolt 11 , which provides convenience for the staff to connect the bolt 11 with the nut 12 .

[0035] like Figure 3 and Figure 5 As shown, a rotating plate 17 is fixedly connected to the surface of the nut 12 .

[0036] Specifically, the rotating plate 17 can provide a hand fulcrum for the worker to rotate the nut 12, provide convenience for the worker to rotate the nut 12, and increase the comfort of the worker's hand.

[0037] like Figure 3 and Figure 5 As shown, the cross section of the rotating plate 17 is dovetail-shaped.

[0038] Specifically, the dovetail-shaped rotating plate 17 has a larger contact area with the staff's hands, making it easier for the staff to turn the nut 12; at the same time, the corners of the rotating plate 17 are chamfered to prevent the staff's skin from being scratched by the rotating plate 17 when the hand slips.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
