Description

Technical Field

[0001] The utility model belongs to the field of temperature sensors, in particular to a temperature measuring sensor suitable for installation of electric wires and cables. Background Art

[0002] A temperature sensor is a device or apparatus used to measure temperature. It can convert temperature changes into electrical signals or other forms of output. When a cable transmits current, the electrical energy is converted into heat energy due to the resistance of the wire. When the current carried by the cable exceeds its rated capacity, the temperature of the cable rises faster. Excessive temperature may cause a fire risk.

[0003] In order to prevent the cable from causing a fire due to overheating, the cable temperature needs to be monitored in real time. Monitoring the cable temperature can help detect overload conditions early, thereby avoiding safety hazards caused by cable overheating. The temperature of the cable is usually monitored using a temperature sensor. After a certain number of years of use, the temperature sensor is affected by the aging of internal components and needs to be replaced. Continuous high temperature or frequent temperature changes may accelerate the aging and damage of the sensor. Therefore, the temperature sensor needs to be inspected and maintained regularly. The installation of temperature sensors is generally complicated. When disassembling them, not only do you need to use tools such as wrenches and screwdrivers, but it also takes a lot of time, which not only consumes a lot of manpower, but also affects the maintenance efficiency of the temperature sensor.

In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a temperature sensor suitable for installation of wires and cables, including a temperature sensor 1, a back plate 2 is fixedly connected to the back of the temperature sensor 1, a mounting groove 3 is provided on the back of the back plate 2, a fixing plate 4 is fixedly connected to the upper and lower ends of the back of the back plate 2, a rotating sleeve 5 is provided on the back of the fixing plate 4, a connecting block 6 is fixedly connected to the right side of the rotating sleeve 5 and the upper mounting groove 3, the two connecting blocks 6 are movably connected by a movable pin, and a fixing mechanism 7 is provided in the inner cavity of the rotating sleeve 5;

[0024] The fixing mechanism 7 includes a clamping plate 701, which is arranged in the inner cavity of the rotating sleeve 5. The inner cavity of the rotating sleeve 5 is threadedly connected with a threaded column 702. The front end of the threaded column 702 is movably connected to the back side of the clamping plate 701 through a bearing. Both sides of the back side of the clamping plate 701 are fixedly connected with limiting columns 703, and the rear end of the limiting column 703 passes through the rotating sleeve 5.

[0025] like Figure 1-4As shown, the model of the temperature sensor 1 is an optical fiber patch temperature sensor. Since the temperature sensor 1 will contact the surface of the cable when in use, it can detect the cable temperature in real time. The back plate 2, the installation groove 3, the fixing plate 4 and the rotating sleeve 5 cooperate to facilitate the installation of the temperature sensor 1 on the cable surface. Since the two connecting blocks 6 are movably connected by a movable pin, the angle of the rotating sleeve 5 can be adjusted to move the cable between the back plate 2 and the rotating sleeve 5. The fixing mechanism 7 is used to clamp and fix the cable located inside the rotating sleeve 5, thereby improving the stability of the temperature sensor 1 on the cable surface. At the same time, the temperature sensor 1 can be installed and removed by the fixing mechanism 7, which not only does not require the use of tools, but is also more convenient to operate. It can also reduce the manpower consumption during the installation and removal process, thereby improving the maintenance efficiency of the temperature sensor 1.

[0026] Example 2

[0027] Reference Figure 2 and 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0028] In this embodiment, rubber sleeves 704 are provided on both sides of the back plate 2 , and rotating rods 705 are movably connected to both sides of the back plate 2 through movable pins, and the rear ends of the rotating rods 705 are fixedly connected to the rubber sleeves 704 .

[0029] A receiving groove 8 is provided on the left side of the lower fixed plate 4 , and a movable column 9 is slidably connected to the inner cavity of the receiving groove 8 . The left end of the movable column 9 extends to the outside of the receiving groove 8 and is fixedly connected to a fixing plate 10 .

[0030] like Figure 2 and 4 As shown, by rotating the threaded column 702, the position of the clamping plate 701 can be adjusted so that it can move forward to clamp and fix the cable. During the movement of the clamping plate 701, the limiting column 703 can limit it to prevent its angle from deflecting. The rotating rod 705 is used to support the rubber sleeve 704. After the rubber sleeve 704 is sleeved on the surface of the cable, it can be further limited.

[0031] Example 3

[0032] Reference Figure 2 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, a positioning groove 11 is opened on the left side of the rotating sleeve 5, and a positioning column 12 is fixedly connected to the rear end of the rear side of the fixing plate 10. The rear end of the positioning column 12 extends to the inner cavity of the positioning groove 11 and engages with the inner cavity of the positioning groove 11.

[0034] A pull rod 13 is fixedly connected to the left side of the fixed plate 10 , and an anti-dropping block 14 is fixedly connected to the right end of the movable column 9 .

[0035] A spring 15 is fixedly connected to the right side of the anti-slip block 14 , and one end of the spring 15 away from the anti-slip block 14 is fixedly connected to the inner wall of the accommodating groove 8 .

[0036] like Figure 2 As shown, by pulling the pull rod 13, the fixing plate 10 can be driven to move, and the fixing plate 10 can drive the positioning column 12 to move, so that the positioning column 12 is moved out from the inside of the positioning groove 11. After being moved out, the angle of the rotating sleeve 5 can be adjusted so that the temperature sensor 1 can be moved out from the surface of the cable, so that the temperature sensor 1 can be repaired.

[0037] When the temperature sensor 1 needs to be installed during use, the temperature sensor 1 is first moved so that the cable is located between the installation groove 3 and the rotating sleeve 5. Then the threaded column 702 is rotated. The threaded column 702 can adjust the position of the clamping plate 701 during rotation so that it can move forward to clamp and fix the cable. During the movement of the clamping plate 701, the limiting column 703 can limit it to prevent its angle from deflecting. The rotating rod 705 is used to support the rubber sleeve 704, which is sleeved on the surface of the cable. After that, it can be further limited, and then the pull rod 13 is pulled forward. The pull rod 13 cooperates with the fixing plate 10 to drive the movable column 9 to move forward in the inner cavity of the accommodating groove 8. When moving, the movable column 9 will cooperate with the anti-slip block 14 to pull the spring 15 and cause the spring 15 to deform. Then, the pull rod 13 is rotated until the positioning column 12 is located directly in front of the positioning groove 11. At this time, the pull rod 13 is released. Under the action of the restoring elastic force of the spring 15, the positioning column 12 enters the inner cavity of the positioning groove 11 and engages with it, so that the rotating sleeve 5 can be positioned.
