Description

Technical Field

[0002] A cable is a bundle of one or more insulated conductors, typically including an outer protective layer, used to transmit power or electrical signals. The design and construction of cables can vary depending on their intended use and installation environment. To monitor cable performance, temperature sensors are typically installed on the cable's outer wall.

[0003] For example, a cable temperature measuring device with publication number CN214407815U has a docking port in the middle of the bottom surface of the inner covering plate, and the probe is connected to the docking port; a middle groove is provided in the middle of the left and right sides of the top surface of the outer shell, and a vertical slide is provided in the middle of the left and right sides of the outer shell, the slide passes through the middle groove inward, and a slider is slidably connected inside the slide, and a supporting plate is fixed on the inner side of the slider, and the supporting plate is located in the middle groove and slidably connected thereto, and connection ports are provided at both front and rear ends of the top of the supporting plate, and a round tray or suction cup is connected to the top of each connection port by rotating a thread, and the slider is pushed back to let the sticker leave the wall, and the outer shell is continued to be moved to the temperature measurement position of the next cable for temperature measurement, without having to take off the outer shell multiple times, and the temperature measurement process is convenient and fast, which solves the problem that the temperature measurement process is relatively inconvenient, and a cable may need to be subjected to multiple temperature measurements, and the temperature measurement steps are relatively cumbersome;

[0004] The cable temperature measuring device detects the temperature of the cable through a temperature sensor, but the temperature sensor consumes electricity during use, so the battery needs to be replaced frequently during the cable temperature detection process, which is not very convenient to use. In order to solve the above problem, a cable temperature measuring device is proposed. Utility Model Content

[0007] A lower fixed plate, an iron core is fixedly installed inside the upper and lower fixed plates, a third support pad is fixedly installed on the upper end of the lower fixed plate, a temperature sensor is fixedly installed on the outer wall of the third support pad, the rectifier filter is electrically connected to the iron core, and the rectifier filter, DC / DC module and temperature sensor are all electrically connected through a guide.

[0008] Through the above technical solution, when it is necessary to measure the temperature of the cable, the upper fixing plate and the lower fixing plate are respectively fixed to the upper and lower sides of the cable. At this time, the iron core combination inside the upper fixing plate and the lower fixing plate, when current flows through the cable, there is an alternating magnetic field around the cable, and an induced voltage is generated through the iron core. The voltage is rectified and filtered by the rectifier filter and then enters the DC / DC module. The rectified voltage is stepped down by the DC / DC module and transmitted to the temperature sensor. The temperature of the cable is detected by the temperature sensor. This cable temperature measuring device does not require an external power supply to achieve measurement, does not affect the replacement of the battery, and provides convenience for cable temperature measurement.

[0009] In a preferred embodiment, the upper fixing plate and the lower fixing plate are respectively integrally provided with a first connecting column and a second connecting column on the left and right sides.

[0010] In a preferred embodiment, a locking pin is threadedly connected to the interior of the first connecting column, and a threaded hole is opened in the interior of the second connecting column.

[0011] With the above technical solution, after the upper fixing plate and the lower fixing plate are assembled, the locking pin is rotated to enter the threaded hole in the second connecting column, thereby fixing the upper fixing plate and the lower fixing plate.

[0012] In a preferred embodiment, a wireless communicator is fixedly mounted on one side of the third support pad, and the wireless communicator is connected to the temperature sensor signal.

[0013] Through the above technical solution, the temperature sensor detects data and uploads the data through the wireless communicator.

[0014] In a preferred embodiment, the upper fixing plate and the lower fixing plate are both semicircular structures.

[0015] In a preferred embodiment, the locking pin is made of insulating material.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention provides a cable temperature measuring device.
