Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, and in particular to a portable transformer oil temperature controller. Background Technology

[0002] The transformer fiber optic winding temperature controller is a novel type of transformer winding temperature controller. Utilizing fiber optic temperature sensing technology, it reliably, quickly, and accurately measures the transformer oil surface temperature. Chinese utility model patent, authorization announcement number "CN221123614U," discloses a portable transformer oil surface temperature controller. This portable controller features a temperature sensor that penetrates deep into the transformer to detect its temperature. A transmission line connects to the temperature sensor to receive its signal. A signal demodulator connects to the transmission line to receive the signal and display the data. A receiving slot is provided on the side of the signal demodulator. A storage box is fitted into this slot, housing the temperature sensor and thus securing it to the side of the signal demodulator for easy carrying by operators.

[0003] During use, the above-mentioned technical solution has the drawback that the wiring harness is not designed for storage, which makes it easy for the temperature controller to scatter when carried. The excessively long wires cannot be properly stored and can only be haphazardly twisted or bundled. This not only results in a messy wiring layout that is prone to tangling and knotting, but also increases the burden of carrying the equipment. Furthermore, the messy wires are prone to getting caught on other equipment components, causing damage to the wiring or collisions with the equipment during transportation. Therefore, we propose a portable transformer oil temperature controller. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a portable transformer oil temperature controller. This solves the problem that, due to the lack of a storage structure for the connecting wires, the controller's wiring harness is easily scattered when carried, and the excessively long wires cannot be properly stored. They can only be haphazardly twisted or bundled. This not only leads to a messy wiring layout, which is prone to tangling and knotting, but also increases the burden of carrying the device. Furthermore, it is easy for the wires to get caught on other equipment components, causing damage to the wiring or damage to the device during transportation.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a portable transformer oil temperature controller, comprising:

[0027] Connecting wire 2, signal demodulator 1 and temperature sensor 3, one end of connecting wire 2 is fixedly connected to signal demodulator 1, and the end of connecting wire 2 away from signal demodulator 1 is fixedly connected to temperature sensor 3;

[0028] A wire harness storage structure is located on the signal demodulator 1.

[0029] The wire harness storage structure includes a mounting bracket 8, a mounting plate 4, two positioning rods 10, and a fixing plate 7. The mounting bracket 8 is fixedly connected to one side of the signal demodulator 1. The mounting bracket 8 has a "U" shaped structure. The mounting plate 4 is fixedly installed inside the mounting bracket 8 by bolts. The two positioning rods 10 are fixedly connected to the side of the mounting plate 4 away from the signal demodulator 1. The fixing plate 7 is fixedly connected to the end of the two positioning rods 10 away from the mounting plate 4. Both fixing plates 7 have through slots 9. Two fixing cylinders 5 are fixedly connected to the side of the two fixing plates 7 away from the mounting plate 4. Both fixing cylinders 5 are connected to the interior of the corresponding through slots 9. Two limiting grooves 11 are opened on the outer surface of both fixing cylinders 5. All four limiting grooves 11 have an "L" shaped structure.

[0030] The wire harness storage structure also includes two limiting blocks 13, two sliding plates 14, two rotating plates 15, and two springs 12. The two sliding plates 14 are slidably connected to the inside of the corresponding fixed cylinder 5. The two rotating plates 15 are rotatably connected to one side of the corresponding sliding plate 14. The two limiting blocks 13 are fixedly connected to the side of the corresponding sliding plate 14 away from the corresponding rotating plate 15. The two limiting blocks 13 are slidably connected to the inside of the corresponding through groove 9. Two limiting sliders 16 are fixedly connected to the outer surface of the two rotating plates 15. The four limiting sliders 16 are slidably connected to the inside of the corresponding limiting groove 11. The two springs 12 are fixedly connected to the side of the corresponding rotating plate 15 away from the corresponding sliding plate 14.

[0031] A card holder 6 is fixedly connected to the side of the fixed plate 7 away from the signal demodulator 1. The temperature sensor 3 is snapped into the inside of the card holder 6, and the inside of the card holder 6 has a "C" shaped structure.

[0032] Furthermore, when using the device, the temperature sensor 3 is responsible for monitoring the temperature of the transformer oil surface in real time and converting the temperature signal into an electrical signal. This electrical signal is transmitted to the signal demodulator 1 through the connecting wire 2. The signal demodulator 1 demodulates the electrical signal and converts it into identifiable and displayable temperature data, thereby achieving accurate monitoring of the transformer oil surface temperature. When it is necessary to store the connecting wire 2, the connecting wire 2 is wound around the outer surface of the two positioning rods 10.

[0033] When the connecting wire 2 is wound, it will squeeze the limiting blocks 13. The two limiting blocks 13 will drive the corresponding sliding plates 14 to slide inside the corresponding fixed cylinder 5, so that the two sliding plates 14 compress the corresponding springs 12 through the corresponding rotating plates 15, thereby facilitating the winding of the connecting wire 2 onto the outer surface of the two positioning rods 10. After the connecting wire 2 is wound onto the outer surface of the two positioning rods 10, the two limiting blocks 13 will reset under the elastic action of the corresponding springs 12, thereby facilitating the limiting of the wound connecting wire 2. When the two rotating plates 15 slide inside the fixed cylinder 5, they will drive the corresponding springs 12 to rotate. The two corresponding limiting sliders 16 slide inside the corresponding limiting grooves 11. After the connecting wire 2 is wound, the temperature sensor 3 is clipped into the inside of the bracket 6, which facilitates the limiting and fixing of the temperature sensor 3. When it is necessary to release the connecting wire 2, simply pull the two limiting sliders 16. The limiting sliders 16 will drive the limiting block 13 to be stored through the rotating plate 15 and the sliding plate 14. When the two limiting sliders 16 slide into the horizontal groove of the limiting groove 11, they will rotate, which facilitates the limiting of the rotating plate 15, and thus facilitates the release of the connecting wire 2.

[0034] The storage structure, consisting of positioning rod 10, limiting block 13, sliding plate 14, rotating plate 15 and spring 12, enables the orderly winding and fixing of the connecting wire 2. It eliminates the need for random bundling and allows excessively long wires to be tightly wound on positioning rod 10. The limiting block 13 automatically limits the wires, making the wire layout neat and completely preventing them from tangling and knotting. The wires will no longer fall apart when carried, greatly improving the convenience of carrying.
