Description

Technical Field

[0001] The utility model relates to the field of temperature measuring devices, in particular to a temperature measuring device for electric power fittings. Background Art

[0002] my country has a vast territory, and accordingly, the power grid covers a vast area, and it is also very difficult to ensure electricity supply. The more prominent problem is the contact resistance between power fittings and transmission and distribution lines. Contact resistance will occur when the transmission and distribution lines are connected to power fittings. If the contact is good, the contact resistance will be small, and the impact on the line will be small. If the connection is not firm or other reasons cause poor contact at the contact point, it will cause heat due to the large contact resistance, aggravate the oxidation of the contact surface, increase the contact resistance, and heat more violently. The temperature continues to rise, causing a vicious cycle, causing the metal at the connection point to change color or even melt.

[0003] Existing temperature detection is generally carried out by installing a temperature detection device on the power fittings, such as a temperature sensor to collect temperature data, and transmit the collected data to the host for analysis and processing. Based on the received data information, the temperature conditions of each transmission line are judged with the help of a background analysis program.

[0004] In fact, different electrical fittings have different models and sizes. Therefore, when installing the temperature sensor, it is necessary to select different installation locations and additional structures according to the corresponding shapes, which is difficult to unify, increasing the installation cost and difficulty. Utility Model Content

[0008] The utility model is further configured that a temperature sensor is installed on the top of one end of the clamping plate.

[0009] The utility model is further configured such that a mounting ring is fixedly arranged on one side of the top of the fixed shell, and a plurality of infrared temperature measuring heads are arranged on the inner wall of the mounting ring.

[0010] The utility model is further configured that an alarm light is installed at the bottom of the fixed shell, and a buzzer is installed at the bottom of the fixed box.

[0011] The utility model is further configured that the inner wall of the fixed clamping seat is provided with a rubber pad.

[0012] The utility model is further configured that a storage battery is installed inside the fixing box.

[0013] To sum up, the utility model mainly has the following beneficial effects: the utility model pulls out the movable plate from the fixed shell, and the splint is close to the electric fitting under the action of the torsion spring shaft, and the temperature measuring mechanism on the splint measures the temperature of the electric fitting; and when the splint is close to the electric fitting, the protrusion releases the squeezing of the blocking mechanism and makes it extend out of the movable plate, preventing the movable plate from sliding left and right during operation, causing the splint to detach from the electric fitting; the overall installation equipment is directly installed on the cable, and the splint is controlled by the elastic force of the torsion spring shaft, which can adapt to different types of electric fittings, effectively reducing the installation cost.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0020] A temperature measuring device for electric fittings, such as Figure 1-4 As shown, it includes a fixed base 1 and a fixed box 2, the fixed base 1, the inner wall of the fixed base 1 is provided with a rubber pad, the fixed base 1 and the rubber pad on the inner wall can be directly fixed to the cable, the fixing method of the fixed base 1 can be selected as a buckle, and the fixed base 1 is fixed by the buckle.

[0021] A fixed shell 3 is fixedly provided on one side of the fixed box 2, and a movable plate 4 is slidably provided on the inner wall of the fixed shell 3. A rotating column 8 is provided on one side of the movable plate 4. A clamping plate 11 is fixedly connected to the outer wall of the rotating column 8. The rotating column 8 and the movable plate 4 are connected by a torsion spring shaft 9, and a protrusion 10 is fixedly provided on the outer wall of the torsion spring shaft 9. A blocking mechanism is movably provided inside the movable plate 4. A plurality of spring columns 6 are installed at the bottom of the blocking mechanism, and the protrusion 10 is located above the blocking mechanism. The blocking mechanism includes a blocking plate 7 and a lifting plate 5.
