Description

Technical Field

[0001] The utility model belongs to the technical field of temperature detection equipment, and in particular relates to an online temperature detection device. Background Art

[0002] In the industrial and power industries, the normal operation of electrical equipment ensures the normal operation of society and the normal life of the people, so the reliability of equipment is crucial. Many companies advocate preventive maintenance of equipment, and temperature is the most important monitoring parameter in preventive maintenance. Too high or too low temperature means the possibility of failure. Realizing online temperature detection is an important means to ensure the safe operation of high-voltage equipment.

[0003] High temperature overheating directly leads to the decrease of mechanical strength and physical properties of electrical materials, and the increase of contact resistance. Continuous current flow will accelerate the oxidation of equipment connection points, which will cause the contact resistance to continue to increase, heat generation to intensify, and temperature to continue to rise, leading to high temperature overheating.

[0004] At present, temperature online detection devices are mostly used to detect temperature. However, in actual use, the temperature of fixed point areas is mostly detected, which limits the detection range of the detection device. When temperature detection is required for multiple points and multiple areas, multiple detection devices need to be installed for use, which is not only troublesome but also increases the overall cost of temperature detection. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an online temperature detection device, comprising a fixed cylinder, on which a turntable is rotatably connected; the turntable is rotatably connected to a crank, on which a connecting rod is rotatably connected; the turntable is rotatably connected to a rocker, and the other end of the rocker is rotatably connected to the connecting rod, and the crank, the connecting rod and the rocker constitute a crank-rocker mechanism; the rocker is coaxially fixed with a synchronization rod, on which a detector is fixed; the detector comprises a shell fixed to the rocker, and the shell is provided with a wireless temperature sensor.

[0007] Furthermore, a flange is fixedly connected to the fixing cylinder.

[0008] Furthermore, a motor coaxially fixed to the turntable is fixed to the flange.

[0009] Furthermore, a gear ring is fixedly connected to the fixed cylinder, and a planetary gear meshing with the gear ring is rotatably connected to the rotating disk.

[0010] Furthermore, the planetary gear is coaxially fixedly connected with a driving bevel gear, the driving bevel gear is meshed with a driven bevel gear, and the driven bevel gear is coaxially fixedly connected with the crank.

[0011] Furthermore, a stabilizing rod is fixedly connected to the rocker, and the other end of the stabilizing rod is fixedly connected to the synchronization rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the utility model is in use, through the crank-rocker mechanism composed of the turntable, the gear ring, the planetary gear, the active bevel gear, the driven bevel gear, the crank, the connecting rod and the rocker, the turntable can drive the synchronous rod and the detector thereon to swing back and forth along the turntable when the turntable rotates, so that the detector can detect the temperature within the detection range in all directions, thereby improving the detection range of the detector.
