Description

Technical Field

[0001] The present invention relates to the field of distribution network equipment fault diagnosis, and in particular to a distribution network equipment fault diagnosis device and a use method thereof. Background Art

[0002] The existing power grid diagnostic device is a key component of the power system, mainly playing the role of real-time monitoring and fault warning. Therefore, the stable operation of the power grid diagnostic device is crucial. The existing power grid diagnostic device is usually composed of a main housing, a signal transmission device and a data acquisition device. The power grid diagnostic device generally needs to work around the clock and operate for a long time. However, long-term high-load operation will inevitably generate a lot of heat. To ensure that the power grid diagnostic device can continuously dissipate heat, the dustproof net on the power grid diagnostic device is crucial. The dustproof net can effectively block external dust and foreign matter from entering the device and protect key components such as the cooling fan from damage. At the same time, the dustproof net is also easy to accumulate dust. If it is not cleaned in time, it will seriously affect the heat dissipation effect and even cause equipment overheating failure.

[0003] For example, the utility model with application number CN201921316332.5 discloses a distribution network fault diagnosis device, which facilitates the disassembly and installation of the filter plate, is easy to use, and saves a lot of time. However, the distribution network equipment fault diagnosis device is installed under all-weather continuous operation, and manual participation is required in the disassembly and cleaning of the dustproof net, which affects the diagnostic device's barrier to external foreign matter when the cooling fan continues to dissipate heat, resulting in dust protection interruption.

[0004] Therefore, the existing structure and defects are studied and improved, and a distribution network equipment fault diagnosis device is proposed. Summary of the invention In view of the problems mentioned in the prior art, the present invention proposes a distribution network equipment fault diagnosis device and a method of use.

[0006] As a further improvement of the present invention, the first transition gear is also connected to a first guide shaft, and a support rod is provided at the end of the first guide shaft, wherein the top of the support rod is tightly fitted with the outer shell.

[0007] As a further improvement of the present invention, the top block is also connected to the end plate.

[0008] As a further improvement of the present invention, a collective shaft is provided in the middle of the first driving gear, and an auxiliary component for auxiliary heat dissipation is installed at the other end of the collective shaft.

A second guide shaft is rotatably provided at the bottom of the vertical rod. The second transition gear is also meshed with the second driving gear. A second cooling fan is also provided on the surface of the second driving gear.

[0010] As a further improvement of the present invention, a connecting disk is arranged outside the first driving gear, and inclined rods are installed on both sides of the surface of the connecting disk.

The rotation of the second driving gear can drive the second transition gear meshing with the second driving gear to rotate. Similarly, the rotation of the second transition gear can drive the second driving gear to rotate. The rotation of the second driving gear can drive the second cooling fan to rotate, which is beneficial to reduce the heat generated by the operation of the shell by reducing the driving parts to control multiple groups of heat dissipation structures, thereby reducing the introduction of external heat into the shell.

[0017] The rollers and brushes in the device are located on both sides of the dustproof mesh plate in a rotating state or move downward, and the ventilation area of ​​the dustproof mesh plate is cleaned by continuous rolling and friction. When the rollers and brushes are located on both sides of the dustproof mesh plate in a rotating state and continuously move downward, the brushes contact the combing teeth inside the bottom frame, and can assist in cleaning the cleaning debris carried by the brush by combing, making it easy to use the brush on the dustproof mesh plate again.
