Description

Technical Field

[0001] The invention belongs to the technical field of transformer equipment cleaning tools, and in particular relates to a casing thread grinding and rust removal tool. Background Art

[0002] In outdoor environments, transformer bushing terminals are exposed to the sun and rain for a long time, and rust often occurs. The existing treatment method requires the use of sandpaper to carefully polish the threaded parts manually to remove the oxide layer. This work is extremely challenging. If the threads are damaged, it will not only hinder the subsequent installation work, but also cause poor contact, which is unacceptable for the safety and stability of the power system. The staff needs to have a high degree of patience and fine operating skills. On the one hand, they must resolutely remove the rust under the coating, and on the other hand, they must protect the threads from damage. Grinding work is usually time-consuming and labor-intensive, especially in bad weather or complex working environments. In addition, in the actual cleaning process, it is also common to use brushes and rags for cleaning. This cleaning method is not only inconvenient to operate, but also not clean thoroughly, and has no obvious cleaning effect on the oxide layer. Summary of the invention

[0005] The present invention further illustrates that the housing is also provided with a charging socket, which is connected to the power module. The charging socket is a device power charging port and a circular interface.

[0006] The present invention further describes that the rust removal and grinding brush strip is rectangular and is provided with a clamping position for clamping the soft steel wire to ensure the rust removal effect.

[0007] The present invention further states that the chamfering installer is a circular sleeve made of aluminum alloy, and is provided with three square holes on the outer surface for installing the rust removal and grinding brush strip. The chamfering installer uses screws to install the brush head (brush strip), and the bristles can be installed according to different work requirements. When in use, the sleeve is inserted into the terminal, and then rotating and grinding is performed.

[0008] The present invention further describes that the adapter is a cylindrical joint made of aluminum alloy, and is fastened together with the reduction output shaft by transverse screws to ensure that no displacement occurs during rotational grinding, thereby ensuring safety performance.

[0009] The present invention further illustrates that the deceleration module adopts a reducer. The deceleration module can reduce the motor speed and transmit the rotational power on the motor to the cleaning head to meet the rust removal requirements, while increasing the torque to extend the service life of the motor.

[0010] The present invention further illustrates that the power module uses a lithium battery to provide electrical energy for the normal operation of the tool, and has the characteristics of small size and large capacity.

[0011] The present invention further describes that the motor module is a power structure (motor) that converts electrical energy into power and completes the functional requirements of removing rust and oxide layers of the terminal through its forward and reverse rotation.

[0012] The present invention further illustrates that the switch control module is a switch control circuit board, which controls the working state of the motor module by operating the reversing switch and the starting switch. The reversing switch is a gear switch that can adjust the forward and reverse rotation of the motor; the starting switch is the on and off of the power supply of the entire device.

[0014] Advantages of the present invention: The structural design of the present invention is scientific and reasonable, and the production and use costs are low. Before cleaning, the flexible steel wire is clamped on the rust removal and grinding brush bar, and the rust and oxide film on the surface of the terminal are removed by the flexible steel wire. The wire brush rust removal usually utilizes an electric motor to drive a device fixed with a wire brush to perform high-speed grinding on the rusted workpiece surface, thereby removing the rust layer, debris and loosely attached oxides on the workpiece surface, so that the workpiece surface obtains good cleanliness; the overall tool is easy to operate, the service life of the terminal is extended, and the economic benefits are improved.
