[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] See also Figure 1-3 An embodiment of the present invention is as follows: an electric-driven fracturing equipment motor with a wiring protection mechanism comprises a motor body 1, a junction box 4 is fixedly installed at the front end of the motor body 1, a cooling box 7 is fixedly installed above the junction box 4, a temperature sensor 11 is fixedly installed above the inside of the junction box 4, and the temperature sensor 11 is a PT100 temperature sensor, a semiconductor refrigeration plate 9 is fixedly installed below the inside of the cooling box 7, a heat conduction plate 10 is fixedly installed inside the junction box 4 along the bottom of the semiconductor refrigeration plate 9, a cooling surface of the semiconductor refrigeration plate 9 faces the heat conduction plate 10, and the semiconductor refrigeration plate 9 is in close contact with the heat conduction plate 10.

[0018] When the motor is running for a long time, the temperature sensor 11 inside the junction box 4 can monitor the temperature inside the junction box in real time. When the temperature exceeds the safe range, the semiconductor refrigeration plate 9 can be started to transfer the cold temperature to the junction box through the heat conduction plate 10 to achieve cooling. This not only prevents the wiring part from aging faster due to excessive temperature, but also greatly reduces the risk of short circuit and fire, thereby ensuring the stable operation and safety performance of the motor under harsh working conditions.

[0020] The fan box 8 installed above the cooling box 7 and the heat dissipation fan 14 inside it, as well as the air intake filter plate 15 and the exhaust filter plate 13, form an effective heat dissipation channel, which not only improves the air circulation efficiency in the cooling box 7, but also can dissipate the heat of the heating surface of the semiconductor refrigeration plate 9, and prevents dust and other impurities from entering through the setting of the filter plate.

[0021] Furthermore, a square pipe 5 for incoming wires is fixedly installed below the junction box 4 , the junction box 4 is connected to the square pipe 5 , a sealing door 6 is rotatably installed at the front end of the junction box 4 , and an insulating layer 12 is fixedly installed inside the junction box 4 .

[0022] The inlet square tube 5 provided below the junction box 4 facilitates the introduction of the line into the junction box 4. The provision of the sealing door 6 facilitates the opening of the junction box 4 for wiring or maintenance of the line, thereby improving the practicality.

[0023] Furthermore, a mounting base 2 is fixedly installed below the motor body 1, and a cooling fan 3 is fixedly installed on one side above the motor body 1. The cooling fan 3 is connected to the inside of the shell of the motor body.

[0024] The cooling fan 3 fixed above the motor body 1 is connected to the inside of the motor housing, providing an additional heat dissipation path for the motor, which helps to reduce the temperature of the motor during operation and improve its working efficiency and service life.

[0025] Furthermore, a bottom groove is provided at the lower part of the mounting base 2, a layer plate 16 is fixedly installed inside the bottom groove of the mounting base 2, universal wheels 17 are symmetrically provided on both sides below the layer plate 16, a column 18 is fixedly installed above the universal wheel 17, and the upper end of the column 18 slides and extends to the top of the layer plate 16.

[0026] The bottom groove, layer plate 16, universal wheel 17 and column 18 and other components inside the mounting base 2 together form a motor support structure that is easy to move and adjust, so that the motor can be moved and positioned according to actual needs, thereby improving the deployment flexibility of the motor.

[0027] Furthermore, a U-shaped plate 19 is provided on the outer side of the upper end of the column 18, and the U-shaped plate 19 is fixedly connected to the layer plate 16. A hydraulic cylinder 20 is fixedly installed above the U-shaped plate 19, and an oil pump assembly of the hydraulic cylinder 20 is provided inside the bottom groove of the mounting base 2. The piston rod end of the hydraulic cylinder 20 slides and extends into the interior of the U-shaped plate 19 and is fixedly connected to the column 18.

[0028] The U-shaped plate 19, the hydraulic cylinder 20 and other components at the upper end of the column 18 allow the height of the column to be adjusted, so that the height of the universal wheel 17 can be raised or lowered as required, thereby increasing practicality.

[0029] Working principle: When in use, the internal temperature of the junction box 4 is monitored by the temperature sensor 11 during the long-term operation of the motor body 1. When the temperature exceeds the preset safety range, the semiconductor refrigeration plate 9 can be started, and the cooling surface of the semiconductor refrigeration plate 9 is in contact with the heat conduction plate 10 to transfer the cold temperature to the junction box 4, effectively cooling down to prevent the wiring part from aging due to high temperature, while reducing the risk of short circuit and fire. In addition, the fan box 8 above the cooling box 7 forms a heat dissipation channel through the heat dissipation fan 14, the air intake filter plate 15 and the exhaust filter plate 13, which enhances the air circulation in the cooling box 7, dissipates the heat on the heating surface of the semiconductor refrigeration plate 9, and prevents dust and other impurities from entering. By installing components such as the base frame 2, the layer plate 16, the universal wheel 17 and the column 18, a support structure that is easy to move and adjust is formed, which increases the flexibility of the motor.
