[0031] The present invention is described in more detail below with reference to the embodiments.

[0032] See also Figures 1 to 4 The portable substation primary lead terminal board reinstallation auxiliary device of this embodiment includes a variable speed motor 1, a wire drum 2, a wire rope 3, a limit block 4, a busbar terminal board 5, a primary lead terminal board 6 and a control module;

[0033] A handle 7 is provided on one side of the variable speed motor 1, a wire drum 2 is provided on the top of the variable speed motor 1, a central axis of the wire drum 2 is drivingly connected to an output shaft of the variable speed motor 1, one end of a wire rope 3 is fixedly connected to the wire drum 2, and the other end of the wire rope 3 is fixedly connected to a limit block 4, the wire rope 3 movably passes through a busbar terminal block 5 and a primary lead terminal block 6, the busbar terminal block 5 is close to one side of the variable speed motor 1, and the primary lead terminal block 6 is close to one side of the limit block 4, and the limit block 4 is used to limit and fix the primary lead terminal block 6;

[0034] The control module is electrically connected to the variable speed motor 1 .

[0035] In the present invention, the steel wire rope 3 is passed through the busbar terminal board 5 and the primary lead terminal board 6 in sequence. After passing through the primary busbar terminal board 5, the busbar terminal board 5 is limited by the limit block 4, the variable speed motor 1 is started, the steel wire rope 3 is collected on the wire drum 2, and at the same time, the primary lead terminal board 6 is driven close to the busbar terminal board 5 to complete the reinstallation.

[0036] In this embodiment, the variable speed motor 1 may adopt a brushless copper core motor to ensure stepless adjustment of the traction speed.

[0037] Furthermore, a battery module is installed at the bottom of the variable speed motor 1, and a battery 8 for providing electrical energy is detachably installed inside the battery module; the control module is electrically connected to a switch 9 for controlling the on and off power supply of the battery 8, and the switch 9 is set on the housing of the variable speed motor 1.

[0038] In this embodiment, the battery 8 is a removable lithium battery with a voltage of 20V and a capacity of not less than 4.0Ah to ensure the portability and flexibility of the device. The removable design of the battery 8 allows the battery 8 to be easily replaced or recharged after being exhausted, thereby ensuring the continuous operation capability of the variable speed motor 1.

[0039] At the same time, the switch 9 is arranged on the housing of the variable speed motor 1 for easy operation by the user. The switch 9 is used to control the start and stop of the variable speed motor 1. The user can easily turn on or off the motor, thereby controlling the running state of the motor.

[0040] Furthermore, a U-shaped groove is provided in the middle of the free end of the limit block 4, and a limit shaft 10 is hingedly provided in the U-shaped groove. By rotating the limit shaft 10, the primary lead terminal board 6 can be clamped to prevent the primary lead terminal board 6 from detaching.

[0041] Furthermore, it also includes a force sensor and a speed sensor. The force sensor is arranged on the wire rope 3, and the force sensor is used to detect the traction force of the wire rope 3; the speed sensor is arranged on the primary lead terminal board 6, and the speed sensor is used to detect the moving speed of the primary lead terminal board 6.

[0042] Furthermore, the force sensor and the speed sensor are both electrically connected to the control module, which receives the traction data collected by the force sensor and the movement speed data collected by the speed sensor, and adjusts the operating parameters of the variable speed motor 1 according to the traction data and the movement speed data.

[0043] In this embodiment, by using these two sensors in coordination, the traction force of the steel wire rope 3 and the moving speed of the primary lead terminal block 6 can be monitored in real time, thereby ensuring the operating efficiency and safety of the entire system.

[0044] The precise measurement of the force sensor can prevent the wire rope 3 from breaking due to overload, while the speed sensor helps to control the movement of the primary lead terminal block 6 to avoid equipment damage or operational errors caused by abnormal speed. This dual monitoring mechanism provides a strong guarantee for the stable operation of the equipment.

[0045] Furthermore, the control module adjusts the operating parameters of the variable speed motor 1 according to the traction force data and the moving speed data, including one adjustment, which specifically includes:

[0046] The control module compares the acquired moving speed data with the preset speed of the control module. If the moving speed data is less than or equal to the preset speed, the operating parameters of the variable speed motor 1 are not adjusted;

[0047] If the moving speed data is greater than the preset speed of the control module, the difference between the moving speed data and the preset speed of the control module is determined and the speed of the variable speed motor 1 is decelerated and adjusted.

[0048] Furthermore, after the first adjustment is completed, the control module performs a second adjustment on the operating parameters of the variable speed motor 1 according to the traction force data and the moving speed data. The second adjustment specifically includes:

[0049] The control module compares the acquired traction force data with the gravity of the primary lead terminal board 6 pre-stored in the control module. If the traction force data is equal to the gravity of the primary lead terminal board 6, no action is performed on the variable speed motor 1.

[0050] If the traction force data is greater than or less than the gravity of the primary lead terminal board 6, the force difference between the traction force data and the gravity of the primary lead terminal board 6 is determined, and the control module adjusts the operating parameters of the variable speed motor 1 according to the force difference and makes the traction force data equal to the gravity of the primary lead terminal board 6.

[0051] In this embodiment, by real-time monitoring of traction and moving speed, the control module can intelligently optimize the working state of the motor to ensure that the equipment operates at optimal efficiency and performance. When an increase in traction is detected, the control module can instruct the variable speed motor to reduce the speed to reduce energy consumption and avoid overload. This dynamic adjustment mechanism makes the entire system more flexible and efficient, while extending the service life of the equipment.

[0052] At the same time, the control module will accurately decelerate the speed of the variable speed motor 1 to ensure that the moving speed does not exceed the range required for safety or efficiency, thereby ensuring that the equipment can operate at optimal performance under various working conditions.

[0053] The control module can ensure that the traction force matches the gravity of the primary lead terminal block 6, thereby achieving precise movement control. If the traction force is equal to the gravity, it means that the current operating parameters have been able to meet the requirements and no further adjustment is required. On the contrary, if there is a force difference, the control module will make necessary adjustments to the operating parameters of the variable speed motor based on this difference to ensure that the traction force and gravity are balanced, thereby ensuring the smoothness and safety of the movement process.

[0054] Furthermore, it also includes an alignment module, which includes a plurality of photosensitive sensors, which are arranged in a ring shape around the mounting holes of the primary lead terminal board 6. The alignment module is electrically connected to the control module, and the control module receives the signal output by the alignment module and determines whether the busbar terminal board 5 and the primary lead terminal board 6 are aligned.

[0055] Furthermore, an alignment indicator light 11 is installed on the housing of the variable speed motor 1 , and the alignment indicator light 11 is electrically connected to the control module and is used to warn of the alignment status of the busbar terminal block 5 and the primary lead terminal block 6 .

[0056] Further, the alignment indicator light 11 emits green light when the busbar terminal block 5 and the primary lead terminal block 6 are aligned, and the alignment indicator light 11 emits red light when the busbar terminal block 5 and the primary lead terminal block 6 are not aligned.

[0057] Specifically, if the primary lead terminal block 6 is correctly aligned, the photosensor will detect the expected light pattern; if it is not aligned, the sensor will detect a different light pattern, thereby sending a signal to indicate that the position needs to be adjusted, ensuring the precise docking of the primary lead terminal block 6 and improving the installation efficiency and reliability of the entire device.

[0058] The control module is responsible for real-time monitoring and receiving the output signals from the photosensitive sensor; by analyzing these signals, the control module can determine whether the photosensitive sensor is completely blocked. If it is detected that the photosensitive sensor is not completely covered, it means that there is a misalignment between the busbar terminal block 5 and the primary lead terminal block 6. At this time, the control module will immediately send out a misalignment indication signal to remind the operator or the automatic system to make adjustments.

[0059] On the contrary, if all the photosensors are completely covered, the control module will confirm that the busbar terminal block 5 and the primary lead terminal block 6 have been correctly aligned, and send out an alignment indication signal, indicating that the next operation can be carried out.

[0060] If the mounting holes of the busbar terminal board 5 and the primary lead terminal board 6 are not aligned, the photosensors around the mounting holes of the primary lead terminal board 6 will receive light signals; if the mounting holes of the busbar terminal board 5 and the primary lead terminal board 6 are aligned, the photosensors around the mounting holes of the primary lead terminal board will be completely blocked and will not receive light signals, thereby determining whether the two are aligned.

[0061] The working principle of the present invention is as follows: the steel wire rope 3 is passed through the busbar terminal board 5 and the primary lead terminal board 6 in sequence. After passing through the primary busbar terminal board 5, the busbar terminal board 5 is limited by the limit block 4, the variable speed motor 1 is started, the steel wire rope 3 is collected on the steel wire drum 2, and at the same time, the primary lead terminal board 6 is driven close to the busbar terminal board 5 to complete the reinstallation.

[0062] The precise measurement of the force sensor can prevent the wire rope 3 from breaking due to overload, while the speed sensor helps to control the movement of the primary lead terminal block 6 to avoid equipment damage or operational errors caused by abnormal speed. This dual monitoring mechanism provides a strong guarantee for the stable operation of the equipment. By real-time monitoring of traction and moving speed, the control module can intelligently optimize the working state of the motor to ensure that the equipment operates at optimal efficiency and performance. When an increase in traction is detected, the control module can instruct the variable speed motor to reduce the speed to reduce energy consumption and avoid overload; this dynamic adjustment mechanism makes the entire system more flexible and efficient, while extending the service life of the equipment.

[0063] At the same time, the control module will accurately decelerate the speed of the variable speed motor 1 to ensure that the moving speed does not exceed the range required for safety or efficiency, thereby ensuring that the equipment can operate at optimal performance under various working conditions; the control module can ensure that the traction force matches the gravity of the primary lead terminal block 6, thereby achieving precise movement control. If the traction force is equal to the gravity, it means that the current operating parameters have been able to meet the requirements and no further adjustment is required. On the contrary, if there is a force difference, the control module will make necessary adjustments to the operating parameters of the variable speed motor based on this difference to ensure that the traction force and gravity are balanced, thereby ensuring the smoothness and safety of the moving process.

[0064] The alignment module and the control module are set up. The control module is responsible for real-time monitoring and receiving the output signals from the photosensitive sensor; by analyzing these signals, the control module can determine whether the photosensitive sensor is completely blocked. If it is detected that the photosensitive sensor is not completely covered, it means that there is a misalignment between the busbar terminal block 5 and the primary lead terminal block 6. At this time, the control module will immediately send out a misalignment indication signal to remind the operator or the automatic system to make adjustments.
