It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Reference Figure 1 and 2 , the high-voltage grounding automatic connection device provided by the present invention is now described. The high-voltage grounding automatic connection device includes a bearing member 1, a detection mechanism 2 and a locking mechanism 3.

The main body 11 and the locking member 12 are integrally formed, and a grounding electrode locking hole 13 is provided at the connection between the main body 11 and the locking member 12. The grounding terminal is inserted into the grounding electrode locking hole 13, and the locking mechanism 3 shrinks the locking member 12, reduces the inner diameter of the grounding electrode locking hole 13, and then determines whether it is locked according to the data detected by the detection mechanism 2. The detection mechanism 2 is used to detect the pressure between the main body 11 and the locking member 12, and output a pressure signal and detect and output the real-time resistance information of the connection structure between the main body 11 and the locking member 12. After receiving the pressure signal, the locking mechanism 3 determines whether the locking mechanism 3 locks the grounding terminal according to the pressure signal. After receiving the real-time resistance information, the locking mechanism 3 determines whether the connection between the main body 11 and the locking member 12 is abnormal according to the real-time resistance information. The locking mechanism 3 adjusts the distance between the main body 11 and the locking member 12 and / or issues an alarm according to the judgment structure.

[0044] One end of the release member 35 is connected to the bracket 31, and the other end is connected to the second magnetic member 34.

A guide surface is provided on the side of the end of the sliding member near the lock head. A card slot is provided on the side of the lock head near the sliding member. In the process of the locking member 12 approaching the main member 11, the lock head is inserted into the lock hole, and the lock head pushes the sliding member into the slide groove through the guide surface. Finally, the sliding member is reinserted into the card slot under the action of the spring to lock the lock head.

The grounding terminal is inserted into the grounding electrode locking hole 13, and the locking mechanism 3 contracts the locking member 12, reduces the inner diameter of the grounding electrode locking hole 13, and then determines whether it is locked according to the data detected by the detection mechanism 2.

[0063] Compared with the prior art, the high-voltage grounding automatic connection device provided by the present invention is that when installing the grounding terminal, the grounding terminal is inserted into the grounding electrode locking hole 13, and the detection mechanism 2 detects the pressure between the main body 11 and the locking member 12, and determines whether the locking mechanism 3 locks the grounding terminal according to the pressure signal.

When the locking member 12 approaches the main body 11, it is a process of locking the grounding terminal, and vice versa, it is a process of loosening the grounding terminal.

[0068] Optionally, if the motor 321 receives a locking instruction, it drives the transmission shaft 322 to rotate to reduce the distance between the main body 11 and the locking member 12; if the motor 321 receives a stop instruction, it stops working.

[0073] Optionally, the anti-loosening locking high-voltage grounding device provided in this embodiment further includes a display 4 that is communicatively connected to the controller. The controller outputs a prompt signal according to the comparison result between the pressure signal and the pressure threshold, and the display 4 responds to the prompt signal.

[0074] Optionally, the controller outputs a prompt signal according to a comparison result between the pressure signal and the pressure threshold, including:

[0075] If the pressure signal is not lower than the locking threshold, the controller outputs an unlocking prompt instruction; if the pressure signal is lower than the locking threshold, the controller outputs a locking prompt instruction; if the pressure signal is higher than the loosening threshold, the controller outputs a loosening prompt instruction.

[0076] Optionally, the display 4 responds to the prompt signal, including:

[0077] After receiving the unlock prompt signal, the display 4 displays the word unlock and flashes a red light;

[0078] After receiving the locking prompt signal, the display 4 displays the word "locked" and emits a green light;

[0079] After receiving the loose signal, the display 4 displays the word "loose" and flashes a yellow light.

[0080] The control process of the anti-loosening locking high-voltage grounding connection device provided in this embodiment is as follows:

[0081] When the grounding terminal is inserted into the grounding electrode locking hole 13 and the grounding terminal triggers the auxiliary switch, the auxiliary switch controls the motor 321 to start working.

[0082] The motor 321 drives the transmission shaft 322 to rotate, and the transmission shaft 322 reduces the distance between the locking member 12 and the main member 11. As the locking member 12 gradually approaches the main member 11, the contact 22 begins to contact the pressure sensor 21. The pressure sensor 21 begins to detect the pressure between the main member 11 and the locking member 12. The pressure sensor 21 transmits the detected pressure data to the controller in real time in the form of a pressure signal.

[0083] The controller compares the received pressure signal with the pressure threshold, and outputs corresponding control instructions to the motor 321 according to the comparison structure.

[0084] If the pressure signal is not lower than the locking threshold, it means that the ground terminal has not been locked at this time, and the controller outputs a locking command to the motor 321. The motor 321 responds to the locking command and drives the transmission shaft 322 to rotate, thereby reducing the distance between the locking member 12 and the main body 11. At the same time, the controller outputs an unlocking prompt signal to the display 4. The display 4 responds to the unlocking prompt signal, displays the word unlocked, and flashes a red light.

[0085] If the pressure signal is lower than the locking threshold, it means that the ground terminal has been locked, and the controller outputs a stop command to the motor 321. The motor 321 responds to the stop command and stops working, the transmission shaft 322 stops rotating, and the locking member 12 is fixed at the current position. At the same time, the controller outputs a locking prompt signal to the display 4, and the display 4 responds to the locking prompt signal and prompts the word "locked".

[0086] After the device in this embodiment locks the ground terminal, the detection mechanism 2 detects the pressure data between the main body 11 and the locking member 12 in real time, and determines whether the ground terminal is loose.

[0087] If the pressure signal is lower than the loose threshold, it is determined that the ground terminal is loose. The controller outputs a locking command to the motor 321. The motor 321 responds to the locking command and drives the transmission shaft 322 to rotate, thereby reducing the distance between the locking member 12 and the main member 11. At the same time, the controller outputs a loose prompt command to the display 4, which responds to the loose prompt command, displays the word "loose", and flashes a yellow light.

[0088] During this process, the detection mechanism 2 continuously detects the pressure between the locking member 12 and the main member 11, and outputs a pressure signal to the controller. The controller determines whether to re-lock the ground terminal according to the pressure signal.

[0089] The detection mechanism also includes a resistance sensor for detecting the resistance at the connection between the main body 11 and the locking member 12. The resistance sensor is arranged at the connection between the main body 11 and the locking member 12, and the resistance sensor is connected to the controller for communication. The resistance sensor is used to detect and output the real-time resistance information at the connection between the main body 11 and the locking member 12 to the controller.

[0090] When the connection between the main body 11 and the locking member 12 is seriously corroded, the connection strength between the main body 11 and the locking member 12 will be reduced. At this time, the pressure between the main body 11 and the locking member 12 will not be abnormal, but the resistance of the connection will change significantly. Therefore, when the real-time resistance information exceeds the resistance threshold, the controller determines that the connection between the main body 11 and the locking member 12 is abnormal, and controls the display 4 to alarm and display the word "connection abnormality".

[0091] In a preferred embodiment, this embodiment provides a control method for an anti-loosening locking high-voltage grounding connection device. The method includes:

[0092] S1. Determine whether a ground terminal is inserted into the ground electrode lock hole 13.

[0093] S2. If the ground terminal is inserted into the ground electrode lock hole 13, proceed to step S3; otherwise, proceed to step S1 again.

[0094] S3. Lock the ground terminal.

[0095] The ground terminal locking operation is as follows: the motor 321 drives the transmission shaft 322 to rotate, thereby reducing the distance between the locking member 12 and the main member 11 and reducing the diameter of the ground electrode locking hole 13, thereby locking the ground terminal.

[0096] S4. Determine whether the ground terminal is locked. If locked, proceed to step S5; otherwise, proceed to step S3.

[0097] The determination of whether the ground terminal is locked is as follows: the detection mechanism 2 sends the detected pressure data to the controller, and the controller compares the pressure signal with the pressure threshold to determine whether the ground terminal is locked. If the pressure signal is not lower than the locking threshold, it means that the ground terminal has not been locked at this time, and the controller outputs a locking instruction to the motor 321. The motor 321 responds to the locking instruction and drives the transmission shaft 322 to rotate, thereby reducing the distance between the locking member 12 and the main body 11. At the same time, the controller outputs an unlocked prompt signal to the display 4. The display 4 responds to the unlocked prompt signal, displays the word unlocked, and flashes a red light.

[0098] If the pressure signal is lower than the locking threshold, it means that the ground terminal has been locked, and the controller outputs a stop command to the motor 321. The motor 321 responds to the stop command and stops working, the transmission shaft 322 stops rotating, and the locking member 12 is fixed at the current position. At the same time, the controller outputs a locking prompt signal to the display 4, and the display 4 responds to the locking prompt signal and prompts the word "locked".

[0099] S5. Determine whether the ground terminal is loose. If so, repeat step S3.

[0100] The detection mechanism 2 detects the pressure data between the main body 11 and the locking member 12 in real time, and determines whether the ground terminal is loose. If the pressure signal is lower than the loose threshold, it is determined that the ground terminal is loose. The controller outputs a locking command to the motor 321, and the motor 321 responds to the locking command and drives the transmission shaft 322 to rotate, thereby reducing the distance between the locking member 12 and the main body 11. At the same time, the controller outputs a loose prompt command to the display 4, which responds to the loose prompt command, displays the word loose, and flashes a yellow light.

[0101] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
