High -voltage plug -in rod connects high -voltage output unit, and output voltage is usually as high as 30KV or more.

[0004] The following safety risks exist in the use process of high -voltage plug -in rod at present:

[0005] First, when the connection state of high -voltage plug -in rod is not effectively detected, high voltage is directly output, and once the plug -in rod is not in the correct position, serious safety accidents such as electric shock injury of personnel are easily caused. Secondly, when operating personnel carry out cable reel winding and unwinding operation, they often operate due to operation habit in the case that high -voltage plug -in rod has not been completely pulled out and separated from cable reel high -voltage socket, at this time, cable reel rotation will drive high -voltage plug -in rod line to rotate, causing high -voltage plug -in rod connecting line to twist and break, which not only damages equipment, but also may cause safety accidents due to line damage. Finally, in the high -voltage output operation process, if relevant motor rotation is caused due to misoperation, the cable reel far end high -voltage output line will also fall off, which will bring great safety hazard.

[0006] Based on the above reasons, the utility model designs a kind of high -voltage plug -in rod insertion and in -place detection device, which is combined by specific mechanical structure and sensing element, realizes the accurate detection of high -voltage plug -in rod insertion high -voltage socket state,

[0007] As long as high -voltage plug -in rod is inserted into cable reel high -voltage socket, motor rotation is strictly prohibited, and only when plug -in rod is completely inserted in place can voltage operation be carried out, which can effectively avoid safety accidents caused by plug -in rod not in place or misoperation, and ensure the safe operation of equipment and personnel safety. SUMMARY

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] See Figs. 1-3 This utility model provides a high-voltage plug insertion and positioning detection device, including a cable reel base. A mounting frame 6 is provided on one side of the cable reel base. A high-voltage socket 1 for the cable reel is provided in the mounting hole above the mounting frame 6 and connected to the cable reel. A locking nut 3 is provided on the high-voltage plug tube 2 of the high-voltage plug corresponding to the high-voltage socket 1. A positioning induction switch 4 is provided on the outside of the mounting frame 6 and below the high-voltage socket 1. An insertion induction switch 5 is provided on the outside of the positioning induction switch 4. A control box 7 is provided between the mounting brackets on the other side of the cable reel base. The control box 7 is electrically connected to the high-voltage socket 1, the positioning induction switch 4, and the insertion induction switch 5.

[0026] A motor electrically connected to control box 7 is located on the other side of the cable reel.

[0027] When the locking nut 3 is locked to the high-voltage socket 1 of the cable reel, a position sensing switch 4 triggered by compression is provided below the locking nut 3.

[0028] The high-voltage plug tube 2 is connected to the outer high-voltage conductor.

[0029] The mounting holes of mounting frame 6 are on the same horizontal line as the motor shaft on the other side of the cable reel.

[0030] Insert induction switch 5, which is a photoelectric switch.

[0031] The working principle of this utility model is as follows:

[0032] like Fig. 1 As shown, the high-voltage socket 1 of the cable reel is securely installed in the designated position on the mounting frame 6 according to the design requirements, ensuring that the installation angle and position accuracy of the socket meet the standards, so as to ensure that the high-voltage plug tube 2 can be smoothly inserted.

[0033] Install the positioning induction switch 4 and the insertion induction switch 5 at appropriate positions on the outer side of the mounting frame 6 and below the high-voltage socket 1 of the cable reel. During installation, the positions and angles of the two switches need to be precisely and repeatedly adjusted so that the positioning induction switch 4 can be reliably triggered when the high-voltage plug locking nut 3 is properly pressed, and the insertion induction switch 5 can accurately sense whether the high-voltage plug tube 2 is inserted into the high-voltage socket 1 of the cable reel.

[0034] Assemble the high-voltage plug tube 2 with the locking nut 3, and then install the assembled component with the high-voltage socket 1 on the cable reel. During installation, ensure that the high-voltage plug tube 2 is inserted smoothly and that the locking nut 3 can effectively fix the high-voltage plug tube 2, ensuring a tight and stable connection.

[0035] Connect each functional circuit to control box 7 and verify to ensure the effectiveness of the entire circuit. After completing the installation of all components, conduct a comprehensive inspection of the entire device. Check whether the installation of each component is secure, the connection is correct, and the operation of the inductive switches is normal. Perform simulation tests to verify whether the functions of the high-voltage plug positioning inductive switch 4 and the high-voltage plug insertion inductive switch 5 meet the design requirements, ensuring that the device can operate normally.

[0036] When operation is required, the operator first slowly inserts the high-voltage plug tube 2 into the high-voltage socket 1 of the cable reel and tightens the locking nut 3 (e.g., Fig. 2 As shown in the diagram, once the position is reached, the control box 7 will automatically make a judgment and allow subsequent pressurization operations. If the position is not reached, the control box 7 will prevent pressurization.

[0037] At this point, if the operator can perform the subsequent pressure boosting operation according to the work procedure, it indicates that the high-voltage plug is inserted in place; if the pressure cannot be boosted, it indicates that the position sensing switch 4 has not been triggered. It is necessary to check whether the high-voltage plug tube 2 is inserted in place, whether the locking nut is tightened, etc., and make adjustments until the position sensing switch 4 of the high-voltage plug tube 2 is working normally.

[0038] Throughout the operation, as soon as the high-voltage plug 2 is inserted into the high-voltage socket 1, the insertion induction switch 5 will immediately send a signal to stop the cable reel rotary motor and keep it locked. Only after the high-voltage plug 2 is completely removed from the high-voltage socket 1 will the control box 7 release the lock on the cable reel rotary motor and proceed with subsequent cable winding and unwinding operations.

[0039] In addition to installation and operation, the maintenance and upkeep steps of this utility model are as follows:

[0040] Regularly inspect and test the position sensing switch 4 and insertion sensing switch 5. By simulating the insertion and positioning of the high-voltage plug tube 2, test the switching sensitivity and signal transmission reliability to ensure normal operation in actual use. If any switch malfunction or performance degradation is found, repair or replace it promptly.

[0041] Regularly inspect the wear of the high-voltage plug tube 2, locking nut 3, and high-voltage socket 1 of the cable reel. If severe wear is found on the parts, affecting the stability and reliability of the connection, replace them in time to ensure the normal operation of the device.

[0042] Regularly inspect the structural integrity of the mounting frame 6, checking for any loosening, deformation, or other problems. If any issues are found, repair or reinforce them promptly to ensure that the mounting frame 6 provides a stable foundation for all components and guarantees the normal operation of the device.

[0043] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0045] This invention comprehensively addresses numerous safety risks inherent in the use of high-voltage plugs in existing technologies. By incorporating two inductive switches, it rigorously detects, determines, and proactively controls the insertion of the high-voltage plug into the high-voltage socket of the cable reel, preventing safety accidents caused by plug connection problems and misoperation, thus ensuring the safety of workers. In practical applications, multiple tests have demonstrated that this invention accurately detects the plug's positioning, with an error controlled within ±1mm. Compared to traditional methods, this system offers higher precision and stability and is unaffected by ambient light and mechanical wear.
