Technical Field

[0001] The invention belongs to the technical field of electric power device inspection equipment, and in particular relates to an automatic inspection equipment for a relay protection device. Background Art

[0002] Relay protection technology is one of the key technologies in the power system. Its main function is to monitor and judge the operating status of power equipment by measuring various parameters in the power system (such as current, voltage, frequency, etc.) when a power system fault occurs, and take timely measures to prevent equipment damage or system accidents. The basic principle of the relay protection device is to judge the operating status of the equipment based on the changes in electrical quantities. Once an abnormality is found, the fault circuit is quickly cut off to protect the stable operation of the entire power system.

[0003] Relay protection device inspection is one of the important tasks of substation operation and maintenance personnel. Through regular inspection of relay protection devices, inspection operators can grasp the operating status of the equipment in advance and avoid serious equipment operation failures. With the promotion of unmanned substations and the rapid growth of relay protection devices in substations, the difficulties of traditional protection inspections and regular inspections are gradually emerging. The operating data of relay protection devices still relies on periodic inspections by operation and maintenance personnel. At present, the operation and maintenance of power transmission and transformation enterprises have problems such as large inspection workload, low efficiency, and inaccurate observation.

[0026] The lifting rod 8 is hinged to the shift rod 6 , and the telescopic rod 10 is hinged to the shift rod 6 and the connecting shaft 9 .

[0027] When the present invention is in use, the control mechanism 11 controls the operation of the entire device. The design of the wheat wheel 2 enables the vehicle body to move flexibly in a complex environment, adapt to different terrains and obstacles, and effectively complete the patrol work. The vehicle body 1 is controlled to move by the control mechanism 11, and patrols are carried out according to the preset route. The height and angle of the lifting bracket 3 are adjusted as needed, so that the patrol box 4 can accurately align with the relay protection device. When the lifting bracket 3 is in use, the telescopic rod 10 is extended to drive the connecting shaft 9 to move, and the lifting rod 8 can be adjusted to cross and rise. The shift rod 6 moves inside the slide 5 through the slider 7 to ensure the stability of the lifting bracket 3. The relay protection device is monitored and recorded by the patrol instrument 27, and the monitored data is transmitted to the control mechanism in real time, and then transmitted to the background system. The staff can view and analyze the data through the background system, and timely discover and handle abnormal situations. This device can correctly and efficiently complete the task, and improve the safety and stability of the relay protection device and the power system. Example

[0028] like Figure 1-4 As shown, an automatic patrol device for a relay protection device comprises a vehicle body 1, a control mechanism 11 is arranged at the lower side of the vehicle body 1, a wheat wheel 2 is arranged at the bottom of the vehicle body 1, a slide groove 5 is arranged on the surface of the vehicle body 1, a lifting bracket 3 is arranged on the upper side of the vehicle body 1, the lifting bracket 3 comprises a shift rod 6, the end of the shift rod 6 cooperates with the slide groove 5 through a slider 7, a lifting rod 8 is hingedly arranged between the shift rods 6, a connecting shaft 9 is arranged between the lifting rods 8, a telescopic rod 8 is arranged between the connecting shaft 9 and the shift rod 6, and a patrol box 4 is arranged above the lifting bracket 3.

[0029] For better effect, the lifting rod 8 is hinged to the shift rod 6 , and the telescopic rod 10 is hinged to the shift rod 6 and the connecting shaft 9 .

[0030] For better effect, an anti-collision device 12 is provided at the corner of the vehicle body 1, and the anti-collision device 12 includes a chuck 14, and the chuck 14 is connected to the vehicle body 1 through a column 13. A base 15 is provided at the bottom of the chuck 14, and a tray 16 is provided on the upper side of the base 15. A positioning hole 17 is provided in the middle of the tray 16, and a cover plate 19 is provided on the upper side of the chuck 14. A through hole 20 is provided in the middle of the cover plate 19, and an anti-collision ring 18 is provided between the cover plate 19 and the tray 16. A positioning bolt 21 is provided inside the cover plate 19, and the positioning bolt 21 passes through the through hole 20 and is screwed to the positioning hole 17.

[0031] For better effect, the column 13 is vertically placed on the upper side of the vehicle body 1, and a bearing is arranged between the column 13 and the vehicle body 1. The bearing facilitates the rotation of the bumper 12 and the column 13 when impacted, and can transfer and alleviate the impact force.

[0032] For better effect, the anti-collision ring 18 is circular in shape and made of butadiene rubber. Butadiene rubber has good elasticity and wear resistance, can further absorb the impact force during collision, and protect the safety of the equipment.

[0033] For better effect, the diameter of the anti-collision ring 18 is between the diameter of the tray 16 and the diameter of the cover plate 19. The anti-collision ring 18 can be stably placed between the base 15 and the cover plate 19 to prevent the anti-collision ring 18 from falling off.

[0034] When the present invention is in use, the control mechanism 11 controls the operation of the entire device. The design of the wheat wheel 2 enables the vehicle body to move flexibly in a complex environment, adapt to different terrains and obstacles, and effectively complete the inspection work. The vehicle body 1 is controlled to move by the control mechanism 11, and the inspection is carried out according to the preset route. The height and angle of the lifting bracket 3 are adjusted as needed, so that the inspection box 4 can accurately align with the relay protection device. When the lifting bracket 3 is in use, the telescopic rod 10 is extended to drive the connecting shaft 9 to move, and the lifting rod 8 can be adjusted to cross and rise. The shift rod 6 moves inside the slide groove 5 through the slider 7 to ensure the stability of the lifting bracket 3. Further, an anti-collision device 12 is provided at the corner of the vehicle body 1. When the anti-collision device 12 is in use, the anti-collision ring 18 is placed on the upper side of the pallet 16 to ensure that the anti-collision ring 18 can completely cover the central area of ​​the pallet, and the cover plate 19 is placed above the anti-collision ring 18. The positioning bolt 21 is passed through the through hole 20 of the cover plate 19, and then screwed into the positioning hole 17 of the pallet 16 to fix the cover plate 19 and the anti-collision ring 18. When the vehicle body 1 may encounter obstacles or collision risks during movement, the anti-collision device 12 will automatically function. If the vehicle body 1 collides, the anti-collision ring 18 will first contact the obstacle and absorb part of the impact force. The design of the anti-collision ring 18 and the bearing will allow the anti-collision device 12 to deform and rotate to a certain extent when subjected to impact force, thereby further reducing the damage to the vehicle body 1 caused by the collision. The relay protection device is monitored and recorded by the patrol instrument 27, and the monitored data is transmitted to the control mechanism in real time, and then transmitted to the background system. The staff can view and analyze the data through the background system, and promptly discover and handle abnormal situations.
