6. A method for remotely deploying a line detection device for relay protection in a substation according to any one of claims 1 to 5, characterized in that: The specific steps include: S1. After the storage assembly (100) is moved to the substation line detection point by the gripping rod and the pulley, the second electric telescopic rod (201) is started, and the extension end of the second electric telescopic rod (201) drives the reinforcement pad (202) to move downward until the reinforcement pad (202) is firmly in contact with the ground. The reinforcement pad (202) descends and drives the toothed plate (207) to descend. The toothed plate (207) descends and engages with the gear (206). The engagement of the gear (206) synchronously drives the rotating shaft (203) to rotate. The rotating shaft (203) drives the pulley (204) and the belt (205) to cooperate in transmission. The pulley (204) and the gear (206) cooperate in transmission to synchronously drive the rotating rod (106) to rotate. The rotating rod (106) drives the protective cover (107) to flip. When the reinforcement pad (202) contacts the ground, the corresponding protective cover (107) flips backward 180 degrees. S2. During the backward flipping process of the protective cover (107), the auxiliary pressure plate (307) is synchronously driven to rotate. When the auxiliary pressure plate (307) rotates 90 degrees, its inclined surface contacts the end of the vertical rod (306). As the auxiliary pressure plate (307) continues to flip backward, the auxiliary pressure plate (307) presses down the vertical rod (306). The vertical rod (306) descends and drives the U-shaped frame (303) to move downward. The U-shaped frame (303) drives the pressure rod (304) to move downward. The downward movement of the pressure rod (304) presses down the guide inclined plate (302). The guide inclined plate (302) is forced to drive the anti-sway card frame (301) forward. When the anti-sway card frame (301) moves forward, the top retaining edge of its inner cavity will separate from the multi-telescopic insulating sleeve rod (104) and break away from the limit enclosure. S3, the anti-sway card frame (301) moves forward and synchronously drives the trapezoidal inclined block (401) to move. When the trapezoidal inclined block (401) moves, its inclined surface will squeeze the surface of the multi-telescopic insulating sleeve rod (104), prompting the multi-telescopic insulating sleeve rod (104) to start turning upward from left to right with the rotating shaft (103) as the turning angle. As the trapezoidal inclined block (401) moves by squeezing, the arc-shaped groove (403) at the top of the trapezoidal inclined block (401) is finally forced to fit with the drag reduction sleeve (402). At this time, the raised end of the corresponding multi-telescopic insulating sleeve rod (104) is lifted to the top of the storage assembly (100); S4, the multi-telescopic insulating sleeve (104) flips and drives the rotating shaft (103) to rotate at the same time. After the multi-telescopic insulating sleeve (104) flips to the desired angle, the corresponding rotating shaft (103) stops rotating. At this time, the polygonal groove (108) opened on the surface of the front rotating shaft (103) is aligned with the polygonal plug shaft (112). Then, the first electric telescopic rod (109) is started. The first electric telescopic rod (109) starts its extended end to drive the L-shaped mounting plate (110) and the driving motor (111) to move backward. The driving motor (111) moves backward to drive the polygonal plug shaft (112) to fit with the polygonal groove (108). Then, the driving motor (111) is started to drive the polygonal plug shaft (112) and the rotating shaft (103) to finally adjust the electrical test angle of the multi-telescopic insulating sleeve (104). After the angle adjustment is completed, the multiple insulating sleeves inside the multi-telescopic insulating sleeve (104) are pulled out in sequence.

7. The method for remotely deploying a line detection device for relay protection in a substation according to claim 6, characterized in that: The rear side of the storage assembly (100) in S2 is provided with a limiting sliding groove that is slidably matched with the U-shaped frame (303).
