[0002] Before the battery verification discharge test of the DC system of the substation or the replacement of the battery pack, in order to ensure the safe and stable operation of the DC system, a temporary battery pack needs to be assembled and connected to the DC system before the original battery pack can be withdrawn to work on it. After the temporary battery pack is assembled indoors, insulation measures need to be taken for the temporary battery pack to prevent short circuit.

[0031] A fixed platform 4 is provided at one end of the support of the insulating base mechanism 1, and a telescopic cover 3 is provided on one side of the frame of the fixed platform 4 along the telescopic direction of the insulating base mechanism 1. The telescopic cover 3 is an accordion cover structure. By utilizing the extension of the telescopic cover 3 in the form of an accordion cover, the telescopic cover 3 is pulled to extend, and the cover is placed above the modularly placed spare battery pack to provide an insulating cover and rain protection.

[0032] A telescopic frame mechanism 2 is arranged inside the cover of the telescopic hood 3, and the telescopic frame mechanism 2 includes two horizontally opposite groups of support frames 21, and a first telescopic gallows 22 is symmetrically connected between the two opposite groups of support frames 21 along the vertical direction, and a second telescopic gallows 23 is symmetrically connected between the two opposite groups of support frames 21 along the transverse direction. When the telescopic hood 3 is extended, the combination of the first telescopic gallows 22 and the second telescopic gallows 23 is driven to fold and extend, and the synchronous extension of the overall structure of the telescopic frame mechanism 2 is utilized to support and protect the telescopic hood 3, avoid deformation of the telescopic hood 3 caused by external impact, and improve the cover protection safety of the telescopic hood 3.

[0033] The vertical frame of the support frame 21 is provided with a first guide slot 24, the top of the telescopic frame of the first telescopic gallows 22 is provided with a first guide slide buckle 25 guided by the first guide slot 24, the transverse frame of the support frame 21 is provided with a second guide slot 26, the top of the telescopic frame of the second telescopic gallows 23 is provided with a second guide slide buckle 27 guided by the second guide slot 26, during the telescopic and unfolding process of the telescopic frame mechanism 2, when the first telescopic gallows 22 is extended, the first telescopic gallows 22 is stably telescoped and unfolded by utilizing the buckle combination of the first guide slot 24 and the first guide slide buckle 25, and then when the second telescopic gallows 23 is extended, the second telescopic gallows 23 is stably telescoped and unfolded by utilizing the buckle combination of the second guide slot 26 and the second guide slide buckle 27.

The top of the cover plate of the flap 5 is provided with a plurality of combination pages 8 connected to the telescopic cover 3, and the inner plate of the flap 5 is symmetrically provided with a clamping buckle 6 opposite to the telescopic frame mechanism 2. After the telescopic cover 3 is used to cover the spare battery pack, the flap 5 can be closed to form a left-right symmetric form with the fixing platform 4, and the openings on both sides of the telescopic cover 3 are sealed, and then the spare battery pack is fully covered. When the flap 5 is flipped and closed, the clamping buckle 6 is flipped and stuck into the two sides of the first guide slide buckle 25 of the telescopic frame mechanism 2, so that the first guide slide buckle 25 is restricted from sliding in the first guide slide groove 24, and then the first telescopic gallows 22 is restricted from telescoping, which plays a limiting and fixing function, so that the telescopic frame mechanism 2 after extension is extended and fixed, and the extension stability of the telescopic cover 3 is improved.

[0035] The bottom end of the cover plate of the flip cover 5 is provided with a locking mechanism 7 which is locked with the insulating base mechanism 1. The locking mechanism 7 includes a track frame 71. The guide rail of the track frame 71 is rotatably connected with a transmission shaft 75. The middle of the guide rail of the track frame 71 is provided with an opening and closing knob 72 which is opposite to the transmission shaft 75. The central axis of the opening and closing knob 72 is installed with a bevel gear A73. The middle of the shaft of the transmission shaft 75 is provided with a bevel gear B74 which meshes with the bevel gear A73. The two sides of the shaft of the transmission shaft 75 are symmetrically provided with transmission screws 77.

A transmission slide 76 guided by the track frame 71 is sleeved on each of them, and the threads of the two opposite sets of transmission screw rods 77 are arranged symmetrically in forward and reverse directions. By turning the opening and closing knob 72, the bevel gear A73 is driven to rotate, and the meshing transmission of the bevel gear A73 and the bevel gear B74 is used to drive the transmission shaft 75 to rotate, and then the two opposite sets of transmission screw rods 77 on the shaft are driven to rotate, and the threads arranged in forward and reverse directions on the two sets of transmission screw rods 77 are used to push the corresponding two sets of transmission slides 76 to slide symmetrically, which serves as a locking braking force to push the locking mechanism 7 to lock and close.

[0036] A locking rod 78 opposite to the insulating base mechanism 1 is provided at the bottom end of the frame of the transmission slide 76, and locking slots 14 opposite to the locking rod 78 are symmetrically provided on both sides of the insulating seat of the topmost insulating base mechanism 1.

[0037] The working principle of the present invention is as follows: when the insulating sealing device is used as the insulating protective cover of the backup battery pack of the substation, the insulating base 11 and the telescopic frame 12 in the insulating base mechanism 1 are firstly used to stretch and unfold the combination of the insulating base 11 and the telescopic frame 12 in a stretching manner, and the insulating base 11 is used as an insulating support platform, and the stretched telescopic frame 12 is used as a support platform for the backup battery pack, and the backup battery pack is placed in a modular form and on the bottom support slot 13 in the telescopic frame 12, and the modular insulation support placement work is performed on the backup battery pack;

[0038] Then, the telescopic cover 3 in the form of an accordion cover is stretched to pull the telescopic cover 3 to stretch, and the cover is placed above the modularly placed spare battery pack to provide insulation and rain protection. When the telescopic cover 3 is stretched, the combination of the first telescopic gallows 22 and the second telescopic gallows 23 in the telescopic frame mechanism 2 is driven to fold and stretch. The overall structure of the telescopic frame mechanism 2 is stretched synchronously to support and protect the telescopic cover 3, so as to avoid deformation of the telescopic cover 3 caused by external impact.

[0039] After the backup battery pack is further covered by the telescopic cover 3, the flip cover 5 is closed to form a left-right symmetrical form with the fixing platform 4, and the openings on both sides of the telescopic cover 3 are sealed, and then the backup battery pack is fully insulated and covered. When the flip cover 5 is turned over and closed, the clamping buckle 6 is turned over and clamped into the two sides of the first guide slider 25 of the telescopic frame mechanism 2, so that the first guide slider 25 is limited in sliding in the first guide slot 24, and then the first telescopic gallows 22 is limited in extension and extension, which plays a limiting and fixing function, so that the telescopic frame mechanism 2 after extension is extended and fixed, and the extension stability of the telescopic cover 3 is improved;

[0040] Further rotating the opening and closing knob 72 in the locking mechanism 7 drives the combined transmission of the bevel gear A73 and the bevel gear B74, and then drives the transmission shaft 75 and the two sets of transmission screws 77 on both sides of the shaft to rotate in combination, and the two sets of transmission slides 76 are pushed to slide symmetrically by the screw teeth arranged in positive and reverse directions on the two sets of transmission screws 77, which serve as the locking braking force, and push the corresponding locking rod 78 to be inserted into the locking slot 14, forming a locked state, so that the locking mechanism 7 and the insulating base mechanism 1 are locked as a whole, and the insulating base mechanism 1, the telescopic frame mechanism 2, the telescopic cover 3, the fixed platform 4 and the flip cover 5 are formed into an integrated extended fixed form, so as to improve the protection stability of the insulating cover;

[0041] After the spare battery pack is used up, it is only necessary to unlock the locking mechanism 7 and flip up the flip cover 5, so that the telescopic frame mechanism 2 and the telescopic cover 3 can be pushed in sequence to shrink and move the insulating base mechanism 1 toward the fixed platform 4, and the battery pack can be folded and stored for easy carrying and recycling.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
