Description

Technical Field

[0001] The utility model belongs to the field of fool-proof assembly jigs for battery stacks, and specifically relates to a fool-proof assembly jig for liquid flow battery battery stacks. Background Art

[0002] Liquid flow battery is a new type of battery. Liquid flow battery consists of a battery stack unit, electrolyte, electrolyte storage and supply unit, and management control unit. It is a high-performance battery that separates the positive and negative electrolytes and circulates them separately. It has the characteristics of high capacity, wide application range, and long cycle life. It is a new energy product.

[0003] A Chinese patent with application number CN202222113203.4 discloses a liquid flow battery stack assembly guide mechanism, including a mounting frame, a liquid flow battery stack is arranged inside the mounting frame, and a guide mechanism is arranged between the liquid flow battery stack and the mounting frame; the guide mechanism includes a sliding bar and a guide bar, and a hidden groove is opened inside the sliding bar. The external lifting equipment lifts the liquid flow battery stack up, and sliding bars are installed around the liquid flow battery stack. The sliding bars are aligned with the slide grooves on the guide bars. The sliding bars can slide to the depth of the slide grooves through rollers, and at the same time, the clamping rods on both sides of the sliding bar slide in the guide grooves through ball bearings until the liquid flow battery stack slides to the corresponding position, thereby guiding the assembly of the liquid flow battery stack. After that, the rotating shaft is rotated clockwise, and the gears will push the two clamping rods into the corresponding slots, and the sliding bar will be locked in the guide bar, thereby fixing the liquid flow battery stack after assembly. However, the liquid flow battery stack assembly guide mechanism in this application is not easy to quickly distinguish the positive and negative poles of the battery stack from the battery stack after the battery stack is lifted, which can easily cause the battery stack to be installed in the wrong direction on the mounting frame, resulting in the need for reinstallation.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a fool-proof assembly fixture for a flow battery stack.

[0009] Optionally, the two protrusions are provided with second anti-foolproof limit portions in opposite directions, and the length of the second anti-foolproof limit portions is smaller than that of the first anti-foolproof limit portions. The second anti-foolproof limit portions are slidably fitted in the limit slot, so that the second anti-foolproof limit portions, the protrusions and the first anti-foolproof limit portions form a T-shaped structure, thereby further improving the stability of the protrusions sliding in the limit slots.

[0010] Optionally, the limiting slot is a cross-shaped open slot structure, and a plurality of guide rollers are arranged in an array along the height direction on the protrusion, so as to reduce the resistance of the protrusion inserted into the limiting slot through the guide rollers.

[0011] Optionally, a chamfer is provided at the upper edge of the limit slot, so as to facilitate the insertion of the protrusion, the first anti-foolproof limit portion and the second anti-foolproof limit portion into the limit slot through the chamfer, thereby improving the convenience of inserting the protrusion, the first anti-foolproof limit portion and the second anti-foolproof limit portion into the limit slot.
