[0033] The bottom angle steel 3 is welded to the wall reinforcement at the wall entrance and wall and concrete is poured to form the lower door frame, which is a 50*25 rectangular square tube.

[0034] The top angle steel 2 is welded to the wall reinforcement at the wall entrance and wall frame based on the internal reinforcement and concrete is poured to form the upper door frame;

[0035] Both side angle steel 1 are welded to the internal rebar and the rebar on both sides of the wall entrance and exit and then poured with concrete to form the door frames on both sides. The upper door frame and the two side door frames are both 50*50 square tubes.

[0036] The door panel consists of two sets of wide door panels 7 and two sets of hinges 8. The two sets of wide door panels 7 are symmetrically distributed from left to right. The two sets of wide door panels 7 are connected to the two sides of the door frame by two hinges 8 on the side that is far apart from each other.

[0037] The number of each set of wide door bodies 7 is multiple, and the multiple wide door bodies 7 are connected by three hinges. The upper hinge is equipped with an upper guide wheel 91 through a bearing. The upper guide wheel 91 is located in the upper guide rail 4 and is slidably connected to the upper guide rail 4. The lower hinge is equipped with a lower guide wheel 9 through a bearing. The lower guide wheel 9 is located in the lower guide rail 6 and is slidably connected to the lower guide rail 6.

[0038] The door frame and each set of door leaves are connected and sealed by sealing strip 10, each wide door body 7 is connected and sealed by sealing strip 2 11, and the two sets of door leaves are connected and sealed by sealing strip 3 12.

[0039] Each wide door 7 is provided with a lock hole 71 and a locking assembly 13, which includes an upper locking head 14, a lower locking head 15 and a crank handle 200.

[0040] A lower base box 16 is installed on both the top angle steel 2 and the bottom angle steel 3. The lower base box 16 is adapted to the upper locking head 14 and the lower locking head 15.

[0041] The working principle of the folding floodproof door provided by this utility model is as follows:

[0042] First step: During the unfolding operation, the operator pushes the wide door body 7. Since the multiple wide door bodies 7 are connected by hinges, and the upper guide wheel 91 slides in the upper guide rail 4 and the lower guide wheel 9 slides in the lower guide rail 6, under the cooperation of the guide wheel and the guide rail, the multiple wide door bodies 7 in the folded state can unfold along the direction of the guide rail. The two sets of wide door bodies 7 are symmetrically distributed on the left and right. The side that is far away from each other is connected to the two sides of the door frame through the hinge. During the unfolding process, the hinge 8 also rotates to assist the wide door body 7 in unfolding into place.

[0043] Second step: After the wide door 7 is fully opened, turn the crank 200 of the locking assembly 13 on each wide door 7 so that the upper locking head 14 and the lower locking head 15 are inserted into the lower bottom box 16 on the top angle steel 2 and the bottom angle steel 3 respectively, thereby fixing the wide door 7 to the door frame and completing the closing and locking of the floodproof door. At this time, the sealing strips between the door frame and the door leaf, the wide door 7 and the two sets of door leaves are tightly fitted to achieve a seal.

[0044] Third step: When folding and storing, turn the crank handle 200 in the opposite direction to disengage the upper locking head 14 and the lower locking head 15 from the lower bottom box 16 to unlock them. Then push the wide door body 7 in the opposite direction. With the sliding cooperation of the guide wheel and the guide rail and the action of the hinge, the multiple wide door bodies 7 fold together and are finally stored on both sides of the door frame to reduce space occupation.
