DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that, in the description of the present invention, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] In addition, it should be understood that for the convenience of description, the sizes of various components shown in the drawings are not drawn according to the actual proportional relationship.

[0025] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not require further detailed discussion and description in the description of the subsequent drawings.

[0026] Before understanding the present invention, it should be clear that tunnel flood prevention doors are generally provided with a bus bar for supplying power to trains. When the tunnel flood prevention doors are closed, the bus bar is often hindered from closing. If the tunnel flood prevention doors are forcibly closed, the bus bar will be squeezed and damaged. Therefore, in general, in order to protect the bus bar, the bus bar must be disconnected before the tunnel flood prevention doors are closed. This operation not only increases the workload of the staff, but also correspondingly prolongs the closing time of the tunnel flood prevention doors.

[0027] like Figures 1 to 5 As shown, the utility model provides a technical solution: a fully automatic subway tunnel flood prevention door, wherein the tunnel flood prevention door comprises a door frame 1, a large door leaf 2, a small door leaf 3, a busbar sealing device 4 and a control system 5.

[0028] Specific as Figure 1 and Figure 2 As shown, the door frame 1 in the tunnel flood prevention door is fixed on the inner wall of the subway tunnel, and the door frame 1 includes an upper door frame 11 and a lower door frame 12 arranged opposite to each other up and down, and a large door leaf door frame 13 and a small door leaf door frame 14 arranged opposite to each other left and right, and the upper door frame 11, the lower door frame 12, the large door leaf door frame 13 and the small door leaf door frame 14 are fixedly connected end to end in sequence.

[0029] like Figure 1 and Figure 3 As shown, the large door leaf 2 includes a large door leaf body 21, a hydraulic drive device 24 and a large door leaf hinge mechanism 23, wherein one end of the large door leaf body 21 is connected to the large door leaf door frame 13 through the large door leaf hinge mechanism 23, one end of the hydraulic drive device 24 is connected to the large door leaf body 21, and the other end is connected to the inner wall of the subway tunnel, the hydraulic drive device 24 can drive the large door leaf body 21 to rotate around the large door leaf hinge mechanism 23 to realize the opening or closing of the large door leaf body 21, and a bus groove 22 is provided on the large door leaf body 21, the opening of the bus groove 22 is oriented away from the large door leaf door frame 13, and the opening of the bus groove 22 is oriented perpendicular to the axial direction of the large door leaf hinge mechanism 23.

[0030] Furthermore, the door hinge mechanism 23 is welded to the door frame 13 of the door by means of a plurality of angle steels, and its hydraulic drive device 24 connected to the door body 21 includes a hydraulic cylinder 24A, a hydraulic piston rod 24B and a mounting fixed base 24C, the hydraulic cylinder 24A is electrically connected to the control system 5, one end of the hydraulic piston rod 24B is slidably connected to the hydraulic cylinder 24A, and the other end of the hydraulic piston rod 24B is fixedly connected to the door body 21 by means of a mounting fixed base 24C.

[0031] like Figure 1 and Figure 4 As shown, the small door leaf 3 includes a small door leaf body 31, a hydraulic drive device 23 and a small door leaf hinge mechanism 32. One end of the small door leaf body 31 is connected to the small door leaf door frame 14 through the small door leaf hinge mechanism 32. One end of the hydraulic drive device 23 is connected to the small door leaf body 31 and the other end is connected to the inner wall of the subway tunnel. The hydraulic drive device 23 can drive the small door leaf body 31 to rotate around the small door leaf hinge mechanism 32 to realize the opening or closing of the small door leaf body 31. At the same time, when the small door leaf body 31 and the large door leaf body 21 are both closed, one end of the small door leaf body 31 away from the small door leaf hinge mechanism 32 can enclose the opening of the bus slot 22 so that the bus slot 22 forms a bus hole, and the bus 9 can pass through the bus hole.

[0032] Furthermore, the small door hinge mechanism 32 is welded to the small door frame 14 by multiple angle steels, and its hydraulic drive device 33 connected to the small door body 31 includes a hydraulic cylinder 33A, a hydraulic piston rod 33B and a mounting fixed base 33C.

[0033] Furthermore, in addition to the above-mentioned technical solution for the position setting of the bus slot 22 in the embodiment of the utility model, there are two other technical solutions for the position setting of the bus slot 22: the bus slot 22 is separately set on the small door leaf body 31 or the bus slot 22 is simultaneously set on the large door leaf body 21 and the small door leaf body 31; wherein: when the bus slot 22 is separately set on the small door leaf body 31, the opening of the bus slot 22 is oriented away from the small door leaf door frame 14, and the opening of the bus slot 22 is oriented perpendicular to the axial direction of the small door leaf hinge mechanism 32. At the same time, when the small door leaf body 31 and the large door leaf body 21 are both closed, the end of the large door leaf body 21 away from the large door leaf hinge mechanism can enclose the opening of the bus slot 22 opened in the small door leaf body 31 so that the bus slot 22 forms a bus hole, and the bus 9 can pass through the bus hole; similarly, when the bus slot 22 is simultaneously set on the large door leaf body 21 and the small door leaf body 3 1, at this time, when the large door leaf body 21 and the small door leaf body 31 are both closed, the opening directions of the two bus bar grooves 22 respectively arranged on the large door leaf body 21 and the small door leaf body 31 are opposite, and the opening directions of the two bus bar grooves 22 are respectively perpendicular to the axial direction of the large door leaf hinge mechanism 23 and the small door leaf hinge mechanism 32. When the small door leaf body 31 and the large door leaf body 21 are both closed, the two bus bar grooves 22 can cooperate to form a bus bar hole, and the bus bar 9 passes through the bus bar hole; in the above three technical schemes for the position setting of the bus bar groove 22, when the large door leaf body 21 and the small door leaf body 31 are opened and closed, the rotation of the large door leaf body 21 and the small door leaf body 31 can completely avoid the bus bar 9 through the bus bar groove 22 arranged therein, which effectively solves the disadvantage that the bus bar 9 needs to be disconnected when the tunnel flood prevention door is opened and closed, which not only effectively reduces the opening and closing time of the tunnel flood prevention door, but also saves the operation of disconnecting the bus bar 9 by the staff.

[0034] like Figure 1 and Figure 5As shown, the bus sealing device 4 includes a plurality of door leaf sealing devices connected to the large door leaf body 21 and the small door leaf body 31 and a driving hydraulic motor adapted to the door leaf sealing devices.

The guide device 73 can be used to provide guidance for the up and down movement of the sealing beam 71.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the tunnel flood prevention door also includes a door leaf positioning device 8, which includes a large door leaf positioning device 81 and a small door leaf positioning device 82, wherein: the large door leaf positioning device 81 is installed on the large door leaf body 21, and the large door leaf positioning device 81 includes a large door leaf positioning hydraulic cylinder 81A and a large door leaf positioning base 81B, the large door leaf positioning hydraulic cylinder 81A is connected to the control system 5 by electrical signals, and the large door leaf positioning hydraulic cylinder 81A can be used to drive the large door leaf positioning base 81B to position and lock the large door leaf 2; the small door leaf positioning device 82 is installed on the small door leaf 3, and the small door leaf positioning device 82 includes a small door leaf positioning hydraulic cylinder 82A and a small door leaf positioning base 82B, the small door leaf positioning hydraulic cylinder 82A is connected to the control system 5 by electrical signals, and the small door leaf positioning hydraulic cylinder 82A can be used to drive the small door leaf positioning base 82B to position and lock the small door leaf 3.
