The pair of hinge supports are fixedly installed on the gate pier foundation, and the bottom shaft is hinged between them. When the gate is in a horizontal posture, the other side of the gate body opposite to the side with the bottom shaft is a free end, and the free end is supported by a door-holding device fixedly installed on the gate pier foundation;

[0007] The door holder device includes anchor bolts, pads, nuts, and supporting rubbers. The pads are fixedly installed on the gate pier foundation by anchor bolts, and the supporting rubbers are fixedly installed on the pads by bolts. The upper end surface of the supporting rubbers is flat and contacts the bottom end of the free end of the gate in a horizontal posture, and is supported on the free end of the gate in a horizontal posture by the door holder device.

[0008] The structural features of the utility model also lie in:

[0009] The pad is installed on the gate pier foundation through four anchor bolts.

[0010] The longitudinal section of the supporting rubber is convex, the step surface is fastened to the pad at four corners by four bolts, and the outer edge of the top end surface is rounded.

[0011] Compared with the prior art, the beneficial effects of the utility model are embodied in:

[0012] The utility model is used for stably supporting the free end of the gate in a horizontal posture after opening. By supporting the rubber in direct contact with the gate, wear of the gate can be avoided, the service life of the gate hoist is effectively protected, and the safety of the gate during use is guaranteed.

[0014] Figure 2 It is a schematic diagram of an application example of the utility model.

[0015] In the figure, 1 is a gate; 2 is a bottom shaft; 3 is a hinge support; 4 is a door holder device; 41 is an anchor bolt; 42 is a pad; 43 is a nut; 44 is a supporting rubber; 5 is a gate pier foundation. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0017] Please refer to Figure 1 to Figure 2 The structure of the bottom shaft driven flap gate door device of this embodiment is as follows:

[0018] The gate 1 is driven by a hoist and can swing around the hinge axis of a pair of hinge supports 3 through the bottom axis 2 on one side of the gate body, and is opened when it swings to a horizontal posture. The pair of hinge supports 3 are fixedly installed on the gate pier foundation 5, and the bottom axis 2 is hinged between them. When the gate 1 is in a horizontal posture, the other side of the gate body opposite to the side with the bottom axis 2 is a free end, and the free end is supported by a door-hanging device 4 fixedly installed on the gate pier foundation 5;

[0019] The door holder device 4 includes anchor bolts 41, pads 42, nuts 43, and supporting rubbers 44. The pads 42 are fixedly mounted on the gate pier foundation 5 by the anchor bolts 41. The supporting rubbers 44 are fixedly mounted on the pads 42 by bolts. The upper end surface of the supporting rubbers 44 is flat and contacts the bottom end of the free end of the gate 1 in a horizontal posture. The free end of the gate 1 in a horizontal posture is supported by the door holder device 4.

[0020] The corresponding structural arrangement of the device also includes:

[0021] The backing plate 42 is installed on the gate pier foundation 5 through four anchor bolts 41 .

[0022] The longitudinal section of the supporting rubber 44 is convex, the step surface is fastened to the backing plate 42 at four corners by four bolts, and the outer edge of the top surface is rounded.

[0023] When the gate 1 swings to a horizontal position and opens, in order to improve the long-term stress condition of the gate hoist and protect the service life of the gate hoist, a door rest device 4 is added to the gate pier foundation 5. The door rest device 4 supports the free end of the gate 1 in a horizontal position to meet the requirement that the gate 1 needs to remain horizontal for a long time. In the door rest device 4, the support rubber 44 is in direct contact with the gate 1, which will not cause wear to the gate 1.

[0024] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
