Description

Technical Field

[0001] The utility model relates to the field of flood control doors, in particular to a lockable flip-type flood control door with a sliding support rod. Background Art

[0002] During rainy periods, flood disasters often occur. Before the flood comes, many low-lying shopping malls, residential areas, underground garages, subways and other places need to install some flood prevention devices such as flood baffles to resist floods in order to reduce the loss of people’s lives and property.

[0003] Most of the flood prevention devices used in these existing places use a plug-in flood prevention baffle. The method of use is: on the left and right sides of the entrance and exit of the place, close to the wall, a vertical column is installed on the ground, and the side of the column has a straight groove. The flood prevention door plate is inserted into the straight groove of the columns on both sides to form a vertical water retaining surface to prevent flooding and water. Although this plug-in flood prevention baffle can play a certain role in flood prevention and water retaining, the effect is not ideal:

[0004] 1. Since flood conditions are changeable and difficult to predict, manual disassembly and assembly are often required, which is not only time-consuming and labor-intensive, but also affects the normal passage of access channels;

[0005] 2. Flood-proof door panels are large in size and difficult to carry and store;

[0006] 3. The gap between the flood control baffle and the ground is difficult to eliminate, which is prone to water seepage and leakage, and the flood control and water retaining effect is not ideal;

[0007] 4. The strength and bearing capacity of the flood control baffle are poor, and it is easy to bend and deform when preventing floods and retaining water. Additional supports are needed to strengthen the strength of the flood control baffle to avoid breakage and collapse. Utility Model Content

[0087] Below is an explanation of how a lockable flip-up flood door with a sliding support rod works:

[0088] Fig.15 This is a schematic diagram of the scene when the utility model is not flood-proof and can be passed. Fig.16 This is a schematic diagram of the scene of the utility model in flood prevention and water retention, please refer to Figures 1 to 16 As shown, a lockable flip flood-prevention door with a sliding support rod is buried in the entrance and exit passage 9 and connected to the walls 10 on both sides. When flood prevention and water blocking is needed, the staff operates the door panel handle 305 set on the door panel assembly 3 to flip the door panel assembly 3 from a horizontal passable state to a vertically upright flood prevention and water blocking state. During the flipping process, several groups of sliding support rod assemblies 5, one end of which is slidingly connected to the door panel assembly 3 and the other end is hinged to the rectangular box assembly 1, are also flipped in conjunction at the same time, from a retracted state to a state of forming a triangular support for the door panel assembly 3. When the door panel assembly 3 flips to reach the vertically upright flood prevention and water blocking state, the locking assembly 6 set on the sliding support rod assembly 5 can automatically perform a locking action to lock the triangular support formed by the sliding support rod assembly 5 on the door panel assembly 3. Under the joint action of several groups of sliding support rod assemblies 5 and the locking assembly 6, the strength and stability of the flood-prevention door are effectively improved.

[0089] When flood prevention and water blocking is not needed, the unlocking device 7 arranged on the door panel assembly 3 is rotated to release the locking support of the sliding support rod assembly 5 on the door panel assembly 3. At this time, the staff operates the door panel handle 305 again to flip the door panel assembly 3 in the opposite direction to a horizontal passable state. At the same time, several groups of support rod assemblies 5 are also flipped in conjunction and restored to the folded state, hidden inside the rectangular box assembly 1.

[0090] In addition, when the door panel assembly 3 is flipped to a vertically upright flood-prevention and water-blocking state, the bottom sealing rubber strip 302b arranged on the door panel assembly 3 and the bottom sealing pressing plate 103 on the rectangular box assembly 1 abut against and press against each other, so that a good seal is formed at the bottom of the flood-prevention door. At the same time, the side sealing rubber strips 303b arranged on the left and right sides of the door panel assembly 3 respectively abut against and press against the side sealing pressing plates 202 arranged on the fixed column assembly 2 on the same side, so that a good seal is also formed on the left and right sides of the flood-prevention door. Therefore, the flood-prevention door also has a good sealing and water-blocking effect.

[0091] The above description is only a preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model. For those skilled in the art, any equivalent replacement and obvious modification made by using the description and illustrations of the utility model should be included in the protection scope of the utility model.
