Description

Technical Field

[0001] The invention belongs to the technical field of safety flood control doors, and in particular relates to an underground flood control door. Background Art

[0002] During the rainy season, some communities in low-lying areas of cities often experience rainwater backflow during heavy rains, causing serious damage to vehicles in the community's underground garage. In the existing community flood control, flood control sandbags are usually piled up at the entrance of the underground garage to increase the flood control height to prevent flooding. This flood control method has the following shortcomings: when extreme weather occurs, the amount of rainfall will increase significantly in a short period of time, especially at night. If people do not react quickly enough, a deeper water accumulation area will soon be formed, and once it pours into the underground garage, it will be difficult to block it. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an underground flood control door.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is: An underground flood control door comprises a fixed bracket, an opening and closing component, a barrier component, and a water storage control component. The fixed bracket is fixedly connected to a wall, the opening and closing component is fixedly connected to the fixed bracket, a barrier component is provided on one side of the opening and closing component, and a water storage control component is provided at the bottom of the barrier component. When urban waterlogging occurs, flood water is allowed to enter the water storage control component. When the water level reaches a certain height in the water storage control component, a signal is sent inside, and the signal is transmitted to a computer. The opening and closing component is controlled by the computer, so that the opening and closing component controls the barrier component to block the flood water.

[0005] Preferably, the opening and closing assembly includes an electric push cylinder, a push-pull rod, a U-shaped frame, and a connecting rod. The tail end of the electric push cylinder body is rotatably connected to a fixed bracket via an axis, the top end of the electric push cylinder is connected to the push-pull rod via an axis, the other end of the push-pull rod is connected to the fixed bracket via an axis, the middle part of the push-pull rod is connected to the U-shaped frame via an axis, the bottom of the U-shaped frame is fixedly connected to a connecting rod, and the bottom of the connecting rod is connected to the barrier assembly via an axis. When the electric push cylinder receives a signal, the output end of the electric push cylinder continuously pushes out to push the push-pull rod to rotate downward. During the downward rotation of the push-pull rod, the U-shaped frame is simultaneously controlled to drive the connecting rod to drive the barrier assembly to move downward.

[0006] Preferably, the barrier assembly includes a door body, a buffer rod, a baffle plate, and a door frame, wherein the door frame is fixedly connected to the wall, the top of the door body is connected to the connecting rod through an axis, the door body is slidably connected inside the door frame, buffer rods are fixedly provided on both side walls of the door body, and baffle plates are fixedly provided on the bottom of the buffer rods. When the door body moves downward along the door frame, the buffer rods on both sides of the door body move downward synchronously, and the baffle plates can increase the contact area with water, thereby making the door body more stable during its downward sliding process.

[0007] Preferably, the door body includes springs, rubber plates, barbs, and grooves. A plurality of springs are fixedly arranged inside the door body. A rubber plate is fixedly arranged on one side of the spring. A groove is provided on each of the two side walls at the bottom of the rubber plate. A barb is fixedly arranged on the bottom of the door body. The barb is placed inside the groove. During the descending process of the door body, the rubber plate will compress the spring after contacting the ground, causing the spring to undergo elastic deformation, which in turn reacts to the rubber plate, so that the rubber plate is sealed and fits against the ground to prevent water from entering. The rubber plate can be fixed to the inside of the door body by the barb to prevent it from falling off.

[0008] Preferably, the water storage control component includes a water tank, a water guide pipe, a guide block, a floating plate, a signal receiver, and a signal generator. The two side walls of the water tank are each connected to a water guide pipe. A guide block is fixedly provided at the bottom of the water tank, a floating plate is provided in the middle of the water tank, a signal generator is fixedly provided on the floating plate, and the signal receiver is fixedly provided on the inner wall of the water tank. When water flows into the water tank through the water guide pipe, the water flow will impact the guide block, so that the water flow tends to be stable. As the water level continues to rise, the floating plate continues to rise with the water level until the signal generator on the floating plate contacts the signal receiver. At this time, the water level height signal is transmitted to the computer, and the signal is further processed and output by the computer.

[0009] Preferably, the guide block includes a drainage channel, an arc top section, and an inclined straight plate. A plurality of drainage channels are provided at the bottom of the guide block. The top section of the guide block is an arc top section, and one side of the arc top section is an inclined straight plate. When the water flow impact is strong, the water flow is buffered by the arc top section, so that the water flow entering the water tank is relatively stable.

[0010] Preferably, a grate is fixedly provided on the top of the water conduit, and water flows into the water conduit through the grate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: A water tank is set up underground to monitor the ground water level. When the water level in the water tank continues to rise, the floating board is driven to rise. When the signal generator on the floating board contacts the signal receiver fixed on the side wall of the water tank, the signal is transmitted to the computer. After the signal is processed in the computer, it is converted into a signal to control the electric push cylinder for output, so that the electric push cylinder is continuously pushed out, pushing the push-pull rod to rotate downward. During the downward rotation of the push-pull rod, the U-shaped frame is controlled to drive the connecting rod to drive the door body to move downward. During the downward movement of the door body, the buffer rods on both sides of the door body move downward synchronously. The impact plate can increase the contact area with water, so that the door body can slide more smoothly in the process of sliding downward. When the door body is about to contact the ground, the rubber plate contacts the ground first. After the rubber plate contacts the ground, it compresses the spring, causing the spring to undergo elastic deformation, and then reacts to the rubber plate, so that the rubber plate and the ground are sealed and fit to prevent water from entering.

[0012] The water level can then be automatically monitored and controlled to prevent the water level from rising too quickly and being too late to handle. BRIEF DESCRIPTION OF THE DRAWINGS
