[0009] Preferably, the shielding board is located in front of the warning board.

[0010] Preferably, the material of the warning board is PP plastic.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are as follows

[0012] 1. In the present utility model, when the electric rolling shutter door is unfolded, it can be embedded in the groove, greatly improving the sealing performance of the garage door, preventing rainwater from seeping into the garage through the gaps, enhancing the overall waterproof ability. And when the electric rolling shutter door is unfolded and embedded in the groove, by pressing down the vertical rod, the hydraulic system is triggered, causing the connecting rod to drive the step to rise. This linkage mechanism ensures that when the rolling shutter door is closed, the step automatically extends out, forming multiple layers of protection to further prevent rainwater from flowing back into the garage. Moreover, the step can not only further block rainwater but also act as a barrier to foreign objects such as stones, protecting the electric rolling shutter door from being damaged by external hard objects, thereby improving the anti-flood effect of the present utility model. Using the step made of aluminum alloy material not only ensures the strength and durability of the step but also improves the stability and anti-impact ability in harsh environments.

[0013] 2. In the present utility model, rainwater can make the buoy float, thus raising the trigger warning board. This design can automatically remind the surrounding people of the danger during floods without manual operation or power support, effectively improving safety and response speed. And after the warning board rises, it is higher than the shielding board, ensuring that it can be clearly seen by the people and drivers in front, timely reminding them of the occurrence of floods and that the garage door has been urgently closed, avoiding entering the garage by mistake and preventing possible accidents. By using rainwater to naturally lift the buoy, without the need for electricity or complex sensor systems, the maintenance cost and failure risk are greatly reduced, which is especially suitable for occasions where the function still needs to be normal when the power is interrupted or the equipment fails.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-5The utility model provides a technical solution: a garage backflow prevention device, comprising a garage door 1, and an electric rolling door 2 is fixedly installed on the top surface of the garage door 1. The installation of the electric rolling door 2 can be achieved by bolt connection, welding or flange connection, among which the bolt connection method has the characteristics of convenient disassembly and easy maintenance, and is suitable for occasions that require frequent maintenance; the welding method has high connection strength and sealing, and can effectively prevent rainwater from seeping from the interface; the flange connection has the advantages of convenient installation and high strength, and is particularly suitable for environments that need to withstand large external forces or vibrations. The main function of the electric rolling door 2 is to close quickly when floods occur, thereby preventing rainwater from backflowing from the garage door 1 into the interior of the garage, and serving as the first line of defense. A groove 3 and an installation groove 4 are provided on the inner side of the garage door 1. A vertical rod 5 is provided through the inner wall of the groove 3, and the sliding connection method of the vertical rod 5 can adopt a ball guide or a linear bearing. The ball guide has the characteristics of low friction and high precision, which can ensure that the vertical rod 5 moves smoothly and accurately in the vertical direction, so that when the electric rolling door 2 is pressed down, it can quickly respond and start the subsequent flood control mechanism; the linear bearing has the advantages of wear resistance and long life, and is suitable for use in high-frequency use environments. The main function of the vertical rod 5 is to withstand the downward pressure of the door body during the closing process of the electric rolling door 2, and transmit this pressure to the piston 8 installed at its bottom. The piston 8 realizes the linkage of the hydraulic system by squeezing the hydraulic fluid in the cylinder 10, and further triggers the rise of the connecting rod 7 and the step 6. The inner wall of the mounting groove 4 is slidably connected with a step 6, and the material of the step 6 is aluminum alloy. In outdoor or humid environments, aluminum alloy can maintain its structural strength and appearance for a long time. The sliding connection of the step 6 can adopt a T-type slide groove. The design of the T-type slide groove can prevent the step 6 from leaving the track when it is stressed, ensuring that it always moves along the predetermined trajectory. The function of the step 6 is to rise and protrude to the outside of the bottom of the garage door 1 under the drive of the hydraulic system, forming a second line of defense, further blocking possible floods, and forming a physical barrier to floating objects such as stones, protecting the electric rolling door 2 from damage. A connecting rod 7 is fixedly installed on the bottom surface of the step 6, and a piston 8 is fixedly installed at the bottom end of the connecting rod 7 and the vertical rod 5. The connection between the connecting rod 7 and the piston 8 can be threaded, interference fit or welded. The threaded connection method can facilitate later disassembly and maintenance, especially when the piston 8 or the connecting rod 7 needs to be replaced. It shows strong convenience; the interference fit can achieve high-strength and high-reliability fixation through precision machining, which is suitable for high-load working environments; the welding fixation can provide a permanent connection, which is suitable for those parts that do not need to be frequently disassembled. The function of the piston 8 is to convert the pressure into the hydraulic fluid pressure inside the cylinder 10 when the vertical rod 5 moves downward under force, thereby driving the connection rod 7 and the step 6 to rise.

[0025] See also Figures 1-5, an installation bracket 9 is fixedly installed on the bottom surface of the garage door 1. The installation bracket 9 is in an "L" - shaped structure. This structural design can provide a larger support surface, thereby dispersing the stress at the bottom of the garage door 1 and improving the stability of the overall structure. The connection method of the installation bracket 9 can be bolt connection, welding or adhesive fixation. Among them, the bolt connection method is convenient for maintenance and replacement, the welding method can provide a more firm fixation effect, and the adhesive fixation is suitable for use in occasions where drilling is not allowed or there is high - intensity vibration. A cylinder 10 is fixedly installed on the side of the installation bracket 9. The inside of the cylinder 10 is filled with hydraulic fluid. The shape of the cylinder 10 is "J" - shaped. This design can better cooperate with the structure of the installation bracket 9, making the cylinder 10 closely fit the bottom of the garage door 1. The function of the cylinder 10 is to drive the rising of the connecting rod 7 and the step 6 through the linkage of the hydraulic system during floods, so as to achieve the function of preventing backflow. The hydraulic fluid inside the cylinder 10 is selected as hydraulic oil with high fluidity and oxidation resistance to ensure that during long - term use, the hydraulic system can maintain stable performance and reduce the replacement frequency of the hydraulic fluid.

[0026] Embodiment Two

[0027] Please refer to Figures 4-5, a prompting mechanism is provided on the side of the garage door 1. The prompting mechanism includes a vertical groove 11 which is opened on the side of the garage door 1, and a slider 12 is slidably connected to the inner wall of the vertical groove 11. The slider 12 can adopt connection methods such as a guiding slide rail or a ball slideway. The guiding slide rail can ensure that the slider 12 moves along a predetermined path and avoids deviation during the lifting process; the ball slideway can make the slider 12 move more easily and smoothly in the vertical groove 11 by reducing the friction force. One end of the slider 12 is fixedly installed with a warning board 13, and the material of the warning board 13 is PP plastic. The PP plastic material has the characteristics of light weight, impact resistance and corrosion resistance, and is very suitable for use outdoors or in humid environments. The main function of the warning board 13 is to drive the warning board 13 to rise through the rise of the buoy 14 during a flood, so as to transmit a warning signal to the outside world and remind people to pay attention to the flood danger and the closed state of the garage door 1. A buoy 14 is fixedly installed on the bottom surface of the warning board 13, and the buoy 14 is connected to the warning board 13 by bonding, embedding or buckling. The bonding method can ensure the sealing performance between the buoy 14 and the warning board 13, the embedding method can make the buoy 14 and the warning board 13 more closely combined, and the buckling method provides the convenience of installation and disassembly. The main function of the buoy 14 is to drive the warning board 13 to rise through its own buoyancy when rainwater floods into the vertical groove 11. This design utilizes the principle of natural buoyancy, which not only saves electric power resources but also avoids a complex sensor system, greatly reducing the maintenance cost and failure rate of the device. A baffle 15 is fixedly installed on the side of the garage door 1, and the baffle 15 is located in front of the warning board 13. The baffle 15 can be fixedly connected to the garage door 1 by bolts, welding or embedding. The bolt connection method is convenient for replacement, the welding method provides higher fixing strength, and the embedding method enables the baffle 15 to be more closely combined with the garage door 1, avoiding the decline of the sealing performance caused by gaps. The main function of the baffle 15 is to block the warning board 13 during non-flood periods, making it in a hidden state to prevent false triggering or damage by the outside world. At the same time, the baffle 15 also ensures that when the buoy 14 floats and rises to a predetermined height, the warning board 13 can effectively cross the baffle 15 and send out an obvious warning signal to the outside, reminding the surrounding people and drivers of the occurrence of the flood and the emergency closure of the garage door 1.

[0028] Working principle: During floods, the staff can open the electric rolling door 2. At this time, the electric rolling door 2 unfolds, thus closing the garage door 1, and further preventing rainwater from flowing back into the garage. When the electric rolling door 2 unfolds, it can be embedded in the groove 3, which can improve the sealing performance. At the same time, it can squeeze the vertical rod 5 downward. During the downward movement of the vertical rod 5, the hydraulic fluid in the oil cylinder 10 can be squeezed through the piston 8. At this time, the hydraulic fluid can drive the connecting rod 7 to move upward. Subsequently, the connecting rod 7 can drive the step 6 to slide upward in the installation groove 4. At this time, the step 6 automatically extends. Through the step 6, rainwater flowing back can be further prevented. At the same time, the step 6 can also play a protective role. The step 6 made of aluminum alloy material is relatively strong and can block foreign objects such as stones, thus preventing the electric rolling door 2 from being damaged by the impact, and improving the flood resistance effect. In the present utility model, when the electric rolling door 2 unfolds, it can be embedded in the groove 3, greatly improving the sealing performance of the garage door 1, preventing rainwater from seeping into the garage through the gaps, and enhancing the overall waterproof ability. And when the electric rolling door 2 unfolds and is embedded in the groove 3, by squeezing the vertical rod 5 downward, the hydraulic system is triggered, so that the connecting rod 7 drives the step 6 to rise. This linkage mechanism ensures that while the rolling door is closed, the step 6 automatically extends, forming a multi-layer protection to further prevent rainwater from flowing back into the garage. The step 6 can not only further block rainwater, but also play a role in blocking foreign objects such as stones, protecting the electric rolling door 2 from being damaged by the impact of external hard objects, thus improving the flood resistance effect of the present utility model. Using the aluminum alloy material for the step 6 not only ensures the strength and durability of the step 6, but also improves the stability and impact resistance ability in harsh environments. During floods, the rainwater can make the buoy 14 float. Subsequently, the buoy 14 can drive the warning board 13 to move upward. The warning board 13 can drive the slider 12 to slide in the vertical groove 11. At this time, the warning board 13 extends upward and is higher than the shielding board 15. In this way, the warning board 13 can be seen by the personnel in front, thus reminding the personnel to pay attention to the flood. At the same time, it can also remind the incoming vehicles that the garage door 1 has been closed emergently and not to drive forward. In the present utility model, the rainwater can make the buoy 14 float, thus triggering the warning board 13 to rise. This design can automatically remind the surrounding personnel of the danger during floods without manual operation or power support, effectively improving the safety and response speed. And after the warning board 13 rises, it is higher than the shielding board 15, ensuring that it can be clearly seen by the personnel and drivers in front, timely reminding them of the occurrence of the flood and that the garage door 1 has been closed emergently, avoiding entering the garage by mistake and preventing possible accidents. By using the rainwater to naturally lift the buoy 14, without power or complex sensor systems, the maintenance cost and failure risk are greatly reduced, which is especially suitable for occasions where the function needs to be ensured to be normal even in case of power interruption or equipment failure.

[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
