Description

Technical Field

[0002] As an outstanding representative of modern flood control technology, water-retaining (flood-proof) electric gates are designed to cope with rainstorms and floods in extreme weather. The gates integrate advanced intelligent control technology with a sturdy and durable physical structure to protect key facilities from floods. It is widely used in places such as substations, grain depots, machine rooms, storage and logistics parks, and underground garages. These areas are not only densely populated with people and logistics, but are often in low-lying areas and face higher flood risks. Through rapid response and efficient waterproofing, while ensuring unobstructed passages, it also provides a solid barrier for the safety of the facilities. With the intensification of global climate change, extreme weather events occur frequently, especially natural disasters such as rainstorms and floods, which have a serious impact on human society and economic activities.

[0003] General flood control facilities are mostly concentrated in the gate systems of water conservancy projects such as rivers and reservoirs. Their main function is to regulate water flow and prevent flooding. However, traditional flood control measures often seem powerless in the face of sudden floods, especially at the gates of key facilities such as substations, grain depots, machine rooms, storage and logistics parks, and underground garages. These areas are more vulnerable to floods due to frequent flow of people and logistics and are often located in low-lying areas.

The bottom of the lower door rails 12 close to the water retaining plate 3 is provided with an arc storage groove. The rectangular door body 2 is the main structural part, and its design details are crucial to the realization of the flood control function. The transmission rack 11 fixedly connected to the bottom of the side of the door body away from the water retaining plate 3 is an important component connecting the door opening drive motor and the door body.

The threaded rod passes through the fixed block 13 and is threadedly connected to it, and its lower end is threadedly connected to the movable connecting block 31. With the rotation of the threaded rod, the movable connecting block 31 moves in the vertical direction, and then drives the water baffle to rise and fall through the water baffle connecting piece 15, ensuring that the water baffle can move flexibly with the opening and closing of the rectangular door body, achieving close fit and release with the ground and the closing and opening posts, forming a reliable waterproof barrier.

The water baffle connecting member 14 and the water baffle connecting member 2 15 are rotatably connected at the inflection point. By rotatably connecting the water baffle connecting member 14 and the water baffle connecting member 2 15 at the inflection point, the water baffle can automatically adjust its angle during the lifting process to ensure a close fit with the ground and the closing and opening door columns, thereby achieving a better waterproof effect.

[0046] Furthermore, the water baffle supporting structure includes an arc-shaped mounting block 18, an arc-shaped movable groove 19, a strip sliding groove 20 and a supporting foot 21. The water baffle 3 is fixedly connected to the lower end of one side close to the rectangular door body 2 with an arc-shaped mounting block 18. An arc-shaped movable groove 19 is provided on one side of the arc-shaped mounting block 18. The side of the arc-shaped mounting block 18 is an arc-shaped structure. A plurality of equally spaced strip sliding grooves 20 are provided on the side of the arc-shaped mounting block 18. The strip sliding grooves 20 are connected to the arc-shaped movable grooves 19. As the main supporting component of the water baffle, the arc-shaped mounting block 18 is fixedly connected to the lower end of one side of the water baffle 3 close to the rectangular door body 2. Its arc-shaped design not only matches the shape of the water baffle, but also enhances the stability and bearing capacity of the supporting structure. The arc-shaped structure of the side of the arc-shaped mounting block 18 helps to provide smooth guidance during the lifting and lowering of the water baffle, reducing friction and resistance; the arc-shaped moving groove 19 provides the necessary space for the lifting and lowering of the water baffle, which allows the water baffle to move freely in the vertical direction while maintaining a close fit with the ground and the closing and opening columns; the strip sliding groove 20 provides a sliding track for the supporting foot 21 of the water baffle, and the supporting foot 21 provides additional support for the water baffle by being inserted into the strip sliding groove 20 and in contact with the ground.

The side of the supporting foot 21 close to the arc-shaped mounting block 18 is an arc surface that fits the side of the arc-shaped mounting block 18. The lower end of the side of the water baffle 3 close to the rectangular door body 2 is fixedly connected to the side of the arc-shaped mounting block 18. The moving rod 22 is fixedly connected to the push rod of the electric push rod 23. A plurality of arc-shaped blocks 25 matching the strip sliding grooves 20 are movably connected in the inner cavity of the arc-shaped moving groove 19.

[0048] Furthermore, a supporting foot movable fixing groove 24 is provided on one side of the arc-shaped clamping block 25 close to the supporting foot 21. The two ends of the supporting foot movable fixing groove 24 are horizontal grooves and are located at the diagonal ends of the arc-shaped clamping block 25. The two ends of the supporting foot movable fixing groove 24 are designed to be horizontal grooves and are located at the diagonal ends of the arc-shaped clamping block 25. This structural layout enables the supporting foot to be precisely embedded in the groove when sliding to a specific position, thereby achieving stable fixation.

[0049] Furthermore, the flood control door drive device includes a door opening drive motor 26, a power module 27, a control circuit board 28 and a gear 29. The door opening drive motor 26 is fixedly connected to the bottom of the inner cavity of the control box 8, and the rotating shaft of the door opening drive motor 26 extends to the outside of the control box 8 and is fixedly connected to the gear 29. The gear 29 is meshed with the transmission rack 11. The control circuit board 28 is fixedly connected to the top of the inner cavity of the control circuit board 28. The power module 27 is fixedly connected between the corresponding control circuit board 28 and the power module 27 in the inner cavity of the control box 8. The water baffle drive motor 16, the electric push rod 23, the door opening drive motor 26 and the power module 27 are all electrically connected to the control circuit board 28. The door opening drive motor 26 serves as a power source, and the smooth opening and closing of the flood control door is achieved through the meshing of the gear 29 and the transmission rack 11. The power module 27 provides a reliable power supply for the entire system to ensure the normal operation of each component. The control circuit board 28 adopts the Siemens S7-1200 series PLC as the core control unit. With its high reliability, strong anti-interference ability and flexible programming characteristics, it is responsible for receiving external commands, processing signals, and accurately controlling the actions of actuators such as the door opening drive motor 26, the water baffle drive motor 16 and the electric push rod 23. The rich interfaces and easy programming and debugging of the Siemens S7-1200 series PLC enable the control system of the flood control door device to be highly integrated and customized, ensuring stable operation even in harsh environments, effectively preventing the entry and backflow of foreign water, and ensuring the safety of low-lying areas and important facilities.

[0050] Working principle: The core of this device lies in its ingeniously designed structure and intelligent control system. First, two solid doorposts 1 are symmetrically fixed to the ground. They are not only the support points of the entire structure, but also ensure the stable operation of the door body 2. The door body 2 adopts a rectangular design, and a number of precise moving pulleys are installed at the bottom. These pulleys slide along the preset sliding track 5, so that the opening and closing of the door body are both smooth and fast. The protective wall 4 is an auxiliary structure, which is fixedly connected to one side of the doorpost, which not only enhances the stability of the overall structure, but also blocks external impact to a certain extent, providing additional safety for flood control.

[0051] When a flood prevention instruction is received, the flood prevention door drive device starts immediately. The door opening drive motor 26 in the control box 8 serves as a power source. Its powerful torque is transmitted to the gear 29 through the transmission system. The gear is tightly engaged with the transmission rack 11, driving the door body 2 to move slowly in the closing direction along the sliding track 5. At the same time, the power module 27 provides a stable power supply for the entire system, and the control circuit board 28 serves as the "brain", responsible for receiving external signals, processing data, and accurately controlling the coordinated actions of various components.

[0052] During the closing process of the door body 2, the connection mechanism begins to play its key role. The water baffle driving motor 16 starts after receiving the signal, and drives the movable connection block 31 to rise by rotating the threaded rod 17. This action causes the V-shaped structure of the water baffle connecting piece 14 and the water baffle connecting piece 2 15 to gradually unfold until the water baffle 3 fits tightly between the door body 2 and the ground. At this time, the sealing strip 1 6 and the sealing strip 2 7 are effectively compressed to form an indestructible waterproof barrier. These silicone rubber strips not only have good sealing performance, but can also be further deformed when under pressure, ensuring that the waterproof effect can be maintained at any water level.

[0053] In order to ensure the stability of the water retaining plate 3 during flood prevention, the water retaining plate support structure begins to play its role. The arc-shaped moving groove 19 and the strip sliding groove 20 on the arc-shaped mounting block 18 provide flexible adjustment space for the moving rod 22 and the sliding clamping column 30. As the water level rises, the electric push rod 23 adjusts the extension length of the support foot 21 according to the preset program or real-time water level data, so that the water retaining plate always maintains a stable support state. At the same time, the arc surface design of the support foot 21 fits tightly with the side of the arc-shaped mounting block 18, further enhancing the stability and waterproof performance of the structure. This dynamic adjustment mechanism ensures that the water retaining plate can maintain the best working state at different water levels.

[0054] When the flood recedes and the gate needs to be opened, the flood control door drive device works in the reverse direction. The door opening drive motor 26 drives the gear 29 to rotate in the reverse direction, driving the door body 2 to move in the opening direction along the sliding track 5. At the same time, the components in the connecting mechanism are reset under the drive of the motor, the water retaining plate 3 is lifted and retracted to the initial position, and the normal traffic state of the gate is restored.

[0055] During the whole process, the control circuit board 28 always monitors the working status of each component to ensure that all actions are executed accurately according to the preset procedures. This intelligent control system not only improves the reliability and stability of the flood-proof electric gate, but also greatly simplifies the operation process and reduces labor costs.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art 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 appended claims and their equivalents.
