[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figure 1 and Figure 2 As shown, the flood control door 100 of an embodiment of the present invention includes a wall 1, a door body 2, a driving device 3, a water level monitoring device 4 and a controller 5. The door body 2 is slidably connected to the wall 1; the driving device 3 is used to control the sliding of the door body 2 relative to the wall 1 so that the door body 2 switches between an open mode and a closed mode; the water level monitoring device 4 is connected to the door body 2 or the wall 1 to monitor the water level through the water level monitoring device 4; the water level monitoring device 4 and the driving device 3 are both electrically connected to the controller 5.

[0037] The flood control door 100 of the embodiment of the present invention is in an open mode before the flood breaks out, so that water can flow through. When the flood breaks out suddenly, the water level rises to a preset water level, and the water level monitoring device 4 transmits the monitored water level signal to the controller 5. The controller 5 controls the driving device 3 to start according to the received water level signal, and uses the driving device 3 to switch the door body 2 to the closed mode, thereby playing a flood control role.

[0038] Compared with the flood control door 100 in the related art that needs to be opened and closed manually, the flood control door 100 in the embodiment of the present invention can realize the automatic closing of the door body 2, greatly improving the response speed of the flood control door 100, avoiding the situation where it cannot be closed in time due to sudden floods, thereby ensuring the safety of people's lives and property and the stable operation of water conservancy facilities.

[0039] In some embodiments, the wall 1 has a receiving cavity 11 and a door slot 12 . When the door 2 is in an open mode, the door 2 is arranged in the receiving cavity 11 . When the door 2 is in a closed mode, the door 2 blocks the door slot 12 .

[0040] Specifically, if Figure 1 As shown, the wall 1 is fixed to the ground and is used to provide support for the door body 2; the accommodating cavity 11 and the door groove 12 are arranged along the left and right directions of the wall 1, and the accommodating cavity 11 has an opening arranged upward so that the door body 2 can be installed in the accommodating cavity 11. The accommodating cavity 11 also has an opening arranged toward the door groove 12, so that the accommodating cavity 11 and the door groove 12 are connected to each other, and the door body 2 can slide between the accommodating cavity 11 and the door groove 12 to switch the mode of the door body 2.

[0041] When no flood occurs, the door body 2 is in the open mode, the door body 2 is located in the accommodating cavity 11, and the water flows through the wall 1 through the door groove 12; when the water level reaches the preset water level, the door body 2 moves toward the door groove 12 and completely blocks the door groove 12, and the door body 2 switches to the closed mode, thereby achieving a flood prevention effect.

[0042] In addition, when the door body 2 is in the open mode, it can be hidden inside the wall 1 and fit into the cavity wall of the accommodating cavity 11, which can reduce the external space occupied by the door body 2.

[0043] In some embodiments, the driving device 3 includes a power piece and a screw 32. The screw 32 is rotatably connected to the wall 1. The screw 32 passes through the door body 2 and is threadedly engaged with the door body 2. The power piece is used to drive the screw 32 to rotate.

[0044] The power member drives the screw rod 32 to rotate, and the screw rod 32 cooperates with the thread of the door body 2, so that the door body 2 slides relative to the wall 1, thereby enabling the door body 2 to switch between the closed mode and the open mode.

[0045] Optionally, the power component is a servo motor 31 , and the servo motor 31 is electrically connected to the controller 5 .

[0046] In some embodiments, the driving device 3 also includes a transmission shaft 33 and a transmission assembly 34, the transmission shaft 33 is rotatably connected to the wall 1; the transmission assembly 34 includes a first bevel gear 341 and a second bevel gear 342 that are meshed with each other, the first bevel gear 341 is connected to the transmission shaft 33, and the second bevel gear 342 is connected to the screw 32.

[0047] The transmission direction can be changed by the engagement of the first bevel gear 341 and the second bevel gear 342 , which is more conducive to the reasonable distribution of the installation positions of the screw rod 32 and the power component.

[0048] In some embodiments, there are multiple screw rods 32 , and the transmission components 34 correspond one to one with the screw rods 32 .

[0049] By providing multiple screws 32, multiple screws 32 provide power for the movement of the door body 2 at the same time, which can reduce the risk of damage to a single screw 32 due to excessive force and improve the stability of the door body 2 in the open state, closed state and during the movement of the door body 2.

[0050] Specifically, if Figure 3 and Figure 4As shown, the screw 32 extends in the left and right directions of the wall 1, and the end of the screw 32 away from the door slot 12 passes through the cavity wall of the accommodating cavity 11. A bearing 321 is mounted on the screw 32, and the screw 32 is rotatably connected to the wall 1 through the bearing 321. The bearing 321 can provide support for the screw 32, improve the stability of the rotation of the screw 32, and at the same time reduce the friction between the screw 32 and the wall 1, reduce energy loss, and enable the door body 2 to slide smoothly, thereby extending the service life of components such as the screw 32 and the wall 1, reducing the maintenance frequency, and improving the operational reliability and economy of the flood control door 100.

[0051] The screw rod 32 is passed through the door body 2 and is threadedly engaged with the door body 2 . The door body 2 can be driven to slide along the left and right directions of the wall 1 by rotating the screw rod 32 , thereby switching between the open mode and the closed mode.

[0052] Wall 1 has a mounting slot 13, located on the side of accommodating chamber 11 away from door slot 12. A transmission assembly 34 is disposed within mounting slot 13. A drive shaft 33 extends vertically along wall 1, with both ends rotatably connected to the walls of mounting slot 13. A first bevel gear 341 fits over and rotates synchronously with drive shaft 33. One end of a screw rod 32 extends into mounting slot 13, and a second bevel gear 342 fits over and rotates synchronously with screw rod 32. A servo motor 31 is fixedly connected to the upper side of wall 1 via bolts. The output end of servo motor 31 extends downward and is connected to the upper end of drive shaft 33.

[0053] There are two screws 32 , which are spaced apart in the vertical direction. Each screw 32 corresponds to a transmission assembly 34 . The first bevel gears 341 of the two transmission assemblies 34 are both mounted on the transmission shaft 33 and rotate synchronously with the transmission shaft 33 .

[0054] Thus, the servo motor 31 can drive the transmission shaft 33 to rotate, and then the transmission assembly 34 can drive the two screws 32 to rotate simultaneously, so as to control the door body 2 to slide stably.

[0055] Alternatively, as Figure 1 As shown, a protective cover 6 is provided on the upper side of the wall 1 , and the protective cover 6 covers the upward opening of the accommodating cavity 11 and the servo motor 31 .

[0056] Thus, the protective cover 6 can protect precision components such as the servo motor 31, while preventing external dust, debris, etc. from entering the accommodating chamber 11, thereby ensuring the normal operation of the door body 2 and extending the service life of the door body 2. In addition, from the overall appearance, the protective cover 6 covers the upper side of the wall body 1 and matches the length of the wall body 1 (the length direction of the wall body 1 is consistent with the left-right direction), which can improve the overall structural integrity, neatness and aesthetics of the flood control door 100.

[0057] Specifically, the lower side of the protective cover 6 fits against the upper side of the wall 1 and is fixedly connected to the wall 1 by multiple bolts, which can ensure the stability of the connection between the protective cover 6 and the wall 1; when the flood control door 100 is faced with external forces such as flood impact, the stable connection between the protective cover 6 and the wall 1 can prevent the protective cover 6 from shifting or falling off, thereby ensuring the protective effect of the protective cover 6 on the internal structure; at the same time, the bolt connection method makes the installation and disassembly of the protective cover 6 more convenient, and is more conducive to the inspection and maintenance of components such as the door body 2, servo motor 31, and transmission assembly 34.

[0058] In some embodiments, the wall 1 also includes a limiting groove 14, which is connected to the door groove 12 and arranged opposite to the accommodating cavity 11. The door body 2 is connected to a first sealing part, and the groove wall of the limiting groove 14 is connected to a second sealing part. When the door body 2 is in the closed mode, the first sealing part and the second sealing part are sealed together.

[0059] Through the sealing cooperation between the first sealing part and the second sealing part, the sealing performance of the door body 2 when in the closed mode can be improved, preventing floods from seeping in from the connection gap between the door body 2 and the wall 1, and improving the overall waterproof performance of the flood control door 100, thereby effectively blocking floods and achieving flood control effects.

[0060] Specifically, if Figure 4 and Figure 5 As shown, the limiting groove 14 and the accommodating cavity 11 are arranged on both sides of the door groove 12. When the door body 2 is in the closed mode, the two sides of the door body 2 arranged relatively along the left and right directions are respectively located in the accommodating cavity 11 and the limiting groove 14, which can ensure that the door groove 12 is completely blocked.

[0061] The first sealing part is a sealing gasket 21 made of rubber. The projection of the sealing gasket 21 on the door body 2 is U-shaped, and the opening of the U is facing upward. The sealing gasket 21 is fixedly connected to the door body 2 by bonding, and the area of the door surface of the door body 2 not covered by the sealing gasket 21 forms an impact zone 22; when the door body 2 is in closed mode, the impact of the flood on the door body 2 is mainly concentrated in the impact zone 22, which can prevent the flood from impacting the sealing gasket 21 and causing damage to the sealing gasket 21, thereby ensuring the normal use of the sealing gasket 21.

[0062] The second sealing part has a sealing protrusion 15, and the number of the sealing protrusions 15 is two. The two sealing protrusions 15 are arranged opposite to each other along the thickness direction of the wall 1, and are fixedly connected to the two groove walls of the limiting groove 14 respectively; when the door body 2 is in the closed mode, the two sealing protrusions 15 are arranged opposite to each other on both sides of the door body 2 along the thickness direction of the door body 2, and the two sealing protrusions 15 respectively squeeze the two sealing gaskets 21, thereby improving the sealing of the door body 2 in the closed mode.

[0063] In addition, the provision of the sealing gasket 21 can also reduce the noise and vibration generated by the friction of the door body 2 during the sliding process, and reduce the risk of damage to internal components due to vibration.

[0064] In some embodiments, the wall 1 has a sliding groove 16 , and the door body 2 is rotatably connected to a pulley 23 , and the pulley 23 stops at the groove wall of the sliding groove 16 .

[0065] Specifically, if Figure 3 As shown, the slide groove 16 is arranged on the lower cavity wall of the accommodating cavity 11 and the lower groove wall of the door groove 12; multiple pulleys 23 are evenly distributed along the length direction of the slide groove 16 and connected to the lower side of the door body 2, and the pulley 23 stops at the bottom wall of the slide groove 16. In other words, multiple pulleys 23 can provide support for the door body 2, thereby improving the stability and smoothness of the door body 2 during movement.

[0066] In some embodiments, the water level monitoring device 4 includes a slide 41 and a water level sensor 42, the water level sensor 42 is connected to the slide 41, the door body 2 has a storage cavity 24, and the slide 41 is slidably disposed in the storage cavity 24 so that the water level sensor 42 can switch between a monitoring mode extending from the storage cavity 24 and a storage mode stored in the storage cavity 24.

[0067] The water level sensor 42 is electrically connected to the controller 5. Before the flood breaks out, the water level sensor 42 is in monitoring mode. The water level sensor 42 is located outside the storage chamber 24, and can monitor the water level in real time and transmit the water level signal to the controller 5; when the flood breaks out, the water level rises and reaches the preset water level. The controller 5 controls the servo motor 31 to start based on the received water level signal, and then controls the door body 2 to switch to the closed mode, thereby realizing automatic flood prevention.

[0068] Optionally, there are two water level monitoring devices 4 , and the two water level monitoring devices 4 are arranged at intervals in the upper and lower directions.

[0069] In this way, the accuracy of water level monitoring can be improved and the probability of water level misjudgment can be reduced.

[0070] In some embodiments, the flood control door 100 further includes a telescopic member, which is electrically connected to the controller 5 . The telescopic member has a first section and a second section that are relatively telescopic. The first section is connected to the wall 1 , and the second section is connected to the slide 41 .

[0071] Optionally, the telescopic member is an electric push rod 7, and the cylinder and rod body of the electric push rod 7 respectively form the above-mentioned first section and second section.

[0072] Specifically, if Figure 5 and Figure 6As shown, the water level monitoring device 4 is arranged on the side of the door body 2 facing the door groove 12, the storage cavity 24 has a storage opening 241 arranged toward the door groove 12, and the slide 41 can extend out of the storage cavity 24 through the storage opening 241; the slide 41 is frame-shaped, and the water level sensor 42 is arranged inside the frame of the slide 41 and is fixedly connected to the slide 41; the cylinder of the electric push rod 7 is fixedly connected to the cavity wall of the storage cavity 24, and the rod body of the electric push rod 7 is fixedly connected to the slide 41.

[0073] When a flood breaks out, the water level rises and reaches the preset water level. The controller 5 controls the servo motor 31 to start and the electric push rod 7 to retract based on the received water level signal, so that the door body 2 slides toward the door groove 12. At the same time, the fixing frame and the water level sensor 42 slide into the storage cavity 24, and the water level sensor 42 switches to the storage mode so that the door body 2 can be closed normally; then the door body 2 switches to the closed state to achieve automatic flood prevention.

[0074] In some embodiments, the flood control door 100 also includes an alarm module, which is electrically connected to the controller 5; and / or the flood control door 100 also includes a monitoring module, which is electrically connected to the controller 5; and / or the flood control door 100 also includes a Bluetooth module 83, which is electrically connected to the controller 5.

[0075] Optionally, the alarm module is a buzzer alarm 81 , and the buzzer alarm 81 is electrically connected to the controller 5 .

[0076] When the water level rises to a preset level or other electrical components in the flood control door 100 malfunction, the controller 5 controls the buzzer alarm 81 to sound an alarm, promptly reminding people around to pay attention to the status of the flood control door 100, and reminding them to take corresponding flood control measures or conduct safe evacuation when a flood breaks out, thereby improving the safety of the flood control door 100 and avoiding casualties and property losses caused by sudden floods.

[0077] Optionally, the monitoring module is a camera 82 , and the camera 82 is electrically connected to the controller 5 .

[0078] The camera 82 can monitor the flood situation around the flood control gate 100, providing an intuitive visual basis for flood control decisions.

[0079] In addition, the Bluetooth module 83 is electrically connected to the controller 5, and the Bluetooth module 83 can connect, communicate and control other devices. The back-end staff can use the Bluetooth module 83 to remotely control the operation of the servo motor 31 through the information monitored by the camera 82; when the water level sensor 42 fails, the staff can remotely operate to switch the door body 2 to the closed mode in time.

[0080] like Figure 5As shown, the controller 5 is arranged on the side of the wall 1 and is fixedly connected to the wall 1 , the Bluetooth module 83 is integrated into the controller 5 , and the camera 82 is arranged on one side of the controller 5 .

[0081] like Figure 1 and Figure 2 As shown, the flood control door 100 also includes a protective cover 9 made of a transparent material. The protective cover 9 is provided to cover the controller 5, the Bluetooth module 83, and the camera 82. The protective cover 9 can block external factors such as dust and water vapor, ensuring the normal operation of the controller 5, the camera 82, and other electrical components. In addition, the transparent protective cover 9 can also be used by staff to observe the status of the indicator lights and other status displays on the controller 5, facilitating a preliminary understanding of the working status of the controller 5 without opening the protective cover 9. It also facilitates some visual operations in emergency situations, such as checking the connection status of the Bluetooth module 83.

[0082] The protective cover 9 is fixedly connected to the wall 1 by bolts. When the flood control door 100 is subjected to vibration or other external forces, the bolt connection method can prevent the protective cover 9 from loosening or falling, thereby continuously protecting electrical components such as the controller 5; at the same time, the stable connection between the protective cover 9 and the wall 1 can also improve the sealing performance between the protective cover 9 and the wall 1, preventing water vapor and the like from entering the interior of the protective cover 9, and further improving the protection effect of electrical components such as the controller 5.

[0083] like Figure 1 and Figure 2 As shown, the buzzer alarm 81 is arranged on the upper side of the protective cover 9 and is fixedly connected to the protective cover 9.

[0084] The flood control door 100 of the embodiment of the present invention, when a flood breaks out and the water level rises to a preset water level, the controller 5 sends a control signal to the servo motor 31, the electric push rod 7 and the buzzer alarm 81 based on the received water level signal, controls the rod body of the electric push rod 7 to retract, so that the water level sensor 42 switches to the storage mode, controls the buzzer alarm 81 to sound an alarm, reminds the surrounding people to take emergency shelter and take flood control measures in time, controls the servo motor 31 to start, and then controls the screw 32 to rotate, so that the door body 2 switches to the closed mode, thereby playing a flood control role.

[0085] The flood control door 100 of the embodiment of the present invention coordinates the various components through the controller 5, making the operation of the door body 2 more accurate and efficient, thereby improving the reliability and automation level of the operation of the flood control door 100, effectively reducing the threat posed by floods to the safety of people's lives and property and the stable operation of water conservancy facilities, and timely blocking floods to reduce the huge losses that may be caused by the influx of floods.
