Description

Technical Field

[0001] This utility model belongs to the field of flood prevention equipment technology, specifically relating to an intelligent drop-down flood prevention device. Background Technology

[0002] Floodproof doors are commonly used at the entrances of underground passages where flooding and waterlogging are severe. They are suitable for subway station entrances and exits, garage entrances and exits, pedestrian passages, and other locations. During heavy rain or torrential rain, they can block the water that cannot be drained away on the ground in time, buying time for the evacuation of people in underground buildings, and also preventing damage to equipment and materials in underground buildings.

[0003] At present, the entrances and exits of subway stations and other buildings mainly rely on temporary sandbags to block rainwater. The sandbags are usually moved and stacked manually, which takes a lot of time. In addition, there are still many leakage points between the sandbags after they are stacked, so the water blocking efficiency is not convenient and efficient enough. Summary of the Invention

[0004] This invention provides an intelligent drop-down flood prevention device to at least solve some of the aforementioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A smart drop-down flood prevention device includes a mounting frame, a water-blocking mechanism slidably mounted on the mounting frame, two sets of drive mechanisms mounted on the mounting frame for driving the water-blocking mechanism to slide, two liquid level sensors mounted on both sides of the outside of the mounting frame for detecting the ground water level, and a control mechanism mounted on the mounting frame and connected to the drive mechanisms and liquid level sensors respectively.

[0006] Furthermore, the water-blocking mechanism includes sliding frames respectively mirror-symmetrically disposed on the inner walls of both sides of the mounting frame, a water-blocking plate slidably disposed on the sliding frames and connected to the drive mechanism, and a limiting mechanism movably disposed within the two sliding frames and respectively connected to both sides of the water-blocking plate.

[0007] Furthermore, the sliding frame is provided with a limiting groove, and the limiting mechanism includes a mounting shaft mirror-symmetrically disposed on the side wall of the baffle plate, and a roller rotatably disposed on the mounting shaft and located in the limiting groove.

[0008] Furthermore, the baffle plate is provided with a U-shaped sealing strip, which surrounds the bottom and side walls of the baffle plate.

[0009] The mounting bracket is equipped with a drive bracket, and the drive bracket is equipped with a sprocket clearance groove. The drive mechanism includes a drive motor on the drive bracket, a drive sprocket on the output end of the drive motor and located in the sprocket clearance groove, a sprocket mounting shaft in the sprocket clearance groove, a driven sprocket on the rotating sprocket mounting shaft, and a chain between the drive sprocket and the driven sprocket and connected to the water blocking mechanism.

[0010] The chain is provided with two mounting mechanisms for fixing the water-blocking mechanism. The mounting mechanism includes mounting seats that are mirror-symmetrically arranged on both sides of the chain and connected to the chain pin. The mounting seats pass through the sprocket clearance groove and are connected to the water-blocking mechanism.

[0011] Furthermore, the control mechanism includes a control box mounted on a mounting bracket, control buttons located inside the control box, and a microcontroller located inside the control box and connected to the control buttons, the drive mechanism, and the liquid level sensor, respectively.

[0012] Furthermore, the mounting bracket includes a base, two uprights mirror-symmetrically disposed on the base, rain shields disposed on the top of the two uprights, and a water seepage mechanism disposed on the base.

[0013] Furthermore, the seepage mechanism includes a waterproof groove on the base, a drain hole on the base and connected to the waterproof groove, and a baffle on the base and adapted to the waterproof groove, with seepage holes evenly distributed on the baffle.

[0014] Furthermore, it also includes an audible and visual alarm mounted on a mounting bracket and connected to the control mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model has a simple structure, a scientific and reasonable design, and is easy to use. The water-blocking mechanism of this utility model is housed on the top of the mounting frame under the action of the driving mechanism, so that the water-blocking mechanism does not occupy the passage space. In use, the liquid level sensor can detect the ground water level on both sides of the mounting frame in real time and transmit the detection result to the control mechanism. When the detection result of the liquid level sensor is higher than the preset value, the control mechanism controls two sets of control mechanisms to operate simultaneously. The two sets of control mechanisms simultaneously drive the water-blocking mechanism to slide on the mounting frame, so that the water-blocking mechanism contacts the mounting frame, thereby blocking the rainwater.

[0034] In this embodiment 2, the sliding frame 3 is mirror-symmetrically arranged on the inner walls of both sides of the mounting frame 1. The sliding frame 3 can guide the sliding direction of the baffle plate 4, and the limiting mechanism can limit the baffle plate 4 so that the baffle plate 4 can always move up and down along the sliding frame 3, thereby facilitating the driving mechanism to drive the baffle plate 4 to block rainwater.

[0046] The drive motor 10 is mounted on the top of the mounting bracket 1, and the output end of the drive motor 10 passes through the drive bracket 27 and is located in the sprocket clearance groove 9. The drive motor 10 is mounted on the mounting bracket 1. When in use, the drive motor 10 is started, and the drive motor 10 drives the drive sprocket 11 to rotate, thereby causing the chain 13 to rotate between the drive sprocket 11 and the driven sprocket 12, so that the chain 13 drives the baffle plate 4 to rise or fall.

[0048] The mounting bracket 1 is provided with a drive bracket 27, and a sprocket clearance groove 9 is provided on the drive bracket 27. The drive mechanism includes a drive motor 10 provided on the drive bracket 27, a drive sprocket 11 provided on the output end of the drive motor 10 and located in the sprocket clearance groove 9, a sprocket mounting shaft 26 provided in the sprocket clearance groove 9, a driven sprocket 12 that rotates the sprocket mounting shaft 26, and a chain 13 provided between the drive sprocket 11 and the driven sprocket 12 and connected to the water blocking mechanism.

The mounting mechanism includes mounting seats 14 that are mirror-symmetrically arranged on both sides of the chain 13 and connected to the chain pin. The mounting seats 14 pass through the sprocket clearance groove 9 and are connected to the water-blocking mechanism.

[0050] In this embodiment 6, there are two installation mechanisms. Specifically, the installation mechanism includes mounting seats 14 that are mirror-symmetrically arranged on both sides of the chain 13 and connected to the chain pin.

The microcontroller 17 is connected to the control button 16, the drive motor 10, and the liquid level sensor 2. In use, when the detection result of the liquid level sensor 2 is greater than the preset value, the microcontroller 17 controls the drive motor 10 to run, so that the baffle 4 can block rainwater. At the same time, the control button 16 controls the drive motor 10 to run through the microcontroller 17, thereby realizing the manual control of the drive motor 10, which facilitates the control of the raising and lowering of the baffle 4. Example

[0055] like Figure 1-9 As shown, the present invention provides an intelligent drooping flood prevention device, including a mounting frame 1, a water-blocking mechanism slidably mounted on the mounting frame 1, two sets of driving mechanisms mounted on the mounting frame 1 for driving the water-blocking mechanism to slide, two liquid level sensors 2 mounted on both sides of the outside of the mounting frame 1 for detecting the ground water level, and a control mechanism mounted on the mounting frame 1 and connected to the driving mechanisms and the liquid level sensors 2 respectively.

The base 18 is provided with a water seepage mechanism, which can drain the rainwater from the base 18 to prevent rainwater from entering the room. Example

[0058] like Figure 1-9 As shown, the present invention provides an intelligent drooping flood prevention device, including a mounting frame 1, a water-blocking mechanism slidably mounted on the mounting frame 1, two sets of driving mechanisms mounted on the mounting frame 1 for driving the water-blocking mechanism to slide, two liquid level sensors 2 mounted on both sides of the outside of the mounting frame 1 for detecting the ground water level, and a control mechanism mounted on the mounting frame 1 and connected to the driving mechanisms and the liquid level sensors 2 respectively.

[0059] The mounting bracket 1 includes a base 18, two uprights 19 mirror-symmetrically disposed on the base 18, a rain shield 20 disposed on the top of the two uprights 19, and a water seepage mechanism disposed on the base 18.

The waterproof groove 21 can collect rainwater on the base 18 and discharge the rainwater collected in the waterproof groove 21 through the drainage hole 22. At the same time, a baffle 23 is set on the base 18 and located on top of the waterproof groove 21.

[0062] Example 10.

[0063] like Figure 1-9 As shown, the present invention provides an intelligent drooping flood prevention device, including a mounting frame 1, a water-blocking mechanism slidably mounted on the mounting frame 1, two sets of driving mechanisms mounted on the mounting frame 1 for driving the water-blocking mechanism to slide, two liquid level sensors 2 mounted on both sides of the outside of the mounting frame 1 for detecting the ground water level, and a control mechanism mounted on the mounting frame 1 and connected to the driving mechanisms and the liquid level sensors 2 respectively.

[0064] It also includes an audible and visual alarm 25 mounted on the mounting bracket 1 and connected to the control mechanism.

[0065] In this embodiment 10, the audible and visual alarm 25 is installed on one of the columns 19. When in use, when the water baffle 4 is rising or falling, the microcontroller 17 controls the audible and visual alarm 25 to operate, thereby reminding pedestrians to pay attention and avoid the water, and improving the safety of the flood prevention device.

[0066] The microcontroller used in this invention can be an STM32F103 microcontroller.

[0067] This invention uses a drive motor 10 that is a forward and reverse rotating motor.

[0068] Working principle.

[0069] In use, the baffle plate 4 is in the normally open state, that is, the baffle plate 4 is located on top of the sliding frame 3. When the liquid level sensor 2 detects the ground water level in real time and transmits the detection result to the microcontroller 17, when the detection result of the liquid level sensor 2 is higher than the preset value, the microcontroller 17 simultaneously controls the drive motor 10 and the audible and visual alarm 25 to run. The drive motor 10 rotates forward, driving the drive sprocket 11 to rotate, thereby causing the chain 13 to rotate between the drive sprocket 11 and the driven sprocket 12, causing the chain 13 to drive the baffle plate 4 to descend, so that the bottom of the baffle plate 4 is flush with the base. The tops of the 18 plates are pressed together to block rainwater. When the detection result of the liquid level sensor 2 is lower than the preset value, the microcontroller 17 controls the drive motor 10 and the audible and visual alarm 25 to run again. The drive motor 10 reverses and drives the drive sprocket 11 to rotate, so that the chain 13 rotates between the drive sprocket 11 and the driven sprocket 12. The chain 13 drives the water baffle 4 to rise, so that the water baffle 4 separates from the base 18, so that the water baffle 4 is located on the top of the sliding frame 3, which facilitates the passage of pedestrians. This completes the raising and lowering of the water baffle 4, which facilitates the blocking of rainwater.

[0070] The liquid level sensor 2, drive motor 10, microcontroller 17 and audible and visual alarm 25 used in this utility model are existing technologies that can be directly purchased and used on the market. Therefore, the structure, principle and circuit of the liquid level sensor 2, drive motor 10, microcontroller 17 and audible and visual alarm 25 will not be described in detail here.
