[0048] The technical solution of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0049] The present application provides an automatic flood control device that can automatically raise a flood control baffle according to the amount of rainwater to achieve the purpose of flood control. In this regard, the automatic flood control device of the present application can be divided into two states. The first water collection state represents the situation where the current amount of water is small and there is no need to raise the baffle for flood control yet, while the second water collection state represents the situation where the current amount of water is large and it is necessary to raise the baffle for flood control to block the spread of the water.

[0050] Based on this, as Figure 1-7 shown, the automatic flood control device provided by the present application includes: a water collection assembly 100, a transmission assembly 200, and a baffle assembly 300. The water collection assembly 100 is used to detect the amount of rainwater, and its position can be set at the low point of water collection around the flood control site and can be connected to the drainage system to collect rainwater. The transmission assembly 200 is used to control the operation of the baffle assembly 300 according to the amount of water in the water collection assembly 100.

[0051] Among them, the water collection component 100 includes: a water tank 11, which can be connected to the drainage system in the site and is used to collect rainwater in the site where it is located.

[0052] The transmission component 200 includes: a lever 21 and a hook 22. The two ends of the lever 21 are respectively a first end and a second end. The first end of the lever 21 is connected to the bottom of the water tank 11, and the second end is connected to the hook 22. In the first water collection state, the amount of water in the water tank 11 is small. Due to the small gravity of the water body, the position of the bottom of the water tank 11 is not lower than a preset height, and the position of the first end of the lever 21 connected to the bottom of the water tank 11 is also not lower than the preset height. In the second water collection state, the amount of water in the water tank 11 has reached the state where flood control is required. Due to the large gravity of the water, the position of the bottom of the water tank 11 will be lower than the preset height, and the position of the first end of the lever 21 connected to the bottom of the water tank 11 is also lower than the preset height. It can be understood that the preset height here can be set according to flood control needs.

[0053] The baffle component 300 includes: a baffle 31 and a first spring 32. One end of the first spring 32 is fixed at a first position, and the other end is connected to the bottom of the baffle 31, so that the first spring 32 is in a stretched state in the first water collection state. It can be understood that the height at the first position here needs to make the first spring 32 in a stretched state in the first water collection state. And the bottom of the baffle 31 is also connected to the hook 22. In the first water collection state, the position of the first end of the lever 21 is not lower than the preset height, and the position of the second end of the lever 21 remains unchanged, so that the bottom of the baffle 31 remains hooked to the hook 22, and the first spring 32 remains in a stretched state, and the baffle 31 also remains in the "retracted" state. In the second water collection state, the first end of the lever 21 being lower than the preset height causes the second end of the lever 21 to displace, the bottom of the baffle 31 disengages from the hook 22, the first spring 32 contracts, driving the baffle 31 to rise under the action of the first spring 32. After rising, the baffle 31 can block the spread of the water potential in its area.

[0054] Based on the above structure, the present application can achieve that when the water volume exceeds a certain threshold, the flood control baffle automatically rises without manual monitoring and operation, thereby achieving an automatic response to disasters and reducing the impact of disasters.

[0055] In view of the situation that foreign objects may fall into the water tank 11 and affect the weight of the water tank 11, in some preferred embodiments, the water collection component 100 further includes: a dust cover 12, and the dust cover 12 is arranged on the top of the water tank 11, which can, to a certain extent, prevent foreign objects from falling into the water tank 11.

[0056] In some more preferred embodiments, the automatic flood control device provided by the present application further includes: a foreign object compensation component 400, which is disposed at the bottom of the water collection component 100 and includes: a second magnet 41. Correspondingly, a first magnet 13 is also disposed at the bottom of the water collection component 100. The two first magnets 13, which are also disposed at the bottom of the water tank 11, repel the second magnet 41 to generate a reaction force against the gravity of the water tank 11. That is, the second magnet 41 and the first magnet 13 form a repulsive force to offset the gravity influence of foreign objects in the water tank 11. It can be understood that different magnet pairs have different magnetic permeabilities, and users can select magnets with appropriate magnetic permeabilities according to needs to adapt to different degrees of foreign object intrusion.

[0057] Preferably, the foreign object compensation component 400 includes: a plurality of second magnets 41 and a magnet support 42. The plurality of second magnets 41 are evenly distributed around the magnet support 42 to form a more stable acting force. For example, there may be four second magnets 41, and the magnet support 42 is a cross-shaped support. The four second magnets 41 are respectively fixed at the four vertices of the cross-shaped support.

[0058] Regarding the specific structure of the water collection component 100, in a specific embodiment, the water collection component 100 can be integrally disposed in a site sump, which is located at the low water collection point around the site to be flood-controlled and is connected to the drainage system. The water collection component 100 further includes: a water tank guide rail 14 and a second spring (not shown in the figure). Among them, the water tank guide rail 14 is disposed in the side wall of the site sump and is used to limit the movement of the water tank 11, so that the water tank 11 moves along the direction of the water tank guide rail 14. One end of the second spring is fixed to the bottom of the site sump, and the other end is connected to the bottom of the water tank 11. The second spring is used to form a supporting force on the water tank 11. As the water volume in the water tank 11 increases, the second spring will gradually compress and deform. Preferably, the water collection component 100 may further include: a water seal structure 15, which is disposed at the opening of the water tank 11 to reduce water loss.

[0059] Regarding the connection method between the water collection component 100 and the transmission component 200, in a specific embodiment, both ends of the lever 21, that is, the first end and the second end of the lever 21, can be set as two independently movable components. However, when the first end of the lever 21 is not lower than the preset height, the position of the second end of the lever 21 remains unchanged. At the same time, once the first end of the lever 21 is lower than the preset height, the position of the second end of the lever 21 will change accordingly. In this way, the first end of the lever 21 can be directly connected to the bottom of the water tank 11. As the water volume in the water tank 11 increases, the bottom position of the water tank 11 will become lower and lower. When the water volume in the water tank 11 exceeds a certain threshold, the bottom position of the water tank 11 and the first end of the lever 21 connected to the bottom of the water tank 11 will be lower than the preset height. For example, a bearing is provided at the center of the lever 21. As long as the height of the first end of the lever 21 is not lower than the preset height, this bearing can control the position of the second end of the lever 21 to remain stationary. Once the height of the first end of the lever 21 drops below the preset height, this bearing will control the second end of the lever 21 to lift, causing the hook 22 at the second end of the lever 21 to disengage from the baffle 31.

[0060] In some other more optimal embodiments, the lever 21 further includes: a pulley 211, a force transmission link 212, and a sesame chain 213. Among them, the first end of the force transmission link 212 is equivalent to the first end of the lever 21 and is connected to the second spring provided at the bottom of the water tank 11 through the pulley 211. The specific connection position can correspond to the above-mentioned preset height at the bottom of the water tank 11. The second end of the force transmission link 212 is equivalent to the second end of the lever 21 and is connected to the hook 22 through the sesame chain 213. In this connection method, the first end of the force transmission link 212 is not directly connected to the bottom of the water tank 11, but is connected to the second spring provided at the bottom of the water tank 11. Due to the gravitational force of the water body in the water tank 11, the second spring will have an increasing deformation as the water depth increases. When the deformation exceeds a certain threshold, the state of the force transmission link 212 changes. The first end of the force transmission link 212 undergoes displacement due to the deformation of the second spring, thereby driving the second end of the force transmission link 212 to undergo displacement. The sesame chain 214 at the second end of the force transmission link 212 serves as a force transmission mechanism, and transmits the power generated by this displacement from its driving wheel to its driven wheel. When the driven wheel rotates, it drives the bottom of the hook 22 to undergo displacement, so that the hook of the hook 22 is disengaged from the bottom of the baffle 31.

[0061] Regarding the specific structure of the baffle component 300, in a specific embodiment, the baffle component 300 is arranged in a baffle pre-buried pit, and the position of this baffle pre-buried pit is arranged in the area where flood control is required. This baffle pre-buried pit is divided into a first accommodation space and a second accommodation space located below the first accommodation space. The first accommodation space is used to limit the movement of the baffle 31, and the second accommodation space is used to transmit force between the baffle 31 and the transmission component 200.

[0062] Among them, the baffle assembly 300 further includes: a baffle guide rail 33, which is disposed on the side wall of the first accommodating space to ensure that the baffle 31 does not sway left and right after rising. And the first spring 32 for transmitting force is disposed in the second accommodating space, with one end fixed to the top of the second accommodating space and the other end connected to the bottom of the baffle 31. It can be understood that the top of the second accommodating space here is the first position described above.

[0063] In order to prevent the baffle 31 from rising too fast during the rising process and thus having an adverse effect, the baffle assembly 300 further includes: a damper 34. At the same time, both sides of the side wall of the second accommodating space include: side wall saw teeth 35. The damper 34 is disposed at the bottom of the baffle 31, and its two ends can be lapped with the side wall saw teeth 35 on both sides of the second accommodating space side wall, and can slowly move upward between the side wall saw teeth 35 on both sides against the resistance of the saw teeth under the action of the first spring 32. For example, the damper 34 can be set as a horizontal plate, and the shape of each saw tooth in the side wall saw teeth 35 is set as a right triangle, and the included angle between its hypotenuse and the damper 34 is 45°. During the upward movement of the damper 34, its two ends can overcome the resistance brought by the saw tooth included angle and slowly rise, and when the damper 34 stops moving upward, its two ends can be lapped on the right-angled sides of the saw teeth, and the damper 34 is kept from falling under the horizontal supporting force, thereby restricting the falling of the baffle 31.

[0064] Under the above structure, in order to facilitate the repeated use of the device, the present application also designs a mechanism that can reset the baffle from the rising state. That is, the automatic flood control device provided by the present application further includes: a reset assembly 500, and the reset assembly 500 includes: a handle 51, a spring bracket 52 and a third spring 53.

[0065] Among them, the third spring 53 is horizontally disposed between the side wall of the second accommodating space and the side wall of the side wall saw teeth 35, with one end fixed in the side wall of the second accommodating space and the other end connected to the side wall of the side wall saw teeth 35. The spring bracket 52 includes: an X-shaped movable frame 521 and a handle connecting rod 522. The two ends of the handle connecting rod 522 are fixedly connected to the two top ends of the X-shaped movable frame 521, and the four ends of the X-shaped movable frame 521 are respectively fixed in the side wall saw teeth 35 on both sides. And, a movable shaft 523 is provided in the middle of the handle connecting rod 522. By moving the movable shaft 523, the handle connecting rod 522 can be made to present a downwardly concave V shape or a straight line shape, and the X-shaped movable frame 521 can be opened or contracted at its upper and lower ends with its middle intersection point as the central axis 524, thereby driving the side wall saw teeth 35 on both sides to open or contract horizontally.

[0066] Preferably, the baffle assembly 300 further includes: a steel side wall 36 and a baffle dust cover, wherein the steel side wall 36 is disposed between the side wall serrations 35 and the third spring 53 to ensure smooth movement of the side wall serrations 35. The baffle dust cover can prevent foreign matter from being introduced into the baffle pre-buried pit.

[0067] At the same time, the bottom of the handle 51 is connected to the movable shaft 523. When the handle 51 is pulled, the movable shaft 523 in the handle connecting rod 522 moves upward, driving the handle connecting rod 522 to open, thereby spreading the top and bottom ends of the X-shaped movable frame 521. Under the force of the X-shaped movable frame 521, the third spring 53 is compressed, increasing the distance between the side wall serrations 35 on both sides, causing the damper 34 to fall between the side wall serrations 35 on both sides, thereby driving the baffle 31 to fall and return to its original position. It is understood that the bottom of the baffle 31 can be provided with a component that cooperates with the hook 22. When the baffle 31 returns to its original position and the amount of water in the sink 11 causes the first end of the lever 21 to be no lower than a preset height, the hook 22 can automatically reconnect with the component at the bottom of the baffle 31, facilitating the next use.

[0071] The automatic flood control device provided by the present application includes a water collection assembly, a transmission assembly, and a baffle assembly. In a first water collection state where flood control is not required, the water volume in the water tank of the water collection assembly is low, and the first end of the lever in the transmission assembly is not lower than a preset height. In a second water collection state where flood control is required, the water volume in the water tank of the water collection assembly is high, driving the first end of the lever in the transmission assembly below the preset height, causing the second end of the lever to displace and driving the bottom of the baffle in the baffle assembly to disengage from the hook, thereby causing the baffle to automatically rise under the contraction force of the first spring. The present application can automatically raise the flood control baffle when the water volume exceeds a certain threshold, without the need for manual monitoring and operation, thereby achieving automatic response to disasters and reducing the impact of disasters.
