[0010] In the second water collection state, the first end of the lever is lower than the preset height, and the second end of the lever is displaced, causing the bottom of the baffle to disengage from the hook, thereby causing the baffle to rise under the contraction force of the first spring.

[0011] Preferably, the water collection assembly further includes: a dust cover;

[0012] The dust cover is installed on the top of the water tank.

[0013] Preferably, the device further includes: a foreign object compensation component;

[0015] The bottom of the water collection component is also provided with a first magnet, which repels the second magnet to generate a reaction force against the gravity of the water tank.

[0016] Preferably, the foreign object compensation component includes: a plurality of second magnets and a magnet support; the plurality of second magnets are evenly distributed around the magnet support.

[0017] Preferably, the water collection component is disposed in the site water collection pit, and the water collection component further includes: a water trough guide rail;

[0018] The water trough guide rail is installed in the side wall of the site's water collection pit, allowing the water trough to move along the direction of the water trough guide rail.

[0019] Preferably, the water collection component is disposed in the site water collection pit, and the water collection component further includes: a second spring;

[0020] One end of the second spring is fixed to the bottom of the site's water collection pit, and the other end is connected to the bottom of the water trough.

[0022] The first end of the force transmission link is connected to the second spring via the pulley, and the second end is connected to the hook via the sesame chain.

[0023] Preferably, the baffle assembly is disposed in a baffle pre-embedded pit, the baffle pre-embedded pit including: a first accommodating space and a second accommodating space located below the first accommodating space;

[0024] The baffle assembly further includes a baffle guide rail, which is disposed in the side wall of the first accommodating space;

[0025] The first spring 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.

[0026] Preferably, the baffle assembly further includes: a damper; the sidewalls of the second accommodating space include: sidewall serrations;

[0027] The damper is disposed at the bottom of the baffle, and the two ends of the damper overlap with the side wall serrations of the second accommodating space and move upward between the side wall serrations on both sides.

The four ends of the X-shaped movable frame are respectively fixed in the side wall serrations on both sides.

[0031] When the handle is pulled up, the movable axis moves upward, causing the handle connecting rod to open the top and bottom ends of the X-shaped movable frame. The third spring is compressed under the force of the X-shaped movable frame, increasing the distance between the side wall serrations, causing the damper to fall out from between the side wall serrations.

[0032] The automatic flood control device provided in this application includes a water collection assembly, a transmission assembly, and a baffle assembly. In the first water collection state where flood control is not required, the water volume in the 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 the second water collection state where flood control is required, the water volume in the tank of the water collection assembly is high, causing the first end of the lever in the transmission assembly to fall below the preset height. This displacement of the second end of the lever causes 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. This application can automatically raise the flood control baffle when the water volume exceeds a certain threshold, without the need for manual monitoring and operation, thus achieving automatic disaster response and reducing the impact of disasters.

[0048] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] This application provides an automatic flood control device that can automatically raise a flood control barrier according to the amount of rainfall to achieve the purpose of flood control. The automatic flood control device of this application can be divided into two states. The first water collection state represents a situation where the current water volume is small and there is no need to raise the barrier for flood control. The second water collection state represents a situation where the current water volume is large and the barrier needs to be raised to prevent the spread of water.

[0050] Based on this, such as Figure 1-7 As shown, the automatic flood control device provided in this 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 location can be set at the lowest point of water catchment around the flood-prone area, and it can be connected to a 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] The water collection component 100 includes a water tank 11, which can be connected to the drainage system within the site to collect rainwater from the site.

[0052] The transmission assembly 200 includes a lever 21 and a hook 22. The lever 21 has a first end and a second end, respectively. 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 water volume in the water tank 11 is low. Due to the low gravity of the water, 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 water volume in the water tank 11 has reached a level requiring flood control. Due to the high gravity of the water, the bottom of the water tank 11 is 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 is understandable that the preset height can be set according to flood control needs.

[0053] The baffle assembly 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 during the first water collection state. It is understood that the height of the first position is necessary for the first spring 32 to be in a stretched state during the first water collection state. Furthermore, the bottom of the baffle 31 is also connected to a hook 22. During the first water collection state, the position of the first end of the lever 21 is not lower than a preset height, and the position of the second end of the lever 21 remains fixed, keeping the bottom of the baffle 31 connected to the hook 22, and the first spring 32 remains stretched, while the baffle 31 remains in a "retracted" state. During the second water collection state, the first end of the lever 21 is lower than the preset height, causing the second end of the lever 21 to shift. The bottom of the baffle 31 disengages from the hook 22, the first spring 32 contracts, and the baffle 31 rises under the force of the first spring 32. After rising, the baffle 31 can prevent the spread of water in its area.

[0054] Based on the above structure, this application can automatically raise the flood control barrier when the water volume exceeds a certain threshold, without the need for manual monitoring and operation, thereby realizing automatic disaster response and reducing the impact of disasters.

[0055] In view of the possibility 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 assembly 100 further includes a dust cover 12, which is disposed on the top of the water tank 11 and can prevent foreign objects from falling into the water tank 11 to a certain extent.

[0056] In some preferred embodiments, the automatic flood control device provided in this 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 mutual repulsive force to counteract the gravitational influence of foreign objects in the water tank 11. It is understood that different magnet pairs have different magnetic permeabilities, and users can select magnets with appropriate magnetic permeabilities as needed to accommodate different degrees of foreign object intrusion.

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

[0058] Regarding the specific structure of the water collection component 100, in one specific embodiment, the water collection component 100 can be entirely installed within a site drainage pit. This site drainage pit is located at the lowest point of the water flow around the flood-prone area and is connected to the drainage system. The water collection component 100 also includes: a water trough guide rail 14 and a second spring (not shown in the figure). The water trough guide rail 14 is disposed in the side wall of the site drainage pit and is used to limit the movement of the water trough 11, allowing the water trough 11 to move along the direction of the water trough guide rail 14. One end of the second spring is fixed to the bottom of the site drainage pit, and the other end is connected to the bottom of the water trough 11. The second spring provides support for the water trough 11, and as the water volume in the water trough 11 increases, the second spring gradually compresses and deforms. Preferably, the water collection component 100 may further include: a water seal structure 15, which is located at the opening of the water trough 11 to reduce water loss.

[0059] Regarding the connection method between the water collection component 100 and the transmission component 200, in one specific embodiment, the two ends of the lever 21, namely the first end and the second end of the lever 21, can be configured as two independently movable components. However, the position of the second end of the lever 21 must remain unchanged when the first end of the lever 21 is not lower than a preset height. Conversely, once the first end of the lever 21 falls below the preset height, the position of the second end of the lever 21 will change accordingly. In this method, the first end of the lever 21 can be directly connected to the bottom of the water tank 11. As the amount of water in the water tank 11 increases, the bottom position of the water tank 11 will decrease. When the amount of water 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 fall below the preset height. For example, a bearing is set in 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, the bearing can control the position of the second end of the lever 21 to remain unchanged. Once the height of the first end of the lever 21 drops to a height lower than the preset height, the bearing will control the second end of the lever 21 to lift up, so that the hook 22 of the second end of the lever 21 is disengaged from the baffle 31.

[0060] In some preferred embodiments, lever 21 further includes a pulley 211, a force-transmitting link 212, and a sesame chain 213. The first end of the force-transmitting link 212 corresponds to the first end of lever 21 and is connected to a second spring located at the bottom of the water tank 11 via pulley 211. The specific connection position corresponds to the aforementioned preset height of the bottom of the water tank 11. The second end of the force-transmitting link 212 corresponds to the second end of lever 21 and is connected to hook 22 via sesame chain 213. In this connection method, the first end of the force-transmitting link 212 is not directly connected to the bottom of the water tank 11, but rather to the second spring located at the bottom of the water tank 11. Due to the gravity of the water in the tank 11, the deformation of the second spring increases with the depth of the water. When the deformation exceeds a certain threshold, the force transmission link 212 changes state. The first end of the force transmission link 212 is displaced due to the deformation of the second spring, which in turn causes the second end of the force transmission link 212 to be displaced. The sesame chain 214 at the second end of the force transmission link 212 acts as a force transmission mechanism, transmitting the power generated by the displacement to its driven wheel through its driving wheel. When the driven wheel rotates, it causes the bottom of the hook 22 to be displaced, thereby causing the hook of the hook 22 to disengage from the bottom of the baffle 31.

[0061] Regarding the specific structure of the baffle assembly 300, in one specific embodiment, the baffle assembly 300 is disposed in a baffle pre-embedded pit, which is located in the area where flood control is required. The baffle pre-embedded pit is divided into a first accommodating space and a second accommodating space located below the first accommodating space. The first accommodating space is used to limit the movement of the baffle 31, and the second accommodating space is used to transmit force between the baffle 31 and the transmission assembly 200.

[0062] The baffle assembly 300 further includes a baffle guide rail 33, which is disposed in the side wall of the first accommodating space to ensure that the baffle 31 does not sway left and right after being raised. A 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 is the first position mentioned above.

[0063] To prevent the baffle 31 from rising too quickly and causing adverse effects, the baffle assembly 300 further includes a damper 34, and the side walls of the second accommodating space include side wall serrations 35. The damper 34 is located at the bottom of the baffle 31, and its two ends can engage with the side wall serrations 35 of the second accommodating space. Under the force of the first spring 32, it can slowly move upwards between the side wall serrations 35, overcoming the resistance of the serrations. For example, the damper 34 can be configured as a horizontal plate, with each serration in the side wall serrations 35 shaped as a right-angled triangle, the angle between its hypotenuse and the damper 34 being 45°. During its upward movement, the damper 34 can slowly rise by overcoming the resistance from the angle of the serrations, and when the damper 34 stops moving upwards, its two ends can engage with the right-angled sides of the serrations, preventing the damper 34 from falling under the horizontal supporting force, thus limiting the fall of the baffle 31.

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

[0065] The third spring 53 is laterally positioned between the sidewall of the second accommodating space and the sidewall of the sidewall serration 35, with one end fixed to the sidewall of the second accommodating space and the other end connected to the sidewall of the sidewall serration 35. The spring bracket 52 includes an X-shaped movable frame 521 and a handle connecting rod 522. Both ends of the handle connecting rod 522 are fixedly connected to the top ends of the X-shaped movable frame 521, and the four ends of the X-shaped movable frame 521 are respectively fixed to the sidewall serrations 35 on both sides. Furthermore, a movable shaft 523 is provided in the middle of the handle connecting rod 522. By moving this movable shaft 523, the handle connecting rod 522 can be made to form a downwardly concave V-shape or a straight line, and the X-shaped movable frame 521 can open or close its upper and lower ends with its central intersection point as the central axis 524, thereby causing the sidewall serrations 35 on both sides to open or close laterally.

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

[0067] Meanwhile, the bottom of handle 51 is connected to movable shaft 523. When handle 51 is pulled, movable shaft 523 in handle linkage 522 moves upward, causing handle linkage 522 to open, thereby opening the top and bottom ends of X-shaped movable frame 521. The third spring 53 is compressed under the force of X-shaped movable frame 521, increasing the distance between the side wall serrations 35, causing damper 34 to fall between the side wall serrations 35, thereby causing baffle 31 to fall and return to its original position. Understandably, the bottom of baffle 31 can be provided with a component that cooperates with hook 22. When baffle 31 returns to its original position and the water level in water tank 11 makes the first end of lever 21 not lower than the preset height, hook 22 can automatically reconnect with the component at the bottom of baffle 31 for easy use next time.

[0068] In addition, in this application, the force transmission parameters between the components can be referred to the following formula (1):

[0069]

[0070] Where m represents the width of the water tank 11, h0 represents the water level in the water tank 11, l0 represents the length of the water tank 11, ρ represents the density of the water in the water tank 11, l1 represents the length between the pulley 211 and the support point of the force transmission link 212, μ0 represents the vacuum permeability, m1 represents the permeability of the first magnet 13, m2 represents the permeability of the second magnet 41, r represents the distance between the first magnet 13 and the second magnet 41, and k i The spring constant of the second spring, l i F0 represents the displacement of the water tank 11, F0 represents the force required for the hook 22 to disengage, l2 represents the length between the hook 22 and the support point of the force transmission link 212, and n represents a natural number starting from 1.

[0071] The automatic flood control device provided in this application includes a water collection assembly, a transmission assembly, and a baffle assembly. In the first water collection state where flood control is not required, the water volume in the 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 the second water collection state where flood control is required, the water volume in the tank of the water collection assembly is high, causing the first end of the lever in the transmission assembly to fall below the preset height. This displacement of the second end of the lever causes 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. This application can automatically raise the flood control baffle when the water volume exceeds a certain threshold, without the need for manual monitoring and operation, thus achieving automatic disaster response and reducing the impact of disasters.

[0072] The preferred embodiments of this application have been described in detail above. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0073] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0074] Furthermore, various different embodiments of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed by this invention.
