Description

Technical Field

[0001] The present invention belongs to the technical field of flood prevention and water retaining, and more specifically, relates to a non-powered flip-type flood prevention baffle device. Background Art

[0002] At present, most of the entrances of urban community underground parking lots, underground garages, civil air defense works, subways, underground overpasses, etc. are equipped with ordinary steel rolling doors or manual water retaining plates. Due to the low terrain, during the flood season or occasional heavy rain, most of the underground parking lots, underground garages, civil air defense works, subways will be unable to discharge rainwater in time due to overload of drainage systems, resulting in serious property losses and personal injuries due to flooding of vehicles and facilities.

[0003] In the prior art, the lifting of the anti-flooding baffle is usually controlled manually. In an emergency, it is difficult to control the lifting of the anti-flooding baffle in time, which causes rainwater to flow back, causing property damage or casualties. At the same time, the automatic water baffle involved in the prior art uses the torque of the torsion spring to achieve automatic lifting of the water baffle. However, in the device, the connection between the water baffle and the torsion spring is prone to water leakage. At the same time, the water baffle is flipped and lifted by the torsion of the torsion spring or external force when it is not flooded, affecting normal traffic. In addition, the prior art uses a metal frame plus polyurethane foam as a water retaining wall. The specific gravity of the water retaining wall is lighter than water, and it can float after water enters. However, the structure is used to break and damage after being crushed by a heavy object, and it will absorb water instead, resulting in an increase in the weight of the water baffle, making it difficult to float.

[0004] Based on the above defects and shortcomings, there is an urgent need in the art for a non-powered flip-type flood prevention baffle, which is buried within the entrance ground plane during installation and can be installed flush with the ground or slightly above the ground. It does not affect the passage of pedestrians and vehicles on the road at ordinary times. It automatically flips open when flooding occurs to achieve flood prevention without the need for human control. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides a non-powered flip-type anti-flooding baffle device, wherein a non-powered flip-type anti-flooding baffle device is designed in combination with the characteristics of the waterproof and anti-flooding baffle itself and its waterproof and anti-flooding force characteristics, and the structure and specific setting method of its key components such as rubber inclined blocks, water baffles, locking mechanisms, leaf spring mechanisms, limit columns and sealing mechanisms are studied and designed, and the corresponding folding back to the original position does not affect the passage of pedestrians and vehicles on the road when there is no flooding, and it automatically flips open when there is flooding to achieve flood prevention. At the same time, the present invention uses the buoyancy and pressure of water during flooding to achieve automatic locking of the water baffle under the action of gravity when there is no flooding, without affecting normal passage, and automatically unlocks and flips upwards when there is flooding to achieve water blocking by using the buoyancy of water. At the same time, according to different water levels, the water pressure is used to push the flip angle of the water baffle, so that the water baffle automatically adjusts the angle according to the water level without manual assistance, and has the characteristics of simple structure, fast response speed, strong adaptability and fully automatic water blocking. Therefore, it is particularly suitable for applications at the entrances of underground parking lots, underground garages, civil air defense works, subways, underground overpasses, etc.

[0006] To achieve the above-mentioned object, the present invention proposes a non-powered flip-type flood prevention baffle device, comprising: a base, the base is fixedly arranged on the ground;

[0007] An arc-shaped pressing plate, which is fixed on the base and arranged in a lateral direction of the base;

[0008] A water retaining plate, the water retaining plate is a hollow structure;

[0009] The leaf spring mechanism, one end of the leaf spring mechanism is fixedly arranged between the base and the arc pressure plate, and the other end is fixedly connected to the water baffle plate. In this way, the leaf spring mechanism uses the arc pressure plate as a support and a rotating shaft to provide a torque for the water baffle plate to flip upward, and at the same time, a sealing structure is formed on the water-blocking side of the water baffle plate; more specifically, when the base is filled with water, the water baffle plate is lifted upward under the action of buoyancy, and because one end of the leaf spring mechanism is fixedly connected to the leaf spring mechanism, one end of the leaf spring mechanism is fixedly connected to the arc pressure plate, that is, one end of the water baffle plate is fixed and the other end is in a free state. Under the action of buoyancy and the torsion of the leaf spring mechanism, the water baffle plate flips upward with the arc pressure plate as the rotating shaft; the setting of the arc plate provides a rotating shaft and support during the rotation of the leaf spring mechanism, so that the water baffle plate rotates in a specified direction without deflection, which affects the water-blocking function on both sides of the water baffle plate. At the same time, the leaf spring mechanism at the bottom of the water baffle plate is an elastic plate structure, which forms a water-sealing structure between the base and the water baffle plate, further ensuring the water-blocking performance of the overall device;

[0010] A locking mechanism is fixed on the base and is used to lock the water baffle when the water baffle is in a horizontal state, and unlock the water baffle when the water baffle is subjected to the buoyancy of water, so that the water baffle flips upward under the torsion of the leaf spring mechanism and the water pressure. At the same time, when the water recedes, the water baffle, under the action of its own gravity, overcomes the torsion of the leaf spring mechanism and flips downward until the locking mechanism is pressed back and the water baffle further flips downward. When the gravity of the water baffle no longer acts on the locking mechanism, the locking mechanism returns to its position under the action of elastic force, locking the water baffle, so that the water baffle will not flip up under the action of other external forces, affecting normal passage.

[0011] The limit column is arranged in close contact with the wall at the entrance and exit, and when the water retaining plate is in a vertical state, the limit column limits the further turning of the water retaining plate, that is, the limit column makes the maximum turning angle of the water retaining plate be ninety degrees, so that the water retaining height of the water retaining plate is the maximum at this time.

[0012] As a further preferred embodiment, the base includes two horizontal plates and a plurality of vertical plates arranged between the two horizontal plates, and the horizontal plates are fixedly sealed and connected to the ground. In the present invention, since one end of the base is sealed and connected to the leaf spring mechanism, after water enters the other end of the base, the buoyancy of the water directly acts on the water retaining plate, so that the water retaining plate unlocks the locking mechanism under the action of the buoyancy and takes on the water retaining function. Furthermore, in the present invention, the base is connected to the floor by bolts, and a shaft sleeve is provided at each bolt hole.

[0013] As a further preferred embodiment, the water retaining plate includes channel steel, angle steel and multiple parallel rectangular tubes arranged between the channel steel and the angle steel, and the two ends of the rectangular tube are closed. For example, the two ends of the rectangular steel tube are sealed with square steel to form a hollow structure. The channel steel, angle steel and rectangular tube are formed in an integral manner or fixedly connected by welding.

[0014] As a further preferred embodiment, the angle steel is provided with a plurality of connection holes connected to the leaf spring mechanism; the channel steel is arranged horizontally, and one leg of the channel steel hooks the locking mechanism when the water retaining plate is in a horizontal state, so that the water retaining plate is locked by the locking mechanism. That is, in the present invention, the channel steel not only plays the role of water retaining and strengthening, but also plays the role of a locking hook, which hooks the locking mechanism in the absence of water to prevent the water retaining plate from turning up.

[0015] As a further preferred embodiment, the locking mechanism is provided with multiple ones, and the locking mechanism includes a locking support, a lock body, a spring and a lock core. The locking support is fixedly provided on the base, and the lock body is fixedly provided on the locking support. A cavity for accommodating the spring and the lock core is provided in the lock body, and one end of the spring is fixedly connected to the locking support, and the other end is fixedly connected to the lock core.

[0016] As a further preferred embodiment, a pull rod is further included, one end of which is hinged to the water baffle, and the other end of which is hinged to the base, so as to guide and support the water baffle when the water baffle is turned over.

[0017] As a further preference, the water retaining plate is further provided with foldable flexible rubber plates on both lateral sides, and one side of the foldable flexible rubber plates is sealed and fixedly connected to the entrance and exit wall, so that the lateral sides of the water retaining plate are sealed.

[0018] As a further preferred embodiment, a first transverse sealing strip is provided at the connection between the base and the arc pressure plate, a second transverse sealing strip is provided at the connection between the base and the leaf spring mechanism, a second transverse sealing strip pressure plate is also provided on the second transverse sealing strip, and a seal is arranged between the base and the locking mechanism.

[0019] As a further preferred embodiment, it further includes a water baffle head, which is arranged on both lateral sides of the water baffle, and when the water baffle is turned over, the water baffle head is arranged to fit the entrance and exit frame.

[0020] As a further preference, rubber oblique blocks are also provided at both longitudinal ends of the base.

[0021] As a further preferred embodiment, the unpowered flip type flood-proof baffle device is arranged on the ground, and the rubber inclined block is provided with an inclined surface, and the overall height of the unpowered flip type flood-proof baffle device does not affect the normal passage of pedestrians and vehicles; or the unpowered flip type flood-proof baffle device is embedded in the ground, and the top surface of the unpowered flip type flood-proof baffle device is flush with the ground height.

[0022] In general, the above technical solution conceived by the present invention has the following technical advantages compared with the prior art:

[0023] 1. In the present invention, when the device is filled with water, the buoyancy lifts up the water baffle, and the water baffle overcomes the locking force of the locking mechanism and unlocks under the action of the buoyancy and the torsion of the leaf spring mechanism, automatically flips upward, and then automatically flips upward again under the action of the water pressure as the water pressure increases. When the water in the device recedes, the water baffle overcomes the torsion of the leaf spring mechanism and flips downward under the action of its own gravity, and automatically locks by overcoming the locking force of the locking mechanism. That is, in the present invention, the water baffle does not require the monitoring of any control mechanism, and does not require the drive of an electric mechanism. It cleverly uses the buoyancy and pressure of water to achieve automatic upward flipping to block water under flooding conditions without power, and automatically returns to its original position and locks after the water recedes, without affecting traffic. It has a simple structure and strong anti-flooding and water-blocking capabilities.

[0024] 2. The device of the present invention has no locking device when flooding, so that the anti-flooding baffle is stably in the horizontal plane. When flooding, under the action of buoyancy, the locking device is automatically unlocked, and the baffle is flipped open under the action of the leaf spring and water pressure. The flipping angle increases with the water level until the maximum water retaining height is reached when it is vertical to the ground.

[0025] 3. The present invention uses leaf springs and arc-shaped pressure plates as the rotating shafts for the flipping movement of the water baffle, and provides torque for the flipping movement of the water baffle, so that the water baffle can flip along a predetermined arc without deviation, and at the same time, the leaf spring mechanism plays the role of sealing and blocking water below the device. The present invention cleverly uses the gravity and buoyancy of the water baffle itself and the torque provided by the leaf spring and arc-shaped pressure plate, so that the water baffle is automatically locked in a non-flooded state without affecting traffic, and automatically flips and rises in a flooded state to prevent water backflow, and has the characteristics of simple structure and fast response.

[0026] 4. The device of the present invention does not require electric drive or control mechanism monitoring. On the one hand, it avoids the danger caused by the contact between electricity and water. On the other hand, it automatically flips upward to block water when the water level rises and automatically locks when the water level recedes. It has strong self-adaptation ability, high safety performance, long practical life and low maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figures 1 to 6 As shown, an embodiment of the present invention provides a non-powered flip anti-flooding baffle device, which is an integral sealing structure and can be arranged on the ground at the entrance or exit, or can be embedded in the ground at the entrance or exit. That is, the non-powered flip anti-flooding baffle device is arranged on the ground, and the rubber inclined block 1 is provided with an inclined surface, and the overall height of the non-powered flip anti-flooding baffle device does not affect the normal passage of pedestrians and vehicles, or the non-powered flip anti-flooding baffle device is embedded in the ground, and the top surface of the non-powered flip anti-flooding baffle device is flush with the ground height.

[0036] Specifically, Figure 1 , Figure 2 as well as Figure 3As shown, the device of the present invention includes a base 2, which is fixedly arranged on the ground. The base 2 is the foundation of the present device, and is fixedly and sealedly connected to the ground. The base 2 includes two transverse plates and a plurality of longitudinal plates arranged between the two transverse plates, and the transverse plates are fixedly and sealedly connected to the ground. A cavity structure is formed between the two transverse plates, and the cavity structure can be used as a water storage cavity. However, the water storage cavity may not be used in the present invention, that is, the present invention directly utilizes the water sealing mechanism composed of the base, the arc pressure plate 5, the leaf spring mechanism and the water retaining plate. When the water sealing structure is flooded, water cannot penetrate the water sealing structure, and at the same time directly provides the water retaining plate with upward buoyancy. Specifically, an arc pressure plate 5 is fixedly arranged above one of the transverse plates of the base 2, and the arc pressure plate 5 is arranged parallel to the transverse plate, that is, the arc pressure plate 5 is fixedly arranged on the base 2, and the arc pressure plate 5 is arranged along the lateral direction of the base 2. In a preferred embodiment of the present invention, the arc pressure plate 5 includes an integrally formed arc plate and a connecting plate, wherein the connecting plate is fixedly connected to the base 2 by bolts or other connection methods, and the opening direction of the arc plate is arranged facing the other horizontal plate. The arc plate is a rigid structure and will not deflect or deform under a certain pressure. The device also includes a leaf spring mechanism 6 and a water baffle 10, wherein one end of the leaf spring mechanism 6 is fixedly arranged between the base 2 and the arc pressure plate 5, and the other end is fixedly connected to the water baffle 10. The curvature direction of the arc pressure plate 5 is consistent with the curvature direction of the leaf spring mechanism, and in this way, when the water baffle 10 applies external force to the mechanism 6, the leaf spring mechanism 6 rotates and deforms with the arc pressure plate 5 as the shaft and support. More specifically, one end of the leaf spring mechanism is fixedly arranged between the base and the arc pressure plate, and the other end is fixedly connected to the water baffle plate. In this way, the leaf spring mechanism uses the arc pressure plate as a support and a rotating shaft to provide a torque for the water baffle plate to flip upward, and at the same time, a sealing structure is formed on the water-blocking side of the water baffle plate; more specifically, when the water storage chamber in the base is filled with water, the water baffle plate is lifted upward under the action of buoyancy, because one end of the leaf spring mechanism is fixedly connected to the leaf spring mechanism, and one end of the leaf spring mechanism is fixedly connected to the arc pressure plate, that is, one end of the water baffle plate is fixed and the other end is in a free state. Under the action of buoyancy and the torsion of the leaf spring mechanism, the water baffle plate flips upward with the arc pressure plate as the rotating shaft; the setting of the arc plate provides a rotating shaft and support during the rotation of the leaf spring mechanism, so that the water baffle plate rotates in a specified direction without deflection, which affects the water-blocking function on both sides of the water baffle plate. At the same time, the leaf spring mechanism at the bottom of the water baffle plate is an elastic plate structure, which forms a water-sealing structure between the base and the water baffle plate, further ensuring the water-blocking performance of the overall device. In the present invention, the leaf spring mechanism includes a leaf spring, which is a continuous elastic plate structure, one end of which is arranged between the base 2 and the arc pressure plate 5, and the other end is connected to a sealed hollow structure. At the same time, a sealing treatment is performed at the connection between the leaf spring and the base 2 and the arc pressure plate 5, so that one end of the leaf spring arranged on the base 2 is a water-sealing structure, thereby playing a role in sealing and blocking water at the bottom of the device.

[0037] In the present invention, the water baffle 10 is a hollow structure. In one embodiment of the present invention, the water baffle 10 includes a channel steel, an angle steel, and a plurality of rectangular tubes arranged in parallel between the channel steel and the angle steel, and the two ends of the rectangular tube are closed to form a hollow structure. The channel steel, the angle steel, and the rectangular tube are formed in an integral manner, or are fixedly connected by welding. The angle steel is provided with a plurality of connection holes connected to the leaf spring mechanism 6. The channel steel is arranged horizontally, and one leg of the channel steel hooks the locking mechanism 3 when the water baffle 10 is in a horizontal state, so that the water baffle 10 is locked by the locking mechanism 3. In another embodiment of the present invention, the water baffle includes a plate body with a hollow structure, and ribs arranged crosswise in the hollow structure. In the present invention, the water baffle 10 has the performance of floating under the action of water buoyancy, that is, in the stage of unlocking the locking mechanism of the water baffle, the buoyancy is used as the power for unlocking, and the buoyancy and the torsion of the leaf spring jointly overcome the locking force of the locking mechanism and the gravity of the water baffle. At the same time, the water retaining plate has a waterproof performance. In one embodiment of the present invention, the water retaining plate is made of steel, and it will not cause problems such as material damage or buoyancy reduction due to multiple water retaining.

[0038] The structure of the device also includes a locking mechanism 3, and a locking hook is also provided at the end of the water baffle 10 close to the locking mechanism 3. When the free end of the water baffle 10 is provided with a channel steel, one leg of the channel steel is used as a locking hook to cooperate with the locking mechanism 3, or an L-shaped locking hook is provided at the free end of the plate body to correspond to the locking mechanism 3. There are multiple locking mechanisms 3, and the locking mechanism 3 includes a locking support, a lock body, a spring and a lock core. The locking support is fixedly provided on the base 2, and the lock body is fixedly provided on the locking support. A cavity for accommodating the spring and the lock core is provided in the lock body, and one end of the spring is fixedly connected to the locking support, and the other end is fixedly connected to the lock core. The locking mechanism 3 is used to lock the water baffle 10 when the water baffle 10 is in a horizontal state. The lock core is a conical structure. When the water baffle 10 flips upward under the action of buoyancy, the lock hook stops on the lock core and gradually compresses the spring, causing the lock core to retreat, thereby causing the lock hook to disengage from the lock core. The upward turning force of the water baffle 10 is provided by the water pressure in the device. When the water recedes, the gravity of the water baffle 10 overcomes the torque of the leaf spring mechanism and returns downward, and gradually compresses the spring, causing the lock core to retreat. When the lock hook is below the lock core, the pressure of the spring is released and the lock core returns, thereby locking the lock hook. At this time, the top surface height of the water baffle 10 is consistent with the top surface of the rubber ramp 1 or the ground height, and does not affect normal passage.

[0039] like Figure 3As shown, in a preferred embodiment of the present invention, a transverse sealing strip 4 is provided between the arc pressure plate 5 and the base, a second transverse sealing strip 7 is provided at the connection between the base 2 and the leaf spring mechanism 6, and a second transverse sealing strip pressure plate 8 is further provided on the second transverse sealing strip 7, and a sealing arrangement is provided between the base 2 and the locking mechanism 3. The leaf spring mechanism 6 plays the role of the water baffle rotating shaft, and can provide the water baffle 10 with a turning moment when it is opened, and the arc pressure plate 5 provides support and positioning for the leaf spring mechanism 6 when it rotates. That is, the rotating shaft end of the water baffle 10 is provided with an arc pressure plate 5 and a leaf spring mechanism 6. The arc pressure plate 5 is arranged on the inner side of the rubber inclined block 1 without the locking mechanism 3, one end of the leaf spring mechanism 6 is fixedly connected between the ground and the rubber inclined block 1 without the locking mechanism 3, and the other end is connected to the water baffle 10, and the leaf spring mechanism 6 is supported by the arc surface of the arc pressure plate 5, and provides a moment for the water baffle 10 to turn upward with the arc pressure plate 5 as the rotating shaft. In one embodiment of the present invention, the leaf spring mechanism 6 includes a leaf spring and a connecting member connecting and fixing the leaf spring. The leaf spring acts as a rotating shaft of the water baffle plate and can provide a turning torque to the water baffle plate 10 when it is opened.

[0040] like Figure 1 , Figure 2 as well as Figure 3 As shown, the device of the present invention also includes a limiting column, which is arranged in close contact with the wall at the entrance and exit, and when the water baffle 10 is in a vertical state, the limiting column limits the water baffle 10 from further turning in the direction away from the locking mechanism 3, so that the water baffle 10 can maintain a vertical state under a large water pressure, and avoid the water baffle 10 from turning over. More specifically, the height of the limiting column is at least not less than the height of the water baffle 10, and the limiting column is arranged in close contact with the wall of the entrance and exit, and is sealed and connected to the wall. In one embodiment of the present invention, the limiting column is an L-shaped structure, the opening direction of the L-shaped structure is toward the water baffle 10, and one side plate of the limiting column is sealed and connected to the wall. In one embodiment of the present invention, one side plate of the limiting column can be embedded in the wall. In another embodiment of the present invention, a sealing material can be filled between the limiting column and the wall. Other sealing structures are applicable to the present invention. Similarly, because the limiting column has a T-shaped structure, the panel of the T-shaped structure is sealed and connected to the wall.

[0041] like Figure 5As shown, in a preferred embodiment of the present invention, a foldable flexible rubber sheet 15 is further provided on both lateral sides of the water retaining plate 10, and one side of the foldable flexible rubber sheet 15 is sealed and fixedly connected to the entrance and exit wall. The two sides of the foldable flexible rubber sheet 15 are connected by pressure strips. The two ends of the water retaining plate 10 are sealed by the water retaining plate head 11 to form a hollow structure with high strength. When flooded, the hollow structure of the water retaining plate 10 generates buoyancy, the locking device 3 is unlocked, and the water retaining plate 10 begins to flip under the action of the leaf spring. As the water level increases, the flipping angle of the water retaining plate 10 increases continuously with the water level, and the foldable flexible rubber sheets 15 on both sides are folded accordingly, and the water flow between the gaps on both sides is blocked. When the water level reaches the highest water retaining height, the water retaining plate is perpendicular to the ground, and the foldable flexible rubber sheet 15 is unfolded. That is, in the present invention, the water retaining plate 10, the foldable flexible rubber plates 15 arranged at its two lateral ends, the arc pressure plate and the leaf spring together form a sealed cavity, which blocks water in the cavity at one end of the base, so that water cannot pass through the water retaining plate 10 and the gaps around it, thereby realizing the functions of flood prevention and water retaining.

[0042] In a preferred embodiment of the present invention, the device further comprises a pull rod 9, which is used to guide and support the water baffle 10 when the water baffle 10 is turned over. More specifically, in the present invention, one end of the pull rod 9 is hinged to the water baffle 10, and the other end is hinged to the ground or the base 2. The pull rod 9 comprises two connecting rods connected in sequence, and the two connecting rods are movably connected. When the water baffle 10 is in a horizontal state, the two connecting rods are in a folded state, that is, folded with the connection point as the folding point. When the water baffle 10 is turned upward, the two connecting rods are unfolded with the connection point as the rotation point, and guide the rotation of the water baffle 10. In one embodiment of the present invention, the two connecting rods are movably connected by a torsion spring. When the water baffle 10 is in a vertical state, the two connecting rods are straightened to form a colinear rod, which is used to further support the water baffle 10 and strengthen the supporting force of the water baffle 10.

[0043] like Figure 5 and Figure 6 As shown, in the present invention, when the device is set on the ground, the two rubber inclined blocks 1 are both provided with inclined surfaces, and the two inclined surfaces are arranged opposite to each other, which are used to buffer the resistance when people, cars or other things pass through. The slope of the inclined surface can be designed according to the actual situation. Generally speaking, the slope is not greater than 45°. When the device is embedded in the ground, the top surface of the device is flush with the ground, and the rubber inclined blocks can be set as a square structure. If the rubber inclined blocks are still provided with inclined surfaces, fillers can be set on the inclined surfaces so that the top surface of the fillers is flush with the ground to facilitate passage. At the same time, a water inlet connected to the base 2 is also provided on the ground to allow water on the ground to quickly enter the base.

[0044] The device of the present invention can also be modularly configured, that is, the device of the present invention is a module unit, and lateral connecting plates are provided on both sides of the base in the longitudinal direction. The limit column and the foldable flexible rubber plate 15 are no longer connected to the wall, but are connected to the lateral connecting plates to form a module unit. The transverse length of the module unit can be designed according to actual needs, such as 0.5 meters, 0.9 meters, 1 meter, etc., and the longitudinal length of the module unit needs to be designed according to the required water retaining height at the water retaining place. For example, if the water retaining height at a certain outlet is not less than 2 meters, then the height of the water retaining plate shall not be less than 2 meters. On the basis of meeting the requirements, a proper margin can be left. Then multiple module units are assembled and welded in the transverse direction to form a whole.

[0045] The specific working process of the device of the present invention is as follows: when there is no flooding, the lock tongue and lock hook of the locking mechanism cooperate to lock the water baffle. At this time, the upper surface of the water baffle is flush with the upper surface of the rubber inclined block or the ground, and does not affect normal passage. When the base is flooded, the water provides the water baffle with upward buoyancy. Since one end of the water baffle is a fixed end, the other end overcomes its own gravity and the locking force of the locking mechanism under the action of buoyancy and the return torque of the leaf spring, that is, the lock hook presses the spring to make the lock core retreat, the lock hook is separated from the lock core, and the water baffle is automatically unlocked. As the water level rises, the water pressure on the flooded side of the water baffle further increases, and the water pressure pushes the water baffle to continue to flip upward with the support shaft of the arc pressure plate and the leaf spring mechanism as the rotating shaft. The foldable flexible rubber prevents water from passing through the lateral sides of the water baffle. When the water baffle flips upward to a vertical state, the limit column limits the further flipping of the water baffle. At this time, the water baffle blocks water outside the entrance and exit to achieve the water blocking function. As the water level drops, the water pressure on the water baffle decreases, and the water baffle gradually flips downward under its own gravity. When the water level recedes completely, the gravity of the water baffle overcomes the locking force of the locking mechanism and the torsion of the leaf spring, that is, the lock hook pushes the lock core backward until the lock hook is under the lock core, the spring returns and pushes the lock core forward, locking the lock hook, and the water baffle returns to its position without affecting normal passage.

[0046] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
