Description

Technical Field

[0001] The present invention relates to the technical field of flood control in water conservancy projects, and particularly relates to a flood control device and a flood control method for water conservancy projects. Background Art

[0002] Flood is a natural phenomenon, but it is extremely harmful. Therefore, flood control personnel study and adopt various countermeasures and measures according to the laws of floods and the characteristics of flood disasters to prevent or mitigate flood disasters, ensure the water conservancy work for social and economic development, and then use flood control devices to avoid the overflow of floods.

[0003] Existing flood control devices are not convenient for rapid erection and use. Usually, only flood control sandbags can be used to block floods, so the flood fighting effect and stability are poor. When flood control baffles are used for flood control, most flood control baffles are fixed, which is not convenient for adjusting the flood control area and cannot provide timely protection.

[0004] A flood control device for water conservancy projects with the publication number of CN219410724U includes a support platform. A counterweight housing is installed on one side of the top of the support platform, and an adjustable flood control mechanism is arranged on the other side of the top of the support platform; when the support sub-board is pulled out, the whole reinforcement assembly moves accordingly. Then, under the action of the reinforcement rod, the overall support performance is effectively improved, so that the flood control baffle can adjust the flood control area, thereby achieving timely protection. When the support main board and the support sub-board cannot meet the blocking requirements, multiple sets of this device can be added on-site for mutual splicing. Since limit slots are symmetrically opened at one end of the support platform, and connecting rods are slidably installed in the limit slots, first, the connecting rods are inserted into the limit slots, and then the limit slots on another device are clamped onto the connecting rods, so that multiple devices can be mutually spliced, further improving the practicability.

[0005] In the above technical solution, the blocking is achieved by the flipping of the plate body to achieve the flood control effect. However, it cannot be effectively applied to the dam and cannot be adjusted automatically according to the flood situation, so improvement is needed. Summary of the Invention

[0006] The purpose of the present invention is to solve the deficiencies in the prior art and propose a flood control device and a flood control method for water conservancy projects.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A flood control device for water conservancy projects includes a dam assembly. An inclined baffle member is hinged to the inclined end of the dam assembly, and a lifting mechanism is arranged at the inclined end of the dam assembly. The lifting mechanism is connected to the inclined baffle member;

[0009] There are two pressing rods on the lifting mechanism. A bearing notch is opened at the upper end of the dam assembly. A lifting baffle is slidably installed in the bearing notch. A linkage mechanism is provided on the lifting baffle, and the linkage mechanism is connected to the two pressing rods;

[0010] First connection grooves and second connection grooves are respectively opened from top to bottom on both sides of the lifting baffle. A through port is commonly penetrated between the first connection groove and the second connection groove on the same side. A regulation mechanism is provided in one of the first connection grooves. A first abutting block and a horizontal shaft are provided on the regulation mechanism. A contact sealing mechanism is provided on the horizontal shaft. The first abutting block is slidably installed in one of the first connection grooves. A flipping mechanism is provided in the other first connection groove. The flipping mechanism penetrates through the other through port and extends into the other second connection groove. A top plate is provided on the flipping mechanism.

[0011] Compared with the prior art, the present application can impact the inclined baffle member by flood, so that the inclined baffle member operates to make components such as the pressing rod, the flipping rod, the linkage plate and the pulling rope cause the lifting baffle to rise, so as to effectively carry out flood control operations, effectively block floods, and at the same time facilitate the connection and fixation between multiple devices to form a protective wall, and ensure the firmness and tightness of the connection, avoid penetration, and ensure the flood control effect.

[0012] Preferably, the lifting mechanism includes two sliding grooves provided on the inclined surface of the dam assembly. A sliding block is slidably installed in the sliding groove. A swinging member is rotatably connected between the sliding block and the inclined baffle member. A positioning mechanism is connected to the upper end of the sliding block;

[0013] A rubber seal is jointly connected between the inclined baffle member and the rubber seal.

[0014] Furthermore, when the inclined baffle member is impacted by flood, the inclined baffle member flips towards the dam assembly, so that the swinging member pushes the sliding block to rise along the sliding groove, and the stability of positioning after the impact can be ensured through the positioning mechanism to ensure the stability of the height of the lifting baffle.

[0015] Preferably, the positioning mechanism includes a vertical plate member fixed to the middle of the upper end of the sliding block. Swing plates are respectively hinged to both sides of the upper end of the vertical plate member. A resistance spring member is jointly fixed between the swing plate and the vertical plate member;

[0016] An insertion groove is opened at the upper end of the sliding groove. An insertion port is jointly opened between the insertion groove and the sliding groove. The insertion port corresponds to the vertical plate member.

[0017] Furthermore, when the sliding block ascends along the sliding groove, it can make the swing plate contact the insertion interface, and the resistance spring member is compressed. The swing plate can extend into the insertion groove through the insertion interface. After the swing plate enters the insertion groove, the resistance spring member can push the swing plate to flip, making the swing plate contact the bottom in the insertion groove, effectively fixing the position of the inclined baffle member and fully squeezing the pressing rod, so that the height position of the lifting baffle is fixed.

[0018] Preferably, the linkage mechanism includes a linkage plate slidably mounted on one end side wall in the bearing notch. The linkage plate is equidistantly installed with lifting wire winding wheel assemblies. A fixed wire winding wheel assembly is installed on one end side wall in the bearing notch. The linkage plate is located above the fixed wire winding wheel assembly. A pull rope is jointly sleeved between the lifting wire winding wheel assembly and the fixed wire winding wheel assembly. The two lower ends of the pull rope are respectively fixed on both sides of the lifting baffle. Rotating rods are respectively rotatably connected to both sides of the linkage plate. The two rotating rods are respectively rotatably connected to one end of the two pressing rods extending into the bearing notch.

[0019] Furthermore, when the pressing rod is squeezed, it can pull the rotating rod to move, making the rotating rod rotate horizontally. This will cause the linkage plate to ascend. The ascending of the linkage plate can drive the lifting wire winding wheel assembly to ascend. Through the multiple wire winding wheel components in the lifting wire winding wheel assembly, the stretching condition of the pull rope can be improved, so as to fully drive the lifting baffle to ascend. It can achieve that a small movement of the linkage plate drives the lifting baffle to ascend in a large range, effectively expanding the overall height of the lifting baffle and the dam assembly, and fully playing the flood control effect.

[0020] Preferably, the regulation mechanism includes a screw member rotatably connected to the upper end of the lifting baffle. The lower end of the screw member extends into one of the first connection grooves. A threaded sleeve is threadedly sleeved on the lower end of the screw member. One side of the lower end of the threaded sleeve is rotatably connected to a push rod. The lower end of the push rod and one end of the first contact block located in the first connection groove are rotatably connected. The cross shaft is fixed to the other side of the lower end of the threaded sleeve.

[0021] Furthermore, by controlling the rotation direction of the screw member, the lifting condition of the threaded sleeve can be effectively adjusted. When the threaded sleeve descends, it can make the push rod push the first contact block to move, so that the first contact block can be inserted into the first connection groove of another device. At the same time, the descending of the threaded sleeve can drive the cross shaft to descend.

[0022] Preferably, the interference sealing mechanism includes a lifting opening formed in one of the first connection grooves. One end of the lifting baffle is provided with a notch, the notch is disposed on one side of one of the first connection grooves, a moving plate is slidably installed in the notch, a sealing member is fixed to the end of the moving plate located outside the lifting baffle, the horizontal shaft penetrates through the lifting opening and extends into the notch, a turntable member is rotatably sleeved at the end of the horizontal shaft extending into the notch, two interference shafts are rotatably sleeved on one side of the turntable member, a swing rod is jointly abutted between the two interference shafts, the lower end of the swing rod is rotatably connected to one side wall of the notch, and the upper end of the swing rod is rotatably connected to a lifting block, and the lifting block is slidably installed on one side of the moving plate.

[0023] Further, when the horizontal shaft descends, the turntable member can be lowered. By driving the interference shafts to lift and lower through the turntable member, and the interference shafts abut against the swing rod. When the interference shafts descend, the swing rod can be deflected, and the deflection of the swing rod can push the lifting block to descend, so that the moving plate is pushed, and the moving plate can be pushed to make the sealing member abut against another lifting baffle, effectively achieving sealing.

[0024] Preferably, the flipping mechanism includes a connecting rod disposed in another first connection groove. The connecting rod penetrates through another through opening and extends into another second connection groove. A second interference block is slidably installed in another second connection groove. The lower end of the connecting rod is rotatably connected to a push rod, and one end of the push rod is rotatably connected to one side of the second interference block. A clamping mechanism is provided at the upper end of the second interference block.

[0025] Further, when the first interference block is inserted into another first connection groove, the first interference block can squeeze the connecting rod to deflect, so that the connecting rod pushes the push rod to make the second interference block insert into one of the second connection grooves. At the same time, the clamping mechanism can be inserted into another inclined baffle member to complete the connection and fixation of the two inclined baffle members.

[0026] Preferably, the clamping mechanism includes a connecting rod formed in the upper end of the second interference block. A return spring member is fixed to the bottom in the connecting rod, and the lower end of the top plate is fixed to the upper end of the return spring member.

[0027] Further, the return spring member pushes the top plate to rise, which can make the top plate and the inclined block in another inclined baffle member rise to complete the connection and fixation of the two inclined baffle members.

[0028] Preferably, an inclined block is installed in one of the through openings, and the inclined block abuts against the first interference block.

[0029] Further, when the first interference block is reset, the first interference block can squeeze the inclined block, so that the top plate retracts into the installation groove, facilitating the separation of the two inclined baffle members.

[0030] The present invention also provides a flood control method for a flood control device used in a water conservancy project, which includes the following steps:

[0031] S1. Assembly of the water retaining dam: Arrange multiple inclined baffle members in sequence, with the seal on one lifting baffle corresponding to the end without a seal on another lifting baffle; the staff controls the rotation of the screw member and the rotation direction of the screw member, so that the screw member pushes the threaded sleeve downward. When the threaded sleeve descends, it can push the first abutting block into the first connection groove without the first abutting block in another lifting baffle through the push rod. The first abutting block can squeeze the connecting rod in another lifting baffle, so that the connecting rod pushes the push rod and the second abutting block into the second connection groove without the second abutting block in the original lifting baffle. Through the reset spring member and the top plate, the top plate can rise and be inserted into the second connection groove without the second abutting block in the original lifting baffle, and can be inserted into the corresponding through hole to complete the connection of the two lifting baffles and the connection of the two inclined baffle members. At the same time, when installing, a sealing gasket component can be added between adjacent two inclined baffle members to complete the sealing between the two inclined baffle members;

[0032] S2. Sealing and anti-seepage: When the threaded sleeve descends, it can drive the turntable member and two abutting shafts through the horizontal axis to make the swing rod flip, so as to push the moving plate and the seal towards another lifting baffle, so that the seal is squeezed to achieve the sealing effect;

[0033] S3. Basic flood control: When the water wave of the flood comes, the water wave impacts the inclined baffle member, causing the inclined baffle member to flip towards the dam assembly. However, the inclined baffle member is inclined and sealed by the rubber seal, so that the water wave can flow back along the surface of the inclined baffle member. And when the water surface rises slowly, it will also make the water squeeze the inclined baffle member, causing the inclined baffle member to rotate towards the dam assembly;

[0034] S4. Flood control when the flood intensifies: When the water wave of the flood is large, it can make the inclined baffle member push the swing member so that the sliding block rises along the sliding groove. The vertical plate member and the swing plate at the upper end of the sliding block can penetrate the insertion opening and enter the insertion groove. The swing plate is pushed to unfold through the resistance spring member to fix the position of the sliding block. The sliding block can squeeze the pressing rod member to make the turning rod rotate, so as to pull the linkage plate upward. The pull rope is pulled through the multiple lifting and winding wheel assemblies on the linkage plate, so as to drive the lifting baffle to rise and limit the position height of the lifting baffle to achieve the flood control effect.

[0035] The beneficial effects of the present invention are:

[0036] 1. When the inclined baffle member is impacted by the flood, the inclined baffle member flips towards the dam assembly, so that the swing member pushes the sliding block to rise along the sliding groove, and the stability of the positioning after the impact can be ensured through the positioning mechanism to ensure the stability of the height of the lifting baffle;

[0037] 2. When the sliding block rises along the sliding groove, it can make the swing plate contact the insertion interface, and the resistance spring member is compressed. The swing plate can extend into the insertion groove through the insertion interface. After the swing plate enters the insertion groove, the resistance spring member can push the swing plate to flip, so that the swing plate contacts the bottom in the insertion groove, effectively fixing the position of the inclined baffle member and fully squeezing the pressing rod member, so that the height position of the lifting baffle is fixed;

[0038] 3. When the pressing rod member is squeezed, it can pull the flipping rod to move, making the flipping rod rotate horizontally. This will cause the linkage plate to rise. The rising of the linkage plate can drive the lifting wire winding wheel assembly to rise. Through the multiple wire winding wheel components in the lifting wire winding wheel assembly, the stretching of the pulling rope can be improved, so as to fully drive the lifting baffle to rise. It can achieve that a small movement of the linkage plate drives the lifting baffle to rise in a large range, effectively expanding the overall height of the lifting baffle and the dam assembly, and fully playing a flood control effect;

[0039] 4. By controlling the rotation direction of the screw rod member, the lifting of the threaded sleeve can be effectively adjusted. When the threaded sleeve descends, it can make the push rod push the first contact block to move, so that the first contact block is inserted into the first connection groove of another device. At the same time, the descent of the threaded sleeve can drive the cross shaft to descend;

[0040] 5. The descent of the cross shaft can make the turntable member descend. The turntable member drives the contact shaft to lift and lower. The contact shaft contacts the swing rod. When the contact shaft descends, it can make the swing rod deflect. The deflection of the swing rod can push the lifting block to descend, so that the moving plate is pushed. The moving plate can push the sealing member to contact another lifting baffle, effectively achieving sealing;

[0041] 6. When the first contact block is inserted into another first connection groove, it can make the first contact block squeeze the connecting rod to deflect, so that the connecting rod pushes the push rod to make the second contact block inserted into one of the second connection grooves. At the same time, it can be inserted into another inclined baffle member through the clamping mechanism to complete the connection and fixation of the two inclined baffle members;

[0042] 7. The reset spring member pushes the top plate to rise, which can make the top plate and the inclined block in another inclined baffle member rise to complete the connection and fixation of the two inclined baffle members; when the first contact block resets, it can make the first contact block squeeze the inclined block, so that the top plate retracts into the installation groove, facilitating the separation of the two inclined baffle members.

Detailed implementation manners

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0053] Referring to Figures 1-8 , a flood control device for water conservancy projects includes a dam assembly 1. The inclined end of the dam assembly 1 is hinged with an inclined baffle member 2. A lifting mechanism is provided at the inclined end of the dam assembly 1. The lifting mechanism is connected to the inclined baffle member 2. By means of the lifting mechanism, the impact force of the water wave of the flood can be converted into the force for the operation of corresponding components, so as to control the lifting or positioning of the lifting baffle 4, so as to fully achieve the flood control effect.

[0054] Referring to Figures 1-8, the lifting mechanism includes two sliding grooves 7 arranged on the inclined surface of the dam component 1. A sliding block 11 is slidably installed in the sliding groove 7. A swinging member 12 is rotatably connected between the sliding block 11 and the inclined baffle member 2. The upper end of the sliding block 11 is connected with a positioning mechanism. When the inclined baffle member 2 is impacted by flood water, the inclined baffle member 2 is flipped towards the dam component 1, so that the swinging member 12 pushes the sliding block 11 to rise along the sliding groove 7, and the positioning mechanism can ensure the stability of positioning after the impact to ensure the stability of the height of the lifting baffle 4. A rubber seal 3 is connected between the inclined baffle member 2 and the rubber seal 3. Through the action of the rubber seal 3, effective sealing can be carried out to prevent water waves from flowing through the gap between the inclined baffle member 2 and the dam component 1, and fully ensure that the force of the water wave is applied to the inclined baffle member 2.

[0055] Refer to Figures 1-8 , the positioning mechanism includes a vertical plate member 13 fixed to the middle of the upper end of the sliding block 11. Swing plates 9 are hinged on both sides of the upper end of the vertical plate member 13. A resistance spring member 10 is fixed between the swing plate 9 and the vertical plate member 13. An insertion groove 5 is opened at the upper end of the sliding groove 7. An insertion port 6 is opened between the insertion groove 5 and the sliding groove 7. The insertion port 6 corresponds to the vertical plate member 13. When the sliding block 11 rises along the sliding groove 7, the swing plate 9 can be in contact with the insertion port 6, and the resistance spring member 10 is compressed, so that the swing plate 9 can extend into the insertion groove 5 through the insertion port 6. When the swing plate 9 enters the insertion groove 5, the resistance spring member 10 can push the swing plate 9 to flip, so that the swing plate 9 is in contact with the bottom in the insertion groove 5, which can effectively fix the position of the inclined baffle member 2 and fully squeeze the pressure rod member 8 to fix the position and height of the lifting baffle 4.

[0056] Refer to Figures 1-8 , two pressure rod members 8 are provided on the lifting mechanism. A bearing notch is opened at the upper end of the dam component 1. A lifting baffle 4 is slidably installed in the bearing notch. A linkage mechanism is provided on the lifting baffle 4. The linkage mechanism is connected with the two pressure rod members 8. Through the action of the linkage mechanism, the force of the water wave impacting the inclined baffle member 2 can be converted into the force for the lifting baffle 4 to lift, which is convenient for blocking the impact of the water wave.

[0057] Refer to Figures 1-8, the linkage mechanism includes a linkage plate 14 slidably installed on one end sidewall within the bearing notch. Equally spaced lifting winding wheel assemblies 38 are installed on the linkage plate 14. A fixed winding wheel assembly 40 is installed on one end sidewall within the bearing notch. The linkage plate 14 is located above the fixed winding wheel assembly 40. A pulling rope 39 is commonly sleeved between the lifting winding wheel assembly 38 and the fixed winding wheel assembly 40. The two sides of the lower end of the pulling rope 39 are respectively fixed to the two sides of the lifting baffle 4. Rotating rods 37 are rotatably connected to both sides of the linkage plate 14. The two rotating rods 37 are respectively rotatably connected to one end of the two pressure rods 8 extending into the bearing notch. When the pressure rod 8 is squeezed, it can pull the rotating rod 37 to move, causing the rotating rod 37 to rotate horizontally. This will cause the linkage plate 14 to rise. The rising of the linkage plate 14 can drive the lifting winding wheel assembly 38 to rise. Through the multiple winding wheel components within the lifting winding wheel assembly 38, the stretching situation of the pulling rope 39 can be improved, thereby fully driving the lifting baffle 4 to rise. It can achieve that a small movement of the linkage plate 14 drives the lifting baffle 4 to rise over a large range, effectively expanding the overall height of the lifting baffle 4 and the dam assembly 1, and fully playing the flood prevention effect.

[0058] Refer to Figures 1-8 , first connection grooves 18 and second connection grooves 32 are formed from top to bottom on both sides of the lifting baffle 4. A through opening 19 is commonly penetrated between the first connection groove 18 and the second connection groove 32 on the same side. A regulation mechanism is provided in one of the first connection grooves 18. The regulation mechanism is provided with a first abutting block 31 and a horizontal shaft 35. The positions of the first abutting block 31 and the horizontal shaft 35 can be controlled through the regulation mechanism.

[0059] Refer to Figures 1-8 , the regulation mechanism includes a screw member 30 rotatably connected to the upper end of the lifting baffle 4. The lower end of the screw member 30 extends into one of the first connection grooves 18. A threaded sleeve 34 is threadedly sleeved on the lower end of the screw member 30. One side of the lower end of the threaded sleeve 34 is rotatably connected to a push rod 36. The lower end of the push rod 36 is rotatably connected to one end of the first abutting block 31 located within the first connection groove 18. The horizontal shaft 35 is fixed to the other side of the lower end of the threaded sleeve 34. By controlling the rotation direction of the screw member 30, the lifting situation of the threaded sleeve 34 can be effectively adjusted. When the threaded sleeve 34 descends, it can cause the push rod 36 to push the first abutting block 31 to move, so that the first abutting block 31 can be inserted into the first connection groove 18 of another device. At the same time, the descent of the threaded sleeve 34 can drive the horizontal shaft 35 to descend.

[0060] Refer to Figures 1-8, a contact sealing mechanism is provided on the horizontal axis 35. The contact sealing mechanism includes a lifting opening 27 formed in one of the first connection grooves 18. One end of the lifting baffle 4 is provided with a notch 15. The notch 15 is disposed on one side of one of the first connection grooves 18. A moving plate 16 is slidably installed in the notch 15. A sealing member 17 is fixed to the end of the moving plate 16 located outside the lifting baffle 4. The horizontal axis 35 passes through the lifting opening 27 and extends into the notch 15. One end of the horizontal axis 35 extending into the notch 15 is rotatably sleeved with a turntable member 28. Two contact shafts 29 are rotatably sleeved on one side of the turntable member 28. A swing rod 26 is jointly contacted between the two contact shafts 29. The lower end of the swing rod 26 is rotatably connected to one end side wall in the notch 15. The upper end of the swing rod 26 is rotatably connected to a lifting block 25. The lifting block 25 is slidably installed on one side of the moving plate 16; when the horizontal axis 35 descends, the turntable member 28 can be made to descend. The contact shafts 29 are driven by the turntable member 28 to lift and lower. The contact shafts 29 contact the swing rod 26. When the contact shafts 29 descend, the swing rod 26 can be deflected. The deflection of the swing rod 26 can push the lifting block 25 to descend, so that the moving plate 16 is pushed, and the moving plate 16 can be made to push the sealing member 17 to contact another lifting baffle 4, effectively achieving sealing.

[0061] Refer to Figures 1-8 , the first contact block 31 is slidably installed in one of the first connection grooves 18. A flipping mechanism is provided in the other first connection groove 18. The flipping mechanism passes through the other through opening 19 and extends into the other second connection groove 32. A top plate 20 is provided on the flipping mechanism. Through the flipping mechanism, the connection and fixation between the two lifting baffles 4 can be fully completed, so as to realize the synchronous lifting of multiple lifting baffles 4 and achieve the flood control effect.

[0062] Refer to Figures 1-8 , the flipping mechanism includes a connecting rod 23 provided in the other first connection groove 18. The connecting rod 23 passes through the other through opening 19 and extends into the other second connection groove 32. A second contact block 33 is slidably installed in the other second connection groove 32. The lower end of the connecting rod 23 is rotatably connected to a push rod 24. One end of the push rod 24 is rotatably connected to one side of the second contact block 33. A clamping mechanism is provided at the upper end of the second contact block 33; when the first contact block 31 is inserted into the other first connection groove 18, the first contact block 31 can be made to squeeze the connecting rod 23 to deflect, so that the connecting rod 23 pushes the push rod 24 to make the second contact block 33 inserted into one of the second connection grooves 32, and at the same time, the clamping mechanism can be inserted into the other inclined baffle member 2 to complete the connection and fixation of the two inclined baffle members 2.

[0063] Refer to Figures 1-8, the clamping mechanism includes a connecting rod 23 opened at the upper end of the second abutting block 33. A reset spring member 21 is fixed at the bottom inside the connecting rod 23, and the lower end of the top plate 20 is fixed at the upper end of the reset spring member 21. The reset spring member 21 pushes the top plate 20 to rise, enabling the top plate 20 and the inclined block 41 inside another inclined baffle member 2 to rise, so as to complete the connection and fixation of the two inclined baffle members 2.

[0064] Refer to Figures 1-8 , an inclined block 41 is installed inside one of the through openings 19, and the inclined block 41 abuts against the first abutting block 31. When the first abutting block 31 resets, it can cause the first abutting block 31 to squeeze the inclined block 41, so as to make the top plate 20 retract into the installation groove 22, facilitating the separation of the two inclined baffle members 2.

[0065] The present invention also proposes a flood control method for a flood control device used in water conservancy projects, including the following steps:

[0066] S1. Assembly of the water retaining dam: Arrange multiple inclined baffle members 2 in sequence, and the sealing member 17 on one lifting baffle 4 corresponds to the end without the sealing member 17 on another lifting baffle 4. The staff controls the rotation of the screw member 30 and the rotation direction of the screw member 30, so that the screw member 30 pushes the threaded sleeve 34 to descend. When the threaded sleeve 34 descends, it can push the first abutting block 31 to move towards the first connection groove 18 without the first abutting block 31 inside another lifting baffle 4 through the push rod 36. The first abutting block 31 can squeeze the connecting rod 23 inside another lifting baffle 4, causing the connecting rod 23 to push the push rod 24 and the second abutting block 33 to insert into the second connection groove 32 without the second abutting block 33 inside the original lifting baffle 4. Through the reset spring member 21 and the top plate 20, the top plate 20 can rise and insert into the second connection groove 32 without the second abutting block 33 in the original lifting baffle 4, and can insert into the corresponding through opening 19 to complete the connection of the two lifting baffles 4 and the connection of the two inclined baffle members 2. At the same time, during installation, a sealing gasket component can be added between adjacent two inclined baffle members 2 to complete the sealing between the two inclined baffle members 2;

[0067] S2. Sealing and anti-seepage: When the threaded sleeve 34 descends, it can drive the turntable member 28 and the two abutting shafts 29 through the cross shaft 35 to flip the swing rod 26, so as to push the moving plate 16 and the sealing member 17 towards another lifting baffle 4, causing the sealing member 17 to be squeezed to achieve a sealing effect;

[0068] S3. Basic flood control: When the water wave of the flood comes, the water wave impacts the inclined baffle member 2, causing the inclined baffle member 2 to flip towards the dam assembly 1. However, the inclined baffle member 2 is inclined and sealed through the rubber sealing member 3, enabling the water wave to flow back along the surface of the inclined baffle member 2. And when the water surface slowly rises, it will also cause the water to squeeze the inclined baffle member 2, causing the inclined baffle member 2 to rotate towards the dam assembly 1;

[0069] S4. Flood control when the flood intensifies: When the flood waves are large, the inclined baffle member 2 can push the swing member 12, causing the sliding block 11 to rise along the sliding groove 7. The vertical plate member 13 and the swing plate 9 at the upper end of the sliding block 11 can penetrate the insertion opening 6 and enter the insertion slot 5. The swing plate 9 is pushed to unfold by the resistance spring member 10, thereby fixing the position of the sliding block 11. The sliding block 11 can squeeze the pressure rod member 8, causing the turning rod 37 to rotate, thereby pulling the linkage plate 14 to rise. The lifting baffle 4 is pulled by a plurality of lifting wire winding wheel assemblies 38 on the linkage plate 14 through the pull rope 39, thereby driving the lifting baffle 4 to rise. The position height of the lifting baffle 4 can be limited, achieving the flood control effect.
