An installation groove is opened at the top of the fixed seat. The present invention solves the problems that during the use of existing water conservancy project dams, the structure of the dam is relatively fixed. And with the increase of the use time, in the case of being washed by water for a long time, it is very easy to corrode and fall off, resulting in the damage of the dam body structure and low stability, seriously affecting the safety of the dam and unable to meet the current use requirements. Moreover, the structures of some dam reinforcement and protection components are relatively fixed and cannot adjust the reinforcement and protection ability of the dam according to the water level. When the water pressure gradually increases, it is easy to cause damage to the reinforcement and protection components and the dam structure.

[0004] In the above technical solution, it cannot be adjusted sufficiently according to the water level situation, cannot fully correspond to the horizontal plane position to block the water waves, and in the case of large water waves, it cannot effectively block to avoid the water waves from attacking the dam body. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a reinforcement and protection component and a reinforcement method for a water conservancy project dam.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A reinforcement and protection component for a dam of a water conservancy project, including a dam body, a U-shaped frame is detachably connected to the dam body, a movable guard plate is installed on one side of the U-shaped frame, two telescopic components are slidably installed in the movable guard plate, a baffle is commonly installed on the two telescopic components, a buoyancy component is commonly installed at the lower ends of the two telescopic components, a moving component is installed in the telescopic component, the moving component is connected to the baffle, and a high-pressure airbag retraction component is commonly installed between the moving component and the telescopic component, and the high-pressure airbag retraction component is connected to the buoyancy component;

[0008] The movable guard plate is arranged parallel to the inclined surface of the dam body, and a V-shaped arrangement is formed between the baffle and the movable guard plate;

[0009] A blocking plate member and a swinging plate are arranged in the baffle, the swinging plate is rotatably connected to the side of the blocking plate member away from the dam body, and the swinging plate is connected to the moving component;

[0010] The movable guard plate includes an inclined plate member and two movable baffles, and the two movable baffles are respectively slidably installed at both ends of the side of the inclined plate member close to the dam body.

[0011] Compared with the prior art, the present application can make the upper end of the baffle located at the upper end of the water body through the buoyancy component and the high-pressure airbag retraction component under the buoyancy action in the water body, and can effectively break the continuous and uniform impact of the water wave by converting the impact force of the water wave. When the water wave becomes larger, it can quickly lock the position of the baffle and expand the two movable baffles to fully block the dam body to avoid the water wave directly impacting the dam body. Moreover, the U-shaped frame can effectively reinforce the dam body and improve the firmness of the dam body facing the water wave.

[0012] Preferably, sliding grooves are respectively opened at both ends of the side of the movable guard plate away from the dam body, the two telescopic components are respectively installed in the two sliding grooves, two openings are opened on the inclined plate member, the two movable baffles are respectively arranged on one side of the two openings, and two swinging rods are arranged in the moving component, and the two swinging rods respectively penetrate through the two openings and are rotatably connected to the two movable baffles.

[0013] Furthermore, the movable guard plate is inclined and connected to the U-shaped frame, which can fully ensure the installation stability. Moreover, when the water wave is large, the impact force of the water wave can be converted, so that the movable baffle can be fully expanded to cooperate with the inclined plate member to effectively block the dam body to avoid the water wave directly impacting the dam body. And the inclined setting is beneficial to deflect the impact force of the water wave to protect the movable guard plate and the dam body. At the same time, the arranged sliding grooves can facilitate the movement of the sliding frame to control the position of the baffle according to the water level situation.

[0014] Preferably, two sliding frames and two support frames are arranged inside the telescopic assembly. The support frame is connected to the high-pressure airbag retraction assembly. An installation groove is formed at the upper end of the support frame. The moving assembly is connected to the installation groove and the support frame. The two sliding frames are respectively slidably installed in the two sliding grooves. An extrusion mechanism is arranged inside the sliding frame. A linkage rod is arranged on the extrusion mechanism. A resistance mechanism is connected to the linkage rod. A support shaft is commonly arranged on the two resistance mechanisms. The two support frames are respectively fixed on the two sliding frames. The support shaft is slidably installed on the two support frames. The support shaft is fixedly connected to the blocking plate member.

[0015] Furthermore, the impact force of the water wave can be converted by the extrusion mechanism, enabling the extrusion mechanism to operate, so as to control the resistance mechanism to make the contact member cooperate with the sliding groove, and fully limit the position of the baffle.

[0016] Preferably, the extrusion mechanism includes a bearing groove formed in the sliding frame. Opposite side walls inside the bearing groove are both provided with contact ports. Contact members are slidably installed in the contact ports. Opposite ends of the two contact members are respectively rotatably connected to one end of a contact rod. One ends of the two contact rods are commonly rotatably connected to one end of the linkage rod.

[0017] Furthermore, when the baffle is impacted by the water wave and the resistance mechanism operates, the contact rod can be extruded, causing the angle between the two contact rods to become larger, separating and moving the two contact members. The outer side of the contact member abuts against the inner wall of the sliding groove, fully limiting the position of the sliding frame, and limiting the position height of the baffle through the sliding frame.

[0018] Preferably, the resistance mechanism includes an elastic resistance assembly fixed on the support frame. The support shaft penetrates through the piston rods of the two elastic resistance assemblies. Two ends of the support shaft are respectively slidably installed on the two support frames. Two linkage rods are respectively fixed on the piston rods of the elastic resistance assembly.

[0019] Furthermore, when the baffle is impacted by the water wave, the baffle will be extruded and move towards the direction of the moving guard plate, causing the baffle to drive the support shaft to move towards the direction of the moving guard plate, enabling the piston rod of the elastic resistance assembly to be extruded, so as to make the linkage rod move towards the direction of the moving guard plate, and control the operation of the extrusion mechanism.

[0020] Preferably, two connection ports are formed on the baffle. Push rod members penetrate through the two connection ports. Lower ends of the two push rod members are respectively connected to the two moving assemblies. Upper ends of the two push rod members are commonly rotatably connected to one side of the swing plate.

[0021] Furthermore, as the baffle is impacted by the water wave and moves towards the dam body, the lower end position of the push rod member remains stationary, and the blocking plate member moves towards the dam body, enabling the push rod member to push the swing plate to rotate towards the horizontal plane. When the water wave impacts and causes the blocking plate member to rise, it can deflect through the swing plate, causing the water body to fall back into the water wave to interrupt the uniform and continuous waveform impact of the water wave.

[0022] Preferably, the moving assembly includes a fixed frame, the fixed frame is connected to the high-pressure airbag retraction assembly, a reset mechanism is provided on the fixed frame, the reset mechanism is connected to the telescopic assembly, a through hole is formed in the telescopic assembly, a linkage shaft is rotatably sleeved in the through hole, an extrusion plate is fixed to the upper end of the linkage shaft, the extrusion plate abuts against the fixed frame, a rotating rod is fixed to the lower end of the linkage shaft, and the two rotating rods are respectively rotatably connected to the two swing rods.

[0023] Furthermore, after the position of the sliding frame is fixed due to the impact of the water wave and the water level rises simultaneously, the high-pressure airbag retraction assembly operates, enabling the reset mechanism to operate. After quickly making the extrusion plate flush with the inner wall of the installation groove, the rotating rod and the swing rod can push the moving baffle to move, which helps the moving baffle and the inclined plate member to form a shielding surface to fully protect the dam body.

[0024] Preferably, the reset mechanism includes an elastic telescopic rod fixed inside the telescopic assembly, and the elastic telescopic rod is fixedly connected to the fixed frame.

[0025] Furthermore, the elastic telescopic rod can enable the fixed frame to be quickly pushed, enabling the fixed frame to squeeze the extrusion plate to provide power for the deployment of the moving baffle.

[0026] Preferably, the high-pressure airbag retraction assembly includes a high-pressure airbag assembly fixed to the lower end of the buoyancy assembly, a sealing pipe fitting is fixed to one side of the telescopic assembly, a T-shaped insertion rod is slidably installed in the sealing pipe fitting, a spring member is jointly fixed on the T-shaped insertion rod and a section of the side wall inside the sealing pipe fitting, the T-shaped insertion rod is connected to the moving assembly, and the end of the sealing pipe fitting away from the spring member is connected to the high-pressure airbag assembly.

[0027] Furthermore, after the contact member abuts against the sliding groove, the position of the baffle is fixed. When the water level continues to rise, the water pressure squeezes the high-pressure airbag retraction assembly, enabling the high-pressure gas in the high-pressure airbag retraction assembly to enter the sealing pipe fitting, and enabling the T-shaped insertion rod to separate from the fixed frame. This can facilitate the movement of the fixed frame, that is, when the water level suddenly rises rapidly, the high-pressure airbag retraction assembly and the moving assembly can cooperate effectively to fully deploy the moving guard plate and effectively shield and protect the dam body.

[0028] The present invention also provides a reinforcement method for a reinforcement and protection component of a water conservancy project dam, which is applicable to the reinforcement and protection component of the water conservancy project dam mentioned above, and comprises the following steps:

[0029] S1. Component installation and reinforcement: The U-shaped frame is installed on the dam body to effectively reinforce the dam body, and the U-shaped frame and the dam body are fixedly connected by corresponding expansion bolts to improve the firmness of the dam body. The movable guard plate and the U-shaped frame are fixedly connected to effectively ensure the stability of the installation of the baffle, buoyancy assembly, high-pressure airbag retraction assembly and telescopic assembly;

[0030] S2. Buoyancy adjustment: The sliding frame is slidably installed in the sliding groove, which can make the buoyancy component and the high-pressure airbag retraction component enter the water body. Through the buoyancy of the high-pressure airbag retraction component and the buoyancy component, the lower end of the baffle can be located in the water body, and the upper end of the baffle can be located above the water body, so as to block the surface waves through the baffle to prevent the waves from directly invading the dam body;

[0031] S3. Preliminary water wave blocking: When the water surface waves hit the blocking plate, the blocking plate contracts by squeezing the elastic resistance component through the support shaft, and the elastic resistance component can push the linkage rod so that the two resistance rods push the two resistance components to squeeze the inner wall of the sliding groove, so that the height of the baffle position can be fixed. At the same time, due to the movement of the blocking plate, the push rod can push the swing plate to rotate. The water surface waves hit the lower end of the blocking plate and rise along the blocking plate, and flow back into the water body through the flipped swing plate, which can fully interrupt the continuity of the water surface ripples and help protect the blocking plate and the dam body;

[0032] S4. Closed shielding: When the ripples on the water surface gradually increase and the impact on the baffle increases, the baffle position is fixed through the resistance of the resistance piece and the sliding groove. However, as the water level rises, the squeezing force on the high-pressure airbag retraction assembly increases, which can cause the T-shaped plug-in rod to be pulled out from the support frame and the fixed frame, and the blocking plate member can cause the fixed frame to squeeze the extrusion plate through the push rod member. As the extrusion plate and the linkage shaft rotate, the rotating rod can push the swing rod to move the movable baffle, and the shielding range is expanded by the inclined plate member and the two movable baffles, effectively blocking the dam body and preventing water waves from impacting the dam body.

[0033] Compared with the prior art, the present application provides a detailed description of how to reinforce the dam body, how to block the impact of water waves and fully shield the dam body, so as to facilitate those skilled in the art to understand the operating principles of the components.

[0034] The beneficial effects of the present invention are:

[0035] 1. By converting the buoyancy and the impact force of water waves through the ingenious cooperation of multiple components, the position change of the components in this application can be controlled according to the changes in the water wave and the water level position, fully achieving the purpose of preventing the water wave from directly impacting the dam body. It can also disrupt the persistence and operational uniformity of the water wave, and can reinforce the dam body through the U-shaped frame.

[0036] 2. During actual production and preparation, the specifications of the buoyancy components can be designed based on the buoyancy required for components such as the telescopic component, the moving component, and the baffle to float when calculated, so as to enable the lower end of the baffle to be inserted into the water body to effectively block the water wave from directly impacting the dam body through the baffle.

[0037] 3. When the baffle member moves towards the dam body under the impact of the water wave, the swing plate and the baffle member can be separated under the action of the push rod member. The water wave impacts the lower end of the baffle member, causing the water body to rise along the baffle member, and the water body will impact the swing plate and flow back to impact the water wave, interrupting the persistence and uniformity of the water wave.

[0038] 4. At the same time, during use, when the impact of the water wave is large, the position height of the baffle is limited, and the water level rises rapidly, the gas in the high-pressure airbag retraction component can be squeezed, causing the T-shaped insertion rod member to separate from the fixed frame. In this way, the fixed frame can quickly squeeze the extrusion plate, facilitating the rapid deployment of the moving baffle. Cooperating with the baffle row layer double-blocking protection structure, it can prevent the water wave from directly impacting the dam body. Moreover, when the water wave fluctuates, it can be effectively reduced through the baffle and the moving protection plate. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0048] 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.

[0049] Refer to Figure 1-8 , a reinforcement and protection component for a water conservancy project dam, including a dam body 1. The dam body 1 can be prepared by a reinforced concrete structure, and at the same time, the side in contact with the water wave can be evenly paved with stones, and this side is inclined. A U-shaped frame 2 is detachably connected to the dam body 1. By setting and installing the U-shaped frame 2, the overall firmness can be fully improved to avoid loosening. A movable guard plate 3 is installed on one side of the U-shaped frame 2. There is a certain gap between the movable guard plate 3 and the dam body 1, which is convenient for subsequent inspection and maintenance.

[0050] Refer to Figure 1 , two telescopic assemblies 5 are slidably installed in the movable guard plate 3. A baffle 4 is commonly installed on the two telescopic assemblies 5. A buoyancy assembly 6 is commonly installed at the lower ends of the two telescopic assemblies 5. A moving assembly 7 is installed in the telescopic assembly 5. The moving assembly 7 is connected to the baffle 4. A high-pressure airbag retraction assembly 8 is commonly installed between the moving assembly 7 and the telescopic assembly 5. The high-pressure airbag retraction assembly 8 is connected to the buoyancy assembly 6; the specifications of the buoyancy assembly 6 can be designed according to the calculated buoyancy required for floating components such as the telescopic assembly 5, the moving assembly 7, and the baffle 4, so as to enable the lower end of the baffle 4 to be inserted into the water body, so as to effectively block the water wave from directly impacting the dam body 1 through the baffle 4.

[0051] Refer to Figure 1, the movable guard plate 3 is arranged parallel to the inclined surface of the dam body 1, and the baffle plate 4 and the movable guard plate 3 are arranged in a V shape. During actual production and preparation, there is a certain distance between the dam body 1 and the movable guard plate 3 for easy maintenance. At the same time, due to the V-shaped arrangement of the baffle plate 4 and the movable guard plate 3, the setting of the baffle plate 4 can facilitate the situation where the water body turns and impacts, effectively destroying the continuous fluctuation of the water wave.

[0052] Refer to Figure 1 、 5 , a blocking plate member 41 and a swing plate 43 are arranged inside the baffle plate 4. The swing plate 43 is rotatably connected to the side of the blocking plate member 41 away from the dam body 1, and the swing plate 43 is connected to the moving assembly 7. During actual preparation, the swing plate 43 can be pushed by the action of the push rod member 44 to deflect the swing plate 43 and the blocking plate member 41, so that the water wave impacts the blocking plate member 41 and the swing plate 43, causing the water wave to turn over and fall onto the water wave, destroying the uniformity and continuity of the water wave ripple.

[0053] Refer to Figure 1 、 2 、4, the movable guard plate 3 includes an inclined plate member 31 and two movable baffle plates 33. The two movable baffle plates 33 are respectively slidably installed at both ends of the inclined plate member 31 on the side close to the dam body 1. The two sliding frames 59 can respectively slide in the two sliding grooves 34. By controlling the action of the high-pressure airbag retraction assembly 8 and the buoyancy assembly 6, the baffle plate 4 can penetrate the water surface, effectively blocking the water surface ripple and fully protecting the dam body 1.

[0054] Refer to Figure 1 、 2 、4、7, sliding grooves 34 are respectively opened at both ends of the side of the movable guard plate 3 away from the dam body 1. The two telescopic assemblies 5 are respectively installed in the two sliding grooves 34. Two openings 32 are opened on the inclined plate member 31. The two movable baffle plates 33 are respectively arranged on one side of the two openings 32. Two swing rods 71 are arranged inside the moving assembly 7. The two swing rods 71 respectively penetrate the two openings 32 and are rotatably connected to the two movable baffle plates 33; the movable guard plate 3 is inclined and connected to the U-shaped frame 2, which can fully ensure the installation stability. Moreover, when the water wave is large, the impact force of the water wave can be converted, so that the movable baffle plate 3 can be fully unfolded to cooperate with the inclined plate member 31 to effectively block the dam body 1 and prevent the water wave from directly impacting the dam body 1. Moreover, the inclined setting is beneficial to deflect the impact force of the water wave to protect the movable guard plate 3 and the dam body 1. At the same time, the arranged sliding grooves 34 can facilitate the movement of the sliding frame 59 to control the position of the baffle plate 4 according to the water level situation.

[0055] Refer to Figure 1 、 2, 6, 7, two sliding frames 59 and two supporting frames 52 are arranged in the telescopic component 5, the supporting frames 52 are connected to the high-pressure airbag retraction component 8, the upper end of the supporting frame 52 is provided with a mounting groove 53, the moving component 7 is connected to the mounting groove 53 and the supporting frame 52, the two sliding frames 59 are respectively slidably installed in the two sliding grooves 34, a squeezing mechanism is arranged in the sliding frame 59, a linkage rod 54 is arranged on the squeezing mechanism, a resistance mechanism is connected to the linkage rod 54, a support shaft 510 is commonly arranged on the two resistance mechanisms, the two supporting frames 52 are respectively fixed on the two sliding frames 59, the support shaft 510 is slidably installed on the two supporting frames 52, and the support shaft 510 is fixedly connected to the blocking plate 41; the impact force of the water waves can be converted by the squeezing mechanism, the squeezing mechanism can be operated, so as to control the resistance mechanism to make the resistance member 55 and the sliding groove 34 cooperate, and fully limit the position of the baffle 4.

[0056] Reference Figure 1 , 2 , 6, 7, the extrusion mechanism includes a bearing groove 58 provided on the sliding frame 59, and the opposite side walls in the bearing groove 58 are provided with a resistance opening 57, and a resistance member 55 is slidably installed in the resistance opening 57, and the opposite ends of the two resistance members 55 are rotatably connected with a resistance rod 56, and one end of the two resistance rods 56 rotates together on one end of the linkage rod 54; when the baffle 4 is impacted by the wave and the resistance mechanism operates, the resistance rod 56 can be squeezed, so that the angle between the two resistance rods 56 becomes larger, and the two resistance members 55 are separated and moved, and the outer side of the resistance member 55 is in resistance with the inner wall of the sliding groove 34, which can fully define the position of the sliding frame 59, and the position height of the baffle 4 is defined by the sliding frame 59.

[0058] Reference Figure 1 , 5, two connection ports 42 are formed on the baffle 4, and push rod members 44 penetrate through both of the two connection ports 42. The lower ends of the two push rod members 44 are respectively connected to the two moving components 7, and the upper ends of the two push rod members 44 are jointly rotatably connected to one side of the swing plate 43. As the baffle 4 is impacted by the water wave and moves towards the direction of the dam body 1, the lower end positions of the push rod members 44 remain stationary, and the baffle plate member 41 moves towards the direction of the dam body 1, which can cause the push rod members 44 to push the swing plate 43 to rotate towards the horizontal plane. When the water wave impacts and the baffle plate member 41 rises, it can deflect through the swing plate 43, causing the water body to fall back into the water wave to interrupt the uniform and continuous waveform impact of the water wave.

After quickly making the extrusion plate 73 flush with the inner wall of the installation groove 53, the rotating rod 72 and the swing rod 71 can push the moving baffle 33 to move, which helps the moving baffle 33 and the inclined plate member 31 to form a shielding surface to fully protect the dam body 1.

[0060] Refer to Figure 1 , 2 , 3, 7, the reset mechanism includes an elastic telescopic rod 75 fixed in the telescopic component 5. The elastic telescopic rod 75 is fixedly connected to the fixed frame 76. Through the action of the elastic telescopic rod 75, the fixed frame 76 can be quickly pushed, and the fixed frame 76 can squeeze the extrusion plate 73 to provide power for the deployment of the moving baffle 33.

Preliminary water wave blocking: When the water surface waves hit the blocking plate 41, the blocking plate 41 squeezes the elastic resistance component 51 through the support shaft 510 to shrink, and the elastic resistance component 51 can push the linkage rod 54 so that the two abutting rods 56 push the two abutting components 55 to squeeze the inner wall of the sliding groove 34, so that the position height of the baffle 4 can be fixed. At the same time, due to the movement of the blocking plate 41, the push rod 44 can push the swing plate 43 to rotate. The water surface waves hit the lower end of the blocking plate 41 and rise along the blocking plate 41. The water surface waves flow back into the water body through the flipped swing plate 43, which can fully interrupt the continuity of the water surface ripples, which is helpful to protect the blocking plate 41 and the dam body 1;

[0066] S4. Closed occlusion: When the water surface ripples gradually increase and the impact on the baffle 4 increases, through the contact of the contact member 55 and the sliding groove 34, the position of the baffle 4 is fixed. However, as the water level rises, the extrusion force on the high-pressure airbag retraction assembly 8 increases, enabling the T-shaped insertion rod member 83 to be pulled out from the support frame 52 and the fixed frame 76, and enabling the blocking plate member 41 to cause the fixed frame 76 to squeeze the extrusion plate 73 through the push rod member 44. As the extrusion plate 73 and the linkage shaft 77 rotate, the rotating rod 72 can push the swing rod 71 to move the movable baffle 33, and the occlusion range is enlarged through the inclined plate member 31 and the two movable baffles 33, effectively blocking the dam body 1 and preventing the water wave from impacting the dam body 1.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

Component installation and reinforcement: The U-shaped frame (2) is installed through the dam body (1), so as to effectively reinforce the dam body (1), and the U-shaped frame (2) and the dam body (1) are fixedly connected by corresponding expansion bolts, so as to improve the firmness of the dam body (1), and the movable guard plate (3) and the U-shaped frame (2) are fixedly connected to effectively ensure the stability of the installation of the baffle (4), the buoyancy component (6), the high-pressure airbag retraction component (8) and the telescopic component (5); S2, buoyancy adjustment: the sliding frame (59) is slidably installed in the sliding groove (34), so that the buoyancy assembly (6) and the high-pressure airbag retraction assembly (8) can enter the water body. Through the buoyancy of the high-pressure airbag retraction assembly (8) and the buoyancy assembly (6), the lower end of the baffle (4) can be located in the water body, and the upper end of the baffle (4) can be located above the water body, so that the baffle (4) blocks the water surface waves, thereby preventing the waves from directly invading the dam body (1); S3, preliminary water wave blocking: when the water surface waves impact the blocking plate (41), the blocking plate (41) contracts by squeezing the elastic resistance component (51) through the support shaft (510), and the elastic resistance component (51) can push the linkage rod (54) so ​​that the two abutting rods (56) push the two abutting components (55) to squeeze the inner wall of the sliding groove (34), so that the height of the baffle plate (4) can be fixed.
