When the water pressure gradually increases, it is easy to cause damage to the reinforcement and protection components and the dam structure.

[0003] The invention discloses a reinforcement and protection component and reinforcement method for a water conservancy project dam, with publication number CN115821846B, which comprises a dam body, wherein the upper and lower sides of one side of the dam body are provided with protection plates, a group of hollow protection plates are respectively embedded in the mounting grooves at both ends of the dam body, a fixing seat is provided at the bottom of the other side of the dam body, and a mounting groove is provided on the top of the fixing seat. The invention solves the problem that the structure of the existing water conservancy project dam is relatively fixed during use, and as the use time increases, it is easy to corrode and fall off when it is washed by water for a long time, resulting in damage to the dam structure, low stability, serious impact on the safety of the dam, and inability to meet the current use requirements, and the structure of some dam reinforcement and protection components is relatively fixed, and the reinforcement and protection ability of the dam cannot be adjusted 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] The above technical solution cannot be adjusted fully according to the water level and cannot fully correspond to the horizontal plane position to block the waves. Moreover, when the waves are large, it cannot be effectively blocked to prevent the waves from invading the dam body, so improvement is needed. Summary of the invention

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

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A reinforcement and protection component for a dam of a water conservancy project comprises 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, 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; The movable guard plate and the inclined surface of the dam body are arranged in parallel, and the baffle plate and the movable guard plate are arranged in a V shape; The baffle plate is provided with a blocking plate and a swing plate, the swing plate is rotatably connected to a side of the blocking plate away from the dam body, and the swing plate is connected to the moving assembly; The movable guard plate comprises an inclined plate member and two movable baffles, and the two movable baffles are respectively slidably mounted on two ends of the inclined plate member close to a side of the dam body.

[0007] Compared with the prior art, the present application can position the upper end of the baffle at the upper end of the water body through the buoyancy of the buoyancy component and the high-pressure airbag retraction component in the water body, and can effectively break the continuous and uniform impact of the waves by converting the impact force of the waves. It can also quickly lock the position of the baffle and deploy the two movable baffles when the waves become larger, so as to fully shield the dam body and prevent the waves from directly impacting the dam body. The U-shaped frame can effectively reinforce the dam body and improve the firmness of the dam body facing the waves.

[0008] Preferably, sliding grooves are provided at both ends of the side of the movable guard plate away from the dam body, and the two telescopic components are respectively installed in the two sliding grooves. Two openings are provided on the inclined plate, and the two movable baffles are respectively arranged on one side of the two openings. Two swing rods are provided in the movable component, and the two swing rods respectively pass through the two openings and are rotatably connected to the two movable baffles.

[0009] Furthermore, the movable guard plate is arranged at an angle and connected to the U-shaped frame, which can fully ensure the stability of the installation. When the waves are large, the impact force of the waves can be converted so that the movable baffle can be fully deployed to cooperate with the inclined plate to effectively shield the dam body and prevent the waves from directly impacting the dam body. The inclined arrangement is conducive to deflecting the impact force of the waves and protecting the movable guard plate and the dam body. At the same time, the sliding groove can facilitate the movement of the sliding frame so as to control the position of the baffle according to the water level conditions.

[0010] Preferably, the telescopic assembly is provided with two sliding frames and two supporting frames, the supporting frames are connected to the high-pressure airbag retraction assembly, the upper end of the supporting frame is provided with a mounting groove, the moving assembly is connected to the mounting groove and the supporting frame, the two sliding frames are slidably installed in the two sliding grooves respectively, the sliding frame is provided with an extrusion mechanism, the extrusion mechanism is provided with a linkage rod, the linkage rod is connected to a resistance mechanism, the two resistance mechanisms are jointly provided with a support shaft, the two supporting frames are respectively fixed on the two sliding frames, the support shaft is slidably installed on the two supporting frames, and the support shaft is fixedly connected to the blocking plate.

[0011] Furthermore, the impact force of the water waves can be transformed through the squeezing mechanism, which can enable the squeezing mechanism to operate, so as to control the resistance mechanism to make the resistance member and the sliding groove cooperate, thereby fully limiting the position of the baffle.

[0012] Preferably, the extrusion mechanism includes a bearing groove opened on the sliding frame, and the opposite side walls in the bearing groove are provided with interference openings, and interference parts are slidably installed in the interference openings. The opposite ends of the two interference parts are rotatably connected to interference rods, and one end of the two interference rods rotates together on one end of the linkage rod.

[0013] Furthermore, when the baffle is impacted by the waves and the resistance mechanism is activated, the resistance rod can be squeezed, so that the angle between the two resistance rods becomes larger, and the two resistance parts move apart. The outer side of the resistance part and the inner wall of the sliding groove are in contact, which can fully limit the position of the sliding frame, and the position height of the baffle is limited by the sliding frame.

[0014] Preferably, the resistance mechanism includes an elastic resistance component fixed on a support frame, the support shaft is arranged on the piston rods of the two elastic resistance components, the two ends of the support shaft are respectively slidably installed on the two support frames, and the two linkage rods are respectively fixed on the piston rods of the elastic resistance components.

[0015] Furthermore, when the baffle is impacted by water waves, the baffle will be squeezed and moved in the direction of the movable guard plate, which can drive the supporting shaft to move in the direction of the movable guard plate, and can squeeze the piston rod of the elastic resistance assembly so as to move the linkage rod in the direction of the movable guard plate, so as to control the operation of the squeezing mechanism.

[0016] Preferably, the baffle is provided with two connection ports, and push rods are provided through the two connection ports. The lower ends of the two push rods are respectively connected to the two moving components, and the upper ends of the two push rods are rotatably connected to one side of the swing plate.

[0017] Furthermore, as the baffle is moved toward the dam body by the impact of the waves, the lower end of the push rod member remains stationary, and the blocking plate member moves toward the dam body, which enables the push rod member to push the swing plate to rotate toward the horizontal plane. When the blocking plate member rises due to the impact of the waves, it can be deflected through the swing plate, causing the water body to fall back into the waves, thereby interrupting the uniform and continuous waveform impact of the waves.

[0018] Preferably, the moving assembly includes a fixed frame, which is connected to the high-pressure airbag retraction assembly. The fixed frame is provided with a reset mechanism, which is connected to the telescopic assembly. The telescopic assembly is provided with a through hole, and a linkage shaft is rotatably sleeved in the through hole. An extrusion plate is fixed to the upper end of the linkage shaft, and the extrusion plate is in conflict with the fixed frame. A rotating rod is fixed to the lower end of the linkage shaft, and the two rotating rods are rotatably connected to the two swing rods respectively.

[0019] Furthermore, when the impact of water waves fixes the position of the sliding frame and the horizontal plane rises, the high-pressure airbag retraction assembly operates, which can enable the reset mechanism to operate, quickly making the extrusion plate and the inner wall of the installation groove flush, and then the rotating rod and the swing rod can push the movable baffle to move, which helps the movable baffle and the inclined plate to form a shielding surface, thereby fully protecting the dam body.

[0020] Preferably, the resetting mechanism comprises an elastic telescopic rod fixed in the telescopic assembly, and the elastic telescopic rod is fixedly connected to a fixing frame.

[0021] Furthermore, the fixing frame can be pushed quickly by the elastic telescopic rod, so that the fixing frame can squeeze the squeezing plate to provide power for the expansion of the movable baffle.

[0022] Preferably, the high-pressure airbag retraction assembly includes a high-pressure airbag assembly fixed at the lower end of the buoyancy assembly, a sealing tube is fixed on one side of the telescopic assembly, a T-shaped plug rod is slidably installed in the sealing tube, a spring member is commonly fixed on the T-shaped plug rod and a section of the side wall in the sealing tube, the T-shaped plug rod is connected to the moving assembly, and the end of the sealing tube away from the spring member is connected to the high-pressure airbag assembly.

[0023] Furthermore, when the abutment member and the sliding groove abut against each other, the position of the baffle is fixed. When the water level continues to rise, the water pressure squeezes the high-pressure airbag retraction assembly, allowing the high-pressure gas in the high-pressure airbag retraction assembly to enter the sealing pipe fitting, thereby separating the T-shaped plug-in rod and the fixed frame. This facilitates the movement of the fixed frame, that is, when the water level rises suddenly and rapidly, the high-pressure airbag retraction assembly and the moving assembly can be effectively coordinated to fully deploy the moving guard plate, thereby effectively shielding and protecting the dam body.

[0024] 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: 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; 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; 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; 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.

[0025] 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.

[0026] The beneficial effects of the present invention are: 1. By transforming the buoyancy and the impact force of the waves through the ingenious cooperation of multiple components, the position change of the components in the present application can be controlled according to the changes in the position of the waves and the horizontal plane, so as to fully prevent the waves from directly impacting the dam body, disrupt the continuity of the waves and the uniformity of the operation, and reinforce the dam body through the U-shaped frame; 2. In actual production and preparation, the specifications of the buoyancy components can be designed according to the buoyancy required for the telescopic components, mobile components and baffles to float, so that the lower end of the baffle can be inserted into the water body to effectively block the waves from directly impacting the dam body through the baffle; 3. When the blocking plate moves toward the dam body under the impact of water waves, the swing plate and the blocking plate can be separated under the action of the push rod, and the water waves impact the lower end of the blocking plate, causing the water body to rise along the blocking plate, and the water body will impact the swing plate to flow back and impact the water waves, so that the continuity and uniformity of the water waves are interrupted; 4. At the same time, when in use, the impact of water waves is large, the position height of the baffle is limited, and the water level rises rapidly, which can squeeze the gas in the high-pressure airbag retraction assembly, so that the T-shaped plug-in rod and the fixed frame are separated, so that the fixed frame can quickly squeeze the extrusion plate, which is convenient for quickly deploying the mobile baffle. The double blocking protection structure of the baffle layer can prevent water waves from directly impacting the dam body, and when the water waves fluctuate, they can be effectively reduced by the baffle and the movable guard plate.

[0042] 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 is characterized in that it comprises the following steps: S1. Component installation and reinforcement: The U-shaped frame 2 is installed on the dam body 1 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 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 as to block the surface waves through the baffle 4 to prevent the waves from directly invading the dam body 1; S3.

10. A method for reinforcing a reinforcement and protection component of a water conservancy project dam, applicable to a reinforcement and protection component of a water conservancy project dam according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. 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. At the same time, due to the movement of the blocking plate (41), the push rod component (44) can push the swing plate (43) to rotate. The water surface waves impact the lower end of the blocking plate (41) and rise along the blocking plate (41), and flow back into the water body through the flipped swing plate (43), which can fully interrupt the continuity of the water surface ripples, thereby helping to protect the blocking plate (41) and the dam body (1); S4, closed shielding: When the ripples on the water surface gradually increase and the impact on the baffle (4) increases, the baffle (4) is fixed in position through the abutment member (55) and the sliding groove (34). However, as the water level rises, the squeezing force on the high-pressure airbag retraction assembly (8) increases, which can cause the T-shaped plug-in rod member (83) to be withdrawn from the support frame (52) and the fixing frame (76). The blocking plate member (41) can cause the fixing frame (76) to squeeze the squeezing plate (73) through the push rod member (44). As the squeezing plate (73) and the linkage shaft (77) rotate, the rotating rod (72) can push the swing rod (71) to move the movable baffle (33). The obstruction range is expanded through the inclined plate member (31) and the two movable baffles (33), and the dam body (1) is effectively blocked to prevent water waves from impacting the dam body (1).
