Description

Technical Field

[0001] The utility model relates to the technical field of dam body protection, in particular to a Yellow River dam body protection structure. Background Art

[0002] The Yellow River dam is a large-scale engineering structure built on the Yellow River for purposes such as flood control, power generation, and irrigation. As the second longest river in China, the Yellow River flows through many provinces. The geological, climatic and other conditions in its basin are complex. Therefore, the types and designs of the Yellow River dams are also varied and adapted to local conditions. Among them, the Yellow River bank embankment is a type of Yellow River dam.

[0003] Among natural factors, the water in the Yellow River continuously impacts the bank embankments, especially in areas with fast flow and rapid currents, which will cause the soil and stones on the surface of the bank embankments to be washed away, making the bank embankments gradually thinner and weaker. Long-term scouring may also cause structural problems such as cracks and collapse in the bank embankments.

[0004] In the prior art, a foot guard is set at the foot of the dam on the bank of the Yellow River, and materials such as stones and concrete blocks are used to protect the dam foot to prevent it from being washed away and eroded by the water flow. However, as time goes by and the river water washes away the stones and concrete blocks, problems such as displacement and breakage may occur, resulting in reduced protective effects. In order to maintain the protective effects, regular inspections and replenishments are required, which increases the cost of subsequent maintenance.

[0005] Therefore, a Yellow River dam protection structure is proposed to address the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model proposes a Yellow River dam body protection structure.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a Yellow River dam protection structure, comprising a dam body; a plurality of wave-breaking plates are installed on the dam body; a protective device is installed on the wave-breaking plates; the protective device comprises a sliding plate; two sliding blocks are installed at the bottom of the sliding plate; the sliding block is slidably connected to a fixed rod; a damper is connected to the bottom of the sliding block; a fixed block is fixedly connected to the bottom of the damper; the fixed block is fixed to the inner wall of the fixed rod; the damper is fixed to the inside of the fixed rod through the bottom fixed block; a fixing assembly is installed in the fixed rod; the fixing assembly comprises an extrusion rod.

[0008] Preferably, two extrusion rods are provided; the two extrusion rods are slidably connected to the same fixed block; a connecting plate is fixedly connected to the bottom of the two extrusion rods; an extrusion cone is installed at the bottom of the connecting plate; and the extrusion cone is slidably connected to the bottom of the fixed rod.

[0009] Preferably, the fixed rod is provided with six rotation grooves; a connecting shaft is installed in the rotation groove; six connecting rods are rotatably connected to the connecting shaft; a fixed plug rod is fixedly connected to the bottom of the connecting rod; and a protrusion is raised on the connection between the connecting rod and the fixed plug rod.

[0010] Preferably, six clamping grooves are provided on the extrusion cone; and the extrusion cone is arranged at the bottom of the fixing rod.

[0011] Preferably, eight plug-in rods are installed at the bottom of the wave-breaking board; the eight plug-in rods are arranged on both sides of the bottom of the wave-breaking board.

[0012] Preferably, the wave-breaking board is provided with two groups of water outlet grooves; each group of water outlet grooves is provided with four; and the two groups of water outlet grooves are provided on both sides of the wave-breaking board.

[0013] Preferably, the sliding plate is slidably connected to the wave-breaking board; and a plurality of railings are installed on the sliding plate.

[0014] The utility model is beneficial in that:

[0015] 1. The Yellow River dam protection structure described in the utility model has a protective device. When the structure is in operation, the impact wave generated by the river water impacts the sliding plate on the wave-breaking board, and the sliding plate slides on the fixed rod through the sliding block connected to the bottom. The damper connected to the bottom of the sliding block can effectively disperse and reduce the direct impact force of the river water impact wave on the dam body. When the impact wave impacts the sliding plate on the wave-breaking board, the sliding plate can slide on the fixed rod to disperse the impact force. At the same time, the damper connected to the bottom of the sliding block can further reduce the impact force to prevent it from causing serious damage to the dam body.

[0016] 2. The Yellow River dam body protection structure described in the utility model is provided with a fixed component. When working, the impact wave generated by the river water impacts the sliding plate, and the sliding plate drives the sliding block to hit the extrusion rod. The extrusion rod slides on the fixed block. The sliding extrusion rod drives the extrusion cone to slide at the bottom of the fixed rod through the connecting plate to squeeze the six connecting rods overlapped by the extrusion cone. The connecting rod drives the fixed plug rod to spread around in an umbrella shape, so that the fixed plug rod is inserted into the dam body. The fixed plug rod adaptively adjusts the insertion depth of the dam body according to the intensity of the impact wave. When the intensity of the impact wave increases, the extrusion force of the extrusion cone on the connecting rod also increases, causing the fixed plug rod to be inserted deeper into the dam body. This adaptive mechanism ensures that the protection structure can provide stable protection effect under impacts of different intensities. The depth of the fixed plug rod inserted into the dam body is proportional to the intensity of the impact wave. The protection structure can maintain a high-efficiency protection effect for a long time. Even after multiple impacts, the fixed plug rod can still be firmly fixed in the dam body, ensuring the durability of the protection structure. BRIEF DESCRIPTION OF THE DRAWINGS

The damper 303 connected to the bottom of the sliding block 302 can effectively disperse and reduce the direct impact force of the river water impact wave on the dam body 1. When the impact wave impacts the sliding plate 301 on the wave-breaking board 2, the sliding plate 301 can slide on the fixing rod 305, thereby dispersing the impact force. At the same time, the damper 303 connected to the bottom of the sliding block 302 can further reduce the impact force to prevent it from causing serious damage to the dam body 1.

[0027] Further, such as Figure 4 and Figure 5 As shown, two extrusion rods 3061 are provided; the two extrusion rods 3061 are slidably connected to the same fixed block 304; the bottom of the two extrusion rods 3061 is fixedly connected with a connecting plate 3062; the bottom of the connecting plate 3062 is installed with an extrusion cone 3063; the extrusion cone 3063 is slidably connected to the bottom of the fixed rod 305; by setting the fixed component 306, when working, the impact wave generated by the river water impacts the sliding plate 301, the sliding plate 301 drives the sliding block 302 to hit the extrusion rod 3061, the extrusion rod 3061 slides on the fixed block 304, and the sliding extrusion rod 3061 drives the extrusion cone 3063 to slide at the bottom of the fixed rod 305 through the connecting plate 3062, so as to perform extrusion and the extrusion cone 3063. The six connecting rods 4 are connected, and the connecting rods 4 drive the fixed plug rods 8 to spread out in an umbrella shape, so that the fixed plug rods 8 are inserted into the dam body 1. The fixed plug rods 8 adaptively adjust the insertion depth of the dam body 1 according to the strength of the impact wave.

[0029] Further, such as Figure 5 As shown, six snap-in grooves 3064 are provided on the extrusion cone 3063; the extrusion cone 3063 is arranged at the bottom of the fixed rod 305; when working, the river water impacts the sliding plate 301, and the sliding plate 301 drives the sliding block 302 to hit the extrusion rod 3061 and then squeeze the connecting rod 4. When the extrusion cone 3063 connected to the bottom of the extrusion rod 3061 is squeezed to a certain extent, the protrusion between the connecting rod 4 and the fixed plug rod 8 will be snapped into the snap-in groove 3064, thereby fixing the fixed plug rod 8 and the fixed assembly 306, so that the fixed plug rod 8 is firmly inserted into the inside of the dam body 1. By firmly fixing the plug rod 8, the protective structure of the dam body 1 can better play its protective role and reduce the erosion and damage of the river water to the dam body 1.

[0030] Further, such as Figure 2 As shown, eight plug-in rods 5 are installed at the bottom of the wave-breaking board 2; the eight plug-in rods 5 are arranged on both sides of the bottom of the wave-breaking board 2; by arranging the plug-in rods 5, when working, by inserting the plug-in rods 5 at the bottom of the wave-breaking board 2 into the dam body 1, by inserting the plug-in rods 5 at the bottom of the wave-breaking board 2 into the dam body 1, the connection firmness between the protective structure and the dam body 1 can be significantly enhanced, so that the protective structure is more stable when impacted by river water, and is not easy to be displaced or shaken, thereby effectively protecting the dam body 1 from damage.

When the impact wave impacts the sliding plate 301 on the wave-breaking board 2, the sliding plate 301 can slide on the fixed rod 305 to disperse the impact force. At the same time, the damper 303 connected at the bottom of the sliding block 302 can further reduce the impact force to prevent it from causing serious damage to the dam body 1.

The fixed plug rod 8 adaptively adjusts the insertion depth of the dam body 1 according to the strength of the impact wave. When the strength of the impact wave increases, the extrusion force of the extrusion cone 3063 on the connecting rod 4 also increases, causing the fixed plug rod 8 to be inserted deeper into the dam body 1. This adaptive mechanism ensures that the protective structure is not The present invention can provide a stable protection effect under the impact of the same intensity. The depth of the fixed plug rod 8 inserted into the dam body 1 is proportional to the intensity of the impact wave.
