Description

Technical Field

[0001] This application relates to the technical field of anti-collision equipment for pumped storage power stations, and in particular to an anti-collision guardrail for pumped storage power stations. Background Technology

[0002] Pumped-storage hydroelectric power stations utilize electricity generated during periods of low electricity load to pump water into an upper reservoir, and then release the water into a lower reservoir to generate electricity during periods of high load. Also known as pumped-storage hydroelectric power stations, they can convert excess electricity generated during periods of low grid load into high-value electricity generated during periods of high load. They are also suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and serve as emergency backups. Furthermore, they can improve the efficiency of thermal and nuclear power plants within the system. Pumped-storage power stations are generally located near mountains, where falling rocks are frequent, making guardrails essential. However, current guardrail structures around pumped-storage power stations are relatively simple, primarily made of rigid materials, lacking good cushioning and offering poor impact resistance. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a crash barrier for pumped storage power stations to solve or partially solve the problems raised in the background art.

[0004] To achieve the above objectives, this application provides a crash barrier for a pumped storage power station, comprising:

[0005] The protective structure includes a mounting frame, a protective frame, and a supporting base plate. The supporting base plate is fixed to the lower part of the mounting frame, the upper part of the mounting frame and the upper part of the protective frame are spaced apart, and the bottom of the protective frame contacts the supporting base plate and can move along the supporting base plate.

[0006] At least two first buffer members are spaced apart. Each first buffer member includes a damper and an elastic member sleeved on the outer wall of the damper. One end of the damper is connected to the upper part of the mounting frame, and the other end of the damper is connected to the upper part of the protective frame.

[0007] Optionally, it also includes a plurality of second buffers. A plurality of guide rods are spaced apart in the mounting frame. Each guide rod has a second buffer sleeved on its outer wall. One end of the second buffer is connected to the upper part of the mounting frame, and the other end of the second buffer is connected to the lower part of the protective frame.

[0008] Optionally, the second buffer includes a tension spring and a tension member. The tension spring is sleeved on the outer wall of the guide rod. One end of the tension spring is connected to the upper part of the mounting frame, and the other end of the tension spring is connected to one end of the tension member. The other end of the tension member passes through the lower part of the mounting frame and is connected to the lower part of the protective frame.

[0009] Optionally, the tensioning member includes a slider and a pull rope. The slider is sleeved on the outer wall of the guide rod. One end of the slider is connected to the tension spring, and the other end of the slider is connected to one end of the pull rope. The other end of the pull rope passes through the lower part of the mounting frame and is connected to the lower part of the protective frame.

[0010] Optionally, the lower part of the mounting frame is provided with a plurality of guide holes, each of which corresponds to a plurality of second buffer components. The pull rope passes through the guide holes and is connected to the lower part of the protective frame.

[0011] Optionally, the mounting frame is further provided with a protective plate on the side near the protective frame, and the guide rod and the second buffer are both located on the side of the protective plate away from the protective frame.

[0012] Optionally, the mounting frame includes two side posts arranged opposite each other, and a plurality of guide rods are located between the two side posts. Two first buffers are provided, and the two first buffers are respectively connected to the two side posts.

[0013] Optionally, the upper part of the side column is provided with a first mounting seat, and the upper part of the protective frame is provided with a second mounting seat. The first mounting seat and the second mounting seat are arranged opposite to each other.

[0015] Optionally, the protective frame includes a protective frame and a protective element located within the protective frame, wherein the protective element is a grid-like structure.

[0016] As can be seen from the above, the anti-collision guardrail for pumped storage power stations provided in this application, through the combined design of dampers and springs, can effectively absorb and dissipate external impact forces, reducing the force directly transmitted to the fixed structure, thereby improving the overall buffering performance of the guardrail, reducing the probability of wear and damage to key components, and helping to extend the service life of the entire anti-collision guardrail. Furthermore, the combined design of dampers and springs can also change the angle of stone impact and intervene in its path, reducing the possibility of stones directly hitting important facilities and enhancing the safety around the pumped storage power station. The design of the load-bearing base plate and the lower end of the protective frame being relatively movable ensures that the protective frame can move stably along the predetermined direction when impacted, avoiding the breakage problem that may be caused by the traditional fixed hinge method, and improving the service life of the entire anti-collision guardrail.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0024] See Figure 1 , Figure 2 and Figure 3As shown, this application provides a crash barrier for a pumped storage power station, comprising: a protective structure 1, including a mounting frame 11, a protective frame 12, and a supporting base plate 13, wherein the supporting base plate 13 is fixed to the lower part of the mounting frame 11, the upper part of the mounting frame 11 and the upper part of the protective frame 12 are spaced apart, the bottom of the protective frame 12 contacts the supporting base plate 13 and can move along the supporting base plate 13; at least two first buffer members 2 are spaced apart, each first buffer member 2 including a damper 21 and an elastic member 22 sleeved on the outer wall of the damper 21, one end of the damper 21 is connected to the upper part of the mounting frame 11, and the other end of the damper 21 is connected to the upper part of the protective frame 12.

[0025] Specifically, the mounting frame 11 is a frame structure, which includes two side columns 111 arranged opposite to each other and two top columns 112 arranged opposite to each other. The two top columns 112 and the two side columns 111 together form the mounting frame 11.

[0026] The protective frame 12 is also a frame structure similar to the mounting frame 11.

[0027] The supporting base plate 13 is fixed to the lower part of the mounting frame 11. Two supporting base plates 13 are provided, spaced apart, and extend from the mounting frame 11 towards the protective frame 12. The supporting base plate 13 serves as the supporting structure for the entire crash barrier, improving the structural stability of the entire device.

[0028] The upper part of the mounting frame 11 and the upper part of the protective frame 12 are spaced apart, and the bottom of the protective frame 12 contacts the supporting base plate 13. Thus, the mounting frame 11, the supporting base plate 13, and the protective frame 12 together form a receiving space with an opening only at the top. In actual use, dangerous objects such as rocks from nearby forests can fall into this receiving space through the top opening, preventing falling rocks from injuring nearby people or facilities.

[0029] The bottom of the protective frame 12 can move along the supporting base plate 13. Thus, when a falling stone enters the receiving space and moves from the top to the bottom of the receiving space, the stone will provide an outward pushing force to the protective frame 12, causing the bottom of the protective frame 12 to move away from the mounting frame 11 along the supporting base plate 13. This creates a gap between the bottom of the protective frame 12 and the lower part of the mounting frame 11 to accommodate the falling stone.

[0030] The first buffer element 2 includes a damper 21 and an elastic element 22 sleeved on the outer wall of the damper 21. One end of the damper 21 is connected to the upper part of the mounting frame 11, and the other end of the damper 21 is connected to the upper part of the protective frame 12. The damper 21, also known as a shock absorber, is a device that provides resistance to motion and dissipates kinetic energy, thereby achieving the function of vibration reduction and energy dissipation. The elastic element 22 can be a spring, which is fixedly sleeved on the outer wall of the damper 21. In this way, the damper 21 and the elastic element 22 located at the upper part can buffer stones entering the receiving space.

[0031] In practice, when a stone enters the receiving space through the upper opening, the impact of the stone causes the protective frame 12 to open outward. The outward opening of the protective frame 12 will cause the damper 21 to stretch, and the stretching of the damper 21 will cause the elastic element 22 to stretch. In this way, the stretched damper 21 and elastic element 22 will buffer the instantaneous impact of the stone, and the damper 21 will consume the impact energy, reducing the impact force of the stone and changing the impact angle of the stone, thus reducing the possibility of the stone directly hitting important facilities.

[0032] As the falling stones move from the top to the bottom of the receiving space, they continue to exert an outward pushing force on the protective frame 12, causing the bottom of the protective frame 12 to move away from the mounting frame 11 along the supporting base plate 13. This creates a gap between the bottom of the protective frame 12 and the lower part of the mounting frame 11 to accommodate the falling stones. In this way, the falling stones will not have a significant impact on the bottom of the protective frame 12, nor will they cause damage to the entire crash barrier.

[0033] In this application, the combined design of damper 21 and spring effectively absorbs and dissipates external impact forces, reducing the force directly transmitted to the fixed structure, thereby improving the overall buffering performance of the guardrail, reducing the wear and damage probability of key components, and helping to extend the service life of the entire crash barrier. Furthermore, the combined design of damper 21 and spring can also change the angle of stone impact and intervene in its path, reducing the possibility of stones directly hitting important facilities and enhancing the safety around the pumped storage power station. The design of the load-bearing base plate 13 and the lower end of the protective frame 12 being able to move relative to each other ensures that the protective frame 12 can move stably along the predetermined direction when impacted, avoiding the breakage problem that may be caused by the traditional fixed hinge method, and improving the service life of the entire crash barrier.

[0034] In some embodiments, a plurality of second buffers 3 are also included. A plurality of guide rods 113 are spaced apart inside the mounting frame 11. Each guide rod 113 is fitted with a second buffer 3 on its outer wall. One end of the second buffer 3 is connected to the upper part of the mounting frame 11, and the other end of the second buffer 3 is connected to the lower part of the protective frame 12.

[0035] Specifically, the mounting frame 11 includes two top posts 112 arranged opposite each other. The top of the guide rod 113 is fixed to the inner wall of one of the top posts 112, and the bottom of the guide rod 113 is fixed to the other top post 112, thus achieving the fixation of the guide rod 113.

[0036] Each guide rod 113 is fitted with a second buffer 3 on its outer wall. One end of the second buffer 3 is connected to the upper part of the mounting frame 11, and the other end of the second buffer 3 is connected to the lower part of the protective frame 12. The second buffer 3 is connected to both the mounting frame 11 and the protective frame 12 to further buffer the stones falling into the receiving space.

[0037] In some embodiments, the second buffer 3 includes a tension spring 31 and a tension member 32. The tension spring 31 is sleeved on the outer wall of the guide rod 113. One end of the tension spring 31 is connected to the upper part of the mounting frame 11, and the other end of the tension spring 31 is connected to one end of the tension member 32. The other end of the tension member 32 passes through the lower part of the mounting frame 11 and is connected to the lower part of the protective frame 12.

[0038] Specifically, the tension member 32 includes a slider 321 and a pull rope 322. The slider 321 is sleeved on the outer wall of the guide rod 113. One end of the slider 321 is connected to the tension spring 31, and the other end of the slider 321 is connected to one end of the pull rope 322. The other end of the pull rope 322 passes through the lower part of the mounting frame 11 and is connected to the lower part of the protective frame 12.

[0039] Furthermore, the lower part of the mounting frame 11 is provided with a plurality of guide holes 114, and the plurality of guide holes 114 correspond one-to-one with the plurality of second buffer members 3. The pull rope 322 passes through the guide holes 114 and is connected to the lower part of the protective frame 12.

[0040] In the second buffer 3, the top of the tension spring 31 is connected to the upper part of the mounting frame 11, the bottom of the tension spring 31 is connected to the top of the slider 321, the bottom of the slider 321 is connected to one end of the pull rope 322, and the other end of the pull rope 322 passes through the guide hole 114 and is connected to the protective frame 12. Thus, when a stone falling into the receiving space moves from the top to the bottom of the receiving space, the stone will continue to provide an outward pushing force to the protective frame 12, causing the bottom of the protective frame 12 to move away from the mounting frame 11 along the bearing base plate 13. As the bottom of the protective frame 12 moves away from the mounting frame 11 along the supporting base plate 13, the bottom of the protective frame 12 will be stretched away from the mounting frame 11. The stretching movement will cause the slider 321 to slide downward along the guide rod 113. The downward sliding slider 321 will cause the tension spring 31 to be stretched downward. At the same time, the tension spring 31 will provide an opposite upward pulling force. Thus, the combined action of the stretching, the slider 321, and the tension spring 31 will further buffer the downward moving stone, further consume the impact energy of the stone, and convert the energy into the elastic potential energy stored in the stretched tension spring 31, thereby further achieving the buffering effect.

[0041] In practice, when a stone falls, it lands between the protective frame 12 and the mounting frame 11. The impact of the stone on the protective frame 12 causes it to open outwards. When the protective frame 12 opens, the upper damper 21 is stretched and the elastic element 22 is stretched, thus buffering the instantaneous impact of the stone. The damper 21 also dissipates the impact energy, causing the angle at which the stone impacts the protective frame 12 to change. As the stone continues to fall downwards, the impact causes the lower end of the protective frame 12 to move outwards on the supporting base plate 13. At the same time, the pull rope 322 pulls the slider 321 downwards on the guide rod 113, overcoming the tension of the tension spring 31. This further dissipates the impact energy of the stone during the movement, converting the energy into the elastic potential energy stored in the stretched tension spring 31, thus further achieving a buffering effect.

[0042] In this application, energy is not only absorbed by the damper 21 and the elastic element 22, but also by forming a two-stage energy absorption mechanism through the combination of the pull rope 322, the slider 321, the guide rod 113 and the tension spring 31, which further improves the energy absorption capacity of the crash barrier, thereby making the crash barrier have a good buffer function, strong anti-collision ability, not easy to be damaged, and long service life.

[0043] In some embodiments, the mounting frame 11 is further provided with a protective plate on the side near the protective frame 12, and the guide rod 113 and the second buffer 3 are both located on the side of the protective plate away from the protective frame 12. In this way, the protective plate can protect the mounting frame 11, the guide rod 113 and the second buffer 3, prevent falling stones from damaging these components and improve the service life of the entire crash barrier.

[0044] In some embodiments, the mounting frame 11 includes two side posts 111 arranged opposite to each other, and a plurality of guide rods 113 are located between the two side posts 111. Two first buffer members 2 are provided, and the two first buffer members 2 are respectively connected to the two side posts 111. In this way, the distance between the two first buffer members 2 is large, which makes it easier for stones to fall into the receiving space.

[0045] In some embodiments, the upper part of the side column 111 is provided with a first mounting seat 4, and the upper part of the protective frame 12 is provided with a second mounting seat 5. The first mounting seat 4 and the second mounting seat 5 are arranged opposite to each other. The first mounting seat 4 is connected to one end of the damper 21, and the second mounting seat 5 is connected to the other end of the damper 21. Thus, the arrangement of the first mounting seat 4 and the second mounting seat 5 improves the structural stability of the damper 21, ensuring that the damper 21 remains stable when impacted by falling stones and will not loosen or fall off.

[0046] In some embodiments, the protective frame 12 includes a protective frame 121 and a protective member 122 located within the protective frame 121. The protective member 122 is a mesh structure or a grid structure. Thus, the protective frame 121 ensures the rigidity and stability of the entire protective frame 12, while the mesh or grid structure of the protective member 122 can both prevent stones from falling out of the protective frame 12 and reduce the overall weight of the anti-slip frame.
