Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to an anti-erosion reservoir spillway side channel type spillway. Background Technology

[0002] With the development of science and technology and the progress of society, the construction of new reservoirs is gradually shifting to remote mountainous areas. Due to the geographical limitations of steep river valleys and slopes in mountainous areas, newly built reservoirs generally face practical problems such as high dam height but small reservoir capacity and large-scale spillway excavation, posing challenges to the project construction. However, side-channel spillways are more adaptable to terrain and geological conditions, and can more easily meet the construction needs of mountainous reservoirs, showing significant application advantages in such scenarios.

[0003] Traditional side-channel spillways face significant scouring problems during long-term flood discharge. Floodwaters possess considerable kinetic energy, continuously impacting and abrading the inner walls, bottom walls, and inlet area of ​​the side channel. This not only damages the main structure and shortens its lifespan but also can cause deformation and leakage, posing safety hazards and affecting the spillway's discharge efficiency and safety performance. Therefore, we propose a scouring-resistant reservoir spillway side-channel design to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a scour-resistant reservoir spillway side channel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A scour-resistant reservoir spillway includes a main body, with symmetrical protective sleeves on the outer surface of the main body. An inlet assembly is located on the right side of the main body. A fixing plate is fixedly connected to the side of each set of protective sleeves that are close to each other. A symmetrical spring is fixedly connected to the right side of each set of fixing plates. A flow-blocking plate is fixedly connected to the right end of each set of springs. Several flow-guiding holes are opened on the outer surface of each flow-blocking plate. A damper is fixedly connected to the right side of each set of fixing plates. The right end of each set of dampers is connected to the left side of the flow-blocking plate. An scour-resistant layer is laid on the inner bottom wall of the main body.

[0007] In a further embodiment, the inlet component includes an inlet channel, the left side of which is connected to the right side of the main body of the flood channel, and a boss is fixedly connected inside the inlet channel.

[0008] In a further embodiment, each set of fixed plates has symmetrical sliding rods slidably connected inside, and the right end of each set of sliding rods is connected to the left side of the baffle plate.

[0009] In a further embodiment, the impact-resistant layer is honeycomb-shaped and is composed of precast high-strength concrete blocks.

[0010] In a further embodiment, a number of energy dissipation piers are fixedly connected to the inner bottom wall of the main body of the flood channel, and the outer surface of each energy dissipation pier is coated with a wear-resistant ceramic coating.

[0011] In a further embodiment, each set of protective sleeves and the upper surface of the flood channel body are provided with screw holes, and each set of screw holes is threaded with bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device incorporates a flow-blocking plate, springs, and dampers. The springs buffer the impact force generated by floodwaters hitting the flow-blocking plate, while the dampers prevent the flow-blocking plate from shaking violently. Simultaneously, the guide holes on the flow-blocking plate divert the floodwaters, reducing their flow velocity and kinetic energy, and minimizing the scouring effect of the floodwaters on the interior of the main channel. The honeycomb-shaped high-strength precast concrete erosion-resistant layer laid on the bottom wall of the main channel directly resists the scouring and abrasion of the main channel by the floodwaters, enhancing its scouring resistance.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model discloses an anti-erosion reservoir spillway side channel type, comprising a main body 1, with symmetrical protective sleeves 2 on the outer surface of the main body 1, an inlet assembly 3 on the right side of the main body 1, a fixing plate 5 fixedly connected to the side of each set of protective sleeves 2 that is close to each other, a symmetrical spring 7 fixedly connected to the right side of each set of fixing plates 5, a flow-blocking plate 6 fixedly connected to the right end of each set of springs 7, a plurality of flow-guiding holes 12 opened on the outer surface of each set of fixing plates 5, a damper 8 fixedly connected to the right side of each set of fixing plates 5, and the right end of each set of dampers 8 connected to the left side of the flow-blocking plate 6, an anti-erosion layer 13 laid on the inner bottom wall of the main body 1, the protective sleeves 2 can protect the inner side wall of the main body 1, and at the same time strengthen the main body 1. The overall structural strength is enhanced by the fixed plate 5, which provides a stable support foundation for the installation of subsequent components. The spring 7 has an elastic reset function. When the flood impacts the baffle plate 6, the spring 7 can undergo elastic deformation, thereby buffering the impact force of the flood and reducing the direct impact of the flood on the interior of the main body 1. The guide hole 12 can divert the flood, reduce the flow velocity and kinetic energy of the flood, and further reduce the scouring of the main body 1. The damper 8 plays a damping and buffering role during the elastic deformation and reset of the spring 7, preventing the baffle plate 6 from shaking violently due to the elastic force of the spring 7, and ensuring the stable operation of the baffle plate 6. The scouring layer 13 can directly resist the scouring and wear of the inner bottom wall of the main body 1 by the flood, and enhance the scouring resistance of the inner bottom wall of the main body 1.

[0023] The inlet component 3 includes an inlet channel 301, the left side of which is connected to the right side of the main body of the flood channel 1. A boss 302 is fixedly connected inside the inlet channel 301. The inlet channel 301 provides a passage for floodwater to enter the main body of the flood channel 1. The boss 302 can buffer the floodwater entering the inlet channel 301 and reduce the impact force of the water flow.

[0024] Each set of fixed plates 5 has a symmetrical sliding rod 9 slidably connected inside. The right end of each set of sliding rods 9 is connected to the left side of the baffle plate 6. The sliding rods 9 can guide the movement of the baffle plate 6, ensuring that the baffle plate 6 can only move left and right along the axis of the sliding rod 9 when it is impacted by flood, avoiding the baffle plate 6 from shifting or tilting, and ensuring the buffering and diversion effect of the baffle plate 6.

[0025] The erosion-resistant layer 13 is honeycomb-shaped. The honeycomb structure has high structural stability and compressive and erosion resistance, which can effectively disperse the impact force of flood on the inner bottom wall of the main channel 1. The erosion-resistant layer 13 is spliced ​​from high-strength precast concrete blocks. The high-strength precast concrete blocks have high strength and wear resistance, and are laid in a splicing manner, which facilitates later maintenance and replacement. When some precast blocks are damaged, only the damaged parts need to be replaced, reducing maintenance costs.

[0026] Several energy dissipation piers 4 are fixedly connected to the inner bottom wall of the main body of the flood channel 1. The energy dissipation piers 4 can block and dissipate the flood inside the main body of the flood channel 1. By changing the trajectory of the water flow, the water flows collide and rub against each other, consuming the kinetic energy of the water flow and reducing the water flow speed, thereby reducing the scouring of the flood on the inner bottom wall and inner wall of the main body of the flood channel 1. The outer surface of each energy dissipation pier 4 is coated with a wear-resistant ceramic coating. The wear-resistant ceramic coating has extremely high wear resistance and impact resistance, which can further enhance the scouring resistance of the energy dissipation pier 4 and extend the service life of the energy dissipation pier 4.

[0027] Each set of protective sleeves 2 and the upper surface of the main body of the flood channel 1 are provided with screw holes 11. Each set of screw holes 11 is threaded with bolts 10. Through the cooperation of bolts 10 and screw holes 11, the protective sleeves 2 can be firmly fixed to the outer surface of the main body of the flood channel 1, preventing the protective sleeves 2 from loosening or falling off during use. It also facilitates the disassembly and installation of the protective sleeves 2, and makes it convenient for the inspection and maintenance of the main body of the flood channel 1 in the future.

[0028] The working principle of this utility model is as follows:

[0029] When the reservoir needs to release floodwater, the floodwater first enters the inlet channel 301. The protrusion 302 diverts the floodwater, splitting it into multiple streams to reduce the impact force of each individual stream. The diverted floodwater then enters the main body of the flood channel 1, first impacting the baffle plate 6. Under the impact of the floodwater, the baffle plate 6 moves to the left. At this time, the spring 7 is compressed, and the elastic force of the spring 7 buffers the impact force of the floodwater. Simultaneously, the damper 8 generates damping force to prevent the baffle plate 6 from shaking violently due to the elastic force of the spring 7. The floodwater passes through the baffle plate... The flow diversion holes 12 on the flow plate 6 divert the flow, further reducing the flow velocity and kinetic energy. Subsequently, the flood passes through the energy dissipation pier 4, which changes the trajectory of the water flow, causing the water flows to collide and rub against each other, consuming the kinetic energy of the water flow and reducing the flow velocity. The scour-resistant layer 13 directly resists the scouring and abrasion of the flood, protecting the inner bottom wall of the main body of the flood channel 1. The protective sleeve 2 protects the inner side wall of the main body of the flood channel 1, enhancing the overall structural strength. Through the synergistic effect of these structures, the scour resistance of the spillway is effectively improved, ensuring the safety of flood discharge.
