Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a stilling basin for water diversion and drainage in water conservancy projects. Background Technology

[0002] An energy dissipation pool is a section of the pool surface at the downstream outlet of a water conservancy project. Its application in water conservancy projects is crucial. Its purpose is to slow down the water flow to reduce the scouring and damage to downstream structures and protect the safety of water conservancy facilities. It is widely used in projects such as rivers, reservoirs, and hydropower stations.

[0003] A search revealed a Chinese patent application with patent number 202421897074.5, which discloses a stilling basin for water diversion and drainage in a water conservancy project. The stilling basin includes a concrete base, a first stilling trough, a second stilling trough, and a third stilling trough. It also includes a first concrete retaining wall and a second concrete retaining wall. The first stilling trough is located at the water inlet end of the top of the concrete base, and the third stilling trough is located at the water outlet end of the top of the concrete base.

[0004] While the aforementioned patent effectively slows down and dissipates water flow energy, protecting downstream structures from scouring damage, it still has the following shortcomings during use: During the process of dissipating water flow energy through this structure, siltation is prone to occur inside the second and third stilling channels. As the operating time progresses, the continuous accumulation of sediment in the channels will cause the depth of the stilling channels to gradually decrease, thereby reducing the overall energy dissipation efficiency and ultimately affecting the long-term energy dissipation effect of the structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stilling basin for water diversion and drainage in water conservancy projects. It solves the problem that during the process of dissipating energy through water flow using this structure, siltation easily occurs inside the second and third stilling basins. As the operating time progresses, the continuous accumulation of sediment in the basins leads to a gradual decrease in the depth of the stilling basins, thereby reducing the overall energy dissipation efficiency and ultimately affecting the long-term energy dissipation effect of the structure.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a stilling basin for water diversion and drainage in a water conservancy project, comprising a concrete base surface, a first buffer groove provided above the concrete base surface, retaining plates provided on both sides of the concrete base surface, mounting seats installed on both retaining plates, a turbulence shaft rotatably connected between the two mounting seats, and a stepped stilling section provided above the concrete base surface.

[0007] Preferably, the stepped stress-relief section includes a flow block connected above the concrete base surface, and the flow block has at least four stepped grooves.

[0008] Preferably, a stress-reducing frame is fixedly connected above the advection block, and a baffle is rotatably connected inside the stress-reducing frame.

[0009] Preferably, a pair of triangular blocks are connected above the concrete base, and the two triangular blocks are located at the front end of the first buffer groove.

[0010] Preferably, the four stepped grooves are arranged vertically from top to bottom.

[0011] Preferably, at least three fixed piles are connected below the concrete base.

[0012] This utility model provides a stilling basin for water diversion and drainage in hydraulic engineering. Compared with the prior art, it has the following advantages:

[0013] This type of stilling basin for water diversion and drainage in water conservancy projects interacts with a rotating turbulence shaft when the water flows through the first buffer tank, which not only dissipates energy but also prevents siltation. Furthermore, the four stepped troughs running vertically from top to bottom further prevent siltation and help extend the service life of the stilling basin. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a stilling basin for water diversion and drainage in a water conservancy project, including a concrete base 100, a first buffer trough 101 above the concrete base 100, retaining plates 102 on both sides of the concrete base 100, mounting seats 103 on both retaining plates 102, and a flow-dissipating shaft 104 rotatably connected between the two mounting seats 103. A stepped stilling section is provided above the concrete base 100. The flow-dissipating shaft 104 can be installed by setting the mounting seats 103 on both sides. The flow-dissipating shaft 104 is located in the first buffer trough 101, which can not only dissipate the force of the water flow, but also prevent the accumulation of silt in the first buffer trough 101, which is beneficial to improving the service life of the structure.

[0022] Please see Figures 1 to 3 The present invention provides a technical solution: the stepped stress dissipation part includes a flow block 110 connected above the concrete base surface 100. The flow block 110 has at least four stepped grooves 111. The four stepped grooves 111 can dissipate stress and further place mud and sand to accumulate, which is beneficial to improving the use effect.

[0023] Please see Figures 1 to 4 The present invention provides a technical solution: a stress-relief frame 112 is fixedly connected above the flow block 110, and a baffle 113 is rotatably connected inside the stress-relief frame 112. The baffle 113 rotates inside the stress-relief frame 112, and after the water flow comes into contact with the baffle 113, it pushes the baffle 113 to deflect, thereby further achieving the energy dissipation effect.

[0024] Please see Figures 1 to 3 This utility model provides a technical solution: a pair of triangular blocks 114 are connected above the concrete base surface 100. The two triangular blocks 114 are set at the front end of the first buffer trough 101. By setting the two triangular blocks 114 at the front end of the first buffer trough 101, the impact force of the water flow can be dispersed in advance, thereby preventing the first buffer trough 101 from being eroded by the water flow for a long time, which would cause damage to the concrete. This makes it more practical.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: four stepped grooves 111 are arranged vertically from top to bottom, thereby preventing the accumulation of mud and sand and making it more convenient to use.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: at least three fixed piles 115 are connected below the concrete base surface 100. The setting of fixed piles 115 helps to improve the stability of the concrete base surface 100 after it is poured.

[0027] During operation (or use): First, the stability of the concrete base 100 is enhanced by the action of the fixed piles 115. After the water flows in from the position of the first buffer tank 101, the impact force is dispersed by the triangular block 114. Then, the water flow drives the turbulence shaft 104 to rotate, which can prevent the accumulation of silt in the first buffer tank 101 and also has the effect of dissipating the energy of the water flow. Next, the water flow impacts the deflectable baffle 113 on the horizontal block 110. The kinetic energy is further weakened by the deflection of the baffle 113. Finally, after flowing through the four stepped tanks 111 to dissipate energy step by step, it is discharged from the stilling pool. While effectively dissipating the impact force of the water flow, it also avoids the deposition of silt and ensures a long-term stable energy dissipation effect.
