Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a stilling pool for drainage of water conservancy projects. Background Art

[0002] The stilling basin is a section of the pool surface at the downstream outlet of a water conservancy discharge. Its application in water conservancy projects is crucial. Its purpose is to slow down the water flow speed to reduce the scouring and damage of the water flow to the downstream structure and protect the safety of water conservancy facilities. It is widely used in projects such as rivers, reservoirs, and hydropower stations.

[0003] The existing energy dissipation pool with a single groove structure has a limited energy dissipation effect on the water flow discharged upstream. Therefore, an energy dissipation pool for water conservancy project drainage is proposed to provide a group of energy dissipation pool structures with good energy dissipation effect for the downstream section of the water conservancy project drainage, and provide a pool bottom structure combined with multi-stage energy dissipation troughs and concrete retaining slopes to effectively slow down and dissipate water flow energy and protect downstream structures from scouring and damage. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an energy dissipation pool for water conservancy project drainage, which provides a group of energy dissipation pool structures with good energy dissipation effect for the downstream section of the water conservancy project drainage, and provides a pool bottom structure combined with multi-stage energy dissipation troughs and concrete retaining slopes, which effectively slows down and dissipates water flow energy and protects downstream structures from scouring and damage.

[0005] The technical solution adopted by the utility model to solve its technical problems is an energy dissipation pool for drainage of water conservancy projects, including a concrete base, a first energy dissipation trough, a second energy dissipation trough and a third energy dissipation trough, and also including a first concrete retaining slope and a second concrete retaining slope. The first energy dissipation trough is arranged at the water inlet end of the top of the concrete base surface, the third energy dissipation trough is arranged at the water outlet end of the top of the concrete base surface, and the second energy dissipation trough is located between the first energy dissipation trough and the third energy dissipation trough.

[0006] By adopting the above technical scheme, a group of energy dissipation pool structures with good energy dissipation effect are provided for the downstream section of the water conservancy project through the first energy dissipation trough, the second energy dissipation trough and the third energy dissipation trough and the first concrete retaining slope and the second concrete retaining slope arranged on the concrete base surface. By setting the first energy dissipation trough, the second energy dissipation trough and the third energy dissipation trough, a pool bottom structure combining multi-stage energy dissipation troughs and concrete retaining slopes is provided for the water conservancy project, which effectively slows down and dissipates the water flow energy and protects the downstream structure from scouring damage.

[0007] Specifically, the first concrete retaining slope and the second concrete retaining slope are both connected to the top of the concrete base surface, and the first concrete retaining slope is located between the first energy dissipation groove and the second energy dissipation groove, and the second concrete retaining slope is located between the second energy dissipation groove and the third energy dissipation groove.

[0008] Specifically, the interior of the first concrete retaining slope is a solid structure, the water-facing surface of the second concrete retaining slope is provided with diversion slots at equal intervals, the drainage surface of the second concrete retaining slope is provided with discharge slots at equal intervals, and the diversion slots are communicated with the discharge slots.

[0009] By adopting the above technical solution, water is allowed to flow out from the inside of the second concrete retaining slope, so that the water flow discharge path is dispersed, thereby achieving a more effective force dissipation effect.

[0010] Specifically, a water retaining plate is provided on the drainage surface of the second concrete retaining slope, and the top of the water retaining plate is connected to the second concrete retaining slope through a hinge.

[0011] By adopting the above technical solution, the impact energy of the water discharged from the discharge groove can be further consumed.

[0012] Specifically, the bottom of the concrete base surface is sequentially connected with anti-collision teeth.

[0013] By adopting the above technical solution, the anti-collision teeth improve the gripping effect of the overall force dissipation structure on the downstream foundation structure, ensuring the stability of the overall efficiency structure when used at the downstream drainage end.

[0014] The beneficial effects of the utility model are as follows: multi-level energy dissipation is achieved through an assembly consisting of a first energy dissipation trough, a second energy dissipation trough and a third energy dissipation trough and a first concrete retaining slope and a second concrete retaining slope arranged on a concrete base surface, thereby providing a group of energy dissipation pool structures with good energy dissipation effects for the downstream section of the water conservancy project. Through the arrangement of the first energy dissipation trough, the second energy dissipation trough and the third energy dissipation trough, a pool bottom structure combined with multi-level energy dissipation troughs and concrete retaining slopes is provided, which effectively slows down and dissipates water flow energy, protects downstream structures from scouring damage, and solves the problem that the existing energy dissipation pool with a single groove structure has a limited energy dissipation effect on the upstream drainage water flow.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] To protect downstream structures from scour damage, such as Figure 1-4 As shown, the utility model describes an energy dissipation pool for drainage of water conservancy projects, comprising a concrete base 1, a first energy dissipation trough 2, a second energy dissipation trough 3 and a third energy dissipation trough 4, and also comprising a first concrete retaining slope 5 and a second concrete retaining slope 6. The first energy dissipation trough 2 is arranged at the water inlet end at the top of the concrete base 1, the third energy dissipation trough 4 is arranged at the water outlet end at the top of the concrete base 1, and the second energy dissipation trough 3 is located between the first energy dissipation trough 2 and the third energy dissipation trough 4.

[0023] When in use, by providing the first energy dissipation trough 2, the second energy dissipation trough 3 and the third energy dissipation trough 4 and the first concrete retaining slope 5 and the second concrete retaining slope 6 on the concrete base surface 1, a group of energy dissipation pool structures with good energy dissipation effect are provided for the downstream section of the water conservancy project drainage. By providing the first energy dissipation trough 2, the second energy dissipation trough 3 and the third energy dissipation trough 4, a pool bottom structure combining multi-stage energy dissipation troughs and concrete retaining slopes is provided for the water conservancy project drainage, which effectively slows down and dissipates water flow energy and protects downstream structures from scouring and damage.

[0024] The utility model also includes that the first concrete retaining slope 5 and the second concrete retaining slope 6 are both connected to the top of the concrete base surface 1, and the first concrete retaining slope 5 is located between the first energy dissipation groove 2 and the second energy dissipation groove 3, and the second concrete retaining slope 6 is located between the second energy dissipation groove 3 and the third energy dissipation groove 4.

[0025] When in use, the first concrete retaining slope 5 is located between the first energy dissipation trough 2 and the second energy dissipation trough 3. The solid structure of the first concrete retaining slope 5 provides stable support and helps to guide water flow into the second energy dissipation trough.

[0026] The utility model also includes that the interior of the first concrete retaining slope 5 is a solid structure, the water-facing surface of the second concrete retaining slope 6 is provided with diversion grooves 61 at equal intervals, the drainage surface of the second concrete retaining slope 6 is provided with discharge grooves 62 at equal intervals, and the diversion grooves 61 are communicated with the discharge grooves 62.

[0027] When in use, the second concrete retaining slope 6 allows water to flow out from the inside of the second concrete retaining slope 6 through the setting of the diversion groove 61 and the discharge groove 62. Part of the water flows through the diversion groove 61 and is discharged from the discharge groove 62 to achieve water dispersion, thereby achieving a more effective force dissipation effect.

[0028] The utility model also includes that a water retaining plate 63 is provided on the drainage surface of the second concrete retaining slope 6, and the top of the water retaining plate 63 is connected to the second concrete retaining slope 6 through a hinge.

[0029] When in use, the water retaining plate 63 can further consume the impact energy of the water discharged from the discharge slot 62 based on its own gravity.

[0030] The utility model also includes that the bottom of the concrete base surface 1 is sequentially connected with anti-collision teeth 7.

[0031] When in use, the anti-collision teeth 7 improve the gripping effect of the overall force dissipation structure on the downstream foundation structure, ensuring the stability of the overall efficiency structure when used at the downstream drainage end.

[0032] When the utility model is in use, the first energy dissipation trough 2 is arranged at the water inlet end of the concrete base surface 1, which is the first part that the water flow contacts, and its function is to initially slow down the water flow speed and reduce the impact force of the water flow. The second energy dissipation trough 3 plays a role in further dissipating the water flow energy, and the purpose is to further reduce the water flow speed and further dissipate the energy by increasing the length and complexity of the water flow path. The third energy dissipation trough 4 serves as the last energy dissipation barrier to ensure that the speed of the water flow has been greatly reduced when it flows out of the energy dissipation pool, and the energy is effectively controlled. The first concrete retaining slope 5 is located between the first energy dissipation trough 2 and the second energy dissipation trough 3. The first concrete retaining slope of the solid structure 5 provides a stable support and helps to guide the water flow into the second energy dissipation trough. The second concrete retaining slope 6 allows the water flow to flow out from the inside of the second concrete retaining slope 6 through the arrangement of the diversion slot 61 and the discharge slot 62, so that the water flow discharge path is dispersed. Part of the water flows through the diversion slot 61 and is discharged from the discharge slot 62 to achieve the dispersion of the water flow, thereby achieving a more effective energy dissipation effect, further dispersing and slowing down the water flow, and the water retaining plate 63 can further consume the impact energy of the water discharged from the discharge slot 62 based on its own gravity, thereby achieving effective control and dissipation of the water flow energy through the multi-stage energy dissipation trough and the concrete retaining slope.
