Description

Technical Field

[0001] The utility model relates to the technical field of guide piers, in particular to a guide pier with stepped finger-shaped guide plates. Background Art

[0002] A Chahe water transfer station typically refers to a water conservancy facility located along a specific river (such as a Chahe River). Its primary function is to mechanically lift or transfer river water to meet irrigation, water supply, and drainage needs. These facilities play a vital role in agricultural irrigation, urban water supply, and flood control and drainage. A forebay is a connecting structure located between the canal and the penstock to ensure a smooth transition between flow patterns. It is a key component of a non-pressure diversion hydropower station or water transfer station. To minimize damage to the forebay, a diversion pier is required.

[0003] Previous diversion piers at the Chahe water transfer station had the following shortcomings: 1. They could not quickly dissipate the impact of the water flow; 2. The alternating flow of water through the water supply pipes caused vertical vortexes and eddies, which seriously affected the flow pattern entering the Chahe water transfer station forebay and caused impact damage to the forebay. Therefore, those skilled in the art have proposed a diversion pier with stepped finger-shaped guide plates to address the problems mentioned in the background art. Utility Model Content

[0004] The main purpose of the utility model is to provide a guide pier with stepped finger-shaped guide plates to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A diversion pier with a stepped finger-shaped diversion plate comprises a forebay, a U-shaped water inlet, a water supply pipe and a river diversion dustpan outlet;

[0007] The U-shaped water inlet is provided with strip foundations arranged at equal distances at the bottom of one end, and water supply pipes are fixed to both ends of the top of the strip foundation through L-shaped positioning seats. Separation baffles are built at equal distances in the U-shaped water inlet, and the separation baffles divide the U-shaped water inlet into multiple independent energy dissipation bins, and energy dissipation steps are built at the bottom of the energy dissipation bins. Energy dissipation blocks integrally formed with the separation baffles are provided at equal distances on the inner wall of the energy dissipation bin, and the energy dissipation blocks are located at the top of each level of energy dissipation steps. The other end of the U-shaped water inlet is connected to a front pool, and the water outlet of the front pool is built with finger-shaped guide plates at equal distances.

[0008] As a further solution of the present invention: the L-shaped positioning seat is fixed on the strip foundation by positioning bolts, and an arc-shaped groove is provided on the inner side of the L-shaped positioning seat and the arc-shaped groove is close to the water supply pipe. The L-shaped positioning seat and the positioning bolts are used to facilitate the limiting and fixing of the water supply pipe to prevent displacement caused by water impact.

[0009] As a further solution of the present invention: the front pool is in a rectangular trumpet shape, and water retaining blocks are built on both sides of the water outlet of the front pool.

[0010] As a further solution of the present invention: a front sealing plate is provided at the end of the U-shaped water inlet and at the top of the energy dissipation step, and one end of the water supply pipe passes through the front sealing plate and is located in the energy dissipation chamber.

[0011] As a further solution of the present invention: a water collecting chamber is built on one end of the top of the strip foundation, and the other end of the water supply pipe passes through the water collecting chamber.

[0012] As a further solution of the present invention: a river diversion dustpan mouth is built at one end of the water collecting chamber and the river diversion dustpan mouth is connected to the water collecting chamber. The water output from the Chahe water transfer station is collected through the river diversion dustpan mouth and dispersed through the water collecting chamber into the water supply pipe for transportation.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The water output from the Chahe water transfer station is collected through the river diversion dustpan outlet and dispersed into the water supply pipe through the water collection chamber for transportation. When the turbulent water flow in the water supply pipe enters the stilling chamber in the U-shaped water inlet, the stilling steps and the stilling blocks on both sides are used to quickly eliminate the impact force of the water flow, so as to avoid vertical vortexes and eddies caused by alternating bright and full water flow after the water flow passes through the water supply pipe, which seriously affects the flow state entering the forepool, and reduces the impact damage to the forepool, so that the water flow is smoothly collected in the forepool and finally flows out from the water outlet of the forepool. The multiple groups of finger-shaped guide plates set at the outlet further play the role of diversion and water interception, reduce the water flow rate, and make the treated water flow out smoothly and dispersedly.
