Description
Technical Field
[0001] The utility model relates to the field of municipal drainage, and more specifically to a waterfall energy dissipation facility of a regulating pool. Background Art
[0002] As a regulating and storage facility, the regulating reservoir is widely used in both diverter and combined sewer systems. Its main functions include two aspects: on the one hand, it is to regulate the peak flow when the rainfall exceeds the standard; on the other hand, it is to control the initial rainwater pollution or the combined sewer CSO (overflow pollution control).
[0003] Due to the current status of urban development and construction and the elevation of the drainage system, the regulating reservoir is often located underground. According to the record in Article 4.4.6 of the Technical Specifications for Urban Rainwater Regulation Engineering (GB51174-2017), the design effective water depth of the regulating reservoir built in Shanghai is 2.8m-18.45m, and the design effective water depth of the regulating reservoir built in Kunming is 4.55m-11.6m. It can be seen that the design effective water depth of the regulating reservoir is mostly 4m and above. Therefore, the access to the regulating reservoir from the drainage system must be through a waterfall. The energy dissipation method commonly used at present is not good. The water flow drop is large, which will generate large kinetic energy, and have a great impact on the hydraulic conditions and structure during operation.
[0004] Therefore, it is necessary to develop a waterfall energy dissipation facility for a regulating reservoir that can enhance the energy dissipation effect and ensure safe and stable operation. Summary of the invention
[0005] The purpose of the utility model is to overcome the shortcomings of the above-mentioned background technology and to provide a waterfall energy dissipation facility for a regulating reservoir.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a waterfall energy dissipation facility of a regulating reservoir, characterized in that it includes a well chamber, a water inlet channel located at the top of the left side of the well chamber, and a water outlet channel located at the bottom of the right side of the well chamber, wherein multiple layers of waterfall plates are arranged from top to bottom in the well chamber, and energy dissipation plates are arranged under each layer of the waterfall plates, and the waterfall plates and energy dissipation plates are both connected to the inner wall of the well chamber, and circular holes are opened on the waterfall plates.
[0007] In the above technical solution, each layer of the drop board includes an inner wall left drop board connected to the left inner wall of the well chamber and a right drop board connected to the right inner wall of the well chamber, and the right drop board is located below the left drop board; the gap between the left drop board and the right drop board is a water outlet gap.
[0008] In the above technical solution, each layer of the energy dissipation plate includes a left energy dissipation plate connected to the left inner wall of the well chamber and a right energy dissipation plate connected to the right inner wall of the well chamber, and the right energy dissipation plate is located below the left energy dissipation plate; the gap between the left energy dissipation plate and the right energy dissipation plate is a water outlet gap.
[0009] In the above technical solution, the area of the circular holes on each layer of the drop plate increases successively from top to bottom.
[0010] In the above technical solution, a pebble energy dissipation layer is arranged on the upper surface of the energy dissipation plate.
[0011] In the above technical solution, a bottom pebble energy dissipation layer is provided on the inner wall of the bottom of the well chamber.
[0012] In the above technical solution, the left drop board and the right drop board cover the water outlet gap in the vertical direction.
[0013] In the above technical solution, the left energy dissipation plate and the right energy dissipation plate cover the water outlet gap in the vertical direction.
[0014] In the above technical solution, the top elevation of the water outlet channel is more than 200 mm lower than the right drop board of the lowest layer.
[0015] In the above technical solution, the net distance between each layer of the drop board and the energy dissipation board thereunder is 500mm-2000mm.
[0016] Compared with the prior art, the utility model has the following advantages:
[0017] 1) The utility model provides circular holes on the drop plates, and the circular hole area of each drop plate gradually increases from top to bottom, so that the flow direction of the incoming water is improved from a single forward direction to two directions, forward direction and vertical downward direction, thereby improving the energy dissipation efficiency and the flow state of the water.
[0018] 2) The utility model dissipates the energy of water falling through the circular hole of the drop board on the same side and the horizontal drop board on the opposite side by arranging pebble energy dissipation layers on the left and right energy dissipation boards, thereby enhancing the energy dissipation effect.
[0019] 3) The utility model arranges the drop board and the energy dissipation board alternately in the vertical direction, and arranges the left drop board and the right drop board, and the left energy dissipation board and the right energy dissipation board alternately in the horizontal direction. In the vertical direction, the left drop board and the right drop board, and the left energy dissipation board and the right energy dissipation board just cover the water outlet gap, so as to ensure that the incoming water entering the drop energy dissipation facility can directly fall on the drop board or the energy dissipation board, and the energy dissipation speed is gradually dissipated from top to bottom to ensure the energy dissipation effect.

DETAILED DESCRIPTION

At the same time, the advantages of the utility model will become clearer and easier to understand through the description.
[0026] Referring to the attached drawings, it can be seen that a waterfall energy dissipation facility of a regulating reservoir is characterized in that it includes a well chamber 1, a water inlet channel 2 located at the top left side of the well chamber 1, and a water outlet channel 3 located at the bottom right side of the well chamber 1, wherein multiple layers of waterfall plates 4 are arranged from top to bottom in the well chamber 1, and energy dissipation plates 5 are arranged under each layer of the waterfall plates 4, and the waterfall plates 4 and energy dissipation plates 5 are both connected to the inner wall of the well chamber 1, and a circular hole 41 is opened on the waterfall plate 4.
[0027] Each layer of the drop board 4 includes an inner wall left drop board 42 connected to the left inner wall of the well chamber 1 and a right drop board 43 connected to the right inner wall of the well chamber 1, and the right drop board 43 is located below the left drop board 42; the gap between the left drop board 42 and the right drop board 43 is a water outlet gap 6.
[0028] Each layer of the energy dissipation plate 5 includes a left energy dissipation plate 51 connected to the left inner wall of the well chamber 1 and a right energy dissipation plate 52 connected to the right inner wall of the well chamber 1, and the right energy dissipation plate 52 is located below the left energy dissipation plate 51; the gap between the left energy dissipation plate 51 and the right energy dissipation plate 52 is a water outlet gap 6.
[0029] The area of the circular holes 41 on each layer of the water drop plate 4 increases from top to bottom.
[0030] The upper surface of the energy dissipation plate 5 is provided with a groove, and the groove has a pebble energy dissipation layer 53 to improve the energy dissipation efficiency.
[0031] The inner wall at the bottom of the well chamber 1 is provided with a bottom pebble energy dissipation layer 11 to improve energy dissipation efficiency.
[0032] The left drop board 42 and the right drop board 43 cover the water outlet gap 6 in the vertical direction, and all water from the water inlet channel 2 will directly fall on the left drop board 42 and the right drop board 43, thereby achieving the technical purpose of water drop energy dissipation.
[0033] The left energy dissipation plate 51 and the right energy dissipation plate 52 cover the water outlet gap 6 in the vertical direction, and all water from the water inlet channel 2 will directly fall on the left drop plate 42 and the right drop plate 43, thereby achieving the technical purpose of drop energy dissipation.
[0034] The top elevation of the water outlet channel 3 is more than 200 mm lower than the right drop plate 43 of the lowest layer.
[0035] The net distance between each layer of the drop board 4 and the energy dissipation board 5 therebelow is 500mm-2000mm.
