Embodiment Construction

[0025] The invention is suitable for the inlet forepool of a multi-unit pump station, and the drawing is designed according to the design requirements.

[0026] A structure for regulating the diffusion and flow of the fore pool of a pump station, including a diversion channel 1, a diffusion fore pool of the pump station 2, a comb-shaped composite plate set in the fore pool, a number of parallel pump inlet pools connected with the fore pool, and an inlet The water pump suction pipe 4 in the pool and the partition 5 between each adjacent inlet pool.

[0027] The comb-shaped composite board is composed of an arc-shaped ribbon-shaped board (comb back) and a shunt board (comb teeth), which are comb-shaped on the plane. The number of splitter plates and the number of piers in the inlet pool ( N g ) Are the same, corresponding one by one; the rear part of the shunt plate (comb) is connected with the arc ribbon plate, and the rear end is flush with the outer side of the arc ribbon plate.

Abstract

The invention discloses a structure and method for regulating diffusion flowing of a pump station forebay, and belongs to the technical field of water conservancy projects. The structure comprises anapproach channel, the forebay, water inlet ponds, separating piers between the water inlet ponds and water pump water sucking pipes in the water inlet ponds and is characterized in that the forebay isprovided with a plurality of flow separating plates and an arc strip plate, the flow separating plates are fixed to the forebay, and are in one-to-one corresponding to the separating piers, the arc strip plate is fixed to the rear ends of the flow separating plates, and the flow separating plates are connected into a comb-shaped combination plate. The structure is suitable for forward water inletforebays of various pump stations. The forebay flowing state can be effectively improved, the vortex and the backflow of the forebay can be removed, the water flow in the forebay and the water inletpond can be more smooth, the good water inlet condition is provided for water inlet of a water pump, the safe and economic operation of a pump station is facilitated, and the structure is simple, technically reliable, easy to implement, small in engineering amount, and large in economic benefit. The structure is technically reliable, easy to implement, obvious in benefit and wide in application prospect.

Description

Technical field [0001] The invention relates to a water intake structure of a pump station project, in particular to a structure for regulating the diffusion flow in the front pool of the pump station (ie comb-shaped composite plate), and a method for regulating the diffusion flow in the front pool of the pump station by using the comb-shaped composite plate. It belongs to the technical field of water conservancy engineering, especially the technical field of hydraulic machinery and pump systems. Background technique [0002] The forepool is an important part of the water intake structure of the pumping station. The flow pattern of the water flow in the forepool directly affects the performance of the pump device, improving the flow pattern of the forepool water flow can provide good water intake conditions for the pump and benefit the pumping station. Economic Operation. The forward inlet of the multi-unit pumping station is trapezoidal on the plane. The diffusion angle of the ...
