Embodiment 1

[0032] combined with Figure 1-8 As shown, the embodiment of the present invention provides a dustpan-shaped water inlet channel with a bionic structure, including a linear inlet section 1 arranged in sequence along the water inlet direction, a dustpan-shaped turning section 2 with a bionic structure, and a bionic trumpet tube rectification section 3;

[0033] The surface of the dustpan-shaped steering section 2 with a bionic structure is provided with an imitation dolphin skin ridge structure, and the imitation dolphin skin ridge structure diffuses from the inlet position of the dustpan-shaped steering section along the water flow direction to the rear wall position of the dustpan-shaped steering section ;

[0034] The structural shape of the rectification section 3 of the bionic trumpet tube is the diversion structure of the walrus head, which is used to rectify the flow state of the water flow before entering the pump device.

[0035] The invention changes the surface stru...

Abstract

The invention relates to a dustpan-shaped water inlet channel with a bionic structure. The channel comprises a linear inlet section, a dustpan-shaped turning section with the bionic structure, and a bionic horn tube rectifying section, which are sequentially arranged in the water inlet direction, wherein the surface of the dustpan-shaped turning section with the bionic structure is provided with adolphin-like skin ridge structure, which spreads from the inlet position of the dustpan-shaped turning section to the position of the back wall of the dustpan-shaped turning section in the directionof water flow; the structural shape of the bionic horn tube rectifying section is a diversion structure of a walrus head, which is used to rectify the flow state of the water before entering a pump device. The water inlet channel structure provided by the invention can reduce the accumulation effect of turbulence on the surface of the dustpan-shaped turning section, avoid the formation of undesirable vortexes, rectify the water flow at the position of the horn tube, and improve the hydraulic performance when the water flow enters the water pump device.

Description

technical field [0001] The invention relates to a dustpan-shaped water inlet channel with a bionic structure, which belongs to the technical field of hydraulic engineering pumping stations. Background technique [0002] The water inlet channel of the pump station is divided into elbow-shaped water inlet channel, bell-shaped water inlet channel and dustpan-shaped water inlet channel according to the shape. Compared with the elbow-shaped water inlet channel, the dustpan-shaped water inlet channel has less strict requirements on the length of the channel; compared with the bell-shaped water inlet channel, the dustpan-shaped water inlet channel has less strict requirements on the width of the channel. In addition, the dustpan-shaped water inlet channel has a simple flow channel line shape and is convenient for construction, and is a better form of the water inlet channel. [0003] Bionic technology solves many engineering problems by drawing on the biological structure that has...
