Embodiment 1

[0031] 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;

[0032] 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 ;

[0033] The structural shape of the rectification section 3 of the bionic trumpet tube is a diversion structure of a walrus head, which is used to rectify the water flow passing through the triangular grooves in the ridge structure imitating dolphin skin.

Abstract

The invention relates to a dustpan-shaped water inlet channel with a bionic structure, which includes a straight line inlet section arranged in sequence along the water inlet direction, a dustpan-shaped steering section with a bionic structure, and a bionic horn tube rectification section; the dustpan-shaped steering section with a bionic structure The surface of the section 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; the structure of the bionic horn tube rectification section The diversion structure in the shape of a walrus head is used to rectify the flow state of the water flow before entering the pump device. The water inlet channel structure of the present invention can reduce the accumulation effect of turbulent flow on the surface of the dustpan-shaped steering section, avoiding the formation of undesirable eddy currents; and rectify the water flow at the position of the trumpet tube to improve the hydraulic performance of the water flow entering 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...
