Embodiment 1

[0031] Example 1: figure 1 , figure 2 with image 3 It is a structural schematic diagram of Embodiment 1 of the present invention. This embodiment 1 includes a trough-shaped water flow channel 1 including at least a side wall 5 and a bottom wall 6. A filter device is arranged in the water flow channel 1, and the filter device includes a bracket 2 and a screen. 3. The screen 3 is a box-shaped body with at least a water-facing surface 10, an upper surface 11 and a lower surface 12. The water-facing surface 10 is a non-vertical surface relative to the horizontal, and a water intake pipe is provided in the middle of the box-shaped body of the filter device 4.

Embodiment 2

[0032] Embodiment 2: Compared with Embodiment 1, this embodiment includes a groove-shaped water flow channel 1 with at least side wall 5 and bottom wall 6. One end of the groove-shaped water flow channel 1 is a water inlet, and the other end is a water outlet. A filter device is provided in the water flow channel 1 , and a sand discharge area 8 is provided between the filter device and the bottom wall 6 of the water flow channel 1 . This filtering device comprises support 2 and screen cloth 3, and screen cloth 3 is at least provided with the box-shaped body of facing water surface 10, upper surface 11 and lower surface 12, and described water facing surface 10 is a non-vertical surface relative to the horizontal, that is, the water facing surface 10 is a non-vertical surface relative to the horizontal. The water surface 10 forms a rhomboid shape with the upper surface 11 and the lower surface 12, and a water intake pipe 4 is arranged at the middle part of the box-shaped body of...

Embodiment 3

[0033] Embodiment 3: Compared with Embodiments 1 and 2, this embodiment includes a groove-shaped water flow channel 1 that is at least provided with a side wall 5, a bottom wall 6 and an upper wall 7, and the groove-shaped water flow channel 1 is a tubular body. One end is a water inlet, and the other end is a water outlet. A filtering device is provided in the water flow channel 1 , and a sand discharge area 8 is provided between the filtering device and the bottom wall 6 of the water flow channel 1 . This filtering device comprises support 2 and screen cloth 3, and screen cloth 3 is at least provided with the box-like body of facing water surface 10, upper surface 11 and lower surface 12, and described water facing surface 10 is a non-vertical surface relative to the horizontal, that is, the water facing surface 10 is a non-vertical surface relative to the horizontal. The water surface 10 forms a rhomboid shape with the top 11 and the bottom 12, and a water intake pipe 4 is p...

Abstract

The invention discloses a method for getting water from a surface water source, an anti-blocking water getting head of the surface water source and a water getting system composed of the anti-blocking water getting head. A groove-shaped water flow channel (1) which at least comprises a side wall (5) and a bottom wall (6) is arranged. A filter unit is arranged in the water flow channel (1) and comprises a support (2) and a screen (3). The screen (3) is a box-like body which at least is provided with a water attaining surface (10), an upper surface (11) and a lower surface (12). The water attaining surface (10) is a non-vertical plane relative to the horizontal plane. A water getting pipe (4) is arranged in the middle of the box-like body of the filter unit. Compared with the prior art, the method has the advantages that while water is gotten efficiently, the problem that the water getting head is blocked after running for a long term can be solved, the water getting head is made to keep the optimum water getting capacity, and meanwhile the problem that a follow-up pipeline or tubular mixer is blocked is effectively solved.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering and relates to the technical field of preventing suspended debris from clogging water intake structures when surface water is drawn, and in particular relates to a method for drawing water from surface water sources, a water intake system and an anti-clogging water intake head used therefor. Background technique [0002] The water intake head generally refers to the water intake part of the water intake structure. The commonly used forms of the water intake head are bell mouth, mushroom shape, fish shape cover, box type, pier type, etc. [0003] At present, the principle of widely used water intake heads to prevent silt and weeds from clogging is generally to first set up a protective fence in the water intake channel and then add a screen (grid) net or metal cap to prevent clogging at the nozzle. [0004] However, judging from the existing practical projects, the long-term operation o...
