Problems solved by technology

[0003] In agricultural irrigation, it is generally necessary to introduce the water in the ditch into the farmland, and then irrigate the crops. The general water diversion structure is to put the water inlet pipe into the ditch, and use the water pump to pump the water into the farmland, but the floating garbage and There is a lot of silt, and direct use of this water will cause serious pollution to the farmland. At the same time, the silt will easily block the water pump and make it inconvenient to clean, making it damaged and reducing the service life of the water pump. Filter heads need to be installed at both the water inlet ends of the water inlet pipes. However, When debris adheres to the filter head at the inlet end of the water inlet pipe, it will affect the water output of the water pump

Embodiment 1

[0030] A water diversion structure used in water conservancy and hydropower projects, such as Figures 1 to 3 , including a drainage channel 1, a sedimentation tank 2, and a filter box 3, the drainage channel 1 communicates with the water inlet provided on the left side of the upper end of the sedimentation tank 2, and the filter box 3 is connected to the right side of the sedimentation tank 2 through a water passage 4, The inside of the filter box 3 is provided with an upper partition 5 and a lower partition 6 successively from left to right, and a filter screen 7 is arranged between the upper partition 5 and the lower partition 6, and the filter screen 7 is arranged from left to right. The filter screen 7 provided with an inclination can improve the area and effect of filtration. The inside of the filter box 3 is provided with an outlet pipe 8 on the right side of the lower partition 6, and the water inlet end of the outlet pipe is located at the bottom of the filter box. Th...

Embodiment 2

[0035] On the basis of Embodiment 1, a filter tank 19 is connected above the sedimentation tank 2 at the right end of the flow channel 1, and a discharge channel 20 is arranged at the right end of the filter tank 19. The miscellaneous filter tank 19 is used to collect floating impurities filtered from the inclined filter plate of the buffer filter plate 17 .

Embodiment 3

[0037] On the basis of Embodiment 2, a buffer filter plate 17 is provided at the water inlet of the sedimentation tank 2 inside the flow channel 1, and the buffer filter plate 17 includes a corrugated buffer baffle and an inclined filter connected to the right end of the corrugated buffer baffle. Plate, buffer filter plate 17 left ends are fixed on the sedimentation tank 2 bottoms by nuts, and buffer filter plates 17 right ends are fixed on the miscellaneous filter tank 19 bottoms by nuts. The corrugated buffer baffle of the buffer filter plate 17 is used to buffer and settle the water in the drainage channel 1 before entering the sedimentation tank 2, thereby reducing the amount of sludge entering the sedimentation tank. The inclined filter plate of the buffer filter plate 17 is used to filter the floating impurities into the miscellaneous filter tank 19 with the shaking of the water when the water enters the sedimentation tank 2, thereby reducing the floating impurities from ...

Abstract

The invention discloses a water diversion structure for water conservancy and hydropower engineering, and belongs to the technical field of water conservancy and hydropower engineering. The water diversion structure comprises a drainage channel, a sedimentation tank and a filter box, the drainage channel communicates with a water inlet formed in the left side of the upper end of the sedimentation tank, the filter box is connected to the right side of the sedimentation tank through a water passing channel, an upper partition plate and a lower partition plate are sequentially arranged in the filter box from left to right, and a filter screen is arranged between the upper partition plate and the lower partition plate; and a water outlet pipe is arranged on the right side of the lower partition plate in the filter box, a water pump is connected to the water outlet pipe, and sludge scraping mechanisms are arranged at the inner bottom of the sedimentation tank and the left side of the lower partition plate at the inner bottom of the filter tank. The water diversion structure is simple in structure, floating impurities and sludge in water can be effectively filtered and removed, the water pump is effectively protected, the service life of the water diversion structure is prolonged, and therefore the water diversion efficiency is improved, and application and popularization are convenient.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, in particular to a water diversion structure used in water conservancy and hydropower engineering. Background technique [0002] Water diversion structures such as aqueducts and sedimentation-filtration-disinfection system processes form the most basic drinking water treatment system recognized by modern people. And it has a wide range of applications in agricultural irrigation and many other life fields. The aqueduct is an important channel structure in water conservancy projects, which plays the role of transporting water sources, diverting water for power generation, and agricultural irrigation. [0003] In agricultural irrigation, it is generally necessary to introduce the water in the ditch into the farmland, and then irrigate the crops. The general water diversion structure is to put the water inlet pipe into the ditch, and use the water pump to pump th...
