Technical Field

The invention belongs to the technical field of rural drinking water engineering, and particularly relates to an automatic filter for a branch pipeline opening of a water channel.

Background

Countless small-sized tap water plants are built in China since the construction of drinking water safety projects in rural areas is implemented in 2005, the popularity of tap water reaches over 79 percent in rural areas at present, and the drinking water safety guarantee level in rural areas is remarkably improved. Water sources from these waterworks: according to different local resources, water in a nearby reservoir is directly extracted for purification and water supply; and water sources are also provided for long distance transportation through water channels, and the water channels are introduced into the reservoir through large-scale pipelines from water plants to purify and supply water. Various algae, moss, water plants, leaves and branches float in source water transferred from the ditch, and the impurities not only easily block pipelines and water pump blades, but also increase the cost for purifying water quality. At present, each water works adopts: a movable filter screen cover is covered on the bottom of the ditch and the water inlet of the pipeline for separation. When the surface of the filter screen cover is full of weeds, the weeds are required to be manually cleaned, the filter screen is generally full of weeds within two hours, manual cleaning is required, and a large amount of manpower is wasted due to frequent cleaning work.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides the automatic filter for the branch pipeline opening of the water channel, which has good filtering effect, does not need manpower and electric energy.

In order to achieve the above object, the present invention provides the following solutions: an automatic filter for the branch pipeline of water channel is composed of cylindrical filter net, fixing supporter, axle frame, speed reducer, spiral blades, branch pipeline, brush, bottom surface of water channel, expansion screw, input axle and output axle. The branch pipeline is buried in the lower portion of the bottom surface of the water channel, the fixing support is installed on the bottom surface of the water channel and above the opening of the branch pipeline, and the gearbox is installed above the fixing support. The helical blade is arranged on the input shaft of the reduction gearbox and extends into the inlet of the branch pipeline. The connecting shaft frame is arranged on an output shaft of the reduction gearbox, the outer end of the connecting shaft frame is connected with the cylindrical filter screen, the upper end of the cylindrical filter screen extends out of the upper part of the water flow, and a small gap is reserved between the lower end of the cylindrical filter screen and the bottom surface of the water channel to ensure that the cylindrical filter screen is not clamped in rotation. The brush is fixed on the bottom surface of the ditch and is tightly attached to the outer surface of the cylindrical filter screen.

According to the working principle of the invention, when water flows from right to left through the water channel, a large amount of running water enters the cylinder through the right side meshes of the cylinder filter screen. Water flow into the cylinder: one part flows out through the left side mesh of the cylindrical filter screen; the other part of the water flows into the branch pipeline through the spiral blade and reaches the reservoir of the waterworks. The helical blade rotates at a high speed under the impact of water flow and drives the input shaft of the reduction gearbox to rotate, and after the reduction of the speed of the reduction gearbox, power is output from the output shaft to drive the shaft connecting frame and the cylindrical filter screen to rotate.
