Problems solved by technology

[0003] In the process of pumping water from rivers, lakes or ponds into raw water pipes, pumping pipes are used. The existing pumping pipes are generally inserted directly into rivers, lakes or ponds through a circular pipe to pump water. , when the garbage or algae in the water body are easily sucked into the water during the pumping process, the water quality inside the raw water pipeline will deteriorate, endangering the safety of the water supply system, and the garbage will easily affect the pumping equipment, making it inconvenient to use

Embodiment 1

[0038] Such as figure 1 The shown source pumping pipe for raw water pipelines includes a vertically arranged pumping pipe 4, a filter mechanism for intercepting debris in the water body, and a collection box 2 for collecting debris intercepted by the filter mechanism, wherein:

[0039] Such as figure 1 and figure 2 As shown, the filter mechanism includes a lift-type first filter plate 25 arranged inside the suction pipe 4 and a reset mechanism for driving the first filter plate 25 to reset, such as Figure 7 As shown, the first filter plate 25 is in the shape of a truncated cone, and the outer surface of the first filter plate 25 is in an inclined tooth-like structure. This setting can greatly increase the action area of ​​the first filter plate 25, and can promote the garbage to move upwards along the slope of the first filter plate 25 under the action of the water flow. The toothed structure can make the garbage more concentrated on the first filter plate 25 below. Such...

Embodiment 2

[0044] The difference between this embodiment and embodiment 1 is:

[0045] In this example, if figure 2 and image 3As shown, the top of the first filter plate 25 is provided with a fixed plate 18 whose shape is compatible with it, and the upper end surface of the fixed plate 18 is fixedly connected with the reset mechanism through fixed rods 19 arranged at equal intervals along its circumference. The fixed rods 19 are in one-to-one correspondence with the connecting plates 20, and the upper end of each fixed rod 19 is fixedly connected with the corresponding connecting plates 20, and the lower side of the fixed plates 18 is uniformly fixed with a filter plate 25 for inserting the first filter plate 25. Fixed pin 22 in the upper filter hole. When the first filter plate 25 rises to contact the fixed plate 18, the fixed pin 22 will be inserted into the filter hole of the first filter plate 25, and the sundries blocked in the filter hole can be ejected, so as to protect the f...

Abstract

The invention discloses a source water pumping pipe for a raw water pipeline, and belongs to the technical field of raw water pipelines. The source water pumping pipe comprises a water pumping pipe body, a filtering mechanism and a collecting box, the filtering mechanism comprises a first filter plate arranged in the water pumping pipe body in a lifting mode and a reset mechanism used for driving the first filter plate to reset. At least two side suction pipelines are arranged on the outer side of the water pumping pipe body along the peripheral side at equal intervals, the upper ends and the lower ends of the side suction pipelines are connected with the water pumping pipe body, and the first filter plate is located at the height of the lower ends of the side suction pipelines. The collecting box is installed on the outer side of the water pumping pipe body and located below the side suction pipelines, at least two distribution pipelines are connected between each side suction pipeline and the collecting box, and conveying mechanisms are arranged at the positions, communicating with the distribution pipelines, in the side suction pipelines. According to the device, river water is pumped only through the suction force of a suction pump, meanwhile, impurities in the river water can be automatically intercepted and collected, the filter plate can be cleaned, the automation degree is high, and operation and control are easy and convenient.

Description

technical field [0001] The invention relates to the technical field of raw water pipelines, in particular to a source pumping pipe for raw water pipelines. Background technique [0002] Raw water refers to untreated water. In a broad sense, the water before entering the water treatment process is also called the raw water of the water treatment process. For example, the water sent from the water source to the water treatment plant is called raw water, which is taken from natural water bodies or water storage bodies, such as rivers, lakes, ponds or underground aquifers, and used as water supply sources; or refers to the water that flows into the water treatment plant Water for the first treatment unit. The pipelines that transport raw water are called raw water pipelines. [0003] In the process of pumping water from rivers, lakes or ponds into raw water pipes, pumping pipes are used. The existing pumping pipes are generally inserted directly into rivers, lakes or ponds thr...
