Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and specifically relates to an anti-clogging water conservancy pipeline used in water conservancy projects. Background Technology

[0002] Water transport pipelines are a type of pipeline used for water transport. However, with the development of technology, people have increasingly higher requirements for water transport pipelines, which has led to the inability of traditional water transport pipelines to meet people's needs. People need new types of water transport pipelines that can prevent pipeline blockage, clean up pipeline debris, and effectively improve the efficiency of water transport. However, existing water pipelines do not have the function of filtering impurities in the water, making them prone to blockage and thus affecting the flow of water. Utility Model Content

[0003] In view of this, the present invention provides an anti-clogging water pipe for water conservancy projects. The anti-clogging pipe is detachably installed between the inlet pipe and the outlet pipe. Impurities in the water are filtered through a filter screen to achieve the anti-clogging function. At the same time, the anti-clogging pipe is easy to disassemble, and the filter screen is easy to remove and replace.

[0004] The technical solution is as follows: A clog-resistant water conservancy pipeline for water conservancy projects includes an inlet pipe and a drain pipe. An anti-clogging pipe is provided between the inlet pipe and the drain pipe. An annular mounting frame is fixedly installed inside the anti-clogging pipe. An annular frame is detachably installed on the annular mounting frame, and a filter screen is fixedly installed on the annular frame.

[0005] During use, the above technical solution involves detachably installing the anti-clogging pipe between the inlet and outlet pipes.

The first mounting flange and the second mounting flange are connected and fixed by connecting bolts and nuts.

[0008] Preferably, a tapered groove is fixed on the first mounting flange, and a tapered cylinder is fixed on the second mounting flange, with the tapered cylinder inserted into the tapered groove.

[0009] Preferably, a U-shaped pipe is fixedly installed on the anti-clogging pipe, the U-shaped pipe is located on both sides of the filter screen, a drain pipe is installed on the anti-clogging pipe between the U-shaped pipe and the filter screen, the drain pipe is located on the side closer to the water inlet pipe, a second solenoid valve is installed on the anti-clogging pipe between the drain pipe and the U-shaped pipe, a first solenoid valve is fixedly installed on the drain pipe, a third solenoid valve is fixedly installed on the U-shaped pipe, and a fourth solenoid valve is fixedly installed on the drain pipe.

[0010] Preferably, the anti-blocking pipe is equipped with a controller, and the first solenoid valve, the second solenoid valve, the third solenoid valve and the fourth solenoid valve are all electrically connected to the controller.

[0011] During the use of the above technical solution: when backwashing of the filter screen is required, the first and second solenoid valves are closed, and the third and fourth solenoid valves are opened. The water transported by the inlet pipe is transported through the U-shaped pipe to the other side of the filter screen in the U-shaped pipe to backwash the filter screen, and the impurities are discharged through the sewage pipe.

[0012] Preferably, a pressure measuring device is installed on the anti-clogging pipe between the filter screen and the water inlet pipe, and the pressure measuring device is electrically connected to the controller.

[0013] Preferably, the pressure measuring device includes a pressure measuring cavity fixedly installed on the anti-clogging pipeline, a piston plate is slidably installed in the pressure measuring cavity, a piston rod is fixedly installed on the piston plate, a first detection contact is fixedly installed on the piston rod, a second detection contact is detachably installed in the pressure measuring cavity, and an elastic component is provided between the pressure measuring cavity and the piston plate, which drives the first detection contact away from the second detection contact.

[0019] 3. The water pressure at the inlet pipe is detected in real time by a pressure measuring device. When the filter screen is clogged or the flow is incomplete, the piston plate pushes the piston rod to move, so that the first detection contact and the second detection contact come into contact, thereby sending a signal.

[0038] A U-shaped pipe 13 is fixedly installed on the anti-clogging pipe 7. The U-shaped pipe 13 is located on both sides of the filter screen 19. A drain pipe 15 is installed on the anti-clogging pipe 7 between the U-shaped pipe 13 and the filter screen 19. The drain pipe 15 is located on the side closer to the water inlet pipe 1.
