Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.

Referring to fig. 1, a river water drip irrigation device 10 includes a natural sedimentation tank, a primary filter wall 30, a water intake pipe 40, a plurality of drip irrigation pipes 50, and a terminal filter 60, wherein the natural sedimentation tank 20 is communicated with an external canal to introduce river water in the canal into the natural sedimentation tank 20, the primary filter wall 30 is located in the natural sedimentation tank 20, the primary filter wall 30 encloses a clean water tank 300, an inlet of the water intake pipe 40 is located in the clean water tank 300 to allow water in the natural sedimentation tank 20 to be taken away after being filtered by the primary filter wall 30, the water intake pipe 40 is provided with a plurality of outlets, the drip irrigation pipe 50 is communicated with the outlets of the water intake pipe 40, and the terminal filter 60 is disposed on the drip irrigation pipe 50 to further filter water in the clean water tank 300.

In a preferred embodiment, the area of the natural settling pond 20 is at least one mu, and the depth is more than two meters, so that the standing time is more than two days to achieve a good settling effect. The water entering the clean water reservoir 300 actually enters by way of leakage. Because the water in the clean water reservoir 300 has enough capacity, the water flow rate entering the clean water reservoir 300 can be ensured to be small, firstly, the water flow can be prevented from being washed, secondly, large-size suspended substances such as aquatic plants and the like can be prevented from entering the clean water reservoir 300 due to the too fast flow rate, and the water body at the bottom layer can be prevented from entering the clean water reservoir 300 due to stirring. Meanwhile, since the natural settling pond 20 is rich in water and plants, aquatic animals such as fish and tadpoles can be present therein, and the primary filter wall 30 can also isolate the aquatic animals. However, the primary separating wall cannot filter free algae or fine animals. This can cause clogging of the drip irrigation pipe 50 after it enters the end of the drip irrigation pipe 50. By providing the end filter 60 on the drip irrigation pipe 50, it is possible to filter microscopic animals such as algae, wigglers, tadpoles, and the like.

The case of arranging the filter on the water intake pipe 40 is suitable for the case of a constant irrigation area, but in the actual irrigation process, the irrigation area is often uncertain. If the irrigation area exceeds the filtering load of the filter, the filtering effect is not as expected and, in the long run, the drip irrigation pipe 50 is clogged. The filter is arranged on the drip irrigation pipeline 50, so that the newly added drip irrigation pipeline 50 is provided with the filter due to the increase of the irrigation area, and the filtering effect of the filter cannot be influenced.

Further, preliminary filter wall 30 includes cement base wall 301, stone wall 302, filter cloth 303, the upper end and the stone wall 302 overlap joint of cement base wall 301, stone wall 302 is piled up by the stone and is formed, and the water in the natural sedimentation tank 20 passes through the seepage of stone wall 302 and gets into clean water reservoir 300, and filter cloth 303 is located the inboard of clean water reservoir 300, the cladding in the side of stone wall 302.

The provision of primary filter wall 30 must take into account robustness, sustainability and low cost issues. The cement-based wall 301 can ensure the firmness of the wall body. The cement-based wall 301 may be a concrete cavity, or may be built by using square bricks inside and coated with cement mortar outside. Can also be directly placed through the cement hollow bricks. Stone wall 302 may also be reinforced with wood boards, wire, etc. if a more robust environment is desired on site. And in order to further prevent some impurities from passing through the gaps between the stones, a filter cloth 303 is arranged on the inner side of the stone wall 302. The filter cloth 303 can be sewn by using waste clothes and the like, and if the replacement and washing are convenient, the cost is very low.

Further, referring to fig. 2 to 4, the end filter 60 includes a housing 601, a front cover 602, a rear cover 603, a front filter screen 604, a rear filter screen 605, and a middle filter screen 606, two ends of the housing 601 are respectively connected to the front cover 602 and the rear cover 603, the front cover 602 and the rear cover 603 are connected to the drip irrigation pipe 50, the front filter screen 604 is located at a front end of the housing 601, the rear filter screen 605 is located at a rear end of the housing 601, and the middle filter screen 606 is located between the front filter screen 604 and the rear filter screen 605.

In a preferred embodiment, the front filter 604, the rear filter 605 and the middle filter 606 have different filtering manners, wherein the middle filter 606 is a filling filter. The front filter screen 604 and the rear filter screen 605 are in a sheet shape, the meshes of the front filter screen 604 are smaller than those of the rear filter screen 605, the middle filter screen 606 comprises a cylindrical net rack and activated carbon, the activated carbon is filled in the cylindrical net rack, and the diameter of the cylindrical net rack is the same as the inner diameter of the shell body 601. The rear filter net 605 can reduce the load of the activated carbon and intercept the wigglers and other small animals. The middle filter screen 606 plays a main filtering role, and the activated carbon has a good filtering effect on micro algae in the water body, so that the blockage of the drip irrigation pipeline 50, particularly a drip irrigation head, can be further prevented. The front filter screen 604 can block the fragments of the activated carbon and further block finer impurities in the water.

Further, the shell body 601 includes two semi-cylindrical shells, and the front end of shell is equipped with the external screw thread, and is corresponding, and the inner wall of preceding lid 602 is equipped with the internal thread, preceding lid 602 and shell body 601 threaded connection, back lid 603 and shell body 601 joint. Thus, the end filter 60 is very easily removed to replace or clean the filter media therein.

In the installation process of the terminal filter 60, the outlet of the water intake pipe 40 can be provided with an external thread, correspondingly, the rear cover 603 is provided with an internal thread, and the water intake pipe 40 is in threaded connection with the rear cover 603. The front end of the front cover 602 can be provided with a longer pipeline, the diameter of the pipeline is larger than that of the drip irrigation pipeline 50, and the drip irrigation pipeline 50 is flexible and has certain toughness, so that the drip irrigation pipeline 50 can be sleeved on the front cover 602.

Further, the front cover 602 is shaped like a semi-sphere to reduce corrosion caused by cavitation.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
