Description

Technical Field

[0001] This utility model is a field underground pipe irrigation and drainage device, belonging to the field of soil remediation. Background Technology

[0002] Underground pipes are effective for treating saline-alkali land by removing salt. These pipes can be deeply buried and densely installed, allowing for rapid salt removal and enabling controlled groundwater salt drainage, thus achieving continuous and effective improvement of saline-alkali land. After 8-10 years of use, underground pipes inevitably accumulate silt and sand, requiring dredging and maintenance. The dredging and maintenance method involves observing and analyzing through inspection wells. For pipes with significantly reduced outflow or increased sand content, a high-pressure water jet from an underground pipe cleaning machine can be used to clean the entire pipe, flushing out the accumulated sand from the pipe or inspection well. During the cleaning process, the outlet of the underground pipe cleaning machine needs to be connected to the pipe through the inspection well. Due to the long length of the underground pipe, a high-pressure water jet is required, necessitating a high-powered underground pipe cleaning machine, resulting in high energy consumption. Furthermore, the high-pressure water can damage pipes that have been in use for a period of time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a field underground pipe irrigation and drainage device to solve the problems mentioned in the background technology. This utility model reduces the water pressure required for flushing underground pipes and reduces energy consumption.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a field underground irrigation and drainage device, comprising an underground pipe buried in the soil, wherein multiple seepage holes are uniformly formed on the outer surface of the underground pipe, a filter screen for filtering sediment is wrapped around the underground pipe, a flushing pipe arranged along the length of the underground pipe is provided inside the underground pipe, both ends of the flushing pipe are fitted with detachable end caps, multiple small holes are uniformly formed on the outer surface of the flushing pipe, multiple support members are equidistantly installed on the outer surface of the flushing pipe, a straight threaded pipe communicating with the flushing pipe is fixedly connected to the outer surface of the flushing pipe, a connecting pipe is internally threaded to the straight threaded pipe, the outer surface of the connecting pipe is machined with an external thread that mates with the straight threaded pipe, one end of the connecting pipe away from the straight threaded pipe passes through the underground pipe and the filter screen and is connected to a flexible hose, and the other end of the flexible hose is fixedly connected to a shut-off valve for connecting to the outlet of a water pump.

[0005] Furthermore, the support includes three struts, which are fixed in a ring at equal intervals on the outer surface of the flushing pipe. The end of each strut away from the flushing pipe is in contact with the inner wall of the concealed pipe, and the struts are arranged along the radial direction of the concealed pipe.

[0006] Furthermore, a reinforcing rib is fixedly connected between two adjacent support rods, and the reinforcing rib has an arc-shaped structure.

[0007] Furthermore, the outer surface of the rinsing pipe is provided with a circular hole, and the outer surface of the mesh is provided with a through hole aligned with the circular hole. One end of the connecting pipe passes through the through hole and the circular hole in sequence.

[0008] Furthermore, a connector is fixedly connected to one end of the concealed pipe, and the inner diameter of the connector is the same as the outer diameter of the concealed pipe.

[0009] Furthermore, a support ring for limiting the position of the end of the connecting pipe is fixedly connected inside the straight threaded pipe, and a sealing ring is provided between the support ring and the connecting pipe.

[0010] Furthermore, an installation hole is provided at the location where the flushing pipe is installed with the straight threaded pipe, and one end of the straight threaded pipe is fixed in the installation hole.

[0011] The beneficial effects of this utility model are:

[0012] 1. Install flushing pipes inside the concealed pipes, and then install a flexible hose on the flushing pipes to connect to the water pump. When the water pump is working, it delivers flushing water to the flushing pipes through the hoses. The water then enters the flushing pipes and impacts the inner wall of the concealed pipes through small holes, loosening the settled soil and achieving the purpose of cleaning the settled soil. Multiple flushing pipes can be laid in long concealed pipes to achieve segmented cleaning of the concealed pipes. There is no need to use a high-power concealed pipe cleaning machine; a low-power water pump can be used, reducing energy consumption. The low-power water pump generates less water pressure, reducing the strength requirements of the concealed pipes.

[0013] 2. After the flushing tube is inserted into the concealed pipe, align the straight thread on the flushing tube with the round hole on the concealed pipe. Then, pass the connecting tube through the through hole and the round hole and screw it into the straight thread. Connect one end of the hose to the connecting tube to achieve a convenient connection between the hose and the flushing tube, which facilitates the assembly of the flushing tube and the concealed pipe.

[0014] 3. After the flushing pipe is inserted into the concealed pipe, one end of the support rod on the surface of the flushing pipe rests against the inner wall of the concealed pipe. At this time, the support rod plays the role of supporting the concealed pipe and improving the pipe's resistance to compression. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 This utility model provides a technical solution: a field underground irrigation and drainage device, including an underground pipe 1 buried in the soil, wherein multiple seepage holes 2 are evenly opened on the outer surface of the underground pipe 1, and a cylindrical mesh 3 for filtering mud and sand is wrapped around the underground pipe 1. Under the filtration of the cylindrical mesh 3, mud and sand are prevented from randomly entering the underground pipe 1 through the seepage holes 2. A plug pipe 6 with the same inner diameter as the outer diameter of the underground pipe 1 is fixed at one end of the underground pipe 1, so that one end of the plug pipe 6 is inserted into the plug pipe 6 of another underground pipe 1, realizing the connection between two adjacent underground pipes 1, and so on, to complete the connection of multiple underground pipes 1.

[0023] See Figure 1 and Figure 2 Before burying the underground pipe 1, a flushing pipe 9 with multiple small holes 7 evenly distributed on its outer surface is inserted into the underground pipe 1. At this time, the flushing pipe 9 is arranged along the length of the underground pipe 1. Then, detachable end caps 8 are installed at both ends of the flushing pipe 9 to seal the ends of the flushing pipe 9. Because a support structure consisting of three struts 10 fixed at equal intervals in a ring on the outer surface of the flushing pipe 9 is fixed at equal intervals on the outer surface of the flushing pipe 9, after the flushing pipe 9 is inserted into the underground pipe 1, the end of the strut 10 arranged along the radial direction of the underground pipe 1 away from the flushing pipe 9 contacts the inner wall of the underground pipe 1. At this time, the strut 10 plays the role of supporting the underground pipe 1 and improving the compression resistance of the underground pipe 1. An arc-shaped reinforcing rib 13 is fixed between two adjacent struts 10 to improve the stability of the strut 10 installation.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4One end of the straight threaded pipe 11 is fixed in the mounting hole on the outer surface of the flushing pipe 9, thus connecting the straight threaded pipe 11 and the flushing pipe 9. One end of the connecting pipe 12, whose outer surface is machined with external threads, is then screwed into the straight threaded pipe 11 after passing through the through hole 14 on the outer surface of the mesh 3 and the round hole 15 on the outer surface of the flushing pipe 9, which is aligned with the through hole 14. This completes the assembly of the connecting pipe 12 and the straight threaded pipe 11. Because the end of the connecting pipe 12 furthest from the straight threaded pipe 11 is connected to the hose 4, and the other end of the hose 4 is fixedly connected to a shut-off valve 5 for connecting to the water pump outlet, a convenient connection between the hose 4 and the flushing pipe 9 is achieved, facilitating the assembly of the flushing pipe 9 and the concealed pipe 1. After the connecting pipe 12 is screwed into the straight threaded pipe 11, it is blocked by the support ring 16 fixed inside the straight threaded pipe 11, and the connecting pipe 12 is in a... The length of the straight threaded pipe 11 is limited. Continue to tighten the connecting pipe 12 so that the sealing ring 17 between the support ring 16 and the connecting pipe 12 is in a squeezed state, which improves the sealing performance of the connection between the connecting pipe 12 and the straight threaded pipe 11. By inserting a flushing pipe 9 into the concealed pipe 1, and then installing a hose 4 for connecting the water pump on the flushing pipe 9, the water pump delivers flushing water to the flushing pipe 9 through the hose 4 when it is working. Then, the water entering the flushing pipe 9 impacts the inner wall of the concealed pipe 1 through the small hole 7, which loosens the sediment and achieves the purpose of cleaning the sediment. Multiple flushing pipes 9 are laid in the long concealed pipe 1 to achieve segmented cleaning of the concealed pipe 1. There is no need to use a high-power concealed pipe cleaning machine. A low-power water pump can be used to reduce energy consumption. The water pressure generated by the low-power water pump is smaller, which reduces the strength requirements of the concealed pipe 1.
