Description

Technical Field

[0002] PE pipe In China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all have a place, among which the strong development momentum of PE pipes is the most eye-catching.

[0003] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all PE. HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE has excellent resistance to most domestic and industrial chemicals. PE pipe welding, PE pipe butt weld, this method provides the highest reliability and diameter range and pressure process: the end of the pipe is heated, using a tool called "mirror" under the contact pressure and temperature definition, the end is quickly contacted and maintained under pressure, during the cooling process, PE pipes are medium-density polyethylene pipes and high-density polyethylene pipes. Compared with steel pipes, the construction process is simple and has a certain degree of flexibility.

[0004] Since the water source for low-pressure irrigation is underground well water and surface water, which contains a large amount of organic plankton, untreated water is more likely to produce microbial aggregation and reproduction, which will in turn affect the pipeline.

[0005] The existing technology has the following problems:

[0006] In actual use of existing PE pipes, it is not convenient to clean impurities inside the pipes and impurities on the filter screen. The filter screen needs to be manually disassembled for cleaning, which makes the cleaning work very cumbersome and time-consuming, delays production, and reduces the working efficiency of the pipes. At the same time, during the use of existing PE pipes, untreated water sources will cause a layer of dirt to adhere to the inner wall of the pipe. If it is not cleaned for a long time, it will damage the pipe wall, increase water flow resistance, and reduce energy consumption. Utility Model Content

DETAILED DESCRIPTION

[0026] like Figure 1-5 As shown, the utility model provides a low-pressure PE pipe for irrigation with a self-cleaning function, including a connecting sleeve 1, a PE pipe 2 is fixedly sleeved in the middle of the connecting sleeve 1, a connected connecting head 3 is fixedly installed in the middle of the upper end of the connecting sleeve 1, a filtering mechanism 4 is installed inside the connecting head 3, a mounting pipe 5 is movably installed outside the connecting head 3, a cleaning mechanism 6 is installed inside the PE pipe 2, an outer wall of the connecting head 3 is provided with an external thread 31, and an inner wall of the lower end of the mounting pipe 5 is provided with an internal thread 51.

[0027] The external thread 31 and the internal thread 51 are threadedly connected, and the connecting sleeve 1 is connected to the inside of the PE pipe 2.

[0028] Through the filtering mechanism 4, by utilizing the cooperation between the connecting plate 44 and the connecting column 42, the water flow can provide power to drive the connecting plate 44 to rotate when passing through the connecting plate 44. The connecting plate 44 is powered to rotate and drive the cleaning brush 45 to scrub the impurities on the filter plate 41, so as to avoid the impurities accumulating for a long time and blocking the filter plate 41, thereby improving the working efficiency of the pipeline. Through the cleaning mechanism 6, when the water flows through the PE pipe 2, the annular cleaning will move along the inner wall of the PE pipe 2 when impacted by the water flow, and in the process of movement, the annular scrapers 64 on both sides will be driven to scrape the inner wall of the PE pipe 2, thereby cleaning the dirt attached to the inner wall of the PE pipe 2, and preventing the inner wall of the PE pipe 2 from accumulating too much debris as much as possible, thereby improving the self-cleaning ability of the PE pipe 2 during use and improving the convenience of using the PE pipe 2.

[0029] like Figure 3 As shown, the filtering mechanism 4 includes a filter plate 41, the outer end of the filter plate 41 is fixedly connected to the inner wall of the connector 3, a connecting column 42 is installed at the lower end of the filter plate 41, the upper end of the connecting column 42 is rotatably connected to a bearing seat 43, and four groups of connecting plates 44 are symmetrically fixedly installed on the outer wall of the connecting column 42, and a plurality of cleaning brushes 45 are fixedly installed on the upper side of the connecting plate 44.

[0030] The upper end of the bearing seat 43 is fixedly connected to the middle of the lower end of the filter plate 41 , and the cleaning brush 45 is in contact with the surface of the filter plate 41 .

[0031] The connecting plates 44 are distributed around the center of the circle on the outer surface of the connecting column 42 , and the connecting column 42 and the connecting plates 44 are arranged in an impeller shape.

[0032] By removing the mounting tube 5 from the connector 3 , impurities on the filter plate 41 can be cleaned.

[0033] like Figure 4-5 As shown, the cleaning mechanism 6 includes an annular collar 61, the outside of the annular collar 61 is movably connected to the inside of the PE pipe 2, sliders 62 are symmetrically fixedly installed at the four corners of the outer wall of the annular collar 61, support rods 63 are symmetrically fixedly installed at the four corners of the annular collar 61, an annular scraper 64 is fixedly installed on the top of the support rod 63, and the inner wall of the PE pipe 2 is symmetrically provided with slide grooves 65, and limit blocks 66 are symmetrically and movably installed at both ends of the slide grooves 65.

[0034] The slide block 62 matches the slide groove 65 and is slidably connected.

[0035] The outer wall of the annular scraper 64 is in contact with the inner wall of the PE pipe 2 .

[0036] When the annular collar 61 moves, it will drive the slider 62 to slide synchronously in the slide groove 65, thereby ensuring the stability of the annular collar 61 when moving. At the same time, the movement range of the annular collar 61 can be limited by the set limit block 66.

[0037] The following is a detailed description of the working principle of the low-pressure irrigation PE pipe with self-cleaning function.

[0038] like Figure 1-5 As shown, when the low-pressure irrigation PE pipe with self-cleaning function is used, first, the installation pipe 5 can be threadedly connected with the external thread 31 on the connector 3 by using the internal thread 51, so that the installation pipe 5 can be threadedly installed on the connector 3, and then the water flow can be transported into the PE pipe 2 through the installation pipe 5, and the impurities in the water flow will be filtered through the filter plate 41. At the same time, the connecting plate 44 and the connecting column 42 are arranged in an impeller shape. When the water flow passes through the connecting plate 44, it provides a driving force to the connecting plate 44, so that the connecting plate 44 drives the cleaning brush 45 to filter when it moves. The impurities on the surface of the plate 41 are scrubbed to avoid clogging of the filter plate 41, and the water flow after filtering will enter the PE pipe 2, and the water flow in the PE pipe 2 will be drained and discharged through the guidance of the PE pipe 2, thereby facilitating irrigation. When draining water, the annular collar 61 will be impacted by the water flow in the pipe and move along the direction of the water flow. During the movement, the sliding collar will drive the annular scraper 64 to move synchronously through the support rod 63, and then use the annular scraper 64 to scrape the inner wall of the PE pipe 2, thereby achieving the purpose of self-cleaning the inner wall of the pipe.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
