Description

Technical Field

[0001] This application relates to the field of irrigation technology, and in particular to an anti-clogging dripper, drip irrigation pipe and water-saving irrigation system. Background Technology

[0002] Drip irrigation is a precise irrigation method that delivers water droplets, one by one, evenly and slowly into the soil near the crop root zone through emitters or orifices installed on drip irrigation pipes. This minimizes water leakage and loss, ensuring timely supply of water to the crop root zone and maintaining suitable soil moisture. This facilitates the activity of water, fertilizer, air, heat, and microorganisms in the soil, keeping it in optimal condition and creating favorable conditions for high and stable crop yields. Double-perforated emitters are widely used due to their larger water output per emitter. Chinese Patent Publication No. CN 205694737 U discloses a miniature anti-clogging single-hole embedded emitter and drip irrigation tape, in which a labyrinthine turbulent groove is formed around the inlet hole on the front of the emitter to meet the requirements of dripping water.

[0003] However, in actual use, there will be impurities in the water flowing in the drip irrigation pipe. Larger impurities in the water (large sand particles or grass leaves) will block the water inlet in the drip irrigation pipe, while smaller impurities (silt) will accumulate in the labyrinth turbulence groove, causing internal blockage. This will make the dripper prone to failure and reduce the reliability of the drip irrigation pipe.

[0004] Therefore, the technical problem to be solved in this application is how to design a technology that improves anti-clogging performance to enhance the reliability of drip irrigation pipes. Summary of the Invention

[0005] This application provides an anti-clogging dripper, a drip irrigation pipe, and a water-saving irrigation system, which improves the anti-clogging performance of the dripper to enhance the reliability of the drip irrigation pipe.

[0006] To achieve the above objectives, this application adopts the following technical solution:

Multiple alternating water-blocking ribs are provided on both sides of the turbulent flow groove along the water flow direction. The water-blocking ribs are provided with a recess on the flow-facing surface. The recess is configured to guide the flowing water to form a vortex.

[0009] The second surface of the drip head body is provided with a water inlet groove; two first ribs are arranged side by side in the water inlet groove, and the water inlet hole is located between the two first ribs; a plurality of guide plates are arranged side by side in the water inlet hole, the guide plates are arranged at an angle relative to the first ribs, and water guide ribs are also provided on both sides of the guide plates extending out of the water inlet hole and extending to the end of the water inlet groove, the water guide ribs being connected to the first ribs on the corresponding sides;

[0010] Two adjacent guide plates form a first water inlet area in the water inlet groove, and a second water inlet area is formed between the sides of two adjacent guide ribs on the same first rib.

[0011] The dripper body has an overall elongated structure, with the water inlet hole located at one end of the dripper body and the water outlet groove located at the other end of the dripper body.

[0012] Furthermore, the recess is also configured to guide the flowing water toward the water-blocking ribs arranged in a staggered manner upstream of the water flow.

[0013] Furthermore, the water-blocking rib extends at an angle away from the direction of water flow within the turbulent groove;

[0014] The end of the flow-facing surface of the water-blocking rib is also provided with a flow-guiding surface, which extends obliquely along the water flow direction in the turbulent groove.

[0015] The guide surface is configured to guide the flowing water toward the water-blocking ribs arranged in a staggered manner downstream of the water flow.

[0016] Furthermore, the recessed portion is arranged at the root of the water-blocking rib;

[0017] The back surface of the water-blocking rib forms a water-blocking surface; the water-blocking surface extends obliquely away from the direction of water flow in the turbulent groove;

[0018] The water-retaining surface is configured to guide water to flow towards the water-retaining ribs arranged in a staggered manner upstream of the water flow.

[0019] Furthermore, a second rib is provided in the water inlet groove. The second rib is arranged to the side of the first rib and extends along the extension direction of the first rib. The second rib is provided with spaced protrusions, and a water flow interval is formed between two adjacent protrusions.

[0020] Furthermore, the water-guiding rib extends in a direction perpendicular to the first rib, and the protrusion is arranged opposite to the second water inlet area at the corresponding position.

[0021] Furthermore, the height of the second rib is greater than the height of the first rib;

[0022] A first buffer groove is formed between the second rib and the adjacent first rib, and a second buffer groove is formed between the second rib and the inner wall of the water inlet groove.

[0023] Furthermore, the bottom surface of the second buffer groove extends at an angle from the outside to the inside toward the water inlet hole.

[0024] Furthermore, the end of the guide plate away from the water inlet groove has a rounded structure.

[0025] This application also provides a drip irrigation pipe, including a pipe body and the aforementioned anti-clogging dripper. The anti-clogging dripper is disposed on the inner wall of the pipe body. An inlet cavity is formed between the inlet hole of the anti-clogging dripper and the inner wall of the pipe body. A turbulent channel is formed between the turbulent groove of the anti-clogging dripper and the inner wall of the pipe body. An outlet cavity is formed between the outlet groove of the anti-clogging dripper and the inner wall of the pipe body.

[0026] The pipe body is provided with a number of water outlet holes, and the water outlet holes are connected to the corresponding cavities.

[0027] This application also provides a water-saving irrigation system, including a main water supply pipe and multiple drip irrigation pipes, wherein the multiple drip irrigation pipes are respectively connected to the main water supply pipe, and the drip irrigation pipes are the drip irrigation pipes described above.

[0028] The technical solution of this application has the following advantages over the prior art: By providing recessed portions on the baffles of the turbulent flow groove, with the recessed portions formed on the flow-facing surface of each baffle, when the water flows into the recessed portion during the flow in the turbulent flow groove, the concave structure of the recessed portion causes the water flow to swirl at that location, forming a vortex. Under the action of the vortex, sediment cannot accumulate on the flow-facing surface of the baffle that obstructs the water flow. The sediment will be carried away by the vortex formed by the recessed portion and eventually enter the outlet groove for output. In this way, the problem of excessive sediment accumulation in the turbulent flow groove can be reduced. In case of blockage, the water in the drip irrigation pipe flows into the inlet hole through the inlet groove of the dripper body. On the one hand, the first ribs on both sides of the inlet hole can protect the edges of the inlet hole to reduce large particles of mud and sand from entering the inlet hole directly from one side. On the other hand, the first inlet area formed by the guide plate and the second inlet area formed by the side of the guide rib can realize that the inlet hole can enter water from three directions to effectively prevent blockage, so as to ensure that the inlet hole can enter water normally, thereby improving the anti-blockage performance of the dripper and improving the reliability of the drip irrigation pipe.

[0041] Example 1, as Figures 1-6 As shown, this application provides an anti-clogging dripper, including a dripper body 100, wherein a water inlet hole 110 is provided on the dripper body 100, and the water inlet hole 110 penetrates the dripper body 100;

[0042] The first surface of the dripper body 100 is provided with a turbulent flow groove 120 and a water outlet groove 130. The turbulent flow groove 120 is distributed around the outside of the water inlet hole 110. One end of the turbulent flow groove 120 is connected to the water inlet hole 110, and the other end of the turbulent flow groove 120 is connected to the water outlet groove 130. Multiple alternating water-blocking ribs 121 are provided on both sides of the turbulent flow groove 120 along the water flow direction. A recessed portion 122 is provided on the flow-facing surface of the water-blocking rib 121. The recessed portion 122 is configured to guide the flowing water to form a vortex.

[0043] The second surface of the drip head body 100 is provided with a water inlet groove 140; two first ribs 150 are arranged side by side in the water inlet groove 140, and the water inlet hole 110 is located between the two first ribs 150; a plurality of guide plates 160 are arranged side by side in the water inlet hole 110, the guide plates 160 are arranged at an angle relative to the first ribs 150, and the guide plates 160 extend out of the water inlet hole 110 and extend to both sides of the end of the water inlet groove 140, and the guide plates 170 are connected to the first ribs 150 on the corresponding side;

[0044] Two adjacent guide plates 160 form a first water inlet area in the water inlet groove 140, and a second water inlet area is formed between the sides of two adjacent guide ribs 170 on the same first rib 150;

[0045] The dripper body 100 has an overall elongated structure, the water inlet hole 110 is arranged at one end of the dripper body 100, and the water outlet groove 130 is arranged at the other end of the dripper body 100.

[0046] Specifically, a turbulence groove 120 and a water outlet groove 130 are formed on the first surface of the dripper body 100, and a water inlet groove 140 is formed on the second surface of the dripper body 100. The first and second surfaces of the dripper body 100 are arranged opposite to each other, and the water inlet hole 110 penetrates the dripper body 100.

[0047] After the dripper body 100 is machined on the inner wall of the drip irrigation pipe, the first surface of the dripper body 100 is combined with the inner wall of the drip irrigation pipe, thereby forming a water inlet cavity between the water inlet hole 110 and the inner wall of the pipe, forming a turbulent channel between the turbulent groove 120 and the inner wall of the pipe, and forming a water outlet cavity between the water outlet groove 130 and the inner wall of the pipe.

[0048] During use, the water in the pipe is subjected to water pressure during the flow process. The water will flow from the inlet groove 140 into the inlet hole 110. The water in the inlet hole 110 is turbulently processed by the water-blocking ribs 121 in the turbulent flow groove 120 and finally flows into the outlet groove 130.

[0049] As water flows through the turbulent flow groove 120, the water flow is blocked by the water-blocking ribs 121 arranged alternately on both sides of the turbulent flow groove 120 along the water flow direction, thus creating turbulence. However, as the water flow is blocked by the water-blocking ribs 121, impurities (silt) in the water flow are blocked by the multiple water-blocking ribs 121 at the water inlet end of the turbulent flow groove 120. After prolonged use, the water-blocking ribs 121 at the water inlet end of the turbulent flow groove 120 will become clogged due to excessive accumulation of silt.

[0050] Therefore, a recessed portion 122 is provided on the flow-facing surface of the water-blocking rib 121. The shape of the recessed portion 122 is designed to guide the water flow to form a vortex in the area where the recessed portion 122 is located. For example, the concave surface of the recessed portion 122 can be an arc surface. In this way, the water flow will be guided by the arc surface to form a vortex after passing through the recessed portion 122.

[0051] Under the action of the eddy, the eddy water flow can carry away the mud and sand left by the obstruction at the front surface of the water-blocking rib 121 with the eddy, thereby reducing the accumulation of mud and sand on the front surface of the water-blocking rib 121 and the blockage of the turbulent groove 120, thus improving the anti-clogging performance.

[0052] As the water flows from the water inlet groove 140 into the water inlet hole 110, the water can enter the water inlet hole 110 from the first water inlet area. At the same time, the water can also flow into the water inlet hole 110 from the second water inlet area formed on the side of the water guide rib 170, thus realizing water intake from three directions.

[0053] In this way, if a blockage occurs in any direction during the water intake process, water can still enter through other directions, thereby improving the anti-blocking performance.

[0054] By providing recesses 122 on the baffle ribs 121 of the turbulent flow groove 120, with the recesses 122 formed on the flow-facing surface of each baffle rib 121, during the flow of water in the turbulent flow groove 120, when the water flows into the recesses 122, the concave structure of the recesses 122 causes the water flow to swirl at that location, forming a vortex. Under the action of the vortex, sediment cannot accumulate on the flow-facing surface of the baffle ribs 121 that obstructs the water flow. The sediment is carried away by the vortex formed by the recesses 122 and eventually enters the outlet groove 130 for output. In this way, the blockage of the turbulent flow groove 120 due to excessive sediment accumulation can be reduced; at the same time, for In the water inlet groove 140 of the dripper body 100, as water in the drip irrigation pipe flows into the water inlet hole 110 through the water inlet groove 140, on the one hand, the first ribs 150 on both sides of the water inlet hole 110 can protect the edges of the water inlet hole 110 to reduce large particles of mud and sand from directly entering the water inlet hole 110 from one side. On the other hand, the first water inlet area formed by the guide plate 160 and the second water inlet area formed by the side of the guide rib 170 can realize water inlet hole 110 from three directions to effectively prevent clogging, so as to ensure that the water inlet hole 110 can enter water normally, thereby improving the anti-clogging performance of the dripper and improving the reliability of the drip irrigation pipe.

[0055] In one embodiment, the recess 122 is further configured to guide the flowing water toward the water-blocking ribs 121 that are staggered and adjacent to each other upstream of the water flow.

[0056] Specifically, in addition to forming eddies, the recessed portion 122 on the water-blocking rib 121 in the turbulent groove 120 will also cause the water to flow towards the water-blocking rib 121 located upstream and staggered on the other side of the turbulent groove 120 under the action of the eddies.

[0057] In this way, the water flowing in the turbulent groove 120 will also have a tendency to flow in the opposite direction, reducing the flow velocity of the water in the turbulent groove 120 and enhancing the turbulence capacity of the turbulent groove 120, so as to make the drip irrigation effect better.

[0058] Furthermore, the water-blocking rib 121 extends inclinedly away from the direction of water flow within the turbulent groove 120;

[0059] The end of the flow-facing surface of the water-blocking rib 121 is also provided with a flow-guiding surface 123, which extends obliquely along the water flow direction in the turbulent groove 120.

[0060] The guide surface 123 is configured to guide the flowing water toward the water-blocking ribs 121 arranged in a staggered manner downstream of the water flow.

[0061] Specifically, the water-blocking rib 121 extends at an angle away from the direction of water flow to enhance its blocking effect on the water flow.

[0062] The guide surface 123 provided at the flow-facing end of the water-blocking rib 121 can also guide the water flow towards the downstream adjacent water-blocking rib 121 on the other side of the turbulent groove 120. Under the guidance of the guide surface 123, the water flow will be diverted towards the recess 122 of the next water-blocking rib 121, so that the recess 122 of the downstream water-blocking rib 121 will generate better vortices.

[0063] Furthermore, the recessed portion 122 is arranged at the root of the water-blocking rib 121;

[0064] The back surface of the water-blocking rib 121 forms a water-blocking surface 124; the water-blocking surface 124 extends obliquely away from the direction of water flow in the turbulent groove 120.

[0065] The water-blocking surface 124 is configured to guide water to flow towards the water-blocking ribs 121 that are staggered and adjacent to each other upstream of the water flow.

[0066] Specifically, a water-blocking surface 124 is formed on the back surface of the water-blocking rib 121. The water-blocking surface 124 guides the vortex formed by the downstream water-blocking rib 121 to be restricted after impacting the water-blocking surface 124. Part of the water flow that forms the vortex will flow back to the water-blocking rib 121 that generates the vortex, so as to improve the effect of the vortex in dispersing impurities and improve the anti-clogging ability.

[0067] In one embodiment of this application, a second rib 180 is further provided in the water inlet groove 140. The second rib 180 is arranged on the side of the first rib 150 and extends along the extension direction of the first rib 150. The second rib 180 is provided with spaced protrusions 190, and a water flow interval is formed between two adjacent protrusions 190.

[0068] Specifically, a second rib 180 is provided on one side of the first rib 150, and an outwardly protruding protrusion 190 is provided on the second rib 180. The protrusion 190 can further block mud and sand and other debris, so that the water flowing through the water flow interval into the water inlet 110 can be filtered by the protrusion 190.

[0069] Furthermore, the water guide rib 170 extends in a direction perpendicular to the first rib 150, and the protrusion 190 is arranged opposite to the second water inlet area at the corresponding position.

[0070] Specifically, regarding the water guide rib 170, the water guide rib 170 extends from the edge of the guide plate 160 toward the outside of the water inlet hole 110. The extension direction of the water guide rib 170 is perpendicular to the first rib 150 and directly faces the water flow gap formed between two adjacent protrusions 190 at the corresponding position. This allows the water flowing through the water flow gap toward the water inlet hole 110 to impact the water guide rib 170. The mud and sand mixed in the water flow can be blocked by the water guide rib 170, further playing the role of filtering mud and sand.

[0071] Preferably, the height of the second rib 180 is greater than the height of the first rib 150;

[0072] A first buffer groove 101 is formed between the second rib 180 and the adjacent first rib 150, and a second buffer groove 102 is formed between the second rib 180 and the inner wall of the water inlet groove 140.

[0073] Specifically, regarding the adjacent first rib 150 and second rib 180 in the water inlet groove 140, the height of the outer second rib 180 is higher than the height of the first rib 150. This results in the depth of the first buffer groove 101 being greater than the depth of the second buffer groove 102. In actual use, after the water flow is filtered by the protrusion 190 of the second rib 180, sediment can be deposited in the first buffer groove 101, and the sediment in the first buffer groove 101 can flow out with the water flow.

[0074] The height of the second rib 180 is greater than that of the first rib 150, which can minimize the amount of sediment flowing into the first rib 150. Water flowing over the second rib 180 towards the first rib 150 will be blocked by the water guide rib 170 to further filter the sediment. The filtered sediment is deposited in the second buffer groove 102, and the sediment in the second buffer groove 102 can flow out with the water flow.

[0075] The bottom surface of the second buffer groove 102 extends obliquely from the outside to the inside toward the water inlet hole 110.

[0076] Specifically, the surface of the dripper body 100 that fits against the tube body is usually an arc surface. To this end, the overall depth of the second buffer groove 102 is increased. The bottom surface of the second buffer groove 102 is arranged at an inclination so that the bottom surface of the second buffer groove 102 can conform to the surface of the dripper body 100 to maximize the depth of the second buffer groove 102. In particular, the second buffer groove 102 is the deepest part adjacent to the second rib 180 to more effectively meet the requirements of sediment deposition and thus improve the filtration effect.

[0077] Furthermore, in order to improve the smoothness of water intake through the water inlet 110, the end of the guide plate 160 away from the water inlet groove 140 has a rounded structure.

[0078] Specifically, multiple guide plates 160 are arranged side by side along the length of the inlet hole 110. Water flowing into the inlet hole 110 will flow towards the turbulent groove 120. Since the ends of the guide plates 160 adjacent to the pipe body are rounded, water resistance can be effectively reduced, so that the water entering the inlet hole 110 can flow smoothly towards the turbulent groove 120, improving the smoothness of water discharge.

[0079] Example 2: Based on Example 1 above, another embodiment of this application provides a drip irrigation pipe, including a pipe body and an anti-clogging dripper as described in the above embodiment. The anti-clogging dripper is disposed on the inner wall of the pipe body. An inlet cavity is formed between the inlet hole of the anti-clogging dripper and the inner wall of the pipe body. A turbulent channel is formed between the turbulent groove of the anti-clogging dripper and the inner wall of the pipe body. An outlet cavity is formed between the outlet groove of the anti-clogging dripper and the inner wall of the pipe body.

[0080] The pipe body is provided with a number of water outlet holes, and the water outlet holes are connected to the corresponding cavities.

[0081] Example 3, based on Example 2 above, as follows Figures 7-12 As shown, another embodiment of this application also provides a water-saving irrigation system, including a main water supply pipe 3 and multiple drip irrigation pipes 5, wherein the multiple drip irrigation pipes 5 are respectively connected to the main water supply pipe, and the drip irrigation pipes 5 are the drip irrigation pipes in the above embodiment two.

[0082] Furthermore, the main water supply pipe 3 is provided with multiple openings, and each opening is provided with a pipe connector.

[0083] The pipe connector includes a first connector 1 and a second connector 2. The first connector 1 has a first through hole 11 and a connecting plate 12 at one end. The edge of the connecting plate 12 has an outwardly extending insertion portion 13, and the outer periphery of the first connector 1 also has an external thread section. The first through hole 11 also penetrates the connecting plate 12. The second connector 2 has a second through hole 21, and one end of the second through hole 21 forms a first internal thread hole 211. The second connector 2 is connected to the first connector 1 through the first internal thread hole 211 and the external thread section, forming a clamping and sealing space between the second connector 2 and the connecting plate 12. The clamping and sealing space is configured to clamp the wall of the main water supply pipe.

[0084] Specifically, the pipe connector in this application is assembled from a first connector 1 and a second connector 2. The first connector 1 and the second connector 2 cooperate to be assembled into the opening provided on the main water supply pipe 3, so that the water in the main water supply pipe 3 can flow out through the first through hole 11 and the second through hole 21. The second connector 2 is connected to a drip irrigation pipe, so that the water flowing out from the second through hole 21 will enter the drip irrigation pipe and flow to the corresponding irrigation area.

[0085] For the pipe connector, one end of the first connector 1 is provided with a connecting plate 12, and an outwardly extending insertion part 13 is provided on the edge of the connecting plate 12. The size of the insertion part 13 is smaller than the opening size of the main water supply pipe 3, so that during on-site installation, the insertion part 13 can be easily inserted into the opening for guidance. After the insertion part 13 is inserted into the opening, the first connector 1 is further rotated so that the connecting plate 12 rotates into the opening and finally positions the connecting plate 12 inside the main water supply pipe 3 and abuts against the inner wall of the main water supply pipe 3. The second connector 2 is external to the main water supply pipe 3 and engages with the external thread on the first connector 1 through the first internal thread hole 211, thereby threading the second connector 2 onto the first connector 1. After the second connector 2 is tightened onto the first connector 1, the end face of the second connector 2 opposite to the connecting plate 12 will press against the pipe wall of the main water supply pipe 3. In this way, the pipe wall of the main water supply pipe 3 located near the outer periphery of the opening is squeezed between the end of the connecting plate 12 and the second connector 2, thereby achieving a sealing treatment of the opening of the main water supply pipe 3.

[0086] In daily use, since the pipe connector can be assembled onto the main water supply pipe 3 on site, holes can be drilled directly on the main water supply pipe 3 to form an opening according to the irrigation requirements of different areas. Then, the first connector 1 is guided by the insertion part 13 so that the connecting plate 12 is inserted into the main water supply pipe 3, and then sealed and fixed by the second connector 2. The drip irrigation pipe can then be connected through the pipe connector.

[0087] The insertion part 13 of the first connector 1 of the pipe connector is inserted into the opening, the connecting plate 12 of the first connector 1 is attached to the inner wall of the main water supply pipe 3, and the outer periphery of the opening of the main water supply pipe 3 is clamped in the clamping and sealing space of the pipe connector; the drip irrigation pipe is connected to the corresponding second connector 2 of the pipe connector.

[0088] Furthermore, to facilitate the installation of drip irrigation pipes, the irrigation system also includes a multi-port pipe 4, which includes an installation connector 41 and at least one external connector 42. The external connector 42 is connected to the installation connector 41. The installation connector 41 is disposed in the second through hole 21 of the second connector 2, and the drip irrigation pipe is connected to the corresponding external connector 42.

[0089] Specifically, in order to reduce the number of openings and meet the installation requirements of multiple drip irrigation tubes, the drip irrigation tubes to be installed on the tube connector are connected by a multi-port pipe 4. During the connection process, the multi-port pipe 4 is threaded into the second internal threaded hole 212 through the mounting connector 41, and the drip irrigation tube can then be installed onto the corresponding external connector 42.

[0090] To improve connection reliability, the external connector 42 and the drip irrigation pipe can be connected in a conventional quick-connect method. For example, the external connector 42 is also provided with a locking sleeve 43, the drip irrigation pipe is inserted into the external connector 42, and the drip irrigation pipe is sealed between the external connector 42 and the locking sleeve 43.

[0091] Specifically, when assembling the drip irrigation tube, the tube opening is placed over the outside of the external connector 42 and inserted into the locking sleeve 43. Then, the locking sleeve 43 moves outward with the threaded engagement of the external connector 42 so that the end of the drip irrigation tube is pressed between the locking sleeve 43 and the external connector 42.

[0092] Furthermore, in order to facilitate the operator to accurately and smoothly insert the insertion part 13 into the opening of the main water supply pipe 3, the insertion part 13 has a pointed structure, and one side of the insertion part 13 forms an inclined surface 14.

[0093] Specifically, the insertion part 13 has a pointed structure along its outward extension direction, so that during operation, the operator can accurately insert the insertion part 13 into the opening through the pointed tip of its head.

[0094] During the rotation of the first connector 1, the side of the insertion part 13 that is squeezed by the edge of the opening forms an inclined surface 14. With the guidance of the inclined surface 14, the first connector 1 can rotate more smoothly during the rotation, so as to smoothly rotate the connecting plate 12 into the opening and improve the convenience of operation.

[0095] Furthermore, the inclined surface 14 is configured to guide the insertion part 13 to be spirally inserted into the water supply pipe in a direction inclined to the center line of the opening of the main water supply pipe 3. Specifically, when the first connector 1 is connected to the opening of the main water supply pipe 3, the first connector 1 is first inclined so that the insertion part 13 is inserted into the opening. The added inclined surface 14 can effectively guide the pipe wall around the opening of the main water supply pipe 3 to slide to the upper surface of the connecting plate 12 during the inclined rotation, so as to reduce the excessive force on the edge of the opening during the rotation and prevent damage. By using the rotational guidance method of a car tire on a wheel hub, the large-sized connecting plate 12 can be inserted into the small-sized opening, ultimately meeting the requirements of on-site drilling and installation.

[0096] Furthermore, in order to facilitate the operator to apply rotational driving force to the first connector 1, the cross-sectional shape of the first through hole is non-circular.

[0097] Specifically, the cross-section of the first through hole is non-circular, so that a tool can be inserted into the first through hole to apply external force during the rotation of the first connecting member 1. For example, the cross-section of the first through hole can be quincunx-shaped, triangular, or rectangular, etc.

[0098] Furthermore, in order to improve the sealing of the opening, the end face of the second connector 2 opposite to the connecting plate 12 is provided with at least one annular rib 22, which surrounds the outer periphery of the first through hole.

[0099] Specifically, the second connector 2 has protruding annular ribs 22 on its end face opposite to the connecting plate 12. After the second connector 2 is connected to the first connector 1 and the wall of the main water supply pipe 3 is sandwiched between them, the annular ribs 22 will further press against the outer wall of the main water supply pipe 3. At the same time, the annular ribs 22 are also distributed around the periphery of the opening. In this way, the annular ribs 22 further press the pipe wall around the opening onto the connecting plate 12, effectively improving the sealing performance of the opening.

[0100] As needed, multiple annular ribs 22 can be provided on the end face of the second connector 2, and the multiple annular ribs 22 are arranged concentrically.

[0101] The two adjacent annular ribs 22 are configured to form a sealing zone on the wall of the water supply pipe.

[0102] Specifically, multiple annular ribs 22 tightly press the wall of the main water supply pipe 3 onto the connecting plate 12, and a sealing area with good sealing performance will be formed between two adjacent annular ribs 22. The sealing area surrounds the opening to improve the sealing performance of the outer periphery of the opening.

[0103] Furthermore, the outer wall of the second connector 2 is also provided with a lever 23.

[0104] Specifically, during the tightening of the second connector 2, the operator can apply a rotational driving force to the second connector 2 using the lever 23, so that the operator can install the second connector 2 without tools.

[0105] Furthermore, in order to meet the requirements of the external drip irrigation pipe, a second internal threaded hole 212 is provided at the other end of the second through hole 21. The second internal threaded hole 212 is coaxially arranged with the first internal threaded hole 211, and the diameter of the second internal threaded hole 212 is larger than the diameter of the first internal threaded hole 211.

[0106] Specifically, the second internal threaded hole 212 is used to meet the connection requirements of the external drip irrigation pipe. The design of making the diameter of the first internal threaded hole 211 smaller than that of the second internal threaded hole 212 ensures that the second connector 2 can be tightened and assembled in place during the tightening process of the second connector 2 to the first connector 1, thereby ensuring the reliability of the sealing connection between the pipe connector and the main water supply pipe 3.

[0107] Based on the above irrigation system, this application also provides a method for assembling the irrigation system, including:

[0108] Drill holes in the main water supply pipe 3 to create multiple openings.

[0109] Specifically, the location of the opening on the main water supply pipe 3 can be set according to the distribution of the irrigation area on site, so that the opening can be as close as possible to the irrigation area, thereby shortening the overall length of the drip irrigation pipe.

[0110] The first connector 1 is tilted relative to the opening, and the insertion part 13 is inserted into the opening. Then, the first connector 1 is rotated, causing the connecting plate 12 to rotate into the opening and abut against the inner wall of the main water supply pipe 3. Specifically, after the opening is made, the first connector 1 is installed into the corresponding opening on site. Therefore, how to conveniently install the first connector 1 is the key to determining whether the technology can be promoted. During the process of installing the first connector 1 into the opening, the insertion part 13 is used as a guide, and the first connector 1 is gradually rotated so that the connecting plate 12 is screwed into the opening, and finally the connecting plate 12 abuts against the inner wall of the main water supply pipe 3. Preferably, by providing an inclined surface 14 in the insertion part 13, during assembly, the first connector 1 is first arranged at an inclination and the insertion part 13 is inserted into the opening. Then, during the rotation of the first connector 1, as the connecting plate 12 gradually enters the main water supply pipe 3, the first connector 1 is also gradually flattened. Finally, the connecting plate 12 is completely inserted into the main water supply pipe 3 and abuts against the inner wall of the main water supply pipe 3.

[0111] The second connector 2 is threaded onto the first connector 1, and the pipe wall of the main water supply pipe 3 is sealed and clamped between the second connector 2 and the connecting plate 12. Specifically, after the first connector 1 is inserted into the opening, the second connector 2 is threaded onto the first connector 1 and the area around the opening is sealed.

[0112] Finally, connect the drip irrigation tube to the corresponding second connector 2.

[0113] By providing a connecting plate on the first connector with an outwardly extending insertion part, during use, operators can drill holes in the main water supply pipe at the construction site according to irrigation requirements to form an opening. Then, the insertion part of the first connector is inserted into the opening and rotated. Guided by the insertion part, the connecting plate can rotate into the main water supply pipe and abut against the inner wall of the main water supply pipe. The second connector is then threaded onto the first connector. At this time, the pipe wall of the main water supply pipe surrounding the opening will be sealed and clamped between the second connector and the connecting plate to achieve a sealing treatment of the opening. The drip irrigation pipe can then be connected to the corresponding second connector to achieve communication with the main water supply pipe and supply water. Since the first connector can be installed on the main water supply pipe on-site, it is convenient for operators to install on-site. Thus, according to the actual distribution needs of the irrigation area, holes can be drilled on-site at the corresponding positions of the main water supply pipe to install the pipe connector. This makes it convenient for operators to assemble the pipe connector onto the main water supply pipe on-site, improving the convenience of on-site installation and thus increasing the flexibility and convenience of use.

[0114] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
