Description

Technical Field

[0001] This utility model relates to the field of underground drip irrigation equipment technology, and in particular to a high-efficiency underground drip irrigation equipment. Background Technology

[0002] Underground drip irrigation equipment is a precision irrigation device that buries drip irrigation pipes (drip tape or drip pipe) underground and delivers water and nutrients directly to the root zone of crops through a low-pressure drip irrigation system. Its core feature is concealed irrigation, which reduces water evaporation and waste and improves water and fertilizer utilization. It is mainly suitable for field crops, cash crops, fruit trees, landscaping and other scenarios that require long-term water-saving management.

[0003] Traditional underground drip irrigation systems require the installation of water supply pipes and drippers. The drippers are installed directly on the pipes. Traditional dripper installation is relatively complex and has weak anti-clogging performance, making installation time-consuming and labor-intensive, which affects the overall installation process. Therefore, a high-efficiency underground drip irrigation system is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency underground drip irrigation device, which effectively solves the deficiencies of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a high-efficiency underground drip irrigation device, including a water delivery pipe, wherein a connection hole is provided on the outer wall of the water delivery pipe, and a first outer shell and a second outer shell are fastened to the outer wall of the water delivery pipe near the connection hole. The inner wall of the first housing is equipped with a connecting pipe that matches the connecting hole, and a water outlet groove is opened on the top surface of the first housing. A sealing cover is installed at the top of the inner wall of the water outlet groove. An internal support frame is installed inside the water outlet trough, and multiple installation slots are installed inside the water outlet trough. Each of the multiple installation slots is equipped with an arc-shaped elastic sheet facing the water outlet direction, and the ends of two adjacent arc-shaped elastic sheets are close to each other. The first and second outer shells have cavities inside that are away from the connecting pipe, and arc-shaped filter blocks are installed inside both cavities. Multiple water outlet holes are opened at the ends of the first and second outer shells away from the connecting pipe.

[0006] Preferably, in any of the above solutions, the first and second outer shells are connected on adjacent sides by pins, and two locking blocks are installed on the other side of the second outer shell. Two buckles that engage with the locking blocks are installed on the other side of the first outer shell. This solution facilitates the connection of one side of the first and second outer shells, and the other side can be engaged with the locking blocks and buckles, so that the first and second outer shells are stably locked onto the outer wall of the water pipe. With the pre-applied adhesive, the first and second outer shells are stably connected to the water pipe, preventing gaps from causing mud and sand to enter.

[0007] Preferably, in any of the above solutions, the connecting pipe is interference-fitted with the connecting hole, and one end of the connecting pipe enters the interior of the water supply pipe. This solution facilitates stable communication between the connecting pipe and the water supply pipe. At the same time, the interference fit can limit the first outer shell during the installation stage and stabilize the installation position of the first outer shell. Subsequently, it is convenient to push the second outer shell to engage the buckle and the locking block, so that the first and second outer shells are fastened to the outer wall of the water supply pipe.

[0008] Preferably, the top of the inner wall of the water outlet tank is stepped, and the top surface of the sealing cover is flush with the top surface of the first outer shell. In this design, the stepped shape of the top of the water outlet tank facilitates the installation of the sealing cover. At the same time, the edge of the sealing cover is fixedly connected to the top of the water outlet tank by laser welding to achieve a seal on the water outlet tank and prevent external mud and sand from entering the interior of the water outlet tank.

[0009] Preferably, in any of the above solutions, the bottom surface of the sealing cover is equipped with multiple blocking rods, which are located at the ends of two adjacent arc-shaped elastic sheets. By using this solution, during the water outage phase, the arc-shaped elastic sheets are bent under pressure due to the negative pressure of the pipeline and the soil pressure. The blocking rods block the ends of two adjacent arc-shaped elastic sheets, and the ends of the arc-shaped elastic sheets are stacked on each other to achieve the purpose of sealing.

[0010] Preferably, one of the above-mentioned solutions is that an arc-shaped groove is provided on the side of the two arc-shaped filter blocks away from the water outlet, and the top arc-shaped groove is connected to the water outlet groove. By using this solution, it is easy to connect the arc-shaped groove and the water outlet groove, thereby increasing the water outlet area and facilitating the outward flow of water through the arc-shaped filter blocks and the water outlet, thus ensuring the uniformity of irrigation.

[0011] This utility model has the following advantages: 1. This high-efficiency underground drip irrigation equipment, by setting a first outer shell and a second outer shell, which are fastened to the outer wall of the water supply pipe by snap-fit ​​and locking blocks, makes the installation more convenient and facilitates on-site construction. The connecting pipe enters into the interior of the water supply pipe, and multiple arc-shaped elastic plates and sealing caps are installed inside the water outlet channel. Multiple water outlet holes are opened at the ends of the first and second outer shells, which facilitates the formation of water outlet channels and facilitates efficient water supply to the external soil. When the underground drip irrigation system stops water supply, the soil pressure or negative pressure in the pipe causes the ends of two adjacent arc-shaped elastic plates to bend and stack on each other, thereby sealing the water channel. With the help of two arc-shaped filter blocks, it can effectively prevent silt and roots from entering and causing blockage.

[0012] 2. This high-efficiency underground drip irrigation equipment has a water outlet groove on the top surface of the first outer shell. The water outlet groove is connected to the connecting pipe and two cavities respectively, thereby forming a wider water outlet channel, which makes the whole has better anti-clogging performance and longer service life. The inner support frame facilitates the support of the sealing cover to resist the pressure of the external soil on the sealing cover and prevent the sealing cover from deforming.

The inner wall of the first outer shell 2 is equipped with a connecting pipe 9 that matches the connecting hole 8. The top surface of the first outer shell 2 is provided with a water outlet groove 11, and the top of the inner wall of the water outlet groove 11 is equipped with a sealing cover 4. An internal support frame 12 is installed inside the water outlet 11. Multiple installation slots 15 are installed inside the water outlet 11. Each of the multiple installation slots 15 has an arc-shaped elastic sheet 13 facing the water outlet direction installed inside, and the ends of two adjacent arc-shaped elastic sheets 13 are close to each other. The first outer shell 2 and the second outer shell 3 have cavities inside that are away from the connecting pipe 9, and arc-shaped filter blocks 10 are installed inside both cavities. Multiple water outlet holes 5 are opened at the ends of the first outer shell 2 and the second outer shell 3 away from the connecting pipe 9. The multiple water outlet holes 5 are evenly distributed on the end faces of the first outer shell 2 and the second outer shell 3. On the one hand, this facilitates the flow of water, and on the other hand, it, together with the arc-shaped filter blocks 10, blocks external mud and sand, and prevents external mud and sand from entering the interior of the water outlet tank 11 when the water is stopped.

[0017] The first outer shell 2 and the second outer shell 3 are connected on adjacent sides by pins. Two locking blocks 7 are installed on the other side of the second outer shell 3, and two buckles 6 that engage with the locking blocks 7 are installed on the other side of the first outer shell 2. As an optional technical solution of this utility model, this facilitates the connection of one side of the first outer shell 2 and the second outer shell 3, and the other side can be engaged with the buckles 6 through the locking blocks 7. This allows the first outer shell 2 and the second outer shell 3 to be stably locked onto the outer wall of the water pipe 1. With the pre-applied adhesive, the first outer shell 2, the second outer shell 3 and the water pipe 1 are stably connected, and gaps are prevented from causing mud and sand to enter.

[0018] The connecting pipe 9 is interference-fitted with the connecting hole 8, and one end of the connecting pipe 9 enters the interior of the water supply pipe 1. As an optional technical solution of this utility model, this facilitates the stable connection between the connecting pipe 9 and the water supply pipe 1. At the same time, the interference fit can limit the first outer shell 2 during the installation stage and stabilize the installation position of the first outer shell 2. Then, it is convenient to push the second outer shell 3 to make the buckle 6 engage with the buckle block 7, so that the first outer shell 2 and the second outer shell 3 are fastened to the outer wall of the water supply pipe 1.

[0019] The top of the inner wall of the water outlet 11 is stepped, and the top surface of the sealing cover 4 is flush with the top surface of the first outer shell 2. As an optional technical solution of this utility model, the stepped shape of the top of the water outlet 11 facilitates the installation position of the sealing cover 4. At the same time, the edge of the sealing cover 4 is fixedly connected to the top of the water outlet 11 by laser welding to achieve the sealing of the water outlet 11 and prevent external mud and sand from entering the interior of the water outlet 11.

[0020] Multiple blocking rods 14 are installed on the bottom surface of the sealing cover 4. The multiple blocking rods 14 are located at the ends of two adjacent arc-shaped elastic sheets 13. As an optional technical solution of this utility model, this facilitates the bending of the arc-shaped elastic sheets 13 under pressure during the water outage stage due to the negative pressure of the pipeline and the soil pressure. The blocking rods 14 block the ends of two adjacent arc-shaped elastic sheets 13, and the ends of the arc-shaped elastic sheets 13 are stacked on each other to achieve the purpose of sealing.

[0021] Two arc-shaped filter blocks 10 have an arc-shaped groove 16 on the side away from the water outlet 5. The top arc-shaped groove 16 is connected to the water outlet 11. As an optional technical solution of this utility model, this facilitates the connection between the arc-shaped groove 16 and the water outlet 11, thereby increasing the water outlet area and making it easier for water to flow outward through the arc-shaped filter block 10 and the water outlet 5, thus ensuring the uniformity of irrigation.

[0022] This high-efficiency underground drip irrigation equipment requires the following steps to be used: 1) Measure the specified distance and use a drilling tool to drill holes in the water pipe 1, then apply adhesive to the outer wall of the water pipe 1; 2) Place the two arc-shaped filter blocks 10 inside the cavities at the ends of the first outer shell 2 and the second outer shell 3; 3) Press the first outer shell 2 to allow the connecting tube 9 to enter the interior of the connecting hole 8, and then push the second outer shell 3 upward to engage the buckle 6 with the buckle block 7, so that the first outer shell 2 and the second outer shell 3 are fastened to the outer wall of the water pipe 1.

[0023] In summary, when the user uses the system, the first outer shell 2 and the second outer shell 3 are connected and fastened to the outer wall of the water supply pipe 1 by the snap fastener 6 and the locking block 7. This makes installation more convenient and facilitates on-site construction. The connecting pipe 9 enters the interior of the water supply pipe 1. The interior of the water outlet trough 11 is equipped with multiple arc-shaped elastic plates 13 and a sealing cover 4. The ends of the first outer shell 2 and the second outer shell 3 are provided with multiple water outlet holes 5, which facilitates the formation of a water outlet channel and enables efficient water supply to the external soil. When the underground drip irrigation system is shut down, the soil pressure or pipeline load... The pressure causes the ends of two adjacent arc-shaped elastic sheets 13 to bend and stack on each other, thus sealing the waterway. In conjunction with two arc-shaped filter blocks 10, it can effectively prevent mud, sand, and roots from entering and causing blockage. Then, through the first outer shell 2, a water outlet groove 11 is opened on its top surface. The water outlet groove 11 is connected to the connecting pipe 9 and the two cavities respectively, thereby forming a wider water outlet channel, which makes the whole has better anti-clogging performance and longer service life. The inner support frame 12 facilitates the support of the sealing cover 4 to resist the pressure of the external soil on the sealing cover 4 and prevent the sealing cover 4 from deforming.
