Description

Technical Field

[0001] The present invention relates to the technical field of farmland irrigation and drainage systems, and specifically refers to a plug-and-play pipe structure for farmland inlet and outlet. Background Art

[0002] With global climate change and population growth, the challenges faced by agricultural production are becoming increasingly severe. In order to ensure food security and sustainable agricultural development, countries have been promoting the construction of high-standard farmland. High-standard farmland not only requires flat land and fertile soil, but also a complete irrigation and drainage system to cope with natural disasters such as droughts and floods. However, when the existing farmland irrigation and drainage systems are applied to high-standard farmland, there are still many deficiencies:

[0003] Fixed pipeline system: When the traditional fixed pipeline system is applied in high-standard farmland, it lacks flexibility and is difficult to adjust according to the water requirements of different plots. In addition, once the fixed pipeline is damaged, the repair cost is high and time-consuming, affecting the normal irrigation of farmland.

[0004] Open-channel drainage system: Although the construction cost of open channels is low, there is a serious problem of water resource waste, especially in areas with water shortages. In addition, open channels are prone to soil erosion and water pollution, which is not conducive to the ecological environment protection of high-standard farmland.

[0005] To solve the above problems, some improved farmland irrigation and drainage systems have emerged in recent years. For example, the adjustable pipeline system can achieve partial control of water flow by setting valves or gates on the pipeline. However, these systems still have some deficiencies:

[0006] Complex operation: The operation of valves or gates usually requires professional tools and manpower, increasing the complexity and cost of operation.

[0007] Poor sealing: Valves or gates are prone to wear and aging during long-term use, resulting in a decline in sealing performance and serious water leakage problems.

[0008] Complex structure: The complex mechanical structure not only increases the manufacturing cost of the system, but also reduces the reliability and durability of the system.

[0009] Therefore, a plug-and-play pipe structure for farmland inlet and outlet is proposed to solve the existing deficiencies. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a plug-and-play pipe structure for farmland inlet and outlet.

[0011] To solve the above technical problem, the technical solution provided by the present invention is a plug-and-play pipe structure for farmland inlet and outlet: including an elbow pipe and a plug-and-play pipe;

[0012] One end of the elbow pipe is connected to the water delivery pipe, and the other end of the elbow pipe is coaxially connected with an adapter pipe;

[0013] One end of the plug-in pipe is movably inserted into the adapter pipe. A sealing ring cooperating with the adapter pipe is sleeved on the plug-in pipe, and a limiting ring cooperating with the sealing ring is fixedly sleeved on the plug-in pipe.

[0014] As an improvement, the adapter pipe and the elbow pipe are fixedly connected by hot melting.

[0015] As an improvement, the plug-in pipe and the adapter pipe are coaxially arranged, and the outer diameter of the plug-in pipe is adapted to the inner diameter of the adapter pipe.

[0016] As an improvement, the plug-in pipe and the adapter pipe overlap for a certain length.

[0017] As an improvement, the sealing ring and the plug-in pipe are in interference fit. A first annular notch cooperating with the end of the adapter pipe is arranged at the bottom of the sealing ring, and a second annular notch cooperating with the end of the limiting ring is arranged at the top of the sealing ring.

[0018] As an improvement, the sealing ring is made of rubber.

[0019] As an improvement, the limiting ring is fixedly connected to the plug-in pipe by a pin.

[0020] As an improvement, the elbow pipe is of a 90° elbow structure.

[0021] As an improvement, the elbow pipe, the adapter pipe and the plug-in pipe are all made of polyethylene material.

[0022] The advantages of the present invention compared with the prior art are as follows:

[0023] 1. Through the interference fit between the sealing ring and the plug-in pipe and the fixed connection of the limiting ring, the fixed setting of the sealing ring on the plug-in pipe is ensured. The sealing ring is made of rubber material, which has good elasticity and sealing performance, can effectively fill the gap between the plug-in pipe and the adapter pipe, prevent water leakage, and ensure the effective utilization of water resources and the normal irrigation of farmland.

[0024] 2. The control of water blocking and water discharging of water flow can be realized through simple plugging and unplugging operations. The design of the plug-in pipe makes the operation process intuitive and easy to master, without the need for professional tools or complex technical knowledge, reduces the operation difficulty and labor cost, can quickly respond to the irrigation and drainage needs of farmland, and improves work efficiency.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0033] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the component is required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0034] In the description of the embodiments of the present invention, "a plurality" represents at least 2.

[0035] In the description of the embodiments of the invention, it should also be noted that unless otherwise clearly specified and limited, if the terms "set", "installed", "connected", and "coupled" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0036] As shown in the accompanying drawings, a plug-and-play pipe structure for farmland inlets and outlets is provided. This structure is a plug-and-play pipe structure for farmland inlets and outlets in high-standard farmland. By inserting and removing the plug-and-play pipe 2 and controlling the insertion and removal operations of the plug-and-play pipe, the functions of blocking and discharging water in the farmland are realized, thereby effectively managing the irrigation and drainage of the farmland.

[0037] This structure includes an elbow pipe 1 and a plug-and-play pipe 2;

[0038] One end of the elbow pipe 1 is connected to the water delivery pipe. The elbow pipe 1 serves as the starting end of the entire plug-and-play pipe structure for inlets and outlets, forming a water flow diversion channel and playing a role in guiding the change of the water flow direction.

[0039] Specifically, the angle of the elbow pipe 1 can be set according to the actual situation. In order to meet the requirements in the complex terrain of farmland, the angle adjustment of the elbow pipe 1 can better adapt to the terrain changes and ensure that the water flow can be smoothly discharged from the farmland. In this embodiment, the elbow pipe 1 is a 90° elbow structure.

[0040] The other end of the elbow pipe 1 is coaxially connected with an adapter pipe 3. The adapter pipe 3 and the elbow pipe 1 are fixedly connected by a hot-melt method, ensuring the sealing performance and structural stability of the connection, so that the water flow can smoothly transition from the elbow pipe 1 to the adapter pipe 3.

[0041] In this embodiment, the adapter pipe 3 is an extension of the elbow pipe 1, and the two are fixed by a hot-melt method to form a continuous water flow channel. At the same time, the adapter pipe 3 provides an interface for the plug-and-play pipe 2 to be inserted and removed, thereby realizing the functions of blocking and discharging water.

[0042] One end of the plug-and-play pipe 2 is movably inserted into the adapter pipe 3. The plug-and-play pipe 2 and the adapter pipe 3 are coaxially arranged. The outer diameter of the plug-and-play pipe 2 is adapted to the inner diameter of the adapter pipe 3, ensuring that the plug-and-play pipe 2 can be smoothly inserted and removed in the adapter pipe 3, and to a certain extent guaranteeing the basic sealing performance at the connection between the plug-and-play pipe 2 and the adapter pipe 3, preventing water leakage when the water discharge operation is not carried out.

[0043] With the arrangement of the plug-in tube 2, the entire plug-in tube structure of the water inlet and outlet has flexible control ability and can be operated according to the actual water demand of the farmland.

[0044] Furthermore, the plug-in tube 2 overlaps with the connecting tube 3 for a certain length, which not only helps to improve the sealing effect but also prevents the plug-in tube 2 from moving excessively or tilting within the connecting tube 3, thus ensuring the reliability and durability of the entire plug-in tube structure of the water inlet and outlet during use.

[0045] During implementation, the flow of water is controlled by the plugging and unplugging actions of the plug-in tube 2. When the plug-in tube 2 is inserted into the connecting tube 3, the flow of water is blocked; when the plug-in tube 2 is pulled out, the water can flow out from the connecting tube 3.

[0046] A sealing ring 4 that cooperates with the connecting tube 3 is sleeved on the plug-in tube 2, which can effectively fill the gap between the plug-in tube 2 and the connecting tube 3, ensuring that water does not seep out from the connection in the water-blocking state.

[0047] The sealing ring 4 and the plug-in tube 2 are in interference fit to ensure the stability of the sealing ring 4 on the plug-in tube 2, preventing it from falling off or shifting during use and further enhancing the sealing effect.

[0048] A limiting ring 5 that cooperates with the sealing ring 4 is fixedly sleeved on the plug-in tube 2. The limiting ring 5 is fixedly connected to the plug-in tube 2 through a pin 8 to limit and fix the sealing ring 4, preventing it from moving excessively during the plugging and unplugging process.

[0049] Specifically, a first annular notch 6 that cooperates with the end of the connecting tube 3 is provided at the bottom of the sealing ring 4, enabling the sealing ring 4 to closely fit with the end of the connecting tube 3 to form a reliable seal.

[0050] A second annular notch 7 that cooperates with the end of the limiting ring 5 is provided at the top of the sealing ring 4. Through the second annular notch 7, the cooperation between the limiting ring 5 and the sealing ring 4 can be ensured to ensure the fixation of the sealing ring 4 on the plug-in tube 2.

[0051] In this embodiment, the sealing ring 4 is made of rubber. When in use, the sealing ring 4 can undergo elastic deformation when subjected to water pressure, filling all the tiny gaps between the plug-in tube 2 and the connecting tube 3 to ensure the integrity of the seal.

[0052] At the same time, even during frequent plugging and unplugging operations, the rubber sealing ring 4 can maintain its shape and sealing performance through its self-recovery ability, without losing elasticity due to repeated deformation; moreover, it can adapt to different temperature and humidity conditions to ensure reliable sealing in various farmland environments.

[0053] During implementation, when the plug-and-play pipe 2 is inserted into the connecting pipe 3, the sealing ring 4 can cooperate with the end of the connecting pipe 3 to play a good sealing role and prevent water from seeping out through the gap. The limiting ring 5 is fixedly connected to the plug-and-play pipe 2 through the pin 8, which plays a role in limiting and fixing the sealing ring 4, further enhancing the sealing effect, and at the same time restricting the excessive movement of the plug-and-play pipe 2 during use to ensure the stability of the structure.

[0054] When the present invention is specifically implemented, when it is necessary to prevent water from flowing in and out of the farmland, the plug-and-play pipe 2 is inserted into the connecting pipe 3. At this time, the sealing ring 4 fits with the end of the connecting pipe 3 to seal the port of the connecting pipe 3, so that water cannot flow out of the farmland through the connecting pipe 3, thereby realizing the function of water blocking. Since the sealing ring is made of rubber, it has good elasticity and sealing performance, and can effectively fill the gap between the plug-and-play pipe 2 and the connecting pipe 3 to further ensure the water blocking effect.

[0055] When the farmland needs to release water, just pull out the plug-and-play pipe 2 from the connecting pipe 3. At this time, the port of the connecting pipe 3 is in an open state, and water can flow out of the farmland along the elbow pipe 1 and the connecting pipe 3 to realize the function of water release. Moreover, because the plug-and-play pipe can be flexibly inserted and pulled out, the operation is convenient, and the start and end of water release can be controlled in time according to the actual water demand of the farmland.

[0056] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
