Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically to a self-regulating pipeline connector for farmland irrigation that adapts to different terrains. Background Technology

[0002] The background of this paper focuses on the technology of self-regulating irrigation pipe connectors adapted to different terrains, primarily addressing how to efficiently and stably provide irrigation water to farmland under various terrain conditions. With the advancement of agricultural modernization and intelligentization, traditional irrigation systems face many challenges, such as difficult pipe laying, long construction periods, low irrigation efficiency, and difficult maintenance. Therefore, developing irrigation pipe connectors adapted to different terrains is an important direction for improving the reliability and flexibility of irrigation systems.

[0003] Patent specification CN102187140A discloses a self-regulating irrigation pipe connector for farmland adapted to different terrains. The connector body has at least one connecting end, and each connecting end includes: a wall defining a receiving groove for receiving one end of a pipe segment; a groove of a certain depth formed on the inner surface of the wall of the receiving groove; and a channel connecting the groove and the outer surface of the connecting end. The pipe connector further includes: a connecting member formed of a piece of material, which is inserted into the groove via the channel. The thickness of the connecting member is greater than the depth of the groove, and when inserted into the groove, the connecting member extends into the receiving groove.

[0004] However, in implementing the relevant technology, the above-mentioned self-regulating pipeline connector for farmland irrigation adapted to different terrains has the following problems: the device uses a rotating bolt to drive the squeezing block to move down and clamp and fix one end of the pipeline, which is inconvenient to operate, and the outer wall of the pipeline may be squeezed and deformed. The pipeline cannot rotate flexibly, which affects irrigation, and it cannot reduce the impact force of water flow. Therefore, we have proposed a self-regulating pipeline connector for farmland irrigation adapted to different terrains. Utility Model Content

[0005] This utility model proposes a self-regulating pipeline connector for farmland irrigation that adapts to different terrains, solving the problems of inconvenient pipeline installation, inflexible connector rotation, and inability to reduce the impact force of internal water flow in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] A self-regulating irrigation pipe connector for farmland adaptable to different terrains includes a main pipe, a deflector joint, and a first spring. The outer wall of the main pipe is provided with a compression block, and a sliding sleeve is movably installed on the outer wall of the main pipe. The outer wall of the compression block is connected to the first spring. The inner wall of the sliding sleeve is provided with a limit block, which is connected to the other end of the first spring. The first spring is located on the outer wall of the main pipe. One end of the outer wall of the main pipe is uniformly provided with mounting grooves. A connecting universal ball is movably installed on the inner wall of the mounting groove. The inner wall of the main pipe is movably connected to the deflector joint via the connecting universal ball. One end of the deflector joint is provided with a connector body, and the outer wall of the connector body is provided with a retaining groove.

[0008] Preferably, the main pipeline is provided with multiple sets of buffer blocks, each buffer block having a groove on its inner wall, a force-bearing block being movably mounted on the buffer block through the groove, and a slider being provided at one end of the force-bearing block.

[0009] Preferably, a second spring is installed on the inner wall of the slide, and one end of the second spring is connected to the outer wall of the slider.

[0010] Preferably, the slider has an annular block structure, and the slider and the groove fit together.

[0011] Preferably, a through hole is provided at the center of the force-bearing block, and the outer wall of the force-bearing block has a conical structure.

[0012] Preferably, the slot has an annular groove structure, and the connecting universal ball fits into the slot.

[0013] Preferably, the outer wall of the main pipe and the inner wall of the first spring have movable grooves, and the outer wall of the first spring is provided with anti-slip texture.

[0014] Preferably, the limiting block has a ring-shaped structure and is located on the periphery of the mounting groove.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, a compression block, a first spring, and a limiting block are used to manually press the sliding sleeve to make it slide along the outer wall of the main pipe. During the sliding process, the side wall of the limiting block cooperates with the compression block to compress the first spring, causing the limiting block to stop limiting the connecting universal ball and allowing it to move within the inner wall of the mounting groove. The connector body at the front end of the swivel joint is inserted into the inner wall of the main pipe. After the main pipe and the swivel joint are engaged, the connecting universal ball is located outside the groove. Releasing the sliding sleeve utilizes the elastic force generated by the deformation of the first spring to reset the sliding sleeve, causing the limiting block to return to the side wall of the mounting groove and limit the connecting universal ball, so that a part of the connecting universal ball is evenly located inside the groove. The connection between the main pipe and the swivel joint is completed by engaging the connecting universal ball with the groove. Since the connecting universal ball is spherical and the groove is an annular groove structure, the swivel joint can be rotated freely to adjust the water flow angle for irrigation of farmland with different terrains. This structure is easy to connect and allows for free adjustment of the angle of the swivel joint to change the water flow direction, facilitating irrigation.

[0017] In this invention, the main pipe, the force-bearing block, and the second spring are configured so that when water flows through the inner wall of the main pipe, it impacts the force-bearing block. When the water impacts the force-bearing block, the conical outer wall of the force-bearing block maximizes the contact area with the water flow, absorbing its impact force and dispersing it evenly. When the force-bearing block is subjected to impact force, it drives the slider to compress the second spring along the inner wall of the groove. The elastic force generated by the deformation of the second spring continuously counteracts the impact force of the water flow. Multiple sets of buffer blocks set on the inner wall of the main pipe continuously reduce the impact force of the water flow, thereby preventing the water flow from having too great an impact force when it flows through the corner of the turning joint, which would affect the connection integrity of the main pipe and the turning joint. This structure can continuously reduce the impact force of the water flow during use, preventing the water pipe from breaking due to excessive impact force of the water flow in the pipe.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: As Figures 1-5 As shown, this embodiment proposes a self-adjusting pipeline connector for farmland irrigation that adapts to different terrains, including a main pipeline 1, a deflector 3, and a first spring 5. The outer wall of the main pipeline 1 is provided with a compression block 4, and a sliding sleeve 2 is movably installed on the outer wall of the main pipeline 1. The outer wall of the compression block 4 is connected to the first spring 5. The inner wall of the sliding sleeve 2 is provided with a limit block 6, which is connected to the other end of the first spring 5. The first spring 5 is located on the outer wall of the main pipeline 1. The outer wall of one end of the main pipeline 1 is uniformly provided with an installation groove 7, and a connecting universal ball 8 is movably installed on the inner wall of the installation groove 7. The inner wall of the main pipeline 1 is movably connected to the deflector 3 through the connecting universal ball 8. One end of the deflector 3 is provided with a connector body 11, and the outer wall of the connector body 11 is provided with a slot 10.

[0027] In this embodiment, the slot 10 has an annular groove structure, and the universal ball 8 and the slot 10 fit together.

[0028] In this embodiment, the outer wall of the main pipe 1 and the inner wall of the first spring 5 have movable grooves, and the outer wall of the first spring 5 is provided with anti-slip texture.

[0029] In this embodiment, the limiting block 6 has a ring-shaped structure and is located on the periphery of the mounting groove 7.

[0030] Specific examples Figure 1 , Figure 3 and Figure 4As shown, when using this structure, manually press the sliding sleeve 2 to make it slide along the outer wall of the main pipe 1. During the sliding process, the side wall of the limiting block 6 will cooperate with the pressing block 4 to press the first spring 5, so that the limiting block 6 stops limiting the connecting universal ball 8 and allows it to move on the inner wall of the mounting groove 7. Insert the connector body 11 set at the front end of the deflector 3 into the inner wall of the main pipe 1. After the main pipe 1 and the deflector 3 are engaged and connected, the connecting universal ball 8 is located on the outer periphery of the groove 10. Release the sliding sleeve 2 and use the elastic force generated by the deformation of the first spring 5 to make the sliding sleeve 2 move along the outer wall of the main pipe 1. Set 2 is reset, so that the limiting block 6 is reset to the side wall of the mounting groove 7, limiting the connecting universal ball 8, so that a part of the connecting universal ball 8 is evenly located inside the slot 10. The connection of the main pipe 1 and the deflector 3 is completed by the connection of the connecting universal ball 8 and the slot 10. Since the connecting universal ball 8 is spherical and the slot 10 is an annular groove structure, the deflector 3 can be rotated freely to adjust the water flow angle for irrigation of farmland with different terrains. This structure is easy to connect and the angle of the deflector 3 can be freely adjusted to change the water flow direction for convenient irrigation.

[0031] Example 2: The main pipe 1 is provided with multiple sets of buffer blocks 9. The inner wall of each buffer block 9 is provided with a sliding groove 13. A force-bearing block 12 is movably installed on the buffer block 9 through the sliding groove 13. A slider 14 is provided at one end of the force-bearing block 12.

[0032] In this embodiment, a second spring 15 is installed on the inner wall of the slide groove 13, and one end of the second spring 15 is connected to the outer wall of the slider 14.

[0033] In this embodiment, the slider 14 has an annular block structure, and the slider 14 and the groove 13 fit together.

[0034] In this embodiment, a through hole is provided at the center of the force-bearing block 12, and the outer wall of the force-bearing block 12 has a conical structure.

[0035] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, when using this structure, the water flow will impact the force-bearing block 12 when it flows through the inner wall of the main pipe 1. When the water flow impacts the force-bearing block 12, the outer wall of the force-bearing block 12 is conical, which will maximize the contact area with the water flow to absorb its impact force and distribute it evenly. When the force-bearing block 12 is subjected to impact force, it will drive the slider 14 to compress the second spring 15 along the inner wall of the slide groove 13. The elastic force generated by the deformation of the second spring 15 will continuously offset the impact force of the water flow. The multiple sets of buffer blocks 9 set on the inner wall of the main pipe 1 will continuously reduce the impact force of the water flow, thereby avoiding the water flow from having too large an impact force when it flows through the corner of the diversion joint 3, which would affect the connection integrity of the main pipe 1 and the diversion joint 3. This structure can continuously reduce the impact force of the water flow during use, and prevent the water pipe from breaking due to excessive impact force of the water flow in the pipe.

[0036] Working principle: Manually press the sliding sleeve 2 to make it slide along the outer wall of the main pipe 1. During the sliding process, the side wall of the limiting block 6 will cooperate with the squeezing block 4 to squeeze the first spring 5, so that the limiting block 6 stops limiting the connecting universal ball 8 and allows it to move on the inner wall of the mounting groove 7. Insert the connector body 11 at the front end of the diverter 3 into the inner wall of the main pipe 1. After the main pipe 1 and the diverter 3 are engaged, the connecting universal ball 8 is located on the outer periphery of the groove 10. Release the sliding sleeve 2 and use the elastic force generated by the deformation of the first spring 5 to reset the sliding sleeve 2, so that the limiting block 6 returns to the side wall of the mounting groove 7 and limits the connecting universal ball 8, so that a part of the connecting universal ball 8 is evenly located inside the groove 10. The connection of the main pipe 1 and the diverter 3 is completed by the engagement of the connecting universal ball 8 and the groove 10. Since the connecting universal ball 8 is spherical and the groove 10 is an annular groove structure, the diverter 3 can be rotated freely to adjust the water flow angle. This device facilitates irrigation of farmland in various terrains. When water flows through the inner wall of the main pipe 1, it impacts the force-bearing block 12. The cone-shaped outer wall of the force-bearing block 12 maximizes its contact area with the water flow, absorbing and evenly dispersing the impact. When the force-bearing block 12 experiences impact, it drives the slider 14, causing it to compress the second spring 15 along the inner wall of the slide groove 13. The elastic force generated by the deformation of the second spring 15 continuously counteracts the impact of the water flow. Multiple sets of buffer blocks 9 installed on the inner wall of the main pipe 1 continuously reduce the impact of the water flow, thus preventing excessive impact at the corner of the turning joint 3, which could affect the connection between the main pipe 1 and the turning joint 3. This device is easy to connect and allows for free adjustment of the angle of the turning joint 3 to change the direction of water flow, facilitating irrigation. It also continuously reduces the impact of the water flow, preventing excessive impact from causing pipe breakage.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
