[0002] High-standard farmland irrigation refers to the efficient use of farmland water and the precise supply of water required for crop growth through the use of modern irrigation technology and management methods in the construction of high-standard farmland. The culvert refers to the pipeline part of the irrigation system used in the construction of high-standard farmland. The culvert transports water to every corner of the farmland through the pipeline. In summary, the problems existing in the prior art are: when laying the culvert, it is necessary to open a corresponding pipe pit on the land surface, and then the culvert is connected and placed inside the pipe pit. When connecting the culvert, various methods such as threaded connection, hot melt connection, electric fusion connection and flange connection can be used. Impurities are easily accumulated at the corners of the culvert connection, and long-term use requires dredging to prevent blockage.

DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a high-standard culvert connection structure for farmland irrigation provided by an embodiment of the utility model includes two culverts 1 and a transfer tube 2. The rear side of the culvert 1 is fixedly connected to the front side of the transfer tube 2. Two docking shells 3 are fixedly connected to the surface of the transfer tube 2. A docking tube 4 used in conjunction with the docking shell 3 is fixedly connected to the surface of the culvert 1. The surface of the docking tube 4 is in contact with the inner cavity of the docking shell 3. The inner cavity of the docking shell 3 is movably connected with a control dial 5. The bottom of the control dial 5 passes through the docking shell 3 and extends to the outside of the inner cavity of the docking shell 3. A fixing device 6 is arranged inside the docking shell 3.

[0022] refer to Figure 3 The fixing device 6 includes four fixing blocks 601. The side of the fixing block 601 close to the culvert 1 passes through the docking shell 3 and extends to the outside of the inner cavity of the docking shell 3. The side of the fixing block 601 away from the culvert 1 is fixedly connected to two positioning rods 602. The surface of the positioning rod 602 is sleeved with a spring 603. The side of the spring 603 close to the culvert 1 is fixedly connected to the surface of the fixing block 601.

[0023] By adopting the above solution, by providing the fixing device 6 , when the culvert 1 moves to the position connected with the transfer tube 2 , the fixing device 6 has a limiting effect on the position of the culvert 1 .

[0024] refer to Figure 3 The inner cavity of the docking shell 3 is fixedly connected with four positioning shells 7 used in conjunction with the positioning rod 602. The surface of the positioning rod 602 is movably connected to the inner cavity of the positioning shell 7. The side of the spring 603 away from the culvert 1 is fixedly connected to the surface of the positioning shell 7.

[0025] The above solution is adopted: by setting the positioning shell 7, when the fixed block 601 moves, it will drive the positioning rod 602 to move along the inner cavity of the positioning shell 7. The coordinated use of the positioning shell 7 and the positioning rod 602 has a limiting effect on the moving position of the fixed block 601.

[0026] refer to Figure 3 A side of the fixed block 601 close to the control dial 5 is fixedly connected to a squeezing rod 8, and a surface of the control dial 5 is fixedly connected to four squeezing frames 9 used in conjunction with the squeezing rod 8, and the inner cavity of the squeezing frame 9 contacts the surface of the squeezing rod 8.

[0027] The above solution is adopted: by setting the extrusion rod 8 and the extrusion frame 9, when the control dial 5 rotates, the extrusion frame 9 will be driven to rotate along the surface of the extrusion rod 8. The extrusion frame 9 can generate an extrusion force on the extrusion rod 8, and the extrusion rod 8 subjected to the extrusion force can drive the fixed block 601 to move.

[0028] refer to Figure 4 The inner cavity of the control turntable 5 is fixedly connected with two sliding blocks 10, the inner cavity of the docking shell 3 is fixedly connected with a sliding shell 11 used in conjunction with the sliding blocks 10, and the surface of the sliding block 10 is movably connected to the inner cavity of the sliding shell 11.

[0029] The above solution is adopted: by setting the sliding block 10 and the sliding shell 11, when the control dial 5 rotates, the sliding block 10 will be driven to rotate along the inner cavity of the sliding shell 11. The coordinated use of the sliding block 10 and the sliding shell 11 has a limiting effect on the rotation position of the control dial 5.

[0030] refer to Figure 2 A fixing slot 12 for use with the fixing block 601 is provided on the surface of the butt joint 4 , and the surface of the fixing block 601 contacts the inner cavity of the fixing slot 12 .

[0031] The above scheme is adopted: by setting a fixed card slot 12, when the docking tube 4 moves to the inner cavity of the docking shell 3, the control dial 5 is released, and the restoring force generated by the spring 603 restoring its shape will drive the fixed card block 601 to be stuck into the inner cavity of the fixed card slot 12. The coordinated use of the fixed card block 601 and the fixed card slot 12 has a limiting effect on the position of the docking tube 4.

[0032] refer to Figure 2 A sealing sleeve 13 is fixedly connected to the rear side of the culvert 1 , and a sealing groove 14 for use with the sealing sleeve 13 is provided in the inner cavity of the docking shell 3 , and the surface of the sealing sleeve 13 contacts the inner cavity of the sealing groove 14 .

[0033] The above solution is adopted: by providing the sealing sleeve 13 and the sealing groove 14, the sealing sleeve 13 and the sealing groove 14 are used in combination to increase the sealing performance of the connection between the culvert 1 and the transfer tube 2, effectively preventing water leakage.

[0034] The working principle of this utility model:

[0035] When in use, when the corner of the culvert 1 used for high-standard agricultural irrigation needs to be easily disassembled for maintenance, the user first rotates the control dial 5 toward the top. When the control dial 5 rotates, it will drive the extrusion frame 9 to rotate along the surface of the extrusion rod 8. The extrusion force generated by the extrusion frame 9 on the extrusion rod 8 can drive the extrusion rod 8 to move to the side away from the culvert 1. When the extrusion rod 8 moves, it will drive the fixed block 601 to move to the side away from the culvert 1. When the fixed block 601 moves, it will drive the positioning rod 602 to move along the inner cavity of the positioning shell 7. At the same time, the force generated causes the spring 603 to undergo elastic deformation. When the fixed block 601 is completely moved to the inner cavity of the docking shell 3, , the docking tube 4 can be moved out of the inner cavity of the docking shell 3, and at the same time, the sealing sleeve 13 can be moved out of the inner cavity of the sealing groove 14, and the culvert 1 can be separated from the contact with the transfer tube 2. At this time, the culvert 1 is completely disassembled and can be maintained. After the maintenance is completed, the docking tube 4 is moved to the inner cavity of the docking shell 3, and at the same time, the sealing sleeve 13 is driven to move to the inner cavity of the sealing groove 14, and then the control dial 5 is released. The restoring force generated by the spring 603 restoring its shape will drive the fixed block 601 to be stuck into the inner cavity of the fixed groove. The coordinated use of the fixed block 601 and the fixed groove has a limiting effect on the position of the culvert 1. At this time, the culvert 1 used for high-standard agricultural irrigation can be conveniently disassembled at the corner for maintenance.

[0036] In summary: the high-standard farmland irrigation culvert connection structure, by setting a fixing device 6, a fixing block 601, a positioning rod 602, a spring 603 and a fixing slot 12 for coordinated use, solves the problem that when laying existing culverts, a corresponding pipe pit needs to be opened on the ground surface, and then the culvert is connected and placed inside the pipe pit. The culvert can be connected in a variety of ways such as threaded connection, hot-melt connection, electric-melt connection and flange connection. Impurities are easily accumulated at the corners of the culvert connection, and long-term use requires dredging to prevent blockage. The existing connection method takes a long time to disassemble and is not convenient enough. In addition, the hot-melt connection, electric-melt connection and other methods make it impossible to disassemble and dredge the culvert, causing the culvert to be blocked and affecting its use. However, the existing culvert corner connection structure used in high-standard agricultural irrigation cannot be conveniently disassembled for maintenance.
