Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a diversion irrigation pipe for water conservancy projects. Background Technology
[0002] Agricultural irrigation is an important part of water conservancy projects. Given my country's vast land area, irrigation pipelines are essential for large-scale irrigation. For large-scale irrigation, rigid irrigation pipelines are typically laid to form an irrigation network to ensure long-term durability and uninterrupted irrigation. However, this approach is suitable for large areas of farmland that remain relatively unchanged for extended periods. Once the farmland changes—for example, with variations in the size and location of plots or changes in crops—the route of the irrigation pipelines sometimes needs to be adjusted accordingly. In such cases, for traditional rigid pipeline networks, changing the irrigation route requires reconnecting the pipelines, which is difficult, time-consuming, and labor-intensive. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a diversion irrigation pipe for water conservancy projects, which can more conveniently change the irrigation direction after the irrigation pipe is laid, saving time and effort.
[0004] The technical solution adopted by this utility model is as follows: a diversion irrigation pipe for water conservancy projects is provided, including multiple main pipes arranged in sequence; the multiple main pipes are connected to each other by connecting pipes; the connecting pipes are foldable telescopic pipe structures; the side of the main pipes is integrally connected with a transition interface; a flow control component is provided at the transition interface.
[0005] The flow control assembly includes a sealing cover threaded to the outside of the adapter; a sliding plug is provided inside the sealing cover; the sliding plug is correspondingly and slidably inserted into the adapter; a positioning screw is coaxially provided on the sliding plug; the positioning screw is rotatably connected to the sliding plug, and the threaded seal passes through the outer end of the sealing cover; the threaded connection between the positioning screw and the sealing cover is used to adjust the depth of the sliding plug extending into the main tube through the adapter.
[0006] To further optimize this technical solution, a limiting sleeve is provided on the outer casing of a diversion irrigation pipeline for water conservancy projects; the two ends of the limiting sleeve are respectively threaded to the main body pipes on both sides of the diversion pipe.
[0007] To further optimize this technical solution, a sealing ring is fixedly fitted onto the inner wall of a sealing cover for a water diversion irrigation pipeline used in water conservancy projects; the sealing ring is used to abut and seal against the outer end of the adapter.
[0008] To further optimize this technical solution, a positioning hole seat is integrally connected to the outer wall of the main pipe of a water diversion irrigation pipeline for water conservancy projects.
[0009] The beneficial effects of this utility model are as follows:
[0010] By utilizing the connecting pipe of the folded telescopic pipe structure, the traditional rigid connection between the main pipes can be transformed into a flexible connection. When adjusting the irrigation direction of the irrigation network, the flexible bending of the connecting pipe can be used, eliminating the need to reconnect the pipes and greatly saving time and labor costs.
[0011] By adjusting the depth of the sliding plug inserted into the main pipe by screwing the positioning screw and the sealing cover, the range of the open diameter inside the main pipe can be changed, thereby adjusting the required water flow rate inside the main pipe and improving the flexibility of irrigation drainage.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] like Figure 1 As shown, a water diversion irrigation pipeline for water conservancy projects includes multiple main pipes 1 arranged in sequence; the multiple main pipes 1 are connected to each other by connecting pipes 2; the connecting pipes 2 are foldable telescopic pipe structures; the side of the main pipe 1 is integrally connected with an interface 3; a flow control component is provided at the interface 3;
[0017] like Figure 1 As shown, the flow control assembly includes a sealing cover 4 threadedly connected to the outside of the adapter 3; a sliding plug 5 is provided inside the sealing cover 4; the sliding plug 5 is correspondingly and slidably inserted into the adapter 3; a positioning screw 6 is coaxially provided on the sliding plug 5; the positioning screw 6 is rotatably connected to the sliding plug 5, and the threaded seal passes through the outer end of the sealing cover 4; the threaded connection between the positioning screw 6 and the sealing cover 4 is used to adjust the depth of the sliding plug 5 extending into the main tube 1 through the adapter 3.
[0018] like Figure 2 As shown, when it is necessary to adjust the direction of the irrigation pipeline, this application does not require a large-scale reconstruction of the irrigation network. It only requires the flexible bending effect of the connecting pipe 2 to make a slight adjustment to the direction of the main pipe 1 at the appropriate position, and the corresponding water outlet direction can be easily adjusted.
[0019] In the above process, the area used to adjust the direction of water flow is generally located in the downstream part of the irrigation network, and the water flow rate is not very large, so the durability of the flexible connecting pipe 2 under the impact of water flow can be guaranteed.
[0020] In addition, traditional methods of controlling water flow usually only involve installing valves at the outlet port for adjustment. This results in excessive stress concentration at the outlet port, making the area less durable and prone to cracking and breakage.
[0021] In this solution, a flow control component can be connected to each main pipe 1, distributing the traditional flow regulation process, which is only at the outlet port, to flow adjustment within multiple main pipes 1. This disperses the concentrated stress, avoiding the problem of easy cracking and damage at the outlet port, and improving the overall durability of the irrigation network. Specifically, by turning the positioning screw 6, the depth of the sliding plug 5 inside the main pipe 1 can be adjusted. The insertion of the sliding plug 5 into the main pipe 1 changes the open diameter range of the main pipe 1, thereby adjusting the flow rate.
[0022] like Figure 1-2 As shown, on the main pipe 1, which does not require the installation of a flow regulation component, the adapter 3 can be sealed by screwing the corresponding sealing cap 10 onto the adapter 3.
[0023] like Figure 1 As shown, the connecting pipe 2 is covered with a limiting sleeve 7; the two ends of the limiting sleeve 7 are threadedly connected to the main pipe 1 on both sides of the connecting pipe 2.
[0024] The limiting sleeve 7 can limit the connecting pipe 2 by connecting the two main body pipes 1, thus achieving a rigid connection between adjacent main body pipes 1. This method improves connection strength in areas where the drainage direction does not need to be changed. Of course, if... Figure 2 As shown, when the flexible connection effect of the connecting tube 2 is needed, the limiting sleeve 7 can be adjusted to connect only to one side of the main tube 1.
[0025] like Figure 1-2 As shown, a sealing ring 8 is fixedly fitted onto the inner wall of the sealing cover 4; the sealing ring 8 is used to abut against the outer end of the adapter 3 for sealing. The sealing ring 8 has two functions: first, it serves as a positioning device, indicating that the sealing cover 4 has been installed in place by being blocked by the adapter 3; second, by abutting against the adapter 3, it improves the sealing performance of the connection between the sealing cover 4 and the adapter 3, preventing water leakage at this point.
[0026] like Figure 2 As shown, a positioning hole seat 9 is integrally connected to the outer wall of the main tube 1. The positioning hole seat 9 allows for easy insertion of fasteners such as bolts and ground nails, and facilitates the fixing of the main tube 1 to the ground after the orientation of the main tube 1 is changed.
