Description

Technical Field

[0001] The present invention relates to the technical field of pipeline laying, and specifically provides a guiding device for laying agricultural engineering irrigation pipelines that is convenient for adapting to terrain. Background Art

[0002] Irrigation is a technical measure to supplement the water required by crops in the field. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply sufficient water to the crops. Under natural conditions, due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, it is necessary to artificially irrigate to make up for the deficiency of natural rainfall. Pipelines can control the water flow rate. Due to differences in temperature, wind speed, soil, and infiltration capacity, surface irrigation is likely to cause the phenomenon of too much water in some places and insufficient water in other places. Pipelines can be moved, so this uneven phenomenon can be controlled; When the common guiding devices for laying agricultural engineering irrigation pipelines are in use, they lack intuitive angle markings and positioning tools, and rely on manual measurement or empirical judgment of the angles between adjacent guiding frames. The control deviation of the pipeline bend in the middle is large, which makes the pipeline prone to excessive bending, increasing the conveying resistance of the fluid inside the pipeline, and it is not convenient to adapt to different terrains, resulting in poor use effects of the guiding device when facing different terrains. For this reason, we propose a guiding device for laying agricultural engineering irrigation pipelines that is convenient for adapting to terrain. Summary of the Invention

[0019] Embodiment 1 A guiding device for laying agricultural engineering irrigation pipelines that is convenient for adapting to terrain. In agricultural irrigation projects, the terrain is complex and diverse, such as mountainous areas, hilly areas, wetland areas, or farmland areas with large slopes. Laying pipelines often faces severe challenges. Traditional pipeline laying guiding devices cannot flexibly adapt to changes in ground undulation or soil softness, resulting in problems such as pipelines being suspended, overly bent, or not firmly fixed during the laying process; Traditional guiding devices rely on manual measurement or empirical judgment of the angles between adjacent guiding frames, lacking intuitive angle marking and positioning tools. In complex terrains, the control deviation of the pipeline bending angle is relatively large, which not only increases the water flow resistance and reduces the irrigation efficiency, but may also cause pipeline rupture and water leakage due to stress concentration. In addition, traditional devices take a long time to adjust and need to frequently re-fix the positions of the guiding frames, resulting in an extended construction period; Therefore, in order to effectively solve the above problems, this application proposes a guiding device for laying agricultural engineering irrigation pipelines that is convenient for adapting to terrain, as shown in the accompanying drawings of the specification Figures 1-9As shown in the figure, it includes a guiding device main body 1.

At the same time, different square holes and circular holes are respectively formed in different lower indicating rods 27 and upper indicating rods 28. The lower indicating rods 27 and upper indicating rods 28 with the same number of holes correspond to each other. For example, when observing the angle between adjacent guiding frames 11, when there are two square holes in the viewed lower indicating rod 27, the corresponding upper indicating rod 28 with two circular holes needs to be viewed.

The first angle block 41 and the second angle block 42 can enable the lower connecting plate 25 and the upper connecting plate 26 to have a vertical angle adjustment function, so that the two adjacent guide frames 11 can be not on the same horizontal plane.

[0021] Embodiment 3 The supporting mechanism includes a cross mounting base 43 and mounting screws 44. A concave hole is provided at the lower end of the lower connecting plate 25. The inner wall of the concave hole is slidably connected to the outer wall of the cross mounting base 43. A supporting hole is provided at the lower end of the cross mounting base 43. A receiving hole is provided at the lower wall of the concave hole. The mounting screws 44 are spirally connected to the receiving hole through the supporting hole. A cross groove 47 is formed at the lower end of the lower convex cylinder 46, and the cross groove 47 cooperates with the cross mounting base 43; The observation mechanism 5 includes an upper column 54 and a lower column 55. A central hole 52 is provided in the middle of the lower end of the lower convex cylinder 46. An inner cavity 53 is provided at the upper end of the central hole 52.

When the upper connecting plate 26 rotates, it will synchronously drive the upper column 54 and the upper indicating rod 28 to rotate; Specifically, the cross-shaped mounting base frame 43 and the cross-shaped groove 47 can tightly connect the lower connecting plate 25 and the upper connecting plate 26. The central hole 52 is used to enable the lower column 55 and the lower indicating rod 27 to enter the inner cavity 53. The lower indicating rod 27 and the upper indicating rod 28 cooperate with each other. The upper column 54 and the lower column 55 are respectively connected to the upper connecting plate 26 and the lower connecting plate 25, so that when adjacent two guiding frames 11 are arranged, the angle between the two guiding frames 11 can be known in real time.

[0022] Working principle: First, arrange the buckling plate 31, the guiding frame 11 and the arc-shaped floor inserting plate 23 at the required positions, and insert the arc-shaped floor inserting plate 23 into the ground. At this time, adjust the positions of adjacent guiding frames 11 as needed. When adjusting the positions of adjacent guiding frames 11, the adjacent guiding frames 11 will drive the corresponding lower connecting plate 25 to rotate along the lower convex cylinder 46 of the upper connecting plate 26. At this time, the lower indicating rod 27 will be driven to rotate. At this time, the staff can view the lower indicating rod 27 and the upper indicating rod 28 through the annular observation port 51, and cooperate with the angle marking ring 29 to know the arrangement angle between adjacent two guiding frames 11. At the same time, the angle of adjacent two guiding frames 11 can also be determined according to the bending angle of the pipeline during arrangement. When it is necessary to adjust the height of the guiding frame 11, rotate the screw rod 24. Use the rotation of the screw rod 24 to make the lifting adaptor block 34 lift and lower, thereby driving the guiding frame 11 to lift and lower. At the same time, the screw rod 24 can be detached from the buckling plate 31 through the connecting rod 33. At this time, the screw rod 24 with different heights can be replaced. When the guiding laying of the pipeline is completed, arrange the pipeline on the guiding frame 11. At this time, rotate the guiding buckle plate 21 to make the guiding buckle plate 21 contact with the guiding frame 11, and use the fixing screw 211 to fix the guiding buckle plate 21 and the guiding frame 11, so as to limit the pipeline between the guiding frame 11 and the guiding buckle plate 21 and prevent the pipeline from displacing during use. Thus, the whole working process ends.
