Description

Technical Field

[0001] The utility model relates to the field of irrigation, in particular to a saline-alkali land irrigation system. Background Art

[0002] Saline-alkali land is a type of land where salts accumulate. It has a high salt content or alkalinity, poor soil structure, easy to compact, low organic matter content, poor nutrients, and weak soil fertilizer retention capacity, which affects crop growth. Due to the high salt content and high alkalinity, the humus in the lower part is easily lost after irrigation. The existing irrigation system usually arranges irrigation pipes in saline-alkali land, sets water outlets at multiple positions of the irrigation pipes, and simultaneously floods different positions. However, the positions of multiple water outlets are mostly fixed, and the water output is large, mostly in the form of flooding. Although the salt can be leached to a certain extent, it is easy to over-irrigate the soil near the water outlet, causing the groundwater level in the area to rise, aggravating the degree of salinity, and causing nutrient loss. The irrigation effect is not uniform, resulting in uneven distribution of soil salt, reducing irrigation efficiency, and increasing the difficulty and cost of improving soil salinization.

[0025] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0026] Example

[0027] As mentioned in the background technology, saline-alkali land needs to be irrigated during use and transformation, and the existing saline-alkali irrigation system has major defects. Although the setting of multiple water outlets can meet the effect of simultaneous irrigation at multiple locations, the fixed flooding will cause over-irrigation of the water outlet position, which will aggravate the salinity of the main area, the irrigation effect is not uniform, and the irrigation efficiency is low. Therefore, the inventor has improved the existing irrigation technology and designed a new irrigation system, which is explained in detail below with reference to the diagram.

[0028] This embodiment provides a saline-alkali land irrigation system. Figure 1 , including multiple irrigation pipe groups 1 arranged at intervals horizontally. The number of irrigation pipe groups 1 can be specifically arranged according to the width of the saline-alkali land, and two adjacent irrigation pipe groups 1 are connected by a connecting pipe 2. The setting of the connecting pipe 2 can connect multiple irrigation pipe groups 1 to ensure that the irrigation water flow can enter each irrigation pipe group 1.

[0029] In this embodiment, the irrigation pipe group 1 is configured as a whole to be in an arch shape, which can slow down the flow of water and reduce the occurrence of turbulence and turbulence. In order to facilitate installation, the irrigation pipe group 1 is terminated and connected by a plurality of arc-shaped water pipes 101. The arc-shaped water pipes 101 are bent upward, and the curvature of the water pipe 101 located in the middle is the largest, and the curvatures of the water pipes 101 on both sides decrease successively.

[0030] On the basis of the above structure, in order to improve the stability and connection strength of the plurality of irrigation pipe groups 1, Figure 2Two reinforcing rods 9 are connected to both sides of the two water pipes 101 at the head end and the tail end of each irrigation pipe group 1, and multiple tripods 10 are connected between the two reinforcing rods 9 and the multiple water pipes 101, and the reinforcing rods 9 are arranged in an arc shape, bending outward relative to the irrigation pipe group 1, so that the tripod 10 is convenient to install. By installing the tripod 10, on the one hand, the support for the irrigation pipe group 1 is improved, and on the other hand, the irrigation pipe group 1 and the two reinforcing rods 9 form a triangular structure and are connected, thereby improving the connection strength of the irrigation pipe group 1.

[0031] Furthermore, in order to irrigate different positions of the saline-alkali land simultaneously, the multiple irrigation pipe groups 1 are connected to multiple water outlet pipes 3, and the water outlet pipes 3 are connected to the water pipe 101. One water pipe 101 is connected to one or more water outlet pipes 3, and the water outlet end of the water outlet pipe 3 is vertically downward. Moreover, the upper end of the water outlet pipe 3 is connected to the irrigation pipe group 1 through the U-shaped pipe 11, and the opening of the U-shaped pipe 11 faces downward, so that when the water pipe 101 supplies water to the water outlet pipe 3, the water flow can first flow upward into the U-shaped pipe 11, which can further slow down the water flow rate, and avoid the water flow from the water outlet pipe 3 too fast or too much during irrigation, so that the water flow can be irrigated to the saline-alkali land more slowly, avoiding excessive impact on the ground surface.

[0032] On the basis of the above structure, the end of the irrigation pipe group 1 at the end is blocked, and the irrigation pipe group 1 at the head end is connected to the water source. Specifically, the first irrigation pipe group 1 is connected to the water inlet pipe 4, and the water inlet pipe 4 is arranged on the mounting frame 5, and is connected to the water source through the water hose 6. The mounting frame 5 mainly includes a base frame 51 and a conical frame 52. The base frame 51 can be set to a flat plate shape, and the conical frame 52 is composed of four inclined columns, the bottom end of which is installed on the base frame 51, and the water inlet pipe 4 is set to an L shape. The top ends of the four columns are all installed on the outer surface of the vertical section of the L-shaped water inlet pipe 4, and the horizontal section of the water inlet pipe 4 is installed on the base frame 51. In order to facilitate the control of the connection between the water inlet pipe 4 and the irrigation pipe group 1, a switch valve 14 is provided in the vertical section of the water inlet pipe 4.

[0033] In order to enable the device to be moved to a location far from the water source for irrigation, combined with Figure 3 The water hose 6 is set to be longer in length, and a component for storing the water hose 6 is set on one side of the mounting frame 5, wherein a tape reel 13 is rotatably installed on one side of the conical frame 52 through a bracket 12, and the water hose 6 is wound around the outer edge of the tape reel 13, one end of the water hose 6 is connected to the water inlet pipe 4, and the other end is connected to the water source. During irrigation, the water hose 6 can be pulled out from the tape reel 13 and connected to the water source, so that the irrigation system can be moved to a position far away from the water source for irrigation, and the moving length depends on the length of the water hose 6, which can be determined according to specific irrigation needs.

[0034] In the present embodiment, in order to facilitate movement and enable irrigation of different areas of the saline-alkali land, movable wheels 7 are correspondingly installed at the four corners on both sides of the mounting frame 5, that is, they are installed at the four corners of the base frame 51. Correspondingly, a support frame 8 is installed at the bottom of the connecting pipe 2, and a movable wheel 7 is also installed at the bottom of the support frame 8. Specifically, the support frame 8 is provided with two, and the two support frames 8 are both arranged in an inverted triangle shape, and the two support frames 8 are inclined from the connecting pipe 2 toward the direction away from the two, and are connected between the bottom ends by a connecting rod, and a movable wheel 7 is correspondingly installed between the bottom ends of the two, that is, two movable wheels 7 are provided under each connecting pipe 2, and are flush with the bottom of the movable wheel 7 installed on the base frame 51, supported on the ground, and in order to avoid the outlet pipe 3 from being too low to have a large impact on the ground, the bottom end of the outlet pipe 3 is 20cm-50cm higher than the lowest position of the movable wheel 7.

[0035] Specifically, when irrigating saline-alkali land, the irrigation system is placed in the saline-alkali land, the water hose 6 is removed from the belt wheel and connected to the water source, the switch valve 14 is opened, and the water flows through the water inlet pipe 4 and flows to the ground in multiple water outlet pipes 3, and can be moved along the saline-alkali land for irrigation in conjunction with the moving wheel 7.
