Description

Technical Field

[0001] This utility model relates to the field of saline-alkali land irrigation technology, and more specifically to a layered seepage irrigation water-saving device for plateau saline-alkali land. Background Technology

[0002] Currently, conventional surface irrigation methods have significant drawbacks when cultivating crops in high-altitude saline-alkali areas. On the one hand, due to intense evaporation in high-altitude regions, water is easily lost rapidly in the shallow surface layer, making it difficult to penetrate into deeper soil layers. On the other hand, saline-alkali land is prone to salt backflow, causing root salt damage and affecting crop survival and yield. To improve irrigation efficiency and suppress salt backflow, some areas have attempted to use buried drip irrigation pipes. However, existing structures are generally single-level irrigation systems, unable to simultaneously address both shallow wetting and deep water supply, and are prone to clogging and uneven seepage in the complex environment of saline-alkali land. Furthermore, traditional drip irrigation systems mostly lack effective water-saving controls and pipe protection structures, resulting in high operation and maintenance costs and short lifespans, making them unsuitable for widespread use in high-altitude saline-alkali areas. Therefore, there is an urgent need to develop a novel drip irrigation water-saving device with layered water supply, filtration, and control functions to address the problems of single-level water supply, weak salt and alkali resistance, and lack of control methods in existing technologies. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a layered seepage irrigation water-saving device for high-altitude saline-alkali land, so as to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a layered seepage irrigation water-saving device for high-altitude saline-alkali land, comprising a device body, the device body including an installation head, an irrigation head fixedly installed at the top of the installation head, the installation head and the irrigation head being positioned above the ground, the device body further including a layered irrigation module, the layered irrigation module comprising:

[0005] A shallow irrigation pipe is fixedly installed on the top of an installation head, and its interior communicates with the irrigation head. The shallow irrigation pipe is placed in shallow soil.

[0006] Small perforation holes, which are evenly distributed on the outer surface of the shallow irrigation pipe, have a diameter of one centimeter.

[0007] A deep irrigation pipe, the bottom end of which is connected to that of a shallow irrigation pipe, is installed in deep soil.

[0008] Large-pore permeability holes, each with a diameter of two centimeters, are evenly distributed on the outer surface of the deep irrigation pipe. By incorporating a tiered irrigation module, the system achieves simultaneous water supply to both shallow and deep soil layers, thus solving the problems of low irrigation water utilization and easy salt backflow in high-altitude saline-alkali lands.

[0009] Furthermore, a permeation connecting pipe is fixedly installed at the bottom end of the shallow irrigation pipe, and the bottom end of the permeation connecting pipe is connected to the top end of the deep irrigation pipe. The interior of the permeation connecting pipe is uniformly filled with a permeable material, namely glass wool. By setting up the permeation connecting pipe and the internal glass wool permeable material, a stable guiding and slow-release water supply channel is provided between the upper and lower irrigation structures.

[0010] Furthermore, a valve pipe is fixedly installed at the bottom end of the permeation pipe. The valve pipe is Z-shaped, and its bottom end is fixedly connected to the top end of the deep irrigation pipe. A ball valve is fixedly installed on the valve pipe, and a valve handle is provided at the top of the ball valve. By setting up the Z-shaped valve pipe and the ball valve, the effect of manually controlling the flow of deep irrigation water is achieved.

[0011] Furthermore, a sand-proof hollow tube is fixedly installed at the top of the spherical valve. The sand-proof hollow tube is hollow inside, and its top extends above the ground. The valve handle is located inside the sand-proof hollow tube. By setting up a sand-proof hollow tube and installing the valve handle within it, the effect of convenient adjustment on the ground without being covered by mud and sand is achieved.

[0012] Furthermore, both the deep and shallow irrigation pipes are covered with an outer permeable mesh, which is made of polyester fiber. By installing this outer permeable mesh, the clogging of the irrigation pipe openings by soil particles is prevented, while allowing water to seep out smoothly.

[0013] Furthermore, four insertion pins are fixedly installed at the bottom of the deep irrigation pipe. The bottom of each insertion pin is spiked, and multiple limiting blocks, all cross-shaped, are fixedly installed on the outer surface of each insertion pin. Both the insertion pins and the limiting blocks are positioned deep within the soil. By incorporating these insertion pins and limiting blocks, the overall stability of the device in the soil is improved, and displacement of the irrigation structure is prevented.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention, by incorporating a tiered irrigation module, achieves the effect of simultaneously supplying water to both shallow and deep soil layers, thus solving the problems of low irrigation water utilization and easy salt return in high-altitude saline-alkali lands.

[0016] This invention achieves the effect of providing a stable guiding and slow-release water supply channel between the upper and lower irrigation structures by incorporating a permeable connecting pipe and internal glass wool permeable material. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0023] Reference Figure 1 and Figure 2 This utility model provides a stratified seepage irrigation water-saving device for high-altitude saline-alkali land, including a device body. The device body includes an installation head 100, and an irrigation head 110 is fixedly installed on the top of the installation head 100. The installation head 100 and the irrigation head 110 are arranged above the ground. The device body also includes a stratified irrigation module, which includes:

[0024] Shallow irrigation pipe 111 is fixedly installed at the top of the installation head 100, and its interior is connected to the irrigation head 110. The shallow irrigation pipe 111 is placed in the shallow soil.

[0025] Small perforation holes 112 are evenly distributed on the outer surface of shallow irrigation pipe 111, and their diameter is one centimeter.

[0026] The deep irrigation pipe 113 is connected to the bottom end of the shallow irrigation pipe 111 and is installed in the deep soil.

[0027] Large-pore permeation holes 114 are evenly distributed on the outer surface of the deep irrigation pipe 113, and their diameter is two centimeters.

[0028] A permeation connecting pipe 115 is fixedly installed at the bottom end of the shallow irrigation pipe 111. The bottom end of the permeation connecting pipe 115 is connected to the top end of the deep irrigation pipe 113. The interior of the permeation connecting pipe 115 is uniformly filled with permeation material 116, which is glass wool.

[0029] A valve pipe 117 is fixedly installed at the bottom end of the infiltration pipe 115. The valve pipe 117 is Z-shaped. The bottom end of the valve pipe 117 is fixedly connected to the top end of the deep irrigation pipe 113. A ball valve 118 is fixedly installed on the valve pipe 117. A valve handle 119 is provided at the top end of the ball valve 118.

[0030] Working principle: When the user injects water into the irrigation head 110, the water flow first enters the installation head 100 and flows down into the shallow irrigation pipe 111. After being divided in the shallow irrigation pipe 111, the water flow evenly permeates into the shallow soil area through the small permeation holes 112, achieving basic irrigation for the shallow root system of crops. When the shallow soil reaches saturation, or when deeper water needs to be supplied according to irrigation requirements, the water flow will continue to flow down through the connected permeation pipe 115 into the deep irrigation pipe 113. During this process, the permeable material 116, such as glass wool, filled inside the permeation pipe 115 can perform secondary slow release, filtration, and guidance of the water flow, which helps to stabilize and evenly infiltrate the water flow.

[0031] To control whether water flows into the deep irrigation pipe 113, the ball valve 118 installed on the valve pipe 117 can be adjusted. When the ball valve 118 is closed, deep irrigation is blocked, and water circulates only in the shallow layer. When the ball valve 118 is open, water flows smoothly into the deep irrigation pipe 113 and then seeps out through the large permeable holes 114 evenly distributed on its surface, achieving precise water supply to the deep soil. The valve handle 119 is installed inside the sand-proof hollow pipe 120 and extends above the ground surface, allowing users to operate it directly from outside the ground. This effectively prevents silt from burying or blocking the adjustment mechanism, thus ensuring long-term and reliable operation of the device in high-altitude or saline-alkali areas. Example 2

[0032] Reference Figure 1 The difference between Embodiment 2 and Embodiment 1 is that: a sand-proof hollow tube 120 is fixedly installed on the top of the ball valve 118, the sand-proof hollow tube 120 is hollow inside, the top of the sand-proof hollow tube 120 extends to the ground, and the valve handle 119 is set inside the sand-proof hollow tube 120.

[0033] Both the deep irrigation pipe 113 and the shallow irrigation pipe 111 are covered with an outer layer of infiltration mesh 121, which is made of polyester fiber mesh.

[0034] Four soil-penetrating pins 122 are fixedly installed at the bottom of the deep irrigation pipe 113. The bottom of each soil-penetrating pin 122 is spike-shaped. Multiple limiting blocks are fixedly installed on the outer surface of each soil-penetrating pin 122. The limiting blocks are cross-shaped. Both the soil-penetrating pins 122 and the limiting blocks are located deep inside the soil.

[0035] Working principle: By fixing and installing a sand-proof hollow tube 120 at the top of the ball valve 118 and setting the valve handle 119 inside it, the valve adjustment structure can be extended to the ground surface, avoiding the valve mechanism from being buried by mud and sand, improving the convenience and reliability of maintenance in plateau or saline-alkali soil environments, and ensuring that users can directly complete the opening and closing of irrigation levels on the ground.

[0036] Secondly, both the shallow irrigation pipe 111 and the deep irrigation pipe 113 are covered with an outer permeable mesh 121. This permeable mesh is made of polyester fiber material, which has good corrosion resistance and flexibility. It can effectively prevent soil particles from entering the permeable holes 112 and 114 and causing blockage, while ensuring that water can seep out smoothly, thereby improving the overall permeable irrigation efficiency and service life of the device.

[0037] Finally, four insertion pins 122 are installed at the bottom of the deep irrigation pipe 113. The pins have spiked ends for easy insertion into dense soil. Multiple cross-shaped limiting blocks are provided on the outer surface of the pins. Once inserted, these blocks create physical resistance deep within the soil, effectively preventing the entire device from loosening or shifting due to external forces or groundwater flow, thus enhancing the anchoring stability of the entire unit in complex soil environments. Through the synergy of these structures, this embodiment further improves the environmental adaptability and field practicality of the equipment.
