[0008] The mixing pipeline sequentially includes an input section, a liquid mixing section, and an output section. The cross-sectional flow area of the liquid mixing section is smaller than that of the input section and the output section, and the liquid mixing output end is located in the liquid mixing section;

[0009] The integrated irrigation device further includes a gas mixing pipeline;

[0010] The gas mixing pipeline has a gas mixing input end for connecting a mixed gas supply pipeline; the gas mixing pipeline also has a gas mixing output end, and the gas mixing output end is connected to the mixing pipeline;

[0011] A venturi-shaped aeration member is arranged inside the mixing pipeline. The outer wall of the aeration member is hermetically sealed with the inner wall of the mixing pipeline to form an annular gas cavity for gas circulation, and the gas mixing output end is communicated with the annular gas cavity;

[0012] The aeration member is provided with a plurality of nano-pores, and the gas in the gas mixing pipeline enters the gas mixing section through the nano-pores;

[0013] The gas mixing pipeline is communicated with the aeration member through two gas mixing output ends.

[0014] In one embodiment, the integrated irrigation device further includes a gas mixing pipeline;

[0015] The mixing pipeline further includes a gas mixing section, the gas mixing section is located between the input section and the output section, and the cross-sectional flow area of the gas mixing section is smaller than the cross-sectional flow areas of the input section and the output section.

[0016] In one embodiment, there are two gas mixing output ends, and they are symmetrically arranged on both sides of the aeration member.

[0023] Due to the adoption of the above technical solutions, the present invention has the following advantages:

[0024] When using this irrigation device, irrigation water continuously flows into the mixing pipeline through the main input end. At the same time, the fertilizer solution to be mixed continuously flows into the mixing pipeline through the mixing liquid pipeline, realizing the mixing of the fertilizer solution and water. During the mixing process, the water first enters the input section, and then enters the mixing liquid section to be mixed with the fertilizer solution. Since the cross-sectional flow area of the mixing liquid section is smaller than that of the input section and the output section, when the water flows from the input section into the mixing liquid section, the cross-sectional flow area decreases, so the flow rate of the water increases when it flows through the mixing liquid section. When the water reaches the output section, the cross-sectional flow area increases and the flow rate of the water decreases, forming a Venturi effect. Therefore, when the water flows through the mixing liquid section, a low-pressure area is formed at the mixing liquid section. On the one hand, it generates a negative pressure on the mixing liquid pipeline for transporting the fertilizer solution, reducing the working pressure and power of the fertilizer injection pump body. At the same time, the change in the flow rate can also increase the turbulence effect of the water, enabling the fertilizer solution and water to be fully mixed, realizing the mixing of the fertilizer solution and irrigation water, and improving the irrigation efficiency of farmland.

[0034] For crops, simple irrigation cannot increase their yields. Fertilizer needs to be mixed into the irrigation water. Generally, people apply fertilizer manually by spraying it on the farmland. This requires manual irrigation work and additional manual fertilization work, resulting in a relatively low overall work efficiency. In view of the existing technical problems, the present invention provides an integrated irrigation device and an irrigation system that can integrate the mixing of fertilizer solution and irrigation water and improve the irrigation efficiency of farmland.

[0035] The technical solution of the present invention will be described in detail below with specific examples.

[0036] Refer to Figure 1 and Figure 2 As shown, an integrated irrigation device according to the present invention includes a mixing pipeline 10 and a liquid mixing pipeline 20. Among them, one end of the mixing pipeline 10 is a main input end 101, and the main input end 101 is used to connect to a water supply pipeline. The other end of the mixing pipeline 10 is a main output end 102, and the main output end 102 is used to connect to an irrigation pipeline. One end of the liquid mixing pipeline 20 is a liquid mixing input end 201, and the liquid mixing input end 201 is used to connect to a mixed liquid supply pipeline. The other end of the liquid mixing pipeline 20 is a liquid mixing output end 202, and the liquid mixing output end 202 is connected to the mixing pipeline 10. Among them, the mixing pipeline 10 sequentially includes an input section A, a liquid mixing section C, and an output section D. The cross-sectional flow area of the liquid mixing section C is smaller than the cross-sectional flow areas of the input section A and the output section D. The liquid mixing output end 202 is located in the liquid mixing section C.

[0037] It should be noted that in this embodiment, the irrigation water flows into the mixing pipeline 10 through the main input end 101, and the fertilizer solution to be mixed into the water body enters the liquid mixing pipeline 20 through the liquid mixing input end 201. The fertilizer solution enters the mixing pipeline 10 through the liquid mixing output end 202, thus realizing the mixing of the fertilizer solution and the water body.

[0038] Exemplarily, when using this irrigation device, irrigation water continuously flows into the mixing pipe 10 through the main input end 101. At the same time, the fertilizer solution to be mixed continuously flows into the mixing pipe 10 through the mixing liquid pipe 20, realizing the mixing of the fertilizer solution and water. During the mixing process, the water first enters the input section A, and then enters the mixing liquid section C to be mixed with the fertilizer solution. Since the cross-sectional flow area of the mixing liquid section C is smaller than that of the input section A and the output section D, when the water flows from the input section A into the mixing liquid section C, the cross-sectional flow area decreases, so the flow rate of the water increases when it flows through the mixing liquid section C. When the water reaches the output section D, the cross-sectional flow area increases and the flow rate of the water decreases, forming a Venturi effect. Therefore, when the water flows through the mixing liquid section C, a low-pressure area is formed at the mixing liquid section C. On the one hand, it generates a negative pressure on the mixing liquid pipe 20 for transporting the fertilizer solution, reducing the working pressure and power of the fertilizer injection pump body. At the same time, the change in the flow rate can also increase the turbulence effect of the water, enabling the fertilizer solution and water to be fully mixed, realizing the mixing of the fertilizer solution and irrigation water, and improving the irrigation efficiency of farmland.

[0039] In one embodiment, in order to further optimize the mixing diversification performance of the irrigation device, the irrigation device further includes a gas mixing pipe 30. The gas mixing pipe 30 has a gas mixing input end 301, and the gas mixing input end 301 is used to connect to the mixed gas supply pipe; the gas mixing pipe 30 also has a gas mixing output end 302, and the gas mixing output end 302 is connected to the mixing pipe 10.

[0040] The mixing pipe 10 further includes a gas mixing section B, and the gas mixing section B is located between the input section A and the output section D, and the cross-sectional flow area of the gas mixing section B is smaller than that of the input section A and the output section D.

[0041] It should be noted that the gas to be mixed into the water enters the gas mixing pipe 30 through the gas mixing input end 301, and the gas enters the mixing pipe 10 through the gas mixing output end 302, thus realizing the mixing of the fertilizer solution and water.

[0042] Exemplarily, when gas needs to be mixed into the water, irrigation water continuously flows into the mixing pipe 10 through the main input end 101. At the same time, the gas to be mixed continuously flows into the mixing pipe 10 through the gas mixing pipe 30, realizing the mixing of the gas and water. During the mixing process, the water first enters the input section A, and then enters the gas mixing section B to be mixed with the fertilizer gas.

[0043] In this embodiment, a Venturi-shaped aeration member 31 is arranged inside the mixing pipe 10. The outer wall of the aeration member 31 is sealed with the inner wall of the mixing pipe 10 to form an annular gas cavity 32 for gas circulation, and the gas mixing output end 302 is communicated with the annular gas cavity 32. At the same time, the aeration member 31 is provided with a plurality of nano pores 333, and the gas in the gas mixing pipe 30 enters the gas mixing section B through the nano pores 333.

[0044] It should be noted that for the venturi-shaped aeration member 31, both ends thereof have a relatively large cross-sectional flow area, while the cross-sectional flow area in the middle is relatively small.

[0045] Exemplarily, during the mixing process, the water body first enters the input section A, and then enters the air mixing section B to be mixed with the fertilizer gas. Since the cross-sectional flow area in the middle of the aeration member 31 is smaller than that at both ends, when the water body flows from the input section A into the middle of the aeration member 31, the cross-sectional flow area decreases, so the flow rate of the water body increases when it flows through the middle of the aeration member 31. When the water body reaches the end of the aeration member 31, the cross-sectional flow area increases and the flow rate of the water body decreases, forming a Venturi effect. Therefore, when the water body flows through the middle of the aeration member 31, a low-pressure area is formed in the middle of the aeration member 31. On the one hand, a negative pressure is generated on the air mixing pipeline 30 for transporting gas, reducing the working pressure and power of the air injection pump body. On the other hand, the gas in the aeration member 31 is easily overflowed and mixed with the water body in the mixing pipeline 10, enabling the irrigation device to simultaneously achieve the mixing of fertilizer solution, gas and irrigation water.

[0046] It should be noted that the Venturi effect formed by the aeration member 31 enables a low pressure to be generated in the middle of the aeration member 31. With the assistance of the low pressure, it is not necessary to connect a high-power air pump to work on the air mixing pipeline 30, and a small-power air pump can be selected. Since the volume of the small-power air pump is much smaller than that of the high-power air pump, the design volume of the overall system can be reduced, enabling the overall system to be miniaturized.

[0047] In this embodiment, preferably, there are two air mixing output ends 302, which are symmetrically arranged on both sides of the aeration member 31, and the air mixing pipeline 30 is connected to the aeration member 31 through the two air mixing output ends 302. The setting of multiple air mixing output ends 302 can further increase the air supply speed of the air mixing pipeline 30 and optimize the air mixing efficiency of the irrigation device.

[0048] In this embodiment, the aeration member 31 is further refined. There are two aeration members 31, which are arranged at both ends of the liquid mixing section C. The number and position of the air mixing output ends 302 are correspondingly set with the aeration member 31. Specifically, the two aeration members 31 are symmetrically arranged on both sides of the liquid mixing section C, and each of the two aeration members 31 is correspondingly provided with two air mixing output ends 302, and the air mixing output ends 302 are all connected to the air mixing pipeline 30. The setting of multiple aeration members 31 can further optimize the gas dissolution efficiency. It should be noted that in this embodiment, the air mixing output end 302 is arranged with a narrow middle and widened ends to facilitate the addition and uniform diffusion of gas.

[0049] Preferably, in this embodiment, an air adding member 33 is provided inside the mixing pipe 10. The air adding member 33 is located in the middle of the liquid mixing section C. The air adding member 33 is communicated with the air mixing pipe 30. A plurality of nano pores 333 are also provided on the air adding member 33. The air mixing pipe 30 is communicated with the mixing pipe 10 through the air adding member 33. Specifically, both ends of the air adding member 33 are tapered to form a flow guiding end 331. Specifically, the nano pores 333 have a pore axis, the pore axis is inclined, and the air outlet direction of the nano pores 333 is set in the same direction as the fluid flow direction of the mixing pipe 10. For details, please refer to Figure 2 as shown.

[0050] It should be noted that the setting of the air adding member 33 not only further optimizes the gas dissolution efficiency, but also the tapered settings at both ends can play a role in guiding the flow. The outer wall of the air adding member 33 and the inner wall of the liquid mixing section C form a cavity for the water body to flow through. The tapered settings at both ends make the cross-sectional flow areas at both ends of the liquid mixing section C larger, enabling a low-pressure area similar to that in the middle of the air mixing section B to be formed in the middle of the liquid mixing section C, realizing efficient mixing of the fertilizer solution.

[0051] Preferably, in this embodiment, air inlet pipes 332 are provided at both ends of the air adding member 33, and the air inlet pipes 332 are correspondingly inserted into the adjacent aeration members 31. Specifically, a plurality of nano pores 333 are also provided on the air inlet pipes 332. The air inlet pipes can also play an effect of optimizing the gas dissolution efficiency. In addition, the air inlet pipes inserted into the aeration members 31 can also play a role in guiding the flow of the water body.

[0052] This irrigation device is an integrated fertilizer-water-air machine, which can simultaneously mix the fertilizer solution, gas and irrigation water. At the same time, the main components in the irrigation device are all installed inside the mixing pipe 10. The overall structure of the device occupies a small area and can be directly installed on the irrigation pipe, which is convenient for installation.

[0053] In some extended embodiments, an integrated irrigation device further includes an air path check valve 34, and the air path check valve 34 is installed at the air mixing input end 301 of the air mixing pipe 30 to prevent reverse gas transmission. A fertilizer solution controller, a fertilizer injection pump, a flow meter 21 and a liquid check valve 22 are sequentially arranged between the liquid mixing input end 201 and the liquid mixing output end 202 of the liquid mixing pipe 20.

[0054] Among them, the fertilizer solution controller dynamically adjusts the driving motor speed of the fertilizer injection pump according to the output value of the flow meter 21 through an adaptive PID control algorithm to keep the concentration of the fertilizer solution loop stable. When the working conditions of the irrigation system change, the adaptive PID control algorithm dynamically adjusts the system PID parameters through dynamic learning to ensure that it is in the optimal working condition. The irrigation device is also provided with a touch screen.

[0055] In addition, a dissolved oxygen sensor and a pressure sensor are provided in the output section D of the mixing pipe 10. The dissolved oxygen sensor is used to measure the dissolved oxygen concentration in the water-fertilizer mixture, and the pressure sensor measures the water pressure at the end of the device, so that the irrigation device can make adaptive adjustments based on the data in the subsequent process.

[0056] The present invention also provides an irrigation system, including an integrated irrigation device mentioned in the above solution.

[0057] Among them, the irrigation water in the irrigation system continuously flows into the mixing pipe 10 through the main input end 101. At the same time, the fertilizer solution to be mixed continuously flows into the mixing pipe 10 through the mixing solution pipe 20 to achieve the mixing of the fertilizer solution and the water body. During the mixing process, the water body first enters the input section A, and then enters the mixing solution section C to be mixed with the fertilizer solution. Since the cross-sectional flow area of the mixing solution section C is smaller than that of the input section A and the output section D, when the water body flows from the input section A into the mixing solution section C, the cross-sectional flow area decreases, so the flow rate of the water body increases when it flows through the mixing solution section C. When the water body reaches the output section D, the cross-sectional flow area increases and the flow rate of the water body decreases, forming a Venturi effect. Therefore, when the water body flows through the mixing solution section C, a low-pressure area is formed at the mixing solution section C. On the one hand, it generates a negative pressure on the mixing solution pipe 20 for transporting the fertilizer solution, reducing the working pressure and power of the fertilizer injection pump body. At the same time, the change in the flow rate can also increase the turbulence effect of the water body, enabling the fertilizer solution and the water body to be fully mixed, realizing the mixing of the fertilizer solution and the irrigation water, and improving the irrigation efficiency of farmland.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
