These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] Generally, when there is a small flow leakage in the irrigation pipe network, the pressure in the pipe will drop significantly. In order to ensure normal irrigation, the pressure of the irrigation pipe network itself needs to be maintained by the pressure water. This will cause the water pump to start frequently, which not only consumes electricity but also easily causes damage to the water pump and causes unstable pressure. In addition, the current irrigation system is limited by the device itself. In addition to irrigation with clean water, the solution needs to be prepared in advance. This operation is time-consuming and labor-intensive, affecting irrigation efficiency.

[0022] In response to the above problems, the solution provided in the present application can store water and liquid fertilizer by equipping a water tank and a fertilizer storage tank, and transport them through the first suction pump and the second suction pump to the mixing tank for preparation through the agitator, without the need for manual processing, thereby speeding up the irrigation efficiency. By connecting the first suction pump, the second suction pump, and the booster pump with a frequency converter, and installing a pressure-stabilizing tank in the connecting pipe, when the system needs to be adjusted during irrigation work, the pressure-stabilizing state of the equipment can be maintained under the working condition of frequency conversion processing.

[0023] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 , the present application provides a constant pressure variable frequency irrigation system device, including a water tank 1, a fertilizer storage tank 2, a first suction pump 4, a second suction pump 6, a pressure stabilizing tank 9, a mixing tank 10, a frequency converter 12, a controller 13, a booster pump 14, and an irrigation pipe 15;

[0025] In the present embodiment, the water tank 1 is connected to the first suction pump 4 through the pipe 3, and the first suction pump 4 is connected to the connecting pipe 7 through the pipe 3; specifically, the first suction pump 4 is connected to the quartz sand filter 8 for filtering the water source through the pipe 3, and the quartz sand filter 8 is connected to the connecting pipe 7 through the pipe 3. In the present embodiment, the water tank 1 can be set up in the open air and can store water to a certain extent on rainy days. However, since the open-air structure is used to store rainwater, some small particles of debris will inevitably exist in the stored water. Therefore, after the first suction pump 4 draws water from the source, the water source is filtered through the quartz sand filter 8 to prevent subsequent pipelines 3 or equipment from being blocked during long-term use.

[0026] The fertilizer storage tank 2 is connected to the second suction pump 6 through the pipeline 3, and the second suction pump 6 is connected to the connecting pipe 7 through the pipeline 3. The water source inside the water tank 1 is collected in the connecting pipe 7, and the fertilizer storage tank 2 also transports the liquid fertilizer to the connecting pipe 7 through the second suction pump 6, so that the water source and the liquid fertilizer are preliminarily mixed.

[0027] In this embodiment, the connecting pipe 7 is connected to the liquid inlet of the pressure-stabilizing tank 9, and the liquid outlet of the pressure-stabilizing tank 9 is connected to the mixing tank 10 through the pipeline 3. The agitator 11 is installed inside the mixing tank 10 for stirring the water source and liquid fertilizer mixed along the connecting pipe 7. The mixing tank 10 is connected to the booster pump 14 through the pipeline 3, and the booster pump 14 is connected to the irrigation pipe 15 through the pipeline 3. The nozzles 16 are evenly distributed on the irrigation pipe 15. Specifically, the pressure-stabilizing tank 9 is connected to the controller 13, and the stable pressure in the pipeline 3 system is maintained by controlling the pressure in the tank to prevent the material in the pipeline 3 system from being damaged or leaking due to excessively high or low pressure. The solenoid valve 17 is installed on the pipeline 3 for connecting the mixing tank 10 and the booster pump 14, which is used to control the prepared solution to enter the booster pump 14. In this embodiment, the irrigation pipe 15 can also be equipped with several groups of irrigation pipes 15 plus booster pumps for use according to the actual use site.

[0028] In this embodiment, the first suction pump 4, the second suction pump 6, and the booster pump 14 are all connected to a frequency converter 12, and the frequency converter 12 is connected to a controller 13, and the controller 13 is a PLC.

[0029] Specifically, a flow meter 5 is installed on the pipe 3 at the liquid outlet of the first suction pump 4 and the second suction pump 6. The flow meter 5 is also connected to the PLC and can achieve the effect of controlling the ratio of the solution by calculating the flow rate. The staff only needs to operate on the PLC without having to mix the solution by themselves.

[0030] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
