For example, the flow rate adjustment of some drip irrigation devices is not flexible enough, making it difficult to meet the water requirements of different crops at different growth stages. The installation and maintenance of some drip irrigation systems are relatively complex, increasing the cost of use. In addition, some drip irrigation devices do not perform well in terms of irrigation uniformity, which can easily lead to insufficient or excessive irrigation in some areas. Therefore, we have launched a variable frequency water-saving drip irrigation device and control device. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A variable frequency water-saving drip irrigation device and control device includes a base plate 1, a water storage tank 2 fixedly connected to the upper end of the base plate 1, a tank cover 3 provided at the upper end of the water storage tank 2, a transparent cover 4 fixedly connected to the front of the outer surface of the water storage tank 2, a drain pipe 5 fixedly connected to the rear of the outer surface of the water storage tank 2, and a conveying device 6 fixedly connected to the right side of the outer surface of the water storage tank 2. Four irrigation devices 7 are inserted into the front and rear sides of the conveying device 6.

[0026] One end of the drain pipe 5 penetrates the rear wall of the water storage tank 2 and extends to the lower part of the interior of the water storage tank 2, and the other end of the drain pipe 5 is equipped with a drain valve. A sealing structure is provided between the tank cover 3 and the water storage tank 2.

[0027] In this embodiment, the irrigation device 7 includes a connecting tube 71, one end of which is fixedly connected to an irrigation pipe 72. A collar 73 is fitted around the rear of the outer surface of the irrigation pipe 72, and a soil-breaking cone rod 74 is fixedly connected to the lower end of the collar 73. A solenoid valve 75 is provided in the middle of the outer surface of the irrigation pipe 72. An irrigation head 76 is fixedly connected to the front of the outer surface of the irrigation pipe 72. Several water outlet holes 77 are opened on the outer surface of the irrigation head 76. An adjusting rod 710 is movably connected to the front end of the irrigation pipe 72. A round block 78 is fixedly connected to the front end of the adjusting rod 710. A piston cylinder 79 is fixedly connected to the rear end of the adjusting rod 710. The outer surface of the piston cylinder 79 is in close contact with the inner wall of the irrigation pipe 72. The water outlet holes 77 are distributed in a three-three ring at equal intervals on the outer surface of the irrigation head 76. The connecting tube 71 is inserted into the pipe hole 66 of the conveying device 6. The surface of the round block 78 is provided with anti-slip texture.

[0028] The above solution achieves on-demand irrigation through an adjustable structural design, effectively avoiding water waste and achieving water conservation. The design of the soil-breaking cone rod 74 and the collar 73 facilitates the installation and fixation of the device. The annular equidistant distribution of the water outlet 77 makes irrigation more uniform and improves the irrigation effect. The flexible water flow adjustment function meets the irrigation needs of different crops and different growth stages, improving irrigation efficiency and quality. Considering the need to meet the requirements of precise water flow control and adapt to the low flow rate of the drip irrigation system, the solenoid valve 75 is an M-3SEW6 type solenoid directional valve. This model of solenoid valve has a fast response speed, good sealing performance, and can accurately control the water flow interruption. It is suitable for precise control of water flow in the drip irrigation system, which helps to realize the water-saving and frequency conversion control functions of this patent.

[0029] In this embodiment, the conveying device 6 includes a three-way pipe 61. An intelligent irrigation valve 62 is provided on the upper part of the outer surface of the three-way pipe 61. The front part of the right end and the rear part of the right end of the three-way pipe 61 are respectively fixedly connected to a first conveying pipe 63 and a second conveying pipe 64. The front part of the outer surface of the first conveying pipe 63 and the rear part of the outer surface of the second conveying pipe 64 are both provided with four pipe holes 66. The left part of the outer surface of the first conveying pipe 63 and the left part of the outer surface of the second conveying pipe 64 are both provided with a micro water pump 65. The left end of the three-way pipe 61 is fixedly connected to the right part of the outer surface of the water storage tank 2. The intelligent irrigation valve 62 is installed in the middle position of the upper part of the outer surface of the three-way pipe 61. The four pipe holes 66 are linearly distributed at equal intervals on the first conveying pipe 63 and the second conveying pipe 64. The inlet of the micro water pump 65 is connected to the inside of the first conveying pipe 63 or the second conveying pipe 64.

[0030] Through the above scheme: the conveying device 6 is connected to the water storage tank 2 through the three-way pipe 61, and the intelligent irrigation valve 62 regulates the water flow switch and flow rate in real time. When the system is started, the micro water pump 65 draws water from the water storage tank 2. The water flow is divided into the first conveying pipe 63 and the second conveying pipe 64 through the three-way pipe 61, and finally evenly irrigates the crops through the pipe holes 66. Through the equally spaced pipe holes 66 and the double conveying pipe design, the water flow is evenly distributed, avoiding local over-flooding or drought. Each conveying pipe is equipped with 4 pipe holes 66, and the number of irrigation devices 7 can be flexibly increased or decreased according to the irrigation area. Multiple irrigation devices 7 can be used in parallel. The intelligent irrigation valve 62 adopts the RainBirdESP-LXIV model, which supports remote control and flow monitoring, and is adapted to the needs of precision agriculture.

[0031] It should be noted that this utility model is a variable frequency water-saving drip irrigation device and control device. First, before use, open the tank cover 3 and inject water into the water storage tank 2. The sealing structure between the tank cover 3 and the water storage tank 2 can effectively prevent water leakage. The transparent cover 4 on the front of the water storage tank 2 can be used to observe the internal water level. When it is necessary to clean the water storage tank 2, open the drain valve at one end of the drain pipe 5. Since one end of the drain pipe 5 passes through the rear wall of the water storage tank 2 and extends to the lower part of the interior, the sewage can be discharged. During operation, start the miniature water pump 65 in the conveying device 6. The inlet of the miniature water pump 65 is connected to the inside of the first conveying pipe 63 or the second conveying pipe 64. It draws the water in the water storage tank 2 into the first conveying pipe 63 and the second conveying pipe 64 through the three-way pipe 61. The intelligent irrigation valve 62 is installed in the middle of the upper part of the outer surface of the three-way pipe 61, which can intelligently control the overall water flow. After the water enters the first conveying pipe 63 and the second conveying pipe 64, the four pipe holes 66 in the first conveying pipe 63 and the second conveying pipe 64... The water is arranged linearly at equal intervals on the 4th surface. The connecting tube 71 is inserted into the pipe hole 66 of the conveying device 6, allowing water to flow into the irrigation pipe 72 of the irrigation device 7. The lower end of the collar 73 fitted onto the rear of the outer surface of the irrigation pipe 72 is fixedly connected to the soil-breaking cone rod 74, facilitating the insertion of the irrigation device 7 into the soil. The flow of water in the irrigation pipe 72 can be controlled by the solenoid valve 75. After the water reaches the irrigation head 76, the water will drip slowly from these outlet holes 77 because the outlet holes 77 are arranged in a three-three ring at equal intervals on the outer surface of the irrigation head 76. The drip irrigation system can be implemented. If it is necessary to adjust the water volume and frequency of drip irrigation, the circular block 78 can be pulled. The anti-slip texture on the surface of the circular block 78 makes it easy to operate. The circular block 78 drives the adjusting rod 710 to move, which in turn causes the piston cylinder 79 to move back and forth inside the irrigation pipe 72. Because the outer surface of the piston cylinder 79 is in close contact with the inner wall of the irrigation pipe 72, changing the position of the piston cylinder 79 can adjust the size of the water flow channel inside the irrigation pipe 72, thereby achieving the control of the drip irrigation frequency and water output, and achieving the purpose of water-saving irrigation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
