DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Embodiment: A pump-connected water supply detection irrigation system, such as Figure 1 As shown, it includes a water supply device, a soil moisture monitoring device 11, an electronic fence 9 for dividing the water supply area into regions, an irrigation network, a controller and a pipe network component.

[0020] Among them, the soil moisture monitoring device is installed in the soil to monitor the moisture content of the soil and is connected to the controller; the electronic fence divides the irrigation area into electronic areas, and an irrigation network is set up within the electronic fence and connected to the controller; the water supply device is connected to the irrigation network through the outlet pipe and supplies water to the soil under the control of the controller; the controller controls the operation of the water supply device and the irrigation network according to the monitoring information of the soil moisture monitoring device, and irrigates the soil in different electronic areas to different degrees.

[0021] The electronic fence includes a positioning device 10 and a satellite map. The positioning device locates the soil position, and the satellite map displays all the soil positions. Based on the positioning device, the soil is marked on the satellite map with colors of different depths. The depth of the color changes with the change of soil moisture. For example, different depths of red are used, from shallow to deep, to represent the degree of water shortage in the soil. The degree of water shortage in the soil is obtained through information monitored by the soil moisture monitoring device. As irrigation progresses, the degree of water shortage in the soil changes, and the color displayed on the electronic fence changes accordingly. The different contrasts of soil water shortage are directly represented by the change of color, which is more intuitive and efficient, so that the control personnel can better adjust the opening and closing of the pipe network components to control and adjust the irrigation system, thereby improving irrigation efficiency.

[0022] The water supply device includes a water supply pump and a water tank 1. The water supply pump is installed in the water supply tank. The control end of the water supply pump is connected to the controller. The water tank is connected to a water outlet pipe. The water outlet pipe is provided with a water supply valve. Under the control of the controller, the water supply pump draws water from the water tank and transports it to the water outlet pipe. The water outlet pipe is connected to the irrigation network.

[0023] The irrigation network includes a water supply network and a flow control network; the flow control network is connected to the outlet pipe 3, and the flow control network controls the flow rate of water transmitted by the outlet pipe under the control of the controller; the water supply network 2 is connected to the flow control network, and the water supply network adjusts the water supply angle and sprays water on the soil.

[0024] The flow control network includes a regulating box 4, a regulating pump installed in the regulating box, the regulating pump is connected to the controller, the water inlet of the regulating box is connected to the water supply device, the water outlet of the regulating box is provided with a regulating valve 5, the regulating valve is connected to the flow pipe 12, and the flow pipe is connected to the water supply network.

[0025] Furthermore, in order to better control the water flow, the flow control network is also provided with a water level sensor and a flow sensor. The water level sensor detects the water level information in the regulating box, and the flow sensor detects the water flow information in the flow pipe. Both the water level sensor and the flow sensor are connected to the controller.

[0026] The water supply network includes a spraying mesh 6, which is connected to a nozzle 8. The nozzle adjusts the water spraying angle and sprays water onto the soil. A spraying valve 7 is provided on the spraying mesh, and the control end of the spraying valve is connected to the controller.

[0027] like Figure 2As shown, the nozzle includes a shell and an adjusting part installed in the shell, the shell includes a fixed part 81 and a rotating part 82, the fixed part is connected to the spraying fine mesh, the rotating part is provided with a liquid outlet 85, the liquid outlet is provided with a spraying gap 86, the spraying gap is provided with an elastic magnetic sheet and a fixed magnetic sheet, the fixed magnetic sheet is on both sides of the spraying gap, the elastic magnetic sheet is fixedly connected to the bottom of the spraying gap, the elastic magnetic sheet and the fixed magnetic sheet are magnetically attracted to each other, and after the elastic magnetic sheet and the fixed magnetic sheet are attracted to each other, the elastic magnetic sheet covers the spraying gap.

[0028] The adjusting part includes an adjusting ball 83 and an adjusting spring 84, one end of the adjusting spring is connected to the adjusting ball, and the other end of the adjusting spring is connected to the inner wall of the fixed part. The adjusting ball is in contact with the liquid outlet, and a pressure sensor 87 is provided on the adjusting ball. When the water pressure impacts the adjusting ball so that the pressure detected by the pressure sensor exceeds the threshold, the rotating motor connected to the rotating part starts and drives the rotating part to rotate.

[0029] The working principle of the present invention is:

[0030] The irrigation system is divided into two modes: conventional irrigation and soil targeted irrigation. In the conventional irrigation mode, the controller obtains the irrigation area, sets the electronic fence, opens the spray valve in the area where the electronic fence is located, opens the regulating valve and water supply valve in the corresponding area of the spray mesh, controls the water supply pump to work, and stops the regulating pump. After the water flows through the outlet pipe to the regulating box, the water flow acts as a buffer to reduce the water flow rate. When it reaches the sprinkler through the flow pipe and the spray mesh, the water pressure acts on the regulating ball. The water pressure and the gravity of the regulating ball overcome the elastic force of the regulating spring to do work, so that the regulating ball contacts the liquid outlet. However, due to the elastic force limitation of the regulating spring, the regulating ball cannot seal the liquid outlet, and water drips from the side of the regulating ball, realizing drip irrigation water supply in the sprinkler area.

[0031] In targeted soil irrigation mode, the controller detects the electronic fence set up in the irrigation area, opens the spray valve in the area where the electronic fence is located, opens the regulating valve and water supply valve in the area corresponding to the fine spray mesh, and controls the water supply pump. At the same time, the regulating pump operates, pressurizing the water in the regulating tank, causing the pressure of the water reaching the sprinkler head to increase. This overcomes the elastic force of the regulating spring, causing the regulating ball to seal the liquid outlet. Under the action of the water pressure, the water pressure is greater than the magnetic attraction between the elastic and fixed magnets. The elastic magnet at the sprinkler notch is separated from the fixed magnet, and the elastic magnet is deflected outward, causing water to spray out from the sprinkler notch. At the same time, the regulating ball pressurizes the pressure sensor when sealing the liquid outlet. The pressure sensor detects the pressure and transmits the information to the controller. The controller obtains water flow information and determines whether the water reaches the water-deficient area after spraying based on the location of the soil water shortage and the sprinkler head position. If the water is too far or too close, the motor can drive the rotating part to rotate, causing the starting spray angle of the sprinkler head to change, thereby changing the water landing point, achieving the purpose of precise water supply and irrigation.

[0032] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solution described in the claims.
