Separately controlled multiple outlet drip irrigation device

Abstract

This utility model discloses a separately controlled multi-channel drip irrigation device, the structure of which includes a water tank, a water pump on the side of the water tank, a water pipe connected to the water pump, a branch pipe on the water pipe, and several emitters evenly distributed on the branch pipe. A limit rod is also connected to the branch pipe, with its two ends connected to the water tank and the branch pipe respectively. An elastic sheet is provided to adapt and compensate for pressure. When the water pressure increases, the elastic sheet is compressed and indented, reducing the cross-sectional area of ​​the flow channel, thereby limiting the increase in flow rate. When the pressure decreases, the elastic sheet recovers its elasticity, increasing the flow channel area and compensating for the decrease in flow rate due to insufficient pressure. The inclusion of a guide pipe increases the length of the water flow path, and the width of the flow channel is shortened compared to a straight-flow channel, reducing the fluctuation range of water flow velocity and lowering the impurity deposition rate.

Description

Technical Field

[0001] This utility model is a multi-channel drip irrigation device with independent control, belonging to the field. Background Technology

[0002] Drip irrigation equipment is a general term for the combination of irrigation tools used in drip irrigation technology. It mainly includes components such as drippers, drip tape, and drip pipe. This equipment is widely used for irrigation of wide-row, high-value crops, as well as forestry and garden plants. Due to its significant advantages such as water saving, labor saving, fertilizer saving, and increased yield, drip irrigation technology has become an important representative of modern irrigation technology. Traditional drip irrigation equipment suffers from flow rate fluctuations due to pressure variations, leading to reduced irrigation uniformity and the accumulation of impurities over long-term use. To address these issues, a multi-output drip irrigation system with individually controlled flow is proposed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-channel drip irrigation device with independent control in order to solve the existing problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a separately controlled multi-channel drip irrigation device, the structure of which includes a water tank, a water pump provided on the side of the water tank, a water pipe connected to the water pump, a branch pipe on the water pipe, an emitter connected to the branch pipe, several emitters evenly distributed on the branch pipe, a limit rod connected to the branch pipe, the two ends of the limit rod being connected to the water tank and the branch pipe respectively. The water tank, water pump, etc. are all conventional structures, so they will not be described in detail.

[0005] Furthermore, the water dispenser consists of an inlet chamber and an outlet chamber, and an elastic sheet is provided between the inlet chamber and the outlet chamber. The elastic sheet is a silicone rubber diaphragm with a hardness of 70°.

[0006] Furthermore, the water outlet cavity is provided with a guide pipe, which is bent and located inside the water outlet cavity.

[0007] Furthermore, the inner wall of the flow channel of the guide tube is provided with serrated protrusions, and the serrated protrusions are provided at each bend in the guide tube.

[0008] Furthermore, the elastic sheet has a circular opening at the middle position and a trapezoidal opening on the elastic sheet. Several trapezoidal openings are provided and are distributed equidistantly in a ring on the elastic sheet. The bottom of the trapezoidal opening is connected to the circular opening.

[0009] The beneficial effects of this utility model are: By incorporating an elastic plate to adapt to and compensate for pressure, when the water pressure increases, the elastic plate is compressed and indented, reducing the cross-sectional area of ​​the flow channel and thus limiting the increase in flow rate. When the pressure decreases, the elastic plate recovers its elasticity, increasing the flow channel area and compensating for the decrease in flow rate caused by insufficient pressure. By incorporating a guide pipe, the length of the water flow path is increased, and the width of the flow channel is shortened compared to a straight flow channel, thereby reducing the range of water flow velocity fluctuations and lowering the impurity deposition rate. Serrated protrusions are installed at the bends of the guide pipe. When the water flows, it disrupts the laminar flow state and forms turbulence. Turbulence can enhance the water flow's ability to carry impurities and reduce sedimentation. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Please see Figures 1-4 This utility model provides a technical solution for a multi-channel drip irrigation device with independent control: its structure includes a water tank 1, a water pump 2 is provided on the side of the water tank 1, a water pipe 3 is connected to the water pump 2, a branch pipe is provided on the water pipe 3, an emitter 4 is connected to the branch pipe, several emitters 4 are provided and evenly distributed on the branch pipe, and a limit rod 5 is also connected to the branch pipe, with the two ends of the limit rod 5 connected to the water tank 1 and the branch pipe respectively; The watering device 4 consists of an inlet chamber 6 and an outlet chamber 7. An elastic sheet 8 is provided between the inlet chamber 6 and the outlet chamber 7. A circular opening 11 is provided in the middle of the elastic sheet 8, and a trapezoidal opening 12 is provided on the elastic sheet 8. Several trapezoidal openings 12 are provided and are distributed in a ring at equal intervals on the elastic sheet 8. The bottom of the trapezoidal opening 12 is connected to the circular opening 11. The water outlet cavity 7 is provided with a guide pipe 9. The guide pipe 9 is bent and located in the water outlet cavity 7. The inner wall of the bend of the guide pipe 9 is provided with serrated protrusions 10. The serrated protrusions 10 are located at each bend in the guide pipe 9.

[0014] For example, water pump 2 pumps water from water tank 1 to water dispenser 4 for watering; When the water dispenser 4 dispenses water, after the water flows through the inlet chamber 6, the elastic plate 8 adjusts itself according to the pressure and the water flows into the guide pipe 9. The water is then impacted and broken by the serrated protrusions 10 inside the guide pipe 9 and discharged.
