Description

Technical Field

[0001] This utility model relates to the field of irrigation-related technology, specifically to an irrigation flow control device. Background Technology

[0002] In various fields such as agricultural irrigation, garden irrigation, and greenhouse cultivation, precise control of irrigation water volume is not only crucial for water conservation but also directly related to the uniformity of crop growth and the realization of precision agriculture. Precision irrigation can avoid water waste and ensure that each crop receives timely and adequate water, thereby improving the quality and efficiency of agricultural production. Therefore, an irrigation flow control device is needed to assist in controlling the irrigation flow.

[0003] The existing technology has the following shortcomings: The existing technology disclosed in CN216314485U discloses an irrigation device that is easy to control the flow rate, "including: a box, a fixing block and a fixing plate, a water pump is installed inside the box, a control board is installed inside the box on one side of the water pump, a time switch is installed inside the box on the top of the control board, a motor is installed inside the box on the other side of the time switch, a wireless transmission antenna is installed on the top of the fixing block, a nozzle is installed on the other side of the fixing block, support plates are installed on both sides of the bottom of the box, and a soil moisture sensor is installed on the bottom of the fixing plate";

[0004] The irrigation equipment described above uses a time-controlled switch to control the irrigation flow rate. While this method achieves automation, its control logic has a fundamental flaw: it assumes that the amount of water flowing through the system is constant within a fixed time period. However, in actual irrigation systems, factors such as fluctuations in water pressure, changes in pipe resistance, and filter blockage can cause significant changes in the actual flow rate per unit time. Therefore, even within the same time period, the actual amount of water passing through may vary greatly. This "time-for-flow" method cannot adapt to dynamically changing operating conditions, makes it difficult to guarantee the accuracy of irrigation volume, and can lead to uneven irrigation or water waste.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, an irrigation flow control device includes a first water supply pipe 1. A valve seat 2 is installed at one end of the first water supply pipe 1 via a flange for water flow. A control component is provided on one side of the valve seat 2, which can control the irrigation flow. A filter screen is provided inside the first water supply pipe 1 for intercepting impurities.

[0023] like Figure 3As shown, the control assembly includes a first protective shell 3, which is integrally mounted on the top of the valve seat 2 to protect the worm gear 4, the first micro motor 6, the worm 7, and other structures. A worm gear 4 is rotatably mounted on the top of the first protective shell 3 to drive the valve disc 5 to rotate. The valve disc 5 is mounted on the bottom of the worm gear 4 via a vertical rod to open and close the seal between the first water supply pipe 1 and the second water supply pipe 9. A first micro motor 6 is bolted to the inner wall of the first protective shell 3 to drive the worm 7 to rotate, which in turn drives the valve disc 5 to rotate under the transmission of the worm gear 4. The output end of the first micro motor 6 is equipped with... The worm gear 7 drives the worm wheel 4 to rotate. A control box 8 is bolted to the side wall of the first protective shell 3 to control the first micro motor 6, the second micro motor 19, etc. The surface of the first protective shell 3 has heat dissipation holes. The worm wheel 4 meshes with the worm gear 7 for transmission. A rubber sealing ring is installed on the outside of the valve disc 5. The valve disc 5 is correspondingly set with the valve seat 2. In the initial state, the valve disc 5 is in a sealed state. During irrigation, the first micro motor 6 drives the valve disc 5 to rotate and open. After completing the quantitative irrigation, the first micro motor 6 drives the valve disc 5 to rotate and reset, which helps to complete the control of irrigation flow.

[0024] like Figure 2 As shown, a second water supply pipe 9 is installed at one end of the valve seat 2 via a flange for water flow. Two sets of guide plates 10 are symmetrically installed inside the second water supply pipe 9 to guide the water flow and ensure the rotation of the turbine 14. A clamp 11 is fitted on the outside of the second water supply pipe 9 to install and fix the reduction gearbox 12. The reduction gearbox 12 is installed on the top of the clamp 11 to reduce the rotation of the turbine 14 and prevent the output shaft 15 from rotating too fast. The second water supply pipe 9 and the reduction gearbox 12 are connected. An input shaft 13 is rotatably installed inside the speed reduction gearbox 12. A turbine 14 is sleeved on the outside of the input shaft 13 for recording the total water flow in the second water supply pipe 9. The water guide plate 10 is inclined. The input shaft 13 is located between the water guide plates 10. The turbine 14 is located inside the second water supply pipe 9. The water flow drives the turbine 14 to rotate. After being reduced in speed by the speed reduction gearbox 12, the rotation of the turbine 14 drives the output shaft 15 to rotate. The total water flow through the turbine 14 can be recorded to ensure quantitative irrigation.

[0025] like Figure 4As shown, an output shaft 15 is rotatably mounted inside the reduction gearbox 12 to drive the pointer 16 to rotate. The pointer 16 is mounted on the side wall of the output shaft 15. A flow meter 17 is mounted on the top of the reduction gearbox 12 for displaying and judging the water flow rate. A second protective shell 18 is bolted to the side wall of the reduction gearbox 12. A second micro motor 19 is bolted inside the second protective shell 18 to drive the transmission rod 20 to rotate, thereby adjusting the distance between the contact switch 21 and the pointer 16. The output end of the second micro motor 19 is mounted with the transmission rod 20. A contact switch 21 is installed at the bottom of the side wall of the rod 20. The flow disk 17 is sleeved and installed outside the output shaft 15. The surface of the flow disk 17 is provided with scale lines. The second micro motor 19 is concentrically arranged with the output shaft 15. The transmission rod 20 has an L-shaped structure. The contact switch 21 is connected to the first micro motor 6. The second micro motor 19 drives the transmission rod 20 to rotate, which can adjust the distance between the contact switch 21 and the pointer 16, thereby adjusting the total amount of irrigation. As irrigation proceeds, the pointer 16 rotates accordingly. When it touches the contact switch 21, irrigation stops, realizing quantitative irrigation.

[0026] The working principle of this utility model is as follows:

[0027] In the initial state, pointer 16 is in contact with contact switch 21. Before irrigation, the second micro motor 19 is controlled according to the required irrigation flow rate. The second micro motor 19 drives the transmission rod 20 to rotate at a certain angle. The user can determine the distance between the transmission rod 20 and pointer 16 according to the scale lines on the flow meter 17, thereby setting the irrigation flow rate. Then, the first micro motor 6 is started. The first micro motor 6 drives the worm gear 7 to rotate. The rotation of the worm gear 7 drives the worm wheel 4 to rotate. The rotation of the worm wheel 4 drives the valve disc 5 to rotate, which can release the seal and ensure the flow of water. The water flow causes the turbine 14 to rotate. The rotation of the turbine 14 drives the input shaft 13 to rotate. After the reduction gearbox 12, the rotation of the input shaft 13 drives the output shaft 15 to rotate slowly. The rotation of the output shaft 15 drives the pointer 16 to rotate. After the pointer 16 touches the contact switch 21, the valve disc 5 closes and irrigation stops, completing the quantitative irrigation and realizing the control of the irrigation flow rate, ensuring the accuracy of the irrigation amount, and avoiding uneven irrigation or water waste.
