Description

Technical Field

[0001] This utility model relates to the field of drip irrigation flow control technology, specifically to a high-precision drip irrigation flow control device. Background Technology

[0002] Drip irrigation, as an emerging water-saving irrigation technology, has developed rapidly in my country in recent years. Drip irrigation pipes are the key equipment in drip irrigation systems. Installing drippers on the pipes allows pressurized water to be delivered evenly and stably into the soil after being de-energized, effectively improving water resource utilization. Because the irrigation water does not travel through the air and only wets a portion of the soil surface, it effectively reduces ineffective evaporation of soil moisture, maintaining optimal soil moisture levels for crops. Localized irrigation is achieved by creating multiple orifices along the length of the drip irrigation pipe or installing drippers to deliver water to the crop roots.

[0003] However, this method results in the same drainage volume for each orifice or dripper, while the soil moisture requirements of each crop are different. As a result, some orifices or drippers may lead to waste of tap water, and in more serious cases, excessive soil moisture may cause damage to crops. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that the existing method results in the same drainage volume for each orifice or dripper. However, the water requirements of the soil where each crop is located are different. Therefore, some orifices or drippers will lead to the waste of tap water.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a high-precision drip irrigation flow control device, comprising: a box body, an impeller, a rotating component, a sliding component, and a limiting plate; the impeller is rotatably mounted in the box body, and the impeller slides against the inner side wall of the box body; an inlet and an outlet are respectively opened on opposite sides of the box body to drive the impeller to rotate; the rotating component is perpendicular to the axis of the impeller, one end of the rotating component is hinged to the box body, and the impeller can drive the rotating component to rotate; the sliding component is slidably mounted on the rotating component along the length direction of the rotating component; a planar spiral groove is opened on the box body, and the planar spiral groove is coaxially arranged with the hinge point of the rotating component; the sliding component slides into the planar spiral groove; a slot is opened on the box body, and the extension line of the slot extends to the hinge point of the rotating component; one end of the limiting plate is slidably mounted in the slot.

[0006] Preferably, it further includes a first gear and a second gear; the first gear is fixedly connected to the rotating component, and the hinge point of the rotating component is located on the axis of the first gear; the second gear is coaxially fixed to the impeller, and the second gear meshes with the first gear.

[0007] Preferably, the number of teeth of the first gear is greater than the number of teeth of the second gear.

[0008] Preferably, it also includes a driving component, which can drive the limiting piece to slide.

[0009] Preferably, it also includes a partition plate, which is fixedly installed in the box body, the impeller is disposed on one side of the partition plate, and the rotating member, sliding member and limiting piece are located on the other side of the partition plate.

[0010] Preferably, the device also includes a spiral spring, which is coaxially mounted on the impeller, with one end of the spiral spring mounted on the impeller and the other end mounted on the housing.

[0011] Compared with the prior art, the present invention has at least the following advantages:

[0012] 1. In this utility model, water enters the drip irrigation pipe towards the inlet, flows into the housing, and flows towards the outlet, thereby driving the impeller to rotate. The impeller drives the rotating component to rotate, and the sliding component moves along the length of the rotating component and slides along the length of the planar spiral groove until the sliding component abuts against the limiting plate. In this way, the rotation of the rotating component is restricted, thereby restricting the rotation of the impeller, and the impeller can cut off the inlet and outlet. Thus, by adjusting the position of the limiting plate, the sliding distance of the sliding component can be adjusted, thereby adjusting the number of rotations of the impeller and realizing the regulation of the drip irrigation flow rate. In this way, high-precision drip irrigation can be performed on crops, reducing water waste.

[0013] 2. In this utility model, during drip irrigation, the water flow drives the impeller to rotate, and the impeller drives the volute spring to store energy; after drip irrigation is completed, the volute spring can drive the impeller to flip, which can drive the sliding part to slide in the reverse direction in the planar spiral groove, realize the reset of the sliding part, and facilitate the next drip irrigation.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] See Figures 1-4 The present invention provides an embodiment of a high-precision drip irrigation flow control device, comprising: a housing 1, an impeller 2, a rotating component 3, a sliding component 4, and a limiting plate 5; the impeller 2 is rotatably mounted inside the housing 1, and the impeller 2 slides against the inner side wall of the housing 1; an inlet 6 and an outlet 7 are respectively provided on opposite sides of the housing 1 to drive the impeller 2 to rotate; the rotating component 3 is perpendicular to the axis of the impeller 2, and one end of the rotating component 3 is hinged to the housing 1, allowing the impeller 2 to drive the rotating component 3 to rotate; the sliding component 4 is slidably mounted on the rotating component 3 along its length; a planar spiral groove 8 is provided on the housing 1, and the planar spiral groove 8 is coaxially arranged with the hinge point of the rotating component 3; the sliding component 4 extends slidably into the planar spiral groove 8; a slot 9 is provided on the housing 1, and the extension line of the slot 9 extends to the hinge point of the rotating component 3; one end of the limiting plate 5 is slidably mounted in the slot 9.

[0022] In practice, the inlet 6 is connected to the drip irrigation pipe, and water enters the pipe through the inlet 6. The water flows into the housing 1 and towards the outlet 7, which in turn drives the impeller 2 to rotate. The impeller 2 drives the rotating component 3 to rotate, and the sliding component 4 moves along the length of the rotating component 3 and slides along the length of the planar spiral groove 8 until it comes into contact with the limiting piece 5. This restricts the rotation of the rotating component 3, thereby restricting the rotation of the impeller 2, which in turn cuts off the connection between the inlet 6 and the outlet 7. By adjusting the position of the limiting piece 5, the sliding distance of the sliding component 4 can be adjusted, thereby adjusting the number of rotations of the impeller 2 and regulating the flow rate of the drip irrigation. This allows for high-precision drip irrigation of crops and reduces water waste.

[0023] See Figures 1-4In other embodiments, a first gear 10 and a second gear 11 are also included. The first gear 10 is fixedly connected to the rotating member 3, and the hinge point of the rotating member 3 is located on the axis of the first gear 10. The second gear 11 is coaxially fixed to the impeller 2, and the second gear 11 meshes with the first gear 10. In specific implementation, when the impeller 2 rotates, the impeller 2 drives the second gear 11 fixedly connected to it to rotate, and the second gear 11 drives the first gear 10 meshing with it to rotate. The first gear 10 can then drive the rotating member 3 fixed to it to rotate, thus realizing the rotation of the rotating member 3 through the impeller 2. Furthermore, the number of teeth of the first gear 10 is greater than the number of teeth of the second gear 11; so that when the impeller 2 drives the rotating member 3 to rotate, the first gear 10 and the second gear 11 achieve a deceleration effect, thereby reducing the number of turns of the planar spiral groove 8.

[0024] See Figures 1-4 In other embodiments, a driving element 12 is also included, which can drive the limiting plate 5 to slide. In specific implementation, the driving element 12 can be an electric push rod; by controlling the action of the driving element 12, the driving element 12 can drive the limiting plate 5 to slide, thereby adjusting the number of rotations of the impeller 2, thus eliminating the need for manual adjustment.

[0025] See Figures 1-4 In other embodiments, a partition 13 is also included. The partition 13 is fixedly installed inside the housing 1. The impeller 2 is located on one side of the partition 13, and the rotating part 3, the sliding part 4 and the limiting piece 5 are located on the other side of the partition 13. By setting the partition 13, the impeller 2 is located in an independent space, thereby reducing the generation of gaps and thus reducing water leakage, thereby improving the accuracy of crop drip irrigation flow.

[0026] See Figures 1-4 In another embodiment, a spiral spring is also included. The spiral spring is coaxially mounted on the impeller 2, with one end of the spiral spring installed on the impeller 2 and the other end installed on the housing 1. Specifically, during drip irrigation, the water flow drives the impeller 2 to rotate, and the impeller 2 drives the spiral spring to store energy. After drip irrigation is completed, the spiral spring drives the impeller 2 to rotate, thus causing the sliding member 4 to slide in the reverse direction within the planar spiral groove 8, achieving the reset of the sliding member 4 and facilitating the next drip irrigation.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
