Description

Technical Field

[0001] The invention belongs to the technical field of irrigation devices, and in particular relates to an automatic irrigation device for vegetation on high and steep slopes. Background Art

[0002] Slope vegetation refers to the plant communities growing on the slope surface, including herbs, shrubs, vines, etc. Its main function is to stabilize the slope edge, protect the slope surface, improve the environment and beautify the landscape.

[0003] When existing slope vegetation is planted, in order to ensure its survival rate, it is generally necessary to manually water the slope vegetation, and the existing irrigation devices are mainly a number of crisscrossing water pipes. When using water pipes to irrigate slope vegetation, since the area of ​​slope vegetation is generally large, there are generally more branch pipes used for irrigation. Therefore, when water flows through the main water pipe into the branch pipe, the water pressure of the branch pipe farther away from the water inlet end of the main water pipe is also lower, resulting in a smaller water flow ejected from the farther branch pipe. As a result, within the specified irrigation time, the farther branch pipe cannot meet the irrigation needs of the slope vegetation. In this case, it is necessary to appropriately extend the irrigation time, and the extension of the irrigation time also results in a large amount of water resources being wasted.

[0004] Therefore, it is necessary to invent an automatic irrigation device for high and steep slope vegetation to solve the above problems. Summary of the Invention

[0018] 2. The present invention is provided with a filter cover. When water flows through the through holes on the conical block and the regulating holes on the regulating plate into the area where the filter cover is located during irrigation, the filter cover can filter impurities in the water. Impurities filtered by the filter cover can enter the collection tank along the conical surface of the filter cover, thereby preventing excessive impurities from adhering to the filter cover and ensuring the filtering effect of the filter cover. Impurities that subsequently enter the collection tank can be retained in the collection tank under the filtering action of the annular filter plate. Since the collection tank is not directly opposite to the interior of the branch water pipe, the impurities in the collection tank will not block the flow of water, thereby ensuring the water flow rate of the branch water pipe.

[0019] 3. The present invention is provided with a shielding assembly. During the irrigation process, as the water flow hits the circular plate, the annular baffle can gradually stagger with the annular filter plate, so that the impurities filtered by the filter cover can be smoothly collected in the collection tank along the surface of the filter cover under the influence of the water flow. When the annular baffle again blocks the filter hole area of ​​the annular filter plate, the impurities originally attached to the annular filter plate can move downward along the annular filter plate under the action of gravity and eventually be deposited in the sewage pipe, thereby preventing the annular filter plate from being blocked by impurities.

[0020] 4. The present invention is provided with a cleaning assembly. During the rotation of the shaft, the shaft can drive the cleaning rod to brush along the inner wall of the filter cover through the third fixed rod, so that the bristles on the cleaning rod are used to clean the filter cover, thereby preventing impurities from adhering to the filter cover and ensuring the filtering effect of the filter cover.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides Figures 1 to 6 The automatic irrigation device for high and steep slope vegetation shown in the figure includes a main water pipe 1, one side of the main water pipe 1 is connected to a plurality of connecting pipes 2, the ends of the connecting pipes 2 are plugged with branch water pipes 3, and a water flow regulating device is provided in the branch water pipe 3, and the water flow regulating device includes a limiting ring 4, a fixed pipe 5, an adjusting plate 6, a conical block 7, a sleeve 8, a rotating shaft 9 and an impeller 10. The limiting ring 4 is fixedly connected to the inner wall of the branch water pipe 3, the fixed pipe 5 is slidably plugged into the end of the branch water pipe 3 close to the main water pipe 1, and the end of the fixed pipe 5 away from the main water pipe 1 is tightly attached to the limiting ring 4, and the adjusting plate 6 is fixedly connected to the fixed pipe 5 close to the main water pipe 1, and a plurality of adjusting holes 11 with gradually changing apertures are distributed in an annular manner on the adjusting plate 6, the sleeve 8 is fixedly inserted through the axis of the adjusting plate 6, and the sleeve 8 is rotated and inserted into the sleeve 8, the conical block 7 is fixedly sleeved on the rotating shaft 9, the diameter of the conical block 7 gradually decreases toward the direction close to the main water pipe 1, and the end of the conical block 7 with a larger diameter is close to the adjusting plate 6, a plurality of through holes 12 are opened on the conical block 7, and the conical block 7 and the adjusting plate 6 are both magnetic, and the impeller 10 is fixedly mounted on the end of the rotating shaft 9 close to the main water pipe 1, and the impeller 10 is located inside the main water pipe 1;

[0030] A plurality of sprinkler heads 29 are evenly installed on the top of the branch water pipe 3. A control valve 30 is installed on the branch water pipe 3, and the control valve 30 is closer to the main water pipe 1 than the sprinkler head 29. The number of the regulating holes 11 matches the number of the through holes 12. The diameters of the plurality of regulating holes 11 gradually decrease in the same direction, and the distance between two adjacent regulating holes 11 is smaller than the aperture of the through hole 12. The same number of magnetic blocks as the regulating holes 11 are distributed in an annular manner on the side facing the conical block 7 and the regulating plate 6. The magnetic poles of the magnetic blocks on the conical block 7 and the magnetic blocks on the regulating plate 6 are opposite. In the initial state, when the multiple magnetic poles on the conical block 7 and the regulating plate 6 are facing each other one by one and generate suction, the through hole 12 on the conical block 7 is just facing the maximum diameter of the regulating hole 11 on the regulating plate 6.

[0031] By providing the conical block 7 and the regulating plate 6, when watering, as the water flows into the main water pipe 1, when the water flow impacts the impeller 10 and drives the conical block 7 to rotate, the multiple through holes 12 on the conical block 7 can alternately correspond to the multiple regulating holes 11 on the regulating plate 6. In this process, when the through hole 12 of the conical block 7 and a certain regulating hole 11 on the regulating plate 6 are gradually staggered, since the diameter of the regulating hole 11 gradually decreases in the same direction, the water flow entering the branch water pipe 3 through the regulating hole 11 also gradually decreases, and as the through hole 12 on the conical block 7 moves toward the next regulating hole 11 on the regulating plate 6 When the diameter of the regulating hole 11 gradually increases, the water flow entering the branch water pipe 3 through the regulating hole 11 gradually increases. Therefore, during the rotation of the conical block 7, as the multiple through holes 12 on the conical block 7 continuously overlap or stagger with the multiple regulating holes 11 on the regulating plate 6, the water flow entering the branch water pipe 3 is also alternately reduced or increased. However, due to the difference in distance, the closer the branch water pipe 3 is to the water inlet end of the main water pipe 1, the higher the flow rate. Therefore, when water flows with different flow rates impact the impellers 10 at the ends of different branch water pipes 3, the thrust force exerted on the impeller 10 at the end of each branch water pipe 3 is greater. Also different, so that the impeller 10 closer to the water inlet end of the main water pipe 1 is easier to overcome the suction of the magnetic block and rotate under the action of the water flow, and the conical block 7 farther away from the water inlet end of the main water pipe 1 is more able to remain stationary or overcome the suction of part of the magnetic strips to deflect at a certain angle. In addition, during the rotation of the conical block 7, when the conical block 7 and the two magnetic blocks on the adjustment plate 6 are separated under the action of the water flow, the suction between the conical block 7 and the adjustment plate 6 is eliminated. Therefore, under the action of the water flow on the impeller 10, the conical block 7 can rotate more easily, and the magnetic blocks on the conical block 7 and the adjustment plate 6 are separated. When the magnetic blocks on the main water pipe 1 are aligned and adsorbed together again, the conical block 7 can accelerate its rotation due to the existence of suction, so that the through hole 12 on the conical block 7 can more quickly keep aligned with the maximum diameter of the adjustment hole 11 on the adjustment plate 6. Due to the existence of this situation and the relatively small water flow thrust on the impeller 10 on the branch water pipe 3 at a farther distance, the conical block 7 at the farther branch water pipe 3 is more likely to keep aligned with the maximum diameter of the adjustment hole 11 on the adjustment plate 6, thereby allowing more water to flow into the branch water pipe 3 away from the water inlet end of the main water pipe 1, meeting the irrigation needs of the vegetation on the slope at a farther distance and shortening the irrigation time;

[0032] When the flow velocity at the branch water pipe 3 away from the water inlet end of the main water pipe 1 increases, the thrust of the water flow on the impeller 10 at the end of the branch water pipe 3 farther away also gradually increases, thereby enabling the conical block 7 at the branch water pipe 3 to rotate, thereby reducing the water inlet volume of the branch water pipe 3. Through the above-mentioned adjustment method, the branch water pipes 3 at different distances can adaptively adjust the water inlet volume of the corresponding branch water pipe 3 by changing the rotation angle of the corresponding conical block 7, so that multiple branch water pipes 3 can share the water pressure relatively evenly, ensuring the irrigation volume of each branch water pipe 3 for the slope vegetation, shortening the irrigation time, and saving water resources.

[0033] like Figures 1 to 6 As shown, an annular collecting trough 13 is provided on the side wall of the branch water pipe 3 near one end of the main water pipe 1, and a filter assembly is provided inside the collecting trough 13, and the filter assembly includes a conical filter cover 14, an annular filter plate 15 and a tensioning spring 16, the filter cover 14 is slidably sleeved on the sleeve 8, and the diameter of the filter cover 14 gradually decreases towards the main water pipe 1, the annular filter plate 15 is inserted into the open end of the filter cover 14, and the end of the annular filter plate 15 away from the filter cover 14 is fixedly connected to the inner wall of the collecting trough 13 away from the main water pipe 1, the tensioning spring 16 is sleeved on the end of the sleeve 8 away from the main water pipe 1, and the two ends of the tensioning spring 16 are respectively fixedly connected to the inner side of the smaller end of the filter cover 14 and the end of the sleeve 8 away from the main water pipe 1, the bottom end of the collecting trough 13 is connected to a drain pipe 17, and the bottom end of the drain pipe 17 is threadedly sleeved with a sealing cover 18;

[0034] When connecting the branch water pipe 3 to the connecting pipe 2, as the branch water pipe 3 is inserted into the connecting pipe 2, the filter cover 14 can also contact the annular filter plate 15. At this time, as the branch water pipe 3 continues to be inserted, the filter cover 14 can be pushed towards the main water pipe 1 by the annular filter plate 15. During this process, the tension spring 16 is gradually stretched, and the filter cover 14 can be stably pressed together with the annular filter plate 15 under the reaction force of the tension spring 16, thereby ensuring the firmness and sealing of the insertion between the two.

[0035] During irrigation operation, as water flows into the branch pipe 3, when the water flows through the through hole 12 on the conical block 7 and the regulating hole 11 on the regulating plate 6 and enters the area where the filter cover 14 is located, the filter cover 14 can filter impurities in the water, and because the filter cover 14 has a conical surface, the impurities filtered by the filter cover 14 can enter the collection tank 13 along the conical surface of the filter cover 14, thereby avoiding excessive impurities from adhering to the filter cover 14 and ensuring the filtering effect of the filter cover 14. Subsequently, the impurities entering the collection tank 13 can be retained in the collection tank 13 under the filtering action of the annular filter plate 15. Since the collection tank 13 is not directly opposite to the interior of the branch pipe 3, when the water flows through the filter cover 14, the impurities in the collection tank 13 will not block the flow of water, thereby ensuring the water flow speed of the branch pipe 3.

[0036] After the filter cover 14 has been used for a period of time, the control valve 30 on the branch water pipe 3 can be closed, and the sealing cover 18 can be opened while ensuring water inflow to the main water pipe 1. At this time, the impurities accumulated in the collection tank 13 can be discharged from the sewage pipe 17, thereby preventing the collection tank 13 from being blocked by impurities.

[0037] like Figure 3 and Figure 6 As shown, a shielding assembly is provided on the inner side of the annular filter plate 15, and the shielding assembly includes an annular baffle 19, a first fixing rod 20, a pull rod 21, a circular plate 22, a return spring 23, a fixing ring 24 and a second fixing rod 25. The annular baffle 19 is slidably inserted into the inner side of the annular filter plate 15, and the pull rod 21 is located at the axis of the annular baffle 19. There are multiple first fixing rods 20, and multiple first fixing rods 20 are fixedly connected between the inner wall of the annular baffle 19 and the pull rod 21. The circular plate 22 is fixedly sleeved on the pull rod 21, and the circular plate 22 is larger than the first fixing rod 20. Further away from the main water pipe 1, the fixing ring 24 is slidably sleeved on the end of the pull rod 21 away from the filter cover 14, the number of the second fixing rods 25 is also multiple, and the multiple second fixing rods 25 are fixedly connected between the inner wall of the branch water pipe 3 and the outer side of the fixing ring 24, the return spring 23 is sleeved on the pull rod 21, and the two ends of the return spring 23 are respectively fixedly connected to the circular plate 22 and the fixing ring 24, the width of the annular baffle 19 matches the width of the area where the filter holes of the annular filter plate 15 are located, and in the initial state, the annular baffle 19 and the area where the filter holes on the annular filter plate 15 are located remain directly opposite;

[0038] By providing a blocking component, during the watering process, as the overlapping area of ​​the adjusting hole 11 on the adjusting plate 6 and the through hole 12 on the conical block 7 gradually increases, the force of the water flow filtered by the filter cover 14 on the circular plate 22 also gradually increases. At this time, the circular plate 22 can drive the pull rod 21 and the annular baffle 19 to move away from the filter cover 14 under the push of the water flow. During this process, the return spring 23 is compressed, and as the annular baffle 19 moves, the annular filter plate 15 gradually staggers with the annular filter plate 15. At this time, part of the water flow can pass through the unblocked part of the annular filter plate 15 and flow from the outside of the annular filter plate 15 to its inside. During this process, the impurities filtered by the filter cover 14 can be smoothly moved along the surface of the filter cover 14 driven by the water flow. The impurities enter the collecting tank 13 and are collected, thereby preventing excessive impurities from adhering to the surface of the filter cover 14. When the overlapping area of ​​the adjusting hole 11 on the adjusting plate 6 and the through hole 12 on the conical block 7 gradually decreases, the thrust of the water flow on the circular plate 22 also decreases. At this time, as the reset spring 23 is reset, the annular baffle 19 can re-block the filter hole area of ​​the annular filter plate 15 under the thrust of the reset spring 23. At this time, since the water flow no longer passes through the annular filter plate 15, the impurities originally attached to the annular filter plate 15 are no longer attached to the annular filter plate 15 due to the pressure of the water flow. Subsequently, the impurities can move downward along the annular filter plate 15 under the action of gravity and can eventually be deposited in the sewage pipe 17, thereby preventing the annular filter plate 15 from being blocked by impurities.

[0039] like Figure 3 and Figure 5 As shown, a cleaning assembly is provided on the inner side of the filter cover 14, and the cleaning assembly includes a cleaning rod 26, bristles 27 and a third fixed rod 28. There are multiple cleaning rods 26, and the multiple cleaning rods 26 are annularly distributed on the inner side of the filter cover 14. The bristles 27 are evenly arranged on the side of the cleaning rod 26 close to the inner wall of the filter cover 14. The third fixed rod 28 is fixedly connected to the side of the cleaning rod 26 away from the bristles 27, and the end of the third fixed rod 28 away from the cleaning rod 26 is fixedly connected to the end of the rotating shaft 9 away from the impeller 10.

[0040] By providing a cleaning assembly, during the rotation of the rotating shaft 9, the rotating shaft 9 can drive the cleaning rod 26 to brush along the inner wall of the filter cover 14 through the third fixed rod 28, so that the bristles 27 on the cleaning rod 26 are used to clean the filter cover 14, thereby preventing impurities from adhering to the filter cover 14 and ensuring the filtering effect of the filter cover 14.

[0041] like Figure 3 As shown, the branch water pipe 3 is fixedly sleeved with a sealing ring 31 at one end close to the main water pipe 1, and the end of the connecting pipe 2 away from the main water pipe 1 is inserted into the sealing ring 31;

[0042] By providing a sealing ring 31, after the branch water pipe 3 is connected to the main water pipe 1 through the connecting pipe 2, the sealing ring 31 can seal the connection between the branch water pipe 3 and the connecting pipe 2, thereby improving the sealing performance of the connection between the branch water pipe 3 and the connecting pipe 2, reducing the probability of water leakage at the connection between the branch water pipe 3 and the connecting pipe 2, and saving water resources.
