Description

Technical Field

[0001] The present invention belongs to the technical field of irrigation devices, and particularly relates to an automatic irrigation device for vegetation on high-steep slopes. Background Technique

[0002] Slope vegetation refers to the plant communities growing on the slope surface, including herbaceous plants, shrubs, vine plants, etc. Its main functions are to stabilize the slope, protect the slope surface, improve the environment and beautify the landscape.

[0003] When the existing slope vegetation is planted, in order to ensure the survival rate of the slope vegetation, manual watering of the slope vegetation is generally required, and the existing watering devices are mainly some criss-crossing water pipes. When using the water pipes to water the slope vegetation, since the area of the slope vegetation is generally large, the number of branch water pipes for watering is generally also large. Therefore, when the water flows from the main water pipe into the branch water pipes, the water pressure of the branch water pipes farther away from the water inlet end of the main water pipe is smaller, resulting in a smaller water flow sprayed from the farther branch water pipes. Furthermore, within the specified watering time, the farther branch water pipes cannot meet the watering requirements of the slope vegetation. In this case, it is necessary to appropriately extend the watering time, and the extension of the watering time also causes a waste of more water resources.

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

[0005] In view of the above problems, the present invention provides an automatic irrigation device for vegetation on high-steep slopes to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solutions: An automatic irrigation device for vegetation on high-steep slopes, including a main water pipe. A plurality of connecting pipes are connected to one side of the main water pipe. A branch water pipe is inserted at the end of the connecting pipe. A water flow regulating device is arranged in the branch water pipe. The water flow regulating device includes a limiting ring, a fixed pipe, a regulating plate, a conical plug, a sleeve, a rotating shaft and an impeller. The limiting ring is fixedly connected to the inner wall of the branch water pipe. The fixed pipe is slidably inserted into one end of the branch water pipe close to the main water pipe, and the end of the fixed pipe away from the main water pipe is in close contact with the limiting ring. The regulating plate is fixedly connected to the position of the fixed pipe close to the main water pipe, and a plurality of regulating holes with gradually changing apertures are annularly distributed on the regulating plate. The sleeve is fixedly inserted through the center of the regulating plate. The rotating shaft is rotatably inserted through the sleeve. The conical plug is fixedly sleeved on the rotating shaft. The diameter of the conical plug gradually decreases in the direction close to the main water pipe, and the larger diameter end of the conical plug is close to the regulating plate. A plurality of through holes are penetrated through the conical plug, and both the conical plug and the regulating plate have magnetism. The impeller is fixedly installed at one end of the rotating shaft close to the main water pipe, and the impeller is located inside the main water pipe.

[0007] Further, an annular collecting groove is arranged on the side wall of the branch water pipe close to one end of the main water pipe. A filtering component is arranged inside the collecting groove. The filtering component includes a conical filtering cover, an annular filtering plate and a tension spring. The filtering cover is slidably sleeved on the sleeve, and the diameter of the filtering cover gradually decreases in the direction close to the main water pipe. The annular filtering plate is inserted at the opening end of the filtering cover, and the end of the annular filtering plate away from the filtering cover is fixedly connected to the inner wall of the collecting groove on the side away from the main water pipe. The tension spring is sleeved on the end of the sleeve away from the main water pipe, and both ends of the tension spring are fixedly connected to the inner side of the smaller end of the filtering cover and the end of the sleeve away from the main water pipe respectively. The bottom end of the collecting groove is connected with a sewage discharge pipe, and the bottom end of the sewage discharge pipe is threadedly sleeved with a sealing cover.

[0008] Further, a shielding component is arranged inside the annular filtering plate. The shielding component includes an annular baffle, a first fixing rod, a pull rod, a circular plate, a return spring, a fixing ring and a second fixing rod. The annular baffle is slidably inserted into the inside of the annular filtering plate. The pull rod is located at the center of the annular baffle. The number of the first fixing rods is multiple, and multiple first fixing rods are fixedly connected between the inner wall of the annular baffle and the pull rod. The circular plate is fixedly sleeved on the pull rod, and the circular plate is farther away from the main water pipe than the first fixing rod. The fixing ring is slidably sleeved on the end of the pull rod away from the filtering cover. The number of the second fixing rods is also multiple, and multiple second fixing rods are fixedly connected between the inner wall of the branch water pipe and the outer side of the fixing ring. The return spring is sleeved on the pull rod, and both ends of the return spring are fixedly connected to the circular plate and the fixing ring respectively.

[0009] Further, a cleaning component is arranged on the inner side of the filter cover. The cleaning component includes a cleaning rod, bristles, and a third fixing rod. The number of cleaning rods is multiple, and the multiple cleaning rods are annularly distributed on the inner side of the filter cover. The bristles are uniformly arranged on one side of the cleaning rod close to the inner wall of the filter cover. The third fixing rod is fixedly connected to the side of the cleaning rod away from the bristles, and one end of the third fixing rod away from the cleaning rod is fixedly connected to one end of the rotating shaft away from the impeller.

[0010] Further, a plurality of spray heads are uniformly installed on the top of the branch water pipe. A control valve is installed on the branch water pipe, and the control valve is closer to the main water pipe than the spray heads.

[0011] Further, the number of the adjustment holes matches the number of the through holes. The diameters of the plurality of adjustment holes gradually decrease in the same direction, and the distance between two adjacent adjustment holes is smaller than the aperture of the through hole.

[0012] Further, magnetic blocks with the same number as the adjustment holes are annularly distributed on the side of the conical plug and the adjustment plate facing each other. The magnetic blocks on the conical plug and the magnetic blocks on the adjustment plate have opposite magnetic poles. And in the initial state, when the magnetic poles on the conical plug and the adjustment plate are aligned one by one to generate suction force, the through hole on the conical plug just remains aligned with the maximum diameter of the adjustment hole on the adjustment plate.

[0013] Further, a sealing ring is fixedly sleeved at one end of the branch water pipe close to the main water pipe, and one end of the connecting pipe away from the main water pipe is inserted into the sealing ring.

[0014] Further, the width of the annular baffle is matched with the width of the area where the filter holes of the annular filter plate are located. And in the initial state, the annular baffle is aligned with the area where the filter holes on the annular filter plate are located.

[0015] The technical effects and advantages of the present invention: 1. By providing a conical plug and an adjustment plate, when watering the slope plants, the branch water pipes at different distances can adaptively adjust the water inflow of the corresponding branch water pipes by changing the rotation angle of the corresponding conical plug, so that the multiple branch water pipes can relatively evenly share the water pressure, ensure the irrigation amount of each branch water pipe to the slope vegetation, shorten the irrigation time, and save water resources; 2. The present invention is provided with a filter cover. When water flows through the through hole on the conical block and the adjustment hole on the adjustment plate into the area where the filter cover is located during irrigation operation, the filter cover can filter impurities in the water, and the impurities filtered by the filter cover can enter the collection tank along the conical surface of the filter cover, thereby avoiding excessive impurities from adhering to the filter cover and ensuring the filtering effect of the filter cover. Subsequently, the impurities entering the collection tank can be retained in the collection tank under the filtering effect of the annular filter plate. Since the collection tank is not directly opposite to the inside of the branch water pipe, the impurities in the collection tank will not block the flow of water, thereby ensuring the water flow speed of the branch water pipe; 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 smoothly enter the collection tank along the surface of the filter cover under the drive of the water flow and be collected. When the annular baffle blocks the filter hole area of ​​the annular filter plate again, the impurities originally attached to the annular filter plate can move downward along the annular filter plate under the action of gravity and finally be deposited in the sewage pipe, thereby avoiding the annular filter plate being blocked by impurities; 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 can be used to clean the filter cover, thereby preventing impurities from adhering to the filter cover and ensuring the filtering effect of the filter cover.

Specific implementation mode

[0018] To make the objectives, 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.

[0019] The present invention provides an automatic irrigation device for vegetation on high and steep slopes as Figures 1 to 6 shown, which includes a main water pipe 1. A plurality of connecting pipes 2 are connected to one side of the main water pipe 1. The end of the connecting pipe 2 is inserted with a branch water pipe 3. A water flow regulating device is arranged in the branch water pipe 3. The water flow regulating device includes a limiting ring 4, a fixed pipe 5, an adjusting plate 6, a conical plug 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 inserted into one 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 in contact with the limiting ring 4. The adjusting plate 6 is fixedly connected to the position of the fixed pipe 5 close to the main water pipe 1, and a plurality of adjusting holes 11 with gradually changing apertures are annularly distributed on the adjusting plate 6. The sleeve 8 is fixedly inserted through the center of the adjusting plate 6. The rotating shaft 9 is rotatably inserted through the sleeve 8. The conical plug 7 is fixedly sleeved on the rotating shaft 9. The diameter of the conical plug 7 gradually decreases towards the direction close to the main water pipe 1, and the end with the larger diameter of the conical plug 7 is close to the adjusting plate 6. A plurality of through holes 12 are formed through the conical plug 7, and both the conical plug 7 and the adjusting plate 6 have magnetism. The impeller 10 is fixedly installed at one 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; A number of spray heads 29 are evenly installed at 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 spray heads 29. The number of the adjustment holes 11 matches that of the through holes 12. The diameters of the multiple adjustment holes 11 gradually decrease in the same direction, and the distance between two adjacent adjustment holes 11 is smaller than the aperture of the through hole 12. Magnets with the same number as the adjustment holes 11 are annularly distributed on one side of the conical plug 7 and the adjustment plate 6 facing each other. The magnets on the conical plug 7 and the magnets on the adjustment plate 6 have opposite magnetic poles. In the initial state, when the multiple magnetic poles on the conical plug 7 and the adjustment plate 6 face each other one by one and generate suction force, the through hole 12 on the conical plug 7 just faces the maximum diameter of the adjustment hole 11 on the adjustment plate 6; By providing the conical block 7 and the regulating plate 6, when water is poured, as the water flows into the main water pipe 1, when the water flows into the impeller 10 to drive 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 gradually staggers with a certain regulating hole 11 on the regulating plate 6, 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 is gradually increased, the water flow entering the branch water pipe 3 through the regulating hole 11 is gradually increased. 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 impeller 10 at the ends of different branch water pipes 3, the thrust force exerted on the impeller 10 at the ends of each branch water pipe 3 is The impeller 10 is 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 When the magnetic blocks on the main water pipe 1 are aligned and adsorbed together again, due to the existence of suction, the conical block 7 can accelerate its rotation, 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 easier to keep aligned with the maximum diameter of the adjustment hole 11 on the adjustment plate 6, so that more water can flow into the branch water pipe 3 far away from the water inlet end of the main water pipe 1, so as to meet the irrigation needs of the slope vegetation at a farther distance and shorten the irrigation time; When the flow rate at the branch water pipe 3 far 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, so that the conical plug 7 at the branch water pipe 3 can rotate, thereby reducing the water inflow of the branch water pipe 3. Through the above adjustment method, the branch water pipes 3 at different distances can adaptively adjust the water inflow of the corresponding branch water pipes 3 by changing the rotation angle of the corresponding conical plug 7, so that the multiple branch water pipes 3 can relatively evenly share the water pressure, ensure the irrigation amount of each branch water pipe 3 for the slope vegetation, shorten the irrigation time, and save water resources.

[0020] As Figures 1 to 6 shown, an annular collecting groove 13 is arranged on the side wall of the branch water pipe 3 close to one end of the main water pipe 1. A filtering component is arranged inside the collecting groove 13. The filtering component includes a conical filtering cover 14, an annular filtering plate 15 and a tension spring 16. The filtering cover 14 is slidably sleeved on the sleeve 8, and the diameter of the filtering cover 14 gradually decreases in the direction close to the main water pipe 1. The annular filtering plate 15 is inserted into the open end of the filtering cover 14, and one end of the annular filtering plate 15 away from the filtering cover 14 is fixedly connected to the inner wall of the collecting groove 13 away from one side of the main water pipe 1. The tension spring 16 is sleeved on the end of the sleeve 8 away from the main water pipe 1, and both ends of the tension spring 16 are respectively fixedly connected to the inner side of the smaller end of the filtering cover 14 and the end of the sleeve 8 away from the main water pipe 1. The bottom end of the collecting groove 13 is connected with a sewage pipe 17, and the bottom end of the sewage pipe 17 is threadedly sleeved with a sealing cover 18; When connecting the branch water pipe 3 with the connecting pipe 2, as the branch water pipe 3 is inserted into the connecting pipe 2, the filtering cover 14 can also contact the annular filtering plate 15. At this time, as the branch water pipe 3 continues to be inserted, the filtering cover 14 can move in the direction close to the main water pipe 1 under the pushing of the annular filtering plate 15. During this process, the tension spring 16 is gradually stretched, and the filtering cover 14 can be stably pressed together with the annular filtering plate 15 under the reaction force of the tension spring 16, thereby ensuring the firmness and sealing performance of the plug connection between the two; When performing irrigation operations, as water flows into the branch water pipe 3, when the water passes through the through hole 12 on the conical plug 7 and the adjustment hole 11 on the adjustment 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 is conical, the impurities filtered by the filter cover 14 can enter the collection tank 13 along the conical surface of the filter cover 14, thus preventing excessive impurities from adhering to the filter cover 14 and ensuring the filtering effect of the filter cover 14. Subsequently, the impurities that enter 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 inside of the branch water pipe 3, when the water passes through the filter cover 14, the impurities in the collection tank 13 will not block the flow of the water, thereby ensuring the water flow rate in the branch water pipe 3; 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 the water intake of the main water pipe 1. At this time, the impurities deposited in the collection tank 13 can be discharged from the sewage pipe 17, thereby preventing the collection tank 13 from being blocked by impurities.

[0021] As Figure 3 and Figure 6 shown, a shielding assembly is provided inside the annular filter plate 15. 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 inside the annular filter plate 15. The pull rod 21 is located at the axis of the annular baffle 19. The number of the first fixing rods 20 is multiple, and the 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 farther from the main water pipe 1 than the first fixing rod 20. 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 both ends of the return spring 23 are fixedly connected to the circular plate 22 and the fixing ring 24 respectively. 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 is directly opposite to the area where the filter holes on the annular filter plate 15 are located; By providing a shielding component, during the irrigation process, as the overlapping area of ​​the adjusting hole 11 on the adjusting plate 6 and the through hole 12 on the conical blocking 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. In 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 flow from the outer side of the annular filter plate 15 to the inner side thereof through the unblocked part of the annular filter plate 15. In this process, the impurities filtered by the filter cover 14 can be driven by the water flow and smoothly flow along the surface of the filter cover 14. The impurities enter the collecting groove 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 blocking block 7 gradually decreases, the thrust of the water flow on the circular plate 22 is also reduced. At this time, with the resetting of the reset spring 23, 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 finally be deposited in the sewage pipe 17, thereby preventing the annular filter plate 15 from being blocked by impurities.

[0022] 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. The number of the cleaning rods 26 is multiple, 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, and the third fixed rod 28 is fixedly connected to the side of the cleaning rod 26 away from the bristles 27, and one end of the third fixed rod 28 away from the cleaning rod 26 is fixedly connected to one end of the rotating shaft 9 away from the impeller 10; 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 filter cover 14 is cleaned by the bristles 27 on the cleaning rod 26, thereby avoiding the adhesion of impurities on the filter cover 14 and ensuring the filtering effect of the filter cover 14.

[0023] like Figure 3 As shown, the branch water pipe 3 is fixedly sleeved at one end close to the main water pipe 1 with a sealing ring 31, and the end of the connecting pipe 2 away from the main water pipe 1 is inserted into the sealing ring 31; By providing a sealing ring 31, after connecting the branch water pipe 3 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.
