Description

Technical Field

[0001] This utility model relates to the field of intelligent water pressure balancing technology for irrigation, specifically an intelligent water pressure balancing device for group irrigation. Background Technology

[0002] In modern agriculture and landscape gardening, stable and appropriate water pressure is crucial for the healthy growth of plants and the maintenance of the landscape effect. Various physiological activities of plant cells, such as photosynthesis, respiration, and cell elongation and expansion, all require a suitable water environment. Stable water pressure can ensure that plant roots absorb water evenly and fully to meet their growth needs. For landscape gardening, stable water pressure can make the sprinkler system spray water evenly, maintaining the consistency and aesthetics of the landscape.

[0003] In traditional group irrigation systems, sprinkler branch pipes typically lack effective filtration measures. Impurities in the water source, such as silt, algae, microorganisms, and other debris, are carried directly into the sprinkler branch pipes by the water flow. These impurities gradually accumulate in branch pipe components, such as electric regulating valves, water pressure sensors, and sprinkler heads, leading to blockages. Frequent blockages significantly shorten the lifespan of these branch pipe components, increasing maintenance costs and replacement frequency. To ensure the normal operation of the irrigation system, staff need to spend a lot of time and effort on cleaning and maintenance, which undoubtedly reduces work efficiency and hinders the efficient implementation of group irrigation. To address this, we propose an intelligent water pressure balancing device for group irrigation. Utility Model Content

During sprinkler irrigation, water is diverted from the main pipe 1 to each branch pipe sprinkler device, and the branch pipe sprinkler devices can balance the pressure of the irrigation water to ensure uniform coverage of the water sprayed from each branch pipe sprinkler device.

[0023] Furthermore, the main pipe 1 has multiple sets of side pipes 6 arranged symmetrically on its side wall, and the side pipes 6 are connected to the inside of the main pipe 1. The side pipes 6 are connected to the branch pipe spraying device, and the side pipes 6 play a connecting role.

The pressure stabilizing tank 2 is provided with a filter cylinder 9 on the side away from the mating pipe 8. The filter cylinder 9 has a mating cavity 10 inside, and the filter assembly 7 is placed inside the mating cavity 10. The shaft end of the filter cylinder 9 is provided with a flange that is connected to the electric regulating valve 3 by an adapter bolt. When the water pressure is too high, the pressure stabilizing tank 2 can store some water to reduce the water pressure. When the water pressure is too low, the pressure stabilizing tank 2 releases the stored water to replenish the water pressure, thereby stabilizing the water pressure. The mating cavity 10 ensures that the filter assembly 7 can filter efficiently.

[0025] Furthermore, the filter assembly 7 has a cylindrical structure and consists of two parts: a filter frame 11 and a set of equally spaced filter plates 12. The filter frame 11 is fitted with the filter plates 12. The filter assembly 7 achieves efficient filtration of the irrigation water through multiple filter plates 12, preventing the irrigation water from clogging the electric regulating valve 3, water pressure sensor 4, and rotating nozzle 5. This can significantly improve the quality of irrigation and the service life of the overall device.

[0026] Furthermore, the filter frame 11 has a set of equally spaced connection ports 13 on its side wall. The connection ports 13 are semi-circular. The filter frame 11 also has a set of equally spaced mating grooves 14 inside, which correspond to the connection ports 13. The filter frame 11 also has easy-to-remove openings 15 on both sides of the connection ports 13 on its outer side. The easy-to-remove openings 15 are equally spaced. The unique structure of the semi-circular connection ports 13 of the filter frame 11 facilitates the quick replacement and cleaning of the filter plate 12, thereby improving the overall replacement rate.

[0027] Furthermore, the filter plate 12 is connected to the mating groove 14, and a filter screen 16 is provided inside the filter plate 12. Both opposite axial ends of the filter plate 12 are provided with a ring of protrusions 17 arranged in an annular array. The protrusions 17 are engaged with the inner wall of the mating groove 14.

The sizes of the various filter screens 16 inside the filter plate 12 are different, which effectively improves the filtration quality.

[0047] Working Principle: The intelligent water pressure balancing device for group irrigation is installed correctly according to the diagram. When using the device, water first flows into the main pipe 1. Multiple sets of side pipes 6, symmetrically distributed along the side wall of the main pipe 1, introduce water into the spray devices of each branch pipe. The water flow first passes through the pressure stabilizing tank 2. The fitting pipe 8 on the bottom side wall of the pressure stabilizing tank 2 is connected to the shaft end of the side pipe 6. When the water pressure is too high, the pressure stabilizing tank 2 functions to store some water and reduce the water pressure. When the water pressure is too low, it releases the stored water to replenish the water pressure, ensuring that subsequent equipment can operate under stable water pressure. Next, the water flows into the filter assembly 7, which is placed in the fitting cavity 10 of the filter cylinder 9. The filter cylinder 9 is connected to the electric regulating valve 3 via a flange. The filter assembly 7 consists of a filter frame 11 and multiple sets of filter plates 12. The filter plates 12 have filter screens 16 of different sizes inside, and the filter plates 12 are engaged with the fitting grooves 14 inside the filter frame 11 via protrusions 17, achieving… Multi-stage filtration of the water flow effectively blocks impurities such as silt, algae, and microorganisms, preventing them from entering the subsequent electric regulating valve 3, water pressure sensor 4, and rotary sprinkler head 5, thus avoiding blockages. The filtered water continues to flow to the electric regulating valve 3, which, based on data monitored by the water pressure sensor 4 and under the control of the intelligent control unit, precisely adjusts the valve opening to further fine-tune the water pressure. The water pressure sensor 4 monitors the water pressure in real time and feeds the data back to the control unit, forming a closed-loop control to ensure that the output water pressure remains stable within a suitable range. Finally, the water, after pressure stabilization, filtration, and regulation, is sprayed out from the rotary sprinkler head 5, achieving uniform sprinkler irrigation. Throughout the process, the main pipe 1, pressure stabilizing tank 2, filter assembly 7, electric regulating valve 3, water pressure sensor 4, and rotary sprinkler head 5 work together to not only ensure stable water pressure but also extend the service life of each component through filtration, thereby improving the quality and efficiency of sprinkler irrigation.
