Description

Technical Field

[0001] The present invention relates to a method for controlling irrigation water flow for environmental protection and landscaping, a high-performance anti-fouling swing sprinkler and a water-saving method, an electromagnetic flowmeter and a circuit with an energy-saving new impeller suspension shaftless bracket for energy-saving agriculture and forestry irrigation, and a water-saving method, including a flow-adjustable dripper, a 360-degree nozzle, a joint with fine-tunable threaded ring size and pitch, and a combination with an energy-saving sprinkler timer and a water distributor with a multi-purpose interface, and a swing sprinkler with adjustable spraying angle, especially an ultrasonically controlled swing sprinkler with adjustable area. Background Art

[0002] The desire to pursue environmental protection and gardening is endless; there are also many patents on the control method of irrigation water flow and the patent of the garden sprinkler timer switch with long axis and two sides control, such as patent US7252113B2 and patent ZL200820120164.8, both of which use the garden sprinkler timer switch with long axis and two sides control. Although the mechanical timer has a wide range of uses due to its strong structure, strong weather resistance, reliable use, and excellent cost performance, the two ends of the double gear shaft (11) are respectively mounted in the two oblong holes of the mechanical timer frame, and only one end has an auxiliary spring, while the other end does not have an auxiliary spring, lacking the proper balancing torque, so when twisting and running, the double gear shaft (11) and the meshing main gear shaft (15) cannot be parallel, and there is a potential hidden danger of long-term operation wear resistance and stability. Furthermore, due to structural problems, the main control valve and the pilot valve are arranged on one side of the main channel, and the mechanical timer is arranged on the other side of the main channel, causing the mechanical timer to be far away from the main control valve and the pilot valve that it should directly control, and has to be remotely pushed out with a very long stainless steel rod, which not only creates higher requirements for the precision of manufacturing tolerance matching, but also causes the possibility of occasional Euler instability of the pressure rod during long-term use; it also causes the stainless steel rod to be exposed and pass through the main channel, which is prone to rust and adhesion over time and hinders the movement; in addition, the stainless steel rod passing through the main channel also has a problem of sealing and leakage over time. Furthermore, the scheme of arranging the main control valve and the pilot valve on one side of the main channel and arranging the mechanical timer on the other side of the main channel is based on the conventional idea that the remote main control valve, the pilot valve and the main channel are immovable relative to the main body of the mechanical timer. Therefore, the remote main control valve, the pilot valve and the main channel are connected to the main body of the mechanical timer by a larger housing, resulting in a larger appearance of the garden sprinkler timing switch; at the same time, in addition to the thin shaft of the main gear shaft (15) that plays a controlling role of the mechanical timer, a large rotating gradient circle and several parts have to be used for rotation and control, that is, the multiple parts make some aspects of the rotating gradient circle, such as the plastic square hole in the middle, subject to lateral deflection torque, causing the gradient circle disk surface to be skewed and affecting the effect.In summary, this type of watch product can be further improved. Considering the thousands of patents in eight countries that the inventor has obtained and the inspiration from others and some devices manufactured by foreign factories such as Switzerland and Israel, they can be improved and specially blended, and then supplemented with innovation to make the product better. However, even if the timer and sprinkler are easy to use, it will not work if the interface is not good. In practice, some are pipe interfaces, and some are faucets without threads. The method of adding multiple interfaces has been used, which is okay for faucets and some interfaces, but not for many interfaces. The reason is that many interfaces in a garden have been worn or rusted, and the threads of many interfaces have been loose, and they cannot be connected or connected. Tight, but leaking after connection, many interfaces have similar threads mixed with different threads; it is not easy to replace a large number of interfaces; even if they are replaced, many threads on the original water pipes also have loose teeth, and the replaced interfaces will also be worn or rusted, and the new interfaces also have many problems such as upper tolerance or lower tolerance and over-tolerance, and cannot be connected or cannot be connected tightly and have loose teeth; there is also the problem that it is slow to operate a thread by turning a small half circle with a hand tool and then turning a small half circle with a hand tool for many turns; whether it is used for sprinkler timers and irrigation water distributors or other, it is hoped that there will be a connector that can fine-tune the size and pitch of the thread ring so that it is widely applicable and can be connected quickly. There are many patents for water-saving sprinkler irrigation and drip irrigation, such as CN103651053A and 012055360, etc., each with its own advantages. Existing products are numerous and imperfect; there is a certain type of sprinkler, water is sprayed out through the only small square through hole set on the sprinkler cap as a water spray port, and its disadvantage is that the range of the sprayed water is narrow. Another type of existing product sprays water through a large through hole on the half side of the nozzle cap. The disadvantage is that the water sprayed only covers half of the nozzle, and there is no 360-degree irrigation effect. The regulation of drip irrigation water output, the regulation of irrigation water according to plant growth requirements, and the efficient water-saving irrigation that saves water resources are long-standing problems in the industry at home and abroad. It is necessary to improve new drippers. Therefore, it is necessary to improve existing products. It is necessary to improve the pressure-resistant, corrosion-resistant, durable, electrochemically anti-cavitation, swing-resistant, reliable, and key-controlled nozzle swing sprinklers with multiple control nozzle switches. The problem that occurs during use is that the body of the swing sprinkler is often swung and skewed. The reason is that the plastic product is too light. In order to further increase the spraying area, an ultrasonically controlled swing sprinkler with adjustable area that can increase the height of the sprinkler is designed. Summary of the invention

[0086] Operators often encounter troubles, that is, there is no interface for the water source, but only a faucet. The faucet needs to be removed in order to connect the sprinkler timer. But sometimes there is no suitable tool at hand, and sometimes the faucet is difficult to remove due to rust over time, and it has to be installed again after use; the combination of the swing sprinkler with an energy-saving sprinkler timer with a multi-purpose interface and a water distributor is energy-saving and water-saving for garden irrigation. There are many existing products, and none of them is perfect; there is a certain type of sprinkler, and water is sprayed out through the only small square through hole set on the sprinkler cap as the water spray port, and its disadvantage is that the water spray range is narrow. Another type of sprinkler in the existing product sprays out through a large through hole with half of the side open on the sprinkler cap, and its disadvantage is that the water spray range is only half of the side, and there cannot be a 360-degree all-round irrigation effect. The regulation of drip irrigation water output, irrigation according to the needs of plant growth, and efficient water-saving irrigation that saves water resources are long-standing problems in the industry at home and abroad. It is necessary to improve new nozzles, so it is necessary to improve existing products. Improved pressure-resistant, corrosion-resistant, durable key-controlled nozzle swing sprinklers with adjustable spray angles are needed, as well as sturdy and non-skewing metal base swing sprinklers with adjustable area. The problem in use is that the body of the swing sprinkler is often swung and skewed. The reason is that the plastic product is too light. In order to further increase the spraying area, a modified metal base swing sprinkler with adjustable area that can increase the height of the sprinkler was thought of. It is troublesome to connect water and electricity at the beginning, but it is convenient to remotely control a large number of units.
