Description

Improved automatic sprinkler with triangular support

Technical Field

The invention relates to an automatic sprinkler with a triangular bracket for irrigation water flow for environmental protection and landscaping, in particular to a high-performance dirt-proof water-saving method, an electromagnetic flowmeter and a circuit with an energy-saving novel impeller suspension shaftless bracket for agriculture and forestry irrigation and a water-saving method.

Background

The desire to pursue environmental protection and landscaping is endless; there are several patents relating to the control of irrigation flow, such as patent US7252113B2 and patent ZL200820120164.8, and there are many patents relating to water-saving sprinkling and drip irrigation, such as CN103651053a and 012055360, etc., each for thousands of years. The existing products are different and sufficient, and are not all perfect. The disadvantage is the range of water sprayed; only half, the water mist spray can not have 360-degree omnibearing irrigation effect, and the water mist spray has no artistic effect of flying; furthermore, the spray drip irrigation water regulation and the water regulation irrigation and the water saving efficient water-saving irrigation according to the plant growth demands are the old and difficult problems at home and abroad in the industry, how to prevent dirt of a sprinkler head is also the old and difficult problem, so that the existing product needs to be improved, but the movable sprinkler head consumes the kinetic energy of water and is easy to be in dynamic failure and has higher cost, the product can be further improved, and the inventor is expected to improve and specially mix certain devices related to manufacturing in foreign countries such as Israel of Switzerland, and the invention is assisted to enable the product to be further arranged above; however, even if the timer and the sprinkler are good, the interface is not good; in practice, some are pipe connectors, while others are unthreaded faucets, the method of adding a multipurpose connector has been used, and the method is still applicable to faucets and some connectors, but not applicable to many connectors; the reason is that a garden has a plurality of interfaces which are worn or corroded, the threads of the interfaces are slipped, are not connected or are not connected tightly, and are leaked, and the threads of the interfaces are almost mixed together; it is not easy to replace a large number of interfaces; even if the joint is replaced, a plurality of threads on the raw water pipe are also provided with sliding teeth, the replaced joint is worn or corroded, and the new joint also has a plurality of problems of upper tolerance, lower tolerance and out-of-tolerance, no connection or no connection with the sliding teeth; the problem that the operation of screwing a thread can be completed only by screwing a small half turn of a hand tool and screwing a plurality of small half turns of the hand tool is slow; whether used in sprinkler timer and irrigation water dispenser practices, improvements in product to irrigate gardens are desirable. Rotary sprinkler heads of gardening and agricultural liquid sprinklers have been widely used for sprinkling irrigation of a plurality of operations such as farmlands, forestry nurseries, plastic greenhouses, urban roadsides, lawns, flower beds, greening and the like in a manner selected by people's preference. One of the serious problems worldwide is that fresh water resources are short, and water-saving sprinkling irrigation is becoming an important means for planting crops and garden flowers and plants. The sprinkler head, in particular the rotary sprinkler head, is a key device of a sprinkler system, and the performance of the sprinkler head directly influences the sprinkler effect. In the existing plastic sprinkler head, the pressure of several parts of a plastic water spraying target is quite high and is easy to break frequently; the adjusting and positioning of the reversing positioning block are easy to loosen after a long time; it is conceivable that friction between the rotary mandrel and the hexagonal head is reduced to ensure reliable reversing, and that the seal between the rotary mandrel and the hexagonal head is satisfied to prevent leakage, which are all the major and difficult problems of the sprinkler head. Furthermore, the nozzles of the sprinkler head, in particular the spray cores, also affect the uniform quality of the spray. In order to overcome the defects of working states caused by all mechanisms of the sprinkler head in the prior art and to invent several different types of sprinkler heads, the inventor summarizes working experiences at home and abroad for many years and makes various designs and improvements; just as improvement is perfected and is never completed, the human pursuing the perfection of the invention is never in full; the spray irrigation heads with various rotations are found after long-term tests, and are arranged on the spray irrigation seat, and the spray irrigation heads are related to the perpendicularity of a common rotating shaft of the spray irrigation head and the spray irrigation seat and the nozzle shape of the common rotating shaft except the relation of wind direction, tolerance, water pressure and adjustment; thus, a sprinkler with adjustable verticality and adjustable rotation speed of horizontal bubbles and an automatic sprinkler with a rotary wing nozzle and a triangular bracket matched with an automatic timing device are generated; various schemes of gradual improvement and perfection are tried, or a plastic sprinkler head or a metal sprinkler head is used for regulating rotation speed and a sprinkler with a horizontal bubble and adjustable verticality is used, but a new problem is solved, various original sprinklers and sprinkler heads are changed into a plurality of ones without separation, the moving sprinkler heads are used for rotating or swinging to spray water, the moving sprinkler heads are provided with only one nozzle, water is sprayed once only after one circle of slow swallowing, the total spraying time is too long, a part of water kinetic energy is consumed when the sprinkler heads move, and the working efficiency is low; and the moving parts of the moving mechanism of the moving sprinkler head are easy to wear and sometimes are easy to be blocked so as to be dynamically malfunctioning; moreover, the cost is high due to more moving parts of the moving sprinkler head; the disadvantage of the above spray nozzles is the internationalization difficulty. According to the requirements of high-grade flower colors and noise reduction markets, the novel and improved noise reduction water target for the automatic triangular bracket sprayer realizes the dual purposes of spraying flower colors, spraying and viewing.

The improved automatic triangular bracket sprayer is characterized in that an oscillating ring (m 8 c) and a noise reduction matrix (m 8 f) are arranged on a water spraying target (m 8) on a spraying head of the sprayer; the oscillating ring (m 8 c) is a plurality of spiral turns with slightly larger ends and slightly smaller middle parts of which the outer contour line of the side scanning is similar to that of a logarithmic spiral, and the cross section of the spiral turns adopts a triangle; the noise reduction matrix (m 8 f) is composed of a plurality of dense elliptical holes with different sizes arranged at the upper part, the middle part and the lower part of the water spraying target (m 8), the parabolic water baffle (m 21) and the parabolic plate (m 21 b) so as to achieve the functions of spraying water, scattering, atomizing and noise reduction.
