Description

Technical Field

[0001] The present invention relates to an automatic sprinkler with a triangular bracket for irrigation water flow for environmental protection and gardening, a high-performance anti-fouling water-saving method, an electromagnetic flowmeter and a circuit and a water-saving method containing an energy-saving new impeller suspended shaftless bracket for energy-saving agriculture and forestry irrigation, including a flow-adjustable dripper, a 360-degree nozzle, a joint with fine-adjustable thread ring size and pitch, and a combination of an energy-saving sprinkler timer and a water distributor with a multi-purpose interface, as well as a swing sprinkler with adjustable spraying angle and a plastic sprinkler head and a metal sprinkler head for a liquid sprinkler for gardening, horticulture and agriculture. A method for adjusting the rotational inertia moment of improved water target adjustable reversing positioning is provided for the sprinkler head and the sprinkler. A color light triangular bracket automatic sprinkler with color light and a nozzle pin of a modified pin-type sprayer are now developed, both of which belong to the technical field of sprinkler heads in spraying devices. Background Art

[0002] The desire to pursue environmental protection and landscaping is endless; there are many patents on the control method of irrigation water flow, such as patent US7252113B2 and patent ZL200820120164.8, and there are many patents on water-saving sprinkler irrigation and drip irrigation, such as CN103651053A and 012055360, etc., each with its own advantages. Existing products are numerous and none of them is perfect. The disadvantage is the range of the water sprayed; it is only half, and there can be no 360-degree all-round irrigation effect, and it is difficult to have the artistic effect of water mist and water splashes; in addition, the regulation of water output from spraying and drip irrigation, the regulation of irrigation according to the water demand of plant growth, and the efficient water-saving irrigation that saves water resources are long-standing problems in the industry at home and abroad, and how to prevent the sprinkler nozzle from dirt is also a long-standing problem. Therefore, it is necessary to improve the existing products. The market needs a swing sprinkler with adjustable spray angle, but the motion sprinkler head consumes water kinetic energy and is prone to dynamic failure and has a high cost. This type of product can be further improved. Thinking of the eight countries and thousands of patents that the inventor has obtained, the inspiration of other people's jade and certain devices involved in manufacturing in foreign countries such as Switzerland and Israel, they can be improved and specially blended, and then supplemented with innovation to make the product a higher level; it is not enough if the sprinkler is only easy to use but the interface is not good; In practice, some are pipe interfaces, while others are faucets without threads. The method of adding more interfaces has been used. It works for faucets and some interfaces, but not for many interfaces. The reason is that many interfaces in a garden are worn or rusted, and the threads of many interfaces are loose, and they cannot be connected or connected tightly, and they leak after being connected. The threads of many interfaces are similar but different threads are mixed together. It is not easy to replace a large number of interfaces. Even if they are replaced, many threads on the original water pipes are also loose, and the replaced interfaces will also be worn or rusted, and the new interfaces also have upper or lower tolerances and out-of-tolerance, and cannot be connected or connected tightly, and have many problems such as loose threads. There is also the problem of slow operation that a hand tool has to be turned a small half circle, then changed hands to turn a small half circle, and then turned many times to complete a thread. Whether it is used for sprinkler timers or watering water distributors, improved products are hoped to be available for watering gardens. The rotating sprinkler head of the horticultural and agricultural liquid sprinkler has been widely used for irrigation of farmland, forestry nurseries, plastic greenhouses, urban roadsides, lawns, flower beds, greening and other diversified operations in the way chosen by people's preferences. One of the major problems in the world is the shortage of fresh water resources. Water-saving sprinkler irrigation has gradually become an important means of planting crops and garden flowers. Sprinkler heads, especially rotating sprinkler heads, are key equipment in sprinkler systems, and their performance directly affects the effect of sprinkler irrigation. In existing plastic sprinkler heads, the plastic water target is often prone to breakage due to high pressure at several places; the reversing positioning block is prone to loosening after a long time; between the rotating mandrel and the hexagonal head, it is conceivable that the friction must be reduced to ensure reliable reversing, and the sealing between the two must be satisfied to prevent leakage. These items are indeed the most difficult problems for sprinkler heads. In addition, the nozzle of the sprinkler head, especially the spray core, also affects the uniform quality of the sprayed material.In order to overcome the shortcomings of the working state of the various mechanisms of the sprinkler heads in the prior art, and also to invent several different types of sprinkler heads, the inventors have summarized many years of work experience at home and abroad and made a variety of designs and improvements; just as improvement and perfection are endless, the pursuit of perfection of invention by humans is endless; after long-term testing, it is found that various rotating sprinkler heads are installed on the sprinkler seat. In addition to being related to wind direction, tolerance, water pressure, and deployment, they are related to the verticality of the common rotating shaft of the sprinkler head and the sprinkler seat and the shape of the nozzle; thus, a sprinkler with horizontal bubbles, adjustable verticality and adjustable rotation speed, and a rotating wing nozzle with an automatic timing device and a colorful light triangle bracket automatic sprinkler came into being; after trying a variety of gradually improved and perfected solutions, Or use plastic sprinkler heads or metal sprinkler heads to adjust the rotation speed and have sprinklers with horizontal bubbles and adjustable verticality. However, when one problem is solved, a new problem arises. All the original sprinklers and sprinkler heads are the same. They all use moving sprinkler heads to rotate or swing to spray water. They all have moving sprinkler heads and only one nozzle. They must rotate slowly for one circle to spray water. They have to rotate many circles. The total spraying time is too long. The sprinkler head consumes part of the water kinetic energy to move, and the work efficiency is not high. Moreover, the moving mechanism of the moving sprinkler head has many moving parts, which is easy to wear and sometimes easy to get stuck and fail dynamically. Moreover, the moving sprinkler head has many moving parts, which leads to high cost. To overcome the shortcomings of the above sprinkler heads, it is a long-standing problem. In response to the market demand for high-end colors and noise reduction, the newly developed color light triangular bracket automatic sprinkler uses noise reduction water target and color light to achieve spraying and viewing. A new type of small, easy-to-insert needle-type sprayer is also needed in production. The sprayer nozzle is equipped with a rotating needle to achieve a longer range. Summary of the invention

The water outlet (15) originally has six equally distributed reinforcing ribs inside. In order to further improve the water spraying effect, the internal channel is specially changed into a parabolic channel, and a part of the original six reinforcing ribs is still retained, reducing the idle space between the original reinforcing ribs that is easy to cause backflow. The parabolic channel increases the cohesion and fluidity of the spraying; the reinforcing ribs are multiple, at least 3; on the one hand, they strengthen the strength of the water outlet, and on the other hand, they have the auxiliary diversion effect of strengthening the sprayed water; the two angle controllers, namely the reversing positioning blocks (m5) installed on the hexagonal head fixed sleeve (m4), are prone to loosening after multiple collisions; for this reason, a convex block is provided in the reversing positioning block (m5), and a plurality of circumferential pits are added at the position of the hexagonal head fixed sleeve (m4) where the reversing positioning block (m5) is placed to prevent loosening; the thrust bearing gasket (m3) has a plurality of ball-loading pits on its first surface, at least three, or 12, or 3-100, so as to install the thrust bearing balls (m3c) therein;The ball loading pit is preferably a deep pit, the depth of which is greater than the radius of the thrust bearing ball, so that there is a larger volume for loading the ball and the ball is not easy to escape; its second surface is provided with a circumferential inclined surface, so that it can be squeezed and self-centered with the chamfered inclined surface at the end of the hexagonal head fixed sleeve (m4) and is not easy to tilt, thereby reducing; in order to further enhance the reliability of reversing positioning, an improved stainless steel toggle spring (m19) is installed on the short switch (m18), and in order to enhance the instantaneous condensed explosive force, one or more coils of springs are provided at the lower part of the intersection of the left and right rods of the short switch, so as to collide with the two reversing positioning blocks (m5) installed on the hexagonal head fixed sleeve (m4) to trigger the reversing.

The water outlet (15) of the spray head is provided with a rotating wing (m15), which is in a tower-like spiral shape with a larger bottom and a smaller top. The rotating cross section (f15) of the rotating wing (m15) has a convex surface (f15c) on the upper side and a concave surface (f15d) on the lower side, and a concave surface (f15d) on the lower side. The inner end (f15b) has a large curvature and the outer end (f15a) has a small curvature, thus forming a streamlined rotating wing of the rotating cross section (f15), so that the automatic sprinkler of the colorful light triangular bracket uses the streamlined rotating wing of the rotating cross section (f15) of the rotating wing provided on the water outlet (15) of the spray head to form a rotating wing nozzle effect to achieve the dual purpose of spraying and viewing;In order to overcome the shortcomings of various sprinkler heads and solve the long-standing problem of internationalization, in response to the market demand for high-end colors and noise reduction, the sprayer nozzle is innovatively modified with a rotating pin to achieve a longer range, and the use of noise reduction water targets and colored lights to achieve the dual purpose of spraying colors and spraying noise reduction for viewing. ;

[0005] The modified nozzle pin color light sprayer is designed to overcome the shortcomings of various sprinkler heads and solve the long-standing problem of internationalization. In response to the market demand for high-end colors and noise reduction, the noise-reducing water target and color light are innovatively improved to achieve the dual purpose of spraying colors, spraying, noise reduction and viewing. The highlight is that the parabolic water baffle (m21) is still installed on the water target (m8); in order to block the water sprayed from the water outlet and spread the water parabolically, the parabolic water baffle (m2 1) is provided with a parabolic plate (m21b), and the parabolic plate (m21b) provided on the parabolic water baffle (m21) is arc-shaped and approximately parabolic; in order to better block the water sprayed from the water outlet and make the water parabolically transformed into a mist mixed with water and gas to diffuse and spread out for viewing effect and noise reduction effect, the colorful light triangular bracket automatic sprayer has the bright spot that an oscillation circle (m8c) and a noise reduction matrix are provided on the water target (m8) Array (m8f); the oscillation circle (m8c) is a spiral multi-turn with a similar side scanning outer contour line and slightly larger ends and slightly smaller middle part of a logarithmic spiral. The cross section of the spiral multi-turn is triangular, because it has better experimental effect than a circular one. Whether there is a better cross section needs further exploration, so as to achieve more mist by vibrating and shaking to hit water, and also to make use of the characteristics of the logarithmic spiral with equal pressure angles everywhere to strive to hit water evenly from different angles; the noise reduction matrix (m8f) is composed of multiple dense elliptical holes of different sizes arranged at multiple locations of the upper, middle and lower parts of the parabolic water baffle (m21), the water target (m8) and the parabolic plate (m21b). According to international experiments, the elliptical holes have a noise reduction effect on the fluid, so as to achieve the effect of hitting water, breaking up, atomizing and reducing noise by the noise reduction matrix, because the water mist flow has an expansion, compression and expansion process before and after passing through the elliptical holes, which is easy to meet the noise reduction conditions.

[0006] The modified nozzle pin color light sprayer is characterized in that an oscillation circle (m8c) and a noise reduction matrix (m8f) are provided on the water target (m8) on the spray head of the sprayer; the oscillation circle (m8c) is a spiral multi-turn with a side scanning outer contour line similar to a logarithmic spiral, which is slightly larger at the two ends and slightly smaller in the middle, and the cross section of the spiral multi-turn is triangular; the noise reduction matrix (m8f) is composed of a plurality of dense elliptical holes of different sizes arranged at multiple locations of the upper, middle and lower parts of the water target (m8), the parabolic water baffle (m21) and the parabolic plate (m21b), so as to achieve water spraying, dispersion, atomization and reduction. The effect of noise; further improve the ornamental value by setting up a new colored light circuit, a colored light triangle bracket automatic sprayer, characterized in that it is provided with a colored light circuit, the circuit is mainly composed of related components such as a colored light string H, a thyristor VTH, a transistor VT, a potentiometer RP, a piezoelectric ceramic piece B, etc. on the sprayer, and the thyristor VTH adopts a small plastic-sealed unidirectional micro-trigger thyristor 2N6565 or MCR100-8 type with a small trigger current, etc. The 220V alternating current of the water and electricity supply source is rectified by the colored light string H and the diode VD1-4 to become a pulsating voltage of about 200V, which is added to both ends of the thyristor VTH as the positive voltage required for the thyristor VTH to work. To the anode voltage; the other path is divided by the first resistor R1 and the fourth resistor R4, and filtered by the capacitor C1, and a stable DC voltage of about 3V can be obtained at both ends of the capacitor C1 as the working voltage of the transistor VT; the potentiometer RP is a sound control sensitivity adjustment potentiometer, and the potentiometer RP can be adjusted according to the environment to make the transistor VT just in the critical conduction state. At this time, the gate of the thyristor VTH is short-circuited by the transistor VT and the trigger voltage cannot be obtained, so the thyristor VTH is in the off state, and the current flowing through the colored light string H is extremely small, and the colored light string H does not light up; when there is human voice and spraying sound, the piezoelectric ceramic piece B picks up the environmental sound wave signal and converts it into phase The corresponding audio signal is added to the emitter junction of transistor VT; the negative half cycle of the strong signal causes transistor VT to exit the conduction state and enter the amplification state, so the collector potential of transistor VT increases. The stronger the audio signal, the higher the collector potential of transistor VT. When it reaches the trigger level of the gate of thyristor VTH, thyristor VTH is turned on and the colorful light string H lights up. When the signal is weak, the collector output level of transistor VT is lower than the trigger level of the gate of thyristor VTH. Thyristor VTH is turned off when the alternating current passes through zero, so the colorful light string H can flash with the strength of the ambient sound wave signal, forming a colorful light viewing artistic effect.

The cross section of the spiral multi-turn is triangular, because it has better experimental results than a circular one. Whether there is a better cross section needs further exploration, so as to achieve more mist by vibrating and shaking to hit water, and also to utilize the characteristics of the logarithmic spiral with equal pressure angles everywhere to strive to hit water evenly from different angles; the noise reduction matrix (m8f) is composed of multiple dense elliptical holes of different sizes arranged at multiple locations of the upper, middle and lower parts of the parabolic water baffle (m21), the water target (m8) and the parabolic plate (m21b). According to international experiments, the elliptical holes have a noise reduction effect on the fluid, so that the noise reduction matrix can hit water, disperse, atomize and reduce noise, because the water mist flow has an expansion, compression and expansion process before and after passing through the elliptical holes, which easily meets the noise reduction conditions.

[0081] Advantages: strong and durable, increased spray cohesion and smoothness, triangular bracket is convenient for installation of automatic spraying, using the rotating wing nozzle in combination with the streamlined rotating wing of the rotating cross section (f15) to achieve the dual purpose of spraying and viewing; better blocking the water sprayed from the water outlet and making the water parabolically transformed into a mist mixed with water and gas to diffuse and spread out, which is beneficial to the viewing effect and has a noise reduction effect, and is provided with an oscillation circle (m8c) and a noise reduction matrix (m8f); the oscillation circle (m8c) is a spiral with a side scanning outer contour line similar to a logarithmic spiral, with two ends slightly larger and the middle slightly smaller, and its cross section adopts a triangular shape, which is beneficial to vibration, shaking and beating Water and more mist, so as to utilize the characteristics of the logarithmic spiral with equal pressure angles everywhere to strive to evenly hit water back and forth from different angles; the noise reduction matrix (m8f) is composed of multiple dense elliptical holes of different sizes arranged at multiple locations of the upper, middle and lower parts of the parabolic water baffle (m21), the water target (m8) and the parabolic plate (m21b). According to international experiments, the elliptical holes have a noise reduction effect on the fluid, so that the noise reduction matrix can hit water, disperse, atomize and reduce noise, because the water mist flow has an expansion, compression and expansion process before and after passing through the elliptical hole, it is easy to meet the noise reduction conditions.

[0082] The modified nozzle pin color light sprayer is characterized in that an oscillation circle (m8c) and a noise reduction matrix (m8f) are provided on the water target (m8) on the spray head of the sprayer; the oscillation circle (m8c) is a spiral multi-turn with a side scanning outer contour line similar to a logarithmic spiral, which is slightly larger at the two ends and slightly smaller in the middle, and the cross section of the spiral multi-turn is triangular; the noise reduction matrix (m8f) is composed of a plurality of dense elliptical holes of different sizes arranged at multiple locations of the upper, middle and lower parts of the water target (m8), the parabolic water baffle (m21) and the parabolic plate (m21b), so as to achieve water spraying, dispersion, atomization and reduction. The effect of noise; further improve the ornamental value by setting up a new colored light circuit, a colored light triangle bracket automatic sprayer, characterized in that it is provided with a colored light circuit, the circuit is mainly composed of related components such as a colored light string H, a thyristor VTH, a transistor VT, a potentiometer RP, a piezoelectric ceramic piece B, etc. on the sprayer, and the thyristor VTH adopts a small plastic-sealed unidirectional micro-trigger thyristor 2N6565 or MCR100-8 type with a small trigger current, etc. The 220V alternating current of the water and electricity supply source is rectified by the colored light string H and the diode VD1-4 to become a pulsating voltage of about 200V, which is added to both ends of the thyristor VTH as the positive voltage required for the thyristor VTH to work. To the anode voltage; the other path is divided by the first resistor R1 and the fourth resistor R4, and filtered by the capacitor C1, and a stable DC voltage of about 3V can be obtained at both ends of the capacitor C1 as the working voltage of the transistor VT; the potentiometer RP is a sound control sensitivity adjustment potentiometer, and the potentiometer RP can be adjusted according to the environment to make the transistor VT just in the critical conduction state. At this time, the gate of the thyristor VTH is short-circuited by the transistor VT and the trigger voltage cannot be obtained, so the thyristor VTH is in the off state, and the current flowing through the colored light string H is extremely small, and the colored light string H does not light up; when there is human voice and spraying sound, the piezoelectric ceramic piece B picks up the environmental sound wave signal and converts it into phase The corresponding audio signal is added to the emitter junction of transistor VT; the negative half cycle of the strong signal causes transistor VT to exit the conduction state and enter the amplification state, so the collector potential of transistor VT increases. The stronger the audio signal, the higher the collector potential of transistor VT. When it reaches the trigger level of the gate of thyristor VTH, thyristor VTH is turned on and the colorful light string H lights up. When the signal is weak, the collector output level of transistor VT is lower than the trigger level of the gate of thyristor VTH. Thyristor VTH is turned off when the alternating current passes through zero, so the colorful light string H can flash with the strength of the ambient sound wave signal, forming a colorful light viewing artistic effect.
