Spraying pipe capable of freely combining area and flow

Abstract

The invention discloses a spraying pipe capable of freely combining the area and the flow continuously improved. A commutator of a non-involute gear set is adopted; a plurality of rocking nozzles 59 are arranged in a parabola arc with different heights; a runner of each rocking nozzle is provided with a petal channel with a multi-petal plum blossom form; the rocking nozzles adopt special polyurethane TPU, are pretreated within 100 DEG C for a plurality of houses, are molded, and are subjected to aftertreatment which is the isotope irradiation treatment for a plurality of hours, so that the rocking nozzles are uniform as far as possible, and are not liable to age, harden and crack to achieve durability and long flexibility; the heights of slide blocks are in an isometric logarithmic spiral with the characteristic of the same pressure angle in each place, so that the different height positions of the rocking nozzles are uniformly pushed as far as possible to change the angle; adjusting gears 63 with worms and fan tooth adjusting buttons 62 are matched with the slide blocks; or the slide blocks are matched with adjusting arc groove fans 64 with arc pin grooves of the isometric logarithmic spiral with the characteristic of the same pressure angle in each place for uniform pushing as far as possible.

Description

technical field [0001] The invention relates to a control method of water flow used for environmental protection and landscaping, which is an electromagnetic flowmeter and a flow rate meter for a high-performance anti-fouling swing sprinkler and a new type of energy-saving impeller suspension shaftless support for energy-saving agriculture and forestry irrigation. Adjustable dripper, 360-degree sprinkler, fine-tunable screw ring size and thread pitch connector, and energy-saving sprinkler irrigation timer and water distributor, and improved area and flow rate on the basis of arc-shaped groove spray angle adjustable swing sprinkler Free combination spray pipe. Background technique [0002] The desire to pursue environmental protection and landscaping is endless; there are also many patents on the control method of watering water flow, and the timing switch of garden sprinklers controlled by both sides of the long axis, such as patent US7252113B2, and Patent ZL200820120164.8 ...

Problems solved by technology

Existing products vary, and none of them are perfect; there is a certain nozzle (55ac), such as Figure 31 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ac) through the matching components and then sprayed out through the only small square hole provided on the nozzle cap as the water nozzle (55a3c). Its disadvantage is that the range of sprayed water is narrow, and it cannot have a 360-degree all-round irrigation effect.

Another nozzle (55ad) for existing products, such as Figure 32 As shown, the water is connected to the nozzle seat (55c) of the certain nozzle (55ad) through the matching components, and is sprayed out through the large through hole opened on the half side of the nozzle cap as the water nozzle (55a3d) , its shortcoming is that the range of sprayed water is only half, and cannot have a 360-degree all-round irrigation effect

The existing electromagnetic flowmeter is made based on Faraday's principle of electromagnetic induction. When the conductor cuts the magnetic force line in the magnetic field, an induced potential proportional to the liquid flow rate is generated, and is detected by the electrode in contact with the liquid, so that it is converted by the cable. After intelligent processing, communication and control between the flow data and the computer are realized. The existing electromagnetic flowmeter includes a measuring tube, an inlet flange, an outlet flange, electrodes, an excitation coil, a measuring tube housing, a circuit board and a display. The device, in which the measuring tube, inlet flange, outlet flange and measuring tube housing are all made of metal materials, the disadvantages of using metal materials are: the weight of the entire flowmeter is relatively large, it is inconvenient to install and maintain, and usually requires multiple people Completion of cooperation will affect work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive

The water inlet chamber in the pipe body is divided into an upper chamber and a lower chamber by the middle partition, and the upper chamber is equipped with a plurality of flexible nozzles fixed on the middle partition and flexible nozzles mounted on the middle partition. The sliding block, and creatively designed a multi-level step or slope structure on the sliding block, and designed multiple through holes on the multi-level step or slope, so as to facilitate the top of the flexible nozzle installed at multiple equal heights. Protruding from the sliding block, due to the particularity of the step structure or the slope structure, the heights of the tops of the multiple flexible nozzles protruding from the through holes are different, and the bottom of each flexible nozzle is sealed and communicated with the bottom. cavity, then the axial reciprocating movement of the sliding block can drive the top of the flexible nozzle to adjust the tilt at different angles, in order to realize the flexible adjustment of the spray angle of the spray pipe. However, the commercially available spray pipe is not ideal in practice, and the flexible nozzle is easy to adjust. Aging, hardening and cracking, the structure of the steps or inclined planes is pushed forward and backward, and the multiple tubes are sometimes squeezed and warped, and the force is uneven, which cannot be durable. The resistance of the squeezed section of the flexible nozzle flow channel is too large, and the effect is not good.
