Improved adjustable and swing water sprayer

Abstract

The invention relates to an adjustable and swing water sprayer which is continuously and gradually improved. A diverter of an olinkon gear seat is adopted. Multiple swing sprayers 59 at different heights are arrayed in shapes of parabolic arcs with passageways having petal-type channels. The swing sprayers are made by special polyurethane TPU and formed by pre-processing for hours at the temperature of 100 degrees. The swing sprayers are subjected to post-treatment at the temperature of 90 degrees for hour and laser processing so that the swing sprayers are prevented from hardening and cracking due to aging so that the swing arms are endurable and flexible. The height of a sliding block is an equiangular logarithmic spiral with pressure corners being the same so that different height positions of the multiple swing sprayers can be uniformly squeezed as much as possible to change angles. An adjusting gear 63 and a sectorial tooth adjusting button 62 with coarse threads are matched with the sliding block. Or, an adjusting arc-groove fan 64 of an arc pin groove of the equiangular logarithmic spiral with pressure corners being the same is matched with the sliding block so that different heights can be uniformly squeezed as much 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 drippers, 360-degree nozzles, fine-tuning screw ring size and thread pitch joints, and energy-saving sprinkler irrigation timers and diverters, and improved spraying adjustments based on swing sprinklers with adjustable spraying angles in arc grooves Swing the sprinkler. 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 all adopts the tim...

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.
