Sprinkling angle-adjustable swinging sprinkler with arc chutes

Abstract

A sprinkling angle-adjustable swinging sprinkler with arc chutes is a water communicating wet type commutator. A gear set is of a wet type, the gears of the gear set are restrained and highly precise. A right shifting chute and a left shifting chute, of a driving plate (598), with gradually reducing inclined angles are sleeved outside each swinging sprayer (59) of the sprinkling angle-adjustable swinging sprinkler. Four driving plates (598) are employed, and each two share a shifting gear with a handle. and a right shifting chute and a left shifting chute with gradually reducing inclined angles are sequentially arranged on each driving plate (598). Each shifting chute is a section of a logarithmic spiral line, of which the pressure angles at each part are equal to form the sprinkling angle-adjustable swinging sprinkler, with arc chutes, of which the precision is high and the angle is accurate. The problems that reversing is difficult and unreliable and sprinkling angle is inaccurate are solved.

Description

technical field [0001] The invention relates to a control method of water flow for environmental protection and landscaping, which is a high-performance anti-fouling swing sprinkler and a water-saving method, and an electromagnetic flowmeter including a new type of energy-saving impeller suspension shaftless support for energy-saving agriculture and forestry irrigation And circuits and water-saving methods, including flow-adjustable drippers, 360-degree nozzles, connectors with fine-tuning thread ring size and pitch, and energy-saving sprinkler timers and water distributors with multi-purpose interfaces. Swing sprinkler with adjustable sprinkling angle. 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 ad...

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, the 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 wire, a measuring tube housing, a circuit board and The display device, in which the measuring tube, the inlet flange, the outlet flange and the 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, and it is inconvenient to install and maintain. The work is completed with the cooperation of people, which affects work efficiency; and the cost of metal materials is high, making the price of the finished flowmeter more expensive
