Water yield proportion adjustment devices

Abstract

The invention discloses water yield proportion adjustment devices. At least two water yield proportion adjustment devices are arranged; each water yield proportion adjustment device comprises a cavity enclosed by a shell, one end of each cavity is provided with a water inlet, and the other end of each cavity is provided with an end cover; each water inlet is provided with a water retaining piece, each water discharging cavity is provided with a water outlet, each water drainage cavity is provided with a water drainage opening, water inlets of the water discharging cavities communicate with the water discharging cavities, and water inlets of the water drainage cavities communicate with the water drainage cavities; the middles of the water retaining pieces are provided with rotating shafts driven by control motors, the rotating shafts are provided with rotating water retaining pieces, all the water inlets are connected with a main pipe, water is supplied to the main pipe through a water pump driven by a motor, and all the water outlets are connected with numerical control spray heads; along with rotation of the rotating water retaining pieces, the sum of the area of the unshielded water discharging cavity water inlets and the area of the unshielded water drainage cavity water inlets is always the preset value. By means of the water yield proportion adjustment devices, infinite adjustment of the water spraying height of each spray nozzle is achieved, when the water spraying height(s) of a certain or some spray nozzles is (are) adjusted, the water spraying heights of other spray nozzles cannot be influenced, and the cost is low.

Description

Technical field [0001] The invention relates to water supply equipment of a fountain system, in particular to a water output proportional adjustment device. Background technique [0002] The existing water supply equipment of the fountain system mainly has three structures: the first structure is that a motor drives a water pump, and the water pump supplies water to multiple nozzles through the main pipeline. This basic structure can be adjusted by adjusting the motor speed. The spray height of each nozzle can be changed together, but the independent real-time change of the spray height of each nozzle cannot be realized, which limits the shape and change of the fountain. The second structure is to add each nozzle to the above basic structure. A speed-adjusting motor and a water pump. Although this improved structure can realize independent and real-time changes in the spray height of each nozzle or change together, its cost is too high, and it is adjusting one (or some) of the no...

[0002] The water supply equipment of the existing fountain system mainly has three structures: the first structure is a water pump driven by a motor, and the water pump supplies water to multiple nozzles through the main pipeline. This basic structure can be adjusted by adjusting the speed of the motor. The water spray height of each nozzle can be changed together, but it is impossible to realize the independent real-time change of the water spray height of each nozzle, so that the shape and change of the fountain are limited; the second structure is to add configuration to each nozzle on the basis of the above basic structure A speed-regulating motor and a water pump, although this improved structure can realize the independent real-time change of the water spray height of each nozzle or change together, but its cost is too high, and it is difficult to adjust one (or some) of the nozzles. When the water spray height is changed, due to the change of the water output of the nozzle, the total water output in the main pipeline changes, and the water pressure in the main pipeline changes, which affects the chain change of the water spray height of other nozzles, resulting in the other nozzles. The water spray height is unstable; the third structure is to add a solenoid valve to each nozzle on the basis of the above basic structure. This improved structure can only realize the switch control of the water spray of each nozzle, but cannot realize Stepless adjustment of the spray height of each nozzle
