Embodiment 1

[0050] Embodiment 1 - the use method of this device

[0051] When in use, fluids such as water or gas are injected through the upper end of the diversion pipe, part of the fluid enters the diversion pipe, and part of the fluid enters the front pipe. Two pipes flow out and fall into the left water cup and the right water cup respectively. Due to the leverage and the unbalanced water volume in the water cup, the left water cup and the right water cup will move up and down between the high position and the low position. The movement principle is as follows: the water cup at the low position The hole cover of the water cup is lifted up by the bottom of the support frame, exposing the water outlet hole of the water cup. This will cause the amount of water in the lower cup to decrease, and the weight of the higher cup will be heavier than that of the lower cup, so that the high cup will drop and drive the low cup at the other end of the lever to rise, forming a new high cup and a lo...

Embodiment 2

[0052] Embodiment 2-mechanical energy is converted into the conversion efficiency of electric energy

[0053] It is known that the number of turns of a single induction coil is 1000, and the resistance is 48Ω. After testing, under the flow conditions of 0.833kg / s, flow velocity 0.088m / s, and inflow pipe diameter 11cm, it can be known that the power P of the water flow is, a coil is connected in series with a 3kΩ voltmeter to generate a peak voltage of 1.8V; Calculated power supply power is, then the conversion efficiency = 33%.

Embodiment 3

[0054] Embodiment 3 - the relationship between the total water inflow, the ratio of the water flow in the pipeline before entering to the total inflow, and the working cycle

[0055] For the swing period diverter, the flow rate at the water inlet is q, and the ratio of the water flow entering the front pipe to the total water flow is α. Given the mass of the baffle, the inclination angle θ of the baffle, the length L of the baffle, the mass of the hole cover, the internal cross-sectional area of ​​the shunt pipe A, and the capacity of the cup full of water is V,

[0056] Period T is where q' is the flow in a bucket, Substituting into the formula of period T, we get

Abstract

The invention discloses a swing low-speed fluid generator. The swing low-speed fluid generator consists of two parts of a swing shunt and a sing piston generator. The swing low-speed fluid generator breaks through the limitation that a traditional shunt cannot generate periodic liquid or gas, and uses a water cup, impacted by the gas or the liquid to swing, for driving a baffle plate to separate the liquid to skillfully realize periodic shunt effect; the power of the device is totally from kinetic energy or potential energy of water or the gas; the gas or the liquid only needs to be transferred to a higher energy point of the device; compared with a periodic shunt realized by an electric control valve, the device needs no additional input energy; and a piston structure is used, so that the kinetic energy of the fluid can be used more sufficiently and more efficiently in power generation by low-speed fluid, and the loss of useful energy is reduced.
