Description

Tube type axial flow generator

This creation is about a tubular axial flow generator, especially a power generation mechanism that uses a three-way pipeline combined with a generator to form a power generation mechanism that can adjust the water flow rate and effectively reduce the friction loss of the water flow.

In the ROC Patent Publication No. M448565, a "hydrogenerator" is disclosed, which includes: a water channel in the shape of a tee, a screw rod, and an electric power generating device; the water channel has a water conveying section and a vertical connection in the The water inlet section on one side of the water delivery section, the screw rod is arranged on the water delivery section of the water channel, the screw rod is provided with a screw blade, and the other end of the screw rod away from the screw blade is a power Input end, the power generation device is arranged outside the water channel and connected to the power input end of the screw rod. When the water source flows through the water delivery section through the water inlet section of the water channel, it will drive the screw rod to rotate, causing the screw rod to rotate. The power input terminal is transmitted to the power generating device to generate power.

The above structure sets the generator outside the water flow path, so in use, in addition to avoiding water damage caused by the direct impact of the water flow on the generator, it can also prolong the service life of the generator; When the blade is installed, a turbulent water flow will be formed due to the impact. Such a turbulent water flow will easily form strong friction with the inner wall of the water channel and cause resistance, which will reduce the force of the water flow to move the spiral blade and affect the overall power generation efficiency.

In addition, the Republic of China Patent Publication No. M259848 discloses an "improved structure of a hydroelectric generator" comprising: a lower seat, an upper seat, a top cover, a generator set and a rotor rotating mechanism; The water flow is introduced into the water inlet to impact a blade wheel of the rotating mechanism to rotate, and a magnetic ring is arranged on the coaxial center to magnetically attract a rotor to rotate, so that there is a magnetic field effect between the stators (coils) fixed on the upper seat to generate electricity.

One of the cylinder walls is provided with a slit groove, and a water outlet is formed on the periphery of the cylinder wall. In this way, the excess water can be discharged from the water outlet to avoid affecting the rotation of the internal vane wheel.

In this case, the lower seat and the upper seat are combined to form a water channel similar to the aforementioned three-way shape, which can also prevent the generator set from being directly located on the water flow path. In addition to the service life of the generator; because the water flows in a right-angle lateral flow inside the lower seat, it will not only impact the side wall of the flow channel to form a turbulent water flow, but also form a great frictional resistance on the bottom of the lower seat. , affecting the overall power generation efficiency.
