[0023] In order to make the above-mentioned purposes, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0024] As shown in Figures 1-4 The present application provides a friction power generation device based on water flow impact, which comprises

[0025] A Tesla valve 1, and a cavity is formed in the outer side wall of the Tesla valve 1 at the position of maximum water flow velocity of each loop opening; and

[0026] A paddle mechanism, which is arranged at the cavity and comprises a paddle 2, a rubber sleeve 3 and a spring 4, the paddle 2 is used for swinging when water flows, the rubber sleeve 3 is used for sealing the cavity, and the spring 4 is used for promoting the paddle rod of the paddle 2 to swing back and forth, the end of the paddle rod rubs against the inner wall of the cavity back and forth to generate friction power, the generated electric energy is collected by a capacitor outside the Tesla valve, the capacitor lead wire is in contact with the cavity wall to lead out the electric current, and the electric current is collected by the capacitor.

[0027] In one embodiment, a plurality of cavities are formed in the Tesla valve 1, the cavities are located opposite to each loop opening, and the water flow velocity is maximum at the position of each loop opening. The paddle mechanism further comprises a small ball, the small ball is located at the end of the paddle rod, and the small ball is in contact with the cavity. The inner wall of the cavity and the small ball are both made of metal. The paddle 2 is located at the position of maximum water flow velocity of each loop opening, the small ball at the end of the paddle rod is in contact with the cavity in the Tesla valve 1, and the small ball can move along the cavity wall.

[0028] In this embodiment, the rubber sleeve 3 is installed at the cavity opening in the cavity in the Tesla valve 1 to ensure the sealing property of the cavity. The inner hole of the rubber sleeve 3 cooperates with the paddle rod to play the role of fulcrum fixation for the paddle rod. The spring 4 is embedded in the groove of the paddle rod, the paddle rod is provided with a groove, so that the spring 4 can be fixed on the paddle rod, and the other end of the spring 4 is in contact with the cavity in the Tesla valve 1 to ensure that the paddle rod can swing back and forth.

[0029] In one of the embodiments, the rubber sleeve 3 is installed at the cavity mouth of the cavity. The first end of the paddle rod is installed with the paddle 2, and the second end of the paddle rod extends into the cavity through the rubber sleeve 3.

[0030] The use process of the device is as follows:

[0031] Firstly, the paddle 2 in the paddle mechanism is adjusted to be located at the position where the water flow velocity is maximum at the loop mouth. When the water flow flows into the Tesla valve 1 in the positive direction, the water flow is divided into two ways at each loop mouth and is converged at the next loop mouth, so that the water flow velocity reaches the maximum and drives the paddle 2 to move. The small ball at the end of the paddle mechanism rubs on the cavity wall in the Tesla valve 1 along with the movement of the paddle 2 to generate electricity by friction. The spring 4 embedded on the paddle rod ensures that the paddle can return to the initial position when being impacted by the water flow, so that the paddle 2 can swing back and forth along with the water flow.

[0032] The paddle 2 swings to convert the water flow movement into the friction movement of the small ball, so that the electricity generation operation is more convenient. The spring 4 is used as the device for the paddle rod to swing back and forth, and has the advantages of simple structure and high efficiency.
