Wave linear generator unit

The invention discloses a wave linear generator unit which is composed of a seal cap (1), a shell (2), a coil (3), an elastic cap (4), a rotor fixed shaft (5), a pulley block (6), a magnet (7), a rotor fixed groove (8) and a buoyancy ring, wherein the rotor fixed shaft (5), the pulley block (6) and the magnet (7) form a rotor; the magnet is sleeved on the rotor fixed shaft; the pulley block is provided with at least two groups of pulleys, namely 4 pulleys, and the pulleys are arranged on the two sides of the rotor fixed shaft; the rotor slides in the rotor fixed groove (8) through the pulleys, and the two groups of pulleys are mutually matched with the groove; and the coil is a virgulate coil (3) of a linear generator, the elastic cap is arranged at the end part of the rotor fixed shaft and is fixed with the pulley block and the magnet into a whole, and the buoyancy ring is sleeved on the outer part of the shell. The output power of the wave linear generator unit is over two times of that of the structure of
