Abstract

A ship-borne wave-activated pendulum generator driven by turbulent motion comprises: a base (1), a pendulum generator (2), a pendulum rod (3), a pendulum bob (4), a sliding sleeve (5), and a damping spring (6). An inertial vibration member, which consists of the damping spring (6) and a mass block consisting of the pendulum rod (3) and the pendulum bob (4), absorbs wave energy which causes a hull (1000) to undergo turbulent motion. The wave energy is converted into unidirectional rotation of a generator rotor (25) by means of a one-way bearing mechanism, and the mechanical energy is temporarily stored in the form of rotational inertial energy. At the same time, a coil of a generator stator (24) couples with a magnetic field of the generator rotor (25) and a pulsed induced electric potential is generated. Finally, a rectification circuit and an energy storage battery are used to convert the pulsed electric potential into a stable voltage and power a ship-borne electrical load device. The wave-activated generator has a simple structure and high energy conversion efficiency and volume power density, is reliable, and is low-cost.

The support table (1) is divided into air suction grids by means of a composite structure consisting of a valve block array layer (13) driven magnetically, a grid layer (14), and a non-woven fabric layer (15), and the air suction grids are on or off in a mutually independent manner. When the support table (1) is used as a support table for a tabletop cutter, the valve driving module (2) is provided above the support table (1) and moves along with a cutter head (8), and a magnetically driving transverse bar of the valve driving module (2) that moves along with the cutter head (8) controls air valves (13101) of valve blocks in the support table (1) to be on or off to dynamically communicate valve blocks (131) in a strip-like local region of the support table (1) with an extractor fan (9). The invention limits an effective air suction cross section of the support table (1) to be within a strip-like local region near the cutter head (8), thereby achieving, with a reduced air evacuation power, a negative pressure-based holding effect in the local region of the support table. The exposed magnetic transverse bar-driven valve array support table has advantages of structural simplicity, a low manufacturing cost, a superior negative pressure-based holding effect, low noise, and low power consumption for production and operations.
