Abstract:
A steel rope chain is provided for power transmission, including a plurality of parallel and juxtaposing closed steel ropes to which a plurality of equally-spaced wire rope clips is mounted. The wire rope clips are arranged in a juxtaposed manner and fixed to an elongate thick steel plate to form an array of clip assemblies that secure the steel ropes together. Mating the steel rope chain are a driving wheel and a driven wheel that are selectively made in various forms provided they include spokes having free ends carrying crossbars so that when the driving wheel rotates, the crossbars of the driving wheel are brought into engagement with the clip assemblies to drive movement of the steel rope chain and the steel rope chain in movement brings the clip assemblies into engagement with the crossbars of the driven wheel to cause rotation of the driven wheel.
Abstract:
The present invention provides an electricity generation device using hot gas engine. The device contains a closed container filled with high-pressure gas. The container has an outlet which is connected to a pneumatic or hydraulic cylinder. Hot and cold fluids are sprayed alternatively and repeatedly into the closed container to heat up or cool down the high-pressure gas. As the high-pressure gas expands or contracts, a piston rod of the cylinder is pushed and pulled back and forth so as to produce electricity continuously.
Abstract:
A device of floating wind turbine comprises a floating foundation, wind turbines provided on the floating foundation, and a seabed anchor attached to the floating foundation, wherein the floating foundation is symmetrically provided with two wind turbines; the floating foundation and the two wind turbines are attached to the seabed anchor by tethers, whereby when the wind turbines are driven to generate electrical power, they respectively exert an upward force and a downward force at a center portion of the floating foundation between the two wind turbines; both turbines have an approximately equal speed and output power; whereby the upward force can be counterbalanced by the downward force, so that the wind turbines and the floating foundation can be maintained at a balanced condition.
Abstract:
A device of floating wind turbines comprises a floating foundation, the wind turbine mounted on the floating foundation, and a seabed anchor attached to the floating foundation, wherein the floating foundation is installed with two wind turbines and is attached to the seabed anchor by a tether, the two wind turbines are configured such that one of the two wind turbines has blades rotated in clockwise direction while the other of the two wind turbines has blades rotated in counter-clockwise direction, both turbines have an approximately equal speed and output power; whereby, due to both turbines having an approximately equal speed and output power, the torques existed in the wind turbines can be naturally counterbalanced, such that the wind turbines and the floating foundation can be maintained at a balance.
Abstract:
A rotary one-dimensional barcode reading device includes a motor and a one-dimensional barcode reader attached to the motor shaft so as to allow the reader to rotate with the motor shaft, by which linearity of the light source and the receiver of the barcode reader are converted into circularity to realize direction-diversified linear light sources and receives in various directions. Input and output of power source and signals are performed through electrical brushes. With this arrangement, a one-dimensional barcode in any direction can be properly read and the electronic signal generated by the one-dimensional barcode so read is transmitted through the electrical brushes or in a wireless manner to a computer, a point-of-sale (POS), a personal digital assistant (PDA), and the likes.
Abstract:
A power generator with high power-to-volume ratio includes a plurality of silicon steel plates and air gaps or plastic plates, which are alternately arranged to form adjacent magnetic paths of a stator and a mover or a rotor of a power generator and which have intervals (which are defined by thickness or width of the silicon steel plates or the air gaps or the plastic plates) that are set to be very small, whereby when the mover or the rotor take a movement or rotation by one interval, magnetic flux induced in a magnetic path of the stator around which an induction coil is wound changes magnitude and direction thereof so that through quick changes, the induction coil induces a higher voltage and thus significantly increases power-to-volume ratio of the generator.
Abstract:
A horizontal axis wind turbine with rotatable tower including nacelle and blades. The tower, the blades, and the nacelle are rotatable by following the shift of wind direction so as to align the blades to be facing with the wind direction for enhancing performances thereof. Also can eliminate the gearbox, as compared to the conventional horizontal axis wind turbine that the nacelle is not completely fixed with tower, the present invention is easy to manufacture with reduced costs.
Abstract:
The electricity storage and recovery system. At first, injects high-pressure gas in a high-pressure tank and then, the normal-pressure fluid from a normal-pressure tank is pumped into the high-pressure tank by a motor-driven pump so that the electrical energy is converted to high-pressure potential energy of the fluid stored inside the high-pressure tank. To recover the potential energy back to electrical energy, the high-pressure fluid flows from the bottom of the high-pressure tank to the normal-pressure tank through a turbine. The turbine in turn drives a generator to produce electricity. The pump and the turbine are of a same device running in opposite directions. The motor and the generator are also of a same device running in opposite directions.
