A hydrostatic bearing assembly including a bearing and two membrane throttles is provided. The bearing is adapted to be movably disposed on a slide rail and includes two sub-bearing portions that are disposed opposite to each other on two opposite sides of the slide rail. The two membrane throttles are adapted to be connected to a pump. The pump is adapted to supply a fluid through the two membrane throttles to flow between the two sub-bearing portions and the slide rail, and each of the membrane throttles includes a casing and a throttling membrane piece. At least one of the casing and the corresponding sub-bearing portion includes a chamber, an inlet and an outlet communicating with the chamber, and an outlet surface, wherein the pump is adapted to be connected to the inlet, and the slide rail is adapted to be disposed adjacent to the outlet. The throttling membrane piece is being positioned in the chamber covers on the outlet surface.

An abnormal discharge alarm device is applied in a steam trap. The steam trap is installed in a pipeline of a steam system. The abnormal discharge alarm device includes a power generation component and a control circuit. The power generation component receives a fluid discharged from the steam trap and generates a self-generated electric power. The control circuit receives and detects the self-generated electric power to obtain a detection result. The control circuit sends an alarm signal when the detection result is greater than a predetermined threshold value. In addition, the abnormal discharge alarm device may further include a monitoring unit. The control circuit transmits the detection result to the monitoring unit. The monitoring unit obtains an updated threshold value according to accumulated detection results, and determines whether to send an alarm after comparing the updated threshold value with a real-time detection result.

A fire nozzle quick-assembly light is provided, which comprises a frame, a luminous device and an electricity generation device. The luminous device and the electricity generation device are sited to the frame. The luminous device is for illuminating in the fire scene, and the electricity generation device is for providing electricity to the luminous device. The fire nozzle quick-assembly light could depend on fireman's needed to be assembled or removed from the fire equipment quickly and provide high illumination to help extinguish fire, evacuate and lower the possibility that fireman suffers injury in dark environment. When the fire accident happens in the place with sufficient light, fireman does not need the additional illumination at this time. The fire nozzle quick-assembly light could be removed from the fire equipment easily to lower the weight.

This disclosure provides a fluid whirl lighting apparatus, which comprises: a housing; a coil module, disposed on an inner wall of the housing; a rotor, disposed in the housing, provided with a plurality of blades on an inner wall thereof and a magnetic module on an outer wall corresponding to the coil module; a lighting module, disposed on the outer wall of the housing while electrically coupled to the coil module; and an alarm element, electrically connected to the coil module for issuing an alarm; wherein the outer wall of the rotor and the inner wall of the housing define an air-tight space for accommodating a liquid, and the rotor is rotated by a flowing fluid propelling the plural blades for enabling a relative movement between the coil module and the magnetic module for generating electricity; and the lighting module is used for providing illumination in response to the electricity.

Fluid whirl lighting apparatus

The present invention provides a swirly fluid sprinkler comprising a sprinkling body, a fluid guide, and an electrical generator. The fluid guide disposed inside the fluid inlet of the sprinkling body includes a plurality of swirl channels for dividing a fluid flow into a plurality of swirly fluid flows. The electrical generator disposed inside the sprinkling body and opposite to the fluid guide has a plurality of blades disposed on the top thereof. Each of the blades has an inclining angle wherein the blade surface opposite to the fluid guide has an angle in relation to the corresponding swirly fluid for receiving the propelling force from the swirly fluid so as to rotate the electrical generator and thereby generate electrical power. In another embodiment, the swirly fluid sprinkler further has a lighting module for providing illumination while the water spray is discharged.

Swirly fluid sprinkler

An illumination device includes a nozzle, a grip, at least one light element connected to the nozzle, and a moveable turbine generator electrically connected to the light-emitting element. The turbine generator includes at least one rotatable blade. When the turbine generator is moved into the nozzle, the impact of a fluid flowing through the nozzle causes the rotatable blade to rotate, thereby generating electric power to power the light-emitting element. When the turbine generator is moved into the grip, the rotatable blade is not subjected to the impact of the fluid flowing through the nozzle, stopping the turbine generator from generating the electric power.

Illumination devices having movable fluid-driven generator

A generator-driven lighting device for a hand-held power tool has a lighting device, mounted on said main body of said power tool; an electric generator assembly, mounted on said power tool, supplying said lighting device with power; and a transmission device, connecting a generator axis of said generator and a main axis of said power tool, which thereby drives a rotational movement of said generator, causing said generator to generate electric power; wherein by said power tool mechanically driving said generator, said lighting device provides lighting for a user operating said power tool.
