Current contact and switching device

The embodiment of the invention provides a current contact and a switching device. The current contact comprises a contact carrier, supports, at least one moving contact, elastic parts and a fixed contact; the contact carrier is provided with at least one limiting mounting hole; the limiting mounting hole runs through the contact carrier. The support passes through the limiting mounting hole and is fixed on the hole side wall of the limiting mounting hole, and the supports extend out of both sides of the limiting mounting hole. At least one moving contact runs through the limiting mounting hole and extends out of both sides of the limiting mounting hole, and the elastic parts are arranged between the supports and the moving contacts, which extend out of the same sides of the limiting mounting hole. The fixed contact is in contact with at least one moving contact of the limiting mounting hole, and the moving contact can roll relative to the fixed contact. According to the current contact and the switching device which are provided by the invention, friction generated when the moving contact and the fixed contact move relatively can be effectively reduced, a counter-acting force of the contact can be effectively inhibited when an inrush current passes through the moving contact, contact discharge ablation caused by instantaneous pop-up of the contact is prevented, and the number of the moving contacts can also be freely regulated as required.

Method for manufacturing sealing device, and sealing device

Provided are: a method for manufacturing a sealing device, the method being configured so that, even if the sealing device has an annular inner peripheral protrusion on the inner peripheral side thereof, the method can increase manufacturing efficiency and enables cutting-off operation with high positional accuracy; and a sealing device which has increased sliding performance and which is less likely to break. A method for manufacturing a sealing device is provided with: a step for forming a cylindrical formed body (100a) consisting of a rubber-like elastic body, the formed body (100a) having circular cylinder surfaces (130) and annular outer peripheral protrusions (110), the circular cylinder surfaces (130) and the annular outer peripheral protrusions (110) being formed and arranged alternately on the outer peripheral side of the formed body (100a), the formed body (100a) also having circular cylinder surfaces and annular inner peripheral protrusions, the circular cylindrical surfaces and the annular inner peripheral protrusions being formed and arranged alternately on the inner peripheral side of the formed body (100a), the circular cylinder surfaces on the outer peripheral side and the circular cylinder surfaces on the inner peripheral side being arranged so as to be located at the same positions in the axial direction, the outer peripheral protrusions and the inner peripheral protrusions being arranged so as to be located at the same positions in the axial direction; and a cutting step for cutting off the formed body (100a) at each of the circular cylinder surfaces (130) on the outer peripheral side.

Elevator equipment

The invention provides novel elevator equipment. The elevator equipment can reduce an influence of unbalance loading, acting on an elevator compartment, of an accompanying cable and inhibits shaking of the accompanying cable by means of a simple structure. One end of the accompanying cable is overhung near the center of the lower end face of the elevator compartment, so the other end of the accompanying cable is fixed to a wall face of a lifting channel in a manner that the accompanying cable extending in the length direction is obliquely located between a range that the accompanying cable is not parallel to the front face of the elevator compartment and not parallel to a side face of the elevator compartment, and then a protective device is disposed on the wall face of the lifting channel in a manner that a planar protective face of the protective device is perpendicular to a bulging direction of the accompanying cable when the elevator compartment moves. A load of the accompanying cable acts near the center of the elevator compartment, so shaking of the elevator compartment can be inhibited, and an interference between a guide rail and the accompanying cable is prevented from occurrence. A reactive force enabling the accompanying cable to shake can also be inhibited from generation between the accompanying cable and the protective device, and the shaking of the accompanying cable is inhibited by means of the simple structure.

Intelligent vibration damping device for over-sea floating wind turbine platform

InactiveCN105020104AVibration reduction target achievedSuppression reaction forceWind motor componentsControl systemFloating platform
The invention discloses an intelligent vibration damping device for an over-sea floating wind turbine platform. The intelligent vibration damping device comprises a control system, turbine actuating systems, self-floating turbine protecting devices and rigid connecting rods, wherein the turbine actuating system are positioned inside the self-floating turbine protecting devices and are rigidly connected with the floating platform by the rigid connecting rods; each turbine actuating system is in signal connection with the control system; the turbine actuating systems, the self-floating turbine protecting devices and the rigid connecting rods are equal in quantity. The control system is used for acquiring and analyzing oscillation signals of the floating platform, sending a control instruction and controlling the turbine actuating system which is required to act to work; a turbine rotates under water to generate a counter-acting force for inhibiting oscillation of the floating platform so as to realize the aim of damping the vibration of the floating platform. The intelligent vibration damping device is simple in structure, rapid in response, applicable to different types of floating platforms, wide in application range and high in practicability.
