The application discloses an elevator braking energy collecting device and relates to the technical field of elevator kinetic energy recovery. The device comprises a braking module installed on the top or bottom of an elevator car; the braking module is in transmission connection with a direct-current generator A arranged on the top or bottom of the elevator car; the end of the direct-current generator A is connected with a CVT gearbox; the braking module comprises a vertically arranged rectangular frame, the opposite two side walls of the rectangular frame are provided with convex columns, the convex columns are rotatably connected with swing arms, the end of the swing arm is rotatably assembled with a mounting shaft through a bearing, the mounting shaft is fitted with a friction roller rolling along the elevator guide rail and a transmission wheel A; a transmission shaft is rotatably arranged between the two convex columns through a bearing, and the transmission shaft is provided with a transmission wheel B in transmission connection with the transmission wheel A. The braking module is arranged on the top and / or bottom of the elevator car to drive the rotation of the direct-current generator A, so that the device can generate electricity in the whole process of the elevator descending.

This invention proposes a self-generating and luminous tire, belonging to tire manufacturing technology. It includes a first power-generating component disposed on the inner wall of the tire tread along the circumferential centerline; a second power-generating component connected to the tire rim via an elastic element and positioned opposite the first power-generating component; and a luminous component connected to both the first and second power-generating components via a circuit. When the tire rotates, the elastic element moves the second power-generating component to a first position in contact with the first power-generating component, and then moves it to a second position away from the first power-generating component. When the second power-generating component is in the first position, the circuit is connected and the luminous component emits light. This invention solves the technical problem of energy consumption that may result from using lighting systems on tires in existing vehicles. It is environmentally friendly while improving nighttime driving safety, enhancing vehicle visibility, and satisfying the public's pursuit of personalization.

The invention relates to the technical field of heat recovery, in particular to a gas heat recovery turbine device which comprises a shell, a gas outlet is formed in the end of the shell, a generator is arranged at the end of the shell, a cleaning plate is arranged in the shell, a cleaning brush is arranged on the surface of the cleaning plate, a circular ring is fixed to the surface of the cleaning plate, and a limiting rod is arranged in the shell. A rotating shaft is arranged in the shell, an air cylinder is arranged in the rotating shaft, a piston rod is arranged at the end of the air cylinder, and the piston rod is connected with the connecting rope; the device has the beneficial effects that an air cylinder drives a piston rod to transversely move, the piston rod moves in a rotating shaft, the piston rod pulls a connecting rope, so that the connecting rope is pulled, the connecting rope pulls a circular ring to move, the circular ring drives a cleaning plate to move, a cleaning brush is arranged on the surface of the cleaning plate, and the cleaning plate moves along a limiting rod; and the cleaning brush is used for cleaning the fins.
