The invention aims to provide a friction-type electrostatic dust removal keyboard. The friction-type electrostatic dust removal keyboard comprises an upper keyboard cover, a lower keyboard cover, friction cloth and a friction plate, wherein the lower keyboard cover comprises keyboard working elements, key holes and side holes; the keyboard working elements are placed in the lower keyboard cover; the friction cloth fixedly covers the upper surface of the lower keyboard cover; the friction plate is placed on the upper surface of the friction cloth; when the friction-type electrostatic dust removal keyboard is used, the friction plate is inserted into the keyboard through the side holes; the lower surface of the friction plate is in contact with the upper surface of the friction cloth; the overall keyboard is driven to move by reciprocally moving the part, exposed out of the outer ends of the side holes, of the friction plate; the friction plate generates electricity because of the principle of electrification by friction; the dust in gaps of the keyboard is attracted to the friction plate, and then is drawn out of the friction plate through the side holes, so that the dust is brought out, and a dust cleaning effect is achieved.

The invention provides a street lamp photovoltaic panel mounting bracket, and relates to the technical field of photovoltaic panel brackets. The street lamp photovoltaic panel mounting bracket comprises a base and an adjusting mechanism, wherein a street lamp pole is fixedly connected to the surface of the base, the adjusting mechanism is arranged on the surface of the street lamp pole, the adjusting mechanism comprises a first cross rod, the end, which is close to the street lamp pole, of the first transverse rod is fixedly connected with the street lamp pole, the end, which is away from the street lamp pole, of the first transverse rod is rotationally connected with a rotating rod, the end, which is away from the first transverse rod, of the rotating rod is fixedly connected with a first gear, and the end, which is away from the base, of the street lamp pole is fixedly connected with a supporting frame. According to the invention, by arranging the adjusting mechanism, the problems that the angle of a photovoltaic panel is fixed and cannot be adjusted due to the fact that the currently-used street lamp photovoltaic panel brackets are integrally installed on a street lamp pole, the photovoltaic panel is blocked by high-rise buildings or big trees in the face of some special sites, the photovoltaic panel cannot make more comprehensive contact with the sun, and then the electric quantity collection of the street lamp is possibly insufficient are solvced.

The invention discloses a cable dirt cleaning device. The cable dirt cleaning device comprises a box body, a power mechanism, a travelling mechanism, a clamping device, and a cleaning mechanism, wherein a sliding plate capable of sliding up and down is arranged on the box body; a wire inlet is formed in the box body; the power mechanism comprises a driving device and a first transmission shaft; the driving device is fixed on the sliding plate; a driving part of the driving device is connected with the first transmission shaft through a bevel gear set to drive the first transmission shaft to rotate; the travelling mechanism comprises a second transmission shaft and a third transmission shaft which are arranged on the sliding plate as well as a driven shaft arranged on the box body; the clamping mechanism comprises a hand wheel; the hand wheel is arranged outside the box body and connected with the sliding plate in a threaded manner; the hand wheel is screwed on the outer wall of the box body in the threaded manner to clamp the sliding wheel; the cleaning mechanism comprises a copper brush capable of sleeving the cable; the copper brush is connected with the box body. The cable dirt cleaning device can directly drive the copper brush on the cable to clean the dirt through the travelling mechanism and to achieve high efficiency.
