The invention provides a centrifugal fan lamp device and an air blowing method thereof. The centrifugal fan lamp device is formed by hiding a centrifugal fan in a lamp device. Two fan blades opposite in directions are arranged on the centrifugal fan driven by a motor, a first flow passage and a second flow passage which are matched with the centrifugal fan are arranged in the lamp device, and the second flow passage converges into the first flow passage. The shape of one of the fan blades of the centrifugal fan inclines forwards, therefore, the lamp device can sucks air form the center of the position right below the lamp device, plenty of air is blown out from the periphery of the center of the position right below the lamp device, the lamp device is provided with a narrow air outlet, then large lift is obtained, and a certain amount of air flow can be maintained.

The invention discloses a floating type automobile panoramic sunroof assembling manipulator, and relates to the technical field of automobile manufacturing. The floating type automobile panoramic sunroof assembling manipulator comprises a floating frame connected with a main bearing beam, wherein shared and switchable supporting blocks are mounted on the two sides of the floating frame; a floatingdevice and a floating lock are arranged in the middle of the floating frame; a first air cylinder and a second air cylinder are mounted on the floating frame and positioned on the two sides of the floating device side by side, a positioning pin is mounted on the first air cylinder, and a switchable height supporting block is mounted on the second air cylinder; an external three-axis translation mechanism connecting seat is arranged on the main bearing beam, a mounting connecting plate is arranged at the end, connected with the floating frame, of the main bearing beam, and a handle provided with an operation box is arranged at the other end of the main bearing beam; and handrails and buttons are further arranged on the two sides of the floating frame. According to the floating type automobile panoramic sunroof assembling manipulator, the problems that an existing automobile panoramic sunroof assembling manipulator has no positioning function, the mounting precision cannot be guaranteed, the bad defects such as wind noise and water leakage are prone to being caused, and adjustment is not facilitated when the position of a diagonal mounting hole of a panoramic sunroof deviates can besolved.

The invention discloses an automobile rearview mirror cleaning system and method, and relates to the field of automobile accessories. The automobile rearview mirror cleaning system comprises an air pump fixedly arranged in an automobile body, at least one air nozzle fixedly mounted on one side of a rearview mirror, and an air pipe fixedly arranged between the air pump and the air nozzle; orientation of the air nozzle is parallel to a mirror surface of the rearview mirror; and the air nozzle sprays an air flow parallel to the mirror surface of the rearview mirror. In the invention, an air barrier can be formed outside the mirror surface of the rearview mirror to prevent rainwater from adhering to the mirror surface of the rearview mirror; when rainwater passes through the air barrier, waterdrops on the mirror surface of the rearview mirror can be quickly blown off by an high-speed airflow; an evaporation speed of rainwater on the mirror surface of the rearview mirror can be increased by utilizing a high-speed airflow; and the air nozzle is fixedly installed on one side of the inner portion of the rearview mirror, a contact area with air is reduced, meanwhile, the air nozzle can befully fixed, a problem of a wind noise is avoided, the air pump and the air nozzle are physical products, and using time is far longer than that of a rainproof spraying agent.

A low-noise conducting wire of the invention relates to a special conducting wire used by the overhead transmission line, and the invention is especially suitable for the improving of the new-built extra-high voltage overhead transmission line and the overhead transmission. The structure comprises a bearing core and a conductor. The exterior of the bearing core is arranged with a plurality of layers of conductor. The conductor next to the bearing core is a single wire with a circular cross-section. The outmost layer conductor is a single wire with an odd-shaped cross-section. The outmost layer conductor is provided with single wire of partial odd-shaped cross-sections higher than the single wire of other odd-shaped cross-sections. A projection which is provided with an opening angle is formed on the surface of the conducting wire. The height of the projection formed on the surface of the conducting wire is 2.3-2.7mm, and the opening angle is 30-120degrees. The height of the special-shaped wire fold of the projection at the exterior layer of the low-noise conducting wire is less than the diameter of the current disturbing wire. The artificial operation for winding the current disturbing wire is saved. The invention has the advantages of light weight, convenient construction, reducing the corona sound of the conducting wire and the radio interference level, and effectively preventing the wind noise of the conducting wire.
