Abstract

The invention relates to a streetlamp rotator, which takes generator rotor excitation theory as technical basis. In the streetlamp rotator, a slowly rotating micromotor is arranged on a level board of a fixed pipe, a rotating shaft of the motor is connected with an insulative rotor, a rotating pipe and the prior lamp assembly into a whole, and when the motor rotates, the insulative rotor, the rotating pipe and the prior lamp assembly rotate synchronously. The insulative rotor is provided with positive and negative collecting rings the outsides of which are electrically contacted with corresponding electric brushes in a sliding mode; the electric brushes are connected with fixed power sources; and the insides of the collecting rings are welded with copper wires respectively, welding spots correspond to wire chases of the insulative rotor, and the wires pass through wire holes of the rotating pipe along the wire chases to be connected with the prior lamp assembly. The streetlamp rotator is arranged on the upper part of the prior light pole and connected by a flange, the prior streetlamp assembly is connected with an upper mounting hole of the rotator, and the on, off, rotation and stoppage of the street lamp are controlled by a light controller or a streetlamp control center; therefore, a rotating streetlamp is formed, and increases new aesthetic feeling for urban night scenes.

Description

Street lamp rotating device

Affiliated technical field

The invention belongs to public street lighting field, city

Background technology

Existing street lamp assembly (tens light fixtures of assembling on the light pole) does not rotate illumination functions, and the street night scene lacks new scenery.The present invention has designed street lamp rotating device with reference to electrotechnics generator amature excitation principle, the street lamp that does not rotate is over the years increased rotate illumination functions, increases a kind of new impression to urban landscape.

Summary of the invention

The present invention solves the technical scheme that existing street lamp can not rotate: with generator amature excitation theory is technical basis, fixing AC power is changed into the rotation power supply by the combination of street lamp rotating device parts with fixed power source, the annexation of its parts is: in fixing body with a micromotor (motor outline line in accompanying drawing 1, its internal structure is omitted) be installed on the level board of fixing body, motor shaft passes level board and is connected with insulative rotor with pin, and the insulative rotor square shaft is connected with rotation body square hole.The collector ring of two mutually insulateds is installed on insulative rotor, slides with corresponding brush respectively and electrically contacts in the outside of collector ring, and brush is connected with fixed power source with electric wire, and the pressure of brush on insulative rotor leans on the spring adjusting in the brush carrier.The inboard of the collector ring insulated copper wire of burn-oning respectively, the wire casing on the corresponding insulative rotor of solder joint, electric wire passes the line hole of rotating body along wire casing and is electrically connected with light fixture, after power on circuitry, the motor drives insulative rotor is rotated body, rotates the illumination of power supply and light fixture co-rotation.

It is characterized in that: utilize the slip of positive and negative collector ring on positive and negative brush on the fixing body and the insulative rotor to electrically contact, fixed power source is changed into rotatable power supply, make the motionless street lamp of tradition realize rotating and throw light on.

The invention has the beneficial effects as follows: this rot is existing different modeling, and a street lamp that illumination is not rotated is changed into the street lamp of rotation, increases a kind of new viewpoint for the avenue night scene.
