Description

Rotation device of pole system{ROTATION DEVICE FOR POLE SYSTEM}

The present invention relates to a rotating device of a pole system, and more particularly, to a rotating device of a pole system that is installed on the pole to generate and transmit rotational force.

In general, CCTV cameras and lighting facilities are installed on roadsides or residential alleys to collect various information by monitoring the traffic of vehicles or pedestrians, or to prevent crime. CCTV cameras are installed downward at a predetermined angle at the high point of the power pole to shoot a specific area.

Due to the nature of CCTV cameras and lights installed in high places, when used for a long time, dust accumulates or functions deteriorate due to external environmental changes such as wind. In addition, if you want to repair or clean CCTV cameras or lights, you have to rent and use expensive equipment such as high place ladders, cargo cranes, etc., so maintenance costs are high and traffic may be disturbed as the equipment occupies the roadway. have.

For CCTV cameras and lighting equipment, when a pedestrian, etc. approaches the CCTV camera's monitoring area at night, the pedestrian is detected by the detection sensor installed in the CCTV camera, and the light is automatically turned on and the CCTV camera operates to take pictures of the subject. Perform.

CCTV cameras and lighting equipment basically receive power from a storage battery or a commercial power grid, and emergency power is generally supplied from a solar panel installed on the top of a power pole. In this regard, Patent Document 1 discloses a solar street light having a CCTV, characterized in that when replacing the battery, a surplus battery is selected and replaced with a new battery immediately to maintain good CCTV operation.

Existing CCTV cameras and lighting equipment with solar panels have a disadvantage of low solar power generation efficiency because they are usually fixedly installed with solar panels. Although a system for moving a solar panel by tracking the movement of the sun for solar power generation has been disclosed, there is a problem that it is difficult to apply to CCTV cameras and lighting equipment because the device is complex and expensive.

In order to increase solar power generation efficiency, it is preferable to rotate the solar panel along a predetermined path in consideration of the amount of sunlight. However, if the solar panel is placed on the top of the pole and the rotation axis of the driving motor is simply connected to the solar panel and rotated, an overload may be applied to the rotation axis of the driving motor, and when an external force such as wind is applied, the rotation axis and the solar panel A countermeasure is required because a problem of twisting or damage occurs at the connection part of the connector.

The rotating device 100 provides the rotational force of the drive motor 107 to the gear unit 105 to rotate the first tubular body 101, thereby fixing a rotation target fixed to the support plate 101a of the first tubular body 101. The chain solar panel 15a is rotated. The first tubular body 101 rotates with respect to the second tubular body 106 fixed to the pole while stably supporting the solar panel 15a. Since the bearing 102 is interposed between the first tubular body 101 and the second tubular body 106, structurally stable and smooth rotation can be achieved.

The solar panel 15a of the solar module 15 may be rotated in one direction at a preset time and speed by the rotating device 100 of the pole system to increase the amount of solar power generation.

The rotating device 100 of the pole system according to the present invention is shaken by the rotating object connected to the pole 10 using the first tubular body 101 and the second tubular body 106 assembled with the bearing 102 interposed therebetween. Without it, it can stably transmit rotational force. During operation of the driving motor 107, the rotational force is transmitted to the bearing 102 through the gear part 105 to rotate the upper ring 102a of the bearing 102, and at the same time, the rotational force connected to the upper ring 102a. 1 By rotating the tubular body 101, the object to be rotated slowly rotates. The first tubular body 101 rotates with respect to the second tubular body 106 fixed to the pole while stably supporting the rotating object.

The gear part 105 is engaged with the gear teeth formed along the circumference of the upper ring 102a of the bearing 102 to transmit rotational force, and the upper ring 102a is connected to the first tubular body 101 to be connected to the first tubular body ( 101) and rotates integrally. The first tubular body 101 rotates integrally with the rotation object fixed to the support plate 101a. At this time, since at least a part of the gear unit 105 is disposed to be inserted into the hollow of the bearing 102, space utilization efficiency can be maximized.

Therefore, when the present invention is applied, the solar panel 15a installed on the top of the pole can be stably rotated to perform the solar power generation with high efficiency.

The assembly in which the assembly of the first tubular body 101 and the second tubular body 106 is coupled to the solar panel 15a is compared with the diameter of the rotating shaft of the driving motor, the first tubular body 101 and the second tubular body ( Since the diameter of 106) is remarkably large, the rotational force can be stably transmitted compared to the existing technology, which simply connects the rotating shaft of the drive motor to the solar panel to rotate. That is, even when external force such as vibration or wind generated from the driving motor is applied, the rotational force of the driving motor can be transmitted to the solar panel 15a without error.

In addition, rotation can be made smoothly by the bearing 102, and when the circular path in which the solar panel 15a rotates is subdivided into the second hand of the needle watch, there is a remarkable effect that precise rotation control is possible in seconds. .
