Problems solved by technology

The bonfires lit by ancient ancestors are the earliest lights. The development of modern human civilization is always inseparable from flame and light. Street lights are also guiding the birth and glory of human civilization. In order to overcome the fear and anxiety brought by darkness to human beings , so that street lamps are built in the city to bring light. The current street lamps adopt a fixed design, and the area of ​​illumination is relatively single and fixed, which cannot illuminate every corner of the city.
[0003] Chinese patent (notification number: CN209146927U) discloses a liftable double-headed landscape street lamp, a mounting base, a light pole, a guide sleeve and a lifting assembly; the light pole is set on the mounting base; the lifting assembly is set on the In the light pole; the lifting assembly includes an electric screw and a vertical support; the electric screw is located inside the mounting seat, and the screw of the electric screw extends to the upper end of the light pole; the vertical support is connected to the electric screw It is suitable for following the electric screw to drive the guide sleeve to move up and down along the light pole. Although the device can adjust the height of the street lamp to a certain extent, due to the differentiated lighting of the street lamp, the lighting height at both ends is usually required. Obviously, the above-mentioned street lamps cannot meet these requirements. At the same time, the lifting of the device is to adjust the entire lamp post, and the safety factor is also low. Therefore, further improvement is still needed.

Embodiment 1

[0025] refer to Figure 1~3 , in an embodiment of the present invention, a height-adjustable municipal street lamp includes a fixed base 1, a fixed lamp post 2 is installed in the middle of the upper end of the fixed base 1, and a fixed frame 21 is installed on both sides of the upper end of the fixed lamp post 2, and the fixed frame 21 is additionally One end of the cooling tube 20 is installed, and the bottom of the cooling tube 20 is equipped with a corrugated tube 11. The upper and lower ends of the corrugated tube 11 are respectively sealed with the cooling tube 20 and the lamp housing 8 to prevent external dust and water vapor from entering the inside of the corrugated tube 11. 11 The lamp housing 8 is installed at the bottom, and the circuit board 22 is installed inside the lamp housing 8, and the LED lamp 10 is installed in the middle of the bottom of the circuit board 22. There is a traction steel wire 3, and the end of the traction steel wire 3 is wound on the first ...

Embodiment 2

[0027] In another embodiment of the present invention, the difference between this embodiment and the above embodiment is that a rotating shaft 16 is installed in the middle of the top of the cooling tube 20, and a driving vane 17 is installed at the top of the rotating shaft 16. The rotating shaft 16 is rotated, and the bottom end of the rotating shaft 16 is equipped with cooling vanes 18 for generating airflow inside the cooling tube 20. The top of the cooling tube 20 is provided with a cooling hole 19 for dissipating heat generated by the electrical components inside the cooling tube 20. The heat is exported, and the rotating shaft 16 is fixed on the top of the heat sink 20 through a bearing.

[0028] In the present invention, when the lighting height of the LED lamp needs to be adjusted, the fixed insert handle 7 is loosened, and then the rotating handle 6 is rotated to tighten or tighten the traction steel wire 3, thereby adjusting the height of the LED lamps 10 at both en...

Abstract

The invention relates to the technical field of municipal street lamps, and discloses a height-adjustable municipal street lamp with a fixed base; a fixed lamp post is mounted in the middle of the upper end of the fixed base; fixing frames are mounted on two sides of the upper end of the fixed lamp post; a radiating cylinder is mounted at the other end of the fixing frame; a bellows is mounted atthe bottom end of the radiating cylinder; a lamp shell is mounted at the bottom of the bellows; a movable pulley is connected to the middle of the upper end of the lamp shell; a traction steel wire iswound around the outer side of the movable pulley, a first fixed pulley arranged in the radiating cylinder is wound around the tail end of the traction steel wire, the middle of the traction steel wire sequentially penetrates through a second fixed pulley arranged in the radiating cylinder and a third fixed pulley arranged at the top end of the fixed lamp post, and two rotating shafts are installed at the bottom end in the fixed lamp post. According to the street lamp, through mutual cooperation of the traction steel wire, the movable pulley and the multiple fixed pulleys, the vertical heightof the lamp shell is adjusted, operation is convenient, the safety coefficient is high, labor is saved, and the requirement for illumination of different heights of a main road and an auxiliary roadis met.

Description

technical field [0001] The invention relates to the technical field of municipal street lamps, in particular to a height-adjustable municipal street lamp. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lamps are widely used in various places where lighting is required. Fire is the history of human development. It is a history of entrepreneurship in pursuit of light. The use of fire is an important milestone in the progress of human civilization. The bonfires lit by ancient ancestors are the earliest lights. The development of modern human civilization is always inseparable from flame and light. Street lights are also guiding the birth and glory of human civilization. In order to overcome the fear and anxiety brought by darkness to human beings , so that the establishment of street lamps in the city brings light. At this stage, the...
