Description

Technical Field

[0001] The utility model relates to the technical field of street lamps, in particular to an energy-saving lighting street lamp. Background Art

[0002] Street lights are an important part of public facilities. At present, the power supply of existing street lights mainly uses municipal electricity. Although it can achieve the purpose of lighting, it consumes a lot of municipal electricity, and the wiring and installation workload is large, the investment cost is high, and the maintenance is cumbersome and cannot be moved. In addition, in some areas where municipal electricity cannot be covered, street lights cannot be used for lighting due to lack of electricity, which brings many inconveniences to pedestrians. With the development of science and technology, solar street lights have emerged. Existing solar street lights usually add solar panels to street lights, and combine controllers, batteries and other equipment to effectively ensure the normal power supply of street lights at night.

[0003] In semi-arid or highly polluted areas, there are many pollutants and dust particles in the air, which will cover the surface of the solar panels. These dust will absorb part of the sunlight that normally shines on the solar panels, thus affecting the solar panels' efficiency in absorbing sunlight. Therefore, workers are required to clean the solar panels. However, since the solar panels are installed high up on the light poles, workers need to climb the light poles to clean them, which is not only cumbersome but also has certain safety risks.

The pulling handle 18 is pulled downward, thereby driving the transmission rod 16 downward. During the downward movement of the transmission rod 16, the pull rope 6 is driven downward, thereby pulling the slide bar 4 to slide. At the same time, the transmission rod 16 drives the protective shell 14 to slide away from the lamp pole 1 under the transmission action of the transmission assembly. When the pulling handle moves to the lower end of the first through hole 17, the protective shell 14 protects the lighting device. Then, the locking assembly is adjusted so that the locking assembly limits the position of the pulling handle 18, thereby maintaining the protective state of the protective shell 14 for the lighting device.

The transmission rod slides with the lamp pole along the length direction of the lamp pole, and the top of the transmission rod is connected to the end of the pull rope away from the sliding rod. The outer wall of the lamp pole is provided with a first through hole connected to the inside of the lamp pole. The first through hole is strip-shaped, and its length direction is consistent with the length direction of the lamp pole. The transmission rod is provided with a pulling handle, which extends horizontally outward away from one end of the transmission rod and passes through the first through hole.

4. The energy-saving lighting street lamp according to claim 3, characterized in that: A transmission assembly is provided between the transmission rod and the protective shell. By pulling the transmission rod, the protective shell will be driven to slide under the transmission action of the transmission assembly. A locking assembly for limiting the position of the pulling handle is provided on the lamp pole. The position of the pulling handle is limited by the locking assembly to maintain the position of the protective shell.

5. The energy-saving street lamp according to claim 4, characterized in that: The locking assembly includes an arc block, which is formed by the outer wall of the lamp pole extending horizontally outward, and is a hollow structure with two ends open. An arc locking block is arranged inside the arc block, and the arc locking block can slide along the inner wall of the arc block and can slide out of the opening of the arc block; A second through hole connected to the inside of the arc block is provided on the top of the arc block, and a pushing handle is provided on the arc locking block. The pushing handle extends upward from one end of the arc locking block and passes through the second through hole. The arc locking block can be pushed out of the opening of the arc block by pushing the pushing handle. When the arc locking block slides out of the opening of the arc block and abuts against the upper side of the pulling handle, the position of the pulling handle is limited.

6. The energy-saving lighting street lamp according to claim 4, characterized in that: The transmission assembly includes a first rack provided on the transmission rod, the first rack extending along the length direction of the transmission rod, a second rack provided on the mounting rod and slidingly matched with the second rack, the second rack extending along the length direction of the mounting rod, and the second rack being connected to the protective shell at one end away from the lamp pole; A transmission gear set is arranged between the first rack and the second rack, and the first rack is connected by the transmission gear set. By pulling the transmission rod, the first rack will be driven to move synchronously. Under the transmission action of the transmission gear set, the first rack will push the second rack to slide on the mounting rod, thereby driving the protective shell to move.

7. An energy-saving street lamp according to any one of claims 3 to 6, characterized in that: A cleaning strip is arranged in the protective shell. The side of the cleaning strip away from the protective shell abuts against the lighting surface of the lighting fixture. The movement of the protective shell synchronously drives the cleaning strip to move. The cleaning strip cleans the lighting surface of the lighting fixture during the movement.

8. The energy-saving street lamp according to claim 7, characterized in that: A first pulley for supporting a pull rope is arranged inside the lamp pole, and the first pulley is located at the top of the lamp pole. The pull rope is wound around the wheel surface of the first pulley at one end away from the slide rod, and then extends vertically downward and is connected to the transmission rod.
