Description

Technical Field

[0001] This utility model relates to the field of street light technology, and in particular to a high-efficiency heat dissipation device for solar street lights. Background Technology

[0002] Currently, most streetlights on the market are solar streetlights. However, existing solar streetlights generally emit a lot of heat during use, which can cause malfunctions, internal overheating, and even fires. This situation can greatly affect the use of solar streetlights. Therefore, we propose a solar streetlight heat dissipation device to solve the above problems.

[0003] Chinese Patent Publication No. CN211976746U discloses a solar street light heat dissipation device, relating to the field of street lights. This solar street light heat dissipation device includes a lampshade, the upper part of which includes a solar panel, and the lower part of the solar panel is fixedly connected to the upper part of the lampshade. Through a control box and the coordinated arrangement of a water inlet, water tank, electrical box, water pump, branch pipe, output pipe, supply pipe, and retaining pipe, the device collects rainwater through the inlet during rainy weather. The water is collected in the water tank, and driven by the electrical box, the water pump outputs power to force water from the output pipe into the supply pipe, thus dissipating heat from the street light. This achieves excellent heat dissipation for the solar street light, solving the problem of poor heat dissipation in existing solar street lights, which can lead to spontaneous combustion.

[0004] However, the solar street light heat dissipation device described in the aforementioned patent document has overly stringent requirements in actual use. It requires rain to collect rainwater for cooling, but due to weather conditions, it cannot be guaranteed that the device can continuously collect rainwater for heat dissipation. The required conditions are quite demanding, and the amount of rainwater collected is not much, which is far from sufficient for the heat dissipation of solar street lights. Utility Model Content

[0005] The main purpose of this utility model is to provide a high-efficiency heat dissipation device for solar street lights, which can effectively solve the problem of harsh operating conditions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency heat dissipation device for solar street lights includes a column, a placement plate fixedly connected to the upper end of the column, a solar panel fixedly connected to the upper end of the placement plate, a cooling component fixedly connected to the lower end of the placement plate, a blowing component fixedly connected to the lower end of the placement plate, a brushing component fixedly connected to the lower end of the placement plate, and an LED light fixedly connected to the lower end of the placement plate.

[0008] Preferably, the cooling component includes a protective box, the upper end of which is fixedly connected to the lower end of the placement plate, a radiator is fixedly connected to the front side wall of the inner cavity of the protective box, and a bevel gear is fixedly connected to the rear end of the radiator.

[0009] Preferably, the transmission assembly includes a fixing plate, the upper end of which is fixedly connected to the lower end of the placement plate, a shaft is rotatably connected to the inner surface of the fixing plate, a bevel gear is fixedly connected to the right end of the shaft, and a pulley is fixedly connected to the left end of the shaft.

[0010] Preferably, the blowing assembly includes a mounting box, the upper end of which is fixedly connected to the lower end of the placement plate. A fan is rotatably connected to the left side wall of the inner cavity of the mounting box. A second pulley is fixedly connected to the left end of the fan. A belt is wound around the outer surfaces of the two second pulleys. A cooling box is fixedly connected to the right end of the mounting box. A heat dissipation pipe is fixedly connected to the right end of the cooling box. A shaft is fixedly connected to the left end of the second pulley.

[0011] Preferably, the second shaft includes a second fixing plate, the left end of the second fixing plate is fixedly connected to the right end of the second shaft, a spring is fixedly connected to the ends of the two second fixing plates away from the center, and a pawl is fixedly connected to the ends of the four springs away from the center.

[0012] Preferably, the brushing assembly includes a fixing plate three, the upper ends of both fixing plates three are fixedly connected to the lower end of the placement plate, the left end of the rear fixing plate three is rotatably connected to a pulley three, the left end of the front fixing plate three is rotatably connected to a pulley four, the outer surfaces of the pulley three and the pulley four are wound together with a belt two, the right end of the pulley four is fixedly connected to a reciprocating screw, the right end of the front fixing plate three is fixedly connected to a guide rod, the outer surface of the reciprocating screw and the outer surface of the guide rod are slidably connected to a brush, and the inner surface of the pulley three is fixedly connected to a ratchet.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can achieve the effect of cooling LED lights by setting cooling components, transmission components and blowing components. Because the cooling box is filled with cold air to cool down when the heat sink rotates and generates low temperature, the cooling effect is better in actual use and the cooling process is more stable. It will not fail to cool down due to weather changes. Furthermore, since it does not involve complex water connections, the cold air heat dissipation system performs better in terms of safety, avoiding safety hazards caused by water leakage, blockage or freezing.

[0015] 2. This utility model, through its designed brushing component, enables the LED light surface to be brushed clean when it becomes dirty, keeping the LED light surface clean. This avoids the problem that the accumulation of dust, dirt, or other debris on the LED light surface can block some light and reduce the lighting effect. Moreover, excessive dust on the LED light surface can affect heat dissipation, causing the LED light temperature to rise. High temperature not only reduces the luminous efficiency of the LED but may also shorten its lifespan. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figure 1As shown, a high-efficiency heat dissipation device for solar street lights includes a column 1, a placement plate 2 fixedly connected to the upper end of the column 1, a solar panel 3 fixedly connected to the upper end of the placement plate 2, a cooling component 4 fixedly connected to the lower end of the placement plate 2, a blowing component 6 fixedly connected to the lower end of the placement plate 2, a brushing component 7 fixedly connected to the lower end of the placement plate 2, and an LED light 8 fixedly connected to the lower end of the placement plate 2.

[0024] When this solution is implemented, while the solar panel 3 supplies the collected electricity to the LED lamp 8 to emit light, the cooling component 4 will also be activated to rotate in the forward direction to cool the inside of the blowing component 6. As the cooling component 4 rotates, it will also drive the blowing component 6 to rotate. Thus, the blowing component 6 blows the cold air inside the blowing component 6 to the surface of the LED lamp 8, thereby achieving the effect of cooling the LED lamp 8.

[0025] When the LED light 8 needs to be cleaned, the operator first actively drives the cooling component 4 to reverse. At this time, the power of the cooling component 4 will pass through the blowing component 6 to the cleaning component 7, so the cleaning component 7 can brush back and forth to clean the surface of the LED light 8, thereby avoiding the problem that the lighting effect of the LED light 8 is not obvious due to too much dirt on the surface.

[0026] Specifically, in order to dissipate heat from streetlights, such as Figure 3 As shown, in this solution, the cooling component 4 includes a protective box 41. The upper end of the protective box 41 is fixedly connected to the lower end of the placement plate 2. A radiator 42 is fixedly connected to the front side wall of the inner cavity of the protective box 41. A bevel gear 43 is fixedly connected to the rear end of the radiator 42.

[0027] For further details, please refer to [link / reference]. Figure 3 The transmission assembly 5 includes a fixed plate 53, the upper end of which is fixedly connected to the lower end of the placement plate 2. A shaft 52 is rotatably connected to the inner surface of the fixed plate 53. A bevel gear 51 is fixedly connected to the right end of the shaft 52, and a pulley 54 is fixedly connected to the left end of the shaft 52.

[0028] For further details, please refer to [link / reference]. Figure 3 The blowing assembly 6 includes a mounting box 61, the upper end of which is fixedly connected to the lower end of the placement plate 2. A fan 63 is rotatably connected to the left side wall of the inner cavity of the mounting box 61. A second pulley 64 is fixedly connected to the left end of the fan 63. A belt 62 is wound around the outer surfaces of the two pulleys 64. A cooling box 65 is fixedly connected to the right end of the mounting box 61. A heat dissipation pipe 66 is fixedly connected to the right end of the cooling box 65. A shaft 67 is fixedly connected to the left end of the second pulley 64.

[0029] When this solution is implemented, while the solar panel 3 supplies the collected electricity to the LED lamp 8 to emit light, the heat sink 42 will also start to rotate forward to cool the surface of the protective box 41, filling the cooling box 65 with cold air. At the same time, the rotation of the heat sink 42 will also drive the bevel gear 1 43, bevel gear 2 51, shaft 1 52, pulley 1 54, mounting box 61, belt 1 62 and pulley 2 64 to rotate, ultimately driving the fan 63 to rotate, blowing the cold air in the cooling box 65 to the heat dissipation pipe 66 and then to the surface of the LED lamp 8, thereby achieving the effect of cooling the LED lamp 8.

[0030] Example 2: Based on Example 1, the surface of LED lamp 8 can be brushed.

[0031] Specifically, in order to clean LED light 8, such as Figure 3 , Figure 4 and Figure 5 As shown, in this scheme, the brushing assembly 7 includes a fixing plate 3 71. The upper ends of both fixing plates 3 71 are fixedly connected to the lower end of the placement plate 2. The left end of the fixing plate 3 71 located at the rear is rotatably connected to a pulley 3 72. The left end of the fixing plate 3 71 located at the front is rotatably connected to a pulley 4 74. The outer surfaces of the pulley 3 72 and the pulley 4 74 are wound together with a belt 2 73. The right end of the pulley 4 74 is fixedly connected to a reciprocating screw 75. The right end of the fixing plate 3 71 located at the front is fixedly connected to a guide rod 76. The outer surfaces of the reciprocating screw 75 and the guide rod 76 are slidably connected to a brush 77. The inner surface of the pulley 3 72 is fixedly connected to a ratchet 78.

[0032] When this solution is implemented, if it is necessary to clean the LED lamp 8, the operator first actively drives the heat sink 42 to reverse. At this time, the power of the heat sink 42 to rotate will pass through the shaft 67 to the pawl 673, thereby causing the ratchet 78 and the pulley 72 to rotate, which in turn drives the belt 73, the pulley 74 and the reciprocating screw 75 to rotate, so that the brush 77 can brush the surface of the LED lamp 8 back and forth on the guide rod 76, thereby avoiding the problem that the lighting effect is not obvious due to too much dirt on the surface of the LED lamp 8.

[0033] The brush 77 hole has a latch that can slide within the groove of the reciprocating lead screw 75.

[0034] In summary, the implementation process of this utility model is as follows:

[0035] When the solar panel 3 supplies the collected electricity to the LED lamp 8 to emit light, the heat sink 42 will also start to rotate forward to cool the surface of the protective box 41 and fill the cooling box 65 with cold air. At the same time, the rotation of the heat sink 42 will also drive the bevel gear 1 43, bevel gear 2 51, shaft 1 52, pulley 1 54, mounting box 61, belt 1 62 and pulley 2 64 to rotate, which will eventually drive the fan 63 to rotate and blow the cold air in the cooling box 65 to the heat dissipation pipe 66 and then to the surface of the LED lamp 8, thereby achieving the effect of cooling the LED lamp 8.

[0036] When the LED lamp 8 needs to be cleaned, the operator first actively drives the heat sink 42 to reverse. At this time, the power of the heat sink 42 rotation will pass through the shaft 67 to the pawl 673, thereby causing the ratchet 78 and the pulley 72 to rotate, which in turn drives the belt 73, the pulley 74 and the reciprocating screw 75 to rotate, so that the brush 77 can brush the surface of the LED lamp 8 back and forth on the guide rod 76, thereby avoiding the problem that the lighting effect of the LED lamp 8 is not obvious due to too much dirt on the surface.

[0037] It should be noted that the specific installation methods, circuit connection methods, and control methods of the heat sink 42, solar panel 3, and LED lamp 8 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
