Description

Technical Field

[0001] The utility model relates to the technical field of solar street lamps, and more specifically to a heat dissipation type waterproof solar street lamp. Background Art

[0002] Solar street lights are lighting equipment that use solar energy to generate electricity and store electrical energy. They have the advantages of being environmentally friendly, energy-saving, and requiring no wiring.

[0003] The prior art discloses a utility model patent named "a heat dissipation waterproof solar street light" with application number CN202122924217.X. The entire lighting assembly is installed under the support plate to prevent it from being attacked by rainwater. A fixed net is installed on the outside of the lighting lamp to dissipate heat. In the hot summer, the lighting lamp will generate a lot of heat due to the influence of temperature. As long as the small motor is started and the small motor drives the gear to rotate, the gear will drive the rack below it to move, and the rack will slide in the slide groove at the bottom of the heat dissipation cover to limit it. The fan installed under the fan connecting plate can realize horizontal movement to dissipate heat for the lighting lamp.

[0004] Although the fan directly blows the light to increase the heat dissipation effect of the light, the water vapor and impurities in the air will pass through the fixed net to affect the light.

[0005] A utility model patent named "a heat dissipation waterproof solar street lamp" with application number CN201922050422.0 is also disclosed. The utility model patent is installed with a fan and air vents to dissipate the heat of the lamp body by the fan, and at the same time, the air vents are used to dissipate the heat inside the shell to the outside, so as to prevent the temperature inside the shell from being too high and thus burning the lamp body. The air vents are opened to increase the heat dissipation effect, but the air vents, while serving as a heat channel, also provide a channel for external impurities, although the impurities in the air are filtered through the positive generator and the negative generator;

[0006] However, in order to prevent impurities and water vapor from the outside air from entering the interior, the positive generator and the negative generator need to be kept powered on even during the day when the street lights do not need to be turned on, which increases the energy consumption and causes energy waste.

A plurality of evenly arranged heat conducting plates 11 are connected, one end of the heat conducting plate 11 passes through the lampshade 3 to the inside thereof, and the heat conducting plate 11 clamps the inner impeller 8 and the outer impeller 9 in the middle; the lampshade 3 is protected by the fixing plate 2 to prevent direct rain, and the lampshade 3 prevents water vapor and impurities from entering the inside to affect the lighting lamp 6. When the temperature inside the lampshade 3 is too high due to the lighting lamp 6 being turned on, the hot air flow in the lampshade 3 is stirred by the inner impeller 8, so that the heat is more evenly contacted and transferred to the heat conducting plate 11, and then the outer impeller 9 stirs the external air to exchange heat with the heat conducting plate 11, thereby achieving uniform heat dissipation inside the lampshade 3, and during this process, the inside of the lampshade 3 is not connected to the outside world, while ensuring the heat dissipation of the lighting lamp 6 inside the lampshade 3, the waterproof effect of the lampshade 3 on the lighting lamp 6 is guaranteed.

[0025] Furthermore, the outer wall of the lampshade 3 is fixedly connected with an air collecting hood 12, and the air collecting hood 12 sets the heat conductive sheet 11 and the outer impeller 9 therein, and the ends of the air collecting hood 12 are provided with a plurality of air inlet grooves 13 connected with the interior thereof, and the outer wall of the air collecting hood 12 is provided with exhaust grooves 14 connected with the interior thereof, and the center of the exhaust grooves 14 is the same as the center of the linkage rod 7, and the motor 10 is fixedly connected with the bottom of the air collecting hood 12; the heat conductive sheet 11 is set inside by the air collecting hood 12, and when the outer impeller 9 rotates, the gas in the air collecting hood 12 carrying the heat of the heat conductive sheet 11 is discharged from the exhaust grooves 14, and at this time, due to the pressure change in the air collecting hood 12, the external gas will enter the air collecting hood 12 from the air inlet grooves 13, and after contacting with the heat conductive sheet 11 to absorb heat, it will be discharged from the exhaust grooves 14, so as to circulate, thereby increasing the heat exchange effect of the external gas on the heat conductive sheet 11, and increasing the heat dissipation effect on the lighting lamp 6 inside the lampshade 3.

By providing the flow holes 15 , when the inner impeller 8 and the outer impeller 9 rotate, the gas can flow through the flow holes 15 , thereby increasing the contact heat exchange effect between the gas and the heat conducting plate 11 .

[0030] Working principle: This embodiment provides a heat dissipation waterproof solar street light. When in use, the column 1 is inserted into the road surface and fixed, and the fixing plate 2 is protected by the lampshade 3 to prevent rain from directly falling, and the lampshade 3 prevents water vapor and impurities from entering the interior to affect the lighting lamp 6. The solar energy is converted into electrical energy by the solar panel 4 and stored in the battery 5. The battery 5 provides electrical energy for the lighting lamp 6, so that the lighting lamp 6 lights up;

[0031] When the temperature inside the lampshade 3 is too high due to the lighting lamp 6 being turned on, the motor 10 drives the linkage rod 7 to rotate, and the linkage rod 7 rotates synchronously to drive the inner impeller 8 and the outer impeller 9 to rotate, so that the hot air flow inside the lampshade 3 is stirred by the inner impeller 8, so that the heat is more evenly contacted and transferred to the heat conducting plate 11, and then the outer impeller 9 stirs the external air to exchange heat with the heat conducting plate 11, so as to achieve uniform heat dissipation inside the lampshade 3, and the inside of the lampshade 3 is not connected to the outside during this process, while ensuring the heat dissipation of the lighting lamp 6 inside the lampshade 3, the waterproof effect of the lampshade 3 on the lighting lamp 6 is guaranteed;

[0032] The heat conducting sheet 11 is covered inside the air collecting hood 12, and when the outer impeller 9 rotates, the gas in the air collecting hood 12 carrying the heat of the heat conducting sheet 11 is discharged from the exhaust groove 14. At this time, due to the pressure change in the air collecting hood 12, the external gas will enter the air collecting hood 12 from the air inlet groove 13, and will contact with the heat conducting sheet 11 to absorb heat, and then be discharged from the exhaust groove 14.
