Description

Technical Field

[0001] This utility model relates to the field of street light technology, specifically a heat dissipation structure for a solar street light. Background Technology

[0002] With the increasing global emphasis on clean energy and sustainable development, solar energy, as an inexhaustible and renewable energy source, has been widely used in the lighting field, with solar streetlights being a prime example. Solar streetlights use solar panels as their primary energy source, converting solar energy into electricity through the photovoltaic effect and storing it in batteries to power the streetlights.

[0003] A search revealed a utility model patent with Chinese patent publication number CN212157000U, which discloses a heat dissipation structure for a solar street light, including a light pole, a bracket, a lighting lamp, and a solar panel. The bracket is installed on the top of one side wall of the light pole, and the lighting lamp is installed at one end of the bracket. The solar panel is installed at the top of the light pole, and a heat dissipation mechanism is installed on the top surface of the lighting lamp. The heat dissipation mechanism consists of a protective cover, a copper plate, a slot, a semiconductor cooling chip, a first heat dissipation fin, a crossbar, a fan, a temperature sensor, a microcontroller, an exhaust pipe, and a dustproof net.

[0004] The aforementioned device cools the lamps using electrical appliances such as semiconductor cooling chips and fans. However, these electrical appliances consume a lot of energy during operation, which inevitably leads to a decrease in light intensity during subsequent use, leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for a solar street light to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for a solar street light, comprising a lamp post, a lighting lamp fixedly mounted on the top of the lamp post via a bracket, a heat dissipation assembly mounted on the top of the lighting lamp, the heat dissipation assembly comprising a plurality of equally spaced heat dissipation pipes, all of which are located on the top of the lighting lamp, a common water inlet pipe fixedly connected to one end of the top of each of the heat dissipation pipes, and a common water outlet pipe fixedly connected to one end of the bottom of each of the heat dissipation pipes, a corner bracket 1 fixedly connected to the outer walls of both ends of the lighting lamp, a corner bracket 2 fixedly mounted on the top of each of the two corner bracket 1s, and the two corner bracket 2s respectively fixedly connected to two heat dissipation pipes, and a basic heat dissipation component provided on the top of the lighting lamp, the basic heat dissipation component comprising heat dissipation fins.

[0007] As a further preferred embodiment of this technical solution, the heat dissipation fins are disposed between the lighting lamp and several heat dissipation pipes, and several fins on the top of the heat dissipation fins are slidably inserted into the gaps between several heat dissipation pipes.

[0008] It can cool down the lighting lamp during daily use and can also cool it down quickly when needed, which helps to prevent the lighting lamp from being shortened in life due to overheating. When the temperature sensor inside the lighting lamp detects that the temperature is higher than the threshold, the microcontroller inside the lamp post controls the solenoid valve to open. The water in the water tank is at a high level and will flow into the water inlet pipe under the action of gravity. Then, it will enter several heat dissipation pipes through the water inlet pipe and finally be discharged out through the water outlet pipe. When the water flows through the heat dissipation pipes, the heat inside the lighting lamp will be quickly carried away. In addition, the large contact area between the heat dissipation fins and the outside can further improve the heat dissipation effect. When the temperature sensor detects that the temperature is lower than the threshold, the microcontroller controls the solenoid valve to close, so that the lighting lamp can always maintain a relatively stable temperature.

[0009] As a further preferred embodiment of this technical solution, a water supply assembly is installed at the top of the lamp post. The water supply assembly is located at the top of the lighting lamp and includes a support frame fixedly installed on the top of the outer wall of the lamp post. A water collection tank is fixedly installed on the top outer wall of the support frame. A solenoid valve is fixedly installed on the bottom of one side of the outer wall of the water collection tank. The outlet of the solenoid valve is connected to the inlet pipe. A first one-way valve is fixedly installed on the top of the water collection tank, and a collection hopper is fixedly installed at the inlet of the one-way valve. A filter screen is fixedly installed inside the collection hopper. A reinforcing plate is fixedly installed on the outside of the support frame by bolts, and the reinforcing plate covers the outside of the lamp post.

[0010] When it rains, the rainwater falls onto the top of the filter screen, where debris is trapped. The water then passes through the filter holes into the collection hopper and is finally collected in the water tank for temporary storage, which helps to save water resources for later use.

[0011] As a further preferred embodiment of this technical solution, a second one-way valve is fixedly installed on the outer wall of one side of the collection hopper, and a water supply pipe is fixedly installed on the second one-way valve. The water supply pipe is connected to an external tap water pipe, and a level gauge is fixedly installed on the outer wall of the top of the water collection tank.

[0012] As a further preferred embodiment of this technical solution, two support rods are fixedly connected to the bottom outer wall of the support frame, and one bottom end of each of the two support rods is fixedly connected to the outer circumference of the lamp post.

[0013] As a further preferred embodiment of this technical solution, a solar panel is fixedly installed at the top of the lamp post via a bracket.

[0014] As a further preferred embodiment of this technical solution, the water collection tank and the collection hopper are both covered with heat-insulating cloth, and heat-insulating cotton is filled between the heat-insulating cloth and the water collection tank and the collection hopper.

[0015] This utility model provides a heat dissipation structure for a solar street light, which has the following beneficial effects:

[0016] (1) By setting up a heat dissipation component, this utility model can cool down the lighting lamp during daily use and can also cool it down quickly when needed, which helps to avoid the lighting lamp from being affected by excessive temperature. When the temperature sensor inside the lighting lamp detects that the temperature is higher than the threshold, the microcontroller inside the lamp post controls the solenoid valve to open. The water in the water collection tank is at a high level and will flow into the water inlet pipe by gravity. Then, it will enter several heat dissipation pipes through the water inlet pipe and finally be discharged out through the water outlet pipe. When the water flows through the heat dissipation pipe, the heat inside the lighting lamp will be quickly carried away. In addition, the heat dissipation fins have a large contact area with the outside, which can further improve the heat dissipation effect. When the temperature sensor detects that the temperature is lower than the threshold, the microcontroller controls the solenoid valve to close, so that the lighting lamp can always maintain a relatively stable temperature.

[0017] (2) By setting up a water supply component, when it rains, the rainwater will fall onto the top of the filter screen, and the debris will be intercepted. The water will pass through the filter holes into the collection bucket and finally be collected in the water collection tank for temporary storage, so as to facilitate later use and save water resources.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, a heat dissipation structure for a solar street light includes a lamp post 1. A lighting lamp 3 is fixedly installed at the top of the lamp post 1 via a bracket. A heat dissipation component 5 is installed on the top of the lighting lamp 3. The heat dissipation component 5 includes several heat dissipation pipes 503 distributed at equal intervals. The several heat dissipation pipes 503 are all located on the top of the lighting lamp 3. One end of the top of the several heat dissipation pipes 503 is fixedly connected to the same water inlet pipe 504, and one end of the bottom of the several heat dissipation pipes 503 is fixedly connected to the same water outlet pipe 505. An angle bracket 1 501 is fixedly connected to the outer wall of both ends of the lighting lamp 3. An angle bracket 2 502 is fixedly installed on the top of each of the two angle brackets 1 501. The two angle brackets 2 502 are respectively fixedly connected to two heat dissipation pipes 503. A basic heat dissipation component is provided on the top of the lighting lamp 3. The basic heat dissipation component includes heat dissipation fins 506.

[0025] The heat dissipation fins 506 are disposed between the lighting lamp 3 and several heat dissipation pipes 503, and several fins on the top of the heat dissipation fins 506 are slidably inserted into the gaps between several heat dissipation pipes 503.

[0026] When the temperature sensor (preferably DS18B20) inside the lighting lamp 3 detects that the temperature is higher than the threshold, the microcontroller (preferably Arduino or STM32) inside the lamp post 1 controls the solenoid valve 605 to open. The water in the water collection tank 602 is at a high level and will flow into the inlet pipe 504 under the action of gravity. Then, it will enter several heat dissipation pipes 503 through the inlet pipe 504 and finally be discharged out through the outlet pipe 505. When the water flows through the heat dissipation pipes 503, the heat inside the lighting lamp 3 will be quickly carried away. In addition, the heat dissipation fins 506 have a large contact area with the outside, which can further improve the heat dissipation effect. When the temperature sensor detects that the temperature is lower than the threshold, the microcontroller controls the solenoid valve 605 to close, so that the lighting lamp 3 can always maintain a relatively stable temperature.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, a water supply component 6 is installed on the top of the lamp post 1. The water supply component 6 is located at the top of the lighting lamp 3. The water supply component 6 includes a support frame 601 fixedly installed on the top of the outer wall of the lamp post 1. A water collection tank 602 is fixedly installed on the top outer wall of the support frame 601. A solenoid valve 605 is fixedly installed on the bottom of one side outer wall of the water collection tank 602. The outlet of the solenoid valve 605 is connected to the inlet pipe 504. A first one-way valve is fixedly installed on the top of the water collection tank 602. A collection hopper 603 is fixedly installed at the inlet of the one-way valve. A filter screen 604 is fixedly installed inside the collection hopper 603. A reinforcing plate 606 is fixedly installed on the outside of the support frame 601 by bolts. The reinforcing plate 606 covers the outside of the lamp post 1.

[0028] A second one-way valve is fixedly installed on one side of the outer wall of the collection hopper 603, and a water supply pipe 608 is fixedly installed on the second one-way valve. The water supply pipe 608 is connected to an external tap water pipe. A level gauge 607 is fixedly installed on the top outer wall of the water collection tank 602.

[0029] When it rains, rainwater falls onto the top of the filter screen 604, where debris is trapped. The water then passes through the filter holes into the collection hopper 603 and is finally collected in the water collection tank 602 for temporary storage, which helps to save water resources. When the level gauge 607 detects that the water level in the water collection tank 602 is below the threshold, the microcontroller will control the external tap water supply valve, and tap water can directly enter the water collection tank 602 through the water supply pipe 608. When the level gauge 607 detects that the water level has reached half position, it sends a signal again. When the microcontroller receives the signal, it controls the external water supply valve to close.

[0030] like Figure 1 and Figure 2 As shown, two support rods 4 are fixedly connected to the bottom outer wall of the support frame 601. One end of each support rod 4 is fixedly connected to the outer circumference of the lamp post 1, which can disperse the stress borne by the support frame 601 and improve the stability of the water collection tank 602.

[0031] like Figure 1 and Figure 2 As shown, a solar panel 2 is fixedly installed at the top of the lamp post 1 via a bracket.

[0032] like Figure 1 and Figure 2 As shown, both the water collection tank 602 and the collection hopper 603 are covered with heat-insulating cloth, and heat-insulating cotton is filled between the heat-insulating cloth and the water collection tank 602 and the collection hopper 603, which can prevent the external temperature from affecting the temperature of the water inside the water collection tank 602 too much.

[0033] This utility model provides a heat dissipation structure for a solar street light, and its specific working principle is as follows:

[0034] When the device is working, the heat dissipation fins 506 on the outside of the lighting lamp 3 can conduct the heat dissipated during operation, which can meet the daily heat dissipation needs of the lighting lamp 3. When the temperature sensor inside the lighting lamp 3 detects that the temperature is higher than the threshold, the microcontroller inside the lamp post 1 controls the solenoid valve 605 to open. The water in the water collection tank 602 is at a high level and will flow into the water inlet pipe 504 by gravity. Then, it will enter several heat dissipation pipes 503 through the water inlet pipe 504 and finally be discharged out through the water outlet pipe 505. When the water flows through the heat dissipation pipes 503, the heat inside the lighting lamp 3 will be quickly carried away. In addition, the heat dissipation fins 506 have a large contact area with the outside, which can further improve the heat dissipation effect. When the temperature sensor detects that the temperature is lower than the threshold, the microcontroller controls the solenoid valve 605 to close, so that the lighting lamp 3 can always maintain a relatively stable temperature.

[0035] When it rains, rainwater falls onto the top of the filter screen 604, where debris is trapped. The water then passes through the filter holes into the collection hopper 603 and is finally collected in the water collection tank 602 for temporary storage, which helps to save water resources. When the level gauge 607 detects that the water level in the water collection tank 602 is below the threshold, the microcontroller will control the external tap water supply valve, and tap water can directly enter the water collection tank 602 through the water supply pipe 608. When the level gauge 607 detects that the water level has reached half position, it sends a signal again. When the microcontroller receives the signal, it controls the external water supply valve to close.
