Description

Technical Field

[0001] The invention relates to the field of solar lamps, in particular to a solar lamp with high heat dissipation. Background Art

[0002] Solar lamps are generally mainly outdoor street lamps. When street lamps are lit for a long time, they are prone to heat up, resulting in heat accumulation, which can easily affect the service life. For this reason, a heat dissipation mechanism is installed on the solar lamp to help the street lamp dissipate heat. The existing solar lamps can effectively capture the wind in the environment through the setting of the induced draft duct, and change the direct direction of the natural wind on the lamp head, so that the wind blows directly vertically to the lamp head, greatly speeding up the air flow speed around the lamp head, thereby effectively speeding up the heat dissipation and effectively reducing the heat accumulation at the lamp head. In addition, with the setting of the wind gathering component, it can effectively capture wind from different wind directions. Thereby, there is always wind entering the duct, and the top of the lamp head can always be blown by vertical natural wind, which effectively ensures that the duct accelerates the flow of air around the lamp head and maintains efficient and stable heat dissipation of the lamp head. However, in actual use, the wind is captured by the wind gathering cover in the wind gathering component, but there are a lot of impurities in the air, so the impurities will also enter the air duct along the wind gathering cover. Over time, a large amount of fixed impurities will accumulate in the air duct, which will affect normal ventilation. Secondly, in windless weather, the wind gathering component will lose its function and cannot dissipate heat for the street lamp. For this reason, we propose a solar lamp with high heat dissipation.

A plurality of groups of air inlet pipes are connected around the air gathering shell, and a group of one-way valves are respectively installed on the plurality of groups of air inlet pipes. The end of the air inlet pipe away from the air gathering shell is connected to the air gathering cover. The top of the air gathering shell is connected to an air guide pipe, and a one-way valve two is installed on the air guide pipe. An exhaust pipe is connected between the air guide pipe and a group of air gathering shells, and a one-way valve three is installed on the exhaust pipe.

[0004] Preferably, the top end of the air duct is connected to the inner cavity of the support rod, one end of the support rod is fixedly connected to the sealing box, the inner cavity of the sealing box and the inner cavity of the support rod are interconnected, and the inner cavity diameter of the support rod gradually decreases from the air duct to the sealing box.

[0005] Preferably, a lighting lamp is fixedly mounted on the bottom of the sealed box, and two sides of the sealed box are respectively connected to a plurality of discharge pipes, and the discharge ports of the discharge pipes are all aligned with the lighting lamp.

[0007] Preferably, the support rod is fixedly connected to the lamp pole, an L-shaped stabilizing plate is fixedly connected to the outer wall of the lamp pole, and a reinforcing bent rod is fixedly installed between the support rod and the L-shaped stabilizing plate.

[0008] Preferably, the support plate is fixedly mounted on the outer wall of the lamp pole, and a stabilizing triangular support frame is fixedly mounted between the support plate and the L-shaped stabilizing plate.

[0009] Preferably, the support plate is fixedly connected to the outer side of the L-shaped stabilizing plate with a reinforcement frame via fixing bolts.

[0011] Preferably, a mounting box is fixedly mounted on the mounting frame. Compared with the prior art, the beneficial effects of the present invention are: 1. In the absence of wind or when the wind force is relatively low, the present invention drives the piston to move up and down continuously in the inner cavity of the wind gathering shell through the drive of a stepper motor, thereby dissipating the heat of the lighting lamp; it also drives multiple groups of scrapers to move up and down continuously, and then continuously cleans impurities adhering to the filter screen through the scrapers to prevent the filter screen from being blocked by impurities; it can also drive the fan blades to rotate, and the rotation of the fan blades will accelerate the air flow around the stepper motor, thereby accelerating the heat dissipation of the stepper motor.

[0012] 2. When the present invention is in use, since the hood opening of the wind condensing hood is equipped with a filter, impurities in the air can be filtered out to prevent the impurities from clogging the air duct; since the exhaust pipe is installed between the air duct and a group of wind condensing hoods, when the exhaust pipe draws external air, the filter installed at the hood opening of the wind condensing hood can filter the extracted air to prevent impurities in the air from being drawn into the exhaust pipe.

[0013] 3. When the present invention is in use, the inner cavity diameter of the support rod gradually becomes smaller from the air guide tube to the sealed box. Due to the principle of cooling down of air flow from large holes to small holes, the air flow will be cooled in the process of passing through the inner cavity of the support rod and entering the inner cavity of the sealed box. Since the sealed box is filled with the smell of wormwood, the air flow entering the inner cavity of the sealed box is mixed with the smell of wormwood. Finally, the mixed air flow is blown onto the lighting lamp through the exhaust pipe, thereby speeding up the air flow around the lighting lamp, and the temperature of the air flow discharged from the exhaust pipe is relatively low, thereby effectively ensuring the heat dissipation of the lighting lamp. Secondly, the air flow discharged from the exhaust pipe contains the smell of wormwood. Wormwood has an insect repellent effect, which can drive away mosquitoes around the lighting lamp and prevent the mosquitoes around the lighting lamp from being too large and affecting the light.

[0014] 4. When the present invention is in use, it can dissipate heat for the lighting lamp regardless of whether there is wind or not. When dissipating heat in a windless environment, it can also clean the heat dissipation auxiliary components (the filter installed at the hood opening of the wind condenser) in a windy environment, thereby ensuring that the wind condenser can be used normally in a windy environment.

[0023] The support rod 6 is fixedly connected to the lamp pole 13, an L-shaped stabilizing plate 14 is fixedly connected to the outer wall of the lamp pole 13, and a reinforcing bent rod 15 is fixedly installed between the support rod 6 and the L-shaped stabilizing plate 14; the L-shaped stabilizing plate 14 and the reinforcing bent rod 15 are provided to make the connection structure between the support rod 6 and the lamp pole 13 stable.

[0024] The support plate 1 is fixedly mounted on the outer wall of the lamp pole 13 , and a stabilizing triangular support frame 16 is fixedly mounted between the support plate 1 and the L-shaped stabilizing plate 14 ; the stabilizing triangular support frame 16 and the L-shaped stabilizing plate 14 are provided so that the support plate 1 can be stably mounted on the outer wall of the lamp pole 13 .

[0025] The support plate 1 and the outer side of the L-shaped stabilizing plate 14 are fixedly connected with a reinforcement frame 17 by fixing bolts; the reinforcement frame 17 is provided to make the connection structure between the support plate 1 and the L-shaped stabilizing plate 14 stable.

[0026] A mounting frame 18 is fixedly mounted on the top of the lamp pole 13 , and a solar panel 19 is fixedly mounted on the mounting frame 18 ; the solar panel 19 absorbs solar energy to charge a storage battery installed in the mounting box 20 .

[0027] The mounting frame 18 is fixedly mounted with a mounting box 20; a battery and a controller are mounted in the mounting box 20, and the battery is electrically connected to the solar panel 19, and the battery can be charged by the solar panel 19; the battery is electrically connected to the controller through wires, and the controller is connected to the stepper motor 707, the lighting lamp 10 and other structures through line control; when the device is used daily, the controller is connected to the network control terminal through the controller, and the operator can remotely control the use of the device according to actual conditions through the network control terminal.

[0028] Working principle of the present invention: When the present invention is used daily, in windy weather, since multiple groups of wind gathering covers 5 are distributed in a circular array at the outer end of the wind gathering shell 801, the arrangement of multiple wind gathering covers 5 can capture wind in all directions circumferentially, effectively ensuring that wind energy can always be captured and act on the surface of the lighting lamp 10 under different wind directions. Since the cover opening of the wind gathering cover 5 is installed with a filter 4, impurities in the air can be filtered out to prevent the impurities from clogging the air guide 804; the wind captured by the wind gathering cover 5 enters the wind gathering shell 801 through the air inlet pipe 802, and the airflow in the wind gathering shell 801 enters the inner cavity of the support rod 6 through the air guide 804. The inner cavity diameter of the support rod 6 gradually decreases from the air guide 804 to the sealing box 9. Due to the principle of cooling the airflow from large holes to small holes, the airflow will cool down in the process of passing through the inner cavity of the support rod 6 and entering the inner cavity of the sealing box 9. Since the sealed box 9 will be filled with the smell of wormwood, the air entering the sealed box 9 will be filled with the smell of wormwood. The airflow in the inner cavity is mixed with the smell of wormwood, and finally the mixed airflow is blown onto the lighting lamp 10 through the exhaust pipe 11, thereby accelerating the air flow around the lighting lamp 10, and the temperature of the airflow discharged from the exhaust pipe 11 is relatively low, thereby effectively ensuring the heat dissipation of the lighting lamp 10. Secondly, the airflow discharged from the exhaust pipe 11 contains the smell of wormwood, and wormwood has an insect repellent effect, which can drive away mosquitoes around the lighting lamp 10 and prevent the mosquitoes around the lighting lamp 10 from being too large and affecting the light.

[0029] When there is no wind or the wind force is small, the stepper motor 707 is remotely started to drive the reciprocating screw 704 to rotate. The rotation of the reciprocating screw 704 will drive the lifting plate 701 to move up and down continuously. The continuous up and down movement of the lifting plate 701 will drive the piston rod 702 to move up and down continuously, thereby driving the piston 703 to move up and down continuously in the inner cavity of the wind gathering shell 801. When the piston 703 moves downward, the air outside the wind gathering shell 801 can be extracted through the exhaust pipe 806, and the airflow enters the air guide pipe 804 and the inner cavity of the wind gathering shell 801 through the exhaust pipe 806. When the piston 703 moves upward, the airflow in the air guide pipe 804 and the inner cavity of the wind gathering shell 801 can be squeezed into the inner cavity of the support rod 6 through the one-way valve 805, so that the lighting lamp 10 can be cooled; the continuous up and down movement of the lifting plate 701 will also drive the multiple sets of scrapers 3 to move up and down continuously, thereby continuously cleaning the filter 4 through the scrapers 3. At the same time, the rotation of the reciprocating screw 704 will drive the fan blade 708 to rotate, and the rotation of the fan blade 708 will accelerate the air flow around the stepper motor 707, thereby accelerating the heat dissipation of the stepper motor 707.

[0030] It should be noted that the stepper motor 707 needs to be waterproofed during installation. A sealing ring can be added to the shaft end of the stepper motor and a waterproof seat can be added to the wire outlet to achieve IP53. By using special waterproof end covers, special waterproof bases, and special treatment of the body, the IP65 standard can be achieved.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
