Description

Technical Field

[0001] The utility model relates to the technical field of intelligent street lamps, in particular to a protective device for an intelligent solar street lamp. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries to store electricity, ultra-bright LED lamps as light sources, and controlled by intelligent charge and discharge controllers to replace traditional public electric lighting street lights. Solar energy is an inexhaustible, clean, pollution-free and renewable green energy. Using solar power generation, photovoltaic energy is considered to be the most important new energy in the 21st century due to its unparalleled cleanliness, high safety, relative breadth and sufficiency of energy, long life and maintenance-free nature, which are not available in other conventional energy sources. Solar street lights do not require laying cables, AC power supply, or electricity bills; they use DC power supply and control; they have the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, and economical and practical. They can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places. Most of the LED lamp beads used for lighting and various electronic components used to control the circuits in street lights are installed in the lamp holder, so the lamp holder shell plays a protective role to prevent the LED lamp beads and electronic components from being damaged by external factors.

[0003] The lamp holder is generally divided into an upper shell part and a lower shell part. The upper shell part and the lower shell part form a certain accommodating cavity for installing lamp beads and electronic components. In order to ensure a good heat dissipation effect inside the lamp holder, some street lamps will open heat dissipation holes in the lower shell part of the lamp holder, and then these heat dissipation holes are always in an open state, which makes it easy for external dust and other impurities to enter the interior of the lamp holder through the heat dissipation holes. As the use time increases, it is easy to cause the internal environment of the lamp holder to deteriorate, thereby causing a certain impact on the normal use and service life of the lamp beads and electronic components. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a protective device for an intelligent solar street lamp, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a protective device for an intelligent solar street lamp, comprising an upper shell of a lamp head, a lower shell of a lamp head and a plurality of rectangular heat dissipation grooves opened on the lower shell of the lamp head, a plurality of the heat dissipation grooves are plugged with copper baffles, and a connecting shaft is rotatably installed inside the heat dissipation groove, the baffles are slidably connected to the connecting shaft, a guide rail is provided on the upper surface of the lower shell of the lamp head, a U-shaped rod is slidably installed on the guide rail, a rotating shaft is connected between the U-shaped rod and the baffle, and a memory alloy spring is connected between the U-shaped rod and the lower shell of the lamp head.

[0008] Optionally, the width of the baffle is greater than the width of the heat dissipation slot, and the baffle passes through the heat dissipation slot.

[0009] Optionally, a connecting groove is formed on the outer surface of the connecting shaft, the connecting groove has the same thickness as that of the blocking piece, and the blocking piece is slidably inserted into the connecting groove.

[0010] Optionally, the plurality of heat dissipation slots are distributed in a linear array, and the length direction of the guide rail is parallel to the array direction of the plurality of heat dissipation slots.

[0011] Optionally, a connecting plate integrally formed therewith is provided on the lower shell of the lamp holder, and one end of the memory alloy spring is fixedly connected to the connecting plate.

[0012] Optionally, the U-shaped rod is provided with a convex plate integrally formed therewith, and one end of the memory alloy spring away from the connecting plate is fixedly connected to the convex plate.

[0013] (III) Beneficial effects

[0014] The utility model provides a protective device for an intelligent solar street lamp, which has the following beneficial effects:

[0015] 1. To achieve the purpose of automatically controlling the opening and closing state of the heat dissipation slot according to the temperature inside the lamp holder. When the lamp holder does not need to dissipate heat, the baffle will block the heat dissipation slot. When the lamp holder needs to dissipate heat, the baffle will open the heat dissipation slot and dissipate heat by deflecting. Therefore, the lamp holder can ensure effective heat dissipation while reducing the amount of dust entering the lamp holder to a certain extent, so that the interior of the lamp holder can be kept clean for a longer time, and dust and other impurities will not easily affect the normal use and service life of the lamp beads and electronic components, and improve the protection ability of the lamp holder to a certain extent;

[0016] 2. The higher the temperature inside the lamp holder, the longer the memory alloy spring will increase, the larger the opening of the heat dissipation slot will be, and the better the heat dissipation effect will be. On the contrary, the opening of the heat dissipation slot will be larger or even closed. Therefore, the opening of the heat dissipation slot can be adaptively adjusted according to the temperature inside the lamp holder, which can improve the protection effect of the lamp holder and improve its automation degree at the same time.

[0017] 3. The baffle is made of metallic copper, and a part of the baffle extends out of the lamp holder, so it can assist in heat dissipation inside the lamp holder. When the baffle is deflected, the baffle will continue to extend out of the lamp holder through the heat dissipation groove, thereby increasing the outward extension of the baffle, and then increasing its contact area with the outside air, so it can improve the heat dissipation capacity, and by accelerating the heat dissipation speed and allowing the heat dissipation groove to be closed as soon as possible, it can further reduce the opening time of the heat dissipation groove, which plays a positive role in preventing dust from entering.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figures 1 to 6The utility model provides a technical solution: an embodiment of a protective device for an intelligent solar street lamp, comprising an upper housing 10 of a lamp head, a lower housing 11 of a lamp head, and five rectangular heat dissipation slots 2 opened on the lower housing 11 of the lamp head, wherein the five heat dissipation slots 2 are distributed in a linear array, and copper baffles 3 are inserted into the interior of the five heat dissipation slots 2, wherein the width of the baffles 3 is greater than the width of the heat dissipation slots 2, and the baffles 3 penetrate the heat dissipation slots 2, and a connecting shaft 7 is rotatably installed inside the heat dissipation slots 2, wherein the baffles 3 are slidably connected to the connecting shaft 7, and a connecting groove 701 is opened on the outer surface of the connecting shaft 7, wherein the thickness of the connecting groove 701 is the same as that of the baffles 3, and the baffles 3 is slidably inserted into the connection groove 701, and a guide rail 5 is provided on the upper surface of the lower housing 11 of the lamp holder, and the length direction of the guide rail 5 is parallel to the array direction of the five heat dissipation grooves 2. A U-shaped rod 4 is slidably installed on the guide rail 5, and a rotating shaft 6 is connected between the U-shaped rod 4 and the blocking piece 3, and a memory alloy spring 8 is connected between the U-shaped rod 4 and the lower housing 11 of the lamp holder, and a connecting plate 9 integrally formed with the lower housing 11 of the lamp holder is provided, and one end of the memory alloy spring 8 is fixedly connected to the connecting plate 9, and a convex plate 401 integrally formed with the U-shaped rod 4 is provided, and one end of the memory alloy spring 8 away from the connecting plate 9 is fixedly connected to the convex plate 401.

[0027] In the initial state, the baffle 3 is slightly tilted in the horizontal direction. At this time, the upper and lower surfaces of the baffle 3 are respectively against the opposite side edges of the upper and lower openings of the heat dissipation slot 2, so the baffle 3 can completely block the heat dissipation slot 2 (such as Figure 3 and Figure 4 As shown), the interior of the upper shell 10 of the lamp cap and the lower shell 11 of the lamp cap are sealed, and impurities such as dust from the outside are effectively prevented from entering the interior of the upper shell 10 of the lamp cap and the lower shell 11 of the lamp cap from the interior of the heat dissipation groove 2 (that is, the interior of the lamp cap). When the internal temperature of the upper shell 10 of the lamp cap and the lower shell 11 of the lamp cap increases, the length of the memory alloy spring 8 increases due to the heat, thereby pushing the U-shaped rod 4 to slide along the length direction of the guide rail 5, and the U-shaped rod 4 then pushes the baffle 3 to slide through the rotating shaft 6. During this process, the baffle 3 will slide along the connecting groove 701, and at the same time, the baffle 3 will also drive the connecting shaft 7 to rotate counterclockwise through the connecting groove 701. Therefore, the baffle 3 will deflect in the counterclockwise direction under the action of the U-shaped rod 4 and the connecting shaft 7, thereby opening the heat dissipation groove 2 and dissipating heat. Moreover, the higher the temperature inside the lamp cap, the more the length of the memory alloy spring 8 will increase, the larger the opening of the heat dissipation groove 2 will be, and the better the heat dissipation effect will be. Moreover, due to the limitation of the length of the memory alloy spring 8 itself, the baffle 3 can only be flipped to a vertical state at most;

[0028] When the temperature inside the lamp holder drops, the memory alloy spring 8 will also slowly contract and slowly close the heat dissipation slot 2, ultimately achieving the purpose of automatically controlling the opening and closing state of the heat dissipation slot 2 according to the temperature inside the lamp holder;

[0029] The baffle 3 is made of metallic copper, and a part of the baffle 3 extends outward from the lamp holder, so it can assist in heat dissipation inside the lamp holder. Moreover, when the baffle 3 is deflected, the baffle 3 will continue to extend outward from the lamp holder through the heat dissipation slot 2, thereby increasing the outward extension amount of the baffle 3, and then increasing its contact area with the outside air, thereby improving the heat dissipation capacity, accelerating the heat dissipation speed, and allowing the heat dissipation slot 2 to be closed as soon as possible.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
