[0033] The working principle and technical effects of the above technical solution are as follows:

[0034] The utility model discloses a waterproof, heat-insulating and dust-proof street lamp, in which a solar photovoltaic panel 2 is fixed on the upper surface of a lamp housing 1, and can effectively collect solar energy and convert it into electrical energy and store it in a battery pack inside the lamp housing 1; thereby, the battery pack is used to supply power to a lighting body 3 and a heat dissipation mechanism, and the lighting body 3 can be an LED lamp tube or an LED light source, and the lighting effect is better; a plurality of heat dissipation holes 4 are evenly arranged on the lower surface of the lamp housing 1, and a heat dissipation mechanism is arranged inside the lamp housing 1 toward the battery pack and the lighting body 3, which can effectively improve the heat dissipation effect of the utility model and prevent damage caused by untimely heat dissipation; a dust-proof filter is connected inside the lamp housing 1, and the dust-proof filter is located on the inner side of the plurality of heat dissipation holes 4, and effectively filters and removes dust from the air entering the lamp housing 1, and prevents dust from entering the lamp housing 1 and affecting the internal electronic components.

[0035] The lamp housing 1 comprises: a lower housing 101, on which the lighting body 3, dust filter and heat dissipation holes 4 are arranged; an upper housing 102, which is sealed and slidably arranged in the snap-fitting groove above the lower housing 101 to ensure a sealed connection, and a sealing strip can also be arranged between the two to effectively prevent water, and the upper housing 102 is fixedly connected with the solar photovoltaic panel 2; a plugging end cap 103, and two plugging end caps 103 are relatively sealed and plugged into two side ports formed between the lower housing 101 and the upper housing 102. The lamp housing 1 is easy to disassemble or install as a whole, and is convenient for replacing various components inside it, and is easy to clean or repair; the two plugging end caps 103 can also be connected to the lower housing 101 and the upper housing 102 by screws to further improve the stability of the connection.

[0037] The blocking end cover 103 includes a die-cast aluminum outer shell and a rubber sealing plug glued inside the die-cast aluminum outer shell. The rubber sealing plug is sealed and plugged into the side port, has a good waterproof effect, and effectively prevents rainwater from entering the interior of the lamp housing 1.

[0038] The battery box of the battery pack is an engineering plastic molecular battery box. Since the battery box of the battery pack is an engineering plastic molecular battery box, it has good waterproof, heat-insulating and dust-proof properties, so that it can effectively protect the battery pack.

[0039] The heat dissipation holes 4 are diamond-shaped heat dissipation holes, which have a better heat dissipation effect.

[0040] The heat dissipation mechanism includes a heat dissipation fan installed in the lamp housing 1, and the air outlet of the heat dissipation fan is arranged toward the battery pack and the lighting body 3, which effectively performs heat dissipation treatment on the battery pack and the lighting body 3 and improves the heat dissipation effect.

[0041] The waterproof, heat-insulating and dust-proof street lamp also includes an installation arm 5; the installation arm 5 includes an upper support body 6 connected to the lamp housing 1, the upper support body 6 is fixedly connected to the vertical arm 7, and the vertical arm 7 is rotatably connected to the lower support body 8 connected to the lamp pole; the vertical arm 7 is rotatably connected to one end of the oblique arm 9, and the other end of the oblique arm 9 is rotatably connected to the support seat 10 slidably mounted on the lower support body 8; the middle part of the angle adjustment screw 11 rotatably mounted on the lower support body 8 is threadedly connected to the support seat 10.
