DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Example 1: Reference Figure 1-Figure 8 A heat dissipation structure of a high-power solar street lamp includes: a top plate 1, a bottom plate 2, lamp beads 3 and heat dissipation holes 4, wherein a plurality of lamp beads 3 are mounted on the bottom surface of the top plate 1, a bottom plate 2 is mounted on the bottom end of the top plate 1, a plurality of notches are opened on the bottom plate 2, lenses are mounted on the notches, the lamp beads 3 are arranged toward the lenses, a plurality of heat dissipation holes 4 are opened on the bottom plate 2, and the heat dissipation holes 4 are arranged adjacent to the lamp beads 3.

[0029] The principle of the above scheme is:

[0030] After the lamp bead 3 is installed on the top plate 1 , the bottom plate 2 is installed so that the lens on the bottom plate 2 is aligned with the lamp bead 3 . The lens is specifically a convex lens, and the heat dissipation hole 4 is arranged adjacent to the lamp bead 3 .

[0031] The beneficial effects of the above scheme are:

[0032] The lamp beads 3 and the heat dissipation holes 4 are arranged adjacent to each other, which simplifies the structural design and facilitates rapid cooling of the lamp beads 3 after the lamp beads 3 have been working for a long time.

[0033] Example 2: Reference Figure 1-Figure 8The bottom plate 2 is provided with a gas storage box 5, which is filled with carbon dioxide gas. The gas storage box 5 is placed between the bottom plate 2 and the top plate 1. A plurality of heat conducting plates 6 are mounted on the gas storage box 5. One end of the heat conducting plate 6 is placed below the bottom surface of the bottom plate 2, and the other end of the heat conducting plate 6 is placed in the gas storage box 5. An end of an exhaust pipe 7 is provided on the gas storage box 5, and the other end of the exhaust pipe 7 is provided with one end of a rubber column 8, and the other end of the rubber column 8 is arranged toward the lamp bead.

[0034] The heat conducting plate 6 is specifically a copper plate.

[0035] The principle of the above scheme is:

[0036] The gas storage box 5 is filled with carbon dioxide gas, and the other end of the rubber column 8 is arranged toward the lamp bead. When the lamp bead 3 fails and catches fire during operation, the fire source melts the rubber column 8, and the carbon dioxide gas in the gas storage box 5 can be sprayed toward the lamp bead 3 through the exhaust pipe 7 and extinguish the fire source. The remaining carbon dioxide gas is discharged through the heat dissipation hole 4.

[0037] The beneficial effects of the above scheme are:

[0038] The other end of the rubber column 8 is arranged toward the lamp bead 3, so that when the lamp bead 3 catches fire, the rubber column 8 quickly melts and sprays carbon dioxide gas to the fire source through the exhaust pipe 7 to extinguish the fire, thereby improving the safety of the device; at the same time, the heat dissipation hole 4 can reduce the pressure between the top plate 1 and the bottom plate 2 when extinguishing the fire.

[0039] Example 3: Reference Figure 1-Figure 8 The gas storage box 5 is provided with an end of a conduit 9 , and the conduit 9 is connected to the base plate 2 through a mounting seat 10 .

[0040] The principle of the above scheme is:

[0041] The conduit 9 is connected to the base plate 2 via a mounting seat 10 .

[0042] The beneficial effects of the above scheme are:

[0043] The mounting seat 10 provides support for the catheter 9 and increases the stability of the catheter 9 .

[0044] Example 4: Reference Figure 1-Figure 8 The other end of the catheter 9 is connected to a catheter 2 11 , and the inner diameter of the catheter 2 11 is greater than the inner diameter of the catheter 9 .

[0045] The principle of the above scheme is:

[0046] The inner diameter of the second conduit 11 is greater than that of the conduit 9 , and the other end of the conduit 9 is connected to the second conduit 11 .

[0047] The beneficial effects of the above scheme are:

[0048] The second conduit 11 can seal the other end of the conduit 9 .

[0049] Example 5: Reference Figure 1-Figure 8 A piston 12 is installed in the second conduit 11, one side of the piston 12 is connected to the inner wall of the second conduit 11 through a return spring 13, and a rod body 14 is installed on the other side of the piston 12 away from the gas storage box 5, and the rod body 14 is slidably connected to the round hole on the second conduit 11.

[0050] The principle of the above scheme is:

[0051] When the temperature outside the street lamp is high, the temperature of the carbon dioxide gas transferred by the heat conducting plate 6 is high, the volume of the carbon dioxide gas expands greatly, the piston 12 drives the rod body 14 to move away from the gas storage box 5, and the return spring 13 is stretched;

[0052] When the temperature outside the street lamp is low, the temperature of the carbon dioxide gas transferred to the heat conducting plate 6 is low, the volume of the carbon dioxide gas shrinks, the piston 12 drives the rod body 14 to move toward the gas storage box 5, and the return spring 13 is compressed.

[0053] The beneficial effects of the above scheme are:

[0054] The heat conducting plate 6 can transfer the temperature outside the street lamp to the carbon dioxide gas in the gas storage box 5 in a timely manner. The expansion and contraction of the carbon dioxide gas can drive the piston 12 and the rod body 14 to move along the conduit 2 11 .

[0055] Example 6: Reference Figure 1-Figure 8 The end of the rod body 14 outside the second conduit 11 is connected to the transverse plate 15, the transverse plate 15 is arranged parallel to the bottom plate 2, and the ends of multiple longitudinal plates 16 are installed on the transverse plate 15. The longitudinal plate 16 has a second heat dissipation hole 17, and the second heat dissipation hole 17 is staggered with the heat dissipation hole 4.

[0056] The principle of the above scheme is:

[0057] When the temperature outside the street lamp is high, the rod body 14 moves away from the gas storage box 5, and the rod body 14 drives the transverse plate 15 and the longitudinal plate 16 to move, and the heat dissipation hole 2 17 and the heat dissipation hole 4 are changed from staggered arrangement to conductive arrangement;

[0058] When the temperature outside the street lamp is low, the rod body 14 moves toward the gas storage box 5 , and the rod body 14 drives the transverse plate 15 and the longitudinal plate 16 to move, and the heat dissipation holes 17 and the heat dissipation holes 4 are arranged alternately.

[0059] The beneficial effects of the above scheme are:

[0060] The staggered arrangement of the heat dissipation hole 2 17 and the heat dissipation hole 4 can reduce the conduction area of ​​the heat dissipation hole 4. The reduction in the area of ​​the heat dissipation hole 4 can prevent dust or moisture outside the street lamp from entering into the bottom plate 2. When the lamp bead 3 is heated, the heat is transferred from the inside to the outside. The end of the heat dissipation hole 4 outside the street lamp will generate airflow due to the temperature difference, further preventing dust or moisture from entering into the bottom plate 2. When the temperature outside the street lamp is low, the heat dissipation hole 2 17 reduces the conduction area of ​​the heat dissipation hole 4 to prevent the temperature around the lamp bead 3 from being too low and causing damage to the lamp bead 3.

[0061] Example 7: Reference Figure 1-Figure 8 The longitudinal plate 16 is slidably connected to the bottom plate 2, and a transverse plate 2 is mounted on the other end of the longitudinal plate 16.

[0062] The principle of the above scheme is:

[0063] The other end of the longitudinal plate 16 is provided with a transverse plate 2.

[0064] The beneficial effects of the above scheme are:

[0065] One end of the longitudinal plate 16 is connected to the second transverse plate, and the second transverse plate cooperates with the transverse plate 15 to fix the longitudinal plate 16 , thereby improving the stability of the longitudinal plate 16 when sliding on the bottom plate 2 .

[0066] Example 8: Reference Figure 1-Figure 8 The bottom plate 2 is rotatably connected to a plurality of rotating shafts, and a plurality of rubber vibration sheets 18 are mounted on the side walls of the rotating shafts. The ends of the rubber vibration sheets 18 are rollingly matched with the longitudinal plates 16.

[0067] The principle of the above scheme is:

[0068] When the longitudinal plate 16 slides on the bottom plate 2 , the rubber vibration sheet 18 on the side wall of the rotating shaft rolls with the longitudinal plate 16 .

[0069] The beneficial effects of the above scheme are:

[0070] The rubber vibration sheet 18 and the longitudinal plate 16 are in rolling cooperation, so as to shake off the dust accumulated on the second heat dissipation hole 17 and the heat dissipation hole 4, thereby preventing the heat dissipation hole 4 and the second heat dissipation hole 17 from being blocked by dust.

[0071] Example 9: Reference Figure 1-Figure 8 , the heat conducting plates 6 are arranged in parallel.

[0072] The principle of the above scheme is:

[0073] The heat conducting plates 6 are arranged in parallel with each other, and a plurality of heat conducting plates 6 are placed between the bottom ends under the bottom surface of the bottom plate 2 to form an air guide channel, and the air guide channel can be in full contact with the flowing air in the environment.

[0074] The beneficial effects of the above scheme are:

[0075] After a plurality of heat conducting plates 6 are placed between the ends of the bottom surface of the bottom plate 2 to form a guide channel, they can be fully in contact with the flowing air, thereby increasing the absorption of the heat conducting plates 6 to the environment and further improving the efficiency of the heat conducting plates 6 in transferring temperature to the carbon dioxide gas.

[0076] Example 10: Reference Figure 1-Figure 8 The axis of the end of the conduit 9 is arranged parallel to the heat conducting plate 6 .

[0077] The principle of the above scheme is:

[0078] A plurality of heat conducting plates 6 are disposed in parallel between the ends of the gas storage box 5 and form an internal flow guiding channel.

[0079] The beneficial effects of the above scheme are:

[0080] The internal guide channel guides the carbon dioxide gas, so that the carbon dioxide gas affected by the temperature change can quickly flow through the internal guide channel to the conduit 9, or flow through the conduit 9 to the internal guide channel.
