Description

Technical Field

[0001] The present invention relates to the technical field of street lamp covers, and specifically to a multifunctional street lamp. Background Technique

[0002] With the development of the economy and the continuous improvement of the scientific and technological level, the lighting industry in our country has developed very rapidly. Street lamps are very common in daily life. When in use, street lamps are installed inside transparent street lamp covers, making them not easily damaged when in use.

[0003] In the past, street lamps may mainly rely on natural heat dissipation, such as simple hot air exchange through heat dissipation holes. However, this method has low heat dissipation efficiency. When the lamps work for a long time or the ambient temperature is relatively high, it is difficult to effectively reduce the temperature inside the lamps, resulting in accelerated aging of the lamps and shortened service life. Although some street lamps have heat dissipation devices, they may have a simple structure, such as only using fixed heat sinks, which cannot promote the rapid flow of air and the rapid dissipation of heat, and cannot meet the requirements of efficient heat dissipation.

Detailed implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0041] Embodiment:

[0042] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a multifunctional street lamp, including a street lamp pole 1, a fixed shell 2 is fixedly installed at the top of the street lamp pole 1, heat dissipation holes 6 are opened on the side of the fixed shell 2, a motor 5 is arranged inside the fixed shell 2, the motor 5 adopts a double-shaft motor, one end of the motor 5 is fixedly installed with a fan blade 36, the other end of the motor 5 is fixedly installed with a limiting plate 37, the motor 5 is fixedly installed in the bottom inner wall of the fixed shell 2, and a heat dissipation net frame that can be disassembled by bolts is arranged outside the fixed shell 2. One end of the fan blade 36 on the motor 5 is located outside the fixed shell 2 and is simultaneously located in the heat dissipation net frame. At the same time, the gaps of the heat dissipation net frame are small and can conduct ventilation.

[0043] A heat dissipation mechanism 9 is arranged in the fixed shell 2. The heat dissipation mechanism 9 includes a heat dissipation plate 25, a cam column 23, a first movable column 27, a second pushing column 28 and an arc-shaped rod 29. The cam column 23 drives the second pushing column 28 to move reciprocally through the arc-shaped rod 29 and the first movable column 27, and drives the heat dissipation plate 25 to move reciprocally in the fixed shell 2. When the heat dissipation plate 25 moves reciprocally, it increases the rapid flow of air in the fixed shell 2, and through the heat dissipation holes 6, it accelerates the rapid dissipation of heat in the fixed shell 2.

[0044] In this embodiment, the heat dissipation mechanism 9 further includes a first rotating column 22, a fixing plate 26 and a second fixing column 33. A second rotating gear 24 is fixedly installed on the outer side of the first rotating column 22. The cam column 23 is fixedly installed on the first rotating column 22. The first movable column 27 passes through the fixing plate 26, and a first compression spring 30 is arranged on the outer side of the first movable column 27. The two ends of the first compression spring 30 are respectively fixedly connected with the heat dissipation plate 25 and the fixing plate 26. Ventilation holes are equally spaced and penetrated in the interior of the fixing plate 26. The top end of the fixing plate 26 is fixedly connected with the inner wall of the fixed shell 2. The fixing plate 26 and the cam column 23 do not contact each other.

[0045] In this embodiment, the cam column 23 and the arc-shaped rod 29 are in sliding contact. When the cam column 23 rotates, it will drive the arc-shaped rod 29 to move reciprocally. Both ends of the arc-shaped rod 29 are fixedly connected with the second pushing column 28. Both sides of the first movable column 27 are fixedly connected with the second pushing column 28. The first movable column 27 and the arc-shaped rod 29 are not connected to each other, and are simultaneously distributed on the side of the second pushing column 28. The heat dissipation plate 25 is close to the heat dissipation holes 6, and a buffer pad is arranged on the side of the heat dissipation plate 25 facing the heat dissipation holes 6. The buffer pad is made of a PVC (polyvinyl chloride) soft board. The PVC soft board has excellent waterproof performance. Because of the existence of hydrogen atoms in the PVC molecular structure, it has good water resistance. At the same time, the PVC soft board has a certain elasticity. When subjected to an external force, it can undergo elastic deformation, thus playing a buffering role. When the heat dissipation plate 25 contacts the inner wall on one side of the heat dissipation holes 6, it can prevent the heat dissipation plate 25 from hitting the inner wall of the fixed shell 2 and damaging the heat dissipation plate 25. Hinge seats 31 are fixedly installed on the adjacent sides of the heat dissipation plate 25 and the fixing plate 26. A third connecting column 32 is arranged between two adjacent hinge seats 31. The heat dissipation plate 25 can adjust the distance from the fixing plate 26 through the hinge seats 31 and the third connecting column 32.

[0046] During operation, the forward rotation of the motor 5 drives the third rotating gear 35 to rotate. When the third rotating gear 35 rotates, it drives the cam column 23 to rotate through the second rotating gear 24 and the first rotating column 22. When the cam column 23 rotates, the arc-shaped rod 29 moves. The other end of the arc-shaped rod 29 is fixedly connected to the first movable column 27. In this way, the first movable column 27 will drive the heat dissipation plate 25 to move towards the fixed plate 26 side through the hinge seat 31 and the third connecting column 32. At the same time, when the heat dissipation plate 25 moves, it will squeeze the first compression spring 30. When the cam column 23 separates from the arc-shaped rod 29, the heat dissipation plate 25 will move towards the heat dissipation hole 6 side under the action of the first compression spring 30. Through the reciprocating movement of the heat dissipation plate 25, the heat dissipation plate 25 will accelerate the air flow in the fixed housing 2, so that the heat generated by the lamp is dissipated through the heat dissipation hole 6, reducing the temperature in the fixed housing 2.

[0047] In this embodiment, a second rotating plate 39 is movably installed between two adjacent second fixed columns 33. The top end of the second rotating plate 39 is fixedly installed with a third rotating gear 35. The second rotating gear 24 and the third rotating gear 35 are meshed and connected. The second fixed column 33 ensures that the rotation of the second rotating plate 39 remains stable.

[0048] In this embodiment, one end of the limit plate 37 is fixedly installed with a second compression spring 38. The other end of the second compression spring 38 is fixedly installed with a first rotating plate 34. The first rotating plate 34 passes through the output shaft of the motor 5. The output shaft of the motor 5 does not contact the second rotating plate 39. The top end of the first rotating plate 34 is provided with a first inclined surface block, and the bottom end of the second rotating plate 39 is provided with a second inclined surface block. The first inclined surface block and the second inclined surface block are meshed and connected. The shapes of both the first inclined surface block and the second inclined surface block are trapezoidal. The first inclined surface block and the second inclined surface block are respectively provided with a right-angled side and an inclined panel. When the first rotating plate 34 rotates forward, it will drive the second rotating plate 39 to rotate through the right-angled side of the trapezoid and the right-angled side of the second rotating plate 39. On the contrary, when the inclined side of the first rotating plate 34 contacts the inclined side of the second rotating plate 39, the rotation of the first rotating plate 34 will not drive the rotating plate 39 to rotate.

[0049] Inside the second fixed column 33, there is a sliding tooth block that drives the compression spring. On the outer side of the second rotating plate 39, there is also a limit tooth block. On the outer sides of both the sliding tooth block and the limit tooth block, there is a straight edge and an inclined edge. The sliding tooth block is located between two adjacent limit tooth blocks, and the straight edge of the sliding tooth block contacts the right-angle edge of one limit tooth block, and the inclined edge of the sliding tooth block contacts the inclined edge of the other limit tooth block. When the motor 5 rotates forward, when the second rotating plate 39 rotates, it will contact the inclined edge of the limit tooth block through the inclined edge of the sliding tooth block, that is, the sliding tooth block in the second fixed column 33 will not hinder the rotation of the second rotating plate 39. When the motor 5 rotates in reverse, the second rotating plate 39 is restricted by the sliding tooth block in the second fixed column 33 and cannot rotate. That is, when the first rotating plate 34 rotates, the second rotating plate 39 is in a fixed state, and the first rotating plate 34 will not drive the second rotating plate 39 to rotate.

[0050] Between the first rotating plate 34 and the output shaft of the motor 5, there are vertically straight sliding strips and sliding strip grooves, which facilitate the working movement of the first rotating plate 34.

[0051] When it rains or snows, control the motor 5 to rotate in reverse. When the motor 5 rotates in reverse, it will drive the first rotating plate 34 to rotate. When the first rotating plate 34 rotates in the reverse direction, it will contact the second rotating plate 39 through the inclined panel, but will not drive the second rotating plate 39 to rotate. At the same time, due to the fixed height of the second rotating plate 39, the first rotating plate 34 will move downward and compress the second compression spring 38, so that the heat dissipation plate 25 will not move in the fixed shell 2. In this way, the heat generated by the lamp working in the fixed shell 2 will be dissipated through the fan blades 36, avoiding too high a temperature in the fixed shell 2.

[0052] Please refer to Figures 9 - 15 In this embodiment, the fixed shell 2 further includes a cleaning mechanism 8 and an adjusting mechanism 10. The adjusting mechanism 10 includes a connecting cylinder 40, a third pushing column 41, a fourth connecting column 42, and a fourth rotating gear 43. The top end of the fourth connecting column 42 is fixedly connected to the second pushing column 28. The end of the connecting cylinder 40 is fixedly connected to the second connecting water pipe 17. The third pushing column 41 and the fourth connecting column 42 both pass through the connecting cylinder 40. There is a cavity 48 in the connecting cylinder 40. One end of the third pushing column 41 is fixedly installed with a first piston block 45, and one end of the fourth connecting column 42 is fixedly installed with a second piston block 46. The first piston block 45 and the second piston block 46 intermittently control the cleaning liquid to flow into the second connecting water pipe 17 in the cavity 48.

[0053] In this embodiment, second rack columns 44 are fixedly installed on the outer sides of the third push column 41 and the fourth connection column 42. Adjacent second rack columns 44 are meshed with a fourth rotating gear 43. The adjacent second rack columns 44 are symmetrically distributed about the central axis of the fourth rotating gear 43. A limiting ring block 50 and a limiting through plate 51 are fixedly installed in the cavity 48 respectively. A second piston column 47 is movably installed inside the limiting through plate 51. The other end of the second piston column 47 contacts the limiting ring block 50.

[0054] In this embodiment, a water collecting tank 3 is fixedly installed on the side of the street lamp pole 1. A first connecting water pipe 7 is arranged in the water collecting tank 3, and the other end of the first connecting water pipe 7 communicates with a connecting cylinder 40. A first piston column 49 is arranged in the first connecting water pipe 7. The first piston column 49 and the first piston block 45 are on the same straight line.

[0055] A water pump is arranged in the water collecting tank 3. The water pump works together with the motor 5 when it rotates forward. The water pump cleans the lamp shade 4 by pumping the rainwater collected in the water collecting tank 3 through the first connecting water pipe 7, the connecting cylinder 40 and the other connecting water pipe 27.

[0056] The first piston block 45 and the second piston block 46 are respectively located on both sides of the limiting ring block 50 and the limiting through plate 51. A first water flow channel is arranged on the middle side of the limiting slider 50. The second piston column 47 passes through the limiting through plate 51. A compression air bag is arranged on the outer side of the second piston column 47. The compression air bag is located between the limiting slider 50 and the limiting through plate 51. At the same time, second water flow channels are arranged around the second piston column 47 on the limiting through plate 51. Both the first water flow channel and the second water flow channel facilitate the water flow channel in the cavity 48.

[0057] During use, the water in the water storage tank 3 will flow through the first connecting water pipe 7 into the cavity 48 of the connecting cylinder 40. When the second push plate 28 moves towards the fixed plate 26, the second push plate 28 will drive the second piston block 46 to move in the cavity 48 of the connecting cylinder 40 through the third connecting column 42. A partition is formed in the cavity 48 by the two second piston blocks 46. At the same time, under the cooperation of the second rack column 44 and the fourth rotating gear 43, the third push column 41 will drive the first piston block 45 to move, and increase the capacity of the space enclosed by the two second piston blocks 46. When the second push column 28 moves in the reverse direction, the second push column 28 will drive the fourth connecting column 42 to move, and cause the second piston block 46 to move in the reverse direction. At the same time, through the second rack column 44 and the fourth rotating gear 43, the third push column 41 drives the first piston block 45 to move to one side of the cavity 48. When the first piston block 45 moves, it will push the first piston column 49 into the first connecting water pipe 7 and push the second piston column 47, so that the water in the cavity 48 will flow through the limiting ring block 50 and the limiting through plate 51 into the second connecting water pipe 17, and the water will be sprayed through the nozzle 18 to clean the lamp cover 4. Since the second push column 28 reciprocates, the water flowing into the cavity 48 will continuously flow out intermittently through the second connecting water pipe 17 to clean the lamp cover 4.

[0058] In this embodiment, the cleaning mechanism 8 includes a first rotating gear 11, a cleaning brush 12 and a first rack column 14. A first fixed column 21 is fixedly installed inside the fixed housing 2. The first rack column 14 passes through the first fixed column 21. The first rack column 14 is meshed with the first rotating gear 11. A second connecting column 16 is fixedly installed on the first rotating gear 11. A first connecting column 15 is movably installed on the second connecting column 16. The other end of the first connecting column 15 is movably installed with a first push column 13. The first push column 13 is fixedly connected with the cleaning brush 12.

[0059] In this embodiment, a nozzle 18 is provided on the second connecting water pipe 17. The spraying direction of the nozzle 18 faces the lamp cover 4. A sliding block 19 is fixedly installed on the side of the cleaning brush 12, and a sliding groove 20 matching the sliding block 19 is formed on the inner wall of the fixed housing 2.

[0060] The sliding block 19 and the sliding groove 20 can ensure the stability of the cleaning brush 12 during the cleaning work and prevent the cleaning brush from detaching from the lamp cover 4.

[0061] During use, the second pushing column 28 drives the first rack column 14 to move. When the first rack column 14 moves, it drives the first rotating gear 11 to rotate. When the first rotating gear 11 rotates, it drives the first connecting column 15 to rotate through the second connecting column 16. One end of the first connecting column 15 is movably connected to the first pushing column 13. In this way, the first pushing column 13 will drive the cleaning brush 12 to clean the water-stained lamp cover 4. Since the second pushing column 28 performs a reciprocating motion, the cleaning brush 12 will repeatedly clean the lamp cover 4, ensuring that there is no water on the lamp cover and increasing the illumination brightness of the street lamp.

[0062] The cleaning mechanism and the adjustment mechanism cooperate with each other. By using the reciprocating motion of the second pushing column to drive relevant components to move, the water in the water collection tank intermittently flows to the nozzle to spray and clean the lamp cover. At the same time, under the linkage action of components such as the first rack column, the first rotating gear, the first connecting column, and the first pushing column, the cleaning brush repeatedly cleans the water-stained lamp cover, ensuring that the surface of the lamp cover is clean without water stain residue, thereby increasing the illumination brightness of the street lamp, improving the lighting effect of the street lamp, reducing the light loss caused by the dirty lamp cover, and enhancing the lighting quality and energy utilization efficiency of the street lamp.

[0063] The sliding block on the side of the cleaning brush matches the sliding groove on the inner wall of the fixed shell, ensuring the stability of the cleaning brush during the cleaning work, preventing the cleaning brush from detaching from the lamp cover, ensuring the smooth progress of the cleaning work, and improving the reliability and effectiveness of the cleaning.

[0064] The working principle of this embodiment: The forward rotation of the motor 5 drives the third rotating gear 35 to rotate. When the third rotating gear 35 rotates, it drives the cam column 23 to rotate through the second rotating gear 24 and the first rotating column 22. When the cam column 23 rotates, the arc-shaped rod 29 moves. The other end of the arc-shaped rod 29 is fixedly connected to the first movable column 27. In this way, the first movable column 27 will drive the heat dissipation plate 25 to move towards the fixed plate 26 side through the hinge seat 31 and the third connecting column 32. At the same time, when the heat dissipation plate 25 moves, it will compress the first compression spring 30. When the cam column 23 separates from the arc-shaped rod 29, the heat dissipation plate 25 will move towards the heat dissipation hole 6 side under the action of the first compression spring 30. Through the reciprocating motion of the heat dissipation plate 25, the heat dissipation plate 25 will accelerate the air flow in the fixed shell 2, so that the heat generated by the lamp is dissipated through the heat dissipation hole 6, reducing the temperature in the fixed shell 2.

[0065] The second push plate 28 will drive the second piston block 46 to move in the cavity 48 of the connecting cylinder 40 through the third connecting column 42. By forming partitions with the two second piston blocks 46 in the cavity 48, and at the same time, under the cooperation of the second rack column 44 and the fourth rotating gear 43, the third push column 41 will drive the first piston block 45 to move, and increase the capacity of the space enclosed by the two second piston blocks 46. When the second push column 28 moves in the reverse direction, the second push column 28 will drive the fourth connecting column 42 to move, and cause the second piston block 46 to move in the reverse direction. At the same time, through the second rack column 44 and the fourth rotating gear 43, the third push column 41 drives the first piston block 45 to move to one side of the cavity 48. When the first piston block 45 moves, it will push the first piston column 49 into the first connecting water pipe 7, and push the second piston column 47, so that the water in the cavity 48 will flow through the limiting ring block 50 and the limiting through plate 51 to the second connecting water pipe 17, and spray water on the lamp cover 4 through the nozzle 18 for cleaning. Since the second push column 28 performs reciprocating motion, the water flowing into the cavity 48 will continuously and intermittently flow out through the second connecting water pipe 17, and clean the lamp cover 4.

[0066] The second push column 28 drives the first rack column 14 to move. When the first rack column 14 moves, it will drive the first rotating gear 11 to rotate. When the first rotating gear 11 rotates, it will drive the first connecting column 15 to rotate through the second connecting column 16. And the other end of the first connecting column 15 is movably connected with the first push column 13. In this way, the first push column 13 will drive the cleaning brush 12 to clean the water-stained lamp cover 4. And because the second push column 28 performs reciprocating motion, the cleaning brush 12 will clean the lamp cover 4 repeatedly, ensuring that there is no water on the lamp cover and increasing the illumination brightness of the street lamp.

[0067] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
