DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example:

[0042] See also Figure 1-Figure 8 The present invention provides a technical solution: a multifunctional street lamp shade structure, including a street lamp pole 1, a fixed shell 2 is fixedly installed on the top of the street lamp pole 1, a heat dissipation hole 6 is 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-axle motor, a fan blade 36 is fixedly installed on one end of the motor 5, and a limit plate 37 is fixedly installed on the other end of the motor 5. The motor 5 is fixedly installed in the inner wall of the bottom end of the fixed shell 2, and a heat dissipation mesh frame that can be removed by bolts is arranged on the outside of the fixed shell 2, one end of the fan blade 36 on the motor 5 is located on the outside of the fixed shell 2, and is also located in the heat dissipation mesh frame, and the gap of the heat dissipation mesh frame is small, which can be ventilated.

[0043] A heat dissipation mechanism 9 is provided in the fixed shell 2, and the heat dissipation mechanism 9 includes a heat dissipation plate 25, a cam column 23, a first movable column 27, a second push column 28 and an arc rod 29. The cam column 23 drives the second push column 28 to reciprocate through the arc rod 29 and the first movable column 27, and drives the heat dissipation plate 25 to reciprocate in the fixed shell 2. When the heat dissipation plate 25 reciprocates, the rapid flow of air in the fixed shell 2 is increased, and the heat dissipation in the fixed shell 2 is accelerated through the heat dissipation holes 6.

[0044] In this embodiment, the heat dissipation mechanism 9 also includes a first rotating column 22, a fixed plate 26 and a second fixed column 33. The 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 fixed 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 to the heat dissipation plate 25 and the fixed plate 26. Ventilation holes are opened at equal intervals inside the fixed plate 26. The top end of the fixed plate 26 is fixedly connected to the inner wall of the fixed shell 2, and the fixed plate 26 and the cam column 23 do not contact each other.

[0045] In this embodiment, the cam column 23 is in sliding contact with the arc rod 29. When the cam column 23 rotates, it drives the arc rod 29 to reciprocate. Both ends of the arc rod 29 are fixedly connected to the second push column 28. Both sides of the first movable column 27 are fixedly connected to the second push column 28. The first movable column 27 and the arc rod 29 are not connected to each other and are distributed on the side of the second push column 28 at the same time. The heat sink 25 is close to the heat dissipation hole 6, and a buffer pad is provided on the side of the heat sink 25 facing the heat dissipation hole 6. The buffer pad is made of PVC (polyvinyl chloride) soft board, and the PVC soft board has excellent waterproof performance. Yes, because the presence of hydrogen atoms in the PVC molecular structure makes it have good water resistance, and the PVC soft board has a certain elasticity. When subjected to external force, it can undergo elastic deformation, thereby playing a buffering role. When the heat sink 25 contacts the inner wall of one side of the heat dissipation hole 6, the heat sink 25 can be prevented from hitting the inner wall of the fixed shell 2 and damaging the heat sink 25. The adjacent sides of the heat sink 25 and the fixed plate 26 are fixedly installed with hinge seats 31, and a third connecting column 32 is arranged between two adjacent hinge seats 31. The heat sink 25 can adjust the distance between the fixed plate 26 through the hinge seat 31 and the third connecting column 32.

[0046] During operation, the third rotating gear 35 is driven to rotate through the forward rotation of the motor 5. When the third rotating gear 35 rotates, the cam column 23 is driven to rotate through the second rotating gear 24 and the first rotating column 22. When the cam column 23 rotates, the arc rod 29 moves, and the other end of the arc rod 29 is fixedly connected to the first movable column 27. In this way, the first movable column 27 will drive the heat sink 25 to move toward the side of the fixed plate 26 through the hinge seat 31 and the third connecting column 32. At the same time, the heat sink 25 will squeeze the first compression spring 30 when it moves. When the cam column 23 is separated from the arc rod 29, the heat sink 25 will move toward the side of the heat dissipation hole 6 under the action of the first compression spring 30. Through the reciprocating motion of the heat sink 25, the heat sink 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.

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

[0048] The first rotating plate 34 is fixedly mounted on one end of the limiting plate 37, and the second rotating plate 34 is fixedly mounted on the other end of the second compression spring 38. The first rotating plate 34 passes through the output shaft of the motor 5, and 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, and the shapes of the first inclined surface block and the second inclined surface block are both trapezoidal. The first inclined surface block and the second inclined surface block are respectively provided with a right-angled side and an inclined surface plate. When the first rotating plate 34 rotates forward, the second rotating plate 39 will be driven to rotate through the right-angled side of the trapezoid and the right-angled side of the second rotating plate 39. Conversely, when the inclined surface side of the first rotating plate 34 contacts the inclined surface side of the second rotating plate 39, the first rotating plate 34 will not drive the rotating plate 39 to rotate when it rotates.

[0049] The interior of the second fixed column 33 is provided with a sliding tooth block that drives the extrusion spring, and the outer side of the second rotating plate 39 is also provided with a limiting tooth block, and the outer sides of the sliding tooth block and the limiting tooth block are both provided with a straight edge and an inclined edge, the sliding tooth block is located between two adjacent limiting tooth blocks, and the straight edge of the sliding tooth block contacts the right-angled edge of one limiting tooth block, and the inclined edge of the sliding tooth block contacts the inclined edge of the other limiting tooth block, and when the motor 5 rotates forward, the second rotating plate 39 will contact the inclined edge of the sliding tooth block through the inclined edge of the limiting tooth block when it rotates, that is, the sliding tooth block in the second fixed column 33 will not hinder the rotation of the second rotating plate 39, and when the motor 5 is reversed, 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] A straight up and down sliding bar and a sliding bar groove are provided between the first rotating plate 34 and the output shaft of the motor 5 to facilitate the working movement of the first rotating plate 34 .

[0051] When it rains or snows, the motor 5 is controlled to reverse. When the motor 5 reverses, it will drive the first rotating plate 34 to rotate. When the first rotating plate 34 rotates in the opposite direction, it will contact the second rotating plate 39 through the inclined plate, but will not drive the second rotating plate 39 to rotate. At the same time, since the height of the second rotating plate 39 is fixed, the first rotating plate 34 will move downward and squeeze 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 operation of the lamp in the fixed shell 2 will be dissipated through the fan blades 36 to avoid excessive temperature in the fixed shell 2.

[0052] See also Figure 9-Figure 15 The present invention provides a technical solution: in this embodiment, the fixed shell 2 also includes a cleaning mechanism 8 and an adjusting mechanism 10, the adjusting mechanism 10 includes a connecting tube 40, a third push column 41, a fourth connecting column 42 and a fourth rotating gear 43, the top of the fourth connecting column 42 is fixedly connected to the second push column 28, the end of the connecting tube 40 is fixedly connected to the second connecting water pipe 17, the third push column 41 and the fourth connecting column 42 both pass through the connecting tube 40, a cavity 48 is provided in the connecting tube 40, one end of the third push column 41 is fixedly installed with a first piston block 45, 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, the outer sides of the third push column 41 and the fourth connecting column 42 are fixedly installed with second rack columns 44, and the two adjacent second rack columns 44 are meshingly connected with the fourth rotating gear 43. The two adjacent second rack columns 44 are symmetrically distributed about the center axis of the fourth rotating gear 43. The limiting ring block 50 and the limiting plate 51 are respectively fixedly installed in the cavity 48, and the second piston column 47 is movably installed inside the limiting plate 51, and the other end of the second piston column 47 is in contact with the limiting ring block 50.

[0054] In this embodiment, a water collecting box 3 is fixedly installed on the side of the street light pole 1, a first connecting water pipe 7 is arranged in the water collecting box 3, and the other end of the first connecting water pipe 7 is connected to the connecting cylinder 40, a first piston column 49 is arranged in the first connecting water pipe 7, and the first piston column 49 and the first piston block 45 are located on the same straight line.

[0055] A water pump is provided in the water collecting tank 3 , and the water pump works together with the motor 5 when the motor 5 rotates forward. The water pump cleans the lampshade 4 by passing the rainwater collected in the water collecting tank 3 through the first connecting water pipe 7 , the connecting tube 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 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 plate 51, and 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 plate 51. At the same time, the limiting plate 51 is provided with a second water flow channel around the second piston column 47. Both the first water flow channel and the second water flow channel are convenient for the water flow channel in the cavity 48.

[0057] When in use, water in the water storage tank 3 will flow into the cavity 48 of the connecting tube 40 through the first connecting water pipe 7. When the second push plate 28 moves toward the side of the fixed plate 26, the second push plate 28 will drive the second piston block 46 to move in the cavity 48 in the connecting tube 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, through 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 closed by the two second piston blocks 46. When the second push column 28 moves in the opposite direction, the second push column 28 will drive the fourth connecting column 42 to move. And make the second piston block 46 move in the opposite 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 the 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 passes through the limiting ring block 50 and the limiting plate 51 to make the water flow to the second connecting water pipe 17, and the lampshade 4 is sprayed with water through the nozzle 18 for cleaning, and because the second push column 28 performs reciprocating motion, the water flowing into the cavity 48 will continue to intermittently flow out through the second connecting water pipe 17 to clean the lampshade 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 shell 2. The first rack column 14 passes through the first fixed column 21. The first rack column 14 is meshed and connected 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. A first pushing column 13 is movably installed on the other end of the first connecting column 15. The first pushing column 13 is fixedly connected to the cleaning brush 12.

[0059] In this embodiment, a nozzle 18 is provided on the second connecting water pipe 17, and the spraying direction of the nozzle 18 is toward the lampshade 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 opened on the inner wall of the fixed shell 2.

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

[0061] When in use, the first rack column 14 is driven to move through the second pushing column 28. 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. The other 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 wet lampshade 4. Since the second pushing column 28 performs reciprocating motion, the cleaning brush 12 will repeatedly clean the lampshade 4 to ensure that there is no water on the lampshade and increase the brightness of the street lamp.

[0062] The cleaning mechanism and the adjusting mechanism cooperate with each other, and the reciprocating motion of the second pushing column is used to drive the movement of related parts, so that the water in the water collecting tank intermittently flows to the nozzle, and the lampshade is sprayed with water to clean. At the same time, the cleaning brush repeatedly cleans the wet lampshade under the linkage action of the first rack column, the first rotating gear, the first connecting column and the first pushing column, so as to ensure that the surface of the lampshade is clean and no water stains remain, thereby increasing the brightness of the street lamp, improving the lighting effect of the street lamp, reducing the light loss caused by the dirty lampshade, and improving the lighting quality and energy 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, which ensures the stability of the cleaning brush during cleaning, prevents the cleaning brush from detaching from the lamp cover, ensures the smooth progress of the cleaning work, and improves the reliability and effectiveness of cleaning.

[0064] The working principle of this embodiment is as follows: the third rotating gear 35 is driven to rotate by the forward rotation of the motor 5. When the third rotating gear 35 rotates, it will drive 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 rod 29 will move, and the other end of the arc rod 29 is fixedly connected to the first movable column 27. In this way, the first movable column 27 will drive the heat sink 25 to move toward the side of the fixed plate 26 through the hinge seat 31 and the third connecting column 32. At the same time, the heat sink 25 will squeeze the first compression spring 30 when it moves. When the cam column 23 is separated from the arc rod 29, the heat sink 25 will move toward the side of the heat dissipation hole 6 under the action of the first compression spring 30. Through the reciprocating motion of the heat sink 25, the heat sink 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 drives the second piston block 46 to move in the cavity 48 in the connecting cylinder 40 through the third connecting column 42, and a partition is formed in the cavity 48 by the two second piston blocks 46. At the same time, through the cooperation of the second rack column 44 and the fourth rotating gear 43, the third push column 41 drives the first piston block 45 to move and increases the capacity of the space closed by the two second piston blocks 46. When the second push column 28 moves in the reverse direction, the second push column 28 drives the fourth connecting column 42 to move and causes 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 and increases the capacity of the space closed by the two second piston blocks 46. The fourth rotating gear 43 enables the third push column 41 to drive 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 passes through the limiting ring block 50 and the limiting plate 51 to flow into the second connecting water pipe 17, and the lampshade 4 is sprayed with water through the nozzle 18 for cleaning. Since the second push column 28 performs reciprocating motion, the water flowing into the cavity 48 will continue to flow out through the second connecting water pipe 17 intermittently and clean the lampshade 4.

[0066] The first rack column 14 is driven to move by the second pushing column 28. 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. The other 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 wet lampshade 4. Since the second pushing column 28 performs reciprocating motion, the cleaning brush 12 will repeatedly clean the lampshade 4 to ensure that there is no water on the lampshade and increase the brightness of the street lamp.

[0067] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. 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.
