Description

Technical Field

[0001] The invention relates to the technical field of lighting equipment, and in particular to a combined cover structure of an LED street lamp. Background Art

[0002] LED street lights refer to street lights made with LED light sources. LED light sources are powered by low-voltage DC and produce high-efficiency white light synthesized from GaN-based power blue LEDs and yellow. They have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index, and can be widely used in roads.

[0003] In the application of LED street lights, lampshades are generally used in conjunction with them. Their main functions include adjusting light distribution, protecting lamps, and preventing pollution and insects. Lampshades scatter light to ensure that the light covers the area more evenly, thereby improving the lighting effect. Lampshades can also filter the strong light directly emitted by the light source, making it softer and avoiding discomfort to the eyes caused by glare.

[0004] LED street lights will generate heat when in use. When used for a long time at night, a large amount of heat will accumulate in the lampshade, which will reduce the service life of the lamp. In addition, street lights are installed on the roadside. Due to the constant changes in the external environment, the heat dissipation method and heat dissipation requirements of street lights are also different. For example, heat dissipation holes are opened on the lampshade, but in rainy and snowy weather, rainwater can easily enter the lampshade and cause damage to the components in the light source. When no holes are opened, it is not easy to discharge the heat in the lampshade in time, reducing the practicality of the lampshade. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] See also Figure 1-5 The present embodiment provides a combined cover structure of an LED street lamp, comprising a support column 1, the top of the support column 1 is fixedly connected to a support plate 2, the bottom of the support plate 2 is fixedly connected to a lampshade 3, and a bulb 31 is arranged in the lampshade 3; it also includes two baffles 32 slidably arranged in the lampshade 3 and a pull plate assembly driving the baffles 32 to move, and in windy weather, the baffles 32 are pulled by the pull plate assembly to open the lampshade 3; it also includes a wind cup 7, and the wind cup 7 is used to drive the pull plate assembly to rotate. After the wind cup 7 drives the pull plate assembly to open the lampshade 3, the wind cup 7 is separated from the pull plate assembly by the unlocking assembly, and the pull plate assembly is locked, and the pull plate assembly is locked by pulling The plate assembly opens the lampshade 3 to dissipate heat for the bulb 31 in a windy environment, and then the pull plate assembly is locked by the unlocking assembly to ensure that the pull plate assembly remains in an open state, and the wind circulates in the lampshade 3 to dissipate heat for the bulb 31. In a windy and rainy environment or a rainy environment, the pull plate assembly is passively closed by increasing the amount of rain, and the lampshade 3 is sealed. Then, the bulb 31 is dissipated by rain falling on the lampshade 3, thereby passively switching different heat dissipation methods in different environments, ensuring the stability of the working environment of the bulb 31, not causing damage to the bulb 31, and extending the service life of the bulb 31.

[0041] In an embodiment further provided by the present invention, the pulling plate assembly includes a rope wheel 52 rotatably arranged in the support plate 2, and two connecting ropes 51 are wound around the rope wheel 52. The ends of the two connecting ropes 51 pass through the lampshade 3 and are fixedly connected to the two baffles 32. A return spring 53 is provided on the outer sleeve of the connecting rope 51.

[0042] Furthermore, the pull plate assembly also includes a water tank 54 fixed to the outside of the baffle 32, the bottom of the water tank 54 is fixedly connected to a fixed rod 55, and a rotating plate 56 is rotatably connected to the outside of the fixed rod 55. A protrusion is provided in the water tank 54, and the protrusion is in active contact with the rotating plate 56, so that the rotating plate 56 rotates unidirectionally. When the water tank 54 collects rainwater, the water tank 54 is sealed.

[0043] Furthermore, a guide rod 57 is fixedly connected to the outside of the lampshade 3, and the guide rod 57 is in active contact with the rotating plate 56. When it rains after the pull plate is opened, the water tank 54 collects rainwater to increase the gravity of the baffle 32. When the gravity of the baffle 32 is greater than the friction force of the snap-in block 66, the snap-in block 66 moves out of the snap-in groove 68, so that the baffle 32 moves down to seal the lampshade 3, and after moving down, the rotating plate 56 is pushed open by the guide rod 57, the water tank 54 is opened, and the rainwater is discharged.

[0044] In an embodiment further provided by the present invention, a heat dissipation component is also included, which is used to dissipate heat from the bulb 31 when the weather is clear and there is no wind. The heat dissipation component includes a water tank 41, a sealing plate 44 is slidably arranged in the water tank 41, a water pump 42 is arranged at the bottom of the inner wall of the water tank 41, and a water inlet pipe 46 is arranged at the water inlet of the water pump 42. The water inlet pipe 46 is connected to the sealing plate 44, and the water outlet of the water pump 42 is connected to a heat dissipation pipe 43. The heat dissipation pipe 43 is wrapped around the outside of the bulb 31 and connected to the water tank 41. The water inlet pipe 46 is arranged in the form of a hose. When the sealing plate 44 moves due to gravity, it is ensured that the water inlet pipe 46 is always connected to the water pump 42, thereby ensuring the stability of the connection between the water pump 42 and the water inlet pipe 46.

[0045] In the embodiment provided by the present invention, the unlocking assembly includes a rectangular rod 61 fixed to the bottom end of the wind cup 7, and a fixed plate 62 is fixedly connected to the outside of the wind cup 7, a sliding rod 63 is slidably arranged in the support plate 2, the top end of the sliding rod 63 extends into the water tank 41 and is fixedly connected to an abutment plate 64, a limiting spring 65 is arranged on the outer sleeve of the sliding rod 63, the abutment plate 64 is movably abutted with the sealing plate 44, and the rectangular rod 61 is slidably arranged in the rope winding wheel 52. When it is windy, the wind cup 7 is driven to rotate by wind force to drive the rectangular rod 61 to rotate, so that the rope winding wheel 52 rotates synchronously, and the connecting rope 51 is wound up, thereby pulling the baffle 32 to open the lampshade 3 to ventilate and dissipate heat to the bulb 31.

[0046] Specifically, the unlocking component also includes a clamping block 66 slidably arranged in the sliding rod 63, and a clamping groove 68 adapted to the clamping block 66 is opened on the rope winding wheel 52. The bottom of the clamping block 66 is arc-shaped. When the clamping block 66 moves into the clamping groove 68, the direct friction force between the clamping groove 68 and the clamping block 66 is greater than the elastic force of the return spring 53 and the gravity of the baffle 32.

[0047] In the present invention, the unlocking assembly also includes a rotating rod 67 rotating in the support plate 2, the sliding rod 63 is fixedly connected to the limiting plate 69, one end of the rotating rod 67 is arranged in the fixed plate 62, and the other end of the rotating rod 67 is arranged in the limiting plate 69.

[0048] In the solution further provided by the present invention, the bottom of the inner wall of the water tank 41 is fixedly connected to a limit rod 71, a guide groove 72 is provided outside the wind cup 7, the limit rod 71 is slidably arranged in the guide groove 72, and the guide groove 72 is composed of an annular groove and a spiral groove (such as Figure 3 (As shown in the figure) when the limiting rod 71 moves to the lowest point of the annular groove, the wind cup 7 still moves out of the rope winding shaft with the rectangular rod 61, and the annular groove is inclined. Since the annular groove is inclined and the lowest point of the annular groove is connected to the spiral groove, when the wind cup 7 stops rotating, the wind cup 7 rotates in the opposite direction and moves downward due to gravity, so that the rectangular rod 61 moves into the rope winding wheel 52.

[0049] Furthermore, the heat dissipation assembly also includes a support spring 45 fixed to the bottom of the sealing plate 44, and the support spring 45 is fixedly connected to the bottom of the inner wall of the water tank 41. When the sealing plate 44 moves downward due to gravity, the support spring 45 is compressed. When the gravity of the sealing plate 44 disappears, the sealing plate 44 is driven to reset by the support spring 45. A small hole is opened on the water tank 41, and the small hole is located at the bottom of the sealing plate 44. When the amount of water in the water tank 41 increases and the sealing plate 44 moves downward, the small hole is opened to discharge excess water to ensure the amount of water in the water tank 41. A filter screen 47 is fixedly connected to the top of the water tank 41. The filter screen 47 is used to filter the water tank to prevent foreign objects such as fallen leaves from falling into the water tank 41.

[0050] When the street lamp is in a windy environment, the wind cup 7 is driven to rotate by the wind force, thereby driving the rectangular rod 61 to rotate synchronously, so that the rope pulley 52 rotates, and the connecting rope 51 is wound up, so that the baffle 32 moves to open the lampshade 3, so that the flowing wind is generated in the lampshade 3 for heat dissipation;

[0051] When the wind cup 7 rotates, the guide groove 72 moves outside the limiting rod 71, so that the wind cup 7 moves upward, driving the rectangular rod 61 to move out of the rope wheel 52, and when the wind cup 7 moves upward, the fixing plate 62 is driven to move synchronously, thereby driving the rotating rod 67 to rotate, thereby pushing the limiting plate 69 to move downward, pulling the sliding rod 63 to move downward synchronously, so that the clamping block 66 is clamped into the clamping groove 68, clamping the rope wheel 52, and offsetting the force of the return spring 53;

[0052] In a rainy environment, when the baffle 32 is opened, the water tank 54 moves upward, and the rotating plate 56 seals the bottom of the water tank 54 to collect rainwater. When the gravity of the rainwater and the elastic force of the return spring 53 are greater than the friction between the clamping rod and the clamping groove 68, the rope wheel 52 rotates to push the clamping rod upward, so that the rope wheel 52 rotates in the opposite direction, so that the baffle 32 moves downward and the lampshade 3 is closed;

[0053] When the baffle 32 moves downward, it drives the water tank 54 to move synchronously. When the rotating plate 56 of the water tank 54 moves to the guide rod 57, the rotating plate 56 is pushed open to discharge the rainwater in the water tank 54 to avoid accumulation.

[0054] When it rains, rainwater enters the water tank 41 through the filter 47, so that the amount of water in the water tank 41 increases, and the gravity on the sealing plate 44 increases and moves downward, driving the support spring 45 to compress, and the sealing plate 44 moves downward to push the abutment plate 64 to move downward, so that the sliding rod 63 moves downward synchronously, driving the clamping block 66 to move into the clamping groove 68, so as to clamp the rope wheel 52, and the wind cup 7 is pushed upward by the rotating rod 67, so that the rectangular rod 61 moves out of the rope wheel 52, even if there is wind to drive the wind cup 7 to rotate, it will not drive the rope wheel 52 to rotate;

[0055] When the sky is clear and there is no wind, the water in the water tank 41 is driven by the water pump 42 to enter the heat dissipation pipe 43, and the heat generated by the bulb 31 is taken away and circulated in the water tank 41 to achieve heat dissipation of the bulb 31.

[0056] 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.
