Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and in particular to an angle adjustment mechanism for a street lamp. Background Art

[0002] Street lights refer to lamps that provide lighting for roads. They generally refer to lamps within the road surface lighting range in traffic lighting. During the installation of street lights, the ratio of the height of the light pole to the road width is usually between 1:4 and 1:6. According to this ratio, the angle of the street light needs to be adjusted accordingly to ensure that the light can illuminate the appropriate range;

[0003] Although the existing street lamp angle adjustment mechanism can adjust the illumination angle of the lamp, it cannot adjust the range of the lamp irradiating the ground. When the lamp irradiates the road surface, the edge of the direct light cannot be aligned with the edge of the road surface. The edge position of the light source of the lamp irradiating the road surface cannot be adjusted, which easily causes the direct light source to illuminate the roadside buildings and cause glare. Summary of the invention

[0004] Technical issues solved

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a street lamp angle adjustment mechanism, which can effectively solve the problem that the street lamp angle adjustment mechanism in the prior art can only adjust the illumination angle of the street lamp but cannot adjust the edge position of the direct light.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The present invention provides a street lamp angle adjustment mechanism, comprising a mounting box mounted on a street lamp pole, a shell being rotatably mounted on a side of the mounting box away from the pole, and a driving assembly for driving the shell to rotate being arranged inside the mounting box;

[0010] The pushing component is fixedly installed inside the shell and is used to push the linkage rod to slide, thereby adjusting the rotation angle of the reflector.

[0011] Furthermore, a rotating connecting block is fixedly installed on one side of the shell facing the installation box, one end of the rotating connecting block extends into the interior of the installation box, the horizontal height of the rotating connecting block is lower than the horizontal height of the pushing component, and the driving component includes a gear set and a servo motor, and the servo motor drives the rotating connecting block to rotate through the gear set.

[0013] Furthermore, a guide rod is fixedly mounted on the linkage rod, and a strip through hole for the guide rod to pass through is provided on the lifting frame. The linkage rod drives the guide rod to slide left and right, and the guide rod slides left and right to drive the lifting frame to move up and down.

[0014] Furthermore, it also includes a cover plate, which covers the installation box and the outer shell, and the cover plate is fixedly connected to the installation box. An elastic sealing sleeve is arranged under the cover plate, and a sealing groove is arranged on the outer side of the outer shell. The lower end of the elastic sealing sleeve is inserted into the sealing groove on the outer side of the outer shell. Multiple groups of light box components are arranged at intervals to form a heat dissipation space, and the heat dissipation space is connected to the internal space of the elastic sealing sleeve.

[0015] Furthermore, a lower cover plate is fixedly installed below the shell, and a heat dissipation hole is arranged at a position of the lower cover plate corresponding to the heat dissipation space, and a filter plate is arranged inside the heat dissipation hole.

[0017] Furthermore, the pushing assembly includes a sliding rod slidably mounted on one end of the shell close to the installation box, one end of the sliding rod passes through the shell and abuts against the outer wall of the installation box, and an end of the sliding rod away from the linkage rod is fixedly mounted with a support plate, which abuts against the outer wall of the installation box, and an elastic member is provided on the shell to drive the support plate to move toward the installation box. Beneficial Effects

[0018] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0019] The present invention provides rotatable reflectors on both sides of the light panel.

[0020] In the present invention, by arranging an elastic sealing sleeve under the cover plate, the elastic sealing sleeve can be conveniently squeezed or stretched when the distance between the cover plate and the outer shell changes, so that the air pressure environment inside the elastic sealing sleeve can be changed, so that the external airflow can pass through the two adjacent box bodies along the heat dissipation holes and the air permeable holes, and the temperature between the two adjacent box bodies can be reduced, which can prevent the light panel inside the box from overheating and causing damage to the electrical components.

[0021] In the present invention, floating plates are provided at both ends of the lifting frame, and sealing plates are provided below the floating plates. In extreme weather, when the street lamp does not need to be used, the lifting frame can be driven to move toward the installation box by driving the linkage rod to move downward. The floating plates at both ends of the lifting frame will drive the sealing plates to move downward, so that the sealing plates block the filter holes on the filter plate, thereby preventing rainwater from entering the inner part of the outer shell through the filter holes under the blowing of strong winds.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] When the street lamp angle adjustment mechanism is used, the lamp will be adjusted to accurately illuminate the road surface by adjusting the rotation of the lamp to make full use of the light source. However, this adjustment method cannot adjust the edge position of the light source irradiated on the road surface when the height of the street lamp is fixed, which can easily cause the direct light source to illuminate the roadside buildings and cause glare (such as Fig. 9As shown in the figure, 7 represents the light pole, 4 represents the light box assembly, and 8 represents the range of direct reflected light).

[0040] To this end, an embodiment of the present invention provides a street lamp angle adjustment mechanism, the purpose of which is at least to control the reflection direction of the reflected light by adjusting the reflector 43, and to adjust the width range of the light reflected onto the road surface by rotating the reflector 43, so as to more accurately adapt to narrow roads.

[0041] Embodiment: A street lamp angle adjustment mechanism, such as Figure 1 - Figure 6 As shown, it includes a mounting box 1 mounted on a street lamp pole, a housing 3 is rotatably mounted on a side of the mounting box 1 away from the pole, and a driving assembly 11 for driving the housing 3 to rotate is arranged inside the mounting box 1;

[0042] A plurality of light box assemblies 4 are fixedly installed inside the housing 3. A light board 42 is arranged inside the light box assemblies 4. Reflective plates 43 are rotatably installed on both sides of the light board 42. A linkage rod 5 for driving the two reflective plates 43 to rotate is slidably installed above the light board 42.

[0043] The pushing assembly 6 is fixedly installed inside the housing 3 and is used to push the linkage rod 5 to slide, thereby adjusting the rotation angle of the reflector 43 .

[0044] In the present invention, by arranging rotatable reflectors 43 on both sides of the light board 42, when the driving component 11 drives the light box component 4 to rotate, the linkage rod 5 can be driven to slide by the pushing component 6, so that the linkage rod 5 can drive the reflector 43 to deflect the angle, thereby changing the angle of light reflected by the reflector 43. According to actual use needs, by controlling the rotation angle of the reflector 43, the edge position of the light irradiated downward by the light box component 4 can be adjusted, and the width of the light irradiated on the road surface by the light box component 4 can be more accurately controlled.

[0045] It should be noted that the linkage rod 5 slides through the plurality of light box assemblies 4 and slides on the light box assemblies 4, and the rotation angle of the reflector 43 is adjusted during the sliding process of the linkage rod 5;

[0046] Furthermore, if Figure 2 , Figure 4 As shown, a rotating connecting block 12 is fixedly installed on one side of the housing 3 facing the installation box 1, one end of the rotating connecting block 12 extends into the interior of the installation box 1, and the horizontal height of the rotating connecting block 12 is lower than the horizontal height of the pushing component 6. The driving component 11 includes a gear group 111 and a servo motor 112, and the servo motor 112 drives the rotating connecting block 12 to rotate through the gear group 111.

[0047] When adjusting the rotation angle of the outer shell 3, the servo motor 112 is driven to rotate first, and the servo motor 112 drives the rotating connecting block 12 to rotate through the gear set 111. The gear set 111 can convert a small torque into a large torque, and then can more easily drive the outer shell 3 to rotate, thereby achieving the effect of adjusting the illumination angle of multiple light box assemblies 4.

[0048] Furthermore, if Figure 6 As shown, the light box assembly 4 also includes a box body 41, a fixing plate 44 is fixedly installed inside the box body 41, the light board 42 is fixedly installed below the fixing plate 44, a lifting frame 45 is installed above the fixing plate 44 for sliding up and down, the lifting frame 45 spans the fixing plate 44, and a rotating connecting rod 47 is rotatably installed at both ends of the lifting frame 45, and the lower end of the rotating connecting rod 47 is rotatably connected to the back of the reflective plate 43.

[0049] When adjusting the rotation angle of the reflector 43, the lower end of the rotating connecting rod 47 can be pulled up or pressed down by driving the lifting frame 45 to slide upward or downward, so that the reflector 43 can be rotated with the end close to the light board 42 as the axis, thereby adjusting the irradiation angle of the light reflected from the reflector 43.

[0050] Furthermore, if Figure 8 As shown, a guide rod 46 is fixedly mounted on the linkage rod 5, and a strip through hole 4501 is provided on the lifting frame 45 for the guide rod 46 to pass through. The linkage rod 5 drives the guide rod 46 to slide left and right, and the guide rod 46 slides left and right to drive the lifting frame 45 to move up and down.

[0051] Among them, the guide rod 46 slides inside the strip through hole 4501. When the guide rod 46 slides driven by the linkage rod 5, the guide rod 46 drives the lifting frame 45 to move. The strip through hole 4501 is inclined, and the horizontal height of one end of the strip through hole 4501 facing the installation box 1 is higher than the end of the strip through hole 4501 away from the installation box 1.

[0052] Furthermore, if Figure 3 As shown, it also includes a cover plate 2, which covers the installation box 1 and the outer shell 3, and the cover plate 2 is fixedly connected to the installation box 1. An elastic sealing sleeve 21 is arranged below the cover plate 2, and a sealing groove 302 is arranged on the outer side of the outer shell 3. The lower end of the elastic sealing sleeve 21 is sleeved in the sealing groove 302 on the outer side of the outer shell 3. Multiple groups of light box assemblies 4 are arranged at intervals to form a heat dissipation space, and the heat dissipation space is connected to the internal space of the elastic sealing sleeve 21.

[0053] Among them, by arranging an elastic sealing sleeve 21 under the cover plate 2, the elastic sealing sleeve 21 can be conveniently squeezed or stretched when the distance between the cover plate 2 and the outer shell 3 changes, so that the air pressure environment inside the elastic sealing sleeve 21 can be changed, and the external airflow can pass through the two adjacent box bodies 41 along the heat dissipation holes 3101 and the air permeable holes 301, so as to cool down the space between the two adjacent box bodies 41 and avoid overheating of the lamp panel 42 inside the box body 41, which may cause damage to the electrical components.

[0054] Furthermore, if Figure 5 As shown, a lower cover plate 31 is fixedly installed below the housing 3 , and a heat dissipation hole 3101 is arranged at a position of the lower cover plate 31 corresponding to the heat dissipation space, and a filter plate 32 is arranged inside the heat dissipation hole 3101 .

[0055] Among them, by arranging a filter plate 32 under the shell 3, mosquitoes or debris from the outside can be prevented from entering the interior of the shell 3 through the heat dissipation holes 3101, thereby avoiding damage to the components of the light box assembly 4.

[0056] Furthermore, if Figure 7 As shown, a sliding hole 4101 is provided on the side of the box body 41, and both ends of the lifting frame 45 pass through the sliding hole 4101. The sliding hole 4101 can guide the lifting frame 45 to ensure that the lifting frame 45 only moves up and down. Floating plates 451 are fixedly installed at both ends of the lifting frame 45, and a sealing plate 33 is fixedly installed below the floating plate 451. The sealing plate 33 is used to seal on the filter plate 32.

[0057] Among them, by arranging floating plates 451 at both ends of the lifting frame 45 and arranging a sealing plate 33 below the floating plate 451, in extreme weather (rainstorm or windy day), if the street lamp is not needed at this time, by driving the linkage rod 5 to move in the direction of the installation box 1, the lifting frame 45 can be driven to move downward, and the floating plates 451 at both ends of the lifting frame 45 will drive the sealing plate 33 to move downward, so that the sealing plate 33 can block the filter hole 3201 on the filter plate 32, thereby preventing rainwater from entering the inside of the shell 3 through the filter hole 3201 under the blowing of strong wind.

[0058] It should be noted that in daily use, rainwater will not enter the interior of the housing 3 through the filter hole 3201, because the opening of the filter hole 3201 faces downward. Only in stormy weather, the rainstorm is blown into the interior of the filter hole 3201 by the wind.

[0059] Furthermore, if Figure 5As shown, the pushing assembly 6 includes a sliding rod 61 slidably mounted on one end of the shell 3 close to the installation box 1, and a linkage through hole 303 is provided on the shell 3 for the sliding rod 61 to pass through. One end of the sliding rod 61 passes through the shell 3 and abuts against the outer wall of the installation box 1, and a support plate 62 is fixedly mounted on the end of the sliding rod 61 away from the linkage rod 5, and the support plate 62 abuts against the outer wall of the installation box 1, and an elastic member 63 is provided on the shell 3 for driving the support plate 62 to move toward the installation box 1.

[0060] Among them, the horizontal height of the abutment plate 62 is higher than the horizontal height of the rotating connecting block 12. When the outer shell 3 rotates with the end of the rotating connecting block 12 close to the installation box 1 as the axis, the abutment plate 62 is always pressed against the side of the installation box 1 under the drive of the elastic member 63, which will make the sliding rod 61 extend outward from the inside of the outer shell 3 to a greater length, thereby achieving the purpose of driving the linkage rod 5 to move.

[0061] Working principle: when it is necessary to adjust the illumination range of the street lamp to adapt to a relatively narrow road surface, the servo motor 112 drives the gear set 111 to rotate, and the gear set 111 drives the rotating connecting block 12 to rotate counterclockwise, and the rotating connecting block 12 drives the shell 3 as a whole to rotate with the end of the rotating connecting block 12 close to the installation box 1 as the axis, so that the distance between the upper half of the shell 3 and the upper half of the installation box 1 is increased, so that the sliding rod 61 slides out of the shell 3 more, and at this time the sliding rod 61 drives the linkage rod 5 to slide synchronously inside the shell 3. When the linkage rod 5 slides toward the installation box 1, it will drive the lifting frame 45 inside the box body 41 to move downward as a whole, so that the reflector 43 located under the lifting frame 45 rotates, and the reflector 43 rotates downward with the end close to the lamp board 42 as the axis, so that the range of the lamp box assembly 4 directly irradiated on the ground is narrower, which is more suitable for some narrow roads, and avoids direct light source from irradiating vehicles or buildings on the roadside to cause glare.

[0062] In extreme weather, the lifting frame 45 can be lowered to the lowest position by driving the shell 3 to rotate counterclockwise, and the floating plates 451 at both ends of the lifting frame 45 can be lowered synchronously. When the floating plate 451 drops to the lowest point, the sealing plate 33 on the floating plate 451 can be sealed at the filter hole 3201 of the filter plate 32, which can prevent strong winds from blowing rainwater into the shell 3 and prevent the lamp body components inside the shell 3 from being damaged by moisture.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
