Description

Technical Field

[0001] The present invention relates to the technical field of advertising street lamps, and in particular to a smart street lamp with intelligent advertising display. Background Art

[0002] Smart street lights are a new type of street light that integrates multiple sensors, sensing devices, and functions. They not only have basic lighting functions, but also integrate traffic signals, communications, traffic signs, and other functions. They combine multiple poles into one, reducing the number of poles on the road and freeing up public space resources. Usually, a display screen is installed on this type of street lamp to play news or advertisements. The display screen is usually fixed on both sides of the middle part of the lamp pole using a mounting structure. Compared with traditional bare pole street lamps, this type of street lamp with a display screen is more likely to generate wind resistance in windy weather during use, making the street lamp more susceptible to wind force (tilting or falling due to loose display screen connectors), which is prone to safety hazards.

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] To this end, an embodiment of the present invention provides a smart street lamp with intelligent advertising display, the purpose of which is at least to adjust the position of the smart billboard 3 so that the smart billboard 3 can be installed on the lamp pole more stably, thereby reducing the impact of wind on the installation structure of the smart billboard 3.

[0022] Example: A smart street light with intelligent advertising display, such as Figure 1 - Figure 4 As shown, it includes a lamp pole 1 and a lamp head 2. Two smart billboards 3 are staggered in the middle of the lamp pole 1. The lamp pole 1 also includes: A support frame 11 is detachably mounted on the middle portion of the lamp post 1 and is used to provide sliding support for the two smart billboards 3. A drive gear 12 is rotatably mounted on the support frame 11, and a gear row 31 is fixedly mounted on the back of the smart billboard 3 to engage with the drive gear 12. A first drive motor 13 is also fixedly mounted on the support frame 11 to drive the two smart billboards 3 toward or away from each other. The cleaning component 4 is fixedly installed on the outside of the smart billboard 3 and is used to clean the outer end surface of the smart billboard 3 when the smart billboard 3 slides. The cleaning component 4 includes a cleaning roller 42, and a linkage frame 5 is provided on the side of the cleaning component 4 for driving the cleaning roller 42 to move closer to or away from the smart billboard 3.

[0023] In the present invention, a support frame 11 is provided on the lamp pole 1, and a first drive motor 13 is provided on the support frame 11, which can drive two relatively installed smart billboards 3 to approach each other. In windy weather, the first drive motor 13 is driven to rotate, so that the first drive motor 13 drives the two smart billboards 3 to approach each other, so that the two billboards 3 are adjusted from a staggered state to a mutually overlapping state, so that the wind-exposed area of ​​the two smart billboards 3 is smaller, and the impact of wind on the smart billboards 3 can be reduced. In addition, since the two smart billboards 3 overlap with each other, the cleaning component 4 is located on the side of the smart billboard 3 away from the lamp pole 1, and the middle part of the smart billboard 3 is clamped between the cleaning component 4 and the lamp pole 1, the stability of the installation of the smart billboard 3 can be further increased.

[0024] In addition, usually the smart billboard 3 is in a staggered state, which can have a larger volume and be more easily observed by pedestrians or vehicles, attracting the attention of pedestrians or people in vehicles. This is a common installation method for street light billboards.

[0025] Further, if Figure 4 As shown, there are four support frames 11, and the four support frames 11 are distributed into two groups with two pairs of them spaced apart in the upper and lower directions. The two support frames 11 in each group are symmetrically distributed on the outside of the lamp pole 1, and the two support frames 11 in each group are connected to each other through a rotating connection part 111. A U-shaped connecting rod 16 is provided between the upper and lower support frames 11 on the same side. When the four support frames 11 are installed on the lamp pole 1, the middle parts of the two connecting rods 16 are fixedly connected to each other by bolts; a mounting sleeve 112 is fixedly installed on the two support frames 11 located below, and the driving gear 12 is rotatably installed on the outside of the mounting sleeve 112, and the first driving motor 13 is fixedly installed on one side of the mounting sleeve 112.

[0026] Among them, by setting four support frames 11, two of them form a group installed on the outside of the lamp pole 1, the support frame 11 includes a part wrapped around the outside of the lamp pole 1 and a part extending outward, and the outward extending part is used to support the smart billboard 3. During use, since the outward extending ends of the two support frames 11 that are away from each other are both subjected to the downward force from the smart billboard 3, a bending moment will be generated at the connection between the two support frames 11 wrapped around the outside of the lamp pole 1. This bending moment makes the mutual connection between the two support frames 11 more stable (the bolts on the two connecting rods 16 are subjected to shear force during installation, and the bolts will not move left and right, which can avoid failure of the connection between the bolts and the two connecting rods 16). In addition, since the connection of the connecting rod 16 is located on the side of the support frame 11 away from the rotating connection part 111, it is easier to make the support frame 11 firmly wrapped around the outside of the lamp pole 1.

[0027] Further, if Figure 3 As shown, support plates 14 are fixedly installed on the upper and lower end surfaces of the support frame 11, and guide rails 15 are fixedly installed on both sides of the end surfaces of the upper and lower support plates 14 facing each other, and the upper and lower ends of the smart billboard 3 are provided with sliding grooves 301 for being stuck in the outside of the guide rails 15 and slidingly connected.

[0028] Among them, by arranging support plates 14 on the upper and lower end surfaces of the support frame 11, it is more convenient to support and install the smart billboard 3, and the top and bottom of the smart billboard 3 can also be shielded to reduce corrosion and aging of the smart billboard 3 during use.

[0029] Further, if Figure 4 and Figure 5 As shown, the cleaning assembly 4 includes an installation box 41 fixedly installed between the upper and lower support plates 14, a U-shaped sliding frame 45 is slidably installed inside the installation box 41, the cleaning roller 42 is rotatably installed on the sliding frame 45, and the sliding frame 45 is fixedly installed with a second drive motor 44 for driving the cleaning roller 42 to rotate, and the end face of the installation box 41 facing the smart billboard 3 is provided with a cleaning groove 4101 for one side of the cleaning roller 42 to extend.

[0030] Among them, a U-shaped sliding frame 45 is slidably installed inside the installation box 41, and the cleaning roller 42 is rotatably installed on the sliding frame 45. During use, by controlling the sliding position of the sliding frame 45, the cleaning roller 42 can be controlled to extend or retract from the cleaning groove 4101, so that the smart billboard 3 can be cleaned more flexibly.

[0031] Further, if Figure 6 and Figure 7As shown, the linkage frame 5 includes a linkage plate 51 located on the side of the smart billboard 3, and the linkage plate 51 is close to the smart billboard 3 with its end face facing the smart billboard 3. The linkage plate 51 is located on the side of the installation box 41 close to the smart billboard 3 away from the lamp pole 1. Push rods 52 are fixedly installed at the upper and lower ends of the linkage plate 51, and one end of the push rod 52 extends into the interior of the installation box 41. A guide shaft 53 is fixedly installed on the push rod 52, and a guide inclined groove 4501 for the guide shaft 53 to slide into is provided on the sliding frame 45.

[0032] Among them, by setting a linkage plate 51 on the side of the installation box 41 close to the smart billboard 3 away from the lamp pole 1, when the smart billboard 3 moves from the side of the linkage plate 51 away from the installation box 41 to the other side under the drive gear 12, the smart billboard 3 will drive the linkage plate 51 to move toward the installation box 41, so that the linkage plate 51 drives the push rod 52 to move toward the inside of the installation box 41. At this time, the guide shaft 53 on the push rod 52 will slide inside the guide inclined groove 4501, so that the sliding frame 45 moves in the direction away from the smart billboard 3, and then the cleaning roller 42 moves away from the smart billboard 3. When the smart billboard 3 moves from the side of the linkage plate 51 close to the installation box 41 to the other side under the drive gear 12, the smart billboard 3 will drive the linkage plate 51 to move in the direction away from the installation box 41, so that the cleaning roller 42 on the sliding frame 45 is close to the smart billboard 3. At this time, the second drive motor 44 is turned on, and the display end surface of the smart billboard 3 can be quickly cleaned.

[0033] It should be noted that compared with cleaning back and forth in two directions, cleaning only when the smart billboard 3 is reset can reduce the residue of the cleaning roller 42 on the end surface to be cleaned (just like mopping the floor in one direction), and can complete the cleaning work on the smart billboard 3 more efficiently. In addition, the tangential direction of rotation of the cleaning roller 42 (i.e., counterclockwise rotation) is opposite to the moving direction of the smart billboard 3, and the contact surface between the linkage plate 51 and the smart billboard 3 is concentrated on the outer end surfaces of the mounting frame at the upper and lower ends.

[0034] In addition, in windy weather, by driving the smart billboard 3 to move and eventually making the two smart billboards 3 overlap each other, the cleaning roller 42 can be controlled to be in a position pressed against the smart billboard 3, which can further increase the wind resistance of the smart billboard 3.

[0035] Furthermore, a dust hood 43 for vacuuming the outer side of the cleaning roller 42 is provided on the side of the cleaning roller 42, and the upper and lower ends of the dust hood 43 are fixedly connected to the upper and lower ends of the sliding frame 45 respectively; the outer peripheral surface of the cleaning roller 42 is provided with a plurality of grooves 4201 along the length direction, and the plurality of grooves 4201 are distributed in a circular array, and the top view projection contour of the groove 4201 is an isosceles trapezoidal shape, and the wider side of the groove 4201 is close to the central axis of the cleaning roller 42.

[0036] Among them, by arranging a dust cover 43 on the side of the cleaning roller 42, the dust attached to the cleaning roller 42 can be conveniently absorbed into the inside of the dust cover 43, so that a certain position of the cleaning roller 42 can avoid the dust on the surface from sticking to the smart billboard 3 again when it contacts the smart billboard 3 next time. By setting the groove 4201 to an isosceles trapezoidal shape, the dust on the surface of the smart billboard 3 can be scraped off more easily.

[0037] Furthermore, a partition 46 is fixedly installed inside the dust hood 43, and a dust collecting groove 4601 is provided on the partition 46 at a position facing the groove 4201. A dust collecting space 4301 is formed inside the dust hood 43, and an exhaust fan 431 for extracting the gas inside the dust collecting space 4301 is fixedly installed inside the dust hood 43. The dust collecting groove 4601 facing the groove 4201 can generate suction to absorb the dust inside the groove 4201 into the dust collecting space 4301, so that the outer end surface of the cleaning roller 42 is cleaner.

[0038] Working principle: When the smart billboard 3 moves from one side of the linkage plate 51 away from the installation box 41 to the other side under the drive gear 12, the smart billboard 3 will drive the linkage plate 51 to move toward the installation box 41, so that the linkage plate 51 drives the push rod 52 to move toward the inside of the installation box 41. At this time, the guide shaft 53 on the push rod 52 will slide inside the guide inclined groove 4501, causing the sliding frame 45 to move in the direction away from the smart billboard 3, thereby causing the cleaning roller 42 to move away from the smart billboard 3. At this time, the cleaning roller 42 will not rotate, and the cleaning roller 42 will not contact the smart billboard 3; when the smart billboard 3 moves from the side of the linkage plate 51 close to the installation box 41 to the other side under the drive gear 12, the smart billboard 3 will drive the linkage plate 51 to move in the direction away from the installation box 41, so that the cleaning roller 42 on the sliding frame 45 is close to the smart billboard 3. At this time, the second drive motor 44 is turned on, and the display end surface of the smart billboard 3 can be quickly cleaned.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. 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 various embodiments of the present invention.
