Description

Technical Field

[0001] The invention belongs to the technical field of advertising, and in particular relates to a multifunctional portable light pole and light box. Background Art

[0002] Street light box: a device that combines the functions of a street light and a light box. It is usually installed on a light pole to realize multiple functions such as lighting, advertising display or information release. The light box part generally has a transparent or translucent display surface, and lighting fixtures are installed inside to make the display content more eye-catching under the reflection of the light.

[0003] Light box advertising surfaces: They are usually made of materials such as plastic or glass. However, when these materials rub against air or are exposed to light, static electricity is easily generated. Dust particles themselves carry a certain charge. When charged dust particles approach the static-charged light box advertising surface, they gradually settle on the light box advertising surface under the action of static electricity. This is especially true for street light boxes near pollution sources such as factories, construction sites, or roadsides. Solid particles carried by factory exhaust, dust generated by construction activities at construction sites, and the interaction between people, vehicles, and air, all accumulate on the street light box advertising surface under the action of air flow.

[0004] At the same time, during precipitation, some dust is washed away from the advertising surface of street lamp light boxes by rainwater. However, after precipitation, as the water evaporates, dust in the air is more likely to adhere to the damp advertising surface of street lamp light boxes. That is, when the advertising surface has a certain humidity, the liquid film between the dust particles and the advertising surface generates surface tension, which increases the rate of dust adhesion to the advertising surface. In addition, there are certain impurities in rainwater, such as soil particles or industrial pollutants. After the rainwater evaporates, some of the aforementioned impurities will remain on the advertising surface.

[0005] In addition, there are certain chemical elements in the air. When there is a certain humidity on the advertising surface, the metabolic products of microorganisms such as mold or algae interact with the air, and chemical reactions occur, which in turn produce difficult-to-remove compounds that are deposited on the advertising surface. In the long run, this will not only change the physical properties of the advertising surface, but also affect the lighting and publicity effects of the street light box. Summary of the Invention

[0041] The method for cleaning stubborn stains on the advertising surface of street light boxes is to use the above-mentioned multifunctional portable light pole light box for cleaning. The specific steps are as follows:

[0042] S1: First, the stand and the vertical rail work together to control the wing plate to drive the Z-shaped plate to reciprocate. After that, the roller brush first contacts the advertising screen and softens the stubborn stains deposited on the end surface of the advertising screen through the rolling of the roller brush. In specific implementation, the roller brush can be driven to rotate by an external motor, and then the relative movement between the grid plate in a static state and the roller brush in a moving state can remove the solid particles in the gaps between the bristles of the roller brush, thereby avoiding secondary damage to the advertising screen caused by solid particles.

[0043] S2: The Z-shaped plate then drives the corner frame to reciprocate synchronously. During this process, the double-headed shovel is used to scrape away the stains deposited on the end surface of the advertising screen. The elastic potential energy of the compressed spring is used to enhance the interaction force between the double-headed shovel and the advertising screen, which helps to improve the scraping and cleaning effect. At the same time, it can effectively avoid excessive rigid contact between the double-headed shovel and stubborn stains, thereby extending the service life of the advertising screen.

[0044] S3: Finally, through the meshing action between the gear ring and the unilateral rack, the gear ring is prompted to rotate in the forward direction. Through the engagement between its inner tooth groove and the pawl, the cross bar is synchronously driven to rotate a certain angle through the workpiece disc, and then the cam squeezes the telescopic column a certain distance, thereby increasing the compression amount of the compression spring, thereby gradually improving the interaction force between the double-headed shovel and the advertising screen, and further improving the scraping and cleaning ability of the double-headed shovel.

[0045] The present invention has the following beneficial effects:

[0046] 1. The present invention controls the stand through the vertical rail and synchronously drives the wing plate to reciprocate. During this process, the stains deposited on the end face of the advertising screen are softened by the roller brush. Then, the advertising surface softened by the roller brush is scraped and cleaned through the relative movement between the double-headed shovel and the advertising surface, thereby fully ensuring the cleanliness of the end face of the advertising screen and reducing the probability of chemical reaction between microbial metabolites or other metal particles on the end face of the advertising screen and acidic or alkaline substances in the air, that is, reducing the degree of corrosion of the advertising screen material by stains and increasing the service life of the advertising screen. At the same time, through the periodic scraping of the double-headed shovel, the coverage area of ​​stubborn stains is reduced, and the dust deposition phenomenon on the end face of the advertising screen is fully reduced, thereby ensuring the lighting effect and publicity effect of the advertising screen.

[0047] 2. The present invention realizes that the ring gear that reciprocates synchronously with the cross bar and meshes with the unilateral rack each time, so that the ring gear drives the cross bar to rotate unidirectionally a specified angle through the engagement between its inner tooth groove and the pawl during each reciprocating motion, and then realizes that when the ring gear and the unilateral rack act, the cam synchronously squeezes the telescopic column a certain distance, thereby increasing the deformation of the compression spring, gradually strengthening the interaction force between the double-headed shovel and the advertising screen, and graded scraping and cleaning of stubborn stains deposited on the end face of the advertising screen without damaging the advertising screen, which helps to increase the service life of the advertising screen.

[0048] 3. The present invention continuously generates mutual motion with the side gear during the synchronous movement of the side rack and the vertical rail. In this process, the rotation of the side gear is converted into the rotation of the worm through the meshing action of the worm wheel and the worm that move coaxially with the side gear. The rotation of the position column is controlled by the mutual meshing of the sprockets. Finally, the relative motion relationship between the ball bar and the snake mouth groove is used to prompt the side holder to control the wedge plate to push the base toward the light box until the brim cap completely covers the dust barrier plate, thereby realizing partition protection for the working ends of the double-headed shovel and the roller brush, improving the service life of the roller brush and the double-headed shovel, avoiding pollution caused by the external environment, improving the cleanliness of the contact between the roller brush and the double-headed shovel and the advertising surface, and thereby improving the cleaning effect of the roller brush and the double-headed shovel on the advertising screen.

[0070] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0071] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0072] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0073] Reference Figure 1 、 Figure 2 and Figure 3 It can be seen that a multifunctional portable light pole light box 1 includes a light box 1, a control unit 2 is symmetrically arranged on the outer wall of the light box 1, a storage unit 3 is arranged at each of the four corners of the end face of one side of the light box 1, and a cleaning unit 4 is arranged on one side of the storage unit 3;

[0074] Reference Figure 1 、 Figure 2 and Figure 3It can be seen that the end face of the light box 1 close to the water storage cylinder 43 is symmetrically snap-fitted with a mesh 11 connected to the inside of the light box 1, and the middle position of the end face of the mesh 11 away from the unilateral rack 425 is snap-fitted with a photovoltaic panel 12, and the photovoltaic panel 12 is inclined at an angle of sixty degrees to the ground. The outer wall of the light box 1 is symmetrically snap-fitted with a wall panel 13, and the end face of the wall panel 13 away from the light box 1 is snap-fitted with a casting chamber 14 connected to the inside of the light box 1. The outer wall of the light box 1 away from the water storage cylinder 43 is snap-fitted with a water-saving plate 15, and the water-saving plate 15 is snap-fitted with the unilateral rack 425. The four outer corners of the light box 1 are all slidably snap-fitted with side rails 16, and the side rails 16 are slidably snap-fitted with the Z-shaped plate 41. Two of the outer walls of the light box 1 are symmetrically snap-fitted with advertising screens 17, and the advertising screens 17 are vertically distributed with the wall panels 13.

[0075] Auxiliary function of light box 1:

[0076] Store rainwater and regularly irrigate the surrounding green belts:

[0077] Specific watering process:

[0078] First, the water-saving plate 15 cooperates with the light box 1 to collect rainwater. In practice, there is a certain gap between the water-saving plate 15 and the outer wall of the light box 1, thereby forming a groove-like water container. The height of the water-saving plate 15 is the highest water level that can be stored inside the light box 1. When it rains, the falling rainwater, under the action of gravity, passes through the outer wall of the light box 1 and gathers in the aforementioned groove-like area, and then flows into the designated area inside the light box 1.

[0079] Next, the clean water stored in the water pump built into the light box 1 is directed to the interior of the casting chamber 14 through the water pump (not shown in the figure, and in a specific implementation, a filtering device can be added to the rainwater flow pipe inside the light box 1 to reduce impurities in the rainwater. On the one hand, this reduces the clogging of the casting chamber 14 caused by impurities in the rainwater; on the other hand, it reduces the secondary damage to the advertising screen 17 when the rainwater is reused, which helps to increase the service life of the advertising screen 17). In a specific implementation, a connecting hose can be added inside the light box 1 to connect the rainwater in the light box 1 and the casting chamber 14.

[0080] Finally, pouring is carried out toward the surrounding green belt through the pouring chamber 14, and the pouring chamber 14 is a porous pouring nozzle, which can effectively spray the rainwater in the light box 1 toward the surrounding green belt, further ensuring the healthy growth of green belt, making full use of water resources (especially for water-scarce areas), regulating the climate, beautifying the environment, and strengthening the adsorption and interception of dust or other solid particles in the air by green belt, indirectly reducing the accumulation of dust and other impurities on the end surface of the advertising screen 17 of the light box 1, thereby improving the lighting effect and publicity effect of the advertising screen 17;

[0081] Auxiliary function 2 of light box 1:

[0082] Emergency Power Self-Sufficiency:

[0083] Through the photovoltaic effect of the photovoltaic panel 12 in a state of sufficient sunlight (the photovoltaic effect refers to when light shines on certain semiconductor materials, the energy of photons is absorbed by the semiconductor, so that the electrons inside the semiconductor gain enough energy to jump from the valence band to the conduction band, generating electron-hole pairs. Finally, with the help of the electrode structure inside the photovoltaic panel 12, the separated electrons and holes are collected at the two ends of the battery respectively), the solar energy is continuously converted into standby electrical energy. In this way, when there is a sudden power outage, the street lamp box 1 can still effectively illuminate the city or designated area, thereby improving people's sense of security;

[0084] In addition, the photovoltaic panels 12 are tilted for the following purposes: they can effectively guide rainwater, reduce the precipitation of rainwater on the end surface of the photovoltaic panels 12, and improve the power generation efficiency of the photovoltaic panels 12; at the same time, they can provide certain protection for the photovoltaic panels 12 and reduce the damage to the photovoltaic panels 12 caused by uncertain factors in the external environment;

[0085] The mesh 11 can effectively guide rainwater to a designated area inside the light box 1 (in practice, the rainwater collection area inside the light box 1 is isolated from the internal electronic components). It can also filter some impurities in the rainwater, reducing the number of relatively large objects (larger than the aperture of the mesh 11) that enter the light box 1.

[0086] Side rails 16: The side rails 16 set at the side increase the stability of the Z-shaped plate 41 during movement, indirectly improving the scraping and cleaning accuracy of the cleaning unit 4 on the advertising screen 17, reducing the impact damage to the advertising screen 17 caused by nonlinear vibration, and increasing the service life of the advertising screen 17.

[0095] Then, the wing plate 231 is controlled to synchronously follow the stand 23 under the synchronous action of the stand 23 to perform reciprocating motion;

[0096] Finally, when the side rack 29 is about to engage with the side gear 32, the external electric slider controls the vertical rail 22 again, guided by the T-surface groove 21, to drive the cleaning unit 4 to move away from the brim cap 31 until the vertical rail 22 moves to the initial position.

[0097] The specific cleaning process of the cleaning unit 4 on the advertising screen 17 (in specific implementation, the roller brush 49 in the initial state is tangent to the advertising screen 17, or the roller brush 49 covers the advertising screen 17 for a distance in its radial direction):

[0098] First, as the Z-shaped plate 41 moves in a single motion, the decorative plate 46 synchronously controls the movement of the roller brush 49, generating relative motion with the advertising screen 17. During this process, rainwater stored inside the light box 1 (which has been filtered and is now in a clean water state) is directed to the spray pipe 417 via the water storage cylinder 43 (in a specific implementation, an external hose can be used to connect the rainwater storage area inside the light box 1 and the water storage cylinder 43). The clean water is then directed to the water storage cylinder 43 via an internal water pump, which contains a special detergent concentrate.

[0099] In addition, the detergent liquid in the water storage cylinder 43 can be regularly added through an external adding device, and finally the mixed cleaning liquid is sprayed onto the outer wall of the drum and the end face of the advertising screen 17 in an orderly manner through the spray pipe 417;

[0100] Next, the roller brush 49 mixed with the cleaning liquid (in specific implementation, the bristles on the outer wall of the roller brush 49 are distributed in a gradient manner along its circumference, and the density of the bristles is targeted to enhance the tolerance of the roller brush 49 to different solid particles on the end face of the advertising screen 17, which helps to improve the softening effect of the roller brush 49 on the end face of the advertising screen 17) continuously moves relative to the advertising surface (and the roller brush 49 moves and rotates at the same time, and the rotation can be driven by the built-in motor to rotate the roller brush 49), thereby achieving the softening effect of the roller brush 49 on the end face of the advertising screen 17;

[0101] During this process, the grid plate 48 tangentially distributed with the roller brush 49 (the purpose of chamfering the working end of the grid plate 48 is to reduce the contact area between the grid plate 48 and the roller brush 49 and improve the combing effect of the grid plate 48 on the roller brush 49) continuously moves relative to the roller brush 49 in the moving state, and the solid particles wrapped in the bristles of the roller brush 49 are scraped out through the grid plate 48, so as to ensure the cleanliness of the working end of the roller brush 49 on the advertising screen 17 every time, reduce the secondary damage of the advertising screen 17 to the solid particles between the bristles of the roller brush 49, and improve the service life of the advertising screen 17;

[0102] Finally, by aligning the movement of the corner frame 411 with the Z-shaped plate 41, the corner frame 411 is prompted to synchronously control the corner column 412, driving the double-headed shovel 413 and the advertising screen 17 to move relative to each other. The compression spring 415 changes the rigid contact between the traditional scraper and the working surface, that is, the compression spring 415 contacts the double-headed shovel 413 with a degree of freedom (in a single direction). On the one hand, the interaction force between the double-headed shovel 413 and the advertising screen 17 can be effectively ensured to ensure its scraping effect, while reducing the "breakage" phenomenon between the working end of the double-headed shovel 413 and the end surface of the advertising screen 17 with stubborn stains, thereby increasing the service life of the advertising screen 17.

[0103] The process of adjusting the interaction force between the double-headed shovel 413 and the advertising screen 17 (or the process of changing the deformation of the compression spring 415):

[0104] During the single movement of the cleaning unit 4 following the stand 23 synchronously:

[0105] Take the case where the stand 23 moves from the brim cap 31 end to the water-saving plate 15 end as an example:

[0106] Under the control of the crossbar 44, the gear ring 422 gradually moves toward the water-saving plate 15 until the gear ring 422 and the single-sided rack 425 are meshed to a certain extent. After that, when the gear ring 422 rotates, the inner tooth groove of the gear ring 422 engages with the pawl 424, thereby synchronously driving the work plate 423 to rotate, and then the crossbar 44 drives the cam 45 to rotate a specified angle or number of turns.

[0107] Finally, during its rotation, the cam 45 and the telescopic column 416 move relative to each other, squeezing the telescopic column 416 to move a certain distance toward the advertising screen 17. (At this time, the straight plate 414, under the squeezing action of the telescopic column 416, causes the compression spring 415 to compress by a specified amount, thereby changing the elastic potential energy of the compression spring 415 between the double-headed shovel 413 and the straight plate 414. This gradually adjusts the interaction force between the double-headed shovel 413 and the advertising screen 17, and gradually removes stubborn stains deposited on the end surface of the advertising screen 17 without damaging the advertising screen 17, thereby helping to increase the service life of the advertising screen 17.)

[0108] It is hereby explained that when the ring gear 422 moves from the end of the eave cap 31 to the end of the water-saving plate 15, the meshing between the ring gear 422 and the unilateral rack 425 is in the positive direction (and at this time, the work plate 423 rotates synchronously with the ring gear 422). Therefore, when the ring gear 422 moves from the end of the water-saving plate 15 to the end of the eave cap 31, the meshing between the ring gear 422 and the unilateral rack 425 is in the reverse direction. At this time, the ring gear 422 rotates while the work plate 423 does not rotate, thereby achieving unidirectional rotation of the cam 45 when the ring gear 422 is in positive meshing with the unilateral rack 425, thereby achieving a gradual change in the degree of compression between the cam 45 and the telescopic column 416.

[0109] The rail 233, the horizontal axis 234 and the telescopic spring 235: The rail 233 and the horizontal axis 234 strengthen the movement stability of the Z-shaped plate 41, while the telescopic spring 235 reduces external impact, further improving the operation stability.

In addition, the wheel is coaxial with the side gear 32. Installation; the dividing column 35 is set in the space on the side of the worm 34 away from the side gear 32, and the dividing column 35 is rotatably installed with the brim cap 31; the snake mouth groove 36 is opened on the outer wall of the dividing column 35; the sprocket 37 is clamped and installed on the outer wall of the worm 34 and the dividing column 35 near the photovoltaic panel 12, and the two sprockets 37 are meshed with each other; the spacer 38 is set in the space on the side of the dividing column 35 away from the worm 34, and the spacer 38 is clamped and installed with the brim cap 31;

[0111] Reference Figure 1 、 Figure 4 、 Figure 11 and Figure 12 It can be seen that the end surface of the intermediate plate 38 close to the dividing column 35 is slidably engaged with a side clamping seat 381, the end surface of the side clamping seat 381 close to the dividing column 35 is engaged with a bracket 382, ​​the end surface of the bracket 382 away from the side clamping seat 381 is engaged with a ball rod 383 that cooperates with the snake mouth groove 36, the end surface of the side clamping seat 381 away from the bracket 382 is engaged with a mouth frame 384, the horizontal section of the mouth frame 384 is symmetrically slidably engaged with a spring rod 385, the two spring rods 385 are jointly engaged with a wedge plate 386 at one end away from the mouth frame 384, and the end of the wedge plate 386 away from the side clamping seat 381 is plug-inly mounted with a base 387 that is engaged with the Z-shaped plate 41;

[0112] Reference Figure 4 and Figure 5 It can be seen that the side panels 24 are symmetrically snap-fitted onto the outer wall of the upright seat 23; the double-ear seat 25 is snap-fitted onto the middle position of the side panel 24 away from the Z-shaped panel 41; the vertical rod 26 is slidably snap-fitted onto the middle position of the double-ear seat 25; the return spring 27 is sleeved onto the outer wall of the vertical rod 26; the angle plate 28 is symmetrically snap-fitted onto the outer wall of the vertical rail 22, and the angle plate 28 is directly opposite to the T-surface groove 21; the side rack 29 is snap-fitted onto the middle position of the horizontal section of the angle plate 28;.

[0113] Storage unit 3 provides protection for cleaning unit 4 by separating the storage unit 3 and cleaning unit 4:

[0114] It is hereby explained that when the vertical rail 22 controls the movement of the cleaning unit 4, when the side rack 29 is about to engage with the side gear 32, the movement direction of the vertical rail 22 is changed;

[0115] When the cleaning unit 4 finishes scraping off the stains on the end surface of the advertising screen 17:

[0116] The edge rack 29 moves toward the edge gear 32 under the control of the vertical rail 22 until the intermediate plate 38 contacts the Z-shaped plate 41 (the vertical distance between the intermediate plate 38 and the light box 1 is greater than the vertical distance between the end surface of the Z-shaped plate 41 close to the eave cap 31 and the end surface of the dust blocking plate 42 away from the eave cap 31);

[0117] During this process, the worm wheel 33 is continuously meshed with the worm 34 under the synchronous action of the side gear 32. Thereafter, the side rack 29 is meshed with the side gear 32 through the mutual meshing action of the sprockets 37. The snake mouth groove 36 in the outer wall of the dividing column 35 is synchronously interacted with the ball rod 383, and the side clamping seat 381 is moved through the auxiliary guide of the intermediate plate 38. At the same time, the side clamping seat 381 is engaged with the base 387. That is, the base 387 pulls the Z-shaped plate 41 to move toward the inside of the brim cap 31 during the movement of the side clamping seat 381 until the horizontal section of the brim cap 31 completes the covering of the dust blocking plate 42.

[0118] The engagement process between the wedge plate 386 and the base 387:

[0119] When the side rack 29 is meshed with the side gear 32, the wedge plate 386 is exactly engaged with the base 387 (in the initial state, the side clamping seat 381 and the base 387 are in a positive distribution). When the vertical rail 22 continues to control the side rack 29 to move toward the side gear 32, due to the interference between the Z-shaped plate 41 and the intermediate plate 38, the Z-shaped plate 41 gradually compresses the return spring 27 under the guidance of the side plate 24 (the vertical rod 26 further supports and guides the movement of the Z-shaped plate 41, improving its movement stability) until the side rack 29 is completely meshed with the side gear 32.

[0120] Spring rod 385: further releases the engagement freedom between wedge plate 386 and base 387, reduces overly rigid contact, and reduces the probability of damage due to rigid impact.

[0121] The working principle of the multifunctional portable lamp pole light box 1 provided by the present invention is as follows: Step 1: First, the wing plate 231 is controlled to drive the Z-shaped plate 41 to reciprocate under the coordinated action of the vertical rail 22 through the stand 23. After that, the roller brush 49 first contacts the advertising screen 17, and the stubborn stains deposited on the end surface of the advertising screen 17 are softened by the rolling of the roller brush 49. In specific implementation, the roller brush 49 can be driven to rotate by an external motor, and then the solid particles existing in the gaps between the bristles of the roller brush 49 are removed through the relative movement between the grid plate 48 in a stationary state and the roller brush 49 in a moving state, thereby avoiding secondary damage to the advertising screen 17 by the solid particles;

[0122] Step 2: Then, the Z-shaped plate 41 synchronously drives the corner frame 411 to reciprocate. During this process, the stains deposited on the end surface of the advertising screen 17 are scraped off by the double-headed shovel 413. The elastic potential energy of the compression spring 415 is used to enhance the interaction force between the double-headed shovel 413 and the advertising screen 17, which helps to improve its scraping and cleaning effect. At the same time, it can effectively avoid excessive rigid contact between the double-headed shovel 413 and stubborn stains, thereby increasing the service life of the advertising screen 17.

[0123] Step 3: Finally, through the meshing action between the ring gear 422 and the unilateral rack 425, the ring gear 422 is prompted to rotate forward. Through the engagement between its inner tooth groove and the pawl 424, the cross bar 44 is synchronously driven to rotate a certain angle through the workpiece plate 423, and then the cam 45 squeezes the telescopic column 416 a certain distance, thereby increasing the compression amount of the compression spring 415, and then gradually improving the interaction force between the double-headed shovel 413 and the advertising screen 17, further improving the scraping and cleaning ability of the double-headed shovel 413.
