Description

Technical Field

[0001] This invention belongs to the field of smart street light technology, specifically a smart street light with a protective structure for the display screen. Background Technology

[0002] Streetlights are closely related to our lives, illuminating the road at night and ensuring people's safe travel. With the advancement of social technology and rapid economic development, smart streetlights have entered people's lives, providing intelligent data for urban development and making important contributions to the construction of smart cities.

[0003] As the atmospheric environment deteriorates, public facilities like streetlights, which are exposed to the elements for extended periods, suffer significant performance degradation due to daily dust accumulation. For instance, some streetlights with built-in display screens have become unusable as they are not cleaned, rendering them merely decorative "decorative objects." To address these technical issues, a smart streetlight with a protective structure for the display screen is proposed. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a smart street light with a protective structure for the display screen. To simplify the structure, reduce costs, and minimize energy consumption, this invention fully utilizes the principle of mechanical system substitution. It proposes a system where three mechanisms—a cleaning and dust removal mechanism, a lifting linkage mechanism, and a smog detection component—cooperate. Through the liquid impact effect, the fluctuations of the liquid and the resistance between the components generate pressure fluctuations and disturbances within the device, replacing the existing lifting mechanical pumping device to clean and remove dust from the display screen, thus reducing power consumption. This effectively solves the technical problem currently prevalent in the market where long-term neglect of cleaning of the display screen leads to functional loss and prevents it from providing convenience to the public.

[0037] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

Therefore, features specified with "first," etc., may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

[0039] In the embodiments of this invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," and "fixation" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection, a direct connection, a welding connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.

[0040] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0041] like Figures 1 to 11As shown, a smart street light with a protective structure for the display screen includes a support column 1 and a display screen body 3. The surface of the support column 1 is provided with an embedded groove 2, and the display screen body 3 is located inside the embedded groove 2. The device also includes a cleaning and dust removal mechanism 32 and a lifting linkage mechanism 33. The cleaning and dust removal mechanism 32 is located in the inner cavity of the support column 1, and the lifting linkage mechanism 33 is located on both sides of the outer wall of the support column 1. The inner cavity of the support column 1 is provided with a partition plate 18, and a haze detection component 34 is provided above the partition plate 18.

[0042] In this embodiment, with the cooperation of the cleaning and dust removal mechanism 32, the lifting linkage mechanism 33, and the haze detection component 34, the liquid impact effect is achieved by using the fluctuation of the liquid and the resistance between the devices to generate pressure fluctuations and disturbances within the device. This replaces the existing lifting mechanical water pumping device, thus completing the cleaning and dust removal of the display screen body 3 and reducing power consumption. This effectively solves the technical problem in the current market where displays are not cleaned for a long time, resulting in functional loss and failure to provide convenience to the public.

[0043] The smog detection component 34 includes a dust collection net 25 and a smog detector 27. The dust collection net 25 is located above the partition plate 18. Four sets of connecting rods 26 are provided on the surface of the dust collection net 25. The smog detector 27 is located on one side of the four sets of connecting rods 26. The smog detector 27 is electrically connected to the electric cylinder 6 through a conductive line. A discharge pipe 22 is provided on one side of the outer wall of the support column 1. A solenoid valve 23 is provided on the outer wall of the discharge pipe 22. One end of the discharge pipe 22 is connected to the interior of the smog detection component 34.

[0044] In this embodiment, when in an environment with severe smog or dust particles, the dust collection net 25 filters particulate matter and dust from the air, adjusting the air freshness around the device. At the same time, the smog detector 27 collects surrounding air samples in a timely manner and uses its built-in sensor technology to detect the concentration and level of smog substances. If the detected concentration and level exceed a certain index, the smog detector 27 will transmit information and control the electric cylinder 6 through the transmission line. The device will automatically open the electric cylinder 6 to facilitate the subsequent work progress of the cleaning and dust removal mechanism 32 and the lifting linkage mechanism 33. Later, if a lot of pollutants or waste liquid accumulates inside the component, the solenoid valve 23 will be opened to control the discharge pipe 22 to discharge unnecessary impurities and maintain the working environment of the smart street light.

[0045] The lifting linkage mechanism 33 includes a fixed plate 5, an electric cylinder 6, a sliding block 8, and an L-shaped connecting rod 11. The fixed plate 5 is located on both sides of the outer wall of the support column 1. The bottom of the inner cavity of the fixed plate 5 is provided with an electric cylinder 6. The telescopic end of the electric cylinder 6 is provided with an electric telescopic rod 7. The top of the electric telescopic rod 7 is provided with a sliding block 8. The outer wall of the sliding block 8 is provided with an L-shaped connecting rod 11. One end of the L-shaped connecting rod 11 is located on the outer wall of the protective cleaning plate 4.

[0046] The top of the sliding block 8 is provided with two sets of damping rods 10, and the other end of the damping rods 10 is located at the top of the inner cavity of the fixed plate 5. The outer walls of the two sets of damping rods 10 are all provided with matching buffer springs 9, and the outer walls of the two fixed plates 5 are all provided with matching protective covers 12.

[0047] In this embodiment, the electric cylinder 6 operates autonomously based on the detection results of the smog detection component 34. The electric cylinder 6 controls the hydraulic or pneumatic system to cause the piston inside the cylinder to extend and retract, thereby driving the electric telescopic rod 7 to rise and fall. The sliding block 8, connected to the electric telescopic rod 7, moves up and down with the extension and retraction of the electric cylinder 6. Consequently, the L-shaped connecting rod 2611, under the operation of the sliding block 8, links with the protective cleaning plate 4 to provide protection and cleaning for the display screen body 3. During multiple lifting processes, the presence of the buffer spring 9 and damping rod 10 is used to control the shock absorption and stability of the sliding block 8 during movement, making the lifting process smoother. The protective cover 12 outside the fixed plate 5 not only enhances the overall aesthetics of the device but also protects the internal components of the lifting linkage mechanism 33 from the influence of the external environment and dust, ensuring the normal operation of the mechanism.

[0048] Based on the lifting linkage mechanism 33 proposed in this embodiment, the distance between the protective cleaning plate 4 and the display screen body 3 is adjusted in a timely manner by controlling the extension and retraction movement of the electric cylinder 6, so as to protect and maintain the normal working state of the display screen body 3. At the same time, the damping rod 10 and the buffer spring 9 can provide stable damping and shock absorption effects, ensuring that the lifting process is smooth and reliable. The protective cover 12 plays the role of protecting the internal components and preventing external dust and other substances from affecting the operation of the mechanism.

[0049] The cleaning and dust removal mechanism 32 includes a protective cleaning plate 4, an L-shaped pressure rod 15, and a squeezing plate 16. The protective cleaning plate 4 is located on the outer wall of the support column 1, the L-shaped pressure rod 15 is located in the inner cavity of the support column 1, and the squeezing plate 16 is located at one end of the L-shaped pressure rod 15.

[0050] The inner cavity of the support column 1 is provided with a water storage tank 14, one end of the L-shaped pressure rod 15 is located on the outer wall of the sliding block 8, the squeezing plate 16 is located in the inner cavity of the water storage tank 14, and an infusion pipe 17 is provided on one side of the water storage tank 14. An auxiliary groove 13 is also provided on the surface of the support column 1, and one end of the infusion pipe 17 passes through the interior of the auxiliary groove 13 and connects to the interior of the protective cleaning plate 4.

[0051] The top of the support column 1 is provided with four sets of L-shaped support pipes 19, the top of the four sets of L-shaped support pipes 19 is provided with a top plate 20, the top surface of the top plate 20 is provided with a filter screen 21, one side of the outer wall of the top plate 20 is provided with a liquid conveying pipe 24, and the other end of the liquid conveying pipe 24 is located in the inner cavity of the water storage tank 14.

[0052] In this embodiment, synchronous operation is carried out inside the support column 1. For example, when the lifting linkage mechanism 33 rises, the L-shaped pressure rod 15 drives the extrusion plate 16 to rise inside the water tank 14. Based on the principle of liquid impact effect, when the extrusion plate 16 passes through the liquid inside the water tank 14, the liquid will exert resistance on it, which will cause pressure fluctuations and disturbances around the liquid, thereby squeezing the liquid into the inside of the infusion tube 17, and working with the protective cleaning plate 4 to clean and remove dust from the display screen body 3.

[0053] The top plate 20 is installed on top of four sets of L-shaped support pipes 19. Its top surface is equipped with a filter screen 21 for filtering particulate matter in the air. A liquid conveying pipe 24 is provided on one side of the outer wall of the top plate 20. The other end of the liquid conveying pipe 24 is connected to the inner cavity of the water storage tank 14. In this way, the cleaning liquid can flow along the support column 1 through the liquid conveying pipe 24 to the inside of the water storage tank 14 for collection. At the same time, the liquid stored inside the water storage tank 14 of this device also includes the cleaning water added daily by sanitation workers.

[0054] The bottom of the four sets of L-shaped support tubes 19 are also connected to the inside of the support column 1, and the collected rainwater is used to clean the dust collection net 25.

[0055] In summary, the display screen is cleaned and dusted through mechanisms such as the protective cleaning plate 4, L-shaped pressure rod 15, squeezing plate 16, water tank 14, infusion pipe 17, L-shaped support pipe 19, and top plate 20. The liquid impact effect effectively cleans and removes dust from the display screen body 3. The water tank 14 and infusion pipe 17 provide storage and delivery channels for the cleaning liquid, while the filter 21 filters airborne particles, enabling the smart street light to achieve efficient display screen cleaning and dust removal.

[0056] Mounting plates 28 are provided on both sides of the bottom surface of the top plate 20. LED lights 29 are provided inside the two mounting plates 28. A solar panel 31 is provided on one side of the outer wall of the top plate 20. The solar panel 31 and the LED lights 29 are electrically connected through conductive lines.

[0057] This smart street light uses LED lighting lamp 29 as the light source. The light-emitting principle of LED lighting lamp 29 is based on the electroluminescence effect of semiconductor materials. When current passes through semiconductor materials, it triggers the recombination of electrons and holes, thereby releasing energy and producing visible light. The advantages of LED lighting lamp 29 are high efficiency and energy saving, long life and high brightness.

[0058] In addition, a solar panel 31 is installed on one side of the outer wall of the top plate 20. The solar panel 31 uses the radiation of sunlight to convert energy. The solar panel 31 adopts the photovoltaic effect. When sunlight shines on the surface, the photon energy is absorbed by the photosensitive material and an electric current is generated. In this way, the solar panel 31 converts solar energy into electrical energy to supply power. In order to transmit electrical energy between the solar panel 31 and the LED lighting lamp 29, a conductive wire is used for electrical control connection to realize energy transmission and control. The function of the conductive wire is to transmit the electrical energy collected by the solar panel 31 to the LED lighting lamp 29 so that it can work normally.

[0059] A control panel 30 is provided on one side of the outer wall of the support column 1. The display screen body 3, solenoid valve 23, LED lighting lamp 29 and solar panel 31 are electrically connected to the control panel 30 through conduction lines.

[0060] The display screen body 3, solenoid valve 23, LED lighting lamp 29 and solar panel 31 used in this device are all mature existing technologies. The working principles of the display screen body 3, solenoid valve 23, LED lighting lamp 29 and solar panel 31 are also well known to those skilled in the art, and will not be described in detail here.

[0061] In practical use, in Example 1, when in an environment with severe smog or dust particles, the dust filter 25 will filter particulate matter and dust in the air, adjusting the air freshness around the device. At the same time, the smog detector 27 will collect surrounding air samples in a timely manner and use its own built-in sensor technology to detect the concentration and level of smog substances. If the detected concentration and level exceed a certain index, the smog detector 27 will transmit information and command control to the electric cylinder 6 through the transmission line, and the device will automatically activate the electric cylinder 6.

[0062] Specifically, the electric cylinder 6 operates autonomously based on the detection results of the smog detection component 34. The electric cylinder 6 drives the electric telescopic rod 7 to rise and fall, and the sliding block 8 moves up and down with the telescopic movement of the electric cylinder 6 through its connection with the electric telescopic rod 7. As a result, the L-shaped connecting rod 2611, under the operation of the sliding block 8, will work in conjunction with the protective cleaning plate 4 to provide protection and cleaning for the display screen body 3.

[0063] Example 2: Based on the above example, when the lifting linkage mechanism 33 rises, the L-shaped pressure rod 15 drives the squeezing plate 16 to rise inside the water tank 14. When the squeezing plate 16 passes through the liquid inside the water tank 14, the liquid will exert resistance on it, which will cause pressure fluctuations and disturbances around the liquid, thereby squeezing the liquid into the inside of the infusion tube 17, and working with the protective cleaning plate 4 to clean and remove dust from the display screen body 3.

[0064] Specifically, the top plate 20 is installed on top of four sets of L-shaped support pipes 19, and its top surface is provided with a filter screen 21 for filtering particulate matter in the air. A liquid conveying pipe 24 is provided on one side of the outer wall of the top plate 20, and the other end of the liquid conveying pipe 24 is connected to the inner cavity of the water storage tank 14. In this way, the cleaning liquid can flow along the support column 1 through the liquid conveying pipe 24 to the inside of the water storage tank 14 for collection. At the same time, the liquid stored inside the water storage tank 14 of this device is also collected.
