[0036] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 10 , in this embodiment, an advertisement display and playback device includes an advertising machine 1, which includes a machine body 11, a front plate 12 and a back plate 15 respectively connected to both sides of the machine body 11, and an LCD screen 13 is installed on the front plate 12;

[0039] A migration mechanism 2, which includes transmission covers 21 respectively connected to the narrow sides of both sides of the machine body 11. A cleaning member is provided outside the front plate 12 between the two groups of transmission covers 21, and a migration member for adjusting the lifting of the cleaning member is installed on the transmission cover 21;

[0040] A dual-mode energy-saving mechanism 3 is installed on the top of the machine body 11, which includes a photovoltaic panel 32 and a vertical shaft frame 33 provided at the bottom of the photovoltaic panel 32, and wind turbine blades 34 are installed on the vertical shaft frame 33;

[0041] A rain detection mechanism 5 is used to adjust the display screen of the LCD screen 13 after rain detection;

[0042] A support mechanism 6 is installed at the bottom of the machine body 11, and an air inlet duct is provided at the bottom of the machine body 11;

[0043] A heat dissipation mechanism 7 is installed at the bottom of the inner cavity of the machine body 11 and is located at the top of the air inlet duct for heat dissipation and air induction; and

[0044] A transmission mechanism 8 is installed at the top of the inner cavity of the machine body 11 and is provided at the bottom of a group of vertical shaft frames 33 located on the side for driving the lifting member to work;

[0045] With the above solution, the photovoltaic panel 32 on the top of the body 11 converts solar energy into electrical energy, the wind turbine blades 34 on the vertical axis frame 33 are driven by wind force to rotate and convert into electrical energy. The electrical energy is stored or directly supplied for equipment use. The transfer member on the transmission cover 21 receives the power of the transmission mechanism 8 and drives the cleaning member to move up and down along the outside of the front plate 12 to remove dust or rainwater on the screen surface. The rotational power of the side vertical axis frame 33 is transmitted to the transfer member through the transmission mechanism 8, converting part of the mechanical energy of wind power generation into the lifting power of the cleaning mechanism, achieving energy-saving operation. The heat dissipation mechanism 7 sucks in external air from the air inlet duct at the bottom of the body 11. After the air flow dissipates heat from the internal components, it is discharged from the back plate 15, forming a continuous air flow cycle to prevent the equipment from overheating. The design of the air inlet duct ensures that the external air is preliminarily filtered before entering, reducing dust intrusion. The support mechanism 6 maintains the balance of the body 11 through the bottom fixing structure, and the air inlet duct is integrated into the support mechanism, taking into account both function and structural strength;

[0046] The rainfall detection mechanism 5 monitors the rainfall signal in real time. When rainwater is detected, it immediately sends an instruction to the control unit to dynamically adjust the display mode of the LCD screen 13, such as reducing the brightness, enhancing the contrast, or switching to a waterproof screen, ensuring that the picture is clearly visible on rainy days.

[0047] Please refer to Figure 1 and Figure 6 Also included is a protection mechanism 4. The protection mechanism 4 is placed outside the bottom of the body 11 and includes a protection strip 41. The inner wall of the protection strip 41 is connected to the outer wall of the bottom of the body 11 through an adapter block 42. The protection strip 41 can play a protective role and reduce the direct damage to the advertising machine 1 caused by external impacts.

[0048] Please refer to Figure 1 and Figure 8 On the top of the front plate 12, there is a sound hole 14, and on the top of the back plate 15, there is an air outlet hole 151. The air outlet hole 151 is communicated with the inner cavity of the body 11. On the side of the back plate 15 close to the inner cavity of the body 11, a water-retaining inclined plate 154 is connected. The water-retaining inclined plate 154 is placed at the bottom of the air outlet hole 151. Specifically, the water-retaining inclined plate 154 can be inclined at 15°. In case of strong wind and heavy rain weather, if some rainwater enters the air outlet hole 151, the gravity can be used to guide the rainwater to flow down along the outer wall of the back plate 15 through the water-retaining inclined plate 154, preventing it from entering the interior of the body 11.

[0049] Please refer to Figure 2 and Figure 8The dual-mode energy-saving mechanism 3 also includes a support frame 31, which is provided with four groups. The four groups of support frames 31 are connected to the top of the body 11, and the support frames 31 are connected to the bottom of the photovoltaic panel 32 on the side away from the body 11; the vertical axis frames 33 are provided with at least three groups, and the outer wall of each group of the vertical axis frames 33 is connected to three groups of wind blades 34 arranged in a circular array. A generator 35 connected to the output shaft end of the bottom of the vertical axis frame 33 is installed on the top of the inner cavity of the body 11, and the output shaft at the bottom of the vertical axis frame 33 is rotated with the body 11;

[0050] The photovoltaic panels 32 and the vertical axis frame 33 can jointly generate electricity. The photovoltaic panels 32 utilize solar energy, and the wind blades 34 utilize wind energy to drive the vertical axis frame 33 to rotate. The power storage component may include a separate energy source for receiving the photovoltaic panels 32 and the vertical axis frame 33, breaking through the power supply limitations of traditional outdoor equipment.

The control component can be a high-temperature resistant component with an operating temperature of -20°C to +60°C. A temperature sensor is provided therein to alarm for high temperatures. When the temperature is ≥70°C, the brightness is automatically reduced or the device is shut down, and a signal is sent remotely to alarm.

[0052] The two-state trigger switch 153 is electrically connected to the control component;

[0053] When the tipping bucket rain gauge 51 detects rainfall, rainwater flows into the water tank 52 through the rain feeding bucket 53. The float 54 in the water tank rises with the water level, and the guide bar 56 is pushed up along the guide groove 152 through the slide bar 55. One side of the two-state trigger switch 153 contacts the guide bar 56, and the guide bar 56 is blocked, which can trigger the two-state trigger switch 153. After receiving the signal, the control component performs the operation: reducing the brightness of the LCD screen 13 or switching the waterproof display content. When reducing the brightness of the LCD screen 13, a high-contrast waterproof screen can also be switched to ensure visibility in rainy days. The waterproof display content can be "Be careful in rainy days" and so on.

[0055] Specifically, when the transmission rod 27 rotates, it can drive the mounting base 23 that cooperates with its thread to rise and fall. When the mounting base 23 is adjusted up and down, the gear 25 will roll on the rack 26, driving the cleaning roller 24 to rotate, thereby driving the cleaning roller 24 to clean the LCD screen 13, realizing rolling wiping instead of simple scraping, improving cleaning efficiency and reducing wear.

Elastic pressing blocks 98 are connected to the top ends of both ends of the filter frame 91;

[0061] The central shaft 28 of the drive wheel drives the gear A93 to rotate. After being transmitted by the gear A93, the gear B94 and the gear C95, the eccentric shaft 96 drives the floating strip 97 to reciprocate. The floating strip periodically presses and pushes the filter frame 91 through the elastic pressing block 98, and cooperates with the elastic reset of the spring telescopic rod 92 to realize the vibration dust removal of the filter frame 91.

The synchronous belt 86 drives the synchronous wheel B85 to drive the threaded transmission rod 27 to rotate, so that the mounting seat 23 is lifted and lowered along the transmission rod. When the transmission rod 27 rotates, it can drive the mounting seat 23 matched with its thread to rise and fall. When the mounting seat 23 is adjusted up and down, the gear 25 is driven to roll on the rack 26, driving the cleaning roller 24 to rotate, thereby driving the cleaning roller 24 to clean the LCD screen 13, realizing rolling wiping instead of simple scraping, removing dust or rainwater from the screen surface, and converting part of the mechanical energy of wind power generation into the lifting power of the cleaning mechanism, realizing energy saving. Energy-efficient operation, the cooling fan 72 draws air from the bottom air inlet duct, and the air is filtered by the filter frame 91 and flows upward. The air carrying heat can be discharged from the air outlet 151 to prevent the equipment from overheating. The design of the air inlet duct ensures that the external air is preliminarily filtered before entering, reducing dust intrusion. The central shaft 28 of the transmission wheel drives the gear A93 to rotate. After transmission through the gear A93, gear B94 and gear C95, the eccentric shaft 96 drives the floating bar 97 to reciprocate. The floating bar periodically presses the filter frame 91 through the elastic pressing block 98, and cooperates with the elastic reset of the spring telescopic rod 92 to achieve vibration dust removal of the filter frame 91. The support mechanism 6 maintains the balance of the body 11 through the bottom fixed structure. The air inlet duct is integrated into the support mechanism, taking into account both function and structural strength.

[0065] The rainfall detection mechanism 5 monitors the rainfall signal in real time. When rain is detected, it immediately sends instructions to the control unit to dynamically adjust the display mode of the LCD screen 13, such as reducing the brightness, enhancing the contrast or switching to a waterproof screen to ensure that the screen is clearly visible on rainy days.
