Description

Intelligent real-time automatic wind-sheltering billboard

Technical Field

The invention relates to a billboard, in particular to a billboard capable of automatically sheltering from wind in real time. The billboard comprises: the billboard comprises a billboard beside a highway, a billboard on a city high building, a billboard on the top of a power or communication tower or on a tower body, a billboard on a building and all billboards which can generate harm to a billboard body and a supporting structure thereof due to wind flowing and wind flowing at the installation position of the billboard.

Background

The billboard can be seen everywhere, and the billboard can be arranged in a place where people move. To highlight the advertising effect of the billboard, the billboard is often mounted at a height that is easy to observe. The size of the billboard determines the weight of the billboard itself. And advertising effects generally desire the larger the billboard size the better.

However, since the billboard is generally located at a high position, when the wind speed is high, the billboard generates a transverse thrust on the billboard body and a structure for supporting the billboard due to the area of the billboard itself, thereby generating a potential safety hazard on the billboard and the supporting structure. To secure the billboard and its support structure, the support structure is often made large and strong, which results in an increase in the overall weight and cost of the billboard and support structure. In some cases, the overall weight cannot be increased: like a billboard on a roof, the weight that the roof can carry is limited because the structure of the roof cannot be changed.

Therefore, the safety hazard caused by the thrust of wind on the billboard has the following consequences:

1) the size of the billboard is sacrificed, so that the advertising effect is sacrificed;

2) an increase in overall weight;

3) the reinforcing of the billboard and the supporting structure leads to the increase of the overall cost and the increase of the installation difficulty;

4) certain installation occasions can not solve the problem by reinforcing the whole structure and increasing the whole weight.

To solve these problems, an intelligent billboard structure is the key to solve the problems.

Disclosure of Invention

The technical scheme adopted by the patent for solving the technical problem is as follows: the utility model provides a real-time automatic bill-board of keeping away wind of intelligence, includes the bill-board frame, the show curtain, curtain drive assembly, show curtain roller bearing, the show blade, blade drive assembly, wind sensor, wind direction sensor, vibrations sensor, photosensitive sensor and bill-board controller.

The intelligent real-time automatic wind-sheltering billboard has two display schemes: a shows the curtain scheme, and B shows the blade scheme. The display curtain is arranged in the billboard frame, and the curtain driving component is arranged on the billboard frame and rolls the display curtain up and down or horizontally through the display curtain rolling shaft to form a display curtain scheme A; the display blade is arranged on the billboard frame through the blade driving component and is vertically or horizontally arranged to form a scheme of the display blade B; the billboard controller is mounted on the billboard frame.

According to the intelligent real-time automatic wind-sheltering billboard, the A display curtain scheme hollows out the display curtain by rolling up the curtain when wind power exceeds a safety range, so that the windward side is reduced. The B show blade scheme reduces the windward side by rotating the windward angle of the show blade when the wind power exceeds a safety range.

According to the intelligent real-time automatic wind-sheltering billboard, the blade driving assembly consists of the blade rotating shaft, the motor and the transmission, the electromagnetic clutch, the blade position sensor and the blade bearing. The blade drive assembly is mounted on the billboard frame.

The electromagnetic clutch is coupled when electrified and is separated when the power is lost. In the coupling state, the motor can drive the display blade, and in the disengagement state, the display blade can passively and freely rotate around the self blade rotating shaft. When the electromagnetic clutch is in power failure, the electromagnetic clutch automatically separates the motor, the speed changer and the blade rotating shaft by means of gravity no matter whether the power failure is controlled or the power failure is supplied to the commercial power.

In the above-mentioned scheme of the display blade B, the display blade is driven by a motor and a transmission to jointly drive all or a plurality of blade rotating shafts, a synchronous pulley is mounted on the blade rotating shaft of each display blade, and each display blade is connected with the adjacent display blade by a synchronous belt to form a joint driving mode; or one motor and a speed changer drive one blade rotating shaft independently to form an independent driving mode.

The above-mentioned scheme B shows a blade scheme, in which the windward angle of the rotating display blade is driven by the motor and the transmission, and the direction of the wind is determined according to the feedback of the wind direction sensor, so as to display the bladeMaking automatic rotation adjustment to minimize the windward side of the display blade (7). Or the windward angle of the rotary display blade is that the motor, the speed changer and the blade rotating shaft are separated through the electromagnetic clutch, so that the display blade freely rotates passively under the action of wind force, and the windward side of the display blade is automatically adjusted to the minimum.

In the intelligent real-time automatic wind-sheltering billboard, the display curtain is made of a material which can be rolled and contracted, such as cloth, a chemical fiber film and the like; the size of the curtain is not larger than the size of the billboard frame.

In the intelligent real-time automatic wind-sheltering billboard, the curtain driving component consists of a motor and a winding wheel; the driving component is arranged on the billboard frame.

According to the intelligent real-time automatic wind-sheltering billboard, the display blades are made of aluminum alloy or fiber sheets, and each blade is vertically or horizontally arranged; the cross section of the display blade is streamline, blade rotating shafts are arranged at two ends of the display blade, the blade rotating shafts are asymmetric in front and back of the display blade and are close to the front end of the display blade, and the blade rotating shafts are arranged on a billboard frame.

The intelligent real-time automatic wind-sheltering billboard comprises a wind sensor, a wind direction sensor, a vibration sensor and a photosensitive sensor, wherein the wind sensor, the wind direction sensor, the vibration sensor and the photosensitive sensor are arranged on a billboard frame and are connected with a billboard controller. The billboard controller receives the feedback of the wind sensor, the wind direction sensor and the vibration sensor, calculates the wind power according to the signals of the wind sensor and the wind direction sensor, and folds or adjusts the windward angle of the billboard according to the vibration measured by the vibration sensor; the feedback from the light sensor can be used to limit the switching of the billboard contents or turn on the lights at night.

According to the intelligent real-time automatic wind-sheltering billboard, the billboard controller is composed of the single chip microcomputer. The functions are as follows: wind power, wind direction and vibration are monitored in real time. When the wind power is in a safe range, the curtain is rolled or the display blade is rotated to switch the advertisement content; when the wind power exceeds the safety range, the display curtain is folded to ensure that the curtain part is hollowed out, or the display blade is rotated to ensure that the windward angle of the display blade is minimum. The billboard controller comprises the following functional units: the system comprises a power supply, a sensor input, a motor drive, an electromagnetic clutch drive, an MCU, a communication unit and an LED display.

The beneficial effect of this patent is: the billboard controller measures wind speed, wind direction and vibration in real time, and when the measured value exceeds a safety range, the windward display area of the billboard is changed to be the minimum through the A display curtain scheme and the B display blade scheme. The A display curtain scheme can reduce the area to zero, and the B display blade scheme can not reduce the windward side to zero, but can complete the minimization of the windward side in a short time. Particularly, the passive free rotation function in the scheme B can ensure that the windward side is minimized under the condition that the whole billboard system loses power, and the response speed is the fastest in all the schemes.

When wind speed was in safe safety range, the bill-board had kept the show function of ordinary bill-board through A show curtain scheme and B show blade scheme: switching a plurality of advertisement contents.

By the patent technology, the billboard can be installed on the structure which cannot be installed in the prior art. Larger billboards have previously been possible with constructions that have only been able to mount relatively small area billboards. Many places where the billboard cannot be installed due to large wind speed or rapid change of wind speed have the possibility of installing the billboard. Also, the weight of the billboard is lighter than that of a general billboard.

In the figure: 1. the technical scheme includes that the advertising board comprises a billboard frame, 2 a display screen, 3 a screen driving assembly, 4 a display blade, 5 a blade rotating shaft, 6 a motor and a speed changer, 7 an electromagnetic clutch, 8 a blade position sensor, 9 a blade bearing, 10 a wind sensor, 11 a wind direction sensor, 12 a vibration sensor, 13 a photosensitive sensor, 14 a billboard controller, 15 a power supply, 16 a sensor input, 17 a motor drive, 18 an electromagnetic clutch drive, 19 an MCU, 20 a communication unit, 21 an LED display, 22 a synchronous belt pulley, 23 a synchronous belt, 24 a blade driving assembly and 25 a display screen roller.

Detailed Description

An implementation of the curtain scheme is shown as a in fig. 1. The advertisement display part is composed of an upper display curtain roller 25, a lower display curtain roller 25 and a display curtain 2 (or a left display curtain roller 25 and a right display curtain roller 25). The upper display screen roller 25 is driven to rotate by the screen driving unit 3, and the screen driving unit 3 can rotate forward or backward to change the content of the advertisement display portion. The advertisement display part changes the contents at a time interval set in advance.

In fig. 3, when the wind sensor 10 and the wind sensor 11 detect that the wind force on the windward side is greater than the preset value, the upper display screen roller 25 rotates to retract the display screen 2, so that the area of the display screen 2 in the billboard frame 1 is hollowed out, and the windward side is retracted to the minimum, thereby playing a role in protecting the billboard and supporting the structure of the billboard. When the wind power is restored to the safe range, the display screen roller 25 releases the display screen 2 to restore the advertisement function.

B as shown in fig. 2 shows a blade embodiment implementation. This is accomplished by showing the blades 4. The entire advertising area is divided into several display leaves 4. Under normal conditions, the wind power is in a safe range, each display blade 4 is displayed on the front side (0 degrees) or the back side (180 degrees), and all the display blades 4 are assembled to form a finished advertisement picture, as shown in fig. 2.

When the wind force exceeds the safety range, as shown in fig. 4, the display blades 4 start to rotate so that the windward side of each display blade is minimized, thereby functioning to protect the billboard and support the structure of the billboard. When the wind power is restored to the safe range, the display blade 4 rotates to the 0-degree or 180-degree position, and the advertising function is restored.

As explained above, when the wind force exceeds the safety range, the function of the display blade 4 rotating to keep the windward side to the minimum is achieved by two methods:

the first method is as follows: when the wind power exceeds the safety range, the direction of the wind is determined according to the feedback of the wind direction sensor 11, and the windward angle of the display blade 4 is adjusted, so that the windward side of the whole display blade 4 is minimum. In this way, it is shown that the blade 4 is directly driven in rotation by the motor + transmission 6 via the blade rotation shaft 5. The rotation of the blade rotation shaft 5 is automatic rotation.

The second method is as follows: when the wind power exceeds the safe range, the connection between the motor and the speed changer 6 and the blade rotating shaft 5 is separated through the electromagnetic clutch 7, so that the display blade 4 is driven by the wind power to rotate freely. As shown in fig. 5, since the section showing the blade 4 is a streamline structure and an asymmetric arrangement of the blade rotation axis 5, the end result is: the display blade 4 freely rotates passively under the action of wind force, so that the windward side is the smallest. In this case, the windward side of each display blade 4 can be kept to a minimum. The rotation of the blade rotation shaft 5 is passive free rotation.

The first method differs from the second method in whether the motor + transmission 6 and the blade rotation shaft 5 are engaged in direct drive (without the electromagnetic clutch 7 in between) or in drive via the electromagnetic clutch 7. The first method is to use the detection of the wind direction sensor 11 when adjusting the angle of attack. While the second method may not rely on detection by the wind direction sensor 11. The second method has the advantages that: the billboard can maintain a minimum windward side even when the billboard loses power.

As described above, the motor + transmission 6 may drive the blade rotation shaft 5 in two ways: one motor + transmission 6 drives the blade rotation shafts 5 individually (individually driven), and one motor + transmission 6 drives all the blade rotation shafts 5 (collectively driven).

As shown in fig. 7, a timing pulley 22 is mounted on the blade rotating shaft 5 of each display blade 4, and each display blade 4 is connected to the adjacent display blade 4 by a timing belt 23. In this connection, all the display blades 4 rotate synchronously as a whole. The motor + transmission 6 can drive the whole body by driving one of the display blades 4. After the motor + the transmission 6 is separated from the blades through the electromagnetic clutch 7, the whole display blades 4 rotate freely and passively. The distances between the blades in the figure are not drawn to scale due to the limited size of the figure.

FIG. 6 shows the structure of the blade drive assembly 24. The vane rotary shaft 5 is provided with an electromagnetic clutch 7, a vane position sensor 8 and a vane bearing 9. The electromagnetic clutch 7 functions to disengage and couple the connection between the motor + transmission 6 and the blade rotation shaft 5. The blade position sensor 8 functions to detect the angle of the currently displayed blade 4.

Once the motor + transmission 6 and the blade rotating shaft 5 are disengaged, in the next coupling process, if the driving is carried out together, the displaying function of the billboard is recovered by only adjusting the angle of the displaying blade 4 to 0 degree or 180 degrees. If the display device is driven independently, each motor + transmission 6 adjusts the corresponding display blade 4 to 0 degree or 180 degrees, and the display function of the billboard is recovered.

The above "individual driving" and "common driving" are not absolute. For example, in the case of a total of 10 display blades, each as a group, the two blades are "co-driven" between them, so that there are 5 "individually driven" units in the overall advertising system, requiring 5 motors + transmissions 6.

As shown in fig. 8, the billboard is mounted with a wind sensor 10, a wind direction sensor 11, a vibration sensor 12, a light sensor 13 and a billboard controller 14. The function of the wind sensor 10 is to measure the wind speed in real time. The wind direction sensor 11 functions to measure the wind direction in real time. The function of the shock sensor 12 is: when the billboard begins to shake under the action of any external force (including wind power), the billboard can be collected and simultaneously gives an alarm to an upper system.

In fig. 9 is a functional block diagram of the billboard controller 14. The billboard controller 14 is a unit mounted on the billboard frame 1 for real-time control of the entire billboard. Which comprises the following steps: power supply 15, sensor input 16, motor drive 17, electromagnetic clutch drive 18, MCU19, communication unit 20, and LED 21.
