Description

[0002] At present, with the acceleration of urbanization, the scope of urban traffic coverage is getting wider and wider. Traffic lights are widely used in traffic construction as a traffic guidance method. When pedestrians pass through the road, they need to wait for the instructions of the traffic lights. On hot sunny days or rainy days, it is quite inconvenient for pedestrians to wait, and even cause harm to the pedestrians' bodies. The existing sunshade and rain shelter method usually sets up a sunshade in the waiting area, and pedestrians wait for the guidance of the traffic lights under the sunshade. In this way, the sunshade is usually fixed in the waiting area to avoid movement or tipping due to weather, providing shelter for pedestrians. Since the angle of sunlight will change with time and season, when the angle of sunlight shining on the sunshade is small, the sunshade will have a small shielding area and poor shielding effect. In addition, although the existing sunshade effectively blocks sunlight, it does not effectively utilize sunlight, resulting in a waste of resources, and the installation method of the sunshade requires the space in the waiting area to be occupied, reducing the available area of ​​the waiting area.

[0026] like Figure 1-Figure 4 As shown, a sunshade awning according to a preferred embodiment of the utility model comprises: a support rod 1, a photovoltaic panel 2, a driving mechanism 3, a power mechanism 4, a photosensitive sensor 6 and a control component 7;

[0027] The support rod 1 is vertically arranged on the ground, the photovoltaic panel 2 is rotatably connected to the support rod 1, the driving mechanism 3 is installed on the support rod 1, and the power output end of the driving mechanism 3 is connected to the photovoltaic panel 2 to drive the photovoltaic panel 2 to rotate;

[0028] The photovoltaic panel 2 includes a plurality of photovoltaic panel units 21, and the plurality of photovoltaic panel units 21 are rotatably connected in sequence. The photovoltaic panel units 21 arranged at both ends are defined as end photovoltaic panel units 211, and the remaining photovoltaic panel units 21 are defined as middle photovoltaic panel units 212. The power output end of the driving mechanism 3 is connected to one of the middle photovoltaic panel units 212. A power mechanism 4 is provided between the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 adjacent thereto. The power mechanism 4 is used to drive the end photovoltaic panel unit 211 to rotate relative to the middle photovoltaic panel unit 212.

[0029] The photosensitive sensor is arranged on the photovoltaic panel 2 , and the photosensitive sensor, the driving mechanism 3 and the power mechanism 4 are electrically connected to the control component 7 respectively.

[0030] Specifically, the support rod 1 is vertically fixed to the ground, and the photovoltaic panel 2 is rotatably connected to the side of the support rod 1, such as Figure 1 In the initial state shown, the photovoltaic panel 2 is arranged horizontally, and the photovoltaic panel 2 can also be rotatably connected to the support column of the traffic light. At this time, the support column of the traffic light is equivalent to the support rod 1 in the present application, which can improve the integration of the device and reduce the required installation space; the driving mechanism 3 is arranged on the support rod 1 and connected to the photovoltaic panel 2, and the driving mechanism 3 can drive the photovoltaic panel 2 to rotate; the photosensitive sensor 6 is arranged on the upper surface of the photovoltaic panel 2, and can detect the light intensity and the position of the light source. The photosensitive sensor 6 sends the measured data to the control component 7, and the control component 7 can calculate the illumination angle, so as to obtain the angle required for the photovoltaic panel 2 to rotate perpendicular to the illumination direction, and the driving mechanism 3 drives the photovoltaic panel 2 to rotate a specific angle according to the data of the photosensitive sensor 6.

[0031] In addition, the photovoltaic panel 2 is formed by a plurality of photovoltaic panel units 21 which are connected and spliced ​​in sequence along the length direction of the photovoltaic panel 2. Figure 3 Taking the three photovoltaic panel units 21 shown as an example, a power mechanism 4 is provided between the end photovoltaic panel units 211 at both ends and the middle photovoltaic panel units 212 adjacent to the end photovoltaic panels 211. The power mechanism 4 can make the end photovoltaic panel units 211 and the middle photovoltaic panel units 212 move relative to each other to change the angle between the end photovoltaic panel units 211 and the middle photovoltaic panel units 212. The middle photovoltaic panel unit 212 located in the middle is rotatably connected to the support rod 1 to drive the photovoltaic panel 2 to rotate as a whole; specifically, after the photovoltaic panel 2 rotates and tilts, the power mechanism 4 is started to move the end photovoltaic panel unit 211 located below, reducing the angle between the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212, so as to raise the height of the end photovoltaic panel unit 211 located below, so that there is enough space under the photovoltaic panel 2 for pedestrians to pass.

[0032] On sunny days, the control component 7 controls the driving mechanism 3 to drive the photovoltaic panel 2 to rotate to an angle perpendicular to the direction of light according to the data measured by the light sensor 6. Figure 2 The rotation state shown is Figure 5 As shown, at this time, the photovoltaic panel 2 provides a larger shielding area, which is convenient for pedestrians to shade when waiting for traffic lights. When the photovoltaic panel 2 rotates, the power mechanism 4 drives the end photovoltaic panel unit 211 located below to rotate relative to the middle photovoltaic panel unit 212, so as to raise the height of the end photovoltaic panel unit 211, increase the shielding area of ​​the photovoltaic panel 2 and facilitate the passage and standing of pedestrians below; when the angle of the sun changes, the driving mechanism 3 drives the photovoltaic panel 2 to rotate through the data measured in real time by the photosensor 6, so as to keep the photovoltaic panel 2 perpendicular to the direction of light, and the driving mechanism 3 can be set to work after a certain period of time or after the light angle changes by a certain value, so as to keep the photovoltaic panel 2 in a state of sunshade and high electric energy conversion efficiency, without the need for real-time adjustment with changes in light angle, so as to save the energy required for driving and increase the service life of the device; when it rains, the photosensor 6 detects that the light intensity is low, that is, it sends a signal to drive the driving mechanism 3 to drive the photovoltaic panel 2 to adjust to Figure 1 The initial state shown is convenient for pedestrians to take shelter from the rain. At this time, the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 are kept horizontal, thereby increasing the available area for taking shelter from the rain.

[0033] By utilizing the above-mentioned photovoltaic panel automatic adjustment device, the angle of the photovoltaic panel 2 can be automatically adjusted as the light angle changes, thereby maintaining a larger shielding area, facilitating pedestrian shading and improving the efficiency of solar energy utilization. The generated electricity can be used for the device and traffic lights, which is energy-saving and environmentally friendly. The installation can be completed through the support rod 1, and the installation occupies a small space. The height of the end photovoltaic panel unit 211 can be adjusted, which can facilitate pedestrian passage while increasing the shielding area.

[0034] Preferably, the awning also includes a cross bar 11 rotatably connected to the support rod 1, and the cross bar 11 is perpendicular to the support rod 1; the power output end of the driving mechanism 3 is connected to the cross bar 11, and the photovoltaic panel 2 is arranged on the cross bar 11 and moves with the cross bar 11.

[0035] Specifically, the cross bar 11 is arranged perpendicular to the support bar 1, one end of the cross bar 11 is rotatably connected to the side of the support bar 1, the photovoltaic panel 2 is connected to the cross bar 11, and the driving mechanism 3 is connected to the end of the cross bar 11, driving the cross bar 11 and the photovoltaic panel 2 to rotate to change the angle between the photovoltaic panel 2 and the direction of sunlight.

[0036] Furthermore, the support rod 1 is hollow, and the control assembly 7 and the driving mechanism 3 are both disposed inside the support rod 1 .

[0037] Specifically, a space is provided inside the support rod 1 for installing the control assembly 7, the driving mechanism 3 and the connecting wires, so as to protect the control assembly 7 and the driving mechanism 3 from being damaged by impact.

[0038] Furthermore, the driving mechanism 3 includes: a driving motor 31, a driving bevel gear 32 and a driven bevel gear 33, the driving bevel gear 32 is installed at the power output end of the driving motor 31, and the driven bevel gear 33 is installed at the end of the cross bar 11, and the driving bevel gear 32 and the driven bevel gear 33 are meshed for transmission.

[0039] Specifically, the drive motor 31 is arranged inside the support rod 1, and the drive motor 31 is connected to the cross bar 11 through the active bevel gear 32 and the driven bevel gear 33, and drives the cross bar 11 to rotate through gear transmission; the data measured by the photosensitive sensor 6 is transmitted to the control component 7, and the control component 7 calculates the data, and controls the drive motor 31 to rotate the corresponding number of circles to adjust the rotation angle of the cross bar 11 through the calculated rotation angle parameter; preferably, the number of teeth of the active bevel gear 32 is less than the number of teeth of the driven bevel gear 33, so that the power output shaft of the drive motor 31 needs to rotate multiple circles to adjust the rotation angle of the photovoltaic panel 2, so as to improve the accuracy of adjusting the rotation angle of the photovoltaic panel 2.

[0040] Preferably, two adjacent photovoltaic panel units 21 are rotatably connected via a hinge mechanism 5; the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 rotate relative to each other to achieve a change in the angle between the two.

[0041] Furthermore, the hinge mechanism 5 includes a plurality of hinges 51 , and the two ends of the hinges 51 are respectively fixedly connected to the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 , so that the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 can rotate relative to each other around the rotation axis of the hinges 51 .

[0042] Preferably, the power mechanism 4 includes an electric push rod 41 .

[0043] Specifically, a connector 42 is provided at the connection between the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212 and the electric push rod 41, and both ends of the electric push rod 41 are rotatably connected to the connectors 42 of the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212, so as to rotate to adapt to the change of the angle of the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212; the photovoltaic panel 2 is in Figure 1 In the initial state shown, the electric push rod 41 is in the maximum extension state. When the photovoltaic panel 2 rotates, the electric push rod 41 connected to the end photovoltaic panel unit 211 located below is shortened, and the end photovoltaic panel unit 211 can be pulled upward to reduce the angle between the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212, thereby increasing the height of the end photovoltaic panel unit 211. During this process, the two ends of the electric push rod 41 rotate relative to the connecting piece 42, so that the rotation process of the above-mentioned end photovoltaic panel unit 211 is smooth.

[0044] Preferably, the photovoltaic panel unit 21 includes: a support plate (not shown in the figure), a baffle 22 and a photovoltaic solar panel 23, the photovoltaic solar panel 23 is stacked on the support plate, the baffle 22 is arranged along the periphery of the support plate and encloses the periphery of the photovoltaic solar panel 23.

[0045] Specifically, each photovoltaic solar panel 23 is arranged in a rectangular frame structure surrounded by a support plate and a baffle 22. The lower surface of the photovoltaic solar panel 23 is connected to the support plate, and the baffle 22 abuts against the outer periphery of the photovoltaic solar panel 23, which can protect the photovoltaic solar panel 23 from being damaged by impact from the side and bottom. The rectangular frame structure surrounded by the support plate and the baffle 22 moves with the photovoltaic solar panel 23 in the middle, and the baffles 22 are hinged with the corresponding hinge mechanism 5 to ensure that the photovoltaic panel unit 21 can rotate smoothly.

[0046] Preferably, the awning further comprises: a battery (not shown in the figure), which is electrically connected to the photovoltaic panel 2, the driving mechanism 3, the photosensor 6 and the control component 7 respectively.

[0047] Specifically, the photovoltaic panel 2 is electrically connected to the battery, and the electric energy generated by the photovoltaic panel 2 can be stored through the battery for subsequent use; the battery is electrically connected to the control component 7, the drive mechanism 3 and the photosensitive sensor 6 respectively, and can provide electric energy for the control component 7, the drive mechanism 3 and the photosensitive sensor 6. Furthermore, the battery can also be connected to traffic lights and other road traffic equipment to provide electric energy, which is energy-saving and environmentally friendly; components such as the drive mechanism 3 and the photosensitive sensor 6 are also electrically connected to the mains, which can ensure the normal operation of the device when the battery cannot provide effective electric energy.

[0048] Preferably, the height of the photovoltaic panel 2 from the ground is 3 meters to 5 meters, and the length of the photovoltaic panel 2 is 4 meters to 6 meters.

[0049] Specifically, the connection between the photovoltaic panel 2 and the support rod 1 is 3 meters away from the ground, that is, the middle part of the photovoltaic panel 2 is 3 meters away from the ground, ensuring that when the photovoltaic panel 2 is in an initial horizontal state, there is enough space below for pedestrians to pass; preferably, the maximum rotation angle of the photovoltaic panel 2 is 60°. When the illumination angle requires the photovoltaic panel 2 to rotate at an angle greater than 60°, the photovoltaic panel 2 rotates to 60° and maintains this position, which can avoid the photovoltaic panel 2 from rotating at an excessively large angle, thereby squeezing the passage space below. There is no need to install the photovoltaic panel 2 at too high a height. When the illumination angle is too large, it is usually in the early morning or evening. At this time, the demand for shading and the efficiency of photovoltaic power generation are relatively low, and no corresponding action is required. The length of the photovoltaic panel 2 is selected to be 4 meters. When the photovoltaic panel 2 rotates to 60°, the end photovoltaic panel unit 211 located below rotates to a horizontal state. At this time, it can be ensured that the end photovoltaic panel unit 211 located below is more than 2 meters away from the ground, which will not block pedestrians and facilitate pedestrian passage.

[0050] In addition, a rain sensor can be set on the upper surface of the photovoltaic panel 2. The rain sensor is electrically connected to the control component 7 to detect whether it is raining. According to the rainfall situation, the driving mechanism 3 is controlled to drive the photovoltaic panel 2 to a horizontal state to provide a rain shelter function.

[0051] The working process of the utility model is as follows: the device is vertically installed near the traffic signal waiting area, and the photovoltaic panel 2 is located above the traffic signal waiting area; when the photosensor 6 on the upper surface of the photovoltaic panel 2 detects light, it determines whether it is necessary to block the light according to the light intensity. When it is necessary to block the sunlight, the control component 7 calculates the required rotation angle of the cross bar 11 and the required rotation angle of the end photovoltaic panel unit 211 according to the data detected by the photosensor 6, and the motor 31 drives the cross bar 11 to drive the photovoltaic panel 2 to rotate to an angle perpendicular to the light direction. While the driving motor 31 drives the cross bar 11 to rotate, the electric push rod 41 contracts and pulls the end photovoltaic panel unit 211 located below to rotate to a horizontal position; pedestrians can wait in the shade formed by the photovoltaic panel 2 and can pass under the photovoltaic panel 2.

[0052] When the illumination angle changes over time during a day, the photosensor 6 measures the relevant data in real time. Based on the measured illumination data, the drive motor 31 drives the photovoltaic panel 2 to adjust its angle to keep it perpendicular to the illumination direction. When the photovoltaic panel 2 rotates to 60°, if the illumination angle continues to increase, the photovoltaic panel 2 maintains the same angle. When the illumination intensity is detected to be less than 10,000 l x, the photovoltaic panel 2 returns to its initial state.

[0053] When it rains, the rain sensor detector detects rainfall or the photosensor 6 detects that the light intensity is too low, the drive motor 31 drives the cross bar 11 to rotate, and the electric push rod 41 also extends to rotate the end photovoltaic panel unit 211 and the middle photovoltaic panel unit 212, and finally rotates the photovoltaic panel 2 to its initial state and is placed horizontally, so that pedestrians can take shelter from the rain under the photovoltaic panel 2.

[0054] In summary, the embodiment of the utility model provides an automatic adjustment device for photovoltaic panels, which automatically rotates the photovoltaic panel 2 according to the light angle by setting a photosensitive sensor 6, so that the photovoltaic panel 2 maintains the maximum sunlight blocking area, provides sunshade for pedestrians while improving the efficiency of photovoltaic power generation, saving energy and being environmentally friendly; the installation space required for installing this device is small, reducing space occupancy; and it also takes into account the rain shelter function, with high practicality and no impact on the normal passage of pedestrians.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
