The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, which shows a schematic structural diagram of an outdoor projection apparatus provided in an embodiment of the present invention, the outdoor projection apparatus may include a heliostat 1, a fresnel lens 2 installed on an outdoor support, and a rotating shaft 3 installed between the outdoor support and the fresnel lens 2, the rotating shaft 3 is installed with a concentrating photovoltaic panel 4, a projection unit 5, and a conversion mechanism, and may further include an energy storage device and a heat dissipation device connected to the concentrating photovoltaic panel 4 and the projection unit 5, where:
the projection unit 5 may include a light source 51 and a slide 52 opposite to the light source 51 and containing projection information, and the geometric center of the concentrating photovoltaic panel 4 and the geometric center of the slide 52 are both coincident with the focal point of the fresnel lens 2;
the conversion mechanism is used for converting between the concentrating photovoltaic panel 4 and the projection unit 5 so that the concentrating photovoltaic panel 4 or the projection unit 5 is opposite to the Fresnel lens 2.
The fresnel lens 2 is configured to receive sunlight reflected by the heliostat 1 and then vertically incident thereto when opposed to the concentrating photovoltaic panel 4, and to irradiate the sunlight onto the concentrating photovoltaic panel 4, and is configured to enlarge and image projection information when opposed to the projection unit 5.
The outdoor projection device may include a heliostat 1, a fresnel lens 2 installed on an outdoor support (specifically, a building, an outdoor enclosure, a bus stop board, etc.), a rotating shaft 3 installed between the outdoor support and the fresnel lens 2, a concentrating photovoltaic panel 4 and a projection unit 5 installed on the rotating shaft 3, and a switching mechanism installed on the rotating shaft 3, where the projection unit 5 specifically includes a light source 51 and a slide 52 opposite to the light source 51, and the slide 52 includes projection information to be projected, where the projection information may specifically be text advertisement information, image advertisement information, or both text advertisement information and image advertisement information, and the light source 51 may specifically be an LED (light Emitting Diode) light source, etc. In addition, the outdoor projection equipment further comprises an energy storage device and a heat dissipation device, wherein the energy storage device and the heat dissipation device are connected with the concentrating photovoltaic cell panel 4 and the projection unit 5.
The heliostat 1 used in the advertisement projection device may be a dual-axis tracking heliostat, and includes a support shaft 101 for supporting, a reflective mirror 102, and a tracking device, where the tracking device mainly includes a solar elevation angle motor 103 and a solar azimuth angle motor 104.
When the power generation state is started in the daytime, the conversion mechanism can drive the rotating shaft 3 to rotate, so that the concentrating photovoltaic cell panel 4 is opposite to the Fresnel lens 2, wherein the geometric center of the concentrating photovoltaic cell panel 4 is opposite to the geometric center of the Fresnel lens 2. At this time, the solar altitude motor 103 and the solar azimuth motor 104 can adjust the posture of the reflective mirror 102 according to the movement time of the sun, so that the sunlight at different times can vertically irradiate the fresnel lens 2 after being adjusted, and then the light rays are irradiated onto the concentrating photovoltaic cell panel 4 through the light-condensing effect of the fresnel lens 2, so that the concentrating photovoltaic cell panel 4 can generate electricity by using the irradiated sunlight, and the generated electricity can be stored in the energy storage device. When the power generated by the concentrating photovoltaic cell panel 4 is abundant, the redundant power can be adjusted, and grid connection is realized. The heat dissipation device connected with the concentrating photovoltaic cell panel 4 is used for conducting away heat generated by the concentrating photovoltaic cell panel 4 during power generation in time so as to reduce the power generation temperature and improve the power generation efficiency.
When the projection state is enabled at night or other time, the switching mechanism may rotate the rotating shaft 3 such that the projection unit 5 is opposite to the fresnel lens 2, wherein the geometric center of the slide 52 included in the projection unit 5 is opposite to the fresnel lens 2.

The heat dissipation device connected to the projection unit 5 is used for dissipating heat generated by the light source 51 during operation in time, so as to reduce the operating temperature of the light source 51, thereby achieving the energy-saving effect. When the electric energy stored in the energy storage device cannot completely meet the requirement of the light source 51, the light source 51 can be supplied with power through the commercial power, so that the outdoor advertising equipment can continue to work. Of course, the light source 51 may also be directly powered by the commercial power according to actual requirements.

In addition, when the projection content of the outdoor projection device needs to be changed, only the slide 52 needs to be changed, so that the outdoor projection device can be easily replaced, and the replacement cost can be reduced.
It should be noted that, because the effective area of the reflecting surface of the heliostat 1 is the projection area of the reflecting mirror 102 under the sunlight, the area of the fresnel lens 2 may be slightly smaller than the area of the reflecting mirror 102, so as to save the materials required for manufacturing the fresnel lens 2 and improve the utilization rate of the unit area. In addition, referring to fig. 2, a layout of a fresnel lens provided by an embodiment of the present invention on a building is shown. When the fresnel lens 2 is installed on a building, it should be arranged to avoid the original objects 6 of the building, such as windows, air conditioners, etc.
According to the technical scheme, in the power generation state, the concentrating photovoltaic cell panel arranged on the rotating shaft is opposite to the Fresnel lens through the switching mechanism, at the moment, the heliostat is used for reflecting sunlight, the reflected sunlight is vertically incident to the Fresnel lens, and then the reflected sunlight is focused on the concentrating photovoltaic cell panel through the Fresnel lens to generate power and store the generated power in the energy storage device; when the projection state needs to be switched, the projection unit is opposite to the Fresnel lens through the switching mechanism, at the moment, the light source emits light by using electric energy in the energy storage device and irradiates the slide containing projection information, then the projection information on the slide is amplified and imaged by using the Fresnel lens, and the heat is dissipated through the heat dissipation device in the power generation state or the projection state. Because above-mentioned mode can make spotlight photovoltaic cell board generate electricity and supply power through heliostat, fresnel lens, and can utilize fresnel lens to enlarge the formation of image to projection information, consequently, then can reduce the electric energy that advertisement projection consumed to can reduce light pollution, reduce the pollution that causes the environment, when needs are changed projection content in addition, only need change the slide can, thereby can realize advertisement projection's easily change.

and the conical prism 7 is positioned on the light receiving surface of the concentrating photovoltaic cell panel 4 and is used for concentrating light for the concentrating photovoltaic cell panel 4 when the Fresnel lens 2 is opposite to the concentrating photovoltaic cell panel 4.
A conical prism 7 may be mounted on the light receiving surface of the concentrating photovoltaic cell panel 4. When the conversion mechanism converts the concentrating photovoltaic cell panel 4 to the position opposite to the Fresnel lens 2, the conical prism 7 can condense sunlight again, so that light falling on the concentrating photovoltaic cell panel 4 is more concentrated, the conversion efficiency of the concentrating photovoltaic cell panel 4 is improved, and the output power of the concentrating photovoltaic cell panel 4 is improved.
Referring to fig. 3, a schematic structural diagram of a rotating shaft and a device disposed on the rotating shaft according to an embodiment of the present invention is shown. In the outdoor projection device provided by the embodiment of the invention, the heat dissipation device can be a heat dissipation fin 8.

The heat dissipation fins 8 are also called fins or fins, and can increase the heat transfer area, reduce the thermal resistance of convective heat transfer, and enhance the heat transfer capability, thereby improving the power generation efficiency of the concentrating photovoltaic cell panel 4, and reducing the power consumption of the projection unit 5 to save the power.
Referring to fig. 4, a schematic structural diagram of another outdoor projection device provided in an embodiment of the present invention is shown. According to the outdoor projection equipment provided by the embodiment of the invention, the number of the rotating shafts 3 can be multiple, each rotating shaft 3 is provided with a plurality of projection units 5, a plurality of concentrating photovoltaic cell panels 4 and a plurality of Fresnel lenses 2, wherein the plurality of rotating shafts 3 are arranged in parallel, and each concentrating photovoltaic cell panel 4 and each projection unit 5 correspond to one Fresnel lens 2.
Considering that the fringe reflection loss increases as the size of the fresnel lens 2 increases, for example, when a fresnel lens 2 of 1000 × 1000mm is used, the light condensing efficiency is only 70%, when a fresnel lens 2 of 500 × 500mm or 300 × 300mm is used, the light condensing efficiency reaches 80% to 90%, and when the size of the fresnel lens 2 is too large, burning of the light condensing photovoltaic panel 4 is caused, and therefore, the fresnel lens 2 provided on the rotating shaft 3 may be divided into a plurality of pieces to increase the light condensing efficiency and reduce the influence on the light condensing photovoltaic panel 4 while matching the area of the heliostat 1 (wherein the size of the mirror 102 included in the heliostat 1 is generally not limited). Each fresnel lens 2 corresponds to one concentrating photovoltaic cell panel 4 and one projection unit 5, and the slides 52 can be placed in different projection units 5 in a certain order, that is, each rotating shaft 3 can be provided with a plurality of projection units 5 and a plurality of concentrating photovoltaic cell panels 4. Besides, limiting the size of the fresnel lens 2 can improve the imaging quality of the projection unit 5.
In addition, a plurality of rotating shafts 3 can be arranged in the outdoor projection equipment, and the rotating shafts 3 can be arranged on the outdoor supporting body in parallel to meet the projection requirement.
In practical application, the area of the reflective mirror 102 and the total area of the multiple fresnel lenses 2 can be selected according to practical factors such as the size of the outdoor support, the area required by projection, and the like. After the total area of the fresnel lenses 2 is determined, the size of each fresnel lens 2 can be determined.
See fig. 3 and 4. According to the outdoor projection equipment provided by the embodiment of the invention, the rotating shaft 3 is a hollow rotating shaft 31, and water is filled in the hollow rotating shaft 31;

the water heater comprises a hot water pipe 9 connected with the top of a hollow rotating shaft 31, a cold water pipe 10 connected with the bottom of the hollow rotating shaft 31, a water storage tank 11 connected with the hot water pipe and the cold water pipe 10, and sealing devices, wherein the sealing devices are arranged at the joint of the hollow rotating shaft 31 and the hot water pipe 9 and the joint of the hollow rotating shaft 31 and the cold water pipe 10.
The rotating shaft 3 included in the outdoor projection device may be specifically a hollow rotating shaft 31, and the hollow rotating shaft 31 is filled with water, and of course, other working mediums may be filled inside the hollow rotating shaft 31. Wherein, the heat dissipation device is located in the hollow rotating shaft 31 (i.e. located in the working medium inside the hollow rotating shaft 31).
Considering that when the outdoor projection device works, the heat dissipation device heats the water inside the hollow rotating shaft 31, the density of the heated water is reduced, and then the heated water flows upwards, therefore, a hot water pipe 9 connected with the hollow rotating shaft 31 and a water storage tank 11 connected with the hot water pipe 9 can be arranged at the top of the hollow rotating shaft 31 to transfer the heat generated by the concentrating photovoltaic panel 4 and the projection unit 5. After the heated water reaches the water storage tank 11, the temperature of the water is gradually decreased and the density of the water is gradually increased, so that the water flows downward, and in order to supplement the amount of water required inside the hollow rotary shaft 31 and to save the amount of water, a cold water pipe 10 connected to the water storage tank 11 and the bottom of the hollow rotary shaft 31 may be provided to feed the water having a relatively low temperature in the water storage tank 11 into the hollow rotary shaft 31 through the cold water pipe 10, thereby supplementing the water flowing upward from the hollow rotary shaft 31.
After the rotating shaft 3 is set as the hollow rotating shaft 31 and water is filled therein, in order to prevent water inside the hollow rotating shaft 31 from flowing out from the connection between the pipeline and the hollow rotating shaft 31 when the switching mechanism rotates the hollow rotating shaft 31, sealing means may be provided at the connection between the hollow rotating shaft 31 and the hot water pipe 9 and at the connection between the hollow rotating shaft 31 and the cold water pipe 10, wherein the sealing means may specifically include the seal ring 12 and the end cap 13, and of course, other types of sealing means may be employed to prevent water from flowing out.
When the outdoor support body is specifically a building, the Fresnel lens 2 can be arranged on one side of the back shade surface of the building, so that the projection effect can be achieved, and the lighting of the building cannot be influenced. Specifically, reference may be made to fig. 5, which shows a schematic diagram of an installation of the advertisement projection device provided by the embodiment of the present invention on a building, wherein the building is located on one side of a road, a heliostat 1 is installed on the other side of the road, and a side on which a fresnel lens 2 is installed is a shadow side of the building.

Wherein the radiator 18 is arranged between the first water valve 16 and the second water valve 17; the temperature sensing instrument 19 is disposed near the top of the hollow rotary shaft 31, i.e., at a position close to the hot water pipe 9.
The temperature sensing instrument 19 is used to detect the temperature of water at the top position of the hollow rotary shaft 31. When the detected water temperature is higher than the water temperature set according to the outdoor support requirement (i.e. the preset water temperature), the water pump 15, the first water valve 16 and the second water valve 17 are all in an open state, that is, the water inside the circulating water pipe 14 is cooled and cooled by the radiator 18, so that the redundant heat is dissipated.
