The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. 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.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1 to 3, the present embodiment provides a total efficiency optimization and control system 1000 for cogeneration, where the total efficiency optimization and control system 1000 includes: a base (not shown), a reference shaft 100, a mount 200, a control box 300, a photosensitive assembly 400, and a controller (not shown).
The reference shaft 100 is rotatably installed at the base and driven by a driver (not shown) for driving the reference shaft 100 to rotate, thereby adjusting the angle of the reference shaft 100.
The mount 200 is fixedly attached to the reference shaft 100, and the mount 200 has an attachment surface 210 for attaching the cogeneration module.
The control box 300 is fixedly mounted to the mounting base 200 or the reference shaft 100, and in the present embodiment, the control box 300 is fixedly mounted to the reference shaft 100.
The surface of the inner wall of the control box 300 is provided with a first light absorption layer 310, and the photosensitive assembly 400 is installed in the control box 300. The control box 300 is provided with a light hole 320, the opening direction of the light hole 320 is perpendicular to the mounting surface 210, and the inner end of the light hole 320 faces the photosensitive part of the photosensitive element 400.
Wherein, the photosensitive assembly 400 and the driver are connected with the controller by signals. When the photosensitive element 400 detects the light signal, the controller controls the driver to stop. When the light-sensitive component 400 does not detect the light signal, the controller controls the driver to start rotating the reference shaft 100 to adjust the orientation of the mounting base 200 until the light-sensitive component 400 detects the light signal again.
In the using process, when the total efficiency optimization regulation and control system 1000 is installed, the reference shaft 100 of the total efficiency optimization regulation and control system 1000 is arranged along the north-south direction, the solar combined heat and power assembly is installed on the installation surface 210 of the installation base 200, and the photovoltaic module and the photothermal module of the solar combined heat and power assembly are arranged in parallel to the installation surface 210.

As time goes by, the irradiation angle of the light changes, which may cause the light not to irradiate the photosensitive portion of the photosensitive element 400 due to the blocking of the casing of the control casing 300, and the photosensitive element 400 may not detect the light signal. At this time, the controller controls the driver to start rotating the reference shaft 100, so that the mounting surface 210 of the mounting base 200 rotates toward the west (i.e., rotates in the light irradiation direction),
by adjusting the orientation of the mounting base 200, the light can smoothly pass through the light hole 320 and irradiate the photosensitive portion of the photosensitive element 400 again, the photosensitive element 400 detects the light signal again, and the mounting base 200 stops deflecting, so that the light is still directly irradiated to the photovoltaic module and the photothermal module.
Through this design, can guarantee that photovoltaic module and light and heat module all are in the state of light direct projection more in time, make photovoltaic module and light and heat module can be in best operating condition for a long time, improved the utilization ratio to solar energy resource greatly.
Generally, the total efficiency optimization regulation and control system 1000 for cogeneration further improves the resource utilization rate, realizes automatic regulation and control, can keep the system in a better working state in different time periods, and has higher energy supply and output of cogeneration.
It should be noted that, after sunset, the controller can be used to control the reference shaft 100 to rotate, so that the mounting seat 200 is reset and faces the east again, and thus the work of the next day is ready.
Referring to fig. 1 to 8, in the present embodiment, the control box 300 further includes a first cylinder 330, the first cylinder 330 is coaxial with the light hole 320, and an outer diameter of the first cylinder 330 is adapted to an aperture of the light hole 320. The first cylinder 330 is received in the light hole 320, an outer end of the first cylinder 330 is flush with an outer surface of the control box 300, and an inner end of the first cylinder 330 extends toward the photosensitive element 400.
The first cylinder 330 can improve the blocking effect on light, after the deviation of the irradiation angle relative to the axis direction of the light hole 320 occurs, the oblique light can be blocked by the cylinder wall of the first cylinder 330 and can not be injected into the control box 300, the amount of light entering the control box 300 in the oblique state is greatly reduced, and the control precision is improved.
Further, the control box 300 is further provided with a second cylinder 340. The second cylinder 340 is coaxially arranged with the first cylinder 330, and the outer diameter of the second cylinder 340 is matched with the inner diameter of the first cylinder 330. Along the axial direction of the first cylinder 330, the second cylinder 340 is movably disposed in the control box 300 and driven by the first driving assembly 342.
The second cylinder 340 has a first movement stop point and a second movement stop point. When the second cylinder 340 is located at the first motion stop point, the second cylinder 340 is accommodated in the first cylinder 330, the outer end of the second cylinder 340 is flush with the outer end of the first cylinder 330, and the inner end of the second cylinder 340 is flush with the inner end of the first cylinder 330. When the second cylinder 340 is located at the second motion stop point, the second cylinder 340 is located at a side of the photosensitive portion of the photosensitive element 400 away from the first cylinder 330.
The control box 300 is also provided with a third cylinder 350. The third cylinder 350 is coaxially disposed with the second cylinder 340, and the outer diameter of the third cylinder 350 is adapted to the inner diameter of the second cylinder 340. Along the axial direction of the second cylinder 340, the third cylinder 350 is movably disposed in the control box 300 and driven by the second driving assembly 353.
The third cylinder 350 has a third movement dead point and a fourth movement dead point. When the third cylinder 350 is located at the third motion stop point, the third cylinder 350 is accommodated in the second cylinder 340, the outer end of the third cylinder 350 is flush with the outer end of the second cylinder 340, and the inner end of the third cylinder 350 is flush with the inner end of the second cylinder 340. When the third cylinder 350 is located at the fourth motion stop point, the third cylinder 350 is located at a side of the photosensitive portion of the photosensitive element 400, which is far away from the first cylinder 330.
Through this design, when the weather is clear, the solar energy resource at this moment is very abundant, and light intensity is high moreover, in order to make full use of light energy under this kind of high-quality environment as far as possible, we need to make photovoltaic module and light and heat module receive the light as much as possible and penetrate directly. To achieve this, the second cylinder 340 can be driven to the first motion stop point by the first driving assembly 342, and the third cylinder 350 can be driven to the third motion stop point by the second driving assembly 353, at which time, light can only be irradiated into the control box 300 through the cylinder cavity of the third cylinder 350. Since the inner diameter of the third cylinder 350 is smaller than that of the first cylinder 330, the amount of light that can be irradiated into the control box 300 through the third cylinder 350 is smaller than that of light that can be irradiated into the control box 300 through the first cylinder 330, and further, when the irradiation angle of light is slightly deflected with respect to the axial direction of the third cylinder 350, the light is blocked by the third cylinder 350 and cannot be irradiated into the control box 300, and the controller controls the deflection of the mounting surface 210.
Like this, when the illumination angle takes place littleer deflection, the controller will control reference axis 100 angle modulation, ensures that light shines directly in photovoltaic module and light and heat module, has improved the regulating frequency greatly, also makes photovoltaic module and light and heat module can all keep the state of being shined directly by light in the longer time, has improved photovoltaic module and light and heat module's efficiency greatly, improves greatly the utilization ratio of solar energy resource.
On the other hand, when the weather is bad, the solar energy resource is limited, the light intensity is low, and the efficiency of the photovoltaic module and the photo-thermal module is in a low valley. If the above adjustment is still adopted, the energy consumption of the system itself will be obviously increased, which is not suitable. At this time, the third cylinder 350 may be driven to the fourth motion stop point by the second driving assembly 353, and the second cylinder 340 may be driven to the second motion stop point by the first driving assembly 342. In this state, light is irradiated into the control box 300 through the first cylinder 330, the cross-sectional area of the cavity of the first cylinder 330 is larger, the irradiation surface of the light is larger, and when the irradiation angle of the light is deflected slightly, a part of the light may still be irradiated to the photosensitive portion of the photosensitive element 400 without being blocked by the first cylinder 330. Therefore, when the irradiation angle is slightly changed, the controller cannot be actuated, the frequency of the rotation shaft adjustment is reduced, and the power consumption of the system is reduced.
The second cylinder 340 and the third cylinder 350 are provided, so that more adjusting ways of the irradiation surface are provided for adapting to different weather conditions.
In cooperation, the total efficiency optimization and regulation system 1000 further includes a light intensity detection component (not shown in the figure) for detecting the light intensity in the environment, and the light intensity detection component, the first driving component 342 and the second driving component 353 are all in signal connection with the controller.
The controller is used for presetting and storing a corresponding relation between light intensity and the opening degree of the light transmission hole 320, and is also used for controlling the second cylinder 340 to move to a second motion stop point and controlling the third cylinder 350 to move to a fourth motion stop point according to the ambient light intensity detected by the light intensity detection assembly based on the corresponding relation between the light intensity and the opening degree of the light transmission hole 320, so that the aim of adjusting the opening degree of the light transmission hole 320 is fulfilled.
Specifically, the "correspondence between light intensity and opening of the light-transmitting hole 320" includes: a first light intensity range, a second light intensity range, and a third light intensity range. The first light intensity range is greater than the second light intensity range, which is greater than the third light intensity range.
When the intensity of the ambient light detected by the light intensity detecting assembly is within the first light intensity range, the controller controls the second cylinder 340 to move to the first motion stop point, and controls the third cylinder 350 to move to the third motion stop point. At this time, the external light is sufficient, so that the adjustment frequency is increased to ensure that the photovoltaic module and the photothermal module can be in a state of being directly irradiated by the light for a longer time.
When the intensity of the ambient light detected by the light intensity detecting assembly is within the second light intensity range, the controller controls the second cylinder 340 to move to the first motion stop point, and controls the third cylinder 350 to move to the fourth motion stop point. At this moment, external light is sufficient relatively, when reducing system's power consumption to a certain extent, control adjusting frequency is in higher state and guarantees that photovoltaic module and light and heat module can all be in the state of being penetrated directly by the light in longer time.
When the intensity of the ambient light detected by the light intensity detecting assembly is within the third light intensity range, the controller controls the second cylinder 340 to move to the second motion stop point, and controls the third cylinder 350 to move to the fourth motion stop point. At this time, the external light is relatively insufficient, and the power consumption of the system is reduced as much as possible by reducing the adjustment frequency, so that the photoelectric module and the photo-thermal module can also perform adaptive posture adjustment according to the change of the irradiation angle.
Through the means, the utilization rate of solar energy is improved, and the energy margin is increased.
Further, a first stopping portion 341 is disposed at an end of the second cylinder 340 away from the outer end of the light hole 320, and when the second cylinder 340 is located at the first motion dead point, the first stopping portion 341 abuts against the inner end of the first cylinder 330. The end of the third cylinder 350 away from the outer end of the light-transmitting hole 320 is provided with a second stopping portion 351, and when the third cylinder 350 is located at the third motion stop point, the second stopping portion 351 abuts against the inner end of the second cylinder 340.
Still be provided with reference column 360 in the control box 300, reference column 360 and the coaxial setting of first barrel 330, the one end that first barrel 330 was kept away from to reference column 360 and the inner wall fixed connection of control box 300, the diameter of reference column 360 and the internal diameter looks adaptation of third barrel 350. The photosensitive element 400 is mounted on an end surface of the positioning column 360 close to the first cylinder 330, and the diameter of the photosensitive element 400 is smaller than that of the positioning column 360.
The first drive assembly 342 and the second drive assembly 353 are both linear drive mechanisms, including but not limited to screw mechanisms. When the third cylinder 350 is located at the fourth motion stop point, the positioning column 360 is sleeved with the third cylinder 350. When the second cylinder 340 is located at the second motion stop point, the third cylinder 350 is sleeved with the second cylinder 340.
This mode is simple high-efficient, and can play the stabilizing action to reference column 360.

The surfaces of the inner walls of the third cylinder 350 are provided with fourth light absorbing layers 352.
The first cylinder 330 and the second cylinder 340 are used to transmit light when external light is weak. The first mirror layer 331 and the second mirror layer enable a portion of light irradiated to the inner wall of the cylinder to be reflected into the control box 300, increasing the probability of irradiating the photosensitive portion of the photosensitive element 400, thereby contributing to further reducing the adjustment frequency. The second light absorbing layer 332 and the third light absorbing layer 344 can prevent excessive light from entering the control box 300 through reflection, and prevent the adjusting gap from being too long to affect the normal operation of the photovoltaic module and the photothermal module.
Wherein, along the axial direction of the first cylinder 330, the length of the second light absorbing layer 332 is greater than that of the third light absorbing layer 344, so as to adapt to the use requirement of the first cylinder 330 in the environment with weaker light.
