Description

Technical Field

[0001] This utility model relates to the field of heliostat technology, specifically to a flip-up multifunctional heliostat. Background Technology

[0002] In agricultural and livestock production, transparent greenhouses are widely used for growing vegetable crops or raising livestock to provide a suitable growing environment. However, in winter or when sunlight is insufficient, plants inside the greenhouse often suffer from insufficient light due to oblique sunlight, and the environment may also be relatively cold, which is detrimental to crop growth and the activity of plants and animals. To solve this problem, the traditional method uses multi-faceted heliostats to reflect sunlight into the greenhouse to supplement light and raise the temperature, promoting crop growth and plant and animal activity. However, in the hot summer, when there is plenty of sunlight, plants and animals do not need much sunlight, and at this time the heliostats are easily left idle, resulting in a waste of resources.

[0003] On the other hand, in tower-type solar thermal power plants, numerous heliostats are arranged around the tower. The main function of these heliostats is to reflect sunlight to the absorber tower, where the heat energy is absorbed by the collector and converted into electricity. However, in actual operation, the area of ​​light reflected by each heliostat varies throughout the day due to the cosine effect, as the sun's position changes. In the morning, when the sun is in the east, the heliostats on the west side of the absorber tower reflect more light, while those on the east side reflect less. In the afternoon, when the sun is in the west, the situation reverses, with the western heliostats reflecting less light. Furthermore, the farther the mirror is from the absorber tower, the lower the reflection efficiency, causing these heliostats to be unable to effectively utilize solar energy resources for certain periods. Traditional methods often improve reflection efficiency by optimizing the layout and adjusting the angle of the heliostats. However, these methods have limitations, and the potential for further improvement in reflection efficiency is limited. Utility Model Content

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In agricultural and livestock production, transparent greenhouses are widely used for growing vegetable crops or raising livestock to provide a suitable growing environment. However, in winter or when sunlight is insufficient, plants inside the greenhouse often suffer from insufficient light due to oblique sunlight, and the environment may also be relatively cold, which is detrimental to crop growth and the activity of plants and animals. To solve this problem, the traditional method uses multi-faceted heliostats to reflect sunlight into the greenhouse to supplement light and raise the temperature, promoting crop growth and plant and animal activity. However, in the hot summer, when there is plenty of sunlight, plants and animals do not need much sunlight, and at this time the heliostats are easily left idle, resulting in a waste of resources.

[0030] On the other hand, in tower solar thermal power plants, numerous heliostats are arranged around the tower. The main function of these heliostats is to reflect sunlight to the absorber tower, where the heat energy is absorbed by the collector and converted into electricity. However, in actual operation, the reflectivity of the heliostats is affected by changes in the sun's position and differences in the distance between the heliostats and the absorber tower. Especially in areas far from the absorber tower, the reflectivity of the heliostats decreases significantly, causing them to be unable to effectively utilize solar energy resources for certain periods. Traditional methods often improve reflectivity by optimizing the layout of the heliostats and adjusting their angles. However, these methods have limitations, particularly in areas far from the absorber tower where the potential for improvement in reflectivity is limited.

[0031] To address the above technical issues, such as Figures 1 to 5 As shown, this application embodiment provides a flip-up multifunctional heliostat, including a column 1, an angle adjustment mechanism, a crossbar 2, and a light-collecting component 3; the angle adjustment mechanism connects the column 1 and the crossbar 2, and is used to drive the crossbar 2 to rotate along its own axis; the light-collecting component 3 is a plate structure, and the light-collecting component 3 is fixedly connected to the crossbar 2; one end face of the light-collecting component 3 is provided with a plane mirror 4, and the other end face is provided with a photovoltaic panel 5.

[0032] The column 1 serves as the support for the overall structure, ensuring the stability of the heliostat. An angle adjustment mechanism connects the column 1 and the crossbar 2, driving the crossbar 2 to rotate along its own axis, thus flexibly adjusting the pitch angle of the light-collecting component 3. The light-collecting component 3 is a plate structure with a flat mirror 4 on one end face. In winter or when sunlight is insufficient, this mirror reflects sunlight to a fixed location inside the greenhouse to supplement light, increase temperature, and promote crop growth. In summer, when there is ample sunlight or when power generation is needed, the angle adjustment mechanism rotates the light-collecting component 3 180 degrees, so that the photovoltaic panel 5 on its other end face the sun to generate photovoltaic power, achieving efficient utilization of solar energy.

[0033] like Figure 6 As shown, the heliostat controller stores two or more sets of tracking data. The heliostat's tracking mode can be switched manually or automatically according to actual needs. When switching to mirror tracking mode, the heliostat mainly tracks the sun's position and adjusts its reflection angle to ensure that sunlight accurately illuminates the target location. When switching to photovoltaic panel tracking mode, the photovoltaic panel needs to be facing the sun to generate photovoltaic power and achieve efficient utilization of solar energy.

[0034] The flip-up multifunctional heliostat in this embodiment integrates two functions: a planar mirror body 4 and a photovoltaic panel 5, by setting a flip-up light-collecting component 3. It can reflect sunlight to supplement the light for crops in the greenhouse to promote growth and increase the temperature in winter or when there is insufficient light. In summer or when there is plenty of sunlight, it can switch to power generation mode and use the photovoltaic panel 5 to generate electricity to drive the air conditioner or fan in the greenhouse to cool it down, thus achieving a multifunctional function.

[0035] In addition, this structural design improves the power generation efficiency of photovoltaic panels, saves on support costs, and reduces land use area. At the same time, through intelligent control, the heliostat can automatically select the working mode according to the environment inside the greenhouse, improving the efficiency of agricultural and livestock breeding and saving energy consumption and breeding costs.

[0036] For example, in a tower solar thermal power plant, when the reflectivity is very low, the heliostat can be flipped so that the photovoltaic panels face the sun. This utilizes 100% of the support area. In this case, photovoltaic power generation is much more efficient than mirror-based solar thermal power generation, which can make full use of solar energy resources and improve energy efficiency.

[0037] In some embodiments, the angle adjustment mechanism includes a housing 6 and a first conductive slip ring 7; the housing 6 is connected to the top of the column 1, the crossbar 2 passes through the housing 6 and rotates relative to it, the first conductive slip ring 7 includes an inner ring 8 and an outer ring 9, the inner ring 8 is fixedly sleeved on the crossbar 2, the outer ring 9 is rotatably sleeved on the outside of the inner ring 8 and electrically connected to the inner ring 8, one end face of the outer ring 9 is fixedly connected to the side wall of the housing 6; the inner ring 8 is connected to an inner ring terminal 10, and the outer ring 9 is connected to an outer ring terminal 11; the crossbar 2 is provided with a through cavity, and the part of the crossbar 2 located inside the housing 6 is provided with a wire hole 12, the wire of the photovoltaic panel 5 enters the through cavity from the port of the crossbar 2 and is led out from the wire hole 12 to connect to the inner ring terminal 10, and the wire of the outer ring terminal 11 is used to connect to external equipment.

[0038] Specifically, the housing 6 is fixed to the top of the column 1, and the crossbar 2 passes through the housing 6 and can rotate 360 ​​degrees relative to it. The inner ring 8 is tightly fixed on the crossbar 2 and rotates with the crossbar 2; the outer ring 9 is rotatably fitted on the outside of the inner ring 8 and is firmly connected to the side wall of the housing 6, maintaining relative stillness. The inner ring 8 is provided with an inner ring terminal 10 for connecting to the circuit of the rotating part; the outer ring 9 is provided with an outer ring terminal 11 for connecting to the circuit of the fixed part. The crossbar 2 has a through cavity inside, and the wires of the photovoltaic panel 5 enter the through cavity through the port of the crossbar 2, and then are led out through the wire hole 12 located in the housing 6 and connected to the inner ring terminal 10. With this structure, no matter how the crossbar 2 rotates, the electrical continuity can be maintained through the relative rotation of the inner ring 8 and the outer ring 9, achieving 360-degree tilt angle flip without wire winding.

[0039] Specifically, the outer wall of the inner ring 8 and the inner wall of the outer ring 9 are respectively provided with conductive ring pads, and the two conductive ring pads slide in contact to achieve electrical connection during rotation.

[0040] In some embodiments, the angle adjustment mechanism includes a pitch angle reduction motor 13, a first gear, and a second gear 14; the pitch angle reduction motor 13 is connected to the first gear, and the second gear 14 is fixedly sleeved on the crossbar 2, and the first gear and the second gear 14 are meshed together.

[0041] Specifically, the pitch angle reduction motor 13 is connected to the first gear (not shown in the attached diagram), which meshes with the second gear 14. The second gear 14 is fixedly sleeved on the crossbar 2. Therefore, when the pitch angle reduction motor 13 is started, the rotation of the first gear drives the second gear 14 to rotate, thereby driving the crossbar 2 to adjust the pitch angle, realizing automated control of the pitch angle of the crossbar 2 and the photovoltaic panels and other components installed on it.

[0042] In some embodiments, the angle adjustment mechanism further includes a second conductive slip ring 15; the housing 6 is rotatable relative to the axis of the column 1; the second conductive slip ring 15 includes a sleeve 16 and an inner rod 17, the sleeve 16 is connected to the bottom plate of the housing 6, is coaxial with the column 1, and extends into the inner cavity of the column 1; the inner rod 17 is coaxially rotatably connected to the lower end of the sleeve 16 and is electrically connected to the sleeve 16; the inner rod 17 is connected to an inner column terminal 18, and the sleeve 16 is connected to a sleeve terminal 19; the sleeve terminal 19 is connected to an outer ring terminal 11 through a wire, and the wire of the inner column terminal 18 passes through the inner cavity of the column 1.

[0043] Specifically, the lower ends of the inner rod 17 and the sleeve 16 are coaxially rotatably connected, allowing relative rotation without affecting the electrical connection. An inner post terminal 18 is connected to the inner rod 17 to transmit electrical signals from inside the housing 6 or related components to the outside; a sleeve terminal 19 is connected to the sleeve 16, which is connected to the outer ring terminal 11 via a wire, ensuring continuity with the photovoltaic panel 5's wiring. When the housing 6 rotates, the sleeve 16 rotates accordingly, while the inner rod 17 remains stationary. The wires of the inner post terminal 18 pass through the inner cavity of the column 1, ensuring the continuity and stability of the electrical signal during rotation. This structural design achieves 360-degree rotation without wire entanglement.

[0044] In some embodiments, the angle adjustment mechanism includes an azimuth reduction motor 20, a third gear, and a fourth gear 21; the azimuth reduction motor 20 is connected to the third gear, and the fourth gear 21 is fixedly connected to the bottom plate of the housing 6, and the third gear and the fourth gear 21 are meshed together.

[0045] When the azimuth reduction motor 20 starts, the third gear starts to rotate under the drive of the motor and meshes with the fourth gear 21, thereby driving the fourth gear 21 and the housing 6 fixed thereto to rotate together, thus realizing the function of precise control of the azimuth angle of the light-collecting component 3.

[0046] In some embodiments, the heliostat further includes a controller 22, an elevation proximity switch 23, and an azimuth proximity switch 24; the wires of the elevation proximity switch 23 and the azimuth proximity switch 24 are respectively connected to the controller 22, and the wires of the controller 22 are connected to the sleeve terminal 19; the elevation proximity switch 23 cooperates with the stop of the second gear 14 for zero-position calibration of the elevation angle of the light-collecting component 3; the azimuth proximity switch 24 cooperates with the fourth gear 21 for zero-position calibration of the azimuth angle of the light-collecting component 3.

[0047] Specifically, the wires of the pitch proximity switch 23 and the azimuth proximity switch 24 are connected to the controller 22, forming a signal transmission path. Simultaneously, the wires of the controller 22 are connected to the sleeve terminal 19, communicating with the external electrical components of the heliostat. The pitch proximity switch 23 is designed to cooperate with the stop on the second gear 14 as a pitch zero-position start switch; similarly, the azimuth proximity switch 24 cooperates with the stop on the fourth gear 21 as an azimuth zero-position start switch. By resetting the heliostat daily and using the zero position detected by the proximity switches as the starting point for tracking, the cumulative error caused by long-term operation can be effectively reduced.

[0048] In some embodiments, the light-collecting component 3 includes a base frame, one side of which is fixedly connected to the crossbar 2; a plane mirror 4 is connected to one end face of the base frame; and a photovoltaic panel 5 is connected to the other end face of the base frame.

[0049] Specifically, the light-collecting module 3 uses a base frame as its supporting structure, with one side fixedly connected to the crossbar 2, ensuring stable installation and positioning of the light-collecting module 3. The planar mirror 4 is connected to one end face of the base frame to reflect sunlight and direct it in a specific direction, thereby improving the efficiency of light energy utilization. The photovoltaic panel 5 is connected to the other end face of the base frame, directly receiving and converting sunlight into electrical energy, achieving dual utilization of light energy. This design allows the light-collecting module 3 to simultaneously utilize the reflective function of the planar mirror and the power generation function of the photovoltaic panel, improving the overall performance of the system.
