Description

Technical Field

[0001] This utility model relates to the field of heliostat technology, specifically a heliostat solar drying device. Background Technology

[0002] Solar drying technology is an environmentally friendly method that uses solar energy to dehydrate materials. It boasts advantages such as energy saving, low carbon emissions, and sustainability. This technology converts solar energy into heat energy for drying materials through processes like heat collection and photothermal conversion, and is widely used in agricultural products, food, and medicinal materials. Currently, heliostat technology is mainly applied in solar thermal power generation systems, precisely tracking the sun's position to reflect sunlight onto a heat collection tower, achieving highly efficient energy conversion.

[0003] However, in the drying field, traditional equipment mostly relies on fixed power grids or independent power generation equipment, which poses a problem of power supply difficulties in remote areas or field operation environments. The high-efficiency energy supply characteristics of heliostat technology have not been fully utilized. In addition, the uneven distribution of hot air in traditional drying systems can easily cause local overheating of materials or incomplete drying, affecting drying efficiency and quality. Therefore, a heliostat solar drying device is needed to solve the existing shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing methods that directly combine heliostat power supply with drying devices, and to provide a heliostat solar drying device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heliostat solar drying device includes a drying cylinder, a support plate fixedly connected to the top of the drying cylinder, a ring rail fixedly connected to the top of the support plate, a slip ring slidably connected to the ring rail, several heliostats fixedly connected to the top of the slip ring, a converter fixedly connected to the top of the slip ring, a protective cover fixedly connected to the inner side of the slip ring, an energy storage device fixedly connected to the protective cover, and the energy storage device electrically connected to the converter, a control component provided on the support plate, and the control component fixedly connected to the slip ring, a drying component provided inside the drying cylinder, and several storage trays provided inside the drying cylinder.

[0007] Furthermore, the control component includes a gear ring, a gear, and a rotating shaft. The gear ring is sleeved on the outside of the slip ring and is fixedly connected to the slip ring. The rotating shaft passes through the axis of the gear and is fixedly connected to the gear. The gear is movably connected to the support plate through the rotating shaft and meshes with the gear ring.

[0008] Furthermore, a servo motor is fixedly connected to the bottom end of the tray, and the output end of the servo motor is fixedly connected to the bottom end of the rotating shaft. The servo motor is electrically connected to the energy storage device.

[0009] Furthermore, an air guide plate is fixedly connected inside the drying cylinder, and a rotating column is fixedly connected at the axis of the air guide plate. The rotating column passes through the axis of the storage tray and is fixedly connected to the storage tray.

[0010] Furthermore, the drying assembly includes fan blades, a heating plate, and drying components. A support frame is fixedly connected inside the drying cylinder. The fan blades are movably connected to the support frame via a rotating shaft. The bottom end of the rotating shaft of the fan blades is fixedly connected to the top end of the rotating column via a gearbox. The heating plate is fixedly connected to the inner side of the drying cylinder and is located at the bottom end of the fan blades. The drying components are arranged in a circular array, and the top of the drying components is fixedly connected to the air guide plate.

[0011] Furthermore, a second servo motor is fixedly connected to the top of the support frame, and the output end of the second servo motor is fixedly connected to the rotating shaft of the fan blade.

[0012] Furthermore, the top of the drying component has an air inlet located at the top of the air guide plate, and the top of the drying component has an air outlet facing the storage tray.

[0013] Furthermore, the air guide plate has several ventilation slots, which are arranged in a circular array.

[0014] Compared with existing technologies, this heliostat solar drying device has the following advantages:

[0015] I. This utility model, through its control components, drives a servo motor via an energy storage device, causing the rotating shaft to rotate. This causes the gear to rotate on the support plate. Since the gear meshes with the gear ring, it drives the slip ring to rotate on the slide rail, thereby controlling the rotation of the heliostat and converter as a whole. This allows the heliostat to adapt to changes in the angle of the sun, which helps the heliostat reflect sunlight at different angles to the converter, thus improving the adaptability of the drying device to different environments.

[0016] Second, through the drying components set up in this utility model, a portion of the hot air enters the interior of the drying cylinder vertically from the ventilation slot, while another portion of the hot air is turned by the surface of the air guide plate and enters the interior of the drying component. Finally, it is blown horizontally from the air outlet of the drying component into the interior of the drying cylinder, thereby drying the material on the tray. This is beneficial for drying the material from various angles, improving drying efficiency, and avoiding direct hot air blowing in one direction.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, the technical solution of this utility model is as follows: a heliostat solar drying device, including a drying cylinder 1, which is used for drying materials. The drying cylinder 1 has an opening on its outer side, and an arc-shaped sealing door is provided at the opening. A support plate 2 is fixedly connected to the top of the drying cylinder 1, and a ring rail 3 is fixedly connected to the top of the support plate 2. A slip ring 4 is slidably connected to the ring rail 3. Several heliostats 5 are fixedly connected to the top of the slip ring 4. The heliostat 5 consists of a heliostat and a multi-axis adjustment mechanism, which enables the heliostat to adjust its pitch angle. A converter 6 is fixedly connected to the top of the slip ring 4, which is used to convert solar energy into electrical energy. The converter 6 is a high-concentration photovoltaic cell module, preferably a multi-junction gallium arsenide cell (such as Azur Space 3G30C or Spectrolab C3MJ). It receives the sunlight reflected by the heliostat 5 and directly converts it into electrical energy. The output end is connected to an energy storage device 8. The photovoltaic cell module needs to be equipped with a heat dissipation substrate (such as a copper heat pipe or a micro fan) to maintain the operating temperature below 80°C. A protective cover 7 is fixedly connected to the inner side of the slip ring 4. An energy storage device 8 is fixedly connected to the protective cover 7 to store electrical energy and power the electrical equipment. The energy storage device 8 is electrically connected to the converter 6. A control component 9 is set on the tray 2 and is fixedly connected to the slip ring 4. A drying component 10 is set inside the drying cylinder 1, and several storage trays 11 are set inside the drying cylinder 1. The storage trays 11 are used for placing materials. The solar energy is concentrated onto the converter 6 by the heliostat 5 at the top of the slip ring 4, thereby converting solar energy into electrical energy and storing the electrical energy inside the energy storage device 8. The energy storage device 8 powers the servo motor 12, the servo motor 2 15, and the heating plate 1002.

[0026] like Figure 1 and Figure 4 As shown, the control component 9 includes a gear ring 901, a gear 902, and a rotating shaft 903. The gear ring 901 is sleeved on the outside of the slip ring 4 and is fixedly connected to the slip ring 4. The rotating shaft 903 passes through the axis of the gear 902 and is fixedly connected to the gear 902. The gear 902 is movably connected to the support plate 2 through the rotating shaft 903 and meshes with the gear ring 901. A servo motor 12 is fixedly connected to the bottom end of the support plate 2, and the output end of the servo motor 12 is fixedly connected to the bottom end of the rotating shaft 903. The servo motor 12 is electrically connected to the energy storage device 8.

[0027] The servo motor 12 is driven by the energy storage device 8, which drives the rotating shaft 903 to rotate, causing the gear 902 to rotate on the support plate 2. Since the gear 902 meshes with the gear ring 901, it drives the slip ring 4 to rotate on the slide rail, thereby controlling the rotation of the heliostat 5 and the converter 6 as a whole. This allows the heliostat 5 to adapt to the changing angle of the sun, which helps the heliostat 5 to reflect sunlight at different angles to the converter 6, thereby improving the adaptability of the drying device to working in different environments.

[0028] like Figure 1 and Figure 5 As shown, a guide plate 13 is fixedly connected inside the drying cylinder 1. A rotating column 14 is fixedly connected to the axis of the guide plate 13. The rotating column 14 passes through the axis of the storage tray 11 and is fixedly connected to the storage tray 11. The drying assembly 10 includes a fan blade 1001, a heating plate 1002, and a drying component 1003. A support frame 16 is fixedly connected inside the drying cylinder 1. The fan blade 1001 is movably connected to the support frame 16 via a rotating shaft. The bottom end of the rotating shaft of the fan blade 1001 is fixedly connected to the top end of the rotating column 14 via a gearbox. The heating plate 1002 is fixedly connected to the inner side of the drying cylinder 1 and is heated... The hot plate 1002 is located at the bottom of the fan blade 1001. The drying components 1003 are arranged in a circular array, and the top of the drying components 1003 is fixedly connected to the air guide plate 13. The top of the support frame 16 is fixedly connected to the second servo motor 15, and the output end of the second servo motor 15 is fixedly connected to the rotating shaft of the fan blade 1001. The top of the drying component 1003 has an air inlet, and the air inlet is located at the top of the air guide plate 13. The top of the drying component 1003 has an air outlet, and the air outlet faces the tray 11. Several ventilation slots 17 are opened on the air guide plate 13, and the ventilation slots 17 are arranged in a circular array.

[0029] The servo motor 15 is started, driving the fan blade 1001 to rotate at high speed. The heating plate 1002 is controlled to convert electrical energy into heat. The hot air generated by the rotation of the fan blade 1001 is blown onto the air guide plate 13. Part of the hot air enters the interior of the drying cylinder 1 vertically from the ventilation slot 17, while the other part of the hot air is turned by the surface of the air guide plate 13 and enters the interior of the drying component 1003. Finally, it is blown horizontally from the air outlet of the drying component 1003 into the interior of the drying cylinder 1, thereby drying the material on the tray 11. This is beneficial for drying the material from various angles, improving drying efficiency, and avoiding direct hot air blowing in one direction.

[0030] The working principle is as follows:

[0031] In operation, firstly, the sun's light is concentrated onto the converter 6 via the heliostat 5 at the top of the slip ring 4, thus converting solar energy into electrical energy, which is then stored inside the energy storage unit 8. The energy storage unit 8 powers the servo motor 12, the servo motor 15, and the heating plate 1002. Servo motor 12 is then activated, causing the rotating shaft 903 to rotate, which in turn causes the gear 902 to rotate on the support plate 2. Since the gear 902 meshes with the gear ring 901, it drives the slip ring 4 to rotate on the slide rail, thereby controlling the rotation of the heliostat 5 and the converter 6 as a whole, thus achieving heliostating. Device 5 can adapt to changes in the angle of the sun; it starts the servo motor 15, drives the fan blade 1001 to rotate at high speed, and controls the heating plate 1002 to convert electrical energy into heat. The hot air generated by the rotation of the fan blade 1001 is blown onto the air guide plate 13. Part of the hot air enters the interior of the drying cylinder 1 vertically from the ventilation slot 17, and the other part of the hot air is turned by the surface of the air guide plate 13 and enters the interior of the drying component 1003. Finally, it is blown horizontally from the air outlet of the drying component 1003 into the interior of the drying cylinder 1, thereby drying the material on the tray 11.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
