[0020] The present invention has at least the following beneficial effects:

[0021] 1. Advantages of introducing natural fresh air by using the adaptive rotatable housing in the present invention:

[0022] (1) The housing that can be rotated at any angle automatically adapts to different natural wind directions, effectively improving the ventilation efficiency and meeting the requirements of different seasons, weather conditions and usage;

[0023] (2) The whole device utilizes the natural dynamic pressure difference to introduce and discharge air, without relying on electrical equipment. The air flow is realized through the natural air flow, which helps to capture the wind at zero energy cost, reduce energy consumption, lower the operation cost, and can also avoid generating noise and affecting the living comfort;

[0024] (3) Introducing fresh air helps to improve the indoor air quality, dilute the indoor pollutants, control the humidity, and provide a fresher indoor environment;

[0025] 2. Advantages of adopting the concentric double channels of fresh air and exhaust air by the mutual cooperation of structures such as the exhaust duct, intake duct, exhaust passage, intake passage, etc. set in the present invention:

[0026] (1) Avoid the pipelines from getting knotted during the rotation of the housing;

[0027] (2) The double channels in the intake and exhaust processes can not only achieve independent control of different areas, adjust the fresh air and exhaust air according to the needs of each area, reduce the indoor temperature and humidity fluctuations, improve the flexibility and adaptability of the system, but also effectively avoid the cross - contamination between the fresh air and the exhaust air, maintain the indoor environment in line with the health and hygiene standards, and reduce the risk of indoor air pollution;

[0028] (3) The slip - ring assembly is set to ensure that the fixed power lines and signal lines are in contact with the power lines and signal lines that need to rotate, avoiding the cable winding during the rotation of the housing;

[0029] (4) A heat recovery pipe can be installed between the intake duct and the exhaust duct as required. By transferring heat between the waste air and the fresh air, the energy reuse can be realized, cooling the fresh air in summer and preheating the fresh air in winter;

[0030] 3. Advantages of adopting the eccentric wind tail in the present invention:

[0031] (1) The wind - receiving area of the eccentric wind tail is large, so the wind pressure felt at the front end of the housing is not equal. The wind pressure perpendicular to the eccentric wind tail generates a wind pressure moment, which is convenient for the housing to rotate around the axis;

[0032] (2) The eccentric part in the eccentric wind tail can ensure that when the wind blows directly at the housing from the tail, the housing rotates normally, improving the rotation sensitivity;

[0033] 4. The present invention adopts the advantages of the integrated photovoltaic, energy storage, DC power supply and flexible load system:

[0034] (1) Photovoltaic power generation in the integrated photovoltaic, energy storage, DC power supply and flexible load system is a clean energy source that does not produce any pollutants, while reducing the consumption of the device from the main power supply, contributing to environmental protection;

[0035] (2) The combination of photovoltaic power generation and DC power distribution technology in the integrated photovoltaic, energy storage, DC power supply and flexible load system powers the control panel and cross-flow fans, reducing the consumption of the main power supply and making the entire system more efficient with less energy loss.

[0036] (3) The energy storage system in the integrated photovoltaic, energy storage, DC power supply and flexible load system can store excess electric energy for later use, thus reducing energy waste;

[0037] 5. Advantages of adopting the control panel:

[0038] (1) Real-time monitoring of the fresh air volume, exhaust air volume and indoor and outdoor air quality parameters, controlling the opening and closing angle of the inlet louvers, the switch and speed of the axial flow fan and the cross-flow fan in the room, realizing remote monitoring and operation of the overall fresh air system, and improving the system management integration;

[0039] (2) It can automatically execute the fresh air control strategy according to the predetermined algorithm and set parameters, realizing intelligent building fresh air management, and automatically making corresponding adjustments according to real-time factors such as indoor and outdoor environment and demand changes;

[0040] (3) Due to the automation and remote monitoring functions of the system, the need for manual intervention can be reduced, and the labor costs for maintenance and operation can be lowered.

[0041] 6. Advantages of adopting the axial flow fan and cross-flow fan:

[0042] (1) It can increase the mechanical ventilation volume when the natural ventilation volume is insufficient, ensuring a stable supply of fresh air volume;

[0043] (2) The axial flow fan has the characteristics of high air volume and low pressure loss. Installed on the roof, it is beneficial to supplement the air volume, has relatively little noise interference to the room, has a relatively simple structure, no complex impeller structure, relatively low maintenance cost, and has little impact on the circulation of natural wind when the fan is not started;

[0044] (3) The cross-flow fan has a small height or thickness, which is beneficial to reducing the thickness of the air outlet; the axial length is not restricted, and the length of the cross-flow blades can be arbitrarily selected according to different usage requirements; the air flow passes through the cross-flow blades, and is affected by the force of the blades twice, so the air flow can reach a long distance; there is no turbulent flow, and the air outlet is uniform; the noise is small, the operating power is low, and it can effectively promote the indoor air in the room, forming a good air circulation, avoiding dead corners in the room, and improving the air uniformity.

[0045] Of course, it is not necessary for any product implementing the present invention to achieve all of the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0057] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0058] Please refer to Figure 1 -9. The present invention provides a technical solution: a dual-channel adaptive natural fresh air device integrating solar photovoltaic, including a building main body 1. A circulation pipeline unit 2 is installed on the side wall of the building main body 1. An adapter unit 3 is installed on the circulation pipeline unit 2. A housing 4 is rotatably connected to the adapter unit 3. An air inlet channel 5 and an air outlet channel 6 are respectively arranged inside the housing 4. The air inlet channel 5 and the air outlet channel 6 are arranged in a concentric double-pipe layout, and the air inlet channel 5 and the air outlet channel 6 are mutually communicated with the circulation pipeline unit 2 along the air flow circulation direction.

[0059] Air inlet assemblies 7 and air outlet assemblies 8 are respectively opened on the side walls of the air inlet channel 5 and the air outlet channel 6. An eccentric air tail 9 is installed on one side of the housing 4 close to the air outlet assembly 8, and the eccentric air tail 9 is located above the air outlet assembly 8.

[0060] Regarding the technical solution of this embodiment, as Figure 1-2 shown, the circulation pipeline unit 2 includes an air inlet pipe 21 installed on one side of the building main body 1 and an air outlet pipe 22 installed on the other side of the building main body 1. The bottom end of the air inlet pipe 21 is located at the lower part of the building main body 1, and the bottom end of the air outlet pipe 22 is located at the upper part of the building main body 1. The two are distributed on opposite sides of the building main body 1, which is beneficial to air circulation. Cross-flow fans 23 are installed at the ends where the air inlet pipe 21 and the air outlet pipe 22 are connected and communicated with the building main body 1. During actual use, natural wind enters from the air inlet assembly 7 and enters the interior of the building main body 1 through the air inlet pipe 21. Then, the polluted air in the room will be discharged to the outside along the air outlet pipe 22 and the air outlet assembly 8 under the action of negative pressure and thermal pressure. In this way, the natural circulation flow of indoor and outdoor air in the building main body 1 can be realized. It should be noted that, through the provided cross-flow fans 23, it is convenient to assist in air inlet or air outlet when the natural air volume is insufficient.

[0061] As Figure 1 、 Figure 2 、 Figure 6As shown in the figure, the connection unit 3 includes a fixing member 31, a flat thrust ball bearing 32 and a slip ring assembly 33 installed at the tops of the air inlet pipe 21 and the air outlet pipe 22. For the technical solution of this embodiment, the fixing member 31 is arranged in a cylindrical shape. The air outlet pipe 22 is located at the center of the fixing member 31, and the air inlet pipe 21 is located on one side of the fixing member 31. The air inlet channel 5 and the air outlet channel 6 are concentric double pipes and can rotate together with the housing 4. By providing the connection unit 3, during the rotation of the housing 4, the air inlet pipe 21 and the air outlet pipe 22 become two independent pipes with a non-concentric circle relationship, and the air inlet pipe 21 communicates with the air inlet channel 5, and the air outlet pipe 22 communicates with the air outlet channel 6, which is convenient to always maintain a double-pipe double-flow direction during the entire air supply and exhaust process, avoid air cross-contamination, and is conducive to zonal control.

[0062] Furthermore, the tops of the air inlet pipe 21 and the air outlet pipe 22 are rotatably connected to the housing 4 through flat thrust ball bearings 32. When the wind blows from the outside to the housing 4, the air flow will blow to the provided eccentric air tail 9, which can cause the housing 4 to rotate continuously. When the housing 4 rotates, it will drive the air in the center of the air outlet pipe 22 to generate negative pressure under the action of centrifugal force, so that the indoor air rushes to the air outlet pipe 22 due to the pressure difference and then is discharged outdoors through the air outlet assembly 8, thus achieving the purpose of accelerating the indoor air flow. It should be noted that axial flow fans 24 are installed inside the air inlet pipe 21 and the air outlet pipe 22 near the housing 4. By providing the axial flow fans 24, it is convenient to assist in air inlet or exhaust when the natural air volume is insufficient.

[0063] Furthermore, a heat recovery pipe can be installed between the air inlet pipe and the air outlet pipe as required, and by transferring heat between the waste air and the fresh air, the reuse of energy can be realized, cooling the fresh air in summer and preheating the fresh air in winter.

[0064] Furthermore, the number of flat thrust ball bearings 32 is set to two. The two bearings are in a concentric circle relationship. One is fixed to the housing 4, and the other is fixed to the air outlet channel 6. The flat thrust ball bearing 32 includes an inner ring 321, a steel ball assembly 322 and an outer ring 323. The slip ring assembly 33 is installed on the inner wall of the inner ring 321 through a connecting rod, and the slip ring assembly 33 is installed at the center of the air outlet pipe 22. By using the provided flat thrust ball bearings 32, it is convenient to always maintain a connection with the air inlet pipe 21 and the air outlet pipe 22 when the housing 4 rotates, and to make the air inlet process and the air outlet process non-interfering.

[0065] Furthermore, the slip ring assembly 33 includes a rotating shaft 333, a stator 331, a rotor 332, a slip ring stopper 334, a stop pin 335, and power and signal lines 336. The stator 331 is internally rotatably connected to the rotor 332. The rotating shaft 333 is mounted at the center of the rotor 332. The slip ring stopper 334 is connected to the stator 331. The slip ring stopper 334 is mounted with a stop pin 335. The slip ring stopper 334 and the stop pin 335 together fix the slip ring assembly 33 to the connecting rod.

[0066] The power line and signal line 336 are installed in the stator 331 and the rotor 332. One end of the exposed interface is connected to the line in the stator 331, and the other end is connected to the line in the rotor 332. The slip ring assembly 33 provided can ensure that the fixed power line and signal line maintain contact with the power line and signal line that need to rotate, thereby avoiding cable entanglement during the rotation of the shell 4, which affects use.

[0067] like Figure 4 As shown, the air inlet assembly 7 includes an electric shutter 71 installed at the air inlet position. The electric shutter 71 is convenient for controlling the opening or closing of the air inlet. A first protective net 72 is installed on the inner side of the electric shutter 71 to prevent external impurities such as flying insects and leaves from entering the air inlet. A HEPA filter 73 is installed on the inner wall of the first protective net 72. The HEPA filter 73 can filter the pollutant particles in the air. A negative ion assembly 74 is installed on the inner side of the HEPA filter 73. According to the technical solution of this embodiment, the negative ion assembly 74 is set as a negative ion generator. When used in combination, the negative ions generated can be brought into contact with particulate matter in the air (such as dust, bacteria, viruses, pollen, smoke, etc.), which can make these particles charged. These charged particles gather together due to the attraction of the charge to form larger particles, which eventually settle to the ground or are adsorbed by electrostatic dust collecting plates. In addition, negative ions also have the effect of sterilization and disinfection. They can interact with the bioelectric potential on the surface of the cell membrane of bacteria and viruses, change their biological activity, and thus achieve a killing effect; negative ions can also combine with harmful gas molecules in the air (such as formaldehyde, benzene, etc.), and convert them into harmless substances such as water and carbon dioxide by seizing electrons from these molecules.

[0068] High-efficiency air filters (HEPA filters 73) are mainly used to capture dust particles larger than 0.5 μm and various suspended matter. The air purifier is mainly composed of a filter element and a housing 4. The basic requirements are high filtration efficiency, low flow resistance, and long-term continuous use to reduce the cost of later consumables.

[0069] Regarding the technical solution of this embodiment, Figure 5As shown, the air outlet assembly 8 includes a fixed louver 81 installed on the air outlet. A second protective net 82 is installed inside the fixed louver 81. By means of the provided second protective net 82, it is convenient to prevent impurities such as flying insects and leaves from the outside from entering the air outlet.

[0070] Regarding the technical solution of this embodiment, as Figure 8 shown, the eccentric air tail 9 includes an air tail housing 91 fixed to the side wall of the housing 4. One side of the inner wall of the air tail housing 91 is fixedly connected with an eccentric member 92, and the surface of the eccentric member 92 is set as a special-shaped arc surface. When the natural wind blows directly at the housing 4 from the back, the housing 4 can rotate normally through the air tail housing 91 and the eccentric member 92, avoiding the reverse flow of wind from the air outlet.

[0071] Regarding the technical solution of this embodiment, as Figure 1-2 shown, the whole device further includes a solar photovoltaic panel and a storage battery. The solar photovoltaic panel is installed on the outer surface of the housing 4, and the storage battery is installed indoors. The wire enters the room from the exhaust duct 22. Combining with the photovoltaic energy storage direct current and flexible interaction (PEDF) system, the energy absorbed by the solar photovoltaic panel forms a direct current. Part of it is supplied to the cross-flow fan 23, the wind speed sensor 10, the differential pressure sensor 11, the temperature and humidity sensor 12, the carbon dioxide sensor 13, the dust sensor 15, the formaldehyde & VOC sensor 16 and the control panel 14, and the other part is stored in the storage battery for supplementary power supply when the solar light intensity is insufficient.

[0072] Photovoltaic energy storage direct current and flexible interaction (PEDF) is the abbreviation of four technologies, namely solar photovoltaic (Photovo l ta i c), energy storage (Energy storage), direct current distribution (D i rect current) and flexible interaction (F l ex i b i l ity) applied in the building field. Photovoltaic energy storage direct current and flexible interaction is an important pillar for the development of zero-carbon energy and is conducive to directly consuming wind power and photovoltaic power.

[0073] Regarding the technical solution of this embodiment, as Figure 9a and Figure 9bAs shown in the figure, wind speed sensors 10, differential pressure sensors 11, and temperature and humidity sensors 12 are installed above the eccentric air tail 9, inside the air inlet pipe 21 and the air outlet pipe 22. Temperature and humidity sensors 12, carbon dioxide sensors 13, dust sensors 15, and formaldehyde & VOC sensors 16 are also installed inside the building main body 1. A control panel 14 is installed inside the building main body 1. The control panel 14 is electrically connected to the wind speed sensors 10, differential pressure sensors 11, temperature and humidity sensors 12, carbon dioxide sensors 13, dust sensors 15, formaldehyde & VOC sensors 16, electric louvers 71, axial flow fans 24, and cross-flow fans 23. The control panel 14 can sense the wind speed sensors 10, differential pressure sensors 11, temperature and humidity sensors 12, carbon dioxide sensors 13, indoor dust sensors 15, and formaldehyde & VOC sensors 16, and control the opening and closing angle of the electric louvers 71 at the air inlet, and the startup and rotation speed of the axial flow fans 24 and cross-flow fans 23. When it senses that the indoor air quality is low (the concentration of carbon dioxide, dust, formaldehyde & VOC, etc. is too high) or the wind speed (air volume) in the air inlet pipe 21 and the air outlet pipe 22 is too low, it can automatically or manually increase the opening and closing angle of the electric louvers 71, start the axial flow fans 24 and cross-flow fans 23, and increase the rotation speed of the axial flow fans 24 and cross-flow fans 23 when necessary.

[0074] It should be noted that for the technical solution of this embodiment, the control panel 14 is set as a PLC controller, a programmable logic controller (Programmable Logic Controller, PLC), a digital arithmetic controller with a microprocessor for automatic control, which can load control instructions into the memory at any time for storage and execution. The programmable controller is composed of functional units such as a CPU, instruction and data memory, input / output interface, power supply, and digital-to-analog conversion. The early programmable logic controllers only had the function of logical control, so they were named programmable logic controllers. Later, with continuous development, these originally simple computer modules have various functions including logical control, timing control, analog control, multi-machine communication, etc.

[0075] The working principle and process of the present invention are as follows: First, the external natural wind enters from the air inlet assembly 7. After the air is purified by the first protective net 72, the HEPA filter 73 and the negative ion assembly 74, the air will enter the air inlet passage 5 and enter the interior of the building main body 1 through the air inlet pipe 21. Then, the polluted indoor air will be discharged to the outside through the exhaust pipe 22 and the exhaust port assembly 8 under the action of negative pressure and thermal pressure. In this way, the natural circulation of air inside and outside the building main body 1 can be realized. When the external natural wind volume is insufficient, the cross-flow fan 23 and the axial flow fan 24 are provided to facilitate mechanical auxiliary air intake or exhaust. And when the external wind blows directly against the housing 4, the air flow will blow towards the eccentric wind tail 9 provided, which can make the housing 4 rotate continuously. When the housing 4 rotates, it will drive the air in the center of the exhaust pipe 22 to generate negative pressure under the action of centrifugal force, so that the indoor air will rush towards the exhaust pipe 22 due to the pressure difference and then be discharged to the outside through the exhaust port assembly 8, so as to achieve the purpose of accelerating the indoor air flow. This is convenient for reducing the power demand, with relatively low energy consumption, helping to reduce energy consumption and operating costs. And the rotating housing 4 can also automatically adapt to different natural wind directions, effectively improving the ventilation efficiency and meeting the usage requirements in different seasons and weather conditions.
