[0040] Please refer to Figure 1 and Figure 2 The present application provides a weather detection device, including an insulating body 100, a radiation cooling film 200, a first temperature sensor 300 and a control module 12. A first cavity 110 is formed inside the insulating body 100. The material of the insulating body 100 can be rock wool, silica gel, foamed polyurethane foam, etc.
[0041] The heat-insulating body 100 is also provided with a first light-transmitting port 111 connected to the first cavity 110. The radiation cooling film 200 is arranged inside the first cavity 110 and directly opposite to the first light-transmitting port 111. The radiation cooling film 200 is used to emit far-infrared light. The first temperature sensor 300 is arranged on the side of the radiation cooling film 200 facing away from the first light-transmitting port 111 and sends out first temperature information; the control module 12 is electrically connected to the first temperature sensor 300 and is used to obtain ambient temperature information. The control module 12 analyzes the current weather conditions according to the difference between the first temperature information and the ambient temperature information. Figure 2 , the control module 12 can Figure 2 The control module 12 in the apparatus may acquire and analyze the temperature information, or the temperature information may be transmitted to an external analysis device and acquired and analyzed in the external analysis device.
[0042] The radiation cooling film 200 is composed of polymer materials and inorganic functional materials, and is used to emit far-infrared light. The specific band is far-infrared light that passes through the atmospheric transmission window band (8μm-13μm). In this way, heat can be continuously and efficiently transferred to the cold source in outer space, while being able to reflect most of the solar radiation energy and minimize the absorption of solar heat. When detecting the weather, the radiation cooling film 200 can be used to emit far-infrared light, which radiates heat into the deep space through the first light-transmitting port 111. Therefore, the thermal temperature of the first radiation cooling film 200 is low, which can reduce the temperature inside the first cavity 110. Secondly, the radiation cooling film 200 can also reflect the sunlight that is irradiated into the first cavity 110 through the first light-transmitting port 111 out of the first cavity 110.
[0043] The first temperature sensor 300 is arranged on the side of the radiation cooling film 200 facing away from the first light transmission port 111, so the first temperature information measured is the temperature in the first cavity 110 after the radiation cooling film 200 radiates from deep space and reflects most of the sunlight. The ambient temperature is the actual temperature without considering direct sunlight and deep space radiation. Therefore, the difference between the first temperature information and the ambient temperature information can reflect the weather conditions. The following difference is calculated by subtracting the ambient temperature information from the first temperature information.
[0044] If the weather is sunny and there are few clouds in the sky, during the day, the radiation cooling film 200 will reflect part of the incident sunlight and emit far-infrared light into the deep space, reducing the temperature rise of the first cavity 110 under solar radiation. Since the solar radiation power is large, the measured first temperature information is still significantly higher than the ambient temperature, and there will be a large difference between the two. At night, the radiation cooling film 200 will also emit far-infrared light into the deep space. Since there is no solar radiation, the first temperature information will be significantly lower than the ambient temperature information. Given that the radiation power in the deep space is small, the difference between the two is smaller than that during the day.
[0045] If it is cloudy or rainy, and the sky is covered with cumulus clouds, during the day, the first cavity 110 receives less solar radiation, and the far-infrared light emitted by the radiation cooling film 200 is difficult to penetrate the clouds, and the difference between the first temperature information and the ambient temperature information is small. At night, the radiation amount of the radiation cooling film 200 is still small. Although the first temperature information may be lower than the ambient temperature information, the difference is small, or even close to 0.
[0046] If the weather is cloudy, the solar radiation received by the first cavity 110 during the day and the far infrared light emitted by the radiation cooling film 200 during the day or at night will be affected by the clouds in the sky. If the clouds cover the sky, the difference between the first temperature information and the ambient temperature information is small. If the clouds in the sky are dispersed, the difference between the first temperature information and the ambient temperature information is large. Therefore, in cloudy weather, the difference between the first temperature information and the ambient temperature information will fluctuate greatly due to the influence of clouds.
[0047] Therefore, the present application can judge the current weather conditions based on the difference between the first temperature information and the ambient temperature information, and then judge whether it is suitable for deep space radiation cooling and solar energy heat collection. For example, if the first temperature information is detected to be significantly higher than the ambient temperature and the difference is relatively large, it means that the current weather is most likely a clear daytime, which is suitable for deep space radiation cooling and solar energy heat collection. If the first temperature information is detected to be significantly lower than the ambient temperature information and has a certain difference, it means that the current weather is most likely a clear night, which is suitable for deep space radiation cooling. When it is detected that the temperature difference is not significant and tends to 0, it means that the current weather is most likely cloudy or rainy, which is not suitable for solar energy heat collection and deep space radiation cooling. When it is detected that the temperature difference fluctuates greatly, it means that the current weather is most likely cloudy, which is suitable for solar energy heat collection and deep space radiation cooling during the day and suitable for deep space radiation cooling at night. Therefore, the weather detection device of the present application can detect weather conditions and provide guidance for solar energy heat collection and deep space radiation cooling.
[0048] In one embodiment, reference Figure 1 A second cavity 120 is formed inside the heat-insulating body, and a second light-transmitting port 121 connected to the second cavity 120 is provided; a radiation-absorbing film 400 is provided inside the second cavity 120, and the radiation-absorbing film 400 is directly opposite to the second light-transmitting port 121 and is used to absorb solar radiation. A second temperature sensor 500 is also provided inside the second cavity 120, and the second temperature sensor 500 is provided on the side of the radiation-absorbing film 400 facing away from the second light-transmitting port 121, and sends out second temperature information; the control module 12 is also electrically connected to the second temperature sensor 500, and the control module 12 also analyzes the current weather conditions according to the difference between the second temperature information and the first temperature information, and the difference between the second temperature information and the ambient temperature information.
[0049] During the day, both the radiative absorption film 400 and the radiative cooling film 200 absorb sunlight, reflect sunlight, and radiate to deep space simultaneously. At night, both the radiative absorption film 400 and the radiative cooling film 200 radiate to deep space. However, between the radiative absorption film 400 and the radiative cooling film 200, the radiative absorption film 400 has a high solar radiation absorption rate, a low solar radiation reflectivity, and a low deep space radiation rate. While the radiative cooling film 200 has a low solar radiation absorption rate, a high solar radiation reflectivity, and a high deep space radiation rate. Therefore, according to the weather conditions, the differences between the second temperature information and the first temperature information, and between the second temperature information and the ambient temperature information will also show differences and are closely related to the weather conditions. There is a logical relationship among the first temperature information, the second temperature information, and the ambient temperature information in this embodiment. Once it is recognized that the logical relationship among the three does not conform during use, it can be prompted that the device may have a fault, or there is garbage blocking the transmissive layer, and maintenance or repair is required. Further, in this embodiment, the measured second temperature information can be used as supplementary data to supplement the measurement result of the first temperature information, making the measured weather conditions more accurate. The radiative absorption film 400 can be a black solar radiation absorption film.
[0050] The analysis of the detection results of the weather detector can be that the first temperature information is represented by TA, the second temperature information is represented by TB, and the ambient temperature information is represented by TC. D1 = (TA - TC), D2 = (TB - TC), D3 = (TA - TB).
[0051] When TA > TC, at the same time TB > TC, and D1 and D2 are large, and D3 is also large, it indicates that the current weather is a clear day with few clouds in the sky, suitable for solar energy collection.
[0052] When TA > TC, at the same time TB > TC, and D1 and D2 are large and fluctuating, and D3 is large and fluctuating, it indicates that the current weather is a cloudy day, and more solar radiation can be received, suitable for solar energy collection.
[0053] When TA > TC, at the same time TB > TC, and D1 and D2 are small, and D3 is small, it indicates that it is daytime and the weather is cloudy or rainy. The sky is covered by clouds, not suitable for solar energy collection and deep space radiative cooling.
[0054] When TA < TC, at the same time TB < TC, and D1 and D2 are large, and D3 is large, it indicates that it is night, and the weather is a clear night or a cloudy night, suitable for deep space radiative cooling.
[0055] When TA < TC, at the same time TB < TC, and D1 and D2 are small, and D3 approaches 0, it indicates that it is a cloudy night or a rainy night, not suitable for deep space radiative cooling.
[0056] The weather detector can analyze the current weather conditions based on the above logic and guide solar thermal collection and deep space radiation cooling. The specific numerical comparison of D1, D2, and D3 can be repeatedly verified in the test, or the learning system can be used to analyze the appropriate value and design the comparison threshold in the control module.
[0057] In one embodiment, the first light-transmitting port 111 is provided with a first transmission layer 111a, and the second light-transmitting port 121 is provided with a second transmission layer 121a, and the far-infrared light transmittance of the second transmission layer 121a is lower than the far-infrared light transmittance of the first transmission layer 111a. The far-infrared light transmittance here may specifically refer to the infrared light transmittance of 8μm-13μm. The structure of the present application can further increase the deep space radiation cooling in the first cavity 110 and reduce the deep space radiation cooling in the second cavity 120. The difference between the first temperature information and the second temperature information is enlarged, thereby making the measurement result more obvious and the weather detection more accurate. The first transmission layer 111a and the second transmission layer 121a can also both use film materials with higher far-infrared transmittance, specifically polyethylene film (PE).
[0058] In another embodiment, the first transmission layer and the second transmission layer are polyethylene layers, and the polyethylene layers have high far-infrared light transmittance.
[0059] In one embodiment, the first transmission layer 111a and the second transmission layer 121a have a hollow structure inside. Since the thermal conductivity of air is lower than that of solids, the hollow structure can effectively reduce heat conduction, convection heat transfer and radiation heat loss. Therefore, in this embodiment, the first transmission layer and the second transmission layer are designed as hollow structures, which can better insulate the first cavity 110 and the second cavity 120 from the external environment. For the first transmission layer 111a, the specific hollow structure can be a hollow layer in the same extension direction as the first transmission layer 111a, or a plurality of hollow cavities between the first transmission layer 111a, etc.
[0060] In one embodiment, reference Figure 1 and Figure 2The heat-insulating body 100 includes a light-facing surface 101, a first cavity 110 and a second cavity 120 are arranged side by side along the light-facing surface 101, and a first light-transmitting port 111 and a second light-transmitting port 121 are located on the light-facing surface. The light-facing surface 101 is the side of the heat-insulating body 100 facing the sunlight. The heat-insulating body 100 is also formed with a third cavity 130, and a vent 131 connected to the third cavity 130, the vent 131 is connected with a shading member 132, and the shading member 132 is located on the side of the vent 131 close to the light-facing surface 101. A third temperature sensor 600 is arranged inside the third cavity 130, and the third temperature sensor 600 is electrically connected to the control module 12 and is used to detect ambient temperature information. The first cavity 110 and the second cavity 120 are arranged side by side on the light-facing surface 101, which can ensure that the first light-transmitting port 111 and the second light-transmitting port 121 are in the same lighting environment, and the variables are controlled to make the measured weather conditions more accurate.
[0061] Furthermore, the third cavity 130 has a third temperature sensor 600 built in, and the third cavity 130 ensures that the temperature in the third cavity 130 is consistent with the ambient temperature through the vent 131. The light from the sun shining on the light-facing surface 101 can be blocked by the shading member 132 to prevent the sun's rays from raising the temperature inside the third cavity 130. The above structure can ensure that the ambient temperature measured by the third temperature sensor 600 is more accurate. The ambient temperature is measured in real time through the third cavity 130, and the first temperature information, the second temperature information and the ambient temperature information are all measured at the same time and at the same place, and the difference between them can more accurately reflect the current weather conditions in real time.
[0062] In one embodiment, reference Figure 1 The third cavity 130 is located on the side of the first cavity 110 and the second cavity 120 facing away from the light-facing surface 101, and the shading member 132 is tilted away from the light-facing surface. The third cavity 130 faces away from the light-facing surface 101 to avoid direct sunlight. The shading member 132 is tilted away from the light-facing surface 101 to block part of the diffusely reflected sunlight, further reducing the temperature rise of the third cavity 130 due to the sunlight. Specifically, multiple vents 131 and shading members 132 can be set on both sides of the third cavity 130.
[0063] In one embodiment, the radiation cooling film 200 is an aluminum foil coated with a titanium dioxide film. Titanium dioxide is a white material that can reflect most of the sunlight, and the aluminum foil coated with a titanium dioxide film has a high far-infrared light emission capability. And / or, the radiation absorbing film 400 is an aluminum foil coated with a black paint film, which can absorb a large amount of sunlight. The film material selected in this embodiment is easy to obtain, simple to make, and can effectively perform deep space radiation cooling and absorb solar energy.
[0064] In one embodiment, the first transmission layer 111a is a polyethylene film (PE), which has a high far-infrared light transmittance. The second transmission layer 121a is a polycarbonate plate or a glass plate, which has a low far-infrared light transmittance. The deep space radiation difference can be enlarged, and the materials used are common materials with low cost.
[0065] In one embodiment, please refer to Figure 3 The weather detection device also includes a dust-blocking film 700, which is replaceable and covers the first light-transmitting port 111 and the second light-transmitting port 121. When the weather detection device is placed outdoors to detect weather conditions, dust or garbage may accumulate in the first light-transmitting port 111 and the second light-transmitting port 121, thereby obstructing the transmission of light and affecting the accuracy of the measurement results. The replaceable dust-blocking film 700 can be replaced regularly to avoid dust accumulation. Specifically, the weather detection device can also include a middle support 710, which is supported between the insulation body 100 and the dust-blocking film 700 and is used to support the dust-blocking film 700.

The rotation of the roller 800 can be manual or electric.
[0067] In one embodiment, reference Figure 4 The roller 800 includes a feeding roller 810 and a reeling roller 820. The feeding roller 810 and the reeling roller 820 are respectively arranged on both sides of the heat insulating body 100, and the two ends of the dust blocking film 700 are respectively wound on the feeding roller 810 and the reeling roller 820, so that the dust blocking film 700 covers the heat insulating body 100. In addition, the reeling roller 820 is connected to a reeling motor 830, which can realize automatic replacement of the dust blocking film 700.
[0068] In one embodiment, the dust-blocking film 700 is a polyethylene film, which is low in cost and can transmit far infrared light. In addition, the dust-blocking film 700 can also be any film layer with high far infrared light transmittance.
