Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building thermal detection equipment, in particular to a building external thermal radiation monitoring device. BACKGROUND

[0002] The heat gain and heat loss performance of building envelope (for example, wall, roof and door and window, etc.) directly affects the building energy consumption and indoor thermal comfort, and its heat exchange process is closely related to the complex radiation environment.

[0003] The building external thermal radiation includes short wave radiation (such as direct solar radiation and sky scattered radiation) and long wave radiation (such as sky long wave radiation, ground reflected long wave radiation and long wave radiation of surrounding buildings), and the short wave radiation and long wave radiation jointly determine the net radiation heat gain and heat loss of the envelope. Therefore, accurately monitoring the full waveband thermal radiation of different parts of the building is the core data support for building energy saving design and thermal performance optimization.

[0004] However, the existing building thermal radiation monitoring technology has the problems of single measurement dimension and incomplete radiation waveband coverage. The traditional solar radiation sensor (such as total radiation meter) is usually designed with a single probe, which can only measure the total radiation on the horizontal plane and cannot cover the radiation receiving direction of different parts of the building, such as vertical facade, inclined roof and corner. The radiation environment of different parts of the building is very different (such as strong direct solar radiation on the south facade and mainly sky scattering and long wave radiation on the north facade), and the single horizontal plane measurement data cannot reflect the overall radiation distribution of the building, resulting in large error in the thermal calculation of the envelope. The existing equipment mainly measures the "total radiation" and cannot distinguish the contribution ratio of short wave radiation and long wave radiation. Since the thermal effect mechanism of short wave radiation (mainly from the sun) and long wave radiation (mainly from the environment) is different, and the absorption rate and reflectivity of the envelope to the two types of radiation are different, only measuring the total radiation cannot accurately calculate the heat gain / loss of the structure, which affects the scientificity of energy saving design. The existing thermal radiation monitoring technology cannot meet the actual application requirements. SUMMARY

[0005] The main purpose of the present application is to provide a building external thermal radiation monitoring device, which aims to solve the problem that the existing thermal radiation monitoring technology cannot meet the actual application requirements.

[0024] This invention proposes a device for monitoring external thermal radiation of buildings.

[0025] like Figures 1 to 3 The illustrated building exterior thermal radiation monitoring device includes a main controller, a communicator, and at least one detection mechanism. The detection mechanism includes a main frame 1, a shortwave radiation sensor, a longwave radiation sensor, and a sub-controller. Both the shortwave and longwave radiation sensors are located on the top side of the main frame 1. The shortwave and longwave radiation sensors are electrically connected to the sub-controller, which acquires the detection data from the shortwave and longwave radiation sensors, respectively. The communicator is signal-connected to both the main controller and each sub-controller. The main controller determines each detection point based on the target building, ensuring that at least one detection mechanism is installed at each detection point. The main controller acquires the detection data from the detection mechanisms at each detection point via the communicator.

[0026] Multiple detection points are set up according to the target building, and at least one detection agency is set up in each detection point. Through multi-point collection, the accuracy of detection data is ensured. The detection agencies collect detection data through short-wave radiation sensors and long-wave radiation sensors respectively, which further improves the accuracy of the data and better meets the practical application needs of existing thermal radiation monitoring technology.

[0027] Specifically, the shortwave radiation sensor is a silicon photodiode type sensor (model S1226-8BQ), with a detection wavelength range of 0.3μm to 3μm (covering both direct and diffuse solar radiation bands), a response time of less than or equal to 10μs, and a measurement range of 0 to 2000W / m. 2 The measurement accuracy is ±2% FS, and the linearity is less than or equal to ±1% FS. The front end of the shortwave radiation sensor is equipped with a quartz glass light-transmitting window (2mm thick) with a light transmittance greater than or equal to 95% (0.3μm to 3μm band).

[0028] The long-wave radiation sensor used is a thermocouple-type radiation sensor (model TPF-1), with a detection wavelength range of 3μm to 50μm (covering the long-wave radiation band of the sky, ground, and surrounding buildings), a response time of less than or equal to 500ms, and a measurement range of 0 to 1000W / m. 2 The measurement accuracy is ±3% FS, and the linearity is less than or equal to ±1.5% FS. The front end of the long-wave radiation sensor is equipped with a calcium fluoride light-transmitting window (3mm thick), with a light transmittance greater than or equal to 90% (3μm to 50μm wavelength band).

[0029] Specifically, the main controller acquires a frontal image of the target building and determines its boundary contour based on the image. It acquires a baseline, set intervals, and preset orientations, and determines several target points based on these intervals and orientations. Based on the baseline and each target point, it determines the distance data from each target point to the baseline. Based on these distance data, it determines the increment intervals for each distance, and the maximum value in each increment interval is selected as the candidate point. Based on the positions of the candidate points in the boundary contour and the frontal image, it marks the positions of the candidate points in the frontal image. The main controller acquires confirmation information and, based on this information and the candidate points in the frontal image, determines each detection point. The boundary contour includes lines in four directions: top, bottom, left, and right. The preset orientation is generally the top position; when the preset orientation is the top position, the baseline is the horizontal line at the bottom position. The distribution trend of the top of the target building is determined by the distances from each target point to the baseline. Then, the maximum value in each increment interval is selected, and detection points are chosen from the highest local points on the top of the target building to ensure maximum accuracy in data acquisition.

[0030] Specifically, the baseline is the horizontal line in the boundary contour that is close to the actual ground position; the interval is set to the number of pixels, for example, a target point is taken every three pixels along the extension direction of the line from left to right at the upper position; the distance data is the pixel distance from the target point to the baseline.

[0031] The main frame 1 includes a fixed base 2, a telescopic rod 11, and a mounting platform 3. The telescopic rod 11 is located between the fixed base 2 and the mounting platform 3. One end of the telescopic rod 11 is detachably connected to the fixed base 2, and the other end is detachably connected to the mounting platform 3. A transparent cover 12 is installed on the side of the mounting platform 3 away from the fixed base 2. Both the short-wave radiation sensor and the long-wave radiation sensor are installed inside the transparent cover 12. The inner wall of the transparent cover 12 is coated with a fluorocarbon waterproof coating, and the outer wall is coated with a nano self-cleaning coating. The transparent cover 12 adopts a double-layer structure of an inner fluorocarbon waterproof coating and an outer nano self-cleaning coating, which effectively reduces and avoids the adsorption of external organic matter, ensures the accuracy of the collected data, and provides a certain degree of waterproofing to ensure the safety of the short-wave radiation sensor and the long-wave radiation sensor. The telescopic rod 11 adjusts the distance between the fixed base 2 and the mounting platform 3 to ensure that the short-wave radiation sensor and the long-wave radiation sensor inside the transparent cover 12 are at a suitable height for data acquisition.

[0032] Specifically, the inner fluorocarbon waterproof coating is a polyvinylidene fluoride (PVDF) material layer with a thickness of 30μm to 50μm, a water contact angle greater than or equal to 110°, and a water absorption rate less than or equal to 0.5%. It has excellent waterproof and oil-proof properties and can prevent rainwater penetration and oil adhesion. The outer nano self-cleaning coating is an anatase nano TiO2 material layer with a thickness of 20μm to 30μm. SiO2 modifier is added to improve adhesion. Under visible light irradiation, it can produce photocatalysis to decompose the attached dust and organic matter. At the same time, it has superhydrophilicity (water contact angle less than or equal to 10°), which can wash away residual dust when rainwater is washed away. The self-cleaning efficiency is greater than or equal to 85%, eliminating the need for manual wiping and extending the maintenance cycle to six months.

[0033] The mounting platform 3 includes a mounting frame 31 and a support plate 32. The transparent cover 12 is positioned on the support plate 32 away from the fixed base 2. The mounting frame 31 is connected to the side of the support plate 32 away from the transparent cover 12. The side of the mounting frame 31 away from the support plate 32 is detachably connected to the end of the telescopic rod 11 away from the fixed base 2. The mounting frame 31 is equipped with a cleaning mechanism 4. A sub-controller is electrically connected to the cleaning mechanism 4. The controller is used to control the cleaning mechanism 4 to remove airborne dust from the surface of the transparent cover 12 at preset time points. The outer nano self-cleaning coating, combined with the cleaning mechanism 4, further removes airborne dust from the outer surface of the transparent cover 12, increasing the self-cleaning efficiency of the transparent cover 12 to 95% within one year, achieving an ultra-long maintenance cycle.

[0034] The cleaning mechanism 4 includes a track 41, an electrically controlled slide 42, a connecting frame 43, a power supply module 44, and a fan 45. The track 41 is arranged horizontally around the mounting frame 31, and the electrically controlled slide 42 is slidably connected to the track 41. The fan 45 is located on the outside of the transparent cover 12. One end of the connecting frame 43 is connected to the electrically controlled slide 42, and the other end of the connecting frame 43 is connected to the fan 45. The power supply module 44 is located on the connecting frame 43 and is used to power the fan 45. A sub-controller is electrically connected to the fan 45 and is used to control the electrically controlled slide 42 to slide along the track 41 and drive the fan 45 to rotate circumferentially around the transparent cover 12 through the connecting frame 43. The sub-controller is also used to drive the fan 45 to blow away the floating dust on the outer wall of the transparent cover 12 when the fan 45 rotates circumferentially around the transparent cover 12. The electrically controlled slide 42 slides along the track 41, enabling the fan 45 to blow air around the transparent cover 12, thereby blowing off excess dust on the transparent cover 12 and further extending the maintenance cycle.

[0035] Specifically, the energy supply module 44 is a photovoltaic energy storage structure. Photovoltaic power generation and energy storage structures are quite common and will not be described in detail here.

[0036] The cleaning mechanism 4 also includes an electrically controlled lifting column 46, an electrically controlled telescopic column 47, and a crossbeam 48. The crossbeam 48 is horizontally positioned between the electrically controlled slide 42 and the fixed base 2. The electrically controlled lifting column 46 is positioned on the side of the electrically controlled slide 42 facing the fixed base 2. The output end of the electrically controlled lifting column 46 is connected to the crossbeam 48 via the electrically controlled telescopic column 47. The electrically controlled telescopic column 47 is used to drive the crossbeam 48 to move horizontally. The end of the connecting frame 43 away from the fan 45 is connected to the crossbeam 48. The sub-controller is electrically connected to the electrically controlled telescopic column 47 and the electrically controlled lifting column 46 respectively. The sub-controller is used to control the electrically controlled lifting column 46 and the electrically controlled telescopic column 47 respectively, moving the connecting frame 43 to the side of the support plate 32 facing the fixed base 2. The electrically controlled lifting column 46 and electrically controlled telescopic column 47 are set so that the fan 45 operates around the transparent cover 12. When the fan 45 is not started, the electrically controlled lifting column 46 drives the connecting frame 43 to descend, and the electrically controlled telescopic column 47 drives the connecting frame 43 to move closer to the mounting frame 31 so that the connecting frame 43 carries the fan 45 into the position below the support plate 32.

[0037] Specifically, the main controller is used to acquire weather data, determine the wind force level based on the weather data, and determine whether the wind force level is greater than the preset level. When the wind force level is greater than or equal to the preset level, it controls the electrically controlled lifting column 46 and the electrically controlled telescopic column 47 to move the connecting frame 43 to the position below the support plate 32. When the wind force level is less than the preset level, it first controls the electrically controlled lifting column 46 and the electrically controlled telescopic column 47 to move the fan 45 to the outside of the transparent cover 12 through the connecting frame 43. Then, it controls the electrically controlled sliding seat 42 and the fan 45 to make the fan 45 circle the transparent cover 12 a preset number of times and blow air to remove dust.

[0038] A fixing seat 33 is provided on the side of the support plate 32 away from the transparent cover 12. The fixing seat 33 is located on one side of the mounting frame 31. A slot 34 is provided on the side of the fixing seat 33 away from the mounting frame 31. An installation groove 35 is opened in the slot 34 near the support plate 32, and an electromagnet 36 is installed in the installation groove 35. An insert plate 49 is provided on the side of the connecting frame 43 away from the cross frame 48. A limiting through hole is opened in the insert plate 49 vertically. A sub-controller is electrically connected to the electromagnet 36. The sub-controller is used to control the output end of the electromagnet 36 to insert the insert plate 49 into the slot 34 and then insert the insert plate 49 into the limiting through hole when the connecting frame 43 moves to the side of the support plate 32 facing the fixed base 2. When the connecting frame 43 moves to the position below the support plate 32, the insert plate is inserted into the slot 34, so that the output end of the electromagnet 36 is inserted into the limiting through hole, fixing the relative position of the connecting frame 43 and the mounting platform 3, and preventing the connecting frame 43 from being blown off by excessive wind.

[0039] Two fixing plates 21 are provided on the outer side of the fixed base 2, spaced apart and horizontally arranged. The fixed base 2 is located between the two fixing plates 21. One fixing plate 21 is hinged to the fixed base 2 at one end via a hinge shaft, and the other fixing plate 21 is hinged to the fixed base 2 at the other end via a hinge shaft. Both hinge shafts are horizontally arranged and parallel to each other, with the fixed base 2 located between them. Each fixing plate 21 has at least two first fixing through holes 22 along its thickness. The fixing plates 21 are adjusted according to the slope of the ground, and the fixed base 2 is then fixed to the ground using expansion bolts and the multiple first fixing through holes 22.

[0040] Two connecting pipes 23 are also provided on the side of the fixed base 2 facing the mounting platform 3. The two connecting pipes 23 are arranged in parallel and spaced apart, and the telescopic rod 11 is located between the two connecting pipes 23. The axial direction of the two connecting pipes 23 is perpendicular to the extension direction along one fixed plate 21 to the other fixed plate 21. Two limiting plates 24 are also provided on the outside of the fixed base 2. Two insertion tubes 25 are provided on the side of the two limiting plates 24 facing the fixed base 2. The two insertion tubes 25 of one limiting plate 24 are inserted into the two connecting pipes 23 from one end, and the two insertion tubes 25 of the other limiting plate 24 are inserted into the two connecting pipes 23 from the other end. Two fixing structures 5 are provided on the outside of the fixed base 2. The two fixing structures 5 are used to fix the relative position of the two limiting plates 24 and the fixed base 2. At least two second fixing through holes 26 are opened along the thickness of the two limiting plates 24.

[0041] The fixing structure 5 includes a screw 51 and two fixing nuts 52. The screw 51 passes through two coaxial insertion tubes 25 in sequence. One fixing nut 52 is threaded to one end of the screw 51, and the other fixing nut 52 is threaded to the other end of the screw 51, clamping and fixing the two limiting plates 24 to the outside of the fixing base 2. Facing a narrower area, the two limiting plates 24 clamp the ground, and the upper ends of the two limiting plates 24 are fixed by the two fixing structures 5 and the fixing base 2. The two limiting plates 24 are then fixed relative to the ground by the cooperation of expansion bolts and multiple second fixing through holes 26.
