Description
Technical Field
The invention belongs to the field of meteorological monitoring equipment, and relates to a spiral type ventilation radiation-proof cover.
Background
The temperature and humidity sensor for observing the atmospheric temperature and humidity can be subjected to solar radiation and ground reflected radiation, so that the measured value of the temperature and humidity sensor is higher than the real atmospheric temperature and humidity value. Among factors causing temperature and humidity measurement errors, the temperature and humidity sensor device and the matched system are 1-2 orders of magnitude lower than the measurement errors caused by radiation temperature rise, so that radiation becomes a main source influencing the temperature and humidity measurement errors.
In the practical application process, a shutter or a ventilation radiation-proof cover or other equipment is usually used for reducing the influence of external radiation on the measurement accuracy of the temperature and humidity sensor. The common louver box consists of a plurality of layers of blades, the natural ventilation radiation-proof cover consists of a plurality of layers of ring blades, the natural ventilation radiation-proof cover is provided with an umbrella-shaped upper plate and a lower plate with a radiation-proof function, and the temperature and humidity sensor is placed inside the louver box or the natural ventilation radiation-proof cover. However, the multilayer blade and ring structure of the traditional louver box and the natural radiation protection cover have the problems of being not beneficial to air flow circulation and poor radiation protection effect. Consequently, there have been forced draft radiation shields with fans that, while creating higher velocity air flow to enhance ventilation, are bulky and do not support the power requirements of the fans as is the case with most solar power systems in field weather stations. Moreover, the reliability of the high-power fan in the field cannot be guaranteed for a long time due to environmental factors such as dust, ice, snow, insects and the like.
Aiming at the problems of poor air flow circulation and poor radiation protection effect of the traditional natural radiation protection shield and the problems of large volume, large power consumption and difficult maintenance of the forced ventilation radiation protection shield, a better solution needs to be further explored.

Example 1:
referring to fig. 1 to 4, a spiral ventilation radiation shield I1 includes a plurality of spiral annular radiation-proof sheets 101 stacked one above another, and a gap exists between adjacent radiation-proof sheets 101 to form a spiral ventilation duct 102; the lower edge of the radiation shielding sheet 101 is outwardly enlarged to form an inclined surface for ventilation.
In this embodiment, the horizontal inclination angle of the inclined surface of the radiation shielding sheet 101 is 40 ° to 60 °. The radiation-proof sheets 101 are provided with three connecting holes uniformly distributed around the axis, the connecting holes of the radiation-proof sheets 101 are aligned, and the radiation-proof sheets 101 are fixed in a layered manner through connecting rods inserted in the connecting holes.
The radiation-proof sheet 101 is integrally formed by adopting light engineering plastics (such as PC and ASA) through die sinking processing, and is coated with an ultraviolet radiation-proof coating and a hydrophobic coating on the surface. The radiation protection sheet 101 has the advantages of high strength, light weight, good radiation protection performance, small impurity adhesive force and small wind resistance, ensures radiation protection, enhances air circulation, and is beneficial to improving the measurement accuracy and the service life of a temperature and humidity sensor arranged in the radiation protection sheet.
The temperature and humidity sensor is arranged inside the spiral ventilation radiation-proof cover I1 to measure the temperature and humidity value of air. When low wind speed and radiation temperature rise occur, the expansion density of hot air in the spiral ventilation radiation-proof cover I1 is reduced, the hot air can flow upwards along with the spiral ventilation duct 102 in a spiral mode, and external air is driven to continuously enter the spiral ventilation duct 102, so that the air inlet amount is increased, the ventilation performance is improved, the radiation-proof effect is improved, and the adverse effect of radiation on temperature and humidity measurement is reduced. Meanwhile, dust and impurities attached to the surfaces of the spiral ventilation radiation-proof cover I1 and the temperature and humidity sensor can be taken away by spiral airflow formed by the spiral ventilation air duct 102 of the spiral ventilation radiation-proof cover I1, and the pollution resistance of the spiral ventilation radiation-proof cover I1 and the temperature and humidity sensor is improved and the maintenance frequency is reduced by matching with a hydrophobic coating on the surface of the spiral ventilation radiation-proof cover I1.
Example 2:
as shown in fig. 5 to 7, a spiral ventilation radiation-proof cover II2 is different from the spiral ventilation radiation-proof cover I1 provided in embodiment 1 mainly in that a spiral annular a-shaped flow guide sleeve 201 is embedded in a central cavity at the upper edge of the radiation-proof sheet 101, and the a-shaped flow guide sleeve 201 spirals along with the radiation-proof sheet 101 to form a spiral ventilation duct 102. One side of the a-shaped guide sleeve 201 facing the spiral air duct 102 is provided with a guide surface 202 guiding flow upwards in a spiral manner and a downward spiral a-shaped fixing surface 203 vertically intersected with the guide surface 202 guiding flow upwards in a spiral manner, wherein the horizontal inclination angle of the upward spiral guide surface 202 is 45-80 degrees, and the horizontal inclination angle of the downward spiral a-shaped fixing surface 203 is 10-45 degrees. The end where the a-shaped fixing surface 203 is located is attached to the top of the radiation-proof sheet 101, and a through hole corresponding to the connecting hole of the radiation-proof sheet 101 is formed in the a-shaped fixing surface 203 so that a connecting rod can pass through the through hole, and connection and layered fixing between the radiation-proof sheet 101 and the corresponding a-shaped flow guide sleeve 201 are achieved. The A-type flow guide sleeve 201 is made of light engineering plastics, and is coated with an ultraviolet radiation resistant coating and a hydrophobic coating.
The radiation-proof sheet 101 and the A-shaped flow guide sleeve 201 are used in combination, so that the airflow channel in the vertical direction is gradually reduced, the airflow is accelerated after entering under the condition of low wind speed, the pressure is reduced, and the supplement of new airflow is increased. After acceleration, the faster air flow spirally flows upwards along with the direction of the guide surface of the A-shaped guide sleeve 201, so that the air exchange between the central cavity of the A-shaped guide sleeve 201 and the air near the temperature and humidity sensor arranged in the central cavity is accelerated, and the generated and accumulated hot air is taken away.
In addition, the spiral downward A-shaped fixing surface 203 of the A-shaped flow guide sleeve 201 can also block the infringement of heat radiation, dust and water drops on a temperature and humidity sensor arranged in the central cavity, and the capabilities of radiation protection, dust prevention, water prevention and ventilation efficiency are comprehensively improved.
Example 3:
as shown in fig. 8 to 10, a spiral ventilation radiation shield III3 is different from the spiral ventilation radiation shield I1 provided in embodiment 1 mainly in that a spiral annular B-shaped flow guide sleeve 301 is embedded in a central cavity at the upper edge of a radiation-proof sheet 101, and the B-shaped flow guide sleeve 301 spirals along with the radiation-proof sheet 101 to form a spiral ventilation duct 102. One side of the B-shaped guide sleeve 301 facing the spiral air duct 102 is provided with a guide surface 302 for guiding the air flow downwards in a spiral manner, and is further provided with a B-shaped fixing surface 303 connected with the guide surface 302 for guiding the air flow downwards in a spiral manner, wherein the guide surface 302 for guiding the air flow downwards in a spiral manner is streamline (linear type is also available), the horizontal inclination angle range of the guide surface 302 for guiding the air flow downwards is 55-75 degrees, and the specific value of the horizontal inclination angle is different from that of the inclined surface of the radiation-proof sheet 101. The B-shaped fixing surface 303 is provided with a through hole corresponding to the connecting hole of the radiation-proof sheet 101 for a connecting rod to pass through, so that connection and layered fixation between the radiation-proof sheet 101 and the corresponding B-shaped flow guide sleeve 301 are realized. The B-shaped guide sleeve 301 is made of light engineering plastics, and is coated with an ultraviolet radiation resistant coating and a hydrophobic coating. A gap is also arranged between the B-shaped guide sleeve 301 and the corresponding radiation-proof sheet 101.
The horizontal inclination angles between the guide surface 302 of the B-shaped guide sleeve 301 for guiding the air downwards in the spiral mode and the inclined surface of the corresponding radiation protection sheet 101 are different, so that the air flow in the B-shaped guide sleeve 301 and the corresponding radiation protection sheet 101 generates flow speed difference, and the air exchange speed and efficiency are improved; and the gap between the B-shaped guide sleeve 301 and the corresponding radiation-proof sheet 101 can increase the contact area with air, thereby further accelerating the ventilation efficiency.
In addition, the structure of the B-shaped flow guide sleeve 301 can effectively resist the influence of heat radiation, dust, water drops and the like on the internal temperature and humidity sensor, and the measurement accuracy of the temperature and humidity sensor is improved.
For the spiral ventilation radiation-proof cover I1, the radiation-proof sheet 101 forms a single spiral structure; for the spiral type ventilation radiation-proof cover II2 and the spiral type ventilation radiation-proof cover III3, the radiation-proof sheet 101 is used as an outer spiral, and the A-shaped guide sleeve 201/B-shaped guide sleeve 301 is used as a corresponding inner spiral to form a double-spiral structure. In practical application, according to the actual size of the required spiral ventilation radiation-proof cover, a plurality of flow guide sleeves can be embedded in the radiation-proof sheet 101 to form a multi-spiral structure.
Certainly, in the above embodiment, under the condition that the actual power consumption requirement is met, the direct current fan can be additionally arranged at the top of the spiral ventilation radiation-proof cover to further improve the ventilation effect.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
