Description

Technical Field

[0001] This invention relates to the field of meteorological and atmospheric environmental monitoring technology, specifically to a radiation shield. Background Technology

[0002] In the fields of meteorology and atmospheric environment, sensors (or detectors and other monitoring devices) for meteorological and atmospheric environmental elements need to be installed outdoors, in direct contact with the atmosphere, to monitor meteorological and environmental parameters. To prevent sensors from being exposed to rain, snow, or direct sunlight, protective covers are required to improve their long-term stability and measurement accuracy. Among these, miniature ventilated, rainproof, and radiation-proof covers offer advantages such as small size, light weight, simple structure, and ease of maintenance. With the development of automatic weather stations, automatic environmental monitoring stations, and the Internet of Things (IoT) technology, their applications are becoming increasingly widespread.

[0003] Meteorological monitoring is gradually becoming standard equipment in photovoltaic and wind power plants. These applications place high demands on the continuous operation of meteorological and environmental monitoring devices in the field. In many cases, on-site sensor calibration is required, and in critical situations, multiple backup monitoring systems are needed at the same location. However, currently available miniature radiation shields only support the installation of one sensor. For on-site calibration, the reference sensor needs to be installed in a separate radiation shield, and the sampling itself occurs in two different spatial locations, leading to significant uncertainty in calibration accuracy. For dual-backup operation, a separate sensor and radiation shield are required, increasing both operating costs and requiring more production space and maintenance costs.

[0004] In addition, most of the miniature ventilated rainproof and radiation-proof covers on the market are cylindrical, and while they can provide rain protection, their ventilation performance still has room for improvement.

[0005] Patent application CN111983724A discloses a weather louver. This application includes an inner louver on the cover of the weather louver unit, which effectively prevents rainwater from entering the interior of the weather louver from the side and below. The lower surface of the circuit board mounting base has an annular waterproof protrusion that surrounds the circuit board of the weather louver, effectively protecting the circuit board. However, the aforementioned problems still exist. Summary of the Invention

Detailed Implementation

[0061] To facilitate understanding of the technical solution of the present invention by those skilled in the art, the technical solution of the present invention will now be further described in conjunction with the accompanying drawings.

[0062] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0063] See Figures 1 to 4 This embodiment discloses a radiation shield, including a top cover 1, a heat insulation layer 2, a hollow layer 3, and a load-bearing layer 4.

[0064] See Figures 5 to 7 The top cover 1 has a frustum-shaped structure. The side of the top cover 1 has a first rainproof slope 11 that extends forward from the upper end of the top cover 1. The angle between the first rainproof slope 11 and the horizontal plane is in the range of 30° to 75°. In this embodiment, the angle between the first rainproof slope 11 and the horizontal plane can be set to 50°. By setting the angle as above, it is more conducive to sunshade and rainwater diversion.

[0065] The lower edge of the first rainproof slope 11 is provided with multiple first lower guide angles 12. In this embodiment, three first lower guide angles 12 are provided, and the three first lower guide angles 12 are symmetrically distributed along the central axis of the first rainproof slope 11. At the same time, the angle between the first lower guide angles 12 and the horizontal plane is set to 90°. Each first lower guide angle 12 occupies 45° to 46° of the 360° circular surface of the first rainproof slope 11. Through simulation and testing, it can effectively reduce wind resistance and enhance ventilation efficiency.

[0066] The upper edge of the first rainproof slope 11 is provided with multiple upper guide angles 13. In this embodiment, three upper guide angles 13 are provided, and the three upper guide angles 13 are symmetrically distributed along the central axis of the first rainproof slope 11. At the same time, the angle between the upper guide angle 13 and the horizontal plane is set to be between 15° and 70°. In this embodiment, the angle between the upper guide angle 13 and the horizontal plane can be set to 35°. Each upper guide angle 13 occupies 42° to 46° of the 360° circle of the first rainproof slope 11. Through simulation and testing, it can effectively reduce wind resistance and guide rainwater.

[0067] The top cover 1 has multiple first connecting posts 14 at its upper end. The positions of the multiple first connecting posts 14 are symmetrically distributed along the central axis of the first rainproof slope 11. Each first connecting post 14 has an internal thread for assembling and fixing the radiation shield. In this embodiment, three first connecting posts 14 are provided.

[0068] See Figures 8 to 10The insulation layer 2 is installed below the top cover 1. The insulation layer 2 has a frustum-shaped structure identical to the top cover 1. It also has a forward-extending second rainproof slope 21, identical to the top cover 1. The included angle and chamfer of the second rainproof slope 21 are the same as the first rainproof slope 11 of the top cover 1. Second lower guide chamfers 22 are symmetrically distributed along the central axis of the second rainproof slope 21, and each chamfer 22 occupies 45° to 46° of the 360° circular surface of the second rainproof slope 21. This design effectively reduces wind resistance and enhances ventilation efficiency.

[0069] During assembly, the cut angles of the second rainproof slope 21 of the insulation layer 2 and the first rainproof slope 11 of the top cover 1 correspond to each other. During ventilation, the wind force will not be blocked, which can ensure the ventilation efficiency.

[0070] Multiple through-hole connecting columns 23 are provided on the heat insulation layer 2 for assembling and fixing the heat insulation layer 2 of the radiation shield. In this embodiment, three through-hole connecting columns 23 are provided in symmetrically distributed positions and correspond to the first connecting columns 14 of the top cover 1. After assembly, an independent heat insulation area is formed between the top cover 1 and the heat insulation layer 2 to prevent the temperature of the hollow layer 3 of the radiation shield from rising sharply due to sun exposure.

[0071] See Figures 11 to 13 The hollow layer 3 is installed below the insulation layer 2. The hollow layer 3 has multiple identical radiation-shielding discs 31, each with a forward-extending third rainproof slope 311 identical to that of the top cover 1. The included angle and chamfer of the third rainproof slope 311 are the same as those of the top cover 1's rainproof slope. A third lower guide chamfer 312 is symmetrically distributed along the central axis of the third rainproof slope 311, and the angle between the third lower guide chamfer 312 and the horizontal plane is 90°. Each third lower guide chamfer 312 occupies 45°–46° of the 360° circle of the third rainproof slope 311. This design effectively reduces wind resistance and enhances ventilation efficiency.

[0072] Each radiation shielding disc 31 has a hollow center, forming the first hollow region 313. Specifically, the first hollow region 313 is a Reichstag triangle, with its three bases corresponding to the three lower guide angles of the lower edge of the third rainproof slope 311, facilitating ventilation. This position corresponds to the widest part of the upper platform, which is beneficial for rain protection. The three apex angles of the first hollow region 313 correspond to the un-cut corners of the lower edge of the third rainproof slope 311, which is beneficial for rain protection. This position also corresponds to the narrowest part of the upper platform, which is beneficial for ventilation.

[0073] Multiple through-hole second hollow connecting columns 314 are provided on the radiation shielding disc 31 of the hollow layer 3 for assembling and fixing the hollow layer 3 of the radiation shield.

[0074] In this embodiment, the hollow layer 3 of the radiation shield is used by arranging multiple radiation-shielding discs 31 at equal vertical intervals, assembling them together via connecting rods 5, and connecting them to the heat insulation layer 2 and the top cover 1. The three lower guide angles of the multiple radiation-shielding discs 31 are in the same position. The interior of the multiple radiation-shielding discs 31 forms a Reuleaux triangle hollow region, allowing the interior of the hollow layer 3 of the radiation shield to simultaneously accommodate multiple sensors. In actual use, the number of radiation-shielding discs 31 in the hollow layer 3 can be increased or decreased according to the length of the sensors, so that the hollow region can fully adapt to the length of the sensors. This allows the entire radiation shield to maintain a compact size and has a wider range of applications.

[0075] See Figures 14 to 17 , Figure 14 and Figure 15 This implementation adopts an upper and lower guide bevel structure with an internal Leroy triangular cavity, from which... Figure 14 The four positive directions shown are simulated and analyzed at a wind speed of 10 m / s. Figure 16 and Figure 17 The existing radiation shield adopts a structure without guide angles and with a circular hole inside, from which... Figure 16 Simulation analysis was performed in the four positive directions shown, with a wind speed of 10 m / s. The results are shown in Table 1:

[0076] Table 1 Simulation Drag Coefficient Table

[0077] This radiation shield With a guide angle, the Leroy triangle hole 0.670838 0.67926 0.665316 0.681226 Existing radiation shield No guide angle, round hole 0.735604 0.729098 0.737630 0.729094

[0078] As can be seen from the drag coefficient results in the table above, compared with existing radiation shields, the drag coefficient of the radiation shield in this embodiment can be effectively reduced. Specifically, the simulated drag coefficients in the four directions of the radiation shield in this embodiment are reduced by 9.65%, 7.34%, 10.87%, and 7.03%, respectively. The ventilation effect is significantly improved, and the rainproof and ventilation effects are better.

[0079] See Figures 18 to 20 The load layer 4 is installed below the hollow layer 3. The load layer 4 includes a mounting layer 41 and a sensor fixture 42.

[0080] The mounting layer 41 has a triangular structure, with a second hollow region 413 in the center of the mounting layer 41, which is the same as the first hollow region 313 in the hollow layer 3. The sensor clamp 42 is installed at the lower end of the mounting layer 41. The sensor clamp 42 is used to hold the sensor and accommodate the sensor through the first hollow region 313 and the second hollow region 413.

[0081] Multiple third hollow connecting columns 411 are provided at the upper end of the mounting layer 41, and each third hollow connecting column 411 has a through hole. In this embodiment, three third hollow connecting columns 411 are provided, in the same positions as the first connecting column 14 and the first hollow connecting column 23. The connecting rod 5 is sequentially connected to the third hollow connecting column 411, the second hollow connecting column 314, the first hollow connecting column 23, and the first connecting column 14 to fix the hollow layer 3, the heat insulation layer 2, and the top cover 1 to the upper end of the load layer 4.

[0082] The lower end of the mounting layer 41 is provided with three threaded hole supports 412, which are symmetrically distributed in an isosceles triangle and located at the triangular positions of the Reichstag triangle. These supports are used to fix the radiation shield of this embodiment to the mounting bracket.

[0083] The mounting layer 41 is also provided with a connector mounting slot 414, which can be used to install an M8 connector as needed to flexibly expand the function of the radiation shield in this embodiment.

[0084] The side wall of the threaded hole support column 412 is provided with a threaded through hole. The sensor clamp 42 includes multiple identical clamping plates 421, which are arranged side by side. Both ends of the clamping plates 421 are provided with connecting through holes 4213. The clamp bolts 422 are threadedly connected to the threaded through holes 4213 at both ends of the clamping plates 421 and thus fix the sensor clamp 42.

[0085] See Figures 21 to 23 Each clamping plate 421 has an "M"-shaped structure, with connecting portions 4211 at both ends and an "M"-shaped mounting portion 4212 in the middle. The connecting portions 4211 at both ends are provided with connecting through holes 4213. Clamping bolts 422 pass through the connecting through holes 4213 to fix the clamping plate 421 onto the mounting layer 41. The mounting portion 4212 has pairs of protrusions 4214 and grooves 4215 on both its front and rear sides, allowing the two clamping plates 421 to be arranged opposite each other and clamped together to hold the sensor. In this configuration, the protrusion 4214 on one end of one clamping plate 421 aligns with the groove 4215 on the opposite end of the other clamping plate 421, and vice versa. The two clamping plates 421 can be stacked together, preventing slippage between them when clamping the sensor.

[0086] In this embodiment, three identical clamping plates 421 are provided. These three clamping plates 421 are arranged side-by-side, with the first and third clamping plates 421 arranged identically, and the second clamping plate 421 arranged in the opposite direction, thus forming three spaces for clamping sensors. One, two, or three sensors can be clamped simultaneously. In specific implementations, the sensor clamps 42 can be freely combined as needed. For example, two oppositely arranged clamping plates 421 can form two spaces for clamping sensors, allowing one or two sensors to be clamped simultaneously.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.
