Description

Technical Field

[0001] The utility model relates to the technical field of radar equipment, in particular to a radar protective cover used in the field. Background Art

[0002] Radar shields are widely used in field environments to protect radars from adverse weather conditions. These shields are typically constructed of durable materials and designed to withstand wind, rain, snow, and other natural elements, ensuring the proper functioning of the radar and extending its service life. This is especially true in high-latitude regions, where cold winters are often accompanied by heavy snowfall, placing even higher demands on radar shields.

[0003] While existing radar shields can provide a certain degree of protection, they often fail to specifically address the issue of snow cover. Snow covering the surface of a radar shield can attenuate radar signals, thereby impacting the radar's detection performance. When snow accumulates to a certain level, the shield's weight increases, potentially putting pressure on the shield's structure and even damaging it. Furthermore, the melting and refreezing of snow can form ice on the shield's surface, further reducing radar signal penetration and impacting radar performance.

[0004] Therefore, existing radar shields, when used in high-latitude winter snowfall, face issues with radar signal attenuation caused by snow cover and structural safety issues. This limits the reliability and effectiveness of radars in adverse weather conditions. Therefore, developing a shield technology that can effectively remove snow and maintain stable radar signal transmission is an urgent problem in the current radar application field. Utility Model Content

[0005] The purpose of the present invention is to address the above-mentioned problems and provide a radar shield for outdoor use. By providing a linear structure of the heating device and gradually reducing its arrangement density from top to bottom, the present invention achieves effective snow removal. This design particularly optimizes the protection effect in high-latitude areas under heavy snowfall in winter. It not only reduces the radar signal attenuation caused by snow accumulation, ensuring the normal detection performance of the radar equipment, but also reduces the structural safety risk of the shield due to the heavy pressure of snow. At the same time, the integrated linkage of the heating device with the control device and the snow thickness sensor further improves energy utilization efficiency, avoids unnecessary energy waste, and ensures the stable operation and long-term reliability of the radar shield under adverse weather conditions.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A radar protective cover for outdoor use comprises a cover body capable of accommodating radar equipment, a control device, and a snow thickness sensor for detecting the thickness of snow on the surface of the cover body. The cover body is provided with a heating device capable of acting on the outer surface of the cover body. The heating device is a linear structure arranged on the cover body, and the density of the linear structure gradually decreases from the top to the bottom of the cover body. The heating device and the snow thickness sensor are both connected to the control device by signal.

[0008] Due to the adoption of the above technical solutions, this design can provide a stronger heating effect in the area with thicker snow at the top of the cover, while reducing the heating power in the area with less snow at the bottom, thereby optimizing heating efficiency and reducing energy consumption. At the same time, the linear arrangement of the heating device can evenly distribute the heat on the surface of the cover, avoiding local overheating or insufficient heating.

[0009] Furthermore, the cover body includes a side wall cover and a top cover, the side wall cover is formed by a plurality of side wall sub-units, the side wall cover is an annular structure, and the top cover is buckled with an opening at the top of the side wall cover.

[0010] The above technical solution can make the cover have good structural strength and stability, and is easy to assemble and maintain. The modular design of the side wall subunits makes the cover more flexible during transportation and installation, and can adapt to the installation requirements of different field environments.

[0011] Furthermore, the cover body also includes a base, which is an annular structure and is arranged at the opening at the bottom of the side wall cover. The side wall cover is a spherical band structure, and the top cover is a first spherical cap structure that matches the spherical band structure. The side wall cover and the top cover together form a hollow shell, and the hollow shell is a second spherical cap structure obtained by cutting the spherical shell by the plane where the base is located.

[0012] Thanks to the aforementioned technical solution, the spherical design ensures excellent aerodynamic performance and reduces wind resistance, while also providing a larger internal space for easier installation and maintenance of radar equipment. The spherical band structure of the sidewalls effectively disperses external wind forces, reducing vibration and fatigue damage to the enclosure. The top cover's first spherical cap forms a strong seal with the sidewalls, preventing snow and rain from entering the enclosure, thereby protecting the radar equipment from environmental damage.

[0013] Furthermore, the heating device at the top cover is arranged in a spiral shape; and the heating device on the side wall cover is arranged in a serpentine shape.

[0014] The above technical solution enables the heating devices to be evenly distributed across the cover surface, improving heating efficiency while reducing interference between heating devices and extending service life. The spirally arranged heating devices form a continuous heating belt in the top cover area, effectively covering the entire surface and preventing snow accumulation there. The serpentine-shaped heating devices, on the other hand, are evenly distributed along the curved surface of the sidewalls in the spherical belt area, ensuring even heat transfer to all parts of the cover, thereby improving the overall heating effect.

[0015] Furthermore, the side wall cover includes several layers of sub-ball bands separated by horizontal planes, and each sub-ball band is formed by several side wall sub-units arranged side by side; and an independent heating device is arranged on each side wall sub-unit.

[0016] Thanks to the aforementioned technical solution, the independent heating device design allows the heating power of each sidewall sub-unit to be adjusted according to the actual snow depth and ambient temperature, thus achieving precise heating and avoiding energy waste. In addition, the layered design of the sub-spherical belts enables the heating device to form multiple heating zones on the cover surface, further improving heating uniformity and efficiency.

[0017] Furthermore, an air inlet is provided on the base, and an air outlet is provided on the side wall cover. The air inlet and the air outlet are arranged on both sides of the cover body relative to each other to form a heat dissipation component.

[0018] Thanks to this technical solution, even in hot environments, heat from within the enclosure is quickly dissipated through the air inlet and outlet, maintaining a stable internal temperature and extending the life of the equipment. The relative positioning of the inlet and outlet creates an effective airflow path, accelerating heat dissipation from within the enclosure, thereby preventing performance degradation or damage to the radar equipment due to excessive internal temperatures. Furthermore, the heat dissipation component design helps dissipate moisture from within the enclosure, preventing corrosion or equipment failure caused by moisture accumulation.

[0019] Furthermore, the air outlet is a horizontal hole, the heating device is arranged in a serpentine shape from top to bottom, and the horizontal hole and the heating device are staggered with each other.

[0020] Due to the adoption of the above technical solution, interference between the heating device and the air outlet is effectively avoided.

[0021] Furthermore, the air outlet is located in the upper area of ​​the side wall cover.

[0022] Due to the adoption of the above technical solution, a height difference is formed between the air inlet and the air outlet, so that the air path can pass through the radar equipment in the cover, achieving a better heat dissipation effect.

[0023] Furthermore, multiple heat dissipation components are evenly distributed on the cover along the circumference, and a switch cover matching the air outlet is provided at the air outlet. The switch cover is connected to the control device signal, and also includes a wind direction sensor that can detect the wind direction at the cover. The wind direction sensor is connected to the control device signal, and the control device can control the switch cover at the air outlet to open or close according to the wind direction data collected by the wind direction sensor.

[0024] Due to the adoption of the above technical solution, the heat inside the cover can be quickly discharged through the heat dissipation component. At the same time, the opening and closing state of the switch cover is automatically adjusted according to the wind direction data to ensure that the open air outlet matches the wind direction, reduce the turbulence inside the cover, and effectively utilize wind energy to further improve the heat dissipation efficiency.

[0025] Furthermore, it also includes a temperature sensor for detecting the temperature inside the cover, and an independent fan is provided at each air inlet. The temperature sensor and the fan are both connected to the control device by signal. The control device can control the start or stop of the fan based on the temperature data collected by the temperature sensor.

[0026] Due to the adoption of the above technical solution, when the heat dissipation effect of the cover using natural wind is insufficient, the fan can be turned on to improve the heat dissipation efficiency, thereby achieving precise temperature control and effectively reducing energy consumption.

[0027] In summary, due to the adoption of the above-mentioned technical solution, the beneficial effects of the present application are as follows: by arranging a heating device on the cover body and designing the heating device as a linear structure with a density gradually decreasing from the top to the bottom, it is possible to provide a stronger heating effect in the area with thicker snow on the top of the cover body, and reduce the heating power in the area with less snow at the bottom, thereby optimizing the heating efficiency and reducing energy consumption. At the same time, the linear arrangement of the heating device can evenly distribute the heat on the surface of the cover body, avoiding local overheating or insufficient heating, thereby effectively preventing structural damage or performance degradation caused by uneven heat distribution during the melting of snow. In addition, the cover body adopts a spherical band structure and a spherical crown structure design, which not only has good aerodynamic performance and can reduce wind resistance, but also can provide a larger internal space, which is convenient for the installation and maintenance of radar equipment. The heating device at the top cover is arranged in a spiral line, and the heating device on the spherical band is arranged in a snake shape, which further improves the heating efficiency and uniformity. The setting of the heat dissipation component and the coordination of the wind direction sensor and the control device enable the heat inside the cover to be quickly discharged according to the external wind direction conditions. The fan can also be adaptively adjusted in combination with the temperature inside the cover to keep the temperature inside the cover stable and extend the service life of the equipment.

[0033] The present invention will be described in detail below with reference to the accompanying drawings.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Example 1

[0036] A radar shield for use in the field, such as Figure 1-Figure 2 As shown, the device comprises a housing 1 capable of accommodating radar equipment, a control device, and a snow thickness sensor for detecting the thickness of snow on the surface of the housing 1. The housing 1 is provided with a heating device 2 capable of acting on the outer surface of the housing 1. The heating device 2 is a linear structure arranged on the housing 1, with the density of the linear structure gradually decreasing from the top to the bottom of the housing 1. The heating device 2 and the snow thickness sensor are both signal-connected to the control device. Preferably, the heating device 2 can be a carbon fiber heating wire, a PTC heating cable, etc., and is arranged on the inner wall of the housing 1. The snow thickness sensor can be a capacitive array embedded in the surface of the housing 1 to monitor the local dielectric constant of snow in real time. Alternatively, the radar equipment protected therein can be integrated with a millimeter wave transmission module. Through time-sharing multiplexing, the snow thickness on the surface of the housing 1 can be periodically detected in the event of extreme weather. The choice of snow thickness sensor can be set according to the situation and is not specifically limited here.

[0037] Specifically, this design can provide a stronger heating effect in the area with thicker snow at the top of the cover 1, while reducing the heating power in the area with less snow at the bottom, thereby optimizing heating efficiency and reducing energy consumption. At the same time, the linear arrangement of the heating device 2 can evenly distribute heat on the surface of the cover 1, avoiding local overheating or insufficient heating. The radar protective cover used in the field detects the thickness of snow on the surface of the cover 1 in real time through a snow thickness sensor, and transmits the data to the control device; the control device adjusts the power of the heating device 2 according to the snow thickness data, wherein the linear structure arrangement density of the heating device 2 gradually decreases from the top to the bottom of the cover 1, so that the cover 1 can obtain stronger heating in the area with thicker snow at the top under the same current drive, while the heating power in the bottom area is reduced, simplifying the drive design of the heating device 2. Of course, zoned and differentiated power heating can also be achieved according to specific needs.

[0038] The cover body 1 includes a side wall cover 101 and a top cover 102 . The side wall cover 101 is formed by a plurality of side wall sub-units 1011 . The side wall cover 101 is an annular structure. The top cover 102 is buckled into the opening at the top of the side wall cover 101 .

[0039] Specifically, the enclosure 1 possesses excellent structural strength and stability, while also facilitating assembly and maintenance. The modular design of the sidewall subunits 1011 allows for greater flexibility during transportation and installation, adapting to the installation requirements of diverse field environments. In this embodiment, carbon fiber heating wires are used in the high-power consumption areas of the top cover 102 to rapidly melt snow, while PTC heating cables are used in the low-power consumption areas of the sidewalls 101 for precise temperature control.

[0040] The cover body 1 also includes a base 103, which is an annular structure. The base 103 is arranged at the opening at the bottom of the side wall cover 101. The side wall cover 101 is a spherical band structure. The top cover 102 is a first spherical cap structure that matches the spherical band structure. The side wall cover 101 and the top cover 102 together form a hollow shell, which is a second spherical cap structure obtained by cutting the spherical shell by the plane where the base 103 is located.

[0041] Specifically, the spherical design enables enclosure 1 to possess excellent aerodynamic performance, reducing wind resistance while providing a larger internal space for easier installation and maintenance of radar equipment. The spherical band structure of the sidewall cover 101 effectively disperses external wind forces, reducing vibration and fatigue damage to the enclosure 1. The first spherical cap structure of the top cover 102 forms a strong seal with the sidewall cover 101, preventing external snow and rain from entering the enclosure 1, thereby protecting the radar equipment from environmental corrosion.

[0042] The heating device 2 on the top cover 102 is arranged in a spiral shape; the heating device 2 on the side wall cover is arranged in a serpentine shape.

[0043] Specifically, the heating devices 2 can be evenly distributed across the surface of the housing 1, improving heating efficiency while reducing interference between the heating devices 2 and extending their service life. Helically arranged heating devices 2 form a continuous heating belt in the top cover 102 area, effectively covering the entire surface of the top cover 102 and preventing snow accumulation in the top cover 102 area. Meanwhile, serpentine-shaped heating devices 2 are evenly distributed along the curved surface of the sidewall 101 in the spherical belt area, ensuring even heat transfer to all parts of the housing 1, thereby improving the overall heating effect.

[0044] The sidewall cover 101 comprises four layers of sub-ball zones evenly separated in height by a horizontal plane: from top to bottom, they are the first sub-ball zone, the second sub-ball zone, the third sub-ball zone, and the fourth sub-ball zone. Each sub-ball zone is formed by fourteen sidewall sub-units 1011 arranged side by side. The sidewall sub-units 1011 of each layer of sub-ball zones have the same shape. Each sidewall sub-unit 1011 is equipped with an independent heating device 2.

[0045] Specifically, the independent design of the heating device 2 allows the heating power of each sidewall subunit 1011 to be adjusted according to the actual snow thickness and ambient temperature, thereby achieving precise heating and avoiding energy waste. In addition, the layered design of the sub-ball bands enables the heating device 2 to form multiple heating areas on the surface of the cover 1, further improving the uniformity and efficiency of heating.

[0046] Example 2

[0047] Example 2 is a further improvement of Example 1; further explanation, the same parts are not repeated here, such as Figure 3-Figure 4 As shown, the base 103 is provided with an air inlet 3, and the side wall cover 101 is provided with an air outlet 4. The air inlet 3 and the air outlet 4 are relatively arranged on both sides of the cover body 1 to form a heat dissipation component.

[0048] Specifically, in hot environments, heat from within the housing 1 is rapidly discharged through the air inlet 3 and air outlet 4, maintaining a stable internal temperature and extending the life of the equipment. The relative positioning of the air inlet 3 and air outlet 4 creates an effective air flow channel, accelerating the discharge of heat from within the housing 1, thereby preventing performance degradation or damage to the radar equipment due to excessive internal temperatures. Furthermore, the design of the heat dissipation component also helps to remove moisture from within the housing 1, preventing equipment corrosion or malfunction caused by moisture accumulation. This design makes the radar shield for field use more adaptable to changing outdoor environments.

[0049] The air outlet 4 is a horizontal hole, and the heating device 2 is arranged in a serpentine shape from top to bottom, and the horizontal hole and the heating device 2 are staggered with each other.

[0050] Specifically, the mutual interference between the heating device 2 and the air outlet 4 is effectively avoided.

[0051] The air outlet 4 is located in the upper area of ​​the side wall cover 101 .

[0052] Specifically, a height difference is created between the air inlet 3 and the air outlet 4, allowing the air to pass through the radar equipment within the enclosure 1, achieving better heat dissipation. If the air outlet 4 is too high, hot air will naturally rise, forming a stagnant area below the air outlet 4, making it difficult to effectively discharge from the enclosure 1. If the air outlet 4 is too low, the natural convection driving force will be weak, and the cooling air will not be able to effectively reach the radar equipment, resulting in insufficient heat dissipation in the core area. In this embodiment, the air outlet 4 is located in the second sub-spherical zone, which can better adapt to the radar equipment.

[0053] The air inlet 3 and the air outlet 4 are both provided with filter components to prevent dust from entering the cover body 1.

[0054] The fourteen heat dissipation components are evenly distributed on the cover body 1 along the circumference. A switch cover matching the air outlet 4 is provided at the air outlet 4. The switch cover is connected to the control device signal. It also includes a wind direction sensor that can detect the wind direction at the cover body 1. The wind direction sensor is connected to the control device signal. The control device can control the opening or closing of the switch cover at the air outlet 4 based on the wind direction data collected by the wind direction sensor. Preferably, the wind direction sensor can adopt an electrostatic capacitive sensor array. The electrostatic capacitive sensor can be arranged according to the arrangement of the side wall subunits 1011 to achieve 360-degree wind direction monitoring. A mechanical wind direction sensor can also be set at each air inlet 3 to achieve 360-degree wind direction monitoring. The wind direction sensor can be selected according to needs and is not limited here.

[0055] Specifically, the heat inside the cover 1 can be quickly discharged through the heat dissipation component, and the opening and closing state of the switch cover can be automatically adjusted according to the wind direction data to ensure that the opened air outlet 4 matches the wind direction, reduce the turbulence inside the cover 1, and effectively utilize wind energy to further improve the heat dissipation efficiency.

[0056] It also includes a temperature sensor for detecting the temperature inside the cover body 1. Each air inlet 3 is provided with an independent fan. The temperature sensor and the fan are both connected to the control device by signal. The control device can control the start or stop of the fan based on the temperature data collected by the temperature sensor.

[0057] Specifically, when the heat dissipation effect of the cover body 1 using natural wind is insufficient, the fan can be turned on to improve the heat dissipation efficiency, thereby achieving precise temperature control and effectively reducing energy consumption.

[0058] During the heat dissipation process, the temperature sensor detects the internal temperature of the cover 1, and the wind direction sensor detects the external wind direction. The control device controls the opening or closing of the switch cover of the heat dissipation component and the start or shutdown of the fan based on the temperature data and wind direction data, forming a natural wind or forced wind heat dissipation path to ensure efficient heat discharge.
