Description

TECHNICAL FIELD

[0001] The utility model belongs to laser radar technical field, concretely relates to a kind of explosion-proof glass radar protective cover. BACKGROUND

[0002] With the development of high-risk industries such as petrochemical industry, natural gas exploitation and military defense, the demand for radar equipment in monitoring and control systems in these fields is increasingly urgent, but at the same time, it also faces unprecedented challenges - how to ensure the stable operation and accurate data collection of radar systems in extreme environments such as flammable and explosive, high temperature and high pressure, or chemical corrosion. Therefore, explosion-proof glass radar protective cover emerges as the times require, becoming a bridge connecting safety and efficiency. On the one hand, explosion-proof glass can resist the impact of the huge shock wave and debris produced by explosion to a certain extent, effectively isolate the explosion source, prevent the leakage of internal sparks or high-temperature gas, and protect the surrounding environment and personnel safety. On the other hand, this material also has good light transmission and electromagnetic transmission, allowing radar waves to penetrate without obstacles, ensuring that radar equipment can continuously and accurately capture target information, which is crucial for military reconnaissance, oil and gas field monitoring, chemical park safety warning, etc.

[0003] However, although explosion-proof glass radar protective cover meets the basic safety and functional requirements in theory, in actual application, the existing technology still exposes several significant defects and deficiencies. In terms of explosion-proof performance, the strength and toughness of some explosion-proof glass still need to be improved, especially in the face of high-intensity explosion impact under extreme conditions, its integrity may be damaged, and it cannot fully perform its role as a barrier, thereby increasing the safety hazard. In addition, even if the glass is not completely broken, its surface may produce small cracks or deformation due to impact, which will further affect the transmission efficiency and accuracy of radar waves.

[0004] From the perspective of signal transmission, the optical uniformity and electromagnetic compatibility of explosion-proof glass are the key to achieving efficient radar detection. However, due to the limitations of material formula or production process, some explosion-proof glasses on the market have unsatisfactory optical properties (such as refractive index, light transmission rate) and electromagnetic properties (such as dielectric constant, loss tangent), which leads to attenuation, scattering or refraction of radar signals when penetrating the protective cover, which not only reduces the detection distance and resolution of radar, but also may introduce false targets, affecting decision-making.

[0005] In terms of durability, explosion-proof glass radar protective cover exposed to harsh environments for a long time also faces multiple tests such as chemical corrosion, ultraviolet aging, extreme temperature changes, etc. These factors together may cause etching, cracking, and transparency reduction on the surface of the glass, not only shortening the service life of the protective cover, but also seriously weakening its explosion-proof and signal transmission performance, increasing maintenance cost and replacement frequency. The utility model discloses a kind of explosion-proof glass radar protective cover, can effectively shield the electromagnetic interference of outside, improve the reliability and security of radar protective cover structure.

[0006] The utility model discloses a kind of explosion-proof glass radar protective cover, can effectively shield the electromagnetic interference of outside, improve the reliability and security of radar protective cover structure.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] The utility model provides a kind of explosion-proof glass radar protective cover, including base and glass cover being set on base;The top of glass cover is provided with upper cover;Base and upper cover are connected by connecting plate.

[0009] Preferably, the glass cover comprises, from inside to outside, a glass layer with added metal oxide, an adhesive layer and a tempered glass layer.

[0010] Preferably, the adhesive layer is transparent.

[0011] Preferably, it further includes a sheet metal part, which is arranged on the base and located inside the glass cover.

[0012] Preferably, the sheet metal part is fixed on the base by M3 screws.

[0013] Preferably, the connecting plate is connected to the upper cover and the base by M4 screws respectively.

[0014] Preferably, the top of the glass cover is inlaid inside the upper cover and fixed by sealing glue.

[0015] Preferably, the bottom of the glass cover is inlaid inside the base and fixed by sealing glue.

[0016] Preferably, the upper cover is made of metal material.

[0017] Preferably, the base is made of metal material.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The base bears the weight of the protective cover and the internal radar equipment, ensuring that the entire structure remains stable in various installation environments. The glass cover protects the radar from external environmental factors such as explosive gases, dust, and moisture. The upper cover is fixedly connected to the top of the glass cover, forming a complete closed structure that further enhances the protective performance of the explosion-proof glass radar protective cover. The connecting plate is used to firmly connect the base and the upper cover together, further improving the reliability and security of the entire protective cover structure.

[0020] Further, the glass cover adopts the multilayer composite explosion-proof glass, and from inside to outside, the glass cover includes the glass layer added with metal oxide, the adhesive layer and the tempered glass layer in sequence. The strong tempered glass surface forms a strong compressive stress layer, can bear larger external force impact and is not easy to break.

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] This utility model provides an explosion-proof glass radar shield, such as Figure 1As shown, the radar dome includes a base 1 and a glass cover 2 mounted on the base 1; a top cover 3 is provided on the top of the glass cover 2; the base 1 and the top cover 3 are connected by a connecting plate 4. The base 1 provides a solid supporting foundation for the explosion-proof glass radar dome, bearing the weight of the dome and the internal radar equipment, ensuring the stability of the entire structure in various installation environments. Whether installed on the ground, wall, or other supporting structures, the base 1 can evenly distribute the weight, preventing structural collapse due to excessive local stress, improving the ease of installation and stability of the radar dome, and ensuring the normal operation of the radar in harsh environments. The glass cover 2 protects the radar from external environmental influences such as explosive gases, dust, and moisture. The top cover 3 is fixedly connected to the top of the glass cover 2, forming a complete closed structure, further enhancing the protective performance of the explosion-proof glass radar dome. The connecting plate 4 is used to firmly connect the base 1 and the top cover 3 together, ensuring the reliability and safety of the entire dome structure.

[0033] Specifically, the glass cover 2 is made of multi-layer composite explosion-proof glass, comprising, from the inside out, a glass layer with added metal oxides, an adhesive layer, and a tempered glass layer. The outer layer is high-strength tempered glass, which undergoes a special heat treatment process to form a strong compressive stress layer on its surface, capable of withstanding significant external impacts without easily breaking. The middle layer is a transparent adhesive layer, using an optically transparent adhesive with good adhesion and flexibility. This adhesive not only firmly bonds the inner and outer glass layers together but also acts as a buffer when the glass is impacted, absorbing some energy and preventing the glass from shattering and scattering. The inner layer is a glass layer with added metal oxides, and other components can be added to give it special electromagnetic properties. Through precise proportioning, it achieves good transmittance of radar signals while effectively shielding against external electromagnetic interference. Furthermore, the glass cover 2 has high transparency, allowing operators to directly observe and inspect the radar equipment without disassembling it. For opaque or low-transparency covers, frequent disassembly and inspection are required. This invention reduces operational complexity and maintenance costs. Meanwhile, the multi-layer composite explosion-proof glass structure of the glass cover 2 can reduce light reflection and reduce the interference of reflected light on radar signals, thereby improving the clarity of optical observation.

[0034] This utility model also includes a sheet metal part 5, which is disposed on the base 1 and located inside the glass cover 2. The sheet metal part 5 is used to fix the radar inside the cover. Through the fixing of the sheet metal part 5, the radar is effectively protected, avoiding damage caused by external impact or collision, and extending the service life of the radar. The sheet metal part 5 is fixed to the base 1 by M3 screws 6. The M3 screws 6 further ensure that the radar will not loosen, shift, or fall off during use; at the same time, the M3 screws 6, as standardized fasteners, are easy to install and disassemble, making the installation and disassembly process of the sheet metal part 5 simpler and more convenient, reducing the difficulty and cost of installation and disassembly.

[0035] The connecting plate 4 is connected to the upper cover 3 and the base 1 respectively via M4 screws 7. As a standard fastener, the M4 screws 7 possess sufficient strength and reliability to ensure a tight connection between the connecting plate 4 and the upper cover 3 and base 1. This not only withstands the weight of the lidar inside the housing but also effectively resists impacts and vibrations from the external environment. The connection via the M4 screws 7 makes the entire housing structure more stable and less prone to loosening or deformation due to external impacts or vibrations. Furthermore, the M4 screws 7 are easy to disassemble and install. This design makes disassembly and maintenance of the housing simpler and more convenient. Whether in harsh weather conditions (such as strong winds, heavy rain, hail, etc.) or in long-term vibration environments (such as when installed on mobile platforms such as vehicles and ships), the explosion-proof glass lidar maintains good stability and will not be affected by external factors in the radar's working accuracy.

[0036] like Figure 2 and Figure 3As shown, the top of the glass cover 2 is embedded inside the upper cover 3 and fixed with sealant. The bottom of the glass cover 2 is embedded inside the base 1 and fixed with sealant. The upper cover 3 is made of metal. The base 1 is made of metal. The glass cover 2 itself has high strength and hardness, and the structural design combined with metal makes the cover sturdy and durable, able to resist mechanical damage such as external impacts and scratches. The upper cover 3 and base 1, made of metal, provide a solid frame for the cover, enhancing its overall pressure and impact resistance, ensuring the cover is sturdy and reliable even in complex and changing environments, and is not easily deformed or damaged. The sealant bonding and embedded connection method further improves the performance of the cover. On the one hand, the sealant ensures the sealing of the interface between the upper cover 3 and base 1 and the glass cover 2, effectively preventing moisture, dust and other impurities from entering the cover, protecting the internal equipment from external environmental factors and extending the service life of the equipment. On the other hand, the embedded connection makes the combination of the upper cover 3 and base 1 and the glass cover 2 tighter and stronger, not only enhancing the overall strength of the cover, but also better dispersing stress when subjected to external impact, improving the impact resistance of the cover. At the same time, this unique design is also aesthetically pleasing, allowing the cover to meet functional requirements while blending into various environments and enhancing the overall visual effect.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
