Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to a rotatable water-cooled support for wave transmission testing. Background Technology

[0002] Existing wave-transmitting test supports suffer from numerous technical defects, severely impacting test accuracy and equipment safety. First, the harsh environment of high-enthalpy plasma flow fields means traditional supports cannot provide effective thermal protection for the transmitting and receiving antenna horns mounted at the front and rear. This makes the delicate antenna equipment susceptible to thermal damage, affecting not only test accuracy but also shortening equipment lifespan. Second, limited by wind tunnel structural design, when the wind tunnel flow field and the wave-transmitting plate have an angle of attack, traditional fixed supports cannot adjust the installation angle of the wave-transmitting material. This results in the antenna horns on both sides of the plate not being perfectly parallel, severely affecting the accuracy of wave-transmitting performance testing.

[0003] Furthermore, existing supports lack specialized heat insulation design, and the heat transfer path is not optimized, which can easily lead to excessively high overall temperatures and affect the normal operation of the testing equipment. The installation and fixing methods for the microwave-transparent material specimens are also relatively simple, which cannot ensure the stability of the specimens under the impact of high-speed airflow, making them prone to displacement or vibration, further reducing the testing accuracy.

[0004] Therefore, to address the above shortcomings, a rotatable water-cooled support is needed for wave transmission testing. Utility Model Content

[0005] (a) Technical problems to be solved The technical problem to be solved by this invention is to address the issue that the support causes the flow field and the wave-transparent material to have an angle of attack and poor heat insulation and heat dissipation effects.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides a rotatable water-cooled support for wave transmission experiments, including a rotating base, a water-cooled chamber, a rear panel, a heat insulation plate, and a front panel. The water-cooled chamber is rotatably connected to the rotating base and contains an antenna horn. The rear panel is embedded in the open end of the water-cooled chamber and has a square protrusion in the middle to hold a flat wave transmission model. The heat insulation plate is fixed to one side of the front panel, and the front panel is fixed to the water-cooled chamber. The heat insulation plate is attached to the rear panel to press and fix the model. The water-cooled chamber rotates so that the end face of the model extending to the window of the front panel is parallel to the direction of the high-enthalpy plasma flow field.

[0007] As a further explanation of this utility model, preferably, the rotating seat is cylindrical, and a turntable is fixedly connected to the top of the rotating seat. The turntable has several arc-shaped holes, and the turntable has a scale at the arc-shaped holes.

[0008] As a further explanation of this utility model, preferably, a stepper motor is provided on one side of the top of the rotating base, and a pulley and belt are rotatably connected to the output end of the stepper motor. The water-cooled chamber is mounted on the rotating base, and a gear set and a pulley are rotatably connected to the bottom of the water-cooled chamber. The belt of the pulley on the stepper motor is sleeved on the pulley below the water-cooled chamber to be rotatably connected to the rotating base.

[0009] As a further explanation of this utility model, preferably, the rear panel is a square plate structure, and the rear panel is provided with a flow path that communicates with the flow path in the water-cooled chamber.

[0010] As a further explanation of this utility model, preferably, the heat insulation plate has a square plate structure, and the outer diameter of the heat insulation plate is the same as the outer diameter of the front panel.

[0012] As a further explanation of this utility model, preferably, a perforated flange is provided outside the open end of the water-cooled chamber, and the front panel end face contacts the flange to be fixed to the flange by bolt pair.

[0013] As a further explanation of this utility model, preferably, the front panel is provided with a flow path, and a number of front panel water pipes are fixedly connected at intervals at the end face of the front panel connected to the flange.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A rotatable water-cooled support for wave transmission testing, combined with Figure 3 , Figure 4 It includes a rotating base 1, a water-cooled chamber 2, a rear panel 3, a heat insulation plate 4, and a front panel 5. The water-cooled chamber 2 is rotatably connected to the rotating base 1. The rear panel 3 is embedded in the open end of the water-cooled chamber 2. The heat insulation plate 4 is fixed to one side of the front panel 5. The front panel 5 is fixed to the water-cooled chamber 2.

[0021] Combination Figure 1 , Figure 5The rotating base 1 is cylindrical, with a square plate with connecting holes at its bottom for fixing the support. A circular turntable 11 is fixed to the top of the rotating base 1, with four arc-shaped holes and graduations at the arc-shaped holes. A bolt pair is located at the bottom of the water-cooled chamber 2, passing through the arc-shaped holes on the turntable 11 to achieve a rotatable connection with the rotating base 1. Simultaneously, the orientation of the water-cooled chamber 2 in the horizontal plane can be manually adjusted by visually inspecting the graduations to ensure that the end face of the wave-transparent plate model is parallel to the direction of the high-enthalpy plasma flow field. Alternatively, an automatic adjustment scheme can be adopted: a stepper motor is located on one side of the top of the rotating base 1, with a pulley and belt rotatably connected to its output. The water-cooled chamber 2 is mounted on the rotating base 1, and a gear set and pulley are rotatably connected to its bottom. The belt of the pulley on the stepper motor is fitted onto the pulley below the water-cooled chamber 2 for a rotatable connection with the rotating base 1. On the one hand, it can automatically control the precise rotation of the water-cooled chamber 2, and on the other hand, it can reduce the damage caused by high temperature conduction to the stepper motor.

[0022] Combination Figure 2 , Figure 4 The water-cooled chamber 2 is a square shell open on one side. The antenna horn can be placed inside the water-cooled chamber 2. Flow channels are provided in the inner wall of the water-cooled chamber 2. The rotating base 1 is hollow inside. Rear plate water pipes 12 are provided on both sides of the bottom of the rotating base 1 and on the bottom of the water-cooled chamber 2. The rear plate water pipes 12 are vertical or horizontal in their length direction and communicate with the flow channels inside the water-cooled chamber 2 and the rear panel 3. Cooling water or cooling compressed air is introduced into the water-cooled chamber 2 to reduce the temperature inside the water-cooled chamber 2, preventing damage to the antenna horn due to high temperature. A perforated flange 21 is provided on the open end of the water-cooled chamber 2. The end face of the front panel 5 contacts the flange 21 and is fixed to the flange 21 by bolts.

[0023] Combination Figure 3 , Figure 4 The rear panel 3 is a square plate structure made of stainless steel, with a complete water-cooling circulation path inside that connects to the flow path within the water-cooling chamber 2. The carefully designed flow channel distribution of the water-cooling circulation path effectively removes heat, maintaining the temperature of the rear panel 3 within a safe range. This provides reliable thermal protection for the receiving antenna horn installed at the rear, ensuring the normal operation of precision testing equipment in a high-temperature plasma environment. A square frame-like protrusion 31 is located in the center of the rear panel 3 for inserting a flat, transparent wave model 6.

[0024] Combination Figure 1 , Figure 4The heat insulation panel 4 is a square plate structure made of high-silica composite material, but it can also be made of alumina fiber composite material or other high-temperature resistant heat insulation materials. The dimensions of the heat insulation panel 4 perfectly match the front panel 5. The heat insulation panel 4 has a dual function: firstly, through its precise fit with the front panel 5, it completely fixes the model 6 in place, preventing displacement under high-speed airflow; secondly, it acts as an effective heat insulation barrier, preventing heat transfer to the rear and protecting the antenna horn and testing equipment at the rear. High-silica composite material has excellent high-temperature resistance and low thermal conductivity, making it an ideal choice for heat insulation materials.

[0025] Combination Figure 1 , Figure 2 The front panel 5 is a square plate structure made of oxygen-free copper. Copper-chromium-zirconium alloy or other high thermal conductivity alloys can also be used instead of oxygen-free copper. The front panel 5 has a hollow structure design or also has flow paths. Several front panel water pipes 51 are fixedly connected at intervals at the end face of the front panel 5 connected to the flange 21. The length of the front panel water pipes 51 is horizontal and communicates with the flow paths inside the front panel 5. A special groove is machined in the central part, which can accurately embed a 120mm model 6 and expose it. Alternatively, it can be adjusted to 80mm, 100mm, 150mm, etc., to accommodate different sizes of microwave-transparent material specimens. The edge of the groove has a small stepped structure, allowing the model 6 to be completely embedded in the middle of the front panel 5, ensuring installation stability and sealing. Oxygen-free copper is preferred because it has excellent thermal conductivity, enabling rapid conduction and dissipation of heat, effectively protecting the microwave-transparent material from excessive thermal shock. Furthermore, the excellent thermal conductivity of oxygen-free copper, the good thermal insulation of high-silica composite materials, and the corrosion resistance and water-cooling properties of stainless steel form a complementary material combination, achieving the optimization of the functions of each component.

[0026] A three-layer protection system is formed through the heat conduction and dissipation of the front panel 5, the thermal blocking of the heat insulation plate 4, and the water cooling protection of the rear panel 3, providing comprehensive and reliable thermal protection for the antenna horn. The rotatable angle adjustment function breaks through the limitations of traditional fixed designs, achieving free angle adjustment through a precise rotatable base, completely solving the problem of the angle of attack of the flow field and the wave-transmitting material. Preferably, the integrated design of the front panel 5, heat insulation plate 4, rear panel 3, and water cooling system not only simplifies the installation and use process but also significantly improves the reliability and stability of the system.

[0027] In summary, this utility model, through its innovative design concept and advanced technical solution, has achieved significant improvements in several aspects: 1. In terms of equipment protection capabilities: The three-layer protection design effectively protects the antenna horn from high-temperature plasma damage, effectively extends the service life of the equipment, effectively reduces maintenance costs, and brings considerable economic benefits to users.

[0028] 2. In terms of testing accuracy: The rotatable design completely solves the angle adjustment problem, ensuring that the antenna and horn are perfectly parallel, improving the accuracy of wave transmission performance testing, and significantly improving the reproducibility of test data, providing more reliable data support for scientific research. The adjustable angle function allows the support to adapt to different wind tunnel structures and flow field conditions, greatly expanding the scope of application of the test and improving the versatility and applicability of the equipment.

[0029] 3. Ease of Operation: The integrated design reduces installation and debugging steps, making operation more convenient and shortening test preparation time by approximately 25%, thus improving test efficiency. The dedicated slot and step design ensures reliable fixation of the wave-transparent material, controlling displacement within ±0.1mm under high-speed airflow conditions, significantly enhancing structural stability.

[0030] 4. Thermal Management Effectiveness: The rational material selection and structural design significantly improve the overall thermal management efficiency of the support, reducing the antenna operating temperature by tens of degrees Celsius and creating favorable conditions for the long-term stable operation of the equipment. Compared with traditional supports, this invention has significant advantages in equipment protection, testing accuracy, and ease of operation, providing a more reliable and accurate experimental platform for the study of wave transmission performance in high-enthalpy plasma environments.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
