Description

Technical Field

[0001] This utility model relates to the field of radome manufacturing technology and discloses a radome strength testing device. Background Technology

[0002] A radome is an external shell that protects an antenna system. It is usually made of wave-transparent materials, such as composite materials, fiberglass, or ceramics. It can provide physical protection and environmental isolation for the antenna without affecting the transmission of electromagnetic waves. Its structural strength and airtightness directly affect the signal transmission quality and equipment reliability of antenna systems in fields such as communications, radar, and aerospace.

[0003] To ensure the performance of the radome, rigorous strength tests are required during the manufacturing process, mainly including mechanical strength tests, environmental adaptability tests, and airtightness tests. During airtightness testing, the radome must be reliably restrained. Existing mechanical clamps or simple support structures typically provide single-point restraint, fixing the upper or lower part of the radome. This method of fixing can easily cause the radome to loosen during testing, leading to gas leakage and affecting the test results.

[0004] Therefore, there is a need for a radome strength testing device with dual upper and lower limit functions. Utility Model Content

[0005] To overcome the shortcomings of existing testing devices that typically provide single-point limiting to fix the upper or lower part of the radome, which can easily lead to the radome loosening during testing and causing gas leakage that affects the test results, this invention provides a radome strength testing device with dual upper and lower limiting functions.

[0006] Technical Solution: A radome strength testing device includes a base, a control panel, a test chamber, hinges, a protective door, a placement platform, a fixing structure, a second air pump, a second air supply pipe, a gas pressure gauge, and a gas guide pipe. The control panel is located on the front of the base, and the test chamber is mounted on the top of the base. Multiple hinges are installed on the front of the test chamber, and the protective door is mounted on all the hinges. A placement platform is fixedly connected to the bottom of the test chamber, and a fixing structure is provided on the placement platform to fix the radome to the platform. The second air pump is installed inside the base and is linearly connected to the control panel. Two second air supply pipes are connected and connected to the left side of the second air pump. Two gas supply pipes are connected at the top of each other, with a gas pressure gauge electrically connected to the control panel. A gas guide pipe is connected to the top of the gas pressure gauge and passes through the placement platform. The platform also includes a limit ring, a fixed seat, a sliding rod, a pressure ring, and a first elastic element. The limit ring is fixedly connected to the top of the placement platform and can contact the surface of the radome. Fixed seats are fixedly connected to both the left and right sides inside the test chamber. Sliding rods are slidably installed on the fixed seats. A pressure ring is fixedly connected to the bottom of the two sliding rods and can press the radome tightly. A first elastic element is sleeved on the sliding rod and its two ends are connected to the fixed seat and the pressure ring, respectively.

[0007] In a preferred embodiment of the present invention, the fixing structure includes an airbag, a first air pump and a first air supply pipe. An air guide groove is provided inside the placement platform, and an airbag is provided on the outside of the placement platform. The air guide groove is connected to the airbag. The first air pump is installed inside the base. The first air pump is electrically connected to the control panel. The first air supply pipe is connected to and communicates with the left side of the first air pump. The first air supply pipe is connected to the air guide groove.

[0008] In a preferred embodiment of the present invention, the test chamber further includes a limiting seat, a guide seat, a limiting rod, and a second elastic element. The limiting seat is fixedly connected to the front side of the test chamber. Two slots are provided on the front side of the limiting seat. Two guide seats are installed on the front side of the protective door. Two limiting rods are slidably arranged on the two guide seats. The left end of the limiting rod is engaged with the slot. A second elastic element is connected between the two limiting rods.

[0009] In a preferred embodiment of the present invention, a handle is also included, with a handle fixedly connected to each of the two limiting rods, and the two handles are vertically aligned.

[0010] In a preferred embodiment of the present invention, a sealing ring is also included. The sealing ring is adhered to the front side of the test chamber and is in close contact with the rear side of the protective door.

[0011] In a preferred embodiment of the present invention, a rubber ring is also included, with the rubber ring adhered to the inner wall of the limiting ring and in contact with the surface of the antenna cover.

[0012] In a preferred embodiment of this invention, the protective door is made of tempered glass.

[0013] In a preferred embodiment of this utility model, a handle is installed on the front side of the protective door.

[0014] Compared with the prior art, the present invention provides an antenna radome strength testing device with the following advantages: 1. The limiting ring contacts the lower surface of the antenna radome to provide initial limiting. Then, the pressure ring is released, and the first elastic element rebounds to push the slide rod and the pressure ring downward, so that the pressure ring presses the upper part of the antenna radome, forming a double limiting with the limiting ring, preventing the antenna radome from loosening and causing gas leakage that affects the test results.

[0015] 2. By loosening the limit rod, the second elastic element returns to its original state, pushing the limit rod outward to re-engage with the slot, thereby locking the protective door and ensuring the stability of the test chamber during the test, preventing the protective door from loosening.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0023] Example 1: A radome strength testing device, please refer to... Figures 1-4The system includes a base 1, a control panel 101, a test chamber 2, hinges 3, a protective door 4, a placement platform 5, a fixing structure, a second air pump 10, a second air supply pipe 11, a gas pressure gauge 1101, and a gas guide pipe 12. The control panel 101 is located on the front of the base 1, and the test chamber 2 is mounted on the top of the base 1. Three hinges 3 are mounted on the front of the test chamber 2, and the protective door 4 is mounted on all three hinges. The placement platform 5 is fixedly connected to the bottom of the test chamber 2, and a fixing structure is provided on the placement platform 5. The fixing structure is used to fix the radome to the placement platform 5, and includes an airbag 6, a second air supply pipe 10, a second air supply pipe 11, a gas pressure gauge 1101, and a gas guide pipe 12. An air pump 8 and a first air supply pipe 9 are provided. An air guide groove 501 is provided inside the placement platform 5. An air bag 6 is provided on the outside of the placement platform 5. The air guide groove 501 communicates with the air bag 6. The first air pump 8 is installed inside the base 1 and is electrically connected to the control panel 101. The first air pump 8 is connected to and communicates with the first air supply pipe 9 on its left side. The first air supply pipe 9 communicates with the air guide groove 501. A second air pump 10 is installed inside the base 1 and is electrically connected to the control panel 101. Two second air supply pipes 11 are connected to and communicate with the left side of the second air pump 10. The tops of the two second air supply pipes 11 share a common feature. A gas pressure gauge 1101 is electrically connected to a control panel 101. A gas guide tube 12 is connected to and communicates with the top of the gas pressure gauge 1101, passing through a placement platform 5. A limit ring 7 is fixedly connected to the top of the placement platform 5, allowing it to contact the radome surface. Fixing seats 13 are fixedly connected to both the left and right sides inside the test chamber 2. Sliding rods 14 are slidably mounted on the fixing seats 13. A pressure ring 15 is fixedly connected to the bottom of both sliding rods 14, pressing the radome tightly. A first elastic element 16 is sleeved on each sliding rod 14. The first elastic element 16... The ends are respectively connected to the fixed base 13 and the pressure ring 15. A sealing ring 23 is bonded to the front side of the test chamber 2. The sealing ring 23 is in close contact with the rear side of the protective door 4. The sealing ring 23 reduces the gap between the protective door 4 and the test chamber 2, increasing airtightness. A rubber ring 24 is bonded to the inner wall of the limiting ring 7. The rubber ring 24 is in contact with the surface of the radome, preventing the limiting ring 7 from directly contacting the surface of the radome and causing scratches. The protective door 4 is made of tempered glass, which enhances durability and allows you to see the inside of the test chamber 2. A handle is installed on the front side of the protective door 4. The handle is used to increase the point of force and facilitate the rotation of the protective door 4.

[0024] When testing the radome, first turn the protective door 4 forward to open the test chamber 2. Then push the pressure ring 15 upward, causing the slide bar 14 to move upward and compress the first elastic element 16. After placing the radome on the placement platform 5, start the first air pump 8 through the control panel 101. The first air pump 8 operates, filling the airbag 6 through the first air supply pipe 9 and the air guide groove 501, causing the airbag 6 to inflate and adhere tightly to the inner wall of the radome, thereby fixing the radome. After fixing, turn off the first air pump 8. At this time, the limiting ring 7 contacts the lower surface of the radome, providing initial limiting. Subsequently, release the pressure ring 15, and the first elastic element 16 rebounds, pushing the slide bar 14 and the pressure ring 15 downward, causing the pressure ring 15 to press against the upper part of the radome, forming a double limiting with the limiting ring 7 to prevent damage during testing. If there is an air leak or the radome is detached, turn the protective door 4 backward to close the test chamber 2. Start the second air pump 10 and the gas pressure gauge 1101 through the control panel 101. The second air pump 10 will inject gas into the radome through the second gas supply pipe 11 and the gas guide pipe 12. The gas pressure gauge 1101 will monitor the gas pressure in real time. The monitored data will be displayed through the control panel 101. By adjusting the gas pressure and observing the changes in the radome, its strength can be effectively tested. After the test, turn off the second air pump 10 and stop the gas injection. Turn the protective door 4 forward again to open the test chamber 2. Push the pressure ring 15 upward to release the limit. If the airbag 6 is still inflated, the first air pump 8 needs to be used to extract the gas to make the airbag 6 contract. Finally, remove the radome from the placement platform 5.

[0025] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 5 The front of the test chamber 2 is fixedly connected to a limiting seat 17. Two slots 18 are opened on the front of the limiting seat 17. Two guide seats 19 are installed on the front of the protective door 4. Two limiting rods 20 are slidably set on the two guide seats 19. The left end of the limiting rod 20 is engaged with the slot 18. A second elastic element 21 is connected between the two limiting rods 20. A handle 22 is fixedly connected to each of the two limiting rods 20. The two handles 22 are vertically aligned. By squeezing the two handles 22, the two limiting rods 20 can be pushed inward at the same time, so as to quickly release the lock on the protective door 4.

[0026] When it is necessary to open the test chamber 2, first push the limiting rod 20 inward to compress the second elastic element 21 and disengage it from the slot 18, thus releasing the lock on the protective door 4. Then, rotate the protective door 4 forward to open the test chamber 2. After placing the antenna cover in the designated position, rotate the protective door 4 backward to close the test chamber 2. At this time, release the limiting rod 20, and the second elastic element 21 returns to its original state. Push the limiting rod 20 outward to re-engage it with the slot 18, thereby locking the protective door 4. This ensures the stability of the test chamber 2 during the test and prevents gas leakage caused by the loose protective door 4 from affecting the test results.
