[0002] Except for small aircraft, all aircraft in the aviation industry are equipped with a CVFDR (CV cabin voice flight data recorder, commonly known as a black box), which is mainly used for aircraft crash search and rescue and post-accident investigation. Among them, the ULB (underwater beacon) is an important component of the CVFDR. Its function is to be activated after encountering water and continuously transmit low-frequency radio signals for use in marine search and rescue.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: Currently, in the actual work of testing, the existing technology involves holding a wire by hand to short-circuit the hydroelectric valve and the bottom positioning hole of the underwater positioning beacon. Hand operation is prone to poor contact and disconnection, resulting in intermittent pulse signals. Moreover, the hand can also obstruct the signal, making the received signal unstable. The triggering time needs to be extended to confirm the signal. The testing process consumes too much power, reduces the effective installation time, increases the number of replacements, and wastes manpower and aviation materials.

[0004] Therefore, those skilled in the art have provided a device for testing ULB underwater positioning beacons to solve the problems mentioned in the background art. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-2 and Figure 5 The present invention provides an embodiment of a device for testing ULB underwater positioning beacons, comprising a device clip 3 for placing positioning beacons and a computer 8 for receiving information. The device clip 3 includes a base plate 301, and side plates 302 are fixedly provided on both sides of the base plate 301. Each of the two side plates 302 has a mounting groove 9 on its opposite side. Locking components 2 for restricting positioning beacons are installed on the inner walls of the front and rear ends of the two mounting grooves 9. Electrode blocks 10 are embedded in one side of the inner wall of each of the two mounting grooves 9, and the two electrode blocks 10 are connected to a digital multimeter 6 through leads 5. An SDR device 7 for receiving positioning beacon frequency signals is plugged into the computer 8.

[0024] Specifically, the testing equipment can clamp and fix the positioning beacon, and connect it to a digital multimeter 6 via its built-in lead 5. The digital multimeter's voltage range has an internal resistance greater than 10 megohms, used for equivalent voltage measurement. The positioning beacon is controlled by a remote control switch and operates based on an SDR device 7, which uses software-defined radio technology to receive frequency signals and play sound signals on a computer 8. This enables waveform monitoring and audio recording, effectively recording the sound signal and transmission duration. The entire process can be completed by a single person, making it simple and convenient.

[0025] SDR device 7 is a device based on radio broadcast communication technology. It is based on a software-defined wireless communication protocol rather than hard-wired. This technology is known and will not be described in detail here.

[0026] Reference Figures 1-3 The two mounting slots 9 are embedded with positioning beacon bodies 1 and the two ends of the positioning beacon bodies 1 are electrically connected to the electrode blocks 10 respectively. The digital multimeter 6 is used to measure the open circuit voltage of the positioning beacon bodies 1.

[0027] Specifically, the electrode block 10 set inside the mounting slot 9 is connected to both ends of the positioning beacon body 1 to realize the connection of the battery inside the positioning beacon body 1, thereby realizing the detection and use after the open circuit voltage is energized.

[0028] Reference Figures 1-4 The locking assembly 2 includes a linkage block 206. A toggle block 201 is fixedly installed on one side of the upper surface of the linkage block 206. A spring 202 is fixedly installed at one end of the linkage block 206 near the toggle block 201 and a fixing plate 205 is fixedly installed at the other end. A locking block 203 is fixedly installed on one side of the fixing plate 205 away from the linkage block 206 via a connecting rod 204. The locking assembly 2 is embedded in the side plate 302.

[0029] Specifically, during use, the positioning beacon body 1 is inserted into the mounting slot 9 from top to bottom. During the process of pressing down the positioning beacon body 1, the positioning beacon body 1 exerts a squeezing force on the locking block 203. After being squeezed, the locking block 203 retracts inward, causing the connecting rod 204 at one end to push the fixing plate 205, the linkage block 206, and the tension spring 202. After the positioning beacon body 1 has completely passed through the locking block 203, the spring 202 is no longer under force and retracts to reset, thereby achieving the automatic reset and self-locking effect of the locking block 203, and realizing the auxiliary restriction effect on the positioning beacon body 1.

[0030] Reference Figures 1-4 The upper end of the side plate 302 has a movable groove 4 at the front and rear ends. The linkage block 206 is slidably embedded in the movable groove 4. The actuating block 201 passes through the upper end of the movable groove 4. The end of the spring 202 away from the linkage block 206 is fixedly installed on one end of the inner wall of the movable groove 4.

[0031] Specifically, a movable groove 4 is reserved at the upper end, and the toggle block 201 and the linkage block 206 at the lower end are both located inside the movable groove 4, so that they can move smoothly during use. At the same time, the toggle block 201 at the upper end can be manually pressed and pulled when the positioning beacon body 1 is disassembled or assembled, so as to manually move the locking block 203 laterally, thereby releasing the restriction effect on the positioning beacon body 1.

[0032] Reference Figures 1-4 One end of the locking block 203 penetrates the inner wall of the side plate 302 and is located inside the mounting groove 9. The upper surface of the end of the locking block 203 located inside the mounting groove 9 is an arc surface.

[0033] Specifically, by utilizing the arc-shaped structure on the upper end of the locking block 203, the positioning beacon body 1 can push the locking block 203 to move in translation when it contacts and squeezes the locking block 203, thus quickly completing the installation operation of the positioning beacon body 1 without manual adjustment.

[0034] Working principle: When in use, the positioning beacon body 1 is first embedded into the inner side of the device clamp 3, that is, the two ends of the positioning beacon body 1 are respectively embedded in the two mounting slots 9, and the locking component 2 at the upper end of the mounting slot 9 restricts and fixes the positioning beacon body 1.

[0035] Secondly, a digital multimeter 6 is connected via its built-in lead 5. The voltage range of the digital multimeter has an internal resistance greater than 10 megohms, which is used for equivalent voltage measurement. The positioning beacon is controlled by a remote control switch and based on the SDR device 7, which uses software radio technology to receive frequency signals and play sound signals on the computer 8. This enables waveform monitoring and audio recording, effectively recording the sound signal and transmission duration.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
