Technical Field

[0001] The utility model relates to the technical field of high-speed underwater vehicle testing, in particular to a pop-up data recording device for a high-speed underwater vehicle model. Background Art

[0002] With the help of supercavitation drag reduction technology, high-speed underwater vehicles can reach a high speed of more than 200 kn, which is difficult for conventional fully wetted vehicles to achieve. In recent years, the research on this type of vehicle has shown a dominant trend from mechanism interpretation to application research. Therefore, experimental research on high-speed underwater vehicles has become an important stage in its development process. In this process, the success or failure of the recovery of the vehicle's experimental data determines the success or failure of the experiment. At present, due to the constraints of the development status of underwater communication technology, the experimental data collected by high-speed underwater vehicles during underwater navigation are all stored inside the vehicle body, so the recovery of high-speed underwater vehicle experimental data is mainly achieved by recovering the vehicle body.

[0003] At present, the experimental research on long-range high-speed underwater vehicles is mainly carried out in open natural waters such as lakes, reservoirs, and the sea. These experimental waters are often deep and have complex underwater terrain. In actual application, the recovery of the vehicle body is often costly, time-consuming and labor-intensive. In addition, after the vehicle is soaked in water for a long time, water may enter the interior, causing data damage and loss. Sometimes it cannot even be recovered, which seriously affects the recovery of experimental data and the normal progress of subsequent experimental plans. In view of the current actual experimental needs, it is necessary to design a device to realize the real-time recording of high-speed underwater vehicle test data, and to be able to separate from the vehicle after the recording is completed, so as to realize the reliable and separate recovery of test data. However, the various detachable data recording devices currently available on the market or in public materials cannot meet the test needs of high-speed underwater vehicle models in terms of structure or function.

[0023] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Installation process of this utility model:

[0025] See also Figure 1 A pop-up data recording device for a high-speed underwater vehicle model includes: a recorder component 1, a recorder component installation compartment component 2, and a pop-up system 3.

[0026] like Figure 1-Figure 3 As shown, the recorder assembly 1 includes: a recorder housing 101, a bracket sealing ring 102, a recorder internal bracket 103, a magnetic suction socket 104, a housing sealing ring 105, a data recording module 106, a strobe light 107, a self-locking relay fixing bracket 108, a battery 109, and a self-locking relay 110; the battery 109 is fixed to the recorder internal bracket 103 by screws, and is used to supply power to the internal devices of the recorder assembly 1; the strobe light 107 is fixed to the inner end surface of the recorder internal bracket 103 by screws; the self-locking relay The device 110 is fixed to the internal bracket 103 of the recorder through the self-locking relay fixing bracket 108, which is used to keep the internal circuit of the recorder component 1 closed; there are 3 data recording modules 106, which are used to record the aircraft data. When installed, they are inserted into the 3 slots of the internal bracket 103 of the recorder respectively; the magnetic socket 104 is fixed to the outer end surface of the internal bracket 103 of the recorder through threads, and after being attracted by the magnetic plug 202 installed on the recorder component installation compartment 201, the communication between the aircraft internal test system and the recorder component 1 is connected. After completing the installation of the above equipment, follow the steps as follows: Figure 7 The circuit diagram shown in the figure completes the internal circuit connection of the recorder assembly 1. Then, the bracket sealing ring 102 is installed into the sealing ring groove reserved in the internal bracket 103 of the recorder, and the internal bracket 103 of the recorder is assembled with the help of two symmetrically arranged blind holes on the outer end surface of the internal bracket 103 of the recorder to complete the assembly of the internal bracket 103 of the recorder and the recorder housing 101. Finally, the two housing sealing rings 105 are installed on the outer ring of the recorder housing 101. After the installation, the recorder assembly 1 is as shown in FIG. Figure 4 shown.

[0027] like Figure 1-Figure 2 As shown, the recorder assembly installation compartment component 2 includes: a recorder assembly installation compartment 201, a magnetic plug 202, and a quick-connect air nozzle 203; the magnetic plug 202 and the quick-connect air nozzle 203 are both installed on the partition of the recorder assembly installation compartment 201 through threads, and the quick-connect air nozzle 203 is used to introduce high-pressure gas into the recorder assembly installation compartment 201 when ejecting the recorder assembly 1.

[0028] After completing the assembly of the recorder assembly 1 and the recorder assembly installation compartment assembly 2, place the recorder assembly 1 in accordance with Figure 3 The recorder assembly 1 is installed in the recorder assembly installation compartment 201 in the direction shown. After installation, the two protruding cylinders inside the recorder assembly installation compartment 201 will be inserted into the two blind holes on the outer end surface of the recorder internal bracket 103. At this time, the magnetic suction socket 104 and the magnetic suction plug 202 can be correctly attracted, and the recorder assembly 1 will not rotate in the recorder assembly installation compartment 201 after installation, thereby avoiding damage to the magnetic suction plug or poor contact. During the installation of the recorder assembly 1 into the recorder assembly installation compartment 201, the air originally existing in the recorder assembly installation compartment 201 is squeezed and discharged from the quick-connect air nozzle 203. Then complete the line connection from the aircraft internal measurement system to the magnetic suction plug 202, and connect the air supply hose 304 to the quick-connect air nozzle 203. At this time, the remaining space in the recorder assembly installation compartment 201 will form a complete seal, which can ensure that the recorder assembly 1 will not accidentally fall off during the launch process, and at the same time, it can ensure that it can be ejected normally. Afterwards, the recorder assembly installation compartment 201 in which the recorder assembly 1 has been installed is connected to a preset position at the tail of the aircraft by means of threads.

[0029] After the other components of the aircraft are installed, refer to Figure 1 , Figure 5 , Figure 6 As shown, the connection of the ejection system 3 is completed: the high-pressure gas cylinder 301 equipped with the solenoid valve 302 is installed in the gas cylinder compartment, and the high-pressure gas cylinder 301 is filled with high-pressure air of a specified pressure according to the preset experimental water depth. After the filling is completed, the other end of the gas hose 304 is connected to the gas outlet of the solenoid valve 302 (one end of the gas hose 304 has been connected to the quick-connect gas nozzle 203 before), and finally the line connection between the solenoid valve 302 and the relay 303 is completed.

[0030] The action process of this utility model:

[0031] After the aircraft is loaded into the launch tube and powered on, the aircraft internal test system will send a control signal to the recorder component 1 to close the main contact of the self-locking relay 110 inside the recorder component 1 and self-lock, so that the data recording module 106 and the strobe light 107 inside the recorder component 1 are powered. After the data recording module 106 is powered, it enters a waiting state and can write data at any time. After the strobe light 107 is powered, it starts to flash at a fixed frequency. After the aircraft is launched into the water according to the preset program, the aircraft internal test system starts to write measurement data to the three data recording modules 106 in the recorder component 1 through three independent serial ports. After the data recording is completed, the internal measurement system of the aircraft sends a closing signal to the relay 303, which then opens the solenoid valve 302. After the solenoid valve 302 is opened, the gas path is connected, and the high-pressure gas inside the high-pressure gas cylinder 301 is released into the closed space between the recorder component installation compartment 201 and the recorder component 1 through the solenoid valve 302, the gas hose 304, and the quick-connect gas nozzle 203, thereby completing the ejection of the recorder component 1. When ejecting, the magnetic suction socket 104 and the magnetic suction plug 202 are forced to disengage, and the recorder component 1 separates from the aircraft and floats to the water surface, and the flashing of the strobe light 107 assists the salvage personnel in searching and salvaging. The test personnel can quickly export data from the recorder component 1 for analysis and processing.

[0032] The above are preferred embodiments of the present invention, but they cannot be simply understood as limitations of the present invention. Ordinary technicians in this field can modify, replace and deform the above embodiments within the scope of the present invention without departing from the principle or purpose of the present invention.
