[0002] With the exploration of the ocean by human beings, optoelectronic integrated wet-plug connectors are gradually being used. Optoelectronic integrated wet-plug connectors are optoelectronic integrated connectors that can be directly docked and separated at a depth of several thousand meters underwater. They are mostly used on fixed equipment on the seabed. When the connector is in use, the socket is installed on a docking box fixed on the seabed, and the plug is docked by an underwater robot. Since the underwater robot uses a propeller to dynamically suspend in the seawater, during the docking process of the plug and socket, the disturbance of the propeller will cause the seabed mud to roll. At the same time, the dynamic suspension of the underwater robot also changes the relative position of the plug and socket. Therefore, the docking environment of the plug and socket includes unfavorable factors such as mud and deviation of the plug.

[0037] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0038] Since optoelectronic integrated connectors are mostly connected to fixed equipment on the seabed for use, when an underwater robot docks with a connecting machine, the disturbance of the propeller causes the mud on the seabed to roll. At the same time, the robot is suspended in the seawater, causing the plug to be misaligned during docking and to be in a muddy environment. Therefore, in order to ensure the reliability of the connector during underwater docking and separation, it is necessary to simulate the turbid environment when the seabed mud is rolling during performance testing and perform misaligned docking and separation cycles on it. During this period, it is also necessary to monitor the connector performance in real time. How to quickly simulate different mud environments and misalignment deviations is a problem that the present invention needs to solve.

Turbidity pressure test device for photoelectric integrated wet plug connector testing

[0040] Combination Figure 1-2 As shown, the first aspect of the present invention proposes a technical solution, a turbidity pressure test device for testing an optoelectronic integrated wet plug connector, comprising a sealed test box 10, a pressurizing device 20, a first drive device 30, an electrical performance test device 40 and a second drive device 50. A test cavity is provided inside the sealed test box 10, and a male plug 41 and a watertight connector 43 are provided on the box wall of the sealed test box 10. The watertight connector 43 is connected to a female plug 42 through a watertight cable. The female plug 42 is driven by the second drive device 50 and the first drive device 30 to complete the plugging and unplugging actions of the male plug 41 and the female plug 42. The electrical performance test device 40 detects the electrical state of the male plug 41 and the female plug 42 after plugging.

[0041] The electrical performance test equipment 40 may be a contact resistance tester, a withstand voltage tester, an insulation resistance tester or other equipment for testing electrical performance, or an insertion loss tester or other optical performance tester, or multiple test equipment may be used simultaneously.

[0042] The sealing test box 10 comprises a cylinder 14 with openings at both ends. The two ends of the cylinder 14 are connected to a cover 13 . The cover 13 is provided with through holes 103 , 104 for the driving rod 32 to pass through. Sealing rings are provided in the through holes 103 , 104 .

[0043] In an alternative embodiment, in combination Figure 3-4 As shown, the cylinder 14 is a rectangular cylinder, and the cover 13 covers the first end and the second end of the cylinder 14 respectively. A sealing gasket is provided between the cover 13 and the cylinder 14, and the cover 13 and the cylinder 14 are fixed with bolts. In this way, the sealed test box 10 composed of the cover 13 and the cylinder 14 can withstand a pressure of 60Mpa to simulate the water pressure on the seabed.

[0044] A first fixing hole 101 for connecting a watertight connector 43 and a second fixing hole 102 for connecting a male plug 41 are provided on one of the covers 13. The plug-in portion of the male plug 41 is located in the sealed test box 10, and the signal line portion is located outside the sealed test box 10 and is connected to an electrical performance testing device 40. One end of the watertight connector 43 is connected to a signal cable, and the other end is connected to a watertight cable. The signal cable is located outside the sealed test box 10 and is connected to the electrical performance testing device 40. The watertight cable is connected to a female plug 42. When the male plug 41 and the female plug 42 are docked, a closed loop is formed. The electrical performance testing device 40 can test electrical properties such as resistance and withstand voltage and optical properties such as insertion loss.

[0045] Further, the pressure boosting device 20 is connected to the sealed test box 10 for boosting the pressure in the test cavity; optionally, the pressure boosting device 20 is a pressure boosting pump or a hydraulic pressure boosting device or a mechanical pressure boosting device.

[0046] A pressure gauge 11 is provided on the sealing test box 10 to monitor the increasing process and keep the pressure in the sealing test box 10 at a preset pressure.

[0047] Furthermore, the first driving device 30 includes a driving rod 32, the first end and the second end of the driving rod 32 both pass through the box wall of the sealing test box 10, that is, pass through the through holes 103 and 104, and the moving direction of the driving rod 32 is parallel to the plug-in direction of the male plug 41 and the female plug 42. The second driving device 50 has a first end connected to the driving rod 32, and the female plug 42 is connected to the second end of the second driving device 50.

[0048] Specifically, the first drive device 30 includes a motor, the output end of the motor is connected to the screw rod 31, and the second end of the screw rod is connected to the drive rod 32 through a coupling. When the motor rotates forward, the drive rod 32 moves to the left, and when the motor rotates reversely, the drive rod 32 moves to the right.

[0049] In this way, when the first driving device 30 drives the driving rod 32 to move, the female plug 42 performs a plugging and unplugging action relative to the male plug 41, thereby completing the docking and unplugging of the male and female plugs.

[0050] Meanwhile, the driving rod 32 will not cause the volume change in the sealed test box 10 when it moves, so the water pressure in the sealed test box 10 is stable to ensure the test effect.

[0051] Furthermore, in order to simulate the propeller disturbance environment on the seabed, the sealed test box 10 is filled with a water medium containing mud and sand. A propeller 12 is also provided in the sealed test box 10. The propeller 12 is configured to rotate at a predetermined speed to make the mud and sand flow in the sealed test box 10. The second driving device 50 is configured to drive the axis of the female plug 42 to deviate from the axis of the male plug 41.

[0052] In this way, when the male and female plugs are connected, there is flowing mud and sand in the surrounding water environment, and the female plug 42 also undergoes relative displacement to simulate the water environment during the actual connection process of the male and female plugs.

[0053] In order to simulate the extreme performance of the male and female plugs, the sediment flow rate in the sealing test box 10 and the deviation of the female plug 42 relative to the male plug 41 change according to a predetermined threshold value, and each time the preset value changes, the driving rod 32 drives the female plug 42 and the male plug 41 to complete the plug-in and unplug action.

[0054] Sediment environment simulation

[0055] In an optional embodiment, the bottom layer of the sealed test box 10 is paved with a 5 mm thick mud-sand mixture, the particles of the mud-sand are between 100 um and 1 mm, the rotation speed of the propeller 12 is 100 r / min-300 r / min, and the maximum offset distance of the female plug 42 is 10 mm.

[0056] Specifically, the rotation speed of the propeller 12 and the offset of the female plug 42 are divided into 10 levels, and two plug-in tests are performed for each level. Among them, only the test of the sediment flow rate or the test of the plug-in offset can be performed separately.

[0057] Furthermore, since mud and sand have a probability of entering the mating surfaces of the male and female plugs, the flowing water may also interfere with the female plug 41 to deviate from the axis of the male plug 41. Moreover, since the faster the water flow rate, the greater the mud and sand content, the more unstable the suspension of the underwater robot, and the greater the deviation of the female plug, the mud and sand content and the deviation of the female plug should have a greater correlation.

[0058] The deviation of the female plug 42 relative to the male plug 41 is positively correlated with the rotation speed of the propeller 12. Therefore, the sediment flow rate and the plug offset can be tested simultaneously. Specifically, the first level of sediment flow rate corresponds to the first level of plug offset, and two plug tests are performed for each level.

[0059] In an optional embodiment, the docking position of the male plug 41 and the female plug 42 is defined as the plug-in position, the propeller 12 is arranged below the plug-in position, and the axis of the propeller 12 passes through the plug-in position. In this way, it can be ensured that when the propeller 12 rotates, the mud and sand on the bottom layer of the sealing test box 10 are blown into the plug-in position to affect the plug-in.

[0060] The propeller 12 is arranged at the bottom of the sealing test box 10, and the propeller 12 is oriented toward the box wall, wherein the propeller 12 drives the mud and sand to flow along the B direction or the C direction, wherein the B direction is parallel to the axial direction of the male plug 41, and the C direction is perpendicular to the axial direction of the male plug 41.

[0061] Combination Figure 3 As shown, in a specific embodiment, two propellers 12 are arranged at the bottom of the sealing test box 10. When the axial directions of the two propellers 12 are toward direction B and the two propellers 12 have the same direction of rotation, the water flows in the direction shown in the figure, and the water flow near the plug-in position contains mud and sand particles, and the mud and sand move downward to the plug-in position.

[0062] Combination Figure 4 As shown, when the axial directions of the two propellers 12 are toward direction B and the two propellers 12 are turned in opposite directions, the water flows in the direction shown in the figure, and the water near the plug-in position contains mud and sand particles, and the mud and sand move upward to the plug-in position.

[0063] Female plug offset simulation

[0064] Further, the axis of the female plug 42 is defined as axis W, the axis of the male plug 41 is defined as axis U, and the deviation of the female plug 42 relative to the male plug 41 includes the deviation angle between the axis W and the axis U and the radial deviation.

[0065] Preferably, the second driving device 50 includes a collar 51, a driver 53, a connecting rod 52 and a fixing frame 54, the female plug 42 is connected to the fixing frame 54 through the fixing rod 421, the collar 51 is fixed to the outer wall of the driving rod 32, and the driver 53 is used to drive the connecting rod 52 to rotate around the axis of the driving rod 32, or the driver 53 is used to drive the fixing frame 54 to move relative to the connecting rod 52 along the length direction of the connecting rod 52.

[0066] The fixing frame 54 is a frame, and one end of the fixing rod 421 away from the female plug 42 is connected to a protrusion 422 , and the protrusion 422 is fixed to the fixing frame 54 .

[0067] When the female plug 42 is angularly offset relative to the male plug 41, the female plug 42 should be controlled to rotate around the axis of the driving rod 32 at a predetermined angle. Figure 7 As shown, the driver 53 includes an annular motor connected to the outer wall of the collar 51 , a first end of a connecting rod 52 is fixed to the outer wall of the annular motor, and a fixing bracket 54 is connected to the second end of the annular motor.

[0068] In this way, when the annular motor rotates, the fixing frame 54 can be controlled to deviate from the axis of the male plug 41, thereby achieving an offset between the female plug and the male plug.

[0069] In other embodiments, in combination Figure 5-6As shown, the driver 53 includes a watertight motor 531, a rack 532 and a sleeve 533. The sleeve 533 is fixed to the outer wall of the watertight motor 531, the rack 532 is set to the inner wall of the sleeve 533, the bottom of the rack 532 is connected to the fixed frame 54, and the output end of the watertight motor 531 is connected to a worm gear, which is engaged with the rack 532, so that the rack 532 slides in the sleeve 533.

[0070] In this way, when the watertight motor 531 rotates, it can drive the worm gear to engage with the rack 532, so that the rack 532 moves along its length direction, such as the up and down directions as shown in the figure, thereby realizing the downward or upward movement of the female plug 42 to deviate from the axis of the male plug 41.

[0071] In combination with the above embodiments, when the driver 53 is in operation, it will not cause a change in the water pressure of the sealed test box 10, and the water pressure environment is kept stable.

Test method for optoelectronic integrated wet plug connector

[0073] The second aspect of the present invention provides a technical solution, a method for testing an optoelectronic integrated wet plug connector, using the above-mentioned turbid pressure test device for testing an optoelectronic integrated wet plug connector, comprising the following steps:

[0074] Step 1: Pressurize the test cavity by the pressure boosting device 20 so that the pressure in the test cavity reaches a preset value;

[0075] Step 2, setting the speed parameter of the propeller 12 and the deviation parameter of the female plug 42 relative to the male plug 41;

[0076] Step 3, the female plug 42 and the male plug 41 are plugged in and out, and the electrical performance of the female plug 42 and the male plug 41 in the plugged state is tested by the electrical performance testing equipment 40;

[0077] Among them, the rotation speed of the propeller 12 is divided into n levels, and the deviation of the female plug 42 relative to the male plug 41 is divided into m levels, wherein n is greater than or equal to m. When the deviation of the female plug 42 relative to the male plug 41 changes by one level, the female plug 42 and the male plug 41 complete at least one plugging and unplugging action.

[0078] In an optional embodiment, a layer of 5mm thick mud-sand mixture is laid on the bottom of the sealing test box 10, and the particles of the mud-sand are between 100um-1mm. The speed of the propeller 12 is 100r / min-300r / min, and the maximum offset distance of the female plug 42 is 10mm.

[0079] Specifically, the sediment flow rate and the plug offset are related to the test. The rotation speed of the propeller 12 is divided into 20 levels, and the offset of the female plug 42 is divided into 10 levels. For each level of offset of the female plug 42, the propeller 12 changes two levels, and two plug tests are performed for each level.

[0080] In other embodiments, only the sediment flow rate test or the plug offset test may be performed separately.

[0081] In combination with the above embodiments, the present invention arranges a propeller in a sealed test box, and pre-places a layer of mud and sand in the box. The rotation of the propeller disturbs the water flow, so that the water flow carries the mud and sand. At the same time, a second driving device is arranged on the driving rod that drives the female plug to perform the plugging and unplugging action, which can drive the female plug to deviate from the axis of the male plug, so that the male plug and the female plug are misaligned when plugged in. In this way, whether the plugging of the watertight plug in the seabed environment is reliable under the conditions of mud and sand and misalignment can be simulated.

[0082] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
