Description

Technical Field

[0001] The present invention relates to the technical field of underwater connectors, and in particular to a dynamic pressure impact composite dynamic testing system and a testing method for wet plug-in connectors. Background Art

[0002] With the exploration of the ocean by human beings, wet-plug connectors are gradually used. For example, wet-plug connectors are installed on underwater robots and fixed facilities on the seabed. Wet-plug connectors are a type of connector that can be directly docked and separated at a depth of thousands of meters underwater. To ensure its reliability, its mating / separation mechanical life at the depth of water is required to be tested during performance testing.

[0003] In addition, when an underwater robot hits a foreign object while floating, or when an anchor, marine debris, dead fish, etc. hits a wet-plug connector, it may cause changes in the pressure at the connector contact point, thereby affecting the contact resistance. When the contact resistance changes significantly, it may cause the interruption of the electrical signal. In addition, if there are defects in the design or manufacture of the connector, such as poor contact, material problems, etc., it may also increase the risk of instantaneous power outages.

[0004] This electrical interruption will cause the electrical signal to be interrupted in a very short time. Although this interruption is short-lived, it may still have a significant impact on the normal operation of the equipment and signal transmission. Therefore, it is necessary to detect and verify the electrical interruption of the connector under the influence of pressure shock, but there is currently no such test device.

[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] like Figure 1 As shown, the first aspect of the present invention proposes a wet plug connector dynamic pressure impact composite dynamic test system, which mainly includes a water pressure environment simulation container 10, a connector structure, an impact generator 30, a driving component 40, an electrical instantaneous interruption instrument 60 and a power supply 70. The driving component 40 is used to drive the connector structure to complete the plug-in and unplug action, and drive the impact generator 30 to apply hammering dynamic pressure to the driving connector. The electrical instantaneous interruption instrument 60 monitors whether the connector structure has a momentary current interruption, and the power supply 70 provides power for the above-mentioned electrical appliances.

[0039] like Figure 1As shown, the water pressure environment simulation container 10 is a sealed container with a sealing cover, and a water medium simulating seawater can be added into the interior through the sealing cover. Before the test, it is pressurized to a target pressure, for example, to 140MPa, by a pressurizing device 50 to simulate a deep sea environment.

[0040] Furthermore, a fixed plate 11 and a movable plate 12 are provided in the water pressure environment simulation container 10 . The fixed plate 11 is relatively fixed to the water pressure environment simulation container 10 , and the movable plate 12 can move along a first direction relative to the fixed plate 11 .

[0041] like Figure 3 As shown, a plurality of guide rods 121 are provided on the movable plate 12, and one end of the guide rod 121 is connected to the guide hole of the fixed plate 11 to limit the moving direction of the movable plate 12 so that it remains in the first direction.

[0042] In this way, the movable plate 12 can move closer to or farther away from the fixed plate 11 along the first direction, providing a base for the moving parts to attach during the test process.

[0043] Furthermore, the connector structure includes a socket 21 and a plug 22 , the plugging and unplugging directions of the socket 21 and the plug 22 are along a first direction, the socket 21 is connected to the fixed plate 11 , and the plug 22 is connected to the movable plate 12 via a fixed rod 221 .

[0044] In this way, when the movable plate 12 moves, the plug 22 moves synchronously. By controlling the position of the movable plate 12, the position of the plug 22 can be controlled. When the movable plate 12 is close to the fixed plate 11, the plug 22 moves toward the direction of the socket 21 to complete the plugging process. When the movable plate 12 is away from the fixed plate 11, the plug 22 moves in the direction away from the socket 21 to complete the unplugging process.

[0045] The socket 21 and the plug 22 are connected to the instantaneous power failure meter 60 and the power supply 70 arranged outside the water pressure environment simulation container 10 through watertight cables.

[0046] Furthermore, the impact generator 30 is used to apply dynamic pressure to the connector structure by hammering, and the dynamic pressure applied by hammering simulates whether the connector will be momentarily disconnected when it is hit underwater or when it collides during insertion and removal.

[0047] In the above process, the driving component 40 is used to drive the movable plate 12 to reciprocate, so that the plug 22 and the socket 21 can be plugged in and out, and the impact generator 30 can be driven to complete the hammering action.

[0048] Among them, during the reciprocating motion of the movable plate 12, it should be understood that the plug 22 and the socket 21 include three processes of insertion-connection-unplugging, wherein the insertion process refers to the process in which the plug 22 and the socket 21 are close to each other but the connecting terminals are not in contact, the connection process refers to the process in which the connecting terminals in the plug 22 and the socket 21 are in contact with each other, during which the plug 22 and the socket 21 substantially complete the transmission of electrical signals, and the unplugging process refers to the hammering of the connector structure by the impact generator 30 during the connection process.

[0049] Since the connection terminals of the plug 22 and the socket 21 are not in contact during the insertion and removal process, the hammering process can only be applied during the connection process. Therefore, the timing of the hammering needs to be controlled.

[0050] Furthermore, the impact generator 30 is movably connected to the fixed plate 11, and the impact generator 30 is configured to be driven by the driving component 40 to perform reciprocating motion along the first direction, including an energy storage process and a hammering process, and the hammering process is in the connection process.

[0051] In this way, the impact generator 30 stores energy outside the connection process. When the connector is in the connection process, hammering occurs, and the vibration and impact force caused by the hammering simulate the impact, and test whether the connector has a momentary power failure under such impact.

[0052] Preferably, since the driving component 40 is in an underwater environment and the cost of a watertight motor is relatively high, the driving component 40 includes only one motor, specifically, Figure 2 As shown, the driving component 40 includes a motor 41, a cam plate 42, a first protruding structure 43 and a second protruding structure 44. The cam plate 42 is fixed to the output end of the motor 41, and the first protruding structure 43 and the second protruding structure 44 are fixed to the cam plate 42 and make circular motion around the axis of the cam plate 42.

[0053] Combination Figure 1 and Figure 2 As shown, the first protruding structure 43 and the second protruding structure 44 are respectively located on both sides of the cam plate 42, the first protruding structure 43 is used to drive the impact generator 30 to reciprocate along the first direction, and the second protruding structure 44 is used to drive the movable plate 12 to reciprocate along the first direction.

[0054] like Figure 3 and Figure 4 As shown, a connecting rod 13 is provided on the movable plate 12, and a waist-shaped sleeve 131 is provided at one end of the connecting rod 13 away from the movable plate 12. The second protruding structure 44 is in the waist-shaped sleeve 131, and the waist-shaped sleeve 131 is provided with a waist-shaped groove perpendicular to the first direction. The second protruding structure 44 slides in the waist-shaped groove. When the cam plate 42 rotates one circle, the connecting rod 13 moves back and forth once along the first direction.

[0055] In this way, when the second protruding structure 44 is at the leftmost end, the rotation angle range is large, and the displacement of the second protruding structure 44 in the first direction is small, which can reduce the influence of the plugging and unplugging process on the hammering effect.

[0056] Combination Figure 3 As shown, when the cam plate 42 rotates counterclockwise and the second protruding structure 44 is located in the upper part of the cam plate 42, the second protruding structure 44 slides in the upper part of the waist-shaped groove, driving the connecting rod 13 to move to the left, so that the plug 22 moves toward the direction close to the socket 21, and the insertion process can be completed. When the second protruding structure 44 is located at the left end of the cam plate 42, the plug 22 and the socket 21 are inserted the deepest and are in the connection process. When the second protruding structure 44 is around the leftmost end, the connecting terminals of the plug 22 and the socket 21 come into contact and are also in the connection process. When the second protruding structure 44 moves from the leftmost end to the right, it drives the connecting rod 13 to move to the right, so that the plug 22 is separated from the socket 21.

[0057] Furthermore, in order to prevent the impact force of the impact generator 30 on the plug 22 from being affected by the pulling-out action when the plug 22 continuously completes the plugging and unplugging process due to the continuous rotation of the cam plate 42, the waist-shaped sleeve 131 is designed to be an elastic material.

[0058] In this way, the plug 22 will maintain a relatively stable connection state during the plugging and unplugging process. During this process, when the impact generator 30 strikes, the socket 21 and the plug 22 are subjected to hammering vibrations, and the electrical connection state of the socket 21 and the plug 22 is only affected by the hammering but not by the plugging and unplugging process. Therefore, the test is relatively accurate.

[0059] like Figure 5 and Figure 6 As shown, the impact generator 30 includes a hammer head 31, a connecting rod 32, a contact plate 33 and a spring 34. The two ends of the connecting rod 32 are respectively connected to the hammer head 31 and the contact plate 33. The connecting rod 32 is slidably connected to the fixed plate 11. The spring 34 is arranged between the contact plate 33 and the fixed plate 11, so that the hammer head 31 is in contact with the fixed plate 11 in the reset position. During the rotation of the cam plate 42, the spring 34 includes a force storage and release process. During the force storage process, the first protruding structure 43 drives the contact plate 33 to compress the spring 34. During the release process, the first protruding structure 43 is out of contact with the contact plate 33.

[0060] Combination Figure 5As shown, when the cam plate 42 rotates counterclockwise, especially when the first protruding structure 43 is in the upper half, the contact plate 33 is squeezed to the left, the spring 34 is compressed and stored, and the hammer head 31 moves away from the fixed plate 11. When the first protruding structure 43 rotates to the leftmost end, the first protruding structure 43 and the contact plate 33 are disengaged, the spring 34 is released, and the hammer head 31 hammers the fixed plate 11 to complete the hammering process.

[0061] In other embodiments, the rotation state of the cam plate 42 can be controlled to avoid the hammering process being affected by the plugging and unplugging action of the plug 22. For example, when the first protruding structure 43 is just out of contact with the contact plate 33, the rotation of the cam plate 42 is stopped. During this process, the connection state of the socket 21 and the plug 22 is only affected by the hammering. After the hammering occurs, the cam plate 42 is controlled to continue rotating.

[0062] In an optional embodiment, the first protruding structure 43 and the second protruding structure 44 are arranged at different circumferential positions of the cam plate 42. For example, the first protruding structure 43 is slightly forward of the second protruding structure 44 in the circumferential direction. When the second protruding structure 44 moves to the leftmost end, the first protruding structure 43 and the contact plate 33 are out of contact.

[0063] Specifically, along the rotation direction of the cam plate 42, in the process of 0°~170°, the plug 22 and the socket 21 are in the insertion process, in the process of 170°~190°, the plug 22 and the socket 21 are in the connection process, and the impact generator 30 is in the switching process between the energy storage process and the hammering process, that is, the first protruding structure 43 and the contact plate 33 are out of contact, and in the process of 190°~360°, the plug 22 and the socket 21 are in the removal process.

[0064] Further, such as Figure 7 As shown, a connecting plate 14 is provided on the side of the fixing plate 11 facing the hammer head 31, a first inclined surface 311 is provided on the surface of the hammer head 31, and a second inclined surface 141 is provided on the connecting plate 14. When the hammer head 31 moves toward the connecting plate 14, the first inclined surface 311 and the second inclined surface 141 fit together, so that the connecting plate 14 has a force deviating from the first direction.

[0065] In this way, when the hammer head 31 collides with the second inclined surface 141 through the first inclined surface 311 , not only a force along the axial direction of the connector is generated, but also a force deviating from the axial direction can be generated to simulate a force of uncertain direction in a real collision.

[0066] Further, such as Figure 8As shown, the system also includes a pressure sensor 81, a camera 91 and a display 90. The camera 91 faces the plugging area of ​​the plug 22 and the socket 21 and is equipped with a fill light for monitoring the plugging process of the plug 22 and the socket 21, and the plugging picture is displayed on the display 90. The pressure sensor 81 is set in the hammer pressure area of ​​the impact generator 30, and is used to monitor the hammer pressure of the impact generator 30, and the hammer pressure is displayed on the display 90.

[0067] In this way, by visualizing the hammering pressure and the plugging action, it is helpful to observe the progress and process of the test in real time, thereby ensuring the authenticity and accuracy of the test.

[0068] The second aspect of the present invention proposes a technical solution, a wet plug connector dynamic pressure shock composite dynamic test method, using the above-mentioned wet plug connector dynamic pressure shock composite dynamic test system, comprising the following steps:

[0069] Step 1: Fill the water pressure environment simulation container 10 with water medium and pressurize it to a predetermined pressure through the pressurizing device 50;

[0070] Step 2, controlling the driving component 40 to make the movable plate 12 reciprocate along the first direction, completing the plugging and unplugging action of the plug 22 and the socket 21 and the hammering action of the impact generator 30;

[0071] Specifically, when the cam plate 42 rotates counterclockwise and the second protruding structure 44 is located in the upper part of the cam plate 42, the second protruding structure 44 slides in the upper part of the waist-shaped groove, driving the connecting rod 13 to move to the left, so that the plug 22 moves in the direction close to the socket 21, and the insertion process can be completed. When the second protruding structure 44 is located at the left end of the cam plate 42, the plug 22 and the socket 21 are inserted deepest and are in the connection process. When the second protruding structure 44 is around the leftmost end, the connecting terminals of the plug 22 and the socket 21 come into contact, and are also in the connection process. When the second protruding structure 44 moves from the leftmost end to the right, it drives the connecting rod 13 to move to the right, so that the plug 22 is separated from the socket 21.

[0072] Furthermore, when the cam plate 42 rotates counterclockwise, especially when the first protruding structure 43 is in the upper part, the contact plate 33 is squeezed to the left, the spring 34 is compressed and stored, and the hammer head 31 moves away from the fixed plate 11. When the first protruding structure 43 rotates to the leftmost end, the first protruding structure 43 and the contact plate 33 are disengaged, the spring 34 is released, and the hammer head 31 hammers the fixed plate 11 to complete the hammering process.

[0073] In a specific embodiment, along the rotation direction of the cam plate 42, in the process of 0°~170°, the plug 22 and the socket 21 are in the insertion process, in the process of 170°~190°, the plug 22 and the socket 21 are in the connection process, and the impact generator 30 is in the switching process between the energy storage process and the hammering process, that is, the first protruding structure 43 and the contact plate 33 are out of contact, and in the process of 190°~360°, the plug 22 and the socket 21 are in the removal process.

[0074] Step 3: Monitor the electrical connection status between the plug 22 and the socket 21 through the electrical transient interruption meter 60;

[0075] In step 2, the plug 22 and the socket 21 are controlled to complete a predetermined number of plugging and unplugging actions, and the electrical connection state of the plug 22 and the socket 21 during each hammering is recorded.

[0076] In an optional embodiment, the hammer force in the test is controlled by the spring 34, and one spring 34 can be tested multiple times. After the test is completed, the spring 34 with different stiffness is replaced for the next test to gradually complete the test of various impact forces.

[0077] In this way, through this test, it can be obtained whether this impact will cause a momentary power outage in the connector. If the impact causes a momentary power outage, the momentary power outage instrument 60 can detect the occurrence of the momentary power outage. Otherwise, no momentary power outage occurs during the impact process.

[0078] In combination with the above embodiments, the present application uses an underwater motor to realize the plugging / separation and impact actions of the wet plug-in connector under high water pressure; not only does it save equipment costs, but the entire device is mechanically driven, which can ensure accurate impact when the connector is plugged in; pressure sensors, underwater searchlights and cameras are installed in the water pressure equipment inside the equipment, and are led out to the outside of the water pressure equipment through watertight cables and watertight connectors, so as to realize the visualization and detectability of the test process; the impact kinetic energy is obtained by compressing the spring to store energy and releasing the spring to drive the impact hammer to move. The impact intensity can be adjusted by changing the spring stiffness, and various impact intensity tests can be performed.

[0079] 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.
