Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an underwater connector. Background Art

[0002] A connector is a device that connects two active devices. It is an electronic component that transmits and exchanges current or optical signals between electronic system devices. It is a basic component necessary for the connection of the entire system. There are many types of connectors, among which some special connectors need to be used underwater to connect underwater equipment, control underwater equipment from land, and transmit detection data of underwater detection equipment to land. They are called underwater connectors. Since connectors generally transmit current and electrical signals, and water is a taboo for electricity, it will not only cause a short circuit in the circuit, but also corrode the circuit. Therefore, for the design of underwater connectors, its waterproof sealing is the main function. In deeper water, the water pressure is relatively high, which is also a considerable test for the sealing of underwater connectors.

[0021] 1. During the plug-in process of the connector, the pump block slides, pumping the gas in the auxiliary cylinder into the annular groove, thereby causing the piston ring to slide. The sliding of the piston ring will pump the gas in the annular groove into the cavity, thereby causing the slider to slide. When the seal between the main cylinder and the auxiliary cylinder is good, all the gas is pumped into the annular groove, and at this time, the first conductive block will contact the second conductive block, thereby lighting the indicator ring. During the plug-in process, the sealing is monitored to avoid leakage that affects subsequent use;

[0023] 3. After the plugging and clamping are completed, the female plug will be energized. At the same time, the solenoid valve will be energized. At this time, the slider will pump the gas in the cavity into the liquid cavity under the action of water pressure, and push the slide column to move through the clamping block to complete the plugging of the female plug and the male plug in the power connection cavity. That is, the circuit will be turned on only when the sealing is good, avoiding direct circuit conduction in the case of poor sealing, causing unnecessary losses and damage;

[0024] 4. Before insertion, the pinhole is blocked by a blocking plate to prevent water from entering the power connection cavity from the pinhole. Before and after insertion, the sealing of the power connection cavity is guaranteed, effectively preventing water from entering the power connection cavity, and further ensuring the safety of the connection;

[0025] 5. When the slider pumps the gas into the liquid cavity, the pressure ring will slide. The sliding of the pressure ring will pump out the plugging agent in the liquid cavity and pump it into the gap between the pump block and the main cylinder. After applying a certain pressure to the gap, it will be further blocked to further improve the sealing of the connector;

[0026] 6. The water pressure is applied to the slider, causing it to slide back and seal. This allows the connector to automatically adjust the sealing pressure according to the depth of the water. The deeper the water, the greater the pressure applied to seal, further improving the sealing of the connector.

[0027] 7. During the operation of the connector, the internal sealing should be monitored at all times. When leakage occurs inside, external pressure will be applied to the inside, causing the piston ring to slide further. At this time, the clamping block will pass over the first conductive block, so that the two second conductive blocks are directly connected, disconnecting the connector circuit to ensure safety. At the same time, the alarm will sound, prompting the staff to carry out timely maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A monitoring mechanism is arranged in the main cylinder 101, the main base 1, and the auxiliary cylinder 201. The monitoring mechanism is composed of a sealed monitoring component and an energizing component.

[0040] The main base 1 and the auxiliary cylinder 201 are provided with a clamping mechanism, which includes a plurality of triggering grooves 123. The triggering grooves 123 are provided on the side wall of the main base 1 (such as Figure 4 As shown), the inner wall of the trigger slot 123 is fixedly connected with a switch 127. When the switch 127 is pressed, the power supply can be powered on. The switch 127 is a waterproof switch and is suitable for underwater use;

[0041] A rear plugging mechanism is provided in the main cylinder 101, and the rear plugging mechanism includes a plurality of second tubes 118, and the second tubes 118 are fixedly connected to the main base 1 and the main cylinder 101 through and through, and a solenoid valve 122 is provided in the second tube 118, and the solenoid valve 122 is a normally closed solenoid valve, which is opened when powered on;

[0042] A front blocking mechanism is arranged in the main cylinder 101 .

[0043] The sealing monitoring assembly includes an annular groove 102, which is provided in the main cylinder 101. The main cylinder 101 is sealed and slidably connected with a piston ring 103 through the annular groove 102. The main cylinder 101 and the main base 1 are penetrated and fixedly connected with a plurality of first tubes 105, which connect the cavity 104 with the annular groove 102. The auxiliary cylinder 201 is sealed and slidably connected with a pump block 203 (such as Figure 8 As shown), the pump block 203 is penetrated and fixedly connected with a plurality of fourth tubes 204, the male plug 205 pin is penetrated and slidably connected with the pump block 203, and a sealing rubber ring is provided at the penetration point for sealing.

[0044] The power supply assembly further includes a groove 107, which is provided in the slider 106. The inner side wall of the groove 107 is provided with two mounting grooves 112 (such as Figure 6 As shown, the slider 106 slides through the mounting groove 112 and has two clamping blocks 113. The side walls of the two clamping blocks 113 on the opposite sides are fixedly embedded with second conductive blocks 115. A plurality of first springs 114 are fixedly connected between the clamping blocks 113 and the inner wall of the mounting groove 112. The main cylinder 101 is provided with an electrical connection cavity 108. The main cylinder 101 is penetrated and slidably connected with a sliding column 109. One end of the sliding column 109 extends through the groove 107 and is fixedly embedded with two first conductive blocks 111. The other end is penetrated and connected with a sliding column 109. The main base 1 extends into the power connection cavity 108 and is fixedly connected with a female plug 110. The side wall of the main base 1 is fixedly connected with an indicator light ring 116. The second conductive block 115 and the alarm 3 are electrically connected through a wire. The indicator light ring 116, the female plug 110, the solenoid valve 122, and the first conductive block 111 are electrically connected through a wire. The main base 1 is provided with a plurality of connecting holes 117. The connecting holes 117 connect the cavity 104 with the outside world. Water can enter the cavity 104 through the connecting holes 117. The circuit connection relationship is as follows: Fig. 9As shown, when the first conductive block 111 contacts the corresponding second conductive block 115, the female plug 110, the solenoid valve 122 and the indicator light ring 116 are energized at the same time, and the auxiliary cylinder 201 inserts the main cylinder 101 into the interior thereof. During the process, the main cylinder 101 pushes the pump block 203 to slide. During the sliding process of the pump block 203, the space between the pump block 203 and the auxiliary cylinder 201 is reduced, so that the gas in the auxiliary cylinder 201 is pumped out through the fourth tube 204 and pumped into the annular groove 102. After the gas is pumped into the annular groove 102, the piston ring 103 is caused to slide. The sliding of the piston ring 103 pumps the gas in the annular groove 102 into the cavity 104 through the first tube 105, so that the slider 106 slides. After the insertion is completed, if the seal between the main cylinder 101 and the auxiliary cylinder 201 is good, the gas is all pumped into the annular groove 102, so that the piston ring 103 can pump a sufficient amount of gas into the cavity 104. The first spring 114 is used to slide the second conductive block 115 in the cavity 104, so that the sliding of the slider 106 is sufficient to make the clamping block 113 pass over the sliding column 109, so that the clamping block 113 slides relatively under the elastic force of the first spring 114, so that the second conductive block 115 contacts the first conductive block 111. After the power is turned on, if the seal between the main cylinder 101 and the auxiliary cylinder 201 is good, the second conductive block 115 contacts the first conductive block 111, and the indicator light ring 116 is powered on and lights up. If there is a leakage, part of the gas will be discharged through the leakage instead of all entering the annular groove 102. At this time, the sliding of the slider 106 is not sufficient to make the clamping block 113 pass over the sliding column 109. At this time, the second conductive block 115 does not contact the first conductive block 111, and the indicator light ring 116 does not light up. During the insertion process, the sealing is tested. By observing the state of the indicator light ring 116, it is possible to quickly judge whether the sealing is good, thereby avoiding the influence of leakage on subsequent use.

[0045] During use, if leakage occurs, the external water pressure will leak into the annular groove 102. Due to the relationship between the cross-sectional areas of the piston ring 103 and the slider 106, the water pressure will cause the piston ring 103 to drive the slider 106 to slide, thereby causing the clamping block 113 to slide. As the clamping block 113 slides, it will drive the second conductive block 115 to pass over the first conductive block 111, so that the two second conductive blocks 115 move and contact each other, short-circuiting the alarm 3, thereby causing the alarm 3 to sound an alarm. A sealing test is performed during insertion. During use, the sealing monitoring will continue to be ensured to effectively ensure the safety of the line.

[0046] The clamping mechanism also includes multiple fixed shafts 124, which are fixedly connected in the corresponding trigger grooves 123. The fixed shafts 124 are rotatably connected with hooks 125 through bearings. A second spring 126 is fixedly connected between the hooks 125 and the inner wall of the trigger groove 123. The sub-cylinder 201 is provided with a clamping groove 202, and the side wall of the hook 125 away from the main base 1 is an inclined surface, so as to ensure that the hook 125 can be lifted up during the sliding process of the sub-cylinder 201.

[0047] The rear plugging mechanism also includes a liquid cavity 119, which is opened in the main cylinder 101. The second tube 118 connects the cavity 104 with the liquid cavity 119. A pressure ring 121 is sealed and slidably connected in the liquid cavity 119. A plugging agent is filled between the pressure ring 121 and the side wall of the liquid cavity 119 away from the second tube 118. After the plugging agent is pumped out, the gap can be filled, thereby achieving a sealing effect. A plurality of third tubes 120 are fixedly connected through the main cylinder 101. The third tube 120 connects the liquid cavity 119 with the outside world. After the plugging is completed in a good sealing condition, When the female plug 110 and the indicator light ring 116 are energized, the solenoid valve 122 will also be energized and opened. At this time, under the action of water pressure, the slider 106 will pump the gas pumped into the cavity 104 into the liquid cavity 119 through the second tube 118, so that the pressure ring 121 slides, and the pressure ring 121 will pump the plugging agent out through the third tube 120, pump it into the gap between the pump block 203 and the main cylinder 101, and use the water pressure to pump the plugging agent out at a certain pressure to plug the leak. After the insertion is completed, the sealing is strengthened by pumping out the plugging agent to further avoid leakage.

[0048] It is worth mentioning that the plugging agent is pumped out by water pressure, so that the plugging agent is pumped out with a certain pressure, and the pressure is provided by the water pressure, so that the connector can automatically adjust the sealing pressure according to the underwater depth. The deeper the water is, the greater the pressure is applied to seal, which further improves the sealing of the connector.

[0049] The front blocking mechanism includes a plate slot 128 (such as Figure 7As shown in the figure, the plate groove 128 is provided in the main cylinder 101, and the main cylinder 101 is slidably connected with a blocking plate 130 through the plate groove 128. A third spring 132 is fixedly connected between the blocking plate 130 and the inner wall of the plate groove 128. The main cylinder 101 is provided with a plurality of pinholes 129, and the pinholes 129 connect the power receiving chamber 108 with the outside. The pinholes 129 penetrate the plate groove 128, and the blocking plate 130 is provided with a plurality of overlap holes 131, and the overlap holes 131 correspond to the pinholes 129 one by one. When the blocking plate 130 slides up, the overlap holes 131 will overlap with the pinholes 129, so that the pinholes 129 can be The hole 129 is open. During the insertion process, the sliding of the piston ring 103 will also release the limit on the blocking plate 130, so that the blocking plate 130 slides up under the elastic force of the third spring 132. After sliding up, the overlapping hole 131 and the pinhole 129 will be opened one by one. At this time, with the insertion of the secondary cylinder 201, the pin of the male plug 205 will be inserted into the power connection chamber 108 through the overlapping hole 131 and the pinhole 129. When not inserted, the power connection chamber 108 is sealed by the blocking plate 130 to prevent water from entering the power connection chamber 108. When inserted, the power connection chamber 108 will be automatically opened.

[0050] The slide post 109 and the clamping block 113 are both made of polytetrafluoroethylene material. Polytetrafluoroethylene material has higher strength and insulation properties, avoiding unnecessary circuit conduction. It also has stronger corrosion resistance and is more suitable for underwater use.

[0051] A one-way valve is arranged in the fourth tube 204. The one-way valve in the fourth tube 204 only allows gas to enter the annular groove 102 from the sub-cylinder 201. The cross-sectional area of ​​the piston ring 103 is smaller than the cross-sectional area of ​​the slider 106. By setting the size of the cross-sectional area, on the one hand, when pressure is applied to the piston ring 103, the slider 106 can be driven to move with a greater force, thereby more easily resisting the water pressure. On the other hand, after leakage occurs, when the same force is applied on both sides of the piston ring 103 and the slider 106, the pressure of the piston ring 103 on the slider 106 can be made greater, so that when leakage occurs, the piston ring 103 will drive the slider 106 to slide. A plurality of guide strips 133 are fixedly connected to the inner side wall of the annular groove 102. The guide strips 133 are sealed and penetrate the piston ring 103 for sliding connection. The setting of the guide strips 133 allows the piston ring 103 to slide more stably.

[0052] A one-way valve is disposed in the third tube 120 , and the one-way valve in the third tube 120 only allows the plugging agent to be discharged from the liquid chamber 119 to the outside.

[0053] The auxiliary cylinder 201 and the annular groove 102 are filled with nitrogen. The filling of nitrogen ensures that the piston ring 103 and the slider 106 can be driven to move better by the gas.

[0054] In the present invention, after the main base 1 is installed at the desired position, the circuits are connected, and then the auxiliary cylinder 201 and the main cylinder 101 are plugged into each other.

[0055] During the insertion process, the secondary cylinder 201 inserts the main cylinder 101 into the inside thereof. During the process, the main cylinder 101 pushes the pump block 203 to slide. During the sliding process of the pump block 203, the space between the pump block 203 and the secondary cylinder 201 is reduced, so that the gas in the secondary cylinder 201 is pumped out through the fourth tube 204 and pumped into the annular groove 102. After the gas is pumped into the annular groove 102, the piston ring 103 will slide. The sliding of the piston ring 103 will pump the gas in the annular groove 102 into the piston ring 103 through the first tube 105. The sliding block 106 slides in the cavity 104. After the insertion is completed, if the seal between the main cylinder 101 and the auxiliary cylinder 201 is good, the gas is all pumped into the annular groove 102, so that the piston ring 103 can pump a sufficient amount of gas into the cavity 104, so that the sliding of the sliding block 106 is sufficient to make the clamping block 113 pass over the sliding column 109, so that the clamping block 113 slides relatively under the elastic force of the first spring 114, so that the second conductive block 115 contacts the first conductive block 111.

[0056] At the same time, the insertion of the secondary cylinder 201 will lift the hook 125 until the hook 125 moves relatively to the slot 202. At this time, under the elastic force of the second spring 126, the hook 125 rotates and is inserted into the slot 202. At the same time, the hook 125 presses the switch 127, thereby turning on the power of the connector.

[0057] After the power is turned on, if the seal between the main cylinder 101 and the auxiliary cylinder 201 is good, the second conductive block 115 contacts the first conductive block 111, and the indicator light ring 116 is powered on and lights up. If there is a leakage, part of the gas will be discharged through the leakage instead of entering the annular groove 102. At this time, the sliding of the slider 106 is not enough to make the clamping block 113 pass over the sliding column 109. At this time, the second conductive block 115 will not contact the first conductive block 111, and the indicator light ring 116 will not light up.

[0058] During the insertion process, the sliding of the piston ring 103 will also release the limit on the blocking plate 130, allowing the blocking plate 130 to slide up under the elastic force of the third spring 132. After sliding up, the overlapping holes 131 and the pinholes 129 will be opened one by one. At this time, with the insertion of the secondary cylinder 201, the pins of the male plug 205 will be inserted into the power connection cavity 108 through the overlapping holes 131 and the pinholes 129.

[0059] After the plugging is completed under the condition of good sealing, the female plug 110 and the indicator light ring 116 are energized, and the solenoid valve 122 is also energized and opened. At this time, under the action of water pressure, the slider 106 pumps the gas in the cavity 104 into the liquid cavity 119 through the second tube 118, so that the pressure ring 121 slides, and the pressure ring 121 pumps the plugging agent out through the third tube 120, pumped into the gap between the pump block 203 and the main cylinder 101, and the plugging agent is pumped out at a certain pressure through the water pressure to plug the leak.

[0060] When the slider 106 slides back under the action of water pressure, it will push the slide post 109 through the clamping block 113, so that the slide post 109 slides, driving the female plug 110 to slide, so that the female plug 110 and the male plug 205 are plugged in and energized in the power connection cavity 108.

[0061] During the use of the connector, if a leakage occurs, the external water pressure will leak into the annular groove 102. Due to the relationship between the cross-sectional areas of the piston ring 103 and the slider 106, the water pressure will cause the piston ring 103 to drive the slider 106 to slide, thereby causing the clamping block 113 to slide. As the clamping block 113 slides, it will drive the second conductive block 115 to pass over the first conductive block 111, so that the two second conductive blocks 115 move and contact each other, short-circuiting the alarm 3, causing the alarm 3 to sound an alarm, and notifying the staff to carry out timely maintenance and replacement.
