Description

Technical Field

[0001] The present application belongs to the technical field of underwater connector detection, and specifically relates to a waterproof and pressure resistance performance detection tool for underwater connectors. Background Art

[0002] Underwater connectors are connecting devices used to transmit signals, electricity or data in underwater environments. With the implementation of the national marine strategy, the use of underwater connectors is becoming more and more extensive. Since underwater connectors are used in underwater environments, and as the depth of their installation locations continues to increase, the water pressure they withstand becomes greater and greater. This leads to the waterproof performance and pressure resistance of underwater connectors becoming important evaluation criteria for evaluating whether underwater connectors are qualified. Therefore, underwater connectors need to be tested for their waterproof and pressure resistance before leaving the factory or before use.

[0003] In related technologies, such as Figure 1 As shown, the underwater connector 8 is usually installed on the end cover 71 of the pressure vessel 7, and then water is filled into the pressure vessel 7 and pressurized to place the underwater connector 8 under a set water pressure environment, so as to detect the waterproof and pressure performance of the underwater connector 8; however, in order to facilitate the connection of the underwater connector 8 to the end cover 71 of the pressure vessel 7, it is necessary to open a connection hole on the end cover 71 of the pressure vessel 7, and install the underwater connector 8 in the connection hole. Due to the different models of the underwater connector 8, connection holes with different apertures are required, so the end cover 71 of the pressure vessel 7 needs to be replaced or modified, which leads to This results in poor flexibility in the existing detection method and increases the detection cost of the underwater connector 8; at the same time, the number of connection holes that can be opened on the end cover 71 of the pressure vessel 7 is limited, resulting in a limited number of underwater connectors 8 that can be detected at a single time, thereby affecting the detection efficiency of the underwater connector 8; and when the detected underwater connector 8 is defective, its pressure resistance may be poor, which may cause the underwater connector 8 to disintegrate and splash out through the connection hole, thereby affecting the safety of the detection of the underwater connector 8; in addition, when the underwater connector 8 is detected, the effect of its waterproof performance is not obvious, resulting in a low detection accuracy. Summary of the invention

[0004] The present application provides a waterproof and pressure resistance testing tool for underwater connectors to reduce the testing cost of underwater connectors and improve the testing efficiency, safety and accuracy of underwater connectors.

[0005] The technical solution adopted in this application is: A waterproof and pressure resistance testing tool for an underwater connector comprises a shell and a first cover. One end of the shell is open, the shell is provided with a connecting hole connected to the inner space of the shell, the first cover is provided with a mounting hole for installing the underwater connector, and the first cover is detachably connected to the open end of the shell.

[0006] By adopting the above technical scheme, when using the waterproof and pressure resistance performance testing tool in the present application, the end of the underwater connector is installed in the installation hole, and then the waterproof and pressure resistance performance testing tool with the underwater connector installed is placed in the pressure vessel, and then the end cover of the pressure vessel is covered and water is injected into the pressure vessel and pressurized to make the pressure in the pressure vessel reach the set value. If the underwater connector does not disintegrate and does not leak after a period of time, it means that the underwater connector is a qualified product; if the underwater connector disintegrates or leaks after a period of time, it means that the underwater connector is a defective product. When the defective underwater connector is cracked, the wall of the pressure vessel can block the cracked underwater connector to avoid the possibility that the cracked fragments may cause harm to the staff, so as to increase the safety of the underwater connector during testing.

[0007] Furthermore, when using the waterproof and pressure resistance performance testing tooling in the present application to test the underwater connector, the external air supply equipment can also be connected to the connecting hole, and then the waterproof and pressure resistance performance testing tooling with the underwater connector installed can be immersed in water, and then the underwater connector can be observed to see whether bubbles are coming out, so as to further test the waterproof performance of the underwater connector, making it more intuitive to determine whether the underwater connector is leaking, avoiding false detection, and improving the accuracy of underwater connector detection, thereby improving the customer's experience.

[0008] In addition, since the underwater connector is usually installed on the outside of the chassis when in use, the connecting hole can be sealed before the waterproof and pressure resistance testing tooling equipped with the underwater connector is placed in the pressure vessel to simulate the actual use scenario of the underwater connector, thereby further improving the detection accuracy of the underwater connector to ensure the reliability of the underwater connector leaving the factory.

[0009] At the same time, when the waterproof and pressure resistance testing tooling in the present application is used to test underwater connectors, the need to open a connection hole on the end cover of the pressure vessel is eliminated, thereby enabling multiple underwater connectors to be placed in the pressure vessel at the same time, thereby improving the testing efficiency of the underwater connectors; and when testing underwater connectors of different models, only the first end cover needs to be replaced, thereby greatly reducing the testing cost of the underwater connectors.

[0010] Optionally, the communicating hole is provided on a side of the shell.

[0011] By adopting the above technical solution, since the connecting hole is located on the side of the shell, it is easy to connect the external air supply equipment with the connecting hole, thereby improving the connection efficiency between the external air supply equipment and the connecting hole, thereby improving the detection efficiency of the underwater connector.

[0012] Optionally, the shell has an opposite end opposite to its own open end, and the communicating hole is arranged at the opposite end.

[0013] By adopting the above technical solution, since the connecting hole is arranged at the opposite end, and the opposite end is the end of the shell opposite to its own opening, the connecting hole and the installation position of the underwater connector are arranged relative to each other, so that when the waterproof performance of the underwater connector is tested by supplying air to the shell, the flow of gas is smoother, so as to further improve the accuracy of the detection of the waterproof performance of the underwater connector.

[0014] Optionally, the shell includes a cylinder with both ends open and a second cover body detachably connected to the open end of the cylinder, the connecting hole is arranged in the second cover body, and the first cover body is detachably connected to the open end of the cylinder.

[0015] By adopting the above technical solution, since the shell includes a cylinder and a second cover body, the connecting hole is provided in the second cover body, and then before the waterproof and pressure resistance performance testing tooling equipped with the underwater connector is placed in the pressure vessel, the second cover body can be replaced with a cover body without a connecting hole, so as to truly simulate the use scenario of the underwater connector and further improve the detection accuracy of the underwater connector.

[0016] Optionally, a third cover body is further included, and the third cover body can replace the second cover body and be detachably connected to the open opening of the cylinder body or detachably connected to the connecting hole.

[0017] By adopting the above technical solution, before placing the waterproof and pressure resistance testing tool equipped with an underwater connector into a pressure vessel, the second cover body can be removed and the third cover body can be connected to the end of the cylinder to form a sealed space inside the cylinder, so as to truly simulate the use scenario of the underwater connector and thereby improve the detection accuracy of the underwater connector.

[0018] Before placing the waterproof and pressure resistance testing tool equipped with an underwater connector into the pressure vessel, the third cover body can be installed at the connecting hole, and then the third cover body can be used to seal the connecting hole to form a sealed space inside the cylinder to simulate the actual use scenario of the connector underwater, thereby improving the detection accuracy of the underwater connector.

[0019] Optionally, a sealing ring is provided between the first cover body and the shell, and after the first cover body is installed on the shell, the sealing ring is in a deformed state due to the mutual squeezing action of the first cover body and the shell.

[0020] By adopting the above technical solution, since a sealing ring is provided between the first cover body and the shell, and after the first cover body is installed on the shell, the sealing ring is in a deformed state under the mutual extrusion of the first cover body and the shell, and then the sealing ring can seal the gap between the first cover body and the cylinder body to increase the sealing between the two, thereby increasing the sealing of the internal space of the shell, so as to further simulate the actual use scenario of the underwater connector, and further improve the detection accuracy of the underwater connector.

[0021] Optionally, an annular groove is provided at the end of the shell, and at least a part of the sealing ring is located in the annular groove.

[0022] By adopting the above technical solution, since at least part of the sealing ring is located in the annular groove, the groove wall of the annular groove can limit the sealing ring to increase the stability of the sealing ring, and avoid the sealing ring from escaping from between the first cover body and the shell body due to the mutual squeezing action of the first cover body and the shell body. At the same time, it can also avoid the sealing ring from being easily moved when installing the first cover body, thereby reducing the difficulty of installing the first cover body.

[0023] Optionally, the first cover has a sealing portion extending into the shell, and an outer periphery of the sealing portion abuts against an inner wall of the shell.

[0024] By adopting the above technical solution, after the first cover body is installed on the shell, the sealing part extends into the interior of the shell, and the outer periphery of the sealing part contacts the interior of the shell, thereby increasing the connection area between the first cover body and the shell, and further increasing the sealing between the first cover body and the shell; in addition, when installing the first cover body, the sealing part can also play a guiding and positioning role for the first cover body, so as to further reduce the difficulty of installing the first cover body, further improve the installation efficiency of the first cover body, and indirectly improve the detection efficiency of the underwater connector.

[0025] Optionally, the first cover is detachably connected to the shell by bolts.

[0026] By adopting the above technical solution, since the first cover body is detachably connected to the shell by bolts, on the one hand, it is easy to connect the first cover body and the shell together, and on the other hand, the connection stability between the first cover body and the shell is increased, and it also avoids the need to make other designs on the first cover body or the cylinder body, so as to reduce the production cost of the waterproof and pressure resistance testing tooling.

[0027] Optionally, elastic arms extending away from the central axis of the shell are provided on opposite sides of the shell, a housing space for accommodating the shell is formed between the elastic arms, and an opening of the housing space is formed at one end of the elastic arm away from the shell.

[0028] By adopting the above technical solution, when testing multiple underwater connectors at the same time, multiple waterproof and pressure resistance performance testing tools equipped with underwater connectors can be connected together through elastic arms, that is, one of two adjacent waterproof and pressure resistance performance testing tools is located in the accommodating space of the other waterproof and pressure resistance performance testing tool, so as to achieve the effect of quickly placing multiple waterproof and pressure resistance performance testing tools into the pressure vessel, thereby further improving the testing efficiency of the underwater connector, and multiple waterproof and pressure resistance performance testing tools can be connected together through elastic arms, which can also increase the stability of the underwater connector in the pressure vessel.

[0040] Reference Figures 2 to 9 , discloses a waterproof and pressure resistance testing tool for an underwater connector, which includes a shell 1 and a first cover 2. One end of the shell 1 is open, and the shell 1 is provided with a connecting hole 121 connected to the internal space of the shell 1. The first cover 2 is provided with a mounting hole 21 for installing the underwater connector 8, and the first cover 2 is detachably connected to the open end of the shell 1.

[0041] When using the waterproof and pressure resistance testing tool in the present application, the end of the underwater connector 8 is installed in the installation hole 21, and then the waterproof and pressure resistance testing tool with the underwater connector 8 installed is placed in the pressure vessel 7, and then the end cover 71 of the pressure vessel 7 is covered and water is injected into the pressure vessel 7 and pressurized so that the pressure in the pressure vessel 7 reaches the set value. If the underwater connector 8 does not disintegrate and does not leak after a period of time, it means that the underwater connector 8 is a qualified product; if the underwater connector 8 disintegrates or leaks after a period of time or during the process of adding water and pressurizing, it means that the underwater connector 8 is a defective product. When the defective underwater connector 8 is cracked, the wall of the pressure vessel 7 can block the cracked underwater connector 8 to avoid the possibility that the cracked fragments may cause harm to the staff, so as to increase the safety of the underwater connector 8 when testing.

[0042] Furthermore, when using the waterproof and pressure resistance performance testing tooling in the present application to test the underwater connector 8, the external air supply equipment can also be connected to the connecting hole 121, and then the waterproof and pressure resistance performance testing tooling with the underwater connector 8 installed can be immersed in water, and then the underwater connector 8 is observed to see whether bubbles are coming out, so as to further test the waterproof performance of the underwater connector 8, so that it is more intuitive to determine whether the underwater connector 8 is leaking, and to avoid false detection, so as to improve the detection accuracy of the underwater connector 8 and thereby improve the customer's experience.

[0043] In addition, since the underwater connector 8 is usually installed on the outside of the chassis when in use, before the waterproof and pressure resistance testing tooling installed with the underwater connector 8 is placed in the pressure vessel 7, the connecting hole 121 can also be sealed to simulate the actual use scenario of the underwater connector 8, thereby further improving the detection accuracy of the underwater connector 8 to ensure the reliability of the underwater connector 8 leaving the factory.

[0044] At the same time, when the waterproof and pressure resistance testing tooling in the present application is used to test the underwater connector 8, the design of opening a connection hole on the end cover 71 of the pressure vessel 7 is eliminated, so that multiple underwater connectors 8 can be placed in the pressure vessel 7 at the same time, so as to improve the testing efficiency of the underwater connector 8; and when testing underwater connectors 8 of different models, it is only necessary to replace the first end cover 71, so as to greatly reduce the testing cost of the underwater connector 8.

[0045] When using the waterproof and pressure resistance performance testing tooling in the present application, the underwater connector 8 can be installed not only to the mounting hole 21, but also to the connecting hole 121. That is to say, two underwater connectors 8 can be installed on the same waterproof and pressure resistance performance testing tooling at the same time, wherein one underwater connector 8 is installed in the mounting hole 21, and the other underwater connector 8 is installed in the connecting hole 121, so as to further improve the detection efficiency of the underwater connector 8.

[0046] It is understandable that when connecting the external air supply device to the connecting hole 121 , an air pipe is required, that is, the connecting hole 121 is connected to the external air supply device through the air pipe.

[0047] The present application does not specifically limit the position of the communication hole 121, and it can adopt any one of the following embodiments: Embodiment 1. In this embodiment, referring to Figure 2 The connecting hole 121 is arranged on the side of the shell 1 to facilitate the connection between the external air supply equipment and the connecting hole 121, so as to improve the connection efficiency between the external air supply equipment and the connecting hole 121, thereby improving the detection efficiency of the underwater connector 8.

[0048] Implementation method 2. In this implementation method, refer to Figure 3 The shell 1 has an opposite end opposite to its own open end, and the connecting hole 121 is arranged at the opposite end, so that the connecting hole 121 is arranged relative to the installation position of the underwater connector 8, so that when the waterproof performance of the underwater connector 8 is tested by supplying air to the shell 1, the flow of gas is smoother, so as to further improve the detection accuracy of the waterproof performance of the underwater connector 8.

[0049] In this embodiment, the structure of the housing 1 is not specifically limited. Figure 3 The shell 1 includes a cylinder 11 with open ends and a second cover 12 detachably connected to the open end of the cylinder 11. The connecting hole 121 is provided on the second cover 12, and the first cover 2 is detachably connected to the open end of the cylinder 11. Before the waterproof and pressure resistance performance testing tool equipped with the underwater connector 8 is placed in the pressure vessel 7, the second cover 12 can be replaced with a cover without the connecting hole 121 to truly simulate the use scenario of the underwater connector 8 and further improve the detection accuracy of the underwater connector 8.

[0050] In some preferred implementation examples, refer to Figure 4 and Figure 5 The waterproof and pressure resistance performance testing tool also includes a third cover body 3, which can replace the second cover body 12 and be detachably connected to the open end of the cylinder body 11.

[0051] It can be understood that the third cover body 3 does not have the connecting hole 121, so that the third cover body 3 can replace the second cover body 12 to be connected to the end of the cylinder 11 and seal the cylinder 11, and the waterproof and pressure resistance performance testing tool in the present application has at least three covers, one of which is the first cover body 2 with the mounting hole 21, another is the second cover body 12 with the connecting hole 121, and the other is the third cover body 3 without a hole structure.

[0052] Before placing the waterproof and pressure resistance testing tool equipped with the underwater connector 8 into the pressure vessel 7, the second cover 12 can be removed and the third cover 3 can be connected to the end of the cylinder 11 to form a sealed space inside the cylinder 11, so as to truly simulate the usage scenario of the underwater connector 8 and thereby improve the detection accuracy of the underwater connector 8.

[0053] In some other preferred implementation examples, the waterproof and pressure resistance performance testing tool further includes a third cover body 3 , and the third cover body 3 is detachably connected to the connecting hole 121 .

[0054] That is, the third cover body 3 can be installed on the communicating hole 121 to seal the communicating hole 121 , that is, there is no need to replace the second cover body 12 .

[0055] Before placing the waterproof and pressure resistance testing tool equipped with the underwater connector 8 into the pressure vessel 7, the third cover body 3 can be installed at the connecting hole 121, and then the third cover body 3 can block the connecting hole 121 to form a sealed space inside the cylinder 11 to simulate the actual use scenario of the underwater connector, thereby improving the detection accuracy of the underwater connector 8.

[0056] In other embodiments, the housing 1 may also be an integral structure, that is, the second cover 12 and the cylinder 11 are an integral structure.

[0057] In a preferred embodiment, referring to Figure 5 A sealing ring 4 is arranged between the first cover body 2 and the shell 1. After the first cover body 2 is installed on the shell 1, the sealing ring 4 is in a deformed state under the mutual extrusion of the first cover body 2 and the shell 1, so that the sealing ring 4 can seal the gap between the first cover body 2 and the cylinder 11 to increase the sealing between the two, thereby increasing the sealing of the internal space of the shell 1, so as to further simulate the real use scenario of the underwater connector 8, and further improve the detection accuracy of the underwater connector 8.

[0058] Further, see Figure 5 and Figure 6A ring groove 111 is provided at the end of the shell 1, and at least a part of the sealing ring 4 is located in the ring groove 111, so that the groove wall of the ring groove 111 can limit the sealing ring 4 to increase the stability of the sealing ring 4, and prevent the sealing ring 4 from being separated from between the first cover body 2 and the shell 1 under the mutual squeezing effect. At the same time, it can also prevent the sealing ring 4 from being easily moved when the first cover body 2 is installed, so as to reduce the difficulty of installing the first cover body 2.

[0059] Preferably, in the above embodiment with the second cover 12, a sealing ring 4 is also provided between the second cover 12 and the cylinder 11, and annular grooves 111 are provided at both ends of the cylinder 11 to accommodate the sealing rings 4 at both ends thereof.

[0060] In a preferred embodiment, referring to Figure 2 and Figure 7 The first cover body 2 has a sealing portion 22 extending into the housing 1 , and the outer periphery of the sealing portion 22 abuts against the inner wall of the housing 1 .

[0061] Specifically, after the first cover body 2 is installed on the shell 1, the sealing portion 22 extends into the interior of the shell 1, and the outer periphery of the sealing portion 22 contacts the interior of the shell 1, thereby increasing the connection area between the first cover body 2 and the shell 1, and further increasing the sealing between the first cover body 2 and the shell 1; in addition, when installing the first cover body 2, the sealing portion 22 can also play a guiding and positioning role for the first cover body 2, so as to further reduce the difficulty of installing the first cover body 2, further improve the installation efficiency of the first cover body 2, and thereby indirectly improve the detection efficiency of the underwater connector 8.

[0062] The present application does not specifically limit the structure of the sealing portion 22. Preferably, refer to Figure 2 and Figure 7 The sealing portion 22 is a block structure provided on the first cover body 2, which can increase the axial dimension of the mounting hole 21 to increase the connection stability between the underwater connector 8 and the first cover body 2. In other embodiments, the sealing portion 22 can also be an annular structure.

[0063] Preferably, in the above embodiment having the second cover body 12 and the third cover body 3 , the second cover body 12 and the third cover body 3 also have a sealing portion 22 .

[0064] The present application does not specifically limit the detachable connection method between the first cover body 2 and the housing 1. Preferably, refer to Figure 1 and Figure 5The first cover body 2 is detachably connected to the shell body 1 by bolts 5, that is, the first cover body 2 is provided with a hole structure for the screw rod of the bolt 5 to pass through, and the end of the shell body 1 is provided with a threaded hole for the screw rod of the bolt 5 to be threadedly connected. The first cover body 2 is fixed by the screw rod of the bolt 5 passing through the first cover body 2 and being threadedly connected to the shell body 1. On the one hand, it is convenient to connect the first cover body 2 and the shell body 1 together, and on the other hand, it increases the connection stability of the first cover body 2 and the shell body 1, and also avoids the need to make other designs on the first cover body 2 or the cylinder body 11, so as to reduce the production cost of the waterproof and pressure resistance performance testing tooling.

[0065] Preferably, in the above-mentioned embodiment with the second cover body 12 and the third cover body 3 , the second cover body 12 and the third cover body 3 are also detachably connected to the cylinder body 11 by bolts 5 .

[0066] In other embodiments, the first cover 2 may also be detachably connected to the housing 1 via a snap-fit ​​structure.

[0067] In a preferred embodiment, referring to Fig. 9 Elastic arms 6 extending away from the central axis of the shell 1 are provided on opposite sides of the shell 1, and an accommodating space for accommodating the shell 1 is formed between the elastic arms 6, and an opening of the accommodating space is formed at one end of the elastic arm 6 away from the shell 1.

[0068] It can be understood that at least two elastic arms 6 are provided and are respectively located on two opposite sides of the housing 1 , and the two elastic arms 6 extend in the same direction so that an accommodating space can be formed between the two elastic arms 6 .

[0069] When testing multiple underwater connectors 8 at the same time, multiple waterproof and pressure resistance testing tools equipped with underwater connectors 8 can be connected together through elastic arms 6, that is, one of two adjacent waterproof and pressure resistance testing tools is located in the accommodating space of another waterproof and pressure resistance testing tool, so as to achieve the effect of quickly placing multiple waterproof and pressure resistance testing tools into the pressure vessel 7, thereby further improving the detection efficiency of the underwater connector 8, and can also increase the stability of the underwater connector 8 in the pressure vessel 7.

[0070] Specifically, when connecting two waterproof and pressure resistance testing tools together, align one of the waterproof and pressure resistance testing tools with the opening of the accommodating space on the other waterproof and pressure resistance testing tool, and then press both of them to deform the elastic arm 6, and gradually increase the opening of the accommodating space, so that the shell 1 of the other waterproof and pressure resistance testing tool moves into the accommodating space. After the shell 1 enters the accommodating space, the elastic arm 6 resumes its deformation to connect the two waterproof and pressure resistance testing tools together.

[0071] Further, see Fig. 9 The elastic arm 6 includes an elastic section 61 and a blocking section 62. One end of the elastic section 61 is fixedly connected to the shell 1, and the blocking section 62 is fixedly connected to the inner side of the elastic section 61 away from the end of the shell 1. There is a gap between the blocking sections 62 on the two elastic arms 6 to form an opening of the accommodating space, so that the blocking section 62 can block and limit the shell 1 located in the accommodating space, so as to increase the connection stability of two adjacent waterproof and pressure resistance testing tools.
