Description

Technical Field

[0001] This invention relates to the field of underwater equipment testing devices, specifically to a remote rapid disengagement device for underwater submersibles and its usage method. Background Technology

[0002] In the operation of underwater vehicles, detectors and other equipment at sea, the routine operating procedure usually includes: transporting the equipment to the designated work point by a surface vessel, then using a crane on board to lower the equipment to the target water depth, and then disconnecting the lifting cable from the underwater equipment.

[0003] In the existing technology, the currently used rapid separation devices are of two types: one is connected by pure electromagnetic adsorption, and the two parts are adsorbed when energized and separated when energized; the other is locked by a mechanical mechanism, and the parts are quickly separated by their own weight after unlocking.

[0004] However, rapid detachment devices based on pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using such devices will come to a standstill. Rapid detachment devices based on mechanical locking mechanisms are generally more complex in structure and may fail in harsh environments, both of which present the problem of difficulty in achieving stable rapid detachment. Summary of the Invention

[0005] This application provides a remote rapid detachment device and method for use for underwater vehicles, which can solve the problem that existing rapid detachment devices based on pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using the rapid detachment device based on pure electromagnetic adsorption will come to a standstill. Rapid detachment devices based on mechanical locking mechanisms are generally more complex in structure and may fail in harsh environments. Both of these have the problem of difficulty in achieving stable rapid detachment.

[0006] In a first aspect, embodiments of this application provide a remotely rapid disengagement device for an underwater vehicle, comprising:

[0007] An upper connector for connecting to a cable is provided with a mounting hole on its outer side and a connecting cavity at one end of the upper connector, the connecting cavity communicating with the mounting hole;

[0008] A lower connector is used to connect to underwater equipment. One end of the lower connector is used to extend into the connecting cavity. The portion of the lower connector that extends into the connecting cavity is provided with a groove corresponding to the mounting hole.

[0009] A preload assembly is disposed within the mounting hole. The preload assembly includes an abutment ball and a retaining spring. The abutment ball is used to abut within the groove, and the retaining spring is used to abut against the abutment ball.

[0010] A drive assembly, disposed on the upper connector, is used to drive the abutment spring to move in order to adjust the abutment force on the abutment ball.

[0011] In one embodiment, the preload assembly further includes a sealing plug detachably disposed at the outer end of the mounting hole and adjustable in length into the mounting hole, wherein one end of the sealing plug extending into the mounting hole is connected to the end of the abutment spring away from the abutment ball.

[0012] In one embodiment, the driving component is an electromagnetic coil sleeved on the outside of the upper connector. The driving component is located at the mounting hole and is used to adjust the position of one end of the abutting spring against the abutting ball, so as to adjust the abutting force of the abutting spring against the abutting ball.

[0013] In one embodiment, the preload assembly further includes a metal top plate with a cross-sectional area greater than the maximum cross-sectional area of ​​the abutment ball. The metal top plate is disposed at the end of the abutment spring and is used to abut against the abutment ball.

[0014] In one embodiment, four mounting holes are provided circumferentially spaced on the outer side of the upper connector, and the axis of the mounting holes is arranged along the radial direction of the upper connector.

[0015] In one embodiment, the portion of the lower connector extending into the connecting cavity matches the shape of the connecting cavity, and the portion of the lower connector extending into the connecting cavity is divided into a large-diameter section and a small-diameter section, the large-diameter section being located at the opening of the connecting cavity, and the small-diameter section being provided with the groove.

[0016] In one embodiment, a sealing ring mounting groove is provided on the large-diameter section, and the sealing ring mounting groove is used to install a first sealing ring.

[0017] Secondly, this application also provides a method for using a remote rapid disengagement device for an underwater vehicle, which is implemented using the aforementioned remote rapid disengagement device for an underwater vehicle, and includes the following steps:

[0018] If a disengagement operation is performed and the drive assembly is in normal operating condition, the drive retaining spring moves, adjusting the retaining force on the abutment ball. The abutment ball is squeezed into the mounting hole by the groove, causing the upper connector and the lower connector to separate.

[0019] If a disengagement operation is performed and the drive assembly is in a stopped operating state, the upper connector is raised at a set speed, generating a corresponding tension between the upper and lower connectors. Under the action of the tension, the abutment ball is squeezed into the mounting hole by the groove, causing the upper and lower connectors to separate.

[0020] In one implementation, prior to the disengagement operation, the method further includes:

[0021] The preload of the supporting spring is obtained based on the weight of the underwater equipment;

[0022] The physical parameters of the supporting spring are determined based on the preload of the supporting spring.

[0023] In one embodiment, determining the physical parameters of the supporting spring based on its preload includes:

[0024] The compression amount is preset when the supporting spring provides preload;

[0025] The stiffness of the retaining spring is determined based on the preload of the retaining spring and the amount of compression of the retaining spring in the preloaded state.

[0026] The beneficial effects of the technical solutions provided in this application include:

[0027] When using the underwater vehicle remote rapid disengagement device, the upper connector is used to connect to the cable. The outer side of the upper connector has a mounting hole, and one end of the upper connector has a connecting cavity that communicates with the mounting hole. The lower connector is used to connect to underwater equipment. One end of the lower connector is used to extend into the connecting cavity. The part of the lower connector that extends into the connecting cavity has a groove corresponding to the mounting hole. The pre-tightening component is set in the mounting hole. The pre-tightening component includes an abutment ball and a retaining spring. The abutment ball is used to abut in the groove, and the retaining spring is used to abut on the abutment ball. The drive component is set on the upper connector and is used to drive the retaining spring to move to adjust the retaining force on the abutment ball. If a disengagement operation is performed and the drive assembly is in normal operating condition, the drive retaining spring moves, adjusting the retaining force on the abutment ball. The abutment ball is compressed by the groove and retracts into the mounting hole, separating the upper and lower connectors. If a disengagement operation is performed and the drive assembly is in a stopped operating condition, the upper connector is raised at a set speed, generating a corresponding tension between the upper and lower connectors. Under the action of the tension, the abutment ball is compressed by the groove and retracts into the mounting hole, separating the upper and lower connectors. Since the disengagement operation can be completed in both normal and stopped operating conditions, the stability is good. This solves the problem that existing rapid disengagement devices using pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using a rapid disengagement device using pure electromagnetic adsorption will come to a standstill. Rapid disengagement devices using mechanical locking mechanisms are generally more complex in structure and may fail in harsh environments, both of which have the problem of difficulty in achieving stable rapid disengagement.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0039] This application provides a remote rapid disengagement device and method for underwater vehicles, which solves the problem that existing rapid disengagement devices based on pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using the rapid disengagement device based on pure electromagnetic adsorption will come to a standstill. Rapid disengagement devices based on mechanical locking mechanisms are generally more complex in structure and may fail in harsh environments. Both of these methods have the problem of making it difficult to achieve stable rapid disengagement.

[0040] like Figures 1-8 As shown, this application provides a remotely controlled rapid disengagement device for underwater vehicles, comprising:

[0041] The upper connector 1 is used to connect to the cable. The outer side of the upper connector 1 is provided with a mounting hole 11, and one end of the upper connector 1 is provided with a connecting cavity 12, which communicates with the mounting hole 11.

[0042] The lower connector 2 is used to connect to underwater equipment. One end of the lower connector 2 is used to extend into the connection cavity 12. The part of the lower connector 2 that extends into the connection cavity 12 is provided with a groove 21 corresponding to the mounting hole 11.

[0043] The pre-tightening component 3 is disposed in the mounting hole 11. The pre-tightening component 3 includes an abutting ball 31 and a retaining spring 32. The abutting ball 31 is used to abut in the groove 21, and the retaining spring 32 is used to abut on the abutting ball 31.

[0044] The drive assembly 4, which is disposed on the upper connector 1, is used to drive the abutment spring 32 to move in order to adjust the abutment force on the abutment ball 31.

[0045] When using the underwater vehicle remote rapid disengagement device, the upper connector 1 is used to connect to the cable. The outer side of the upper connector 1 is provided with a mounting hole 11, and one end of the upper connector 1 is provided with a connecting cavity 12, which communicates with the mounting hole 11. The lower connector 2 is used to connect to the underwater equipment. One end of the lower connector 2 is used to extend into the connecting cavity 12. The part of the lower connector 2 that extends into the connecting cavity 12 is provided with a groove 21 corresponding to the mounting hole 11. The pre-tightening component 3 is disposed in the mounting hole 11. The pre-tightening component 3 includes an abutment ball 31 and a retaining spring 32. The abutment ball 31 is used to abut in the groove 21, and the retaining spring 32 is used to abut on the abutment ball 31. The drive component 4 is disposed on the upper connector 1 and is used to drive the retaining spring 32 to move to adjust the retaining force on the abutment ball 31. If a disengagement operation is performed and the drive assembly 4 is in normal operating condition, the drive retaining spring 32 moves, adjusting the retaining force on the abutment ball 31. The abutment ball 31 is compressed by the groove 21 and retracts into the mounting hole 11, separating the upper connector 1 and the lower connector 2. If a disengagement operation is performed and the drive assembly 4 is in a stopped operating condition, the upper connector 1 is raised at a set speed, generating a corresponding tension between the upper connector 1 and the lower connector 2. Under the action of the tension, the abutment ball 31 is compressed by the groove 21 and retracts into the mounting hole 11, separating the upper connector 1 and the lower connector 2. Since the drive assembly 4 can complete the disengagement operation in both normal and stopped operating conditions, it has good stability. This solves the problem that existing rapid disengagement devices using pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using the rapid disengagement device using pure electromagnetic adsorption will come to a standstill. Rapid disengagement devices using mechanical locking mechanisms generally have a more complex structure and may fail in harsh environments, both of which have the problem of difficulty in achieving stable rapid disengagement.

[0046] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some optional embodiments, the pre-tightening assembly 3 further includes a sealing plug 33, which is detachably disposed at the outer end of the mounting hole 11 and has an adjustable length extending into the mounting hole 11. One end of the sealing plug 33 extending into the mounting hole 11 is connected to the end of the retaining spring 32 away from the abutting ball 31.

[0047] In this embodiment, the pre-tightening assembly 3 further includes a sealing plug 33, which is detachably disposed at the outer end of the mounting hole 11 and has an adjustable length extending into the mounting hole 11. One end of the sealing plug 33 extending into the mounting hole 11 is connected to the end of the retaining spring 32 away from the abutting ball 31. By adjusting the length of the sealing plug 33 extending into the mounting hole 11, the holding force of the retaining spring 32 on the abutting ball 31 can be adjusted, allowing the pre-tightening force of the retaining spring 32 to be precisely adjusted to accommodate underwater equipment of different weights, thus improving the versatility and adaptability of the device. At the same time, the sealing plug 33, as a sealing component, effectively prevents water from entering the mounting hole 11, improving the reliability and service life of the device in the underwater environment.

[0048] In this example, the sealing plug 33 is provided with a second sealing ring 6 in the circumferential direction to further improve the sealing effect.

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in some optional embodiments, the driving component 4 is an electromagnetic coil sleeved on the outside of the upper connector 1. The driving component 4 is located at the mounting hole 11 and is used to adjust the position of one end of the holding spring 32 against the abutting ball 31, so as to adjust the holding force of the holding spring 32 against the abutting ball 31.

[0050] In this embodiment, the driving component 4 is an electromagnetic coil sleeved on the outside of the upper connector 1. The driving component 4 is located at the mounting hole 11 and is used to adjust the position of one end of the holding spring 32 against the abutment ball 31, so as to adjust the holding force of the holding spring 32 against the abutment ball 31. By adopting an electromagnetic coil structure, the holding force of the holding spring 32 can be precisely adjusted through remote control to achieve a rapid and controllable disengagement operation of the underwater vehicle. At the same time, the driving component 4 serves as an auxiliary disengagement mechanism, forming a dual redundancy design with the mechanical disengagement method. When the driving component 4 is operating normally, it can achieve efficient disengagement. However, when the driving component fails (such as a power supply failure), it can still trigger mechanical disengagement by raising the upper connector 1 to generate tension. This effectively solves the problem that the rapid disengagement device based on pure electromagnetic adsorption in the prior art relies on the power supply system. If the power supply system fails, the operation using the rapid disengagement device based on pure electromagnetic adsorption will come to a standstill. The rapid disengagement device based on mechanical locking mechanism is generally more complex in structure and may fail in harsh environments. Both of these have the problem of difficulty in achieving stable rapid disengagement.

[0051] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some optional embodiments, the pretensioning assembly 3 further includes a metal top plate 34, the cross-sectional area of ​​which is greater than the maximum cross-sectional area of ​​the abutment ball 31. The metal top plate 34 is disposed at the end of the abutment spring 32 and is used to abut against the abutment ball 31.

[0052] In this embodiment, the pretensioning assembly 3 further includes a metal top plate 34. The cross-sectional area of ​​the metal top plate 34 is larger than the maximum cross-sectional area of ​​the abutment ball 31. The metal top plate 34 is disposed at the end of the abutment spring 32 and is used to abut against the abutment ball 31. This facilitates the connection between the abutment spring 32 and the abutment ball 31, and the metal top plate 34 can be better controlled by the magnetic force of the electromagnetic coil to adjust the position of the end of the abutment spring 32 abutting against the abutment ball 31.

[0053] In this example, the side of the metal top plate 34 that contacts the abutment ball 31 is provided with a connecting groove that matches the abutment ball 31, so as to facilitate the transmission of the holding force to the abutment ball 31.

[0054] like Figure 1 and Figure 4 As shown, in some optional embodiments, four mounting holes 11 are provided circumferentially spaced on the outer side of the upper connector 1, and the axis of the mounting holes 11 is arranged in the radial direction of the upper connector 1.

[0055] In this embodiment, four mounting holes 11 are provided circumferentially on the outer side of the upper connector 1. The axis of the mounting holes 11 is set along the radial direction of the upper connector 1, which realizes the uniform distribution of preload in the circumferential direction. This effectively avoids the problems of local stress concentration, connection deflection or structural deformation caused by uneven force in the traditional single-point connection method. Furthermore, the circumferential layout of the four mounting holes 11 further enhances the impact resistance of the connection. Even in the event of single-point failure, the basic connection function can still be maintained, providing a safer and more precise mechanical guarantee for the remote disengagement operation of the underwater vehicle.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, the portion of the lower connector 2 extending into the connecting cavity 12 matches the shape of the connecting cavity 12. The portion of the lower connector 2 extending into the connecting cavity 12 is divided into a large-diameter section and a small-diameter section. The large-diameter section is located at the opening of the connecting cavity 12, and the small-diameter section is provided with a groove 21.

[0057] In this embodiment, the portion of the lower connector 2 extending into the connecting cavity 12 matches the shape of the connecting cavity 12. The portion of the lower connector 2 extending into the connecting cavity 12 is divided into a large-diameter section and a small-diameter section. The large-diameter section is located at the opening of the connecting cavity 12, and the small-diameter section is provided with a groove 21. The stepped shape helps prevent debris from entering the small-diameter section and affecting the pre-tightening assembly 3, thereby improving the stability of the underwater vehicle's remote rapid disengagement device.

[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in some optional embodiments, a sealing ring mounting groove 22 is provided on the large diameter section, and the sealing ring mounting groove 22 is used to install the first sealing ring 5.

[0059] In this embodiment, a sealing ring mounting groove 22 is provided on the large-diameter section, which is used to install the first sealing ring 5. This achieves a highly reliable seal at the connection, effectively preventing moisture infiltration in the high-pressure underwater environment, avoiding corrosion of internal mechanical components, electrical short circuits, or seal failure, and significantly improving the stability and service life of the device in harsh underwater environments.

[0060] like Figures 1-8 As shown, on the other hand, this application also provides a method for using a remote rapid disengagement device for an underwater vehicle, which is implemented using the aforementioned remote rapid disengagement device for an underwater vehicle, and includes the following steps:

[0061] If a disengagement operation is performed and the drive assembly 4 is in normal operating condition, the drive retaining spring 32 moves to adjust the retaining force on the abutment ball 31. The abutment ball 31 is squeezed into the mounting hole 11 by the groove 21, so that the upper connector 1 and the lower connector 2 are separated.

[0062] If a disengagement operation is performed and the drive assembly 4 is in a stopped operating state, the upper connector 1 is raised at a set speed, generating a corresponding tension between the upper connector 1 and the lower connector 2. Under the action of the tension, the abutment ball 31 is squeezed into the mounting hole 11 by the groove 21, causing the upper connector 1 and the lower connector 2 to separate.

[0063] When using the underwater vehicle remote rapid disengagement device, the upper connector 1 is used to connect to the cable. The outer side of the upper connector 1 is provided with a mounting hole 11, and one end of the upper connector 1 is provided with a connecting cavity 12, which communicates with the mounting hole 11. The lower connector 2 is used to connect to the underwater equipment. One end of the lower connector 2 is used to extend into the connecting cavity 12. The part of the lower connector 2 that extends into the connecting cavity 12 is provided with a groove 21 corresponding to the mounting hole 11. The pre-tightening component 3 is disposed in the mounting hole 11. The pre-tightening component 3 includes an abutment ball 31 and a retaining spring 32. The abutment ball 31 is used to abut in the groove 21, and the retaining spring 32 is used to abut on the abutment ball 31. The drive component 4 is disposed on the upper connector 1 and is used to drive the retaining spring 32 to move to adjust the retaining force on the abutment ball 31. If a disengagement operation is performed and the drive assembly 4 is in normal operating condition, the drive retaining spring 32 moves, adjusting the retaining force on the abutment ball 31. The abutment ball 31 is compressed by the groove 21 and retracts into the mounting hole 11, separating the upper connector 1 and the lower connector 2. If a disengagement operation is performed and the drive assembly 4 is in a stopped operating condition, the upper connector 1 is raised at a set speed, generating a corresponding tension between the upper connector 1 and the lower connector 2. Under the action of the tension, the abutment ball 31 is compressed by the groove 21 and retracts into the mounting hole 11, separating the upper connector 1 and the lower connector 2. Since the drive assembly 4 can complete the disengagement operation in both normal and stopped operating conditions, it has good stability. This solves the problem that existing rapid disengagement devices using pure electromagnetic adsorption rely on a power supply system. If the power supply system fails, the operation using the rapid disengagement device using pure electromagnetic adsorption will come to a standstill. Rapid disengagement devices using mechanical locking mechanisms generally have a more complex structure and may fail in harsh environments, both of which have the problem of difficulty in achieving stable rapid disengagement.

[0064] In some optional embodiments, prior to performing the disconnection operation, the following steps are also included:

[0065] The preload of the retaining spring 32 is obtained based on the weight of the underwater equipment;

[0066] Based on the preload of the retaining spring 32, the physical parameters of the retaining spring 32 are determined.

[0067] In this embodiment, before the disengagement operation, the following steps are included: obtaining the preload of the retaining spring 32 based on the weight of the underwater equipment; and determining the physical parameters of the retaining spring 32 based on the preload of the retaining spring 32. Accurately calculating the preload of the retaining spring 32 based on the weight of the underwater equipment before the disengagement operation effectively solves the connection reliability problem caused by the inability of a fixed preload design to adapt to changes in equipment weight. This design ensures a dynamic balance between the preload and the actual weight of the underwater equipment, avoiding both the risk of accidental disengagement due to insufficient preload and the difficulty of disengagement caused by excessive preload, significantly improving the adaptability and stability of the device in different operating scenarios.

[0068] In some alternative embodiments, determining the physical parameters of the retaining spring 32 based on its preload includes:

[0069] The compression amount when the preset retaining spring 32 provides preload force;

[0070] The stiffness of the retaining spring 32 is determined based on the preload of the retaining spring 32 and the amount of compression of the retaining spring 32 in the preloaded state.

[0071] In this embodiment, the physical parameters of the retaining spring 32 are determined based on its preload. Specifically, this includes: presetting the compression amount of the retaining spring 32 when it provides preload; and determining the stiffness of the retaining spring 32 based on its preload and the compression amount in the preloaded state. The compression amount of the retaining spring 32 when it provides preload must conform to the actual situation of the mounting hole 11, so it is preset in advance. Subsequently, the stiffness of the retaining spring 32 can be quickly calculated using its preload and the compression amount in the preloaded state, facilitating design.
