Description

Technical Field

[0001] This invention relates to the technical field of connection devices, and more specifically to an underwater power transmission and communication connection device with interchangeable installation methods. Background Technology

[0002] In existing technologies, underwater connection devices used for power transmission and communication generally have two structural forms. One form involves a flange for device fixation fixed to the pin end, which in turn secures the pin end to the underwater equipment. A handle for device insertion and removal is fixed to the socket end, and connection and disconnection can only be performed by operating the socket end. The other form is the complete opposite of the first. Because the cable tail tube at the device's tail end often has a certain bending angle and is sealed with sealant, it conflicts with the installation and disassembly of related unlocking mechanisms, flanges, etc. Installation and disassembly must be performed in a fixed sequence, ultimately resulting in a single installation and fixing method for current underwater connection devices on the market, making it impossible to change the installation method by replacing its own components. This is extremely detrimental to enterprises in reducing production and processing costs. Each structural form requires the development of a new processing technology and the addition of a processing production line, which undoubtedly increases the enterprise's investment in manpower and resources. Simultaneously, for users, changes in the installation and fixing method of the underwater connection device or changes in the usage scenario (from requiring the pin end as the fixing end to requiring the socket end as the fixing end, and vice versa), such as changes in the power supply end and the power receiving end, directly render the original product unusable. In this case, users must purchase a new set of underwater connection devices, which undoubtedly increases usage costs. Therefore, while the existing two structural forms bring convenience, they also increase the burden of use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a solution to the problem that the installation form of the underwater connection device used for power transmission communication in the prior art is fixed and cannot be replaced. This avoids the problem that a new underwater connection device must be purchased due to the replacement of the fixed object during the application process, thereby increasing its versatility and bringing great convenience to enterprises and users.

The universal unlocking ring 35 is coaxially fitted on the sixth cylindrical surface 338 of the socket end unlocking housing 36 and the two are fixed relative to each other by screws. The mounting cutout 351 corresponds one-to-one with the clearance cutout 331 on the socket end unlocking housing 36, and the positioning protrusion 353 contacts the corresponding end face of the socket end unlocking housing 36. Each of the second positioning grooves 214 has a corresponding locking member 34 installed. Each locking member 34 is located in the corresponding clearance cut 331 on the unlocking housing 36 at the insertion end. The mounting head 341 of the locking member 34 is fixed in the corresponding second positioning groove 214 by a screw that passes through the fourth pin hole 342 and is tightened in the third threaded hole 215. The locking head 343 of the locking member 34 passes over the positioning body 335 at the outer end of the corresponding clearance cut 331 and extends into the corresponding mounting cut 351. The pin-end unlocking housing 33 is coaxially fitted onto the outside of the pin mounting housing 11. A screw extending into the corresponding first pin hole 112 is threaded into the second threaded hole 333 on the pin-end unlocking housing 33 to fix the pin-end unlocking housing 33 onto the pin mounting housing 11. The flange 41 and the universal protective ring 37 are both coaxially fixed to the fourth cylindrical surface 336 of the pin-end unlocking housing 33 by screws. The flange 41 is fixed to the underwater equipment.

[0046] The working process and principle of this invention:

[0047] This invention discloses an underwater power transmission and communication connection device with interchangeable installation methods. Since the pin-end unlocking housing 33 and the socket-end unlocking housing 36 have the same external dimensions and a universal interface, and the pin mounting housing 11 and the socket mounting housing 21 adopt the same structure at the fixing locking member 34, the universal unlocking ring 35, locking member 34, universal fixing ring 32, fixing component and universal protective ring 37 can be interchanged and fixed at corresponding positions on the pin end 100 and the socket end 200. During the insertion process of the pin end 100 and the socket end 200, guidance and connection unlocking are essential. In particular, the pin end 100 and the socket end 200 still need to have these two functions before and after switching the working mode (switching between the two working modes of static fixing and sliding unlocking).

[0048] When the pin end 100 is in the sliding unlocking mode and the socket end 200 is in the stationary fixed mode, refer to Figure 1 As shown; the universal unlocking ring 35, universal fixing ring 32, and combination handle 31 are fastened to the corresponding positions of the pin-end unlocking housing 33 by screws; the locking member 34 is fastened to the first positioning groove 18 of the pin mounting housing 11 by screws; the pin-end unlocking housing 33 can slide relative to the pin mounting housing 11 by a certain distance; the flange 41 and universal protective ring 37 are fastened to the corresponding positions of the socket-end unlocking housing 36 by screws; the flange 41 is fixed to the underwater equipment; the socket-end unlocking housing 36 and the socket mounting housing 21 are relatively fixed by set screws; at the pin end 100... During the insertion process of the pin 100 into the socket end 200, the guide cutout 332 on the socket end unlocking housing 36 and the guide cutout 332 on the pin end unlocking housing 33 correspond to each other. The guide cylinder 217 on the socket mounting housing 21 engages with the U-shaped guide cutout 332 on the pin end unlocking housing 33 to achieve guidance and prevent fooling during insertion and removal. After the pin end 100 is inserted into the socket end 200, the locking head 343 of the locking member 34 fixed on the pin mounting housing 11 engages with the positioning body 335 at the front end of the clearance cutout 331 on the socket end unlocking housing 36, forming a reliable connection. Figure 11 As shown; when the pin end 100 is pulled out of the socket end 200, the combination handle 31 is manually pulled, which in turn drives the pin end unlocking housing 33 and the universal unlocking ring 35 to move axially. The driving inclined surface 352 set on the inner end of the mounting notch 351 on the universal unlocking ring 35 cooperates with the inverted inclined surface 344 on the locking member 34's latch 343. That is, the driving inclined surface 352 pushes the latch 343 of the locking member 34 outward through the inverted inclined surface 344, causing the latch 343 to move outward and disengage from the corresponding connecting body. The reliable connection formed between the locking member 34 fixed on the pin mounting housing 11 and the positioning body 335 on the outer end of the clearance notch 331 on the socket end unlocking housing 36 is released, achieving the purpose of unlocking; conversely, when the pin end 100 is in a static fixed working mode and the socket end 200 is in a sliding unlocking working mode, refer to Figure 4 As shown, the universal unlocking ring 35, universal fixing ring 32, and combination handle 31 are fastened to the corresponding parts of the socket end unlocking housing 36 by screws. The locking element 34 is fastened to the socket mounting housing 21 by screws. The socket end unlocking housing 36 and the socket mounting housing 21 can slide relative to each other by a certain distance. The flange 41 and universal protective ring 37 are fastened to the pin end unlocking housing 33 by screws. The flange 41 is fixed on the underwater equipment. The pin end unlocking housing 33 and the pin mounting housing 11 are fixed relative to each other by set screws. In this state, its working principle is the same as that when the pin end 100 is in the sliding unlocking mode and the socket end 200 is in the stationary fixed mode.
