[0052] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.
[0053] Example
[0054] Figure 1 Schematic diagram of a partial structure of an umbilical cable retracting and releasing system 100 in one embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of a portion of the structure of the umbilical cable retracting and releasing system 100 in the illustrated embodiment from another perspective; Figure 3 for Figure 1 A partial schematic diagram of an umbilical cable recovery and deployment system 100 in the illustrated embodiment.
[0055] See also Figures 1 to 3 This embodiment provides an umbilical cable retracting and releasing system 100 , including a winch 10 , a drum 20 , a cable arrangement mechanism 30 , a first pneumatic motor 40 , a second pneumatic motor 50 and an air source 60 .
[0056] The drum 20 is located within the winch 10 and is used to wind the umbilical cable. A cable arrangement mechanism 30 is located on the winch 10 and includes a screw 31 and a bracket 32, with the bracket 32 mounted on the screw 31. A first pneumatic motor 40 is connected to the drum 20 and is used to drive the drum 20 in forward and reverse rotation. A second pneumatic motor 50 is connected to the cable arrangement mechanism 30 and is used to drive the screw 31 to reciprocate along the axis of the drum 20, thereby allowing the bracket 32 to arrange the umbilical cable on the drum 20. An air source 60 is used to supply air to the first and second pneumatic motors 40 and 50.
[0057] The umbilical cable retraction and deployment system 100 utilizes a first pneumatic motor 40 to drive the drum 20 in forward and reverse rotation to retract and deploy the umbilical cable, thereby enabling the umbilical cable to provide optical, electrical, and other media and control signals to underwater equipment at different depths. A second pneumatic motor 50 drives the cable arrangement mechanism 30, which arranges the umbilical cable on the drum 20, ensuring an orderly arrangement and preventing entanglement. Because both the first and second pneumatic motors 40, 50 are pneumatically driven, the explosion-proof potential associated with electrical drives is avoided, thereby enhancing the safety of the umbilical cable retraction and deployment system 100.
[0058] In some embodiments, as Figure 3 As shown, the umbilical cable retraction and deployment system 100 also includes a reel control valve 70 and a cable spool control valve 80. The air inlet of the reel control valve 70 is connected to the air source 60, and the working end of the reel control valve 70 is connected to the air inlet and air outlet of the first pneumatic motor 40, respectively. The air inlet of the cable spool control valve 80 is connected to the air source 60, and the working end of the cable spool control valve 80 is connected to the air inlet and air outlet of the second pneumatic motor 50, respectively. As both the reel control valve 70 and the cable spool control valve 80 are pneumatic valves, the explosion-proof risks associated with using solenoid valves are avoided, thereby further improving the explosion-proof rating of the umbilical cable retraction and deployment system 100.
[0059] Figure 4 for Figure 1 Schematic diagram of the local console 120 in the illustrated embodiment.
[0060] In some embodiments, as Figure 3 and Figure 4As shown, the umbilical cable retraction and deployment system 100 further includes a first local control valve 90 and a second local control valve 110. The working end of the first local control valve 90 is connected to the control end of the reel control valve 70, and the working end of the second local control valve 110 is connected to the control end of the cable arrangement control valve 80. In this manner, the first local control valve 90 can be operated to change the working position of the reel control valve 70, thereby controlling the reel 20 to retract and deploy the umbilical cable. Furthermore, the second local control valve 110 can be operated to change the working position of the cable arrangement control valve 80, thereby controlling the screw rod 31 to drive the bracket 32 to deflect forward or backward, thereby adjusting the arrangement of the umbilical cable on the reel 20.
[0061] In some embodiments, as Figure 1 and Figure 4 As shown, the umbilical cable retraction and deployment system 100 further includes a local control console 120, which is disposed on the winch 10. The first local control valve 90 and the second local control valve 110 are respectively disposed on the local control console 120, so that the reel 20 and the cable arrangement mechanism 30 can be respectively controlled on the local control console 120. Optionally, the first local control valve 90 and the second local control valve 110 are respectively controlled by handles on the local control console 120.
[0062] Figure 5 for Figure 1 Schematic diagram of the remote control console 160 in the illustrated embodiment.
[0063] In some embodiments, as Figures 3 to 5 As shown, the umbilical cable retraction and deployment system 100 also includes a first remote control valve 130, a second remote control valve 140, and a switching valve 150. The first remote control valve 130 is connected to the control end of the reel control valve 70, and the second remote control valve 140 is connected to the control end of the cable arrangement control valve 80. The switching valve 150 is located on the local control console 120. The air source 60 can be selectively connected to the first local control valve 90 and the second local control valve 110, or to the first remote control valve 130 and the second remote control valve 140, respectively, through the switching valve 150. This allows the reel 20 and the cable arrangement mechanism 30 to be controlled either locally or remotely, improving operational flexibility and enabling convenient switching via the switching valve 150 on the local control console 120.
[0064] Figure 6 for Figure 1 A schematic diagram of a partial structure of an umbilical cable retraction and deployment system 100 in the illustrated embodiment.
[0065] In some embodiments, as Figure 5 and Figure 6As shown, the umbilical cable recovery and deployment system 100 also includes a remote control console 160, which is located outside the winch 10. The first remote control valve 130 and the second remote control valve 140 are respectively installed on the remote control console 160. This facilitates remote control of the drum 20 and the winch 10 from the remote control console 160, and the location of the remote control console 160 can be adjusted according to usage needs. Optionally, the first remote control valve 130 and the second remote control valve 140 are respectively controlled by a handle on the remote control console 160.
[0066] In some embodiments, as Figure 6 As shown, the umbilical cable retraction and deployment system 100 also includes a reducer and a transmission device 180. The reducer is connected to the drum 20. The first pneumatic motor 40 is connected to the reducer through the transmission device 180 to drive the drum 20 to rotate forward or reverse to achieve the retraction and deployment of the umbilical cable. Optionally, the reducer is a built-in planetary reducer. The drive shaft leading from the reducer input end is connected through a first right-angle deflector, an offset adjuster, a second right-angle deflector, and the screw 31 of the cable arrangement mechanism 30. The screw 31 of the cable arrangement mechanism 30 is a bidirectional screw 31. For each rotation of the drum 20, the cable arrangement mechanism 30 travels an axial distance of 1.03 to 1.05 times the diameter of the umbilical cable.
[0067] In some embodiments, as Figure 2 As shown, the transmission 180 comprises a sprocket and chain transmission.
[0068] In other embodiments, the transmission device 180 includes a gear transmission device (not shown).
[0069] In some embodiments, as Figure 1 As shown, the umbilical cable retracting and releasing system 100 further includes a parking brake device 190, which is provided on the winch 10 and is used to stop the drum 20. In other embodiments, the parking brake device 190 can be replaced by a caliper disc brake.
[0070] In some embodiments, as Figure 3 As shown, the winch 10 has a tension limiting function to prevent the tension on the umbilical cable from exceeding a safe value, thereby protecting the safety of the cable and equipment.
[0071] In some embodiments, as Figure 6 As shown, the winch 10 includes a frame 11 and a grille 12 . The frame 11 is provided with a cable outlet. The grille 12 is provided on the frame 11 and covers the portion outside the cable outlet to further improve the safety performance of the winch 10 .
[0072] In some embodiments, two bearing seats are provided in the frame 11 , and the two ends of the reel 20 are placed on the two bearing seats respectively.
[0073] In some embodiments, the winch 10 includes a vehicle body and a vehicle door, wherein the vehicle door is movably mounted on the vehicle body. Figure 3 As shown, the umbilical cable retraction and deployment system 100 further includes an interlock valve 210. The interlock valve 210 is configured to block the air supply from the air source 60 to the first air motor 40 and the second air motor 50 when the vehicle door is opened. Thus, when the vehicle door is opened, the interlock valve 210 automatically stops the winch 10, preventing accidents caused by operator error and further improving safety.
[0074] In some embodiments, the local console 120 and the remote console 160 are connected to the pneumatic control components within the winch 10 via pipes. Because the winch 10 is pneumatically driven and all pneumatic control components are pneumatically controlled, the explosion-proof hazards caused by solenoid valves are avoided, making it suitable for work areas with high explosion-proof levels.
[0075] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
