Detailed Implementation

[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] like Figures 1 to 4As shown, according to an embodiment of this disclosure, a locking device for recovering an underwater vehicle is proposed, comprising: a lifting assembly 100 for mounting on a lifting device, the lifting assembly 100 including a first base 110, a first magnetic element 120 and a first lifting buckle 130, the first magnetic element 120 being disposed within the first base 110 and the first lifting buckle 130 being disposed on the first base 110; and a locking hook assembly 200 for mounting on the underwater vehicle, the locking hook assembly 200 including a second base 210 and a second magnetic element 220. The lock hook body 230 and the drive unit 240 are provided. The second magnetic element 220 is disposed in the second base 210 and the drive unit 240 is disposed in the second base 210 and connected to the lock hook body 230. The second base 210 is formed with a hook insertion port 2102 for the first hook 130 to extend into or retract. The first magnetic element 120 is adapted to generate magnetic attraction between itself and the second magnetic element 220. The drive unit 240 is used to drive the lock hook body 230 to hook or separate from the first hook 130 in the hook insertion port 2102.

[0019] The locking device for recovering an underwater vehicle provided in this embodiment includes the aforementioned lifting assembly 100 and locking hook assembly 200. In practical applications, the lifting assembly 100 and locking hook assembly 200 are respectively used to mount the lifting device's lifting attachment and the underwater vehicle. The lifting assembly 100 includes a first base 110, a first magnetic element 120, and a first lifting buckle 130. Both the first magnetic element 120 and the first lifting buckle 130 are disposed on the first base 110. The first magnetic element 120 is located inside the first base 110, thereby improving the installation stability of the first magnetic element 120 and reducing the risk of it falling off. The locking hook assembly 200 includes a second base 210, a second magnetic element 220, a locking hook body 230, and a driving part 240. Both the second magnetic element 220 and the locking hook body 230 are disposed on the second base 210. The second magnetic element 220 is located inside the first base 110. The second base 210 is located inside, thereby improving the installation stability of the second magnetic component 220 and reducing the risk of the second magnetic component 220 falling off. The second base 210 is formed with a hook socket 2102. The first hook 130 is adapted to extend into or out of the hook socket 2102. The drive unit 240 is connected to the hook body 230 and is used to drive the hook body 230 to move, so as to hook or separate the first hook 130 in the hook socket 2102, so that the hook assembly 100 is correspondingly locked or can be separated from the hook assembly 200. Magnetic attraction can be generated between the aforementioned first magnetic component 120 and second magnetic component 220. In practical applications, when it is necessary to connect the lifting device's lifting attachment to an underwater vehicle, the lifting buckle assembly 100 can be pre-connected to the aforementioned lifting attachment. The lifting device can then move the lifting buckle assembly 100 above the locking hook assembly 200 installed on the underwater vehicle, ensuring that the first lifting buckle 130 and the lifting buckle socket 2102 are vertically aligned or approximately aligned. The lifting device can then drive the lifting buckle assembly 100 downwards, allowing the first lifting buckle 130 to extend into the lifting buckle socket 2102. During the process of the first lifting buckle 130 approaching and extending into the lifting buckle socket 2102, the first magnetic element 120 and the second magnetic element 220 can attract each other, reducing the risk of the lifting buckle assembly 100 deviating from the locking hook assembly 200 during descent, thus facilitating the first lifting... The first hook 130 is securely inserted into the hook socket 2102, and when the first hook 130 is inserted into the hook socket 2102, the magnetic attraction between the first magnetic component 120 and the second magnetic component 220 can also ensure the relative positional stability between the hook assembly 100 and the locking hook assembly 200, reducing the risk of the first hook 130 coming out of the hook socket 2102. This makes it easier to control the drive unit 240 to drive the locking hook body 230 to hook onto the first hook 130, thus realizing the connection between the aforementioned lifting device and the underwater vehicle. After the locking hook body 230 hooks onto the first hook 130 in the hook socket 2102, the lifting device can lift the underwater vehicle to the target recovery position to complete the underwater vehicle recovery operation.Based on this, the locking device for recovering underwater vehicles provided in this embodiment can reduce the manpower consumption when connecting the lifting device and the underwater vehicle during the recovery operation, eliminating the need for operators to board the vessel, thus improving the convenience and safety of the recovery operation and increasing the efficiency of the underwater vehicle recovery operation.

[0020] Understandably, the first base 110 may have a first connecting end 1101, and the first hook 130 may protrude from the first connecting end 1101 to facilitate the first hook 130's engagement with an external structure; the second base 210 may have a second connecting end 2101 corresponding to the aforementioned first connecting end 1101, and a hook insertion port 2102 may be formed on the second connecting end 2101. The first connecting end 1101 is adapted to abut against the second connecting end 2101. Accordingly, when the first hook 130 extends into the hook insertion port 2102, the first connecting end 1101 abuts against the second connecting end 2101, thereby improving the stability of the hook assembly 100 and the locking hook assembly 200 during engagement.

[0021] It is understood that at least one of the aforementioned first magnetic element 120 and the aforementioned second magnetic element 220 is a magnet. When one of the first magnetic element 120 and the second magnetic element 220 is a magnet, the other can be made of a ferromagnetic material, so that when the first magnetic element 120 and the second magnetic element 220 are brought close to each other, a magnetic attraction can be generated between them. When both the first magnetic component 120 and the second magnetic component 220 are magnets, the first magnetic component 120 may have a first magnetic end 1201 facing the first connecting end 1101, and the second magnetic component 220 may have a second magnetic end 2201 facing the second connecting end 2101. Accordingly, the polarity of the first magnetic end 1201 is opposite to that of the second magnetic end 2201; that is, when the polarity of the first magnetic end 1201 is N, the polarity of the second magnetic end 2201 is S, or when the polarity of the first magnetic end 1201 is S, the polarity of the second magnetic end 2201 is N. The specific polarities of the first magnetic end 1201 and the second magnetic end 2201 can be set according to actual needs, and are not limited here.

[0022] Understandably, in practical applications, the lifting hook assembly 100 and the lifting device's spreader can be detachably connected. This allows the lifting hook assembly 100 to be removed from the lifting device's spreader after the underwater vehicle's recovery operation is completed, facilitating other lifting operations. The locking hook assembly 200 can be fixedly mounted on the underwater vehicle's hull, ensuring the reliability of the connection between the locking hook assembly 200 and the underwater vehicle, thus providing a guarantee for the stable lifting of the underwater vehicle.

[0023] It is understandable that when the hook assembly 200 is installed on an underwater vehicle, the hook socket 2102 can be arranged upward along the direction of gravity. Correspondingly, when the hook assembly 100 is installed on the lifting device, the first hook 130 can be arranged downward along the direction of gravity to facilitate the docking of the first hook 130 with the hook socket 2102.

[0024] In some feasible examples, the locking device for recovering an underwater vehicle further includes a remote control component, wirelessly connected to the drive unit 240, for controlling the operation of the drive unit 240. Therefore, the aforementioned locking device can utilize the remote control component to wirelessly control the operation of the drive unit 240 during use, improving the ease of operation control of the drive unit 240.

[0025] In some feasible examples, the locking device for recovering an underwater vehicle further includes a control component disposed on the second base 210. The control component is signal-connected to the drive unit 240, and is configured to control the drive unit 240 to drive the hook body 230 to hook onto the first hook 130 within the hook socket 2102 when the first hook 130 extends into the hook socket 2102 and the first connecting end 1101 abuts against the second connecting end 2101. Based on this, the aforementioned locking device can automatically control the drive unit 240 to operate after the hook assembly 100 and the hook assembly 200 are aligned and attracted during use, so that the hook body 230 hooks onto the first hook 130, thereby improving the ease of use of the aforementioned locking device. For example, the aforementioned control component may include a Hall sensor.

[0026] like Figure 2 and Figure 4 As shown, in one feasible embodiment, the first base 110 includes: a first housing 111 having a first connecting end 1101, the first connecting end 1101 having a first receiving groove and a first connecting hole 1112, the first housing 111 having a mounting groove 1113 on the side opposite to the first connecting end 1101, the first connecting hole 1112 communicating with the mounting groove 1113, and a first magnetic element 120 disposed in the first receiving groove; a mounting plate 112 detachably disposed in the mounting groove 1113, a first hook 130 connected to the mounting plate 112 and passing through the first connecting hole 1112; and a cover plate 113 detachably disposed in the first housing 111 for opening or covering the opening of the mounting groove 1113.

[0027] In this technical solution, the first base 110 may include the aforementioned first housing 111, mounting plate 112, and cover plate 113. Based on the aforementioned configuration, the first base 110 can utilize the first receiving groove of the first housing 111 to accommodate the first magnetic component 120, thereby ensuring the installation stability of the first magnetic component 120; the first hook 130 is disposed on the mounting plate 112 and passes through the first connecting hole 1112 of the first housing 111, thereby allowing the first hook 130 to protrude from the aforementioned first connecting end 1101, facilitating the docking of the first hook 130 with an external structure; the mounting plate 112 is detachably disposed within the aforementioned mounting groove 1113, thereby facilitating the assembly and disassembly of the first hook 130 on the first housing 111, and making it convenient to replace the first hook 130; the cover plate 113 can open or cover the opening of the aforementioned mounting groove 1113 to facilitate the assembly and disassembly of the mounting plate 112 and the first hook 130, or to ensure the installation stability of the mounting plate 112 and the first hook 130.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, in one feasible embodiment, the mounting plate 112 is movably disposed within the mounting groove 1113. The lifting buckle assembly 100 further includes: a second lifting buckle 140 connected to the side of the mounting plate 112 opposite to the first lifting buckle 130; the cover plate 113 has a second connecting hole 1131; when the cover plate 113 is disposed on the first housing 111, the second lifting buckle 140 passes through the second connecting hole 1131 and protrudes from the side of the cover plate 113 opposite to the first housing 111; the second lifting buckle 140 is used to connect a lifting device; a first elastic telescopic member 150, one end of which is connected to the mounting plate 112, and the other end of which is used to abut against the cover plate 113; and a second elastic telescopic member 160 connected between the inner bottom wall of the mounting groove 1113 and the mounting plate 112.

[0029] In this technical solution, the lifting assembly 100 may further include the aforementioned second lifting buckle 140, first elastic telescopic member 150, and second elastic telescopic member 160. Based on the aforementioned configuration, on the one hand, the lifting assembly 100 can be connected to the lifting device's lifting tool via the second lifting buckle 140, which can improve the connection reliability between the lifting assembly 100 and the aforementioned lifting tool; on the other hand, the mounting plate 112 can be elastically connected between the cover plate 113 and the inner bottom wall of the mounting groove 1113 via the first elastic telescopic member 150 and the second elastic telescopic member 160. Correspondingly, the mounting plate 112, the first lifting buckle 130, and the second lifting buckle 140 can elastically float relative to the first housing 111 and the cover plate 113, thereby facilitating the use of the elastic deformation of the first elastic telescopic member 150 and the second elastic telescopic member 160 during use to compensate for the traction gap of the first lifting buckle 130 and the second lifting buckle 140, and elastically buffering the changes in tension during the lifting process. This is beneficial to improving the structural reliability and stability of the lifting assembly 100, and provides a guarantee for the stable and reliable lifting and recovery of underwater vehicles.

[0030] like Figure 4 As shown, in one feasible embodiment, there are multiple first receiving slots, each first receiving slot is provided with at least one first magnetic element 120, and the multiple first receiving slots are arranged around the first connecting hole 1112.

[0031] In this technical solution, the quantity and layout of the first receiving groove and the first magnetic component 120 are constrained. Based on the aforementioned configuration, multiple first magnetic components 120 can be distributed around the first hook 130. Correspondingly, a uniform and high-intensity magnetic field can be formed around the first hook 130 during use. This can enhance the magnetic attraction strength and uniformity between the first magnetic component 120 and the second magnetic component 220 during the docking of the first hook 130 with the hook socket 2102, ensuring the smooth insertion of the first hook 130 into the hook socket 2102 and reducing the risk of the first hook 130 falling out of the hook socket 2102.

[0032] like Figure 4 As shown, in one feasible embodiment, the hook assembly 100 further includes: a first magnetic sheet 170, disposed in the first receiving groove and arranged on the side of the first magnetic element 120 opposite to the first connecting end 1101.

[0033] In this technical solution, the hook assembly 100 may further include the aforementioned first magnetic sheet 170. Based on the aforementioned configuration, the hook assembly 100 can utilize the first magnetic sheet 170 to weaken the magnetic field strength on the side of the first magnetic element 120 away from the first connecting end 1101 and enhance the magnetic field strength on the side of the first magnetic element 120 facing the first connecting end 1101. This facilitates the formation of a stronger magnetic attraction between the first magnetic element 120 and the second magnetic element 220, further facilitating the docking of the first hook 130 with the hook socket 2102.

[0034] It is understandable that the first magnetic sheet 170 can be made of a soft magnetic material, which can be, but is not limited to, pure iron, low carbon steel, silicon steel sheet, permalloy, etc.

[0035] like Figure 3 and Figure 4 As shown, in one feasible embodiment, the second base 210 includes: a mounting frame 211 for mounting on an underwater vehicle, and a drive unit 240 mounted on the mounting frame 211; a second housing 212 mounted on the mounting frame 211, the second housing 212 having a second connecting end 2101, the second connecting end 2101 having a second receiving groove 2121 and a hook insertion port 2102, and a second magnetic element 220 disposed in the second receiving groove 2121.

[0036] In this technical solution, the second base 210 may include the aforementioned mounting bracket 211 and the second housing 212. Based on the aforementioned configuration, the second base 210 can utilize the second receiving groove 2121 of the second housing 212 to accommodate the second magnetic component 220, thereby ensuring the installation stability of the second magnetic component 220; the mounting bracket 211 is used to connect the second housing 212 and the underwater vehicle, and can provide an installation position for the drive unit 240 and the hook body 230, thereby ensuring the overall structural stability and reliability of the hook assembly 200.

[0037] For example, the second housing 212 can be an annular structure, the aforementioned second connecting end 2101 can be one end of the second housing 212 in the axial direction, and the aforementioned hook insertion port 2102 can include a central through hole of the second housing 212. Correspondingly, the driving part 240 can drive the locking hook body 230 to extend into or out of the aforementioned central through hole, so that the locking hook body 230 can hook or separate from the first hook 130 in the central through hole.

[0038] For example, the mounting bracket 211 has a guide hole, one end of which is connected to the aforementioned central through hole. The locking hook body 230 passes through the guide hole, and the driving part 240 can drive the locking hook body 230 to slide along the guide hole so that the locking hook body 230 extends into or out of the aforementioned central through hole through the end of the guide hole connected to the aforementioned central through hole.

[0039] like Figure 3 and Figure 4 As shown, in one feasible embodiment, there are multiple second receiving slots 2121, each second receiving slot 2121 is provided with at least one second magnetic element 220, and the multiple second receiving slots 2121 are arranged around the hook insertion port 2102.

[0040] In this technical solution, the quantity and layout of the second receiving groove 2121 and the second magnetic component 220 are constrained. Based on the aforementioned configuration, multiple second magnetic components 220 can be distributed around the hook socket 2102. Correspondingly, a uniform and high-intensity magnetic field can be formed around the hook socket 2102 during use. This can enhance the magnetic attraction strength and uniformity between the first magnetic component 120 and the second magnetic component 220 during the docking of the first hook 130 and the hook socket 2102, ensuring the smooth insertion of the first hook 130 into the hook socket 2102 and reducing the risk of the first hook 130 falling out of the hook socket 2102.

[0041] It is understandable that when multiple first receiving slots are arranged around the first connecting hole 1112, and each first receiving slot is provided with at least one first magnetic element 120, the arrangement and specific number of the multiple first receiving slots on the first connecting end 1101 can be matched with the arrangement and specific number of the multiple second receiving slots 2121 on the second connecting end 2101. Accordingly, the number of first magnetic elements 120 provided in the first receiving slot is the same as the number of second magnetic elements 220 provided in the second receiving slot 2121, so as to further improve the magnetic attraction strength and uniformity between the first magnetic element 120 and the second magnetic element 220 during the docking of the second hook 140 and the hook socket 2102.

[0042] like Figure 4 As shown, in one feasible embodiment, the locking hook assembly 200 further includes: a second magnetic sheet 250, disposed in the second receiving groove 2121 and arranged on the side of the second magnetic element 220 opposite to the second connecting end 2101.

[0043] In this technical solution, the locking hook assembly 200 may further include the aforementioned second magnetic sheet 250. Based on the aforementioned configuration, the locking hook assembly 200 can utilize the second magnetic sheet 250 to weaken the magnetic field strength on the side of the second magnetic element 220 away from the second connecting end 2101, and enhance the magnetic field strength on the side of the second magnetic element 220 facing the second connecting end 2101. This facilitates the formation of a stronger magnetic attraction between the first magnetic element 120 and the second magnetic element 220, further facilitating the docking of the first hook 130 with the hook insertion port 2102.

[0044] It is understandable that the second magnetic sheet 250 can be made of soft magnetic material, which can be, but is not limited to, pure iron, low carbon steel, silicon steel sheet, permalloy, etc.

[0045] like Figure 4 As shown, in one feasible embodiment, the drive unit 240 includes: a drive motor 241 disposed on the second base 210; and a flexible coupling 242 connected between the drive motor 241 and the locking hook body 230.

[0046] In this technical solution, the drive unit 240 may include the aforementioned drive motor 241 and flexible coupling 242. Based on the aforementioned configuration, the drive unit 240 can provide motion power to the hook body 230 through the drive motor 241 to ensure that the hook body 230 can stably and reliably hook or detach from the first hook 130. The drive motor 241 can be flexibly connected to the hook body 230 through the flexible coupling 242, thereby facilitating the absorption of fit errors between the hook body 230 and other components by utilizing the flexible coupling 242. This reduces the risk of the hook body 230 jamming during movement and provides a guarantee for the stable and reliable hooking or detachment of the hook body 230 from the first hook 130.

[0047] In one feasible implementation, the first magnetic element 120 and the second magnetic element 220 are both Hellbeck array magnets.

[0048] In this technical solution, both the first magnetic element 120 and the second magnetic element 220 are Hellbeck array magnets. The first magnetic end 1201 and the second magnetic end 2201 can be the strong magnetic side of the first magnetic element 120 and the second magnetic element 220, respectively. Furthermore, the polarity of the first magnetic end 1201 is opposite to that of the second magnetic end 2201. Based on this, the first magnetic end 1201 and the second magnetic end 2201 can form a stronger magnetic field, which can enhance the magnetic attraction between the first magnetic element 120 and the second magnetic element 220 and reduce the magnetic force on the first magnetic element 120. The magnetic field strength of the side of the first connecting end 1101 and the side of the second magnetic component 220 that is away from the second connecting end 2101 is reduced, thereby reducing the magnetic influence on the components in the corresponding positions. This improves the magnetic energy utilization efficiency of the first magnetic component 120 and the second magnetic component 220. It is beneficial to improve the magnetic attraction strength and uniformity between the first magnetic component 120 and the second magnetic component 220 during the docking process of the first hook 130 and the hook socket 2102. This ensures that the first hook 130 can be smoothly inserted into the hook socket 2102 and reduces the risk of the first hook 130 falling out of the hook socket 2102.

[0049] In this disclosure, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise expressly defined.
