Description

Technical Field

[0001] This invention relates to the field of underwater vehicles, and more particularly to an ultra-deep ballast jettisoning device. Background Technology

[0002] Unmanned underwater vehicles (UUVs) have been widely used in underwater exploration due to their automatic route planning and autonomous navigation. However, when encountering strong ocean currents or sudden changes in seawater density, UUVs may experience extreme depth travel due to limitations in their control capabilities. This is especially true for low-speed vehicles, where reaching extreme depths makes surfacing difficult and can damage the vehicle's structural strength. Larger UUVs have internal water storage compartments that allow them to surface by dewatering in extreme depths; smaller UUVs mostly use ballast jettisoning. Common methods include depth detection via pressure sensors, signaling the control unit to release the ballast, electromagnetic adsorption, or explosive bolts. Electromagnetic adsorption requires the UUV to provide control programs and energy for extended periods, while explosive bolts pose a pyrotechnic risk and are detrimental to noise reduction and safety.

[0003] There is currently no effective solution to the problems with the electromagnetic adsorption type and explosive bolt type load release devices mentioned above. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an ultra-deep load release device and an underwater vehicle that releases the load through the cooperation of mechanical structures, eliminating the need for prolonged energy and program supply, reducing noise and improving safety, thereby enhancing the reliability and stealth of the load release process.

[0005] To achieve the above objectives, this invention provides an ultra-deep ballast jettisoning device, comprising: a base, the base being hollow, with its top for connection to an underwater vehicle and its bottom for connection to a cover plate; the cover plate being disposed within the hollow cavity of the base, its bottom connected to a wedge block seat, and having a through hole axially formed in its center; a limiting seat, the limiting seat being disposed within the through hole of the cover plate, having an opening at the top, a wedge surface at the bottom, and limiting holes on its side walls, the limiting holes being used to mount limiting components; and an electromagnet, the electromagnet being disposed within the hollow cavity of the base, its top extending through the base and electrically connected to a control assembly. The bottom is provided with a limiting boss, which is inserted into the top opening of the limiting seat and together with the cover plate, it is used to lock the limiting component; the load has a mounting hole to accommodate the wedge block seat, the mounting hole has a mounting boss, and an elastic element is sleeved on the outside of the mounting boss; one end of the elastic element contacts the bottom surface of the wedge block seat, and the other end contacts the bottom surface of the mounting hole; at least two wedges, each wedge having one end with a wedge surface that passes through the side wall of the wedge block seat and engages with the wedge surface at the bottom of the limiting seat for locking, and the other end is locked into the load.

[0006] Further optionally, the electromagnet has a first buffer pad at its top and a second buffer pad at its bottom.

[0007] Alternatively, four wedges are provided, which are evenly distributed circumferentially on the wedge seat.

[0008] Alternatively, the limiting seat may be provided with four mounting holes evenly spaced around its circumference.

[0009] Alternatively, the limiting element may be a steel ball.

[0010] Alternatively, the elastic element may be a spring, which is compressed in the mounting hole by the wedge block seat.

[0011] Further optionally, each wedge has a positioning groove at its bottom; each wedge corresponds to a positioning element, which passes through the positioning groove from the bottom of the wedge seat.

[0012] Alternatively, the positioning element may be a countersunk screw.

[0013] Alternatively, the cover plate and the wedge block seat are connected by screws.

[0014] On the other hand, the present invention also provides an underwater vehicle including the aforementioned ultra-deep ballast jettisoning device.

[0015] The above technical solution has the following beneficial effects: The embodiments of the present invention utilize the action of an electromagnet to release the limiting component under the action of the elastic component and the negative buoyancy of the load to achieve separation and load release. It does not require a long-term energy or program supply, and does not make noise during load release, greatly enhancing safety and concealment. The device converts the gravity of the load into the surface friction force of the electromagnet limiting boss through the wedge surface and limiting structure, which can achieve a gradual reduction of the force. The wedge surface angle can be designed according to different load weight requirements to achieve different electromagnet action power designs. Moreover, the structure is simple, easy to install and disassemble, and very simple to use and maintain. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the problems of existing ballast jetting devices requiring prolonged energy and program supply, or exhibiting high noise levels and safety concerns, this invention provides an ultra-deep ballast jetting device. Figure 1 This is a structural schematic diagram of the ultra-deep ejection device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the device includes: a base 1, which is hollow, with its top for connection to an underwater vehicle and its bottom for connection to a cover plate 2; the cover plate 2 is located in the hollow cavity of the base 1, with its bottom connected to a wedge block seat 12, and a through hole in the middle along the axial direction; a limiting seat 10, which is located in the through hole of the cover plate 2, with an opening at the top, a wedge surface at the bottom, and limiting holes on its side walls for mounting limiting components 9; and an electromagnet 5, which is located in the hollow cavity of the base 1, with its top extending out of the base 1 for electrical connection to a control component, and a limiting hole at its bottom. A boss, a limiting boss, is inserted into the top opening of the limiting seat 10 and together with the cover plate 2, clamps the limiting member 9; a load 11, the load 11 has a clamping hole to accommodate the wedge block seat 12, the clamping hole has a clamping boss, and an elastic member 3 is sleeved on the outside of the clamping boss; one end of the elastic member 3 contacts the bottom surface of the wedge block seat 12, and the other end contacts the bottom surface of the clamping hole; at least two wedges 4, each wedge 4 has one end with a wedge surface that passes through the side wall of the wedge block seat 12 and engages with the wedge surface at the bottom of the limiting seat 10 for clamping, and the other end is clamped into the load 11.

[0021] like Figure 1 As shown, the base 1 is cylindrical in shape, with folded edges extending outwards at both the top and bottom ends. The top folded edge has multiple connection holes for connecting with the underwater vehicle; the bottom folded edge is connected to the cover plate 2.

[0022] The cover plate 2 is located in the hollow cavity of the base 1, with an axial through hole in the middle and a folded edge extending outward from the bottom. The folded edge is fixedly connected to the wedge block seat 12.

[0023] The base 1 has an opening at the bottom, and an electromagnet 5 is installed in the hollow inner cavity. The top part of the electromagnet 5 protrudes from the top of the base 1 and is connected to the control component via a cable 8. A limiting boss is provided at the bottom, which is inserted into the top opening of the limiting seat 10 provided in the middle of the cover plate 2. The outer wall of the limiting boss and the inner wall of the through hole in the middle of the cover plate 2 together press against the limiting member 9 on the side wall of the limiting seat 10, and the electromagnet 5 is prevented from falling out by friction.

[0024] The bottom wedge surface of the limiting seat 10 mates with multiple wedge blocks 4 to complete the mounting. The wedge block seat has multiple radial mounting holes for mounting the wedge blocks. The wedge block 4 is located in the wedge block seat 12, with one end mates with the inclined surface at the bottom of the limiting seat, and the other end is mounted into the load 11.

[0025] As an optional implementation, the wedge 4 and the load 11 are also fixed by wedge surface engagement.

[0026] The wedge block seat 12 is connected to the mounting hole of the load 11 via the elastic element 3.

[0027] As an optional implementation, the two ends of the elastic element are in contact with the bottom surface of the wedge block seat and the bottom surface of the mounting hole, respectively; the two ends of the elastic element can also be connected to the bottom surface of the wedge block seat and the bottom surface of the mounting hole, respectively.

[0028] When load shedding is required, the control component sends an action signal to the electromagnet 5. The electromagnet 5 moves upward, releasing the limit of the limiting member 9. Under the thrust of the elastic member 3 and the action of load shedding, the limiting member 9 moves inward, the limiting seat 10 moves upward, and the wedge block 4 slides radially inward, releasing the limit on the load 11, thereby completing the load shedding.

[0029] As an optional implementation, the top of the electromagnet 5 is provided with a first buffer pad 7; the bottom of the electromagnet 5 is provided with a second buffer pad.

[0030] A buffer pad is set at each end of the electromagnet 5 to reduce the impact force when the electromagnet 5 is activated.

[0031] It is worth noting that the shape of the second buffer pad located at the bottom of the electromagnet 5 should be adapted to the shape of the cover plate to avoid obstructing the insertion of the limiting boss of the electromagnet 5 into the limiting seat. The first buffer pad located at the top of the electromagnet 5 should not obstruct the portion of the electromagnet protruding from the top of the base.

[0032] As an optional implementation, four wedges 4 are provided, and the four wedges 4 are evenly distributed around the wedge seat 12.

[0033] To improve the reliability of the fixation, in this embodiment, four wedges 4 are evenly arranged around the wedge seat 12. The four wedges 4 together clamp the load 11 and clamp the limit seat 10.

[0034] As an optional implementation, the limiting seat 10 has four mounting holes evenly distributed around its circumference.

[0035] To improve the reliability of limiting the electromagnet 5, this embodiment has four mounting holes evenly opened around the circumference of the limiting seat 10, and a limiting member 9 is provided in each mounting hole. The four limiting members 9 together limit the electromagnet 5.

[0036] As an optional implementation, the limiting member 9 is a steel ball.

[0037] After the load is released, the steel ball falls back into the limit seat, ensuring that the steel ball will not come out of the device.

[0038] As an alternative implementation, the elastic element 3 is a spring, which is compressed in the mounting hole by the wedge block seat 12.

[0039] The elastic element 3 is preferably a spring. When not under load, the spring is in a compressed state to provide sufficient thrust to the wedge block seat 12 when the electromagnet 5 is activated. The spring can be selected according to the actual situation to ensure that the thrust meets the requirements. The specific thrust of the spring can be calculated comprehensively based on the load weight and the friction of the limiting structure.

[0040] As an optional implementation, each wedge 4 has a positioning groove at its bottom; each wedge 4 corresponds to a positioning member, which passes through the positioning groove from the bottom of the wedge seat 12.

[0041] To prevent the wedge 4 from coming off, this embodiment provides a positioning groove at the bottom of each wedge 4, with a corresponding positioning element inserted into the positioning groove from the bottom of the wedge seat 12. The positioning groove limits the movement distance of the wedge 4. When the wedge moves to the edge of the positioning groove and contacts the positioning element, it is blocked by the positioning element. Thus, the wedge 4 will not come off the wedge seat 12 when it moves left or right.

[0042] As an optional implementation, the positioning element is a countersunk screw.

[0043] As an optional implementation, the cover plate 2 and the wedge block seat 12 are connected by screws.

[0044] The cover plate and wedge block seat, connected by screws, can be easily disassembled and installed.

[0045] During installation, first, fasten the cover plate 2 to the wedge seat 12, then insert the wedge 4 into the wedge seat 12; install the steel ball seat into the inner hole of the cover plate 2, ensuring that its wedge surface matches the wedge 4; then install the limiting member 9 into the inner hole of the steel ball seat, and sequentially install the second buffer pad, electromagnet 5, and first buffer pad 7 to the upper end of the cover plate 2, and fasten the base to the cover plate 2; install countersunk screws to the wedge 4 to ensure that it will not slip out of the wedge seat 12; install the elastic member 3 and the load 11 to the wedge surface at the other end of the wedge 4 to complete the assembly. The top end face of the base is fixed to the underwater vehicle.

[0046] This invention also provides an underwater vehicle including the aforementioned ultra-deep ballast jettisoning device.

[0047] The above technical solution has the following beneficial effects: The embodiments of the present invention utilize the action of an electromagnet to release the limiting component under the action of the elastic component and the negative buoyancy of the load to achieve separation and load release. It does not require a long-term energy or program supply, and does not make noise during load release, greatly enhancing safety and concealment. The device converts the gravity of the load into the surface friction force of the electromagnet limiting boss through the wedge surface and limiting structure, which can achieve a gradual reduction of the force. The wedge surface angle can be designed according to different load weight requirements to achieve different electromagnet action power designs. Moreover, the structure is simple, easy to install and disassemble, and very simple to use and maintain.
