Description

[0002] In recent years, with the rapid development of unmanned equipment in the fields of ocean exploration, intelligent cruise, remote supply and the like, the collaborative operation platform integrating unmanned aerial vehicles and unmanned ships has gradually become an important direction of the development of intelligent ocean equipment. In such a system, in order to realize reliable recovery and safe storage of the unmanned aerial vehicle, the unmanned aerial vehicle is often accommodated into the ship body through the hatch structure, and the opening part of the ship body is effectively sealed to ensure that the equipment in the cabin is not invaded by external water in the complex marine environment.

[0003] However, the existing technology uses a semicircular door body, which is closed by rotating the door body through hydraulic pressure. A sawtooth-shaped sealing groove is arranged on the circumference of the door body, and a seal is formed by pressure after closing to prevent leakage. However, in long-term marine deployment, the sealing ring is frequently affected by alternating stress due to the frequent opening and closing of the hatch, which affects the service life of the sealing ring surface coating and further affects the service life of the sealing ring surface.

[0004] In addition, the existing unmanned aerial vehicle docking platform separates the take-off and landing structure and the sealing structure, which has low system integration, occupies a large space, and is not conducive to miniaturization and modular deployment. For unmanned ships, there is a lack of an independently controllable diving adjustment mechanism, so that when a storm comes, it needs to return to port or rely on its own structural strength to resist, which limits its multi-scenario adaptability in complex tasks.

[0045] In order to make those skilled in the art better understand the present application, the present application will be further described in detail below in conjunction with the specific embodiments and drawings.

[0046] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions about the present application, but these terms can be changed according to the intention of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms can be selected by the applicant, and in this case, the detailed meanings thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present application.

[0047] Embodiment 1, refer to Figures 1-4This embodiment provides a hatch sealing mechanism, including a first mating surface 100 on which a sealing surface 101 is provided; and a second mating surface 200 on which a sealing groove 201 is provided. A guide surface 202 is provided on the side opposite to the sealing groove 201 and the third sealing surface 101c. The guide surface 202 and the third sealing surface 101c are arranged in an expanded structure. A sealing element 300 is disposed in the sealing groove 201.

[0048] The sealing element 300 includes a sealing ring 301, one end of which faces away from the groove 301a and is adapted to the guide surface 202 and the third sealing surface 101c, and an expanded groove 301a is provided on its outer side; an O-ring 302 is fitted onto the groove 301a; the sealing surface 101 includes a first sealing surface 101a, one end of which is provided with a second sealing surface 101b, which abuts against the outer circumference of the sealing ring 301, and the other end of which is provided with a third sealing surface 101c;

[0049] When the first mating surface 100 abuts against the second mating surface 200, the O-ring 302 abuts against the first sealing surface 101a.

[0050] like Figure 1 As shown, in order to achieve efficient sealing and adaptive ballast function of the hatch in the deep sea environment, this embodiment provides a hatch sealing mechanism with a multi-level sealing cooperative structure. The sealing mechanism mainly includes a first mating surface 100, a second mating surface 200, and a sealing element 300 disposed between the two.

[0051] The first mating surface 100 is an installation surface located on one side of the cabin. On the side facing the second mating surface 200, it has three continuously transitioning sealing surfaces 101. These sealing surfaces 101, from the outside to the inside, sequentially form a first sealing surface 101a, a second sealing surface 101b, and a third sealing surface 101c. The first sealing surface 101a is the outermost sealing surface; the second sealing surface 101b is located inside the first sealing surface 101a and forms a seal with the outer circle of the sealing ring 301, and is not loaded during initial closure; while the third sealing surface 101c cooperates with the guide structure, providing a sealing base surface for end-sealing compensation. The three sealing surfaces are interconnected in shape, forming a progressively concave trapezoidal structure.

[0052] The second mating surface 200 is a mating surface provided on the hatch 400, and a sealing groove 201 is provided at the end facing the first mating surface 100 for accommodating the sealing element 300. Preferably, an inclined expansion guide surface 202 is also formed at the position opposite to the sealing groove 201 and the third sealing surface 101c.

[0053] The sealing element 300 is a core sealing structure arranged in the sealing groove 201, which comprises a sealing ring 301 and an O-ring 302 sleeved on one end of the sealing ring 301. The sealing ring 301 is made of an elastic material as a whole, and the outer circumference is used to contact the second sealing surface 101b; one end of the sealing ring 301 in the direction of the inflow of seawater is provided with an expanding notch 301a, and the notch 301a is preferably designed to enable the O-ring 302 to translate along the pressure of seawater, so that the pressure of seawater can act on the O-ring 302 entirely. The O-ring 302 is preferably a PTFE stop ring, which is sleeved in the notch 301a and is preloaded on the first sealing surface 101a to form an initial contact seal.

[0054] During the process of continuously closing the hatch, the O-ring 302 first forms a surface contact with the first sealing surface 101a as the second abutting surface 200 moves towards the first abutting surface 100. Due to the elasticity of the O-ring 302 and the smoothness of the first sealing surface 101a, an effective static seal can be provided in the initial closing state to prevent salt mist in the marine environment from entering. If there is no such primary sealing structure, the system will be exposed to a corrosive gas environment, which will seriously affect the integrity and reliability of the subsequent sealing surface.

[0055] Further, during the process of gradually diving of the unmanned ship, the O-ring 302 is gradually pressed into the inside of the expanding notch 301a under the action of external water pressure. During this process, because the shape of the notch 301a gradually narrows from the outside to the inside, the O-ring 302 will be laterally extruded to the two side walls of the notch 301a during the pressing process, thereby forming a radial expansion effect on the sealing ring 301, so that the inner sealing lip of the sealing ring 301 contacts the first sealing surface 101a, and the outer circumference forms a sealing contact with the second sealing surface 101b, thereby ensuring that a stable seal can be formed under different pressure levels.

[0056] As the sealing ring 301 is gradually deformed, the end thereof is guided by the guide narrowing area formed by the third sealing surface 101c and the guide surface 202. In the deep water high pressure working condition, or when the sealing ability of the second sealing surface 101b is reduced due to wear or local failure of the outer circumference of the sealing ring 301, the pressure of the O-ring 302 presses the sealing ring 301 to the side of the guide surface 202, and the structure of the guide surface 202 and the third sealing surface 101c enables the end of the sealing ring 301 to be in close contact with the third sealing surface 101c, thereby forming a final compensation seal. This structure significantly improves the redundancy and self-adaptive ability of the entire sealing system in the failure working condition.

[0057] Embodiment 2, with reference to Figures 5-7For the second embodiment of the application, which is different from the first embodiment, one end of the first sealing surface 101a is provided with a second sealing surface 101b, the second sealing surface 101b is in abutment with the outer circumference of the sealing ring 301, and the other end of the second sealing surface 101b is provided with a third sealing surface 101c; the side of the sealing groove 201 opposite to the third sealing surface 101c is provided with a guide surface 202, the guide surface 202 and the third sealing surface 101c are arranged in an expanding structure; the end of the sealing ring 301 away from the slot 301a is adapted to the guide surface 202 and the third sealing surface 101c, and the first abutment surface 100 and the second abutment surface 200 are arranged obliquely, so that the hatch door 400 can be guided during the closing process, thereby improving the abutment precision.

[0058] On the basis of the structure of the above-mentioned basic embodiment, in order to further improve the ballast response capability and sealing durability of the hatch door sealing mechanism under deep water conditions, the second sealing surface 101b is preferably arranged at one end of the first sealing surface 101a away from the seawater inflow direction. The second sealing surface 101b is arranged opposite to the outer circumference of the sealing ring 301 in the sealing element 300, and the two form a surface contact type cooperation during the closing process of the hatch door, but do not perform ballast, thereby reducing the peeling of the coating and the aging of the seal caused by repeated ballast under the condition of the open sea.

[0059] Specifically, the second sealing surface 101b is an inner ring segment arranged in the first abutment surface 100 structure, which is annular in form and forms a contact transition surface corresponding to the outer circular arc surface of the sealing ring 301. Compared with the primary sealing function of the first sealing surface 101a, the purpose of arranging the second sealing surface 101b is to establish an intermediate level of ballast sealing channel through elastic contact with the outer circumference of the sealing ring 301, as a deformation buffer zone during water pressure loading, gradually absorbing the radial pressure diffusion of the O-ring 302 after entering the expanding slot 301a.

[0060] During use, as the external seawater pressure increases, the O-ring 302 is continuously pressed into the slot 301a, and at the same time, the sealing ring 301 is expanded outward in the radial direction, and its outer circumference gradually fits the second sealing surface 101b. Since the sealing ring 301 is made of elastic material, this fitting process is not instantaneous, but is in a gradual contact state; this step-by-step loading dynamic response mode effectively avoids the problem of stress concentration and sealing failure caused by rapid compression.

[0061] Without the second sealing surface 101b, the outer circle of the sealing ring 301 will be peeled, flanged or scratched due to wear, which seriously affects the sealing effect. Through the structure arrangement, not only a middle sealing site is formed, but also a synergistic effect of stabilizing the circumferential shape of the sealing ring and delaying aging failure is achieved.

[0062] A third sealing surface 101c is arranged at the other end of the first sealing surface 101a, and a guide surface 202 is arranged at the side of the sealing groove 201 of the second abutment surface 200 opposite to the third sealing surface 101c. The third sealing surface 101c and the guide surface 202 form a tapered expansion structure together to define an end sealing channel and guide the deformation of the end of the sealing ring 301 away from the notch 301a.

[0063] Specifically, the third sealing surface 101c is the innermost sealing surface in the sealing surface structure of the first abutment surface 100, which is axially inwardly retracted and forms a certain angle with the second sealing surface 101b, and the surface is preferably arranged as an inclined surface structure, which does not bear the load of the sealing ring 301 in the initial state, to provide the last sealing contact interface. The guide surface 202 is arranged at one end of the sealing groove 201 of the second abutment surface 200, which is arranged at a corresponding angle with the third sealing surface 101c, and the two define a sealing guide surface structure with gradient convergence characteristics.

[0064] The end of the sealing ring 301 away from the notch 301a, i.e. the end away from the loading side of the O-ring 302, does not directly participate in the primary or middle sealing in the free state. Only when the sealing ring 301 is axially deformed and pushed along the guide channel under the driving force of the O-ring 302 continuously pressed into the notch 301a, does the end produce sufficient pressure sealing with the third sealing surface 101c and the guide surface 202. In this process, the guide surface 202 plays a role in correcting the deformation direction of the end of the sealing ring 301.

[0065] In particular, the angle between the third sealing surface 101c and the guide surface 202 forms a sealing area that can be used as a final compensation sealing path when the O-ring 302 is insufficiently loaded or the outer circumference of the sealing ring 301 is aged, worn, deformed and fails, thereby ensuring that the hatch system still has residual sealing ability in a non-ideal state. In essence, a safety redundancy layer is constructed in the sealing mechanism to ensure reliable closure of the hatch 4 under various working conditions.

[0066] Embodiment 3, with reference to Figure 8 and 9 This is the third embodiment of the present application, which is different from the second embodiment in that it comprises a hatch sealing mechanism, and further comprises a hatch 400, the second abutment surface 200 being arranged at one side of the hatch 400; a boat body 600, the first abutment surface 100 being arranged at the side opposite to the hatch 400;

[0067] A plurality of circumferentially arranged fixed butt teeth 103 are arranged at the circumferential position of the hull 600, and a plurality of circumferentially arranged movable butt teeth 203 are arranged at the circumferential position of the hatch 400; the fixed butt teeth 103 are matched with the movable butt teeth 203, the tooth shape of the fixed butt teeth 103 is arranged in a trapezoidal structure, and the trapezoidal structure is arranged in a narrow-top-wide-bottom manner, and the inner surface of the hatch 400 forms a landing apron 401;

[0068] The driving assembly 500 is fixedly connected to the inner surface of the hatch 400 at one end; the rear part of the hull 600 is rotationally connected with the hatch 400, and the other end of the driving assembly 500 is fixedly connected with the inner wall of the hull 600; the inside of the hull 600 is provided with a recovery cabin 601 and a storage cabin 602, the inside of the storage cabin 602 is provided with a guide rail 603, the front side of the hull 600 is provided with a fairing 604, and the fairing 604 is in a conical structure; the two sides of the hull 600 are provided with driving devices 605, and the top of the hull 600 is provided with lifting lugs 606, which are two and are fixedly connected to the two ends of the hull 600.

[0069] The hatch 400 is arranged at the opening of the tail of the hull 800, and the inner surface thereof is designed as an integrated landing apron 401, which is used for providing an operation platform for the vertical take-off and landing, sliding landing or short-time parking of the unmanned aerial vehicle. The landing apron 401 is preferably a flat and continuous arc-shaped area, which can be formed by integral casting, and is provided with an anti-skid coating, a wear-resistant covering layer or a positioning groove structure for locking a tray, so as to enhance the friction performance and structural stability, and effectively avoid the deviation and sliding of the unmanned aerial vehicle in the impact of take-off and landing or wave shaking.

[0070] In order to maximize the space utilization of the launching platform and match the streamlined structure of the hull 800, the hatch 400 has a semicircular outer contour, and the arc edge thereof is geometrically continuously connected with the outer edge of the tail of the hull 800. The arc-shaped outer shape not only reduces the hydrodynamic resistance of the hull 800 during navigation, but also improves the compression strength and deformation rigidity of the hatch 400 itself through the arc surface structure of the shell, so as to ensure the structural strength of the hatch 400 in a high-pressure water environment.

[0071] The movable butt teeth 203 of the embodiment of the present application are fixedly installed at the circumferential edge position of the hatch 400, and form a meshing sealing structure with the fixed butt teeth 103 of the rear part of the hull 800. The matching adopts an upper and lower semicircular butt joint manner, the tooth shape of the matching area is in a trapezoidal structure with a narrow-top-wide-bottom shape, when the hatch is closed, the movable butt teeth 203 realize preliminary alignment with the help of the guide surface 202, then complete sealing and pressing, and finally realize gas-liquid blocking; and in the open state of the hatch, the unmanned aerial vehicle can complete the launching and recovery actions on the completely open landing apron 401.

[0072] The opening and closing of the hatch 400 is controlled by the drive assembly 500 arranged on both sides of the inner surface of the hatch 400. The drive assembly 500 can be an electric push rod or a hydraulic cylinder mechanism, one end of which is fixed to the internal structure of the boat body 800, and the other end is connected with the side wall of the hatch 400. During the opening process, the drive assembly 500 pushes the hatch 400 outward, rotates it around the tail shaft to open it, and releases the semicircular parking platform; during the closing process, the drive assembly 500 reversely drives the hatch 400 to rotate back to the original position, and pushes the movable abutting teeth 203 to precisely engage with the fixed abutting teeth 103, and finally completes the compression sealing of the hatch 400 with the help of external water pressure and its own tension.

[0073] Further, the boat body 600 is also included. The boat body 600 is a structural body that carries the entire platform function, and the tail thereof is rotationally connected with the hatch 400 through a shaft structure or a hinge mechanism, for supporting the structural rotation path of the hatch during the opening and closing process.

[0074] The other end of the drive assembly 500 is fixedly connected to the internal frame structure of the boat body 600, so as to form a transmission closed loop therebetween. During the opening and closing of the hatch, the drive assembly 500 can provide a push-pull force to realize the orderly opening and closing of the hatch 400, and ensure the pressure loading process during the engagement process.

[0075] During use, when diving operation is needed, the water outside the boat is introduced into the cabin through the control valve cooperation, so as to increase the total weight of the boat body 600 and reduce the buoyancy, thereby realizing active diving; when floating or maintaining a specific depth is needed, the pressurized water in the cabin can be discharged through the operation of injecting compressed gas or draining water, so as to restore the buoyancy, thereby realizing the floating or depth maintaining of the boat body 600.

[0076] The boat body 600 is internally provided with two main functional cabins: a recovery cabin 601 and a storage cabin 602. The recovery cabin 601 is arranged in the upper area of the boat body 600, and serves as a temporary transition cabin for the unmanned aerial vehicle after completing the task. In order to realize the automatic introduction and attitude correction of the unmanned aerial vehicle in the cabin, the recovery cabin 601 is internally provided with an extended guide rail 603. The guide rail 603 is preferably arranged as a symmetrical linear track structure, which is used to cooperate with the pulley structure of the tray to guide the tray carrying the unmanned aerial vehicle to slide into the predetermined position in the cabin, so as to ensure the precise parking and alignment control of the unmanned aerial vehicle during recovery. If there is wave disturbance or unstable hatch closing, the guide rail 603 can also provide necessary sliding damping and lateral limiting.

[0077] The storage cabin 602 located below the recovery cabin 601 is used as a fixed storage cabin for the unmanned aerial vehicle, and is used as a front cabin for stable recovery, storage, attitude adjustment and system check before the next task after the unmanned aerial vehicle is recovered. In order to realize the vertical cabin moving action of the unmanned aerial vehicle after sliding into the recovery cabin 601 from the upper part, the inside of the storage cabin 602 is preferably provided with lifting equipment, including but not limited to an electric lifting platform, a scissor lifting mechanism or a track elevator.

[0078] The lifting equipment is installed at the bottom of the storage cabin 602. When the unmanned aerial vehicle tray slides into the recovery cabin 601 through the guide rail 603, the lifting equipment starts to rise from the bottom to recover the tray to the bottom of the recovery cabin 601, and the whole process is stable and orderly, which ensures that the unmanned aerial vehicle is not subjected to secondary impact during movement.

[0079] In order to enhance the structural safety and the environmental adaptability in the cabin, the lifting equipment is preferably provided with a position encoder and a limit sensor to realize accurate control of the lifting height and multi-point limiting; at the same time, a positioning support or a locking mechanism is arranged in the inside of the storage cabin 602 for mechanical fixation after the tray lands, so as to prevent shaking or slipping during navigation.

[0080] If the above functional partition is not set, the unmanned aerial vehicles will be in a stacked state in the cabin, which is easy to be affected by external waves, resulting in rolling, collision or structural damage; at the same time, it also causes difficulty in operation, so that the unmanned aerial vehicles cannot be reasonably considered in the deployment of recovery and release, and sometimes the front side of all unmanned aerial vehicles needs to be released before another wave of unmanned aerial vehicles can be released, which seriously affects the operation continuity and task coordination efficiency of the system.

[0081] In order to optimize the hydrodynamic performance and structural stability of the boat body 800, a fairing 604 is arranged at the front of the boat body 800, the fairing 604 is in a conical structure with a pointed end facing forward, and the conical shape guides the water flow line to envelop the boat body, reduces the front water flow impact force and flow resistance, and improves the navigation stability and control performance.

[0082] In addition, in order to ensure that the unmanned boat has independent propulsion and steering capability, drive devices 605 are arranged on both sides of the boat body 600, the devices can be electric propulsion propellers, water jet thrusters or rudder propeller composite systems, and are distributed on both sides of the middle and rear parts of the boat body 800 to form a double-sided power propulsion structure, which effectively improves the anti-interference ability of the platform and the stability of the unmanned aerial vehicle take-off and landing platform.

[0083] In order to facilitate the overall transportation, hoisting and rapid deployment of the platform, two lifting lugs 606 are arranged on the top of the boat body 600 and are fixedly connected to the front and rear ends of the boat body 600, which are made of high-strength alloy and can bear the gravity load of the whole boat during movement in the air or on the deck, and support the hoisting operation of the crane, hoisting arm and other equipment.

[0084] By structural integration design, the hull 600 is taken as a core bearing platform, and the cabin door sealing mechanism, the unmanned aerial vehicle parking platform, the ballast system and the auxiliary stabilizing assembly are integrated, so that a multifunctional operation system with complete functions and high cooperation efficiency is constructed. The system has high structural integration, can complete multiple tasks such as cabin door sealing, unmanned aerial vehicle taking-off and landing and storage, water pressure self-adaptive ballast, navigation stability control, and enhances the operation adaptability of the platform. The unmanned ship can not only perform unmanned aerial vehicle platform operation on the water surface, but also has a certain degree of short-time diving, depth avoidance or underwater hiding capability, which expands the combat adaptability and task extension of the platform in scenes such as storm avoidance, water surface to underwater cooperation and the like.

[0085] The rest of the structure is the same as that of example 2.
