Description

Technical Field

[0001] This invention belongs to the field of unmanned vessel technology, and particularly relates to a sealed cabin structure for an unmanned vessel. Background Technology

[0002] Unmanned surface vessels (USVs) are a type of surface robot that navigates autonomously using satellite positioning, sensors, and intelligent systems without human intervention. They possess autonomous navigation, obstacle avoidance, remote control, and mission execution capabilities, and are widely used in fields such as environmental monitoring, marine scientific research, security patrol, emergency rescue, resource exploration, and military applications. Existing USVs typically consist of five core components: hull structure, power system, navigation and control system, perception and communication system, and mission payload system. These systems work together to achieve autonomous navigation, environmental perception, and mission execution.

[0003] In the overall structure of an unmanned surface vessel (USV), the sealed cabin plays a crucial role. It is mainly used to house the various components required for the operation of the USV and to provide these components with a relatively independent and safe operating environment. To achieve this function, the sealed cabin adopts the design concept of protecting each piece of equipment individually. Each piece of equipment is placed in a specific area and does not interfere with each other, thereby ensuring that each piece of equipment can work stably and reliably in complex and ever-changing navigation environments.

[0004] Due to the need to balance protective performance and structural strength, sealed cabins are usually designed to be very compact, with extremely small internal spaces. When unmanned vessels malfunction and require repair, the cramped internal space is simply not large enough to accommodate maintenance personnel. They can only rely on limited external observation and testing methods to make a preliminary judgment on the location and cause of the malfunction, making the repair work extremely cumbersome. In addition, maintenance personnel need to disassemble the sealed cabin to access these core components for repair or replacement, which is quite inconvenient. Summary of the Invention

[0005] This invention provides a sealed cabin structure for unmanned vessels, aiming to solve the problems mentioned in the background art, such as the compact design of existing sealed cabins, the small internal space, the difficulty for maintenance personnel to enter and operate, and the need to disassemble the cabin for the maintenance of core components (such as the main control computer and battery pack), which is time-consuming and labor-intensive.

[0006] To address the aforementioned problems, the present invention provides an unmanned surface vessel (USV) sealed cabin structure, comprising: a hull; power boxes mounted on both sides of the hull for supporting the hull, the power boxes containing a compartment for accommodating the USV's mechanical components; propeller cylinders fixed to both sides of the power boxes for propelling the hull; a drive structure disposed within the compartments for driving the propellers to rotate; and an opening on the top of the power boxes for providing a maintenance passage, the top of the power boxes being provided with a protective structure for closing the opening.

[0007] Preferably, the drive structure includes an adjusting cylinder rotatably mounted inside the cabin, two extension blocks movably mounted inside the adjusting cylinder and extending outside the adjusting cylinder, a transmission structure disposed between the extension blocks and the blade cylinder for transmitting power, an engine fixed inside the cabin, first sprockets respectively mounted on the engine and the adjusting cylinder, and a first chain sleeved outside the first sprockets for transmission.

[0008] Preferably, the transmission structure includes a connecting shaft fixed to the two extension blocks respectively, a limiting block fixed to the connecting shaft, a transmission shaft rotatably mounted in the cabin via a fixing plate, a limiting cylinder fixed to the transmission shaft and sleeved outside the limiting block for transmission, and an adjustment mechanism disposed in the cabin for adjusting the connection state of the two limiting blocks and the two limiting cylinders to adjust the hull's heading.

[0009] Preferably, the adjustment mechanism includes a mounting plate fixed inside the cabin, a first hydraulic rod fixed on the mounting plate, a connecting block mounted on the output rod of the first hydraulic rod, a connecting frame fixed on the connecting block, and an adjustment block rotatably sleeved outside the connecting shaft and connected to the connecting frame, wherein the adjustment block is slidably mounted inside the cabin.

[0010] Preferably, the protective structure includes a support plate hinged to the power box, a second hydraulic rod fixed to the support plate, a baffle mounted on the output rod of the second hydraulic rod, and a sealing gasket fixed to the bottom of the baffle and in contact with the top of the power box for waterproofing. The power box is provided with a limiting mechanism for stabilizing the angle of the support plate.

[0011] Preferably, the limiting structure includes a first clamping plate and a second clamping plate fixed to the power box and the support plate respectively, and a limiting plate slidably installed in the power box and extending into the first clamping plate and the second clamping plate, wherein a limiting member for stabilizing the limiting plate is installed on the first clamping plate.

[0012] Preferably, the limiting member includes a cylinder mounted on the first clamping plate, a spring fixed inside the cylinder, an iron block mounted on the spring, and a clamping block mounted on the iron block. The limiting plate is provided with a slot for accommodating the clamping block, and the spring is provided with a limiting telescopic rod for limiting the extension and retraction path of the spring.

[0013] Preferably, the cabin is equipped with a water immersion sensor for detecting water leakage, and a water pump assembly for assisting in the discharge of accumulated liquid is installed in the cabin. The discharge end of the water pump assembly is equipped with a drain pipe extending to the outside of the power box, and the drain pipe is equipped with a one-way valve for preventing backflow.

[0014] Preferably, the power box is provided with a slide groove, and a guide block connected to the limiting plate is slidably installed in the slide groove. The slide groove and the guide block are used to limit the movement path of the limiting plate. A handle for providing an operating grip point is installed on the top of the support plate.

[0015] Preferably, two threaded rods are rotatably mounted on the hull, and the same counterweight for adjusting the balance of the hull is threaded onto the outside of both threaded rods. A second sprocket is fixed on each of the two threaded rods, and a second chain for transmission is sleeved on the second sprocket. A motor for driving the threaded rods to rotate is mounted on the hull.

[0016] Compared with related technologies, the unmanned vessel sealed cabin structure provided by this invention has the following beneficial effects: Compared with existing technologies, the unmanned vessel's enclosed cabin structure provided by this solution centrally stores mechanical components in a power box, making the structure compact. It eliminates the need for separate small enclosed cabins to protect different components, thus facilitating management and reducing maintenance difficulty. The propellers are driven to rotate by the propeller tubes on both sides of the power box in conjunction with the drive structure inside the cabin, reducing the space requirements for adjusting the hull's course and increasing the hull's flexibility.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a sealed cabin structure for an unmanned surface vessel, such as... Figure 1-10As shown, the unmanned surface vessel (USV) sealed cabin structure includes: a hull 1; a power box 2 installed on both sides of the hull 1 to support the hull 1, the power box 2 having a compartment for accommodating the USV's mechanical components; propeller cylinders 10 fixed on both sides of the power box 2 for propelling the hull 1; a drive structure disposed within the compartment for driving the propeller blades to rotate; and an opening on the top of the power box 2 for providing a maintenance passage, the top of the power box 2 having a protective structure for closing the opening.

[0022] In this embodiment, the hull 1 provides a basic support structure for the unmanned surface vessel (USV). Power boxes 2 are installed on both sides of the hull 1, each containing a compartment for mechanical components. This centralized storage of components facilitates management and makes the structure more compact, eliminating the need for separate sealed compartments for individual structures. The centralized structure within a single empty compartment reduces access difficulty and eliminates the need to disassemble and open different sealed compartments during maintenance, effectively reducing maintenance complexity. Propeller cylinders 10 are fixed to both sides of the power box 2, working in conjunction with the drive structure within the compartment to rotate the propellers, thus propelling the hull 1 and ensuring the USV's power output and navigation capabilities. An opening at the top of the power box 2 provides a passage for maintenance personnel to enter the compartment for equipment maintenance, allowing for some level of repair work even in a limited space. A protective structure at the top of the power box 2, used to close the opening, protects the equipment inside the compartment from external damage and ensures the compartment's airtightness when not under maintenance, extending the equipment's lifespan.

[0023] In a further preferred embodiment of the present invention, the drive structure includes an adjusting cylinder 3 rotatably mounted inside the cabin, two extension blocks 4 movably mounted inside the adjusting cylinder 3 and extending outside the adjusting cylinder 3, a transmission structure disposed between the extension blocks 4 and the blade cylinder 10 for transmitting power, an engine 11 fixed inside the cabin, first sprockets 12 respectively mounted on the engine 11 and the adjusting cylinder 3, and a first chain 13 sleeved outside the first sprockets 12 for transmission.

[0024] In this embodiment, an adjusting cylinder 3, rotatably mounted inside the cabin, serves as the core rotating carrier for the entire drive structure. Two extension blocks 4, movably installed inside the adjusting cylinder 3 and extending outwards, provide flexible adjustment. The position of the extension blocks 4 can be adjusted according to actual needs, thereby changing the power transmission state. Through the transmission structure set between the extension blocks 4 and the blade cylinder 10, the power of the adjusting cylinder 3 is stably transmitted to the blade cylinder 10 to drive the blade rotation, thus ensuring the power output of the unmanned vessel. An engine 11 is set inside the cabin, providing a power source. By installing first sprockets 12 on the engine 11 and adjusting cylinder 3 respectively, and fitting first chains 13, stable transmission is achieved. By setting a single power source and cooperating with the transmission structure to adjust and drive different blade cylinders 10, repeated inspections are not required during equipment maintenance, reducing maintenance difficulty.

[0025] In a further preferred embodiment of the present invention, the transmission structure includes a connecting shaft 5 respectively fixed on the two extension blocks 4, a limiting block 6 fixed on the connecting shaft 5, a transmission shaft 7 rotatably mounted in the cabin via a fixing plate 9, a limiting cylinder 8 fixed on the transmission shaft 7 and sleeved outside the limiting block 6 for transmission, and an adjustment mechanism disposed in the cabin for adjusting the connection state of the two limiting blocks 6 and the two limiting cylinders 8 to adjust the heading of the hull 1.

[0026] In this embodiment, by fixing connecting shafts 5 to the two extension blocks 4 respectively, a basic connecting component is provided for the subsequent transmission structure, giving the power transmission an initial connection point. By fixing limiting blocks 6 to the connecting shafts 5, the transmission position and range are defined, providing a basis for the transmission with limiting cylinders 8. By rotatably installing the transmission shaft 7 in the cabin, a stable support and rotational environment are provided for the transmission shaft 7, ensuring that the transmission shaft 7 can operate normally. By fixing limiting cylinders 8, which can be sleeved on the limiting blocks 6, to the transmission shaft 7, when the limiting blocks 6 and the limiting cylinders 8 cooperate, the purpose of transmitting power is achieved, transmitting the power of the extension blocks 4 to the transmission shaft 7. By setting an adjustment mechanism to adjust the connection state of the two limiting blocks 6 and the two limiting cylinders 8, the power transmission path can be flexibly changed, thereby adjusting the heading of the hull 1, enhancing the maneuverability and flexibility of the unmanned vessel, allowing the unmanned vessel to adjust its navigation direction according to different environments and mission requirements, and improving the adaptability and practicality of the unmanned vessel in complex waters.

[0027] In a further preferred embodiment of the present invention, the adjustment mechanism includes a mounting plate 17 fixed in the cabin, a first hydraulic rod 18 fixed on the mounting plate 17, a connecting block 16 mounted on the output rod of the first hydraulic rod 18, a connecting frame 15 fixed on the connecting block 16, and an adjustment block 14 rotatably sleeved outside the connecting shaft 5 and connected to the connecting frame 15, wherein the adjustment block 14 is slidably mounted in the cabin.

[0028] In this embodiment, by fixing the mounting plate 17 inside the cabin, a stable mounting base is provided for the first hydraulic rod 18, ensuring the stability of the first hydraulic rod 18 and thus ensuring the stability of the entire adjustment mechanism. By fixing the first hydraulic rod 18 to the mounting plate 17, the extension and retraction characteristics of its output rod are used to provide adjustment power. By installing the connecting block 16 on the output rod of the first hydraulic rod 18, a transitional function of connecting and transmitting power is provided. By fixing the connecting frame 15 on the connecting block 16, the power transmission range is further expanded. By setting an adjustment block 14 that is rotatably sleeved outside the connecting shaft 5 and connected to the connecting frame 15, and the adjustment block 14 is slidably installed inside the cabin, when the first hydraulic rod 18 moves, it can drive the adjustment block 14 to slide, thereby changing the connection state of the limit block 6 and the limit cylinder 8, so that the direction of travel of the hull 1 can be adjusted, enhancing the maneuverability of the unmanned vessel.

[0029] In a further preferred embodiment of the present invention, the protective structure includes a support plate 20 hinged to the power box 2 via a hinge 19, a second hydraulic rod 21 fixed to the support plate 20, a baffle 22 mounted on the output rod of the second hydraulic rod 21, and a sealing gasket 23 fixed to the bottom of the baffle 22 and capable of contacting the top of the power box 2 for waterproofing. The power box 2 is provided with a limiting mechanism for stabilizing the angle of the support plate 20.

[0030] In this embodiment, the support plate 20 is hinged to the power box 2 via hinge 19, allowing the support plate 20 to rotate flexibly. This provides a basis for opening and closing the opening at the top of the power box 2, facilitating maintenance personnel to inspect and repair the equipment inside the cabin. By fixing the second hydraulic rod 21 to the support plate 20, the extension and retraction characteristics of its output rod provide stable power and control the movement of the baffle 22. The baffle 22, installed on the output rod of the second hydraulic rod 21, can move up and down under the action of the second hydraulic rod 21, achieving control over the opening and closing, ensuring the airtightness of the cabin. The sealing gasket 23, fixed to the bottom of the baffle 22 and in contact with the top of the power box 2, provides good waterproofing, effectively preventing external moisture from entering the cabin and avoiding damage to the equipment due to moisture, thus extending the service life of the equipment. The limiting mechanism set on the power box 2 stabilizes the angle of the support plate 20, preventing it from accidentally opening due to shaking during the unmanned vessel's navigation, further enhancing the reliability and stability of the protective structure.

[0031] In a further preferred embodiment of the present invention, the limiting structure includes a first locking plate 24 and a second locking plate 25 respectively fixed on the power box 2 and the support plate 20, a limiting plate 27 slidably installed on the power box 2 and capable of extending into the first locking plate 24 and the second locking plate 25, and a limiting member 26 for stabilizing the limiting plate 27 is installed on the first locking plate 24.

[0032] In this embodiment, by fixing the first locking plate 24 and the second locking plate 25 to the power box 2 and the support plate 20 respectively, a locking structure is provided for the insertion of the limiting plate 27, which facilitates a stable connection between the support plate 20 and the power box 2. The limiting plate 27, which is slidably installed on the power box 2 and can extend into the first locking plate 24 and the second locking plate 25, plays a limiting role. When the limiting plate 27 is inserted between the two locking plates, it can effectively prevent the support plate 20 from rotating, prevent the protective structure from being opened accidentally, and ensure the airtightness of the cabin and the safety of the internal equipment. By installing the limiting member 26 on the first locking plate 24 to stabilize the limiting plate 27, the stability of the limiting plate 27 is further enhanced, preventing it from shifting or falling off due to shaking during the unmanned vessel's navigation, ensuring that the limiting function is continuously effective, which is convenient for maintenance personnel to operate and can also ensure the stability of the protective structure when the unmanned vessel is navigating in complex waters.

[0033] In a further preferred embodiment of the present invention, the limiting member 26 includes a cylindrical body 35 mounted on the first clamping plate 24, a spring 36 fixed inside the cylindrical body 35, an iron block 38 mounted on the spring 36, and a clamping block 39 mounted on the iron block 38. The limiting plate 27 is provided with a slot for accommodating the clamping block 39, and the spring 36 is provided with a limiting telescopic rod 37 for limiting the extension and retraction path of the spring 36.

[0034] In this embodiment, by installing a cylinder 35 on the first locking plate 24, installation space is provided for internal components such as the spring 36. The spring 36, fixed inside the cylinder 35, utilizes its elastic properties to provide elastic force, which powers the extension and retraction of the locking block 39, allowing the locking block 39 to flexibly enter and exit the locking slot. The iron block 38 installed on the spring 36 serves as a connecting component, transmitting the elastic force of the spring 36 to the locking block 39, while increasing the weight and stability of the locking block 39. At the same time, the locking block 39 can be unlocked by magnetically attracting the iron block 38, reducing the difficulty of operation. The locking block 39 installed on the iron block 38 cooperates with the locking slot on the limiting plate 27. When the locking block 39 extends into the locking slot, it stabilizes the limiting plate 27, preventing it from moving arbitrarily. The limiting telescopic rod 37 limits the extension and retraction path of the spring 36, preventing the spring 36 from shifting during extension and retraction, and ensuring the stability and reliability of the spring 36's operation.

[0035] In a further preferred embodiment of the present invention, a water immersion sensor 40 for detecting water leakage is provided in the cabin, and a water pump group 41 for assisting in the output of accumulated liquid is installed in the cabin. The discharge end of the water pump group 41 is equipped with a discharge pipe extending to the outside of the power box 2, and a one-way valve for preventing backflow is provided on the discharge pipe.

[0036] In this embodiment, by installing a water immersion sensor 40 inside the cabin, the leakage status inside the cabin can be detected in real time. Once water seeps in, a signal can be sent in time, allowing maintenance personnel to know immediately that an abnormality has occurred in the cabin, buying time for subsequent handling and playing a timely early warning role. This effectively prevents the equipment damage caused by water leakage from worsening. By installing a water pump set 41 inside the cabin, when the water immersion sensor 40 detects water leakage, the water pump set 41 can be quickly started to pump out the liquid accumulated in the cabin, playing a rapid drainage function, preventing water accumulation from corroding the components inside the cabin, ensuring the normal operation of the equipment, and extending the service life of the equipment. By installing a drain pipe extending to the outside of the power box 2 at the drain end of the water pump set 41, and the drain pipe is equipped with a one-way valve, the pumped liquid can be smoothly discharged outside the power box 2. At the same time, the one-way valve can effectively prevent external liquid from flowing back into the cabin through the drain pipe, avoiding the risk of secondary water accumulation and further enhancing the waterproof performance of the cabin.

[0037] In a further preferred embodiment of the present invention, the power box 2 is provided with a slide groove 28, and a guide block 29 connected to the limiting plate 27 is slidably installed in the slide groove 28. The slide groove 28 and the guide block 29 are used to limit the movement path of the limiting plate 27. A handle 30 for providing an operating grip point is installed on the top of the support plate 20.

[0038] In this embodiment, by setting a slide groove 28 on the power box 2 and sliding a guide block 29 connected to the limiting plate 27 within the slide groove 28, the movement path of the limiting plate 27 is limited. The cooperation between the slide groove 28 and the guide block 29 ensures that the limiting plate 27 can only slide stably in a specific direction, preventing it from deviating or getting stuck during movement. This ensures that the limiting plate 27 can be smoothly inserted or pulled out between the first locking plate 24 and the second locking plate 25, thereby achieving a reliable limiting function. By installing a handle 30 on the top of the support plate 20, a convenient gripping point is provided for the operator. When it is necessary to open or close the support plate 20, the operator can easily apply force to the support plate 20 by holding the handle 30, causing it to rotate around the hinge 19, thus conveniently and quickly completing the opening and closing operation of the protective structure. This not only improves the operating efficiency but also reduces the operating difficulty. Especially in environments where space is relatively compact or operation is inconvenient, flipping the support plate 20 can effectively reduce the obstruction of the opening, making it convenient for personnel to enter the sealed chamber to maintain the internal structure.

[0039] In a further preferred embodiment of the present invention, two threaded rods 31 are rotatably mounted on the hull 1. Both threaded rods 31 are threaded with the same counterweight 32 for adjusting the balance of the hull 1. A second sprocket 33 is fixed on both threaded rods 31. A second chain 34 for transmission is sleeved on the second sprocket 33. A motor for driving the threaded rods 31 to rotate is mounted on the hull 1.

[0040] In this embodiment, by rotatably installing two threaded rods 31 on the hull 1 and threading a counterweight 32 onto the two threaded rods 31, an operable basis is provided for adjusting the balance of the hull 1. When the threaded rods 31 rotate, the counterweight 32 can move along the axial direction of the threaded rods 31, thereby changing its position on the hull 1 and flexibly adjusting the center of gravity distribution of the hull 1. By fixing a second sprocket 33 on the two threaded rods 31 and sleeved with a second chain 34 on the second sprocket 33, the two threaded rods 31 can rotate synchronously using chain drive, ensuring the stability and consistency of the counterweight 32 during movement and avoiding the problem of the counterweight 32 jamming or tilting due to asynchronous rotation of the two threaded rods 31. A motor is provided to power the rotation of the threaded rods 31. By controlling the operation of the motor, the threaded rods 31 can be driven to rotate, thereby adjusting the position of the counterweight 32. This allows the hull 1 to quickly and effectively adjust its balance according to different navigation environments and load conditions, improving the navigation stability and safety of the unmanned vessel.

[0041] It is worth noting that the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods. The hull 1 is also equipped with a navigation and control system, a sensing and communication system, and a mission payload system.

[0042] The working principle of the continuous tofu whey efficient collection device and method provided by this invention is as follows: Before use, ensure all components are correctly installed and securely connected. Turn on the motor (using a Siemens 1FT7 servo motor as an example) to drive the threaded rod 31 to rotate. This, through the second sprocket 33 and the second chain 34, causes the two threaded rods 31 to rotate synchronously, moving the counterweight 32 to a suitable position to adjust the balance of the hull 1. Turn on the engine 11 (using a CSE-WinGD series as an example). The engine 11 drives the first sprocket 12 to rotate, which in turn drives the adjusting cylinder 3 to rotate through the first chain 13. Adjust the position of the extension block 4 within the adjusting cylinder 3 according to actual needs. The power of the adjusting cylinder 3 is transmitted to the propeller cylinder 10 via the connecting shaft 5, limit block 6, limit cylinder 8, and drive shaft 7, driving the propeller blades to rotate and propel the hull 1. When it is necessary to adjust the heading of the hull 1, activate the first hydraulic rod 18 (using an ATOS hydraulic cylinder CK40 as an example). Its output rod extends and retracts, moving the connecting block 16 and the connecting frame 15, which in turn causes the adjusting block 14 to slide. By changing the connection state of the limiting block 6 and the limiting cylinder 8, when it is necessary to maintain the equipment inside the cabin, the output rod of the second hydraulic rod 21 (taking the ATOS hydraulic cylinder CK40 as an example) is first retracted. The iron block 38 is attracted by the magnet, causing the locking block 39 to exit from the locking slot of the limiting plate 27. The limiting plate 27 is moved to release the limitation on the support plate 20. The handle 30 is held and rotated around the hinge 19 to open the opening. The maintenance personnel enter the cabin for maintenance. After the maintenance is completed, the support plate 20 is closed. The limiting plate 27 is moved and inserted between the first locking plate 24 and the second locking plate 25. The locking block 39 extends into the locking slot under the action of the spring 36 to stabilize the limiting plate 27. During navigation, the water immersion sensor 40 (taking XW-DC-01A as an example) detects the water leakage status of the cabin in real time. If water leakage is detected, the water pump group 41 (composed of a water pump and drive components, taking the IS series as an example) is started to discharge the accumulated liquid out of the power box 2 through the drain pipe. At the same time, the unmanned vessel returns to port.

[0043] In summary, compared with related technologies, this device has a compact structure by centrally storing mechanical parts in the power box 2. It does not require separate small, enclosed compartments to protect different components, thus facilitating management and reducing maintenance difficulty. The propeller cylinders 10 on both sides of the power box 2 work in conjunction with the drive structure inside the compartment to drive the propeller blades to rotate, reducing the space requirements for adjusting the course of the hull 1 and increasing the flexibility of the hull 1.

[0044] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
