Description

Technical Field

[0001] This application relates to the technical field of intelligent docks, and in particular to an intelligent dock lifting device. Background Technology

[0002] With increasing attention to the ecological environment and the development of ecological governance, the requirements for water environment monitoring, management and ecological restoration in rivers and lakes are becoming higher and higher, and the tasks are becoming more and more numerous. In order to meet the requirements of automatic water environment monitoring and intelligent management, a large number of unmanned vessels need to be used to complete related operations. At the same time, in order to reduce the workload of manual transportation and storage of unmanned vessels, it is usually accompanied by the construction of intelligent unmanned docks.

[0003] Currently, the unmanned surface vessel automatic charging equipment and system disclosed in CN114537177A includes a guide rail that is vertically positioned in the water and extends out of the water surface, a buoyancy device that is set on the water surface and provides buoyancy, and a dock hull set on the buoyancy device. The dock hull is a trough with an inlet. The dock hull is movably set on the guide rail. The inner wall of the dock hull is equipped with charging electrodes for docking with the unmanned surface vessel for charging. This allows the dock hull to change position with the rise and fall of the water level. At the same time, with the guide rail fixed, the dock hull will not be washed away by the water flow. The unmanned surface vessel can enter the interior of the dock hull at any time to dock with the charging electrodes for charging.

[0004] Regarding the aforementioned technologies, when a dock is deployed in waters with large waves, the waves will toss the dock from its deployment location and then crash it back onto the water. During this process, the dock is easily damaged, which greatly reduces its service life. Utility Model Content

[0005] To improve the service life of charging docks, this application provides an intelligent dock lifting device.

[0006] The intelligent dock lifting device provided in this application adopts the following technical solution:

[0007] A smart dock lifting device includes:

[0008] The mounting frame includes a support column, a connecting frame, and a guide rail. The support column is used to be fixedly connected to the foundation vertically. The connecting frame is fixedly connected to the support column, and the guide rail is fixedly connected to the support column along the length of the support column.

[0009] A charging dock includes a fixing component, a connecting component, and a charging dock. The fixing component is disposed on one side of the guide rail, the connecting component connects the fixing component to the guide rail, and the charging dock is fixedly connected to the fixing component.

[0010] The lifting component is fixedly connected at one end to the fixing component and at the other end to the connecting frame, so as to drive the fixing component to move along the guide rail.

[0011] By adopting the above technical solution, when the unmanned vessel is working in the water, the lifting component drives the fixing component to move upward. During the upward movement of the fixing component, the fixing component moves upward steadily and smoothly through the cooperation of the connecting component and the guide rail, thereby driving the charging dock to move upward smoothly. This allows the charging dock to leave the water surface, avoiding the impact of wind and waves on the dock, reducing the damage caused by wind and waves to the dock, and achieving the effect of improving the service life of the charging dock.

[0012] When the unmanned boat needs to be charged, the lifting component drives the fixing component to move downward. The fixing component, through the cooperation of the connecting component and the guide rail, stably drives the charging dock to move downward, so that the charging dock is on the water surface. Then, the unmanned boat is controlled to enter the charging dock for charging. After charging is completed, the charging dock is raised again and removed from the water surface.

[0013] By coordinating support columns, connecting frames, guide rails, lifting components, fixing components, connecting components, charging docks, and lifting components, the charging dock is only brought into contact with the water surface to charge the unmanned vessel when it needs to be charged. After the unmanned vessel is fully charged, the charging dock can be moved away from the water surface to avoid the impact of wind and waves on the dock, reduce the damage caused by wind and waves, and thus improve the service life of the charging dock.

[0014] Optionally, the guide rail includes a fixing plate, a connecting plate, and a contact plate. The fixing plate is fixedly connected to the support column. One end of the connecting plate is fixedly connected to the fixing plate, and the other end is fixedly connected to the contact plate. The connecting member includes a connecting seat, an abutment wheel, and a contact wheel. The connecting seat is fixedly connected to the fixing member. The abutment wheel and the contact wheel are both fixedly connected to the connecting seat. The abutment wheel and the contact wheel abut against both sides of the contact plate, respectively.

[0015] By adopting the above technical solution, the connecting plate and the contact plate are fixedly connected to the support column using a fixing plate, making the connection of the guide rail more stable. Then, the contact plate is clamped by the abutment wheel and the contact wheel, so that the connection between the connecting seat and the contact plate is a sliding connection. This greatly reduces the friction generated when the connecting parts and the guide rail move, making the charging dock move more smoothly up and down.

[0016] Optionally, the fixing component includes a horizontal bar, a vertical bar, an auxiliary bar, and a diagonal bar. The horizontal bar is horizontally arranged and there are multiple horizontal bars. There are multiple vertical bars and the vertical bars are fixedly connected to the horizontal bar. The lifting component is fixedly connected to the uppermost horizontal bar. The charging dock is fixedly connected to the lowermost horizontal bar. The auxiliary bar is fixedly connected to the charging dock, and one end of the auxiliary bar is fixedly connected to the horizontal bar. One end of the diagonal bar is fixedly connected to the uppermost horizontal bar, and the other end is fixedly connected to the end of the auxiliary bar away from the horizontal bar.

[0017] By adopting the above technical solution, the cooperation of the horizontal bar and the vertical bar makes the fixed part more stable when the lifting part lifts it. The auxiliary bar is used to increase the contact area between the fixed part and the charging dock and the range of fixed connection, making the overall movement of the charging dock more stable. At the same time, the two ends of the auxiliary bar are reinforced by the diagonal bar and the horizontal bar to form a triangular stable structure, making the overall movement of the charging dock more stable.

[0018] Optionally, a reinforcing rod may be provided between the auxiliary rod and the inclined rod.

[0019] By adopting the above technical solution, a reinforcing rod is added between the auxiliary rod and the diagonal rod, further improving the stability of the fixing component.

[0020] Optionally, the auxiliary rod is equipped with a collision protection device located below the charging dock.

[0021] By adopting the above technical solution, the anti-collision device prevents the unmanned boat from colliding with the bottom of the charging dock when it enters the dock.

[0022] Optionally, the anti-collision component includes an anti-collision frame and an anti-collision wheel. The anti-collision frame is fixedly connected to the auxiliary rod, and the anti-collision wheel is rotatably connected to the anti-collision frame, with the anti-collision wheel located below the charging dock.

[0023] By adopting the above technical solution, when the unmanned boat approaches the charging dock, the bottom of the unmanned boat is close to the anti-collision wheels, which stabilizes the bottom of the unmanned boat and prevents it from swaying, allowing the unmanned boat to dock and charge more stably with the charging dock.

[0024] Optionally, a level gauge is fixedly connected to the crossbar, and the level gauge is used to measure the distance from the water surface.

[0025] By adopting the above technical solution, the distance from the water surface is measured using a level gauge, which can stably dock the charging dock at a certain draft, thus facilitating stable charging of the unmanned vessel.

[0026] Optionally, a limit block is fixedly connected to the guide rail, a limit switch is fixedly connected to the limit block, and a trigger is installed on the crossbar, the movement path of the trigger being located on the trigger of the limit switch.

[0027] By adopting the above technical solution, and utilizing the cooperation of limit blocks, limit switches and triggers, the lifting components automatically stop working when the charging dock reaches its maximum height, preventing the charging dock from exceeding its lifting range and improving the automation of the charging dock lifting process.

[0028] Optionally, the lifting component includes an electric hoist and a traction rope. The electric hoist is fixedly connected to the connecting frame, and one end of the traction rope is connected to the electric hoist, while the other end is fixedly connected to the crossbar.

[0029] By adopting the above technical solution, the electric hoist is used to rewind the traction rope to control the horizontal bar to move upward, thereby driving the charging dock to move upward. Meanwhile, the electric hoist unwinds the traction rope, and the charging dock moves downward under its own weight.

[0030] Optionally, a lifting block is installed on the crossbar, and a number of lifting ears are fixedly connected to the lifting block, with the traction rope threaded through each of the lifting ears.

[0031] By adopting the above technical solution, the lifting block and lifting ear work together to achieve multi-node distributed force, avoid the risk of single-point breakage, and limit the swing amplitude of the crossbar, thus extending its service life.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] Through the cooperation of support columns, connecting frames, guide rails, lifting parts, fixing parts, connecting parts, charging docks and lifting parts, the charging dock is only brought into contact with the water surface to charge the unmanned boat when it needs to be charged. After the unmanned boat is charged, the charging dock can be moved away from the water surface to avoid the impact of wind and waves on the dock, reduce the damage of wind and waves to the dock, and achieve the effect of improving the service life of the charging dock.

[0034] The cooperation of the fixed plate, connecting plate, contact plate, connecting seat, abutment wheel and contact wheel makes the connection of the guide rail more stable. The abutment wheel and contact wheel are used to clamp the contact plate, so that the connection between the connecting seat and the contact plate is a sliding connection. This greatly reduces the friction generated when the connecting parts and the guide rail move, making the charging dock move more smoothly up and down.

[0035] By coordinating the horizontal bars, vertical bars, auxiliary bars, and diagonal bars, the lifting components can lift the fixed components, making the fixed components more stable under force. The auxiliary bars further increase the contact area between the fixed components and the charging dock and the range of fixed connection, making the overall movement of the charging dock more stable. At the same time, the diagonal bars and horizontal bars reinforce the two ends of the auxiliary bars, forming a triangular stable structure, which makes the overall movement of the charging dock more stable.

[0043] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0044] This application discloses an intelligent dock lifting device.

[0045] Reference Figure 1-3The intelligent dock lifting device includes a mounting frame 1, a charging dock 2, and a lifting component 3. The mounting frame 1 includes a support column 11, a connecting frame 12, and a guide rail 13. The support column 11 is vertically fixed to the foundation, the connecting frame 12 is fixedly connected to the support column 11, and the guide rail 13 is fixedly connected to the support column 11 along its length. The charging dock 2 includes a fixing component 21, a connecting component 22, and a charging dock 23. The fixing component 21 is located on one side of the guide rail 13, the connecting component 22 connects the fixing component 21 to the guide rail 13, and the charging dock 23 is fixedly connected to the fixing component 21. The lifting component 3 is fixedly connected at one end to the fixing component 21 and at the other end to the connecting frame 12, driving the fixing component to move along the guide rail 13. This design ensures that the charging dock 23 is only brought into contact with the water surface to charge the unmanned vessel when it needs to be charged. Once the unmanned vessel is fully charged, the charging dock 23 can be removed from the water surface, preventing waves from impacting the dock and reducing damage from waves, thereby extending the service life of the charging dock 23.

[0046] In this embodiment, the support column 11 is cast in a 'door' shape, and the connecting frame 12 is fixedly connected to the top of the support column 11. The connecting frame 12 facilitates the installation of the lifting component 3. The guide rail 13 is made of 'I' shaped steel, and therefore includes a fixing plate 131, a connecting plate 132, and a contact plate 133. The fixing plate 131 is fixedly connected to the support column 11, and one end of the connecting plate 132 is fixedly connected to the fixing plate 131, while the other end is fixedly connected to the contact plate 133. By using the fixing plate 131 to fix the connecting plate 132 and the contact plate 133 to the support column 11, the connection of the guide rail 13 becomes more stable.

[0047] Reference Figure 3 and Figure 4 The connector 22 includes a connecting seat 221, an abutment wheel 222, and a contact wheel 223. The connecting seat 221 is fixedly connected to the fixing member 21. The abutment wheel 222 and the contact wheel 223 are both fixedly connected to the connecting seat 221. In this embodiment, the abutment wheel 222 is larger, while the contact wheel 223 is smaller. There are four contact wheels 223, which are distributed in pairs on both sides of the connecting plate 132. The abutment wheel 222 and the contact wheel 223 abut against both sides of the contact plate 133. The contact plate 133 is clamped by the abutment wheel 222 and the contact wheel 223, so that the connection between the connecting seat 221 and the contact plate 133 is a sliding connection. This greatly reduces the friction generated when the connector 22 moves with the guide rail 13, making the charging dock 23 move more smoothly up and down.

[0048] Reference Figure 2The fixing component 21 includes a horizontal bar 211, a vertical bar 212, an auxiliary bar 213, and a diagonal bar 214. The horizontal bar 211 is set horizontally and there are multiple horizontal bars. In this embodiment, there are 2 horizontal bars 211, but in other embodiments, there may be 3 or 4.

[0049] Multiple uprights 212 are arranged vertically. In this embodiment, two uprights 212 are provided, and the two uprights 212 correspond one-to-one with the two guide rails 13. In other embodiments, three or four uprights may also be provided. The uprights 212 are fixedly connected to the crossbars 211, and the connecting seats 221 are fixedly connected to the uprights 212. Two connecting seats 221 are fixedly connected to the same upright 212, making the connection between the uprights 212 and the guide rails 13 more stable.

[0050] By utilizing the cooperation of the horizontal bar 211 and the vertical bar 212, the fixed part 21 is more stable under force when the lifting part 3 lifts the fixed part 21.

[0051] The lifting component 3 is fixedly connected to the uppermost horizontal bar 211, and the charging dock 23 is fixedly connected to the lowermost horizontal bar 211. The auxiliary rod 213 is fixedly connected to the charging dock 23, with one end of the auxiliary rod 213 fixedly connected to the horizontal bar 211, and one end of the diagonal rod 214 fixedly connected to the uppermost horizontal bar 211, and the other end fixedly connected to the end of the auxiliary rod 213 furthest from the horizontal bar 211. The auxiliary rod 213 increases the contact area and fixed connection range between the fixing component 21 and the charging dock 23, making the overall movement of the charging dock 23 more stable. Simultaneously, the diagonal rod 214 and the horizontal bar 211 reinforce both ends of the auxiliary rod 213, forming a triangular stable structure, further enhancing the stability of the charging dock 23 during its overall movement.

[0052] In an optional embodiment, a reinforcing rod 215 is further provided between the auxiliary rod 213 and the diagonal rod 214. By adding the reinforcing rod 215 between the auxiliary rod 213 and the diagonal rod 214, the stability of the fixing member 21 is further improved.

[0053] The auxiliary pole 213 is equipped with a collision avoidance component 4, which includes a collision avoidance frame 41 and a collision avoidance wheel 42. The collision avoidance frame 41 is fixedly connected to the auxiliary pole 213, and the collision avoidance wheel 42 is rotatably connected to the collision avoidance frame 41, with the collision avoidance wheel 42 located below the charging dock 23. The collision avoidance component 4 is designed to prevent the unmanned vessel from colliding with the bottom of the charging dock 23 when it enters the charging dock 23.

[0054] When the unmanned boat approaches the charging dock 23, its bottom approaches the anti-collision wheel 42, which stabilizes the bottom of the unmanned boat, preventing it from colliding with the bottom of the charging dock 23 and also preventing the unmanned boat from swaying. This allows the unmanned boat to dock and charge more stably with the charging dock 23.

[0055] The lifting assembly includes an electric hoist 31 and a traction rope 32. The electric hoist 31 is fixedly connected to the connecting frame 12. One end of the traction rope 32 is connected to the electric hoist 31, and the other end is fixedly connected to the crossbar 211. The electric hoist 31 rewinds the traction rope 32 to control the crossbar 211 to move upward, thereby driving the charging dock 23 to move upward. Conversely, the electric hoist 31 unwinds the traction rope 32, causing the charging dock 23 to move downward under its own weight.

[0056] Reference Figure 5 In one optional embodiment, a lifting block 5 is installed on the crossbar 211, and several lifting ears 51 are fixedly connected to the lifting block 5. The traction rope 32 is threaded through the lifting ears 51. By utilizing the cooperation of the lifting block 5 and the lifting ears 51, the force is distributed across multiple nodes, avoiding the risk of single-point breakage. At the same time, it also limits the swing amplitude of the crossbar 211 and extends its service life.

[0057] Reference Figure 3 A level gauge 6 is fixedly connected to the crossbar 211. In this embodiment, an ultrasonic level gauge 6 is used to measure the distance from the water surface, thereby stabilizing the charging dock 23 at a certain draft, which facilitates stable charging of the unmanned vessel.

[0058] A limit block 7 is fixedly connected to the guide rail 13, and a limit switch 71 is fixedly connected to the limit block 7. A trigger 72 is installed on the crossbar 211, and the movement path of the trigger 72 is located at the triggering point of the limit switch 71. In this embodiment, the limit switch 71 is a magnetic limit switch 71, and the trigger 72 is a magnet. When the trigger 72 moves to the triggering position of the limit switch 71, that is, when the charging dock 23 reaches its maximum height, the limit switch 71 is triggered, causing the electric hoist 31 to automatically stop working, preventing the charging dock 23 from exceeding its lifting range, and improving the automation of the charging dock 23 lifting process.

[0059] In this embodiment, an ultrasonic rangefinder 8 is also installed on the crossbar 211, and the ultrasonic rangefinder 8 faces the top of the mounting frame 1. The ultrasonic rangefinder 8 measures the distance to the top of the mounting frame 1, so that the position information of the charging dock 23 can be directly obtained. It can be set to control the electric hoist 31 to stop working when the ultrasonic detector detects that it is in a certain position.

[0060] The implementation principle of the intelligent dock lifting device in this application embodiment is as follows: When the unmanned vessel is working in the water, the electric hoist 31 winds up the traction rope 32 to drive the fixing member 21 to move upward. During the upward movement of the fixing member 21, the fixing member 21 contacts the guide rail 13 through the abutment wheel 222 and the contact wheel 223, so that the fixing member 21 can move upward steadily and smoothly, thereby driving the charging dock 23 to move upward smoothly. When the trigger 72 moves to the trigger position of the limit switch 71, that is, the charging dock 23 reaches the maximum height, the limit switch 71 is triggered, so that the electric hoist 31 automatically stops working. At this time, the charging dock 23 can be completely lifted off the water surface, avoiding the impact of wind and waves on the dock, reducing the damage of wind and waves to the dock, and achieving the effect of improving the service life of the charging dock 23. At the same time, it can intelligently stop at a suitable height.

[0061] When the unmanned vessel needs to be charged, the electric hoist 31 unwinds the towing rope 32, and the fixing part 21 and the charging dock 23 move slowly downward under the action of gravity. After the level gauge 6 measures the distance from the water surface, and the measurement reaches a suitable distance, the electric hoist 31 automatically stops working, and the charging dock 23 automatically stops at a suitable draft. Then, the unmanned vessel is controlled to enter the charging dock 23 for charging. After charging is completed, the charging dock 23 is raised again and removed from the water surface.

[0062] This design ensures that the charging dock 23 is only brought into contact with the water surface to charge the unmanned vessel when it needs to be charged. Once the unmanned vessel is fully charged, the charging dock 23 can be removed from the water surface, preventing waves from impacting the dock and reducing damage from waves, thereby extending the service life of the charging dock 23.

[0063] Meanwhile, the combination of limit switch 71 and level gauge 6 enables the charging dock 23 to automatically stop after rising or falling to a suitable height, allowing the charging dock 23 to intelligently identify the preset suitable height during the lifting and lowering process, and thus intelligently charge the unmanned boat.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
