Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV take-off and landing platform. Background Technology

[0002] With the rapid development of drone technology, its application scenarios have gradually expanded from land to aquatic environments such as oceans, rivers, and lakes. The demand for applications in areas such as navigational aid inspection, resupply to isolated islands, maritime search and rescue, and marine environmental monitoring is becoming increasingly urgent. During drone operations on water, docking and takeoff / landing are crucial for ensuring mission completion. However, the disturbances caused by natural factors such as wind, waves, and currents on the water's surface present numerous technical challenges to stable drone docking. Existing drone water landing platforms still have significant shortcomings in design and application, making it difficult to meet the safe and efficient docking requirements of drones in complex aquatic environments.

[0003] Traditional drone water landing platforms generally suffer from poor wave resistance. In turbulent waters with wind, waves, and currents, the platform is prone to tilting and swaying with the water's movement, making it impossible to maintain a stable horizontal position. This results in a significant decrease in positioning accuracy when the drone docks, and may even lead to accidents such as the drone overturning or falling into the water, seriously affecting the operational safety and equipment integrity of the drone.

[0004] Therefore, to solve the above problems, a highly adaptable take-off and landing platform is needed to facilitate the recovery and docking of drones. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a drone take-off and landing platform to solve the technical problem of difficulty in docking drones on turbulent water surfaces.

[0006] To achieve the above and other related objectives, the present invention provides an unmanned aerial vehicle (UAV) take-off and landing platform, which is installed on a shipborne platform and includes: a take-off and landing platform body, the take-off and landing platform body having a receiving cavity, a horizontal stabilization component, a lifting component and a charging component being disposed in the receiving cavity, the horizontal stabilization component being rotatably disposed on the upper side of the lifting component, and the charging component being located on one side of the horizontal stabilization component and the lifting component;

[0007] The horizontal stabilization assembly includes a stabilization mechanism and a limiting mechanism. The stabilization mechanism includes a lifting platform, a rotating plate, a first motor, a first adjusting block, a second motor, a second adjusting block, and a rotating part. The rotating plate is positioned above the lifting assembly via the rotating part. The first motor and the second motor are fixedly mounted on the rotating plate. The output shaft axes of the first motor and the second motor are perpendicular to each other and are positioned on the same horizontal plane towards the center. The first adjusting block and the second adjusting block are both arc-shaped. The outer center of the first adjusting block is fixedly connected to the output end of the first motor. A connecting column is located at the center of the lower side of the lifting platform. A first rotating shaft and a second rotating shaft are mounted on the connecting column. The axes of the first rotating shaft and the second rotating shaft are perpendicular to each other. The first adjusting block is located outside the connecting column, and the inner sides of both ends of the first adjusting column are rotatably connected to the first rotating shaft. One end of the outer side of the second adjusting block is fixedly connected to the output end of the second motor, and the other end is rotatably connected to the second rotating shaft.

[0008] In this way, when the ship is rocking, the dual motors work together to drive the dual adjustment blocks to counteract the longitudinal and lateral wave disturbances in real time, so that the landing platform always maintains a horizontal attitude. The rotating part and the dual rotating shafts form a universal leveling mechanism, which works with the lifting components to dynamically compensate for the water surface fluctuations. This ensures that the landing platform is linked with the ship's motion attitude under complex water conditions, making the attitude of the landing platform easy for the UAV to land and allowing the UAV to dock stably on the landing platform.

[0009] Optionally, the landing platform includes a buffer platform and a stabilizing platform. The buffer platform is mounted on the stabilizing platform via a buffer mechanism. The connecting column is fixedly installed in the middle of the lower part of the stabilizing platform. The buffer mechanism includes a first elastic buffer rod, a connecting plate, and a second elastic buffer rod. Both the first and second elastic buffer rods are vertically arranged. The upper end of the first elastic buffer rod is fixedly installed below the buffer platform and located at the center of gravity of the buffer platform. The lower end of the first elastic buffer rod is connected to the center of the upper part of the stabilizing platform via a universal ball joint connection structure. The second elastic buffer rods are evenly distributed around the outer periphery of the first elastic buffer rod. The lower end of the second elastic buffer rod is fixedly installed on the stabilizing platform, and the upper end is hinged to the lower end of the connecting plate. The upper end of the connecting plate is hinged to the lower side of the buffer platform. By using the first elastic buffer rod and the universal ball joint connection mechanism, the impact with the buffer platform during drone landing is reduced, thus reducing the risk of drone collisions. The evenly distributed second elastic buffer rods ensure that the buffer platform and the stabilizing platform remain horizontal.

[0010] Optionally, the lifting assembly includes a lifting section and a driving section. The lifting section includes a lifting plate, linear slide rail modules, an upper fixed plate, a lower fixed plate, and a movable plate. The upper fixed plate is vertically mounted downwards on the underside of the lifting plate. Linear slide rail modules are provided on both sides of the movable plate. The lower fixed plate is vertically mounted and its lower end is fixedly installed at the bottom of the receiving cavity. The linear slide rail modules on both sides of the movable plate are respectively connected to the upper fixed plate and the lower fixed plate. The driving section is connected to the upper fixed plate and is used to drive the upper fixed plate to move vertically. By providing linear slide rail modules on both sides of the movable plate, both the movable plate and the upper fixed plate can move vertically, achieving two-stage lifting. This facilitates the vertical movement of the lifting plate, enabling dynamic compensation of water surface undulations and facilitating the recovery of the UAV into the charging chamber.

[0011] Optionally, the drive unit includes a drive motor, a first threaded rod, a second threaded rod, a splined shaft, a fixed frame, and a movable frame. The fixed frame is fixedly installed at the bottom of the receiving cavity, and the drive motor is fixedly installed on the fixed frame. The splined shaft, the first threaded rod, and the second threaded rod are all vertically installed. The first threaded rod is threadedly connected to the upper fixed plate. The first threaded rod is hollow and has a hole that matches the splined shaft. The first threaded rod and the splined shaft are coaxial and splined. The lower end of the splined shaft is rotatably mounted on the fixed frame via a rolling bearing. The second threaded rod... The threaded rod is rotatably mounted in the fixed frame, located on one side of the splined shaft. The movable frame is horizontally arranged. The lower end of the first threaded rod is rotatably connected to the movable frame via a rolling bearing. The second threaded rod and the movable frame are threadedly engaged. The second threaded rod and the output end of the drive motor have meshing gears. The lower end of the splined shaft and the lower end of the second threaded rod are connected via a synchronous belt pulley mechanism. The drive motor drives the second threaded rod to rotate. The synchronous belt pulley mechanism drives the splined shaft to rotate when the second threaded rod rotates, thereby causing the first threaded rod above the splined shaft to rotate. The drive motor can simultaneously drive the rotation of the first threaded rod and the splined shaft. Due to the sliding fit between the splined shaft and the first threaded rod, the rotation of the splined shaft can simultaneously drive the rotation of the first threaded rod. The first threaded rod is threadedly connected to the upper fixed plate, and the rotation of the first threaded rod can cause the upper fixed plate to move in the vertical direction. The second threaded rod is threadedly connected to the moving frame, and the rotation of the second threaded rod can cause the moving frame to move in the vertical direction. The lower end of the first threaded rod is rotatably mounted on the moving frame. When the moving frame moves in the vertical direction, it can simultaneously cause the first threaded rod and its upper fixed plate to move in the vertical direction. The spline fit between the splined shaft and the first threaded rod can keep the first threaded rod rotating during the vertical movement, so that the upper fixed plate moves synchronously in the vertical direction.

[0012] Optionally, the rotating part includes a third rotating shaft, a gear and rack module, and an electric push rod. The third rotating shaft is rotatably mounted in the middle of the lifting plate via rolling bearings. The upper end of the third rotating shaft passes through the lifting plate and is fixedly connected to the lower side of the rotating plate. The electric push rod is fixedly mounted on the lower side of the lifting plate. The actuating end of the electric push rod and the lower end of the third rotating shaft are connected via the gear and rack module. The rack of the gear and rack module is mounted on the lower side of the lifting plate via a linear bearing and is fixedly connected to the actuating end of the electric push rod. The gear of the gear and rack is fixedly mounted on the third rotating shaft. The electric push rod and gear and rack module facilitate the rotation of the third rotating shaft, making it easy to adjust the lifting platform to maintain its horizontal position.

[0013] Optionally, the limiting mechanism is disposed on the stabilizing platform. The limiting mechanism includes a frame, limiting rods, and a second drive unit. The frame is fixedly installed on the stabilizing platform. The limiting rods are four in number, arranged in a grid pattern in pairs, and mounted on the upper side of the buffer platform. The second drive unit drives the limiting rods to move closer or further apart from each other simultaneously, centering the drone in the middle of the buffer platform. By using the second drive unit to move the limiting rods, the drone is pushed to the center position after landing, facilitating the drone recovery mechanism to recover the drone.

[0014] Optionally, the second drive unit includes a limit motor, several bidirectional ball screws, and several limit blocks. The bidirectional ball screws are symmetrically arranged in pairs and rotatably mounted on the frame. The ends of adjacent bidirectional ball screws have meshing bevel gears. The limit motor is fixedly mounted on the frame, and its output end is connected to the bidirectional ball screws via a synchronous belt pulley mechanism. The limit blocks are respectively fixedly mounted on two nuts of the bidirectional ball screws. The limit rods are fixedly mounted between the limit blocks on the symmetrically arranged bidirectional ball screws. When the limit motor is started, it can drive one bidirectional ball screw to rotate, and then use the meshing bevel gears to rotate all the bidirectional ball screws, thereby causing the limit rods to move closer or further apart. By utilizing the different directions of the threads at both ends of the bidirectional ball screws, the limit blocks can move closer or further apart when the bidirectional ball screws rotate, thereby causing the limit rods to move closer or further apart, thus limiting and clamping the UAV.

[0015] Optionally, the charging assembly includes a charging rack, a drone recovery mechanism, and a charging mechanism. The charging rack is fixedly installed inside the receiving cavity and located on one side of the horizontal stabilizing component. The upper side of the charging rack has several layers of charging chambers. The drone recovery mechanism is located within the charging chambers. The charging mechanism includes an energy storage control box and a flexible charging rack. The energy storage control box is fixedly installed at the bottom of the receiving cavity and located below the charging rack. The flexible charging rack is installed within the charging chambers. The charging assembly can charge drones, and the multi-layered charging chambers can store multiple drones, enabling drones to work alternately or simultaneously, improving work efficiency.

[0016] Optionally, the flexible charging rack includes a mounting plate, a fixed tube, a movable tube, a spring, and a magnetic charging module. The mounting plate is fixedly installed on the side of the charging chamber away from the horizontal stabilizing component. The fixed tube is horizontal on the mounting plate and faces the side of the horizontal stabilizing component. The movable tube is inserted into the fixed tube. The fixed tube has a through-hole limiting groove. One end of the movable tube inside the fixed tube has a limiting protrusion that mates with the limiting groove. The spring is sleeved on the outside of the fixed tube, and both ends of the spring are fixedly connected to the mounting plate and the limiting protrusion, respectively. The magnetic charging module is fixedly installed on the end of the movable tube away from the mounting plate. The flexible charging rack allows for soft docking during drone charging, reducing collisions between the drone and the magnetic charging module and preventing damage from collisions. The limiting groove and limiting block facilitate the separation of the drone from the magnetic charging module.

[0017] Optionally, the drone recovery mechanism includes an electromagnet module, a first electric guide rail module, and a second electric guide rail module. The first electric guide rail module is fixedly installed in the charging chamber, and the lower end of the second electric guide rail module is fixedly installed on the slider of the first electric guide rail module. The driving directions of both the first and second electric guide rail modules are oriented towards the side of the horizontal stabilizing component. The electromagnet module is fixedly installed on the slider of the second electric guide rail module. The first and second electric guide rail modules facilitate the transport of the drone from the buffer platform back to the charging chamber for charging or from the charging chamber to the buffer platform to await takeoff commands after the electromagnet module is magnetically attached to the drone.

[0018] The beneficial effects of this invention are as follows:

[0019] When using this invention, on the one hand, by utilizing the synergistic effect of the rotating part, the first motor, the second motor, and the lifting assembly, the landing platform can be kept horizontally stable in real time according to the water environment, which facilitates the landing of the drone, reduces the occurrence of accidents such as drone rollover and falling into the water, and improves the safety of drone operations; on the other hand, by using the charging assembly to charge the drone, the drone's battery life and working efficiency can be improved.

[0029] like Figure 1 As shown, a drone take-off and landing platform includes: a main body 1, which is mounted on a shipboard platform to enable drone take-off and landing with minimal space requirements; the main body 1 has an openable and closable door 11 and an internal cavity 12, within which are housed a horizontal stabilization component 2, a lifting component 3, and a charging component 4; the door 11 is sealed closed in standby mode and opened during operation. The horizontal stabilization component 2 is positioned above the lifting component 3 and can move up and down via the lifting component 3; the charging component 4 is located on one side of the horizontal stabilization component 2 and the lifting component 3; and several sensors are installed within the cavity 12 to monitor the status of the drone, its various mechanisms, and the ship, enabling linkage between the invention and the ship's motion attitude, facilitating drone take-off, landing, recovery, and charging.

[0030] like Figures 2-3 As shown, in this embodiment, the charging component 4 includes a charging rack 41, a drone recovery mechanism 42, and a charging mechanism 43. The charging rack 41 is fixedly installed in the receiving cavity 12 and located on one side of the horizontal stabilizing component 2. The charging rack 41 has three layers of charging chambers 411 in the vertical direction, which can charge three drones.

[0031] Specifically, the charging mechanism 43 includes an energy storage control box 431 and a flexible charging rack 432. The energy storage control box 431 has a battery and an electronic control system, and is installed below the charging rack 41 to automate the landing, recovery, charging, or takeoff of the drone. The flexible charging rack 432 is installed in each charging chamber 411 and includes a mounting plate 4321, a fixed tube 4322, a moving tube 4323, a spring 4324, and a magnetic charging module 4325. The mounting plate 4321 is fixedly installed on the side of the charging chamber 411 away from the horizontal stabilizing component 2. The fixed tube 4322 is horizontally fixed on the mounting plate 4321 along its axis. The moving tube 4323 is inserted into and slidably fitted at the end of the fixed tube 4322 away from the mounting plate 4321. The fixed tube 4322 has a limiting groove 4326, and the moving tube 4323 has an outwardly protruding limiting protrusion 4327 corresponding to the limiting groove 4326 to prevent the moving tube 4323 from moving. The spring 4324 is sleeved on the outside of the fixed tube 4322 and its two ends are fixedly connected to the mounting plate 4321 and the limiting protrusion 4327, respectively. The fixed tube 4322 and the moving tube 4323 are hollow to facilitate wiring. The magnetic charging module 4325 is fixedly installed at the end of the moving tube 4323 away from the mounting plate 4321. After the drone is retrieved by the drone retrieval mechanism 42, it can come into contact with the magnetic charging module 4325 and then charge. The spring 4324 reduces the impact force when the drone comes into contact with the magnetic charging module 4325, effectively avoiding damage to the drone and the magnetic charging module 4325.

[0032] Specifically, the drone recovery mechanism 42 includes a first electric guide rail module 421, a second electric guide rail module 422, and an electromagnet module 423. The first electric guide rail module 421 is fixedly installed inside the charging chamber 411, and the lower side of the second electric guide rail module 422 is fixedly installed on the slider of the first electric guide rail module 421. The driving directions of both the first and second electric guide rail modules 421 and 422 are set towards the side of the horizontal stabilizing component 2. The electromagnet module 423 is fixedly installed on the slider of the second electric guide rail module 422. The drone is magnetically attracted and fixed by the electromagnet module 423 to prevent the drone from moving. The two-stage telescopic mechanism formed by the two electric guide rail modules can quickly extend or shorten, facilitating the recovery or release of the drone. The combination of electric guide rail modules reduces the overall length of the charging chamber 411, making the invention occupy less space and easier to place and install.

[0033] like Figure 2 and Figure 4 As shown, in this embodiment, the horizontal stabilization component 2 includes a stabilization mechanism 21 and a limiting mechanism 22. The stabilization mechanism 21 is used to ensure that the UAV maintains a horizontal landing when landing, and the limiting mechanism 22 is used to limit the UAV to facilitate the recovery of the UAV. The limiting mechanism 22 is located on the stabilization mechanism 21.

[0034] Specifically, the stabilizing mechanism 21 includes a lifting platform 211, a rotating plate 212, a first motor 213, a first adjusting block 214, a second motor 215, a second adjusting block 216, and a rotating part 217. The rotating plate 212 is horizontally rotatable above the lifting assembly 3 via the rotating part 217. The first motor 213 and the second motor 215 are fixedly mounted above the rotating plate 212. The output shaft axes of the first motor 213 and the second motor 215 are horizontally arranged and perpendicular to each other, both facing the central axis of the rotating plate 212. The first adjusting block 214 is arranged in a semi-circular arc, and the second adjusting block 216 is arranged in a quarter-circular arc. The outer middle part of the first adjusting block 214 is fixedly connected to the output shaft of the first motor 213 via a coupling, and the outer side of one end of the second adjusting block 216 is connected via a coupling. Connected to the output shaft of the second motor 215, the lower side of the lifting platform 211 has a connecting column 2111 in the middle. The connecting column 2111 is provided with a first rotating shaft 2112 and a second rotating shaft 2113. The top end of the first rotating shaft 2112 is rotatably connected to both ends of the first adjusting block 214 through rolling bearings. The second rotating shaft 2113 is rotatably connected to the end of the second adjusting block 216 away from the second motor 215 through rolling bearings. When the first motor 213 is started, it can make the connecting column 2111 and the lifting platform 211 rotate around the second rotating shaft 2113. When the second motor 215 is started, it can make the connecting column 2111 and the lifting platform 211 rotate around the first rotating shaft 2112. In conjunction with the rotating part 217, the state of the lifting platform 211 is adjusted in real time to ensure that the lifting platform 211 always remains in a horizontal state.

[0035] like Figures 4-5As shown, in this embodiment, the landing platform 211 includes a buffer platform 2114 and a stabilizing platform 2115 arranged in parallel. The buffer platform 2114 is mounted on the upper side of the stabilizing platform 2115 via a first elastic buffer rod 2116. The upper end of the first elastic buffer rod 2116 is fixedly connected to the lower end of the buffer platform 2114, and the lower end is connected to the stabilizing platform 2115 via a universal ball joint connection mechanism 2117. The axis of the first elastic buffer rod 2116 is collinear with the central axis of the buffer platform 2114 and the stabilizing platform 2115. Three second elastic buffer rods 2118 are also provided between the buffer platform 2114 and the stabilizing platform 2115, and the three second elastic buffer rods 2118 are evenly distributed circumferentially around the outer periphery of the first elastic buffer rod 2116. The lower end of the second elastic buffer rods 2118 is connected to the lower end of the first elastic buffer rod 2115. The stabilizing platform 2115 is fixedly connected, and a connecting plate 2119 is hinged between the upper end of the second elastic buffer rod 2118 and the buffer platform 2114. The first elastic buffer rod 2116 can buffer the drone when it lands, reducing the impact force and preventing damage to the drone. The universal ball joint connecting mechanism 2117 and the second elastic buffer rod 2118 can change the angle of the buffer platform 2114 when the drone lands in a non-centered position, further buffering the drone. The second elastic buffer rod 2118 can pull each other to quickly keep the buffer platform 2114 level with the stabilizing platform 2115 after the angle changes, facilitating the recovery of the drone.

[0036] Specifically, the connecting column 2111 is fixedly installed on the lower side of the stabilizing platform 2115. The axis of the connecting column 2111 is collinear with the central axis of the stabilizing platform 2115. The connecting column 2111 is also provided with a mounting groove 21111. A horizontal sensor 21112 for detecting the status of the stabilizing platform 2115 is installed in the mounting groove 21111. The horizontal sensor 21112 ensures that the stabilizing platform remains stable when the ship sways due to wind and waves.

[0037] The limiting mechanism 22 includes a frame 221, a limiting rod 222, a limiting motor 223, a bidirectional ball screw module 224, and limiting blocks 225. The frame 221 is fixedly mounted on a stabilizing platform 2115. Four bidirectional ball screw modules 224 are arranged in a U-shape on the frame 221 and evenly distributed around the outer periphery of the buffer platform 2114. The limiting blocks 225 are mounted on nuts with different directions of rotation at both ends of the bidirectional ball screw module 224. When the screw of the bidirectional ball screw module 224 rotates, the limiting blocks 225 move closer or further apart under the influence of the nuts. The limiting rod... The two ends of 222 are respectively fixedly installed on the limit blocks 225 on the same side of two parallel bidirectional ball screw modules 224. The limit rods 222 are arranged in a grid shape with four rods. When the bidirectional ball screw module 224 rotates, the four limit rods 222 can move closer or further away from each other at the same time, thereby limiting the drone after landing and pushing the drone to a position that is easy to recover. The limit motor 223 is fixedly installed on the frame 221 and connected to the bidirectional ball screw module 224 through the synchronous belt pulley mechanism 226, thereby driving the bidirectional ball screw in the bidirectional ball screw module 224 to rotate.

[0038] In this embodiment, the ends of the bidirectional ball screw modules 224 are meshed with gears, and the bidirectional screws of all the bidirectional ball screw modules 224 are driven to rotate by a set of limit motors 223 and synchronous belt pulley mechanisms 226.

[0039] Specifically, in order to facilitate the electromagnet module 423 in grasping the drone, a clearance groove 2211 is provided on the frame 221 on the side near the charging chamber 411. On both sides of the clearance groove 2211, limit blocks 225 are installed using ball screw modules 227, so that the second electric guide rail module 422 can be more easily extended into the buffer platform 2114 to grasp the drone and avoid mutual interference between mechanisms.

[0040] like Figures 6-7As shown, in this embodiment, the lifting assembly 3 includes a lifting part 31 and a driving part 32. The lifting part 31 includes a lifting plate 311, a linear slide rail module 312, an upper fixed plate 313, a lower fixed plate 314, and a moving plate 315. The upper end of the upper fixed plate 313 is fixedly installed on the lower side of the lifting plate 311, and the upper fixed plate 313 is installed vertically downwards. The lower end of the lower fixed plate 314 is fixedly installed on the bottom of the receiving cavity 12, and the lower fixed plate 314 is installed vertically upwards. The moving plate 315 is vertically arranged between the upper fixed plate 313 and the lower fixed plate 315. Linear slide rail modules 312 are provided between the upper fixed plate 313 and the lower fixed plate 314, and are located on both sides near the upper fixed plate 313 and the lower fixed plate 314. The upper fixed plate 313 and the lower fixed plate 314 are respectively engaged with the two linear slide rails. The drive unit 32 is located between the upper fixed plate 313 and the bottom of the receiving cavity 12. By using the drive unit 32 and through the two linear slide rail modules 312, the upper fixed plate 313 can drive the lifting plate 311 to move in the vertical direction and achieve a folding effect, so that the lifting plate 311 can descend more and reduce the overall volume of the device.

[0041] Specifically, in order to make the movement of the lifting plate 311 more stable, two sets of upper fixed plate 313, lower fixed plate 314 and moving plate 315 are symmetrically arranged.

[0042] Specifically, the drive unit 32 includes a drive motor 321, a first threaded rod 322, a second threaded rod 323, a splined shaft 324, a fixed frame 325, and a movable frame 326. The fixed frame 325 is fixedly installed at the bottom of the receiving cavity 12. The drive motor 321 is fixedly installed on the fixed frame 325. The second threaded rod 323 and the splined shaft 324 are vertically rotatably installed in the fixed frame 325 via rolling bearings. The lower ends of the second threaded rod 323 and the splined shaft 324 are connected by a synchronous pulley 327. The output shaft of the drive motor 321 and the second threaded rod 323 are connected by a meshing gear 328. When the drive motor 321 starts, it can simultaneously drive the second threaded rod 323 and the splined shaft 324 to rotate. The movable plate 315 is horizontally arranged in the fixed frame 325 and threadedly connected to the second threaded rod 323. When the drive motor 321 starts, the movable plate 315 moves axially on the second threaded rod 323 through the threaded engagement. The rod 322 is vertically arranged, and its lower end is rotatably mounted on the movable plate 315 via a rolling bearing. The upper end of the first threaded rod 322 is threadedly connected to the upper fixed plate 313. The first threaded rod 322 is axial and has a hole that matches the spline shaft 324. The lower end of the first threaded rod 322 is splinedly engaged with the upper end of the spline shaft 324. When the spline shaft 324 rotates, it drives the first threaded rod 322 to rotate, causing the upper fixed plate 313 to move axially on the first threaded rod 322. This allows the lifting part 31 to move in the vertical direction. By utilizing the cooperation between the spline shaft 324 and the first threaded rod 322, when the movable plate 315 moves upward, the first threaded rod 322 can move upward and rotate synchronously, further causing the upper fixed plate 313 to move axially on the first threaded rod 322. By using a single drive part 32, the lifting plate 311 can be displaced more in the vertical direction, reducing the overall height and volume of the invention, and facilitating the transportation and installation of the device.

[0043] Specifically, the rotating part 217 includes a third rotating shaft 2171, a gear and rack module 2172, and an electric push rod 2173. The third rotating shaft 2171 is vertically rotatably mounted on the lifting plate 311 via rolling bearings.
