They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0035] This embodiment provides a marine electric launch and recovery device. The device has a compact overall design, makes full use of the cabin and reduces the space occupied by the cabin. It also has good resistance to wind and waves, a high degree of automation, and uses all-electric drive as a clean energy source. Electricity is directly driven, avoiding power conversion, resulting in high drive efficiency and reduced energy consumption.
[0036] Combination Figures 1 to 4 As shown, the marine electric launch and retraction device of this embodiment includes a bracket 10, a drive unit 20, and a maintenance compartment 30. The bracket 10 serves as a support structure for mounting the drive unit 20 and the maintenance compartment 30. The drive unit 20 enables the launch and retraction of the measuring device 24, while the maintenance compartment 30 facilitates routine inspection and maintenance of the measuring device 24 within the ship's cabin.
[0037] In this embodiment, the marine electric launching and retracting device also includes a sea gate valve 110 and a support rod 120. The sea gate valve 110 is installed on the bottom plate of the ship to install the launching and retracting device. The support rod 120 reinforces and fixes the bracket 10. The launching and retracting device is connected to the bottom plate of the ship through the flange on the sea gate valve 110, and the bracket 10 is connected and fixed to the hull structure through the support rod 120, which further improves the installation strength of the measuring device 24. When the system issues a lifting command, the lifting rod 23 equipped with the measuring device 24 rises. After the lifting rod 23 rises to the predetermined position, the sea gate valve 110 closes. An electric gate valve actuator is provided on the side of the sea gate valve 110, which drives the sea gate valve 110 to realize the remote automatic opening and closing of the valve.
[0038] Combination Figures 1 to 4 As shown, the bracket 10 in this embodiment includes an upper cover plate 11, a lower cover plate 12, and a connecting frame 13. There are several connecting frames 13 that connect the upper cover plate 11 and the lower cover plate 12. The upper cover plate 11 and the lower cover plate 12 are arranged in parallel. The drive unit 20 includes a driver 21, a transmission screw 22, a lifting rod 23, and a measuring device 24. The driver 21 is mounted on the bracket 10. The transmission screw 22 is driven by the driver 21. The lifting rod 23 is connected to the transmission screw 22 through a guide frame 40. When the transmission screw 22 rotates, the guide frame 40 drives the lifting rod 23 to move along the length direction of the transmission screw 22. The measuring device 24 is mounted at the end of the lifting rod 23. When it is necessary to retract or extend the measuring device 24, the driver 21 drives the transmission screw 22, and the lifting rod 23 moves along the length direction of the transmission screw 22. The guide frame 40 guides the movement of the lifting rod 23, and the lifting rod 23 drives the measuring device 24 to retract or extend.
[0039] In this embodiment, there are two transmission screws 22, and two screw nuts 80 are provided on the guide frame 40. The screw nuts 80 cooperate with the transmission screws 22. When the transmission screws 22 rotate, the screw nuts 80 drive the guide frame 40 to move. In this embodiment, the two transmission screws 22 and the two screw nuts 80 are threadedly engaged. When the transmission screws 22 rotate, the screw nuts 80 will move along the length direction of the transmission screws 22, causing the guide frame 40 to move along the length direction of the transmission screws 22, thereby guiding the movement of the lifting rod 23.
[0040] Furthermore, to ensure that the two lead screws 22 rotate synchronously, the driver 21 in this embodiment is mounted on the upper cover plate 11. The upper cover plate 11 is provided with a reducer 50 and a steering gear 60. There are two reducers 50, which are connected to each other by the steering gear 60. The driver 21 is a servo motor and is connected to one of the reducers 50. After the driver 21 is started, the two reducers 50 are synchronously controlled through the steering gear 60. The lead screws 22 are connected to the two reducers 50 respectively to ensure the synchronous drive of the two lead screws 22.
[0041] Specifically, in this embodiment, the driver 21 is a servo motor, which adopts a closed-loop control system and has the advantages of high precision, large speed ratio, strong load resistance and smooth operation. The two steering gears 60 are connected by an elastic coupling, which has the functions of compensating for radial, angular and axial clearance and vibration reduction. The reducer 50 reduces the output of the driver 21 and increases the torque to ensure the stable operation of the transmission screw 22.
[0042] In this embodiment, a guide rail 70 is provided on a connecting frame 13. The guide rail 70 cooperates with the guide frame 40 to guide the movement of the guide frame 40. In this embodiment, the guide rail 70 is installed on the connecting frame 13, which can guide the guide frame 40, so that the guide frame 40 moves stably along the length direction of the transmission screw 22, thereby improving the movement stability of the guide frame 40.
[0043] like Figure 1 As shown, the maintenance compartment 30 in this embodiment is located below the support 10. The maintenance compartment 30 includes a compartment 31 and a maintenance door 32. The lifting rod 23 is located inside the compartment 31 to facilitate the maintenance of the measuring equipment 24. A sealed chamber 90 is provided inside the support 10. The sealed chamber 90 is filled with lubricating oil to lubricate the lifting rod 23. The presence of the maintenance compartment 30 facilitates the routine maintenance and repair of the measuring equipment 24 inside the ship's cabin. The presence of the sealed chamber 90 ensures that the outer wall of the lifting rod 23 is always lubricated during the raising and lowering of the measuring equipment 24, and the sealed chamber 90 can effectively prevent seawater from leaking into the ship's cabin.
[0044] In this embodiment, an electric lubricating grease pump 100 is provided on the bracket 10 to introduce lubricating oil into the sealed chamber 90. It adopts a forced lubrication method to complete the automatic quantitative supply of lubricating grease to the lifting rod 23 and the sealed chamber 90.
[0045] In actual use, when the measuring device 24 needs to be retracted or extended, the driver 21 drives the two transmission screws 22, the lifting rod 23 moves along the length of the transmission screws 22, and the guide frame 40 guides the movement of the lifting rod 23. The lifting rod 23 drives the measuring device 24 to retract or extend.
[0046] In summary, the marine electric launch and recovery device of this embodiment has a compact overall design, making full use of the cabin and reducing the space occupied by the cabin. It also has good wind and wave resistance, a high degree of automation, and uses all-electric drive as a clean energy source. Electricity is directly driven, avoiding power conversion, resulting in high drive efficiency and reduced energy consumption. It is equipped with a maintenance cabin 30, which facilitates daily inspection and maintenance of the measuring equipment 24 in the cabin. Furthermore, the design of a sealed cabin 90 and a sea passage valve 110 ensures that the measuring equipment 24 is always in a lubricated state during the launch and recovery process, effectively preventing seawater leakage and ensuring stable operation of the equipment and navigation safety.
