Description

Technical Field

[0001] This invention relates to the field of winch technology, and in particular to a dual-drive winch for the deployment and retrieval of tethering cables for airships. Background Technology

[0002] Aerostats are aircraft that are lighter than air and rely on atmospheric buoyancy to take off. When performing retrieval or mooring operations on the ground, tethers and winches are typically used to provide ground restraints to facilitate ascent, descent, and transfer.

[0003] In the existing technology, the winch of the airship is usually equipped with a single drive mechanism. This drive mechanism has high requirements for the electrical control system. If the winch loses power or the motor fails during operation, the airship will not be able to be launched smoothly, resulting in poor reliability. Summary of the Invention

Both the first rotating shaft and the second rotating shaft are rotatably connected to the housing. The first rotating shaft is drive-connected to the second rotating shaft so that the second drive motor drives the first rotating shaft to rotate. The first rotating shaft is drive-connected to the hoisting module.

[0007] According to the present invention, a dual-drive winch device for launching and retrieving tethering of an airship is provided, wherein a first gear is provided on the first rotating shaft and a second gear is provided on the second rotating shaft, and the first gear meshes with the second gear.

[0008] According to the present invention, the dual-drive winch device for launching and retrieving tethering of an airship is provided, wherein the first clutch is a normally closed clutch and the second clutch is a normally open clutch.

The cable arrangement assembly includes a bidirectional lead screw, a slide block, and a cable arrangement pulley. The bidirectional lead screw is parallel to and spaced apart from the drum. The bidirectional lead screw is rotatably mounted on the first mounting base and is drivenly connected to the drum so that the drum drives the bidirectional lead screw to rotate. The slide block is mounted on the bidirectional lead screw and can reciprocate along the length direction of the bidirectional lead screw. The cable arrangement pulley is rotatably mounted on the slide block.

[0011] According to the dual-drive winch device for launching and retrieving tethering cables for an airship provided by the present invention, the winch module further includes a worm gear reducer, the first rotating shaft is drivenly connected to the input end of the worm gear reducer, and the output end of the worm gear reducer is drivenly connected to the drum.

[0012] The dual-drive winch device for launching and retrieving tethering of an airship provided by the present invention further includes a tension length measurement module. The tension length measurement module includes a second mounting base, a pin-type load cell, a tension measuring wheel, a length counting wheel, and a length encoder. The second mounting base is disposed on the frame. The pin-type load cell is rotatably disposed on the second mounting base. The tension measuring wheel is sleeved on the pin-type load cell. The length counting wheel is rotatably disposed on the second mounting base. The outer edge of the length counting wheel meshes with the outer edge of the tension measuring wheel.

[0013] According to the dual-drive winch device for launching and retrieving tethering of an airship provided by the present invention, a rocker arm is provided on the second mounting base, the length measuring wheel is rotatably disposed on the rocker arm, and a tension spring is provided between the rocker arm and the second mounting base to press the length measuring wheel against the tension measuring wheel.

[0017] The present invention provides a dual-drive winch device for tethering and deployment of airships. By setting up a drive module, when neither the first drive motor nor the second drive motor in the drive module malfunctions, or when the second drive motor malfunctions, the first drive motor can drive the first rotating shaft to rotate via the first clutch, thereby driving the winch module to rotate and realize tethering and deployment. When the first drive motor malfunctions, the second drive motor can drive the second rotating shaft to rotate via the second clutch.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0039] The following is combined Figures 1 to 12 This invention describes a dual-drive winch device for the deployment and retrieval of tethers for airships.

[0040] The present invention provides a dual-drive winch device for the deployment and retrieval of tethers for airships, comprising: a frame 100, a drive module 200 and a winch module 300, wherein the drive module 200 and the winch module 300 are both disposed on the frame 100.

[0041] The drive module 200 includes a housing 210, a first drive motor 220, a second drive motor 230, a first clutch 240, a second clutch 250, a first rotating shaft 260, and a second rotating shaft 270. The output shaft of the first drive motor 220, the first clutch 240, and the first rotating shaft 260 are connected in sequence. The output shaft of the second drive motor 230, the second clutch 250, and the second rotating shaft 270 are connected in sequence. Both the first rotating shaft 260 and the second rotating shaft 270 are rotatably connected to the housing 210. The first rotating shaft 260 is driveably connected to the second rotating shaft 270 so that the second drive motor 230 drives the first rotating shaft 260 to rotate. The first rotating shaft 260 is driveably connected to the hoisting module 300.

[0042] The dual-drive winch device for tether deployment and retrieval of airships provided by this invention, through the setting of a drive module 200, allows the first drive motor 220 to drive the first rotating shaft 260 to rotate via the first clutch 240 and drive the winch module 300 to rotate, thereby realizing the deployment and retrieval of the tether, when both the first drive motor 220 and the second drive motor 230 in the drive module 200 are functioning normally or when the second drive motor 230 is malfunctioning. This enables the tether deployment and retrieval. When the first drive motor 220 malfunctions, the second drive motor 230 can drive the second rotating shaft 270 to rotate via the second clutch 250. Since the second rotating shaft 270 is connected to the first rotating shaft 260, the rotation of the second rotating shaft 270 can drive the first rotating shaft 260 to rotate, thereby further driving the winch module 300 to rotate, so that the winch module 300 can normally deploy and retrieval the tether, ensuring the smooth deployment of the airship and improving the reliability of the airship deployment.

[0043] Specifically, in this embodiment, the frame 100 is a rectangular frame structure. The frame 100 provides installation space and support for the drive module 200, the hoisting module 300, and other components (such as the tension length measurement module 400, the tethering guide module 500, the power supply module 600, and the electrical control module 700 described below). The shape of the frame 100 is not limited to a rectangular frame structure; other structures can be used depending on actual needs.

[0044] The drive module 200 drives the hoist module 300 to operate, enabling the deployment and retraction of the tether. The drive module 200 includes a housing 210, a first drive motor 220, a second drive motor 230, a first clutch 240, a second clutch 250, a first rotating shaft 260, and a second rotating shaft 270. The first drive motor 220 is the primary motor, and the second drive motor 230 is the backup motor. The first drive motor 220 can establish or disengage a transmission connection with the first rotating shaft 260 via the first clutch 240, and the second drive motor 230 can establish or disengage a transmission connection with the second rotating shaft 270 via the second clutch 250. The first rotating shaft 260 and the second rotating shaft 270 are connected, allowing them to drive each other, enabling either the first drive motor 220 or the second drive motor 230 to drive the first rotating shaft 260 to rotate. Both the first clutch 240 and the second clutch 250 are electromagnetic clutches, offering fast response and simple control.

[0045] The winch module 300 is used to store or release the tether. The first rotating shaft 260 is connected to the winch module 300 for transmission, so that the rotation of the first rotating shaft 260 drives the winch module 300 to operate. The winch module 300 can be in the form of a drum or a winch. Both the drum 321 and the winch are cylindrical devices that can tighten and loosen the tether by rotation.

[0046] It should be noted that the first rotating shaft 260 can be directly connected to the hoisting module 300, or it can be connected through a transmission mechanism / device. For example, when the first drive motor 220 and the second drive motor 230 are direct drive motors, the first rotating shaft 260 and the hoisting module 300 can be connected through a transmission mechanism / device to limit the operating speed of the hoisting module 300 within a preset range. When both the first drive motor 220 and the second drive motor 230 are geared motors, the first rotating shaft 260 and the hoisting module 300 can be directly connected.

[0047] See Figure 3 and Figure 4As shown, according to some embodiments of the present invention, a first gear 280 is provided on a first rotating shaft 260, and a second gear 290 is provided on a second rotating shaft 270, wherein the first gear 280 and the second gear 290 mesh.

[0048] By setting a first gear 280 on the first rotating shaft 260 and a second gear 290 on the second rotating shaft 270, the first rotating shaft 260 and the second rotating shaft 270 are configured as a transmission connection. The transmission can be achieved by the meshing of the first gear 280 and the second gear 290. The structure is simple, the transmission accuracy is high, and the stability is strong.

[0049] It should be noted that the number of teeth of the first gear 280 and the second gear 290 can be set according to actual needs. For example, the number of teeth of the first gear 280 can be greater than the number of teeth of the second gear 290, the number of teeth of the first gear 280 can be equal to the number of teeth of the second gear 290, or the number of teeth of the first gear 280 can be less than the number of teeth of the second gear 290.

[0050] In some embodiments, the first rotating shaft 260 and the second rotating shaft 270 can also be configured for transmission connection through other transmission mechanisms, such as chain drive or belt drive.

[0051] According to some embodiments of the present invention, the first clutch 240 is a normally closed clutch and the second clutch 250 is a normally open clutch.

[0052] Since the first drive motor 220 is the main motor and the second drive motor 230 is the backup motor, by setting the first clutch 240 as a normally closed clutch and the second clutch 250 as a normally open clutch, the automatic switching between the main motor and the backup motor can be realized, thereby improving the reliability and safety of the hoisting device.

[0053] Specifically, under normal operating conditions, the first clutch 240 remains closed, the first drive motor 220 is connected to the first shaft 260 and provides power to the hoisting module 300; simultaneously, the second clutch 250 remains open, and the second drive motor 230 does not participate in operation. If the first drive motor 220 malfunctions or needs to be stopped, the first clutch 240 can be disengaged and the second clutch 250 activated, allowing the second drive motor 230 to be connected to the first shaft 260 via the second shaft 270, taking over the power output and ensuring uninterrupted operation of the hoisting device.

[0054] See Figure 5 and Figure 6As shown, according to some embodiments of the present invention, the hoisting module 300 includes a first mounting base 310, a drum assembly 320, and a cable arrangement assembly 330; the drum assembly 320 includes a drum 321, which is rotatably disposed on the first mounting base 310; the cable arrangement assembly 330 includes a bidirectional lead screw 331, a slide block 332, and a cable arrangement pulley 333; the bidirectional lead screw 331 is parallel to and spaced apart from the drum 321; the bidirectional lead screw 331 is rotatably disposed on the first mounting base 310; the bidirectional lead screw 331 is connected to the drum 321 for transmission, so as to drive the bidirectional lead screw 331 to rotate through the drum 321; the slide block 332 is disposed on the bidirectional lead screw 331 and can reciprocate along the length direction of the bidirectional lead screw 331; and the cable arrangement pulley 333 is rotatably disposed on the slide block 332.

[0055] By configuring the winch module 300 in a configuration that combines the drum assembly 320 and the cable arrangement assembly 330, more precise and efficient cable arrangement can be achieved. The bidirectional lead screw 331 is arranged parallel to the drum 321, ensuring stable power transmission. Simultaneously, the bidirectional lead screw 331's drive connection to the drum 321 allows the slide block 332 to reciprocate along the length of the bidirectional lead screw 331, improving the flexibility and adaptability of cable arrangement. The rotating cable arrangement pulley 333 ensures more uniform and smooth cable arrangement, reducing the risk of wear and malfunction.

[0056] Specifically, in this embodiment, both the drum 321 and the bidirectional lead screw 331 are horizontally mounted on the first mounting base 310, and the stroke of the bidirectional lead screw 331 is consistent with the length of the drum 321. One end of the drum 321 is provided with a drum shaft 334, which rotates synchronously with the drum 321 and is connected to the bidirectional lead screw 331 via a belt drive mechanism. Of course, in some embodiments, the drum shaft 334 can also be connected to the bidirectional lead screw 331 via gear drive or chain drive.

[0057] See Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the hoisting module 300 further includes a worm gear reducer 340, the first rotating shaft 260 is drivenly connected to the input end of the worm gear reducer 340, and the output end of the worm gear reducer 340 is drivenly connected to the drum 321.

[0058] By installing a worm gear reducer 340 between the first shaft 260 and the drum 321, the transmission speed can be effectively reduced and the output torque increased, providing greater driving force to drive the drum 321. The structural characteristics of the worm gear allow for switching of the output direction of the driving force, thereby improving the integration and compactness of the winch device. Furthermore, the worm gear reducer 340 is designed with a self-locking function to prevent reverse rotation of the winch device when it stops, further improving stability and safety.

[0059] See Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, the dual-drive winch device for launching and retrieving the tether of an airship further includes a tension length measurement module 400. The tension length measurement module 400 includes a second mounting base 410, a pin-type load cell 420, a tension measuring wheel 430, a length counting wheel 440, and a length encoder 450. The second mounting base 410 is disposed on the frame 100. The pin-type load cell 420 is rotatably disposed on the second mounting base 410. The tension measuring wheel 430 is sleeved on the pin-type load cell 420. The length counting wheel 440 is rotatably disposed on the second mounting base 410. The outer edge of the length counting wheel 440 meshes with the outer edge of the tension measuring wheel 430.

[0060] By setting up the tension-length measurement module 400, the tension and length of the tether wound on the drum 321 can be measured and displayed, thereby achieving effective monitoring and control of the tether status of the airship. By meshing the tension measuring wheel 430 and the length measuring wheel 440, the tension and length of the tether can be measured synchronously, thus enabling more accurate monitoring of the tether status.

[0061] Specifically, the principle of tension measurement is to install a pin-type load cell 420 inside the tension measuring wheel 430, which serves as a support shaft for the tension measuring wheel 430. A tethering cable passes through the tension measuring wheel 430. When the tethering cable is under stress, the pin-type load cell 420 deforms. The actual tension on the tethering cable is calculated by the wrap angle formed by the tethering cable passing through the tension measuring wheel 430. The principle of length measurement is to install a length counting wheel 440 on top of the tension measuring wheel 430. The outer rim of the length counting wheel 440 is typically made of rubber, which meshes with the outer edge of the tension measuring wheel 430. When the tethering cable passes through the tension measuring wheel 430, the cable causes the tension measuring wheel 430 to rotate. The length counting wheel 440 rotates under the influence of the tension measuring wheel 430. The length counting wheel 440 is mounted on a length encoder 450. The rotation of the length counting wheel 440 completes the rotation of the length encoder 450, thus completing the length measurement.

[0062] See Figure 7 and Figure 8 As shown, according to some embodiments of the present invention, a rocker arm 460 is provided on the second mounting base 410, and a length measuring wheel 440 is rotatably disposed on the rocker arm 460. A tension spring 470 is provided between the rocker arm 460 and the second mounting base 410 to press the length measuring wheel 440 against the tension measuring wheel 430.

[0063] By mounting a rocker arm 460 on the second mounting base 410 and rotatably mounting the length-counting wheel 440 on the rocker arm 460, a tension spring 470 located between the rocker arm 460 and the second mounting base 410 can pull the rocker arm 460 downwards, pressing the length-counting wheel 440 tightly against the tension measuring wheel 430. This prevents gaps or slippage between the length-counting wheel 440 and the tension measuring wheel 430, ensuring a tight engagement between them at all times. This avoids measurement errors caused by poor contact and ensures that the length-counting wheel 440 accurately records the length of the tether throughout the entire deployment and retraction process. Furthermore, the elasticity of the tension spring 470 allows the length-counting wheel 440 to adjust its pressure in real time according to changes in the tension measuring wheel 430, providing a stable contact force, enhancing the measurement accuracy and reliability of the system, while reducing mechanical wear and extending the service life of the equipment.

[0064] Specifically, see Figure 7 As shown, the second mounting base 410 is provided with a mounting shaft 480, one end of the rocker arm 460 is rotatably mounted on the mounting shaft 480, and the length counting wheel 440 is rotatably mounted on the other end of the rocker arm 460. One end of the tension spring 470 is connected to the inner side wall of the second mounting base 410, and the other end is connected to the side wall of the rocker arm 460, so as to pull the rocker arm 460 down and drive the length counting wheel 440 down.

[0065] See Figure 9 and Figure 10 As shown, according to some embodiments of the present invention, the dual-drive winch device for tethering and retrieving the tether of an airship further includes a tether guide module 500. The tether guide module 500 includes a third mounting base 510, a guide wheel 520 and an upper guide wheel 530. The third mounting base 510 is rotatably mounted on the frame 100. The guide wheel 520 and the upper guide wheel 530 are both rotatably mounted on the third mounting base 510. A space for the tether to pass through is formed between the guide wheel 520 and the upper guide wheel 530.

[0066] By setting the tether guide module 500, the movement path of the tether during the winding and unwinding process can be effectively guided and controlled, ensuring that the tether is smoothly wound and unwound in the winch device.

[0067] Specifically, the tether guide module 500 fixes the guide wheel 520 and the upper guide wheel 530 to the frame 100 via the third mounting base 510, allowing them to rotate freely. This reduces the risk of tangling, misalignment, or damage to the tether during deployment and retraction. The space formed between the guide wheel 520 and the upper guide wheel 530 limits the tether, ensuring that it remains between them during deployment and retraction, preventing it from coming off.

[0068] See Figure 11As shown, according to some embodiments of the present invention, the dual-drive winch device for launching and retrieving the tether of an airship further includes a power supply module 600. The power supply module 600 includes a first power supply box and a second power supply box. The first power supply box is electrically connected to the first drive motor 220, and the second power supply box is electrically connected to the second drive motor 230.

[0069] By incorporating power supply module 600, the two drive motors of the dual-drive winch device can be ensured to receive independent and stable power, thereby achieving more reliable and efficient system operation. The first power supply box is electrically connected to the first drive motor 220, and the second power supply box is electrically connected to the second drive motor 230, allowing each motor to obtain the required power independently, avoiding system performance degradation or failure due to uneven power supply. The design of power supply module 600 ensures dual power redundancy; if one power supply box fails, the other can continue to provide power, ensuring the continuous operation of the winch device. This not only improves system stability and reliability but also enables optimized power supply management to a certain extent, enhancing the efficiency and safety of the airship tether deployment and retrieval.

[0070] Specifically, both the first and second power supply boxes are equipped with batteries and flexible support structures to support the batteries. The flexible support structures are designed to effectively absorb external vibrations and impacts, thereby preventing the batteries from being damaged or loosened due to violent movement or external forces, and ensuring the stability of the batteries within the power supply boxes.

[0071] See Figure 12 As shown, according to some embodiments of the present invention, the dual-drive winch device for launching and retrieving the tether of the airship further includes an electrical control module 700, which is disposed on the frame 100.

[0072] By setting up the electrical control module 700, it is possible to communicate with the drive module 200, hoisting module 300, tension and length measurement module 400 and power supply module 600, etc., to monitor and adjust the working status of each module in real time, so as to ensure the efficient and stable operation of the entire dual-drive hoisting device and realize the coordination and precise control between the modules.

[0073] Specifically, the electronic control module 700 includes an electronic control operation panel, a controller, a charger, and a communication interface. The controller is communicatively connected to the communication interface, the first drive motor 220, the second drive motor 230, and the motor brake. The charger is used to connect to the battery of the power supply module 600. The communication interface is used to connect to the electronic control operation panel, which includes control buttons for the first drive motor 220 and the second drive motor 230 to receive user operation commands. The controller responds to the operation commands to control the start and stop of the motors, the switching between the main and backup motors, and the braking operation of the brake. The electronic control operation panel also includes tension and length display instruments to display the current tension of the tether and the length of the rope being pulled up and released.

[0074] As can be seen from the above description of the embodiments, the dual-drive winch device for launching and retrieving tethers of airships provided by the present invention has at least the following advantages.

[0075] (1) The dual-drive winch device for tethering and releasing of airships provided by the present invention, by setting up a drive module 200, when neither the first drive motor 220 nor the second drive motor 230 in the drive module 200 malfunctions or the second drive motor 230 malfunctions, can use the first drive motor 220 to drive the first rotating shaft 260 to rotate via the first clutch 240 and drive the winch module 300 to rotate, thereby realizing the tethering and releasing. When the first drive motor 220 malfunctions, the second drive motor 230 can be used to drive the second rotating shaft 270 to rotate via the second clutch 250. Since the second rotating shaft 270 is connected to the first rotating shaft 260, the rotation of the second rotating shaft 270 can drive the first rotating shaft 260 to rotate, thereby further driving the winch module 300 to rotate, so that the winch module 300 can normally tether and release the tether, ensuring the smooth completion of the airship release and improving the reliability of the airship release.

[0076] (2) The dual-drive winch device for tethering and unwinding of airships provided by the present invention adopts a compact frame winch device structure, which is convenient for transportation and installation; the drum 321 device can be designed with rope capacity according to actual needs, which is suitable for tethering and unwinding of airships with a length of tens of meters or more, and has stronger adaptability; the cable arrangement component can ensure that the cable is neatly arranged and avoids tangling, which is particularly suitable for tethering and unwinding of airships; the tension and length measuring device can measure the tension and unwinding length of the cable in real time, which is convenient for adjusting the unwinding length according to the actual tension; it provides independent power supply and electrical control components for the two sets of drive motors, supports rapid switching, improves the reliability of the device, and ensures stable operation of the system.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
