Description

Technical Field

[0001] The invention relates to an underwater winch cable storage and discharge device, belonging to the field of underwater intelligent equipment. Background Art

[0002] The storage and cable arrangement device (SAD), a key component of a winch, is primarily used to neatly store and orderly discharge cable during cable retraction and release. During retraction, it winds the cable neatly around the winch drum, preventing tangles and knots. During payout, it ensures the cable is released at a stable speed and angle.

[0003] Current storage and discharge cable systems are complex to implement, typically requiring additional components and sensors, resulting in high costs and significant control difficulties. Furthermore, traditional underwater winch storage and discharge cables require specialized personnel for operation.

[0004] For example, Chinese patent CN114751327A, titled "Automatic Deployment and Retrieval Winch for Ocean Buoys," utilizes an incremental encoder installed on the cable-laying mechanism and limit switches on both sides of the winch to achieve orderly cable retraction and deployment. However, this method has drawbacks, such as requiring real-time tracking of position and limit switch signals, making control more difficult.

[0005] Chinese patent CN116534753A, titled "Automatic Cable Retraction and Deployment Winch for Unmanned Arrays," achieves automatic cable arrangement by combining the force exerted by the cable, which is always perpendicular to the winch drum, on a torque sensor and the angular velocity signal from the lead screw. However, this method has drawbacks such as requiring additional torque and angular velocity sensors, which increases operating costs. Summary of the Invention

[0006] The technical problem solved by the present invention is: to overcome the limitation that traditional underwater winch cable storage and discharge requires professional personnel to operate, and to provide an underwater winch cable storage and discharge device to achieve synchronous displacement of the guide wheel assembly and the drum cable of the cable discharge device, thereby reducing the equipment assembly time and operation difficulty.

[0007] The technical solution of the present invention is:

[0008] An underwater winch cable storage and discharge device comprises: an upper end plate, a lower end plate, a fixed bearing sleeve on a drum, a fixed flange on a drum, an upper end plate of the drum, a drum core, a lower end plate of the drum, a fixed flange below the drum, a fixed bearing sleeve below the drum, a fixed flange above a lead screw, a guide wheel assembly, a bidirectional lead screw, an optical axis, a fixed sleeve for the optical axis, a fixed flange below the lead screw, a cable storage driving wheel, a cable storage driven wheel, and a cable discharge driven wheel;

[0009] The upper end plate and the lower end plate of the reel are fixed to the upper and lower ends of the reel core respectively. The upper end of the reel core is also fixed to one end of the upper end plate through the upper fixing flange of the reel and the upper fixed bearing sleeve of the reel. The upper end of the reel core is also fixed to one end of the lower end plate through the lower fixing flange of the reel and the lower fixed bearing sleeve of the reel.

[0010] After the bidirectional lead screw passes through the guide wheel assembly, it is fixedly connected to the other end of the upper end plate and the other end of the lower end plate through the lead screw upper fixing flange and the lead screw lower fixing flange respectively; the optical axis and the bidirectional lead screw are arranged in parallel, and after the optical axis passes through the guide wheel assembly, the two ends of the optical axis are fixed to the other end of the upper end plate and the other end of the lower end plate through the optical axis fixing sleeves;

[0011] The cable storage driving wheel and the cable arrangement driven wheel are coaxially and parallelly arranged on the central axis of the fixed flange on the drum, and the cable storage driven wheel is arranged on the fixed flange on the screw.

[0012] Furthermore, the cable storage and discharge device acts on the cable discharge driven wheel 21 through external power to make it rotate, thereby driving the drum core 7 to rotate, so that the cable 6 passes through the guide wheel assembly 12 and is wound on the drum core 7 between the drum upper end plate 5 and the drum lower end plate 8.

[0013] Furthermore, it also includes a chain 17, which drives the cable storage driving wheel 19 to rotate through the rotation of the drum core 7, and the cable storage driving wheel 19 drives the cable storage driven wheel 20 through the chain 17. The cable storage driven wheel 20 drives the bidirectional screw 13 to rotate, so that the bidirectional screw 13 drives the guide wheel assembly 13 to reciprocate up and down.

[0014] Furthermore, it also includes a tensioning wheel for tensioning the chain.

[0015] Furthermore, the cable winding displacement and the guide wheel assembly operate synchronously.

[0016] Furthermore, let p = (2n + 1) / 2i, where p is the number of screw cycles, n is the number of cable turns per layer, and i is the transmission ratio between the cable storage driving wheel and the cable storage driven wheel;

[0017] Furthermore, when p=(2n+1) / 2i, the cable will complete the upper half of the (2n+1) / 2th circle along the current layer when it is under force, and will wind the lower half of the (2n+2) / 2th circle when the guide wheel assembly moves in the opposite direction. At this time, the cable winding displacement and the guide wheel assembly operate synchronously.

[0018] The beneficial effects of the present invention compared with the prior art are:

[0019] (1) The present invention proposes an underwater winch cable storage and discharge device, which can realize the synchronous displacement of the guide wheel assembly and the drum cable of the cable discharge device, ensure that the cable storage assembly is neatly and densely discharged, thereby improving the space utilization rate of underwater equipment and reducing equipment assembly time.

[0020] (2) The method for designing the synchronous displacement of the guide wheel assembly and the drum cable of the cable storage and discharge device proposed in the present invention can reduce the axial force of the guide assembly, thereby reducing the design difficulty of the cable storage and discharge device.

[0024] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, an underwater winch cable storage and discharge device proposed in the present invention includes an upper end plate 1, a lower end plate 2, a fixed bearing sleeve 3 on the drum, a fixed flange 4 on the drum, an upper end plate 5 on the drum, a cable 6, a drum core 7, a lower end plate 8 on the drum, a fixed flange 9 on the drum, a fixed bearing sleeve 10 on the drum, a fixed flange 11 on the lead screw, a guide wheel assembly 12, a bidirectional lead screw 13, an optical axis 14, a fixed sleeve 15 for the optical axis, a fixed flange 16 on the lead screw, a chain 17, a tensioning wheel 18, a cable storage driving wheel 19, a cable storage driven wheel 20, and a cable discharge driven wheel 21.

[0026] Among them, the upper end plate 5 of the reel and the lower end plate 8 of the reel are fixed to the upper and lower ends of the reel core 7 respectively. The upper end of the reel core 7 is also fixed to one end of the upper end plate 1 through the upper fixing flange 4 of the reel and the upper fixed bearing sleeve 3 of the reel. The upper end of the reel core 7 is also fixed to one end of the lower end plate 2 through the lower fixing flange 9 of the reel and the lower fixed bearing sleeve 10 of the reel.

[0027] After passing through the guide wheel assembly 12, the bidirectional lead screw 13 is fixedly connected to the other end of the upper end plate 1 and the other end of the lower end plate 2 through the lead screw upper fixing flange 11 and the lead screw lower fixing flange 16 respectively; the optical axis 14 and the bidirectional lead screw 13 are arranged in parallel. After passing through the guide wheel assembly 12, the two ends of the optical axis 14 are fixed to the other end of the upper end plate 1 and the other end of the lower end plate 2 through the optical axis fixing sleeves 15;

[0028] The cable storage driving wheel 19 and the cable arrangement driven wheel 21 are coaxially and parallelly arranged on the central axis of the fixed flange 4 on the drum, and the cable storage driven wheel 20 is arranged on the fixed flange 11 on the screw.

[0029] Working principle:

[0030] The cable storage and discharge device acts on the cable discharge driven wheel 21 through external power to make it rotate, thereby driving the drum core 7 to rotate, so that the cable 6 passes through the guide wheel assembly 12 and is wound on the drum core 7 between the drum upper end plate 5 and the drum lower end plate 8.

[0031] The cable storage driving wheel 19 is driven by the rotation of the winding drum core 7, and the cable storage driving wheel 19 drives the cable storage driven wheel 20 through the chain 17. The cable storage driven wheel 20 drives the bidirectional screw 13 to rotate, thereby driving the bidirectional screw 13 to reciprocate the guide wheel assembly 13 up and down. The tensioning wheel 18 is used to tension the chain 17.

[0032] Principle analysis:

[0033] In the present invention, when the cable 7 of the cable storage and discharge device is under stress, it will complete the upper half of the n+1th circle along the current layer (p=n / i, p is the number of screw cycles, n is the number of cable turns per layer, and i is the transmission ratio of the cable storage active wheel 19 and the cable storage driven wheel 20). However, at this time, the guide wheel assembly 12 has already traveled 1 / 2i cycles in the opposite direction, so the cable winding displacement and the guide wheel assembly displacement have "lost step", and the loss of step displacement between the two is m / 2i, where m is the number of cable layers. Figure 3 shown.

[0034] In order to solve the "out-of-step phenomenon" between the winding displacement of the cable 6 and the guide wheel assembly 12, the cable storage and discharge device proposed in the present invention sets p = (2n+1) / 2i. When the cable 6 is under force, it will complete the upper half of the (2n+1) / 2th circle along the current layer, and the guide wheel assembly 12 will wind the lower half of the (2n+2) / 2th circle when moving in the opposite direction. At this time, the winding displacement of the cable 6 and the guide wheel assembly 12 operate synchronously.
