Description

Technical Field

[0001] The invention belongs to the technical field of submersibles, and in particular relates to a submersible signal float device. Background Art

[0002] Signal buoys are essential for underwater communication and monitoring, particularly in submersibles. Existing signal buoys typically use a winch to reel in the cable connected to the signal buoy. This requires a dedicated container to house the signal buoy and additional space for the winch, which takes up considerable space. Furthermore, existing submersibles often design the winch smaller to minimize its size. While this approach saves space, it significantly reduces the length of the cable that can be wound, limiting the submersible's ability to communicate. Summary of the Invention

DETAILED DESCRIPTION

[0027] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this solution.

[0028] Example 1

[0029] like Figures 1 to 2 As shown, this embodiment designs a submersible signal float device, which includes an outer cylinder 1, an inner cylinder 3, a cable 4, a signal float 2 and other components.

[0030] The inner cylinder 3 is a hollow cylindrical structure, rotatably disposed within the outer cylinder 1. The inner cylinder 3 is driven by a winding motor 7. When the inner cylinder 3 rotates under the control of the winding motor 7, the cable 4 is reeled onto the inner cylinder 3, thereby retracting the cable 4. The signal float 2 is disposed within the inner cylinder 3 and has a top opening at the top of the inner cylinder 3. When the cable 4 is unwound, the signal float 2 can rise from the top opening of the inner cylinder 3. Upon surfacing, the submersible can communicate with the outside world through the signal sending and receiving devices within the signal float 2.

[0031] In the above structure, the inner cylinder 3 serves as both a storage container for the signal float 2 and a winding medium for the cable 4. The signal float 2 is accommodated within the cavity within the inner cylinder 3, optimizing space utilization and reducing the overall volume of the signal float 2 device, thus conserving installation space within the submersible. Furthermore, since the cable 4 can be wound around the outside of the inner cylinder 3, and the volume of the inner cylinder 3 is larger than that of a conventional winch, the length of the wound cable 4 is greater when the same number of layers of cable 4 are wound, thereby reducing the limitation of the cable 4 length on the submersible's underwater diving depth.

[0032] The inner wall of the outer cylinder 1 is provided with a vertical groove. The outer cylinder 1 can be an entire cylindrical structure. The groove wall of the vertical groove is a separate outward protrusion of the outer cylinder 1, and the vertical groove is connected to the cylindrical cavity of the outer cylinder 1. A wire slide 51 is installed in the vertical groove and can be moved up and down. The wire slide 51 can be equipped with a wire ring or wire roller. The wire ring or wire roller moves up and down with the wire slide 51 to facilitate the spiral winding of the cable 4 onto the inner cylinder 3.

[0033] One end of the cable 4 is connected to the signal float 2. The other end of the cable 4 passes through the bottom of the inner cylinder 3, through the wire loop on the wire slide 51, and is wrapped around the outside of the inner cylinder 3. When the inner cylinder 3 rotates in the forward direction, it continuously wraps around the cable 4, which in turn pulls the signal float 2 into the inner cylinder 3. When the inner cylinder 3 rotates in the reverse direction, the inner cylinder 3 releases the wrapped cable 4, and the signal float 2, under the action of buoyancy, continuously pulls the cable 4 out until the signal float 2 floats to the surface.

[0034] The vertical slot is equipped with a wire guide 5, which includes a screw rod 52, a screw motor 53, and the wire slide 51. The screw rod 52 is rotatably arranged in the vertical slot and is controlled by the screw motor 53. The wire slide 51 is threadedly connected to the screw rod 52. When the screw rod 52 rotates forward or backward, it can drive the screw rod 52 to rotate synchronously, thereby controlling the wire slide 51 to slide upward or downward, so that the cable 4 can be wound onto different positions of the inner cylinder 3.

[0035] In the structure of this embodiment, due to the structural form of the outer cylinder 1 and the inner cylinder 3, the signal float 2 device can form an assembled integral structure, which is convenient for modular installation and disassembly and reduces the difficulty of maintenance and replacement.

[0036] Example 2

[0037] like Figure 3 As shown, based on the structure of Example 1, in order to realize the transmission between the winding motor 7 and the inner cylinder 3, a transmission mechanism 8 is provided at the bottom of the outer cylinder 1, and the winding motor 7 can transmit the transmission to the inner cylinder 3 through the transmission mechanism 8.

[0038] Specifically: the transmission mechanism 8 includes a first gear 81, a first pulley 82, a belt 83, a second gear 84 and a second pulley 85; the first gear 81 is coaxially fixedly connected to the first pulley 82, the second gear 84 and the second pulley 85 are coaxially fixedly connected, and the belt 83 is connected between the first pulley 82 and the second pulley 85; the gear ring 31 provided at the bottom of the inner cylinder 3 is engaged with the first gear 81, and when the gear on the output shaft of the winding motor 7 is engaged with the second gear 84, the inner cylinder 3 is transmitted.

[0039] Due to waves, currents, and vibrations of the signal float 2, the signal float 2 and cable 4 may exert instantaneous and intense tension on the inner cylinder 3 during use. If the transmission mechanism 8 utilizes only gears for transmission, the instantaneous tension of the cable 4 could easily cause a sudden increase in the load on the winding motor 7, potentially damaging the winding motor 7 or the gears. However, because the belt 83 transmits power through friction, when the instantaneous tension of the cable 4 increases, the belt 83 can buffer it by slipping against the first pulley 82 or the second pulley 85, thereby effectively protecting the gears and the winding motor 7.

[0040] A bottom mounting platform 11 is fixedly provided at the bottom of the outer cylinder 1, and a translation mechanism 10 is provided on the bottom mounting platform 11. The translation mechanism 10 includes a translation electric cylinder 101 and an L-shaped frame 102; the L-shaped frame 102 is slidably provided on the bottom mounting platform 11 and is controlled to move by the translation electric cylinder 101; the winding motor 7 is fixed on the L-shaped frame 102 and moves with it, so that the gear on the output shaft of the winding motor 7 engages with or disengages from the second gear 84.

[0041] When the signal float 2 rises, if the cable 4 is not fully released, the signal float 2 will rise and fall due to the fluctuations of the waves, and the cable 4 will continuously transmit tension to the inner cylinder 3, causing the inner cylinder 3 to generate a continuously changing rotational torque. The rotational force of the inner cylinder 3 is transmitted to the winding motor 7, which can easily cause the load of the winding motor 7 to fluctuate, affecting its service life and operational stability. The translation mechanism 10 can disengage the winding motor 7 from the transmission mechanism 8, thereby preventing the winding motor 7 from being subjected to the constantly changing load and shortening its service life.

[0042] Example 3

[0043] like Figure 4 and Figure 5 As shown, based on the structure of Example 1, a damper 9 is further provided on the L-shaped frame 102, and the damper 9 moves with the L-shaped frame 102. The third gear 95 connected to the central axis 93 of the damper 9 and the gear on the output shaft of the winding motor 7 can alternately engage or disengage with the second gear 84.

[0044] The damper 9 includes a cylindrical shell 91, on the interior of which are provided a plurality of annular damping plates 92, which are arranged in a vertical direction and spaced apart from each other; a sector-shaped plate 94 is provided on the radially outer side of the central axis 93, and the outer end of the sector-shaped plate 94 is inserted between adjacent damping plates 92 and in frictional contact with the damping plates 92.

[0045] The segments 94 comprise multiple layers, each containing two to four segments 94. The segments 94 are arranged in a circular pattern. A U-shaped elastic member connects the segments 94 to the central axis 93. When the cable 4 experiences instantaneous tension, the segments 94 radially expand under the action of centrifugal force, increasing the contact area with the damping plate 92 and thereby increasing the resistance of the damper 9. The U-shaped elastic member controls the return of the segments 94, ensuring a more balanced resistance to the rotation of the inner cylinder 3.

[0046] When the signal float 2 floats to the surface of the water, while a part of the cable 4 is still wrapped around the inner cylinder 3, the translation electric cylinder 101 controls the L-shaped frame 102 to move, so that the winding motor 7 and the damper 9 move synchronously, so that the third gear 95 and the second gear 84 are engaged with each other, and the gear on the output shaft of the winding motor 7 is disengaged from the second gear 84. At this time, when the cable 4 is subjected to instantaneous tension due to the fluctuation of the waves and the rotational torque of the inner cylinder 3 exceeds the threshold, the damper 9 can rotate and use the friction between the damping plate 92 and the fan-shaped plate 94 to relieve the instantaneous tension, thereby protecting the cable 4 from being broken by the instantaneous tension, while also protecting the stability and safety of the inner cylinder 3 and the winding motor 7.

[0047] The above embodiments are merely examples for the purpose of illustrating the present invention clearly and are not intended to limit the embodiments. It is not necessary and impossible to enumerate all embodiments here. Obvious changes or modifications derived therefrom are still within the scope of protection of this technology.
