[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Embodiment 1

[0033] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a signal float 30 release device, which is used in underwater equipment. The signal float 30 release device can control the release of the signal float 30, and the released float can float to the water surface. Specifically, the signal float 30 release device includes a base 10, a first rotating shaft 20, a second rotating shaft 40 and a signal float 30. The first rotating shaft 20 and the second rotating shaft 40 can be rotatably connected to the base 10, and the first rotating shaft 20 is fixed with a curved gear 21, and the second rotating shaft 40 is fixed with a fan gear 41. During the rotation of the second shaft 40, the fan gear 41 rotates with the second shaft 40. When the second shaft 40 rotates to a certain angle, the fan gear 41 meshes with the curved gear 21. At this time, if the second shaft 40 stops rotating, the first shaft 20 stops rotating through the meshing of the fan gear 41 and the curved gear 21, thereby locking the first shaft 20; when the second shaft 40 continues to rotate to another angle, the fan gear 41 is separated from the curved gear 21. At this time, if the second shaft 40 stops rotating, the first shaft 20 can continue to rotate through the separation of the fan gear 41 and the curved gear 21, and during the continued rotation of the first shaft 20, the curved gear 21 is always in a separated state from the fan gear 41 and does not interfere with each other, thereby unlocking the first shaft 20. In addition, a rope 22 is wound around the first rotating shaft 20, one end of the rope 22 is fixed to the first rotating shaft 20; the signal float 30 is connected to the other end of the rope 22, and the signal float 30 has buoyancy in water. When the second rotating shaft 40 is unlocked, the signal float 30 can pull the rope 22 through its own buoyancy and make the second rotating shaft 40 rotate, thereby realizing the release function of the signal float 30. When the second rotating shaft 40 is locked, the locking function of the signal float 30 is realized.

[0034] In addition, it should be noted that when it is necessary to recover the released signal float 30, the rope 22 and the signal float 30 can be recovered by rotating the first rotating shaft 20 under the condition that the curved gear 21 and the fan gear 41 are separated. When the signal float 30 is recovered to a specified distance from the first rotating shaft 20, the second rotating shaft 40 can be rotated to make the curved gear 21 and the fan gear 41 engage, thereby achieving the purpose of locking the first rotating shaft 20 and fixing the signal float 30.

[0035] Furthermore, the above-mentioned curved gear 21 can be a sector gear or a circular gear. Figure 4 As shown, when the curved gear 21 is a sector gear, the sector gear 41 can be completely separated from the curved gear 21 when it rotates to a certain angle. Figure 3 As shown, when the curved gear 21 is a circular gear, the sector gear 41 can also be completely separated from the curved gear 21 by rotating a certain angle.

[0036] like Figure 1 As shown, further, the signal float 30 release device also includes a driving mechanism 50, which is connected to the second rotating shaft 40, so that the second rotating shaft 40 is driven to rotate by the driving mechanism 50. In addition, the driving mechanism 50 can control the rotation angle of the second rotating shaft 40, thereby controlling the second rotating shaft 40 to lock or unlock.

[0037] Specifically, in this embodiment, the driving mechanism 50 includes a box body 52 and a driving float 51. The bottom of the box body 52 is fixed on the base 10, and the box body 52 can contain liquid; the driving float 51 is located in the box body 52, and the second rotating shaft 40 is at least partially located in the box body 52, and the second rotating shaft 40 is rotatably connected to the side wall of the box body 52, and the driving float 51 is circumferentially fixedly connected to the part of the second rotating shaft 40 located in the box body 52. ​​The liquid level of the liquid in the box body 52 is controlled by controlling the amount of liquid in the box body 52. ​​When the liquid level in the box body 52 rises, the driving float 51 swings upward around the second rotating shaft 40 under the action of buoyancy, and drives the second rotating shaft 40 to rotate. When the liquid level in the box body 52 decreases, the driving float 51 swings downward under the action of its own gravity, and drives the second rotating shaft 40 to rotate in the opposite direction. Since the driving float 51 is fixedly connected to the second rotating shaft 40 , when the driving float 51 moves with the liquid level, it will also drive the second rotating shaft 40 to rotate, thereby locking or unlocking the first rotating shaft 20 .

[0038] In this embodiment, the buoyancy of the driving float 51 is greater than the buoyancy of the signal float 30, so that when the curved gear 21 is meshed with the sector gear 41, the second rotating shaft 40 can remain motionless under the action of the driving float 51, thereby keeping the distance between the signal float 30 and the second rotating shaft 40 stable. The above-mentioned liquid can be water or liquids such as oil.

[0039] It should be noted that, in some other embodiments, the driving mechanism may also be a caliper, and the second rotating shaft 40 can also be driven by manually rotating the angle of the second rotating shaft 40 and locking the second rotating shaft 40 by the caliper.

[0040] In addition, in this embodiment, a connecting rod 511 is fixed to the circumferential wall of the second rotating shaft 40, and the driving float 51 is fixed to the connecting rod 511. Since the connecting rod 511 is fixed to the circumferential wall of the second rotating shaft 40, when the driving float 51 swings downward by gravity, the connecting rod 511 can increase the gravity that drives the floating ball 51 to swing downward.

[0041] Preferably, in this embodiment, both ends of the second rotating shaft 40 are rotatably sealed and connected to the side walls of the box body 52 on opposite sides, thereby preventing liquid from leaking from the connection between the second rotating shaft 40 and the box body 52. ​​In addition, in this embodiment, the second rotating shaft 40 is arranged horizontally, so that the driving float 51 can more easily drive the second rotating shaft 40 to rotate when floating up and down.

[0042] Furthermore, a first through hole 521 is provided on the box body 52, and the first through hole 521 penetrates the box body 52, and the level at which the first through hole 521 is located is located below the level at which the driving float 51 is connected to the second rotating shaft 40. When gas or liquid is passed through the second through hole 522, the driving float 51 can swing at least 90 degrees, and increasing the swing angle of the driving float 51 can provide a larger selection space for the sector gear 41 and the curved gear 21.

[0043] Specifically, in this embodiment, the first through hole 521 is provided on the side wall of the housing 52. When the signal float 30 release device is in use, the housing 52 can be filled with air or negative pressure in advance, and the driving float 51 can be in a naturally hanging state, the sector gear 41 is meshed with the curved gear 21, and liquid is gradually injected into the housing 52 through the first through hole 521, so that the driving float 51 gradually swings upward to achieve the effect of separating the sector gear 41 from the curved gear 21. Of course, in some other embodiments, the housing 52 can be filled with liquid in advance, and the driving float 51 can be in a state of floating to the highest position, and then the liquid in the housing 52 can be gradually discharged through the first through hole 521, so that the driving float 51 gradually swings downward to achieve the effect of separating the sector gear 41 from the curved gear 21.

[0044] Preferably, in this embodiment, there are multiple first through holes 521, which are arranged at intervals along the circumference of the box body 52. ​​By providing multiple first through holes 521, the rate of liquid level rise or fall in the box body 52 can be increased, thereby reducing the time for the signal float 30 release device to release the signal float 30. In addition, the multiple first through holes 521 are located at the same height.

[0045] Furthermore, a second through hole 522 is provided on the box body 52, and the second through hole 522 penetrates the box body 52 and is located at the top of the box body 52. ​​When liquid is injected into the box body 52 through the first through hole 521, the second through hole 522 can accelerate the discharge of gas in the box body 52. ​​When the liquid in the box body 52 is discharged through the first through hole 521, the second through hole 522 can provide air into the box body 52, accelerating the discharge of the liquid in the box body 52.

[0046] Furthermore, a one-way air valve 523 is connected to the second through hole 522, and the air outlet direction of the one-way air valve 523 is toward the outside of the box body 52, so that when the signal float 30 release device is placed in the liquid, the liquid will not enter the float from the second through hole 522. At the same time, when the liquid is introduced into the box body 52 through the first through hole 521, the air can be discharged through the one-way air valve 523.

[0047] Since the entire signal float 30 release device only needs to introduce air or liquid into the box 52 during the release process, no motor drive is required. At the same time, there is no need to manually rotate the first shaft 20 or the second shaft. The entire device is a purely mechanical structure and works reliably.

[0048] Furthermore, after the signal float is released, the signal float can be recovered by rotating the first rotating shaft for next use.

[0049] Preferably, in this embodiment, a handle 60 is provided at one end of the first rotating shaft away from the second rotating shaft, and the first rotating shaft can be rotated more conveniently through the handle 60, thereby improving the recovery speed of the signal float.
