Background

The release device is widely applied to various ocean detection equipment such as a submerged buoy, a submersible vehicle, a lander and the like, and has the main function of releasing abandoned loads or related equipment. The release modes of the existing underwater release device can be roughly divided into four types: explosive, fuse, magnetic, and mechanical. The explosive releaser has certain potential safety hazard and has adverse effect on precise instruments during underwater explosion. The fusing type releaser fuses based on seawater electrochemical corrosion, and parts are replaced after each fusing release, so that the operation complexity is increased, and the reliability is reduced. The electromagnetic releaser needs to apply large current during working, and has high design requirement.

The mechanical acoustic release device is most widely used, and the working mode of the mechanical acoustic release device is that the release device receives an acoustic instruction, controls a motor to rotate, and drives a specific mechanical structure to realize padlock and release of a load.

With the increase of the use depth, on one hand, the pressure-resistant shell thickness is increased due to the pressure-resistant and watertight requirements of the releaser, the weight of equipment is increased, and the miniaturization is not facilitated; on the other hand, the friction force between the release mechanisms may be increased due to the action of water pressure, which causes the release action of the mechanical mechanism not to be completed normally or the power required by the rotation of the motor to be increased greatly.

Detailed Description

In order to make the embodiments, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1, there is shown an embodiment of a deep sea oil filled mechanical release device and method of use thereof of the present invention. The device comprises a pressure balance plug 1, a watertight plug 2, an oil filling hole plug 3, an upper end cover 4, a shell 5, a lower end cover 6, a release lever clamping groove 7, a release lever 8, a circlip 9, a screw plug 10, a piston 11, a motor 12, a speed reducer 13, a motor fixing seat 14, a thrust bearing 15 and a motor rotating shaft 16.

Further, the watertight plug 2 is mounted on the threaded hole of the upper end cover 4 with a sealing member therebetween.

Furthermore, the upper end of the motor 12 is connected with the watertight plug 2 through a wire, and the lower end is coaxially matched with the speed reducer 13, the rotating shaft 16 and the release lever 8 in sequence.

Further, the speed reducer 13 is mounted on a motor fixing seat 14 by screws, and the motor fixing seat is mounted on the lower end cover 6 by screws.

Furthermore, a platform is arranged on the motor rotating shaft 16, and a thrust bearing 15 is respectively arranged on the upper part and the lower part of the platform, the lower end cover 6 and the motor fixing seat 14.

Further, the motor rotating shaft 16 passes through a middle hole of the lower end cover 6, and a sealing member is arranged between the motor rotating shaft and the lower end cover.

Further, the lower end cap 6 is assembled integrally with the upper end cap 4 by screws passing through mounting holes in the upper and lower peripheries of the case 5, and the upper end cap 4, the lower end cap 6 and the case 5 are provided with sealing members.

Further, a pressure balance piston 11 is arranged in the pressure balance plug 1, a screw plug 10 is arranged at the upper end of the pressure balance plug 1, and an elastic retainer ring 9 is arranged in a clamping groove at the upper end of the pressure balance plug.

Further, the whole releasing device is immersed in oil, placed in a vacuum box for vacuumizing, and filled with oil without bubbles.

Furthermore, an oil filling hole plug 3 is arranged in the upper end cover 4, and a sealing element is arranged between the oil filling hole plug and the upper end cover 4.

Further, the releasing device vertically passes through a mounting hole reserved on the peripheral outer edge of the lower end cover 4 and is mounted on a transponder or other deep sea platforms through bolts or nuts.

Further, the watertight plug 2 of the release device is connected with a watertight interconnection cable to an acoustic control and power supply module on an external transponder or other deep sea platform.

Furthermore, a release lever clamping groove 7 is welded on the lower end cover 6, the control motor is reversed, a screw rod at the tail end of the motor rotating shaft 16 is arranged in a threaded hole in the release lever 8, and the square head of the release lever 8 is hung in the release lever clamping groove 7.

Further, a load is hung on the end of the release lever 8.

In the pressure balancing process of the deep sea oil-filled mechanical release device in the embodiment shown in fig. 1-4, along with the change of the external water pressure, the pressure balancing piston in the pressure balancing plug 1 slides up and down, so that the internal oil pressure of the release device is consistent with the external water pressure; therefore, the situation that under the action of external water pressure, rolling friction force between the thrust bearing 15 and the motor fixing seat 14 or the lower end cover is increased or the thrust bearing 15 slightly deforms is avoided, the phenomenon that the motor cannot normally rotate or is locked is avoided, and meanwhile, the required input power for the rotation of the motor is reduced.

In the embodiment shown in fig. 1-4, a method for using the deep sea oil-filled mechanical release device is that an external power module is controlled acoustically to supply power to a motor 12 through a watertight plug 2, so as to drive a motor rotating shaft 16 to rotate. The release lever 8 connected to the motor shaft 16 through a screw hole generates relative rotation. Because the square head of the release lever 8 is clamped by the square release lever clamping groove 7 welded on the lower end cover, when the motor 12 rotates reversely, the release lever 8 is gradually loaded upwards into the release lever clamping groove 7; when the motor 12 rotates forwards, the release lever 8 is pushed downwards until the release lever is disengaged, and the load hung on the release lever is disengaged together.

The embodiment shown in the figures 1-4 can effectively balance external water pressure, and the phenomenon that a rotating shaft is blocked due to overlarge friction resistance when the motor rotates is avoided, so that the motor can normally rotate under low power is guaranteed. The releasing mechanism is simple and reliable, and the whole releasing device is small and easy to use.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that variations and modifications within the spirit of the invention may occur to those skilled in the art without departing from the spirit of the invention.
