Description

Technical Field

[0001] The utility model relates to the technical field of submarine safety equipment, in particular to a manual jettisoning device for a submersible. Background Art

[0002] When submarines are operating underwater, they usually need to carry a certain amount of ballast to maintain a stable diving depth and posture. In the event of an emergency, such as a collision or malfunction, the submarine needs to surface quickly to avoid sinking or further danger. Existing release mechanisms have the following problems:

[0003] 1. Release mechanism reliability issues: The release mechanism is the core component of the ballast jettisoning device, and its reliability is directly related to the device's ability to quickly and accurately jettison the ballast in an emergency. However, existing release mechanisms suffer from high failure rates, slow response speeds, and incomplete unlocking, resulting in ineffective operation at critical moments.

[0004] 2. Ballast vessel sealing: Ballast vessels are required to withstand the high pressure and corrosive environment of the deep sea for extended periods, making their sealing crucial. However, existing ballast vessels suffer from poor sealing, material aging, or corrosion, leading to leakage before the ballast is discarded, compromising the submarine's buoyancy and stability.

[0005] Therefore, it is particularly important to develop a device that can quickly discard ballast to accelerate ascent. Utility Model Content

[0006] The purpose of the utility model is to provide a manual jettisoning device for a submersible, so as to solve at least one of the above-mentioned problems existing in the prior art.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A manual jettisoning device for a submersible comprises an unloading shaft, a ballast container, an outer flange tube and an inner flange tube, the outer flange tube and the inner flange tube being coaxially arranged, the lower end of the flange end of the inner flange tube being fixedly connected to a lower flange cover, the upper end of the inner flange tube being provided with a top cover plate, the unloading shaft and the inner flange tube being rotatably connected, a first bearing being provided between the unloading shaft and the upper end of the inner flange tube, a second bearing being provided between the unloading shaft, the lower end of the inner flange tube and the lower flange cover, a rotating disk being provided at the end of the unloading shaft extending out of the top cover plate, a radially extending buckle being provided at the end of the unloading shaft extending out of the lower flange cover, the buckling edge of the ballast container being located above the buckle, the buckle limiting the position of the ballast container, and the ballast container being loaded with ballast weights.

[0009] In this technical solution, the outer flange tube and the inner flange tube can well protect the unloading shaft. The top cover plate is used to close the top of the inner flange tube. The inner flange tube corresponds to the outer flange tube and together constitutes a support structure to ensure the sealing and stability of the entire device. The inner flange tube works in conjunction with the bearing to ensure the stability and reliability of the unloading shaft. The ballast weight is unlocked by rotating the unloading shaft. The design of the unloading shaft ensures that the action can be performed quickly and accurately in an emergency. The buckle is a quick connection and release mechanism used to clamp the buckle edge of the ballast container so that the lead or iron block in the ballast container remains stable. During emergency surfacing, the rotating disk is manually operated to drive the unloading shaft to rotate, and the buckle at the lower end of the unloading shaft rotates accordingly, thereby realizing the disengagement of the buckle from the buckle edge of the ballast container, thereby realizing the rapid unloading of the ballast weight to release the ballast weight. The device can discard the ballast weight on the submarine in a short time, so that the submarine obtains sufficient buoyancy to quickly surface, thereby ensuring the safety of personnel and equipment.

[0010] Furthermore, the first bearing is a deep groove ball bearing, and the second bearing is a tapered bearing. The deep groove ball bearing supports the unloading shaft, reducing friction and wear during rotation, thereby improving the reliability and service life of the device. The tapered bearing supports the other end of the unloading shaft and provides the necessary radial and axial support.

[0011] Furthermore, in order to better fix the rotating disk, the rotating disk is fixedly mounted on the unloading shaft by means of hexagon socket bolts.

[0012] Furthermore, in order to better fix the top cover plate, a plurality of hexagon socket bolts are circumferentially provided between the top cover plate and the upper end of the inner flange tube.

[0013] Furthermore, in order to improve the sealing effect between the unloading shaft and the inner flange tube and prevent seawater or other media from penetrating into the interior of the device, a plurality of first sealing rings are provided between the unloading shaft and the inner flange tube.

[0014] Furthermore, in order to improve the sealing effect between the lower flange cover and the unloading shaft and prevent seawater or other media from penetrating into the interior of the device, a plurality of second sealing rings are provided between the lower flange cover and the unloading shaft.

[0015] Furthermore, in order to improve the sealing effect of the flange part and prevent seawater or other media from penetrating into the interior of the device, a third sealing ring is provided between the flange end of the outer flange tube and the flange end of the inner flange tube, and a fourth sealing ring is provided between the flange end of the inner flange tube and the lower flange cover.

[0016] Furthermore, in order to improve the stability of the buckle installation, the lower end of the unloading shaft is threadedly connected with a nut, and a cotter pin is provided between the nut and the unloading shaft, and the nut is located below the buckle.

[0017] Furthermore, in order to better achieve stable installation of the lower flange cover, a plurality of hexagon socket bolts are circumferentially provided between the lower flange cover and the flange end of the inner flange tube.

[0018] Furthermore, the ballast container, outer flange pipe and inner flange pipe are made of corrosion-resistant stainless steel 316 material, which can resist erosion and corrosion of seawater and extend the service life of the device.

[0019] The beneficial effects of the present invention are as follows: in this technical solution, the outer flange tube and the inner flange tube can well protect the unloading shaft, the top cover plate is used to close the top of the inner flange tube, the inner flange tube corresponds to the outer flange tube, and together constitute a support structure to ensure the sealing and stability of the entire device, the inner flange tube works in conjunction with the bearing to ensure the stability and reliability of the unloading shaft, the ballast weight is unlocked by rotating the unloading shaft, and the design of the unloading shaft ensures that it can be quickly and accurately executed in an emergency, the buckle is a quick connection and release mechanism used to clamp the buckle edge of the ballast container so that the lead or iron block in the ballast container remains stable, during emergency surfacing, the rotating disk is manually operated to drive the unloading shaft to rotate, and the buckle at the lower end of the unloading shaft rotates accordingly, thereby realizing the disengagement of the buckle from the buckle edge of the ballast container, thereby realizing the rapid unloading of the ballast weight to release the ballast weight, and the device can discard the ballast weight on the submarine in a short time, so that the submarine obtains sufficient buoyancy to quickly surface, thereby ensuring the safety of personnel and equipment.
