Description

Technical Field

[0001] The invention relates to the technical field of submersible speed control devices, in particular to an unpowered submersible speed control device for a submersible. Background Art

[0002] The ocean is a valuable asset and expandable space for the sustainable development of human society. It contains rich biological and mineral resources. As an important tool for ocean development, submersibles have developed rapidly and are playing an increasingly important role in the sustainable use of marine resources. Submersibles, especially deep manned submersibles, have a deep operating depth. In order to ensure sufficient underwater operating time, they need to dive and surface at a faster speed within the rated time.

[0003] In terms of diving and surfacing methods, due to the weight, size and energy restrictions of the submersible, its diving and surfacing mostly adopts an unpowered diving and surfacing method based on disposable ballast. This method is affected by environmental factors such as seawater density (seawater density increases with increasing depth), which makes the diving and surfacing speed have the characteristics of a large initial speed and gradually decreasing during the diving and surfacing process. As a result, the submersible needs to increase the ballast weight in order to make the average diving and surfacing speed of the submersible reach the expected value, which is disadvantageous for submersibles with extremely strict weight requirements. At the same time, the passengers are in a variable speed movement, which is not conducive to the comfort of the passengers. Therefore, it is extremely important to reduce the diving and surfacing ballast weight as much as possible while ensuring the diving and surfacing speed of the submersible and improving the comfort of the passengers. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a non-powered diving and surfacing speed control device for a submersible, which can adaptively control the submersible to dive and float at a uniform speed to meet the use requirements.

[0013] The submersible pressure load block is in the shape of a cylinder, and a submersible pressure load block guide hole is axially arranged in the middle of the submersible pressure load block. The submersible pressure load block is mounted on the buoyancy adaptive cabin through the submersible pressure load block guide hole, thereby constituting axial guidance and radial limitation of the submersible pressure load block. Submersible pressure load block grooves are arranged on both sides of the outer surface of the submersible pressure load block, and are symmetrically arranged with respect to the mid-longitudinal section.

[0016] The buoyant ballast releaser and the submerged ballast releaser are connected to the control cabin via cables, and automatic control of the submerged ballast releaser and the buoyant ballast releaser is achieved according to control signals.

[0050] The submerged ballast includes a lower submerged ballast block 8 and an upper ballast block 10 .

[0051] The submersible pressure load block 8 is a cylinder with a submersible pressure load block guide hole 801 axially arranged in the middle. The submersible pressure load block 8 is mounted on the cabin body 3 of the buoyancy adaptive cabin through the submersible pressure load block guide hole 801, thereby constituting axial guidance and radial limitation of the submersible pressure load block 8. Submersible pressure load block grooves 802 are arranged on both sides of the outer surface of the submersible pressure load block 8, and are arranged symmetrically with respect to the mid-longitudinal section.

The submerged ballast adopts a serial configuration, and the diameter, guide hole and groove of the submerged ballast in the series adopt uniform specifications, and the height adopts serial specifications. Submerged ballasts of different heights match different submerged ballast speeds, and submerged ballasts of different specifications can be selected according to the needs of the submerged ballast speed.

[0053] The ballast releaser includes a submersible ballast releaser 9 and a floating ballast releaser 7 .

[0054] There are two submerged ballast releasers 9, which are fixedly connected to the releaser mounting base 202 in the frame assembly 2, and are symmetrically arranged with respect to the longitudinal section of the submerged ballast load block 8, forming longitudinal and circumferential limit fits with the submerged ballast load block grooves 802 on both sides of the submerged ballast load block 8 respectively.

[0057] In actual working process:

[0058] (I) Diving conditions:

[0059] After completing all preparations, the submersible begins to dive. Under the action of the diving pressure load block 8, the submersible enters a negative buoyancy state, and gravity, buoyancy and hydrodynamic force reach a balance in a very short time (this time is small compared to the diving time and can be ignored), and the submersible dives at a predetermined speed. As the depth increases, the density of seawater increases, and at the same time, the external environmental pressure acts on the sliding plate 5. The sliding plate 5 moves toward the top of the cabin 3 under the action of the external environmental pressure and the spring 4, and the displacement volume of the submersible decreases, ensuring that the buoyancy of the submersible remains unchanged, that is, the resultant force of the submersible during the diving process remains unchanged, and then the diving speed of the submersible remains unchanged, and the submersible dives at a uniform speed. When the submersible approaches the target depth, the control cabin 1 automatically controls the submersible ballast releaser 7 to work according to the received control signal, and the submersible ballast releaser motor drives the submersible ballast releaser push rod to retract until the submersible ballast releaser arc clamp is separated from the submersible load block groove 802 on the side of the submersible load block 8, and the submersible load block 8 is separated under its own gravity and the guidance of the cabin 3, and the release is completed. At this time, the gravity and buoyancy of the submersible are balanced, and it enters a balanced state and stops at the target depth, entering the underwater operation stage.

[0060] (II) Floating conditions:

[0061] After the submersible completes the underwater operation, it begins to float. The control cabin 1 automatically controls the floating ballast releaser 7 to work according to the received control signal, and the floating ballast releaser motor 701 drives the floating ballast releaser push rod 702 to contract until the floating ballast releaser arc clamp 703 is separated from the floating ballast load block groove on the side of the floating ballast load block 10, and the floating ballast load block 10 is separated under its own gravity and the guidance of the cabin 3, and the release is completed. After releasing the buoyancy load block 10, the submersible enters a positive buoyancy state. In a very short time (this time is small compared to the buoyancy time and can be ignored), gravity, buoyancy and hydrodynamics reach a balance, and the submersible floats at a predetermined speed. As the depth decreases, the density of seawater decreases. At the same time, the external environmental pressure acts on the sliding plate 5. The sliding plate 5 moves to the bottom of the cabin 3 under the action of the external environmental pressure and the spring 4. The displacement volume of the submersible increases synchronously to ensure that the buoyancy of the submersible remains unchanged, that is, the resultant force on the submersible remains unchanged during the buoyancy process, and thus the buoyancy speed of the submersible remains unchanged. The submersible floats to the surface at a uniform speed and enters the recovery stage.
