Description

Technical Field

[0001] This utility model belongs to the technical field of ballast jettisoning mechanisms for submersibles, and specifically relates to a constant-depth ballast jettisoning mechanism for submersibles. Background Technology

[0002] Depth-controlled ballast jettisoning is a core method for submersibles to "precisely control buoyancy and depth" during underwater operations. The core tasks of submersibles (such as seabed sampling, biological observation, and equipment maintenance) require hovering or slow movement at a specific depth. If depth-controlled ballast jettisoning is not possible, relying solely on the initial ballast configuration, the submersible may deviate from the target depth due to water current disturbances and changes in its own weight (such as increased weight after sampling), causing the operating equipment to be unable to align with the target, or even missing key observation / operation points.

[0003] Submersibles have a "design limit" to their diving depth (e.g., the pressure hull of a manned submersible has a maximum pressure tolerance). Depth-controlled jettisoning is crucial for proactively preventing excessively deep dives: before the submersible approaches its maximum depth, jettisoning a portion of the ballast reduces its own weight, preventing further depth increases and avoiding damage to the pressure hull due to overpressure. Conversely, blindly jettisoning ballast during ascent can lead to excessively rapid ascent, causing decompression sickness (in manned submersibles) or equipment damage due to sudden pressure changes. Depth-controlled jettisoning, by jettisoning ballast in stages at a predetermined depth, controls the ascent speed, ensuring slow pressure changes and protecting personnel and equipment safety.

[0004] Chinese patent CN217805202U discloses a constant-depth ballast jettisoning mechanism for submersibles and Chinese patent CN105015742A discloses a ballast jettisoning device for deep-sea submersibles. Although both patents achieve convenient jettisoning or loading operations through easy-to-operate jettisoning mechanisms, they are all single-use jettisoning devices and cannot meet the load requirements of submersibles at different diving depths, i.e., the practical requirements of constant-depth jettisoning. Moreover, a jettisoning mechanism can only carry one load, which is not economical and practical.

[0005] To address the problem that existing technologies, where a single jettison mechanism can only carry one load, cannot meet the load requirements of submersibles at different diving depths, and are not economical and practical, it is necessary to improve the structure of the constant-depth jettison mechanism for submersibles, thereby solving the current technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a depth-deep ballast jettisoning mechanism for submersibles. It stores multiple loads in a load chamber and has a power mechanism at the bottom to drive two ballast jettisoning rollers to rotate at the same speed but in opposite directions, thereby controlling the quantity and speed of ballast jettisoning and enabling the submersible to accurately jettison loads at a specific depth.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a depth-deep ballast disposal mechanism for a submersible, comprising a load chamber, a disposal chamber, and an equipment chamber. Multiple loads are stacked within the load chamber, with intervals between them. The disposal chamber is fixedly connected to the bottom of the load chamber. The inner cavities of the load chamber and the disposal chamber are interconnected. The bottom of the disposal chamber has an opening for the loads to enter and exit. A first disposal roller and a second disposal roller are symmetrically arranged within the disposal chamber. The first disposal roller has multiple first support plates along its circumference for placing the loads, and the second disposal roller has multiple second support plates along its circumference for placing the loads. Both ends of the first and second disposal rollers are rotatably connected to the side wall of the disposal chamber. The equipment chamber is fixedly connected to the side wall of the disposal chamber. The equipment chamber contains a power mechanism that drives the first and second disposal rollers to rotate at the same speed but in opposite directions.

[0008] To better realize this utility model, each load has two gate-shaped force-bearing plates symmetrically arranged on its top surface.

[0009] To better realize this utility model, the cross-section of the first support plate and the second support plate is an isosceles triangle structure.

[0010] To better realize this utility model, the ends of the first and second throwing rollers away from the equipment compartment are rotatably connected to the side wall of the throwing compartment via bearings, and the ends of the first and second throwing rollers near the equipment compartment are rotatably connected to the side wall of the throwing compartment via sealed bearings.

[0011] To better realize this utility model, the power mechanism includes a drive motor, a driving gear, a reversing gear, a first bearing bracket, a second bearing bracket, a first transmission gear, a second transmission gear, a first driven gear, a second driven gear, a first transmission chain, and a second transmission chain; The reversing gear meshes with the driving gear, the driving gear is coaxially and fixedly connected to the driving shaft, the first transmission gear is coaxially and fixedly connected to the driving shaft, the two ends of the driving shaft are rotatably connected to the first bearing frame and the ejection chamber respectively through bearings, and the driving shaft passes through the first bearing frame and is connected to the output end of the drive motor; The reversing gear is coaxially fixedly connected to the driven shaft, the second transmission gear is coaxially fixedly connected to the driven shaft, and the two ends of the driven shaft are rotatably connected to the second bearing bracket and the ballast chamber respectively through bearings; The first driven gear and the second driven gear are coaxially fixedly connected to the first loading roller and the second loading roller, respectively. The first transmission gear is driven to the first driven gear through a first transmission chain, and the second transmission gear is driven to the second driven gear through a second transmission chain.

[0012] To better realize this utility model, a locking mechanism is provided inside the equipment compartment. The locking mechanism includes a telescopic cylinder, a locking tooth plate, and a locking gear. The first and second throwing rollers are both coaxially fixedly connected to a locking gear. Each locking gear can be adjusted to mesh with an arc-shaped locking tooth plate. Each locking tooth plate is fixedly connected to a telescopic cylinder. The locking tooth plate is fixedly connected to the telescopic end of the telescopic cylinder, and the fixed end of the telescopic cylinder is fixedly connected to the inner wall of the equipment compartment.

[0013] Beneficial effects: This invention stores multiple loads in a load bin and sets up a dumping bin and an equipment bin at the bottom of the load bin. The first and second dumping rollers are driven by a power mechanism to rotate at the same speed but in opposite directions, controlling the quantity and speed of dumping, so that the submersible can accurately dump loads at a certain depth. The reverse rotation of the two dumping rollers by the power mechanism can also achieve automatic loading, making it more practical and convenient. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example like Figure 1 - Figure 7 As shown, a depth-controlled ballast release mechanism for a submersible includes a load chamber 100, a ballast release chamber 200, and an equipment chamber 300. The load chamber 100, ballast release chamber 200, and equipment chamber 300 are all directly embedded in the bottom of the submersible. Multiple loads 101 are stacked inside the load chamber 100. Each load 101 has two symmetrically arranged portal-shaped force-bearing plates 1015 on its top surface. The portal-shaped force-bearing plates 1015 are not only conducive to hoisting and transporting the loads 101, but also separate the two loads 101 to form a gap, which facilitates the insertion of subsequent support plates to achieve the function of quantitative ballast release and achieve the purpose of depth control.

[0018] The throwing chamber 200 is fixedly connected to the bottom of the load chamber 100. The inner cavities of the load chamber 100 and the throwing chamber 200 are interconnected. The bottom of the throwing chamber 200 is provided with an opening 201 for the load 101 to enter and exit. A first throwing roller 202 and a second throwing roller 203 are symmetrically arranged inside the throwing chamber 200. The first throwing roller 202 is provided with multiple first support plates 204 for placing the load 101 along its circumference. The second throwing roller 203 is provided with multiple second support plates 205 for placing the load 101 along its circumference. The first support plates 204 and the second support plates 205... The cross-section is an isosceles triangle structure. The isosceles triangle structure can effectively improve the strength and load-bearing capacity of the first support plate 204 and the second support plate 205. At the same time, it helps to distribute the force of the load 101 to the first throwing roller 202 and the second throwing roller 203. Part of it is directly transmitted to the side wall of the throwing chamber 200 through the first throwing roller 202 and the second throwing roller 203, and part of it forms a force that causes the first throwing roller 202 and the second throwing roller 203 to rotate. This helps to reduce the locking force on the drive structure and improve the service life of the drive structure.

[0019] The equipment compartment 300 is fixedly connected to the side wall of the throwing tank 200. The ends of the first throwing roller 202 and the second throwing roller 203 away from the equipment compartment 300 are rotatably connected to the side wall of the throwing tank 200 via bearings, and the ends of the first throwing roller 202 and the second throwing roller 203 near the equipment compartment 300 are rotatably connected to the side wall of the throwing tank 200 via sealed bearings. Since the equipment compartment 300 contains a drive structure, it is necessary to keep the environment inside the equipment compartment 300 dry. Therefore, sealed bearings are installed at the positions where the first throwing roller 202 and the second throwing roller 203 pass through the side wall of the throwing tank 200 and connect to the drive structure inside the equipment compartment 300, to prevent water from entering the equipment compartment 300. The installation of the sealed bearings can refer to the sealing bearings of the stern shaft of a ship. Since the sealing bearings of the stern shaft of a ship are a relatively mature existing technology, they will not be described in detail here.

[0020] The equipment compartment 300 is equipped with a power mechanism 301 that drives the first loading roller 202 and the second loading roller 203 to rotate at the same speed but in opposite directions. The power mechanism 301 includes a drive motor 3011, a drive gear 3012, a reversing gear 3013, a first bearing bracket 3014, a second bearing bracket 3015, a first transmission gear 3016, a second transmission gear 3017, a first driven gear 3018, a second driven gear 3019, a first transmission chain 3020, and a second transmission chain 3021. The reversing gear 3013 meshes with the drive gear 3012. The drive gear 3012 is coaxially and fixedly connected to a drive shaft 3022. The first transmission gear 3016 is coaxially and fixedly connected to the drive shaft 3022. The two ends of the drive shaft 3022 are rotatably connected to the first bearing bracket 3014 and the loading compartment 200 respectively via bearings. The drive shaft 3022 passes through… After exiting the first bearing bracket 3014, it is connected to the output end of the drive motor 3011; the reversing gear 3013 is coaxially fixedly connected to the driven shaft 3023, and the second transmission gear 3017 is coaxially fixedly connected to the driven shaft 3023. The two ends of the driven shaft 3023 are rotatably connected to the second bearing bracket 3015 and the loading chamber 200 respectively through bearings; the first driven gear 3018 and the second driven gear 3019 are coaxially fixedly connected to the first loading roller 202 and the second loading roller 203 respectively; the first transmission gear 3016 is driven and connected to the first driven gear 3018 through the first transmission chain 3020, and the second transmission gear 3017 is driven and connected to the second driven gear 3019 through the second transmission chain 3021.

[0021] Since the load 101 of the submersible is an emergency item and is not necessarily discarded, its prolonged placement on the support plate will inevitably subject the power mechanism 301 to long-term stress, affecting its service life. Therefore, this application also includes a locking mechanism 303 in the equipment compartment 300. In the idle state, both the first and second load-discharging rollers 202 and 203 are locked, and the pressure of the load 101 is transmitted to the equipment box and submersible through the locking mechanism 303, thereby preventing components such as the drive motor 3011, the first transmission chain 3020, and the second transmission chain 3021 in the power mechanism 301 from being under long-term stress. The locking mechanism 303 includes a telescopic cylinder 3031, a locking toothed plate 3032, and a locking gear 3033. The first loading roller 202 and the second loading roller 203 are both coaxially fixedly connected to a locking gear 3033. Each locking gear 3033 can be adjusted to mesh with an arc-shaped locking toothed plate 3032. Each locking toothed plate 3032 is fixedly connected to a telescopic cylinder 3031. The locking toothed plate 3032 is fixedly connected to the telescopic end of the telescopic cylinder 3031, and the fixed end of the telescopic cylinder 3031 is fixedly connected to the inner wall of the equipment compartment 300.

[0022] Working principle: like Figure 5As shown, this embodiment has four loads 101, which are defined from top to bottom as load one 1011, load two 1012, load three 1013 and load four 1014 respectively. The first load-throwing roller 202 is provided with four first support plates 204, which are defined as first support plate one 2041, first support plate two 2042, first support plate three 2043 and first support plate four 2044 respectively. The second load-throwing roller 203 is provided with four second support plates 205, which are defined as second support plate one 2051, second support plate two 2052, second support plate three 2053 and second support plate four 2054 respectively. The drive motor 3011 drives the drive shaft 3022 to rotate counterclockwise. The drive gear 3012 and the first transmission wheel rotate counterclockwise together with the drive shaft 3022. The first driven wheel also rotates counterclockwise under the transmission of the first transmission chain 3020 and the first transmission wheel. The first driven wheel drives the first load-throwing roller 202 to rotate counterclockwise. The reversing gear 3013 rotates clockwise under the meshing transmission of the drive gear 3012. Then, under the transmission action of the driven shaft 3023, the second transmission gear 3017, and the second driven wheel, it drives the second load-throwing roller 203 to rotate clockwise. At this time, the load 1011 gradually descends to the critical disengagement state under the support of the second support plate 2051 and the first support plate 2041, while the tips of the second support plate 2052 and the first support plate 2042 rotate into the gap between the load 1011 and the load 1012.

[0023] like Figure 6 As shown, the first load-throwing roller 202 and the second load-throwing roller 203 continue to rotate, and the load 1011 loses the support of the second support plate 2051 and the first support plate 2041 and is thrown out, while the load 2 1012 repeats the action of the load 1011 under the support of the second support plate 2052 and the first support plate 2042.

[0024] The operator can adjust the diving depth of the submersible by controlling the amount of load 101 jettisoned. In an emergency, the speed of the drive motor 3011 can be increased to achieve rapid load jettison and enable the submersible to surface in an emergency.

[0025] like Figure 7As shown, the submersible is performing loading operations. Using lifting and hoisting equipment, the load 101 is placed at the bottom of the opening 201, and then the load 101 is lifted upwards. Simultaneously, the drive motor 3011 is started, causing the drive shaft 3022 to rotate clockwise. The drive gear 3012 and the first transmission wheel rotate clockwise together with the drive shaft 3022. The first driven wheel also rotates clockwise under the transmission of the first transmission chain 3020 and the first transmission wheel. The first driven wheel drives the first loading roller 202 to rotate clockwise. The reversing gear 3013 rotates counterclockwise under the meshing transmission of the drive gear 3012. Then, under the transmission of the driven shaft 3023, the second transmission gear 3017, and the second driven wheel, it drives the second loading roller 203 to rotate counterclockwise, thus beginning loading. Once the load 101 moves upward until the first support plate 204 and the second support plate 205 abut against the bottom surface of the load 101 to form support, the lifting equipment moves downward to continue lifting the next load 101, and so on, until the loading quantity meets the specified requirements.

[0026] After the submersible is loaded or partially jettisoned, the extension of the telescopic cylinder 3031 pushes the arc-shaped locking tooth plate 3032 to engage with the locking gear 3033. At this time, the rotational torque of the load 101 on the first jettison roller 202 and the second jettison roller 203 will be transmitted to the telescopic cylinder 3031 through the action of the locking gear 3033, and then to the equipment compartment 300 and the submersible, while the power mechanism 301 is in a non-stressed state.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
