Description

Technical Field

[0001] This invention belongs to the field of marine engineering equipment technology, specifically relating to a device for detaching a seabed observation device from its load. Background Technology

[0002] With the rapid development of underwater observation technology, various marine engineering equipment, such as deep-sea detectors, seabed observation platforms, and underwater robots, are widely used. During the operation of these devices, a ballast jettisoning device is often required to actively detach the equipment from its load. Currently, ballast jettisoning devices have become a key component of seabed equipment, and their performance has a significant impact on seabed operations.

[0003] Currently, the mainstream seabed ballast release devices in the industry are mainly divided into two categories. The first category is the explosive bolt type ballast release device: its core structure includes an explosive bolt, a sealed housing, and a load. The explosive bolt connects the sealed housing and the load. During operation, after receiving a control command, the explosive bolt detonates, and the resulting impact force cuts through the weak section of the explosive bolt, thereby separating the load from the main body of the equipment. The second category is the hydraulically triggered ballast release device: it mainly consists of a hydraulic cylinder, a locking pin, and a control valve. The locking pin is used to lock the connection structure between the equipment and the load. During operation, the hydraulic cylinder actuates, pulling out the locking pin, thus detaching the load. However, the above-mentioned existing ballast release devices still have significant technical defects in actual seabed applications and are difficult to meet the needs of use in complex deep-sea environments. For the explosive bolt type ballast release device, the explosive bolt is a disposable product, and the entire bolt needs to be replaced after triggering, making it unusable. For scientific research equipment that requires multiple ballast release tests or batch deployment, the operating cost increases significantly, and the explosion is difficult to control, posing a risk of damaging the main body of the equipment. For hydraulically triggered ballast jettisoning devices, the entire hydraulic drive system is difficult to deploy on small seabed exploration equipment, and the hydraulic system has a complex maintenance process, low versatility, and is difficult to adapt to the rapid reuse requirements of the seabed site. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a device for detaching a seabed observation device from its load.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for detaching a seabed observation equipment from its load includes a seabed load-release device. One end of the seabed load-release device is connected to an electronic pressure-resistant control chamber, and the other end is connected to a coupling frame for mounting the load. The seabed load-release device has a load-release module that is fixedly connected to the electronic pressure-resistant control chamber and detachably connected to the coupling frame. The load-release module is connected to a power module with a built-in drive motor that drives the load-release module to perform a release action after receiving a command. The power module can control the locking state of the load-release module, which facilitates the user in releasing the load, improves the load-release efficiency, and reduces the installation space due to the built-in drive motor, making it suitable for small equipment and improving the equipment's versatility.

[0006] In the aforementioned seabed observation equipment and load release device, the load release module includes a release shell fixedly connected to the electronic pressure-resistant control chamber at its upper end, an outer shell fixedly connected to the lower end of the release shell, a sleeve fixedly provided on the inner circumferential side of the outer shell, a load connecting plate fixedly connected to the sinking frame below the sleeve, and a connecting plate cylinder that can be detached from the inner circumferential side of the sleeve by an elastic top-pressing locking mechanism at the upper center of the load connecting plate. The elastic top-pressing locking mechanism can lock the sleeve and the connecting plate cylinder together, ensuring that the sinking frame can drive the electronic pressure-resistant control chamber to sink, ensuring the observation effect, and the connecting plate cylinder and the load connecting plate are an integral structure, which can ensure the connection strength.

[0007] In the aforementioned seabed observation equipment and load detachment device, the elastic top-pressing locking mechanism includes a mandrel vertically movably disposed on the inner circumference of the connecting plate cylinder and extending upward to the inner circumference of the outer shell. A radial locking component is provided between the mandrel, the connecting plate cylinder, and the sleeve to position the connecting plate cylinder on the inner circumference of the sleeve. An elastic top-pressing component is provided between the mandrel and the load connecting plate, and between the connecting plate cylinder and the outer shell. The mandrel and the radial locking component ensure a locked connection between the connecting plate cylinder and the sleeve, thereby ensuring the equipment sinking effect. The elastic top-pressing component is in a compressed state when locked, and when it is necessary to release the locked state, the mandrel and the outer shell can be pushed upward by the compressive force of the elastic top-pressing component to release the locked state between the sleeve and the connecting plate cylinder.

[0008] In the aforementioned device for detaching a seabed observation equipment from a load, the elastic pressing assembly includes a core rod pressing spring disposed between the lower end of the core rod and the load connecting plate and located inside the connecting plate cylinder. A load plate pressing spring is disposed between the upper end of the connecting plate cylinder and the inner side of the upper end of the outer shell. The core rod pressing spring drives the upper end of the core rod to push upward, causing the lower end of the core rod to disengage from the radial locking assembly. The load plate pressing spring also drives the outer shell to push upward, causing the sleeve to disengage from the radial locking assembly, thereby improving unlocking efficiency and ensuring unlocking effect.

[0009] In the aforementioned device for detaching a seabed observation equipment from its load, the radial locking assembly includes several radially movable holes arranged circumferentially around the connecting plate cylinder. The diameter of the end of the radially movable hole located on the outer side of the connecting plate cylinder is smaller than the diameter of the end located on the inner side of the connecting plate cylinder. A steel ball is movably disposed within each radially movable hole. The outer side of the steel ball protrudes from the outer side of the radially movable hole and abuts against a positioning groove on the inner circumferential side of the upper end of the sleeve. The outer side of the steel ball protrudes from the inner side of the connecting plate cylinder and is connected to the core rod. The outer side abuts against the core rod. The lower end of the core rod has a conical part that allows the steel ball to move towards the core rod when the core rod moves upward, thereby disengaging the steel ball from the positioning groove. The connecting plate cylinder has a load chamber. The steel ball is movably disposed between the radial movable hole and the load chamber. In the locked state, the positioning groove and the conical part can fix the steel ball in the radial movable hole, and the sleeve can be connected to the connecting plate cylinder through the steel ball. In the unlocked and unloaded state, the positioning groove and the conical part are disengaged from the steel ball, and the steel ball rolls into the load chamber, completing the unlocking and unloading operation.

[0010] In the aforementioned seabed observation equipment and load release device, the upper end of the outer shell has a mounting hole. Two cylindrical top blocks with a split structure are horizontally movable inside the mounting hole and can abut against the upper end of the core rod. The mounting hole facilitates radial displacement of the cylindrical top blocks. In the locked state, the two cylindrical top blocks are combined and abut against the upper end of the core rod, and the elastic pressing components are all in a compressed state. In the unlocked and load-released state, the cylindrical top blocks separate from each other, and the upper end of the core rod is pushed out toward the mounting hole through the elastic pressing components, completing the unlocked and load-released operation and ensuring the load-released effect.

[0011] In the aforementioned seabed observation equipment and load release device, the power module includes a load release transmission assembly disposed within the release housing, which enables two cylindrical top blocks to approach each other and abut against the upper end of the mandrel, or to move the two cylindrical top blocks away from each other and detach from the mandrel. The load release transmission assembly is connected to a drive assembly located outside the release housing. The drive assembly can control the load release transmission assembly to drive the cylindrical top blocks, thereby controlling the locking state of the mandrel, improving unlocking efficiency, and ensuring locking and unlocking effects.

[0012] In the aforementioned seabed observation equipment and load release device, the load release transmission assembly includes a forward and reverse threaded rod axially disposed within the release housing. Both ends of the forward and reverse threaded rod are fixed to the housing via a support end bearing mounting seat and a fixed end bearing mounting seat, respectively. Each support end bearing mounting seat and the fixed end bearing mounting seat contains a bearing body sleeved on the forward and reverse threaded rod. Two threaded rod nut seats are provided between the support end bearing mounting seat and the fixed end bearing mounting seat. These threaded rod nut seats are respectively disposed on two parallel trigger blocks, and are fixedly disposed in the middle of the trigger blocks. The two ends of the trigger blocks are guided by the threaded rod. The component is slidably disposed within the release housing. The cylindrical top block is fixedly disposed on one side of the trigger block by fixing bolts. The support end bearing mounting seat and the fixed end bearing mounting seat can support both ends of the positive and negative threaded rods. The bearing body can reduce the rotational friction of the positive and negative threaded rods, ensuring the transmission effect. The positive and negative threaded rods can rotate through the drive component, causing the threaded rod nut seat to move closer or further away from each other. This causes the cylindrical top blocks on the trigger block to move closer to each other to press and lock the mandrel, or to move further away to unlock the mandrel. The threaded rod guide component can ensure the sliding stability and smoothness of the trigger block within the release housing, ensuring locking and unlocking efficiency.

[0013] In the aforementioned seabed observation equipment and load detachment device, the lead screw guide assembly includes lead screw guide rails respectively disposed on both sides of the upper end of the release housing. The lead screw guide rails are arranged parallel to the positive and negative threaded lead screws and are respectively disposed at both ends of the trigger block. Lead screw sliders are fixedly disposed at both ends of the trigger block. The lead screw sliders are slidably disposed on the lead screw guide rails. The lead screw guide rails can guide the trigger block, and the lead screw sliders can make the trigger block slide smoothly and stably on the lead screw guide rails.

[0014] In the aforementioned device for detaching a seabed observation equipment from a load, the drive assembly includes a synchronous pulley sleeved on one end of a positive and negative threaded rod. The motor shaft of the built-in drive motor is connected to a transmission shaft via a coupling. A transmission pulley is sleeved on the transmission shaft. The transmission pulley and the synchronous pulley are connected by a synchronous belt. The coupling ensures the transmission effect between the motor shaft and the transmission shaft. The synchronous pulley, synchronous belt, and transmission pulley enable the built-in drive motor to drive the positive and negative threaded rod to rotate, thereby controlling the cylindrical top block on the trigger block to complete the locking or receiving operation, improving the locking or unlocking efficiency.

[0015] Compared with existing technologies, the advantages of this invention are: 1. After the equipment is unloaded, the electronic pressure-resistant control chamber, release shell, outer shell, and power module can be floated and recovered, reducing the cost of equipment use; 2. The locking or unlocking effect of the mandrel can be guaranteed by the cooperation between the power module and the cylindrical top block; 3. The elastic top-pressure locking mechanism can connect the outer shell to the sinking frame through the load connecting plate in the locked state, ensuring the sinking effect of the electronic pressure-resistant control chamber; and in the unlocked state, it can detach the outer shell from the load connecting plate, ensuring the unlocking and load throwing effect. 4. The built-in drive motor has a simple structure, occupies less space, and is suitable for small equipment, making it more versatile. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, this invention relates to a device for detaching a load from a seabed observation device, comprising a seabed load-release device 1. One end of the seabed load-release device 1 is connected to an electronic pressure-resistant control chamber 11, and the other end is connected to a sinking frame 12 for mounting the load. The seabed load-release device 1 has a load-release module 2 that is fixedly connected to the electronic pressure-resistant control chamber 11 and detachably connected to the sinking frame 12. The sinking frame 12 has a rectangular frame structure, and the load-release module is located in the middle of the sinking frame 12. Each of the four corners of the sinking frame 12 is equipped with a load-bearing block, which can improve the sinking efficiency. The load-release module 2 is connected to a power module 3 with a built-in drive motor 31, which is used to drive the load-release module 2 to perform a release action after receiving a command. The power module 3 can control the locking state of the load-release module 2, which can facilitate the user to release the load, improve the load-release efficiency, and the built-in drive motor 31 can reduce the installation space, making it suitable for small equipment and improving the equipment's versatility.

[0020] Specifically, the load release module 2 includes a release housing 21 whose upper end is fixedly connected to the electronic withstand pressure control chamber 11. A shell 22 is fixedly connected to the lower end of the release housing 21. A sleeve 23 is fixedly provided on the inner circumference of the shell 22, and the sleeve 23 is fixedly connected to the shell 22 on the outer circumference by several fixing bolts. When load release is triggered, the electronic withstand pressure control chamber 11, the release housing 21, the shell 22, and the sleeve 23 can all float up for recovery and reuse, reducing operating costs. Furthermore, a load connection plate 24 is provided below the sleeve 23 and fixedly connected to the coupling frame 12. The load connecting plate 24 is fixedly connected to the sinking frame 12 on the outer periphery by several fixing bolts to ensure connection stability. The upper center of the load connecting plate 24 has a connecting plate cylinder 25 that can be detachably connected to the inner periphery of the sleeve 23 by an elastic top-pressing locking mechanism 4. The elastic top-pressing locking mechanism 4 can lock the sleeve 23 and the connecting plate cylinder 25 together, ensuring that the sinking frame 12 can drive the electronic pressure-resistant control chamber 11 to sink, ensuring the observation effect. The connecting plate cylinder 25 and the load connecting plate 24 are an integral structure, which can ensure the connection strength.

[0021] The elastic top-pressing locking mechanism 4 includes a core rod 41 that is vertically movably disposed on the inner side of the connecting plate cylinder 25 and extends upward to the inner side of the outer shell 22. A radial locking component 42 is provided between the core rod 41, the connecting plate cylinder 25, and the sleeve 23 to position the connecting plate cylinder 25 on the inner side of the sleeve 23. An elastic top-pressing component 43 is provided between the core rod 41 and the load connecting plate 24, and between the connecting plate cylinder 25 and the outer shell 22. The core rod 41 and the radial locking component 42 can ensure that the connecting plate cylinder 25 and the sleeve 23 are locked, thereby ensuring the sinking effect of the equipment. The elastic top-pressing component 43 is in a compressed state when locked, and when it is necessary to release the locked state, the compression force of the elastic top-pressing component 43 can push the core rod 41 and the outer shell 22 upward to release the locked state between the sleeve 23 and the connecting plate cylinder 25.

[0022] like Figure 4 , Figure 6 , Figure 7 As shown, the elastic pressing assembly 43 includes a core rod pressing spring 431 disposed between the lower end of the core rod 41 and the load connecting plate 24 and located inside the connecting plate cylinder 25. A load plate pressing spring 432 is disposed between the upper end of the connecting plate cylinder 25 and the inner side of the upper end of the outer shell 22. The core rod pressing spring 431 drives the upper end of the core rod 41 to push upward, so that the lower end of the core rod 41 is disengaged from the radial locking assembly 42. The load plate pressing spring 432 can drive the outer shell 22 to push upward, so that the sleeve 23 is disengaged from the radial locking assembly 42, thereby improving the unlocking efficiency and ensuring the unlocking effect.

[0023] Furthermore, the radial locking assembly 42 includes a plurality of radially movable holes 421 disposed circumferentially around the connecting plate cylinder 25. The diameter of the end of the radially movable hole 421 located on the outer side of the connecting plate cylinder 25 is smaller than the diameter of the end located on the inner side of the connecting plate cylinder 25. A steel ball 422 is movably disposed within the radially movable hole 421. The outer side of the steel ball 422 protrudes from the end of the radially movable hole 421 located on the outer side of the connecting plate cylinder 25 and abuts against the positioning groove 423 on the circumferential inner side of the upper end of the sleeve 23. The outer side of the steel ball 422 protrudes from the end of the connecting plate cylinder 25 and abuts against the outer side of the mandrel 41. The lower end of the mandrel 41 has a feature that allows the mandrel 41 to move upward. The steel ball 422 can move towards the mandrel 41, thereby disengaging the steel ball 422 from the conical part 424 of the positioning groove 423. The connecting plate cylinder 25 has a load cavity. The steel ball 422 is movably disposed between the radial movable hole 421 and the load cavity. In the locked state, the steel ball 422 can be fixedly disposed in the radial movable hole 421 through the positioning groove 423 and the conical part 424, and the sleeve 23 can be connected to the connecting plate cylinder 25 by the steel ball 422. In the unlocked and unloaded state, the positioning groove 423 and the conical part 424 are both disengaged from the steel ball 422, and the steel ball 422 rolls into the load cavity, completing the unlocking and unloading operation.

[0024] The outer shell 22 has a mounting hole 221 at its upper end. Two cylindrical top blocks 222 with a split structure are horizontally movable in the mounting hole 221 and can abut against the upper end of the core rod 41. The mounting hole 221 allows the cylindrical top blocks 222 to move radially. In the locked state, the two cylindrical top blocks 222 are combined and abut against the upper end of the core rod 41, and the elastic pressing components 43 are all in a compressed state. In the unlocked and unloaded state, the cylindrical top blocks 222 separate from each other, and the upper end of the core rod 41 is pushed out toward the mounting hole 221 through the elastic pressing components 43 to complete the unlocked and unloaded operation and ensure the unloaded effect.

[0025] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the power module 3 includes a release transmission assembly 32 disposed inside the release housing 21, which can bring the two cylindrical top blocks 222 closer together to abut against the upper end of the mandrel 41 or move the two cylindrical top blocks 222 away from each other to disengage from the mandrel 41. The release transmission assembly 32 is connected to a drive assembly 33 located outside the release housing 21. The drive assembly 33 can control the release transmission assembly 32 to drive the cylindrical top blocks 222, thereby controlling the locking state of the mandrel 41, improving unlocking efficiency, and ensuring locking and unlocking effects.

[0026] The load release transmission assembly 32 includes a positive and negative threaded screw 321 axially disposed within the release housing 21. Both ends of the positive and negative threaded screw 321 are fixedly mounted on the housing 22 via a support end bearing mounting seat 322 and a fixed end bearing mounting seat 323, respectively. Both the support end bearing mounting seat 322 and the fixed end bearing mounting seat 323 contain bearing bodies 324 sleeved on the positive and negative threaded screw 321. Two screw nut seats 325 are provided between the support end bearing mounting seat 322 and the fixed end bearing mounting seat 323. The screw nut seats 325 are respectively disposed on two parallel trigger blocks 326, and are fixedly disposed in the middle of the trigger blocks 326. Both ends of the trigger blocks 326 are slidably disposed within the release housing 21 via a screw guide assembly 5. The cylindrical top block 222 is fixedly mounted on one side of the trigger block 326 by fixing bolts. The support end bearing mounting seat 322 and the fixed end bearing mounting seat 323 can support both ends of the positive and negative threaded rod 321. The bearing body 324 can reduce the rotational friction of the positive and negative threaded rod 321 and ensure the transmission effect. The positive and negative threaded rod 321 can drive the threaded rod nut seat 325 to move closer or further apart through the drive assembly 33. This causes the cylindrical top blocks 222 on the trigger block 326 to move closer to each other to press and lock the core rod 41 or move further apart to unlock the core rod 41. The threaded rod guide assembly 5 can ensure the sliding stability and smoothness of the trigger block 326 in the release housing 21 and ensure the locking and unlocking efficiency.

[0027] Specifically, the lead screw guide assembly 5 includes lead screw guide rails 51 respectively disposed on both sides of the upper end of the release housing 21. The lead screw guide rails 51 are arranged parallel to the positive and negative thread lead screws 321 and are respectively disposed at both ends of the trigger block 326. Lead screw sliders 52 are fixedly disposed at both ends of the trigger block 326. The lead screw sliders 52 are slidably disposed on the lead screw guide rails 51. The lead screw guide rails 51 can guide the trigger block 326, and the lead screw sliders 52 can make the trigger block 326 slide smoothly and stably on the lead screw guide rails 51.

[0028] Combination Figure 3 , Figure 4As shown, the drive assembly 33 includes a synchronous pulley 331 sleeved on one end of the positive and negative threaded rod 321. The motor shaft of the built-in drive motor 31 is connected to the transmission shaft 333 through a coupling 332. A transmission wheel 334 is sleeved on the transmission shaft 333. The transmission wheel 334 and the synchronous pulley 331 are connected by a synchronous belt 335. The coupling 332 can ensure the transmission effect between the motor shaft and the transmission shaft 333. The synchronous pulley 331, the synchronous belt 335 and the transmission wheel 334 can enable the built-in drive motor 31 to drive the positive and negative threaded rod 321 to rotate, thereby controlling the cylindrical top block 222 on the trigger block 326 to complete the locking or receiving operation, improving the locking or unlocking efficiency.

[0029] The principle of this embodiment is as follows: In the locked state: the upper end of the core rod 41 abuts against the cylindrical top block 222, and the elastic pressing component 43 is in a compressed state. The sleeve 23 can be locked with the connecting plate cylinder 25 through the radial locking component 42, and the load connecting plate 24 is fixedly connected to the sinking frame 12, which can ensure the sinking effect of the electronic pressure-resistant control chamber 11. In the unlocked and unloaded state: the power module 3 can control the cylindrical top block 222 to separate from each other, so that the upper end of the core rod 41 is pushed out toward the mounting hole 221. The elastic pressing component 43 can make the sleeve 23 and the core rod 41 disengage from the radial locking component 42 to complete the unlocking operation. The elastic pressing locking mechanism 4, the load connecting plate 24 and the sinking frame 12 continue to sink, and the electronic pressure-resistant control chamber 11, the release shell 21, the outer shell 22 and the power module 3 float up and are recovered, reducing the cost of use.
