Description

Technical Field

[0001] This invention relates to the field of encapsulation technology, and in particular to an encapsulation tube and an underwater vehicle using the encapsulation tube. Background Technology

[0002] Currently, underwater vehicles are widely used in marine operations, such as underwater gliders and autonomous underwater vehicles, which can perform underwater exploration, deep-sea observation, and various military missions.

[0003] Before being put into use, underwater vehicles are typically installed in a protective enclosure. This enclosure primarily serves to protect the underwater vehicle and prevent damage. During actual deployment, the enclosure must first be opened, and the underwater vehicle is then placed into the water manually or by hoisting.

[0004] However, when entering the water, underwater vehicles lack effective protection, which can easily lead to equipment damage; moreover, deployment operations are greatly affected by sea conditions, have high requirements for sea conditions, and have poor environmental adaptability. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide a sealing cylinder and an underwater vehicle using the sealing cylinder, thereby solving the problems that underwater vehicles lack effective protection when entering the water, which can easily lead to equipment damage; moreover, deployment operations are greatly affected by sea conditions, have high requirements for sea conditions, and have poor environmental adaptability.

[0006] The technical solution of the encapsulation tube of the present invention is as follows:

[0007] The encapsulation tube includes a main tube body and an end cap structure. One end of the main tube body is provided with a sealing part, and the other end of the main tube body is provided with a tube opening. The end cap structure can be detachably installed at the tube opening.

[0008] The end cap structure includes a fixedly connected end plate and a cap edge. The end plate has a water-permeable hole, and the inner side of the end plate is provided with a receiving groove corresponding to the water-permeable hole. A water-soluble block is installed in the receiving groove, and the water-soluble block is used to dissolve or disperse when it comes into contact with water.

[0009] A first through hole is provided on the edge of the cover, and a second through hole is provided on the side wall of the receiving groove. The first through hole and the second through hole are arranged correspondingly, and a spring locking pin is installed between the first through hole and the second through hole.

[0010] The spring locking pin is positioned with its elastic force directed toward the center of the end cap structure. The main cylinder has a pin hole corresponding to the cylinder opening. When the water-soluble block is solid, the spring locking pin is pressed outward into the pin hole to lock the end cap structure. When the water-soluble block disappears, the spring locking pin retracts inward to unlock the end cap structure.

[0011] Furthermore, an elastic element is installed inside the main cylinder. The elastic element is connected to the inner side of the sealing part, and the elastic force direction of the elastic element is set towards the end cap structure, so that when the end cap structure is unlocked, the underwater vehicle in the main cylinder can be elastically pushed out.

[0012] Furthermore, the water-permeable hole is located in the middle of the end plate, and the groove of the receiving groove extends along the central axis of the end plate in the depth direction.

[0013] Furthermore, the receiving groove is cylindrical in shape, and the receiving groove and the cover edge are arranged concentrically, forming an annular space between the receiving groove and the cover edge, and at least two spring locking pins are installed in the annular space.

[0014] Furthermore, the elastic force directions of at least two of the spring locking pins are arranged centrally symmetrically about the central axis of the end plate.

[0015] Furthermore, the spring locking pin includes a locking pin and a return spring. The locking pin is movably inserted into the first through hole and the second through hole, and the return spring is connected between the locking pin and the receiving groove, or the return spring is connected between the locking pin and the cover edge.

[0016] Furthermore, the water-soluble block is a block formed by pressing water-soluble compound powder.

[0017] Furthermore, the water-soluble compound powder is made from any one of calcium chloride, calcium oxide, and magnesium chloride.

[0018] Furthermore, the water-soluble block is a block made of water-soluble polymer material.

[0019] The technical solution of the underwater vehicle of the present invention is as follows:

[0020] The underwater vehicle using the above-mentioned encapsulation tube includes an encapsulation tube and an underwater vehicle body. The underwater vehicle body is installed inside the encapsulation tube, and the ends of the underwater vehicle body are respectively pressed and fitted with the end cap structure and the sealing part.

[0021] The encapsulation cylinder includes a main cylinder body and an end cap structure. One end of the main cylinder body is provided with a sealing part, and the other end of the main cylinder body is provided with a cylinder opening. The end cap structure can be detachably installed at the cylinder opening.

[0022] The end cap structure includes a fixedly connected end plate and a cap edge. The end plate has a water-permeable hole, and the inner side of the end plate is provided with a receiving groove corresponding to the water-permeable hole. A water-soluble block is installed in the receiving groove, and the water-soluble block is used to dissolve or disperse when it comes into contact with water.

[0023] A first through hole is provided on the edge of the cover, and a second through hole is provided on the side wall of the receiving groove. The first through hole and the second through hole are arranged correspondingly, and a spring locking pin is installed between the first through hole and the second through hole.

[0024] The spring locking pin is positioned with its elastic force directed toward the center of the end cap structure. The main cylinder has a pin hole corresponding to the cylinder opening. When the water-soluble block is solid, the spring locking pin is pressed outward into the pin hole to lock the end cap structure. When the water-soluble block disappears, the spring locking pin retracts inward to unlock the end cap structure.

[0025] Furthermore, an elastic element is installed inside the main cylinder. The elastic element is connected to the inner side of the sealing part, and the elastic force direction of the elastic element is set towards the end cap structure, so that when the end cap structure is unlocked, the underwater vehicle in the main cylinder can be elastically pushed out.

[0026] Furthermore, the water-permeable hole is located in the middle of the end plate, and the groove of the receiving groove extends along the central axis of the end plate in the depth direction.

[0027] Furthermore, the receiving groove is cylindrical in shape, and the receiving groove and the cover edge are arranged concentrically, forming an annular space between the receiving groove and the cover edge, and at least two spring locking pins are installed in the annular space.

[0028] Furthermore, the elastic force directions of at least two of the spring locking pins are arranged centrally symmetrically about the central axis of the end plate.

[0029] Furthermore, the spring locking pin includes a locking pin and a return spring. The locking pin is movably inserted into the first through hole and the second through hole, and the return spring is connected between the locking pin and the receiving groove, or the return spring is connected between the locking pin and the cover edge.

[0030] Furthermore, the water-soluble block is a block formed by pressing water-soluble compound powder.

[0031] Furthermore, the water-soluble compound powder is made from any one of calcium chloride, calcium oxide, and magnesium chloride.

[0032] Furthermore, the water-soluble block is a block made of water-soluble polymer material.

[0033] Beneficial effects: This encapsulation cylinder adopts a design consisting of a main cylinder, an end cap structure, a water-soluble block, and a spring locking pin. One end of the main cylinder has a sealing section, and the other end has an opening. The opening can be opened to place the underwater vehicle body inside the encapsulation cylinder, and the end cap structure is installed at the opening to seal it. The encapsulation cylinder effectively protects the underwater vehicle body. The end cap structure includes a fixedly connected end plate and a cap edge. The inner side of the end plate has a receiving groove corresponding to the water-permeable hole. A spring locking pin is installed between the cap edge and the receiving groove. The spring locking pin can move within the first through hole of the cap edge and the second through hole of the receiving groove, allowing the end cap structure to be unlocked or locked.

[0034] Furthermore, a water-soluble block is installed in the receiving groove of the end cap structure. Since the water-soluble block can dissolve or disperse when it comes into contact with water, it is in a solid state before being placed in water. The water-soluble block in the receiving groove exerts an outward pressure on the spring locking pin, causing the spring locking pin to be inserted into the first through hole, the second through hole, and the pin hole of the main cylinder, thereby reliably locking the end cap structure at the cylinder opening.

[0035] After the fabric is placed in water, the water-soluble blocks dissolve or disperse upon contact with the water. When the water-soluble blocks in the containment tank disappear, the spring-loaded locking pin retracts inward towards the center of the end cap structure under elastic force, thus achieving automatic unlocking after the sealing cylinder is submerged. The cylinder opening can only be opened after the sealing cylinder is submerged. Throughout the entire fabric placement process, the underwater vehicle is effectively protected, preventing equipment damage. Furthermore, the integrated deployment of the sealing cylinder and the underwater vehicle is less affected by sea conditions and exhibits strong environmental adaptability.

[0041] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0042] Specific embodiment 1 of the encapsulation tube of the present invention, as follows: Figure 1 , Figure 2 As shown, the encapsulation cylinder includes a main cylinder 1 and an end cap structure 2. One end of the main cylinder 1 is provided with a sealing part 11, and the other end of the main cylinder 1 is provided with a cylinder opening. The end cap structure 2 is detachably installed at the cylinder opening of the main cylinder 1. The end cap structure 2 includes an end plate 21 and a cover edge 22 that are fixedly connected. A water-permeable hole is provided on the end plate 21, and a receiving groove 23 is provided on the inner side of the end plate 21 corresponding to the water-permeable hole. A water-soluble block 24 is installed in the receiving groove 23 of the end cap structure 2. The water-soluble block 24 is used to dissolve or disperse when it comes into contact with water.

[0043] The end cap structure 2 has a first through hole 220 on the cover edge 22 and a second through hole 230 on the side wall of the receiving groove 23. The first through hole 220 and the second through hole 230 are arranged correspondingly, and a spring locking pin 25 is installed between the first through hole 220 and the second through hole 230. The spring force direction of the spring locking pin 25 is set towards the center of the end cap structure 2. The main cylinder 1 has a pin hole 12 corresponding to the cylinder opening. When the water-soluble block 24 is solid, the spring locking pin 25 is pressed outward into the pin hole 12 to lock the end cap structure 2. When the water-soluble block 24 disappears, the spring locking pin 25 retracts inward to unlock the end cap structure 2.

[0044] The encapsulation cylinder adopts a design consisting of a main cylinder 1, an end cap structure 2, a water-soluble block 24, and a spring locking pin 25. One end of the main cylinder 1 is provided with a sealing part 11, and the other end of the main cylinder is provided with a cylinder opening. The cylinder opening can be opened to place the underwater vehicle body 3 inside the encapsulation cylinder, and the end cap structure 2 is installed at the cylinder opening to seal and close the cylinder opening. The encapsulation cylinder provides effective protection for the underwater vehicle body 3. The end cap structure 2 includes a fixedly connected end plate 21 and a cover edge 22. The inner side of the end plate 21 is provided with a receiving groove 23 corresponding to the water-permeable hole. A spring locking pin 25 is installed between the cover edge 22 and the receiving groove 23. The spring locking pin 25 can move in the first through hole 220 of the cover edge 22 and the second through hole 230 of the receiving groove 23. The end cap structure 2 can be unlocked or locked by the spring locking pin 25.

[0045] Furthermore, a water-soluble block 24 is installed in the receiving groove 23 of the end cap structure 2. Since the water-soluble block 24 can dissolve or disperse when it comes into contact with water, before the cloth is put into water, the water-soluble block 24 is in a solid state. The water-soluble block 24 in the receiving groove 23 exerts an outward pressing effect on the spring locking pin 25, so that the spring locking pin 25 is inserted into the first through hole 220, the second through hole 230 and the pin hole 12 of the main cylinder 1, thereby reliably locking the end cap structure 2 at the cylinder opening. After the cloth is put into water, the water-soluble block 24 dissolves or disperses when it comes into contact with water. That is, when the water-soluble block 24 in the receiving groove 23 disappears, the spring locking pin 25 retracts inward toward the center of the end cap structure 2 under the action of elasticity, thereby achieving the purpose of automatic unlocking after the sealed cylinder is put into water. The opening of the sealing cylinder can only be opened after it is submerged in water. During the entire deployment process, the underwater vehicle body 3 is effectively protected, preventing equipment damage. Moreover, the integrated deployment of the sealing cylinder and the underwater vehicle body 3 is less affected by sea conditions and has strong environmental adaptability.

[0046] In this embodiment, an elastic element 10 is also installed inside the main cylinder 1. The elastic element 10 is connected to the inner side of the sealing part 11, and the elastic force direction of the elastic element 10 is set towards the end cap structure 2, so that when the end cap structure 2 is unlocked, the underwater vehicle body 3 is elastically pushed out of the main cylinder 1. Specifically, the elastic element 10 is a cylindrical compression spring. When the end cap structure 2 is locked and the cylinder opening is closed, the end of the cylindrical compression spring is pressed against the underwater vehicle body 3, and the cylindrical compression spring is in a compressed energy storage state. If the end cap structure 2 unlocks by itself, the cylindrical compression spring will release its elastic potential energy, thereby quickly pushing the underwater vehicle body 3 out of the cylinder, completing the automatic cylinder deployment process.

[0047] As a further preferred embodiment, the water-permeable hole is located in the middle of the end plate 21, and the groove depth of the receiving groove 23 extends along the central axis of the end plate 21. Specifically, the receiving groove 23 is cylindrical in shape, and the receiving groove 23 and the cover edge 22 are arranged concentrically, forming an annular space between the receiving groove 23 and the cover edge 22. At least two spring locking pins 25 are installed in the annular space. Furthermore, the elastic force direction of the at least two spring locking pins 25 is centrally symmetrical about the central axis of the end plate 22, and the at least two spring locking pins 25 can reliably lock the end cover structure 2, ensuring stable sealing and closing of the cylinder opening.

[0048] In this embodiment, the spring locking pin 25 includes a locking pin 26 and a return spring 27. The locking pin 26 is movably inserted into the first through hole 220 of the cover edge 22 and the second through hole 230 of the receiving groove 23. The return spring 27 is connected between the locking pin 26 and the cover edge 22. The return spring 27 is a return compression spring. The locking pin 26 is provided with a retaining edge. The return spring 27 is connected between the cover edge 22 and the retaining edge, thereby generating an elastic force on the locking pin 26 pointing towards the center of the receiving groove 23, so as to automatically retract and unlock when the water-soluble block 24 disappears.

[0049] In other embodiments, to meet different usage requirements, a return spring can be connected between the locking pin and the receiving groove. Accordingly, a return tension spring is selected as the return spring, which can also generate an elastic force on the locking pin pointing towards the center of the receiving groove.

[0050] As a further preferred embodiment, the water-soluble block 24 is a block formed by pressing water-soluble compound powder. Specifically, the water-soluble compound powder is made from any one of calcium chloride, calcium oxide, and magnesium chloride. This type of water-soluble compound powder, after pressing, can form a block with a certain structural strength, which can meet the requirements of the top-pressure spring locking pin 25 and keep it in a locked state. Moreover, the water-soluble compound powder can quickly dissolve in water, thereby achieving automatic unlocking within a short time after being submerged.

[0051] In addition, to meet different usage requirements, in other embodiments, the water-soluble block can be a block made of water-soluble polymer materials, such as starch-based water-soluble blocks, cellulose-based water-soluble blocks, animal / plant gum-based water-soluble blocks, polyacrylamide water-soluble blocks, etc. Under normal circumstances, it can be made into a block with a certain strength to press the spring locking pin to keep it in a locked state, and can undergo changes such as dissolution, dispersion, flocculation, and gelation after encountering water.

[0052] In a specific embodiment of the underwater vehicle using the aforementioned encapsulation cylinder of the present invention, the underwater vehicle includes an encapsulation cylinder and an underwater vehicle body 3. The underwater vehicle body 3 is installed inside the encapsulation cylinder, and its ends are respectively pressed and fitted with the end cap structure 2 and the sealing part 11. When the end cap structure 2 is locked and installed at the cylinder opening, it can accurately position the underwater vehicle body 3 inside the cylinder, ensuring that the encapsulation cylinder effectively protects the underwater vehicle body 3. The specific structure of the encapsulation cylinder is the same as that of the various specific embodiments of the encapsulation cylinder in the specific embodiments of the present invention, and will not be described again here.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
