Description

Technical Field

[0001] The utility model relates to the technical field of marine equipment, and more specifically, to a self-balancing marine preloaded launching platform. Background Art

[0002] Ocean launch platforms must be deployed in the ocean ahead of time, using buoyancy to maintain afloat. During deployment, the launch platform must maintain excellent stability to ensure long-term operation in the ocean. The platform is pre-loaded with one or more functional products and is launched at an opportune moment based on launch instructions or other requirements. A single launch module is typically sealed. Before launch, despite its internal payload, the entire module maintains positive buoyancy, ensuring the stability of the entire launch platform. However, as the module is launched, its upper end cap opens, allowing water to enter the interior, significantly reducing its buoyancy and, consequently, the positive buoyancy of the entire launch system, potentially compromising the stability of the entire launch system and the launch platform. Furthermore, the deployment environment of an ocean launch platform is quite complex. A decrease in buoyancy can make the equipment more susceptible to undesirable conditions such as tilting or inverting, potentially preventing the launch port from facing upward or above the water surface, impacting normal operation. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a self-balancing ocean preload launch platform that can maintain the positive buoyancy of the equipment and stably keep the posture of the entire platform stable.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A self-balancing ocean preload launch platform comprises a launch system carrier, a counterweight compartment and a variable buoyancy module, wherein the launch system carrier is provided with a plurality of launch tubes, the upper ends of the launch tubes are provided with launch end covers, and the launch end covers extend from the upper end of the launch system carrier, and the launch end covers can seal and cover the launch tubes; the counterweight compartment is provided at the lower part of the launch system carrier for counterweight; the variable buoyancy module comprises an inflatable airbag, an annular cavity is provided on the outer wall of the upper end of the launch system carrier, the annular cavity and the inner cavity of the launch system carrier are sealed and separated from each other, and the inflatable airbag has an annular structure and is located in the annular cavity.

[0006] The present invention is further configured such that an opening extending outward is provided on the outer periphery of the annular cavity, and a portion of the inflatable airbag can elastically inflate outward from the opening of the annular cavity.

[0007] The present invention is further configured such that the open outer side of the annular cavity is covered by a coating layer, and the coating layer is a material that dissolves in water.

[0008] The present invention is further configured such that the variable buoyancy module further includes a high-pressure gas generating device and an air guide tube, and the high-pressure gas generating device is connected to the inflatable airbag via the air guide tube.

[0009] The present invention is further configured such that the high-pressure gas generating device comprises a high-pressure gas cylinder and a valve device, wherein the valve device is installed on the high-pressure gas cylinder to control the on and off of the high-pressure gas.

[0010] The present invention is further configured such that an extension tube is fixedly connected to the lower portion of the launch system carrier, the high-pressure gas generating device is disposed in the extension tube, and the gas guide tube is arranged in the launch system carrier.

[0011] The present invention is further configured such that the launch end cover is rotatably connected to the launch tube via a hinge, and a spring is installed at the hinge for elastically driving the launch end cover to open; an electromagnetic lock is provided between the launch end cover and the launch tube, and the electromagnetic lock can magnetically lock the launch end cover in a closed position.

[0012] The utility model is further configured such that the counterweight cabin is slidably connected to the lower side of the launch system carrier through a slide rod; the lower part of the launch system carrier is fixedly connected to a guide slide, the slide rod is slidably connected to the guide slide, and the counterweight cabin can be adjusted up and down along the slide rod.

[0013] The present invention is further configured such that a connecting rope is connected between the launch system carrier and the counterweight cabin.

[0014] The present invention is further configured such that a cutting device is provided at the lower portion of the launch system carrier, and the cutting device can cut off the connecting rope and can cut off and release the counterweight cabin.

[0015] In summary, the present invention has the following beneficial effects:

[0016] By setting up a counterweight cabin, the launch system carrier and the entire platform can be counterweighted, the attitude stability of the entire platform can be maintained, the upper end of the launch system carrier can be stably kept facing upward, and the equipment can work normally.

[0017] By installing a variable buoyancy module, the inflatable airbag in the variable buoyancy module can elastically expand, thereby increasing the positive buoyancy of the entire platform and maintaining the platform's stable afloat. Furthermore, the inflatable airbag is installed at the outer periphery of the upper end of the launch system carrier. This upper installation position can stably ensure that the upper end of the launch system carrier is facing upward. If the inflatable airbag is installed at the lower side of the launch system carrier, while it can also increase the buoyancy of the entire platform and keep the entire platform in a stable floating state, it may cause excessive positive buoyancy on the lower side of the launch system carrier, resulting in an unstable posture of the entire launch system carrier and launch platform, which is prone to movement and even tilting and shifting. By installing the inflatable airbag at the upper side of the launch system carrier, the posture of the device can be more stably maintained, significantly improving this problem. Furthermore, the high-pressure gas generator of the variable buoyancy module is located at the lower side of the launch system carrier, which can make the weight of the entire variable buoyancy module light at the top and heavy at the bottom, further facilitating the maintenance of the entire device's posture.

[0018] By adopting a sliding and adjustable structure in the counterweight cabin and the launch system carrier, the distance between the counterweight cabin and the launch system carrier can be adjusted; the distance between the counterweight cabin and the launch system carrier can be increased, thereby increasing the distance between the upper and lower parts of the entire platform, and the center of gravity of the entire platform will be further lower, further maintaining the stability of the posture of the entire platform.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This embodiment discloses a self-balancing ocean preload launch platform, referring to Figure 1-4 As shown, it includes a launch system carrier 1, a counterweight cabin 6 and a variable buoyancy module 111, wherein the launch system carrier 1 is roughly a cylindrical structure, and a number of launch tubes 2 and a control cabin 4 are arranged in the launch system carrier 1. The control cabin 4 is installed in the middle of the launch system carrier 1, and is equipped with components such as a communication module, a control module and a power supply; a number of launch tubes 2 are distributed on the periphery of the control cabin 4, and the loading equipment can be launched through the launch tubes 2.

[0026] A launch cover 3 is mounted on the upper end of the launch tube 2, which extends from the upper end of the launch system carrier 1. This seals the launch tube 2 and its interior, providing the launch system carrier 1 with positive buoyancy and allowing it to float. A counterweight compartment 6 is located below the launch system carrier 1, providing counterweight and maintaining a stable posture. The upper end of the launch tube 2 and the control compartment 4 remain above the water surface due to buoyancy, facilitating launch and signal transmission and reception.

[0027] The launch cover 3 is pivotally connected to the launch tube 2 via a hinge 301. A torsion spring is mounted on the hinge 301, elastically acting between the launch cover 3 and the launch tube 2. This elastic force forces the launch cover 3 to open. An electromagnetic lock 302 is installed between the launch cover 3 and the launch tube 2, magnetically locking the launch cover 3 in the closed position.

[0028] When the launch tube 2 needs to be launched, the electromagnetic lock 302 is opened, and the spring elastically drives the launch end cover 3 to flip open. After the launch end cover 3 is opened, the load in the launch tube 2 can be launched.

[0029] After the launch tube 2 is launched, the upper end of the launch tube 2 will be in an open state, and water will enter the interior, causing the buoyancy of the launch tube 2 to decrease. As the launch tube 2 is continuously launched, the buoyancy generated by the launch tube 2 decreases, causing the overall buoyancy of the launch system carrier 1 and each launch tube 2 to decrease, and the buoyancy of the entire self-balancing ocean preload launch platform to also decrease, which may lead to insufficient buoyancy.

[0030] Therefore, in this embodiment, the self-balancing ocean preload launch platform further includes a variable buoyancy module 111. The variable buoyancy module 111 can change the buoyancy by expanding, thereby increasing the overall buoyancy to keep it in a floating state.

[0031] The variable buoyancy module 111 includes an inflatable airbag 14, a high-pressure gas generating device 11 and an air guide tube 12. The inflatable airbag 14 is an annular airbag, for example, it can be made of rubber material. After inflation, it can elastically expand to increase buoyancy, thereby maintaining the buoyancy stability of the entire platform.

[0032] The high-pressure gas generator 11 is connected to the inflatable airbag 14 via an air duct 12, which allows high-pressure gas to be introduced into the inflatable airbag 14, causing it to inflate. The high-pressure gas generator 11 includes a high-pressure gas cylinder containing high-pressure gas and a valve assembly mounted on the cylinder. The valve assembly controls the flow of high-pressure gas, allowing gas to be introduced when the inflatable airbag 14 is inflated.

[0033] The inflatable bladder 14 is an annular structure and fits around the outer periphery of the launch system carrier 1. An annular cavity 13 is defined in the upper outer wall of the launch system carrier 1, which is sealed and separated from the inner cavity of the launch system carrier 1. The inflatable bladder 14 is an annular structure that conforms to the shape of the annular cavity 13 and is embedded within it. An outwardly extending opening is defined on the outer periphery of the annular cavity 13, and a portion of the inflatable bladder 14 is capable of elastically expanding outward from the opening.

[0034] On the one hand, the annular cavity 13 can accommodate and limit the inflatable airbag 14, maintaining the structural stability between the inflatable airbag 14 and the launch system carrier 1; on the other hand, the inflatable airbag 14 is embedded in the annular cavity 13 and will not affect the periphery of the launch system carrier 1 when it is not inflated.

[0035] Furthermore, the outer surface of the open annular cavity 13 is covered by a coating 15 made of a water-soluble material. For example, the coating 15 can be made of paper. During transportation, the coating 15 can keep the outer wall of the launch system carrier 1 relatively flat, preventing the contents from falling. When immersed in water, the coating 15 becomes moist and softened, allowing water to penetrate. When the inflatable airbag 14 is inflated, the coating 15 can be easily ruptured.

[0036] Reference Figure 1 、 Figure 2As shown, an extension tube 5 is fixedly connected to the lower portion of the launch system carrier 1. The extension tube 5 has a similar cylindrical structure to the launch system carrier 1. Located at the lower portion of the launch system carrier 1, the extension tube 5 extends downward and houses various equipment. A high-pressure gas generator 11 is mounted within the extension tube 5. An air duct 12 is disposed within the launch system carrier 1. The air duct 12 can be installed within the sidewall of the launch system carrier 1 or within a gap within the launch system carrier 1, connecting the high-pressure gas generator 11 to the inflatable airbag 14.

[0037] The counterweight cabin 6 is installed at the bottom of the launch system carrier 1 to play the role of counterweight for the entire launch platform. The counterweight cabin 6 can be installed at the bottom of the extension tube 5 and connected to the launch system carrier 1 through the extension tube 5.

[0038] Specifically, the counterweight compartment 6 is slidably connected to the underside of the launch system carrier 1 via a slide rod 7. A guide carriage 8 is fixedly connected to the interior of the extension tube 5 at the lower portion of the launch system carrier 1. The lower end of the slide rod 7 is fixedly connected to the counterweight compartment 6, while the upper end is slidably connected to the guide carriage 8. The slide rod 7 can slide up and down along the guide carriage 8, thereby adjusting the distance between the counterweight compartment 6 and the launch system carrier 1.

[0039] In order to limit the position between the counterweight cabin 6 and the launch system carrier 1, a connecting rope 9 is connected between the launch system carrier 1 and the counterweight cabin 6. A cutting device 10 is installed in the extension tube 5 at the lower part of the launch system carrier 1. The cutting device 10 can cut the connecting rope 9. After the connecting rope 9 is cut, the counterweight cabin 6 can be cut off and released. The cutting device 10 specifically includes two shear knives 1001. The two shear knives 1001 can rotate relative to each other and can be driven by a driving device. The two shear knives 1001 have shear blades that cooperate with each other. The connecting rope 9 passes between the two shear blades. When it needs to be cut, the shear knives 1001 interact with each other to cut the connecting rope 9.

[0040] In a normal state, the counterweight cabin 6 and the launch system carrier 1 are close to each other, the slide rod 7 is in a retracted state, and the two are limited by a connecting rope 9.

[0041] When the ballast tank 6 needs to be released, the cutting device 10 can cut the connecting rope 9, and the ballast tank 6 can then slide down along the direction of the slide bar 7. The distance between the ballast tank 6 and the launch system carrier 1 will increase, thereby increasing the distance between the upper and lower parts of the entire platform, and the center of gravity of the entire platform will be further downward, further maintaining the stability of the entire platform. Generally, this attitude adjustment is usually performed when the launch tube 2 is fired multiple times and the platform buoyancy decreases. This attitude adjustment can maintain the platform attitude as stable as possible. Moreover, since the inflatable airbag 14 of the variable buoyancy module 111 is located on the upper side of the launch system carrier 1, that is, at the upper position of the entire platform, the inflatable airbag 14 is positively buoyant and the ballast tank 6 is positively buoyant. The up-down position can further reduce the center of gravity of the entire platform, and the positive buoyancy of the upper part is also more stable, thereby stably maintaining the upper end of the launch system carrier 1 facing forward, and the equipment can launch normally.
