Description

Technical Field

[0001] The present invention relates to the technical field of diving equipment, in particular to a ballast system for underwater vehicles. Background Art

[0002] Underwater vehicles, such as unmanned underwater vehicles (UUVs) and submersibles, require high maneuverability and flexible depth control capabilities for ocean exploration, underwater operations, and scientific research. Ballast systems are key components for achieving precise depth control in underwater vehicles, controlling their descent and ascent by adjusting the vehicle's weight.

[0003] Traditional ballast systems are often simple in design and single in function, and may not be able to meet the complex and changeable underwater environment and mission requirements. In actual work, it is usually necessary to navigate in different positions in shallow or deep waters, and common devices are difficult to adapt to different water levels and have poor adaptability. At the same time, it is difficult to float quickly in deep waters and has the defect of slow floating efficiency. Summary of the Invention

[0004] The present invention aims to solve the shortcomings of the background technology and provide an underwater vehicle ballast system, which has the defects of being difficult to adapt to different water levels to adaptively control buoyancy and being difficult to efficiently float when working in deep water and needing to quickly escape.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a ballast system for an underwater vehicle, comprising: a main body, a loading chamber is provided inside the main body, and a plurality of detachable ballast blocks are provided inside the loading chamber; a ballast assembly is provided inside the loading chamber and the ballast blocks, and is used to cooperate with the ballast blocks to perform pressurized diving and drainage buoyancy; a loading assembly is provided inside the loading chamber and is used to fix and install a plurality of ballast blocks; and a detection assembly is provided on the surface of the main body, and is used to detect and judge the status of the main body and the entire vehicle, a battery is provided inside the main body, and a circuit board is provided at the bottom of the battery.

[0006] Furthermore, the ballast assembly includes: a ballast chamber opened inside the ballast block, a liquid inlet pipe opened on the top of the ballast block, and a liquid outlet pipe opened on the bottom of the ballast block, the positions of the liquid outlet pipe and the liquid inlet pipe correspond to each other, and the liquid inlet pipe and the liquid outlet pipe are both connected to the inside of the ballast chamber; two middle partitions arranged inside the ballast chamber, there is a space between the two middle partitions, and the two middle partitions are located between the multiple liquid outlet pipes; a pump pipe opened at the top of the loading chamber, a two-way pump is provided inside the pump pipe, and the liquid inlet pipe and the pump pipe are plugged in.

[0007] Furthermore, the loading assembly includes: a driving groove opened on the inner walls on both sides of the loading chamber, a driving motor is provided on the top inner wall of the driving groove, and a driving rod is connected to the bottom of the driving motor through a driving shaft; a driving block is provided on both sides of the ballast block, and the driving rod is threadedly engaged with the driving block.

[0008] Furthermore, the detection component includes: a plurality of pressure detection tubes opened on the surface of the main body, and the plurality of pressure detection tubes located on the same side are distributed in a fan-shaped structure; a plurality of arc-shaped flow rate detection tubes opened on the surface of the main body, and the flow rate detection tubes are set through the surface of the main body; and a plurality of pressure sensors respectively arranged inside the pressure detection tubes and on the inner walls on both sides of the flow rate detection tubes.

[0009] Furthermore, a plurality of guide rods are provided on the top of the liquid outlet pipe, a closing plate is slidably connected between the plurality of guide rods, and a plurality of flow openings are provided on both sides of the liquid inlet pipe.

[0010] Furthermore, a closing spring is provided between the top of the closing plate and the guide rod, and the closing spring is sleeved on the outer surface of the guide rod.

[0011] Furthermore, limiting grooves are provided on the inner walls of the top and bottom of the ballast chamber, limiting blocks are provided on the top and bottom of the middle partition, and the limiting blocks are slidably connected to the limiting grooves.

[0012] Furthermore, a fixing groove is provided on the inner wall of the driving block, a plurality of receiving openings are provided on the surface of the driving rod, a fixing block is slidably connected inside the receiving opening, a fixing spring is provided between the fixing block and the receiving opening, and the surface of the fixing block is arranged in an arc-shaped structure.

[0013] Furthermore, the detection component process is as follows:

[0014] S1. Water from the surrounding environment is poured into the pressure detection tube. As the device dives deeper, the pressure detected by the pressure sensor in the pressure detection tube increases, thereby determining the water depth of the device and the vehicle.

[0015] S2. When the aircraft is moving, water on both sides will pass through the flow detection tube. When water flows inside the flow detection tube, the speed of the aircraft can be determined based on the Bernoulli theorem, which states that the greater the flow rate, the smaller the pressure, and the smaller the flow rate, the greater the pressure.

[0016] Furthermore, the underwater vehicle ballast system includes the following working steps:

[0017] S1. Before use, quickly load up to three ballast blocks through the loading assembly to complete the pre-assembly;

[0018] S2. During the dive, water is pumped into the ballast blocks through a bidirectional pump. The water enters the ballast blocks and squeezes the middle baffles to compress the air inside, thereby increasing the weight of the device and assisting the dive. Depending on the needs of different diving depths, the number of ballast blocks can be filled to achieve a graded ballast effect.

[0019] S3. When it is necessary to float, most of the water in the ballast chamber can be drained through the two-way pump. At the same time, the middle partition can squeeze toward both sides and provide buoyancy inside the ballast block again. This effect can enable the device to quickly restore buoyancy and float;

[0020] S4. When rapid ascent is required in deep water, the loading assembly can be quickly rotated in the reverse direction and the ballast block can be quickly separated from the ballast chamber. In this process, the effect of high-speed weight reduction and increased buoyancy can be achieved, and the weight can be quickly reduced when facing rapid detachment from deep water.

[0021] The present invention provides a ballast system for underwater vehicles, which has the following beneficial effects:

[0022] The advantage of the present invention is that the buoyancy is controlled by the ballast assembly according to the difference between shallow water areas and deep water areas, and the weight, sinking amplitude and floating speed are changed by pouring different numbers of ballast blocks, which can provide good adaptability. At the same time, the loading assemblies cooperate with each other, and while being quickly fixed and installed, the weight can also be quickly reduced and floated when rapid floating is required, thereby improving the emergency response capability of the device.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0034] The present application provides an underwater vehicle ballast system. This system utilizes ballast components to control buoyancy for shallow and deep waters. By injecting different numbers of ballast blocks, the weight, sinking amplitude, and surfacing speed can be varied, providing excellent adaptability. Furthermore, the coordinated loading components allow for rapid installation and, when rapid surfacing is required, rapid weight reduction and surfacing, enhancing the system's emergency response capabilities. The following describes this underwater vehicle ballast system in detail. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments.

[0035] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] See also Figure 1-8 In Example 1

[0037] The present embodiment provides a ballast system for an underwater vehicle, comprising: a main body 1, wherein a loading chamber 2 is provided inside the main body 1, and a plurality of detachable ballast blocks 3 are provided inside the loading chamber 2; a ballast assembly, arranged inside the loading chamber 2 and the ballast blocks 3, and used to cooperate with the ballast blocks 3 to perform pressurized diving and water displacement surfacing; a loading assembly, arranged inside the loading chamber 2, and used to fix the plurality of ballast blocks 3; and a detection assembly, arranged on the surface of the main body 1, and used to detect and determine the status of the main body 1 and the entire vehicle, wherein a battery 101 is provided inside the main body 1, and a circuit board 102 is provided at the bottom of the battery 101.

[0038] Furthermore, the ballast assembly includes: a ballast chamber 301 opened inside the ballast block 3, a liquid inlet pipe 302 opened at the top of the ballast block 3, and a liquid outlet pipe 304 opened at the bottom of the ballast block 3, the position of the liquid outlet pipe 304 corresponding to the position between the liquid inlet pipe 302, and the liquid inlet pipe 302 and the liquid outlet pipe 304 are both connected to the interior of the ballast chamber 301; two middle partitions 308 arranged inside the ballast chamber 301, there is a space between the two middle partitions 308, and the two middle partitions 308 are located between the multiple liquid outlet pipes 304; a pump pipe 201 opened at the top of the loading chamber 2, a two-way pump 202 is provided inside the pump pipe 201, and the liquid inlet pipe 302 and the pump pipe 201 are plugged together;

[0039] When the ballast block 3 is in use, the plurality of ballast blocks 3 are plugged into each other, and the liquid inlet pipe 302 on the top of the lower ballast block 3 will be inserted into the liquid outlet pipe 304 of the upper ballast block 3 to connect them. When diving is required, the two-way pump 202 will pump water from the outside through the pump pipe 201. During the pumping process, the water from the outside will enter the device and be loaded through the plurality of ballast chambers 301. When the ballast chamber 301 is filled with water, the middle partition 308 inside the ballast chamber 301 will be squeezed and compressed by the water. The two middle partitions 308 are close to each other, and the air between the two middle partitions 308 is squeezed in the process of approaching to complete the weight increase and sinking. In this principle, the ballast block 3 at the bottom will be filled the fastest, and according to the sinking requirements, fewer ballast blocks 3 and more ballast blocks 3 can be filled to achieve shallow sinking and deep sinking, so that the device can meet the diving needs of different depths.

[0040] When it is necessary to drain water and float, the water inside the ballast chamber 301 is pumped out in the opposite direction by the two-way pump 202. Whenever the water is pumped out, the gas between the two middle partitions 308 will push the middle partitions 308 to move toward the sides. During the movement, the water on both sides will be squeezed and fill the remaining space in the ballast chamber 301, and will continue to be pumped out by the two-way pump 202. In this process, continuous water pumping and drainage can be effectively provided to ensure floating.

[0041] Furthermore, a plurality of guide rods 305 are provided on the top of the liquid outlet pipe 304, and a closing plate 306 is slidably connected between the plurality of guide rods 305, and a plurality of flow openings 303 are provided on both sides of the liquid inlet pipe 302;

[0042] There is no other ballast block 3 plugged in below the ballast block 3 at the bottom. Therefore, the closing plate 306 will be pressed downward on the upper surface of the liquid outlet pipe 304 under the action of gravity and water pressure. At this time, the liquid outlet pipe 304 cannot discharge water. On the contrary, when there is a ballast block 3 below, the liquid inlet pipe 302 on the top of the lower ballast block 3 will push the closing plate 306 to move upward. At this time, there will be a gap between the closing plate 306 and the liquid outlet pipe 304, and the water will enter the liquid inlet pipe 302 through the flow ports 303 on both sides of the liquid inlet pipe 302, thereby realizing backflow. Under this principle, the water inside the ballast block 3 at the bottom will not flow away easily.

[0043] Furthermore, a closing spring 307 is provided between the top of the closing plate 306 and the guide rod 305, and the closing spring 307 is sleeved on the outer surface of the guide rod 305. During use, the closing spring 307 can push the closing plate 306 to move downward and block the liquid outlet pipe 304, thereby improving the closing stability of the closing plate 306.

[0044] Furthermore, limiting grooves 310 are provided on the top and bottom inner walls of the ballast chamber 301, and limiting blocks 309 are provided on the top and bottom of the middle partition 308, and the limiting blocks 309 are slidably connected to the limiting grooves 310. During use, the two middle partitions 308 are used to achieve air isolation and compression, and the limiting blocks 309 and the limiting grooves 310 can prevent the middle partition 308 from tilting and sliding, resulting in air leakage, etc., thereby improving the stability of the device.

[0045] Furthermore, the detection assembly includes: a plurality of pressure detection tubes 103 provided on the surface of the main body 1, and the plurality of pressure detection tubes 103 located on the same side are distributed in a fan-shaped structure; a plurality of arc-shaped flow rate detection tubes 104 provided on the surface of the main body 1, and the flow rate detection tubes 104 are provided through the surface of the main body 1; a plurality of pressure sensors 105 respectively provided inside the pressure detection tubes 103 and on the inner walls of both sides of the flow rate detection tubes 104;

[0046] The detection component process is as follows:

[0047] S1. Water from the surrounding environment is poured into the pressure detection tube 103. As the device dives deeper, the pressure detected by the pressure sensor 105 in the pressure detection tube 103 increases, thereby determining the water depth of the device and the vehicle.

[0048] S2. When the aircraft is moving, water on both sides will pass through the flow velocity detection tube 104. When water flows inside the flow velocity detection tube 104, the aircraft's moving speed can be determined based on Bernoulli's theorem, which states that the greater the flow velocity, the lower the pressure, while the smaller the flow velocity, the higher the pressure.

[0049] Through the above process, the navigation depth and navigation speed of the aircraft can be judged and quickly fed back to the circuit board 102 and the aircraft console, making it convenient for the user to control the device more accurately.

[0050] Example 2

[0051] Based on Example 1, the loading assembly includes: a driving groove 203 formed on the inner walls of both sides of the loading chamber 2; a driving motor 204 provided on the inner wall of the top of the driving groove 203; a driving rod 205 connected to the bottom of the driving motor 204 via a driving shaft; a driving block 4 provided on both sides of the ballast block 3, and the driving rod 205 is threadedly engaged with the driving block 4;

[0052] During use, the drive motor 204 can drive the drive rod 205 to rotate rapidly, and the ballast block 3 can be quickly connected and installed by utilizing the threaded engagement connection between the rotating drive rod 205 and the drive block 4. During deep navigation, when it is necessary to increase the surfacing speed of the vehicle, it is only necessary to reversely rotate the drive motor 204 and engage the drive block 4 to allow the drive block 4 and the ballast block 3 to quickly fall off, thereby achieving the effect of rapid weight loss and faster floating, and increasing the floating speed of the device when responding to emergencies.

[0053] Furthermore, a fixing groove 401 is provided on the inner wall of the driving block 4, and a plurality of receiving openings 206 are provided on the surface of the driving rod 205. A fixing block 207 is slidably connected to the inside of the receiving opening 206, and a fixing spring 208 is provided between the fixing block 207 and the receiving opening 206, and the surface of the fixing block 207 is arranged in an arc-shaped structure; during use, the arc-shaped fixing block 207 can prevent the fixing block 207 from getting stuck in the driving rod 205 and making it difficult to rotate. When the driving rod 205 is rotated and inserted, the edge of the fixing block 207 will quickly fit with the edge of the driving block 4 and squeeze it with the arc structure, so that the fixing block 207 can squeeze the fixing spring 208 into The receiving port 206 facilitates the insertion of the driving rod 205. When the driving rod 205 is fixed to the driving block 4 and the driving block 4 reaches the fixed position, the fixing block 207 will be pushed by the fixing spring 208 to engage with the fixing groove 401 to complete the rapid fixed installation and prevent it from falling off. When the driving rod 205 rotates again, it can quickly drive the fixing block 207 to rotate, and the edge of the rotating fixing block 207 will contact the edge of the fixing groove 401. During the contact process, the arc-shaped edge is used to compress again and shrink toward the inside of the receiving port 206 to facilitate disengagement. Using the above principle, the fixing block 207 can improve the installation stability of the device to prevent it from falling off.

[0054] Furthermore, the underwater vehicle ballast system includes the following working steps:

[0055] S1. Before use, quickly load up to three ballast blocks 3 through the loading assembly to complete the pre-assembly;

[0056] S2. During the dive, water is filled into the ballast blocks 3 via the bidirectional pump 202. The water enters the ballast blocks and squeezes the middle baffles 308, compressing the air inside. This increases the weight of the device and assists in diving. Depending on the required diving depth, different numbers of ballast blocks 3 can be added to achieve a graded ballast effect.

[0057] S3. When it is necessary to float, most of the water in the ballast chamber 301 can be drained by the two-way pump 202. At the same time, the middle partition 308 can squeeze toward both sides and provide buoyancy inside the ballast block 3 again. This effect can enable the device to quickly restore buoyancy and float;

[0058] S4. When rapid ascent is required in deep water, the loading assembly can be quickly rotated in the reverse direction and the ballast block 3 can be quickly separated from the ballast chamber 301. In this process, the effect of high-speed weight reduction and increased buoyancy can be achieved, and the weight can be quickly reduced when quickly escaping from deep water.
