Description

Technical Field

[0001] The present invention relates to the technical field of manned submersibles, in particular to a manned submersible balance and pitch automatic adjustment device and adjustment method. Background Art

[0002] The most energy-saving state for a manned submersible when sailing underwater is when the submersible's weight and buoyancy are balanced and the submersible's pitch angle is 0 degrees. In the prior art, the submersible's balance and pitch adjustment are achieved through an adjustable ballast system and a pitch adjustment system, respectively.

[0003] Since the number of people (or weight of people) carried on each dive of manned submersibles, especially large and medium-sized manned submersibles with a large number of passengers, varies, in order to achieve the overall balance of the submersible, the amount of water adjusted by the adjustable ballast system each time is also different; the existing adjustment method is: first weigh each person entering the manned submersible, add up the total weight to obtain the total weight of the people on board, and then manually calculate the amount of water that needs to be injected into the adjustable ballast water tank.

[0004] Since adjustable ballast water tanks are respectively provided at the bow and stern of the submersible, the water volume at the bow and stern can be further adjusted according to actual needs to adjust the trim after launching; the specific method is: after the submersible dives underwater, first read the trim angle according to the trim angle instrument, and then use the trim adjustment pump to adjust the water volume in the bow and stern total trim adjustment tanks to achieve the submersible's 0-degree trim angle. Due to the lag of the trim angle instrument number relative to the total trim adjustment pump, it is generally necessary to adjust the trim multiple times to reach a 0-degree trim angle.

[0005] The above-mentioned method for adjusting the balance and pitch of the submersible is time-consuming and labor-intensive, especially for medium and large manned submersibles with a large number of people. More people's weights need to be counted, and it is also very easy to make mistakes. In addition, for some passengers, there is a risk of resisting weighing to prevent the privacy of their weight from being leaked. Summary of the Invention

[0006] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides a rationally structured manned submersible balance and pitch automatic adjustment device and adjustment method, thereby realizing the automated synchronous adjustment of the submersible balance and pitch, saving time and labor, achieving good results, and greatly facilitating actual use.

[0007] The technical solutions adopted in the present invention are as follows:

[0008] A device for automatically adjusting balance and longitudinal tilt of a manned submersible comprises a pressure-resistant shell in which a plurality of seats for passengers are installed. A pressure sensor is installed on the bottom of each seat for detecting the weight of the passengers on the seat. Ballast water tanks are also provided one by one directly below each seat. For each seat, the sum of the weight of the passengers on the seat and the amount of water in the ballast water tank below is a preset value that is equal. The device also comprises a water supply and drainage assembly for supplying water to and draining water from each ballast water tank. The water supply and drainage assembly and each pressure sensor are electrically connected to a remote control assembly.

[0009] As a further improvement of the above technical solution:

[0010] After the passenger sits on the seat, the passenger's center of gravity and the center of gravity of the ballast water tank below the corresponding seat are located in the same longitudinal direction.

[0011] A cab and a passenger cabin are arranged in the pressure-resistant shell. A remote control component is installed in the cab for the driver to operate; and seats for passengers are arranged in order in the passenger cabin.

[0012] An observation window is installed on the pressure hull located directly in front of the passengers.

[0013] A floor is provided in the pressure-resistant shell, forming two spaces, upper and lower. The seats are installed in the space above the floor, the water supply and drainage components are arranged in the space below the floor, and the ballast water tank is located in the space below the floor or at the bottom of the outer wall of the pressure-resistant shell.

[0014] One or more passengers sit on a single seat.

[0015] The water supply and drainage components are connected to a main pipeline, which is arranged under each seat and communicates with each ballast water tank via branch pipelines.

[0016] An electronic flow meter and a solenoid valve f are installed in series on each branch pipe; a liquid level sensor is installed in each ballast water tank, which monitors the liquid level in the ballast water tank in real time and feeds back the corresponding liquid level information to the remote control component.

[0017] The structure of the water supply and drainage component is as follows: it includes a pump component, which is connected to the water inlet pipe and the drainage pipe at the same time. The water inlet pipe at both ends of the pump component is respectively connected in series with a solenoid valve b and a solenoid valve d, and the drainage pipe at both ends of the pump component is respectively connected in series with a solenoid valve a and a solenoid valve c. One end of the water inlet pipe and one end of the drainage pipe are respectively connected to the main pipe, and the other end of the water inlet pipe and the other end of the drainage pipe are respectively connected to the sea pipe connected to the external seawater. A filter, a solenoid valve e and a stop valve are installed in series on the sea pipe from the inside to the outside.

[0018] A method for adjusting the equalization and pitch automatic adjustment device of a manned submersible comprises the following steps:

[0019] After all passengers have entered the cabin, the cabin door will be closed and an announcement will be made asking all passengers to take their seats.

[0020] The driver opens the solenoid valve e through the remote control component and activates the button corresponding to the equalization and pitch automatic adjustment device;

[0021] The pressure sensors located on the bottom of each seat start working, weighing the passengers in the corresponding seats and feeding the weighing data back to the remote control component;

[0022] The remote control component receives the weight of the passengers on each seat and calculates the amount of water required in the corresponding ballast tank;

[0023] Combined with the feedback information from the liquid level sensor in the ballast water tank, the remote control component calculates the amount of water that needs to be added or discharged in the corresponding ballast water tank;

[0024] The water supply and drainage components work, and the electronic flow meters and solenoid valves f on each branch pipe are started synchronously;

[0025] The water supply and drainage components are combined with the opening and closing of the solenoid valve f to supply or drain water to the corresponding ballast water tanks through each branch pipeline until the water volume in the ballast water tank reaches the corresponding calculated value as fed back by the corresponding electronic flow meter and liquid level sensor; then the automatic adjustment ends.

[0026] The beneficial effects of the present invention are as follows:

[0027] The present invention has a compact and reasonable structure and is easy to operate. By weighing the passengers on the seats and supplying and draining water to each ballast water tank, the sum of the weight of the passengers on the corresponding seats and the weight of the water in the ballast water tank below is equal to and consistent with the preset value, thereby making the manned submersible balanced as a whole and presenting a longitudinal inclination angle of 0, realizing automatic and synchronous adjustment of the balance and longitudinal inclination of the submersible, saving time and effort, having good effects, and greatly facilitating actual use.

[0039] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figure 1 and Figure 2 As shown, the present embodiment is a manned submersible equalization and longitudinal tilt automatic adjustment device, including a pressure-resistant shell 2, in which a plurality of seats 8 for passengers 1 are installed, and a pressure sensor 9 is installed on the bottom of each seat 8, which detects the weight of the passenger 1 on the seat 8. A ballast water tank 5 is also provided one by one directly below each seat 8; for a single seat 8, the weight of the passenger 1 on the seat 8 and the sum of the water volume in the ballast water tank 5 below are equal to a preset value; and it also includes a water supply and drainage component 4 for supplying water to each ballast water tank 5, and the water supply and drainage component 4 and each pressure sensor 9 are electrically connected to the remote control component 3.

[0041] In this embodiment, by weighing the passenger 1 on the seat 8 and supplying and draining water to each ballast water tank 5, the sum of the weight of the passenger 1 on the corresponding seat 8 and the weight of the water in the ballast water tank 5 below is equal and consistent with the preset value, so that the manned submersible is balanced as a whole and is in a state of longitudinal inclination angle of 0, realizing automatic synchronous adjustment of the submersible's balance and longitudinal inclination.

[0042] Since the weight of the passengers 1 on each seat 8 is different, in order to achieve a balanced state of the submersible and a 0-degree longitudinal tilt angle, the water filling amount in the adjustable ballast tank 5 under the seat 8 is also different.

[0043] After passenger 1 sits on seat 8, the center of gravity of passenger 1 and the center of gravity of the ballast water tank 5 under the corresponding seat 8 are located in the same longitudinal direction, so that the sum of the weight of the corresponding passenger 1 and the weight of the water in the ballast water tank 5 reaches the preset value, effectively ensuring that the manned submersible is in a balanced state, and can also simultaneously ensure that the longitudinal inclination of the manned submersible is 0, that is, the equilibrium and longitudinal balance state are achieved simultaneously.

[0044] A cab 21 and a passenger cabin 22 are provided in the pressure-resistant shell 2 . The remote control assembly 3 is installed in the cab 21 for the driver to operate. Seats 8 for passengers 1 are arranged in order in the passenger cabin 22 .

[0045] In actual applications, the positions of the cab 21 and the passenger cabin 22, their proportion relative to the area of ​​the manned submersible, etc. can all be designed according to actual needs; the arrangement of the seats 8 in the passenger cabin 22 can also be designed according to actual needs; after the layout design of the cab 21 and the passenger cabin 22 is completed, the sum of the weight of the passenger 1 at the corresponding seat 8 and the weight of the water in the ballast water tank 5 is obtained according to the equilibrium condition, that is, the preset value is calculated.

[0046] An observation window 24 is provided on the pressure-resistant shell 2 located directly in front of the passenger 1 , through which the passenger 1 can observe outside.

[0047] A floor 23 is provided in the pressure-resistant shell 2, forming two relatively independent spaces above and below. The seat 8 is installed in the space above the floor 23, the water supply and drainage assembly 4 is provided in the space below the floor 23, and the ballast water tank 5 is located in the space below the floor 23 or at the bottom of the outer wall of the pressure-resistant shell 2.

[0048] The ballast water tank 5 can be set inside the pressure hull 2 ​​to maintain the overall appearance of the manned submersible, or it can be set outside the pressure hull 2 ​​to solve the problem of cramped space inside the pressure hull 2.

[0049] A single seat 8 carries one or more passengers 1 .

[0050] In this embodiment, the pressure sensor 9 under a single seat 8 is used to weigh the weight of all passengers 1 above the seat 8 , and does not limit a single seat 8 to correspond to only one passenger 1 .

[0051] In practical applications, the limit on the number of passengers 1 on a single seat 8 can be designed and determined based on the situation of the manned submersible and the size of the seat 8 .

[0052] The water supply and drainage assembly 4 is connected to a main pipeline 6 , which is arranged under each seat 8 . The main pipeline 6 is connected to each ballast water tank 5 via a branch pipeline 7 .

[0053] In this embodiment, water is supplied from the water supply and drainage component 4 to the corresponding ballast water tank 5 via the main pipeline 6 and the branch pipeline 7. For drainage, the opposite is true, and the ballast water tank 5 is drained out from the water supply and drainage component 4 through the branch pipeline 7 and the main pipeline 6 in turn.

[0054] like Figure 3 As shown, an electronic flow meter 71 and a solenoid valve f72 are installed in series on each branch pipe 7; a liquid level sensor is installed in each ballast water tank 5, which monitors the liquid level in the ballast water tank 5 in real time and feeds back the corresponding liquid level information to the remote control component 3.

[0055] In actual use, the ballast water tank 5 can be matched with whether to supply or drain water according to the respective needs of water supply or drainage of each ballast water tank 5, through the corresponding water supply or drainage operation of the water supply and drainage component 4, combined with the connectivity of the corresponding branch pipeline 7, such as the on or off of the solenoid valve f72.

[0056] When supplying or draining water to the ballast water tank 5, on the one hand, the electronic flow meter 71 detects the amount of water flowing through and feeds it back to the remote control component 3, and on the other hand, the liquid level sensor in the ballast water tank 5 can also provide real-time feedback on the current water level.

[0057] like Figure 3 As shown, the structure of the water supply and drainage component 4 is: it includes a pump component 41, the pump component 41 is connected to the water inlet pipe and the drainage pipe at the same time, the water inlet pipe at both ends of the pump component 41 is respectively connected in series with a solenoid valve b43 and a solenoid valve d45, the drainage pipe at both ends of the pump component 41 is respectively connected in series with a solenoid valve a42 and a solenoid valve c44, one end of the water inlet pipe and one end of the drainage pipe are respectively connected to the main pipe 6, the other end of the water inlet pipe and the other end of the drainage pipe are respectively connected to the sea pipe connected to the external seawater, and a filter 46, a solenoid valve e47 and a stop valve 48 are installed in series on the sea pipe from the inside to the outside.

[0058] like Figure 4 As shown, when water supply is needed, the solenoid valve b43 and the solenoid valve d45 are in the closed state, the solenoid valve a42 and the solenoid valve c44 are in the open state, and under the power of the pump assembly 41, the external seawater flows into the main pipeline 6 through the water inlet pipeline to supply water to the corresponding ballast water tank 5;

[0059] like Figure 5 As shown, when drainage is required, solenoid valve b43 and solenoid valve d45 are in the disconnected state, and solenoid valve a42 and solenoid valve c44 are in the closed state. Under the power of the pump assembly 41, the water in the corresponding ballast water tank 5 connected by the branch pipe 7 flows into the external seawater through the drainage pipe to achieve drainage.

[0060] In this embodiment, the remote control component 3 serves as the master control system, which is electrically connected to the action and detection components including the water supply and drainage component 4, the pressure sensor 9, the liquid level sensor in the ballast water tank 5, and the electronic flow meter 71 and the solenoid valve f72 on the branch pipe 7, receives detection signals, and sends and controls actions; the remote control component 3 can also include an operation panel to facilitate the driver's input and use.

[0061] like Figure 6 As shown, the adjustment method of the equalization and pitch automatic adjustment device of the manned submersible of this embodiment includes the following steps:

[0062] After all passengers 1 have entered the cabin 22, the cabin door is closed and an announcement is made to invite all passengers 1 to take their seats 8;

[0063] The driver opens the solenoid valve e47 via the remote control assembly 3 and activates the corresponding button of the equalization and pitch automatic adjustment device;

[0064] The pressure sensor 9 located on the bottom surface of each seat 8 starts working, weighs the passenger 1 on the corresponding seat 8, and feeds the weighing data back to the remote control component 3;

[0065] The remote control component 3 receives the weight of the passenger 1 on each seat 8 and calculates the amount of water required in the corresponding ballast tank 5;

[0066] Combined with the feedback information from the liquid level sensor in the ballast water tank 5, the remote control component 3 calculates the amount of water that needs to be added or discharged in the corresponding ballast water tank 5;

[0067] The water supply and drainage assembly 4 works, synchronously starting the electronic flow meter 71 and the solenoid valve f72 on each branch pipe 7;

[0068] The water supply and drainage assembly 4 is combined with the opening and closing of the solenoid valve f72 to supply or discharge water to the corresponding ballast water tank 5 through each branch pipe 7 until the water volume in the ballast water tank 5 reaches the corresponding calculated value as fed back by the corresponding electronic flow meter 71 and liquid level sensor; the automatic adjustment ends.

[0069] like Figure 7 As shown, the adjustment method is further described as follows:

[0070] Assume that the sum of the weight of the passengers on the seats and the amount of water in the ballast water tank is preset to M, and the manned submersible is provided with seats 1, 2, 3, ..., and correspondingly with pressure sensors 1, 2, 3, ..., and after the passengers are seated, the pressure sensors weigh the passengers on the corresponding seats, and obtain the weights of the passengers on each seat as weight M1, weight M2, weight M3, ..., respectively. Then, the amount of water required in the corresponding ballast water tank can be calculated as M-M1, M-M2, M-M3, ..., and if the ballast water tanks are all empty, the water supply and drainage component 4 supplies water to each ballast water tank respectively. M-M1, M-M2, M-M3...; of course, the amount of water in the ballast water tank can be obtained through the information feedback of the liquid level sensor. If there is already some water in the ballast water tank before water supply, the subsequent water supply needs to subtract the existing water amount; the actual water supply can be obtained by detecting the corresponding flow meter on the branch pipe, and the real-time water amount in the ballast water tank can be obtained according to the feedback information of the liquid level sensor; until each ballast water tank carries the required amount of water, that is, M-M1, M-M2, M-M3..., at this time, the solenoid valves f on the branch pipe are all in the closed state, and the adjustment is completed.

[0071] The present invention realizes the automatic synchronous adjustment of the submersible's balance and pitch, saves time and labor, has good effects, and is greatly convenient for actual use.
