Description

Technical Field

[0001] The present invention relates to the technical field of special computers, and particularly to an underwater computer based on a sealing structure. Background Art

[0002] With the continuous development and popularization of computer technology, the requirements for the performance of special computers in harsh environments are getting higher and higher, requiring excellent sealing, shock resistance, and heat dissipation performance to adapt to applications in environments such as national defense technology, industrial sites, and ocean exploration. As a type of special computer, an underwater special computer needs to work underwater for a long time, requiring particularly high waterproof sealing performance, heat dissipation performance, and shock resistance, and has become a leading product in the high-tech industry with its highly reliable protection design and advanced technology.

[0003] In an underwater environment, such as underwater survey, it is necessary to record information or conduct real-time survey on various position areas underwater. When recording and surveying, it is necessary to input data information and adjust parameters. Therefore, an input panel and other information input areas are required. However, when the input panel in the underwater environment moves with the surveyor underwater, it is easy to collide with underwater debris. Therefore, it is necessary to provide safety protection for the input panel.

[0004] Usually, in order to protect the input panel, a protective cover is often installed. However, after the information is recorded or the parameters are input and the protective cover is closed to protect the input panel, a large amount of water will accumulate in the space formed by the protective cover and the area where the input panel is located, causing the input panel to be soaked in water for a long time, damaging the input panel and severely affecting the response speed of the input panel.

[0005] For the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

The threaded block penetrates and is threadedly connected with a screw rod. One end of the screw rod is rotatably installed on the inner wall of the upper housing, and the other end is fixedly installed with a driving motor, and the driving motor is fixedly installed on the inner wall of the upper housing.

[0015] Preferably, a sealing column strip is opened on one side of the sealing plate away from the threaded block, a sealing groove is opened at a position corresponding to the sealing column strip on one side of the installation groove, a sealing column seat corresponding to the sealing column strip is slidably installed in the sealing groove, and a plurality of pressurizing springs are arranged between the sealing column seat and the sealing groove. Both ends of the pressurizing spring are fixedly installed on the sealing column seat and the sealing groove respectively, so that the pressurizing spring deforms along the moving direction of the sealing plate.

[0016] Preferably, the water pumping assembly includes a water pumping tank fixedly installed on the inner wall of the upper housing. A check valve I is fixedly installed at the water inlet of the water pumping tank. The water outlet of the check valve I is connected to the water inlet of the water pumping tank, and the water inlet of the check valve I is communicated with the sealing cavity through a pipeline I;

[0017] A check valve II is arranged at the water outlet of the water pumping tank, and the water inlet of the check valve II is connected to the water outlet of the water pumping tank.

[0020] Preferably, the input panel is inclined in the installation groove, and the distance from the end of the upper surface of the input panel close to the water pumping assembly to the upper surface of the installation groove is greater than the distance from the other end to the upper surface of the installation groove.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides an underwater computer based on a sealing structure, having the following beneficial effects:

[0023] 1. By rotating the protective cover, the protective cover provides safety protection for the sealing plate to prevent the input panel from being deformed by impact, resulting in its inability to be opened and affecting the use of the input panel. At the same time, by using the rotation of the protective cover, the protective cover drives the water pumping assembly to start releasing space, thereby forming a negative pressure. Since the water pumping assembly is communicated with the sealing cavity, when the water pumping assembly releases space to form a negative pressure, the water in the sealing cavity is pumped out by using the negative pressure, thus realizing that the protective cover drives the water pumping assembly to drain the sealing cavity (i.e., the installation area of the input panel) formed by the sealing plate and the installation groove, avoiding damage to the input panel caused by long-term immersion after underwater use and severely affecting the response speed of the input panel.

[0024] 2. During the process of forming a sealing cavity by translating the sealing plate in the present invention, after the sealing column bars on the sealing plate are in contact with the sealing column seats, at this time, the side of the sealing plate close to the sealing column bars has not yet been in contact with the surface of the installation groove. As the sealing plate continues to move until the side of the sealing plate close to the sealing column bars is in contact with the surface of the installation groove, the sealing column bars squeeze the sealing column seats, causing the pressurizing spring to compress and deform, thereby forming an elastic force. The elastic force of the pressurizing spring acts on the sealing column seats in the opposite direction, forming a squeezing force between the sealing column seats and the sealing column bars, thus improving the sealing effect between the two.

[0025] 3. Through the sliding fit between the arc-shaped sealing strip and the arc-shaped sliding groove in the present invention, while guiding and positioning the sliding of the sealing plate, the sealing performance between the two sides of the sealing plate and the installation groove is enhanced by increasing the contact area, preventing water from entering the upper housing through the connection between the side of the sealing plate and the installation groove, so as to improve the sealing performance when not in use underwater.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an underwater computer based on a sealing structure.

[0036] Please refer to Figures 1 - 7 , an underwater computer based on a sealing structure, including an upper housing 1. One end of the upper housing 1 is provided with an installation groove 2. The bottom of the installation groove 2 is provided with an input panel 3. One end of the installation groove 2 is hinged with a protective cover 4. One side of the upper part of the installation groove 2 is penetrated and slidably installed with a sealing plate 5. The installation groove 2 is attached to the sealing plate 5 to form a sealing cavity. Both sides of the inner wall of the upper housing 1 are fixedly installed with water pumping components 6. The water pumping components 6 are communicated with the sealing cavity to pump out the water in the sealing cavity;

[0037] When the protective cover 4 rotates to a set angle threshold relative to the upper surface of the installation groove 2 to release the protection of the sealing plate 5 (that is, when the protective cover 4 is opened), the protective cover 4 synchronously drives the water pumping component 6 to compress the space of the water pumping tank 601 in the water pumping component 6; when the protective cover 4 rotates to be parallel to the upper surface of the installation groove 2 to form the protection of the sealing plate 5 (that is, when the protective cover 4 is closed), the protective cover 4 synchronously drives the water pumping component 6 to release the space of the water pumping tank 601 in the water pumping component 6 to form a negative pressure in the water pumping tank 601.

[0038] When the computer is used underwater, when the user inputs data or adjusts parameters, it is used in the following order. First, the protective cover 4 is opened to release the protection of the sealing plate 5, and then the sealing plate 5 is opened to expose the input panel 3 in front of the user. Subsequently, the user uses the input panel 3 to input underwater data or adjust parameters. After use, first the sealing plate 5 is closed to make the input panel 3 in a sealed space, and then the protective cover 4 is closed.

[0039] When the protective cover 4 is opened, the protective cover 4 rotates around the hinge point, thereby driving the water pumping assembly 6 to compress the space to prepare for the formation of negative pressure. Subsequently, after the sealing plate 5 is opened, since the computer is underwater, water quickly enters the installation groove 2, making the input panel 3 underwater. When the user inputs data or adjusts parameters and then closes the sealing plate 5 again, there is water in the sealing cavity formed by the sealing plate 5 and the inner wall of the installation groove 2, and the input panel 3 is also in this sealing cavity and is soaked by water. At this time, when the protective cover 4 is closed, the protective cover 4 drives the water pumping assembly 6 to start releasing the space, thereby forming negative pressure. Since the water pumping assembly 6 is connected to this sealing cavity, when the water pumping assembly 6 releases the space to form negative pressure, the water in the sealing cavity is pumped out by using the negative pressure, avoiding damage to the input panel 3 caused by long-term soaking and severely affecting the response speed of the input panel 3.

[0040] In addition, when the traditional single sealing plate 5 (i.e., the protective cover mentioned in the background art) protects the input panel 3, since the computer is underwater, when the user moves underwater, there is a risk that the sealing plate 5 will be collided by hard substances underwater, resulting in deformation of the sealing plate 5 and inability to open, affecting the use of the input panel 3.

[0041] In the present invention, by rotating the protective cover 4, the protective cover 4 safely protects the sealing plate 5 to prevent the input panel 3 from being deformed by impact and unable to open, affecting the use of the input panel 3. At the same time, by using the rotation of the protective cover 4, the water pumping assembly 6 is driven to drain the sealing cavity (i.e., the installation area of the input panel 3) formed by the sealing plate 5 and the installation groove 2, avoiding damage to the input panel 3 caused by long-term soaking after underwater use and severely affecting the response speed of the input panel 3.

[0042] Furthermore, for the above-mentioned installation groove 2, one end of the installation groove 2 is provided with a hinge seat 7, the hinge seat 7 is hinged to the protective cover 4, and the protective cover 4 is sealed and installed on the hinge seat 7. A driving motor 8 is fixedly installed on the hinge seat 7 through the rotation axis of the protective cover 4 penetrating the hinge seat 7.

[0043] In the present invention, the rotation of the protective cover 4 when it is opened is defined as forward rotation, and the rotation when it is closed is defined as reverse rotation;

[0044] The driving motor 8 drives the protective cover 4 to perform forward and reverse rotation movements to realize the opening and closing of the protective cover 4.

[0045] Further, for the above-mentioned installation groove 2, arc-shaped slide grooves 9 are provided on the upper parts of both sides of the installation groove 2, and the arc-shaped slide grooves 9 are communicated with the inner cavity of the upper shell 1, and arc-shaped sealing strips 10 are fixedly installed on both sides of the sealing plate 5, and the arc-shaped sealing strips 10 are slidably matched with the arc-shaped slide grooves 9;

[0046] The lower surface of the sealing plate 5 is located at one end of the inner cavity of the upper shell 1, and a threaded block 11 is fixedly installed. The threaded block 11 passes through and is threadedly connected with a screw 12. One end of the screw 12 is rotatably installed on the inner wall of the upper shell 1, and the other end is fixedly installed with a drive motor 13. The drive motor 13 is fixedly installed on the inner wall of the upper shell 1;

[0047] The sliding cooperation between the arc-shaped sealing strip 10 and the arc-shaped slide groove 9 is used to guide and position the sliding of the sealing plate 5, and to enhance the sealing between the two sides of the sealing plate 5 and the mounting groove 2 by increasing the contact area, thereby preventing water from entering the interior of the upper housing 1 from the connection between the side of the sealing plate 5 and the mounting groove 2 and causing water to enter the computer.

[0048] In specific applications, the drive motor 13 is started, and the drive motor 13 drives the screw rod 12 to rotate. Since the screw rod 12 is threadedly connected to the threaded block 11, and the threaded block 11 is fixedly mounted on the sealing plate 5, and the sealing plate 5 is slidingly matched with the arc-shaped sealing strip 10 and the arc-shaped slide groove 9, when the screw rod 12 rotates, the sealing plate 5 is driven by the threaded block 11 to translate under the action of the sliding match between the arc-shaped sealing strip 10 and the arc-shaped slide groove 9, thereby driving the sealing plate 5 to achieve sliding match with the mounting groove 2, thereby achieving the formation and release of the sealing cavity;

[0049] In addition, it should be noted that the formation of the sealed cavity means that the sealing plate 5 is sealed and fitted around the mounting groove 2, while the release of the sealed cavity means that the sealing plate 5 is not located directly above the mounting groove 2, so that the input panel 3 in the mounting groove 2 is exposed to water.

[0050] Further, for the above-mentioned sealing plate 5, a sealing column 14 is provided on one side of the sealing plate 5 away from the threaded block 11, a sealing groove 15 is provided at a position corresponding to the sealing column 14 on one side of the mounting groove 2, a sealing column seat 16 corresponding to the sealing column 14 is slidably installed in the sealing groove 15, a plurality of booster springs 17 are provided between the sealing column seat 16 and the sealing groove 15, and the two ends of the booster spring 17 are respectively fixedly installed on the sealing column seat 16 and the sealing groove 15, so that the booster spring 17 is deformed along the moving direction of the sealing plate 5;

[0051] During the process of the translation plate 5 translating to form a sealed cavity, after the sealing column bars 14 on the translation plate 5 are in contact with the sealing column seats 16, at this time, the side of the translation plate 5 close to the sealing column bars 14 is not yet in contact with the surface of the installation groove 2. As the translation plate 5 continues to move until the side of the translation plate 5 close to the sealing column bars 14 is in contact with the surface of the installation groove 2, the sealing column bars 14 squeeze the sealing column seats 16, causing the pressurizing spring 17 to compress and deform, thereby forming an elastic force. The elastic force of the pressurizing spring 17 acts on the sealing column seats 16 in the opposite direction, causing an extrusion force to be formed between the sealing column seats 16 and the sealing column bars 14, thereby improving the sealing effect between the two.

[0052] Further, for the above-mentioned water pumping assembly 6, the water pumping assembly 6 includes a water pumping tank 601, the water pumping tank 601 is fixedly installed on the inner wall of the upper housing 1, a check valve 602 is fixedly installed at the water inlet of the water pumping tank 601, the water outlet of the check valve 602 is connected to the water inlet of the water pumping tank 601, and the water inlet of the check valve 602 is communicated with the sealed cavity through a pipe 1;

[0053] A check valve 603 is arranged at the water outlet of the water pumping tank 601, and the water inlet of the check valve 603 is connected to the water outlet of the water pumping tank 601. The water outlet of the check valve 603 is communicated with the surface of the upper housing 1 through a pipe 2;

[0054] The setting of the check valve 602 ensures that the water in the sealed cavity can only enter the water pumping tank 601 through the check valve 602, and cannot enter the sealed cavity from the water pumping tank 601. Similarly, the setting of the check valve 603 ensures that the water in the water pumping tank 601 can only be discharged from the water pumping tank 601 through the check valve 603 and flow to the outside of the upper housing 1.

[0055] During the process of the compression and release of the space in the water pumping tank 601, through the limitation of the water flow direction by the check valve 602 and the check valve 603, the water in the sealed cavity is discharged from the body surface of the upper housing 1, thereby ensuring that the sealed cavity remains water-free after use and preventing the input panel 3 from being soaked in water for a long time.

[0056] Further, for the above-mentioned water pumping tank 601, a piston 604 is in sealed sliding fit with the inner wall of the water pumping tank 601. One side of the piston 604 is fixedly installed with a U-shaped driving rod 605. One end of the U-shaped driving rod 605 is fixedly installed with a driving frame 606. The driving frame 606 penetrates and is slidably installed on the upper housing 1. One end of the driving frame 606 is slidably fitted with a power column 18 in a direction perpendicular to the moving direction of the driving frame 606. The power column 18 is hinged to the protective cover 4;

[0057] When the protective cover 4 is opened, the position where the protective cover 4 is hinged to the power column 18 moves in an arc around the rotating shaft of the protective cover 4. Thus, while pulling the power column 18 to move upward relative to the drive frame 606, it moves synchronously along the moving direction of the sealing plate 5. Thereby, the U-shaped drive rod 605 is driven by the drive frame 606 to squeeze the piston 604, causing the piston 604 to move in the water suction tank 601 in the direction close to the sealing cavity, so as to achieve the purpose of compressing the space of the water suction tank 601;

[0058] When the protective cover 4 is closed, the principle is the same as when the protective cover 4 is opened. The drive frame 606 drives the U-shaped drive rod 605 to pull the piston 604, causing the piston 604 to move in the water suction tank 601 in the direction away from the sealing cavity. Thus, a negative pressure is formed in the water suction tank 601, and the water in the sealing cavity is pumped into the water suction tank 601. When the protective cover 4 is opened again, the piston 604 compresses the space in the water suction tank 601 again, so that the water pumped into the water suction tank 601 is discharged out of the upper housing 1 through the check valve II 603.

[0059] Further, for the above-mentioned power column 18, the power column 18 includes an outer column 1801. Earrings 1802 are provided at both ends of the outer column 1801. The earrings 1802 are used to limit the position range of the drive frame 606 on the outer column 1801. An inner column 1804 is slidably fitted to the inner wall of the outer column 1801. A spring 1803 is coaxially sleeved on the inner column 1804. Both ends of the spring 1803 are respectively fixedly installed on the inner wall of the outer column 1801 and one end of the inner column 1804. The protective cover 4 is hinged to the top of the inner column 1804;

[0060] The inner column 1804 and the outer column 1801 are coaxially arranged and slidably fitted. When the outer column 1801 moves upward as the protective cover 4 is opened and the earring 1802 abuts against the drive frame 606, through the sliding fit of the inner column 1804 relative to the outer column 1801, the rotation angle of the protective cover 4 is increased. Thus, the drive frame 606 drives the piston 604 to have an increased moving space in the water suction tank 601 through the drive frame 606 and the U-shaped drive rod 605. Furthermore, the degree of single - time water pumping is improved, ensuring the extraction amount when the piston 604 moves along the inner wall of the water suction tank 601 to form negative - pressure water pumping, so as to ensure that all the water in the sealing cavity is pumped out completely.

[0061] Among them, when the inner column 1804 and the outer column 1801 slide relative to each other, the spring 1803 is compressed to generate elastic force. When the inner column 1804 and the outer column 1801 are reset, the elastic force of the spring 1803 makes their positions reset to the state before relative sliding.

[0062] Further, for the above-mentioned input panel 3, the input panel 3 is inclined in the installation groove 2, and the distance from the end of the upper surface of the input panel 3 close to the water pumping assembly 6 to the upper surface of the installation groove 2 is greater than the distance from the other end to the upper surface of the installation groove 2, so as to avoid water residue on the input panel 3, and make the water converge along the inclined input panel 3 at the position communicated with the water pumping assembly 6, facilitating sufficient extraction.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
