Description

Technical Field

[0001] The present invention relates to the technical field of submersibles, and in particular to a water intake of a submersible. Background Art

[0002] Submersibles cover a wide range, from highly automated small submersibles that can accommodate only one or two people, to large submarines that can carry hundreds of people and have the ability to dive for long periods of time, such as the design of a micro-submarine disclosed in CN106394836B.

[0003] Submersibles typically have one or more ballast tanks, which can be controlled by valves to allow seawater in and out. When the submersible needs to dive, the operator opens the tank's inlet valve, allowing seawater to enter the tank from the inlet. As the amount of seawater in the tank increases, the submersible's total weight increases, exceeding the buoyancy of the submersible, and the submersible begins to dive.

[0004] Submarine water inlets are typically equipped with screens or grids to prevent large objects from entering the water pipes and causing blockage. However, when the water inlet is left unused for long periods, marine organisms can easily attach to the mesh of the screen or grid, causing blockage. For example, if barnacles attach to the mesh, they can quickly become clogged as they grow, affecting the smooth inflow of water into the ballast tanks. Summary of the Invention

[0005] In view of this, the present invention proposes a water suction port of a submersible, which penetrates the water inlet hole by setting a piston structure, which is convenient for cleaning parasites in the water inlet hole and cleaning the inner wall of the water inlet hole, which is beneficial to improving the patency of the water inlet hole when water enters, and further facilitates the smooth water inlet of the ballast water tank.

[0036] (2) By setting the end face of the piston near one end of the water inlet hole to be arc-shaped and concave, and the outer diameter of the piston is equal to the inner diameter of the water inlet hole, when the piston penetrates the water inlet hole, the edge of the end of the piston that penetrates the water inlet hole can be used to remove debris on the inner wall of the water inlet hole, thereby improving the cleaning effect of the water inlet hole.

[0037] (3) By setting up a protective grid, it is convenient to filter foreign matter in the water and effectively prevent the pipe of the ballast water tank from being blocked.

[0047] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0048] like Figure 1-6 As shown, a water intake of a submersible of the present invention includes a submersible shell 1, a connecting sleeve 2, a water pipe joint 3, a piston 4 and a driving mechanism 5.

[0049] The submersible shell 1 is provided with a water inlet 101. Figure 2The cross-section of the water inlet hole 101 shown in the figure is circular, and the piston 4 is cylindrical. In actual applications, the cross-section of the water inlet hole 101 can also be square, triangular or other geometric shapes, and the shape of the piston 4 is adapted according to the cross-sectional shape of the water inlet hole 101.

[0050] One end of the connecting sleeve 2 is fixed to the inner wall of the submersible housing 1 and is connected to the water inlet 101, and the other end is fixedly connected to one end of the driving mechanism 5. Specifically, Figure 1 and Figure 2 As shown, the drive mechanism 5 includes a housing 51. The connecting sleeve 2, housing 51, and submersible housing 1 form an integrated structure, providing high structural strength. Furthermore, flange structures may be used at both ends of the connecting sleeve 2 to connect the submersible housing 1 and the drive mechanism 5, facilitating the installation of the housing 51 of the connecting sleeve 2. These flange structures are not shown in the illustration.

[0051] One end of the water pipe joint 3 is fixed to the side of the connecting sleeve 2 and is connected thereto, and the other end is provided with a flange for connecting to the water supply pipeline of the ballast water tank.

[0052] The piston 4 is slidably sealed on the inner side of the connecting sleeve 2, and one end of the piston 4 is hinged to the output end of the driving mechanism 5. Specifically, the piston 4 and the connecting sleeve 2 form a piston mechanism. The fitting clearance between the piston 4 and the connecting sleeve 2 will not leak water, and the piston 4 can also slide linearly in the connecting sleeve 2.

[0053] The driving mechanism 5 is used to drive the piston 4 to slide back and forth along the axial direction of the connecting sleeve 2, so that the water pipe joint 3 and the connecting sleeve 2 are selectively connected and disconnected, and one end of the piston 4 selectively passes through the water inlet hole 101. Specifically, as Figure 3 As shown, when the ballast water tank needs to be filled with water, the driving mechanism 5 drives the piston 4 to move into the box body 51 to connect the water pipe joint 3 and the connecting sleeve 2. At this time, the water in the water area passes through the water inlet hole 101, the connecting sleeve 2, the water pipe joint 3 in sequence, and finally enters the ballast water tank through the pipeline; when the water inlet stops, as shown in FIG. Figure 5 As shown, the driving mechanism 5 drives one end of the piston 4 to block the water inlet hole 101, so that foreign matter in the water is not easily able to enter the water inlet hole 101; and when the water inlet hole 101 needs to be cleaned, the driving mechanism 5 drives the piston 4 to move back and forth like a piston, and then the foreign matter in the water inlet hole 101 is pushed out of the water inlet hole 101 through the piston 4.

[0054] Since some foreign objects are parasitic, such as barnacles, it is difficult to clean barnacles after they parasitize in the water inlet 101. Therefore, in order to facilitate the cleaning of barnacles, the end face of the piston 4 close to the water inlet 101 is arc-shaped and concave, and the outer diameter of the piston 4 is equal to the inner diameter of the water inlet 101. Through this structure, after one end of the piston 4 enters the water inlet 101, its outer wall can fit with the inner wall of the water inlet 101, so that the edge of the arc-shaped concave structure forms a scraper structure on the inner wall of the water inlet 101. When the piston 4 moves back and forth, the barnacles on the inner wall of the water inlet 101 are removed by the scraper structure.

[0055] In addition, there are many objects such as garbage and fish in the water. In order to prevent these objects from entering the water inlet 101 and causing the water inlet 101 to be blocked, a protective grid 6 is fixed in the water inlet 101 to prevent these objects from entering the water inlet 101.

[0056] There are several through holes 601 evenly distributed on the protective grille 6. During the use of the protective grille 6, the through holes 601 are also easily parasitized by barnacles. Therefore, in order to prevent barnacles from parasitizing in the through holes 601, one end of the piston 4 can selectively penetrate the protective grille 6 to push the barnacles out of the protective grille 6.

[0057] Specifically, such as Figure 3 As shown, a plurality of push rods 402 are formed on one end of the piston 4 near the water inlet 101 through a groove 401. The push rods 402 correspond to the through holes 601 one by one. When the piston 4 moves back and forth, the push rods 402 pass through the corresponding through holes 601 to remove barnacles from the through holes 601 of the protective grid 6. In this structure, Figure 4 As shown, the end of the piston 4 close to the water inlet 101 is flat, and the upper end of the hole wall of the protective grid 6 close to the piston 4 is blade-shaped, that is, the upper end of the hole wall between two adjacent through holes 601 is wedge-shaped, and the wedge-shaped structure forms a blade structure on the upper end of the hole wall between the through holes 601. Figure 4 The direction of the middle arrow is upward, and one end of the piston 4 plane is the lower end. When the piston 4 moves back and forth, the lower end of the piston 4 cooperates with the upper end of the protective grid 6, and the blade structure is used to crush foreign matter between the piston 4 and the protective grid 6. At the same time, the push rod 402 can pass through the corresponding through hole 601 to clear foreign matter in the through hole 601. When the piston 4 is needed to block the water inlet hole 101, the lower end of the push rod 402 is aligned with the lower end of the protective grid 6.

[0058] When the water pipe joint 3 and the connecting sleeve 2 are disconnected, the groove 401 and the water pipe joint 3 are not connected. Specifically, the axial length of the push rod 402 is greater than the hole depth of the through hole 601 and less than the hole depth of the water inlet hole 101. At the same time, the outer diameter of the push rod 402 is equal to the inner diameter of the through hole 601. Therefore, Figure 5As shown, when the piston 4 blocks the water inlet hole 101 , the groove 401 is located inside the water inlet hole 101 , and the side of the piston 4 blocks the connection between the water pipe connector 3 and the connecting sleeve 2 .

[0059] In the above structure, the driving mechanism 5 includes a gear 52, a swing arm 53 and a motor 54, wherein Figure 5 As shown, the box body 51 and the connecting sleeve 2 are fixedly connected, and the end of the connecting sleeve 2 away from the water inlet hole 101 is connected to the box body 51; the gear 52 is rotatably arranged inside the box body 51; one end of the swing arm 53 is hinged to the gear 52, and the other end is hinged to the piston 4; the motor 54 is fixed to the box body 51, and is used to drive the gear 52 to rotate.

[0060] When the piston 4 needs to be moved, the motor 54 drives the gear 52 to rotate, and the gear 52 drives one end of the swing arm 53 to rotate eccentrically, and the other end of the swing arm 53 pulls the piston 4 to move linearly in the connecting sleeve 2.

[0061] To prevent the swing arm 53 from interfering with the piston 4, Figure 5 and 6 As shown, a sink 403 is provided on one end of the piston 4 away from the water inlet hole 101 , and one end of the swing arm 53 is hinged in the sink 403 .

[0062] Typically, multiple water inlet holes 101 are required to increase the water inlet volume, such as Figure 5 As shown, there are several linear arrays of water inlet holes 101, and a connecting sleeve 2 is correspondingly provided at each water inlet hole 101. A piston 4 is provided in each connecting sleeve 2, and a swing arm 53 is hinged on each piston 4, and a gear 52 is hinged on each swing arm 53. Among them, several connecting sleeves 2 are fixed on the box body 51, and two adjacent gears 52 are meshed with each other, and one of the gears 52 is fixedly connected to the output shaft of the motor 54.

[0063] In addition, in order to improve the service life of the components inside the box body 51, an oil inlet 501 is provided on one end of the box body 51, and an oil outlet 502 is provided on the other end. Lubricating oil is injected into the box body 51 through the oil inlet 501 to achieve lubrication. During subsequent maintenance, the lubricating oil in the box body 51 is drained through the oil outlet 502, and then new lubricating oil is injected into the box body 51 through the oil inlet 501.

[0064] During the lubrication process, the piston 4 can impact the lubricating oil during reciprocating motion, making the lubricating oil more easily adhere to the various components in the box body 51, thereby improving the lubrication effect. Furthermore, a plurality of protrusions 404 are provided on the end of the piston 4 away from the water inlet hole 101, and the protrusions 404 are used to cut the lubricating oil and turbulently flow the lubricating oil, thereby improving the lubrication effect.

[0065] The method for using the water intake port of a submersible of the present invention is as follows:

[0066] When the ballast water tank needs to be filled with water, the driving mechanism 5 drives the piston 4 to move toward the box body 51, so that the connecting sleeve 2 and the water pipe joint 3 are connected. At this time, the water in the water area can pass through the water inlet hole 101, the connecting sleeve 2, and the water pipe joint 3 in sequence and enter the ballast water tank. After the water enters, the driving mechanism 5 drives the piston 4 to seal the water inlet hole 101.

[0067] When the water inlet hole 101 needs to be cleaned, the piston 4 is driven to reciprocate by the driving mechanism 5 to clean the water inlet hole 101 . Similarly, the foreign matter in the through hole 601 is cleaned by the push rod 402 .

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
