[0031] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

[0033] At present, unmanned autonomous underwater submersibles are mostly used for deep-sea work far away from human activities, so they need to use satellite communications to achieve data transmission and parameter modification. However, most current underwater submersibles are equipped with fixed rod antennas. In order to meet the needs of satellite communications, the underwater submersibles need to be strictly adjusted to a fixed posture. However, the posture adjustment is difficult, and the rod antenna increases the difficulty of transportation.

[0034] In this regard, the present application proposes an antenna device 100 for an underwater submersible.

[0035] The following is combined with Figure 1-4 An antenna device 100 for an underwater submersible according to an embodiment of the present application is described.

[0036] like Figure 1 As shown, the antenna device 100 for an underwater submersible according to an embodiment of the present application includes: a mounting base 10 and an antenna assembly 20.

[0037] The mounting seat 10 is used to be sealed and connected to the underwater submersible. The antenna assembly 20 includes a rotating rod 21 and a plate-like box body 22. One end of the rotating rod 21 is rotatably mounted on the mounting seat 10 and the other end is connected to the plate-like box body 22. A radiator is provided in the plate-like box body 22. A first wiring space is formed in the rotating rod 21. A cable electrically connected to the radiator is provided in the first wiring space.

[0038] It can be understood that, compared with the rod-shaped antenna in the related art, the radiator in the present application is installed in a plate-shaped box body 22 to form a plate-shaped antenna, and the first routing space in the rotating rod 21 can meet the routing of the cable electrically connected to the radiator to reduce the difficulty of cable routing. At the same time, the rotating rod 21 can provide a sealed first routing space for the routing of the cable (not shown in the figure), thereby enhancing the sealing of the cable.

[0039] Furthermore, the antenna assembly 20 has a first state and a second state. In the first state, Figure 2 As shown, the orthographic projection of the other end of the rotating rod 21 falls on the outside of the mounting seat 10. In the second state, as shown in FIG. Figure 3 As shown, the orthographic projection of the other end of the rotating rod 21 on the mounting seat 10 falls inside the mounting seat 10 .

[0040] It can be understood that, since one end of the rotating rod 21 is rotatably mounted on the mounting seat 10 and the other end is connected to the plate-shaped box body 22, the position of the orthographic projection of the other end of the rotating rod 21 on the mounting seat 10 is different when the antenna assembly 20 is in the first state and the second state. In particular, in the first state, Figure 2 As shown, the orthographic projection of the other end of the rotating rod 21 falls on the outside of the mounting seat 10. In the second state, as shown in FIG. Figure 3 As shown, the orthographic projection of the other end of the rotating rod 21 on the mounting seat 10 falls within the mounting seat 10, so that the distance between the other end of the rotating rod 21 and the mounting seat 10 of the antenna assembly 20 in the first state is greater than the distance between the other end of the rotating rod 21 and the mounting seat 10, that is, the distance between the plate-shaped box body 22 and the mounting seat 10 of the antenna assembly 20 in the first state is greater than the distance between the plate-shaped box body 22 and the mounting seat 10 of the antenna assembly 20 in the second state.

[0041] For example, in the first state, the distance between the plate-shaped box body 22 and the mounting seat 10 is relatively large, which facilitates the communication between the underwater submersible and the satellite. In the second state, the distance between the plate-shaped box body 22 and the mounting seat 10 is relatively small, so that the projection of the antenna device 100 for the underwater submersible in the direction from the rotating rod 21 to the mounting seat 10 is relatively small, so as to reduce the difficulty of transportation.

[0042] Therefore, the present application can drive the plate-shaped box body 22 to rotate relative to the mounting seat 10 through the rotating rod 21 so that the antenna assembly 20 can switch between the first state and the second state, thereby facilitating the posture adjustment of the antenna assembly 20 to meet communication requirements, thereby reducing the posture adjustment requirements of the underwater submersible while meeting satellite communication requirements. In particular, when the antenna assembly 20 is in the second state, the positive projection of the other end of the rotating rod 21 on the mounting seat 10 falls within the mounting seat 10. In this way, the projection of the antenna device 100 for the underwater submersible in the direction from the rotating rod 21 to the mounting seat 10 is smaller, so as to reduce the difficulty of transportation.

[0043] Among them, the connection between the rotating rod 21 and the mounting seat 10 is offset from the geometric center of the mounting seat 10, so that the setting of the rotating rod 21 will not be affected by the geometric shape of the mounting seat 10. For example, when the mounting seat 10 is a regular shape such as a square or a circle, the connection between the rotating rod 21 and the mounting seat 10 is offset from the geometric center of the mounting seat 10, so that when the rotating rod 21 rotates, the antenna assembly 20 must exist in a first state in which the orthographic projection of the other end of the rotating rod 21 falls on the outside of the mounting seat 10 and a second state in which the orthographic projection of the other end of the rotating rod 21 on the mounting seat 10 falls inside the mounting seat 10.

[0044] Therefore, the shape of the mounting base 10 will not affect the two states of the antenna assembly 20 , thereby facilitating reducing the difficulty of installing the antenna device 100 .

[0045] Furthermore, the plane where the plate-shaped box body 22 is located is parallel to the extension direction of the rotation axis of the rotating rod 21. Thus, the space occupied by the plate-shaped box body 22 in the direction perpendicular to the rotation axis of the rotating rod 21 can be reduced, thereby facilitating the reduction of the size of the antenna device 100 in the direction perpendicular to the rotation axis of the rotating rod 21, and at the same time, making the projection surface of the orthographic projection of the plate-shaped box body 22 in the extension direction of the rotation axis of the rotating rod 21 smaller, so as to reduce the difficulty of transportation.

[0046] According to the antenna device 100 for an underwater submersible according to the embodiment of the present application, the rotating rod 21 can drive the plate-shaped box body 22 to rotate relative to the mounting seat 10 so that the antenna assembly 20 can switch between the first state and the second state, thereby facilitating the posture adjustment of the antenna assembly 20 to meet communication requirements, thereby reducing the posture adjustment requirements of the underwater submersible when meeting satellite communication requirements. In particular, when the antenna assembly 20 is in the second state, the positive projection of the other end of the rotating rod 21 on the mounting seat 10 falls within the mounting seat 10. In this way, the projection of the antenna device 100 for an underwater submersible in the direction from the rotating rod 21 to the mounting seat 10 is smaller, so as to reduce the difficulty of transportation.

[0047] In some embodiments, Figure 1 As shown, the mounting seat 10 is constructed as a disc member, and the rotating rod 21 includes a first rod body 211 and a second rod body 212, at least a portion of the first rod body 211 extends along the axial direction of the disc member and is connected to the disc member, and the second rod body 212 extends along the radial direction of the disc member and is connected between the first rod body 211 and the plate-like box body 22; wherein the maximum distance from the connection between the first rod body 211 and the disc member to the edge of the disc member is a first distance, the first distance is greater than the radius of the disc member, and the first distance is the same as the length of the second rod body 212.

[0048] It can be understood that the maximum distance from the connection between the first rod body 211 and the disc member to the edge of the disc member is the first distance, and the first distance is greater than the radius of the disc member, that is, the connection between the first rod body 211 and the disc member is not the center of the disc member. When the first rod body 211 drives the plate-like box body 22 to rotate through the second rod body 212, the different rotation angles of the first rod body 211 can make the distance between the plate-like box body 22 and the mounting seat 10 different, thereby meeting the posture adjustment requirements of the antenna assembly 20.

[0049] For example Figure 2 As shown, when the distance from the plate-shaped box body 22 to the mounting seat 10 is at a maximum value, the antenna assembly 20 is in a first state, at which time, it is convenient to realize the communication between the underwater submersible and the satellite.

[0050] Or Figure 3 As shown, when the distance from the plate-shaped box body 22 to the mounting seat 10 is at a minimum, the line assembly is in the second state. At this time, the projection of the antenna device 100 in the direction from the rotating rod 21 to the mounting seat 10 is smaller, so as to reduce the difficulty of transportation.

[0051] In some embodiments, Figure 1 As shown, the antenna device 100 further includes: a driving member and a connecting rod 40, the connecting rod 40 is disposed through the mounting seat 10, one end of the connecting rod 40 is connected to the driving member and the other end is connected to the rotating rod 21; wherein, Figure 4 As shown, a second wiring space 43 is formed in the connecting rod 40, and the second wiring space 43 is connected to the first wiring space.

[0052] Thus, the power connection between the driving member and the rotating rod 21 can be achieved through the connecting rod 40, so that it is convenient to control the rotation of the rotating rod 21 through the driving member, especially, the cable can continue to be routed along the second routing space 43. Since the mounting seat 10 is sealed and connected to the underwater submersible, and the connecting rod 40 is passed through the mounting seat 10, the cable can be routed along the second routing space 43 to the underwater submersible, thereby reducing the difficulty of routing and facilitating the sealing during routing.

[0053] In some embodiments, the connecting rod 40 is provided with an external thread 42, and the inner wall of the rotating rod 21 is provided with an internal thread, so that the external thread 42 cooperates with the internal thread, so that the connecting rod 40 and the rotating rod 21 are threadedly connected. In this way, it is convenient to enhance the connection stability between the two and help reduce the difficulty of loading and unloading.

[0054] In some embodiments, Figure 1 As shown, the driving member includes a driving motor 31, a first transmission gear 32 is provided at the output end of the driving motor 31, a second transmission gear 33 is fixedly sleeved on the connecting rod 40, and the first transmission gear 32 and the second transmission gear 33 are meshed.

[0055] Thus, the power connection between the output end of the drive motor 31 and the connecting rod 40 can be achieved through the engagement of the first transmission gear 32 and the second transmission gear 33, and the gear transmission method can facilitate the enhancement of the rotation stability of the connecting rod 40, thereby enhancing the rotation stability of the rotating rod 21, and thereby enhancing the stability of the antenna assembly 20 switching between the first state and the second state.

[0056] In some implementations, the radius of the first transmission gear 32 is greater than the radius of the second transmission gear 33 , so that the output end of the drive motor 31 can use a smaller driving force to achieve the rotation of the connecting rod 40 , thereby facilitating reducing the energy consumption of the drive motor 31 .

[0057] In other implementations, the radius of the first transmission gear 32 is smaller than the radius of the second transmission gear 33. In this way, when the second transmission gear 33 is driven by the first transmission gear 32 at the output end of the driving motor 31 to drive the connecting rod 40 to rotate, the rotation angle of the connecting rod 40 can be finely controlled, thereby facilitating improving its control accuracy.

[0058] In some embodiments, Figure 1 As shown, the first transmission gear 32 and the second transmission gear 33 are both bevel gears.

[0059] It can be understood that since the drive motor 31 needs to drive the connecting rod 40 to rotate, if the first transmission gear 32 and the second transmission gear 33 are both set as conventional spur gears, according to the meshing transmission requirements of the spur gears, the output end of the drive motor 31 can only be arranged in a direction that coincides with or is parallel to the axial direction of the connecting rod 40. This will increase the space occupied in the axial direction of the connecting rod 40.

[0060] Therefore, in the present application, by setting the first transmission gear 32 and the second transmission gear 33 as bevel gears, according to the meshing transmission requirements of the bevel gears, the output end of the drive motor 31 can be arranged on the radial side of the connecting rod 40, so that it is convenient to reduce the space occupied by the drive motor 31 in the axial direction of the connecting rod 40, and then it is convenient to reduce the size of the antenna device 100 in the axial direction of the connecting rod 40.

[0061] In some embodiments, Figure 2 and Figure 3 As shown, the mounting seat 10 is provided with a limiting structure, and in the circumferential direction of the connecting rod 40, the limiting structure is used to cooperate with the connecting rod 40 in a limiting manner in the first state and / or the second state.

[0062] For example, the mounting base 10 is provided with a limiting structure, which is on the circumference of the connecting rod 40. The limiting structure is used to cooperate with the connecting rod 40 in the first state, so as to enhance the state stability of the antenna assembly 20 in the first state.

[0063] Alternatively, the mounting base 10 is provided with a limiting structure, which is on the circumference of the connecting rod 40 and is used to cooperate with the connecting rod 40 in the second state, so as to enhance the state stability of the antenna assembly 20 in the second state.

[0064] Alternatively, the mounting seat 10 is provided with a limiting structure, which is on the circumference of the connecting rod 40, and is used to limit and cooperate with the connecting rod 40 in the first state and the second state, so as to facilitate enhancing the state stability of the antenna assembly 20 in the first state and the second state.

[0065] In some implementations, the limiting structure may be a retractable limiting protrusion 11, or a limiting robot, etc., which is not limited here.

[0066] In some embodiments, Figure 2 and Figure 3 As shown, the connecting rod 40 is sleeved with a limiting plate 41, and the limiting structure includes a limiting protrusion 11, as shown in FIG. Figure 4 As shown, the limiting plate 41 has an arcuate surface 411 , a first limiting surface 412 and a second limiting surface 413 . The arcuate surface 411 is disposed around the rotation axis of the connecting rod 40 and connected between the first limiting surface 412 and the second limiting surface 413 .

[0067] like Figure 1 As shown, in the first state, the first limiting surface 412 is limitedly matched with the limiting protrusion 11, as shown in FIG. Figure 2As shown, in the second state, the second limiting surface 413 is limitedly cooperated with the limiting protrusion 11; wherein, the maximum distance from the arc surface 411 to the connecting rod 40 is smaller than the minimum distance from the connecting rod 40 to the limiting protrusion 11, and the maximum distances from the first limiting surface 412 and the second limiting surface 413 to the connecting rod 40 are greater than the minimum distance from the connecting rod 40 to the limiting protrusion 11.

[0068] Therefore, when the arc surface 411 is facing the limiting protrusion 11, since the maximum distance from the arc surface 411 to the connecting rod 40 is less than the minimum distance from the connecting rod 40 to the limiting protrusion 11, the limiting protrusion 11 will not hinder the movement of the arc surface 411 relative to the limiting protrusion 11, and the maximum distances from the first limiting surface 412 and the second limiting surface 413 to the connecting rod 40 are greater than the minimum distance from the connecting rod 40 to the limiting protrusion 11, so that when the connecting rod 40 rotates, the first limiting surface 412 abuts against the limiting protrusion 11, since the maximum distance from the first limiting surface 412 to the connecting rod 40 is greater than the minimum distance from the connecting rod 40 to the limiting protrusion 11, the first limiting surface 412 abuts against the limiting protrusion 11, at this time, the connecting rod 40 cannot continue to rotate, that is, the connecting rod 40 can be relatively stably in the first state, thereby enhancing the structural stability of the antenna assembly 20 in the first state.

[0069] Furthermore, when the second limiting surface 413 abuts against the limiting protrusion 11, since the maximum distance from the second limiting surface 413 to the connecting rod 40 is greater than the minimum distance from the connecting rod 40 to the limiting protrusion 11, the second limiting surface 413 abuts against the limiting protrusion 11. At this time, the connecting rod 40 cannot continue to rotate, so that the connecting rod 40 can be more stably in the second state, thereby enhancing the structural stability of the antenna assembly 20 in the second state.

[0070] In some embodiments, the arc of the arc surface 411 is 180 degrees.

[0071] As a result, the maximum travel range of the antenna assembly 20 when switching between the first state and the second state is 180 degrees. In this way, it is possible to reduce unnecessary rotation of the antenna assembly 20 while achieving posture switching of the antenna assembly 20 between the first state and the second state.

[0072] In some embodiments, the plate-shaped box body 22 includes a base 221 and a protective cover 222. The base 221 is threadedly connected to the rotating rod 21. The protective cover 222 is covered on the base 221 and defines an installation space for installing the radiator. Thus, the base 221 can be threadedly connected to the rotating rod 21 to enhance the connection stability between the base 221 and the rotating rod 21. The base 221 is threadedly connected to the rotating rod 21, which can easily reduce the difficulty of loading and unloading, thereby reducing the difficulty of maintenance.

[0073] In particular, the radiator is installed between the protective cover 222 and the base 221, so that the protective cover 222 and the base 221 can provide a certain degree of protection for the radiator, thereby preventing the water pressure from damaging the radiator after the underwater submersible enters the water, and ensuring the sealing of the installation environment of the radiator.

[0074] In some embodiments, the protective cover 222 includes a bottom plate 2221 and a side plate 2222, the bottom plate 2221 is arranged opposite to the base 221, the side plate 2222 is arranged around the bottom plate 2221 in the circumferential direction of the bottom plate 2221 and is connected between the bottom plate 2221 and the base 221; wherein the positive projection of the bottom plate 2221 on the base 221 falls within the base 221, and a guide slope 2223 is formed on the side of the side plate 2222 facing away from the installation space.

[0075] It is understandable that after the underwater submersible enters the water, there will be water around the protective cover 222 and the base 221, and a guide slope 2223 is provided on the side of the side plate 2222 facing away from the installation space, so that when water hits the side plate 2222, the guide slope 2223 can be used to guide the water to a certain extent, thereby reducing the risk of damage to the protective cover 222 caused by excessive water pressure. In particular, when the underwater submersible is ascending or descending, the guide slope 2223 can be used to guide the water to a certain extent, thereby reducing the risk of damage to the protective cover 222 caused by excessive water pressure.

[0076] In some embodiments, the rotating rod 21 is connected to the plate-shaped box body 22 by welding, thereby enhancing the connection stability between the two.

[0077] In some embodiments, a plurality of seals are provided at the connection between the connecting rod 40 and the mounting seat 10. The seals may be rubber rings or sealants, etc. This facilitates enhancing the sealing of the connection between the connecting rod 40 and the mounting seat 10 and reducing the risk of water ingress.

[0078] The application also proposes an underwater submersible.

[0079] It is understandable that the underwater submersible of the present application may be an underwater submarine, an underwater robot or other underwater observation device, which is not limited here.

[0080] The underwater submersible according to the embodiment of the present application includes the antenna device 100 for underwater submersible according to any one of the above embodiments. For example, the underwater submersible includes a submersible cabin and the antenna device 100, and the communication module is installed in the submersible cabin and is electrically connected to the radiator through a cable, so as to control the radiator to transmit and / or receive satellite signals through the communication module.

[0081] According to the underwater submersible of the embodiment of the present application, the rotating rod 21 of the antenna device 100 used for the underwater submersible can drive the plate-shaped box body 22 to rotate relative to the mounting seat 10 so that the antenna assembly 20 can switch between the first state and the second state, thereby facilitating the posture adjustment of the antenna assembly 20 to meet communication requirements, thereby reducing the posture adjustment requirements of the underwater submersible when meeting satellite communication requirements. In particular, when the antenna assembly 20 is in the second state, the positive projection of the other end of the rotating rod 21 on the mounting seat 10 falls within the mounting seat 10. In this way, the projection of the antenna device 100 for the underwater submersible in the direction from the rotating rod 21 to the mounting seat 10 is smaller, so as to reduce the difficulty of transportation.
