Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a multi-beam antenna and a ship. Background Technology

[0002] A multi-beam antenna is an antenna that can generate multiple sharp beams. These sharp beams (called meta-beams) can be combined into one or more shaped beams to cover a specific airspace. This type of antenna is most widely used in marine vessels.

[0003] However, existing multi-beam antennas still present certain problems in use. For example, the easily adjustable receiving antenna disclosed in CN211907660U can be problematic on smaller vessels such as yachts and speedboats, where the antenna sways from side to side with the waves. The satellite antenna on the vessel also moves accordingly. Since the signal receiving surface of a typical satellite antenna is relatively fixed, even if the signal receiving angle has a certain range, when it exceeds this range, the antenna will adjust its receiving surface through its own mechanical structure. Under certain wind speeds, the swaying frequency is high, resulting in a large number of adjustments. Although the adjustment range is not large, it still has a certain impact on the service life of its mechanical parts. Summary of the Invention

[0004] To address the problems in the prior art, this application proposes a multi-beam antenna and a ship, which can ensure the stability of the signal receiving surface of the multi-beam antenna as much as possible when the ship is swaying.

[0005] This invention provides a multi-beam antenna, comprising a support for mounting on a ship's body and an antenna body mounted on the support via a tuner. The tuner includes a carrier frame, a movable mechanism, and two connecting arms. The carrier frame is mounted on the support, and the movable mechanism is movably mounted on the carrier frame. The carrier frame is equipped with a hinged arm, and the antenna body is hinged to the hinged arm. The two connecting arms are symmetrically arranged on both sides of the hinged arm, with the first end of each connecting arm hinged to the antenna body and the second end of each connecting arm connected to the carrier frame via a connecting strap. The two connecting straps are symmetrically arranged on the movement paths on both sides of the movable mechanism and can be abutted by the movable mechanism.

[0006] The movable mechanism can move in the same direction as the ship body sways, and at the same time abut against the corresponding connecting belt. The connecting belt pulls the corresponding connecting arm to move, so that the antenna body rotates around the position where it is hinged to the hinge arm.

[0007] As a further improvement to the above technical solution:

[0008] The aforementioned multi-beam antenna, further comprising:

[0009] A sliding assembly, movable relative to the support frame, wherein the sliding assembly is provided with an abutment member; and

[0010] A drive assembly includes a drive cavity and a reset member. The drive cavity is filled with liquid, which changes the center of gravity of the drive cavity as the ship body sways, thereby driving the sliding assembly to move relative to the support frame so that the abutment member abuts against the corresponding connecting strip. The reset member is used to drive the sliding assembly to reset.

[0011] Furthermore, in the aforementioned multi-beam antenna, the support frame is provided with a sliding shaft, the sliding assembly includes a support rod and a sleeve mounted on the support rod, the sleeve is sleeved on the sliding shaft, and the reset element is a reset spring, with the reset spring sleeved on the sliding shaft on both sides of the sleeve.

[0012] Furthermore, in the aforementioned multi-beam antenna, the sidewall of the sliding shaft is provided with a guide rail extending along its axial direction, and the inner sidewall of the sleeve is provided with a guide rail groove that cooperates with the guide rail, allowing the sleeve to slide along the guide rail.

[0013] Furthermore, in the aforementioned multi-beam antenna, the thickness of the guide rail gradually increases from the middle of the guide rail towards both sides.

[0014] The bottom of the drive cavity is provided with a liquid-blocking block, which is located in the middle of the bottom and its thickness gradually decreases towards both sides.

[0015] Furthermore, in the aforementioned multi-beam antenna, the support frame is provided with a pair of guide rods, through which the connecting strap passes, and the guide rods are used to adjust the traction direction of the connecting strap.

[0016] Furthermore, the multi-beam antenna described above also includes an outer cover, which is detachably mounted on the support and covers the outside of the antenna body and the tuner.

[0017] Furthermore, the aforementioned multi-beam antenna is further provided with multiple reinforcing rods on the support, which are used to assist the support in being installed on the ship's body.

[0018] In another aspect, the present invention provides a ship comprising a ship body and a multi-beam antenna as described above, wherein the support is mounted on the ship body.

[0019] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of this invention can be achieved.

[0020] The multi-beam antenna and ship provided by this invention have at least the following advantages compared with the prior art: When in use, the support of the multi-beam antenna is installed on the ship body. When the ship is sailing on the water, it will sway due to the action of water waves or wind. The movable mechanism can move in the same direction as the ship body sways and at the same time abut against the corresponding connecting belt. The connecting belt pulls the corresponding connecting arm to move, so that the antenna body rotates around the position of the hinge arm, thereby ensuring the stability of the signal receiving surface of the antenna body as much as possible and the angle deviation from the optimal receiving surface is not too large.

[0037] The invention will now be further described with reference to the accompanying drawings.

[0038] This invention provides a multi-beam antenna 100 to ensure the stability of the signal receiving surface of the multi-beam antenna 100 as much as possible when the ship is swaying.

[0039] like Figures 1 to 5 As shown, the multi-beam antenna 100 provided in this embodiment of the invention includes a support 110 for mounting on the ship body and an antenna body 140 mounted on the support 110 via a tuner 120. The tuner 120 includes a carrier frame 121, a movable mechanism 122, and two connecting arms 123. The carrier frame 121 is mounted on the support 110, and the movable mechanism 122 is movably mounted on the carrier frame 121. The carrier frame 121 is equipped with a hinge arm 124, and the antenna body 140 is hinged to the hinge arm 124. The two connecting arms 123 are symmetrically arranged on both sides of the hinge arm 124, and the first end of the connecting arm 123 is hinged to the antenna body 140. The second end of the connecting arm 123 is connected to the carrier frame 121 via a connecting strap 125. The two connecting straps 125 are symmetrically arranged on the moving paths on both sides of the movable mechanism 122 and can be abutted by the movable mechanism 122 respectively.

[0040] The movable mechanism 122 can move in the same direction as the ship body sways, and at the same time abut against the corresponding connecting belt 125. The connecting belt 125 pulls the corresponding connecting arm 123 to move, so that the antenna body 140 rotates around the position where it is hinged to the hinge arm 124.

[0041] In use, the support 110 of the multi-beam antenna 100 provided in this embodiment of the invention is installed on the ship body. When the ship is sailing on the water, it will sway due to the action of water waves or wind. The movable mechanism 122 can move in the same direction as the ship body sways and at the same time abut against the corresponding connecting belt 125. The connecting belt 125 pulls the corresponding connecting arm 123 to move, so that the antenna body 140 rotates around the position where it is hinged to the hinge arm 124, so as to ensure that the signal receiving surface of the antenna body 140 is as stable as possible and the angle deviation from the optimal receiving surface is not too large.

[0042] The multi-beam antenna 100 provided in this embodiment of the invention is described in detail in the attached document. Figure 3 and Figure 5 The moving mechanism 122 includes a sliding component and a driving component. The sliding component is movable relative to the support frame 121 and is provided with an abutment 126. The driving component includes a driving cavity 127 and a reset component 128. The driving cavity 127 is filled with liquid. The liquid changes the center of gravity of the driving cavity 127 as the ship body sways, thereby driving the sliding component to move relative to the support frame 121 so that the abutment 126 abuts against the corresponding connecting belt 125. The reset component 128 is used to drive the sliding component to reset.

[0043] When a small vessel sways with the waves, the entire support frame 121 will also sway with the vessel. At this time, the liquid inside the drive chamber 127 will flow to one side of the drive chamber 127 due to gravity, causing the entire moving mechanism 122 to lose balance and slide in the direction of the vessel's sway, thereby achieving the purpose of moving the sliding component with the direction of the vessel's sway.

[0044] Two connecting straps 125 are symmetrically arranged on the moving paths on both sides of the movable mechanism 122 and can be abutted by the movable mechanism 122 respectively. The sliding component moves with the swing direction of the ship body, and the abutting part 126 abuts against the corresponding connecting strap 125. The connecting strap 125 pulls the corresponding connecting arm 123 to move, so that the connecting arm 123 is pulled and stretched in the opposite direction of the swing direction of the ship body, so as to ensure that the signal receiving surface of the antenna body 140 is stable as much as possible and the angle deviation from the optimal receiving surface is not too large.

[0045] In this embodiment, the antenna body 140 is hinged to the end of the hinge arm 124 at the middle of its rear side, allowing the antenna body 140 to swing in a circle around this hinge point. The antenna body 140 is made of an ultra-thin material and is lightweight. The main functional components are installed inside the support 110. The antenna body 140 only serves as a signal receiver. When the drive assembly reaches its maximum extension distance, the maximum rotation angle of the antenna body 140 is 10°.

[0046] The abutment 126 is a rectangular frame with a hollowed-out center. Its hollowed-out surface is parallel to the direction of movement of the sliding component relative to the support frame 121. Two connecting straps 125 pass through one side of the abutment 126 to the other side and are connected to the support frame 121.

[0047] The multi-beam antenna 100 provided in this embodiment of the invention is described in detail in the attached document. Figure 3 and Figure 4The support frame 121 is provided with a sliding shaft 129. The sliding assembly includes a support rod 130 and a sleeve 131 installed on the support rod 130. The sleeve 131 is sleeved on the sliding shaft 129. The reset member 128 is a reset spring. Reset springs are sleeved on the sliding shaft 129 on both sides of the sleeve 131.

[0048] In this embodiment, the support frame 121 is provided with two parallel sliding shafts 129, and the support rod 130 is provided with two sleeves 131. The two sleeves 131 are respectively sleeved on the two sliding shafts 129, and a return spring is sleeved on the sliding shafts 129 on both sides of the sleeve 131. When a small ship rocks with the waves, the entire support frame 121 will also rock with the ship's body. At this time, the liquid inside the drive cavity 127 will flow to one side of the drive cavity 127 under the action of gravity, causing the entire moving mechanism 122 to lose balance. The sleeve 131 overcomes the action of the return spring and slides along the sliding shafts 129 in the direction of the ship's body rocking, thereby achieving the purpose of moving the sliding component with the direction of the ship's body rocking. When the rocking amplitude of the ship's body decreases, the sleeve 131 is reset by the action of the return spring.

[0049] The side wall of the sliding shaft 129 is provided with a guide rail 132 extending along its axial direction. The inner side wall of the sleeve 131 is provided with a guide rail groove that mates with the guide rail 132. The sleeve 131 can slide along the guide rail 132, preventing the sleeve 131 from moving in the extended direction. The thickness of the guide rail 132 gradually increases from the middle of the guide rail 132 to both sides. A liquid-blocking block 133 is provided at the bottom of the drive cavity 127, and the liquid-blocking block 133 is located in the middle of the bottom and its thickness gradually decreases towards both sides. The liquid-blocking block 133 divides the liquid in the drive cavity 127 into two streams when it is in a horizontal state. When the fluctuation is small, the liquid flowing to the other side is not enough to make the entire moving mechanism 122 unbalanced, so as not to cause the antenna body 140 to rotate due to the slight rotation of the ship.

[0050] The reset spring also acts as a buffer for the slide and works in conjunction with the liquid baffle 133 to prevent the slide from moving due to small swaying of the ship until the swaying amplitude of the ship is sufficient to overcome the spring force before the antenna body 140 can be angled.

[0051] The multi-beam antenna 100 provided in this embodiment of the invention further includes a support frame 121 with guide rod pairs 134. A connecting strap 125 passes through the guide rod pairs 134, and the guide rod pairs 134 are used to adjust the traction direction of the connecting strap 125. One end of the connecting strap 125 is connected to the end of the connecting arm 123, and the other end passes through the guide rod pairs 134 and through the cavity of the abutment member 126 to connect with the support frame 121. Multiple guide rod pairs 134 are provided and are respectively vertically installed on the support frame 121. One side of the traction strap is attached to the guide rod pairs 134 and the bending path is changed by the arrangement of the guide rod pairs 134. Two sets of guide rod pairs 134 are provided on the support frame 121 near the movable mechanism 122, and the two sets of guide rod pairs 134 are symmetrically distributed in the middle of the support frame 121.

[0052] The multi-beam antenna 100 provided in this embodiment of the invention further includes an outer cover 150, which is detachably mounted on the support 110. The outer cover 150 covers the outside of the antenna body 140 and the tuner 120 to prevent the antenna body 140 from being interfered with by wind. The support 110 is also provided with multiple reinforcing rods 160, which are used to assist the support 110 in being mounted on the ship's hull.

[0053] This invention also proposes a ship, which includes a ship body and a multi-beam antenna 100 as provided in the above embodiments, with a support 110 mounted on the ship body. The specific structure of the multi-beam antenna 100 is as described in the above embodiments.
