Description

[0003] Currently, the ship signal receiving devices on the market mainly adopt a fixed installation method. Once the installation position is determined, it is difficult to adjust it again. This makes it impossible for large ships to flexibly change the signal receiving direction during different navigation phases or when encountering different sea conditions, thus affecting the timeliness and accuracy of information transmission.

[0025] The present invention also provides a method for using a ship signal receiving device, comprising the following steps:

[0026] Step 1: When installing the hemispherical antenna, place the satellite receiver in the center on the top surface of the four L-shaped connecting plates. Under the driving action of the second electric telescopic cylinder, the cross top plate is driven to rise. Under the hinged action of the hinged connecting plate, the U-shaped ear seat, and the U-shaped notch, the L-shaped slide plate and the U-shaped slide block are driven to slide inward along the I-shaped slide rail, and the limit pin shaft is driven to be inserted into the corresponding limit pin hole, thereby forming a fixed installation for the satellite receiver and the hemispherical antenna;

[0027] Step 2: When the hemispherical antenna is raised and adjusted, the lifting plate is raised under the driving action of the first electric telescopic cylinder. Under the hinged action of the hinged connecting rod and the first swing arm and the second swing arm, a multi-link telescopic frame is formed, which drives the fixed plate, the cross bottom plate, the cross top plate, the satellite receiver, and the hemispherical antenna to further rise, and simultaneously drives the fixed slide rod to slide upward along the fixed slide hole, so that the satellite receiver and the hemispherical antenna are raised to the appropriate position;

[0028] Step 3: When the hemispherical antenna swings left and right, under the driving action of the first motor, the motor shaft of the first motor drives the first pin shaft and the first semicircular bracket to rotate along the first ear seat, and drives the second trapezoidal slider to slide along the limiting slide groove, and simultaneously drives the fixed pin shaft to slide along the second flat pin hole, thereby driving the cross bottom plate, the cross top plate, the satellite receiver, and the hemispherical antenna to swing left and right;

[0029] Step 4. When the hemispherical antenna swings back and forth, under the driving action of the second motor, the motor shaft of the second motor drives the second pin shaft and the second semicircular bracket to rotate along the second ear seat, and drives the second trapezoidal slider and the spherical block to slide along the first trapezoidal slider, and simultaneously drives the fixed pin shaft to slide along the first flat pin hole, thereby driving the cross bottom plate, the cross top plate, the satellite receiver, and the hemispherical antenna to swing back and forth for adjustment.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention simplifies the installation process when installing satellite receivers and hemispherical antennas. Installers only need to place the equipment in a suitable location and then fix it with a clamping mechanism, without the need for complex welding or drilling operations.

[0032] Satellite receivers and hemispherical antennas of different models and sizes can be fixed with a suitable clamping mechanism. There are many sophisticated electronic components inside the satellite receiver and hemispherical antenna. A stable installation environment can prevent these components from loosening and being damaged due to vibration.

[0033] 2. In the present invention, different satellites are located at different orbital heights and angles. The lifting antenna can be easily adjusted to point to satellites in different orbits. By raising the antenna to an appropriate height, signals from satellites in different orbits can be flexibly switched to be received according to actual needs, thereby improving the adaptability of the device to different satellite systems. When the satellite receiver and hemispherical antenna are raised to an appropriate height, a certain space will be formed below them, making it easier for maintenance personnel to operate.

[0034] 3. In the present invention, after the satellite receiver and hemispherical antenna are installed on a ship, they may shake or tilt during movement or operation. The multi-directional swing adjustment of the limit mechanism can compensate for these changes, so that the antenna always remains in a suitable signal receiving position. The satellite antenna installed on the ship can continuously adjust the antenna position through the limit mechanism as the ship shakes in the waves, thereby ensuring stable signal reception during the ship's navigation.

The lifting plate 12 is connected to the U-shaped plate 11 and the fixed plate 2 through a hinge mechanism;

[0047] A pair of first ear seats 21 are fixed on the front and rear sides of the top surface of the fixing plate 2. A first semicircular bracket 22 with a downward opening is hingedly provided between the pair of first ear seats 21, and a first flat pin hole is provided on the first semicircular bracket 22.

A second semicircular bracket 24 with an opening facing downward is hingedly provided between the pair of second ear seats 23, and a second flat pin hole is provided on the second semicircular bracket 24.

[0049] The second semicircular bracket 24 is located in the opening of the first semicircular bracket 22, and a fixed pin shaft 34 is slidably inserted into the overlap between the first flat pin hole and the second flat pin hole. The bottom end of the fixed pin shaft 34 is connected to the fixed plate 2 through a limiting mechanism.

[0050] A cross bottom plate 35 is fixed to the top of the fixed pin 34. A second electric telescopic cylinder 36 with its telescopic end facing upward is installed in the middle of the top surface of the cross bottom plate 35. The end of the telescopic rod of the second electric telescopic cylinder 36 is fixed to the cross top plate 4. Under the driving action of the second electric telescopic cylinder 36, the cross top plate 4 is driven to rise.

[0051] A suspended satellite receiver 46 is provided above the cross top plate 4. The cross top plate 4 is connected to the satellite receiver 46 via a clamping mechanism, and a hemispherical antenna 47 with an upward opening is fixed in the middle of the top surface of the satellite receiver 46.

[0052] It can flexibly adjust the direction and angle of signal reception according to different navigation environments and needs, adapt to the diverse signal needs in a changing navigation environment, and adaptively adjust the direction and range of signal reception in different navigation stages and sea conditions to improve navigation efficiency and safety, which are important needs.

[0053] Example 2: Based on Example 1, this example also includes:

[0054] In the specific implementation process, Figure 2 and Figure 3As shown, the hinge mechanism includes a fixed connecting plate 14, a first swing arm 15, and a second swing arm 16. The front and rear sides of the lifting plate 12 are hingedly provided with two pairs of hinged connecting rods 13 distributed in an "X" shape. A pair of fixed connecting plates 14 are fixed on the front and rear sides of the bottom of the fixed plate 2.

[0055] Each fixed connecting plate 14 is hingedly provided with a first swing arm 15 at each corner, and the bottom end of each first swing arm 15 is movably hinged to the top end of the adjacent hinged link 13. Two pairs of second swing arms 16 are hingedly provided on the front and rear side surfaces of the U-shaped plate 11, and the top end of each second swing arm 16 is movably hinged to the bottom end of the adjacent hinged link 13. Under the hinged action of the hinged link 13 and the first and second swing arms 15 and 16, a multi-link telescopic frame is formed, which drives the fixed plate 2, cross bottom plate 35, cross top plate 4, satellite receiver 46, and hemispherical antenna 47 to further rise.

[0056] A first electric telescopic cylinder 17 with its telescopic end facing upward is installed in the middle of the top wall of the U-shaped plate 11. The end of the telescopic rod of the first electric telescopic cylinder 17 slides through the U-shaped plate 11 and is fixed to the middle of the lifting plate 12. Under the driving action of the first electric telescopic cylinder 17, the lifting plate 12 is driven to rise.

[0057] The four corners of the lifting plate 12 are provided with fixed sliding holes. A fixed sliding rod 18 is inserted into each fixed sliding hole and slides through it. The top end of each fixed sliding rod 18 is fixedly connected to the bottom surface of the fixed plate 2. The fixed sliding rod 18 slides upward along the fixed sliding hole, so that the satellite receiver 46 and the hemispherical antenna 47 are raised to the appropriate position.

[0058] The satellite receiver 46 and the hemispherical antenna 47 are raised to a suitable position by the double lifting effect of the articulated mechanism, thereby avoiding being blocked by obstacles such as ships. The reception angle of the satellite signal is optimized, the signal strength and quality are significantly improved, and the signal blind spots are effectively reduced.

[0059] When the satellite receiver 46 and the hemispherical antenna 47 are in a higher position, they can reduce contact with these interference sources, making the signal received by the antenna purer. The height of the satellite receiver 46 and the hemispherical antenna 47 can be flexibly adjusted by lifting the hinge mechanism to adapt to different changes.

[0060] Example 3: Based on Example 2, this example also includes:

[0061] In the specific implementation process, Figure 4 and Figure 5As shown, the limiting mechanism includes a second trapezoidal slider 33 and a first trapezoidal slider 32. A spherical block 3 is provided in the opening of the second semicircular bracket 24 and is suspended. Four through-distributed limiting grooves are provided on the outer surface of the spherical block 3. The bottom end of the fixed pin 34 is fixed with a second trapezoidal slider 33. The second trapezoidal slider 33 is engaged in the adjacent limiting grooves in a sliding manner. The second trapezoidal slider 33 slides along the limiting grooves, synchronously driving the fixed pin 34 to slide along the second flat pin hole, thereby driving the cross bottom plate 35, the cross top plate 4, the satellite receiver 46, and the hemispherical antenna 47 to swing left and right.

[0062] A positioning seat 31 is fixedly provided in the middle of the top surface of the fixing plate 2. A first trapezoidal slider 32 is fixedly provided in the middle of the top surface of the positioning seat 31. The first trapezoidal slider 32 slides back and forth and engages in the adjacent limiting slide groove. The second trapezoidal slider 33 and the spherical block 3 slide along the first trapezoidal slider 32, synchronously driving the fixing pin 34 to slide along the first flat pin hole, thereby driving the cross bottom plate 35, the cross top plate 4, the satellite receiver 46, and the hemispherical antenna 47 to swing back and forth for adjustment.

[0063] A pair of first pins are fixedly provided at both ends of the first semicircular bracket 22, and the outer end of each first pin is rotatably inserted into the corresponding first ear seat 21; a first side plate 25 is fixedly provided on the front side of the fixed plate 2, and a first through hole is opened on the top of the first side plate 25. A first motor 26 is installed inside the first through hole, and the motor shaft end of the first motor 26 is fixedly connected to the first pin on the adjacent side. The motor shaft of the first motor 26 drives the first pin and the first semicircular bracket 22 to rotate along the first ear seat 21;

[0064] A pair of second pins are fixedly provided at both ends of the second semicircular bracket 24, and the outer end of each second pin is rotatably inserted into the corresponding second ear seat 23; a second side plate 27 is fixedly provided on the right side of the fixed plate 2, and a second through hole is opened on the top of the second side plate 27. A second motor 28 is installed inside the second through hole, and the motor shaft end of the second motor 28 is fixedly connected to the second pin on the adjacent side. The motor shaft of the second motor 28 drives the second pin and the second semicircular bracket 24 to rotate along the second ear seat 23;

[0065] The reception of satellite signals requires extremely high antenna pointing accuracy. By using the limit mechanism to adjust the satellite receiver 46 and the hemispherical antenna 47 in multiple directions, the antenna pointing can be finely adjusted to enable it to accurately align with the satellite.

[0066] Through this multi-directional adjustment, the azimuth and elevation angles of the antenna can be accurately adjusted to the strongest receiving angle of the target satellite signal, thereby obtaining the clearest and most stable satellite signal. When it is necessary to switch to receive signals from different satellites, the multi-directional swing adjustment function of the limit mechanism is particularly important.

[0067] Example 4: Based on Example 3, this example also includes:

[0068] In the specific implementation process, Figure 6 and Figure 7 As shown, four evenly distributed I-shaped slide rails 41 are fixed on the top surface of the cross top plate 4. A U-shaped slider 42 is slidably engaged in the middle of each I-shaped slide rail 41. An L-shaped slide plate 43 with a downward opening is fixed on the top surface of each U-shaped slider 42.

[0069] The clamping mechanism includes an L-shaped connecting plate 44 and a limiting pin 45. A pair of limiting pin holes are opened in the middle of the four sides of the satellite receiver 46. An L-shaped connecting plate 44 with an upward opening is fixed on the top surface of each L-shaped slide plate 43. A pair of limiting pins 45 are fixed on the top of the inner side of each L-shaped connecting plate 44. The outer end of each limiting pin 45 is slidably inserted into the corresponding limiting pin hole. The limiting pin 45 is inserted into the corresponding limiting pin hole to form a fixed installation for the satellite receiver 46 and the hemispherical antenna 47.

[0070] U-shaped ears 37 are fixed at the four corners of the top surface of the cross base 35. A U-shaped notch is opened at the bottom of each L-shaped slide 43. A hinged connecting plate 38 is hingedly provided inside each U-shaped notch. The bottom end of each hinged connecting plate 38 is hingedly engaged in the opening of the U-shaped ear 37 on the adjacent side. Under the hinged action of the hinged connecting plate 38, the U-shaped ear 37 and the U-shaped notch, the L-shaped slide 43 and the U-shaped slider 42 are driven to slide inward along the I-shaped slide rail 41.

[0071] The satellite receiver 46 and the hemispherical antenna 47 need to be precisely aligned with the satellite signal source. Factors such as wind and vibration in the external environment may interfere with their normal operation. By using the clamping mechanism, they can be firmly fixed; in a strong wind environment, the clamping mechanism can prevent the satellite receiver 46 and the hemispherical antenna 47 from shaking. This stability helps to maintain the continuity and accuracy of signal reception and reduce signal interruption or quality degradation.

[0072] Specifically, the working principle and operation method of the present invention are as follows:

[0073] Step 1: When installing the hemispherical antenna 47, the satellite receiver 46 is placed centrally on the top surfaces of the four L-shaped connecting plates 44. Under the driving action of the second electric telescopic cylinder 36, the cross top plate 4 is driven to rise. Under the hinged action of the hinged connecting plate 38, the U-shaped ear seat 37, and the U-shaped notch, the L-shaped slide plate 43 and the U-shaped slide block 42 are driven to slide inward along the I-shaped slide rail 41, and the limit pin shaft 45 is driven to be inserted into the corresponding limit pin hole, thereby forming a fixed installation for the satellite receiver 46 and the hemispherical antenna 47;

[0074] In step 2, when the hemispherical antenna 47 is raised and adjusted, the lifting plate 12 is raised under the driving action of the first electric telescopic cylinder 17. Under the hinged action of the articulated link 13 and the first swing arm 15 and the second swing arm 16, a multi-link telescopic frame is formed, which drives the fixed plate 2, the cross bottom plate 35, the cross top plate 4, the satellite receiver 46, and the hemispherical antenna 47 to further rise, and simultaneously drives the fixed slide rod 18 to slide upward along the fixed slide hole, so that the satellite receiver 46 and the hemispherical antenna 47 are raised to the appropriate position;

[0075] Step 3: When the hemispherical antenna 47 swings left and right, under the driving action of the first motor 26, the motor shaft of the first motor 26 drives the first pin shaft and the first semicircular bracket 22 to rotate along the first ear seat 21, and drives the second trapezoidal slider 33 to slide along the limiting slide groove, and simultaneously drives the fixed pin shaft 34 to slide along the second flat pin hole, thereby driving the cross bottom plate 35, the cross top plate 4, the satellite receiver 46, and the hemispherical antenna 47 to swing left and right;

[0076] Step 4. When the hemispherical antenna 47 swings back and forth, under the driving action of the second motor 28, the motor shaft of the second motor 28 drives the second pin shaft and the second semicircular bracket 24 to rotate along the second ear seat 23, and drives the second trapezoidal slider 33 and the spherical block 3 to slide along the first trapezoidal slider 32, and synchronously drives the fixed pin shaft 34 to slide along the first flat pin hole, thereby driving the cross bottom plate 35, the cross top plate 4, the satellite receiver 46, and the hemispherical antenna 47 to swing back and forth for adjustment.
