As an embodiment of the present invention, as shown in fig. 5 and 7, a signal transmitter 63 is disposed on the inner side of the satellite receiver 62, a demodulator 64 is disposed on the inner side of the satellite receiver 62, the satellite receiver 62 is respectively connected with the signal transmitter 63 and the demodulator 64, the tuner 10 is connected with the satellite receiver 62 through a copper transmission line 85, the tuner 10 is fixedly connected on the outer side of the hot end cover 82, the feed plate 11 is fixedly connected on the bottom of the tuner 10, and the filter 9 is fixedly connected on the top of the tuner 10.
When the device is used, firstly, the satellite signals in the sky are reflected and converged into a focus through the parabolic antenna 61, and because the feed plate 11 is arranged at the focusing point of the reflected signals of the parabolic antenna 61, the satellite signals reflected by the parabolic antenna 61 are received by the feed plate 11, the feed plate 11 transmits the received satellite signals to the tuner 10, the satellite signals transmitted to the tuner 10 firstly filter clutter in the satellite signals through the filter 9, the satellite signals after filtering are subjected to frequency reduction and amplification through the tuner 10, the satellite signals after frequency reduction and amplification are transmitted to the inside of the satellite receiver 62 through the copper transmission line 85, the conventional tuner 10 transmits the down-converted and amplified satellite signals to the satellite receiver 62 through the signal transmitter, and the filter 9, the tuner 10 and the satellite receiver 62 generate electromagnetic interference during operation, the electromagnetic interference will cause interference to the satellite signals transmitted by the signal transmitter and will lead to the distortion of the satellite signals transmitted by the signal transmitter, and the copper transmission line 85 is arranged inside the copper pipe shell 81 and the hot end cover 82, and the copper pipe shell 81 is made of copper, which has a strong shielding effect on the electromagnetic interference, so that the satellite signals transmitted to the satellite receiver 62 by the tuner 10 will not be distorted by the electromagnetic interference, and the copper material will not be greatly affected by temperature during signal transmission;
The satellite signals transmitted to the satellite receiver 62 are demodulated and decoded by a demodulator 64, which converts the satellite signals into navigation data usable by navigation software on the device, and the demodulated and decoded navigation data is transmitted to the navigation device via a signal transmitter 63.
As an embodiment of the present invention, as shown in fig. 5 and 6, the tuner 10 is respectively connected to the filter 9 and the feed plate 11 by signals, the feed plate 11 is fixedly installed at a focusing point of a reflecting surface of the parabolic antenna 61 through a copper tube housing 81, the copper tube housing 81, a hot end cover 82 and a cold end cover 84 are communicated, a copper transmission line 85 is penetratingly provided inside the copper tube housing 81, the hot end cover 82 and the cold end cover 84, and the copper transmission line 85 is hermetically provided between the hot end cover 82 and the cold end cover 84, and the hot end cover 82 is respectively in contact with the filter 9, the tuner 10 and the feed plate 11.
During operation, because the satellite signal amplifying device needs to continuously work for a long time, after the satellite signal amplifying device works for a long time, a great amount of heat is generated on the filter 9, the tuner 10 and the feed plate 11, because the satellite signal amplifying device is arranged in a remote area, the remote area is inconvenient for maintenance personnel to constantly remove maintenance, therefore, in order to protect the filter 9, the tuner 10 and the feed plate 11, a thicker protective shell is arranged on the outer sides of the filter 9, the tuner 10 and the feed plate 11, the filter 9, the tuner 10 and the feed plate 11 are prevented from being damaged, the thicker protective shell inevitably reduces the heat dissipation of electronic components inside the filter 9, the tuner 10 and the feed plate 11, at this time, the heat dissipation and cooling are insufficient for supporting the satellite signal amplifying device only through natural air cooling, at this time, because a hot end cover 82 is respectively contacted with the filter 9, the tuner 10 and the feed plate 11, and a cold end cover 84 is also copper, copper is very strong in self-conducting property, the copper pipe 82 can lead the filter 9, the tuner 10 and the feed plate 11 to be provided with a copper pipe, the heat conducting core is more, the heat conducting material inside the filter 81 is carried away from the filter 9, the tuner 10 and the heat conducting core 10 is more inside the shell 81, the liquid is absorbed by the liquid 81 inside the liquid 81, the liquid 81 is absorbed by the liquid 81 inside the shell 81, and the liquid 81 is filled into the inner part of the shell 81, and the liquid 81 is vaporized inside the shell 81, and is air-filled into the inner part of the shell 81, and is cooled by the liquid 81, and is cooled inside the liquid 81, and is cooled by the liquid 81, the cold end cover 84 is relatively cold, so that the vaporized liquid reaching the cold end cover 84 is condensed and changed into liquid, and a large amount of heat is discharged, the discharged heat is transmitted to the parabolic antenna 61 through the cold end cover 84, and the condensed liquid at the cold end cover 84 is absorbed to the hot end cover 82 again under the capillary absorption action of the liquid absorbing core 83, so that the heat generated at the filter 9, the tuner 10 and the feed source disc 11 can be continuously discharged;
Because the area of the parabolic aerial 61 in contact with the air is relatively large, heat transmitted to the parabolic aerial 61 can be rapidly spread on the parabolic aerial 61 and taken away by the air, in the process, because the satellite signal amplifying device is arranged in a remote area, the satellite signal amplifying device is arranged at a higher position for better receiving satellite signals, and the higher position is usually accompanied by larger wind, and the air is relatively moist, so that if the surface of the parabolic aerial 61 is supercooled, water vapor in the air can be accumulated on the surface of the parabolic aerial 61 to form water drops, and the water drops can lead to deflection of signals reflected by the parabolic aerial 61, so that the strength of the parabolic aerial 61 focuses the satellite signals is reduced, and therefore, on one hand, the heat on the parabolic aerial 61 can not enable the temperature of the surface layer of the parabolic aerial 61 to be too low, and on the other hand, even a small amount of water vapor on the parabolic aerial 61 can be rapidly evaporated, so that the strength of the focused satellite signals of the parabolic aerial 61 cannot deflect.
Working principle: when the device works, after the supporting plate 1 is placed at a designated position, the supporting plate 1 is fixed at the designated position after penetrating through the mounting hole by using the bolts, then the device is assembled, and after the assembly is completed, the rotating disc 2 and the adjusting mechanism 5 can automatically adjust the deflection angle and the elevation angle of the parabolic antenna 61 according to the strength and the azimuth of the signal received by the parabolic antenna 61, so that the best signal strength received by the parabolic antenna 61 is ensured;
When the device is used, satellite signals in the sky are reflected and converged into a focus through the parabolic antenna 61, the feed plate 11 is arranged at a focusing point of the reflected signals of the parabolic antenna 61, so that the satellite signals reflected by the parabolic antenna 61 are received by the feed plate 11, the feed plate 11 transmits the received satellite signals to the tuner 10, the satellite signals transmitted to the tuner 10 firstly filter clutter in the satellite signals through the filter 9, the filtered satellite signals are subjected to frequency reduction and amplification through the tuner 10, the satellite signals after frequency reduction and amplification are transmitted to the satellite receiver 62 through the copper transmission line 85, the traditional tuner 10 transmits the satellite signals after frequency reduction and amplification to the satellite receiver 62 through the signal transmitter, electromagnetic interference can be generated by the filter 9, the tuner 10 and the satellite receiver 62 in operation, the satellite signals transmitted by the signal transmitter can be caused to be interfered, the copper transmission line 85 is arranged in the copper transmission line 82, and the copper pipe 81 is not greatly affected by the electromagnetic interference of the copper transmission line 81, and the copper transmission line is not greatly affected by the copper transmission line 81, and the copper transmission line is high in temperature, and the copper transmission line 81 is not affected by the copper transmission line is greatly;
The satellite signals transmitted to the satellite receiver 62 are demodulated and decoded by the demodulator 64, the demodulation and decoding convert the satellite signals into navigation data usable by navigation software on the device, and the demodulated and decoded navigation data are transmitted to the navigation device through the signal transmitter 63;
Because the satellite signal amplifying device needs to work continuously for a long time, a large amount of heat is generated on the filter 9, the tuner 10 and the feed plate 11 after the satellite signal amplifying device works for a long time, because the satellite signal amplifying device is arranged in a remote area, maintenance personnel is inconvenient to maintain frequently in the remote area, in order to protect the filter 9, the tuner 10 and the feed plate 11, thicker protective shells are arranged on the outer sides of the filter 9, the tuner 10 and the feed plate 11 to avoid damage to the filter 9, the tuner 10 and the feed plate 11, the thicker protective shells inevitably reduce heat dissipation of electronic components inside the filter 9, the tuner 10 and the feed plate 11, and at the moment, the heat dissipation and cooling by natural air cooling are insufficient to support the long-time work of the satellite signal amplifying device, and at the moment, the heat end covers 82 are respectively contacted with the filter 9, the tuner 10 and the feed plate 11, the material of the hot end cover 82 and the cold end cover 84 is copper, and the copper has strong heat conduction property, so the hot end cover 82 can quickly guide the heat generated on the filter 9, the tuner 10 and the feed plate 11 to the liquid suction core 83 in the copper pipe shell 81, and can pump away part of the air in the copper pipe shell 81 and inject a small amount of liquid into the copper pipe shell 81, so the air pressure in the copper pipe shell 81 is smaller than the air pressure of the outside, the liquid in the copper pipe shell 81 can be absorbed by the liquid suction core 83, at the moment, the heat led into the liquid suction core 83 by the hot end cover 82 can lead the liquid on the liquid suction core 83 to be vaporized, more heat is taken away after the liquid is vaporized, thereby the heat dissipation on the filter 9, the tuner 10 and the feed plate 11 is completed, and the vaporized liquid can be diffused to the cold end cover 84 in the copper pipe shell 81, the cold end cover 84 is relatively cold, so that the vaporized liquid reaching the cold end cover 84 is condensed and changed into liquid, and a large amount of heat is discharged, the discharged heat is transmitted to the parabolic antenna 61 through the cold end cover 84, and the condensed liquid at the cold end cover 84 is absorbed to the hot end cover 82 again under the capillary absorption action of the liquid absorbing core 83, so that the heat generated at the filter 9, the tuner 10 and the feed source disc 11 can be continuously discharged;
Because the area of the parabolic antenna 61 contacted with the air is relatively large, heat transmitted to the parabolic antenna 61 can be rapidly spread on the parabolic antenna 61 and taken away by the air, in the process, because the satellite signal amplifying device is arranged in a remote area, the satellite signal amplifying device is arranged at a higher position for better receiving satellite signals, and the higher position is usually accompanied by larger wind, and the air is relatively moist, if the surface of the parabolic antenna 61 is supercooled, water vapor in the air can be accumulated on the surface of the parabolic antenna 61 to form water drops, and the water drops can lead to the deflection of signals reflected by the parabolic antenna 61, so that the strength of the parabolic antenna 61 focusing the satellite signals can be reduced, and therefore, on one hand, the heat on the parabolic antenna 61 can not enable the temperature of the surface layer of the parabolic antenna 61 to be too low, and on the other hand, even a small amount of water vapor on the parabolic antenna 61 can be rapidly evaporated, so that the strength of the focused satellite signals of the parabolic antenna 61 cannot deflect;
Because the wind at the higher position is larger, wind blown on the satellite signal amplifying device can blow the wind receiving plate 77 to rotate, and because the structure of the wind receiving plate 77 is arranged, wind in any direction can blow the wind receiving plate 77 to rotate, the wind receiving plate 77 can drive the fan 76 to rotate after rotating, the fan 76 can blow out wind through the wind outlet groove 73 and the surrounding wind outlet pipe 72 after rotating, the wind is equidistantly and circumferentially distributed on the inner side of the wind resistance plate 71 between the surrounding wind outlet pipes 72, therefore, when the wind is blown out of the surrounding wind pipe 72, a gathered cyclone is formed in the parabolic antenna 61, after the cyclone reaches the center of the parabolic antenna 61, the cyclone can be outwards spread, namely, impurities such as fallen leaves in the parabolic antenna 61 can be cleaned up, and outwards spread at the flaring of the parabolic antenna 61 can also be formed, and simultaneously can be matched to blow down or take away the water vapor on the parabolic antenna 61, if the wind is blown on the back of the parabolic antenna 61, the wind is spread out through the surrounding wind outlet groove 73, the convex surface of the parabolic antenna 61, the wind is spread out of the parabolic antenna 61 at the moment, the wind is blown out of the parabolic antenna 61, the cyclone is more stable, and the wind is blown out of the parabolic antenna 61, and the parabolic antenna is more stable, and the wind is blown out of the parabolic antenna 61, and the parabolic antenna is blown out of the parabolic antenna is more than the parabolic antenna 61, and the parabolic antenna is blown out, and the parabolic antenna is more than the parabolic antenna 61, and the noise is blown out, and the noise is more stable, and the noise is blown out.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
