Specific embodiment

The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is not It is limited to this.

China in future has 2 for the high pass satellite of online, No. 16 satellites of culminant star and 2019 respectively emitted at present Year, their locating orbital positions were respectively 110.5 degree, 115.5 degree of east longitude by No. 18 satellites of culminant star of transmitting；China uses at present Also there are 2, respectively culminant star 9 and culminant star 9A in the direct broadcast satellite for TV of listening to the radio programme, see, their locating orbital positions are respectively 92.2 degree of east longitude, 101.4 ° of east longitude.

4 satellite position maximums described above differ less than 25 degree, can be by inventing one kind in a face satellite reception day The special fixture that 2-4 LNB can be installed on line simultaneously comes while locking 2-4 satellite." direct broadcast satellite+high throughput satellite " mode Seeking star, with traditional " direct broadcast satellite " mode to seek astrology same, can be realized pair as long as searching out and being described above in 4 satellites any 1 The semaphore lock of another 3 satellites.Concrete scheme is as follows:

A kind of list satellite antenna locks the device of more satellite-signals simultaneously, comprising:

One LNB fixture is installed on a face satellite earth antenna；

Two or more LNB is installed, the relative distance between LNB described in two or more can on the one LNB fixture It adjusts；

LNB described in two or more realizes the locking to two satellite-signals by the adjusting of relative distance, and the LNB is logical It crosses cable and received satellite-signal is transmitted further to satellite receiver.

A kind of list satellite antenna locks the device of more satellite-signals simultaneously, comprising:

One is mounted on the LNB fixture on a face satellite earth antenna；

For installing two or more LNB on the LNB fixture, the LNB fixture be can be realized described in two or more The adjusting of relative distance between LNB, LNB described in two or more are realized by the adjusting of relative distance to two satellite-signals Locking, received satellite-signal is transmitted further to satellite receiver by cable by the LNB.

Two satellites used in the present embodiment is culminant star 9 and culminant star 9A, No. 9 satellites of culminant star and culminant star 9A satellite Position differs less than 10 degree, and it is dedicated can to install simultaneously two LNB on a face satellite earth antenna by utility model one kind Fixture comes while locking 2 satellites.Direct satellite direct broadcast system Integrated Receive Decoder installation method for searching star of new generation and conventional satellite It is same that live broadcast system Integrated Receive Decoder seeks astrology, as long as searching out in culminant star 9 or culminant star 9A, any one satellite can be real Now to the semaphore lock of another satellite.

There are two types of fixtures, a kind of to use one satellite of main receipts, receiving other satellites partially, for receiving 2 satellites, fixture figure See Fig. 1.The corresponding LNB fixing clamp of the other satellites received partially slidably, to adjust it according to satellite earth antenna size The distance of its LNB；Another kind using all satellites are received partially, and for receiving 2 satellites, fixture figure is shown in Fig. 2.The satellite pair received partially The LNB stationary fixture answered slidably, to adjust the distance of each LNB according to satellite earth antenna size.Because of satellite reception Antenna pot face size is had any different, and causes multiple relative positions LNB variant, press receive culminant star 18, culminant star 16, culminant star 9A, No. 9 satellite sequences of culminant star arrange, and by theoretical calculation, relative position spacing is between 2CM-25CM between each LNB, and occurrence is by defending Star receiving antenna size determines.

The fixture is made of multiple (being determined by received number of satellites) fixing clamps, bracket, screw assembly.Wherein fixing clamp For carrying out installation fixation to multiple (being determined by received number of satellites) LNB, fixing clamp is by upper fixing clamp, lower fixing clamp group At；Bracket is for lifting fixing clamp；Installation of the screw assembly between fixing clamp and bracket, bracket and satellite earth antenna is solid It is fixed.Both the above clamp structure is described further below in conjunction with attached drawing:
