First Embodiment
<Basic Configuration Example of Antenna Device>
FIG. 1 is a perspective view showing an example of an antenna apparatus including the antenna support apparatus of the first embodiment. FIG. 2 is a side view showing an example of an antenna apparatus including the antenna support apparatus of the first embodiment. FIG. 3 is a rear view showing an example of an antenna apparatus including the antenna support apparatus of the first embodiment. In each drawing, an xyz three-dimensional orthogonal coordinate system is defined. Hereinafter, the positional relationship between the components of the antenna device will be described on the premise of the state of the basic posture shown in FIGS. 1 to 3.

  The antenna device 1 includes an antenna main body 3 including an antenna reflection plate 31, an antenna support device 5, and a cooling device 7.

  The cooling device 7 is a device that is operated by the supplied electric power, cools the input (inflow) warm air, and discharges the cold air. For example, the cooling device 7 is a device that includes a compressor and releases cold air by using the heat of vaporization of the refrigerant liquefied by the compressor. Here, the cooling device 7 includes a cooling device (first cooling device) 71 and a cooling device 72 (second cooling device).

  The antenna support device 5 has a support 51 and a device-containing casing 52. The support 51 rotatably supports the device-containing housing 52 around each of the “first azimuth axis” and the “elevation axis”.

  The device inclusion housing 52 has an internal space SP 52 in which an antenna communication device (not shown) of the antenna main body 3 is disposed, that is, an internal space SP 52 containing an antenna communication device (not shown). In addition, the device inclusion housing 52 is disposed on the back surface side (−x side in FIG. 1) of the antenna reflection plate 31 to fix (support) the antenna reflection plate 31. Therefore, the support 51 rotatably supports the antenna reflection plate 31 around the “first azimuth axis” and the “elevation axis” via the device inclusion housing 52. Here, the “first azimuth axis” and the “elevation axis” are rotation axes orthogonal to each other. The orthogonal relationship between the first azimuthal axis and the elevational axis also includes the fact that they are actually orthogonal and that the first azimuthal axis and the elevational axis are in the position of twist.

  The support 51 includes a support base (mount) 53, a yoke 54, a shaft (first shaft) 55, a shaft holding box 56, a shaft (third shaft) 57, and a pair of arms 58 and 59. doing.

  The support base 53 has a shaft (second axis) 53A. The central axis of the shaft 53A corresponds to the first azimuth axis described above. A yoke 54 is disposed (mounted) on the upper surface of the shaft 53A. Therefore, the yoke 54 can rotate around the first azimuth axis as the shaft 53A rotates.

  The yoke 54 has a support base 54A, and a pair of wall portions (support pieces) 54B and 54C which rise upward (in the + z direction) from both ends of the support base 54A. The support base 54A is disposed on the upper surface of the shaft 53A. The pair of wall portions 54B and 54C rotatably supports the shaft 55 between the wall portion 54B and the wall portion 54C. Specifically, the shaft 55 has a partial shaft 55A and a partial shaft 55B. The wall 54B rotatably supports one end of the partial shaft 55A, and the wall 54C rotatably supports one end of the partial shaft 55B.

  The shaft holding box 56 is connected to the other end of the partial shaft 55A opposite to the one end held by the wall 54B, and the partial shaft 55B opposite to the one end held by the wall 54C. It is connected with the other end of. That is, in the shaft holding box 56, the partial shafts 55A and 55B are connected such that the partial shafts 55A and 55B extend in opposite directions from the shaft holding box 56. As a result, the shaft holding box 56 is supported by the walls 54B and 54C via the shaft 55 in a floating state between the wall 54B and the wall 54C. Here, the central axis of the shaft 55 corresponds to the elevation axis described above. Therefore, as the shaft 55 rotates, the shaft holding box 56 can rotate around the elevation axis.

  The shaft holding box 56 supports the shaft 57 such that the shaft 57 is orthogonal to the shaft 55. Specifically, the shaft 57 has a partial shaft 57A and a partial shaft 57B. In the shaft holding box 56, one end of the partial shaft 57A and one end of the partial shaft 57B are connected such that the partial shaft 57A and the partial shaft 57B extend in opposite directions from each other.

  The pair of arms 58, 59 sandwich the shaft 57 between the arm 58 and the arm 59, and is rotatably supported with respect to the shaft 57. Specifically, arm 58 rotatably holds the other end of partial shaft 57A opposite to one end connected to shaft holding box 56, and arm 59 is connected to shaft holding box 56. The other end of the partial shaft 57B opposite to the one end is rotatably held. Here, the central axis of the shaft 57 corresponds to the “second azimuth axis”. Therefore, by rotating the arms 58 and 59 with respect to the shaft 57, the arms 58 and 59 can rotate around the second azimuth axis.

  Further, the pair of arms 58 and 59 are connected to the rear surface 52A of the device inclusion housing 52. Therefore, as the arms 58 and 59 rotate around the second azimuth axis, the antenna reflector 31 can also rotate around the second azimuth axis.

  According to the basic configuration of the antenna device 1 described above, the antenna reflection plate 31 can be rotatably supported by the support 51 around the first azimuth axis, the second azimuth axis, and the elevation axis. The second azimuth axis is, for example, used for high-speed adjustment of the azimuth angle and is an additional configuration, so that the antenna reflection plate 31 can not be rotated around the second azimuth axis in the antenna device 1 Good. That is, the shaft 57 may be fixedly connected to the shaft holding box 56, the arm 58, and the arm 59.

  The cooling device (first cooling device) 71 is fixed to the outer surface of the wall 54B via a fixed shaft 71C so as to be freely rotatable relative to the wall (supporting piece) 54B of the yoke 54. As a result, the impact on the cooling device 71 due to the vibration or the like caused by the operation of rotating the antenna reflection plate 31 can be mitigated, and the requirement regarding the installation posture of the cooling device 71 can be satisfied.

  Further, the cooling device 71 has an outlet 71A for releasing cold air. The cool air discharged from the discharge port 71A is input (flows in) to the internal space SP54B-1 (third cold air flow path) of the wall 54B.

  In addition, the cooling device 71 has a suction port 71B that sucks in warm air (medium cold air described later). Warm air (moderate cold air described later) present in the internal space SP54B-2 of the wall 54B is taken into the cooling device 71 through the suction port 71B, and the cooling device 71 cools the taken-in hot air and discharges the cold air. Release from the outlet 71A.

  The wall portion 54B has a bearing portion 54B1 rotatably supporting the partial shaft 55A. The partial shaft 55A is cylindrical and has a cylindrical space SP55A.

  Further, the wall portion 54B has internal spaces SP54B-1 and SP54B-2 which are separated by partitions and independent of each other. The internal space SP54B-1 communicates with the cylindrical space SP55A of the partial shaft 55A. Therefore, the cylindrical space SP55A of the partial shaft 55A functions as a cold air flow path (second cold air flow path) in which the cold air of the internal space SP54B-1 flows in and is discharged to the internal space SP56 of the shaft holding box 56 through the cold air. Do.

  The shaft holding box 56 has four openings 56A, 56B, 56C, 56D. The shaft holding box 56 also has an internal space SP56. The internal space SP56 includes internal spaces SP56-1 and SP56-2 separated by partitions and independent of each other. The internal space SP56-1 is in communication with the openings 56A and 56B, and the internal space SP56-2 is in communication with the openings 56C and 56D.

  Further, in the shaft holding box 56, the partial shaft 55A is fixed such that the cylindrical space SP55A and the internal space SP56-1 communicate with each other through the opening 56A. Therefore, the cold air passing through the cylindrical space SP55A of the partial shaft 55A flows from the opening 56A into the internal space SP56-1, and the cold air flowing in is discharged from the opening 56B. Therefore, the internal space SP56-1 functions as a cold air flow path (first cold air flow path) which is discharged from the opening 56B through the cold air flowing in from the opening 56A.

  In the shaft holding box 56, the partial shaft 57A is fixed so that the cylindrical space SP57A of the partial shaft 57A and the internal space SP56-1 communicate with each other through the opening 56B. The other end of the partial shaft 57A opposite to the one end fixed to the shaft holding box 56 is rotatably held by the bearing 58A of the arm 58. The arm 58 has a cylindrical space SP58, and the cylindrical space SP58 communicates with the cylindrical space SP57A of the partial shaft 57A. Thereby, cold air of cylindrical space SP57A of partial shaft 57A flows in cylindrical space SP58 of arm 58. As will be described later, the cold air that has flowed into the cylindrical space SP58 of the arm 58 flows into the internal space SP52 of the device-containing housing 52, and is disposed in the internal space SP52 to cool the antenna communication device that emits heat. Used for

  In the shaft holding box 56, the partial shaft 57B is fixed such that the cylindrical space SP57B of the partial shaft 57B and the internal space SP56-2 communicate with each other through the opening 56C. The other end of the partial shaft 57B opposite to the one end fixed to the shaft holding box 56 is rotatably held by the bearing 59A of the arm 59. The arm 59 has a cylindrical space SP59, and the cylindrical space SP59 communicates with the cylindrical space SP57B of the partial shaft 57B. Thereby, the warm air of the cylindrical space SP59 of the arm 59 flows into the internal space SP56-2 of the shaft holding box 56 through the cylindrical space SP57B of the partial shaft 57B. Here, as described later, the warm air of the cylindrical space SP59 of the arm 59 is the warm air obtained by the cold air flowing into the internal space SP52 of the device-containing casing 52 being heated by the heat generation of the antenna communication device.

  In the shaft holding box 56, the partial shaft 55B is fixed such that the cylindrical space SP55B of the partial shaft 55B and the internal space SP56-2 communicate with each other through the opening 56D. As a result, the warm air that has flowed from the cylindrical space SP59 of the arm 59 into the internal space SP56-2 via the opening 56C is discharged to the cylindrical space SP55B of the partial shaft 55B via the opening 56D. Therefore, internal space SP56-2 is functioning as a warm air flow path (1st warm air flow path).

  The other end of the partial shaft 55B opposite to the one end fixed to the shaft holding box 56 is rotatably supported by the bearing 54C1 of the wall 54C of the yoke 54. The wall portion 54C has internal spaces SP54C-1 and SP54C-2 which are separated by partitions and independent of each other. The cylindrical space SP55B of the partial shaft 55B communicates with the internal space SP54C-1 of the wall 54C. Therefore, the warm air of the internal space SP56-2 of the shaft holding box 56 flows into the cylindrical space SP55B of the partial shaft 55B, and the warm air is discharged to the internal space SP54C-1 (third hot air flow passage) of the wall portion 54C through the warm air. , Functions as a warm air flow path (second warm air flow path).

  A cooling device (second cooling device) 72 is fixed to the outer surface of the wall 54 C of the yoke 54. The cooling device 72 is fixed to the outer surface of the wall 54C via a fixed shaft 72C so as to be freely rotatable relative to the wall 54C. As a result, the impact on the cooling device 72 due to vibration or the like caused by the operation of rotating the antenna reflection plate 31 can be mitigated, and the requirements regarding the installation posture of the cooling device 72 can be satisfied.

  The cooling device 72 has a suction port 72B communicating with the inner space SP54C-1 (third warm air flow passage) of the wall portion 54C and sucking in the warm air of the inner space SP54C-1. Further, the cooling device 72 has an outlet 72A communicating with the inner space SP54C-2 of the wall 54C and discharging cold air to the inner space SP54C-2. That is, the warm air existing in the internal space SP54C-1 of the wall portion 54C is taken into the cooling device 72 from the suction port 72B, and the cooling device 72 cools the taken-in warm air to discharge cold air from the outlet 72A into the internal space SP54C. Release to -2.

  The internal space SP54C-2 of the wall 54C and the internal space SP54B-2 of the wall 54B communicate with the internal space SP54A of the support base 54A. Thus, the outlet 72A of the cooling device 72 and the suction port 71B of the cooling device 71 are connected by the inner space SP54C-2, the inner space SP54A, and the inner space SP54B-2. That is, the internal space SP54C-2, the internal space SP54A, and the internal space SP54B-2 function as a "cooling device flow path" connecting the cooling device 72 and the cooling device 71.

  Here, the cooling device 72 cools the warm air of the internal space SP54C-1 of the wall portion 54C, and discharges cold air (actually, medium cold air) to the flow passage between the cooling devices. Then, the cooling device 71 further cools the cold air discharged from the cooling device 72, that is, the medium cold air of the flow path between the cooling devices, and discharges it to the internal space SP54B-1 of the wall portion 54B. As described above, since the cooling device 72 and the cooling device 71 can cooperate to send cold air to the device inclusion housing 52, the cooling capacity can be further improved.

  With the configuration of the support 51 described above, as shown in FIG. 6, the cold air discharged from the cooling device 71 is an internal space SP54B-1, a cylindrical space SP55A, an internal space SP56-1, a cylindrical space SP57A, And, it flows into the internal space SP52 of the device-containing casing 52 via the cylindrical space SP58. Then, the warm air heated by the heat generation of the antenna communication device disposed in the device-containing casing 52 is released to the cylindrical space SP59, and the cylindrical space SP59, the cylindrical space SP57B, the internal space SP56-2, the cylindrical The cooling device 72 is input through the space SP55B and the internal space SP54C-1. FIG. 6 schematically shows the flow of air inside the support 51. As shown in FIG.

Further, the device inclusion housing 52 includes an internal space SP 52-1 and an internal space SP 52-2 as the internal space SP 52. The internal space SP52-1 communicates with the cylindrical space SP58 via the opening 52A1. Thereby, the cold air | gas discharge | released from the cooling device 71 flows in internal space SP52-1.

  7 and 8 are views schematically showing an example of the internal configuration of the device-containing casing. FIG. 7 is a view corresponding to the cross-sectional view of FIG. 5, and FIG. 8 is a view of the device inclusion housing 52 from the + x side.

  An antenna communication device 80 is disposed at the center of the internal space SP 52-1 of the device inclusion housing 52. An assist fan 52B is disposed at a position closer to the opening 52A1 than the central portion of the internal space SP52-1 of the device inclusion housing 52, that is, on the upstream side of the central portion of the internal space SP52-1 of the device inclusion housing 52. It is set up. The assist fan 52B draws the cold air flowing from the opening 52A1 and sends it to the central portion of the internal space SP52-1. As a result, the static pressure of the cold air in the internal space SP52-1 can be increased, so the cooling efficiency can be improved.

  An assist fan 52C is disposed at a position closer to the opening 52A2 than the central portion of the internal space SP52-1 of the device inclusion housing 52, that is, on the downstream side of the central portion of the internal space SP52-1 of the device inclusion housing 52. It is set up. The assist fan 52C is disposed, for example, in the opening (warm air discharge port) 52A2. Then, the assist fan 52C pulls the warm air heated by the antenna communication device 80 at the central portion of the internal space SP52-1, and sends it to the cylindrical space SP59 of the arm 59. Accordingly, the warm air heated by the antenna communication device 80 at the central portion of the internal space SP52-1 can be efficiently released from the internal space SP52-1.

  The internal space SP52-2 is disposed on the opposite side of the antenna reflection plate 31 with the internal space SP52-1 interposed therebetween, and is in communication with the internal space SP52-1 through the communication hole 52D. As a result, since the heat insulating air layer can be formed in the device inclusion housing 52 by the internal space SP 52-2, the cooling efficiency can be further improved.

  A fan of the LNA 81 is disposed in the communication hole 52D. Thereby, the cold air which flows into internal space SP52-2 from internal space SP52-1 can be utilized for cooling of LNA81 with especially large calorific value.

  Here, as described above, the antenna communication device 80 is disposed at the central portion of the internal space SP 52-1 of the device inclusion housing 52.

The power supply device 86 is a power supply device that supplies power to devices other than the LNA 81. The optical transceiver 87 is a device that transmits and receives an optical signal via an optical cable.

  In the arrangement example in FIG. 8, the amplifier power supply device 82-1 and the TRK RX 84 are disposed in the + y side region of the internal space SP 52-1. The amplifier power supply apparatus 82-2, the network switch 83, the modem 85, the power supply apparatus 86, and the optical transceiver 87 are disposed in the -y side area of the internal space SP 52-1. And LNA81 shown by FIG. 7 is arrange | positioned by the center area | region pinched | interposed into the + y side area | region of internal space SP52-1, and the-y side area | region. In the internal space SP52-1, by properly arranging the straightening vanes, cold air drawn by the assist fan 52B is distributed in a well-balanced manner to the -y side region, the central region, and the + y side region. .

  Here, as shown in FIG. 4, the power output device (for example, a motor) M1 that outputs a rotational driving force for rotating the shaft 55 and the shaft holding box 56 about the elevation axis is the inside of the wall 54C of the yoke 54. It may be disposed in the space SP54C-2 (that is, the flow path between the cooling devices). Thereby, the motive power output device M1 can also be operated at an appropriate temperature.

  The rotational driving force output from the power output device M1 is transmitted to the shaft 55 and the shaft holding box 56 by the power transmission unit 60. The power transmission unit 60 includes, for example, reduction gears 61 and 62 and a gear 63, as shown in FIG. The gear 63 is fixed to the shaft holding box 56 so as to surround the shaft 55B (that is, the elevation shaft).

  Furthermore, as shown in FIG. 4, the power output device (for example, the motor) M2 that outputs the rotational driving force for rotating the arms 58 and 59, the device inclusion housing 52, and the antenna main body 3 around the second azimuth axis It may be disposed in the internal space SP56-1 of the holding box 56. Thereby, the motive power output device M2 can also be operated at an appropriate temperature.

  As described above, according to the first embodiment, in the antenna support device 5, the support 51 includes the device reflection case 31 and the device-containing casing 52 rotatably supported by the support 51. The device inclusion housing 52 has an internal space SP 52 which contains the antenna communication device 80, and also has an opening (cold air input port) 52A1 for inputting cold air discharged from the cooling device 7 into the internal space SP 52 and the antenna communication device 80. There is an opening (warm air discharge port) 52A2 for discharging the warm air obtained by heating the cold air inputted from the opening by heat generation toward the cooling device 7.

  With the configuration of the antenna support device 5, a cold air input port for inputting cold air discharged from the cooling device 7 and warm air to the cooling device are discharged to the device containing case 52 which includes the antenna communication device 80 in the internal space. By providing the warm air discharge port, a large amount of cold air can be flowed into the device-containing casing 52, and the antenna communication device 80 can be sufficiently cooled even in a large antenna device. As a result, it is possible to realize the antenna support device 5 that can improve the versatility of the antenna device regardless of the area where the antenna device 1 is installed and the weather.

  Further, in the antenna support device 5, the support 51 has a shaft holding box 56 which holds the shaft 55 and is rotatably supported by the shaft 55. The shaft holding box 56 discharges the first cold air flow path (internal space SP56-1) that discharges cold air discharged from the cooling device 7 to the opening (cold air input port) 52A1, and discharges it from the opening (warm air discharge port) 52A2. And the first warm air flow passage (internal space SP56-2) to be discharged toward the cooling device 7 through the warm air that has been stored.

  With the configuration of the antenna support device 5, the shaft holding box 56 can be used as a flow passage for cold air and warm air, so there is no need to separately provide a flow passage structure in addition to the antenna device configuration. Space efficiency can be improved.

  Further, in the antenna support device 5, the shaft 55 has a partial shaft 55A and a partial shaft 55B. The partial shaft 55A is cylindrical and has a second cold air flow passage (cylindrical space SP55A) that discharges cold air to the first cold air flow passage (internal space SP56-1) through the cold air discharged from the cooling device 7. doing. The partial shaft 55B is cylindrical and discharges warm air toward the cooling device 7 through warm air discharged from the first warm air flow passage (internal space SP56-2) (cylindrical space SP55B) have.

  Since the shaft 55 which makes the antenna reflection plate 31 rotatable can be used as a channel for cold air and warm air by the antenna supporting device 5, it is not necessary to separately provide a channel structure in addition to the antenna device configuration. Thus, cost efficiency and space efficiency can be improved.

  Further, in the antenna support device 5, the support 51 has a pair of wall portions (first support pieces) 54B and wall portions (second support pieces) 54C that respectively support the partial shaft 55A and the partial shaft 55B. The wall portion 54B communicates with the second cold air flow passage (cylindrical space SP55A) and discharges the cold air to the second cold air flow passage through the cold air discharged from the cooling device 71 (internal space SP54B-1 ) Is inside. The wall portion 54C communicates with the second warm air flow passage (cylindrical space SP55B) and discharges warm air to the cooling device 72 through the warm air discharged from the second warm air flow passage (internal space SP54C-1 ) Inside.

  Since the internal space of the pair of wall 54B and wall 54C supporting the shaft 55 that makes the antenna reflection plate 31 rotatable can be used as a flow path by the configuration of the antenna support device 5, the antenna device configuration In addition to the above, it is not necessary to separately provide a flow path structure, so cost efficiency and space efficiency can be improved.

  And the cooling device 71 and the cooling device 72 are mutually connected by the flow path between cooling devices. Then, the cooling device 72 is disposed on the outer surface of the wall portion (second support piece) 54C, receives the warm air discharged from the third warm air flow passage (the internal space SP54C-1), and cools the cold air Release to the interflow channel. The cooling device 71 is disposed on the outer surface of the wall portion (first support piece) 54B, and the cold air discharged from the cooling device 72 is input through the inter-cooling device flow path and released from the cooling device 72. The cold air further cooled than the cold air is discharged to the third cold air flow path (internal space SP54B-1). Thereby, since a plurality of cooling devices 71 and 72 can be made to cooperate and cold air can be sent to the device-containing casing 52, the cooling capacity can be further improved.
