Description
本発明は、衛生電波を受信するためのパラボラアンテナ用の融雪装置に関するものである。 The present invention relates to a snow melting device for a parabolic antenna for receiving sanitary radio waves.
一般にパラボラアンテナは、衛星電波を受けるための皿型のアンテナ反射板を有し、このアンテナ反射板で反射させて受信した番組放送データをテレビなどの受信端末に送って視聴者が視聴するものである。ところが積雪の多い地域では、アンテナ反射板に雪が付着したり、あるいは、アンテナ反射板に付着した水滴が凍って表面に不規則な凹凸の氷の層を作ることで、ＬＮＢ（衛星通信ダウンコンバータ）に収束される電波の位相が遅れて受信レベルの低下を引き起こすものであった。これにより、受信端末側ではモニターの映像にノイズが生じて視聴しづらくなり、家主が屋外に出てアンテナ反射板に付着した雪や氷を取り除かなければならない不都合があった。 In general, a parabolic antenna has a dish-shaped antenna reflector for receiving satellite radio waves, and the program broadcast data reflected by the antenna reflector is sent to a receiving terminal such as a TV for viewing by a viewer. is there. However, in areas where there is a lot of snow, LNB (satellite communication downconverter) can be created by attaching snow on the antenna reflector or by freezing water droplets attached to the antenna reflector to form irregular irregular ice layers on the surface. The phase of the radio wave that converges on is delayed, causing the reception level to decrease. As a result, noise is generated on the monitor image on the receiving terminal side, making it difficult to view, and there is a problem that the landlord has to go outside and remove snow and ice attached to the antenna reflector.

そこで、上記のような不都合を解消するため、アンテナ反射板に熱線を内蔵したものや、あるいは、アンテナ反射板の表面（受信面）や裏面側に熱線入りのヒーターを貼り付けるようなものがあった。ところが、アンテナ反射板に熱線を内蔵したものは、融雪性能は確保できるものの製造コストが嵩んで大変高価になり、しかも、破損や故障時には取り外して製造元に修理を依頼しなければならないため、普及に至っていない。一方、熱線を這わせたヒーターを貼り付けるものの場合には、ＬＮＢへの供給電力のみではアンテナ反射板の全体をヒーターでカバーできず、このことから、期待した融雪効果が得られず、受信端末における視聴状態の改善を安定的に図れない不都合があった。
本発明は、上記課題を鑑みてなされたものであり、低電力でアンテナ反射板全体にわたり融雪効果が期待でき、しかも、安価なパラボラアンテナ用融雪装置を提供することにある。
Therefore, in order to eliminate the inconveniences described above, there are ones in which the antenna reflector has a built-in heat wire, or those in which a heater with a heat wire is attached to the front surface (receiving surface) or the back surface of the antenna reflector. It was. However, the antenna reflector with a built-in heat wire can ensure snow melting performance, but the manufacturing cost increases and it becomes very expensive, and it must be removed and requested to be repaired by the manufacturer in case of damage or failure. Not reached. On the other hand, in the case of attaching a heater with a hot wire, the whole antenna reflector cannot be covered with the heater only with the power supplied to the LNB, and thus the expected snow melting effect cannot be obtained, and the receiving terminal There is a disadvantage that the viewing state cannot be stably improved.
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a snow melting device for a parabolic antenna that can be expected to have a snow melting effect over the entire antenna reflector with low power.
本発明のうち請求項１記載の発明は、複数の発熱部と、同軸分離器と、温度スイッチと、間欠スイッチとを備えており、発熱部は、アンテナ反射板裏面に取り付けてあり、同軸分離器は、電源からＬＮＢと各発熱部に供給する電力を分配し、温度スイッチは、外気温が２℃以下となったときに、ＯＮ／ＯＦＦを切り替えて同軸分離器から各発熱部に対する電力の供給と停止を制御するものであり、間欠スイッチは、温度スイッチが切り替えられて電力が供給されたときに、アンテナ反射板裏面に取り付けられた一方の発熱部と他方の発熱部に対して交互にＯＮ／ＯＦＦの切り替えをすることを特徴とする。
The invention according to claim 1 of the present invention includes a plurality of heat generating portions, a coaxial separator, a temperature switch, and an intermittent switch, and the heat generating portion is attached to the back surface of the antenna reflector, and is coaxially separated. The power supply distributes the power supplied from the power supply to the LNB and each heat generating part, and the temperature switch switches ON / OFF when the outside air temperature becomes 2 ° C. or lower, and the power supply from the coaxial separator to each heat generating part Supplying and stopping are controlled, and the intermittent switch is alternately applied to one heating part and the other heating part attached to the back of the antenna reflector when the temperature switch is switched and power is supplied. It is characterized by switching ON / OFF.
本発明の請求項２記載の発明では、アンテナ反射板裏面に発熱部を取り付けたときに、一方の発熱部の外周側に他方の発熱部が配置されることを特徴とする。 The invention according to claim 2 of the present invention is characterized in that when the heat generating portion is attached to the back surface of the antenna reflector, the other heat generating portion is arranged on the outer peripheral side of one heat generating portion.
本発明のうち請求項１記載の発明によれば、アンテナ反射板裏面の複数箇所に発熱部を取り付け、さらに、各発熱部への電力供給を交互にＯＮ／ＯＦＦする間欠スイッチを有することにより、外気温が２℃以下まで下がり温度スイッチがＯＮとなって間欠スイッチの一方の発熱部が発熱する。このことから、他方の発熱部がＯＦＦの状態にあっても余熱があるため、アンテナ反射板全体が暖められた状態となることから、別途専用の電源を増設する必要がなく、ＬＮＢに供給している放送受信用の電源のみで確実にアンテナ反射板の表面（受信面）側全体の融雪が可能となる。したがって、降雪時であっても受信端末では支障なく視聴できることになり、低電力且つ長期的に使用できるパラボラアンテナ用融雪装置を提供できる。 According to the invention described in claim 1 of the present invention, the heat generating part is attached to a plurality of locations on the back surface of the antenna reflector, and further, the power supply to each heat generating part is alternately turned ON / OFF, The outside air temperature falls to 2 ° C. or lower, the temperature switch is turned on, and one heat generating portion of the intermittent switch generates heat. For this reason, since the remaining heat is generated even when the other heat generating part is in the OFF state, the entire antenna reflector is in a warmed state. Therefore, it is not necessary to add a dedicated power source separately and supply it to the LNB. It is possible to reliably melt snow on the entire surface (receiving surface) of the antenna reflector with only the broadcast receiving power source. Therefore, even when it is snowing, the receiving terminal can view without trouble, and a snow melting apparatus for a parabolic antenna that can be used for a long time with low power can be provided.
本発明のうち請求項２記載の発明によれば、発熱部をアンテナ反射板裏面における内周部と外周部にそれぞれ取り付けてあることで、内周側と外周側の発熱を交互に切り替えて行うことで一層効率的な融雪効果が期待できる。 According to the second aspect of the present invention, the heat generating portions are attached to the inner peripheral portion and the outer peripheral portion on the back surface of the antenna reflector, respectively, so that heat generation on the inner peripheral side and the outer peripheral side is alternately switched. Therefore, more efficient snow melting effect can be expected.
以下に、図面に基づいて本実施によるパラボラアンテナ用融雪装置の実施の形態を説明する。また、本実施によるパラボラアンテナ用融雪装置は具体的に、パラボラアンテナのアンテナ反射板６裏面に貼り付けた状態について説明するものである。
本実施によるパラボラアンテナ用融雪装置は、図１および図２のように、パラボラアンテナのアンテナ反射板６の裏面側に、一面側が粘着層であり他面側が撥水性と断熱性を有する縦長ほぼリング状をなす断熱素材で形成された取付シート９と、取付シート９の粘着層側にリング状に配置される内側発熱部１（一方の発熱部）と、内側発熱部１の外周に配置される同じく縦長ほぼリング状をなす外側発熱部２（他方の発熱部）と、内外の各発熱部１，２に電力供給をするためのケーブル１１とからなっている。また、内側発熱部１と外側発熱部２の電源７は、上記ケーブル１１を同軸分離器３に接続し、その同軸分離器３から分離した電圧により内外の各発熱部１，２の発熱がなされるものである。また、同軸分離器２には、ＬＮＢ８に対しても通電されており、さらに、同軸分離器５には温度スイッチ４と間欠スイッチ５が内蔵されている（図３参照）。尚、図１中符号１４はチューナーである。
Hereinafter, embodiments of a snow melting apparatus for parabolic antennas according to the present embodiment will be described with reference to the drawings. Moreover, the snow melting apparatus for parabolic antennas according to the present embodiment will specifically describe a state where the parabolic antenna is attached to the back surface of the antenna reflector 6.
As shown in FIGS. 1 and 2, the snow melting apparatus for a parabolic antenna according to the present embodiment has a vertically long ring having an adhesive layer on one side and water repellency and heat insulation on the other side on the back side of the antenna reflector 6 of the parabolic antenna. A heat-sealable attachment sheet 9, an inner heating part 1 (one heating part) disposed in a ring shape on the adhesive layer side of the mounting sheet 9, and an outer periphery of the inner heating part 1. Similarly, it is composed of an outer heat generating portion 2 (the other heat generating portion) that is substantially vertically long and a cable 11 for supplying electric power to the inner and outer heat generating portions 1 and 2. Further, the power source 7 for the inner heat generating portion 1 and the outer heat generating portion 2 connects the cable 11 to the coaxial separator 3, and the internal and external heat generating portions 1 and 2 generate heat by the voltage separated from the coaxial separator 3. Is. The coaxial separator 2 is also energized to the LNB 8, and the coaxial separator 5 includes a temperature switch 4 and an intermittent switch 5 (see FIG. 3). In FIG. 1, reference numeral 14 denotes a tuner.
本実施による内側発熱部１と外側発熱部２は、図２のように、取付シート９の粘着層に熱線１ａ，２ａを這わせるものであり、具体的に、１枚の取付シート９の内周側と外周側にそれぞれ熱線を這わせ、取付シート９の全体に亘って均一に発熱されるように構成してある。また、熱線の両端はケーブル１１と接続してあり、このケーブル１１を介して電源７から電力供給される。
尚、図２中の符号１３は、アンテナ反射板６を支える支持バーである。
The inner heating part 1 and the outer heating part 2 according to the present embodiment are configured such that the heat rays 1a and 2a are put on the adhesive layer of the mounting sheet 9 as shown in FIG. Heat wires are provided on the peripheral side and the outer peripheral side, respectively, so that heat is uniformly generated over the entire mounting sheet 9. Further, both ends of the hot wire are connected to the cable 11, and power is supplied from the power source 7 via the cable 11.
Note that reference numeral 13 in FIG. 2 denotes a support bar that supports the antenna reflector 6.
間欠スイッチ５は、図３のように、上記した内側発熱部１と外側発熱部２における所定時間周期でのＯＮ／ＯＦＦの切り替えを制御するものである。そして、外気温が下がって温度スイッチ４が「入」となったとき、コンデンサ１２が連動して間欠スイッチ５におけるＯＮ／ＯＦＦ切換制御に応じ、内側発熱部１と外側発熱部２のうちの一方の発熱部１の発熱時間と他方の発熱部２の発熱停止時間がそれぞれ設定される。また、「外側発熱部（内側発熱部）の発熱時間」の設定を変更したい場合には、コンデンサ１２の容量と電圧を適宜調整することで自在に設定できる。 As shown in FIG. 3, the intermittent switch 5 controls ON / OFF switching at a predetermined time period in the inner heat generating portion 1 and the outer heat generating portion 2 described above. When the outside air temperature decreases and the temperature switch 4 is “ON”, the capacitor 12 operates in conjunction with one of the inner heating unit 1 and the outer heating unit 2 according to the ON / OFF switching control in the intermittent switch 5. The heat generation time of the heat generation unit 1 and the heat generation stop time of the other heat generation unit 2 are set. Further, when it is desired to change the setting of “the heat generation time of the outer heat generating portion (inner heat generating portion)”, it can be freely set by appropriately adjusting the capacity and voltage of the capacitor 12.
このように形成した本実施によるパラボラアンテナ用融雪装置の性能について、図４と図５（ａ）（ｂ）に基づいて説明する。
まず、本実施によるアンテナ融雪装置の起動後、最初の１０秒間でアンテナ反射板６裏面に取り付けてある外側発熱部２が発熱する。そして、間欠スイッチ５における切り替えにより外側発熱部２に対する通電をＯＦＦとし、内側発熱部１に１０秒間通電することで、内側発熱部１の発熱と外側発熱部２の余熱によりアンテナ反射板６が暖められる。この内側発熱部１と外側発熱部２とを交互に発熱させることを温度スイッチ４が「入」の状態の間に繰り返すことで、アンテナ反射板６全体を発熱するのとほぼ同等の効果が得られる。したがって、ＬＮＢ８と同等の消費電力でアンテナ反射板６の融雪がなされるため、低電力使用が可能となる。上記のような交互に作動を繰り返すことで、図４のように、本実施によるパラボナアンテナ融雪装置を取り付けていないもの、つまりは、図中の上側に示すアンテナ反射板（アンテナ融雪装置を取り付けていないもの）では、雪が数ｃｍ積もった状態にあるが、図中の下側に示す本実施によるパラボラアンテナ用融雪装置を取り付けたものでは、表面（受信面）側に雪や氷の付着がない状態となる。このときに、図５（ａ）（ｂ）のように、本実施によるパラボラアンテナ用融雪装置を取り付けてあるアンテナ反射板６の表面（受信面）側の温度は約８℃を計測しており、測定当日の外気温よりも１０℃ほど高いことから、アンテナ反射板６表面に付着した雪の接触部分を溶かすことによって、アンテナ反射板６表面の氷結防止はもちろん、付着した雪がアンテナ反射板６表面から滑落しやすい状態となることが推測される。
The performance of the snow melting apparatus for parabolic antennas according to the present embodiment formed as described above will be described with reference to FIGS. 4 and 5A and 5B.
First, after the start of the antenna snow melting device according to the present embodiment, the outer heat generating portion 2 attached to the back surface of the antenna reflector 6 generates heat in the first 10 seconds. Then, the switching of the intermittent switch 5 turns off the energization of the outer heating part 2 and energizes the inner heating part 1 for 10 seconds, so that the antenna reflector 6 is warmed by the heat generated by the inner heating part 1 and the remaining heat of the outer heating part 2. It is done. By repeating the heat generation of the inner heat generating portion 1 and the outer heat generating portion 2 while the temperature switch 4 is in the “ON” state, substantially the same effect as the heat generation of the entire antenna reflector 6 is obtained. It is done. Therefore, since the antenna reflector 6 is melted with power consumption equivalent to that of the LNB 8, low power use is possible. By repeating the operation as described above, as shown in FIG. 4, the parabona antenna snow melting device according to the present embodiment is not attached, that is, the antenna reflector (the antenna snow melting device is attached on the upper side in the figure). No snow), but snow is piled up several centimeters, but with the parabolic antenna snow melting device shown in the lower part of the figure attached, there is no snow or ice on the surface (receiving surface) side. It becomes a state. At this time, as shown in FIGS. 5 (a) and 5 (b), the temperature on the surface (receiving surface) side of the antenna reflector 6 to which the parabola antenna snow melting device according to the present embodiment is attached is measured at about 8 ° C. Since the outside temperature on the day of measurement is about 10 ° C., melting the contact portion of the snow adhering to the surface of the antenna reflector 6 prevents the ice on the surface of the antenna reflector 6 as well as the adhering snow from the antenna reflector 6. It is estimated that it will be in a state where it is easy to slide off from the surface.
本実施によるパラボラアンテナ用融雪装置は、上記した実施形態の他、発熱部１，２や取付シート９の形状や配置パターン、配置する数やアンテナ反射板６に対する大きさについては特に限定するものではなく、アンテナ反射板６裏面側に均等に配されるものであればよい。また、取付シート９の素材については、アンテナ反射板６裏面に取り付けたときの外側面（反粘着面側）が断熱性や撥水性、防水性を有するものを適用したり、あるいは、ウレタンなどの断熱材の露出面に防水・撥水塗料によるコーティングが施されているものなどが使用される。 The snow melting apparatus for a parabolic antenna according to the present embodiment is not particularly limited with respect to the shape and arrangement pattern of the heat generating parts 1 and 2 and the mounting sheet 9, the number to be arranged, and the size with respect to the antenna reflector 6 in addition to the above-described embodiment. However, what is necessary is just to distribute | arrange equally to the antenna reflector 6 back surface side. In addition, as for the material of the mounting sheet 9, the outer surface (the anti-adhesive surface side) when mounted on the back surface of the antenna reflector 6 is applied with heat insulation, water repellency, waterproofing, or urethane. For example, the exposed surface of the heat insulating material is coated with a waterproof / water-repellent paint.
