Description

Technical Field

[0001] This utility model relates to the field of frequency downconverter technology, specifically an integrated frequency downconverter. Background Technology

[0002] The working principle of a satellite antenna receiving satellite television is to use the satellite antenna to collect weak satellite signals and reflect the satellite signals to a low-noise down-conversion device installed at the focal point of the dish antenna.

[0003] Existing patent (publication number: CN206060692U) discloses an integrated frequency downconverter, including a square shell-shaped high-frequency head with an opening at the bottom and an output head at the top. A flat housing is located on the upper part of the high-frequency head, with a groove on the front side containing an integrated circuit board. The back of the housing is flush with a mounting plane on one side of the high-frequency head. The bottom opening of the high-frequency head is mechanically compressed into a cylindrical waveguide, within which are a horizontal probe for receiving horizontally polarized signals and a vertical probe for receiving vertically polarized signals. The purpose of this invention is to provide an integrated frequency downconverter that is simple in structure, low in cost, and easy to use.

[0004] However, the aforementioned frequency downconverters usually need to be connected to a feeder and bracket during use. Common feeder brackets are often fixed to the bottom of the downconverter by bolts, which is not very effective. The downconverters are often installed outdoors in unobstructed areas, and strong winds can easily cause the bracket to vibrate, causing the downconverter to slip and shift, affecting the signal reception. Furthermore, during use, because they are exposed to the outdoors, rain and moisture can easily enter the interior through the connection port, causing damage to the circuit board.

A moisture-absorbing cotton 4 is provided on the inner wall of the circuit board mounting housing 201. The moisture-absorbing cotton 4 can absorb the moisture inside the circuit board mounting housing 201. The ceramic heating element 3 can raise the temperature inside the circuit board mounting housing 201. At the same time, the moisture-absorbing cotton 4 can avoid the ceramic heating element 3 from directly baking the circuit board and can dry the moisture inside the absorbent surface, ensuring the recycling of the moisture-absorbing cotton 4. A humidity sensor 11 is installed on the inner bottom wall of the circuit board mounting housing 201. The humidity sensor 11 can monitor the humidity inside the circuit board mounting housing 201. A frequency reduction circuit board 8 and a temperature control circuit board 9 are installed on the other inner wall of the circuit board mounting housing 201. The moisture-absorbing cotton 4 is located between the ceramic heating element 3 and the frequency reduction circuit board. The temperature control circuit board 9 can automatically adjust the temperature of the ceramic heating element 3 according to the feedback of the humidity sensor 11 to maintain a dry environment inside the circuit board mounting housing 201.

[0038] Please see Figure 2 , Figure 6 and Figure 7 The outer surface of the feed plate 1 is provided with a set of circumferentially arranged connection holes 105, which facilitates connection with the mounting bracket. A photovoltaic panel 5 is provided on one side of the circumferential surface of the feed plate 1. An energy storage shell 6 is installed at the bottom of the photovoltaic panel 5. A battery module 7 is installed inside the energy storage shell 6. The photovoltaic panel 5 and the battery module 7 are electrically connected. The battery module 7 can be used to store electricity. The temperature control circuit board 9 is electrically connected to the ceramic heating element 3 and the humidity sensor 11. Through the electrical connection, the temperature control circuit board 9 receives humidity data in real time and controls the working status of the ceramic heating element 3 to achieve intelligent temperature and humidity regulation and prevent the frequency reducer circuit board 8 from being damaged by moisture or overheating.

[0039] Please see Figure 1 , Figure 2 and Figure 6An adjustment component 10 is provided on the circumferential surface of the feed disk 1. The adjustment component 10 includes a mounting base 1001, which is fixedly connected to the feed disk 1. An adjustment shaft 1002 is rotatably connected between the two inner side walls of the mounting base 1001. The two ends of the adjustment shaft 1002 are fixedly connected to the same mounting bracket 1003. The photovoltaic panel 5 is fixedly connected to the mounting bracket 1003.

Through the self-locking characteristics of the worm gear 1004 and worm 1006, the photovoltaic panel 5 is stably fixed after the angle is adjusted, ensuring efficient energy collection under the optimal illumination angle.

[0040] In this embodiment, an integrated frequency reducer maintains a dry environment inside the circuit board mounting housing 201 through the linkage of humidity sensor 11, temperature control circuit board 9, and ceramic heating element 3. This effectively prevents damage to the frequency reducer circuit board 8 caused by moisture and improves its service life. The photovoltaic panel 5 and energy storage shell 6 arranged on the circumferential surface of the feed disk 1 can store electricity, reducing dependence on external power and providing power to the ceramic heating element 3. Furthermore, the worm gear 1004 and worm 1006 adjustment assembly 10 allow users to adjust the angle of the photovoltaic panel 5 according to the actual installation angle and position of the frequency reducer body 2, ensuring power generation efficiency. The insertion and engagement of the fixing rod 103 and the fixing hole 203 supports tool-free disassembly and assembly of the frequency reducer body 2, facilitating equipment maintenance or repair.

[0041] The working principle of the above embodiment is as follows: The frequency reducer body 2 is inserted through the mounting ring 101 on the feed plate 1. The guide key on the inner wall of the mounting ring 101 cooperates with the guide groove 202 at the bottom of the frequency reducer body 2 for guidance. When the frequency reducer body 2 is inserted along the guide key, its bottom arc-shaped design contacts the rounded corner at the end of the fixing rod 103, squeezing the fixing rod 103 to slide outward. When it is inserted to the preset depth, the spring 104 resets and pushes the fixing rod 103 into the fixing hole 203 at the bottom of the frequency reducer body 2, forming an elastic locking structure. The humidity sensor 11 monitors the humidity inside the housing in real time. When the humidity exceeds the standard, the signal is transmitted to the temperature control circuit board 9. The temperature control circuit board 9 drives the ceramic heating element 3 to heat up. During the heating process, the moisture-absorbing cotton 4 between the ceramic heating element 3 and the frequency reduction circuit board absorbs heat and releases the absorbed moisture. After the humidity decreases, the sensor feedback signal stops the heating, and the moisture-absorbing cotton 4 restores its moisture-absorbing capacity, realizing recycling. The photovoltaic panel 5 on the side of the feed plate 1 converts solar energy into electrical energy, which is stored through the battery module 7. The rotating handle 1007 drives the worm gear 1006, which drives the worm wheel 1004 and the adjusting shaft 1002 to rotate, adjusting the pitch angle of the photovoltaic panel 5 mounting bracket 1003. The self-locking characteristics of the worm wheel 1004 and the worm gear 1006 ensure that the angle is fixed after adjustment.
