Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and in particular to an outdoor solar-powered data link relay station. Background Technology

[0002] Currently, outdoor solar data links typically mount the antenna on the top of the pole to reduce obstruction and interference, and maximize signal coverage and quality. The outdoor cabinet is installed in the middle of the pole for easy maintenance and to balance the structural load. A long RF cable is then run out from inside the outdoor cabinet to connect the data link and the antenna, which increases the loss of the RF cable. Furthermore, the long cable causes voltage fluctuations to have a greater impact on the equipment, thus reducing the performance of the equipment. Utility Model Content

[0003] Based on the above analysis, this utility model aims to provide an outdoor solar data link relay station to solve the problem in the prior art where the excessively long distance between the outdoor solar data link and the antenna increases the loss of radio frequency cables and reduces the performance of the equipment.

[0004] The objective of this utility model is mainly achieved through the following technical solutions:

[0005] An outdoor solar-powered data link relay station includes a pole, an outdoor cabinet, and an antenna;

[0006] The outdoor cabinet includes an outdoor cabinet located on top of the pole; the antenna is located on top of the outdoor cabinet.

[0007] Furthermore, the pole includes a pole body and a top seat, with the top seat located on the upper part of the pole body; the outdoor cabinet is located on the top seat.

[0008] Furthermore, it also includes a solar panel, which is obliquely mounted on the top base, and the solar panel and the outdoor cabinet are respectively mounted on opposite sides of the top base; the height of the antenna is greater than the height of the solar panel.

[0009] Furthermore, the outdoor cabinet also includes a data link module, which is located in the upper part of the outdoor cabinet.

[0010] Furthermore, the outdoor cabinet also includes an antenna surge protector, which is located in the upper part of the outdoor cabinet; one end of the antenna surge protector is connected to the data link module, and the other end of the antenna surge protector is connected to the antenna via an RF cable.

[0011] Furthermore, the outdoor cabinet also includes an MPPT controller; the MPPT controller is connected to the solar panel.

[0012] Furthermore, the outdoor cabinet also includes a surge protector and a low-voltage circuit breaker connected together; the surge protector is connected to the MPPT controller, and the low-voltage circuit breaker is connected to the data link module.

[0013] Furthermore, the outdoor cabinet also includes a battery, which is connected to the MPPT controller.

[0014] Furthermore, the outdoor cabinet includes a cabinet body and a door panel, and a waterproof sealing strip is provided between the door panel and the cabinet body.

[0015] Furthermore, the support rod has a hollow structure, and the ratio of the thickness of the support rod to the length of the support rod is 0.1%-0.3%.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] (1) Compared to the prior art where the outdoor cabinet is placed in the middle of the pole and a relatively long RF cable is used to connect the outdoor cabinet and the antenna, the outdoor cabinet in this invention is placed at the top of the pole, minimizing the length of the RF cable. When the outdoor cabinet is in the middle of the pole, the RF cable length is 4-6 meters; when the outdoor cabinet is placed at the top of the pole, the RF cable length is reduced to 0.3 meters, reducing cable loss and improving the data transmission performance of the equipment. This invention is mainly used for UAV data transmission. It can be installed and used to fill blind spots on the fixed route of the UAV, or it can be used as a relay station for UAVs to achieve long-distance communication.

[0018] (2) This utility model has a solar panel installed on the top base, which is positioned opposite to the outdoor cabinet, which helps stabilize the center of gravity of the pole; the data link module can be charged by solar energy and work continuously for 24 hours, achieving the technical effect of energy saving and consumption reduction. In this utility model, the height of the antenna is greater than the height of the solar panel, which on the one hand avoids the solar panel from blocking the signal, and on the other hand reduces the electromagnetic interference of the solar panel to the antenna.

[0019] (3) The data link is located in the upper part of the outdoor cabinet to shorten the distance to the antenna and reduce cable loss; the antenna surge protector is located between the data link and the antenna for lightning protection to protect the data link module; the surge protector and low voltage circuit breaker are located between the MPPT controller and the data link module for protecting the data link module; the battery is used to power the data link module and stores the electrical energy of the solar cell through the MPPT controller.

[0020] (4) A waterproof sealing strip is installed between the cabinet body and the door panel of the outdoor cabinet to prevent the equipment from being affected by weather changes.

[0021] (5) The support pole has a hollow structure. In order to improve the structural strength and balance of the support pole, the height of the support pole is reduced, and the ratio of the thickness of the support pole to the length of the support pole is 0.1%-0.3%. The bottom of the outdoor cabinet is about 2.3 meters away from the ground, which is a distance that is generally inaccessible to adults. This avoids damage to the outdoor cabinet caused by human factors, while reducing the height of the support pole and increasing its strength.

[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] A specific embodiment of this utility model is as follows: Figure 1 As shown, an outdoor solar-powered data link relay station is disclosed, including a pole 1, an outdoor cabinet 2, and an antenna 3.

[0033] The outdoor cabinet 2 includes an outdoor cabinet 2, which is located on top of the pole 1; the antenna 3 is located on top of the outdoor cabinet 2.

[0034] Compared to existing technologies where the outdoor cabinet 2 is positioned in the middle of the pole 1 and a relatively long RF cable is used to connect the outdoor cabinet 2 and the antenna 3, this embodiment features the antenna 3 directly extending from the top of the outdoor cabinet 2, minimizing the length of the RF cable. When the outdoor cabinet 2 is in the middle of the pole 1, the RF cable length is 4-6 meters; with the outdoor cabinet 2 positioned at the top of the pole 1, the RF cable length is reduced to 0.3 meters, reducing cable loss and ensuring equipment performance. This embodiment is primarily used for UAV data transmission. It can be installed and used to fill blind spots along the UAV's fixed route, or it can serve as a UAV relay station to achieve long-distance communication.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, the outdoor cabinet 2 is located on the top side of the support pole 1.

[0036] Antenna 3 is mounted on the top of outdoor cabinet 2 and connected to the RF cable of outdoor cabinet 2 via RF connector 31. RF connector 31 is mounted to outdoor cabinet 2 with screws. Antenna 3, RF connector 31, and the screws used to mount RF connector 31 are waterproofed to withstand various weather conditions.

[0037] like Figure 2 As shown, the support pole 1 is perpendicular to the ground and includes a support pole body 11 and a top seat 12. The support pole body 11 is a cuboid column structure. The top seat 12 is located on the upper part of the support pole 1 and is also a cuboid column structure, with a width greater than the width of the support pole body 11. To ensure the stability of the support pole 1's center of gravity, the solar panel 4 and the outdoor cabinet 2 are positioned opposite each other on the top seat 12. An inspection port 13 is provided at the lower part of the support pole body 11 for maintenance of the support pole 1. The support pole 1 has a hollow structure. To improve the structural strength and balance of the support pole 1, the ratio of the thickness of the support pole 1 to its length is 0.1%-0.3%. Preferably, the ratio of the thickness of the support pole 1 to its length is 0.16%. In this embodiment, the thickness of the support pole 1 is 5mm to ensure that it can bear more than 10 times the combined weight of the outdoor cabinet 2 and the solar panel 4.

[0038] like Figure 3As shown, the outdoor cabinet 2 includes a cabinet body 21 and a door panel 22. Exemplarily, the cabinet body 21 and the door panel 22 are connected by hinges, and a door lock is provided inside to achieve the sealing of the outdoor cabinet 2. A waterproof sealing strip is provided between the door panel 22 and the cabinet body 21 to seal the outdoor cabinet 2, so that the outdoor cabinet 2 has waterproof performance and the equipment is not affected by weather changes.

[0039] The upper side enclosures 211 are symmetrically arranged on both sides of the upper part of the enclosure 21, and the lower side enclosures 212 are symmetrically arranged on both sides of the lower part of the enclosure 21. The upper side enclosures 211 are used for cable access and top protection, and the lower side enclosures 212 are used for the installation of equipment such as the battery 10, as well as cable outlet management and bottom protection.

[0040] Preferably, the bottom of the outdoor cabinet 2 is about 2.3 meters above the ground, a distance that is generally inaccessible to adults, thus preventing the outdoor cabinet 2 from being damaged by human intervention.

[0041] Furthermore, such as Figure 5 As shown, the outdoor cabinet 2 also includes an outdoor cabinet mounting component 23 for mounting the outdoor cabinet 2 to the top mount 12. Exemplarily, the outdoor cabinet mounting component 23 includes a mounting beam, a mounting bracket, and a back panel. The mounting beam is symmetrically arranged laterally on the outside of the outdoor cabinet 2, and the mounting bracket is longitudinally parallel to the mounting beam and detachably connected to the mounting beam by screws or other means. A groove is provided in the middle of the mounting bracket, and the back panel is disposed in the groove. The side of the back panel facing away from the groove is connected to the top mount 12 of the support rod 1.

[0042] Furthermore, the solar panel 4 is tilted and mounted on top of the support pole 1. The data link module 5 can be charged by solar energy, operating 24 hours a day without interruption, achieving energy-saving and consumption-reducing technical effects.

[0043] The solar panel 4 is mounted on the top mount 12 via a bracket 41. The bracket 41 is adjustable, allowing adjustment of the angle between the contact surface of the solar panel 4 and the mounting surface of the bracket 41. By adjusting the bracket 41, the downward angle formed between the back of the solar panel 4 and the mounting surface of the top mount 12 is preferably 45°. Furthermore, the height of the antenna 3 is greater than the height of the solar panel 4, which avoids the solar panel 4 blocking the signal and reduces electromagnetic interference from the solar panel 4 to the antenna 3.

[0044] Outdoor cabinet 2 has a box structure 21, and is equipped with devices such as data link module 5, MPPT controller 6, antenna surge protector 7, low voltage circuit breaker 8 and surge protector 9.

[0045] The data link module 5 is located in the upper part of the outdoor cabinet 2 to shorten the distance to the antenna 3 and reduce cable loss. The antenna surge protector 7 is also located in the upper part of the outdoor cabinet 2; exemplarily, the antenna surge protector 7 is arranged parallel to the data link module 5. One end of the antenna surge protector 7 is connected to the data link module 5, and the other end is connected to the antenna 3 via an RF cable. The antenna surge protector 7 is positioned between the data link module 5 and the antenna 3 for lightning protection, thus protecting the data link module 5.

[0046] The MPPT controller 6, or Maximum Power Point Tracking controller, is a key component of a solar power generation system. Its core function is to maximize the energy conversion efficiency of the solar panel 4 by adjusting the operating voltage and current of the photovoltaic array in real time, ensuring it always operates at its maximum power output point (MPP). The MPPT controller 6 is connected to the solar panel 4 to optimize the voltage and current of the photovoltaic DC input through the MPPT algorithm, and then output power to the battery 10 or directly to the DC load.

[0047] The surge protector 9 and the low-voltage circuit breaker 8 are connected. The surge protector 9 is connected to the MPPT controller 6, and the low-voltage circuit breaker 8 is connected to the data link module 5. The surge protector 9 and the low-voltage circuit breaker 8 are located between the MPPT controller 6 and the data link module 5 to protect the data link module 5.

[0048] The battery 10 is connected to the MPPT controller 6. The battery 10 is used to power the data link module 5 and also stores the electrical energy of the solar cell through the MPPT controller 6.

[0049] The wiring connection in this embodiment is as follows:

[0050] The output of solar panel 4 is connected to the upper side enclosure 211 of outdoor cabinet 2 via a waterproof connector, and then to the solar input port of MPPT controller. The output port of battery 10 of MPPT controller is connected to battery 10 via a cable through lower side enclosure 212. The positive and negative terminals of battery 10 are connected to data link module 5 via MPPT controller, surge protector 9, and low-voltage circuit breaker 8, providing power to data link module 5. When solar power is insufficient, battery 10 discharges to maintain the operation of data link module 5. Antenna 3 is installed on the top of outdoor cabinet 2, and enters the cabinet through RF connector 31 on the top of outdoor cabinet 2. It is connected to the interface of data link module 5 via antenna surge protector 24. Data link module 5 transmits the collected information (such as solar panel voltage and battery 10 charge) to the base station via antenna 3, or receives remote control commands.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
