Description

Technical Field

[0001] This utility model relates to the field of outdoor communication unit technology, specifically a low-power outdoor communication unit resistant to harsh environments. Background Technology

[0002] Outdoor communication units, as key infrastructure in modern communication networks, play a pivotal role in energy, transportation, national defense, and emergency rescue. Their technological essence has evolved from a single communication function to a comprehensive system integrating efficient energy management, environmental adaptability, and intelligent operation and maintenance. Facing the global digitalization and the widespread adoption of 5G and the Internet of Things, outdoor units must operate stably in harsh environments such as uninhabited areas, high mountains, deserts, and open seas, coping with multiple challenges including extreme temperatures, strong winds and dust storms, high humidity and salt spray, and limited energy resources.

[0003] Traditional outdoor communication cabinets often employ a design with built-in cooling fans and ventilation louvers. For example, the utility model patent CN205596478U discloses a "waterproof and moisture-proof outdoor communication cabinet," which attempts to balance heat dissipation and moisture protection by introducing dry air through ventilation openings, rain shields, and air distribution pipes inside the cabinet. However, while the ventilation openings can introduce external air for convection cooling, they also provide a path for dust and moisture to intrude. The dust filter requires maintenance and cannot completely prevent the penetration of fine water mist. The built-in fan cooling method essentially introduces unfiltered humid air directly into the cabinet. Although it is dried, its effectiveness is reduced in long-term high-humidity environments and may lead to condensation on internal components. Furthermore, waterproofing at the cabinet joints relies heavily on physical sealing strips, whose sealing performance deteriorates after long-term thermal expansion and contraction and aging, making it difficult to dynamically adapt to extreme conditions such as wind and rain. Therefore, we propose a low-power outdoor communication unit that is resistant to harsh environments. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a low-power outdoor communication unit resistant to harsh environments, comprising a unit housing, a side mounting box fixedly installed on the left side of the unit housing, a heat dissipation chamber fixedly installed on the rear side of the unit housing, a dustproof heat dissipation mechanism provided inside the heat dissipation chamber, the dustproof heat dissipation mechanism including a mounting plate embedded between the heat dissipation chamber and the unit housing, multiple integrated frames fixedly installed on the mounting plate, the integrated frames penetrating the mounting plate and having corresponding heat dissipation fins fixedly installed on the back of the mounting plate, an axial flow fan fixedly installed on the heat dissipation chamber, and a dustproof net and a rainproof cover embedded above the axial flow fan, a dustproof cover rotatably installed on the heat dissipation chamber, and an installation groove provided inside the unit housing, with an airbag ring embedded in the installation groove.

[0005] In some embodiments, a toothed ring is fitted onto the dust cover, a drive wheel is rotatably installed inside the heat dissipation chamber, the drive wheel is meshed with the toothed ring, a scraper is provided on the unit box, the scraper is fitted to the surface of the dust cover, a first rack is slidably installed inside the unit box, and a cylinder is fixedly installed inside the unit box.

[0006] In some embodiments, the scraper is rotatably connected to the unit housing via a mounting shaft, a first gear is sleeved on the mounting shaft, the first rack is meshed with the first gear, and the first rack is fixedly connected to the output end of the cylinder piston rod.

[0007] In some embodiments, a scraper is rotatably mounted on the heat dissipation chamber, the scraper being fitted with a scraper brush, a second gear being sleeved on the scraper, a second rack being slidably mounted inside the heat dissipation chamber, the second rack being meshed with the second gear, a connecting rod being rotatably mounted on the second rack, a crank being rotatably mounted inside the heat dissipation chamber, the crank being rotatably connected to the end of the connecting rod away from the second rack via a rotating shaft, a slide rod being fixedly mounted inside the heat dissipation chamber, the second rack being slidably sleeved with the slide rod, and two sets of symmetrically distributed springs being sleeved on the slide rod, the two ends of the two sets of springs being fixedly connected to the second rack and the heat dissipation chamber, respectively.

[0008] In some embodiments, a door is rotatably mounted on the unit box, the airbag ring is correspondingly provided with the door and the seam of the unit box, a miniature electric air pump is fixedly installed in the side mounting box, a venting solenoid valve is fixedly installed in the side mounting box, a control module is fixedly installed in the side mounting box, and a rain sensor and a wind speed sensor are fixedly installed on the top of the unit box.

[0009] In some embodiments, the outlet of the micro electric air pump is connected to the airbag ring through an inflation pipe, the signal output terminals of the rain sensor and the wind speed sensor are electrically connected to the signal input terminal of the control module, one end of the venting solenoid valve is connected to the airbag ring through a venting pipe, and the other end is open to the atmosphere, and the control terminal of the venting solenoid valve is electrically connected to the control module.

[0010] In some embodiments, a photovoltaic module is fixedly installed on the unit box via a connector, and a photovoltaic controller and a battery pack are fixedly installed inside the side-mounted box. The power output terminal of the photovoltaic module is connected to the photovoltaic input terminal of the photovoltaic controller via a cable, and the battery terminal of the photovoltaic controller is electrically connected to the battery pack.

[0011] This utility model has at least the following beneficial effects: 1. By integrating the frame and heat sink fins, the heat from the core heat-generating components is directly transferred to an independent heat dissipation chamber, where forced convection cooling is achieved by an axial fan. This design enables precise and efficient heat dissipation for components with high heat flux density. Simultaneously, the heat dissipation duct is physically isolated from the main equipment compartment, completely eliminating the risk of external dust and moisture entering the equipment through the heat dissipation channel. This fundamentally solves the technical problem of the contradiction between heat dissipation and protection in traditional designs. Furthermore, a cylinder drives the first rack and gear, which in turn drives a scraper to reciprocate and wipe the surface of the dust cover, effectively removing dust, catkins, and other debris, ensuring long-term unobstructed airflow at the heat dissipation inlet. The crank, connecting rod, second rack, and spring mechanism drive the scraper to simultaneously clean itself, forming a closed-loop self-cleaning system. This greatly reduces maintenance requirements and ensures the long-term high efficiency and stability of the heat dissipation system in dusty environments.

[0012] 2. By incorporating an airbag ring at the joint between the door and the enclosure, along with rain and wind speed sensors and a control module, dynamic intelligent management of the sealing status is achieved. When severe weather conditions such as wind and rain are detected, the control module activates a micro electric air pump to inflate the airbag ring, forming a high-pressure, tight seal that effectively prevents the penetration of rainwater and moisture. When the weather improves, the venting solenoid valve is opened to release air, preventing long-term pressure fatigue of the seals, improving the equipment's protection capabilities in extreme weather conditions, and extending the service life of the seals. Photovoltaic modules are installed through connectors, and solar energy is stored in the battery pack via the photovoltaic controller, providing continuous low-power green energy for the unit, especially the heat dissipation and sealing systems, effectively extending the equipment's continuous operating time in environments without mains power supply.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a low-power outdoor communication unit resistant to harsh environments, including a unit housing 1, a side mounting box 2 fixedly installed on the left side of the unit housing 1, and a heat dissipation chamber 3 fixedly installed on the rear side of the unit housing 1. The heat dissipation chamber 3 is equipped with a dustproof and heat dissipation mechanism 4, which includes a mounting plate 401 embedded between the heat dissipation chamber 3 and the unit housing. Multiple integrated frames 402 are fixedly installed on the mounting plate 401, with each integrated frame 402 penetrating the mounting plate 401 and having corresponding heat dissipation fins 403 fixedly installed on the back of the mounting plate 401. An axial flow fan 404 is fixedly installed on the heat dissipation chamber 3, and a dustproof net and rainproof cover are embedded above the axial flow fan 404. The unit is equipped with a dust cover 405. An installation slot 8 is provided inside the unit housing 1, and an airbag ring 9 is embedded in the installation slot 8. The main heat-generating components inside the unit are fixedly installed on the integrated frame 402. The heat generated by the components is directly conducted to the heat dissipation fins 403 located in the heat dissipation chamber 3 through the integrated frame 402. After the axial flow fan 404 is started, the hot air in the heat dissipation chamber 3 is extracted, forcing the cold air to enter from the dust cover 405 and flow through the heat dissipation fins 403 to cool it. This forms an independent air duct for dissipating heat from the heat-generating components, completely isolating the heat dissipation air duct from the main equipment compartment, ensuring that dust and moisture only exist in the heat dissipation chamber 3 and cannot penetrate the interior of the unit housing 1 where precision electronic components are placed.

[0017] A gear ring 406 is fitted onto the dust cover 405. A drive wheel 407 is rotatably mounted inside the heat dissipation chamber 3, and the drive wheel 407 meshes with the gear ring 406. A scraper 408 is provided on the unit housing 1, and the scraper 408 is fitted against the surface of the dust cover 405. A first rack 411 is slidably mounted inside the unit housing 1, and a cylinder 412 is fixedly mounted inside the unit housing 1. The scraper 408 is rotatably connected to the unit housing 1 via a mounting shaft 409, on which a first gear 410 is fitted. The first rack 411 meshes with the first gear 410. The first rack 411 is fixedly connected to the output end of the piston rod of the cylinder 412. During use, the motor on the heat dissipation chamber 3 can be turned on to drive the drive wheel 407 to rotate, which, together with the gear ring 406, achieves uniform rotation of the dust cover 405. During the uniform rotation of the dust cover 405, it scrapes against the scraper 408 that is in contact with it, thus cleaning the impurities on the surface of the dust cover 405. When the scraper 408 needs cleaning, the piston rod of the cylinder 412 is activated to extend or retract, driving the first rack 411 fixed thereto to make linear motion. The first rack 411 then drives the first gear 410 that meshes with it to rotate, and finally, through the mounting shaft 409, the scraper 408 completes the conversion of its two working ends, preventing impurities that have adhered to one end of the scraper 408 after a period of use from re-adhering to the dust cover 405.

[0018] A scraper 413 is rotatably mounted on the heat dissipation chamber 3, and the scraper 413 is fitted into the scraper brush 408. A second gear 414 is sleeved on the scraper 413. A second rack 415 is slidably mounted inside the heat dissipation chamber 3, and the second rack 415 is meshed with the second gear 414. A connecting rod 418 is rotatably mounted on the second rack 415. A crank 419 is rotatably mounted inside the heat dissipation chamber 3. The crank 419 is rotatably connected to the end of the connecting rod 418 away from the second rack 415 via a rotating shaft. A slide rod 416 is fixedly mounted inside the heat dissipation chamber 3. The second rack 415 is slidably sleeved with the slide rod 416. Two sets of symmetrically distributed springs 417 are sleeved on the slide rod 416. The two ends of the two sets of springs 417 are fixedly connected to the second rack 415 and the heat dissipation chamber 3, respectively. After the scraper 408 turns its working end, the end with the adhering impurities corresponds to the scraper 413. The motor inside the heat dissipation chamber 3 drives the crank 419 to rotate. The rotational motion of the crank 419 is converted into the reciprocating linear motion of the second rack 415 on the slide rod 416 through the connecting rod 418. The reciprocating motion of the second rack 415 drives the second gear 414 meshing with it to rotate forward and backward, thereby causing the scraper 413 to swing. Since the scraper 413 is fitted to the bristles of the brush 408, the swing of the scraper 413 can remove the dust that is swept off the brush 408, preventing it from accumulating and affecting the cleaning effect. The function of the spring 417 is to provide a reset buffer for the second rack 415 and to keep it tightly engaged.

[0019] Example 2: Please see Figure 5The unit box 1 is rotatably mounted with a door. The airbag ring 9 is correspondingly set at the joint between the door and the unit box 1. A miniature electric air pump 10 is fixedly installed inside the side mounting box 2. A venting solenoid valve 11 is fixedly installed inside the side mounting box 2. A control module 14 is fixedly installed inside the side mounting box 2. A rain sensor 12 and a wind speed sensor 13 are fixedly installed on the top of the unit box 1.

[0020] The outlet of the miniature electric air pump 10 is connected to the airbag ring 9 via an inflation pipe. Its power input is electrically connected to the control module 14 inside the outdoor communication unit box 1. Its function is to start according to the command issued by the control module 14 and provide the gas required for the inflation of the airbag ring 9. The signal output terminals of the rain sensor 12 and the wind speed sensor 13 are electrically connected to the signal input terminal of the control module 14. Their function is to monitor the rainfall and wind speed signals in the external environment of the box in real time and transmit the monitored signal data to the control module 14. The control module 14 has a preset wind and rain judgment logic, which receives and processes the data. When the signal data from the wind and rain sensor group simultaneously meets the conditions of "rain detected" and "wind speed value higher than the set threshold", it is determined to be windy and rainy weather. Then, a start signal is sent to the micro electric air pump 10. One end of the venting solenoid valve 11 is connected to the airbag ring 9 through a venting pipe, and the other end is open to the atmosphere. The control end of the venting solenoid valve 11 is electrically connected to the control module 14. Its function is to open according to the instruction of the control module 14 after the rain sensor 12 and the wind speed sensor 13 detect that the windy and rainy weather has ended and has lasted for a period of time, so as to release the gas in the airbag ring 9 and restore it to its original state.

[0021] A photovoltaic module 5 is fixedly installed on the unit housing 1 via connectors. A photovoltaic controller 6 and a battery pack 7 are fixedly installed inside the side-mounted housing 2. The power output terminal of the photovoltaic module 5 is connected to the photovoltaic input terminal of the photovoltaic controller 6 via a cable. The battery terminal of the photovoltaic controller 6 is electrically connected to the battery pack 7. The photovoltaic module 5 converts solar energy into electrical energy, which is then transmitted to the photovoltaic controller 6 via the cable. The photovoltaic controller 6 performs voltage stabilization, rectification, and other optimization processes on the electrical energy. On the one hand, it directly supplies power to the unit's heat dissipation and sealing systems. On the other hand, it stores excess electrical energy in the battery pack 7. At night or in the absence of sunlight, the battery pack 7 releases electrical energy to continue providing power to the equipment, greatly extending the continuous working time of the equipment in environments without mains power, and achieving the goals of low power consumption and high self-sufficiency.
