Description

Technical Field

[0001] This utility model belongs to the field of fresh air equipment technology, specifically relating to a rainproof self-cleaning intelligent fresh air cabinet. Background Technology

[0002] With the rapid development of technologies such as 5G and the Internet of Things, the equipment density and operating load in communication base stations are constantly increasing, making the demand for fresh air cooling systems increasingly urgent. Communication base stations are mostly located in outdoor environments with high levels of pollutants such as dust and willow catkins in the air. Traditional base station fresh air cabinets may not be equipped with self-cleaning functions, requiring frequent manual disassembly and cleaning of filters. This not only results in high maintenance costs but also poses a risk of equipment downtime due to untimely maintenance. In addition, many base station fresh air cabinets are only equipped with simple rainproof grilles. Although these grilles can block some rainwater, during severe weather such as heavy rain or typhoons, rainwater can seep in through the gaps in the grilles or weak points in the cabinet's seal, causing short circuits, component corrosion, and other malfunctions inside the base station.

[0003] Therefore, the fresh air cabinets in outdoor environments need to be designed with self-cleaning and rainproof performance to ensure that the equipment inside the base station is always in a stable and good operating environment. Utility Model Content

[0004] The purpose of this utility model is to provide a rainproof, self-cleaning intelligent fresh air cabinet that overcomes the shortcomings of the prior art. The self-cleaning and rainproof structures of the fresh air cabinet are designed to avoid the problems of rainwater infiltration and filter clogging, ensuring that the equipment in the base station is always in a stable and good operating environment.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A rainproof, self-cleaning intelligent fresh air cabinet includes a cabinet body with an air inlet and an air outlet on both sides. The cabinet body includes a filter chamber and a fresh air chamber. The filter chamber is equipped with a filter assembly, and the fresh air chamber is equipped with a fresh air fan. The airflow generated by the fresh air fan enters the fresh air chamber after passing through the filter assembly.

[0007] The filter assembly includes a grid plate and filter cotton laid on the side of the grid plate near the air inlet. A dust collection component and a drive component are provided on the side of the filter assembly near the air inlet. The dust collection component is equipped with at least one fan for generating airflow to suck up impurities on the surface of the filter cotton. The drive component is used to drive the dust collection component to reciprocate on the surface of the filter cotton.

[0008] Furthermore, the dust collection assembly includes a dust collection chamber extending along the length of the filter cotton, one or more mounting chambers disposed at the bottom of the dust collection chamber, and the bottom of the dust collection chamber is connected to the mounting chamber through a vent. The dust collection chamber has an elongated dust collection port on the side near the filter cotton. A fan is installed in the mounting chamber, and a dust outlet is provided on the side of the mounting chamber away from the filter cotton. The airflow generated by the fan enters through the dust collection port and exits through the dust outlet.

[0009] Furthermore, the drive assembly includes a fixed box located at the bottom of the dust collection chamber, a drive motor installed inside the fixed box, a reel installed on the output shaft of the drive motor, and a steel wire rope wound around the outside of the reel, with the other end of the steel wire rope fixedly connected to the top of the cabinet.

[0010] Furthermore, the filter chamber is provided with a slide rail arranged parallel to the grid plate, and one side of the dust collection component is slidably connected to the slide rail via a roller.

[0013] Furthermore, the grille includes a frame, a fixing plate fixed to one side of the frame, a plurality of evenly distributed vertical grilles fixed within the frame, and horizontal grilles fixed within the frame that intersect the vertical grilles perpendicularly. The end of the horizontal grille near the air inlet is inclined downward, and the fixing plate is detachably connected to the mounting frame.

[0014] Furthermore, a filter screen is installed inside the air inlet, and a rain cover is provided on the outside of the air inlet.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. This utility model uses a drive component to drive a dust collection component to suck up impurities from the surface of the filter cotton and discharge the sucked-up impurities from the cabinet, keeping the surface of the filter cotton clean and achieving a self-cleaning effect, eliminating the need for manual cleaning or replacement of the filter cotton.

[0017] 2. This utility model prevents rainwater from entering the cabinet by using a rain cover, an inclined grille, and an inclined horizontal grille.

[0024] 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.

[0025] like Figures 1-5 As shown, the rainproof self-cleaning intelligent fresh air cabinet of this utility model includes a cabinet body 1, with an air inlet and an air outlet 2 respectively opened on both sides of the cabinet body 1. The cabinet body 1 includes a filter chamber 6 and a fresh air chamber 12. The filter chamber 6 is equipped with a filter component, and the fresh air chamber 12 is equipped with a fresh air fan. The airflow generated by the fresh air fan enters the fresh air chamber 12 after passing through the filter component.

[0026] The filter assembly includes a grid plate 8 and filter cotton 11 laid on the side of the grid plate 8 near the air inlet. A dust collection component 9 and a drive component are provided on the side of the filter assembly near the air inlet. The dust collection component 9 is provided with at least one fan 95 for generating airflow to suck up impurities on the surface of the filter cotton 11. The drive component is used to drive the dust collection component 9 to reciprocate on the surface of the filter cotton 11.

[0027] When the temperature inside the base station rises, the fresh air unit starts and generates airflow that enters the base station through the air inlet, passes through the filter components, and then enters the base station through the air outlet 2, accelerating the air circulation of the base station and thus reducing the temperature inside the base station. After the fresh air unit has been running for a certain period of time or number of times, when the fresh air unit is not running, the dust collection component 9 and the moving component are started. The moving component drives the dust collection component 9 to reciprocate along the surface of the filter cotton 11. At the same time, the dust collection component 9 uses airflow to suck up impurities from the surface of the filter cotton 11 and carries the impurities out of the cabinet through the airflow, keeping the surface of the filter cotton 11 clean, preventing impurities from clogging the air outlet, and maintaining air intake efficiency.

[0028] To facilitate vacuuming, the vacuuming assembly 9 includes a vacuum chamber 91 extending along the length of the filter cotton 11, and one or more mounting chambers 93 located at the bottom of the vacuum chamber 91. The bottom of the vacuum chamber 91 is connected to the mounting chamber 93 via a vent 94. A long, narrow vacuum port 92 is provided on the side of the vacuum chamber 91 closest to the filter cotton 11. A fan 95 is installed inside the mounting chamber 93, and a dust outlet is provided on the side of the mounting chamber 93 furthest from the filter cotton 11. The airflow generated by the fan 95 enters through the vacuum port 92 and exits through the dust outlet. By providing one or more fans 95, airflow is generated to draw air onto the surface of the filter cotton 11, and the airflow carrying impurities is discharged from the dust outlet.

[0029] To facilitate driving the vacuuming assembly 9, the driving assembly includes a fixed box 97 located at the bottom of the vacuuming chamber 91, a drive motor 96 installed in the fixed box 97, a spool installed on the output shaft of the drive motor 96, and a steel wire rope 14 wound around the outside of the spool. The other end of the steel wire rope 14 is fixedly connected to the top of the cabinet 1. A slide rail 10 is provided in the filter chamber 6, which is parallel to the grille plate 8. One side of the vacuuming assembly 9 is slidably connected to the slide rail 10 through a roller.

[0030] When the drive assembly is working, the drive motor 96 is started. The forward or reverse rotation of the drive motor 96 is used to contract or release the steel wire rope 14, so that the vacuuming assembly 9 moves along the slide rail 10 to achieve the effect of reciprocating motion. The design of the roller and the slide rail 10 makes the vacuuming assembly 9 more stable during movement.

[0031] To aid drainage, a mounting port 3 is provided on one side of the cabinet 1. The grille plate 8 is inserted into the cabinet 1 through the mounting port 3, and a fixed rail 7 is provided at the top of the cabinet 1. The top of the grille plate 8 is slidably connected to the fixed rail 7. The top of the grille plate 8 is inclined towards the air inlet. An L-shaped partition 13 is provided inside the cabinet 1. The top of the partition 13 is slidably connected to the grille plate 8, and the other end is connected to the cabinet 1. A drainage gap is provided at the connection between the partition 13 and the cabinet 1. The grille plate 8 includes a frame 81, a fixed plate 82 fixed to one side of the frame 81, multiple evenly distributed vertical grille plates 83 fixed inside the frame 81, and horizontal grille plates 84 fixed inside the frame 81 and perpendicularly intersecting the vertical grille plates 83. The end of the horizontal grille plate 84 near the air inlet is inclined downward. The fixed plate 82 is detachably connected to the mounting frame.

[0032] In the event of extreme weather such as typhoons or heavy rain, rainwater may enter the cabinet 1 through the air inlet. The rainwater will first hit the filter cotton 11 on the surface of the grille plate 8. The rainwater on the filter cotton 11 will flow downward along the direction of the grille plate 8. The inclined grille plate 8 and the horizontal grille plate 84 guide the rainwater to the drainage seam, and then discharge it through the drainage seam, thus preventing rainwater from entering the fresh air chamber 12 and the base station, and protecting the equipment inside the fresh air unit and the base station.

[0033] To improve waterproof performance, a filter 5 is installed inside the air inlet, and a rain cover 4 is installed on the outside of the air inlet. The filter 5 prevents large debris such as stones and branches from entering the cabinet 1. The rain cover 4 improves the rainproof performance of the cabinet 1 and meets the needs of outdoor use.

[0034] In summary, this utility model uses a drive component to drive a dust extraction component 9 to suck up impurities from the surface of the filter cotton 11 and discharge the sucked-up impurities from the cabinet, keeping the surface of the filter cotton 11 clean and achieving a self-cleaning effect without the need for manual cleaning or replacement of the filter cotton 11. At the same time, the rain cover 4, the inclined grille plate 8, and the inclined horizontal grid plate 84 prevent rainwater from entering the cabinet 1. Even if rainwater does enter the cabinet 1, the inclined grille plate 8 and the horizontal grid plate 84 guide the rainwater to drain out from the drainage seam of the cabinet 1, ensuring the normal operation of the equipment inside the base station.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
