Description

Technical Field

[0001] This utility model relates to the field of aircraft ground air conditioning technology, and in particular to a drainage structure for aircraft ground air conditioning. Background Technology

[0002] When an aircraft is parked on the ground, its own air conditioning system alone may not be able to effectively maintain a suitable temperature and humidity in the cabin. Aircraft ground air conditioning can provide conditioned fresh air to the aircraft cabin and cockpit, and regulate the air temperature and humidity, so that passengers and crew members are in a comfortable environment during boarding, disembarking and waiting.

[0003] Aircraft ground air conditioning systems cool and dehumidify the air during operation. When hot, humid air passes through the air conditioner's heat exchanger, water vapor in the air condenses into liquid water upon cooling. This condensate needs to be drained promptly to ensure the normal operation of the air conditioning system. If the condensate is discharged directly to the ground, it may accumulate in areas such as airport runways, taxiways, and aprons, affecting aircraft taxiing and the safety of ground vehicles, and may even damage airport facilities. Therefore, it is necessary to use water collection boxes to collect the condensate for subsequent centralized treatment and discharge.

[0004] During air conditioning operation, dust and impurities in the air may enter the water storage box along with the condensate and gradually accumulate in the water storage box or drain pipe, eventually causing the water storage box to become clogged. The water storage box may even experience corrosion, wear, or aging of seals due to long-term contact with condensate. Therefore, it is necessary to open the water storage box regularly for maintenance and clean these impurities in a timely manner. However, the water storage box is usually located independently at the bottom of the aircraft ground air conditioning unit, making it difficult for staff to reach the water storage box and thus inconvenient to clean and maintain the inside of the water storage box.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a drainage structure for aircraft ground air conditioning, which aims to solve the technical problem of inconvenience in cleaning and maintaining the inside of the water storage box.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A drainage structure for an aircraft ground air conditioner includes a base plate of the air conditioning unit and a water storage box disposed on the base plate. The water storage box includes a box body with an upper opening and a cover plate that can be detached and sealed. An inspection port adapted to the shape of the cover plate is provided on the base plate. The box body is fixed to the bottom of the base plate. After the cover plate is inserted into the inspection port, the cover plate and the base plate are spliced ​​together, and the cover plate and the base plate together serve as a passageway support surface. A water inlet pipe and a drain pipe are connected to the side of the box body.

[0009] As a further improvement to the above technical solution, the edge of the cover plate is folded upward to form a flange that matches the inner wall of the inspection port.

[0010] As a further improvement to the above technical solution, threaded holes are provided on the upper surface of the box body, and through holes with the same number as the threaded holes are provided on the cover plate. The detachable bolts pass through the through holes and are connected to the corresponding threaded holes.

[0011] As a further improvement to the above technical solution, corner strips are welded to the side of the box body, and the corner strips fix the box body to the bottom surface of the base plate by fixing bolts.

[0012] As a further improvement to the above technical solution, a sealing ring is provided between the box body and the cover plate.

[0013] As a further improvement to the above technical solution, a drainage control valve is provided on the drainage pipe.

[0014] As a further improvement to the above technical solution, the water storage box is square-shaped.

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, the drainage structure provided by this utility model uses the cover plate and the bottom plate of the water storage box to serve as a support surface for the passageway. This not only does not affect the normal use of the space under the air conditioning unit, but also allows the water storage box to be easily opened by removing the cover plate, so as to clean and maintain the water storage chamber of the water storage box. This solves the problem of inconvenient cleaning and maintenance of the water storage box in the prior art. Attached Figure Description

Detailed Implementation

[0021] This utility model provides a drainage structure for an aircraft ground air conditioner. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0022] Please see Figures 1 to 4 This utility model provides a drainage structure for an aircraft ground air conditioner, including a base plate 1 of the air conditioning unit and a water storage box 2 disposed on the base plate 1. The water storage box 2 includes a box body 21 with an upper opening and a cover plate 22 that can be detached and sealed to the box body 21. An inspection port 1 is provided on the base plate 1, which is adapted to the shape of the cover plate 22. The box body 21 is fixed to the bottom of the base plate 1. After the cover plate 22 is inserted into the inspection port 11, the cover plate 22 is spliced ​​with the base plate 1. The cover plate 22 and the base plate 1 together serve as a passageway support surface. A water inlet pipe 3 and a drain pipe 4 are connected to the side of the box body 21.

[0023] During aircraft ground air conditioning operation, condensate generated from the cooling and dehumidification of hot and humid air by the heat exchanger flows into the water storage box 2 through the water inlet pipe 3, where the water storage box 2 collects the condensate. Under normal circumstances, the cover plate 22, after being embedded in the inspection port 11, is spliced ​​with the base plate 1 to serve as a passageway support surface. This passageway support surface can be understood as providing support for workers to step on when walking inside the air conditioning unit, without affecting the normal use of the space at the bottom of the air conditioning unit. When it is necessary to open the water storage box 2 for maintenance and cleaning, workers stand on the base plate 1 inside the unit and then remove the cover plate 22 to easily open the water storage box 2 and clean and maintain the water storage chamber 20 of the water storage box 2. This solves the problem of inconvenient cleaning and maintenance of the water storage box 2 in the existing technology, effectively avoiding blockage of the water storage box 2 due to the accumulation of dust and impurities, as well as corrosion, wear, and aging of seals caused by long-term contact with condensate. This ensures the normal operation and maintenance convenience of the aircraft ground air conditioning drainage structure and improves the overall reliability and practicality of the aircraft ground air conditioning.

[0024] It should be noted that the bottom of the aircraft ground air conditioning unit is equipped with a support beam 6 to support the entire unit. Therefore, the base plate 1 of the aircraft ground air conditioning unit is not in direct contact with the unit placement surface. A space is formed between the base plate 1 and the unit placement surface for the water storage box 2 and related pipes to be arranged.

[0025] See Figure 4 As shown, the edge of the cover plate 22 is folded upward to form a flange 221 that matches the inner wall of the access port 11. The flange 221 formed by the upward folding of the edge of the cover plate 22 and the inner wall of the access port 11 can enhance the tightness of the connection between the cover plate 22 and the access port 11, improve the sealing effect, and effectively prevent condensate from seeping out from the gap between the cover plate 22 and the access port 11, avoiding adverse effects on the surrounding environment of the air conditioning unit. On the other hand, this flange 221 structure makes the cover plate 22 more stable after being embedded in the access port 11, and it is not easy to shift or shake. When used as a passageway support surface, it can provide more reliable support, ensuring the safety and stability of personnel walking or working on it. This further improves the reliability and practicality of the aircraft ground air conditioning drainage structure during use and reduces the safety hazards and failure risks that may be caused by structural instability.

[0026] For details, see Figure 3 and Figure 4 As shown, threaded holes are formed on the upper surface of the housing 21, and through holes 222, which are the same number as the threaded holes and correspond one-to-one, are formed on the cover plate 22. Removable bolts 23 pass through the through holes 222 and connect to the corresponding threaded holes, achieving a reliable detachable connection between the cover plate 22 and the housing 21. When cleaning and maintenance of the water storage box 2 is required, the removable bolts 23 can be loosened, allowing staff to easily and quickly remove the cover plate 22. This simple and efficient operation greatly improves the convenience and efficiency of maintenance work. Simultaneously, this threaded connection ensures that the cover plate 22 and the housing 21 are tightly connected during normal air conditioning operation, maintaining good sealing performance and effectively preventing condensate leakage and the entry of external dust and impurities into the water storage box 2. This ensures that the water storage box 2 can stably collect and store condensate, guaranteeing the normal operation of the aircraft ground air conditioning drainage system, reducing the probability of malfunctions caused by poor sealing or unreliable connections, and thus improving the overall reliability and stability of the aircraft ground air conditioning system.

[0027] Further details can be found here. Figure 3As shown, corner strips 24 are welded to the side of the box 21, and the corner strips 24 fix the box 21 to the bottom surface of the base plate 1 by fixing bolts 25. This fixing method significantly enhances the firmness and stability of the connection between the box 21 and the base plate 1. During the operation of the aircraft ground air conditioning, even under the influence of aircraft movement, vibration, and various forces generated by the operation of the air conditioning itself, the box 21 can be firmly installed on the base plate 1, avoiding displacement, tilting, or even falling off due to loose connections, thereby ensuring the continuous and normal functioning of the water storage box 2 in collecting condensate. At the same time, the firm connection structure also helps to reduce noise that may be generated by the shaking of the box 21, optimizing the air conditioning operating environment. Moreover, during maintenance operations, the stable position of the box 21 makes it easier for staff to perform related operations, such as disassembling connecting pipes, further improving the overall reliability, practicality, and ease of maintenance of the aircraft ground air conditioning drainage structure.

[0028] Further details can be found here. Figure 3 and Figure 4 As shown, a sealing ring 26 is provided between the housing 21 and the cover plate 22. The sealing ring 26 can prevent condensate from leaking from the connection between the housing 21 and the cover plate 22, avoiding damage to the electrical components and wiring inside the air conditioning unit due to water leakage, and ensuring the electrical safety and stability of the air conditioning unit. At the same time, a good seal can also prevent external dust, impurities and other foreign objects from entering the water storage box 2, reducing the risk of blockage or corrosion caused by the accumulation of impurities inside the water storage box 2, and extending the service life of the water storage box 2 and the entire drainage structure.

[0029] Preferred, see Figure 2 As shown, the drain pipe 4 is equipped with a drain control valve 5, which can precisely control the timing and amount of condensate discharge from the water storage box 2. During the operation of the aircraft ground air conditioning, the drainage flow rate can be flexibly adjusted according to actual needs. For example, when the humidity is high and the amount of condensate produced is large, the drainage flow rate can be appropriately increased. When the operating status of the air conditioning system changes or special control of drainage is required, the drainage speed can be paused or controlled by closing or adjusting the drain control valve 5 to avoid adverse effects on the drainage system and the surrounding environment due to excessively fast or slow drainage. This helps maintain the pressure stability of the entire drainage system, prevents problems such as pipe blockage and backflow caused by abnormal drainage, improves the reliability and stability of the drainage system, and also facilitates centralized management and monitoring of condensate discharge. This allows staff to accurately control and maintain the air conditioning drainage, ensuring the normal operation of the aircraft ground air conditioning and the safety and normal use of airport ground facilities.

[0030] In this embodiment, the water storage box 2 is square-shaped. From a space utilization perspective, the regular square-shaped structure can more efficiently adapt to the space layout at the bottom of the aircraft ground air conditioning unit, reducing space waste and facilitating installation and layout planning within a limited space, thus improving the overall compactness of the air conditioning unit structure. In terms of manufacturing, the square shape is relatively simple and easy to manufacture using standardized production processes and molds, which can effectively reduce production costs and production cycles, and improve production efficiency. Of course, in other embodiments, the water storage box 2 can be round.

[0031] In fact, see Figure 3 As shown, the side of the water storage box 21 is provided with a through-hole protective clip 7, which is connected to the water inlet pipe 3 and the drain pipe 4.
