Description

Technical Field

[0001] This utility model belongs to the field of inspection and maintenance technology, specifically relating to a filter device for the condensate drain outlet of an air conditioner in a high-speed train. Background Technology

[0002] Currently, the design of intercity EMUs did not take into account the need for cleaning of air conditioning condensate drain outlets during routine maintenance. This has resulted in an unreasonable design of the air conditioning condensate drain outlet location, making it impossible to effectively unclog during routine cleaning. As a result, condensate often flows back into the carriage due to blockage of the air conditioning condensate drain outlet by foreign objects, which seriously affects the quality of passenger service.

[0003] Currently, there is a lack of a filter device for the condensate drain outlet of the air conditioning system in high-speed trains to protect the condensate drain outlet and ensure smooth drainage.

[0004] Therefore, a new technology is needed to address the lack of a filter device for the condensate drain outlet of the air conditioning system in high-speed trains. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a filter device for the condensate drain outlet of a high-speed train's air conditioning system, which can protect the condensate drain outlet and ensure smooth drainage of the air conditioning condensate drain outlet of the high-speed train.

[0006] The present invention adopts the following technical solution:

[0007] A filter device for the condensate drain outlet of an air conditioner in a high-speed train includes a filter body and a cover; a first water inlet groove is provided on one side of the filter body; a second water inlet groove is provided on the bottom surface of the filter body; the first water inlet groove and the second water inlet groove are connected; the cover is disposed on the filter body; the filter body can be disposed on an air conditioner drip tray for drainage protection.

[0008] Furthermore, the filter body has a box structure.

[0009] Furthermore, the filter body has an inner cavity; the first water inlet tank and the second water inlet tank are respectively connected to the inner cavity.

[0010] Furthermore, one side of the filter body is provided with a plurality of first water inlet grooves; the plurality of first water inlet grooves constitute a grid water inlet groove.

[0011] Furthermore, a barrier net is provided at the water inlet of the grille.

[0012] Furthermore, the second water inlet tank includes a bent water inlet tank and a square water inlet tank; one end of the bent water inlet tank is connected to a first water inlet tank, and the other end is connected to the square water inlet tank.

[0013] Furthermore, the cover is flip-up and mounted on the filter body.

[0014] Furthermore, the bottom panel of the filter body is provided with fixing holes for fixing the position.

[0015] Furthermore, the filter device also includes fasteners; the fasteners can pass through the fixing holes to fix the filter body to the air conditioner drip tray.

[0016] Furthermore, the filter body is a nickel-plated carbon steel filter body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] A filter device for the condensate drain outlet of an air conditioner in a high-speed train has a filter body that can be installed on the air conditioner's water collection tray. Once installed, the first water inlet tank connects to the air conditioner's drain channel, and the second water inlet tank connects to the drain outlet at the drain channel. Thus, water discharged from the air conditioner can smoothly drain through the "drain channel → first water inlet tank → second water inlet tank → drain outlet at the drain channel." A cover is placed on the filter body, allowing maintenance personnel to quickly open it for cleaning the inside of the filter body during maintenance, effectively preventing clogging.

[0019] This utility model of filter device can protect the air conditioning condensate drain outlet, ensuring smooth drainage of the air conditioning condensate drain outlet of the EMU train, and effectively solving the problem of water entering the carriage due to blockage of the air conditioning condensate drain outlet.
