Problems solved by technology

[0002] In the existing shunting locomotives, the way of air supply for the air conditioner in the driver's cab is generally to set an air outlet grille on the top of the driver's cab to directly connect with the air outlet of the air conditioner. The wind speed on the driver's head is too high, which will affect the comfort of the driver's air conditioner

Embodiment 1

[0026] A distributed air-supply air duct structure for the cab of a shunting locomotive, such as Figure 1-3 As shown, it includes the upper left air duct 1 and the upper right air duct 2 placed on the top of the driver's cab, the upper left air duct 1 is provided with a butt hole 5 for the air outlet of the air conditioner, and the upper left air duct 1 and the upper left air duct 3 connected; the upper right air duct 2 is provided with a butt hole 6 of the air outlet of the air conditioner, and the upper right air duct 2 communicates with the right air duct 4; the bottom of the left air duct 3 and the bottom of the right air duct 4 are provided with A number of air outlets, the inside of the left air duct 3 and the inside of the right air duct 4 are provided with a static pressure partition chamber 9, one of the static pressure partition chambers 9 is arranged at 1-4 of the air outlets, and several of the air outlets There are several adjustable outlet grilles 7 placed at th...

Embodiment 2

[0028] Based on the above-mentioned embodiment 1, such as figure 2 As shown, the bottom of the left air duct 3 and the bottom of the right air duct 4 are also provided with no less than two non-adjustable air outlet grilles 8 . In this embodiment, there are not less than two non-adjustable air outlet grilles 8 at the bottom of the left air duct 3 and the bottom of the right air duct 4 respectively, which can prevent the air conditioner from freezing and cause the air conditioner to shut down. This is because The air conditioner itself has a pressure alarm. After the evaporator tube freezes, the pressure inside the tube increases, and the alarm will shut down the air conditioner to protect the air conditioner. Therefore, if the air outlet grille is completely closed, the air circulation will be blocked, and the heat will not be exchanged. It will freeze, causing the air conditioner to be shut down for protection. Therefore, it is necessary to set the non-adjustable air outlet ...

Embodiment 3

[0030] Based on the above-mentioned embodiment 2, such as figure 2 As shown, the non-adjustable air grid 8 at the bottom of the left air duct 3 is set away from the upper left air duct 1 end, and the non-adjustable air grid 8 at the bottom of the right air duct 4 is far away from the upper right air duct 2 end. In this embodiment, the non-adjustable air grid 8 set on the left air duct 3 is kept away from the upper left air duct 1, and the non-adjustable air grid 8 set on the right air duct 4 is kept away from the upper right air duct 2, because the non-adjustable wind When the grid is away from the upper left air channel 1 and the upper right air channel 2, it is far away from the operator's seat console in the driver's cab, thereby ensuring that all the air outlet grids on the driver's seat are adjustable air grids 7.

The invention provides a distributed air supply duct structure, so a driver's comfort is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of locomotives, and in particular relates to a distributed air supply duct structure for an air conditioner in a cab of a shunting locomotive. Background technique [0002] In the existing shunting locomotives, the way of air supply for the air conditioner in the driver's cab is generally to set an air outlet grille on the top of the driver's cab to directly connect with the air outlet of the air conditioner. The wind speed on the driver's head is too high, etc., which will affect the comfort of the driver's air conditioner. Contents of the invention [0003] The technical problem solved by the invention is to provide a distributed air supply duct structure, thereby effectively improving the driver's comfort. [0004] The technical scheme that the present invention adopts is as follows: [0005] A distributed air supply duct structure for air conditioners in shunting locomotive cabs, including an upper l...
