Abstract
The utility model relates to a low noise ventilation window for vehicle carried power plant, which comprises a through window on the side wall of the carriage of the vehicle carried power plant and a window page positioned on the window which can open or close the window. The utility model is characterized in that: the carriage inside of the window is fixedly provided with a sound-absorbing baffle whose size is bigger or equal with the window and has a proper distance with the window. The space between the sound-absorbing baffle and the carriage cavity are communicated with each other. The utility model makes noise send out through the window greatly reduced of the vehicle carried power plant, and the utility model has enough air convection quantity and can hold fully cooling in the running procedure of the generating set.
Description
Affiliated technical field
The utility model relates to a kind of ventilation window that advances of local structure, the particularly low-noise vehicle-mounted power station that is arranged on the vehicle-mounted power station of mainly being made up of the fuel electric generator group on the automobile bodies.
Background technology
Vehicle-mounted power station is as the vehicular power generation station, is used in specially can't repair or not have the place of power supply for the moment as unexpected power failure and be badly in need of emergent occasion such as electricity consumption.The structure of at present existing vehicle-mounted power station all is that transport vehicle is as Move tool, the fuel electric generator group that is used to generate electricity then is arranged in the compartment of vehicle, in order to make that generator set can normal operation, the ventilation window that advances that air can convection current to be set on the envelope in compartment generally.But the noise that the generator set working process produces also directly is sent to the outside, compartment by the ventilation window that advances on the compartment, the environment around the ear-piercing people's of disturbing noise can have influence on naturally.When vehicle-mounted power station was in the operation of densely populated community, the noise of the decibel value that exceeds standard was given people's life, work, study and physically and mentally healthyly but can be caused certain infringement.
Summary of the invention
In order to overcome the problem that ventilation window directly transmits noise of advancing of existing vehicle-mounted power station, the utility model provides a kind of ventilation window that advances of improved low-noise vehicle-mounted power station, can reduce the noise of vehicle-mounted power station unofficial biography effectively.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of low-noise vehicle-mounted power station advance ventilation window, comprise the outer logical window on the railroad car lateral wall of vehicle-mounted power station and be installed in the window page or leaf that can open or close window on the window, it is characterized in that: inboard place, the compartment of window is fixed with the sound-absorbing baffle plate, the sound-absorbing plate washer more than or equal to the size of window and and window between suitable distance is arranged, the sound-absorbing baffle plate communicates with the compartment inner chamber with pitch space between the window.
The above-mentioned window page or leaf that can open or close window that is installed on the window can be to be hinged on the compartment wall at window place on one side, and another side is realized opening or closing of window page or leaf by strut member; Also can be that the window page or leaf is slidingly fitted in the modes such as track on the compartment wall at window place.Fixing of the inboard, compartment of above-mentioned sound-absorbing baffle plate and window, should make suitable distance is arranged between sound-absorbing baffle plate and the window, the sound-absorbing baffle plate is communicated with the compartment inner chamber with pitch space between the window, and its fixed form can be by a part of edge and the compartment wall that is connected the sound-absorbing baffle plate with the plate body or the rod member of compartment wall approximate vertical.Above-mentioned window can also be provided with other suitable structure, as rodent-proof mesh etc.
The beneficial effects of the utility model are: because inboard place, the compartment of window is fixed with the sound-absorbing baffle plate, the sound-absorbing baffle plate has suitable distance more than or equal to the size of window and with window, so the noise in the compartment is subjected to effectively stopping of sound-absorbing baffle plate and absorbs, the noisiness that spreads out of window is reduced greatly; Because the sound-absorbing baffle plate communicates with the compartment inner chamber with pitch space between the window, so the sound-absorbing baffle plate does not hinder the generator set operational process to obtain enough circulating air amounts and dispels the heat fully.Protect ambient environment not to be subjected to the infringement of vehicle-mounted power station so effectively, guaranteed people's normal life and physical and mental health.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the local structure scheme drawing of an embodiment of the utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among the figure: 1, body side wall; 2, window; 3, window page or leaf; 4, sound-absorbing baffle plate; 5, pitch space; 6, compartment inner chamber; 7, strut member; 8, rodent-proof mesh.
The specific embodiment
With reference to accompanying drawing, this low-noise vehicle-mounted power station advance ventilation window, comprise the outer logical window (2) on the railroad car lateral wall (1) of vehicle-mounted power station and be installed in the window page or leaf (3) that can open or close window (2) on the window (2), the inboard place, compartment that it is characterized in that window (2) is fixed with sound-absorbing baffle plate (4), sound-absorbing baffle plate (4) more than or equal to the size of window (2) and and window (2) between suitable distance is arranged, sound-absorbing baffle plate (4) communicates with compartment inner chamber (6) with pitch space (5) between the window (2).In addition, the described window page or leaf (5) that can open or close window that is installed on the window (2), be that the top is hinged on the railroad car lateral wall (1) of window (2) top, strut member (7) one ends of a hydraulically extensible are articulated in window (2) side, and its other end is articulated in window page or leaf (5) inboard.When the fuel electric generator group is started working, by strut member (7) window page or leaf (5) is opened, guarantee the ventilation and the heat radiation of generator set.One deck corrosion-resistant steel rodent-proof mesh (8) is installed on the window of compartment madial wall, damages generator set in the compartment to prevent that harmful toys such as muroid from entering.Like this fuel electric generator group when work the noise that produces, after at first being cut down by sound-absorbing baffle plate (4) and absorbing, when advancing ventilation window and be delivered to outside the compartment, noise weakens widely to the interference of ambient environment, and has obtained effective control.
Claims (2)
1, a kind of low-noise vehicle-mounted power station advances ventilation window, comprise the outer logical window on the railroad car lateral wall of vehicle-mounted power station and be installed in the window page or leaf that can open or close window on the window, it is characterized in that: inboard place, the compartment of window is fixed with the sound-absorbing baffle plate, the sound-absorbing plate washer more than or equal to the size of window and and window between suitable distance is arranged, the sound-absorbing baffle plate communicates with the compartment inner chamber with pitch space between the window.
2, advance ventilation window by claim 1 is described, it is characterized in that described sound-absorbing baffle plate and window the inboard, compartment fixedly be a part of edge and compartment wall by being connected the sound-absorbing baffle plate with the plate body or the rod member of compartment wall approximate vertical.
