Description
Technical field
The utility model belongs to accumulator box aeration technology field, and in particular to a kind of accumulator box novel ventilation device.
Background technology
Batteries are the control indispensable pith of power supply in railcar, are subway low-voltage power supply systems
Heart, no matter how complicated electric power system is, its electrical performance ultimately depends on its battery, if battery malfunction, then it is complete
Kind electric power system can not also provide low-voltage power supply.Electric production of the accumulator box of assembled batteries group in city rail vehicle
Also very important effect is just played in technique.
At present, the battery that railcar uses is based on NI-G and plumbic acid two types, both operationally usually companions
There are heat and pernicious gas, distribute the life-span that can influence batteries not in time, can be stopped when serious.Now need
A device that can be divulged information with the external world.
Common ventilation unit is in casing top perforate, realizes that inside and outside gas is handed in tapping welding ventilation unit
Change.The defects of program is that the ventilation unit is welded onto casing top, it is necessary to higher welding procedure is horizontal, frequently results in case
It is uneven at the top of body, influence attractive in appearance.It is more serious polluting meanwhile the device can not effectively prevent the dust of bulky grain from entering
Region, can be covered with dust all over inside operation a period of time rear box, influence the later maintenance of equipment.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of structure independence, is conveniently replaceable dimension
Shield and the accumulator box novel ventilation device that dust entrance can be reduced as far as possible.
To realize above-mentioned technical purpose, the utility model uses following technical scheme：
Accumulator box novel ventilation device, including the ventilation support on the outside of accumulator box is removably mounted to, the ventilation
The bottom of support is provided with air inlet, and the air inlet of the ventilation support is detachably provided with screen pack；The ventilation support
Sidepiece be provided with the air outlet being connected with the inside of the accumulator box, on the ventilation support positioned at the air inlet with
S types labyrinth is provided between the air outlet.
Preferably, it is provided with seal gasket between the ventilation support and the accumulator box.
Preferably, some bolts hole are offered on the ventilation support, the screen pack and seal gasket difference
It is detachably connected by bolt and the ventilation support.
Due to there is at least following beneficial effect using above-mentioned technical proposal, the utility model：
(1) present apparatus belongs to a separate unit, is bolted, and enhances reliability on the original basis, can tie up
Shield property；
(2) present apparatus is while preventing rainwater from entering, moreover it is possible to effectively prevents the dust of bulky grain from entering, in guard box body
Portion is clean and tidy, clean.
Brief description of the drawings
The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.Wherein：
Fig. 1 is the configuration schematic diagram of the utility model embodiment；
Fig. 2 is the schematic side view of the utility model embodiment；
Fig. 3 be in Fig. 2 A-A to structural representation.
Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through
Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with
Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model
Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim
Scope.
As shown in Figure 1 to Figure 3, accumulator box novel ventilation device, including be removably mounted to accumulator box and (do not show in figure
Go out) on the outside of ventilation support 1, the bottom of the ventilation support 1 is provided with air inlet, and the air inlet of the ventilation support 1 can
Screen pack 2 is removed and installed, screen pack 2 is assemblied in ventilation support air inlet position, and specification is 100 mesh, for preventing bulky grain
Dust enter, can dismantle and safeguard in use for some time；The sidepiece of the ventilation support 1 is provided with and the electric power storage
The air outlet that the inside of pond case is connected, S is provided between the air inlet and the air outlet on the ventilation support 1
Type labyrinth 3, the effect in the labyrinth are to limit the flow direction of air, add cut-off on the air channel that script can go directly, outside
Portion's air passes through S types labyrinth from the air inlet of ventilation support 1, reaches the air outlet of ventilation support, the air outlet and accumulator box
Internal run-through, inside this process prevention rain penetration to accumulator box；The ventilation support 1 and the accumulator box it
Between be provided with seal gasket 4, the sealing that seal gasket 4 is used between ventilation support and accumulator box, prevent rainwater from both it
Between gap penetration to inside accumulator box.
In the present embodiment, some bolts hole 5, the screen pack 2 and the seal gasket are offered on the ventilation support 1
4 are detachably connected by bolt 6 and the ventilation support 1 respectively, are conveniently replaceable maintenance.
With reference to figure 3, during work, the lower end of ventilation support 1 is air inlet, and the air stream of air inlet passes through filter screen 2, wherein
Bulky grain dust be limited in outside ventilation support 1, when the air and rainwater after filtering pass through easy S types labyrinth, rainwater
It is excluded in labyrinth, remaining part enters the inside of accumulator box, and ventilation function is provided for batteries.
The schematical embodiment of the utility model is the foregoing is only, is not limited to model of the present utility model
Enclose.Any those skilled in the art, it is made on the premise of design of the present utility model and principle is not departed to be equal
Change and modification, the scope of the utility model protection all should be belonged to.
