Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment, a kind of power distribution cabinet, as shown in Figure 1, including cabinet body 1, the top plate 2 for being horizontally placed on 1 top of cabinet body, setting
The sliding plate 3 for sliding connection vertically above top plate 2 and with cabinet body 1, is set to 3 front and rear sides of sliding plate and blocks in top plate 2
The blocking parts 4 of top, the driving part 5 for driving sliding plate 3 to slide vertically on cabinet body 1, the rain being set to outside cabinet body 1
Drop sensor 6 and the control unit 7 for being coupled to Raindrop sensor 6 and driving part 5.
Several circular air holes 8 are offered on top plate 2, blocking parts 4 includes first baffle 9 and second baffle 10, the
It is provided on one baffle 9 and sets plate chamber 11 for 10 grafting of second baffle sliding.The side of first baffle 9 is hinged on 1 top of cabinet body
Side on, the one end of second baffle 10 far from first baffle 9 and the side of sliding plate 3 are hinged.Sliding plate 3 and second baffle 10
Hinged place above be respectively and fixedly provided with sealing joint strip 12.Therefore when sliding plate 3 rises, the spacing between top plate 2 and sliding plate 3 increases
Greatly, the thermal current of cabinet body 1 to pass sequentially through the spacing between the air hole 8 on top plate 2 and top plate 2 and sliding plate 3 to move
Out, accelerate heat dissipation；Simultaneously because first baffle 9 and second baffle 10 are overturn, first baffle 9 generates opposite with first baffle 9
Sliding；So that the sliding plate 3 of two sides first baffle 9, second baffle 10 and middle part constitutes top cover above top plate 2, prevent
Sundries falls into air hole 8 by top.
The gear for stretching out 1 top of cabinet body is provided on second baffle 10 along 13.The downside for extending outwardly cabinet body 1 along 13 is kept off, into
The waterproof performance of one step promotion cabinet body 1.
Specifically, driving part 5 includes the cylinder 14 for being set to 1 two sides of cabinet body, cylinder 14 is fixed on the outer of cabinet body 1 vertically
On wall, the piston shaft of cylinder 14 is fixedly connected on 3 lower end of sliding plate.Two sides cylinder 14 can be sliding plate 3 under sliding plate 3
The power stablized and slid vertically is provided.
As shown in figure 4, control unit 7 includes delay circuit 15, delay circuit 15 is coupled to Raindrop sensor 6, is preset with
The inspections of raindrop is not detected detecting that the detection signal of raindrop is changed into from output from Raindrop sensor 6 in one delay duration
When surveying signal, output control sliding plate 3 keeps abutting the control signal of top plate 2.
As shown in figure 4, delay circuit 15 includes S/R latch U1 and 555 delay units.Wherein S/R latch U1 includes S defeated
Enter end, R input and Q output；The S input terminal of S/R latch U1 receives high level signal then Q output output high level
Signal, the R input of S/R latch U1 receives high level signal then Q output output low level signal, and works as S/R latch
The output that the S input terminal and R input of U1 receives low level signal then Q output is constant.The S of S/R latch U1 inputs termination
Receive the detection signal of the output of Raindrop sensor 6；Raindrop sensor 6 exports high level when there is raindrop, exports when not having raindrop low
Level.
As shown in figure 4,555 delay units include the first N-type triode Q1,555 timer U2, delay capacitor C1, prolong
When resistance R1, ground capacity C2 and load resistance R2；The base stage of first N-type triode Q1 and the S input terminal of S/R latch U1 connect
It connects, collector connects supply voltage VCC, and emitter is connected to four feet of 555 timer U2, octal and delay capacitor C1
One end；The other end of delay capacitor C1 is connected to one end of six feet of 555 timer U2, two feet and time delay resistance R1；Prolong
When resistance R1 other end ground connection；A foot of 555 timer U2 is directly grounded, and is grounded after five feet connection ground capacity C2, three feet
The R input of latch is connected after connection load resistance R2.When the first N-type triode Q1 is connected, delay capacitor C1 charging is charged
Three feet export low level in the process, and three feet export high level after delay capacitor C1 charges.
As shown in figure 4, therefore when rainy, when Raindrop sensor 6 exports the detection signal of high level, S/R latch U1's
S input terminal input high level, R input input low level, Q output export the control signal of high level；And stopping raining
When, when the detection signal that Raindrop sensor 6 exports is converted into low level from high level, the S input terminal input of S/R latch U1 is low
Level, R input input low level, Q output keep the control signal of output high level；Raindrop sensor 6 exports low level
Detection signal continue delay duration after, S input terminal input low level, the R input input high level of S/R latch U1, Q is defeated
Outlet exports low level control signal.So as to avoid due to occurring continuously having raindrop in 6 short time of Raindrop sensor
And do not have the testing result between raindrop, cause the continuous mutation in a short time of driving part 5.
To sum up, when not raining, control unit 7 controls the driving sliding plate 3 of driving part 5 and slides upwards, increases top plate 2 and slides
The spacing between plate 3 is moved, the thermal current of cabinet body 1 is enabled to pass sequentially through the air hole 8 on top plate 2 and top plate 2 and sliding plate 3
Between spacing remove, accelerate heat dissipation；And when rainy, control unit 7 controls driving part 5 and sliding plate 3 is driven to move down, at this time
Sliding plate 3 and blocking parts 4 move down, and are connected on top plate 2, and the air hole 8 on top plate 2 is blocked, and reduce power distribution cabinet and outside
The area that air mutually circulates can also reduce, and effectively play rain-proof.Therefore this programme can adjust the radiating surface at 1 top of cabinet body
Product, to adapt to a variety of situations.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
