Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment, a kind of heat dissipation power distribution cabinet, as shown in Figure 1, including cabinet body 1, being set to 1 top of cabinet body and slided with cabinet body 1
The top cover 2, the driving part 4 for driving top cover 2 to slide vertically on cabinet body 1, the raindrop being set to outside cabinet body 1 for moving connection pass
Sensor 3 and the control unit 5 for being coupled to Raindrop sensor 3 and driving part 4.
As shown in Figure 1, 2, top cover 2 includes the cover board 6 and vertical 6 edge of cover board and and the cabinet of being connected to for being horizontally placed on upper end
The air permeable plate 7 that 1 inner wall of body abuts offers several air holes 8 on air permeable plate 7, and air hole 8 is in vertical strip in the present embodiment
And it is uniformly distributed along the circumferential direction of air permeable plate 7.The edge of cover board 6 is outward extended with weather shield 9.And the upper end inclination of weather shield 9 is set
It is equipped with water guide face, the low side in water guide face is set to towards outside.In addition it is fixed in the bottom of weather shield 9 and abuts 1 upper end of cabinet body
Sealing ring 10.When top cover 2 slides upwards, air permeable plate 7 exposes, and outside air passes through gas phase stream in air hole 8 and power distribution cabinet
It is logical, accelerate heat dissipation；When weather shield 9 is connected to 1 upper surface of cabinet body by sealing ring 10, prevent rainwater from air permeable plate 7 and cabinet body 1 it
Between gap in flow into cabinet body 1；Good sealing effect can be played.
As shown in Figure 1, 2, Raindrop sensor 3 detects whether outside rains, and control unit 5 is according to whether output of raining is different
Control signal；4 connecting cover plate 6 of driving part receives control signal, and moves up or move down according to control signal driving cover board 6.
Detect whether rain by Raindrop sensor 3, control unit 5 is based on Raindrop sensor 3 and controls driving part 4, it is rainy at present
It moves top cover 2 and keeps sealing, the enhancing heat dissipation of top cover 2 is moved up when not having rain；Realize the automation control to power distribution cabinet heat dissipation area.
As shown in Fig. 2, the pedestal of two cylinders 11 is respectively hinged at cabinet specifically, driving part 4 includes two cylinders 11
On the side wall of the two sides of body 1, and the piston shaft of cylinder 11 is hinged on the bottom of weather shield 9.Weather shield 9 is connected on cabinet body 1
When, cylinder 11 is in horizontally disposed.Therefore two cylinders 11 can be the power that weather shield 9 provide that stabilization slides vertically, and due to
The bottom of cylinder 11 and piston shaft are respectively hinged on the outer wall of cabinet body 1 and the bottom of weather shield 9, living when piston shaft stretches out
Horizontal distance between plug axis and pedestal can not be changed, and cylinder 11 can be gradually swung up, and weather shield 9 is gradually lifted up.
As shown in figure 3, control unit 5 includes delay circuit 12, delay circuit 12 is coupled to Raindrop sensor 3, is preset with
One delay duration, for detecting that the detection signal of raindrop is changed into from Raindrop sensor 3 from output raindrop being not detected
Detection signal when, output control cover board 6 keep low level control signal.
As shown in figure 3, delay circuit 12 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 3；Raindrop sensor 3 exports high level when there is raindrop, exports when not having raindrop low
Level.
As shown in figure 3,555 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 3, therefore when rainy, when Raindrop sensor 3 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 3 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 3 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 3 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 4.
To sum up, when not raining, control unit 5 controls driving part 4 and top cover 2 is driven to slide upwards, at this time under cover board 6
Air permeable plate 7 will be gradually exposed, and being gradually exposed with air permeable plate 7, power distribution cabinet also can with the area that outside air mutually circulates
It increases, accelerates heat dissipation；And when rainy, control unit 5 controls driving part 4 and top cover 2 is driven to slide downwards, at this time under cover board 6
Air permeable plate 7 return in cabinet body 1 and abutted with 1 inner wall of cabinet body, and with the gradually withdrawal of air permeable plate 7, power distribution cabinet with outside
The area that portion's 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.
