Abstract
The utility model discloses an automatic roof spray cooling device, which comprises a solar battery, a timing controller, a solenoid valve and a nozzle arranged on a roof. The nozzle is arranged on the roof and is connected with a tap water pipeline through the solenoid valve, the control end of the solenoid valve is connected with the output end of the timing controller, the power end of the timing controller is connected with the solar battery, and the timing controller is powered by the solar battery. The timing controller is an intermittent on/off timer. When the sunlight radiates, the solar battery generates power, the whole device operates, and the nozzle sprays water to the roof intermittently, thereby reducing the surface temperature of the roof; and when the sunlight is weak or the utility model is used at night or in rainy days, the voltage of the solar battery is low, the whole device can not operate, and no water can be sprayed out, thereby preventing the water waste. The utility model requires no external power supply, and has the advantages of simple structure and high reliability.
Description
Technical field
The utility model relates to building energy saving field, is the automatic device of a kind of roof spray cooling.
Background technology
Building is subjected to the solar radiation heating, and temperature raises.The room of some top layers particularly, because the illumination that the roof is subjected to is the strongest, thereby temperature is very high in the room in, all there is such problem in buildings such as some factory buildings, builder's temporary shed in addition.In order to lower the temperature, present people are at the roofing isolation layer, but effect is bad.The interior temperature height causes air conditioning energy consumption to strengthen, and waste is serious.
The utility model content
The utility model purpose is to provide a kind of device of cooling roof, automatic trickle when solar radiation, and the temperature of reduction roof surface is to reach the purpose of building energy conservation.
Scheme of the present utility model is: roof automatic spray heat sink, comprise the solar cell, timing controller, electromagnetic valve, the shower nozzle that are located on the roof, it is characterized in that: shower nozzle is set on the roof, shower nozzle is connected with tap water pipe line by electromagnetic valve, the control end of electromagnetic valve is electrically connected with the output of timing controller, the power end of timing controller is electrically connected with solar cell, by solar cell for supplying power.
Described timing controller adopts intermittently on-off timing device.
The utility model has the advantages that: use solar cell for supplying power, when solar radiation, solar cell power generation, whole device work, shower nozzle reduces the temperature of roof surface intermittently to the roof trickle; When a little less than the solar radiation or night, overcast and rainy, solar array voltage is low, and whole device can't be worked, and can not spray water, and has avoided the waste of water.This device does not need external power supply, has advantage simple in structure, that reliability is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the electrical schematic diagram of timing controller.
Description of symbols among the figure: 1 solar cell, 2 timing controllers, 3 electromagnetic valves, 4 shower nozzles, 5 tap water pipe lines.
The specific embodiment
Among the embodiment, the aperture that bores arrangement on water pipe is as shower nozzle, and water pipe is laid on the highest point on roof, and in fact also there is the small skew angle on the roof in flat-top room owing to consider draining during design, should make the water of shower nozzle ejection cover whole roof during laying.
Illustrate below in conjunction with Fig. 1:
Shower nozzle 4 is connected shower nozzle 4 water spray work during electromagnetic valve 3 conductings by electromagnetic valve 3 with tap water pipe line 5; When electromagnetic valve 3 ended, shower nozzle 4 was not sprayed water.
The control end of electromagnetic valve 3 is electrically connected with the output of timing controller 2, the conducting of timing controller 2 control electromagnetic valve 3 or end.
The power end of timing controller 2 is electrically connected with solar cell 1, by solar cell 1 power supply that is located on the roof.
When the solar radiation roof, solar cell 1 is subjected to illumination to penetrate generating, whole install electric work, the intermittently conductings of timing controller 2 control electromagnetic valve 3, shower nozzle 4 reduces the temperature of roof surface intermittently to the roof trickle.
When a little less than the solar radiation or night, overcast and rainy, solar cell 1 voltage is low, and timing controller 2 no normal power supplies can't be worked, and electromagnetic valve 3 is in cut-off state, and shower nozzle 4 can not be sprayed water.
The timing controller of embodiment adopts intermittently on-off timing device, as shown in Figure 2.
