Air inlet 4 connects, and air accumulator 8 is connect with the gas outlet 5 of snow melt air cushion 1.
A large amount of manually upper roof operations are not required to by this snow-removing device, it is safe and efficient, photovoltaic module 21 is arranged for roof
The case where, snow removing is reduced to roof and photovoltaic module 21, reduces the risk for increasing leakage point.It, can to roof simultaneously by snow melt
With timely loss of weight, building safety in utilization is improved.
The snow melt air cushion 1 further includes for detecting the temperature sensor 10 of temperature in hot gas blister cavities body and being arranged in waste gas heat
On 7 heat source transfer pipeline of source, and the flow control valve for controlling heat source flow.Specifically, staff can be by learning
The intracorporal temperature value of hot gas blister cavities is decreased or turned off flow control valve when temperature is higher, when hot gas blister cavities body temperature is higher
When expand flow control valve opening, avoid temperature excessively high, damage roof structure or the case where photovoltaic panel.
It further include flow control valve, flow control valve is arranged on 7 heat source transfer pipeline of exhaust gas heat source, and for controlling heat
Source flux, temperature sensor 10 and flow control valve are connect with controller 11, and it is big that controller 11 adjusts flow control valve opening
It is small.Specifically, when the temperature value that controller 11 monitors that temperature sensor 10 inputs is more than the first preset temperature, controller 11
Control flow control valve is closed or is turned down；When controller 11 monitors that the temperature value that temperature sensor 10 inputs is pre- lower than second
If when temperature, controller 11 controls flow control valve and fully opens or increase flow control valve aperture.Second preset temperature is small
In the first preset temperature, the second preset temperature is set according to actual needs less than the first preset temperature, and the application does not do specific limit
It is fixed.
Temperature sensor 10, come the temperature of control loop gas, is not only reduced because of cycling hot by the supply of control waste heat source
Temperature spend it is low caused by snow melt low efficiency, can also reduce spend height because of cycling hot temperature caused by snow melt air cushion 1 material heat it is old
The risk of the situations such as change avoids the waste of thermal energy to ensure the efficient progress of snow melt work.
Specifically, staff adjusts the gas feed flow of air pump 6 according to the pressure value of pressure-regulating valve, hot gas is avoided
The case where huge explosion is crossed in air pressure in blister cavities body.
In order to improve the degree of automation, the labor intensity of staff is reduced, it is preferable that controller 11 controls 6 gas of air pump
Feed flow realizes 6 gas feed flow of air pump especially by the pressure value that controller 11 receives baroceptor 12.
When snow-removing device is for snow melt on photovoltaic module 21, so that the snow on photovoltaic module 21 melts in time, Jin Erti
The generating efficiency of high photovoltaic module 21 improves income.
