In this embodiment, the top surface of the heating cover 13 is coplanar with the top surface of the casing 11, so that the device has a simple, compact and integrated structure.
The installation process of the invention is as follows:
after the solar heating device 1 and the snow and ash removing device 55 are assembled, the solar heating device 1 and the snow and ash removing device 55 are connected with the circulating fan 2 through the heating pipeline 4, wherein the air inlet of the air inlet cover 15 is connected with the air outlet of the circulating fan 2, the air outlet of the exhaust cover 16 is connected with the heating terminal 3, such as an exhaust pipe 118, the heating terminal 3 is installed on an indoor wall, and the solar heating device 1 can be installed on an outer wall surface or a roof by means of a support frame.
The working process of the invention is as follows: the circulation fan 2 is turned on, the air flow enters the heating cover 13 through the air inlet cover 15, the heat collecting plate 12 collects the heat of the solar energy and transmits the heat to the air flow through the heat conducting plate 141 and the heat radiating fins 142 to heat the air flow, and the heated air flow passes through the exhaust cover 16 and enters the heat supply terminal 3 to complete the heat supply process.
All above-mentioned executive component electric connection to control panel, the last button that can set up two modules of snow removing and deashing of control panel.
When snow removal processing is required to be performed on the upper surfaces of the heat collecting plate 12 and the casing 11, a snow removal key on the control panel is pressed, and the device of the present invention operates as follows:
the electric heating network 18 is opened, the solenoid valves between the exhaust hood 16 and the heating terminal 3 are closed, and the solenoid valves on the return pipe 19, between the intake hood 15 and the fourth branch 57, and between the exhaust hood 16 and the first branch 54 are opened. At the same time, the servo motor 520 is activated to drive the air guiding pipe 51 and the vibration mechanism 53 to move back and forth along the length direction of the heat collecting plate 12. The heated airflow enters the air guide pipe 51 and the power cavity 537 through the first branch pipe 54, the air guide pipe 51 is heated and melts snow contacting with the air guide pipe, the airflow enters the air collection chamber 58 through the one-way valve between the air collection chamber 58 and the heat conduction cavity 511, and because the air collection chamber 58 is communicated with the fourth branch pipe 57, the air pressure in the air collection chamber 58 is small and is not enough to open the one-way valve in the air collection chamber 58, which is communicated with the soot cleaning cavity 512, and the heated airflow flows back to the air inlet hood 15 through the fourth branch pipe 57 and is reheated. The vibration mechanism 53 at this time drives the fan blade 532 to rotate due to the inflow of the air flow, and further drives the pendulum 533 to rotate, so as to generate vibration and transmit the vibration to the whole solar heat supply device 1, thereby facilitating the acceleration and the sliding of the accumulated snow. In addition, since the solenoid valve on the return pipe 19 is also opened, the air flow circulates internally in the solar heating device 1, and the air flow is heated by the electric heating net 18, so that the purpose of melting snow is achieved.
When the ash removing treatment is required to be performed on the upper surfaces of the heat collecting plate 12 and the shell 11, the ash removing key on the control panel is pressed, and the device of the invention can be operated according to the following method:
the electric heating network 18 is closed, the solenoid valves between the exhaust hood 16 and the heating terminal 3, between the intake hood 15 and the branch pipe four 57 are opened, and the solenoid valves on the return pipe 19, between the exhaust hood 16 and the branch pipe one 54 are closed.

The airflow entering the inlet hood 15 is partially guided into the four branch pipes 57, the airflow enters the air collection chamber 58, the air pressure in the air collection chamber 58 is gradually increased, and finally the one-way valve communicated with the ash removal cavity 512 is opened, the airflow in the ash removal cavity 512 is discharged through the air holes 513, and is blown to the top surfaces of the heat collection plate 12 and the machine shell 11, so that the dust accumulated on the top surfaces is cleaned. At this time, the ash removal chamber 512 is not communicated with the second branch pipe 55, so that the vibration mechanism 53 does not operate and does not vibrate. The solar heating device 1 will collect solar energy and heat the air flow in the heating cover 13 to supply heat to the heating terminal 3.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
