Compared with prior art the present invention has following characteristics and beneficial effect:
1, the invention solves the out of use at night shortcoming of solar energy air heat collector heating,, also can utilize solar energy to be indoor heating at night except utilizing daytime the solar energy.
2, utilize solar heating, improved indoor comfort level.
3, owing to utilized heliotechnics, reduced the consumption of conventional energy resource, reduced emission amount of carbon dioxide, the protection environment.
4, solar energy resources is abundant and free, has saved the investment of conventional energy resource heating, has improved economic benefit.

The specific embodiment
Embodiment is referring to shown in Fig. 1-4, this solar energy pebble heat storage heating system, comprise pebble heat storage layer 6, pebble heat storage layer 6 is positioned at below the indoor floor 7 in house, grid orifice plate 5 is arranged below the pebble heat storage layer 6, be equipped with built on stilts air channel 4 between grid orifice plate 5 and the ground 10, one side in described built on stilts air channel 4 is communicated with the air inlet 8 of being located at the house wall root, the air outlet 9 of another body of wall root of opposite side and house in built on stilts air channel is communicated with, there is blinds valve 12 at described air inlet 8 places, and there is air exhauster 13 at air outlet 9 places; Be equipped with solar energy air heat collector 1, blowing shaft 2 and upcast shaft 3 above the roof in house, the gas outlet of solar energy air heat collector 1 is communicated with built on stilts air channel 4 by blowing shaft 2, the air inlet of solar energy air heat collector 1 is communicated with upcast shaft 3, and it is indoor that the lower end of upcast shaft 3 extends to the house.The place, gas outlet or downcast 2 places of solar energy air heat collector 1 are provided with pressure fan 14.
Described grid orifice plate 5 is concrete grid orifice plate or steel grating grate.Described built on stilts air channel 4 is by placing the parapet 11 on the ground 10 to be divided into snakelike or S shape, and described parapet 11 is brick parapet or concrete dwarf wall.Described grid orifice plate is placed on the buttress 15.
In the present embodiment, in civil engineering, lay the built on stilts air channel of S shape broken line or snakelike broken line on ground, on built on stilts air channel, lay concrete grid orifice plate or steel grating double-edged fine-toothed comb, on concrete grid orifice plate or steel grating double-edged fine-toothed comb, lay the pebble heat storage layer, be used for accumulation of heat and heat release.Lay prefabricated board at pebble heat storage layer top, as indoor floor.Two ends in built on stilts air channel are provided with two air ports respectively, an installation air exhauster, and as air outlet 9, another installs the blinds valve, as air inlet 8, forms cobble heat release system.
On air inlet 8 next doors vertical blowing shaft 2 is set, the blowing shaft bottom links to each other with built on stilts air channel 4, and the blowing shaft top is stretched out roofing 600mm and left the hole in the side.The position far away at roofing and air outlet 9 corresponding positions sets out ventilating shaft 3, and the upcast shaft bottom is communicated with indoor top board, and the upcast shaft top is stretched out roofing 600mm and left the hole in the side.At roofing solar energy air heat collector 1 is installed, is linked to each other with the reservation hole of pressure fan with downcast 2, upcast shaft 3 with pipeline, so far solar energy air heat collector 1, blowing shaft 2, built on stilts air channel 4, upcast shaft 3 have formed the pebble heat storage system.
The course of work of the present invention:
Open pressure fan daytime, close the closed blinds of air inlet, the pebble heat storage system brings into operation, with storage of solar energy in pebble heat storage layer 6.Close pressure fan night, open the air exhauster of air outlet and the blinds valve of air inlet, cobble heat release system brings into operation, and the heat that is stored in the pebble heat storage layer 6 is delivered to the indoor heating of carrying out.
After placing the solar energy air heat collector 1 of building the roof to be heated by day hot-air is delivered to built on stilts air channel 4 through the pressure fan of 2 li of blowing shafts, heat is stored in the pebble heat storage layer 6 above the built on stilts air channel, air after the release heat is in air outlet 9 inlet chambers, get back in the solar energy air heat collector 1 through upcast shaft 3 again, finish heat-accumulating process one time, circulation and so forth can be with a large amount of storage of solar energy in the pebble heat storage layer.This process is collected solar energy with solar energy air heat collector, as heat storage, is heat transport pathway with blowing shaft, upcast shaft and built on stilts air channel with the cobble in the pebble heat storage layer.
When night, outdoor temperature descended, close pressure fan 14, the operation of pebble heat storage system stops; Open the air exhauster at air outlet 9 places, cobble heat release system brings into operation, hot-air through the driving of air exhauster from built on stilts air channel 4 in air outlet 9 inlet chambers, indoor cold air enters built on stilts air channel through air inlet 8 simultaneously, after pebble heat storage layer 6 heating again in the air exhauster inlet chamber, circulation is and so forth carried out heating with the transfer of heat that stores in the pebble heat storage layer to indoor.This process as radiator body, is a heat transport pathway with air outlet, built on stilts air channel, air inlet with the cobble of pebble heat storage layer.
