Solar water heater heat-collecting device
Technical field
The present invention relates to solar water heater heat-collecting device manufacturing technology field, especially a kind of collection solar device of solar water heater.
Background technology
Existing solar water heater heat-collecting device adopts the heat energy of solar absorber plate reception sunshine production to realize the heating to cold water to the heat exchange in water tank, uses to meet the hot water of people in life, production.Solar absorber plate is as a kind of device of collecting energy of water heater, generally the many thermal vacuum endothermic tubes formations of laying side by side that tilt, vacuum heat absorbing pipe outer tube wall is glass material layer, to receive the direct projection of sunlight, film plating layer is provided with to absorb the heat radiation of sunlight in glass material layer, the heat energy that the mode of this light direct projection endothermic tube produces is little, especially when sunray deficiency, the absorber plate of plane then can not produce enough heat energy, the supply of water heater to hot water can not be met separately, needing, electric heat supply device is set in addition heat is provided, energy utilization rate is not high.
Summary of the invention
Problem to be solved by this invention is to provide a kind of solar water heater heat-collecting device, solves when sunlight ray deficiency, the problem of the shortage of heat that existing solar water heater heat-collecting device produces.
In order to solve the problem, technical scheme of the present invention is: this solar water heater heat-collecting device includes water tank, the end face of described water tank is sphere, the delivery port of described water tank is arranged on the end face of this water tank, the upper lid of described water tank has the refraction covers of the spherically shape of raising up, described refraction covers is comprised refraction mirror holder and by the polylith of this refraction mirror holder splicing sunray is refracted to the refractor on described water tank end face, and the top of described refraction covers has for the microscler breach of sunray direct projection to described water tank end face; The diameter position supporting described refraction covers is provided with a supporting seat, and described supporting seat and described refraction covers are that sphere engages, and described supporting seat is arranged on foot rest by a horizontal loops rail.
In technique scheme, more specifically scheme can be: described refractor is quartz lens.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, this solar water heater heat-collecting device adopts the principle of refractor refraction heat absorption to come to hot water heating by solar light focusing to water tank producing a large amount of heat energy, when making sunray deficiency, refractor still can produce higher heat energy by optically focused, meets the needs that people use hot water;
2, the refraction covers with spherical shape of this solar water heater heat-collecting device replaces the absorber plate of the plane of prior art, increases the angle accepting sunray; The microscler breach that refraction covers top is offered, the strongest sunray can be made by this breach direct projection to water tank also meeting the change of sunray direct projection angle in a day, and a sunray part for non-direct projection is refracted on water tank by refractor and produces heat energy;
3, the refraction covers of this solar water heater heat-collecting device is placed on ring rail by supporting seat, refraction covers and supporting seat can be made together to rotate along horizontal loops rail, also refraction covers and supporting seat can be allowed to rotate to an angle along any direction, such people can adjust angle and the position of microscler breach on refraction covers according to the difference of the different direct sunlight angles in season, to accept the strongest direct projection light.

Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This solar water heater heat-collecting device as shown in Figure 1 and Figure 2, it comprises water tank 6, the end face of water tank 6 is sphere, water tank 6 is provided with water inlet 7 and delivery port 8, water inlet 7 is arranged on the bottom of water tank 6 and connects water source, delivery port 8 is arranged on the end face of this water tank 6 and is connected to user terminal and provides hot water for user, delivery port 8 is designed expiring, to reduce the thermal loss at the highest top of water tank 6 temperature of can ensureing that the water of water tank 6 tries one's best at the end face of water tank 6.The upper lid of water tank 6 has the refraction covers of the spherically shape of raising up, described refraction covers is comprised refraction mirror holder 4 and by the polylith of this refraction mirror holder 4 splicing sunray is refracted to the refractor 5 on water tank 6 end face, the top of described refraction covers has for the microscler breach of sunray direct projection to described water tank end face, here refractor 5 is convex lens, and select the splendid quartz material of the performance such as refractive index and penetrability to make, the strongest sunray can be made by this breach direct projection to water tank 8 also meeting the change of sunray direct projection angle in a day, a sunray part for non-direct projection is refracted on water tank 6 by refractor 5 and produces heat energy.The diameter position supporting described refraction covers is provided with a supporting seat 3, and this supporting seat 3 and described refraction covers are that sphere engages, and this supporting seat 3 relative cover can be rotated a certain angle to any direction; Supporting seat 3 is arranged on four foot rests by a horizontal loops rail 2, it is protruding that supporting seat 3 outer wall is provided with an outside circle, this projection is embedded in horizontal loops rail 2, the related refraction covers one on it of supporting seat 3 is coexisted on horizontal loops rail 2 rotate, such people can adjust angle and the position of microscler breach on refraction covers according to the difference of the different direct sunlight angles in season, to accept the strongest direct projection light.
