Description
Technical field
The utility model belongs to and utilizes solar energy to carry out energy accumulating and thermal power transfer field, particularly relates to a kind of solar product that industrial and agricultural production or living standard of urban and rural population are used that is applicable to.
Background technology
The central utilization for solar energy of prior art, although had before this lot of thinkings and invention, but the effect that should bring into play with regard to sun the subject of knowledge and the object of knowledge and efficiency, at present also do not have a kind of solar product to reach the degree that makes people comparatively satisfied, that is to say that the good pluripotency in solar energy need further exploitation.Carry out the utilization of solar energy, first will in limited space, assemble energy as much as possible, then this luminous energy is effectively changed, such as converting using value heat energy comparatively widely to, also will reduce the loss of the rear energy of conversion simultaneously as far as possible.Conventionally the mode adopting aspect solar energy gathering is at present that " point " assembled.
For example: utilize lens principle to assemble sunshine, very limited of the energy of assembling due to a single point, so just set of lenses is dressed up to the form of lens arra, the rotation of the bracket of lens arra by its installation in horizontal plane and follow the tracks of the running orbit of the sun in perpendicular do elevating movement, to reach the object that gathers solar energy with sun synchronization track.The drawback of this mode is in order to collect as much as possible enough solar energy, will select as far as possible many focal points, needs as far as possible many lens are installed, although met like this abundant of energy, has but increased the volume of lighting equipment simultaneously.Due to abundant lens will be installed, for the bracket of its underpart, just must increase accordingly volume, increase rigidity, increase rotary power, the weight of bracket is large like this, takes up an area greatly, and mobility is with regard to underaction, and practical and convenient property is good not.
For example: utilize the reflective mode that converges at focus of concave mirror to converge solar energy.It is characterized in that the convergent bowl of dome-type to be placed under sunlight, by the support rotation device of this convergent bowl bottom, to reach, follow the tracks of the object that sun running track gathers solar energy.The shortcoming of this device is, in order to collect as much as possible abundant solar energy, often single dependence increases the internal surface area of convergent bowl, although solved like this problem of optically focused, but the fact of but having brought space to increase, for civilian installations such as families, the situation that spatial dimension is limited, its application is just very unactual.
Can it be the first step that sunlight is converged in the utilization of solar energy, carry out effectively conversion very crucial.What in the middle of prior art, conversion was maximum is heat energy.But because conversion efficiency is limited, heat several premium on currency just needs a very huge device to carry out, if industrial application, the heat supply company that for example central heating is carried out in north of china in winter heating just can not adopt such device completely.Therefore the device of the type is only only applicable to the civilian upper of single household, and its range of application is limited to.
The utilization of solar energy not only needs to converge sunlight, also will effectively change luminous energy, takes precautions against heat-energy losses simultaneously and is also absolutely necessary.Still far from being enough what do aspect strick precaution heat-energy losses in the middle of prior art.The solar water heater of home-use hot water is for example provided for resident, and it,, when sunlight is not abundant, needs the electric energy energy as a supplement.Northern area cold methane gas producing amount in winter is lower, and peasant does not use biogas.If peasant applies this device on methane-generating pit, will higher than obtained combustion gas value, abandon using because of its cost.So the solar water heater in the middle of prior art, fails to solve the problem of northern area peasant use in winter biogas.
For the weak point existing in the middle of prior art, this area is needed badly and is wanted a kind of new method to solve the problems referred to above.
Summary of the invention
