Self-power-supply louver-type solar pond heat storage device

Abstract

The invention relates to a solar pond heat storage device comprising a pond body, a frame placed at an opening of the pond body and louver flakes with the edges provided with sealing spacers and further comprising a light intensity sensor, a storage battery, a motor and a wind speed monitor or a humidity sensor which are connected with a central control platform. When the sun irradiates in the high sky, the central control platform perceives the solar elevation angle according to the light intensity sensor and sends a signal to the motor so as to control the opening and closing angles of the louver flakes to enable the louver flakes to be parallel to sunlight; when the situation that the environment wind speed is higher than the critical wind speed is monitored by the wind speed monitor or the situation that the environment humidity is higher than the critical humidity is monitored by the humidity sensor, the central control platform sends a signal to the motor so as to control the louver flakes to be completely closed. Operation of the solar pond heat storage device is not affected by overlarge wind power or over-humid weather, and the situation that the heat storage capacity of a solar pond is destroyed by the disadvantageous environment is avoided.

Description

Technical field [0001] The invention relates to a solar pool heat storage device, in particular to a self-powered louvered solar pool heat storage device. Background technique [0002] The solar pond is a salt pond with increasing salinity from top to bottom, which can absorb and store solar energy in a large area. The solar pool is generally composed of three layers, the surface is the upper troposphere (UCZ) with low temperature and salinity, the temperature is close to the atmospheric temperature, usually fresh water or salt water with a small concentration, the UCZ layer is very thin; the middle layer is called non The troposphere (NCZ), also known as the salt gradient layer, is an important component. The salinity and temperature of this layer gradually increase with depth, forming a non-convective layer; the bottom layer of the solar pool is called the lower troposphere (LCZ) or thermal storage layer. The layer has the highest temperature and salinity, which is close to sa...

Problems solved by technology

[0003] As an open-air thermal storage device, the operation of the existing solar pond is easily affected by the external climate conditions. This is manifested in, first, excessive precipitation will affect the stability of the solar pond surface and the internal concentration gradient; Secondly, when the wind force reaches a certain level, it will also affect the stability of the large solar pool, causing fluctuations or even waves on the water surface of the solar pool, thereby disturbing the stability of the entire pool water; finally, if the outside temperature is low, it will reach freezing conditions and continue to If the time is long, the surface of the solar pool will freeze, resulting in a decrease in transmittance, thereby weakening the heat storage capacity of the solar pool
