A kind of aerodynamic lifting liquid device and method using solar energy

Abstract

The invention relates to a device and method for elevating liquid by using solar aerodynamic force. The device comprises a wind tower, a power turbine, a fluid director, a transmission shaft, an elevating impeller, a transparent cover plate, a heat absorption disk, a trapezoidal straight rib, a sealing layer, a thermal insulating layer, an outer shell, air inlet tubes, floating bowls, a connecting rod, a rigid water pipe and a flexible water pipe. The method includes the steps that the heat absorption disk at the bottom of the wind tower converts solar energy into high-temperature heat energy, and the heat energy is transmitted to the air in a heating air chamber below the heat absorption disk through the trapezoidal straight rib; the hot air in a heat collection area of the heating air chamber is gathered at the bottom of the wind tower and then ascends, the fluid director is used for rectification, and then the power turbine in the tower is pushed to rotate to generate rotation power; the rotation power drives the elevating impeller in the rigid water pipe below to rotate through the transmission shaft, and thus vertical upward suction force can be generated to seawater in the pipe. By the adoption of the device and method, the elevating drive force to seawater can be adapted to the size variation of solar input power automatically, and therefore high energy utilization efficiency is achieved.

Description

technical field [0001] The invention belongs to the field of marine technical equipment, and relates to an aerodynamic lifting liquid device and method using solar energy. Background technique [0002] Upwelling is the basis for the formation of high-quality marine fisheries. Upwelling can lift the nutrients in the deep seawater to the light-transmitting layer on the sea surface, thereby improving the environmental conditions of the food chain of seawater fish. Therefore, the sea area with upwelling is one of the most "fertile" sea areas in the ocean. Although its area It only accounts for one-thousandth of the total ocean area, but the fish catch accounts for about half of the world's total ocean fish catch. However, due to the seasonal and regional shortcomings of natural ocean upwelling, the nutrients in some offshore areas of my country often cannot reach the light-transmitting layer near the water surface. [0003] Liquid lifting technology can artificially form upwel...

Problems solved by technology

[0004] At present, the existing artificial upwelling devices mainly include the following three types: one is to use the pump to directly suck the bottom seawater to generate upwelling, such as the "Takumi" equipment in Japan. The disadvantage of this type of device is that it consumes a lot of energy and has low efficiency; Underwater gas injection uses bubbles to rise to drive seawater upwelling to generate upwelling. This type of device increases the complexity and instability of the system due to the need to provide an external gas source in the ocean; in addition, an invention patent with application number 201210000180. A device that uses solar energy and wave energy to increase nutrients. The device uses wave energy to transport solar heat to the seabed through fluid working fluid for heat exchange to generate upwelling. Because the device uses wave energy as the power source for heat transfer, Because solar heat has the characteristics of high daytime and low nighttime intermittent generation, it is difficult for wave energy to match with it in terms of power and time, which easily causes the problem of low heat transfer efficiency
