Indoor crab culture pond water temperature control method

The invention discloses an indoor crab culture pond water temperature control method which comprises the following specific steps: S1, arranging two pedestrian walkways on two sides of a crab pond, and erecting a temperature control room frame structure above the pedestrian walkways and the crab pond, the temperature control room frame structure has the functions of shielding sunlight, controlling the temperature of air around the crab pond and collecting sunlight to convert the sunlight into electric energy. S2, building a spray cooling pipeline structure in the crab pond, wherein the spray cooling pipeline structure is used for spraying cold water into the crab pond to reduce the water temperature of the inner surface of the pond. The temperature control room frame structure is used for adjusting shading to adjust the air temperature in the crab pond, water temperature rise caused by the air temperature is effectively prevented, and solar energy can be absorbed to be used for preparing cold water; the spray
