Compared with the prior art, the invention has the beneficial effects that:
(1) According to the invention, the heat sources of the geothermal energy equipment and the solar energy equipment are coupled in the coupling heat storage component through the direct heat energy supply module, the heat load of the user side is simulated through the heat load simulation module, and the heat generation amount, the coupling strategy and the pipeline selection strategy are controlled through the control module based on the total heat load amount, the heat utilization temperature and the regulation strategy of the heat utilization equipment of the user side, so that the surplus capacity is avoided to the greatest extent while the supply of the user side is ensured.

(3) According to the invention, the opening degree of the geothermal energy heat source inlet and the opening degree of the solar energy heat source inlet are accurately controlled through the opening degree regulation model, in the process of establishing the opening degree regulation model, the fixed opening degree of the geothermal energy heat source inlet and the fixed opening degree of the solar energy heat source inlet are firstly determined based on the required temperature, the geothermal energy equipment temperature and the solar energy equipment temperature, and as the geothermal energy equipment temperature and the solar energy equipment temperature are variables in a period of time, the possibility of enlargement and the possibility of reduction exist, and in order to further reduce errors, the maximum value of the geothermal energy equipment temperature in a period of time and the minimum value of the solar energy equipment temperature in a period of time are selected to restrain the fixed opening degree of the geothermal energy heat source inlet and the fixed opening degree of the solar energy heat source inlet, and when the temperature changes, the geothermal energy equipment temperature can only be reduced and the solar energy equipment temperature can only be increased. The variable range is reduced, and the opening degree of the heat source is convenient to control better.
(4) Because the geothermal energy equipment temperature can only be reduced, and the solar energy equipment temperature can only be increased, when the opening degree of the two heat source inlets is regulated, the opening degree is regulated and controlled in an opposite way, and based on the fact that the motor is adopted to regulate and control the positions of the first sealing block and the second sealing block simultaneously, for example, when the geothermal energy equipment temperature is reduced, the opening degree of the geothermal energy heat source inlets needs to be reduced, namely K A is reduced, K B is increased, and at the moment, the motor drives the first sliding block to move upwards and simultaneously drives the second sliding block to move downwards, so that the rotating rod rotates clockwise, and then drives the first sealing block to move upwards so as to reduce the opening degree of the geothermal energy heat source inlets.
(5) Because the heat sources entering the electric heating furnace from the geothermal energy heat source inlet and the solar energy heat source inlet have temperature difference, in order to improve the parameter precision of the temperature sensor in the electric heating furnace, two Tesla valves are arranged in the electric heating furnace, the outlet ends of the Tesla valves are obliquely arranged towards the bottom of the electric heating furnace, the heat sources accelerated by the Tesla valves have larger flow velocity, and the fusion speed of the heat sources with different temperatures is improved.
