The traditional connection method is through flanges, but common valves and flanges do not have thermal insulation properties. Therefore, when the heat transfer medium flows through the valves and flanges, some of the heat in the heat transfer medium will be lost, thereby reducing the waste heat recovery rate of the heat transfer medium by the energy station. In view of the above situation, technological innovation is carried out on the basis of the existing modular layout and connection device of distributed green smart energy stations.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 A modular layout and connection device for a distributed green smart energy station includes an energy station module 100, a mine drainage waste heat recovery module 200, an underground equipment waste heat recovery module 300, a surrounding rock heat dissipation recovery module 400, and a connection component 500. The connection component 500 is installed between the energy station module 100 and the mine drainage waste heat recovery module 200, the underground equipment waste heat recovery module 300, and the surrounding rock heat dissipation recovery module 400.

[0022] The connecting assembly 500 includes a manifold insulation pipe 5. The outer wall of the manifold insulation pipe 5 is connected to a first insulation pipe 51, a second insulation pipe 52, and a third insulation pipe 53. The inlets of each of the first, second, and third insulation pipes 53 are connected to a first flange 57. A second flange 58 is fixed to the outer side of the first flange 57 by bolts and nuts. An electrically controlled valve 59 is connected to the outer side of the second flange 58. The electrically controlled valve 59 can be a DN300 diameter electrically controlled butterfly valve. Two sets of semi-insulated boxes 54 are evenly placed on the outer sides of each of the first, second, and third insulation pipes 53. The semi-insulated boxes 54 can be made of polystyrene foam, which has good thermal insulation performance, strong insulation properties, is non-conductive, and does not easily generate electromagnetic interference, thus ensuring the stability of the electrically controlled valve 59. In normal operation, a hinge 551 is fixedly installed at the bottom of the two sets of semi-insulated boxes 54, and a latch 55 is fixedly installed at the top of the two sets of semi-insulated boxes 54. The first flange 57, the second flange 58, and the electrically controlled valve 59 are all located inside the two sets of semi-insulated boxes 54. The two sets of semi-insulated boxes 54 are joined together by the hinge 551 and fixed together by the latch 55 to form a complete insulation box, thereby insulating the first flange 57, the second flange 58, and the electrically controlled valve 59, thus preventing heat loss when the heat transfer medium passes through the first flange 57, the second flange 58, and the electrically controlled valve 59, thereby improving the waste heat recovery rate. After unlocking the latch 55, the two sets of semi-insulated boxes 54 can be opened outwards, so that the first flange 57, the second flange 58, and the electrically controlled valve 59 can be inspected and maintained.

[0023] The energy station module 100 includes a heat pump 11 and a heat storage tank 1. The inlet of the heat storage tank 1 is connected to the outlet of the heat pump 11, and the outlet of the manifold insulation pipe 5 is connected to the inlet of the heat pump 11. The mine drainage waste heat recovery module 200 includes an immersion heat exchanger 2. The outlet of the immersion heat exchanger 2 is connected to the inlet of an electrically controlled valve 59 connected to the outside of the second insulation pipe 52. The underground equipment waste heat recovery module 300 includes a plate heat exchanger 3. The outlet of the plate heat exchanger 3 is connected to an electrically controlled valve connected to the outside of the first insulation pipe 51. The inlet of valve 59 is connected to the surrounding rock heat dissipation and recovery module 400, which includes heat exchange tube 4. The outlet of heat exchange tube 4 is connected to the inlet of electrically controlled valve 59, which is connected to the outside of the third insulation tube 53. A set of temperature sensors 56 is installed at the outlets of the immersion heat exchanger 2, plate heat exchanger 3, and heat exchange tube 4. The temperature sensors 56 can be Pt100 type resistance temperature sensors. By connecting the temperature sensors 56 and the electrically controlled valve 59 to an industrial-grade PLC (programmable logic controller) or a smart IoT controller, the sensor data can be received. Based on the data from the heat exchanger, and through a preset control algorithm, the electrically controlled valve 59 is controlled. When the temperature of the heat transfer medium in the immersion heat exchanger 2 reaches 10℃-35℃, the electrically controlled valve 59 connected to the immersion heat exchanger 2 opens. At this time, the heat transfer medium in the immersion heat exchanger 2 enters the heat pump 11 through the second insulation pipe 52 and the manifold insulation pipe 5 for waste heat recovery. When the temperature of the heat transfer medium in the plate heat exchanger 3 reaches 15℃-45℃, the electrically controlled valve 59 connected to the plate heat exchanger 3 opens. At this time, the plate heat exchanger... The heat transfer medium in heat exchange tube 3 enters the heat pump 11 through the first insulation pipe 51 and the manifold insulation pipe 5 for waste heat recovery. When the temperature of the heat transfer medium in heat exchange tube 4 reaches 10℃-25℃, the electrically controlled valve 59 connected to heat exchange tube 4 opens. At this time, the heat transfer medium in heat exchange tube 4 enters the heat pump 11 through the third insulation pipe 53 and the manifold insulation pipe 5 for waste heat recovery. The heat energy absorbed by heat pump 11 is stored in heat storage tank 1. Check valves need to be installed in the liquid outlets of the first insulation pipe 51, the second insulation pipe 52 and the third insulation pipe 53.

[0024] Working principle: The two sets of semi-insulated boxes 54 are joined together by hinge 551 and then fixed together by fastener 55 to form a complete insulation box. This provides insulation for the first flange 57, the second flange 58 and the electrically controlled valve 59, thereby preventing heat loss when the heat transfer medium passes through the first flange 57, the second flange 58 and the electrically controlled valve 59, thus improving the waste heat recovery rate. After unlocking the fastener 55, the two sets of semi-insulated boxes 54 can be opened outwards, allowing for maintenance of the first flange 57, the second flange 58 and the electrically controlled valve 59.

[0025] The plate heat exchanger 3 is connected to the cooling system of the large underground equipment. Cooling circulating water from the equipment is introduced into the plate heat exchanger 3, where it is heat-recovered by the heat transfer medium. The cooled circulating water then returns to the equipment for further cooling. The immersion heat exchanger 2 is connected to the mine drainage pipe. Mine drainage flows through the immersion heat exchanger 2, transferring heat to the heat transfer medium within it for heat recovery. During this process, a water filtration device is installed at the inlet of the immersion heat exchanger 2 to pre-treat the drainage and prevent impurities from clogging it. Multiple sets of heat exchange tubes 4 are evenly buried in the mine roadway wall at intervals of 3-5 meters. The circulating heat transfer medium within the heat exchange tubes 4 exchanges heat with the surrounding rock, absorbing heat from it. Temperature sensors 56 on the outside of the immersion heat exchanger 2, plate heat exchanger 3, and heat exchange tubes 4 detect the temperature of the heat transfer medium. An industrial-grade PLC (Programmable Logic Controller) is connected to the temperature sensor 56 and the electrical control valve 59. The controller (or smart IoT controller) receives sensor data and controls the electrically controlled valve 59 through a preset control algorithm. When the temperature of the heat transfer medium in the immersion heat exchanger 2 reaches 10℃-35℃, the electrically controlled valve 59 connected to the immersion heat exchanger 2 opens. At this time, the heat transfer medium in the immersion heat exchanger 2 enters the heat pump 11 through the second insulation pipe 52 and the manifold insulation pipe 5 for waste heat recovery. When the temperature of the heat transfer medium in the plate heat exchanger 3 reaches 15℃-45℃, the electrically controlled valve 59 connected to the immersion heat exchanger 2 opens. When the electrically controlled valve 59 connected to the plate heat exchanger 3 is opened, the heat transfer medium in the plate heat exchanger 3 enters the heat pump 11 through the first insulation pipe 51 and the manifold insulation pipe 5 for waste heat recovery. When the temperature of the heat transfer medium in the heat exchange tube 4 reaches 10℃-25℃, the electrically controlled valve 59 connected to the heat exchange tube 4 is opened. At this time, the heat transfer medium in the heat exchange tube 4 enters the heat pump 11 through the third insulation pipe 53 and the manifold insulation pipe 5 for waste heat recovery. The heat energy absorbed by the heat pump 11 is stored in the heat storage tank 1.
