DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0020] Example like Figure 1-5 As shown, this embodiment provides an automatic control device for substations, including a plurality of spaced-apart solar panels 1, a transformer, and a processing center, wherein the transformer is electrically connected to a plurality of loads and supplies power to the loads; wherein the solar panel 1 is electrically connected to an energy storage device 9, the energy storage device 9 is electrically connected to an inverter, the inverter is electrically connected to a plurality of loads and supplies power to the loads, and the processing center is communicatively connected to the inverter.

[0021] Specifically, the transformer supplies power to several loads, which can be regarded as several farmers. The processing center is used to control the inverter to supply power to the loads. When the power consumption of the farmers is small, the processing center controls only the inverter or transformer to supply power to the loads. When the power consumption is large, the transformer and the inverter are used to supply power to the loads at the same time. The power generated by the solar panel 1 is effectively used to avoid waste.

[0022] Specifically, the communication connection refers to a wired or wireless connection mode that can transfer information to each other, including but not limited to electrical connection, wifi connection, etc. The processing center is preferably a CPU.

[0023] Furthermore, the solar panel 1 is provided with a light sensor, which is communicated with the processing center. The processing center controls the inverter to supply power to the load according to the signal transmitted by the light sensor. The light sensor is used to identify the brightness. In rural areas, the electricity usage is relatively small during the day. At this time, supplying power to the load through the inverter may result in partial waste of electricity. Therefore, the electric energy generated by the solar panel 1 is stored by the energy storage device 9 during the day, and at night, when the brightness is lower, 1 supplies power to several loads through the energy storage device 9. If necessary, a combined power supply method can be adopted to ensure that the electricity is fully used while ensuring the power supply.

[0024] Furthermore, the solar panel 1 is provided with a mounting column 2, the mounting column 2 is rotatably connected to a mounting platform 3, the mounting platform 3 is provided with a rotary power source 4, the rotary power source 4 is provided with an output end, the output end is connected to a first transmission gear 7, the outer peripheral surface of the mounting column 2 is provided with a second transmission gear 6 meshingly connected to the first transmission gear 7; the rotary power source 4 is electrically connected to the processing center. The light sensor is used to identify the brightness. When the processing center determines that the power generation of the solar panel 1 is seriously inconsistent with the power generation that should be achieved at the brightness, the processing center sends a signal to control the rotary power source 4 to output power, the output end rotates, and then drives the first transmission gear 7 and the second transmission gear 6 to rotate synchronously, and then adjusts the angle of the solar panel 1, and stops rotating when the solar panel 1 is approximately the same as the power generation that should be achieved at the brightness. The purpose of chasing light is achieved. The rotary power source 4 is preferably a motor.

[0025] Furthermore, the mounting platform 3 is connected with a connector 5, one end of the connector 5 is connected to the mounting platform 3, and the other end of the connector 5 is connected to a mounting base 15, the mounting base 15 is provided with mounting holes at intervals, and reinforcing ribs 8 are provided at intervals between the mounting base 15 and the connector 5, and the reinforcing ribs 8 are roughly in a right-angle trapezoidal shape. The solar panel 1 is installed on the photovoltaic pile through the mounting base 15, the connector 5 is used to ensure the installation height of the solar panel 1, and the reinforcing ribs 8 are used to strengthen the connection strength between the mounting base 15 and the connector 5 to ensure the stability of the solar panel 1.

[0026] Furthermore, it also includes a first temperature sensor, which is electrically connected to the processing center. The processing center controls the inverter to supply power to the load according to the signal transmitted by the first temperature sensor. The first temperature sensor is used to identify the outside temperature. When the outside temperature is greater than or equal to 30° or less than or equal to 10°, it is judged that there is a certain power supply demand even during the day. At this time, the power generated by the solar panel 1 can be directly used for the load without being transferred through the energy storage device 9, so as to avoid a certain amount of energy loss in the transfer process, further save electricity, and maximize the benefits generated by the solar panel 1. The solar panel 1 is connected to the inverter so that the power generated by the solar panel 1 can be directly used by the load.

[0027] Furthermore, a temperature regulating sleeve 11 is mounted on the outside of the energy storage device 9, and the energy storage device 9 and the temperature regulating sleeve 11 are enclosed to form a temperature regulating space. The energy storage device 9 is provided with a groundwater inlet 10 and a groundwater outlet, and the groundwater inlet 10 and the groundwater outlet are respectively arranged on both sides of the energy storage device 9, and the groundwater inlet 10 and the groundwater outlet are both connected to the temperature regulating space. The energy storage device 9 is preferably a chemical storage battery. During use, its use temperature must be guaranteed to ensure its power storage capacity and service life. Since it is installed outdoors, the temperature of the energy storage device 9 needs to be regulated by the temperature regulating sleeve 11. The temperature of groundwater, especially deep groundwater, is basically not affected by changes in the surface environment, and rural areas have more groundwater resources. By selecting groundwater of a suitable depth (the depth of groundwater is related to the temperature) and passing it into the temperature regulating sleeve 11, the temperature of the energy storage device 9 is guaranteed, and its power storage capacity and service life are ensured.

[0028] Furthermore, the groundwater inlet 10 is connected to a pump body, which is electrically connected to the processing center. A second temperature sensor is arranged near the groundwater outlet in the temperature control space, and the second temperature sensor is electrically connected to the processing center. The second temperature sensor is used to identify the temperature of the groundwater discharged from the temperature control space. When the temperature is significantly different from the temperature of the groundwater introduced into the groundwater inlet 10, the processing center controls the pump body to speed up the flow rate of the groundwater to ensure its temperature control capability.

[0029] Furthermore, a sealing member is provided between the temperature regulating sleeve 11 and the energy storage device 9. The sealing member is used for sealing to prevent groundwater from entering the energy storage device 9 and damaging the energy storage device 9.

[0030] Furthermore, the sealing member includes a sealing ring 14. The sealing ring 14 is used for sealing to prevent groundwater from entering the energy storage device 9 and damaging the energy storage device 9.

[0031] Furthermore, the seal also includes a sealing capsule 12, the energy storage device 9 is provided with a first annular groove 13 adapted to the sealing capsule 12, an adhesive is provided between the first annular groove 13 and the sealing capsule 12, the temperature regulating sleeve 11 is provided with a second annular groove adapted to the sealing capsule 12, and the sealing capsule 12 is filled with helium. The sealing effect of the sealing ring 14 at the corner is poor, and the sealing effect is enhanced by the sealing capsule 12. The sealing capsule 12 can be inflated to fill the gap between the energy storage device 9 and the temperature regulating sleeve 11 as much as possible to ensure the sealing effect. At the same time, the sealing capsule 12 is filled with helium, and the thermal expansion coefficient of helium is high. When the external temperature is high, a faster groundwater flow rate is required to adjust the temperature of the energy storage device 9. At this time, the temperature in the temperature regulating space is high, and the sealing effect of the sealing capsule 12 is enhanced by the expanded helium.

[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
