[0040] See also Figure 5 The energy monitoring and control system of the present invention also includes a battery-assisted fixing mechanism 100. The battery-assisted fixing mechanism 100 includes a first support plate 10, a support rod 20 and an anti-shake assembly 30. The first support plate 10 is placed on the top of the support rod 20 and is tilted. The solar cell 5 is placed on the first support plate 10, and the solar cell 5 is tilted along with the first support plate 10, so it is convenient for users to use. Preferably, the inclination angle of the first support plate 10 to the horizontal plane is 45°. The bottom end of the support rod 20 is used to be inserted into the ground to support the first support plate 10 and the solar cell 5.

[0041] The anti-shake assembly 30 includes an auxiliary fixing tube 31, a metal heat-conducting net 32, a liquid guide tube 33, a first liquid storage tank 34, an electric heating element 35, a first piston 36, a first electric cylinder 37 and a controller 38. The auxiliary fixing tube 31 is used to be inserted into the ground and sleeved on the support rod 20. A flow guide space 311 is formed between the auxiliary fixing tube 31 and the support rod 20. The flow guide space 311 is cylindrical. The metal heat-conducting net 32 ​​is coated on the outer peripheral surface of the support rod 20 and is located in the flow guide space 311. The first end of the liquid guide tube 33 is connected to the upper end of the first liquid storage tank 34, and the second end of the liquid guide tube 33 is connected to the upper end of the flow guide space 311. The first liquid storage tank 34 stores a reversible phase change material, and the first liquid storage tank 34 is fixed on a bracket 39. Among them, the reversible phase change material can be an organic phase change material or a composite phase change material, etc., which is not specifically limited here. In one embodiment, the reversible phase change material may be paraffin or a composite phase change material containing paraffin.

[0042] The electric heating element 35 is electrically connected to the controller 38, and is used to heat the reversible phase change material so that the reversible phase change material changes from a solid state to a liquid state. The first piston 36 is located in the first liquid storage tank 34, and is used to squeeze a preset volume of liquid reversible phase change material into the guide space 311 each time. The first electric cylinder 37 is electrically connected to the controller 38, and is used to drive the first piston 36 to move. When the support rod 20 is loose, the controller 38 controls the electric heating element 35 to generate heat, so that the reversible phase change material changes from a solid state to a liquid state, and then the first electric cylinder 37 drives the first piston 36 to move downward to squeeze the reversible phase change material, so that the liquid reversible phase change material flows into the guide space 311. The liquid reversible phase change material flows into the guide space 311 and undergoes a phase change after being cooled, thereby becoming a solid state, thereby reinforcing the loose support rod 20, and better avoiding the problem of users easily triggering by mistake when the support rod 20 is loose.

[0043] Since the metal heat-conducting net 32 ​​is coated on the outer peripheral surface of the support rod 20 and is located in the flow-conducting space 311, when the reversible phase-change material that becomes liquid after being heated flows into the flow-conducting space 311, the heat can be transferred to the metal heat-conducting net 32, and the metal heat-conducting net 32 ​​can transfer the heat to the previously injected reversible phase-change material at the bottom of the flow-conducting space 311. The previously injected reversible phase-change material can be converted from solid to liquid, so as to refill the gap around the support rod 20, making the support rod 20 more firmly and reliably fixed, and better avoiding the problem of unreliable fixation caused by the upper end of the support rod 20 being pried by external force, resulting in a gap at the bottom of the support rod 20.

[0044] The battery-assisted fixing mechanism 100 of the present invention further includes a tilt monitoring assembly 40, which includes a pressure sensor 41 and a sensor fixing rod 42. The pressure sensor 41 is mounted on the sensor fixing rod 42 and forms a gap with the support rod 20. The pressure sensor 41 is electrically connected to the controller 38 and is used to detect whether the support rod 20 is tilted, so as to send a pressure signal to the controller 38 when the support rod 20 is tilted. The controller 38 is also used to control the electric heating element 35 and the first electric cylinder 37 to work in sequence when it is detected that the pressure on the pressure sensor 41 is greater than a preset value and lasts for a preset time greater than a preset time.

[0045] Among them, the pressure sensor 41 is located behind the support rod 20. When the user uses it, if the solar cell 5 is hit by rain or hail, the support rod 20 leans back, thereby squeezing the pressure sensor 41. At this time, when the controller 38 detects that the pressure on the pressure sensor 41 is greater than the preset value and the preset time is greater than the preset time, it controls the electric heating element 35 and the first electric cylinder 37 to work in sequence, so as to melt the phase change material on the first liquid storage tank 34 and inject it into the guide space 311, so as to automatically reinforce the support rod 20, which not only reduces the maintenance cost but also delays the service life. It can be understood that the preset value and preset time of the pressure can be set as needed, and no specific limitation is made here. Preferably, the preset time is greater than 1 hour. Since the controller 38 controls the electric heating element 35 and the first electric cylinder 37 to work in sequence only when the preset time is greater than the preset time, misjudgment can be avoided.

[0046] The battery auxiliary fixing mechanism 100 of the present invention also includes a negative pressure generating component 50, which includes a liquid-blocking and breathable ring 51, a first vent pipe 52 and an exhaust member 53. The liquid-blocking and breathable ring 51 is sleeved on the support rod 20. The liquid-blocking and breathable ring 51 can be made of a metal material with micropores or a breathable material. The outer peripheral surface of the liquid-blocking and breathable ring 51 abuts against the inner wall surface of the auxiliary fixing tube 31, and the inner peripheral surface of the liquid-blocking and breathable ring 51 abuts against the outer peripheral surface of the support rod 20. The liquid-blocking and breathable ring 51 divides the guide space 311 into a first cavity and a second cavity. The first cavity is connected to the guide tube 33 and is used to accommodate the reversible phase change material flowing from the guide tube 33.

[0047] The first end of the first vent pipe 52 is connected to the suction piece 53, and the second end of the first vent pipe 52 is connected to the second cavity. The suction piece 53 is used to suck the air in the second cavity so that the reversible phase change material in the first cavity flows toward the direction of the second cavity. The suction piece 53 can be a cylinder electrically connected to the controller 38, etc. When the first electric cylinder 37 drives the first piston 36 to inject the reversible phase change material from the first liquid storage tank 34 into the first cavity, the suction piece 53 is controlled to perform suction at the same time, so that the liquid reversible phase change material in the first cavity flows toward the direction of the second cavity, so that the liquid reversible phase change material is better filled into each gap corner in the first cavity, thereby improving the strength of the structure.

[0048] In this embodiment, the air extraction member 53 includes a fixed column 531, a second support plate 532, a foot pedal 533, an elastic bellows 534, a one-way valve 535, a first spring 536, a second spring 537 and a second electric cylinder 538. The fixed column 531 is used to be inserted into the ground. The second support plate 532 is fixed to the upper end of the fixed column 531. The foot pedal 533 is spaced apart from the second support plate 532 and is located above the second support plate 532. The elastic bellows 534 is located between the second support plate 532 and the foot pedal 533, the upper end surface of the elastic bellows 534 is sealed and connected to the foot pedal 533, and the lower end surface of the elastic bellows 534 is sealed and connected to the second support plate 532.

[0049] The first vent pipe 52 is in communication with the inner cavity of the elastic bellows 534, and the one-way valve 535 is installed on the side wall of the elastic bellows 534 to guide the gas in the inner cavity of the elastic bellows 534. The first spring 536 and the second spring 537 are both located between the second support plate 532 and the foot pedal 533, the first spring 536 is located on the first side of the elastic bellows 534, and the second spring 537 is located on the second side of the elastic bellows 534. The first end of the first spring 536 elastically abuts against the foot pedal 533, and the second end of the first spring 536 elastically abuts against the second support plate 532. The first end of the second spring 537 elastically abuts against the foot pedal 533, and the second end of the second spring 537 elastically abuts against the second support plate 532. The first spring 536 and the second spring 537 are axially symmetrical about the center line of the elastic bellows 534.

[0050] The second electric cylinder 538 is connected to the second support plate 532 and is electrically connected to the controller 38, and is used to prevent the foot pedal 533 from moving toward the second support plate 532 when the first electric cylinder 37 is in a non-working state, and is spaced apart from the foot pedal when the first electric cylinder 37 is in a working state. That is, when the first electric cylinder 37 is in a working state, the liquid reversible phase change material is driven to the first cavity. At this time, under the control of the controller 38, the upper end of the second electric cylinder 538 is spaced apart from the foot pedal 533. When the user steps on the foot pedal 533 or the maintenance personnel steps on the foot pedal 533, the gas is squeezed out from the one-way valve 535.

[0051] See also Figure 6 In another embodiment, the battery-assisted fixing mechanism 100 of the present invention further includes a green plant auxiliary component 60, and the green plant auxiliary component 60 includes a second liquid storage tank 61, a second piston 62, a first drive rod 63 and a nutrient solution discharge pipe 64. The second liquid storage tank 61 stores plant nutrient solution, the second piston 62 is located in the second liquid storage tank 61, and the first drive rod 63 is connected to the second piston 62 and the foot pedal 533. The upper end of the nutrient solution discharge pipe 64 is connected to the second liquid storage tank 61, and the lower end of the nutrient solution discharge pipe 64 is used to be placed in the ground. Therefore, when the user steps on the foot pedal 533 or the maintenance personnel steps on the foot pedal 533, the plant nutrient solution is automatically injected around the support rod 20, so that the root system of the surrounding plants is more developed, so as to better fix the support rod 20, without the need for hardening the fixation, which is more environmentally friendly.

[0052] The battery auxiliary fixing mechanism 100 of the present invention further includes a rainwater collection assembly 70, which includes a third liquid storage tank 71, a rainwater inlet pipe 72 and a rainwater drainage pipe 73. The first end of the rainwater inlet pipe 72 is connected to the first support plate 10 for collecting rainwater on the first support plate 10, and the second end of the rainwater inlet pipe 72 is connected to the third liquid storage tank 71 to inject rainwater into the third liquid storage tank 71. The rainwater drainage pipe 73 is connected to the nutrient solution discharge pipe 64 and the third liquid storage tank 71 to discharge the rainwater collected in the third liquid storage tank 71 into the nutrient solution discharge pipe 64, so as to output the rainwater and nutrient solution to the earth, thereby achieving the functions of drainage and watering, and making the plant root system grow faster.

[0053] The rainwater collection assembly 70 of the present invention further includes a third piston 74, a second vent pipe 75 and a second driving rod 76. The third piston 74 is located in the upper end of the third liquid storage tank 71. The third piston 74 divides the inner space of the third liquid storage tank 71 into an air storage chamber 711 and a water storage chamber 712. One end of the second vent pipe 75 is connected to the rainwater inlet pipe 72, the other end of the second vent pipe 75 is connected to the air storage chamber 711, and the second end of the rainwater inlet pipe 72 is connected to the water storage chamber 712. One end of the second driving rod 76 is connected to the first driving rod 63, and the second end of the second driving rod 76 is connected to the third piston 74. Therefore, when the user steps on the pedal 533 or the maintenance personnel steps on the pedal 533, the third piston 74 moves downward, and water and plant nutrient solution are automatically injected around the support rod 20. Moreover, air is pumped through the second vent pipe 75, so that the probability of clogging of the rainwater inlet pipe 72 can be reduced.

[0054] In summary, the present invention cooperates between the energy monitoring module 1, the controller 2, the inverter 3, the tracker 4 and the solar cell 5. The energy monitoring module 1 is used to monitor the energy fluctuations of the power grid and the load, and send the energy data to the controller 2. The controller 2 is used to control the output of the inverter 3 in real time according to the energy data, and send the energy data to the mobile phone in real time. The inverter 3 is used to transmit the electric energy of the solar cell 5 to the power grid. The tracker 4 is used to detect the working voltage and current of the solar cell 5 in real time to adjust the power of the solar cell 5. Therefore, when the inverter 3 detects that there is a feeding current, the output power is reduced by derating operation and other measures, and the feeding current is adjusted to zero, that is, automatic zero feeding control is realized, allowing current to be absorbed from the power grid. Such control can effectively manage the flow of electric energy in the power grid, optimize the efficiency of energy use, and reduce the user's dependence on the power grid.
