[0024] The working principle and use process of the application: when using the agricultural light complementation mechanism for compound production planting, first, based on actual demand, select the corresponding number of photovoltaic panels 11, align the base 202 to the external ground pile, install the base 202 on the external ground pile, and install the cross seat 209 on the pull rod 207, fix the bracket 216 together with the frame 1 on the rotating rod 215, and finally clamp the photovoltaic panel 11 inside the air cushion 201. Here, according to the actual construction convenience and construction habit, the assembly sequence can be regulated, that is, the assembly of the photovoltaic array mechanism 200 and the frame 1 can be completed first, and then the photovoltaic array mechanism 200 is installed on the external ground pile, and through the corresponding number of photovoltaic array mechanisms 200, each photovoltaic panel 11 is installed on the external ground pile in turn, and the preliminary arrangement and installation work is completed. It should be noted here that under the initial condition, the inside of the side box 211 at the top of the plug cap 212 is filled with sufficient air, that is, the air pressure at the top of the plug cap 212 is sufficient, and the plug cap 212 abuts against the bottom of the side box 211 under the action of air pressure. At this time, the through hole 219 is in communication with the side pipe 213. Before the aforementioned installation work is performed, the air pressure at the top of the plug cap 212 can be observed through the pressure gauge 23. This air pressure is the maximum limiting air pressure between the frame 1 and the photovoltaic panel 11 in the subsequent working process. By injecting air into the inside of the side box 211 through the air valve 22 on the side box 211, the limiting air pressure can be adjusted, and the threshold of the connection stress between the frame 1 and the photovoltaic panel 11 can be limited. While ensuring the stability of the connection, the load pressure of the frame 1 and the photovoltaic panel 11 in the subsequent use process is reduced to avoid deformation and damage due to long-term work under high pressure, and to ensure that they can work more sustainably and stably for a long time. After the aforementioned adjustment and installation work is completed, the hydraulic fluid is injected into the inside of the liquid cavity 217 through the liquid valve 20. Under the action of gravity, the branch plate 205 will press the bottom hydraulic fluid, and then the hydraulic fluid will enter the bladder cushion 203 under the action of pressure, causing the bladder cushion 203 to expand accordingly and press the external ground pile tightly, thereby strengthening the connection stress between the base 202 and the external ground pile. At the same time, under the communication of the side hole 218, the hydraulic fluid will enter the side box 211 simultaneously. At this time, the side pipe 213 and the through hole 219 are in a conductive state. Under the communication of the side pipe 213, the hydraulic fluid will enter the air cushion 201 through the side pipe 213, forcing the air cushion 201 to expand accordingly and simultaneously pressing the frame 1 and the photovoltaic panel 11, thereby strengthening the connection stress between the frame 1 and the photovoltaic panel 11, and using the weight of the device to preliminarily limit and fix the base 202 and the photovoltaic panel 11. Subsequently, the communication valve 21 is opened, and the external pipeline is used to sequentially connect the branch cylinders 206 in series in cooperation with the communication valve 21. Air is injected into the air valve 22 on the arbitrary conduit 210 by using the external air charging device. Under the communication of the external pipeline and the communication valve 21, the air flow synchronously enters each air chamber 220 to supplement the air in the air chamber 220 and adjust the air pressure on the top of the piston 208. At the same time, under the communication of the conduit 210, the air flow enters the space on the top of the support plate 205 in the liquid chamber 217, and forms a resultant force with the gravity to increase the extrusion force of the support plate 205 on the hydraulic liquid on the bottom, so that the air cushion 201 and the bladder cushion 203 can obtain sufficient elastic support, further enhance the holding force of the bladder cushion 203 on the external ground pile and the locking force of the air cushion 201 on the frame 1 and the photovoltaic panel 11, and the photovoltaic array mechanism 200 can double-elastic limit the photovoltaic panel 11 by means of the gravity and the air pressure. In the foregoing installation process, during the final fixation of the base 202 and the photovoltaic panel 11, the air pressure on the top of the support plate 205 can be appropriately reduced, so that the air pressure value is less than the air pressure on the top of the plug cap 212, that is, less than the limiting air pressure threshold, so as to reduce the pressure borne by the photovoltaic panel 11. In the actual working process, when the frame 1 and the photovoltaic panel 11 are impacted by external wind force, they will drag the pull rod 207, forcing the piston 208 to compress the air on the top. Under the communication of the conduit 210, the air pressure on the top of the support plate 205 will synchronously rise, causing the pressure of the hydraulic liquid to synchronously rise under the compression thereof. In this process, as the pressure of the hydraulic liquid rises, the pressure on the bottom of the plug cap 212 will synchronously increase. When the hydraulic liquid pressure on the bottom of the plug cap 212 is sufficient to overcome the limiting air pressure on the top, the plug cap 212 will rise under the push of the hydraulic liquid, disconnecting the side pipe 213 from the through hole 219. At this time, as the air pressure on the top of the support plate 205 rises, the hydraulic liquid no longer enters the air cushion 201, avoiding the pressure of the air cushion 201 on the photovoltaic panel 11 exceeding the maximum limiting air pressure, and further enhancing the locking force of the bladder cushion 203 on the external ground pile. Further, when the external wind force decreases, the piston 208 and the plug cap 212 will reset under the action of the air pressure on the top, the pressure borne by the hydraulic liquid decreases, and the locking pressure borne by the frame 1, the photovoltaic panel 11 and the base 202 decreases, that is, the photovoltaic array mechanism 200 can dynamically convert, superimpose the gravity, the internal air flow pressure and the external wind force, and triple-elastic lock the frame 1, the photovoltaic panel 11 and the base 202. At the same time, the external wind is taken as a disturbance factor, and the external wind is taken as a locking force. In the daily work process, the locking pressure borne by the frame 1, the photovoltaic panel 11 and the base 202 is reduced, and when the external wind is enhanced, the locking pressure borne by the frame 1, the photovoltaic panel 11 and the base 202 is strengthened. In the process of adapting to the external wind disturbance and enhancing the stability, the photovoltaic panel 11 is prevented from working under high pressure for a long time. It should be noted here that in the foregoing installation and adjustment process, the rotating screw rod 222 drives the sliding plate 223 to slide, so that the hydraulic liquid in the sliding box 221 enters the cross seat 209 through the first hole 224 or the tail hole 225 under the pressure of the sliding plate 223, and the shaft plug 214 is driven by the hydraulic pressure to drive the frame 1 to deflect through the rotating rod 215 and the support 216, so as to limit and adjust the angle of each photovoltaic panel 11. At the same time, the sliding rod 204 can be rotated to adjust the retraction amount of the sliding rod 204 relative to the support cylinder 206, so as to adjust and compensate the height of the photovoltaic panel 11, and dynamically optimize the photovoltaic array composed of each photovoltaic panel 11. After the adjustment of the photovoltaic array mechanism 200 is completed, the chuck 304 is pulled out, so that the chuck 304 can rotate relative to the clamping ring 305, the limiting of the connecting shaft 303 is released, the top frame 301 can deflect relative to the frame 1, the angle of the light supplementing plate 302 is adjusted, the reflected light of the light supplementing plate 302 can irradiate on the light splitting plate 306 on the front row frame 1, and the concave mirror of the rear row light supplementing plate 308 is aligned with the convex mirror of the front row light supplementing plate 308 by pressing the light supplementing plate 308. In the daily work process, the sunlight irradiates on the light supplementing plate 302, and under the reflection of the light supplementing plate 302, the light irradiates on the light splitting plate 306 of the front row, the light splitting plate 306 reflects and disperses the light, the bottom side of the photovoltaic panel 11 is preliminarily supplemented with natural light, the crops at the bottom are irradiated, and the light irradiation amount received by the rear row photovoltaic panel 11 is increased. At the same time, the convex mirror of the rear row light supplementing plate 308 receives part of the reflected light of the light splitting plate 306, and reflects the light to the concave mirror of the front row light supplementing plate 308, the concave mirror of the front row light supplementing plate 308 further reflects and disperses the light, the light irradiation amount received by the crops is enhanced, and the PAR value can be monitored in real time through the sensor 310. When the PPFD in the planting area is less than 200 μmol·m - ²·s - ¹, the light bar 309 is automatically activated for light supplementing; After the foregoing adjustment is completed, the planting groove can be arranged at the bottom of the photovoltaic panel 11, and the external planting groove is aligned with the light bar 309 for grid planting. According to the actual needs, the shade-tolerant economic crops such as peony, ginger, sanchi and iron skin stone ophiopogon are selected and bred, the three-dimensional layout of “photovoltaic layer- liana layer- rhizome layer” is adopted, and the composite production planting is carried out. It needs to be added here that in the subsequent working process, the wind deflector 315 will converge the external airflow and guide the airflow to the air casing 314, causing the turbine 313 to rotate the screw rod 311 through the shaft seat 312 and the clamping plate 318 under the action of the airflow. In this process, at the same time, only one side of the shaft seat 312 and the clamping plate 318 will engage with each other, that is, only one side of the turbine 313 can drive the screw rod 311 to rotate at the same time; When the threaded plate 319 is displaced to one end, it will press against the clamping plate 318 on that side, causing the clamping plate 318 on that side to engage with the shaft seat 312, and the shaft seat 312 on the other side will be disengaged from the shaft seat 312. The turbine 313 on that side will drive the screw rod 311 to rotate in the opposite direction, that is, the two turbines 313 will alternately drive the screw rod 311 to reciprocatingly deflect, so that the rolling brush 322 is driven by the mounting head 320 to reciprocatingly displace along with the threaded plate 319, and the light supplementing plate 302 is cleaned. The wiper strip 321 will wipe off the impurities on the rolling brush 322; Further, the amount of natural light supplement received by the planting area at the bottom of the photovoltaic panel 11 can be ensured, crops can be planted in the space below the photovoltaic power station, and the presence of natural light supplement and the light bar 309 can ensure the amount of light while reducing the spacing between the photovoltaic panels 11, thereby improving the land utilization rate.
