When disasters occur, not only can they cause core equipment failures such as photovoltaic component fragmentation, support deformation, and inverter damage, but also can lead to power transmission line interruptions and foundation engineering instability, causing large-scale power outages and significant economic losses, and even threatening the safety of surrounding personnel. Therefore, conducting disaster resistance simulation and risk warning for mountain photovoltaic power stations, identifying disaster hazards in advance, optimizing disaster resistance design, and developing precise emergency plans are core requirements for ensuring the safe operation of mountain photovoltaic power stations.

[0050] The spring rod 5013 is used to promote the reset of the bearing support arm 5011 and the guide slider 5012, the top guide block 5014 is fixedly arranged at one end of the bearing support arm 5011, the assembly mechanism further comprises an external wiring harness 5015, a wiring head 5016 and a limiting hole 5017, the bearing support arm 5011 is internally provided with a through hole, the external wiring harness 5015 is fixedly arranged in the bearing support arm 5011, the wiring head 5016 is fixedly arranged at one end of the external wiring harness 5015, one end of the bearing support arm 5011 is provided with the limiting hole 5017, and the limiting hole 5017 is used to install a bolt abutting against the external wiring harness 5015.

[0051] The outer wall of the wiring head 5016 is provided with external threads and is used to be connected with the wiring connector 3 through the connecting sleeve 301, the inside of the case shell 1 is provided with a control mechanism, the control mechanism comprises a control screen 101 and a heat dissipation groove 1011, the control screen 101 is fixedly arranged at the front end of the case shell 1, and the heat dissipation groove 1011 is arranged on the outer wall of the case shell 1.

[0052] Working principle: the staff operates the fixing bolt 2011, the fixing bolt 2011 sequentially passes through the mounting holes 201 in the four corners of the inside of the back plate 2 and the mounting holes 201 in the four corners of the rear end of the case shell 1 from back to front, the back plate 2 and the case shell 1 are firmly connected into one through the threaded cooperation of the fixing bolt 2011 and the mounting hole 201, so as to guarantee the stability of the overall structure of the device and provide a stable installation foundation for the operation of subsequent parts; then the control terminal 2012 at the front end of the case shell 1 is started, after the control terminal 2012 is started, it immediately establishes electrical connection with the electric parts such as the tightening motor 2013, the stepping motor 4, the pressing push rod 3011 and the unfolding push rod 4014 in the device, sends initial detection signals to the parts, confirms that the parts are in a normal standby state, and provides control instruction transmission and data interaction support for subsequent stages of action.

[0053] When the wire harness butt joint preparation is needed, the control terminal 2012 sends a start instruction to the tightening motor 2013, and the tightening motor 2013 starts after receiving the instruction. The output shaft of the tightening motor 2013 starts to rotate and generates a driving force, which is directly transmitted to the output rod 2014 fixedly connected with the output shaft, driving the output rod 2014 to rotate synchronously. Since the extension rod 2015 is fixedly connected with one end of the output rod 2014, the rotation of the output rod 2014 will further drive the extension rod 2015 to rotate along its axis. When the extension rod 2015 rotates, the tightening wheel 2019 drives the connecting sleeve 301 to rotate inwards, and the guide groove 2016 formed on the outer wall of the connecting sleeve 301 cooperates with the four guide blocks 2018 fixedly arranged on the inner wall of the connecting sleeve 2017. The guide blocks 2018 slide in the guide groove 2016, which not only restricts the circumferential rotation freedom of the connecting sleeve 2017, but also guides the connecting sleeve 2017 to slide smoothly along the axis of the extension rod 2015. Since the tightening wheel 2019 is fixedly connected with one end of the connecting sleeve 2017, the sliding of the connecting sleeve 2017 and the rotation of the extension rod 2015 will jointly drive the tightening wheel 2019 to move axially and rotate circumferentially synchronously, so that the tightening wheel 2019 moves to a position close to the subsequent wire harness butt joint area, providing auxiliary power support for the subsequent tightening and fixing of the wire head 5016 and the wire harness connector 3.

[0054] After the tightening wheel 2019 is in place, the control terminal 2012 sends a turning and rotating speed instruction to the stepping motor 4. After receiving the instruction, the stepping motor 4 starts to rotate its output shaft at a set speed and direction, driving the drive gear 401 fixedly arranged on the outer wall of the output shaft to rotate synchronously. Since the drive gear 401 is located on the back side of the back plate 2 and is in meshing engagement with the guide tooth member 4012 arranged in an annular array on the outer wall of the support guide ring 4011, the rotation of the drive gear 401 will drive the guide tooth member 4012 through the tooth transmission, and then drive the support guide ring 4011 to rotate smoothly along the annular track in the annular groove formed on the back side of the back plate 2. When the support guide ring 4011 rotates, it will drive the four extension rails 4013 arranged in an annular array at one end of the support guide ring 4011 to rotate synchronously. By adjusting the orientation of the extension rails 4013, the extension rails 4013 can be aligned with the wire harness interfaces of different sampling devices, so as to adapt the position adjustment of the subsequent assembly mechanism to the wire harness layout requirements of different sampling devices.

[0055] After the extension guide rail 4013 is turned to the position, the control terminal 2012 sends a stretching instruction to the unfolding push rod 4014, the unfolding push rod 4014 is fixed in the sliding groove inside the extension guide rail 4013, and after receiving the instruction, the push rod body of the unfolding push rod 4014 extends or shrinks along the axis of the sliding groove; since the unfolding branch arm 4015 is fixedly connected with one end of the unfolding push rod 4014, and the unfolding branch arm 4015 is slidingly arranged in the extension guide rail 4013, the extension and contraction action of the unfolding push rod 4014 directly pushes or pulls the unfolding branch arm 4015 to move axially along the sliding groove of the extension guide rail 4013; when the unfolding branch arm 4015 moves, the support sleeve ring 5 fixedly connected therewith moves synchronously, the support sleeve ring 5 is of an annular structure, and the four guide rails 501 fixedly arranged in the annular structure inside the support sleeve ring 5 also adjust the front and back positions together with the support sleeve ring 5; the guide slider 5012 is slidingly arranged in the sliding groove inside the guide rail 501, and the guide slider 5012 is fixedly connected with the outer side of the bearing branch arm 5011, so that the movement of the guide rail 501 drives the bearing branch arm 5011 to move synchronously through the guide slider 5012, and finally makes the terminal block 5016 at one end of the bearing branch arm 5011 accurately move to a position aligned with the wire harness connector 3 at the rear end of the back plate 2, so as to ensure that the terminal block 5016 and the wire harness connector 3 can be accurately connected;

[0056] After the terminal block 5016 is aligned with the wire harness connector 3, the control terminal 2012 sends a pressing instruction to the pressing push rod 3011, the pressing push rod 3011 is fixed in the longitudinal groove at the rear end of the back plate 2, and after receiving the instruction, the push rod body of the pressing push rod 3011 extends downward along the longitudinal groove; the top end of the pressing push plate 3012 is fixedly connected with the bottom end of the pressing push rod 3011, and the pressing push plate 3012 is slidingly arranged in the longitudinal groove of the back plate 2, so that the extension action of the pressing push rod 3011 drives the pressing push plate 3012 to move towards the assembly mechanism, until one side of the pressing push plate 3012 is in close contact with the outer wall of the support sleeve ring 5, the support sleeve ring 5 is limited from shaking during the connection process by the pressing push plate 3012 applying transverse pressure on the support sleeve ring 5, and then the terminal block 5016 on the bearing branch arm 5011 is ensured to always be aligned with the wire harness connector 3, avoiding misalignment caused by vibration during connection;

[0057] After the pressure covering limiting position is completed, the control terminal 2012 controls the rotation of the connecting sleeve 301 (when the connecting sleeve 301 rotates, the friction generated between the connecting sleeve 301 and the outer wall of the connecting sleeve 301 drives the connecting sleeve 301 to rotate by the rotation of the tightening wheel 2019; when the connecting sleeve 301 is connected with the connecting head 5016, the inner thread of the connecting sleeve 301 rotates along the outer thread of the connecting head 5016, and at the same time, the distance between the connecting sleeve 301 and the connecting head 5016 becomes smaller until the connecting sleeve 301 is mostly sleeved on the outer wall of the connecting head 5016, so that the connecting sleeve 301 rotates while moving in a circular motion and rotates towards one side of the connecting head 5016), the connecting sleeve 301 is arranged on the outer wall of the wire harness connector 3 and is provided with an inner thread matched with the outer thread of the outer wall of the wire harness connector 3, and the outer wall of the connecting head 5016 is also provided with an outer thread, so that the connecting sleeve 301 is threadedly connected with the wire harness connector 3 and the connecting head 5016 when rotating, and the connecting head 5016 gradually approaches and is tightly connected with the wire harness connector 3 with the continuous rotation of the connecting sleeve 301, so as to realize the electrical conduction between the external wire harness 5015 and the control terminal 2012; at this time, the external wire harness 5015 is arranged in the through hole in the bearing arm 5011, and the worker installs a bolt in the limiting hole 5017 at one end of the bearing arm 5011, and after the bolt is tightened, one end of the bolt abuts against the outer wall of the external wire harness 5015 to fix the external wire harness 5015 in the through hole of the bearing arm 5011, so as to prevent the external wire harness 5015 from loosening or shifting during use and ensure the stability of data transmission;

[0058] When the wire harness needs to be replaced or disassembled, the control terminal 2012 first sends a reset command, the worker loosens the bolt in the limiting hole 5017, and the external wire harness 5015 is fixed; then the connecting sleeve 301 is rotated in the opposite direction, gradually separating from the threaded connection with the terminal 5016 and the wire harness connector 3, so that the terminal 5016 and the wire harness connector 3 are separated; then the rod body of the push rod 3011 is retracted, driving the push plate 3012 to return to the initial position along the transverse slot, and the push plate 3012 is retracted. The support sleeve 5 is pressed and positioned; the rod body of the expansion push rod 4014 is retracted, pulling the expansion arm 4015 along the sliding groove of the extension guide rail 4013 to move towards the support guide ring 4011, and the support sleeve 5, the guide rail 501, and the bearing arm 5011 also return to the initial position; the step motor 4 is reversely rotated, driving the drive gear 401 to reversely transmit, and the guide gear 4012 is reversely rotated, so that the support guide ring 4011 returns to the initial angle, and the extension guide rail 4013 also returns to the initial orientation; the tightening motor 2013 is reversely operated, the output shaft drives the output rod 2014 and the extension rod 2015 to reversely rotate, the connecting sleeve 2017 is retracted along the extension rod 2015 under the cooperation of the guide groove 2016 and the guide block 2018, and the tightening wheel 2019 is also reset; at the same time, one end of the spring rod 5013 is fixed to the bottom end of the guide block 5012, and the other end is fixed in the longitudinal slot of the guide rail 501. During the resetting of the bearing arm 5011, the spring rod 5013 releases the elastic potential energy, pushes the guide block 5012 along the longitudinal slot of the guide rail 501, and ensures that the bearing arm 5011 returns to the initial state completely, preparing for the next wire harness docking operation;

[0059] During the entire working process, the control mechanism inside the case shell 1 continuously operates, the control screen 101 is fixed to the front end of the case shell 1, and the worker can check the running state of each component, the wiring progress and the data transmission through the control screen 101, and send adjustment instructions to the control terminal 2012 according to the actual needs; the heat dissipation groove 1011 opened on the outer wall of the case shell 1 can timely discharge the heat generated during the operation of the device, avoid the failure of each component due to overheating, and ensure the long-term stable operation of the device;

[0060] If different types of sampling device wire harnesses need to be docked, different parameters can be set through the control screen 101, the control terminal 2012 will adjust the rotation angle of the step motor 4, the extension length of the expansion push rod 4014, and the rotation speed of the tightening motor 2013 according to the set parameters, so that the assembly mechanism can quickly adapt to the docking requirements of different wire harnesses, without frequent manual adjustment of component positions, greatly improving the efficiency and accuracy of wire harness docking;

[0061] After the stable docking of the terminal 5016 and the wire harness connector 3 is completed, and the external wire harness 5015 is fixed through the limiting hole 5017 of the bearing arm 5011 and the bolt, the device formally cuts into the core data collection link of the mountain photovoltaic disaster resistance simulation. At this time, the external wire harness 5015 fixed by the assembly mechanism can accurately connect the key monitoring equipment of the whole mountain photovoltaic power station, including the monitoring device for capturing extreme weather disaster signals, which can track sudden strong winds, concentrated rainfall, snow accumulation and other weather changes in the mountains in real time, and also includes the detection component for sensing geological risks, which can sensitively capture the subtle displacement of the soil on the slope and the abnormal change of the slope angle, and can also connect the equipment state monitoring components of the photovoltaic power station itself, and real-time master the stress and vibration of the photovoltaic panel, support and other core equipment in the complex environment;

[0062] The control terminal 2012 will rely on stable wire harness connection to centrally receive and orderly integrate these on-site information from different monitoring dimensions, and then synchronize the information to the mountain photovoltaic digital twin platform at a stable transmission rhythm according to the needs of disaster resistance simulation. These real scene data automatically collected by the device without manual operation interference are the basis for the digital twin platform to build accurate models. The platform can restore the terrain undulations, equipment layout density, and surrounding geological structure characteristics of the mountain photovoltaic power station according to these information, and then provide a "digital basement" that fits the actual situation for subsequent disaster simulation;

[0063] During the disaster resistance simulation process, the digital twin platform can accurately deduce the influence process of different disaster types on the power station based on the real on-site feedback transmitted by the device: for example, simulate how strong wind acts on photovoltaic supports in different slope areas, analyze how rainfall penetrates the soil to cause changes in slope stability, or judge the pressure transmission path of snow accumulation on photovoltaic components. The heat dissipation groove 1011 on the outer wall of the case shell 1 always maintains efficient heat dissipation to ensure that the core components such as the control terminal 2012, the stepping motor 4, and the tightening motor 2013 do not overheat during continuous data collection and transmission, and to ensure the stability of the entire data link, providing solid hardware support for continuous and reliable scene data required for disaster resistance simulation, and helping to accurately identify disaster hazards and develop scientific disaster resistance solutions in the future;

[0064] When the device completes all simulation operations, turn off the control terminal 2012, disconnect the power supply of each component, check whether each component is reset in place, and ensure that the device is in a safe standby state so that it can be quickly started next time.
