Description

Technical Field

[0001] This invention relates to the field of solar lighting tower technology, specifically a DC diesel engine hybrid solar lighting tower. Background Technology

[0002] Solar-powered lighting towers are widely used in open-air work areas such as construction sites, mining operations, and emergency rescue. However, solar-powered lighting towers have limited energy storage, and their energy storage is heavily dependent on weather conditions. In the face of sudden natural disasters and emergency rescue situations, the demand for lighting is enormous; the inability to provide illumination significantly increases the difficulty of rescue operations.

[0003] CN202423012911.4 discloses a hybrid energy lighting lighthouse that uses a diesel generator as a backup energy system. When solar energy is insufficient, the diesel generator operates to generate electricity and promptly charge the energy storage battery to provide stable and continuous power support, ensuring the reliability of the lighthouse's continuous operation.

[0004] However, during nighttime operations, small foreign objects often fall from heights at these work sites, such as concrete fragments, welding slag particles, or construction debris. Because the tempered glass surface of solar panels has limited impact resistance, it is highly susceptible to breakage if struck by a high-speed falling hard object, rendering the panel unusable. Therefore, this invention provides a DC diesel engine hybrid solar lighting tower. Summary of the Invention

[0005] The purpose of this invention is to provide a DC diesel engine hybrid solar lighting tower to solve the problem mentioned in the background art that the solar panels are easily damaged by foreign objects.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A DC diesel engine hybrid solar lighting tower includes a power supply vehicle, a lighting lamp, a mounting frame, multiple solar panels, a pair of protective covers, a transmission device, and two pairs of guide components. A lifting rod is fixedly connected to one vertical side of the power supply vehicle, and the lighting lamp is bolted to the lifting rod. Part of the upper side of the power supply vehicle is inclined towards another vertical side, and a fixing plate is fixedly connected to the upper part of the other vertical side of the power supply vehicle. Support legs are bolted to the non-inclined upper side of the power supply vehicle. Two pairs of sliding grooves are provided inside the mounting frame, with each pair of grooves slidably connected to a solar panel and bolted to the upper side of the mounting frame, respectively. The lower side of the mounting frame is bolted to the inclined surface of the power supply vehicle. A pair of protective covers cover the mounting frame and solar panels. The transmission device is located on the lower side of the mounting frame, with the transmission ends on both sides connected to the pair of protective covers, used to drive the pair of protective covers to rotate in opposite directions, thereby closing or opening the pair of protective covers. Each guide component is located at the connection between the transmission end and the protective cover, used to limit and guide the rotation of the protective cover.

[0008] Preferably, each protective cover has a U-shaped cross-section, and a pair of arc-shaped guide rods are provided at the corner of the lower side of the vertical part of the protective cover away from the fixing frame. The guide rods are located on the inner and outer sides of the vertical part of the protective cover. A limiting groove is also provided at the position of the fixing frame corresponding to the guide rod to match the guide rod located on the inner side of the side plate.

[0009] Preferably, the transmission device includes a motor bolted to the upper side of the fixed plate, a main rod, two pairs of directional components and a pair of transmission rod assemblies. One end of the main rod is fixedly connected to the motor, and the other end passes through the lower side of the fixed frame and extends further. Each pair of directional components is connected to each other, and both ends of any one of the directional components in each pair are connected to the main rod and the transmission rod assembly respectively.

[0010] Preferably, each directional assembly includes a directional ring, a gear, and a chain. The gear is fixedly connected to the side of the directional ring away from the motor. The chain is sleeved on the directional ring and one of the drive rod assemblies and engages for transmission. The directional ring of one of the directional assemblies in each pair is splinedly connected to the main rod.

[0011] Preferably, the transmission rod assembly is the transmission end of the transmission device; each transmission rod assembly includes a transmission rod, a pair of rotating rods and a pair of transmission rings. The transmission rod meshes with two corresponding chains for transmission. Both ends of the transmission rod are meshed with one end of the pair of transmission rings. One end of the pair of rotating rods is fixedly connected to the corresponding corner of the protective cover. The other end of the pair of rotating rods is meshed with the other end of the transmission rings, so that the transmission rings can slide along the rotating rods and the transmission rods. Fixing blocks are fitted on the outer walls of the transmission rods and the pair of rotating rods. The fixing blocks are bolted to the lower outer side of the fixing frame in the length direction.

[0012] Preferably, each guide assembly includes an inner plate and an outer plate bolted to the fixing frame, with the vertical portion of the protective cover located between the inner plate and the outer plate; the inner plate has an inner guide groove communicating with the limiting groove on the side facing the guide rod; the outer plate has an annular outer guide groove on the side facing the guide rod, so that the guide rods on the inner and outer sides of the vertical portion of the protective cover can rotate along the annular groove and the outer guide groove.

[0013] Preferably, a pair of support plates are bolted to the lower part of both sides of the outer panel; the support plate located on the inclined side of the power supply vehicle is bolted to the fixed plate, and one of the support plates is located on the lower side of the protective cover, providing support for the lower side of the protective cover in the closed state; the lower side of the support plate located on the side of the power supply vehicle away from the fixed plate is bolted to the upper end of the support leg.

[0014] Preferably, the inner plate is provided with an inner spring on the side away from the vertical part of the protective cover. The inner spring includes an inner rod with an L-shaped cross section and an inner spring. The horizontal part of the inner rod extends through the inner guide groove of the inner plate. The inner spring is located on the upper side of the horizontal part of the inner rod, and its two ends are fixedly connected to the opposite sides of the inner plate and the inner rod, respectively.

[0015] Preferably, the bottom side of the horizontal portion of the inner rod is flush with the bottom side of the vertical portion of the protective cover, and the upper end of the vertical portion of the inner rod extends further away from the inner plate with a rounded inner abutment portion. When the protective cover is fully opened, the solar panel slides out of the groove and abuts against the inner abutment portion, thereby pushing the inner rod to move. This causes the lower side of the horizontal portion of the inner rod to move to the end of the guide rod inside the protective cover, thereby restricting the rotation of the protective cover.

[0016] Preferably, support blocks are bolted to both sides of the fixed frame in the width direction. The two sides of the support blocks are arc-shaped sides that match the rounded corners of the side plates, which are used to support the protective cover after it is closed. A guide plate is also fixedly connected to the outside of the support block. A pair of symmetrical arc-shaped rotating grooves are opened on the inner side of the guide plate. A guide rod corresponding to the rotating groove is fixedly connected to the outside of the vertical part of each protective cover.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention, through the installation of a pair of protective covers, a transmission device, and a guiding assembly, allows the main rod and directional assembly to be driven by a motor during nighttime or non-working hours. This, via chain transmission, drives a pair of transmission rod assemblies to rotate in opposite directions, thereby causing the pair of protective covers to rotate towards each other until they are closed, completely enclosing the mounting frame and its solar panels. The protective panels and side plates of the protective covers form a U-shaped wrapping structure, effectively blocking falling debris such as concrete fragments, preventing the solar panels from breaking due to impact, extending their lifespan, and reducing maintenance and replacement costs. During normal daytime working hours, the motor drives the transmission device in the opposite direction, causing the pair of protective covers to rotate in the opposite direction until they are open, allowing the solar panels to be fully exposed to sunlight and ensuring normal photoelectric conversion efficiency.

[0019] The inner wall of the transmission ring is equipped with a rack, and the outer walls of the transmission rod and the rotating rod have corresponding grooves, allowing the transmission ring to slide axially along both. When the motor is operating normally, the transmission ring simultaneously engages the transmission rod and the rotating rod, achieving automatic transmission. When the motor malfunctions or manual operation is required, the transmission ring can be slid axially to disengage from the rotating rod, at which point the protective cover can be manually rotated. This simple operation improves usability in emergencies such as power outages or motor damage.

[0020] By installing guide rods on both the inner and outer sides of the protective cover's side panels, along with the inner guide groove on the inner plate, the annular outer guide groove on the outer plate, and the limiting groove on the fixing frame, a multi-guide structure is formed. During the rotation of the protective cover, the guide rods on the inner and outer sides slide along their corresponding guide grooves, while the guide rod on the outer side of the side panel rotates along the arc-shaped rotation groove on the guide plate. This ensures that the protective cover's movement trajectory is precise and its posture is stable during opening and closing, preventing skewing or jamming and improving operational reliability.

[0021] This invention incorporates locking mechanisms in both the open and closed states of the protective cover. In the open state, as the solar panel slides out of the chute, it abuts against the inner abutment part, pushing the inner rod laterally to the end of the inner guide rod, thus locking the protective cover in the open state. In the closed state, the magnets, when energized, attract each other, causing the locking rod to move and release the abutment from the outer abutment part. After power is cut off, the locking spring resets the locking mechanism, pushing the outer rod to the end of the outer guide rod, thus locking the cover in the closed state. This effectively prevents the protective cover from unexpectedly rotating under strong winds, vibrations, or other external forces, ensuring the safety of the equipment under various operating conditions.

Detailed Implementation

[0044] Example 1:

[0045] Please see Figures 1-21 The present invention provides a technical solution: such as Figures 1-2As shown, a DC diesel engine hybrid solar lighting tower includes a power supply vehicle 1, a lighting lamp 2, a mounting frame 3, multiple solar panels 4, a pair of protective covers 5, a transmission device 6, two pairs of guide components 7, and a pair of locking components 8. A lifting rod is fixedly connected to one vertical side of the power supply vehicle 1, and the lighting lamp 2 is bolted to the upper end of the lifting rod. Part of the upper side of the power supply vehicle 1 is inclined towards another vertical side, and a fixing plate 11 is fixedly connected to the upper part of the other vertical side of the power supply vehicle 1. The mounting frame 3 has two pairs of parallel sliding grooves 31 inside. Each pair of sliding grooves 31 and the upper side of the mounting frame 3 are respectively slidably connected to the solar panel 4 and bolted to the solar panel 4. The solar panel 4 can be slidably connected to the sliding groove 31 through a sliding rail. This is a conventional technical means and will not be described in detail. This allows the solar panel 4 to extend and retract from the sliding groove 31. Multiple fixing legs 32 are fixedly connected to the lower side of the mounting frame 3. The fixing legs 32 are bolted to the inclined side surface of the power supply vehicle 1, so that the mounting frame 3 remains parallel to the inclined side. A pair of protective covers 5 enclose the mounting frame 3 and the solar panel 4. A transmission device 6 is located on the lower side of the mounting frame 3. The transmission ends on both sides of the transmission device 6 are connected to the pair of protective covers 5 respectively, driving the pair of protective covers 5 to rotate in opposite directions, thereby closing or opening the pair of protective covers 5. Each guide component 7 is located at the connection between the transmission end and the protective cover 5, used to limit and guide the rotation of the protective cover 5, ensuring stable rotation. Locking components 8 are located on the mounting plate 11, used to lock the protective covers 5 in the closed state. The locking components 8 are located on both sides of the protective cover 5 in the width direction, locking the protective covers 5 in the closed state.

[0046] The power supply vehicle 1 is equipped with an energy storage battery and a diesel generator (not shown in the figure). Both the diesel generator and the solar panels 4 are electrically connected to the energy storage battery, which is in turn electrically connected to the lighting lamp 2 to provide power. If the solar panels 4 do not convert enough electricity, the diesel generator can generate power to supplement the energy storage battery, ensuring stable operation of the lighting lamp 2. Each solar panel 4 also has multiple heat sinks 41 installed on its underside to improve heat dissipation and enhance conversion efficiency during the daytime photovoltaic conversion. Multiple slots are provided on the upper and lowermost sliding groove walls of the mounting bracket 3 to facilitate the insertion of the heat sinks 41.

[0047] like Figure 2 and Figure 14As shown, each protective cover 5 includes a protective plate 51 and a pair of side plates 52. The pair of side plates 52 are located on both sides of the fixing frame 3 in the width direction, and the inner side of the side plates 52 is in contact with the fixing frame 3. The upper side of the pair of side plates 52 extends and is bolted to the protective plate 51 for easy maintenance. The lower corners of the opposite sides of the two side plates 52 on the same side are rounded to ensure that the opposite sides of the pair of protective covers 5 can fit together when closed, and the sum of the lengths of the two side plates 52 on the same side is greater than the width of the fixing frame 3 to reserve operating space for the connection between the side plates 52 and the transmission device 6. Rubber is also pasted on the opposite sides of the pair of protective plates 51 to ensure a sealing effect when closed and prevent liquid penetration. A pair of arc-shaped guide rods 53 are also provided at the corner of each side plate 52 away from the rounded corner. The pair of guide rods 53 are bolted to the inner and outer sides of the side plate 52 respectively. A limiting groove 33 is also provided in the fixing frame 3 at the position corresponding to the guide rod 53 to match the guide rod 53 located on the inner side.

[0048] like Figures 2 to 6 As shown, the transmission device 6 includes a motor 61, a main rod 62, two pairs of directional assemblies 63, and a pair of transmission rod assemblies 64. The motor 61 is bolted to the upper side of the fixing plate 11. One end of the main rod 62 is fixedly connected to the motor 61, and the other end passes through the fixing frame 3 and extends further to the horizontal side above the power supply vehicle 1. Each pair of directional assemblies 63 is connected to each other, and both ends of any one of the directional assemblies 63 are respectively connected to the main rod 62 and the transmission rod assembly 64. The transmission rod assembly 64 is the transmission end of the transmission device 6.

[0049] Each directional assembly 63 includes a directional ring 631, a gear 632, and a chain 633. The gear 632 is fixedly connected to the side of the directional ring 631 away from the motor 61. The chain 633 is sleeved on the directional ring 631 and one of the drive rod assemblies 64 and engages for transmission. The directional ring 631 of one of the directional assemblies 63 is splined to the main rod 62. The rotation of the main rod 62 drives the directional ring 631 and the gear 632 connected to it to rotate, thereby driving the gear 632 and the directional ring 631 of the other directional assembly 63 to rotate. Through the pair of directional rings 631, the corresponding pair of chains 633 are driven to rotate, thereby driving the corresponding pair of drive rod assemblies 64 to rotate. Each pair of directional components 63 is also provided with a limiting plate 65 on the side near the motor 61. The limiting plate 65 is bolted to the inner wall of the fixing frame 3 and fits against the corresponding pair of chains 633 to prevent the chains 633 from falling off the directional ring 631. The middle part of the limiting plate 65 is also rotatably connected to the main rod 62 to limit the position of the main rod 62 and ensure the stability of the main rod 62 when it rotates.

[0050] Each transmission rod assembly 64 includes a transmission rod 641, a pair of rotating rods 642, and a pair of transmission rings 643. The transmission rod 641 meshes with two corresponding chains 633 for transmission. Both ends of the transmission rod 641 are meshed with one end of the pair of transmission rings 643. One end of the pair of rotating rods 642 is fixedly connected to the corner of the corresponding side plate 52, and the other end of the pair of rotating rods 642 is meshed with the other end of the transmission rings 643. The transmission rings 643 and the transmission rods 641 are connected by toothed grooves and meshing with the rotating rods 642. Specifically, the inner wall of the transmission rings 643 is provided with multiple racks, and the corresponding transmission rods 641 and rotating rods 642 are provided with multiple grooves, so that the transmission rings 643 can slide axially along the transmission rods 641 and rotating rods 642. When the transmission rings 643 slide to the point of disengagement from the rotating rods 642, the protective cover 5 can be manually rotated, so that it can be manually flipped in case of motor 61 failure. The extension provided on the upper side of the side plate 52 can more conveniently control the flipping of the protective cover 5. A threaded ring 644 is rotatably connected to the side of the transmission ring 643 away from the guide rod 53. Correspondingly, a threaded groove is also provided on the side of the groove on the transmission rod 641 away from the rotating rod 642. When the transmission ring 643 is disengaged from the rotating rod 642, it is threadedly connected to the transmission rod 641 through the threaded ring 644, restricting the transmission ring 643 from sliding on its own. Fixing blocks 34 are fitted on the outer walls of both the transmission rod 641 and the pair of rotating rods 642. The fixing blocks 34 are bolted to the lower end of the fixing frame 3. The fixing blocks 34 on the rotating rod 642 are located between the side plate 52 and the groove to support the rotating rod 642 and ensure that the protective cover 5 can be manually flipped. Multiple fixing blocks 34 on the transmission rod 641 are arranged between a pair of threaded grooves.

[0051] like Figure 1 and 7 - Figure 12 As shown, each guide assembly 7 includes an inner plate 71 and an outer plate 72. The corner of each side plate 52 is located between the inner plate 71 and the outer plate 72. The inner plate 71 is bolted to the fixing frame 3. The inner plate 71 has a notch on the side facing the fixing frame 3 to match the fixing block 34, so that when the side of the inner plate 71 is connected to the fixing frame 3, the fixing block 34 is engaged in the notch. The inner plate 71 also has an inner guide groove 711 on the side facing the side plate 52. The inner guide groove 711 communicates with the limiting groove 33 to form an annular groove (see...). Figure 8The outer plate 72 facing the side plate 52 also has an annular outer guide groove 721 for matching guide rods 53, so that the guide rods 53 on the inner and outer sides of the side plate 52 can rotate simultaneously along the annular groove and the outer guide groove 721. A pair of support plates 111 are bolted to the lower part of both sides of the outer plate 72. The support plate 111 located on the inclined side of the power supply vehicle 1 is bolted to the fixed plate 11, and one of the support plates 111 is located on the lower side of the side plate 52, providing support for the lower side of the side plate 52 in the closed state. The support plate 111 located on the upper parallel side of the power supply vehicle 1 has a support leg 12 bolted to its lower side, and the support leg 12 is bolted to the parallel side of the power supply vehicle 1.

[0052] The inner plate 71 and the outer plate 72, on their sides away from the side plate 52, are respectively provided with an inner spring 712 and an outer spring 722. The inner spring 712 includes an inner rod 7121 with an L-shaped cross-section and an inner spring 7122 (see...). Figure 18 The inner rod 7121 extends horizontally to the inner guide groove 711 of the inner plate 71. The inner spring 7122 is located on the upper side of the horizontal portion of the inner rod 7121, and its two ends are fixedly connected to the opposite sides of the inner plate 71 and the inner rod 7121, respectively. The upper side of the horizontal portion of the inner rod 7121 has an arc-shaped groove that matches the inner spring 7122, preventing the inner spring 7122 from shifting outside the arc-shaped groove. The bottom side of the horizontal portion of the inner rod 7121 is flush with the lower side of the side plate 52, and the upper end of the vertical portion extends further away from the inner plate 71 with a rounded inner abutment portion 7123. When the protective cover 5 is fully opened, the solar panel 4 slides out from the slide groove 31 and abuts against the inner abutment portion 7123, thereby pushing the inner rod 7123 to move. This causes the lower side of the horizontal portion of the inner rod 7123 to move to the end of the guide rod 53 inside the side plate 52 (see Figure 20 This restricts the rotation of the protective cover 5, thereby locking the protective cover 5 in the open state.

[0053] The outer spring 722 includes an L-shaped outer rod 7221 and an outer spring 7222. The transverse portion of the outer rod 7221 extends through the outer guide groove 721 of the outer plate 72. The outer spring 7222 is located on the upper side of the transverse portion of the outer rod 7221, and its two ends are fixedly connected to the opposite sides of the outer plate 72 and the outer rod 7221, respectively. The upper side of the transverse portion of the outer rod 7221 also has an arc-shaped groove that matches the outer spring 7222, preventing the outer spring 7222 from shifting outside the arc-shaped groove. The side of the transverse portion of the outer rod 7221 facing the fixing frame 3 is flush with the vertical side of the side plate 52 where the guide rod 53 is provided. The upper end of the vertical portion extends further away from the outer plate 72 with a rounded outer abutment portion 7223. After the protective cover 5 is closed, pushing the abutment portion 7223 will drive the transverse portion of the outer rod 7221 to move, so that the transverse portion of the outer rod 7221 moves to the end of the guide rod 52 outside the side plate 52 (see Figure 17 This restricts the rotation of the protective cover 5 and locks the closed protective cover 5.

[0054] like Figure 14 As shown, support blocks 35 are bolted to both sides of the fixed frame 3 in the width direction. The two sides of the support blocks 35 are arc-shaped sides that match the rounded corners of the side plates, which are used to support the rounded corners of the side plates 52 after they are closed, so that the lower side of the side plates 52 remains parallel when closed. A guide plate 36 is also fixedly connected to the outside of the support blocks 35. A pair of symmetrical arc-shaped rotating grooves are opened on the inner side of the guide plate 36. A guide rod 54 corresponding to the rotating groove is fixedly connected to the outside of each side plate 52, so that the guide rod 54 can rotate along the rotating groove when the protective cover 5 rotates.

[0055] like Figure 15-21 As shown, each locking assembly 8 includes a positioning plate 81, a pair of locking rods 82, a pair of magnets 83, and a locking spring 84. The positioning plate 81 is bolted to the outside of the support block 35 and the guide plate 36. The two ends of the locking spring 84 are fixedly connected to one end of the pair of magnets 83, and the other ends of the pair of magnets 83 are fixedly connected to one end of the pair of locking rods 82. The pair of locking rods 82 and the pair of magnets 83 are arranged in the same direction and are slidably connected to the upper side of the positioning plate 81. The magnetic poles of the pair of magnets 83 are opposite at opposite ends. When energized, they generate magnetism and attract each other, thereby driving the pair of locking rods 82 to move towards each other and compressing the locking spring 84. When the power is off, the magnetism disappears, and under the stretching action of the locking spring 84, the pair of locking rods 84 and the pair of magnets 83 move in opposite directions. The magnets 83 are electrically connected to the energy storage battery in the power supply vehicle 1. The other end of the locking rod 82 is used to abut against the outer abutment part 7223. When the locking rod 82 moves in the opposite direction, it pushes the outer abutment part 7223 and the outer rod 7221 to move, and abuts against the guide rod 53 on the outside of the side plate 52. An outer limit block 811 and an inner limit block 37 are also fixedly connected to both sides of the positioning plate 81 and both sides of the fixing frame 3 along the length direction, respectively. The outer limit block 811 and the inner limit block 37 extend to the lower side of the outer abutment part 7223 and the lower side of the inner abutment part 7123, respectively, to restrict the movement path of the outer rod 721 and the inner rod 712, and prevent them from disengaging from the corresponding outer rod 71 and inner plate 71.

[0056] The motor 61 is also configured to rotate after a short delay following power-on, so that the magnet 83 can acquire magnetism during the power-on period before startup, thereby driving the locking rod 82 to move until it disengages from the outer contact part 7223. Controlling the presence or absence of magnetism by whether the magnet 83 is energized and the delayed rotation of the motor 61 after power-on are both conventional technical means, which will not be elaborated here. The delay time of the motor 61 can be set to be slightly longer than the time it takes for the locking rod 82 to disengage from the outer contact part 7223.

[0057] like Figure 16 and Figure 21 As shown, two pairs of limiting components 9 are also provided. When the power is off, they replace the function of a pair of magnets 83 moving a pair of locking rods 82 toward each other when the power is on, thereby disengaging from the contact with the outer contact part 7223.

[0058] A pair of limiting components 9 are provided on each pair of support legs 12 and fixed plate 11, with each limiting component 9 located near the corresponding outer plate 72. Each limiting component 9 includes a limiting rod 91, a rotating rod 92, and a positioning block 93. The limiting rod 91 is bolted to the fixed plate 11 or support leg 12, and one end of the rotating rod 92 is rotatably connected to the upper end of the limiting rod 91. A positioning block 93 is bolted to each locking rod 82. In the natural state of the locking spring 84, the positioning block 93 is located on the side of the rotating rod 92 away from the locking spring 84. When the power is off, the locking rod 82 can be manually moved towards the locking spring 84 to disengage from the outer abutment part 7223. Then, the rotating rod 92 can be rotated to make the rotating rod 92 engage with the positioning block 93 on the side away from the locking spring 84 (see...). Figure 15 This prevents the locking lever 82 from automatically moving in the opposite direction and re-engaging with the external ground connection 7223. After that, the protective cover 5 can be rotated to open the cover over the solar panel 4.

[0059] Working principle: When the protective cover 5 needs to be opened during the day, the operator starts the motor 61, and the magnets 83 are simultaneously energized. Before the drive end of the motor 61 rotates, the lock on the outer guide rod 53 of the side plate 52 is automatically released. The specific process is as follows: After each pair of magnets 83 is energized, they attract each other, thereby driving a pair of locking rods 82 to move towards each other. At the same time, the locking spring 84 is compressed until the other end of the locking rod 82 moves to the point where it disengages from the outer contact part 7223. At this time, under the tension of the outer spring 722, the lateral part of the outer rod 721 is pushed to move away from the outer plate 72, so that the lateral part of the outer rod 721 disengages from the contact with the end of the outer guide rod 53 of the side plate 52, thereby releasing the lock on the protective cover 5.

[0060] Then, motor 61 starts, and the drive end of motor 61 drives the main rod 62 to rotate. The main rod 62 drives two pairs of directional rings 631, two pairs of gears 632, and two pairs of chains 633 to rotate in opposite directions. This, in turn, drives a pair of transmission rods 641, a pair of transmission rings 643, and a pair of rotating rods 642 to rotate in opposite directions through the two pairs of chains 633. This, in turn, drives a pair of protective covers 5 to rotate in opposite directions, opening the cover on the solar panel 4. During the rotation of the protective cover 5, the guide plates 53 on the inner and outer sides of the side plate 52 rotate along the corresponding inner guide groove 711 and outer guide groove 721, respectively. At the same time, the guide plates 54 on the inner and outer sides of the side plate 52 rotate along the corresponding rotating groove, ensuring the stability and reliability of the rotation when the protective cover 5 is opened. When the protective cover 5 rotates to the point where its side is in contact with the sides of the power supply vehicle 1, motor 61 is turned off. At the same time, the power supply to magnet 83 is turned off, magnet 83 loses its magnetism, and under the tension of spring 84, it pushes the locking rod 82 to reset.

[0061] Finally, the operator pulls the solar panel 4 out from the slide 31 to both sides. During the process of pulling out the solar panel 4, the side of the solar panel 4 in the width direction will abut against the inner abutment part 7123, thereby pushing the transverse part of the inner rod 7121 to move laterally to the end of the guide rod 53 inside the side plate 52, and locking the opened protective cover 5.

[0062] When the solar panel 4 is retracted, the operator first pushes the solar panel 4 into the slide groove 31. During the movement, the solar panel 4 will gradually disengage from the contact with the inner abutment part 7123. Then, under the stretching elasticity of the inner spring 7122, the horizontal part of the inner rod 7121 is pushed to move away from the inner plate 71 until the inner rod 7121 disengages from the contact with the inner guide rod 52 of the corresponding side plate 52.

[0063] Then, the motor 61 is started, and the magnet 83 is energized at the same time. The magnet 83 regains its magnetism and drives a pair of locking rods 82 to move towards each other until the lateral part of the outer rod 721 disengages from the end of the guide rod 53 on the outer side of the side plate 52. Then the motor 61 starts and drives the main rod 62 to rotate in the opposite direction, eventually driving a pair of protective covers 5 to rotate towards each other until the protective plates 51 of the pair of protective covers 5 are in contact with each other on opposite sides. The guide rod 54 then rotates into the corresponding rotating groove again.

[0064] Finally, the motor 61 is turned off, and the magnet 83 is de-energized. The locking rod 82 is pushed to reset, so that the outer abutment part 7223 abuts against the end of the guide rod 53 on the outer side of the corresponding side plate 52, thus locking the protective cover 5.

[0065] If the motor 61 cannot rotate, the protective cover 5 can be rotated manually. The specific operation is as follows: When closing, the operator first manually controls the locking rod 82 to move toward the locking spring 84 until the outer abutment part 7223 disengages from the abutment of the end of the guide rod 53 on the outer side of the corresponding side plate 52. Then, rotate the rotating rod 92 until the positioning block 93 moves away from the side of the locking spring 84, thus restricting the reverse movement of the locking rod 82.

[0066] Then the operator controls the transmission ring 643 to slide towards the transmission rod 61, so that the transmission ring 643 is disengaged from the rotating rod 642. Then the threaded ring 644 is rotated to connect with the transmission rod 61, restricting the transmission ring 643 from sliding downward. At this time, the protective cover 5 can be rotated to close.

[0067] After the protective cover 5 is closed, the rotating rod 92 is rotated in the opposite direction to disengage from the positioning block 93. Under the stretching elasticity of the locking spring 84, the locking rod 82 moves toward the outward abutment part 7223, thereby locking the protective cover 5.

[0068] If maintenance is required on the solar panel 4, especially the solar panel 4 on the upper side of the mounting bracket 3, the protective plate 51 and the side plate 52 can be removed to observe the operating status of the solar panel 4 through the inside of the power supply vehicle 1, so as to facilitate maintenance work; this avoids the inability to open the inside of the power supply vehicle 1 after the protective cover 5 is opened.
