Description

Technical Field

[0001] This invention belongs to the field of agricultural facilities and photovoltaic energy integration technology, specifically involving a photovoltaic greenhouse that integrates photovoltaic, planting and breeding. Background Technology

[0002] A photovoltaic greenhouse is a new type of agricultural facility that deeply integrates photovoltaic power generation technology with agricultural planting and breeding activities. Its core is to lay photovoltaic modules (solar panels) on the top or sides of the greenhouse. Under the premise of ensuring the normal operation of agricultural production (planting, breeding, edible fungi cultivation, etc.), it realizes solar power generation, taking into account multiple needs of energy production, agricultural output and ecological environmental protection.

[0003] The transpiration of crops, irrigation, and the respiration and waste disposal of livestock all continuously release large amounts of water vapor into the greenhouse air. Furthermore, due to diurnal or seasonal temperature differences, the low temperature outside the greenhouse lowers the temperature of the roof and walls. When the warm, humid air inside the greenhouse comes into contact with the low-temperature surfaces, it condenses into water droplets, resulting in condensation. Because the sides of the greenhouse are vertical, the condensed water vapor quickly slides off. However, due to the small angle of inclination at the top, the condensed water vapor remains on the roof for a longer period, increasing the likelihood of water vapor entering the photovoltaic modules. If water vapor seeps into the photovoltaic modules, it can easily cause short circuits, module aging, and shorten the lifespan of the photovoltaic equipment. Current technology uses a sealing film on the lower surface of the photovoltaic modules to prevent water vapor from entering, but water vapor and droplets clinging to the sealing film create a persistently high humidity environment inside the greenhouse, affecting plant growth. Summary of the Invention

[0004] This invention provides a photovoltaic greenhouse that integrates photovoltaics, planting, and aquaculture, solving the technical problem in related technologies where water vapor condenses and hangs on the inner walls of the greenhouse, resulting in a continuously high humidity state that affects plant growth.

The first limiting block is located on one side of the second limiting block. A scraper is fixedly installed on the side of the first limiting block.

[0012] In a preferred embodiment, an extension rod is provided at the end of the third contact plate. When the third contact plate moves obliquely downward, it pushes the plumb rod through the extension rod to change the angle between the plumb rod and the water receiving plate. A reinforcing plate is provided between the rectangular frame and the first contact plate. The reinforcing plate is slidably connected to the extension rod, and a limit groove is provided at the junction of the reinforcing plate and the extension rod.

[0013] In a preferred embodiment, the photovoltaic module is slidably connected to the supporting frame. The mounting plate has a strip-shaped hole inside, and a disc-shaped cavity is provided in the middle section of the strip-shaped hole.

The present invention uses a stepped condensation surface composed of a first contact plate, a second contact plate and a third contact plate to capture, direct, and recycle water vapor in the greenhouse without relying on high-energy-consuming ventilation equipment. This not only avoids the corrosion of photovoltaic modules by water vapor retention and extends their service life, but also effectively regulates the humidity of the planting and breeding area and reduces the occurrence of diseases and epidemics.

[0016] 2. The water control mechanism of this invention quickly absorbs the condensed water scraped off by the contact plate through the first and second water-absorbing blocks to achieve temporary storage. At the same time, it closely fits the surfaces and gaps of adjacent contact plates to form a dynamic seal, preventing water leakage and spillage. The collection mechanism is located on the side of the greenhouse and does not occupy the core space for planting and breeding. It can rotate in a direction under the drive of the third contact plate to concentrate the collected water and pour it to the edge of the greenhouse, avoiding affecting normal planting and breeding.

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1 like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a photovoltaic greenhouse integrating photovoltaic, planting, and breeding functions includes a greenhouse body 1, photovoltaic modules 2 slidably installed on the top of the greenhouse body 1, a surrounding panel 3 fixedly installed on the bottom of the greenhouse body 1, and support columns 4 fixedly installed at the corners of the surrounding panel 3. A water vapor collection mechanism 5 is fixedly connected to the lower surface of the photovoltaic module 2. The water vapor collection mechanism 5 includes a rectangular frame 51, a first contact plate 52, a second contact plate 53, and a third contact plate 54. A mounting connection plate 57 is fixedly installed on the top of the rectangular frame 51. The mounting connection plate 57 is attached to the bottom of the photovoltaic module 2, and the two are kept in a relatively static connection state by friction. Plate 52 is set at the bottom of rectangular frame 51, and the first contact plate 52 is set in an inclined state. The second contact plate 53 slides against the upper surface of the first contact plate 52, and the third contact plate 54 slides against the upper surface of the second contact plate 53. In use, the second contact plate 53 and the third contact plate 54 slide along the length direction of the first contact plate 52. After unfolding, the lower surfaces of the first contact plate 52, the second contact plate 53, and the third contact plate 54 form a stepped condensation surface for contacting water vapor. After the water vapor condenses on the condensation surface, the water on the condensation surface is scraped off by moving the second contact plate 53 and the third contact plate 54 at regular intervals.

[0031] In this embodiment, the specific implementation scenario is as follows: the main body 1 of the greenhouse, the surrounding panels 3, and the supporting columns 4 together form a stable enclosed planting and breeding space. The photovoltaic module 2 is installed on the top of the greenhouse through the water vapor collection mechanism 5 to realize the conversion of solar energy into electrical energy. Its lower surface is fixedly connected to the mounting connection plate 57 to ensure its structural stability. The rectangular frame 51 determines the height and angle of the first contact plate 52 and provides movement space for the second contact plate 53 and the third contact plate 54. The first contact plate 52 is fixed to the bottom of the rectangular frame 51 and is in an inclined state. The second contact plate 53 slides against the upper surface of the first contact plate 52, and the third contact plate 54 slides against the upper surface of the second contact plate 53. The two are along the first contact plate 52. After sliding out along its length, the plate 52 and the first contact plate 53 together form a stepped condensation surface. The stepped condensation surface consists of the lower surface and end face of the first contact plate 52, the second contact plate 53, and the third contact plate 54. After water vapor condenses on this condensation surface, the second contact plate 53 is driven by the third contact plate 54 at regular intervals. During the movement, the relative displacement between the third contact plate 54 and the second contact plate 53, and the relative displacement between the second contact plate 53 and the first contact plate 52, are used to scrape off the water on the lower surface of the plate, thereby completing the initial collection of water vapor. After the water is scraped off, the second contact plate 53 and the third contact plate 54 are re-expanded, which can continue to maintain the efficient function of separating water vapor.

[0032] It should be noted that, compared to a traditional flat surface, the stepped condensation surface has three additional end faces of the first contact plate 52, the second contact plate 53, and the third contact plate 54. This increases the water vapor contact area and improves condensation efficiency. Compared to a single flat condensation surface, the stepped structure forms a multi-tiered bearing surface through height differences. Within the limited space at the top of the greenhouse, it can more effectively capture the warm and humid air inside, allowing water vapor to quickly condense into water droplets on the lower and end faces of each contact plate. The water droplets on the end faces will slide down to the lower surface. Furthermore, the stepped structure provides space for subsequent scraping of condensed water, ensuring that the second contact plate 53 and the third contact plate 54 have sufficient space to move. By moving the second contact plate 53 and the third contact plate 54, the condensed water can be scraped off, keeping the condensation surface clean and facilitating continuous water vapor condensation. At the same time, it also avoids the situation where water droplets randomly drip onto crop leaves or the breeding area, which is common in flat structures.

[0033] It should also be noted that, such as Figure 2 As shown, a support plate 7 is fixedly installed in the middle section of the inner wall of the greenhouse body 1. The area below the support plate 7 is the breeding area, which is used to raise animals. Multiple planting racks 8 are fixedly installed at equal intervals on the upper surface of the support plate 7. The planting racks 8 are the planting area. The support plate 7 can separate animals from plants to prevent animals from eating plants. A support rod 9 is fixedly connected to the lower surface of the support plate 7. The support rod 9 is used to improve the stability of the support plate 7 and ensure that people can walk normally on the support plate 7. The two sides of the support plate 7 are fixedly connected to the top support frame 6. The top support frame 6 is fixedly connected to the lower surface of the mounting connection plate 57. The top support frame 6 is used to help reinforce the greenhouse body 1 and the water vapor collection mechanism 5.

[0034] like Figure 5 and Figure 9 As shown, the bottom of the first contact plate 52 is integrally formed with an agglomerating plate 55. The agglomerating plate 55 has a flow guiding cavity 514 inside. The flow guiding cavity 514 is located at the junction of the first contact plate 52 and the agglomerating plate 55. The opening of the water inlet of the flow guiding cavity 514 faces the second contact plate 53, and the opening of the water outlet of the flow guiding cavity 514 faces the side of the greenhouse. A collection component 56 is provided at the water outlet of the flow guiding cavity 514, and a water control mechanism 58 is provided at the water inlet of the flow guiding cavity 514.

[0035] The gathering plate 55 serves as a transitional carrier for water vapor collection. Its internal guiding cavity 514 is located below the first contact plate 52. When scraping off condensed water, the guiding cavity 514 acts as a directional water transport channel. The opening of the water inlet of the guiding cavity 514 faces the second contact plate 53, allowing the scraped water droplets to flow directly into the guiding cavity 514. The water control mechanism 58 at the water inlet buffers and intercepts the water flow into the guiding cavity 514, preventing a large amount of water from concentrating and dripping onto the plants below. The water outlet of the guiding cavity 514 faces the side of the greenhouse. Using gravity and the guiding effect of the channel, water is guided from the core area of ​​the greenhouse to the collection component 56 on the side of the greenhouse, thus completing the final recovery of water vapor. The entire process does not interfere with planting and cultivation activities and avoids uneven humidity distribution caused by water flowing randomly within the greenhouse. Overall, it ensures the high efficiency of water vapor collection and avoids the adverse effects of water backflow or random scattering on the photovoltaic module 2 and the planting and cultivation environment.

[0036] Example 2 like Figure 4 , Figure 5 and Figure 9 As shown, the collecting component 56 includes a water receiving plate 561 and a vertical rod 562 integrally formed on one side of the water receiving plate 561. The water receiving plate 561 is located at the bottom end of the vertical rod 562 and is lower than the outlet of the guide cavity 514. The angle between the water receiving plate 561 and the vertical rod 562 is between 75° and 85°. One end of the vertical rod 562 is rotatably connected to the lower surface of the mounting connecting plate 57. A drain hole 565 is provided at a corner inside the water receiving plate 561. A hollow cylinder 563 is rotatably connected to one side of the vertical rod 562. A connecting block 564 is connected inside the hollow cylinder 563 by a spring. One end of the connecting block 564 is rotatably connected to the mounting connecting plate 57. The hollow cylinder 563, the connecting block 564 and the vertical rod 562 form a Y-shaped structure to elastically limit the angle of the water receiving plate 561.

[0037] It should be noted that the hollow cylinder 563 and the connecting block 564 are connected by a spring. The spring is initially in a stretched state to push against the vertical rod 562. When the second contact plate 53 and the third contact plate 54 are in the unfolded state, the vertical rod 562 is in a vertical or nearly vertical state, the drain hole 565 is facing upwards at an angle, and the water receiving plate 561 is held below the outlet of the guide cavity 514. When the second contact plate 53 and the third contact plate 54 are in the unfolded state, they are used to receive water that slides off the lower surface of the collecting plate 55. The upward-facing drain hole 565 can prevent water from flowing out of the drain hole 565, effectively preventing water from flowing out. The water-stopping beads fall directly into the soil below for planting, ensuring that the soil moisture is not affected. When the second contact plate 53 and the third contact plate 54 are in the retracted state, the angle of the plumb rod 562 changes. The third contact plate 54 pushes the plumb rod 562 to rotate to the side of the greenhouse. At this time, due to the angle between the plumb rod 562 and the water receiving plate 561, water in the water receiving plate 561 will only flow into the drain hole 565 after the plumb rod 562 drives the water receiving plate 561 to rotate a large angle. At this time, since the water receiving plate 561 is already in an inclined state, the side wall of the drain hole 565 also remains in an inclined state. Figure 9 As shown, the tilt of the water receiving plate 561 will cause the drain hole 565 to rotate from its original state facing the inside of the greenhouse to its state facing the side wall of the greenhouse. Therefore, the water will eventually slide down the side wall of the drain hole 565 and fall to the edge of the greenhouse.

[0038] The collecting component 56 is located at one end of the rectangular frame 51 near the side of the shed, avoiding occupying the core space for planting and breeding. The overall height of the water receiving plate 561 is lower than the outlet of the guide cavity 514. The height difference ensures that the water can drip naturally into the water receiving plate 561. One end of the plumb rod 562 is rotatably connected to the lower surface of the mounting connecting plate 57 to determine the rotation center of the water receiving plate 561. During the rotation of the plumb rod 562, the spring between the hollow cylinder 563 and the connecting block 564 will be compressed. Subsequently, when the third contact plate 54 leaves the plumb rod 562, the spring rebound will push the plumb rod 562 to a vertical state.

[0039] Example 3 like Figure 6 and Figure 8As shown, the water control mechanism 58 includes a first water-absorbing block 581 and a second water-absorbing block 582. The first water-absorbing block 581 is fixedly installed at the end of the first contact plate 52, and the edge of the first water-absorbing block 581 is in contact with the lower surface of the second contact plate 53. The second water-absorbing block 582 is fixedly installed on the end face of the second contact plate 53, and the edge of the second water-absorbing block 582 is in contact with the lower surface of the third contact plate 54. A push rod 586 is fixedly installed at the end of the third contact plate 54. Positioning blocks 585 are provided on both sides of one end of the 3. A guide rod 584 is inserted into the inside of the positioning block 585. A squeezing plate 583 is fixedly installed at the end of the guide rod 584. The squeezing plate 583 is located on one side of the second water-absorbing block 582. When the third contact plate 54 moves diagonally downward, it pushes the squeezing plate 583 to squeeze the second water-absorbing block 582 through the push rod 586. When the second contact plate 53 moves diagonally downward, it squeezes the first water-absorbing block 581 through the squeezing plate 583, so that water flows into the guide cavity 514.

[0040] It should be noted that the first water-absorbing block 581 is located on the end face of the first contact plate 52 facing the guide cavity 514, the second water-absorbing block 582 is located on the end face of the second contact plate 53 facing the guide cavity 514, the push rod 586 is located at the end of the third contact plate 54 facing the ceiling, and the positioning blocks 585 are located on both sides of the second contact plate 53 facing the ceiling. The water control mechanism 58 absorbs the scraped water through the first water-absorbing block 581 and the second water-absorbing block 582. Both the first water-absorbing block 581 and the second water-absorbing block 582 are made of highly elastic water-absorbing sponge material. The highly elastic water-absorbing sponge material can quickly absorb the water scraped from the stepped condensation surface and fill the gaps between adjacent plates to prevent moisture from spreading. The system allows for temporary storage and sealing to prevent leakage of water through gaps. When the third contact plate 54 moves diagonally downwards, the second contact plate 53 slides synchronously. After the second contact plate 53 stops moving, the third contact plate 54 continues to move. Eventually, the push rod 586 at the end of the third contact plate 54 pushes the extrusion plate 583 to slide along the guide rod 584, thereby extruding the second absorbent block 582 and squeezing out the water it has absorbed. The guide rod 584 is slidably set on the back of the positioning block 585. Subsequently, as the third contact plate 54 continues to move, the extrusion plate 583 further extrudes the first absorbent block 581. The water squeezed out from the first absorbent block 581 and the second absorbent block 582 flows directly into the guide cavity 514.

[0041] Example 4 like Figure 7 , Figure 8 and Figure 9As shown, a motor lead screw drive assembly 59 is fixedly installed on the inner side of the rectangular frame 51. The lead screw of the motor lead screw drive assembly 59 is rotatably connected to the edge of the rectangular frame 51. A connecting piece is provided on the upper surface of the third contact plate 54 and threadedly connected to the motor lead screw drive assembly 59. Second limiting blocks 512 are provided on both sides of the third contact plate 54, and first limiting blocks 511 are provided on both sides of the other end of the second contact plate 53. The first limiting blocks 511 are located on one side of the second limiting blocks 512. A scraper 510 is fixedly installed on the surface, and the scraper 510 surrounds the lower surface of the collecting plate 55. An extension rod 513 is provided at the end of the third contact plate 54. When the third contact plate 54 moves obliquely downward, it pushes the vertical rod 562 through the extension rod 513 to change the angle between the vertical rod 562 and the water receiving plate 561. A reinforcing plate 515 is provided between the rectangular frame 51 and the first contact plate 52. The reinforcing plate 515 is slidably connected to the extension rod 513, and a limit groove 516 is provided at the junction of the reinforcing plate 515 and the extension rod 513.

[0042] It should be noted that the second limiting block 512 is located on both sides of the third contact plate 54 near the side end of the greenhouse, the first limiting block 511 is located on both sides of the second contact plate 53 near the side end of the greenhouse, the extension rod 513 is located at the end of the third contact plate 54 near the side end of the greenhouse, the reinforcing plate 515 is located at the end of the rectangular frame 51 near the side end of the greenhouse, and the motor screw drive assembly 59, as the power source for driving the second contact plate 53 and the third contact plate 54, is located above the third contact plate 54, specifically inside the rectangular frame 51, and will not come into contact with the water vapor below. When the motor drives the screw to rotate, it drives the third contact plate 54 along the rectangular frame 51. The inclined trajectory of 1 moves obliquely upward. When the second limiting block 512 on the side of the third contact plate 54 contacts the positioning block 585 on the side of the second contact plate 53, the guide rod 584 will be pushed out, so that the squeezing plate 583 is away from the first water-absorbing block 581 and the second water-absorbing block 582. During the continuous movement of the third contact plate 54, the positioning block 585 will be pushed by the second limiting block 512 to achieve the purpose of driving the second contact plate 53. Finally, the second contact plate 53 and the third contact plate 54 are fully unfolded. Throughout the process, the second limiting block 512 always fits against the side of the second contact plate 53, which can prevent the second contact plate 53 from being misaligned or falling off.

[0043] It should also be noted that when the motor screw drive assembly 59 drives the third contact plate 54 to move diagonally downward, it loses the restriction of the second limit block 512, and the second contact plate 53 will slide diagonally downward simultaneously. During this process, the relative sliding between the second contact plate 53 and the first contact plate 52 can scrape off the condensed water on the lower surface of the second contact plate 53. Furthermore, during the movement of the second contact plate 53, the scraper 510 located on the side of the first limit block 511 will simultaneously scrape off the condensed water on the lower surface of the first contact plate 52. After the second contact plate 53 stops sliding, the relative sliding between the third contact plate 54 and the second contact plate 53 will scrape off the condensed water on the lower surface of the third contact plate 54.

[0044] The extension rod 513 at the end of the third contact plate 54 and the vertical rod 562 are located on the same vertical plane. When the third contact plate 54 moves obliquely downward, the extension rod 513 will push the vertical rod 562 to rotate around the mounting connecting plate 57, thereby changing the tilt angle of the water receiving plate 561 to achieve the purpose of pouring water. The reinforcing plate 515 provides sliding support for the extension rod 513, and the limiting groove 516 at its junction limits the movement trajectory of the extension rod 513.

[0045] Example 5 like Figure 10 and Figure 11 As shown, the photovoltaic panel is opaque, blocking sunlight during the day, preventing the plants from receiving direct sunlight. Consequently, the plants in the greenhouse rely on artificial light for illumination both day and night, and the electricity generated by the photovoltaic panel is insufficient to support 24-hour lighting. To ensure that the plants receive sufficient light, this application further provides the following technical solution.

[0046] Specifically, the photovoltaic module 2 is slidably connected to the supporting frame 6. A strip-shaped hole 517 is provided inside the mounting connecting plate 57. A disc-shaped cavity 518 is provided in the middle section of the strip-shaped hole 517. A limit rod 519 is rotatably connected to the lower surface of the photovoltaic module 2. The shape of the end face of the limit rod 519 matches the inner wall of the disc-shaped cavity 518, and the width of the limit rod 519 matches the strip-shaped hole 517. The limit rod 519 passes through the strip-shaped hole 517. A servo motor 521 is fixedly installed on the lower surface of the end of the photovoltaic module 2. A driven rod 522 is rotatably installed inside the limit rod 519. Both the driven rod 522 and the output end of the servo motor 521 are provided with bevel gears. A bevel gear meshes with the limiting rod 519, which has an internal cavity 520. The end of the cavity 520 has a fan-shaped opening. The output shaft of the servo motor 521 is located inside the fan-shaped opening of the cavity 520. The limiting rod 519 has an internal guiding cavity 524. A turntable 525 is rotatably mounted at the center of the guiding cavity 524. The turntable 525 is fixedly connected to the end of the driven rod 522. Positioning rods 523 are slidably mounted at both ends of the guiding cavity 524. A slot is provided on the side wall of the disc-shaped cavity 518. The shape of the slot is adapted to the positioning rod 523. An arc-shaped transmission rod 526 is rotatably connected between the positioning rod 523 and the edge of the turntable 525.

[0047] It should be noted that the photovoltaic module 2 is slidably connected to the support rod 9, ensuring the stability of the photovoltaic module 2. The strip hole 517 in the mounting plate 57 cooperates with the limiting rod 519 on the lower surface of the photovoltaic module 2, restricting the movement path of the photovoltaic module 2. Furthermore, a positioning rod 523 for locking its own position is set inside the limiting rod 519. The bracket for mounting the servo motor 521 is located at the end of the strip hole 517. When the photovoltaic module 2 is at the top of the greenhouse, the end of the third contact plate 54 abuts against the side of the limiting rod 519, and the positioning rod 523 is inserted into the slot on the side wall of the disc-shaped cavity 518. At this time, the entire greenhouse is in a closed state, which can effectively prevent the greenhouse environment from being affected by the external low temperature. At the same time, the photovoltaic module 2 is the lighting equipment and its... He uses electrical equipment for power supply. Water vapor in the air inside the greenhouse condenses into water droplets on the surfaces of the first contact plate 52, the second contact plate 53, and the third contact plate 54 after cooling. During water scraping, the photovoltaic module 2 remains locked in place with the cooperation of the limit rod 519 and the positioning rod 523. At this time, the third contact plate 54 can retract normally to clean up the water collected overnight. After completing one retraction action, the third contact plate 54 re-expands, and its end face re-abuts against the limit rod 519. When it is sunny during the day, the photovoltaic module 2 performs photovoltaic power generation normally. When the plants need to receive direct sunlight, the servo motor 521 is first started. The servo motor 521 engages with the driven rod 522 through a bevel gear. During the rotation of the driven rod 522, its top... The turntable 525 at the end will pull the positioning rod 523 out of the slot through the arc-shaped transmission rod 526, thus unlocking the limit rod 519. When the inner side of the arc-shaped transmission rod 526 is in contact with the edge of the turntable 525, the positioning rod 523 stops moving. At this time, the rotation of the turntable 525 will act on the entire limit rod 519 through the positioning rod 523, causing the limit rod 519 to rotate. The angle of the fan-shaped opening of the cavity 520 is between 120° and 145°. During the rotation of the limit rod 519, the transmission between the servo motor 521 and the driven rod 522 will not be affected. When the limit rod 519 rotates to align with the strip hole 517, the third contact plate 54 begins to retract, cleaning up the moisture collected overnight, and at the same time releasing the limit rod. When the support rod 519 is in its limiting position, the photovoltaic module 2, having lost the support of the third contact plate 54, will slide diagonally downwards along the surface of the mounting plate 57 under the influence of gravity, thus exposing the top of the greenhouse to allow the plants to receive natural sunlight. The photovoltaic module 2 will stop supplying power to the greenhouse lighting and other electrical equipment. In rainy or cold weather, the servo motor 521 will not be activated; instead, the third contact plate 54 will retract to process the collected moisture. The photovoltaic module 2 will continue to supply power to the greenhouse equipment using its stored electrical energy. At night, the third contact plate 54 will unfold, and the photovoltaic module 2 will be pushed back to the top of the greenhouse via the limiting rod 519. When the bracket for mounting the servo motor 521 contacts the end of the slot 517, the photovoltaic module 2 will stop moving.The limiting rod 519 also enters the disc-shaped cavity 518, and the third contact plate 54 reaches its maximum extended position. At this time, the servo motor 521 controls the output shaft to rotate in the reverse direction, driving the driven rod 522 to rotate in the reverse direction. During the rotation of the driven rod 522, the turntable 525 will push the positioning rod 523 to the end of the guide cavity 524 through the arc-shaped transmission rod 526. At this time, the positioning rod 523 is blocked by the mounting connecting plate 57 and cannot extend further. The turntable 525 continues to rotate, which will drive the limiting rod 519 through the positioning rod 523. When the limiting rod 519 rotates to the point where the guide cavity 524 is flush with the inner wall of the disc-shaped cavity 518... When the slots are aligned, the obstruction of the mounting connecting plate 57 is removed, and the positioning rod 523 is pushed out of the guide cavity 524 by the arc-shaped transmission rod 526 and inserted into the slot, completing the locking of the limiting rod 519. The cooperation between the limiting rod 519 and the disc-shaped cavity 518 can prevent the photovoltaic module 2 from shifting, ultimately switching the greenhouse from the open state to the closed state. The photovoltaic module 2 continues to power the lighting equipment and other electrical equipment inside the greenhouse with the electrical energy stored from photovoltaic power generation during the day. The water vapor in the air inside the greenhouse continues to condense into water droplets on the surfaces of the first contact plate 52, the second contact plate 53, and the third contact plate 54 after cooling.

[0048] Working principle of the invention: The main body of the greenhouse 1, the surrounding panels 3, and the supporting columns 4 together form a stable and enclosed planting and breeding space. The supporting panels 7 divide the interior of the greenhouse into an upper planting area and a lower breeding area. The photovoltaic modules 2 are installed on the top of the main body of the greenhouse 1 through the installation connecting plates 57 to realize the conversion of solar energy into electrical energy. When collecting water vapor, the motor screw drive assembly 59 drives the third contact plate 54 to move along the rectangular frame 51 toward the top of the shed. When the second limit block 512 abuts against the positioning blocks 585 on both sides of the second contact plate 53, it begins to drive the second contact plate 53. Finally, the second contact plate 53 and the third contact plate 54 are fully extended. At this time, the first contact plate 52, the second contact plate 53, and the third contact plate 54 form a stepped condensation surface, which is used to efficiently capture the warm and humid air inside the shed and condense it into water droplets. During the subsequent discharge of condensed water, the motor screw drive assembly 59 drives the third contact plate 54 to move diagonally downward along the rectangular frame 51. During this process, the second contact plate 53 and the third contact plate 54 move synchronously. The relative sliding between the second contact plate 53 and the first contact plate 52 will scrape off the condensed water on the lower surface of the second contact plate 53. The scraper 510 on the side of the first limiting block 511 will simultaneously scrape off the residual water on the lower surface of the gathering plate 55. After the third contact plate 54 moves to the end of the first contact plate 52, it stops moving. At this time, the second contact plate 53 continues to move. During this process, the relative sliding between the second contact plate 53 and the third contact plate 54 will scrape off the condensed water on the lower surface of the second contact plate 53. It should also be noted that the water scraped off will be absorbed by the first water-absorbing block 581 and the second water-absorbing block 582 of the water control mechanism 58. When the third contact plate 54 moves diagonally downward, it pushes the squeezing plate 583 to slide along the guide rod 584 through the push rod 586, which will squeeze the second water-absorbing block 582 and the first water-absorbing block 581 in sequence. The squeezed water flows into the guide cavity 514 and is finally guided from the outlet of the guide cavity 514 to the collection component 56 on the side of the shed. The water receiving plate 561 is lower than the water outlet and forms an angle of 75°-85° with the plumb rod 562. When the second contact plate 53 and the third contact plate 54 are in the unfolded state, the plumb rod 562 is in a vertical state under the support of the hollow cylinder 563, the spring and the connecting block 564. At this time, the water receiving plate 561 can receive water droplets sliding down from the lower surface of the first contact plate 52. When the third contact plate 54 moves downward at an angle, the extension rod 513 at its end slides along the limiting groove 516 of the reinforcing plate 515, pushes the plumb rod 562 to rotate, and adjusts the angle of the water receiving plate 561 so that the water inside flows to the drain hole 565. The water is poured to the edge of the greenhouse through the tilted drain hole 565, and water vapor treatment is achieved without interfering with planting and breeding activities. It should also be noted that in order to ensure that the plants receive sufficient light, the photovoltaic module 2 needs to be removed. First, the servo motor 521 is started. The servo motor 521 engages with the driven rod 522 through a bevel gear. The turntable 525 at the top of the driven rod 522 pulls the arc-shaped transmission rod 526, which pulls the positioning rod 523 out of the slot and unlocks the limit rod 519. As the turntable 525 continues to rotate, it will drive the entire limiting rod 519 through the positioning rod 523. During the rotation of the limiting rod 519, the fan-shaped opening of the cavity 520 will not affect the transmission between the servo motor 521 and the driven rod 522. When the limiting rod 519 rotates to align with the strip hole 517, it begins to retract the third contact plate 54, and the photovoltaic module 2 can slide obliquely downward along the surface of the mounting connection plate 57, thereby exposing the top of the greenhouse to allow the plants to receive natural sunlight. As night falls, the third contact plate 54 unfolds, pushing the photovoltaic module 2 back to the top of the greenhouse via the limiting rod 519. When the bracket for installing the servo motor 521 contacts the end of the strip hole 517, the photovoltaic module 2 stops moving. At this time, the limiting rod 519 enters the disc-shaped cavity 518. The servo motor 521 controls the output shaft to drive the driven rod 522 in the reverse direction. The turntable 525 pushes the positioning rod 523 to the end of the guide cavity 524 and contacts the mounting connecting plate 57 via the arc-shaped transmission rod 526. As the turntable 525 continues to rotate, the positioning rod 523 drives the entire limiting rod 519. When the limiting rod 519 rotates until the guide cavity 524 aligns with the inner wall slot of the disc-shaped cavity 518, the arc-shaped transmission rod 526 pushes the positioning rod 523 into the slot, completing the locking of the limiting rod 519 and ultimately achieving the limiting of the photovoltaic module 2.
