Description

Technical Field

[0001] This application relates to the field of agricultural production technology, and in particular to a flexible greenhouse unit and a flexible greenhouse. Background Technology

[0002] Greenhouses, also known as hothouses, provide a suitable growing environment and increase yields during seasons when plants are not suited for growth. They are primarily used for cultivating or raising seedlings of warm-weather-loving vegetables, flowers, and trees during colder seasons. Furthermore, greenhouse cultivation offers advantages such as safety, hygiene, increased yields, water and fertilizer conservation, and increased income.

[0003] In the process of developing the existing technology, the inventors discovered that:

[0004] Current technologies often rely on manual adjustment of the protective film's coverage area to regulate airflow, humidity, carbon dioxide concentration, and other environmental factors within the greenhouse, maintaining the conditions necessary for crop growth. However, manually adjusting the film's coverage area makes it difficult to adjust the opening and closing range in real time according to environmental changes, making crops susceptible to damage in the event of sudden weather changes.

[0005] Therefore, there is a need to provide a new flexible greenhouse unit or flexible greenhouse to solve the technical problem of delayed response of greenhouses to sudden weather changes. Utility Model Content

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] Please refer to Figures 1 to 2 To address the technical problem of delayed response of greenhouses to sudden weather changes, this application provides a flexible greenhouse unit 100, comprising:

[0076] A protective membrane assembly 1 with a coverage space;

[0077] Support assembly 2 is used to support the protective film assembly 1;

[0078] A film roll assembly that is connected to the protective film assembly 1 and the support assembly 2 respectively, and drives the protective film assembly 1 to move relative to the support assembly 2.

[0079] The support assembly 2 includes:

[0080] Foundation piles 21 fixed to the ground;

[0081] A load-bearing suspension cable assembly 22 connecting adjacent foundation piles 21 in the first direction;

[0082] The frame assembly 23 is erected on the load-bearing suspension cable assembly 22;

[0083] Support column group 24 connecting load-bearing suspension cable group 22 and frame group 23;

[0084] The roll film assembly includes:

[0085] A film-winding rod connected to the protective film assembly along the second direction;

[0086] At least one film winding motor is installed at one end of the film winding rod;

[0087] A film-winding swing arm connected to a film-winding motor and mounted on a load-bearing suspension cable assembly.

[0088] The protective film assembly 1 is used to protect crops within the covered space from abnormal environmental conditions such as wind, rain, and snow, thereby increasing crop yield. Preferably, the protective film assembly 1 can also maintain the room temperature within the covered space within a preset range. In specific application scenarios, the protective film assembly 1 includes at least a protective film. The protective film constitutes the covered space, that is, it constitutes a greenhouse space. Preferably, the horizontal projected area of ​​the covered space by the protective film assembly 1 is not less than the planting area of ​​the crops.

[0089] Furthermore, the protective film is made of a light-transmitting material. Preferably, in specific application scenarios, the protective film is a flexible film made of at least one of the following materials: polyethylene, polyvinyl chloride, polyolefin, and polyvinyl fluoride. This makes the protective film assembly 1 easy to transport and install. The light-transmitting nature also gives the protective film assembly 1 a sunlight-receiving surface. During the day, sunlight shines through the protective film into the covered space, allowing the covered space to absorb heat from solar radiation, thereby increasing the room temperature of the covered space.

[0090] After the room temperature rises in the space covered by the protective membrane component 1, the long-wave radiation heat reflected from the ground cannot be dissipated through the covered space, thereby reducing heat loss and creating a suitable growing environment for crops, thus increasing crop yield.

[0091] The support frame 2 supports the protective film assembly 1. Currently, the support frame 2 of most greenhouses is a metal frame, requiring a pre-installed concrete foundation, which occupies some of the land used for crop cultivation, resulting in low land utilization. Furthermore, the manufacturing, transportation, and installation costs of the metal frame are all relatively high.

[0092] Therefore, this application provides a support assembly 2, including a foundation pile 21 fixed to the ground;

[0093] A load-bearing suspension cable assembly 22 connecting adjacent foundation piles 21 in the first direction;

[0094] The frame assembly 23 is erected on the load-bearing suspension cable assembly 22;

[0095] Support column group 24 connecting load-bearing suspension cable group 22 and frame group 23.

[0096] The foundation piles 21 can be fixed to the ground in various ways. In the preferred embodiment provided in this application, to strengthen the support structure, the foundation piles 21 can be partially buried underground, with the exposed portion used to connect the load-bearing suspension cable assembly 22. The portion of the foundation pile 21 buried underground can be a concrete block, a metal block, or made of other materials or composite materials. The exposed portion of the foundation pile 21 mainly provides support for the protective membrane assembly 1. The thicker the exposed portion of the foundation pile 21, the stronger the support it provides for the protective membrane assembly 1.

[0097] Furthermore, the exposed portion of the foundation pile 21 defines the height of the flexible greenhouse unit 100. In a preferred embodiment provided in this application, the height of the flexible greenhouse unit 100 can be adjusted according to the growth habits of the crop.

[0098] The foundation piles 21 can be deployed on relatively small areas of land, minimizing the impact of pre-planned engineering locations on crop planting areas. Furthermore, the manufacturing, transportation, and installation costs of the foundation piles 21 and the suspension cable assembly are all relatively low.

[0099] In another specific embodiment provided in this application, the flexible greenhouse unit 100 further includes a support pile fixed to the ground and adjacent to the foundation pile 21. The support pile is partially buried underground, with its exposed portion having a height difference from the adjacent foundation pile 21. Typically, the exposed portion of the support pile is lower than the adjacent foundation pile 21, and the exposed portion of the support pile is connected to the exposed portion of the adjacent foundation pile 21 by a stay cable, forming a support section. The support section, the exposed portion of the support pile, and the exposed portion of the foundation pile 21 together form the three vertices of a triangle, thus ensuring that the weight of the protective membrane assembly 1 is primarily supported vertically by the foundation pile 21. The torque and bias force of the protective membrane assembly 1 when subjected to external force are balanced by the support section, the support pile, and the foundation pile 21. In one specific embodiment provided in this application, a support steel beam is provided at the top of the exposed portion of the foundation pile 21, and the load-bearing suspension cable group 22 and the stay cable are respectively connected to the support steel beam through anchors.

[0100] Typically, two sets of foundation piles 21 are arranged opposite each other. The span of the flexible greenhouse unit 100 is defined, and the span direction of the flexible greenhouse unit 100 is denoted as the first direction, and the length direction of the flexible greenhouse unit 100 is denoted as the second direction. In a preferred embodiment provided in this application, the interval between the two sets of opposing foundation piles 21 is 50 meters to 1000 meters. That is, the length of the flexible greenhouse unit 100 is 50 meters to 1000 meters.

[0101] Here, the two sets of opposing foundation piles 21 are considered as adjacent foundation piles 21. The exposed portion of each of the adjacent foundation piles 21 is connected to a load-bearing suspension cable group 22 for supporting the frame group 23 and for supporting the protective membrane assembly 1.

[0102] The following section details skeleton group 23.

[0103] The skeleton assembly 23 is used to directly support the protective membrane assembly 1, and can stably bear the weight of the protective membrane assembly 1, distribute the load, and ensure the stability of the covered space.

[0104] Furthermore, in one specific embodiment provided in this application, the skeleton group 23 includes at least an end gate skeleton and several supporting skeletons.

[0105] The end gate frame defines the end gate frame for the entrance and exit of the greenhouse unit. The support frame is set between the opposing end gate frames and defines the length of the greenhouse unit.

[0106] Considering that the protective membrane assembly 1 is likely to be torn or crushed by accumulated rainwater and snowmelt, in a specific embodiment provided in this application, the end gate frame or support frame is composed of arc-shaped ribs. The arc-shaped ribs give the protective membrane assembly 1 a drainage slope, and the two ends of the arc-shaped ribs are respectively connected to the gutter 32 and discharged through the drain pipe 31 that is connected to the gutter 32, so as to prevent rainwater or snowmelt from stagnating on the surface of the protective membrane assembly 1 and prevent water accumulation on the surface of the protective membrane assembly 1, thereby preventing it from being torn or crushed.

[0107] The gutter 32 is located at both ends of the frame assembly 23 and extends along the length of the greenhouse unit, collecting water from multiple drainage slopes on the same longitudinal direction. The gutter 32 is also connected to a drain pipe 31, which guides the collected water from the gutter 32 to the ground drainage system or water collection device. The drain pipes 31 can be distributed along the gutter 32 or inclined at both ends of the gutter 32 to ensure smooth flow of water to the downstream drainage system or water collection device.

[0108] Furthermore, in one specific embodiment provided in this application, the end gate frame or support frame can be formed by splicing two arc-shaped bone rods to facilitate assembly and transportation.

[0109] Specifically, the end gate frame includes:

[0110] A first bone rod with one end connected to the gutter 32;

[0111] A second bone rod, one end of which is connected to the gutter 32 and the other end of which is connected to the first bone rod;

[0112] The first and second ribs are at an angle so that the protective membrane assembly 1 covering the first and second ribs forms a drainage slope to drain accumulated water into the gutter 32;

[0113] The supporting frame includes:

[0114] A third rib rod with one end connected to the gutter 32;

[0115] A fourth bone rod, one end of which is connected to the gutter 32 and the other end of which is connected to the third bone rod;

[0116] The third and fourth ribs are at an angle so that the protective membrane assembly 1 covering the third and fourth ribs forms a drainage slope to drain accumulated water into the gutter 32.

[0117] The following describes the support column group 24.

[0118] It should be noted that the wind pressure is usually greatest at both ends of the protective membrane assembly 1, and the end gate frame needs to be reinforced with support columns 24 to enhance its resistance. Because the load on the top and sides of the protective membrane assembly 1 is evenly distributed, the support columns 24 are needed to effectively disperse stress concentration.

[0119] Therefore, the support column group 24 can have three forms depending on the actual usage requirements.

[0120] In one specific embodiment provided in this application, the support column assembly 24 is deployed on the end gate frame. Specifically, the load-bearing suspension cable assembly 22 includes at least:

[0121] The first load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0122] The support column assembly 24 includes at least:

[0123] Several end posts that connect the first backbone to the first load-bearing suspension cable, or connect the second backbone to the first load-bearing suspension cable.

[0124] In this embodiment, the first load-bearing suspension cable is connected to the end frame. The plurality of end posts are vertically connected to the first rib and the first load-bearing suspension cable, or vertically connected to the second rib and the first load-bearing suspension cable, thereby vertically transferring the load of the first rib or the second rib to the first load-bearing suspension cable, preventing the protective membrane assembly 1 from sinking or bending due to excessive force at both ends.

[0125] In another specific embodiment provided in this application, the support column assembly 24 is deployed on the end gate frame.

[0126] Specifically, the load-bearing suspension cable assembly 22 includes at least:

[0127] The second load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0128] The support column assembly 24 includes at least:

[0129] Several inclined columns that connect the first backbone to the second load-bearing suspension cable, or connect the second backbone to the second load-bearing suspension cable.

[0130] In this embodiment, the second load-bearing suspension cable connects to the supporting frame. The plurality of inclined columns obliquely connect the first skeleton to the second load-bearing suspension cable, or obliquely connect the second skeleton to the second load-bearing suspension cable, thereby obliquely transferring the load of the first or second skeleton to the second load-bearing suspension cable, preventing the protective membrane assembly 1 from being twisted or tilted due to excessive lateral pressure at both ends.

[0131] In another specific embodiment provided in this application, the load-bearing suspension cable assembly 22 includes at least:

[0132] The third load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0133] The support column assembly 24 includes at least:

[0134] Several inclined columns that connect the third backbone to the third load-bearing suspension cable, or connect the fourth backbone to the third load-bearing suspension cable.

[0135] In this embodiment, the third load-bearing suspension cable connects to the supporting frame. The plurality of inclined columns vertically or obliquely connect the third rib to the third load-bearing suspension cable, thereby transferring the load of the third rib vertically or obliquely to the second load-bearing suspension cable, ensuring the stability of the arched drainage slope in the middle of the protective membrane assembly 1 and preventing structural failure due to deformation of the third rib material. Alternatively, the plurality of inclined columns vertically or obliquely connect the fourth rib to the third load-bearing suspension cable, thereby transferring the load of the third rib vertically to the third load-bearing suspension cable, ensuring the stability of the arched drainage slope in the middle of the protective membrane assembly 1 and preventing structural failure due to deformation of the fourth rib material.

[0136] It should be noted that, in a lower-cost implementation, only a portion of the support frames are equipped with a number of inclined columns. The support frames with inclined columns are staggered with those without.

[0137] Furthermore, in order to create a suitable growing environment for crops and increase crop yield, in one specific embodiment provided in this application, the film roll assembly includes:

[0138] A film-winding rod connected to the protective film assembly along the second direction;

[0139] At least one film winding motor is installed at one end of the film winding rod;

[0140] A film-winding swing arm connected to a film-winding motor and mounted on a load-bearing suspension cable assembly.

[0141] It should be noted that, in this embodiment, the protective film can be equipped with film-winding motors at both ends as a whole, or the protective film can be split into a first protective film and a second protective film, with film-winding motors independently installed at one end of the first and second protective films. Therefore, the adjustment strategy for the coverage space of the protective film assembly 1 can be either overall synchronous adjustment or partially asynchronous adjustment. The film-winding rod typically clamps the protective film along the length of the greenhouse unit.

[0142] Furthermore, the film winding assembly is configured such that the film winding motor drives the film winding rod to reciprocate around the mounting beam, so as to adjustably change the coverage space of the protective film.

[0143] It is understandable that when the film-winding motor rotates, it drives the film-winding rod, causing the film-winding rod to roll relative to the clamped protective film, thereby driving the clamped protective film to unfold or wrap, changing the coverage space of the protective film, thus creating a suitable growth environment for the crop and increasing the crop yield.

[0144] Furthermore, the film roll assembly also includes:

[0145] A beam is installed along the second direction, connecting to the first load-bearing suspension cable and the second heavy suspension cable.

[0146] The film-rolling swing arm is movably connected to the mounting beam and rotates around the mounting beam.

[0147] It is understood that the film winding arm is used to limit the stroke of the film winding rod to prevent damage to the protective film caused by the film winding rod exceeding its travel range. In a preferred embodiment provided in this application, an angle detection module can be installed on the mounting beam to prevent tearing caused by inconsistent film winding heights on both sides.

[0148] In summary, this application provides a flexible photovoltaic greenhouse unit that, by changing the coverage space of the protective film through a film-rolling assembly, can uniformly control the coverage area of ​​the protective film and achieve synchronous control of the opening and closing ratio. Through remote control or a preset program, the protective film can automatically close in severe weather, with a response time reduced to the second level, minimizing disaster losses.

[0149] Please refer to Figure 3 To address the technical problem of delayed response of greenhouses to sudden weather changes, this application also provides a flexible greenhouse 200, comprising:

[0150] Several flexible greenhouse units, 100;

[0151] The flexible greenhouse unit 100 includes:

[0152] A protective membrane assembly 1 with a coverage space;

[0153] Support assembly 2 is used to support the protective film assembly 1;

[0154] Drainage component 3 is used to collect water accumulated on the protective membrane component 1;

[0155] The support assembly 2 includes:

[0156] Foundation piles 21 fixed to the ground;

[0157] A load-bearing suspension cable assembly 22 connecting adjacent foundation piles 21 in the first direction;

[0158] The frame assembly 23 is erected on the load-bearing suspension cable assembly 22;

[0159] Support column group 24 connecting load-bearing suspension cable group 22 and frame group 23;

[0160] The drainage component 3 includes:

[0161] Drain pipe 31 fixed to the ground;

[0162] The gutter 32, which connects to the adjacent drain pipe 31 in the second direction, is used to collect water accumulated on the protective membrane assembly 1.

[0163] The protective film assembly 1 is used to protect crops within the covered space from abnormal environmental conditions such as wind, rain, and snow, thereby increasing crop yield. The protective film assembly 1 can also maintain the room temperature within the covered space within a preset range. In specific application scenarios, the protective film assembly 1 includes at least a protective film. The protective film constitutes the covered space, that is, it constitutes the greenhouse space. Preferably, the horizontal projected area of ​​the covered space by the protective film assembly 1 is not less than the planting area of ​​the crops.

[0164] Furthermore, the protective film is made of a light-transmitting material. Preferably, in specific application scenarios, the protective film is a flexible film made of at least one of the following materials: polyethylene, polyvinyl chloride, polyolefin, and polyvinyl fluoride. This makes the protective film assembly 1 easy to transport and install. The light-transmitting nature also gives the protective film assembly 1 a sunlight-receiving surface. During the day, sunlight shines through the protective film into the covered space, allowing the covered space to absorb heat from solar radiation, thereby increasing the room temperature of the covered space.

[0165] After the room temperature rises in the space covered by the protective membrane component 1, the long-wave radiation heat reflected from the ground cannot be dissipated through the covered space, thereby reducing heat loss and creating a suitable growing environment for crops, thus increasing crop yield.

[0166] The support frame 2 supports the protective film assembly 1. Currently, the support frame 2 of most greenhouses is a metal frame, requiring a pre-installed concrete foundation, which occupies some of the land used for crop cultivation, resulting in low land utilization. Furthermore, the manufacturing, transportation, and installation costs of the metal frame are all relatively high.

[0171] The foundation piles 21 can be fixed to the ground in various ways. In the preferred embodiment provided in this application, to strengthen the support structure, the foundation piles 21 can be partially buried underground, with the exposed portion used to connect the load-bearing suspension cable assembly 22. The portion of the foundation pile 21 buried underground can be a concrete block, a metal block, or made of other materials or composite materials. The exposed portion of the foundation pile 21 mainly provides support for the protective membrane assembly 1. The thicker the exposed portion of the foundation pile 21, the stronger the support it provides for the protective membrane assembly 1.

[0172] Furthermore, the exposed portion of the foundation pile 21 defines the height of the flexible greenhouse unit 100. In a preferred embodiment provided in this application, the height of the flexible greenhouse unit 100 can be adjusted according to the growth habits of the crop.

[0173] The foundation piles 21 can be deployed on relatively small areas of land, minimizing the impact of pre-planned engineering locations on crop planting areas. Furthermore, the manufacturing, transportation, and installation costs of the foundation piles 21 and the suspension cable assembly are all relatively low.

[0174] In another specific embodiment provided in this application, the flexible greenhouse unit 100 further includes a support pile fixed to the ground and adjacent to the foundation pile 21. The support pile is partially buried underground, with its exposed portion having a height difference from the adjacent foundation pile 21. Typically, the exposed portion of the support pile is lower than the adjacent foundation pile 21, and the exposed portion of the support pile is connected to the exposed portion of the adjacent foundation pile 21 by a stay cable, forming a support section. The support section, the exposed portion of the support pile, and the exposed portion of the foundation pile 21 together form the three vertices of a triangle, thus ensuring that the weight of the protective membrane assembly 1 is primarily supported vertically by the foundation pile 21. The torque and bias force of the protective membrane assembly 1 when subjected to external force are balanced by the support section, the support pile, and the foundation pile 21. In one specific embodiment provided in this application, a support steel beam is provided at the top of the exposed portion of the foundation pile 21, and the load-bearing suspension cable group 22 and the stay cable are respectively connected to the support steel beam through anchors.

[0175] Typically, two sets of foundation piles 21 are arranged opposite each other. The span of the flexible greenhouse unit 100 is defined, and the span direction of the flexible greenhouse unit 100 is denoted as the first direction, and the length direction of the flexible greenhouse unit 100 is denoted as the second direction. In a preferred embodiment provided in this application, the interval between the two sets of opposing foundation piles 21 is 50 meters to 1000 meters. That is, the length of the flexible greenhouse unit 100 is 50 meters to 1000 meters.

[0176] Here, the two sets of opposing foundation piles 21 are considered as adjacent foundation piles 21. The exposed portion of each of the adjacent foundation piles 21 is connected to a load-bearing suspension cable group 22 for supporting the frame group 23 and for supporting the protective membrane assembly 1.

[0177] The following section details skeleton group 23.

[0178] The skeleton assembly 23 is used to directly support the protective membrane assembly 1, and can stably bear the weight of the protective membrane assembly 1, distribute the load, and ensure the stability of the covered space.

[0179] Furthermore, in one specific embodiment provided in this application, the skeleton group 23 includes at least an end gate skeleton and several supporting skeletons.

[0180] The end gate frame defines the end gate frame for the entrance and exit of the greenhouse unit. The support frame is set between the opposing end gate frames and defines the length of the greenhouse unit.

[0181] Considering that the protective membrane assembly 1 is likely to be torn or crushed by accumulated rainwater and snowmelt, in a specific embodiment provided in this application, the end gate frame or support frame is composed of arc-shaped ribs. The arc-shaped ribs give the protective membrane assembly 1 a drainage slope, and the two ends of the arc-shaped ribs are respectively connected to the gutter 32 and discharged through the drain pipe 31 that is connected to the gutter 32, so as to prevent rainwater or snowmelt from stagnating on the surface of the protective membrane assembly 1 and prevent water accumulation on the surface of the protective membrane assembly 1, thereby preventing it from being torn or crushed.

[0182] The gutter 32 is located at both ends of the frame assembly 23 and extends along the length of the greenhouse unit, collecting water from multiple drainage slopes on the same longitudinal direction. The gutter 32 is also connected to a drain pipe 31, which guides the collected water from the gutter 32 to the ground drainage system or water collection device. The drain pipes 31 can be distributed along the gutter 32 or inclined at both ends of the gutter 32 to ensure smooth flow of water to the downstream drainage system or water collection device.

[0183] Furthermore, in one specific embodiment provided in this application, the end gate frame or support frame can be formed by splicing two arc-shaped bone rods to facilitate assembly and transportation.

[0184] Specifically, the end gate frame includes:

[0185] A first bone rod with one end connected to the gutter 32;

[0186] A second bone rod, one end of which is connected to the gutter 32 and the other end of which is connected to the first bone rod;

[0187] The first and second ribs are at an angle so that the protective membrane assembly 1 covering the first and second ribs forms a drainage slope to drain accumulated water into the gutter 32;

[0188] The supporting frame includes:

[0189] A third rib rod with one end connected to the gutter 32;

[0190] A fourth bone rod, one end of which is connected to the gutter 32 and the other end of which is connected to the third bone rod;

[0191] The third and fourth ribs are at an angle so that the protective membrane assembly 1 covering the third and fourth ribs forms a drainage slope to drain accumulated water into the gutter 32.

[0192] The following describes the support column group 24.

[0193] It should be noted that the wind pressure is usually greatest at both ends of the protective membrane assembly 1, and the end gate frame needs to be reinforced with support columns 24 to enhance its resistance. Because the load on the top and sides of the protective membrane assembly 1 is evenly distributed, the support columns 24 are needed to effectively disperse stress concentration.

[0194] Therefore, the support column group 24 can have three forms depending on the actual usage requirements.

[0195] In one specific embodiment provided in this application, the support column assembly 24 is deployed on the end gate frame. Specifically, the load-bearing suspension cable assembly 22 includes at least:

[0196] The first load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0197] The support column assembly 24 includes at least:

[0198] Several end posts that connect the first backbone to the first load-bearing suspension cable, or connect the second backbone to the first load-bearing suspension cable.

[0199] In this embodiment, the first load-bearing suspension cable is connected to the end frame. The plurality of end posts are vertically connected to the first rib and the first load-bearing suspension cable, or vertically connected to the second rib and the first load-bearing suspension cable, thereby vertically transferring the load of the first rib or the second rib to the first load-bearing suspension cable, preventing the protective membrane assembly 1 from sinking or bending due to excessive force at both ends.

[0200] In another specific embodiment provided in this application, the support column assembly 24 is deployed on the end gate frame.

[0201] Specifically, the load-bearing suspension cable assembly 22 includes at least:

[0202] The second load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0203] The support column assembly 24 includes at least:

[0204] Several inclined columns that connect the first backbone to the second load-bearing suspension cable, or connect the second backbone to the second load-bearing suspension cable.

[0205] In this embodiment, the second load-bearing suspension cable connects to the supporting frame. The plurality of inclined columns obliquely connect the first skeleton to the second load-bearing suspension cable, or obliquely connect the second skeleton to the second load-bearing suspension cable, thereby obliquely transferring the load of the first or second skeleton to the second load-bearing suspension cable, preventing the protective membrane assembly 1 from being twisted or tilted due to excessive lateral pressure at both ends.

[0206] In another specific embodiment provided in this application, the load-bearing suspension cable assembly 22 includes at least:

[0207] The third load-bearing suspension cable connects the adjacent foundation piles 21 and the gutter 32 in the first direction;

[0208] The support column assembly 24 includes at least:

[0209] Several inclined columns that connect the third backbone to the third load-bearing suspension cable, or connect the fourth backbone to the third load-bearing suspension cable.

[0210] In this embodiment, the third load-bearing suspension cable connects to the supporting frame. The plurality of inclined columns vertically or obliquely connect the third rib to the third load-bearing suspension cable, thereby transferring the load of the third rib vertically or obliquely to the second load-bearing suspension cable, ensuring the stability of the arched drainage slope in the middle of the protective membrane assembly 1 and preventing structural failure due to deformation of the third rib material. Alternatively, the plurality of inclined columns vertically or obliquely connect the fourth rib to the third load-bearing suspension cable, thereby transferring the load of the third rib vertically to the third load-bearing suspension cable, ensuring the stability of the arched drainage slope in the middle of the protective membrane assembly 1 and preventing structural failure due to deformation of the fourth rib material.

[0211] It should be noted that, in a lower-cost implementation, only a portion of the support frames are equipped with a number of inclined columns. The support frames with inclined columns are staggered with those without.

[0212] Furthermore, in order to create a suitable growing environment for crops and increase crop yield, in one specific embodiment provided in this application, the film roll assembly includes:

[0213] A film-winding rod connected to the protective film assembly along the second direction;

[0214] At least one film winding motor is installed at one end of the film winding rod;

[0215] A film-winding swing arm connected to a film-winding motor and mounted on a load-bearing suspension cable assembly.

[0216] It should be noted that, in this embodiment, the protective film can be equipped with film-winding motors at both ends as a whole, or the protective film can be split into a first protective film and a second protective film, with film-winding motors independently installed at one end of the first and second protective films. Therefore, the adjustment strategy for the coverage space of the protective film assembly 1 can be either overall synchronous adjustment or partially asynchronous adjustment. The film-winding rod typically clamps the protective film along the length of the greenhouse unit.

[0217] Furthermore, the film winding assembly is configured such that the film winding motor drives the film winding rod to reciprocate around the mounting beam, so as to adjustably change the coverage space of the protective film.

[0218] It is understandable that when the film-winding motor rotates, it drives the film-winding rod, causing the film-winding rod to roll relative to the clamped protective film, thereby driving the clamped protective film to unfold or wrap, changing the coverage space of the protective film, thus creating a suitable growth environment for the crop and increasing the crop yield.

[0219] Furthermore, the film roll assembly also includes:

[0220] A beam is installed along the second direction, connecting to the first load-bearing suspension cable and the second heavy suspension cable.

[0221] The film-rolling swing arm is movably connected to the mounting beam and rotates around the mounting beam.

[0222] It is understood that the film winding arm is used to limit the stroke of the film winding rod to prevent damage to the protective film caused by the film winding rod exceeding its travel range. In a preferred embodiment provided in this application, an angle detection module can be installed on the mounting beam to prevent tearing caused by inconsistent film winding heights on both sides.

[0223] In summary, this application provides a flexible photovoltaic greenhouse that, by changing the coverage space of the protective film through a roll-up assembly, can uniformly control the coverage area of ​​the protective film and achieve synchronous control of the opening and closing ratio. Through remote control or a preset program, the protective film can automatically close in severe weather, with a response time reduced to the second level, minimizing disaster losses.
