Technical Field

[0001] This application belongs to the field of solar greenhouse technology, specifically a device for preventing the overturning of a solar greenhouse quilt and a solar greenhouse structure. Background Technology

[0002] In existing technologies, when the insulation blanket of a solar greenhouse is rolled up, under abnormal circumstances, it may continue to roll up uncontrollably beyond the preset stop position, without a relatively stable and reliable blocking device. For example, the insulation blanket may roll up uncontrollably to the north slope of the greenhouse after passing the highest point of the arched top of the greenhouse, resulting in a decrease in the insulation performance of the greenhouse and the inability to use the insulation blanket normally.

[0014] A solar greenhouse includes one or more of the anti-tipping devices for a solar greenhouse quilt described above, and further includes: a greenhouse, the greenhouse including greenhouse arches, an insulation quilt, and a quilt-rolling rod, the insulation quilt being provided on the greenhouse arches, the insulation quilt being able to be rolled around the quilt-rolling rod at the front slope of the greenhouse, adapted to control the quilt-rolling rod to roll the insulation quilt so that a preset light-transmitting window is formed at the top of the greenhouse, and the anti-tipping device is provided at the preset installation position at the top of the greenhouse; a limiter, provided on the greenhouse near the location of the anti-tipping device, adapted for the limiter to obtain information that the insulation quilt has been rolled to the preset stop position, and to send the preset stop position information to a control unit to control the power source of the quilt-rolling rod to stop providing power for rolling the insulation quilt; the anti-tipping device is used to limit the insulation quilt from being rolled when the limiter malfunctions; or, the anti-tipping device cooperates with the limiter to form multiple anti-tipping mechanisms.

[0015] Compared with the prior art, the anti-tumble device for a greenhouse quilt and the greenhouse structure provided in this application have the following beneficial effects:

[0016] 1. This application provides an anti-tipping device for a greenhouse quilt and a greenhouse structure. When the insulation quilt is rolled up to near the preset installation position, the stop part will prevent the insulation quilt from being rolled up further at the preset stop position, so as to limit the insulation quilt from being rolled up beyond the preset stop position, especially uncontrollably rolling it onto the north slope. When the insulation quilt is uncontrollably rolled up continuously, the stop component will be subjected to a large pushing impact from the insulation quilt. If the stop component is simply and directly connected to the greenhouse structure, it is difficult to ensure the firmness of the connection. Under the action of a large pushing impact force, the stop component may loosen, shift or even fall off. Therefore, the connection part is connected to the preset installation position of the greenhouse structure by a fixing component.

[0017] 2. This application provides an anti-tipping device for a greenhouse quilt and a greenhouse structure. The device includes a stop assembly comprising a stop part and a connecting part. The stop part includes a stop member and a first horizontal member, and the connecting part includes a shaped member and a second horizontal member. The stop assembly also includes a reinforcing member. The stop member, the shaped member, and the reinforcing member together form a triangular support frame. A third horizontal member connects adjacent triangular support frames. The third horizontal member connects two adjacent triangular support frames at the junction of the stop part and the connecting part, forming a three-dimensional stable frame structure, ensuring that the anti-tipping device can be stably connected to the greenhouse frame as a whole.

[0018] 3. This application provides an anti-tipping device for a greenhouse quilt and a greenhouse structure. The fixing components include a first clamp assembly and a second clamp assembly. The shaped member and the third horizontal member are reinforcedly connected to the first greenhouse arch rod through the first clamp assembly, and the shaped member and the angle steel are reinforcedly connected to the second greenhouse arch rod through the second clamp assembly. The first clamp assembly and the second clamp assembly can respectively increase the contact area and restraint with each connecting structure, and further achieve a more stable and reliable connection effect at one or more points through locking, bolting, or snap-fitting, etc., which can ensure that it is not easy to loosen under large forces or short-term impacts.

[0019] 4. This application provides an anti-tipping device for a greenhouse quilt and a greenhouse structure. A first waterproof hole and a second waterproof hole are respectively provided on a first gasket and a second gasket, allowing a first fastener and a second fastener to pass through and be fastened. In the fastened state, a third horizontal member is pressed and sealed together with the insulation quilt by the first gasket, and an angle steel is pressed and sealed together with the insulation quilt by the second gasket. This ensures that the inside and periphery of the first waterproof hole are waterproof and sealed, and the inside and periphery of the second waterproof hole are also waterproof and sealed, effectively improving the sealing effect.

[0020] 5. This application provides an anti-tipping device for a greenhouse quilt and a greenhouse structure. By setting a protective device on the stop component, the protective device can be a protective pad or a protective coating. It mainly relies on the elastic characteristics of the protective device to stop the impact force during the anti-tipping process. The protective device can also be a structural component or mechanism to reduce impact. When the rolled-up insulation quilt just comes into contact with the stop component, due to the deformation of the insulation quilt or the possible small deformation of the stop device, the insulation quilt will continue to maintain the rolled-up state for a short time. If the stop device is in direct contact with the surface of the insulation quilt, the friction is large, and the insulation quilt can easily be torn during the short period of continued rolling. The protective device can also protect the insulation quilt by reducing friction. Attached Figure Description

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] For illustrative purposes, see as follows: Figures 1-7 As shown, some representative embodiments provide an anti-tilting device for a greenhouse quilt, including a stop assembly 110. The stop assembly 110 is installed in a greenhouse 200. The greenhouse 200 generally includes a supporting structure, such as greenhouse arches 260, columns, and frames. Insulation blankets 240 and greenhouse films are generally installed on the supporting structure. The greenhouse 200, as an important facility for modern agricultural production, is a non-heated greenhouse (excluding heated seedbeds). It mainly provides a suitable environment for the cultivation or seedling raising of warm-loving crops such as vegetables through light transmission, heat storage, and insulation. It is one of the main types of vegetable facility cultivation. Therefore, during the day, sunlight shines through the greenhouse film into the greenhouse, providing light for the crops to photosynthesize. At this time, the insulation blanket 240 is generally rolled up to ensure sufficient light and good ventilation inside the greenhouse. The main function of the greenhouse film is to maintain the airtightness of the greenhouse, preventing cold air from entering, and also preventing moisture loss to a certain extent. After sunset, the temperature inside the greenhouse gradually decreases. To maintain the greenhouse temperature, the insulation blanket 240 is lowered and placed over the outside of the greenhouse film. The insulation blanket 240 serves to insulate and retain heat, reducing heat loss from the inside of the greenhouse and thus maintaining a higher nighttime temperature, which is beneficial to crop growth.

[0039] Based on the characteristics of solar radiation direction in the geographical region, solar greenhouses in the Northern Hemisphere are generally divided into south-facing slopes (also known as front slopes) and north-facing slopes (also known as back slopes). The south-facing slope is the main light-receiving surface of the solar greenhouse. During the day, sunlight penetrates the greenhouse film on the south-facing slope to enter the greenhouse, providing light and heat for the crops. The light transmittance of the south-facing slope directly affects the light intensity and temperature inside the greenhouse, making it a key area for crop photosynthesis. The north-facing slope is the north-facing side of the solar greenhouse, usually consisting of walls or a rear roof. The north-facing slope mainly serves to insulate and block cold northerly winds, reducing heat loss from the greenhouse. The walls or rear roof of the north-facing slope usually have a certain heat storage capacity, absorbing and storing heat during the day and slowly releasing it at night to maintain a stable temperature inside the greenhouse.

[0040] In one of the representative embodiments of an anti-tipping device for a greenhouse quilt provided in this application, the greenhouse 200 is divided into a south slope (front slope 210) and a north slope (rear slope 220), and the highest point area 230 of the arch formed between the south and north slopes. The preset stop position 291 is generally closer to the south slope than the boundary between the highest point area 230 and the north slope, or, under the premise of ensuring safety, the boundary between the highest point area 230 and the north slope is near the preset stop position 291. The south slope of the greenhouse 200... The insulation blanket 240 is controllably rolled up by the blanket rod 270. Here, the south slope is only limited to a specific location in the Northern Hemisphere. As the south slope is a well-lit area, the insulation blanket 240 on the south slope of the greenhouse 200 in the Northern Hemisphere can usually be rolled up. However, if the main lighting area of ​​the greenhouse 200 is different in the Southern Hemisphere or due to different landforms, those skilled in the art can adjust the position where the controllably rolled up insulation blanket 240 is located according to the different locations of the main lighting area of ​​the greenhouse 200, and it is not limited to this.

[0041] The representative embodiment given is based on the characteristic that the south slope (front slope 210) of most areas in the Northern Hemisphere has good lighting. When lighting is required during the day, the rolling rod 270 rolls up the insulation blanket 240 on the south slope from the bottom of the south slope towards the highest position area 230. The anti-tipping device 100 is set at the preset installation position 250. Furthermore, the stop component 110 of the anti-tipping device 100 is set at the preset installation position 250. Generally, the preset installation position 250 is located at the highest position area 230 of the arched top of the greenhouse 200 and near the highest position area 230 on the north slope, to ensure that the insulation blanket 240 is effectively prevented from tipping over before being rolled up to the north slope. At the same time, the installation point of the stop component 110 and the greenhouse 200 is expanded to improve the firmness and stability of the installation between the stop component 110 and the greenhouse 200. However, it is not limited to this according to actual use needs. For example, to avoid rolling up too much insulation blanket 240, especially to prevent the rolled-up insulation blanket 240 from exceeding the highest arched area 230 of the greenhouse 200, which would cause inconvenience in unrolling the insulation blanket 240 later, the preset installation position 250 can also be located directly on the south slope. If it is desired to further expand the area on the greenhouse 200 where more insulation blanket 240 can be rolled up, allowing more sunlight to penetrate into the greenhouse 200, and to effectively control the stable, safe, and manageable rolling up and unrolling of the insulation blanket 240 after it is rolled up to the north slope, the preset installation position 250 can also be expanded and set up in various areas on the north slope as needed.

[0042] In the prior art, when the insulation blanket 240 of the solar greenhouse 200 is rolled up, under abnormal circumstances, it may continue to roll up uncontrollably beyond the preset stop 291, without a relatively stable and reliable blocking device. For example, the insulation blanket 240 may roll up uncontrollably to the north slope of the greenhouse after passing the highest position area 230 of the arched top of the greenhouse 200, resulting in a decrease in the insulation performance of the greenhouse 200 and the inability of the insulation blanket 240 to be used normally.

[0043] In typical embodiments of this application, the preset installation position 250 is located at the highest point 230 of the arched top of the greenhouse 200 and near the highest point 230 on the north slope. A preset stop position 291, designed for risk mitigation, is used. For example, if the winding mechanism lacks safety protection and control measures for the controllable winding of the insulation blanket 240 on the north slope, the blanket may become uncontrollably and abnormally wound due to gravity after being wound to the north slope. Alternatively, if the winding stroke does not extend to the north slope, the abnormal winding of the insulation blanket 240 to the north slope could damage the winding mechanism or the blanket itself, or prevent normal unwinding later. Therefore, the preset stop position 291, designed for risk mitigation, is located at the arched top of the greenhouse 200. The highest position area 230 and the south slope are both included. However, in order to provide sufficient space for the stop component 110 and ensure a firm connection between the stop component 110 and the greenhouse 200, the preset installation position 250 is generally set at the highest position area 230 of the arched top of the greenhouse 200 and near the highest position area 230 on the north slope. The stop component 110 is set at the preset installation position 250. When the insulation blanket 240 is rolled up to near the preset installation position 250, the stop component 110 can stop the insulation blanket 240 to ensure that the insulation blanket 240 is blocked on the south slope or the highest position area 230 of the greenhouse 200, thereby preventing the insulation blanket 240 from uncontrollably rolling up into the north slope. However, it should be emphasized that if the rolling up and down in the north slope position is controllable, the preset stop position 291 is not restricted to the north slope.

[0044] Furthermore, the stop assembly 110 includes a stop portion 111 and a connecting portion 112. The stop portion 111 is connected to the connecting portion 112, and the stop portion 111 is connected to the preset installation position 250 at the top of the greenhouse 200 through the connecting portion 112. The stop portion 111 is generally located at or near the preset stop position 291. When the insulation blanket 240 is wound up close to the preset installation position 250, the stop portion 111 will block the insulation blanket 240 from continuing to be wound at the preset stop position 291, thereby limiting the winding of the insulation blanket 240. If the insulation blanket 240 exceeds the preset stop 291, especially if it uncontrollably flips over onto the north slope, the stop part 111 can block the insulation blanket 240 before the preset stop 291. This can reserve a stop buffer space, reducing the possibility that the insulation blanket 240 will be rolled up beyond the preset stop 291. At the same time, the stop buffer space can reduce the stop friction or impact between the stop part 111 and the insulation blanket 240 through the deformation of the stop part 111 or other buffer materials, thereby protecting the insulation blanket 240 or related mechanisms.

[0045] When the insulation blanket 240 is uncontrollably and continuously rolled up, the stop component 110 will be subjected to a large pushing impact from the insulation blanket 240. If the stop component 110 is simply and directly connected to the greenhouse 200, it is difficult to ensure the firmness of the connection. Under the action of a large pushing impact, the stop component 110 may loosen, shift or even fall off. Therefore, the connection part 112 is connected to the preset installation position 250 of the greenhouse 200 by the fixing component 120. The connection method is strengthened, including but not limited to one or more combinations of connection methods such as bolt connection, threaded connection, and snap connection.

[0046] In some embodiments, the stop portion 111 includes a stop member 1111 and a first horizontal member 1112, and the connecting portion 112 includes a shaped member 1121 and a second horizontal member 1122. The stop member 1111 and the shaped member 1121 are connected to form an integral structural member. The stop member 1111 extends toward a direction away from the greenhouse 200, so that the stop member 1111 is located in and near the preset stop position 291. The shaped member 1121 is adapted to the top contour shape of the greenhouse 200, so that the shaped member 1121 can better abut against the top of the greenhouse 200 at the preset installation position 250. In order to strengthen the stop portion 111 and the connecting portion 112 and improve the strength, connection effect and stability, the first horizontal member 1112 is connected to the stop member 1111, and the second horizontal member 1122 is connected to the shaped member 1122. The two horizontal members 1122, and the first horizontal member 1112 can increase the contact area between the stop portion 111 and the insulation blanket 240. Therefore, in general, the first horizontal member 1112 and the second horizontal member 1122 extend in the same direction as the winding axis of the insulation blanket 240 in the wound state. It should be emphasized that the interpretation of "consistent" can mean that the first horizontal member 1112 and the second horizontal member 1122 are preferably parallel to the axis of the insulation blanket 240 in the wound state, but they can also be close to parallel but not completely parallel. In particular, the interpretation of the direction of the second horizontal member 1122 being "consistent" can be expanded to be less than 90 degrees from the axis of the insulation blanket 240 in the wound state, as long as at least one of the above requirements such as improving strength, connection effect and stability is met.

[0047] In some embodiments, the stop assembly 110 further includes a reinforcing member 113. The two ends of the reinforcing member 113 are respectively connected to the positions near the ends of the stop member 1111 and the shaped member 1121. Generally, the opposite ends of the stop member 1111 and the shaped member 1121 are connected, and the reinforcing member 113 is connected to the position near the opposite end of the stop member 1111 and the shaped member 1121. Due to the inclined shape of the north slope, the shaped member 1121, which is adapted to the north slope, is inclined. Since the stop member 1111 needs to meet the requirement of blocking the wound insulation blanket 240, the stop member 1111 is generally in a vertical or nearly vertical state. Therefore, the stop member 1111, the shaped member 1121 and the reinforcing member 113 will jointly form a triangular support frame 114, which is similar to a stable triangular structure. Therefore, the structural stability of the triangular support frame 114 is stronger. When the wound insulation blanket 240 is blocked by the stop member 1111, the stop member 1111 is less likely to deform excessively.

[0048] In some embodiments, there are at least two triangular support frames 114. A first horizontal member 1112 and a second horizontal member 1122 are connected between adjacent triangular support frames 114, which can connect multiple triangular support frames 114 to form an integral frame structure. Furthermore, a third horizontal member 115 is also connected between adjacent triangular support frames 114. The third horizontal member 115 connects two adjacent triangular support frames 114 at the junction of the stop part 111 and the connecting part 112 to form a three-dimensional stable frame structure, which ensures that the anti-tipping device 100 can be stably connected to the greenhouse frame as a whole, and has stronger resistance to pressure, deformation and impact.

[0049] In some embodiments, when the number of triangular support frames 114 of the anti-tipping device 100 is two, the first horizontal member 1112 is further parallel to the axis of the wound insulation blanket 240, so that the first horizontal member 1112 can better abut against the wound insulation blanket 240, thereby improving the anti-tipping blocking effect and avoiding the first horizontal member 1112 partially abutting against the wound insulation blanket 240, which would cause the first horizontal member 1112 to be subjected to excessive force locally, thereby causing the entire anti-tipping device 100 to lose its resistance to deformation or impact.

[0050] Furthermore, when the stop part 111 is located on the front slope 210 or the highest position area 230 of the greenhouse 200, when the rolled-up insulation blanket 240 is blocked by the stop part 111 to prevent it from tipping over, it can effectively ensure that the center of gravity of the insulation blanket 240 is located directly above the front slope 210 or the highest position area 230. Assuming that the rolled-up insulation blanket 240 is supported by its own weight and the main body of the greenhouse 200, the rolled-up insulation blanket 240 should not automatically roll up towards the rear slope 220 due to its own weight, thus ensuring that the insulation blanket 240 flips into the rear slope 220.

[0051] In some embodiments, the included angle between the forming member 1121 and the stop member 1111 is set between 137 degrees and 147 degrees, and the stop member 1111 is in an upright state, or relative to the upright state, the stop member 1111 is tilted no more than 10° toward the side of the wound insulation blanket 240. This will make the bottom end of the stop part 111 closer to the north slope (front slope 210), while the top of the stop part 111 is at or near the south slope (front slope 210). When the wound insulation blanket 240... When the insulation blanket 240 approaches the preset stop position 291, the top of the stop part 111 first blocks the wound insulation blanket 240. As the insulation blanket 240 continues to be wound for a short time, the top of the stop part 111 may deform slightly towards the north slope, achieving a buffering effect and reducing the impact during the stopping process. Furthermore, the top of the stop part 111 tilting towards the north slope can also reduce the risk of the insulation blanket 240 exceeding the preset stop position 291. It should be emphasized that when... The stop 111 is tilted, and the pressure direction of the insulation blanket 240 on the stop 111 is not perpendicular to the surface of the stop 111. This causes the pushing force of the insulation blanket 240 to exert pressure on the stop 111, and part of it to overcome the friction between the insulation blanket 240 and the stop 111. This avoids the problem of large contact pressure and friction when the insulation blanket 240 and the stop 111 come into contact, which would cause the insulation blanket 240 to be subjected to large resistance along the tangent of its rotation surface. This would result in the insulation blanket 240 being subjected to large local tension due to friction with the stop 111 in a short time, which would greatly increase the possibility of damage to the insulation blanket 240. Since the stop 1111 is tilted in some embodiments, the risk of the insulation blanket 240 being damaged by tension can be effectively reduced, and it can also play a good buffering role during the stop impact.

[0052] In some embodiments, the stop 1111 and the shaped member 1121 are integrally formed. Since the stop 1111 and the shaped member 1121 bear the greatest pressure during the entire anti-rollover stopping process, the integrally formed stop 1111 and the shaped member 1121 can reduce the risk of deformation or breakage at the connection position of the stop 1111 and the shaped member 1121.

[0053] In some embodiments, the third horizontal member 115 is an elliptical tube. The upper and lower surfaces of the third horizontal member 115 are in contact with the shaped member 1121 and the insulation blanket 240, respectively, which improves the supporting performance of the third horizontal member 115 and also ensures the strength and deformation resistance of the third horizontal member 115. Furthermore, an angle steel 117 is provided at the end of the shaped member 1121 away from the stop member 1111. The angle steel 117 can be placed between the shaped member 1121 and the insulation blanket 240. The angle steel 117 and the foundation of the third horizontal member 115 are... Similar in function, it can increase the surface contact between the anti-tipping device 100 and the insulation blanket 240 during installation, reducing local overpressure on the insulation blanket 240 caused by the installation of the anti-tipping device 100, thus protecting the insulation blanket 240. Furthermore, a portion of the insulation blanket 240 abuts against the end of the forming member 1121, reducing the possibility of the forming member 1121 shifting. When the anti-tipping device is blocked, the angle steel 117 can reverse the blocking action on the forming member 1121, improving the stopping power and impact resistance of the anti-tipping device 100. Further, to ensure the connection effect between the forming member 1121 and the greenhouse 200, the forming member 1121 and the top surface of the greenhouse 200 are fitted together, improving the connection strength between the forming member 1121 and the greenhouse 200.

[0054] In some embodiments, the inner surface of the insulation blanket 240 is provided with a first greenhouse arch 261 and a second greenhouse arch 262. The fixing assembly 120 includes a first clamp assembly 121 and a second clamp assembly 122. A shaped member 1121 and a third horizontal member 115 are reinforcedly connected to the first greenhouse arch 261 via the first clamp assembly 121. A shaped member 1121 and an angle steel 117 are reinforcedly connected to the second greenhouse arch 262 via the second clamp assembly. "Reinforced connection" is understood as: relative to the direct connection of each connection structure... In this configuration, the first clamp assembly 121 and the second clamp assembly 122 can respectively increase the contact area and constraint with each connecting structure, and further achieve a more stable and reliable connection effect at one or more points by locking, bolting or snap-fitting, etc., which can ensure that it is not easy to loosen under large force or short-term impact. Each connecting structure refers to the parts or partial structures to be connected, such as the shaped part 1121, the third horizontal part 115, the angle steel 117, the first greenhouse arch rod 261 and the second greenhouse arch rod 262, etc.

[0055] In some embodiments, the first clamp assembly 121 includes a first clamp plate 1211, a second clamp plate 1213, and a first fastener 1215. After installation, the anti-tipping device 100 and the related structural components of the greenhouse 200, arranged in a typical top-to-bottom order, are: first clamp plate 1211, shape member 1121, third horizontal member 115, insulation blanket 240, first greenhouse arch rod 261, and second clamp plate 1213. The fastener locks the above structural components. Specifically, the first clamp plate 1211 is adapted to the shape member 1121, and the first clamp plate 1213... 11 can generally wrap the upper part of the shape 1121. The two sides of the first clamp plate 1211 abut against the third horizontal member 115, so that the third horizontal member 115 and the first clamp plate 1211 can enclose and limit the shape 1121. The third horizontal member 115 abuts against the top surface of the insulation blanket 240. The first greenhouse arch 261 is set at the bottom of the insulation blanket 240. The second clamp plate 1213 is located at the bottom of the first greenhouse arch 261 and wraps most of the area of ​​the first greenhouse arch 261. The two sides of the second clamp plate 1213 are connected to the insulation blanket 240. The insulation blanket 240 abuts against the bottom surface, forming a enclosure and limiting of the first greenhouse arch 261 by the insulation blanket 240 and the second clamp plate 1213. The first clamp plate 1211 has a first connecting hole 1212, the second clamp plate 1213 has a second connecting hole 1214, the third cross member 115 has a third connecting hole 1151, and the insulation blanket 240 has a fourth connecting hole 241. The axial directions of the first connecting hole 1212, the second connecting hole 1214, the third connecting hole 1151, and the fourth connecting hole 241 in the same group are consistent. Within the same group of connecting holes, a first fastener can be used. The components 1215 are connected to form the first clamp plate 1211, the shaped component 1121, the third horizontal component 115, the insulation blanket 240, the first greenhouse arch rod 261, and the second clamp plate 1213, which are tightly connected together. Generally, a first fastener 1215 includes a bolt and two nuts. The two nuts are screwed onto the two ends of the bolt. By screwing the two nuts and moving them in opposite directions, the two nuts firmly press the first clamp component and the second clamp component, thereby firmly installing the anti-tipping device 100 on the first greenhouse arch rod 261 of the greenhouse 200.

[0056] In some embodiments, the second clamp assembly 122 includes a third clamp plate 1221, a fourth clamp plate 1223, and a second fastener 1225. After installation, the anti-tipping device 100 and the greenhouse 200, in a typical top-to-bottom arrangement, consist of the following structural components: third clamp plate 1221, shaped member 1121, angle steel 117, insulation blanket 240, second greenhouse arch rod 262, and fourth clamp plate 1223. The fastener locks the above structural components. Specifically, the third clamp plate 1221 is adapted to the shaped member 1121. 221 can generally wrap the upper part of the structure of the shape 1121. The two sides of the third clamp plate 1221 abut against the angle steel 117, so that the angle steel 117 and the third clamp plate 1221 can enclose and limit the shape 1121. The angle steel 117 abuts against the top surface of the insulation blanket 240. The second greenhouse arch rod 262 is set at the bottom of the insulation blanket 240. The fourth clamp plate 1223 is located at the bottom of the second greenhouse arch rod 262 and wraps most of the area of ​​the second greenhouse arch rod 262. The two sides of the fourth clamp plate 1223 abut against the insulation blanket 240. The bottom surfaces abut against each other, forming a enclosure and limiting of the second greenhouse arch 262 by the insulation blanket 240 and the fourth clamp plate 1223. The third clamp plate 1221 has a fifth connecting hole 1222, the fourth clamp plate 1223 has a sixth connecting hole 1224, the angle steel 117 has a seventh connecting hole 1171, and the insulation blanket 240 has an eighth connecting hole 242. The axial directions of the fifth connecting hole 1222, the sixth connecting hole 1224, the seventh connecting hole 1171, and the eighth connecting hole 242 in the same group are consistent. The second fastener can pass through the same group of connecting holes. 1225 is connected to ensure that the third clamp plate 1221, the shaped piece 1121, the angle steel 117, the insulation blanket 240, the second greenhouse arch rod 262 and the fourth clamp plate 1223 are tightly connected together. Generally, a second fastener 1225 includes a bolt and two nuts. The two nuts are screwed onto the two ends of the bolt respectively. By screwing the two nuts and moving them in opposite directions, the two nuts firmly press the first clamp piece and the second clamp piece, thereby realizing the secure installation of the anti-tipping device 100 on the second greenhouse arch rod 262 of the greenhouse 200.

[0057] In some embodiments, a first gasket 116 is provided between the third cross member 115 and the insulation blanket 240, and / or a second gasket 118 is provided between the angle steel 117 and the insulation blanket 240. With the fastening of the first fastener 1215 and the second fastener 1225, the first gasket 116 can effectively seal between the insulation blanket 240 and the third cross member 115, greatly reducing the risk of water seeping into the interior of the greenhouse 200. Similarly, the second gasket 118 can effectively seal between the insulation blanket 240 and the angle steel 117, also effectively reducing the problem of water from the outside of the greenhouse 200 seeping into the interior of the greenhouse 200.

[0058] Furthermore, by providing a first waterproof hole 1161 and a second waterproof hole 1181 on the first gasket 116 and the second gasket 118 respectively, the first fastener 1215 and the second fastener 1225 can pass through the first waterproof hole 1161 and the second waterproof hole 1181 respectively and be used for fastening, so that the first clamp plate 1211, the shaped member 1121, the third horizontal member 115, the first gasket 116, the insulation blanket 240, the first greenhouse arch rod 261 and the first... The two clamping plates 1213 are tightly connected together, and the third horizontal member 115 is sealed to the insulation blanket 240 through the first gasket 116; similarly, the third clamping plate 1221, the shaped member 1121, the angle steel 117, the second gasket 118, the insulation blanket 240, the second greenhouse arch rod 262 and the fourth clamping plate 1223 are tightly connected together in the order of vertical position, and the angle steel 117 is sealed to the insulation blanket 240 through the second gasket 118;

[0059] In some embodiments, the diameter of the first waterproof hole 1161 of the first gasket 116 is slightly smaller than the diameter of the first fastener 1215, and / or the diameter of the second waterproof hole 1181 of the second gasket 118 is slightly smaller than the diameter of the second fastener 1225, so that the first gasket 116 is sealed to the first fastener 1215 by interference fit at the first waterproof hole 1161, and the second gasket 118 is sealed to the second fastener 1225 by interference fit at the second waterproof hole 1181. In the tightened state, the third cross member 115 is pressed and sealed together with the insulation blanket 240 by the first gasket 116, and the angle steel 117 is pressed and sealed together with the insulation blanket 240 by the second gasket 118. This ensures that the inside and circumference of the first waterproof hole 1161 are waterproof and sealed, and the inside and circumference of the second waterproof hole 1181 are waterproof and sealed, effectively improving the sealing effect.

[0060] In some embodiments, the stop assembly 110 is made of a metallic material, preferably rust-resistant steel, and possesses good strength and hardness to meet the requirements for impact and compression resistance during stopping. The components of the stop assembly 110 are preferably hollow tubes, and the cross-sectional shape perpendicular to the extension direction of the hollow tube is not limited; it can be circular or a shape similar to an oblong hole, etc., primarily to meet the requirements for blocking. Hollow tubes with relatively high structural strength are preferred. Furthermore, to improve the compression and impact resistance of the stop assembly 110 and reduce the risk of damage to the insulation blanket 240 caused by compression or impact, a protective device 119 can be provided on the stop assembly 110, particularly on the side of the stop assembly 110 near the wound insulation blanket 240, to better cope with the impact on the insulation blanket 240 and to protect the insulation blanket 240.

[0061] In some embodiments, the protective device 119 can be a protective pad or a protective coating, mainly relying on the elastic characteristics of the protective device 119 to stop the impact force during tipping. Of course, the specific assembly process is not limited, and can be pasting, spraying, pressing, locking, etc., and is not limited to these. In other embodiments, the protective device 119 can also be a structural component or mechanism to reduce impact. For example, a ball can be set on the side of the stop assembly 110 near the wound insulation blanket 240. When the wound insulation blanket 240 just contacts the stop assembly 110, due to the deformation of the insulation blanket 240 or the possible small deformation of the stop device, the insulation blanket 240 will continue to maintain the wound state for a short time. If the stop device is in direct contact with the surface of the insulation blanket 240, the friction is large, and the insulation blanket 240 can easily be torn during the short period of continued winding. The ball can reduce the friction to protect the insulation blanket 240. Similarly, rollers can also convert sliding friction into rolling friction to reduce the friction on the insulation blanket 240. Other methods, such as the slider method, involve the insulation blanket 240 contacting the slider, which then slides up and down on the stop assembly 110 as the insulation blanket 240 is wound, reducing friction. Of course, the slider also requires matching structures or components, such as a sliding groove and a return spring. These can be adapted to meet specific needs in other embodiments. In other embodiments, a sensor-based method can be used. When the stop device experiences pressure from the insulation blanket 240 exceeding a preset limit, the sensor is triggered. The sensor receives pressure or other information and sends it to the control center or operator, allowing for automatic or manual control to stop the continued winding of the insulation blanket 240. Information can be sent to the operator via methods including, but not limited to, SMS and audible warnings.

[0062] A solar greenhouse 200 is provided, which is equipped with at least one anti-tipping device 100 as described in this application. The greenhouse 200 includes greenhouse arches 260, insulation blankets 240, and blanket-rolling rods 270, etc. The insulation blankets 240 are mounted on the greenhouse arches 260. On the south side of the greenhouse 200, the insulation blankets 240 are wound around the blanket-rolling rods 270. The blanket-rolling rods 270 are generally driven by a motor to rotate, so that the insulation blankets 240 are wound around the blankets 270. During winding, the blankets 240 can move from the bottom of the front slope 210 towards the top of the greenhouse 200. When unwinding, the blanket-rolling rods 270 move in the opposite direction, from the top of the front slope 210 towards the bottom of the greenhouse 200. When controlling the winding of the blanket-rolling rods 270... After the insulation blanket 240 is installed, a preset light-transmitting window 280 will be formed on the front slope 210 of the greenhouse 200. This allows ordinary sunlight to enter the interior of the greenhouse 200 through the preset light-transmitting window 280, thereby controlling the internal temperature and lighting of the greenhouse 200. When the control roll rod 270 winds the insulation blanket 240 to the preset stop position 291, the limiter 290 will generally obtain the corresponding information and ultimately control the roll rod 270 to stop winding the insulation blanket 240 through the control unit, so as to avoid the problem of over-winding and causing the insulation blanket 240 to flip into the rear slope 220. However, if the limiter 290 is not set, it will generally be blocked by the anti-tipping device 100 at the preset stop position 291.

[0063] Even with limiter 290 present, it's possible that its sensitivity might decrease or it might completely fail due to external environmental factors. In this case, the blanket-winding rod 270 would continue uncontrollably winding the insulation blanket 240, causing it to flip over into the back slope 220. Therefore, an anti-tipping device 100 is installed at the preset installation position 250. When limiter 290 malfunctions, the anti-tipping device 100 can effectively prevent the insulation blanket 240 from flipping over. Alternatively, the anti-tipping device 100 and limiter 290 can work together. 90 can block simultaneously to achieve multiple anti-tipping measures or simultaneous multiple anti-tipping functions. The anti-tipping device 100 and the limiter 290 can generally be set on the top of the greenhouse 200 and multiple devices can be set, and evenly distributed along the axis of the roll rod 270. The anti-tipping device 100 and the limiter 290 can be staggered, so that the insulation blanket 240 in the rolled state of the greenhouse 200 can be restricted from turning over into the back slope 220 at multiple points, thereby improving the anti-tipping effect of the insulation blanket 240.
