[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The arched air rib greenhouse with adjustable span is installed on both sides of the field. The specific span of the greenhouse is determined by the distance between the specific base mechanisms after installation. The gripping clamps on both sides of the same gripping clamp mechanism are opened and inserted into the ground. Due to the shape of the gripping clamps, after being inserted into the ground, the gripping clamps on both sides will extend inward toward the lower side and close to each other, thereby being more firmly connected to the ground, facilitating the connection and fixation of the base mechanism.

[0016] (2) This kind of arched air-rib greenhouse with adjustable span is connected to the bottom column by a movable connection between the grab plate and the bottom column. When the greenhouse is stored, the base mechanisms on both sides can be closed together. At this time, the air-rib mechanism will also be stored in the inner bin. Then, the grabbing mechanism is turned over so that the grabbing clamp faces upward, and the bottom column is retracted toward the inside of the bottom bin so that the grabbing mechanism is aligned with the two ends of the base mechanism. The two closed base mechanisms are clamped at the same time by the grabbing clamp, so that they can be stored and arranged, thereby reducing the space occupied when the greenhouse is stored.

[0017] (3) When the length of a single base structure is not enough for the use of the field, the arched air rib greenhouse with adjustable span can also be used by docking multiple base structures front and back. At this time, the grabbing and clamping mechanisms are flipped over and adjusted to the connection between the front and rear base structures, so that the grabbing and clamping mechanisms can be docked more conveniently, and the corresponding other grabbing and clamping mechanisms can still be inserted downward into the ground at the clamping point between the front and rear base structures, thereby improving the stability and convenience of the docking of the devices.

[0018] (4) After the base structure is fixed to the ground, the arched air rib greenhouse with adjustable span is lifted up to make the gear engage with the fine-tuning block one alone. At this time, the inner compartment can be moved left and right inside the base, so that the overall curvature and structure of the greenhouse can be fine-tuned. When it is adjusted to a suitable position, the fine-tuning block two is lowered. At this time, the fine-tuning block one and the fine-tuning block two simultaneously engage with the gear to complete the fixing and locking of the gear, which greatly improves the adjustment ability of the device and makes the device more flexible to use.

[0019] (5) This kind of arched air rib greenhouse with adjustable span, through the design of the air bag mechanism, when the fine-tuning block 2 is lifted to move the inner compartment, the air bag will be squeezed and stretched. Through the one-way air guide design of the air column, the external gas can be introduced into the inner compartment when the inner compartment moves left and right, and then the air rib is inflated, so that the installation of the device is equipped with a relatively simple inflation effect, and the manual operation is also very convenient. There is no need to electrically inflate the device, making the installation and use of the device more convenient and quick.

[0020] (6) The arched air-rib greenhouse with adjustable span is designed with a clamping mechanism. During the process of storing the greenhouse, the clamping mechanism is flipped over and the tip of the clamp is inserted into the air groove, thereby contacting a sealing ball, so that both ends of the air column are ventilated. At this time, the air-rib mechanism can be deflated quickly, thereby increasing the storage speed of the device.

[0021] (7) The arched air rib greenhouse with adjustable span has an air chamber design. The air chambers are connected to each other through docking mechanism one, and the air chambers are connected to docking mechanism two to replenish air from the inside of the air rib. Therefore, according to the specific shape of the air rib mechanism required, an air chamber at a certain place can be skipped, and the remaining air chambers can be connected through docking mechanism one. In this way, the air chambers that are not connected will shrink under the action of spring three, while the connected air chambers will be connected together by docking mechanism one to form a whole. In this way, through the different connection methods between the air chambers, after the inside of the air rib mechanism is fully inflated, the overall shape of the air rib mechanism will also change accordingly, thereby achieving an adjustment effect of different curvatures.

[0022] (8) The arched air-rib greenhouse with adjustable span can adjust the connection status of the air chamber at sunrise and sunset. When the air chamber is inflated, more air ribs will be covered, while when the air chamber is inflated, less air ribs will be covered, thereby correspondingly changing the shading and heat preservation effects of the greenhouse. This operation can be completed by simply adsorbing or removing the corresponding docking mechanism through a magnet, which is easy to operate and saves human resources.

[0045] The outer side of the air rib mechanism 5 is covered with a greenhouse outer film 8, the lower side of the greenhouse outer film 8 is correspondingly covered with the base mechanism 1, and a door is opened on the front side of the greenhouse outer film 8.

[0046] Working principle:

[0047] The first step: install the base mechanism 1 on both sides of the field. The specific span of the greenhouse is determined by the distance between the specific base mechanisms 1 after installation. Open the gripping clamps 405 on both sides of the same gripping clamp mechanism 4 and insert them into the ground. Due to the shape of the gripping clamps 405, after being inserted into the ground, the gripping clamps 405 on both sides will extend inward toward the lower side and close to each other, thereby more firmly connecting to the ground and facilitating the connection and fixation of the base mechanism 1.

[0048] Step 2: Through the movable connection between the grab plate 402 and the bottom column 303, when the greenhouse is stored, the base mechanisms 1 on both sides can be closed together. At this time, the air rib mechanism 5 will also be stored in the inner warehouse 106, and then the clamping mechanism 4 is turned over so that the clamp 405 is facing upward, and the bottom column 303 is retracted toward the inside of the bottom warehouse 301, so that the clamping mechanism 4 is aligned with the two ends of the base mechanism 1, and the two closed base mechanisms 1 are clamped at the same time by the clamp 405, so that they can be stored and arranged, reducing the space occupied when the greenhouse is stored.

[0049] Step 3: When the length of a single base mechanism 1 is not enough for use in the field, multiple base mechanisms 1 can also be docked front and back for use. At this time, the clamping mechanism 4 is flipped over and the clamping 405 is adjusted to clamp to the connection between the front and rear base mechanisms 1, so that the clamping mechanism 4 can be docked more conveniently, and the corresponding other clamping mechanism 4 can still be inserted downward into the ground at the clamping point of the front and rear base mechanisms 1, thereby improving the stability and convenience of the docking of the device.

[0050] Step 4: After the base mechanism 1 is fixed to the soil, the fine-tuning block 2 104 is lifted so that the gear 108 is engaged with the fine-tuning block 1 102 separately. At this time, the inner bin 106 can be moved left and right inside the base 101, so as to continue to fine-tune the overall curvature and structure of the greenhouse. When adjusted to the appropriate position, the fine-tuning block 2 104 is lowered. At this time, the fine-tuning block 1 102 and the fine-tuning block 2 104 simultaneously engage the gear 108 to complete the fixation and locking of the gear 108, which greatly improves the adjustment ability of the device and makes the device more flexible to use.

[0051] Step 5: Through the design of the airbag mechanism 2, when the fine-tuning block 2 104 is lifted to move the inner warehouse 106, the airbag 201 will be squeezed and stretched, and the one-way air guide design of the air column 203 can introduce external gas into the inner warehouse 106 when the inner warehouse 106 moves left and right, and then inflate the air rib 501, so that the installation of the device is equipped with a relatively simple inflation effect, and the manual operation is also very convenient. There is no need to electrically inflate the device, making the installation and use of the device more convenient and quick.

[0052] Step 6: Through the design of the gripping mechanism 4, during the process of storing the greenhouse, by flipping the gripping mechanism 4 and inserting the tip of the gripping clamp 405 into the air groove 204, it can resist the blocking ball 206, so that both ends of the air column 203 are ventilated. At this time, the air rib mechanism 5 can be deflated quickly to increase the storage speed of the device.

[0053] Step 7: Through the design of the air bin 502, the air bin 502 is connected to each other through the docking mechanism 1 6, and the docking mechanism 1 6 is connected to the docking mechanism 2 7 to replenish gas from the inside of the air rib 501, so that according to the specific required shape of the air rib mechanism 5, the air bin 502 at a certain place can be skipped, and the remaining air bins 502 can be connected through the docking mechanism 1 6. In this way, the unconnected air bins 502 will shrink under the action of the spring three 503, and the connected air bins 502 will be connected together by the docking mechanism 1 6 to form a whole. In this way, through the different connection methods between the air bins 502, after the inside of the air rib mechanism 5 is fully inflated, the overall shape of the air rib mechanism 5 will also change accordingly, thereby achieving an adjustment effect of different curvatures.

[0054] Step 8: You can also adjust the connection status of the air bin 502 at sunrise and sunset. When the air bin 502 is inflated, more air ribs 501 will be covered, and when the air bin 502 is inflated, less air ribs 501 will be covered, thereby correspondingly changing the shading and heat preservation effects of the greenhouse. This operation can be completed by simply adsorbing or removing the corresponding docking mechanism 6 through the magnet 602, which is easy to operate and saves human resources.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
