[0002] The single-arch floor-standing solar greenhouse is the most commonly used type of greenhouse in the vast areas of North China and the Central Plains. This type of greenhouse can make good use of the unobstructed long-term sunlight in the plain area to ensure the temperature inside the greenhouse.

[0003] On the other side of the single-arch floor-standing solar greenhouse is mainly a rigid wall. Since the wall side is deliberately shaded during the construction of the greenhouse, the wall heats up slowly during the daytime sunlight, resulting in a large temperature difference between the wall side and the support side inside the greenhouse after nightfall, and additional temperature control is required. For this reason, a flexible solar greenhouse and a usage method thereof are proposed. Summary of the Invention

A main rotating bracket is installed on the side of the single-arch greenhouse. The end of the main rotating bracket is installed with a secondary rotating bracket through a rotating shaft. A support rod is installed between the rotating shafts. A first heating water bag is arranged inside the main rotating bracket, and a second heating water bag is arranged inside the secondary rotating bracket. The first heating water bag is communicated with the second heating water bag. The main rotating bracket cooperates with the secondary rotating bracket to form a foldable heat-insulating outer wall.

The main rotating bracket is connected to the single-arch greenhouse through the installation connecting pieces. A storage cavity is formed between the main rotating bracket and the single-arch greenhouse. The width of the storage cavity is the same as the sum of the widths of the first heating water bag and the second heating water bag.

[0007] Preferably, the end of the main rotating bracket is provided with a plug hole, a sliding sleeve, a plug bolt and a spring. The plug hole is opened at the upper end of the main rotating bracket. The sliding sleeve is welded to one side of the plug hole. The plug bolt is sleeved inside the sliding sleeve. The spring is sleeved outside the plug bolt. The two ends of the spring are respectively connected to the end of the plug bolt and the outer wall of the main rotating bracket. A through hole matching the plug bolt is opened at one end of the secondary rotating bracket connected to the main rotating bracket.

[0008] Preferably, the through hole is located on the left side of the rotation axis of the end portion of the auxiliary rotating bracket, and the angle between the through hole and the horizontal line is 30-45°.

[0009] Preferably, the lower end of the main rotating bracket is provided with a snap-in clearance groove that cooperates with the auxiliary rotating bracket to fold toward the inside of the installation connecting plate, the upper end of the main rotating bracket is installed with a snap-in part, and the side of the single-arch greenhouse is installed with a snap-in connection seat that cooperates with the snap-in part.

[0010] Preferably, a transverse groove is provided in the middle of the support rod, and the connecting joint between the first heating water bag and the second heating water bag is located in the transverse groove of the support rod.

[0011] Preferably, the first heating water bag is connected to the second heating water bag through two groups of one-way valves, the two groups of one-way valves are fixed in the transverse grooves of the support rod, and the two groups of one-way valves are arranged in opposite directions, forming two water exchange passages between the first heating water bag and the second heating water bag.

[0012] Preferably, the capacity of the second heating water bag is greater than that of the first heating water bag, the first heating water bag is recessed inwardly toward one side of the single-arch greenhouse, and the first heating water bag is close to the side of the single-arch greenhouse to form a storage chamber for the second heating water bag to fit into.

[0013] The second object of the present invention is to provide a method for using a flexible solar greenhouse, comprising the following steps: Step A, deployment of the device under good sunlight conditions; Step B, distributing the water that needs to be heated; Step C, recovery of the device after the end of sunshine.

[0014] Preferably, the step A comprises: Step A1, when there is good sunshine condition during the day, the main rotating bracket is pushed to make the main rotating bracket rotate based on the installation connecting piece, and during the rotation of the main rotating bracket, the clamping part at the upper end of the main rotating bracket releases the clamping connection state with the clamping connection seat; Step A2, the auxiliary rotating bracket stored in the main rotating bracket and the second heating water bag arranged in the auxiliary rotating bracket are moved out of the storage cavity along with the rotation of the main rotating bracket; Step A3, rotating the secondary rotating bracket so that the secondary rotating bracket drives the second heating water bag to open, after the second heating water bag is opened, the main rotating bracket is pushed in the opposite direction, the main rotating bracket drives the first heating water bag to reset, the reset main rotating bracket drives the first heating water bag so that the first heating water bag is re-attached to the outside of the single-arch greenhouse, and the clamping part at the upper end of the main rotating bracket is clamped with the clamping connection seat again; Step A4: Continue to push the secondary rotating bracket. The secondary rotating bracket drives the second heating water bag to cover the inclined surface outside the single-arch greenhouse, and the second heating water bag maintains an inclined setting state. The said step B includes: Step B1: Squeeze a part of the water body inside the second heating water bag. A part of the water body inside the second heating water bag enters the first heating water bag through the one-way valve after being squeezed. Step B2: The first heating water bag heats the water body inside it by receiving sunlight to raise the temperature of the water body. The second heating water bag also heats the water body inside it by receiving sunlight to raise the temperature of the water body. Step B3: After there is no light condition for the first heating water bag, squeeze the first heating water bag so that the water body inside the first heating water bag enters the second heating water bag through the one-way valve. The said step C includes: Step C1: Pull the secondary rotating bracket to make the secondary rotating bracket rotate around the end of the main rotating bracket. The through hole on the secondary rotating bracket continuously adjusts its position during rotation. When the position of the through hole on the secondary rotating bracket aligns with the opening position of the insertion hole, the spring extends by its elastic force. Under the elastic force of the spring, the insertion bolt moves horizontally along the sliding sleeve, and the horizontally moving sliding sleeve passes through the insertion hole and inserts into the through hole. Step C2: Under the insertion and locking of the sliding sleeve, the relative positions of the main rotating bracket and the secondary rotating bracket are fixed. Continue to pull the secondary rotating bracket, and the secondary rotating bracket synchronously drives the main rotating bracket to rotate together. The clamping part at the upper end of the main rotating bracket releases the clamping connection state with the clamping connection seat. After the end of the secondary rotating bracket touches the ground, by releasing the connection between the sliding sleeve and the through hole, the restriction on the rotation of the secondary rotating bracket is released again. Step C3: After the rotation restriction of the secondary rotating bracket is released, push the secondary rotating bracket to drive the second heating water bag to rotate back, and the first heating water bag fits with the second heating water bag. Step C4: Push the main rotating bracket again to drive the secondary rotating bracket, the first heating water bag and the second heating water bag to fit on the outside of the single-arch greenhouse again. The clamping part at the upper end of the main rotating bracket is clamped with the clamping connection seat again, thereby completing the locking of the state of the main rotating bracket. The water body inside the second heating water bag gradually dissipates heat to the single-arch greenhouse.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention is provided with a main rotating bracket and a secondary rotating bracket. A support rod is installed between the rotating shafts. A first heating water bag is arranged inside the main rotating bracket, and a second heating water bag is arranged inside the secondary rotating bracket. The support rod is communicated with the second heating water bag. The main rotating bracket and the secondary rotating bracket cooperate to form a foldable heat-preserving outer wall, which quickly absorbs heat during the day when unfolded and slowly releases heat at night when folded.

[0016] 2. In the present invention, the first heating water bag and the second heating water bag are communicated through two groups of one-way valves. The two groups of one-way valves are fixed in the transverse grooves of the support rod and are arranged in opposite directions. Two water body exchange passages are formed between the first heating water bag and the second heating water bag. The exchange of water bodies in the first heating water bag and the second heating water bag is realized through the one-way valves, which is convenient for fully heating the water body during the day and keeping the heated water body warm at night.

[0017] 3.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments with respect to the above and additional technical features and advantages of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them.

[0021] Embodiment:

[0022] As Figure 1 - Figure 6 shown, the present invention provides a flexible solar greenhouse, including a single-arch greenhouse 1. A main rotating bracket 2 is installed on the side of the single-arch greenhouse 1. The end of the main rotating bracket 2 is installed with a secondary rotating bracket 3 through a rotating shaft. A support rod 4 is installed between the rotating shafts. A first heating water bag 5 is arranged inside the main rotating bracket 2. A second heating water bag 6 is arranged inside the secondary rotating bracket 3. The support rod 4 is communicated with the second heating water bag 6. The main rotating bracket 2 cooperates with the secondary rotating bracket 3 to form a foldable heat-insulating outer wall.

[0023] Both sides of the bottom of the main rotating bracket 2 are installed with installation connecting pieces 21 through rotating shafts. The main rotating bracket 2 is connected to the single-arch greenhouse 1 through the installation connecting pieces 21. The installation connecting pieces 21 are welded to the single-arch greenhouse 1. The main rotating bracket 2 can rotate relative to the connecting pieces 21 through the rotating shaft. A storage cavity is formed between the main rotating bracket 2 and the single-arch greenhouse 1. The width of the storage cavity is the same as the sum of the widths of the first heating water bag 5 and the second heating water bag 6. When there are good sunlight conditions during the day, push the main rotating bracket 2 to rotate the main rotating bracket 2 based on the installation connecting pieces 21. During the rotation of the main rotating bracket 2, the secondary rotating bracket 3 stored inside the main rotating bracket 2 and the second heating water bag 6 arranged inside the secondary rotating bracket 3 are moved out of the storage cavity along with the main rotating bracket 2. Rotate the secondary rotating bracket 3 to make the secondary rotating bracket 3 drive the second heating water bag 6 to open. After the second heating water bag 6 opens, push the main rotating bracket 2 in the reverse direction. The main rotating bracket 2 can drive the first heating water bag 5 to reset. After the main rotating bracket 2 is reset, the main rotating bracket 2 drives the first heating water bag 5 to make the first heating water bag 5 fit against the outside of the single-arch greenhouse 1 again. Continue to push the secondary rotating bracket 3. The secondary rotating bracket 3 drives the second heating water bag 6 to make the second heating water bag 6 cover the inclined surface on the outside of the single-arch greenhouse 1. The second heating water bag 6 has better sunlight conditions and longer sunlight time than the first heating water bag 5. Therefore, the water body in the second heating water bag 6 heats up faster.

[0024] The end of the installation connecting piece 21 is provided with a plug hole 22, a sliding sleeve 23, a plug bolt 24 and a spring 25; The insertion hole 22 is opened at the upper end of the main rotating bracket 2. The sliding sleeve 23 is welded to one side of the insertion hole 22. The insertion bolt 24 is sleeved inside the insertion hole 22. The spring 25 is sleeved outside the insertion bolt 24. The two ends of the spring 25 are respectively connected to the end of the insertion bolt 24 and the outer wall of the main rotating bracket 2. A through hole matching the insertion bolt 24 is opened at one end of the secondary rotating bracket 3 connected to the main rotating bracket 2. During the process of pulling the secondary rotating bracket 3 to drive the second heating water bag 6 to retract, the through hole on the secondary rotating bracket 3 continuously adjusts its position during rotation. When the position of the through hole on the secondary rotating bracket 3 aligns with the opening position of the insertion hole 22, the spring 25 elongates due to elastic force. Under the elastic force of the spring 25, the insertion bolt 24 moves horizontally along the sliding sleeve 23, and the horizontally moving sliding sleeve 23 passes through the insertion hole 22 and inserts into the through hole. Under the insertion and locking of the sliding sleeve 23, the relative positions of the main rotating bracket 2 and the secondary rotating bracket 3 are fixed, restricting the rotation of the secondary rotating bracket 3 relative to the main rotating bracket 2, so that the main rotating bracket 2 and the secondary rotating bracket 3 rotate as a whole, preventing the secondary rotating bracket 3 from directly hitting down when driving the second heating water bag 6 to rotate and retract; When continuing to pull the secondary rotating bracket 3, the secondary rotating bracket 3 will synchronously drive the main rotating bracket 2 to rotate together. After the end of the secondary rotating bracket 3 touches the ground, the rotation restriction of the secondary rotating bracket 3 can be released again by disconnecting the connection between the sliding sleeve 23 and the through hole. When the rotation restriction of the secondary rotating bracket 3 is released, the secondary rotating bracket 3 can be pushed to drive the second heating water bag 6 to rotate back. The first heating water bag 5 fits with the second heating water bag 6, and the second heating water bag 6 is retracted back into the storage cavity again, preparing for the reset of the main rotating bracket 2. At this time, pushing the main rotating bracket 2 again can make the main rotating bracket 2 drive the secondary rotating bracket 3, the first heating water bag 5 and the second heating water bag 6 to fit on the outside of the single-arch greenhouse 1 again, and the water body inside the second heating water bag 6 gradually dissipates heat to the single-arch greenhouse 1.

[0025] The through hole is located on the left side of the rotation axis at the end of the secondary rotating bracket 3. The included angle between the through hole and the horizontal line is 30 - 45°. After the secondary rotating bracket 3 rotates to a negative angle, the main rotating bracket 2 and the secondary rotating bracket 3 are combined into a folded shape. When the main rotating bracket 2 rotates, the secondary rotating bracket 3 can contact the ground first with the main rotating bracket 2, playing a supporting role for the main rotating bracket 2, preventing the first heating water bag 5 inside the main rotating bracket 2 from contacting the ground, and reducing the pollution of the ground to the first heating water bag 5.

[0026] A clamping and yielding groove 26 is formed at the lower end of the main rotating bracket 2 to cooperate with the secondary rotating bracket 3 to fold inside the mounting and connecting piece 21. When the secondary rotating bracket 3 folds inside the main rotating bracket 2, the end of the secondary rotating bracket 3 can be nested in the clamping and yielding groove 26. At this time, the secondary rotating bracket 3 can be completely received in the main rotating bracket 2, so that the closed main rotating bracket 2 and secondary rotating bracket 3 can maintain a neat specification, reduce the space occupation, and ensure that the closed main rotating bracket 2 and secondary rotating bracket 3 can be closely attached to the outer side of the single-arch greenhouse 1.

[0027] A clamping part 27 is installed at the upper end of the main rotating bracket 2, and a clamping connection seat 11 matching the main rotating bracket 2 is installed on the side of the single-arch greenhouse 1. When the main rotating bracket 2 fits inside the single-arch greenhouse 1, the clamping part 27 at the upper end of the main rotating bracket 2 can be clamped inside the clamping connection seat 11, thereby forming a nested connection and locking structure to limit the fitting state of the main rotating bracket 2 and ensure the stability of the setting state of the main rotating bracket 2.

[0028] A transverse groove is formed in the middle of the support rod 4, and the connection joint of the first heating water bag 5 and the second heating water bag 6 is located in the transverse groove of the support rod 4. The support rod 4 cooperates with the main rotating bracket 2 and the secondary rotating bracket 3 to support the combined body of the connected first heating water bag 5 and second heating water bag 6 in the middle of the main rotating bracket 2 and the secondary rotating bracket 3, so as to play an auxiliary limiting role in the setting state of the first heating water bag 5 and the second heating water bag 6. The first heating water bag 5 and the second heating water bag 6 are connected by two groups of one-way valves, and the two groups of one-way valves are fixed in the transverse groove of the support rod 4. The two groups of one-way valves are arranged in the opposite direction, and two water body exchange passages are formed between the first heating water bag 5 and the second heating water bag 6. When the secondary rotating bracket 3 assists the second heating water bag 6 to be arranged on the top of the single-arch greenhouse 1 for sun exposure and temperature rise, a part of the water body in the second heating water bag 6 can be squeezed into the first heating water bag 5 through one of the one-way valves by squeezing. The first heating water bag 5 can preheat the water body in the first heating water bag 5 by receiving sunlight, and the second heating water bag 6 can fully heat the water body inside the second heating water bag 6 under better sunlight conditions. After the water body in the second heating water bag 6 is heated to a certain degree, by squeezing the first heating water bag 5, the water body inside the first heating water bag 5 can enter the second heating water bag 6 through the other one-way valve. The preheated water body in the first heating water bag 5 can reduce the heat neutralization of the higher-temperature water body in the second heating water bag 6, thereby reducing the decrease in water temperature.

[0029] Further, both the first heating water bag 5 and the second heating water bag 6 have electric heating wires inside the two bags, and temperature sensors are added. When the temperature of the bag is lower than 12 degrees, the hot water bag stops heating. When the temperature of the bag is higher than 65 degrees, the electric heating wire starts heating. The models of the temperature sensor and the electric heating wire can be selected according to the actual situation and size for the corresponding power.

[0030] Further, according to the length of the actual solar greenhouse, the corresponding number of the first heating water bag 5 and the second heating water bag 6 are selected so that the first heating water bag 5 and the second heating water bag 6 can cover the entire surface of the solar greenhouse that needs to be heated.

[0031] A photothermal conversion intelligent film (PCF film) is plated on the surface layer (the layer close to the outdoors) of the first heating water bag 5 and the second heating water bag 6. This film contains the following content:

[0032] It can ensure that the first heating water bag 5 and the second heating water bag 6 absorb more heat during the day and lose less heat at night, with a higher heat retention rate.

[0033] The capacity of the second heating water bag 6 is larger than that of the first heating water bag 5. One side of the first heating water bag 5 facing the single-arch greenhouse 1 is recessed inward, and a storage chamber for the second heating water bag 6 to fit is formed on the side of the first heating water bag 5 close to the single-arch greenhouse. When recycling, the second heating water bag 6 fits in the storage chamber. After the main rotating bracket 2 fits to the outside of the single-arch greenhouse 1, the first heating water bag 5 can play a role in wrapping and shielding the second heating water bag 6, so that the heat of the water body in the second heating water bag 6 is dissipated to the single-arch greenhouse 1 as much as possible, reducing the heat loss of the water body in the second heating water bag 6.

[0034] During use, when there is good sunlight during the day, push the main rotating bracket 2 to rotate the main rotating bracket 2 based on the installation connecting piece 21. During the rotation of the main rotating bracket 2, the clamping part 27 at the upper end of the main rotating bracket 2 releases the clamping connection state with the clamping connection seat 11. The auxiliary rotating bracket 3 stored inside the main rotating bracket 2 and the second heating water bag 6 arranged inside the auxiliary rotating bracket 3 are moved out of the storage cavity along with the rotation of the main rotating bracket 2. Rotate the auxiliary rotating bracket 3 to drive the second heating water bag 6 to open. After the second heating water bag 6 opens, push the main rotating bracket 2 in the reverse direction. The main rotating bracket 2 drives the first heating water bag 5 to reset. After resetting, the main rotating bracket 2 drives the first heating water bag 5 to make the first heating water bag 5 fit on the outside of the single-arch greenhouse 1 again. The clamping part 27 at the upper end of the main rotating bracket 2 is clamped with the clamping connection seat 11 again. Continue to push the auxiliary rotating bracket 3. The auxiliary rotating bracket 3 drives the second heating water bag 6 to make the second heating water bag 6 cover the inclined surface on the outside of the single-arch greenhouse 1, and the second heating water bag 6 maintains an inclined setting state; Squeeze a part of the water body inside the second heating water bag 6. After being squeezed, a part of the water body inside the second heating water bag 6 enters into the first heating water bag 5 through the one-way valve. The first heating water bag 5 heats the water body inside the first heating water bag 5 by receiving sunlight to raise the temperature of the water body. The second heating water bag 6 also heats the water body inside the second heating water bag 6 by receiving sunlight to raise the temperature of the water body. After there is no light condition for the first heating water bag 5, squeeze the first heating water bag 5 so that the water body inside the first heating water bag 5 enters into the second heating water bag 6 through the one-way valve; After there is no sunlight condition, such as Figure 6 shown, pull the auxiliary rotating bracket 3 to make the auxiliary rotating bracket 3 rotate around the end of the main rotating bracket 2. The through hole on the auxiliary rotating bracket 3 continuously adjusts its position during the rotation. When the position of the through hole on the auxiliary rotating bracket 3 aligns with the opening position of the insertion hole 22, the spring 25 elongates. Under the elastic force of the spring 25, the insertion bolt 24 moves horizontally along the sliding sleeve 23. The horizontally moving sliding sleeve 23 passes through the insertion hole 22 and inserts into the through hole. Under the insertion and locking of the sliding sleeve 23, the relative positions of the main rotating bracket 2 and the auxiliary rotating bracket 3 are fixed; As Figure 7 shown, continue to pull the auxiliary rotating bracket 3. The auxiliary rotating bracket 3 synchronously drives the main rotating bracket 2 to rotate together. The clamping part 27 at the upper end of the main rotating bracket 2 releases the clamped connection state with the clamping connection seat 11; As Figure 8 shown, after the end of the auxiliary rotating bracket 3 touches the ground, by releasing the connection between the sliding sleeve 23 and the through hole, the rotation limit of the auxiliary rotating bracket 3 is released again. After the rotation limit of the auxiliary rotating bracket 3 is released; As Figure 9 shown, by pushing the auxiliary rotating bracket 3, the auxiliary rotating bracket 3 drives the second heating water bag 6 to rotate back. The first heating water bag 5 fits with the second heating water bag 6. Push the main rotating bracket 2 again to make the main rotating bracket 2 drive the auxiliary rotating bracket 3, the first heating water bag 5 and the second heating water bag 6 to fit again on the outside of the single-span greenhouse 1. The clamping part 27 at the upper end of the main rotating bracket 2 is clamped with the clamping connection seat 11 again, thereby completing the locking of the state of the main rotating bracket 2. The water body inside the second heating water bag 6 gradually dissipates heat to the single-span greenhouse 1.

[0035] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention.

A method for using the flexible solar greenhouse and the method for using the flexible solar greenhouse as claimed in any one of claims 1 to 9, characterized in that: The step A comprises: Step A1, when there is good sunshine during the day, the main rotating bracket (2) is pushed so that the main rotating bracket (2) rotates based on the installation connecting piece (21), and during the rotation of the main rotating bracket (2), the clamping portion (27) at the upper end of the main rotating bracket (2) releases the clamping connection state with the clamping connection seat (11); Step A2, the auxiliary rotating bracket (3) stored in the main rotating bracket (2) and the second heating water bag (6) arranged in the auxiliary rotating bracket (3) are moved out of the storage cavity along with the rotation of the main rotating bracket (2); Step A3, rotating the auxiliary rotating bracket (3) so that the auxiliary rotating bracket (3) drives the second heating water bag (6) to open, and after the second heating water bag (6) is opened, the main rotating bracket (2) is pushed in the opposite direction, and the main rotating bracket (2) drives the first heating water bag (5) to reset, and after the reset, the main rotating bracket (2) drives the first heating water bag (5) so that the first heating water bag (5) is again attached to the outer side of the single-arch greenhouse (1), and the clamping portion (27) at the upper end of the main rotating bracket (2) is clamped with the clamping connection seat (11) again; Step A4, continue to push the auxiliary rotating bracket (3), the auxiliary rotating bracket (3) drives the second heating water bag (6) so that the second heating water bag (6) covers the inclined surface outside the single-arch greenhouse (1), and the second heating water bag (6) maintains an inclined setting state; The step B comprises: Step B1, squeezing part of the water in the second heating water bag (6), so that part of the water in the second heating water bag (6) enters the first heating water bag (5) through the one-way valve after being squeezed; Step B2, the first heating water bag (5) heats the water in the first heating water bag (5) by receiving sunlight to increase the temperature of the water, and the second heating water bag (6) also heats the water in the second heating water bag (6) by receiving sunlight to increase the temperature of the water; Step B3, after the first heating water bag (5) is no longer exposed to light, the first heating water bag (5) is squeezed to allow the water inside the first heating water bag (5) to enter the second heating water bag (6) through the one-way valve; The step C comprises: Step C1, pulling the auxiliary rotating bracket (3) so that the auxiliary rotating bracket (3) rotates around the end of the main rotating bracket (2), and the through hole on the auxiliary rotating bracket (3) continuously adjusts its position during the rotation process. When the position of the through hole on the auxiliary rotating bracket (3) is aligned with the opening position of the plug hole (22), the spring (25) is extended by elastic force. Under the elastic force of the spring (25), the plug bolt (24) moves horizontally along the sliding sleeve (23), and the sliding sleeve (23) moves horizontally through the plug hole (22) and is inserted into the through hole; Step C2, under the insertion and locking of the sliding sleeve (23), the relative positions of the main rotating bracket (2) and the auxiliary rotating bracket (3) remain fixed, and the auxiliary rotating bracket (3) is continuously pulled, so that the auxiliary rotating bracket (3) synchronously drives the main rotating bracket (2) to rotate together, and the clamping portion (27) at the upper end of the main rotating bracket (2) is released from the clamping connection state with the clamping connection seat (11). After the end of the auxiliary rotating bracket (3) contacts the ground, the connection between the sliding sleeve (23) and the through hole is released, and the restriction on the rotation of the auxiliary rotating bracket (3) is released again; Step C3, after the rotation restriction of the auxiliary rotating bracket (3) is released, the auxiliary rotating bracket (3) is pushed so that the auxiliary rotating bracket (3) drives the second heating water bag (6) to rotate, and the first heating water bag (5) and the second heating water bag (6) are fitted together; Step C4, the main rotating bracket (2) is pushed again so that the main rotating bracket (2) drives the auxiliary rotating bracket (3), the first heating water bag (5) and the second heating water bag (6) to fit again on the outside of the single-arch greenhouse (1), and the clamping portion (27) at the upper end of the main rotating bracket (2) is clamped with the clamping connection seat (11) again, thereby completing the locking of the state of the main rotating bracket (2), and the water in the second heating water bag (6) gradually radiates heat to the single-arch greenhouse (1).
