[0032] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-4The invention shows a high-efficiency energy-saving heat storage and warming device for a greenhouse, which includes a plurality of solar thermal collecting panels 2 symmetrically installed on the wall of the greenhouse 001, and a temperature sensor is installed inside the greenhouse 001. A driving motor 8 is installed on the surface of the wall of the greenhouse 001, and the output end of the driving motor 8 is connected to a No. 2 shaft 11, and a plurality of No. 1 shafts 10 corresponding to the solar thermal collecting panels 2 are arranged vertically on the surface of the No. 2 shaft 11. The surface of each No. 1 shaft 10 is respectively connected to the surface of each solar thermal collecting panel 2. The surface of the wall of the greenhouse 001 is movably connected to a rotating motor 9 through a movable arm. The top surfaces of the plurality of No. 1 shafts 10 are all sleeved with gear plates 13. The outer side of the gear plate 13 is meshed with a transmission chain 12. The output end of the rotating motor 9 is connected to the top of one of the No. 1 shafts 10.

[0035] The surface of the wall of greenhouse 001 is installed with an emergency heat source 3 located behind the solar thermal collecting panel 2, the rear wall of greenhouse 001 is arranged with a phase change energy storage box 4 electrically connected to the solar thermal collecting panel 2, the bottom wall of greenhouse 001 is buried with a buried pipe heat exchanger 6 electrically connected to the solar thermal collecting panel 2, the bottom wall of greenhouse 001 is arranged with a water distributor 5 and a water collector 7 symmetrically arranged about the buried pipe heat exchanger 6, and the water collector 7 is located in front of the water distributor 5, and a circulation pump 1 located in front of the solar thermal collecting panel 2 is installed on the inner wall of one side of greenhouse 001, and the circulation pump 1 is connected to the water distributor 5 and the water collector 7 through a pipe.

[0036] Specifically, when the present device serves the greenhouse 001, it collects heat using the solar thermal collector 2 during the day and stores the heat in the phase change energy storage box 4. If there is excess heat, it is stored in the buried heat exchanger 6. When the temperature in the greenhouse 001 drops at night, the phase change energy storage box 4 is started to transfer the heat stored inside to the solar thermal collector 2, so that the solar thermal collector 2 can release heat into the greenhouse 001 in the form of a heat sink, which is used for heating the greenhouse and achieving efficient utilization of solar energy. When the temperature increase is insufficient, the water distributor 5, the water collector 7 and the buried heat exchanger 6 are started to release the heat stored in the buried heat exchanger 6 to achieve a supplementary warming effect.

[0037] Figure 6As shown, when the solar thermal collector 2 collects heat during the day, in order to increase the contact area between the solar thermal collector 2 and the light, when the sunlight is directly shining on the top of the greenhouse 001, the drive motor 8 can be started to drive the second shaft 11 to rotate slightly (the rotation amplitude of the drive motor 8 is controlled within 15 degrees), driving the first shaft 10 and the solar thermal collector 2 connected thereto to deflect slightly, thereby increasing the contact area with the direct light and improving the heat collection efficiency of the solar thermal collector 2. Since the rotation amplitude of the second shaft 11 is small, after the deflection occurs, the upper rotating motor 9 can tilt closer to the wall of the greenhouse 001 (because the rotating motor 9 is movably connected to the wall of the greenhouse 001 through a movable arm, there is a certain amount of movement space, so it can tilt closer smoothly);

[0038] Figure 5 It is shown that when the sunlight is at an oblique side, the drive motor 8 is reset and the rotating motor 9 is started. Under the meshing transmission action of the gear plate 13 and the transmission chain 12, the No. 1 shaft 10 is driven to deflect slightly (the rotation amplitude of the rotating motor 9 is controlled within 15 degrees), so that the solar collector panel 2 is tilted slightly, and a gap is generated between the two adjacent solar collector panels 2, thereby facilitating the projection of light from the oblique side onto the surface of the solar collector panel 2, thereby improving the heat collection efficiency.

[0039] The second shaft 11 is composed of multiple spliced ​​rods, the diameter of one end of each spliced ​​rod away from the drive motor 8 is smaller than the diameter of the other end, and the end of each spliced ​​rod away from the drive motor 8 is located between two adjacent solar collector panels 2.

[0040] Specifically, since the thinner end of the splicing rod is located between two adjacent solar collector panels 2, when the rotary motor 9 rotates, the end of the solar collector panel 2 close to the emergency heat source 3 has more space when close to the splicing rod.

[0041] The first shaft 10 and the second shaft 11 are rotatably connected, and the installation position of the second shaft 11 is located near the top of the solar collector plate 2.

[0042] Specifically, the rotating connection method allows the No. 1 shaft 10 to smoothly drive the solar collector 2 to deflect after the rotating motor 9 is started. In addition, the installation position of the No. 2 shaft 11 is slightly upward, so even if the rotation amplitude of the No. 2 shaft 11 is small, the deflection degree of the bottom end of the solar collector 2 can be maintained at a large state to ensure sufficient contact with direct sunlight.

[0043] It also includes a regulation and control system, which includes a processor installed in the greenhouse 001, and the processor is connected to a control module and a monitoring module, wherein the control module is connected to the drive motor 8, the rotating motor 9, the small electric extension rod, the phase change energy storage box 4, the circulation pump 1 and the buried pipe heat exchanger 6 signals, and the monitoring module is connected to the temperature sensor signal, wherein the control module is used to control the start and close of the drive motor 8, the rotating motor 9, the small electric extension rod, the phase change energy storage box 4, the circulation pump 1 and the buried pipe heat exchanger 6.

[0044] The monitoring module also includes a plurality of light intensity sensors arranged in the greenhouse 001 for feeding back the light angle outside the greenhouse 001.

[0045] Specifically, the light intensity sensors are arranged on the four walls and the top wall of the greenhouse 001. They can judge the change of the light angle by the change of the light intensity, and then provide a reference basis for the control module to start the drive motor 8 or the rotation motor 9. At night, the temperature in the greenhouse 001 drops, and the temperature in the greenhouse 001 is detected by the temperature sensor, which serves as a reference basis for starting the phase change energy storage box 4, the buried pipe heat exchanger 6 and the circulation pump 1.

[0046] Second implementation method:

[0047] Figure 8 It is shown that a small electric extension pole is installed on the surface of the wall of the greenhouse 001, and the power end of the small electric extension pole is movably connected to the movable arm, and the movable arm is slidably connected to the wall surface of the greenhouse 001. The surface of the No. 1 shaft rod 10 is sleeved with a shaft disk, and the shaft disk is slidably connected to the surface of the spliced ​​rod body, and each solar collector panel 2 is located below the No. 2 shaft rod 11, and the horizontal distance between the drive motor 8 and the circulation pump 1 and the frontmost solar collector panel 2 is greater than the cross-sectional width value of a single solar collector panel 2.

[0048] Different from the first embodiment, if the light is projected onto one side of the greenhouse 001, the solar thermal collector 2 on one side of the first embodiment will not be able to achieve heat collection operation (because it is facing away from the light), which will limit the heat collection efficiency of the solar thermal collector 2 (such as Figure 7 shown).

[0049] Specifically, the distance between the movable arms is adjusted by the small electric extension rod, thereby indirectly adjusting the installation position of the No. 1 shaft rod 10 and the solar thermal collecting panel 2. The extension of the small electric extension rod indirectly drives the No. 1 shaft rod 10 and the solar thermal collecting panel 2 to move relative to the wall 001. Moreover, since the solar thermal collecting panel 2 is located below the No. 2 shaft rod 11, when the No. 1 shaft rod 10 drives the surface solar thermal collecting panel 2 to rotate, it will not be blocked by the No. 2 shaft rod 11. At the same time, the solar thermal collecting panel 2 can be smoothly turned over when the gap between it and the wall surface of the greenhouse 001 is limited. In this way, when the light is on one side, the solar thermal collecting panels 2 on both sides can collect heat (such as Figure 10 shown).

[0050] During this process, by controlling the distance between the driving motor 8 and the circulating pump 1 and the closest solar collector 2, the solar collector 2 will not encounter the obstruction of the driving motor 8 and the circulating pump 1 when turning over (such as Figure 9 shown).

[0051] The third implementation method:

[0052] Figure 11-12 It is shown that a circular groove is provided inside each gear plate 13, and the inner wall of the circular groove is provided with symmetrically arranged strip grooves. The inner wall of the strip groove is fixedly connected to an electromagnetic block 133, and a reset elastic strip 131 is installed on the surface of the electromagnetic block 133. The tail end of the reset elastic strip 131 is connected to a magnetic insertion strip 132. The surface of each No. 1 shaft rod 10 is provided with a fitting docking slot 101, and the docking slot 101 and the magnetic insertion strip 132 are interlocked with each other. The monitoring module also includes a plurality of infrared sensors (not shown in the figure) respectively installed on the surface of each solar collector panel 2, which are used to monitor obstacles during the flipping process of the solar collector panel 2.

[0053] There is a magnetic attraction between the electromagnetic block 133 and the magnetic insert 132 , and both the electromagnetic block 133 and the infrared sensor are connected to the control module signal.

[0054] The sum of the horizontal distance between the outer wall of the first shaft rod 10 and the circular groove and the cross-sectional length of the docking slot 101 is smaller than the length of the magnetic insert 132 .

[0055] Unlike the second embodiment, when the solar thermal collector panels 2 are turned over, if there are obstacles in the greenhouse 001 (including but not limited to mechanical equipment or plant support, etc.), it will affect the normal turning over of one or more solar thermal collector panels 2, thereby preventing the turning over of the entire solar thermal collector panels 2 on one side. To improve this phenomenon, this embodiment is adopted;

[0056] Specifically, by controlling the sensing range of the infrared sensor (this is existing technology and will not be described in detail), the situation in which the solar collector panel 2 is intercepted by an obstacle during the flipping process can be fed back to the control module. At this time, the control module controls the electromagnetic block 133 to start, driving the electromagnetic block 133 to attract and leave the inside of the docking slot 101. At this time, the gear plate 13 is disengaged from the No. 1 shaft 10, driving the gear plate 13 to operate normally, and will not affect the No. 1 shaft 10 at other positions, so that the solar collector panels 2 at other positions can be flipped over normally.

[0057] When the gear plate 13 and the No. 1 shaft 10 need to be reset to wait for the next round of flipping, the electromagnetic block 133 can be controlled to be powered off. Under the action of the reset elastic strip 131, the magnetic insertion strip 132 can be inserted into the fitting docking slot 101 (that is, the two adjacent docking slots 101 are in a compact and fitting arrangement. Even if the magnetic insertion strip 132 fails to dock into the docking slot 101 that is engaged when power is on, it can be smoothly engaged into the other docking slot 101 to restore the plug-in engagement state), so that the gear plate 13 can be restored to the connection state with the No. 1 shaft 10.

[0058] In summary, when this device provides heat storage and insulation treatment for greenhouse 001, it collects heat through the solar collector panel 2 during the day and stores the heat in the phase change energy storage box 4, and stores the excess heat in the buried pipe heat exchanger 6. When the temperature in greenhouse 001 drops at night, the heat energy in the phase change energy storage box 4 is transferred to the solar collector panel 2, which acts as a heat sink to return the heat to greenhouse 001. When the heat return is insufficient, the buried pipe heat exchanger 6 is used to supplement the return. When collecting heat during the day, the driving motor 8, the rotating motor 9, and the transmission chain 12 are used to adjust the position of the solar collector panel 2, so that the heat collection efficiency of the solar collector panel 2 can be improved, thereby realizing efficient heat collection operation of greenhouse 001.

[0059] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
