[0031] Figures 1 to 4 An embodiment of the greenhouse auxiliary insulation equipment of the present application is schematically shown.

[0032] like Figures 1 to 4 As shown, the present application discloses an auxiliary heat preservation device for a greenhouse, which includes: a support assembly 1, the support assembly 1 includes a high support seat 11 and a low support seat 12, and a mounting shaft 13 is obliquely arranged between the high support seat 11 and the low support seat 12. A focusing assembly 2, the focusing assembly 2 is arranged on the mounting shaft 13, and the upper surface of the focusing assembly 2 is a reflective surface. A photothermal assembly 3, the photothermal assembly 3 is arranged on the mounting shaft 13, is located above the focusing assembly 2, and rotates synchronously with the focusing assembly 2 along with the mounting shaft 13. The photothermal assembly 3 includes a plurality of photothermal tubes 31, which are hollow structures and are connected to the heat preservation medium pipe 4 in the greenhouse.

[0033] Through the above-mentioned structural design, the embodiment of the present application can rotatably install the focusing component 2 and the photothermal component 3 through the inclined support component 1, so that the focusing component 2 and the photothermal component 3 form an angle with the ground and can rotate with the position of the sun, thereby improving the efficiency of the direct sunlight photothermal component 3 and the focusing efficiency of the focusing component 2, so as to make full use of the solar energy heating and heat preservation medium, increase cheap heat energy for the insulation of the greenhouse, reduce the use of electricity, and reduce the cost of planting.

[0034] like Figures 1 to 4As shown, the support assembly 1 can be directly mounted on the ground. By setting up a high and low base, the concentrating assembly 2 and the photothermal assembly 3 are arranged at an angle to the ground, thereby better facing the sun to receive sunlight, improving the direct heat-raising efficiency of the photothermal assembly 3 and the concentrated heat-raising efficiency of the concentrating assembly 2. Specifically, the high support base 11 and the low support base 12 are both provided with through holes and equipped with bearings and other structures, which can rotate and fix the mounting shaft 13, thereby achieving the tracking rotation of the concentrating assembly 2 and the photothermal assembly 3, further improving the efficiency of light energy utilization.

[0035] In some embodiments of the present application, Figures 1 to 3 As shown, the solar thermal assembly 3 includes: a solar thermal mounting frame 32 and a solar thermal pipe 31. The solar thermal mounting frame 32 is connected to the mounting shaft 13 and rotates with the mounting shaft 13. The solar thermal mounting frame 32 includes a plurality of sleeves 321, and the solar thermal pipe 31 is installed in the sleeves 321. By providing the sleeves 321, the solar thermal mounting frame 32 can quickly install the solar thermal pipe 31, improve the assembly and maintenance efficiency of this embodiment, and facilitate use. Figure 3 As shown, the solar thermal mounting frame 32 is also mounted on the mounting shaft 13 using a sleeve arrangement. It includes a main sleeve for sleeve engagement with the mounting shaft 13. In this embodiment, the main sleeve of the solar thermal mounting frame 32 is configured with three sleeves 321 through multiple radiant panels 323 to simultaneously accommodate three parallel solar thermal pipes 31, thereby ensuring solar thermal efficiency. It is understood that in other embodiments of the present application, the solar thermal mounting frame 32 may also be configured with more sleeves 321 to accommodate more solar thermal pipes 31, depending on actual needs.

[0036] In some embodiments of the present application, the sleeve 321 of the solar thermal mounting frame 32 is provided with multiple installation heights. For example, the radiation plate 323 of the solar thermal mounting frame 32 is provided with a retractable structure, which is similar to the umbrella pole to achieve multi-stage telescopic adjustment, so that the distance between the solar thermal pipe 31 and the lower focusing assembly 2 can be easily changed, so that the solar thermal pipe 31 is better positioned at the highest concentration efficiency of the focusing axis. Alternatively, a solar thermal mounting frame 32 with an integrally formed structure but comprising multiple specifications can be used, and the height adjustment of the solar thermal pipe 31 can be achieved by replacing the lengths of the radiation plates 323 of the solar thermal mounting frames 32 of different specifications. By providing the sleeve 321 of the solar thermal mounting frame 32 with multiple adjustable installation heights, it is possible to cope with the changes in the solar altitude angle in different seasons, thereby always achieving a high concentration efficiency, so that the auxiliary insulation device of the present application can also provide a higher temperature insulation medium (such as water) in the autumn and winter seasons for photovoltaic insulation of the greenhouse, thereby reducing the use of electricity and reducing production costs.

[0037] In some embodiments of the present application, Figure 3As shown, connecting ribs 322 are further provided between the sleeves 321 of the photothermal mounting frame 32 to strengthen the strength of the photothermal mounting frame 32 , improve durability and stability, and extend the service life of the embodiment of the present application after installation.

[0038] In some embodiments of the present application, Figures 1 to 4 As shown, there are two groups of light-heat mounting brackets 32, which are respectively connected to the two ends of the mounting shaft 13, so as to install the light-heat pipe 31 from both ends to ensure that the light-heat pipe 31 is firmly installed and the position is stable. Figure 1 As shown, the photothermal mounting frame 32 is located outside the focusing range of the focusing assembly 2 , so it will not block the light and will not interfere with the focusing and heating efficiency of the focusing assembly 2 on the photothermal assembly 3 .

[0039] In some embodiments of the present application, the solar heat pipe 31 is made of glass and has a light-absorbing nano-coating on its surface. For example, the coating is made of an inorganic light-absorbing nano-material (such as Au nano-material) to utilize its photothermal mechanism to achieve photothermal conversion. The above-mentioned inorganic nano-materials are commercially available and are not limited in the present embodiments.

[0040] In some embodiments of the present application, Figure 2 As shown, the focusing assembly 2 includes a focusing plate 21 and mounting brackets 22. The mounting brackets 22 are connected to the mounting shaft 13 and rotate with the mounting shaft 13, securing the focusing plate 21 to the mounting brackets 22. Two sets of mounting brackets 22 are provided, one connected to each side of the mounting shaft 13 to enhance the mounting stability of the focusing plate 21. Both the mounting brackets 22 and the focusing plate 21 are provided with threaded holes, allowing them to be fastened with bolts.

[0041] In some embodiments of the present application, Figure 1 and Figure 2 The concentrating plate 21 has a symmetrical curved structure. A reflective coating is applied to its upper surface to reflect and focus sunlight, increasing the light-receiving area and thereby increasing the amount of light energy available to the solar heat pipe 31. The solar heat pipe 31 is fixed to the concentrating axis of the concentrating plate 21, allowing both its upper and lower surfaces to receive light simultaneously, achieving higher solar thermal heating efficiency.

[0042] In some embodiments of the present application, Figure 2As shown, the high support base 11 is a liftable structure. By adjusting the height of the high support base 11, the inclination angle of the mounting shaft 13 can be changed, thereby adjusting the overall ground inclination of the concentrating assembly 2 and the solar thermal assembly 3 to adapt to the changes in the solar altitude angle in different seasons, maintaining an optimal light exposure angle, and ensuring the heating and heat preservation effect. Specifically, the high support base 11 is connected by an upper and lower sleeve, which can be extended or shortened. The inner sleeve is provided with an elastic positioning pin, and the outer sleeve is provided with a row of multiple positioning holes. The positioning pins and positioning holes cooperate with each other to adjust the height.

[0043] In some embodiments of the present application, the greenhouse auxiliary insulation equipment also includes: a light-chasing drive component. The light-chasing drive component includes: a drive motor and a controller, the output end of the drive motor is connected to the mounting shaft 13, and the controller is electrically connected to the drive motor. By driving the mounting shaft 13 to rotate by the drive motor, the focusing component 2 and the photothermal component 3 can be automatically rotated to chase the light every day, so as to always face the sun at a better angle to obtain higher photothermal efficiency. The electrical connection between the controller and the drive motor is a prior art. For example, in order to further control costs, a single-chip microcomputer is directly used to control the start of the drive motor in a timer manner, so that the mounting shaft 13 can automatically rotate according to the schedule set by the sunrise and sunset time. This method does not require the installation of a light sensor, etc., and the principle is simple and the cost is lower.

[0044] This application also discloses a greenhouse, which includes the greenhouse auxiliary insulation equipment described in the above embodiments. Figure 4 As shown, the greenhouse auxiliary insulation equipment is installed near the greenhouse body and connected to the greenhouse body via an insulation medium pipe 4. This provides a continuous supply of hot water to the greenhouse body for insulation, effectively reducing energy consumption and lowering planting costs. The insulation medium pipe 4 can be buried in the soil of the greenhouse, laid on the ground, or attached to the surface of the greenhouse film, depending on the space within the greenhouse and the crops being grown.

[0045] In summary, the greenhouse auxiliary insulation equipment of the present application includes: a support assembly, a focusing assembly and a photothermal assembly; the support assembly includes a high support seat and a low support seat, and a mounting shaft is obliquely arranged between the high support seat and the low support seat; the focusing assembly is arranged on the mounting shaft, and the upper surface of the focusing assembly is a reflective surface; the photothermal assembly is arranged on the mounting shaft, located above the focusing assembly, and rotates with the mounting shaft synchronously with the focusing assembly; the photothermal assembly includes a plurality of photothermal tubes, which are hollow structures and are connected to the heat preservation medium pipeline in the greenhouse. The present application uses an obliquely arranged support assembly to rotatably install the focusing assembly and the photothermal assembly, so that the focusing assembly and the photothermal assembly form an angle with the ground, and can rotate with the position of the sun, thereby improving the efficiency of the direct sunlight photothermal assembly and the focusing efficiency of the focusing assembly, so as to make full use of solar energy to heat the heat preservation medium, increase cheap heat energy for the heat preservation of the greenhouse, reduce the use of electricity, and reduce the cost of planting.

[0046] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible.
