[0002] In recent years, smart agriculture and precision agriculture have developed rapidly, and the development trend of smart greenhouses is also to better meet the needs of contemporary precision agriculture. Smart greenhouses are based on crop growth environment models, using sensors such as air temperature and humidity, light intensity, and carbon dioxide concentration to monitor various environmental indicators in real time, and use intelligent systems to analyze data. The system automatically regulates the equipment in the greenhouse to ensure the best environmental conditions for crop growth and achieve precise planting of crops, so as to improve product quality as required.

[0003] In addition, in the face of the current situation of a large outflow of rural labor, the policy advocates the innovation of agricultural production and management systems, the development of family farms, large planting households, and new farmer cooperatives, and supports leading enterprises to form large enterprise groups through mergers, reorganizations, acquisitions, and holdings. For planting companies with a certain scale, to continuously improve the benefits of agricultural planting, it is necessary not only to improve the yield and quality of crops, but also to improve work efficiency and reduce operating costs. After the greenhouse is intelligent, work efficiency is significantly improved, labor costs can be greatly reduced, and the investment and operation of equipment can be completely calculated from the saved labor costs. Moreover, the economic benefits of applying greenhouse intelligent control systems are long-term. The longer the use time, the lower the labor cost will be.

[0046] Example

[0047] like Figure 1-Figure 6 As shown, this embodiment provides a greenhouse film winder based on a twisted spiral wire, comprising: two fixing seats 1 for connecting with the greenhouse film, a conductive twisted spiral wire 2 and a power supply 6.

[0048] The two fixing seats 1 are long strips, which have a better fixing effect on the greenhouse film. The two ends of the conductive twisted spiral wire 2 are respectively connected to the two fixing seats 1.

After the conductive twisted spiral wire 2 is powered, there is an electric charge on the conductive twisted spiral wire 2. Since the wire is soft and light in weight, the conductive twisted spiral wire 2 will shrink and curl after conducting electricity, thereby driving the two fixing seats 1 to move closer to each other, thereby realizing the winding of the greenhouse film.

[0049] Preferably, in this embodiment, a wire is further included, and the power source 6 is electrically connected to two ends of the conductive twisted helical wire 2 through the wire, so that the power source 6 supplies power to the conductive twisted helical wire 2 .

The locking component is a lock buckle, and the clamping seat 9 is locked to the fixing seat 1 by the lock buckle, wherein the greenhouse film is located between the clamping seat 9 and the fixing seat 1, and is clamped and fixed, so that the greenhouse film can be driven to move when the fixing seat 1 moves.

The greenhouse film is located between the first rubber pad 12 and the second rubber pad 13, and the greenhouse film can be protected by the first rubber pad 12 and the second rubber pad 13 to prevent the greenhouse film from being damaged during the clamping process.

[0054] Preferably, in this embodiment, the locking component is a locking bolt 10, and a mounting screw hole 14 compatible with the locking bolt 10 is provided on the side wall of the fixing seat 1, and a through hole 11 compatible with the locking bolt 10 is provided on the clamping seat 9, and the through hole 11 penetrates the clamping seat 9 from left to right, and the threaded end of the locking bolt 10 passes through the clamping seat 9 through the through hole 11, and passes through the first rubber pad 12 and the second rubber pad 13 in turn and then rotates in the mounting screw hole 14, and the locking bolt 10 is threadedly connected with the mounting screw hole 14, and by rotating the locking bolt 10, the locking bolt 10 is rotated into the mounting screw hole 14, driving the clamping seat 9 to move closer to the fixing seat 1, so that the first rubber pad 12 and the second rubber pad 13 between the clamping seat 9 and the fixing seat 1 clamp and fix the greenhouse film.

[0055] Preferably, in this embodiment, there are two locking bolts 10, two mounting screw holes 14 on the fixing seat 1, and two through holes 11 on the clamping seat 9. Two locking bolts 10 can achieve better balance during clamping.

[0056] Preferably, in this embodiment, a magnetic component for connecting with the shed frame is further provided on the fixing seat 1. The fixing seat 1 is adsorbed on the shed frame by the magnetic component, so that one fixing seat 1 is fixed and the other fixing seat 1 can be moved, thereby making it more convenient to use and having a wider range of applications.

[0057] Preferably, in this embodiment, the magnetic component is a magnet 16, a groove 15 is provided on the fixing seat 1, the magnet 16 is fixedly connected in the groove 15 by adhesive, and a fixing seat 1 is magnetically attracted to the shed frame body by the magnet 16. Thus, the fixing seat 1 is very convenient to connect with the shed frame body, and can be conveniently moved when it needs to be moved, which is convenient to use.

[0062] Preferably, in this embodiment, the conductive yarn 8 is carbon fiber.

[0063] When this embodiment is actually used, the upper fixing seat 1 is magnetically attracted to the greenhouse frame body through the magnet 16, and the lower fixing seat 1 is connected to the greenhouse film through the cooperation of the clamping seat 9 and the fixing seat 1. At this time, the conductive twisted spiral wire 2 is set vertically. When the power supply 6 is energized to the conductive twisted spiral wire 2, the conductive yarn 8 is heated to cause the thermal expansion yarn 7 to expand in volume, thereby causing the spiral yarn to rotate and then contract, thereby driving the lower fixing seat 1 to move upward, completing the upward pulling action, rolling up the greenhouse film, and opening the window of the greenhouse. When the greenhouse film needs to be put down, the power supply of the power supply 6 is disconnected, and the lower fixing seat 1 drives the greenhouse film to be naturally put down under the action of gravity. Of course, a second device of this invention can also be set to form a downward pulling force, so that the greenhouse film can be quickly rolled up and put down, which is more effective.
