DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a greenhouse covering film with a positioning function, comprising a bottom plate 1, a mounting frame 2, an outer film 3, an inner film 4, a connecting hole 5, a limiting rod 6, a connecting pad 7, a limiting round cover 8, a supporting block 9, a supporting rod 10, a connecting pipe 11, a rotating nozzle 12, a liquid inlet pipe 13, a mounting plate 14, a connecting shaft 15, a micro motor 16, a connecting rod 17, a scraper 18, a base layer 19, a first flame retardant layer 20, a second flame retardant layer 21 and an anti-ultraviolet layer 22. When the greenhouse covering film with a positioning function is used, such as Figure 1 , Figure 3 and Figure 4 The limiting structure includes a connection hole 5, a limiting rod 6, a connection pad 7 and a limiting round cover 8. Since the middle and lower ends of the mounting frame 2, the outer membrane 3 and the inner membrane 4 are all provided with connection holes 5 at equal intervals, the limiting round cover 8 is threadedly connected to the outer surface of the inner end of the limiting rod 6, and the outer end diameter of the limiting rod 6 is equal to the outer end diameter of the connection pad 7;

[0029] Therefore, the outer film 3 is covered on the upper end of the mounting frame 2 arranged at equal intervals, the limiting rod 6 is nested and connected in the connecting holes 5 arranged at equal intervals on the outer film 3 and the mounting frame 2, the inner film 4 is covered on the lower end of the mounting frame 2 arranged at equal intervals, the connecting holes 5 arranged at equal intervals on the left and right ends of the inner film 4 are nested and connected to the limiting rod 6 at corresponding positions, and the connecting pad 7 is nested and connected inside the limiting rod 6;

[0030] The limiting circular cover 8 is rotated to be threadedly connected to the outer surface of the inner end of the limiting rod 6 at the corresponding position, so that the outer end of the "T"-shaped structure in the front view is tightly against the outer film 3, and the inner end of the connecting pad 7 is tightly against the inner film 4. The positions of the outer film 3 and the inner film 4 on the mounting frame 2 are limited by the limiting rod 6 and the limiting circular cover 8, so as to have a positioning function and prevent skewness during covering;

[0031] like Figure 1 , Figure 3 and Figure 5The spray structure includes a support block 9, a support rod 10, a connecting pipe 11 and a rotating nozzle 12. Since the rotating nozzles 12 are installed at equal intervals at the lower end of the connecting pipe 11, the liquid inlet pipe 13 is connected to the rotating nozzle 12 through the connecting pipe 11. The scraper 18 with an arc-shaped structure in the front view longitudinal section is a rotating structure at the upper end of the outer film 3 through the connecting rod 17 and the connecting shaft 15, and the width of the scraper 18 is greater than the width of the outer film 3;

[0032] Therefore, when the outer membrane 3 needs to be cleaned, clean water is allowed to enter the interior of the connecting pipe 11 through the liquid inlet pipe 13, and the clean water in the connecting pipe 11 enters the rotating spray heads 12 arranged at equal intervals. When the rotating spray heads 12 rotate, the clean water is evenly sprayed on the upper outer surface of the outer membrane 3, and the micro motor 16 drives the connecting shaft 15 to rotate on the mounting plate 14 when working;

[0033] When the connecting shaft 15 rotates, the connecting rod 17 is driven to rotate, so that the connecting rod 17 drives the arc-shaped scraper 18 to rotate at the upper end of the outer film 3, so that the scraper 18 scrapes the clean water on the outer surface of the upper end of the outer film 3 to the outer surfaces of the left and right ends of the outer film 3, so that the dust on the outer surface of the outer film 3 is removed, so as to facilitate cleaning and restore light transmittance, and prevent affecting the photosynthesis of plants in the greenhouse;

[0034] like Figure 1 and Figure 2 Since the lengths of the base layer 19, the first flame retardant layer 20, the second flame retardant layer 21 and the anti-ultraviolet layer 22 are all equal, the first flame retardant layer 20 protects the lower end of the base layer 19, the second flame retardant layer 21 protects the upper end of the base layer 19, and the anti-ultraviolet layer 22 protects the second flame retardant layer 21, so that the second flame retardant layer 21 and the anti-ultraviolet layer 22 protect the base layer 19, so that the outer film 3 is both flame retardant and anti-ultraviolet, and the inner film 4 is made of the same material as the outer film 3, so the flame retardant properties of the outer film 3 and the inner film 4 can be used to improve the service life. The electrical components contained above are all existing technologies and will not be described in detail here.
