The switching ring body 41 drives the switching rod 47 to rotate through the engagement of the inner driving card plate 42 and the inner card plate 44. The switching rod 47 drives the driving rod 221 to rotate through the engagement. The driving rod 221 drives the linkage rod 261 to rotate through the linkage belt. When the driving rod 221 and the linkage rod 261 rotate clockwise, the linkage rod 261 reels the right traction rope 244, and the driving rod 221 releases the left traction rope 243, thereby driving the external shaft ring 242 and the moving rod 241 to move in the sliding groove. When the moving rod 241 moves, the external rod 252 is driven to move together through the connecting plate 251. When the moving rod 241 and the external rod 252 move, the internal gear 2411 meshes with the tooth groove on one side of the inner wall of the double-sided toothed chain belt 26, thereby driving the moving rod 241 to rotate. The external gear 254 meshes with the tooth grooves on the outer wall of the double-sided toothed chain belt 26, driving the external rod 252 to rotate. The rotation of the moving rod 241 drives the mounting tube 245 and the scraper soft plate 246 to rotate together. The scraper soft plate 246 scrapes the inner wall of the closed membrane layer 21 to scrape off the condensed water on the inner wall of the closed membrane layer 21. When scraping water while rotating, the water flows into the mounting tube 245 along the scraper soft plate 246 through the water guide groove 2451, and then flows out through the water guide groove 2451 below, so as to fall into the water receiving bucket 247 for water collection. When the external rod 252 rotates, it drives the external scraper plate 253 to rotate, scrapes the outer wall of the closed membrane layer 21, and cleans off the large debris on the surface of the closed membrane layer 21. It can also be used to clean snow in winter. During the winding and releasing process of the left traction rope 243 and the right traction rope 244, they are limited by the sliding groove on the planting shed body 1.

[0063] S3: When the tarpaulin needs to be turned over, the air pump simultaneously injects air into the annular inner groove 272 of the switching drive ring seat 48 and the telescopic sleeve 271. The movable piston 49 in the switching drive ring seat 48 drives the switching rod 47 to move backward under the action of air pressure, so that the inner card plate 44 is not engaged with the inner driving card plate 42 on the inner wall of the switching ring body 41. The annular inner groove 272 drives the annular piston and the movable ring plate 273 to move forward together under the action of air pressure. The movable ring plate 273 drives the pressing ring 276 and the friction pressing pad 277 to move together through the connecting rod 275, so that the alignment gear 274 is meshed with the inner end tooth groove of the double-sided toothed chain belt 26, and the driving gear 2761 is meshed with the winding gear 233. The driving gear 2761 moves forward to drive the outer ring 45 to cover the outer side of the switching ring body 41, and the outer driving card plate 43 is engaged with the outer card The plate 46 is engaged, and the rotation of the winding motor 22 drives the pressing ring 276 to rotate, thereby driving the moving ring plate 273 and the positioning gear 274 to rotate together. When the positioning gear 274 rotates, it drives the double-sided toothed chain belt 26 to rotate, thereby driving the limiting chain plate 262 and the closed film layer 21 installed on the limiting chain plate 262 to rotate together; the closed film layer 21 is close to the winding rod 232 and is disassembled and separated from the winding rod 232; finally, the closed film layer 21 is turned over as the limiting chain plate 262 moves during the rotation process; specifically, the closed film layer 21 is away from the winding rod 232. The end will bypass the linkage rod 261 under the action of the limiting chain plate 262; at this time, the original outer surface of the closed film layer 21 will be turned over to the inner wall of the greenhouse, and the side that originally faced the inside of the greenhouse will face outward in the opposite direction, realizing the closed film layer 21; this is convenient for drying;

[0064] S4: When the closed film layer 21 needs to be rolled up, one end of the closed film layer 21 is removed from the limiting chain plate 262 and installed on the winding rod 232. The winding motor 22 rotates to drive the driving gear 2761 to rotate, and the driving gear 2761 drives the winding gear 233 to rotate, thereby driving the winding rod 232 to rotate. The closed film layer 21 moves toward the winding rod 232 along the limiting chain plate 262 at the side end of the double-sided toothed chain belt 26, and the winding rod 232 winds and rewinds the closed film layer 21.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present embodiment, ordinary technicians in this field can also make many forms without departing from the purpose of the present embodiment and the scope of protection of the claims, all of which are within the protection of the present embodiment.
