[0027] The utility model installs an auxiliary pipe 3 to drain the exhausted hot air. Since the hot air flows upward, the hot air can enter the discharge pipe 32 through the drainage plate 33. The cross-sectional area of the discharge pipe 32 gradually decreases from bottom to top. The water molecules in the hot air are squeezed to form water droplets. The water droplets can also absorb the water molecules in the hot air during the falling process. Then the water droplets enter the drainage hopper 35 through the drainage plate 33, and then are discharged through the one-way valve 351 and the drainage pipe 352. Placing a bucket directly below the drainage pipe 352 can collect the fallen water, thereby realizing the recycling of the moisture in the hot air and saving water resources.
[0028] When ventilation is introduced into the glass greenhouse body, due to the function of the one-way valve 351 , air does not flow back into the auxiliary pipe 3 from the drain pipe 352 .
[0029] The closing assembly 2 includes an upper bracket 21, a lower bracket 22, a guide rod 23, a screw 24, a closing plate 25 and a closing motor 26. The screw 24 is provided with two sections of external threads with opposite spiral directions. The closing plate 25 is provided with two guide holes that cooperate with the guide rod 23 and threaded holes that cooperate with the screw 24. The top and bottom of the window frame 1 are provided with sliding grooves that slide with the closing plate 25. The upper bracket 21 and the lower bracket 22 are respectively arranged on the top and bottom of the window frame 1. The guide rod 23 is fixed between the upper bracket 21 and the lower bracket 22. The screw 24 is rotatably arranged on the upper bracket 21 and the lower bracket 22. The two closing plates 25 are symmetrically arranged on the guide rod 23 and the screw 24. The closing motor 26 is arranged on the top of the upper bracket 21, and the output end of the closing motor 26 is connected to the screw 24.
[0030] A sealing motor 26 is used to drive the screw rod 24 to rotate, and the two sealing plates 25 can move in opposite directions, thereby closing or opening the window frame 1. Compared with the prior art, the efficiency of opening or closing the window frame 1 is faster and the occupied space is more reasonable.
[0031] The two sealing plates 25 are provided with rubber layers on opposite sides thereof. The two rubber layers can deform when they come into contact with each other, thereby further improving the sealing performance.
[0032] The driving assembly 4 includes a driving motor 41, a first sprocket and a second sprocket 42. A suspension 37 is provided on the outer wall of the auxiliary pipe 3. A rotating shaft 331 is provided on both sides of one end of the guide plate 33. The driving motor 41 is arranged on the suspension 37. The first sprocket is arranged on the output end of the driving motor 41. The second sprocket 42 is arranged on one of the rotating shafts 331. The second sprocket 42 is connected to the first sprocket through a chain transmission.
[0033] The guide plate 33 is driven by the driving motor 41 to rotate, and the guide plate 33 can close the exhaust slot 31 or the auxiliary pipe 3 .
[0034] The exhaust pipe 32 is provided with a plurality of staggered air guide plates 321 from bottom to top, so as to extend the flow path of the hot air and increase the number of collected water droplets.
[0035] The air guide plate 321 is arranged to be inclined, so that water droplets can flow naturally into the drainage hopper 35 .
[0036] The cross section of the limiting step 36 is an isosceles trapezoid. During ventilation, air enters the auxiliary pipe 3, and the limiting step 36 with an isosceles trapezoidal cross section can guide the air without causing obstruction.
[0037] The guide plate 33 is made of metal material, and a magnetic attraction layer is provided on the outer wall of the limiting step 36. After the guide plate 33 abuts against the limiting step 36, the magnetic attraction layer assists in fixing the limiting step 36 to improve stability.
[0038] Working principle: When it is necessary to discharge the hot air, the closing motor 26 works to drive the screw 24 to rotate, and the screw 24 drives the two closing plates 25 to move in the opposite direction, and the window frame 1 gradually becomes open. Then the driving motor 41 drives the first sprocket to rotate, and the first sprocket drives the second sprocket 42 to rotate through the chain, and the second sprocket 42 drives the guide plate 33 to rotate around the axis of the rotating shaft 331, and the guide plate 33 gradually changes from a horizontal state to an inclined state. The guide plate 33 in the horizontal state can close the exhaust slot 31, and then the guide plate 33 can contact the limiting step 36, the auxiliary pipe 3 is closed, and the hot air discharged from the window frame 1 can be discharged from the exhaust slot The hot air passes through the outlet 31 and enters the discharge pipe 32. After the water molecules in the hot air enter the discharge pipe 32, they will squeeze each other and condense to form condensed water. The condensed water will drip onto the air guide plate 321. The air guide plate 321 will guide the condensed water. The condensed water can also absorb the water molecules in the hot air when it flows. Then the condensed water falls into the drainage hopper 35. Then the condensed water is discharged through the one-way valve 351 and the drainage pipe 352. A bucket can be placed just below the drainage pipe 352 to collect the condensed water. When ventilation is needed into the glass greenhouse body, only the window frame 1 needs to be opened. The guide plate 33 can keep the horizontal state to allow the outside air to enter the auxiliary pipe 3.
