When the rotating rod 32 rotates forwards, the pulling rope 36 can be wound, so that the pulling rod 31 is driven to move upwards towards the ceiling 11, and each water curtain 2 connected to the pulling rod 31 can move upwards along the ceiling 11 to cover the ceiling 11; the pull cord 36 is released when the rotation lever 32 is rotated reversely, so that the pull rod 31 moves downward by the weight of the water curtain 2 and the water curtain 2 descends downward along the lower edge of the ceiling 11 to expose the ceiling 11. Furthermore, travel switches are arranged at the upper end and the lower end of one guide rail of the two shed tops, signals of the travel switches are connected to the controller, when the roller of the pull rod moves to trigger the travel switches, the travel switches can receive the signals and transmit the signals to the controller, and the controller controls the corresponding traction motors to stop.
As shown in fig. 2 and 4, the pull rod 31 is provided with a plurality of connecting holes 35, hooks 25 are fixed on both sides of the water curtain 2, the hooks 25 are correspondingly hooked in the connecting holes 35, and the water curtain 2 and the pull rod 31 can be separated by hooking the hooks 25 into the connecting holes 35 and separating the hooks 25 from the connecting holes 35. When a certain area in the vegetable greenhouse corresponding to the roof 11 needs illumination, the water curtain 2 in the area can be detached from the pull rod 31 to promote photosynthesis in the area. In addition, the guide rod 12 is connected to the lower end edge of the ceiling 11 to be rotatable, so that the frictional resistance of the water curtain 2 moving downward or upward can be reduced by the structure of the guide rod 12, the water curtain 2 can be moved more smoothly, and the water curtain 2 can be prevented from being damaged due to the frictional resistance when being moved for a long time.
As shown in fig. 10, light intensity sensors are disposed outside the sun visors 31 on both sides of the top of the fixing frame 3, and the two light intensity sensors are respectively connected to the controller through signals. When the illumination sensor of 3 one sides of mount senses illumination intensity and reaches the certain degree, with information transmission to controller, the traction motor 33 operation of 3 opposite sides of control mount behind the controller received information makes bull stick 32 rotates, realizes pulling up or transferring of cascade 2 to make the vegetables of planting in the vegetable greenhouse receive suitable illumination, avoid insolateing or illumination intensity to hang down and influence the normal growth of vegetables, concrete description through following embodiment:
when the sunlight intensity is not strong at the moment from 6 to 9 points, the controller can control the water curtains 2 on the two sides of the shed frame 1 to descend to expose the shed roof so as to promote the photosynthesis of vegetables in the vegetable greenhouse, and simultaneously can control the refrigerating device 45 and the water pump 46 to stop working;
9 o ' clock to 11 o ' clock, sunshine illumination intensity is stronger this moment under the normal condition, probably influence the normal growth of partial vegetables, consequently accessible controller control traction motor 33 drives the bull stick 32 and rotates and will upwards pull up towards each cascade 2 on east's shed roof 11, control refrigerating plant 45 and water pump 46 work simultaneously, make cascade 2 cover the low temperature interlayer that forms the sunshade with shed roof 11, and the shed roof 11 towards west does not receive the strong light irradiation this moment, consequently each cascade 2 of this shed roof is not upwards pulled up, this mode can avoid morning vegetables to receive the insolate, and can effectually promote the photosynthesis of vegetables equally through the shed roof 11 of west.
When the temperature is from 11 o 'clock to 13 o' clock, the time is positive at the time of the midday, if the sunlight intensity is at the strongest stage in one day under the condition of high temperature, the controller can control the traction motor 33 to drive the rotating rod 32 to rotate so as to pull up each water curtain 2 on the shed tops 11 at the two sides of the shed frame 1, and simultaneously control the refrigerating device 45 and the water pump 46 to work, so that the water curtains 2 cover the shed tops 11 to form a sun-shading low-temperature interlayer, and the vegetables planted in the vegetable greenhouse are prevented from being exposed to high temperature;
when the sunlight intensity is higher at the moment from 13 o 'clock to 15 o' clock under normal conditions, the controller can control the traction motor 33 to drive the rotating rod 32 to rotate to pull up each water curtain 2 on the greenhouse top 11 facing west, and simultaneously control the refrigerating device 45 and the water pump 46 to work, so that the water curtains 2 cover the greenhouse top to form a sunshade low-temperature interlayer, and the greenhouse top 11 facing east is not irradiated by strong light, so that each water curtain of the greenhouse top 11 is lowered, so that part of the sunlight can be irradiated into the vegetable greenhouse from the greenhouse top 11 facing east, the vegetable can be prevented from being exposed to the sun in the afternoon, and the photosynthesis of the vegetable can be effectively promoted through the greenhouse top 11 facing east;
when the sunlight intensity is not strong at the moment from 15 to 6 days, the controller can control the water curtains 2 on the two sides of the shed frame 1 to fall to expose the shed roof 11 so as to promote the photosynthesis of the vegetables in the vegetable greenhouse, and can control the refrigerating device 45 and the water pump 46 to stop working.
In the above embodiment, the sunlight irradiation intensity is sensed by the illumination intensity sensor facing the east side, so that the water curtain 2 on the east side ceiling 11 is controlled to cover the ceiling 11, and the water curtain 2 on the west side ceiling 11 is controlled to be lowered below the ceiling 11; the same illumination intensity sensor through towards west responds to the sunshine intensity to control cascade 2 on west shed roof 11 and cover in shed roof 11, and control cascade 2 on east shed roof 11 and transfer to under the shed roof. Make the vegetables of planting in the vegetable greenhouse receive suitable illumination according to two kinds of modes to the photosynthesis that promotes vegetables makes the vegetables of planting in the vegetable greenhouse receive suitable illumination, with the photosynthesis that promotes vegetables, avoids insolate or illumination intensity to hang down and influence the normal growth of vegetables simultaneously.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
