Description

Technical Field

[0001] The present invention relates to the technical field of sunshade equipment, and in particular to a dynamic control method and device for an adaptive sunshade system. Background Art

[0002] With the rapid development of modern agricultural science and technology, greenhouses are increasingly used. In summer, due to strong solar radiation and greenhouse effect, the temperature is extremely hot, and the temperature in the greenhouse is even as high as 40 degrees, which stops the growth and development of crops and causes them to die. Solving the problem of cooling in summer and ensuring the normal growth of crops has become the key to summer planting in greenhouses. In terms of summer shading and cooling measures for greenhouses, the external shading system of greenhouses is an important facility for greenhouse cooling. External shading mainly refers to covering the outside of the greenhouse with a shading net. This method directly blocks solar radiation outside the greenhouse, which can effectively reduce the temperature inside the greenhouse.

[0003] In the existing technology, the shade cloth can be adjusted by rolling and pulling, but in some places on the earth, the direct sunlight has a certain deflection angle. When the direct sunlight has a certain deflection angle, the shade cloth cannot completely block the greenhouse, causing the temperature in the greenhouse to be unbalanced and the temperature difference to be large, thus affecting the growth of plants. Summary of the invention

The sunshade cloth body 17 is slidably connected to the arc-shaped rod 13 body through the metal ring 18. The metal ring 18 is evenly installed on both sides of the sunshade cloth. When the sunshade cloth body 17 is spread out, the metal ring 18 will also spread out on the arc-shaped rod 13. The metal rings 18 on both sides are respectively sleeved on the two arc-shaped rods 13 and slidably connected thereto. When the rope 8 is pulled, the metal rings 18 will be pulled out. 18 slides on the arc rod 13, and the pull rod 30 is installed at one end of the sunshade cloth. The pull rod 30 is used to pull the sunshade cloth to move. The movement of the sunshade cloth will drive the metal rings 18 on both sides to move. The middle of the pull rod 30 is connected to a second connecting block 23, and the second connecting block 23 can rotate in the middle of the pull rod 30.

When the temperature is high, the motor is started first, and the motors in the two fixing boxes 6 must be started, one to release the rope 8, and the other to roll up the rope 8, so that the sunshade cloth can be unfolded. After the sunshade cloth is unfolded, the leg mechanism 2 is operated according to the calculation of time and geographical location, so that the cross bar 4 is deflected at a certain angle, and then the sunshade frame assembly 3 is moved in the first slide groove 19, so that it can completely shade the greenhouse. When the sunshade cloth body 17 needs to be removed, the corresponding screws can be directly removed, and the two balance blocks An arc rod 13 is fixedly installed on 14 by screws. Since a metal ring 18 is sleeved on the arc rod 13, the metal ring 18 can be installed by removing the screws, and then the sunshade cloth body 17 can be installed. Due to the existence of the limit rod 12 and the first push rod 20, the first push rod 20 pushes the limit plate to drive the entire sunshade frame assembly 3 to move, and at the same time drives the movement of the sunshade cloth body 17, so that a suitable position can be selected to block more sunlight. Before this, the sunshade cloth body 17 needs to be unfolded. The sunshade cloth body 17 can be unfolded and retracted by the contraction of the rope 8, but when it needs to be tilted, the second push rod 28 in the four fixed columns 26 can be controlled to control the lifting and lowering of the lifting rod 25, so as to achieve the control of the tilt angle of the cross bar 4.
