[0014] The present invention provides a smart agricultural greenhouse based on the Internet of Things, which has the following beneficial effects:

[0015] (1) The invention detects the real-time temperature in the greenhouse through a temperature sensor. When the temperature is too low, the temperature sensor will start the heater to heat the greenhouse. In cold seasons, the greenhouse can maintain a relatively warm temperature, extending the growing season of crops. At the same time, the reciprocating motion of the snow removal rod will push down the snow accumulated on the top of the film to prevent the weight of the snow from being added to the greenhouse structure, which may exceed the design load. The snow removal rod contacts the protrusion, which squeezes the snow removal rod downward. The downward movement of the snow removal rod will cause the free end of the elastic telescopic rod to contract. When the snow removal rod is separated from the protrusion, the elastic telescopic rod will drive the snow removal rod to reset. The snow removal rod contacts the film by reciprocating up and down, preventing the film from being damaged due to continuous adhesion, thereby affecting the thermal insulation effect.

[0016] (2) This invention drives the bevel gear to rotate by rotating the transmission wheel, which in turn drives the slave gear to rotate, which in turn drives the fan to rotate. The moisture inside the greenhouse is discharged from the greenhouse by the rotation of the fan. The melting of snow will increase the humidity in the greenhouse and affect the normal growth of plants. At the same time, by rotating the dehumidification plate, the contact area between the humid air and the surface of the dehumidification plate can be increased, thereby improving the working efficiency of the dehumidification plate. By moving the dehumidification plate away from the telescopic elastic rod to generate shaking, the surface of the dehumidification plate is prevented from freezing, which results in the dehumidification plate being unable to effectively absorb moisture in the greenhouse and reducing the dehumidification efficiency.

[0017] (3) The invention changes the heating range of the heater by rotating the rotating plate downward, and helps achieve a more uniform heating distribution by swinging the rotating plate, thereby preventing heat accumulation that affects the heating effect. At the same time, when the elastic telescopic connecting rod drives the circular ring to reset, the liquid inside the hollow rod slowly flows back to the hollow tube through the circular ring, and the hollow rod slowly moves upward. The slow upward movement of the hollow rod will pull the rotating plate through the connecting rope, causing the rotating plate to slowly reset along with the hollow rod, thereby preventing the rotating plate from quickly resetting and causing uneven internal heat distribution, which affects the heat distribution and heating effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 3 One embodiment of the present invention is: a smart agricultural planting greenhouse based on the Internet of Things, comprising: a support frame 1, a film 2 is fixedly installed on the top of the support frame 1, a door curtain 3 is fixedly installed on the inner wall of the support frame 1, and a connecting plate 151 is fixedly installed on the inner wall of the support frame 1; a snow removal device, the snow removal device is arranged on the inner wall of the support frame 1, and the snow removal device includes a support plate 4, a temperature sensor 5, a heater 6, a motor 7, a reciprocating screw rod 8, a fixed rod 9, a threaded block 10, a fixed plate 11, an elastic telescopic rod 12, a snow removal rod 13 and a protrusion 14. In cold seasons, a relatively warm temperature can be maintained in the greenhouse to extend the growing season of crops. The support plate 4 is fixedly installed on the inner wall of the support frame 1 The temperature sensor 5 is fixedly mounted on the inner wall of the support frame 1, the heater 6 is fixedly mounted on the bottom of the connecting plate 151, the motor 7 is fixedly mounted on the surface of the support plate 4, the reciprocating screw rod 8 is fixedly mounted on the output end of the motor 7, the fixed rod 9 is fixedly mounted on the surface of the support plate 4, the threaded block 10 is threadedly mounted on the surface of the reciprocating screw rod 8, the fixed plate 11 is fixedly mounted on the surface of the threaded block 10, the elastic telescopic rod 12 is fixedly mounted on the top of the fixed plate 11, the snow removal rod 13 is fixedly mounted on the free end of the elastic telescopic rod 12, and the protrusion 14 is fixedly mounted on the surface of the support frame 1 to prevent the weight of the accumulated snow from being superimposed on the greenhouse structure, which may exceed the design load and increase the risk of deformation or even structural damage of the greenhouse.

[0028] The snow removal rod 13 contacts the surface of the film 2 to improve the snow removal effect. The temperature sensor 5 is electrically connected to the heater 6. The bump 14 contacts the surface of the snow removal rod 13 to prevent the film 2 from being scratched by generating vibration.

[0029] When the present embodiment is working, the real-time temperature in the greenhouse is detected by the temperature sensor 5. When the temperature is too low, the temperature sensor 5 will start the heater 6 to heat the greenhouse. In cold seasons, the greenhouse can maintain a relatively warm temperature, thereby extending the growing season of crops. At the same time, when it snows, the motor 7 is started, and the motor 7 rotates the reciprocating screw 8, which will drive the threaded block 10 to reciprocate, and the reciprocating motion of the threaded block 10 will drive the fixed plate 11 to reciprocate, and the reciprocating motion of the fixed plate 11 will drive the elastic telescopic rod 12 to reciprocate, and the reciprocating motion of the elastic telescopic rod 12 will drive the snow removal rod 13 to reciprocate, and the reciprocating motion of the snow removal rod 13 will push down the snow accumulated on the top of the film 2 to prevent the snow from being heavy.

At the same time, the retractability of the free end of the elastic telescopic rod 12 can be used to make the snow removal rod 13 always in contact with the film 2, thereby improving the snow removal effect. At the same time, the snow removal rod 13 will contact the protrusion 14 during the reciprocating motion. Through the contact between the snow removal rod 13 and the protrusion 14, the protrusion 14 will squeeze the snow removal rod 13 to move downward. The downward movement of the snow removal rod 13 will cause the free end of the elastic telescopic rod 12 to shrink. When the snow removal rod 13 is disengaged from the protrusion 14, the elastic telescopic rod 12 will drive the snow removal rod 13 to reset, and the snow removal rod 13 will contact the film 2 by shaking back and forth up and down, thereby preventing continuous contact with the film 2 and causing damage to the film 2, thereby affecting the thermal insulation effect.
