[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a light control system suitable for facility agriculture, including a greenhouse 1, a transmission mechanism 2 is provided in the inner cavity of the greenhouse 1, and a shading mechanism 3 is provided on one side of the transmission mechanism 2.

[0029] The transmission mechanism 2 includes a drive bevel gear 203, a universal joint transmission rod 204, and an upper lead screw 206. A second bevel gear 207 is fixedly installed on one side of the upper lead screw 206, and a first bevel gear 205 is provided at both ends of the universal joint transmission rod 204.

[0030] Specifically, when the driving bevel gear 203 is driven to rotate, it can simultaneously drive the first bevel gear 205 and the second bevel gear 207 to rotate. The first bevel gear 205 drives the universal joint transmission rod 204 to rotate. When the first bevel gear 205 is driven to rotate by the driving bevel gear 203, the first bevel gear 205 on the opposite side rotates in the opposite direction. The thread of the side lead screw 208 on the opposite side of the side lead screw 208 is the reverse thread. Since universal joints are provided at both ends of the universal joint transmission rod 204, the universal joint transmission rod 204 can change the bending direction of the output.

[0031] The transmission mechanism 2 also includes a connecting block 201 and a side lead screw 208. A motor 202 is fixedly installed inside the connecting block 201, and a drive bevel gear 203 is fixedly installed at the output end of the motor 202.

[0032] Specifically, the operation of the control motor 202 can drive the active bevel gear 203 to rotate, thereby driving the first bevel gear 205 and the second bevel gear 207 to rotate, and the power is distributed for output.

[0033] A third bevel gear 209 is fixedly installed at one end of the side lead screw 208, and the third bevel gear 209 meshes with the first bevel gear 205 at the other end of the universal joint transmission rod 204.

[0034] Specifically, when the first bevel gear 205 and the third bevel gear 209 are meshed, the rotation of the first bevel gear 205 can drive the third bevel gear 209 to rotate, thereby changing the output direction of the power.

[0035] The driving bevel gears 203 are meshed with the second bevel gear 207 and the first bevel gear 205, and the universal joint transmission rods 204 are arranged on both sides of the driving bevel gears 203.

[0036] Furthermore, the operation of the control motor 202 is controlled. The output end of the motor 202 drives the active bevel gear 203 to rotate, thereby driving the two first bevel gears 205 and one second bevel gear 207 to rotate. The rotation of the universal joint transmission rod 204 drives the first bevel gear 205 at the other end to rotate, thereby driving the third bevel gear 209 to rotate, and then driving the side lead screw 208 to rotate. Since the two first bevel gears 205 rotate in opposite directions, and since the two side lead screws 208 have opposite threads, when the side lead screws 208 on both sides of the canopy 1 and the upper lead screw 206 on the top of the canopy 1 rotate simultaneously, the positions of the components in the shielding mechanism 3 can be changed.

[0037] Example 2

[0038] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a blocking mechanism 3 capable of changing the light intensity.

[0039] The shielding mechanism 3 includes a symmetrically arranged U-shaped frame 302 and a fixing strip 304, and a U-shaped baffle 301 is provided on the opposite side of the fixing strip 304.

[0040] Specifically, by sliding the U-shaped baffle 301 to change the distance between the U-shaped frame 302 and the fixing strip 304, the light can be controlled to shine into the shed 1.

[0041] The shielding mechanism 3 also includes a fixing plate 305, a U-shaped frame 302, and a number of sliding rods 303 on the opposite side of the fixing strip 304.

[0042] The fixing strip 304 is fixedly installed on the top of the fixing plate 305. The U-shaped baffle 301 is slidably sleeved on the outside of several sliding rods 303. The two side screw rods 208 and the upper screw rod 206 are all connected to the U-shaped baffle 301 through threaded sleeves.

[0043] Specifically, the U-shaped baffle 301 can be driven to slide on the outside of several sliding rods 303 by the action of an upper lead screw 206 and two side lead screws 208, thereby changing the intensity of light entering the greenhouse 1.

[0044] Furthermore, when the U-shaped baffle 301 slides on several sliding rods 303, the intensity of light entering the shed 1 can be changed by adjusting the distance between the U-shaped baffle 301 and the U-shaped frame 302 and the fixing strip 304.

[0045] Working principle: The connecting block 201 is fixedly installed on one side of the inner surface of the shed body 1. The two first bevel gears 205 and one second bevel gear 207 are not in contact, controlling the operation of the motor 202. The output end of the motor 202 drives the active bevel gear 203 to rotate. Because the universal joint transmission rod 204 is fixedly installed on the inner side of the shed body 1 through several fixing blocks, the upper lead screw 206 and the two side lead screws 208 are all connected to the inner side of the shed body 1 through fixing blocks. The active bevel gear 203 drives the two first bevel gears 205 and one second bevel gear 207 to rotate. The threads of the upper lead screw 206 can drive the U-shaped baffle 301 towards the motor 202. When the universal joint drive rod 204 rotates, it drives the first bevel gear 205 at the other end to rotate, which in turn drives the third bevel gear 209 to rotate, and then drives the side lead screw 208 to rotate. When the second bevel gear 207 rotates, it drives the upper lead screw 206 to rotate. Under the action of one upper lead screw 206 and two side lead screws 208, the U-shaped baffle 301 can slide on several sliding rods 303. By adjusting the distance between the U-shaped baffle 301 and the U-shaped frame 302 and the fixing strip 304, the intensity of light entering the shed 1 can be changed. By adjusting the position of the two U-shaped baffles 301, the intensity of light entering the shed 1 can be changed.

[0046] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
