Description

Technical Field

[0001] This utility model relates to the field of rice cultivation technology, specifically to a light regulation device for rice cultivation under adverse conditions. Background Technology

[0002] Light duration control is crucial for the growth and development of rice. At different growth stages, light duration control needs to be flexibly adjusted according to the actual situation to meet the optimal light requirements for rice growth. In the process of rice cultivation under adverse conditions, the requirement for light duration is even more important. Many existing glass greenhouses or film greenhouses rely on the sun to illuminate the plants inside, but the light duration is not controllable. Moreover, if the plants are illuminated at night using light-emitting devices such as lamps, it will cause light pollution around the greenhouse and affect the rest of nearby residents. Therefore, there is an urgent need for a light regulation device for rice cultivation under adverse conditions. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a connecting frame and a light source, with two connecting frames suspended above the interior of the greenhouse, and a light source fixedly installed below the connecting frames;

[0005] It also includes:

[0006] The fixing frame consists of two frames, which are respectively fixedly installed on the front and rear sides of the outside of the greenhouse. The two fixing frames are rotatably connected by a first bidirectional lead screw through a bearing. A waterproof motor is fixedly installed on the front fixing frame, and the output shaft of the waterproof motor is connected to the front end of the first bidirectional lead screw.

[0007] The movable frame consists of two movable frames, both of which are movably installed on the outside of the greenhouse.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] like Figures 1-4 As shown, this embodiment adopts the following technical solution: it includes a connecting frame 1 and a light lamp 2. Two connecting frames 1 are suspended above the interior of the greenhouse 18, and a light lamp 2 is fixedly installed below the connecting frame 1.

[0026] It also includes:

[0027] The fixing frame 3 consists of two fixed frames, which are respectively fixedly installed on the front and rear sides of the outside of the greenhouse 18. The two fixing frames 3 are rotatably connected by a first bidirectional lead screw 4 through a bearing. A waterproof motor 5 is fixedly installed on the front fixing frame 3, and the output shaft of the waterproof motor 5 is connected to the front end of the first bidirectional lead screw 4.

[0028] Two movable frames 6 are movably installed on the outside of the greenhouse 18. A first bidirectional screw 4 is threaded through the two movable frames 6. Guide rods 7 are fixedly connected to the left and right sides between the two fixed frames 3. The guide rods 7 are movably installed through the two movable frames 6. A rain cover 11 is connected between the two fixed frames 3. The rain cover 11 is located above the first bidirectional screw 4 and the movable frames 6. The rain cover 11 can protect the first bidirectional screw 4 and prevent rainwater from dripping directly onto the first bidirectional screw 4.

[0029] Two folding covers 8 are fixedly installed on the opposite side walls of two fixed frames 3 respectively, and one end of the folding cover 8 is fixedly connected to the movable frame 6. The greenhouse 18 is equipped with a synchronous adjustment mechanism 9 connected to the two connecting frames 1, and the synchronous adjustment mechanism 9 is connected to the first bidirectional lead screw 4.

[0030] The synchronization adjustment mechanism 9 includes:

[0031] The second bidirectional lead screw 9-1 is rotatably installed inside the greenhouse 18 via bearings. The rear ends of both the first bidirectional lead screw 4 and the second bidirectional lead screw 9-1 are fixedly fitted with sprockets 9-2. The two sprockets 9-2 are connected by a chain 9-3. The chain 9-3 and the two sprockets 9-2 are covered with a protective cover 10, which is fixedly installed on the rear fixing frame 3 and the rear side wall of the greenhouse 18. The protective cover 10 can provide fold protection for the chain 9-3 and the sprockets 9-2, thereby improving the service life of the chain 9-3 and the sprockets 9-2.

[0032] There are two crossbars 9-4, which are fixedly installed inside the greenhouse 18 on the left and right sides of the second bidirectional screw 9-1. The connecting frame 1 is movably sleeved on the two crossbars 9-4. The pitch of the second bidirectional screw 9-1 is smaller than the pitch of the first bidirectional screw 4.

[0033] Example 2:

[0034] like Figure 3 and Figure 4 As shown, a further improvement is made based on embodiment 1: two connecting rods 12 are hinged to the upper part of the lamp 2, and a sliding block 13 is hinged to one end of the connecting rod 12. The two sliding blocks 13 are respectively slidably arranged in two sliding grooves 14 opened at the bottom of the connecting frame 1. A spring 15 connected to the sliding block 13 is fixedly arranged in the sliding groove 14. A pull rope 16 is fixedly arranged on the lamp 2. By pulling the pull rope 16 downward, and with the cooperation of the connecting rods 12, sliding blocks 13 and springs 15, the lamp 2 can be moved down to a lower position inside the greenhouse 18, making it easier to maintain the lamp 2. A sliding rod 17 is fixedly arranged in the sliding groove 14. The sliding block 13 and the spring 15 are movably sleeved on the sliding rod 17. The sliding rod 17 can not only provide auxiliary guidance for the sliding of the sliding block 13, but also prevent the spring 15 from bending when compressed, thus affecting its service life.

[0035] When using this invention, the waterproof motor 5 can be started, which drives the first bidirectional lead screw 4 to rotate, causing the two movable frames 6 to move synchronously in opposite directions and folding the two folding covers 8 to allow sunlight to pass through the greenhouse 18 and shine on the cultivated rice. During this process, through the transmission of the sprocket 9-2 and chain 9-3, the second bidirectional lead screw 9-1 can also be driven to rotate synchronously, causing the two connecting frames 1 to move synchronously in opposite directions. The two connecting frames 1 respectively drive the two light lamps 2 to move towards the front and rear sides inside the greenhouse 18, preventing the connecting frames 1 and light lamps 2 from blocking the rice inside the greenhouse 18. Even if it is still daytime, but the rice has reached the appropriate light exposure time for its cultivation period... The waterproof motor 5 can drive the first bidirectional screw 4 to reverse, so that the two moving frames 6 on both sides move synchronously in opposite directions. After the two moving frames 6 on both sides collide, the two folding covers 8 on both sides will be in the unfolded state and block the outside of the greenhouse 18. With the cooperation of the sprocket 9-2, chain 9-3 and the second bidirectional screw 9-1, the two connecting frames 1 on both sides can move synchronously in opposite directions. The two connecting frames 1 drive the two light lamps 2 to move closer. If it is night, but the rice has not reached the appropriate light time for its cultivation period, the light lamps 2 can be turned on to continue to illuminate the rice. In this process, by blocking the outside of the greenhouse 18 through the folding covers 8, light pollution on the outside of the greenhouse 18 can be avoided, which will affect the rest of the surrounding residents.

[0036] When maintenance of the lamp 2 is required, the pull rope 16 can be pulled down. The pull rope 16 moves the lamp 2 downward, causing the connecting rod 12 to flip and drive the sliding block 13 to move in the slide groove 14, thereby compressing the spring 15 and lowering the height of the lamp 2 in the greenhouse 18, making the maintenance of the lamp 2 more convenient.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] With the cooperation of No. 1 bidirectional lead screw 4, waterproof motor 5, moving frame 6, guide rod 7 and folding cover 8, not only can the isolation and control of the light of rice in greenhouse 18 be achieved during the day as needed, but also when the rice is illuminated at night, light pollution outside greenhouse 18 can be avoided.

[0039] With the cooperation of the synchronous adjustment mechanism 9, the position of the light lamp 2 can be synchronously controlled when the folding cover 8 is unfolded or folded. This not only avoids the rice from being blocked by the light lamp 2 and the connecting frame 1 during the day, but also ensures that the light lamp 2 can be in a good lighting position inside the greenhouse 18 when the rice needs to be illuminated at night.

[0040] By using the combination of the pull rope 16, the connecting rod 12, the sliding block 13 and the spring 15, the light lamp 2 can be moved down to a lower position inside the greenhouse 18, making the maintenance of the light lamp 2 more convenient.

[0041] The slide bar 17 not only provides auxiliary guidance for the sliding of the slide block 13, but also prevents the spring 15 from bending during compression, thus affecting its service life.

[0042] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
