Description

Technical Field

[0001] This utility model belongs to the technical field of strawberry seedling sheds, and in particular relates to an adjustable shading device for strawberry seedling sheds. Background Technology

[0002] Light management is crucial for cultivating healthy strawberry seedlings. Strawberries are light-loving plants, but their light requirements vary significantly at different growth stages. During seed germination, a low-light environment of 12-14 hours per day is necessary, with a light intensity of 1000-1500 lux. Excessive direct sunlight at this stage can inhibit radicle development. Once the seedlings have developed 2-3 true leaves, the light intensity should be gradually increased to 14-16 hours per day, with an intensity of around 20,000 lux. The photosynthetic efficiency at this stage directly affects carbohydrate accumulation in the plant; full-spectrum LED supplemental lighting is recommended, with a blue-to-red light ratio of 1:3 being ideal to promote leaf expansion and prevent excessive vegetative growth. In the early flower bud differentiation stage (approximately day 30-45 of seedling cultivation), shortening the day length to 8-10 hours can induce flower bud formation. Combining this with a low-temperature treatment of 10-15℃ at this time yields even better results. In actual production, a segmented lighting strategy is recommended: provide natural light from 6-10 am, supplement with artificial light in the afternoon to maintain a stable light intensity, and gradually reduce the light intensity one hour before dusk to simulate the natural light decay process. This dynamic regulation can significantly improve the seedling vigor index and increase root vitality by more than 40%.

[0003] Comparing with Chinese Patent CN213840766U, a vegetable seedling greenhouse with adjustable light intensity is disclosed. It includes a cultivation support base, a greenhouse body fixedly mounted on the support base, a roof inclinedly mounted on the top of the greenhouse body, and an adjustment frame fixedly mounted on the top of the greenhouse body. The adjustment frame has symmetrically arranged adjustment cavities one and two. Each adjustment cavity one and cavity two contains several rotating shafts one and two, respectively. The two ends of each rotating shaft one and shaft two are respectively connected by convex gears one and two, which mesh head-to-tail. Shading cloth is fitted over the outer sides of each rotating shaft one and shaft two, and a load-bearing plate is provided at the bottom of the shading cloth. This achieves adjustable light intensity within the greenhouse to meet the needs of vegetable seedling production, and the load-bearing plate secures the shading cloth.

[0004] However, since the above-mentioned patent provides shade from top to bottom, all the shade cloths can only be lowered at noon when the sun is strong, which reduces the amount of sunlight the strawberry seedlings receive and seriously affects their sunlight exposure. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable shading device for strawberry seedling sheds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable shading device for a strawberry seedling greenhouse includes a greenhouse body assembly for cultivating strawberry seedlings, and a spray assembly for lighting and irrigation installed on the top of the greenhouse body assembly. A dimming assembly for adjusting sunlight exposure by inflating and raising / lowering the greenhouse body assembly is installed on the sun-facing side of the greenhouse body assembly. The greenhouse body assembly includes a greenhouse main body with an entrance / exit at one end, a ventilation mechanism on the main body, a solar panel on the top of the main body, and a battery behind the solar panel. The spray assembly includes a water spraying mechanism for evenly spraying water, with several lights evenly distributed in the center of the spraying mechanism. The dimming assembly includes a wall mechanism for light transmission and sealing protection, with a shading airbag in the center of the wall mechanism. A counterweight is installed at the top of the shading airbag, and an inflation / deflation mechanism for gas inlet / outlet is installed at one end of the shading airbag.

[0008] Furthermore, the ventilation mechanism includes ventilation fans and ventilation windows installed at both ends of the main body of the greenhouse.

[0009] Furthermore, the solar panel and the battery are respectively bolted to the top of the main body of the greenhouse.

[0010] Furthermore: the water spraying mechanism includes a water distribution frame, a plurality of water spray nozzles are evenly installed at the bottom of the water distribution frame, a water inlet pipe is installed at the rear end of the water distribution frame, and a water inlet valve is installed on the water inlet pipe.

[0011] Furthermore, the spray nozzle and the water inlet pipe are respectively connected to the water distribution frame via sealing threads.

[0012] Furthermore: the wall structure includes a fixed frame, with transparent glass installed at the front and back of the fixed frame respectively; the inflation / deflation mechanism includes an air pump, with a filter head installed at the air inlet end of the air pump, an air outlet pipe provided below the air pump, and an air outlet valve installed on the air outlet pipe.

[0013] Furthermore, the air pump and the air outlet pipe respectively pass through the fixed frame and are connected to the light-shielding airbag pipeline.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The shading airbag can be expanded to completely block sunlight under the action of the air pump (the counterweight limit ensures stability). After the air is deflated, the counterweight will automatically pull down to restore light transmission. Even at noon when the sun is strong, it can be raised halfway to provide partial shading for strawberry seedlings, thereby increasing the light exposure time for strawberry seedlings.

[0016] 2. During the strawberry seedling stage, the system can achieve full sunlight in the morning to promote photosynthesis, intelligent shading (airbag expansion) at noon to avoid damage from high temperature and strong light, and automatic irrigation and supplemental lighting in the evening for full-cycle management. Compared with traditional greenhouse seedling cultivation, the survival rate is increased by 35% and the seedling cycle is shortened by about 20%.

[0017] 3. The transparent glass double-sided encapsulation design not only ensures basic lighting needs, but also allows for stepless adjustment of light transmittance (0-100% adjustable) through the expansion of the airbag. Combined with a light sensor (expandable), it can achieve precise matching of light for different growth stages of strawberry seedlings, reducing the problems of strong light scorching or weak light etiolation.

[0018] 4. Using air as the shading medium (the filter head ensures the air is clean), it has the advantages of zero material aging and loss and no maintenance of mechanical transmission parts compared with traditional sunshade cloth. Moreover, the volume of the airbag after shrinking is only 15% of the expanded state, minimizing the obstruction of natural light. Attached Figure Description

[0029] In this embodiment: the spraying assembly includes a water spraying mechanism for uniformly spraying water, with several lights 205 evenly distributed in the middle of the water spraying mechanism; the water spraying mechanism includes a water distribution frame 201, with several spray nozzles 202 evenly installed at the bottom of the water distribution frame 201, and a water inlet pipe 204 installed at the rear end of the water distribution frame 201, with a water inlet valve 203 installed on the water inlet pipe 204; the spray nozzles 202 and the water inlet pipe 204 are respectively connected to the water distribution frame 201 by sealing threads; the lights 205 emit light to ensure illumination in dark conditions, and the water inlet valve 203 controls the water to enter the water distribution frame 201 from the water inlet pipe 204 and spray onto the strawberry seedlings through the spray nozzles 202 for irrigation;

[0030] In this embodiment: the dimming component includes a wall mechanism for light transmission and enclosed protection. A light-shielding airbag 303 is disposed in the middle of the wall mechanism, a counterweight 304 is disposed at the top of the light-shielding airbag 303, and an inflation / deflation mechanism for gas inlet and outlet is disposed at one bottom end of the light-shielding airbag 303.

The fixed frame 301 supports the transparent... Glass 302 blocks the sunny side of the main body 101 of the greenhouse. When sunlight is needed, the vent valve 308 opens the vent pipe 307, and the counterweight 304 presses down on the shading airbag 303 under the action of gravity, so that the gas in the shading airbag 303 is discharged from the vent pipe 307. Sunlight passes through the transparent glass 302 and shines into the main body 101 of the greenhouse. When sunlight needs to be blocked, the air pump 305 draws clean air through the filter head 306 and injects it into the shading airbag 303, causing the shading airbag 303 to expand. Under the restriction of the transparent glass 302 on both sides, it pushes the counterweight 304 up to block the sunlight.
