Description

Technical Field

[0001] This utility model belongs to the technical field of greenhouse equipment for wheat cultivation, specifically relating to a timed control facility for greenhouse light for four generations of wheat cultivation per year. Background Technology

[0002] The four-generation wheat cultivation method involves precise artificial environmental control of light, temperature, and humidity. Wheat germinates by soaking in water at 25℃, then is transplanted into seed trays with nutrient soil. Once the wheat reaches the two-leaf stage, it is moved to a vernalization box. After vernalization, the wheat is transferred to flowerpots with a light setting of 14 hours daytime / 10 hours darkness, and a light intensity of 500 μmol / m². 2 In an environment with a daytime temperature of 22℃ and a nighttime temperature of 15℃, wheat undergoes seedling, tillering, jointing, and heading stages in approximately 25-30 days. During this period, watering is applied appropriately based on soil conditions, and weeding, loosening the soil, and fertilization are carried out regularly. This method breaks the limitations of the natural growth cycle of wheat, enabling efficient breeding for continuous multi-generational propagation throughout the year.

[0003] Traditional wheat greenhouse cultivation commonly uses fixed supplemental lighting, such as high-pressure sodium lamps and fluorescent lamps, suspended from the roof. While this alleviates insufficient natural light, it has several drawbacks. Not only is energy consumption high, but artificial light sources are entirely dependent on the power grid, resulting in heavy electricity costs over the long term. Furthermore, relying solely on suspended supplemental lighting cannot achieve the high-intensity, customizable lighting management required for four generations of wheat cultivation per year, especially in high-latitude, short-day regions. Existing photovoltaic panels and lighting fixtures are installed separately, lacking integrated structural design and cumbersome operation. There is an urgent need for an energy-efficient, self-supplied, and easy-to-operate greenhouse lighting system to support the industrial-scale needs of rapid wheat propagation. Therefore, this paper proposes a timed lighting control facility for greenhouses cultivating four generations of wheat per year. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1-3 As shown, a timed light control system for a greenhouse that grows wheat for four generations a year includes a foundation 1, a greenhouse frame 2 on top of the foundation 1, and a transparent heat insulation film 3 covering the greenhouse frame 2. The foundation 1 supports the overall greenhouse structure, ensuring wind pressure resistance and stability. It adopts a concrete strip foundation, with pre-embedded anchor bolts welded to the greenhouse frame 2. The transparent heat insulation film 3 covering the greenhouse frame 2 forms a closed growth space, balancing light transmission and heat preservation. The greenhouse frame 2 is made of hot-dip galvanized square steel pipe, and the transparent heat insulation film 3 is a PO coated film. The edges of the film are fixed by aluminum alloy slots and sealing strips.

[0023] The greenhouse frame 2 has doors 4 on its front and rear sides, which facilitate access to the greenhouse for daily management, equipment maintenance, and emergency response. Each door 4 has a handle 5, providing an ergonomic point of force for easy opening and closing. A hoisting rope 6 is installed on the inner top wall of the greenhouse frame 2, with a lighting lamp 7 at its bottom. The ceiling lighting lamp 7 is a high-pressure sodium lamp, providing illumination from above.

[0024] A fixing seat 8 is provided on the outer wall of the greenhouse frame 2. The fixing seat 8 secures the sliding shaft 12 when the sliding plate 10 is upright. A sliding guide rail 9 is provided on the outer side of the greenhouse frame 2. The sliding guide rail 9 enables the sliding plate 10 to switch between horizontal and vertical states. The sliding guide rail 9 is made of anodized aluminum alloy. A sliding plate 10 is provided on the sliding guide rail 9. A handle 11 is provided on the top of the sliding plate 10, which facilitates pulling up the front end of the sliding plate 10. Sliding shafts 12 are provided at both ends of the sliding plate 10. A slot 13 is provided at the front end of the sliding guide rail 9. The slot 13 facilitates the removal of the front sliding shaft 12 and locks the bottom end of the sliding plate 10 after it is upright to prevent the sliding shaft 12 from derailing.

[0025] The specific design of the aforementioned key components will be discussed in detail below:

[0026] The sliding plate 10 has a three-layer composite structure, consisting of a solar panel, an energy storage battery, and an LED light-emitting sheet from top to bottom. The LED light-emitting sheet is electrically connected to the energy storage battery via wires. The solar panel is a monocrystalline silicon solar panel that collects solar energy during the day. The energy storage battery is a lithium iron phosphate battery that stores electrical energy. The LED light-emitting sheet is a full-spectrum LED. An MPPT controller is installed between the solar panel and the battery to control the charging efficiency.

[0027] The slot 13 at the front end of the sliding guide rail 9 has a U-shaped structure, and the width of the slot 13 matches the diameter of the sliding shaft 12. The sliding plate 10 slides along the guide rail and rotates vertically to stand up. From the retracted state to the position of the supplementary light, it can be operated by a single person. The side wall of the fixed base 8 is symmetrically provided with spring beads. The spring beads are made of 304 stainless steel beads and silicon manganese springs, which are locked after the sliding shaft 12 is engaged when the sliding plate 10 is upright.

[0028] It also includes a remote control 14, which communicates remotely with the LED light-emitting sheet and the lighting lamp 7. The LED light-emitting sheet provides close-range supplemental lighting outside the greenhouse, complementing the lighting from the lighting lamp 7. The remote control 14 controls the on / off state and brightness of both, and presets the light cycle mode.

[0029] The solar panel is electrically connected to the energy storage battery, which is equipped with a charging port. The MPPT controller optimizes the output power of the solar panel in real time to prevent overcharging of the battery. The battery has a built-in BQ76940 overcharge / over-discharge chip, a temperature sensor, and a fuse. The charging port supports external power supply to replenish the energy storage battery.

[0030] The fixing seats 8 are symmetrically arranged on both sides of the greenhouse frame 2, and the number of fixing seats 8 corresponds to the number of sliding guide rails 9. Multiple sliding plates 10 are set on multiple sliding guide rails 9 to achieve a scattered distribution at different positions, reducing the weight of a single sliding plate 10 and facilitating operation. Each sliding plate 10 is fixed by a corresponding number of fixing seats 8.
