Description

Technical Field

[0001] This utility model relates to the field of supplemental lighting technology, specifically to an automatic supplemental lighting device for vertical cultivation. Background Technology

[0002] Vertical and efficient cultivation is an important direction for the development of solar greenhouses. It primarily achieves full utilization of production resources within limited space and creates higher economic value through changes in cultivation methods combined with advanced modern agricultural technologies. Vertical cultivation, a type of soilless vertical cultivation, involves constructing multi-layered structures using pipes or cultivation troughs, distributed in a gradient layered manner on a vertical plane. This expands traditional cultivation from a two-dimensional to a vertical space, making full use of facility space and natural light. Compared to two-dimensional cultivation, it can increase land use efficiency by 3-5 times and yield per unit area by 2-3 times. Furthermore, vertical planting is also appearing as a simplified planting method in urban and residential spaces, making full use of unused spaces such as underground passages, rooftops, and balconies for vegetable production. It also serves as an ecological landscape innovation, enriching people's lifestyles and fulfilling their spiritual needs.

[0003] However, due to the inherent structural characteristics of vertical cultivation, a drawback is that excessive layers or excessively tall plants can easily lead to insufficient light, especially in areas with insufficient sunlight and during periods of low light. In these conditions, light becomes a key factor limiting plant growth, making artificial lighting a necessary measure to improve the light environment for plant growth. Conventional supplemental lighting methods primarily involve overhead lighting, utilizing the existing support structure to suspend lights inside the roof, or constructing a support structure to hang lights 60-120cm above the cultivation layer. Timed or delayed supplemental lighting is then used to improve the light environment of the facility. However, existing methods have several problems: 1) Installing supplemental lighting over a large area significantly increases production and construction investment costs, leading to high pressure to recoup costs and even loss-making production; 2) It increases the structural load on facilities, and the complex light source circuits, coupled with proximity to flammable materials such as greenhouse film, pose high safety risks; 3) The structure of the light source itself can block natural light and affect the normal operation of equipment such as automatic sprinklers within the facility, creating a spatial obstruction effect; 4) When the light source is installed far away, the utilization efficiency of artificial light is low, resulting in light loss, while installing it too close makes sowing, harvesting, and other operations inconvenient. Furthermore, for vertical cultivation, conventional supplemental lighting methods cannot meet its light requirements, therefore, there is an urgent need to develop supplemental lighting devices and methods specifically for vertical cultivation. Utility Model Content

[0004] The purpose of this invention is to provide an automatic supplemental lighting device for vertical cultivation in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses an automatic supplemental lighting device for vertical cultivation, including a frame. A cultivation board is vertically arranged on the front of the frame. A drive motor is arranged on the top of the frame. A side plate is arranged on both sides of the top of the frame. Two rollers are rotatably connected between the two side plates. The output end of the drive motor is connected to one of the rollers through a first transmission mechanism. A first sprocket is fixedly connected to each end of the roller. A first chain is wound around the top of the two first sprockets located at the same end of the roller. The two ends of the first chain are located on the front and back of the frame, respectively. The endpoints of the two first chains are connected by a counterweight. A plurality of supplemental lights are arranged between the two first chains. The supplemental lights are located on the front of the frame and face the cultivation board.

[0007] As a preferred technical solution, the first transmission mechanism includes a first pulley, a second pulley, and a conveyor belt. The output end of the drive motor is connected to the first pulley, the second pulley is fixedly connected to a roller shaft, and the conveyor belt is wound around the first pulley and the second pulley.

[0008] As a preferred technical solution, a protective cover is also provided on the top of the frame, and the drive motor, the roller shaft and the first sprocket are disposed inside the protective cover.

[0009] As a preferred technical solution, the back of the frame is provided with support legs.

[0010] As a preferred technical solution, the fill lights are arranged at equal intervals.

[0011] As a preferred technical solution, two drive motors are provided.

[0012] As a preferred technical solution, a second transmission mechanism is further provided between the two rollers. The second transmission mechanism includes a second sprocket respectively disposed on the two rollers and a second chain wound around the second sprocket.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] This invention addresses the issue that conventional supplemental lighting methods cannot meet the lighting requirements of vertical cultivation by providing a specialized supplemental lighting device for vertical cultivation. By placing the supplemental lights on the first chain suspended on the front of the frame, it can provide uniform and controllable artificial lighting to the plants according to the actual natural light conditions, avoiding waste of light sources. Furthermore, the position of the supplemental lights is adjustable vertically. When there is sufficient natural light, the supplemental lights can be moved upward to reduce the obstruction of natural light by the supplemental lighting equipment, thereby improving the plant's utilization efficiency of natural light, without affecting normal sowing and harvesting operations.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] like Figure 1-3As shown, this embodiment discloses an automatic supplemental lighting device for vertical cultivation, including a frame 1. A cultivation board 2 is vertically arranged on the front of the frame 1. Multi-layer cultivation troughs (not shown in the figure) are installed on the cultivation board 2. The cultivation troughs are used for planting plants. A drive motor 3 is arranged on the top of the frame 1. A side plate 4 is arranged on both sides of the top of the frame 1. Two roller shafts 5 are rotatably connected between the side plates 4. The output end of the drive motor 3 is connected to a roller shaft 5 through a first transmission mechanism 6. A first sprocket 7 is fixedly connected to both ends of the roller shaft 5. A first chain 8 is wound around the top of the two first sprockets 7 located at the same end of the roller shaft 5. The two ends of the first chain 8 are located on the front and back of the frame 1, respectively. The endpoints of the two first chains 8 are connected by a counterweight 9. The two ends of the first chain 8 are subjected to a downward pulling force, which allows the first chain 8 to fit tightly against the first sprocket 7. A plurality of supplemental lights 10 are arranged between the two first chains 8. The supplemental lights 10 are located on the front of the frame 1 and face the cultivation board 2.

[0023] The operating principle and usage process of this embodiment are as follows:

[0024] When natural light is sufficient, supplemental lighting is not needed. The supplemental lights 10 on the first chain 8 are retracted upwards to avoid blocking natural light. When natural light is insufficient and supplemental lighting is required, the operator can activate the drive motor 3 and the supplemental lights 10. Activation can be remote or manual. After the drive motor 3 starts, it drives a roller 5 to rotate via the first transmission mechanism 6. The first sprockets 7, fixed to both ends of the roller 5, rotate accordingly, causing the first chain 8 to move. The supplemental lights 10 move downwards and unfold to provide supplemental lighting to the plants in the cultivation trough. When supplemental lighting is no longer needed, or when it is necessary to operate on the plants in the cultivation trough, the drive motor 3 is reversed, causing the supplemental lights 10 to retract upwards, freeing up space.

[0025] Example 2

[0026] like Figure 3 As shown, this embodiment is based on embodiment one. Specifically, the first transmission mechanism 6 includes a first pulley 601, a second pulley 602, and a conveyor belt 603. The output end of the drive motor 3 is connected to the first pulley 601, which is fixedly connected to the output shaft of the drive motor 3. The rotation of the output shaft of the drive motor 3 drives the first pulley 601 to rotate. The second pulley 602 is fixedly connected to a roller shaft 5. The conveyor belt 603 is wound around the first pulley 601 and the second pulley 602. The rotation is transmitted to the second pulley 602 through the conveyor belt 603, which in turn causes the roller shaft 5 to rotate, and finally drives the first chain 8 to move.

[0027] Example 3

[0028] like Figure 4 As shown, this embodiment is based on Embodiment 1. Specifically, a protective cover 11 is also provided on the top of the frame 1, and the drive motor 3, roller shaft 5 and first sprocket 7 are located inside the protective cover 11. The protective cover 11 isolates the above components from the outside world to avoid damage to the transmission structure and affect its use.

[0029] Example 4

[0030] like Figure 1-2 As shown, this embodiment is based on embodiment one. Specifically, the back of the frame 1 is provided with support legs 12 to support the frame 1 and enhance its stability.

[0031] Example 5

[0032] like Figure 1 As shown, this embodiment is based on embodiment one. Specifically, several supplementary lights 10 are arranged at equal intervals to make the supplementary light uniform.

[0033] Example 6

[0034] like Figure 1-3 As shown, this embodiment is based on embodiment one. Specifically, there are two drive motors 3, which rotate synchronously to avoid insufficient output power from one motor.

[0035] Example 7

[0036] like Figure 1-3 As shown, this embodiment is based on the first embodiment. Specifically, a second transmission mechanism 13 is provided between the two roller shafts 5. The second transmission mechanism 13 includes a second sprocket 1301 respectively disposed on the two roller shafts 5 and a second chain 1302 wound around the second sprocket 1301. The transmission efficiency between the roller shafts 5 is further enhanced by the second transmission mechanism 13.

[0037] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
