Description

Technical Field

[0001] This utility model relates to the field of planting supplemental lighting devices, and in particular to an automatic supplemental lighting device for plant seedlings. Background Technology

[0002] In southern my country, autumn and winter are often cloudy and rainy, resulting in low light intensity. Early spring is also often cloudy and rainy, with short periods of sunshine. In agricultural research and production, supplemental lighting can be used to promote plant growth. Indoor lighting can also be provided to ensure normal plant growth and meet the needs of urban families for indoor vegetable cultivation. In some special circumstances, such as preventing crops from being polluted by the external environment or attacked by pests and diseases, supplemental lighting devices can be used for isolation and protection to ensure the healthy growth of crops. For example, growing tents and other equipment can prevent plants from being affected by frost, pests, and diseases.

[0003] The main reasons for using supplemental lighting devices in crop cultivation include compensating for insufficient natural light, indoor vertical farming, and adapting to special environments. Supplemental lighting devices allow for the cultivation of more crops in a limited space through vertical farming.

[0004] Existing supplemental lighting devices can raise and lower the crop planting area via a control panel, but cannot raise and lower the supplemental lights. When hydroponically growing crops, raising and lowering the crops can cause water to overflow from the cabinet. The inability to adjust the position of the supplemental lights makes it difficult to provide adequate lighting for crops at different growth stages, which may lead to reduced growth efficiency due to insufficient photosynthesis. Therefore, a lifting cabinet with supplemental lights is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic supplemental lighting device for plant seedlings, which aims to improve the problem that the lack of adjustable position of the supplemental light in existing automatic supplemental lighting devices for plant seedlings leads to reduced crop growth efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic supplemental lighting device for plant seedlings, comprising a supplemental lighting device body, an internal lamp tube mounting bracket, a supplemental lighting lamp tube fixedly connected to the inner surface of the lamp tube mounting bracket, a control button on the surface of the supplemental lighting device body, a switch at the bottom of the control button, an automatic drum rotatably connected to the outer wall of the supplemental lighting device body via a mounting plate, a motor fixedly connected to the end of the automatic drum, a steel wire rope fixedly connected to the outer wall of the automatic drum, a fixing block fixedly connected to the surface of the supplemental lighting device body, a rotating shaft on the outer wall of the fixing block, a light-blocking cloth fixedly connected to the outer wall of the rotating shaft, and a spray assembly on the surface of the supplemental lighting device body.

[0008] The wire rope is wound around the outer wall of the automatic drum, and the end of the wire rope away from the automatic drum is fixedly connected to the top of the lamp mounting bracket.

[0009] As a further description of the above technical solution:

[0010] The lamp mounting bracket is arranged in a U-shape.

[0011] As a further description of the above technical solution:

A transmission pipe is fixedly connected to the inner wall of the lamp mounting bracket. A solenoid valve is fixedly connected to the end of the transmission pipe. A limit ring is fixedly connected to the outer wall of the main body of the supplementary lighting device.

[0013] As a further description of the above technical solution:

[0014] The end of the spray pipe furthest from the U-shaped pipe is inclined downwards.

[0015] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of an automatic supplemental lighting device for plant seedlings, comprising a supplemental lighting device body 1, with a lamp mounting bracket 2 arranged in a U-shape inside the body 1. Supplemental lighting lamps 3 are fixedly connected to the inner surface of the lamp mounting bracket 2, and five groups of supplemental lighting lamps 3 are arranged at equal intervals inside the lamp mounting bracket 2 to supplement the light source. The supplemental lighting lamps 3 can automatically start supplemental lighting time and intensity according to preset values ​​based on ambient light intensity, temperature, and humidity. The supplemental lighting time can be adjusted via Bluetooth. An environmental sensor module, including a photoresistor and a DHT11 temperature and humidity sensor, is fixed to the inner top of body 1. Its signal output is connected to the controller in the control box via wires. The control box is built into the side wall of the supplementary lighting device body 1. The microcontroller presets light intensity and humidity thresholds. When the environmental data is below the threshold, the microcontroller outputs a PWM signal to the LED driver circuit to adjust the brightness of the supplementary lighting tube 3. At the same time, it controls the start and stop of motor 8 and the on / off state of solenoid valve 20 through the relay module. A control button 4 is provided on the surface of the supplementary lighting device body 1. A switch 5 is provided at the bottom of the control button 4. The switch 5 is used to control the motor. The opening and closing of 8, and the rotation of control knob 4, adjust the winding degree of the automatic drum 7 driven by motor 8. The control box integrates an HC-05 Bluetooth module, which, after pairing with a mobile APP, receives user-set parameters such as supplementary lighting duration and irrigation cycle. Control knob 4 is a rotary encoder; its pulse signal is parsed by the microcontroller and converted into stroke commands for motor 8. The outer wall of the supplementary lighting device body 1 is rotatably connected to the automatic drum 7 via a mounting plate. The end of the automatic drum 7 is fixedly connected to the motor 8, and a steel wire rope 6 is fixedly connected to the outer wall of the automatic drum 7. The steel wire rope 6 is wound around the outer wall of the automatic drum 7. The end of the rope 6 away from the automatic drum 7 is fixedly connected to the top of the lamp tube mounting bracket 2. The steel wire rope 6 is forked near the lamp tube mounting bracket 2 and is used to connect to both ends of the lamp tube mounting bracket 2 to ensure the smooth lifting of the lamp tube mounting bracket 2. A fixing block 9 is fixedly connected to the surface of the supplementary lighting device body 1. A rotating shaft 10 is provided on the outer wall of the fixing block 9. A light-shielding cloth 11 is fixedly connected to the outer wall of the rotating shaft 10. There are two sets of light-shielding cloths 11, and the two sets of light-shielding cloths 11 are located on the left and right sides of the supplementary lighting device body 1, respectively. A set of fixing blocks 9 is provided at both ends of the rotating shaft 10 connected to each set of light-shielding cloths 11.

[0032] Reference Figures 2-4The surface of the supplementary lighting device body 1 is equipped with a spray assembly, which includes a U-shaped tube, spray pipes 18, a transmission pipe 19, a solenoid valve 20, and a limiting ring 21. The U-shaped tube is embedded inside the supplementary lighting device body 1, and several sets of spray pipes 18 are fixedly connected to the outside of the U-shaped tube. The spray pipes 18 are arranged in a U-shape around the top area of ​​the supplementary lighting device body 1 to avoid blocking light. The end of the spray pipe 18 away from the U-shaped tube is inclined downwards. Each set of spray pipes 18 is equipped with a valve on its surface to control the spray volume. The inner wall of the lamp mounting bracket 2 is fixedly connected to the transmission pipe 19, which is fixedly connected to the supplementary lighting device body 1. The end of the transmission pipe 19 is fixedly connected to the solenoid valve 20, which introduces tap water through an external pipe. The solenoid valve 20 controls the flow of water. To control the water inlet flow, the inlet of the solenoid valve 20 is connected to an external water source hose (not shown in the figure) via a quick-connect fitting, and the outlet is sealed to the transmission pipe 19 via a PVC rigid pipe to ensure a sealed water path during lifting and lowering. The solenoid valve 20 is controlled by a timer module (not shown in the figure), and each opening lasts for 10 seconds (adjustable). Combined with the fixed flow rate of the sprinkler pipe 18, it achieves single-quantity irrigation. The valves of each sprinkler pipe 18 are automatic ball valves used to adjust the regional water distribution. The outer wall of the supplementary lighting device body 1 is fixedly connected to a limit ring 21. Multiple limit rings 21 are provided, which are respectively sleeved on the outer walls of the transmission pipe 19 and the steel wire rope 6 to limit the transmission pipe 19 and the steel wire rope 6, so that they can operate normally while providing constraint to prevent the transmission pipe 19 and the steel wire rope 6 from becoming loose and interfering with each other.

[0033] Reference Figures 2-3 A fixing plate 14 is fixedly connected to the bottom of the light-shielding cloth 11. A magnetic sheet 15 is fixedly connected to the bottom of the fixing plate 14. A fixing magnet 16 is magnetically connected to the bottom of the magnetic sheet 15. The bottom of the fixing magnet 16 is fixedly connected to the lower end of the inner surface of the supplementary light device body 1. When the light-shielding cloth 11 is pulled down for use, the magnetic sheet 15 and the fixing magnet 16 are magnetically attracted, so that the light-shielding cloth 11 can remain flat when blocking light. A slot 12 is opened on the side wall of the fixing block 9. A coil spring 13 is fixedly connected to the inner wall of the slot 12. The movable end of the coil spring 13 is fixedly connected to the outer wall of the rotating shaft 10. When the light-shielding cloth 11 is not in use, the coil spring 13 restores its elasticity and drives the rotating shaft 10 to rotate, so as to roll up and store the light-shielding cloth 11.

[0034] Working principle: The plant is placed inside the main body 1 of the supplemental lighting device. When the ambient light intensity, temperature, or humidity sensor detects that the value is lower than the preset threshold, the supplemental lighting tube 3 automatically starts and adjusts the supplemental lighting time and intensity according to the set value. The user can also remotely adjust the supplemental lighting parameters via Bluetooth. The rotation of the control knob 4 can adjust the operation of the motor 8, thereby controlling the automatic drum 7 to raise and lower the steel wire rope 6. The forked steel wire rope 6 smoothly pulls the lamp mounting bracket 2 up and down to optimize the lighting position. When shading, the shading cloth 11 is pulled down to fix it. The magnetic sheet 15 at the bottom of the plate 14 is attracted to the fixed magnet 16 on the main body 1 of the supplementary lighting device to keep the cloth surface flat. After use, the coil spring 13 resets and drives the rotating shaft 10 to rotate and automatically roll back the light-blocking cloth 11 to the upper end of the main body 1 of the supplementary lighting device. When spraying, the solenoid valve 20 opens to allow the external water source to be transported to the loop pipe through the transmission pipe 19, and then distributed to several sets of spray pipes 18 to irrigate the seedlings. The spray volume is controlled by the valves of each spray pipe 18 and the solenoid valve 20. The limit ring 21 constrains the running trajectory of the transmission pipe 19 and the steel wire rope 6 to prevent interference.
