Description

Technical Field

[0001] This utility model relates to the field of seedling bed technology, and in particular to an intelligent temperature-controlled greenhouse seedling bed using a graphene heating film. Background Technology

[0002] In the development of modern agriculture, greenhouse seedling cultivation, as a key link in improving crop yield and quality, places higher demands on the precise control of the seedling environment. Temperature, as a core environmental factor affecting seedling growth and development, directly determines the survival rate and robustness of seedlings through its effective control. Currently, traditional greenhouse seedling beds generally use water-heated pipes for heating. While water-heated pipe heating can achieve a certain degree of temperature diffusion, the equipment is complex to install, costly, and has a slow heating rate, making it difficult to quickly respond to changes in ambient temperature, resulting in low energy efficiency. Therefore, this application proposes a greenhouse seedling bed that can achieve uniform heating and automatic temperature control. Utility Model Content

[0004] This application provides an intelligent temperature-controlled greenhouse seedling bed using a graphene heating film, comprising:

[0005] Support legs, at least four support legs are provided, and support rods are fixedly connected between the support legs that are parallel to each other on the left and right sides.

[0006] The seedling bed consists of a base, a frame, and seedling trays. The base is composed of at least seven base rods, two of which are slidably connected to the grooves of two parallel limiting seats on the left and right sides. The frame is fixed to the top of the base by bolts and is made of four base plates welded together. The bottom of the frame extends inward by 5-7cm on all four sides. The seedling trays are welded and fixed to the inner wall of the bottom of the frame and are arranged in a grid pattern.

[0007] The heating plate is fixedly connected to the bottom of the frame and is located below the seedling tray. The heating plate includes a graphene heating film. A waterproof layer is fixedly wrapped around the outside of the graphene heating film. The waterproof layer uses a nano-coating material, which can protect the graphene heating film without affecting its thermal conductivity.

[0008] The control box is fixedly connected to one side of the frame and is used for automatic heating control of the heating plate.

[0009] The heating plates are further tilted downwards on both sides, leaving a gap between them and the bottom of the frame.

[0010] The control box further includes a controller and a battery pack. The controller is connected to the battery pack via wires, and the battery pack is connected to the graphene heating film via wires.

[0027] Example 1

[0028] Please see Figure 1-8 A smart temperature-controlled greenhouse seedling bed using a graphene heating film includes a support leg 10 and a seedling bed set on top of the support leg 10.

[0029] At least four support legs 10 are provided. Support rods 11 are fixedly connected between the support legs 10 that are parallel to each other on the left and right sides. Two parallel limiting seats 12 are fixedly connected to the support rods 11. The top of the limiting seats 12 is flush with the top of the support legs 10. A sliding groove is opened on the top of the limiting seats 12. Two parallel rotating rods 14 are placed on the top of the support rods 11. The rotating rods 14 are located between the support legs 10 and the limiting seats 12.

[0030] The seedling bed consists of a base 13, a frame 20, and a seedling tray 21. The base 13 consists of at least seven base rods, two of which are slidably connected to the sliding grooves of two parallel limiting seats 12 on the left and right sides. The top of the rotating rod 14 is in contact with the bottom of the base rod, and the rotation of the rotating rod 14 can provide the power for the base 13 to slide left and right. The frame 20 is fixedly connected to the top of the base 13 by bolts. The frame 20 is welded together from four base plates. The bottom of the frame 20 extends inward by 5-7cm on all four sides to provide installation space for the seedling tray 21. The seedling tray 21 is welded and fixed to the inner wall of the bottom of the frame 20. The seedling tray 21 is set in a grid pattern.

[0031] When the seedling bed is located at the top of the rotating rod 14, the length of the rotating rod 14 should be longer than the frame 20 to facilitate the rotation of the rotating rod 14 later.

[0032] A heating plate 40 is fixedly connected to the bottom 20 of the frame, located below the seedling tray 21. The heating plate 40 heats the seedling tray 21, providing a stable and suitable growth temperature environment for the seedlings, which is beneficial to improving the uniformity of seedling growth and survival rate. The heating plate 40 includes a graphene heating film, which is a new type of heating element using graphene material. It has the advantages of high heating efficiency, uniform heating, and good flexibility. Its heating principle utilizes the high electrical conductivity and excellent thermal conductivity of graphene. After being energized, the current passes through the graphene material to generate heat. A waterproof layer is fixedly wrapped around the outside of the graphene heating film. The waterproof layer uses a nano-coating material, which can protect the graphene heating film without affecting its thermal conductivity. An insulation layer is fixedly connected to the bottom outer wall of the waterproof layer. The insulation layer uses high-efficiency insulation materials, such as polyurethane foam or rock wool. Its function is to reduce heat loss downwards, improve heat utilization, and allow heat to be mainly transferred upwards to the seedling tray, providing a suitable growth temperature for the seedlings.

[0033] The heating plate 40 is tilted downwards on both sides, and there is a gap between it and the bottom of the frame 20 so that when watering the seedlings, excess water can flow outwards along both sides of the heating plate 40 to avoid water accumulation on the heating plate 40.

[0034] A control box 30 is fixedly connected to one side of the frame 20. The control box 30 contains a controller and a battery. The controller is connected to the battery via wires. The controller uses a microprocessor and has data processing and logic control functions. The battery is connected to the graphene heating film via wires to provide power to the graphene heating film. The control box 30 is also equipped with a control switch, which is connected to the controller and the battery via wires. A wire hole is also reserved on one side of the control box 30 to facilitate the connection of the battery to an external power source.

[0035] Multiple temperature sensors are evenly installed on the seedling tray 21. The temperature sensors are connected to the controller via wires to monitor the temperature of the seedling tray 21 in real time and transmit the temperature data to the controller.

[0036] Water guide plates 50 are symmetrically arranged on the left and right sides of the bottom of the frame 20. The water guide plates 50 are detachably installed on the bottom of the frame 20 by bolts and are located below the heating plate 40. Two support columns 51 are fixedly connected to the side of the water guide plate 50 away from the bolts. When the water guide plate 50 is installed on the bottom of the frame 20 by bolts, the support columns 51 abut against the frame edge of the bottom of the frame 20, so that the water guide plate 50 is in a downward tilted state, so that the water flowing from the heating plate 40 can flow down the water guide plate 50 to the ground.

[0037] In actual operation of this embodiment, the seedling bed is placed in a greenhouse for seedling cultivation. The temperature sensor monitors the temperature of the seedling tray 21 in real time and transmits the temperature data to the controller. After receiving the temperature data from the temperature sensor, the controller compares it with the preset temperature range. When the actual temperature is lower than the preset lower limit, the controller issues a command to activate the battery block to start heating the graphene heating film. When the actual temperature reaches the preset upper limit, the controller issues a command to deactivate the battery block to stop heating the graphene heating film, thereby achieving automatic control of the seedling bed temperature.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
