[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a greenhouse solar energy heat collection and dissipation device. It utilizes a greenhouse back wall, graphene heating panels, mounting components, black PVC plastic water pipes, a water inlet cover, a temperature display, a signal line, and a temperature sensor. During the day, sunlight shines directly through the greenhouse front wall onto the graphene heating panels and black PVC plastic water pipes. On one hand, the stationary, non-circulating water inside the black PVC plastic water pipes absorbs solar energy and converts it into heat. On the other hand, the graphene heating panels, while absorbing sunlight, convert it into heat, heating the black PVC plastic water. This allows the stored water to reach 65°C or higher during the day. At night, as the greenhouse temperature decreases, the black PVC plastic water pipes slowly and continuously release heat from the stored hot water, supplementing the greenhouse temperature and ensuring normal growth of organisms at night. Simultaneously, the temperature sensor collects the greenhouse temperature and transmits the signal to the temperature display via the signal line. The temperature display converts the signal into data for easy monitoring by users. This device not only solves the problems of high energy consumption and nighttime heat storage and insulation but also features a simple structure, requires minimal user intervention, and is highly practical.

[0017] 2. This utility model provides a greenhouse solar heat collection device. It utilizes a combination of a locking block, a fixing groove, a limiting groove, a spring, a sliding rod, clamping plates, and protective pads. During use, the operator first uses a self-drilling screw to fix the graphene heating plate to the rear wall of the greenhouse according to the dimensions. Then, the water inlet cap is rotated open, and water is injected into the black PVC plastic water pipe. The black PVC plastic water pipe is then pushed through the fixing groove on one side of the locking block, squeezing it between the clamping plates. This compresses the clamping plates, causing the sliding rod to slide along the inner wall of the limiting groove. Simultaneously, the spring contracts, pushing the clamping plates to press the black PVC plastic water pipe between the protective pads. The protective pads increase friction between the pipe and the protective pads, preventing the pipe from loosening and falling off. The construction process is simple, significantly shortening the greenhouse construction period, saving time and costs, and facilitating installation and disassembly.

[0018] 3. This utility model provides a greenhouse solar energy collection and heat dissipation device. It consists of a greenhouse front wall, a fixed base, a first fixed plate, a transmission rod, a rocker arm, a roller, a connecting belt, an insulation blanket, a motor, a transmission shaft, a transmission belt, a take-up roller, and a second fixed plate. During the day, when the sun is out, the user starts the motor, which drives the transmission shaft to rotate. The transmission shaft then drives the transmission belt, which in turn drives the take-up roller to rotate on the inner wall of the second fixed plate, rolling the insulation blanket onto the outer surface of the take-up roller. This allows sunlight to penetrate the greenhouse front wall and directly reach the graphene heating plate and the black PVC plastic water pipe. After sunset, the user cranks the rocker arm, which drives the transmission rod to rotate on the inner wall of the first fixed plate, causing the roller to rotate and rolling the connecting belt onto the outer surface of the roller, covering the top of the greenhouse front wall with the insulation blanket. The insulation blanket can be quickly uncovered and covered, saving manpower and demonstrating good application value. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-4 As shown, this utility model provides a greenhouse solar heat collection device, including a heat collection mechanism 1, with a heat preservation mechanism 2 installed on the top of the heat collection mechanism 1; the heat collection mechanism 1 includes a greenhouse rear wall 11, a graphene heating plate 12 is fixedly connected to one side of the greenhouse rear wall 11, an installation component 13 is fixedly connected to one side of the graphene heating plate 12, a black PVC plastic water pipe 14 is movably connected to the middle of the installation component 13, a water filling cap 15 is threadedly connected to the top of the black PVC plastic water pipe 14, a temperature display instrument 16 is fixedly connected to one side of the greenhouse rear wall 11, a signal line 17 is fixedly connected to the top of the temperature display instrument 16, a temperature sensor 18 is fixedly connected to one end of the signal line 17, and the temperature sensor 18 is fixedly connected to one side of the greenhouse rear wall 11.

[0027] In this embodiment, when the sun comes out during the day, it can shine directly onto the graphene heating plate 12 and the black PVC plastic water pipe 14 through the front wall 21 of the greenhouse. On the one hand, the fixed water in the black PVC plastic water pipe 14, which does not flow or circulate, absorbs solar energy and converts it into heat energy. On the other hand, when the graphene heating plate 12 absorbs sunlight, it converts it into heat energy, which heats the black PVC plastic water, so that the stored water can reach 65°C or above during the day. At night, when the temperature in the greenhouse decreases, the black PVC plastic water pipe 14 slowly and continuously releases heat through the hot water stored inside, which replenishes the temperature of the greenhouse and ensures that the organisms in the greenhouse can grow normally at night. At the same time, the temperature inside the greenhouse can be collected by the temperature sensor 18 and transmitted to the temperature display instrument 16 through the signal line 17. The temperature display instrument 16 converts the signal into data information for easy observation of the temperature inside the greenhouse by the user.

[0028] Example 2

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the mounting component 13 includes a locking block 131, a fixing groove 132 is provided in the middle of the locking block 131, a limiting groove 133 is provided in the inner wall of the fixing groove 132, a spring 134 is fixedly connected to the inner wall of the limiting groove 133, a sliding rod 135 is fixedly connected to one end of the spring 134, the outer wall of the sliding rod 135 is slidably connected to the limiting groove 133, a clamping plate 136 is fixedly connected to one end of the sliding rod 135, and a protective pad 137 is fixedly connected to one side of the clamping plate 136.

[0030] In this embodiment, the operator first uses a self-drilling screw to fix the graphene heating plate 12 to the back wall 11 of the greenhouse according to the size, then rotates to open the water filling cover 15 and injects water into the black PVC plastic water pipe 14. Then, the black PVC plastic water pipe 14 is squeezed into the clamping plate 136 through the fixing groove 132 opened on one side of the clamping block 131, so that the clamping plate 136 is subjected to the compressive force. The sliding rod 135 slides along the inner wall of the limiting groove 133, and the spring 134 contracts at the same time, pushing the clamping plate 136 to squeeze the black PVC plastic water pipe 14 between the protective pads 137. The protective pads 137 increase the friction between the black PVC plastic water pipe 14 and prevent the black PVC plastic water pipe 14 from loosening and falling off.

[0031] Example 3

[0032] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the insulation mechanism 2 includes a greenhouse front wall 21, one side of which is fixedly connected to the greenhouse rear wall 11. A fixed seat 22 is fixedly connected to the bottom of the greenhouse front wall 21. A fixed plate 23 is fixedly connected to one side of the fixed seat 22. A transmission rod 24 is rotatably connected to the inner wall of the fixed plate 23. A rocker arm 25 is fixedly connected to one end of the transmission rod 24. A roller 26 is fixedly connected to the outer wall of the transmission rod 24. A connecting belt 27 is fixedly connected to the outer wall of the roller 26. An insulation blanket 28 is fixedly connected to one end of the connecting belt 27. A take-up roller 212 is fixedly connected to one end of the insulation blanket 28. A second fixed plate 213 is rotatably connected to both ends of the outer wall of the take-up roller 212. A transmission belt 211 is sleeved on the outer wall of the take-up roller 212. A transmission shaft 210 is sleeved on the bottom of the inner wall of the transmission belt 211. A motor 29 is provided at one end of the transmission shaft 210. The output end of the motor 29 is fixedly connected to the transmission shaft 210.

[0033] In this embodiment, when the sun comes out during the day, the user starts the motor 29, which drives the transmission shaft 210 to rotate. The transmission shaft 210 drives the transmission belt 211 to move, and the transmission belt 211 drives the take-up roller 212 to rotate on the inner wall of the second fixed plate 213, so that the insulation blanket 28 is rolled up to the outer surface of the take-up roller 212, allowing the sun to shine directly on the graphene heating plate 12 and the black PVC plastic water pipe 14 through the greenhouse front wall 21. When the sun sets, the user shakes the rocker arm 25, which drives the transmission rod 24 to rotate on the inner wall of the first fixed plate 23, which drives the roller 26 to rotate, so that the connecting belt 27 is rolled up to the outer surface of the roller 26, so that the insulation blanket 28 covers the top of the greenhouse front wall 21.

[0034] The working principle of this greenhouse solar heat collection device will be explained in detail below.

[0035] like Figure 1-4As shown, during use, the operator first uses a self-drilling screw to fix the graphene heating plate 12 to the rear wall 11 of the greenhouse according to the dimensions. Then, the operator rotates to open the water inlet cap 15 and injects water into the black PVC plastic water pipe 14. The black PVC plastic water pipe 14 is then pushed into the clamping plates 136 through the fixing groove 132 on one side of the clamping block 131, so that the clamping plates 136 are subjected to compressive force. This causes the sliding rod 135 to slide along the inner wall of the limiting groove 133, causing the spring 134 to contract and push the clamping plates 136 to hold the black PVC plastic water pipe 14 in place. The insulation blanket 28 is pressed between the protective pads 137, increasing friction between the protective pads 137 and the black PVC water pipe 14 to prevent it from loosening and falling off. When the sun comes out during the day, the user starts the motor 29, which drives the drive shaft 210 to rotate. The drive shaft 210 then drives the drive belt 211, which in turn drives the take-up roller 212 to rotate on the inner wall of the fixed plate 213, winding the insulation blanket 28 onto the outer surface of the take-up roller 212, allowing sunlight to penetrate the greenhouse. The front wall 21 directly shines sunlight onto the graphene heating plate 12 and the black PVC plastic water pipe 14. On one hand, the stationary, non-circulating water inside the black PVC plastic water pipe 14 absorbs solar energy and converts it into heat energy. On the other hand, the graphene heating plate 12, when absorbing sunlight, converts it into heat energy, scorching the black PVC plastic water, allowing the stored water to reach 65°C or higher during the day. After sunset, the user cranks the lever 25, which in turn drives the transmission rod 24 to rotate on the inner wall of the fixed plate 23, thus driving the roller 2. 6. Rotate to rewind the connecting belt 27 to the outer surface of the roller 26, so that the insulation blanket 28 covers the top of the greenhouse front wall 21. At night, the temperature in the greenhouse decreases, and the black PVC plastic water pipe 14 slowly and continuously releases heat through the hot water stored inside to supplement the temperature of the greenhouse, so as to ensure that the organisms in the greenhouse can grow normally at night. At the same time, the temperature inside the greenhouse can be collected by the temperature sensor 18 and transmitted to the temperature display instrument 16 through the signal line 17. The temperature display instrument 16 converts the signal into data information for easy observation of the temperature inside the greenhouse by the user.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
