[0030] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0031] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0033] Reference Figures 1-6 For the first embodiment of the present application, a sunlight greenhouse heat preservation wall is provided, which comprises a main body layer 1, a heat preservation layer 2, a heat collecting and distributing circulating water pipe 3, a supporting member 4 and a heat collecting and distributing layer 5, the heat preservation layer 2 and the supporting member 4 are respectively arranged on both sides of the main body layer 1, the heat collecting and distributing circulating water pipe 3 is arranged on the supporting member 4, the heat collecting and distributing layer 5 is arranged on the heat collecting and distributing circulating water pipe 3, the heat collecting and distributing layer 5 and the main body layer 1 form a heat collecting and distributing cavity 6, and the heat collecting and distributing circulating water pipe 3 is located in the heat collecting and distributing cavity 6.

[0034] In this embodiment, the main layer 1 ensures that the wall has sufficient strength, and the heat preservation layer 2 is laid on one side of the main layer 1 to effectively prevent the heat in the greenhouse from dissipating outward. The support 4 is installed on the other side of the main layer 1, which can be a metal bracket structure, and the heat collecting and distributing circulating water pipe 3 is stably erected on the support 4 so that it is not in contact with the main layer 1 and is in an overhead state. The heat collecting and distributing layer 5 is laid on the heat collecting and distributing circulating water pipe 3, which can be made of aluminum foil, PE cloth, black and white film, and other dark and flexible heat collecting materials. The heat collecting and distributing cavity 6 is formed between the heat collecting and distributing layer 5 and the main layer 1, and the heat collecting and distributing circulating water pipe 3 is located in the heat collecting and distributing cavity 6.

[0035] During the day, when the sunlight is sufficient, the sunlight shines on the heat collecting and distributing layer 5, which quickly absorbs heat and conducts it to the water in the heat collecting and distributing circulating water pipe 3. A temperature sensor can be installed, and when the temperature sensor detects that the temperature exceeds the set heat collecting temperature, the control system starts the circulation, causing the water in the heat collecting and distributing circulating water pipe 3 to begin circulating and storing heat, achieving the function of heat storage.

[0036] At night or when the temperature is lower, the temperature in the greenhouse decreases, and when the temperature sensor detects that the temperature is lower than the set heat dissipation temperature, the circulation is started again, causing the hot water in the heat collecting and distributing circulating water pipe 3 to circulate. The hot water transfers heat to the heat collecting and distributing layer 5, which in turn dissipates heat to the greenhouse, raising the temperature of the greenhouse and providing a suitable growing environment for warm-loving crops.

[0037] The support 4 makes the heat collecting and distributing circulating water pipe 3 overhead in the heat collecting and distributing cavity 6, not in contact with the main layer 1, increasing the contact area between the heat collecting and distributing circulating water pipe 3 and the air in the heat collecting and distributing cavity 6, and improving the heat exchange efficiency.

[0038] Further, the heat collecting and distributing circulating water pipe 3 is in a whole snake shape.

[0039] In this embodiment, during the construction of the heat preservation wall of the sunlight greenhouse, the heat collecting and distributing circulating water pipe 3 is designed to be in a whole snake shape. Specifically, the heat collecting and distributing circulating water pipe 3 is laid on the support 4 in a curved and winding manner. This snake-shaped design allows more length of the heat collecting and distributing circulating water pipe 3 to be arranged in a limited space, improving the heat storage efficiency.

[0040] Further, the support 4 includes a support column 41, a support rod 42, and a pipe clamping unit 43, the support column 41 is provided on the main layer 1, the support rod 42 is provided on the support column 41 and is a plurality of, the pipe clamping unit 43 is provided on the support rod 42, and the pipe clamping unit 43 is used to clamp and fix the heat collecting and distributing circulating water pipe 3.

[0041] Further, the support 4 further comprises a core column 44, which is slidingly arranged on the support column 41, and the support column 41 and the core column 44 are both provided with a plurality of pin holes 7 for inserting a fixing pin 8, and the support column 41 and the core column 44 are both provided with the support rod 42.

[0042] Further, the pipe clamp unit 43 comprises a fixed pipe clamp 431 and a movable pipe clamp 432, the fixed pipe clamp 431 is arranged on the support rod 42, and the movable pipe clamp 432 is swingably arranged on the support rod 42, and the movable pipe clamp 432 is used for clamping the heat collecting and distributing circulating water pipe 3 together with the fixed pipe clamp 431 after swinging.

[0043] Further, the fixed pipe clamp 431 and the movable pipe clamp 432 are both provided with a receiving groove 9, and the receiving groove 9 is used for accommodating the heat collecting and distributing circulating water pipe 3 after the fixed pipe clamp 431 and the movable pipe clamp 432 are closed.

[0044] Further, the inner wall of the receiving groove 9 is provided with a support rib 10.

[0045] In this embodiment, the support column 41 is a hollow structure, which plays an important role in installation. The core column 44 is slidingly arranged in the support column 41. When installing the heat collecting and distributing circulating water pipe 3, the length of the core column 44 extending out of the support column 41 can be adjusted according to the height requirement of the heat collecting and distributing circulating water pipe 3. When adjusted to the appropriate position, the fixing pin 8 is inserted into the corresponding pin hole 7 on the support column 41 and the core column 44 at the same time, so as to firmly lock the core column 44 at a specific height.

[0046] The support column 41 and the core column 44 are both provided with a plurality of support rods 42. When installing the heat collecting and distributing circulating water pipe 3, the water pipe is first placed in the receiving groove 9 on the fixed pipe clamp 431. The fixed pipe clamp 431 is fixed on the support rod 42. Then, the movable pipe clamp 432 is swung to the appropriate position, so that the receiving groove 9 of the movable pipe clamp 432 corresponds to the receiving groove 9 of the fixed pipe clamp 431, and clamps the heat collecting and distributing circulating water pipe 3 together. Subsequently, the movable pipe clamp 432 and the fixed pipe clamp 431 can be tightly fixed together by using common fixing methods such as bolts. In this way, a plurality of fixing points are formed on the heat collecting and distributing circulating water pipe 3 by a plurality of pipe clamp units 43, so as to realize the stable erection of the heat collecting and distributing circulating water pipe 3.

[0047] In addition, the top end of the core column 44 is also provided with a clamping groove. When the heat collecting and distributing circulating water pipe 3 presents a curved corner, the clamping groove can play a supporting role, further improving the stability of the heat collecting and distributing circulating water pipe 3. The inner wall of the receiving groove 9 is provided with a support rib 10, which enables the heat collecting and distributing circulating water pipe 3 to be in full contact with the air when clamped between the fixed pipe clamp 431 and the movable pipe clamp 432, increases the contact area between the heat collecting and distributing circulating water pipe 3 and the air in the heat collecting and distributing cavity 6, and improves the heat exchange efficiency.

[0048] First, the design of the support column 41 and the adjustable core column 44 provides a flexible solution for the overhead installation of the heat collection and circulation water pipe 3. The height of the core column 44 can be adjusted according to actual needs, adapting to the installation requirements of different specifications of the heat collection and circulation water pipe 3, thus improving the versatility of the device. Second, multiple pipe clamp units 43 form multiple fixing points on the heat collection and circulation water pipe 3, ensuring the stable installation of the heat collection and circulation water pipe 3. Whether in daily use in the greenhouse or facing slight vibrations from the external environment, it ensures that the heat collection and circulation water pipe 3 will not easily shift or loosen, guaranteeing the reliability of the system. Furthermore, the slot at the top of the core column 44 can support the bends of the heat collection and circulation water pipe 3, effectively improving stability and reducing the risk of damage caused by uneven stress at the bends. Finally, the design of the support ribs 10 on the inner wall of the receiving groove 9 allows the heat collection and circulation water pipe 3 to fully contact the air, further improving heat exchange efficiency. During the heat collection and dissipation process, heat transfer can be carried out more efficiently, providing a stable temperature environment for the greenhouse and meeting the growth needs of warm-loving crops.

[0049] An integrated heat dissipation system includes a solar greenhouse insulation wall, and further includes a water distributor 11, a water storage unit 12, a circulation pump 13, and a valve 14. The water distributor 11 is located on the main body layer 1. Both ends of the heat dissipation circulation water pipe 3 are connected to the water distributor 11. The water storage unit 12 is installed on one side of the wall and has an outlet pipe 15 and a return pipe 16. Both the outlet pipe 15 and the return pipe 16 are connected to the water distributor 11. The circulation pump 13 and the valve 14 are both located on the outlet pipe 15.

[0050] Furthermore, it also includes an electric heating rod 17, which is disposed inside the water storage unit 12.

[0051] Furthermore, it also includes a heat storage circulating water pipe 18, which is used to be buried in the underground soil below the wall, and both ends of the heat storage circulating water pipe 18 are connected to the water distributor 11.

[0052] In this embodiment, the water storage unit 12 is arranged at one side of the greenhouse, and has a water outlet pipe 15 and a water return pipe 16, both of which are communicated with the water distributor 11, so that the water storage unit 12 and the heat collecting and distributing circulating water pipe 3 are in circulation communication. In normal conditions, when heat collecting or heat dissipating circulation is needed, the valve 14 is opened and the circulating pump 13 is started. The circulating pump 13 provides power for water circulation, so that the water circulates between the water storage unit 12, the water outlet pipe 15, the water distributor 11, the heat collecting and distributing circulating water pipe 3, and the water return pipe 16. The heat storage circulating water pipe 18 buried in the underground soil under the greenhouse is also communicated with the heat collecting and distributing circulating water pipe 3 through the water distributor 11. In heat collecting, the hot water in the heat collecting and distributing circulating water pipe 3 can flow into the heat storage circulating water pipe 18, and store heat into the underground soil.

[0053] At night or when the temperature is low, the temperature in the greenhouse begins to drop. When the temperature sensor detects that the temperature is lower than the heat dissipating temperature, the control system starts the circulating pump 13, so that the water in the heat storage circulating water pipe 18 begins to circulate. The hot water flows out from the underground soil, flows into the heat collecting and distributing circulating water pipe 3 through the water distributor 11, dissipates the heat brought by the heat storage circulating water pipe 18 into the greenhouse, and raises the temperature in the greenhouse, so as to provide a suitable growth environment for the warm crops.

[0054] When there is no sunlight for consecutive overcast days, the temperature in the greenhouse can be lowered. At this time, the electric heating rod 17 arranged in the water storage unit 12 is started. The electric heating rod 17 starts to work and heats the water in the water storage unit 12. The heated water flows into the water distributor 11 through the water outlet pipe 15 under the action of the circulating pump 13, and then enters the heat collecting and distributing circulating water pipe 3, so as to dissipate heat into the greenhouse, thereby serving as an auxiliary heating measure to ensure that the temperature in the greenhouse is stably within the range suitable for the growth of crops.

[0055] Firstly, the arrangement of the water storage unit 12, the circulating pump 13 and the valve 14 ensures that the water in the heat collecting and distributing circulating water pipe 3 circulates stably, and can be timely collected and dissipated according to the need, thereby improving the efficiency and reliability of temperature regulation. Secondly, the arrangement of the electric heating rod 17 provides an auxiliary heating measure for the greenhouse in special conditions such as consecutive overcast days, so as to ensure that the temperature in the greenhouse is not too low, and to provide a stable environment for the growth of crops, thereby reducing the adverse effects of weather factors on agricultural production.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
