[0029] In order to better explain the utility model, so as to facilitate understanding, the following will be combined with the accompanying drawings Figures 1-5 , the utility model is described in detail through specific embodiments. Wherein, the orientation of the "upper", "lower" and other orientation terms mentioned in this paper is with the Figure 1 Direction for reference.

[0030] Example 1:

[0031] Reference Figures 1-5The embodiment of the utility model provides a kind of intelligent temperature control vegetable and fruit greenhouse system, including heat preservation earth wall 1, greenhouse body 2, heat insulation roller shutter 3, temperature sensor 4 and controller 5, the surface of heat preservation earth wall 1 towards illumination is light-receiving surface A;Greenhouse body 2 is located on foundation and is towards the side of light-receiving surface A, greenhouse body 2 and heat preservation earth wall 1 form the growth space of vegetable and fruit;Heat insulation roller shutter 3 is fixedly connected on light-receiving surface A, heat insulation roller shutter 3 can be switched between the first state of all covering light-receiving surface A, the second state of partially covering light-receiving surface A and the third state of all exposing light-receiving surface A, to make heat preservation earth wall 1 can be switched between heat preservation state, heat release state and heat absorption state, the first state corresponds heat preservation state, the second state corresponds heat release state, and the third state corresponds heat absorption state;Temperature sensor 4 is arranged in growth space to detect the temperature of growth space;Controller 5 is connected with temperature sensor 4, and is connected with heat insulation roller shutter 3, to control heat insulation roller shutter 3 switches to heat preservation state or heat release state.

[0032] In the embodiment, after light-receiving surface A of heat preservation earth wall 1 receives sunlight, heat radiation makes the temperature of heat preservation earth wall 1 rise, and then stores certain heat.

[0033] During the day, heat insulation roller shutter 3 can be switched to the third state, so that heat preservation earth wall 1 can quickly absorb heat and rise in temperature, and at night, heat insulation roller shutter 3 can be switched to the second state, so that the stored heat of heat preservation earth wall 1 is gradually released into the growth space of vegetable and fruit, to ensure that it has a constant temperature range, avoid freezing injury of vegetable and fruit, and improve the growth effect of vegetable and fruit.

[0034] Moreover, temperature sensor 4 can detect the temperature inside the greenhouse in real time, and feed back temperature information to heat insulation roller shutter 3, and then regulate and control the area of heat insulation roller shutter 3 covering light-receiving surface A through controller 5, so that heat preservation earth wall 1 can release heat at a suitable heat release rate, and then establish feedback control of the temperature inside the greenhouse, to help ensure that the temperature range in the greenhouse is constant.

[0035] Compared with the prior art, the utility model adds heat preservation roller shutter for regulating and controlling the heat release capacity of heat preservation earth wall 1, so that the heat release intensity of heat preservation earth wall 1 can be flexibly adjusted, to help maintain the temperature in the greenhouse and improve the growth effect of fruit and vegetable.

[0036] Specifically, the light-receiving surface A faces the light and can receive sunlight to increase the temperature of the earth wall through thermal radiation. The first state of the thermal insulation roller shutter 3 covers the light-receiving surface A to reduce heat loss of the thermal insulation earth wall 1. The second state partially covers the light-receiving surface A to allow the thermal insulation earth wall 1 to release heat to the growth space. The third state is a heat absorption state that maximizes the reception of sunlight to increase the temperature of the earth wall.

[0037] During the day, the thermal insulation roller shutter 3 switches to the third state, and the thermal insulation earth wall 1 quickly absorbs heat and increases in temperature, storing heat. At night, the thermal insulation roller shutter 3 switches to the second state, and the thermal insulation earth wall 1 releases heat to the growth space, maintaining a constant temperature range to prevent vegetables and fruits from being frozen. The temperature sensor 4 monitors the temperature inside the greenhouse in real time and feeds back information to the controller 5. The controller 5 adjusts the area of the thermal insulation roller shutter 3 covering the light-receiving surface A according to the temperature information, thereby controlling the heat release rate of the thermal insulation earth wall 1 to ensure a constant temperature in the greenhouse.

[0038] The system adds the thermal insulation roller shutter 3 to regulate the heat release capacity of the thermal insulation earth wall 1, allowing the heat release intensity to be flexibly adjusted, which is beneficial to maintaining a constant temperature in the greenhouse and improving the growth effect of vegetables and fruits. The thermal insulation earth wall 1 partially covered by the thermal insulation roller shutter 3 will not be completely exposed during heat release, which is beneficial to continuous heat release, reduces heat loss, and improves system reliability. Temperature feedback control is achieved through the temperature sensor 4 and the controller 5, which has high automation and reduces manual intervention, improving management efficiency.

[0039] In summary, the intelligent temperature control vegetable and fruit greenhouse system integrates components such as the thermal insulation earth wall 1, the thermal insulation roller shutter 3, the temperature sensor 4, and the controller 5 to achieve precise control and intelligent management of the temperature of the vegetable and fruit growth space. Compared with the prior art, the system has significant advantages in maintaining a constant temperature in the greenhouse, improving the growth effect of vegetables and fruits, and reducing heat loss.

[0040] Embodiment 2:

[0041] With reference to Figures 1-5 In addition to the above-mentioned technical solutions, the embodiments of the present application further have the following technical solutions:

[0042] The thermal insulation roller shutter 3 includes a roller shaft part 31 and a thermal insulation layer 32. The upper end of the thermal insulation layer 32 is fixedly connected to the roller shaft part 31, and the roller shaft part 31 is fixedly connected to the upper part of the light-receiving surface A, so that the lower end of the thermal insulation layer 32 can change the height position covering the light-receiving surface A.

[0043] In this embodiment, the reel part 31 is the driving and supporting structure of the thermal curtain 3, responsible for the rolling up and unrolling of the thermal layer 32. The reel part 31 is fixedly connected to the upper part of the light-receiving surface A of the thermal soil wall 1, ensuring that the thermal layer 32 can move smoothly up and down. The thermal layer 32 is the main part of the thermal curtain 3, with excellent thermal insulation performance, which can effectively reduce the exchange of heat between the inside and outside of the greenhouse. The thermal layer 32 can be made of lightweight and high-strength thermal insulation materials such as polystyrene foam, rock wool, etc., and can be filled with polystyrene foam or rock wool in the fabric cover. The upper end of the thermal layer 32 is fixedly connected to the reel part 31, and the rolling up and unrolling of the thermal layer 32 is realized through the driving device of the reel part 31, such as a motor.

[0044] The temperature sensor 4 monitors the temperature inside the greenhouse in real time and sends the data to the controller 5. The controller 5 determines the temperature condition inside the greenhouse according to the data provided by the temperature sensor 4 and issues instructions to control the driving device of the thermal curtain 3. The driving device receives the instructions of the controller 5 and drives the reel part 31 to roll up or unroll the thermal layer 32 to realize the switching of the state of the thermal curtain 3.

[0045] In summary, the thermal curtain 3 realizes precise control of the temperature inside the greenhouse through its flexible adjustment mechanism and excellent thermal insulation performance, providing a good environment for the growth of vegetables and fruits.

[0046] Embodiment 3:

[0047] With reference to Figures 1-5 In addition to the above-mentioned technical solutions, the embodiments of the present application further have the following technical solutions:

[0048] The light-receiving surface A is also provided with a heat dissipation arch B extending into the thermal soil wall 1, and the heat dissipation arch B is located at the lower part of the light-receiving surface A. The thermal curtain 3 can adjust the area covering the heat dissipation arch B to regulate the heat dissipation.

[0049] In this embodiment, the arched heat dissipation arch B helps to optimize air flow and heat transfer. As a heat release channel, the heat dissipation arch B can allow the heat stored in the thermal soil wall 1 to be released into the greenhouse through natural convection when needed. By adjusting the opening size of the heat dissipation arch B, i.e. the area covered by the thermal curtain 3, the release rate of heat can be controlled, and the temperature inside the greenhouse can be fine-tuned.

[0050] The thermal insulation roller shutter 3 not only covers the entire light-receiving surface A to regulate light and heat preservation, but also partially covers the heat dissipation arch B to regulate the amount of heat dissipation. When the temperature inside the greenhouse is too high, the controller 5 can instruct the thermal insulation roller shutter 3 to increase the area covering the heat dissipation arch B, allowing the amount of heat released into the greenhouse through the heat dissipation arch B to be reduced, thereby reducing the temperature. Conversely, when the temperature inside the greenhouse is too low, the thermal insulation roller shutter 3 can reduce the area covering the heat dissipation arch B, increasing the release of heat to maintain a stable temperature inside the greenhouse.

[0051] The controller 5 determines the temperature condition inside the greenhouse based on the data provided by the temperature sensor 4 and automatically adjusts the area of the thermal insulation roller shutter 3 covering the heat dissipation arch B. This intelligent control method allows the temperature inside the greenhouse to be maintained within a constant range, providing the best environmental conditions for the growth of vegetables and fruits.

[0052] In summary, the cooperation between the heat dissipation arch B and the thermal insulation roller shutter 3 provides a more flexible and efficient temperature regulation method for the intelligent temperature control greenhouse system. This design not only optimizes the growth environment of vegetables and fruits, but also improves the overall performance and energy efficiency of the greenhouse system.

[0053] Embodiment 4:

[0054] With reference to Figures 1-5 In addition to the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0055] The heat preservation soil wall 1 forms a heat preservation cavity inside, and the heat preservation cavity is filled with a heat preservation medium 6; the heat preservation medium 6 is heat preservation particles, and the heat preservation particles are quartz sand.

[0056] In this embodiment, the particle size and shape of the quartz sand particles are screened and treated to ensure their filling density and heat absorption effect in the heat preservation cavity. The quartz sand heat preservation particles have a low thermal conductivity, which can effectively slow down the heat loss rate. During the day, when sunlight shines on the light-receiving surface A, the heat preservation soil wall 1 absorbs heat and stores it in the heat preservation medium 6 in the heat preservation cavity. At night or on cloudy days, the heat preservation medium 6 releases the stored heat to maintain the stability of the temperature inside the greenhouse. By adjusting the covering state of the thermal insulation roller shutter 3, the temperature inside the greenhouse can be further regulated to achieve intelligent temperature management.

[0057] Embodiment 5:

[0058] With reference to Figures 1-5 In addition to the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0059] The light-receiving surface A is a transparent multi-layer tempered glass surface to form a light-transmitting heat preservation layer of the heat preservation soil wall 1.

[0060] In this embodiment, the light-receiving surface A uses multi-layer tempered glass as the main material. Tempered glass has high strength, high light transmittance and good thermal stability, and is a high-quality material commonly used in greenhouse construction. The multi-layer design further enhances the heat preservation and insulation performance of the glass, reducing the loss of heat and the influence of external temperature fluctuations on the interior of the greenhouse.

[0061] The light-receiving surface A as the light-transmitting heat preservation layer of the heat preservation earth wall 1 not only ensures that sunlight can fully irradiate the interior of the heat preservation earth wall 1, but also slows down the loss of heat through the heat preservation effect of the multi-layer tempered glass. This design enables the heat preservation earth wall 1 to efficiently absorb and store heat from sunlight during the day and slowly release this heat at night, maintaining a constant temperature inside the greenhouse.

[0062] The multi-layer tempered glass surface has high light transmittance, ensuring that sunlight can fully irradiate the interior of the heat preservation earth wall 1 and the vegetable and fruit growing space, promoting photosynthesis and the growth of vegetables and fruits. The multi-layer design reduces heat conduction and convection, effectively slowing down the rate of heat loss. At the same time, the thermal stability of the tempered glass enables the light-receiving surface A to maintain good heat preservation effect even under extreme weather conditions. The multi-layer tempered glass design of the light-receiving surface A works in conjunction with components such as the heat insulation roller shutter 3, temperature sensor 4 and controller 5 in the intelligent temperature control system to jointly control the temperature inside the greenhouse.

[0063] Specifically, in this embodiment, a vertically extending U-shaped space can be dug in the soil layer, the one side opening of the U-shaped space is closed by tempered glass, and the top opening of the U-shaped space is closed by the soil layer. The position where the heat dissipation arch B is opened can be supported by a support frame, which is plate-shaped and can be made of copper to prevent the leakage of the heat preservation medium 6 in the heat preservation cavity while ensuring heat conduction capacity. The tempered glass is pre-set to have a plate-shaped structure matching the shape of the heat dissipation arch B, and the outer edge of the tempered glass is connected to the heat preservation earth wall 1 by a connecting member, such as an anchor rod 8.

The heat conducting framework 7 can effectively transfer heat, improve the uniformity of heating and heat dissipation of the heat preservation earth wall 1, ensure that each part of the heat preservation earth wall 1 has a relatively uniform temperature during heating and cooling, and improve the structural stability of the heat preservation earth wall 1. The heat conducting framework 7 can be made of copper plates arranged in a horizontal and vertical cross pattern. The greenhouse using the heat conducting framework 7 can more effectively maintain the stability of the internal temperature, thereby improving the heat preservation effect.

[0067] Embodiment 7:

[0068] With reference Figures 1-5 In addition to having all the technical solutions of the above-mentioned embodiments, the embodiments of the utility model further have the following technical solutions:

[0069] The heat preservation cavity is provided with a vertical partition wall C, which divides the heat preservation cavity into N heat preservation units, and the heat dissipation arch door B is N and is arranged one by one corresponding to the heat preservation cavity. The heat insulation roller shutter 3 is arranged as N corresponding to the heat preservation cavity. The temperature sensor 4 is arranged as N corresponding to the heat preservation cavity, and the controller 5 can individually control each heat insulation roller shutter 3 to switch state.

[0070] In this embodiment, each heat preservation unit can be regarded as a small temperature control environment, which is convenient for more precise regulation of local temperature. Each heat preservation unit is provided with independent heat dissipation arch door B, heat insulation roller shutter 3 and temperature sensor 4, realizing the partition control of temperature. This design not only improves the flexibility of temperature regulation, but also helps to optimize the growth environment of vegetables and fruits, and meets the different needs of different types of vegetables and fruits for temperature. There are N heat dissipation arch doors B in the system, which correspond one by one to the N heat preservation units. As a heat release channel, the heat dissipation arch door B can allow the heat in the heat preservation unit to be released to the inside of the greenhouse in the form of natural convection when needed, realizing the fine adjustment of temperature. There are also N heat insulation roller shutters 3, which correspond one by one to the heat preservation units. The heat insulation roller shutter 3 can adjust the area covering the heat dissipation arch door B, so as to control the heat release rate. Under the instruction of the intelligent controller 5, the heat insulation roller shutter 3 can quickly switch state, respond to the data change of the temperature sensor 4, and realize precise control of temperature.

[0071] The heat preservation cavity is divided into multiple heat preservation units by the vertical partition wall C, and is equipped with independent heat dissipation arch door B, heat insulation roller shutter 3 and temperature sensor 4, and the system realizes the partition control of temperature. This design improves the flexibility of temperature regulation and helps to optimize the growth environment of vegetables and fruits.

[0072] The intelligent controller 5 can quickly adjust the state of the heat insulation roller shutter 3 according to the data of the temperature sensor 4, realizing precise control of temperature. This high efficiency reduces energy consumption and improves the use reliability of the system.
