Technical Field

[0001] The present invention belongs to the technical field of water heat storage, and in particular relates to a strong water heat storage system capable of delaying heat storage. Background Art

[0002] Winters in northern regions are cold, and heat storage measures are needed to raise the temperature in the greenhouse in order to produce over the winter. Water as a heat storage carrier has the characteristics of high specific heat capacity, which means that more thermal energy can be stored in a unit mass of water. This enables the water heat storage system to store and release energy more efficiently. This patent improves the growth environment of greenhouse crops by comprehensively utilizing the physical properties of water. In colder climates, the growing season of crops can be extended, increasing opportunities for crop rotation and diversified planting, significantly improving the microclimate conditions inside the greenhouse, reducing temperature differences, reducing the risk of plant cold damage, and improving crop growth quality and yield.

[0003] Water thermal storage can be divided into active water thermal storage with circulation and passive water thermal storage without circulation according to whether external power energy is needed to circulate water. The existing active water thermal storage technology requires water tanks to store water, which occupies a large area, requires external energy, is costly, and is difficult to install; the existing passive water thermal storage with power belt as the thermal storage body fully utilizes the area of ​​the north wall, but it has the problem of too fast heat storage and release. Excessive heat absorption during the day leads to too high temperature in the greenhouse, and too fast heat release at night leads to insufficient heat in the greenhouse during the colder period in the second half of the night. Summary of the invention

[0004] In view of the above shortcomings, the purpose of the present invention is to provide a strong water-heat storage system that can delay heat storage. The purpose of the present invention is to reduce the cost of water heat storage technology while being easy to install, delay the heat storage and release speed of the system, and adjust the heat storage and release speed according to actual needs. The heat storage speed can be delayed during the day and the heat release speed can also be delayed at night.

[0005] The technical solution adopted by the invention is: a strong belt water heat storage system that can delay heat storage. The technical key points are that it includes a strong belt, a thermal insulation curtain and a driving structure. The strong belt is installed on the rear wall of the solar greenhouse, and the thermal insulation curtain is installed on the outer surface of the strong belt. The thermal insulation curtain is controlled to be rolled up or lowered by the driving structure.

[0006] Preferably, the strong belt is of U-shaped structure and is filled with water, with its upper end sealed.

[0007] Preferably, a plurality of strength belts are placed side by side between the vertical frames of the rear wall of the assembled solar greenhouse and are transversely fixed by tie rods.

[0008] Preferably, the rear wall vertical frame is connected to the tie rod via a fixing buckle, the rear end of the fixing buckle is provided with a clamping buckle for fixing the rear wall vertical frame, and the front end of the fixing buckle is also provided with a protruding hollow U-shape for connecting with the tie rod.

[0009] Preferably, the empty portion after the hollow U-shaped part is inserted into the tie rod is filled with an insert block which is thick at the top and thin at the bottom.

[0010] Preferably, the bottom of the heat preservation curtain at the top of the greenhouse transverse frame is connected to a driving rod, and the driving rod is drivingly connected to the motor.

[0011] Preferably, magnets are installed on both sides of the thermal insulation curtain 1, and the magnets are attracted to magnets fixedly connected to the walls of the solar greenhouse.

[0012] Preferably, vertical insulation blankets are installed at the overlapping parts of the greenhouse rear wall and the two sides of the insulation curtain 1.

[0013] The beneficial effects of the present invention are: a strong belt water heat storage system that can delay heat storage, includes a strong belt 4, an insulation curtain 1 and a driving structure, multiple strong belts 4 are installed side by side on the back wall of the solar greenhouse, which are fixed by transverse tie rods 2, and the insulation curtain 1 is installed on the outer surface of the strong belt 4. The insulation curtain 1 is rolled up or lowered by the driving structure. It can slow down the speed of heat storage. Through the adjustable characteristics of the thermal insulation curtain, it can control the heat storage and release speed of the heat storage body, avoid excessive temperature fluctuations, keep the temperature inside the greenhouse within a range more suitable for crop growth, and avoid excessive heat absorption during the day; it can extend the effective heat release time. Originally, the heat release was too fast at night, resulting in no heat to release in the second half of the night. Now, through the adjustment of the thermal insulation curtain, the heat release time can be extended to ensure that a certain temperature can be maintained throughout the night; it can reduce costs, better meet the needs of farmers, and is suitable for promotion; it is quick to install, and the installation is simple and fast using the installation clips and assembled solar greenhouses, and can be installed when the greenhouse is built; it can improve the stability of the greenhouse environment. The stable temperature environment helps to reduce sudden temperature changes in the greenhouse, reduce the impact of thermal expansion and contraction on the greenhouse structure and equipment, and extend the service life of the greenhouse.

[0016] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following is a brief description of the present invention in conjunction with the attached Figure 1-Figure 3 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0017] The passive water heat storage system of this embodiment includes a strong belt 4, an insulation curtain 1 and a driving structure. The strong belt 4 is installed on the back wall of the solar greenhouse, and the insulation curtain 1 is installed on the outer surface of the strong belt 4. The insulation curtain 1 is rolled up or lowered by the driving structure.

[0018] In this embodiment, a strong belt 4 is installed on the rear wall of the solar greenhouse. Multiple strong belts 4 are placed side by side between the vertical frames 5 of the rear wall of the assembled solar greenhouse and are fixed horizontally by tie rods 2. The strong belt 4 is a U-shaped structure and is filled with water inside, and its upper end is sealed. Multiple horizontally arranged tie rods 2 are fixedly connected with the vertically arranged rear wall vertical frames 5 by fixed buckles 3, and each strong belt 4 is assembled together, and the connected tie rods 2 are located on the surface of the strong belt 4. The fixed buckle 3 of this embodiment is U-shaped, and its rear end is a clamping buckle 3-1 for fixing the rear wall vertical frame 5. The rear wall vertical frame 5 is stuck in the fixed buckle 3-1, and the two sides are fixed by 3 nails. There is also a protruding hollow U-shaped 3-2 at the front end of the fixed buckle 3, and the tie rod 2 is inserted into the hollow U-shaped 3-2. The empty part of the hollow U-shaped 3-2 is filled and clamped by a thick upper and thin lower plug block to fix the tie rod 2. In this embodiment, the size of the fixed buckle connected at the top is longer than the fixed buckle below. In this embodiment, the heat preservation curtain 1 is supported by the fixing buckles 3 and the tie rods 2 , thereby reducing the friction between the fixing buckles 3 and the strong belts 4 .

[0019] The upper part of the thermal insulation curtain 1 of this embodiment is fixed to the greenhouse horizontal frame 6 by steel sheets 7 and nails 8, and the thermal insulation curtain material is a thermal insulation quilt. In order to achieve a more sealed state, magnets are installed on both sides of the thermal insulation curtain 1, and the magnets are installed vertically along the two sides of the thermal insulation curtain 1. At the same time, two vertical thermal insulation quilts are installed at the overlapped parts of the rear wall and the two sides of the thermal insulation curtain 1. The thermal insulation quilts are fixed with nails, and magnets are also installed on the thermal insulation quilt on the rear wall. When the thermal insulation curtain 1 is rolled up, the magnets on both sides will be attracted by the magnets fixed on the rear wall, and the strong belt 4 will be surrounded by the inside of the thermal insulation curtain 1 to reduce heat loss. In order to prevent the existence of a gap between the thermal insulation quilts and the thermal insulation curtains on both sides, the connection between the two is connected by a magnetic strip.

[0020] The thermal insulation curtain 1 of this embodiment is driven by a motor 10. A driving rod 11 is rolled up at the lower part of the thermal insulation curtain 1. The driving rod 11 is transmission-connected to the motor 10 arranged on one side thereof. The lower part of the motor 10 is fixed to the ground by a telescopic rod 9. The telescopic rod 9 is used to adjust the height of the motor 10.

[0021] The operation method of this embodiment is as follows: When you do not want the strong belt 4 to absorb too much heat during the day, you can turn on the motor 10 to lower the thermal insulation curtain 1 to delay the strong belt 4 from absorbing heat and avoid absorbing too much heat to cause the temperature in the greenhouse to be too high.

[0022] When the insulation blanket outside the shed is closed at night in winter, the insulation curtain 1 can be closed at the same time. After the insulation blanket is closed, the sunlight cannot reach the high-power belt. In order to delay the heat release, the insulation curtain is lowered to cover the high-power belt. When it is cold in the second half of the night, the insulation curtain can be opened again. This can increase the thermal resistance and delay the release of heat from the high-power belt water storage, so that the high-power belt 4 can still release heat when it is cold in the second half of the night.

[0023] The principle of the passive water heat storage system in this embodiment is: The high specific heat capacity of water is used to store and adjust the temperature in the greenhouse. The black surface of the strong belt 4 fully absorbs the radiant heat. The heat preservation curtain 1 is added in front of the strong belt 4 to increase the thermal resistance, delay the heat storage and release time, and stabilize the temperature fluctuation in the greenhouse.

[0024] This insulation structure enhances temperature stability, slows down the rate of temperature rise during the day and the rate of heat release at night, makes the temperature in the greenhouse more stable, and reduces large temperature fluctuations; flexible regulation: the insulation curtain can adjust the area of ​​​​the lowering, and can flexibly adjust the rate of heat storage and release to slow down the rate of heat storage and release according to different weather conditions and crop needs; reduce the occurrence of diseases and insect pests, excessive temperature fluctuations can easily lead to a decrease in crop immunity and increase the incidence of diseases and insect pests, while a stable temperature environment can enhance the resistance of crops and reduce the harm of diseases and insect pests; promote crop growth and development, suitable and stable temperature conditions provide a good growth environment for crops, which is conducive to the normal progress of physiological processes such as photosynthesis and respiration, thereby promoting the growth and development of crops and increasing yield and quality; Improve energy utilization efficiency: slowing down the rate of heat storage and release means that the stored heat can be more fully utilized, reducing heat waste, improving energy utilization efficiency, and reducing operating costs.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
