Description

Technical Field

[0001] The invention relates to the technical field of cold-proof and heat-insulating covers, in particular to an intelligent cold-proof and heat-insulating cover for grapes without soil burial. Background Art

[0002] Most of my country's grape-growing areas belong to the temperate continental monsoon climate zone, with very cold and dry winters, little rain and more wind in spring, and hot and rainy summers and autumns. These characteristics lead to different ecological stresses in my country's grape production throughout the year, especially the severe cold in winter, which directly threatens the survival of grapes. Once frost damage occurs, the branches and roots of grapes will be damaged to varying degrees, manifested as late spring budding, uneven budding, weak growth of new shoots, poor differentiation of flower buds, low fruit setting rate, etc., which can seriously lead to plant death and crop failure.

[0003] The grape producing areas in my country that bury grapes for protection from the cold are mainly concentrated in Xinjiang, Gansu, Ningxia, Beijing, Jilin, Heilongjiang, Liaoning, Inner Mongolia, and parts of Shaanxi, Hebei, Shanxi and other places. It is generally believed that the absolute minimum temperature isotherm of -17℃ in winter is the dividing line between grapes that are buried in the soil for protection from the cold and grapes that are not buried in the soil for protection from the cold and overwinter in the open field. The dividing line between grapes that are covered and uncovered in winter in my country is roughly from Laizhou, Shandong to Jinan, to Xinxiang, Henan, Jincheng and Linyi, Shanxi, Dali, Jingyang, Qianxian and Baohong, Shaanxi, Tianshui, Gansu, and then south to Pingwu, Ma'erkang, Sichuan, and Lijiang, Yunnan. Grapes in areas south of this line can safely overwinter without covering; north of this line the absolute low temperature in winter is In areas between -21°C and -7°C in winter, grapes need to be buried in the soil and lightly covered to survive the winter. In areas north of this line where the absolute minimum temperature in winter is -21°C, grapes need to be buried in the soil and tightly covered in winter, otherwise frost damage will occur.

[0004] Grape buds are much more resistant to cold than their roots. For example, the buds of Eurasian species can tolerate about -12℃ more than the roots, and the buds of American species can tolerate about -15℃ more than the roots. After winter pruning, put soil pillows around the roots to prevent the vines from breaking when they are pressed down, and to increase the cold protection of the roots. Therefore, bundle the pressed vines into bundles, place them one by one at the roots, and cover them with straw or leaves. The thickness of the soil should be based on the thickness of the local winter frozen soil at -4℃ from the ground surface, that is, the thickness of the cold-proof soil. The thicker the -4℃ below the ground surface, the thicker the winter cold-proof soil for grapes. This cold-proof method is safe and reliable, and is generally used in Beijing's soil-burying cold-proof areas. If cold-resistant rootstock seedlings are used, the thickness of the soil should be reduced by about 1 / 3.

[0005] The traditional method of burying the soil to prevent cold mainly uses weeds, plant stems or woven materials such as straw mats to cover the grape vines and press the soil to keep them warm during the winter. It is time-consuming and labor-intensive, and is all disposable, which is a serious waste. In addition, it is not easy to cover tightly, the insulation effect is poor, and it is easy to damage the fruit branches. In the spring of the following year, a lot of manpower is also required for excavation, which affects the industrial development of the fruit planting industry, especially the development of the grape planting industry.

[0006] At present, the insulation facilities for covering grapes over the winter mainly use soft covering materials, which are generally covered directly on the grape vines. If necessary, it is necessary to cover the covering materials with soil, or drape the covering materials on a pre-built arch frame, and then cover the covering materials with soil. The operation is still relatively complicated and labor-intensive. In addition, this type of covering material is also troublesome and labor-intensive when releasing the grape vines in the spring of the following year.

[0007] CN200620129825.4 discloses a grape heat preservation cover, which is an arched frame, a retaining layer is laid on the outside of the frame, and then soil is covered on the retaining layer. First, the retaining layer and the frame used in the heat preservation cover are separate, which is inconvenient to construct. Second, after the retaining layer is covered, it is still necessary to cover the retaining layer with soil. In particular, the retaining layer is very unstable after being covered with soil, and will slide down with a slight vibration, thus greatly affecting the heat preservation effect. Third, the heat preservation cover has no heating function. When encountering extremely low temperatures, the temperature inside the cover will also be very low. It cannot play a role in keeping grapes warm, and the cold protection effect is poor. Summary of the invention

[0008] The purpose of the present invention is to provide an intelligent cold-proof and heat-insulating cover for grapes that does not require soil burial. The cover is easy to use, solves the problem of time-consuming and labor-intensive manual soil burial, reduces the damage to the roots and branches of grape branches caused by repeated soil burial every year, effectively prevents frostbite on the roots and branches, and ensures that the grape vines can safely survive the winter.

[0009] To achieve the above objectives, the present invention provides an intelligent cold-proof and heat-insulating cover for grapes without burying them in soil, comprising a cold-proof and heat-insulating cover, a heating device and a temperature control device are arranged on the inside of the cold-proof and heat-insulating cover, and an energy storage device is arranged on the outside of the cold-proof and heat-insulating cover.

[0012] Preferably, the heating device includes a low-pressure heating belt; the low-pressure heating belt is installed on the top and side of the inner side of the cold-proof and heat-insulating cover in a serpentine layout.

[0013] Preferably, the temperature control system includes an automatic switch and a temperature sensor; the automatic switch is arranged below the battery, and the temperature sensor is arranged below the low-pressure heating belt.

[0015] Preferably, a moisture-proof layer is provided inside the cover body of the cold-proof and heat-insulating cover; an anti-corrosion layer is provided outside the cover body of the cold-proof and heat-insulating cover; and a composite rock wool board is provided between the anti-corrosion layer and the moisture-proof layer.

[0016] Preferably, the solar panel and the low-voltage heating belt are electrically connected to the battery respectively; and the temperature sensor and the automatic switch are electrically connected.

[0017] Therefore, the present invention adopts the above-mentioned intelligent cold-proof and heat-insulating cover for grapes that does not need to be buried in the soil. When in use, the cold-proof and heat-insulating cover is directly covered on the pruned grape vines, which is easy to use and solves the problem of time-consuming and labor-intensive manual soil burying. When the temperature drops, the cold-proof and heat-insulating cover can automatically dissipate heat, increase the temperature inside the cold-proof and heat-insulating cover, and ensure that the grape vines can safely overwinter. The cold-proof and heat-insulating cover with a heating device does not need to be covered with soil, which reduces the damage to the roots and branches of the grape branches caused by repeated soil burial every year, effectively prevents frostbite of the roots and branches, and ensures that the grape vines can safely overwinter.

[0025] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0027] like Figure 1 As shown, the present invention provides an intelligent cold-proof and heat-insulating cover for grapes without burying them in the soil, including a cold-proof and heat-insulating cover 1, a heating device and a temperature control device are arranged on the inner side of the cold-proof and heat-insulating cover 1, and an energy storage device is arranged on the outer side of the cold-proof and heat-insulating cover 1. The shape of the cold-proof and heat-insulating cover 1 is a hollow quadrangular pyramid, the front of which is a square with a length of 1.5m and a height of 1.5m, and the side is an isosceles trapezoid with an upper base of 0.4m, a lower base of 0.6m, and a waist length of 1.5m. The bottom of the cold-proof and heat-insulating cover 1 is open and buckled on the ground to form a closed cavity that can accommodate grape vines, creating a microclimate and a small ecological space for the grape vines to protect against the cold during the winter.

[0028] The four sides of the bottom of the cold-proof and heat-insulating cover 1 are provided with plug plates 6, which are arranged perpendicular to the horizontal plane. The plug plates 6 of the cold-proof and heat-insulating cover 1 can be inserted into the ground soil. If the cold-proof and heat-insulating cover 1 is simply placed on the ground, it may leak air due to uneven placement, or it may be overturned in windy weather due to unstable placement. Therefore, the purpose of designing the plug plates 6 at the bottom of the cold-proof and heat-insulating cover 1 is to ensure the sealing and stability of the cold-proof and heat-insulating cover 1.

[0029] like Figure 4As shown, an observation window 12 is provided at the lower side of the cold-proof and heat-insulating cover 1, and a heat-insulating glass 7 is inlaid on the observation window 12. The technician can observe the survival status of the grapevine in the cold-proof and heat-insulating cover 1 at any time through the observation window 12. The setting of the heat-insulating glass 7 can also seal the cold-proof and heat-insulating cover 1 to ensure that its heat-insulating performance does not decrease. The upper part of the observation window 12 is connected to the cold-proof and heat-insulating cover 1 through a hinge, and a handle 13 is provided below the observation window 12. The technician can open the observation window 12 upward and outward through the handle 13, which is convenient for the technician to open the observation window 12 at any time to observe the growth status of the grapevine at close range and prune the grape branches. At the same time, it is also convenient for the technician to repair and replace the parts of the cold-proof and heat-insulating cover, avoiding the problem of frostbite of the grapevine caused by removing the cold-proof and heat-insulating cover 1.

[0030] like Figure 2 As shown, the cover body of the cold-proof and heat-insulating cover 1 uses a heat-insulating layer structure, and a moisture-proof layer 10 is arranged on the inner side of the cold-proof and heat-insulating cover 1. The respiration and transpiration of the grapevine will produce water vapor. Because the cold-proof and heat-insulating cover 1 is airtight, the water vapor will adhere to the inner wall of the cold-proof and heat-insulating cover 1. The moisture-proof layer 10 can prevent the water vapor from damaging the cold-proof and heat-insulating cover 1 due to moisture. An anti-corrosion layer 8 is arranged on the outer side of the cover body of the cold-proof and heat-insulating cover 1 to prevent the substances in the external environment from corroding and damaging the cold-proof and heat-insulating cover 1, so the moisture-proof layer 10 and the anti-corrosion layer 8 can extend the service life of the cold-proof and heat-insulating cover 1. A composite rock wool board 9 is arranged between the anti-corrosion layer 8 and the moisture-proof layer 10. The composite rock wool board 9 is a good heat-insulating material, which can enhance the warmth-keeping performance of the cold-proof and heat-insulating cover 1 and create a better wintering environment for the grapevine.

[0031] The energy storage device includes a solar panel 2 and a battery 3; the solar panel 2 is respectively arranged on the front side, the rear side, the left side and the upper side of the cold-proof and heat-insulating cover 1; the battery 3 is arranged on the right side of the cold-proof and heat-insulating cover 1. In view of the environment of Ningxia, Xinjiang and Gansu, there is sufficient solar energy. In order to save resources and protect the environment, the solar panel 2 can be used to collect solar energy for power generation and heating. The solar panel 2 on the top of the cold-proof and heat-insulating cover 1 can receive solar energy all day long, and the solar panel 2 on the wide side can store solar energy according to the different directions of the sun at different times. When the temperature is high during the day, the cold-proof and heat-insulating cover 1 does not need to adjust the temperature. The battery 3 is electrically connected to the solar panel 2, and the collected solar energy is stored in the battery 3. The battery adopts a 48-volt 12A lead-acid battery, which can store about 0.5 degrees of electricity and can be fully used for the heating device of the cold-proof and heat-insulating cover 1.

[0032] like Figure 3As shown, the heating device includes a low-pressure heating belt 11; the low-pressure heating belt 11 is installed on the top and side of the inner side of the cold-proof and heat-insulating cover 1, and is arranged in a serpentine shape. The low-pressure heating belt 11 can convert electrical energy into thermal energy to generate heat, heat the inside of the cold-proof and heat-insulating cover 1, and provide a suitable wintering temperature for the grapevine. The low-pressure heating belt 11 is coiled and fixed inside the cold-proof and heat-insulating cover 1, and the number of coiling and fixing turns is determined according to the size of the low-pressure heating belt 11. The low-pressure heating belt 11 is electrically connected to the battery 3, and the electricity stored in the battery 3 is transmitted to the low-pressure heating belt 11 for generating heat.

[0033] like Figure 2 As shown, the temperature control system includes an automatic switch 5 arranged on the left side below the battery 3 and a temperature sensor 4 arranged below the low-pressure heating belt 11. The temperature sensor 4 is electrically connected to the automatic switch 5, and the automatic switch 5 is also electrically connected to the low-pressure heating belt 11. The temperature of the temperature sensor 4 can be set to the opening temperature and the closing temperature as needed. When the temperature is lower than the opening temperature, the automatic switch 5 is turned on to turn on the low-pressure heating belt 11 to heat the inside of the cold-proof and heat-insulating cover 1, and when the temperature is higher than the closing temperature, the automatic switch 5 is closed to stop heating. For example, the opening temperature is set to -15°C and the closing temperature is set to -10°C. When the temperature is higher than -10°C during the day, the temperature sensor 4 and the low-pressure heating belt 11 do not work. When the temperature is lower than -15°C at night, the temperature sensor 4 sends a signal, the automatic switch 5 receives the signal, and the automatic heating belt 11 is started. The automatic heating belt 11 heats the inside of the cold-proof and heat-insulating cover 1. When the temperature inside the cold-proof and heat-insulating cover 1 is higher than -10°C, the temperature sensor 4 receives the signal and transmits it to the automatic switch 5, and the automatic switch 5 controls the low-pressure heating belt 11 to close.

[0034] When the present invention is used, with the arrival of winter, the temperature in Ningxia, Xinjiang, Gansu and other places decreases, and the grapevines are afraid of cold. If they cannot keep warm, the grapevines will freeze to death or be dried out by wind, affecting the harvest of the next year. Therefore, when winter comes, the technicians trim the grapevines to a suitable height, and then put on the cold-proof and heat-insulating cover 1. The bottom of the cold-proof and heat-insulating cover 1 is provided with a plug plate 6, and the plug plate 6 is inserted into the soil around the grapevine to seal and prevent the cold-proof and heat-insulating cover 1 from leaking air. The temperature sensor 4 in the cold-proof and heat-insulating cover 1 monitors the temperature inside the cold-proof and heat-insulating cover 1 at any time. When it is set to be lower than -15°C, it triggers a signal and transmits the signal to the automatic switch 5 to control the opening and closing of the automatic switch 5. The automatic switch 5 is electrically connected to the low-voltage heating belt 11.

[0035] During the day, the temperature is high, higher than -15°C, the temperature sensor 4 does not send a signal, the automatic switch 5 is turned off, and the low-pressure heating belt 11 in the cold-proof and heat-insulating cover 1 is turned off. Therefore, during the day, the solar panel 2 outside the cold-proof and heat-insulating cover 1 receives solar energy and converts the solar energy into electrical energy and stores it in the battery 3 on the narrow side of the cold-proof and heat-insulating cover 1. The battery 3 is electrically connected to the low-pressure heating belt 11. At night, when the temperature in the cold-proof and heat-insulating cover 1 decreases, when the temperature is lower than -15°C, the temperature sensor 4 receives a signal and transmits it to the automatic switch 5, turning on the low-pressure heating belt 11 to heat the air in the cold-proof and heat-insulating cover 1. When the internal temperature is higher than -10°C, the temperature sensor 4 transmits a signal to the automatic switch 5 to turn off the low-pressure heating belt 11. This allows the cold-proof and heat-insulating cover 1 to maintain a constant temperature suitable for the grapevines to overwinter.

[0036] The technicians can observe the status of the grapevine and the status of each component through the observation window 12 on the cold-proof and heat-insulating cover 1, so as to save the grapevine and repair each device in time.

[0037] The grape varieties applicable to the present invention include but are not limited to wine grapes, table grapes, etc., and the grape tree rack types applicable to the present invention include but are not limited to V-shaped racks, bird racks, etc.

[0038] Therefore, the present invention adopts the above-mentioned intelligent cold-proof and heat-insulating cover for grapes that does not need to be buried in the soil. When in use, the cold-proof and heat-insulating cover is directly covered on the grape vines after construction. It is easy to use and solves the problem of time-consuming and labor-intensive manual soil burial. When the temperature drops, the cold-proof and heat-insulating cover can automatically dissipate heat, increase the temperature inside the cold-proof and heat-insulating cover, and ensure that the grape vines can safely overwinter. The cold-proof and heat-insulating cover with a heating device does not need to be covered with soil, which reduces the damage to the roots and branches of the grape branches caused by repeated soil burial every year, effectively prevents frostbite of the roots and branches, and ensures that the grape vines can safely overwinter.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
