Technical Field
[0001] The utility model relates to the technical field of greenhouse cultivation, in particular to a temperature control device for promoting off-season cultivation of fruit trees. Background Art
[0002] Off-season dormancy technology for fruit trees involves artificially inducing fruit trees to enter or exit dormancy during unnatural seasons, allowing them to bloom and bear fruit earlier. The promotion of this technology can help fruit trees effectively respond to climate change and shifts in market demand, improving their production efficiency and economic benefits. The emergence of dormancy in fruit trees typically requires a certain low temperature requirement, or cooling capacity, to successfully transition through their natural dormancy period and enter a new growth cycle.
[0003] Off-season cultivation of fruit trees is usually carried out under facility conditions. In production, refrigeration equipment such as air energy is often used to create a low-temperature environment to meet the natural dormancy of fruit trees. Fruit trees need to enter a dormant state when both the air and soil temperatures are below 7.2°C. Although refrigeration equipment such as air energy can effectively reduce the temperature of the air and surface soil, the cooling effect on deep soil is limited. This makes the ambient temperature distribution where the fruit tree roots are located uneven and the required cooling capacity is insufficient, thus affecting the quality and efficiency of the fruit. In addition, the temperature, humidity and application of gas fertilizers in the greenhouse during the fruit tree growth period are currently regulated separately, which is cumbersome and inconvenient to control.
[0004] In view of this, a temperature control device was designed to promote off-season cultivation of fruit trees, which significantly improved the cooling performance of air energy and other gas refrigeration equipment in dealing with air and soil temperatures. It can also mix the temperature, humidity and gas fertilizer required by fruit trees and then transport them to the greenhouse, greatly improving the convenience of operation.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described clearly and completely below in conjunction with specific embodiments.
[0030] like Figure 1 and Figure 3 A temperature control device for promoting off-season cultivation of fruit trees is shown, comprising a solar greenhouse and a refrigeration device disposed within the greenhouse. The greenhouse comprises a rear wall 1, a west wall 2, an east wall 3, and a plastic film, wherein the plastic film covers the tops of the rear wall 1, the west wall 2, and the east wall 3.
[0031] The west wall 2 and the east wall 3 are hollow walls, and an intake fan 12 is provided on the inner wall of the west wall 2, and / or an exhaust fan 20 is provided on the inner wall of the east wall 3; one or both of the intake fan 12 and the exhaust fan 20 can be provided, and when both are provided, the working power of the two fans is the same.
[0032] Multiple cooling pipes 13 are connected between the west wall 2 and the east wall 3. The cooling pipes 13 are laid in the soil. The cooling pipes 13 are made of a material with good heat exchange performance, preferably stainless steel or plastic. The cooling pipes 13 are laid 40 cm below the soil.
[0033] like Figure 2 and Figure 3 As shown, as a further optimization, the refrigeration equipment includes a refrigerator 19, and the cold air outlet of the refrigerator 19 is respectively connected to the first ventilation duct 6 and the second ventilation duct 7 through a three-way joint. The air outlet of the first ventilation duct 6 is located inside the greenhouse, and the air outlet of the second ventilation duct 7 is connected to the interior of the west wall 2; the interior of the west wall 2 is connected to the interior of the greenhouse through the third ventilation duct 8; the side wall of the west wall 2 is provided with a gas fertilizer application pipeline 17 and a humidity adjustment pipeline 18 connected to the interior thereof; the first ventilation duct 6 is provided with a first valve 9, the second ventilation duct 7 is provided with a second valve 10, and the third ventilation duct 8 is provided with a third valve 11.
[0034] The gas fertilizer application pipeline 17 and the humidity control pipeline 18 are arranged on the outer wall of the west wall 2, and the second ventilation duct 7 is connected to the inner wall of the west wall 2. The pipe openings of the gas fertilizer application pipeline 17 and the humidity control pipeline 18 are arranged directly opposite the pipe opening of the second ventilation duct 7. As a further optimization, an atomizing nozzle is provided at the pipe opening of the humidity control pipeline 18, and a drain pipe is provided at the bottom of the side wall of the west wall 2 for draining condensed water.
[0035] When cultivating fruit trees off-season, the second valve 10 and the third valve 11 are closed, the first valve 9 is opened, and the refrigerator 19 is used for cooling, and the cold air is quickly distributed to the greenhouse through the first ventilation duct 6 and the ventilation pipe 4. When the temperature in the greenhouse is lower than the soil temperature, the suction fan 12 is started to buffer the cold air in the greenhouse through the cavity of the west wall 2 and then transport it to the cooling pipe 13 buried under the soil. When the cold air flows in the cooling pipe 13, it exchanges heat with the soil, thereby lowering the soil temperature. Then, the cold air with a slightly risen temperature enters the buffer in the east wall 3 and is discharged to the room through the exhaust fan 20 on the east wall 3, thereby effectively lowering the soil temperature and significantly improving the cooling performance of air energy and other gas refrigeration equipment in dealing with air and soil temperatures.
[0036] When off-season cultivation is not being carried out, the west wall 2 can be used as a gas conditioning chamber to mix the cold air introduced by the second ventilation duct 7, the CO2 and other gas fertilizers introduced by the gas application pipeline 17, and the moisture or spray introduced by the humidity control pipeline 18, and then transport them into the greenhouse through the third ventilation duct 8, greatly improving the convenience of operation. When the west wall 2 is used as a gas conditioning chamber, the first valve 9 is closed, the second valve 10 and the third valve 11 are opened, and the cold air discharged by the refrigerator 19 enters the west wall 2 through the second ventilation duct 7, and then offsets the CO2 and other gas fertilizers introduced by the gas application pipeline 17, and the moisture or spray introduced by the humidity control pipeline 18, achieving sufficient mixing, and then quickly distributed to the greenhouse through the third ventilation duct 8 and the ventilation pipe 4, greatly improving the convenience of operation.
[0037] like Figure 1-Figure 3 As shown, the first ventilation duct 6 and the third ventilation duct 8 are both arranged horizontally along the length of the greenhouse, and multiple air outlets are evenly arranged on the first ventilation duct 6 and the third ventilation duct 8. The first ventilation duct 6 and the third ventilation duct 8 are both arranged horizontally along the length of the greenhouse, and multiple ventilation pipes 4 are evenly arranged between them along the length of the rear wall 1. The ventilation pipes 4 are arranged vertically, and their upper and lower ends are respectively connected to the first ventilation duct 6 and the third ventilation duct 8. Multiple ventilation holes 5 are evenly opened on the side walls of the ventilation pipes 4.
[0038] like Figure 4As shown, as a further optimization, an isolation box 14 is provided at the lower part of the west wall 2, the cooling pipe 13 is connected to the isolation box 14, an air inlet pipe 15 is provided in the middle part above the isolation box 14, and a fourth valve 16 is provided on the air inlet pipe 15; the first ventilation pipe 6, the second ventilation pipe 7 and the third ventilation pipe 8 are connected to the west wall 2 at the top of the isolation box 14. The isolation box 14 is a detachable box body provided at the bottom of the west wall 2 (refer to Figure 5 ), or, a partition is horizontally provided above the cooling pipe 13 at the lower part of the west wall 2, and the isolation box 14 is formed below the partition (refer to Figure 6 By providing the isolation box 14, the air inlet pipe 15, and the fourth valve 16, the cavity of the west wall 2 is used as a gas adjustment chamber. After the temperature, humidity, and gas fertilizer are mixed, the mixed gas can be prevented from entering the cooling pipe 13. At the same time, condensed water can also be prevented from entering the cooling pipe 13, ensuring that the mixed gas can quickly diffuse into the interior of the greenhouse through the ventilation pipe 4.
[0039] As a further optimization, the intake fan 12 and the exhaust fan 20 are hinged with automatic doors, which can be opened and closed by a motor, so as to prevent the mixed gas or the gas in the greenhouse from passing back and forth through the installation frame of the intake fan 12 and the exhaust fan 20. When the cavity of the west wall 2 is used as a gas regulating room, the gas in the greenhouse is prevented from entering the west wall 2 through the installation frame, which affects the mixing of the gas in the gas regulating room. At the same time, it also prevents the mixed gas from entering the greenhouse through the installation frame, which affects the transportation and distribution of the mixed gas into the greenhouse.
[0040] As a further optimization, the first valve 9, the second valve 10, the third valve 11 and the fourth valve 16 are all solenoid valves to achieve automatic control of the entire temperature control device.
