Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, and more specifically, to a heat-collecting cavity and a temperature-regulating and moisture-retaining greenhouse. Background Technology

[0002] Greenhouses generally consist of two side walls, a back wall, a supporting frame, and covering material on the supporting frame. They are important agricultural facilities in northern regions. The covering material on the supporting frame is often made of transparent plastic film, which mainly provides a suitable temperature and humidity environment for crops in autumn and winter, thereby increasing crop yields and enabling northern regions to obtain fresh fruits and vegetables in autumn and winter.

[0003] At night or during severe cold weather, when the temperature inside the greenhouse is low, heating furnaces or electric heaters are often used to raise the temperature. During the day, when the temperature inside the greenhouse is high, ventilation is often needed to prevent crops from wilting and drying out. However, daytime ventilation causes the heat collected inside the greenhouse to be lost, and using heating equipment at night or during severe cold weather consumes a lot of energy. Therefore, there is an urgent need for a heat-collecting cavity that can simultaneously regulate the temperature and humidity inside the greenhouse, as well as a temperature-regulating and humidity-retaining greenhouse with multiple heat storage modes and the ability to raise the temperature inside the greenhouse when it is low, saving energy. These are technical problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0025] This application provides a heat-collecting cavity and a temperature-regulating and humidity-retaining greenhouse to solve the technical problems of existing greenhouses, such as the inconvenience of simultaneously regulating the temperature and humidity inside the greenhouse, the single heat storage mode, and the high energy consumption for raising the temperature inside the greenhouse when the temperature is low. To this end, this application provides the following specific embodiments.

[0026] Example 1 This embodiment provides a heat collection cavity, as shown in the reference. Figures 1 to 12 It includes a cavity body, wherein the heat collection cavity is configured to have multiple cavity bodies, and the cavity bodies are inclinedly arranged in the upper space of the greenhouse, as shown in the reference. Figure 2The cavity body is connected to the temperature-regulating water wall 2, and heat-collecting water circulates between the cavity body and the temperature-regulating water wall 2. The cavity body absorbs heat from the upper space of the greenhouse and stores it in the heat-collecting water. When the temperature inside the greenhouse is high during the day, the cavity body absorbs the hot air from the upper space of the greenhouse, causing the cold air in the lower space of the greenhouse to circulate upward, thereby reducing the temperature inside the greenhouse. At night or when the temperature inside the greenhouse is low in cold weather, the heat-collecting water in the cavity body and the temperature-regulating water wall 2 releases heat to help raise the temperature inside the greenhouse. Raising the temperature inside the greenhouse when the temperature inside the greenhouse is low saves energy consumption.

[0027] The cavity body is configured as a closed cavity, with a second water supply pipe 5 and a second water return pipe 9 respectively installed at both ends. The cavity body is connected to the temperature regulating water wall 2 through the second water supply pipe 5 and the second water return pipe 9, and the heat collection water is circulated between the temperature regulating water wall 2 and the cavity body by a circulating water pump. The upper surface of the cavity body is evenly distributed with heat collection holes 3-3. The hot air in the upper space of the greenhouse is conducted to the heat collection water through the heat collection holes 3-3 and the thin-walled structure of the cavity body, which improves the heat exchange rate, the heat collection efficiency is higher, and the temperature regulation effect is more obvious.

[0028] Specifically, a polyethylene pipe is longitudinally arranged inside the cavity body. The two ends of the polyethylene pipe are connected to the second water supply pipe 5 and the second water return pipe 9, respectively. Multiple micro-nozzles are evenly distributed on the polyethylene pipe and are connected to the polyethylene pipe. The micro-nozzles spray the heat-collecting water from the second water supply pipe 5 into a mist, which can more effectively collect the heat in the upper space of the greenhouse. The mist of heat-collecting water sprayed by the micro-nozzles flows back to the temperature-regulating water wall 2 through the second water return pipe 9. The heat-collecting water is sprayed out from the micro-nozzles in a mist, collects the heat in the upper space of the greenhouse and flows to the heat-collecting cavity 3, thereby reducing the heat in the heat-collecting cavity 3, promoting air circulation between the heat-collecting cavity 3 and the upper space of the greenhouse, collecting the temperature of the inner space of the greenhouse and storing it in the heat-collecting water.

[0029] The heat collection cavity 3 includes multiple sets of cavity bodies arranged opposite to each other, as shown in the figure. Figure 3 The cavity body is configured as a thin-walled closed cavity. The cavity body is made of a material with high thermal conductivity, such as stainless steel or hard plastic. The surface of the cavity body is black. The cavity body is placed in the upper space of the greenhouse. The cavity body also absorbs heat from inside the greenhouse. The heat-collecting water sprayed from the micro-nozzle falls onto the cavity body and flows to the second return water pipe 9, continuing to absorb heat from the heat-collecting cavity. Finally, it flows back to the temperature-regulating water wall 2 along the second return water pipe 9.

[0030] An air suction pipe 7 is provided on the end face of the cavity body. The air suction pipe 7 is located on one side end face of the second water supply pipe 5, as shown in the figure. Figure 3 , Figure 4 and Figure 7 The air intake pipe 7 is connected to an air pump installed inside the greenhouse. The air pump is installed in the lower space of the greenhouse or on the ground. The air pump discharges hot air or mist from the cavity into the greenhouse, increasing the temperature and humidity of the lower space, which is beneficial to the growth of crops grown in the greenhouse.

[0031] Specifically, a valve 10 is installed on the second water supply pipe 5. Adjusting the opening or closing of the valve 10 allows the cavity body to be set to a water-containing or waterless state. When the temperature in the lower space of the greenhouse is low in the morning, the valve 10 is closed, and the heat collection cavity 3 is set to a waterless state. The air suction pipe 7 is connected to an air pump, which is located in the lower space of the greenhouse or placed on the ground. The air pump draws hot air from the upper space of the greenhouse to the lower space, raising the surface temperature of the crops grown in the greenhouse and promoting their growth.

[0032] When the temperature inside the greenhouse is high during the day, valve 10 is opened, and the heat collection cavity 3 is set to a water-filled state. The second water supply pipe 5 introduces the heat collection water into the micro-nozzle through a longitudinally arranged polyethylene pipe. The heat collection water is sprayed out in a mist form through the micro-nozzle. The mist-sprayed heat collection water can effectively collect the heat in the upper space of the greenhouse, thereby promoting air circulation in the greenhouse and reducing the temperature inside the greenhouse. The heat in the upper space of the greenhouse is stored in the heat collection water. The heat collection water flows back to the temperature regulating water wall 2 through the second return water pipe 9, thereby storing the heat in the upper space of the greenhouse in the temperature regulating water wall 2.

[0033] The cavity body is provided with a second water supply pipe 5 and a second water return pipe 9 at its end. The second water return pipe 9 is located below the heat collection cavity 3 to facilitate the return of heat collection water. The second water supply pipe 5 and the second water return pipe 9 are respectively connected to the temperature regulating water wall 2. The heat collection cavity 3 collects heat from the upper space of the greenhouse and stores it in the temperature regulating water wall 2. When the temperature inside the greenhouse is high during the day, it absorbs heat from the interior space of the greenhouse and stores it in the heat collection cavity 3 and the temperature regulating water wall 2.

[0034] The cavity body is supported on the arc-shaped support 4, the arc-shaped support 4 is fixed on the support rod, and the support rod is fixed on the ground; the arc-shaped support 4 is in contact with the lower surface of the cavity body, the tail end of the arc-shaped support 4 has an arc-shaped bend, and the cavity body is snapped onto the arc-shaped bend.

[0035] The cavity body includes a first cavity body 3-1 and a second cavity body 3-2; the first cavity body 3-1 is configured as a straight strip cavity, and the first cavity body 3-1 is arranged in a strip shape in the upper space of the greenhouse; the second cavity body 3-2 is configured as an arc-shaped strip cavity, and the second cavity body 3-2 is also arranged in a strip shape in the upper space of the greenhouse, and the first cavity body 3-1 and the second cavity body 3-2 are in relative positions so that the heat collection cavity 3 is placed in the top space of the greenhouse, which facilitates the collection of heat from the top of the greenhouse into the heat collection cavity 3.

[0036] The arc-shaped support 4 includes a first arc-shaped rod 4-1 and a second arc-shaped rod 4-2, as shown in the reference. Figure 8 The first arc-shaped rod 4-1 is in contact with the bottom surface of the first cavity body 3-1, and the first arc-shaped rod 4-1 is threaded or welded to the support rod; the second arc-shaped rod 4-2 is in contact with the bottom surface of the second cavity body 3-2, and the second arc-shaped rod 4-2 is threaded or welded to the support rod. The tail ends of the first arc-shaped rod 4-1 and the second arc-shaped rod 4-2 are provided with arc-shaped bends, and the arc-shaped bends are adapted to the arc-shaped rounded corners of the cavity body. The first cavity body 3-1 and the second cavity body 3-2 are both snapped onto the arc-shaped bends.

[0037] Example 2 This embodiment provides a temperature-regulating and humidity-retaining greenhouse, including a heat-collecting cavity as described in Embodiment 1, with reference to... Figures 1 to 12 It also includes a temperature-regulating water wall 2, which is arranged parallel to the rear wall on the back or serves as the rear wall on the back.

[0038] Specifically, the temperature-regulating water wall 2 includes multiple sets of adjacent temperature-regulating water wall units 2-1, as shown in the figure. Figure 10 The temperature-regulating water wall unit 2-1 is configured as a thin-walled hollow tube made of polypropylene plastic; the top of the temperature-regulating water wall 2 is provided with a hanging ear 2-4, which is hung on a hook, and the hook is set on the support frame 1, as shown in the figure. Figure 1 Compared to existing technologies that fold the heating water wall bag in half and clamp it with a crossbar, the temperature-regulating water wall of this application is easier to install, facilitates the entry and exit of heat collection water, and facilitates the formation of a water circulation system with the heat collection plate 6 and the heat collection cavity 3 for heat exchange.

[0039] The temperature-regulating water wall unit 2-1 includes multiple vertical column-shaped pipes that are closely connected to each other. The bottom of each vertical column-shaped pipe is also provided with a horizontal column-shaped pipe, which is connected to the multiple vertical column-shaped pipes.

[0040] Preferably, the temperature-regulating water wall unit 2-1 is internally equipped with an air pipe 8, as shown in the reference. Figure 11 and Figure 12 The air pipe 8 is connected to an air pump located in the upper space of the greenhouse. The air pump introduces hot air from the upper space of the greenhouse into the temperature-regulating water wall unit 2-1, heats the heat-collecting water in the temperature-regulating water wall unit 2-1, promotes air circulation in the greenhouse, and lowers the temperature inside the greenhouse.

[0041] Alternatively, the air pipe 8 is connected to the air intake pipe 7 via a flexible hose. The air intake pipe 7 is connected to the cavity body. An air pump is installed on the air intake pipe 7, and the outlet of the air pump is connected to the air pipe 8. Hot air inside the cavity body is introduced into the air pipe 8 through the air pump and discharged through the densely distributed air outlets on the air pipe 8. This allows the air to fully contact the heat-collecting water in the temperature-regulating water wall before being discharged from the air outlets 2-3. This reduces the temperature of the upper space of the greenhouse, promotes air circulation in the greenhouse, and stores heat in the temperature-regulating water wall unit 2-1. When the temperature inside the greenhouse is low at night or in cold weather, the heat-collecting water stored in the temperature-regulating water wall unit 2-1 releases heat to help raise the temperature inside the greenhouse.

[0042] Specifically, the air pipe 8 includes a first section and a second section, which are set at a right angle. The second section is densely covered with multiple air outlets. Hot air from the outside space is discharged into the temperature-regulating water wall unit 2-1 through the air outlets, and heats the heat-collecting water inside the temperature-regulating water wall unit 2-1. The air inlet of the air pump is located in the upper space of the greenhouse, and the heat from the upper space of the greenhouse is conducted to the interior of the temperature-regulating water wall unit 2-1 through the air pump.

[0043] A flexible hose is provided above the first section, and the first section is connected to the air pump through the flexible hose to introduce hot air from the upper space of the greenhouse into the temperature-regulating water wall unit 2-1, thereby increasing the water temperature inside the temperature-regulating water wall unit 2-1.

[0044] An air outlet 2-3 is provided above the temperature-regulating water wall unit 2-1, and the hot air discharged into the temperature-regulating water wall unit 2-1 by the air pipe 8 is discharged from the air outlet 2-3.

[0045] The temperature-regulating water wall unit 2-1 is also provided with a first return water pipe 2-2, which is connected to the first circulating return water pipe. The heat collection water in the temperature-regulating water wall unit 2-1 circulates with the heat collection cavity 3 through the first circulating return water pipe.

[0046] It also includes a heat collection plate 6, which is disposed at the front end of the temperature regulating water wall 2, as shown in the figure. Figure 9The heat collection plate 6 contains heat collection water, and the heat collected by the heat collection plate 6 is stored in the heat collection water flowing through it. The heat collection plate 6 is connected to the temperature regulating water wall 2 via a circulating water pump, which guides the heat collection water in the heat collection plate 6 into the temperature regulating water wall 2. It has multiple heat storage modes. The water temperature in the heat storage module located at a higher altitude is higher, and more heat is released. When the temperature inside the greenhouse is low, heating equipment or electric heating is used to raise the temperature inside the greenhouse and save energy.

[0047] Specifically, the heat collection plate 6 comprises multiple adjacent heat collection plate units. Each heat collection plate unit is a blow-molded hollow plate with multiple strip-shaped holes. Multiple water collection pipes are evenly distributed on the blow-molded hollow plate, and the water collection pipes are filled with heat collection water. The heat collection plate units are designed to be entirely black or other dark colors that are conducive to absorbing sunlight, thereby improving the efficiency of the heat collection plate units in absorbing sunlight and enhancing their heat absorption effect. During the day, when the temperature inside the greenhouse is high, the heat collection plate 6 collects heat from the greenhouse and stores it in the temperature-regulating water wall 2. At night or in cold weather when the temperature inside the greenhouse is low, the heat collection water in the heat collection plate 6 releases heat to help raise the temperature inside the greenhouse. The heat collection water in the heat collection plate and the heat collection water in the temperature-regulating water wall circulate together, and the combination of multiple heat storage modes results in better heat storage effect. In cold weather, both the heat collection plate and the heat collection water in the temperature-regulating water wall can release heat, further enhancing the temperature increase effect inside the greenhouse.

[0048] Preferably, the surface of the heat collection plate unit is fitted with a solar glass cover, a PC solar panel, or a thin film, forming a cavity between the heat collection plate unit and the cover. This allows for full utilization of sunlight and efficient collection of solar heat to heat the heat collection water within the heat collection plate unit. Heat is then collected from inside the greenhouse via heat conduction. When the greenhouse temperature is high, the heat collection water inside the heat collection plate unit absorbs heat from the greenhouse interior, lowering the temperature. The heat is stored in the heat collection water within the heat collection plate unit. At night or during cold weather when the greenhouse temperature is low, the heat collection water releases heat to help raise the greenhouse temperature, promoting crop growth and saving energy.

[0049] The collector plate unit is equipped with a third return water pipe and a third outlet water pipe. The third return water pipe is located in the lower space of the collector plate unit and serves as the inlet pipe for the collector plate, through which the heat collection water enters the collector plate unit. The third outlet water pipe is located in the upper space of the collector plate unit. As the heat collection water flows from the lower space to the upper space of the collector plate unit, it absorbs heat from the collector plate unit through heat conduction and stores it in the temperature-regulating water wall.

[0050] The third return water pipe is connected to the first outlet water pipe, and the third outlet water pipe is connected to the first return water pipe, so that the heat collection water circulates between the heat collection plate 6 and the temperature regulating water wall 2.

[0051] Preferably, the heat collection cavity 3 is connected to the heat collection plate 6, and the heat collection plate 6 is connected to the temperature regulating water wall 2, further improving the heat storage performance of the greenhouse; at night or in cold weather, the heat collection water in the heat collection cavity 3, the heat collection plate 6 and the temperature regulating water wall 2 releases heat to help raise the temperature inside the greenhouse and improve the energy-saving performance of the greenhouse.

[0052] The temperature-regulating and humidity-retaining greenhouse is also equipped with an air heater. When the temperature inside the greenhouse is low, the air heater is turned on to increase the temperature. Because of the heat collection cavity 3, heat collection plate 6 and temperature-regulating water wall 2, the heat collection water in the heat collection cavity 3, heat collection plate 6 and temperature-regulating water wall 2 releases heat to help increase the temperature inside the greenhouse, thus saving energy when using the air heater to increase the temperature of the greenhouse.

[0053] Preferably, the temperature-controlled and humidity-retaining greenhouse is equipped with a temperature control module, which includes a temperature sensor and a control circuit. The control circuit is electrically connected to the temperature sensor, which detects the temperature inside the greenhouse in real time and transmits the detected temperature value to the control circuit. The control circuit is electrically connected to an air heater and an air pump. The control circuit is set with a temperature threshold. When the temperature inside the greenhouse reaches the set temperature threshold, the air pump automatically turns on, automatically drawing hot air from the upper part of the greenhouse into the heat collection cavity, promoting air circulation inside the greenhouse, reducing the temperature inside the greenhouse, and automatically increasing the humidity inside the greenhouse. When the temperature inside the greenhouse is lower than the set temperature threshold, the air heater automatically turns on, thereby achieving precise temperature control and humidity retention of the greenhouse interior, promoting crop growth.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
