It is prior art to introduce hot air 900 into the greenhouse soil for raising the temperature of the greenhouse soil. The advantage of the above-mentioned technical solution is that the tubular arch unit 2101 of the arch truss module 200 and the tubular first distance member 2201 cooperate as a means for organically utilizing the heat energy in the hot air 900 of the greenhouse space to raise the soil greenhouse, which saves the cost of an additional set of hardware devices that would otherwise be required to perform this function.

As shown in fig. 15 and 17, the arch truss module 200 includes a tube-in-water heat collection module 600, the arch unit 210 of the tube-in-water heat collection module 600 is a tubular arch unit 2101, at least the first distance member 220 disposed at the bottom end of the truss portion 201 is a tubular first distance member 2201, a lumen 601 of the tubular arch unit 2101 is communicated with a lumen 601 of the tubular first distance member 2201, and at least one water inlet and outlet hole 610 is disposed along one side of the tubular first distance member 2201 in the extending direction for connecting with a preset water pipe pump system 620. When temperature difference exists, heat energy in hot air 900 in the arch truss module space 244 is transferred to cold water in the pipe cavity 601 through the pipe wall of the tubular arch unit 2101, and the cold water is heated to become hot water with the temperature close to that of the air at the position. The predetermined water pipe pump system 620 may be connected to any hot water supply device 630 in the multi-span greenhouse, for example, to an irrigation system, or to a hot water storage container.

In order to prevent heat energy in the pipe cavity water of the tubular arch unit 2101 from transferring to the outside of the multi-span greenhouse through the transparent enclosure 284 in the roof enclosure, a pipe wall heat insulation structure 602 may be arranged between the transparent enclosure 284 and the tubular arch unit 2101, or a heat insulation structure with a set thickness may be bonded to a corresponding part of the tubular arch unit 2101, for example, a foamed polyurethane heat insulation structure layer may be bonded to the corresponding part, and in order to make the foamed polyurethane heat insulation structure layer and the pipe wall be bonded more firmly, a rough structure (for example, a concave-convex structure) may be arranged at the corresponding part of the pipe wall.

The technical scheme has the advantages that the tube cavity 601 of the tubular arch unit 2101 forming the arch truss module 200 is used as a container, water is used as a heat absorbing medium for storing water and collecting heat in winter and daytime, low-temperature water in a low-temperature water source is transferred into the tube cavity 601 of the tubular arch unit 2101 in the arch truss module 200 through the preset water pipe pump system 620, heat energy in hot air 900 enriched in sunny day time in the arch truss module space 244 inside the multi-span greenhouse is absorbed and accumulated in the water in the tube cavity 601 of the tubular arch unit 2101, and after the set temperature is reached, the hot water in the tube cavity 601 is transferred to a place needing hot water through the preset water pipe pump system 620, for example, the hot water is used for hot water drip irrigation, and the soil temperature is increased; or input into the hot water storage container. After the tube cavity 601 of the tubular arch unit 2101 is emptied, the water supply and heat storage are continued, and the circulation is alternated. In order to fill the tubular arch unit 2101 with water or to empty the tubular arch unit 2101 from the water in the lumen 601, an air inlet and outlet valve is required at the highest position of the tubular arch unit 2101.

Assuming that the cross section of the tubular arch unit 2101 lumen 601 is 3 cm x 7 cm, the tubular arch unit 2101 is 14 m long, 1 arch truss module 200 is composed of 11 tubular arch units 2101, 1 arch truss module 200 covers 100 m of the ground, the lumen 601 of 11 tubular arch units 2101 of 1 arch truss module 200 can hold 300 kg of water at a time, the arch truss module 200 can heat 300 kg of water to about 50 ℃ in a multi-span greenhouse in one day, and the 300 kg of water and the 50 ℃ of hot water can be used to maintain the soil temperature of 100 m of the ground at a set temperature condition every day.

As shown in fig. 16, the arch truss module 200 includes a flowing water heat collecting module 700, the flowing water heat collecting module 700 is arranged at the upper part of the arch truss module space 244 and is suspended from the body of the arch truss module 200 through a flowing water heat collecting module connecting piece 712, the flowing water heat collecting module 700 includes a flowing water cavity 701 and a slender pipe 710, and the flowing water cavity 701 is communicated with the pipe cavity 601 of the tubular arch unit 2101.

The flowing water heat collecting module 700 is an air-water heat exchanging device. The air temperature at the top of the truss module space 244 of the multi-span greenhouse arch frame is very high in a fine day, even can reach 60 ℃, cold water to be heated absorbs heat energy in hot air 900 through the wall of the flowing water cavity to be heated in the process of passing through the flowing water cavity 701 of the flowing water heat collection module 700, and when the temperature reaches a preset temperature, the cold water is discharged from the flowing water cavity 701 to a preset part through the water pipe pump system 620 according to a preset scheme. The drainage from the flow cavity 701 may be performed in a variety of ways, either by returning the flow path or by flowing away from another water delivery pump system.

The advantage of the above technical solution is that the flowing water heat collecting module 700 of the air-water heat exchange device is used to further increase the total heat exchange surface area and heat collecting efficiency of the arch truss module 200 for heat collection, and improve the heat collecting function of the arch truss module 200, so as to produce more hot water rich in heat energy in unit time, which can be used for planting, irrigating and raising ground temperature, and can also be used for maintaining the air temperature of a multi-span greenhouse at night.

Exemplarily, the flowing water cavity 701 of the flowing water heat collecting module 700 comprises an elongated tube 710, and the elongated tube 710 is communicated with the tube cavity 601 of the tubular arch unit 2101 in a parallel connection 711.

The elongated tube 710 is a pipe having a diameter substantially smaller than the length of the tube, so that the water flowing cavity 701 has a surface area as large as possible per unit volume to facilitate heat exchange between water and the hot air 900. The thinner the wall of the elongated tube 710, the greater the thermal conductivity of the material comprising the wall, and the better the heat exchange.

The technical scheme has the advantages that the slender tube 710 is simple in manufacturing process, the slender tube 710 used as a heat exchange component of the running water heat collection module 700 is simple in structure and low in assembly cost, and the slender tube 710 is easy to install and replace on the arch truss module 200 body.

If there are 4 greenhousesThe area of the ground enclosed by the tubular central column 1001 is 100 square meters, the height of the space between the area and the blocking structure 241 unfolded in the corresponding blocking module 240 is 6 meters, the height space is 600 cubic meters, 774 kilograms of air are contained, 186 kilocalories of heat energy are needed for every 1 ℃ rise of the air (the specific heat of the air is 0.24Kcal/Kg ℃, and the specific gravity of the air is about 1.29Kg/m ³ )。

If the inner diameter of the tubular center pillar 1001 for storing hot water is 30 cm, 423 kg of hot water is stored in 1 tubular center pillar 1001, 423 kcal of heat energy is released when the temperature is reduced by 1 ℃, and the heat energy in 2 tubular center pillars 1001 is used for slowing down 774 kg of air temperature reduction, and 4.5 ℃ of temperature reduction can be slowed down.
