As shown in fig. 13 and 14, the arch truss module 200 includes a hot air enrichment and transportation module 800, the arch unit 210 of the hot air enrichment and transportation module 800 is a tubular arch unit 2101, an air inlet hole 810 communicated with the arch truss module space 244 is provided on the tubular arch unit 2101, at least, a first spacing member 220 disposed at the bottom end of the truss portion 201 is a tubular first spacing member 2201, a lumen 601 of the tubular arch unit 2101 is communicated with the lumen 601 of the tubular first spacing member 2201, and air outlet holes 820 are provided along one side or two sides of the extending direction of the tubular first spacing member 2201 for connecting with a preset air delivery pipe pump system 830.

The air inlet hole 810 may be disposed on a side wall and/or a bottom wall (a wall of a relatively large area) of the tubular arch unit 2101, the air pipe pump system 830 extracts the hot air 900 in the tubular arch unit 2101 under negative pressure, and the hot air 900 is fed into a place where the hot air is needed under positive pressure, for example, the hot air 900 is injected into a loose soil depth through the soil air injection device 840, so that the soil temperature of the plant root system is increased while ventilation and oxygenation are performed for the plant root system, the temperature of the heat energy in the hot air 900 is reduced after the heat energy is absorbed by the soil, and the air with reduced temperature overflows from the soil and circulates back to the greenhouse space.

As shown in fig. 14, the center pillar 100 is a tubular center pillar 1001, the air pipe pump system 830 includes an air pipe 832 and a fan 831, the air pipe 832 is used for communicating the tubular center pillar 1001 with the tubular first distance member 2201, the soil gas injection device 840 is communicated with the lower end of the tubular center pillar 1001, and the hot air 900 flows into the soil gas injection device 840 through the tubular center pillar 1001, saving the air pipe used for connecting the tubular first distance member 2201 with the soil gas injection device 840.

It is prior art to supply hot air 900 from the interior space of the greenhouse into the greenhouse soil for increasing the temperature of the greenhouse soil. The advantage of the above solution is that the tubular arch units 2101 and the tubular first spacing members 2201 of the arch truss modules 200 are used together as a means for raising the soil greenhouse by using the heat energy in the hot air 900 of the greenhouse space in an organized manner, thereby saving the cost of a hardware device that needs to be additionally provided to perform this function.

As shown in fig. 15 and 17, the arch truss module 200 includes a heat collecting module 600, the arch unit 210 of the heat collecting module 600 is a tubular arch unit 2101, at least, the first spacing member 220 disposed at the bottom end of the truss portion 201 is a tubular first spacing member 2201, the lumen 601 of the tubular arch unit 2101 is in communication with the lumen 601 of the tubular first spacing member 2201, and at least, a water inlet and outlet hole 610 is provided along one side of the extending direction of the tubular first spacing member 2201 for connection with a preset water pipe pump system 620. When a temperature difference exists, heat energy in hot air 900 in arch truss module space 244 is transferred to cold water in pipe cavity 601 through the pipe wall of tubular arch unit 2101, so that the temperature of the cold water is raised to be hot water similar to the temperature of the air at the position. The preset water pipe pump system 620 may be connected to any hot water using 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 water in the pipe cavity of the tubular arch unit 2101 from being transferred to the outside of the multi-span greenhouse through the transparent building envelope 284 in the roof building envelope, a layer of pipe wall heat insulation structure 602 can be arranged between the transparent building envelope 284 and the tubular arch unit 2101, a heat insulation structure with set thickness can be adhered to a corresponding part of the tubular arch unit 2101, for example, a foaming polyurethane heat insulation structure layer is adhered to the corresponding part, and in order to enable the foaming polyurethane heat insulation structure layer to be combined with the pipe wall more firmly, a rough structure (such as a concave-convex structure) can be arranged at the corresponding part of the pipe wall.

The above technical solution has the advantages that the pipe cavity 601 of the tubular arch truss unit 2101 forming the arch truss module 200 is used as a container, water is used as a heat absorption medium to store heat, during the winter, the low-temperature water in the low-temperature water source is transferred into the pipe cavity 601 of the tubular arch truss unit 2101 in the arch truss module 200 through the preset water pipe pump system 620, the heat energy in the hot air 900 enriched in the arch truss module space 244 in the multi-span greenhouse during the sunny day is absorbed and accumulated in the water in the pipe cavity 601 of the tubular arch truss unit 2101, and after the set temperature is reached, the hot water in the pipe cavity 601 is transferred to a place needing hot water, for example, for hot water drip irrigation through the preset water pipe pump system 620, so as to increase the soil temperature; or into a water storage tank. After the tube cavity 601 of the tubular arch unit 2101 is emptied, water is continuously supplied to store heat, and the circulation is performed alternately. In order to fill the lumen 601 of the tubular arch unit 2101 or to empty the lumen 601 of the tubular arch unit 2101 of water, an air inlet and outlet valve is required to be arranged at the highest position of the tubular arch unit 2101.

Assuming that the cross section of the tube cavity 601 of the tubular arch unit 2101 is 3 cm by 7 cm, the length of the tubular arch unit 2101 is 14 m, the 1 arch truss module 200 is composed of 11 tubular arch units 2101, the 1 arch truss module 200 covers 100m of land, the tube cavity 601 of the 11 tubular arch units 2101 of the 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 one day in a multi-span greenhouse, and the 300 kg of hot water at about 50 ℃ can be used for maintaining the soil temperature of 100m of land at a set temperature every day.

As shown in fig. 16, the arch truss module 200 includes a running water heat collecting module 700, the running water heat collecting module 700 is disposed at the upper portion of the arch truss module space 244 and is suspended from the arch truss module 200 body by a running water heat collecting module connector 712, the running water heat collecting module 700 includes a running water cavity 701 and an elongated pipe 710, and the running water cavity 701 is in communication with the pipe cavity 601 of the tubular arch unit 2101.

The running water heat collecting module 700 is an air-water heat exchanging device. The top of the truss module space 244 of the multi-span greenhouse arch is very high in temperature in sunny days, even 60 ℃ can be reached, and when cold water to be heated passes through the running water cavity 701 of the running water heat collection module 700, the heat energy in the hot air 900 is absorbed through the wall of the running water cavity, and when the temperature reaches the preset temperature, the water pipe pump system 620 is used for discharging the running water cavity 701 to a preset position according to a preset scheme. The water cavity 701 can be drained in a plurality of ways, and can be returned in a primary way or can be drained from another water delivery pipe pump system.

The advantage of the above technical solution is that the running water heat collecting module 700 of the air-water heat exchanging device further increases the total heat exchanging surface area and heat collecting efficiency of the arch truss module 200 for heat collection, and improves the heat collecting function of the arch truss module 200, so that more hot water rich in heat energy can be produced in unit time, and the running water heat collecting module can be used for planting irrigation to raise the ground temperature and can also be used for maintaining the temperature of the multi-span greenhouse at night.

Illustratively, the flow cavity 701 of the flow water heat collection module 700 includes an elongated tube 710, the elongated tube 710 communicating with the lumen 601 of the tubular arch unit 2101 in parallel 711.

The elongated tube 710 is a conduit having a tube diameter that is substantially smaller than the tube length in order to provide the largest possible surface area of the flow lumen 701 per unit volume to facilitate heat exchange between the 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 effect.

The above technical solution has the advantages that the manufacturing process of the elongated tube 710 is simple, the heat exchange assembly using the elongated tube 710 as the running water heat collecting module 700 is simple in structure, the assembly cost is low, and the installation and replacement on the arch truss module 200 body are easy.

As shown in fig. 17 and 19, the multi-span greenhouse center pillar 100 is provided as a tubular center pillar 1001, and the heat storage cavity 1002 of the tubular center pillar 1001 is used as a container for storing hot water in the multi-span greenhouse, so that the container which is required to be separately provided originally can be saved.

If the area of the land enclosed by 4 tubular center pillars 1001 of the multi-span greenhouse is 100 m, the height of the space between the area and the expanded plugging structures 241 in the corresponding plugging modules 240 is 6 m, the height space is 600 cubic meters, and 774 Kg of air is contained, which requires 186 Kcal of heat energy per 1 deg.c rise (specific heat of air is 0.24Kcal/Kg deg.c, and specific heat of air is about 1.29Kg/m ³).

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