Technical Field
[0001] The utility model relates to the technical field of agricultural arch sheds, in particular to a connected arch shed with good ventilation and heat dissipation performance. Background Art
[0002] The conjoined arch shed is a type of shed that runs north-south. Its advantages include high land utilization, little land waste, low cost, good insulation effect, and is suitable for areas above -20 degrees Celsius. The disadvantage of this type of shed is that it has high land requirements, generally requiring a width of more than 50 meters and an expandable length. The conjoined arch shed is different from the single arch shed. It is an independent design in recent years. It can be covered with a thermal blanket, has better insulation performance, is more outstanding in terms of land utilization area, and has a very low cost. However, its construction is difficult and safety is of paramount importance. The conjoined arch shed connects the individual arch sheds through the gutter, making the overall internal growth environment of the arch shed more stable and less susceptible to the external environment. This type of shed has certain spatial advantages and strong snow and wind resistance. The specifications and quantity of components such as the columns, beams, gutters and arch rods of the arch shed are determined according to the specific design to ensure the stability and safety of the structure.
[0003] The existing connected arch sheds are generally many arches connected together, and the coverage area of the entire connected arch shed is extremely large. The ventilation and heat dissipation are poor during the high temperature period in summer, which is not conducive to the growth of crops in the middle of the arch shed. In addition, it is difficult for transport vehicles to directly enter the arch shed. The vegetables inside have to be transported outward by manpower or small carts, which makes circulation and management difficult. In addition, multiple arches are connected together, the overall volume is large, and the construction is difficult.
[0004] Therefore, in order to solve the above problems, a connected arch shed with good ventilation and heat dissipation performance is proposed. Utility Model Content

Moreover, the internal structure of the second multi-span greenhouse group 2 is the same as that of the first multi-span greenhouse group 1.
[0027] As Figure 1 And Figure 4 shown, a multi-span greenhouse with good ventilation and heat dissipation performance. The support framework assembly 11 divides the entire multi-span greenhouse into multi-span greenhouses in groups of three arches, which is convenient for improving the ventilation performance inside the greenhouse, thereby cooling down and providing a good growth environment for vegetables. The support framework assembly 11 includes arch support vertical rods 111. The top of the arch support vertical rods 111 is welded and connected to an arch support cross beam 112. And the top of the arch support cross beam 112 is welded and connected to a cross-shaped support framework 113. The top of the cross-shaped support framework 113 is welded and connected to a top support arch 114. And a covering film 115 is installed outside the top support arch 114. The shape of the top support arch 114 is set as a circular arc, and three top support arches 114 are arranged at equal intervals with respect to the bottom of the covering film 115. The materials of the arch support vertical rods 111, the arch support cross beam 112, the cross-shaped support framework 113, and the top support arch 114 are all set as lightweight steel materials. The material of the covering film 115 is set as polyolefin PO film, and the thickness of the covering film 115 is set to ten silk. A ventilation channel with a width of two meters is arranged between each two groups. Under the action of the two side greenhouses, a pipe effect will be formed inside this ventilation channel, enabling natural wind to flow through the channel and then enter the interior of the multi-span greenhouse through the air vents. Compared with the traditional integral multi-span greenhouse, the way of three arches in a group is convenient for increasing the air fluidity and shortening the distance between the middle vegetables and the ventilation openings. Thus, in the hot summer, it can also ensure a relatively suitable temperature for vegetables, facilitating the prevention of excessive temperature from damaging the growth of vegetables. Moreover, the reserved channels between each two groups of multi-span greenhouses enable vehicles to pass through, facilitating the outward transportation of the picked vegetables and saving manpower.
[0028] As Figure 3 , Figure 5 and Figure 6 shown, a connected arch shed with good ventilation and heat dissipation performance, the micro-spray cooling component 12 is used to spray water mist inside the arch shed to assist in cooling in summer. The micro-spray cooling component 12 includes a water delivery pipe 121, a fixing strap 122 is bundled outside the water delivery pipe 121, and water outlet holes 123 are opened at the bottom of the water delivery pipe 121. An insertion block 124 is closely attached to the inner wall of the water outlet hole 123, and a bottom limiting block 125 is closely attached to the outer wall of the water outlet hole 123. The bottom of the insertion block 124 is fixedly connected to a micro-spray pipe 126, and a rotary nozzle 127 is installed at the bottom of the micro-spray pipe 126. The water delivery pipe 121 and the arch shed support cross beam 112 form a detachable structure through the fixing strap 122, and three water delivery pipes 121 are equidistantly arranged about the bottom of the arch shed support cross beam 112. A water passing hole is opened inside the insertion block 124, and the material of the insertion block 124 is set as a silica gel material. The water delivery pipe 121, the water outlet hole 123, the insertion block 124, the micro-spray pipe 126 and the rotary nozzle 127 form a communication structure, and the water outlet holes 123 are equidistantly arranged about the bottom of the water delivery pipe 121. The water delivery pipe 121 is erected inside the arch shed, which is convenient for guiding the water flow from the water source to the inside of the arch shed, and a plurality of rotary nozzles 127 are equidistantly arranged. When it rotates and sprays, it can achieve full coverage inside the arch shed, which is convenient for watering the vegetables inside the arch shed. Moreover, the micro-spray technology from top to bottom can further cool the inside of the arch shed in summer, providing a good growth environment for the vegetables.
[0029] Working principle: This connected arch shed has three arches as a group. The support skeletons between adjacent two arches inside each group are welded together. A whole covering film 115 is installed and covered outside a group of arch sheds, and the films on both sides of the connected arch shed are both provided with air vents two meters wide. Outside the air vents, there are films controlled by electric rolling film devices for winding and unwinding, and the size of the air vents can be adjusted according to different seasons;

Under the action of the two side arch sheds, a pipe effect will be formed inside this ventilation channel, enabling natural wind to flow through the channel and then enter the inside of the connected arch shed through the air vents;
[0031] The fixing tie 122 made of wire can be used to bundle and fix the water delivery pipe 121 to the arch shed support cross beam 112. After the installation and fixation of the water delivery pipe 121 are completed, the operator can use tools such as a drill to equally space and open water outlet holes 123 at the bottom of the water delivery pipe 121, and insert the insertion block 124 into the interior of the water delivery pipe 121 through the water outlet holes 123. The tail end of the water delivery pipe 121 is connected to a water pump and a water supply place, which can supply water to each rotating sprinkler 127, and then spray water mist down to spray water on the vegetables below for cooling. The direction of the water delivery pipe 121 is consistent with the direction of each arch shed, and considering the spraying distance of the rotating sprinkler 127, three groups of parallel water delivery pipes 121 are arranged below each arch shed, which can achieve full coverage of water spraying inside the arch shed.
