Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a technical solution:

[0025] Please refer to Figures 1 to 4 , a non-powered anti-negative pressure cooling daylighting device for the roof of a printing and dyeing factory building, including a factory building roof 1, a roof reserved steam hole 10 for exhausting steam is opened at the top of the factory building roof 1, a skeleton assembly 9 is covered above the factory building roof 1, and an external special-shaped rain shield 7 is installed on the surface of the skeleton assembly 9 through bolts. A total steam outlet 4 for discharging steam is arranged above the skeleton assembly 9, a flame-retardant daylighting board 8 fixed on the top of the skeleton assembly 9 is arranged below the total steam outlet 4, and a mixed steam outlet 3 is formed by enclosing the left and right sides of the flame-retardant daylighting board 8 and the skeleton assembly 9;

[0026] An outdoor fresh air diversion baffle 6 fixed on the left and right sides of the skeleton assembly 9 is further arranged above the factory building roof 1. An outdoor fresh air diversion inlet 5 is arranged outside the outdoor fresh air diversion baffle 6, and an indoor exhaust port 2 is arranged inside the outdoor fresh air diversion baffle 6.

[0027] By adopting the above technical scheme, the gas in the roof 1 of the factory building is discharged into the frame components 9 through the reserved steam outlet holes 10 on the roof. At this time, the external fresh air is introduced into the frame components 9 through the outdoor fresh air guide inlet 5, and flows upward along the outdoor fresh air guide baffle 6, so that a chimney effect is formed in the frame component 9. At this time, the gas in the roof 1 of the factory building is mixed with the fresh air through the indoor exhaust port 2 and discharged from the mixed steam outlet 3, and finally quickly discharged outwardly through the total steam outlet 4. Since the air inlet area is increased through the outdoor fresh air guide inlet 5, the cooling effect is obvious in high temperature seasons, and the fog will not flow back into the room in winter. Since the fog can be discharged quickly, the formation of condensation water droplets on the equipment can be avoided. At the same time, rainwater can be discharged outwardly along the external special-shaped rain shield 7, and part of the rainwater can be collected on the flame retardant lighting board 8, thereby avoiding rainwater from entering. The entire device can achieve gas discharge without using an exhaust fan, saving the operating cost of the fan.

[0028] Specifically, Figure 2 As shown, the skeleton component 9 includes a basic skeleton 901 of a "冂"-shaped structure welded by SUS304 stainless steel square tubes, and outer frames 903 of a zigzag structure are welded on both sides of the basic skeleton 901. A horizontally arranged transverse strut 902 is arranged between the outer frame 903 and the basic skeleton 901, and a longitudinal strut 904 fixed below the outer frame 903 is welded above the transverse strut 902. A slanted reinforcing rod 905 is arranged between the longitudinal strut 904 and the basic skeleton 901, and the skeleton components 9 are all welded by SUS304 stainless steel square tubes of different lengths.

[0029] By adopting the above technical scheme, since the printing and dyeing factory is humid and easy to corrode, the skeleton components 9 are all made of SUS304 stainless steel square tubes, which are welded and manufactured in the factory to facilitate subsequent transportation and lifting. The skeleton components 9 are provided with multiple groups, and each group of single-piece skeleton components 9 is arranged on the purlins of the factory roof 1 that can bear the load. The skeleton components 9 are connected according to the actual situation. The skeleton spacing is determined according to the purlin spacing of the factory roof 1. The maximum spacing is not easy to be greater than 3 spans of purlins or 3.75m. The two top ends of the device after installation are closed, and the roof reserved steam vents 10 are retained between the skeleton components 9 and the factory roof 1. The gas in the factory roof 1 can enter the skeleton components 9 through the roof reserved steam vents 10, and diffuse outward through the skeleton components 9 with special structures.

[0030] Specifically, Figure 3As shown in the figure, the lower part of the indoor exhaust port 2 is lower than the upper part of the outdoor fresh air diversion baffle 6, and the indoor exhaust port 2 is located on the left and right sides of the basic framework 901. The flame-retardant lighting board 8 is located in the area surrounded by the basic framework 901 and the strengthening rod 905. The external special-shaped rain baffle 7 is integrally formed. A fixing bolt 11 is inserted through the connection between the basic framework 901 and the factory roof 1, and an anti-slip pad 12 is movably connected to the outside of the fixing bolt 11. The anti-slip pad 12 is located at the connection between the basic framework 901 and the factory roof 1.

[0031] By adopting the above technical solution, through the outdoor fresh air diversion baffle 6, the fresh air on the roof is diverted into the inner side of the framework assembly 9. Under the action of the outdoor fresh air diversion baffle 6, a chimney effect is formed upwards, driving the high-temperature moisture in the room to form a mixed gas and exhausting it outwards from the indoor exhaust port 2 at the top of the device. In winter, when negative pressure is generated on the roof, under the action of the outdoor fresh air diversion baffle 6, the formed chimney effect prevents the outdoor wet air from flowing back. And in cooperation with the external special-shaped rain baffle 7, it effectively prevents rainwater from entering. The external special-shaped rain baffle 7 is an integral whole from top to bottom, and there is no gap between the folded lines, thus preventing the fresh air from short-circuiting and affecting the chimney effect. The outdoor fresh air diversion inlet 5 must be lower than the upper edge of the outdoor fresh air diversion baffle 6 to prevent affecting the chimney effect.

[0032] Working principle: The gas in the factory roof 1 is discharged into the space between the framework assemblies 9 through the steam outlet holes 10 reserved on the roof. At this time, the external fresh air is introduced into the framework assembly 9 through the outdoor fresh air diversion inlet 5 and flows upwards along the outdoor fresh air diversion baffle 6, forming a chimney effect in the framework assembly 9. At this time, the gas in the factory roof 1 is discharged outwards quickly through the mixed steam outlet 3 after being mixed with the fresh air at the indoor exhaust port 2. Finally, it is discharged outwards quickly through the total steam outlet 4. Since the air inlet area is increased through the outdoor fresh air diversion inlet 5, the cooling effect is obvious in the high-temperature season, and the fog will not flow back in winter. Since the fog can be discharged quickly, the formation of condensed water dripping onto the equipment can be avoided. The external special-shaped rain baffle 7 is in a tile-like structure and is stacked layer by layer. The rainwater can flow outwards along the external special-shaped rain baffle 7. Part of the rainwater entering through the total steam outlet 4 can be collected on the flame-retardant lighting board 8. The two sides of the flame-retardant lighting board 8 are higher than the middle part, thus avoiding the rainwater from being discharged through the mixed steam outlet 3. A drain pipe can also be set on the flame-retardant lighting board 8 to discharge the rainwater on the flame-retardant lighting board 8. The flame-retardant lighting board 8 adopts a double-layer PC (polycarbonate) hollow 1 diffused flame-retardant sunlight board. The sunlight can enter through the flame-retardant lighting board 8 to achieve lighting. And a stainless steel plain woven mesh can be covered on the indoor exhaust port 2 to prevent insects and birds from entering. The whole device is firmly installed on the factory roof 1 to prevent it from being overturned by typhoons.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
