it should be noted that: the top of the flue extension 4 needs to be higher than the plane of the first flue gas channel 316, typically above 20 MM.
In this embodiment, the flow direction of flue gas is as shown by the arrow in fig. 4, and the flue gas flows out the back from the top of flue extension section 4, because the upper end has the restriction of a shell 31, so the flue gas can be to diffusion all around, and then flows in between protection dustcoat subassembly 1 and the waterproof inner cover subassembly 3 through setting up first flue gas runner 316 all around, and because all around of protection dustcoat subassembly 1 are the baffle, only the upper surface is the protection network, therefore the protection network that the upper surface can be followed to the flue gas upwards discharges.
In addition, in the embodiment, due to the arrangement of the flue extension section 4, the flow velocity is not greatly changed in the process of flowing the flue gas into the main machine, so that compared with the existing fan scheme (due to the existence of the main machine base), the resistance influence of the part can be effectively reduced.
In this embodiment, the flow direction of the rainwater or other impurities is:
rainwater enters from the protective net on the upper surface of the protective outer cover component 1, diffuses around along the upper surface of the top cover 31, and then flows downwards along the side surfaces, and the rainwater on the side surfaces can flow into the water collecting unit 33 through the first outer water falling port 313 arranged on the first outer extension surface 312; of course, part of the rainwater flowing into the top cover 31 through the first flue gas flow channel 316 flows into the water collecting unit 33 through the first inner water falling port 315 formed on the first inner extending surface 314; in this way, the collection of rainwater is achieved.
The other structure of the waterproof inner cover component 3 is as follows:
as shown in fig. 5-7, it still includes a top shell 31 and a connecting pipe 32, the top shell 31 is covered on the connecting pipe 32 for preventing the impurities from flowing into the flue extension 4 through the connecting pipe 32; the waterproof inner cover assembly 3 further includes a water collecting unit 33, and the water collecting unit 33 is disposed at a lower portion of the top case 31 for collecting rainwater flowing down from the top case 31.
The top shell 31 includes a second body 3101 with a narrow top and a wide bottom, the bottom of the second body 3101 extends around to form a second outer extension surface 3102, the second outer extension surface 3102 is provided with a second outer water falling port 3103, the bottom of the second body 3101 extends towards the center to form a second inner extension surface 3104, the second inner extension surface 3104 is provided with a second inner water falling port 3105, the side surface of the second body 3101 is further provided with a second flue gas channel 3106, and a guide plate 3107 is arranged above the second flue gas channel 3106;
the guide plate 3107 is in an inverted V-shaped structure, and the length of the guide plate along the horizontal direction is greater than that of the second flue gas channel 3106;
unlike the first configuration, the second flue gas flow path 3106 in the second configuration is provided with only one layer and includes a deflector;
in order to meet the requirement of waterproof grade, a guide plate 3107 is arranged above a second flue gas flow channel 3106 in the second structure, and the guide plate 3107 is inverted V-shaped, so that a certain inclination angle a is ensured, and rainwater flows down smoothly;
in addition, the length of the flow guide plate 3107 in the horizontal direction is greater than the length of the second flue gas channel 3106, typically more than 10mm, which is significant in ensuring that rainwater flowing down the flow guide plate 3107 does not flow into the second flue gas channel 3106.
In this embodiment, the flow direction of flue gas is as shown by the arrow in fig. 7, and after the flue gas flowed out from the top of flue extension section 4, because there is the restriction of top shell 31 the upper end, consequently the flue gas can be to diffusion all around, and then flows into between protection dustcoat subassembly 1 and the waterproof inner cover subassembly 3 through setting up second flue gas runner 3106 all around, and because all around of protection dustcoat subassembly 1 are the baffle, only the upper surface is the protection network, therefore the protection network that the upper surface can be followed to the flue gas upwards discharges.
In this embodiment, the flow direction of the rainwater or other impurities is:
rainwater enters from the protective net on the upper surface of the protective housing assembly 1, diffuses around along the upper surface of the top cover 31, flows downwards along the side surface, and is collected by the guide plate 3107 arranged on the side surface, and because the guide plate 3107 is in an inverted V-shaped structure, the rainwater flows downwards along two ends of the guide plate 3107, and then flows into the water collection unit 33 through the second outer water falling port 3103 arranged on the second outer extension surface 3102; of course, part of the rainwater flowing into the top cover 31 through the second flue gas channel 3106 flows into the water collecting unit 33 through the second inner water falling hole 3105 formed on the second inner extension surface 3104; in this way, the collection of rainwater is achieved.
In one embodiment:
as shown in fig. 8, the water collecting unit 33 includes a water collecting chassis 331, a water outlet 332, a water volume meter 333 and a solenoid valve 334, wherein the water outlet 332 is disposed at one side of the water collecting chassis 331, the solenoid valve 334 is disposed at the water outlet 332 for controlling the opening or closing of the water outlet 332, the water volume meter 333 is disposed in the water collecting chassis 331 for detecting water flow, and controlling the state of the solenoid valve 334 according to the water flow;
therefore, rainwater flows into the water collecting base plate 331 through the top shell 31, and when the rainwater in the water collecting base plate 331 reaches a certain amount, the rainwater is discharged through the water outlet 332;
in addition, in order to avoid air leakage of the fan structure caused by the water outlet 332, when the water volume meter 333 identifies that the water volume in the water collection chassis 331 is enough to block the height of the water outlet 332, the electromagnetic valve 334 is opened, otherwise, the electromagnetic valve is closed.
In a specific embodiment:
the fan body 2 has a waterproof grade above IP6, and when the fan body is a centrifugal fan, a water guide hole 21 is formed in the bottom of a volute of the centrifugal fan.
The working process of the fan structure provided by the embodiment is as follows:
under fan body 2's effect, during flue gas got into connecting pipe 32 through flue extension section 4, because the upper end has the restriction of a shell 31, consequently the flue gas can be to diffusion all around, and then flows into between protection dustcoat subassembly 1 and the waterproof inner cover subassembly 3 through setting up at first flue gas runner 316 or second flue gas runner 3106 all around, and because be the baffle all around of protection dustcoat subassembly 1, only the upper surface is the protection network, consequently the protection network that the upper surface can be followed to the flue gas upwards discharges.
