Embodiment 1

[0024] see Figure 1-4 , the sloping roof roof hood structure of the present invention includes a support cylinder 1, which plays the role of fixing and supporting the fixing rod 2. The bottom of the support cylinder 1 is inclined and arranged to facilitate the discharge of rainwater and the water sprayed by the sprinkler 6 out of the support cylinder 1. Inside, the top of the support cylinder 1 is provided with several fixing rods 2, which play the role of supporting the connecting shaft 3. The interior of the fixing rod 2 is provided with a connecting shaft 3, which plays the role of supporting the hood 4. The connecting shaft 3 and the number of The middle of each fixing rod 2 is connected in rotation.

[0025] The top of the connecting shaft 3 is provided with a hood 4, which automatically rotates when there is wind, and plays the role of ventilating the room. When the hood rotates, it drives the insect net to rotate, which effectively reduces the speed of dust accumulati...

Abstract

A sloping roof out-roof hood structure, comprising a support cylinder (1), characterized in that: the top of the support cylinder (1) is provided with a plurality of fixing rods (2), and the interior of the fixing rods is provided with a connecting shaft (3), the connecting shaft and the middle part of the fixing rod (2) are rotatably connected, the top of the connecting shaft is provided with a hood (4), and the bottom end of the fixing rod (2) is provided with several nozzles (6) , the bottom end of the connecting shaft (3) is provided with an insect-proof net (5), the right end of the bottom of the support cylinder is provided with a ventilation pipe (7), and the left end of the bottom of the support cylinder (1) is provided with a drainage pipe ( 8). The sloping roof out-roof hood structure of the invention has the advantages of preventing a large amount of sundries and insects from entering the ventilation duct, the rotation of the hood can drive the rotation of the insect-proof net, reducing the speed of dust accumulation, ensuring the cleaning of the insect-proof net and verifying the ventilation effect of the ventilation duct. .

Description

technical field [0001] The invention relates to a roof hood, in particular to a sloping roof out-roof hood structure. Background technique [0002] Ventilation duct is the abbreviation of ventilation duct, which is metal or non-metallic duct used in ventilation and air-conditioning engineering of industrial and civil buildings. Ventilation ducts are a kind of municipal infrastructure to circulate air and reduce the concentration of harmful gases. The hood, one of the ventilation equipment, is installed on the vent or exhaust pipe, and is mainly used for indoor ventilation. The insect-proof net inside the hood is easily blocked by sundries, insects and a large amount of accumulated dust, which will seriously affect ventilation. effect, and it is extremely difficult for high-rise buildings to clean and replace insect screens. [0003] Therefore, the known hood structure suffers from the above-mentioned inconveniences and problems. SUMMARY OF THE INVENTION [0004] The pur...
