Abstract
A rain shield for an exhaust duct solves the problem that a conventional device has a poor water-retaining effect, comprises a rain shield upper part and a rain shield lower part which are matched with each other, and is characterized in that the rain shield upper part and the rain shield lower part are mutually matched cones; a water-collecting tray is arranged in the rain shield, and a water drainage pipe leading to the outside of the rain shield is arranged at the bottom of the water-collecting tray; a water-retaining short pipe is sleeved with the bottom of the rain shield lower part and extends into the rain shield lower part, a water collecting tank is formed between the water-retaining short pipe and the rain shield lower part, and drain holes are formed in the water collecting tank in a position on the wall of the rain shield lower part. The rain shield is stable in structure and convenient to replace, and has a secondary rainproof function and a favorable water-retaining effect.
Description
Technical field
The utility model relates to a kind of rainhat, is a kind of exhaust duct rainhat specifically, is mainly used in preventing the rain leakage of exhaust duct outside.
Background technology
At present, along with industrial expansion, use for ventilation field is also frequent all the more, and some ventilating ducts need to carry out outdoor air draft, still, due to after pipeline goes out roofing, there is the roof leaking problem, pipe interior is caused to corrosion, cause pipeline minimizing in application life, there is numerous roof leaking hidden danger in the rainhat of traditional handicraft, easily causes the pipe interior corrosion.For this reason, need badly existing exhaust duct is improved with rainhat.
The utility model content
The purpose of this utility model is for a kind of exhaust duct rainhat is provided, and has solved the problem of existing apparatus dash weak effect, and its Stability Analysis of Structures, be convenient for changing, and have the rainproof effect of secondary, and the dash effect is good.
The technical scheme that the utility model adopts is: comprise rainhat top, the rainhat bottom of cooperation, rainhat top and rainhat bottom are the cone cylinder cooperatively interacted, and the rainhat upper buckle is combined on the rainhat bottom; And weld support portion in rainhat, and being provided with water-collecting tray in rainhat, the water-collecting tray bottom is provided with leads to the outer gutter of rainhat, and the water-collecting tray bottom is connected with gutter by elbow, and gutter runs through the rainhat lower part wall and reaches outside rainhat; The rainhat lower base is socketed in outside the dash short tube, and the part body of dash short tube stretches in the rainhat bottom, between dash short tube and rainhat bottom, forms catch basin, on the rainhat lower part wall of catch basin, is provided with drain hole; Dash short tube bottom is connected with the bottom pipeline by flange.
Described water-collecting tray is inverted cone cylinder.
The upper opening bore of described water-collecting tray is greater than the caliber of dash short tube.
The advantage the utlity model has and positive technique effect are: rainhat top and rainhat bottom are the cone cylinder cooperatively interacted, coordinate closely, and good looking appearance, the effect of keeping off the rain is strong.Be provided with water-collecting tray in rainhat, the water-collecting tray bottom is provided with leads to the outer gutter of rainhat, and most of rainwater collects rear discharge by water-collecting tray.The rainhat lower base is socketed in outside the dash short tube, the dash short tube stretches in the rainhat bottom, between dash short tube and rainhat bottom, forms catch basin, on the rainhat lower part wall of catch basin, is provided with drain hole, the small part rainwater collects in catch basin discharges, and realizes that secondary is rainproof.Production technology is simple, with low cost, rainproof effective.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Sequence number explanation in figure: 1, rainhat top, 2, water-collecting tray, 3, elbow, 4, support portion, 5, gutter, 6, the rainhat bottom, 7, the dash short tube, 8, flange.
The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.This exhaust duct comprises the parts such as the rainhat top 1, rainhat bottom 6 of cooperation with rainhat.Rainhat top 1 and the cone cylinder of rainhat bottom 6 for cooperatively interacting, rainhat top 1 is fastened on rainhat bottom 6, and after coordinating, outer likeness in form flying saucer, do not affect the appearance.And weld support portion 4 in rainhat, improve the integrally-built stability of rainhat.Be provided with water-collecting tray 2 in rainhat, water-collecting tray 2 bottoms are provided with leads to the outer gutter 5 of rainhat, and water-collecting tray 2 bottoms are connected with gutter 5 by elbow 3, and gutter 5 runs through bottom or the rainhat top wall reaches outside rainhat.6 bottoms, rainhat bottom are socketed in outside dash short tube 7, and the part body of dash short tube 7 stretches in rainhat bottom 6, can between dash short tube 7 and rainhat bottom 6, form catch basin, on 6 walls of the rainhat bottom of catch basin, are provided with drain hole.Water-collecting tray 2 is inverted cone cylinder, and the upper opening bore of this cone cylinder is greater than the caliber of dash short tube 7.Can make most of rainwater fall into water-collecting tray 2, prevent in catch basin that the water yield is excessive and overflow and enter lower pipeline.Dash short tube 7 bottoms are connected with the bottom pipeline by flange 8, conveniently rainhat are changed.
Operating principle: rainwater enters in rainhat by the open top on rainhat top 1, and most of rainwater drops on water-collecting tray 2, and the small part rainwater drops on the inwall of rainhat bottom 6 inclinations.After most of rainwater collects by water-collecting tray 2, by gutter 5, discharge, the small part rainwater slides in catch basin under 6 inwalls of rainhat bottom, by the drain hole on catch basin, discharges.Realize that secondary is rainproof, prevent the corrosion of rainwater to pipeline.
The utility model is not limited to above-described embodiment, and equivalent concepts or change in any technical scope disclosed at the utility model, all classify protection domain of the present utility model as.
