Abstract

The utility model discloses a rain-proof hood, include: a wind cap cover, a wind cap cylinder and a cylindrical waterproof baffle; the blast cap cylinder is arranged on the mounting plate, and a ventilation opening is formed in the side wall of the blast cap cylinder; the wind cap cover is arranged at the top of the wind cap cylinder and seals the top of the wind cap cylinder; the waterproof baffle is arranged on the outer side of the hood barrel in a surrounding manner, and the edge of the hood cover extends towards one side of the mounting plate and covers the waterproof baffle; the distance L1 from the edge of the hood cover to the mounting plate is less than the distance L2 from the top of the flashing to the mounting plate. When the rain-proof hood is arranged on the side wall of an object and the opening direction of the ventilation opening arranged on the hood barrel is upward, the waterproof structure formed by the hood cover and the barrel-shaped waterproof baffle can prevent rainwater from flowing into the ventilation opening.

Description

Rain-proof hood

Technical Field

The utility model relates to a hood, in particular to a rain-proof hood.

Background

In current ventilation system, often need set up the hood at the vent, play rain-proof circumstances such as debris drop of preventing. However, in actual use, foreign matters such as dust, sundries and insects still enter the ventilation opening.

In order to prevent the above-mentioned situation, as in the prior art with publication number CN 26286247U, a louver is disposed on the side wall for ventilation, so as to achieve the technical effects of preventing the entry of foreign matters and the entry of rainwater. However, the current technical solutions are often focused on enhancing the waterproof and dustproof performance of the vertically installed ventilation opening. And some special equipment, like the fan, need install in the fan lateral wall setting up the hood, use a hood section of thick bamboo lateral wall vent direction upwards, traditional waterproof technology can't reach waterproof dustproof effect at this moment.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model aims at providing a rain-proof hood with better water-proof effects.

In order to achieve the above object, the utility model discloses a rain-proof hood, include: a wind cap cover, a wind cap cylinder and a cylindrical waterproof baffle; the blast cap cylinder is arranged on the mounting plate, and a ventilation opening is formed in the side wall of the blast cap cylinder; the wind cap cover is arranged at the top of the wind cap cylinder and seals the top of the wind cap cylinder; the waterproof baffle is arranged on the outer side of the hood barrel in a surrounding manner, and the edge of the hood cover extends towards one side of the mounting plate and covers the waterproof baffle; the distance L1 from the edge of the hood cover to the mounting plate is less than the distance L2 from the top of the flashing to the mounting plate.

One end of the waterproof baffle, which is far away from the mounting plate, inclines to the radial outer side.

The included angle between the waterproof baffle and the surface of the mounting plate is 45 degrees to 90 degrees.

The top end of the waterproof baffle is provided with an eaves part which is bent outwards.

The vent includes a plurality of vents.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that:

the side face is additionally provided with the waterproof baffle plate, so that rainwater or sundries are prevented from permeating into the fan cabin from the air opening formed in the air cap barrel when the air cap is installed on the side wall of an object. The waterproof baffle is installed in an outward inclining mode, the top end of the waterproof baffle is provided with an outward bending radian, rainwater is prevented from flowing into the air duct cap along the baffle when the waterproof baffle is used, and the waterproof effect is better.

Drawings

Fig. 1 is a schematic view of a rain hood for a wind turbine.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model discloses a rain-proof hood, include: the wind cap comprises a wind cap cover 1, a wind cap barrel 2 and a cylindrical waterproof baffle 3; the wind cap cylinder 2 is arranged on the mounting plate 4, and a plurality of ventilation holes 5 are formed in the side wall of the wind cap cylinder 2; the wind cap cover 1 is arranged at the top of the wind cap cylinder 2 and seals the top of the wind cap cylinder 2; the waterproof baffle 3 is arranged on the outer side of the hood barrel 2 in a surrounding manner; one end of the waterproof baffle 3, which is far away from the mounting plate 4, inclines to the radial outer side and forms an included angle of 70 degrees with the mounting plate 4; the top end of the waterproof baffle 3 is provided with an eaves part bending outwards. The edge of the wind cap cover 1 extends towards one side of the mounting plate 4 and covers the waterproof baffle plate 3; the distance L1 from the edge of the weather cap 1 to the mounting plate 4 is less than the distance L2 from the top of the flashing 3 to the mounting plate 4.

This rain-proof hood adopts the side to add and establishes waterproof baffle 3, is when preventing that rain-proof hood from installing the object lateral wall, and the wind hole 5 infiltration fan under-deck is opened from hood section of thick bamboo 2 to rainwater or debris. 3 extroversion installations of waterproof baffle, the radian of incurving prevent that the rainwater from flowing into the wind barrel cap along the baffle when using in the top, and water-proof effects is better.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
