Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heating and ventilation, especially relates to a skylight for factory building, specifically a ventilating skylight capable of effectively preventing water leakage in stormy weather. BACKGROUND

[0002] The skylight has the functions of lighting, ventilation and rainproofing in the factory building, and the types of the skylight mainly include rectangular skylight, rectangular windproof skylight, well type skylight and flat skylight. The rainproofing and drainage modes of these types of skylight are quite different. The rectangular skylight is widely used, which mainly adopts unorganized drainage at the eave head of the skylight, and the side plate of the skylight prevents the rainwater on the roof from flowing into or splashing into the room. The rectangular windproof skylight is composed of the rectangular skylight and the windproof plate arranged on both sides of the rectangular skylight, and the rainproofing facilities of the rectangular windproof skylight mainly rely on the large eave head to reduce the ventilation area of the horizontal opening, and the rainproof plate is arranged on the vertical opening or the rainproof sheet is arranged on the horizontal opening. The well type skylight is arranged on one side or both sides of the factory building, and the ventilation opening of the well type skylight is generally designed as an open type without window sash, but the well opening must be provided with rainproof facilities. The methods for the rainproof facilities include the eave head of the well opening, the rainproof sheet, the rainproof plate arranged on the vertical opening and the like. The flat skylight needs to solve the problems of radiant heat and glare caused by direct sunlight, reliable rainproofing measures, removal of condensation water in cold regions, prevention of damage caused by hail, and elimination of snow and dust. Most of the above-mentioned rainproofing methods of the existing skylight use eave head, which affects the ventilation effect, and the unorganized drainage cannot meet the needs of the industrial factory building with high waterproofing requirements, especially in the areas with many typhoons and rainwater. Therefore, it is necessary to further improve the technical scheme in the prior art to make up for the defects in the prior art.

[0003] Therefore, the Chinese patent application No. 201210324142.4 realizes effective and timely drainage by arranging the gutter at the eave head of the skylight roof, arranging the drainage opening at the bottom of the gutter and extending the overflow groove to the outside of the side sealing plate, but it cannot overcome the problem that the rainwater enters the air inlet caused by the change of the drip line caused by strong wind in the stormy weather. Therefore, the Chinese patent application No. 201610351139.X realizes the timely guidance of the rainwater to the color steel plate roof by arranging the anti-overflow plate on both sides of the light panel, folding the two side edges of the anti-overflow plate upward to be connected with the bottom of the light panel and the upper segment of the drain pipe respectively, blocking the rainwater caused by the change of the drip line caused by strong wind by means of the upwardly folded part, collecting the part of the rainwater in the anti-overflow plate, guiding the part of the rainwater to the color steel plate roof through the drain pipe, forming organized gravity drainage in the windproof plate, and effectively preventing the water leakage from the ventilating skylight into the factory building caused by the heavy rain.

[0004] By describing the structure of the existing ventilation skylight and the current main water leakage prevention technology, it is not difficult to find that the existing technology mainly focuses on the design of the structure at the ventilation opening of the ventilation skylight, such as adding a gutter, a drain pipe and an overflow groove, or further adding an overflow plate to realize the blocking and diversion of the rainwater caused by the drip line of strong wind. Obviously, it is impossible to fundamentally prevent the phenomenon of rainwater entering the factory building from the ventilation skylight or to prevent the phenomenon to the greatest extent. Therefore, when the storm weather lasts for a long time or the debris at the skylight accumulates too much and cannot be cleaned in time, the above structures for blocking and diverting rainwater will fail to fundamentally prevent the leakage phenomenon.

The special feature is that the inner end of the L-shaped overflow plate is connected below the eave opening of the light panel and is communicated with a drain pipe located below the eave opening through a perforation on the inner end panel of the L-shaped overflow plate, and the outer end of the L-shaped overflow plate is folded vertically upward and inward to form a water blocking surface which is vertically upward and has an inwardly folded top.

[0007] A plurality of transverse slide plate assemblies arranged along the longitudinal direction are arranged at the top of the wind baffle to block above the wind opening and extend to the outer edge of the wind baffle.

[0027] In order to prevent rainwater from entering during heavy rain, the embodiment is characterized in that a plurality of Figure 1 、 Figure 2 The longitudinally arranged transverse sliding plate assembly 8 is arranged above the air inlet 5 and extends to the outer edge of the wind shield 3, and can block at least two-thirds of the width of the skylight framework 2, so that the amount of rainwater entering the air inlet 5 can be greatly reduced, and the rainwater falling on the light panel 4 and the L-shaped overflow plate 6 is also greatly reduced, ensuring that the rainwater entering the drain pipe 7 is timely guided to the color steel roof without congestion or rotation, causing rainwater to accumulate for a long time and causing leakage.

[0028] As shown in Figure 2 It can be seen that the transverse sliding plate assembly 8 includes a first longitudinal beam 9 and a second longitudinal beam 10 extending along the longitudinal direction of the skylight framework 2, and a plurality of parallel transverse sliding rails 11 arranged between the first longitudinal beam 9 and the second longitudinal beam 10, wherein the first longitudinal beam 9 and the second longitudinal beam 10 are respectively fixed on the left side and the right side of the skylight framework 2. A telescopic assembly is arranged between adjacent transverse sliding rails 11, and the telescopic assembly is composed of a fixed part fixedly connected with the first longitudinal beam 9, a movable part sleeved on the fixed part, and a traction part fixed on the second longitudinal beam 10 or the color steel roof 1.

[0030] Ordinary, that is, no stormy weather, the color plate or glass plate in the telescopic assembly is at the top of the wind shield 3, the air inlet 5 is in the unshielded state, when there is a storm to cover the air inlet 5, through the connection of the steel cable end of the color plate or glass plate to the end of the second longitudinal beam 10, the winch is pulled in the forward direction, so that the color plate or glass plate moves along the transverse slide rail 11 towards the second longitudinal beam 10, realizing the shielding of the air inlet 5, and when the rain subsides, the winch is reversed, the steel cable end connected to the end of the color plate or glass plate towards the first longitudinal beam 9 is pulled by the winch, so that the color plate or glass plate returns to the original position, removing the shielding of the air inlet 5, and the first and second fixed pulleys are mainly used for limiting and guiding the direction of the corresponding steel cable, so that the whole color plate or glass plate reciprocating movement is similar to the opening and closing operation of the curtain.
