Detailed Description

The present invention will be described in detail with reference to the following embodiments.

This waterproof heat preservation exhaust apparatus in roof, the exhaust core pipe adopts the venturi principle, under the effect that outside wind flows, can furthest in time take out the inside steam of roof heat preservation, arrange to the atmosphere, simultaneously under the effect of blast pipe fin, through the bearing motion of installing on the blast pipe top, can keep the direction of exhaust core pipe, the direction of the incoming wind is faced all the time, furthest utilizes the pressure that the flow of wind produced, partly big air vent is reserved to the core bottom of exhausting again, also help the steam in the heat preservation in time to derive, the effect of shielding of exhaust core honeycomb duct simultaneously, avoid the direct short circuit of outside air to be discharged by exhaust core pipe, also leave a lot of little air vents bottom the blast pipe, can in time guide into the blast pipe with the steam in the heat preservation, derive steam by the exhaust core.

As shown in fig. 1-2, a roof waterproof heat preservation exhaust device, an exhaust pipe 1 of the device is coaxially provided with an exhaust core 2, vent holes are arranged on the exhaust pipe 1 and the exhaust core 2, one end of the exhaust core 2 is connected with an exhaust core draft tube 3, the other end of the exhaust core 2 is connected with a connecting tube 4-2 of the exhaust core 4, as shown in fig. 5, the exhaust core 4 is a pipeline which contracts firstly and then expands gradually, a throat 4-1 of the pipeline is provided with a connecting tube 4-2 structure, namely a venturi tube structure, as shown in fig. 5, the end of the exhaust core 4 which contracts firstly is an inlet channel, as shown in fig. 5, a left end, as shown in fig. 5, the end which expands gradually is an outlet channel, as shown in fig. 5, and the middle of the inlet channel and the outlet channel is the throat 4-1. When external wind enters the exhaust core pipe 4, the airflow is thinned from rough to quicken the gas flow rate, so that the gas forms a negative pressure in the exhaust core pipe 4, and the water vapor under the waterproof layer is pumped out. The end part of one side (outlet channel) of the exhaust core pipe 4 which is gradually enlarged is fixedly connected with an exhaust pipe tail fin 5.

The length of the exhaust pipe 1 and the exhaust core 2 is determined according to the thickness of the roof heat-insulating layer, and the diameters of the exhaust pipe 1 and the exhaust core are generally standard pipes. The diameter of the exhaust core 2 is smaller than that of the exhaust pipe 1 so as to facilitate the circulation of water vapor, and the diameter of the exhaust core 2 is generally 1/5-1/2 of the diameter of the exhaust pipe 1.

As shown in fig. 2-4, the exhaust pipe 1 and the bottom of the exhaust core 2 (the bottom is the lower part shown in fig. 2) are provided with a plurality of rows of small vent holes 9, and the upper end of the exhaust pipe 1 (the upper end is the upper part shown in fig. 2) is provided with one or more rows of large vent holes 10, in this embodiment, a row of large vent holes 10. Little air vent 9 and big air vent 10 can in time lead the leading-in blast pipe 1 of steam in the heat preservation, increase flow area, derive steam by exhaust core 2. The small vent holes 9 at the bottoms of the exhaust pipe 1 and the exhaust core 2 are used for circulating water vapor in the deep part of the insulating layer, so that the situation that the circulation of residual water vapor at the upper end of the exhaust pipe 1 is influenced by the large water vapor flow at the nearby part (the bottom of the exhaust pipe 1) is avoided, and the bottom is made into the small vent holes 9; the upper end of the exhaust pipe 1 is far away from the small vent hole 9 of the exhaust core 2, so that a large vent hole 10 is formed, and the circulation of residual water vapor at the upper end of the exhaust pipe 1 is facilitated. Thereby more thoroughly discharging the water vapor in the heat-insulating layer.

As shown in fig. 1, 2 and 8, one end of the exhaust core 2, which is not provided with the small vent hole 9, is connected with the exhaust core pipe 4 through an exhaust core pipe seat 6, the exhaust core pipe seat 6 is of a circular structure, an outer annular wall 6-1 of the exhaust core pipe seat 6 is clamped at the end part of the exhaust pipe 1, one end of an inner annular wall 6-2 of the exhaust core pipe seat 6 is sleeved with the exhaust core 2, and the other end of the inner annular wall is connected with a connecting pipe 4-2 of the exhaust core pipe 4 through a bearing 7.

A sealing ring 8 is arranged in the exhaust core tube seat 6. The joint of the connecting pipe 4-2 of the exhaust core pipe 4 and the exhaust core 2 is ensured to be airtight, and the effect of exhausting internal water vapor is influenced.

As shown in fig. 6, the exhaust core draft tube 3 is a funnel-shaped structure, the neck 3-1 of the exhaust core draft tube 3 is fixed at the bottom of the exhaust core 2, and the end surface of the bucket 3-2 of the exhaust core draft tube 3 and the end surface of the exhaust core 2 are on the same horizontal plane. The exhaust core draft tube 3 has a shielding effect, and external air is prevented from being directly discharged from the exhaust core tube in a short circuit mode.

As shown in FIG. 7, one end of a connecting rod 5-2 of the exhaust pipe tail fin 5 is fixed on a flange 5-1, the flange 5-1 is fixedly connected with the end part of the exhaust core pipe 4, and the other end of the connecting rod 5-2 is fixed with a tail wing plate 5-3. The tail wing plates 5-3 are blown by wind to drive the exhaust core pipe 4 to rotate, so that the direction of the exhaust core pipe 4 always faces the direction of the incoming wind, and the pressure generated by the flow of the wind is utilized to the maximum extent.

The exhaust core 2, the exhaust core pipe 4 and the exhaust core pipe seat 6 are installed on site and are fixed by sealing glue. The new building can be installed, and even the built building roof can be reformed at a later stage. The roof floor is perforated on site, the device is inserted into the hole, directly contacts the floor, and is fixed through local waterproof treatment of the roof at the later stage. When wind blows the tail wing plates 5-3, the exhaust core pipe 4 is connected with the exhaust core pipe seat 6 through the bearing 7, so that an inlet channel of the exhaust core pipe 4 faces the direction of the incoming wind, the pressure generated by the flow of the wind is utilized to the maximum extent, and at the moment, water vapor in the heat-insulating layer enters the exhaust core flow guide pipe 3 through the small vent hole 9 and the large vent hole 10 of the exhaust pipe 1 and then enters the exhaust core 2 to be taken away by the wind in the exhaust core pipe 4, so that the purpose of discharging the water vapor under the waterproof layer is achieved.
