Description

Technical Field

[0001] The utility model relates to the technical field of ventilation skylights, in particular to a roof ventilation skylight. Background Art

[0002] Skylights provide daylight and ventilation. There are many types of skylights in modern buildings. According to their structure, location and relationship with the roof, they can be summarized into three types: zenith type, convex type and concave type.

[0003] Due to the large flow of people and the density of people at the railway station, if the railway station is not ventilated for a long time, it is easy to produce odor and reduce air circulation, making the air quality worse and breeding bacteria. Passengers waiting in the station who inhale stagnant air for a long time are prone to adverse symptoms.

[0004] Therefore, it is necessary to install ventilation skylights in the railway station. However, due to the large building of the railway station and the large flow of people, the need for ventilation is relatively large. However, the current ventilation windows can only supply natural wind. When the natural wind is weak, the ventilation effect will be reduced. Therefore, how to provide a roof ventilation skylight with good ventilation effect is particularly important. In view of this, we propose a roof ventilation skylight. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a roof ventilation skylight to solve the technical problem of low ventilation effect when the current wind force is relatively low.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a roof ventilation skylight, including a window with a hole in the middle, a transmission mechanism is arranged on one side of the window, and a ventilation structure is placed at the lower end of the window;

[0007] The ventilation structure includes a connecting rod fixedly connected to the window body, the connecting rod is shaped as a double right-angle rod symmetrically bent at 90 degrees along the axis, the bottom end of the connecting rod is fixedly connected to a shaft sleeve, a plurality of blades A are arranged on the surface of the shaft sleeve, the blades A are installed at an inclined angle on the surface of the shaft sleeve, the root of the blade A is twisted compared to the tail of the blade A, and the blade A is bulging in the middle and gradually shrinking toward both sides of the root and the tail;

[0008] The interior of the shaft sleeve is divided into a plurality of cavities by arranging a partition plate, a plurality of through grooves are opened on the surface of the partition plate, and vertical rods are fixedly arranged in the through grooves.

[0009] Preferably, a rotating shaft is rotatably connected at the center of the surface of the vertical rod, and blades B are fixedly connected to two symmetrical sides of the outer side of the rotating shaft, and the blades B are arranged in a rectangular shape with four right-angled sides.

[0010] Preferably, a through hole is opened on the surface of the sleeve, and the position of the through hole is staggered with the blade A.

[0011] Preferably, a window is slidably connected to the window body, and one end of the window passes through the side wall of the window body and is fixedly connected to a fixing block.

[0012] Preferably, the transmission mechanism comprises a forward and reverse motor, which is fixedly placed on the side wall of the window, the output end of the forward and reverse motor is fixedly connected to a transmission wheel A, and one end of the window is fixedly connected to a transmission wheel B.

[0013] Preferably, the surfaces of the transmission wheel A and the transmission wheel B are simultaneously transmission-connected with a conveyor belt, and one end of the fixed block is fixedly connected to the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This device sets up a ventilation structure. When the wind enters the station room through the window, it is perpendicular to blade A, which can drive blade A to rotate to the greatest extent. The rotating blade A can also cut and push the wind to accelerate the circulation of the wind. By setting a cavity, blade B can come into contact with the wind, and the wind in the cavity is passed to the surface of blade A. At the same time, the airflow convected through the torsion part of blade A is converged, so that the airflow blown downward by blade A is more concentrated, thereby increasing the wind force of natural wind, improving wind efficiency, and accelerating air circulation in the station.

[0016] 2. By setting up a transmission mechanism, the conveyor belt can be driven left and right by the operation of the forward and reverse motor according to the weather, thereby realizing the control of the window opening and closing, avoiding the failure to close the window in time on rainy days, causing rainwater to enter the room, and facilitating the use of the skylight.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Example: A roof ventilation skylight, see Figures 1 to 4 , comprising a window 1 with a hole in the middle, a transmission mechanism 2 is arranged on one side of the window 1, and a ventilation structure 3 is placed at the lower end of the window 1;

[0024] The ventilation structure 3 includes a connecting rod 301 fixedly connected to the window 1. The shape of the connecting rod 301 is set as a double right-angle rod symmetrically bent at 90 degrees on the axis. The bottom end of the connecting rod 301 is fixedly connected to a shaft sleeve 302. The surface of the shaft sleeve 302 is provided with a plurality of blades A303. The blades A303 are installed at an inclined angle on the surface of the shaft sleeve 302. The root of the blade A303 is twisted compared to the tail of the blade A303. The blade A303 is bulging in the middle and gradually shrinking toward the root and the tail. By setting the blade A303, the blade end of the blade A303 can cut the airflow when the blade A303 is running, and push it downward, so that the air supply surface can be more comprehensive and uniform.

[0025] The interior of the shaft sleeve 302 is divided into a plurality of cavities by means of partitions 304 . A plurality of through grooves are formed on the surface of the partitions 304 . Vertical rods 305 are fixedly disposed in the through grooves.

[0026] Specifically, a rotating shaft 306 is rotatably connected at the center of the surface of the vertical rod 305, and blades B307 are symmetrically fixedly connected to the outer sides of the rotating shaft 306. The blades B307 are arranged in a rectangular shape with four right-angled sides. A through hole is opened on the surface of the sleeve 302, and the position of the through hole is staggered with the blade A303, so that the inner circle wind in the cavity can be pushed by the blade B307 and mixed with the airflow on the surface of the through-hole sleeve 302, thereby increasing the air volume and air outlet area of ​​the natural wind, and accelerating the circulation of indoor air.

[0027] Furthermore, a window 101 is slidably connected inside the window body 1 , and one end of the window 101 passes through the side wall of the window body 1 and is fixedly connected to a fixing block.

[0028] Furthermore, the transmission mechanism 2 includes a forward and reverse motor 201, which is fixedly placed on the side wall of the window 1, and the output end of the forward and reverse motor 201 is fixedly connected to a transmission wheel A202, and one end of the window 1 is fixedly connected to a transmission wheel B203. It is characterized in that the surfaces of the transmission wheels A202 and B203 are simultaneously transmission-connected to a conveyor belt 204, and one end of the fixed block is fixedly connected to the conveyor belt 204. Through the conveyor belt 204, the window 101 can be driven to translate when the conveyor belt 204 is driven, so as to control the position of the window 101, facilitate opening and closing the window according to weather conditions, and improve the flexibility of using the skylight.

[0029] Working principle: When the device is used, the forward and reverse motor 201 can be started under the condition that the weather is not bad. The forward and reverse motor 201 drives the transmission wheel A202 to rotate, and drives the conveyor belt 204 to rotate through the transmission wheel A202 and the transmission wheel B203, so that the window 101 follows the fixed block to move in the window body 1, so as to realize the automatic opening and closing of the window 101. When the window 101 is opened to ventilate the room, when the wind enters the room vertically through the window body 1, the blade A303 is in direct contact with the wind, so that the blade A303 rotates, cuts and pushes the wind, and can contact the wind over a large area through the cavity, and drive the blade B307 to rotate the rod through the wind, so that the wind is transported to the surface of the sleeve 302 through the through hole and contacts with the blade A303, thereby increasing the rotation rate of the blade A303, and can transport the wind faster and increase the wind speed.
