Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a building ventilation structure. Background Art

[0002] Building ventilation refers to ensuring the circulation and quality of air inside a building through proper design and installation of ventilation systems, thereby providing a comfortable indoor environment. Good building ventilation can effectively remove indoor pollutants, moisture and odors, provide fresh air, and regulate indoor temperature and humidity, thereby ensuring comfort, health and safety inside the building.

[0003] The existing building ventilation structure is to install exhaust fans in the ventilation duct system, and exhaust the dirty air in different rooms through the exhaust fans through multiple ventilation ducts. When a fire occurs in a single space, the single ventilation duct cannot be controlled, resulting in dispersed wind force and low exhaust efficiency.

[0004] Therefore, it is necessary to design a building ventilation structure that can exhaust the air in the room where the fire occurs, improve the exhaust efficiency, reduce the spread of the fire, and improve the operability of the rescue personnel. Utility Model Content

[0005] In order to overcome the shortcomings of existing building ventilation structures, in which a single ventilation duct cannot be controlled when a fire occurs in a single space, resulting in dispersed wind force and low exhaust efficiency, the utility model provides a building ventilation structure that can discharge the air in the room where the fire occurs, improve the exhaust efficiency, reduce the spread of fire, and improve the operability of rescue personnel.

[0006] The technical solution of the utility model is: a building ventilation structure, comprising a first ventilation pipe, a diversion pipe and a second ventilation pipe, the rear side of the first ventilation pipe is connected to the diversion pipe, and the rear side of the diversion pipe is connected to a plurality of second ventilation pipes.

[0007] Furthermore, a filter screen is included, and the front part of the first ventilation pipe is connected with the filter screen.

[0008] Furthermore, it also includes a connecting ring, a connecting rod and a mounting seat. The front and rear parts of the second ventilation pipe are connected to the connecting ring, the upper side of the connecting ring is connected to the connecting rod, and the upper side of the connecting rod is connected to the mounting seat.

[0009] Furthermore, mounting holes are provided on both the left and right parts of the upper side of the mounting seat.

[0010] Furthermore, it also includes a connecting seat, a support frame, a servo motor, a flat belt and a rotating disk. The connecting seat is connected between the second ventilation ducts, and three support frames are connected to the lower middle side of the connecting seat. The support frames are all connected to servo motors. A flat belt is wrapped around the output shaft of the servo motor and the adjacent second ventilation duct through a pulley. The front pulley is connected to a rotating disk, and the rotating disk is located inside the second ventilation duct.

[0011] Furthermore, the diameter of the rotating disk is the same as the inner diameter of the adjacent second ventilation pipe.

[0012] The beneficial effects are as follows: 1. The utility model starts the servo motor in the room where no fire has occurred, drives the pulley to rotate, causes the flat belt to rotate, and then drives the rotating disk to rotate, and then starts the exhaust fan, thereby achieving the effect of being able to exhaust the air in the room where the fire has occurred, improving the exhaust efficiency, reducing the spread of fire, and improving the operability of rescue personnel.

[0013] 2. The utility model installs the mounting base on the connecting rod on the wall by passing bolts through the mounting holes, thereby achieving the effect of fixing the second ventilation duct, reducing the shaking of the second ventilation duct during operation, and increasing the stability of the second ventilation duct.

DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings.

[0019] A building ventilation structure, such as Figure 1-Figure 3As shown, it includes a first ventilation pipe 1, a shunt pipe 2 and a second ventilation pipe 3, and also includes a filter 101. The front part of the first ventilation pipe 1 is connected to the filter 101 for filtering dust. The rear side of the first ventilation pipe 1 is connected to the shunt pipe 2, and the rear side of the shunt pipe 2 is connected to three second ventilation pipes 3. It also includes a connecting ring 4, a connecting rod 5 and a mounting seat 6. The front and rear parts of the second ventilation pipe 3 are connected to the connecting ring 4, the upper side of the connecting ring 4 is connected to the connecting rod 5, and the upper side of the connecting rod 5 is connected to the mounting seat 6. The left and right parts of the upper side of the mounting seat 6 are provided with mounting holes for convenience. For installation, it also includes a connecting seat 7, a support frame 8, a servo motor 9, a flat belt 10 and a rotating disk 11. The connecting seat 7 is connected between the second ventilation pipes 3, and three support frames 8 are connected to the lower middle side of the connecting seat 7. The support frames 8 are all connected to the servo motors 9. The flat belt 10 is wound around the output shaft of the servo motor 9 and the adjacent second ventilation pipe 3 through a pulley. The rotating disk 11 is connected to the front pulley. The diameter of the rotating disk 11 is the same as the inner diameter of the adjacent second ventilation pipe 3, and the rotating disk 11 is located inside the second ventilation pipe 3.

[0020] When using the device, firstly, the mounting base 6 on the connecting rod 5 is installed on the wall by passing the bolts through the mounting holes, so that the second ventilation pipe 3 can be fixed, the shaking of the second ventilation pipe 3 during operation is reduced, and the stability of the second ventilation pipe 3 is increased. After the installation is completed, the remaining ventilation pipes are installed in different rooms through the second ventilation pipe 3 on the diversion pipe 2, and then the exhaust fan is installed on the first ventilation pipe 1, and then the exhaust fan is started. When the exhaust fan operates, the dirty air in the room is discharged from the first ventilation pipe 1 through the second ventilation pipe 3, and the filter 101 is used to filter the dust. When a fire occurs in a single room and the fire has spread and When the fire is large, the servo motor 9 in the room where the fire has not occurred can be started, and the servo motor 9 on the support frame 8 can be operated to drive the rear pulley to rotate, so that the flat belt 10 rotates, drives the front pulley to rotate, and then drives the rotating disk 11 to rotate. At this time, the second ventilation duct 3 in the room where the fire has occurred is in an open state, and the remaining second ventilation ducts 3 are in a closed state. Then the exhaust fan is started and the exhaust fan operates, so that the wind force of the exhaust fan is concentrated on the second ventilation duct 3 in the room where the fire has occurred, so that the air in the room where the fire has occurred can be discharged, the exhaust efficiency is improved, the spread of fire is reduced, and the operability of rescue personnel is improved.
