[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7 The utility model provides a technical solution: a rapid smoke exhaust device for building fire protection, comprising: a fixing plate 1 for fixing on a wall, positioning components 6 are provided on both sides of the fixing plate 1, the inner ring of the fixing plate 1 is sleeved on the outside of a smoke exhaust machine body 4, the side of the smoke exhaust machine body 4 is fixedly connected to the side of an electric push rod 3, the output shaft of the electric push rod 3 is connected to the top of a cleaning brush 5 through a connecting piece 2, and the cleaning brush 5 is located at the air inlet end of the smoke exhaust machine body 4.

[0027] The connecting member 2 includes: a connecting tube 12, the inner ring at the top of the connecting tube 12 is fixedly connected to the output shaft of the electric push rod 3, and the outside of the connecting tube 12 is provided with a fixing ring 13, a spring 14, a limit block 16 and a limit tube 15.

[0028] One side of the limit block 16 is fixedly connected to the side of the connecting tube 12, the inner ring of the fixing ring 13 is fixedly connected to the side of the connecting tube 12, the bottom of the fixing ring 13 is fixedly connected to the top of the spring 14, the bottom end of the spring 14 is fixedly connected to the top of the limit tube 15, and the inner ring of the limit tube 15 is slidably connected to the side of the connecting tube 12.

[0029] The side of the limiting tube 15 is provided with a limiting groove 17 and a transverse groove 18 , the groove wall of the limiting groove 17 is slidably connected to the outside of the limiting block 16 , the bottom of the transverse groove 18 is provided with a notch 20 , and the side of the connecting tube 12 is provided with a vertical groove 19 .

[0030] Furthermore, the groove wall of the limiting groove 17 is slidably connected to the limiting block 16 , so that the limiting cylinder 15 cannot slide up and down outside the connecting cylinder 12 .

[0031] The top of the cleaning brush 5 is fixedly connected to the bottom end of the connecting rod 9, the side of the connecting rod 9 is fixedly connected to one side of the limiting protrusion 10, the side of the connecting rod 9 is inserted into the inner ring of the connecting tube 12, and the outside of the limiting protrusion 10 is located between the horizontal slot 18 and the vertical slot 19.

[0032] Furthermore, when cleaning is completed and the cleaning brush 5 needs to be connected to the connecting piece 2, the limiting cylinder 15 is rotated by hand so that the notch 20 below the limiting cylinder 15 coincides with the vertical slot 19 of the connecting cylinder 12, and then the connecting rod 9 is inserted under the connecting cylinder 12, and the limiting protrusion 10 moves upward along the vertical slot 19 to the top of the vertical slot 19, and then the limiting cylinder 15 is released. Under the elastic force of the spring 14, the limiting cylinder 15 is reset, so that the transverse slot 18 blocks the limiting protrusion 10, so that the limiting protrusion 10 cannot move up and down, and the connecting rod 9 and the connecting cylinder 12 cannot be separated, thereby realizing the installation connection between the cleaning brush 5 and the connecting piece 2.

[0033] Furthermore, when the cleaning brush 5 needs to be cleaned, the limiting cylinder 15 can be rotated so that the notch 20 below the limiting cylinder 15 moves toward the limiting protrusion 10. When the notch 20 moves to below the limiting protrusion 10, the limiting protrusion 10 can be moved downward out of the vertical slot 19 through the notch 20, so that the connecting rod 9 can be pulled out of the connecting cylinder 12 and removed, thereby the cleaning brush 5 can be removed to facilitate cleaning of the cleaning brush 5.

[0034] A strip-shaped hole 22 is formed on one side of the fixing plate 1 , and a circular through hole 21 is formed on the other side of the fixing plate 1 . The circular through hole 21 is connected to the strip-shaped hole 22 .

[0035] Both sides of the smoke exhaust machine body 4 are fixedly connected to one side of the plug plate 7 . A positioning hole 8 is opened on the side of the plug plate 7 . The outside of the plug plate 7 is plugged into the strip hole 22 , and the positioning hole 8 is aligned with the circular through hole 21 .

[0036] Furthermore, during installation, the fixing plate 1 is fixed to the vent of the wall 27 by bolts, and then the smoke exhaust fan body 4 is inserted into the inner circle of the fixing plate 1, and the plug plates 7 on both sides of the smoke exhaust fan body 4 are inserted into the strip holes 22. Before the plug plates 7 are inserted into the strip holes 22, the pin rod 26 is first pulled out of the strip holes 22 through the circular ring at the end of the pull rod 24 to prevent the pin rod 26 from blocking the plug plates 7 from being inserted into the strip holes 22. After the plug plates 7 are inserted into the strip holes 22 and the positioning holes 8 are aligned with the circular through holes 21, the pull rod 24 can be released. At this time, the pin rod 26 is inserted into the positioning holes 8 and the circular through holes 21 under the push of the spring 25, thereby fixing the smoke exhaust fan body 4 and the fixing plate 1 together.

[0037] The positioning assembly 6 includes: a U-shaped plate 23, both ends of which are fixedly connected to the side of the fixed plate 1, the inside of the U-shaped plate 23 is slidably sleeved on the outside of the pull rod 24, one end of the pull rod 24 is provided with a circular ring and the other end is fixedly connected to the end of the pin rod 26, and the outside of the pin rod 26 is inserted into the circular through hole 21 and the positioning hole 8.

[0038] A second spring 25 is provided between the U-shaped plate 23 and the pin rod 26 , and the inner circle of the second spring 25 is sleeved on the outside of the pull rod 24 .

[0039] Furthermore, when it is necessary to dismantle and inspect, it is only necessary to pull the pull rod 24 to withdraw the pin 26 from the positioning hole 8, and the smoke exhaust machine body 4 can be removed as a whole, which is very convenient for maintenance.

[0040] Working principle: During installation, fix the fixing plate 1 to the vent of the wall 27 by bolts, then insert the smoke exhaust machine body 4 into the inner circle of the fixing plate 1, and the plug plates 7 on both sides of the smoke exhaust machine body 4 should be inserted into the strip holes 22. Before the plug plates 7 are inserted into the strip holes 22, first pull the pin 26 out of the strip holes 22 through the circular ring at the end of the pull rod 24 to prevent the pin 26 from blocking the plug plates 7 from being inserted into the strip holes 22. After the plug plates 7 are inserted into the strip holes 22 and the positioning holes 8 are aligned with the circular through holes 21, the pull rod 24 can be released. At this time, the pin 26 is inserted into the positioning holes 8 and the circular through holes 21 under the push of the spring 25. The smoke exhaust fan body 4 is fixedly connected to the fixing plate 1. When it needs to be disassembled for inspection, it is only necessary to pull the pull rod 24 to withdraw the pin 26 from the positioning hole 8, and the smoke exhaust fan body 4 can be removed as a whole, which is very convenient for maintenance; when the cleaning brush 5 needs to be cleaned, the limiting cylinder 15 can be rotated to make the notch 20 below the limiting cylinder 15 move toward the limiting protrusion 10. When the notch 20 moves to below the limiting protrusion 10, the limiting protrusion 10 can move downward out of the vertical slot 19 through the notch 20, so that the connecting rod 9 can be withdrawn from the connecting cylinder 12, so that the cleaning brush 5 can be removed, so as to facilitate the cleaning of the cleaning brush 5.
