Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust window technology, specifically a quick-opening electric smoke exhaust window device. Background Technology

[0002] Smoke exhaust windows are an important component of building smoke control systems. They are mainly used to exhaust indoor smoke in emergencies such as fires to ensure the safe evacuation of personnel and facilitate fire rescue operations.

[0003] Currently, natural smoke exhaust windows in tall spaces use manual and centralized control opening methods. For non-tall spaces, only manual opening devices are required. However, common manual opening devices are inconvenient to operate and slow to open, which cannot meet the current needs.

[0004] Therefore, a rapid electric smoke exhaust window opening device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fast electric smoke exhaust window opening device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention starts the motor via a controller, which drives the gear to rotate. Since the gear and rack are meshed, the rotation of the gear uses the rack to move the second smoke window, thereby opening the second smoke window. Compared with existing designs, the second smoke window in this invention opens automatically, eliminating the need for manual operation. It is convenient to operate, opens quickly, and meets current needs. The fixing bar can be manually rotated, and at the same time, the spring will stretch accordingly.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example 1:

[0030] Please see Figure 1-3 This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: a fast electric smoke exhaust window opening device, comprising: a smoke exhaust window frame 1; a first smoke exhaust window 2 and a second smoke exhaust window 4 are provided inside the smoke exhaust window frame 1; wherein the first smoke exhaust window 2 is fixedly installed inside the smoke exhaust window frame 1, and the second smoke exhaust window 4 is movably installed inside the smoke exhaust window frame 1 via guide rails 3 at the bottom and top of the smoke exhaust window frame 1; an embedding groove 6 is provided at the front end of the smoke exhaust window frame 1, and a motor 7 is embedded in the embedding groove 6. A gear 8 is fixed to the output end of the motor 7; a rack 9 that meshes with the gear 8 is fixed to the front end of the second smoke window 4; a controller 10 is installed at the bottom of the motor 7; a connecting block 11 is fixed to the front end of the smoke window frame 1, and a connecting groove 12 is opened at the front end of the connecting block 11. A connecting strip 14 is connected in the connecting groove 12, and a smoke sensor 13 is installed at the front end of the connecting strip 14. The smoke sensor 13 is electrically connected to the controller 10, and the controller 10 is electrically connected to the motor 7. A sealing strip 5 is installed at the rear end of the second smoke window 4. The sealing strip 5 is made of silicone material.

[0031] Specifically, this invention starts the motor 7 via the controller 10, which drives the gear 8 to rotate. Since the gear 8 meshes with the rack 9, the rotation of the gear 8 will drive the second row of smoke windows 4 to move using the rack 9, thereby achieving the purpose of opening the second row of smoke windows 4. In addition, a smoke sensor 13 is provided. When the smoke sensor 13 detects smoke, it sends a signal to the controller 10, which then starts the motor 7, which in turn drives the second row of smoke windows 4 to move, thus achieving the purpose of opening the second row of smoke windows 4. Compared with the existing inventions, this invention adopts two methods of opening the second row of smoke windows 4, combining automatic and manual opening, with more complete functions. It does not require manual operation, is easy to operate, and has a faster opening speed, which can meet the current needs.

[0032] Because a sealing strip 5 is installed at the rear end of the second row of smoke windows 4, the sealing strip 5 can improve the sealing performance at the overlap of the first row of smoke windows 2 and the second row of smoke windows 4.

[0033] Example 2:

[0034] Please see Figure 1 , 3 4. This utility model provides a technical solution: a fast electric smoke exhaust window opening device, wherein a support bar 15 is fixed to the top of the connecting bar 14, a horizontal bar 16 is fixed to the rear end of the support bar 15, a slot 17 is provided on the top of the horizontal bar 16, a first concave block 18 is fixed to the top of the connecting block 11, a fixing bar 20 is movably connected to the inside of the first concave block 18 through a first movable pin 19, the second concave block 21 is fixed to the top of the connecting block 11, a second movable pin 22 is movably connected to the inside of the second concave block 21, a third concave block 23 is fixed to the outer wall of the fixing bar 20, a third movable pin 24 is movably connected to the inside of the third concave block 23, and a spring 25 is provided between the second movable pin 22 and the third movable pin 24, the two ends of the spring 25 being respectively connected to the second movable pin 22 and the third movable pin 24.

[0035] Specifically, since the fixing strip 20 is movably connected to the inside of the first concave block 18 through the first movable pin 19, the fixing strip 20 can be manually driven to rotate. At the same time, the spring 25 will also perform corresponding stretching movements. The spring 25 will also move accordingly within the second concave block 21 and the third concave block 23 using the second movable pin 22 and the third movable pin 24. After one end of the fixing strip 20 is disengaged from the slot 17, the connecting strip 14 can be pulled out from the connecting groove 12 of the connecting block 11, and the smoke sensor 13 (model QLSS015R) can be disassembled. Therefore, this utility model is convenient for disassembling and maintaining the smoke sensor 13 and has high practicality.

[0036] Working principle:

[0037] When smoke extraction is needed, the operator can use the controller 10 to start the motor 7 embedded in the slot 6. The motor 7 will drive the gear 8 to rotate. Since the gear 8 and the rack 9 are meshed, the rotation of the gear 8 will drive the second smoke window 4 to move in conjunction with the guide rail 3 inside the smoke window frame 1, thereby opening the second smoke window 4. Furthermore, a smoke sensor 13 is installed. When the smoke sensor 13 detects smoke, it sends a signal to the controller 10. The controller 10 then starts the motor 7, which in turn drives the second smoke window 4 to move, similarly opening the second smoke window 4. A sealing strip 5 is installed at the rear end of the smoke window 4. The sealing strip 5 can improve the sealing performance at the overlapping part of the first row of smoke windows 2 and the second row of smoke windows 4. Since the fixing strip 20 is movably connected to the inside of the first concave block 18 through the first movable pin 19, the operator can manually drive the fixing strip 20 to rotate. At the same time, the spring 25 will also perform corresponding stretching movements. The spring 25 will also move accordingly within the second concave block 21 and the third concave block 23 using the second movable pin 22 and the third movable pin 24. After one end of the fixing strip 20 is disengaged from the slot 17, the connecting strip 14 can be pulled out from the connecting groove 12 of the connecting block 11, and the smoke sensor 13 can be disassembled.
