Description

Technical Field

[0001] This utility model relates to the field of intelligent window opening technology for fire protection, specifically a smoke-triggered intelligent window opener for fire protection. Background Technology

[0002] Intelligent fire-fighting window opening is an intelligent ventilation and smoke extraction system applied in the field of building fire protection. When a fire occurs, the fire alarm system receives the fire alarm information and transmits the signal to the fire linkage control box. The fire linkage control box receives the fire signal from the original fire center of the building and transmits the signal to the electric window opener of the smoke extraction window. After receiving the fire signal, the electric window opener of the smoke extraction window automatically opens the fire smoke extraction window to achieve the purpose of ventilation and smoke extraction.

[0003] Existing window openers often make manual window opening inconvenient. For example, with electric push rod window openers, the motor and push rod are closely connected, so manual operation requires overcoming the additional resistance from the motor and transmission components. Even though some chain-type and screw-type window openers are designed with a manual priority function, seemingly allowing manual opening when powered on, in actual operation, the presence of the window opener more or less changes the original way and feel of opening the window. Compared to purely manual window opening without the opener, there are still some inconveniences. Utility Model Content

[0004] The purpose of this invention is to provide a smoke-triggered intelligent window opener for fire protection, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smoke-triggered intelligent fire-fighting window opener includes a mounting box, a mounting frame, a gear, and a connecting seat. A smoke detection sensor is provided on one side of the mounting box, and a rack is provided on one side inside the mounting frame. The mounting frame meshes with the gear, and a rotating bolt is provided at the bottom of the gear. A bottom box is provided at the bottom of the mounting box, and a window opening component is provided inside the bottom box.

[0007] The window opening assembly includes a mounting plate, a motor is installed at the bottom of the inner side of the base box, a limit groove is provided on the inner side of the mounting plate, electric telescopic rods are provided on both sides of the mounting plate, a lifting seat is provided on the electric telescopic rod, a rotating component is rotatably provided on the inner side of the lifting seat, a spring is provided on the top of the rotating component, and a hexagonal insert is provided on the top of the spring.

[0008] In a preferred embodiment of the present invention, a first connecting rod is fixedly provided on the top of the gear, and a second connecting rod is hinged to one side of the connecting seat, the second connecting rod being hinged to the first connecting rod.

[0009] In a preferred embodiment of this utility model, the mounting box is provided with limiting rails on both sides inside, and the mounting frame is provided with limiting wheels on both sides, with the limiting wheels and the limiting rails being slidably connected.

[0010] In a preferred embodiment of the present invention, a rotating groove is provided at the bottom of the inner side of the mounting box, the rotating bolt is rotatably installed in the rotating groove, and a ball bearing is provided on the side of the rotating bolt connected to the rotating groove.

[0011] In a preferred embodiment of this utility model, the bottom of the rotating bolt is provided with a hexagonal groove, and the hexagonal insert is installed and removed in the hexagonal groove.

[0012] In a preferred embodiment of this utility model, the motor drive shaft is connected to the bottom of the limiting groove, and the smoke detection sensor is electrically connected to the motor and the electric telescopic rod.

[0013] In a preferred embodiment of this utility model, a limiting rod is provided on the inner side of the bottom of the hexagonal insert, and the limiting rod is slidably connected to the inner side of the rotating part.

[0014] In a preferred embodiment of this utility model, a limiting block is provided at the bottom of the limiting rod, and the limiting block is slidably connected to the limiting groove.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: When the smoke detection sensor detects smoke, the motor and electric telescopic rod start simultaneously. The electric telescopic rod drives the lifting seat to rise, so that the hexagonal plug is on the outside of the hexagonal slot. The spring retracts, so that the hexagonal plug is in a taut state. The motor drives the limit slot to rotate, and the limit causes the top hexagonal plug to rotate at the same time, so that the hexagonal plug aligns with the hexagonal slot and is inserted. At this time, the rotation continues, thereby driving the gear to rotate, that is, automatically opening the window;

[0017] After the window is opened, the motor stops rotating due to the built-in overload protection function. Once the motor stops, the electric telescopic rod lowers the lifting seat, causing the hexagonal insert to disassemble in the hexagonal slot. This allows the window to be opened and closed manually, as the connection between the window opening assembly and the gear is directly removed. This makes manual window opening and closing unrestricted, making it easier and more convenient.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-5This utility model discloses a smoke-triggered intelligent fire-fighting window opener, comprising a mounting box 1, a mounting frame 11, a gear 12, and a connecting seat 2. The mounting box 1 and mounting frame 11 are mounting structures used for installing other structures, while the connecting seat 2 connects to the window. The mounting box 1 is installed on the outer wall of the window. The gear 12 is rotatably mounted, and the mounting frame 11 is slidably mounted. A rack 13 is provided on one side inside the mounting frame 11, meshing with the gear 12. A first connecting rod 23 is fixedly mounted on the top of the gear 12. A second connecting rod 21 is hinged on one side of the connecting seat 2, and the second connecting rod 21 is hinged to the first connecting rod 23. When the window is opened, the second connecting rod 21 and the first connecting rod 23 move, and the gear 12 rotates. Through transmission, the rack 13 and the mounting frame 11 slide. Conversely, when the gear 12 rotates, it can drive the window to open and close through transmission, similar to the effect of a door closer, and can automatically open the window. The mounting frame 11 is used to limit the rotation angle of the gear 12.

[0028] A rotating bolt 32 is provided at the bottom of the gear 12, and a rotating groove 31 is provided at the bottom of the inner side of the mounting box 1. The rotating bolt 32 is rotatably installed in the rotating groove 31. A ball bearing 33 is provided on the side where the rotating bolt 32 connects with the rotating groove 31, that is, the rotating bolt 32 and the rotating groove 31 do not directly contact each other. The rotating bolt 32 is supported by the ball bearing 33, and the gear 12 rotates smoothly by the rolling of the ball bearing 33. Limit rails 24 are provided on both sides inside the mounting box 1, and limit wheels 14 are rotatably provided on both sides of the mounting frame 11. The limit wheels 14 are slidably connected to the limit rails 24. The mounting frame 11 does not directly contact the inside of the mounting box 1, that is, the limit rails 24 limit the limit wheels 14, so that the mounting frame 11 slides stably and the limit wheels 14 rotate, thereby reducing the friction during sliding.

[0029] A smoke detection sensor 22 is installed on one side of the mounting box 1. The smoke detection sensor 22 is used to detect smoke. A base box 3 is installed at the bottom of the mounting box 1. The base box 3 is the mounting structure. A window opening assembly is installed inside the base box 3. The window opening assembly includes a mounting plate 4. The mounting plate 4 is fixedly installed. A motor 41 is installed at the bottom inside the base box 3. A limit groove 42 is provided on the inner side of the mounting plate 4 for rotation. Electric telescopic rods 44 are installed on both sides of the mounting plate 4. A lifting seat 43 is installed on the electric telescopic rod 44. A rotating part 45 is rotatably installed on the inner side of the lifting seat 43. The top of the rotating part 45 is equipped with a... A spring 52 is provided, and a hexagonal insert 53 is provided on the top of the spring 52. A hexagonal groove 34 is provided at the bottom of the rotating bolt 32. The hexagonal insert 53 is installed and removed in the hexagonal groove 34. The drive shaft of the motor 41 is connected to the bottom of the limiting groove 42. The smoke detection sensor 22 is electrically connected to the motor 41 and the electric telescopic rod 44. A limiting rod 5 is provided on the inner side of the bottom of the hexagonal insert 53. The limiting rod 5 is slidably connected to the inner side of the rotating part 45. A limiting block 51 is provided at the bottom of the limiting rod 5. The limiting block 51 is slidably connected to the limiting groove 42. The top of the limiting groove 42 is slidably connected to the limiting rod 5.

[0030] When the smoke detection sensor 22 detects smoke, the motor 41 and the electric telescopic rod 44 start simultaneously. The electric telescopic rod 44 drives the lifting seat 43 to rise, so that the hexagonal plug 53 is outside the hexagonal slot 34. At this time, the hexagonal plug 53 is not engaged with the hexagonal slot 34, but is contracted by the spring 52, so that the hexagonal plug 53 is in a taut state. The motor 41 drives the limiting groove 42 to rotate, and the top of the limiting groove 42 limits the limiting rod 5. The limiting rod 5 is stuck inside the rotating part 45, so that the top hexagonal plug 53 rotates at the same time, so that the hexagonal plug 53 engages with the hexagonal slot 34 and is inserted. At this time, it continues to rotate, thereby driving the gear 12 to rotate, that is, automatically opening the window. Conversely, when the window is open, the reverse motor 41 can be used to close the window.

[0031] The motor 41 has a built-in overcurrent protection function. When the shaft is stuck and cannot rotate, the current of the motor 41 will rise sharply. The system with overcurrent protection function will cut off the power to stop the motor 41 after detecting that the current exceeds the set threshold, so as to prevent the motor 41 from burning out due to stall. That is, when the gear 12 rotates to a certain position and the window is opened, the mounting frame 11 will be inside the mounting box 1 on one side and locked in the gear 12 by the rack 13. At this time, the motor 41 stops rotating through the built-in overcurrent protection function. After the motor 41 stops rotating, the electric telescopic rod 44 drives the lifting seat 43 to descend, so that the hexagonal plug 53 can be disassembled in the hexagonal slot 34, so that the window can be opened and closed manually.

[0032] The working principle of this utility model is as follows: When the smoke detection sensor 22 detects smoke, the motor 41 and the electric telescopic rod 44 start simultaneously. The electric telescopic rod 44 drives the lifting seat 43 to rise, so that the hexagonal insert 53 is outside the hexagonal slot 34. At this time, the hexagonal insert 53 is not engaged with the hexagonal slot 34, that is, the spring 52 retracts, so that the hexagonal insert 53 is in a taut state. The motor 41 drives the limiting groove 42 to rotate, and the top of the limiting groove 42 limits the limiting rod 5. The limiting rod 5 is stuck inside the rotating part 45, so that the top hexagonal insert... When 53 rotates simultaneously, the hexagonal insert 53 aligns with the hexagonal slot 34 and is inserted. The rotation continues, driving the gear 12 to rotate, thus automatically opening the window. After opening, the motor 41 stops rotating due to its built-in overload protection. Once the motor 41 stops, the electric telescopic rod 44 lowers the lifting seat 43, disassembling the hexagonal insert 53 in the hexagonal slot 34. This allows for manual opening and closing of the window, directly disconnecting the window opening assembly from the gear 12. This eliminates restrictions on manual window opening and closing, making it easier and more convenient.
