Description

Technical Field

[0001] This invention relates to a powerful smoke exhaust fire damper operator for fire protection systems. Background Technology

[0002] The existing smoke exhaust and fire prevention regulating valve operating mechanism uses a manual reset with a built-in handle, which is laborious, inefficient, and subject to many environmental limitations, requiring operation from height. Summary of the Invention

[0003] This invention provides a powerful smoke exhaust fire damper operator, characterized in that: the upper end of the telescopic locking operating rod 1 is rotatably connected to one end of the middle operating rod 2, with a rotation shaft of 12; the other end of the middle operating rod 2 is rotatably connected to one end of the short arm rod 3, with a rotation shaft of 23; the other end of the short arm rod 3 is rotatably connected to the operating turntable 4, with a rotation shaft of 34; a suitable position on the middle operating rod 2 is rotatably connected to one end of the long arm rod 5, with a rotation shaft of 25; the other end of the long arm rod 5 is rotatably connected to the operating turntable 4, with a rotation shaft of 45; and two or more locking posts 6 are installed on the operating turntable 4, perpendicular to the plane of the operating turntable 4 and surrounding the center of the operating turntable 4. Using the above structure, when operating the handle 81 of the smoke exhaust fire damper's operating mechanism 8, a powerful smoke exhaust fire damper operator first uses a stationary operating turntable 4 in its naturally drooping state, causing the locking pin 6 on the operating turntable 4 to lock the handle 81 of the smoke exhaust fire damper's operating mechanism 8. Then, the retractable locking operating rod 1 is pulled downwards. Through the combined action of the middle operating rod 2, short arm rod 3, and long arm rod 5, the operating turntable 4 is rotated. When the operating turntable 4 rotates, the locking pin 6 locks and drives the handle 81 of the smoke exhaust fire damper's operating mechanism 8 to rotate and reset. Since the rotation angle of the operating turntable 4 is greater than the rotation angle required for the handle 81 of the smoke exhaust fire damper's operating mechanism 8 to reset, the vertical downward operation of the retractable locking operating rod 1 is transformed into a rotation operation of the operating turntable 4, making it easy to reset the smoke exhaust fire damper.

[0004] The middle operating lever 2 has a first rotation adjustment hole 231 and a second rotation adjustment hole 251; the short arm lever 3 has a third rotation adjustment hole 321 and a fourth rotation adjustment hole 341; and the long arm lever 5 has a fifth rotation adjustment hole 521 and a sixth rotation adjustment hole 541. The first rotation adjustment hole 231, the second rotation adjustment hole 251, the third rotation adjustment hole 321, the fourth rotation adjustment hole 341, the fifth rotation adjustment hole 521, and the sixth rotation adjustment hole 541 are used for fine-tuning the initial position and rotation position of the operating turntable 4, so that the operating turntable 4 can be in the optimal state during operation.

[0005] The operating turntable 4 has an operating visual hole 7, which makes it easy for the operator to determine the position of the operating turntable 4 aligned with the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper in front of it.

[0006] This invention enables convenient, labor-saving, and space-saving resetting of smoke exhaust and fire prevention regulating valves during routine inspections or after a fire.

[0007] Figure 2 The diagram shows the operational connection of this invention.

[0008] Figure 3 The diagram shows the operation of the present invention after vertical pulling. Detailed Implementation Example

[0009] See Figure 1 , Figure 2 , Figure 3 The upper end of the retractable locking operating lever 1 is rotatably connected to one end of the middle operating lever 2, with a rotation axis of 12. The other end of the middle operating lever 2 is rotatably connected to one end of the short arm lever 3, with a rotation axis of 23. The other end of the short arm lever 3 is rotatably connected to the operating turntable 4, with a rotation axis of 34. At a suitable position on the middle operating lever 2, it is rotatably connected to one end of the long arm lever 5, with a rotation axis of 25. The other end of the long arm lever 5 is rotatably connected to the operating turntable 4, with a rotation axis of 45. On the operating turntable 4, perpendicular to the plane of the operating turntable 4, two or more locking posts 6 are installed around the center of the operating turntable 4. With the above structure, when operating the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper, a powerful smoke exhaust fire damper operator is first used to operate the turntable 4 in its natural downward state when it is stationary, so that the locking posts 6 on the operating turntable 4 lock the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper. Figure 2 Then, pull down the retractable locking operating lever 1. The middle operating lever 2, short arm lever 3, and long arm lever 5 work together to rotate the operating turntable 4. When the operating turntable 4 rotates, the locking pin 6 locks and drives the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper to rotate and reset. Figure 3 Since the rotatable angle of the operating turntable 4 is greater than the rotation angle required for the reset of the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper, the vertical downward operation of the telescopic locking operating rod 1 is transformed into the rotation operation of the operating turntable 4, and the reset of the smoke exhaust fire damper can be easily completed.

[0010] In actual operation, the first rotation adjustment hole 231, the second rotation adjustment hole 251, the third rotation adjustment hole 321, the fourth rotation adjustment hole 341, the fifth rotation adjustment hole 521 and the sixth rotation adjustment hole 541 can be used to fine-tune the initial position and rotation position of the operating turntable 4, so that the operating turntable 4 is in the best state during operation.

[0011] The operator can easily determine the position of the handle 81 of the operating mechanism 8 of the smoke exhaust fire damper by using the operation viewing hole 7 on the operating turntable 4.

[0012] The telescopic locking operating lever 1 is made of aluminum alloy, with three telescopic sections, allowing for an operating height of up to 5 meters. The operating turntable 4 is made of aluminum alloy. The locking post 6, rotating shaft 12, rotating shaft 23, rotating shaft 25, rotating shaft 34, and rotating shaft 45 are made of steel.
