Specific implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0018] Please refer to Figures 1-5 , a fire alarm device for the safety of office buildings in fire protection engineering based on an Internet platform, including a fire alarm box 100, a smoke sensor 200 is assembled on the outer side of the fire alarm box 100, a controller 300 is assembled inside the fire alarm box 100, a servo motor 400 is assembled inside the fire alarm box 100, and the bottom of the servo motor 400 is drivingly connected to a rotating rod 500; Inside the fire alarm box 100, there is an alarm component 600. The alarm component 600 includes a first hydraulic chamber 601 and a second hydraulic chamber 602. The first hydraulic chamber 601 is assembled outside the rotating rod 500. When the smoke sensor 200 detects smoke, the servo motor 400 can be started through the controller 300, so that the servo motor 400 drives the rotating rod 500 connected to it in a clockwise rotation. The rotating rod 500 drives the first hydraulic chamber 601 assembled outside it to rotate rapidly. Inside the first hydraulic chamber 601, a sliding block 604 is slidably connected through an elastic telescopic plate 603. When the first hydraulic chamber 601 rotates rapidly, the sliding block 604 inside the first hydraulic chamber 601 slides inside the first hydraulic chamber 601 by stretching the elastic telescopic plate 603 under the action of centrifugal force, so that the pressure inside the first hydraulic chamber 601 increases. An arc-shaped push rod 605 is slidably connected to the side of the first hydraulic chamber 601. When the pressure inside the first hydraulic chamber 601 increases, it can drive the arc-shaped push rod 605 slidably connected to the first hydraulic chamber 601 to move. One end of the second hydraulic chamber 602 is slidably connected to an arc-shaped force-bearing rod 606. The arc-shaped force-bearing rod 606 is located on the side of the arc-shaped push rod 605 and is in contact with the arc-shaped push rod 605. The other end of the second hydraulic chamber 602 is slidably connected to a buzzer 607. Inside the second hydraulic chamber 602, a baffle 608 is rotatably connected. On the side of the baffle 608, two elastic telescopic rods 609 are assembled. The two elastic telescopic rods 609 are symmetrically distributed with respect to the baffle 608. When the arc-shaped push rod 605 presses the arc-shaped force-bearing rod 606, the arc-shaped force-bearing rod 606 moves into the second hydraulic chamber 602, so that the pressure inside the second hydraulic chamber 602 increases, driving the buzzer 607 slidably connected to the second hydraulic chamber 602 to move, so that the buzzer 607 moves out of the fire alarm box 100 and performs corresponding alarm operations, improving the alarm effect when the device is in use.

[0019] During use, when the smoke sensor 200 detects smoke, the servo motor 400 can be started through the controller 300, so that the servo motor 400 drives the rotating rod 500 connected to it in a clockwise rotation. The rotating rod 500 drives the first hydraulic chamber 601 assembled outside it to rotate rapidly. The sliding block 604 inside the first hydraulic chamber 601 slides inside the first hydraulic chamber 601 by stretching the elastic telescopic plate 603 under the action of centrifugal force, so that the pressure inside the first hydraulic chamber 601 increases, driving the arc-shaped push rod 605 slidably connected to the first hydraulic chamber 601 to move, so that the arc-shaped push rod 605 presses the arc-shaped force-bearing rod 606. The arc-shaped force-bearing rod 606 moves into the second hydraulic chamber 602 under the action of the arc-shaped push rod 605, so that the pressure inside the second hydraulic chamber 602 increases, driving the buzzer 607 slidably connected to the second hydraulic chamber 602 to move, so that the buzzer 607 moves out of the fire alarm box 100 and performs corresponding alarm operations. Embodiment 2

[0020] See also Figures 1-7 On the basis of the first embodiment, a cleaning assembly 700 is arranged on the outer side of the fire alarm box 100. The cleaning assembly 700 includes a fixed plate 701. The fixed plate 701 is internally rotatably connected with a transmission rod 702 that penetrates through it. The outer side of the rotating rod 500 is equipped with a sprocket wheel 1 703. When the rotating rod 500 rotates clockwise, the sprocket wheel 1 703 assembled on the outer side thereof can be driven to rotate clockwise. The outer side of the sprocket wheel 1 703 is equipped with a chain 704. The outer side of the transmission rod 702 is fixedly connected with a sprocket wheel 2 705. The chain 704 is far from one end of the sprocket wheel 1 703 and is assembled at the outer side of the sprocket wheel 2 705. When the sprocket wheel 1 703 rotates clockwise, the chain 704 assembled on the outer side of the sprocket wheel 1 703 is matched, so that the sprocket wheel 2 705 connected to the sprocket wheel 1 703 through the chain 704 synchronously rotates clockwise, and the sprocket wheel 2 705 drives the transmission rod 702 fixedly connected thereto to rotate. The top of the transmission rod 702 is fixedly connected to a bevel gear 1 706, and only half of the teeth are arranged on the outer side of the bevel gear 1 706. When the transmission rod 702 rotates, the transmission rod 702 drives the bevel gear 1 706 fixedly connected thereto to rotate clockwise. The side of the buzzer 607 is rotatably connected to a torsion spring rod 707, and the side of the torsion spring rod 707 is fixedly connected to a bevel gear 2 708, and the bottom of the torsion spring rod 707 is fixedly connected to a cleaning brush 709. When the buzzer 607 is moved out of the fire alarm box 100, the bevel gear 2 708 mounted thereon moves to the side position of the bevel gear 1 706. At this time, the bevel gear 1 706 drives the meshing bevel gear 2 708 to rotate counterclockwise, and the bevel gear 2 708 drives the torsion spring rod 707 fixedly connected thereto to rotate counterclockwise. Because the outer side of the bevel gear 1 706 is only provided with half of the teeth, when the end of the bevel gear 1 706 without teeth rotates to the bevel gear 2 708, the bevel gear 2 708 loses its restriction, and the torsion spring rod 707 connected to the bevel gear 2 708 loses its restriction, and then rotates in the opposite direction under its own action to reset. In this way, the torsion spring rod 707 can reciprocate, driving the cleaning brush 709 fixedly connected thereto to reciprocate on the surface of the buzzer 607, thereby cleaning the buzzer 607 to a certain extent, thereby preventing the dust generated by the fire from clogging the buzzer 607 when the alarm operation is performed, thereby further improving the alarm effect when the device is used.

[0021] When in use, on the basis of the first embodiment, when the rotating rod 500 rotates clockwise, the sprocket wheel 1 703 mounted on the outside thereof can be driven to rotate clockwise, and the chain 704 mounted on the outside of the sprocket wheel 1 703 can be matched to make the sprocket wheel 2 705 connected to the sprocket wheel 1 703 through the chain 704 to rotate clockwise synchronously, and the sprocket wheel 2 705 drives the transmission rod 702 fixedly connected thereto to rotate, so that the transmission rod 702 drives the bevel gear 1 706 fixedly connected thereto to rotate clockwise; and when the buzzer 607 is moved out of the fire alarm box 100, the bevel gear 2 708 mounted thereon moves to the side position of the bevel gear 1 706. At this time, the bevel gear 1 70 6 drives the meshing bevel gear 2 708 to rotate counterclockwise, and the bevel gear 2 708 drives the torsion spring rod 707 fixedly connected thereto to rotate counterclockwise. Because the outer side of the bevel gear 1 706 is only provided with half of the teeth, when the end of the bevel gear 1 706 without the teeth rotates to the bevel gear 2 708, the bevel gear 2 708 loses its restriction, and the torsion spring rod 707 connected to the bevel gear 2 708 loses its restriction, and then rotates in the opposite direction under its own action to reset. In this way, the torsion spring rod 707 can reciprocate, driving the cleaning brush 709 fixedly connected thereto to reciprocate on the surface of the buzzer 607, thereby cleaning the buzzer 607 to a certain extent. Embodiment 3

[0022] See also Figures 1-8, based on the first and second embodiments, a protection component 800 is provided on the outer side of the fire alarm box 100. The protection component 800 includes a third hydraulic chamber 801, and a connecting rod 802 is slidably connected to the side surface of the third hydraulic chamber 801. When the arc-shaped force-bearing rod 606 moves into the second hydraulic chamber 602, causing the pressure in the second hydraulic chamber 602 to increase, since a baffle 608 is rotatably connected inside the second hydraulic chamber 602, and an elastic telescopic rod 609 is assembled on the side surface of the baffle 608, the force in the second hydraulic chamber 602 is preferentially conducted into the third hydraulic chamber 801 communicated with it, causing the pressure in the third hydraulic chamber 801 to increase, driving the connecting rod 802 slidably connected to the third hydraulic chamber 801 to move preferentially. A protection cover plate 803 is fixedly connected to the side surface of the connecting rod 802. There are four protection cover plates 803, and the four protection cover plates 803 are circumferentially arranged in a column around the fire alarm box 100. When the connecting rod 802 moves preferentially, the connecting rod 802 drives the protection cover plate 803 fixedly connected to it to move, thereby preferentially opening the opening on the side of the fire alarm box 100; subsequently, the arc-shaped force-bearing rod 606 continues to move. Under the action of the pressure in the second hydraulic chamber 602, the baffle 608 squeezes the elastic telescopic rod 609 to generate rotation, and at this time, the buzzer 607 can be driven to move. The device preferentially opens the opening on the side of the fire alarm box 100, and then moves out the buzzer 607. The setting of the protection cover plate 803 further improves the dust-proof effect of the device on the buzzer 607 in the unactivated state.

[0023] During use, based on the first and second embodiments, when the arc-shaped force-bearing rod 606 moves into the second hydraulic chamber 602, causing the pressure in the second hydraulic chamber 602 to increase, since a baffle 608 is rotatably connected inside the second hydraulic chamber 602, and an elastic telescopic rod 609 is assembled on the side surface of the baffle 608, the force in the second hydraulic chamber 602 is preferentially conducted into the third hydraulic chamber 801 communicated with it, causing the pressure in the third hydraulic chamber 801 to increase, driving the connecting rod 802 slidably connected to the third hydraulic chamber 801 to move preferentially, and the connecting rod 802 drives the protection cover plate 803 fixedly connected to it to move, thereby preferentially opening the opening on the side of the fire alarm box 100; subsequently, the arc-shaped force-bearing rod 606 continues to move. Under the action of the pressure in the second hydraulic chamber 602, the baffle 608 squeezes the elastic telescopic rod 609 to generate rotation, and at this time, the buzzer 607 can be driven to move.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
