Technical Field

[0001] The utility model relates to the technical field of poison gas monitoring, in particular to a poison gas monitoring and alarm device for a factory building. Background Art

[0002] When activated catalysts are produced, some toxic gases will be produced. In order to prevent gas leakage from causing safety accidents, a toxic gas monitoring and alarm device is used to detect them. Since some toxic gases have a lower density than air, they will float in the air, while some toxic gases have a higher density than air and will sink to the bottom of the air. Since the existing toxic gas monitoring and alarm devices are all installed at a fixed height, they cannot monitor and alarm the toxic gases in a timely manner during detection, which can easily cause safety accidents.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1: Reference Figure 1-5 A factory building toxic gas monitoring and alarm device includes a fixing frame 7, which has a plurality of fixing holes. The fixing frame 7 is mounted on the wall of the factory building by using bolts to match the fixing holes.

[0021] The fixing frame 7 is fixedly connected to the motor 2, which is a self-locking motor. When the motor 2 stops, the motor 2 can support the harmful gas detection alarm 3.

[0022] The output shaft of the motor 2 is connected to a rotating shaft 6, a pull rope 1 is connected to the pull rope 1, a harmful gas detection alarm 3 is connected to the harmful gas detection alarm 3, a T-shaped slider 5 is connected to the harmful gas detection alarm 3 through a connecting mechanism, a T-shaped slide rail 4 is fixedly connected to the fixed frame 7, the T-shaped slider 5 and the T-shaped slide rail 4 ensure the stability of the harmful gas detection alarm 3 during movement, and a T-shaped slider 5 is slidably provided on the T-shaped slide rail 4. The motor 2 rotates forward, driving the rotating shaft 6 to rotate, so that the rotating shaft 6 is wound around the pull rope 1, driving the harmful gas detection alarm 3 to rise in height. When the motor 2 reverses and the pull rope 1 is loosened, the harmful gas detection alarm 3 is lowered in height. When there is toxic gas, an alarm can be issued in time to prevent the occurrence of dangerous accidents.

[0023] Example 2: Reference Figure 1-4 As another preferred embodiment of the present invention, on the basis of embodiment 1, the connecting mechanism includes a fixing plate 10, which is fixedly connected to the harmful gas detection alarm 3. Connecting prisms 11 are provided on both sides of the fixing plate 10, and connecting sleeves 9 are fixedly connected on both sides of the T-shaped slider 5. The two connecting prisms 11 are respectively inserted into the connecting sleeves 9. The two connecting prisms 11 are limited by a limiting mechanism. By separating the connecting column 11 from the connecting sleeve 9, the fixing plate 10 can be separated from the T-shaped slider 5, the harmful gas detection alarm 3 can be disassembled, and the harmful gas detection alarm 3 can be maintained.

[0024] The limiting mechanism includes a limiting groove 13, which is opened on the connecting prism 11. A stopper 12 is connected to the fixed plate 10 by a pin shaft. The stopper 12 is located in the limiting groove 13. The stopper 12 acts as a limit block on the connecting prism 11, thereby preventing the connecting prism 11 from detaching from the connecting sleeve 9.

[0025] During use: the motor 2 rotates forward, driving the rotating shaft 6 to rotate, so that the rotating shaft 6 wraps around the pull rope 1, driving the harmful gas detection alarm 3 to rise in height; when the motor 2 reverses and loosens the pull rope 1, the harmful gas detection alarm 3 drops in height, so that the harmful gas detection alarm 3 moves up and down for detection; when the harmful gas detection alarm 3 needs to be disassembled, rotate the block 12 to disengage the block 12 from the limiting groove 13, pull the connecting prism 11, separate the connecting column 11 from the connecting sleeve 9, separate the fixing plate 10 from the T-shaped slider 5, and disassemble the harmful gas detection alarm 3.

[0026] Example 3: Reference Figure 5As another preferred embodiment of the present invention, based on Example 1, the stopper 12 is made of iron material, and a magnet is fixedly connected to the limiting groove 13. Through the attraction between the magnet and the stopper 12, the stopper 12 plays a limiting role, preventing the stopper 12 from escaping from the limiting groove 13.

[0027] A winding reel 8 is fixedly connected to the rotating shaft 6. The winding reel 8 is used to wind or loosen the wires connected to the harmful gas detection alarm 3 as the height of the harmful gas detection alarm 3 increases, thereby arranging the wires.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
