[0023] The utility model provides a technical solution: Figure 1-Figure 5 As shown, in this embodiment, a gas leakage detection device for chemical production safety includes a first sealing frame 1, a gas detector probe 18 is fixedly installed on the top of the inner side of the first sealing frame 1, an alarm light 3 is fixedly installed on the top of the first sealing frame 1, a first through groove 24 is opened on one side of the first sealing frame 1, the first through groove 24 runs through the first sealing frame 1, both sides of the first sealing frame 1 are slidably connected with a clamping block 10, a clamping assembly is provided on the top of the first sealing frame 1, and the clamping assembly is used to drive the two clamping blocks 10 to move, a U-shaped plate 4 is fixedly connected to the top of the first sealing frame 1, a bracket 5 is fixedly connected to one side of the U-shaped plate 4, and a second sealing frame 2 is slidably connected to one side of the bracket 5. A lifting assembly is provided at the bottom of the frame 5, which is used to drive the second sealing frame 2 to move. A second through groove 25 is provided on one side of the second sealing frame 2, and the second through groove 25 passes through the second sealing frame 2.

A first fitting groove 22 is provided inside the two clamping blocks 10, and a second fitting groove 23 is provided inside the two pads 11. A first lining block 12 is fixedly connected between the inner walls of the two first fitting grooves 22, and a second lining block 13 is fixedly connected between the inner walls of the two second fitting grooves 23. Both the first lining block 12 and the second lining block 13 are made of rubber.

[0024] When the gas leakage detection device is tested, the first sealing frame 1 is first placed on the outside of the chemical pipeline connection position, and then the second sealing frame 2 is driven by the lifting component to move on one side of the bracket 5 on the side of the U-shaped plate 4, so that the first sealing frame 1 contacts the second sealing frame 2, so that the pipeline connection is located between the inner walls of the first sealing frame 1 and the second sealing frame 2, so that the pipeline contacts the inner sides of the first through groove 24 and the second through groove 25, and then the two holding blocks 10 are driven by the clamping component to move on both sides of the first sealing frame 1 respectively, so that the two holding blocks 10 are respectively in contact with the two pads 11, so that the detection device is fixed on the chemical pipeline to avoid displacement during detection. At the same time, through the action of the first lining blocks 12 in the two first fitting grooves 22 and the second lining blocks 13 in the two second fitting grooves 23, the friction of the two holding blocks 10 is enhanced and the wear on the pipeline during installation is reduced. Then, through the gas detector probe 18 (specific model is Dräger X-am The 2500 gas detector probe 18 detects the pipeline connection position. If a leak occurs, it will send a signal through the alarm light 3, making it easier for staff to carry out corresponding inspection and maintenance of the chemical pipeline. Therefore, the gas leak detection device further improves the safety of chemical pipelines during use and the accuracy of gas leak detection.

[0025] like Figure 1-Figure 5 As shown, the clamping assembly includes a clamping threaded rod 7, which is rotatably connected between the U-shaped plate 4 and the first sealing frame 1, and the outer side of the clamping threaded rod 7 is threadedly connected to the displacement plate 6, and the bottom of the displacement plate 6 is fixedly connected to the outer sides of the two clamping blocks 10. The top of the U-shaped plate 4 is rotatably connected to the rotating block 8, and the bottom end of the rotating block 8 extends to the interior of the U-shaped plate 4 and is fixedly connected to the clamping threaded rod 7, and the outer side of the rotating block 8 is fixedly connected to the fixing rod 9.

[0026] By manually rotating the fixing rod 9, the rotating block 8 drives the clamping threaded rod 7 to rotate between the top of the inner side of the U-shaped plate 4 and the top of the first sealing frame 1, so that the displacement plate 6 drives the two clamping blocks 10 to move on both sides of the first sealing frame 1 respectively, further improving the stability of the detection device during detection.

[0027] like Figure 1-Figure 5As shown, the lifting assembly includes a guide groove 19, and a guide block 21 is slidably connected between the inner walls of the guide groove 19, one side of the guide block 21 is fixedly connected to the limit plate 20, and one side of the limit plate 20 is slidably connected to the bracket 5, and the side of the guide block 21 away from the limit plate 20 is fixedly connected to the second sealing frame 2, and the bottom of the second sealing frame 2 is rotatably connected to the lifting threaded rod 15, and the outer side of the lifting threaded rod 15 is threadedly connected to the mounting plate 14, one side of the mounting plate 14 is fixedly connected to the bracket 5, and the bottom of the mounting plate 14 is rotatably connected to the turntable 16, one end of the turntable 16 passes through the mounting plate 14 and is fixedly connected to the lifting threaded rod 15, and one side of the turntable 16 is fixedly connected to the handle 17.

[0028] By manually rotating the handle 17, the turntable 16 drives the lifting threaded rod 15 to rotate at the bottom of the second sealing frame 2. Since the lifting threaded rod 15 is threadedly connected to the mounting plate 14, when the lifting threaded rod 15 rotates, the second sealing frame 2 moves with the assistance of the guide groove 19, the guide block 21 and the limit plate 20. Therefore, through the movement of the second sealing frame 2, the gas leakage detection device can be quickly set on the outside of the chemical pipeline connection position, which facilitates the use of the detection device.

[0029] The utility model provides a gas leakage detection device for chemical production safety, and the specific working principle is as follows: when the gas leakage detection device is used for detection, the first sealing frame 1 is first placed on the outside of the chemical pipeline connection position, and then the handle 17 is manually rotated, so that the turntable 16 drives the lifting threaded rod 15 to rotate at the bottom of the second sealing frame 2. Since the lifting threaded rod 15 is threadedly connected to the mounting plate 14, when the lifting threaded rod 15 rotates, the second sealing frame 2 moves with the assistance of the guide groove 19, the guide block 21 and the limit plate 20, so that the first sealing frame 1 contacts the second sealing frame 2, so that the pipeline connection position is located between the inner walls of the first sealing frame 1 and the second sealing frame 2. At this time, the outer side of the pipeline is respectively aligned with the inner sides of the first through groove 24 and the second through groove 25. Contact, and then manually rotate the fixing rod 9, so that the rotating block 8 drives the clamping threaded rod 7 to rotate between the top of the inner side of the U-shaped plate 4 and the top of the first sealing frame 1, so that the displacement plate 6 drives the two clamping blocks 10 to move on both sides of the first sealing frame 1, respectively, so that the two clamping blocks 10 are in contact with the two pads 11 respectively, so that the detection device is fixed on the chemical pipeline to avoid displacement during detection. At the same time, through the action of the first lining blocks 12 inside the two first fitting grooves 22 and the second lining blocks 13 inside the two second fitting grooves 23, the friction force of the two clamping blocks 10 is enhanced and the wear on the pipeline during installation is reduced. Then the gas detector probe 18 starts to work, so that it performs corresponding leakage detection on the pipeline connection position. If a leak occurs, a signal will be sent through the alarm light 3.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
