Description

Technical Field

[0001] This utility model relates to the field of safety device technology, and more specifically, to a safety device applied in a chemical plant. Background Technology

[0002] Chemical plant production processes are complex, involving numerous chemical reactions, and the chemicals handled are often flammable, explosive, toxic, and highly corrosive. In the event of a safety accident, not only will it pose a serious threat to the lives of personnel within the plant, leading to numerous casualties, but it will also cause severe pollution to the surrounding environment, incalculable damage to the ecosystem, and enormous economic losses to the enterprise.

[0003] A search revealed Chinese patent application number 202421080417.9, which discloses a safety warning and isolation device for chemical safety. The device includes a fiberglass fence composed of horizontal bars, vertical posts, mounting grooves, and positioning holes, and a snap-fit ​​assembly. The snap-fit ​​assembly connects and fixes the horizontal bars to the vertical posts. The assembly includes a snap-fit ​​unit and a blocking unit. The snap-fit ​​unit engages with the positioning holes to connect and fix the horizontal bars to the vertical posts. The blocking unit blocks the snap-fit ​​unit, allowing the positioning holes on the outside of the vertical posts to pass smoothly through the snap-fit ​​unit, facilitating the sequential passage of the vertical posts through multiple horizontal bars. This invention, through the snap-fit ​​assembly, enables convenient installation of the vertical posts and horizontal bars. Compared to rivet fixing, installation is faster. The snap-fit ​​assembly is made entirely of corrosion-resistant plastic, effectively preventing the fiberglass fence from suffering damage due to rust caused by rivets, thus better adapting to the production environment of chemical plants. However, the aforementioned patents have the following shortcomings: they lack corresponding warning structures, their functions are relatively limited, and the latching components are installed inside the crossbar, so it is not immediately apparent if an S-shaped spring is damaged or fails to engage properly. Therefore, this utility model proposes a new solution. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figures 1-7As shown, this embodiment proposes a safety device for use in a chemical plant, including a bracket 3. A fence is installed on the top of the bracket 3. The fence includes multiple horizontal bars 1 and multiple vertical poles 2 with circular cross-sections. The horizontal bars 1 have mounting grooves 8 that mate with the vertical poles 2. A mounting seat 7 is detachably installed on the top of the horizontal bars 1, located outside the mounting grooves 8. Two S-shaped spring pieces 10 are symmetrically installed on the mounting seat 7. Locking protrusions 11 are fixedly connected to the inner walls of the S-shaped spring pieces 10. Positioning holes 9 that mate with the locking protrusions 11 are provided on the vertical poles 2. Through the installation of the mounting seat 7, the S-shaped spring pieces 10 can be exposed outside the horizontal bars 1 during use. If a certain S-shaped spring piece... The system allows for timely detection and handling of any damage to the spring clip 10 or its failure to engage properly. The detachable mounting base 7 on the top of the crossbar 1 facilitates easy replacement of the S-shaped spring clip 10 if it is damaged. During use, the upright 2 is inserted into the mounting groove 8 on the crossbar 1, causing the outer wall of the groove 8 to push open the locking protrusion 11 and the S-shaped spring clip 10. After inserting the upright 2 into the last crossbar 1, rotating the upright 2 aligns the positioning hole 9 with the locking protrusion 11 to lock the upright 2. The entire installation process is simpler and more convenient, requiring no complex structural assistance. It also includes a warning mechanism mounted on the top of the upright 2, which includes... The alarm light 4 and reflective strip 5 installed on the top of the pole 2 are removed. A distance monitoring mechanism 6 that works in conjunction with the alarm light 4 is installed on the front of the bracket 3. Through the setting of the alarm light 4, reflective strip 5 and distance monitoring mechanism 6, the reflective strip 5 can enhance the visibility of the fence by reflecting light at night or in low light conditions, preventing personnel from accidentally bumping into or entering the dangerous area. At the same time, the distance monitoring mechanism 6 can monitor the distance between personnel or equipment and the fence in real time. When the target is close to the fence, the alarm light 4 will be activated to sound an alarm, preventing personnel or equipment from approaching the dangerous area inside the chemical plant. A first anti-tilting mechanism 12 and a second anti-tilting mechanism are symmetrically installed at the bottom of the bracket 3. 13. A telescopic support mechanism is installed on the back of the fence, which cooperates with the first anti-tilting mechanism 12 and the second anti-tilting mechanism 13. With the first anti-tilting mechanism 12, the second anti-tilting mechanism 13 and the telescopic support mechanism, the first anti-tilting mechanism 12 and the second anti-tilting mechanism 13 can prevent the device from tipping over when it is hit by external force, effectively improving the overall anti-tipping ability of the device. With the telescopic support mechanism, it can cooperate with the first anti-tilting mechanism 12 and the second anti-tilting mechanism 13 to further improve the stability of the device. At the same time, its degree can be flexibly adjusted according to the ground conditions, thereby ensuring the overall support effect.

[0031] like Figures 1-3As shown, in a preferred embodiment, based on the above method, the support 3 further includes a frame 301, with a base plate 302 fixedly connected to the bottom end of the frame 301. Two first support frames 303 are symmetrically installed on the top of the frame 301, and a second support frame 304 is provided between the two first support frames 303. Screw holes are provided at all four corners of the base plate 302. Grooves for installing the crossbar 1 are provided on both the first support frames 303 and the second support frames 304. A first through groove 305 for installing the distance monitoring mechanism 6 is provided on the frame 301. It should be noted that the arrangement of the frame 301, the base plate 302, the first support frames 303 and the second support frames 304 facilitates the support and fixation of the fence. The first through groove 305 facilitates the installation of the distance monitoring mechanism 6. The groove facilitates the installation of the crossbar 1 in the first support frames 303 and the second support frames 304.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the distance monitoring mechanism 6 further includes a housing 601 movably installed inside the first through slot 305. A distance sensor 603 is installed inside the housing 601, and a connecting plate 602 is fixedly installed on the outer wall of the housing 601. First bolts 604 are threaded to the four corners of the connecting plate 602. It should be noted that during use, the housing 601 can be installed on the frame 301 via the connecting plate 602 and the first bolts 604. The housing 601 facilitates the installation of the distance sensor 603, enabling the monitoring of the distance between objects or people and the fence.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the mounting base 7 further includes a first base 701 and a second base 702 symmetrically arranged. Both the first base 701 and the second base 702 have a second through groove 704 that mates with the S-shaped spring piece 10. Both the first base 701 and the second base 702 are threadedly connected with a second bolt 703. The top of the crossbar 1 has a screw hole that mates with the second bolt 703, located outside the mounting groove 8. It should be noted that during use, the first base 701 and the second base 702 can easily install an S-shaped spring piece 10. When an S-shaped spring piece 10 is damaged, the corresponding first base 701 and the second base 702 can be disassembled for replacement, effectively reducing maintenance costs. The second bolt 703 and the screw hole facilitate the installation and disassembly of the first base 701 and the second base 702 during use.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the telescopic support mechanism further includes a sleeve 14, with an adjusting rod 16 threadedly connected to the sleeve 14 inside. An anti-slip foot 15 is hinged to the bottom end of the sleeve 14, and the top end of the adjusting rod 16 is rotatably connected to the fence via a hinge seat. It should be noted that during use, rotating the adjusting rod 16 allows adjustment of its extension degree inside the sleeve 14, thereby adjusting the overall length of the telescopic support mechanism. The anti-slip foot 15 increases friction with the ground, improving the stability of the support.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in a preferred embodiment, based on the above method, both the first anti-tilt mechanism 12 and the second anti-tilt mechanism 13 include a mounting sleeve 121 fixedly connected to the bottom end of the base plate 302. The mounting sleeve 121 is internally threaded with a mounting head 123. Three evenly distributed anti-tilt rods 124 are rotatably mounted on the bottom of the mounting head 123. An anti-slip sleeve 125 is installed on the end of the anti-tilt rod 124 away from the mounting head 123. A limiting block 122 that cooperates with the anti-tilt rod 124 is fixedly connected to the bottom of the mounting sleeve 121. A groove 17 for accommodating the anti-tilt rod 124 is opened at the bottom of the base plate 302. The top of the inner wall of the groove 17 is threaded to cooperate with the mounting head 123. It should be noted that the groove 17 allows for easy storage of the folded first anti-tilt mechanism 12 and the second anti-tilt mechanism 13. When stored inside the groove 17, the mounting head 123 can be fixed by the thread on the top of the inner wall of the groove 17, thus preventing the first anti-tilt mechanism 12 and the second anti-tilt mechanism 13 from sliding out of the groove 17. In use, the mounting head 123 can be screwed into the mounting sleeve 121 through 124 to fix the mounting head 123. Then, the three anti-tilt rods 124 can be rotated and opened to complete the installation of the device. The anti-slip sleeve 125 increases the friction between the anti-tilt rods 124 and the ground.

[0036] Specifically, the working principle of this safety device applied to the chemical plant is as follows: When in use, insert the upright 2 into the mounting groove 8 on the horizontal bar 1, so that the outer wall of the mounting groove 8 pushes open the locking protrusion 11 and the S-shaped spring 10. After the upright 2 is inserted into the last horizontal bar 1, rotate the upright 2 so that the positioning hole 9 is aligned with the locking protrusion 11 to complete the locking of the upright 2. When in use, the reflective strip 5 can enhance the visibility of the fence by reflecting light at night or in low light environment, preventing personnel from accidentally bumping into or entering the dangerous area. At the same time, the distance monitoring mechanism 6 can monitor the distance between personnel or equipment and the fence in real time. When the target is close to the fence, the alarm light 4 will be activated to sound an alarm, preventing personnel or equipment from approaching the dangerous area in the chemical plant.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
