Description

Technical Field

[0001] This utility model belongs to the field of chemical safety management, and in particular relates to an alarm device for chemical safety management. Background Technology

[0002] Alarm devices for chemical safety management are core equipment for ensuring production safety, enabling early risk warnings through real-time monitoring of environmental parameters. Their core technologies include three main modules: multi-sensor fusion, intelligent algorithm analysis, and tiered alarm linkage. Functionally, they offer three-dimensional protection capabilities: first, an audible and visual alarm system with a 105-decibel buzzer and 360° visible warning lights; second, support for dual-mode output, allowing integration with a DCS control system; and third, a wireless transmission module supporting multi-level push notifications via WeChat / SMS. Typical application scenarios include reactor pressure monitoring, pipeline leak detection, and gas monitoring in tank areas.

[0003] Comparing with Chinese Patent CN215068569U, an alarm device for chemical safety management is disclosed, including a fixed plate. Two symmetrical mounting blocks are fixedly connected to the lower surface of the fixed plate. Fixed insert plates are inserted into the surfaces of the two mounting blocks. A detection box is fixedly connected to the lower surface of the fixed insert plates. An alarm controller is fixedly installed on the inner wall of the detection box. An audible and visual alarm is installed on the lower surface of the detection box. A motor is fixedly installed on the lower surface of the alarm controller. A first bevel gear is fixedly connected to the output shaft of the motor, and a connecting plate is fixedly connected to the lower surface of the alarm controller. By setting up the detection box and detection hole, when a gas leak occurs at the site, the gas can be detected through the detection hole, and the audible and visual alarm will be activated in real time. By setting up a brush and a cleaning tank, when the detection hole is blocked by dust and particles, it can be cleaned in time without manual operation, ensuring that the alarm device remains in an effective working state at all times.

[0004] However, the aforementioned patent requires manually pulling the movable rods on both sides and disassembling and reassembling the wires for maintenance and replacement, which is time-consuming and laborious. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an alarm device for chemical safety management to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An alarm device for chemical safety management includes a main component for detection and alarm, and a base component for wall mounting. A housing component for supporting, fixing, and protecting the interior is magnetically mounted on the base component. The main component is mounted at the end of the housing component. The base component includes a base plate with four mounting holes evenly distributed at its four corners. A limiting connection mechanism is provided on the bottom surface of the base plate, with two magnets symmetrically mounted on the bottom surface of the limiting connection mechanism. An electrical connection mechanism for elastically compressing and connecting a circuit is installed in the middle of the base plate. The housing component includes a housing shell with several ventilation windows evenly distributed around its circumference. A plug-in mechanism is provided on the top surface of the housing shell, with two iron plates and two fixed electrodes symmetrically arranged on the plug-in mechanism. The fixed electrodes are electrically connected to the main component.

[0008] Furthermore: the main component includes a box cover plate, on which a plurality of buckles are evenly distributed; an alarm controller is installed on the same side of the box cover plate and the buckles, and an audible and visual alarm is installed on the opposite side of the box cover plate and the buckles.

[0009] Furthermore: the limiting connection mechanism includes a limiting boss provided on the bottom surface of the base plate, and positioning posts are symmetrically arranged in front and behind the limiting boss; the electrical connection mechanism includes two movable electrodes symmetrically arranged inside the limiting boss, a spring plate is provided on the movable electrode, a fixing plug is provided on the spring plate, and a wire clamping bolt is installed on the top of the fixing plug.

[0010] Furthermore: the top surface of the base plate is provided with a clearance groove, one side of the clearance groove is provided with a wire passage groove, and the electrical connection mechanism is disposed in the clearance groove.

[0011] Furthermore: the insertion mechanism includes a limiting groove provided in the middle of the top surface of the housing, and positioning grooves symmetrically provided on the front and back of the top surface of the housing.

[0012] Furthermore, the positioning groove is a U-shaped groove.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] 1. The magnetic attraction between the base assembly's magnet and the housing assembly's iron sheet, combined with the guiding structure of the limiting boss and positioning post, enables "one-click" fixing and disassembly of the housing. During maintenance, the housing can be separated without tools, simplifying the cleaning and parts replacement process.

[0015] 2. While magnetically securing the electrodes, the fixed and movable electrodes automatically press against each other, ensuring continuous power supply and avoiding misalignment or loosening issues caused by traditional wiring. The electrical connection mechanism uses a spring-loaded design to push the movable electrode, maintaining tight contact even after long-term use and reducing the risk of poor contact.

[0016] 3. The electrical connection mechanism is pre-installed on the base plate, requiring only one wiring during installation. Subsequent replacement of the enclosure does not require rewiring, saving labor costs. The modular design of the alarm controller, audible and visual alarm, etc., means that only the corresponding parts need to be replaced when there is partial damage, reducing maintenance costs.

A housing component for supporting, fixing and protecting the interior is magnetically mounted on the base component, and the main component is installed at the end of the housing component.

[0027] In this embodiment: the base assembly includes a base plate 301, with four mounting holes 302 evenly distributed at its four corners. A limiting connection mechanism is provided on the bottom surface of the base plate 301, and two magnets 311 are symmetrically mounted on the bottom surface of the limiting connection mechanism. An electrical connection mechanism for elastically compressing and connecting the circuit is installed in the middle of the base plate 301. The limiting connection mechanism includes a limiting boss 303 provided on the bottom surface of the base plate 301, and positioning posts 304 are symmetrically arranged at the front and rear of the limiting boss 303. The electrical connection mechanism includes two movable electrodes 310 symmetrically arranged inside the limiting boss 303. A spring plate 309 is provided on the movable electrode 310, and a fixing plug 307 is provided on the spring plate 309. A wire clamping bolt 308 is installed on the top of the fixing plug 307. A clearance groove 305 is provided on the top surface of the base plate 301, and a wire passage groove 30 is provided on one side of the clearance groove 305. 6. The electrical connection mechanism is set in the clearance groove 305. During installation, first tighten the two wire clamping bolts 308 respectively, press the positive and negative poles of the wires onto the fixing plugs 307 in the clearance groove 305 respectively, and then pass the wires through the wire through groove 306 to pass the wires through the base plate 301. Then fix the base plate 301 to the wall with bolts to complete the installation of the base plate 301. Align the limiting groove 203 with and insert it into the limiting boss 303 on the bottom surface of the base plate 301. At the same time, insert the positioning post 304 into the positioning groove 204 to ensure that the magnet 311 corresponds to the iron piece 206 and form a magnetic attraction force to fix the housing 201 to the base plate 301. The fixed electrode 205 on the housing 201 presses the movable electrode 310 on the base plate 301. The fixing plug 307 pushes the movable electrode 310 to the fixed electrode 205 to conduct electricity through the elastic force of the spring plate 309.

[0028] In this embodiment: the enclosure assembly includes an enclosure 201, with several ventilation windows 202 evenly distributed around its circumference. An insertion mechanism is provided on the top surface of the enclosure 201, with two iron plates 206 and two fixed electrodes 205 symmetrically arranged on the insertion mechanism. The fixed electrodes 205 are electrically connected to the main body assembly. The insertion mechanism includes a limiting groove 203 in the middle of the top surface of the enclosure 201 and positioning grooves 204 symmetrically arranged on the front and back of the top surface of the enclosure 201. The positioning grooves 204 are U-shaped. The limiting groove 203 on the top surface of the enclosure 201 is aligned with and inserted into the limiting boss 303 on the bottom surface of the base plate 301, while the positioning post 304 is inserted into the positioning groove 204. The iron plates 206 are used to attract and fix the magnet 311, and the fixed electrodes 205 are used to contact and press the movable electrode 310 to supply power to the alarm controller 103 and the audible and visual alarm 104.

[0029] In this embodiment: the main component includes a box cover plate 101, on which a plurality of buckles 102 are evenly distributed. An alarm controller 103 is installed on the same side of the box cover plate 101 and the buckles 102, and an audible and visual alarm 104 is installed on the opposite side of the box cover plate 101 and the buckles 102. A gas detection head is provided on the alarm controller 103. The box cover plate 101 is fixed to one end of the box housing 201 by the buckles 102, so that the alarm controller 103 is inserted into the box housing 201, while the audible and visual alarm 104 is left outside. The fixed electrode 205 ensures the power supply to the alarm controller 103 and the audible and visual alarm 104. During operation, air enters and exits the box housing 201 through the ventilation window 202. When the gas detection head on the alarm controller 103 detects a gas leak, the audible and visual alarm 104 is activated to sound an alarm.

[0030] Working principle: During installation, first tighten the two wire clamping bolts 308 respectively, pressing the positive and negative terminals of the wire onto the fixing plugs 307 in the clearance groove 305. Then, pass the wire through the wire through the wire groove 306 to pass the base plate 301. Next, fix the base plate 301 to the wall with bolts to complete the installation of the base plate 301. Then, fix the box cover plate 101 to one end of the box housing 201 with the buckle 102, so that the alarm controller 103 is inserted into the box housing 201, while the audible and visual alarm 104 remains outside. Finally, close the limiting groove on the top surface of the box housing 201. Align and insert the limiting boss 303 on the bottom surface of the base plate 301, and at the same time insert the positioning post 304 into the positioning groove 204 to ensure that the magnet 311 corresponds to the iron piece 206 and forms a magnetic attraction force to fix the box shell 201 to the base plate 301. The fixed electrode 205 on the box shell 201 presses against the movable electrode 310 on the base plate 301. The fixed plug 307 pushes the movable electrode 310 to be in close contact with the fixed electrode 205 through the elastic force of the spring plate 309 to conduct electricity, ensuring the power supply of the alarm controller 103 and the sound and light alarm 104.

[0031] During disassembly and maintenance, reverse the steps described above to plug and unplug the housing 201 to repair or replace the alarm controller 103 and the audible and visual alarm 104, as well as clean the dust on the ventilation window 202.

[0032] During operation, air enters and exits the housing 201 through the ventilation window 202. When the gas detection head on the alarm controller 103 detects a gas leak, the audible and visual alarm 104 is activated to sound an alarm.

[0033] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
