Description
Technical Field
[0001] The utility model relates to the technical field of alarm instruments, in particular to an explosion-proof alarm instrument. Background Art
[0002] An alarm is a device used to prevent or mitigate the consequences of an incident. It is divided into mechanical alarms and electronic alarms.
[0003] The inventors believe that the aforementioned related technologies suffer from the following drawbacks: Chemical plants produce large quantities of flammable and toxic gases during production. If flammable gas leaks during production and workers fail to detect them immediately, fires or explosions can easily occur. Existing alarms are unable to withstand the impact of the explosion and are subsequently damaged. Consequently, they are unable to monitor the surrounding environment and determine whether toxic gas leaks have occurred due to the impact of the explosion. Consequently, rescue workers are unable to immediately understand the situation inside the chemical plant through the alarms, making it impossible to formulate a detailed rescue plan, thus delaying the optimal rescue time. Utility Model Content
[0004] In order to solve the above problems, the utility model provides an explosion-proof alarm device.
[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: an explosion-proof alarm instrument, including a handle, the upper end of the handle is fixedly provided with an external thread, the upper end of the handle is installed with a threaded sleeve, the inner wall of the threaded sleeve is provided with an internal thread, the external thread is threadedly connected to the internal thread, the upper surface of the threaded sleeve is fixedly provided with an alarm instrument body, the two opposite side walls of the threaded sleeve are fixedly provided with fixing ears, the side walls of the two fixing ears are penetrated by threaded holes, the side walls of the alarm instrument body are provided with an installation groove, a display screen is installed in the installation groove, and an explosion-proof display device for blocking explosion damage is fixedly provided in the installation groove.
[0006] By adopting the above technical solution, when workers need to install the alarm body, they need to bolt the two fixing ears to the wall, allowing the alarm body to monitor the surrounding environment, and the display screen to display the surrounding environmental data in real time. During this process, if the alarm body detects that the concentration of harmful gases in the surrounding environment is higher than the preset value, the alarm body will sound an alarm. In addition, if an explosion occurs nearby, the explosion-proof display device protects the display screen, thereby reducing the probability of damage to the display screen, allowing the alarm body to continue to monitor the surrounding environment.

[0013] By adopting the above technical solution, when the staff needs to turn off the buzzer and the light strip, the staff needs to press the start switch downward, thereby causing the slide rod to slide downward under the action of the start switch, thereby causing the plastic part to move downward under the action of the slide rod, thereby causing the two plastic parts to gradually approach and eventually press against the first inclined surface, thereby causing the two electromagnets to slide away from each other, thereby causing the two electromagnets to separate from each other, thereby causing the coils of the buzzer and the light strip to lose power, thereby causing the buzzer and the light strip to stop working, thereby reducing the difficulty for the staff to turn off the buzzer and the light strip.
[0014] Furthermore, the thickness of the first PVB adhesive layer and the second PVB adhesive layer are both 0.38 mm, and the thickness of the first float glass and the second float glass are both 5 mm.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0029] like Figure 1-5 As shown, the embodiment of the present application discloses an explosion-proof alarm device, including a handle 1, an external thread 11, a threaded sleeve 12, an internal thread 13, an alarm device body 14, a fixing ear 15, a display screen 16, an explosion-proof display device 3, a slide bar 4, a start switch 41, a detection device 42, an electromagnet 43, a buzzer 44, a light strip 45, an iron sheet 46 and a plastic part 5.

The threaded sleeve 12 is a round rod-shaped structure with one end open. Its axis coincides with the axis of the handle 1. The inner wall of the threaded sleeve 12 is provided with an internal thread 13, and the external thread 11 is threadedly connected to the internal thread 13.

Two fixing ears 15 are provided and symmetrically arranged on two opposite side walls of the threaded sleeve 12, and threaded holes 2 are provided through the side walls of the two fixing ears 15. The display screen 16 is installed in the installation slot 21 and is used to display the data detected by the alarm device body 14.
[0030] When the staff needs to install the alarm body 14, they need to bolt the two fixing ears 15 to the wall, so that the alarm body 14 can detect the surrounding environment, and the display screen 16 can display the surrounding environment data in real time. During this process, when the alarm body 14 detects that the concentration of harmful gases in the surrounding environment is higher than the preset value, the alarm body 14 will sound an alarm. In addition, when an explosion occurs in the surrounding area, the explosion-proof display device 3 protects the display screen 16, thereby reducing the probability of damage to the display screen 16, so that the alarm body 14 can continue to detect the surrounding environment.

The buzzer 44, light strip 45 and iron sheet 46 are connected in series.
[0035] When the detection device 42 detects a change in the environment, the normally open contact of the detection device 42 is closed, thereby energizing the coils of the two electromagnets 43, causing the two electromagnets 43 to slide toward each other, and then the two iron sheets 46 slide synchronously with the two electromagnets 43 under the action of the two electromagnets 43, so that the two iron sheets 46 fit together under the action of the two electromagnets 43, and then the buzzer 44, the light strip 45 and the iron sheet 46 form a loop, so that the coils of the buzzer 44 and the light strip 45 are energized, and then the buzzer 44 and the light strip 45 warn the staff.
[0036] The edges where the two electromagnets 43's side walls, which are close to each other, intersect with their upper surfaces are both provided with first inclined surfaces 51. The plastic part 5 is fixedly mounted on the bottom surface of the slide bar 4.
[0037] When the staff needs to turn off the buzzer 44 and the light strip 45, the staff needs to press the start switch 41 downward, so that the slide bar 4 slides downward under the action of the start switch 41, so that the plastic part 5 moves downward under the action of the slide bar 4, so that the two plastic parts 5 gradually approach and finally press against the first inclined surface 51, so that the two electromagnets 43 slide away from each other, and then the two electromagnets 43 are separated from each other, so that the coils of the buzzer 44 and the light strip 45 lose power, and then the buzzer 44 and the light strip 45 stop working, thereby reducing the difficulty for the staff to turn off the buzzer 44 and the light strip 45.
