[0002] Cleanrooms, also known as dust-free workshops, clean rooms or clean rooms, are mainly used for indoor pollution control and are used to produce parts that are sensitive to pollution. Cleanrooms require specific operating procedures to control the concentration of suspended particles in the air in order to achieve the appropriate particle cleanliness level, so it is necessary to detect and alarm the concentration of suspended particles in the air.

This has limitations in actual use and affects the accuracy of the detection. In addition, most alarm devices in clean rooms sound alarms through buzzers. In this way, the alarm can only be sounded, and the alarm device cannot be visualized, which affects the effect of the alarm. Utility Model Content

[0021] The side panel 1 is an L-shaped panel. There are two side panels 1 and they are symmetrically distributed at both ends of the top panel 2. Both ends of the lifting screw rod 5 are rotatably connected to the side panel 1 and the top panel 2 respectively. One end of the worm 4 is rotatably connected to the side of the top panel 2. The worm 4 is meshed with the worm wheel 6. Two symmetrical threaded holes are provided on the lifting plate 7. The lifting plate 7 is threadedly connected to the lifting screw rod 5 through the threaded holes. The side of the ear plate 8 is rotatably connected to one end of the moving screw rod 10. The side of the ear plate 8 is welded and fixed to one end of the limit rod. The worm 4 is rotated by the dual-axis motor 3. The worm 4 is used to make the lifting screw rod 5 and the worm wheel 6 rotate synchronously, so that the lifting screw rod 5 is lifted and lowered to adjust the height of the concentration detector 12. The moving screw rod 10 is rotated by the driving motor 9, so that the moving plate 11 is horizontally moved outside the limit rod to realize concentration detection. The horizontal position adjustment of the instrument 12 expands the detection area of ​​the concentration detector 12 and improves the accuracy of the clean room concentration detection. The movable plate 11 is threadedly connected to the outer side of the movable lead screw 10 through a threaded hole. The movable plate 11 is slidably connected to the limit rod through a circular through hole. The spring 20 is located between the two contact plates 18. The contact plate 18 is composed of a guide sleeve and a guide rod slidably connected. When the electromagnet 15 is energized, the magnetic block 19 will be attracted, thereby driving the contact plate 18 and the spring 20 to stretch. The charged contact plate 18 and the contact head 16 are in contact, so that the lamp tube 13 lights up. When the contact head 16 is powered off, the contact plate 18 is separated from the contact head 16 under the pulling force of the spring 20, so that the lamp tube 13 is extinguished. In this way, when the concentration detector 12 sends an alarm signal, the lamp tube 13 will flash to make the alarm visual.

[0022] Working principle: When in use, the staff rotates the worm 4 through the dual-axis motor 3, and uses the worm 4 to make the lifting screw 5 and the worm wheel 6 rotate synchronously, so that the lifting screw 5 is lifted and lowered to adjust the height of the concentration detector 12. The moving screw 10 is rotated by the driving motor 9, so that the moving plate 11 moves horizontally outside the limit rod to adjust the horizontal position of the concentration detector 12, effectively enhancing the flexibility of the detection position of the concentration detector 12, expanding the detection range of the concentration detector 12, and improving the accuracy of the concentration detector 12 in the clean room detection. When the concentration detector 12 detects that the concentration is too high, the concentration detector 12 will move horizontally. When the voltage is high, the electromagnet 15 will be energized intermittently, which will attract the magnetic block 19 to move the contact plate 18 and stretch the spring 20. When the contact plate 18 is in contact with the contact head 16, the lamp 13 will light up. While the contact plate 18 moves, the bell tongue 21 moves synchronously and strikes the bell bowl 22 to sound an alarm. When the contact head 16 is powered off, the contact plate 18 is reset under the pulling force of the spring 20, so that the contact plate 18 is separated from the contact head 16. At this time, the lamp 13 is extinguished. Therefore, the intermittent energization of the electromagnet 15 can achieve the strobing of the lamp 13 and the alarm sound of the bell bowl 22, thereby improving the alarm effect of the device.
