It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a dust monitoring device. Figure 1-4 As shown, the dust monitoring device includes: a base 1, the base 1 is provided with a plurality of through holes around the center, a servo motor 2 is fixedly mounted on the top center of the base 1, and a screw 3 is fixedly mounted on the output shaft of the servo motor 2; a screw sleeve 4 is threadedly mounted on the screw 3, a mounting seat 5 is fixedly mounted on the top of the screw sleeve 4, a mounting groove is provided on the top of the mounting seat 5, and a groove is provided on the inner wall of one side of the mounting groove; a mounting block 6 is arranged in the mounting groove, a dust sensor 7 is fixedly mounted on the top of the mounting block 6, and a fixing groove is provided on one side of the mounting block 6; two support rods 8 are fixedly mounted on the top of the base 1 and symmetrically distributed about the screw sleeve, The support rod 8 is provided with multiple slots along the height direction; a support plate 9 is fixedly sleeved on the outside of the screw sleeve 4, and the support plate 9 is provided with two openings that slide with the corresponding support rods 8, and the support plate 9 is provided with two cavities close to the openings, and the two cavities are provided with sliding holes on the side facing the openings; multiple support legs 10 are fixedly installed on the bottom of the support plate 9, and the bottom ends of multiple support legs 10 respectively pass through multiple through holes, and the bottom ends of multiple support legs 10 are fixedly installed with universal wheels; two positioning mechanisms are respectively assembled on the two cavities for fixing the support plate 9 with the slots; a disassembly mechanism is installed on the mounting seat 5 for fixing the mounting block 6.

[0023] When the dust sensor 7 is adjusted to a suitable height, the dust monitoring device 7 can be operated. The dust monitoring device 7 can be adjusted to a suitable height, and the dust monitoring device 7 can be adjusted to a suitable height ... To ensure the accuracy and stability of monitoring, after the support plate 9 stops moving, the positioning mechanism can be used to fix the support plate 9 on the support rod 8, so that the support rod 8 can support the support plate 9, which can effectively reduce the supporting force of the screw 3 and the screw sleeve 4 on the support plate 9, and can also effectively reduce the supporting force of the screw 3 on the mounting seat 5, thereby providing better protection for the screw 3. When the dust sensor 7 is damaged, the disassembly mechanism can be used to quickly release the fixation of the mounting block 6. After releasing, the mounting block 6 can be taken out of the mounting groove to complete the removal of the dust sensor 7, and then the mounting block 6 at the bottom of the new dust sensor 7 is placed into the mounting groove, and then the disassembly mechanism is used to fix the mounting block 6, thereby completing the installation of the dust sensor 7, and replacement is relatively convenient and quick.

[0024] In a further preferred embodiment of the present invention, the positioning mechanism includes: a positioning rod 11 slidably installed in the sliding hole, one end of the positioning rod 11 extends from the sliding hole and is compatible with any one of the card slots; an iron plate 12 fixedly installed at the other end of the positioning rod 11; two first springs 13 fixedly installed on the inner wall of the cavity facing the opening side and between the iron plate; and an electromagnet 14 fixedly installed on the inner wall of the cavity away from the opening side.

[0025] In this embodiment, the positioning mechanism is used to fix the support plate 9. When the support plate 9 needs to be fixed, the electromagnet 14 only needs to be powered off to release the magnetic attraction of the electromagnet 14 to the iron plate 12. After the release, the first spring 13 will automatically pull the iron plate 12 to move through its elasticity, and the iron plate 12 will drive the positioning rod 11 to move until the positioning rod 11 is inserted into the corresponding slot on the support rod 8. After insertion, the support rod 8 can support the support plate 9, which can effectively reduce the supporting force of the screw 3 and the screw sleeve 4 on the support plate 9, and can also effectively reduce the supporting force of the screw 3 on the mounting seat 5, thereby providing better protection for the screw 3.

[0026] In a further preferred embodiment of the present invention, the disassembly mechanism includes: a pull rod 15 slidably mounted on the inner wall of one side of the groove, one end of the pull rod 15 extends to the outside of the mounting seat 5; a second spring 16 slidably sleeved on the pull rod 15; a baffle 17 fixedly mounted on one end of the pull rod 15, a clamping block 18 fixedly mounted on one side of the baffle 17, and the clamping block 18 is adapted to the fixing groove.

[0027] In this embodiment, the disassembly mechanism is used to fix the mounting block 6. When the damaged dust sensor 7 needs to be replaced, the pull rod 15 is pulled to one side so that the pull rod 15 drives the baffle 17 to move, so that the baffle 17 squeezes the second spring 16 and drives the card block 18 to disengage from the fixed groove of the mounting block 6. After disengagement, the mounting block 6 can be taken out from the mounting groove to complete the removal of the dust sensor 7.

The baffle 17 will push the card block 18 into the fixed groove of the mounting block 6, thereby completing the installation of the dust sensor 7. The replacement is relatively convenient and quick.

[0028] In a further preferred embodiment of the present invention, two armrests are fixedly installed on the top of the base 1, and both armrests are made of metal.

[0029] In this embodiment, the use of the handrail can facilitate the staff to push the device. When pushing, the universal wheels need to be in contact with the ground.

[0030] In a further preferred embodiment of the present invention, a plurality of pads 19 are fixedly mounted on the bottom of the base 1 , and anti-slip pads are fixedly mounted on the bottoms of the plurality of pads 19 .

[0031] In this embodiment, by using multiple pads 19 and multiple anti-slip pads, the friction between the device and the ground can be increased, preventing the device from shaking or shifting during use. This is especially important for using the dust monitoring device on wet, smooth or inclined ground, ensuring the safety and stability of the device.

[0032] In a further preferred embodiment of the present invention, the top ends of the two support rods 8 are fixedly mounted with limit plates, and the two limit plates are both circular.

[0033] In this embodiment, the circular limiting plate can prevent the support plate 9 from being separated from the support rod 8 due to excessive upward movement, thereby providing better protection.

[0034] In a further preferred embodiment of the present invention, a handle is fixedly mounted on one end of the pull rod 15, and the screw rod 3 is made of stainless steel.

[0035] In this embodiment, the use of the handle can greatly improve the convenience of personnel operating the pull rod 15. Personnel can easily pull the pull rod 15 by holding the handle without directly holding the pull rod 15 itself. The stainless steel screw 3 has excellent rust and corrosion resistance and can be used for a long time in harsh environments such as humidity and dust without being easily damaged.

[0036] In summary, compared with the related art, this solution can facilitate the staff to use the handrail to move the device through the use of multiple universal wheels, and can move the device to the location to be monitored more easily. Through the coordinated use of the servo motor 2 and the screw 3, the screw sleeve 4 can drive the mounting seat 5 to move vertically, and the screw sleeve 4 can also drive the support plate 9 to slide vertically on the support rod 8, so that the dust sensor 7 can be adjusted to a suitable height to monitor the dust, which can meet different monitoring needs. During the movement of the support plate 9, it will drive the support leg 10 to move, so that the universal wheel at the bottom of the support leg 10 can be off the ground. After the universal wheel is off the ground, the device The support plate 9 can be fixed on the support rod 8 through the positioning mechanism, so that the support rod 8 can support the support plate 9, which can effectively reduce the supporting force of the screw 3 and the screw sleeve 4 on the support plate 9, and can also effectively reduce the supporting force of the screw 3 on the mounting seat 5, which can better protect the screw 3. The use of the disassembly mechanism can facilitate the staff to remove and install the dust sensor 7, so that the damaged dust sensor 7 can be replaced more quickly, and the operation is more convenient.
