Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an environmental monitoring device for environmental protection. Background Art

[0002] Environmental dust monitoring devices used on construction sites are designed to control and reduce air pollution generated during construction, especially in the material stacking areas of the construction site.

[0003] In the material stacking area of ​​the construction site, if there is strong wind, it will cause excessive dust in the material stacking area. The use of environmental protection dust monitoring devices can achieve real-time monitoring and timely alarm, so that the environmental protection department of the construction site can carry out timely dust reduction treatment.

[0004] The environmental dust monitoring device used in the construction site generally installs a bracket in the material stacking area, and a suspended particle monitor is set on the bracket. A sampling tube and an exhaust pipe are set on the suspended particle monitor. The sampling tube will extract the ambient dust air in the material stacking area of ​​the construction site for a certain period of time, and input the sampled ambient dust air into the suspended particle monitor. The suspended particle monitor will detect the concentration of dust particles in the sampled ambient dust air, and measure the particle concentration in the sampled ambient dust air extracted and captured by the preset optical sensor, weight detection device or beta-ray absorption method in the suspended particle monitor. If it exceeds the standard, an alarm will be sounded through the alarm.

[0005] At present, the existing environmental dust monitoring devices used in construction sites will discharge dust through the exhaust pipe preset on the suspended particle monitor after the sampling and detection is completed. Generally, an exhaust fan will be set in the suspended particle monitor to ensure that there is suction force in the sampling tube. The exhaust pipe and the sampling tube have inner cavities that are mostly exposed. When not in use, it is easy for insects and rodents to enter the tube cavity, which will affect the normal environmental monitoring and detection work of the suspended particle monitor in the later stage.

[0006] In addition, the alarms of existing environmental dust monitoring devices used in construction sites mostly sound alarms in one direction, which greatly reduces the effective range of the alarm sound.

[0007] The above problems are widespread and urgently need to be improved. Utility Model Content

[0029] The alarm 81 and its speaker 82 are both prior art.

[0030] The monitor body 2, the vertical cylinder 71, the control box 72, the rotary motor 73, and the alarm 81 are electrically connected. A PLC is preset in the control box 72, and related equipment is connected to a nearby power supply box through a preset power line.

[0031] The first baffle plate 4 and the second baffle plate 5 are respectively symmetrically arranged on the lower end surface of the lifting frame plate 3, the first seal 41 is arranged toward the sampling tube 21, and the second seal 51 is arranged toward the exhaust pipe 22. The first seal 41 and the second seal 51 are made of highly elastic vulcanized rubber as a whole with a thickness of thirty to forty centimeters, which can squeeze and seal the open end surfaces of the sampling tube 21 and the exhaust pipe 22.

[0032] The inner wall surfaces of the first gasket 41 and the second gasket 51 are both provided with a smoothing layer 6. The smoothing layer 6 is a polyester resin coating. The thickness of the smoothing layer 6 is fifty to sixty microns, which improves the smoothness of the first gasket 41 and the second gasket 51 when covering the sampling tube 21 and the exhaust pipe 22 respectively.

[0033] The mounting base 8 is an L-shaped structural plate as a whole, and the loudspeaker cover 83 is installed at the right end of the speaker 82. The loudspeaker cover 83 is made of glass fiber, has excellent sound amplification effect, has good acoustic characteristics, can effectively reduce resonance, and is light in weight.

[0034] A guide slot 31 is provided on the lifting frame plate 3, and the lifting frame plate 3 is slidably connected with the equipment support 1 through the guide slot 31. The top view cross-sections of the guide slot 31 and the equipment support 1 are both rectangular structures, which prevents the lifting frame plate 3 from horizontal rotation.

The guide ball 321 is in rolling contact with the outer wall surface of the equipment bracket 1. The guide ball 321 is made of hard alloy steel with high strength and no deformation.

[0036] Working mode: When the monitor body 2 is not in use, the monitor body 2 will give the control box 72 through the signal line.

After the first baffle plate 4 squeezes and seals the right end face of the sampling tube 21 through the first gasket 41, and the second baffle plate 5 squeezes and seals the left end face of the exhaust pipe 22 through the second gasket 51, the PLC in the control box 72 will control the closing of the vertical cylinder 71 to prevent insects and rodents from directly entering the inner cavity of the sampling tube 21 and the exhaust pipe 22, which will affect the normal environmental monitoring and detection work of the monitor body in the later stage, and improve the insect and rodent prevention of the sampling tube 21 and the exhaust pipe 22 on the monitor body.

[0037] Moreover, when the monitor body 2 is used for monitoring (the specific use has been recorded in the background technology of this patent and is the prior art), if the collected ambient air contains particulate matter concentration exceeding the standard, the monitor body 2 will give a signal to the control box 72, and the PLC in the control box 72 will control the start of the rotating motor 73 and the alarm 81. The rotating motor 73 drives the alarm 81 to rotate at a constant speed horizontally while amplifying the sound alarm, avoiding the situation where the alarm makes a sound alarm in one direction, and combined with the loudspeaker sleeve 83, the effective range of the alarm sound is greatly improved.

[0038] In addition, when the lifting frame plate 3 moves vertically along the equipment support 1, the guide balls 321 will roll along the outer wall surface of the equipment support 1, further improving the vertical sliding smoothness of the lifting frame plate 3.
