Problems solved by technology

However, in the prior art, such as the automatic rain and dust sampling collection monitoring system disclosed in the above-mentioned patents, in order to realize the sampling and collection of atmospheric dust and rainfall, dust collection boxes and water collection boxes are adjacently arranged on both sides. When the height of the system from the ground is not lower than 1.5m or even 5-15m through the support frame, it is difficult to ensure the stability of the entire collection and monitoring system with the triangular support used to stabilize the collection and monitoring system, especially However, when the amount of liquid collected in the water collection tank is increasing and the wind speed is high, it is more difficult to maintain the balance of the collection and monitoring system only by relying on the triangular bracket

Embodiment 1

[0057] Such as figure 1 As shown, an atmospheric deposition collection device at least includes a fixed bracket 1 and a dust collection device 2 and a liquid collection device 3 arranged side by side. The rotating device 4 arranged on the fixed support 1 and the balance member 5 arranged on the movement space of the dust collecting device 2 and / or the liquid collecting device 3 can move back and forth.

[0058] The wind force and direction information is detected by the wind force and direction detection device 14, and the liquid level position information is obtained by detection by the liquid level sensor 13. The second data processing module 7 processes the liquid level position information to obtain the current weight information and / or Weight change information and current weight information and / or weight change information of the atmospheric deposition collection device.

[0059] Wherein, when the rotation device 4 does not perform the rotation operation, the current we...

Embodiment 2

[0081] A sedimentation detection method for an atmospheric deposition collection device, in particular to a sedimentation detection method for a wet deposition atmospheric deposition collection device, at least including the following steps:

[0082] S1: Blank test group.

[0083] s1: Take an appropriate amount of deionized water and put it in a 500ml beaker, add an appropriate amount of agar powder to mix, and prepare an agar solution with an appropriate concentration.

[0084] s2: place the beaker containing the agar solution on an electric heating plate, and heat at high temperature while stirring with a clean glass rod.

[0085] s3: Stop heating until the solution in the beaker evaporates and concentrates to nearly 50ml, continue stirring and use the residual heat of the solution in the beaker to concentrate it to 50ml, and stop stirring when the remaining temperature drops to a certain temperature range to obtain a reference solution.

[0086] s4: Prepare several polyeth...

Embodiment 3

[0121] This embodiment is a further improvement on the basis of Embodiment 1, and only the improved part will be described.

Abstract

The invention relates to an atmospheric sedimentation collection device. The atmospheric sedimentation collection device at least comprises fixing supports, a dust collecting device and a liquid collecting device and also comprises a first data processing module, a rotating device and a balancing part configured to move back and forth in movement space of the dust collecting device and / or the liquid collecting device, and in response to the first moment when information that wind power received by the atmospheric sedimentation collection device is not smaller than current weight of the atmospheric sedimentation collection device is detected, the rotating device can drive the dust collecting device and the liquid collecting device to jointly rotate relative to the fixing supports accordingto determined first rotation strategy or second rotation strategy in a manner of assisting the atmospheric sedimentation collection device in reducing the wind load resistance of the atmospheric sedimentation collection device and enables the balancing part to move in the movement space in a manner of at least partially counteracting unbalanced load of the atmospheric sedimentation collection device, wherein the first rotation strategy and the second rotation strategy are used for reducing the secondary dusting influence caused by wind power and direction information on the dust collection device to the greatest extent.

Description

technical field [0001] The invention relates to the fields of environmental protection technology and atmospheric environment detection technology, in particular to an atmospheric deposition collection device and a deposition detection method. Background technique [0002] Atmospheric particulate matter is solid or liquid particulate matter in the atmosphere, mainly including particulate matter released into the atmosphere by natural and man-made pollution sources, such as soil particles, sea salt particles, combustion smoke, pollen, etc. Among them, atmospheric deposition particulate matter is a component that has a short suspension time in the air and can settle to the surface under its own gravity. Due to the relatively large proportion of such substances in the atmosphere and weak transmission power, they have become the cause of local and regional environmental degradation. One of the important sources of pollution. In recent years, with the continuous deterioration of...
