Sampling unit is set to the front end of acquisition channel, for acquiring aerosol and suspended particulate substance in air；
Flowmeter is set between the front end and middle-end of acquisition channel, the flow for measuring air in acquisition channel；
Power source is set to the tail end of acquisition channel, for providing the power for extracting sample；The sampling unit, flowmeter
It is connected by acquisition channel with power source；
Temperature measurement module is installed on power source, the temperature for detecting power source；
Controller is connected with flowmeter, power source, temperature measurement module respectively, for acquire data that flow measurement measures,
The temperature of power source, and the keying of power source is controlled, when flow is less than setting value/and temperature is more than setting value, control power
Source is closed.
Further, the sampling unit includes mounting table, at least one filter membrane on mounting table and is set to
The sampling cabin of acquisition channel front end.
Further, the temperature measurement module is P/T module.

The utility model realizes sampler in stall and mistake by flowmeter, temperature measurement module and the controller in sampler
Protection control when hot.
When sampler is run, flowmeter grasps sampler operation conditions by sampler air inlet gas flow, works as sampling
After device completes starting operation and enters sample states, such as occur continuing 1s or more actual flows are less than target flow 90%, then in
It only samples and alarms.
When sampler is run, temperature measurement module can monitor sampler core component heat condition in real time, when detection temperature is higher than
When safe temperature, sampler stops to sample and alarm.
It can effectively judge wind turbine stall and superheating phenomenon by dual judgment mechanism and have to sampler core component
Effect protection.
The utility model has the beneficial effects that：1, has the function of continuous sampling, it can be achieved that 24 hours uninterruptedly continuously adopt
Sample keeps sample more representative；2, can be automatically controled the start and stop of pump, solve legacy sampler damage acquisition all, burn out pump
Problem realizes self-protection；3, are quick on the draw to acquisition abnormity situation, effective protection equipment, and reliability is high.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific implementation mode
In order to make those skilled in the art be better understood from the utility model, below in conjunction with the utility model reality
