Detailed Description
The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.
Referring to fig. 1, the field smoke intensity testing device of the utility model comprises a mounting box 1, a high-precision smoke meter 2, a hot air fan 4, a thermometer 5 and a controller, wherein the high-precision smoke meter 2, the hot air fan 4, the thermometer 5 and the controller are arranged in the mounting box 1.
The test channel 3 of the high-precision smoke meter 2 penetrates through and extends to the outer side of the installation box 1, and is used for collecting smoke from the field.
The hot air output end of the hot fan 4 faces the high-precision smoke meter 2 and is used for heating the high-precision smoke meter 2.
The thermometer 5 is used to monitor the temperature in the mounting case 1.
The controller is used for collecting the temperature signal output by the thermometer 5, comparing the temperature signal with a set temperature threshold value, and controlling the thermal fan 4 to work in a first power state, a second power state or a third power state according to the comparison result. The three states of the thermal fan 4 are respectively used for quickly preheating and heating the high-precision smoke meter 2, stably heating and heating, and keeping the service environment temperature of the high-precision smoke meter 2, so that the stability of temperature improvement is ensured while the service environment temperature of the high-precision smoke meter 2 can be quickly improved, and the problem that the final temperature in the mounting box 1 exceeds the set highest temperature threshold value due to the excessively quick temperature rise is effectively solved.
Specifically, the first power state is the operation of the hot air fan 4 at rated power. When the temperature signal is smaller than the set minimum temperature threshold, the hot air fan 4 works in the first power state, and rapid preheating and heating of the high-precision smoke meter 2 in a cold state are realized.
The second power state is that the hot air fan 4 operates at 1/2 of the rated power. When the temperature signal is greater than or equal to the set minimum temperature threshold and less than the set maximum temperature threshold, the hot air fan 4 works in the second power state, and stable heating and temperature rise of the high-precision smoke meter 2 are realized.
The third power state is that the hot air fan 4 operates with power that keeps the temperature in the mounting box 1 at the set maximum temperature threshold. When the temperature signal is equal to the set highest temperature threshold, the hot air fan 4 works in the third power state, so that the use environment temperature of the high-precision smoke meter 2 is kept, and the normal work of the high-precision smoke meter 2 is ensured.
The entire cost of the test device can be effectively reduced by heating the high-precision smoke meter 2 by the hot fan 4, but the temperature inside the installation box 1 is difficult to control. Therefore, the present utility model sets an error allowance zone at the set maximum temperature threshold. The error allowable section is + -10% of the set maximum temperature threshold. I.e. when the temperature inside the mounting box 1 is between 90% and 110% of the set maximum temperature threshold, the optimal use environment temperature of the high-precision smoke meter 2 is considered to be reached.
A plurality of rollers 6 are rotatably arranged below a mounting box 1 of the testing device, so that the whole movement of the testing device is convenient. In addition, the handle is installed to the top of install case 1, makes things convenient for testing arrangement's whole transport.
In order to reduce the influence on the flue gas collected by the test channel 3, one side of the mounting box 1 far away from the test channel 3 is provided with an air inlet which is communicated with the air inlet end of the hot air fan 4 through a pipeline. An air outlet is formed in the bottom of the installation box 1, and an air outlet pipe 7 extending to one side of the bottom of the installation box 1 is arranged in the air outlet. The mode that the end portion is adopted to admit air and the bottom is led out to the side edge of the installation box 1 is adopted, so that the air inlet end and the air outlet end of the installation box 1 are far away from the test channel 3, the influence on the smoke collected by the test channel 3 is reduced, and the detection precision of the high-precision smoke meter 2 is guaranteed.
Preferably, waterproof shutter and dust screen are installed in the air inlet, and the dust screen is installed at the mouth of pipe outlet 7, can prevent dust and mosquito from entering into installation box 1.
The working principle of the utility model is as follows: when the high-precision smoke intensity test is required to be carried out in the field, the testing device is moved to a set position. Then the power supply of the hot fan 4 is turned on to power up the same. At this time, the hot fan 4 can generate hot air to heat the high-precision smoke meter 2. When the temperature in the installation box 1 rises to the set highest temperature threshold value, the high-precision smoke meter 2 can be powered on. The smoke intensity test in the field is realized through the high-precision smoke intensity meter 2.
