Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0019] Such as figure 1 As shown, the structure of the automatic ventilating balloon radon measuring instrument is shown, including: a host, a radon gas collection chamber and a tripod bracket. The host includes a radon gas sampling device, an automatic gas path switching device and a probe, wherein

[0020] Radon gas sampling device, used to collect and filter radon gas;

[0021] The gas circuit automatic switching device is used for the smooth switching between the gas circuits when the balloon is pumped or the balloon is exhausted, and the air circuit is reversible.

[0022] The above-mentioned radon gas sampling device, gas circuit automatic switching device and probe are installed inside the main engine, and metal plates are used for ...

Abstract

The invention discloses an automatic ventilation type balloon emanometer, comprising a main engine, a radon gas collecting chamber and a triangular bracket. The main engine comprises a radon gas sampling device, an automatic gas path converting device and a probe, wherein the radon gas sampling device is used for collecting and filtering radon gas; and the automatic gas path converting device is used for smoothly converting gas paths in a process of pumping or venting gas to a balloon, so that a reversible airflow loop is realized. According to the automatic ventilation type balloon emanometer provided by the invention, the radon gas sampling device and the probe are mounted in the same main engine, and the step of manually replacing the gas paths is omitted through the automatic gas path converting device, so that the leakage of gas in a manual replacement process can be avoided, and the reliability of the balloon emanometer can be improved; and the automatic ventilation type balloon emanometer is mounted on the triangular bracket, so as to be conveniently used outdoors.

Description

technical field [0001] The invention relates to a radon measuring instrument, in particular to an automatic ventilation type balloon radon measuring instrument. Background technique [0002] Radon is a radioactive gas, and its half-life is 3.824 days in the radioactive series of uranium series; its first-generation daughter 218 The half-life of Po is 3.05min, the second generation daughter 214 The half-life of Pb is 26.8min, the third generation daughter 214 The half-life of Po is 26.8min. The balloon method for measuring radon is a fast and accurate method for measuring radon, which has the characteristics of simple operation, convenient portability and high sensitivity. [0003] The radon measurement by the balloon method is divided into the following five stages, the pumping stage, the waiting stage, the exhaust stage, the daughter measuring stage and the radon gas measuring stage. In the pumping stage, install the filter membrane 1 at the air inlet, pump air into the...
