DETAILED DESCRIPTION

[0020] In order to better understand the technical content of the present application, a specific embodiment is provided below, and the present application is further described in combination with the drawings.

[0021] Referring to Figures 1 to 3The utility model provides a kind of multi-path flue gas collector for environmental detection, including collection box 1, baffle 2, sampling head 3, filter 4, bellows 5, air pump 6 and locking mechanism, the baffle 2 is divided into several storage cavities 7 in collection box 1, the sampling head 3, filter 4, bellows 5 and air pump 6 are sequentially arranged from top to bottom, the air pump 6 is arranged in the top surface of collection box 1, and is communicated with storage cavity 7;The locking mechanism includes mounting rod 8, locking rod 9, storage cylinder 10, metal rod 11, spring 12, electromagnet 13, pressure sensor 14 and main control unit 15, the mounting rod 8 is symmetrically set in the both sides of filter 4, the top end of locking rod 9 is connected with the bottom surface of mounting rod 8, and threading hole 16 is arranged on it, the storage cylinder 10 is oppositely set on the top surface of collection box 1, and is located below locking rod 9, the cavity 17 is opened in the inner wall of storage cylinder 10, the metal rod 11 is located in cavity 17, the spring 12 is connected with the end part of metal rod 11 and the inner wall of cavity 17, the electromagnet 13 is set in the inside of the side wall of storage cylinder 10 opposite to metal rod 11, the pressure sensor 14 is set in the inner bottom surface of storage cylinder 10, the main control unit 15 is set in the side wall of collection box 1, and is electrically connected with electromagnet 13 and pressure sensor 14 respectively.

[0022] Multiple baffle plates 2 are arranged in collection box 1, baffle plate 2 can divide collection box 1 into multiple storage cavities 7, each storage cavity 7 can be used for storing flue gas, air pump 6 is arranged above storage cavity 7, filter 4 is connected with air pump 6 through bellows 5, and sampling head 3 is arranged on the top of filter 4, by pulling filter 4, sampling head 3 can be moved to different sampling points, and then air pump 6 starts, and flue gas can be sucked into storage cavity 7 through sampling head 3, filter 4 and bellows 5 for storage, to improve sampling efficiency and coverage.

[0023] When the sampling task is not performed, the locking rod 9 on the rod 8 on both sides of the filter 4 is inserted into the storage cylinder 10 to realize the placement of the sampling head 3. The pressure sensor 14 is arranged on the inner bottom surface of the storage cylinder 10. When the locking rod 9 is inserted into the storage cylinder 10, the pressure data detected by the pressure sensor 14 increases and is sent to the main control unit 15. When the sampling head 3 moves to the sampling point for sampling, the locking rod 9 also leaves the pressure sensor 14, and the pressure data detected by the pressure sensor 14 becomes 0. The main control unit 15 can evaluate the use time length of the corresponding flue gas collection channel according to the pressure data collected by the pressure sensor 14.
