The liquid is filtered by the filter portion 12 before entering the inlet 18. The filter portion 12 may be a graphene filter sponge. The inside of filter part 12 is offered and is used for dodging the recess of inlet tube 11, and the tip of inlet tube 11 inserts in the recess for the liquid homoenergetic that gets into water inlet 18 can be through filtering. The fixed pipe 19 is provided to be easily detached from the feed pipe 11 so as to wash the filter part 12.
As a specific embodiment of the wetland water quality testing equipment provided by the utility model, please refer to fig. 1, the liquid collecting bottle 7 is screwed on the first sleeve 3. Because the first sleeve 3 is hinged on the fixed cylinder 1, the second sleeve 5 is arranged on the first sleeve 3 in a suspended sliding manner. If the liquid collecting bottle 7 is arranged on the second sleeve 5, the load moment is inevitably too large, and the stability is not convenient. The drip bottle 7 is thus arranged on the first sleeve 3. Simultaneously in order to take off the liquid collecting bottle 7 after collecting liquid, the bottle mouth of the liquid collecting bottle 7 is connected to the first sleeve 3 in a threaded mode. For this reason can be fixed with connecting seat 20 in the bottom of first sleeve 3, offer the screw hole that is used for with liquid collecting bottle 7 threaded connection on the connecting seat 20, the screw hole sets up with first cavity 4 intercommunication to guarantee that liquid collects in liquid collecting bottle 7 under the effect of gravity behind the entering first cavity 4.
As a specific embodiment of the wetland water quality detection equipment provided by the utility model, please refer to fig. 1 and 3, the inner diameter of the fixed cylinder 1 is greater than the inner diameters of the first sleeve 3 and the second sleeve 5. The air suction piston 13 is arranged in the air suction cavity 2 in a sliding mode, the liquid collecting bottle 7 is connected to the first sleeve 3, the liquid collecting bottle 7 can be filled with liquid, and the distance for the air suction piston 13 to move is reduced, so that the inner diameter of the fixing cylinder 1 is larger than the inner diameters of the first sleeve 3 and the second sleeve 5, and the liquid can be filled in the liquid collecting bottle 7 by the aid of the smaller distance for upwards pulling the air suction piston 13. For example, the inner diameter of the first sleeve 3 is 15mm, the inner diameter of the second sleeve 5 is 10mm, and the inner diameter of the fixed cylinder 1 is 50 mm.
As a specific implementation manner of the wetland water quality detection device provided by the utility model, please refer to fig. 1, the second casing 5 is sleeved with a flexible grip 17.
