Further, the fixing rods 105 are fixedly installed on the lower surface of the supporting ring 101, and the lower surfaces of the fixing rods 105 on the two corresponding supporting rings 101 are fixedly connected through the bottom plate 106, so that the device can be stably placed in a field environment.
The working principle is that the position shown in fig. 1 is the to-be-operated state of the sampling part 5, the motor 2 and the electric heating pipe 603 are started to preheat, the transmission shell 4 is driven to rotate, the sampling part 5 is gradually unfolded, one end with the one-way valve 502 is gradually contacted with the water surface to be sampled downwards, after the end arrives, the negative pressure pump 3 is started to absorb liquid through the negative pressure cavity 401 of the transmission shell 4 and the inner cavity of the sampling part 5, the use time of the negative pressure pump 3 is calculated, the liquid amount absorbed by the sampling part 5 can be obtained, the motor 2 is reversely rotated to lower the sampling part 5 with liquid, the sampling part 5 is placed between the upper heat sealing plate 602 and the lower heat sealing plate 601 near the part of the sampling liquid, the sampling part 5 is heated and extruded through extrusion and heat transfer, the heat sealing effect is achieved, then the other end is removed from the one-way valve 502 and extruded part of the liquid is repeatedly subjected to sealing operation, or a wood plug is adopted for sealing.
In the description of the present invention, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.
The above embodiments are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope defined by the claims of the present invention without departing from the design spirit of the present invention.
