Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1-3, an extraction device for sampling wastewater comprises a tube body 1, a piston rod 2 is inserted into the upper end of the tube body 1, one end of the piston rod 2 arranged inside the tube body 1 is fixedly connected with a piston sheet 3, the size of the piston sheet 3 is equal to the cross-sectional size of the upper end of the tube body 1, guide sheets are arranged at the upper end and the lower end of the piston sheet 3, a hanging ring 6 is fixedly connected with the outer part of the upper end of the tube body 1, and the design of the hanging ring 6 makes the use method of the device more changeable, a person can hold the hanging ring 6 by hand, or the device is hung up through the hanging ring 6 without using the device, the arrangement of the device is convenient, the sealing performance of the device is better due to the design of a sealing ring 4, a sample storage box 7 is fixedly connected to the other side of the hanging ring 6 on the tube body 1, the mutual communication between the sample storage box 7, the piston rod 2 drives the piston piece 3 to move leftwards rapidly, so that waste water is sucked into the inner wall of the pipe body 1 through the connecting pipe, due to the arc design between the sample storage box 7 and the pipe body 1, when the waste water passes through the joint of the sample storage box 7 and the pipe body 1, the waste water flows into the sample storage box 7 to be collected, the waste water can be discharged through the water outlet pipe 8 by opening the switch valve 9, one side of the lower end of the pipe body 1 is provided with the filter screen 10, the design of the filter screen 10 can avoid that large-particle impurities enter the pipe body 1 to cause the internal blockage of the pipe body 1 and damage to the pipe body 1 in the waste water sampling process, one end of the piston rod 2 arranged outside the pipe body 1 is fixedly connected with the handle 5, the joint of the piston rod 2 and the pipe body 1 is provided with the sealing ring 4, one side below the sample storage box 7, the screw thread design between connecting pipe 12 and body 1 for the connecting pipe is convenient to be dismantled, thereby clears up filter screen 10, and the shape of connecting pipe 12 is conical, passes through screw 11 detachable connections between filter screen 10 and the body 1.

Specifically, when in use, the filter screen 10 is installed on the pipe orifice at the lower end of the pipe body 1 through the screw 11, the connecting pipe 12 is sleeved outside the lower end of the pipe body 1 and the connecting pipe 12 is rotated, so that the connecting pipe 12 is in threaded connection with the lower end of the pipe body 1 through the internal thread 13 on the inner wall thereof, the installation of the device is completed, a person holds the hanging ring 6 with one hand, the connecting pipe 12 is inserted into the wastewater, the other hand pulls the piston rod 2 to move to the left through the handle 5, the piston rod 2 drives the piston sheet 3 to move to the left rapidly, thereby the wastewater is sucked into the inner wall of the pipe body 1 through the connecting pipe, due to the arc design between the sample storage box 7 and the pipe body 1, when the wastewater passes through the joint of the sample storage box 7 and the pipe body 1, the wastewater flows into the sample storage box 7 to be collected, the, large granule impurity gets into 1 inside pipe body that leads to of body 1 and blocks up, cause the damage of body 1, the screw thread design between connecting pipe 12 and the body 1, make the connecting pipe conveniently dismantle, thereby clear up filter screen 10, the design of link 6, make the application method of this device more changeable, link 6 can be handed to the people, perhaps hang this device through link 6 not using this device, the arrangement of the device of being convenient for, the design of sealing ring 4 makes the leakproofness of this device better.
