Furthermore, the inner side of the water inlet seat 3 is of a hourglass-shaped structure with thick top and bottom and thin middle, so that a hole in the middle of the water inlet seat 3 is conveniently plugged through the sealing plunger 11, and an anti-leakage effect is achieved.
Further, sealed plunger 11 is located the bottom inboard of water inlet seat 3, and the cross-sectional diameter of sealed plunger 11 is greater than the diameter at the thinnest position in the middle of water inlet seat 3, sealed plunger 11 is inside to be the lead block, the external fixation parcel has the soft rubber of one deck, when main sampling piece 1 reachs suitable degree of depth, continue to loosen main stay cord 7, link 5 and the sealed plunger 11 of bottom can continue the lapse, thereby make the opening at water inlet seat 3 top spill, sewage just so can get into in the inboard basin in main sampling piece 1 top, then upwards stimulate main stay cord 7 again, link 5 can drive sealed plunger 11 rebound again at this moment and will water inlet seat 3 middle pore stifled die, can enough avoid the sample to outwards ooze after the sample is accomplished like this, can avoid the sewage of other depths to cause the pollution to the sample again, it is more accurate to take a sample.
Further, the connecting frame 5 is of a cross-shaped structure, four round holes are symmetrically and fixedly arranged on the outer side of the connecting frame, the four round holes are embedded with the four guide rods 4, and the connecting frame 5 can slide up and down on the inner sides of the four guide rods 4, so that sewage can conveniently flow into the water tank on the inner side of the top of the main sampling block 1.
Further, the equal fixedly connected with thread head in bottom of suspension rope 8, and this thread head homoenergetic connects fixed mounting at suspension rope connecting seat 2 tops through twisting, suspension rope 8's top still equal fixedly connected with one with the connecting seat that suspension rope connecting seat 2 tops internal screw seat specification is the same, suspension rope 8 of suitable height is connected in 1 both sides of main sampling piece according to the sewage degree of depth in sample place earlier during the use, earlier connect with the fixed twisting in thread head and the suspension rope connecting seat 2 tops of 8 bottoms of a suspension rope during the connection, then connect with the fixed twisting of the thread head and the connecting seat at 8 tops of first suspension rope of second suspension rope 8 bottoms, after being connected to suitable length, connect the thread head of floater connecting seat 9 through the bottom and the fixed twisting of the connecting seat at the 8 tops of suspension rope of top, can easily be applicable to different sampling depth.
The working principle is as follows: when the device is used for sampling sewage, the suspension ropes 8 with proper height are connected with the two sides of the main sampling block 1 according to the sewage depth of a sampling place, when in connection, the thread head at the bottom of one suspension rope 8 is fixedly screwed with the top of the suspension rope connecting seat 2, then the thread head at the bottom of the second suspension rope 8 is fixedly screwed with the connecting seat at the top of the first suspension rope 8, after being connected to a proper length, the floating ball connecting seat 9 is fixedly screwed with the connecting seat at the top of the uppermost suspension rope 8 through the thread head at the bottom, so that the floating ball 10 can be fixed at the top of the suspension rope 8, the device is convenient to assemble when in use, can be independently disassembled into a plurality of small parts, is more convenient to transport and can be easily suitable for different sampling depths, when in sampling, the main pull rope 7 by hand and slowly downwards put down the main sampling block 1, in the process, because the main sampling block 1 always has the gravity of pulling down, the bottom of the sealing plunger 11 at the bottom of the connecting frame 5 always clings to the inner side of the water inlet seat 3, so that no water can permeate into the main sampling block 1 when the main sampling block 1 is not submerged in water and does not reach the sampling depth, when the main sampling block 1 reaches the proper depth, the floating ball 10 can float on the water surface and can be tensioned by the suspension rope 8 to ensure that the main sampling block 1 can not continuously fall, at the moment, the main pull rope 7 is continuously loosened, the connecting frame 5 and the sealing plunger 11 at the bottom of the connecting frame can continuously slide downwards, so that an opening at the top of the water inlet seat 3 can leak, so that sewage can enter a water tank at the inner side of the top of the main sampling block 1, then the main pull rope 7 is pulled upwards, at the moment, the connecting frame 5 can drive the sealing plunger 11 to upwards move to block a fine hole in the middle of the water inlet seat 3 again, and the outward seepage of a sample can be avoided after the sampling is finished, but also can avoid the pollution of sewage of other depths to the sample, and the sampling is more accurate.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
