The working principle is as follows:

when the sampler works, firstly, the sampler can be conveniently placed in flowing sewage through the arrangement of the fixed plate 14, the probability that danger appears when a sampler stands on the river and soil collapses is reduced, when a sample needs to be taken, the sampler is placed at a position where water needs to be taken, the fixed plate 14 is held by a hand of the sampler, the pushing plate 15 is meshed with the bidirectional threaded rod 12, so that the pushing plate 15 can further drive the bidirectional threaded rod 12 to rotate, the sleeve frame 5 is sleeved on the bidirectional threaded rod 12 through the sliding block 13, the sleeve frame 5 is in sliding connection with the shell 1, it needs to be noted that the sleeve frame 5 is not in contact with the rotating rod 3 in the sliding process of the sleeve frame 5, and therefore, through the design, when water needs to be taken, only the pushing plate 15 needs to be pulled to move backwards, the sliding block 13 sleeved on the bidirectional threaded rod 12 in a threaded manner moves towards the direction away from each other, the first baffle 6 does not shield the sampling chamber 29 any more, the second baffle 7 does not shield the rotating wheel 19 any more, at this time, because the rotating wheel 19 is rotatably connected with the housing 1 through the rotating rod 3, when the water flow drives the rotating wheel 19 to rotate, the rotating rod 3 can be further driven to rotate, because the plurality of internal thread pipes 30 are rotatably connected with the rotating rod 3 through the rotating shaft 24, and the rotating shaft 24 fixedly sleeved with the internal thread pipes 30 at the front ends is positioned on the outer surface of the front part of the right side of the rotating rod 3, and the rotating shaft 24 fixedly sleeved with the internal thread pipes 30 at the rear ends is positioned on the outer surface of the rear part of the left side of the rotating rod 3, therefore, when the rotating rod 3 rotates clockwise, the plurality of internal thread pipes 30 can be driven to slide towards the central position inside the housing 1, because of the sealing plug 27 is arranged, when the internal thread pipes 30 drive the piston 28 to move towards the inside of the housing 1, it should be noted that, a plurality of cross-shaped water inlets are opened on the sealing plug 27, and the sealing plug 27 is made of rubber, so under the action of pressure difference, sewage enters between the sealing plug 27 and the piston 28 through the sealing plug 27, sewage entering into the sampling chamber 29 enters into the collecting chamber 22 through the communicating pipe 25, because the warning block 4 is fixedly sleeved on the rotating rod 3, the rotating angle of the rotating rod 3 can be judged by observing the warning block 4 on the water surface, so as to judge the sampling degree of the sampling operation, after the sampling is completed, the push plate 15 is pushed forward, when the push plate 15 moves forward, the two sliders 13 can be driven to move towards the side close to each other in the rotating process of the bidirectional threaded rod 12, because the first baffle 6 and the second baffle 7 are fixedly connected with the sleeve frame 5, therefore, the push plate 15 is pulled to move backward, when the two sliders 13 move towards the side close to each other, first baffle 6 can shelter from corresponding filter plate 9, and second baffle 7 can shelter from and rotate wheel 19 to can prevent that rivers from driving to rotate 19 filter plate 9 outside and rotate scraper blade 10 of connecting at the in-process of casing 1 rebound, thereby keep apart the water in the casing 1 outside, promote the accuracy of sampler fixed point water intaking

Meanwhile, when the internal thread pipe 30 moves in the sampling chamber 29 along with the rotation of the rotating rod 3, because the internal thread pipe 30 is in threaded sleeve connection with the screw rod 26, the movement of the internal thread pipe 30 can drive the screw rod 26 to rotate, thereby further driving the scraper 10 fixedly connected with the screw rod 26 to rotate, because the scraper 10 is in contact with the outer surface of the filter plate 9, the scraper 10 can scrape off the sludge on the outer surface of the filter plate 9 in the rotating process, the phenomenon that the filter screen is blocked can be effectively avoided, thereby facilitating the sampling operation of the sampler, and when the rotating wheel 19 drives the rotating rod 3 to rotate, because the rotating rod 3 is fixedly connected with the bump 21, therefore, the rotation of the rotating rod 3 can further drive the bump 21 to rotate, thereby effectively improving the sealing degree of the sealing gasket 20, when the sampler finishes sampling, and the shell 1 is taken out of water, promote catch plate 15 forward, catch plate 15 forward movement's in-process, can further drive and carry out spacingly with catch plate 15 fixed connection's spacing clamp 17 forward movement and to rocking bar 3, prevent that casing 1 from upwards moving the in-process, the effect of rivers to rotating wheel 19 appears, leads to rocking bar 3 pivoted phenomenon, has promoted the stability of sample in-process.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
