Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 3, a water sampling device for sewage treatment comprises a cylinder 1, wherein the cylinder 1 is made of a transparent plastic plate, the top of the cylinder 1 is connected with a top seat 2 by glue, and the bottom of the cylinder 1 is connected with a base 9 by glue. The top base 2 is connected with the drain pipe 3 and the guide pipe 4 through surface glue, the top base 2 is run through to the bottom of the drain pipe 3, the drain pipe 3 is provided with four, the four drain pipes 3 are uniformly distributed in an annular shape by taking the guide pipe 4 as the center, the four drain pipes 3 are adopted to replace the traditional single drain pipe, and the phenomenon that the cylinder 1 cannot drain water due to the blockage of the single drain pipe 3 is avoided. 4 clearance fit pull rods 5 of guiding tube, 5 tops of pull rods stretch out 4 back glue of guiding tube and connect stopper 6, stopper 6 fixed connection pull ring 7, and pull ring 7 is tied and is hung rigidity rope 8.
Set for when stopper 6 and guide tube 4 looks butt, leather cup 13 breaks away from conical surface hole 901, and leather cup 13 hangs in the filter screen 10 top, and stopper 6 blocks counter weight 12 and leather cup 13 and contacts with filter screen 10, avoids the filter screen to receive gravity extrusion, is favorable to maintaining the shape of filter screen 10, intercepts great solid pollutant (like pasture and water, solid domestic waste etc.) in the sewage through filter screen 10, and the water sample of gathering can put into later stage experimental measurement more conveniently.
The lower surface of the top seat 2 is connected with a threaded pipe 14 through a bolt, the pull rod 5 is provided with an external thread block 15, the external thread block 15 and the pull rod 5 are integrally formed, the external thread block 15 is matched with the threaded pipe 14, and when the external thread block 15 is screwed with the threaded pipe 14, the leather cup 13 is embedded into the conical hole 901. 2 upper surfaces of footstock are equipped with rather than integrated into one piece's two upright pieces 16, and upright piece 16 is run through at the both ends of handle 17, and the both ends of handle 17 respectively with two upright 16 clearance fits, through pulling handle 17, conveniently have enough to meet the need the water sample.
The working principle is as follows: because the mass of the counterweight 12 is far greater than that of the barrel 1, when the counterweight 12 and the barrel 1 descend together in a water body, the descending speed of the counterweight 12 and the pull rod 5 as a whole is higher than that of the barrel 1, the conical hole 901 is in an open state in the descending process, the water body enters the barrel 1 from the conical hole 901 and flows out of the drain pipe 3, and the barrel 1 can be thrown into a water layer with a specified depth by the rigid rope 8.
And after the barrel body 1 reaches the designated depth, the water body at the designated depth fills the whole barrel body 1. Pulling up the rigid rope 8, the rigid rope 8 enables the balance weight 12 to move upwards by pulling the pull rod 5, and the balance weight 12 and the leather cup 13 close the conical hole 901, so that a water sample is not introduced into the bottom of the barrel 1 any more. Because barrel 1 is the state of filling with the water sample, so the water sample can not follow drain pipe 3 and flow into barrel 1, has avoided the water sample to take place to mix.
After the barrel 1 is lifted out of the water, the limiting block 6 is rotated, so that the limiting block 6 drives the external thread block 15 to be screwed with the threaded pipe 14, the balance weight 12 continues to move upwards for a short distance, namely, the balance weight 12 is prevented from moving downwards through the thread fit of the external thread block 15 and the threaded pipe 14, the leather cup 13 is reliably plugged on the base 9, the water sample leakage is avoided, the balance weight 12 is fixed, and the sampling is completed.
