[0027] In this embodiment, a transverse groove 6 is further provided on one side of the installation box 214 close to the opening and closing cover 23, and an L-shaped guide rod 7 is fixedly connected to the top of the opening and closing cover 23. The upper end of the L-shaped guide rod 7 extends to the interior of the installation box 214 through the transverse groove 6, and the guide rod 7 is slidably arranged with the transverse groove 6.

[0028] The supporting seat 3 is fixedly connected to the installation box 214 through the connecting frame 11. A placement groove 302 is opened on the top of the supporting seat 3. The sampling bottle 4 is placed in the placement groove 302. A tightening screw 301 is threadedly connected on the side wall of the supporting seat 3. The end of the tightening screw 301 extends into the placement groove 302 and presses against the outer wall of the sampling bottle 4 to prevent the sampling bottle 4 from falling.

[0029] The main body of the arc support frame 1 is made of plastic, and the outer surface of the arc support frame 1 is covered with an aluminum alloy shell for increasing strength, which can ensure the strength of the arc support frame 1 and reduce the weight of the arc support frame 1, making it lighter and more durable. A traction rope 10 is fixedly connected to the top of the arc support, and the traction rope 10 is fixed to the wellhead of the sewage well.

[0030] An iron hook is installed at the bottom of the arc-shaped support frame 1, and a guide rope 8 is connected to the iron hook. A through hole is opened in the center of the gravity ball 24, and the guide rope 8 passes through the gravity ball 24 through the through hole. A pull rope 9 is also fixedly connected to the top of the gravity ball 24. By releasing the pull rope 9 or tightening the pull rope 9, the gravity ball 24 can descend or rise along the guide rope 8. At the same time, the gravity ball 24 squeezes the push rod 212 when sliding up and down along the guide rope 8.

[0031] When the device is used for sewage sampling, S1, firstly, the sampling bottle 4 is placed on the supporting seat 3, and then the tightening screw 301 is tightened to tighten the sampling bottle 4.

[0032] S2. Adjust the positions of the plugging component 2 and the sampling bottle 4 according to the sampling depth, and then fix the plugging component 2 and the arc-shaped support frame 1 with a screw.

[0033] S3. The arc-shaped support frame 1 with the plugging assembly 2 and the sampling bottle 4 installed is hoisted into the medical sewage well as a whole, and the arc-shaped support frame 1 is fixed to the wellhead by a traction rope 10. At this time, the gravity ball 24 is placed on the top of the arc-shaped support frame 1.

[0034] S4, release the pull rope 9, so that the gravity ball 24 slides from top to bottom along the guide rope 8, and sequentially abuts against the abutment block 215 on each blocking component 2. At this time, the abutment block 215 is squeezed and pushes the slider 213 to squeeze the spring to slide through the push rod 212. At the same time, the locking rod 217 slides clockwise along the locking ring groove 216 and is stuck in the position of the guide angle 5 2165. When the slider 213 slides, it drives the tooth plate 221 to move synchronously. The tooth plate 221 is meshed with the pinion 222 to bring The movable shaft 225 rotates, thereby causing the large gear 223 to rotate along with the shaft 225. The large gear 223 rotates and meshes with the rack 224 on the opening and closing cover 23, thereby driving the opening and closing cover 23 and the toothed plate 221 to move in the opposite direction, so that the water inlet 231 of the opening and closing cover 23 moves to the top of the sampling bottle 4. At this time, the sampling bottle 4 is connected to the sewage well through the water inlet 231, and the sampling bottle 4 starts to sample. When the gravity ball 24 reaches the lowest point of the guide rope 8, all the opening and closing covers 23 are opened.

[0035] S5. After sampling for a period of time, the sampling bottles 4 at different depths have completed sampling. At this time, the pull rope 9 is pulled upward to move the gravity ball 24 from bottom to top, so that the gravity ball 24 squeezes the abutment block 215 again during the rising process. The abutment block 215 is squeezed and pushes the push rod 212 again, so that the push rod 212 pushes the slider 213 to slide, and the locking rod 217 continues to slide clockwise along the locking ring groove 216, and finally slides to the position of the guide angle 2162 and is stuck there, that is, the locking rod 217 Return to the original position; when the slider 213 slides, the toothed plate 221 moves synchronously with the slider 213 and drives the small gear 222 to rotate. The small gear 222 drives the large gear 223 to rotate through the rotating shaft 225, so that the large gear 223 drives the opening and closing cover 23 and the toothed plate 221 to move in the opposite direction. The water inlet 231 of the opening and closing cover 23 is disconnected from the inlet of the sampling bottle 4, so that the bottle mouth of the sampling bottle 4 is closed. When the gravity ball 24 reaches the top of the guide rope 8, all the opening and closing covers 23 are closed.

[0036] S6. The staff takes out the arc-shaped support frame 1 as a whole from the medical sewage well, and removes the sampling bottles 4 respectively.

[0037] The present invention utilizes an arc-shaped support frame, a gravity ball, and multiple plugging components to simultaneously send sampling bottles into corresponding positions of the medical sewage well according to the depth of sampling required, and then samples sewage at different depths are separately sampled. After the sampling is completed, the sampling bottles can be stably disconnected from the sewage to ensure that the sewage in each sampling bottle will not be cross-contaminated, and then the sampling bottles can be taken out of the sewage well together, which is convenient and quick.

[0038] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
