Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment sampling, and more specifically, to a sewage treatment sampling device. Background Art

[0002] In the existing technology, there are some problems in the operation of sewage treatment sampling devices. First, the existing sewage treatment sampling devices usually use ropes to connect the sampling barrel to lower it for sampling. This operation method requires the sampling barrel to be tilted to the water surface before the water can be sampled. However, this method may cause the tilt angle of the sampling barrel to be inaccurate, affecting the accuracy of the sampling results. At the same time, the process of tilting the sampling barrel requires a certain amount of time and skills, which makes the sampling process inefficient and brings adverse effects.

[0003] Secondly, some of the existing technologies use mechanized structures for sampling. However, the connection and disassembly operations between the sampling tube and the connecting frame are usually cumbersome. The sampling tube and the connecting frame may need to be fixed by bolts, screws or other connecting parts. The installation and disassembly of these connecting parts require time and effort. Moreover, special tools may need to be used during the connection and disassembly process, which increases the complexity of the operation. This cumbersome operation causes the sampling equipment to respond slowly, and sampling cannot be performed quickly, which brings adverse effects.

[0004] In addition, in the prior art, the sampling port of the sampling tube needs to be opened before sampling can be performed. However, during the sampling process, water is easily overflowed from the sampling port when the sampling port is opened. The overflowed water may affect the normal operation of the equipment. This overflow phenomenon has an adverse effect on the sampling process. Utility Model Content

[0035] A matching sleeve 24 is sleeved on the outer side of the fixing rod 20 , and a matching groove 25 is opened on the side wall of the matching sleeve 24 . The position of the matching groove 25 corresponds to the position of the clamping plate 19 .

[0036] A rotating sleeve 26 is sleeved on the outer side of the fixing rod 20 , a supporting rod 27 is arranged on one side of the rotating sleeve 26 , and a through hole 28 is opened on the fixing plate 21 , and the diameter of the through hole 28 is slightly larger than the diameter of the supporting rod 27 .

[0037] A second spring 29 is sleeved on the outer side of the support rod 27 , and the top end of the second spring 29 is in contact with the fixing plate 21 .

[0038] A first spring 30 is disposed on the outer side of the fixing rod 20 , and the other end of the first spring 30 is connected to the clamping plate 19 .

[0039] Handles 31 are provided on both sides of the matching sleeve 24 , and the handles 31 are fixedly connected to the top of the matching sleeve 24 .

[0040] More specifically, before sampling, first align the mounting holes on the connecting plate 8 and the connecting frame 7, and place the sampling tube 5 under the connecting frame 7, then place the fixing sleeve 22 under the connecting plate 8, and then insert the matching sleeve 24 and the fixing rod 20 from the upper end surface of the connecting frame 7 into the fixing sleeve 22. During the insertion process, the clamping plate 19 is squeezed by the side wall of the mounting hole, and then the clamping plate 19 will approach the inside and compress the first spring 30.

When the second spring 29 is compressed to the limit, the handle 31 will drive the matching sleeve 24 and the fixed rod 20 to separate from the fixed sleeve 22, thereby completing the rapid disassembly of the sampling tube 5.

[0041] In summary, when the overall equipment is in use or running: when the equipment needs to be used for sampling, first open the hydraulic cylinder 2 installed on the inner side of the support frame 4, and the hydraulic cylinder 2 drives the connecting frame 7 to descend through the hydraulic rod 3 connected to the output end, and at the same time, the telescopic rod 18 will be synchronously extended from the telescopic sleeve 17. The setting of the telescopic rod 18 and the telescopic sleeve 17 can ensure the stable descent of the connecting frame 7 and the sampling tube 5. When the bottom end of the sampling tube 5 contacts the baffle 16, the sampling tube 5 continues to descend and will push the baffle 16 to slide in the fixed frame 15. At the same time, the baffle 16 will compress the push spring 11 set on one side, and the tension spring 9 connected to one side of the first elastic plate 13 will be gradually reset, and then the second elastic plate 14 will first contact the push rod 12 set at the bottom end of the fixed frame 15, and then the push rod 12 will push the second elastic plate 16 set on the baffle 16 The plate 14 is pushed open, so that the gap between the second elastic plate 14 is opened. At the same time, the second elastic plate 14 will push open the first elastic plate 13 set in the sampling tube 5, so that the gap between the first elastic plate 13 is opened, and then the water in the delivery pipe 1 will enter the sampling tube 5 through the gap between the water inlet groove 10 and the first elastic plate 13 and the second elastic plate 14. After the sampling is completed, the hydraulic cylinder 2 drives the hydraulic rod 3 and the connecting frame 7 to rise to complete the sampling work, and then the push spring 11 loses the limit of the sampling tube 5 and pushes the baffle 16 to reset. At the same time, the second elastic plate 14 will drive the tension spring 9 to stretch, so that the second elastic plate 14 is firmly on the inside of the baffle 16. The whole process can effectively prevent water leakage, and in normal use, the second elastic plate 14 will be tightened due to the tension of the tension spring 9 to prevent it from being pushed open by water.

[0042] Before sampling, first align the mounting holes on the connecting plate 8 and the connecting frame 7, and place the sampling tube 5 under the connecting frame 7, then place the fixing sleeve 22 under the connecting plate 8, and then insert the matching sleeve 24 and the fixing rod 20 from the upper end surface of the connecting frame 7 into the fixing sleeve 22. During the insertion process, the clamping plate 19 is squeezed by the side wall of the mounting hole, and then the clamping plate 19 will approach the inside and compress the first spring 30. When it is fully inserted into the fixing sleeve 22, the first spring 30 will push the clamping plate 19 to reset, so that the clamping plate 19 is engaged in the threaded groove 23, so as to realize the quick connection between the sampling tube 5 and the connecting frame 7. At the same time, due to the support of the support rod 27 on the fixing plate 21, the sampling tube 5 and the connecting frame 7 are connected. The connection between them is more stable. After sampling is completed, the rotating sleeve 26 is rotated in the corresponding direction first. When the position of the support rod 27 corresponds to the position of the through hole 28, the handle 31 is pulled. The handle 31 drives the matching sleeve 24 and the rotating sleeve 26 to move, and then the support rod 27 passes through the through hole 28. At the same time, the second spring 29 sleeved on the outside of the support rod 27 will be squeezed by the fixed plate 21, and then the matching sleeve 24 will drive the matching groove 25 to squeeze the outside of the card plate 19, so that the card plate 19 presses the first spring 30 again and collects it into the matching groove 25. When the second spring 29 is compressed to the limit, the handle 31 will drive the matching sleeve 24 and the fixed rod 20 to separate from the fixed sleeve 22 together, thereby completing the rapid disassembly of the sampling tube 5.
