Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, and more specifically, to a sampling device for wastewater detection. Background Technology

[0002] Wastewater testing refers to the process of monitoring and analyzing various pollutants in wastewater, which may include organic matter, inorganic matter, heavy metals, microorganisms, etc. The purpose of wastewater testing is to ensure that wastewater discharge complies with environmental regulations and standards, as well as to protect water quality and the health of ecosystems. However, traditional wastewater testing sampling devices have some drawbacks that affect daily use.

[0003] The primary problem is that traditional wastewater sampling devices cannot adjust the sampling height. Wastewater often has different compositions at different depths. For example, the surface layer may contain light impurities such as grease and fallen leaves, the middle layer is a relatively uniform mixed wastewater, and the bottom layer may contain a large amount of sludge and heavy metals. If the sampling device cannot adjust the height, it can only be sampled at a fixed depth. The sample obtained can only reflect the wastewater condition at that depth and cannot represent the true condition of the overall wastewater.

[0004] More significantly, traditional wastewater testing sampling devices lack independent sample compartments. Without these compartments, the collected wastewater samples are often directly exposed to the external environment or in direct contact with other components of the sampling device. Dust and impurities from the external environment can easily fall into the sample, and residual wastewater from previous samplings or other contaminants on the device can also contaminate the current sample. This can lead to biased test results, failing to accurately reflect the actual condition of the wastewater and affecting the assessment of the degree of pollution and the development of subsequent treatment plans. In wastewater testing, it is sometimes necessary to perform stratified sampling of wastewater at different depths to comprehensively understand its composition distribution. However, sampling devices lacking independent sample compartments typically only allow for single sampling. Stratified sampling requires multiple samplings and container changes, which is cumbersome and inefficient. Furthermore, when multiple tests are required on the same wastewater sample, the lack of separate sample compartments forces samples to be stored in a single container. When separating samples for different tests, cross-contamination can easily occur, affecting the accuracy of the test results.

[0005] Crucially, traditional wastewater sampling devices lack anti-clogging designs. Wastewater often contains a large amount of suspended particulate matter, fibrous impurities, silt, etc. Without anti-clogging designs, the sampling port, pipes, and storage components of the sampling device are easily clogged by these impurities. Once a blockage occurs, the sampling process is forced to stop, and operators need to spend a lot of time clearing the blockage, such as disassembling pipes and unblocking the sampling port. In scenarios that require continuous or batch sampling, such interruptions will severely slow down the overall work progress and lead to a significant decrease in sampling efficiency.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a sampling device for wastewater detection, which has the following beneficial effects:

[0018] 1. Through the close cooperation between the support base, hydraulic cylinder, piston rod, support rod and hydraulic pump, a complete height adjustment device is formed. The device for adjusting the sampling height can flexibly collect sewage samples at different depths according to the testing needs, so as to comprehensively reflect the overall condition of the sewage. Operators can adjust the height of the sampling device to a comfortable operating position according to their own height and the terrain of the sampling environment, reducing uncomfortable postures such as bending over and tiptoeing, and reducing labor intensity.

[0019] 2. Through the close cooperation between the box, partitions, sampling bottles, drawers, solenoid valves and nozzles, a complete independent storage device is formed. This device allows operators to quickly disassemble or install the sample chamber from the device. After sampling, the sample chamber can be transferred as a whole without direct contact with sewage, reducing the chance of contact with harmful substances in sewage and lowering operational risks.

The sampling process will not be frequently interrupted due to blockage. Operators do not need to spend a lot of time cleaning blockages. Sampling work can be completed continuously and smoothly. In scenarios that require continuous or batch sampling, it can significantly speed up the overall work progress and ensure that sufficient samples are obtained at the optimal sampling time. It can reduce the residue of impurities on the inner wall of the sampling device, reduce the possibility of cross-contamination of samples in the next sampling, and at the same time, ensure that the sample volume is sufficient and the composition is normal, so that subsequent laboratory testing can be carried out smoothly and avoid the need for resampling due to sample problems, thereby reducing testing costs and time costs.

The sampling pipe 18 is fixedly connected to the water outlet pipe 16 and the water pump 19, respectively. The water pump 19 is fixedly connected to the solenoid valve 6 and the cabinet 1, respectively.

[0033] In a further embodiment of this application, the pipes at the output end of the solenoid valve 6 are each connected to different channels within the solenoid valve 6, ensuring that different channels of the solenoid valve 6 are opened and closed during sampling, so that the sampling results are not mixed and cause interference.

[0035] In a further embodiment of this application, the outlet pipe 16 is provided with a baffle 22. The baffle 22 is located on one side of the sampling pipe 18 near the end of the outlet pipe 16. The baffle 22 can introduce a portion of sewage without large-volume dirt into the sampling pipe 18.

The solenoid valve 6 is opened to the valve port of the sampling bottle 4 that needs to hold the sample. At the same time, the water pump 19 is started. When the sewage passes through the water outlet pipe 17, large-volume dirt will be discharged from the water outlet pipe 16, while the baffle 22 can introduce some sewage without large-volume dirt into the sampling pipe 18. The sewage is drawn by the water pump 19, passes through the filter screen 26 and enters the solenoid valve 6, and enters the sampling bottle 4 through the nozzle 7 to complete the sampling.

[0039] More specifically, when changing the sampling height or location, the valve port of the solenoid valve 6 corresponding to the sampling bottle 4 that has been sampled is closed, and other valve ports are opened for sampling and collection, so that each sampling will not mix and interfere with each other. When it is necessary to take out the sampling bottle 4, the drawer 5 is pulled out from the box 2, and the sampling bottle 4 can be taken out directly from the partition plate 3.

[0040] In summary, during the use or operation of the overall equipment: the cabinet 1 is moved to the sampling position by using the handle 20 and roller 21; the adjusting nut 24 and support pad 25 are rotated to make the support pad 25 touch the ground, and the position of the support pad 25 and adjusting column 23 is locked by the adjusting nut 24 to complete the fixation; the hydraulic pump 12 is started to make the piston rod 10 extend and retract in the hydraulic cylinder 9, so that the support rod 11 rotates around the support base 8, so that the water inlet pipe 17 is immersed in the water surface to reach the required working height; the motor 14 is started to make the turbine 15 rotate, so that the sewage enters the housing 13 from the water inlet pipe 17 and is discharged through the water outlet pipe 16; the solenoid valve 6 is opened to the valve port of the sampling bottle 4 that needs to hold the sample; at the same time, the water pump 19 is started. When the sewage passes through the water outlet pipe 17, large-volume dirt will be discharged from the water outlet pipe 16, while the baffle 22 can introduce some sewage without large-volume dirt into the sampling pipe 18; the sewage is drawn by the water pump 19, passes through the filter screen 26 and enters the solenoid valve 6, and enters the sampling bottle 4 through the nozzle 7 to complete the sampling.

[0041] When changing the sampling height or location, close the valve port of the solenoid valve 6 corresponding to the sampling bottle 4 that has been sampled, and open other valve ports to collect samples, so that each sampling will not mix and interfere with each other. When it is necessary to take out the sampling bottle 4, pull the drawer 5 out of the box 2, and the sampling bottle 4 can be taken out directly from the partition plate 3.
