[0002] Wastewater testing is one of the important tasks in the field of environmental protection. It is the monitoring and analysis of the concentration, type and change trend of pollutants in wastewater. With the continuous development of industrialization, urbanization and human activities, the amount of wastewater generated and discharged has increased year by year, and its impact on the environment has received more and more attention. It can reflect the degree of pollution and harm of wastewater, and provide a scientific basis for environmental protection and governance. For this purpose, a portable wastewater testing sampling device is needed.

[0003] Using a portable wastewater sampling device to collect water samples on site is the first step in quality control, which requires that the sampling be disturbed as little as possible to ensure the accuracy of the test results. At present, various environmental monitoring departments generally use permanent water scoops and water bottles as sampling tools, and extend the water bottles into the water body for sampling and collection.

[0004] However, using this sampling tool to collect water will cause residues such as heavy metals or grease floating on the water surface to enter the container first and affect the test results. At the same time, when collecting wastewater from rivers, lakes and other places, environmental factors such as the slippery river bank make sampling difficult and easily affect the safety of the sampling personnel. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a portable wastewater testing sampling device, which aims to improve the existing technology of using traditional sampling tools to collect water, which will cause heavy metals or oil residues floating on the water surface to enter the container first and affect the detection results. At the same time, in the process of collecting wastewater from rivers, lakes and other places, environmental factors make sampling difficult and easily affect the safety of sampling personnel.

[0007] Furthermore, an adjusting rod is fixedly connected to the lower surface of the bottom plate, a connecting rod is rotatably connected to the bottom of the adjusting rod, and a clamping joint is fixedly connected to one end of the connecting rod.

[0008] Furthermore, the outer wall of the connecting rod is fixedly connected with a positioning shaft, and one end of the positioning shaft is fixedly connected with the second housing.

[0009] Furthermore, the outer wall of the second shell is slidably connected to the inner wall of the first shell, and a concave hole 1 is provided inside both the first shell and the second shell.

[0010] Furthermore, a sampling bottle is fixedly connected to a lower surface of the shell, and a water inlet is opened inside the sampling bottle.

[0011] Furthermore, a rubber sealing ring is fixedly connected to the lower surface of the sampling bottle, a sheet magnet is fixedly connected to the lower surface of the rubber sealing ring, and a conical iron block is fixedly connected to the lower surface of the sheet magnet.

[0012] Furthermore, a second groove is provided inside the sampling bottle, a filter plate is slidably connected to the inner wall of the sampling bottle, and a second concave hole is provided inside the filter plate.

[0013] Furthermore, a pull rod is fixedly connected to the outer wall of the filter plate, and a connecting block is fixedly connected to the outer wall of the pull rod.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a portable wastewater detection sampling device, comprising a handle 1, a housing 2 is fixedly connected to the lower surface of the handle 1, a groove 22 is provided inside the handle 1, a pressure block 3 is slidably connected to the inner wall of the handle 1, a vertical rod 14 is fixedly connected to the lower surface of the pressure block 3, a spring 15 is sleeved on the outer wall of the vertical rod 14, one end of the spring 15 is fixedly connected to the lower surface of the pressure block 3, and the other end of the spring 15 is fixedly connected to a bottom plate 16, the outer wall of the bottom plate 16 is slidably connected to the inner wall of the handle 1, and an adjusting rod 17 is fixedly connected to the lower surface of the bottom plate 16, a connecting rod 18 is rotatably connected to the bottom of the adjusting rod 17, one end of the connecting rod 18 is fixedly connected to a card joint 20, and the outer wall of the connecting rod 18 is fixedly connected to a positioning shaft 19, one end of the positioning shaft 19 is fixedly connected to a housing 21, and the outer wall of the housing 21 is slidably connected to the inner wall of the housing 2, and a recessed hole 4 is provided inside both the housing 2 and the housing 2.

[0024] Specifically, the spring 15 can play a buffering and resetting role during the pressing process of the pressure block 3, thereby preventing the pressure block 3 from being pressed too deeply and unable to be reset; and when adjusting according to the sampling depth, the clamping joint 20 can be embedded in the concave hole 4 of the shell 21, and when the handle 1 is pulled to drive the adjustment rod 17 to move downward, the positioning shaft 19 is connected to the shell 21, so that the shell 21 slides inside the shell 2, and the clamping joint 20 is engaged in a concave hole 4 in the shell 2 to achieve telescopic adjustment of different lengths, thereby being able to sample water at different depths.

[0025] Reference Figure 1 and Figure 2A sampling bottle 5 is fixedly connected to the lower surface of the outer shell 2, a water inlet 6 is provided inside the sampling bottle 5, a rubber sealing ring 7 is fixedly connected to the lower surface of the sampling bottle 5, a sheet magnet 8 is fixedly connected to the lower surface of the rubber sealing ring 7, a conical iron block 9 is fixedly connected to the lower surface of the sheet magnet 8, a groove 23 is provided inside the sampling bottle 5, a filter plate 10 is slidably connected to the inner wall of the sampling bottle 5, a recessed hole 2 13 is provided inside the filter plate 10, a pull rod 11 is fixedly connected to the outer wall of the filter plate 10, and a connecting block 12 is fixedly connected to the outer wall of the pull rod 11.

[0026] Specifically, by setting the rubber sealing ring 7, the bottom of the sampling bottle 5 in the device can be effectively prevented from leaking, and it has a good sealing effect; at the same time, a filter plate 10 is arranged on the inner wall of the upper end of the sampling bottle 5, which can filter out the oil film and other residues on the surface of the wastewater, and effectively reduce the influence of the oil film and other residues on the surface of the oil-containing wastewater on the water body measurement results; a sheet magnet 8 is arranged at the bottom of the sampling bottle 5, and a conical iron block 9 is adsorbed on the sheet magnet 8. When taking water, it is not easy to destroy the hydrological state of the water body and cause distortion of the water sample, which is easy to carry; at the same time, the conical iron block 9 can act as a counterweight, which can effectively overcome the resistance of the water and make sampling more labor-saving.

[0027] Working principle: When it is necessary to sample the wastewater, the filter plate 10 is connected to the pull rod 11 by inserting the connecting block 12 on the pull rod 11 into the concave hole 13 in the filter plate 10, and then the pull rod 11 is pushed to slide the installed filter plate 10 along the groove 23 in the sampling bottle 5 so that the filter plate 10 is completely embedded in the sampling bottle 5. Then, the handle 1 is held to press the pressing block 3 downward to make the pressing block 3 slide downward in the groove 1 22. Under the connection of the vertical rod 14, the adjusting rod 17 under the bottom plate 16 is driven to move downward. At the same time, the connecting rod 18 connected to the adjusting rod 17 swings and adjusts according to the sampling depth so that the card joint 20 can be embedded in the concave hole 1 4 in the shell 1 2 and the shell 2 21. At this time, the handle 1 is held to insert the device into the water, and the water enters from the water inlet 6 in the sampling bottle 5. The water is collected into the sampling bottle 5 after being filtered by the filter plate 10, and then the handle 1 is pulled to take the device out of the water, and the sampling is completed.
