Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, and in particular to a field sewage sampling device for environmental engineering. Background Technology

[0002] Environmental engineering is a branch of environmental science that mainly studies how to protect and rationally utilize natural resources, and uses scientific methods to solve increasingly serious environmental problems, improve environmental quality, and promote environmental protection and social development.

[0003] Water sampling is the process of detecting the concentration and composition of pollutants in water bodies. By analyzing water samples, we can understand the types and amounts of pollutants, which is a necessary step in environmental engineering for water quality treatment.

[0004] When environmental engineering uses sampling instruments to collect wastewater samples, it is sometimes necessary to sample in lakes. Since lakes contain a lot of impurities, filters are usually installed on the sampling instruments. However, in areas with a lot of impurities, the filters are prone to clogging, which affects the entry of wastewater and the sampling process, thus presenting certain shortcomings.

[0005] Therefore, an on-site wastewater sampling device for environmental engineering is provided to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned in the background art and to provide an on-site wastewater sampling device for environmental engineering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An on-site wastewater sampling device for environmental engineering includes a sampling shell, which is a hollow barrel with an open top, and further includes:

[0009] A filter cartridge is slidably connected inside the sampling shell, and the filter cartridge is provided with multiple sets of filter holes;

[0010] A floating plate is fixedly connected to the bottom of the filter cartridge;

[0011] The telescopic rod is fixedly connected to the sampling shell;

[0012] A partition is slidably connected to the top opening of the sampling shell, and the partition is fixedly connected to the telescopic end of the telescopic rod.

[0013] To facilitate stable sliding, preferably, the sampling shell is provided with a sliding groove, and the filter cylinder is provided with a protrusion that matches the sliding groove.

[0014] To facilitate the pulling out of the sampling shell, preferably, a bracket is fixedly connected to the sampling shell, and a pull rope is connected to the bracket.

[0015] Preferably, a mounting plate is fixedly connected to the bracket, and the pull rope is rotatably connected to the mounting plate.

[0016] Preferably, multiple sets of mounting blocks are fixedly connected to the sampling shell, and the telescopic rod is fixedly connected to the mounting blocks.

[0017] Preferably, multiple sets of mounting blocks 2 are fixedly connected to the sampling shell, and the bracket is fixedly connected to the mounting blocks 2.

[0018] To achieve a seal, preferably, a rubber strip is attached to the side of the partition.

[0019] To facilitate the discharge of wastewater, preferably, the sampling shell is connected to an outlet pipe with a valve.

[0020] Compared with the prior art, this utility model provides an on-site wastewater sampling device for environmental engineering, which has the following beneficial effects:

[0021] This invention, through the cooperation of the filter cartridge and the floating plate, allows the floating plate to move upward continuously by buoyancy during sewage sampling. This causes the filter holes on the side of the filter cartridge to come into contact with the outside environment, thereby continuously increasing the number of filter holes in contact with the external sewage. This allows sewage to continuously enter the sampling shell, avoiding blockages that would slow down the sewage entry and increasing sampling efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example:

[0030] Reference Figure 1-5 An on-site wastewater sampling device for environmental engineering includes a sampling shell 1, which is a hollow barrel with an open top. It also includes: a filter cylinder 3 slidably connected inside the sampling shell 1, with multiple sets of filter holes on the filter cylinder 3; a floating plate 5 fixedly connected to the bottom of the filter cylinder 3; a telescopic rod 4 fixedly connected to the sampling shell 1; and a partition 6 slidably connected to the top opening of the sampling shell 1, with the partition 6 fixedly connected to the telescopic end of the telescopic rod 4. A sliding groove 2 is provided inside the sampling shell 1, and the filter cylinder 3 has protrusions that match the sliding groove 2. A bracket 104 is fixedly connected, a pull rope 106 is connected to the bracket 104, and an mounting plate 105 is fixedly connected to the bracket 104. The pull rope 106 is rotatably connected to the mounting plate 105. Multiple sets of mounting blocks 102 are fixedly connected to the sampling shell 1. The telescopic rod 4 is fixedly connected to the mounting blocks 102. Multiple sets of mounting blocks 103 are fixedly connected to the sampling shell 1. The bracket 104 is fixedly connected to the mounting blocks 103. A rubber strip 7 is connected to the side of the partition 6. A liquid outlet pipe 101 with a valve is connected to the sampling shell 1.

[0031] like Figure 5 As shown, filter cylinder 3 is a hollow barrel with filter holes on the top and sides. In its initial state, it appears as follows: Figure 2As shown, the side of the sampling shell 1 is attached to the inner wall, preventing water from entering through the side filter cartridge 3. The bottom of the sampling shell 1 has a counterweight. When the sampling shell 1 is placed on water, it will sink vertically under the influence of the counterweight. The depth of the sinking is determined by pulling the rope 106. Once the appropriate depth is reached, the telescopic rod 4 can be activated. The extension of the telescopic rod 4 will cause the partition 6 to move upward, thus opening the top opening of the sampling shell 1. At this point, external sewage will enter the sampling shell 1 through the opening and then directly enter the bottom of the sampling shell 1 through the filter holes at the top of the filter cartridge 3. At this point, the filter holes can play a filtering role. Since environmental engineering mainly collects sewage and tests its components, it generally does not analyze and test large particulate impurities in the water. Therefore, the sewage that has passed the coarse filtration will quickly enter the sampling shell 1. Then the water will come into contact with the float plate 5, and the float plate 5 will float on the sewage, which will cause the filter cylinder 3 to move slowly upward. Subsequently, the filter holes on the side of the filter cylinder 3 will come into contact with the outside, thus allowing more channels for sewage from the outside to enter the sampling shell 1. This can avoid the situation where the filter holes at the top are blocked and the sewage entry speed slows down.

[0032] Specifically, a water level sensor can be installed inside the sampling shell 1. After obtaining wastewater at a suitable water level, the telescopic end of the telescopic rod 4 can be retracted, causing the partition 6 to re-seal the top of the sampling shell 1 and squeezing the filter cartridge 3 back into the sampling shell 1.

[0033] Finally, the sampling shell 1 can be pulled out by pulling rope 106, and the sewage can be taken out by opening the liquid outlet pipe 101 for testing.

[0034] This invention, through the cooperation of the filter cartridge 3 and the floating plate 5, allows the floating plate 5 to move upward continuously by buoyancy during sewage sampling. This causes the filter holes on the side of the filter cartridge 3 to come into contact with the outside environment, thereby continuously increasing the number of filter holes in contact with the external sewage. This allows sewage to continuously enter the sampling shell 1, avoiding blockages that would slow down the sewage entry and increasing sampling efficiency.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
