Description

Technical Field

[0001] This utility model relates to the field of water quality sampling equipment for wastewater treatment plants. Background Technology

[0002] In existing wastewater treatment processes, water quality testing is crucial. With increasing industrial and human activities, environmental pollution, especially water pollution, is on the rise. To better understand water resource information, it is essential to regularly sample and test water resources. Water samplers are indispensable equipment in this sampling process. Most existing water sampling devices rely on manual, on-site sampling, which is not conducive to assessing the overall water quality of a day's water samples. Furthermore, the timing of manual sampling is unpredictable, and the sample volume is inconsistent, resulting in mixed water samples that lack reference value. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the present invention, a wastewater treatment plant water quality sampling device includes a container 1. The upper end of the container 1 is provided with an inlet 11, the lower end of the container 1 is provided with a drain outlet 12, and the middle part of the container 1 is provided with a sampling port 13. Electric valves 14 are installed on the inlet 11, the drain outlet 12 and the sampling port 13. An overflow port 15 is also installed at the lower end of the container 1. The overflow port 15 is located below the sampling port 13. An overflow pipe 2 is provided on the outside of the container 1. The overflow pipe 2 and the overflow port 15 are connected by a first conduit 21. One end of the overflow pipe 2 is connected to a second conduit 22. A drain pipe 3 is connected between the second conduit 22 and the drain outlet 12.

[0021] An adjustment assembly 5 is installed on one side wall of container 1 near overflow pipe 2. The adjustment assembly 5 includes a fixed frame 501, which is fixedly connected to the outer wall of container 1 by welding. A slide rail 502 is installed on the middle of the outer side of the fixed frame 501. A lifting seat 503 is slidably assembled on the slide rail 502 along its length. A lead screw 504 is rotatably connected to the lower end of the fixed frame 501. The lead screw 504 is threadedly connected to the middle of the lifting seat 503. The outer end of the lifting seat 503 is fixedly connected to the outer wall of overflow pipe 2. A motor 505 for driving the lead screw 504 to rotate is installed on the upper end of the fixed frame 501.

[0022] The overflow pipe 2 is positioned between the inlet 11 and the sampling port 13; the first conduit 21 and the second conduit 22 are both soft conduits; the lifting seat 503 and the slide rail 502 are connected by a slider; a water level sensor 4 is installed on the inner wall of the container 1, and the water level sensor 4 is at the same horizontal position as the sampling port 13.

[0023] In this embodiment: Most existing water sampling devices rely on manual sampling at specific points, which is not conducive to detecting the overall water quality of a day's water sample. Furthermore, the timing of manual sampling is unpredictable, and the sample volume is inconsistent, resulting in mixed water samples that lack reference value. Therefore, this solution uses electric valves 14 to control the opening and closing of the inlet 11, outlet 12, and sampling port 13 in conjunction with the overflow pipe 2, ensuring a fixed water sampling volume. Secondly, a water level sensor 4 detects whether the water level is parallel to the sampling port and transmits the signal to regulate the opening and closing of the electric valves 14 on the inlet 11, outlet 12, and sampling port 13, achieving periodic quantitative sampling. In addition, the position and height of the overflow pipe 2 are adjusted using the adjusting component 5, thereby changing the distance between the overflow pipe and the sampling port. This allows for adjustment of the sampling volume according to sampling requirements.

[0024] Specifically, during normal water inflow and outflow, the electric valve 14 on the sampling port 13 is closed, while the electric valves 14 on the inlet 11 and outlet 12 are open. When water needs to be taken, the inlet 11, outlet 12, and sampling port 13 are all closed first. At this time, the water in container 1 flows out from the overflow pipe 2 until the water level is at the same level as the outlet of the overflow pipe 2. Then, the sampling port 13 is opened for sampling. After the water level is level with the sampling port and no water flows out, the sampling port 13 is closed to complete a single water sampling. After sampling, the inlet 11 and outlet 12 are opened again (in this scheme, the inflow rate of the inlet 11 is greater than the outflow rate of the outlet 12) until the water level rises again to the outlet of the overflow pipe 2, and the original normal water inflow and outflow state is restored.

[0025] This solution can be supplemented with an external controller and timer. The electric valve 14, water level sensor 4, and timer are all electrically connected to the controller. The timer periodically controls the opening and closing of the electric valve 14. For example, the above operation steps are controlled to cycle once every 2 hours to complete multiple samplings throughout the 24 hours of the day. When the water level sensor 4 detects that the water level is at the same level as the sampling port 13, the water level sensor 4 transmits a signal to the controller, which then controls the opening and closing of the electric valve 14.

[0026] In addition, before sampling, the position height of the overflow pipe 2 relative to the sampling port 13 is adjusted according to the sampling volume requirement. The motor 505 drives the lead screw 504 to rotate. The rotating lead screw 504 will drive the lifting seat 503 to move along the length of the slide rail, thus changing the position height of the overflow pipe 2. At this time, the sampling volume will also change.

[0027] Please refer to this carefully. Figures 1-3The adjustment component 5 also includes a size mark 506, which is engraved on one end of the outer wall of the fixed frame 501. A pointer 507 is connected to the upper end of the lifting seat 503, and the pointer 507 is located on one side of the lifting seat 503. The position height of the top of the pointer 507 is on the same horizontal plane as the position height of the drain outlet at the upper end of the overflow pipe 2.

[0028] In this embodiment: by engraving a size mark 506 on one end of the outer wall of the fixing frame 501, and using the pointer 507, it can be used to help observe and calculate the distance between the overflow pipe 2 and the sampling port 13, that is, the value of the sampling amount.

[0029] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
