Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampling device technology, specifically relating to a sampling device for detecting heavy metals in wastewater. Background Technology
[0002] A sampling device is used to extract a certain amount of sample from a test object for further analysis and testing. Sampling devices play a crucial role in many fields such as quality control, environmental monitoring, and product inspection. Accurate sampling yields representative samples, which can then be analyzed and tested to assess the overall properties, quality, or safety of the material or environment. In wastewater heavy metal testing, wastewater samples need to be taken using a sampling device. However, existing sampling devices have a significant problem: their inlet pipes lack necessary protective structures. This allows dust and other impurities to easily enter the sampling container through the inlet pipe. If these impurities or dust are not treated before use, they will mix with the wastewater, adversely affecting the test data and leading to inaccurate results. Utility Model Content
[0003] The purpose of this invention is to provide a sampling device for heavy metal detection in wastewater, aiming to solve the problem of existing sampling devices. However, existing sampling devices have a significant problem: their inlet pipes lack necessary protective structures. This allows dust and other impurities to easily enter the sampling container through the inlet pipe. If these impurities or dust are not treated before use, they will mix with the wastewater, thus adversely affecting the detection data and leading to inaccurate results.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for heavy metal detection in wastewater, comprising a sampling container, a partition, an inlet pipe, and a drain pipe. A control valve is installed on the surface of the drain pipe. The inlet pipe and the drain pipe are connected at different heights to the two side walls of the sampling container. A baffle is provided on the front end face of the inlet pipe. A connecting rod is installed on the side wall of the sampling container. A first recess is rotatably connected to the end of the connecting rod. A rotating shaft is connected through the surface of the first recess. A fixing block is installed at the top of the sampling container. A threaded rod is threadedly connected through the surface of the fixing block. An installation block is rotatably connected to the end of the threaded rod. A second recess is rotatably connected to the end of the installation block.

[0021] 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. Example 1
[0022] Please see Figure 1-6 The present invention provides the following technical solution: a sampling device for heavy metal detection in wastewater, comprising a sampling container 1, a partition 2, an inlet pipe 3 and a drain pipe 4, control valves 5 installed on the surfaces of the inlet pipe 3 and the drain pipe 4, the inlet pipe 3 and the drain pipe 4 being connected at different heights to the two side walls of the sampling container 1, a baffle 6 provided on the front end face of the inlet pipe 3, a connecting rod 7 installed on the side wall of the sampling container 1, a first recess 8 rotatably connected to the end of the connecting rod 7, a rotating shaft 9 being connected through the surface of the first recess 8, a fixing block 14 installed at the top of the sampling container 1, a threaded rod 12 being threadedly connected through the surface of the fixing block 14, an installation block 13 rotatably connected to the end of the threaded rod 12, a second recess 10 rotatably connected to the end of the installation block 13, and a pin 11 being connected through the surface of the second recess 10.
[0023] In a preferred embodiment: the side wall of the first recess 8 is connected to one side of the inner side wall of the baffle 6, and the baffle 6 is rotatably connected to the connecting rod 7 through the first recess 8 and the rotating shaft 9.
[0024] In a preferred embodiment: the side wall of the second recess 10 is connected to the other side of the inner side wall of the baffle 6, and the baffle 6 is rotatably connected to the mounting block 13 through the second recess 10 and the pin 11.
[0025] In a preferred embodiment: the mounting block 13 forms a reciprocating threaded motion with the fixing block 14 via the threaded rod 12.
[0026] In a preferred embodiment, the inner wall of the baffle 6 is fitted to the end of the water inlet pipe 3.
[0027] In this embodiment, the sampling container 1 is cleverly divided into multiple internal spaces by the partition 2, achieving multi-layer sampling. The water inlet pipe 3 and the drain pipe 4 are installed at different heights on both sides of the sampling container 1, which facilitates both water inlet and drainage. The control valve 5 allows the operator to flexibly open the water inlet pipe 3 to allow water to enter according to sampling needs.
[0028] When operating the sampling device, the operator rotates the threaded rod 12, pushing it along the fixed block 14, which in turn moves the mounting block 13. The movement of the mounting block 13 drives the second recess 10, which rotates through the pin 11, causing the baffle 6 to tilt. At the same time, the other side of the baffle 6, through the action of the first recess 8 and the rotating shaft 9, drives the connecting rod 7 to rotate, ultimately causing the baffle 6 to open in a tilted state. Subsequently, the control valve 5 is rotated to open the water inlet pipe 3.
[0029] Next, the sampling container 1 is submerged in the sewage, and the sewage flows into the sampling container 1 through the opened inlet pipe 3, completing the water sample collection. Before this, the sampling container 1 is shielded by the baffle 6, which effectively prevents dust from falling into the inlet pipe 3, thus avoiding dust mixing with sewage and entering the sampling container 1, ensuring the purity of the collected water sample, and thereby improving the accuracy of heavy metal detection in sewage. Example 2
[0030] Please see Figure 1-6 The top of the sampling container 1 is connected to a fixing rod 15, and a protective cover 16 is connected to the surface of the fixing rod 15.
[0031] In a preferred embodiment, the fixing rod 15 is threadedly connected to the top of the sampling container 1.
[0032] In this embodiment, as described in Embodiment 1, when operating the sampling device, firstly, before the sampling container 1 is submerged in the sewage, the operator removes the fixing rod 15 and screws it onto the top of the sampling container 1. Then, the operator holds the fixing rod 15 and operates it through the protective cover 16 installed on it. The main function of the protective cover 16 is to protect the operator's hands; it effectively prevents water samples from splashing onto the hands during sampling, thereby eliminating potential safety hazards. This design not only improves operational safety but also ensures the smooth progress of the sampling process.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
