Description

Technical Field

[0001] The utility model relates to the technical field of wastewater detection devices, in particular to a wastewater sampling and detection sample collector. Background Art

[0002] Wastewater sampling refers to the process of collecting water samples from wastewater discharge sources or treatment facilities for water quality analysis. Wastewater sampling is an important part of environmental monitoring and water quality management. It helps to assess the degree of wastewater pollution, monitor treatment effects, and ensure that wastewater discharge complies with relevant standards and regulatory requirements.

[0003] At present, when sampling wastewater, the wastewater is collected by a collector and the wastewater samples are tested by a testing device. The current collector is generally a syringe. When the existing wastewater sampling and testing sample collector is in use, the guide slide is pushed by a spring to move, and the guide slide drives the syringe barrel to move to the left, thereby pushing the syringe to the left. When installing sampling bottles of different lengths, the sampling bottles are clamped by controlling the compression spring to meet the installation of sampling bottles of different sizes, which increases the flexibility of the device. When sampling or discharging wastewater, it is necessary to press or pull the pressing rod set in the syringe. However, when using the existing syringe, the operator may mistakenly press or pull the pressing rod due to human factors, which may result in inaccurate sampling volume, affecting the accuracy and reliability of the sampling data, and affecting the correct assessment of the wastewater quality.

[0004] Therefore, it is necessary to provide a new wastewater sampling and detection sample collector to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a wastewater sampling and detection sample collector.

[0006] The utility model provides a wastewater sampling and testing sample collector comprising a housing and a pressing rod, wherein the pressing rod is movably connected to the inner wall of the housing, and both sides of the pressing rod are fixedly connected to a limiting device;

[0007] The limiting device includes a guide frame, several fixed blocks and several elastic parts. Several of the fixed blocks are fixedly connected to the side wall of one side of the pressing rod. The guide frame is movably connected to the inner wall of the slide groove opened on the top of the shell through a slide rail. One end of several of the elastic parts is fixedly connected to the inner wall of the guide frame, and one end of several elastic parts away from the guide frame is fixedly connected to the limiting block, and both sides of the limiting block are inclined.

[0008] Preferably, the elastic member is a compression spring, one end of the compression spring is fixedly connected to the inner wall of the guide frame, and one end of the plurality of compression springs away from the guide frame is fixedly connected to one end of the limit block.

[0009] Preferably, one end of the pressing rod is fixedly connected to the pressing plate, and one end of the pressing rod away from the pressing plate is fixedly connected to the rubber sealing disk.

[0010] Preferably, the pressing plate is provided with anti-slip grooves.

[0011] Preferably, a sampling head is provided at the bottom of the shell, and scale lines are provided on the outer surface of the shell.

[0012] Preferably, the shell is made of polymethyl methacrylate.

[0013] Compared with related technologies, the wastewater sampling and detection sample collector provided by the utility model has the following beneficial effects:

[0014] Through the setting of the limiting device, when it is necessary to sample the wastewater through the collector, the pressing rod is first pulled through the pressing plate. At this time, the pressing rod will drive the fixed block set on itself to move. While the fixed block is moving, since the limiting block is set at an angle, it will squeeze the limiting block and the elastic part set on the outer shell, thereby moving the pressing rod. When the sampling is completed, the pressing rod is supported by the limiting block, and the fixed block is limited by the limiting block, thereby preventing the operator from accidentally pressing the pressing rod through the pressing plate. This device reduces the probability of inaccurate sampling, reduces the impact on the accuracy and reliability of the sampling data, and reduces the impact on the correct assessment of the wastewater quality.

[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a wastewater sampling and detection sample collector provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the cutaway structure shown; Figure 3 for Figure 2 The structural diagram of the limiting device shown; Figure 4 for Figure 3 Another perspective structural diagram of the limiting device is shown.

[0022] In the specific implementation process, Figures 1 to 4 The cam 6 is fixedly connected to the upper wall of the housing 1 and the lower wall of the housing 1 is fixedly connected to the upper wall of the housing 1. The cam 6 is fixedly connected to the upper wall of the housing 1 and the lower wall of the housing 1 is fixedly connected to the upper wall of the housing 1. The cam 6 is fixedly connected to the upper wall of the housing 1 and the lower wall of the housing 1 is fixedly connected to the upper wall of the housing 1. The water capacity, the shell 1 is made of polymethyl methacrylate material, which is also called acrylic or organic glass. It is a widely used polymer material with good weather resistance and good recyclability. When it is necessary to sample the wastewater through the collector, the pressing rod 2 is first pulled by the pressing plate 8. At this time, the pressing rod 2 will drive the fixed block 4 set on it to move. While the fixed block 4 moves, due to the inclined setting of the limit block 3, the limit block 3 and several compression springs 7 set on the shell 1 will be squeezed, so that the pressing rod 2 moves. When the sampling is completed, the pressing rod 2 is supported by the limit block 3. When the operator accidentally presses the pressing rod 2 through the pressing plate 8, the fixed block 4 will be limited by the limit block 3. The guide frame 6 and the limit block 3 can be moved through the slide groove 5 opened on the top of the shell 1, thereby preventing the operator from accidentally pulling the pressing rod 2 through the pressing plate 8.

[0023] The working principle provided by the present invention is as follows: during use, when it is necessary to sample wastewater through the collector, the pressing rod 2 is first pulled through the pressing plate 8. At this time, the pressing rod 2 will drive the fixed block 4 set on itself to move. While the fixed block 4 is moving, due to the inclined setting of the limit block 3, it will squeeze the limit block 3 and several compression springs 7 set on the outer shell 1, thereby moving the pressing rod 2. When the sampling is completed, the pressing rod 2 is supported by the limit block 3.
