Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, specifically a portable water quality testing and sampling device for water conservancy projects. Background Technology

[0002] Water quality testing is the process of analyzing and measuring the physical, chemical, and biological properties of water bodies. Using specialized methods and equipment, it detects the content and properties of various substances in the water, covering indicators such as pH, hardness, heavy metal concentration, and microbial count. Its purpose is to assess whether the water quality meets relevant standards, such as drinking water hygiene standards and industrial water requirements. This is of great significance for protecting human health, maintaining ecological balance, and ensuring the normal operation of industrial production. Whether for domestic water use, agricultural irrigation water, or industrial wastewater treatment, water quality testing is a crucial step, providing a scientific basis for the rational utilization and protection of water resources.

[0003] Before conducting water quality testing, water samples need to be taken. However, during the sampling process, using conventional sampling tubes can easily allow impurities such as tree branches, sand, and duckweed to enter the sampling tube, interfering with the water quality testing process and causing changes in the test results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a portable water quality testing and sampling device for water conservancy projects, including a main body, a material taking mechanism slidably connected to the top of the main body, a fixing mechanism fixedly connected to the surface of the main body, the material taking mechanism being located above the main body, and the fixing mechanism being located below the material taking mechanism;

[0005] The main body includes a sampling cylinder with a filter groove on its surface. A feed pipe is threaded to the bottom of the sampling cylinder. A limiting plate is fixedly connected to the inner wall of the feed pipe. A limiting groove is formed at the top of the limiting plate. A filter plate is snapped into the limiting groove. An installation sleeve is fixedly connected to the surface of the sampling cylinder. A pressure hole and a positioning hole are formed on the surface of the installation sleeve.

[0006] Through the above technical solution, by setting up a filter tank and a filter plate, when sampling water quality, the water source comes into contact with the surface of the sampling tube and passes through the filter tank into the sampling tube, filtering out large particles of branches, sand, and other impurities on the surface of the water source. This avoids large particles of impurities interfering with the test results during the testing process. When the water source inside the sampling tube is taken out, the water source passes through the filter plate to undergo secondary filtration of algae, duckweed, and other substances on the surface, avoiding interference with the test results.

[0007] As a further improvement to the above solution, the number of filter tanks is set to several, and the several filter tanks are evenly distributed on the surface with respect to the top center of the main body.

[0008] With the above technical solution, multiple filter tanks are symmetrically and evenly distributed around the top center of the main structure. This arrangement can make the filtration in all directions more uniform when the water sample enters the sampling tube, avoiding excessive or insufficient local filtration pressure, thereby improving the overall filtration effect and ensuring that as many large impurities as possible are removed when the water sample enters the sampling tube.

[0009] As a further improvement to the above scheme, the bottom of the sampling tube is in contact with the top of the filter plate.

[0010] The above technical solution enables the filter plate to be stably fixed inside the limiting groove, preventing it from shaking.

[0011] As a further improvement to the above solution, the material handling mechanism includes a piston, a hollow tube fixedly connected to the top of the piston, a pressing plate fixedly connected to the top of the hollow tube, a slider fixedly connected to the bottom of the pressing plate, and a slide rail slidably connected to the surface of the slider.

[0012] Through the above technical solution, the piston in the sampling mechanism contacts the inner wall of the sampling cylinder, effectively pushing the water sample. The hollow tube connects the piston and the pressing plate, allowing the pressing force of the pressing plate to be effectively transmitted to the piston. The pressing plate is easy for the user to operate, and the cooperation of the slider and slide rail makes the pressing plate more stable during up and down movement, ensuring a smooth sampling process.

[0013] As a further improvement to the above solution, the piston is in contact with the inner wall of the sampling cylinder, and there are two sliders. The two sliders are evenly distributed on the surface symmetrically with respect to the bottom center of the pressing plate, and the bottom of the slide rail is fixedly connected to the top of the mounting sleeve.

[0014] Through the above technical solution, the contact between the piston and the inner wall of the sampling cylinder ensures that the water sample will not leak and can be effectively extracted during the sampling process. The two sliders are symmetrically and evenly distributed on the surface with respect to the bottom center of the pressing plate. Combined with the setting that the bottom of the slide rail is fixed to the top of the mounting sleeve, the force on the pressing plate is more even when it moves up and down, and it is not easy to tilt, thereby improving the accuracy and stability of the sampling operation.

[0015] As a further improvement to the above solution, the fixing mechanism includes a fixing platform, a positioning plate fixedly connected to the inner wall of the fixing platform, a threaded rod threadedly connected to the inner wall of the fixing platform, a fixing plate fixedly connected to the left end of the threaded rod, and a handle fixedly connected to the right end of the threaded rod.

[0016] Through the above technical solution, the fixing platform in the fixing mechanism provides support for other components. The positioning plate is fitted into the positioning hole, which helps to accurately install and position the fixing platform and the main body. The threaded rod is threadedly connected to the fixing platform for easy adjustment. The fixing plate and handle are located at both ends of the threaded rod, respectively. The fixing plate is used to cooperate with the pressure hole of the main body to achieve the fixing function, and the handle allows the user to rotate the threaded rod to achieve fixing and disassembly operations.

[0017] As a further improvement to the above solution, the positioning plate is sleeved inside the positioning hole, and the fixing plate is concentric with the pressure hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention, by setting up a filter tank and a filter plate, allows the water source to contact the surface of the sampling tube during water sampling. The water then passes through the filter tank into the sampling tube, filtering out large particles such as branches and sand from the surface of the water source. This prevents large particles from interfering with the test results during the testing process. When the water source inside the sampling tube is removed, it undergoes a secondary filtration process through the filter plate to remove algae, duckweed, and other substances from the surface, preventing them from interfering with the test results.

[0020] This utility model features a feeding tube that can be screwed out from the bottom thread of the sampling cylinder. The filter plate can be removed by inverting the feeding tube, making it easy to replace and clean the filter plate. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of a portable water quality testing and sampling device for water conservancy projects includes a main body 1, a material taking mechanism 2 slidably connected to the top of the main body 1, and a fixing mechanism 3 fixedly connected to the surface of the main body 1. The material taking mechanism 2 is located above the main body 1, and the fixing mechanism 3 is located below the material taking mechanism 2.

[0030] The main body 1 includes a sampling cylinder 101, a filter groove 102 on the surface of the sampling cylinder 101, a feed pipe 103 threadedly connected to the bottom of the sampling cylinder 101, a limit plate 104 fixedly connected to the inner wall of the feed pipe 103, a limit groove 105 on the top of the limit plate 104, a filter plate 106 snapped into the limit groove 105, an installation sleeve 107 fixedly connected to the surface of the sampling cylinder 101, a pressure hole 108 on the surface of the installation sleeve 107, and a positioning hole 109 on the surface of the installation sleeve 107.

[0031] The number of filter tanks 102 is set to several, and the filter tanks 102 are evenly distributed on the surface with the top center of the main body 1 symmetrically.

[0032] The bottom of the sampling cylinder 101 is in contact with the top of the filter plate 106.

[0033] The material handling mechanism 2 includes a piston 201, a hollow tube 202 fixedly connected to the top of the piston 201, a pressing plate 203 fixedly connected to the top of the hollow tube 202, a slider 204 fixedly connected to the bottom of the pressing plate 203, and a slide rail 205 slidably connected to the surface of the slider 204.

[0034] The piston 201 contacts the inner wall of the sampling cylinder 101. There are two sliders 204. The two sliders 204 are evenly distributed on the surface symmetrically with respect to the bottom center of the pressing plate 203. The bottom of the slide rail 205 is fixedly connected to the top of the mounting sleeve 107.

[0035] The fixing mechanism 3 includes a fixing platform 301, a positioning plate 302 fixedly connected to the inner wall of the fixing platform 301, a threaded rod 303 threadedly connected to the inner wall of the fixing platform 301, a fixing plate 304 fixedly connected to the left end of the threaded rod 303, and a handle 305 fixedly connected to the right end of the threaded rod 303.

[0036] The positioning plate 302 is sleeved inside the positioning hole 109, and the fixing plate 304 is concentric with the pressure hole 108.

[0037] The implementation principle of a portable water quality testing and sampling device for water conservancy projects in this application embodiment is as follows: when water quality testing and sampling is carried out, the sampling tube 101 is taken from the inside of the fixed platform 301 and placed inside the water source to be sampled. The water source enters the inside of the sampling tube 101 through the filter tank 102. After sampling is completed, the positioning plate 302 is sleeved inside the positioning hole 109, and the threaded rod 303 is rotated. The threaded rod 303 drives the fixed plate 304 to move into the pressure hole 108 until the fixed plate 304 contacts the pressure hole 108 and fixes it.

[0038] Place the beaker on the top of the inner wall of the fixed platform 301 and press the pressing plate 203. The pressing plate 203 drives the piston 201 to slide inside the sampling cylinder 101, which compresses the air inside. The water source that needs to be tested inside the sampling cylinder 101 is filtered through the filter plate 106 after being compressed by the air and then drips through the discharge pipe 103.

[0039] When the filter plate 106 needs to be replaced, unscrew the feed pipe 103 from the bottom thread of the sampling cylinder 101, and turn the feed pipe 103 upside down to remove the filter plate 106, which facilitates the replacement and cleaning of the filter plate 106.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
