Description

Technical Field

[0001] The utility model relates to the technical field related to water conservancy projects, in particular to a temporary water storage device used for water conservancy sampling. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water, such as rivers, lakes, seas, groundwater and various industrial drainage. When water sampling, water from different places must be sampled. Samples will be taken from many places and then tested. After the water is sampled, it must be temporarily stored and taken out for testing. However, there are some shortcomings in the current water storage devices. There will be impurities in the water. When the water is taken out of the current water storage device, the impurities will stick to the side walls of the water storage device, so the taken out water will affect the test results.

[0003] The patent document with publication number CN216847013U in the prior art provides a temporary water storage device for water sampling and testing; the device is provided with a stirring component, and the stirring component is provided to stir the water stored in the water storage, and the stirring component can stir the impurities deposited in the water storage body to make them float, and can also be output when the water is output, so as to ensure the accuracy of the water quality test results;

[0004] Although the device has many beneficial effects, the following problems still exist: when operating the stirring assembly of the device, the staff needs to adjust the knob to drive the baffle plate to rotate, thereby driving the stirring assembly at the upper end of the baffle plate to rotate, thereby achieving a stirring effect, but the up and down movement range of the baffle plate is limited, which leads to the number of rotations of the baffle plate and the stirring assembly being limited, which undoubtedly reduces the stirring effect of the device; for this reason, we propose a temporary water storage device for water conservancy sampling.

[0024] See also Figure 1-5 The utility model provides a technical solution: a temporary water storage device for water sampling, including a water storage body 1, a connecting pipe 11 is fixed at the lower end of the water storage body 1, a motor box 12 is fixed to the lower end surface of the water storage body 1, a positioning pin 14 is fixed to the lower end surface of the inner cavity of the water storage body 1, an outer magnetic rotor 13 is rotatably installed around the positioning pin 14, a stirring piece 17 is fixed to the outer periphery of the outer magnetic rotor 13, an inner magnetic rotor 15 matching the outer magnetic rotor 13 is fixed to the upper end surface of the motor box 12 through an output shaft, and the inner magnetic rotor 15 is rotatably installed in the positioning pin 14.

[0025] Working principle: When in use, connect the connecting pipe 11 to the external conduit, and cooperate with the external water pump to guide the external water into the water storage body 1, close the valve at the connecting pipe 11, and complete the sampling of the water sample. When the water sample needs to be stirred, start the motor inside the motor box 12, and drive the inner magnetic rotor 15 to rotate through its upper output shaft, and then through the magnetic connection effect between the inner magnetic rotor 15 and the outer magnetic rotor 13, the outer magnetic rotor 13 and the stirring plate 17 can be driven to rotate around the positioning pin 14. Through the rotating stirring plate 17, the effect of stirring the water sample is achieved, so that the impurities inside the water are suspended, ensuring that the impurities are evenly distributed in the water sample.

[0026] Specifically, a socket 16 is provided on the lower end surface of the locating pin 14, and the inner magnetic rotor 15 is rotatably installed in the socket 16. A locating ring 18 matching the upper end of the inner magnetic rotor 15 is inserted into the outer periphery of the locating pin 14, and a threaded ring 19 threadedly matched with the locating pin 14 is rotatably installed on the upper end surface of the locating ring 18. A limiting groove 141 is provided on the outer periphery of the locating pin 14, and a limiting slider 181 inserted into the limiting groove 141 is fixed on the inner end surface of the locating ring 18.

[0027] The insertion hole 16 is provided to facilitate the placement of the inner magnetic rotor 15 in the positioning pin 14, so that the positions of the inner magnetic rotor 15 and the outer magnetic rotor 13 match each other, ensuring that the rotating inner magnetic rotor 15 can drive the outer magnetic rotor 13 to rotate with it. Through the plug-in fit between the outer magnetic rotor 13 and the positioning pin 14, the outer magnetic rotor 13 and the stirring blade 17 can be installed and disassembled, which facilitates cleaning of the two.
