Description

Technical Field

[0001] This utility model relates to the field of automatic water quality samplers, and in particular to a sampling bucket for an automatic water quality sampler with equal scale. Background Technology

[0002] Sampling is an indispensable part of water quality monitoring. Accurate sampling not only provides a reliable basis for water quality analysis, but also provides strong data support for environmental protection and governance. The proportional water sampler is a sample analysis instrument based on the principle of flow ratio control, used to automatically collect water samples and mix them to form a representative water sample.

[0003] In actual use, the water sample collected by the proportional water quality automatic sampler is automatically dispensed into a predetermined volumetric container. However, it is inconvenient to disassemble and repair the sampling container and the predetermined volumetric container, and the collected water sample cannot be premixed in time in the sampling container, which affects the accuracy of subsequent water sample analysis. This paper proposes a sampling container for the proportional water quality automatic sampler to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in existing technologies, this utility model proposes a sampling bucket for an automatic water quality sampler with equal proportions. This solves the technical problem in the background technology where, during actual use, the collected water samples are automatically dispensed into predetermined volumetric bottles, but the sampling bucket and predetermined volumetric bottles are inconvenient to disassemble and repair, and the collected water samples are not premixed in time within the sampling bucket, affecting the accuracy of subsequent water sample analysis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampling bucket of an automatic water quality sampler with equal proportions includes the automatic water quality sampler, which contains a sampling bucket and a pre-quantitative bucket. The sampling bucket and the pre-quantitative bucket are connected by the same liquid guiding pipe. A first material loading frame is slidably connected to the bottom of the automatic water quality sampler, and the sampling bucket is inserted into the first material loading frame. Second material loading frames are slidably inserted into the inner walls of the left and right sides of the automatic water quality sampler, and the pre-quantitative bucket is inserted into the second material loading frames. A mixing mechanism is vertically inserted through the top surface of the sampling bucket.

[0007] Preferably, three U-shaped limiting seats are fixedly installed on the bottom of the automatic water sampler, and the openings of the three U-shaped limiting seats are all vertically upward. Several pulleys are fixedly installed at the lower end of the first material frame, and the pulleys are respectively arranged close to the front and rear sides of the first material frame. On the same side, the pulleys are respectively inserted into the openings of the three U-shaped limiting seats.

[0008] Preferably, horizontal limiting seats are fixedly installed on the inner walls of both the left and right sides of the automatic water sampler, and limiting slots are provided on the opposite side walls of the two horizontal limiting seats. Strip-shaped inserts are fixedly connected to the left and right side walls near the lower end of the second material frame, and the two strip-shaped inserts are respectively inserted into the two limiting slots.

[0009] Preferably, the U-shaped limiting seat, the horizontal limiting seat, and the strip-shaped insert are all wear-resistant alloy products, and the cross-section of the horizontal limiting seat is arranged in an equilateral trapezoid.

[0010] Preferably, the mixing mechanism includes L-shaped seats fixedly installed on the top surfaces of the left and right sides of the sampling barrel. A drive motor is fixedly installed at the upper end of the horizontal section of the left L-shaped seat. A spiral stirring rod is vertically rotatably installed through the top surface of the sampling barrel near the left and right sides. The upper ends of the two spiral stirring rods are respectively vertically rotatably installed through the horizontal sections of the two L-shaped seats. The upper end of the left spiral stirring rod is fixedly connected to the drive shaft of the drive motor. A transmission wheel is coaxially fixedly connected to one end of the two spiral stirring rods located in the L-shaped seat. The two transmission wheels are connected by belt drive.

[0011] Preferably, the liquid guiding pipeline is connected to a liquid guiding cover at its lower end inside the sampling bucket, and a filter screen is fixedly installed on the annular inner wall of the liquid guiding cover near its lower end.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By inserting the sampling bucket and the pre-quantitative bucket into the first and second material loading frames respectively, inserting the pulley at the lower end of the first material loading frame into the opening of the U-shaped limiting seat, and inserting the strip block on the second material loading frame into the limiting slot on the horizontal limiting seat, it is convenient to quickly position and replace the sampling bucket and the pre-quantitative bucket for maintenance.

[0014] 2. The drive motor drives the spiral stirring rod on the left L-shaped seat to rotate, which in turn drives the right spiral stirring rod to rotate through the two transmission wheels connected by the belt drive. This causes the two spiral stirring rods to continuously stir the collected water sample in the premixed sampling tank, ensuring the accuracy of subsequent water sample analysis.
