Description

Technical Field

[0001] This utility model relates to the field of automatic water quality samplers, and in particular to an anti-clogging sampler for automatic water quality samplers. Background Technology

[0002] Automatic water samplers are instruments used to automatically collect, store, and transmit water samples. They utilize automation technology to achieve accurate collection and long-term preservation of water samples, ensuring the accuracy and reliability of water quality data. They are suitable for routine monitoring of surface water, sewage pipe networks, and sewage treatment plants, as well as for precise sampling in special scenarios such as industrial drainage outlets.

[0003] Most automatic water samplers are fixed samplers, which lack anti-clogging structures at the liquid inlet of the sampling port. This makes it easy for impurities in the water to clog the sampling port, and it is also inconvenient to quickly introduce the collected water sample into the automatic sampler. This paper proposes an anti-clogging sampler for automatic water samplers to solve the above problems. Utility Model Content

[0004] To address the shortcomings and defects in existing technologies, this utility model proposes an anti-clogging sampler for automatic water quality samplers. This solves the technical problem that most automatic water quality samplers in the background technology are fixed samplers, which lack an anti-clogging structure at the liquid inlet of the sampling port, making it easy for impurities in the water area to clog the sampling port and making it inconvenient to quickly introduce the collected water sample into the automatic sampler.

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

[0006] An anti-clogging sampler for an automatic water quality sampler includes a sampling cylinder. A U-shaped bracket is fixedly installed at the upper end of the sampling cylinder at its center. A spiral stirring rod is vertically rotatably inserted through the U-shaped bracket. The lower end of the spiral stirring rod vertically rotatably penetrates the top surface of the sampling cylinder and extends into its interior. A drainage component is connected to the upper end of the spiral stirring rod. An anti-clogging material component is provided at the lower end of the sampling cylinder. An annular sealing cover is fitted onto the lower end of the sampling cylinder. Several fixing bolts are fixedly connected between the vertical section sidewall of the annular sealing cover and the sampling cylinder.

[0007] Preferably, the sampling tube has an inverted T-shaped cross-section, a bearing seat is fixedly installed at the upper end of the horizontal section of the U-shaped bracket, the spiral stirring rod rotates vertically through the bearing seat, and the rod section of the spiral stirring rod is hollow.

[0008] Preferably, an L-shaped base is fixedly installed on the upper rear side of the sampling tube, a drive motor is fixedly installed on the upper end of the L-shaped base, a connecting rod is fixedly connected to the lower end of the drive shaft of the drive motor, the connecting rod is vertically rotatable through the horizontal section of the L-shaped base, a drive wheel is coaxially fixedly connected to the connecting rod, and the drive wheel and the driven wheel are connected by belt drive.

[0009] Preferably, the drainage assembly includes a rotary joint fixedly installed on the upper end of the U-shaped bracket, the hollow rod section of the spiral stirring rod is connected to the rotary joint, the upper end of the rotary joint is connected to a drainage pipe, and one end of the spiral stirring rod located inside the U-shaped bracket is coaxially and fixedly connected to a driven wheel.

[0010] Preferably, the anti-clogging material assembly includes an annular connecting block fixedly connected to the annular sidewall near the lower end of the spiral stirring rod. Two L-shaped stirring blocks are fixedly connected to the annular sidewall of the annular connecting block. A liquid suction cover is connected to the lower end of the hollow rod of the spiral stirring rod. Several conical crushing teeth are fixedly connected to the opposite sidewalls of the vertical sections of the two L-shaped stirring blocks.

[0011] Preferably, a plurality of the fixing bolts are arranged at equal intervals around the annular sealing cover, and a filter screen is fixedly installed at the upper end of the horizontal section of the annular sealing cover, with the filter screen facing the liquid suction cover.

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

[0013] By fixing the annular sealing cover to the lower end of the sampling tube, the filter screen performs preliminary filtration of the water sample at the sampling port. The drive motor drives the annular connecting block to rotate, which in turn drives several conical crushing teeth to rotate in conjunction with the L-shaped stirring block. This continuously breaks up the collected water sample introduced into the suction hood, further preventing impurities from clogging the suction hood and preventing water impurities from clogging the sampling port.

Several conical crushing teeth 17 are fixedly connected to the opposite sidewalls of the vertical sections of the two L-shaped stirring blocks 15. The spiral stirring rod 3 drives the annular connecting block 14 to rotate, so that the annular connecting block 14 cooperates with the L-shaped stirring blocks 15. 5 drives several conical crushing teeth 17 to rotate, continuously crushing the collected water sample introduced into the liquid suction hood 16, further preventing impurities from clogging the liquid suction hood 16 and preventing water impurities from clogging the sampling tube 1.
