Description

Technical Field

[0001] This utility model relates to the field of wastewater sampling, and in particular to a wastewater sampling device for water pollution treatment. Background Technology

[0002] With the continuous increase in sewage discharge from industrial production, agricultural activities, and domestic sewage, water pollution has become a global environmental challenge. Pollutants such as heavy metals, organic matter, pathogens, and eutrophic substances not only disrupt the balance of aquatic ecosystems but also pose a direct threat to drinking water safety and human health. In actual monitoring, the composition of sewage varies significantly at different water levels. For example, surface sewage is easily affected by atmospheric deposition and floating pollutants, while deep sewage may accumulate precipitated heavy metals and recalcitrant organic matter. Therefore, collecting sewage samples from different water levels is crucial for a comprehensive understanding of water quality.

[0003] However, in the current use of sewage sampling devices, the sampling device is usually put into the water and the length of the release rope is adjusted to sample sewage at different water levels. In order to avoid cross-contamination, sewage at only one water level can be sampled in a single sampling process. As a result, the sampling device needs to be operated multiple times during the sampling process, which can easily affect the overall ease of operation of the sampling device. Utility Model Content

[0004] To overcome the problem that existing sewage sampling devices can only sample sewage from one water level at a time, which can easily affect the efficiency of the sampling device when sampling sewage from multiple water levels.

[0005] The technical solution of this utility model is as follows: a wastewater sampling device for water pollution treatment, comprising a first sampling tank, a second sampling tank disposed on the upper end of the first sampling tank, a third sampling tank disposed on the upper end of the second sampling tank, a connecting component respectively connected to the first sampling tank, the second sampling tank, and the third sampling tank, an adjusting component movably connected to the connecting component, a driving component connected to the adjusting component, a detection component respectively connected to the first sampling tank, the second sampling tank, and the third sampling tank, and a sealing component respectively connected to the inner wall of the first sampling tank, the second sampling tank, and the third sampling tank. The connecting component on the first sampling tank and the connecting component on the second sampling tank are connected by bolts, and the connecting component on the second sampling tank and the connecting component on the third sampling tank are connected by bolts.

[0006] The adjustment assembly includes a sealing cover movably connected to the connecting assembly, a positioning rod movably connected to the sealing cover, an anti-detachment plate connected to the positioning rod, a return spring connected to the sealing cover, several guide plates connected to the lower end of the sealing cover, and a support assembly movably connected to the guide plates.

[0007] The sealing assembly includes liquid inlet tanks respectively opened in the first sampling tank, the second sampling tank, and the third sampling tank; a pull rope assembly respectively connected to the inner wall of the first sampling tank, the second sampling tank, and the third sampling tank; a float assembly connected to the tensioning assembly; and a telescopic rope connected to the float assembly.

[0008] Preferably, the support assembly includes a positioning ring movably connected to the guide plate, a connecting plate connected to the inner wall of the positioning ring, a plurality of guide plates connected to the connecting plate, a liquid inlet groove formed on the connecting plate, and a liquid drain pipe connected to the lower end face of the connecting plate.

[0009] Preferably, the pull rope assembly includes a first connecting sleeve connected to the inner walls of the first sampling container, the second sampling container, and the third sampling container respectively; a first rotating ball movably connected to the first connecting sleeve; a tension rope connected to the first rotating ball; a second rotating ball connected to the tension rope; and a second connecting sleeve movably connected to the second rotating ball.

[0010] Preferably, the float assembly includes a mounting ring connected to the second connecting sleeve, a sealing ball connected to the mounting ring, and a tensioning rod connected to the sealing ball, wherein the mounting ring mates with the liquid inlet tank.

[0011] Preferably, the connecting assembly includes a second connecting strip connected to the first sampling tank, the second sampling tank, and the third sampling tank respectively, a first connecting strip connected to the second connecting strip, connecting holes respectively opened on the first connecting strip and the second connecting strip, a fixing bracket connected to the second connecting strip, and a fixing groove opened on the fixing bracket.

[0012] Preferably, the drive assembly includes a first motor connected to the positioning ring, a meshing wheel movably connected to the output shaft of the first motor, a meshing ring movably connected to the first sampling tank, the second sampling tank, and the third sampling tank respectively, a combination plate connected to the meshing ring, two rotating plates movably connected to the combination plate, a second motor connected to one of the rotating plates, a rotating bar movably connected to the rotating plate, a rotating bar movably connected to the rotating bar, and a clamping plate connected to the rotating bar. The meshing ring meshes with the meshing wheel, the two rotating plates mesh with each other, and the second motor is connected to the meshing ring.

[0013] Preferably, the detection assembly includes a first assembly block and a second assembly block connected to the first sampling tank, the second sampling tank, and the third sampling tank, a laser rangefinder connected to the second assembly block, and reflectors connected to the first sampling tank, the second sampling tank, and the third sampling tank, respectively.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model guides water into the first, second, or third sampling tank by setting a guide plate. At the same time, the physical properties of the return spring allow the sampling device to separate the sealing cover from the support assembly under the action of water pressure when it is put into the water, so that water can enter between the sealing cover and the support assembly. By setting return springs with different spring forces, wastewater at different water levels can be introduced into different sampling tanks to sample wastewater at different water levels, thereby greatly improving the working efficiency of the entire sampling device.

[0016] 2. This utility model uses a pull rope assembly to confine the float assembly within a fixed range when it enters the water body. The telescopic rope and pull rope assembly work together to allow the float assembly to move along the central axis of the liquid inlet tank. The float assembly also seals the liquid inlet tank, and the telescopic rope and tension rod seal the sampling container after sampling, thus enabling the sampling of sewage at different water levels.
