Description

Technical Field

[0001] The utility model relates to the technical field of wastewater sampling, in particular to an adjustable groundwater wastewater sampling device. Background Art

[0002] Groundwater is formed by atmospheric precipitation and surface runoff. Groundwater can also cause some hazards. For example, excessive groundwater can cause railway and highway collapse, flood mining tunnels, and form swamps. At the same time, the water quality and quantity of groundwater are affected by precipitation and runoff, and are greatly affected by the soil environment and soil sanitation. It is an important basis for studying pollution sources. Therefore, regular testing of groundwater can indirectly show the soil environment and soil sanitation.

[0003] A Chinese patent with announcement number CN215004435U discloses a groundwater sampler with adjustable depth for hydrological exploration. It uses a cable to directly drop the sampler to a specified depth of groundwater for sampling. The sampler is equipped with a water level survey device that can be effectively dropped to the specified water level, and can accurately sample water levels at different depths.

[0004] The above solution uses a cable to control the depth of the sampler in the groundwater to complete sampling at different depths. However, the sampler can only complete one sampling at a time. When sampling at different groundwater depths, the sampler needs to be lifted and lowered multiple times, which is cumbersome and inefficient. To address this problem, we provide an adjustable groundwater and wastewater sampling device. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-3 As shown, the utility model provides a technical solution: an adjustable groundwater wastewater sampling device, including a fixing frame 1, multiple sampling tanks 5, multiple mounting components, a support seat 11, a support component and an adjustment component.

[0028] A lifting ring 2 is installed on the fixing frame 1. The fixing frame 1 is L-shaped. The lifting ring 2 is located at the top of the fixing frame 1. The wire rope installed on the winch can be installed on the lifting ring 2, so that the winch can be used to lift or lower the fixing frame 1 to adjust the sampling depth.

[0029] A plurality of sampling tanks 5 are equidistantly arranged on one side of the fixed frame 1. A water inlet 6 is provided on the sampling tank 5. Wastewater can be collected inside the sampling tank 5 through the water inlet 6. An adjusting block 7 is provided on the sampling tank 5. A closing groove 8 is provided on the adjusting block 7. The adjusting block 7 is slidably connected to the sampling tank 5 through the closing groove 8. When the adjusting block 7 covers the water inlet 6 on the sampling tank 5, the water inlet 6 is closed. After the adjusting block 7 is removed, the wastewater can enter the sampling tank 5 from the water inlet 6.

[0030] The plurality of mounting components include a first fixing plate 3 fixedly connected to the fixing frame 1 and a second fixing plate 4 fixedly connected to the fixing frame 1 , and the sampling tank 5 is located between the first fixing plate 3 and the second fixing plate 4 .

[0031] The support base 11 is arranged between the first fixed plate 3 and the second fixed plate 4. A placement groove 12 is provided on the support base 11, and the bottom end of the sampling tank 5 is inserted into the placement groove 12. The support base 11 can be installed on the sampling tank 5 through the placement groove 12, thereby completing the positioning of the sampling tank 5. After the sampling of the sampling tank 5 is completed, the sampling tank 5 can be removed from the support base 11.

[0032] The support assembly is arranged between the support seat 11 and the second fixed plate 4, and is used to push the support seat 11 to move so that the sampling tank 5 is fixed between the first fixed plate 3 and the support seat 11. The support assembly includes a support frame 16, the bottom end of the support frame 16 is fixedly connected to the second fixed plate 4, and a support bolt 17 is threadedly connected to the support frame 16, and the top end of the support bolt 17 is against the support seat 11.

[0033] The height of the support bolt 17 at the upper part of the support frame 16 is adjusted by rotating the support bolt 17, so that the support bolt 17 pushes the support seat 11 to move upward and the top of the sampling tank 5 is abutted against the first fixing plate 3, thereby completing the fixation of the sampling tank 5.

[0034] The support assembly also includes a storage tube 13 fixedly connected to the second fixed plate 4, a slider 14 is slidably connected in the storage tube 13, a support column 15 is fixedly connected to the slider 14, and the top of the support column 15 passes through the storage tube 13 and is fixedly connected to the support seat 11. When the support seat 11 moves, it can drive the slider 14 on the support column 15 to slide in the storage tube 13, which can guide the movement of the support seat 11, avoid the support seat 11 from tilting during the movement, and improve the stability of the sampling tank 5 in the support seat 11.

[0035] The adjustment component is arranged on the fixed frame 1 and is used to adjust the position of the adjustment block 7 on the sampling tank 5. The adjustment component includes a guide groove 9 opened on the fixed frame 1. One end of the adjustment block 7 passes through the guide groove 9 and extends to the outside of the guide groove 9, and the adjustment block 7 is slidably connected to the guide groove 9.

[0036] The adjustment assembly also includes an electric push rod 10 installed on the fixed frame 1. The electric push rod 10 needs to use waterproof material. The telescopic end of the electric push rod 10 is fixedly connected to the adjustment block 7. When sampling is required, the telescopic end of the electric push rod 10 can drive the adjustment block 7 to move in the guide groove 9, thereby moving the adjustment block 7 on the sampling tank 5 and exposing the water inlet 6 to the outside, so that the wastewater is collected into the sampling tank 5 through the water inlet 6. Since there are multiple sampling tanks 5, at a certain depth, only one sampling tank 5 is sampling, and the other sampling tanks 5 are in a closed state.
