Description

Technical Field

[0001] This utility model relates to the technical field of water sampling devices, and in particular to a water sampling and collection device. Background Technology

[0002] A roof aquifer refers to a body of water located in the rock strata above an underground project. When this water connects to the project space through rock fissures, faults, or other channels, it can potentially cause a water inrush accident. By using geophysical exploration and drilling, the distribution range, thickness, water level, water pressure, and permeability coefficient of the roof aquifer can be determined. This allows for an assessment of the aquifer's potential to fill the project space with water. Real-time monitoring of aquifer water level and pressure changes provides early warning of dangerous signals such as abnormal increases in water pressure and sudden surges in water volume, offering a window of opportunity for project evacuation.

[0003] Water-bearing capacity describes the ability of an aquifer or rock mass to store and release groundwater, and is directly related to the development and utilization of groundwater, as well as the prevention and control of water hazards in engineering projects. During the exploration and dynamic monitoring of the water-bearing capacity of the roof aquifer, water samples need to be extracted from the aquifer using sampling devices for analysis.

[0004] Chinese patent application CN202411620943.4 discloses a water sampling device. This device utilizes a transmission assembly powered by the rotation of a movable toothed disc. This assembly synchronously drives multiple cleaning units to brush the collection points (the space between two collection holes on a pipe section for external liquid flow) on all pipe sections, effectively reducing the impact of accumulated impurities on the extracted liquid samples. However, this water sampling device only brushes the collection points to prevent accumulated impurities from clogging the collection holes; it lacks a tiered filtration system and cannot remove small particles of sediment or bacteria from the water, thus reducing the quality of the collected water samples. Utility Model Content

[0006] To achieve the above objectives, according to one aspect of the present invention, a water sampling and collection device is provided, including a water suction pipe and a blocking part, wherein the blocking part is disposed at the bottom end of the water suction pipe for intercepting and cleaning suspended matter at the bottom of the water suction pipe.

[0007] A sedimentation tube is fixedly installed at the top of the suction pipe and is used to settle particulate impurities in the sampled water.

[0008] A filter tube, which is fixedly installed at the top of the sedimentation tube, is used to filter particulate impurities in the sampled water.

Several horizontal cutting blades are fixedly provided at the top of the water-facing surface of the shovel body, with the blades perpendicular to the tangent of the arc-shaped surface of the shovel body and facing outward, for cutting the suspended objects horizontally. Several inclined vertical cutting blades are fixedly provided at the top of the shovel body, with adjacent vertical cutting blades overlapping vertically, for cutting the suspended objects vertically into small segments.

[0010] Furthermore, the blocking part includes an intercepting net, which is funnel-shaped, with the top of the intercepting net fixedly connected to the bottom of the water suction pipe, and the diameter of the top of the intercepting net being not less than the diameter of the bottom of the water suction pipe.

[0011] Furthermore, a retaining ring is fixedly provided on the outer ring of the top of the interception net.

[0012] Furthermore, a guide groove is provided on the outer side of the retaining ring, and the cross-section of the guide groove is T-shaped.

Detailed Implementation

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] This embodiment provides a water sampling and collection device, such as... Figure 1 As shown, it includes a water suction pipe 2 and a blocking part 1, which is located at the bottom end of the water suction pipe 2 and is used to intercept and clean up suspended matter at the bottom of the water suction pipe 2.

[0031] The suction pipe 2 uses a retractable corrugated pipe to adapt to different water depths.

[0032] The sedimentation tube 3 is fixedly installed at the top of the suction pipe 2 and is used to settle particulate impurities in the sampled water.

[0033] Filter tube 4 is fixedly installed at the top of the sedimentation tube 3 and is used to filter particulate impurities in the sampled water.

[0034] There are several cutting sections 8, all located at the blocking section 1. Each cutting section 8 includes a shovel body 81 with an arc-shaped water-facing surface for scooping up suspended objects outside the blocking section 1. Several horizontal cutting blades 82 are fixedly provided on the top of the water-facing surface of the shovel body 81. The blades of the horizontal cutting blades 82 are perpendicular to the tangent direction of the arc-shaped surface of the shovel body 81 and face outward, for cutting the suspended objects horizontally. Several inclined vertical cutting blades 83 are fixedly provided on the top of the shovel body 81. Adjacent vertical cutting blades 83 have overlapping parts in the vertical direction, for cutting the suspended objects vertically into small segments. The cutting section 8 is located in front of the bristles 18. The vertical cutting blade 83 is fixedly connected to the cleaning brush 15, and the blade faces outward. The shovel body 81 first shovels up the algae suspended on the surface of the interception net 11. The arc-shaped water-facing surface of the shovel body 81 facilitates the algae suspended along its surface to the vertical cutting blade 83. The bristles 18 then brush up the mud on the surface of the interception net 11 to prevent clogging. The brushed algae suspended is first cut into small segments by the horizontal cutting blade 82, and then cut into even smaller segments by the vertical cutting blade 83 to prevent it from entangled in the cleaning brush 15 and affecting its rotation.

[0035] like Figure 5 and 6 As shown, since the water-facing surface of the shovel body 81 is arc-shaped, when the cleaning brush 15 rotates, this arc-shaped surface will face the suspended algae. Therefore, the suspended algae that is scraped up will turn up along the arc-shaped surface. During the turning process, it will inevitably come into contact with the horizontal cutter 82 and the vertical cutter 83. The horizontal cutter 82 and the vertical cutter 83 are also in the process of continuous rotation. Therefore, the horizontal cutter 82 and the vertical cutter 83 in the rotating state will cut the suspended algae. The horizontal cutter 82 is located at the front end of the vertical cutter 83. The suspended algae first comes into contact with the horizontal cutter 82 and is cut by the horizontal cutter 82 before coming into contact with the vertical cutter 83 and being cut by it. Since the adjacent vertical cutters 83 have overlapping parts in the vertical direction, longer suspended algae can be cut into smaller segments.

[0036] like Figure 4 As shown, the blocking part 1 includes an interception net 11, which is funnel-shaped. The top of the interception net 11 is fixedly connected to the bottom of the water suction pipe 2, and the diameter of the top of the interception net 11 is not less than the diameter of the bottom of the water suction pipe 2.

[0037] A retaining ring 12 is fixedly provided on the outer ring of the top of the interception net 11.

[0038] A guide groove 13 is provided on the outer side of the retaining ring 12, and the cross-section of the guide groove 13 is T-shaped.

[0039] The bottom of the interception net 11 is equipped with a rotating shaft 14, and a number of cleaning brushes 15 are fixedly fixed in a radial pattern on the outer ring of the rotating shaft 14. A waterproof motor that drives the rotating shaft 14 to rotate is fixedly installed on the inner side of the interception net 11.

[0040] like Figure 5As shown, a slider 16 is fixedly provided at the other end of the cleaning brush 15. The slider 16 has a T-shaped cross-section, and several balls 17 are rolled on the top of the slider 16.

[0041] Both the slider 16 and the ball 17 are coated with lubricant to prevent jamming.

[0042] The bottom of the cleaning brush 15 is fixed with several bristles 18. The bristles 18 are in close contact with the surface of the interception net 11 to remove suspended matter such as algae attached to the surface of the interception net 11, preventing them from clogging the interception net 11 and affecting the extraction of sampled water; the slider 16 slides into the guide groove 13, and the ball bearing 17 converts the sliding friction between the slider 16 and the retaining ring 12 into rolling friction, thereby reducing the friction between the two and facilitating the movement of the cleaning brush 15.

[0043] like Figure 2 As shown, the sedimentation pipe 3 is spirally upward, and several isolation nets 6 are fixedly installed inside the sedimentation pipe 3. The spirally upward sedimentation pipe 3 reduces the flow velocity of the sampled water, which is conducive to the sedimentation of the sediment particles it contains. The sedimentation pipe 3 is equipped with isolation nets 6 at locations where the water flow velocity changes significantly, such as its inlet, highest point, lowest point, and outlet, which can effectively block sediment impurities. The mesh size of the isolation nets 6 decreases sequentially from the inlet to the outlet, filtering sediment impurities of different particle sizes.

[0044] A filter element 7 is fixedly installed inside the filter tube 4, such as Figure 3 As shown, the water-facing surface of the filter element 7 is provided with a groove 71, and the water-returning surface is fixedly provided with a protrusion 72. The groove 71 increases the contact area between the sampled water and the filter element 7, thereby improving the filtration effect; the protrusion 72 extends the flow path of the sampled water within the filter element 7, further improving the filtration effect.

[0045] Filter element 7 uses a conventional ceramic filter element with a pore size of 0.1 to 5 microns, which can filter out suspended particles (>0.1μm) such as bacteria (e.g., E. coli), rust, etc., as well as some colloids.

[0046] A water pump 5 is fixedly installed at the top of the filter tube 4. The inlet end of the water pump 5 is fixedly connected to the top of the filter tube 4, and the outlet end is connected to a hose to extract and collect the sampled water.

[0047] Place the bottom end of the suction pipe 2 into the water body to be sampled, start the waterproof motor, the motor drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the cleaning brush 15 to rotate, the rotating cleaning brush 15 drives the bristles 18 to rotate along the surface of the interception net 11, brushing off the algae and other suspended matter on its surface, preventing the suspended matter from clogging the interception net 11 and affecting the flow of water into the suction pipe 2.

[0048] Start water pump 5. Water pump 5 generates negative pressure in suction pipe 2, sedimentation pipe 3, and filter pipe 4, drawing the sampled water from interception net 11 into suction pipe 2. As the sampled water flows through suction pipe 2, it is blocked by the spiral upward wall of suction pipe 2, reducing the flow rate and causing large particles of silt and other impurities to settle. As the sampled water flows through isolation nets 6 in sequence, it is intercepted by isolation nets 6, filtering out larger particles of silt. The sampled water continues to flow upward and enters filter pipe 4, where it is filtered by filter element 7 to remove suspended particles such as bacteria and rust, as well as some colloids, improving the quality of the collected water sample.

[0049] When cleaning the collection device, high-pressure water is injected in reverse to flush it. The water pump 5 is removed, and a high-pressure water jet is injected from the top of the filter pipe 4. Because the filter element 7 has pores with a diameter of 0.1–5 micrometers, water molecules can pass through these pores, flushing away the impurities adsorbed inside the filter element 7. When the high-pressure water jet flows through the filter element 7 and the isolation screen 6, although its speed is reduced by the obstruction, it increases the water pressure on both sides of the filter element 7 and the isolation screen 6. Under the action of the pressure difference, the impurities attached to the filter element 7 and the isolation screen 6 are flushed away. Because isolation screens are installed at locations with significant changes in water flow velocity, such as the inlet, highest point, lowest point, and outlet of the sand settling pipe 3... The mesh size of the isolation net 6 decreases sequentially from the inlet to the outlet. Therefore, larger particles of impurities are filtered out at the inlet and the highest point of the sedimentation pipe 3. The smaller particles of impurities entering the lower part of the sedimentation pipe 3 are swept up by the clean water flow passing through the isolation net 6 in the opposite direction. The impurities are then carried away by the water flow in the opposite direction and discharged from the sedimentation pipe 3 after passing through the larger mesh of the isolation net 6. The sediment in the sedimentation pipe 3 and the impurities on the isolation net 6 are flushed out. Similarly, the impurities on the surface of the interception net 11 and in its mesh are also washed away, allowing for continued interception and filtration of the sampled water.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
