Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a novel water sampler for industrial wastewater pools. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to the wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and complex in composition. Industrial wastewater treatment refers to the water used in the industrial production process being properly treated and reused for production or properly discharged from the factory, including the management of production water and measures taken to facilitate the treatment of wastewater. An industrial wastewater sampler is required to sample the wastewater during industrial wastewater treatment.

[0003] The Chinese patent with authorization announcement number CN218524400U discloses a sampler for industrial wastewater treatment, including a sampling tube and a support plate. A rope is movably wound around the outer surface of the rope roller, and a sealing plate is movably inserted into the inner surface of the sampling tube. Three water intake cavities are opened in sequence on the inner surface of the sampling tube from top to bottom. The left sides of the three water intake cavities are fixedly connected to the water outlet, and the outer surface of the sealing plate is opened with three connecting ports.

[0004] In the above patent, when the sampling tube is placed underwater, wastewater of different depths is contaminated between the sealing plate and the filter screen. When it is moved to the depth where sampling is required, the sealing plate moves up, and when the wastewater enters the water intake chamber from the filter screen, it will be contaminated with wastewater of different depths, thereby affecting the accuracy of subsequent sampling and detection results. Therefore, this application provides a new type of water sampler for industrial wastewater pools to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a new type of water sampler for industrial wastewater pools to solve the problem proposed in the above background technology that when the sampling tube is placed underwater, wastewater of different depths is contaminated between the sealing plate and the filter screen. When it is moved to the depth required for sampling, the sealing plate moves up, and when the wastewater enters the water intake cavity from the filter screen, it will be contaminated with wastewater of different depths, thereby affecting the accuracy of subsequent sampling and detection results.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A novel water sampler for industrial wastewater pools comprises a sampling barrel and a telescopic rod fixedly mounted on the sampling barrel, a fixed rod fixedly mounted on the telescopic rod, and a fixed handle fixedly mounted on the fixed rod, two fixed seats fixedly mounted on the fixed rod, a rotating roller movably passing through the interior of the fixed seat, a wire rope wound around the rotating roller, three sampling cavities are provided inside the sampling barrel, a piston is provided on one side of the three sampling cavities, the piston is movably mounted inside the sampling barrel, a movable plate is slidably connected to the interior of the sampling barrel, one end of the wire rope is fixedly mounted on the top of the movable plate, and the movable plate is fixedly mounted on the top of the movable plate. Three movable grooves are provided on the movable plate, and two water grooves are provided on the movable plate. The two water grooves are arranged on the lower sides of the two upper movable grooves. Three water filter covers are fixedly installed on the sampling tube, and a water blocking platform that fits with the inner wall of the water filter cover is provided inside the water filter cover. A limiting sleeve is fixedly installed inside the water blocking platform, and a limiting rod is movably connected to one side of the limiting sleeve. One side of the limiting rod is fixedly connected to the inner wall of the movable groove, and a spring is fixedly provided on one side of the limiting rod, and the other end of the spring is fixedly connected to the inner wall of the limiting sleeve. A plurality of water holes are provided on the water filter cover.

[0008] Preferably, a rotating handle is fixedly mounted on the rotating roller.

[0009] Preferably, two limit bars are fixedly mounted on one side of the movable plate, and two limit slots for limiting the moving range of the limit bars are provided inside the sampling cylinder.

[0010] Preferably, the plurality of water holes are evenly distributed.

[0011] Preferably, the fixing handle is provided with anti-slip stripes.

[0012] Preferably, the three sampling cavities are evenly distributed inside the sampling cylinder.

[0013] Preferably, the three pistons are arranged at an angle.

[0014] Preferably, the limiting rod and the limiting sleeve are coaxially arranged.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting a water filter cover and a water blocking platform that can be extended to resist the water filter cover, when the sampling tube is extended downward into the wastewater, it can be ensured that the water filter cover is not water-permeable, thereby avoiding wastewater of different depths remaining in the water filter cover, which interferes with the results of the sampling test and ensures the accuracy of the test. By setting the water filter cover in a frustum shape with water holes evenly distributed on the surface, the water-permeable area and contact area are increased, thereby avoiding solid impurities clogging the water filter cover.

[0017] By setting the limit bar and the limit groove, when no force is applied to the rotating handle of the rotating roller, the movable plate moves downward due to gravity, and the limit bar is located at the lower end of the limit groove. When it is necessary to pass the water through the water trough to pass water through the water filter cover and the sampling chamber, the rotating roller is rotated, and the rope drives the movable plate to move upward. When the top of the limit bar hits the top of the limit groove, the water trough passes the sampling chamber and the water filter cover, the limit groove limits the movable range of the limit bar, and the limit bar guides the movement of the movable plate, so that the movable plate can smoothly realize vertical movement.

[0030] like Figure 1-5As shown, the embodiment of the utility model provides a new type of water sampling device for industrial wastewater pools, including a sampling barrel 1 and a telescopic rod 2 fixedly mounted on the sampling barrel 1, a fixed rod 3 fixedly mounted on the telescopic rod 2, and a fixed handle 4 fixedly mounted on the fixed rod 3. Two fixing seats 5 are fixedly mounted on the fixed rod 3. A rotating roller 6 is movably passed through the interior of the fixing seat 5. A wire rope 7 is wound around the rotating roller 6. Three sampling chambers 8 are opened inside the sampling barrel 1. The three sampling chambers 8 are evenly distributed inside the sampling barrel 1. A piston 9 is provided on one side of the three sampling chambers 8. The piston 9 is movably mounted inside the sampling barrel 1. A movable plate 10 is slidably connected to the interior of the sampling barrel 1. One end of the wire rope 7 is fixedly mounted on the top of the movable plate 10. Three movable grooves 11 are provided, and two water-passing grooves 12 are provided on the movable plate 10. The two water-passing grooves 12 are arranged on the lower sides of the two upper movable grooves 11. Three water filter covers 13 are fixedly installed on the sampling tube 1. The interior of the water filter cover 13 is provided with a water blocking platform 14 that fits with the inner wall of the water filter cover 13. A limiting sleeve 15 is fixedly installed inside the water blocking platform 14. One side of the limiting sleeve 15 is movably connected to a limiting rod 16. The limiting rod 16 and the limiting sleeve 15 are coaxially arranged. One side of the limiting rod 16 is fixedly connected to the inner wall of the movable groove 11. A spring 17 is fixedly installed on one side of the limiting rod 16. The other end of the spring 17 is fixedly connected to the inner wall of the limiting sleeve 15. A plurality of water holes are provided on the water filter cover 13, and the plurality of water holes are evenly distributed. A rotating handle is fixedly installed on the roller 6. In the initial state, the water blocking platform 14 is inside the water filter cover 13, blocking the water hole of the water filter cover 13, and inserting the piston 9 into the sampling tube 1 so that the sampling chamber 8 is in a closed state. The staff holds the fixed handle 4 and adjusts the telescopic rod 2 to extend the sampling tube 1 into the water. The rope 7 extends as the movable plate 10 moves downward. When the sampling tube 1 moves to the position where sampling is required, the staff rotates the rotating handle to drive the rotating roller 6 to rotate, thereby driving the movable plate 10 to move upward during the winding of the rope 7, and the movable plate 10 drives the water blocking platform 14 to move upward. The water filter cover 13 and the water blocking platform 14 contact the pressure exerted on the water blocking platform 14. The pressure is decomposed into vertical downward force and horizontal force toward one side of the movable groove 11, thereby pushing the water blocking. The platform 14 and the limiting sleeve 15 move toward the inside of the movable groove 11, and the limiting sleeve 15 slides on the outer wall of the limiting rod 16 while squeezing the spring 17. The water blocking platform 14 moves to the inside of the movable groove 11, and the movable plate 10 drives the water trough 12 to move to the side of the water filter cover 13. After the water flows from the water hole of the water filter cover 13 to the water trough 12, it enters the interior of the sampling chamber 8. After the collection is completed, the staff releases the rotating handle on one side of the rotating roller 6, and the movable plate 10 moves downward due to gravity. When the water blocking platform 14 moves to the side of the water filter cover 13, the spring 17 stretches to drive the limiting sleeve 15 to move on the limiting rod 16, so that the limiting sleeve 15 drives the water blocking platform 14 to contact the inner wall of the water filter cover 13, and then adjusts the telescopic rod 2 to drive the sampling tube 1 to move upward.By providing the water filter cover 13 and the water blocking platform 14 that can extend and retract to contact the water filter cover 13, the water filter cover 13 can be kept clear of water when the sampling tube 1 is extended downward into the wastewater. This prevents wastewater from remaining at varying depths in the water filter cover 13 and interfering with the sampling test results, thus ensuring test accuracy. By configuring the water filter cover 13 in a frustum shape with water holes evenly distributed on its surface, the water flow area and contact surface are increased, thereby preventing solid impurities from clogging the water filter cover 13.

[0031] like Figure 3 As shown, two limit bars 18 are fixedly installed on one side of the movable plate 10, and two limit grooves 19 are provided inside the sampling tube 1 for limiting the moving range of the limit bars 18. By setting the limit bars 18 and the limit grooves 19, when no force is applied to the rotating handle of the rotating roller 6, the movable plate 10 moves downward due to gravity, and the limit bars 18 are located at the lower end of the limit grooves 19. When the water trough 12 needs to pass through the water filter cover 13 and the sampling chamber 8 for water, the rotating roller 6 is rotated, and the rope 7 drives the movable plate 10 to move upward. When the top of the limit bar 18 hits the top of the limit groove 19, the water trough 12 passes through the sampling chamber 8 and the water filter cover 13. The limit groove 19 limits the moving range of the limit bar 18, and the limit bar 18 guides the movement of the movable plate 10, so that the movable plate 10 can smoothly achieve vertical movement.

[0032] like Figure 1 and Figure 2 As shown, anti-slip stripes are provided on the fixed handle 4. By providing the anti-slip stripes, when the staff holds the fixed handle 4, the friction between the hand and the outer wall of the fixed handle 4 is increased, which has an anti-slip effect, allowing the staff to hold the fixed handle 4 and the entire device more firmly.

[0033] like Figure 4 As shown, the three pistons 9 are arranged at an angle. After the sampling is completed, the pistons 9 are pulled out and the sewage flows out along the inclined angle.

[0034] The technical solution provided by the present invention is that in the initial state, the water blocking platform 14 is inside the water filter cover 13, blocking the water through hole of the water filter cover 13, and inserting the piston 9 into the sampling tube 1 so that the sampling chamber 8 is in a closed state. The staff holds the fixed handle 4 and adjusts the telescopic rod 2 to make the sampling tube 1 extend into the water, and the rope 7 extends as the movable plate 10 moves downward. When the sampling tube 1 moves to the position where sampling is required, the staff rotates the rotating handle to drive the rotating roller 6 to rotate, thereby driving the movable plate 10 to move upward during the winding of the rope 7, and the movable plate 10 drives the water blocking platform 14 to move upward. The contact surface of the water filter cover 13 and the water blocking platform 14 exerts pressure on the water blocking platform 14, and the pressure is decomposed into vertical downward force and horizontal force toward one side of the movable groove 11, thereby pushing the water blocking platform 14 and the limiting sleeve 15 to move toward the inside of the movable groove 11, and the limiting sleeve 15 is on the limiting rod 16 When the outer wall of the sleeve is slid, the spring 17 is squeezed, and the water blocking platform 14 moves to the inside of the movable groove 11, and the movable plate 10 drives the water trough 12 to move to the side of the water filter cover 13. At this time, the top of the limit bar 18 hits the top of the limit groove 19, and the water trough 12 connects the sampling chamber 8 and the water filter cover 13. After the water flows from the water hole of the water filter cover 13 to the water trough 12, it enters the interior of the sampling chamber 8. After the collection is completed, the staff releases the rotating handle on one side of the rotating roller 6, and the movable plate 10 moves downward due to gravity. When the water blocking platform 14 moves to one side of the water filter cover 13, the spring 17 extends and drives the limiting sleeve 15 to move on the limiting rod 16, so that the limiting sleeve 15 drives the water blocking platform 14 to hit the inner wall of the water filter cover 13, and then adjusts the telescopic rod 2 to drive the sampling tube 1 to move up. After the sampling is completed, the piston 9 is pulled out, and the sewage flows out along the inclined angle.

[0035] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
