Description

Technical Field

[0001] This utility model relates to the field of flue gas desulfurization technology, specifically to a sampling device for extracting seawater from ditches. Background Technology

[0002] During the operation of a seawater desulfurization system, it is necessary to continuously monitor parameters such as the pH value of the seawater in the seawater channel. Sampling requires a small volume of seawater and a low pumping head (generally 3-5 meters), but real-time and continuous sampling is essential. To meet these requirements, an electric water pump is typically used to continuously extract seawater from the channel to ensure the real-time and accurate readings. This application provides a self-powered seawater sampling device that does not consume electrical energy.

[0003] Chinese patent CN216717906U discloses a sampling device for marine engineering inspection. It includes a bottom assembly, a sealed shell fixedly mounted on the top surface of the bottom assembly, and a sampling component mounted on the inner wall of the bottom assembly. The sampling component includes an outer cylinder, a set of drive push rods, and a water pump. The peripheral surfaces of the drive push rods and the bottom surface of the water pump are fixedly connected to the bottom assembly. A rotating cylinder is rotatably connected to the inner wall of the outer cylinder. A servo motor is fixedly mounted on the peripheral surface of the outer cylinder, and one end of the servo motor's output shaft is drively connected to the rotating cylinder. A stamped shaft tube is fixedly mounted at the axial position of the rotating cylinder. This invention, through the design of the bottom assembly and the sampling component, enables the device to efficiently complete the sampling of seabed sediment during marine engineering inspection. Furthermore, during sampling operations, the device can quickly seal the bottom of the sampling drill tube by controlling the expansion of the sealing ring.

Detailed Implementation

[0023] like Figure 1As shown, the sampling device for extracting seawater from a ditch according to this utility model includes: a fixed column 2, a sleeve 4, a drive bearing 6, a drive gear 7, a driven bearing 8, an impeller 9, a locking nut 10, a detector 23, a guide vane 13, a pump impeller 14, a drive shaft 17, a driven shaft 18, a pump casing 21, and a driven gear 22. The fixed column 2 is fixed to the ditch bed 1 by a fixing plate 5. The pump casing 21 is composed of an upper horizontal pipe 12, a longitudinal pipe 16, and a lower horizontal pipe 15 connected in sequence. The upper horizontal pipe 12 and the lower horizontal pipe 15 are respectively connected in parallel to the upper and lower ends of the vertical longitudinal pipe 16. The upper horizontal pipe 12 is located above the water level, and most of the longitudinal pipe 16 and the lower horizontal pipe 15 are located below the water level.

[0024] The lower horizontal tube 15 has a flared end 3. One end of the driven shaft 18 is located near the opening of the lower horizontal tube 15 and is equipped with two sets of guide vanes 13 and a pump impeller 14 connected in series. The other end passes through the longitudinal tube 16 and is mounted on the longitudinal tube 16 via the driven bearing 8. The driven gear 22 is fixed on the other end of the driven shaft 18. The drive shaft 17 is mounted on the longitudinal tube 16 above the driven shaft 18 via the drive bearing 6. The drive shaft 17 and the driven shaft 18 are parallel to the upper horizontal tube 12 and the lower horizontal tube 15. The drive gear 7 is mounted on the drive shaft 17. The drive gear 7 meshes with the driven gear 22. An impeller 9 and a locking nut 10 are installed at the end of the drive shaft 17. The sleeve 4 is fixed on the lower horizontal tube 15 and fixed on the fixing column 2 by fixing screws 20. There are at least three sets of screw holes 19 in the height direction of the fixing column 2 and two sets of screw holes 19 in the height direction of the sleeve 4. Each set of screw holes 19 has at least three screw holes evenly distributed along the circumference. The fixing screws 20 are screwed into the above screw holes 19 to fix the sleeve 4 and the pump housing 21 in the required position.

[0025] A sampling port 11 is opened on the upper horizontal tube 12. A detector 23 is installed at the sampling port 11. The sensing probe 24 of the detector 23 is inserted into the bottom of the upper horizontal tube 12 to detect the pH value and temperature of the seawater pumped into the upper horizontal tube 12 in real time.

[0026] Seawater flows in the ditch, driving the impeller 9 to rotate. The rotation of the impeller 9 drives the drive shaft 17 and the drive gear 7 to rotate. Since the drive gear 7 and the driven gear 22 mesh, they drive the driven shaft 18 to rotate, causing the guide vanes 13 and the pump impeller 14 to rotate. Seawater enters the two sets of guide vanes 13 and pump impeller 14 sequentially from the bell mouth 3 and is then sucked into the pump casing 21. As the seawater continues to flow, the impeller 9 rotates continuously. Under the push of the guide vanes 13 and the pump impeller 14, fresh seawater flows through the lower end of the sampling port 11 and flows back into the seawater ditch. The sensor probe of the detector 23 can detect the temperature and pH value of the seawater in real time.

[0027] The components of the sampling device are made of fiberglass, plastic, or corrosion-resistant alloy.

[0028] Both the pump impeller 14 and the drive impeller 9 are axial flow impellers. They can consist of two or more stages; increasing the number of impeller stages can increase the seawater lifting height of the sampling device. As the number of pump impellers 14 increases, the number of stages of the guide vanes 13 also increases accordingly.

[0029] The detector 23 and the sampling port 11 are located on the ground or above the platform to facilitate manual sampling and inspection and maintenance of the detector 23.

[0030] A sealing strip (not shown) is installed between the driving bearing 6 and the driven bearing 8 and the longitudinal tube 16 to prevent seawater from flowing out.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made to the technical content of this utility model without departing from the spirit of this utility model.
