Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a cleaning mechanism and a pumping device. Background Technology

[0002] The water flow gauge is a key device for monitoring seepage flow in the grouting gallery and traffic corridor of concrete dams. It collects data by measuring the displacement of a float on a magnetic rod, and its accuracy is directly related to the dam safety assessment results.

[0003] Prolonged exposure to hard water can cause calcification and deposition in key components of the water meter. Calcification increases the mass of the float, alters the buoyancy balance, and the calcium layer hinders the float's displacement, resulting in data distortion. Traditional cleaning methods rely on physical scraping tools such as knives and shovels, which cannot reach the dead corners inside the float. Manual cleaning is time-consuming, and metal tools can easily scratch the float or deform the magnetic rod. Summary of the Invention

[0029] Example 1

[0030] Reference Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a cleaning mechanism, including a reaction tube 1 and an installation unit 2, including a reaction space 21 provided in the reaction tube 1 to contain a weak acid liquid, and a reaction element 22 disposed on the reaction tube 1.

[0031] Specifically, the reaction tube 1 is composed of a first tube 12 and a second tube 13 connected axially along the same side by a stainless steel hinge 14. The hinge 14 allows the two tubes to open and close relative to each other, with a maximum opening angle of 180 degrees. Inside the reaction tube 1, a reaction space 21 is formed to contain the weak acid liquid and enclose the float. The top opening 11 is located at the top of the reaction tube 1 to discharge the gas generated by the chemical reaction during the cleaning process. The bottom sealing structure ensures that the cleaning liquid will not leak.

[0032] An annular protrusion 24 is located on the inner wall of the middle section of the reaction tube 1, i.e., in the middle of the tube body. Its shape matches the outer contour of the lower half of the float. Its function is to position and accommodate the float, ensuring that the float remains centered within the tube body. More importantly, a special gap is formed between the annular protrusion 24 and the outer wall of the float, which allows liquids such as oxalic acid solution to effectively penetrate into the narrow gap between the inner wall of the float and the magnetic rod, thereby dissolving the deposited scale. The inner diameter of the reaction tube 1 must be larger than the diameter of the magnetic rod inside the float to facilitate the insertion of the magnetic rod.

[0033] A silicone sealing strip 15 is provided on the inner wall of the first tube 12; correspondingly, a circumferential groove 16 is provided on the inner wall of the second tube 13. When the first tube 12 and the second tube 13 are closed, the sealing strip 15 is embedded in the groove 16, forming an effective radial seal to prevent liquid leakage. This ensures that liquid does not leak during the cleaning process.

[0034] The liquid addition funnel 221 is located outside the first tube 12 near its upper end. To facilitate liquid injection and reduce air bubbles, this is the inlet for injecting the weak acid cleaning solution and subsequent clean water into the reaction space 21. The drain pipe 222 is located outside the first tube 12 near its lower end, at the very bottom of the reaction space 21. This is the channel for discharging waste liquid and cleaning solution. A stop valve 223 is installed on the drain pipe 222 to control the opening and closing of the pipeline. It remains closed during the liquid injection and reaction stages and opens when draining waste liquid.

[0035] Two fastening sleeves 23 are respectively fitted onto the upper and lower ends of the reaction tube 1, and are made of highly elastic rubber. After the reaction tube 1 is closed, the sleeves slide to the working position, and the elastic contraction force of the rubber generates a radial sealing force to tighten the tube body, effectively preventing the first tube 12 and the second tube 13 from accidentally opening under hydraulic pressure or during operation. On the other hand, it can also further tighten the fit between the sealing strip 15 and the groove 16, significantly enhancing the sealing performance of the entire reaction space 21. They are very easy to install and remove; simply "slide away" or "slide back" from the end of the reaction tube 1 to detach or fix them in place.

[0036] The syringe 3 is connected to the drain pipe 222 via the flexible conduit 31 at its end. The diameter of the opening of the flexible conduit 31 must be smaller than the diameter of the opening of the drain pipe 222 in order to facilitate a reliable connection.

[0037] During use, hold the two fastening sleeves 23 at the upper and lower ends of the reaction tube 1 respectively, gently rotate and slide them away from the middle working section of the reaction tube 1 along the axial direction, so that it is completely removed from that area. Temporarily place it in a safe position, hold the non-hinge 14 side of the first tube 12 and the second tube 13 with both hands respectively, and smoothly open the two tubes to an angle of about 120° along the axis of rotation of the stainless steel hinge 14. This opening angle or the inside of the second tube 13 ensures that the float is placed in the middle section of the reaction tube 1, so that it is completely seated in the annular protrusion 24. The purpose is to ensure that the gap formed between the annular protrusion 24 and the outer wall of the float is uniform, so that the oxalic acid solution injected later can penetrate evenly and effectively into the narrow dead corner between the inner diameter of the float and the magnetic rod through this gap, and completely dissolve stubborn scale.

[0038] After placement, close the two tubes together, apply uniform force to the reaction tube 1, and completely close the first tube 12 and the second tube 13 along the hinge 14 axially. Ensure that the silicone sealing strip 15 is embedded in the slot 16 when fully closed. Slide the two previously slid-out rubber fastening sleeves 23 back to the outside of the reaction tube 1 from both ends along the axial direction. Relying on the elasticity and toughness of the rubber itself, the fastening sleeves 23 will tighten the upper and lower ends of the reaction tube 1. The radial sealing force generated at this time plays two key roles: first, it provides additional pressure to firmly press the two tubes together, preventing them from opening on their own under the action of liquid or operational vibration; second, it further tightens the contact between the sealing strip 15 and the slot 16, making the entire reaction space 21 a highly sealed space, effectively preventing the leakage of cleaning fluid.

[0039] 200 ml of oxalic acid solution is poured into the tilted funnel 221. The target liquid level should completely submerge the annular protrusion 24 in the middle section of the reaction tube 1, ensuring that the float is completely immersed in the solution. The oxalic acid solution fills the entire reaction space 21, efficiently penetrating into the hard-to-reach dead zone between the inner wall of the float and the magnet. Oxalic acid reacts rapidly with calcium carbonate, producing soluble calcium oxalate, carbon dioxide gas, and water.

[0040] After the liquid injection is completed, allow reaction tube 1 to stand for at least 30 minutes. During this time, the oxalic acid solution will continuously dissolve the scale on the outer surface of the float, the dead corners of the inner wall, and the surface of the magnetic rod. The reaction gas will overflow from the top opening 11.

[0041] After the reaction has completed, prepare to remove the waste liquid. First, connect the end of the PVC flexible tube 31 at the tip of syringe 3 to the outer end of drain pipe 222, and unscrew the stop valve 223 installed on drain pipe 222. At this time, the waste liquid in reaction space 21 will begin to flow towards flexible tube 31 by gravity. Use syringe 3 to perform an aspiration action. The negative pressure generated when the piston is pulled back will help to draw the waste liquid in reaction space 21 as thoroughly as possible through drain pipe 222 and flexible tube 31 into syringe 3. Repeat the aspiration several times to empty the waste liquid as much as possible.

[0042] Keeping reaction tube 1 closed, inject clean water into reaction space 21 again through addition funnel 221. The amount injected should be sufficient to effectively flush the entire space and the surface of the float. Close stop valve 223, manually shake or gently vibrate reaction tube 1 to allow clean water to flow inside and flush away residual acidic substances and dissolved substances.

[0043] Open the stop valve 223, reconnect the flexible tubing 31 and syringe 3, and perform the aspiration and drainage operation. This completes one flushing cycle. After confirming that the last rinse waste liquid is basically neutral and the drainage is complete, loosen and slide the rubber fastening sleeves 23 at the upper and lower ends respectively. Hold the non-hinge 14 side of the tube body and open the first tube 12 and the second tube 13 along the hinge 14 axis. Remove the cleaned float from the opened tube body.
