Description

Technical Field

[0001] This utility model relates to the field of level gauges, and in particular to solution level gauges. Background Technology

[0002] A lithium bromide solution level gauge is an instrument used to measure the liquid level in containers storing or transporting lithium bromide solution. It converts the liquid level signal into a readable value or signal through a specific sensing principle, so as to realize the monitoring and control of the solution volume and ensure the safe and stable operation of related equipment.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN219265448U, a solution level gauge is disclosed. It uses the inflation of the expansion bladder to make the plug tightly fixed to the mouth of the solution tank, and uses the buoyancy plate to drive the depth rod to slide in the smooth sleeve. Combined with the lens, the liquid level is displayed in real time, which improves corrosion resistance and service life. However, in actual use, it has been found that because the lithium bromide solution itself has a concentration, and the high concentration solution shakes when the solution is added or removed, it has a significant impact on the float. The swaying float cannot effectively display the liquid level. In addition, the lithium bromide solution needs to ensure the sealing of the tank body to avoid gaps caused by the vertical rod in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a solution level gauge to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0007] The stretching assembly includes a sealing box, a pull rope, and a sealing plug. The sealing box contains a winding assembly and a torque assembly that drives the winding assembly to tighten elastically. The winding assembly is connected to the float of the bottom floating assembly via the pull rope. A sealing plug is provided at the bottom opening of the sealing box, and the pull rope passes through and connects to the sealing plug.

[0008] The floating assembly also includes a limiting rod and a limiting groove. The limiting rod has a U-shaped structure, and the float is slidably connected to the inner side of the limiting rod. The float has a limiting groove formed on it to match the limiting rod. The float is made of glass.

[0009] The winding assembly includes a spline shaft and a winding rod. The pull rope is wound around the outside of the spline shaft. The winding rod is inserted into the spline shaft and slidably connected to the spline shaft through a spline groove. An encoder is connected to one end of the spline shaft.

[0010] Preferably, the torque assembly includes a screw, a torque sleeve, and a torsion spring. One end of the torque sleeve is fixed to the rope take-up rod, and the end of the torque sleeve away from the rope take-up rod is threaded to the screw. The end of the screw away from the torque sleeve is fixed to the sealing box, and the middle part of the torque sleeve is connected to the inner wall of the sealing box through the torsion spring.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-5 As shown, the solution level gauge includes a floating assembly 2 for detecting the liquid level and a tension assembly 3 for cooperating with the floating assembly 2 to ensure sealing and protection. The top of the floating assembly 2 is connected to the tension assembly 3, and the tension assembly 3 is installed inside the sealing cover 1.

[0030] The tensioning component 3 includes a sealing box 31, a pulling rope 32, and a sealing plug 33. The sealing box 31 is equipped with a winding component and a torque component that drives the winding component to tighten elastically. The winding component is connected to the float 22 of the bottom floating component 2 through the pulling rope 32. The sealing box 31 has a sealing plug 33 at the bottom opening, and the pulling rope 32 passes through and connects to the sealing plug 33.

[0031] The floating component 2 also includes a limiting rod 21 and a limiting groove 23. The limiting rod 21 has a U-shaped structure, and the float 22 is slidably connected to the inner side of the limiting rod 21. The float 22 has a limiting groove 23 formed on it to match the limiting rod 21. The float 22 is made of glass.

[0032] The winding assembly includes a spline shaft 44 and a winding rod 45. The pull rope 32 is wound around the outside of the spline shaft 44. The winding rod 45 is inserted into the spline shaft 44 and is slidably connected to the spline shaft 44 through a spline groove. An encoder 46 is connected to one end of the spline shaft 44.

[0033] In this embodiment, the torque assembly includes a screw 41, a torque sleeve 42, and a torsion spring 43. One end of the torque sleeve 42 is fixed to the receiving rope rod 45, and the end of the torque sleeve 42 away from the receiving rope rod 45 is threadedly connected to the screw 41. The end of the screw 41 away from the torque sleeve 42 is fixedly connected to the sealing box 31. The middle part of the torque sleeve 42 is connected to the inner wall of the sealing box 31 through the torsion spring 43. When the float 22 is supported by the buoyancy of the lithium bromide solution, the pull rope 32 loses the tension of the bottom float 22. At this time, the receiving rope rod 45 is subjected to the torque of the torsion spring 43, and the rotation of the receiving rope rod 45 drives the pull rope 32 to tighten. Simultaneously, the rotation of the receiving rope rod 45 drives the encoder 46 to detect the height of the lithium bromide solution level through the spline shaft 44.

[0034] In this embodiment, the torsion of the torsion spring 43 is less than the weight of the float 22.

[0035] In this embodiment, the sealing cap 11 is connected to the external tank via threads to ensure the tank's airtightness.

[0036] In this embodiment, the limiting rod 21 is coated with an anti-corrosion coating.

[0037] In this embodiment, the sealing box 31 is connected to the empty groove at the bottom of the sealing cover 11 by sealing adhesive, and the encoder 46 is embedded in the inside of the sealing cover 11.

[0038] In this embodiment, the width of the limiting groove 23 is greater than the diameter of the limiting rod 21, and the corners of the limiting groove 23 are all rounded to reduce the friction between the limiting rod 21 and the float 22.

[0039] Working principle: The sealing cap 11 is fixed to the top of the tank by threads. At this time, the float 22 will be pulled by gravity and the pulling rope 32 will move downward. The shock-absorbing pad at the bottom of the float 22 ensures the safety of the float 22. Lithium bromide solution is injected into the tank. When the solution is injected, the movement of the solution will impact the float 22. However, because the float 22 is restricted by the limiting rod 21, there will be no shaking in the end face, only up and down movement.

[0040] When the liquid level changes, if the solution increases, the pull rope 32 loses the tension of the bottom float 22. At this time, the take-up rod 45 is subjected to the torque of the torsion spring 43, and the rotation of the take-up rod 45 drives the pull rope 32 to tighten. Simultaneously, the rotation of the take-up rod 45 drives the encoder 46 to detect through the spline shaft 44, and records through the controller 12 (the communication method between the encoder 46 and the controller 12 is a common control method in existing equipment, which will not be described in detail here). This detects the height of the lithium bromide solution level. When the torsion spring 43 and the torsion sleeve 42 rotate, the threaded groove inside the torsion sleeve 42 cooperates with the thread on the screw 41, causing the torsion sleeve 42 and the take-up rod 45 to move towards the torsion sleeve 42. Thus, when the pull rope 32 is wound, the winding trajectory on the take-up rod 45 is spiral-shaped, avoiding knotting.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
