Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, and in particular to an immersion liquid level gauge resistant to water flow impact disturbance. Background Technology

[0002] Submersible level gauges are common liquid level measuring instruments. They measure liquid level by partially or fully immersing themselves in liquid. The measurement is based on the principle that the hydrostatic pressure of the liquid is proportional to its height. In use, the probe is submerged into the container along with the vent cable. However, as liquid is poured into or drained from the container, the probe and vent cable swing, easily causing data drift in the level readings. Prolonged swinging can also accelerate damage to the probe or vent cable. How to use submersible level gauges to withstand the disturbances caused by water flow, extend their service life, and ensure the accuracy of data acquisition remains a major challenge for technicians.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide an immersion level gauge resistant to water flow impact and disturbance, in order to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively ensures the accuracy of data acquisition and extends its service life.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides an immersion level gauge resistant to water flow impact and disturbance, such as Figures 1-3As shown, the device includes: a first tube 1, a second tube 3, and a level gauge. The bottom of the first tube 1 is fixedly connected to the bottom of the liquid container 5 being measured. At least one set of first water inlets 2 is provided on the side wall of the first tube 1, arranged along the axial direction of the first tube 1. The bottom end of the second tube 3 extends into the first tube 1 and is fixedly connected to the bottom of the liquid container 5 being measured. At least one set of second water inlets 4 is provided on the side wall of the second tube 3, arranged along the axial direction of the second tube 3, and horizontally offset from the first set of water inlets 2. The level gauge is used to measure the liquid level within the second tube 3. Through the synergistic effect of the first tube 1 and the second tube 3, and the offset water inlet sets, a relatively stable measurement environment is created for the level gauge. The fixed connection between the first tube 1 and the second tube 3 ensures the overall stability of the device and prevents displacement due to water flow. The arrangement of two sets of first inlet holes and four sets of second inlet holes allows water to gradually enter the inner pipe, avoiding direct impact of large amounts of water on the level gauge and reducing interference from water flow, thereby improving the accuracy of level measurement. The inlet hole groups in different directions guide the water flow in from different angles, further creating a stable measurement area.

[0026] In a preferred embodiment, the first pipe body 1 is provided with two sets of first water inlets 2, which are symmetrically arranged about the axis of the first pipe body 1. The second pipe body 3 is provided with two sets of second water inlets 4, which are also symmetrically arranged about the axis of the second pipe body 3. The symmetrical arrangement of the water inlets makes the water flow distribution around the pipe body more uniform. The water flow enters the pipe body from symmetrical positions, forming a relatively balanced water flow state within the pipe body. This avoids the level gauge from tilting or swaying due to uneven forces caused by excessive water flow on one side, further enhancing the stability and accuracy of the level gauge measurement. It also helps to balance the forces on the overall structure of the device.

[0027] In a preferred embodiment, the horizontal angle between the first group of water inlets 2 and the second group of water inlets 4 is 90°. This 90° angle further alters the path and direction of the water flow. When the water enters from the first group of water inlets 2, it passes through the second group of water inlets 4 at a 90° angle, resulting in a significant change in the water flow direction. This allows the water to be more fully dispersed, breaking the original impact tendency of the water flow. Consequently, it more effectively reduces the impact force of the water flow on the level gauge, making the liquid environment around the level gauge more stable and improving the accuracy and reliability of level measurement.

[0028] In a preferred embodiment, the first water inlet holes 2 in the first group of water inlets 2 are uniformly arranged in the axial direction of the first pipe body 1. The uniform arrangement of the first water inlet holes 2 ensures that the water flow entering the first pipe body 1 is evenly distributed axially. This helps to avoid excessive water flow concentration in a certain section, preventing strong pressure differences caused by excessive local water flow, which could lead to uneven local stress on the level gauge. The uniform water inlet distribution makes the water flow around the level gauge more stable, further ensuring the stability of the level measurement.

[0029] In a preferred embodiment, each of the second water inlet holes 4 in the second group of water inlets 4 is uniformly arranged in the axial direction of the second pipe body 3. The uniform arrangement of the second water inlets 4 in the axial direction of the second pipe body 3 ensures that the water flow after passing through the first pipe body 1 can be uniformly distributed again when entering the second pipe body 3. This is crucial for further stabilizing the water flow environment around the level gauge, effectively buffering the remaining water flow impact force, reducing the impact of water flow on the oscillation of the level gauge, and thus ensuring that the level gauge works stably and accurately.

[0030] In a preferred embodiment, the heights of both the first tube 1 and the second tube 3 are greater than the maximum range of the liquid level to be measured in the liquid container 5, ensuring that the level gauge remains within sufficient space throughout the measurement process and is unaffected by changes in liquid level. Regardless of whether the liquid level is low or near its maximum range, the first tube 1 and the second tube 3 effectively provide a stable protection zone for the level gauge, preventing changes in water flow impact as the liquid level rises near the top and affecting the stability of the level gauge measurement, thus ensuring accurate measurement under various liquid level conditions.

[0031] In a preferred embodiment, the first pipe body 1 and the second pipe body 3 are arranged coaxially. This coaxial arrangement ensures that the water flow is in a more ideal flow state when entering the second pipe body 3 from the first pipe body 1, reducing turbulence and energy loss caused by the misalignment of the pipe bodies. This helps maintain the dispersion effect of the water flow, making the overall water flow distribution more regular and stable, thereby improving the ability to suppress interference with the level gauge and creating a more ideal and stable measurement environment for the level gauge.

[0032] In a preferred embodiment, both the first tube 1 and the second tube 3 are made of stainless steel. The bottoms of both tubes are welded and fixed to the container 5 containing the liquid being measured. The use of stainless steel ensures the strength and corrosion resistance of the tubes, enabling stable use in various liquid environments for extended periods and extending the service life of the device. The bottom welding method enhances the stability of the connection between the tubes and the container 5, ensuring that the first tube 1 and the second tube 3 will not loosen due to water flow impact or vibration during long-term use. This provides a reliable support structure for the level gauge and ensures the long-term stability of the level measurement operation.

[0033] In a preferred embodiment, the diameter of the first tube 1 is 51 mm, and the diameter of the first inlet hole 2 is 30 mm. This specific combination of tube and inlet diameters, carefully designed and tested, ensures that the water flow entering the first tube 1 maintains a certain speed and dispersion effect while meeting the overall structural requirements of the device. This dimensional design ensures sufficient water flow into the first tube 1 while effectively dispersing water pressure. Further processing by subsequent structures creates a suitable liquid environment for the level gauge, achieving a good balance between resistance to water flow impact and accurate measurement.

[0034] In a preferred embodiment, the diameter of the second pipe body 3 is 32 mm, and the diameter of the second inlet hole 4 is 20 mm. This pipe diameter and inlet hole diameter setting cooperates with the first pipe body 1, allowing the water flow after preliminary treatment by the first pipe body 1 to enter the second pipe body 3 at a suitable speed and flow rate. The appropriate inner diameter ensures the stability of the water flow inside the second pipe body 3, and the smaller diameter of the second inlet hole 4 helps to further balance the water flow velocity and dispersion effect, ensuring that the water flow that finally enters the level gauge measurement area will not cause excessive impact on the level gauge, thereby improving the stability and accuracy of level measurement.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
