Description

Technical Field

[0001] This utility model relates to the field of hydrostatic leveling instruments, and in particular to a magnetostrictive hydrostatic leveling instrument. Background Technology

[0002] A hydrostatic level is a high-precision liquid level measuring device specifically designed for accurately monitoring subtle vertical displacement changes in structures, such as relative settlement, heave, and tilt, at multiple points. Hydrostatic levels are widely applicable to the vertical displacement and tilt monitoring of various engineering structures, including large storage tanks, dams, nuclear power plants, high-rise buildings, foundation pits, tunnels, bridges, and subways. Its working principle involves connecting multiple hydrostatic level containers via liquid-conducting pipes. When a structure settles, the liquid level at each measuring point changes accordingly, causing the position of a float on the liquid surface to shift. By accurately measuring the change in float position at each measuring point, the relative vertical displacement data between these points can be accurately obtained, allowing for in-depth analysis of the structure's settlement status.

[0003] In existing technologies, the inlet and outlet of most hydrostatic levels are far apart from each other and are located at the top and bottom of the main body.

[0020] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0021] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0022] Please see Figures 1-4This utility model discloses a magnetostrictive hydrostatic level, comprising a top cover 2, a shell 1, and a base 3 connected in sequence to form a first accommodating space, and a second accommodating space formed inside the base 3; the cylindrical surface of the base 3 has inlet and outlet ports 4 communicating with the first accommodating space; a main control board 8 is provided in the second accommodating space, and a measuring tube 6 wrapped with a waveguide and a float 7 are provided in the first accommodating space. One end of the measuring tube 6 is vertically and fixedly connected to the center of the base 3, and the measuring tube 6 passes through the base 3 and is electrically connected to the main control board 8, while the other end is vertically upward and placed in the first accommodating space, and the float 7 is slidably sleeved on the measuring tube 6; the cylindrical surface of the base 3 also has a wiring port 31 communicating with the second accommodating space; wherein, the inlet and outlet ports 4 are connected to an external liquid pipe to inject antifreeze into the first accommodating space and other hydrostatic instruments. The level instrument is connected; the static level instrument of this utility model adopts the arrangement mode of the inlet and outlet 4 and the electrical connection port 31 on the same side and on the same base, which greatly improves the convenience of water and line connection, while optimizing the overall appearance of the product, making the product look more beautiful and neat, and effectively avoiding the inconvenience caused by messy pipelines; the inlet and outlet 4 are connected to the external liquid pipe, and antifreeze is injected into the first accommodating space through the inlet and outlet 4. The float 7 is a magnetic ball. The measuring tube 6 is used to measure the liquid level height of the float 7 and convert it into a proportionally changing signal value. The liquid level height value of the float 7 is calculated based on the signal value, and then the relative liquid level change value between the point and the reference point is derived; the connection port 31 allows the main control board 8 in the second accommodating space of the base 3 to be electrically connected to the outside through wires.

[0023] In this embodiment, a waveguide is provided inside the measuring tube 6. The waveguide is electrically connected to the main control board 8. The waveguide is used to measure the liquid height in the first accommodating space. The difference between the initial liquid level height measured by the waveguide and the current liquid level height is used to intuitively determine the water level change difference. Furthermore, a connecting tube 12 is provided outside the housing 1. The connecting tube 12 is made of transparent material. The surface of the connecting tube 12 is provided with a range based on laser engraving. The range of the connecting tube 12 is consistent with the liquid level indication of the measuring tube inside the measuring tube 6. Specifically, it can be transparent PC. The connecting tube 12 supported by transparent PC not only has a clear and beautiful display effect, but also gives the product excellent durability. In addition, the range based on laser engraving on the surface of the connecting tube 12 ensures that the scale will never fade and remains clear and easy to read for a long time, providing users with reliable reading data.

[0024] In this embodiment, please refer to Figure 1 and Figure 4The top cover 2 is equipped with a level 9, which is used to assist in adjusting and installing the static level and to detect whether the measuring tube 6 is at a horizontal plane perpendicular to the liquid in the first accommodating space. Since the first accommodating space contains liquid, it is necessary to ensure that the static level is at a completely horizontal angle before liquid level detection to avoid affecting the measurement accuracy. The level 9 allows users to quickly calibrate the measuring tube 6 horizontally, ensuring that the measuring tube 6 is perpendicular to the liquid surface, effectively improving installation efficiency, reducing installation difficulty, and achieving a convenient installation experience that saves time and effort.

[0025] In this embodiment, the top cover 2 is also provided with a water inlet 10 that communicates with the first accommodating space. A plug 11 is embedded in the water inlet 10. The water inlet 10 is used to replenish liquid to the first accommodating space. The water inlet 10 facilitates the user to quickly add or drain liquid to the first accommodating space. At the same time, it can effectively solve the problem of blockage caused by long-term liquid deposition and ensure that the product always maintains a good working condition. By sealing or opening the water inlet 10 with the plug 11, liquid can be added to or drained from the first accommodating space at any time.

[0026] In this embodiment, a waterproof rubber ring is also fitted at the contact portion between the measuring tube 6 and the base 3. Since the waveguide inside the measuring tube 6 is electrically connected to the main control board 8, in order to prevent liquid in the first accommodating space from entering the second accommodating space through the gap between the measuring tube 6 and the base 3 and causing damage to the main control board 8, a waterproof rubber ring is fitted at the contact portion between the measuring tube 6 and the base 3 to improve the sealing and waterproof performance, and to avoid liquid penetration into the second accommodating space, which could lead to accidents such as short circuits or burnout of the main control board 8.

[0027] In this embodiment, the part of the housing 1 that mates with the top cover 2 is also provided with a vent hole. The vent hole is used to make the pressure in the first accommodating space equal to the external atmospheric pressure. By setting the vent hole, based on the principle of communicating vessels, the atmospheric pressure in the first accommodating space of each series-connected hydrostatic level is kept in balance. Based on this, it is possible to observe whether the horizontal liquid level of any hydrostatic level changes, and thus determine the settlement of the building.

[0028] The working principle of this utility model is as follows:

[0029] When using this product, first connect the liquid inlet and outlet pipes 4, connect multiple hydrostatic levels in series to form a connection, and inject coolant into the inlet and outlet pipes 4 of the first hydrostatic level. The main control board 8, which is housed in the second housing space, can be connected via wiring port 31 and lead out wiring from another wiring port 31 to other hydrostatic levels. Multiple hydrostatic levels are connected in series. Then, the level is calibrated by the level 9 embedded in the top cover 2 to ensure that the measuring tube 6 is perpendicular to the horizontal plane of the liquid in the first housing space, so as to avoid the measurement results being affected by slight tilt. After powering on, the magnetostrictive level gauge in the measuring tube 6 senses the height of the float 7 due to the injected coolant, accurately calculates the liquid level change surface of the liquid surface where the float 7 is located, and observes the liquid level height difference at this time according to the range on the connecting pipe 12.

[0030] The advantages of this utility model are:

[0031] The static level of this utility model adopts a layout where the water inlet and outlet are on the same side and the electrical wiring port is on the same base, which greatly improves the convenience of water and electrical connection. At the same time, it optimizes the overall appearance of the product, making the product look more beautiful and neat, and effectively avoids the inconvenience caused by messy pipelines.

[0032] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
