[0002] Submersible level gauges are widely used in water level measurement scenarios in pools and tanks, such as measuring the water level in waste heat recovery tanks. They are indispensable sensors in water level data acquisition systems and automatic hydrological monitoring systems. During actual measurement, water bodies are easily disturbed by external factors such as water inflow, causing water accumulation and severely affecting the accuracy of the measurement. Therefore, submersible level gauges are typically installed and fixed using hooks. However, due to the limitations of the submersible level gauge's structural design, it cannot be applied to the installation and measurement of different types of scenarios, affecting the stability of water level measurements. Utility Model Content

[0010] In some embodiments, the first telescopic member is provided with a first limiting protrusion, which abuts against the side of the mounting member opposite to the first limiting groove.

[0011] In some embodiments, the submersible water level gauge further includes a plurality of second snap-fit ​​components, each of which includes a second elastic element and a second snap-fit ​​element.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0022] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0027] In some embodiments, please refer to Figure 1 This application provides an immersion water level gauge 100, which includes: a water level gauge device 10; and an installation device 20, including an installation member 21 and two locking components 30. The water level gauge device 10 is fixed on the installation member 21, and the two locking components 30 are respectively located on opposite sides of the water level gauge device 10. Each locking component 30 is disposed on the installation member 21 and is used to lock onto the inner wall of the measurement scene. At least one of the two locking components 30 can be adjusted along the length direction of the installation member 21.

[0028] The aforementioned submersible water level gauge 100 allows the water level gauge device 10 to be deployed into the measurement scenario, facilitating contact between the water level gauge device 10 and the water level in the test scenario to obtain water level information. Since at least one of the two locking components 30 can be adjusted along the length of the mounting member 21, the locking component 30 can be moved according to different specifications of the test scenario, ensuring that the locking component 30 is stably locked to the inner wall of the measurement scenario. This guarantees stable installation of the water level gauge device 10, enabling it to stably measure water level information and thus improving the stability of water level measurement.

[0029] It should be noted that, of the two locking components 30, one locking component 30 can be in an adjustable state, while the other locking component 30 can be in a fixed state; or, both locking components 30 can be in an adjustable state. When the submersible level gauge 100 is placed in a test scenario, such as in a waste heat recovery water tank, the locking component 30 can be moved along its length to reach a suitable position, thereby enabling the submersible level gauge 100 to be installed and measured in test scenarios of different specifications.

[0030] There are several ways to install the locking assembly 30 on the mounting part 21. For example, the locking assembly 30 can be installed in different positions by means of pin connection; or the locking assembly 30 can be installed on the mounting part 21 by means of a slide rail or other structure; or the locking assembly 30 can be installed on the mounting part 21 by means of a screw mechanism, etc.

[0031] Further, please refer to Figure 2Each locking assembly 30 includes a fixing frame 31 and a locking member 32. The fixing frame 31 includes a connecting plate 312 and a limiting plate 313 and a fixing plate 311 spaced apart on the connecting plate 312. The connecting plate 312 is located on the mounting member 21. The locking member 32 is screwed to the fixing plate 311, and one end of the locking member 32 is used to engage with the limiting plate 313 to the inner wall of the measurement scene. During installation, the connecting plate 312 is moved to position the locking assembly 30 as required. Then, the locking member 32 is rotated so that one end of the locking member 32 moves towards the limiting plate 313, thereby engaging with the limiting plate 313 to engage with the inner wall of the measurement scene, such as the top of a waste heat recovery water tank, thus achieving rapid installation.

[0032] It should be noted that the connecting plate 312 is movably mounted on the mounting part 21. For example, the connecting plate 312 can be mounted on the mounting part 21 via a slide rail or other structure; or, the connecting plate 312 can have a through hole through which it fits onto the mounting part 21. Meanwhile, the limiting plate 313 and the fixing plate 311 are spaced apart on the connecting plate 312, and their mounting methods can be varied. For example, both the limiting plate 313 and the fixing plate 311 can be fixed to the connecting plate 312 by bolts, snap-fitting, riveting, welding, or bonding; or, the limiting plate 313, the fixing plate 311, and the connecting plate 312 can be designed as an integrated structure.

[0033] In some embodiments, please refer to Figure 2 The water level gauge device 10 includes a water level gauge body 11, a telescopic component 12, and a protective body 13. The water level gauge body 11 and the telescopic component 12 are spaced apart on the mounting member 21. One end of the water level gauge body 11 and one end of the telescopic component 12 are both inserted into the protective body 13. The telescopic component 12 is connected to the inner wall of the protective body 13 and is configured to extend and retract along its own length. It can be seen that by extending and retracting the telescopic component 12, the protective body 13 can be adjusted according to the length of the water level gauge body 11 to achieve better protection. Simultaneously, since one end of the telescopic component 12 and one end of the water level gauge body 11 are both inserted into the protective body 13, the protective body 13 can also protect one end of the telescopic component 12.

[0034] Furthermore, during water level monitoring, the protective structure 13 effectively suppresses the impact of external factors such as water inflow disturbances and water flow impacts on the internal water body. Even in the event of severe external water level fluctuations, the protective structure 13 can control the fluctuation amplitude of the internal water surface to a very small range, virtually eliminating the interference of water flow on the measurement reference surface. Thus, this stable water environment ensures the high stability of the water level measurement reference surface, providing a solid physical foundation for achieving high-precision water level data acquisition.

[0035] It should be noted that the protective body 13 refers to a structure that protects one end of the water level gauge body 11, and it can be a box-shaped, tubular, or cylindrical structure. Meanwhile, the water level gauge body 11 refers to the structure capable of acquiring water level information within the measurement scenario, and it can be, but is not limited to, an ultrasonic water level gauge. To facilitate measurement by the water level gauge body 11, a water inlet 134 can be provided at the bottom of the protective body 13. Water can then enter the protective body 13 through the water inlet 134, and the siphon effect of the bottom water inlet 134 will cause the water level inside the protective body 13 to gradually rise until it is level with the external water surface, so that the water level gauge body 11 can accurately acquire water level information.

[0036] In addition, the protective body 13 is connected to one end of the telescopic component 12 in various ways, such as, but not limited to, bolt connection, snap-fit, riveting, welding, etc.

[0037] It should also be noted that the number of telescopic components 12 can be one or more. In some specific examples, the number of telescopic components 12 is two, and the protective body 13 is fixed to the mounting member 21 by the two telescopic components 12.

[0038] Further, please refer to Figure 3 The telescopic assembly 12 includes a housing 121 and a first telescopic member 122 and a second telescopic member 123 slidably fitted within the housing 121. The first telescopic member 122 and the second telescopic member 123 move and adjust within the housing 121. One end of the first telescopic member 122 is engaged with the mounting member 21, and one end of the second telescopic member 123 is engaged with the inner wall of the protective body 13. During installation, the first telescopic member 122 and the second telescopic member 123 move within the housing 121, extending from both ends of the housing 121. Once the first telescopic member 122 and the second telescopic member 123 have extended to the appropriate positions, the first telescopic member 122 is engaged with the mounting member 21, and then one end of the second telescopic member 123 is engaged with the protective body 13, allowing for rapid assembly of the submersible level gauge 100 and improving assembly efficiency.

[0039] When the length of the water level gauge body 11 changes, the first telescopic member 122 and the second telescopic member 123 can be moved to change the length of the first telescopic member 122 and the second telescopic member 123 extending out of the outer shell 121, so that the position of the protective body 13 can be effectively adjusted, thereby making the protective body 13 better protect one end of the water level gauge body 11.

[0040] Furthermore, please refer to Figure 3The submersible water level gauge 100 also includes a first snap-fit ​​assembly 40, which includes a first elastic member 42 and a first snap-fit ​​member 41. One end of the first telescopic member 122 has a first moving groove 12c. The first snap-fit ​​member 41 is disposed in the first moving groove 12c through the first elastic member 42, and the first snap-fit ​​member 41 can extend or retract into the first moving groove 12c. The mounting member 21 has a first through hole 211 and a first limiting groove 212 that are interconnected. The first snap-fit ​​member 41 snaps into the first limiting groove 212. Thus, during the snap-fit ​​process, one end of the first telescopic member 122 can be inserted into the first through hole 211, so that the first snap-fit ​​member 41 is squeezed by the hole wall of the first through hole 211 and retracts into the first moving groove 12c; as the insertion continues, the first snap-fit ​​member 41 moves out of the first through hole 211 and into the first limiting groove 212. At this time, the first snap-fit ​​member 41 is not squeezed by the hole wall of the first through hole 211. Under the action of the first elastic member 42, it extends out of the first moving groove 12c and snaps into the first limiting groove 212 to achieve quick snap-fit.

[0041] In addition, while achieving rapid engagement, the compression and rebound of the first elastic element 42 can absorb vibration energy and suppress the shaking of the first engagement assembly 40.

[0042] It should be noted that, to facilitate the insertion of the first snap-fit ​​member 41 into the first through hole 211 and its pressing into the first moving groove 12c, the surface of the first snap-fit ​​member 41 can be designed as a curved surface. Simultaneously, to achieve stable engagement, there can be two first snap-fit ​​members 41, connected by a first elastic member 42. When one end of the first telescopic member 122 is inserted into the first through hole 211, the wall of the first through hole 211 presses against the two first snap-fit ​​members 41, causing them to elastically retract into the first moving groove 12c. When one end of the first telescopic member 122 extends out of the first through hole 211, the two first snap-fit ​​members 41, under the action of the first elastic member 42, extend out of both ends of the first moving groove 12c and engage in the first limiting groove 212.

[0043] Optionally, the first elastic element 42 may be, but is not limited to, a spring, elastic rubber, etc.

[0044] In some embodiments, please refer to Figure 3 The first telescopic member 122 is provided with a first limiting protrusion 12d, which abuts against the side of the mounting member 21 facing away from the first limiting groove 212. In this way, the first limiting protrusion 12d is introduced so that it cooperates with the first snap-fit ​​member 41 and is stably snapped onto the mounting member 21.

[0045] In some embodiments, please refer to Figure 4The submersible water level gauge 100 also includes multiple second snap-fit ​​components 50. Each second snap-fit ​​component 50 includes a second elastic element 52 and a second snap-fit ​​element 51. One end of the second telescopic member 123 has multiple second moving grooves 12e along its own length direction. The second snap-fit ​​element 51 is disposed in the second moving groove 12e through the second elastic element 52, and the second snap-fit ​​element 51 can extend or retract into the second moving groove 12e. The inner wall of the protective body 13 is provided with a connecting block 131. The connecting block 131 is provided with a second through hole 132 and multiple second limiting grooves 133 communicating with the second through hole 132. Each second snap-fit ​​element 51 snaps into the corresponding second limiting groove 133. It can be seen that during the snap-fit ​​process, one end of the second telescopic member 123 is inserted into the second through hole 132, and the hole wall of the second through hole 132 presses the second snap-fit ​​element 51 into the second moving groove 12e. When the second latching member 51 reaches the first second limiting groove 133, the second latching member 51 is ejected from the second moving groove 12e under the action of the second elastic member 52 and latches into the second limiting groove 133 to achieve initial latching and locking. When one end of the second telescopic member 123 continues to be inserted into the second through hole 132, the two second latching members 51 will be squeezed by the hole wall of the second through hole 132 and retract into the corresponding second moving groove 12e; when the two second latching members 51 move to the corresponding second limiting groove 133 respectively, the two second latching members 51 are respectively latched into the two second limiting grooves 133 to achieve double-layer latching and locking, ensuring that the second latching assembly 50 still maintains reliable connection under complex working conditions, avoiding the protective body 13 from slipping off the second telescopic member 123 due to external force, and improving the stability of the structure.

[0046] In addition, while achieving rapid engagement, the compression and rebound of the second elastic element 52 can absorb vibration energy and suppress the shaking of the second engagement assembly 50.

[0047] It should be noted that, to facilitate the insertion of the second snap-fit ​​member 51 into the second through hole 132 and its pressing into the second moving groove 12e, the surface of the second snap-fit ​​member 51 can be designed as a curved surface. Simultaneously, to achieve stable engagement, the number of second snap-fit ​​members 51 can be two, connected by a second elastic member 52. When one end of the second telescopic member 123 is inserted into the second through hole 132, the wall of the second through hole 132 presses against the two second snap-fit ​​members 51, causing the second snap-fit ​​members 51 to elastically retract into the second moving groove 12e. When one end of the second telescopic member 123 extends out of the second through hole 132, the two second snap-fit ​​members 51, under the action of the second elastic member 52, extend out of both ends of the second moving groove 12e and engage in the second limiting groove 133.

[0048] Optionally, the second elastic element 52 may be, but is not limited to, a spring, elastic rubber, etc.

[0049] In some embodiments, please refer to Figure 4 The second telescopic member 123 is provided with a second limiting protrusion 12f, which is located on one side of each second moving groove 12e and abuts against the side of the connecting block 131 facing away from the second limiting groove 133. In this way, the second limiting protrusion 12f is introduced so that it cooperates with the second snap-fit ​​member 51 and is stably snapped onto the mounting member 21.

[0050] In some embodiments, please refer to Figure 5 The inner wall of the outer casing 121 is provided with a guide rail 12a extending along its own length. Both the first telescopic member 122 and the second telescopic member 123 are provided with a moving block 124, which is slidably disposed on the guide rail 12a. In this way, the cooperation between the guide rail 12a and the moving block 124 ensures that the movement of the first telescopic member 122 and the second telescopic member 123 is more stable.

[0051] It should be noted that there are various ways to cooperate between the guide rail 12a and the moving block 124. For example, the surface of the moving block 124 can be provided with a dovetail groove or a T-shaped groove.

[0052] In some embodiments, please refer to Figure 3 It also includes fasteners 125. Locking holes 12b are provided at both ends of the outer casing 121. The fasteners 125 pass through the locking holes 12b to fix the first telescopic member 122 or the second telescopic member 123 inside the outer casing 121. It can be understood that when the position of the first telescopic member 122 or the second telescopic member 123 is adjusted to a suitable position, the fasteners 125 can be inserted into the locking holes 12b and abut against the first telescopic member 122 or the second telescopic member 123 to achieve stable fixation. The locking holes 12b can be threaded holes.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
