[0026] Embodiment 1:

[0027] like Figure 1 to Figure 2 As shown, a schematic diagram of an embodiment of a liquid level detection device of the present invention includes a measuring component and a positioning component, the positioning component includes a first positioning component 3 set at the measuring position, the measuring component includes a measuring rod 1 and a floating component 2 connected to the measuring rod 1, and the measuring rod 1 is slidably connected to the first positioning component 3. In this embodiment, the first positioning component 3 and the measuring rod 1 are arranged perpendicular to each other. The floating component 2 is made of a material with a density lower than that of the liquid to be detected, and is usually used for water level detection, so the floating component 2 is mostly made of a material with a density lower than that of water. The measuring rod 1 is made of a waterproof material and is a hollow tube to reduce the weight. For example, a hollow plastic tube is used, which can not only meet the use requirements, but also has a light weight and low production cost. In this embodiment, the measuring rod 1 is floated on the liquid surface 91 by the floating component 2, and then the measuring rod 1 is supported in the horizontal direction by the positioning component fixed at the measuring position. The detection personnel can quickly detect the liquid level change through the relative position of the measuring rod 1 and the positioning component without inserting into the pipe, which can ensure both safe detection and accurate detection. It can be applied to various liquid level detection in pipelines, and the installation is simple and convenient, and the detection efficiency is high.

[0028] In this embodiment, the measuring rod 1 is provided with scale lines along its length. During detection, personnel can quickly determine the change in the distance from the floating member 2 to the positioning component by measuring the scale change at the junction of the measuring rod 1 and the positioning component, that is, determine the change in the water level in the pipe 9.

[0029] In this embodiment, the measuring component also includes a top cap 5, which is connected to the measuring rod 1 to prevent slipping. This design can better prevent the measuring rod 1 from slipping due to a rapid drop in water level due to special reasons during the closed water test, thereby ensuring the service life of the measuring rod 1 and preventing the detection tool from falling into the pipe and affecting the internal environment of the pipe. In this embodiment, the top cap 5 is detachably connected to the measuring rod 1, so that the measuring rod 1 is detachably connected to the first positioning member 3. This design facilitates the repair and maintenance of the liquid level detection device, and can also facilitate the transportation and storage of the device after disassembly.

[0030] In this embodiment, the positioning component is retractable, and further includes a second positioning member 4 , which is movably connected to the first positioning member 3 .

[0031] In different embodiments, the number of the first positioning member 3 and the second positioning member 4 can be designed to include one or more according to the use requirements, such as the number of the first positioning member 3 and the second positioning member 4 are both one and they are movably connected to each other to adjust the extension and contraction, and the measuring rod 1 is inserted into the first positioning member 3; for another example, the number of the first positioning member 3 is still one, the number of the second positioning member 4 can be two and they are movably connected to the two ends of the first positioning member 3 respectively, and the measuring rod 1 is movably inserted into the middle of the first positioning member 3. The first positioning member 3 can be designed in a variety of ways according to the use requirements, and can be plate-shaped; in this embodiment, the first positioning member 3 is rod-shaped and the number is multiple, and the positioning component also includes a connecting member 6, which can be made of a sleeve, and multiple first positioning members 3 are connected to each other through the connecting member 6, and each first positioning member 3 is vertically connected to the connecting member 6, and the connecting member 6 is slidably connected to the measuring rod 1. In this embodiment, the measuring rod 1 is movably inserted into the connecting member 6, and the number of the second positioning members 4 is adapted to the number of the first positioning members 3. In this embodiment, each second positioning member 4 is movably arranged at the end of the corresponding first positioning member 3 away from the connecting member 6. A plurality of first positioning members 3 are evenly distributed around the connecting member 6 . In this embodiment, there are two first positioning members 3 symmetrically disposed on both sides of the connecting member 6 .

[0032] The positioning component also includes a plurality of clamping rods 7 for clamping, and each clamping rod 7 is designed to be connected to the first positioning member 3 or the second positioning member 4 in an L-shape according to the number and assembly method of the first positioning member 3 and the second positioning member 4. For example, when the number of the first positioning member 3 and the second positioning member 4 is one and they are movably connected to each other, the number of the clamping rods 7 can be two and they are respectively connected to the first positioning member 3 and the second positioning member 4 to form a retractable inverted U-shaped structure to be adjustably clamped at the pipe mouth; in this embodiment, the clamping rod 7 is only connected to the second positioning member 4 and is integrally formed to be manufactured as an L-shaped member that can be movably connected to the first positioning member 3.

[0033] In this embodiment, each first positioning member 3 and the second positioning member 4 can be movably connected by opening a plurality of adjustment holes on the second positioning member 4 and a limiting hole on the first positioning member 3. The positioning component also includes an adapted number of fastening bolt assemblies 8. The limiting holes correspond to the corresponding adjustment holes and are fixed by the bolt assemblies 8.

[0034] On the other hand, the present invention also provides a method for using the liquid level detection device, comprising the following steps:

[0035] When conducting a closed water test, the measuring rod 1 is passed through the connecting piece 6 and the top cap 5 is installed. The second positioning piece 4 is adjusted to fix the positioning component at the measuring position. During adjustment, the second positioning piece 4 can be moved to the fitting position and fixed by the bolt assembly 8 so that the positioning component is adapted to the size of the pipe 9 and is clamped to the pipe mouth by the clamp rod 7. The measuring rod 1 can float on the liquid surface 91 through the floating piece 2. The floating piece 2 allows the measuring rod 1 to float with the change of the liquid surface 91 and is horizontally supported by the positioning component. The change in the distance from the floating piece 2 to the positioning component can detect the change in water level. In this embodiment, the value can be directly read through the scale line. The detection personnel record the measured values ​​in sequence according to the requirements of different time intervals to compare the water level changes. This method can improve the detection accuracy and efficiency and facilitate operation.

[0036] This embodiment can quickly detect water level changes when conducting a closed water test on the pipeline, without the need for personnel to reach into the pipeline for inspection, thereby ensuring the safety of the inspection process; the retractable and adjustable positioning component can not only shrink to reduce the occupied space during storage or transportation, but can also be adapted to various pipe diameter inspections to ensure inspection stability, while having wide applicability and can be promoted for use; the structure is simple and easy to operate, which can ensure the construction inspection cost and inspection quality and avoid manual measurement errors by different personnel.

[0037] Embodiment 2:

[0038] like Figure 3 As shown, in this embodiment, a lighting component 10 is also included, and the lighting component 10 is connected to the first positioning member 3. More specifically, compared with embodiment 1, in this embodiment, the lighting component 10 is installed on the connecting member 6. The lighting component 10 can be made of an LED lamp or a fluorescent ring, etc., which is better suitable for detection at night or in poor light environments. The lighting technology and specific assembly method are prior art and are not described separately in the present invention.

[0039] In this embodiment, the top cap 5 may also be provided with a lifting ring 11 to facilitate operation or transportation.

[0040] This embodiment is more suitable for complex detection environments such as dark light, is easy to operate, and can ensure detection accuracy.
