[0002] In existing technologies, after the construction of indoor drainage pipes is completed, a water tightness test is required. Typically, according to specifications, the pipes need to be filled with water, and any changes in the water level are observed to determine if there are any leaks or seepage. However, in actual engineering projects, due to the communicating vessel principle in pipes, the amount of water filled is difficult to control, and directly observing the liquid level is challenging. If measurements are taken by inserting the pipe, manual measurement is usually used to ensure cost-effectiveness. However, manual measurement is prone to errors, and it is difficult to operate when the pipe diameter is too small, while posing safety hazards when the pipe diameter is too large. The difficulty of manual measurement is further increased in environments with low liquid levels or poor lighting. Therefore, there are technical problems such as the difficulty in detecting the water level inside the pipe, the difficulty in operation, and the susceptibility to measurement errors.

[0024] Example 1:

[0025] like Figures 1 to 2 The diagram shows an embodiment of a liquid level detection device according to this utility model. It includes a measuring component and a positioning component. The positioning component includes a first positioning element 3 positioned at the measuring position. The measuring component includes a measuring rod 1 and a float 2 connected to the measuring rod 1. The measuring rod 1 and the first positioning element 3 are slidably connected. In this embodiment, the first positioning element 3 and the measuring rod 1 are arranged perpendicularly to each other. The float 2 is made of a material with a density lower than that of the liquid being detected, typically used for water level detection; therefore, the float 2 is usually made of a material with a density lower than water. The measuring rod 1 is made of a waterproof material and is a hollow tube to reduce weight. Using a hollow plastic tube not only meets the usage requirements but also provides light weight and low manufacturing cost. In this embodiment, the float 2 makes the measuring rod 1 float on the liquid surface 91, and the positioning component fixed at the measuring position provides horizontal support for the measuring rod 1. The operator can quickly detect changes in liquid level by observing the relative position of the measuring rod 1 and the positioning component without inserting it into the pipe, ensuring both safety and accuracy. This device is suitable for liquid level detection in various pipelines, and is simple, convenient to install, and has high detection efficiency.

[0026] In this embodiment, the measuring rod 1 is marked with scale lines along its length. During testing, personnel can quickly determine the change in distance between the float 2 and the positioning component by observing the scale changes at the junction of the measuring rod 1 and the positioning component, thus determining the water level change within the pipe 9.

[0027] In this embodiment, the measuring component also includes a top cap 5, which is connected to the measuring rod 1 to prevent slippage. This design better prevents the measuring rod 1 from slipping due to a rapid drop in water level during the water tightness test, ensuring the service life of the measuring rod 1 and preventing the testing tool from falling into the pipe and affecting the internal environment of the pipe. In this embodiment, the top cap 5 and the measuring rod 1 are detachably connected, thus allowing the measuring rod 1 to be detachably connected to the first positioning member 3. This design facilitates the maintenance and repair of the liquid level detection device and also makes it easier to transport and store the device after disassembly.

[0028] In this embodiment, the positioning component is retractable and also includes a second positioning element 4, which is movably connected to the first positioning element 3.

[0029] In different embodiments, the number of the first positioning element 3 and the second positioning element 4 can be designed to include one or more according to the usage requirements. For example, the number of the first positioning element 3 and the second positioning element 4 can both be one and are movably connected to each other to adjust the extension and retraction, with the measuring rod 1 passing through the first positioning element 3; or the number of the first positioning element 3 can still be one, and the number of the second positioning elements 4 can be two, respectively movably connected to both ends of the first positioning element 3, with the measuring rod movably passing through the middle of the first positioning element 3. The first positioning element 3 can be designed in various ways according to the usage requirements, and can be plate-shaped; in this embodiment, the first positioning element 3 is rod-shaped and there are multiple of them. The positioning component also includes a connecting element 6, which can be made of a sleeve. Multiple first positioning elements 3 are connected to each other through the connecting element 6, and each first positioning element 3 is perpendicularly connected to the connecting element 6. The connecting element 6 is slidably connected to the measuring rod 1. In this embodiment, the measuring rod 1 is movably inserted into the connecting element 6. The number of second positioning elements 4 is adapted to the number of first positioning elements 3. In this embodiment, each second positioning element 4 is movably disposed at the end of the corresponding first positioning element 3 away from the connecting element 6. Multiple first positioning elements 3 are evenly distributed around the connector 6. In this embodiment, there are two first positioning elements 3, which are symmetrically arranged on both sides of the connector 6.

[0030] The positioning component also includes multiple clamping rods 7 for securing. Each clamping rod 7 is designed to connect to the first positioning member 3 or the second positioning member 4 in an L-shape, depending on the number and assembly method of the first positioning member 3 and the second positioning member 4. For example, when there is only one first positioning member 3 and one second positioning member 4, and they are movably connected to each other, there can be two clamping rods 7, which are respectively connected to the first positioning member 3 and the second positioning member 4 to form a telescopic inverted U-shaped structure for adjustable securing at the pipe opening. 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 component that can be movably connected to the first positioning member 3.

[0031] In this embodiment, each first positioning member 3 and the second positioning member 4 are movably connected by opening multiple adjustment holes on the second positioning member 4 and opening limiting holes on the first positioning member 3. The positioning component also includes a number of fastening bolt assemblies 8, and the limiting holes correspond to the corresponding adjustment holes and are fixed by the bolt assemblies 8.

[0032] The method of using this utility model includes the following steps:

[0033] During the water tightness test, the measuring rod 1 is inserted through the connector 6 and the top cap 5 is installed. The second positioning component 4 is adjusted to fix the positioning component in the measuring position. During adjustment, the second positioning component 4 can be moved to the appropriate position and fixed by the bolt assembly 8, so that the positioning component is adapted to the size of the pipe 9 and is fixed to the pipe opening by the clamping rod 7. The measuring rod 1 can float on the liquid surface 91 through the float 2. The float 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 of distance between the float 2 and the positioning component can detect the change of water level. In this embodiment, the value can be read directly through the scale line. The tester records the measured value in sequence according to the different time interval requirements to compare the water level changes. This method can improve the detection accuracy and efficiency and is convenient to operate.

[0034] This embodiment can quickly detect water level changes during pipeline water tightness tests without requiring personnel to enter the pipeline, ensuring the safety of the testing process. The retractable and adjustable positioning component can not only reduce space occupation during storage or transportation by retracting, but also adapt to various pipe diameters, ensuring testing stability. It is also widely applicable and can be promoted for widespread use. The structure is simple and easy to operate, ensuring construction testing costs and testing quality, and avoiding errors from manual measurement by different personnel.

[0035] Example 2:

[0036] like Figure 3 As shown, this embodiment also includes an illumination component 10, which is connected to the first positioning component 3. More specifically, compared to embodiment 1, in this embodiment, the illumination component 10 is installed on the connector 6. The illumination component 10 can be made of LED light or fluorescent ring, etc., which is better suited for detection in nighttime or low-light environments. The illumination technology and specific assembly method are existing technologies and will not be described further in this utility model.

[0037] In this embodiment, the top cap 5 may also be provided with a lifting ring 11 to facilitate operation or transportation.

[0038] This embodiment is better suited for complex detection environments such as low light levels, is easy to operate, and can ensure detection accuracy.

[0039] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
