[0002] Liquid level gauges are widely used measuring instruments in the fields of chemical industry, petroleum, food, medicine, and environmental protection. Their main function is to measure the liquid level height in various containers such as storage tanks and water tanks.

As a result, it is impossible to quickly judge the safe usage range of the liquid in the container during the personnel inspection, and lighting tools such as flashlights need to be used, which not only increases the operation difficulty but also makes it difficult to take emergency measures in a timely manner when the liquid level is abnormal.

[0019] The technical solution of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0020] A liquid level gauge applicable to a low-light environment in this embodiment refers to the attached Figure 1, including a bracket 1, a measuring cylinder 2, a luminous float 3, a first connecting component and a second connecting component. The measuring cylinder 2 is arranged on the bracket 1, the luminous float 3 is arranged inside the measuring cylinder 2, the first connecting component and the second connecting component are respectively connected to both ends of the measuring cylinder 2, and the first connecting component and the second connecting component are used to communicate with the container to be measured; a luminous indicating scale 4 is arranged on the bracket 1, the luminous indicating scale 4 is located on one side of the measuring cylinder, and both the luminous float 3 and the luminous indicating scale 4 can absorb and store light energy and emit light in a low-light environment.

[0021] In this embodiment, the luminous float 3, the luminous indicating scale 4 and the luminous liquid level marking member 5 are provided. When the light is sufficient, the luminous float 3, the luminous indicating scale 4 and the luminous liquid level marking member 5 absorb and store light energy, and in a low-light environment, the luminous float 3, the luminous indicating scale 4 and the luminous liquid level marking member 5 will slowly release the stored light energy, ensuring that the operator can clearly observe the liquid level position under any lighting conditions, and avoiding the possibility of safety accidents caused by difficult reading of the liquid level height in a low-light environment.

[0022] Preferably, it further includes a luminous liquid level marking member 5, and the luminous liquid level marking member 5 is detachably connected to the other side of the measuring cylinder. By setting a plurality of luminous liquid level marking members 5 to mark key liquid level values such as the normal liquid level fluctuation range and the high and low liquid level warning points, and fixing them on the other side of the measuring cylinder 2, it is convenient for the operator to quickly obtain the safe range of the liquid level and timely identify abnormal liquid levels. In a low-light environment, the luminous liquid level marking member 5 emits light together with the luminous float 3 and the luminous indicating scale 4, facilitating the operator's observation. Through the detachable connection between the luminous liquid level marking member 5 and the bracket 1, for containers with different capacities or different liquid level safety requirements, it is convenient to replace or adjust the position and quantity of the marking members, with wide versatility.

[0023] Further, a fixed card slot 6 is formed on the bracket 1, the fixed card slot 6 is located on the other side of the measuring cylinder, a buckle is provided on the back of the luminous liquid level marking member 5, and the luminous liquid level marking member 5 is detachably connected to the bracket 1 through the cooperation of the buckle and the fixed card slot 6. Through the cooperation of the fixed card slot 6 and the buckle, the luminous liquid level marking member 5 can be fixed on the other side of the measuring cylinder 2. This connection method is relatively firm and is not easily detached under vibration or external force. When the operator needs to disassemble or replace the marking member, the operator only needs to insert and pull out the luminous liquid level marking member 5 to achieve it, without using additional tools.

[0024] Preferably, the luminous float 3 is made of a light and corrosion-resistant material. The luminous float 3 made of a light and corrosion-resistant material can float up and down with the liquid level inside the measuring cylinder 2, ensuring the accuracy of liquid level detection, and ensuring that the luminous float 3 can work stably in the liquid for a long time, reducing the maintenance cost and meeting the detection requirements for various liquids.

[0025] Preferably, the luminous float 3 is filled with a luminous filler. By filling the luminous float 3 with a luminous filler made of a luminous material, the luminous brightness and duration of the luminous float 3 can be significantly increased, ensuring that in low-light environments, operators can easily observe the position of the float and thus accurately read the liquid level data. Utilizing the self-luminous property of the luminous material not only reduces the dependence on lighting equipment but also enables it to emit light without continuous power supply, reducing energy consumption and costs.

[0026] Preferably, the surface of the luminous float 3 is coated with a first luminous coating. Thus, the first luminous coating is directly attached to the surface of the float, ensuring that in low-light environments, operators can easily observe the position of the float and the liquid level situation. In addition, coating the first luminous coating does not significantly increase the weight of the float, so the lightweight property of the float can be maintained, ensuring good buoyancy and measurement accuracy.

[0027] Preferably, the surface of the luminous liquid level marking member 5 is coated with a second luminous coating. Thus, the second luminous coating enables the liquid level marking member to emit light by itself in low-light environments, allowing operators to more easily obtain key information such as the liquid level safety range and high and low liquid level alarm points to quickly determine whether the current liquid level is within the safe range.

[0028] Preferably, the surface of the luminous indicating scale 4 is coated with a third luminous coating. The third luminous coating enables the luminous indicating scale 4 to emit light by itself in low-light environments, facilitating operators to accurately align the float with the scale and reducing measurement errors caused by insufficient light or unclear scales, which ensures the accuracy and reliability of liquid level measurement. The first luminous coating, the second luminous coating, and the third luminous coating are all made of luminous materials, and the luminous materials can be selected from fluorescent powders and luminous pigments.

[0029] Preferably, the first connection assembly includes a first connection flange 71 and an air inlet valve 72. The first connection flange 71 is connected to an interface of the air inlet valve 72, and the other interface of the air inlet valve 72 is connected to one end of the measuring cylinder 2. By providing the first connection flange 71, it is used to connect to the top of the container to be measured; by providing the air inlet valve 72, it is used to control the on-off of the air intake between the measuring cylinder 2 and the container to be measured.

[0030] Preferably, the second connection assembly includes a second connection flange 81, a liquid inlet valve 82, and a drain valve 83. The first interface of the liquid inlet valve 82 is connected to the second connection flange 81, the second interface of the liquid inlet valve 82 is connected to the drain valve 83, and the third interface of the liquid inlet valve 82 is connected to the other end of the measuring cylinder 2. By providing the second connection flange 81, it is used to connect to the bottom of the container to be measured; by providing the liquid inlet valve 82, it is used to control the on-off of the liquid intake between the measuring cylinder 2 and the container to be measured.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
