Description

A liquid level gauge structure

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 19, 2023, with application number 202311750354.3 and invention name “A Liquid Level Gauge Structure”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of liquid level gauges, and in particular to a liquid level gauge structure. Background Art

[0003] A liquid level gauge is a device used to monitor the level of liquids and is widely used in oil-immersed transformers. Existing level gauges cannot directly monitor the liquid level, are large in size, and have limited application scenarios. With the continuous development of oil-immersed product technology, the demand for smaller level gauges has increased.

[0004] There are two main types of liquid level gauges available. One uses a sensor to convert liquid level information into an electrical signal to display the liquid level, but this type of gauge cannot be used in high-voltage environments. The other uses a transparent material to directly visually check the liquid level. This type of gauge requires a hole to be opened for installation and cannot be used in products that require high structural integrity.

[0005] Existing liquid level gauges are generally integrated into liquid storage cabinets or arranged outside the product. For products without liquid storage cabinets or with high size requirements, how to implement the design of liquid level gauges is a technical problem that needs to be solved urgently by technical personnel in this field.

[0006] Summary of the Invention

[0007] In order to solve the above technical problems, the present invention provides a liquid level gauge structure, which can be integrated on the top of the product, occupies a small space, can be used in high voltage environments, and has good sealing performance.

[0008] The technical solutions provided by the present invention are as follows:

[0009] A liquid level gauge structure includes a float, a liquid level indicator rod and a transparent tube. The float is set in the liquid in the liquid container. One end of the liquid level indicator rod is fixedly connected to the float, and the other end of the liquid level indicator rod extends out of the liquid container through a guide hole on the bottom plate of the liquid container and can move up and down along the guide hole. The transparent tube wraps the liquid level indicator rod extending out of the bottom plate of the liquid container.

[0010] Preferably, a protective cover is further provided on the periphery of the transparent tube, and the protective cover is detachably connected to the bottom plate of the liquid container.

[0011] Preferably, a buffer pad is provided between the outer side surface of the transparent tube and the inner side surface of the protective cover.

[0012] Preferably, an observation hole is provided on the protective cover.

[0014] Preferably, the transparent tube is in an inverted "U"-shaped structure, and the lower end of the transparent tube is directly inserted into the fixing groove on the bottom plate of the liquid container.

[0015] Preferably, a sealing gasket is provided between the outer periphery of the transparent tube and the fixing groove.

[0016] Preferably, a second sealing gasket is provided between the end of the transparent tube and the fixing groove.

[0017] Preferably, the float ball and the liquid level indicator rod are both made of non-conductive materials.

[0018] Preferably, the guide hole is opened at the top of the liquid container.

[0019] This application has the following advantages over the prior art:

[0020] The liquid level gauge structure of the present application can be integrated on the top of the product through the design of the float, liquid level indicator rod and transparent tube, and the float is installed inside the liquid container to save space; in the width direction, the diameter of the liquid level indicator rod is small, and the diameters of the transparent tube and the protective cover are correspondingly small; in the height direction, the height of the liquid level indicator rod, the transparent tube and the protective cover is determined according to the expansion height of the liquid in the container, occupying a small space, can be used in high voltage environments, has good sealing performance, and has a simple structure, making it very convenient to manufacture and use.

The float 1 and the liquid level indicator rod 2 are both made of non-conductive materials and can be used in high-voltage environments. The float 1 is set in the liquid in the liquid container. One end of the liquid level indicator rod 2 is fixedly connected to the float 1. The other end of the liquid level indicator rod 2 extends out of the liquid container through a guide hole 41 on the bottom plate 4 of the liquid container and can move up and down along the guide hole 41. The guide hole 41 is opened at the top of the liquid container and does not destroy the integrity of the product. The transparent tube 3 wraps the liquid level indicator rod 2 extending out of the bottom plate 4 of the liquid container. The transparent tube 3 can be made of glass or plastic. The position of the liquid level indicator rod 2 can be seen through the transparent tube 3. The liquid level gauge structure of this embodiment can be used not only for liquid-immersed transformer level gauges, but also for devices used to display liquid levels in other fields.
