Abstract
Description
Technical Field
[0001] This utility model belongs to the field of liquid level gauge technology, specifically relating to a hydrogen peroxide storage tank liquid level gauge. Background Technology
[0002] Hydrogen peroxide storage tanks are used to store hydrogen peroxide for later use. In order to accurately measure the liquid level of hydrogen peroxide in the storage tank, a level gauge is needed.
[0003] According to patent number CN202421992470.6, a hydrogen peroxide storage tank level gauge includes a level gauge body, a protective shell is installed on the outside of the level gauge body, and multiple U-shaped viewing windows are provided on the outside of the protective shell; connectors are installed on both ends of the protective shell.
[0004] The above solution still has certain technical defects in actual use. Since the tank of the level gauge is wrapped by a protective shell, the observation effect is not good as it can only be observed through the U-shaped viewing window. Moreover, at night or in poor lighting conditions, it will seriously affect the structure of observation and reading. Therefore, we propose a hydrogen peroxide storage tank level gauge. Utility Model Content
[0005] The purpose of this invention is to provide a hydrogen peroxide storage tank level gauge to solve the existing problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen peroxide storage tank level gauge, comprising a level gauge body, an extension tube, and a light box. The extension tube is fixedly and sealed to the top of the level gauge body. A hollow rod extending into the tube body of the level gauge body is slidably disposed inside the extension tube. A float ball is disposed at the bottom of the hollow rod and is placed inside the tube body of the level gauge body. A top plate is fixedly installed on the top of the hollow rod. A conductive ring is fixedly installed at the middle of the outer periphery of the top plate. Positive and negative electrode plates are equidistantly embedded on the inner walls of both sides of the extension tube. A light box is fixedly installed on the outside of the extension tube. Colored lights of different colors are equidistantly arranged from top to bottom on one side of the light box.
[0007] Preferably, the positive and negative terminals of the colored light are electrically connected to the positive and negative terminals at the same height via wires.
[0008] Preferably, a connecting pipe is provided on the same side of the top and bottom of the liquid level gauge body, and the connecting pipe is connected to both ends of the tube body of the liquid level gauge body.
[0009] Preferably, a flange is provided at the end of the connecting pipe, and the connecting pipe is sealed to the connecting pipe of the storage tank through the flange.
[0010] Preferably, a control valve is provided at the end of the connecting pipe away from the flange, and the valve body of the control valve extends to the connection point between the level gauge body and the connecting pipe.
[0011] Preferably, the tube of the liquid level gauge body is made of transparent material, and scale lines are engraved on the outside of the tube of the liquid level gauge body.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. By setting an extension tube at the top of the tube body of the level gauge, and transmitting the distance that the float moves upward due to being pushed by the liquid to the top plate through the hollow rod, the conductive ring on the outer periphery of the top plate can contact the positive and negative electrode plates at the corresponding heights. This allows the colored light to form a path with the external power supply and emit a light source of the corresponding color, so that the staff can judge the liquid level in the storage tank by the color of the colored light at night or in low light.
[0014] 2. By using a hollow rod to connect the float to the top plate, the influence of the weight of the top plate and the hollow rod on the float is reduced, thus preventing the float from sinking and causing the height of the conductive ring to deviate, thereby reducing the measurement accuracy of the level gauge.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3This utility model provides a technical solution for a hydrogen peroxide storage tank level gauge: it includes a level gauge body 1, an extension tube 5, and a light box 12. The extension tube 5 is fixedly and sealed to the top of the level gauge body 1. A hollow rod 6 extending into the tube body of the level gauge body 1 is slidably arranged inside the extension tube 5. A float ball 7 is arranged at the bottom of the hollow rod 6 and is placed inside the tube body of the level gauge body 1. A top plate 8 is fixedly installed on the top of the hollow rod 6. A conductive ring 9 is fixedly installed at the middle of the outer periphery of the top plate 8. Positive electrode plates 10 and negative electrode plates 11 are equidistantly embedded on the inner walls of both sides of the extension tube 5. A light box 12 is fixedly installed on the outside of the extension tube 5. Colored lights 13 of different colors are equidistantly arranged from top to bottom on one side of the light box 12. The positive electrode of the colored light 13 is connected to the positive electrode plate 10 through an external power supply.
[0021] Specifically, the positive and negative terminals of the colored light 13 are electrically connected to the positive terminal 10 and the negative terminal 11 at the same height via wires.
[0022] Specifically, a connecting pipe 2 is provided on the same side of the top and bottom of the liquid level gauge body 1, and the connecting pipe 2 is connected to both ends of the tube body of the liquid level gauge body 1.
[0023] Specifically, a flange 3 is provided at the end of the connecting pipe 2, and the connecting pipe 2 is sealed to the connecting pipe of the storage tank through the flange 3.
[0024] Specifically, a control valve 4 is provided at the end of the connecting pipe 2 away from the flange 3, and the valve body of the control valve 4 extends to the connection point between the level gauge body 1 and the connecting pipe 2.
[0025] Specifically, the tube of the level gauge body 1 is made of transparent material, and scale lines 14 are engraved on the outside of the tube of the level gauge body 1.
[0026] In this embodiment, during use, the connecting pipe 2 between the top and bottom of the upper tube of the level gauge body 1 is connected to the connecting pipe of the storage tank via the flange 3, ensuring a sealed connection. Then, by opening the control valve 4, the liquid in the storage tank flows into the tube of the level gauge body 1 through the connecting pipe 2, pushing the float 7 upward. This causes the float 7 to drive the hollow rod 6 to extend into the extension tube 5, and the hollow rod 6 pushes the top plate 8 upward, causing the conductive ring 9 on the outer periphery of the top plate 8 to contact the interior of the extension tube 5. The positive electrode 10 and negative electrode 11 at corresponding heights on both sides of the inner wall are in contact, so that the positive and negative electrodes of the colored lights 13 inside the light box 12, which are at the same height as the top plate 8, are connected through the positive electrode 10, negative electrode 11 and conductive ring 9. This allows the colored lights 13 to form a path with the external power source, thereby supplying power to the colored lights 13 and making them emit light stably. This allows the staff to judge the liquid level height based on the color of the colored lights 13. This design effectively solves the problem of not being able to observe the liquid level scale at night or in low light.
