Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, specifically to a magnetic float liquid level gauge that is easy to observe at night. Background Technology

[0002] Magnetic float level gauges (also known as magnetic level gauges) are developed based on the principles of buoyancy and magnetic coupling. When the liquid level in the container being measured rises or falls, the magnetic float in the gauge's main tube also rises or falls accordingly. The permanent magnet inside the float transmits the signal to the magnetic indicator via magnetic coupling, driving the red and white indicator columns to rotate 180 degrees. When the liquid level rises, the indicator column changes from white to red; when the liquid level falls, the indicator column changes from red to white. The red-white boundary of the indicator shows the actual height of the liquid level inside the container, thus providing a clear indication of the liquid level.

[0003] Currently, magnetic level gauges are widely used in the metallurgical industry, especially for measuring the liquid level in pressure vessels. They are characterized by their simple structure, ease of installation, and convenient use. However, the level gauge display can be difficult to observe at night.

[0004] The prior art includes Chinese Patent Publication No. CN207113979U to address the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A light-display type liquid level gauge interlocking control system, belonging to the technical field of magnetic float liquid level gauge equipment. The system comprises a liquid level gauge, LED beads, a magnetic float dial, a magnetic switch, a controller, and an alarm. The liquid level gauge is fixed on the magnetic float dial, which has scales corresponding to the liquid level gauge. Each scale has an LED bead, which is connected to the output module of the controller. One end of the magnetic switch is connected to the input module of the controller, and the other end is connected to the liquid level gauge. The controller is connected to the alarm. The beneficial effect of this invention is that it completely changes the situation where the position of the liquid level gauge is difficult to observe at night, greatly facilitating the control of the liquid level in the container. However, its lighting component is not convenient for controlling the switch according to the actual lighting conditions, which leads to the problem of wasting electricity in well-lit conditions when the magnetic float liquid level gauge is easy to observe at night. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic float level gauge that is easy to observe at night, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A magnetic float level gauge that is easy to observe at night includes:

[0008] The liquid level gauge body has a strong magnetic float inside, which can float up and down in response to changes in the liquid level inside the liquid level gauge body.

[0009] The indicator box is detachably installed on one side of the liquid level gauge body. Inside the indicator box, multiple sets of flap assemblies arranged vertically and horizontally at equal intervals are rotatably installed.

[0010] The indicator box contains multiple sets of lighting components that correspond one-to-one with the flip-plate assembly. The flip-plate assembly has a rotary wheel for controlling the switching of the corresponding lighting component. The indicator box also contains a push-pull assembly for controlling the forward and backward movement of the lighting component.

[0011] Using the above technical solution, the liquid level gauge body and the strong magnetic float are used to follow the changes in the liquid level inside the device to be tested. The up-and-down moving strong magnetic float can be used to control the flip plate assembly to flip and display. Furthermore, there is a light assembly that lights up as the corresponding flip plate assembly flips, which makes it convenient for the magnetic flip plate liquid level gauge to be observed at night. The push-pull assembly controls the displacement of the light assembly, which makes it convenient for the device to decide whether to activate the light assembly according to the actual environment.

[0012] A further improvement of the present invention is that the flip-plate assembly includes a rotating rod rotatably connected to the indicator box, and an indicator flip-plate is fixedly installed between the two sets of rotating rods. One side of the indicator flip-plate is coated with white paint, and the other side is coated with red paint.

[0013] Using the above technical solution, the magnetic indicator flaps coated with different colors on both sides are used in conjunction with a strong magnetic buoy. The strong magnetic buoy can rotate the magnetic indicator flaps that it is close to by moving up and down. The boundary between the different colors of the indicator flaps is the scale for display. The rotating rod is used to provide rotational support for the indicator flaps.

[0014] A further improvement of this utility model is that: the rotating wheel is fixedly installed on both sets of rotating rods by connecting rods, and the front of each set of rotating wheels is provided with a corresponding light component. The outer ring of the rotating wheel is integrally formed with a protruding section for controlling the switching of the light component.

[0015] In the above technical solution, the rotating wheel that follows the rotating rod drives the protruding section to move together, and the protruding section is used to control the switch of its corresponding light component.

[0016] A further improvement of the present invention is that the push-pull assembly includes a vertical plate connecting the same row of light assemblies, and a horizontal plate is fixedly installed between the top and bottom of the two sets of vertical plates. The top and bottom of the inner cavity of the indicator box are provided with a set of driving components for controlling the forward and backward movement of the horizontal plate.

[0017] By adopting the above technical solution, the vertical and horizontal plates in the solution facilitate the assembly of the lighting components into a whole, thereby facilitating the synchronous displacement control of the driven components.

[0018] A further improvement of this utility model is that the driving component includes two sets of round rods and one set of electric telescopic rods fixedly installed inside the indicator box. The two sets of round rods slide through the crossbar, and the output end of the electric telescopic rod is fixedly connected to the center of the crossbar.

[0019] The above technical solution facilitates the displacement of the vertical and horizontal plates by pushing and pulling the electric telescopic rod, and the round rod provides stable auxiliary support for the vertical and horizontal plates.

[0020] A further improvement of this utility model is that a photosensitive sensor is fixedly installed on the indicator box, and the photosensitive sensor is used to detect changes in ambient light to control the operation of the electric telescopic rod.

[0021] The above technical solution incorporates a photosensitive sensor that automatically detects changes in ambient light to control the opening and closing of the electric telescopic pole.

[0022] A further improvement of this utility model is that the lighting assembly includes a lamp ball fixedly installed on the side of the vertical plate away from the rotating wheel, and an automatic reset button for controlling the lamp ball switch is fixedly installed on the side of the vertical plate close to the rotating wheel.

[0023] Using the above technical solution, the automatic reset button can be squeezed by the protruding section. When the automatic reset button is pressed, the corresponding light bulb can be turned on. The automatic reset button can also automatically turn off the light bulb when the protruding section moves away.

[0024] A further improvement of this utility model is that: the front of the indicator box is provided with a transparent window for observing the changes of the flip panel assembly, and both sides of the transparent window are provided with light-transmitting scale windows that correspond one-to-one with the light assembly.

[0025] The above technical solution allows for easy observation of changes in the flip-up assembly inside the indicator box via a transparent window, and facilitates observation of the switching on / off of the corresponding height light bulb and the corresponding display scale via a light-transmitting scale window.

[0026] A further improvement of this utility model is that: multiple sets of equally spaced light-blocking plates are fixedly installed on the front of the vertical plate, and the light-blocking plates are installed between two adjacent sets of light bulbs.

[0027] Using the above technical solution, the light-blocking plate helps reduce the influence of light between adjacent light bulbs, making it easier for staff to accurately observe the corresponding magnetic float level gauge display scale at night.

[0028] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0029] 1. This utility model provides a magnetic float level gauge that is easy to observe at night. It is equipped with a rotating rod and a rotating wheel that can rotate together with the indicator float. The front of the rotating wheel is equipped with a corresponding light component. The rotating wheel is also equipped with a protruding section that can control the switch of the light component. It can control the switch of the light component on both sides while the strong magnetic float drives the indicator float to rotate. This makes it convenient for staff to observe the magnetic float level gauge at night. The rotation of the indicator float and the switching of the light component are synchronized, which can ensure the accuracy of the data observed at night.

[0030] 2. This utility model provides a magnetic float level gauge that is easy to observe at night. It is equipped with a vertical plate and a horizontal plate that combine the lighting components into a whole, and an electric telescopic rod that controls the displacement of the vertical plate and the horizontal plate. The electric telescopic rod is used to control the lighting components to move away from or closer to the rotating wheel. When the ambient light is good, the lighting components move away from the rotating wheel and stop working. This can help reduce unnecessary energy waste of the magnetic float level gauge, thereby improving the environmental friendliness of the magnetic float level gauge. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to embodiments:

[0041] Example 1

[0042] like Figures 1-7 As shown, this utility model provides a magnetic float level gauge that is easy to observe at night, including a level gauge body 1 and a light assembly, etc. The level gauge body 1 is equipped with a strong magnetic float 2 inside, which can float up and down with the changes in the liquid level inside the level gauge body 1. The indicator box 3 is detachably installed on one side of the level gauge body 1. Multiple sets of flip-plate assemblies are rotatably installed inside the indicator box 3. Multiple sets of light assemblies are provided inside the indicator box 3, each corresponding to one of the flip-plate assemblies. The flip-plate assemblies are equipped with a rotating wheel 4 for controlling the switch of the corresponding light assembly. The indicator box 3 is equipped with a push-pull assembly for controlling the forward and backward movement of the light assembly.

[0043] In actual use, the magnetic float level gauge body 1 is assembled to the side of the equipment whose liquid level needs to be detected via a flange connection. The interior of the level gauge body 1 is connected to the liquid inside the equipment. Changes in the liquid level inside the level gauge body 1 can cause the strong magnetic float 2 inside it to float up and down. During the up and down movement of the strong magnetic float 2, it can cause the nearby flip plate assembly to flip. The flip plate assembly drives the rotating wheel 4 to flip, which can also drive the corresponding light assembly to switch on and off. The light assembly at the height corresponding to the strong magnetic float 2 and the light below it are turned on, while the light assembly at the top is turned off. This allows the staff to easily observe the liquid level at night and in other situations. A push-pull assembly is provided to control the distance between the light assembly and the rotating wheel 4. When the light intensity is good, the light assembly is away from the rotating wheel 4. At this time, the rotating wheel 4 will not control the light assembly to turn on, which helps the equipment save power in good lighting conditions.

[0044] like Figures 1-7As shown, in this embodiment, preferably, the flip-plate assembly includes a rotating rod 5 rotatably connected to the indicator box 3. An indicator flip-plate 6 is fixedly installed between the two sets of rotating rods 5. One side of the indicator flip-plate 6 is coated with white paint, and the other side is coated with red paint. The strong magnetic buoy 2 contains a permanent magnet. As the liquid level changes, the strong magnetic buoy 2 moves up and down, driving the magnetic indicator flip-plate 6 in the external indicator box 3 to rotate through magnetic coupling. The boundary between the red magnetic indicator flip-plate 6 and the white magnetic indicator flip-plate 6 can be used as the display height of the magnetic flip-plate level gauge.

[0045] Each of the two sets of rotating rods 5 is fixedly mounted with a rotating wheel 4 via a connecting rod 7. Each set of rotating wheels 4 has a corresponding light component on its front. The outer ring of the rotating wheel 4 is integrally formed with a protruding section 8 for controlling the switching of the light component. When the magnetic indicator flip plate 6 is flipped under the control of the strong magnetic float 2, the rotating rod 5 can drive the rotating wheel 4 to rotate. The protruding section 8 on the outer ring of the rotating wheel 4 rotates to abut against the light component to open it. In addition, two sets of light components are symmetrically arranged on both sides of each set of flip plate components, which can improve the accuracy of the light component's nighttime display.

[0046] Based on the above embodiments, specifically, the push-pull assembly includes vertical plates 9 connecting the same row of light assemblies. Horizontal plates 10 are fixedly installed between the top and bottom ends of the two sets of vertical plates 9. The top and bottom of the inner cavity of the indicator box 3 are each provided with a set of driving components for controlling the forward and backward movement of the horizontal plates 10. In detail, the driving components include two sets of round rods 11 and a set of electric telescopic rods 12 fixedly installed inside the indicator box 3. The two sets of round rods 11 slide through the horizontal rods, and the output end of the electric telescopic rod 12 is fixedly connected to the center of the horizontal plate 10.

[0047] When the upper and lower sets of electric telescopic rods 12 are opened simultaneously, they can drive the horizontal plates 10 connected to them to move. The upper and lower sets of horizontal plates 10 drive the two sets of vertical plates 9 and the connected lighting components to move, which can easily control the lighting components to move closer to or away from the rotating wheel 4. This allows the equipment to adjust the application of the lighting components according to actual needs. Correspondingly, a photosensitive sensor 13 is fixedly installed on the indicator box 3. The photosensitive sensor 13 is used to detect changes in ambient light to control the operation of the electric telescopic rods 12. When the photosensitive sensor 13 detects that the ambient light has dimmed to a certain threshold, it transmits a signal to the controller. The controller controls the opening and closing of the electric telescopic rods 12 through electrical connection, which facilitates the driving convenience of the lighting components. The model of the photosensitive sensor 13 can be selected from existing models, and its signal transmission method is existing technology, which will not be elaborated here.

[0048] The lighting assembly includes a lamp ball 14 fixedly installed on the side of the vertical plate 9 away from the rotating wheel 4. An automatic reset button 15 for controlling the switch of the lamp ball 14 is fixedly installed on the side of the vertical plate 9 close to the rotating wheel 4. When the protruding section 8 of the outer ring of the rotating wheel 4 presses against the automatic reset button 15, pressing the automatic reset button 15 can turn on the lamp ball 14. When the protruding section 8 moves away from the automatic reset button 15, the automatic reset button 15 is automatically reset by the internal spring or other components, and the lamp ball 14 can be automatically turned off. The lamp ball 14 and the automatic reset button 15 can be selected from existing corresponding component models.

[0049] The front of the indicator box 3 is provided with a transparent window 16 for observing changes in the flip-up assembly. On both sides of the transparent window 16, there are light-transmitting scale windows 17 that correspond one-to-one with the lighting assembly, which makes it convenient for operators to observe the corresponding changes in the flip-up assembly and lighting assembly inside the indicator box 3. The light-transmitting scale windows 17 correspond to the corresponding indicator scales, which makes it convenient for staff to observe the corresponding values. Multiple sets of light-blocking plates 18 are fixedly installed on the front of the vertical plate 9. The light-blocking plates 18 are installed between two adjacent sets of light bulbs 14. The light-blocking plates 18 can prevent light interference from the switching of adjacent light bulbs 14 from affecting the observation of actual data.

[0050] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
