Description

Technical Field

[0001] This utility model relates to a liquid level detection device, belonging to the technical field of liquid level detection equipment. Background Technology

[0002] Existing continuous electroplating chemical tanks are all fully enclosed, making it difficult to accurately observe the chemical levels within the tank, causing significant challenges for engineers and chemical analysts. To address this issue, current technologies often employ level float devices or transparent plates welded into the chemical tank to monitor the chemical levels.

[0003] However, while using a transparent plate sandwiched between the chemical tank and the plating tank allows observation of the chemical level within the tank, the welded joints are prone to instability, leading to chemical leakage. Furthermore, chemical residue can easily adhere to the tank walls, leaving marks that can be confused with level markings and cause misjudgments. Liquid level float devices, on the other hand, can only monitor a limited range of level changes and mostly rely on scale lines to determine the level. However, chemical tanks are generally large or installed below electroplating equipment, making it difficult for workers to observe or read the scale readings from a distance, hindering rapid level determination. Utility Model Content

[0004] This utility model provides a liquid level detection device, which solves the problems of existing medicine tanks where the welded transparent plate is prone to weak welding, leading to medicine leakage, and the tank wall is prone to medicine adhesion, resulting in adhesion marks that are confused with liquid level marks and cause misjudgment. It also solves the problem that liquid level float devices are not conducive to workers observing or reading scale readings from a distance, making it impossible to quickly determine the liquid level height.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a liquid level detection device, including

[0007] Floating rod;

[0008] A buoy, with one end of the buoy rod connected to the buoy;

[0009] A liquid level indicator is installed on one side of the float.

[0010] Colored paper is affixed to the side of the liquid level indicator plate near the float.

[0011] In one embodiment of this invention, a liquid level cylinder is included, which is sleeved around the outer periphery of the float and the float rod. This reduces the corrosion of the liquid level detection device by the chemical solution and extends the service life of the device.

[0012] In one embodiment of this utility model, a mounting base is included, which is sleeved on the outer periphery of the float, and the liquid level cylinder is connected to the mounting base.

[0013] In one embodiment of this invention, a locking ring is included, which is sleeved on the outer periphery of the float and can abut against the mounting base. This prevents the float from continuously descending and falling into the medicine tank.

[0014] In one embodiment of this utility model, the width of each color of the colored paper is a fixed value, and the width of the colored paper is adapted according to requirements. Different widths represent different scale values. When observing, engineers or chemical analysts can quickly determine the height of the liquid level in the chemical tank by observing the position of the top of the float corresponding to the colored paper. The liquid level in the tank can be obtained without close observation. The structure is simple and suitable for installation environments that are complex and where it is not convenient for staff to get close to observe and read the scale readings.

[0015] In one embodiment of this utility model, a first bracket is installed at the end of the mounting base away from the liquid level cylinder.

[0016] In one embodiment of this utility model, a second bracket is included, which is connected to the mounting base, and the liquid level indicator is mounted on the second bracket.

[0017] In one embodiment of this invention, the second bracket is provided with a strip-shaped hole. The position of the liquid level indicator plate can be adjusted by adjusting the position of the bolt in the strip-shaped hole.

[0018] In one embodiment of this utility model, a top plate is included, which is connected to the first support and the second support. The top plate can limit the height of the float, preventing the float from rising too high and affecting the operation of other components in the electroplating equipment.

[0019] In one embodiment of this invention, the float has a hollow interior. This reduces the weight of the float and the buoy, resulting in more accurate detection data and a more sensitive response.

[0020] Beneficial effects

[0021] This utility model provides a liquid level detection device comprising a float, a buoy, and a liquid level indicator plate. The indicator plate is covered with colored paper, each color having a fixed width. Engineers or chemical analysts can quickly determine the liquid level in the chemical tank by observing the position of the top of the float corresponding to the colored paper, without needing to approach the tank for close observation. This allows for real-time monitoring of the liquid level. The device has a simple structure, avoiding the leakage problems associated with welded transparent plates and the difficulty of remote observation and reading scale readings with traditional float-type devices. Furthermore, the lightweight buoy and float result in more accurate and sensitive detection data. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] like Figures 1 to 4 As shown, this application provides a liquid level detection device that assists engineers and chemical analysts in quickly observing the liquid level inside an electroplating chemical tank. The liquid level detection device includes a float 4, a mounting base 5, a second bracket 3, a liquid level indicator plate 8, and a float 9. The liquid level detection device is mounted on the cover plate of the electroplating chemical tank via the mounting base 5. The mounting base 5 has a through hole through which the float 4 passes. One end of the float 4 is connected to the float 9. A liquid level cylinder 7 is mounted on one end of the mounting base 5. The liquid level cylinder 7 has a cylindrical structure, and the float 9 is installed inside the liquid level cylinder 7 and slidably connected to it, allowing it to move up and down along the liquid level cylinder 7. The liquid level cylinder 7 is fitted over the float 9 and float 4, reducing the corrosion of the liquid level detection device by the chemicals and extending its service life. The float 9 also has a hollow internal structure, reducing the weight of the float 9 and float 4, resulting in more accurate detection data and a more sensitive response.

[0032] In some embodiments, a locking ring 6 is installed on the side of the float 4 away from the float cylinder 9. The locking ring 6 is sleeved on the outer periphery of the float 4 and has a threaded hole. A bolt is screwed into the threaded hole, and the bottom of the bolt abuts against the float 4, so that the locking ring 6 is fixedly connected to the float 4. The locking ring 6 can also abut against the mounting base 5 to prevent the float 4 from continuously descending and falling into the chemical tank. A first bracket 2 and a second bracket 3 are installed on the end of the mounting base 5 away from the liquid level cylinder 7. A top plate 1 is connected to the end of the first bracket 2 and the second bracket 3 away from the mounting base 5. The top plate 1 can limit the height of the float 4 to prevent the float 4 from rising too high and affecting the operation of other components in the electroplating equipment.

[0033] In some embodiments, a strip-shaped hole 31 is provided on the second bracket 3, and a liquid level indicator plate 8 is installed on the second bracket 3. A bolt passes through the strip-shaped hole 31 to connect the liquid level indicator plate 8 to the second bracket 3. The position of the liquid level indicator plate 8 can be adjusted by adjusting the position of the bolt in the strip-shaped hole 31. Colored paper 10 is pasted on the liquid level indicator plate 8. The colored paper 10 is composed of a variety of different colors, which are arranged in sequence. The width of each color of the colored paper 10 is set to a fixed value. Different widths represent different graduation values. When observing, engineers or chemical analysts can quickly determine the height of the liquid level in the chemical tank by observing the position of the top of the float 4 corresponding to the colored paper 10. The liquid level in the tank can be obtained without close observation. The structure is simple and suitable for installation environments that are complex and where it is not convenient for staff to get close to observe and read the scale readings.

[0034] Specifically, in this embodiment, the colored paper 10 uses three different colors of photo paper: red, yellow, and blue. These colors are pasted onto the liquid level indicator plate 8 in sequence. The red, yellow, and blue colors are relatively eye-catching, making it easy for staff to quickly determine the height of the liquid level in the medicine tank.

[0035] The working principle of this invention is as follows: The liquid level detection device is installed on the electroplating chemical tank via the mounting base 5. The liquid level cylinder 7 is immersed in the chemical tank, and the chemical solution enters the interior of the liquid level cylinder 7 through a hole at the bottom. The float 9 floats above the chemical solution and moves up and down within the liquid level cylinder 7 according to the liquid level in the tank. Workers can monitor the liquid level in the chemical tank in real time by observing the position of the top of the float 4 and the corresponding colored paper on the liquid level indicator plate 8. This liquid level detection device has a simple structure and can be directly installed on the electroplating chemical tank via the mounting base 5, facilitating movement and maintenance. By observing the position of the top of the float 4 and the corresponding colored paper on the liquid level indicator plate 8, the liquid level in the chemical tank can be monitored in real time, allowing workers to observe from a distance and quickly determine the liquid level in the chemical tank. Furthermore, it eliminates the need for welding a transparent plate, solving the problem of chemical leakage.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
