Description

Technical Field

[0001] This utility model relates to the field of steel strip level gauge technology, and in particular to a steel strip level gauge. Background Technology

[0002] The steel strip level gauge is a traditional level gauge. It is designed and manufactured based on the principle of mechanical equilibrium, and consists of a steel strip measuring tape, a displacement transmission system, a display device, a transmitter, and other peripherals. The float, immersed in the measured liquid, is subjected to gravity W, buoyancy F, and a constant pulling force T generated by a constant force device. When the vector sum of these three forces equals zero, the float is in a quasi-equilibrium static state. The buoyancy force at mechanical equilibrium is quasi-constant.

[0003] In existing steel strip level gauges, the steel strips are coated with lubricating oil to reduce friction between the strips. Therefore, when the steel strip level gauge is in use, the lubricating oil adhering to the steel strip can easily fall into the detected liquid, affecting the quality of the detected liquid. Furthermore, when encountering volatile liquids, the volatile liquid solids will also adhere to the steel strip, causing a decrease in the accuracy of the steel strip level gauge in subsequent use. Therefore, it is necessary to design a steel strip level gauge. Utility Model Content

[0004] Therefore, it is necessary to provide a steel strip level gauge to address the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides a steel strip level gauge, including a body in which a steel strip is slidably connected. A first cleaning structure and a second cleaning structure are mounted on the body, arranged symmetrically. Each cleaning structure includes two fixed frames, arranged vertically symmetrically. Several rotating shafts are rotatably mounted within the fixed frames, and these shafts are connected via a transmission assembly. The transmission assembly is equipped with several push blocks for moving sponge blocks. A ratchet is mounted on one of the rotating shafts, and a pawl is mounted on the fixed frame, the pawl engaging with the ratchet.

[0006] Preferably, one of the rotating shafts on the two symmetrically arranged fixed frames is connected by a transmission assembly.

[0007] Preferably, an arc-shaped guide block is installed inside the fixing frame.

[0008] Preferably, a tapered insert is mounted on the push block.

[0009] Preferably, the fixing frame is hinged with a replacement door.

[0010] Preferably, the arc-shaped guide block has a chamfer.

[0011] Preferably, a rotating rod is mounted on one of the rotating shafts of the first cleaning structure and the second cleaning structure.

[0012] Preferably, it also includes a braking structure. Both cleaning structure one and cleaning structure two are equipped with a braking structure. The braking structure includes a slot and a block. The slot is located on one of the rotating shafts. A spring is installed in the slot. A block is slidably engaged in the slot. The output end of the spring is connected to the block. The block and the block are configured to cooperate with each other.

[0013] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0014] 1. By combining cleaning structure one and cleaning structure two, the lubricating oil or solidified detection liquid adhering to the steel strip can be cleaned separately, thereby avoiding affecting the quality of the detection liquid and the accuracy of the steel strip level gauge.

[0015] 2. The rotating shaft is driven by the transmission component to rotate, thereby moving the sponge block attached to the steel belt to one side for replacement. The first cleaning structure and the second cleaning structure rotate in opposite directions, so that the new sponge block can slide from the middle of the cleaned area to the uncleaned area, avoiding incomplete cleaning caused by replacing the sponge block.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 4 This application provides a steel strip level gauge, including a body 1, a steel strip 2 slidably connected inside the body 1, a first cleaning structure and a second cleaning structure installed on the body 1, the first cleaning structure and the second cleaning structure being symmetrically arranged, each of the first cleaning structure and the second cleaning structure including two fixed frames 3, the two fixed frames 3 being symmetrically arranged vertically, a plurality of rotating shafts 4 being rotatably installed inside the fixed frames 3, the plurality of rotating shafts 4 being connected to each other by a transmission assembly 5, the transmission assembly 5 being preferably a chain transmission assembly, the transmission assembly 5 being equipped with a plurality of push blocks 6 for pushing the sponge blocks to move, a ratchet 7 being installed on one of the rotating shafts 4, and a pawl 8 being installed on the fixed frame 3, the pawl 8 being configured to cooperate with the ratchet 7.

[0023] In this embodiment, when the main body 1 detects the liquid level and releases the steel belt 2, the lubricating oil can be cleaned by the sponge block limited by the upper push block 6 of the cleaning structure one. When the detection is completed and the steel belt 2 needs to be retracted, any liquid condensation that may adhere to the steel belt 2 can be cleaned by the sponge block limited by the upper push block 6 of the cleaning structure two. The sponge block has a certain elasticity and is symmetrically arranged vertically with the fixing frame 3, so the entire surface of the steel belt 2 can be cleaned. When the sponge block needs to be replaced, one of the rotating shafts 4 on the fixing frame 3 is driven, thereby driving all the rotating shafts 4 to rotate through the transmission assembly 5, so that the push blocks 6 on the transmission assembly 5 can be driven to move. Thus, the sponge block can be pushed along the inner wall of the fixing frame 3 by the push block 6 to the point of contact with the steel belt 2, and the old sponge block is pushed to the outlet by the previous push block 6 and removed, thereby completing the replacement of the sponge block. The ratchet 7 and pawl 8 are symmetrically arranged in cleaning structure one and cleaning structure two. This allows the ratchet 7 and pawl 8 in cleaning structure one to engage and limit the rotation of the rotating shaft 4 when the main body 1 is releasing the steel belt 2, thus preventing the sponge block in cleaning structure one from rotating. When the main body 1 rewinds the steel belt 2, the ratchet 7 and pawl 8 in cleaning structure two engage and limit the sponge block in cleaning structure two, allowing it to clean any liquid deposits adhering to the steel belt. Due to the symmetrical arrangement of cleaning structure one and cleaning structure two, they can rotate in opposite directions when replacing the sponge block. This allows the old sponge block to move to an uncleaned area before being sent out, while the new sponge block can slide in from an already cleaned area, thereby improving cleaning efficiency.

[0024] In some embodiments, to improve the efficiency of replacing the sponge block, one of the rotating shafts 4 on two symmetrically arranged fixed frames 3 is connected by a transmission assembly 9. The transmission assembly 9 can be a belt drive assembly or a chain drive assembly. Therefore, the transmission of the several rotating shafts 4 on the two fixed frames 3 only requires driving one of the rotating shafts 4, without having to replace the upper and lower fixed frames 3 alternately.

[0025] In some embodiments, to facilitate the pushing of the sponge block to the steel belt 2 by the pusher 6, an arc-shaped guide block 10 is installed inside the fixing frame 3. The top of the fixing frame 3 has rounded corners, which also serve to guide the sponge block, and the arc-shaped guide block 10 guides the sponge block.

[0026] In some embodiments, to prevent the sponge block from falling off, a conical insert 11 is installed on the push block 6. The sponge block pushed by the push block 6 is stopped by the conical insert 11 inserted on it.

[0027] In some embodiments, a replacement door 12 is hinged to the fixing frame 3 for easy replacement of the sponge block. A rubber sealing strip can be installed at the edge of the replacement door 12 to seal the hinge with the fixing frame 3 and prevent dust from entering. A spring should also be installed on the replacement door 12 so that it can close automatically after being opened, preventing staff from forgetting to open it.

[0028] In some embodiments, to facilitate the sponge block sliding onto the arc-shaped guide block 10, the arc-shaped guide block 10 is provided with a chamfer.

[0029] In some embodiments, to facilitate the rotation of the rotating shaft 4, a rotating rod 13 is installed on one of the rotating shafts 4 of the cleaning structure one and the cleaning structure two.

[0030] In some embodiments, to further improve the cleaning effect, a braking structure is also provided. Both cleaning structure one and cleaning structure two are equipped with braking structures. The braking structure includes a slot 14 and a block 15. The slot 14 is located on one of the rotating shafts 4. A spring 16 is installed in the slot 14, and a flat block 17 is slidably engaged within the slot 14. The output end of the spring 16 is connected to the flat block 17. The block 15 and the flat block 17 are configured to cooperate. The braking mechanism ensures that the steel belt 2 can be cleaned by both cleaning structures one and two simultaneously, regardless of whether it is extended or retracted. When braking is not required, the flat block 17 is pulled out, causing it to slide out of the slot 14 within the rotating shaft 4 and disengage from the limit of the block 15. Then, the rotating shaft 4 is rotated to move the sponge block to a position where it is no longer in contact with the steel belt. The flat block 17 is then reset. At this point, since the steel belt 2 is not in contact with the sponge block, it cannot move the sponge block, thus preventing damage to the braking structure or other structures. When the braking structure brakes, due to the presence of the arc-shaped guide plate, even if the sponge block is pulled away from the push block 6, it can be rotated back into the conical insert block 11.

[0031] 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.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
