Description

Technical Field

[0001] This invention belongs to the field of liquid level gauge technology, and particularly relates to a high-precision intelligent liquid level gauge. Background Technology

[0002] A water level gauge, also called a "liquid level gauge" or "liquid level gauge," is used in boilers. Because water in a boiler vaporizes at high temperatures for heating, significant water and steam losses occur, requiring continuous water replenishment to maintain a certain water level. If the water level is too low, the boiler risks explosion. To monitor the water level in the boiler at any time, a water level gauge is installed, forming a communicating vessel with the boiler. Commonly used types include glass water level gauges, pressure water level gauges, float water level gauges, capacitive water level gauges, and resistance water level gauges. Isotope water level gauges can also be used under high temperature and high pressure conditions.

[0003] Some current level gauges can only detect a single device, which makes them incompatible and increases costs. Summary of the Invention

[0030] like Figure 1-10 As shown, a high-precision intelligent liquid level gauge includes a storage chamber 1. The storage chamber 1 is equipped with an installation box 2, the installation box 2 is equipped with a floating device 3, the installation box 2 is equipped with a limiting device 4 to restrict the resetting of the floating device 3, the installation box 2 is equipped with a transmission device 5, the floating device 3 drives the transmission device 5, a part of the liquid level gauge 6 is located inside the storage chamber 1, and the transmission device 5 changes the receiving area of ​​the liquid level gauge 6.

[0031] Other devices are installed in the mounting box 2 and the mounting box 2 is placed inside the storage chamber. The floating device 3 converts the distance according to the density of the detected liquid. The floating device 3 drives the transmission device 5 to rotate. At the same time, the limiting device 4 restricts the floating device 3 from resetting, causing the transmission device 5 to reset and rotate. The rotation of the transmission device 5 causes the receiving area of ​​the liquid level gauge 6 to change, thereby moving the liquid level to the liquid within a certain density range.

[0032] Among them, such as Figure 1-10 As shown, the floating device 3 includes a float 3-1, a sliding bar 3-2, a push ring 3-3, a first spring 3-4, and a toothed surface 3-5. The sliding bar 3-2 slides on the storage chamber 1. The float 3-1 is mounted on the sliding bar 3-2. The first spring 3-4 is fitted onto the sliding bar 3-2 and is placed between the mounting box 2 and the push ring 3-3. The toothed surface 3-5 is mounted on the sliding bar 3-2. The sliding bar 3-2 drives the transmission device 5 through the toothed surface 3-5. The limiting device 4 restricts the sliding bar 3-2 from resetting.

[0033] When the mounting box 2 is submerged in the liquid, the float 3-1 will experience buoyancy. The higher the density of the liquid, the greater the buoyancy. The float 3-1 will then move the sliding bar 3-2. The sliding bar 3-2 drives the transmission device 5 to rotate via the toothed surface 3-5, simultaneously compressing the first spring 3-4. The limiting device 4 will also prevent the sliding bar 3-2 from returning to its original position.

[0034] Among them, such as Figure 1-10As shown, the limiting device 4 includes a mounting cylinder 4-1, a sliding cavity 4-2, a sliding plug 4-3, a connecting post 4-4, a second spring 4-5, a third spring 4-6, a sliding plug plate 4-7, an inclined post 4-8, and an inclined groove 4-9. The mounting cylinder 4-1 is disposed inside the mounting box 2, the sliding cavity 4-2 is disposed inside the mounting cylinder 4-1, the sliding plug 4-3 slides inside the sliding cavity 4-2, the connecting post 4-4 is disposed on the sliding plug 4-3, the third spring 4-6 is disposed inside the connecting post 4-4, the sliding plug plate 4-7 slides inside the connecting post 4-4, the third spring 4-6 is positioned between the connecting post 4-4 and the sliding plug plate 4-7, the inclined post 4-8 is disposed on the sliding plug plate 4-7, and the inclined groove 4-9 is disposed on the moving slide bar 3-2. The inclined post 4-8 and the inclined groove 4-9 cooperate to limit the reset of the moving slide bar 3-2.

[0035] The compression of the liquid pushes the sliding plug 4-3 to move in the sliding cavity 4-2. The sliding plug 4-3 drives the connecting column 4-4 to move. The connecting column 4-4 drives the third spring 4-6, the sliding plug plate 4-7, the inclined column 4-8, and the inclined groove 4-9 to move together. When the moving slider 3-2 moves downward, the inclined groove 4-9 will disengage from the inclined column 4-8. When the inclined column 4-8 and the inclined groove 4-9 cooperate to restrict the return of the moving slider 3-2, the third spring 4-6, the sliding plug plate 4-7, and the inclined column 4-8 allow the inclined column 4-8 to have room to move.

[0036] Among them, such as Figure 1-10 As shown, the limiting device 4 also includes a drain port 4-10, which is disposed on the mounting cylinder 4-1. The mounting cylinder 4-1 and the sliding cavity 4-2 are connected.

[0037] The drain port 4-10 facilitates the discharge of liquid inside the installation cylinder 4-1.

[0038] Among them, such as Figure 1-10 As shown, the transmission device 5 includes a rotating shaft 5-1, a first gear 5-2, a second gear 5-3, a movable rack 5-4, and a movable connecting bar 5-5. The rotating shaft 5-1 is rotatably disposed inside the mounting box 2. The first gear 5-2 and the second gear 5-3 are disposed on the rotating shaft 5-1. The movable connecting bar 5-5 slides on the mounting box 2. The movable rack 5-4 is disposed on the movable connecting bar 5-5. The movable rack 5-4 meshes with the second gear 5-3. The first gear 5-2 meshes with the tooth surface 3-5.

[0039] The movable slider 3-2 drives the first gear 5-2 to rotate via the tooth surface 3-5. The first gear 5-2 drives the second gear 5-3 to rotate via the rotating shaft 5-1. The rotating second gear 5-3 drives the movable rack 5-4 to move. The movable rack 5-4 drives the movable connecting bar 5-5 to move.

[0040] Among them, such as Figure 1-10 As shown, there is one second gear 5-3 and one movable rack 5-4.

[0041] Among them, such as Figure 1-10 As shown, the level gauge 6 includes a fixed frame 6-1, a movable baffle 6-2, an expansion device 6-3, a transmission cavity 6-4, a connecting pipe 6-5, a movable plug 6-6, and a marking cavity 6-7. The fixed frame 6-1 is located inside the storage chamber 1. The movable baffle 6-2 slides inside the fixed frame 6-1. The expansion device 6-3 is located inside the fixed frame 6-1. The movement of the movable baffle 6-2 changes the area of ​​the expansion device 6-3. The connecting pipe 6-5 is located on the fixed frame 6-1. The space enclosed by the expansion device 6-3, the fixed frame 6-1, and the movable baffle 6-2 is the transmission cavity 6-4. The connecting pipe 6-5 is connected to the transmission cavity 6-4. The movable plug 6-6 slides inside the connecting pipe 6-5. The upper end of the movable plug 6-6 is the marking cavity 6-7. The movable connecting bar 5-5 drives the movable baffle 6-2 to move.

[0042] The moving connecting bar 5-5 drives the moving baffle 6-2 to move. The moving baffle 6-2 causes the area of ​​the expansion device 6-3 to change. The changed expansion device 6-3 alters the ratio between the expansion device 6-3 and the moving plug 6-6, thereby changing the force ratio at both ends.

[0043] Among them, such as Figure 1-10 As shown, the expansion device 6-3 includes a fixed plate 6-3-1, a first sliding groove 6-3-2, a first moving block 6-3-3, an area expansion plate 6-3-4, a second sliding block 6-3-5, and a second sliding groove 6-3-6. The fixed plate 6-3-1 is disposed inside the fixed frame 6-1. The fixed plate 6-3-1 is provided with the first sliding groove 6-3-2. The first moving block 6-3-3 slides inside the first sliding groove 6-3-2. The area expansion plate 6-3-4 is disposed on the first moving block 6-3-3. The second sliding block 6-3-5 is disposed on the area expansion plate 6-3-4. The second sliding block 6-3-5 slides on the moving baffle 6-2 through the second sliding groove 6-3-6.

[0044] The moving baffle 6-2 drives the area expansion plate 6-3-4 to move, and the area formed by the area expansion plate 6-3-4 and the first moving block 6-3-3 increases.
