[0016] Compared with the prior art, the present invention provides an anti-corrosion magnetic flap level gauge, which has the following beneficial effects:

[0017] 1. The anti-corrosion magnetic flap level gauge is provided with a first float and a second float. When liquid enters the liquid level detection component, the liquid will float the first float and the second float, and the first slide groove of the first float will float between the first limit plate and the second limit plate. The first limit plate and the second limit plate are inclined on the side close to the first float and reduce the friction resistance, so that the first float can float normally. At this time, when the second float also floats normally, the second float will move upward, which will cause the magnetic flap on the outside of the detection chamber to flip along the first rotation axis during the movement. The liquid level in the detection chamber can be determined according to the flipped magnetic flap.

[0018] 2. The anti-corrosion magnetic flap level gauge is provided with an inner shell. When the outer shell of the second float is corroded, the protective shell inside the second float is still not corroded. At this time, the overall density of the second float is still less than the density of the liquid and can continue to be used. When the protective shell is corroded, the protective shells between the protective shells can prevent the protective shells around the corroded protective shell from being further corroded. When the protective shells are all corroded and the inner chamber is not corroded, the overall density of the second float is still less than the density of the liquid and can continue to be used, and it can still float to display the liquid level.

[0019] 3. The anti-corrosion magnetic flap level gauge is provided with a float limit plate, and the float limit plate can keep the second float stable during the upward and downward floating of the second float, so that the second float does not flip.

[0020] 4. The anti-corrosion magnetic flap level gauge, by setting the first limit plate and the second limit plate, can keep the first float stable and prevent it from flipping during the upward and downward floating of the first float.

[0021] 5. The anti-corrosion magnetic flap level gauge is provided with a detection pallet. When the liquid in the liquid storage device changes but the magnetic flap of the liquid level detection component does not change, a new first float and a second float can be taken out to detect the magnetic flap. After determining that the magnetic flap is normal, the magnetic pallet can be lifted upward along the detection slide rail. The magnetic pallet and the magnetic block are attracted to each other, and the upward movement of the magnetic pallet will drive the magnetic block to move upward along the first limit groove of the second limit plate. The upward movement of the magnetic block will drive the first connecting rod to move upward. The upward movement of the first connecting rod will drive the detection pallet to move upward. The upward movement of the detection pallet will support the detection block of the first float and thereby drive the first float and the second float to move upward. At this time, if the magnetic flap changes, it can be determined that the first float and the second float have been completely corroded. The detection pallet will drive the first float and the second float to move to the second flange so that the first float and the second float can be taken out and replaced.

[0022] 6. The anti-corrosion magnetic flap level gauge is provided with a first connecting rod, and the upper and lower parts of the first connecting rod are designed as inclined surfaces, which is conducive to reducing the friction resistance between the first connecting rod and the second limit plate when the magnetic support plate drives the magnetic block to move upward. At the same time, it is convenient to discharge the liquid to reduce the friction resistance caused by the liquid to the first connecting rod, which is convenient for the detection and replacement of the first float and the second float.

[0023] 7. The anti-corrosion magnetic flap level gauge is provided with a connecting rod and a first connecting square hole, and the first float and the second float are taken out, and then the second floats on the connecting shells at both ends of the first float are respectively taken out, and the first float is checked whether it can continue to be used, and a new first float is replaced or a new second float is replaced, and the connecting rod on the second float is aligned with one side of the first connecting square hole on the connecting shells at both ends of the first float and inserted, and the second float on the other side of the connecting shell is inverted, and the connecting rod on it is aligned with the other side of the first connecting square hole on the connecting shells at both ends of the first float and inserted. At this time, the connecting rods on the second floats on both sides are respectively connected to each other's second connecting square holes, and the installation is completed. The first float and the second float are placed between them to complete the replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] An inner chamber 218 is provided in the middle part of the second float 208. The inner chamber 218 is a hollow structure and the upper and lower parts are both conical. A protective shell 219 is fixedly installed between the inner chamber 218 and 208. A connecting rod 215 is fixedly installed on the outside of 208. A second connecting square hole 217 is opened on the outside of 208.

[0043] The protective shell 219 is hemispherical and fixedly installed around the inner chamber 218. A protective partition 220 is fixedly installed between the middle position of the protective shell 219 and the inner chamber 218, and the protective partition 220 separates the protective shell 219 from the middle.

[0044] The upper and lower parts of the first connecting rod 305 are both inclined surfaces, and the width of the first connecting rod 305 is equal to the width of the first limiting groove 206 .

[0045] The detection support plate 306 is evenly provided with holes to reduce the resistance of the liquid during detection.

[0046] The proximal end of the magnetic block 304 and the adjacent magnetic support plate 303 are opposite magnetic poles.

[0047] The width of the magnetic support plate 303 is equal to the distance between the two detection slide rails 301 on the same side, and the outer side of the magnetic support plate 303 is arc-shaped.

[0048] When in use, the two second flanges 400 are opened or installed by removing or installing the nuts 402. When the second flanges 400 are opened, the magnetic support plate 303 can be lifted upward along the detection slide rail 301. The magnetic support plate 303 and the magnetic block 304 are attracted to each other. The upward movement of the magnetic support plate 303 will drive the magnetic block 304 to move upward. The upward movement of the magnetic block 304 will drive the first connecting rod 305 to move upward. The upward movement of the first connecting rod 305 will drive the detection support plate 306 to move upward. The upward movement of the detection support plate 306 will support The detection block 209 of the first float 207 drives the first float 207 and the second float 208 to move upward. When they move to the second flange 400, the first float 207 and the second float 208 can be taken out and replaced, which is convenient for replacing the first float 207 and the second float 208. When the second flange 400 is closed, the connecting conduit 100 can be connected to the liquid storage device through the first flange 101. When the valve connecting the liquid storage device and the connecting conduit 100 is opened, the liquid will enter the liquid level detection component 200.

[0049] When liquid enters the liquid level detection component 200, the liquid will make the first float 207 and the second float 208 float, and the first slide groove 210 of the first float 207 will float between the first limit plate 204 and the second limit plate 205. The first limit plate 204 and the second limit plate 205 are inclined on the side close to the first float 207 and reduce the friction resistance, so that the first float 207 can float normally. At this time, when the second float 208 also floats normally, the second float 208 will move upward, which will cause the magnetic flap 202 on the outside of the detection chamber 216 to flip along the first rotating axis 201 during the movement. The liquid level in the detection chamber 216 can be determined according to the flipped magnetic flap 202.

[0050] When the outer shell of the second float 208 is corroded, the protective shell 219 inside the second float 208 is still not corroded. At this time, the overall density of the second float 208 is still less than the liquid density and can continue to be used. When the protective shell 219 is corroded, the 200 between the protective shells 219 can prevent the protective shells 219 around the corroded protective shell 219 from being further corroded. When the protective shells 219 are all corroded and the inner chamber 218 is not corroded, the overall density of the second float 208 is still less than the liquid density and can continue to be used.

[0051] When the liquid in the liquid storage device changes but the magnetic flap 202 of the liquid level detection assembly 200 does not change, a new first float 207 and a second float 208 can be taken out to detect the magnetic flap 202. After confirming that the magnetic flap 202 is normal, the magnetic support plate 303 can be lifted up along the detection slide rail 301. The magnetic support plate 303 and the magnetic block 304 are attracted to each other. The upward movement of the magnetic support plate 303 will drive the magnetic block 304 to move upward along the first limiting groove 206 of the second limiting plate 205. The upward movement of the magnetic block 304 will drive the first connecting rod 206 to move upward. 305 moves upward, the first connecting rod 305 moves upward, which will drive the detection support plate 306 to move upward. The detection support plate 306 moves upward, which will support the detection block 209 of the first float 207, thereby driving the first float 207 and the second float 208 to move upward. At this time, the magnetic flap 202 changes, then it can be determined that the first float 207 and the second float 208 have been completely corroded. The detection support plate 306 drives the first float 207 and the second float 208 to move to the second flange 400, so that the first float 207 and the second float 208 can be taken out and replaced.

[0052] Take out the first float 207 and the second float 208, then remove the second floats 208 on the connecting shells 212 at both ends of the first float 207 respectively, check whether the first float 207 can continue to be used, replace the new first float 207 or replace the new second float 208, align the connecting rod 215 on the second float 208 with one side of the first connecting square hole 214 on the connecting shells 212 at both ends of the first float 207 and insert it, invert the second float 208 on the other side of the connecting shell 212, align the connecting rod 215 on it with the other side of the first connecting square hole 214 on the connecting shells 212 at both ends of the first float 207 and insert it, at this time, the connecting rods 215 on the second floats 208 on both sides are respectively connected to each other's second connecting square holes 217, and the installation is completed. The first float 207 and the second float 208 are placed between 203 to complete the replacement.

[0053] During the upward and downward floating of the second float 208, the float limit plate 203 can keep the second float 208 stable so that it does not flip over. During the upward and downward floating of the first float 207, the first limit plate 204 and the second limit plate 205 can keep the first float 207 stable so that it does not flip over.

[0054] The upper and lower parts of the first connecting rod 305 are designed as inclined surfaces, which is beneficial to reducing the friction resistance between the first connecting rod 305 and the second limit plate 205 when the magnetic support plate 303 drives the magnetic block 304 to move upward. At the same time, it is convenient to discharge the liquid to reduce the friction resistance caused by the liquid to the first connecting rod 305, thereby facilitating the detection and replacement of the first float 207 and the second float 208.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
