Description

Technical Field

[0001] The present invention relates to the technical field of automatic water replenishment devices, and in particular to an automatic water replenishment device for a water seal well based on liquid level monitoring and an automatic water replenishment system. Background Art

[0002] In order to ensure the safe operation of the oilfield station, water seal wells were set up at the drainage outlet of the fire embankment in the oil tank area, the total rainwater drainage outlet of the station, the water inlet of the emergency pool, etc. in accordance with the specifications during the design. Since the above drainage systems are used less frequently, especially the drainage system to the accident emergency pool is only used in an accident state, the water seal wells are usually dry and cannot play a role in fire prevention. As long as one of them catches fire, it may spread along the pipeline system and ignite the oil residues and flammable gases in the pipeline, posing a serious safety hazard.

[0003] Chinese patent number CN204570877U discloses an automatic water-replenishing water seal well, including a water seal well, a water seal well replenishing water tank fixedly installed on one side of the inner wall of the water seal well, a water replenishing pipeline connected to the water supply network outside the water seal well is arranged on the upper part of the water seal well replenishing water tank, a connecting pipe is arranged at the lower part of the water seal well replenishing water tank to communicate with the water seal well, a float valve is connected to the water replenishing pipeline inside the water seal well replenishing water tank, a water inlet valve is installed on the water replenishing pipeline outside the water seal well replenishing water tank, and a water outlet check valve is arranged on the connecting pipe. The utility model has a simple structure and low cost, realizes automatic water replenishment of the water seal well, enables the water seal well to achieve a water seal effect, and reduces the risk of safety accidents in oilfield stations and warehouses.

[0004] The existing technical solution mainly uses the float to directly drop under the action of gravity, the piston opens, and water flows out from the water supply pipeline to replenish the water in the well; the water level in the water seal well rises due to the water replenishment, and the float also rises under the action of buoyancy. When the water surface is flush with the bottom of the water outlet pipe of the water seal well, the piston just closes the water supply pipeline.

[0005] The existing technology using a float to control the liquid level cannot accurately control it, because after long-term use, the float surface will absorb more impurities or rust, causing the quality of the float to change, thereby causing the liquid level controlled by the float to change. At the same time, the valve assembly is composed of a float, a connecting rod and a piston switch. If one of the parts is damaged, it will affect the normal water replenishment process. If the liquid level is detected by an existing sensor, the detection end of the sensor may also be affected by the water quality, and stains will condense on the sensor surface to affect the detection.

[0016] An automatic water replenishment system of an automatic water replenishment device for a water seal well based on liquid level monitoring comprises the following steps;

[0017] S1. The monitoring end of the induction water replenishment device continuously monitors the water level changes inside the liquid level measuring tube. The water level changes are captured in real time and converted into electrical signals. The system analyzes the electrical signals to obtain the current water level value.

[0018] S2. Compare the current water level with the preset safe water level range. If the water level is lower than the lower limit of the safe water level, it is determined that water replenishment is required.

[0019] S3. If the float water supply valve functions normally, water flows into the water seal well through the water supply pipe and the rotating drainage pipe. The self-cleaning float floats with the rise and fall of the water level. The buoyancy interval mechanism ensures its floating stability and avoids excessive and frequent water supply operations.

[0020] S4. During the water replenishment process, the rotating drainage pipe rotates, driving the cleaning mechanism to rotate synchronously to clean the inside of the liquid level measuring tube and the conical filter layer. At the same time, the rotation of the rotating drainage pipe also drives the self-cleaning float to rotate, realizing the self-cleaning of the surface of the self-cleaning float;

[0021] S5. When the water level reaches the upper limit of the safe water level, the float water supply valve is closed and the water supply stops. The system continues to monitor the water level to ensure that the water level remains within the safe range.

[0022] S6. If the float water supply valve is damaged due to long-term use or other reasons, the monitoring end of the induction water supply device will automatically trigger the backup water supply mode after detecting that the water level continues to drop, that is, directly control the water supply pipe to open for water supply.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The device achieves precise control of the liquid level in the water seal well by integrating the inductive water replenishment device and the self-cleaning float. The monitoring end of the inductive water replenishment device can capture the water level changes in real time, while the self-cleaning float floats stably through the buoyancy interval mechanism. At the same time, the rotating drainage pipe rotates during the water replenishment process, driving the cleaning mechanism and the self-cleaning float to rotate synchronously. When the cleaning mechanism rotates, it cleans the inside of the liquid level measuring tube and the conical filter layer, effectively preventing the accumulation of impurities from affecting the measurement accuracy, and ensuring the accuracy and reliability of the water replenishment operation. The self-cleaning float has a self-cleaning function when it rotates to avoid the level control error caused by impurities on the surface of the self-cleaning float.

[0025] 2. The device adopts a dual water replenishment mechanism of an induction water replenishment device and a float water replenishment valve. When the float water replenishment valve is damaged due to long-term use, the induction water replenishment device can automatically open the water replenishment pipeline to ensure the continuity and stability of water replenishment. This redundant design effectively avoids water replenishment failure caused by failure of a single component and improves the reliability and safety of the device. When the water level of the water seal well drops, the device can replenish water in time to ensure the normal operation of the water seal well.

[0026] 3. The device integrates multiple functions such as liquid level measurement, automatic water replenishment, self-cleaning and redundant monitoring, realizing the integration and intelligence of functions. Through the design of the self-cleaning mechanism, the service life of the device is effectively extended, and the measurement error and water replenishment failure caused by impurity accumulation are reduced. At the same time, the device has a compact structure and is easy to install. It is suitable for various water seal well environments and provides an efficient and stable solution for the liquid level control and water replenishment operation of the water seal well.

DETAILED DESCRIPTION

[0039] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] See also Figures 1 to 10 As shown, a water seal well based on liquid level monitoring includes a stable water replenishment device installed inside the water seal well 1, and the stable water replenishment device includes a liquid level measuring tube 2, a water replenishment pipeline 3, an induction water replenishment device 5, a float water replenishment valve 4, and a pipeline positioning frame 6; the pipeline positioning frame 6 is installed inside the water seal well 1; the liquid level measuring tube 2 is vertically installed on the pipeline positioning frame 6, and a conical filter layer 21 is provided at the bottom of the liquid level measuring tube 2; the water replenishment pipeline 3 is installed on the top of the liquid level measuring tube 2, and a rotating drainage pipeline 3 is also installed on the water replenishment pipeline 3 2. The rotary drainage pipe 32 is coaxially arranged with the liquid level measuring pipe 2, and a cleaning mechanism 31 is provided on the rotary drainage pipe 32; the inductive water replenishing device 5 is installed on the water replenishing pipe 3, and the monitoring end of the inductive water replenishing device 5 is installed on the liquid level measuring pipe 2; the float water replenishing valve 4 is installed on the water replenishing pipe 3, and the float water replenishing valve 4 includes a self-cleaning float 41 installed on the rotary drainage pipe 32, the self-cleaning float 41 is connected to the control end of the float water replenishing valve 4, and buoyancy spacing mechanisms 42 are installed on both sides of the self-cleaning float 41.

[0041] The pipe positioning frame 6 is first firmly installed inside the water seal well 1 to determine the installation position of the liquid level measuring tube 2. The liquid level measuring tube 2 is vertically installed on the pipe positioning frame 6, and its bottom is equipped with a conical filter layer 21 to filter impurities and prevent impurities from entering the inside of the measuring tube. The water supply pipe 3 is connected to the top of the liquid level measuring tube 2. At the same time, the rotating drainage pipe 32 is coaxially installed with the liquid level measuring tube 2. A cleaning mechanism 31 is provided on the rotating drainage pipe 32 for regular cleaning. The inductive water supply device 5 is installed on the water supply pipe 3, and the monitoring end of the inductive water supply device 5 is inside the liquid level measuring tube 2 to monitor the water level changes in real time. The float water supply valve 4 is installed on the water supply pipe 3, and the self-cleaning float 41 is connected to the rotating drainage pipe 32 through the buoyancy spacing mechanism 42 to ensure the floating stability of the self-cleaning float 41.

[0042] When the water level inside the water seal well 1 changes, the change in water level will directly affect the water level inside the liquid level measuring tube 2. The monitoring end of the inductive water replenishment device 5 captures this change in real time and converts it into an electrical signal for processing. The self-cleaning float 41 floats with the rise and fall of the water level inside the liquid level measuring tube 2. The buoyancy spacing mechanism 42 is used to adjust the floating frequency of the self-cleaning float 41 to ensure that the self-cleaning float 41 can stably stay in the specified position before losing buoyancy, avoiding excessively frequent water replenishment operations of the float water replenishment valve 4.

[0043] When the water level inside the water seal well 1 drops and causes the self-cleaning float 41 to lose its buoyancy, the self-cleaning float 41 will drop and trigger the float water replenishment valve 4, which will then open, allowing water to flow from the water replenishment pipe 3 through the rotating drainage pipe 32 into the water seal well 1 for water replenishment.

[0044] The rotating drainage pipe 32 rotates during the water replenishment process, driving the cleaning mechanism 31 to rotate synchronously, and the cleaning mechanism 31 cleans the inside of the liquid level measuring tube 2 and the conical filter layer 21 to prevent the accumulation of impurities from affecting the measurement accuracy. At the same time, the rotation of the rotating drainage pipe 32 also drives the self-cleaning float 41 to rotate, realizing the self-cleaning of the surface of the self-cleaning float 41.

[0045] If the float water supply valve 4 is damaged due to long-term use, the monitoring end of the induction water supply device 5 will automatically open the water supply pipe 3 after detecting the water level drop, so as to ensure the continuity and stability of water supply.

[0046] Through the dual monitoring and water replenishment mechanism of the monitoring end of the induction water replenishment device 5 and the self-cleaning float 41, the device can ensure timely water replenishment when the water level of the water seal well 1 drops, while avoiding water replenishment failure caused by single component failure. The design of the self-cleaning mechanism effectively extends the service life of the device and reduces measurement errors and water replenishment failures caused by impurity accumulation.

[0047] See also Figure 1 and Figure 3As shown, the cleaning mechanism 31 includes a first rotating frame 311 and a second rotating frame 312 installed on the rotating drainage pipe 32, and the first rotating frame 311 and the second rotating frame 312 are both provided with a first cleaning strip 313. The first rotating frame 311 is arranged inside the liquid level measuring tube 2, and the second rotating frame 312 is arranged on the outside of the conical filter layer 21.

[0048] The cleaning mechanism 31 includes a first rotating frame 311 and a second rotating frame 312 installed on the rotating drainage pipe 32, both of which are provided with a first cleaning strip 313. The first rotating frame 311 is arranged inside the liquid level measuring tube 2, and the first cleaning strip 313 thereon rotates with the rotation of the rotating drainage pipe 32, scrapes and cleans the inner wall of the liquid level measuring tube 2, and cleans the monitoring end of the sensing water replenishment device 5 at the same time, avoids impurity accumulation, and ensures the accuracy of detection.

[0049] The second rotating frame 312 is arranged on the outside of the conical filter layer 21, and the first cleaning strip 313 thereon rotates with the rotation of the rotating drainage pipe 32 to scrape and clean the outer wall of the conical filter layer 21 to ensure the fluidity of the conical filter layer 21 and prevent clogging by impurities.

[0050] See also Figures 1 to 6 As shown, one end of the rotating drainage pipe 32 is connected to the water supply pipe 3, a water flow driving blade 321 is installed inside the rotating drainage pipe 32, a first slide groove 322 is provided on the outer side of the rotating drainage pipe 32, a second slide groove 323 is provided on the end of the rotating drainage pipe 32 away from the water supply pipe 3, and a rotating drainage head 324 is also provided on the end of the rotating drainage pipe 32 away from the water supply pipe 3.

[0051] The rotating drainage pipe 32 is coaxially arranged with the liquid level measuring tube 2, one end of which is connected to the water supply pipe 3, and the other end is provided with a rotating drainage head 324. A water flow driving blade 321 is installed inside the rotating drainage pipe 32. When the water flows from the inside of the rotating drainage pipe 32, the water flow driving blade 321 is affected by the water flow to generate self-rotational energy, causing the rotating drainage pipe 32 to rotate. When the rotating drainage pipe 32 rotates, the rotating drainage head 324 rotates synchronously. When the rotating drainage head 324 rotates, it will suck the water inside the liquid level measuring tube 2 and discharge it outward, ensuring that the dirt deposited at the bottom of the liquid level measuring tube 2 can be discharged to the outside of the liquid level measuring tube 2.

[0052] A first chute 322 is provided on the outer side of the rotary drainage pipe 32 for installation with the self-cleaning float 41 to ensure that the self-cleaning float 41 can stably rotate with the rotary drainage pipe 32. A second chute 323 is provided at one end of the rotary drainage pipe 32 away from the water supply pipe 3 for installation with the rotary drainage head 324.

[0053] See also Figures 1 to 5As shown, the rotary drainage head 324 is arranged on the outside of the rotary drainage pipe 32, and a discharge gap is provided between the rotary drainage head 324 and the rotary drainage pipe 32. A rotating resistance ring 329 is installed on the outside of the rotary drainage head 324. A plurality of inclined collecting ports 325 are also provided on the outside of the rotary drainage head 324. The rotary drainage head 324 also includes a floating sealing head installed on the second slide groove 323. The floating sealing head includes a blocking blade 328 installed in the second slide groove 323. The floating sealing head also includes a sealing ring 326 sleeved on the outside of the rotary drainage pipe 32. The sealing ring 326 is fixedly connected to the blocking blade 328, and a floating block 327 is also installed on the sealing ring 326.

[0054] The rotary drainage head 324 is sleeved on the outside of the rotary drainage pipe 32, and a certain discharge gap is formed between the rotary drainage head 324 and the rotary drainage pipe 32. A rotary abutment ring 329 is installed on the outer surface of the rotary drainage head 324, and the rotary abutment ring 329 is used to abut against the bottom of the liquid level measuring tube 2 to ensure the stability of the rotary drainage head 324 in the installed state.

[0055] When the rotary drainage pipe 32 performs water replenishment operation, the rotary drainage pipe 32 drives the rotary drainage head 324 to rotate synchronously. At the same time, the water flow inside the rotary drainage pipe 32 flows through the blocking blade 328, and the blocking blade 328 moves downward after being impacted by the water flow. The downward movement of the blocking blade 328 further drives the blocking ring 326 and the floating block 327 fixedly connected thereto to descend synchronously, so that the blocking ring 326 opens the bottom of the rotary drainage head 324.

[0056] As the rotary drain head 324 rotates, the multiple inclined collection ports 325 on its outer side rotate, so that the water flow position at the bottom of the liquid level measuring tube 2 forms a suction effect, collects and compresses the water flow into the discharge gap. Subsequently, the sucked water flow is discharged through the bottom of the rotary drain head 324, thereby effectively discharging the dirt at the bottom of the liquid level measuring tube 2.

[0057] When the rotating drainage pipe 32 stops replenishing water, the floating block 327 will push the sealing ring 326 upward without the impact of water flow, thereby blocking the discharge gap. This effectively prevents the water inside the water seal well 1 from directly flowing back from the discharge gap to the liquid level measuring pipe 2 when replenishing water stops, ensuring the stability and reliability of the device.

[0058] See also Figures 3 to 9As shown, a sliding cleaning frame 414 is installed at the axial position of the self-cleaning float 41, the sliding cleaning frame 414 is rotatably connected to the self-cleaning float 41, the sliding cleaning frame 414 is slidably connected to the first slide groove 322 of the rotating drainage pipe 32, a plurality of second cleaning strips 415 are provided on the sliding cleaning frame 414, the second cleaning strips 415 are in contact with the outer wall of the self-cleaning float 41, a plurality of docking sliders 411 are provided on the outer side of the self-cleaning float 41, the docking slider 411 is slidably connected to the buoyancy spacer mechanism 42, a sliding guide rod 412 is installed on the docking slider 411, a connecting sleeve 413 is installed on the sliding guide rod 412, and the connecting sleeve 413 is connected to the control end of the float water supply valve 4.

[0059] A sliding cleaning frame 414 is installed at the axial position of the self-cleaning float 41. The sliding cleaning frame 414 is slidably connected to the first slide groove 322 of the rotating drainage pipe 32. When the rotating drainage pipe 32 rotates, the sliding cleaning frame 414 will be driven to rotate synchronously. The second cleaning strip 415 on the sliding cleaning frame 414 will scrape and clean the surface of the self-cleaning float 41 to ensure the cleanliness of the surface of the self-cleaning float 41 and prevent impurities from affecting the accuracy of detection.

[0060] At the same time, a plurality of docking sliders 411 are provided on the outside of the self-cleaning float 41, and the docking sliders 411 are slidably connected to the buoyancy spacing mechanism 42. The buoyancy spacing mechanism 42 is used to adjust the floating frequency of the self-cleaning float 41 to ensure that the self-cleaning float 41 can stably stay in the specified position before losing buoyancy. When the self-cleaning float 41 moves up and down, it will push the control end of the float water replenishment valve 4 to move through the sliding guide rod 412 and the connecting sleeve 413. When the water level inside the water seal well 1 drops and causes the self-cleaning float 41 to lose buoyancy, the self-cleaning float 41 will drop and trigger the float water replenishment valve 4, which will then open, allowing water to flow from the water replenishment pipe 3 through the rotating drainage pipe 32 into the water seal well 1 for water replenishment.

[0061] The float water supply valve 4 is prior art and will not be described in detail here.

[0062] See also Figure 3 and Fig.10 As shown, the buoyancy spacing mechanism 42 includes a plurality of limiting guide rails 421 symmetrically installed on both sides of the self-cleaning float 41 , and elastic guide strips 422 are symmetrically installed inside the limiting guide rails 421 , and extrusion channels are provided between the elastic guide strips 422 .

[0063] The outer side of the self-cleaning float 41 is provided with a plurality of docking sliders 411, and the docking sliders 411 are slidably connected with the buoyancy spacing mechanism 42. The buoyancy spacing mechanism 42 includes a plurality of limit rails 421 symmetrically installed on both sides of the self-cleaning float 41, and the inside of the limit rails 421 are symmetrically installed with elastic guide strips 422, and an extrusion channel is formed between the elastic guide strips 422. During the lifting process, the self-cleaning float 41 can stay stably at the designated position before losing buoyancy through the extrusion effect of the elastic guide strips 422, and the floating frequency of the self-cleaning float 41 is effectively adjusted. Avoid excessively frequent water replenishment operation of the float water replenishment valve 4, and effectively improve the service life.

[0064] See also Figures 1 to 4 As shown, the inductive water replenishment device 5 includes a first liquid level sensor 51 and a second liquid level sensor 52 installed on the side of the liquid level measuring tube 2 , and the inductive water replenishment device 5 also includes a solenoid valve 53 installed on the water replenishment pipeline 3 .

[0065] The inductive water replenishment device 5 includes a first liquid level sensor 51 and a second liquid level sensor 52 installed on the side of the liquid level measuring tube 2, and a solenoid valve 53 installed on the water replenishment pipe 3. The first liquid level sensor 51 is located below the self-cleaning float 41, and is used to monitor the liquid level inside the liquid level measuring tube 2 in real time. When the float water replenishment valve 4 cannot replenish water due to a malfunction, and the water level drops below the detection range of the first liquid level sensor 51, the solenoid valve 53 automatically opens, allowing water to flow through the water replenishment pipe 3 into the water seal well 1, ensuring the continuity and stability of water replenishment. The second liquid level sensor 52 is used to detect whether the water level in the water seal well 1 is too high. If the water level is too high, it means that the water replenishment is abnormal and the staff needs to check it in time.

[0066] See also Figures 1 to 10 As shown, the pipeline positioning frame 6 includes a correction positioning seat 62 for installing the liquid level measuring tube 2, and a synchronous expansion support mechanism 61 is installed on the outer side of the correction positioning seat 62. The synchronous expansion support mechanism 61 includes a limit fixing plate 611, and a plurality of vertical limit sliding grooves 6111 are provided on the limit fixing plate 611. The interiors of the vertical limit sliding grooves 6111 are all installed with sliding mounting blocks 618. A first pushing driving block 613 is installed on the top of the limit fixing plate 611, and a driving plate 612 is installed on the limit fixing plate 611. A plurality of driving inclined grooves 6121 are provided on the driving plate 612, and the driving inclined grooves 6121 are in conflict with the sliding mounting block 618. A second pushing driving block 614 is installed on the top of the driving plate 612, and an adjusting screw 615 is installed between the second pushing driving block 614 and the first pushing driving block 613. A telescopic adjusting rod 616 is installed on the sliding mounting block 618, and an anti-slip contact plate 617 is installed on the extending end of the telescopic adjusting rod 616.

[0067] The pipeline positioning frame 6 is mainly composed of a correction positioning seat 62 and a synchronous expansion support mechanism 61. The correction positioning seat 62 is used to fix the liquid level measuring tube 2 to ensure the stability and accuracy of the measuring tube. The synchronous expansion support mechanism 61 is responsible for firmly installing the entire pipeline positioning frame 6 at a designated position inside the water seal well 1. A plurality of vertical limiting grooves 6111 are provided on the limiting fixed disk 611, and the sliding mounting block 618 can move freely in the vertical limiting grooves 6111. The first push drive block 613 is rotatably connected to the limiting fixed disk 611, and the second push drive block 614 is rotatably connected to the drive disk 612. The adjusting screw 615 is connected between the first push drive block 613 and the second push drive block 614 to adjust the distance between the two.

[0068] When the liquid level measuring tube 2 needs to be installed at a designated position, the staff first uses the hoisting equipment to place the synchronous expansion support mechanism 61 as a whole to the designated position inside the water seal well 1. Then, by rotating the adjusting screw 615, the second push drive block 614 moves under the drive of the adjusting screw 615, thereby driving the driving disk 612 to rotate. The driving inclined groove 6121 on the driving disk 612 conflicts with the sliding mounting block 618. As the driving disk 612 rotates, the driving inclined groove 6121 pushes the sliding mounting block 618 to telescopically move in the vertical limiting slide groove 6111. The movement of the sliding mounting block 618 further drives the telescopic adjustment rod 616 to move synchronously. The extension end of the telescopic adjustment rod 616 is equipped with an anti-skid contact plate 617, and the anti-skid contact plate 617 finally contacts the inner wall of the water seal well 1, thereby realizing the positioning and installation of the entire pipeline positioning frame 6. Not only the stability and accuracy of the liquid level measuring tube 2 are ensured, but also the convenience and firmness of installation are greatly improved.

[0069] After the installation is completed, the staff can also install an anti-fall pull rope, connect one end of the pull rope to the pipe positioning frame 6, and the other end to the wellhead edge of the water seal well 1 to further prevent the pipe positioning frame 6 from slipping and ensure the safe operation of the device.

[0070] See also Figures 1 to 3 As shown, the correction positioning seat 62 includes a fixed ring 621 installed at the axial position of the limiting fixed disk 611, the inner wall of the fixed ring 621 is provided with a movable groove, the interior of the fixed ring 621 is installed with a movable mounting ring 622, and the outer side of the movable mounting ring 622 is provided with an arc surface, which matches the movable groove.

[0071] The correction positioning seat 62 includes a fixed collar 621 installed at the axial position of the limiting fixed disk 611, and a movable groove is provided on the inner wall of the fixed collar 621. The movable groove provides a small-angle movable space for the internal movable mounting ring 622. The outer side of the movable mounting ring 622 is provided with an arc surface matching the movable groove, ensuring that the movable mounting ring 622 can rotate and adjust to a certain extent inside the fixed collar 621.

[0072] The main function of the movable mounting ring 622 is to be fixedly mounted on the upper end of the liquid level measuring tube 2. After the synchronous expansion support mechanism 61 is positioned and installed at the designated position inside the water seal well 1, the synchronous expansion support mechanism 61 may not be able to completely maintain a horizontal state due to various factors such as uneven ground, installation errors, etc. However, since the upper end of the liquid level measuring tube 2 is connected to the movable mounting ring 622, under the influence of gravity, the liquid level measuring tube 2 will naturally sag and guide the movable mounting ring 622 to perform corrective movements. The correction process ensures that the liquid level measuring tube 2 can always remain in a vertical state and is not affected by the slight tilt that may exist in the synchronous expansion support mechanism 61. Therefore, no matter how the installation environment changes, the device can ensure the stability and accuracy of the liquid level measuring tube 2, thereby further improving the reliability and accuracy of the entire automatic water replenishment device.

[0073] An automatic water replenishment system for a water seal well based on liquid level monitoring comprises the following steps;

[0074] S1, the monitoring end of the induction water replenishment device 5 continuously monitors the water level changes inside the liquid level measuring tube 2, the water level changes are captured in real time and converted into electrical signals, and the system analyzes the electrical signals to obtain the current water level value;

[0075] S2. Compare the current water level with the preset safe water level range. If the water level is lower than the lower limit of the safe water level, it is determined that water replenishment is required.

[0076] S3, if the float water supply valve 4 functions normally, water flows into the water seal well 1 through the water supply pipe 3 and the rotary drainage pipe 32, the self-cleaning float 41 floats with the rise and fall of the water level, and the buoyancy spacing mechanism 42 ensures its floating stability to avoid excessive and frequent water supply operations;

[0077] S4. During the water replenishment process, the rotating drainage pipe 32 rotates, driving the cleaning mechanism 31 to rotate synchronously, cleaning the inside of the liquid level measuring tube 2 and the conical filter layer 21. At the same time, the rotation of the rotating drainage pipe 32 also drives the self-cleaning float 41 to rotate, realizing self-cleaning of the surface of the self-cleaning float 41;

[0078] S5. When the water level reaches the upper limit of the safe water level, the float water supply valve 4 is closed, the water supply is stopped, and the system continues to monitor the water level to ensure that the water level remains within a safe range;

[0079] S6. If the float water replenishment valve 4 is damaged due to long-term use or other reasons, the monitoring end of the induction water replenishment device 5 will automatically trigger the backup water replenishment mode after detecting that the water level continues to drop, that is, directly control the water replenishment pipe 3 to open for water replenishment.

[0080] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
