Description

Technical Field

[0001] This invention relates to the field of water level measuring device technology, and more specifically, to a self-flushing mica water level gauge. Background Technology

[0002] Currently, the conventional cleaning procedure for water level gauges is quite cumbersome. The specific steps are as follows: First, close both the water-side and air-side valves, and simultaneously open the drain valve. After opening the drain valve, open the air-side valve half a turn and use steam to flush the inside of the water level gauge for 5-10 minutes. After flushing, close the air-side valve, then open the water-side valve half a turn and flush the water level gauge again for 5-10 minutes. After completing the above flushing and draining operations, close the drain valve. Then, open both the water-side and air-side valves one-fifth of a turn each. Once the steam and water level have returned to normal, slowly alternately open the air-side and water-side valves until they are fully open. Only then is the cleaning process complete. Existing cleaning methods are complex, requiring operators to sequentially close water-side and air-side valves, open the drain valve, and then gradually open the air-side and water-side valves for flushing. After flushing, a series of valve closing and opening operations are necessary. The entire cleaning process involves multiple valve operations with strict requirements on the order of operations. Operators must strictly follow the steps and be familiar with the function of each valve, demanding a high level of operator proficiency and prone to errors. The entire operation takes 10-20 minutes or even longer, resulting in excessively long cleaning time and low efficiency. Therefore, we propose a self-flushing mica level gauge. Summary of the Invention

The size of the drive fan blade is adapted to the inner wall size of the connecting pipe, and the first bearing is snapped onto the outside of the frame assembly.

[0009] Preferably, the frame assembly includes an elastic telescopic rod, the bottom end of which is fixedly connected to a support frame, the support frame being L-shaped, and one side of the support frame being fixedly connected to a plurality of limiting sliders; The upper part of the support frame is engaged with the first bearing, several limiting sliders are slidably connected in the limiting groove, several cleaning components are engaged with one side of the support frame, and the top end of the elastic telescopic rod is fixedly connected to the upper part of the inner wall of the inner shell.

[0010] Preferably, the cleaning assembly includes a second bearing, a rotating shaft is sleeved inside the second bearing, a transmission gear and a half gear are fixedly connected to the outside of the rotating shaft, and a cleaner is fixedly connected to the other end of the rotating shaft; The second bearing is snapped onto one side of the support frame, the chain is wound around the transmission gear, and a second bevel gear is fixedly connected to the uppermost rotating shaft.

[0011] Preferably, the adjustment assembly includes a plurality of toothed plates, and the plurality of toothed plates are fixedly connected by a reinforcing plate, and a reinforcing rib is fixedly connected to one side of each of the plurality of toothed plates; The other side of the toothed plate meshes with the half gear, and the reinforcing rib is fixedly connected to one side of the inner wall of the inner shell.

[0012] Preferably, the support assembly includes a plurality of third bearings, and the plurality of third bearings are fixedly connected by a positioning plate; The third bearing is sleeved on the outside of the rotating shaft.

[0013] Preferably, the cleaner includes a connecting block, and a plurality of guide plates are fixedly connected to the outside of the connecting block. The guide plates are inclined, and a rubber scraper is fixedly connected to one side of the guide plate. One side of the connecting block is fixedly connected to the rotating shaft, and the rubber scraper overlaps with the mica sheet inside the panel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention designs control valves, pressure pumps, and drain valves. By closing the upper and lower control valves, the connection between the water level gauge mechanism and the boiler is severed. The pressure pump is then started, injecting pressure into the upper conduit to increase the pressure above the water level gauge mechanism. At this time, the liquid below the water level gauge mechanism enters the pressure pump along the conduit and then circulates again along the upper conduit, thus performing a preliminary flushing of the water level gauge mechanism. After cleaning, simply open the drain valve to discharge the cleaned liquid. After use, reopen the control valves on both sides. This operation method reduces the difficulty of using the device while ensuring its cleaning effect on the inside of the water level gauge mechanism.

[0015] 2. This invention also incorporates a housing assembly, a cleaning assembly, an adjusting assembly, and a transmission assembly. During the initial flushing, a large amount of liquid is injected into the housing assembly along the upper conduit and connecting pipe. Since the transmission assembly is located inside the connecting pipe, when the liquid is discharged along the connecting pipe, it drives the transmission assembly to rotate, which in turn drives the cleaning assembly to rotate. During the rotation of the cleaning assembly, it intermittently contacts the adjusting assembly, causing the frame assembly, cleaning assembly, and transmission assembly to continuously move downwards. When they are no longer in contact with the adjusting assembly, the frame assembly as a whole pulls the cleaning assembly and transmission assembly back to their original positions. The rotating cleaning assembly cleans the mica sheets inside the water level gauge. The reciprocating up-and-down movement of the cleaning components further enhances the cleaning effect on mica sheets. Through this reciprocating movement, the cleaning components can cover all areas of the mica sheet, including corners and edges that are difficult to reach with conventional single-movement methods, ensuring that the entire mica sheet is effectively cleaned and reducing cleaning dead spots. At the same time, the centrifugal force generated by the rotational motion combined with the mechanical force of the up-and-down movement can more effectively remove stubborn dirt, scale, or other deposits attached to the surface of the mica sheet. For impurities embedded in the tiny crevices of the mica sheet surface, this composite motion can produce a stronger peeling effect, achieving deep cleaning.

[0016] 3. This invention also designs a drive assembly, a cleaning assembly, and a frame assembly. When liquid enters the inner shell along the upper connecting pipe, the pressure generated by the liquid flow squeezes the drive fan blades, causing them to rotate. When the drive fan blades rotate, they drive the second bevel gear outside the uppermost rotating shaft to rotate via the first bevel gear, which in turn drives all rotating shafts to rotate via the transmission gears and chains. At the same time, the rotating shafts drive the connecting block, guide plate, and rubber scraper to clean the mica sheets inside the water level gauge. The friction generated by direct contact removes dirt from the mica sheets. Using a rubber scraper to clean the mica sheets further reduces the possibility of damage to the mica sheets during the cleaning process, improving the safety of the device during use.

[0019] like Figures 1 to 8 As shown, the present invention relates to a self-flushing mica level gauge, comprising a control valve 22, a conduit 23, a drain valve 25, and a mounting housing 111, and further comprising... The water level gauge mechanism 1 includes a housing assembly 11, two connecting pipes 12 connected to the housing assembly 11, a transmission assembly 13 located within the upper connecting pipe 12, a frame assembly 14 below the transmission assembly 13, several cleaning components 15, an adjusting assembly 16 located within the housing assembly 11, a support assembly 17 connected to the several cleaning components 15, and a chain 18, wherein the several cleaning components 15 are all connected to the frame assembly 14, and the several cleaning components 15 are connected by the chain 18; and a flow mechanism 2 includes two tees 21, a control valve 22 connected to the two tees 21, two conduits 23 connected to the two tees 21, a pressure pump 24, and a drain valve 25, wherein the two conduits 23 are both connected to the pressure pump 24, and the drain valve 25 is located on the lower tees 11. In addition to the control valve 21, by designing control valve 22, pressure pump 24 and drain valve 25, the upper and lower control valves 22 are closed to disconnect the water level gauge mechanism 1 from the boiler. The pressure pump 24 is started to inject pressure into the upper conduit 23, increasing the pressure above the water level gauge mechanism 1. At this time, the liquid below the water level gauge mechanism 1 enters the pressure pump 24 along the conduit 23 and then circulates again along the upper conduit 23, thus performing a preliminary flushing of the water level gauge mechanism 1. After cleaning, simply open the drain valve 25 to discharge the cleaned liquid. After use, open the control valves 22 on both sides again to ensure that the equipment can perform normal testing. This operation method reduces the difficulty of using the device while ensuring its cleaning effect on the inside of the water level gauge mechanism 1.

[0020] In an embodiment of the present invention, connecting pipes 12 are fixedly connected to both the upper and lower parts of the outer shell assembly 11. The inner wall of the upper connecting pipe 12 overlaps with the transmission assembly 13. The transmission assembly 13 is snapped into the frame assembly 14. The frame assembly 14 is fixedly connected to the upper part of the inner wall of the outer shell assembly 11. The frame assembly 14 is snapped into several cleaning components 15. The uppermost cleaning component 15 engages with the transmission assembly 13. The several cleaning components 15 are connected by a chain 18. The inner wall of the outer shell assembly 11 is fixedly connected to the adjustment assembly 16. The adjustment assembly 16 overlaps with the cleaning components 15. Each cleaning component 15 is snapped into the support component 17. The top and bottom of the outer casing component 11 are connected to a tee 21 via connecting pipes 12. One side of the tee 21 is connected to a conduit 23. The two conduits 23 are respectively connected to the top and bottom of the pressure pump 24. A drain valve 25 is located below the lower tee 21. Control valves 22 are installed outside both tee 21. Through the design of the outer casing component 11, cleaning component 15, adjusting component 16, and transmission component 13, during initial rinsing, a large amount of liquid flows along the upper conduit 23 and connecting pipe 12 into the outer casing component 11. Due to the transmission component... Component 13 is located inside the connecting pipe 12. When liquid is discharged along the connecting pipe 12, it drives the transmission component 13 to rotate, which in turn drives the cleaning component 15 to rotate. During the rotation of the cleaning component 15, it intermittently contacts the adjusting component 16, causing the frame assembly 14, the cleaning component 15, and the transmission component 13 to continuously move downwards. When they are no longer in contact with the adjusting component 16, the frame assembly 14 as a whole pulls the cleaning component 15 and the transmission component 13 back to their original positions. The rotating cleaning component 15 cleans the mica sheets inside the water level gauge. Combined with the reciprocating up-and-down movement of the cleaning component 15, further... This further improves the cleaning effect of the device on mica sheets. By moving back and forth, the cleaning component 15 can cover all areas of the mica sheet, including corners and edges that are difficult to reach with conventional single-motion methods, ensuring that the entire mica sheet is effectively cleaned and reducing cleaning dead spots. At the same time, the centrifugal force generated by the rotational motion combined with the mechanical force of the up-and-down movement can more effectively remove stubborn dirt, scale or other deposits attached to the surface of the mica sheet. For some impurities embedded in the tiny crevices of the mica sheet surface, this composite motion can produce a stronger peeling effect and achieve deep cleaning.

[0021] In an embodiment of the present invention, the outer shell assembly 11 includes a mounting shell 111, a panel 112 fixedly connected to the front of the mounting shell 111, an inner shell 113 fixedly connected inside the mounting shell 111, a limiting groove 114 formed on the inner wall of the inner shell 113, and two connecting pipes 12 respectively connected to the top and bottom of the inner shell 113. The transmission assembly 13 includes a drive fan blade 131, a connecting shaft 132 fixedly connected to the bottom of the drive fan blade 131, a first bearing 133 snapped onto the outside of the connecting shaft 132, and a first bevel gear 134 fixedly connected to the outside of the connecting shaft 132. The drive fan blade 131 adopts an arc-shaped design and is located inside the connecting pipe 12. The size of the drive fan blade 131 is adapted to the inner wall size of the connecting pipe 12. The first bearing 133 is snapped onto the outside of the frame assembly 14. By designing the drive assembly and cleaning... When liquid enters the inner shell 113 along the upper connecting pipe 12, the pressure generated by the liquid flow will squeeze and drive the fan blade 131, causing it to rotate. When the fan blade 131 rotates, it will drive the second bevel gear 153 outside the uppermost rotating shaft 152 to rotate through the first bevel gear 134. In turn, it will drive all rotating shafts 152 to rotate through the transmission gear 154 and the chain 18. At the same time, the rotating shafts 152 will drive the connecting block 1561, guide plate 1562 and rubber scraper 1563 to clean the mica sheets inside the water level gauge. The friction generated by direct contact is used to remove dirt from the mica sheets. The use of rubber scraper 1563 to clean the mica sheets can further reduce the possibility of damage to the mica sheets during the cleaning process and improve the safety of the device during use.

[0022] In another embodiment of the present invention, the frame assembly 14 includes an elastic telescopic rod 141. A support frame 142 is fixedly connected to the bottom end of the elastic telescopic rod 141. The support frame 142 is L-shaped. A plurality of limiting sliders 143 are fixedly connected to one side of the support frame 142. The top of the support frame 142 is engaged with a first bearing 133. The plurality of limiting sliders 143 are slidably connected in limiting grooves. A plurality of cleaning components 15 are engaged with one side of the support frame 142. The top end of the elastic telescopic rod 141 is fixedly connected to the top of the inner wall of the inner shell 113. The cleaning component 15 includes a second bearing 151. A rotating shaft 152 is sleeved inside the second bearing 151. A transmission gear 154 and a half gear 155 are fixedly connected to the outside of the rotating shaft 152. A cleaner 156 is fixedly connected to the other end of the rotating shaft 152. The second bearing 151 is engaged with one side of the support frame 142. A chain 18 is wound around the transmission gear 154. The uppermost rotating shaft 152 is fixedly connected to a second bevel gear 153, which meshes with the first bevel gear 134. When the rubber scraper 1563 is driven by multiple rotating shafts 152 to clean the mica sheet, the half gear 155 will continue to rotate. During the rotation of the half gear 155, when it comes into contact with the toothed plate 161, it will mesh with the toothed plate 161 and move down along the teeth on the surface of the toothed plate 161. At this time, the elastic telescopic rod 141 will gradually stretch. As the half gear 155 continues to rotate, when it disengages from the toothed plate 161, the elastic telescopic rod 141 will quickly pull the rotating shaft 152 and the cleaner 156 back to their original positions. This process is repeated. When the device is running, it can not only rotate around the rotating shaft 152 to clean the mica sheet, but also move vertically up and down in the vertical direction by multiple rotating shafts 152, thereby expanding the cleaning range of the mica sheet and avoiding the residue of impurities in dead corners.

[0023] In another embodiment of the present invention, the adjusting component 16 includes a plurality of toothed plates 161, which are fixedly connected by a reinforcing plate 162. A reinforcing rib 163 is fixedly connected to one side of each toothed plate 161, and the other side of each toothed plate 161 meshes with a half gear 155. The reinforcing rib 163 is fixedly connected to one side of the inner wall of the inner shell 113. The supporting component 17 includes a plurality of third bearings 171, which are fixedly connected by a positioning plate 172. The third bearings 171 are sleeved around the rotating shaft 152. The cleaner 156 includes a connecting block 1561, which is fixedly connected to the outside of the connecting block 1561. There are several guide plates 1562, which are inclined. A rubber scraper 1563 is fixedly connected to one side of the guide plate 1562. One side of the connecting block 1561 is fixedly connected to the rotating shaft 152. The rubber scraper 1563 overlaps with the mica sheet in the panel 112. By designing a third bearing 171 in multiple rotating shafts 152 and connecting and fixing the third bearing 171 with the positioning plate 172, the pressure caused by multiple rotating shafts 152 and support frame 142 during up and down movement is reduced, avoiding the possibility of damage to support frame 142, and thus ensuring the service life of the device.

[0024] Working principle: This embodiment provides a self-flushing mica water level gauge. When in use, close the upper and lower control valves 22 to disconnect the water level gauge mechanism 1 from the boiler. Start the pressure pump 24 and use the pressure pump 24 to inject pressure into the upper conduit 23, so that the pressure above the water level gauge mechanism 1 increases. At this time, the liquid below the water level gauge mechanism 1 enters the pressure pump 24 along the conduit 23 and then circulates again along the upper conduit 23, thereby performing a preliminary flushing of the water level gauge mechanism 1. After cleaning, simply open the drain valve 25 to discharge the cleaned liquid. After use, open the control valves 22 on both sides again. During the initial flushing, a large amount of liquid is injected into the housing assembly 11 along the upper conduit 23 and the connecting pipe 12. Since the transmission assembly 13 is located inside the connecting pipe 12, when the liquid is discharged along the connecting pipe 12, it will drive the transmission assembly 13 to rotate, which in turn will drive the cleaning assembly 15 to rotate. During the rotation of the cleaning assembly 15, it will intermittently contact the adjusting assembly 16, causing the frame assembly 14, the cleaning assembly 15, and the transmission assembly 13 to continuously move downward. When they no longer contact the adjusting assembly 16, the frame assembly 14 will pull the cleaning assembly 15 and the transmission assembly 13 back to their original positions. The rotating cleaning assembly 15 will clean the mica sheets inside the water level gauge. With the reciprocating up and down movement of the cleaning assembly 15, the cleaning effect of the device on the mica sheets is further improved. When the liquid enters the inner shell 113 along the upper connecting pipe 12, the pressure generated by the liquid flow will squeeze and drive the fan blade 131, causing it to rotate. When the fan blade 131 rotates, it will drive the second bevel gear 153 outside the uppermost rotating shaft 152 to rotate through the first bevel gear 134. In turn, it will drive all the rotating shafts 152 to rotate through the transmission gear 154 and the chain 18. At the same time, the rotating shafts 152 drive the connecting block 1561, the guide plate 1562 and the rubber scraper 1563 to clean the mica sheet inside the water level gauge, relying on the friction generated by direct contact to remove the dirt on the mica sheet. When the rubber scraper 1563 is driven by multiple rotating shafts 152 to clean the mica sheets, the half gear 155 will continue to rotate. During the rotation of the half gear 155, when it comes into contact with the toothed plate 161, it will mesh with the toothed plate 161 and move down along the teeth on the surface of the toothed plate 161. At this time, the elastic telescopic rod 141 will gradually stretch. As the half gear 155 continues to rotate, when it disengages from the toothed plate 161, the elastic telescopic rod 141 will quickly pull the rotating shaft 152 and the cleaner 156 back to their original positions, and so on.

Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
