Description

Technical Field

[0001] This invention relates to the field of riverbank monitoring technology, specifically to a monitoring device and method for monitoring flooding of riverbank sections. Background Technology

[0002] River embankments are water-retaining structures built along the banks of rivers to prevent flooding and block tides and waves. With the continuous development of society, river embankments are no longer just water-retaining structures. With the premise of "protecting and creating a good living environment and natural landscape for organisms", while taking into account a certain strength, safety and durability, river embankments have been transformed from the past artificial concrete structures into river embankments where water, soil and organisms mutually nourish each other, making them suitable for the growth of organisms.

[0003] During spring and summer, increased rainfall can easily cause river levels to rise and overflow embankments, flooding farmland and houses. Therefore, it is necessary to install water level monitoring equipment on river embankments to issue alarms when the water level rises to a certain height during the flood season, allowing for advance preparation for flood prevention. However, water level monitoring equipment is only used during the spring and summer flood season. Under normal circumstances, the water level does not change much. Existing monitoring equipment is usually directly fixed on the river embankment, which means it is constantly submerged in water, which greatly affects the lifespan of the water level monitoring equipment.

[0004] Based on this, the present invention designs a monitoring device and method for flooding of river embankment sections, in order to solve the problem that the above-mentioned water level monitoring equipment on the river embankment can only be used during the flood season in spring and summer, while being fixed in the water all year round affects its service life.

The support rod is spirally connected to the first locking rods and the locking sleeves. A slot is provided on the support rod, a suspended ball is provided inside the support rod, an indicator light is provided at the top of the support rod, and an impurity cleaning component is provided on the suspended ball. The impurity cleaning component is used to clean out impurities that enter the interior of the support rod during flooding, preventing blockage inside the support rod from affecting the normal floating of the suspended ball.

[0007] As a further embodiment of the present invention, the impurity cleaning assembly includes a telescopic rod fixed to the bottom of a support rod. A base plate is fixedly connected to the top of the output shaft of the support rod. A protrusion is fixedly connected to one side of the base plate.

A limiting rail with one end protruding outward is fixedly connected to the bottom of the base plate. Collection frames are fixedly connected to both sides of the bottom of the second toothed ring. A sliding plate is slidably connected inside the collection frame. A sliding groove is formed at the top of the collection frame. A dial shaft is slidably connected to the top of the sliding plate. The top of the dial shaft passes through the sliding groove and engages with the inside of the limiting rail.

[0008] As a further embodiment of the present invention, the surface of the telescopic rod is provided with a scale line layer.

[0009] As a further embodiment of the present invention, an adjusting sleeve is slidably connected to the top of the support rod, and a second locking rod is fixedly connected to both sides of the top of the support rod. The adjusting sleeve has mating grooves on both sides for mating with the second locking rod. The signal light is fixed to the top of the adjusting sleeve. A connecting rod is fixedly connected inside the adjusting sleeve. A power supply module is fixedly connected to the bottom of the connecting rod. A pressure sensor is fixedly connected to the bottom of the power supply module. The output end of the pressure sensor is electrically connected to the signal light through the power supply module.

[0010] As a further embodiment of the present invention, fasteners are fixedly connected to both sides of the top of the cement base.

[0011] As a further embodiment of the present invention, one end of the collection frame is fixedly connected to a downwardly extending connecting piece.

[0012] As a further embodiment of the present invention, the top of the cement base is provided with a slot for docking with the support rod, and the outer wall of the support rod can be completely fitted with the inner wall of the slot.

[0014] A method for monitoring flooding at river embankment cross-sections, the method comprising the following steps:

[0015] Step 1: During installation and use, insert the support rod into the lock sleeve and downward into the signal light, and then fix the support rod to the lock sleeve using the first locking rod;

[0016] Step 2: After the support rod is fixed, water will enter the support rod through the slot, and the suspended ball will float on the water surface to monitor the water level;

[0017] Step 3: As the water level rises, the height of the suspended ball also increases. When it reaches the warning height, the indicator light will flash.

[0018] Step 4: As the suspended ball rises, the impurity cleaning component cleans the impurities floating on the liquid surface inside the support rod, preventing them from affecting the suspension of the ball. After the water level drops, the suspended ball will reset.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention uses a cement base as a fixing component submerged in water. A support rod for detecting water level is fixed to the cement base via a spiral connection. During the flood season, the support rod can be directly installed on the cement base for water level detection. After the flood season, the support rod can be removed from the cement base. This avoids the support rod being permanently fixed in the water, preventing damage to the equipment caused by prolonged immersion. Moreover, during the flood season, if the water is not clean, a large amount of algae will bloom, which can seriously affect the suspension alarm of the suspended ball. The impurity cleaning component can clean out the suspended impurities inside the support rod as the suspended ball slides, effectively preventing the impact of algae blooms on the suspended ball during the flood season.

[0031] Please see Figure 1-8 This invention provides a technical solution: a monitoring device for flooding of a river embankment section, comprising a cement base 4, a fixed rod 6 fixedly connected to the top of the cement base 4, a locking sleeve 7 fixedly connected to the top of the fixed rod 6, a support rod 3 connected inside the cement base 4, a first locking rod 11 fixedly connected to both sides of the support rod 3, the support rod 3 being spirally connected to the first locking rod 11 and the locking sleeve 7, a slot 5 being provided on the support rod 3, a suspended ball 10 being provided inside the support rod 3, an indicator light 1 being provided at the top of the support rod 3, and an impurity cleaning component being provided on the suspended ball 10. The impurity cleaning component is used to clean out impurities that enter the interior of the support rod 3 during flooding, preventing blockage inside the support rod 3 from affecting the normal floating of the suspended ball 10.

[0032] When the above solution is put into practical use, during installation, the cement base 4 is sunk to the riverbed and adjusted to be placed horizontally. The support rod 3 is inserted downwards into the signal light 1, connected to the locking sleeve 7. Then, the support rod 3 is fixed to the locking sleeve 7 by the first locking rod 11. After the support rod 3 is fixed, water will enter the support rod 3 through the slot 5. The suspended ball 10 is suspended on the water surface to monitor the water level. When the water level rises, the height of the suspended ball 10 also rises. When the suspended ball 10 reaches the warning height, the signal light 1 will flash an alarm. When the suspended ball 10 rises, the impurity cleaning component will clean the impurities floating on the liquid surface inside the support rod 3 to avoid affecting the suspension of the suspended ball 10. After the water level drops, the suspended ball 10 will reset. The advantage of this design is that by using the cement base 4 as a fixing component submerged in the water, the support rod 3 for detecting the water level is fixed to the cement base 4 via a spiral connection. When the flood season arrives, the support rod 3 can be directly installed on the cement base 4 for water level detection. After the flood season ends, the support rod 3 can be removed from the cement base 4. This way, the support rod 3 does not need to be fixed in the water indefinitely, avoiding damage to the equipment caused by long-term immersion. Moreover, during the flood season, if the water is not clean enough, a large amount of algae will bloom in the water, which may seriously affect the suspension alarm of the suspended ball 10. The impurity cleaning component can clean out the suspended impurities inside the support rod 3 as the suspended ball 10 slides, effectively preventing the impact of algae blooms on the suspended ball 10 during the flood season.

[0033] As a further embodiment of the present invention, the impurity cleaning assembly includes a telescopic rod 9, which is fixed to the bottom of a support rod 3. A base plate 19 is fixedly connected to the top of the output shaft of the support rod 3. A suspended ball 10 is fixed to the top of the base plate 19. A first toothed ring 18 is rotatably connected to the bottom of the base plate 19. A protrusion is fixedly connected to one side of the first toothed ring 18. A spiral groove that mates with the protrusion is opened inside the support rod 3. A second toothed ring 22 is rotatably connected to the top of the telescopic rod 9. A transmission gear 20 that meshes with the first toothed ring 18 and the second toothed ring 22 is rotatably connected to the bottom of the base plate 19. A limiting rail 21 with one end protruding outward is fixedly connected to the bottom of the base plate 19. Collection frames 17 are fixedly connected to both sides of the bottom of the second toothed ring 22. A sliding plate 25 is slidably connected inside the collection frame 17. A groove 24 is opened at the top of the collection frame 17. A dial 23 is slidably connected to the top of the sliding plate 25. The top of the dial 23 passes through the groove 24 and mates with the inside of the limiting rail 21.

[0034] When the above scheme is put into practical use, during the flood season when the water level rises, the liquid level inside the support rod 3 through the slot 5 rises synchronously, causing the suspended ball 10 to rise synchronously with the liquid level. The rise of the suspended ball 10 drives the telescopic rod 9 and the first toothed ring 18 to slide upward. When the first toothed ring 18 slides upward, because the protrusion on one side of it connects with the spiral groove inside the support rod 3, the first toothed ring 18 also rotates during its rise. The rotation of the first toothed ring 18 drives the transmission gear 20 to rotate, and the transmission gear 20 drives the second toothed ring 22 to rotate. The second toothed ring 22 drives the bottom collection frame 17 to rotate. During the rotation of the collection frame 17, impurities floating on the liquid surface will enter the collection frame 17 through the opening. When the second toothed ring 22 rotates to the point where the pivot shaft 23 slides along the outer protrusion of the limiting track 21, the pivot shaft 23 will push the sliding plate 25 inside the collection frame 17 to slide to one end, thereby collecting the impurities. The impurities collected inside the collection frame 17 are pushed to the other end. When the pivot 23 drives the sliding plate 25 to slide to the maximum position, the opening on one side of the collection frame 17 is exactly aligned with the slot 5. At this time, the impurities inside the collection frame 17 can be transported along the slot 5 to the outside of the support rod 3. Then, the pivot 23 will continue to slide along the limit track 21 to reset the sliding plate 25. The advantage of this is that since the rise of the liquid level is not very fast, the rotation speed of the first toothed ring 18 is very slow. However, due to the transmission of the transmission gear 20 and the rotation of the second toothed ring 22, the rotation speed of the second toothed ring 22 is much faster than that of the first toothed ring 18. In this way, the impurities inside the support rod 3 can be transported to the outside of the support rod 3 by rotating the collection frame 17. This can effectively prevent the algae from accumulating inside the support rod 3 and affecting the floating of the suspended ball 10 during the flood season when the water body is eutrophic and algae blooms.

[0035] As a further embodiment of the present invention, the surface of the telescopic rod 9 is provided with a scale line layer;

[0036] When the above scheme is put into practical use, the changes in water level can be observed more intuitively and accurately through the scale lines.

[0037] As a further embodiment of the present invention, an adjusting sleeve 2 is slidably connected to the top of the support rod 3, and a second locking rod 12 is fixedly connected to both sides of the top of the support rod 3. The adjusting sleeve 2 has docking grooves 13 on both sides for docking with the second locking rod 12. The signal light 1 is fixed to the top of the adjusting sleeve 2. A connecting rod 14 is fixedly connected inside the adjusting sleeve 2. A power supply module 15 is fixedly connected to the bottom of the connecting rod 14. A pressure sensor 16 is fixedly connected to the bottom of the power supply module 15. The output end of the pressure sensor 16 is electrically connected to the signal light 1 through the power supply module 15.

[0038] When the above scheme is put into actual use, when the water level rises to the warning position, the suspended ball 10 will slide upward to the position where it contacts the pressure sensor 16. The pressure sensor 16 senses the pressure and activates the power supply module 15 to output the control signal light 1 to alarm. When the adjusting sleeve 2 is installed on the support rod 3, in order to adapt to the warning water level of different river embankments, the adjusting sleeve 2 can be adjusted to a suitable height on the support rod 3, and then tightened and fixed by the second locking rod 12. The adjustable adjusting sleeve 2 can adapt to river embankments with different warning water levels.

[0039] As a further embodiment of the present invention, fasteners 8 are fixedly connected to both sides of the top of the cement base 4;

[0040] When the above scheme is put into practical use, the buckle 8 can be used to install and sink the cement seat 4 to the bottom. When the cement seat 4 is sunk to the bottom of the water, the external lifting equipment can be connected to the buckle 8 to sink the cement seat 4 to the bottom of the river, and the position of the cement seat 4 can be easily adjusted to keep it horizontal at the bottom of the water.

[0041] As a further embodiment of the present invention, a downwardly extending connecting piece 26 is fixedly connected to one end of the collection frame 17;

[0042] When the above solution is put into actual use, the connecting piece 26 enables the collection frame 17 to expand the cleaning surface when it rotates, so that more impurities can be transported into the collection frame 17 and then cleaned out.

[0043] As a further embodiment of the present invention, the top of the cement base 4 is provided with a slot for docking with the support rod 3, and the outer wall of the support rod 3 can be completely fitted with the inner wall of the slot.

[0044] When the above solution is put into actual use, the two parts fit together perfectly, making the support rod 3 more stable when it is inserted into the cement seat 4, thus avoiding the problem of shaking that could affect the water level detection of the suspended ball 10.

[0045] As a further embodiment of the present invention, the collection frame 17, the first toothed ring 18 and the bottom plate 19 are all made of a material with a density less than that of water;

[0046] When the above solution is put into actual use, the collection frame 17, the first toothed ring 18 and the bottom plate 19 can all have a certain buoyancy and float on the water surface, so as to avoid the weight of the collection frame 17, the first toothed ring 18 and the bottom plate 19 affecting the suspension of the suspended ball 10.

[0047] A method for monitoring flooding at river embankment cross-sections, the method comprising the following steps:

[0048] Step 1: During installation and use, insert the support rod 3 into the lock sleeve 7 and downward into the signal light 1, and then fix the support rod 3 to the lock sleeve 7 by the first locking rod 11;

[0049] Step 2: After the support rod 3 is fixed, water will enter the interior of the support rod 3 through the slot 5, and the suspended ball 10 will float on the water surface to monitor the water level;

[0050] Step 3: When the water level rises, the height of the suspended ball 10 also increases. When it reaches the warning height, the signal light 1 will flash.

[0051] Step 4: When the suspended ball 10 rises, the impurity cleaning component will clean the impurities floating on the liquid surface inside the support rod 3 to avoid affecting the suspension of the suspended ball 10. After the water level drops, the suspended ball 10 will reset.

[0052] Working principle: During installation and use, the cement base 4 is sunk to the bottom of the river and its position is adjusted to be placed horizontally. The support rod 3 is connected to the inside of the locking sleeve 7 and inserted downward into the signal light 1. Then, the support rod 3 is fixed to the locking sleeve 7 by the first locking rod 11. After the support rod 3 is fixed, water will enter the support rod 3 through the slot 5. The suspended ball 10 is suspended on the water surface to monitor the water level. When the water level rises, the height of the suspended ball 10 also rises. When the water level rises to the warning position, the suspended ball 10 will slide upward to the position of contact with the pressure sensor 16. The pressure sensor 16 senses the pressure and activates the power supply module 15 to output control signal light 1 to alarm.

[0053] During the flood season, when the water level rises, the liquid level inside the support rod 3 through the slot 5 rises synchronously, causing the suspended ball 10 to rise synchronously with the liquid level. The rise of the suspended ball 10 drives the telescopic rod 9 and the first toothed ring 18 to slide upwards. As the first toothed ring 18 slides upwards, its protrusion on one side engages with the spiral groove inside the support rod 3, causing the first toothed ring 18 to rotate simultaneously during its ascent. The rotation of the first toothed ring 18 drives the transmission gear 20 to rotate, which in turn drives the second toothed ring 22 to rotate. The second toothed ring 22 drives the bottom collection frame 17 to rotate. During the rotation of the collection frame 17, impurities floating on the liquid surface will enter the collection frame 17 through its opening. When the second toothed ring 22 rotates to the point where the pivot shaft 23 slides along the outer protrusion of the limiting track 21, the pivot shaft 23 will push the collection frame 17. The internal sliding plate 25 slides to one end, pushing the impurities collected inside the collection frame 17 to the other end. When the pivot 23 drives the sliding plate 25 to slide to the maximum position, the opening on one side of the collection frame 17 is exactly aligned with the slot 5. At this time, the impurities inside the collection frame 17 can be transported along the slot 5 to the outside of the support rod 3. Then, the pivot 23 will continue to slide along the limit track 21 to reset the sliding plate 25. The advantage of this is that since the liquid level rises slowly, the rotation speed of the first toothed ring 18 is very slow. However, due to the transmission of the transmission gear 20 and the rotation of the second toothed ring 22, the rotation speed of the second toothed ring 22 is much faster than that of the first toothed ring 18. In this way, the impurities inside the support rod 3 can be transported to the outside of the support rod 3 by rotating the collection frame 17.
