TECHNICAL FIELD

[0001] The present application relates to the field of river flood control equipment, and particularly relates to a water level real-time monitoring mechanism for river flood control. BACKGROUND

[0002] In river flood control, water level real-time monitoring is crucial for early warning of flood disasters. At present, the widely used water level monitoring mechanism mainly sets a monitoring column with scale lines beside the river or the embankment, and the water level corresponding to the scale value is read by artificial visual reading. When reading the scale on the monitoring column, on the one hand, the scale is not obvious, and on the other hand, the water level reading on the monitoring column is lower than the river, which leads to great inconvenience in reading and easily delays the early warning and emergency response. SUMMARY

[0003] In order to improve the problem that the water level reading on the monitoring column is lower than the river, which leads to great inconvenience in reading and easily delays the early warning and emergency response.

As the buoyancy component rises with the water level, it drives the drive rod to rise via the intermediate rod. When the buoyancy component rises to the warning height, the drive rod extends into the drive hole of the bevel gear II within the mounting base II.

[0005] Furthermore, the connecting rod includes a fixed section connected to the driving rod and a connecting section connected to the connecting rod. The fixed section includes a base and two limiting parts. An assembly area is provided on the side of the base facing the connecting section. The two limiting parts are symmetrically arranged in the assembly area. A slide is provided in the assembly area along its width direction. A slider is integrally provided on the limiting part. An elastic element is fixedly installed between the slider and the inner wall of the slide. Under the action of the elastic element, the two limiting parts tend to move closer to each other. A connecting groove is provided in the assembly area, the connecting groove extends to one end of the fixed section facing the connecting section, and a drive section adapted to the connecting groove is integrally provided on the connecting section. A guide groove is provided at the top of the splicing position of the two limiting parts, and a guide component is fixed on the lower surface of the second mounting base; An adsorption element that works in conjunction with the mounting base is fixed on the fixed section.

[0006] Furthermore, a limiting block is integrally provided on the lower surface of the drive section, and a limiting groove is provided on the lower wall of the corresponding connecting groove, and the limiting block slides into the limiting groove.

[0007] Furthermore, the adsorption component includes a magnet one and a magnet two. The magnet one is fixed to the top of the fixing section, and a buffer spring is fixed between the magnet two and the fixing section. The upper surfaces of the magnet one and the magnet two are flush.

[0008] Furthermore, an installation area is vertically set on the monitoring column, the mounting base is installed in the installation area, and a shielding net is set on the water-facing side of the installation area, and the shielding net is fixed to the monitoring column.

[0009] Furthermore, the monitoring column is equipped with a cleaning mechanism for cleaning the shielding mesh. The cleaning mechanism includes a scraper adapted to the water-facing side of the shielding net and a drive assembly for driving the scraper to reciprocate up and down.

[0010] Furthermore, a driving cavity is vertically arranged inside the monitoring column, and the shielding mesh has a through hole along the vertical direction that communicates with the driving cavity. A reciprocating screw is arranged inside the driving cavity, and the screw of the reciprocating screw is vertically rotatably connected to the monitoring column.

A push spring is provided between the speed limiting component and the fixed section. Under the action of the push spring, the speed limiting component tends to extend into the additional hole. The speed limiter is provided with an upper guide surface at one end that extends into the additional hole; The speed limiting mechanism also includes an adjusting rod that is vertically fixed to the lower surface of the mounting base, and the adjusting rod is provided with a clearance hole; When the top of the drive rod approaches the drive hole of the bevel gear II within the mounting base II, the adjusting rod gradually abuts against the upper guide surface of the speed limiter and pushes the speed limiter to gradually abut against the drive rod, creating friction between the drive rod and the speed limiter, thus reducing the rotational speed of the drive rod. As the fixed section continues to rise, when the speed limiter aligns with the clearance hole, the speed limiter extends into the clearance hole. At this point, the speed limiter releases its restriction on the drive rod, and the drive rod returns to its normal rotational speed.

[0012] Furthermore, the speed limiter includes two solid parts and an intermediate spring, the intermediate spring being fixed between the two solid parts.

[0013] In summary, the present invention has at least the following beneficial effects: 1. By setting up a linkage indicator assembly consisting of buoyancy components, connecting rods, and ring indicators, and in conjunction with a graduated monitoring column and display, the changes in river water level are mapped into visual warning information in real time and intuitively, enabling people on the bank to clearly identify the water level status and warning level from a distance. 2. By setting bevel gear transmission mechanisms, liftable drive rods, and sound-generating components in the mounting base one and mounting base two, the effect of automatically triggering graded alarm mechanisms when the water level rises to different warning heights is achieved, realizing automated response from daily monitoring to flood warning; 3. By setting a detachable fixed section and connecting section structure for the intermediate rod, a cooperating mechanism for the guide and limiting parts, and a magnetic adsorption and buffer spring assembly, the driving rod can smoothly engage with the upper alarm mechanism when the water level is high and reliably separate and reset when the water level drops, thus ensuring the stability of the system's long-term operation and the reliability of repeated triggering.

[0016] This application provides a real-time water level monitoring mechanism for river flood control, referring to... Figure 1 and Figure 2 The system includes a vertically installed monitoring column 1 with vertically installed scale lines. A display element 11 is vertically fixed to the top of the monitoring column 1 with vertically installed scale lines. Several display areas 111 are arranged on the display element 11 from top to bottom. The signs in the display areas 111 can be automatically marked according to the water level in the river channel, such as serious warning, general warning, warning, normal, and low level from top to bottom.

[0017] An indicator component 12 is provided between the display component 11 and the monitoring column 1. The indicator component 12 is used to map the water level in the river channel onto the display component 11 for easy observation. Specifically, the indicator component 12 includes a vertical rail 121 fixed to the monitoring column 1. The rail 121 can be a vertically arranged channel steel. In this case, the rail 121 is a collar 1211, which is fixed to the monitoring column 1 by a rod.

[0018] The indicator assembly 12 also includes a connecting rod 122 that is vertically slidably installed within the track 121. A buoyancy element 123, typically an airbag, is fixed to the bottom of the connecting rod 122. An indicator element 124 is fixed to the top of the connecting rod 122. The indicator element 124 slides against the surface of the display element 11. To allow people to observe the water level indication on the display element 11 from 360 degrees, the indicator element 124 is a ring structure fitted around the periphery of the display element 11.

[0019] By setting a display component 11 and an indicator component 12 on the monitoring column 1, the buoyancy component 123 in the indicator component 12 rises or falls with the rise and fall of the water level in the river. During this process, the buoyancy component 123 pushes the indicator component 124 to rise and fall through the connecting rod 122, which allows people on the bank to clearly and intuitively observe the changes in the water level in the river, making it easier for people to carry out early warning work.

[0020] Reference Figure 3 and Figure 4 The monitoring column 1 is equipped with two sets of mounting seats 2. For ease of description, the two mounting seats 2 are named mounting seat one 21 and mounting seat two 22 respectively in this case. Mounting seat one 21 is located below mounting seat two 22.

[0021] Reference Figure 5 Specifically, the mounting base 2 includes a hollow mounting platform 3 fixedly mounted to the monitoring column 1. The mounting platform 3 has a mounting cavity 31, and a transmission assembly is installed within the mounting cavity 31. The transmission assembly includes a bevel gear set a32, which includes a first bevel gear 321 and a second bevel gear 322 rotatably connected to the mounting platform 3. The first bevel gear 321 is vertically positioned, and the second bevel gear 322 is horizontally positioned on the water-facing side of the first bevel gear 321. The first bevel gear 321 and the second bevel gear 322 mesh with each other. A polygonal drive hole 3221 is coaxially formed on the second bevel gear 322, and a corresponding vertical connecting hole 33 is formed on the mounting platform 3, aligned with the drive hole 3221.

[0022] Reference Figure 1 , 3 and Figure 5 The mounting base 3 of the mounting base 21 is rotatably connected to the back side of the mounting plate 3. The shaft of the drive blade 211 extends into the mounting cavity 31 and is fixed coaxially with the bevel gear 322.

[0023] Reference Figure 6 A transmission rod 222 is installed in the mounting cavity 31 of the mounting base 22. The transmission rod 222 is coaxially fixed to the back side of the bevel gear 322. A transmission rod 223 is installed at the end of the transmission rod 222 away from the bevel gear 322. The transmission rod 223 is rotatably connected to the fixed platform 3, and a bevel gear set b224 is installed between the transmission rod 223 and the transmission rod 222.

[0024] The monitoring column 1 has a cavity 13, and a sound-generating component 131 is fixed inside the cavity 13. The sound-generating component 131 includes a sound-generating element 1311 and an elastic element 1312 fixed between the sound-generating element 1311 and the inner wall of the cavity 13. The sound-generating element 1311 is generally a gong. The transmission rod 223 extends into the cavity 13, and a number of striking elements 2231 are fixed to the part of the transmission rod 223 that extends into the cavity 13. The number of striking elements 2231 are evenly arranged around the axis of the transmission rod 223.

[0025] A polygonal drive rod 4 is provided between mounting base 1 21 and mounting base 22, and the drive rod 4 is adapted to drive hole 3221. An intermediate rod 5 is provided between drive rod 4 and connecting rod 122. One end of the drive rod 4 is rotatably connected to the intermediate rod 5, and the other end of the intermediate rod 5 is fixed to the connecting rod 122. The bottom end of the drive rod 4 slides through the connecting hole 33 and drive hole 3221 on mounting base 1 21.

[0026] The water flow in the river channel drives the drive blade 211 to rotate continuously. The drive blade 211 drives the drive rod 4 to rotate through the bevel gear set a32 in the mounting base 1 21. When the water level in the river channel rises during the flood season, the buoyancy component 123 drives the drive rod 4 to rise as the water level in the river channel rises. When the water level in the river channel reaches the warning value, the drive rod 4 is inserted into the drive hole 3221 of the bevel gear 2 322 in the mounting base 2 22. The bevel gear set a32 in the mounting base 2 22 drives the transmission rod 1 222 and the transmission rod 2 223 to rotate. During the rotation of the transmission rod 2 223, the striking component 2231 on the transmission rod 2 223 will continuously strike the sound-emitting component 1311 to form an alarm and raise the awareness of safety of people on the bank.

[0027] Reference Figure 3 The monitoring column 1 has a vertically opened sound channel to ensure that the sound in the arrangement cavity 13 can be transmitted smoothly. The bottom end of the sound channel is connected to the arrangement cavity 13, and the top of the sound channel is provided with a sound outlet 14 that communicates with the outside. By setting the sound outlet 14 at the top of the monitoring column 1, water can be prevented from entering the arrangement cavity 13 as much as possible.

[0028] Reference Figure 7 and Figure 8Furthermore, the intermediate rod 5 includes a fixed section 51 and a connecting section 52. The drive rod 4 is rotatably connected to the fixed section 51, and the connecting section 52 is connected to the connecting rod 122. The fixed section 51 includes a base part 511 and two limiting parts 512. The base part 511 is connected to the drive rod 4. The base part 511 has an assembly area 5111 for mounting the two limiting parts 512. The two limiting parts 512 are symmetrically arranged within the assembly area 5111. A slide rail 5111a is formed along the width direction within the assembly area 5111. A slider 5121 adapted to the slide rail 5111a is integrally provided on each limiting part 512. The slider 5121 is slidably connected to the slide rail 5111a, and an elastic element 5121a is fixed between the slider 5121 and the slide rail 5111a. Under the action of the elastic element 5121a, the two limiting parts 512 tend to move closer to each other.

[0029] A connecting groove 5111b is provided at the end of the assembly area 5111 away from the drive rod 4. The connecting groove 5111b extends to the end of the base part 511 away from the drive rod 4. A drive section 521 adapted to the connecting groove 5111b is integrally provided on the corresponding connecting section 52. The drive section 521 slides into the connecting groove 5111b.

[0030] A guide groove 5122 is provided at the splicing position of the two limiting parts 512, and a guide member 224 with a triangular cross section is fixed on the lower surface of the corresponding mounting base 22 to cooperate with the guide groove 5122.

[0031] The fixed section 51 is fixed with an adsorption component 513 that works in conjunction with the mounting base 22. The adsorption component 513 is generally a magnet.

[0032] During the process of the buoyancy component 123 driving the intermediate rod 5 to rise through the connecting rod 122, when the intermediate rod 5 moves close to the mounting base 22, as the intermediate rod 5 continues to move upward, the guide component 224 gradually enters the guide groove 5122 and pushes the two limiting parts 512 to both sides. When the lower surface of the intermediate rod 5 contacts the lower surface of the mounting base 22, the two limiting parts 512 are completely pushed open. At this time, the drive section 521 can continue to move upward between the two limiting parts 512, thereby allowing the buoyancy component 123 to drive the connecting section 52 of the intermediate rod 5 to continue to float upward. This will not affect the normal operation of the device. When the intermediate rod 5 abuts against the lower surface of the mounting base 22, the adsorption component 513 adsorbs the fixed section 51 of the intermediate rod 5 to the mounting base 22, ensuring that the drive rod 4 can continuously drive the bevel gear 322 in the mounting base 22 to continue to move, thereby continuously releasing alarm signals.

[0033] As the water level gradually decreases, the buoyancy component 123 drives the connecting section 52 of the intermediate rod 5 to descend via the connecting rod 122. When the connecting section 52 descends into the connecting groove 5111b of the fixed section 51, as the buoyancy continues to decrease, the driving section 521 pushes the fixed section 51 to detach from the mounting base 22. During the process of the fixed section 51 gradually detaching from the mounting base 22, the two limiting parts 512 move towards each other under the action of the elastic component 5121a, thus restricting the driving section 521. In this process, in order to ensure the stability of the intermediate rod 5, in this case, a limiting groove 5111c is formed on the lower wall of the connecting groove 5111b, and a limiting block 5211 that cooperates with the limiting groove 5111c is integrally provided on the corresponding driving section 521. The limiting block 5211 is slidably connected to the limiting groove 5111c. The two limiting parts 512 limit the drive section 521 in the vertical direction, and the cooperation of the limiting block 5211 and the limiting groove 5111c limits the drive section 521 in the horizontal direction, thereby ensuring the stability of the intermediate rod 5.

[0034] Furthermore, the adsorption component includes a first magnet 5131 and a second magnet 5132. The first magnet 5131 is fixed to the upper surface of the fixing section 51, and a buffer spring 5133 is fixed between the second magnet 5132 and the upper surface of the fixing section 51. The upper surfaces of the first magnet 5131 and the second magnet 5132 are flush.

[0035] When the fixed section 51 is in contact with the lower surface of the mounting base 22, the magnet 5131 is attracted to the mounting base 22, fixing the mounting base 22 and the intermediate rod 5 together. The magnet 5132 is also attracted to the lower surface of the mounting base 22. When the buoyancy member 123 drives the upper part of the connecting section 52 and the fixed section 51 to descend through the connecting rod 122, when the driving section 521 enters the connecting groove 5111b, as the driving section 521 continues to push the fixed section 51 to descend, at the moment the fixed section 51 detaches from the mounting base 22, the cooperation of the magnet 5132 and the buffer spring 5133 can continue to provide a supporting force for the fixed section 51. This avoids the limitation part 512 from failing to instantly complete the reset due to the weakening elasticity of the elastic member 5121a after long-term use, thus limiting the driving section 521 and causing the fixed section 51 to fall, which would affect subsequent normal use.

[0036] Furthermore, in order to ensure the flatness of the upper surface of the fixed section 51, the upper surface of the fixed section 51 is provided with a first mounting groove 514 and a second mounting groove 515. The first magnet 5131 is installed in the first mounting groove 514, and the second magnet 5132 and the buffer spring 5133 are installed in the second mounting groove 515.

[0037] To better ensure the operation of the drive blade 211, a vertical mounting area 15 is provided in the middle of the monitoring column 1, and mounting base 1 21 and mounting base 22 are fixed to the mounting area 15. A shielding net 16 is provided on the water-facing side of the mounting area 15 and is fixed to the monitoring column 1. The shielding net 16 can block debris in the water flow, reducing the impact of debris on the drive blade 211.

[0038] In this case, the shielding net 16 is designed as an arc that curves towards the water-facing side to better adapt to the impact of the water flow in the river channel and enhance the stability of the shielding net 16.

[0039] Reference Figure 1 and Figure 9 The monitoring column 1 is equipped with a cleaning mechanism 6 for cleaning the shielding net 16.

[0040] Specifically, the cleaning mechanism 6 includes a scraper 61 disposed on the water-facing side of the shielding net 16, and a drive assembly 62 for driving the scraper 61 to move up and down reciprocally.

[0041] A drive chamber 17 is vertically arranged inside the monitoring column 1. A through hole 161 communicating with the drive chamber 17 is opened on the shielding mesh cover 16 along the vertical direction. A reciprocating screw 621 is installed inside the drive chamber 17. The screw of the reciprocating screw 621 is vertically rotatably connected to the monitoring column 1. The sliding sleeve 622 of the reciprocating screw 621 passes through the through hole 161 and is fixedly connected to the scraper 61.

[0042] A drive seat 63 is provided between mounting base 1 21 and mounting base 22. The drive seat 63 is fixedly installed to the monitoring column 1. A drive chamber 631 is provided inside the drive seat 63. A bevel gear set c632 is provided inside the drive chamber 631. The bevel gear set c632 includes a horizontal bevel gear 6321 and a vertical bevel gear 6322 that are rotatably connected to the drive seat 63. The horizontal bevel gear 6321 and the vertical bevel gear 6322 mesh together.

[0043] A through hole 6321a, which is adapted to the drive rod 4, is coaxially provided on the horizontal bevel gear 6321. A through hole 633, which is vertically provided on the drive seat 63, is aligned with the through hole 6321a. The drive rod 4 passes through the through hole 6321a and the through hole 633.

[0044] An output shaft 6322a is coaxially fixed on the vertical bevel gear 6322. The output shaft 6322a extends into the drive cavity 17. The output shaft 6322a is connected to the screw of the reciprocating lead screw 621 through a transmission rod and a gear set. The above transmission method is conventional existing technology and will not be described in detail in this case.

[0045] The water flow in the river channel drives the drive blade 211 to rotate. The drive blade 211 drives the drive rod 4 to rotate through the bevel gear set a32. The drive rod 4 drives the screw in the reciprocating screw 621 to rotate through the moving bevel gear set c632 and other structures, thereby realizing the scraper 61 to move up and down on the shielding net cover 16.

[0046] In addition, the drive seat 63 is located close to the mounting seat 21, and the drive rod 4 always passes through the first through hole 6321a and the second through hole 633, thereby ensuring that the scraper 61 can work continuously.

[0047] Reference Figure 10 The bottom of the mounting base 22 is provided with a speed limiting mechanism 7. The purpose of the speed limiting mechanism 7 is to reduce the speed of the drive rod 4 when it approaches the mounting base 22, so that the drive rod 4 can pass through the drive hole 3221 in the mounting base 22. After the drive rod 4 passes through the drive hole 3221 in the mounting base 22, the speed of the drive rod 4 returns to normal.

[0048] Specifically, a mounting hole 516 is provided inside the fixed section 51 along its own axis, and the mounting hole 516 communicates with the channel for mounting the drive rod 4. An additional hole 517 is also provided on the fixed section 51 along the vertical direction, and the additional hole 517 communicates with the mounting hole 516.

[0049] The limiting mechanism includes a speed limiting member 72 that is slidably installed into the mounting hole 516. A push spring 721 is provided between the speed limiting member 72 and the fixed section 51. Under the action of the push spring 721, the speed limiting member 72 tends to extend into the auxiliary hole 517. The end of the speed limiting member 72 that extends into the mounting hole 516 is provided with an upper guide surface 724 and a lower guide surface 725.

[0050] The speed limiting mechanism 7 also includes an adjusting rod 71 that is vertically fixed to the lower surface of the mounting base 22. The adjusting rod 71 is located above the fixed section 51, and the adjusting rod 71 is located between the guide 224 and the connecting hole 33 on the mounting base 22. The adjusting rod 71 is adapted to the additional hole 517, and a clearance hole 711 is vertically provided on the adjusting rod 71.

[0051] When the top of the drive rod 4 approaches the drive hole 3221 of the bevel gear 322 inside the mounting base 22, the adjusting rod 71 gradually abuts against the upper guide surface 724 of the speed limiter 72, and gradually pushes the speed limiter 72 against the drive rod 4 through the upper guide surface 724, so that friction is formed between the drive rod 4 and the speed limiter 72, thereby reducing the speed of the drive rod 4 and facilitating the drive rod 4 to pass through the drive hole 3221 inside the mounting base 22. As the fixed section 51 continues to rise, when the drive rod 4 extends into the drive hole 3221 inside the mounting base 22, the adjusting rod 71 slides to disengage. As the upper guide surface 724 moves away, the speed limiter 72 extends into the clearance hole 711. At this time, the speed limiter 72 releases the restriction on the drive rod 4, and the drive rod 4 resumes its normal rotation speed. After the speed limiter 72 extends into the clearance hole 711, the fixed section 51 will drive the drive rod 4 to continue to rise. During this process, in order to avoid interference between the clearance hole 711 and the speed limiter 72 and the rise of the fixed section 51, it is necessary to ensure that the height of the top of the clearance hole 711 is sufficient to allow the fixed section 51 to move to the lower surface of the mounting base 22. In this case, the top of the clearance hole 711 extends to the lower surface of the mounting base 2.

[0052] As the fixed section 51 continues to descend, when the lower guide surface 725 contacts the bottom of the clearance hole 711, it gradually pushes the speed limiter 72 against the drive rod 4, causing friction between the drive rod 4 and the speed limiter 72. This reduces the rotational speed of the drive rod 4, achieving deceleration and allowing the drive rod 4 to smoothly disengage from the drive hole 3221. As the drive rod 4 completely disengages, the adjusting rod 71 disengages from the speed limiter 72, and the speed limiter 72 resets and extends into the mounting hole 516, releasing the friction restriction on the drive rod 4. The drive rod 4 then resumes its normal rotational speed and returns to its initial state.

[0053] Furthermore, the speed limiter 72 includes two solid parts 722 and an intermediate spring 723. The intermediate spring 723 is fixed between the two solid parts 722. When the speed limiter 72 causes friction against the drive rod 4, the intermediate spring 723 can play a buffering role, making the entire deceleration process more stable.

[0054] The implementation principle of this application is as follows: the monitoring column 1 senses water level changes through the buoyancy component 123. The buoyancy component 123 drives the connecting rod 122 and the annular indicator 124 to move up and down along the scale display component 11, realizing an intuitive and visual display of the water level status. When the water level rises from a low position, it first triggers the mechanism in the mounting base 21 located at the lower position: the water flow pushes the drive blade 211 of the mounting base 21 to rotate, which drives the drive rod 4 passing through it to rotate through the bevel gear set a32 inside. This rotational power is transmitted to the drive seat 63 located above the mounting base 21, which ultimately drives the scraper 61 of the cleaning mechanism 6 to reciprocate through the bevel gear set c632 therein, realizing continuous self-cleaning. When the water level continues to rise to a preset higher warning height, the top of the drive rod 4 pushed by the buoyancy component 123 will rise and insert into the drive hole 3221 of the horizontal bevel gear 6321 located in the mounting base 22 above. At this point, the alarm transmission chain within mounting base 22 is activated: the rotational power generated by the impact of the river water flow on the drive blade 211 at mounting base 21 is transmitted to the coaxial transmission rod 222 via the internal bevel gear set a32, and then to the transmission rod 223 via the bevel gear set b224, ultimately causing the striking element 2231 fixed on the transmission rod 223 to periodically strike the sound-emitting element 1311, producing an alarm sound. When the drive rod 4 rises with the water level and approaches mounting base 222, the guide element 224 fixed at the bottom of mounting base 222 will open the two limiting parts 512 of the fixing section 51 of the intermediate rod 5, allowing the drive rod 4 to continue to move upward; at the same time, the magnet 5131 on the upper surface of the fixing section 51 will be attracted and fixed to the lower surface of mounting base 222, ensuring a stable transmission connection. When the water level drops, the connecting section 52 presses down on the fixing section 51, disengaging it from the mounting base 22. The limiting part 512, under elastic force, resets and locks the driving section 521, achieving smooth separation. Furthermore, the speed limiting mechanism 7 at the bottom of the mounting base 22, through the cooperation of the adjusting rod 71 and the speed limiting component 72, provides frictional deceleration when the driving rod 4 inserts into and exits its driving hole 3221, ensuring smooth engagement and disengagement. In summary, this system is designed with a complete automatic connection, locking, disengagement, and buffering mechanism, achieving full-process automation from water level monitoring, visual warning, graded triggering to equipment self-maintenance, significantly improving the real-time performance and reliability of river flood control monitoring.
