Description

Technical Field

[0001] The present invention belongs to the technical field of hydrological monitoring, and particularly relates to a hydrological forecasting device with an emergency device. Background Art

[0002] Hydrological forecasting devices are modern technical systems that integrate sensing, transmission, and analysis. Hydrological forecasting devices can, through real-time monitoring and analysis of hydrological data, more accurately predict the occurrence of natural disasters such as floods and droughts, provide a basis for flood control decision-making, rationally allocate water resources, and optimize water conservancy dispatching strategies.

[0003] Some existing hydrological forecasting devices are placed in the river channel for a long time to monitor the flow velocity and flow rate of the water in the river channel. However, due to some waterweeds and garbage in the water being easily accumulated at the hydrological forecasting device along with the water flow, it not only affects the measurement of the water flow velocity and flow rate, but also under the long-term accumulation of floating objects in the water, the cross-sectional area of the water channels on both sides of the hydrological forecasting device changes, resulting in a change in the water flow velocity on both sides of the hydrological forecasting device. When the water flow velocity difference on both sides of the hydrological forecasting device is relatively large, vortices are likely to be generated at the location of the hydrological forecasting device, which not only affects the stability of the hydrological forecasting device, but also causes the waterweeds and garbage in the water to further accumulate at the hydrological forecasting device, resulting in the inability of the hydrological forecasting device to work properly. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a hydrological forecasting device with an emergency device, aiming to solve the problem that under the long-term accumulation of floating objects in the water, the cross-sectional area of the water channels on both sides of the hydrological forecasting device changes, and at this time, vortices are likely to be generated at the location of the hydrological forecasting device, affecting the stability of the hydrological forecasting device.

The second electric telescopic sleeve is fixedly connected to the floating plate. The telescopic end of the second electric telescopic sleeve is fixedly connected with a sealing plate. The sealing plate is slidably and sealingly connected with the floating plate. The sealing plate can be magnetically attracted to the electromagnet ring.

[0007] In a further technical solution, the cleaning mechanism includes a third electric telescopic sleeve, a connecting sleeve, a cutter and a power assembly; The third electric telescopic sleeve is rotatably connected to the outer wall of the vertical rod. The electromagnet ring is fixedly connected to the telescopic end of the third electric telescopic sleeve. A plurality of cutters are fixedly connected to the telescopic end of the third electric telescopic sleeve. The telescopic end of the third electric telescopic sleeve is elastically slidably connected with a connecting sleeve. The connecting sleeve is fixedly connected with an upper gear disk. A lower gear disk is fixedly connected to the middle of the floating plate. A power assembly for driving the third electric telescopic sleeve to rotate is arranged on the strip-shaped plate.

[0008] In a further technical solution, the power assembly includes a third motor and a gear transmission pair. The third motor is fixedly connected to the strip-shaped plate. A gear transmission pair is arranged between the third motor and the third electric telescopic sleeve.

[0009] In a further technical solution, the guiding mechanism includes a first electric telescopic sleeve, a connecting plate, a second motor, an electric telescopic rod and a guiding plate; The first electric telescopic sleeve is fixedly connected to the vertical rod. The telescopic end of the first electric telescopic sleeve is fixedly connected with a connecting plate. Second motors are fixedly connected to both ends of the connecting plate.

[0010] In a further technical solution, a descaling assembly is further arranged outside the floating plate. The descaling assembly includes a worm gear and a scraping plate. The worm gear is rotatably connected to the outer wall of the floating plate. The worm gear is fixedly connected with a scraping plate. The scraping plate is attached to the outer wall of the floating plate.

[0011] In a further technical solution, the auxiliary limiting mechanism includes an elastic telescopic rod, a fixing plate and a limiting block; Both ends of the skateboard and the telescopic end of the electric telescopic plate are fixedly connected with elastic telescopic rods, and the telescopic ends of the elastic telescopic rods are fixedly connected with fixed plates. A plurality of limit blocks are arranged at the bottom of the fixed plates, and the limit blocks are rotationally connected to the fixed plates through elastic torsion springs. The limit blocks are tilted in the direction away from the vertical rod.

[0012] According to a further technical solution, the driving assembly includes a No. 1 motor and a gear, wherein the No. 1 motor is fixedly connected to the sleeve, and an output shaft of the No. 1 motor is fixedly connected to the gear, and the gear is meshed with the skateboard.

[0013] According to a further technical solution, the control system includes a data processor and a PLC controller, wherein the data processor is capable of comparing two measured flow rate differences with a preset flow rate difference threshold, and the PLC controller is electrically connected to the drive assembly, the flow guide mechanism, the sealing mechanism, the cleaning mechanism and the data processor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the velocity difference of the water flow on both sides of the floating plate is large, a vortex is likely to be generated around the floating plate. When the velocity on one side of the floating plate is small, the guide plate on this side of the floating plate is started to rotate, thereby increasing the flow area of the guide plate on this side of the floating plate, reducing the flow area of the river channel on this side of the floating plate, and then increasing the velocity of the water flow on this side of the floating plate. In this way, the water flow velocities on both sides of the floating plate are balanced; 2. When the cleaning mechanism cleans the garbage on the floating plate, the two No. 2 motors are started to drive the two guide plates to swing back and forth synchronously. At this time, the two guide plates are kept parallel. When the two guide plates swing toward one side of the river channel, the guide plate close to the inner wall of the river channel can guide the water flow to the inner wall of the river channel, so that the water flow cleans the garbage accumulated on the inner wall of the river channel. By cleaning the river channel on both sides of the floating plate, it is avoided that the garbage on both sides of the floating plate accumulates and affects the stability of the water flow near the floating plate. The guide plate far away from the inner wall of the river channel guides the water flow to the floating plate, so that the water flow can wash the floating plate from different directions; 3. When a vortex is generated in the water and the floating plate is sucked into the water, the No. 2 electric telescopic sleeve is first started to extend, and the No. 2 electric telescopic sleeve can drive the sealing plate to move downward, and the sealing plate releases the seal on the floating plate, thereby reducing the suction force of the vortex on the floating plate. After that, when the electromagnet ring is energized to adsorb the sealing plate, the sealing plate drives the floating plate to move up along the vertical rod and leave the water surface. At this time, the sealing plate releases the seal on the floating plate and can also remove the garbage accumulated on the upper side of the floating plate; 4. When the flow velocity difference between the two Doppler current meters is lower than the preset flow velocity difference threshold in the control system again, the third electric telescopic sleeve starts to extend. The third electric telescopic sleeve drives the upper gear disk to push the floating plate to sink into the water. At this time, the connecting sleeve elastically contracts in the third electric telescopic sleeve, and the second electric telescopic sleeve is started to drive the sealing plate to contract into the floating plate. Then, the power component is started to drive the upper gear disk to rotate, and the lower gear disk drives the floating plate to vibrate vertically reciprocally, so as to shake off the garbage attached to the outside of the floating plate. At the same time, the third electric telescopic sleeve drives the connecting sleeve to cut and break the garbage such as waterweeds wound around the floating plate, so as to avoid the influence of too large garbage attached to the floating plate on the monitoring result. At this time, the guide vane drives the water flow to flow upward, and the water flow passes through the floating plate to wash the garbage remaining on the upper side of the floating plate. At this time, the second electric telescopic sleeve is started to drive the sealing plate to reciprocate in the floating plate. Under the guiding action of the sealing plate, the water flow can continuously wash upward from the inside of the floating plate to different directions on the upper side, improving the washing effect on the garbage wound and piled up on the upper side of the floating plate.

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0018] The specific implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0019] As Figures 1-7 shown, a hydrological forecasting device with an emergency device provided by an embodiment of the present invention includes a vertical rod 1. The vertical rod 1 is provided with height marks along its length direction. The bottom of the vertical rod 1 is fixedly connected with a sliding sleeve 13. A spiral locator 16 is arranged at the bottom of the sliding sleeve 13. The spiral locator 16 is composed of a driving motor and a spiral blade. The spiral blade is fixedly connected with the output shaft of the driving motor. A sliding plate 14 is slidably connected to the sliding sleeve 13. A driving assembly 2 for driving the sliding plate 14 to move is arranged on the sliding sleeve 13. The sliding sleeve 13 is also fixedly connected with an electric telescopic plate 15. Auxiliary limiting mechanisms 3 are fixedly connected to both ends of the sliding plate 14 and the telescopic end of the electric telescopic plate 15; A floating plate 5 is slidably connected vertically on the vertical rod 1. A closing mechanism 6 capable of closing the bottom of the floating plate 5 is arranged in the floating plate 5. The side surface of the floating plate 5 is conical. A diversion mechanism 4 is also arranged on the vertical rod 1. The diversion mechanism 4 can divert the water flow; A strip plate 10 is fixedly connected to the top of the vertical rod 1. Doppler current meters 11 are fixedly connected to both ends of the strip plate 10. A cleaning mechanism 8 capable of moving vertically is arranged at the top of the vertical rod 1. The cleaning mechanism 8 can also clean the attachments wound on the upper side of the floating plate 5. The cleaning mechanism 8 is also connected with a diversion blade 12 and an electromagnet ring 9. The electromagnet ring 9 can generate a vertical suction force on the closing mechanism 6; A regulation system, which can regulate the driving assembly 2, the diversion mechanism 4, the closing mechanism 6 and the cleaning mechanism 8 according to the water flow velocity difference on both sides of the floating plate 5, so as to ensure the stability of the vertical rod 1 in the water flow.

[0020] Working principle: Keep the vertical rod 1 in a vertical state. Fix the vertical rod 1 by inserting the spiral locator 16 into the bottom of the river, so that the diversion mechanism 4 is located on the upstream side. At this time, the auxiliary limiting mechanisms 3 at both ends of the telescopic end of the electric telescopic plate 15 and the sliding plate 14 jointly support the vertical rod 1. At this time, the floating plate 5 floats on the water surface. Read the scale mark corresponding to the position of the floating plate 5 on the vertical rod 1 to determine the water surface height. Adjust the height of the diversion mechanism 4 so that the diversion mechanism 4 is kept on one side of the floating plate 5 to guide the water flow; Two Doppler current meters 11 at both ends of the strip plate 10 monitor the water flow velocity on both sides of the floating plate 5. When the velocity difference between the two Doppler current meters 11 exceeds the preset velocity difference threshold in the control system, a vortex is likely to be generated around the floating plate 5 at this time, causing the floating plate 5 and the garbage in the water to be sucked into the water by the downward suction force; Start the diversion mechanism 4, change the guiding angle of the water flow through the diversion mechanism 4, so as to regulate the water flow velocity on both sides of the floating plate 5. Start the electromagnet ring 9 to adsorb the closing mechanism 6, so that the closing mechanism 6 drives the floating plate 5 to rise along the vertical rod 1, the closing mechanism 6 is separated from the water surface, and start the closing mechanism 6 to release the sealing of the floating plate 5. At this time, the water flow resistance received by the floating plate 5 is reduced, and at the same time, it is avoided that too much garbage accumulates and tangles during the rising process of the floating plate 5; When the diversion mechanism 4 changes the guiding angle of the water flow, at this time, the water flow thrust received by the diversion mechanism 4 deflects to one side of the diversion mechanism 4. Start the driving component 2, and the driving component 2 drives the sliding plate 14 to slide along the sliding sleeve 13. The sliding sleeve 13 drives the auxiliary limiting mechanism 3 at one end to move to the side where the diversion mechanism 4 receives a greater force, so as to avoid the vertical rod 1 from deflecting under the water flow impact force; When the velocity difference between the two Doppler current meters 11 is lower than the preset velocity difference threshold in the control system again, at this time, start the electromagnet ring 9 to release the suction force on the closing mechanism 6, and push the floating plate 5 into the water through the cleaning mechanism 8. At this time, start the cleaning mechanism 8 to clean the attachments wound on the upper side of the floating plate 5. At the same time, the cleaning mechanism 8 drives the guide vane 12 to rotate, and the guide vane 12 drives the water flow to flow upward. The water flow passes through the floating plate 5 to wash the remaining garbage on the upper side of the floating plate 5; After the garbage on the floating plate 5 is cleaned up, at this time, the cleaning mechanism 8 resets, and the electromagnet ring 9 adsorbs the floating plate 5 out of the water again. At this time, start the closing mechanism 6 to seal the floating plate 5 again, and then place the floating plate 5 on the water surface again.

[0021] As Figure 6 shown, as a preferred embodiment of the present invention, the closing mechanism 6 includes a second electric telescopic sleeve 61 and a sealing plate 62. The second electric telescopic sleeve 61 is fixedly connected to the floating plate 5. The telescopic end of the second electric telescopic sleeve 61 is fixedly connected with a sealing plate 62. The sealing plate 62 is slidably and sealingly connected with the floating plate 5. The sealing plate 62 can be magnetically attracted to the electromagnet ring 9.

[0022] In this embodiment, when a vortex is generated in the water and the float 5 is sucked into the water, the No. 2 electric telescopic sleeve 61 is first started to extend, and the No. 2 electric telescopic sleeve 61 can drive the sealing plate 62 to move downward, and the sealing plate 62 releases the seal on the float 5, thereby reducing the suction force of the vortex on the float 5. After that, when the electromagnet ring 9 is energized and adsorbs the sealing plate 62, the sealing plate 62 drives the float 5 to move up along the vertical rod 1 and out of the water surface. At this time, the sealing plate 62 releases the seal on the float 5 and can also take away the garbage accumulated on the upper side of the float 5.

[0023] like Figure 5 As shown, as a preferred embodiment of the present invention, the cleaning mechanism 8 includes a No. 3 electric telescopic sleeve 81, a connecting sleeve 82, a cutter 83 and a power assembly 84; The No. 3 electric telescopic sleeve 81 is rotatably connected to the outer wall of the vertical rod 1, the electromagnet ring 9 is fixedly connected to the telescopic end of the No. 3 electric telescopic sleeve 81, the telescopic end of the No. 3 electric telescopic sleeve 81 is fixedly connected with a plurality of knives 83, the telescopic end of the No. 3 electric telescopic sleeve 81 is elastically and slidably connected with a connecting sleeve 82, the connecting sleeve 82 is fixedly connected with an upper toothed disc 85, the middle part of the floating plate 5 is fixedly connected with a lower toothed disc 86, and a power component 84 for driving the No. 3 electric telescopic sleeve 81 to rotate is provided on the strip plate 10.

[0024] In this embodiment, when the velocity difference between the two Doppler flowmeters 11 is lower than the velocity difference threshold preset in the control system again, the electromagnet ring 9 is started to cut off the power and release the suction force on the sealing plate 62. At this time, the floating plate 5 falls onto the water surface, and the No. 3 electric telescopic sleeve 81 is started to extend. The No. 3 electric telescopic sleeve 81 drives the upper gear plate 85 to push the floating plate 5 to sink into the water. At this time, the connecting sleeve 82 is elastically contracted in the No. 3 electric telescopic sleeve 81, and the No. 2 electric telescopic sleeve 61 is started to drive the sealing plate 62 to contract into the inside of the floating plate 5. Then, the power assembly 84 is started to drive the No. 3 electric telescopic sleeve 81 to rotate, and the No. 3 electric telescopic sleeve 81 drives the upper toothed disc 85 to rotate, and the upper toothed disc 85 rotates relative to the lower toothed disc 86. Under the downward thrust of the upper toothed disc 85 and the upward buoyancy of the water flow on the floating plate 5, the lower toothed disc 86 drives the floating plate 5 to vibrate vertically back and forth, thereby shaking off the garbage attached to the outside of the floating plate 5. At the same time, the No. 3 electric telescopic sleeve 81 drives the connecting sleeve 82 to cut and crush the garbage such as water plants wrapped around the floating plate 5, thereby avoiding excessive garbage attached to the floating plate 5 and affecting the monitoring results; At this time, the third electric telescopic sleeve 81 drives the guide vane 12 to rotate, and the guide vane 12 drives the water flow to flow upward. The water flow passes through the floating plate 5 to wash the garbage remaining on the upper side of the floating plate 5. At this time, the second electric telescopic sleeve 61 is started to drive the sealing plate 62 to reciprocate in the floating plate 5. Under the guiding action of the sealing plate 62, the water flow can continuously wash upward in different directions from the inside of the floating plate 5 to the upper side, improving the washing effect on the garbage wound and accumulated on the upper side of the floating plate 5.

[0025] As Figure 5 shown, as a preferred embodiment of the present invention, the power assembly 84 includes a third motor 841 and a gear transmission pair 842. The third motor 841 is fixedly connected to the strip plate 10, and a gear transmission pair 842 is arranged between the third motor 841 and the third electric telescopic sleeve 81.

[0026] In this embodiment, when the third motor 841 is started, the third motor 841 drives the third electric telescopic sleeve 81 to rotate through the gear transmission pair 842.

[0027] As Figure 3 shown, as a preferred embodiment of the present invention, the diversion mechanism 4 includes a first electric telescopic sleeve 41, a connecting plate 42, a second motor 43, an electric telescopic rod 44, and a diversion plate 45; The first electric telescopic sleeve 41 is fixedly connected to the vertical rod 1. The telescopic end of the first electric telescopic sleeve 41 is fixedly connected to the connecting plate 42. Both ends of the connecting plate 42 are fixedly connected to the second motor 43. The telescopic end of the second motor 43 is fixedly connected to the electric telescopic rod 44, and the electric telescopic rod 44 is fixedly connected to the diversion plate 45.

[0028] In this embodiment, when the velocity difference between the water flows on both sides of the floating plate 5 is large, a vortex is likely to be generated around the floating plate 5 at this time. When the velocity on one side of the floating plate 5 is small, the diversion plate 45 on this side of the floating plate 5 is started to rotate, so as to increase the flow-facing area of the diversion plate 45 on this side of the floating plate 5, reduce the flow-through area of the river channel on this side of the floating plate 5, and further increase the flow velocity of the water flow on this side of the floating plate 5. In this way, the flow velocities of the water flows on both sides of the floating plate 5 are balanced; When the cleaning mechanism 8 cleans the garbage on the floating plate 5, the two second motors 43 are started to drive the two diversion plates 45 to swing synchronously and reciprocally. At this time, the two diversion plates 45 are kept parallel. When the two diversion plates 45 swing towards one side of the river channel, the diversion plate 45 close to the inner wall of the river channel can guide the water flow towards the inner wall of the river channel, so that the water flow cleans the garbage accumulated at the inner wall of the river channel. By cleaning the river channels on both sides of the floating plate 5, it is avoided that the garbage accumulates on both sides of the floating plate 5 and affects the water flow stability near the floating plate 5, and the diversion plate 45 far from the inner wall of the river channel guides the water flow towards the floating plate 5, so that the water flow can wash the floating plate 5 from different directions.

[0029] As Figure 7 shown, as a preferred embodiment of the present invention, a descaling assembly 7 is further provided outside the floating plate 5. The descaling assembly 7 includes a worm gear 71 and a scraper 72. The worm gear 71 is rotatably connected to the outer wall of the floating plate 5, and the worm gear 71 is fixedly connected to the scraper 72. The scraper 72 is attached to the outer wall of the floating plate 5.

[0030] In the embodiment of the present invention, when water flow passes through the floating plate 5, the water flow pushes the worm gear 71 to rotate. The worm gear 71 drives the scraper 72 to clean the attachments on the side wall of the floating plate 5. When the worm gear 71 rotates, the worm gear 71 can push the garbage to one side and cooperate with the thrust of the water flow to take away the garbage, so as to ensure the accuracy of the floating plate 5 during monitoring.

[0031] As Figure 2 shown, as a preferred embodiment of the present invention, the auxiliary limiting mechanism 3 includes an elastic telescopic rod 31, a fixing plate 32 and a limiting block 33; Elastic telescopic rods 31 are fixedly connected to both ends of the sliding plate 14 and the telescopic ends of the electric telescopic plates 15. The telescopic ends of the elastic telescopic rods 31 are fixedly connected to the fixing plates 32. A plurality of limiting blocks 33 are arranged at the bottoms of the fixing plates 32. The limiting blocks 33 are rotatably connected to the fixing plates 32 through elastic torsion springs. The limiting blocks 33 are inclined in a direction away from the vertical rod 1.

[0032] In this embodiment, when the sliding plate 14 or the electric telescopic plate 15 drives the auxiliary limiting mechanism 3 to move to one side, at this time, the elastic telescopic rod 31 drives a row of limiting blocks 33 to move synchronously through the fixing plate 32. Under the elastic thrust of the elastic telescopic rod 31, the limiting blocks 33 are obliquely inserted into the water bottom, so as to improve the support stability effect on the vertical rod 1.

[0033] As Figure 2 shown, as a preferred embodiment of the present invention, the driving assembly 2 includes a first motor 21 and a gear 22. The first motor 21 is fixedly connected to the sliding sleeve 13. The output shaft of the first motor 21 is fixedly connected to the gear 22. The gear 22 meshes with the sliding plate 14.

[0034] In this embodiment, when the first motor 21 is started, the first motor 21 drives the gear 22 to rotate. The gear 22 pushes the sliding plate 14 to move horizontally along the sliding sleeve 13. When the flow-receiving area of one side of the flow deflector 45 is larger, at this time, the first motor 21 is started to drive the sliding plate 14 to move to the same side. The sliding plate 14 drives the auxiliary limiting mechanism 3 to move, so as to increase the supporting force on this side of the flow deflector 45 and avoid rotational deviation in the water when the two flow deflectors 45 are stressed inconsistently.

[0035] As a preferred embodiment of the present invention, the control system includes a data processor and a PLC controller. The data processor can compare the flow velocity difference measured by two Doppler flow velocity meters 11 with its preset flow velocity difference threshold value. The PLC controller is electrically connected to the driving assembly 2, the diversion mechanism 4, the closing mechanism 6, the cleaning mechanism 8 and the data processor.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
