Description

Technical Field

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

[0002] Hydrological forecasting equipment is a modern technology system that integrates sensing, transmission, and analysis. By monitoring and analyzing hydrological data in real time, it can more accurately predict the occurrence of natural disasters such as floods and droughts, providing a basis for flood prevention decisions, rationally allocating water resources, and optimizing water conservancy scheduling strategies.

[0003] Some existing hydrological forecasting equipment is placed in rivers for a long time to monitor the velocity and flow of water in the river. However, some aquatic plants and garbage in the water are easily accumulated at the hydrological forecasting equipment along with the water flow, which not only affects the measurement of water velocity and flow, but also the long-term accumulation of floating objects in the water causes the flow area of the waterway on both sides of the hydrological forecasting equipment to change, resulting in changes in the water velocity on both sides of the hydrological forecasting equipment. When the difference in water velocity on both sides of the hydrological forecasting equipment is large, vortices are easily generated at the hydrological forecasting equipment, which not only affects the stability of the hydrological forecasting equipment, but also causes aquatic plants and garbage in the water to further accumulate and gather at the hydrological forecasting equipment, resulting in the hydrological forecasting equipment being unable to work normally.‌ Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the flow velocity difference between the two sides of the floating plate is large, vortex flow is easily generated around the floating plate. When the flow velocity on one side of the floating plate is low, the guide plate on that side of the floating plate is activated to rotate, thereby increasing the flow area of the guide plate on that side of the floating plate, reducing the flow area of the river channel on that side of the floating plate, and thus increasing the flow velocity on that side of the floating plate. In this way, the flow velocity on both sides of the floating plate is balanced;

[0022] 2. When the cleaning mechanism is cleaning 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 can clean up the garbage accumulated on the inner wall of the river channel. By cleaning the river channel on both sides of the floating plate, the accumulation of garbage on both sides of the floating plate is avoided, which may affect the stability of the water flow near the floating plate. The guide plate away from the inner wall of the river channel guides the water flow to the floating plate, so that the water flow can flush the floating plate from different directions.

[0023] 3. When a vortex is generated in the water and the float is sucked into the water, the No. 2 electric telescopic sleeve is first activated to extend, which can drive the sealing plate downward, releasing the seal on the float, thereby reducing the suction of the vortex on the float. After that, when the electromagnet ring is energized and attracts the sealing plate, the sealing plate drives the float upward along the vertical rod and out of the water. At this time, the sealing plate releases the seal on the float and can also remove the garbage accumulated on the upper side of the float;

[0024] 4. When the velocity difference between the two Doppler flowmeters is lower than the velocity difference threshold preset in the control system again, the No. 3 electric telescopic sleeve is started to extend, and the No. 3 electric telescopic sleeve drives the upper gear disc to push the float plate into the water. At this time, the connecting sleeve elastically shrinks in the No. 3 electric telescopic sleeve, and the No. 2 electric telescopic sleeve is started to drive the sealing plate to shrink into the inside of the float plate; then the power component is started to drive the upper gear disc to rotate, and the lower gear disc drives the float plate to vibrate back and forth vertically, thereby shaking off the garbage attached to the outside of the float plate. At the same time, the No. 3 electric telescopic sleeve drives the connecting sleeve to cut and crush the water plants and other garbage wrapped around the float plate, thereby avoiding excessive garbage attached to the float plate and affecting the monitoring results; at this time, the guide blade drives the water flow upward, and the water flow passes through the float plate to flush the garbage remaining on the upper side of the float plate. At this time, the No. 2 electric telescopic sleeve is started to drive the sealing plate to move back and forth in the float plate. Under the guidance of the sealing plate, the water flow can continuously flush upward from the inside of the float plate in different directions, thereby improving the flushing effect of the garbage entangled and accumulated on the upper side of the float plate.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0035] like Figure 1-Figure 7 As shown, a hydrological forecasting device with an emergency device provided by an embodiment of the present invention includes a vertical rod 1, wherein the vertical rod 1 is provided with a height mark along the length direction, a sliding sleeve 13 is fixedly connected to the bottom of the vertical rod 1, a spiral positioner 16 is provided at the bottom of the sliding sleeve 13, and the spiral positioner 16 is composed of a drive motor and a spiral blade, and the spiral blade is fixedly connected to the output shaft of the drive motor, the sliding sleeve 13 is slidably connected to a slide plate 14, and a drive assembly 2 for driving the slide plate 14 to move is provided on the sliding sleeve 13, and the sliding sleeve 13 is further fixedly connected to an electric telescopic plate 15, and both ends of the slide plate 14 and the telescopic end of the electric telescopic plate 15 are fixedly connected to an auxiliary limiting mechanism 3;

[0036] A floating plate 5 is vertically slidably connected to the vertical rod 1. The floating plate 5 is provided with a closing mechanism 6 capable of closing the bottom of the floating plate 5. The side of the floating plate 5 is tapered. The vertical rod 1 is also provided with a diversion mechanism 4, which can divert the water flow.

[0037] The top of the vertical rod 1 is fixedly connected to a strip plate 10, and both ends of the strip plate 10 are fixedly connected to a Doppler flow meter 11. The top of the vertical rod 1 is provided with a cleaning mechanism 8 that can move vertically. The cleaning mechanism 8 can also clean the attachments wrapped around the upper side of the floating plate 5. The cleaning mechanism 8 is also connected to a guide vane 12 and an electromagnet ring 9. The electromagnet ring 9 can generate vertical suction on the closing mechanism 6.

[0038] The control system can control the driving assembly 2, the diversion mechanism 4, the closing mechanism 6 and the cleaning mechanism 8 according to the difference in water flow velocity on both sides of the floating plate 5, so as to ensure the stability of the vertical rod 1 in the water flow.

[0039] Working principle:

[0040] Keep the vertical rod 1 in a vertical state, insert the screw positioner 16 into the river bottom to fix the vertical rod 1, so that the diversion mechanism 4 is located on the flow-facing side. At this time, the auxiliary limit mechanisms 3 at the telescopic ends of the electric telescopic plate 15 and the two ends of the slide plate 14 jointly support the vertical rod 1. At this time, the floating plate 5 floats on the water surface. Read the scale mark at the corresponding position of the floating plate 5 on the vertical rod 1 to determine the water surface height, and adjust the height of the diversion mechanism 4 so that the diversion mechanism 4 remains on one side of the floating plate 5 to guide the water flow.

[0041] Two Doppler flowmeters 11 at both ends of the strip plate 10 monitor the water flow velocity on both sides of the floating plate 5. When the flow velocity difference between the two Doppler flowmeters 11 exceeds the flow velocity difference threshold preset in the control system, a vortex is likely to be generated around the floating plate 5, causing the floating plate 5 and the garbage in the water to be sucked into the water by the downward suction force.

[0042] The diversion mechanism 4 is activated to change the water flow angle by the diversion mechanism 4, thereby regulating the water flow rate on both sides of the floating plate 5. The electromagnet ring 9 is activated to attract 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 the closing mechanism 6 is activated to release the seal on the floating plate 5. At this time, the water flow resistance on the floating plate 5 is reduced, and at the same time, too much garbage is prevented from accumulating and entangled during the rising process of the floating plate 5.

[0043] When the guide mechanism 4 changes its guiding angle for the water flow, the water flow thrust on the guide mechanism 4 causes it to deflect to one side, and the driving assembly 2 is activated. The driving assembly 2 drives the slide plate 14 to slide along the sliding sleeve 13, and the sliding sleeve 13 drives the auxiliary limiting mechanism 3 at one end to move to the side of the guide mechanism 4 with greater force, thereby preventing the vertical rod 1 from deflecting under the impact of the water flow;

[0044] When the velocity difference between the two Doppler flowmeters 11 falls below the velocity difference threshold preset in the control system again, the electromagnet ring 9 is activated to release the suction force on the closing mechanism 6, and the floating plate 5 is pushed into the water through the cleaning mechanism 8. The cleaning mechanism 8 is then activated to clean the attachments entangled on the upper side of the floating plate 5. At the same time, the cleaning mechanism 8 drives the guide vanes 12 to rotate, and the guide vanes 12 drive the water flow upward. The water flows through the floating plate 5 to wash away the garbage remaining on the upper side of the floating plate 5.

[0045] When the garbage on the floating plate 5 is cleaned up, the cleaning mechanism 8 is reset, and the electromagnet ring 9 again absorbs the floating plate 5 from the water surface. At this time, the sealing mechanism 6 is started to reseal the floating plate 5, and then the floating plate 5 is placed on the water surface again.

[0046] like Figure 6 As shown, as a preferred embodiment of the present invention, the closing mechanism 6 includes a No. 2 electric telescopic sleeve 61 and a sealing plate 62. The No. 2 electric telescopic sleeve 61 is fixedly connected to the floating plate 5. The telescopic end of the No. 2 electric telescopic sleeve 61 is fixedly connected with the sealing plate 62. The sealing plate 62 is slidably and sealedly connected to the floating plate 5. The sealing plate 62 can be magnetically attracted to the electromagnet ring 9.

[0047] 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. 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.

[0048] 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;

[0049] 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 to a plurality of cutters 83, the telescopic end of the No. 3 electric telescopic sleeve 81 is elastically and slidably connected to a connecting sleeve 82, the connecting sleeve 82 is fixedly connected to an upper gear disc 85, the middle part of the floating plate 5 is fixedly connected to a lower gear 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.

[0050] 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 powered off and the suction force on the sealing plate 62 is released. At this time, the floating plate 5 falls to the water surface, and the No. 3 electric telescopic sleeve 81 is activated to extend. The No. 3 electric telescopic sleeve 81 drives the upper gear plate 85 to push the floating plate 5 into the water. At this time, the connecting sleeve 82 elastically contracts in the No. 3 electric telescopic sleeve 81, and the No. 2 electric telescopic sleeve 61 is activated to drive the sealing plate 62 to contract into the inside of the floating plate 5.

[0051] Then, the power assembly 84 is started to drive the No. 3 electric telescopic sleeve 81 to rotate. The No. 3 electric telescopic sleeve 81 drives the upper gear disc 85 to rotate. The upper gear disc 85 rotates relative to the lower gear disc 86. Under the downward thrust of the upper gear disc 85 and the upward buoyancy of the water flow on the floating plate 5, the lower gear disc 86 drives the floating plate 5 to vibrate back and forth vertically, 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 water plants and other garbage wrapped around the floating plate 5, thereby preventing the attachment of too much garbage to the floating plate 5 and affecting the monitoring results.

[0052] At this time, the No. 3 electric telescopic sleeve 81 drives the guide blade 12 to rotate, and the guide blade 12 drives the water to flow upward. The water flows through the floating plate 5 to flush the garbage remaining on the upper side of the floating plate 5. At this time, the No. 2 electric telescopic sleeve 61 is started to drive the sealing plate 62 to move back and forth in the floating plate 5. Under the guidance of the sealing plate 62, the water can continuously flush upward in different directions from the inside of the floating plate 5 to the upper side, thereby improving the flushing effect of the garbage entangled and accumulated on the upper side of the floating plate 5.

[0053] like Figure 5 As shown, as a preferred embodiment of the present invention, the power assembly 84 includes a No. 3 motor 841 and a gear transmission pair 842. The No. 3 motor 841 is fixedly connected to the strip plate 10, and a gear transmission pair 842 is provided between the No. 3 motor 841 and the No. 3 electric telescopic sleeve 81.

[0054] In this embodiment, the third motor 841 is started, and the third motor 841 drives the third electric telescopic sleeve 81 to rotate through the gear transmission pair 842.

[0055] like Figure 3 As shown in FIG. 4 , as a preferred embodiment of the present invention, the guide mechanism 4 includes a No. 1 electric telescopic sleeve 41 , a connecting plate 42 , a No. 2 motor 43 , an electric telescopic rod 44 and a guide plate 45 ;

[0056] The No. 1 electric telescopic sleeve 41 is fixedly connected to the vertical rod 1, and the telescopic end of the No. 1 electric telescopic sleeve 41 is fixedly connected to the connecting plate 42, and both ends of the connecting plate 42 are fixedly connected to the No. 2 motor 43, and the telescopic end of the No. 2 motor 43 is fixedly connected to the electric telescopic rod 44, and the electric telescopic rod 44 is fixedly connected to the guide plate 45.

[0057] In this embodiment, when the difference in water velocity between the two sides of the floating plate 5 is large, a vortex is easily generated around the floating plate 5. When the flow velocity on one side of the floating plate 5 is low, the guide plate 45 on this side of the floating plate 5 is activated to rotate, thereby increasing the flow area of the guide plate 45 on this side of the floating plate 5, reducing the flow area of the river channel on this side of the floating plate 5, and further increasing the flow velocity of the water on this side of the floating plate 5. In this way, the flow velocities of the water on both sides of the floating plate 5 are balanced.

[0058] When the cleaning mechanism 8 cleans the garbage on the floating plate 5, the two No. 2 motors 43 are started to drive the two guide plates 45 to swing back and forth synchronously. At this time, the two guide plates 45 are kept parallel. When the two guide plates 45 swing toward one side of the river channel, the guide plate 45 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 can clean up the garbage accumulated on the inner wall of the river channel. By cleaning the river channel on both sides of the floating plate 5, the accumulation of garbage in the river channel on both sides of the floating plate 5 is avoided, which may affect the stability of the water flow near the floating plate 5. The guide plate 45 away from the inner wall of the river channel guides the water flow to the floating plate 5, so that the water flow can flush the floating plate 5 from different directions.

[0059] like Figure 7 As shown, as a preferred embodiment of the present invention, a descaling component 7 is further provided on the outside of the floating plate 5, and the descaling component 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, and the scraper 72 is in contact with the outer wall of the floating plate 5.

[0060] In an embodiment of the present invention, when the water flow passes through the float 5, the water flow drives the worm gear 71 to rotate, and the worm gear 71 drives the scraper 72 to clean the attachments on the side wall of the float 5. When the worm gear 71 rotates, the worm gear 71 can push the garbage to one side and take away the garbage with the help of the thrust of the water flow, thereby ensuring the accuracy of the monitoring of the float 5.

[0061] like Figure 2 As shown in FIG. 1 , 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 ;

[0062] Both ends of the slide plate 14 and the telescopic end of the electric telescopic plate 15 are fixedly connected to elastic telescopic rods 31, and the telescopic ends of the elastic telescopic rods 31 are fixedly connected to fixed plates 32. The bottom of the fixed plates 32 is provided with a plurality of limit blocks 33, and the limit blocks 33 are rotationally connected to the fixed plates 32 through elastic torsion springs. The limit blocks 33 are tilted in the direction away from the vertical rod 1.

[0063] In this embodiment, when the slide plate 14 or the electric telescopic plate 15 drives the auxiliary limiting mechanism 3 to move to one side, the elastic telescopic rod 31 drives a row of limiting blocks 33 to move synchronously through the fixed plate 32. Under the elastic thrust of the elastic telescopic rod 31, the limiting blocks 33 are inserted obliquely downward into the bottom of the water, thereby improving the supporting and stabilizing effect of the vertical rod 1.

[0064] like Figure 2 As shown, as a preferred embodiment of the present invention, the driving assembly 2 includes a No. 1 motor 21 and a gear 22, the No. 1 motor 21 is fixedly connected to the sleeve 13, the output shaft of the No. 1 motor 21 is fixedly connected to the gear 22, and the gear 22 is engaged with the skateboard 14.

[0065] In this embodiment, the No. 1 motor 21 is started, and the No. 1 motor 21 drives the gear 22 to rotate, and the gear 22 pushes the slide plate 14 to move horizontally along the sliding sleeve 13. When the flow-facing area of the guide plate 45 on one side is larger, the No. 1 motor 21 is started at this time to drive the slide plate 14 to move to the same side, and the slide plate 14 drives the auxiliary limiting mechanism 3 to move, thereby increasing the supporting force of the guide plate 45 on this side, and avoiding rotational deviation in the water when the two guide plates 45 are subjected to inconsistent forces.

[0066] 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 the two Doppler flowmeters 11 with its preset flow velocity difference threshold. The PLC controller is electrically connected to the drive component 2, the diversion mechanism 4, the sealing mechanism 6, the cleaning mechanism 8 and the data processor.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
