Description

Technical Field

[0001] The present invention relates to the technical field of flood prevention and early warning equipment, and in particular to a river flood early warning device. Background Art

[0002] Currently, the commonly known flood prevention method is to increase flood discharge capacity. Common measures include building river embankments and regulating river channels. Before the flood arrives, using flood warning devices to detect floods is also an indispensable defense measure.

[0003] Existing flood warning methods usually monitor the water level of the river, usually through water level monitoring or flow monitoring. When the water level monitor detects that the water level has reached the warning line, the alarm will start to sound. Due to the high installation cost of this warning method, the warning device is usually only placed in upstream areas such as reservoirs and dams. The upstream monitoring results can provide more response time for downstream residents. However, due to the lack of early warning measures downstream, downstream residents also need a certain amount of evacuation time when they receive the warning information sent from upstream. If the flood is too large and too fast, the downstream area also lacks certain protective measures.

[0004] In order to solve the above problems, a river flood warning device for downstream is proposed. Summary of the Invention

[0005] In response to the above-mentioned problems, the present invention provides a river flood warning device, which solves the problem that traditional warning methods usually only place warning devices in upstream areas such as reservoirs and dams due to the high installation cost.

[0111] In order to make the purpose, technical solutions and advantages of the invention more clearly understood, the present invention is 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.

[0113] refer to Figures 1 to 15 A river flood warning device includes an L-shaped mounting plate 10, a waterproof box 15, a horizontal mounting plate 21, a mounting frame 7, a guardrail 13, a vertical mounting plate 12, a warning light 1201, a flow rate monitoring fan 26, a water level monitoring mechanism, a transmission mechanism, an alarm mechanism, a first sliding mechanism, a second sliding mechanism, and a third sliding mechanism;

[0114] The two sides of the waterproof box 15 are respectively fixed with the horizontal plates of the L-shaped mounting plate 10. The ends of the horizontal plates of the two L-shaped mounting plates 10 are respectively fixed on the two side walls of the waterproof box 15. The waterproof box 15 can prevent external water from entering the box body. The L-shaped mounting plate 10 is used to fix the waterproof box 15;

[0115] The outer walls of the vertical plates of the two L-shaped mounting plates 10 are respectively fixedly connected to the river bank wall 101 to be installed;

[0116] A first gap is left between the bottom wall of the waterproof box 15 and the upper end of the riverbed 1, and its function is to facilitate water flow through the first gap;

[0117] A horizontal mounting plate 21 is fixedly mounted on the lower side of the front wall of the waterproof box 15. The horizontal mounting plate 21 is used to mount the transmission mechanism described later.

[0118] The upper ends of the horizontal mounting plate 21 are fixedly mounted with mounting frames 7 on both sides. A second gap is left between the two mounting frames 7 and the riverbank walls 101 to be mounted on both sides. The two mounting frames 7 are used to fix the moving track of the transmission mechanism.

[0119] The same water level monitoring mechanism is installed on the outside of the two installation frames 7, which is used to monitor the river water level in real time and provide feedback;

[0120] A transmission mechanism is movably mounted on the upper end of the horizontal mounting plate 21, and the transmission mechanism is movably arranged between the two mounting frames 7;

[0121] The transmission mechanism is driven by the water level monitoring mechanism to work. During the operation of the water level monitoring mechanism, the second sliding mechanism described later is driven to work through the transmission mechanism.

[0122] An alarm mechanism is installed in the waterproof box 15, and the alarm mechanism is driven to work by the second sliding mechanism;

[0123] Flow rate monitoring fans 26 are movably mounted on the outer sides of the two mounting frames 7. Both flow rate monitoring fans 26 are driven to slide by a first sliding mechanism, which is driven to work by a transmission mechanism. When the water level of the river rises, the two flow rate monitoring fans 26 will slide outwards driven by the first sliding mechanism and begin to rotate under the impact of the water flow. The greater the flow rate of the water flow, the faster the rotation speed of the flow rate monitoring fans 26. The alarm mechanism described later will have different levels of alarm effects according to the different rotation speeds of the flow rate monitoring fans 26.

[0124] A sealing cover 16 is detachably mounted on the upper end of the waterproof box 15. A vertical mounting plate 12 is movably mounted above the sealing cover 16. The vertical mounting plate 12 is driven to slide by a second sliding mechanism, which is driven by a transmission mechanism. The sealing cover 16 is used to prevent water from entering the interior of the waterproof box 15 from the upper end and thereby damaging the alarm device.

[0125] A plurality of warning lights 1201 are mounted on the vertical mounting plate 12, and the warning lights 1201 are electrically connected to the two flow rate monitoring fans 26 respectively;

[0126] A plurality of protection bars 13 are movably mounted on the inner walls of the horizontal plate and the vertical plate of the two L-shaped mounting plates 10 . The plurality of protection bars 13 are driven to slide by a third sliding mechanism, and the third sliding mechanism is driven to work by the second sliding mechanism.

[0127] The water level monitoring mechanism comprises a first connecting rod 4, a floating body 3, and a main shaft 31;

[0128] A main shaft 31 is rotatably installed on the side wall of the horizontal mounting plate 21;

[0130] The front ends of the two first connecting rods 4 are respectively installed with floating bodies 3, and the two floating bodies 3 are respectively arranged in the two second gaps;

[0131] The main shaft 31 drives the transmission mechanism to work by rotating. When the water gradually rises, the two floats 3 will slowly rise along with the water level line. During the process of the two floats 3 being lifted up, the two first connecting rods 4 connected to the two floats 3 will begin to rotate upward. During the process of the two first connecting rods 4 being lifted up, the two first connecting rods 4 will begin to rotate around their rotation centers. Since the main shaft 31 fixes the rotation centers of the two first connecting rods 4 together, the main shaft 31 begins to rotate synchronously with the two first connecting rods 4. During the rotation, the main shaft 31 will drive the alarm mechanism through the transmission mechanism, thereby realizing water level monitoring and early warning.

When the water level rises, the reference Figure 1, the rack plate 2 starts to slide backward, and in the process of sliding backward, the rack plate 2 drives the transmission plate 6 fixed thereto to start sliding backward. In the process of sliding backward, the transmission plate 6 drives the first rectangular blocks 20 on both sides to start sliding backward. The sliding tracks of the two first rectangular blocks 20 are limited by the mounting frames 7 on both sides. In the process of sliding backward, the two first rectangular blocks 20 respectively drive the first sliding mechanism, the second sliding mechanism and the alarm mechanism described later to start working.

[0170] Positive electrode blocks 1901 are respectively mounted on the inner walls of the two second slide bars 19, and the front walls of the two positive electrode blocks 1901 are respectively in detachable contact with the inner side of the front wall of the waterproof box 15;

[0171] Negative electrode blocks 1502 are installed on both sides of the rear wall of the waterproof box 15, and the two positive electrode blocks 1901 are in detachable contact with the two negative electrode blocks 1502;

[0172] One side of the two negative electrode blocks 1502 is electrically connected to a control board, which is electrically connected to the two flow rate monitoring fans 26 through a plurality of first wires.

[0173] The upper end of the sealing cover 16 is fixedly mounted with the fixed ends of several waterproof telescopic barrels 28, and the fixed ends of the several waterproof telescopic barrels 28 are respectively connected to the sealing cover 16;

[0174] The movable ends of the plurality of waterproof telescopic barrels 28 are respectively fixedly connected to the lower ends of the vertical mounting plates 12;

[0175] The control panel is electrically connected to the warning lights 1201 through the second wires. The second wires are respectively connected to the waterproof telescopic barrels 28. The two second rectangular blocks 18 respectively drive the second slide bars 19 fixed thereto to start sliding backwards during the backward sliding process. The two second slide bars 19 will slide through the two mounting frames 7 and the waterproof box 15 in a sealed manner during the backward sliding process and enter the interior of the waterproof box 15. Figure 4As the two second slide bars 19 slide, the positive electrode block 1901 fixedly connected to the second slide bar 19 also begins to slide backward with the second slide bar 19. There are second rectangular through grooves 1501 on the two inner side walls of the waterproof box 15, which provide sliding tracks for the two positive electrode blocks 1901 and enable them to be exposed. As the two positive electrode blocks 1901 slide backward, they touch the negative electrode block 1502, thereby energizing the control board. A flow rate sensor is installed inside the control board, which can convert the rotation speed of the two flow rate monitoring fans 26 into electrical signals. This is prior art and will not be described in detail here. The flow rate monitoring fan 26 begins to rotate with the water flow. When the flow rate is between 2m / s and 4m / s, the first warning light 1201 starts to turn on. When the flow rate is between 4m / s and 8m / s, the second warning light 1201 starts to light up. When the flow rate is above 8m / s, the third warning light 1201 lights up. Users are not limited to the above-mentioned monitoring intervals and can set alarm intervals according to specific circumstances. The two second rectangular blocks 18 also drive the second connecting rods 8 to start deflecting upward while sliding backward. In the process of upward deflection, the two second connecting rods 8 also drive the two first mounting frames 1101 to start sliding upward. The two first sliding bars 11 fixedly installed with the two first mounting frames 1101 now drive the vertical mounting plate 12 to start sliding upward. In the process of the vertical mounting plate 12 sliding upward, the waterproof telescopic barrel 28 begins to extend upward.

[0176] The third sliding mechanism includes a first linkage shaft 32, a second linkage shaft 29, and a coupling member 30;

[0177] The upper ends of the vertical plates of the two L-shaped mounting plates 10 are respectively provided with a plurality of second rectangular through holes 1003 , and the plurality of protection rails 13 are respectively slidably arranged in the plurality of second rectangular through holes 1003 ;

[0178] The inner walls of the vertical plates of the two L-shaped mounting plates 10 are respectively provided with third rectangular through slots 1002 that cooperate with the second rectangular through holes 1003. The third rectangular through slots 1002 are connected to the second rectangular through holes 1003 that cooperate with them.

[0179] Second mounting brackets 1301 are respectively installed on the inner walls of the plurality of protection fences 13;

[0180] The same second linkage shaft 29 is installed through the plurality of second mounting brackets 1301 located on the vertical plate of the same L-shaped mounting bracket 10;

[0181] The same first linkage shaft 32 is installed through the plurality of first mounting brackets 1101 located on the horizontal plate of the same L-shaped mounting bracket 10;

[0182] The first linkage shaft 32 and the second linkage shaft 29 on the same side are fixedly connected by a coupling 30;

[0183] The outer sides of the plurality of protection fences 13 are respectively slidably sleeved with expansion protection fences 14;

[0184] A plurality of expansion protection rails 14 are respectively connected to the upper ends of the vertical plates of the adjacent L-shaped mounting frames 10 via return springs 24;

[0185] When the two first mounting frames 1101 start to move upward, they will start to move upward through the two first linkage shafts 32 respectively, and the several first mounting frames 1101 connected to the first linkage shafts 32 on both sides will be lifted upward. At the same time, when the first linkage shaft is lifted upward, it will drive the second linkage shafts 29 on both sides to be lifted upward through the connecting shafts 30 on both sides. At this time, the several second mounting frames 1301 connected to the two second linkage shafts 29 also drive the guardrail 13 to be lifted upward to achieve the protection function. It should be noted that when the guardrail 13 is lifted upward, the expanded guardrail 14 cooperating with it will also be lifted upward. When the expanded guardrail 14 is lifted upward, it begins to stretch the reset spring 24. At this time, the resetting force of the reset spring 24 is less than the buoyancy of the float 3. When the water level drops, the reset spring 24 begins to reset and presses the guardrail 13 downward through the expanded guardrail 14, which can quickly reset the float 3.

[0186] Alarms are installed in each of the warning lights 1201, and the alarms are electrically connected to the control panel through wires. The purpose is that when the warning lights 1201 light up, the alarms can sound accordingly. The more the warning lights 1201 light up, the louder the alarm sounds, thereby serving as a warning.

[0187] Implementation method of the present invention:

[0188] Install the two L-shaped mounting plates 10 of the device on both sides of the river bank. Users can choose the appropriate L-shaped mounting plate according to the width between the two sides of the river bank to ensure that the waterproof box 15 can be located in the central area of ​​the river for more accurate monitoring.

[0189] After the equipment is installed, the floats 3 on both sides are located on the water level line. Before a flood comes, the water level will rise accordingly. The floats 3 on both sides will also slowly rise up with the rising water level, and in the process of rising, the main shaft 31 will start to rotate. The main shaft 31 will drive the transmission plate 6 to slide backward during the rotation. The transmission plate 6 will drive the second slide bars 19 on both sides to slide inside the waterproof box 15 during the backward sliding process. The two second slide bars 19 will make the positive electrode block 1901 and the negative electrode block 1502 contact during the sliding process, so that the control board is energized and works.

[0190] When the control panel is powered on, the guardrails 13 on both sides of the river bank rise upwards to protect pedestrians on both sides of the river bank, and the two expansion mounting plates 25 drive the flow rate monitoring fan 26 to extend outwards to contact the river;

[0191] Before a flood comes, the flow rate of the water will gradually increase. The rotation speed of the two flow rate monitoring fans 26 will increase as the speed of the water flow increases, and the rotation speed of the monitoring fans will be transmitted to the upward-raised warning lights 1201 through the control panel. The warning lights 1201 will light up in sequence with the speed range of the monitoring fans. When the warning lights 1201 light up, the alarm inside them will also sound. The more warning lights 1201 light up, the louder the alarm will be, thereby serving as an early warning.

[0192] The water level detection mechanism of the present invention can detect and warn the river water level in real time, the alarm mechanism of the present invention can effectively monitor and alarm the water flow velocity, and the guardrail of the present invention can slide back and forth under the drive of the third sliding mechanism. When the water level rises, the guardrail is raised to effectively play a protective role.

[0193] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
