Description

Technical Field

[0001] The present invention belongs to the technical field of natural disaster prevention, and in particular relates to a multifunctional natural disaster risk monitoring device and a monitoring method thereof. Background Art

[0002] Natural disasters refer to sudden, destructive and unpredictable disasters caused by the natural processes of the earth. They are usually not directly controlled by humans, but their impact can be reduced through early warning systems and emergency preparedness. Natural disasters include earthquakes, droughts, floods and forest fires. The prevention of floods mainly involves calculating and controlling rainfall, and preventive measures can be taken before floods.

[0003] Currently common rainfall measurement equipment includes water level meters, flow meters and rain gauges, which can monitor water level changes in rivers, lakes and urban drainage systems, predict flood risks and issue timely alarms. Rain gauges are divided into vibration rain gauges, pressure rain gauges, tipping bucket rain gauges and capacitive rain gauges, among which tipping bucket rain gauges are the most widely used.

[0004] Existing tipping bucket rain gauges consist of one or more tipping buckets that are designed to automatically flip over when rainwater enters. As rainwater falls on the tipping buckets, their weight gradually increases, and as the rainwater accumulates, the weight of the tipping bucket reaches a certain level, causing the tipping bucket to automatically flip over. This mechanism ensures that the tipping bucket records an event every time it collects a certain amount of precipitation, and the rainfall is determined by recording the number of times the tipping bucket flips over.

[0005] Since the bucket in the tipping bucket rain gauge is turned over by gravity, and a magnet is arranged inside the rain gauge to adsorb the bucket and ensure that the bucket can be turned over to the very end, the turning stability of the bucket is poor. Affected by the external wind force, the rain is blown onto the tipping bucket rain gauge by natural wind, which will produce a certain degree of vibration, which will have a certain impact on the turning of the bucket, causing the tipping bucket to turn over untimely. At the same time, the natural wind will blow the rain obliquely, resulting in a decrease in the funnel collection efficiency of the rainwater on the upper mobile phone of the tipping bucket rain gauge, thereby affecting the collection of rainwater and reducing the rainfall value after measurement. Therefore, the present application provides a multifunctional natural disaster risk monitoring device and a monitoring method thereof to meet the needs. Summary of the invention

[0010] Optionally, the driving structure includes a connecting block 2 fixedly mounted on the shaft rod, a telescopic rod 1 fixedly mounted on the connecting block 2, a connecting block 1 fixedly mounted on the telescopic rod 1, a rotating rod rotatably mounted on the connecting block 1, and the rotating rod is fixedly connected to the control rod.

[0011] Optionally, a section of the three-way pipe fixedly connected to the funnel is in a vertical shape, and the other two sections of the three-way pipe form an arc, and the curvature of the arc is consistent with the curvature of the water inlet hole rotating around the shaft.

[0012] Optionally, the steering mechanism includes multiple electric push rods fixedly mounted on the top of the protective tube, each of the telescopic ends of the electric push rods is rotatably mounted with a connecting block three, each of the connecting blocks three is fixedly mounted with a telescopic rod two, each of the telescopic rods two is fixedly mounted with a column, each of the columns is provided with a spherical groove, each of the spherical grooves is rollingly mounted with a ball, each of the ball rollers is fixedly mounted with a connecting rod, and multiple connecting rods are commonly fixedly mounted with a movable ring, the movable ring is connected to the funnel through a telescopic tube, a protective cover is fixedly mounted on the top of the protective tube, and a plurality of induction control structures matching the corresponding electric push rods are mounted on the upper part of the protective cover.

[0014] Optionally, the sealing mechanism comprises a support frame fixedly mounted on the tipping bucket, a bucket cover cooperating with the cavity on the tipping bucket is rotatably mounted on the support frame, and a limiting structure cooperating with the bucket cover is mounted on the bracket.

[0015] Optionally, the limiting structure comprises two fixing frames fixedly mounted on the bracket, a rotating shaft is commonly fixedly mounted on the two fixing frames, and a limiting roller cooperating with the bucket cover is rotatably mounted on the rotating shaft.

[0016] Optionally, the limiting roller consists of two sections, a straight section and an arc section, the straight section is fixedly connected to the bracket, the arc section is fixedly connected to the rotating shaft, and the curvature of the arc section is consistent with the curvature of the bucket cover rotating around the shaft.

[0017] The present invention also provides a multifunctional natural disaster risk monitoring method, comprising the following steps:

[0018] S1. When the wind blows, the steering mechanism collects rainwater in the wind direction. The collected rainwater enters the funnel and then enters the tipping bucket through the funnel, so that the water in the tipping bucket gradually increases.

[0019] S2. As the amount of rain in the bucket increases, the cavity of the bucket will be blocked by the sealing mechanism to prevent rainwater from overflowing. At this time, the amount of rainwater in the bucket is not full. When the pressure value of the pressure sensor in the bucket reaches a certain level, the pressure value can be set by the system program. The set maximum pressure value is the pressure value when the bucket cavity is just full of water.

[0020] S3. When the pressure of the pressure sensor in the tipping bucket reaches the set value, the pressure sensor will control the operation of the motor through the signal controller 1. The rotation of the motor driving end drives the shaft rod to rotate, thereby driving the tipping bucket fixedly connected to the shaft rod to rotate, pouring out the water in the tipping bucket and flowing out from the bottom of the protective tube. As the tipping bucket rotates, the two conductive sheets on the tipping bucket will intermittently touch the corresponding conductive columns, and the touch will generate an electrical signal, which will be transmitted to the indoor counting system for counting, and the rainfall is judged by counting.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above scheme, by setting up a wind direction sensor and a wind direction sensing blade, the wind direction sensing blade can be blown by natural wind, and the direction sensing blade can be rotated to a certain angle, so that the wind direction of the natural wind can be monitored. At the same time, in conjunction with a wind force sensor and a wind collecting bucket, the wind collecting bucket will rotate due to the wind force, and the wind force sensor will detect the size of the wind force through the rotation speed of the wind collecting bucket. Not only can the wind direction of the natural wind be monitored, but also the wind force of the natural wind can be monitored, with strong functionality.

[0023] By setting up signal controller one, the number of electric push rods in operation can be controlled according to the detected wind direction. At the same time, signal controller two can also control the stroke of the electric push rods according to the size of the wind force, so as to change the direction of the movable ring so that the direction of the movable ring is perpendicular to the wind direction. At this time, the efficiency of collecting rainfall can be effectively improved, thereby improving the accuracy of the measurement results during monitoring.

[0024] By setting a pressure sensor, a signal controller three and a motor, the pressure of the water in the tipping bucket can be converted into an electrical signal through the pressure sensor, and then the motor can be controlled by the signal controller three to realize the flipping of the tipping bucket. By electrically controlling the tipping bucket, the influence of natural wind carrying rainwater colliding with the protective tube and causing vibration on the rotation of the tipping bucket can be effectively avoided, ensuring that the tipping bucket flips more timely and more accurately.

[0025] When monitoring rainfall, the present invention can not only monitor wind direction and wind speed, but also use wind direction and wind speed to change the angle of a movable ring for collecting rainwater, so that the movable ring is perpendicular to the wind direction, thereby improving rainwater collection efficiency. At the same time, the tipping bucket is turned over by a motor instead of gravity, so the turning accuracy is higher and the turning is more timely, thereby making the measurement more accurate.

[0049] like Figures 1 to 6 As shown, an embodiment of the present invention provides a multifunctional natural disaster risk monitoring device, including a protective tube 1; a main body, which is installed inside the protective tube 1 and on the top of the protective tube 1, and is used to collect rainwater and measure rainwater. The main body includes a shaft 17 rotatably installed on the side wall of the protective tube 1, one end of the shaft 17 extends out of the protective tube 1, and a tipping bucket 12 is fixedly installed on the shaft 17. A bracket 9 is fixedly installed inside the protective tube 1, and two conductive columns 16 are fixedly installed on the bracket 9. Two conductive columns 16 that match the corresponding conductive columns 16 are fixedly installed on the tipping bucket 12. The protective tube 1 has a conductive sheet 19 that matches with the tipping bucket 12. A funnel 10 that matches with the tipping bucket 12 is fixedly mounted on the top of the protective tube 1. The bottom of the funnel 10 passes through the protective tube 1. The tipping bucket 12 has two water inlet holes that match with the funnel 10. A leak-proof mechanism is installed between the funnel 10 and the tipping bucket 12. During detection, the amount of rainfall is detected by calculating the frequency and number of collisions between the matching conductive sheet 19 and the conductive column 16. The more times, the higher the frequency and the greater the rainfall. The specific working of the conductive sheet 19 and the conductive column 16 is an existing technology and will not be elaborated here.

[0050] A plurality of support columns 27 are fixedly installed on the top of the protective tube 1, and a fixing ring 26 is fixedly installed on the plurality of support columns 27. The funnel 10 and the fixing ring 26 are fixedly connected, thereby supporting the funnel 10, improving the stability of the funnel 10, preventing the funnel 10 from tilting and causing the bottom of the funnel 10 to bend or break, and ensuring the water leakage efficiency of the funnel 10.

[0051] The anti-leakage mechanism includes a three-way pipe 18 fixedly installed at the bottom of the funnel 10, one end of the three-way pipe 18 is fixedly connected to the water outlet end of the funnel 10, and the other two ends of the three-way pipe 18 are respectively extended into the corresponding water inlet holes on the tipping bucket 12. A three-way valve is fixedly installed on the three-way pipe 18, and the three-way valve is controlled by the rotation of the control rod 21. A driving structure is installed between the shaft rod 17 and the control rod 21.

[0052] The three-way valve is a common fluid control valve, which is usually used to adjust the direction, flow or pressure of the fluid. It consists of a valve body, a valve core, a valve seat and a control rod 21. The opening and closing of the valve core can be changed by rotating the control rod 21, thereby realizing the flow direction change of the three-way pipe 18.

[0053] The driving structure includes a connecting block 25 fixedly mounted on the shaft 17, a telescopic rod 24 fixedly mounted on the connecting block 25, a connecting block 23 fixedly mounted on the telescopic rod 24, a rotating rod 22 rotatably mounted on the connecting block 23, and the rotating rod 22 is fixedly connected to the control rod 21.

[0054] The shaft rod 17 rotates under the drive of the motor 3, and the rotation of the shaft rod 17 drives the connecting block 25 fixedly connected thereto to rotate. The rotation of the connecting block 25 will drive the connecting block 23 to rotate through the telescopic rod 1 24. The rotation of the connecting block 23 will drive the rotating rod 22 to rotate at one end close to the connecting block 23, and the rotating rod 22 is fixedly connected to the control rod 21 at one end. Therefore, when the rotating rod 22 rotates close to one end of the connecting block 23, the rotating rod 22 will make a circular motion around the control rod 21. At this time, the circular motion made by the end of the rotating rod 22 away from the control rod 21 is not concentric with the circular motion of the connecting block 23. Therefore, when the connecting block 23 rotates, the telescopic rod 24 will be extended or compressed, so as to ensure that the moving trajectory of the connecting block 23 is consistent with the motion trajectory of the end of the rotating rod 22 away from the control rod 21.

[0055] In this way, when the outlet is changed, it can be ensured that the rainwater is always in the three-way pipe 18 to prevent the rainwater from leaking, and the probability of inaccurate monitoring caused by the loss of rainwater can be reduced to a certain extent.

[0056] The section of the tee pipe 18 fixedly connected to the funnel 10 is in a vertical shape, and the other two sections of the tee pipe 18 form an arc, and the curvature of the arc is consistent with the curvature of the water inlet hole rotating around the shaft 17. The purpose of this arrangement is to ensure that the tipping bucket 12 rotates normally and will not get stuck with the tee pipe 18.

[0057] like Figures 1 to 4 , Figures 11 to 14As shown, the protection tube 1 is equipped with a steering mechanism that matches the funnel 10. The steering mechanism includes a plurality of electric push rods 11 fixedly mounted on the top of the protection tube 1, and a connection block 3 28 is rotatably mounted on the telescopic end of each electric push rod 11, and a telescopic rod 2 29 is fixedly mounted on each connection block 3 28, and a column is fixedly mounted on each telescopic rod 29, and a spherical groove is provided on each column, and a ball 30 is rollingly mounted in each spherical groove, and a connecting rod 31 is fixedly mounted on each ball 30, and a plurality of connecting rods 31 are fixedly mounted on a plurality of connecting rods 31, and a movable ring 6 is fixedly mounted on the plurality of connecting rods 31, and the movable ring 6 is connected to the funnel 10 through a telescopic tube 7, and a protective cover 2 is fixedly mounted on the top of the protection tube 1, and a plurality of induction control structures that match the corresponding electric push rods 11 are mounted on the upper part of the protective cover 2.

[0058] As the telescopic end of the electric push rod 11 moves, the telescopic rod 29 will be driven to move. Since the movable ring 6 is driven by multiple electric push rods 11, the direction of the movable ring 6 is not toward the direction of the electric push rod 11, but it can rotate three-dimensionally within a certain angle. At this time, the connecting block 3 28 on the electric push rod 11 will rotate on the electric push rod 11, and at the same time, each telescopic rod 29 will extend to different degrees, and the ball 30 will rotate in the spherical groove.

[0059] The induction control structure includes a wind direction sensor 4 fixedly installed on the upper part of the protective cover 2, on which a wind direction sensing piece 5 is rotatably installed. The wind direction sensor 4 controls the electric push rod 11 through a second signal controller. A wind force sensor 8 is fixedly installed on the protective cover 2, on which a plurality of wind collecting buckets 32 are rotatably installed. The wind sensor 8 and the plurality of electric push rods 11 are connected in three phases through a signal controller.

[0060] By setting up a wind direction sensor 4 and a wind direction sensing blade 5, the wind direction sensing blade 5 can be blown by natural wind, and the direction sensing blade 5 can be rotated to a certain angle, so that the wind direction of the natural wind can be monitored. At the same time, in conjunction with the wind force sensor 8 and the wind collecting scoop 32, the wind collecting scoop 32 will rotate due to the wind force, and the wind force sensor 8 will detect the size of the wind force through the rotation speed of the wind collecting scoop 32. Not only can the wind direction of the natural wind be monitored, but also the wind force of the natural wind can be monitored, and the functionality is strong.

[0061] At the same time, the number of electric push rods 11 in operation can be controlled according to the detected wind direction. The stroke of the electric push rods 11 can be controlled by signal controller 2 according to the size of the wind force, so as to change the direction of the movable ring 6 so that the orientation of the movable ring 6 is perpendicular to the wind direction. At this time, the efficiency of collecting rainfall can be effectively improved, thereby improving the accuracy of the measurement results during monitoring.

[0062] like Figures 1 to 5 , Figures 7 to 10As shown, the flipping part is installed outside the protective tube 1 and inside the bucket 12, and is used for measuring the flipping of the bucket 12. The flipping part includes a motor 3 fixedly installed outside the protective tube 1, and the driving end of the motor 3 is fixedly connected to the shaft 17. The inside of the bucket 12 is divided into two cavities, and the two cavities are respectively located on both sides of the shaft 17. A pressure sensor 20 is fixedly installed in each of the two cavities. A signal controller 1 is installed between the pressure sensor 20 and the motor 3. Two sealing mechanisms that match the corresponding cavities are installed on the bucket 12. The pressure sensor 20 converts the water pressure in the bucket 12 into an electrical signal, and then the signal controller 3 controls the operation of the motor 3 to realize the flipping of the bucket 12. By electrically controlling the bucket 12, the influence of vibration caused by natural wind carrying rainwater colliding with the protective tube on the rotation of the bucket can be effectively avoided, ensuring that the bucket flips more timely.

[0063] The sealing mechanism comprises a support frame fixedly mounted on the tipping bucket 12 , on which a bucket cover 13 matching with the cavity on the tipping bucket 12 is rotatably mounted, and a limiting structure matching with the bucket cover 13 is mounted on the bracket 9 .

[0064] As the amount of water in the tipping bucket 12 increases, it may overflow, so a bucket cover 13 is used to block the tipping bucket 12. A spring coil is installed between the bucket cover 13 and the support frame to ensure that the bucket cover 13 and the tipping bucket 12 are in contact.

[0065] The limiting structure comprises two fixing frames 14 fixedly mounted on the bracket 9 , a rotating shaft is fixedly mounted on the two fixing frames 14 , and a limiting roller 15 matched with the bucket cover 13 is rotatably mounted on the rotating shaft.

[0066] As the bucket 12 rotates, the bucket cover 13 will also rotate accordingly. When the bucket cover 13 rotates to abut against the limiting roller 15, the bucket 12 continues to rotate, but the bucket cover 13 is limited by the limiting roller 15 and will not continue to rotate. At this time, the bucket 12 is opened, and the water in the bucket 12 will be poured out from the bucket.

[0067] The limiting roller 15 consists of two sections, a straight section and an arc section. The straight section is fixedly connected to the bracket 9, and the arc section is fixedly connected to the rotating shaft. The curvature of the arc section is consistent with the curvature of the bucket cover 13 rotating around the shaft 17. This ensures that the limiting roller 15 only abuts against the bucket cover 13 and does not abut against the tipping bucket 12, thereby ensuring the normal flipping of the tipping bucket 12.

[0068] The embodiment of the present invention also provides a multifunctional natural disaster risk monitoring method, and the specific operation steps are as follows:

[0069] S1. When the wind blows, the electric push rod 11 is controlled by the wind direction sensor 4 and the signal controller 1, and then the travel of each electric push rod 11 is controlled by the wind speed sensor 8 and the signal controller 2, so that the movable ring 6 is perpendicular to the wind direction. At this time, the telescopic tube 7 will be extended and retracted, and rainwater will enter the funnel 10 through the movable ring 6 and the telescopic tube 7, and then enter the tipping bucket 12 through the three-way pipe 18, so that the water in the tipping bucket 12 gradually increases.

[0070] S5. As the amount of rain in the bucket 12 increases, the bucket cover 13 will block the cavity of the bucket 12 to prevent rainwater from overflowing. At this time, the amount of rainwater in the bucket 12 is not full. After the pressure value of the pressure sensor 20 in the bucket 12 reaches a certain level, the pressure value can be set by the system program. The set maximum pressure is the pressure value when the cavity of the bucket 12 is just full of water.

[0071] S3. When the pressure of the pressure sensor 20 in the bucket 12 reaches the set value, the pressure sensor 20 will control the operation of the motor 3 through the signal controller 1. The driving end of the motor 3 rotates to drive the shaft 17 to rotate, thereby driving the bucket 12 fixedly connected to the shaft 17 to rotate, and pouring out the water in the bucket 12 and flowing out from the bottom of the protective tube 1. As the bucket 12 rotates, the two conductive sheets 19 on the bucket 12 will intermittently touch the corresponding conductive columns 16, and the touch will generate an electrical signal, which will be transmitted to the indoor counting system for counting, and the rainfall is judged by counting.

[0072] S4. As the shaft rod 17 rotates driven by the motor 3, the shaft rod 17 rotates and drives the connecting block 25 fixedly connected thereto to rotate. The rotation of the connecting block 25 will drive the connecting block 23 to rotate through the telescopic rod 1 24. The rotation of the connecting block 23 will drive the end of the rotating rod 22 close to the connecting block 23 to rotate, and the end of the rotating rod 22 close to the control rod 21 is fixedly connected to the control rod 21. Therefore, when the rotating rod 22 rotates close to the end of the connecting block 23, the rotating rod 22 will make a circular motion around the control rod 21. At this time, the circular motion of the end of the rotating rod 22 away from the control rod 21 is not concentric with the circular motion of the connecting block 23. Therefore, when the connecting block 23 rotates, the telescopic rod 24 will be driven to extend or compress, so as to ensure that the moving trajectory of the connecting block 23 is consistent with the movement trajectory of the end of the rotating rod 22 away from the control rod 21. In this way, when the outlet is changed, it can ensure that rainwater is always in the three-way pipe 18 to prevent rainwater from leaking, which can reduce the probability of inaccurate monitoring caused by rainwater loss to a certain extent.

[0073] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
