Description

Technical Field

[0001] The present invention belongs to the technical field of hydrological survey, and particularly relates to a hydrological survey device. Background Art

[0002] Hydrological survey is a key link to ensure the smooth progress of water resource management and flood control and disaster reduction work. Conducting real-time and continuous hydrological surveys on water bodies such as rivers, lakes, and reservoirs can timely grasp the changes in water conditions, and provide a basis for predicting and preventing flood disasters, as well as the rational allocation and scheduling of water resources.

[0003] Existing hydrological survey devices require operators to reach the water body site and place the survey device into the water for hydrological survey. When the water flow rate or water level of the water body changes, especially when there is heavy rain in summer, whether the survey device is washed down due to the too fast water flow rate of the water body, or the survey device is submerged due to the rising water level of the water body, it will cause serious damage to the survey device, and the operator needs to go to the site to reinstall a new survey device. The data gap caused by the damage of the survey device may lead to the failure to transmit real-time hydrological data in a timely manner, thus causing greater economic losses.

[0004] Existing hydrological survey devices consider setting a telescopic rod under the detector, and remotely controlling the telescopic rod to adjust the distance between the detector and the water body to avoid the detector being submerged when the water level of the water body rises. However, the telescopic rod can only adjust the distance between the detector and the water body. When the water flow rate of the water body is too fast, the impact of the water body on the entire survey device will still cause damage to the detector and trigger a data gap. Summary of the Invention

[0005] The purpose of the present invention is to provide a hydrological survey device that can avoid the detector being damaged and triggering a data gap when the water flow rate or water level of the water body changes.

[0014] Further, a counterweight frame is provided on the survey device. The counterweight frame is inserted into the distribution box through a plugging rod, and the distribution box is provided with a guiding hole matching the plugging rod.

[0015] Further, a stabilizing seat is provided on the outer wall of the distribution box corresponding to the guiding hole. A buffer ring is slidably arranged inside the stabilizing seat. One end of the buffer ring is lapped on the stabilizing seat through a buffer piece, and the other end of the buffer ring is connected to the outer wall of the distribution box through a buffer spring. A supporting piece matching the plugging rod is provided on the buffer piece, and the outer diameter of the buffer piece is larger than that of the supporting piece.

[0016] Further, a receiving groove is provided on the inner wall of the guiding hole. Two sealing plates are oppositely arranged in the receiving groove. Soft sheets are respectively provided at one ends of the two sealing plates close to each other. One ends of the two sealing plates far from each other are respectively connected to the inner wall of the receiving groove through a return spring; two rotating shafts are also oppositely arranged in the receiving groove. One ends of the two sealing plates far from each other are respectively connected to both sides of the stretching cover through a pull rope bypassing the rotating shaft; when the plugging rod is inserted into the distribution box through the guiding hole, it pushes open the soft sheet and moves the stretching cover, and through the pull rope, the two sealing plates are pulled away from each other, so that the soft sheet fits with the plugging rod; when the plugging rod is pulled out of the distribution box, the two sealing plates approach each other under the elastic restoring force of the return spring, so that the soft sheets fit with each other.

For example, when the data analysis finds that the water flow rate of the water body exceeds the flow rate threshold or the water level exceeds the water level threshold, the aircraft is controlled to drive the detector to fly away from the support frame. When the data analysis finds that the water flow rate of the water body returns to the normal flow rate or the water level returns to the normal water level, the aircraft is controlled to drive the detector to fly back to the support frame, and the emergency protection of the survey equipment can be completed without the operator arriving at the scene. For another example, when hydrological surveys need to be carried out on a large range of water bodies, the aircraft can be remotely controlled to drive the detector to fly to a designated position for hydrological survey work, and there is no need for the operator to arrive at the scene to arrange the equipment at multiple points, saving labor costs.

[0035] The technical solutions of the present application will be further described in detail below in combination with specific implementation manners.

[0036] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application. Without conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0037] An embodiment of the present application provides a hydrological survey device, as Figure 1 shown, including a support frame 4 and a power distribution component 3, a survey component 2 and an emergency component 1 provided on the support frame 4.

[0038] As Figure 1 and Figure 4 shown, the power distribution component 3 includes a power distribution box 31 and a photovoltaic panel provided on the support frame 4, and the photovoltaic panel is electrically connected to a power storage component in the power distribution box 31.

[0039] As Figure 1 and Figure 3As shown in the figure, the survey component 2 includes a survey device 21 disposed on the support frame 4. The survey device 21 performs hydrological surveys according to the survey control signals sent by the central station and feeds back hydrological survey data to the central station.

[0040] As Figure 1 shown in the figure, the emergency component 1 includes an aircraft connected to the survey device 21. The aircraft drives the survey device 21 to fly away from or fly back to the support frame 4 according to the emergency control signals sent by the central station and feeds back flight data to the central station.

[0041] In this embodiment, both the survey device 21 and the aircraft are charged through the power storage component in the distribution box 31.

[0042] The hydrological survey equipment provided by the embodiment of the present application can avoid data gaps caused by damage to the survey device 21 when the flow rate or water level of the water body changes by driving the survey device 21 to fly away from or fly back to the support frame 4 by the aircraft. It can not only protect the survey device 21 from damage and extend the service life of the survey device 21, but also ensure the real-time nature of hydrological survey data.

[0043] In this embodiment, both the survey device 21 and the aircraft are integrated with communication modules for data transmission with the central station.

[0044] The survey device 21 receives the survey control signals sent by the central station through the communication module and feeds back hydrological survey data to the central station; the aircraft receives the emergency control signals sent by the central station through the communication module and feeds back flight data to the central station.

[0045] The survey control signals are obtained by the central station through data analysis of the hydrological survey data fed back by the survey device 21; the emergency control signals are obtained by the central station through data analysis of the hydrological survey data fed back by the survey device 21 and the flight data fed back by the aircraft.

[0046] Specifically, the hydrological survey data includes the flow rate, water level and temperature of the water body; the flight data includes the flight altitude, flight speed, flight heading, flight attitude and flight duration of the aircraft.

[0047] The central station performs data analysis on the hydrological survey data fed back by the survey device 21 and sends survey control signals to the survey device 21, which can control the survey device 21 to perform corresponding hydrological survey work as needed, improving the efficiency of hydrological surveys.

[0048] The central station analyzes the hydrological survey data fed back by the detector 21 and the flight data fed back by the aircraft, and sends an emergency control signal to the aircraft, enabling it to timely control the aircraft to fly away from or fly back to the support frame 4 with the detector 21 according to the actual situation of the water body. For example, when the data analysis finds that the water flow velocity of the water body exceeds the velocity threshold or the water level exceeds the water level threshold, it controls the aircraft to fly away from the support frame 4 with the detector 21. When the data analysis finds that the water flow velocity of the water body returns to the normal velocity or the water level returns to the normal water level, it controls the aircraft to fly back to the support frame 4 with the detector 21, completing the emergency protection of the survey equipment without the need for the operator to reach the site. For another example, when hydrological surveys need to be carried out on a large range of water bodies, the aircraft can be remotely controlled to fly the detector 21 to a designated position for hydrological survey work, without the need for the operator to reach the site to arrange the equipment at multiple points, saving labor costs.

[0049] Based on the flight data fed back by the aircraft, the central station can timely control the start and stop of the aircraft, and timely adjust the flight altitude, flight speed, flight heading, flight attitude and flight time of the aircraft.

[0050] In a possible embodiment, as Figure 2 shown, the aircraft includes a fuselage 11, a rotating arm 12 and rotors 14.

[0051] Specifically, the rotor 14 is rotatably connected to one end of the rotating arm 12 through the drive shaft of the drive motor, and the other end of the rotating arm 12 is rotatably connected to the fuselage 11 through the adjustment shaft of the adjustment motor 13.

[0052] On the one hand, by controlling the drive shaft to rotate through the drive motor, the rotor 14 is driven to rotate at a high speed, enabling the aircraft to fly.

[0053] On the other hand, by controlling the adjustment shaft to rotate through the adjustment motor 13, the rotating arm 12 is driven to rotate relative to the fuselage 11, causing the rotating arm 12 to expand or retract relative to the fuselage 11, so as to adjust the position of the rotor 14 relative to the fuselage 11, or adjust the relative positions between the rotors 14, to achieve the adjustment of the flight pose of the aircraft.

[0054] For the hydrological survey equipment provided in this embodiment, the aircraft can adjust the position of the rotor 14 relative to the fuselage 11 or the relative positions between the rotors 14 by controlling the rotation of the rotating arm 12 through the adjustment motor 13, and can achieve the adjustment of the flight state of the aircraft.

[0055] In this embodiment, as Figure 2 shown, the top of the fuselage 11 has a structure that is high in the middle and low at the edges. The bottom of the fuselage 11 is connected to the detector 21 through a connecting block 22, and the side wall of the fuselage 11 is provided with a side wall groove for accommodating the rotating arm 12.

[0056] The hydrological survey equipment provided in this embodiment has a fuselage 11 that can shield the detector 21, preventing damage to the detector 21 caused by exposure to the sun or rain and snow. The top of the fuselage 11 has a structure that is high in the middle and low at the edges, which is conducive to the rain and snow sliding off from the edges of the fuselage 11, avoiding the accumulation of rain and snow. The rotating arm 12 can be stored in the side wall groove when not needed, saving space.

[0057] In this embodiment, as Figure 2 shown, the rotating arm 12 has a hollow structure.

[0058] The hydrological survey equipment provided in this embodiment has a hollow rotating arm 12, which can achieve the light weight of the rotating arm 12 and also avoid the accumulation of rain and snow.

[0059] In a possible embodiment, as Figure 3 shown, a counterweight frame 23 is provided on the detector 21. As Figure 4 shown, the counterweight frame 23 is inserted into the distribution box 31 through a plugging rod 25, and the distribution box 31 is provided with a guiding hole matching the plugging rod 25.

[0060] The hydrological survey equipment provided in this embodiment has the detector 21 inserted into the distribution box 31 through the plugging rod 25. When the aircraft drives the detector 21 back to the support frame 4, the plugging rod 25 can provide a guiding function for the detector 21 to fall back into the distribution box 31. When the aircraft drives the detector 21 away from the support frame 4, the counterweight frame 23 provides counterweight for the aircraft, making the flight of the aircraft more stable.

[0061] In a possible embodiment, as Figure 4 shown, a stabilizing seat 32 is provided on the outer wall of the distribution box 31 corresponding to the guiding hole. As Figure 6 shown, a buffer ring 321 is slidably arranged inside the stabilizing seat 32. One end of the buffer ring 321 is lapped on the stabilizing seat 32 through a buffer piece 323, and the other end of the buffer ring 321 is connected to the outer wall of the distribution box 31 through a buffer spring 322. A support piece 24 matching the plugging rod 25 is provided on the buffer piece 323, and the outer diameter of the buffer piece 323 is larger than the outer diameter of the support piece 24.

[0062] The hydrological survey equipment provided in this embodiment, during the process of the plugging rod 25 being inserted into the distribution box 31 through the guiding hole, the buffer ring 321 inside the stabilizing seat 32 cooperates with the buffer spring 322 and the buffer piece 323 to provide a buffering effect, which can avoid the impact on the distribution box 31 when the plugging rod 25 is inserted into the distribution box 31. After the plugging rod 25 is inserted into the distribution box 31 through the guiding hole, the counterweight frame 23 lands on the support piece 24, and the stabilizing seat 32 provides support for the counterweight frame 23.

[0063] In a possible embodiment, as Figure 4 and Figure 5As shown in the figure, a storage groove 311 is formed in the inner wall of the guiding hole. Two sealing plates 37 are oppositely arranged in the storage groove 311. Soft sheets 371 are respectively arranged at one ends of the two sealing plates 37 close to each other. One ends of the two sealing plates 37 far from each other are respectively connected with the inner wall of the storage groove 311 through return springs 38. Two rotating shafts 36 are also oppositely arranged in the storage groove 311. One ends of the two sealing plates 37 far from each other are respectively connected to two sides of the stretching cover 34 through pull ropes 35 bypassing the rotating shafts 36. When the inserting rod 25 is inserted into the distribution box 31 through the guiding hole, it pushes open the soft sheet 371 and drives the stretching cover 34 to move. The two sealing plates 37 are driven to move away from each other through the pull ropes 35, so that the soft sheet 371 fits against the inserting rod 25. When the inserting rod 25 is pulled out of the distribution box 31, the two sealing plates 37 move close to each other under the action of the elastic restoring force of the return spring 38, so that the soft sheets 371 fit against each other.

[0064] Specifically, when the inserting rod 25 is not inserted into the distribution box 31, the return spring 38 is in its initial state. At this time, the two soft sheets 371 fit against each other, which can seal the interior of the distribution box 31 and prevent rain, snow or other impurities from passing through the guiding hole and falling into the distribution box 31. When the inserting rod 25 is inserted into the distribution box 31 through the guiding hole, the inserting rod 25 first pushes open the two soft sheets 371 that fit against each other, then abuts against the stretching cover 34 and drives the stretching cover 34 to move. The stretching cover 34 drives the two sealing plates 37 to move away from each other through the pull ropes 35, so that the two soft sheets 371 also move away from each other and fit against the side wall of the inserting rod 25. This can still seal the interior of the distribution box 31 and can scrape rain, snow or other impurities on the side wall of the inserting rod 25 during the insertion process of the inserting rod 25, preventing the interior of the distribution box 31 from getting wet or polluted due to the insertion of the inserting rod 25. At this time, the return spring 38 is in a compressed state. When the inserting rod 25 is pulled out of the distribution box 31, the two sealing plates 37 move close to each other under the action of the elastic restoring force of the return spring 38, so that the two soft sheets 371 also move close to each other and finally return to the initial fitting state, sealing the interior of the distribution box 31 again. At this time, the stretching cover 34 also moves to the initial position through the pull ropes 35 during the process of the two sealing plates 37 moving close to each other.

[0065] For the hydrographic survey equipment provided in this embodiment, on the one hand, the stretching cover 34 and the return spring 38 cooperate with the sealing plates 37 and the soft sheets 371 to seal the interior of the distribution box 31, preventing rain, snow or other impurities from falling into the distribution box 31. On the other hand, the stretching cover 34 and the return spring 38 play a buffering role for the inserting rod 25, slowing down the speed when the inserting rod 25 is inserted into the distribution box 31 and reducing the impact on the distribution box 31 when the inserting rod 25 is inserted into the distribution box 31.

[0066] In a possible embodiment, the soft sheet 371 is a flexible polymer sheet or an elastic silicone sheet.

[0067] Specifically, the soft sheet 371 is a sheet material made of silicone, with a thickness of 0.5 mm to 2 mm, a Shore A hardness of 30 to 50, and a tensile strength greater than or equal to 5 MPa.

[0068] In one possible embodiment, a charging ring 33 is provided in the guide hole corresponding to the inner wall of the distribution box 31, and a charging component matching the charging ring 33 is provided at one end of the plug-in rod 25 inserted into the distribution box 31. The surveyor 21 and the aircraft are both charged by docking with the charging ring 33 through the charging component on the plug-in rod 25.

[0069] Specifically, when the plug-in rod 25 is inserted into the distribution box 31, the charging part on the plug-in rod 25 docks with the charging ring 33, and the surveyor 21 is charged through the plug-in rod 25 and the counterweight frame 23, and the aircraft is charged through the plug-in rod 25, the counterweight frame 23, the surveyor 21 and the connecting block 22.

[0070] In a possible embodiment, after the aircraft drives the surveyor 21 away from the support frame 4, it can fly to a preset charging position for charging according to the emergency control signal sent by the central station.

[0071] In this embodiment, the preset charging position is also provided with a charging ring 33 that matches the charging component on the plug-in rod 25.

[0072] In one possible embodiment, Figure 7 As shown, the end of the plug rod 25 inserted into the distribution box 31 is tapered.

[0073] In this embodiment, Figure 4 As shown, the stretch cap 34 is conical and matches the plug-in rod 25 .

[0074] In the hydrological survey equipment provided in this embodiment, the end of the plug-in rod 25 inserted into the distribution box 31 is tapered, which can facilitate the smooth insertion of the plug-in rod 25 into the distribution box 31 and ensure that the charging part on the surveyor 21 is accurately connected with the charging ring 33.

[0075] In a possible embodiment, the surveyor 21 is integrated with a laser displacement sensor, a displacement monitor, and a tilt sensor.

[0076] In this embodiment, the laser displacement sensor uses the reflection principle of a laser beam to measure the distance between the surveyor 21 and the water body. The displacement monitor can measure the displacement changes of the water body through positioning technology. The tilt sensor is used to measure the tilt angle of the water level to determine whether the water level is stable.

[0077] In a possible embodiment, a temperature sensor is also integrated into the surveyor.

[0078] In this embodiment, the temperature sensor is used to measure the temperature of the water body.

[0079] The embodiment of the present application provides a data aggregation and processing method, which is applicable to the hydrological survey equipment provided in any embodiment of the present application. This method uses a data aggregation and processing system for data aggregation and processing. The data aggregation and processing system includes a front-end perception facility, a data transmission network, a back-end data processing center, and a visualization display platform; among which, the front-end perception facility includes a laser displacement sensor, a GPS displacement monitor, and an inclination sensor; the data transmission network includes a data acquisition end, a network transmission end, and a management center end; the specific steps are as follows:

[0080] Step 1: The laser displacement sensor uses the reflection principle of the laser beam to measure the distance;

[0081] The GPS displacement monitor can measure the displacement change of the water level through GPS technology;

[0082] The inclination sensor is used to measure the inclination angle of the water level and judge whether the water level is in a stable state;

[0083] Step 2: The data acquisition end is used to collect the data of the laser displacement sensor, the GPS displacement monitor, and the inclination sensor, and through the network transmission end, using 4G / 5G networks and industrial-grade wireless router devices, to achieve fast and stable data transmission;

[0084] Step 3: The visualization display platform receives the transmission data from the front-end perception facility through the server, performs real-time analysis and processing, and deploys monitoring software through the cloud assistant to achieve real-time dynamic visualization display.

[0085] 4G / 5G networks have the characteristics of wide coverage, fast transmission speed, and good stability. In the case of good network coverage on the lake surface, the wireless cellular network is the preferred method for data transmission. In the case of poor network coverage on the lake surface or inability to access the wired network, satellite communication can be used as an alternative data transmission solution. Satellite communication has the characteristics of being unrestricted by geography and having a long transmission distance, but the cost is relatively high. For example, fiber optic networks, Ethernet, etc., have the advantages of fast transmission speed and good stability. However, under the complex terrain and geological conditions of the lake surface, the laying and maintenance of wired networks may face greater difficulties. For example, the Beidou satellite navigation system, private network radio, etc., these communication methods usually have higher security and stability and are suitable for scenarios with high requirements for data transmission security.

[0086] After the data is collected, the detector 21 is taken to a preset position by the aircraft for charging.

[0087] The data aggregation and processing method provided by the embodiment of the present application has the corresponding beneficial effects of the hydrological survey equipment.

[0088] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present application.
