Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to a water level monitoring device for collecting hydrological data based on water conservancy engineering design. Background Art

[0002] The water level monitoring device for hydrological data collection designed based on water conservancy projects is a device specially used to monitor water level changes and collect hydrological data. The device is used in water conservancy projects to monitor water level changes to collect hydrological data. It is mainly composed of radar or ultrasonic sensors, data acquisition and transmission modules and power supply systems. It has high-precision, all-weather, real-time remote monitoring functions and is widely used in reservoirs, rivers and urban flood control management to improve the efficiency and safety of water conservancy projects.

[0003] A water level monitoring device is disclosed in the patent publication number CN118548961A, including a liquid level detector and a water depth detector, wherein the liquid level detector is installed at the end of a horizontally extended crossbar, the crossbar is arranged at the top of a column, the bottom of the column is fixedly installed at the bottom of the water body, a floating platform is slidably installed on the column through a limit device, the detection head of the liquid level detector is vertically downwardly aligned with the upper surface of the floating platform, a floating block is fixedly installed at the bottom of the floating platform, a submersible mounting seat extending vertically downward is arranged on the floating platform, the water depth detector is installed in the submersible mounting seat, and the depth detector extends into the water body. The present invention can realize the accurate measurement of the liquid level and the distance from the liquid level to the bottom of the water body, so as to fully reflect the changes of the water body and timely discover the changes of the bottom of the water body.

[0004] The prior art has the following defects:

[0005] Existing radar monitoring will be interfered by the environment and reflection characteristics: when the radar monitors the water surface, it will be affected by the waves and foam on the river surface, resulting in data fluctuations, and the radar waves need a good reflecting surface. If there are a large number of floating objects or foreign objects covering the water surface, the reflection quality of the signal may decrease, resulting in measurement errors. Therefore, it is necessary to set up a device that can reduce the fluctuations of the detected water surface to prevent floating objects and foreign objects from entering the detected water surface, so as to improve the reliability and accuracy of water level monitoring.

[0006] Existing radar monitoring cannot cope well with extreme weather: extreme weather (such as heavy rain, strong winds, and lightning) will cause the radar to be unable to obtain reflected signals, resulting in data transmission interruption or omission, which will increase the deviation of the measurement results and make it difficult to reflect the true water level. In addition, under extreme weather conditions, the environmental noise will increase, making it difficult to distinguish the signal, affecting the measurement accuracy. Therefore, it is necessary to set up a mechanical monitoring device to continue to provide data support when the radar signal is interfered with or interrupted, so as to improve the reliability and stability of the overall system. Summary of the invention

[0045] Example 1, reference Figure 1 - Fig.10 , which is the first embodiment of the present invention, provides a water level monitoring device for collecting hydrological data based on water conservancy engineering design, including a base 1, a vertical support assembly 2 and a lifting assembly 4 arranged above the base 1, a transverse support mechanism 3 arranged above the lifting assembly 4, and a floating mechanism 5 arranged below the transverse support mechanism 3, the base 1 is arranged on the shore ground, the floating mechanism 5 is arranged on the water surface, the vertical support assembly 2 includes a vertical support rod 21 fixedly installed on the top of the base 1, the transverse support mechanism 3 includes a transverse support rod 31 installed on the outer wall of the vertical support rod 21, a plurality of steering balls 34 are movably connected between the inner wall of the transverse support rod 31 and the outer wall of the vertical support rod 21, a control box 35 and a plurality of claw hooks 32 are fixedly connected to the bottom of the transverse support rod 31, and the plurality of claw hooks 32 are all arranged above the lifting assembly 4.

[0046] Reference Figure 3 - Figure 5 The lifting assembly 4 includes a support plate 41 fixedly installed on the top of the base 1, a lifting seat 42 is fixedly connected to the top of the support plate 41, and a plurality of lifting columns 45 are movably connected to the inner wall of the lifting seat 42. The inner walls of the plurality of lifting columns 45 are all provided with claw grooves 49, and the plurality of claw grooves 49 are respectively engaged with the plurality of claw hooks 32.

[0047] Specifically, the base 1 and the vertical support assembly 2 form a basic radar monitoring device. In order to avoid the influence of waves and foam on the river surface when monitoring the water surface, resulting in data fluctuations, and a large number of floating objects or foreign objects covering the water surface, resulting in a decrease in the reflection quality of the signal and causing measurement errors, a transverse support mechanism 3 is set on the vertical support assembly 2, and a floating mechanism 5 is set at one end of the transverse support mechanism 3 and placed in water to prevent floating objects and foreign objects from entering the detection water surface, so as to make the detection more accurate; in order to avoid affecting the measurement accuracy under extreme weather conditions, the floating mechanism 5 will be driven to rise when the water level rises, and then the transverse support rod 31 will be raised by the lifting assembly 4 to read the rising distance in a mechanical form, so as to continue to provide data support when the radar signal is interfered or interrupted.

[0048] By installing the steering ball 34 on the vertical support rod 21, sleeve the transverse support rod 31 on the outer periphery of the steering ball 34, move the transverse support rod 31 downward to a suitable position, then fix the base 1 on the river bank, install the vertical support rod 21 and the support plate 41 on the base 1, rotate the lifting column 45 in the lifting seat 42, corresponding to the claw groove 49 and the claw hook 32, move the transverse support rod 31 downward, make the claw hook 32 snap into the claw groove 49, and complete the docking.

[0049] Reference Figure 3 - Figure 5 The bottom of the lifting column 45 is rotatably connected to a fixed plate 44, a pressure spring 43 is fixedly connected between the bottom of the fixed plate 44 and the inner wall of the lifting seat 42, the outer wall of the lifting column 45 is fixedly connected to a rotating rod 46, the outer wall of the lifting seat 42 is provided with a lifting groove 48, the inner wall of the lifting groove 48 is movably connected to the outer wall of the rotating rod 46, and a rotating wheel 47 is fixedly connected between the outer walls of multiple rotating rods 46.

[0050] Specifically, the pressure spring 43 provides an upward rebound force after being pressed downward. When the transverse support rod 31 is in balance, the pressure spring 43 does not rebound under the pressure. When the transverse support rod 31 rises, the pressure spring 43 unloads the force and rises.

[0051] By pulling down the rotating wheel 47, the rotating rod 46 is driven to be placed at the lower end of the lifting groove 48, and the lifting column 45 is then pressed down by the pressure spring 43 through the fixed plate 44 and placed inside the lifting seat 42. The rotating wheel 47 is operated to rotate to limit the movement of the lifting column 45. If the water level rises, the transverse support rod 31 rises accordingly, and the lifting column 45 moves upward in the lifting groove 48 under the unloading force of the pressure spring 43.

[0052] Reference Figure 6 - Fig. 9 The lateral support mechanism 3 also includes a power assembly 33 installed inside the lateral support rod 31. The power assembly 33 includes a power output device 331 fixedly connected to the bottom of the lateral support rod 31. The output shaft of the power output device 331 is fixedly connected to a transmission gear 332. The inner wall of the lateral support rod 31 is rotatably connected to a plurality of driven gears 334. A special-shaped transmission belt 333 is transmission-connected between the plurality of driven gears 334 and the transmission gear 332.

[0053] By starting the power output device 331 , the output shaft of the power output device 331 drives the plurality of driven gears 334 to rotate through the transmission gear 332 and the special-shaped transmission belt 333 , thereby providing power for the floating mechanism 5 to rise and fall.

[0055] Specifically, the floating barrels 522 are distributed in a circular shape inside the floating frame 521, so that the floating frame 521 floats on the water in a balanced manner. The foreign object blocking bar 523 can prevent foreign objects from entering the gap between the floating barrels 522 and the detection water surface in the center of the floating frame 521. The sinking bin 53 has a filtering effect to prevent foreign objects from entering the detection water surface, and the water in the sinking bin 53 is always flowing, which can make the water level of the detection water surface level with the surrounding water level, making the monitoring more accurate.

[0056] By lowering the floating frame 521 onto the water surface and placing the sinking bin 53 into the water, a detection water surface is formed at the center of the floating frame 521. The floating barrel 522 inside the lowered floating frame 521 can provide buoyancy, and the external foreign object barrier 523 can prevent foreign objects from entering the detection water surface. The sinking bin 53 filters and enters the water to provide pressure, so that the entire transverse support rod 31 is balanced.

[0057] During use, the steering ball 34 is installed on the vertical support rod 21, and the transverse support rod 31 is sleeved on the outer periphery of the steering ball 34. The transverse support rod 31 is moved down to a suitable position, and then the base 1 is fixed on the river bank ground, and the vertical support rod 21 and the support plate 41 are installed on the base 1. The rotating wheel 47 is pulled down to drive the rotating rod 46 to be placed at the lowest end of the lifting groove 48. The lifting column 45 is then pressed down by the pressure spring 43 through the fixing plate 44 and placed inside the lifting seat 42. The rotating wheel 47 is operated to rotate to limit the movement of the lifting column 45. At this time, the lifting column 4 The claw groove 49 opened on the upper side corresponds to the claw hook 32, the horizontal support rod 31 is moved downward, the claw hook 32 is clamped into the claw groove 49, and the docking is completed. Then the power output device 331 is started, and the output shaft of the power output device 331 drives the multiple driven gears 334 to rotate through the transmission gear 332 and the special-shaped transmission belt 333, so that the multiple threaded rods 51 move in the multiple driven gears 334, the floating frame 521 is lowered and placed on the water surface, the sinking chamber 53 is placed in the water, the center of the floating frame 521 forms a detection water surface, and the inside of the floating frame 521 is lowered The floating barrel 522 can provide buoyancy, the external foreign body barrier 523 can prevent foreign bodies from entering the detection water surface, the sinking bin 53 filters and enters the water to provide pressure, so that the entire transverse support rod 31 is balanced, and the rotating wheel 47 is operated again to rotate, so that the rotating rod 46 is disengaged, the claw hook 32 is buckled, and the lifting column 45 can move in the lifting groove 48 as the water level rises, and the installation is completed, so as to achieve the effect of improving the reliability and accuracy of water level monitoring. During monitoring, the radar monitor on the radar monitoring frame 27 monitors the detection water surface, and the control box 35 transmits the signal to Remote terminal to achieve water level monitoring effect; when encountering extreme weather, the radar signal is interfered with. At this time, if the water level rises, the floating frame 521 will rise accordingly, and the lifting column 45 will move upward in the lifting groove 48 under the unloading force of the pressure spring 43, and the limit rod 364 will move upward together. The water level rising distance can be judged by the rising distance of the limit rod 364 through the camera probe on the radar monitoring frame 27 or on-site exploration. In this way, data support can continue to be provided when the radar signal is interfered with or interrupted, thereby achieving the effect of improving the reliability and stability of the overall system.

[0058] Example 2, reference Fig.11 - Fig.13 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: Fig.12The outer wall of the vertical support rod 21 is provided with a plurality of mounting holes 22, and the inner wall of the mounting hole 22 is fixedly installed with a mounting bracket 23.

The limit assembly 36 includes a connecting rod 361 hinged to one of the mounting brackets 23, and the inner wall of the connecting rod 361 is provided with a trip groove 362. The inner wall of the trip groove 362 is slidably connected to the limit claw 363. A limit rod 364 is slidably connected between one end of the connecting rod 361 and the outer wall of the limit claw 363, and the bottom of the limit rod 364 is fixedly connected to the top of the transverse support rod 31.

[0059] Specifically, the radar monitoring frame 27 is provided with a radar monitor and a monitoring probe for radar monitoring and visual monitoring of the water level. The solar panel 24 provides power for the entire device. Multiple mounting holes 22 can adjust the position of each device. The mounting holes 22 are arranged to be compatible with the mounting frame 23 to achieve the effect of convenient installation. When the limit claw 363 clamps the limit rod 364, the shaking of the lateral support rod 31 can be avoided. When the limit claw 363 retracts into the release groove 362, the limit rod 364 can be separated from the connecting rod 361.

[0060] By installing several mounting frames 23 at the mounting holes 22 of the vertical support rods 21, and installing solar panels 24, radar monitoring frames 27 and connecting rods 361 on the several mounting frames 23 respectively, a modular assembly effect is achieved, and the limiting claws 363 are released from the release grooves 362 to make the limiting rods 364 leave the connecting rods 361, and the limiting rods 364 can be used to pull the transverse support rods 31 for steering, so that the floating mechanism 5 is moved to the shore for easy maintenance and installation.

[0061] Reference Fig.13 A ball mounting groove 25 is also provided on the outer wall of the vertical support rod 21 , and a lightning rod 26 is installed on the top of the vertical support rod 21 .

[0062] Specifically, the ball mounting groove 25 can facilitate the installation and removal of the steering ball 34, and the lightning rod 26 can play a lightning protection effect, reducing the impact of lightning on the radar.

[0063] During use, the steering ball 34 is installed at the ball installation groove 25 above the vertical support rod 21 to facilitate the installation and removal of the steering ball 34, and several mounting frames 23 are installed at the mounting hole 22 of the vertical support rod 21. The solar panel 24, the radar monitoring frame 27 and the connecting rod 361 are respectively installed on the several mounting frames 23 to achieve the effect of modular assembly, and the limiting claw 363 is released in the release groove 362 to make the limiting rod 364 leave the connecting rod 361, and the limiting rod 364 can be used to pull the transverse support rod 31 for steering, so that the floating mechanism 5 is moved to the shore for easy maintenance and installation. The rest of the structure is the same as that of Example 1.

[0064] Working principle of the present invention:

[0065] During installation, the steering ball 34 is installed at the ball installation groove 25 above the vertical support rod 21, and the transverse support rod 31 is sleeved on the outer periphery of the steering ball 34. The transverse support rod 31 is moved down to a suitable position, and then several mounting frames 23 are installed at the mounting holes 22 of the vertical support rod 21. The solar panels 24, the radar monitoring frames 27 and the connecting rods 361 are respectively installed on the several mounting frames 23. Then, the base 1 is fixed on the river bank ground, and the vertical support rods 21 and the support plates 41 are installed on the base 1.

[0066] Pulling down the rotating wheel 47 drives the rotating rod 46 to be placed at the lower end of the lifting groove 48, and the lifting column 45 then presses down the pressure spring 43 through the fixed plate 44 and is placed inside the lifting seat 42. The operating rotating wheel 47 is rotated to limit the movement of the lifting column 45. At this time, the claw groove 49 opened above the lifting column 45 corresponds to the claw hook 32, and the horizontal support rod 31 is moved downward to make the claw hook 32 fit into the claw groove 49 to complete the docking.

[0067] Then, the power output device 331 is started, and the output shaft of the power output device 331 drives multiple driven gears 334 to rotate through the transmission gear 332 and the special-shaped transmission belt 333, so that the multiple threaded rods 51 move in the multiple driven gears 334, and the floating frame 521 is lowered and placed on the water surface, and the sinking bin 53 is placed in the water. The center of the floating frame 521 forms a detection water surface, and the floating barrel 522 inside the lowered floating frame 521 can provide buoyancy, and the external foreign matter barrier 523 can prevent foreign matter from entering the detection water surface. The sinking bin 53 filters and enters the water to provide pressure, so that the entire horizontal support rod 31 is balanced, and the rotating wheel 47 is operated to rotate again to disengage the rotating rod 46, and the claw hook 32 is buckled. The lifting column 45 can move in the lifting groove 48 as the water level rises, and the installation is completed, thereby achieving the effect of improving the reliability and accuracy of water level monitoring.

[0068] During monitoring, the radar monitor on the radar monitoring frame 27 monitors the detected water surface, and the control box 35 transmits the signal to the remote terminal to achieve the water level monitoring effect; when encountering extreme weather, the radar signal is interfered with. At this time, if the water level rises, the floating frame 521 rises accordingly, and the lifting column 45 moves upward in the lifting groove 48 under the unloading force of the pressure spring 43, and the limit rod 364 moves upward together. The water level rising distance can be judged by the rising distance of the limit rod 364 through the monitoring probe on the radar monitoring frame 27 or on-site exploration. In this way, data support can continue to be provided when the radar signal is interfered with or interrupted, thereby achieving the effect of improving the reliability and stability of the overall system.

[0069] The limiting claw 363 is released from the release groove 362 to make the limiting rod 364 leave the connecting rod 361, and the limiting rod 364 can be used to pull the transverse support rod 31 for steering, so that the floating mechanism 5 is moved to the shore for easy maintenance and installation.
