[0002] Monitoring of hydrological changes in forest ecology is a method used by water conservancy departments to collect real-time data on hydrological parameters such as rivers, lakes, reservoirs, channels and groundwater. The monitoring content includes: water level, flow, flow rate, rainfall (snow), evaporation, sediment, ice, soil moisture, water quality, etc.

[0003] When monitoring rivers in forest ecology, water level monitoring components are often used to monitor the height of the water level. However, most existing devices fix the devices for collecting water levels on the riverside, and can only monitor the overall water level, but cannot monitor the water height at different locations in the river. At the same time, since the forest ecology contains a large amount of sediment, the sediment will be deposited at the bottom of the river under long-term water erosion, causing blockage of the river and sometimes even flooding. The existing technology is not convenient for monitoring the height of the sediment in the entire river. Summary of the invention

[0013] S1. When measuring the water level, the controller controls the operation of the pay-off motor to pay out the fixed rope. At this time, the force detected by the pressure sensor is the gravity of the weight and the fixed rope minus the buoyancy of the weight and the fixed rope. This value is relatively large.

The water depth at a point can be determined according to the number of revolutions of the winding wheel controlled by the pay-off motor.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The present invention provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a forest hydrological change monitoring device and a monitoring method thereof, a forest hydrological change monitoring device, includes a floating plate 1, the floating plate 1 can translate on the detection water surface, the top of the floating plate 1 is symmetrically fixedly installed with columns 2, the tops of the four columns 2 are fixedly installed with fixed frames 3, the interior of the fixed frame 3 is rolled up with a measuring rope 4, the bottom of the measuring rope 4 is fixedly installed with a heavy hammer 5 for detecting the water depth, fixed rods 6 are fixedly installed on both sides of the water surface, the tops of the fixed rods 6 are rotatably installed with winding wheels 7, a fixed rope 8 is wound between the two winding wheels 7, half of the fixed rope 8 is fixedly installed at one end of the floating plate 1, and the other half of the fixed rope 8 is slidably installed at the other end of the floating plate 1.

[0026] like Figures 1 to 4 As shown, the interior of the fixed frame 3 is symmetrically provided with storage grooves 9, a squeezing plate 10 is slidably installed between the two storage grooves 9, pressure sensors 11 are fixedly installed at the bottom of the inner wall of the fixed frame 3 corresponding to the two end positions of the squeezing plate 10, the squeezing plate 10 is in squeezing contact with the pressure sensor 11, a pay-off motor 12 is fixedly installed in the middle of the squeezing plate 10, a winding wheel 13 is fixedly installed on the output end of the pay-off motor 12 through the squeezing plate 10, a fixed rope 8 is wound around the middle of the winding wheel 13, and a controller 14 for controlling the signal transmission of the pay-off motor 12 and the pressure sensor 11 is fixedly installed inside the fixed frame 3, and the controller 14 transmits monitoring data in real time via wireless communication.

[0027] The controller 14 controls the operation of the pay-off motor 12 to pay out the fixed rope 8. When the force detected by the pressure sensor 11 is small, it can be determined that the weight 5 has reached the water body. The number of revolutions of the winding wheel 13 controlled by the pay-off motor 12 can be used to determine the water depth here, which is used to monitor the water depth at a certain position.

[0028] like Figures 1 to 4As shown, water flow power generation components 15 are symmetrically fixedly installed on both sides of the floating plate 1, blades 16 are fixedly installed on the input end of the water flow power generation component 15, and batteries 17 are fixedly installed inside the fixing frame 3.

[0029] The blades 16 are driven to rotate by the water flow, and the water flow power generation assembly 15 is operated to generate electricity, which is stored in the battery 17 for use in the pay-off motor 12 , the pressure sensor 11 and the controller 14 .

[0030] like Figures 1 to 4 As shown, the fixing rope 8 is wound around the winding wheel 7 three times.

[0031] The friction between the fixed rope 8 and the winding wheel 7 is increased to ensure the conveyance of the fixed rope 8 when the winding wheel 7 rotates.

[0032] like Figures 1 to 4 As shown, a mounting frame 18 is fixedly mounted on the top of one of the fixing rods 6 , a moving motor 19 is fixedly mounted on the top of the inner wall of the mounting frame 18 , and an output end of the moving motor 19 is fixedly connected to the winding wheel 7 .

[0033] The mobile motor 19 controls the reel 7 to rotate. When the reel 7 rotates, it pulls the half section of the fixed rope 8, which drives the floating plate 1 to move horizontally on the detection water surface, so as to detect the water height of the whole water body.

[0034] like Figures 1 to 4 As shown, a mounting plate 20 is installed on one side of one of the fixed rods 6, and the mounting plate 20 is fixedly installed on the shore. A first rotating shaft 21 is fixedly installed on the top of the mounting plate 20, and a first winding wheel 22 is equidistantly rotatably installed in the middle of the first rotating shaft 21. A slide groove 23 is opened in the middle of the mounting plate 20, and a slider 24 is slidably installed inside the slide groove 23. A second rotating shaft 25 is fixedly installed in the middle of the slider 24, and a second winding wheel 26 is equidistantly rotatably installed in the middle of the second rotating shaft 25. The second winding wheel 26 is staggered with the first winding wheel 22, and the fixing rope 8 is staggered and wound between the second winding wheel 26 and the first winding wheel 22.

[0035] When the water level changes, the tensioning degree of the fixing rope 8 will change. By interlacing the fixing rope 8 between the second winding wheel 26 and the first winding wheel 22, the fixing rope 8 will have a lifting force on the second winding wheel 26 or the second winding wheel 26 will have a downward pressure on the fixing rope 8, which is used to drive the height change of the second winding wheel 26 and ensure that the fixing rope 8 is continuously in a tensioned state.

[0036] like Figures 1 to 4 As shown, a baffle 27 is fixedly mounted on one end of the bottom of the floating plate 1, and the floating plate 1 is arranged in a triangular shape.

[0037] The baffle 27 can protect the blades 16 to prevent the substances in the water from winding around the blades 16 . Meanwhile, the triangular floating plate 1 pushes the substances in the water to both sides of the floating plate 1 to prevent them from accumulating at the ends of the floating plate 1 .

[0038] like Figures 1 to 4 As shown, a monitoring method using a forest hydrological change monitoring device as described in any one of claims 1 to 7 comprises the following steps:

[0039] S1. When measuring the water level, the controller 14 controls the pay-off motor 12 to operate and pay out the fixed rope 8. At this time, the force detected by the pressure sensor 11 is the gravity of the weight 5 and the fixed rope 8 minus the buoyancy of the weight 5 and the fixed rope 8. This value is relatively large. When the weight 5 contacts the bottom of the water, the force detected by the pressure sensor 11 is only the gravity of the fixed rope 8 minus the buoyancy of the fixed rope 8. This value is relatively small. Therefore, it can be determined that the weight 5 has reached the water body at this time. The depth of the water body here can be determined according to the number of revolutions of the winding wheel 13 controlled by the pay-off motor 12, and then the weight 5 is moved to the initial height;

[0040] S2, the reel 7 is controlled to rotate by the mobile motor 19, and the half section of the fixed rope 8 is pulled when the reel 7 rotates, and the floating plate 1 is driven to move horizontally on the detection water surface, and then the fixed rope 8 is repeatedly released, and the water depth at the lower position can be measured in the same way as in S1, and the water height of the whole water body can be measured by repeating this process;

[0041] S3. The numerical value is transmitted to the receiver through the controller 14, and the received data can be plotted into a three-dimensional image according to the algorithm to display the overall water depth of the water body. At the same time, the water level value is monitored by the instrument at the water's edge, and the original water level value is marked. When the water level does not change, the sedimentation height of the silt at the bottom of the water body is obtained by subtracting the value detected by S1 and S2 this time from the value detected by S1 and S2 last time. When the water level changes, the value monitored by S1 and S2 this time is subtracted from the change in water level, and then subtracted from the value monitored by S1 and S2 last time, and the sedimentation height of the silt at the bottom of the water body is also obtained.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
