Their setting mode, installation mode and electrical connection mode can be operated by those skilled in the art according to the requirements of their instruction manual, which will not be described here.

[0039] In summary, the working principle of the monitoring device for the hydrological monitoring floating raft is as follows. In use, first, the overall assembly of the monitoring device for the hydrological monitoring floating raft is completed, and the placement state of the overall monitoring device is leveled to make the central evaporation basin 2 in a horizontal posture. Then, the power supply is installed for the electric lifting rod 6, the distance sensor 10, the servo motor 19, the integrated computer 29 and the wireless signal antenna 30, and the pre-operation debugging of the electric lifting rod 6, the distance sensor 10, the servo motor 19, the integrated computer 29 and the wireless signal antenna 30 is performed. During the debugging process, the electric lifting rod 6 should be controlled to operate, so that the transmission frame 7 on the lifting rod of the electric lifting rod 6 is stabilized at a height, and this height is recorded as the zero point height, which is usually selected as the lowest position that the transmission frame 7 can be lowered to. Since the transmission frame 7 and the surrounding frame 8 are connected by the force spring 9, the force spring 9 will be elastically stretched due to the weight of the central evaporation basin 2 and the evaporation sample in the basin. The distance sensor 10 is started, and the distance sensor 10 operates to measure the distance between itself and the top of the transmission frame 7. Then, counterweights are added to the central evaporation basin 2, and the readings of the distance sensor 10 are recorded in real time according to the addition of the counterweights. By gradually increasing the weight of the counterweights, the weight of the overall counterweights after each increase and the corresponding values of the distance sensor 10 are recorded, and a corresponding relationship between the weight of the counterweights and the readings of the distance sensor 10 is formed in the integrated computer 29, so as to facilitate subsequent monitoring data conversion and direct reading after data conversion. During the debugging process, when the maximum added weight of the counterweights is formed in the central evaporation basin 2, the lowest position of the triangular strip 34 should be higher than the maximum waterline of the floating raft platform 1, and it is appropriate that the lowest position of the triangular strip 34 is about 20 cm higher than the maximum waterline, so as to reduce the direct buoyancy of the water surface on the central evaporation basin 2 and avoid the interference of the buoyancy on the accuracy of subsequent evaporation monitoring data collection. In the subsequent actual operation process, the maximum collection amount of the evaporation water sample in the central evaporation basin 2 should be less than the maximum added weight of the counterweights, so as to avoid the elastic deformation of the force spring 9 exceeding the calibration interval in the debugging stage, and to ensure that the monitoring data can always be accurately converted through the preset relationship.

[0040] After the debugging is completed, the weight in the central evaporation basin 2 is completely taken out first, then the hydrological monitoring floating raft is formed into a lowering operation relative to the monitoring water area by the monitoring equipment, and the hydrological monitoring floating raft is formed into position adjustment on the water surface by the form of traction, so that the hydrological monitoring floating raft enters the corresponding monitoring position and performs auxiliary limiting, then the plug body 33 is plugged into the eccentric hole 32 to realize the plugging operation of the eccentric hole 32, then the two electric lifting rods 6 are started at the same time, so that the lifting rods of the two electric lifting rods 6 form synchronous height change, the two lifting frames 4 are first controlled to form synchronous lifting, since the two lifting frames 4 are lifted to drive the two first transmission sleeves 27 to move synchronously, the movement of the two first transmission sleeves 27 drives the two rotating sleeves 26 to rotate synchronously around the mounting hanging seat 25, and the rotating two rotating sleeves 26 drive the two second transmission sleeves 28 to move respectively, and the movement of the two second transmission sleeves 28 lowers the relative height of the lifting circular frame 11, thereby realizing the height reduction of the central evaporation basin 2. After the central evaporation basin 2 is lowered below the water surface, the water sample can be extracted under the flowability of the water itself. After the water sample is extracted, the two transmission frames 7 are lowered synchronously by the synchronous operation of the two electric lifting rods 6, thereby realizing the lifting operation of the central evaporation basin 2 from below the water surface. When the transmission frame 7 enters the zero point height marked in advance, the two electric lifting rods 6 are synchronously stopped, then the distance sensor 10 is started, and the evaporation monitoring state is opened. With the evaporation of the evaporation water sample in the central evaporation basin 2, the water sample in the central evaporation basin 2 will gradually decrease, thereby reducing the gravity of the central evaporation basin 2 and the evaporation water sample. After the gravity is reduced, the tension borne by the two force springs 9 is reduced, thereby reducing the elastic elongation range of the force spring 9. Since the electric lifting rod 6 is in the stopped state, the height of the transmission frame 7 is fixed, and the ring frame 8 is lowered in height under the action of the force spring 9, thereby increasing the monitoring value of the distance sensor 10, that is, the distance between the distance sensor 10 and the lifting frame 4 below it increases. According to the two monitoring data before and after the change of the monitoring value, the integrated computer 29 automatically matches the two gravity values of the evaporation sample before and after evaporation, thereby realizing the evaporation monitoring of the evaporation sample in the central evaporation basin 2. The two gravity values measured in sequence are subtracted, that is, the weight of the evaporation sample evaporated in the corresponding period. Since the two distance sensors 10 are synchronously monitored during the monitoring operation, double data reading can be realized, and two groups of data read in the same time period are compared to ensure the reliability of the monitoring data. That is, the values read by the two distance sensors 10 in the same time are similar or even equal, which can be determined as valid monitoring data. If the values read by the two distance sensors 10 in the same time are greatly different, the evaporation amount needs to be measured further or re-measured to evaluate the reliability of the monitoring data.

[0041] Further, due to the setting of the triangular strips 34 and the cleaning inclined plates 16, and combined with the analysis of the height positions of the triangular strips 34, the cleaning inclined plates 16 and the central evaporation basin 2, when the height of the central evaporation basin 2 is lowered, the triangular strips 34 will first contact the water surface and form immersion interference, and when the triangular strips 34 are immersed in the water surface to a certain depth, the cleaning inclined plates 16 will contact the water surface, so in the process of lowering the height of the central evaporation basin 2 for water sample extraction, the servo motor 19 is powered on in advance to drive the rotation of the contact drive wheel 24 through the transmission shaft 23, the rotation of the contact drive wheel 24 drives the rotation of the revolving outer frame 14 relative to the lifting circular frame 11, the rotation of the revolving outer frame 14 drives the rotation of the central rotating cylinder 12 through the plurality of inner insertion support rods 15, and the rotation of the central rotating cylinder 12 drives the synchronous movement of the plurality of triangular strips 34 at the bottom of the central rotating cylinder 12. At the same time, the rotation of the revolving outer frame 14 also drives the rotation of the plurality of cleaning inclined plates 16, so under the action of the moving triangular strips 34 and the cleaning inclined plates 16, auxiliary interference stirring of the water surface can be formed to rotate and throw away the impurities on the water surface, reduce the impurities in the water into the central evaporation basin 2, and also assist in breaking the thin ice on the water surface during winter monitoring operations, thereby facilitating the extraction of the evaporation sample of the central evaporation basin 2. Since the cleaning inclined plates 16 and the revolving outer frame 14 can rotate, when the ice layer is too hard after the cleaning inclined plates 16 contact the ice layer in the water, the cleaning inclined plates 16 will overcome the protection spring 17 to form relative rotation and rise, thereby achieving protection of the cleaning inclined plates 16 and avoiding overload operation of the electric lifting rod 6. After the sample extraction is completed, even if the evaporation sample in the central evaporation basin 2 forms an ice layer under the action of a relatively cold external environment, the evaporation simulation will not be affected, that is, the evaporation simulation formed by the direct sublimation of ice can also be experimented and monitored in a cold environment. After the monitoring is completed, the height of the central evaporation basin 2 can be lowered by the synchronous operation of the two electric lifting rods 6, and then the central evaporation basin 2 is immersed in the water again, thereby facilitating the cleaning and cleaning of the central evaporation basin 2. At the same time, the plug 33 can be removed from the eccentric hole 32, and the residual evaporation sample in the central evaporation basin 2 can be cleaned through the eccentric hole 32. In order to reduce the influence of special factors on the evaporation simulation, the diameter of the central evaporation basin 2 should be not less than two meters, and the height of the central evaporation basin 2 should be not greater than 0.5 meters, that is, the diameter and height ratio of the central evaporation basin 2 is greater than 4. The setting of the eccentric hole 32 is to ensure the sealing effect of the central evaporation basin 2, and the inner diameter of the eccentric hole 32 should not be too large, generally within 30 centimeters, so the cleaning method of the central evaporation basin 2 through the eccentric hole 32 is obviously less efficient than the cleaning method of the central evaporation basin 2 immersed in water.

[0042] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described.
