With the impact of global population growth and climate change, water shortage and pollution problems are becoming increasingly prominent. Scientific and reasonable water resources survey and management have become an important issue in today's society. In the field of hydrological monitoring and water resources survey, evaporation, as one of the important observation contents, refers to the amount of water on the surface of a water body or other wet surface that is converted into water vapor and released into the atmosphere under the influence of various factors. Evaporation is an important link in the water cycle process, and it is of great significance to water resources management, climate research, agricultural irrigation, etc.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 8 As shown, a hydrological and water resources surveying device with a self-protection function described in the present invention comprises a mounting column 1, a floating platform 2 and a water holding seat 3, wherein the mounting column 1 is fixed in a water body to be detected;

[0037] A lifting pump 4 is fixedly connected to the top of the installation column 1; the input end of the lifting pump 4 is connected to a water inlet pipe, and the water inlet pipe is extended to the bottom of the installation column 1; the output end of the lifting pump 4 is connected to a water outlet pipe 5;

[0038] The floating platform 2 is slidably connected to the outside of the mounting column 1; an elastic ring 6 is provided on the side of the floating platform 2; a group of guide rods 7 are evenly distributed inside the elastic ring 6, and the guide rods 7 are slidably connected to the floating platform 2; a buffer spring 8 is sleeved on the outside of the guide rod 7;

[0039] The water holding seat 3 is fixedly connected to the upper side of the floating platform 2 ; an annular groove 9 is arranged on the top of the water holding seat 3 ; an evaporation detection component is arranged inside the annular groove 9 ; the evaporation detection component is used to measure the evaporation amount of water inside the annular groove 9 .

[0040] The hydrological evaporation device in the prior art needs to take samples of the water body to be tested when in use, and then place it inside the device for evaporation observation. However, the evaporation process of water is affected by many factors such as solar radiation, temperature, wind speed, flow rate, etc. The device is usually placed at a monitoring station or on the shore, and there is a certain distance between it and the water source. Therefore, the evaporation process is difficult to fully simulate the real water surface conditions, and the detection results cannot reflect the actual evaporation amount of the water body to be tested, and are not representative.

[0041] The present invention is arranged in a water body to be detected. When the evaporation of the water body needs to be measured, water is pumped through the lifting pump 4, and the water flows into the annular groove 9 along the outlet pipe 5. Then, the evaporation of the water in the annular groove 9 is observed by using the evaporation detection component, so as to understand the evaporation of the water body and provide important reference indicators for hydrological work. The present invention adopts a measure-as-you-go method to observe the evaporation, and in this process, the floating platform 2 floats on the water surface and moves up and down on the surface of the mounting column 1 as the water level fluctuates, so that the water holding seat 3 is close to the water surface, thereby fully simulating the real evaporation process, eliminating interference factors such as solar radiation, air temperature, and wind speed, so that the evaporation conditions are basically consistent with the actual water surface conditions, and the accuracy of the detection results is improved.

[0042] The surveying device is surrounded and protected by providing an elastic ring 6, a guide rod 7 and a buffer spring 8. During the detection process, if floating objects in the water flow hit the elastic ring 6, the impact force can be reduced and buffered by utilizing the deformation functions of the elastic ring 6 and the buffer spring 8, and the deformation direction of the buffer spring 8 can be limited by utilizing the guide rod 7 to prevent the buffer spring 8 from being torsionally damaged, thereby extending the service life of the surveying device.

[0043] In this embodiment, in order to expand the working scope of hydrological observation, a number of sensors can be set on the floating platform 2, such as flow meters, water temperature meters, pH sensors, dissolved oxygen sensors, turbidity sensors, water level meters, etc., to fully understand the local hydrological and water resources conditions.

[0044] The evaporation detection assembly includes a detection groove 10; the detection groove 10 is arranged on the side wall surface of the annular groove 9; a floating block 11 is slidably connected inside the detection groove 10; a distance sensor 12 is embedded on the upper side of the floating block 11, and the distance sensor 12 can be one of infrared, laser, and sonic rangefinders. The floating block 11 floats on the water surface inside the annular groove 9, and the distance sensor 12 is used to measure the distance between it and the top of the detection groove 10. As the evaporation process continues, the amount of water inside the annular groove 9 decreases, and the water level gradually drops. The floating block 11 drives the distance sensor 12 to drop together, and the distance change value measured by the distance sensor 12 can be used to calculate the amount of water evaporation.

[0045] As a preferred embodiment of the present invention, an inclined drain outlet 13 is arranged between the bottom of the annular groove 9 and the outer side of the water holding seat 3, and the drain outlet 13 is located below the detection groove 10; a control board 14 is fixedly connected to the lower side of the floating block 11; the lower end of the control board 14 is slidably connected to the inside of the water holding seat 3 and passes through the drain outlet 13; a connecting groove 15 is arranged on the top of the control board 14.

[0046] During the sampling process, it is advisable to set a filtering device at the bottom of the water inlet pipe to remove larger suspended matter in the water sample. However, the filtered water sample cannot be completely pure, and some small particles of impurities, such as sludge, may still be sucked into the annular groove 9. In order to deal with the above problems, in the initial evaporation stage, the connecting groove 15 is misaligned with the drain port 13, and the control board 14 blocks the drain port 13 to ensure that the water inside the annular groove 9 will not be lost. When the floating block 11 drops to the bottom of the detection groove 10, the connecting groove 15 is aligned with the drain port 13, so that the drain port 13 is in a conducting state. At this time, there is still a certain amount of water left in the annular groove 9, so the remaining water can be discharged outward through the drain port 13 at one time. This operation can discharge all the remaining water and the sludge and other impurities contained therein before they dry up, effectively avoiding the problem that the sludge and other impurities in the water remain, dry, and harden at the bottom of the annular groove 9 when evaporation reaches the final stage, resulting in a reduction in the available space of the annular groove 9.

[0047] The outlet pipes 5 are provided in a group and are evenly distributed above the annular groove 9. By providing multiple outlet pipes 5, when the drain port 13 is connected, the lifting pump 4 can be used to pump water, and then the water flows along the multiple outlet pipes 5 into the annular groove 9 to evenly wash the inside of the annular groove 9, further remove the sludge and other impurities remaining in the annular groove 9, and the sewage generated in this process is discharged outward through the drain port 13.

[0048] As a preferred embodiment of the present invention, the upper side of the floating block 11 is inlaid with a sensing block 16; the upper side of the water receiving seat 3 is fixedly connected with an electromagnet 17 at a position corresponding to the floating block 11, and the electromagnet 17 attracts the sensing block 16 when it is powered on. In order to conduct a new round of evaporation observation, the electromagnet 17 needs to be powered on to attract the sensing block 16, so as to drive the floating block 11 to reset upward to the top of the detection tank 10, and then the lifting pump 4 is used to refill water into the annular tank 9, and then the electromagnet 17 is powered off.

[0049] A group of overflow holes 18 are evenly distributed between the top of the annular groove 9 and the outer side of the water storage seat 3. After the electromagnet 17 drives the floating block 11 to move upward, the height of the floating block 11 is higher than the overflow hole 18, and then when the lifting pump 4 injects water into the annular groove 9, the excess water can flow outward through the overflow hole 18, and the water surface is controlled at the overflow hole 18, and then the electromagnet 17 is controlled to be powered off, and the floating block 11 falls downward to the water surface, so that the initial detection height of the distance sensor 12 can be consistent with the water surface inside the annular groove 9, further improving the accuracy of evaporation measurement.

[0050] As a preferred embodiment of the present invention, a hollow elastic member 19 is fixedly connected to the top of the detection tank 10 at both sides of the distance sensor 12; the surface of the elastic member 19 is connected to an inclined nozzle 20, and the nozzle 20 faces the detection end of the distance sensor 12. When the electromagnet 17 drives the floating block 11 to move upward to the top of the detection tank 10, the floating block 11 can squeeze the elastic member 19, and then the air inside the elastic member 19 is led outward through the nozzle 20 and blows the detection end of the distance sensor 12, blowing away impurities such as dust falling on the surface of the detection end so that it is not blocked, ensuring that the distance sensor 12 can work normally.

[0051] As a preferred embodiment of the present invention, a group of conduits 21 are fixedly connected inside the water holding seat 3; a flow-aiding hole 22 is connected between the conduit 21 and the annular groove 9; a push block 23 is slidably connected inside the flow-aiding hole 22; a return spring 24 is fixedly connected between the push block 23 and the conduit 21; the conduit 21 is connected to a boosting assembly; the boosting assembly is used to intermittently control the pressure increase inside the conduit 21.

[0052] A group of grooves 25 are provided at the lower side of the floating platform 2 ; a water wheel 26 is rotatably connected inside the groove 25 ; a turntable 27 is fixedly connected to the end of the water wheel 26 .

[0053] The boosting assembly includes a boosting cylinder 28 fixedly connected to the inside of the groove 25, and the boosting cylinder 28 is connected to the conduit 21; a piston 29 is slidably connected to the inside of the boosting cylinder 28; a connecting rod 30 is hinged between the piston 29 and the edge of the turntable 27; fluid is added to the inside of the boosting cylinder 28, and the fluid can be water, air, oil or other substances.

[0054] When water flows through the bottom of the floating platform 2, it can drive the water wheel 26 to rotate, and then the water wheel 26 drives the turntable 27 to rotate. The connecting rod 30 is used to control the piston 29 to intermittently reciprocate up and down inside the boosting cylinder 28. When the piston 29 moves upward, it squeezes the fluid inside the boosting cylinder 28, and then the compressed fluid drives the push block 23 to move toward the annular groove 9 inside the flow-aiding hole 22, and the water inside the flow-aiding hole 22 is pushed into the annular groove 9, causing the water sample inside the annular groove 9 to produce a flow effect, thereby simulating the actual flow of the water body, further eliminating the interference of different flow rates on the evaporation process, and this process uses water flow as a driving force, thereby improving the energy-saving effect of the surveying device.

[0055] In order to ensure that the orientation of the groove 25 and the water wheel 26 remains unchanged, a guide groove and a guide block are preferably provided between the mounting column 1 and the floating platform 2 to limit the up and down movement of the floating platform 2, thereby preventing the floating platform 2 from rotating under the action of the water flow and causing the direction of the water wheel 26 to change, so that the water wheel 26 can always face the direction of the water flow, so as to make full use of the water flow to drive the water wheel 26 to rotate.

[0056] As a preferred embodiment of the present invention, a water return hole 31 is connected between the middle of the flow-aiding hole 22 and the annular groove 9; the flow-aiding hole 22 and the water return hole 31 are both tangent to the side wall of the annular groove 9; and one-way valves are provided inside the flow-aiding hole 22 and the water return hole 31.

[0057] The real water flow of natural water bodies usually flows in a single direction. However, due to the reciprocating motion of the push block 23, two completely opposite water flow directions will be generated inside the flow-aiding hole 22, which can easily cause turbulence in the water flow inside the annular groove 9. By providing the return water hole 31 and under the action of the two one-way valves, when the fluid pressure drives the push block 23 to move toward the annular groove 9, the push block 23 pushes the water in the flow-aiding hole 22 toward the annular groove 9. When the reset spring 24 drives the push block 23 to move toward the conduit 21, negative pressure is generated inside the flow-aiding hole 22, and then the return water hole 31 is used to draw water from another position of the annular groove 9 into the flow-aiding hole 22. During this cycle, the water flow directions generated inside the flow-aiding hole 22 and the return water hole 31 are roughly the same (the water flow directions of the flow-aiding hole 22 and the return water hole 31 refer to Figure 8 The solid arrows are all tangent to the annular groove 9 and guide and create momentum for the water flow inside the annular groove 9 along the approximate direction, so that the water inside the annular groove 9 maintains a single-direction circulation flow (the direction of the water flow in the annular groove 9 is referenced Figure 8 The hollow arrows of the annular groove 9 further simulate the real water flow situation, avoid the water flow turbulence caused by the reciprocating motion of the push block 23, improve the authenticity and stability of the water flow inside the annular groove 9, and reduce the evaporation distortion caused by the water flow turbulence.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
