Description

Technical Field

[0001] The present application relates to the technical field of water level monitoring, and in particular to a water evaporation monitoring device. Background Art

[0002] In the fields of hydrology, meteorology and environmental science, surface water evaporation is an important part of the water cycle. It is the main part of water loss in water bodies such as reservoirs and lakes, and is also the basic reference for studying terrestrial water evaporation. Surface water evaporation data are needed as an important reference in water resource evaluation, hydrological model determination, water conservancy and hydropower projects, and the planning, design and management of enterprises with large water consumption. Therefore, accurate and efficient monitoring of water evaporation is of great significance for scientific research, engineering design and environmental protection. Water evaporation is one of the main reasons for the decline in surface water levels. As evaporation proceeds, the water in the water body is continuously converted into water vapor and escapes into the atmosphere, resulting in a decrease in the volume of the water body and a drop in the water level.

[0003] The existing technology still has the following problems:

[0004] 1. When the water evaporation monitoring device is in use, since the surface water is mostly soil, the equipment will be tilted during installation. In addition, there are some organisms in the water and soil. If the equipment is not installed stably enough, it will also cause the equipment to tilt. The tilt of the equipment may cause a deviation between the measured value and the actual water level. This deviation may increase with the increase of the tilt angle, and may even cause the measured value to be completely distorted, unable to reflect the actual water level, and thus unable to calculate the evaporation of water.

[0005] 2. Surface water contains a lot of debris, dust, etc., which can easily enter the monitoring tube with the water flow, causing the inlet of the monitoring tube to be blocked, making it impossible for external water to enter the monitoring tube normally, resulting in a certain error in the measurement. Although the existing method of setting a filter at its inlet is adopted, it will still be interfered by debris, dust, etc. in the surface water, making the water flow into the monitoring tube not smooth, resulting in low monitoring quality and inaccurate water level height difference value, making it difficult to calculate the water evaporation value.

[0006] 3. Currently, most of the equipment used for monitoring surface water evaporation has a float assembly in the monitoring tube. Water from the outside enters the monitoring tube, causing the float to move upward in the monitoring tube. However, in actual use, it is impossible to detect in time when the water evaporation reaches a certain level, resulting in missing the best time to maintain the water level, which is not conducive to the sustainable use of water resources and the balanced development of the ecological environment.

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. The use of the support component effectively solves the problem that when the water evaporation monitoring device is in use, the surface water is mostly soil, which causes the equipment to have a certain tilt during installation. In addition, there are some organisms in the water and soil. If the equipment is not installed stably enough, it will also cause the equipment to tilt. The tilt of the equipment may cause a deviation between the measured value and the actual water level. This deviation may increase with the increase of the tilt angle, and may even cause the measured value to be completely distorted, unable to reflect the actual water level situation, and thus unable to calculate the evaporation of water.

[0020] 2. The use of dust-proof components effectively solves the problem that surface water contains a lot of debris, dust, etc., which easily enters the monitoring tube with the water flow, causing the inlet of the monitoring tube to be blocked, making it impossible for external water to enter the monitoring tube normally, resulting in a certain error in the measurement. Although the existing method adopts a filter screen at its inlet, it is still interfered by debris, dust, etc. in the surface water, making the water flow into the monitoring tube not smooth, resulting in low monitoring quality, and inaccurate water level height difference values, making it difficult to calculate the water evaporation value. The present invention can filter out the debris and impurities contained in the surface water during monitoring through the dust-proof component, and at the same time prevent impurities from causing blockage, thereby ensuring smooth water flow.

[0021] 3. The use of the monitoring component effectively solves the problem that most of the current surface water evaporation monitoring equipment is equipped with a float component in the monitoring tube. The outside water enters the monitoring tube and causes the float to move upward in the monitoring tube. However, in actual use, it is impossible to detect in time when the water evaporation reaches a certain level, resulting in missing the best time to maintain the water level, which is not conducive to the sustainable utilization of water resources and the balanced development of the ecological environment. The present invention can accurately calculate the water level difference through the monitoring component, thereby calculating the water evaporation situation, and at the same time, a warning value can be set for the water level. When the water level exceeds the warning value, an alarm can be issued in time to prevent missing the best time to maintain the water level, which is conducive to the sustainable utilization of water resources and the balanced development of the ecological environment.

[0040] If the equipment has a certain inclination during installation, the present invention can keep the equipment stable in soft soil through the support component and can adjust the inclination of the equipment; if it is affected by debris, dust and the like in the surface water, the present invention can filter out the debris and impurities contained in the surface water during monitoring through the dustproof component; if it is impossible to detect in time when the water evaporation reaches a certain level, the present invention can accurately calculate the water level difference through the monitoring component, thereby calculating the water evaporation situation, and at the same time, a warning value can be set for the water level, and an alarm can be issued in time when the water level exceeds the warning value.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] See also Figure 1 As shown, a water evaporation monitoring device includes a monitoring tube 1, the outer surface of the monitoring tube 1 is provided with a supporting component 2, the bottom end of the monitoring tube 1 is fixedly connected with a dustproof component 3, and the inner cavity of the monitoring tube 1 is provided with a monitoring component 4. When in use, the bottom end of the supporting component 2 is inserted into the ground in the water, and water enters the inner cavity of the monitoring tube 1 from the dustproof component 3. The dustproof component 3 is used to filter debris to ensure that the water quality entering the inner cavity of the monitoring tube 1 is good. The monitoring component 4 is used to calculate the water level height difference of the monitoring tube 1, so as to calculate the evaporation of water.

[0043] See also Figure 2 As shown, the support assembly 2 includes a connecting plate 21, which is fixedly connected to the bottom end of the monitoring tube 1, and a fixing ring 22 is fixedly connected to the four corners of the connecting plate 21. An adjusting mechanism 23 is provided at the bottom end of the fixing ring 22, and a supporting leg 24 is fixedly connected to the bottom end of the adjusting mechanism 23. The top end of the monitoring tube 1 is rotatably connected to a horizontal detection mechanism 25, and a reinforcing mechanism 26 is provided in the inner cavity of the supporting leg 24. The bottom end of the supporting leg 24 is fixed in the mud in the water, and the horizontality of the equipment is detected by the horizontal detection mechanism 25. The adjusting mechanism 23 is used to adjust the inclination of the connecting plate 21, that is, to adjust the height of the fixing ring 22 to keep the connecting plate 21 horizontal, and the reinforcing mechanism 26 facilitates the stability of the equipment in the water, while preventing some organisms in the mud in the water from approaching the bottom of the equipment.

[0044] See also Figure 3 and Figure 4As shown, the adjustment mechanism 23 includes a first connecting ring 231, the inner cavity of the first connecting ring 231 is rotatably connected to the first threaded rod 232, the inner cavity of the first connecting ring 231 is slidably connected to the slider 233, the first threaded rod 232 and the slider 233 are threadedly connected, the outer surface of the slider 233 is fixedly installed with a driving rod 234, the outer surface of the first connecting ring 231 is fixedly installed with a storage rod 235, the inner cavity of the storage rod 235 is slidably connected with a lifting rod 236, the top of the lifting rod 236 is fixedly installed with a lifting ring 237, the lower surface of the lifting ring 237 is fixedly installed with a driving block 238, the outer surface of the driving block 238 is provided with a driving groove, the driving rod 234 is slidably connected to the driving groove, the lifting ring 237 is fixedly connected to the fixed ring 22, the first connecting ring 231 and the supporting leg 2 4 is fixedly connected.

The first threaded rod 232 is rotated to drive the slider 233 to slide on the first connecting ring 231. The sliding of the first connecting ring 231 drives the driving rod 234 to slide in the driving groove on the driving block 238. At this time, the lifting rod 236 slides in the inner cavity of the storage rod 235 to change the height of the lifting ring 237, thereby changing the height of the corresponding fixing ring 22. That is, after the support leg 24 is inserted into the water ground, the monitoring tube 1 is tilted due to the unevenness of the water ground, etc. The vertical degree of the monitoring tube 1 is achieved by adjusting the height of the fixing ring 22, which is convenient for making the liquid level in the inner cavity of the monitoring tube 1 level, so that the numerical calculation of water level evaporation is more accurate.

[0045] See also Figure 2 and Figure 5As shown, the horizontal detection mechanism 25 includes a rotating ring 251, a horizontal frame 252 is fixedly installed on the outer surface of the rotating ring 251, a horizontal block 253 is provided in the inner cavity of the horizontal frame 252, first rotating rods 254 are rotatably connected at both ends of the horizontal block 253, a first pointer 255 is fixedly installed in the middle part of the horizontal block 253, a configuration ball is provided at the bottom end of the horizontal block 253, the first rotating rod 254 is rollingly connected to the inner cavity of the horizontal frame 252, the inner cavity of the horizontal frame 252 is symmetrically distributed about the middle part of the horizontal frame 252, the first pointer 255 points to the middle part of the horizontal frame 252, and scale lines are provided on the outer surface of the rotating ring 251. 1 is rotatably connected to the monitoring tube 1.

The tilting of the rotating ring 251 drives the first rotating rod 254 to roll in the inner cavity of the horizontal frame 252, and the horizontal block 253 moves in the inner cavity of the horizontal frame 252. At this time, the direction of the first pointer 255 changes and is no longer in the middle position of the horizontal frame 252. By rotating the rotating ring 251 on the outer surface of the monitoring tube 1 and observing the direction of the first pointer 255, it is convenient to adjust the height according to the offset of the first pointer 255 in cooperation with the adjusting mechanism 23, and adjust the horizontality of the connecting plate 21, so that the monitoring tube 1 remains vertical, which is convenient for the subsequent calculation of the water level difference and the evaporation of water.

When the inclination of the monitoring tube 1 is adjusted, the second connecting ring 262 is rotated in the inner cavity of the sliding groove 267 by rotating the adjusting ring 261. At this time, the second connecting ring 262 The rotation of the connecting ring 262 drives the adjustment groove 263 to rotate, and the rotation of the adjustment groove 263 drives the sliding rod 264 to slide in the inner cavity of the adjusting groove 263. The sliding of the sliding rod 264 drives the sliding bar 265 to slide on the inner wall of the supporting leg 24. The movement of the sliding bar 265 drives the insertion rod 266 to slide on the supporting leg 24, so that the sliding bar 265 and the inner wall of the supporting leg 24 fit together. At this time, the insertion rod 266 is exposed, that is, after the bottom end of the supporting leg 24 is inserted into the soil, the soil is inserted again through the insertion rod 266. The contact area between the insertion rod 266 and the soil is increased, thereby increasing the range of action of the friction force and the extrusion force to prevent the supporting leg 24 from tipping over, increase the stability of the supporting leg 24, and at the same time prevent some organisms in the soil from approaching the insertion rod 266, thereby preventing some organisms from contacting the supporting leg 24, which has a certain auxiliary effect on the stability of the monitoring tube 1.
