Description

Technical Field

[0001] This invention relates to the field of evaporation technology, specifically to a precise water replenishment mechanism for an automatic monitoring system for evaporation during ice ages. Background Technology

[0002] Evaporation is a key component of the hydrological cycle and a crucial element in hydrological monitoring. Water surface evaporation data provides vital support and information for flood control, drought relief, and water resource management. Automatic evaporation monitoring during the freezing period refers to the technology of automatically monitoring the evaporation rate from water surfaces during the freezing period. This technology involves modifying traditional water surface evaporators and installing core weighing components, enabling automatic evaporation stations to achieve the expected accuracy in comparing observation results during the freezing period, thus initially realizing year-round online monitoring of evaporation. The significance of this technology lies in improving the accuracy and stability of monitoring, filling the gap in year-round automatic observation by automatic evaporation stations in freezing areas, and providing more reliable data support for hydrological analysis.

[0003] In existing technologies, although the evaporating dish can be automatically and quantitatively replenished with water in real time during use, a small amount of water still drips down from the bottom of the water pipe into the evaporating dish after the water is discharged into the dish. This makes it impossible for the existing water replenishment mechanism to accurately replenish the water in the evaporating dish, which will have an adverse effect on the evaporation test, resulting in errors in the evaporation data and low data reliability, which is not conducive to the smooth progress of the evaporation test. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a precise water replenishment mechanism for an automatic monitoring system for evaporation during ice ages.

[0005] A precision water replenishment mechanism for an automatic evaporation monitoring system during glacial periods includes an evaporating dish, a device body, and a base. The evaporating dish is placed on top of the device body. A rotating plate is rotatably mounted on the top of the base, and a movable plate is slidably mounted on the top of the rotating plate. A movable seat is slidably mounted on the side of the movable plate near the device body. A first water pipe is installed inside the movable seat. One end of the first water pipe is connected to a flexible hose via a flange, and the other end of the first water pipe is fitted with a housing. A second water pipe is rotatably mounted inside the housing, and a drive mechanism for rotating the second water pipe is installed inside the housing. A guide plate is provided at the bottom of the second water pipe, and protective mechanisms for shielding the top of the evaporating dish are provided on both outer walls of the guide plate.

[0006] Optionally, the top of the rotating plate is provided with a first groove, and a first lead screw is rotatably installed inside the first groove. The bottom end of the moving plate is threadedly engaged with the outer wall of the first lead screw.

[0007] Optionally, a second groove is provided on the outer wall of the movable plate near the device body, and a second lead screw is rotatably installed inside the second groove, with the movable seat threadedly engaged with the outer wall of the second lead screw.

[0008] Optionally, the drive mechanism includes a first motor installed inside the housing, a first gear installed at the output end of the first motor, and a second gear installed on the outer wall of one end of the second water pipe inside the housing, the second gear meshing with the first gear.

[0009] Optionally, the guide plate is rotatably connected to the outer wall of the second water pipe through two connecting blocks at the top. A fixing plate is installed on the outer wall of the second water pipe near the guide plate. A second motor is installed on one side of the outer wall of the fixing plate. The output end of the second motor is connected to the rotating part of one of the connecting blocks.

[0010] Optionally, the protective mechanism includes two storage slots inside the guide plate, each storage slot having an extension plate slidably installed inside. The outer walls of the two extension plates on adjacent sides are connected to the inner walls of the storage slots via two electric telescopic rods.

[0011] Optionally, the outer walls of both sides of the guide plate are provided with sliding grooves that communicate with the two receiving slots, and the outer walls of both sides of the two extension plates are equipped with sliders that slide back and forth inside the sliding grooves. The ends of the two sliders away from the extension plates are rotatably mounted with flexible metal plates.

[0012] Optionally, two electromagnets are installed on the outer walls of both sides of the guide plate. When the two flexible metal plates are in a straight line, the two electromagnets are magnetically attracted to the flexible metal plates after being energized.

[0013] Optionally, a third groove is provided on the side of each of the two flexible metal plates away from the guide plate, and a semi-circular airbag is installed inside each of the two third grooves.

[0014] Optionally, rotating rods are rotatably mounted on the top of both ends of the guide plate, and openings are provided at both ends of the guide plate for the rotating rods to rotate up and down. An extension rod is installed at the end of each rotating rod away from the rotating part. A slot adapted to the size of the two extension rods is provided on the top of the base. The outer wall of the side of the two rotating rods that are close to each other is curved. A cleaning brush is installed at the bottom of the guide plate.

[0015] The beneficial effects of this invention are reflected in:

[0016] 1. In this invention, after the second water pipe has finished replenishing the water to the evaporating dish, the dripping water can be guided to a position away from the evaporating dish by the cooperation of the guide plate and the two extension plates, so as to prevent the water dripping down from the second water pipe from entering the evaporating dish. This achieves the effect of accurately replenishing the water to the evaporating dish, making the evaporation test data more accurate and the test data more reliable.

[0017] 2. In this invention, since the evaporating dish needs to be in the external environment for a long time during use, a lot of impurities will accumulate inside the evaporating dish. When a lot of impurities are found inside the evaporating dish, the second lead screw is controlled to drive the guide plate into the interior of the evaporating dish until the cleaning brush set at the bottom of the guide plate contacts the inner bottom surface of the evaporating dish. At this time, the drive mechanism drives the second water pipe to rotate, which in turn drives the guide plate and the cleaning brush to rotate together inside the evaporating dish. During the rotation, the cleaning brush can brush and clean the impurities on the inner bottom surface of the evaporating dish, which facilitates the automatic removal of impurities on the inner bottom surface of the evaporating dish.

[0018] 3. In this invention, the two rotating rods, in cooperation with other components, can scrape and clean the impurities on the circular inner wall of the evaporating dish and the gap between the circular inner wall and the inner bottom surface, thereby achieving the effect of thoroughly cleaning the impurities accumulated on the inner wall of the evaporating dish.

[0019] 4. In this invention, when there is rain or snow in the external environment, the two electric telescopic rods inside the two storage slots are controlled to push the two extension plates to move and extend, which drives the corresponding sliders to pull the two ends of the two flexible metal plates, causing the two flexible metal plates to be pulled into a straight state. After the two flexible metal plates are in close contact with the outer wall of the guide plate, the airbags inside the two third grooves are controlled to inflate. At this time, the guide plate, the two extension plates and the two inflated airbags can shield and protect the top of the evaporating dish, preventing rain and snow from entering the interior of the evaporating dish and affecting the subsequent use of the evaporating dish.

[0032] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0034] like Figures 1-10As shown, a precision water replenishment mechanism for an automatic evaporation monitoring system during glacial periods includes an evaporating dish 2, a device body 1, and a base 3. The evaporating dish 2 is placed on top of the device body 1. A rotating plate 4 is rotatably mounted on the top of the base 3, and a movable plate 5 is slidably mounted on the top of the rotating plate 4. A movable seat 14 is slidably mounted on the side of the movable plate 5 near the device body 1. A first water pipe 7 is installed inside the movable seat 14. One end of the first water pipe 7 is connected to a flexible hose 6 via a flange 15, and the other end of the first water pipe 7 is installed with a housing 8. A second water pipe 9 is rotatably mounted inside the housing 8. A drive mechanism for driving the rotation of the second water pipe 9 is installed inside the housing 8. A guide plate 10 is provided at the bottom end of the second water pipe 9, and protective mechanisms for shielding the top of the evaporating dish 2 are provided on both sides of the outer wall of the guide plate 10. A first driving device is pre-installed inside the base 3. The output end of the first driving device is connected to the rotating part of the rotating plate 4, thereby driving the rotating plate 4 and multiple components on its top to rotate and adjust synchronously.

[0035] As a technical optimization of the present invention, a first groove is provided on the top of the rotating plate 4, and a first lead screw 12 is rotatably installed inside the first groove. The bottom end of the moving plate 5 is threadedly engaged with the outer wall of the first lead screw 12. A second driving device is preset on one side of the outer wall of the rotating plate 4. The output end of the second driving device is connected to one end of the first lead screw 12, which can drive the first lead screw 12 to rotate inside the first groove, so that the moving plate 5 can move back and forth and adjust as the first lead screw 12 rotates.

[0036] As a technical optimization of the present invention, a second groove is provided on the outer wall of the movable plate 5 near the device body 1. A second lead screw 13 is rotatably installed inside the second groove, and the movable seat 14 is threadedly engaged with the outer wall of the second lead screw 13. A third driving device is preset at the top of the movable plate 5. The output end of the third driving device is connected to one end of the second lead screw 13, which can drive the second lead screw 13 to rotate inside the second groove, so that the movable seat 14 can move up and down as the second lead screw 13 rotates, thereby driving the first water pipe 7 to move up and down synchronously.

[0037] As a technical optimization of the present invention, the driving mechanism includes a first motor 32 installed inside the housing 8, a first gear 16 installed at the output end of the first motor 32, and a second gear 17 installed on the outer wall of one end of the second water pipe 9 located inside the housing 8. The second gear 17 meshes with the first gear 16. While the first motor 32 drives the first gear 16 to rotate, it can also drive the second gear 17 meshing with the first gear 16 to rotate synchronously, thereby driving the second water pipe 9 to rotate synchronously and adjust inside the housing 8.

[0038] As a technical optimization of the present invention, the guide plate 10 is rotatably connected to the outer wall of the second water pipe 9 via two connecting blocks at its top. A fixing plate 18 is installed on the outer wall of the second water pipe 9 near the guide plate 10. A second motor 19 is installed on one side of the outer wall of the fixing plate 18. The output end of the second motor 19 is connected to the rotating part of one of the connecting blocks. The second motor 19 can drive one of the connecting blocks to rotate and adjust. Since the connecting block is installed at the top of the guide plate 10, it can drive the guide plate 10 to rotate and adjust at the bottom end of the second water pipe 9, thereby driving the other connecting block to rotate as well.

[0039] As an optimized technical solution of the present invention, the protective mechanism includes two receiving slots 25 opened inside the guide plate 10. An extension plate 26 is slidably installed inside each of the two receiving slots 25. The outer walls of the adjacent sides of the two extension plates 26 are connected to the inner walls of the receiving slots 25 via two electric telescopic rods 28. During the extension and retraction of the telescopic ends of the two electric telescopic rods 28, the corresponding extension plates 26 can be moved and adjusted within the receiving slots 25, allowing the extension plates 26 to extend or retract within the receiving slots 25 as the telescopic ends of the electric telescopic rods 28 extend and retract.

[0040] As a technical optimization of the present invention, the outer walls of both sides of the guide plate 10 are provided with sliding grooves 24 that communicate with the two receiving slots 25. The outer walls of both sides of the two extension plates 26 are each equipped with sliders 29 that slide back and forth inside the sliding grooves 24. The ends of the two sliders 29 away from the extension plates 26 are rotatably mounted with flexible metal plates 20. While the extension plates 26 move back and forth inside the receiving slots 25, they can drive the sliders 29 mounted on their outer walls to move synchronously inside the sliding grooves 24. When the two extension plates 26 extend in opposite directions, they can pull the two ends of the flexible metal plates 20 with the help of the two sliders 29, causing the flexible metal plates 20 to be stretched into a straight line. When the two extension plates 26 move back to their original position in opposite directions, they drive the two sliders 29 to squeeze the flexible metal plates 20, causing the two flexible metal plates 20 to deform into an arc shape on both sides of the guide plate 10.

[0041] As a technical optimization of the present invention, two electromagnets 23 are installed on both outer walls of the guide plate 10. When the two flexible metal plates 20 are in a straight line, the two electromagnets 23 are magnetically attracted to the flexible metal plates 20 after being energized. After the two flexible metal plates 20 are moved and pulled to a straight line by the corresponding two sliders 29, the two electromagnets 23 are energized to generate magnetism, which can provide an auxiliary magnetic attraction and fixation effect for the straight flexible metal plates 20.

[0042] As a technical optimization of the present invention, each of the two flexible metal plates 20 has a third groove 30 on the side away from the guide plate 10, and a semi-circular airbag 31 is installed inside each of the two third grooves 30. When not inflated, the two airbags 31 are respectively housed inside the corresponding third groove 30, and when inflated, they expand outward from the inside of the corresponding third groove 30.

[0043] As a technical optimization of the present invention, rotating rods 21 are rotatably mounted on the top of both ends of the guide plate 10. Openings 27 are provided at both ends of the guide plate 10 for the rotating rods 21 to rotate up and down. Extension rods 22 are installed at the ends of the two rotating rods 21 away from their rotating parts. Slots 11, matching the size of the two extension rods 22, are provided on the top of the base 3. The outer walls of the sides of the two rotating rods 21 that are close to each other are curved. A cleaning brush 33 is installed at the bottom of the guide plate 10. A fourth driving device is pre-installed at the top of both ends of the guide plate 10. The output ends of the two fourth driving devices are respectively connected to the rotating parts of the corresponding rotating rods 21, thereby driving the two rotating rods 21 and the extension rods 22 to rotate and adjust at both ends of the guide plate 10.

[0044] In this invention, when the user uses the device, a water tank is pre-set around the evaporating dish 2. The end of the flexible hose 6 away from the first water pipe 7 is connected to the output end of the water pump. The input end of the water pump is located inside the water tank. When it is necessary to replenish water inside the evaporating dish 2, the second motor 19 is controlled to drive the guide plate 10 to rotate 90 degrees clockwise or counterclockwise, driving the guide plate 10 and other components to rotate to a state parallel to the second water pipe 9, so that the bottom of the second water pipe 9 is not obstructed. Then, the water pump can be started to draw water out of the water tank and discharge it into the flexible hose 6, the first water pipe 7 and the second water pipe 9. The water is discharged downward through the bottom end of the second water pipe 9 into the evaporating dish 2, thus completing the water replenishment work of the evaporating dish 2.

[0045] After the water replenishment of evaporating dish 2 is completed, the second motor 19 drives the guide plate 10 to rotate and reset, so that the guide plate 10 is in a horizontal state at the bottom of the second water pipe 9. The two electric telescopic rods 28 inside the two receiving slots 25 extend together, pushing the two extension plates 26 outwards from inside their respective receiving slots 25 until the ends of the two extension plates 26 are far apart from the evaporating dish 2. At this point, the water remaining inside the second water pipe 9 and dripping downwards will fall onto the top of the guide plate 10, which, together with the two extended extension plates 26, can... The dripping water is guided to a position away from the evaporating dish 2. Then, the rotating plate 4 drives multiple components, including the moving plate 5, to rotate 90 degrees, which in turn drives multiple components, including the second water pipe 9 and the guide plate 10, to rotate above the base 3. This avoids obstructing the top of the evaporating dish 2. The remaining water is guided out through the guide plate 10 and the two extension plates 26, preventing the remaining water from dripping into the evaporating dish 2 and causing excessive water to be added to the evaporating dish 2. This achieves a precise water replenishment effect for the evaporating dish 2, making the evaporation test data more accurate and reliable.

[0046] Since the evaporating dish 2 needs to be in the external environment for a long time during use, a lot of impurities will accumulate inside the evaporating dish 2, affecting the subsequent evaporation test. When a lot of impurities are found inside the evaporating dish 2, the second lead screw 13 is controlled to rotate, which drives multiple components such as the moving seat 14, the first water pipe 7 and the second water pipe 9 to move downward together until the guide plate 10 at the bottom of the second water pipe 9 enters the interior of the evaporating dish 2. Since the length of the guide plate 10 is adapted to the inner diameter of the evaporating dish 2, when the guide plate 10 is driven and moved to contact the inner bottom surface of the evaporating dish 2, the cleaning brush 33 set at the bottom of the guide plate 10 will contact the inner bottom surface of the evaporating dish 2. At this time, the first motor 32 is controlled to drive the first gear 16 and the second gear 17 to rotate together, so that the second gear 17 can drive the second water pipe 9 to rotate, which in turn drives the guide plate 10 and the cleaning brush 33 to rotate together inside the evaporating dish 2. During the rotation, the cleaning brush 33 can brush and clean the impurities on the inner bottom surface of the evaporating dish 2, which facilitates the automatic removal of impurities on the inner bottom surface of the evaporating dish 2.

[0047] Next, control the second lead screw 13 to reverse, causing multiple components such as the moving seat 14, the first water pipe 7, and the second water pipe 9 to move upwards together. This moves the guide plate 10 from inside the evaporating dish 2 upwards to a position higher than the evaporating dish 2. At this time, control the two rotating rods 21 to rotate downwards at the top of both ends of the guide plate 10, causing the two extension rods 22 to rotate together until the bottom of the guide plate 10 is in a vertical position. Since the outer wall of one side of both rotating rods 21 is curved, and the curved surface of one side of both rotating rods 21 is adapted to the inner wall of the evaporating dish 2, after the two rotating rods 21 rotate downwards to the bottom of the guide plate 10, the curved surface of one side of both rotating rods 21 is adapted to the inner wall of the evaporating dish 2. When the inner walls of the evaporating dish 2 are close together, the second screw 13 is rotated again, causing the guide plate 10 to move downward synchronously. This allows the two rotating rods 21 and the extension rod 22, which have rotated to a vertical position, to enter the interior of the evaporating dish 2 first. The arc surfaces on one side of the two rotating rods 21 abut against the inner wall of the evaporating dish 2. At this time, the rotation of the second water pipe 9 drives the two rotating rods 21 to rotate together inside the evaporating dish 2. With the help of the two rotating rods 21 and the extension rod 22, impurities on the circular inner wall of the evaporating dish 2, as well as the gap between the circular inner wall and the inner bottom surface, can be scraped and cleaned, thus achieving the effect of thoroughly cleaning the impurities accumulated on the inner wall of the evaporating dish 2.

[0048] Furthermore, while cleaning the impurities on the inner wall of the evaporating dish 2 using the cleaning brush 33 and the two rotating rods 21, the external water pump can also be started, allowing water to be discharged from the bottom of the second water pipe 9 to the top of the guide plate 10 and then discharged downwards from both ends of the guide plate 10 into the interior of the evaporating dish 2. This wets the impurities on the inner wall of the evaporating dish 2, improving the efficiency of the cleaning brush 33 and the two rotating rods 21 in cleaning the impurities on the inner wall of the evaporating dish 2. After the cleaning brush 33 and the two rotating rods 21 have cleaned the impurities on the inner wall of the evaporating dish 2, the evaporating dish 2 can be manually removed from the top of the device body 1, the impurities cleaned out can be poured out, and the remaining impurities inside the evaporating dish 2 can be rinsed with water. There is no need for manual cleaning of the evaporating dish 2 with tools, which facilitates the rapid removal of impurities from the inner wall of the evaporating dish 2.

[0049] If there is severe weather such as strong winds in the external environment, the evaporating dish 2 has already been moved indoors by staff. To ensure the safety of multiple components such as the first water pipe 7 and the second water pipe 9, the first lead screw 12 can be controlled to rotate first, driving the moving plate 5 and multiple components such as the first water pipe 7 to move away from the evaporating dish 2. After moving multiple components such as the guide plate 10 to the designated position, ... Figure 4As shown, by controlling the rotating plate 4 to drive the guide plate 10 and other components to rotate 90 degrees clockwise, the guide plate 10 and other components rotate together to the top of the base 3. Then, by controlling the two rotating rods 21 to rotate downwards to a vertical position, the second lead screw 13 is controlled to rotate, driving the moving seat 14 and the first water pipe 7 and other components to move downwards together until the two extension rods 22 are inserted into the corresponding slots 11. At this time, the guide plate 10 and other components can be limited and fixed by the extension rods 22 and rotating rods 21 inserted into the slots 11, avoiding the instability of the guide plate 10, the first water pipe 7 and the second water pipe 9 and other components in windy weather, which may cause these components to be easily damaged. This improves the safety of these components during use and extends their service life.

[0050] If the evaporating dish 2 is not removed by the staff and remains on top of the device body 1, in order to ensure the safety of the evaporating dish 2 and multiple components such as the first water pipe 7 and the second water pipe 9, the guide plate 10 can be moved downwards by controlling the second lead screw 13 until the cleaning brush 33 at the bottom of the guide plate 10 is in close contact with the inner bottom surface of the evaporating dish 2. At this time, the downward moving guide plate 10 and other components have a pressing and limiting effect on the evaporating dish 2, preventing the evaporating dish 2 from being blown off the top of the device body 1, and also limiting and fixing the guide plate 10 and other components, thereby improving the stability and safety of the entire device in windy weather.

[0051] If rain or snow occurs in the external environment, the evaporation experiment can no longer be carried out. In this case, it can be done as follows: Figure 1 , Figures 8-10 As shown, at this time, the guide plate 10 is located directly above the evaporating dish 2 and flush with the top of the evaporating dish 2. By controlling the extension ends of the two electric telescopic rods 28 inside the two receiving slots 25 to extend together, the two extension plates 26 are pushed to move and extend together in the opposite direction inside the corresponding receiving slots 25. After the two extension plates 26 move to a position longer than the diameter of the evaporating dish 2, the corresponding sliders 29 are moved out from the inside of the sliding grooves 24. This causes the two sliders 29 to have a pulling effect on the two ends of the two flexible metal plates 20 while moving in the opposite direction, causing the two flexible metal plates 20 to be pulled into a straight state. At this time, the two electromagnets 23 on both sides of the outer wall of the guide plate 10 can be energized simultaneously to generate magnetism, which has an auxiliary magnetic attraction and fixing effect on the two straight flexible metal plates 20. After the two flexible metal plates 20 are tightly abutting against the outer wall of the guide plate 10, the air bladders 31 inside the two third grooves 30 are inflated. Figure 10As shown in the diagram, the guide plate 10, the two extension plates 26, and the two expanded airbags 31 can shield and protect the top of the evaporating dish 2, preventing external rainwater and snowflakes from entering the interior of the evaporating dish 2 and affecting its subsequent use.

[0052] Furthermore, when a large amount of snow accumulates on the tops of the two airbags 31, the guide plate 10, and the two extension plates 26, the drive mechanism can be controlled to rotate multiple components such as the second water pipe 9 and the guide plate 10 together, causing the accumulated snow on the tops of the two airbags 31, the guide plate 10, and the two extension plates 26 to be rotated and flung out, thus preventing a large amount of snow from accumulating on the tops of the two airbags 31, the guide plate 10, and the two extension plates 26 and improving the protection effect on the evaporating dish 2.

[0053] If an evaporation test is conducted in winter, the water inside the evaporating dish 2 will freeze when the temperature drops below zero. At this time, the second lead screw 13 can be rotated to drive the guide plate 10 downward into the evaporating dish 2. As the guide plate 10 moves downward inside the evaporating dish 2, it can crush the ice inside the evaporating dish 2, ensuring that the water inside the evaporating dish 2 is not affected by the surface ice. The evaporating dish 2 can continue to conduct the evaporation test, or the ice can be removed manually and an appropriate amount of water can be added back into the evaporating dish 2 through the second water pipe 9 to avoid the ice affecting the smooth progress of the evaporation test. This makes it convenient for people to conduct evaporation tests in winter using the evaporating dish 2, and can also improve the applicability of multiple components such as the guide plate 10 in actual use.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
