Description

Technical Field

[0001] The utility model relates to the technical field of reservoir sampling, in particular to a water surface anti-freezing device. Background Technique

[0002] Reservoir water quality sampling is a key link to ensure the accuracy and timeliness of water quality monitoring, and plays an irreplaceable role in monitoring the water quality changes of reservoirs, evaluating the water environment status, and ensuring water use safety;

[0003] In winter, the reservoir sampling point faces the problem of water surface icing, which brings difficulties to the sampling work. The traditional anti-freezing method for reservoir sampling points mainly relies on manual deicing, which is not only inefficient but also has safety risks. Among the existing water surface anti-freezing devices, generally, heating equipment is installed under the water surface to increase the water temperature and prevent the water surface from icing. Although it can prevent the water surface from icing to a certain extent, it requires manual control of the heating equipment according to the water temperature, and in addition, the continuous heating of the water body consumes a high amount of energy. Therefore, we propose a water surface anti-freezing device. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model discloses a water surface anti-freezing device, and the adopted technical solution is that it includes a fixed frame, a detection tube, a lifting unit and an anti-freezing unit. The fixed frame is in an "L" shape. A lifting unit is arranged at the rear side of the fixed frame, and the lifting unit is fixedly connected to the top of the detection tube arranged at the front side of the fixed frame. A plurality of air holes are equidistantly arranged in a circumferential array at the top outside of the detection tube. A connecting tube is communicated in the middle on the right side of the detection tube. A second fixing block is arranged at the bottom on the right side inside the connecting tube, and a liquid level sensor is fixedly installed on the second fixing block. A fixing plate is welded in the middle inside the connecting tube. A guide rod is fixedly installed at the left end of the bottom of the fixing plate. A sliding rod frame is fixedly installed on the left side inside the detection tube. A floating cylinder is arranged at the bottom between the sliding rod frame and the guide rod. The perforated sliders arranged at the top on the left and right sides of the floating cylinder are respectively slidably connected to the sliding rod frame and the guide rod. A first fixing block is arranged in the middle of the sliding rod frame, and a laser displacement sensor for detecting the moving distance of the floating cylinder is fixedly installed at the right end of the first fixing block. An anti-freezing unit is arranged between the detection tube and the connecting tube. The anti-freezing unit includes a second motor, a moving frame, a driving cylinder, a circulating guide groove and a push rod. The second motor is fixedly installed at the top of the connecting tube. The output shaft of the second motor passes through a through hole arranged at the center of the top of the connecting tube and is fixedly connected to the top of a fixed shaft arranged at the center of a driving cylinder arranged at the top inside the connecting tube. The bottom of the fixed shaft at the center of the driving cylinder is rotatably connected to the top of the fixing plate through a bearing. A circulating guide groove is arranged on the outside of the driving cylinder. A moving frame is slidably installed inside the circulating guide groove, and the left end of the moving frame is slidably connected to the sliding rod frame. A push rod for pushing the floating cylinder is welded at the center of the bottom of the moving frame.

[0005] As a preferred technical solution of the present utility model, the lifting unit includes a first motor, a through groove, a threaded rod, a slide rail and a lifting table. The first motor is fixedly installed on the extension plate arranged at the top of the rear side of the fixed frame. The output shaft of the first motor passes through the through hole arranged on the extension plate and is fixedly connected to the top of the threaded rod arranged at the rear side of the fixed frame. The bottom of the threaded rod is rotationally connected to the bottom of the rear side of the fixed frame through a bearing. A lifting table is threadedly installed on the threaded rod. The lifting table passes through the through groove arranged in the middle of the fixed frame and is slidably connected to the slide rails arranged at the left and right ends of the front side of the fixed frame. The front end of the lifting table is fixedly connected to the outer top of the detection tube. The design of the lifting unit enables the detection tube and the connecting tube to be conveniently moved vertically to adapt to reservoir sampling points at different depths. By driving the threaded rod to rotate through the first motor, the lifting table is driven to slide on the slide rails to achieve the lifting function.

[0006] As a preferred technical solution of the present utility model, the outer surfaces of the detection tube and the connecting tube are both coated with black epoxy resin paint. The coating of black epoxy resin paint can enhance the corrosion resistance of the detection tube and the connecting tube and improve their service life in harsh environments. At the same time, black epoxy resin paint can also absorb the heat of sunlight, which helps to maintain the temperature of the tube body in cold environments.

[0007] As a preferred technical solution of the present utility model, a water temperature sensor is fixedly installed at the bottom right side inside the connecting tube, and the water temperature sensor is located below the detection end of the liquid level sensor. Installing the water temperature sensor at the bottom right side inside the connecting tube and below the detection end of the liquid level sensor can ensure that the water temperature sensor is completely immersed in water, so as to more accurately detect the water temperature.

[0008] As a preferred technical solution of the present utility model, it further includes mounting holes. There are two mounting holes, and the mounting holes are symmetrically arranged on the left and right sides of the rear end of the fixed frame respectively. Through the mounting holes, bolts, expansion screws or other fixing parts can be used to firmly install the fixed frame in an appropriate position.

[0009] As a preferred technical solution of the present utility model, it further includes a controller. The controller is fixedly installed at the left end of the top of the rear side of the fixed frame. The output end of the controller is electrically connected to the input ends of the first motor and the second motor. The input end of the controller is electrically connected to the output ends of the laser displacement sensor, the liquid level sensor, the water temperature sensor and the external power supply. Through the setting of the controller, the staff can conveniently control the operation of the first motor and the second motor. At the same time, the controller can receive the signals of the laser displacement sensor, the liquid level sensor and the water temperature sensor in real time to realize the real-time monitoring of the water surface condition and the automatic control of the anti-freezing function.

[0010] Advantages of the present utility model: Through the design of the lifting unit, the present utility model realizes the automatic lifting of the detection tube and the connecting tube to adapt to reservoir sampling points at different depths, improving the flexibility and adaptability of the device. Through the design of the anti-freezing unit, the influence of water surface icing on the sampling work is effectively prevented. The anti-freezing unit uses the drive of the second motor to periodically push and press the floating drum through the moving frame and the push rod, disturbing the water surface and breaking the thin ice layer, thus ensuring the unobstructed sampling point and enabling normal sampling work even in cold seasons.

[0011] In addition, the laser displacement sensor can real-time monitor the displacement value of the floating drum, reflecting the current water surface situation. The liquid level sensor can ensure that the water temperature sensor is completely immersed in water for accurate water temperature detection. The water temperature sensor can real-time monitor the water temperature, enabling the controller to judge whether to start the anti-freezing unit.

[0012] In summary, through the design of the lifting unit and the anti-freezing unit, as well as the application of various sensors, the water surface anti-freezing device realizes the automatic detection of whether the water surface of the reservoir sampling point is frozen and effectively prevents the occurrence of water surface icing at the reservoir water quality sampling point.

Detailed Embodiments Embodiment 1

[0018] As Figures 1 to 4As shown in the figure, the utility model discloses a water surface antifreeze device. The technical solution adopted is as follows: it includes a fixing frame 1, a detection tube 2, a lifting unit 4 and an antifreeze unit 5. The fixing frame 1 is in an "L" shape structure and also includes two mounting holes 17. The mounting holes 17 are respectively arranged symmetrically left and right at the rear end of the fixing frame 1, which is convenient for fixing the fixing frame 1. A lifting unit 4 is arranged at the rear side of the fixing frame 1, and the lifting unit 4 is fixedly connected to the top of the detection tube 2 arranged at the front side of the fixing frame 1. The lifting unit 4 includes a first motor 41, a through groove 42, a threaded rod 43, a slide rail 44 and a lifting platform 45. The first motor 41 is fixedly installed on the extension plate arranged at the top of the rear side of the fixing frame 1. The output shaft of the first motor 41 passes through the through hole arranged on the extension plate and is fixedly connected to the top of the threaded rod 43 arranged at the rear side of the fixing frame 1. The bottom of the threaded rod 43 is rotationally connected to the bottom of the rear side of the fixing frame 1 through a bearing. A lifting platform 45 is threadedly installed on the threaded rod 43. The lifting platform 45 passes through the through groove 42 arranged in the middle of the fixing frame 1 and is slidably connected to the slide rails 44 arranged at the left and right ends of the front side of the fixing frame 1. The front end of the lifting platform 45 is fixedly connected to the outer top of the detection tube 2. By operating the first motor 41, the conveying shaft of the first motor 41 drives the threaded rod 43 to rotate. Since the threaded rod 43 is threadedly connected to the lifting platform 45, the rotation of the threaded rod 43 will drive the lifting platform 45 to move vertically along the slide rail 44. A number of ventilation holes 7 are arranged at equal distances in a circumferential array on the outer top of the detection tube 2. A connecting pipe 6 is communicated and arranged in the middle of the right side of the detection tube 2. A second fixing block 14 is arranged at the bottom right side inside the connecting pipe 6. A liquid level sensor 15 is fixedly installed on the second fixing block 14. A water temperature sensor 16 is fixedly installed at the bottom right side inside the connecting pipe 6, and the water temperature sensor 16 is located below the detection end of the liquid level sensor 15. By driving the detection tube 2 and the connecting pipe 6 to move through the lifting platform 45 and making the bottoms of the detection tube 2 and the connecting pipe 6 insert into the water until the water level reaches the liquid level value preset by the liquid level sensor 15, this ensures that the water temperature sensor 16 is completely immersed in the water to accurately detect the water temperature. The outer surfaces of both the detection tube 2 and the connecting pipe 6 are coated with black epoxy paint. A fixing plate 11 is welded and arranged in the middle of the inner side of the connecting pipe 6. A guide rod 10 is fixedly installed at the left end of the bottom of the fixing plate 11. A slide rod frame 8 is fixedly installed on the left side inside the detection tube 2. A floating cylinder 9 is arranged at the bottom between the slide rod frame 8 and the guide rod 10. The slider with holes arranged at the top of the left and right sides of the floating cylinder 9 is respectively slidably connected to the slide rod frame 8 and the guide rod 10. A first fixing block 12 is arranged in the middle of the slide rod frame 8. A laser displacement sensor 13 for detecting the moving distance of the floating cylinder 9 is fixedly installed at the right end of the first fixing block 12. An antifreeze unit 5 is arranged between the detection tube 2 and the connecting pipe 6. The antifreeze unit 5 includes a second motor 51, a moving frame 52, a driving cylinder 53, a circulating guide groove 54 and a push rod 55. The second motor 51 is fixedly installed at the top end of the connecting pipe 6,The output shaft of the second motor 51 passes through a through hole provided at the center of the top of the connecting pipe 6 and is fixedly connected to the top end of a fixed shaft provided at the center of the driving cylinder 53 provided on the inner top of the connecting pipe 6. The bottom of the fixed shaft at the center of the driving cylinder 53 is rotatably connected to the top of the fixed plate 11 through a bearing. A circulating guide groove 54 is provided on the outer side of the driving cylinder 53. A moving frame 52 is slidably installed inside the circulating guide groove 54. The left end of the moving frame 52 is slidably connected to the sliding rod frame 8. A push rod 55 for pushing the floating cylinder 9 is welded to the center of the bottom of the moving frame 52. By operating the second motor 51, its output shaft will drive the driving cylinder 53 to rotate. Since the moving frame 52 is slidably connected to the circulating guide groove 54 on the driving cylinder 53, the rotation of the driving cylinder 53 will cause the moving frame 52 to move along the circulating guide groove 54. At the same time, the other end of the moving frame 52 slides along the sliding rod frame 8. By repeatedly moving up and down the moving frame 52 along the circulating guide groove 54, the push rod 55 at the bottom of the moving frame 52 periodically presses the floating cylinder 9. The up and down movement of the floating cylinder 9 will disturb the water surface to a certain extent, thereby preventing the water surface from freezing. It further includes a controller 3. The controller 3 is fixedly installed at the left end of the top of the rear side of the fixed frame 1. The output end of the controller 3 is electrically connected to the input ends of the first motor 41 and the second motor 51. The input end of the controller 3 is electrically connected to the output ends of the laser displacement sensor 13, the liquid level sensor 15, the water temperature sensor 16, and an external power supply. The controller 3 can analyze the data detected by the laser displacement sensor 13, the liquid level sensor 15, and the water temperature sensor 16. When the floating value of the floating cylinder 9 monitored by the laser displacement sensor 13 is less than the set value range, and when the water temperature monitored by the water temperature sensor 16 is close to the freezing point, the controller 3 will activate the anti-freezing unit 5 to prevent the water surface at the reservoir sampling point from freezing.

[0019] Working principle of the utility model: When in use, first fix the fixing frame 1 at an appropriate position at the reservoir sampling point through the mounting hole 17. Then, start the first motor 41 through the controller 3, so that the output shaft of the first motor 41 drives the threaded rod 43 to rotate, thereby driving the lifting platform 45 to drive the detection tube 2 and the connecting tube 6 to move along the slide rail 44, so that the bottoms of the detection tube 2 and the connecting tube 6 are inserted into the water. Until the water submerges to the liquid level value preset by the liquid level sensor 15, thereby ensuring that the water temperature sensor 16 is completely immersed in the water for accurate water temperature detection. At the same time, since the top of the detection tube 2 is provided with a ventilation hole 7, when water enters the inside of the detection tube 2, the air inside the detection tube 2 is discharged from the ventilation hole 7. In addition, since the floating cylinder 9 itself has a certain buoyancy, the floating cylinder 9 will rise and fall with the water surface fluctuation, and thus slide up and down along the guide rod 10 and the slide rod frame 8. At this time, the laser displacement sensor 13 can monitor the displacement value of the floating cylinder 9 in real time. By monitoring the floating value of the floating cylinder 9, the current water surface condition can be reflected. When the floating value of the floating cylinder 9 is less than the set value range and the water temperature monitored by the water temperature sensor 16 is close to the freezing point, the controller 3 will start the antifreeze unit 5. By running the second motor 51, its output shaft will drive the driving cylinder 53 to rotate. Since the moving frame 52 is slidably connected to the circulating guide groove 54 on the driving cylinder 53, the rotation of the driving cylinder 53 will cause the moving frame 52 to move along the circulating guide groove 54. At the same time, the other end of the moving frame 52 slides along the slide rod frame 8. By the repeated up and down movement of the moving frame 52 along the circulating guide groove 54, the push rod 55 at the bottom of the moving frame 52 periodically presses the floating cylinder 9. The up and down movement of the floating cylinder 9 will disturb the water surface to a certain extent, thereby preventing the water surface from freezing, or enabling the floating cylinder 9 to easily break through the thin ice layer just formed on the water surface, thus avoiding the water surface at the reservoir sampling point from freezing and icing up.
