Description

Technical Field

[0001] The present invention relates to the technical field of hydrological measurement, and specifically relates to an intelligent water intake device for hydrological measurement and its method. Background Technique

[0002] With the implementation of the national marine development strategy, people have turned more and more attention to the ocean. The ocean contains rich mineral resources, marine biological resources and energy. Marine research is one of the research focuses of countries around the world. In order to obtain first-hand marine data, researchers need to sample and analyze seawater at different depths.

[0003] According to the patent: CN201911402889.5, a multi-stage marine water quality stratified sampling device and its sampling method, it can be known that the sampling device in this patent can be used to perform stratified sampling of seawater, with simple and convenient operation, which is conducive to the subsequent research of marine seawater resources. However, when sampling, the staff needs to use a lifting device to put the device into the seawater. By placing it in seawater at different depths, seawater at different layers can be sampled, which increases the workload of the staff. Moreover, when taking water at the same depth at different times, only the pressure difference can be used to judge whether a certain depth is reached, and it cannot be judged whether there is any deviation due to different seawater flows or other external factors when the sampling device is placed in the sea by the rope, which affects the sampling accuracy.

Detailed implementation manners

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figure 1-13 , the present invention provides a technical solution: a hydrological measurement intelligent water intake device 3 and its method, including the following steps:

[0048] Step 1: The staff first place the set seabed fixing device 1 at the position on the seabed where water needs to be taken.

[0049] Step 2: The lifting device 2 provided on the seabed fixing device 1 can drive the set water intake device 3 to rise and fall to different water layers inside the seabed to take water respectively.

[0050] Step 3: When the water intake is completed, the lifting device 2 can float to the water surface and release a signal, so that the staff can move to this position and use the lifting device 2 to lift the entire device from the seabed.

[0051] The set water intake device 3 can take water from different water layers at different times respectively, and when the lifting device 2 is in use, it can detect whether the lifting device 2 and the water intake device are tilted when sampling the same water layer at different times, and can correct the degree of this tilt. Therefore, when sampling, the position deviation of the water intake device when taking water from the same water layer is not much.

[0052] The seabed fixing device 1 includes a set support platform 10, and a lead block 11 is fixed at the bottom of the support platform 10. The weight of the lead block 11 is heavy enough. Its function is to firmly fix the entire system to prevent the device from moving due to the influence of ocean currents and avoid the support platform 10 from shifting on the seabed.

[0053] The lifting device 2 includes a support plate 20 provided on the top of the support platform 10. A plurality of rolling beads are fixed at the bottom of the support plate 20, which can make the support plate 20 move and adjust its position better on the support platform 10.

The correction device 4 includes an annular groove 40 provided on the support platform 10, and an annular gear 41 is rotatably connected to the inside of the annular groove 40 through a bearing. And a driving gear 42 is meshed with the outside of the annular gear 41. A driving motor 43 is fixed at the bottom of the driving gear 42, and the driving motor 43 is fixed inside the support platform 10 through a motor slot;

[0054] Two telescopic cylinders 44 are fixed to the top of the annular tooth 41, and the two telescopic cylinders 44 are coaxially arranged. An arc-shaped plate 45 capable of extruding the support plate 20 is fixed to the output end of the telescopic cylinder 44. When the telescopic cylinder 44 is opened, the telescopic cylinder 44 can drive the support plate 20 to move, and the position of the support plate 20 on the support table 10 can be adjusted. At the same time, driving the driving gear 42 and the annular tooth 41 to move through the driving motor 43 can drive the two telescopic cylinders 44 to rotate, so that the two telescopic cylinders 44 can drive the support plate 20 to move to positions in different directions;

[0055] A water sample tray 21 is fixed to the top of the support table 10. The shape of the water sample tray 21 can be set into any shape. A winch 22 is fixed to the support plate 20, and a moving device 5 capable of driving the winch 22 to move is arranged on the support plate 20. The moving device 5 includes a moving groove 50 arranged on the support plate 20. A moving block 51 is slidably connected inside the moving groove 50. The shapes of the moving block 51 and the moving groove 50 are both set as cross-shaped, which can make the moving block 51 more stable when moving, and the top of the moving block 51 is fixedly connected to the bottom of the winch 22;

[0056] A threaded rod 52 is threadedly sleeved on the top of the moving block 51, and both ends of the threaded rod 52 are rotatably connected to the top of the support plate 20 through bearings. Any one end of the threaded rod 52 is fixed with a rotating motor 53. The rotating motor 53 is arranged on the top of the support plate 20 through a motor groove, and a waterproof shell is arranged outside the rotating motor 53 to prevent the rotating motor 53 from getting water during use;

[0057] When the rotating motor 53 is turned on, the rotating motor 53 drives the threaded rod 52 to rotate. The threaded rod 52 drives the moving block 51 to move inside the moving groove 50, so that the moving block 51 can drive the winch 22 to move on the support plate 20, and thus the position of the winch 22 can be adjusted.

[0058] A lifting rope 23 is wound around the winch 22. A measuring device 6 capable of measuring the winding and unwinding length of the lifting rope 23 is arranged on the support plate 20. The measuring device 6 includes a main pulley 60 fixed to the support plate 20. An auxiliary pulley 61 is arranged outside the main pulley 60.

[0059] On both sides of the main pulley 60, corresponding light emitters 62 and light receivers 63 for calculating the number of rotations of the main pulley 60 are fixed. The light emitter 62 can rotate with the main pulley 60. When the hoist 22 contracts the lifting rope 23, the lifting rope 23 can move between the main pulley 60 and the auxiliary pulley 61. The lifting rope 23 can drive the main pulley 60 to rotate, and the rotation of the main pulley 60 drives the light emitter 62 to rotate. Thus, by the number of inductions between the light emitter 62 and the light receiver 63, the number of rotations of the main pulley 60 can be detected. Then, based on the number of rotations and the circumference of the main pulley 60, the length of the lifting rope 23 retracted and released can be calculated.

[0060] A communication groove 24 is provided at the center of the water sample tray 21. An annular pressure detector 25 is provided at the bottom of the communication groove 24.

The fixing device 7 includes electric telescopic rods 70 respectively fixed on both sides of the placement groove 28. The output ends of the electric telescopic rods 70 are fixed with clamping plates 71, and the two clamping plates 71 are staggered. A convex block 72 is provided on the outer side of the clamping plate 71. When the two clamping plates 71 fix the lifting rope 23, the lifting rope 23 can be fixed in a Z shape, so that the bottom of the lifting rope 23 can be fixed more stably. When the electric telescopic rod 70 is opened, the electric telescopic rod 70 can drive the two clamping plates 71 to fix the bottom of the lifting rope 23.

[0062] The top of the lifting rope 23 is connected to the water intake device 3, and the water intake device 3 is located at the bottom of the buoy 26;

[0063] A lithium battery 12 and a control board 13 are fixed on the support platform 10. Pressure detectors 14 for detecting the height difference are fixed on both the support platform 10 and the outside of the water intake device 3. The height of the water intake layer can be calculated through the values of the two pressure detectors 14.

[0064] The water intake device 3 includes a water intake tray 30 fixed to the top of the lifting rope 23 and corresponding to the water sample tray 21. The shape of the water intake tray can be set to any shape according to the water sample tray 21. A plurality of water intake grooves 31 are provided on the water intake tray 30, and sampling cups 32 are provided inside the water intake grooves 31;

[0065] A water intake port 33 is provided at the bottom of the sampling cup 32, and a cover plate 34 is provided outside the water intake port 33. A motor 35 is fixed on the outside of the cover plate 34, and the motor 35 is fixed to the bottom of the sampling cup 32 through a waterproof shell;

[0066] A clamping groove 36 is provided at the top of the sampling cup 32, a supporting device 37 is connected inside the clamping groove 36, and the supporting device 37 is connected to the top of the water intake tray 30.

[0067] The supporting device 37 includes a clamping rod 38 clamped inside the clamping groove 36. The shapes of the clamping rod 38 and the clamping groove 36 are both set to be cross-shaped, so that the clamping rod 38 and the clamping groove 36 are more stable when being clamped. A second motor 39 is fixed to the top of the clamping rod 38. The second motor 39 is fixed with a second electric telescopic rod 3a through a waterproof shell, and the second electric telescopic rod 3a is fixedly connected to the top of the water intake tray 30;

[0068] Turn on the first motor 35. The first motor 35 can drive the cover plate 34 to rotate, so that the sampling cup 32 can sample from inside the water intake 33. After sampling is completed, use the cover plate 34 to cover the water intake 33.

[0069] Balancing chains 8 are respectively fixed at the four corners of the water sample tray 21 and the four corners of the support platform 10, which is convenient for lifting the entire device from the seabed. Specific implementation method:

[0071] When it is necessary to sample different water layers, the water intake tray 30 can be lifted to different water layers for sampling through the lifting rope 23. When it is necessary to sample the same water layer at different times, the lifting rope 23 can be released to the length at the previous time in this water layer. At the same time, according to the two pressure detectors 14, it can be calculated whether the water intake tray 30 is at the height of the previous water intake. If the pressure detector 14 at the top is different, then according to the pressure-bearing situation of the annular detector, it can be detected in which direction the lifting rope 23 deviates. Then, the support plate 20 is driven by the telescopic cylinder 44 to move a certain distance in the direction opposite to the deviation, and then the lifting rope 23 is released until the value of the pressure detector 14 at the top is the same as the previous time. Repeating the steps can realize water intake from different water layers;

[0072] When the water sampling is completed, the lifting rope 23 can drive the buoy 26 to move to the water surface, the signal release device 27 is released, and at the same time, the bottom of the lifting rope 23 is fixed with the clamping plate 71. Then the top of the lifting rope 23 can be connected to the elevator on the ship, so that the entire device can be lifted. Then the second motor 39 is turned on, and the second motor 39 drives the clamping rod to rotate, so that the clamping rod 38 is not clamped with the clamping groove 36, and the sampling cup 32 can be removed. At the same time, during the water sampling process, the sampled sampling cup 32 can also be placed inside the water sample tray 21 for storage.
