Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and particularly relates to an intelligent water quality detection sampling system with complementary fishing and photovoltaic Background Art

[0002] During the aquaculture process, maintaining a stable oxygen content in water is crucial for maintaining a healthy aquatic ecosystem. Generally, aerators and photovoltaic panels are used to promote the photosynthesis of algae to regulate the oxygen content in the aquaculture pond. Therefore, it is necessary to regularly sample the water to detect the oxygen content in the water, so as to be able to regulate the oxygen content in the aquaculture pond according to the actual situation.

A one-way valve 26 communicating with the inside of the sampling bottle is provided on the side surface of the sampling bottle. Through the settings of the first threaded hole, the second threaded hole, and the third threaded hole, when it is necessary to remove the sampling bottle after sampling, only by rotating the sampling bottle can the threadedly connected bottle mouth and threaded hole be separated, so that the sampling bottle can be easily removed for subsequent detection.

[0027] The driving device includes a vacuum pump 40 fixedly arranged on the support column 2. An air inlet hole 41 is arranged in the working rod 5, and the vacuum pump 40 is communicated with the air inlet hole 41 through an air vent hose 42.

[0028] The conversion device includes a movable groove 50 arranged in the working rod 5. A movable plate 51 that can reciprocate in a sealed manner is arranged in the movable groove 50. A through hole 52 is arranged in the movable plate 51. A first magnet 53 is fixedly arranged on the movable plate 51, and a second magnet 54 is fixedly arranged on the side wall of the movable groove 50. The side surfaces of the first magnet 53 and the second magnet 54 facing each other have the same polarity.

[0029] The conversion device further includes a first ventilation long groove 60 and a second ventilation long groove 61. One end of the first ventilation long groove 60 is communicated with the first pipeline 6, and the other end is communicated with the movable groove 50. One end of the second ventilation long groove 61 is communicated with the second pipeline 7, and the other end is communicated with the movable groove 50. A conversion part is arranged in each of the first ventilation long groove 60 and the second ventilation long groove 61. The conversion part includes a moving rod 62 arranged in the first pipeline 6. A piston block 63 capable of reciprocating movably in a sealed manner is fixedly arranged at one end of the moving rod 62 located in the first ventilation long groove 60. A return spring 660 (the return spring 660 is used for the piston block 63 to reset) is fixedly arranged between the piston block 63 and the first ventilation long groove 60. A floating ball 64 is fixedly arranged at the other end of the moving rod 62. A first push block 65 and a second push block 66 are arranged in the upper end of the first ventilation long groove 60.

A spring 167 (the spring 167 is used for the second push block 66 to reset) is fixedly arranged between the second push block 66 and the side wall of the first ventilation long groove 60.

[0030] When the three sampling bottles 25 are at different water levels in the pool, the vacuum pump 40 is started, and water is sucked into the sampling bottle 25 located under the first threaded hole 22 through the ventilation hose 42, the air inlet hole 41, the through hole 52, and the first pipe 6; when the water in the sampling bottle 25 reaches the preset water level, the water just pushes the float 64 upward, and the float 64 will drive the moving rod 62 and the piston block 63 upward, so that the distance between the piston block 63 and the first push block 65 is reduced, the air pressure increases, and the increased air pressure in the first ventilation long groove 60 pushes the first push block 65 to move. The first push block 65 will be pushed to drive the second push block 66 downward, and the second push block 66 will drive the stopper 67 downward. The stopper 67 no longer obstructs the movable plate 51. Therefore, under the action of the same-sex repulsion of the second magnet 54 and the first magnet 53, the first magnet 53 is pushed to drive the movable plate 51 to move, so that the through hole 52 moves above the second pipe 7 (that is, the through hole 52 is no longer connected to the first pipe 6, but is connected to the second pipe 7). Similarly, when the sampling bottle 25 located under the second threaded hole 23 takes water to the preset water level under the action of the vacuum pump, the water will also push the float 64 upward, so that the piston block 63 in the second ventilation long groove 61 moves upward, and the stopper 67 at one end in the second ventilation long groove 61 moves back into the second ventilation long groove 61, that is, the stopper 67 no longer obstructs the movable plate 51. Under the action of the same-sex repulsion of the second magnet 54 and the first magnet 53, the movable plate 51 continues to move, so that the through hole 52 reaches above the third pipe 8 (at this time, the through hole 52 is no longer connected to the second pipe 7, but is connected to the third pipe 8). When the sampling bottle 25 located under the third threaded hole 24 takes water to the preset water level under the action of the vacuum pump, the infrared water level sensor 800 will sense it, and thus the infrared water level sensor 800 will send a signal to turn off the vacuum pump 40.

[0031] A first inclined surface 68 is provided on the first push block 65, and a second inclined surface 69 matching the first inclined surface 68 is provided on the second push block 66.

[0032] Both the first magnet 53 and the second magnet 54 are made of neodymium iron boron magnets.

[0033] A roller 80 is rotatably provided at each of the four corners of the bottom surface of the base 1.

[0034] An infrared water level sensor 800 is fixedly provided inside the lower end of the third pipe 8, and the infrared water level sensor 800 faces the mouth of the sampling bottle 25. When the sampling bottle 25 located under the third threaded hole 24 takes water to the preset water level under the action of the vacuum pump, the infrared water level sensor 800 will sense it, and thus the infrared water level sensor 800 will send a signal to turn off the vacuum pump 40.

[0035] The working principle of the present invention includes the following processes:

[0036] When it is necessary to take a water sample from the aquaculture pond, only need to move the working rod 5 above the water surface in the pond to be sampled, and then start the rodless cylinder 3, let the rodless cylinder 3 drive the working rod 5 to move downward into the pond, so that the three sampling bottles 25 are located at different water levels in the pond. The vacuum pump 40 is started, and the water is sucked into the sampling bottle 25 under the first threaded hole 22 through the ventilation hose 42, the air inlet hole 41, the through hole 52, and the first pipe 6; when the water in the sampling bottle 25 reaches the preset water level, the water just pushes the float 64 to move upward, and the float 64 will drive the moving rod 62 and the piston block 63 to move upward, so that the distance between the piston block 63 and the first push block 65 is reduced, the air pressure increases, and the increased air pressure in the first ventilation long groove 60 pushes the first push block 65 to move. The first push block 65 will be pushed to drive the second push block 66 to move downward, and the second push block 66 will drive the stop block 67 to move downward. The stop block 67 no longer obstructs the movable plate 51. Therefore, under the action of the like-sex repulsion of the second magnet 54 and the first magnet 53, the first magnet 53 is pushed to drive the movable plate 51 to move, so that the through hole 52 moves above the second pipe 7 (that is, the through hole 52 is no longer connected to the first pipe 6, but is connected to the second pipe 7). Similarly, when the sampling bottle 25 under the second threaded hole 23 takes water to the preset water level under the action of the vacuum pump, the water will also push the float 64 to move upward, so that the piston block 63 in the second ventilation long groove 61 moves upward, and the stop block 67 at one end in the second ventilation long groove 61 moves back into the second ventilation long groove 61, that is, the stop block 67 no longer obstructs the movable plate 51. Under the action of the like-sex repulsion of the second magnet 54 and the first magnet 53, the movable plate 51 continues to move, so that the through hole 52 reaches above the third pipe 8 (at this time, the through hole 52 is no longer connected to the second pipe 7, but is connected to the third pipe 8). When the sampling bottle 25 under the third threaded hole 24 takes water to the preset water level under the action of the vacuum pump, the infrared water level sensor 800 will sense it, and then the infrared water level sensor 800 will send a signal to turn off the vacuum pump 40, so that the working rod 5 can complete the sampling of the three sampling bottles in one sampling operation, making the sampling work more convenient and fast.
