Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and in particular to an anti-interference buoy device for water quality detection and a detection method thereof. Background Art

[0002] As the importance of water resource protection and environmental monitoring becomes increasingly prominent, accurate detection of water quality becomes crucial. When conducting water quality detection, buoy devices are widely used due to their flexibility and the ability to be deployed in different waters. Buoy devices are small water quality monitoring devices placed in waters and are set up in automatic water quality monitoring laboratories in river and lake basins, with water quality monitors or instrument platforms as the core, using sensor technology, combined with buoy bodies and data transmission equipment.

[0003] Existing buoy devices lack adaptability when dealing with complex environmental changes. When there is a large fluctuation on the water surface or in windy weather conditions, the buoy cannot maintain a stable working state, affecting the continuity of water quality detection. In areas with strong winds and waves, a large force will be exerted on the buoy, causing the internal sensor components to shake violently. The direct impact of wind and waves will affect the measurement precision and accuracy of the sensor. For buoys with a higher center of gravity, there is also the problem of being blown over and capsized by strong winds and waves. At the same time, the sensor is also easily affected by external electromagnetic interference, resulting in low stability of measurement data transmission and low measurement accuracy of the sensor.

[0041] A method for detecting an anti-interference buoy device for water quality detection comprises the following steps:

[0042] Step 1: Place the buoy body 1 on the plane of the water area to be tested, and the buoy body 1 detects the water quality through the detector 3 at the bottom;

[0043] Step 2: When the horizontal surface has a large floating and the wind blows the buoy body 1, the bidirectional motor 6 fixed by the fixing plate 10 in the cavity 2 opened inside the buoy body 1 is started, and the bidirectional motor 6 drives the ball screw 71 at one end to rotate, so that the sleeve 72 slides downward on the slide bar 74 through the protrusion 73, lowering the center of gravity of the buoy body 1 to prevent it from tipping over, and at the same time drives the pull rope 79 to pull the rotating rod 76 to make the rotating plate 1 77 and the rotating plate 2 78 connected with reverse threads on the surface rotate in the opposite direction to form a V shape, so as to buffer the wind and waves below;

[0044] Step 3: The bevel gear 1 81 at the other end is driven to mesh with the bevel gear 2 82 through the bidirectional motor 6, so that the screw 1 84 drives the moving column 812 to move horizontally, and the floating block 1 89 and the floating block 2 811 are driven to move toward the outer end of the buoy body 1 through the connecting plate 1 88 and the connecting plate 2 810 respectively, so as to form a reaction force buffer for the horizontal wave force;

[0045] Step 4: The bevel gear 1 81 meshes with the bevel gear 3 91 to rotate, driving the screw 2 93 to move the push column 94, and the push column 94 drives the metal side plate 97 to move toward the sensor assembly 4. The output end of the cylinder 98 on one side of the metal side plate 97 is squeezed by the side of the metal top plate 5. The gas in the cylinder 98 is input into the airbag 910 to bulge, and the bulging airbag 910 contacts and fits with the sensor assembly 4 to provide a buffer for the sensor assembly 4. At the same time, the metal top plate 5 and the metal side plates 97 on both sides form a closed space to block electromagnetic interference, thereby improving the accuracy and reliability of water quality detection.

[0046] Specifically, when in use, the buoy body 1 detects the water quality through the detector 3 at the bottom. When the horizontal plane floats greatly and there is a strong wind force blowing the buoy body 1, the data transmitted by the sensor is output to the remote controller to start the bidirectional motor 6 fixed by the fixing plate 10 in the cavity 2 opened in the buoy body 1. The bidirectional motor 6 drives the ball screw 71 at one end to be threadedly connected with the sleeve 72. The sleeve 72 slides on the slide bar 74 through a protrusion 73 set on one side. One end of the slide bar 74 is connected to the fixing plate 10, so that the sleeve 72 moves downward to prevent the buoy body 1 from being blown to the side. As the sleeve 72 moves downward, the pull rope 79 is pulled, and one end of the pull rope 79 is connected to the fixing plate 10. The other end of the pull rope 79 is circled multiple times on the surface of the rotating rod 76. The rotating rod 76 is set at both ends. There is a clockwork spring 711, a rotating rod 76 is rotatably connected with the storage groove 75, a drawstring 79 wound multiple times on the surface of the rotating rod 76 is stretched, and the drawstring 79 is guided by a guide wheel 710, and the guide wheel 710 is rotatably connected with the storage groove 75, so that the rotating rod 76 rotates to drive the rotating plate 1 77 and the rotating plate 2 78 connected with the reverse thread on the surface to rotate in the opposite direction and tilt in a V shape, which has a certain buffering effect on wind and waves, and the downward movement of the sleeve 72 can lower the center of gravity of the buoy body 1, enhance the stability of the buoy body 1 in the water, and effectively prevent it from being blown over by the wind, which is very important for ensuring the normal operation of the buoy body 1 and detecting water quality in harsh environments, ensuring the continuity and reliability of the detection data, and being able to adjust the stability of the buoy body 1 in time according to the actual situation, thereby improving the adaptability of the buoy body 1 to different environmental conditions;

[0047] At the same time, the bidirectional motor 6 drives the bevel gear 1 81 at the other end to mesh with the bevel gear 2 82, and the bevel gear 2 82 drives the screw 1 84 on one side to be threadedly connected with the moving column 812. The bevel gear 2 82 is connected to the fixed plate 10 through the sleeve plate 83 on one side, and the sleeve plate 83 is rotatably connected to the screw 1 84. The moving column 812 slides on the long rod 85 through the circular plate 87 on the surface, and the long rod 85 is connected to the fixed plate 10 through the side plate 86. Since the outer end of the middle of the moving column 812 is connected to the fixed plate 10 through the connecting plate 1 88 is connected to the floating block 1 89, and the end of the moving column 812 away from the circular plate 87 is connected to the floating block 2 811 through the connecting plate 2 810, so that when the moving column 812 moves horizontally outward, it drives the floating block 1 89 and the floating block 2 811 to move toward the outer end of the buoy body 1, so that the floating block 1 89 and the floating block 2 811 use the wave force on the horizontal plane as a reaction force to form a buffer, which can effectively reduce the impact of waves on the buoy body 1 in the horizontal direction and improve the stability of the buoy body 1;

[0048] The bevel gear 1 81 meshes and rotates with the bevel gear 3 91 on the other side, and the bevel gear 3 91 drives the screw 2 93 to be screwed to the push column 94. One side of the bevel gear 3 91 is connected to the fixed plate 10 through the vertical plate 92, and the screw 2 93 is rotatably connected to the vertical plate 92. The push column 94 drives the driven block 95 on the surface to slide on the round rod 96. One end of the round rod 96 is fixedly connected to the vertical plate 92. The push column 94 drives the metal side plate 97 on one side to move toward the sensor assembly 4, so that the output end of the cylinder 98 protruding on one side of the metal side plate 97 is squeezed by the side of the metal top plate 5, and the gas inside the cylinder 98 is input into the gas through the gas pipe 99. Inside the airbag 910, the airbag 910 bulges, a spring 911 is arranged inside the airbag 910, one side of the airbag 910 is fixed inside the groove 912 opened on the surface of the metal side plate 97, the airbag 910 bulges and contacts and fits with the sensor assembly 4, and further the airbag 910 provides a buffer for the sensor assembly 4, which can effectively reduce the influence of external vibration and impact on the sensor assembly 4, and protect the normal operation of the sensor assembly 4.
