Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, in particular to a water quality monitoring device with a protective structure. Background Art

[0002] Water quality needs to be monitored during the aquaculture process. Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water, the concentrations of various pollutants and their changing trends, and evaluating the water quality conditions.

[0003] For example, an aquaculture water quality monitoring device with announcement number CN220137115U is a device that installs a column on the bank of an aquaculture pool, and uses a moving block, a connecting block and a slider, as well as a pulling cable and a guide cable included in the sliding assembly to facilitate driving the moving box in the horizontal direction through the fixed frame under the action of the pulling motor and the first guide wheel, so that the moving box moves above different pool areas, and then drives the detection head to move up and down through the lifting motor, the winding wheel and the connecting line, so that it can be tested in water of different depths, and the lifting motor can be directly powered by the retractable power cord during the movement, so that it is impossible to check or replenish the power before each use, and it is directly retracted to the shore after the detection contact, so that The detection process is relatively simple and the detection time is short, which improves the detection efficiency. However, in actual use, if the fish density in aquaculture is high, the farmed fish may collide with the monitoring device during the fish farming process, and the monitoring structure cannot be protected. The collision of some larger fish may cause damage to the monitoring device, and the steel cable cannot be protected. After the fish collide, the scales or head of the fish may be scratched, and the steel cable may be entangled in the fins of the fish, causing harm to the fish itself, especially when farming larger fish, affecting the health of the fish. If a protective structure is directly added, the monitoring depth needs to be adjusted during the aquaculture process. After adjusting the monitoring depth, the comprehensiveness of the protection cannot be guaranteed, and there are certain usage defects.

[0004] Therefore, we propose a water quality monitoring device with a protective structure to solve the above problems. Summary of the Invention

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: the water quality monitoring device with a protective structure can control the monitoring depth when monitoring water quality, and can protect the float and the steel cable, thereby reducing the impact force of fish, avoiding damage to the overall structure, and preventing fish impact from damaging the health of fish, thereby improving practicality;

[0029] 1. When monitoring water quality, the detection head is used to monitor water quality, and the winch mechanism can be used to reel in or unreel the steel cable, so that the mounting frame can be driven to move up and down, and the monitoring depth can be adjusted. In the process of adjusting the depth, the mounting plate drives the mounting frame downward when it descends. Under the action of the counterweight, the downward movement of the mounting frame can pull the protective cloth to move, so that the protective cloth is unreeled on the rotating shaft, and the rotation of the rotating shaft can drive the clockwork spring to deform. The steel cable can be protected by two sets of protective cloths to prevent fish from directly hitting the steel cable. During the rotation process, the rotating shaft can drive the rotating rod to rotate through the cooperation of the first pulley and the second pulley. After the rotating rod rotates, it can drive the two sets of mounting rods to rotate, so that the movable plate rotates in a circle, thereby making the column rod and The protective cloth is in contact with the rotating rod, and the distance between the column and the rotating rod is much larger than the distance between the rotating rod and the protective cloth. Then, as the rotating rod rotates, the protective cloth can push the movable plate to move, so that the telescopic spring can be stretched, so that when the monitoring depth is adjusted, the protective cloth can always protect the steel cable, avoiding the existence of a blind spot in the protection of the underwater steel cable after the depth is adjusted, and the movable plate moves in a circle during the movement of the protective cloth, which can cause water to fluctuate, and the fish can be driven away by the fluctuation of the water, so that fish can be driven away in waters with a high aquaculture density. When the monitoring depth is adjusted, the protective cloth moves, reducing the possibility of fish hitting the protective cloth, avoiding the collision and friction between the protective cloth and the fish, and further reducing the damage to the fish.

[0030] 2. The protective cloth between the fixing ring and the mounting ring can protect the float to prevent fish from directly hitting the float and causing damage. Both the protective cloth and the protective cloth are polyester mesh, which has good corrosion resistance and is easy to be water-permeable. If the fish hits the protective cloth, it can push the fixing ring to move upward, so that the mounting block slides on the vertical pole, which can compress the buffer spring, so that the impact of the fish can be further buffered and protected;

[0031] 3. A filter screen is set outside the detection head to prevent impurities from adhering to the water. A winch mechanism can be added to reel in and out the connecting line between the detection head and the waterproof motor. When the filter screen needs to be cleaned regularly, start the waterproof motor to drive the turntable to rotate, so that the column block rotates in a circle. After the column block rotates in a circle, the movable frame can be driven to move back and forth through the sliding connection with the sliding groove on the movable frame. The movable frame slides on the limit rod to limit the position, and then drives the rack to move back and forth. During the reciprocating movement of the rack, the rotating shaft is driven to rotate back and forth through the engagement with the rotating gear. After that, the two swing rods can be driven to rotate back and forth by the rotating rod. The cleaning rod is driven by the swing rod to rotate in a circle on the outside of the filter screen, so as to clean the filter screen and avoid excessive attachments on the surface of the filter screen that affect the monitoring accuracy.

[0061] Working principle: When using this loss-reducing explosion-proof pressure relief transformer, first, according to Figures 1-10 As shown, when monitoring the water quality, the detection head 107 is used to monitor the water quality, and the winch mechanism 102 can be used to reel in or unreel the steel cable 103, so that the mounting frame 104 can be driven to move up and down, and the monitoring depth can be adjusted. In the process of adjusting the depth, the mounting plate 105 is lowered and the mounting frame 110 is driven to move down. Under the action of the counterweight block 109, the downward movement of the mounting frame 110 can pull the protective cloth 203 to move, so that the protective cloth 203 is unreeled on the rotating shaft 202, and the rotation of the rotating shaft 202 can drive the clockwork spring 205 to deform. The steel cable 103 can be protected by two sets of protective cloths 203 to prevent fish from directly hitting the steel cable 103. The rotating shaft 202 can rotate through the first pulley 208 and the second pulley 20 9, the cooperation drives the rotating rod 207 to rotate. After the rotating rod 207 rotates, it can drive the two sets of mounting rods 211 to rotate, so that the movable plate 212 rotates in a circle, thereby making the column rod 215 abut against the protective cloth 203. The distance between the column rod 215 and the rotating rod 207 is much larger than the distance between the rotating rod 207 and the protective cloth 203. Then, as the rotating rod 207 rotates, the movable plate 212 can be pushed to move by the protective cloth 203, so that the telescopic spring 213 can be stretched, so that when adjusting the monitoring depth, the protective cloth 203 can always protect the steel cable 103, avoiding the existence of a blind spot in the protection of the underwater steel cable 103 after the depth adjustment, and the movable plate 212 moves in a circle during the movement of the protective cloth 203, which can cause water fluctuations.

[0062] The protective cloth 219 between the fixing ring 218 and the mounting ring 216 can protect the float 1 to prevent fish from directly hitting the float 1 and causing damage. The protective cloth 203 and the protective cloth 219 are both polyester mesh fabrics with good corrosion resistance and are easy to be water-permeable. If a fish hits the protective cloth 219, the fixing ring 218 can be pushed upward to make the mounting block 221 slide on the vertical pole 222, and the buffer spring 224 can be compressed to further buffer the impact of the fish and protect the fish. A filter screen cover 106 is set outside the detection head 107 to prevent impurities in the water from adhering. A hoisting mechanism 102 can be added to reel in and out the connecting line between the detection head 107 and the waterproof motor 302. When the filter screen cover 106 needs to be cleaned regularly, the waterproof The motor 302 drives the turntable 304 to rotate, causing the column block 306 to rotate in a circle. After the column block 306 rotates in a circle, it can drive the movable frame 307 to move back and forth through the sliding connection with the sliding groove 3071 on the movable frame 307. The movable frame 307 slides on the limit rod 308 to be limited, and then can drive the rack 309 to move back and forth.
