Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and particularly to a water quality monitoring device with a protection structure. Background Art

[0002] During the process of aquaculture, it is necessary to monitor the water quality. Water quality monitoring is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status.

[0003] For example, a water quality monitoring device for aquaculture with the publication number of CN220137115U installs a column on the shore of the aquaculture pond. Through the moving block, connecting block and slider included in the sliding component, as well as the pulling steel cable and guiding steel cable, it is convenient to drive the moving box horizontally through the fixing frame under the action of the pulling motor and the first guiding wheel. Then, the moving box moves above different pond areas. Then, through the lifting motor, winding wheel and connecting wire, it is convenient to drive the detection head to move up and down, so as to detect at different depths in the water. And during the movement, the telescopic power cord can directly supply power to the lifting motor. Thus, it is impossible to check the power or replenish the power before each use. And after the detection, it is directly retracted to the shore, making the detection process relatively simple, with a short detection time and improved detection efficiency. However, in actual use, if the density of fish in aquaculture is large, during the fish farming process, the cultured fish may hit the monitoring device, and the monitoring structure cannot be protected. The impact of some larger-sized fish may cause damage to the monitoring device, and the steel cable cannot be protected either. After the fish hit, it may scratch the scales or heads of the fish, and the steel cable may be wound around the fins of the fish, which will cause harm to the fish itself. Especially when farming larger-sized fish, it will affect the health of the fish. If a protection structure is directly added, during the aquaculture process, it is necessary to adjust the detection depth. After adjusting the detection depth, the comprehensiveness of the protection cannot be guaranteed, and there are certain defects in use.

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

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For this water quality monitoring device with a protection structure, when monitoring the water quality, the monitoring depth can be controlled, and the float and the steel cable can be protected, which can reduce the impact force of fish, avoid damage to the overall structure, and avoid damage to the health of fish caused by fish impact, thus improving the practicability; 1. When monitoring water quality, the water quality is monitored through a detection head. The wire rope can be wound or unwound through a hoisting mechanism, so that the mounting frame can be driven to move up and down, and the monitoring depth can be adjusted. During the process of adjusting the depth, when the mounting plate descends, it drives the mounting frame to move downward. 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 unwound on the rotating shaft, and the rotation of the rotating shaft can drive the clockwork spring to deform. The wire rope can be protected by two groups of protective cloths to prevent fish from directly hitting the wire rope. During the rotation of the rotating shaft, the rotating rod can be driven to rotate through the cooperation of the first belt pulley and the second belt pulley. After the rotating rod rotates, the two mounting rods can be driven to rotate, so that the movable plate rotates in a circle, and then the column rod abuts against the protective cloth. The distance between the column rod and the rotating rod is much larger than the distance between the rotating rod and the protective cloth. Therefore, as the rotating rod rotates, the movable plate can be pushed to move through the protective cloth, so that the telescopic spring can be stretched. When adjusting the monitoring depth, the protective cloth can always protect the wire rope, avoiding dead corners in the protection of the underwater wire rope after the depth is adjusted. And when the protective cloth moves, the movable plate rotates in a circle and moves, which can cause water fluctuations. Through the water fluctuations, fish can be driven away, so that fish can be driven away in waters with a large breeding density. When adjusting the monitoring depth, the protective cloth moves, reducing the possibility of fish hitting the protective cloth and avoiding the impact and friction between the moving protective cloth and the fish, further reducing fish damage; 2. The float can be protected by the protective cloth between the fixed ring and the mounting ring to prevent fish from directly hitting the float and causing damage. Both the protective cloth and the protection cloth are polyester mesh cloth, which has good corrosion resistance and is convenient for water penetration. If a fish hits the protection cloth, it can push the fixed ring to move upward, so that the mounting block slides on the vertical rod, and the buffer spring can be compressed, so that the impact of the fish can be further buffered and the fish can be protected; 3. A filter net cover is arranged outside the detection head to prevent impurities in the water from adhering. Another hoisting mechanism can be added to wind and unwind the connection line between the detection head and the waterproof motor. When the filter net cover needs to be cleaned regularly, the waterproof motor is started 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 reciprocally through the sliding connection with the sliding groove on the movable frame. The movable frame slides on the limiting rod for limitation, and then the rack can be driven to move reciprocally. During the reciprocal movement of the rack, the rotating shaft is driven to rotate reciprocally through the meshing with the rotating gear. Then, the two swing rods can be driven to rotate reciprocally through the rotating rod. The cleaning rod is driven to rotate in a circle outside the filter net cover through the swing rod, so that the filter net cover can be cleaned to avoid excessive attachments on the surface of the filter net cover affecting the monitoring accuracy.

One end of the rotating shaft 202 passes through one of the positioning plates 201 and is sleeved with a clockwork spring 205 outside. The two ends of the clockwork spring 205 are respectively fixedly connected to the housing 204 and the rotating shaft 202; Fixing plates 206 are arranged below the two positioning plates 201. A rotating rod 207 is rotatably connected between the two fixing plates 206. The other end of the rotating shaft 202 passes through the other positioning plate 201 and is fixedly installed with a first pulley 208. One end of the rotating rod 207 passes through one of the fixing plates 206 and is fixedly installed with a second pulley 209.

[0028] Example 1: As Figures 1 - 8 shown, when monitoring water quality, the water quality is monitored by the detection head 107. The steel cable 103 can be wound or unwound by the hoisting mechanism 102, so that the mounting frame 104 can be driven to move up and down, and the monitoring depth can be adjusted. During the process of adjusting the depth, when the mounting plate 105 descends, it drives the mounting frame 110 to move down. Under the action of the counterweight 109, the downward movement of the mounting frame 110 can pull the protective cloth 203 to move, so that the protective cloth 203 is unwound on the rotating shaft 202. The rotation of the rotating shaft 202 can drive the hairspring 205 to deform. The two sets of protective cloth 203 can protect the steel cable 103 to prevent fish from directly hitting the steel cable 103. During the rotation of the rotating shaft 202, the rotating rod 207 can be driven to rotate through the cooperation of the first belt pulley 208 and the second belt pulley 209. 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, and then the column rod 215 abuts 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 through the protective cloth 203, so that the telescopic spring 213 can be stretched. When adjusting the monitoring depth, the protective cloth 203 can always protect the steel cable 103 to avoid dead corners in the protection of the underwater steel cable 103 after the depth is adjusted. And during the movement of the protective cloth 203, the movable plate 212 rotates in a circle and moves, which can cause water fluctuations. Through the water fluctuations, fish can be driven away, so that fish can be driven away in waters with a large breeding density. When adjusting the monitoring depth, the protective cloth 203 moves, reducing the possibility of fish hitting the protective cloth 203 and avoiding the impact and friction between the moving protective cloth 203 and the fish, further reducing fish damage.

[0029] The bottom of the float 1 is provided with an installation ring 216, and several groups of fixing plates 206 are fixedly connected to the installation ring 216. Moreover, several connecting plates 217 are fixedly installed on the outside of the installation ring 216. At the same time, several fixing rings 218 are fixedly installed on one side of the several connecting plates 217 away from the installation ring 216. Furthermore, a protective cloth 219 is fixedly installed between the several connecting plates 217; Two groups of support rods 220 are symmetrically installed on the top of the fixing ring 218. Moreover, on one side of the two groups of support rods 220 close to the float 1, installation blocks 221 are fixedly installed. And a vertical rod 222 is slidably connected inside the installation block 221. At the same time, fixing frames 223 are fixedly installed at both ends of the vertical rod 222. Moreover, the fixing frames 223 are fixedly connected to the float 1. And a buffer spring 224 is sleeved on the outside of the vertical rod 222 above the installation block 221. And the two ends of the buffer spring 224 are fixedly connected to the upper fixing frame 223 and the installation block 221 respectively.

[0030] Embodiment 2: As Figure 4 and Figure 9 shown, the protective cloth 219 between the fixing ring 218 and the installation ring 216 can protect the float 1, preventing fish from directly hitting the float 1 and causing damage. Both the protective cloth 203 and the protective cloth 219 are polyester mesh cloths, which have good corrosion resistance and are convenient for water penetration. If fish hit the protective cloth 219, it can push the fixing ring 218 to move upward, making the installation block 221 slide on the vertical rod 222, and the buffer spring 224 can be compressed, so as to further buffer the impact of fish and protect the fish.

[0031] The cleaning component 3 is arranged below the inner side of the installation frame 104; The cleaning component 3 includes a support plate 301 fixedly installed on the inner side of the installation frame 104. Moreover, a waterproof motor 302 is fixedly installed on the top of the support plate 301. And the output end of the waterproof motor 302 passes through the support plate 301 and is fixedly installed with a turntable 304. At the same time, the top center of the installation plate 105 is rotatably connected with a rotating shaft 305; One side of the bottom of the turntable 304 is fixedly installed with a column block 306. And an activity frame 307 is arranged at the bottom of the turntable 304. Moreover, a sealing shell 303 is fixedly installed at the bottom of the support plate 301. At the same time, limiting rods 308 are symmetrically installed inside the sealing shell 303. And the activity frame 307 is slidably connected with the two limiting rods 308. And a sliding groove 3071 is opened at the top of the activity frame 307. And the column block 306 is slidably connected with the sliding groove 3071. At the same time, one side of the bottom of the activity frame 307 is fixedly installed with a rack 309 through a connecting block. And a rotating gear 310 is fixedly installed at the top of the rotating shaft 305. And the rotating gear 310 is meshed with the rack 309; The rotating shaft 305 is rotatably connected to the sealing housing 303. Symmetrically mounted outside the rotating shaft 305 and below the sealing housing 303 are rotating rods 311. Fixedly mounted at the ends of the two rotating rods 311 away from each other are swing rods 312. On both sides of the top of the mounting plate 105 and below the mounting frame 104, arc-shaped grooves 313 are symmetrically formed through. The swing rods 312 are slidably connected to the arc-shaped grooves 313. Fixedly mounted at the bottoms of the two swing rods 312 are cleaning rods 314.

[0032] Embodiment 3: As Figures 2 - 3 and Figure 10 shown, a filter mesh cover 106 is provided outside the detection head 107 to prevent impurities in the water from adhering. A hoisting mechanism 102 can be additionally provided to wind and unwind the connection line between the detection head 107 and the waterproof motor 302. When the filter mesh cover 106 needs to be cleaned regularly, the waterproof motor 302 is started to drive the turntable 304 to rotate, so that the column block 306 rotates in a circle. After the column block 306 rotates in a circle, it can drive the movable frame 307 to reciprocate through the sliding connection with the sliding groove 3071 on the movable frame 307. The movable frame 307 slides on the limiting rod 308 for limiting, and then can drive the rack 309 to reciprocate. During the reciprocating movement of the rack 309, it drives the rotating shaft 305 to rotate reciprocally through the meshing with the rotating gear 310. Then, the two swing rods 312 can be driven to rotate reciprocally through the rotating rods 311. The cleaning rods 314 are driven by the swing rods 312 to rotate in a circle outside the filter mesh cover 106, and the filter mesh cover 106 can be cleaned to prevent excessive attachments on the surface of the filter mesh cover 106 from affecting the monitoring accuracy.

[0033] Working principle: When using this loss-reducing explosion-proof and pressure-relieving transformer, first, according to Figures 1 - 10As shown in the figure, when monitoring water quality, the water quality is monitored through the detection head 107. The wire rope 103 can be wound or unwound through the hoisting mechanism 102, so that the mounting frame 104 can be driven to move up and down, and the monitoring depth can be adjusted. During the process of adjusting the depth, when the mounting plate 105 descends, it drives the mounting frame 110 to move downward. Under the action of the counterweight 109, the downward movement of the mounting frame 110 can pull the protective cloth 203 to move, so that the protective cloth 203 is unwound on the rotating shaft 202, and the rotation of the rotating shaft 202 can drive the clockwork spring 205 to deform. The wire rope 103 can be protected by two groups of protective cloth 203 to prevent fish from directly hitting the wire rope 103. During the rotation of the rotating shaft 202, the rotating rod 207 can be driven to rotate through the cooperation of the first pulley 208 and the second pulley 209. After the rotating rod 207 rotates, it can drive two groups of mounting rods 211 to rotate, so that the movable plate 212 rotates in a circle, and then the column rod 215 abuts 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. Therefore, as the rotating rod 207 rotates, the movable plate 212 can be pushed to move through the protective cloth 203, so that the telescopic spring 213 can be stretched. When adjusting the monitoring depth, the protective cloth 203 can always protect the wire rope 103, avoiding dead corners in the protection of the underwater wire rope 103 after the depth adjustment. And when the protective cloth 203 moves, the movable plate 212 rotates in a circle and moves, which can cause water fluctuations; The float 1 can be protected by the protective cloth 219 between the fixing ring 218 and the mounting ring 216, preventing direct impact of fish on the float 1 and causing damage. Both the protective cloth 203 and the protective cloth 219 are polyester mesh cloths, which have good corrosion resistance and are convenient for water permeability. If a fish hits the protective cloth 219, it can push the fixing ring 218 to move upward, so that the mounting block 221 slides on the vertical rod 222, and the buffer spring 224 can be compressed, further buffering the impact of the fish and protecting the fish. A filter mesh cover 106 is arranged outside the detection head 107 to prevent impurities in the water from attaching. A winch mechanism 102 can be additionally provided to wind and unwind the connection line between the detection head 107 and the waterproof motor 302. When the filter mesh cover 106 needs to be cleaned regularly, the waterproof motor 302 is started to drive the turntable 304 to rotate, so that the column block 306 rotates in a circle. After the column block 306 rotates in a circle, it can drive the movable frame 307 to move reciprocally through the sliding connection with the sliding groove 3071 on the movable frame 307. The movable frame 307 slides on the limiting rod 308 for limiting, and then can drive the rack 309 to move reciprocally. During the reciprocal movement of the rack 309, it drives the rotating shaft 305 to rotate reciprocally through the engagement with the rotating gear 310. Then, the two swing rods 312 can be driven to rotate reciprocally through the rotating rod 311.
