Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to water quality monitoring equipment. Background Art

[0002] Aquaculture is the use of waters available for breeding by humans, in accordance with the ecological habits of the breeding objects and the requirements for the water environment conditions, using aquaculture techniques and facilities to engage in the breeding of aquatic economic animals and plants.

[0003] For example, an agricultural aquaculture water quality monitoring device with publication number CN115290843B pulls the bottom end of the base frame while pulling the inner bottom of the protective film by moving the ring plate downward. The protective film gradually unfolds under the pulling of the ring plate, and the entire flat protective film gradually unfolds into an annular protective film. The protective frame is protected by the protective film with an annular structure. When external fish impact the protective film, the protective film itself can absorb part of the impact force, and the remaining impact force acts on the connecting rod through the protective film. At this time, the impact force received by the connecting rod passes through the top frame and the bottom frame to make the ring plate move down on the surface of the protective frame, and the ring plate uses the support rod to make the pressure plate and the slide rod squeeze the spring, and uses the spring to further absorb the remaining impact force, so as to avoid the impact force of the fish directly acting on the protective frame, thereby improving the protection of the protective frame. However, in actual use, while monitoring the water quality, there will be some impurities, algae, microorganisms, etc. in the water. The detection head is prone to adhere to impurities on the surface during the monitoring process, which will reduce the monitoring accuracy and make it inconvenient to clean the detection head. After long-term use, the monitoring accuracy is reduced, and there are certain usage defects.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the water quality monitoring device is provided with cleaning components under and on one side of the movable plate. During the aquaculture process, the detection head can monitor water samples of different depths while detecting the water quality. When adjusting the monitoring depth, the detection head can be better cleaned, thereby reducing the adhesion of impurities on the detection head, so that the accuracy of the detection head can be improved; 1. Cleaning components are set under and on one side of the movable plate. In the process of aquaculture, the water samples at different depths have different temperatures, dissolved oxygen, pH values, etc. When monitoring water samples at different depths, the multi-stage electric push rod is started to drive the movable plate to move. The movable plate moves and slides on the guide rod to limit the position, so that the position of the detection head can be adjusted. When the movable plate moves, the meshing of the rotating gear and the rack can drive the rotating shaft to rotate. After the rotating shaft rotates, the meshing of the first bevel gear and the second bevel gear can drive the rotating rod to rotate on the positioning frame. After the rotating rod rotates, the driven gear is engaged with the gear. The meshing of the teeth on the rotating ring can drive the rotating ring to rotate. After the rotating ring rotates, it can drive the limit ring to slide on the limit ring groove for limiting, and then drive the two L-shaped rods to rotate in a circle. The L-shaped silicone strip is relatively soft and can clean the detection head. Impurities are not easy to adhere to the L-shaped silicone strip. Through the cleaning component, the detection head can monitor water samples of different depths while detecting water quality. When adjusting the monitoring depth, the detection head can be better cleaned, thereby reducing the adhesion of impurities on the detection head, so that the accuracy of the detection head can be improved; 2. The rotating ring can push the sliding rod to move through the sliding groove while rotating. No matter whether the rotating ring rotates counterclockwise or clockwise, the sliding rod can be pushed to move close to the detection head. After the sliding rod moves, it can drive the L-shaped rod to move. The L-shaped rod is guided by the push rod when it moves. The push rod is tilted on the rotating ring, so that the sliding rod can push the L-shaped rod to move obliquely upward while moving toward the detection head, so that the L-shaped silicone strip can fit the side wall and bottom surface of the detection head at the same time. The detection head can be fully cleaned when the rotating ring and the rotating ring are rotated, and the push rod can compress the telescopic spring during the movement, so that after the movable plate stops moving, the push rod can automatically reset, so that the L-shaped rod can move obliquely downward, so that the L-shaped silicone strip no longer contacts the side wall and bottom surface of the detection head, so that when it is not cleaned, the L-shaped silicone strip will not block the detection head, avoiding affecting normal monitoring and ensuring normal signal transmission during detection; 3. When cleaning the detection head, the rotating ring can drive the L-shaped rod to rotate in a circle, so that the rotating ring rotates. When the rotating ring rotates, the protrusion can push the limit rod to move, so that the ball rotates on the protrusion. When the limit rod slides on the support frame, the reset spring can be stretched. When the ball does not contact the protrusion, the reset spring restores its deformation, so that the limit rod is reset, so that the rotating ring rotates while driving several protrusions to rotate. The limit rod can increase the resistance to the rotation of the rotating ring, thereby preventing the L-shaped rod from rotating in a circle without moving when the rotating ring drives the rotating ring and the L-shaped rod to move. By increasing the resistance, the rotating ring can first drive the L-shaped rod to move, and then drive the rotating ring to rotate, thereby preventing the L-shaped silicone strip from contacting the detection head.

During aquaculture, the water samples at different depths have different temperatures, dissolved oxygen, pH values, etc. When monitoring the water samples at different depths, the multi-stage electric push rod 103 is started to drive the movable plate 105 to move. The movable plate 105 moves and slides on the guide rod 108 to limit the position, so that the position of the detection head 106 can be adjusted. When the movable plate 105 moves, the meshing of the rotating gear 203 and the rack 205 can drive the rotating shaft 202 to rotate. After the rotating shaft 202 rotates, the meshing of the first bevel gear 208 and the second bevel gear 209 can drive the rotating rod 207 to rotate on the positioning frame 206. After the rotating rod 207 rotates, the driven gear 2 10 The rotating ring 211 can be driven to rotate by meshing with the teeth 212 on the rotating ring 211. After the rotating ring 211 rotates, the limiting ring 213 can be driven to slide on the limiting ring groove 2131 for limiting, thereby driving the two L-shaped rods 214 to rotate in a circle. The L-shaped silicone strip 215 is relatively soft and can be used to clean the detection head 106, and impurities are not easy to adhere to the L-shaped silicone strip 215. Through the cleaning component 2, the detection head 106 can monitor water samples of different depths while detecting water quality. When adjusting the monitoring depth, the detection head 106 can be better cleaned, thereby reducing the adhesion of impurities on the detection head 106, so that the accuracy of the detection head 106 can be improved.

[0027] A movable groove 2141 is formed on the upper part of the two L-shaped rods 214, and a sliding rod 2142 is slidably connected to the movable groove 2141. A sliding groove 2111 is symmetrically installed on the bottom of the rotating ring 211, and the sliding rod 2142 is slidably connected to the sliding groove 2111. A T-shaped ring groove 217 is provided at the top of the rotating ring 216, and two groups of arc blocks 218 are symmetrically rotated and connected inside the T-shaped ring groove 217, and the tops of the two groups of arc blocks 218 are fixedly installed with connecting blocks 219, and the tops of the connecting blocks 219 are fixedly installed with fixing rods 220, and the tops of the fixing rods 220 are fixedly connected to the movable plate 105; Mounting sleeves 221 are symmetrically installed on the lower sides of the outer side of the rotating ring 216, and push rods 222 are slidably connected to the inside of the two mounting sleeves 221, and the push rods 222 are slidably connected to the rotating ring 216. At the same time, one end of the two push rods 222 are fixedly connected to the two L-shaped rods 214 respectively, and a telescopic spring 223 is sleeved on the outer bottom of the two push rods 222, and one end of the telescopic spring 223 is fixedly connected to the mounting sleeve 221, and the other end of the telescopic spring 223 is fixedly connected to the push rod 222.

[0028] Embodiment 2: Figure 2 and Figure 6-Figure 10 As shown, the rotating ring 211 can push the sliding rod 2142 to move through the sliding groove 2111 while rotating. No matter whether the rotating ring 211 rotates counterclockwise or clockwise, the sliding rod 2142 can be pushed to move close to the detection head 106. After the sliding rod 2142 moves, it can drive the L-shaped rod 214 to move. When the L-shaped rod 214 moves, it is guided by the push rod 222. The push rod 222 is tilted on the rotating ring 216, so that the sliding rod 2142 can push the L-shaped rod 214 to move obliquely upward while moving toward the detection head 106, so that the L-shaped silicone strip 215 is simultaneously with the detection head 106. The side wall and bottom surface of the probe 106 are fitted together, and the rotating ring 211 and the rotating ring 216 are rotated to fully clean the detection head 106, and the push rod 222 can compress the telescopic spring 223 during the movement, so that after the movable plate 105 stops moving, the push rod 222 can automatically reset, and then the L-shaped rod 214 can move obliquely downward, so that the L-shaped silicone strip 215 no longer contacts the side wall and bottom surface of the detection head 106, and then when not cleaned, the L-shaped silicone strip 215 will not block the detection head 106, avoid affecting normal monitoring, and ensure normal signal transmission during detection.

[0029] A support frame 224 is fixedly installed on the side of the bottom of the movable plate 105 away from the mounting frame 201, and a limiting rod 225 is slidably connected to the inner lower part of the support frame 224, and a ball 226 is provided on the inner side of the limiting rod 225. At the same time, a plurality of protrusions 227 are fixedly installed on the outer upper part of the rotating ring 216, and the ball 226 is rotatably connected to the plurality of protrusions 227, and a return spring 228 is sleeved on the outer side of the limiting rod 225, and one end of the return spring 228 is fixedly connected to the support frame 224, and the other end of the return spring 228 is fixedly connected to the limiting rod 225.

[0030] Embodiment 3: Figure 2 and Figure 10-11As shown, when cleaning the detection head 106, the rotating ring 211 can drive the L-shaped rod 214 to rotate in a circle, so that the rotating ring 216 rotates. When the rotating ring 216 rotates, the protrusion 227 can push the limiting rod 225 to move, so that the ball 226 rotates on the protrusion 227. When the limiting rod 225 slides on the support frame 224, the reset spring 228 can be stretched. When the ball 226 does not contact the protrusion 227, the reset spring 228 restores its deformation, so that the limiting rod 225 is reset. When the rotating ring 216 rotates, it drives several protrusions 227 to rotate. The limit rod 225 can increase the resistance to the rotation of the rotating ring 216, thereby preventing the L-shaped rod 214 from rotating in a circle without moving when the rotating ring 211 drives the rotating ring 216 and the L-shaped rod 214 to move. By increasing the resistance, the rotating ring 211 can first drive the L-shaped rod 214 to move, and then drive the rotating ring 216 to rotate, thereby preventing the L-shaped silicone strip 215 from being unable to contact the detection head 106.

[0031] Working principle: When using the water quality monitoring equipment, first, according to Figure 1-Figure 11 As shown, in the aquaculture process, the water samples at different depths have different temperatures, dissolved oxygen, pH values, etc. When monitoring the water samples at different depths, the multi-stage electric push rod 103 is started to drive the movable plate 105 to move, and the movable plate 105 moves and slides on the guide rod 108 to limit the position, so that the position of the detection head 106 can be adjusted. When the movable plate 105 moves, the meshing of the rotating gear 203 and the rack 205 can drive the rotating shaft 202 to rotate. After the rotating shaft 202 rotates, the meshing of the first bevel gear 208 and the second bevel gear 209 can drive the rotating rod 207 to rotate on the positioning frame 206. After the rotating rod 207 rotates, the driven gear 203 is engaged with the gear 205. The rotating ring 211 can be driven to rotate by meshing with the teeth 212 on the rotating ring 211. After the rotating ring 211 rotates, the limiting ring 213 can be driven to slide on the limiting ring groove 2131 for limiting, and then the two L-shaped rods 214 can be driven to rotate in a circle. The L-shaped silicone strip 215 is relatively soft and can be used to clean the detection head 106. Impurities are not easy to adhere to the L-shaped silicone strip 215. When the rotating ring 211 rotates, it can push the sliding rod 2142 to move through the sliding groove 2111. Whether the rotating ring 211 rotates counterclockwise or clockwise, it can push the sliding rod 2142 to move close to the detection head 106. After the sliding rod 2142 moves, it can drive the L-shaped rod 214 to move. When the L-shaped rod 214 moves, it is guided by the push rod 222. The push rod 222 is tilted on the rotating ring 216, so that the sliding rod 2142 can push the L-shaped rod 214 to move obliquely upward while moving toward the detection head 106, so that the L-shaped silicone strip 215 is simultaneously in contact with the side wall and bottom surface of the detection head 106. When the rotating ring 211 and the rotating ring 216 are rotated, the detection head 106 can be fully cleaned, and the push rod 222 can compress the telescopic spring 223 during the movement, so that after the movable plate 105 stops moving, the push rod 222 can automatically reset, so that the L-shaped rod 214 can move obliquely downward, so that the L-shaped silicone strip 215 no longer contacts the side wall and bottom surface of the detection head 106, so that when not cleaning, the L-shaped silicone strip 215 will not block the detection head 106, thereby avoiding affecting normal monitoring and cleaning the detection head 106. When the rotating ring 211 is in operation, the L-shaped rod 214 can be driven to rotate in a circle, so that the rotating ring 216 rotates. When the rotating ring 216 rotates, the protrusion 227 can push the limiting rod 225 to move, so that the ball 226 rotates on the protrusion 227. When the limiting rod 225 slides on the support frame 224, the reset spring 228 can be stretched. When the ball 226 does not contact the protrusion 227, the reset spring 228 restores its deformation, so that the limiting rod 225 is reset, so that the rotating ring 216 rotates. The rotation of the rotating ring 216 can increase the resistance to the rotation of the rotating ring 216 through the limit rod 225, thereby preventing the L-shaped rod 214 from rotating in a circle without moving when the rotating ring 211 drives the rotating ring 216 and the L-shaped rod 214 to move. By increasing the resistance, the rotating ring 211 can first drive the L-shaped rod 214 to move, and then drive the rotating ring 216 to rotate, thereby preventing the L-shaped silicone strip 215 from being unable to contact the detection head 106.
