However, in actual use, it can only adjust the orientation of the detector, but it is difficult to quickly collect samples for water quality detection at different water levels.

[0003] Within the scope of the prior art, water quality detection instruments and sampling devices are usually integrated into unmanned boats or buoy systems to achieve real-time monitoring of water quality or adjust the detection position according to requirements, and the detection equipment is transported to the designated water area for detection through the mobility of the unmanned boat. However, a key problem faced in the implementation of such detection operations is that the detection equipment needs to have an automatic isolation mechanism inside to ensure detection accuracy, but the existing detection equipment with this function often has unsatisfactory sealing performance, which leads to the easy mixing of water quality samples collected at different water depths, and then causes deviations in detection data. In addition, the current level of intelligence in the water sample collection process needs to be improved, and the steps of sample assembly and sampling are relatively complex and cumbersome, affecting the overall operation efficiency and user experience. In view of this, we propose an automated sewage water quality detector and a usage method thereof. Summary of the Invention

[0027] A method for detecting sewage water quality includes the following detection steps:

[0028] S1. When in use, place the hull mechanism on the water surface, adjust its position through the driver, and adjust the water level height where it is located through the pressure assembly, the first control valve and the second control valve;

[0029] S2. When collecting, start the adjusting assembly, extract the liquid below through the movement of the position of the movable assembly, and complete the liquid collection;

[0030] S3. When detecting, take out the box body assembly, and take out the collecting assembly from below, then the sewage water quality can be detected by the detector.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. The present invention designs an adjustment component, a sealing component and a collection component. When collecting sewage samples, the height of the movable component is adjusted by the adjustment component. This adjustment causes the internal pressure of the movable component and the collection component to increase, and then the external gas and liquid are squeezed, pushing the sealing component upward. As the sealing component moves upward, a large amount of liquid can quickly enter the collection component. At the same time, during the process of the adjustment component pulling the movable component, the positioning component gradually contacts the guiding component, resulting in the gradual contraction of the positioning component, thus releasing the fixation of the sleeved component. At this time, the adjustment component is separated from the movable component. As a large amount of liquid enters the collection component, the internal and external pressures gradually equalize, and the sealing component resets, retaining the liquid in the collection component. After the sewage sample collection is completed, the box component can be conveniently removed, and the collection component that has collected sewage samples at different water levels can be taken out. This enables the device to quickly move to different water levels in the sewage and select different collection components to recycle the sewage according to different water levels. This design avoids the situation of sample mixing when recycling sewage at different water levels, ensuring the accuracy of the data during sewage detection. In addition, after the sewage detection is completed, the adjustment component will automatically separate from the sealing component, which greatly reduces the difficulty of taking out the sewage sample, improving the automation degree of the device and the efficiency during operation.

[0033] 2. The present invention also designs an adjustment component, a collection component and a movable component. When the electric push rod contracts, it drives the bearing plate to move upward through the connecting column. At this time, the bearing plate pulls the tooth card, causing the piston plate to move upward synchronously. As the piston plate moves upward, the air pressure in the collection box changes, and the external liquid squeezes the sealing plate through the collection hole, causing the sealing plate to move upward, so that a large amount of sewage samples enter the collection box. As the electric push rod continues to move, the push plate will contact the guiding block. Since the lower part of the guiding block is designed as an inclined surface, the push plate will push the sliding rod to move along this inclined surface. During the movement of the sliding rod, it will drive the tooth card to gradually move away from the bearing plate. At this time, the piston plate stops moving. When the liquid continuously enters the collection box and the internal and external air pressures of the collection box tend to be the same, the first spring will squeeze the sealing plate to reset, thus locking the sewage sample in the collection box. During detection, since the bearing plate and the tooth card have been separated, the collection box can be simply taken out from the box component. Such a design reduces the usage difficulty of the device and improves the efficiency of collecting sewage through automatic adjustment. At the same time, with the use of the sealing plate, on the one hand, it reduces the possibility of sewage leakage, and on the other hand, it ensures that the device can stably extract sewage at the specified position.

[0034] 3. The present invention also designs a movable component and a positioning component. After taking out the sewage sample by squeezing the sealing plate and cleaning the inside of the collection box, when the collection box needs to be reinstalled into the box housing, since the liquid inside the collection box has been drained, it can be fixed by the friction plate during installation. Subsequently, the electric push rod pushes the bearing plate downward. This action will synchronously push the piston plate downward, causing the push plate to gradually move away from the guide block. At this time, the second spring comes into play and pushes the tooth block to move above the bearing plate, making the bearing plate located between the piston plate and the tooth block, thus completing the fixation of the bearing plate. Such a design enables the device to quickly install the collection box after taking out the sewage sample, and after the installation is completed, through the extension of the electric push rod, the internal structure of the device can be automatically connected. Such an automatic connection ensures that when extracting sewage subsequently, the bearing plate can drive the piston plate to move stably. This process not only reduces the usage difficulty of the device but also guarantees the sewage extraction effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] As Figures 1 to 9 shown, an automatic sewage water quality detector and usage method involved in the present invention include a detector 28, a detection ship 11 and a driver 16, and further include,

[0057] Hull mechanism 1, including detection ship 11, first control valve 12 arranged above detection ship 11, second control valve 15 located below detection ship 11, bracket 14, pressure assembly 13 connected to detection ship 11, driver 16, mounting groove 17 and positioning groove 18 located above detection ship 11. Among them, bracket 14 is located below detection ship 11, and driver 16 is connected to detection ship 11; and, detection mechanism 2, including box body assembly 21, collection assembly 22 arranged inside box body assembly 21, sealing assembly 23 located inside collection assembly 22, movable assembly 24 connected to sealing assembly 23, positioning assembly 25, guiding assembly 26 connected to collection assembly 22, adjusting assembly 27 and detector 28. Among them, positioning assembly 25 is connected to movable assembly 24, adjusting assembly 27 is connected to box body assembly 21, and detector 28 is located inside box body assembly 21. By designing adjusting assembly 27, sealing assembly 23 and collection assembly 22, when collecting sewage samples, the height of movable assembly 24 is adjusted through adjusting assembly 27. This adjustment causes the internal pressure of movable assembly 24 and collection assembly 22 to increase, and then the external gas and liquid are squeezed, pushing sealing assembly 23 upward. As sealing assembly 23 moves upward, a large amount of liquid can quickly enter collection assembly 22. At the same time, during the process of adjusting assembly 27 pulling movable assembly 24, positioning assembly 25 gradually contacts guiding assembly 26, resulting in the gradual contraction of positioning assembly 25, thus releasing the fixation of the socket assembly. At this time, adjusting assembly 27 is separated from movable assembly 24. As a large amount of liquid enters collection assembly 22, the internal and external pressures gradually equalize, and sealing assembly 23 resets, retaining the liquid in collection assembly 22. After the sewage sample collection is completed, box body assembly 21 can be conveniently removed, and collection assembly 22 that has collected sewage samples at different water levels can be taken out. This enables the device to quickly move to different water levels in the sewage and select different collection assemblies 22 for sewage recovery according to different water levels. This design avoids the situation of sample mixing when recovering sewage at different water levels, ensuring the accuracy of data during sewage detection. In addition, after the sewage detection is completed, adjusting assembly 27 will automatically separate from sealing assembly 23, which greatly reduces the difficulty of taking out sewage samples, improves the automation degree of the device and the efficiency during operation.

[0058] In an embodiment of the present invention, the detection ship 11 is in communication with the pressure assembly 13. The number of the first control valves 12 and the second control valves 15 is several. A plurality of the first control valves 12 are arranged above the detection ship 11, and a plurality of the second control valves 15 are arranged below the detection ship 11. The lower part of the detection ship 11 is fixedly connected to the top end of the support 14. The driver 16 is fixedly connected to the detection ship 11. The installation groove 17 is opened above the detection ship 11. The number of the positioning grooves 18 is several, and a plurality of the positioning grooves 18 are opened in the installation groove 17. The inner wall of the box body assembly 21 is clamped with a plurality of collection assemblies 22, and the inner walls of a plurality of the collection assemblies 22 are respectively slidably connected to a plurality of movable assemblies 24. The lower parts of the inner walls of a plurality of the collection assemblies 22 are respectively fixedly connected to a plurality of sealing assemblies 23. The inner wall of the collection assembly 22 is fixedly connected to the guiding assembly 26. The upper part of the movable assembly 24 is fixedly connected to the positioning assembly 25. The number of the adjusting assemblies 27 is several, and a plurality of the adjusting assemblies 27 are fixedly connected to the upper part of the inner wall of the box body assembly 21. The detector 28 is arranged above the inner wall of the box body assembly 21. The box body assembly 21 is clamped in the installation groove 17 and the positioning groove 18. By designing the adjusting assembly 27, the collection assembly 22 and the movable assembly 24, when the electric push rod 271 contracts, it drives the bearing plate 275 to move upward through the connecting column 274. At this time, the bearing plate 275 pulls the clamping teeth 256 to synchronously move the piston plate 241 upward. As the piston plate 241 moves upward, the air pressure in the collection box 221 changes. The external liquid squeezes the sealing plate 235 through the collection hole 222, causing the sealing plate 235 to move upward, so that a large amount of sewage samples enter the collection box 221. As the electric push rod 271 continues to move, the push plate 255 contacts the guiding block 261. Since the lower part of the guiding block 261 is designed as an inclined surface, the push plate 255 pushes the sliding rod 253 to move along this inclined surface. During the movement of the sliding rod 253, it drives the clamping teeth 256 to gradually move away from the bearing plate 275. At this time, the piston plate 241 stops moving. When the liquid continuously enters the collection box 221 and the air pressure inside and outside the collection box 221 tends to be the same, the first spring 234 squeezes the sealing plate 235 to reset, thereby locking the sewage sample in the collection box 221. During the detection, since the bearing plate 275 is separated from the clamping teeth 256, only the collection box 221 needs to be simply taken out of the box body assembly 21. Such a design reduces the use difficulty of the device and improves the efficiency of collecting sewage through automatic adjustment. At the same time, with the use of the sealing plate 235, on the one hand, the possibility of sewage leakage is reduced, and on the other hand, it ensures that the device can stably extract the sewage at the specified position.

[0059] In an embodiment of the present invention, the pressure assembly 13 includes a connecting pipe 131. The lower part of the connecting pipe 131 communicates with two conduits 132. The bottom ends of the two conduits 132 are respectively communicated with two injection pressure tanks 133. There are several injection pressure tanks 133, and the several injection pressure tanks 133 are communicated with each other. A base 134 is fixedly connected to the lower part of the several injection pressure tanks 133. The lower part of the base 134 and the lower part of the bracket 14 are at the same horizontal height. The several injection pressure tanks 133 are connected through the same controller. The connecting pipe 131 communicates with the detection ship 11. The detection ship 11 is sealed. The box body assembly 21 includes a top plate 211. A box body outer shell 212 is fixedly connected to the lower part of the top plate 211. Reinforcing plates 213 are fixedly connected to both sides of the inner wall of the box body outer shell 212. Several friction plates 214 are fixedly connected inside the box body outer shell 212. Friction grooves 215 are formed on both sides of the several friction plates 214. Clasps 216 are fixedly connected to the periphery of the top plate 211. A handle 217 is fixedly connected to the upper part of the top plate 211. The top plate 211 is clamped in the positioning groove 18 through the clasp 216. Both sides of the collection assembly 22 are respectively lapped with the two friction plates 214. The adjusting assembly 27 and the detector 28 are both fixedly connected to the upper part of the inner wall of the box body outer shell 212. By arranging a one-way valve above the piston plate 241, when the piston plate 241 is pushed down, the gas below the piston plate 241 can be discharged along the one-way valve, ensuring the stability of the piston plate 241 during movement.

[0060] As another embodiment of the present invention, the collecting assembly 22 includes a collecting box 221, a collecting hole 222 is opened at the bottom of the inner wall of the collecting box 221, a plurality of blocking pieces 224 are fixedly connected to the inner wall of the collecting hole 222, a sealing tube 223 is fixedly connected to the bottom of the inner wall of the collecting box 221, the sealing tube 223 is communicated with the collecting hole 222, the movable assembly 24 is slidably connected in the collecting box 221, the sealing assembly 23 is fixedly connected to the collecting box 221, the guide assembly 26 is fixedly connected to the inner wall of the collecting box 221, the sealing assembly 23 includes a positioning frame 231, the top of the positioning frame 231 is fixedly connected to the mounting plate 232, the bottom of the mounting plate 232 is fixedly connected to the telescopic rod 233, the telescopic rod 233 is fixedly connected to the first spring 234, the bottom ends of the first spring 234 and the telescopic rod 233 are fixedly connected to the sealing plate 235, The positioning frame 231 is fixedly connected to the lower part of the inner wall of the collection box 221, and the sealing plate 235 is slidably connected to the sealing tube 223. The size of the sealing plate 235 is adapted to the size of the inner wall of the sealing tube 223. The movable component 24 includes a piston plate 241. The upper part of the piston plate 241 is fixedly connected to the limiting cylinder 242. The limiting cylinder 242 is provided with a plurality of slots 243. A one-way valve is provided above the piston plate 241. The size of the piston plate 241 is adapted to the size of the inner wall of the collection box 221. The piston plate 241 is slidably connected to the collection box 221. The upper part of the piston plate 241 is fixedly connected to the positioning component 25. By designing a baffle 224 in the collection hole 222, it is avoided that the sealing plate 235 slides out of the collection hole 222 along the sealing tube 223 when the piston plate 241 is pressed down, and it is difficult to reset it, thereby ensuring the service life of the device.

[0061] Because the guide block 261 is tilted at its bottom, the baffle moves when it contacts it, thereby driving the slide rod 253 and the gear block to move. After the piston plate 241 moves to a certain distance, the gear block will loosen its fixation on the load.

[0062] As another embodiment of the present invention, the positioning component 25 includes a positioning ring 251. A plurality of sliding sleeves 252 are fixedly connected to the inner wall of the positioning ring 251. A sliding rod 253 is slidably connected within the sliding sleeve 252. A second spring 254 is arranged within the sliding sleeve 252. Two ends of the second spring 254 are respectively fixedly connected to one side of the inner wall of the sliding sleeve 252 and one end of the sliding rod 253. The other end of the sliding rod 253 passes through a push plate 255 and is fixedly connected to a tooth 256. An inclined groove 257 is arranged above the tooth 256. The tooth 256 is located within a slot 243. The tooth 256 abuts against an adjustment component 27. The bottom end of the adjustment component 27 is located within a limiting cylinder 242. The positioning ring 251 is fixedly connected above a piston plate 241. The guiding component 26 includes a plurality of guiding blocks 261. Two guiding blocks 261 are arranged in the same direction. The plurality of guiding blocks 261 are fixedly connected to the same mounting ring 262. The mounting ring 262 is fixedly connected to the inner wall of the collection box 221. The adjustment component 27 includes an electric push rod 271. The bottom end of the electric push rod 271 is threadedly connected to a lead screw 273 through a nut 272. The bottom end of the lead screw 273 is fixedly connected to a connecting column 274. The bottom end of the connecting column 274 is fixedly connected to a bearing plate 275. Both the bearing plate 275 and the connecting column 274 are located within the limiting cylinder 242. The lower part of the push plate 255 abuts against the upper part of the bearing plate 275. The electric push rod 271 is fixedly connected above the inner wall of the box housing 212. By designing the movable component 24 and the positioning component 25, after taking out the sewage sample by squeezing the sealing plate 235 and cleaning the inside of the collection box 221, it is necessary to reinstall the collection box 221 into the box housing 212. Since the liquid inside the collection box 221 has been discharged, it can be fixed by the friction plate 214 during installation. Subsequently, the electric push rod 271 pushes the bearing plate 275 downward. This action will synchronously push the piston plate 241 downward, causing the push plate 255 to gradually move away from the guiding block 261. At this time, the second spring 254 comes into play, pushing the tooth block to move above the bearing plate 275, so that the bearing plate 275 is located between the piston plate 241 and the tooth block, thereby completing the fixation of the bearing plate 275. Such a design enables the device to quickly install the collection box 221 after taking out the sewage sample, and after the installation is completed, through the extension of the electric push rod 271, the internal structure of the device can be automatically connected. Such an automatic connection ensures that during subsequent sewage extraction, the bearing plate 275 can drive the piston plate 241 to move stably. This process not only reduces the usage difficulty of the device but also ensures the sewage extraction effect of the device.

[0063] Working principle: This embodiment provides an automated sewage water quality detector and its usage method. When in use, the position of the detection ship 11 is controlled by the driver 16. First, the first control valve 12 and the second control valve 15 are started, so that a large amount of liquid flows into the detection ship 11 along the second control valve 15, and at the same time, air is discharged along the first control valve 12. When it is necessary to hover at a specified water level, the first control valve 12 and the second control valve 15 are closed, and gas is injected into the detection ship 11 through the injection pressure tank 133 to adjust the internal liquid storage volume;

[0064] When collecting sewage samples, the height of the movable component 24 is adjusted through the adjustment component 27, thereby creating a pressure difference inside the collecting component 22 between the movable component 24. This pressure difference causes the external gas and liquid to squeeze the sealing component 23, causing it to move upward, thereby allowing a large amount of liquid to quickly pour into the collecting component 22. While the adjustment component 27 pulls the movable component 24, the positioning component 25 gradually comes into contact with the guiding component 26 and thus gradually contracts, thereby releasing the fixation of the socket component. At this time, the adjustment component 27 is separated from the movable component 24. As a large amount of liquid enters the collecting component 22, the internal and external pressures gradually balance, and the sealing component 23 resets, firmly retaining the liquid in the collecting component 22. After the sewage sample collection is completed, the box body component 21 can be conveniently removed, and the collecting component 22 that has collected sewage samples at different water levels can be taken out;

[0065] When the electric push rod 271 contracts, it drives the bearing plate 275 to move upward through the connecting column 274. At this time, the bearing plate 275 pulls the piston plate 241 to move upward synchronously by pulling the engaging teeth 256. As the piston plate 241 rises, the air pressure in the collection box 221 below it changes, and the external liquid squeezes the sealing plate 235 through the collection hole 222, causing the sealing plate 235 to move upward, thereby allowing a large amount of sewage samples to enter the collection box 221. As the electric push rod 271 continues to contract, the push plate 255 will come into contact with the guiding block 261. Since the lower part of the guiding block 261 is designed as an inclined surface, the push plate 255 will push the sliding rod 253 to move along this inclined surface. During the movement of the sliding rod 253, it will drive the engaging teeth 256 to gradually move away from the bearing plate 275. At this time, the piston plate 241 stops moving. When the liquid continues to enter the collection box 221 and the internal and external air pressures of the collection box 221 tend to balance, the first spring 234 will squeeze the sealing plate 235 to reset, thereby locking the sewage sample in the collection box 221. During detection, since the bearing plate 275 and the engaging teeth 256 have been separated, it is only necessary to simply take out the collection box 221 from the box body component 21;

[0066] After taking out the sewage sample through the extrusion sealing plate 235 and cleaning the inside of the collection box 221, the collection box 221 needs to be reinstalled into the box housing 212. Since the liquid inside the collection box 221 has been drained, it can be firmly installed through the friction plate 214. After the installation is completed, the electric push rod 271 starts to push the bearing plate 275 downward. This action will synchronously push the piston plate 241 downward, causing the push plate 255 to gradually separate from the guide block 261. At this time, the second spring 254 comes into play, pushing the tooth block to move above the bearing plate 275, so that the bearing plate 275 is clamped between the piston plate 241 and the tooth block, thus completing the fixation of the bearing plate 275.
