Technical Field

[0001] The present invention relates to the technical field of water quality detection and sampling, and particularly to a water quality detection and sampling device for environmental protection projects. Background Art

[0002] A water quality detection and sampling device is a device used for collecting water samples, conducting water quality monitoring and analysis. With the increasingly serious problem of water pollution, water quality monitoring has become an important means to ensure water resource safety and environmental protection. The role of the sampling device is to ensure that the collected water samples can truly reflect the water quality status of the water body for subsequent analysis and treatment.

[0003] The patent with the publication number CN221781923U discloses a water quality detection and sampling device for environmental protection projects, including an electric telescopic rod and a cylinder bottom; a clamping structure is arranged at the bottom end of the electric telescopic rod; a sampling cylinder is arranged at the bottom of the clamping structure. This patent is provided with a pulling structure. After reaching the designated position, the pull rod contracts, driving the pull plug to move together. The sealing ring moves on the inner wall of the sampling cylinder, separating the water-filled space and the waterless space inside the built-in cavity, with better sealing performance. The sealing ring is evenly inlaid on the outer wall of the pull plug, playing a role of multiple seals. And when the sealing ring is worn, only the sealing ring needs to be replaced, without the need to replace the pull plug together, realizing the pulling function of this setting and improving the environmental protection performance of this water quality detection and sampling device for environmental protection projects. However, when the above device is in use, it is difficult to comprehensively extract water quality samples at different water levels and depths in the reservoir, resulting in inaccurate extraction of sample water and affecting the accuracy of subsequent water quality detection. Therefore, a water quality detection and sampling device for environmental protection projects is proposed to solve the above-mentioned problems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1 - 8, an embodiment of the present invention is: a water quality detection sampling device for environmental protection engineering, including a floating disk 1, a circular shell 2 is fixedly connected to the top of the floating disk 1, a detection box 3 is fixedly connected to the top of the floating disk 1, a bottom circular block 4 is fixedly connected to the bottom of the floating disk 1, a motor 5 is fixedly connected to the inner wall of the circular shell 2, a water pump 6 is fixedly connected to the inner wall of the circular shell 2, the output end of the motor 5 is fixedly connected to a reciprocating lead screw 7, a fixed rod 9 is fixedly connected to the inner wall of the bottom circular block 4, a moving circular block 8 is movably connected to the circumferential surface of the reciprocating lead screw 7, a limiting column 10 is fixedly connected to the top of the fixed rod 9, a protection mechanism 12 for underwater protection is arranged on the inner wall of the bottom circular block 4, a filtering mechanism 13 for filtering water is arranged on the inner wall of the detection box 3, an electric telescopic rod 14 is fixedly connected to the inner wall of the floating disk 1, a connecting disk 15 is fixedly connected to the telescopic end of the electric telescopic rod 14, a cross column 16 is slidably connected to the inner wall of the connecting disk 15, one end of a water pipe 11 is fixedly communicated with the water pump 6, the other end of the water pipe 11 is fixedly communicated with the cross column 16, a spiral assembly 17 is installed on the inner wall of the connecting disk 15, an extraction block 18 is fixedly connected to the bottom of the cross column 16. When the device is used, the worker places the whole device on the water surface of the reservoir. At this time, the motor 5 will start, and the output end of the motor 5 will drive the reciprocating lead screw 7 to rotate. The reciprocating lead screw 7 will drive the moving circular block 8 to rotate. However, at this time, the moving circular block 8 is limited by the limiting column 10, and the moving circular block 8 can only move up and down reciprocally through the reciprocating groove on the surface of the reciprocating lead screw 7. The movement of the moving circular block 8 will contact the connecting disk 15, and the moving circular block 8 will push the connecting disk 15 to release the limit and move downward. When the connecting disk 15 moves, the motor built in the spiral assembly 17 will start and drive the spiral assembly 17 to start working. The spiral assembly 17 will push the connecting disk 15 to move underwater. The movement of the connecting disk 15 will drive the telescopic end of the electric telescopic rod 14 to move. While the connecting disk 15 is moving, it will also drive the cross column 16 to move. The movement of the cross column 16 will drive the extraction block 18 to move. At this time, the water pump 6 will pump the water at different depths in the reservoir into the detection box 3 through the water pipe 11 and the extraction block 18 for detection, which can improve the detection range of the device, improve the detection accuracy, detect different depths in the reservoir, and can improve the use effect of the device. An elastic telescopic rod 19 is fixedly connected to the inner wall of the bottom circular block 4. The extraction block 18 is fixedly communicated with the cross column 16. The moving circular block 8 is slidably connected to the inner wall of the limiting column 10, and the moving circular block 8 contacts the fixed rod 9. At the same time, after the device finishes detection and needs to continue to detect in other areas, the electric telescopic rod 14 will drive the connecting disk 15 to rise. After the connecting disk 15 rises a certain distance, the connecting disk 15 will contact and squeeze the inclined block of the elastic telescopic rod 19 by itself. The elastic telescopic rod 19 will be stuck with the connecting disk 15 to ensure that when the device moves to other areas, the sundries and weeds in the water cannot contact the rotating and moving parts of the device, avoiding jamming when the device moves.The detection accuracy of the device is reduced, affecting subsequent data statistics and improving the usage efficiency of the device.

[0015] The protection mechanism 12 includes a first connecting column 1201, a ring block 1202, and a circular ring scraping plate 1203. The first connecting column 1201 is fixedly connected to the bottom of the connecting disc 15. The ring block 1202 is fixedly connected to the bottom of the first connecting column 1201. The circular ring scraping plate 1203 is fixedly connected to the inner wall of the ring block 1202. When the device is started, the movement of the connecting disc 15 will drive the movement of the first connecting column 1201. The movement of the first connecting column 1201 will drive the movement of the ring block 1202. During the downward movement of the ring block 1202, it will drive the movement of the circular ring scraping plate 1203. The movement of the circular ring scraping plate 1203 will scrape the surface of the extraction block 18. In the deeper part of the reservoir, there are more sundries and waterweeds. If the sundries and waterweeds are not cleaned and scraped in time, they will block the water extraction part of the extraction block 18. The circular ring scraping plate 1203 can improve the detection efficiency of the device, prevent the device from being unable to extract water, resulting in the device being unable to detect the water quality, and further improve the detection speed of the device. The protection mechanism 12 further includes an isolation plate 1204, a connecting block 1205, a pushing plate 1206, a second connecting column 1207, a second elastic telescopic rod 1208, and a knocking round block 1209. The isolation plate 1204 is fixedly connected to the inner wall of the bottom circular block 4. The connecting block 1205 is fixedly connected to the inner wall of the moving circular block 8. The pushing plate 1206 is fixedly connected to the inner wall of the connecting block 1205. The second connecting column 1207 is fixedly connected to the bottom of the pushing plate 1206. The second elastic telescopic rod 1208 is fixedly connected to the inner wall of the second connecting column 1207. The knocking round block 1209 is fixedly connected to the telescopic end of the second elastic telescopic rod 1208. The circular ring scraping plate 1203 contacts the extraction block 18, the pushing plate 1206 contacts the bottom circular block 4, and the knocking round block 1209 contacts the isolation plate 1204. At the same time, when the moving circular block 8 moves up and down, the movement of the moving circular block 8 will drive the movement of the connecting block 1205. The movement of the connecting block 1205 will drive the movement of the pushing plate 1206. The pushing plate 1206 will drive the movement of the second connecting column 1207. The movement of the second connecting column 1207 will drive the movement of the second elastic telescopic rod 1208. The movement of the second elastic telescopic rod 1208 will drive the movement of the knocking round block 1209. During the movement of the knocking round block 1209, the knocking round block 1209 will contact and knock the isolation plate 1204, which can make the sundries attached to the surface of the isolation plate 1204 fall off. At the same time, the knocking of the knocking round block 1209 will drive the fish in the reservoir to stay away from the device, preventing other factors in the reservoir from affecting the detection of the device.

[0016] Working principle: When the device is in use, the worker places the whole device on the water surface of the reservoir. At this time, the motor 5 will start, and the output end of the motor 5 will drive the reciprocating lead screw 7 to rotate. The reciprocating lead screw 7 will drive the moving circular block 8 to rotate. However, at this time, the moving circular block 8 is limited by the limiting column 10, and the moving circular block 8 can only move up and down reciprocally through the reciprocating groove on the surface of the reciprocating lead screw 7. The movement of the moving circular block 8 will contact the connecting plate 15, and the moving circular block 8 will push the connecting plate 15 to release the limit and move downward. When the connecting plate 15 moves, the motor built in the spiral assembly 17 will start and drive the spiral assembly 17 to start working. The spiral assembly 17 will push the connecting plate 15 to move underwater. The movement of the connecting plate 15 will drive the telescopic end of the electric telescopic rod 14 to move. While the connecting plate 15 is moving, it will also drive the cross column 16 to move. The movement of the cross column 16 will drive the extraction block 18 to move. At this time, the water pump 6 will extract the water at different depths in the reservoir into the inside of the detection box 3 through the water pipe 11 and the extraction block 18 for detection, which can improve the detection range of the device, improve the detection accuracy, detect different depths in the reservoir, and improve the use effect of the device. At the same time, after the device finishes detection and needs to continue to detect other areas, the electric telescopic rod 14 will drive the connecting plate 15 to rise. After the connecting plate 15 rises a certain distance, the connecting plate 15 will contact and squeeze the inclined block of the elastic telescopic rod 19 itself. The elastic telescopic rod 19 will be stuck with the connecting plate 15, ensuring that when the device moves to other areas, the sundries and weeds in the water cannot contact the rotating and moving parts of the device, avoiding jamming when the device moves, resulting in a decrease in the detection accuracy of the device and affecting subsequent data statistics, and improving the use efficiency of the device.

[0017] When the device is started, the movement of the connecting disk 15 drives the movement of the first connecting column 1201. The movement of the first connecting column 1201 drives the movement of the ring block 1202. During the downward movement of the ring block 1202, it drives the movement of the circular ring scraping plate 1203. The movement of the circular ring scraping plate 1203 scrapes the surface of the extraction block 18. In the deeper part of the reservoir, there are more sundries and waterweeds. If the sundries and waterweeds are not cleaned and scraped in time, they will block the water extraction part of the extraction block 18. The circular ring scraping plate 1203 can improve the detection efficiency of the device, prevent the device from being unable to extract water, resulting in the device being unable to detect the water quality, and further improve the detection speed of the device. At the same time, when the moving circular block 8 moves up and down, the movement of the moving circular block 8 drives the movement of the connecting block 1205. The movement of the connecting block 1205 drives the movement of the pushing plate 1206. The pushing plate 1206 drives the movement of the second connecting column 1207. The movement of the second connecting column 1207 drives the movement of the second elastic telescopic rod 1208. The movement of the second elastic telescopic rod 1208 drives the movement of the knocking circular block 1209. During the movement of the knocking circular block 1209, the knocking circular block 1209 contacts and knocks the isolation plate 1204, which can shake off the sundries attached to the surface of the isolation plate 1204. At the same time, the knocking of the knocking circular block 1209 drives the fish in the reservoir to drive them away from the device, avoiding other factors in the reservoir from affecting the detection of the device.

[0018] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the filtering mechanism 13 includes a second water pipe 1301, a fixed cylinder 1302, a rotating column 1303, and a guiding inclined plate 1304. The fixed cylinder 1302 is fixedly connected to the inner wall of the detection box 3, the rotating column 1303 is rotatably connected to the inner wall of the fixed cylinder 1302, and the guiding inclined plate 1304 is fixedly connected to the circumferential surface of the rotating column 1303. When the device is in use, the water pump 6 pumps water into the interior of the detection box 3 through the first water pipe 11, and the water in the reservoir enters the interior of the fixed cylinder 1302 through the second water pipe 1301. At this time, the water contacts the guiding inclined plate 1304 and pushes the rotating column 1303 through the guiding inclined plate 1304, causing the rotating column 1303 to rotate. At this time, the fixed cylinder 1302 will layer and filter the sample water, improving the filtering speed of the sample water and the detection speed of the device, and avoiding the reduction of the detection efficiency of the device due to the slow filtering speed of the sample water. The filtering mechanism 13 further includes a first inclined block 1305, a second inclined block 1306, a push plate 1307, a detector 1308, a long column 1309, a hinged column 1310, and a rotating plate 1311.

One end of the second water pipe 1301 is fixedly communicated with the water pump 6, the other end of the second water pipe 1301 is fixedly communicated with the fixed cylinder 1302, the second water pipe 1301 contacts the detection box 3, the push plate 1307 contacts the detection box 3, and the long column 1309 contacts the rotating plate 1311. At the same time, after the detection of the sample water inside the detection box 3 is completed, the reciprocating movement of the pushing plate 1206 up and down will drive the first inclined block 1305 to move. After the first inclined block 1305 moves a certain distance, it will contact the second inclined block 1306 and squeeze the inclined surface of the second inclined block 1306 through its own inclined block. At this time, the second inclined block 1306 will move under the extrusion, the movement of the second inclined block 1306 will drive the push plate 1307 to move, the movement of the push plate 1307 will drive the long column 1309 to move, and the long column 1309 will squeeze and push the rotating plate 1311 to rotate. At this time, the opening of the detection box 3 will be opened, and the movement of the rotating plate 1311 can discharge the sample water inside the detection box 3 through the opening of the detection box 3, improving the flexibility of the device during long-term use, avoiding the decrease in detection accuracy caused by the residual sample water from the previous time inside the detection box 3 in subsequent water quality detection, and improving the detection accuracy of the device for multiple detections.

[0019] Working principle: When the device is in use, the water pump 6 pumps water into the interior of the detection box 3 through the first water pipe 11. The water in the reservoir will enter the interior of the fixed cylinder 1302 through the second water pipe 1301. At this time, the water will contact the diversion inclined plate 1304 and push the rotating column 1303 through the diversion inclined plate 1304, causing the rotating column 1303 to rotate. At this time, the fixed cylinder 1302 will layer and filter the sample water, improving the filtering speed of the sample water, increasing the detection speed of the device, and preventing the detection efficiency of the device from decreasing due to the slow filtering speed of the sample water. At the same time, after the detection of the sample water inside the detection box 3 is completed, the reciprocating movement of the push plate 1206 will drive the first inclined block 1305 to move. After the first inclined block 1305 moves a certain distance, it will contact the second inclined block 1306 and squeeze the inclined surface of the second inclined block 1306 through its own inclined block. At this time, the second inclined block 1306 will move under the extrusion. The movement of the second inclined block 1306 will drive the push plate 1307 to move. The movement of the push plate 1307 will drive the long column 1309 to move. The long column 1309 will squeeze and push the rotating plate 1311 to rotate. At this time, the opening of the detection box 3 will be opened. The movement of the rotating plate 1311 can discharge the sample water inside the detection box 3 through the opening of the detection box 3, improving the flexibility of the device during long-term use, preventing the detection accuracy from decreasing due to the residual sample water from the previous time inside the detection box 3 in subsequent water quality detections, and improving the detection accuracy of the device during multiple detections.
