Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a patrol inspection device for water conservancy projects. Background Art

[0002] With the development of science and technology and people's attention to water resources, smart water conservancy projects are important livelihood projects and an important part of smart cities. Among them, water environment protection is an important livelihood project in smart water conservancy projects. However, floating objects often appear in the water bodies of existing reservoirs or rivers. These floating objects are either garbage discarded by humans, or branches and leaves of trees, aquatic plants floating with the water flow and other organic matter. As these floating objects soak in the water body for a period of time, they will rot, pollute the water body, and seriously affect the water quality. Therefore, relevant water conservancy construction staff will regularly inspect the river channels of various tributaries or main streams in order to promptly discover river water pollution problems and prevent the water body in the water area from being further polluted and damaged. With the continuous improvement and development of drone technology, drones have begun to be used in river inspections of water conservancy projects. Staff can remotely control drones to fly in the high altitude area above the river for panoramic inspections and observations of the river. In order to avoid the accumulation and fermentation of floating objects and cause more serious pollution to the water body, these floating objects need to be removed in time. In order to avoid the accumulation and fermentation of floating objects and cause more serious pollution to the water body, these floating objects need to be removed in time.

[0003] The existing method is to set up interception nets or dam bodies and other floating object capture mechanisms at the entrances and exits of rivers or reservoirs. Floating objects can only be intercepted when the height difference causes water flow, and cannot be intercepted on a flat lake surface, causing floating objects to float in the water for a long time.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-10 The present invention provides an embodiment: a water conservancy project inspection device, comprising a drone body 1, four sets of blades 2 are arranged on the drone body 1, a camera 3 is arranged on the left side of the drone body 1, and two sets of legs 4 are installed on the lower side of the drone body 1.

[0033] A fixing plate 5 is fixedly installed on the lower side of the drone body 1, and a collecting box 6 is movably installed on the lower side of the fixing plate 5. Two groups of card slots 7 are opened in the lower side of the fixing plate 5, and two groups of card blocks 8 are arranged on the upper side of the collecting box 6. The two groups of card blocks 8 are movably inserted in the two groups of card slots 7. Baffles 9 are rotatably installed at the openings of the two groups of card slots 7. Bolts 10 are inserted through threads in the two groups of baffles 9 and the two groups of card blocks 8. A collecting component is arranged in the left end of the collecting box 6, and a sampling component is arranged in the right end of the collecting box 6. The device inserts the collecting box 6 into the two groups of card slots 7 through the two groups of card blocks 8 at the upper end, and after the two groups of baffles 9 are flipped and fixed to the fixing plate 5 with bolts 10, the collecting box 6 can be connected to the drone body 1, and then the drone body 1 is flown through the four groups of blades 2. The drone body 1 flies During the process, the camera 3 is used to identify floating objects on the water surface, the drone body 1 descends and the bottom of the collecting box 6 is sunk under the water surface, and the floating objects on the water surface are photographed and identified by the camera 3. When it is determined to be a pollutant, the collecting component collects the items on the water surface that have been determined to be polluted floating objects, and puts the polluted floating objects into the collecting box 6, so as to facilitate the collection and cleaning of floating objects drifting on the river surface, improve the cleaning and maintenance effect of the river water quality, and do not need to manually clean the river surface by boat, so as to improve the intelligence and convenience of river surface detection and maintenance, and when the collecting box 6 is about to enter the water surface, the sampling component pops up and is inserted into the river water, so that the river water can be extracted through the sampling component, which is convenient for the laboratory to accurately detect the extracted river water and improve the accuracy of river water detection.

[0034] Furthermore, the inner walls of the two groups of card slots 7 and the two groups of card blocks 8 are both T-shaped, and the two groups of card blocks 8 are adapted to the inner walls of the two groups of card slots 7. According to the shapes of the inner walls of the two groups of card slots 7 and the two groups of card blocks 8, after the two groups of card blocks 8 are inserted into the two groups of card slots 7, the two groups of card blocks 8 are prevented from sliding out of the two groups of card slots 7 by being pulled downward, so that the two groups of card blocks 8 can slide left and right in the two groups of card slots 7, and the openings of the two groups of card slots 7 are closed, so that the two groups of card blocks 8 can be fixed in the two groups of card slots 7, thereby improving the tightness of the two groups of card blocks 8 inserted in the two groups of card slots 7, and improving the anti-pulling and detachment effect when the two groups of card blocks 8 are inserted into the two groups of card slots 7.

[0035] Furthermore, the lower right side of the collecting box 6 is hollowed out, and the hole on the lower right side of the collecting box 6 is less than one millimeter. According to the hollowed-out structure on the lower right side of the collecting box 6, when the lower end of the collecting box 6 sinks below the water surface, river water can be put into the collecting box 6. Conversely, when the collecting box 6 rises from below the water surface, the river water in the collecting box 6 flows in from the hollowed-out portion on the lower side of the collecting box 6, and the water contained in the floating objects collected in the collecting box 6 seeps out through the hollowed-out portion on the lower side of the collecting box 6, thereby avoiding the excessive flight load of the drone body 1 caused by the accumulation of river water in the collecting box 6. According to the size of the hollowed-out hole on the lower right side of the collecting box 6, the floating objects collected in the collecting box 6 will not leak out through the hollowed-out portion on the lower right side of the collecting box 6, thereby improving the effect of separating the floating objects from water after collection.

[0036] Furthermore, the collecting device includes a paddle wheel 11, which is rotatably installed in the left end of the collecting box 6, and two groups of first rotating shafts 12 are rotatably installed in the collecting box 6, and the two groups of first rotating shafts 12 are sleeved with conveyor belts 13. A first synchronous wheel 19 is fixedly installed at the rear end of the paddle wheel 11, and a second synchronous wheel 20 is fixedly installed at the rear end of the first rotating shaft 12. A synchronous belt 22 is sleeved on the first synchronous wheel 19 and the second synchronous wheel 20, and a first motor 23 is fixedly installed in the rear end of the collecting box 6. The output shaft of the first motor 23 is fixedly connected to the second synchronous wheel 20. When the drone body 1 descends and sinks the lower side of the collecting box 6 under the water, the output shaft of the first motor 23 drives the two groups of second synchronous wheels 20, the paddle wheel 11, and the two groups of first rotating shafts 12. The paddle wheel 11 rotates and the conveyor belt 13 rotates, and the paddle wheel 11 rotates to scrape up the floating objects floating on the water surface, and as the paddle wheel 11 rotates, the side of the paddle wheel 11 that scrapes up the floating objects is turned downward through rotation, so that the floating objects scraped up by the paddle wheel 11 fall off and fall on the conveyor belt 13, and after the floating objects are brought into the collecting box 6, the floating objects that fall on the surface are sent to the right end of the collecting box 6 through the rotation of the two sets of first rotating shafts 12 and the conveyor belt 13, completing the collection and cleaning of the floating objects floating on the water surface, avoiding the decay of the floating objects caused by long-term flow on the water surface, and no manual collection of the floating objects by moving the boat on the water surface is required, which improves the convenience of collecting the floating objects floating on the water surface and reduces the labor intensity of workers caused by collecting floating objects on the river surface.

[0037] Furthermore, the paddle wheel 11 is made of a hollow wire mesh, and the paddle wheel 11 is located on the left side of the conveyor belt 13. The lower side of the paddle wheel 11 is higher than the upper side of the conveyor belt 13. This structure is based on the material of the paddle wheel 11, so that when the paddle wheel 11 rotates under the water surface, the water flow will not cause too much resistance to the paddle wheel 11, and will not significantly shift the flow of the river. It can also scrape up floating objects on the water surface without lifting the water, thereby reducing the thrust generated by the paddle wheel 11 rotating under the water surface, and preventing the paddle wheel 11 from rotating and driving the collection box 6 to move under the water surface, so that the collection box 6 can move with the flight of the drone body 1 without being moved by the paddle wheel 11 rotating under the water surface.

[0038] Furthermore, a second rotating shaft 14 is rotatably installed in the right end of the collecting box 6, a first bevel gear 15 is fixedly installed at the front end of the second rotating shaft 14, a third rotating shaft 16 is vertically installed in the right end of the collecting box 6, a second bevel gear 17 is fixedly installed on the upper end of the third rotating shaft 16, the second bevel gear 17 is meshed with the first bevel gear 15, a lever 18 is fixedly installed on the third rotating shaft 16, a third synchronous wheel 21 is fixedly installed at the rear end of the second rotating shaft 14, the right end of the synchronous belt 22 is sleeved on the third synchronous wheel 21, and the first motor 23 of the structure drives the conveyor belt 13 and the paddle wheel 11 to rotate, while the third synchronous wheel 21 is driven to rotate through the synchronous belt 22, and the third synchronous wheel 21 The rotation drives the second rotating shaft 14, the first bevel gear 15, the third rotating shaft 16, the second bevel gear 17 and the lever 18 to rotate. The lever 18 rotates to shift the floating objects transported into the right end of the collecting box 6 by the conveyor belt 13, so as to avoid the floating objects from piling up in one position when entering the collecting box 6. The floating objects entering the collecting box 6 can be evenly collected, and the weight of the floating objects at different positions in the collecting box 6 can be evenly collected. This avoids uneven weight at different positions caused by the accumulation of floating objects collected in the collecting box 6 when the drone body 1 and the four sets of blades 2 are flying, which makes the drone body 1 and the four sets of blades 2 unstable due to the higher weight on one side of the flying side, resulting in a short flight distance.

[0039] Furthermore, the sampling component includes a sampling chamber 24, which is provided in the right end of the collecting box 6, and two groups of straws 25 are fixedly installed in the sampling chamber 24, and water pumps 26 are fixedly installed on the two groups of straws 25, and sampling heads 27 are fixedly installed at the lower ends of the two groups of water pumps 26, and fixing rings 28 are fixedly installed at the lower ends of the two groups of water pumps 26, and springs 29 are sleeved between the two groups of fixing rings 28 and the two groups of sampling heads 27, and a bidirectional motor 30 is fixedly installed in the sampling chamber 24, and winding drums 31 are installed in the front and rear ends of the sampling chamber 24, and the two groups of winding drums 31 are fixedly connected to the front and rear output shafts of the bidirectional motor 30, and two groups of connecting ropes 32 are wound around the two groups of winding drums 31, and the four groups of connecting ropes 32 are connected to the two groups of sampling heads 27, and a through hole 33 is opened in the right end of the collecting box 6, and the lower ends of the two groups of sampling heads 27 are connected to the two groups of through holes 33 Aligned, two groups of liquid collecting tanks 35 are installed through threads in the right end of the collecting box 6, and the two groups of liquid collecting tanks 35 are movably connected with the two groups of straws 25. After the collecting box 6 sinks under the water surface, the two-way motor 30 rotates to drive the two groups of winding drums 31 to rotate to loosen the four groups of connecting ropes 32, and the two groups of sampling heads 27 connected to the two groups of water pumps 26 pop out from the sampling cavity 24 under the action of the restoring force of the two groups of springs 29, and the two groups of sampling heads 27 pop out and insert into the river, and then the two groups of water pumps 26 extract river water through the two groups of sampling heads 27, and the collected water is collected in the two groups of liquid collecting tanks 35, and the collected river water is subsequently accurately tested through the two groups of liquid collecting tanks 35, and the two groups of liquid collecting tanks 35 can be disassembled from the right end of the collecting box 6, so that the two groups of liquid collecting tanks 35 filled with river water can be taken out for laboratory testing, and different substances in the river water can be tested.

[0040] Furthermore, the two groups of water pumps 26 are connected to the two groups of sampling heads 27 by a foldable hose, and the two groups of fixing rings 28 are fixedly connected to the upper end of the foldable hose at the lower end of the two groups of water pumps 26. This structure is based on the pipe material between the two groups of water pumps 26 and the two groups of sampling heads 27, so that when the two groups of sampling heads 27 are popped out from the sampling cavity 24 and inserted into the river, the two groups of water pumps 26 remain motionless in the sampling cavity 24, and the foldable hose between the two groups of water pumps 26 and the two groups of sampling heads 27 will be stretched and extended, so that when the two groups of sampling heads 27 are inserted into the water surface, the two groups of water pumps 26 will not be driven down together, thereby increasing the extension distance between the two groups of sampling heads 27 and the water pumps 26.

[0041] Furthermore, waterproof pads 34 are fixedly installed in the two groups of through holes 33. The middle parts of the two groups of waterproof pads 34 are cross-shaped openings. The two groups of waterproof pads 34 are made of rubber material. This structure uses the waterproof pads 34 installed in the two groups of through holes 33, so that when the two groups of sampling heads 27 rise upward and enter the straw 25, the waterproof pads 34 in the two groups of through holes 33 are closed at the moment the sampling heads 27 are pulled out, thereby preventing river water from entering the sampling cavity 24 through the two groups of through holes 33. When the two groups of waterproof pads 34 seal the two groups of through holes 33, the two groups of waterproof pads 34 will not cause obstruction when the two groups of sampling heads 27 pop out of the sampling cavity 24.

[0042] Furthermore, the inner wall diameter of the two groups of through holes 33 is larger than the outer wall diameter of the lower end of the two groups of sampling heads 27, and the outer wall diameter of the upper end of the two groups of sampling heads 27 is larger than the outer wall diameter of the lower end. This structure is based on the inner wall diameter of the two groups of through holes 33 and the upper and lower diameters of the two groups of sampling heads 27, so that the two groups of sampling heads 27 will not be completely popped out of the two groups of through holes 33 when they pop out of the sampling cavity 24, thereby improving the length limit for the two groups of sampling heads 27 to pop out.

[0043] Working principle: When using the drone body 1, Figure 2 , Figure 5 and Figure 8 As shown, the two groups of card blocks 8 at the upper end of the collection box 6 are inserted into the two groups of card slots 7 at the lower side of the fixing plate 5. After the two groups of card blocks 8 are fully inserted into the two groups of card slots 7, the two groups of baffles 9 are turned over to close the right end openings of the two groups of card slots 7. After rotating the two groups of bolts 10, the two groups of card blocks 8 and the two groups of baffles 9 are inserted, and then the two groups of card blocks 8 are fixed in the two groups of sampling heads 27. Then the drone body 1 flies through the four groups of blades 2. The drone body 1 detects and determines the floating objects on the river surface through the camera 3. The drone body 1 descends to make the collection box 6 contact with the water surface, and the lower end of the collection box 6 sinks into the water surface. Figure 3 , Figure 4 and Figure 6As shown, the first motor 23 is started, and the output shaft of the first motor 23 drives the first synchronous wheel 19, the second synchronous wheel 20 and the third synchronous wheel 21 to rotate. The rotation of the first synchronous wheel 19 drives the paddle wheel 11 to rotate. The paddle wheel 11 rotates to push up the floating objects on the water surface, and as the paddle wheel 11 rotates, the floating objects are pushed into the collection box 6. In addition, according to the composition material of the paddle wheel 11, when the paddle wheel 11 rotates under the water surface, when the paddle wheel 11 rotates, the water flow will not cause too much resistance to the paddle wheel 11, and will not greatly push the flow of the river, so that the floating objects on the water surface will not be pushed up while the water is scraped up, and the rotation of the paddle wheel 11 will not generate thrust to move the collection box 6 on the water surface. While the paddle wheel 11 collects the floating objects on the water surface at a rotating speed, the drone body 1 and the four sets of blades 2 move parallel to the water surface, so that the drone body 1 drives the collection box 6 to move on the water surface, and then The rear paddle wheel 11 rotates and moves with the collection box 6 to rotate and collect the floating objects on the water surface. The second synchronous wheel 20 drives the two groups of first rotating shafts 12 and the conveyor belt 13 to rotate. The conveyor belt 13 rotates to transport the floating objects dialed into the collection box 6 by the paddle wheel 11, and the conveyor belt 13 inputs the floating objects into the right end of the collection box 6. The third synchronous wheel 21 rotates to drive the second rotating shaft 14 and the first bevel gear 15 to rotate. The first bevel gear 15 drives the meshing third rotating shaft 16, the second bevel gear 17 and the shifting rod 18 to rotate. The shifting rod 18 rotates to shift the floating objects transported into the right end of the collection box 6 by the conveyor belt 13, thereby evenly leveling the floating objects entering the right end of the collection box 6, so that after the floating objects are collected in the collection box 6, the weight of each position is kept uniform, and the collection and cleaning of the floating objects drifting on the river surface can be completed. When the lower end of the collection box 6 sinks below the water surface, such as Figure 7 , Fig. 9 and Fig.10As shown, the output shafts at the front and rear ends of the bidirectional motor 30 drive the two sets of winding drums 31 to rotate, and the two sets of winding drums 31 rotate to loosen the four sets of connecting ropes 32 wound on the surface. After the four sets of connecting ropes 32 are loosened, the two sets of sampling heads 27 pop out under the action of the restoring force of the two sets of springs 29, and the two sets of sampling heads 27 pop out from the two sets of through holes 33 and insert into the water surface, and then the two sets of water pumps 26 extract river water through the two sets of sampling heads 27, and the river water extracted by the two sets of water pumps 26 is collected into the two sets of liquid collecting tanks 35 through the two sets of suction pipes 25, so as to facilitate the subsequent detection of the river water. The bidirectional motor 30 drives the two sets of winding drums 31 to rotate in the reverse direction, and then The four groups of connecting ropes 32 are rolled up and the two groups of sampling heads 27 are lifted up and enter the sampling chamber 24, which is convenient for next use. The lower side of the right end of the collecting box 6 is hollowed out. When the collecting box 6 rises from under the water surface along with the drone body 1 and the four groups of blades 2, when the lower side of the collecting box 6 moves to the water surface and the water is separated, the river water in the collecting box 6 flows in from the hollow part on the lower side of the collecting box 6, and the moisture contained in the floating objects collected in the collecting box 6 seeps out through the hollow part on the lower side of the collecting box 6, so that the drone body 1 will not reduce the flight distance due to excessive water load when driving the collecting box 6 to fly. The above is the entire working principle of the present invention.
