Description

Technical Field

[0001] The invention relates to the technical field of remote-controlled unmanned boats, and in particular to a remote-controlled unmanned boat tidal flat comprehensive sample collection device. Background Art

[0002] A remote-controlled unmanned boat is a surface vehicle that is remotely controlled through radio and other media. It plays an important role in professional fields such as water quality monitoring, pollution prevention and control, water depth and landform measurement, water conservancy parameter investigation, surface garbage cleaning, facility inspection, marine scientific research, water monitoring and emergency rescue.

[0003] Remote-controlled unmanned boats are used for sampling in water quality monitoring and pollution prevention and control. Compared with the traditional shore sampling method, remote-controlled unmanned boats can quickly and accurately reach the preset sampling points, such as the center of the water area, reefs, aquatic plant growth areas, etc., and conduct sampling according to the preset procedures. It is especially suitable for tidal flats that are difficult for staff to reach and the sampling environment is relatively harsh;

[0004] However, in actual use, since the mudflats are located in the tidal zone between the high tide and low tide of the coastal area, under the action of the tide, the upper part of the mudflats is often exposed to the water surface while the lower part is often submerged. This leads to a certain difference in water level at the same sampling point at different times. When the water level is low, the sampling pipeline of the existing remote-controlled unmanned boat is easily inserted into the soft mud or sandy mud brought by the tide. Since the suction required for sampling is generally provided by a water pump, the particles in the soft mud and sandy mud will enter the water pump with the water flow, and wear the impeller during the operation of the water pump, which may cause damage to the impeller. Summary of the invention

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a remote-controlled unmanned boat tidal flat comprehensive sample collection device. 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 making creative work are within the scope of protection of the present invention.

[0064] In order to solve the problem that the tidal flat is located in the tidal zone between the high tide and the low tide of the coastal area, the upper part of the tidal flat is often exposed to the water surface while the lower part is often submerged under the action of the tide, which leads to a certain difference in water level at the same sampling point at different times. When the water level is low, the sampling pipeline of the existing remote-controlled unmanned boat is easily inserted into the soft mud or sandy mud brought by the tide. Since the suction force required for sampling is generally provided by a water pump, the particles in the soft mud and sandy mud will enter the water pump with the water flow and wear the impeller during the operation of the water pump, which may cause damage to the impeller. The present invention proposes a remote-controlled unmanned boat tidal flat comprehensive sample collection device, such as Figure 1 - Fig.18 As shown:

[0065] The invention comprises a remote-controlled unmanned boat body 10 traveling on a tidal flat water surface, a combination chamber 11 is provided on the remote-controlled unmanned boat body 10, a shell 12 is installed in the combination chamber 11, a sampling mechanism 20 is arranged inside the shell 12, the sampling mechanism 20 comprises a vane pump 21 installed in the shell 12 and a conduit 23 arranged below the vane pump 21, a sampling tube 24 which can be raised and lowered is arranged in the conduit 23, and a water outlet end of the vane pump 21 is connected to a storage chamber 22;

[0066] A storage chamber 121 that penetrates the combined chamber 11 is provided at the bottom of the shell 12, and a conduit 23 is provided in the storage chamber 121. When the remote-controlled unmanned boat body 10 moves to the sampling point, if the water level is high at this time, the impeller pump 21 can be directly started, and the sample is directly sucked in through the storage chamber 121, and after passing through the impeller pump 21, enters the storage chamber 22 for storage.

[0067] The storage chamber 121 is also provided with an excavation mechanism 30, which includes an elevating excavation drill bit 34, and the excavation drill bit 34 leaves a hole on the beach when it descends;

[0068] A rotating mechanism 40 is provided in the middle of the sampling tube 24. The rotating mechanism 40 includes an internally threaded sleeve rod 43 provided in the middle of the sampling tube 24. The bottom of the internally threaded sleeve rod 43 is connected to the excavation drill bit 34. When the water level is low, the excavation drill bit 34 is lowered to leave a hole on the surface of the beach. Under the action of gravity-driven water flow and distribution, water on other flat positions will fill the deep depression area and flow into the hole produced by the excavation drill bit 34. At this time, the sampling tube 24 that descends together with the excavation drill bit 34 can extend into the hole and extract the water sample in the hole, thereby avoiding the sampling tube 24 from being directly inserted into the beach bed with the lifting and lowering, so as to reduce the suction of soft mud or sand mud during the sampling process, reduce the occurrence of particles in the soft mud and sand mud entering the impeller pump 21 with the water flow, and improve the service life of the impeller pump 21. The sample sucked by the impeller pump 21 is injected into the storage chamber 22;

[0069] After the sample collection is completed, the excavation drill bit 34 rises and moves out of the hole, while the internal threaded sleeve rod 43 and the sampling tube 24 are retracted into the guide tube 23, so as to prevent the remote control unmanned boat body 10 from contacting and damaging the mudflat bottom during the driving process and destroying the driving stability of the remote control unmanned boat body 10. The remote control unmanned boat body 10 carries the sample to the shore staff to complete the sampling;

[0070] At high tide, due to the effect of the tide, the water body will be subjected to greater gravitational force, thereby generating greater fluctuations and forming larger waves. At this time, even if the water level at the sampling point is high and there is no need for the excavation drill bit 34 to drill a hole in the mudflat bottom bed, the excavation drill bit 34 can still be lowered and inserted into the mudflat bottom bed to achieve the purpose of stabilizing the hull and ensure the stability of the sampling process.

[0071] In order to enable the excavation drill bit 34 to be raised and lowered, as Figure 3As shown, the excavation mechanism 30 also includes a hydraulic push rod 31 arranged in the storage cavity 121 and a mounting frame 32 arranged on the extended end of the hydraulic push rod 31. The mounting seat 33 is rotatably embedded in the multiple mounting frames 32, and the excavation drill bit 34 is installed on the mounting seat 33. By starting the hydraulic push rod 31, the hydraulic push rod 31 is extended and the mounting seat 33 is driven to descend through the mounting frame 32. The excavation drill bit 34 installed on the mounting seat 33 is then lowered to be inserted into the tidal flat bottom bed and complete the drilling.

[0072] In the actual operation process, since the material composition of the tidal flat bottom is complex, including rocks, beaches, mud flats and other types, in order to make the excavation drill bit 34 more easily inserted into the tidal flat bottom and produce holes, such as Figure 4 , Figure 5 As shown, the excavation drill bit 34 can also be rotated by a rotating mechanism 40, and the rotating mechanism 40 also includes a fixing frame 41 arranged on the inner wall of the guide tube 23, a threaded rod 42 is fixedly mounted on the fixing frame 41, and an internal threaded sleeve rod 43 is sleeved on the threaded rod 42, and the inner wall of the internal threaded sleeve rod 43 and the threaded rod 42 are meshed with each other;

[0073] The bottom end of the internal threaded sleeve rod 43 is connected to the mounting seat 33. When the mounting seat 33 descends, the internal threaded sleeve rod 43 is driven to move and rotate on the surface of the threaded rod 42, so that the excavation drill bit 34 rotates and excavates the hole while descending;

[0074] When the excavation drill bit 34 descends, the excavation drill bit 34 pulls the internal threaded sleeve rod 43 through the mounting seat 33, and the internal threaded sleeve rod 43 can drive the sampling tube 24 to move inside the catheter 23 and insert into the hole for sampling. While the internal threaded sleeve rod 43 moves on the surface of the threaded rod 42, the internal threaded sleeve rod 43 can rotate under the action of the thread, so that the internal threaded sleeve rod 43 drives the excavation drill bit 34 to rotate and insert into the tidal flat bottom bed through the mounting seat 33. When rotating and inserting, the contact mode between the excavation drill bit 34 and the tidal flat bottom bed changes from static friction to dynamic friction, thereby achieving the purpose of reducing friction resistance and making drilling easier.

[0075] Furthermore, the surface of the excavation drill bit 34 is provided with spiral concave patterns, such as Figure 1 and Fig.13 As shown, the texture can reduce the direct contact area between the excavation drill bit 34 and the hole wall, thereby reducing friction, and during the drilling process, the mud and sand are discharged through the concave texture to prevent the mud and sand from accumulating in the hole;

[0076] When drilling a hole, the excavation drill bit 34 can also leave spiral lines on the hole wall under the effect of the spiral concave lines, so as to improve the stability of the inner wall of the hole and reduce the occurrence of hole collapse;

[0077] The excavation drill bit 34 will also exert pressure on the bottom bed during the drilling process. Under the action of the displacement of soft mud and sand mud, an annular bulge will be formed around the excavation drill bit 34, such as Figure 7 As shown, the natural barrier formed by the ridges can block the large particles of impurities carried by the water as it flows into the holes.

[0078] In order to prevent the rotation of the internal threaded sleeve 43 from affecting the lifting and lowering of the sampling tube 24, Figure 5 As shown, a plurality of first slide grooves 231 are vertically opened on the inner wall of the conduit 23, and a plurality of first sliding blocks 241 which can be embedded in the first slide grooves 231 are arranged on the outer wall of the sampling tube 24;

[0079] A limit ring 44 is provided in the middle of the sampling tube 24, and the internal threaded sleeve 43 is rotatably embedded in the limit ring 44. Through the cooperation of the first slider 241 and the first slide groove 231, the sampling tube 24 can only be lifted and lowered inside the catheter 23 but cannot be rotated. Through the cooperation of the limit ring 44, the internal threaded sleeve 43 can rotate under the restriction of the limit ring 44 and can drive the sampling tube 24 to be lifted and lowered synchronously.

[0080] Since the material composition of the tidal flat bottom is complex, it is difficult to ensure the stability of the sampling operation by relying solely on the spiral pattern left by the excavation drill bit 34 on the inner wall of the hole. Therefore, a connecting rod 45 is provided on the inner wall of the mounting seat 33, and the middle part of the connecting rod 45 is connected to the internal threaded sleeve rod 43;

[0081] An anti-collapse mechanism 60 is arranged around the internal thread sleeve 43, and the anti-collapse mechanism 60 includes a plurality of support plates 64 arranged around the internal thread sleeve 43 and a second slide groove 61 provided on the connecting support rod 45, a second slider 62 is slidably embedded in the second slide groove 61, and a plug rod 63 is connected to the top of the second slider 62, and the top of the plug rod 63 is connected to the support plate 64;

[0082] When the excavation drill bit 34 completes the drilling operation, the second slide block 62 can slide under the restriction of the second slide groove 61 and drive the support plate 64 to move through the insertion rod 63. Multiple support plates 64 can be deployed. When the hole collapses, the support plates 64 can block and support the mud and sand, stabilize the inner wall of the hole, and reduce the sampling area of ​​mud and sand close to the center of the equipment;

[0083] When the sampling operation is completed, the second slider 62 moves in the reverse direction to drive the plurality of support plates 64 to close together and retract them into the conduit 23 together with the internal threaded sleeve rod 43 .

[0084] In order to be able to control the opening and closing of the support plate 64, as Figure 6 , Figure 8-Figure 12As shown, the position of the support plate 64 is adjusted by the adjustment mechanism 50, which includes a mounting groove 54 provided at the bottom of the internal threaded sleeve rod 43, a connecting member 55 rotatably embedded in the mounting groove 54, and a turntable 56 rotatably embedded on the mounting seat 33, and the surface of the turntable 56 is provided with guide grooves 57 having the same number as the insertion rod 63, and the insertion rod 63 passes through the guide groove 57 and fits with the inner wall of the guide groove 57;

[0085] At the same time, an arc groove 431 is provided on the surface of the internally threaded sleeve 43, and a clamping block 551 penetrating the arc groove 431 is provided on the surface of the connecting member 55. A clamping groove 561 that interlocks with the clamping block 551 is provided on the inner side of the turntable 56. By rotating the connecting member 55, the connecting member 55 drives the turntable 56 to rotate through the clamping block 551 and the clamping groove 561. The clamping block 551 moves in the arc groove 431, so it will not affect the internally threaded sleeve 43. When the turntable 56 rotates, the insert rod 63 is pushed through the guide groove 57, so that the insert rod 63 drives the second sliding block 62 to move horizontally along the length direction of the second sliding groove 61, thereby achieving the purpose of adjusting the position of the support plate 64.

[0086] Among them, the adjustment mechanism 50 also includes an installation chamber 51 opened in the middle of the excavation drill bit 34, and a sealing ring 53 is arranged on the top of the installation chamber 51 to prevent water seepage. A power source is arranged inside the installation chamber 51. The power source is a motor 52, model RS550, which is a low-speed, high-torque 24V DC motor, which is remotely controlled by a control unit. The output end of the motor 52 passes through the sealing ring 53 and is connected to the connecting piece 55.

[0087] In order to further improve the effect of the support plate 64 in blocking the collapse of sediment, Figure 14-18 As shown, a blocking mechanism 70 is connected between adjacent support plates 64, and the blocking mechanism 70 includes a connecting shaft 78 rotatably arranged on both sides of the support plate 64 and a connecting rod 77 arranged between two adjacent support plates 64, and a rubber strip 71 is connected between the connecting rod 77 and the connecting shafts 78 on both sides, and the rubber strip 71 can be stretched and deformed and has a through hole on the surface;

[0088] When the support plate 64 is unfolding, it can cooperate with the connecting shaft 78 and the connecting rod 77 to pull the rubber strip 71 and make it elastically deformed. The stretched and extended rubber strip 71 can fill the gap between adjacent support plates 64, thereby achieving the purpose of further improving the barrier capacity of mud and sand.

[0089] At the same time, in order to guide the rubber strip 71 to shrink inward when the support plates 64 are closed together, so that it can rise together with the support plates 64 and the internally threaded sleeve rod 43 and be received in the conduit 23, the blocking mechanism 70 also includes a plurality of mounting blocks 72 arranged on the mounting seat 33, the mounting blocks 72 are provided with guide rails 73, and the inner wall of the guide rails 73 is provided with guide rods 74, a movable block 75 is slidably embedded in the guide rails 73, and a spring 76 is wound around the guide rod 74, and the two ends of the spring 76 are respectively connected to the movable block 75 and the inner wall of the guide rail 73;

[0090] The connecting rod 77 is mounted on the movable block 75 and passes through the top of the guide rail 73;

[0091] The plurality of guide rails 73 are connected to each other through a combination ring 731, and the combination ring 731 is sleeved and installed on the surface of the internal thread sleeve rod 43;

[0092] When the support plate 64 is unfolded and pulls the rubber strip 71 to generate elastic deformation, the rubber strip 71 also pushes the connecting rod 77 outward, so that the connecting rod 77 drives the movable block 75 to move horizontally along the straight line direction of the guide rail 73, and when moving, it cooperates with the guide rod 74 to pull the spring 76 and generate elastic deformation;

[0093] When the support plates 64 are closed together, the connecting rod 77 is reset under the pull of the spring 76 elastically recovering, and the connecting rod 77 passes through the gap between the two support plates 64 and moves closer to the internal threaded sleeve 43, so that the rubber strip 71 is recovered to the inner side of the support plate 64 together with the connecting rod 77 while the elastic deformation is recovered, thereby ensuring that the rubber strip 71 is located in the cavity between the support plate 64 and the internal threaded sleeve 43 after the support plates 64 are folded.

[0094] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a remote-controlled unmanned boat tidal flat comprehensive sample collection device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
