Technical Field

[0001] The invention relates to the technical field of water environment detection, and in particular to a portable marine water environment DNA detection device. Background Art

[0002] Water pollution refers to the phenomenon that pollutants entering a water body exceed the water's self-purification capacity, causing changes in the water's chemical, physical, biological or radioactive properties, thereby affecting the effective use of water, endangering human health or damaging the ecological environment, and causing water quality deterioration. For this reason, it is necessary to regularly test the water environment to detect whether there is pollution.

[0003] Ocean water is the general term for the largest body of water on Earth, referring to the vast waters on the Earth's surface that are separated by continents and connected to each other. The ocean is almost full of organisms, which are divided into plankton, swimming organisms and benthic organisms according to their lifestyles. In order to maintain the living environment of these organisms, water environment workers need to conduct DNA testing on the ocean water environment regularly. DNA testing requires the use of dedicated ocean water environment DNA testing equipment.

[0004] The existing marine water environment DNA detection device first uses an extraction device to sample the water, and then takes it to the laboratory for detection through the water environment DNA detection device. The sampled water and drugs are first mixed to lyse the bacteria and elute the DNA, and then the detection process is carried out.

[0005] The water environment DNA detection device is usually placed directly on the hull or on a supporting tool with the help of a supporting tool for easy operation by personnel. However, it is inconvenient to find the supporting tool and placing it too low is not conducive to personnel operation. At the same time, it is easy to be damaged after being hit by other objects, and then it cannot be used, thus shortening its service life. Summary of the invention

[0006] The purpose of the present invention is to provide a portable marine water environment DNA detection device to solve the problem in the above background technology that the device is usually placed directly on the hull or placed on a supporting tool with the help of a supporting tool for personnel to operate, but it is inconvenient to find the supporting tool, and it is not conducive to personnel operation if placed too low. At the same time, after being hit by other objects, it is easy to be damaged and then cannot be used, thus shortening the service life.

[0007] To achieve the above object, the present invention provides the following technical solution: a portable marine water environment DNA detection device, comprising a shell, a cover body is installed on the top of one side of the shell body through a hinge, and a DNA detector is assembled on the cover body, and a lock is provided at one end of the shell body and the cover body away from the hinge;

[0008] Both ends of the cover body away from the hinge are provided with L-shaped sliding grooves, and the outside of the cover body is slidably assembled with a handle through the L-shaped sliding groove. The cover body forms a supporting structure through the handle and the lock, so that the cover body supports the DNA detector upward.

[0009] By adopting the above technical solution, after the shell and the cover are locked and merged by the lock, the DNA detector is stored in the shell and the cover to play a protective role.

[0012] Preferably, a bracket is fixed to the inner wall of the shell below the rotating frame, and a servo motor is installed below the bracket, and the output end of the servo motor passes through the bracket and is fixedly connected to the bottom of the rotating frame.

[0013] By adopting the above technical solution, the servo motor is started, and the output end of the servo motor drives the rotating frame to rotate when it rotates forward and reversely, so as to mix the substances in the sampling bottle and improve the accuracy of subsequent detection.

[0014] Preferably, a sleeve plate is sleeved on the outside of the rotating frame, and an electric push rod is installed between the bottom of one end of the sleeve plate and the bottom end of the shell.

[0015] By adopting the above technical solution, the electric push rod unfolds the sleeve and moves up, and the sleeve supports the flap to prevent the flap from tilting and opening, which is not conducive to the mixing of liquids in the sampling bottle. The electric push rod shrinks, the sleeve moves to the bottom of the flap, and the flap tilts to facilitate personnel to take out the sampling bottle.

[0016] Preferably, a sampling bottle is assembled in the placement hole, and a shunt tube is arranged above the rotating frame.

[0017] By adopting the above technical solution, the sampled liquid can flow into each sampling bottle through the shunt tube.

[0019] By adopting the above technical solution, when the ring gear rotates, gear one and gear two rotate, and the movable plate is pushed by the connecting rod, and the groove is moved out of the universal wheel to facilitate the movement of the shell. Conversely, the groove is received in the universal wheel, which protects the groove.

[0020] Preferably, a water pump is installed on the left side of the shell, and a connecting pipe is connected between the output end of the water pump and the diversion pipe, the input end of the connecting pipe is connected to a sampling hose, and the sampling hose runs through the left side of the shell.

[0021] By adopting the above technical solution, the water pump is started to perform sampling processing, so that the liquid flows into the diversion pipe along the sampling hose and the connecting pipe, and is diverted through the diversion pipe.

[0022] Preferably, one end of the sampling hose away from the connecting pipe is fixedly connected to a sampling assembly, and the sampling assembly includes a sampling cylinder, and the sampling cylinder is arranged above the bracket.

[0023] By adopting the above technical solution, the sampling tube is dropped into the river water under its own gravity, so as to sample the water body at a later time.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. After the cover rotates, the handle rotates, and the cover and the handle are placed at right angles. The cover is placed in an erected state through the handle and the shell. The cover is used to support the DNA detector without being placed on the ship or other supporting frames found, and it is convenient for staff to operate.

[0030] 2. After the cover and the shell are combined, the DNA detector is stored in the shell and the cover. The shell and the cover protect the DNA detector to avoid damage caused by impact from external objects during carrying.

[0031] 3. After the flap and the rotating frame are vertically assembled, the sampling bottles are placed in limited positions, and the sleeve plate is moved up and down by the electric push rod. The flap is positioned by the electric push rod to improve the stability of the sampling bottles placed on the rotating frame. After the electric push rod retracts the sleeve plate and moves down, the flap is rotated outward to open, so as to facilitate the removal of the sampling bottles from the rotating frame.

[0032] 4. After the servo motor is started, the output shaft of the servo motor drives the rotating frame to rotate back and forth, so as to further mix the substances in the sampling bottles assembled in the placement holes, thereby improving the accuracy of water inspection.

[0033] 5. When the output shaft of the servo motor rotates back and forth, the ring gear actuates gear two, and gear two actuates gear one to rotate. The connecting rod and gear one cooperate with the connecting rod and gear two to drive the movable plate to move, and the universal wheel extends out from one side of the shell, and the universal wheel facilitates the movement of the shell, thereby facilitating carrying.

[0034] 6. When sampling water, the liquid is lifted up and the filter screen is unfolded, allowing the liquid to flow into the sampling hose. When the sampling tube is removed, the piston falls and the debris in the filter screen is removed, preventing large particles from flowing into the sampling hose and causing blockage. At the same time, it enters the water pump, which is not conducive to the operation of the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

L-shaped grooves 18 are provided at both ends of the cover 5 away from the hinge, and a handle 7 is slidably assembled on the outside of the cover 5 through the L-shaped groove 18. When moving, a person can hold the handle 7 and carry it by pulling, which improves the convenience of carrying. A short connecting shaft is fixed at the connection between the handle 7 and the cover 5, and the connecting shaft is located in the L-shaped groove 18. The handle 7 and the cover 5 are connected through the connecting shaft. The cover 5 forms a supporting structure through the handle 7 and the lock 8, so that the cover 5 supports the DNA detector 9 upward.

[0048] The sampling tube 63 is taken out from the storage slot 22, and the sampling hose 4 is wound out from the storage rack 23, and then the lock 8 is released, and the cover body 5 is rotated while first rotating the handle 7, and then the handle 7 is rotated, and the short connecting shaft of the handle 7 located in the L-shaped slide groove 18 is moved to contact the horizontal upper notch of the L-shaped slide groove 18, thereby improving the stability of the handle 7 when supporting the cover plate 5. Since the handle 7 and the shell 1 support the cover body 5, the DNA detector 9 is on the cover body 5 to facilitate the operation of the staff. At the same time, the staff puts some tools or supplies that need to be used on the cover body 5 for operation.

[0049] A rotating assembly 10 is provided in the housing 1 near one end of the lock 8. The rotating assembly 10 includes a rotating frame 101, and the top of the rotating frame 101 is provided with six groups of placement holes 102 distributed in a circular shape and at equal distances along the vertical center line of the rotating frame 101, and multiple sampling bottles 17 are placed thereon for sampling water bodies in different areas. A flap 106 is rotatably installed on the outer wall of the rotating frame 101 and near the top, at a position corresponding to the placement holes 102. The flap 106 is provided with an arc groove corresponding to the placement holes 102 near the center line of the rotating frame 101, so that the arc groove can limit the assembly of the sampling bottle 17. A bracket 103 is fixed to the inner wall of the housing 1 below the rotating frame 101. The bracket 103 is L-shaped when viewed from above, and the bracket 103 is fixedly connected to the inner wall of the housing 1. A servo motor 105 is installed below the bracket 103 , and the output end of the servo motor 105 passes through the bracket 103 and is fixedly connected to the bottom of the rotating frame 101 . The output shaft of the servo motor 105 drives the rotating frame 101 to reciprocate when it rotates forward and reversely, so as to mix the liquid in the sampling bottle 17 .

[0050] The servo motor 105 is started, the output end of the servo motor 105 rotates, the ring gear 104 rotates, and the gear 2 14 and the gear 1 13 are driven to rotate at the same time, and the movable plate 11 is driven to move with the cooperation of the connecting rod 12, so that the universal wheel 3 is moved out of the groove 2 in the shell 1. At this time, the universal wheel 3 is convenient for carrying in a pushing or pulling manner.

[0051] The housing 1 is provided with two grooves 2 below one side of the hinge. A movable plate 11 is provided near the left side of the housing 1. There is a gap between the movable plate 11 and the housing so that the movable plate 11 can move smoothly. The left side of the movable plate 11 penetrates the housing 1 and is equipped with a universal wheel 3. The groove 2 is used to store the universal wheel 3 to prevent the universal wheel 3 from entering the housing 1 and rainwater from entering the housing 1 through the groove 2 and damaging some parts in the housing 1. At the same time, the universal wheel 3 is stored in the groove 2, which protects the universal wheel 3 and prevents it from being damaged by collision with other objects during carrying. One side of the bracket 103 is rotated with gear 2 14 and gear 1 13, and the center lines of gear 2 14 and gear 1 13 are on the same straight line, and gear 1 13 and gear 2 14 are meshed with each other. A gear ring 104 is arranged on the outer wall near the bottom of the rotating frame 101, and the center lines of gear ring 104 and gear 2 14 are on the same straight line. Gear 1 13 and gear ring 104 are symmetrically distributed about the center point of gear 2 14 in an inclined plane. Gear 1 13, gear 2 14 and gear ring 104 are connected in a straight line L shape when viewed from above; gear ring 104 and gear 2 14 are meshed with each other, and gear 1 13, gear 2 14 and gear ring 104 form a transmission structure to reduce the number of motors used. Connecting rods 12 are rotated on both gear 13 and gear 2 14, and the other side of the connecting rod 12 is rotatably connected to the moving plate 11.

[0052] The servo motor 105 is started, the output end of the servo motor 105 rotates, the gear ring 104 rotates, and the gear 2 14 and the gear 1 13 are driven to rotate. The connecting rod 12 cooperates with the moving plate 11 to move, so that the universal wheel 3 moves out of the groove 2 in the housing 1. The servo motor 105 is started, and the output shaft of the servo motor 105 rotates forward and reversely to drive the rotating frame 101 to rotate, so as to mix the liquid in the sampling bottle 17.

[0053] A sampling bottle 17 is assembled in the placement hole 102. A small amount of liquid is stored in the sampling bottle 17, which is not fully filled. Since the diameters of the sampling bottle 17 and the placement hole 102 are equal, the firmness of the sampling bottle 17 inserted into the placement hole 102 is improved, thereby preventing the sampling bottle 17 from loosening and shaking during the rotation of the rotating frame 101, resulting in spillage of the liquid in the sampling bottle 17. A shunt pipe 21 is arranged above the rotating frame 101. The shunt pipe 21 is ring-shaped when viewed from above, and short water outlet pipes are connected to the position below the shunt pipe 21 and corresponding to the placement hole 102 at equal intervals, and the vertical center line of the short water outlet pipe coincides with the vertical center line of the placement hole 102. A water pump 19 is installed on the left side of the housing 1, and a connecting pipe 20 is connected between the output end of the water pump 19 and the shunt pipe 21. The connecting pipe 20 is made of hard material, and the connecting pipe 20 is attached to the inner wall of the housing 1 near the connection with the shunt pipe 21 to reduce the occupied space. At the same time, it does not affect the storage of the DNA detector 9 in the housing 1. The movable plate 11 is provided with a phenomenon for the movement of the sampling hose 4, and the movement of the movable plate 11 does not affect the sampling hose 4. The input end of the connecting pipe 20 is connected to the sampling hose 4, and the sampling hose 4 runs through the left side of the housing 1.

[0054] One end of the sampling hose 4 away from the connecting pipe 20 is fixedly connected to a sampling assembly 6 , and the sampling assembly 6 includes a sampling cylinder 63 . The sampling tube 63 is made of iron material and has a certain gravity, so it can be thrown into the water area. The sampling tube 63 is arranged above the bracket 103. A convex plate 62 is integrally formed on the outer wall of the sampling tube 63 near the top, and the connecting end of the sampling hose 4 and the sampling tube 63 is located on the convex plate 62. A piston 64 is arranged on the inner wall of the sampling tube 63. The piston 64 is pushed up by the water pressure and moves close to the top of the sampling tube 63, and is located above the connecting interface between the sampling tube 63 and the sampling hose 4, thereby avoiding the piston 64 from being blocked at the connecting interface between the sampling tube 63 and the sampling hose 4. A filter screen 61 is connected between the bottom end of the piston 64 and the bottom end of the inner wall of the sampling tube 63. The filter screen 61 is woven from ropes and has a deformation effect. When sampling liquid, the residue in the liquid is filtered through the filter screen 61 to avoid the residue from entering the sampling hose 4 and causing blockage, and at the same time to avoid the residue from entering the water pump, which is not conducive to the operation of the water pump. When the sampling tube 63 is lifted, the filter 61 is removed from the sampling tube 63 to shake out impurities for easy cleaning; the sampling tube 63 is thrown into the ocean water, the piston 64 moves upward under the impact of the liquid, and the liquid is filtered through the filter 61 to avoid clogging of the sampling hose 4 due to residues.

[0055] A storage rack 23 is fixed to the top of the cover 5, and the storage rack 23 is fixedly assembled by a hollow cylinder and a cross plate. A storage slot 22 is provided in the middle of the storage rack 23. The diameter of the bottom of the sampling tube 63 is equal to the diameter of the storage slot 22. The sampling tube 63 and the storage rack 23 are extruded and assembled through the storage slot 22, which improves the firmness of the sampling tube 63 assembled in the storage slot 22. At the same time, the sampling tube 63 is partially hidden by the storage rack 23, which can play a protective role, and the sampling hose 4 is wound around the storage rack 23 by rotation for storage.

[0056] The sampling tube 63 is thrown into the ocean water, the piston 64 moves upward under the impact of the liquid, the liquid is filtered through the filter screen 61, the water pump 19 is started, and the liquid flows into the sampling bottle 17 along the sampling hose 4, the connecting pipe 20 and the diversion pipe 21.

[0057] The outer surface of the rotating frame 101 is provided with a sleeve plate 16, and there is a gap between the sleeve plate 16 and the outer wall of the rotating frame 101, so that the rotation of the rotating frame 101 does not cause the sleeve plate 16 to rotate. An electric push rod 15 is installed between the bottom of one end of the sleeve plate 16 and the inner bottom end of the housing 1, and the expansion and contraction of the electric push rod 15 play a role in pushing up or moving down the sleeve plate 16; when the electric push rod 15 is started, the electric push rod 15 contracts the sleeve plate 16 and moves it down to the bottom of the flap 106, and the flap 106 is tilted to open so that the staff can take out the sampling bottle 17 from the rotating frame 101.

[0058] Working principle: When in use, first start the servo motor 105, the output end of the servo motor 105 rotates, the gear ring 104 rotates, and the gear 2 14 and the gear 1 13 are driven to rotate, and the movable plate 11 is driven to move with the cooperation of the connecting rod 12, so that the universal wheel 3 moves out of the groove 2 in the housing 1. At this time, the housing 1 can be easily carried by pushing or pulling through the universal wheel 3, without the need to carry it by hand;

[0059] Next, the sampling tube 63 is taken out from the storage slot 22, and the sampling hose 4 is wound out from the storage rack 23, and then the lock buckle 8 is released, and the cover body 5 is rotated while the handle 7 is rotated, and the handle 7 and the housing 1 support the cover body 5, and the DNA detector 9 is on the cover body 5. The sampling tube 63 is thrown into the ocean water, and the piston 64 moves upward under the impact of the liquid. The liquid is filtered through the filter screen 61, and the water pump 19 is started. The liquid flows into the sampling bottle 17 along the sampling hose 4, the connecting pipe 20 and the shunt pipe 21;

[0060] Drop some material into the sampling bottle 17 again, start the servo motor 105, and the output shaft of the servo motor 105 drives the rotating frame 101 to rotate when rotating forward and reverse, so as to mix the liquid in the sampling bottle 17;

[0061] Finally, the electric push rod 15 is started, and the electric push rod 15 retracts the sleeve 16 and moves it down to the bottom of the flap 106. The flap 106 is tilted to open so that the staff can take out the sampling bottle 17 from the rotating frame 101, and then perform detection and processing on the DNA detector 9, and transmit the detection result to the display on the DNA detector 9, so that the staff can know the water body DNA detection result and finally complete the use of the marine water environment DNA detection device.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
