Detailed implementation manner

[0024] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0025] Embodiment: As Figures 1-5 shown, the present utility model provides a technical solution for an underwater sampling device based on marine ecological restoration, including a housing 1. A support plate 2 is installed at the inner bottom of the housing 1. A sample storage box 3 is stacked on the top of the support plate 2. A connector 4 is connected to one side of the outside of the sample storage box 3. A water delivery pipe 5 is installed on one side of the top of the support plate 2. A water distribution valve 6 is evenly connected to one side of the water delivery pipe 5. The water outlet end of the water distribution valve 6 is rotatably connected to the adjacent connector 4. An air vent hole 7 is penetrated and opened at the bottom of the outside of the water delivery pipe 5. A water inlet valve 8 is installed at the top of one side of the housing 1. The water inlet end of the water inlet valve 8 is connected to a water inlet pipe 9. The water outlet end of the water inlet valve 8 is connected to the top of one side of the water delivery pipe 5;

[0026] An isolation box 17 is installed outside the housing 1 on the outside of the water inlet valve 8. An isolation net 18 is installed at the top end of the isolation box 17. The isolation box 17 and the isolation net 18 can isolate weeds and other sundries in the sea water to prevent weeds and other sundries from blocking the water inlet pipe 9;

[0027] A sealing plug 10 is slidably installed inside the water delivery pipe 5. A counterweight 11 is connected to the bottom of the sealing plug 10. A waterproof cover 12 is installed at the top of the water delivery pipe 5. A driving motor 16 is installed at the top of one side inside the housing 1. The output end of the driving motor 16 is connected to a wire winding roller 13. A pulling rope 14 is wound around the outside of the wire winding roller 13. The movable end of the pulling rope 14 penetrates through the waterproof cover 12 and is connected to the top of the sealing plug 10. The outside of the sealing plug 10 is closely attached to the inside of the water delivery pipe 5 to prevent water from overflowing from the joint between the sealing plug 10 and the water delivery pipe 5. The inner side of the water delivery pipe 5 and the outside of the sealing plug 10 are both smooth curved surfaces, which reduces the frictional resistance between the water delivery pipe 5 and the sealing plug 10. Under the action of the gravity of the counterweight 11, the sealing plug 10 can be driven to smoothly slide inside the water delivery pipe 5;

[0028] A sealing ring 15 is clamped at the connection between the waterproof cover 12 and the pull rope 14. The sealing ring 15 can prevent the seawater in the water delivery pipe 5 from overflowing from the joint between the pull rope 14 and the waterproof cover 12;

[0029] The input ends of the water distribution valve 6, the water inlet valve 8 and the drive motor 16 are electrically connected to the output end of the external controller, and the input end of the external controller is electrically connected to the output end of the external power supply;

[0030] A counterweight plate 19 is installed at the bottom of the outer side of the housing 1, a sealing cover 20 is installed on the top of the housing 1, and a connecting rope 21 is connected to the middle of the top of the sealing cover 20;

[0031] Fixing sleeves 22 are installed on both outer sides of the sample storage box 3. Limiting plates 23 are evenly installed on the top of the support plate 2 on the outer side of the sample storage box 3. Fixing plates 24 are installed on both sides of the top of the support plate 2. Fixing holes 25 are evenly formed through one side of the fixing plates 24. Mounting plates 26 are arranged on one side of the fixing plates 24. Fixing heads 27 are evenly welded on one side of the mounting plates 26. The fixing heads 27 penetrate through the adjacent fixing holes 25 and are embedded in the adjacent fixing sleeves 22;

[0032] A magnetic block is installed at the top of the fixing head 27. The outer side of the sample storage box 3 is in close contact with the inner side of the limiting plate 23. The fixing sleeve 22 is made of iron. When the fixing head 27 is embedded in the fixing sleeve 22, with the limitation of the limiting plate 23, the sample storage box 3 can be fixed to prevent the sample storage box 3 from moving. Under the action of magnetic force, the magnetic block can make the fixing head 27 more firmly fixed in the fixing sleeve 22 and prevent the fixing head 27 from moving out of the fixing sleeve 22 when the housing 1 shakes.

[0033] The working principle and usage process of the present utility model: The staff holds the connecting rope 21 and puts the housing 1 into the sea water. The counterweight plate 19 drives the housing 1 to descend. The sealing plug 10 is located at the top inner side of the water delivery pipe 5. The water inlet valve 8 and the water distribution valve 6 are in the closed state at this time;

[0034] When the housing 1 descends to the specified sampling position, the water inlet valve 8 and the water distribution valve 6 at the topmost part are opened. After the seawater is filtered by the isolation net 18, it enters the inside of the water delivery pipe 5 from the water inlet pipe 9. At the same time, the drive motor 16 is started. The drive motor 16 drives the winding roller 13 to rotate and release the pull rope 14. Under the action of the gravity of the counterweight 11 and the pressure of the seawater, the sealing plug 10 is driven to slide down inside the water delivery pipe 5. When the sealing plug 10 slides down to the bottom of the water inlet end of the topmost water distribution valve 6, the drive motor 16 pauses to operate. The water distribution valve 6 connected to the topmost sample storage box 3 is opened. The seawater enters the inside of the sample storage box 3 from the inside of the water delivery pipe 5 through the water distribution valve 6 and the connecting head 4;

[0035] At regular intervals, the water distribution valve 6 connected to it closes, and the drive motor 16 drives the winding roller 13 to rotate. The winding roller 13 winds the pulling rope 14, and the pulling rope 14 drives the sealing plug 10 to rise, discharging the remaining seawater in the water delivery pipe 5 successively through the water inlet valve 8 and the water inlet pipe 9. After discharging the remaining water, the water inlet valve 8 closes;

[0036] The connecting rope 21 is lengthened, and the housing 1 continues to descend. When the housing 1 descends to the specified sampling position, the water inlet valve 8 and the water distribution valve 6 connected to the second-layer sample storage box 3 are opened, and the above process is repeated. Seawater enters the interiors of all the sample storage boxes 3 successively, thereby sampling seawater at different depths;

[0037] After sampling is completed, the housing 1 is retracted under the connection action of the connecting rope 21. After the housing 1 is retracted, the sealing cover 20 is opened, the mounting plate 26 is pulled to move the fixing head 27 out of the fixing sleeve 22 and the fixing hole 25, and at the same time the connecting head 4 is separated from the water distribution valve 6. Then the sample storage boxes 3 are taken out of the limiting plate 23 in turn. After taking them out, the sample storage boxes 3 are tilted to discharge the seawater from the position of the connecting head 4, completing the final sampling.

[0038] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
