Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present 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.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a ship paint detection sampling device includes a cylinder body 1 detachably installed on a bracket. The bottom end of the cylinder body 1 is threadedly and sealedly connected to a base 2, and a connecting pipe 3 is provided at the bottom of the base 2. A first one-way valve is provided at the corresponding position of the inner wall of the base 2 and the connecting pipe 3. A piston ring 6 is slidably and sealedly connected above the first one-way valve in the cylinder body 1. A plurality of first sealing rings 7 are sleeved on the outer wall of the piston ring 6. A second one-way valve is provided at the corresponding position of the top of the piston ring 6 and its central hole. An opening valve mechanism is provided through the piston ring 6. The opening valve mechanism is used to open the first one-way valve and the second one-way valve. A drain pipe 23 is fixedly communicated near the top end of the outer wall of the cylinder body 1. The top of the cylinder body 1 is flange-connected to a cover plate 17. A driving mechanism for driving the piston ring 6 to move up and down in the cylinder body 1 is installed on the cover plate 17. The connecting pipe 3 is connected to a suction pipe 28 through a first hose 27.

[0021] By adopting the above solution, when in use, after connecting the liquid discharge pipe 23 with the sample storage container through the second hose, the suction pipe 28 is inserted into the paint container, and then the piston ring 6 is driven by the driving mechanism to reciprocate up and down in the cylinder body 1. When the piston ring 6 moves upward, the second one-way valve closes and the first one-way valve opens to draw the paint into the space below the piston ring 6 in the cylinder body 1. When the piston ring 6 moves downward, the second one-way valve opens and the first one-way valve closes. At this time, the paint below the piston ring 6 cannot be discharged through the first one-way valve and can only move above the piston ring 6 through the central hole in the piston ring 6 and pass through the second one-way valve. After the piston ring 6 reciprocates, the paint liquid level in the cylinder body 1 will continuously rise until it is discharged into the paint container through the liquid discharge pipe 23. Therefore, by repeatedly operating the driving mechanism, sampling can be completed at one time. When the sampling is completed, by opening the valve mechanism to open the first one-way valve and the second one-way valve simultaneously, the remaining paint in the cylinder body 1 can be discharged back into the paint container, and the operation is simple and convenient.

[0022] Specifically, in combination with Figure 3 , in an embodiment of the present invention, the first one-way valve includes a lever 4 hinged to the inner wall of the base 2 through a first hinge seat. One end of the lever 4 facing the connecting pipe 3 is fixedly connected with a first valve plate 5. The second one-way valve includes a second valve plate 9 hinged to the top of the piston ring 6 through a second hinge seat 8. Rubber sheets are provided at the bottoms of the first valve plate 5 and the second valve plate 9.

[0023] Furthermore, the valve opening mechanism includes a guide rod 11 slidably passing through the piston ring 6. A perforation adapted to the guide rod 11 is provided on the piston ring 6 corresponding to the guide rod 11. The guide rod 11 passes through the perforation. The inner walls of the two open ends of the perforation are both embedded with second sealing rings 12. The inner wall of the second sealing ring 12 is in contact with the outer wall of the guide rod 11. Limiting pieces 13 are fixedly connected to the outer wall of the guide rod 11 near both ends. The two limiting pieces 13 are respectively located on the upper and lower sides of the piston ring 6. A spring 14 is sleeved on the outer wall of the guide rod 11 below the piston ring 6, and the spring 14 is located between the piston ring 6 and one of the limiting pieces 13. One end of the lever 4 away from the first valve plate 5 is located directly below the guide rod 11. An extension bar 10 is fixedly connected to the outer wall of the second valve plate 9 away from the second hinge seat 8, and the extension bar 10 is located directly above the guide rod 11.

[0024] After the piston ring 6 descends to an appropriate position within the cylinder body 1, the bottom end of the guide rod 11 will abut against the lever 4, causing the lever 4 to drive the first valve plate 5 to tilt upwards, such that the rubber sheet at the bottom of the first valve plate 5 disengages from the nozzle of the connecting pipe 3. Meanwhile, the top end of the guide rod 11 will come into contact with the bottom of the extension strip 10 and push the second valve plate 9 to rotate on the second hinge seat 8, thereby causing the rubber sheet at the bottom of the second valve plate 9 to disengage from the top surface of the piston ring 6, thus simultaneously opening the first check valve and the second check valve to discharge the remaining paint within the cylinder body 1 through the connecting pipe 3.

[0025] Specifically in combination with Figures 1 - 3 In an embodiment of the present invention, the driving mechanism includes a support 19 fixedly installed on the top of the cover plate 17. A pressure rod 20 is rotatably connected to the support 19. One end of the pressure rod 20 is rotatably connected to a connecting rod 16. The top of the piston ring 6 is fixedly connected to a connecting seat 15. An opening slot 18 is provided through the top of the cover plate 17. The bottom end of the connecting rod 16 passes through the opening slot 18 into the cylinder body 1 and is rotatably connected to the connecting seat 15.

[0026] By reciprocally rotating the pressure rod 20 on the support 19, the top end of the connecting rod 16 can be driven to move up and down within a certain range, thereby driving the piston ring 6 to slide up and down within the cylinder body 1, and the operation is simple and convenient.

[0027] Specifically in combination with Figure 1 and Figure 2 In an embodiment of the present invention, a limit pin 22 is detachably passed through the support 19 through a pin hole 21. When the pressure rod 20 is located below the limit pin 22, the bottom end of the guide rod 11 does not contact the lever 4.

[0028] Through the setting of the limit pin 22, the rotation angle of the pressure rod 20 can be limited on the support 19 to prevent the guide rod 11 from contacting the lever 4, thereby avoiding simultaneously opening the first check valve and the second check valve. Its structure is simple and can effectively avoid misoperation.

[0029] Specifically in combination with Figure 1 In an embodiment of the present invention, a connecting ring 24 is fixedly sleeved on the outer wall of the cylinder body 1. The bracket includes a support 25 detachably connected to the connecting ring 24 by bolts. A plurality of legs 26 are fixedly installed at the bottom of the support 25.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they 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.
