DETAILED DESCRIPTION

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0021] Embodiment: A sampling instrument for field epidemiological investigation, such as Figure 1 and Figure 2 As shown, it includes a protective cover 1, a handle 2, a driving mechanism 3, a sampling rod 4 and a storage mechanism 5. The top of the protective cover 1 is fixed with the handle 2, the protective cover 1 is provided with the driving mechanism 3 and the storage mechanism 5, the storage mechanism 5 is provided with the sampling rod 4, and the sampling rod 4 is provided with a plug hole 41 in the middle of the top.

[0022] like Figure 3 As shown, the driving mechanism 3 includes an electric slide rail 31, an electric slide seat 32, a cylinder 33 and a rubber insert 34. The two electric slide rails 31 are respectively welded to the upper parts of the front and rear side walls in the protective cover 1. The electric slide seat 32 is slidably connected between the two electric slide rails 31. The cylinder 33 is installed in the middle of the bottom of the electric slide seat 32. The rubber insert 34 is fixedly connected to the telescopic rod of the cylinder 33. The rubber insert 34 has a certain elasticity, and the diameter of the rubber insert 34 is slightly larger than the diameter of the insertion hole 41. When the electric slide seat 32 slides along the electric slide rail 31 to the top of the sampling rod 4, the cylinder 33 can drive the rubber insert 34 to move downward and insert into the insertion hole 41, so that the sampling rod 4 can be fixed on the rubber insert 34, so that the electric slide rail 31 and the cylinder 33 can cooperate to drive the sampling rod 4 to move on the surface of the object for sampling.

[0023] like Figure 4 and Figure 5As shown, the storage mechanism 5 includes a storage box 51, a cover plate 52, a hydraulic cylinder 53, an electric push rod 54, a circular plate 55 and a pull rod 56. The storage box 51 is slidably connected to the lower right part of the inner side of the protective cover 1, and the sampling rod 4 is placed in the storage box 51. The top of the storage box 51 is rotatably connected to the cover plate 52. The front and rear sides of the storage box 51 are rotatably connected to the hydraulic cylinder 53. The telescopic rods of the hydraulic cylinder 53 are rotatably connected to the cover plate 52. The front and rear sides of the storage box 51 are connected to the electric push rod 54. The circular plate 55 is connected to the telescopic rod of the electric push rod 54. When the electric push rod 54 drives the circular plates 55 on the front and rear sides to move toward each other, the circular plates 55 can clamp and limit the sampling rod 4, so that the socket 41 on the sampling rod 4 can always remain facing upward, ensuring that the rubber insert 34 can move downward and be accurately inserted into the socket 41. The front side of the storage box 51 is fixedly connected to the pull rod 56.

[0024] When in use, the staff uses the handle 2 to place the protective cover 1 on the surface of the object in the public health area where sampling is required, drives the cover plate 52 to rotate upward and open through the hydraulic cylinder 53, and then drives the electric slide 32 to move to the right through the electric slide rail 31, thereby driving the cylinder 33 and the rubber insert 34 to move to the right to just above the storage box 51, so that the rubber insert 34 is aligned with the socket 41 of the sampling rod 4, and then drives the rubber insert 34 to move downward through the cylinder 33 and insert it into the socket 41 of the sampling rod 4, and then drives the circular plates 55 on the front and rear sides to move away from each other through the electric push rod 54, so that the circular plates 55 release the sampling rod 4, and then drives the rubber insert 34 through the cylinder 33. 4 moves upward, which can drive the sampling rod 4 to move upward and separate from the storage box 51, and then the sampling rod 4 can be driven to move on the surface of the object through the action of the electric slide rail 31 and the cylinder 33, so that the sampling rod 4 can scrape the surface of the object for sampling. After the sampling is completed, the above operation can be repeated to place the sampling rod 4 back into the storage box 51, and then the sampling rod 4 can be separated from the rubber insert 34, and the cover plate 52 can be driven downward to rotate and close by the hydraulic cylinder 53, so that the sampling rod 4 with the sample can be sealed and stored, and the staff can pull the storage box 51 forward to take it out through the pull rod 56, which can effectively prevent the sample from contacting with the external environment and ensure the normal subsequent detection of the sample.

[0025] like Figure 2 As shown, an ultraviolet lamp 6 is also included. The top of the protective cover 1 is connected with the ultraviolet lamp 6. The setting of the ultraviolet lamp 6 can disinfect and sterilize the inside of the protective cover 1 before and after sampling to prevent cross contamination, further ensure the purity of the sample, and ensure the normal progress of subsequent sample testing.

[0026] like Figure 1As shown, a transparent window 7 is also included. The transparent windows 7 are connected to the left and right sides of the protective cover 1. The design of the transparent windows 7 allows the staff to observe the internal sampling operation without opening the protective cover 1, which is convenient for monitoring and recording.

[0027] like Figure 1 As shown, a rubber pad 8 is also included. The bottom of the protective cover 1 is connected to the rubber pad 8. The rubber pad 8 can effectively increase the friction with the ground to prevent the sampler from sliding during operation.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
