[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3As shown, an anti-pollution activity measurement sampler includes a measuring cup body 1 and a sealing assembly 3. A cup opening 2 is opened at the middle end of the top of the measuring cup body 1. The sealing assembly 3 is arranged on the top of the measuring cup body 1, and the sealing assembly 3 includes a transmission shaft 301, a gear 302, a toothed sealing plate 303, a reset spring 304 and a fixing rod 305. The outer sleeve of the transmission shaft 301 is provided with a gear 302, and the outer side of the gear 302 is connected to the toothed sealing plate 303. The opening on the surface of the toothed sealing plate 303 is provided with a reset spring. 304, and the end of the reset spring 304 is connected to a fixed rod 305, a cup cover 4 is arranged on the outside of the sealing assembly 3, and a protrusion 5 is fixed on the inner surface of the cup cover 4, the sealing assembly 3 is provided with four groups, the transmission shaft 301 and the measuring cup body 1 are rotatably connected, the fixed rod 305 and the measuring cup body 1 are fixedly connected, and the fixed rod 305 is elastically connected to the toothed sealing plate 303 through the reset spring 304, the gears 302 are distributed in an annular manner and equidistantly along the inner side of the cup cover 4, and the cup cover 4 is meshed and connected with the gear 302 through the protrusion 5.

[0022] The specific operation is as follows: the elastic force provided by the reset spring 304 drives the toothed sealing plate 303 to move along the outside of the fixed rod 305 until the toothed sealing plate 303 closes to seal the cup mouth 2, thereby preventing residual medicine from spilling when the measuring cup body 1 is accidentally overturned, isolating the residual medicine and ensuring the personal safety of the staff.

[0023] like Figure 1 and Figure 2 As shown, the outer surface of the cup cover 4 is provided with an anti-slip pad 6, and a cup mouth 7 is opened in the middle of the cup cover 4, the outer surface of the measuring cup body 1 is provided with a grid hole 8, and a carrying rod 9 is provided at the top of the rear end of the measuring cup body 1, and a mounting handle 10 is provided between the upper sides of the measuring cup body 1, and the outer diameter of the measuring cup body 1 is the same as the outer diameter of the cup cover 4.

[0024] The specific operation is as follows: the outer surface of the cup cover 4 is provided with an anti-slip pad 6 to increase friction and prevent slipping when rubbing the cup cover 4. The grid holes 8 distributed in an annular manner below the outer surface of the measuring cup body 1 can enable the radiation source to fully utilize its penetrating characteristics to measure the object to be measured, thereby improving the accuracy of the measurement.

[0025] In summary, when the anti-pollution activity measurement sampler is used, the cup cover 4 is first screwed, and the convex block 5 on the inner surface of the cup cover 4 drives the four gears 302 to drive so that the four transmission shafts 301 rotate simultaneously, and the four gears 302 each drive a toothed sealing plate 303 to drive until the toothed sealing plate 303 is unfolded to expose the cup mouth 1 2, so that the object to be measured can be placed into the measuring cup body 1 through the cup mouth 2 7 and the cup mouth 1 2;

[0026] After the object is placed, the elastic force provided by the reset spring 304 drives the toothed sealing plate 303 to move along the outside of the fixed rod 305 until the toothed sealing plate 303 closes to seal the cup mouth 2. The active sealing function is set to prevent the residual medicine from spilling from the cup mouth 2 when the measuring cup body 1 made of plastic is accidentally overturned during the transfer process, thereby avoiding the pollution of the measuring environment and ensuring the personal safety of the staff;

[0027] Then hold the hand pole 9 and put the measuring cup 1 into the activity meter well for measurement. Since the grid holes 8 are distributed in an annular shape below the outer surface of the measuring cup 1, the penetrating characteristics of the grid holes can be used to enable the ray source to measure the object to be measured, thereby improving the accuracy of the measurement.
