[0018] It should be noted first that in different described embodiments, the same components are provided with the same reference numerals or the same component names. Among them, the disclosed content included in the whole specification can be meaningfully applied to the same components with the same reference numerals or the same component names. The positional descriptions selected in the specification, such as up, down, lateral, etc., also refer to the directly described and illustrated drawings and are meaningfully applied to the new positions when the positions change.
[0019] Embodiment: A nuclear radiation detector for facilitating soil sampling and detection, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown in the figure, it includes a soil radon detector 1, a sampling rod 2, an air pipe 3, a fixing ring 4, a bolt 401 and a rotating ring 5. A fixing ring 4 is provided on the rear side wall of the soil radon detector 1. A bolt 401 is movably inserted into the fixing ring 4. A through hole for the bolt 401 to pass through is provided on the circumferential wall of the fixing ring 4. A rotating ring 5 is rotatably arranged inside the fixing ring 4. Circular holes adapted to the bolt 401 are evenly spaced on the outer circumferential wall of the rotating ring 5. When a circular hole on the rotating ring 5 is aligned with the through hole on the fixing ring 4, the bolt 401 is inserted into the fixing ring 4 and the rotating ring 5 from top to bottom to limit the rotating ring 5, thereby fixing the rotating ring 5 on the fixing ring 4. The sampling rod 2 is installed on the rotating ring 5. An air pipe 3 is connected between the soil radon detector 1 and the sampling rod 2. Symmetric handrails 11 are provided on both sides of the top of the soil radon detector 1. The convenient lifting of the soil radon detector 1 is realized through the handrails 11. At the same time, the handrails 11 are designed to facilitate the user to apply appropriate pressure to push the sampling rod 2 deep into the soil for sampling. A filter nozzle 12 for filtering and then discharging the sampled gas is provided on the soil radon detector 1. The harmful gas in the sampled soil is input into the soil radon detector 1 through the sampling rod 2 and the air pipe 3 for detection, and after the detection is completed, it is discharged through the filter nozzle 12 after being filtered and purified.
[0020] As Figure 2 shown, it further includes a positioning rod 10 and a sliding sleeve 1001. A sliding sleeve 1001 parallel to the sampling rod 2 is provided on the outer circumferential wall of the rotating ring 5. A positioning rod 10 is slidably connected inside the sliding sleeve 1001. During the sampling operation, the sampling point is first determined by using the positioning rod 10, and then the sampling rod 2 is accurately inserted into this area for sampling.
[0021] When in use, pull out the bolt 401 to release the position limit of the rotating ring 5 and allow it to rotate freely. Then, drive the rotating ring 5 to rotate counterclockwise by 90 degrees through the sampling rod 2 to Figure 6 the state shown in the figure. Then, after the circular hole on the rotating ring 5 is aligned with the through hole on the fixing ring 4, insert the bolt 401 into the fixing ring 4 and the rotating ring 5 from top to bottom, thereby fixing the rotating ring 5 inside the fixing ring 4, so that the sampling rod 2 maintains Figure 6 the state shown in the figure; Subsequently, position to the sampling location through the positioning rod 10, then hold the handrail 11 and gently press down to guide the sampling rod 2 to smoothly insert into the soil to ensure effective sampling, and the sampled soil is detected by the soil radon detector 1.
[0022] As Figure 2 and Figure 4 shown, it further includes a cross bar 6, a sleeve 7, a rubber sleeve 701 and a tension spring 8. A cross bar 6 is connected to the circumferential side wall of the fixing ring 4. A sleeve 7 is slidably connected to the cross bar 6. A tension spring 8 is provided between one end of the cross bar 6 far from the fixing ring 4 and the end of the inner cavity of the sleeve 7. Figure 4The shown tension spring 8 is a three-dimensional view in a deformed state. A rubber sleeve 701 for limiting the sampling rod 2 is provided on an outer wall of the sleeve 7 near the sampling rod 2. In the initial state, the sleeve 7 and the rubber sleeve 701 are close to the fixing ring 4. When it is necessary to fix the sampling rod 2, the sleeve 7 and the rubber sleeve 701 are pulled in a direction away from the fixing ring 4, causing the tension spring 8 to deform. Subsequently, the sampling head of the sampling rod 2 is clamped by the rubber sleeve 701 to fix the sampling rod 2 in this way.
[0023] When the sleeve 7 is released, the sleeve 7 will slide back towards the fixing ring 4 under the elastic force of the tension spring 8, together with the rubber sleeve 701, and approach the sampling rod 2.
[0024] As Figure 1 and Figure 5 As shown, a magnetic block 901 is provided on the outer wall of the opening side of the rotating ring 5. A cleaning ring 9 for cleaning the outer wall of the sampling rod 2 is slidably connected to the sampling rod 2. The cleaning ring 9 is magnetically attracted and cooperated with the magnetic block 901, and the cleaning ring 9 is limited to the rotating ring 5 through the magnetic attraction and cooperation between the cleaning ring 9 and the magnetic block 901.
[0025] After sampling is completed, the cleaning ring 9 is pulled axially outwards along the sampling rod 2, and the cleaning purpose is achieved through its frictional action with the surface of the sampling rod 2.
[0026] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
