DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0017] like Figures 1 to 5 As shown, a radioactive water environment monitoring device for coal-uranium resource overlapping areas provided by the present invention comprises a plurality of pre-buried casings 1 and a remote control trolley 2. The number of the pre-buried casings 1 is set according to the size of the monitoring area. The pre-buried casings 1 are drilled into the soil of the monitoring area (preferably at a position where seepage or water flows through the surface) by the method of the prior art. The upper end of the pre-buried casing 1 is exposed to the ground. The soil in the pre-buried casing 1 is removed by a hole-cleaning drill bit. Groundwater is stored in the lower end of the pre-buried casing 1. One side of the remote control trolley 2 is fixedly connected to a vertical plate 2. 1. One side of the vertical plate 21 is slidably connected to the support plate 22. The vertical plate 21 is provided with a lifting device 23. The lifting device 23 is a motor screw mechanism, a cylinder slider mechanism or an oil cylinder slider mechanism. The lifting device 23 drives the support plate 22 to rise and fall. The support plate 22 is provided with an extraction device 3. The extraction device 3 at least includes a suspension rod 31. The suspension rod 31 is installed at the bottom of the support plate 22. The lower end of the suspension rod 31 is provided with a first extraction cylinder 32. The upper end of the suspension rod 31 is rotatably connected to the side rod 33. The end of the side rod 33 is fixedly connected to the second extraction cylinder 34. The first radioactivity detector 4 and the second radioactivity detector 5 are fixedly connected to the side of the vertical plate 21. The first radioactivity detector 4 and the second radioactivity detector 5 adopt conventional detectors in the prior art. The first radioactivity detector 4 is arranged corresponding to the first extraction tube 32, and the second radioactivity detector 5 is arranged corresponding to the second extraction tube 34.

[0018] The present invention pre-buries a plurality of pre-buried casings 1 at intervals in the overlapping area of ​​coal and uranium resources where radioactivity needs to be monitored. The inside of each pre-buried casing 1 is cleaned and the upper end is exposed to the ground. When it is necessary to regularly monitor the radioactive water environment, the remote control trolley 2 is operated to reach the position of the pre-buried casing 1, and the lifting device 23 puts the suspension rod 31 of the extraction device 3 into the pre-buried casing 1. The groundwater or silt in the pre-buried casing 1 is extracted through the first extraction tube 32, and the surface or shallow silt, water flow or seepage is extracted through the second extraction tube 34. After the extraction device 3 extracts the sample, the remote control trolley 2 is moved to an area convenient for cleaning radioactive pollutants, the first extraction tube 32 is lifted to the height of the first radioactivity detector 4 and the second extraction tube 34 is located at the height of the second radioactivity detector 5, the samples in the first extraction tube 32 and the second extraction tube 34 are pushed out, the first radioactivity detector 4 and the second radioactivity detector 5 perform radioactivity detection on the extruded or discharged products, thereby respectively monitoring the radioactivity changes in groundwater and the radioactivity changes in the surface environment, and being able to compare the impact of the radioactivity of the groundwater environment on the surface environment, so as to facilitate early warning. Example 2

[0019] like Figures 1 to 5 As shown, the suspension rod 31 is a hollow rod structure, the first extraction cylinder 32 is slidably connected to the first piston plate 35, the upper side of the first piston plate 35 is fixedly connected to the pull rod 36, the upper end of the pull rod 36 is fixedly connected to the cross bar 37, one side of the vertical plate 21 is fixedly connected to the support rod 371, the support rod 371 is arranged corresponding to the cross bar 37, the suspension rod 31 is provided with a through groove 38, the cross bar 37 extends from the through groove 38 to the outside of the suspension rod 31, the bottom of one end of the cross bar 37 is fixedly connected to the electric push rod 39, the lower end of the electric push rod 39 is provided with a contact sensor, and the electric push rod 39 is provided with a contact sensor. The lower end of 39 can contact the upper end of the embedded sleeve 1, and the other end of the cross bar 37 is fixedly connected to the arc guide rail 341. The second extraction cylinder 34 is slidably connected to the second piston plate 342 inside, and the upper side of the second piston plate 342 is fixedly connected to the piston rod 343. A guide groove 344 is set on the side of the piston rod 343. The guide groove 344 is slidably connected to the arc guide rail 341. The arc guide rail 341 allows the second extraction cylinder 34 to be in the rotation position, and the cross bar 37 can also drive the second piston plate 342 to slide through the piston rod 343.

[0020] When this embodiment is working, the suspension rod 31 is lowered by the lifting device 23. After the lower end of the first extraction tube 32 is immersed in the groundwater, the second extraction tube 34 contacts the ground surface. The electric push rod 39 at one end of the cross bar 37 contacts the upper end of the embedded casing 1 and is sensed by the contact sensor. The cross bar 37, the pull rod 36, the piston rod 343 and the second piston plate 342 are stationary relative to the embedded casing 1. At this time, the electric push rod 39 is lifted to make the cross bar 37, the pull rod 36, the piston rod 343 and the second piston plate 342 rise relative to the embedded casing 1, which plays a role in sucking the sample into the first extraction tube 32 and the second extraction tube 34. Finally, the cross bar 37 reaches the upper end of the through groove 38 to extract the sample. Work, then the boom 31 rises through the lifting device 23 and the electric push rod 39 retracts and resets, when the cross bar 37 is further raised with the boom 31, the cross bar 37 is blocked by the support rod 371 and slides relative to the boom 31 toward the lower end of the through groove 38, the first piston plate 35 pushes out the sample in the first extraction cylinder 32, and the second piston plate 342 pushes out the sample in the second extraction cylinder 34, the first radioactivity detector 4 and the second radioactivity detector 5 perform radioactivity detection on the extruded or discharged products, monitor the changes in groundwater radioactivity and surface environment radioactivity at the same position respectively, and can compare the impact of groundwater environment radioactivity on the surface environment, so as to facilitate early warning.

[0021] The side of the suspension rod 31 is rotated relative to the embedded casing 1 at the surface sampling position with the side rod 33 and the second extraction tube 34 through existing technology (such as a motor). When the seepage position is uncertain, water and silt samples at different positions on the surface of the embedded casing 1 can be obtained or soil can be shoveled in, thereby expanding the monitoring range of the surface, thereby making it easier to obtain the impact of underground radioactive contamination on the surface. Example 3

[0022] like Figure 3 to Figure 4 As shown, a slope surface 6 is provided at the bottom of the second extraction cylinder 34, and a suction hole 61 is provided on the slope surface 6. The slope surface 6 is provided corresponding to the rotation direction of the second extraction cylinder 34. If the bottom of the second extraction cylinder 34 contacts the surface silt, the slope surface 6 facilitates the silt to enter the second extraction cylinder 34 through suction. Example 4

[0023] like Figures 1 to 5 As shown, an annular groove 311 is provided on the outer side of the suspension rod 31, a circular ring 312 is spirally slidably connected in the annular groove 311 and a reset torsion spring 313 is provided, the side rod 33 is fixedly connected to the side of the circular ring 312, a spiral groove 314 is provided at the bottom of the annular groove 311, the inner wall of the circular ring 312 is rotatably connected to the ball 315, the ball 315 is limitedly slid in the spiral groove 314, the suspension rod 31 is rotatably connected to the circular ring 7, the circular ring 7 and the circular ring 312 are fixedly connected with a support spring 71, a plurality of arc-shaped rubber blocks 72 are fixedly connected at intervals on the upper end of the embedded sleeve 1, and the arc-shaped rubber blocks 72 are provided corresponding to the side rod 33.

[0024] Regarding the conventional structure in Example 2 that drives the second extraction cylinder 34 to rotate, since the sludge has low water content and high viscosity and the suction hole 61 is located at the bottom of the second extraction cylinder 34, suction difficulties may occur.

[0025] In order to solve the problem that the conventional rotary drive device cannot overcome, a special structure is disclosed in this embodiment to facilitate the smooth suction of the sample into the second extraction cylinder 34. The specific operation is as follows: On the basis of Example 2, after the suspension rod 31 is lowered to the point where the electric push rod 39 just contacts the upper end of the embedded sleeve 1, as the suspension rod 31 further descends, the side rod 33 stops descending after being blocked by the upper end of the embedded sleeve 1, and the suspension rod 31 can continue to descend. Due to the action of the ball 315, the circular ring 7 and the spiral groove 314, the circular ring 7 can bring the side rod 33 to rotate relative to the suspension rod 31 at the upper end of the embedded sleeve 1, thereby realizing that the side rod 33 brings the second extraction tube 34 to rotate and change position (and the reset torsion spring 313 is twisted and stored, and plays a reset role after leaving the upper end of the embedded sleeve 1), which is convenient for adsorbing samples at different positions.

[0026] In order to solve the problem of difficulty in absorbing viscous samples, a number of arc-shaped rubber blocks 72 are fixedly connected at intervals at the upper end of the embedded sleeve 1. The rotation of the side rod 33 through the arc-shaped rubber block 72 will form an effect of lifting the second extraction cylinder 34 upward (the support spring 71 plays a reset role), so that if the lower end of the second extraction cylinder 34 is immersed in the sludge, the rising of the second extraction cylinder 34 facilitates the entry of air into the lower end of the second extraction cylinder 34, thereby facilitating the mixing of sludge with flowing air, and thus facilitating the inhalation of the second extraction cylinder 34. Samples can be smoothly extracted when there is surface water flow or surface sludge.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
