Description

Technical Field

[0001] The utility model relates to the technical field of water body sample collection, in particular to a sampling tool used for environmental assessment water ecological investigation. Background Art

[0002] Water ecology refers to the impact of environmental water factors on organisms and the adaptation of organisms to various water conditions. When conducting environmental impact assessment water ecology surveys, sampling tools are usually needed to sample water sources in the water ecological geology and test the water quality to ensure that the water resource environment is not damaged.

[0003] A hydrological and water resource sampling device proposed by searching the publication number CN218725626U is found. The movement of the nut drives the slider to slide on the surface of the guide rod, and the movement of the slider drives the connecting wire to reciprocate between the two fixed plates, so that when the winding shaft reels the connecting wire, the connecting wire can be evenly wound on the surface of the winding shaft, thereby preventing the connecting wire from being entangled in one place and causing knots, and optimizing the convenience of retracting and releasing the connecting wire. However, when sampling water samples at different depths, the sampling tube moves upward after sampling from the deep, and the water in the shallower place will also enter the sampling tube and mix with the sample inside the sampling tube. The sampling tube lacks sealing, which will affect the subsequent detection of water quality. Therefore, a sampling tool for environmental impact assessment water ecological investigation is proposed. Utility Model Content

Through the arrangement of the water outlet pipe 20 and the valve 21, the sample in the water storage chamber 17 can be discharged easily. A first counterweight block 22 is arranged on the bottom surface of the sampling box 11, and a second counterweight block 23 is arranged on the top surface of the vehicle body 1. Through the arrangement of the second counterweight block 23, the weight of the vehicle body 1 is increased to prevent the vehicle body 1 from being more stable during use. Through the arrangement of the first counterweight block 22, the weight of the sampling box 11 can be increased to reduce the shaking of the sampling box 11 during sampling. A push handle 24 is fixedly installed on the top surface of the vehicle body 1, and a locking universal wheel 25 is fixedly installed on the bottom surface of the vehicle body 1. Through the arrangement of the push handle 24 and the locking universal wheel 25, a certain mobility is provided for the device, which is convenient for movement and more convenient to use.

[0020] Specifically, the adjustment component includes a first motor 3 fixedly installed on one side of the fixed frame 2, a first threaded rod 4 is fixedly installed on the output end of the first motor 3, a threaded block 5 is threadedly installed on the surface of the first threaded rod 4, a slide groove 7 is opened inside the fixed frame 2, and the moving rod 6 is slidably connected to the slide groove 7. Through the setting of the adjustment component, the output end of the first motor 3 rotates, driving the first threaded rod 4 to rotate, so that the threaded block 5 moves, and then drives the moving rod 6 to move, so that the moving rod 6 moves out of the slide groove 7 to adjust the position of the sampling box 11.

[0021] Specifically, the lifting component includes a second motor 8 fixedly mounted on the surface of the moving rod 6, a winding roller 9 fixedly mounted on the output end of the second motor 8, and a pull rope 10 is arranged on the surface of the winding roller 9. Through the setting of the lifting component, the output end of the second motor 8 rotates, driving the winding roller 9 to rotate, unwinding the pull rope 10, and then adjusting the height of the sampling box 11, so as to facilitate sampling of water sources at different depths.

[0022] During use: push the push handle 24 to move the vehicle body 1 to the water source to be sampled, start the first motor 3, and rotate the output end of the first motor 3 to drive the first threaded rod 4 to rotate, so that the threaded block 5 moves, and then drive the moving rod 6 to move, so that the moving rod 6 moves out of the slide slot 7, and adjust the position of the sampling box 11 to facilitate sampling in the middle direction of the sampling water source. After adjusting the sampling position, start the second motor 8, and rotate the output end of the second motor 8 to drive the winding roller 9 to rotate, unwind the pull rope 10, and make the sampling box 11 enter underwater. At this time, the sealing block 16 is located at the water inlet 18, which can prevent water at other depths from entering the water storage chamber 17 when the sampling box 11 descends. When the sampling box 11 is adjusted to the depth where sampling is required, start the third motor 13, and rotate the third motor 13. The output end of the third motor 13 rotates, driving the second threaded rod 14 to rotate, so that the lifting plate 15 moves upward, driving the sealing block 16 to move upward, and the water at this depth enters the water storage chamber 17 through the water inlet 18. The setting of the filter plate 19 can prevent impurities in the water from entering the water storage chamber 17 and polluting the sampling box 11. After the sampling is completed, the third motor 13 is started again to drive the second threaded rod 14 to rotate, so that the lifting plate 15 moves downward, and the sealing block 16 is moved to the water inlet 18 to prevent the water inside and outside the sampling box 11 from mixing. The second motor 8 is started again to rotate the winding roller 9 and reel the pull rope 10, so that the sampling box 11 can be pulled out of the water. By opening the valve 21, the sample in the water storage chamber 17 can be discharged from the outlet pipe 20, which is convenient for subsequent detection.
