Description

Technical Field

[0001] This utility model relates to the field of hydrological and water resources exploration technology, specifically a hydrological and water resources sample storage device. Background Technology

[0002] Hydrological and water resources engineering focuses on water resources, systematically studying their distribution, formation, and evolution. It also involves collecting and processing water resources information and planning and developing water resources. Hydrological and water resources engineering is an important professional field in water conservancy and also belongs to the environmental protection industry. During the hydrological and water resources survey process, it is necessary to sample water bodies. The samples are generally stored in sample tubes. Due to the different types of water bodies, there are many types of water samples, so the storage device needs to accommodate a large number of sample tubes at the same time and classify them.

[0003] In the prior art, for example, Chinese Patent Publication No. CN218288623U discloses a water sample storage device for hydrogeological exploration. First, the anti-collision buffer foam is taken out and separated on both sides. Then, the water sample storage bottle is inserted into the sample bottle slot. Next, the two sets of anti-collision buffer foam are fastened together to fix the water sample storage bottle inside the anti-collision buffer foam. Then, the anti-collision buffer foam is inserted into the limiting groove. Then, the fixing plate is placed on the anti-collision buffer foam and the water sample storage bottle passes through the fixing plate. Finally, the limiting buckle is rotated to fix the fixing plate, so that the fixing plate fixes the anti-collision buffer foam and the water sample storage bottle, preventing the water sample storage bottle from being damaged by collision and also preventing the water sample storage bottle from tilting. Samples from the same water body or of the same type generally need to be tested multiple times and the data compared to obtain more accurate test results. This requires taking multiple water sample storage bottles at once. However, in the above technical solution, the water sample storage bottles can only be taken one by one, which is quite laborious. Moreover, if the operation is not done properly when opening the anti-collision buffer foam, the water sample storage bottle may fall out of the sample bottle slot and break, resulting in sample loss.

[0075] When the pressing and pushing mechanism 4 is rotated, the indicator 6 serves as a prompt, allowing staff to clearly know whether the top block 48 is aligned with the push block 75 in the multi-layer sample storage mechanism. This enables staff to quickly remove the storage box 8 from the multi-layer sample storage mechanism, improving the efficiency of sample testing.

[0076] like Figure 7 , Figure 8 and 9 As shown, the storage box 8 includes an outer box 81 and an inner box 85;

[0092] Using this invention, when retrieving the storage box 8, the worker first observes the classification labels on the top surfaces of multiple top plates 71 through the observation window 2. After finding the required classification label, the worker rotates the pressing and pushing mechanism 4 to align the pointer 6 with the observation window 2 corresponding to the classification label. Then, the corresponding box door 3 is opened, and the pressing column 42 is pressed down. The pressing column 42 drives the limiting plate 44 to move downward, which in turn drives the two racks 45 to move downward. The racks 45 drive the column gear 46 to rotate clockwise, and the main gear drives... The second moving rack 47 moves outward from the rotating column 43, pushing the top block 48 outward from the receiving groove 431. The top block 48 enters the side hole 92, pushing the push block 75 outward from the side hole 92. The push block 75 pushes the storage rack 7 outward from the fixing groove 91. The operator removes the multi-layer sample storage mechanism through the door hole 11. Then, the operator pulls the storage box 8 out of the receiving space of the storage rack 7 through the pull groove 813. During the process of pulling out the storage box 8, the locking block 861 is guided by the locking groove 77. Moving upwards, the slide plate 86 slides upwards along the inner wall of the support cylinder 83, compressing the spring 84. After the storage box 8 is removed, the spring 84 returns to its original position, and the slide plate 86 resets. Then, the sealing cover 82 is removed, and the water sample in the inner box 85 is tested. After the sample test is completed, the storage box 8 is pushed into the receiving space of the storage rack 7. During the process of pushing into the receiving space, the locking block 861 is guided by the inner slope of the guide groove 76, and the locking block 861 moves upwards. The slide plate 86 slides upwards along the inner wall of the support cylinder 83, and the spring 84 is compressed. 4. After compression again, the locking block 861 is re-engaged into the slot 77, the spring 84 returns to its original position, and the sliding plate 86 pushes the locking block 861 downward, so that the locking block 861 is embedded in the slot 77, fixing the storage box 8. Then, the storage rack 7 is pushed back into the fixing slot 91, and the reverse push block 75 is re-embedded into the side hole 92. At the same time, the reverse push block 75 pushes the top block 48 back into the receiving slot 431, the rack 2 47 is pushed back, the column gear 46 rotates in the opposite direction, and drives the two racks 1 45 to move upward. The two racks 1 45 lift the pressing column 42.
