Description

Technical Field

[0001] This utility model relates to the field of downhole sampling technology, specifically a downhole water sample collection device. Background Technology

[0002] "Underground sampling" refers to the technical process of purposefully and systematically collecting samples of solid (such as ore, rock, coal), liquid (such as groundwater, mine water), or gas (such as methane, harmful gases) in underground environments such as mines, tunnels, boreholes, or underground engineering projects.

[0003] Regarding the above and existing related technologies: When conducting downhole sampling operations, it is often necessary to sample water bodies. When collecting water samples, a special sampler is required. Since most samplers lack the ability to collect samples from water bodies at different depths, this can easily lead to problems such as high repetitiveness of operations, which affects the sampling efficiency. Therefore, a downhole water sampling device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

Multiple box covers are located directly above the collection boxes. A pull strip is fixedly connected to the upper surface of the box cover. A locking block is fixedly connected to the bottom end of the box cover. The locking block is inserted into the inner surface of the collection box. Pulling the pull strip causes the pull strip to move the box cover and the locking block, and water flows into the collection box. Pushing the pull strip again causes the pull strip to move the box cover and the locking block, and the locking block is inserted into the inner surface of the collection box. By setting up the collection box, box cover, pull strip and locking block, water samples can be collected conveniently.

[0006] Preferably, a plurality of limiting rings are fixedly connected to the surface of the movable rod, and the inner wall of the limiting ring is slidably connected to the surface of the pull bar. When the pull bar moves, the pull bar slides on the inner surface of the limiting ring, and the limiting ring can restrict the position of the pull bar.

[0007] Preferably, a limiting block is fixedly connected to the surface of the lid, and the surface of the limiting block is slidably connected to the inner wall of the fixing seat. The limiting block slides on the inner wall of the fixing seat, and the limiting block can restrict the position of the lid.

[0008] Preferably, the surface of the fixed base is provided with multiple limiting grooves, and the inner wall of the limiting groove of the fixed base is slidably connected to the surface of the limiting block. When the limiting block moves, the limiting block slides on the inner wall of the limiting groove. The opening of the limiting groove can facilitate the movement of the limiting block.

[0009] Preferably, the bottom end of the fixing base is fixedly connected to multiple storage blocks, the collection box is inserted into the inner surface of the storage blocks, and the inner walls of the storage blocks and the collection box are threadedly connected with positioning pins. By rotating the positioning pins to the inner walls of the storage blocks and the collection box, the position of the collection box can be fixed by setting the storage blocks and positioning pins.

[0010] Preferably, a through groove is provided on the surface of the fixing base near the storage block, and the collection box is inserted into the inner surface of the through groove of the fixing base. When the collection box moves, the collection box passes through the through groove, and the opening of the through groove can store the collection box.

[0011] Preferably, the vertical cross-section of the storage block forms a U-shaped structure. By setting the storage block into a special structure, it is convenient to store the collection box.

[0012] Preferably, the bottom end of the fixing base is provided with a sealing device, the sealing device including a baffle, the baffle is sleeved on the surface of the fixing base, the bottom end of the fixing base is fixedly connected to a storage cylinder, the inner surface of the baffle is fixedly connected to a threaded post, the surface of the threaded post is threadedly connected to the inner wall of the storage cylinder, after the collection box is fixed, the baffle is rotated to drive the threaded post to rotate, the threaded post rotates to the inner surface of the storage cylinder, by setting the baffle, the storage cylinder and the threaded post, the wear of other parts can be reduced.

[0013] Preferably, a sealing ring is fixedly connected to the inner surface of the baffle, and the sealing ring is sleeved on the surface of the fixing seat. The sealing ring can reduce the entry of moisture into the baffle and also reduce wear between the baffle and the fixing seat.

[0015] The advantages of this utility model are: 1. When water samples need to be collected, this utility model involves pushing the collection box through the fixed base, inserting the collection box into the inner surface of the storage block, rotating the positioning pin to the inner wall of the storage block and the collection box, and then pushing the moving rod to move the fixed base, which in turn moves the collection box, allowing it to penetrate deeper into the water. After reaching a certain depth, pulling the pull bar allows it to slide on the inner surface of the limiting ring, causing the box cover to move. The box cover then moves the locking block. Once the box cover is in the appropriate position, water enters the inner surface of the collection box. The movement of the box cover causes the limiting block to slide, which then slides on the inner wall of the limiting groove. After collection is complete, pushing the pull bar moves the box cover and locking block. The depth of the moving rod is then adjusted, and another pull bar is pulled. This device facilitates water sample collection at different depths, reducing repetitive work and increasing sampling efficiency.

[0016] 2. After the collection box is installed, the baffle is rotated to make the threaded column rotate. The threaded column rotates to the inner surface of the collection cylinder. When the baffle moves, it will drive the sealing ring to move. The sealing ring will press against the surface of the fixed seat. When the fixed seat falls, the baffle will push away other objects. By setting the whole device, the contact between the fixed seat and other parts and other objects can be reduced. At the same time, the possibility of the positioning pin coming into contact with water can also be reduced. Attached Figure Description
