Description

Technical Field

[0001] This utility model relates to the field of sampler technology, specifically a hydrogeological exploration sampler. Background Technology

[0002] Hydrogeological exploration, also known as hydrogeological survey, refers to a comprehensive and systematic hydrogeological investigation and research work carried out to ascertain the hydrogeological conditions of a region.

[0003] When sampling surface water in certain areas, water quality samplers are usually used. Currently available simple water quality samplers generally have a large, rotatable measuring cup or cylinder attached to a telescopic rod. In use, the telescopic rod is operated to extend it downwards into the liquid surface, so that the measuring cup is below the liquid surface, thereby realizing the surface water sampling operation. This simple sampler has the advantages of being simple, fast, and convenient for sampling.

[0004] However, this simple sampler has obvious defects in actual use. Since most of the measuring cups are not equipped with lids, they are contaminated by floating garbage, duckweed and other impurities during the sampling process, which leads to sample contamination and deviation in measurement results.

[0005] In view of this, this application proposes a hydrogeological exploration sampler, which aims to solve the above-mentioned problems of existing simple water quality samplers. Utility Model Content

[0006] To solve the above-mentioned technical problems, this application provides a hydrogeological exploration sampler, including a telescopic rod, a bracket fixedly connected to the front end of the telescopic rod, a sampling bucket rotatably connected inside the bracket, and a bucket lid, the bucket lid being threadedly connected inside the sampling bucket, and a closing component being movably installed on the bucket lid;

[0007] The closing assembly includes a cover plate, a bearing, a movable frame, a V-shaped spring, and a pull rope. The movable frame is rotatably mounted to the bucket lid via the bearing. The cover plate is fixedly connected to one side of the movable frame, and the V-shaped spring is fixedly connected to the other side of the movable frame. The pull rope passes through the movable frame.

[0008] The bucket lid is provided with a water inlet hole, and the cover plate is located above the water inlet hole.

[0009] In some embodiments, a threaded groove is provided at the upper part of the sampling bucket, and a connecting thread is provided at the side of the bucket cover, the connecting thread being movably installed in the threaded groove.

[0010] In some embodiments, the closure assembly further includes a sealing gasket and a rotating rod. The sealing gasket is fixedly connected to the bottom surface of the cover plate and is located above the water inlet. The rotating rod is fixedly connected to the movable frame and is rotatably connected to the cover plate via a bearing.

[0011] In some embodiments, the closure assembly further includes a positioning rod and a mounting plate, the positioning rod and the mounting plate being fixedly connected to the cover plate, the other side of the movable frame being located between the positioning rod and the mounting plate, and the two sides of the V-shaped spring being fixedly connected to the movable frame and the mounting plate respectively by welding.

[0012] In some embodiments, the closure assembly further includes a movable hole and a positioning ball. The movable hole is formed on the movable frame, the pull rope is movably installed in the movable hole, and the positioning ball is fixedly connected to one end of the pull rope and is located on the side of the movable frame.

[0013] In some embodiments, the closure assembly further includes a first coil and a second coil, the first coil being fixedly connected to the cover plate, the second coil being distributed on the telescopic rod, and the second coil being welded to the joint positions on the telescopic rod, the pull rope passing through the first coil and the second coil in sequence.

[0014] In some embodiments, the closure assembly further includes a pull ring, which is fixedly connected to the other end of the pull cord.

[0015] This utility model has at least the following beneficial effects:

[0016] By operating the closing mechanism and pulling the ring, the positioning ball pushes the movable frame to rotate, causing the cover plate on the side of the movable frame to move and open the water inlet, allowing external surface water to enter easily. After the water inlet is finished, the pull rope is released, and the V-shaped spring returns to its original position, pushing the movable frame in the opposite direction. This causes the cover plate and sealing gasket to reseal the water inlet, preventing external surface water from continuing to enter. This also makes it difficult for garbage, duckweed, and other impurities on the river surface to enter during the water discharge process of the sampling bucket, thus preventing sample contamination and making the test results more accurate.

[0017] The lid is connected to the sampling cylinder via a threaded groove, making the lid easy to remove, reducing dead corners, and facilitating more thorough cleaning of the sampling cylinder. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a hydrogeological exploration sampler, including a telescopic rod 1, a bracket 2 fixedly connected to the front end of the telescopic rod 1, a sampling bucket 3 rotatably connected inside the bracket 2, and a bucket cover 4, the bucket cover 4 being threadedly connected inside the sampling bucket 3, a threaded groove 301 being provided at the upper part of the sampling bucket 3, a connecting thread 401 being provided at the side of the bucket cover 4, the connecting thread 401 being movably installed in the threaded groove 301, and a closing component 5 being movably installed on the bucket cover 4;

[0028] The lid 4 is connected to the threaded groove 301 of the sampling bucket 3 via the connecting thread 401, so that the lid 4 can be completely removed from the sampling bucket 3. This avoids the lid 4 creating dead corners inside the sampling bucket 3 during cleaning, allowing the sampling bucket 3 to be cleaned more thoroughly.

[0029] The closing assembly 5 includes a cover plate 501, a bearing 505, a movable frame 503, a V-shaped spring 507, and a pull rope 512. The movable frame 503 is rotatably installed with the bucket lid 4 via the bearing 505. The cover plate 501 is fixedly connected to one side of the movable frame 503, and the V-shaped spring 507 is fixedly connected to the other side of the movable frame 503.

[0030] Furthermore, the bucket lid 4 is provided with a water inlet hole 402, and the cover plate 501 is located above the water inlet hole 402. The closing assembly 5 also includes a sealing gasket 502 and a rotating rod 504. The sealing gasket 502 is fixedly connected to the bottom surface of the cover plate 501 and is located above the water inlet hole 402. The rotating rod 504 is fixedly connected to the movable frame 503 and is rotatably connected to the cover plate 501 through a bearing 505.

[0031] The sealing gasket 502 is fixedly connected to the bottom surface of the cover plate 501 and seals the water inlet hole 402, thereby enabling the cover plate 501 to seal the water inlet hole 402. The sealing gasket 502 is slidably connected to the surface of the cover plate 501, making it easy to remove the sealing gasket 502 from the water inlet hole 402.

[0032] Furthermore, the closing assembly 5 also includes a positioning rod 506 and a mounting plate 508. The positioning rod 506 and the mounting plate 508 are fixedly connected to the cover plate 501. The other side of the movable frame 503 is located between the positioning rod 506 and the mounting plate 508. The two sides of the V-shaped spring piece 507 are fixedly connected to the movable frame 503 and the mounting plate 508 respectively by welding.

[0033] Mounting plate 508 fixes one end of V-shaped spring 507 and provides support for V-shaped spring 507. The rotation of movable frame 503 will cause V-shaped spring 507 to fold. Positioning rod 506 stops the movement of movable frame 503, so that the stop position of movable frame 503 is such that cover plate 501 is located on water inlet hole 402.

[0034] When the movable frame 503 is pulled to the side by an external force, the rotating rod 504 on the movable frame 503 rotates through the bearing 505, the V-shaped spring 507 is folded, and the cover plate 501 on the movable frame 503 moves out of position simultaneously, so that the water inlet 402 is opened to facilitate the entry of external surface water. After the water inlet is finished, the movable frame 503 is released, the V-shaped spring 507 returns to its original position, and pushes the movable frame 503 to rotate in the opposite direction. The movable frame 503 stops rotating when it encounters the positioning rod 506. At this time, the cover plate 501 and the sealing gasket 502 below the cover plate 501 are located above the water inlet 402, thereby closing the water inlet 402 again to prevent external surface water from entering and causing sample contamination.

[0035] Example 2:

[0036] Please see Figure 1 , Figure 3 , Figures 5 to 6 Based on Embodiment 1, this utility model provides another technical solution: the pull rope 512 passes through the movable frame 503, and the closing component 5 also includes a movable hole 509 and a positioning ball 513. The movable hole 509 is opened on the movable frame 503, the pull rope 512 is movably installed in the movable hole 509, and the positioning ball 513 is fixedly connected to one end of the pull rope 512, and the positioning ball 513 is located on the side of the movable frame 503.

[0037] Furthermore, the closing assembly 5 also includes a first coil 510 and a second coil 511. The first coil 510 is fixedly connected to the cover plate 501, and the second coil 511 is distributed on the telescopic rod 1. The second coil 511 is welded to the joint position on the telescopic rod 1. The pull rope 512 passes through the first coil 510 and the second coil 511 in sequence. The closing assembly 5 also includes a pull ring 514, which is fixedly connected to the other end of the pull rope 512.

[0038] The pull rope 512 is guided upward along the telescopic rod 1 by coil 510 and coil 511. The pull ring 514 is placed above the telescopic rod 1, so that when the staff holds the telescopic rod 1, they can operate the pull ring 514 to pull the pull rope 512 to move. This causes the positioning ball 513 at the lower end of the pull rope 512 to move synchronously. The positioning ball 513 pushes the movable frame 503 to rotate, thereby providing power for the movement of the cover plate 501.
