Description

Technical Field

[0001] The utility model relates to the technical field of bottom mud samplers, in particular to a bottom mud sampler suitable for small water areas. Background Art

[0002] Sediment is loose material that is deposited and accumulated at the bottom of a water body. Its formation process is the result of the combined effects of multiple factors, including suspended particle deposition, biological activity, chemical deposition, surface runoff input, and hydrodynamic processes. Sediment is rich in a large number of pollutants and nutrients. If the sediment is disturbed or damaged, it will have an adverse effect on the health of the aquatic ecosystem.

[0003] Sampling and testing of sediment can help us understand the pollutants present in the sediment, assess the degree of water pollution, determine the potential risks to the water ecology, and develop corresponding remediation methods to clear or reduce pollutants in the sediment to the maximum extent possible.

[0004] At present, columnar samplers that use gravity rings and sampling tubes to enter the water bottom to collect sediments are widely used in deep sea or rapids environments. However, this type of sampler depends on the depth of the water body, and bottom mud sampling may be limited in shallow waters or near the high tide line. It also requires the cooperation of multiple people to operate, has high labor costs, and is not suitable for small, shallow waters. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a bottom sediment sampler suitable for small waters. One person can operate it to perform bottom sediment sampling. The operation is convenient and the labor cost is low.

The telescopic handle can be extended and locked as needed, making it convenient to adjust the length as needed. When sampling sediment, hold the gripping assembly tightly and put the stainless steel collection bucket into the water through the telescopic handle. The stainless steel collection bucket is lifted after scraping the sediment from the bottom of the water. The movable lifting mechanism of the collection bucket allows the stainless steel collection bucket to be movable, making it convenient for the stainless steel collection bucket to be dumped on the bottom of the water for sediment sampling. After lifting, the stainless steel collection bucket remains in a vertical state. The movable quick-release mechanism detachably connects the telescopic handle and the collection bucket handle in the movable lifting mechanism of the collection bucket. When the sediment in the stainless steel collection bucket needs to be poured out, if the telescopic handle affects the dumping work, loosen the butterfly nut to disengage the quick-release stud on the movable sleeve from the fixing ring, remove the telescopic handle, and lift the stainless steel collection bucket by the collection bucket handle alone, so that the sediment collected in the stainless steel collection bucket can be dumped into the collection tank.

[0011] Furthermore, the movable lifting mechanism of the collection bucket includes a fixed round seat, bolts, a connecting ring, an anti-slip nut and a collection bucket handle. The left and right sides of the top of the stainless steel collection bucket are respectively provided with fixed round seats, and two bolts are respectively inserted in the through holes in the middle of the two fixed round seats, and the hexagonal twist heads of the bolts are located inside the stainless steel collection bucket. The collection bucket handle is an inverted U-shaped structure, and the two ends of the bottom of the collection bucket handle are respectively fixedly connected to two connecting rings, and the ends of the two bolts located on the outside of the stainless steel collection bucket respectively pass through the two connecting rings and are threadedly connected with anti-slip nuts. The bolts and anti-slip nuts cooperate to movably install the connecting rings on both sides of the top of the stainless steel collection bucket, so that the collection bucket handle can flexibly move relative to the fixed round seat on the top of the stainless steel collection bucket. The collection bucket handle is convenient for lifting the stainless steel collection bucket, and the top of the stainless steel collection bucket is a semicircular arch structure.

[0012] Furthermore, the grip assembly includes a grip sleeve, a retaining ring, a grip platform and a finger groove. The end of the telescopic handle away from the fixed ring is fixedly sleeved with two grip sleeves. The outer peripheral sides of both ends of each grip sleeve are integrally connected with retaining rings, and the top of each grip sleeve is provided with a grip platform, and the bottom of each grip platform is provided with four finger grooves at equal distances. The grip sleeve and the retaining ring are both made of rubber. The grip sleeve can improve the comfort of holding the end of the telescopic handle.

The grip platform and the finger groove facilitate the user to hold the grip sleeve tightly.

[0013] Furthermore, it also includes a pulling handle. The upper and lower sides of the telescopic handle close to one end of the fixing ring are respectively provided with a pulling handle. The pulling handle is used to facilitate pulling the end of the telescopic handle.

[0014] Furthermore, it also includes scale lines. The outer side and the inner side of the stainless steel collection bucket are respectively provided with scale lines at equal vertical distances. The scale lines can indicate the amount of mud collected by the stainless steel collection bucket.

[0015] Furthermore, it also includes a bottom release mechanism for the bottom mud, which includes a bottom cover and an external threaded sleeve. The bottom of the stainless steel collection barrel is provided with a round opening, and the top of the bottom cover is integrally formed with an external threaded sleeve, and the outer side of the external threaded sleeve is threadedly connected to the inner side of the bottom of the stainless steel collection barrel. The bottom cover is detachably mounted on the stainless steel collection barrel with the help of the external threaded sleeve, and the round opening at the bottom of the stainless steel collection barrel can be opened, so that the bottom mud in the stainless steel collection barrel can be discharged from the bottom round opening conveniently, and the interior of the stainless steel collection barrel can also be cleaned conveniently.

[0016] Furthermore, the bottom mud release mechanism also includes a mud discharge pipe opening, a convex seat, a rotating shaft, an ear seat and a rotating cover. The bottom cover is in a cone shape, and the bottom diameter of the bottom cover is smaller than the top diameter. The center of the bottom cover is provided with a mud discharge pipe opening, one side of the mud discharge pipe opening is fixedly connected with a convex seat, the bottom of the convex seat is rotatably connected to the ear seat through a rotating shaft, and the side of the ear seat is fixedly connected with a rotating cover. The setting of the mud discharge pipe opening can reduce the speed of mud discharge. When mud discharge is required, the rotating cover is rotated relative to the rotating shaft so that the rotating cover cannot block the mud discharge pipe opening. At this time, the bottom mud in the stainless steel collection bucket is discharged through the mud discharge pipe opening. If the rotating cover blocks the mud discharge pipe opening, the discharge of the bottom mud in the stainless steel collection bucket can be prevented.

[0017] Furthermore, the bottom mud release mechanism also includes a screw hole ring 1, a butterfly bolt and a screw hole ring 2. The side of the mud discharge pipe opening away from the convex seat is provided with a screw hole ring 2, and the side of the rotating cover away from the ear seat is provided with a screw hole ring 1, and the inner thread of the screw hole ring 1 is connected with a butterfly bolt. When the rotating cover blocks the mud discharge pipe opening, the butterfly bolt on the screw hole ring 1 is twisted to make the top of the butterfly bolt threadedly connected with the screw hole ring 2, and the position of the rotating cover can be locked. If the rotating cover needs to be rotated, the butterfly bolt is loosened to make the top of the butterfly bolt separate from the screw hole ring 2, and the rapid locking control of the rotating cover can be achieved without the help of work.
