Description
Technical Field
The utility model relates to an underwater bottom sediment sampler, in particular to an air bag sealed sampler suitable for sampling undisturbed bottom sediment in a shallow water area.
Background
The method is an important component in the field of environmental management, and aims to find out the layered sedimentation condition of the water bottom sludge and know the time axes of various sludge depositions so as to make effective prevention and radical treatment measures. Most of the existing various undisturbed sludge sampling devices adopt a sampling mode of sealing the upper end and opening the bottom opening, and sludge is easy to leak in the lifting process of a sampler; other undisturbed sediment samplers that adopt a small amount of bottom opening seals mostly have the problem that the structure is complicated, sealed not tight, inconvenient operation. Therefore, an undisturbed sediment sampler with simple structure, convenient operation and reliable sealing is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provides an air bag sealed undisturbed sediment sampler suitable for sampling shallow water areas. The air bag sealed shallow water undisturbed sediment sampler is simple in structure, convenient to use and reliable in sealing.
As a result of intensive studies on the process of sampling underwater sludge, the inventors of the present invention found that a sampling device of a transparent columnar structure in which a sampler is retracted and extended by a connecting rod and an air bag is sealed is an excellent means for solving the above-mentioned problems, and achieved the present invention.
The utility model aims to realize the purpose through the following technical scheme that the air bag sealed shallow water undisturbed sediment sampler is mainly provided with a sampling head, an air bag assembly, an air pipe, a sampling pipe, a top cover and a connecting rod, and is characterized in that: the sampling tube is a transparent tube, the upper end of the sampling tube is connected with the top cover, and the side wall of the top cover is provided with a bypass hole; the air bag assembly is provided with a connecting pipe, an air bag chamber, an air bag and an air inlet joint, when the air bag assembly is not inflated, the air bag is positioned in the air bag chamber, and after the air bag assembly is inflated, the air bag is expanded to block the channel of the connecting pipe; the upper end of the connecting pipe is communicated with the sampling pipe, and the lower end of the connecting pipe is communicated with the sampling head; the air inlet joint is communicated with the air pipe; the connecting rod is connected with the top cover.
The practical use and operation process of the air bag sealed shallow water undisturbed sediment sampler comprises the following steps: the sampling device is pressed into underwater silt by holding the connecting rod, the sampling head can be more easily cut into the bottom silt by rotating the connecting rod, and the silt enters the sampling tube through the air bag assembly connecting tube; inflating the air bag by using an air pump until the air bag completely blocks a connecting pipe channel; and lifting the sampling device out of the water surface by lifting the pull rod to finish sampling. The air bag sealed shallow water undisturbed sediment sampler has no disturbance to sludge in the sampling process, is convenient to keep the undisturbed sediment, and has the advantages of simple structure, convenience in use and reliable sealing.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
in the embodiment, referring to the attached drawings, the air bag sealed shallow water undisturbed sediment sampler is mainly provided with a sampling head 1, an air bag component 2, an air pipe 3, a sampling pipe 4, a top cover 5 and a connecting rod 6; the sampling head 1 is of a stainless steel circumferentially symmetrical knife-shaped structure, and is convenient to cut into bottom mud; the sampling tube 4 is a transparent nylon tube, the upper end of the sampling tube is connected with a stainless steel top cover 5, and the side wall of the top cover 5 is provided with a through bypass hole 5.1; the stainless steel air bag component 2 is provided with a connecting pipe 2.1, an air bag chamber 2.2, an air bag 2.3 and an air inlet joint 2.4, when the stainless steel air bag component is not inflated, the air bag 2.3 is positioned in the air bag chamber 2.2, and after the stainless steel air bag component is inflated, the air bag 2.3 expands to block a channel of the connecting pipe 2.1; the upper end of the connecting pipe 2.1 is communicated with the sampling pipe 4, and the lower end is communicated with the sampling head 1; the air inlet joint 2.4 is communicated with the air pipe 3. When the sampler is actually used, the sampling device is pressed into underwater silt by the hand-held connecting rod 6, the sampling head 1 can be more easily cut into the bottom silt by rotating the connecting rod, and the silt enters the sampling tube 4 through the air bag component connecting tube 2.1; inflating the air bag 2.3 by using an air pump until the air bag completely blocks the channel of the connecting pipe 2.1; and lifting the pull rod 6 upwards to lift the sampler out of the water surface to finish sampling.
While the utility model has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes can be made therein without departing from the spirit and scope thereof.
