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 deepwater 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 in deepwater. The air bag sealed deepwater 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 sampling device is retracted and extended by a pulling rope 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 an air bag sealed deepwater undisturbed sediment sampler is mainly provided with a base, an air bag assembly, an air pipe, a sampling pipe, a top cover, a hanging ring and a traction rope, 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 base; the air inlet joint is communicated with the air pipe; the hanging ring is arranged at the upper end of the top cover; the hauling rope is connected to the hoisting ring.
Further, sealed deep water original state bed mud sampler of gasbag contains the balancing weight.
The practical use and operation process of the air bag sealed deepwater undisturbed sediment sampler comprises the following steps: the sampler is hung on the fixed support by the traction rope, the traction rope is gradually lowered, the sampler is pressed into the mud layer by the balancing weight, the sampling tube is kept in a vertical state by the base, and the mud 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 traction rope upwards to lift the sampler out of the water surface to finish sampling. The air bag sealed deepwater undisturbed bottom sediment sampler has no disturbance to sludge in the sampling process, is convenient to keep the undisturbed state of the bottom sediment, and has the advantages of simple structure, convenience in use and reliable sealing.
