Technical Field

The utility model relates to the field of water sample collection, in particular to a device for sampling petroleum samples in water.

Background

Petroleum is a complex mixture of many hydrocarbons of different molecular weight and structure, and organic compounds containing small amounts of sulfur, nitrogen and oxygen. Wherein the hydrocarbon content accounts for 96 to 99 percent and is mainly composed of alkane, cyclane and aromatic hydrocarbon. Petroleum in water mainly exists in the forms of non-dissolved oil, emulsified oil and dissolved oil, and the distribution uniformity in a water body is relatively poor. According to the requirements of relevant technical specifications, petroleum samples need to be directly and independently filled in a water body, and for surface water samples, columnar samples are collected from the water surface to 300mm below the water surface, and meanwhile, proper space needs to be left when the samples reach the water surface so as to prevent the loss of oil content.

The special complex composition and physical and chemical properties of petroleum cause much interference to accurate sampling, and the existing sampling technology of petroleum in water has the following defects: the direct filling of the columnar sample easily causes various external pollution or interference on a sampling path; the poor distribution uniformity of petroleum in a water body enables the single inlet sampling of the existing sampling bottle to easily cause the poor representativeness of the sample; the hydrophobicity of oils is very likely to cause the adsorption loss of oil samples, so the solution is urgently needed.

All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a sampling device for underwater petroleum samples includes a sampling bottle 1 entering a water body for sampling, wherein the sampling bottle 1 is fixed in a fixing base 2 matched with the shape of the sampling bottle and is clamped and matched with the fixing base 2. The top of the fixed seat 2 is uniformly provided with auxiliary lifting ropes 21, the lengths of the auxiliary lifting ropes 21 are equal, one end, far away from the fixed seat 2, of each auxiliary lifting rope 21 is fixedly connected with a main lifting rope 22, and the main lifting rope 22 and the auxiliary lifting ropes 21 jointly form a lifting assembly.

During sampling, the main lifting rope 22 and the sampling bottle 1 are positioned on the same axis, and a sampling person can control the sampling depth of the sampling bottle 1 by rolling the main lifting rope 22 by hand.

The bottom of the fixed seat 2 can be provided with a balancing weight, so that the sampling bottle 1 can advance along the vertical direction for sampling after entering the water body.

The main lifting rope 22 is provided with positioning rings 221 at intervals, the positioning rings 221 are coated with fluorescent marks and have bright colors, and the colors of the positioning rings 221 are different to correspond to different depths.

During sampling, the approximate sampling depth of the sampling bottle 1 can be obtained by observing the position of the positioning ring 221. In addition, the main lifting rope 22 may be provided with scale marks to further clarify the water level depth.

The top of the sampling bottle 1 is provided with a non-sampling port 11 positioned on the axis of the bottle body, the upper part of the sampling bottle 1 extends outwards to form at least one sampling port 12 which is obliquely arranged, and the mouth part of the sampling port 12 is positioned outside the projection range of the lifting component along the vertical direction.

The sampling ports 12 are uniformly arranged around the non-sampling port 11, the sampling ports 12 and the non-sampling port 11 are both tubular structures, and the openings of the ports are upward.

The mouth height of the sampling port 12 is not higher than that of the non-sampling port 11. The sampling port cover body 121 is sealed by covering the opening portion of the sampling port 12, and each sampling port cover body 121 is connected to a sampling port cover body lifting rope 122. After the sampling bottle 1 reaches the sampling surface with the preset depth, the sampling opening cover body lifting rope 122 pulls the sampling opening cover body 121 to separate from the sampling opening 12, so that the sampling process can be started, and meanwhile, the sampling opening cover body lifting rope 122 is slightly screwed down to enable the sampling opening cover body 121 to be positioned at the lower part of the sampling opening 12. During sampling, the sampling bottle 1 samples at a fixed depth, or a cylindrical water sample is collected by lifting the main lifting rope 22.

The non-sampling port 11 is in threaded fit with the non-sampling port cover body 111, after sampling is completed, the non-sampling port cover body 111 is screwed lightly, compressed air in the non-sampling port 11 is discharged outwards at the moment, the liquid level in the non-sampling port 11 rises, and the liquid level in the sampling port 12 falls so as to adjust the water level height of a water sample in the sampling bottle 1, and then the non-sampling port and the sampling port are tightly covered. Because the water sample does not fill the non-sampling port and the sampling port of the sampling bottle 1, the loss of the content of the sample during analysis can not be caused. The non-sampling port cover 111 may be a plug-type structure that is tightly combined with the non-sampling port 11.
