Description

Technical Field

[0001] The invention belongs to the technical field of oil spill monitoring, and in particular relates to a sampling device for monitoring oil spill in sea areas. Background Art

[0002] With the rapid development of marine transportation and offshore oil extraction, marine oil spill accidents are becoming more and more frequent, so it is necessary to take water quality samples in the sea area where the oil spill occurs;

[0003] When sampling water quality at an oil spill site, the oil spill monitoring device is used to control the sampler to be inserted into the seawater in the oil spill area. However, the water quality of different oil spill levels varies at different depths on the sea surface. If the sea surface is sampled directly, it is impossible to determine the extent of the oil spill at the oil spill site.

[0004] In view of this, a sampling device for monitoring oil spills in sea areas is proposed. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the prior art: when water quality sampling is conventionally carried out at an oil spill site, the sampler is controlled by an oil spill monitoring device to be inserted into the seawater in the oil spill area. However, the water quality of different oil spill levels is different at the depth of the sea surface. If sampling is carried out directly on the sea surface, it is impossible to determine the extent of the oil spill at the oil spill site.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a sampling device for monitoring oil spills in sea areas, comprising a sampling tube;

[0008] An inner cavity is provided inside the sampling tube, a channel is provided on the surface of the sampling tube, the channel is connected with the inner cavity, and an operating seat is provided at the top of the sampling tube;

[0009] A storage tube is arranged in the inner cavity of the sampling tube, and multiple groups of partition plates are arranged inside the storage tube. A single group of partition plates includes two parallel partitions. There is a storage cavity between the single group of partition plates, and there is a cavity between two groups of partition plates. A sealing gasket is provided for sealing and sliding between the storage cavities, and a piston rod is arranged between the two sealing gaskets. A groove 1 is provided inside the operating seat, and the piston rod at the top passes through the top of the sampling tube and extends into the groove 1. A tooth pattern is provided on the side of one end of the piston rod extending into the groove 1.

[0010] As an optimal technical solution for a sampling device for monitoring oil spills in sea areas, a delivery pipe is provided on the side of the storage tube, and one end of the delivery pipe close to the storage tube is connected to the storage cavity. A sampling head is installed in the channel, and one end of the delivery pipe away from the storage tube is connected to the sampling head, so that the seawater and oil extracted by the sampling head can be introduced into the storage cavity through the delivery pipe.

[0011] As a preferred technical solution for a sampling device for monitoring oil spills in sea areas, a receiving groove is provided above the channel, a sealing plate is sealingly and slidably connected in the receiving groove, the cross-sectional shape of the sealing plate is L-shaped, and the bottom end size of the sealing plate matches the internal size of the channel, and the bottom end of the sealing plate will block the channel after extending out of the receiving groove.

[0012] As an optimal technical solution for a sampling device for monitoring oil spills in sea areas, a storage cavity is provided on the side of the sampling tube close to the storage groove, a threaded rod is rotatably connected in the storage cavity, a plurality of threaded sleeves are threadedly transmitted on the outer side of the threaded rod, and the corresponding threaded sleeves are connected to the sealing plate via a connecting plate. When the threaded rod rotates, the threaded sleeves can link the sealing plate to change position by utilizing the threaded transmission structure.

[0013] As an optimal technical solution for a sampling device for monitoring oil spills in sea areas, the top end of the threaded rod extends through the sampling tube and is provided with a gear 1. The outer periphery of the operating seat is rotatably connected with an external gear sleeve. The external gear sleeve is meshed with gear 1 for transmission, so that when the external gear sleeve is rotated, multiple gears 1 can rotate synchronously.

[0014] As an optimal technical solution for a sampling device for monitoring oil spills in sea areas, a groove 2 is provided on a side of the operating seat close to the groove 1, and a gear 2 is rotatably connected in the groove 2. The gear 2 is meshed with the teeth on one side of the piston rod for transmission, so that when the gear 2 rotates, the meshing transmission can be used to cause the piston rod to retract and extend.

[0015] The beneficial effects of the present invention are as follows: by utilizing the meshing transmission structure between gear 2 and the tooth pattern, the piston rod and the sealing pad can undergo telescopic movement, and under the action of the sampling head and the delivery tube, the water sample can be extracted into the storage chamber. At this time, the sampling heads placed at different heights can sample water quality at different depths in the sea area, and cooperate with the meshing transmission of the outer gear sleeve and gear 1 and the meshing of the threaded rod and the threaded sleeve, so that the sealing plate will block the opening of the sampling head, thereby preventing the water sample from flowing out after sampling.

[0028] Specifically, a delivery pipe 201 is provided on the side of the storage pipe 200, and one end of the delivery pipe 201 close to the storage pipe 200 is connected to the storage chamber 204. A sampling head 202 is installed in the channel 101, and one end of the delivery pipe 201 away from the storage pipe 200 is connected to the sampling head 202, so that the seawater and oil extracted by the sampling head 202 can be introduced into the storage chamber 204 through the delivery pipe 201;

[0029] Specifically, a receiving groove 102 is provided at the upper position of the channel 101, and a sealing plate 103 is sealingly and slidably connected in the receiving groove 102. The cross-sectional shape of the sealing plate 103 is L-shaped, and the bottom end size of the sealing plate 103 matches the internal size of the channel 101. The bottom end of the sealing plate 103 will block the channel 101 after extending out of the receiving groove 102; a receiving cavity 104 is provided on the side of the sampling tube 100 close to the receiving groove 102, and a threaded rod 105 is rotatably connected in the receiving cavity 104. The outer side of the threaded rod 105 is threadedly driven with a plurality of threaded sleeves 106, and the corresponding threaded sleeves 106 are connected to the sealing plate 103 through a connecting plate. When the threaded rod 105 rotates, the threaded sleeve 106 can link the sealing plate 103 to change position by utilizing the structure of threaded transmission;
