EMBODIMENTS

[0018] Hereafter the present invention is more detailed explained by the accompanying drawing in conjunction with the specific embodiments:

[0019] As is shown in the FIGS. 1, 2, 3 and 4, a continuous ocean surface water sampling device 4, which comprises a support 5 which may ascend or descend along the stern 2, a sampling pipe 6 for drawing and sampling surface water 3 and hydraulic tanks 7 for driving the support 5 up and down, to send the sampling pipe 6 to the position of surface water 3 are fixed on the support 5, and to promise the support stability during ascending and descending, the hydraulic tanks 7 in the present embodiment are configured to be two, symmetrically provided on either side of the sampling pipe 6 and fixed on the stern 2. Among the prior art, hydraulic tank 7 is a common power component, and will not be explained in details here. A buffer mechanism 8 for avoiding damage to the sampling pipe 6 due to water resistance during travelling is provided on the support 5, the buffer mechanism comprises a buffer room 9 provided on the support 5, the buffer room 9 comprises a buffer cavity 10, and on the buffer room 9 a mounting hole 11 allowing the sampling pipe 6 to pass the buffer cavity 10 is provided, to avoid rigid damage to the sampling pipe 6 due to the water resistance, bore diameter of the mounting hole 11 is bigger than outer diameter of the sampling pipe 6. In the buffer room 9, a flexible supporting assembly allowing the sampling pipe 6 to axially and radially move freely within the mounting hole 11 when a continuous water resistance happens is provided; at the bottom of the sampling pipe 6 a depth transducer 12 to check the distance from the sampling pipe water inlet to the water surface is provided; a control unit is provided too, while the depth transducer 12 detects signals of the water inlet position, and sends them to the control unit, which will receive the position signals and deliver a signal controlling working status of the hydraulic tank 7, which will push the support 5 to pose the sampling pipe water inlet at the surface water, and after the sampling is done, send quit signal to the hydraulic tank 7, which draws the support 5 and the sampling pipe 6 back. Generally, ocean surface water 3 covers water 20-30 centimeters under the water surface.

[0020] The said continuous ocean surface water sampling device, wherein the flexible supporting assembly comprises a supporting bar 13 provided across the sampling pipe 6 along the water resistance direction to have it fixed inside the buffer cavity 10, a connection adjustment opening 14 is provided radially across the sampling pipe 6, and to avoid water resistance effect on the sampling pipe 6 and leave rigid damage to it, inner diameter of the connection adjustment opening 14 is bigger than diameter of the sampling pipe 6, and supporting bar 13 is located throughout the connection adjustment opening 14 and is fixed onto inner sides of the buffer room 9. A buffer spring 15 for undermining impact from the water resistance on the sampling pipe 6 and supporting springs 16 for backing the supporting bar are provided on the supporting bar 13. In the present invention, the sampling pipe 6 comprises a rigid submerging pipe 17 fixed on the buffer room 9, a rigid transportation pipe 18 in connection with the rigid submerging pipe 17 and a flexible outlet pipe 19 in connection with the rigid transportation pipe 18 drawing the surface water onboard, the rigid submerging pipe 17 and rigid transportation pipe 18 are connected by a flange 20. Since a sampling pipe 6 of bigger size will be subject to larger influence from water resistance, the said rigid submerging pipe 17 is configured to be of a trapezoid structure, wider on top and shorter down.

[0021] Generally, during travelling, resistance that a sampling pipe 6 is bearing comes primarily from seawater in the navigation direction and transverse water current against the sampling pipe 6, however, resistance due to the transverse water current is usually small, which will not substantially impact the sampling pipe 8, with the buffer mechanism 8, it is not only possible to reduce primary resistance from seawater in the navigation direction, but will also relieve the transverse resistance, which will always promise stable position of the sampling pipe 6.

[0022] Apparently, the above explanation is not a limitation on the present invention, and the present invention shall not be limited to the above embodiments, variations, modifications, addition and replacement made by those of common skill in the art, within the substantial scope of the present invention falls within the protection of the present invention.
