[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] The utility model provides a seawater taking device for a polar scientific research station, comprising a water intake pipe 1, a connecting pipe 2, a water storage tank 3 and a base 4, wherein the base 4 is fixed at the bottom of the water storage tank 3, the base 4 is made of heavy stainless steel, at least one side of the water storage tank 3 is a grid plate 5, the water storage tank 3 and the base 4 are both below the sea level, the water intake pipe 1 and the connecting pipe 2 are arranged in the water storage tank 3, the opening of the water intake pipe 1 faces the grid plate 5, a part of the connecting pipe 2 extends out of the water storage tank 3, one end of the connecting pipe 2 located in the water storage tank 3 is connected to the outlet of the water intake pipe 1, and a check valve 6 is arranged on the water intake pipe 1, and the inlet of the check valve 6 faces the opening of the water intake pipe 1.

[0036] The seawater automatically enters the water storage tank 3 through the grid plate 5, and the water in the water storage tank 3 enters the water intake pipe 1, and then enters the connecting pipe 2. Because the connecting pipe 2 is connected to the pipeline system fixed on the seabed slope, the seawater is continuously transported out. The setting of the grid plate 5 can filter out seaweed and other marine organisms in advance to prevent them from clogging the water intake pipe 1 and hindering subsequent water intake, and it is also beneficial to the maintenance of the seawater intake device.

[0037] The check valve 6 can prevent the seawater flowing into the water intake pipe 1 from flowing back into the sea.

[0038] A vertical full-rotation recoiler 7 is also provided on the water intake pipe 1, the inlet of the full-rotation recoiler 7 is connected to the water intake pipe 1, the outlet of the full-rotation recoiler 7 is located above the inside of the water storage tank 3, facing the grid plate 5, and the check valve 6 is located between the opening of the water intake pipe 1 and the full-rotation recoiler 7. When the grid plate 5 needs to be cleaned, the full-rotation recoiler 7 is directly opened, and the water in the water intake pipe 1 is sprayed through the water intake pipe 1, the check valve 6, and the outlet of the full-rotation recoiler 7 in sequence to clean the grid plate 5, and the sundries blocked on the grid plate 5 are washed away.

[0039] In the embodiment of the utility model, two opposite grid plates 5 are arranged on the water storage tank 3. Of course, the number of grid plates 5 can also be 3, 4, etc., and can be set according to actual conditions. In order to adapt to the number of grid plates 5, the utility model sets two water intake pipes 1, and the water entering one grid plate 5 enters one water intake pipe 1 accordingly.

[0040] The top of the water storage bin 3 is provided with an opening, and the opening is provided with an openable upper cover 31, which is convenient for installing the water intake pipe 1, the connecting pipe 2 and the full-rotation recoiler 7 inside the water storage bin 3 during assembly. After installation, the upper cover 31 is covered.

[0041] A lifting ring 8 is fixed on the upper cover 31, and a reinforcing rib 9 is provided between the lifting ring 8 and the upper cover 31. The reinforcing rib 9 can prevent the lifting ring 8 from being subjected to concentrated force during lifting, thereby avoiding the problem of the lifting ring 8 being easily dropped off. The lifting ring 8 is conducive to the lifting rope being inserted into the lifting ring 8, so that the seawater extraction device can be lifted into the sea.

[0042] The base 4 includes a base plate 42 and a connecting plate 41. The connecting plate 41 is arched and includes a straight portion 411 and downwardly inclined portions at both ends. A base plate 42 is fixed to the bottom of each downwardly inclined portion 412. The base plate 42 is in contact with the bottom of the coast, while the straight portion 411 of the connecting plate 41 is suspended in the air. Because there are many pebbles of different sizes on the Antarctic coast, the straight portion 411 is suspended in the air to prevent the connecting plate 41 from contacting the pebbles of different sizes, which would cause the base 4 to be unstable.

[0043] The connection form of the base 4 and the water storage tank 3 of the utility model is two embodiments.

[0044] Embodiment 1: The base 4 and the water storage tank 3 are detachable structures. In this way, when inspecting or installing components on the water storage tank 3, it is only necessary to lift and hoist the water storage tank 3, which is relatively light and quick. A socket 12 is provided on the connecting plate 41, and a plug 11 is provided at the bottom of the water storage tank 3. The plug 11 is inserted into the socket 12 to fix the water storage tank 3 and the base 4. The plug 11 is taken out of the socket 12 to separate the water storage tank 3 and the base 4. The upper half of the socket is conical as a whole, and the diameter gradually decreases from the upper end to the middle, which is convenient for people to lift and reset on a small boat on the sea surface without arranging divers to assist, thereby improving the alignment rate of lifting and allowing the plug 11 to be quickly inserted into the socket 12.

[0045] Embodiment 2: The base 4 and the water storage tank 3 can be an integrally formed structure, so that when inspecting or installing components on the water storage tank 3, the base 4 and the water storage tank 3 need to be hoisted and installed at the same time, which is relatively bulky. A connecting rod 10 is used to connect the bottom of the water storage tank 3 and the connecting plate 41, and the connecting rod 10 is fixed to both.

[0046] In order to improve the stability of the seawater extraction device in the sea and prevent it from floating unsteadily, the seawater extraction device further includes a stopper 13, which is vertically arranged below the base plate 42. The tail of the stopper 13 is inserted into the seabed. The setting of the stopper 13 is suitable for the situation where the seabed is sand and gravel.

[0047] In order to improve the stability of the seawater extraction device in the sea and prevent it from floating, the seawater extraction device also includes a conventional stopper plate 14, the thickness side of the conventional stopper plate 14 is downward. The thickness side of the conventional stopper plate 14 is inserted into the seabed. The setting of the stopper plate 14 is suitable for the situation where the seabed is pure mud and sand.

[0048] In order to improve the stability of the seawater extraction device in the sea and prevent it from floating unsteadily, the seawater extraction device further includes a short-tooth stop plate 15, with short teeth below the short-tooth stop plate 15. The short teeth of the short-tooth stop plate 15 are inserted into the seabed. The arrangement of the short-tooth stop plate 15 is suitable for the situation where the seabed is a large stone slab.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
