Description

TECHNICAL FIELD

[0001] The present application relates to the desalination of seawater, in particular to a seawater desalination system for a nuclear power platform. BACKGROUND

[0002] For a nuclear power platform at sea, fresh water is a necessity for daily life. Due to the special role of the nuclear power platform at sea and the marine environment in which it is located, the storage of fresh water is limited, and the use of fresh water is basically non-recyclable. Although the used fresh water can be treated and reused, the treated water is difficult to meet the standard of domestic water. Therefore, desalination of seawater on site has become one of the important sources of fresh water for the nuclear power platform at sea. However, the current commonly used seawater desalination consumes a large amount of energy. If the seawater desalination consumes a large amount of energy, it will inevitably reduce the energy required for the operation of other equipment. In addition, in the process of seawater desalination, the acquisition of seawater becomes an important factor restricting the efficiency of seawater desalination. Because the seawater needs to be extracted from the sea to the nuclear power platform at sea, additional power is required, for example, using a water pump to pump up the seawater requires the water pump to be powered by an electric power source. This requires a large amount of electric energy, and electric energy is not abundant on the nuclear power platform at sea. Therefore, how to economically and quickly obtain seawater from the sea has become a technical problem to be solved. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art and provide a seawater desalination system for a nuclear power platform, which can quickly obtain seawater required for seawater desalination without additional driving force.

[0004] The technical scheme adopted to achieve the object of the present application is a seawater desalination system for a nuclear power platform, which comprises a first sliding groove and a U-shaped sliding pipe arranged on the outer wall of the hull. The outer wall of the bottom of the U-shaped sliding pipe is provided with a sliding rail, the sliding rail is clamped into the first sliding groove, and the U-shaped sliding pipe can slide into seawater along the first sliding groove. The U-shaped sliding pipe is hollow, the inner wall of the U-shaped sliding pipe is provided with a second sliding groove, and the U-shaped sliding pipe is provided with a U-shaped opening along the pipe wall. The U-shaped sliding pipe is provided with a first sliding block and a second sliding block, the two sliding blocks are respectively clamped into the second sliding groove and can freely slide, the two sliding blocks are connected by a hard spring, and the two sliding blocks are connected to a driver. The first sliding block is connected to a first hook, the second sliding block is connected to a second hook, a water taking pipe is hung on the first hook, and the water taking pipe forms a certain angle with the sea surface. A water discharge pipe is hung on the second hook, and the capacity of the water taking pipe is less than that of the water discharge pipe.

[0005] In the above technical scheme, the driver can be connected to the controller on the hull by wired connection or wireless connection. The controller can control the operation of the driver, and the operation of the driver can drive the two sliding blocks to slide along the second sliding groove.

[0006] The capacity of the drain pipe used in this invention is greater than that of the intake pipe. Therefore, after the drain pipe is filled with wastewater, the intake pipe can be automatically driven to move upward under the weight of the fully loaded drain pipe during the sinking process, thereby realizing the transportation of seawater from the sea surface to the ship deck. In this process, no additional driving force is required to lift the intake pipe, thus eliminating the need for the electrical energy required to extract seawater by water pump in the prior art.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] like Figure 1 As shown, the seawater desalination system for nuclear power platforms of the present invention includes a first chute and a U-shaped slide tube 1 located on the outer wall of the hull. The outer wall of the bottom of the U-shaped slide tube 1 is provided with a slide rail 3, which is inserted into the first chute. The U-shaped slide tube can slide into the seawater along the first chute.

[0012] The U-shaped slide tube 1 is hollow, and the inner wall of the U-shaped slide tube 1 is provided with a second sliding groove. The U-shaped slide tube 1 has a U-shaped opening 2 along the tube wall. The U-shaped slide tube 1 is provided with a first slider 4 and a second slider 5. The two sliders are respectively inserted into the second sliding groove and can slide freely. The two sliders are connected by a rigid spring, and both sliders are connected to a driver. Both sliders are connected to hooks through a connecting rod. Specifically, the connecting rod passes through the U-shaped opening 2 and is connected to the first slider 4 at one end inside the U-shaped slide tube 1, and to the second slider 5 at the other end outside the U-shaped slide tube 1. The first slider 4 is connected to the first hook, and the second slider 5 is connected to the second hook. A water intake pipe 6 is hung on the first hook, and the water intake pipe 6 is at a certain angle to the sea surface 8. A water discharge pipe 7 is hung on the second hook. The capacity of the water intake pipe 6 is smaller than the capacity of the water discharge pipe 7.

[0013] The actuator can be connected to the controller on the hull via wired connection or wireless connection via Bluetooth. The controller can control the actuator to operate, and the actuator can drive the two sliders to slide along the second groove.

[0014] When the U-shaped slide tube slides down to the lowest point along the first slide groove, the top of the U-shaped slide tube is higher than the ship's deck.

[0015] The working process of the seawater desalination system for the nuclear power platform is as follows:

[0016] After the water taking pipe 6 is hung on the first hook, the water taking pipe 6 slides to the sea surface due to the gravity, and since the water taking pipe 6 floats on the sea surface, seawater cannot enter the water taking pipe 6. At this time, the controller controls the drive on the first sliding block 4 to work, and the drive drives the first sliding block 4 to continue to sink below the sea surface 8 until the water taking pipe opening sinks into the sea surface. At this time, seawater enters the water taking pipe 6, and since the first sliding block 4 descends, the second sliding block 5 is pushed to move upward in the U-shaped sliding pipe 1 until it reaches the top near the one-side pipe opening of the U-shaped sliding pipe 1, as shown in FIG. 2. Figure 2 The waste water after seawater desalination is loaded into the water discharging pipe 7. At this time, since the capacity of the water taking pipe 6 is smaller than that of the water discharging pipe 7, the weight of the water discharging pipe 7 is greater than that of the water taking pipe 5. The water discharging pipe 7 descends and drives the second sliding block 5 to sink below the sea surface, and at the same time, the first sliding block 4 drives the water taking pipe 6 to move upward until it reaches the top near the other pipe opening of the U-shaped sliding pipe 1. At this time, the water taking pipe 6 is located near the ship surface, as shown in FIG. 3. Figure 2 The seawater is obtained from the water taking pipe 5, and then the second sliding block 5 is driven to rotate by the controller, and the pipe opening of the water discharging pipe 7 is rotated downward. Finally, the second sliding block 5 drives the water discharging pipe to move upward by the controller, and the waste water in the water discharging pipe flows into the sea. The water discharging pipe in the empty state is brought upward into the ship surface. In the above process, after the seawater is taken from the water taking pipe, the empty water taking pipe 6 is hung on the first hook, and when the water discharging pipe 7 is brought upward into the ship surface, the water taking pipe 6 sinks below the sea surface until the water taking pipe 6 opening sinks into the sea surface, so as to repeat the above water taking process and cycle the above operation, thereby continuously transporting seawater to the ship surface.

[0017] For the large driving force required for the process of transporting seawater from the sea surface to the ship surface, the capacity of the water discharging pipe 7 used in the present application is greater than that of the water taking pipe 6, so that after the water discharging pipe 7 is filled with waste water, the water taking pipe 6 can be automatically driven to move upward under the self-weight of the full load water discharging pipe 7 during the sinking process, without the need for additional driving force to lift the water taking pipe 6. Compared with the existing technology of extracting seawater by a high-power water pump, the present application only needs to drive the first sliding block 4 to drive the empty water taking pipe 6 below the sea surface, drive the second sliding block 5 to rotate the pipe opening of the water discharging pipe 7 downward, and drive the second sliding block 5 to drive the empty water discharging pipe 7 to move upward. These driving processes only require a small driving force.
