DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with specific embodiments.

[0026] The present application discloses an icebreaker seaport structure with both ice melting and heat exchange functions, which is mainly used for optimizing and improving the seaport structures, especially the water outlet structures, of various types of icebreakers and other ships that need to operate in polar low-temperature environments, and is used to improve the situation where ice and blockage are easy to occur near the seaport in a low-temperature environment.

[0027] like Figure 1As shown, the main structure of the icebreaker seaport structure with both ice melting and heat exchange functions of the present application includes a water outlet pipe seat 1, an outer casing 2, a jet pipe 3, a heat exchange pipeline 5, and a grid plate frame 6;

[0028] The outlet pipe seat 1 is connected to the rear side of the outlet pipe of the icebreaker, and the outer sleeve 2 is connected to the rear side of the outlet pipe seat 1;

[0029] The outer sleeve 2 has a front diameter smaller than a rear diameter, forming a trumpet structure;

[0030] The jet tube 3 is arranged in the outer sleeve 2, and the front diameter of the jet tube 3 is larger than the rear diameter, presenting a funnel-shaped structure;

[0031] The front side of the jet tube 3 and the front side of the outer sleeve 2 form an annular drainage port 1a, the outer wall of the jet tube 3 and the inner wall of the outer sleeve 2 form a heat exchange channel 1b of a rotating body structure, and the front half of the jet tube 3 is evenly provided with a plurality of jet holes 1c;

[0032] The heat exchange pipeline 5 includes heat exchange tubes 50 uniformly arranged in the heat exchange channel 1b;

[0033] The grid plate frame 6 is buckled on the rear end pipe opening of the outer sleeve 2.

[0034] In the present application, the outlet pipe seat 1 is connected to the outlet pipe of the propagation water circulation pipeline, and at the same time serves as a supporting connection structure to ensure the stability of the outer sleeve lamp structure after installation. If necessary, the outer sleeve 2 and the jet tube 3 should be provided to support, fix or insulate the outside of the device. The outer sleeve 2 and the jet tube 3 form a diversion and diversion structure for diverting the water discharged from the ship so that it enters the heat exchange channel 1b and the jet tube 3 respectively. The water pressure and flow rate are changed by the change of the cross-sectional area of ​​the flow channel during the flow process to meet the requirements of low-flow heat exchange and high-flow flushing functions; the low-flow water flow can contact the heat exchange pipeline 5 for a longer time and absorb heat more fully, and the high-flow water flow is compressed and then sprayed to flush the crushed ice on the rear grid frame and the surrounding area.

[0035] like Figure 2 , Figure 3 As shown, as a preferred embodiment, the heat exchange pipeline in the present application includes: a plurality of U-shaped heat exchange tubes 50 arranged in a circular array in the heat exchange channel 1b, and an annular high-temperature water inlet pipe 51 and an annular low-temperature water return pipe 52 respectively connected to the two arms of the heat exchange tube 50; wherein the annular high-temperature water inlet pipe 51 and the annular low-temperature water return pipe 52 are connected to the refrigeration cycle circuit of the icebreaker, and the high-temperature fluid entering the heat exchange tube 50 is heat-exchanged with the low-speed low-temperature fluid entering the heat exchange channel to generate a heated fluid for melting ice and de-icing.

[0036] In order to meet the requirements of the size of the heat exchange channel, as a conventional solution, the outer sleeve 2 is a cylindrical shape with a small front and a large rear, or a conical cylinder or a rectangular cone-shaped structure; the jet tube 3 is a cylindrical shape with a large front and a small rear, or a conical cylinder or a rectangular cone-shaped structure; the inner and outer walls of the two form a heat exchange channel 1b with a small front size and a large rear size.

[0037] The jet tube 3 is a cylindrical structure, wherein the outer wall and the inner wall of the jet tube 3 are respectively provided with spiral guide wings 30, the spiral guide wings are located at the rear side of the jet hole 1c, and the rotation direction of the inner and outer spiral guide wings is consistent. The use of the inner and outer spiral guide wings can cause the fluid in the heat exchange channel and the jet tube to form a swirl in a fixed direction, realize continuous directional ablation and flushing, further improve the ice removal effect, and remove the crushed ice along a fixed direction at the same time, avoiding complex turbulent backflow to form the winter solstice crushed ice backflow to the deicing interval. It should be noted that the aforementioned shape and structure description is used to limit the corresponding basic structural form. In actual use, in order to control the fluid, improve heat exchange, etc., in actual use, it can also be locally optimized or modified based on its basic structure to further produce different functions.

[0038] In particular, in order to flexibly control the deicing water temperature according to the actual water outlet temperature and the medium temperature in the heat exchange tube, it is necessary to be able to more flexibly control the flow ratio of the fluid entering the jet tube of the heat exchange channel. For this reason, in this embodiment, a position adjustment mechanism is also provided inside the outer sleeve 2, wherein the jet tube 3 is installed on the position adjustment structure so as to be slidable forward and backward.

[0039] The position adjustment mechanism changes the size of the annular drainage port 1a by controlling the forward and backward movement of the jet tube, thereby controlling the flow ratio of the fluids entering the two locations.

[0040] As a solution that is easy to implement, the adjustment mechanism can use an adjustment rod 7 directly connected to the jet tube 3, and a linear drive device for driving the adjustment rod to move forward and backward.

[0041] In the actual implementation process, the linear drive device can be configured in different positions according to needs, such as the water outlet pipe seat, the inside and outside of the outer casing, etc.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
