[0030] Please refer to Figures 1 to 5 , the present invention provides a technical solution:

[0031] Embodiment 1

[0032] The structure of a marine water temperature regulator includes: a heat exchange cylinder and a movable housing 7.

[0033] Specifically, the heat exchange cylinder includes an inner cylinder 1 and an outer cylinder 2 which are concentrically arranged. There is a gap between the inner cylinder 1 and the outer cylinder 2 to form the hollow structure of the heat exchange cylinder. The circulating cooling water flows in the inner cavity of the heat exchange cylinder. A flow guide plate 3 fixedly connected to the inner cylinder 1 is arranged in the inner cavity of the heat exchange cylinder. The flow guide plate 3 is in the shape of a spiral auger. The flow guide plate 3 is used to guide the flow of the circulating cooling water and extend the flow path of the circulating cooling water to ensure that the seawater in the middle of the heat exchange cylinder can fully heat and cool the circulating cooling water. The inner side wall of the inner cylinder 1 is fixedly connected with heat exchange fins 6. A plurality of heat exchange fins 6 are provided and distributed in an annular array. The heat exchange fins 6 are arranged to increase the contact area between the seawater and the heat exchange cylinder to improve the heat exchange effect between the seawater and the circulating cooling water. At both ends of the upper part of the outer side wall of the outer cylinder 2, a water inlet pipe 4 and a water outlet pipe 5 are respectively fixedly arranged, and both the water inlet pipe 4 and the water outlet pipe 5 are communicated with the inner cavity of the heat exchange cylinder. Both ends of the inner cavity of the heat exchange cylinder are sealed by annular plates. The water inlet pipe 4 and the water outlet pipe 5 are respectively used to introduce the circulating cooling water into the inner cavity of the heat exchange cylinder and discharge the circulating cooling water;

[0034] Secondly, the movable housing 7 is rotatably installed on the outside of one end of the heat exchange cylinder. The movable housing 7 can rotate. The movable housing 7 is arranged in the shape of a hemispherical shell. A plurality of uniformly distributed filter holes 8 are formed through the surface of the movable housing 7. The filter holes 8 are arranged to filter weeds and sundries in the seawater. A plurality of strip-shaped rib plates 9 distributed in an annular array are fixedly connected to the outer side wall of the movable housing 7. The strip-shaped rib plates 9 are inclined and are arranged in an arc shape. When the outer cylinder 2 moves in the seawater as the ship moves, the seawater passes through the filter holes 8 on the surface of the movable housing 7 and enters the middle of the heat exchange cylinder to heat and cool the circulating cooling water in the inner cavity of the heat exchange cylinder. The movable housing 7 is impacted by the seawater and can rotate under the guiding action of the strip-shaped rib plates 9, so as to throw away the weeds and sundries attached to the surface of the movable housing 7 to prevent the filter holes 8 from being blocked and affecting the normal flow of the seawater, thereby ensuring that the seawater can normally heat and cool the circulating cooling water.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, in order to adjust the position of the heat exchange cylinder, the present application further has corrugated connecting pipes 10 fixedly connected to the upper ends of both the water inlet pipe 4 and the water outlet pipe 5. The upper ends of the corrugated connecting pipes 10 are fixedly connected with flange connectors 11. The flange connectors 11 are fixedly connected to the ends of the circulating water pipes. The circulating water pipes are used to send the circulating cooling water to the equipment that needs to be cooled inside the ship. A hydraulic telescopic rod 12 is fixedly connected to the surface of the heat exchange cylinder. The hydraulic telescopic rod 12 is fixed on the lower surface of the ship's hull. The hydraulic telescopic rod 12 is arranged to adjust the position of the device. At the same time, a groove is opened on the lower surface of the ship for storing the device, so as to prevent the device from being damaged due to collision when not in use.

[0037] Embodiment III

[0038] On the basis of Embodiment II, in order to describe in detail the rotational connection between the movable housing 7 and the heat exchange cylinder, the present application further has a mounting seat 13 provided at one end of the heat exchange cylinder. A plurality of connecting rods 17 distributed in an annular array are fixedly connected to the outer side wall of the mounting seat 13. The end of the connecting rod 17 is fixedly connected to the end of the inner side wall of the inner cylinder 1. Through the connection of the connecting rods 17, the mounting seat 13 can be relatively fixed to the heat exchange cylinder.

[0039] An installation groove 14 is formed in one end face of the mounting seat 13. A positioning groove 15 is formed in the middle of the bottom of the installation groove 14. A fastening groove 16 is annularly formed in the inner side wall of the positioning groove 15. The mounting seat 13 is provided for mounting the movable housing 7.

[0040] Embodiment IV

[0041] On the basis of Embodiment III, in order to position the movable housing 7, the present application further has a central shaft 19 fixedly connected to the middle of the inner side wall of the movable housing 7. One end of the central shaft 19 penetrates through the inner cavity of the installation groove 14 and is movably inserted into the inner cavity of the positioning groove 15. An outer side of one end of the central shaft 19 is fixedly sleeved with a bearing 18. The bearing 18 is located in the inner cavity of the installation groove 14 and is in interference fit with it. The bearing 18 is provided to reduce the friction force when the central shaft 19 rotates, and at the same time can position the central shaft 19 to prevent the separation between the central shaft 19 and the mounting seat 13. That is to say, through the rotational connection between the movable housing 7 and the mounting seat 13 by the central shaft 19, the movable housing 7 can only rotate at the end of the heat exchange cylinder and will not easily move relative to the heat exchange cylinder and cause disengagement.

[0042] Embodiment V

[0043] On the basis of Embodiment IV, in order to seal and protect the bearing 18, the present application further has a mounting platform 20 fixedly provided on the outer side of the other end of the central shaft 19. A plurality of reinforcing plates 25 distributed in an annular array are fixedly connected between the mounting platform 20 and the inner side wall of the movable housing 7. The reinforcing plates 25 are provided to strengthen the connection strength between the central shaft 19 and the movable housing 7 to prevent the central shaft 19 from shifting.

[0044] In addition, an annular sealing plate 22 is movably sleeved on the outer side of one end of the central shaft 19. An annular sealing gasket 23 is bonded to one side surface of the annular sealing plate 22. One side surface of the annular sealing plate 22 is attached to the end surface of the mounting seat 13.

[0045] A compression spring 21 is arranged between the mounting table 20 and the annular sealing plate 22. The two ends of the compression spring 21 are respectively in contact with the annular sealing plate 22 and the mounting table 20. The compression spring 21 is movably sleeved on the outer side of one end of the central shaft 19. The compression spring 21 is provided to compress the annular sealing plate 22, so that the annular sealing plate 22 can closely fit on the end face of the mounting seat 13 to seal and protect the bearing 18, thereby reducing the possibility of seawater and impurities entering the inner cavity of the bearing 18, and thus extending the service life of the bearing 18. Rubber protective sleeves 24 are arranged on both the inner and outer sides of the compression spring 21. The two ends of the rubber protective sleeves 24 are respectively bonded to the annular sealing plate 22 and the mounting table 20. The rubber protective sleeves 24 are provided to seal and protect the compression spring 21 to ensure that the compression spring 21 will not rust during long-term use.

[0046] Embodiment Six

[0047] On the basis of Embodiment Five, in order to prevent the central shaft 19 from easily disengaging from the inner cavity of the positioning groove 15, the present application further has a plurality of ball grooves arranged in an annular array on the outer side wall of one end of the central shaft 19. Positioning balls 26 are rotatably installed in the ball grooves. A thrust spring is arranged in the inner cavity of the ball grooves. One end of the thrust spring abuts against the surface of the positioning balls 26. The ball grooves and the thrust spring are both mature structures in the prior art. The thrust spring provides a thrust force to keep the positioning balls 26 always located at the opening end of the ball grooves, and the positioning balls 26 can roll and rotate in the inner cavity of the fastening groove 16. On the one hand, it reduces the friction between the central shaft 19 and the inner wall of the positioning groove 15, and on the other hand, it can prevent the central shaft 19 from easily disengaging from the inner cavity of the positioning groove 15.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
