Description

Technical Field

[0001] The present invention belongs to the technical field of ship propulsion devices, and in particular relates to a ship turning auxiliary propulsion device. Background Art

[0002] A ship is a means of transport or operation that sails in water. It has different technical performance, equipment and structural types according to different usage requirements. Its interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. The shape is generally streamlined to overcome fluid resistance, and the materials are constantly updated with the advancement of science and technology.

[0003] Existing ships generally turn by deflecting the stern rudder. There are also some methods that directly drive the ship to turn by a deflection drive device, but the deflection angle is limited, resulting in a large turning radius of the ship, which is not convenient for flexible turning in a small area.

The device includes a supporting frame, a driving mechanism, a pushing steering mechanism, etc. The supporting frame is arranged on the ship, the driving mechanism is arranged on the supporting frame, and the pushing steering mechanism is also arranged on the supporting frame, and the purpose of driving the ship to turn is achieved by driving the deflection of the spiral blade;

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0045] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] See also Figure 1 As shown, the present invention provides a ship turning auxiliary propulsion device, comprising: a water jet propulsion pipe 1 for ship auxiliary propulsion, a low-pressure water storage tank 2 and a high-pressure water storage tank 3 for storing water, and a boosting mechanism 4 for changing the pressure of the water storage tank; a passage 1 5 and a passage 2 6 are respectively arranged between the low-pressure water storage tank 2 and the boosting mechanism 4, the high-pressure water storage tank 3 and the boosting mechanism 4 are connected through a passage 3 7, and the high-pressure water storage tank 3 and the water jet propulsion pipe 1 are connected through a passage 4 8; wherein the water jet propulsion pipe 1 is rotatably connected to the bottom of the ship, and a connecting plug 12 is installed at the top of the water jet propulsion pipe 1, and the connecting plug 12 is rotatably arranged inside the adapter tube 14; the ship is assisted in propulsion by spraying water from the water jet propulsion pipe 1, and the direction of the sprayed water flow and the direction of the ship's travel are made to present a certain angle through the rotation of the water jet propulsion pipe 1, so as to achieve the propulsion of the ship's turning travel;

[0047] When the ship needs to make a turning operation, the water jet propulsion pipe 1 sprays water at high speed to obtain reverse thrust, thereby driving the ship to travel. In addition, while the water jet propulsion pipe 1 sprays water, the driving mechanism 13 drives the water jet propulsion pipe 1 to deflect in the horizontal direction, and the water jet propulsion pipe 1 is adjusted to form a certain angle with the stern, so that the ship obtains thrust at a certain angle to the travel direction of the ship, thereby driving the ship to turn;

[0048] The water jet propulsion pipe 1 is used to spray high-speed water flow to obtain thrust, thereby driving the ship to turn, and the water jet propulsion pipe 1 can rotate 360° in all directions. It can be deflected according to the actual turning needs of the ship, and the deflection angle will not be limited, so that the turning radius of the ship can be smaller and the turning is more flexible. In addition, the power is obtained by spraying water instead of rotating the blades, which can prevent the high-speed rotation of the blades in the diving area or the area near the shore from stirring up impurities and hitting the blades to cause damage, and can better protect the ship's driving device.

[0049] Please refer to Figure 2 and Figure 3 As shown, a toothed disc 11 is installed on the outer side of the water jet propulsion pipe 1, and a driving mechanism 13 is meshedly connected to the outer side of the toothed disc 11. The rotation angle of the water jet propulsion pipe 1 is 360°, and the structure of the water jet propulsion pipe 1 is an "L"-shaped structure. The water discharge direction of the water jet propulsion pipe 1 is horizontal.

[0050] In this embodiment, the rotation of the water jet propulsion pipe 1 is driven by a driving mechanism 13, and the engagement of the driving mechanism 13 with the toothed disc 11 drives the water jet propulsion pipe 1 to deflect in the horizontal direction. The "L"-shaped structure of the water jet propulsion pipe 1 can facilitate the installation of the toothed disc 11 on the vertical pipe of the water jet propulsion pipe 1, so as to drive the water jet propulsion pipe 1 to rotate in the horizontal direction. The vertical pipe of the water jet propulsion pipe 1 sprays water in the horizontal direction to obtain thrust, and the water jet propulsion pipe 1 is connected to the adapter tube 14 through the connecting plug 12. When the water jet propulsion pipe 1 rotates, it will drive the connecting plug 12 and the adapter tube 14 to rotate. However, the connecting plug 12 and the adapter tube 14 are always in a tight and connected state, and the connection between the two is not restricted, so that the water jet propulsion pipe 1 can rotate 360° in all directions.

[0051] In a preferred embodiment, please refer to Figure 4 and Figure 5 As shown, the upper end of the low-pressure water storage tank 2 is connected to a filter mechanism 21, and the filter mechanism 21 includes a filter box 211 connected to the top of the low-pressure water storage tank 2, and a filter plate 212 is obliquely arranged on the inner side of the filter box 211. The top of the filter box 211 is provided with an end cover 214, and the end cover 214 is connected to a water inlet pipe 215;

[0052] In this embodiment, the water pumped into the low-pressure water storage tank 2 is first filtered by the filtering mechanism 21 and then flows into the low-pressure water storage tank 2 for storage, so as to prevent impurities from entering the interior of the device and causing blockage, thereby avoiding damage to the interior of the device;

[0053] When water is poured into the low-pressure water storage tank 2, the water first enters the filter box 211 through the water inlet pipe 215 on the end cover 214, and then flows into the low-pressure water storage tank 2 after being filtered by the filter plate 212 in the filter box 211, thereby filtering out impurities and preventing impurities from clogging the pipe. In addition, the filter plate 212 is arranged at an angle, and an opening 213 is provided on the inclined side of the filter plate 212. Due to the inclined placement of the filter plate 212, impurities can easily move to the side of the opening 213, and it is convenient to clean out the impurities from the opening 213, so as to improve the filtering capacity of the filter plate 212. In addition, when the filter mechanism 21 performs filtering work normally, the opening 213 is blocked.

[0054] Secondly, please refer to Figure 6 As shown, one end of the passage 15 is connected to the bottom end of the low-pressure water storage tank 2, and the other end of the passage 15 is connected to the boosting mechanism 4. The passage 15 is also provided with a control valve 151 for controlling the opening and closing of the passage and a one-way valve 152 for controlling the flow direction of the passage. The control flow direction of the one-way valve 152 flows from the side of the low-pressure water storage tank 2 to the side of the boosting mechanism 4. One end of the passage 37 is connected to the bottom end of the high-pressure water storage tank 3, and the other end of the passage 37 is connected to the boosting mechanism 4. The passage 37 is respectively provided with a control valve 371 and a one-way valve 372. The internal medium flow direction of the one-way valve 372 flows from the side of the boosting mechanism 4 to the side of the high-pressure water storage tank 3.

[0055] In this embodiment, the low-pressure water storage tank 2 is connected to the boosting mechanism 4 by means of passage 1 5, so that the boosting mechanism 4 can absorb water from the low-pressure water storage tank 2. In the actual operation process, the water can be pumped from the low-pressure water storage tank 2 into the boosting mechanism 4 by means of the connection of passage 1 5, and then the water in the boosting mechanism 4 can be sent to the high-pressure water storage tank 3 through passage 3 7 by means of the push of the boosting mechanism 4, so as to achieve the purpose of transporting the water from the low-pressure water storage tank 2 to the high-pressure water storage tank 3. In addition, when the water is transported from the low-pressure water storage tank 2 to the high-pressure water storage tank 3 through passage 1 When passage 1 5 and passage 3 7 realize water transportation, other passages are in a closed state, passage 1 5 and passage 3 7 are opened by control valve 1 51 and control valve 3 71 respectively, and the function of one-way valve 1 52 is to prevent the water from flowing back to the low-pressure water storage tank 2 through passage 1 5 when the boosting mechanism 4 pushes water to the high-pressure water storage tank 3, and the function of one-way valve 3 72 is to prevent the water cup in the high-pressure water storage tank 3 from being sucked into the boosting mechanism 4 to cause reflux when the boosting mechanism 4 absorbs water from the low-pressure water storage tank 2.

[0056] Please refer again Figure 7 As shown, one end of the second passage 6 is connected to the top of the low-pressure water storage tank 2, and the other end of the second passage 6 is connected to the boosting mechanism 4. The second passage 6 is provided with a control valve 61 and a check valve 62, respectively. The flow direction of the internal medium of the check valve 62 flows from the side of the low-pressure water storage tank 2 to the side of the boosting mechanism 4.

[0057] In this embodiment, the low-pressure water storage tank 2 is connected to the boosting mechanism 4 from the top through the passage 2 6. The boosting mechanism 4 sucks away the air inside the low-pressure water storage tank 2 through the passage 2 6, so that the inside of the low-pressure water storage tank 2 becomes a relative vacuum state, which is convenient for the low-pressure water storage tank 2 to absorb water into the tank. In addition, the passage 2 6 is connected to the top of the low-pressure water storage tank 2 to prevent the water in the low-pressure water storage tank 2 from being accidentally sucked into the boosting mechanism 4. When the low-pressure water storage tank 2 is storing water, except for the passage 2 6 being opened by the control valve 2 61 and the passage 4 8 being opened when the boosting mechanism 4 is exhausted to the outside, other passages are in a closed state. In actual operation, the air in the low-pressure water storage tank 2 is sucked away by the boosting mechanism 4 to form a negative pressure state, which makes it easier for the low-pressure water storage tank 2 to absorb water for storage. When the boosting mechanism 4 is full of air, the control valve four 81 on the passage four 8 is opened to allow the sucked air to be discharged, making it easier for the boosting mechanism 4 to absorb the air from the low-pressure water storage tank 2 again. When the boosting mechanism 4 absorbs the air from the low-pressure water storage tank 2, the control valve four 81 is in a closed state, and the function of the one-way valve two 62 is to control the flow direction of the fluid in the passage two 6 to prevent the fluid in the boosting mechanism 4 from flowing back into the low-pressure water storage tank 2.

[0058] See also Figure 8 As shown, the boosting mechanism 4 includes a boosting cylinder 41 for connecting the passage, a boosting plunger 42 is movably arranged in the boosting cylinder 41, and a telescopic rod 43 is connected to the boosting plunger 42;

[0059] In this embodiment, the boosting mechanism 4 mainly functions to store water in the low-pressure water storage tank 2 and the high-pressure water storage tank 3, and secondly to change the pressure in the high-pressure water storage tank 3, so that the pressure in the high-pressure water storage tank 3 is increased to facilitate the water jet propulsion pipe 1 to spray high-speed and high-pressure water flow, thereby facilitating the movement and steering of the ship;

[0060] When the boosting mechanism 4 is in use, the boosting plunger 42 is driven to move in the boosting cylinder 41 toward the side away from the passage by retracting the telescopic rod 43, so that the fluid in the low-pressure water storage tank 2 or the outside world can be sucked into the boosting cylinder 41, and then the boosting plunger 42 is driven to move in the boosting cylinder 41 toward the side close to the passage by extending the telescopic rod 43, so that the fluid in the boosting cylinder 41 can be pushed out, thereby achieving the purpose of fluid transfer flow.

[0061] See also Figure 6 and Fig. 9 As shown, a pressure relief pipe 31 is connected to the top of the high-pressure water storage tank 3, and a pressure relief valve 32 is installed on the pressure relief pipe 31;

[0062] In this embodiment, when the low-pressure water storage tank 2 is filled with water into the high-pressure water storage tank 3 through the passage 1 5 and the passage 3 7, the pressure relief valve 32 on the pressure relief pipe 31 can be opened, so that while the high-pressure water storage tank 3 is filled with water, the air in the high-pressure water storage tank 3 can be discharged from the pressure relief pipe 31, thereby preventing the pressure in the high-pressure water storage tank 3 from being too high and making it difficult to inject water;

[0063] One side of the boost cylinder 41 is also connected to an air pipeline 9, on which a control valve 5 91 is provided. One end of the passage 48 is connected to the bottom of the high-pressure water storage tank 3, and the other end of the passage 48 is connected to the top of the adapter cylinder 14. The passage 48 is provided with a control valve 481 for controlling the opening and closing of the passage.

[0064] When the ship needs to turn, it is necessary to open the control valve four 81 so that the water in the high-pressure water storage tank 3 can flow out from the water jet propulsion pipe 1, thereby obtaining thrust, which can assist in driving the ship to travel or turn. In order to keep the water flow out of the water jet propulsion pipe 1 in a high-speed and high-pressure state, so as to better obtain power, the high-pressure water storage tank 3 can be pressurized by the boosting mechanism 4. The specific operation is as follows: while opening the control valve four 81, the control valve three 71 on the passage three 7 and the control valve five 91 on the air pipeline 9 can be opened, and the air pipeline 9 is used to allow the boosting mechanism 4 to absorb external air, and then the control valve five 91 is closed, and then the air in the boosting mechanism 4 is injected into the high-pressure water storage tank 3 through the passage three 7, so as to achieve the purpose of pressurizing the high-pressure water storage tank 3. In this way, the reciprocating cycle is repeated, and air is continuously injected into the high-pressure water storage tank 3 through the boosting mechanism 4, and the water in the high-pressure water storage tank 3 is squeezed out from the water jet propulsion pipe 1 by the air, so that the water flow ejected from the water jet propulsion pipe 1 has the properties of high speed and high pressure;

[0065] In addition, in addition to increasing the pressure of the high-pressure water storage tank 3 by injecting air into the high-pressure water storage tank 3, the pressure can also be increased by continuously injecting water from the low-pressure water storage tank 2 into the high-pressure water storage tank 3 while the high-pressure water storage tank 3 sprays water outward through the water jet propulsion pipe 1. The injection method is the same as the previous method of injecting water from the low-pressure water storage tank 2 into the high-pressure water storage tank 3, and will not be repeated here.

[0066] The working principle of the present invention is as follows: when a ship needs to make a turning operation, a reverse thrust is obtained by spraying water at high speed through the water jet propulsion pipe 1, thereby driving the ship to travel. In addition, while the water jet propulsion pipe 1 sprays water, the water jet propulsion pipe 1 is driven by the driving mechanism 13 to deflect in the horizontal direction, and a certain angle is formed with the stern through the adjustment of the water jet propulsion pipe 1, so that the ship obtains a thrust at a certain angle to the travel direction of the ship, thereby driving the ship to turn.

[0067] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
