DETAILED DESCRIPTION
[0063] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the embodiments will be described in detail below with reference to the drawings. Obviously, the following description is some examples or embodiments of the present specification, and those skilled in the art can also apply the technical solutions or means disclosed in the present specification to other scenarios without creative labor, based on these technical contents.
[0064] It should be understood that the "system", "device", "equipment", "part" and / or "piece" used in the present specification is a method for distinguishing different components, elements, parts, parts or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.
[0065] Unless otherwise specified, the technical terms of components, elements, etc. described in the present specification do not refer to a single number, but can also include a plurality. Generally speaking, the terms "include", "contain" and the like only indicate the inclusion of the steps, elements or components explicitly identified, and these steps, elements and components do not constitute an exclusive list, and the method or device described can also include other steps or components.
[0066] In the description of the present specification, it should be understood that the orientation description, such as the orientation or position relationship indicated by the upper, lower, front, rear, left, right and the like, is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present specification, unless otherwise explicitly limited, the words such as arrangement, installation, connection and the like should be broadly understood, and those skilled in the art can reasonably determine the specific meaning of the above words in the present specification in combination with the specific content of the technical solution.
[0067] In some use scenarios, it is required that the water surface facility can be relatively stationary to avoid displacement caused by external environmental factors such as wind waves, ocean currents, etc. The above use scenarios include but are not limited to sea fishing, and the above water surface facilities include but are not limited to ships, yachts, oil wells.
[0068] In one or more embodiments of the present specification, the top flow machine refers to a propulsion device that keeps the ship body relatively stationary or stationary on the water surface without anchoring the ship, mainly used to resist the influence of wind waves and ocean currents, which can replace the role of the anchor, and is also called electronic anchor, belonging to ship propulsion equipment, and specifically belonging to auxiliary propulsion equipment for ships.
[0069] The top flow machine is usually arranged on the ship side and does not interfere with the ship body main power mechanism. Compared with the ship body main power mechanism with limited steering angle, the top flow machine needs to resist the influence of wind waves and ocean currents in all directions to maintain the relative stability of the ship body posture, so it is required to be able to change direction freely in the circumferential range (i.e. 360 degrees) and be fixed. Therefore, the top flow machine is usually mounted to the outside of the ship body through a base in one or more embodiments of the present specification, so that the entire top flow machine device can extend out of the ship body, provide space for its free rotation in the circumferential range, and provide space for its not affecting the main power mechanism and not interfering with the ship body under water.
[0070] In the case where the top flow machine is not used, in order to avoid additional resistance to ship navigation, it is required to be able to be separated from below the water surface, which is usually provided by a liftable lifting rod, which is usually also configured to be able to rotate around its axis to realize the function of changing direction freely in the circumferential range.
[0071] Further, in the case where the ship is at anchor, in order to save the anchoring volume and avoid damage to the top flow machine device extending out of the ship body due to collision, it is necessary to require the top flow machine device to be moved to the inside of the ship body by rotating (especially revolving around an axis), sliding and the like.
[0072] To this end, some embodiments of the present specification propose a rotating base, which enables the propulsion device, especially the top flow machine device, installed on the rotating base to enter the inside of the ship body at least in a rotating manner, which comprises a first plate structure 1, a second plate structure 2, and a rotating shaft 3. Wherein, the rotating shaft 3 is fixedly connected with the first plate structure 1, the side surface of the rotating shaft 3 is provided with a limiting surface arranged towards the first plate structure 1, the second plate structure 2 is provided with a limiting surface matched with the limiting surface, the second plate structure 2 is limited between the limiting surface and the first plate structure 1, and the second plate structure 2 is configured to be able to rotate relative to the rotating shaft 3.
[0073] In some embodiments, for example Figure 1 As shown, a plurality of fixing holes 12 are arranged on the first plate structure 1, and the plurality of fixing holes 12 are used to fix the first plate structure 1 to the ship body. For example, the first plate structure 1 is fixed to the deck of the ship body, or fixed to the top surface or side surface of the ship body fence, or fixed to the ship side, or fixed to the platform structure attached to the outside of the ship side.
[0074] Referring to Figures 1 to 4 As shown, the second plate structure 2 is located above the first plate structure 1, and the upper surface of the rotating shaft 3 is flush with the upper surface of the second plate structure 2, so as to facilitate the arrangement of other devices above the second plate structure 2. The above-mentioned other devices include but are not limited to a lifting shaft which can be lifted and rotated, a rotating mechanism for rotating the lifting shaft, or a lifting mechanism for driving the lifting shaft to lift.
[0075] In some embodiments, one side of the second plate structure 2 is arranged in a circular arc shape to match the shape of the rotating shaft 3, so as to have better stress performance. The other side of the second plate structure 2 extends outside the first plate structure 1, so that the devices arranged on the second plate structure 2, such as the lifting shaft, can not interfere with the first plate structure 1. The other side of the second plate structure 2 is also provided with a U-shaped groove 23 for avoiding the lifting shaft in a vertical state.
[0076] Specifically, the second plate structure 2 is configured to be operatively rotated to a first position, which is that the U-shaped groove 23 of the second plate structure 2 faces the water surface direction, specifically, the second plate structure 2 points to Figure 1 the right side direction in the figure. When the second plate structure 2 is in the first position, the lifting shaft can be located at the farthest end outside the ship body.
[0077] More specifically, the second plate structure 2 can also be rotated clockwise by a first angle from the first position to a second position and fixed, and further rotated to a third position, a fourth position, and so on. Wherein, the first angle can be 10°, 18°, 30°, 45° or any other angle.
[0078] In some embodiments, the width of the portion of the second plate structure 2 located above the first plate structure 1 is smaller than the width of the first plate structure 2, so that it can be limited on the first plate structure 1 by a limiting mechanism, for example, limiting its rotation in a clockwise direction or limiting its rotation in a counterclockwise direction or both.
[0079] Furthermore, a row of fixing holes 12 is provided on each side of the first plate structure 1, and the width of the second plate structure 2 is configured such that the two rows of fixing holes 12 are exposed when rotated to the first position.
[0080] In one or more embodiments of this specification, the first plate-like structure 1 is further provided with a shaft groove 13 for receiving a portion of the lower end of the shaft 3. In some embodiments, the shaft groove 13 is a blind groove, and the bottom of the shaft groove 13 is provided with a threaded hole for fixing the shaft 3 with a threaded fastener. The shaft groove 13 guides and limits the shaft 3.
[0081] In one or more embodiments of this specification, the rotating shaft 3 includes an annular limiting boss 31 extending outward from its outer circumference. An accommodating space exists between the annular limiting boss 31 and the first plate-like structure 1. The annular limiting boss 31 provides a limiting surface facing the first plate-like structure 1. The second plate-like structure 2 includes a rotation limiting portion that matches the accommodating space, and the rotation limiting portion is configured to rotate around the rotating shaft 3.
[0082] See Figure 4 , Figure 5 In some embodiments, the rotating shaft 3 includes a cylindrical shaft structure 32 and an annular limiting boss 31 connected to the shaft structure 32. The rotating shaft groove 13 specifically guides and limits the lower end of the shaft structure 32.
[0083] The pivot hole 21 is a stepped hole, which includes a first stepped portion 211 and a second stepped portion 212. The inner diameter of the first stepped portion 211 is smaller than the inner diameter of the second stepped portion 212.
[0084] In some embodiments, the first step portion 211 is provided with a rotation limiting portion, and the inner wall of the first step portion 211 is disposed within the accommodating space.
[0085] The second step portion 212 accommodates the annular limiting boss 31. The arrangement of the second step portion 212 allows the upper surface of the rotating shaft 3 to be flush or substantially flush with the upper surface of the second plate structure 2, giving the second plate structure 2 a larger space for arranging equipment.
[0086] In some embodiments, the second plate structure 2 has side plates on both sides, and the device is connected to the side plates. In some further embodiments, the device may have a certain rotational relationship with the side plates, so the second plate structure 2 needs to provide a relatively flat surface.
[0087] In some embodiments of the present disclosure, when the rotating shaft 3 is fixed to the first plate structure 1, the annular limiting boss 31 is close to the first plate structure 1, and the lower surface of the annular structure 31 acts on the upper surface of the first step portion 211 of the second plate structure 2, so as to limit the second plate structure 2 between the annular limiting boss 31 and the first plate structure 1.
[0088] In some embodiments, the rotating shaft 3 and the first plate structure 1 are fastened by a plurality of threaded fasteners, and the gap between the annular limiting boss 31 and the first plate structure 1 is adjusted by adjusting the tightness of the threaded fasteners, so that the second plate structure 2 has a suitable space, i.e. the second plate structure 2 can rotate around the rotating shaft 3, but cannot swing relative to the first plate structure 1 in the vertical direction, so as to enhance the stability of the equipment carried by the second plate structure 2.
[0089] In some further embodiments, the second plate structure 2 is configured to have a larger contact surface with the first plate structure 1. In some embodiments, the rotating shaft 3 is configured to have an area of 1 / 4, 1 / 3 or more of the second plate structure 2, so as to provide better stability and mechanical properties.
[0090] Referring to FIG. 1, Figure 4 , Figure 5 In one or more embodiments of the present disclosure, a gasket is arranged between the second plate structure 2 and the first plate structure 1, and / or between the second plate structure 2 and the rotating shaft 3. In some embodiments, a gasket is arranged between the second plate structure 2 and the first plate structure 1. In other embodiments, a gasket is arranged between the second plate structure 2 and the rotating shaft 3. In other embodiments, a gasket is arranged between the second plate structure 2 and both.
[0091] Based on the strength consideration, in some embodiments, the first plate structure 1, the second plate structure 2 and the rotating shaft 3 are made of metal material, for example, specifically, an aluminum alloy material can be considered. Therefore, the second plate structure 2 is easy to generate dynamic friction with the first plate structure 1 and the rotating shaft 3 during rotation. In some embodiments, based on the strength, space and cost considerations, a bearing is usually not arranged between the second plate structure 2 and the rotating shaft 3, so the gasket is arranged as a friction interface and wear material, and after the gasket is worn out, the gasket can be replaced by disassembling the rotating shaft 3.
[0092] In some embodiments, the gasket is a nylon gasket.
[0093] Specifically, in some embodiments, the gasket includes a first gasket 41 arranged between the second plate structure 2 and the first plate structure 1.
[0094] The first gasket 41 is annular, and its cross-section is in the shape of an "I". The upper surface of the first gasket 41 faces the second plate structure 2, and the lower surface of the first gasket 41 faces the first plate structure 1.
[0095] Specifically, in some embodiments, the gasket includes a second gasket 42 disposed between the second plate-like structure 2 and the rotating shaft 3.
[0096] The second gasket 42 is annular and has an "L"-shaped cross-section. The second gasket 42 includes a horizontal portion 421 and a vertical portion 422 that are connected to each other. The horizontal portion 421 is arranged between the rotation limiting part and the limiting surface, and the vertical portion 422 is arranged between the rotation limiting part and the outer peripheral surface of the rotating shaft 3.
[0097] In one or more embodiments of this specification, the rotating base further includes: a first limiting member 5, the first limiting member 5 being disposed on one side of the first plate-shaped structure 1, the first limiting member 5 rotating around a first limiting member rotating shaft perpendicular to the rotating shaft 3; the first limiting member 5 having a first limiting portion, the first limiting portion being able to protrude from the first plate-shaped structure 1 after rotation.
[0098] Specifically, the first plate-like structure 1 has a first limiting member groove 14 for accommodating the first limiting member 5, and the first limiting member 5 is disposed in the first limiting member groove 14 by a pin or a rotating shaft. In some embodiments, the pin or rotating shaft is arranged parallel to the plane on which the first plate-like structure 1 is located, that is, it is perpendicular to the rotating shaft 3. The first limiting member 5 can rotate so that it is completely housed inside the first limiting member groove 14, or protrudes from the first limiting member groove 14.
[0099] When the first limiting member 5 is housed inside the first limiting member groove 14, the second plate-shaped structure 2 can rotate freely. When the first limiting member groove 5 protrudes from the first limiting member groove 14, the second plate-shaped structure 2 is blocked in a certain rotational direction.
[0100] by Figure 1 For reference, the first limiting member 5 is set at... Figure 1 On the upper side of the first plate-shaped structure 1, when the first limiting member 5 rotates to... Figure 1 When the position shown in the figure is reached, it obstructs the counterclockwise rotation of the second plate structure 2, preventing the second plate structure from continuing to rotate counterclockwise further from the first position.
[0101] In one or more embodiments of this specification, see Figure 12 As shown, the rotating base may not have a first limiting member, and the first limiting member groove may not be opened on the first plate structure 1, thereby allowing the second plate structure 2 to rotate in the circumferential direction.
[0102] In one or more embodiments of this specification, the rotating base further includes: a first fixing member, which passes through the first limiting portion and is detachably connected directly or indirectly to the second plate-shaped structure 2.
[0103] In some embodiments, a side plate is fixed to the second plate-like structure 2, and a first fixing member passes through the first limiting portion and is detachably connected to the side plate. The first fixing member fixes the position of the first limiting member, and in particular, the first fixing member keeps the first limiting member in a state protruding from the first plate-like structure 1.
[0104] In some embodiments, the first fastener is a bolt.
[0105] In some embodiments, the first fixing member is a spring pin, which includes a housing, a pin disposed within the housing, and elastic members at both ends abutting against the pin and the housing, respectively. Both ends of the pin protrude from the housing, and the pin is configured to move elastically relative to the housing along its axial direction. A first limiting member positioning hole is provided on the side or side plate of the second plate structure 2. The housing of the spring pin is fixed to the first fixing member, and the pin end of the spring pin is inserted into the first limiting member positioning hole. The elastic member causes the pin to always tend to face the first limiting member positioning hole on the side or side plate of the second plate structure 2.
[0106] In the embodiment of the spring pin, pulling out the spring pin allows the first limiting member 5 to rotate freely. On the other hand, when the first limiting member 5 rotates to a position directly opposite the positioning hole of the first limiting member, the spring pin can automatically insert into the positioning hole of the first limiting member to lock it in place.
[0107] In one or more embodiments of this specification, the rotating base further includes: a second limiting member disposed on the other side of the first plate-shaped structure 1; the second limiting member has a fixedly disposed second limiting portion protruding from the first plate-shaped structure 1. In some embodiments, the second limiting member is a screw or a pin.
