[0043] It should be noted that when an element is referred to as "fixed to" or "provided on" another element, it can be directly on another element or there can be a middle element.

[0044] The technical scheme of the utility model will be further illustrated below by combining the drawings and through specific embodiments.

[0045] The embodiment provides an installation platform and a wind power boosting device to solve the low locking efficiency of a flip cover in the prior art, thereby causing the low efficiency of a wind power boosting rotor entering a working state.

[0046] As Figure 1As shown, the wind-assisted device comprises a mounting platform and a wind-assisted rotor. The mounting platform comprises a cover 1, a base 2 and a driving assembly. The base 2 is horizontally mounted on the deck of the ship, and the cover 1 is horizontally arranged on the upper end of the base 2. The wind-assisted rotor is in a cylindrical shape, and one end of the wind-assisted rotor along the length direction is mounted on the upper end of the cover 1. When the cover 1 is in a horizontal state, the wind-assisted rotor is in an upright state. The cover 1 has a rotating side and an opening and closing side arranged oppositely. The rotating side is rotatably mounted on the upper end of the base 2, so as to drive the opening and closing side to approach or move away from the base 2 by the driving assembly according to the sailing requirement of the ship. With the opening and closing side of the cover 1 moving away from the base 2, the upper end of the cover 1 will gradually change from a horizontal state to a vertical state. Since the length direction of the wind-assisted rotor is perpendicular to the upper end of the cover 1, the wind-assisted rotor will gradually change from an upright state to a laid state, and the wind-assisted rotor will not work in the laid state and enter an idle state. When the ship needs the wind-assisted rotor to provide assistance, the opening and closing side of the cover 1 is driven to approach the base 2 by the driving assembly. The upper end of the cover 1 gradually changes from a vertical state to a horizontal state. Since the length direction of the wind-assisted rotor is perpendicular to the upper end of the cover 1, the wind-assisted rotor will gradually change from a laid state to an upright state. The wind-assisted rotor can provide assistance to the ship in the upright state.

[0047] The driving assembly can be a hydraulic cylinder. The rod side of the hydraulic cylinder is rotatably connected to the opening and closing side of the cover 1, and the rodless side of the hydraulic cylinder is rotatably connected to the base 2. In other embodiments, other types of driving assemblies can also be used as long as they can drive the opening and closing side to approach or move away from the base 2, which will not be limited here.

[0048] As shown in the drawings, Figures 2-5 The opening and closing side protrudes downwardly with a positioning portion 11, and the base 2 is provided with a positioning groove 21. The positioning portion 11 and the positioning groove 21 are matched. This arrangement can facilitate the accurate and rapid positioning of the cover 1 and the base 2 after the wind-assisted rotor is erected, thereby improving the erection efficiency of the wind-assisted rotor.

[0049] Further, the mounting platform comprises a locking pin 3 and an elastic member 5. The bottom of the positioning groove 21 is provided with a through hole, and the locking pin 3 is slidably arranged in the through hole to selectively locate in a locking position and an unlocking position. The upper end of the locking pin 3 has a screw portion 31 and the lower end has a limiting portion 32. The limiting portion 32 is located outside the through hole and is limited to pass through the through hole. The lower end of the positioning portion 11 is provided with a fastening screw hole 111. When the locking pin 3 is located in the locking position, the screw portion 31 extends into the positioning groove 21 and can be matched with the fastening screw hole 111. The upper side of the limiting portion 32 abuts against the base 2. When the locking pin 3 is located in the unlocking position, the screw portion 31 exits the positioning groove 21.

[0050] Understandably, when the wind-assisted rotor is erected, the positioning portion 11 is inserted into the positioning groove 21, in order to ensure that the wind-assisted rotor will not sway or fall after being blown by the wind, it is necessary to lock the positioning portion 11 in the positioning groove 21. By sliding the locking pin 3 in the through hole for a certain distance, the screw rod portion 31 can enter the positioning groove 21 and be screwed into the fastening threaded hole 111, while the limiting portion 32 upper side abuts against the base 2, thereby locking the positioning portion 11 in the positioning groove 21, and further realizing the fixation of the flip cover 1 and the base 2, ensuring that the wind-assisted rotor remains stable after being erected. When the wind-assisted rotor is no longer needed to assist the ship, in order to save the space above the ship and avoid interference between other machinery above the ship and the wind-assisted rotor, the wind-assisted rotor needs to be laid down. By unscrewing the locking pin 3 in the opposite direction, the screw rod portion 31 will gradually exit the fastening threaded hole 111 and then exit the positioning groove 21. At this time, the positioning portion 11 is unlocked from the locking of the positioning pin in the positioning groove 21. The drive assembly drives the opening and closing side of the flip cover 1 to gradually move away from the base 2 until it is completely laid down.

[0051] Alternatively, the through hole includes coaxially communicated upper hole portion 22 and lower hole portion 23, the hole diameter of the upper hole portion 22 is larger than that of the lower hole portion 23, the elastic member 5 is sleeved on the outer periphery of the locking pin 3 and located in the upper hole portion 22, the locking pin 3 is provided with a limiting member 4, the upper end of the elastic member 5 selectively abuts against the limiting member 4, and the lower end of the elastic member 5 abuts against the hole bottom of the upper hole portion 22. Through the above arrangement, the difference in hole diameter between the upper hole portion 22 and the lower hole portion 23 can form a step between them for bearing the lower end of the elastic member 5, facilitating the installation of the elastic member 5, and also avoiding the elastic member 5 from coming out of the through hole, improving the safety of the installation platform. Since the wind-assisted rotor is large in size, the parts of the installation platform are also large, and the operator needs to exert a lot of effort when lifting and screwing the locking pin 3. By setting the elastic member 5 between the limiting member 4 on the locking pin 3 and the hole bottom of the upper hole portion 22, the elastic member 5 generates an upward elastic force on the locking pin 3, that is, the elastic member 5 makes the locking pin 3 have a tendency to remain or return to the locking position, so that the locking pin 3 is more easily slid upward until it comes into contact with the positioning portion 11 and then is screwed into the fastening threaded hole 111 to enter the locking position, thereby improving the efficiency of the locking pin 3 entering the locking position and reducing the difficulty of the locking pin 3 entering the locking position. Before the locking pin 3 enters the locking position, the self-weight of the locking pin 3 compresses the elastic member 5, and as the locking pin 3 is lifted upward, the elastic member 5 gradually relaxes until the screw rod portion 31 is screwed into the fastening threaded hole 111, at which time the elastic member 5 is completely relaxed and comes out of contact with the limiting member 4. In other embodiments, after the screw rod portion 31 is screwed into the fastening threaded hole 111, the elastic member 5 can also be arranged to be not completely relaxed, remaining in the state of abutting against the limiting member 4.

[0052] In other embodiments, the elastic member 5 can also not be sleeved on the outer periphery of the locking pin 3, but a plurality of elastic members 5 are distributed between the outer wall of the locking pin 3 and the inner wall of the through hole, and the upper end of the elastic member 5 selectively abuts against the lower end of the limiting part 4, and the lower end of the elastic member 5 abuts against the hole bottom of the upper hole part 22. As long as the elastic member 5 can make the locking pin 3 have a tendency to remain or return to the locking position, it is not limited here.

[0053] The limiting part 4 can be preferably a positioning ring or a positioning square piece. In other embodiments, the limiting part 4 can also be other shapes as long as it can limit the spring to the locking pin 3, and it is not limited here.

[0054] In order to facilitate the periodic replacement of the limiting part 4 and ensure the reliability of the limiting part 4, the inner wall of the limiting part 4 is optionally provided with an internal thread and is screwed to the screw rod part 31. When the limiting part 4 needs to be replaced, it can be screwed off from the locking pin 3. In addition, the threaded cooperation of the limiting part 4 and the screw rod part 31 can also adjust the position of the limiting part 4 on the locking pin 3, so as to facilitate the adjustment of the pre-tightening force of the elastic member 5 according to the needs, so that the locking pin 3 is always in a state easy to be lifted, thereby improving the locking efficiency.

[0055] In order to improve the fitting tightness of the positioning part 11 and the positioning groove 21, the hole bottom of the fastening threaded hole 111 is optionally provided with a tapered groove 112, and the top end of the locking pin 3 is provided with a tapered protrusion 33, which cooperates with the tapered groove 112 when the screw rod part 31 cooperates with the fastening threaded hole 111. When the locking pin 3 is in the locking position, the tapered protrusion 33 inserted into the tapered groove 112 can improve the fitting tightness of the positioning part 11 and the positioning groove 21, increase the contact area between the two, and thereby improve the fastening stability between the cover 1 and the base 2.

[0056] Optionally, the mounting platform further comprises a gasket 6 sleeved on the outer periphery of the locking pin 3, the upper end of the gasket 6 abutting against the lower end of the elastic member 5, the lower end of the gasket 6 abutting against the hole bottom of the upper hole part 22, and the hole diameter of the gasket 6 being consistent with the shaft diameter of the locking pin 3; the setting of the hole diameter limits the locking pin 3 when it slides up and down, avoiding horizontal swinging of the locking pin 3 when it slides, thereby improving the stability of the locking pin 3 when it slides up and down; at the same time, the gasket 6 provides stable support for the lower end of the elastic member 5, avoiding insufficient horizontal degree of the lower end of the elastic member 5 abutting against the hole bottom of the lower hole part 23, which causes the elastic member 5 to shake and displace when it is compressed and relaxed, thereby improving the stability when switching between locking and unlocking, and prolonging the service life of the mounting platform.

[0057] In addition, since the locking pin 3 is large in size, it is difficult for the staff to find a suitable force point when screwing it from the lower end. Alternatively, the installation platform further comprises a control rod 322 installed at the lower end of the locking pin 3 and extending radially outward along the locking pin 3. Through this arrangement, the operator can hold the control rod 322 to screw the locking pin 3, which reduces the difficulty of screwing and improves the switching efficiency of the locking and unlocking of the locking pin 3.

[0058] Specifically, the limiting portion 32 is provided with a mounting hole penetratingly opened in the horizontal direction, and the control rod 322 is installed in the mounting hole. This arrangement allows the control rod 322 to be detachably installed at the lower end of the locking pin 3, and when it is not necessary to switch the locking and unlocking positions of the locking pin 3, the control rod 322 can be detached and stored, thereby improving the space utilization of the ship.

[0059] Alternatively, the positioning portion 11 is in the shape of a prism or a circular truncated cone, and the small end of the positioning portion 11 faces the base 2, and the shape of the positioning groove 21 is matched with the shape of the positioning portion 11; by setting the prism or circular truncated cone-shaped positioning portion 11 and the positioning groove 21 with the same shape as the positioning portion 11, after they are matched, they have a large contact area and a certain matching taper, which improves the stability of the matching, and in addition, the small end of the positioning portion 11 facing the base 2 can convert the gravity of the flip cover 1 itself into a pushing force against the side wall of the positioning groove 21, further improving the matching stability of the positioning portion 11 and the positioning groove 21.

[0060] Of course, the positioning portion 11 can also have other shapes in other embodiments, as long as it can ensure a sufficient contact area and convert gravity into a pushing force against the side wall, which is not limited here.

[0061] Alternatively, the upper end of the through hole has a smaller diameter than the diameter of the bottom end of the positioning groove 21, and the lower end of the positioning portion 11 abuts against the groove bottom of the positioning groove 21. This arrangement allows the lower end of the positioning portion 11 to be effectively supported, thereby improving the matching reliability between the positioning portion 11 and the positioning groove 21.

[0062] Alternatively, the limiting portion 32 is provided with a reinforcing protrusion 321 at the upper end along the circumference thereof, and the reinforcing protrusion 321 abuts against the base 2 when the screw portion 31 is screwed into the fastening screw hole 111. This arrangement strengthens the structural strength of the upper end of the limiting portion 32 by means of the reinforcing protrusion 321, so that the upper end of the limiting portion 32 can withstand a larger torque when it abuts against the base 2, thereby prolonging the service life of the limiting portion 32.

[0063] It should be noted that the above only the preferred embodiments of the present application and the use of technical principles. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, those skilled in the art can make various obvious changes, re-adjustment and replacement without departing from the scope of the present application. Therefore, although the above embodiments of the present application has been described in more detail, but the present application is not limited to the above examples, without departing from the concept of the present application, but also can include more other equivalent embodiments, and the scope of the present application is determined by the appended claims.
