[0026] The following further describes the specific embodiments of the present invention:

[0027] See Figures 1 to 7 , this embodiment provides a floating ball deploying and retrieving device for the sea, which is used to quickly deploy and retrieve the floating ball 1 on the sea surface.

[0028] See Figure 1 and Figure 2 , the floating ball deploying and retrieving device of this embodiment includes a floating ball 1, a main pod 2, and a ball top plate 3.

[0029] See Figure 5 , the floating ball 1 is a device of the prior art. The floating ball 1 has a floating ball frame 11 as the main body, and numerous spherical floating bodies 12 are arranged on the circumferential part of the floating ball frame 11 to form a complete floating ball 1.

[0030] See Figure 4 , the ball top plate 3 is integrally in a cross-plate configuration and is assembled at the top of the floating ball 1.

[0031] See Figure 1 and Figure 2 , the ball top plate 3 is assembled at the top of the floating ball 1. The assembly method is that the edge part of the ball top plate 3 is in contact with the top of the spherical floating body 12 of the floating ball 1, and then four clamping members 4 are used to fixedly connect the edge part of the ball top plate 3 and the top of the spherical floating body 12 together, thus realizing the assembly of the two.

[0032] See Figure 6 , it should be noted that the clamping member 4 is a connecting component of the prior art, which is composed of two clamping plates and four bolt fasteners. A clamping hole is also provided between the two clamping plates to facilitate clamping the steel bar of the floating ball frame 11.

[0033] See Figure 1 and Figure 2 , a iron sheet 31 is provided at the central part of the ball top plate 3, and numerous guiding rods 5 are arranged around the iron sheet 31. These guiding rods 5 are inclined at a certain angle away from the iron sheet 31 around the iron sheet 31, and all the guiding rods 5 together form a configuration similar to a flared opening facing upward.

[0034] For the convenience of description, such an arrangement form is defined and named as the "downward import arrangement form", that is, all the import rods 5 are arranged in a downward import arrangement form around the iron sheet 31. Such an arrangement form is beneficial to import the main nacelle 2 to the iron sheet 31 at the center of the spherical top plate 3.

[0035] It should be noted that the import rod 5 is assembled on the spherical top plate 3 through an adjustable angle support 6 of an existing technology. In this way, the import rod 5 can adjust the angle based on the spherical top plate 3, so as to adjust the angles of the respective import rods 5, thereby forming the downward import arrangement form mentioned above.

[0036] See Figure 7 , the adjustable angle support 6 mainly includes a rod sleeve 61 and a base 62. The rod sleeve 61 and the base 62 are assembled together through a tightening bolt hinge mechanism 63 of an existing technology. When the bolt in the tightening bolt hinge mechanism 63 is loosened, the rod sleeve 61 and the base 62 are movable and can adjust the included angle between each other. When the bolt in the tightening bolt hinge mechanism 63 is tightened, the rod sleeve 61 and the base 62 are clamped, and the included angle between each other is fixed. The base 62 of the adjustable angle support 6 is fixedly connected to the spherical top plate 3. When installing the import rod 5, the lower end of the import rod 5 is assembled with the rod sleeve 61.

[0037] See Figure 3 , an electromagnet 21 is provided at the bottom of the main nacelle 2, and the electromagnet 21 is used to adsorb the iron sheet 31 at the center of the spherical top plate 3. A camera 22 is provided beside the main nacelle 2, and the lens of the camera 22 faces the electromagnet 21. The camera 22 is used to observe "whether the electromagnet 21 adsorbs or detaches from the iron sheet 31 at the center of the spherical top plate 3".

[0038] A lifting ring 23 is provided at the top of the main nacelle 2 to facilitate the lifting of the main nacelle 2 by using a lifting device.

[0039] An electric control unit is provided inside the main nacelle 2, and the electric control unit is used to control the switch start and stop of the electromagnet 21 and control the camera 22 to collect videos.

[0040] In addition, a wireless data transmission component (a radio for integrated graphic and data transmission) is configured for the electric control unit. In this way, the electric control unit can realize wireless communication with a pre-prepared remote control terminal (a remote controller for integrated graphic and data transmission) through the wireless data transmission component. On the one hand, the switch start and stop of the electromagnet 21 can be remotely controlled through the remote control terminal. On the other hand, the video collected by the camera 22 can be obtained through the remote control terminal, and the situation of the electromagnet 21 adsorbing the iron sheet 31 can be observed in real time.

[0041] The usage method and working principle of the offshore floating ball deployment and recovery device of this embodiment are as follows:

[0042] When the floating ball 1 needs to be placed on the sea surface, on the mother ship, the electromagnet 21 of the main nacelle 2 is attached to the iron sheet 31 of the ball top plate 3. The electromagnet 21 is controlled to be turned on through the remote control terminal. The electromagnet 21 is adsorbed to the iron sheet 31, and the main nacelle 2 and the floating ball 1 are combined into one. The hoisting equipment (winch) on the mother ship is used to hoist the main nacelle 2 to the sea surface through the sling 23. The combination of the main nacelle 2 and the floating ball 1 floats on the sea surface. Then, the electromagnet 21 is controlled to be turned off again through the remote control terminal, and the electromagnet 21 is separated from the iron sheet 31, that is, the main nacelle 2 is separated from the floating ball 1, thus completing the placement of the floating ball 1 on the sea surface.

[0043] When the floating ball 1 on the sea surface needs to be recovered to the mother ship, the hoisting equipment (winch) on the mother ship is used to hoist the main nacelle 2 to the position of the floating ball 1 floating on the sea surface through the sling 23. The hoisting equipment is controlled to align the main nacelle 2 with the floating ball 1 below and slowly lower it towards the iron sheet 31 at the center of the ball top plate 3. When the main nacelle 2 approaches the iron sheet 31, under the guiding action of the numerous guiding rods 5, the main nacelle 2 is guided to the iron sheet 31 at the center of the ball top plate 3 until the electromagnet 21 at the bottom of the main nacelle 2 is seated on the iron sheet 31. The video image collected by the observation camera 22 is used to judge whether the electromagnet 21 is seated firmly on the iron sheet 31. After determining that the electromagnet 21 is seated firmly, on the mother ship, the electromagnet 21 is controlled to be turned on through the remote control terminal. The electromagnet 21 is adsorbed to the iron sheet 31, and the main nacelle 2 and the floating ball 1 are combined into one. Then, the hoisting equipment is controlled to hoist the combination of the main nacelle 2 and the floating ball 1 back to the mother ship, thus completing the entire recovery process.

[0044] With the sea floating ball placement and recovery device of this embodiment, the floating ball 1 can be conveniently and quickly placed on the sea surface or recovered from the sea surface.

[0045] In addition, the sea floating ball placement and recovery device also has the following advantages:

[0046] 1) In the sea floating ball placement and recovery device of this embodiment, the guiding rods 5 arranged around the iron sheet 31 are arranged in a downward guiding layout. In this way, the combination of these guiding rods 5 has a guiding effect. During the process of recovering the floating ball 1, the main nacelle 2 can be guided to the position of the iron sheet 31, so that the precise docking of the electromagnet 21 and the iron sheet 31 can be quickly realized;

[0047] 2) In the sea floating ball placement and recovery device of this embodiment, the camera 22 can transmit the moving image of the floating ball 1 below the main nacelle 2 in real time, assisting the construction personnel to quickly judge whether the main nacelle 2 can be smoothly guided through the guiding rods 5 to the iron sheet 31 to complete the docking, and in the case of being unable to complete the docking smoothly, adjusting in time for a second docking attempt;

[0048] 3) In the offshore buoy deployment and recovery device of this embodiment, the mechanical structure is highly simplified, significantly reducing the component complexity and failure rate, and having high working reliability under high-grade sea conditions.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
