The present invention provides a far and offshore gravity sinking and floating mother ship power generation dock (as shown in Figure 1) including a mother ship 1, a mechanical power transmission device, a hydraulic power transmission mechanism and a generator set. The mechanical power transmission device includes a first transmission shaft 21 And a mechanical power transmission mechanism, on the left and right sides of the mother ship 1 are provided two groups of the mechanical power transmission mechanism distributed in sequence along the front and rear directions of the mother ship 1, each group of the mechanical power transmission mechanism includes a child The ship 22 and the transmission coordination mechanism, two groups of the transmission coordination mechanism are sequentially arranged on the corresponding sub-ship 22 along the front-rear direction of the mother ship 1, and each group of the transmission coordination mechanism includes a square drive frame 231, The first transmission gear 232 and the second transmission gear 233, the square drive frame 231 is vertically fixed on the sub-ship 22, and the two first transmission shafts 21 are respectively arranged on the sub-ship 22 through a plurality of first support frames 11 On the left and right sides of the mother ship 1, and the first transmission shaft 21 penetrates the corresponding square drive frame 231, the first transmission shaft 21 can freely rotate relative to the first support frame 11, and the first transmission shaft 21 On the shaft section corresponding to the square drive frame 231, a first one-way transmission member coaxial with the first transmission shaft 21 is provided, and the first transmission gear 232 and the second transmission gear 233 are sequentially arranged in the corresponding On the first one-way transmission member, the first transmission gear 232 and the second transmission gear 233 can only realize the rotation of the first transmission shaft 21 in the same direction through the one-way transmission of the first one-way transmission member. In the specific embodiments, two specific embodiments of the first one-way transmission member are designed. The specific implementation of the first embodiment of the first one-way transmission member is: the first one-way transmission member includes a first transmission Tube 211, the first transmission tube 211 and the first transmission shaft 21 can be directly connected together by welding or by spline transmission. A number of first pawls 2111 are provided on the first transmission tube 211, so The first transmission gear 232 and the second transmission gear 233 are sequentially sleeved on the corresponding first transmission tube 211, and the inner side walls of the first transmission gear 232 and the second transmission gear 233 are both provided with The first pawl groove 2321 matched with the first pawl 2111, the rotation of the first transmission gear 232 and the second transmission gear 233 in the same direction can pass through the lock of the first pawl 2111 and the first pawl groove 2321 The dead fit realizes the rotation of the first transmission shaft 21 in the same direction; the specific implementation of the second embodiment of the first one-way transmission member is: the first one-way transmission member includes two first one-way bearings, A transmission gear 232 and a second transmission gear 233 are correspondingly sleeved on the two first one-way bearings. The outer ring of the first one-way bearing and the corresponding first transmission gear 232 or the second transmission gear 233 The inner side wall is fixedly connected, and the inner ring of the first one-way bearing is fixedly connected to the first transmission shaft 21; the left side wall 2311 of the square drive frame 231 is provided with the first transmission gear 232 The first transmission rack 2313 of the square drive frame 231 is provided with a second transmission rack 2314 that cooperates with the second transmission gear 233 on the right side wall 2312 of the square drive frame 231, and the first transmission rack 2313 and the second transmission rack 2313 The two transmission racks 2314 are distributed in a staggered state in the square driving frame 231.

In this specific embodiment, the first specific embodiment of the first one-way transmission member is adopted for implementation. Specifically, the relative locking design of the first pawl 2111 and the first pawl groove 2321 is as follows: When a transmission shaft 21 is viewed from the front to the rear, when the first pawl groove 2321 rotates counterclockwise, the first pawl 2111 and the first pawl groove 2321 can be locked, so that the first transmission gear 232 or The second transmission gear 233 drives the first transmission shaft 21 to rotate. When the first pawl groove 2321 rotates clockwise, the first pawl 2111 and the first pawl groove 2321 can be unlocked, so that the first transmission gear 232 can be unlocked. Or the second transmission gear 233 cannot drive the first transmission shaft 21 to rotate. Specifically, when the first transmission rack 2313 descends (at this time, the second transmission rack 2314 also performs a descending movement), the first transmission rack 2313 drives The first transmission gear 232 rotates counterclockwise (at this time, the second transmission rack 2314 drives the second transmission gear 233 to rotate clockwise), and then realizes the counterclockwise rotation of the first transmission shaft 21, when the first transmission rack 2313 rises (At this time, the second transmission rack 2314 also moves up), the first transmission rack 2313 drives the first transmission gear 232 to rotate clockwise (At this time, the second transmission rack 2314 drives the second transmission gear 233 to rotate counterclockwise ), so that the first transmission gear 232 cannot drive the rotation of the first transmission shaft 21, but the second transmission gear 233 is driven to rotate counterclockwise through the second transmission rack 2314, and the counterclockwise rotation of the first transmission shaft 21 can also be realized. Thereby, it can be ensured that no matter when the square drive frame 231 is rising or falling, the first drive shaft 21 always rotates counterclockwise, and then the continuous operation of the first drive shaft 21 is realized; in practical applications, in order to stabilize the square drive frame 231 Here, the mother ship 1 is provided with a guide frame 14 for guiding the vertical movement of the square drive frame 231. Further, in order to improve the anti-sinking ability of the mother ship 1 and the daughter ship 22, here, the mother ship 1 There are multiple independent airtight cabins inside the Hezi ship 22. When one of the independent airtight chambers is destroyed, the remaining airtight chambers are still in a closed state, so that the mother ship 1 and the child ship 22 will not easily see water.

When the sub-ship 22 sinks, the sub-ship 22 drives the hydraulic cylinder The outer casing of 31 moves downwards. At this time, the rod cavity of the hydraulic cylinder 31 is squeezed. As the sub-ship 22 sinks, the hydraulic oil in the rod cavity of the hydraulic cylinder 31 is squeezed and passes through the two-position three-way The electromagnetic reversing valve 32 enters the hydraulic motor 34, and then realizes the rotation of the hydraulic motor 34; in storms and weather, the sub-ship 22 needs to be raised, and the process of raising the sub-ship 22 is: staff, give the controller a hydraulic pump 34 Start signal. After the controller receives the start signal of the hydraulic pump 34, it starts the two-position three-way electromagnetic reversing valve 32 and the hydraulic pump 34, so that the hydraulic pump 34 starts to flow into the rod cavity of the hydraulic cylinder 31 High-pressure oil is injected, and hydraulic oil is continuously injected as there is a rod cavity in the hydraulic cylinder 31, and then the outer casing of the hydraulic cylinder 31 is raised, thereby realizing the raising of the sub-ship 22.
