DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-9 , the present invention provides a technical solution: a wave energy conversion floating power generation device, including a device base 1, a chain 2 is fixed to the lower side of the device base 1, a wire 3 is wound around the chain 2, and a weight 4 is fixed to the lower end of the chain 2.

[0030] Furthermore, both the chain 2 and the weight 4 are made of stainless steel to ensure the long-term stable working state of the device in seawater.

[0031] A limiting rod 5 and a fixing rod 6 are installed on the upper side of the device base 1. The upper ends of the limiting rod 5 and the fixing rod 6 are connected to a top seat 9. A warning light 10 is installed on the top seat 9. A connecting seat 7 is installed on the outer side of the fixing rod 6, and a floating body 8 is fixed to the outer side of the connecting seat 7.

[0032] Furthermore, two groups of the limiting rod 5 and the fixing rod 6 are symmetrically arranged about the centers of the device base 1 and the top seat 9 to ensure the uniform overall structure of the device, and thus ensure the stable floating state. Both ends of the limiting rod 5 and the fixing rod 6 are threadedly connected to the device base 1 and the top seat 9, which is convenient for the disassembly and assembly of the limiting rod 5 and the fixing rod 6 of the device, and thus convenient for the maintenance of the device.

[0033] Furthermore, the connection part between the connecting seat 7 and the fixing rod 6 is in a "U" shape, and the size matches that of the fixing rod 6 to ensure the stable connection state between the connecting seat 7 and the fixing rod 6. And the connecting seat 7 and the fixing rod 6 are fixed by bolts, which is convenient for the disassembly and assembly of the connecting seat 7, and thus convenient for the replacement of the floating body 8 to ensure the long-term working state of the device.

[0034] A screw rod 17 is installed between the top seat 9 and the device base 1 through a bearing. A pressing and rotating seat 11 is arranged on the screw rod 17. The first spring 14 and the second spring 15 are respectively fixed to the upper and lower sides of the pressing and rotating seat 11. A pressing and rotating assembly for driving the screw rod 17 to rotate is arranged between the pressing and rotating seat 11 and the screw rod 17. Floating block connecting rods 12 are fixed to both sides of the pressing and rotating seat 11, and floating blocks 13 are fixed to the outer ends of the floating block connecting rods 12. The lower end of the screw rod 17 is connected to a permanent magnet generator 25. The permanent magnet generator 25 is installed in the device base 1, and the permanent magnet generator 25 is electrically connected to the wire 3.

[0035] Furthermore, pulleys 16 are installed on both sides of the pressing and rotating seat 11, and the outer side of the pulley 16 is connected to a limit rod 5, which is embedded in the pulley 16, which not only ensures the stable working state of the pressing and rotating seat 11, but also facilitates the up and down displacement of the pressing and rotating seat 11.

[0036] Furthermore, the fixing rod 6 does not contact the pressing and rotating seat 11 , so as to avoid affecting the up and down displacement of the pressing and rotating seat 11 .

[0037] Furthermore, the pressing and rotating assembly includes a screw rod connecting block 18, a bearing 19, an upper ratchet tooth 20, a movable connecting tube 21, a fixed connecting tube 22, a third spring 23 and a lower ratchet tooth 24. The screw rod connecting block 18 is connected to the screw rod 17. The screw rod connecting block 18 is installed in the pressing and rotating seat 11 through the bearing 19 to ensure that the screw rod connecting block 18 can rotate in the pressing and rotating seat 11. The lower side of the screw rod connecting block 18 is provided with an upper ratchet tooth 20, and the lower side of the upper ratchet tooth 20 is connected to the lower ratchet tooth 24. The lower ratchet teeth 24 are arranged on the movable connecting tube 21. Through the connection between the upper ratchet teeth 20 and the lower ratchet teeth 24, the rotation of the spiral rod connecting block 18 can be limited. The movable connecting tube 21 is sleeved on the outside of the fixed connecting tube 22, and the fixed connecting tube 22 is fixed in the pressing and rotating seat 11. A third spring 23 is arranged in the fixed connecting tube 22. The upper end of the third spring 23 is connected to the inner side of the movable connecting tube 21, and the lower end of the third spring 23 is connected to the inner side of the pressing and rotating seat 11, so that the movable connecting tube 21 can move up and down through the third spring 23.

[0038] Furthermore, the screw rod connecting block 18 forms a rotating structure in the pressing and rotating seat 11 through the bearing 19 , and the pressing and rotating seat 11 and the screw rod 17 are always not in contact with each other, so as to avoid affecting the rotation of the screw rod 17 .

[0039] Furthermore, a protruding structure is provided on the outer side of the fixed connecting cylinder 22, and the movable connecting cylinder 21 can only move up and down but cannot rotate on the outer side of the fixed connecting cylinder 22 through the protruding structure. In this way, the limiting effect between the upper and lower ratchet teeth 24 of the movable connecting cylinder 21 and the upper ratchet teeth 20 on the spiral rod connecting block 18 can be achieved by limiting the movable connecting cylinder 21.

[0040] Working principle of this embodiment: When using the power generation device, firstly, the device needs to be placed in a suitable working position in the sea area, the weight 4 sinks to the seabed, the weight 4 fixes the device on the sea surface through the chain 2, and a buoy 8 is provided on the device to ensure the stable floating effect of the device. At the same time, the power generation device is connected to the external power storage equipment through the wire 3 to ensure normal power generation;

[0041] When the device is stably in the working position at sea, with the ups and downs of the waves, the chain 2, the weight 4 and the floating body 8 cooperate to ensure that the device is in a stable working state and can perform normal power generation. At the same time, after the device has been working for a long time, if the floating body 8 is damaged, the floating body 8 can be directly removed through the connecting seat 7 and replaced with a new one to ensure the long-term normal working state of the device;

[0042] Then the undulating waves will drive the floating block 13 to float up and down, and the floating block 13 will drive the pressing and rotating seat 11 to float up through the floating block connecting rod 12, and the side of the pressing and rotating seat 11 is connected to the limit rod 5 through the pulley 16 to ensure that the pressing and rotating seat 11 is in a stable upward state on the device;

[0043] When the pressing and rotating seat 11 moves upward, the screw rod connecting block 18 moves upward with it, and at the same time, the upper ratchet teeth 20 on the lower side of the screw rod connecting block 18 and the upper and lower ratchet teeth 24 of the movable connecting cylinder 21 engage with each other. When the movable connecting cylinder 21 is limited by the fixed connecting cylinder 22 and does not rotate, the screw rod connecting block 18 will not rotate either. Therefore, when the screw rod connecting block 18 does not rotate and moves upward, the screw rod 17 connected thereto will rotate accordingly, thereby driving the permanent magnet generator 25 in the device base 1 to generate electricity, and the generated electricity is transmitted to the power storage device through the wire 3;

[0044] When the floating block 13 moves downward with the waves, it drives the pressure rotating seat 11 to move downward, so that the spiral rod connecting block 18 moves downward. At this time, the spiral rod connecting block 18 rotates in the opposite direction through the spiral rod 17, and the reverse rotation of the upper ratchet teeth 20 will not engage with the lower ratchet teeth 24, so that the movable connecting cylinder 21 moves downward on the fixed connecting cylinder 22. At the same time, the movable connecting cylinder 21 moves upward and resets through the third spring 23, so that the spiral rod connecting block 18 can rotate in the opposite direction, so that the pressure rotating seat 11 moves downward quickly with the waves, so as to ensure that the subsequent wave power generation work is carried out normally;

[0045] Therefore, when the pressure rotary seat 11 moves upward with the waves, the screw rod connecting block 18 drives the screw rod 17 to rotate to generate electricity. When the pressure rotary seat 11 moves downward with the waves, the screw rod connecting block 18 can move downward quickly on the screw rod 17 to ensure that it can move up and down synchronously with the waves, thereby ensuring the high efficiency of power generation.

[0046] When the pressure rotary seat 11 rises and falls with the waves, the first spring 14 and the second spring 15 are provided on the upper and lower sides of the pressure rotary seat 11 to maintain the safety of the pressure rotary seat 11 moving up and down. If the pressure rotary seat 11 cannot move down in time when the waves sink, it will affect the power generation work when the waves float up next time. Therefore, when the pressure rotary seat 11 floats up at a relatively high position, the first spring 14 will be strongly squeezed. After the waves pass, its rebound force can make the pressure rotary seat 11 move down quickly, so that the subsequent waves can normally bring the pressure rotary seat 11 up, ensuring the normal and efficient power generation work;

[0047] The above is the working process of the power generation device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
