Description

Technical Field

[0001] This invention relates to the field of tidal current power generation devices, and particularly to an oscillating tidal current power generation device. Background Technology

[0002] Tidal energy is the kinetic energy generated when the tidal forces of the moon and the sun cause the seawater to move in a periodic, reciprocating horizontal motion. It is mainly concentrated in waterways or bay mouths between shores and islands. However, existing tidal generators are not convenient for regular maintenance or replacement and still require dismantling by diving into the seabed. Summary of the Invention

[0003] The purpose of this invention is to provide a swing-type tidal energy generation device, which can facilitate the automatic floating of the power generation device and reduce the workload of maintenance personnel.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A swing-type tidal energy generation device includes a fixed base, on which a power generation component is detachably connected. The bottom of the power generation component is provided with several telescopic blocks, and the fixed base is provided with positioning holes for the telescopic blocks to be inserted. The power generation component includes a swing arm that swings back and forth to generate electricity, and several floats are connected to the top of the swing arm.

[0006] Furthermore, the top of the fixed base is provided with a mounting groove, the power generation component is inserted downward into the mounting groove, and the positioning hole is opened on the side of the mounting groove.

[0007] Furthermore, the float is detachably connected to the top of the swing arm.

[0008] Furthermore, the top of the swing arm is connected to a mounting frame, on which several floats are mounted, and the floats are connected to the mounting frame by several connecting ropes.

[0009] Furthermore, the mounting bracket is provided with several insert blocks, and the bottom of the float is inserted into the insert blocks.

[0010] Furthermore, the connecting rope breaks after exceeding the set load, and the float is also connected to a recovery chain, the bottom of which is fixed to a fixed point on the seabed.

[0011] Furthermore, the seabed fixing point is located on one or both sides of the fixing base, and is coaxial with or above and below the swing axis of the power generation component.

[0012] Furthermore, the outer end of the positioning hole is tilted downwards.

[0013] Furthermore, the bottom of the mounting groove is provided with several equal-height blocks, and the power generation component abuts against the equal-height blocks.

[0014] In summary, the present invention has the following beneficial effects:

[0015] The float provides an upward force, allowing the swing arm to return to its original position when swinging left and right. It works in conjunction with the telescopic block to fix the bottom of the generator. The generator can be periodically or remotely detached from the fixed base, facilitating the periodic maintenance or replacement of the generator. The float is fixed to the mounting frame by a connecting rope. In harsh environments, it can detach when the load of the connecting rope is exceeded, allowing the swing arm to be lowered to avoid severe weather. Attached Figure Description

[0017] Figure 2 This is a schematic diagram of the power generation component in this invention.

[0018] In the diagram, 1 is the fixed base; 11 is the mounting slot; 12 is the leveling block; 2 is the generator; 21 is the telescopic block; 22 is the swing arm; 23 is the mounting frame; 3 is the float; and 31 is the connecting rope. Detailed Implementation

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation on the present invention.

[0020] A swing-type tidal current power generation device, such as Figure 1 As shown, it includes a fixed base 1, on which a generator 2 is detachably connected. The generator 2 includes a C-shaped swing block that reciprocates to generate electricity. An installation cylinder is integrally connected to the outside of the C-shaped swing block. A swing arm 22 is detachably connected to the installation cylinder by screws. Several floats 3 are connected to the top of the swing arm 22. The floats 3 provide an upward pulling force to the upper end of the swing arm 22, so that the swing arm 22 can return to its upward position when it swings under the action of the current. The swing-type generator is existing technology. For example, hydraulic power generation is achieved by driving the extension and retraction of a hydraulic cylinder during swing. It will not be described in detail here.

[0021] like Figure 1 As shown, in order to facilitate the periodic or remote detachment of the generator 2 and its upward movement under the action of the float 3, several telescopic blocks 21 are provided at the bottom of the generator 2. The telescopic blocks 21 are driven to extend and retract by hydraulic or electric cylinders inside the generator 2. The fixed base 1 is provided with positioning holes for the telescopic blocks 21 to be inserted.

[0022] Specifically, the top of the fixed base 1 has a mounting groove 11, the generator 2 is inserted downward into the mounting groove 11, and the positioning hole is opened on the side of the mounting groove 11; and several level blocks 12 are provided at the bottom of the mounting groove 11, the generator 2 abuts against the level blocks 12 to prevent sand and other debris from accumulating and preventing the generator 2 from being installed in the fixed base; the outer end of the positioning hole is inclined downward to prevent sand and other debris from entering the positioning hole and preventing the telescopic block 21 from being inserted.

[0023] like Figure 2 As shown, the float 3 is detachably connected to the top of the swing arm 22; specifically, the top of the swing arm 22 is fixedly connected to the mounting frame 23, which is a truss structure, with several mounting plates fixed on it, and several plugs fixed on the mounting plates. The bottom of the float 3 is fixed with a corresponding socket and plugged into the plug.

[0024] The float 3 is connected to the mounting frame 23 by several connecting ropes 31 to position and fix the position of the float 3. The connecting ropes 31 are selected with a set load to ensure that in extreme weather conditions, the connecting ropes 31 will break after exceeding the set load, causing the float 3 to detach. The swing arm 22 lies flat on the seabed under its own weight, avoiding damage to the generator 2. In shallow sea areas where the buoyancy is small, the fixed base 1 can also be directly equipped with an active drive device to drive the swing arm 22 to rotate, so as to directly drive the swing arm to lie flat, instead of achieving this through the passive breakage of the connecting ropes 31.

[0025] To facilitate the recovery of the disconnected float 3, a recovery chain is also connected to the float 3. The bottom of the recovery chain is fixed to a fixed point on the seabed. The fixed point on the seabed is located on one or both sides of the fixed base 1 and is coaxial with or above and below the swing axis of the generator 2, so as to facilitate daily swinging.

[0026] Working principle:

[0027] During installation, the bottom of the generator 2 is positioned by the mounting slot 11. Once in place, the telescopic block 21 is extended to fix the position of the generator 2. Then, the swing arm 22 swings under the drive of the current. The telescopic block 21 is retracted periodically or remotely, so that the generator 2 floats up under the action of buoyancy, which is convenient for maintenance and replacement. In case of extreme weather, the connecting rope 31 is disconnected after exceeding the load, so that the swing arm 22 lies flat on the seabed under its own weight, reducing damage, and waiting for the replacement of the float 3 (completed by replacing the entire mounting frame 23).

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
