[0002] Buoys are used to aid navigation in navigable waters day and night. One end of the buoy is tied to the bottom of the water, while the buoy floats on the surface. Its function is to mark shallow waterways or obstacles that endanger navigation safety. Navigation lights work by being installed on buoys. They emit lights of specified colors and flashing frequencies at night to achieve specified illumination angles and visibility distances. The batteries used in domestic navigation lights have problems such as the trouble of replacing them when the batteries are exhausted and the short maintenance cycle. The currently proposed integrated solar navigation lights will also be affected by the weather, especially the areas across the Yangtze River.

DETAILED DESCRIPTION

[0024] like Figure 1-4 As shown, this embodiment includes a housing 1 , an outer tube 2 , an inner tube 3 , a first spring 4 , a striking member 6 , a driving member 7 , an MSMA 8 , a coil 9 , a magnet 10 and a second spring 11 .

[0025] The shell 1 adopts a closed structure with a cavity, specifically, the shell 1 comprises a box-shaped body and a cover covering the opening of the body. The shell 1 is horizontally arranged on the buoy and sways with the waves.

[0026] In this embodiment, a partition is arranged in the middle of the shell 1 to divide the cavity in the shell 1 into an upper cavity 1a and a lower cavity 1b. Two long plates are arranged in the upper cavity 1a to divide it into three chambers, wherein the middle chamber is used to install various components.

[0027] The outer tube 2, the inner tube 3, the first spring 4, the impact member 6, the driving member 7, the MSMA 8, the coil 9, the magnet 10 and the second spring 11 are all arranged in the middle chamber. This structure of the intentionally suspended oscillation mechanism is equivalent to the height of the support point being too high, so that when the bottom of the support shakes, the supported object on the support point will shake more strongly to increase the oscillation amplitude and enhance the energy conversion effect.

[0028] The inner tube 3 is a closed structure, and the impact member 6 is arranged in the inner tube 3. It should be noted that the closed structure is not a completely sealed body. The inner tube 3 adopts a closed structure to prevent the impact member 6 from escaping from the inner tube 3, so a hole communicating with the outside can be set on the inner tube 3.

[0029] One end of the inner tube 3 extends from one end of the outer tube 2 into the outer tube 2, and the inner tube 3 and the outer tube 2 are clearance-matched so that the inner tube 3 can slide back and forth in the outer tube 2. The other end of the inner tube 3 is arranged outside the outer tube 2, and the other end of the inner tube 3 is also provided with an inner tube flange 3a, and the outer tube 2 is provided with an outer tube flange 2a, and the inner tube flange 3a and the outer tube flange 2a are connected by a first spring 4. In other embodiments, the outer tube flange 2a and the inner tube flange 3a may not be provided, but an outer tube protrusion and an inner tube protrusion are respectively provided on the side walls of the outer tube 2 and the inner tube 3, and the outer tube protrusion and the inner tube protrusion are connected by a first spring 4. The function of the first spring 4 is to pull the inner tube 3 to do a back and forth thrusting motion relative to the outer tube 2.

[0030] The impact member 6 is a solid sphere, the diameter of which is slightly smaller than the inner wall size of the inner tube 3 , so as to ensure that the sphere can roll back and forth in the inner tube 3 .

[0031] MSMA8, also known as magnetically controlled shape memory alloy, is a new type of intelligent material, mainly composed of Ni-Mn-Ga, which can realize the mutual conversion of magnetic, mechanical and electrical energy. MSMA8 not only has the characteristics of large deformation of shape memory alloy, but also has the characteristics of fast dynamic response speed of magnetostrictive material (Terfenol-D), and its deformation and electromagnetic conversion performance are superior to piezoelectric materials and magnetostrictive materials. This embodiment is based on the reverse effect of MSMA8, that is, under the condition of bias magnetic field, MSMA8 is deformed under the action of external force, the magnetization state changes, and the magnetic flux density changes. Based on Faraday's law of electromagnetic induction, the changing magnetic field generates induced current in coil 9, thereby realizing the conversion of mechanical energy into electrical energy.

[0032] In order to better fix the MSMA 8, the present embodiment further provides a protective cover 12 and a baffle 13. The protective cover 12 is sleeve-shaped, and the MSMA 8 is disposed in the protective cover 12, with one end of the protective cover 12 facing the driving member 7, and the other end of the protective cover 12 blocked by the baffle 13. The protective cover 12 is fixed in the middle chamber, and can protect and fix the MSMA 8. In other embodiments, the baffle 13 or both the protective cover 12 and the baffle 13 can also be fixed in the middle chamber.

[0033] In addition, the protective cover 12 can also play a role in fixing the coil 9, and the coil 9 can be directly wound on the side wall of the protective cover 12. Furthermore, a protective cover flange 12a can be provided at each end of the protective cover 12. Two magnets 10 are provided and both are columnar. The two magnets 10 are permanent magnets, and the two ends of the two magnets 10 are respectively fixed on the two protective cover flanges 12a. In other embodiments, the protective cover 12 may not be provided, but the MSMA 8, the coil 9 and the magnet 10 may be directly fixed in the housing 1.

[0034] The driving member 7 is arranged between the inner tube 3 and the MSMA 8. In this embodiment, the driving member 7 is arranged in a cylindrical shape and a driving member flange 7a is arranged in the middle. One end of the driving member 7 abuts against the other end of the inner tube 3, and the other end of the driving member 7 abuts against the MSMA 8. In this embodiment, a spacer 5 is also arranged between the driving member 7 and the MSMA 8 to protect the MSMA 8.

[0035] The two ends of the second spring 11 are connected to the driving member flange 7a and the protective sleeve flange 12a respectively. The function of the second spring 11 is to pull the driving member 7 to hit the MSMA 8 back and forth. In other embodiments, the driving member flange 7a may not be provided but a driving member protrusion may be provided, and the second spring 11 may be connected to the driving member protrusion to achieve the same effect.

[0036] In order to ensure the conversion of mechanical energy into electrical energy, and to make full use of the effect of the shell 1 undulating and swinging left and right under the action of waves, this embodiment is provided with two sets of outer tubes 2, inner tubes 3, first springs 4, sealing plates, impact members 6, drive members 7, MSMA 8, coils 9, magnets 10 and second springs 11, forming two sets of energy conversion mechanisms which are arranged oppositely in the middle chamber. The two sets are arranged oppositely to each other to achieve a left-right balance, increase the swing amplitude, and improve the conversion of mechanical energy into electrical energy.

[0037] This embodiment does not use a structure in which a ball directly hits the driver 7, but instead sets a structure of an inner tube 3, an outer tube 2 and a first spring 4. Under this structure, as long as the ball hits the inner tube 3 once, the first spring 4 can make the inner tube 3 swing back and forth under the action of the elastic restoring force, and then hit the driver 7 back and forth, greatly increasing the deformation frequency of the MSMA 8, increasing the frequency of magnetic flux change, and thus collecting more electrical energy. In addition, when the first spring 4 and the second spring 11 vibrate at the same frequency, this structure can also play another role, that is, after the inner tube 3 hits the driver 7, the first spring 4 pulls the inner tube 3 back, so that the second spring 11 is not subjected to or reduces the pressure of the inner tube 3 on it when rebounding, which minimizes the effect of the inner tube 3 on the second spring 11, so that the driver 7 can maintain the best vibration effect. Ultimately, the effect of converting vibration energy into electrical energy can be greatly improved.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
