Description

Technical Field

[0001] This utility model relates to the field of sensor structure technology, and in particular to a protective cover for a wave energy self-powered sensor for marine buoys. Background Technology

[0002] A self-powered wave energy sensor is an intelligent monitoring device that integrates wave energy capture, conversion, and storage functions, enabling it to continuously power its own sensing module. It does not rely on an external power source and can operate autonomously in the marine environment for extended periods, making it a key technological equipment in fields such as marine monitoring and marine engineering.

[0003] The sensor is protected by a protective cover to resist seawater corrosion and improve its service life. However, in actual use, it has been found that the existing protective cover only serves as the outer layer of the sensor and lacks sufficient overall hydrodynamic stability. Under the action of seawater waves, the protective cover is prone to irregular shaking or rotation, which will lead to distortion of measurement data. In addition, there are many marine organisms in the ocean, which have a certain probability of covering the surface of the protective cover, accelerating material corrosion and seriously affecting the stability and efficiency of wave energy self-powered sensors. Therefore, we propose a protective cover for wave energy self-powered sensors for marine buoys. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] This utility model provides a protective cover for a self-powered wave energy sensor for marine buoys, which can solve the problem of protective covers capsizing on the ocean. The specific solution is as follows:

[0006] A protective cover for a wave-powered self-powered sensor for marine buoys includes a protective cover body. Several sets of buffer layers are uniformly installed on the surface of the protective cover body. An inner layer is fixedly connected inside the protective cover body. A support component is provided inside the inner layer. A sealing plate is threadedly connected to the end of the protective cover body. Fish fins are fixedly connected to both sides of the end of the sealing plate. The fish fins are evenly distributed on both sides of the edge of the protective cover body. Blades are movably connected to the top wall of the fish fins.

[0007] As a preferred technical solution of this utility model, the top wall of the fish fin is provided with a groove, the bottom plate is fixedly connected inside the fish fin, a drive guide rail is fixedly installed at the top of the bottom plate, a movable bar is connected in the middle of the drive guide rail, and a plurality of mating screw holes are preset on the top wall of the movable bar.

[0008] As a preferred embodiment of this utility model, a connecting rod is fixedly installed on the top of the movable strip through a screw hole, the top end of the connecting rod is fixed to the bottom end of the blade, and the blade is made of titanium alloy.

[0009] As a preferred embodiment of the present invention, the supporting component includes a first fixing ring and a second fixing ring, which are respectively installed in the middle of the inner layer and are arranged opposite to each other.

[0010] As a preferred embodiment of this utility model, connecting rods are fixedly installed at the four corners of the edges of the first and second fixing rings, and a fixing rod is fixedly installed between the two opposite connecting rods. The ends of the connecting rods are connected to the inner wall of the inner layer.

[0011] As a preferred technical solution of this utility model, the inner side of the sealing plate is fixedly connected to a threaded column, the threaded column is connected to the end of the protective cover, and an O-ring is preset between the threaded column and the protective cover.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0013] By adding two sets of fish fins to the sealing plate at the end of the protective cover, the limitation of a single set of fish fins being effective in one direction but ineffective in the opposite direction is avoided. When the water flow impacts from the left, the left fish fin disperses the impact force by guiding the flow, while the right fish fin simultaneously reduces the turbulence at the tail by suppressing the vortex. When the water flow impacts from the right, the opposite is true. The symmetrical fish fins can reduce the tilt of the protective cover by balancing the water flow forces on both sides.

[0014] A blade is installed on the top wall of the fin. This blade moves laterally with the internal transmission guide rail, which can cut off the marine organisms attached to the surface of the fin and make them fall off. This prevents a large number of marine organisms from adhering to the surface of the fin or the protective cover, thus increasing the service life of the protective cover and improving the stability of the internal sensors.

[0015] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0024] See Figures 1-4 This invention provides a protective cover for a wave-powered self-powered sensor for marine buoys, comprising a protective cover body 1, several sets of buffer layers 2 evenly installed on the surface of the protective cover body 1, an inner layer 3 fixedly connected inside the protective cover body 1, a support component inside the inner layer 3, a sealing plate 5 threadedly connected to the end of the protective cover body 1, and fish fins 6 fixedly connected to both sides of the end of the sealing plate 5. The fish fins 6 are evenly distributed on both sides of the edge of the protective cover body 1, and a blade 15 is movably connected to the top wall of the fish fins 6. The fish fin structure on the side wall can generate a stable torque through interaction with the water flow. The fish fins 6 arranged oppositely can cope with multi-directional water flow / waves, avoiding the limitation of a single set of fish fins being "effective in one direction and ineffective in the opposite direction". When the water flow impacts from the left, the fish fin 6 on the left disperses the impact force by guiding the flow, while the fish fin 6 on the right simultaneously reduces the tail turbulence by suppressing the eddy current; the opposite is true when the water flow impacts from the right. The symmetrical fish fins 6 can reduce the tilt of the protective cover by balancing the water flow forces on both sides.

[0025] The top wall of the fish fin 6 is provided with a slot 13, and the bottom plate 11 is fixedly connected inside the fish fin 6. The top of the bottom plate 11 is fixedly installed with a drive rail 12, and the middle of the drive rail 12 is connected to a movable bar 14. Multiple docking screw holes are pre-set on the top wall of the movable bar 14.

[0026] A connecting rod 16 is fixedly installed on the top of the movable strip 14 through a screw hole. The top of the connecting rod 16 is fixed to the bottom of the blade 15. The blade 15 is made of titanium alloy. A horizontally sliding blade 15 is set on the top wall of the fin 6. Its core function is to remove marine organisms attached to the protective cover and the surface of the fin 6 by physical means. The horizontally sliding blade 15 removes the attached organisms by pure physical cutting, without the release of chemical substances. The toxicity risk to the marine water and organisms is almost zero, which can protect the survival safety of surrounding organisms. The periodic sliding of the blade 15 can keep the attached organisms in a thin and small state. The amount of debris generated during removal is small and dispersed, which can be quickly decomposed by decomposers in the ocean, reducing the physical or ecological disturbance to other organisms. By maintaining the normal operation of the protective cover, the blade 15 indirectly reduces the physical and chemical threats to marine organisms caused by equipment failure, and ensures the stability of their living environment.

[0027] The support components include a first fixing ring 7 and a second fixing ring 10, which are respectively installed in the middle of the inner layer 3 and are arranged opposite to each other.

[0028] Connecting rods 9 are fixedly installed at the four corners of the edges of fixing ring 1 7 and fixing ring 2 10. A fixing rod 8 is fixedly installed between the two opposite connecting rods 9. The ends of the connecting rods 9 are connected to the inner wall of the inner layer 3. Fixing ring 1 7 and fixing ring 2 10 form a rigid fixation from different axes of the sensor, which is equivalent to providing two support points for the sensor at the front and back / up and down. This avoids the cantilever effect when fixed at a single point. It can provide a high-precision and high-stability installation foundation for the sensor, ensuring that its measurement accuracy is not affected by external interference. It can also be compatible with sensors of different specifications, simplifying the installation and maintenance process. It is an efficient solution for fixing sensors inside the protective cover, especially suitable for scenarios with high requirements for sensor stability, such as marine, industrial, and environmental monitoring.

[0029] A threaded post 4 is fixedly connected to the inner side of the sealing plate 5. The threaded post 4 is connected to the end of the protective cover 1, and an O-ring is pre-installed between the threaded post 4 and the protective cover 1. The O-ring is made of an oil-resistant and chemically corrosion-resistant elastic material. When compressed between the contact surfaces of the sealing plate 5 and the protective cover 1, it generates radial elastic force, tightly fitting the microscopic gaps between the two contact surfaces to form an elastic barrier. Experimental data shows that a qualified O-ring, when correctly installed, can achieve an IP68 level seal. During use, the sealing plate 5 can be installed and removed simply by turning the threaded post 4, without damaging the protective cover 1 or the sealing structure. During the maintenance of marine sensors, divers or underwater robots can complete the entire process of disassembling the sealing plate 5, inspecting internal components, and reinstalling it within 10-15 minutes, while the maintenance time for welded seals may take several hours.
