Description

Technical Field

[0001] The present invention relates to the technical field of marine environment monitoring, and specifically to a marine environment monitoring device. Background Art

[0002] Marine environmental parameters include: air temperature, humidity, air pressure, rainfall, clouds, fog, wind field, etc. in the atmospheric environment; temperature, salinity, pressure, ocean current, water color, etc. in the water environment; terrain, landform, etc. on the seabed. Marine environmental parameter sensing technology is the technology for acquiring, transmitting, and storing marine environmental parameters, mainly including satellite observation technology, scientific research ship observation technology, shore-based and submersible / floating buoy observation technology, mobile platform observation technology, and seabed observation network technology, etc. Due to the cross-disciplinary characteristics, marine science poses high requirements for the comprehensiveness of observation means and platforms, and it is necessary to develop new integrated marine observation technologies characterized by low power consumption, high precision, low drift, and multi-sensors, and to break through key technologies in many aspects such as large-flow, all-weather, full-sea-depth, safe and reliable real-time transmission, underwater real-time communication, collaborative observation of sensors, and energy supply.

[0003] A kind of split floating body light buoy for sea route disclosed in the prior art (KR102270399B1), this invention includes a tower-shaped structure; a central frame connected to the lower part of the tower structure; a plurality of separate unit buoyancy bodies providing buoyancy for the tower structure; and a coupling member configured to couple the central frame to at least one of the plurality of unit buoyancy bodies. The central frame includes a vertical body and a coupling plate extending outward from the vertical body. Moreover, this unit floating body includes a buoyancy providing part in which a hollow part is formed, and a connection part formed at the side end of the buoyancy providing part to insert the coupling member. Although this invention provides a detachable and easy-to-install buoy, for this type of non-integrally formed buoy in actual use, it lacks the ability to resist wind and waves and slow down the occurrence of mechanical fatigue of the connecting parts. Summary of the Invention

[0004] The purpose of the present invention is to provide a marine environment monitoring device to solve the problems that the existing devices cannot effectively resist sea wind and waves, slow down the occurrence of mechanical fatigue, reduce the probability of damage to internal components of the device, and enhance the overall connection stability of the device.

[0005] To achieve the above object, the present invention provides the following technical solutions: A marine environment monitoring device, comprising: a buoy body having a hollow cylindrical structure; a buoyancy strengthening member fixedly connected to the lower part of the buoy body; a counterweight body having a solid cylindrical structure, the counterweight body being fixedly connected to the lower part of the buoyancy strengthening member; an anchor plate fixedly connected to the lower part of the counterweight body; a movable floating ring coaxially sleeved on the counterweight body, the movable floating ring having an annular structure, and 4 buffer grooves are circumferentially and equidistantly arranged on the outer side wall of the counterweight body, buffer assemblies are respectively arranged in the buffer grooves, the outer wall surface of the buffer assembly fits the inner wall surface of the buffer groove, a pulley assembly is fixedly connected to the inner ring surface of the movable floating ring, and the pulley assembly can slide up and down in the buffer assembly following the movable floating ring. The buoyancy strengthening assembly, the counterweight body, the anchor plate and the buoy body are coaxially arranged.

[0006] In this marine environment monitoring device, by installing meteorological element sensors, hydrological element sensors, marine ecological element monitoring sensors, etc. in the buoy body, the marine environment is monitored in real time. It can not only monitor and transmit marine environment data in real time, but also effectively resist sea waves and reduce the occurrence of mechanical fatigue.

[0007] The inner bottom surface of the buffer assembly is recessed inward towards the axis of the counterweight body, and the recessed depth gradually decreases towards the two end parts of the buffer assembly along the axis of the counterweight body.

[0008] The two side walls of the buffer assembly are recessed outward in opposite directions, and the recessed depth gradually decreases towards the two end parts of the buffer assembly along the axis of the counterweight body.

[0009] In this marine environment monitoring device, the buffer assembly cooperates with the movable floating ring to effectively buffer wave energy, reduce the damage probability of internal components of the device, and enhance the overall connection stability of the device. On the one hand, under the influence of the same wave, compared with the straight slideway in the prior art, the buffer assembly, through its bottom surface or side wall recessed structure, increases the traveling resistance of the rubber pulley, making the vertical displacement of the pulley assembly smaller. And when the pulley assembly moves up with the wave and reaches the end part of the buffer assembly, it can use its own gravitational potential energy and the elastic potential energy of the buffer spring in the pulley assembly to reset to the middle position of the buffer assembly in time. When the pulley assembly moves down with the wave to the end part of the buffer assembly, it can also use the elastic potential energy of the buffer spring in the pulley assembly to reset to the middle position of the buffer assembly in time, shortening the cycle of the reciprocating motion generated by the up and down movement of the movable floating ring with the wave.

[0010] On the other hand, the setting of the buffer component ensures that when the movable floating ring is subjected to a buoyancy threshold exceeding the threshold that it can withstand, that is, when it is subjected to large winds and waves, the movable floating ring will drive the pulley component to continuously hit the edge of the buffer tank. The device can reduce the force of the pulley assembly hitting the limit edge of the buffer tank through the bottom or side wall recessed structure of the buffer component, thereby reducing the chance of damage to the internal components of the device as a whole when facing repeatedly surging waves, thereby enhancing the overall connection stability of the device.

[0011] A carrying frame is provided on the buoy base, and the carrying frame has a main carrying rod and a supporting carrying rod. The main carrying rod is coaxially arranged perpendicular to the upper surface of the buoy base, and multiple supporting carrying rods are equidistantly arranged near the edge of the upper surface of the buoy base. One end of the supporting carrying rod is fixedly connected to a fixed plate, and a solar cell panel is provided between adjacent supporting carrying rods.

[0012] A protective ring is provided at the edge of the upper surface of the buoy base, an inspection port is provided on the upper surface of the buoy base, an annular flange is coaxially provided on the outer wall near the bottom surface of the buoy base, and a reinforcement block is fixedly connected between the annular flange and the outer wall of the buoy base.

[0013] The buoyancy reinforcement comprises four detachable floating blocks, each of which has a wedge-shaped block structure and a plurality of first connection holes are opened at the edge of the floating block.

[0014] The buoyancy reinforcement also includes a connecting column, and four connecting plates are equidistantly provided on the side wall of the connecting column in the circumferential direction, and a plurality of second connecting holes are opened on the connecting plates.

[0015] The floating block and the connecting plate are connected by stud bolts and nuts, and a stabilizing piece is coaxially arranged between the nut and the wall surface of the floating block.

[0016] The marine environment monitoring device, through the design of detachable floats, can solve the problem in the prior art that when a steel buoy base and a non-steel buoyancy reinforcement are directly connected by a connector, the connection end of the buoyancy reinforcement with low strength is prone to connection failure. For example, if a double-headed stud is used in combination with a nut for active connection, the connection end of the buoyancy reinforcement will be affected by stress concentration, and the first connection hole will be prone to cracking, thereby causing failure of the connector. The buoyancy reinforcement provided by the present device is fixedly connected to the bottom of the buoy base through a connecting column, and each float is connected to the second connection hole of the connecting plate on the connecting column through a double-headed stud and a nut, so that the force on both sides of the double-headed stud is balanced, avoiding the situation where the stress of the double-headed stud is concentrated on one side, thereby avoiding the connection end of the buoyancy reinforcement being affected by stress concentration, the connection end being prone to cracking, and causing failure of the connector.

[0017] The stabilizing member has a circular ring structure. A convex portion protruding outward is provided on one side wall of the stabilizing member, and a concave portion concave inward is provided on the other side wall of the stabilizing member.

[0018] For this marine environment monitoring device, by providing a stabilizing member between the nut and the wall surface of the floating block, the frictional force between the nut and the surface of the floating block can be increased, the stability of the connecting member can be enhanced, and the occurrence of mechanical fatigue can be slowed down. Moreover, when the stud and the nut are slightly loose or vibrate, the nut will squeeze the recessed portion of the stabilizing member, thereby squeezing out the air inside it. As a result, the recessed portion will generate an adsorption effect on the surface of the nut, further enhancing the stability of the connecting member and preventing further loosening of the stud.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. For this marine environment monitoring device, through the cooperation of the buffer assembly and the movable floating ring, the wave energy can be effectively buffered, the probability of damage to the internal components of the device can be reduced, and the overall connection stability of the device can be enhanced.

[0021] 2. For this marine environment monitoring device, through the design of the detachable floating block, it can solve the problem that when the steel floating buoy matrix and the non-steel buoyancy strengthening member in the prior art are directly connected by a movable connecting member, the connection end of the buoyancy strengthening member with lower strength is prone to connection failure.

[0022] 3. For this marine environment monitoring device, by providing a stabilizing member between the nut and the wall surface of the floating block, the frictional force between the nut and the surface of the floating block can be increased, the stability of the connecting member can be enhanced, and the occurrence of mechanical fatigue can be slowed down.

[0023] 4. For this marine environment monitoring device, through the provision of the stabilizing member, when the stud and the nut are slightly loose or vibrate, the recessed portion can prevent further loosening of the stud. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0041] Embodiment 1 provided by the present invention:

[0042] Please refer to the attached Figure 1-5 , a marine environment monitoring device, including a buoy base body 1, the buoy base body 1 having a hollow cylindrical structure; a buoyancy strengthening member 2, the buoyancy strengthening member 2 fixedly connected below the buoy base body 1; a counterweight base body 3, the counterweight base body 3 having a solid cylindrical structure, the counterweight base body 3 fixedly connected below the buoyancy strengthening member 2; an anchoring plate 4, the anchoring plate 4 fixedly connected below the counterweight base body 3; a movable floating ring 31 coaxially sleeved on the counterweight base body 3, the movable floating ring 31 having an annular structure, and 4 buffer grooves 32 are circumferentially and equidistantly opened on the outer side wall of the counterweight base body 3, buffer components 321 are respectively arranged in the buffer grooves 32, the outer wall surface of the buffer component 321 fits the inner wall surface of the buffer groove 32, a pulley component 33 is fixedly connected to the inner ring surface of the movable floating ring 31, and the pulley component 33 can slide up and down in the buffer component 321 following the movable floating ring 31. The buoyancy strengthening component, the counterweight base body 3, the anchoring plate 4 and the buoy base body 1 are coaxially arranged. Among them, the anchoring plate 4 has a disc-shaped structure, and a plurality of anchoring holes 41 are circumferentially opened near the edge of the anchoring plate 4, and the counterweight base body 3 is detachable in multiple sections.

[0043] This marine environment monitoring device installs meteorological element sensors, hydrological element sensors, marine ecological element monitoring sensors, etc. in the buoy base body 1 to monitor the marine environment in real time. It can not only monitor and transmit marine environment data in real time, but also effectively resist sea winds and waves and slow down the occurrence of mechanical fatigue.

[0044] Please continue to refer to the attached Figure 6-7 , the inner bottom surface of the buffer component 321 is recessed inward in the direction close to the axis of the counterweight base body 3, and the recessed depth gradually decreases along the axis direction of the counterweight base body 3 towards both ends of the buffer component 321.

[0045] The two side walls of the buffer component 321 are recessed outward in opposite directions, and the recessed depth gradually decreases along the axis direction of the counterweight base body 3 towards both ends of the buffer component 321. Among them, the side wall of the buffer component 321 is made of an elastic material, such as rubber, silica gel, etc.

[0046] This marine environment monitoring device can effectively buffer wave energy through the buffer assembly 321 in cooperation with the movable floating ring 31, reduce the probability of damage to internal components of the device, and enhance the overall connection stability of the device. On the one hand, under the influence of the same waves, compared with the straight slideway in the prior art, the buffer assembly 321, through its bottom surface or sidewall concave structure, increases the traveling resistance of the rubber pulley 332, making the vertical displacement of the pulley assembly 33 smaller. And when the pulley assembly 33 moves up with the waves and reaches the end of the buffer assembly 321, it can utilize its own gravitational potential energy and the elastic potential energy of the buffer spring 343 in the pulley assembly 33 to reset to the middle position of the buffer assembly 321 in time. When the pulley assembly 33 moves down with the waves to the end of the buffer assembly 321, it can also utilize the elastic potential energy of the buffer spring 343 in the pulley assembly 33 to reset to the middle position of the buffer assembly 321 in time, shortening the period of the reciprocating motion generated by the up and down movement of the movable floating ring 31 with the waves.

[0047] On the other hand, the setting of the buffer assembly 321 enables the movable floating body to drive the pulley assembly 33 to continuously impact the edge of the buffer groove 32 when it is subjected to a buoyancy threshold exceeding its tolerance, that is, when it bears strong winds and waves. The buffer assembly 321 can, through its bottom surface or sidewall concave structure, weaken the impact force when the pulley assembly 33 impacts the limiting edge of the buffer groove 32, so that when the whole device faces large waves with repeated ups and downs, the probability of damage to internal components of the device is reduced, and thus the overall connection stability of the device is enhanced.

[0048] Please refer to the appendix Figure 1-2 , a carrier frame 11 is provided on the buoy base 1. The carrier frame 11 has a carrier main rod 111 and carrier support rods 112. The carrier main rod 111 is coaxially arranged perpendicular to the upper surface of the buoy base 1. A plurality of carrier support rods 112 are equidistantly arranged near the edge of the upper surface of the buoy base 1. One end of each carrier support rod 112 is fixedly connected with a fixing plate 113, and a solar panel 114 is arranged between adjacent carrier support rods 112.

[0049] A protective ring 12 is provided at the edge of the upper surface of the buoy base 1. An inspection opening is provided on the upper surface of the buoy base 1. An annular flange 14 is coaxially provided on the outer side wall near the bottom surface of the buoy base 1, and a reinforcing block 141 is fixedly connected between the annular flange 14 and the outer side wall of the buoy base 1.

[0050] Please continue to refer to the appendix Figure 10-13 , the buoyancy reinforcement member 2 includes 4 detachable floating blocks 21. The floating blocks 21 have a wedge-shaped block structure, and a plurality of first connection holes 211 are opened at the edges of the floating blocks 21.

[0051] The buoyancy reinforcement member 2 further includes a connecting column 22. Four connecting plates 23 are circumferentially and equidistantly arranged on the side wall of the connecting column 22. A plurality of second connecting holes 231 are formed in the connecting plates 23.

[0052] The floating block 21 and the connecting plate 23 are connected by a stud bolt and a nut 25. A stabilizing member 26 is coaxially arranged between the nut 25 and the wall surface of the floating block 21.

[0053] In this marine environment monitoring device, through the design of the detachable floating block 21, it can solve the problem that when the steel buoy matrix 1 and the non-steel buoyancy reinforcement member 2 in the prior art are directly connected by a connecting member in a movable manner, the connecting end of the buoyancy reinforcement member 2 with lower strength is prone to connection failure. For example, when a stud bolt 24 is used in cooperation with a nut 25 for movable connection, the connecting end of the buoyancy reinforcement member 2 will be affected by stress concentration, and the first connecting hole 211 is prone to cracking, thus causing the connecting member to fail. The buoyancy reinforcement member 2 provided by this device is fixedly connected to the lower part of the buoy matrix 1 through the connecting column 22. Each floating block 21 is connected to the second connecting hole 231 on the connecting plate 23 by a stud bolt 24 and a nut 25, so that the forces on both sides of the stud bolt 24 are balanced, avoiding the situation where the stress on the stud bolt 24 is concentrated on one side, and further avoiding the problem that the connecting end of the buoyancy reinforcement member 2 is affected by stress concentration and the connecting end is prone to cracking, resulting in the failure of the connecting member.

[0054] Please continue to refer to the appendix Figure 14-15 The stabilizing member 26 has an annular structure. A protruding portion 261 protruding outward is provided on one side wall of the stabilizing member 26, and a recessed portion 262 recessed inward is provided on the other side wall of the stabilizing member 26.

[0055] In this marine environment monitoring device, through the stabilizing member 26 arranged between the nut 25 and the wall surface of the floating block 21, the friction between the nut 25 and the surface of the floating block 21 can be increased, the stability of the connecting member can be enhanced, and the occurrence of mechanical fatigue can be slowed down. And when the stud bolt 24 and the nut 25 are slightly loosened or shaken, the nut 25 will squeeze the recessed portion 262 of the stabilizing member 26, so that the air inside it is squeezed out, and then the recessed portion 262 will generate an adsorption effect on the surface of the nut 25, further enhancing the stability of the connecting member and preventing the stud bolt 24 from loosening further.

[0056] Embodiment 2 provided by the present invention:

[0057] Please refer to the appendix Figure 4-7 Based on Embodiment 1, the inner bottom surface of the buffer assembly 321 is recessed inward in the direction close to the axis of the counterweight matrix 3, and the recessed depth gradually decreases along the axis direction of the counterweight matrix 3 towards both ends of the buffer assembly 321. The two side walls of the buffer assembly 321 are recessed outward in opposite directions, and the recessed depth gradually decreases along the axis direction of the counterweight matrix 3 towards both ends of the buffer assembly 321.

[0058] By combining the different structures of the two buffer components 321 provided in the first embodiment, the marine environment monitoring device provides a variety of buffer components 321 for actual needs. For example, in the face of different sea areas, different seasons, and different marine climates, the sizes of the sea waves are also different. The buffer components 321 can be selectively replaced to balance the requirements for the performance of each aspect of the device. For example, on the basis of this device, if a wave energy generator in the prior art is carried, and the wave energy generator requires the movable floating ring 31 to be more sensitive to the perception of waves, so as to increase the number of rotations of the generator motor. Therefore, in the above situation, one of the two buffer components 321 with different structures provided in the first embodiment can be selected. When facing a harsh marine climate with large and frequent sea surface winds and waves, the solution provided in this embodiment should be selected.

[0059] Embodiment 3 provided by the present invention:

[0060] Please refer to the attached Figure 4-9 , based on the first embodiment, the pulley assembly 33 has a mounting bent plate 331, a rubber pulley 332 is axially connected to the mounting bent plate 331, a buffer shaft 333 is provided on the mounting bent plate 331, the axis of the buffer shaft 333 and the axis of the rubber pulley 332 are vertically intersecting, a buffer sleeve 34 is coaxially provided on the buffer shaft 333, the buffer shaft 333 and the buffer sleeve 34 are movably connected by a screw 341 and a screw 342, a buffer spring 343 is coaxially provided inside the buffer sleeve 34, a buffer boss 334 is provided on the buffer shaft 33 to abut against the buffer spring 343, and the inside of the buffer shaft 33 is hollow and has an internal thread structure.

[0061] The marine environment monitoring device, through the design of the pulley assembly 33, uses the connection method that one end of the screw 341 is screwed into the inside of the buffer shaft 333 and the other end of the screw 341 is pivotally connected to the buffer sleeve. When the rubber pulley 332 passes through the concave structure on the bottom surface of the buffer assembly 321, the force on the rubber pulley 332 can be transmitted to the buffer shaft 333. The internal thread structure in the buffer shaft 333 causes the screw 341 pivotally connected to the buffer sleeve 34 to rotate, and at the same time compresses the buffer spring 343 by the buffer boss 334 of the buffer shaft 333. Thus, the rubber pulley 332 can adapt to the concave structure of the buffer assembly 321, and play a buffering role in the overall force on the pulley assembly 33, so as to achieve the purpose of reducing the vibration energy generated by the overall device affected by waves. The elastic potential of the buffer spring 343 and the self-rotation of the screw 341 can also cooperate with the buffer assembly 321 to make the movement speed of the movable floating ring 31 more tend to linear change, control the period of the reciprocating motion of the movable floating ring 31 caused by the undulation of the waves, reduce the number of times the movable floating ring 31 reaches the buoyancy threshold due to continuously bearing multiple superimposed waves, and also reduce the number of times the pulley assembly 33 hits the edge of the buffer groove driven by the movable floating ring 31.

[0062] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
