Description

Technical Field

[0001] This invention relates to the technical field of power generation devices, and more specifically to a power generation device for mooring cables of deep-sea aquaculture cages. Background Technology

[0002] Deep-sea aquaculture is an important direction for expanding aquaculture space and developing the blue economy. Floating cages, as its core equipment, are highly dependent on a continuous and stable power supply for normal operation. Currently, the main ways to provide power to deep-sea aquaculture cages include: external power transmission via submarine cables, power supply via battery packs on the cages themselves, or power generation units such as solar photovoltaic panels and small wind turbines installed on the cage floats and other structures.

[0003] However, all of the above-mentioned power supply methods have significant limitations in the complex environment of the deep sea. External power transmission requires laying long-distance submarine cables, which are extremely costly to install and maintain, and these cables are easily damaged in harsh sea conditions. Self-supplied battery banks suffer from low energy density, require frequent replacement or return to port for charging, resulting in high operation and maintenance costs and an inability to provide long-term uninterrupted power supply. While solar and wind power generation units can achieve on-site energy extraction, their power generation efficiency is greatly affected by day / night cycles, seasons, and weather and sea conditions, leading to discontinuous and unstable power supply. Furthermore, the equipment is easily damaged in extreme sea conditions such as typhoons and giant waves, making maintenance difficult.

[0004] Therefore, the existing technologies mentioned above are insufficient to meet the urgent need for low-cost, continuous, and stable power supply for deep-sea aquaculture cages. A new power supply solution that can adapt to the deep-sea environment and utilize local stable energy sources is urgently needed. It is worth noting that deep-sea aquaculture cages are fixed in position using mooring cables. Under the continuous action of waves, the mooring cables will inevitably experience periodic tension and relaxation responses, containing abundant and continuously usable mechanical energy. How to effectively recover and utilize this mechanical energy, converting it into electrical energy to provide the cages with a simple structure, convenient installation and maintenance, and a continuous and stable supplementary power supply has become a pressing technical problem to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to improve a deep-sea aquaculture cage mooring cable power generation device, which aims to recover and utilize the mechanical energy of the cage mooring cable to generate electricity, thereby providing power to the deep-sea aquaculture cages in a low-cost, continuous and stable manner.

[0006] To address the above problems, this invention provides a deep-sea aquaculture cage mooring cable power generation device, comprising: Cable securing mechanism, used to connect to the mooring cables of the fish cage; A cable routing mechanism includes a fixing component and a cable routing component, one end of the fixing component being used to connect to a cage, and the cable routing component being disposed at the other end of the fixing component; The power generation mechanism includes a power generation box for installation in a net cage, and a transmission assembly and a generator installed in the power generation box, the power generation box being provided with a line inlet. The transmission cable has its first end connected to the cable fixing mechanism, and its tail end passes through the cable assembly and enters the generator box through the inlet hole, and is connected to the input end of the transmission assembly. When the mooring cables of the cage are tensioned, the transmission cable is pulled by the cable fixing mechanism. The transmission component converts the linear motion of the transmission cable into rotational motion and outputs it to the generator to generate electricity. When the mooring cables of the cage are slack, the transmission cable is retracted by the transmission component for the next cycle of power generation.

[0007] The above-described scheme converts the tension and relaxation mechanical motion of the mooring cables of the net cage into the linear motion of the transmission cable by setting up a cable fixing mechanism. Simultaneously, a cable arrangement mechanism solves the problem of tangling and knotting of the transmission cable during long-distance, high-degree-of-freedom movement, ensuring the stable transmission of the linear motion of the transmission cable to the power generation mechanism. Finally, the transmission components of the power generation mechanism convert the linear motion of the transmission cable into rotational motion, which is then output to the generator to generate electricity. Compared with existing technologies, this scheme has a simple overall structure, can be installed mainly based on existing net cages and mooring cables, requires no complex seabed engineering or large support structures, and is simple to install and maintain, with low cost. Furthermore, the wave action on the mooring cables is continuous, ensuring the continuity and stability of the power generation mechanism during power generation.

[0008] In an improved embodiment, the cable fixing mechanism includes two clamping plates and two clamps. The two clamping plates form a cylindrical structure for clamping the mooring cable of the cage. The two clamps are respectively fitted onto both ends of the cylindrical structure formed by the two clamping plates. The two clamping plates clamp the mooring cable from both sides, ensuring a large contact area with the mooring cable, thereby ensuring greater friction and connection stability. The two clamps, respectively fitted onto both ends of the cylindrical structure formed by the two clamping plates, not only help to fix the two clamping plates but also provide axial stops, effectively preventing the cable fixing mechanism from sliding along the mooring cable during tension and relaxation movements, thus ensuring the stability of capturing the tension and relaxation mechanical movements of the mooring cable.

[0009] In an improved embodiment, the cable fixing mechanism further includes a pulley block connected to the outer wall of any of the jacket plates, with the first end of the transmission cable wound around the pulley block. Integrating the pulley block into the cable fixing mechanism provides a movable connection point for the transmission cable, avoiding a direct rigid connection between the transmission cable and the jacket plate. This results in smoother, linear movement of the transmission cable, improving transmission efficiency and service life.

[0010] In an improved embodiment, the fixing assembly includes a connecting rod and a cable tray box. One end of the connecting rod has a mounting portion for connecting to the mesh cage, and the other end is connected to the cable tray box via a universal joint. The cable tray box has a threading inlet and a threading outlet on both sides for the transmission cable to pass through. The cable tray assembly is disposed inside the cable tray box and located between the threading inlet and outlet. The other end of the connecting rod is connected to the cable tray box via a universal joint, giving the cable tray box a certain degree of self-adjustment capability, allowing it to flexibly swing and rotate according to the actual force direction of the transmission cable, thereby reducing the risk of friction and uneven wear between the transmission cable and the cable tray box.

[0011] In an improved embodiment, the cable routing assembly includes a cable routing drum, which is rotatably connected inside the cable routing box and coaxially arranged with the cable inlet and outlet. The interior of the cable routing drum has a first guide wheel near the cable inlet and a second guide wheel near the cable outlet. The axes of the first and second guide wheels are perpendicular to the axis of the cable routing drum. The transmission cable entering through the cable inlet passes sequentially around the first and second guide wheels and exits through the cable outlet. The position of the first guide wheel for inputting the transmission cable is eccentrically positioned relative to the cable routing drum, and the position of the second guide wheel for outputting the transmission cable is located on the axis of the cable routing drum. When the drive cable enters the cable tray at any angle through the threading hole and passes around the first guide wheel, the lateral force of the drive cable itself will cause the entire cable tray drum to rotate, thereby eliminating the lateral force. Finally, the drive cable is output from the second guide wheel along the axis of the cable tray drum and passes through the threading hole. This fundamentally solves the technical problem of drive cables being prone to tangling and knotting in complex sea conditions, ensuring the smoothness of the linear movement of the drive cable.

[0012] In an improved embodiment, the cable tray box has a rotating hole for the cable tray drum to rotate and the axis of the rotating hole is set in the horizontal direction. The end of the cable tray drum near the cable insertion outlet has a coaxial turntable. The side of the turntable facing the cable insertion outlet has a bracket for the second guide wheel to rotate and connect. The cable tray assembly also includes a pulley, a support shaft, and a support base. The pulley is located above the turntable and is rotatably connected to the cable tray box with its axis parallel to the cable tray drum. A transmission belt is wound between the pulley and the turntable. The support base is connected to the cable tray box and has a positioning end extending to the bottom of the turntable. The support shaft is rotatably inserted into the cable tray drum and has a limiting end that extends out of the turntable and bends downward. A gap is left between the positioning end and the limiting end for the bracket to pass through, and magnets are provided at the positioning end and the limiting end to achieve mutual attraction. With the above structure, the pulley provides an upward suspension force to the turntable through the transmission belt, providing upward support for the cable winding drum; at the same time, the limiting end of the support shaft inside the cable winding drum is subjected to a downward magnetic attraction force from the positioning end of the support seat, providing a downward limiting effect for the cable winding sleeve. The combination of the two ensures that the end of the cable winding drum near the cable exit hole has a certain degree of flexibility when rotating, and will automatically reset after deflection, making the operation stable and reliable, and significantly reducing mechanical wear.

[0013] In an improved embodiment, the transmission assembly includes a first rotating member and a second rotating member spaced apart within the generator box, a pulley assembly located between the first and second rotating members, and a transmission wheel assembly located between the second rotating member and the generator. The pulley assembly includes a transfer cable, at least one fixed pulley rotatably connected within the generator box, a slide table slidably connected within the generator box, and at least one movable pulley rotatably connected to the slide table. The transmission cable, entering through the inlet hole, passes around the first rotating member and connects to one side of the slide table. One end of the transfer cable is connected to the fixed pulley, and the other end passes around the movable pulley and connects to the second rotating member. When the transmission cable through the inlet hole is pulled outward, the slide table is pulled and moves towards the side of the transmission cable, thereby causing the transfer cable to pull the second rotating member to rotate. The rotation of the second rotating member is transmitted to the generator via the transmission wheel assembly to generate electricity. The generator box is equipped with a spring connected to the other side of the slide table and used to drive the slide table to return to its original position. By introducing a pulley assembly between the first and second rotating components, the linear motion stroke of the transmission cable can be amplified many times, thereby enabling the second rotating component to obtain a larger rotation angle, significantly improving the response sensitivity to small waves and the overall power generation efficiency.

[0014] In an improved embodiment, the first rotating component includes a first coil spring, a first rotating shaft connected within the generator box, and a first drum rotatably sleeved on the first rotating shaft. One end of the first coil spring is connected to the first drum, and the other end is connected to the first rotating shaft or the generator box. A drive cable entering through the inlet hole winds around the first drum and connects to a slide. When the drive cable through the inlet hole is pulled outward, the first drum rotates relative to the first rotating shaft, and the first coil spring is pulled open to accumulate elastic potential energy. The slide is pulled and moves towards the side of the drive cable. When the external force on the drive cable through the inlet hole disappears, the first coil spring releases its elastic potential energy and drives the first drum to rotate in the opposite direction. At the same time, the spring drives the slide to reset. The first coil spring serves as a filter and energy storage function. When the mooring cable is tensioned by the wave impact and pulls the drive cable, generating pulsed mechanical energy, the linear motion of the drive cable will be transmitted and converted into the rotation of the first drum and the pulling of the slide. At this time, due to the presence of the first coil spring, the drive cable can drive the slide in a relatively smooth and continuous state, thereby effectively buffering the impact caused by sudden changes in sea state, protecting the transmission system, and improving the stability of the power generation process and the overall durability.

[0015] In an improved embodiment, the second rotating component includes a second coil spring, a second rotating shaft rotatably connected within the generator box, and a second drum rotatably sleeved on the second rotating shaft. One end of the second coil spring is connected to the second drum, and the other end is connected to the generator box. The other end of the adapter cable is wound around the second drum. The transmission wheel set includes an input gear connected to the second rotating shaft and an output gear connected to the generator's main shaft. The second drum is designed to rotate in a unidirectional manner relative to the second rotating shaft. The direction of unidirectional rotation is as follows: when the slide is pulled to one side of the transmission cable, the adapter cable is pulled and drives the second drum to rotate. At this time, the second drum and the second rotating shaft are in a non-rotatable state relative to each other. Therefore, the second drum will drive the second rotating shaft to rotate synchronously. The second rotating shaft drives the generator's main shaft to rotate through the transmission wheel set to generate electricity. At the same time, the second coil spring is pulled open and accumulates elastic potential energy. When the slide is driven back to its original position by the spring, the second coil spring releases its elastic potential energy and drives the second drum to rotate in the opposite direction. At this time, the second drum and the second rotating shaft are in a rotatable state relative to each other. Therefore, the second drum can rotate in the opposite direction to achieve a reset. With the above structure, since the second drum is designed to rotate in one direction relative to the second shaft, the rotation direction of the second shaft can be kept consistent, which in turn makes the rotation direction of the generator's main shaft consistent, ultimately achieving consistent power output direction. Power can be used directly without additional rectifier devices, while the second coil spring is used to achieve the reverse rotation and reset of the second drum.

[0016] In an improved design, a ratchet is provided at one end of the second rotating shaft, and a pawl is provided at one end of the second drum. The pawl engages with the ratchet to achieve unidirectional rotation of the second drum relative to the second rotating shaft, resulting in a simple and reliable structure.

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1-15 An embodiment of the present invention provides a deep-sea aquaculture cage mooring cable power generation device, comprising: Cable fixing mechanism 2, used to connect to the mooring cable 11 of the net cage 1; The cable routing mechanism 3 includes a fixing component 31 and a cable routing component 32. One end of the fixing component 31 is used to connect to the cage 1, and the cable routing component 32 is disposed at the other end of the fixing component 31. The power generation mechanism 4 includes a power generation box 41 for installation to the net cage 1, and a transmission assembly and a generator 411 installed in the power generation box 41. The power generation box 41 is provided with an inlet hole 41a. The transmission cable 5 is connected at its first end to the cable fixing mechanism 2, and at its tail end, after passing through the cable assembly 32, enters the generator box 41 through the inlet hole 41a and is connected to the input end of the transmission assembly. When the mooring cable 11 of the cage 1 is tensioned, the transmission cable 5 is pulled through the cable fixing mechanism 2. The transmission component converts the linear motion of the transmission cable 5 into rotational motion and outputs it to the generator 411 to generate electricity. When the mooring cable 11 of the cage 1 is slack, the transmission cable 5 is retracted by the transmission component for the next cycle of power generation.

[0024] The above scheme converts the tension and relaxation mechanical motion of the mooring cable 11 of the cage 1 into the linear motion of the transmission cable 5 by setting up a cable fixing mechanism 2. At the same time, the cable laying mechanism 3 solves the problem of tangling and knotting of the transmission cable 5 during long-distance, high-degree-of-freedom motion, ensuring that the linear motion of the transmission cable is stably transmitted to the power generation mechanism 4. Finally, the transmission component of the power generation mechanism 4 converts the linear motion of the transmission cable 5 into rotational motion and outputs it to the generator 411 to generate electricity. Compared with the prior art, the entire device structure of this scheme is simple, and it can be installed mainly based on the existing cage 1 and mooring cable 11. It does not require complex seabed engineering or large support structures, and the installation and maintenance are simple and low-cost. At the same time, the effect of waves on the mooring cable 11 is continuous, ensuring the continuity and stability of power generation by the power generation mechanism 4.

[0025] refer to Figures 3-5As shown, in this embodiment, the cable fixing mechanism 2 includes two clamping plates 21, which together form a cylindrical structure. The position between the two clamping plates 21 is used to clamp the mooring cable 11 of the cage 1, and the two clamping plates 21 can be directly connected and fixed by bolts. Furthermore, the cable fixing mechanism 2 also includes two annular clamps 22, each clamp 22 including two semi-annular plates. The two ends of the two semi-annular plates are connected by bolts and dovetail grooves to form an annular clamp 22. The two clamps 22 are respectively fitted onto the two ends of the cylindrical structure formed by the two clamping plates 21. Two clamping plates 21 clamp the mooring cable 11 from both sides, ensuring a large contact area with the mooring cable 11, thereby guaranteeing greater friction and connection stability. Two clamps 22 are respectively fitted onto the ends of the cylindrical structure formed by the two clamping plates 21, which not only helps to fix the two clamping plates 21 but also provides axial stops, effectively preventing the cable fixing mechanism 2 from sliding along the mooring cable 11 during tensioning and relaxation, ensuring the stability of capturing the tensioning and relaxation mechanical movement of the mooring cable 11. It should be understood that the clamping plates 21 and clamps 22 can also be replaced with any other existing structure capable of connecting and fixing the head end of the transmission cable 5 to the mooring cable 11 of the cage 1, such as buckles, knots, locking blocks, etc. This design does not limit this.

[0026] At the same time, combined Figure 3 As shown, the cable fixing mechanism 2 also includes a pulley block 23, which is connected to the outer wall of any of the clamping plates 21. The first end of the transmission cable 5 is wound around the pulley block 23. Integrating the pulley block 23 into the cable fixing mechanism 2 provides a movable connection point for the transmission cable 5, avoiding a direct rigid connection between the transmission cable 5 and the clamping plate 21. This makes the linear movement of pulling the transmission cable 5 smoother and more efficient, improving transmission efficiency and service life.

[0027] like Figure 6 As shown, the fixing component 31 in this embodiment includes a connecting rod 311 and a cable tray 313. One end of the connecting rod 311 is provided with a mounting part for connecting the wire mesh box 1, and the other end is connected to the cable tray 313 via a universal joint 312. The cable tray 313 has a wire inlet hole 313a and a wire outlet hole 313b on both sides for the transmission cable 5 to pass through. The cable tray assembly 32 is disposed inside the cable tray 313 and located between the wire inlet hole 313a and the wire outlet hole 313b. The other end of the connecting rod 311 is connected to the cable tray 313 via a universal joint 312, which gives the cable tray 313 a certain self-adjusting capability, allowing it to swing and rotate flexibly according to the actual force direction of the transmission cable 5, thereby reducing the risk of friction and uneven wear between the transmission cable 5 and the cable tray 313. Considering that the rotation angle of the transmission cable 5 located on the side of the cable inlet hole is usually large, the diameter of the cable inlet hole is designed to be larger than that of the cable outlet hole.

[0028] like Figure 7 and Figure 8 As shown, in this embodiment, the cable assembly 32 includes a cable drum 321. The cable drum 321 is rotatably connected to the cable box 313 and is coaxially arranged with the cable inlet hole 313a and the cable outlet hole 313b. The cable drum 321 has a first guide wheel 321a at one end near the cable inlet hole 313a and a second guide wheel 321b at one end near the cable outlet hole 313b. The axes of the first guide wheel 321a and the second guide wheel 321b are both perpendicular to the axis of the cable drum 321. The transmission cable 5 entering through the cable inlet hole 313a passes through the first guide wheel 321a and the second guide wheel 321b in sequence and then exits through the cable outlet hole 313b. The position of the first guide wheel 321a for the input of the transmission cable 5 is eccentrically arranged relative to the cable drum 321, and the position of the second guide wheel 321b for the output of the transmission cable 5 is located on the axis of the cable drum 321. When the transmission cable 5 enters the cable tray 313 from the cable entry hole 313a at any angle and passes around the first guide wheel 321a, the lateral force of the transmission cable 5 itself will drive the entire cable tray drum 321 to rotate, thereby eliminating the lateral force. Finally, the transmission cable is output from the second guide wheel 321b along the axial direction of the cable tray drum 321 and passes through the cable exit hole 313b. This fundamentally solves the technical problem of the transmission cable 5 being prone to tangling and knotting under complex sea conditions, and ensures the smoothness of the linear movement of the transmission cable 5.

[0029] Furthermore, such as Figure 9 and Figure 10As shown, the cable tray 313 has a rotating hole 313c for the cable tray drum 321 to rotate and connect, and the axis of the rotating hole 313c is set in the horizontal direction. The end of the cable tray drum 321 near the cable insertion outlet is provided with a coaxial turntable 321c. The side of the turntable 321c facing the cable insertion outlet is provided with a bracket 321d for the second guide wheel 321b to rotate and connect. The cable tray assembly 32 also includes a pulley 322, a support shaft 323 and a support base 324. The pulley 322 is located above the turntable 321c and rotates with its axis parallel to the cable tray drum 321. The drive belt 322a is wound between the pulley 322 and the turntable 321c and is connected to the cable box 313. The support base 324 is connected to the cable box 313 and has a positioning end 324a extending to the bottom of the turntable 321c. The support shaft 323 is rotatably inserted into the cable drum 321 and has a limiting end 323a that passes through the turntable 321c and bends downward. There is a gap between the positioning end 324a and the limiting end 323a for the bracket 321d to pass through. The positioning end 324a and the limiting end 323a are provided with magnets to achieve mutual attraction. With the above structure, pulley 322 provides an upward suspension force to turntable 321c through transmission belt 322a, providing upward support for cable winding drum 321; at the same time, the limiting end 323a of the support shaft 323 inside the cable winding drum 321 is subjected to a downward magnetic attraction force from the positioning end 324a of the support seat 324, providing a downward limiting effect for the cable winding sleeve. The combination of the two ensures that the end of the cable winding drum 321 near the cable outlet hole 313b has a certain degree of flexibility when rotating, and will automatically reset after deflection, making the operation stable and reliable, and significantly reducing mechanical wear.

[0030] like Figures 11-14 As shown, the transmission assembly includes a first rotating member 42 and a second rotating member 43 spaced apart within the generator box 41, a pulley assembly 44 located between the first rotating member 42 and the second rotating member 43, and a transmission wheel set 45 located between the second rotating member 43 and the generator 411. The pulley assembly 44 includes a transfer cable 441, at least one fixed pulley 442 rotatably connected within the generator box 41, a slide 443 slidably connected within the generator box 41, and at least one movable pulley 444 rotatably connected to the slide 443. Figure 13Based on this embodiment, the slide 443 is vertically slidably connected to the generator box 41. The fixed pulley 442 is located above the slide 443. The transmission cable 5, which enters through the inlet hole 41a, passes through the first rotating member 42 and is connected to the lower side of the slide 443. To ensure that the transmission cable 5 is connected to the lower side of the slide 443, a limiting wheel 424 is provided inside the generator box 41 below the first rotating member 42. The transmission cable 5 of the first rotating member 42 is connected to the lower side of the slide 443 after passing through the limiting wheel 424. One end of the connecting cable 441 is connected to the fixed pulley 442, and the other end is wound around the movable pulley 444 and then connected to the second rotating member 43. When the transmission cable 5 in the inlet hole 41a is pulled outward, the slide 443 is pulled downward, thereby the connecting cable 441 pulls the second rotating member 43 to rotate. The rotation of the second rotating member 43 is transmitted to the generator 411 through the transmission wheel assembly 45 to generate electricity. The generator box 41 is equipped with a spring 412 connected to the upper side of the slide 443 and used to drive the slide 443 to return to its original position. By introducing the pulley assembly 44 between the first rotating member 42 and the second rotating member 43, the linear motion stroke of the transmission cable 5 can be amplified many times, thereby allowing the second rotating member 43 to obtain a larger rotation angle, significantly improving the response sensitivity to small waves and the overall power generation efficiency. It should be understood that the number of fixed pulleys 442 and movable pulleys 444 can be increased or decreased as needed, for example... Figure 14 There are two fixed pulleys 442 and two movable pulleys 444. One end of the adapter cable 441 is connected to the fixed pulley 442 on the left. The tail end of the adapter cable 441 then winds around the movable pulley 444 on the left, the fixed pulley 442 on the right, and the movable pulley 444 on the right before connecting to the second rotating component 43. At this time, after passing the pulley assembly 44, the linear motion stroke of the transmission cable 5 has a four-fold amplified travel stroke at the end of the adapter cable 441.

[0031] In this embodiment, the first rotating component 42 includes a first coil spring 421, a first rotating shaft 422 connected inside the generator box 41, and a first drum 423 rotatably sleeved on the first rotating shaft 422. One end of the first coil spring 421 is connected to the first drum 423 and the other end is connected to the first rotating shaft 422 or the generator box 41. The transmission cable 5, which enters through the inlet hole 41a, passes around the first drum 423 and is then connected to the slide table 443. Figure 13Based on this, when the transmission cable 5 of the inlet hole 41a is pulled outward, the first drum 423 rotates clockwise relative to the first rotating shaft 422, and at the same time the first coil spring 421 is pulled open to accumulate elastic potential energy, and the slide table 443 is pulled downward; when the external force on the transmission cable 5 of the inlet hole 41a disappears, the first coil spring 421 releases elastic potential energy and drives the first drum 423 to rotate counterclockwise, and at the same time the spring 412 drives the slide table 443 to return to its original position. The first coil spring 421 serves as a filter and energy storage mechanism. When the mooring cable 11 is tensioned by wave impact and pulls the transmission cable 5, generating pulsed mechanical energy, the linear motion of the transmission cable 5 is transmitted and converted into the rotation of the first drum 423 and the pulling of the slide 443. At this time, due to the presence of the first coil spring 421, the transmission cable 5 can drive the slide 443 in a relatively smooth and continuous state, thereby effectively buffering the impact caused by sudden changes in sea state, protecting the transmission system, and improving the stability of the power generation process and the overall durability. Of course, the first rotating component 42 can also simply be a limiting wheel 424 rotatably connected inside the generator box 41, which is also within the scope of protection of this design.

[0032] In this embodiment, the second rotating component 43 includes a second coil spring 431, a second rotating shaft 432 rotatably connected to the generator box 41, and a second drum 433 rotatably sleeved on the second rotating shaft 432. One end of the second coil spring 431 is connected to the second drum 433 and the other end is connected to the generator box 41. The other end of the adapter cable 441 is wound around the second drum 433. The transmission wheel set 45 includes an input gear 451 connected to the second rotating shaft 432 and an output gear 452 connected to the main shaft of the generator 411. The second drum 433 is designed to rotate unidirectionally relative to the second rotating shaft 432, and the direction of unidirectional rotation is: with Figure 13Based on this, when the second drum 433 rotates counterclockwise, the second drum 433 and the second shaft 432 are in a non-rotatable state relative to each other; when the second drum 433 rotates clockwise, the second drum 433 and the second shaft 432 are in a rotatable state relative to each other; when the slide table 443 is pulled downward by the transmission cable 5, the adapter cable 441 is pulled, causing the second drum 433 to rotate counterclockwise relative to the second shaft 432. At this time, the second drum 433 and the second shaft 432 are in a non-rotatable state relative to each other, therefore the second drum 433 will drive the second shaft 432 to rotate synchronously counterclockwise. The main shaft of the generator 411 is rotated by the transmission wheel set 45 to generate electricity, while the second coil spring 431 is pulled open to accumulate elastic potential energy. When the slide table 443 is driven upward to reset by the spring 412, the second coil spring 431 releases its elastic potential energy and drives the second drum 433 to rotate clockwise. At this time, the second drum 433 and the second shaft 432 are in a state of relative rotation, so the second drum 433 can rotate clockwise to reset. Since the second shaft 432 is connected to the main shaft of the generator 411 through the transmission wheel set 45, the required rotational torque is large, and it tends to remain in a stationary state. With the above structure, since the second drum 433 is designed to rotate in one direction relative to the second shaft 432, the rotation direction of the second shaft 432 can be kept consistent, and thus the rotation direction of the main shaft of the generator 411 can also be kept consistent. Finally, the output direction of electrical energy is consistent, and electrical energy can be used directly without additional rectification devices. The second coil spring 431 is used to realize the reverse rotation reset of the second drum 433.

[0033] More specifically, such as Figure 15 As shown, one end of the second rotating shaft 432 is provided with a ratchet 61, and one end of the second drum 433 is provided with a pawl 62. The pawl 62 engages with the ratchet 61 to achieve unidirectional rotational engagement between the second drum 433 and the second rotating shaft 432. The structure is simple and reliable. Of course, the ratchet 61 and pawl 62 can also be replaced with other existing devices that can achieve unidirectional rotational engagement, such as a one-way overrunning clutch, which are also within the scope of protection of this design.

[0034] Furthermore, the specific form of the transmission gear set 45 is not limited in this design. In this embodiment, the transmission gear set 45 includes a rotatable intermediate shaft located between the second rotating shaft 432 and the generator 411, a large gear sleeved on the second rotating shaft 432, a small gear sleeved on one end of the intermediate shaft and meshing with the large gear, a large bevel gear sleeved on the other end of the intermediate shaft, and a small bevel gear connected to the main shaft of the generator 411. The large gear is the input gear 451 of the transmission gear set 45, and the small bevel gear is the output gear 452 of the transmission gear set 45. Thus, the rotation of the second rotating shaft 432 is transmitted to the main shaft of the generator 411 via the large gear, small gear, large bevel gear, and small bevel gear, achieving a two-stage amplification of the rotation angle. The number of teeth on the large gear, small gear, large bevel gear, and small bevel gear can be freely adjusted according to the needs of the site environment to achieve the optimal transmission ratio.
