Description

Technical Field

[0001] This invention relates to the field of energy storage technology, specifically to a low-carbon building non-structural component energy storage device. Background Technology

[0002] With increasing global concern over climate change and resource consumption, low-carbon buildings, as an important component of sustainable development, aim to reduce the environmental burden throughout the building's life cycle through energy-saving technologies, renewable energy utilization, and carbon emission management. Within this framework, energy storage devices have become a key link in balancing building energy supply and demand and improving the utilization rate of renewable energy. In existing low-carbon buildings, non-structural energy storage devices are gradually gaining attention due to their advantages such as not altering the building's structural load-bearing system and being easy to modularly integrate and replace. Common technical approaches include encapsulating phase change materials in partition walls or ceilings to achieve thermal energy storage, or embedding battery modules in decorative components to store electrical energy. Photovoltaic panels, as widely used clean energy collection devices in buildings, typically work in conjunction with the aforementioned energy storage devices: when there is sufficient sunlight, photovoltaic panels convert solar energy into electrical energy and store it in batteries or other energy storage media for use in building lighting, HVAC, and low-voltage equipment. However, existing non-structural energy storage devices for low-carbon buildings still have significant shortcomings in practical applications. Since they mainly rely on photovoltaic power generation as the sole renewable energy input, the energy storage effect of the devices is severely limited by weather conditions. During continuous rainy weather or at night, photovoltaic panels cannot effectively generate electricity, resulting in the energy storage devices being in a low-power or idle state for a long time, making it difficult to continuously provide stable power support for buildings. Especially in rainy areas, the rainy season lasts for a long time, and the efficiency of photovoltaic power generation drops significantly. Non-structural energy storage devices also lack other supplementary energy input channels, which greatly reduces the overall utilization rate and economic efficiency of the devices. There is no existing technology that can utilize the energy of rainwater itself to convert electricity and supplement the same energy storage device under rainy conditions. This limits the applicability and reliability of non-structural energy storage devices for low-carbon buildings in all-weather, multi-climate scenarios. Summary of the Invention

[0011] Preferably, the length of the first ball extending into the inner cavity of the first slot is less than its radius, and the length of the second ball extending into the inner cavity of the second slot is less than its radius.

[0012] The present invention proposes a low-carbon building non-structural component energy storage device, the advantages of which are as follows: 1. Under sunny conditions, this invention utilizes photovoltaic panels for photoelectric conversion and stores electrical energy in an energy storage unit, realizing the direct utilization of solar energy. This fully utilizes the sun-receiving area of ​​building roofs or non-structural components, thereby increasing the self-sufficiency rate of renewable energy without increasing additional land occupation.

[0013] 2. In rainy weather, this invention collects rainwater from the surface and surrounding area of ​​the photovoltaic panel through a water collection trough and guides the rainwater into a water cup. As the weight of the water cup increases, when the weight of the rainwater exceeds the preload of the counterweight and spring, the right rack automatically moves downward, driving the gear and power rod to rotate, and at the same time closing the water outlet to stop collecting water. This achieves automatic triggering of rainwater energy and mechanical water collection control, without the need for electronic sensors or external energy sources. The structure is simple and highly reliable.

[0014] 3. As the right rack moves downward, the water cup and the shielding cylinder descend synchronously. With the help of the spiral groove and the sliding column, the shielding cylinder automatically rotates 180 degrees during the descent, so that the first drain outlet and the second drain outlet coincide, and the rainwater in the water cup is discharged instantly. Then, under the action of the counterweight, the rack resets, the water outlet reopens, and the next round of water collection begins. Thus, the automatic drainage and reset cycle is completed by a purely mechanical mechanism, which ensures that the device can work repeatedly under continuous rainfall conditions and realizes the continuous collection of intermittent rainwater energy.

[0015] 4. In this invention, the power rod rotates clockwise during the water intake phase and counterclockwise during the drainage and reset phase. Both rotations are achieved through the cooperation of the first bevel gear, the second bevel gear, the third bevel gear, and two sets of pawls and ratchet wheels. Ultimately, the output rod is driven to rotate in the same direction (counterclockwise) at all times. This transforms the bidirectional discontinuous input motion into a single-direction rotational output, avoiding energy waste and providing a stable power source for the subsequent energy storage mechanism.

[0016] 5. In this invention, when the output rod rotates counterclockwise, the second pawl seat and the fourth pawl drive the fourth ratchet and the take-up reel to rotate counterclockwise. The take-up reel winds the pull rope and slowly lifts the second counterweight up along the inclined slide plate, converting the small gravitational potential energy of the rainwater into the high potential energy of the counterweight and storing it temporarily. This adopts a slow energy storage strategy, solving the problem that rainwater has low energy and low power and cannot directly drive the generator, thus allowing the dispersed rainwater energy to accumulate.

[0017] 6. When the second counterweight is lifted to the top of the slide plate, it touches and pushes the pull rod upward. The second piston compresses air and drives the first piston to move, causing the fourth pawl to disengage from the fourth ratchet. At this time, the second counterweight slides down the slide plate quickly under the action of gravity. The pull rope drives the take-up reel to rotate clockwise at high speed. The high speed is then transmitted to the generator input end through the overrunning clutch to generate electricity. This realizes a concentrated and rapid energy conversion mode, enabling the original low speed and small torque input to drive the generator to generate electricity efficiently in a short time, effectively improving the energy conversion efficiency.

[0018] 7. In this invention, the electrical energy generated by the generator and the electrical energy generated by the photovoltaic panel are combined into the same energy storage device, realizing dual-mode complementary energy storage of photovoltaic power generation on sunny days and rainwater power generation on rainy days. This significantly improves the energy self-sufficiency capability of the non-structural energy storage device under all-weather conditions and makes up for the shortcomings of existing devices that cannot effectively supplement electrical energy in cloudy and rainy weather.

[0019] 8. Without adding a complex electronic control system, this device achieves automatic collection, reciprocating triggering, slow energy storage, rapid release and power generation of rainwater energy through a purely mechanical mechanism, and shares energy storage with the photovoltaic system. This solves the problem that existing low-carbon building non-structural component energy storage devices rely solely on photovoltaic power generation and cannot effectively supplement electricity during cloudy and rainy weather, thus improving the device's climate adaptability and comprehensive utilization rate.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-19This invention provides a technical solution for a low-carbon building non-structural component energy storage device, comprising: a housing 1, a photovoltaic panel 2, a water collection tank 3, a blocking mechanism 4, a power mechanism 5, a unidirectional output mechanism 6, an anti-rotation mechanism 7, an energy conversion mechanism 8, a water outlet 9, a shading groove 10, a power rod 11, an output rod 12, a rotary joint 13, and a generator 14. A drainage trough is provided at the bottom of the housing 1, which serves as the supporting and protective shell for the entire device. The drainage trough at its bottom is used to drain rainwater after it has performed its work, preventing water accumulation. The photovoltaic panel 2 is located on the top left side of the housing 1. The photovoltaic panel 2 is existing technology and will not be described in detail here. The photovoltaic panel 2 is used to receive sunlight under sunny conditions and perform photoelectric conversion to store electrical energy in the energy storage unit. In the solar energy utilization, the water collection tank 3 is located on the top right side of the housing 1. The bottom end of the water collection tank 3 extends into the inner cavity of the housing 1. An outlet 9, connected to the inner cavity, is located at the center of the bottom end of the water collection tank 3. A through-hole shading groove 10 is located at the bottom front side of the water collection tank 3. The water collection tank 3 is used to collect rainwater flowing from the surface and surrounding area of ​​the photovoltaic panel 2 during rainy days. The outlet 9 at its bottom end guides the rainwater into the device. The shading groove 10 at the front provides installation and movement space for the blocking mechanism 4. The power rod 11 is rotatably mounted on the front right side of the inner cavity of the housing 1 via a bearing. The power rod 11 is the intermediate shaft for power transmission, transmitting the reciprocating rotational motion of the rack and pinion mechanism to the one-way output mechanism 6. 2. A bearing is rotatably mounted on the rear right end of the inner cavity of housing 1. Output rod 12 is the final power output shaft, transmitting the unidirectional rotational motion converted by unidirectional output mechanism 6 to energy conversion mechanism 8. Rotary joint 13 is located on the rear side of the inner cavity of housing 1, and is sleeved on the outer wall of output rod 12. The inner wall of rotary joint 13 and the outer wall of output rod 12 are clearance-fitted. Rotary joint 13 is existing technology and will not be described in detail here. Rotary joint 13 is used to achieve air circuit connection while output rod 12 rotates, transmitting the compressed air generated by second piston cylinder 8381 to first piston cylinder 86. Generator 14 is screwed to the rear side of the inner cavity of housing 1. The position of generator 14 corresponds to the position of output rod 12. 4 is existing technology and will not be elaborated further. It is used to receive high-speed rotational mechanical energy from energy conversion mechanism 8, convert it into electrical energy, and store it. The blocking mechanism 4 is set at the bottom of the water collection tank 3. When the power rod 11 rotates clockwise, the blocking mechanism 4 can separate the water outlet 9 from the inner cavity of the water collection tank 3. When the power rod 11 rotates counterclockwise, the blocking mechanism 4 no longer blocks the water outlet 9, causing the water outlet 9 to reconnect with the inner cavity of the water collection tank 3, thereby realizing the automatic opening and closing control of rainwater input. The power mechanism 5 is sleeved on the outer wall of the power rod 11. The power mechanism 5 is used to collect the weight of rainwater and use gravity to drive the rack 54 to reciprocate, which in turn drives the power rod 11 to rotate alternately clockwise and counterclockwise through the gear 510.A one-way output mechanism 6 is sleeved on the front side of the outer wall of the output rod 12. This mechanism converts the bidirectional rotational input of the power rod 11 into a one-way counterclockwise rotational output of the output rod 12. An anti-rotation mechanism 7 is sleeved on the middle of the outer wall of the output rod 12. This mechanism prevents the output rod 12 from rotating clockwise and from rotating back clockwise under the gravity of the second counterweight 837, ensuring that the output rod 12 can only rotate counterclockwise during energy accumulation. An energy conversion mechanism 8 is sleeved on the rear side of the outer wall of the output rod 12. This mechanism converts the slow counterclockwise rotation of the output rod 12 into the slow upward energy storage of the second counterweight 837, and then rapidly releases the energy after storage, driving the generator 14 to rotate at high speed to generate electricity.

[0024] As a preferred embodiment, the blocking mechanism 4 further includes: a screw 41, a sealing plate 42, a pulley 43, and a belt 44. The screw 41 is rotatably mounted at the bottom end of the water collection tank 3 via bearings. The screw 41 rotatably passes through the inner cavity of the blocking groove 10. The screw 41 acts as a transmission element, converting the rotational motion input by the pulley 43 into axial thrust, driving the sealing plate 42 to move back and forth along the blocking groove 10. The sealing plate 42 is slidably fitted into the inner cavity of the blocking groove 10. The sealing plate 42 is screwed to the outer wall of the screw 41. The sealing plate 42 is used to move back and forth under the drive of the screw 41, and when moving forward, it closes the water outlet 9 to stop the water supply. When reversing, the outlet 9 is opened to restore water supply, realizing the on / off control of rainwater input. There are two pulleys 43. The two pulleys 43 are respectively sleeved on the front side of the outer wall of the screw 41 and the front side of the outer wall of the power rod 11, and locked. The pulleys 43 are existing technology and will not be described in detail here. The pulleys 43 are power transmission components that synchronously transmit the rotational motion of the power rod 11 to the screw 41. The two ends of the belt 44 are respectively sleeved on the outer walls of the two pulleys 43. The belt 44 is used to realize flexible transmission between the power rod 11 and the screw 41, ensuring that the screw 41 can rotate synchronously in the same direction when the power rod 11 rotates clockwise or counterclockwise.

[0025] As a preferred embodiment, the power mechanism 5 further includes: a guide rail 51, a first slot 52, a slider 53, a rack 54, a groove 55, a pressing groove 56, a first spring 57, a first locking ball 58, a water storage component 59, a gear 510, and a first counterweight 511. There are two guide rails 51, both located at the bottom right center of the inner cavity of the housing 1, on the left and right sides of the power rod 11. Each guide rail 51 has a first slot 52 at its bottom left and right sides. The guide rail 51 provides vertical guidance and limiting support for the two racks 54. The first slots 52 at their bottom left and right sides cooperate with the first locking ball 58 to lock the position of the racks 54. There are four sliders 53. Four sliders 53 are respectively disposed on the front and rear sides of the inner cavity of the two guide rails 51. The sliders 53 are used to limit the front and rear displacement of the rack 54, ensuring that the rack 54 can only slide smoothly in the vertical direction. There are two racks 54, which are slidably fitted into the upper and lower sides of the inner cavity of the two guide rails 51. The front and rear sides of the rack 54 are provided with grooves 55 in the vertical direction. The sliders 53 are slidably fitted into the inner cavity of the grooves 55. The bottom ends of the left and right sides of the rack 54 are provided with squeezing grooves 56. The rack 54 is used to convert the gravity of the rainwater collected by the water cup 591 into linear reciprocating motion, and drives the power rod 11 to rotate through the gear 510. The first spring 57 is embedded in the inner cavity of the squeezing groove 56. One end of the first spring 57 The first spring 57 is a rotary spring that is elastically deformed after being compressed or stretched by an external force and returns to its initial state after the external force is removed. The first spring 57 provides continuous radial elastic force to the first locking ball 58, so that the first locking ball 58 can automatically lock into the first locking groove 52 when it reaches the position. A part of the first locking ball 58 is slidably fitted into the inner cavity of the compression groove 56, and the other end of the first spring 57 is fitted into the outer wall of the first locking ball 58. The position of the first locking ball 58 corresponds to and matches the position of the first locking groove 52. The two first locking balls 58 on the left side are fitted into the inner cavity of the first locking groove 52 corresponding to their positions. The length of the first locking ball 58 extending into the inner cavity of the first locking groove 52 is [not specified]. Smaller than its radius, the first locking ball 58 is used to engage with the first locking groove 52 to lock the position of the rack 54, and can disengage from the first locking groove 52 when subjected to sufficient external force. The water storage component 59 is located at the top of the right rack 54. The water storage component 59 is used to collect rainwater flowing from the outlet 9. As the water volume increases, the weight of the right rack 54 increases, thereby driving the right rack 54 to move downward.

When it rotates counterclockwise, it idles, ensuring that the generator 14 is only driven when the counterweight falls rapidly. The fourth ratchet 84 is located on the front side of the take-up reel 81. The ratchet 84 is used to drive the take-up reel 81 to rotate counterclockwise to take in the line when the output rod 12 rotates counterclockwise via the fourth pawl 89. When the fourth pawl 89 disengages, it allows the take-up reel 81 to rotate freely clockwise to let out the line.

The bottom end of the inner cavity of the first piston cylinder 86 is connected to the rotary joint 13 through a pipeline. The first piston cylinder 86 is used to accommodate the first piston 87. When compressed air enters through the pipeline, it pushes the first piston 87 to move upward. The piston 87 is slidably fitted into the bottom end of the inner cavity of the first piston cylinder 86. The first piston 87 is used to convert the pressure change in the air passage into mechanical displacement, which drives the fourth pawl 89 to move up and down through the connecting rod 88, controlling the engagement and disengagement of the fourth pawl 89 with the fourth ratchet 84. The top end of the connecting rod 88 is located at the middle of the bottom end of the first piston 87, and the bottom end of the connecting rod 88 extends slidably into the inner cavity of the second pawl seat 85.

The fourth pawl 89 is used to engage with the fourth ratchet 84 under the action of the fifth spring 810.When the output rod 12 rotates counterclockwise, it drives the take-up reel 81 to take in the line. When disengaged under air pressure, the take-up reel 81 is allowed to rotate freely to release the line. The fifth spring 810 is sleeved on the outer wall of the connecting rod 88. The bottom end of the fifth spring 810 is engaged with the top end of the fourth pawl 89, and the top end of the fifth spring 810 is engaged with the top end of the inner cavity of the second pawl seat 85. The fifth spring 810 is a rotary spring. It undergoes elastic deformation after being compressed or stretched by external force and returns to its initial state after the external force is removed. The fifth spring 810 is used to provide a continuous elastic thrust for the fourth pawl 89, so that the fourth pawl 89 remains engaged with the fourth ratchet 84 when there is no air pressure. The energy storage component 83 is located at the bottom end of the inner cavity of the housing 1. The energy storage component 83 is used to convert the slow rotation of the output rod 12 into the slow upward potential energy of the second counterweight 837 for storage, and to release it quickly after the energy storage is completed, driving the take-up reel 81 to rotate at high speed to generate electricity.

[0030] As a preferred embodiment, the energy storage component 83 further includes: a pull rope 831, a sliding plate 832, a moving groove 833, a second slot 834, a guide rod 835, a pulley 836, a second counterweight 837, and a release unit 838. One end of the pull rope 831 is disposed on the outer wall of the take-up reel 81. The pull rope 831 is used to wind and take up the line when the take-up reel 81 rotates counterclockwise and to pull the second counterweight 837 upward. When the second counterweight 837 slides down rapidly, it drives the take-up reel 81 to rotate clockwise. The sliding plate 832 is disposed at the bottom of the inner cavity of the housing 1 along an inclined direction. The other end of the pull rope 831 extends slidably into the inner cavity of the sliding plate 832. The inner cavity has movable grooves 833 on both the upper and lower sides along the vertical direction at its bottom. The bottom of the sliding plate 832 has two second slots 834 along the vertical direction. The distance between the two second slots 834 is the same as the distance between the upper and lower sides of the inner cavity of the movable groove 833. The sliding plate 832 provides a track for the second counterweight 837 to slide at an angle, allowing the second counterweight 837 to slide automatically down the inclined direction under gravity. The movable grooves 833 at the bottom of its inner cavity provide movement space for the pull rod 8382. The two second slots 834 at the bottom cooperate with the positioning block 8384 to lock the position of the pull rod 8382. The number of guide rods 835 is two. Two guide rods 835 are respectively located at the upper and lower ends of the upper and lower sides and the front and rear ends of the inner cavity of the slide plate 832. The guide rods 835 are used to pass through the second counterweight 837, providing guidance for the sliding of the second counterweight 837 and preventing the second counterweight 837 from tilting or getting stuck during movement. A pulley 836 is located at the top of the slide plate 832, and a pull rope 831 is attached to the outer wall of the pulley 836. The pulley 836 is used to change the traction direction of the pull rope 831, converting the rotation of the take-up reel 81 into a linear upward pull on the second counterweight 837. The second counterweight 837 is slidably fitted into the bottom end of the inner cavity of the slide plate 832. 7. A sliding mating device is attached to the outer wall of the guide rod 835. The other end of the pull rope 831 is located at the top of the second counterweight 837. The second counterweight 837 is an intermediate storage medium for mechanical energy. It is slowly pulled up to accumulate potential energy when the take-up reel 81 takes up the rope. When the release unit is disengaged, it slides down quickly to release the potential energy. The pull rope 831 drives the take-up reel 81 to rotate at high speed. The release unit 838 is located at the bottom of the slide plate 832. The release unit 838 is triggered when the second counterweight 837 is pulled up to the top of the slide plate 832. The fourth pawl 89 is disengaged from the fourth ratchet 84 by pneumatic means, thereby releasing the second counterweight 837 so that it slides down quickly.

[0031] As a preferred embodiment, the release unit 838 further includes: a second piston cylinder 8381, a pull rod 8382, a second piston 8383, a positioning block 8384, a sixth spring 8385, and a second locking ball 8386. The second piston cylinder 8381 is located at the center of the bottom end of the slide plate 832. The top end of the inner cavity of the second piston cylinder 8381 is connected to the rotary joint 13 through a pipe. The second piston cylinder 8381 is used to accommodate the second piston 8383. When the second piston 8383 moves upward, it presses the air inside the cylinder through the pipe towards the first piston cylinder 86, realizing the long-distance transmission of pneumatic signals. The pull rod 8382 is slidably and compatiblely inserted into the bottom end of the slide plate 832. The lower ends of the pull rod 8382 are slidably fitted into the bottom of the inner cavity of the two moving slots 833. Both the upper and lower ends of the pull rod 8382 extend slidably into the inner cavity of the slide plate 832. The pull rod 8382 is the transmission component of the trigger element. When the second counterweight 837 moves to the top of the slide plate 832, it pushes the pull rod 8382 upwards. When the second counterweight 837 slides down to the bottom, it pushes the pull rod 8382 downwards to reset. The second piston 8383 is located in the middle of the outer wall of the pull rod 8382. The second piston 8383 is slidably fitted into the bottom of the inner cavity of the second piston cylinder 8381. The second piston 8383 is used to convert the mechanical displacement of the pull rod 8382 into a change in air pressure; when it moves upwards, it compresses air. When the rod moves downward, air is drawn in. Positioning block 8384 is located on the outer wall of pull rod 8382. The position of positioning block 8384 corresponds to the position of the second slot 834 located below. Positioning block 8384 is used to install the sixth spring 8385 and the second locking ball 8386. When pull rod 8382 moves into position, it cooperates with the second slot 834 to achieve position locking. The sixth spring 8385 is embedded in the inner cavity of positioning block 8384, with one end of the sixth spring 8385 engaged with the inner wall of positioning block 8384. The sixth spring 8385 is a rotary spring; it undergoes elastic deformation after being compressed or stretched by external force and returns to its initial state after the external force is removed. The sixth spring 8385 is used to mount the second locking ball 8386. 386 provides continuous radial elastic force, enabling the second locking ball 8386 to automatically engage when it reaches the position of the second locking slot 834. A portion of the second locking ball 8386 is slidably adapted to be inserted into the inner cavity of the positioning block 8384, and another portion of the second locking ball 8386 is adapted to extend into the inner cavity of the lower second locking slot 834. The other end of the sixth spring 8385 is engaged with the outer wall of the second locking ball 8386. The length of the second locking ball 8386 extending into the inner cavity of the second locking slot 834 is less than its radius. The second locking ball 8386 is used to cooperate with the second locking slot 834 to lock the position of the pull rod 8382, and can disengage from the second locking slot 834 when subjected to sufficient axial thrust.

[0032] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0033] Step 1: Place this device on the roof of a low-carbon building. On sunny days, the photovoltaic panel 2 collects sunlight to convert and store electrical energy. On rainy days, when there is no sun, rainwater drips onto the photovoltaic panel 2. Since the photovoltaic panel 2 is tilted, the rainwater will flow to the right under gravity until it flows into the inner cavity of the water collection tank 3. Then, it flows through the outlet 9 into the inner cavity of the water cup 591, where the rainwater can be collected. Step 2: When a certain amount of rainwater is stored in the water cup 591, the weight of the water cup 591 increases due to the rainwater. Once the gravity generated by the weight of the water cup 591 exceeds the combined force of the weight of the first counterweight 511 and the preload of the first spring 57, the gravity of the water cup 591 will press the rack 54 on the right side to move downwards, thereby driving the gear 510 to rotate clockwise. The clockwise rotation of the gear 510 will drive the power rod 11 to rotate clockwise. At the same time, the gear 510 will cause the rack 54 on the left side to move upwards, thereby using the first slot 52 to squeeze the first ball 58 into the inner cavity of the squeezing groove 56, and squeeze the first spring 57 to undergo elastic deformation until the first ball 58 disengages from the inner cavity of the first slot 52. As the rack 54 on the right side moves downwards, it will drive the water cup 591 and the shielding cylinder 593 to move downwards. During the downward movement of the shielding cylinder 593, the cooperation between the spiral groove 597 and the sliding column 595 will be utilized. This causes the shielding cylinder 593 to rotate. When the rack 54 on the right side moves to the bottom of the inner cavity of the guide rail 51, the inner wall of the guide rail 51 can press the first locking ball 58 on the rack 54 into the inner cavity of the pressing groove 56, and compress the first spring 57 to undergo elastic deformation. When the first locking ball 58 moves to the position of the first locking groove 52, the elastic force of the first spring 57 can push the first locking ball 58 to move into the first locking groove 52 corresponding to its position. Inside the cavity, at this time, the bottom end of the water cup 591 moves out of the bottom end of the inner cavity of the first sleeve 596, and under the cooperation between the sliding column 595 and the spiral groove 597, the shielding cylinder 593 is rotated 180 degrees. At this time, the first drain outlet 592 and the second drain outlet 594 overlap, which can cause the rainwater in the water cup 591 to be discharged from the inner cavity of the water cup 591 through the first drain outlet 592 and the second drain outlet 594, and the rainwater is discharged from the inner cavity of the box 1 through the drainage groove opened at the bottom of the box 1. Step 3: As the rack 54 on the right moves downward, the gear 510 drives the power rod 11 to rotate clockwise. This allows the pulley 43 and belt 44 to rotate the screw 41. The rotational force generated by the screw 41 causes the sealing plate 42 to move backward until the sealing plate 42 separates the outlet 9 from the inner cavity of the water collection tank 3, thus preventing rainwater from continuing to flow into the inner cavity of the water cup 591. Step 4: Rotating the power rod 11 clockwise will drive the first bevel gear 61 to rotate clockwise. Rotating the first bevel gear 61 clockwise will drive the third bevel gear 67 to rotate counterclockwise through the second bevel gear 66. Rotating the third bevel gear 67 counterclockwise will drive the output rod 12 to rotate counterclockwise through the cooperation between the second pawl 69 and the second ratchet 610. At the same time, rotating the first bevel gear 61 clockwise will cause the first ratchet 64 to squeeze the first pawl 63, causing the first pawl 63 to move into the inner cavity of the first bevel gear 61 and squeeze the second spring 62 to undergo elastic deformation. Step 5: Rotating the output rod 12 counterclockwise will cause the second pawl seat 85 to drive the fourth pawl 89 to rotate counterclockwise. The fourth pawl 89, when rotated counterclockwise, will cooperate with the fourth ratchet 84 to drive the take-up reel 81 to rotate counterclockwise. The counterclockwise rotation of the take-up reel 81 will cause the pull rope 831 to wind around its outer wall. Thus, the pull rope 831 can be used to pull the second counterweight 837 to move upward along the inner cavity of the slide plate 832. The counterclockwise rotation of the take-up reel 81 will drive the second sleeve 82 to rotate counterclockwise. The counterclockwise rotation of the second sleeve 82, using the action of the overrunning clutch 811, will cause the second sleeve 82 to idle, and the input and output ends of the generator 14 will not rotate. Step 6: Rotating the output rod 12 counterclockwise will drive the third ratchet 71 to rotate counterclockwise. Rotating the third ratchet 71 counterclockwise will push the third pawl 74 to move into the inner cavity of the first pawl seat 72 and compress the fourth spring 73 to cause elastic deformation. Thus, the cooperation between the third pawl 74 and the third ratchet 71 can be used to prevent the output rod 12 from rotating clockwise under the action of the second counterweight 837. Step 7: After the water in the inner cavity of the water cup 591 is drained, the weight of the water cup 591 decreases. At this time, the weight of the first counterweight 511 is greater than the combined force of the weight of the water cup 591 and the preload of the first spring 57. Under the action of the first counterweight 511, the rack 54 on the left side moves downward, which in turn causes the rack 54 on the right side to move the water cup 591 upward. During the upward movement of the water cup 591, the cooperation between the spiral groove 597 and the sliding column 595 causes the blocking cylinder 593 to rotate in the opposite direction until the blocking cylinder 593 rotates to the initial position. At this time, the first drain outlet 592 can be opened. The inner cavity is blocked, thus moving in the opposite direction to step two above, until both racks 54 return to their initial positions. As the rack 54 on the left moves downward, it causes the gear 510 to drive the power rod 11 to rotate counterclockwise. The counterclockwise rotation of the power rod 11 can use the cooperation between the pulley 43 and the belt 44 to cause the screw 41 to rotate in the opposite direction. The rotational force generated by the rotation of the screw 41 causes the sealing plate 42 to move forward, causing the water outlet 9 and the inner cavity of the water collection tank 3 to reconnect, so that rainwater can continue to flow into the inner cavity of the water cup 591 through the water outlet 9. Step 8: Rotating the power rod 11 counterclockwise will drive the first bevel gear 61 to rotate counterclockwise. The first bevel gear 61, when rotated counterclockwise, will drive the output rod 12 to rotate counterclockwise through the cooperation between the first pawl 63 and the first ratchet 64. At the same time, the first bevel gear 61, when rotated counterclockwise, will drive the third bevel gear 67 to rotate clockwise through the second bevel gear 66. When the output rod 12 rotates counterclockwise and the third bevel gear 67 rotates clockwise, the third bevel gear 67 will idle on the outer wall of the output rod 12. The second ratchet 610 will push the second pawl 69 to move into the inner cavity of the third bevel gear 67 and compress the third spring 68 to cause elastic deformation. The output rod 12, when rotated counterclockwise, will repeat the actions of steps 5 and 6 above. Step Nine: As the second counterweight 837 moves upward, after it contacts the top of the pull rod 8382, its continued upward movement pushes the pull rod 8382 upward. The upward movement of the pull rod 8382 then moves the positioning block 8384 and the second piston 8383 upward. The upward movement of the positioning block 8384 utilizes the second slot 834 to compress the second ball 8386, causing it to move into the inner cavity of the positioning block 8384 and compressing the sixth spring 8385, resulting in elastic deformation. This continues until the second ball 8386 disengages from the inner cavity of the second slot 834, and the second piston 8383 moves along the second piston cylinder 83... The upward movement of the inner cavity of piston 81 compresses the air at the top of the inner cavity of the second piston cylinder 8381, which flows through the pipe and rotary joint 13 into the inner cavity of the first piston cylinder 86. Under the action of air pressure, the first piston 87 is pushed upward via the connecting rod 88, causing the fourth pawl 89 to move upward and compressing the fifth spring 810, resulting in elastic deformation. As the pull rod 8382 moves upward, and the positioning block 8384 moves the second locking ball 8386 to the position of the upper second locking groove 834, the elastic force of the sixth spring 8385 pushes the second locking ball 8386 into the inner cavity of the upper second locking groove 834. With the position of the pull rod 8382 fixed, the air pressure generated by the second piston 8383 causes the first piston 87 to move the fourth pawl 89 upwards until it separates from the fourth ratchet 84. Then, under the weight of the second counterweight 837, it slides downwards along the inner cavity of the slide plate 832. This allows the pull rope 831 to pull the take-up reel 81 clockwise. The clockwise rotation of the take-up reel 81 causes the second sleeve 82 to rotate clockwise. The torque generated by the clockwise rotation of the second sleeve 82 is transmitted to the input end of the generator 14 via the overrunning clutch 811, thereby utilizing the generator... The machine 14 generates electricity. When the second counterweight 837 moves to the bottom of the inner cavity of the slide plate 832, the second counterweight 837 contacts the bottom end of the pull rod 8382. The second counterweight 837 can push the pull rod 8382 downward, which in turn drives the second piston 8383 and the positioning block 8384 downward. The downward movement of the second piston 8383 causes the air in the inner cavity of the first piston cylinder 86 to flow back into the inner cavity of the second piston cylinder 8381. Under the elastic force of the fifth spring 810, the fourth pawl 89 is pushed back to the initial position, and the above actions can be repeated to collect electrical energy again.

[0034] Without adding a complex electronic control system, this device achieves automatic collection, reciprocating triggering, slow energy storage, rapid release and power generation of rainwater energy through a purely mechanical mechanism, and shares energy storage with the photovoltaic system. This solves the problem that existing low-carbon building non-structural component energy storage devices rely solely on photovoltaic power generation and cannot effectively supplement electricity during rainy weather, thus improving the device's climate adaptability and comprehensive utilization rate.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
