Description

Technical Field

[0001] This invention relates to the field of integrated photovoltaic and energy storage cabinet technology, and in particular to an off-grid integrated photovoltaic and energy storage device. Background Technology

[0002] Off-grid integrated photovoltaic-storage energy storage equipment is a comprehensive energy equipment that operates independently from the public power grid. Its core components include solar photovoltaic modules, energy storage battery packs, a PCS bidirectional converter, and an intelligent control system, enabling autonomous closed-loop operation of power generation, energy storage, and power supply. It captures solar energy through photovoltaic modules and converts it into electricity, part of which is directly supplied to end-user loads, while the remaining electricity is stored in the energy storage unit. During periods of insufficient sunlight or peak load, the electricity is released, dynamically balancing supply and demand to ensure stable power supply.

[0003] Existing energy storage cabinets require dehumidification devices to prevent the internal humid environment from damaging electrical components and affecting operational stability. However, these dehumidification devices have inherent flaws. Because the condensate is not completely clean, it carries dust from the air inside the cabinet, trace metal fragments generated by the operation of electrical components, and soluble impurities during its formation. These impurities adhere to and deposit on the slope of the drain plate after entering the drain tank with the condensate. Although the slope plate can guide the water flow, the slow water flow allows the impurities to gradually form a scale layer, which not only reduces the slope's guiding efficiency but may also lead to localized condensate accumulation. At the same time, the drain pipe opening and inner wall are more prone to scale accumulation due to the weak scouring force of the water flow. Over time, this can easily cause blockage of the drain channel, preventing the condensate from draining smoothly and causing it to flow back into the cabinet. This not only undermines the dehumidification effect but may also corrode and damage electrical components, affecting the overall operational reliability of the energy storage cabinet.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides an integrated off-grid energy storage device to solve the problem that the dehumidification device of the energy storage cabinet is prone to scale buildup and blockage due to impurities in the condensate, and the backflow of condensate corrodes the components, affecting the dehumidification effect and operational reliability.

The condensing unit is supported and connected to the bottom of the inner wall of the water storage tank via the support frame, and the condensing unit is located in the center of the water storage tank, with gaps left between it and the sides and bottom of the water storage tank. The top cover is located above the water storage tank, which not only protects the condensing unit but also leaves a gap between it and the top of the water storage tank for airflow. Multiple sets of drain pipes are connected to one side of the bottom of the water storage tank, and the multiple sets of drain pipes are interconnected through a connecting pipe, with one end of the connecting pipe penetrating through the integrated photovoltaic storage cabinet. An air supply unit is configured on the water storage tank to blow the air cooled by the condensing unit into the integrated photovoltaic storage cabinet.

[0008] Furthermore, the air supply unit includes an exhaust end embedded in the side of the water storage tank, which is arranged at a right angle; multiple sets of axial fans are provided and arranged opposite to the air inlet port of the exhaust end, one end of the multiple sets of axial fans is connected to an air collecting hood, one side of the air collecting hood is connected to an air inlet pipe, and the free end of the air inlet pipe passes through the integrated light and energy storage cabinet.

[0009] Furthermore, the inner wall of the water storage tank is provided with a U-shaped groove on both sides. The U-shaped groove is composed of a horizontal slide and an arched slide connected together. The scraping component includes a concave frame. Both sides of the concave frame are provided with a slider that is embedded and slides in the horizontal slide. The concave frame is initially located in the water storage tank near the right side through the slider. A step is provided at the connection between one end of the horizontal slide and the arched slide.

[0010] Furthermore, the concave frame is provided with an inclined scraper, and multiple sets of friction rods, the same number as the drain pipes, are horizontally arranged on the concave frame. The friction rods are adapted to contact friction wheels, and a rotating shaft is fixed at the center of the friction wheel. A rotating ring is connected to the rotating shaft by a bearing. Vertically downward scraper rods are symmetrically arranged on the surface of the rotating ring. The scraper rods are in contact with the inner wall of the drain pipe end. Multiple sets of rotating rings are connected to a mounting frame. The mounting frame is fixed to the inner wall of the water storage tank and is located below the condensation unit.

[0011] Furthermore, the moving component includes a horizontally arranged fixed rack, which is fixed to the outer side of the water storage tank near the center. A movable gear meshes on the fixed rack, and a movable rack symmetrical to the fixed rack meshes on the movable gear.

A concave frame of the scraping component drives an inclined scraper to reciprocate along a U-shaped groove, efficiently removing dust, metal debris, and other impurities deposited at the bottom of the water tank, preventing scale buildup that could affect flow efficiency and cause localized sludge accumulation. Simultaneously, the movement of the concave frame, through the linkage of a friction rod and a friction wheel, drives the scraper to rotate and remove scale and impurities adhering to the inner wall of the drain pipe, completely eliminating the risk of drainage blockage and preventing condensate backflow from corroding electrical components. The multi-stage speed reduction and power reuse design of the drive component ensures smooth and controllable scraping and cleaning actions while simultaneously driving an axial fan for efficient dehumidification and cooling. Combined with the flexible connection and optimized reciprocating stroke of the moving component, this further enhances the continuity and durability of the device's operation.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-5 As shown, the present invention provides an integrated photovoltaic-storage off-grid energy storage device, including a photovoltaic-storage integrated cabinet 1, a dehumidification component 2, a scraping component 5, a drive component 3, and a moving component 4. The photovoltaic-storage integrated cabinet 1 is equipped with a dehumidification component 2, which is equipped with an axial flow fan 25 that can blow condensed air into the photovoltaic-storage integrated cabinet 1 and a water storage tank 21 for receiving condensate. The water storage tank 21 is equipped with a condensation unit 29 for dehumidification. The scraping component 5 is located at the bottom of the water storage tank 21 and is used to scrape off condensate. The scraping component 5 is located below the condensation unit 29 and is suitable for scraping off the condensate at the bottom of the water storage tank 21. It can also clean the scale and other impurities on the inner wall of the drainage channel at the same time. The scraping component 5 is powered by the drive component 3. The drive component 3 provides reciprocating force to the scraping component 5 through the moving component 4. In the process of power transmission, the speed reduction and reciprocating stroke are optimized, so that the scraping action is more suitable for the condensate cleaning needs in the dehumidification scenario.

[0022] In this invention, the dehumidification component 2 is mainly used to reduce the humidity inside the integrated photovoltaic storage cabinet 1, preventing the humid environment from corroding electrical components, and at the same time providing cooling airflow inside the cabinet to ensure the operational stability of the energy storage equipment. Preferably, the dehumidification component 2 includes a support frame 291 and a top cover 22. The condensing unit 29 is supported and connected to the bottom of the inner wall of the water storage tank 21 via the support frame 291, and is located at the center of the water storage tank 21. The condensing unit 29 is the core component for cooling and dehumidification, and can adopt an evaporator or heat exchange coil structure. It condenses water vapor by exchanging heat with the air inside the cabinet. Gaps are left around the water storage tank 21 and at the bottom, which facilitates the smooth dripping of condensed water to the bottom of the water storage tank 21 and allows airflow to fully pass over the surface of the condensing unit 29 for efficient heat exchange and dehumidification. The top cover 22 is located above the water storage tank 21, providing protection against dust and foreign object impacts to the condensing unit 29, and also providing a gap between it and the top of the water storage tank 21 for airflow, ensuring smooth air circulation. Multiple sets of drain pipes 241 are connected to the bottom of the water storage tank 21 near one side. The multiple sets of drain pipes 241 are interconnected through the connecting pipe 24 to form a centralized drainage channel. One end of the connecting pipe 24 passes through the integrated photovoltaic storage cabinet 1, which can quickly discharge the condensate collected in the water storage tank 21 to the outside of the cabinet. The water storage tank 21 is equipped with an air supply unit, which is used to blow the dry and cold air cooled by the condensation unit 29 evenly into the interior of the integrated photovoltaic storage cabinet 1, taking into account both dehumidification and cooling effects, and further optimizing the internal operating environment of the cabinet.

[0023] In this invention, the air supply unit is mainly used to form an airflow circulation path inside the integrated light and energy storage cabinet 1, guiding the dry, cold air after cooling and dehumidification by the condensation unit 29 to diffuse evenly to all areas of the cabinet. Simultaneously, it can accelerate the flow and replacement of hot and humid air inside the cabinet, ensuring full coverage of dehumidification and cooling effects. A preferred air supply unit includes an exhaust end 23 embedded in one side of the water storage tank 21. This exhaust end 23 is arranged at a right angle, and its bent structure adapts to the internal spatial layout of the cabinet, effectively changing the airflow direction and reducing wind resistance. Multiple axial fans 25 are provided and arranged corresponding to the air inlet ports of the exhaust end 23, forming a concentrated air supply force and improving the airflow output intensity. Multiple axial fans 25 are connected to a common air collection hood 26 at the end away from the exhaust end 23. The air collection hood 26 has an flared design, which can collect the humid and hot air inside the cabinet and guide it to the axial fans 25 and the condenser unit 29 to optimize the heat exchange and dehumidification efficiency. The side of the air collection hood 26 away from the axial fans 25 is sealed with an air inlet pipe 27. The free end of the air inlet pipe 27 is set through the side wall of the integrated light and energy storage cabinet 1, which can facilitate the introduction of clean air from outside the cabinet as a supplement, and can also achieve selective replacement of internal and external air as needed, further ensuring the cleanliness of the air inside the cabinet.

[0024] In actual use, during the operation of the integrated light and energy storage cabinet 1, the air supply unit starts first. Multiple sets of axial flow fans 25 gather the humid and hot air inside the cabinet through the air collector hood 26. At the same time, the air inlet pipe 27 can selectively introduce clean air from outside as a supplement. The airflow is pushed to the condensation unit 29 area by the axial flow fans 25. The condensation unit 29 fully exchanges heat with the airflow, causing the water vapor in the air to condense and precipitate, forming dry and cold air. Under the continuous power of the axial flow fans 25, the cold air is blown evenly to the cabinet after the airflow direction is changed by the right-angle exhaust end 23, so as to achieve dehumidification and cooling. The condensed water droplets drip down the surface of the condensation unit 29 and smoothly collect at the bottom of the water storage tank 21 through the gaps between the unit and the tank. Then, they flow through multiple sets of drain pipes 241 into the connecting pipe 24 and are finally quickly discharged to the outside through the connecting pipe 24 that runs through the cabinet, preventing water accumulation. The top cover 22 above the water storage tank 21 effectively prevents dust and foreign objects from entering the condensation unit 29, ensuring heat exchange efficiency and equipment cleanliness. The whole process forms a closed-loop operation of humid and hot air intake, condensation and dehumidification, dry cold air output, and centralized discharge of condensate, continuously providing a dry and stable operating environment for the internal electrical components of the integrated photovoltaic and energy storage cabinet 1, and preventing moisture corrosion from affecting the equipment's lifespan and operational safety.

[0025] Reference Figures 8-9 As shown, the scraping component 5 in this invention is mainly used to scrape and clean the condensate at the bottom of the water storage tank 21, preventing condensate residue or pipe blockage from affecting the operating efficiency of the dehumidification component 2. Preferably, the inner wall of the water storage tank 21 is provided with U-shaped grooves 201 on both sides. These U-shaped grooves 201 are composed of a horizontal slide groove and an arched slide groove connected together. The scraping component 5 includes a concave frame 51, with sliding balls (not shown) embedded and sliding within the horizontal slide groove on both sides of the concave frame 51. Figure 8 For example, the concave frame 51 is initially positioned near the right side of the water tank 21 via a slider. A step (not shown in the figure) is provided at the connection between one end of the horizontal slide and the arched slide. When the concave frame 51 initially slides to the connection between the horizontal slide and the arched slide via the slider, the slider passes over the step, and its reset movement can only move through the arched slide to one end of the horizontal slide, thus accurately returning to the initial position, realizing the reciprocating cycle of the scraping action and the position reset.

[0026] To further improve the thoroughness of condensate cleaning and simultaneously solve the problem of dirt blockage on the inner wall of drain pipe 241, a scraper 52 is provided in the concave frame 51. The scraper 52 can move back and forth with the concave frame 51 to efficiently scrape the condensate at the bottom of the water storage tank 21 towards the drainage area. Multiple sets of friction rods 54, the same number as the drain pipe 241, are horizontally arranged on the concave frame 51. Friction rods 54 are adapted to contact friction wheels 58. When the concave frame 51 moves to the designated position, the friction rods 54 and friction wheels 58 generate relative friction, driving the friction wheels 58 to rotate. A rotating shaft 57 is fixed at the center of the friction wheel 58. A rotating ring 56 is connected to the rotating shaft 57 by a bearing. Vertically downward scraper rods 561 are symmetrically arranged on the surface of the rotating ring 56. The scraper rods 561 are in contact with the inner wall of the drain pipe 241. When the rotating ring 56 rotates with the friction wheel 58, the scraper rods 561 can rotate and scrape away scale, impurities and other debris from the inner wall of the drain pipe 241. Multiple sets of rotating rings 56 are connected to a mounting bracket 55. The mounting bracket 55 is fixed to the inner wall of the water storage tank 21 and is located below the condensation unit 29. It provides stable installation support for the rotating rings 56 and the scraper rods 561, thereby achieving synchronous cleaning of the bottom of the water storage tank 21 and the inner wall of the drain pipe 241, ensuring the long-term unobstructed drainage of the dehumidification component 2.

[0027] In actual use, when the dehumidification component 2 is running continuously, condensate continuously accumulates at the bottom of the water storage tank 21. At this time, the drive component 3 starts and drives the concave frame 51 of the scraping component 5 to start moving through the moving component 4. The sliding balls on both sides of the concave frame 51 slide along the horizontal groove on the inner wall of the water storage tank 21, and the inclined scraper 52 moves to the left with the concave frame 51 (see reference). Figure 8 The condensate at the bottom of the water tank 21 is quickly scraped toward the drainage area. When the concave frame 51 slides to the connection between the horizontal slide and the arched slide, the sliding ball crosses the step and enters the arched slide. Then, under the action of power, it moves back along the arched slide and finally returns to one end of the horizontal slide through the arched slide, returning to the initial position close to the right, completing one scraping cycle. During this process, when the concave frame 51 approaches and moves to the left side of the water storage tank 21, the friction rod 54 on the concave frame 51 moves with the concave frame 51 and generates relative friction with the friction wheel 58, causing the friction wheel 58 to rotate. The friction wheel 58 drives the rotating ring 56 to rotate through the rotating shaft 57. The scraper 561 on the surface of the rotating ring 56 simultaneously rotates and scrapes away scale, impurities, etc. on the inner wall of the drain pipe 241. The mounting bracket 55 provides stable support for the rotating ring 56 and the scraper 561, ensuring that the scraping action is continuous and effective. This cycle repeats, and the scraping component 5 not only cleans the condensate at the bottom of the water storage tank 21 in a timely manner, but also cleans the dirt on the inner wall of the drain pipe 241 at the same time, effectively avoiding condensate residue or pipe blockage, ensuring the long-term unobstructed drainage path of the dehumidification component 2, and thus maintaining the stable and efficient operation of the dehumidification system inside the integrated photovoltaic storage cabinet 1.

[0028] Reference Figures 6-7 As shown, the moving component 4 in this invention is mainly used to convert the power of the driving component 3 into the reciprocating motion power of the scraping component 5, realizing the periodic reciprocating motion of the scraping component 5 in the water storage tank 21, ensuring the continuous scraping of condensate and cleaning of the drain pipe 241. Preferably, the moving component 4 includes a horizontally arranged fixed rack 41, which is fixed on the outer side of the water storage tank 21 near the center, providing a basic meshing structure for power transmission; a movable gear 42 meshes on the fixed rack 41, and a movable rack 43 symmetrical to the fixed rack 41 meshes on the movable gear 42. Through the meshing and linkage of the movable gear 42 with the fixed rack 41 and the movable rack 43, the rotational power is converted into linear reciprocating power; a sliding frame 44 is fixed on the movable rack 43 and slidably disposed on the end face of the water storage tank 21. The sliding frame 44 slides on the end face of the water storage tank 21 as the movable rack 43 moves, thereby driving the scraping component 5 to realize the reciprocating scraping action, ensuring the stability of power transmission and the accuracy of action.

[0029] To adapt to the movement trajectory of the scraping component 5 within the groove 201 and avoid structural jamming caused by rigid connection, a vertically movable connecting rod 45 is fixed to the side of the sliding frame 44, which passes through the concave frame 51. A support spring 451 is connected to the upper end face of the concave frame 51 via the connecting rod 45. When the concave frame 51 moves along the arched slide of the groove 201, the support spring 451 can compensate for the displacement change of the concave frame 51 through elastic extension and contraction. At the same time, it provides buffering and reset assistance when the concave frame 51 resets, ensuring smooth power transmission between the moving component 4 and the scraping component 5, and avoiding component wear or movement jamming caused by differences in movement trajectory.

[0030] In actual use, the rotational power output by the drive component 3 is transmitted to the movable gear 42. The movable gear 42 rotates under the meshing action with the fixed rack 41, and at the same time forms a linkage with the symmetrically arranged movable rack 43, converting the rotational power into the linear reciprocating motion of the movable rack 43. The movable rack 43 drives the fixedly connected sliding frame 44 to slide smoothly along the end face of the water storage tank 21. The sliding frame 44 transmits power to the concave frame 51 of the scraping component 5 through the connecting rod 45, driving the concave frame 51 to reciprocate synchronously with the sliding frame 44. When the concave frame 51 slides along the horizontal slide groove of the loop groove 201, the support spring 451 remains in a natural extension and contraction state to ensure smooth power transmission. When the concave frame 51 slides to the connection between the horizontal slide groove and the arched slide groove and moves along the arched slide groove, the concave frame 51 produces a vertical displacement change. At this time, the support spring 451 compensates for the displacement difference through elastic extension and contraction, avoiding rigid tension or jamming between the connecting rod 45 and the concave frame 51. After the concave frame 51 completes its scraping action and returns to its original position along the arched slide groove, the support spring 451 provides a reverse elastic assist, helping the concave frame 51 smoothly return to its initial position on the horizontal slide groove. Throughout the process, the moving component 4, through the cooperation of gear meshing and elastic connection, achieves stable power transmission and precise conversion of motion form, while also adapting to the special motion trajectory of the scraping component 5. This effectively avoids component jamming or wear, ensuring the continuous and efficient scraping of condensate and cleaning of the drain pipe 241 by the scraping component 5.

[0031] Reference Figures 5-7 As shown, in this invention, the drive component 3 is mainly used to provide stable and controllable power input to the moving component 4. By reducing speed and transmitting power, it ensures that the scraping action of the scraping component 5 is smooth and efficient, and avoids structural wear or poor cleaning effect due to improper power output. The preferred drive component 3 includes gears 5 (39), 4 (38), 3 (37), and 2 (36) that mesh in a series of inclined gears. Each gear is rotatably mounted on the side of the water tank 21 via bearings, ensuring flexibility during gear transmission and providing stable mounting support to prevent offset or shaking during transmission. During power transmission, the externally input rotational power first acts on the first gear 2 (36), and then is transmitted sequentially through the inclined meshing structure between the gears. Utilizing the meshing and deceleration characteristics of multiple sets of gears, the initial high-speed rotational power is gradually converted into low-speed, high-torque power output, achieving deceleration. This matches the power intensity required by the scraping component 5 to scrape condensate and clean the drain pipe 241, and provides a suitable power output rhythm for the scraping component 5, making the movements of the scraper 52 and scraper 561 smoother and more controllable, reducing impact wear between components, ensuring thorough cleaning, and extending the service life of the overall device.

[0032] To convert the unidirectional rotational power of the drive assembly 3 into the linear reciprocating power required by the moving assembly 4, and to further optimize the reciprocating stroke and coverage of the scraping assembly 5, a reciprocating unit is meshed on gear 2 36. This reciprocating unit includes a crank arm 1 310, which is fixed on the shaft of gear 5 39 and rotates synchronously with gear 5 39. One end of crank arm 1 310 is rotatably connected to crank arm 2 311 via a pin or other movable connecting component. The end of crank arm 2 311 away from crank arm 1 310 is fixedly connected to the movable gear 42 via a central shaft. When gear 5 39 drives crank arm 1 310 to make circular motion, the circular motion is converted into reciprocating swing and translation of movable gear 42 through the hinge linkage between crank arm 1 310 and crank arm 2 311. This drives movable gear 42 to make reciprocating meshing motion on fixed rack 41, which in turn drives movable rack 43 to make linear reciprocating motion with a stroke twice the swing radius of the crank arm. This expands the cleaning coverage of scraping component 5 and ensures the continuity and thoroughness of scraping action, making the cleaning of the bottom of water tank 21 and the inner wall of drain pipe 241 more efficient.

[0033] To achieve efficient multi-path utilization of the power of the drive component 3 and provide stable power to the axial flow fan 25 of the air supply unit simultaneously, reducing the need for additional power sources, a transmission unit is meshed on gear 2 36. This transmission unit includes a bracket 32 ​​fixed to the side of the water storage tank 21 by bolts. Gear 1 35 is rotatably mounted on the bracket 32 ​​via a gear shaft. Gear 1 35 meshes with gear 2 36 to ensure slip-free power transmission. A pulley 2 33 is fixed to the end of the gear shaft away from gear 1 35 via a key connection or other means. Pulley 2 33 is connected to pulley 1 31 via a belt body 34. Pulley 1 31 is fixed on the fan shaft of a set of axial flow fans 25. When the drive component 3 drives gear 2 36 to rotate, power is transmitted to the axial flow fan 25 sequentially through gear meshing and belt transmission, realizing synchronous power linkage between the axial flow fan 25 and the transmission unit. This simplifies the overall power system structure and allows the speed of the axial flow fan 25 to match the power output of the drive component 3, ensuring a stable air supply effect of the air supply unit.

[0034] Working principle: After the equipment starts, the power is input to the drive assembly 3 through the fan shaft of the axial fan 25. The second gear 36 of the drive assembly 3 achieves multi-stage speed reduction through the sequential tilting meshing of the second gear 36 with the third gear 37, the fourth gear 38, and the fifth gear 39. This converts the initial high-speed power into low-speed, high-torque power, which not only matches the action requirements of the scraping assembly 5 but also reduces the impact wear of the components. At the same time, the second gear 36 synchronously links the reciprocating unit and the transmission unit, realizing the efficient reuse of a single power source without the need for additional power devices, thus simplifying the overall structural complexity.

[0035] In the dehumidification and airflow circulation process, the transmission unit receives the rotational power of gear 2 36. Through the meshing of gear 1 35 and gear 2 36, it drives the gear shaft and the pulley 2 33 at the end to rotate synchronously. Then, it is transmitted to pulley 1 31 through belt body 34, and finally drives the axial flow fan 25 to start operation. The axial flow fan 25 collects the humid and hot air inside the photovoltaic storage cabinet 1 through the air collector hood 26. The air inlet pipe 27 can selectively introduce clean air from outside to supplement it. The airflow is pushed to the condensation unit 29 in the center of the water storage tank 21. The condensation unit 29 fully exchanges heat with the airflow, causing water vapor to condense and drip down the surface. With the help of the gaps between the condensation unit 29 and the water storage tank 21 around and at the bottom, it is collected at the bottom of the water storage tank 21. The dehumidified dry and cold air is then driven by the continuous thrust of the axial flow fan 25. The airflow direction is changed through the right-angle exhaust end 23, and it is evenly diffused into the photovoltaic storage cabinet 1 to achieve dehumidification and cooling.

[0036] In the condensate cleaning and drainage maintenance stage, the power of the drive component 3, after being reduced in speed, is converted into motion mode through the reciprocating unit. Gear 5 39 drives the crank arm 1 310 to make circular motion. Through the hinge linkage between the crank arm 1 310 and the crank arm 2 311, the circular motion is converted into the reciprocating meshing motion of the movable gear 42, which in turn drives the movable rack 43 to drive the sliding frame 44 to slide back and forth along the end face of the water storage tank 21 with double stroke. The sliding frame 44 transmits power to the concave frame 51 of the scraping component 5 through the connecting rod 45 and the support spring 451. The sliding balls on both sides of the concave frame 51 slide along the horizontal sliding groove of the loop groove 201. The inclined scraper 52 simultaneously scrapes the condensate at the bottom of the water storage tank 21 towards the area of ​​the drain pipe 241. The condensate flows into the connecting pipe 24 through the drain pipe 241 and is discharged from the cabinet. When the concave frame 51 slides to the point where the horizontal slide groove and the arched slide groove connect, the sliding ball crosses the step and returns to its original position along the arched slide groove. The support spring 451 compensates for the vertical displacement difference through elastic expansion and contraction, preventing structural jamming. Simultaneously, when the concave frame 51 moves to the left side of the water storage tank 21, the friction rod 54 and the friction wheel 58 generate relative friction, driving the rotating shaft 57, rotating ring 56, and scraper 561 to rotate, scraping away scale and impurities from the inner wall of the drain pipe 241. The mounting frame 55 provides stable support for this structure. The entire process ensures the continuous operation of the dehumidification component 2, providing a dry and stable operating environment for the internal electrical components of the integrated photovoltaic and energy storage cabinet 1.
