[0002] A new energy photovoltaic energy storage power station is an integrated energy system that combines solar photovoltaic power generation with an energy storage system. It aims to improve energy utilization efficiency and power supply stability, compensating for the inherent intermittency and volatility of photovoltaic power generation. Its working principle is to generate electricity using solar energy, storing surplus electricity during periods of ample sunlight for use at night or during cloudy / rainy weather, ensuring a continuous and reliable energy supply.

[0003] Existing photovoltaic energy storage power stations typically deploy energy storage boxes extensively outdoors. These boxes are constantly exposed to the natural open environment and are susceptible to various weather conditions, leading to the accumulation of various deposits on their surfaces: snow accumulates in snowy weather, water accumulates in rainy weather, and dust accumulates in windy and sandy weather. If not cleaned and maintained in a timely manner, several safety hazards arise: thick snow can block ventilation channels, hindering heat dissipation and potentially causing overheating; water can easily seep into the electrical components, causing short circuits and corrosion, while also eroding the outer shell and mechanical structure, accelerating material aging and rust; surface dust significantly reduces heat dissipation efficiency, easily causing overheating under high-temperature conditions and affecting the safe and stable operation of the energy storage box.

[0004] Therefore, current energy storage boxes are susceptible to dust, snow, water, and ice accumulation, which can lead to problems such as impaired heat dissipation, overheating, and electrical short circuits.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] A new energy photovoltaic energy storage power station is an integrated energy system that combines solar photovoltaic power generation with an energy storage system. Its working principle is to generate electricity using solar energy, storing surplus electricity during periods of ample sunlight for use at night or during cloudy / rainy weather, ensuring a continuous and reliable energy supply. Currently, energy storage boxes are susceptible to dust, snow, water accumulation, and ice buildup, which can lead to problems such as impaired heat dissipation, overheating, and electrical short circuits.

[0021] To address the technical problems of heat dissipation obstruction, equipment overheating, and electrical short circuits caused by dust, snow, water accumulation, and ice buildup in energy storage boxes, this invention provides a protective device for photovoltaic energy storage power station energy storage boxes. This protective device can remove dust, snow, and ice buildup from the surface of the energy storage box, achieving reliable and safe protection for the energy storage box.

[0022] It should be noted that the protective device provided by the present invention is used for, but not limited to, the protection of energy storage boxes in photovoltaic energy storage power stations. For ease of explanation, this invention will only use the application of the protective device to the protection of energy storage boxes in photovoltaic energy storage power stations as an example. The principle of the protective device applied to other types of equipment is essentially the same as the principle of its application to the protection of energy storage boxes in photovoltaic energy storage power stations, and will not be described in detail here.

[0023] This invention provides a protective device 10 for a photovoltaic energy storage power station's energy storage box, such as... Figure 1 As shown, the protective device 10 includes a moving mechanism 100, a side protection mechanism 200, and a top protection mechanism 300. The moving mechanism 100 includes a maintenance guide rail 110 and a maintenance moving frame 120. The maintenance guide rail 110 is arranged on both sides of the energy storage box 20 in the arrangement direction, and the maintenance moving frame 120 can move along the maintenance guide rail 110. The side protection mechanism 200 is connected to the maintenance moving frame 120. The side protection mechanism 200 includes a cleaning part 210 and a first vibration part 220. The cleaning part 210 and the first vibration part 220 are used for cleaning the sides of the energy storage box 20. The top protection mechanism 300 is connected to the maintenance moving frame 120. The top protection mechanism 300 includes a cleaning part 310, a pushing part 320, and a second vibration part 330. The cleaning part 310, the pushing part 320, and the second vibration part 330 are used for cleaning the top of the energy storage box 20.

[0024] The mobile mechanism 100 serves as the walking base for the maintenance operation of the protective device 10. The maintenance guide rail 110 is symmetrically arranged on both sides along the length of the energy storage box 20. The maintenance mobile frame 120 can be slidably mounted on the maintenance guide rail 110 and moves back and forth by relying on the guide rail, thereby completing the cleaning and maintenance operation on the outside of the energy storage box 20.

[0025] In some embodiments, such as Figure 1 and Figure 2 As shown, the moving mechanism 100 also includes a moving guide rail 130 and an exchange docking assembly located on the moving guide rail 130. The extending direction of the moving guide rail 130 is perpendicular to the extending direction of the maintenance guide rail 110. The exchange docking assembly is used to transfer the maintenance moving frame 120 onto the maintenance guide rail 110.

[0026] In this embodiment, by adding a movable guide rail 130 perpendicular to the maintenance guide rail 110 and an exchange docking component, the maintenance mobile frame 120 can be transferred and docked across workstations, enabling flexible switching of operations between multiple energy storage box 20 guide rails, expanding the applicability of the device, and improving the maintenance versatility of multiple energy storage boxes 20 in the whole station.

[0027] In some embodiments, such as Figure 2 and Figure 3As shown, the exchange docking assembly includes a movable base 140 and exchange docking guide rails 150 connected to both ends of the movable base 140. The exchange docking guide rails 150 are used to dock with the maintenance guide rails 110. The movable base 140 is provided with a fixing member 160 for fixing the maintenance mobile frame 120. For example, a fixing electric cylinder is installed on the movable base 140, and a matching positioning hole is opened at the bottom of the maintenance mobile frame 120. The telescopic rod of the fixing electric cylinder can be inserted into the positioning hole to achieve reliable locking. The bottom of the maintenance mobile frame 120 is also equipped with a traveling wheel 170 and a traveling motor 180. The traveling motor 180 drives the traveling wheel 170 to achieve overall walking displacement.

[0028] In this embodiment, the movable seat 140, in conjunction with the two-end exchange docking guide rails 150, can be precisely aligned and connected with the maintenance guide rail 110. The locking structure forms a limit and fixation on the maintenance movable frame 120, which can effectively ensure that the maintenance movable frame 120 is transported smoothly and without deviation or misalignment.

[0029] The side protection mechanism 200 is used for cleaning and maintaining the outer wall of the energy storage box 20. The cleaning part 210 of the side protection mechanism 200 can be used to clean dust and snow from the outer wall of the energy storage box 20, and the first vibration part 220 of the side protection mechanism 200 can generate vibration to break and remove ice adhering to the outer wall of the energy storage box 20. For example, the side protection mechanism 200 is provided on both sides of the maintenance mobile frame 120.

[0030] In some embodiments, such as Figure 4 and Figure 6 As shown, the side protection mechanism 200 also includes a spraying section 230 and a connecting box 280. The spraying section 230 is connected to the connecting box 280, and the spraying section 230 can spray water onto the side of the energy storage box.

[0031] In this embodiment, each of the two side protection mechanisms 200 is equipped with a spraying section 230, or one of the side protection mechanisms 200 is equipped with a spraying section 230. The spraying section 230 has spray holes, and the side protection mechanism 200 is equipped with a connecting box 280. A transmission box 290 is installed on one side of the maintenance mobile frame 120, and the transmission box 290 is connected to the connecting box 280 and the adsorption component 400. By deploying the connecting box 280 and the spraying section 230, this device can directionally spray water onto the side wall of the energy storage tank, which can soften stubborn dust, stubborn stains, and hardened ice, assisting in cleaning operations and significantly improving the side wall cleaning and ice-melting effect. Simultaneously, the sprayed water flow can also dissipate heat and cool the energy storage tank, further ensuring a stable operating environment for the equipment.

[0032] In some embodiments, such as Figure 4 and Figure 6As shown, the side protection mechanism 200 also includes a first electric cylinder 240 and a first position frame 250. The first electric cylinder 240 is fixed on the maintenance moving frame 120, and the first position frame 250 fixes the cleaning part 210, the first vibration part 220 and the spraying part 230. The first electric cylinder 240 is used to adjust the distance between the first position frame 250 and the side wall of the energy storage box.

[0033] In some embodiments, such as Figure 4 and Figure 6 As shown, the first mounting bracket 260 and the second mounting bracket 270 are rotatably mounted on the first mounting bracket 250. The cleaning part 210, the first vibration part 220 and the spraying part 230 are disposed between the first mounting bracket 260 and the second mounting bracket 270. The cleaning part 210, the first vibration part 220 and the spraying part 230 can rotate sequentially to approach the side wall of the energy storage box.

[0034] In this embodiment, the side protection mechanism 200 includes a first electric cylinder 240 mounted on a maintenance mobile frame 120. A first position frame 250 is fixedly mounted on the telescopic rod of the first electric cylinder 240. A third motor 251 is mounted on the first position frame 250, and a first mounting frame 260 and a second mounting frame 270 are rotatably mounted thereon. The cleaning unit 210, the first vibration unit 220, and the spraying unit 230 are all mounted between the two sets of mounting frames. The first mounting frame 260 is driven by the third motor 251 to complete its rotational movement. The first mounting frame 260 is equipped with a first motor 211 and a second motor 221, which can independently drive the cleaning unit 210 and the first vibration unit 220 to operate. By adjusting the telescopic reach of the first position frame 250 driven by the first electric cylinder 240, the distance between each functional component and the side wall of the energy storage box can be flexibly adjusted, adapting to various specifications of energy storage boxes 20. This ensures that various cleaning operations are properly aligned and avoids collisions with the box during operation, effectively improving the device's adaptability and operational stability. At the same time, relying on the first position frame 250 to drive the two sets of mounting frames to rotate and swing, each working component can sequentially approach the side wall of the energy storage box to carry out work, realizing that water spraying, sweeping, and vibration decontamination are carried out in an orderly manner, with each structure not interfering with each other, and the overall operation process is smoother.

[0035] The top protection mechanism 300 is a mechanism for cleaning and maintaining the outer top of the energy storage box 20. The cleaning part 310 of the top protection mechanism 300 can be used to clean the dust on the outer top of the energy storage box 20. The pushing part 320 of the top protection mechanism 300 can be used to clear the snow and broken ice on the outer top of the energy storage box 20; the second vibration part 330 of the top protection mechanism 300 can break and remove the ice attached to the outer top of the energy storage box 20 by generating vibration.

[0036] In some embodiments, such as Figure 7 and Figure 8As shown, the top protection mechanism 300 also includes a second electric cylinder 340 and a second position frame 350. The second electric cylinder 340 is fixed on the maintenance moving frame 120, and the second position frame 350 fixes the cleaning part 310, the pushing part 320 and the second vibration part 330. The second electric cylinder 340 is used to adjust the distance between the second position frame 350 and the top of the energy storage box.

[0037] In some embodiments, such as Figure 7 and Figure 8 As shown, the second position frame 350 is rotatably mounted with a first mounting gear 360 and a second mounting gear 370. A pushing part 320, a cleaning part 310 and a second vibration part 330 are disposed between the first mounting gear 360 and the second mounting gear 370. The pushing part 320, the cleaning part 310 and the second vibration part 330 can rotate sequentially toward the top of the energy storage box.

[0038] In this embodiment, the top protection mechanism 300 includes a second electric cylinder 340 disposed on the top of the maintenance movable frame 120. A second position frame 350 is disposed on the telescopic rod of the second electric cylinder 340. A first mounting gear 360 and a second mounting gear 370 are rotatably mounted at both ends of the second position frame 350, and a shifting motor 391 is also disposed at both ends of the second position frame 350. A shifting gear 390 is disposed on the output shaft of the shifting motor 391. The shifting gear 390 meshes with the first mounting gear 360 and the second mounting gear 370. A drive motor 381 is mounted on the gear plate 360, and a drive shaft 380 is mounted on the output shaft of the drive motor 381. A drive disk 371 is rotatably mounted on the second gear plate 370, and the drive disk 371 is connected to the end of the drive shaft 380. An electromagnetic clamping gear 372 is rotatably mounted on the second gear plate 370. An electromagnetic clamping plate is provided on the inner side of the electromagnetic clamping gear 372, and the electromagnetic clamping gear 372 meshes with the drive disk 371. The electromagnetic clamping plate is used to clamp and drive the pushing part 320, the cleaning part 310, and the second vibration part 330. The pushing unit 320 includes a pushing member rotatably mounted between the first mounting gear 360 and the second mounting gear 370. One end of the pushing member is located inside the electromagnetic clamping gear 372, and the end of the pushing member is clamped and fixed by an electromagnetic clamping plate to drive the drive disk 371 to rotate. The cleaning unit 310 includes a cleaning member rotatably mounted between the first mounting gear 360 and the second mounting gear 370. One end of the cleaning member is located inside the electromagnetic clamping gear 372, and the end of the cleaning member is clamped and fixed by an electromagnetic clamping plate to drive the cleaning member to rotate.

[0039] In this embodiment, the top protection mechanism 300 is equipped with a second electric cylinder 340 and a second positioning frame 350, which can precisely adjust the distance between the pushing part 320, the cleaning part 310, and the second vibration part 330 and the top of the energy storage box. It can adapt to energy storage boxes of different heights, ensuring that the cleaning of snow, ice, and various debris on the top is properly aligned. The adjustment operation is simple and has better universal adaptability. In addition, various functional components are arranged by rotating the first mounting gear plate 360 ​​and the second mounting gear plate 370, which can drive the pushing part 320, the cleaning part 310, and the second vibration part 330 to rotate and align with the top surface of the energy storage box in sequence, completing the snow pushing, sweeping, and vibration de-icing processes in a timed manner. The overall structure is compact, and the various operations are carried out in an orderly manner without mutual interference.

[0040] In some embodiments, such as Figure 4 and Figure 5 As shown, the top protection mechanism 300 also includes an adsorption assembly 400, which includes a third electric cylinder 410, an adsorption transmission cylinder 420, and a telescopic frame 430 that connects the third electric cylinder 410 and the adsorption transmission cylinder 420 respectively. The adsorption transmission cylinder 420 is used to adsorb the liquid on the top of the energy storage tank.

[0041] In this embodiment, the adsorption assembly 400 is installed on top of the maintenance mobile frame 120 and mainly consists of a third electric cylinder 410, a telescopic frame 430, and an adsorption transfer cylinder 420. A first spring 440 connects the telescopic rod of the third electric cylinder 410 and the telescopic frame 430 to achieve elastic telescopic buffering. The adsorption transfer cylinder 420 and a fourth motor 450 are fixedly mounted on the telescopic frame 430. The fourth motor 450 drives the adsorption transfer cylinder 420 to operate, and one end of the adsorption transfer cylinder 420 is connected to the transfer box 290. The adsorption assembly 400 can flexibly extend and retract with the third electric cylinder 410 to approach the top of the energy storage box, and can promptly absorb residual water and snowmelt water on the surface of the box, effectively avoiding safety problems such as box corrosion and electrical short circuits caused by long-term water retention, and further improving the overall protection effect and operational safety of the energy storage box.

[0042] In some embodiments, such as Figure 9 and Figure 10 As shown, both the first vibration unit 220 and the second vibration unit 330 include a vibration cylinder 331, a push shaft 332, an eccentric contact wheel 333, a telescopic contact seat 334 and a striking part 336 located inside the vibration cylinder 331. The striking part 336 is used to contact the surface of the energy storage box.

[0043] In this embodiment, the first vibration unit 220 and the second vibration unit 330 can have completely identical structures, differing only in their mounting and fixing positions. The vibration unit includes a vibration cylinder 331. On the side protection mechanism 200, the vibration cylinder 331 is disposed between the first mounting bracket 260 and the second mounting bracket 270; on the top protection mechanism 300, the vibration cylinder 331 is disposed between the first mounting toothed disc 360 and the second mounting toothed disc 370. A drive shaft 332 is rotatably mounted inside the vibrating cylinder 331. An eccentric contact wheel 333 is provided on the drive shaft 332, and a telescopic contact seat 334 is telescopically provided on the vibrating cylinder 331. A second spring 335 is connected between the telescopic contact seat 334 and the vibrating cylinder 331. A striking part 336 is telescopically provided on the telescopic contact seat 334, and a third spring 337 is connected between the striking part 336 and the telescopic contact seat 334. The circumferential area of ​​the eccentric contact wheel 333 is in tangential contact with the telescopic contact seat 334. On the side protection mechanism 200, the drive shaft 332 is driven by a second motor 221. On the top protection mechanism 300, the end of the drive shaft 332 is located inside the electromagnetic clamping gear 372, and the end of the drive shaft 332 is clamped and fixed by an electromagnetic clamping plate to drive the drive shaft 332 to rotate. By employing a structure consisting of a drive shaft 332, an eccentric contact wheel 333, a telescopic contact seat 334, and a striking part 336, the vibrating part can generate regular vibrations and gently strike the surface of the energy storage box. This can loosen and remove snow, ice, and stubborn dust, resulting in good decontamination and de-icing effects. Furthermore, the flexible contact is less likely to damage the outer shell of the box.

[0044] In this embodiment, the moving mechanism 100 drives the side protection mechanism 200 and the top protection mechanism 300 to reciprocate along the maintenance guide rail 110, enabling full-coverage cleaning of the top and sides of the energy storage box. The combined structure of sweeping and vibration effectively removes dust, snow, water, and ice from the surface of the energy storage box, ensuring thorough cleaning without blind spots and high operational efficiency. Simultaneously, it ensures smooth ventilation and heat dissipation of the energy storage box, preventing overheating and effectively avoiding safety hazards such as electrical short circuits and box corrosion and aging, significantly improving the operational safety and maintenance convenience of the photovoltaic energy storage power station's energy storage box.

[0045] To better understand this invention, the following is combined with... Figures 1 to 10 The technical solution of the present invention will be described in detail below: In some embodiments, the protective device 10 includes a moving mechanism 100, a side protection mechanism 200, and a top protection mechanism 300.

[0046] The mobile mechanism 100 includes a maintenance guide rail 110, a maintenance mobile frame 120, a mobile guide rail 130, a mobile base 140, and an exchange docking guide rail 150 connected to both ends of the mobile base 140. The maintenance guide rail 110 is arranged on both sides of the energy storage box 20 in the arrangement direction. The maintenance mobile frame 120 can move along the maintenance guide rail 110. The extension direction of the mobile guide rail 130 is perpendicular to the extension direction of the maintenance guide rail 110. The exchange docking guide rail 150 is used to dock with the maintenance guide rail 110. The mobile base 140 is provided with a fixing member 160 for fixing the maintenance mobile frame 120.

[0047] The side protection mechanism 200 includes a cleaning section 210, a first vibration section 220, and a spraying section 230. The cleaning section 210 and the first vibration section 220 are used for cleaning the sides of the energy storage box 20, and the spraying section 230 can spray water onto the sides of the energy storage box.

[0048] The top protection mechanism 300 includes a cleaning section 310, a pushing section 320, a second vibration section 330, and an adsorption assembly 400. The cleaning section 310, the pushing section 320, and the second vibration section 330 are used for cleaning the top of the energy storage box 20. The adsorption assembly 400 includes a third electric cylinder 410, an adsorption transmission cylinder 420, and a telescopic frame 430 that connects the third electric cylinder 410 and the adsorption transmission cylinder 420 respectively. The adsorption transmission cylinder 420 is used to adsorb liquid on the top of the energy storage box.

[0049] To better understand the workflow, its operating principles and beneficial effects are explained below.

[0050] The energy storage boxes 20 are arranged in a linear array in the installation site. During operation, the mobile base 140 can be moved laterally along the mobile guide rail 130. After arriving at the designated work area, the maintenance mobile frame 120 is smoothly transferred from the exchange docking guide rail 150 to the maintenance guide rail 110, so that the whole equipment is parked on the outside of the energy storage box 20, and all-round maintenance and cleaning operations can be carried out.

[0051] To address the dust accumulation on the side walls of the energy storage box, the first motor 211 is activated to drive the cleaning unit 210, while the first electric cylinder 240 drives the first positioning frame 250 forward, ensuring the cleaning unit 210 fits against the side walls of the box and smoothly completes the dust cleaning operation. For water accumulation on the top of the energy storage box, it can be cleaned in advance to prevent condensation in low temperatures. During operation, the third electric cylinder 410 drives the adsorption transfer cylinder 420 close to the top surface of the box. Utilizing the elastic telescopic structure of the telescopic frame 430 to adapt to the uneven structure of the top surface, the adsorption transfer cylinder 420 fits tightly against the top surface, drawing the water through the adsorption holes into the transfer box 290. The collected water can be transported to the connecting box 280, and then sprayed onto the side walls of the energy storage box by the spraying unit 230. This not only assists in cleaning stubborn stains but also helps to cool the equipment. Simultaneously, the transfer box 290 can also collect rainwater, achieving water resource recycling. In addition, by adjusting the deflection angle of the first mounting bracket 260 through the third motor 251, the operating mode can be flexibly switched to complete multiple operations such as vibration ice breaking, dust cleaning, and water spraying for cooling in sequence.

[0052] To address dust accumulation on the top of the energy storage box, the height of the second position bracket 350 is adjusted using the second electric cylinder 340. Then, the shifting motor 391 drives the first mounting gear 360 and the second mounting gear 370 to rotate, causing the cleaning section 310 to fit against the top surface of the box. Simultaneously, the drive motor 381 drives the drive disc 371, using the electromagnetic structure inside the electromagnetic clamping gear 372 to clamp the end of the cleaning section 310, providing power for the cleaning operation. When snow accumulates on the top of the box during rain or snow, the same adjustment method can be used to switch to the pushing section 320 to push away the snow.

[0053] For ice adhering to the top and side walls of the energy storage box, a vibration structure can be used to break up the ice: the drive shaft 332 drives the eccentric contact wheel 333 to rotate, and the eccentric structure continuously pushes the telescopic contact seat 334 to reciprocate, driving the striking part 336 to strike the surface of the box at high frequency. At the same time, it adapts to the undulating structure of the box surface by its own telescopic characteristics, effectively breaking up the adhering ice. The vibration structure at the side wall is directly driven by the second motor 221, while the vibration structure at the top is driven by an electromagnetic clamping gear. The broken ice can be cleaned and collected by the top cleaning part 310 and the pushing part 320, completing the protective cleaning work of the energy storage box.

Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
