The system absorbs solar energy through photovoltaic panels and converts it into electrical energy, and uses energy storage modules (such as batteries) to store electrical energy for use at night or in rainy weather. At the same time, it is equipped with a diesel generator as a backup power source to ensure energy supply when photovoltaic power generation is insufficient or system maintenance occurs. It has a high self-sufficiency rate and reduces dependence on external power supply.

However, maintenance is often forgotten during actual use, resulting in weakened filtering effect and poor exhaust of the diesel generator, which needs to be improved. Summary of the invention

[0005] The present application provides a self-cleaning solar-storage-diesel power supply device that can automatically clean the filter without the need for manual cleaning or replacement of the filter, thereby improving the user experience and avoiding the problems of weakened filtering effect and poor exhaust of the diesel generator.

[0006] The present application provides a self-cleaning solar-storage-diesel power supply device, which adopts the following technical solution: A self-cleaning photovoltaic-diesel power supply device comprises a box-type room, a battery, a photovoltaic panel and a diesel generator, wherein the box-type room is fixed with a box body, the exhaust end of the diesel generator is connected to the inner bottom of the box body, an exhaust pipe is arranged on the top of the box body, a rotating groove is arranged in the box body, an outer frame is rotatably arranged in the rotating groove, multiple layers of filter screens are fixed at intervals in the outer frame, a reduction motor for driving the outer frame to rotate is fixed to the box body, a driving mechanism and an inner frame driven to slide by the driving mechanism are arranged on the outer frame, a plurality of brushes are fixed on the inner frame, the multiple brushes are respectively in contact with the bottom surfaces of multiple filter screens, and a collecting cylinder is arranged at one end of the outer frame.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 This embodiment discloses a self-cleaning photovoltaic-storage-diesel power supply device, including a box-type house 1, a battery 11, a photovoltaic panel 12 and a diesel generator 13. The box-type house 1 is also provided with power conversion equipment such as an energy storage converter and an on-grid and off-grid switching cabinet. The photovoltaic panel 12 is located outside the box-type house 1. The photovoltaic panel 12 can be installed on the top of the box-type house 1 or on the ground nearby. The electricity generated by the photovoltaic panel 12 is stored in the battery 11 through a wire, and the diesel generator 13 serves as a backup power source.

[0031] Reference Figure 1 and Figure 2 The box-type room 1 is fixed with a box body 2, the exhaust end of the diesel generator 13 is connected to the inner bottom of the box body 2, and an exhaust pipe 21 is provided on the top of the box body 2.

[0032] Reference Figure 2 and Figure 3A rotating groove 22 is provided in the box body 2, and an outer frame 3 is rotatably provided in the rotating groove 22. Multiple layers of filter screens 31 are fixed at intervals in the outer frame 3. The mesh size of the filter screen 31 gradually decreases in the direction close to the exhaust pipe 21. The smoke particles of different sizes are filtered by the multiple layers of filter screens 31, which is not easy to cause blockage and has a longer service life. A reduction motor 23 is fixed to the box body 2 to drive the outer frame 3 to rotate, and the reduction motor 23 can rotate forward and reverse. A driving mechanism and an inner frame 32 driven to slide by the driving mechanism are provided on the outer frame 3. Multiple brushes 33 are fixed on the inner frame 32, and the multiple brushes 33 are in contact with the bottom surfaces of multiple filter screens 31 respectively. A collecting barrel 4 is provided at one end of the outer frame 3. After the reduction motor 23 rotates the outer frame 3 to a vertical state, the collecting barrel 4 is just located at the vertical bottom of the outer frame 3.

[0033] The driving mechanism includes a driving motor 34 and a screw 35 driven to rotate by the driving motor 34. The driving motor 34 can rotate forward and reversely. The driving motor 34 is fixed to the outer frame 3. The screw 35 is rotatably connected to the outer frame 3. The screw 35 is threadedly connected to the inner frame 32. The outer frame 3 is fixed with a guide rod 36. The number of the guide rods 36 is several. The guide rods 36 are arranged parallel to the screw 35. The guide rods 36 penetrate the inner frame 32 and are slidably connected to the inner frame 32. The driving motor 34 drives the screw 35 to rotate, and the screw 35 drives the inner frame 32 to slide through the threaded connection, thereby driving the brush 33 to clean the bottom surface of the filter screen 31. The guide rod 36 provides a guiding effect for the sliding of the inner frame 32, thereby improving the stability of the sliding of the inner frame 32.

[0034] The outer frame 3 is fixed with an L-shaped rod 37, and the top of the collecting barrel 4 is provided with a rotating hole 41 for the L-shaped rod 37 to be inserted. The collecting barrel 4 is rotatably connected to the outer frame 3 through the rotating hole 41 at the top, and a collecting groove 42 is provided on the top surface of the collecting barrel 4. The center of gravity of the collecting barrel 4 is located below the rotating hole 41. The collecting barrel 4 keeps the collecting groove 42 facing upward under the action of gravity, that is, no matter whether the outer frame 3 is in a horizontal state or a vertical state, the collecting groove 42 of the collecting barrel 4 faces upward, and the garbage in the collecting barrel 4 will not fall out.

[0035] The groove wall of the rotating groove 22 is provided with two horizontal abutment surfaces 221, the two abutment surfaces 221 are respectively located in the diagonal direction of the outer frame 3, and the two abutment surfaces 221 are respectively in contact with one side of the top surface and one side of the bottom surface of the outer frame 3. The abutment surfaces 221 of this embodiment are formed on a plate protruding and fixed on the inner wall of the rotating groove 22, and the limit rotation position of the outer frame 3 is defined by the abutment surfaces 221. When the two abutment surfaces 221 are in contact with the outer frame 3, the outer frame 3 is just in a horizontal state, and the abutment surfaces 221 prevent the smoke from being discharged upward through the outside of the outer frame 3 by closing the two ends of the outer frame 3, so that the smoke must pass through the filter screen 31 when passing through the box body 2.

[0036] Reference Figure 4The side wall of the box body 2 is provided with a cleaning slot 24 for the collection barrel 4 to enter and exit. When the outer frame 3 is in a horizontal state, the end of the collection barrel 4 faces the cleaning slot 24. A plug cover 25 is provided in the cleaning slot 24 to prevent the smoke in the box body 2 from leaking out. After removing the plug cover 25, the collection barrel 4 can be pulled outwards. The collection barrel 4 can be separated from the L-shaped rod 37 by horizontal movement. After the collection barrel 4 is pulled out of the box body 2, the garbage in the collection barrel 4 can be cleaned.

[0037] Reference Figure 1 The outer wall of the box-type room 1 is provided with an exhaust groove 14, and the end of the exhaust pipe 21 away from the box body 2 is located in the exhaust groove 14 and faces the opening of the exhaust groove 14. The exhaust groove 14 and the end of the exhaust pipe 21 that are horizontally opened outward will not block the exhaust, and rainwater is not easy to enter the outer end of the exhaust pipe 21.

[0038] Reference Figure 5 The end of the exhaust pipe 21 located in the exhaust groove 14 is detachably connected with an exhaust hose 5, and the detachable connection method can be a joint connection, a threaded connection or a sleeve connection. After the exhaust hose 5 is connected to the exhaust pipe 21, the exhaust hose 5 serves as the exhaust outlet of the exhaust gas. The personnel can hold the free end of the exhaust hose 5 and blow air to clean the surface of the photovoltaic panel 12. This blowing cleaning method utilizes the exhaust kinetic energy of the diesel generator 13, does not require the participation of another fan, and does not consume energy. The exhausted gas is hot air, which has a good drying and blowing effect on dust that is wet, so it is easy to clean the surface of the photovoltaic panel 12, thereby ensuring the power generation efficiency of the photovoltaic panel 12. When the exhaust hose 5 is not in use, it can be removed and stored, or the exhaust hose 5 can be directly plugged into the exhaust groove 14 for easy use next time.

[0039] The implementation principle of a self-cleaning solar-diesel power supply device in an embodiment of the present application is: when the diesel generator 13 is running, the exhaust gas enters from the bottom of the box 2, the exhaust gas is filtered through the multi-layer filter screen 31 in the box 2, and the filtered exhaust gas is discharged from the exhaust pipe 21 at the top of the box 2.

[0040] After the diesel generator 13 stops running, the reduction motor 23 is controlled by the switch on the control system to rotate the outer frame 3 to a vertical state, the collecting barrel 4 is located at the bottom of the outer frame 3 and the opening is facing upward, and then the driving motor 34 is operated to drive the inner frame 32 and all the brushes 33 to move through the screw 35, and the brushes 33 brush and clean the mesh surface of the filter 31, and the dust particles brushed down fall into the collecting barrel 4. The brush 33 moves back and forth several times to complete the cleaning, and then the brush 33 is reset and the outer frame 3 is reset to a horizontal state.

[0041] Through the above scheme, the dusty side of the filter 31 can be brushed, and the cleaned dust will not contaminate the filter 31 at the lower layer, and the cleaning effect is better; the dust and garbage swept down can be automatically collected, and the collection cylinder 4 is convenient for taking out and dumping the garbage. Through the above structure, combined with the control system, automatic operation can be achieved, and the self-cleaning of the photovoltaic and diesel power supply device can be achieved, avoiding the problem of weakened filtering effect and poor exhaust of the diesel generator 13.

[0042] In addition, by the orientation of the exhaust pipe 21 and the arrangement of the exhaust hose 5, the exhaust gas discharged from the diesel generator 13 can be utilized to blow and clean the photovoltaic panel 12, and the exhaust hose 5 is easy to connect and store.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
