Description
Technical Field
[0001] This utility model belongs to the field of energy storage equipment technology, specifically relating to a photovoltaic energy storage device that is easy to dissipate heat. Background Technology
[0002] Photovoltaic energy storage equipment refers to a device that converts solar energy into electrical energy through solar panels and stores the electrical energy using an energy storage system (such as a battery). It combines photovoltaic power generation technology and energy storage technology, enabling it to generate and store electrical energy when solar energy is abundant and release electrical energy when solar energy is insufficient, thereby achieving efficient energy utilization.
[0003] In order to improve the heat dissipation capacity of energy storage devices, existing technologies typically install multiple heat dissipation fins inside the energy storage device and open ventilation holes on the outer shell to allow air to circulate through the heat dissipation fins and carry away the heat generated by the energy storage unit. Although the above devices can achieve good ventilation and heat dissipation effects, over time, external dust will adhere to the heat dissipation fins through the ventilation holes, causing the surface of the heat dissipation fins to be covered and blocked, affecting heat exchange. Furthermore, the heat dissipation fins are usually located inside the shell, making them difficult to clean, which in turn leads to a deterioration in the heat dissipation effect of the energy storage device itself and affects the energy storage effect.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0027] like Figure 1-5 As shown, a photovoltaic energy storage device with easy heat dissipation includes a housing 1. The energy storage unit 9 and the fixing frame 10 are fixedly arranged from top to bottom inside the housing 1. The fixing frame 10 is sleeved with the bottom end of the heat dissipation fin 8 and the fixing frame 10 is connected to the heat dissipation fin 8 by bolts. A cleaning mechanism 6 is sleeved inside the heat dissipation fin 8 and the cleaning mechanism 6 is also connected to the housing 1.
[0028] The front side of the housing 1 is fixedly connected to the rear end of the air inlet pipe 5, and the air inlet pipe 5 corresponds to the middle of the heat dissipation fins 8. A solenoid valve 4 is provided on the front side of the air inlet pipe 5. The solenoid valve 4 is electrically connected to the control panel 2. The control panel 2 is fixedly provided on the front side of the housing 1. The front end of the air inlet pipe 5 is threadedly connected to the rear end of the external threaded pipe 3. A dust filter is fixedly provided inside the front end of the external threaded pipe 3. By providing a dust filter at the front end of the air inlet pipe 5, when the induced draft fan 68 draws outside air into the housing 1 through the air inlet pipe 5, the dust mixed in the incoming air can be filtered by the filter, thereby reducing the amount of dust entering the housing 1 and extending the maintenance cycle of the heat dissipation fins 8. Furthermore, by placing the filter inside the external threaded pipe 3, it is convenient to clean and replace the dust filter.
[0029] The cleaning mechanism 6 includes a diversion pipe 61. The bottom of the diversion pipe 61 is fixedly connected to the upper end of multiple suction pipes 62, and the diversion pipe 61 is connected to the suction pipes 62. The multiple suction pipes 62 are all sleeved inside the heat dissipation fins 8.
[0030] Each suction pipe 62 has suction grooves 63 on both the left and right sides, and the upper middle part of the diversion pipe 61 is fixedly connected to the bottom end of the translation block 65.
[0031] The upper end of the translation block 65 is fitted into the mounting groove 7, which is located on the upper inner side of the housing 1. The upper end of the translation block 65 has a screw hole that is threadedly connected to the screw rod 612. When it is necessary to clean the dust attached to the heat dissipation fins 8 during use, the user can close the solenoid valve 4 and the solenoid valve 613 through the control panel 2, and open the motor 64 and the solenoid valve 69. At this time, the fan 68 sucks out the dust on the heat dissipation fins 8 through the three-way pipe 611, the telescopic hose 66, the diversion pipe 61, and the suction pipe 62. When the motor 64 is working, it drives the translation block 65, the diversion pipe 61, and the suction pipe 62 to move through the screw rod 612 and the screw hole, so that the suction pipe 62 moves in close contact with the heat dissipation fins 8 to clean the dust on the heat dissipation fins 8 and collect and store the dust in the dust collection bag 67. This allows for regular cleaning of the heat dissipation fins 8 to ensure good heat dissipation and effectively improves the convenience of maintenance of this device.
[0032] Limit switches are provided on both the front and rear sides of the translation block 65, and the two limit switches are fixedly connected to the front and rear inner sides of the housing 1 respectively. The rear optical shaft of the screw 612 is rotatably connected to the rear inner side of the mounting groove 7 through a bearing. By providing limit switches on both the front and rear sides of the translation block 65, the displacement of the translation block 65 can be limited when the motor 64 drives the translation block 65 to move back and forth, so as to assist the user in judging and controlling the position of the translation block 65 and the diverter pipe 61.
[0033] The front end of the screw 612 is fixedly connected to the output shaft of the motor 64, the front end of the motor 64 is fixedly connected to the front end of the mounting slot 7, and the motor 64 is also electrically connected to two limit switches and the control panel 2.
[0034] The rear side of the diverter pipe 61 is fixedly connected to the front end of the telescopic hose 66, and the rear end of the telescopic hose 66 passes through the housing 1 and the right side of the sealing box 610 and is fixedly connected to the right end of the tee pipe 611.
[0035] The front end of the sealed box 610 is fixedly connected to the rear side of the housing 1. A solenoid valve 69 is provided on the rear side of the telescopic hose 66. The left end of the three-way pipe 611 is fixedly connected to the rear end of the air duct 614.
[0036] The front end of the air duct 614 is fixedly connected to the rear side of the housing 1 and the air duct 614 is connected to the inside of the housing 1. A solenoid valve 613 is provided on the rear side of the air duct 614. The rear end of the three-way pipe 611 is fixedly connected to the suction pipe of the air blower 68. When the photovoltaic power generation is stored using the energy storage unit 9, the user can control the air blower 68 to work through the control panel 2 and open the solenoid valve 4 and the solenoid valve 613, so that the outside air enters the inside of the housing 1 through the air inlet pipe 5 and contacts the heat dissipation fins 8. The air inside the housing 1 is then sucked out through the air duct 614, which accelerates the air flow rate at the heat dissipation fins 8 and improves the heat dissipation effect of the heat dissipation fins 8.
[0037] The induced draft fan 68 is fixedly connected to the inside of the mounting box via a mounting base. The exhaust pipe of the induced draft fan 68 extends to the outside of the sealed box 610 and is connected to the opening of the dust collection bag 67.
[0038] The working principle of this utility model is as follows: When the photovoltaic power generation is stored using the energy storage unit 9, the user can control the fan 68 to work through the control panel 2 and open the solenoid valve 4 and the solenoid valve 613, so that the outside air enters the inside of the housing 1 through the air inlet pipe 5 and comes into contact with the heat dissipation fins 8, and the air inside the housing 1 is sucked out through the air inlet pipe 614, thereby accelerating the air flow rate at the heat dissipation fins 8.
[0039] When it is necessary to clean the dust attached to the heat dissipation fins 8 during use, the user can close solenoid valve 4 and solenoid valve 613 through the control panel 2, and open motor 64 and solenoid valve 69. At this time, the exhaust fan 68 sucks out the dust on the heat dissipation fins 8 through the three-way pipe 611, telescopic hose 66, diverter pipe 61 and suction pipe 62. When the motor 64 is working, it drives the translation block 65, diverter pipe 61 and suction pipe 62 to move through the screw 612 and screw hole, so that the suction pipe 62 moves in close contact with the heat dissipation fins 8 to clean the dust on the heat dissipation fins 8 and collect and store the dust in the dust collection bag 67. When the translation block 65 moves to the end of the screw 612, it contacts the limit switch and stops the motor 64 from working.
[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
