DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 to Figure 5 A photovoltaic energy storage control device shown includes a box body 1, a control instrument 15 is fixedly installed inside the box body 1, and the control instrument 15 is arranged between the photovoltaic power generation structure and the energy storage system (not shown in the figure). The control instrument 15 is used to realize intelligent regulation of photovoltaic power generation and energy storage system, such as: the intelligent operation of the system can be regulated according to the electricity price, time period, user electricity consumption characteristics and rules, photovoltaic power generation time period output and power changes issued by the local power grid. The control instrument 15 can be remotely monitored and controlled to maximize the benefits and reduce labor costs. Since the photovoltaic and energy storage systems are in a continuous working state, and the control instrument 15 needs to continuously perform intelligent regulation on the photovoltaic power generation and energy storage systems, in addition, the control instrument 15 needs external power supply to operate, so the control instrument 15 will generate more heat during use. The control instrument 15 and its control principle are existing common technologies and will not be elaborated here.

[0025] Considering that the control instrument 15 will generate a lot of heat during long-term use, in order to prevent the heat from accumulating inside the box body 1 and affecting the service life of the control instrument 15, a square opening 2 is opened at the bottom of the side wall of the box body 1, and a square box 3 is fixedly connected inside the square opening 2, and the external air enters the box body 1 through the square box 3. A filter plate 4 is fixedly connected inside the square box 3. When the external air enters the box body 1 through the square box 3, the filter plate 4 can filter dust and impurities.

[0026] Considering that dust and impurities are easily attached and accumulated on the filter plate 4 and affect the air intake efficiency, in order to clean the dust and impurities attached and accumulated on the filter plate 4, a cavity 5 is opened inside the wall of the square box 3, and a suction port 6 is opened on the inner wall of the square box 3. The suction port 6 is provided in multiple numbers, and the multiple suction ports 6 are evenly distributed on the inner wall of the square box 3. The suction port 6 is connected to the cavity 5. The suction port 6 is located on the side of the filter plate 4 close to the outside of the box body 1, and the box body 1 is provided with a wind component that cooperates with the cavity 5.

[0027] The wind power assembly includes a suction pipe 8, a pump body 10, a first air inlet end 11, a second air inlet end 12, a first air outlet end 13 and a second air outlet end 14. The pump body 10 is fixedly connected to the outer wall of the box body 1. The pump body 10 is located on the side of the box body 1 away from the square box 3 to ensure the circulation of air inside the box body 1. The pump body 10 is a four-way air pump. The first air inlet end 11, the second air inlet end 12, the first air outlet end 13 and the second air outlet end 14 are all connected to the pump body 10. The second air inlet end 12 and the first air outlet end 13 extend to the inside of the box body 1. The suction pipe 8 is connected between the cavity 5 and the first air inlet end 11.

[0028] Solenoid valves are fixedly mounted on the first air inlet end 11 , the second air inlet end 12 , the first air outlet end 13 and the second air outlet end 14 .

[0029] A filter box 16 is provided on the suction pipe 8 , and a filter device is provided inside the filter box 16 , and the filter device includes a filter screen and other structures, and can filter dust and impurities. The filter box 16 is fixedly connected to the outer wall of the box body 1 .

[0030] During ventilation and heat dissipation, the solenoid valve on the second air inlet end 12 is opened, and the solenoid valve on the second air outlet end 14 is opened. During the operation of the pump body 10, the external air is sucked into the box body 1 through the square box 3 and discharged from the second air outlet end 14, so as to realize ventilation and heat dissipation inside the box body 1;

[0031] At the same time, the filter plate 4 can filter dust and impurities in the air.

[0032] When there is a lot of dust attached to and accumulated on the filter plate 4, the solenoid valve on the second air inlet end 12 is closed, the solenoid valve on the second air outlet end 14 is closed, the solenoid valve on the first air outlet end 13 is opened, and the solenoid valve on the first air inlet end 11 is opened. The pump body 10 supplies air to the inside of the box body 1 through the first air outlet end 13, and the wind is blown to the outside by the square box 3, so that the dust and impurities attached to and accumulated on the filter plate 4 fall off. In this process, the pump body 10 sucks the fallen dust and impurities through the suction pipe 8, the cavity 5 and the suction port 6, and filters the dust and impurities accumulated inside the filter box 16, thereby completing the automatic cleaning of dust and impurities.

[0033] At the same time, in order to ensure the timeliness of automatic cleaning, a wind sensor 7 is fixedly connected to the inner wall of the square box 3, and the wind sensor 7 is located on the side of the filter plate 4 close to the inside of the box 1. When there is a lot of dust attached to the filter plate 4, the wind force of the gas inside the square box 3 will be reduced, and the wind sensor 7 can monitor the wind force. When the wind force is small, the dust and impurities are automatically cleaned. At the same time, since the time of automatic cleaning is short and the box 1 also forms airflow, it will not affect the heat dissipation of the box 1.

[0034] A controller 9 is fixedly installed on the inner wall of the box body 1. Specifically, the controller 9 is used to connect between multiple solenoid valves and the wind sensor 7. When the wind sensor 7 detects that the wind force is lower than the set threshold, this information is transmitted to the controller 9. The controller 9 controls the switching between the multiple solenoid valves. The controller 9 and its control principle are existing common technologies and will not be elaborated here.
