DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0024] As Figures 1-6 The utility model provides a kind of temperature monitoring device for photovoltaic inverter, including inverter shell 1, the side fixed mounting of inverter shell 1 has fixed frame 2, temperature monitor 3 is installed in the inside of fixed frame 2, temperature detector 3 rear side is installed with connecting pipe 4 penetrating inverter shell 1, sensing circuit 5 is installed in the inside of connecting pipe 4, temperature probe 6 is installed in the output end of sensing circuit 5, alarm 7 is installed in the rear end of temperature detector 3 and located the side of connecting pipe 4.

[0025] Temperature detector 3 side is installed with circuit pipe 8 penetrating fixed frame 2, temperature regulator 9 is installed in the output end of circuit pipe 8, temperature regulating pipe 10 is installed in the rear end of temperature regulator 9 and penetrates inverter shell 1.

[0026] The inside of the fixed frame 2 is provided with a protective pad 11, and the top of the fixed frame 2 is provided with a top plate 12 which is hingedly installed. When the temperature detector 3 is placed in the fixed frame 2, the top plate 12 installed on the top of the fixed frame 2 needs to be opened, the temperature detector 3 is aligned with the inside of the fixed frame 2, and then inserted into the space in the fixed frame 2. The top plate 12 can form a semi-closed space with the fixed frame 2 to firmly fix the temperature detector inside, prevent the temperature detector 3 from moving due to external force, and cause the components connected to the rear side of the temperature detector 3 to fall off, so that the temperature detector 3 cannot monitor the temperature inside the photovoltaic inverter in real time. When the temperature is too high, the photovoltaic inverter inside cannot be quickly cooled in time, causing the internal components to be damaged. The protective pad 11 in the fixed frame 2 is used to protect the temperature detector 3. When the temperature detector 3 is placed in the fixed frame 2, the protective pad 11 can prevent the temperature detector 3 from directly contacting the fixed frame 2, so that the surface of the temperature detector 3 is not worn and damaged. At the same time, the protective pad 11 can increase the friction with the temperature detector 3, prevent the temperature detector 3 from shaking randomly in the fixed frame 2, and improve the safety of the whole device.

[0027] The two sides of the fixed frame 2 are respectively provided with mounting blocks 13, and the surface of each mounting block 13 is provided with a plurality of screw holes 14. When the fixed frame 2 needs to be installed on the side of the inverter shell 1, the mounting block 13 on the side of the fixed frame 2 can be installed by the screw holes 14, so that the fixed frame 2 is closely attached to the side of the inverter shell 1, and then the fixed screws are screwed into the screw holes 14 to fix the mounting block, so that the whole fixed frame 2 is fixed on the side of the inverter shell 1.

[0028] The two sides of the inverter shell 1 are respectively provided with a group of windows, and each group of windows is respectively provided with a ventilation plate 15 and a filter plate 16. When the temperature inside the photovoltaic inverter is too high, the temperature controller 9 can transport cold air into the photovoltaic inverter through the temperature control pipe 10 to achieve the effect of controlling the temperature. The ventilation plate 15 installed on the two sides of the inverter shell 1 can discharge the original hot air in the inverter to the outside of the device while the temperature controller 9 transports cold air into the inverter, forming a circulation to achieve a better temperature control effect. The filter plate 16 in the ventilation plate 15 can filter the dust in the air to prevent the dust in the air from entering the inverter and damaging the electronic components in the inverter.

[0029] Specifically, the side of the fixed frame 2 is provided with a plurality of output ports, and each output port is provided with a rubber plug 17. The rubber plug 17 installed on the side of the fixed frame 2 can seal the output port when the output port is not in use, preventing the output port from being blocked due to changes in external weather and causing the output port to be unable to be normally used.

[0030] More specifically, the bottom of the fixed frame 2 is provided with a battery box 18, a plurality of groups of batteries 19 are installed in the battery box 18, and the output ends of the plurality of groups of batteries 19 are connected to the temperature detector 3 through the bottom of the fixed frame 2. The batteries 19 installed in the battery box 18 can supply power to the temperature detector 3 installed in the fixed frame 2, so that the temperature detector 3 can be normally used to monitor the inside of the photovoltaic inverter, and can supply power to the temperature regulator 9. When the temperature inside the photovoltaic inverter is too high, the temperature regulator 9 can quickly regulate the temperature inside the photovoltaic inverter, protect the safety of the electronic components inside the photovoltaic inverter, and increase the service life of the photovoltaic inverter.

[0031] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
