Description

Technical Field

[0001] This utility model relates to the field of photovoltaic water pumping frequency converter technology, and in particular to a dedicated photovoltaic water pumping frequency converter. Background Technology

[0002] Photovoltaic water pumping is a technology that uses solar photovoltaic power generation to drive water pumps to pump water. It is mainly used in agricultural and forestry irrigation, desertification control, grassland animal husbandry, municipal water supply and village water supply. The core equipment of the solar photovoltaic water pumping system is the frequency converter, which can process and control the electrical energy output by the photovoltaic array.

[0003] Currently, most existing photovoltaic water pumping frequency converters are installed outdoors, which makes them susceptible to environmental factors. When the frequency converter is exposed to high temperatures or dust, it can damage the circuit boards and electronic components inside, causing the frequency converter to stop operating. To address these issues, we propose a photovoltaic water pumping frequency converter. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated frequency converter for photovoltaic water pumping, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A photovoltaic water pumping frequency converter includes a frequency converter housing. An AC / DC converter is installed on the inner bottom wall of the housing. A controller is installed on the front of the AC / DC converter. A set of wiring holes and an AC / DC socket are provided on the back of the housing. Two sets of heat dissipation fins are connected to the inner side wall of the housing. A micro motor is installed on the inner side wall of the housing. A connecting rod is connected to the output end of the micro motor. A set of fan blades is connected to the outer surface of the connecting rod. Two heat dissipation windows are provided on the inner side wall of the housing, and a dust filter is connected inside each window. A display screen and an operation panel are installed on the front of the housing.

[0007] In a further embodiment, a set of the threading holes are arranged at equal intervals, and each of the fan blades has the same irregular shape.

[0008] In a further embodiment, a short-circuit protector is mounted on the front of the AC / DC converter, and a wireless communication module is mounted on the front of the AC / DC converter.

[0009] In a further embodiment, a removable maintenance plate is bolted to the upper surface of the inverter housing, and two handles are connected to the upper surface of the removable maintenance plate.

[0010] In a further embodiment, an annular protective cover is connected to the inner wall of the inverter housing, and a protective mesh is connected inside the annular protective cover.

[0011] In a further embodiment, the bottom surface of the inverter housing is connected to two L-shaped support plates, and the upper surface of each of the two L-shaped support plates is provided with a set of mounting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first uses a micro motor to drive the connecting rod and fan blades to rotate, thus blowing air inside the inverter housing. This blows the hot air inside the inverter housing out through the heat dissipation window, and with the help of heat dissipation fins, it can achieve a good heat dissipation effect on the inside of the inverter housing. Then, the dust filter 11 prevents dust in the air from entering the inside of the inverter housing through the heat dissipation window, thereby preventing the electrical components inside the inverter housing from being corroded by high temperature and dust.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this utility model, a photovoltaic water pumping frequency converter includes a frequency converter housing 1. An AC / DC converter 2 is installed on the inner bottom wall of the frequency converter housing 1. A controller 3 is installed on the front of the AC / DC converter 2. A set of wiring holes 4 and an AC / DC socket 5 are provided on the back of the frequency converter housing 1. Two sets of heat dissipation fins 6 are connected to the inner side wall of the frequency converter housing 1. A micro motor 7 is installed on the inner side wall of the frequency converter housing 1. A connecting rod 8 is connected to the output end of the micro motor 7. A set of fan blades 9 are connected to the outer surface of the connecting rod 8. Two heat dissipation windows 10 are provided on the inner side wall of the frequency converter housing 1. A dust filter 11 is connected inside each heat dissipation window 10. A display screen 14 and an operation panel 15 are installed on the front of the frequency converter housing 1. The wiring holes 4 are arranged at equal intervals. Each fan blade 9... All components are of the same irregular shape. The micro motor 7 drives the connecting rod 8 and the fan blade 9 to rotate, thus allowing air to be blown inside the inverter housing 1. This blows the hot air generated inside the inverter housing 1 out through the heat dissipation window 10 to the outside of the inverter housing 1. Combined with two sets of heat dissipation fins 6, the internal heat dissipation of the inverter housing 1 is very effective. The dust filter 11 prevents dust in the air from entering the internal heat dissipation window 10, thereby preventing the electrical components inside the inverter housing 1 from being corroded by high temperature and dust, thus indirectly increasing the service life of the electrical components inside the inverter housing 1. The AC / DC conversion device 2 and the controller 3 can realize the automatic switching between AC and DC power, so that AC and DC power can be used to provide power to the water pump according to the actual situation.

[0021] A short-circuit protector 12 is installed on the front of the AC / DC converter 2, and a wireless communication module 13 is also installed on the front of the AC / DC converter 2. A detachable maintenance plate 16 is bolted to the upper surface of the inverter housing 1. Two handles 17 are connected to the upper surface of the detachable maintenance plate 16. The short-circuit protector 12 can automatically cut off the power when the electrical components inside the inverter housing 1 are damaged, thus preventing more electrical components from being damaged. The wireless communication module 13 allows users to conveniently understand and control the operating status of the device anytime and anywhere.

[0022] The inner wall of the inverter housing 1 is connected to an annular protective cover 18, and a protective net 19 is connected inside the annular protective cover 18. The bottom surface of the inverter housing 1 is connected to two L-shaped support plates 20. The upper surface of each of the two L-shaped support plates 20 is provided with a set of mounting holes 21. The annular protective cover 18 and the protective net 19 can provide a certain degree of protection, which can prevent the staff from touching the fan blades 9 when inspecting the electrical components inside the inverter housing 1.

[0023] The working principle of this utility model is as follows:

[0024] When using this device, the operator first uses the L-shaped support plate 20 and mounting holes 21 to fix the inverter housing 1 to the ground. Then, the operator uses the wiring holes 4 to insert AC and DC power into the AC / DC sockets 5 on the back of the AC / DC converter 2. At this point, the device can be used normally. During long-term use, the inverter housing 1 will generate a certain amount of heat. The operator then uses the control panel 15 to start the micro motor 7, which drives the connecting rod 8 and the fan blades 9 to rotate, thus blowing air into the inverter housing 1. This blows the hot air generated inside the inverter housing 1 out through the heat dissipation window 10 to the outside of the inverter housing 1. At the same time, the two sets of heat dissipation fins 6 can effectively dissipate heat from the inside of the inverter housing 1. Then, the dust filter 11 can prevent dust in the air from entering the inside of the inverter housing 1 through the heat dissipation window 10. This can prevent the electrical components inside the inverter housing 1 from being corroded by high temperature and dust, thereby indirectly increasing the service life of the electrical components inside the inverter housing 1. The above is the complete operation procedure of this device.
