Description

Technical Field

[0001] This utility model relates to the field of motor frequency conversion control technology, and in particular to a motor frequency conversion control device. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, control system, noise reduction system, vibration damping system, and exhaust system. Driven by a water turbine, steam turbine, diesel engine, or other power machinery, it converts energy from water flow, airflow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator. The generator then converts this mechanical energy into electrical energy, which is output to electrical equipment. Generators have wide applications in industrial and agricultural production, national defense, science and technology, and daily life. In recent years, with technological advancements, lightweight and portable small generator sets have also begun to enter residents' daily lives as a superior choice for home emergency power and outdoor travel power.

[0003] When a generator set is controlled by frequency conversion, its power generation frequency is regulated by the frequency converter. Most frequency converters are directly installed on the generator set, which means that the frequency converter is directly exposed to the air and is easily damaged by external factors, affecting its service life. Therefore, a motor frequency conversion control device is needed to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a motor frequency conversion control device that can effectively solve the problems in the background art.

A magnetic adsorption strip 10 is fixedly connected to the end of the plug-in plate 6 away from the L-shaped connecting plate 7. There are two magnetic adsorption strips 10, each connected to one of the two plug-in plates. The L-shaped connecting plate 7 is fixedly connected to the top of the L-shaped connecting plate 7, and the protective frame 8 is slidably connected to the top of the mounting base plate 1. The protective frame 8 is fitted over the outside of the controller 2, and a data observation window 9 is opened on one side of the top of the protective frame 8. The data observation window 9 is correspondingly set with the display screen 3. The protective component 4 is used to protect the controller 2. The plug-in plate 6 is inserted into the inside of the connecting groove 5, so that the protective frame 8 is slidably connected to the top of the mounting base plate 1, thereby fitting the protective frame 8 over the outside of the controller 2, reducing the controller 2 from being damaged by external impacts and affecting the service life of the controller 2. The two magnetic adsorption strips 10 are used to easily position the two protective frames 8, improving the ease of use of the device.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the limiting assembly 11 includes a mounting side plate 12, on which a mounting base 13 and a limiting slide rod 14 are provided. A pull plate 16 is provided at one end of the limiting slide rod 14, and a limiting spring 17 is provided on the outside of the limiting slide rod 14. There are two protective frames 8, symmetrically distributed above the controller 2. One protective frame 8 has a mounting side plate 12 bolted to its side, and the other protective frame 8 has a limiting groove 15 on its side. There are two mounting side plates 12, symmetrically distributed above the controller 2. Both sides of the protective frame 8, and one end of the mounting side plate 12 is connected to the side of another protective frame 8. The mounting side plate 12 away from the protective frame 8 is fixedly connected to the mounting base 13. The middle of the mounting base 13 is slidably connected to the limiting slide rod 14. There are two limiting slide rods 14, which are symmetrically distributed in the middle of one end of the mounting side plate 12. The mounting base 13 and the limiting slide rod 14 are correspondingly set. The limiting slide rod 14 passes through the mounting base 13 and the mounting side plate 12.

The L-shaped connecting plate 7 is pushed against the plug-in plate 6, causing the plug-in plate 6 to slide inside the connecting groove 5, so that the side of the L-shaped connecting plate 7 contacts the side of the mounting base plate 1. At this time, the protective frame 8 is slidably connected to the top of the mounting base plate 1, and the protective frame 8 is fitted onto the outside of the controller 2. Then, another protective frame 8 is inserted into the top of the mounting base plate 1 in the same manner, causing the magnetic adsorption strips 10 on opposite sides of the plug-in plates 6 to adhere together. This achieves simple positioning of the two protective frames 8. At the same time, the mounting side plate 12 on the side of one protective frame 8 is slidably connected to the side of the other protective frame 8. Pulling the pull plate 16 on the side of the mounting side plate 12 causes the pull plate 16 to drive the limit spring 17 and the limit slide rod 14 to stretch towards the side closer to the pull plate 16. When the mounting side plate 12 contacts the side of the other protective frame 8, the pull plate 16 is released, causing the limit spring 17 to drive the pull plate 16 and the limit slide rod 14 to search, so that the limit slide rod 14 is engaged inside the limit groove 15, realizing the limiting connection of the two protective frames 8.
