[0002] In the process of constant pressure water supply control, the drive equipment needs to be controlled by the inverter, and the inverter will generate a lot of heat during operation. If the heat is not dissipated in time, it will affect the working efficiency of the inverter and even cause damage to the internal electronic components of the inverter. The existing inverter is equipped with an exhaust fan to dissipate the heat of the inverter, which solves the problem that the inverter has poor heat dissipation effect and cannot dissipate heat in time.
[0003] During the heat dissipation process, the airflow passes through the exhaust fan, and the dust carried by the airflow is easy to accumulate in the exhaust fan. The accumulation of dust will cause the exhaust fan to be too heavy and affect the heat dissipation of the exhaust fan itself. Therefore, the exhaust fan needs to be dusted and cleaned regularly. The exhaust fan is an important functional component of the inverter. When cleaning the exhaust fan, it is necessary to open the inverter cabinet and remove the exhaust fan for dust removal. Removing the exhaust fan is inconvenient and labor-intensive. In addition, it is easy to accidentally touch other electronic components in the inverter cabinet during removal, which can easily cause damage to other electronic components and cause unnecessary economic losses.

A fixing plate 4 is welded on the outer wall of the rotating plate 3, and a clamping plate 6 is fixedly connected to the top of the fixing plate 4, and a clamping assembly 5 is provided on the top of the shell 2. The clamping assembly 5 includes a shell 51 welded on the outer wall of the top of the shell 2, a partition 52 is provided inside the shell 51, and a movable rod 53 located inside the shell 51 is movably connected to the side of the partition 52. A wedge 1 54 is fixedly connected to the bottom end of the movable rod 53, a wedge 2 55 is slidably connected to the inclined surface of the wedge 1 54, and a fixed frame 56 is fixedly connected to the side of the wedge 2 55 away from the wedge 1 54. An adjusting frame 57 is provided at one end of the fixing frame 56 away from the wedge 2 55, and a slide plate 58 is welded to one end of the adjusting frame 57 away from the fixing frame 56.
[0025] The working principle of a frequency converter with constant pressure water supply control based on Example 1 is as follows: when the fan in the product is to be maintained, the handle is pressed to move the movable rod 53 downward, and the movement of the movable rod 53 stretches the reset spring and moves the wedge block 1 54 downward, the movement of the wedge block 1 54 squeezes the wedge block 2 55, and the wedge block 2 55 moves accordingly, the movement of the wedge block 55 drives the fixed frame 56 to be displaced, and the movement of the fixed frame 56 drives the slider to move, and the slide plate 58 is moved by the adjustment frame 57, so that the card block opens the card slot, cancels the fixation of the card plate 6, thereby facilitating the flipping of the rotating plate 3 and realizing the maintenance of the fan. When the fan maintenance is completed, the handle is pressed again to separate the card block to both sides, and then the rotating plate 3 is closed. In the process of closing the rotating plate 3, the card plate 6 is inserted into the shell 51, and the handle is released. With the action of the reset spring, the card block is inserted into the card slot to realize the limit fixation of the card plate 6.
