Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a frequency converter control cabinet with good sealing performance. Background Art

[0002] A control cabinet is a type of equipment in the electrical field. It is made of metal and is usually designed in a box shape. During the use of the control cabinet, corresponding electrical components will be installed inside and the electrical components will be controlled accordingly. The frequency converter control cabinet is one of the many types of control cabinets. It is widely used in the field of industrial automation. Its function is to control and adjust parameters such as motor speed and current to achieve precise control of the motor.

[0003] The top or bottom of the traditional frequency conversion control cabinet will open a corresponding wire hole for introducing the external wire into the control cabinet for assembly and use. If a wire hole is opened from the top of the control cabinet to introduce the external wire, the sealing of the wire hole needs to be guaranteed to a certain extent to prevent the control cabinet from being used outdoors on rainy days. Rainwater flows along the wire through the wire hole into the interior of the control cabinet. Therefore, we propose a frequency converter control cabinet with good sealing to improve the above problem. Utility Model Content

[0004] The utility model aims to provide a frequency converter control cabinet with good sealing performance to solve the problems raised in the above background technology.

[0006] Preferably, the rain cover adopts a conical design, and the clamping block and the clamping slot are matched to form a clamping structure.

[0007] Preferably, heat dissipation holes are provided at the bottom ends of both sides of the control cabinet body, a cavity is provided at the bottom end inside the control cabinet body, a double-headed motor is installed at the bottom end inside the cavity, rotating shafts are installed on both sides of the double-headed motor, a rotating seat is installed on one side of the rotating shaft, and a rotating arm is hingedly installed on one side of the rotating seat, a cleaning brush is hingedly installed on one side of the rotating arm, and a cleaning plate is fixed on one side of the cleaning brush.

[0008] Preferably, guide blocks are fixed on both sides of the cleaning brush, a slide bar is movably provided inside the guide block, and one side of the slide bar is fixed to the outer side wall of the control cabinet body.

[0009] Preferably, the length of the cleaning plate is greater than the length of the heat dissipation hole, and the cleaning plate is matched with the heat dissipation hole.

[0010] Preferably, movable shafts are installed at four corners of the top of the control cabinet body, the outer side walls of the movable shafts are movably provided with lifting ears, and the top of the control cabinet body is provided with a storage groove.

[0011] Preferably, the cross-section of the receiving groove is larger than the cross-section of the lifting ear, and the receiving groove can be rotatably engaged into the interior of the lifting ear via a movable shaft.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the frequency converter control cabinet with good sealing performance not only realizes better sealing and rainproof effect of the control cabinet, but also facilitates cleaning of dust and plant hair accumulated on the heat dissipation holes, and also realizes folding and storage of the hanging ears;

[0013] (1) By providing components such as a rain cover and a sealing ring, after the external wire body is installed into the interior of the control cabinet body through the wire hole, a rain cover is installed on the outer wall of the control cabinet body through the sealing ring, and the rain cover can be installed together with the wire hole to form a protection above the wire hole, which can better improve the sealing of the control cabinet. In addition, since the rain cover is designed in a conical shape, it is not easy for rainwater to stay above it, which effectively improves the sealing of the wire hole;

[0014] (2) By providing components such as a double-head motor, a rotating wall and a cleaning brush, when the control cabinet is used, the heat dissipation holes are used to discharge the hot air inside the control cabinet to the outside. However, during use, dust and cotton wool from some plants in the natural environment are easily accumulated on the outside of the heat dissipation holes, causing the heat dissipation holes to be blocked and affecting the heat dissipation effect. Therefore, the heat dissipation holes of the control cabinet can be automatically cleaned by the above-mentioned components, so that the cleaning efficiency of the heat dissipation holes in the control cabinet is greatly increased, and the use effect is better;

[0015] (3) Through the movable shaft and the storage slot, the lifting ear can assist in lifting the control cabinet and moving it when using the control cabinet. After moving to the corresponding position, the lifting ear can be flipped over to store it inside the control cabinet, thereby effectively avoiding the inconvenience caused by the lifting ear during the subsequent use of the control cabinet and the problem of damage to the lifting ear caused by bumps, making it more convenient to use.
