Description

Technical Field

[0001] The invention relates to a power distribution cabinet in a control cabinet of a diesel generator set, in particular to a door panel sealing frame structure of the power distribution cabinet. Background Art

[0002] The sealing frame is a part of the power distribution cabinet in the diesel generator control cabinet. The sealing frame is mainly installed on the front upper door panel of the power distribution cabinet and fits together with the sheet metal frame of the front upper door panel, so that the door panel containing the rubber frame has better sealing performance when it fits with the human-machine interaction unit in the cabinet.

[0003] In the existing IP44 and below low-voltage or medium-voltage control cabinets, a sealing frame or plastic frame is provided on the front upper door plate to facilitate the realization of the sealing and waterproof functions. A plastic frame is provided between the IP44 and below low-voltage or medium-voltage control cabinets to make the cabinet body and the door plate fit together, and a detachable movable device is provided on the back of the plastic frame.

[0004] The existing plastic frame device is installed on the cabinet door. When the internal components of the cabinet are far away from the door panel, it is difficult to achieve the sealing and waterproof level requirements by only installing the plastic device on the cabinet door. Summary of the invention

[0005] The purpose of the present invention is to solve and improve the sealing performance between the door panel and the components after the IP44 and below low-voltage or medium-voltage control cabinet is closed and to meet the waterproof grade requirements, and to provide a door panel sealing frame structure suitable for IP44 and below low-voltage or medium-voltage control cabinets, so as to achieve a tighter fit between the cabinet body and the door panel of various cabinet depths (when the door panel is far away from the components inside the door panel).

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a door panel sealing frame structure, including a sealing frame, a protruding groove for sealing with the door panel is provided at the front of the sealing frame, and the sealing frame is inserted into the door panel through the protruding groove, so that the groove and the door panel fit tightly, thereby achieving a tight fit between the cabinet body and the door panel, meeting the use requirements of various non-standard sizes of IP44 and below low-voltage or medium-voltage control cabinets.

[0007] Furthermore, the sealing frame is made of nitrile rubber with good heat resistance, good water resistance, good oil resistance, high wear resistance and strong adhesion.

[0008] Furthermore, when the sealing frame is attached to the door panel, double-sided tape is used for reinforcement to prevent it from falling off.

[0009] Furthermore, after the cabinet door is closed, the rear portion of the sealing frame fits exactly against the device panel in the cabinet, so that there is no gap between the door panel and the device, thereby achieving sealing.

[0010] Furthermore, the length, height, width of the sealing frame and the thickness of the fitting between the door panel and the device are adjusted according to the actual size required by the cabinet to adapt to different cabinet depths.

[0011] The beneficial effects of the present invention are:

[0012] (1) Compared with the prior art, the present invention is more perfect and has significant versatility, and is applicable to all types of low-voltage or medium-voltage control cabinets of IP44 and below;

[0013] (2) The sealing frame is made of nitrile rubber, which has a significant effect, meets the waterproof grade requirements, has better sealing performance, and can flexibly adjust the thickness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 As shown, a door panel sealing frame structure of the present invention includes a sealing frame 1, a front portion of the sealing frame 1 is provided with a protruding groove 2 for sealing with the door panel, the sealing frame 1 is inserted into the door panel through the protruding groove 2, so that the groove 2 and the door panel are tightly fitted, thereby achieving a tighter fit between the cabinet body and the door panel of various cabinet depths (the case where the door panel is far away from the devices inside the door panel), and meeting the use requirements of various non-standard sizes of IP44 and below low-voltage or medium-voltage control cabinets.

[0023] The sealing frame 1 is made of nitrile rubber, which has the following characteristics compared with similar materials: good heat resistance, good water resistance, good oil resistance, high wear resistance, strong adhesion, etc.

[0024] like Figures 4 to 7 As shown, the groove between the front and rear of the sealing frame 1 is inserted into the door panel 3 so that the groove fits tightly with the door panel 3 to meet the installation requirements. When the sealing frame 1 fits with the door panel 3, double-sided tape can be used to reinforce them to prevent them from falling off.

[0025] As the operating cabinet door is closed, the sealing frame 1 is installed on the door panel 3 and fits together with the sheet metal, and the rear of the sealing frame fits perfectly with the panel of the device 4 in the cabinet, so that there is no gap between the door panel 3 and the device 4, thereby achieving good sealing;

[0026] When the waterproof level is IP44, it can ensure that the components in the cabinet will not enter water during spraying, thus meeting the waterproof level requirements.

[0027] The main difference between the present invention and the existing disclosed technology is that the present invention can be applied to a variety of non-standard sizes of IP44 and below low-voltage or medium-voltage control cabinets. The length, height, width of the sealing frame and the thickness of the fitting between the door panel and the device can be adjusted according to the actual size required by the cabinet to adapt to different cabinet depths.
