Abstract

The utility model discloses an explosion-proof device of a high-pressure inflating cabinet. The explosion-proof device is characterized by comprising a cabinet body bottom panel and an explosion-proof supporting plate, wherein a pressure releasing opening is arranged on the cabinet body bottom panel, an edgefold of the cabinet body bottom panel and the explosion-proof supporting plate are fixedly connected on the pressure releasing opening, a sealing ring is arranged at a groove outside the explosion-proof supporting plate, i.e. around the pressure releasing opening, and an explosion-proof film is arranged at the inner side of the explosion-proof supporting plate, used for sealing the pressure releasing opening, and connected with the explosion-proof supporting plate through a rivet. When the scheme is adopted, an explosive accident can be effectively prevented in a cable chamber of the inflating cabinet, and the safety performance of the inflating cabinet is improved.

Description

An explosion-proof device for a high-pressure inflatable cabinet

technical field

The utility model relates to an explosion-proof device of a high-pressure inflatable cabinet.

Background technique

It turns out that the general inflatable cabinet does not have this kind of explosion-proof device, so the cabinet and internal components will be damaged when encountering problems. Therefore, in order to protect this type of high-pressure inflatable cabinet, an explosion-proof device should be provided to protect various components in the cabinet. At present, the widely used explosion-proof device is installed on the high-pressure inflatable cabinet by welding, and is welded together with the cabinet body to make it integrated, so new problems appear, because when this explosion-proof device explodes due to excessive gas pressure, although It protects other components in the solid, but because it is welded together with the cabinet, the cabinet will also be scrapped due to damage to the explosion-proof device. Even if the cabinet is not damaged, this explosion-proof device is integrated. Once damaged, the entire explosion-proof The devices all need to be replaced, which causes great inconvenience and increases operating costs.

Contents of the invention

The purpose of the explosion-proof device of the utility model is to provide an explosion-proof device for a high-pressure gas-filled cabinet, which can be easily installed on the high-pressure gas-filled cabinet for explosion-proof protection. The utility model has a simple structure, can be replaced at any time, is safe and reliable in operation, and has low operating costs. .

The technical scheme adopted by the utility model to solve the problem is: an explosion-proof device for a high-pressure inflatable cabinet, which is characterized in that it includes a bottom panel of the cabinet body and an explosion-proof support plate, and the bottom panel of the cabinet body is provided with a pressure release port. The flange of the bottom panel of the upper cabinet is fixedly connected to the pressure release port with the explosion-proof support plate, and the sealing ring is arranged at the groove outside the explosion-proof support frame, that is, around the above-mentioned pressure release port. The explosion-proof membrane, which seals the pressure release port, is riveted on the explosion-proof support plate through rivets.

As a further improvement of the above embodiment, a groove for installing a sealing ring is provided on the outer side of the installation contact surface between the upper explosion-proof support plate and the explosion-proof membrane.

As a further improvement of the above embodiment, the explosion-proof support plate is installed on the bottom panel of the cabinet by riveting or welding.

The beneficial effects of the utility model are: since the explosion-proof membrane is installed between the explosion-proof support plates, when the pressure in the air chamber exceeds the load-bearing pressure of the explosion-proof membrane, the explosion-proof membrane will be washed away and destroyed to achieve effective pressure relief, thereby ensuring the high-pressure inflation switch The safety of the cabinet body and various components in the cabinet can effectively prevent explosion accidents in the cable room of the inflatable cabinet and improve the safety performance of the inflatable cabinet.
