Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment boxes, in particular to an electric power equipment box with an alarm structure. Background Art

[0002] The power equipment box is a special box specially used to store and protect power equipment. In urban construction, power equipment boxes have a wide range of applications. Power equipment boxes play a vital role in urban power supply systems. They are used to store and protect various types of power equipment, including distribution transformers, switchgear, metering equipment, etc. These box structures can provide protection and insulation functions to ensure the normal operation and safety of the power supply system.

[0003] Electrical equipment can cause fires when operating under high temperature, leakage, short circuit or overload conditions. In order to improve the safety of electrical equipment boxes, electrical equipment boxes are generally equipped with alarm devices so that outside staff can immediately detect abnormalities in electrical equipment, thereby reducing safety hazards.

[0004] However, in actual use, existing equipment generally monitors abnormalities inside the box through sensors and other equipment. If an abnormality occurs inside the box, an alarm will be issued. However, if the power equipment inside the box catches fire, the box alarm will be sounded and personnel will need to open the sealed door of the box to check. A large amount of air will enter the moment the sealed door is opened, causing the fire source to contact more combustible materials, which will cause the fire source to spread, thereby reducing the safety of personnel inspection and the safety of the box use. In view of this, we propose an electric equipment box with an alarm structure. Utility Model Content

[0005] The purpose of the utility model is to provide an electric power equipment box with an alarm structure to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: an electric power equipment box with an alarm structure, comprising a box body, the side wall of the box body is provided with air holes, the air holes facilitate the box body to ventilate and dissipate heat for its internal equipment on a daily basis, the top of the box body is provided with an alarm structure, and the alarm structure includes:

[0009] A buzzer, the end of the buzzer is fixedly connected to the side wall of the shell, a warning light is arranged on the side wall of the buzzer, a vacuum pump is arranged inside the shell, and an infrared sensor is arranged outside the vacuum pump;

[0010] The side wall of the sealing plate is provided with a mounting hole, the inner wall of the mounting hole is fixedly connected with one end of a spring, and the other end of the spring is fixedly connected with the end of the embedded block.

[0011] Preferably, the steel wire rope passes through the top of the box, the end of the limiting ring is fixedly connected to the inner wall of the box, the inner wall of the box is provided with a slide groove, and the end of the vacuum pump is fixedly connected to the top of the box.

[0012] Preferably, the mounting hole is located on a side of the sealing plate close to the air vent, and the outer surface of the embedded block is matched with the inner surface of the mounting hole.

[0013] Preferably, an electromagnet 1 is fixedly connected to the inner wall of the mounting hole, an electromagnet 2 is arranged on one side of the electromagnet 1, and a heat insulation board is arranged on the other side of the electromagnet 1.

[0016] Compared with the prior art, the utility model provides an electric equipment box with an alarm structure, which has the following beneficial effects:

[0017] 1. The electric equipment box with an alarm structure senses whether there is a fire inside the box by being provided with an infrared sensor. When the electric equipment catches fire, the motor starts to rotate the shaft to release the wire rope, so that the sealing plate fits the air hole to cover the air hole, and the embedded block seals the air hole. The elastic force of the spring can make the embedded block have displacement ability, so as to ensure the sealing degree inside the box. The vacuum pump starts to evacuate the box, and at the same time, the buzzer and the warning light start to alarm to remind outsiders to check quickly, so that after the air inside the box is evacuated, the fire source no longer has combustion-supporting substances and is gradually extinguished, thereby avoiding harm to outsiders when checking the box and improving the safety of the box.

[0018] 2. The electric equipment box with an alarm structure is provided with a magnetic force between the first electromagnet and the second electromagnet. When the embedded block follows the sealing plate to slide and fit to the air hole, it can have the force to quickly enter the air hole. At the same time, the heat insulation plate prevents the magnet inside the installation hole from being affected by the fire source and causing abnormalities, while avoiding deformation of the rubber embedded block.
