Description

Technical Field

[0001] The present application relates to an electric meter box, and more specifically to a fireproof isolation type centralized metering electric meter box. Background Art

[0002] Meter boxes, distribution boxes, and other equipment perform functions such as power distribution, monitoring, and metering, and are widely used in various indoor and outdoor environments, including production and living environments. Traditional meter boxes, primarily composed of steel plates and pure copper or copper alloy conductors, have a relatively simple structure, primarily serving to protect and support the meter and its associated equipment. However, this design suffers from significant fire safety deficiencies. An electrical fault or short circuit can easily cause a fire, which can spread rapidly, threatening the safety of users and the surrounding environment. Furthermore, in the power industry, birds roosting and nesting on transmission lines, distribution boxes, and other equipment can not only contaminate equipment but also cause short circuits, tripping, and other faults, increasing the risk of fire and posing a potential threat to power grid security. As a crucial piece of electricity metering equipment, the safety and reliability of meter boxes are directly linked to the stability of power supply and the safety of electricity users.

[0005] Through the above-mentioned technical solution, the floor-standing meter box is mainly placed in a fixed position on the open ground. Compared with the traditional indoor placement, it can avoid contact with other objects. There are several meters and meter switches in the floor-standing meter box. Through centralized setting, the statistical efficiency of decentralized distribution is avoided, and the safety hazards are large, and it is easy to cause defects such as short circuit and fire. Because the multiple meters and meter switches integrated on the floor-standing meter box are of great value, it is necessary to protect the entire floor-standing meter box. Among them, the signal device mainly monitors the power data and sends and receives signals. The monitoring device and the driving device mainly monitor flying birds and drones. The driving device mainly drives away flying birds and prompts drones to remind drone operators to control the drones away.

[0006] Through the above technical solution, the sound wave generator is set in the gap between the insulation board and the box body and fixed on the box body, while the light reflection plate and the light emitting plate are laid on the insulation board. The dynamic monitoring camera is also set on the insulation board. The dynamic monitoring camera is an existing technology and can rotate to capture flying objects and monitor them. When a flying object such as a flying bird is captured, the sound wave generator can be activated by the controller to emit ultrasonic waves to drive away the birds, prevent them from nesting or defecation, and avoid corrosion of the insulation board.

[0007] Through the above technical solution, the signal capture device is an existing technology. After the sound wave generator emits sound waves, the flying object is still approaching, and the signal capture device is activated to capture the drone signal. When the drone signal is captured as approaching, the light emitting board emits light, and the flashing form is used to remind the unmanned operator to avoid it and reduce the occurrence of dangerous situations.

[0008] Through the above technical solution, the fire protection device includes fixed fire protection and manual fire control. The fixed fire protection is mainly carried out by fire protection panels, and the smoke alarm can use a buzzer alarm to remind the staff of the fire and then control the fire when it comes into contact with fire smoke; the setting of the cooling hole can, on the one hand, assist air flow and facilitate the exhaust fan to discharge air, and on the other hand, prevent animals and reptiles, such as mice and cockroaches, from entering the box to find out the short circuit of the meter and reduce the hidden dangers of fire; the fixed fire protection panels and the cabinet door fire protection panels are made of high-temperature resistant materials, such as ceramic panels.

[0010] Through the setting of the above technical solution, the exhaust fan mainly plays an exhaust effect, which can cool the inside of the box and discharge the high-temperature air accumulated inside due to the heat dissipation of electrical wires, thereby playing a cooling effect. When the temperature is reduced, the occurrence of short circuits and melting can be reduced, and the fire hazard is reduced; the setting of the exhaust holes facilitates air flow, and the exhaust fan is located between the box and the fixed fireproof board. The fireproof board can play a fireproof role and protect the meters and switches inside the box. The exhaust fan requires a power supply line, and the internal meters also require lines to connect to the outside world. Therefore, a wiring hole can be started on the fireproof board for wiring.

Through the setting of the cabinet door fireproof board, even if the cabinet door is opened or damaged, it can be blocked by the cabinet door fireproof board. The cabinet door fireproof board is only set on one side of the box body where the cabinet door is located, and the other sides are fixed fireproof boards welded inside or fixedly welded between each fixed fireproof board. The fixed fireproof board and the cabinet door fireproof board realize the protection of the internal space of the box body, and the four fireproof boards perpendicular to the cabinet door fireproof board and the edges opposite to the cabinet door fireproof board are against the side of the cabinet door fireproof board, and can slide against each other under the action of external force.

The insulation board can also play the role of rainproof, because the setting of the extended front panel makes it convenient for staff to operate the box in a rainy environment.

[0019] The present application is further configured as follows: a number of triangular plates are provided between the heat insulation plate and the box body; a mounting plate with an L-shaped cross-section is provided in the middle of the upper end of the box body; the mounting plate is connected to the triangular plate in the middle by screws; the two sides of the box body are connected to the triangular plate by screws; the triangular plate is welded and fixed to the heat insulation plate.

[0020] Through the above technical solution, the installation of the insulation board is mainly carried out through triangular plates. There are three triangular plates. The triangular plates at both ends of the insulation board are abutted against the side surfaces of the box and then connected by screws, while the triangular plate in the middle is connected to the mounting plate that can be removably installed on the box by screws.
