Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with an inlet and outlet sealing structure. Background Art

[0002] A power distribution cabinet is an electrical device used for power distribution. It is usually installed on the wall of a building or in a substation. Its function is to distribute electrical energy from one or more power lines to various branch lines to meet the user's demand for electrical energy. The power distribution cabinet contains a variety of electrical components such as circuit breakers, fuses, contactors, relays, measuring instruments, protection devices, etc., which can realize functions such as circuit control, protection, measurement and regulation.

[0003] The existing distribution cabinets are produced according to different circuit requirements, and the inlet and outlet holes of the distribution cabinets are set at three positions: upper, middle and lower. Various electrical equipment, electrical devices and various electronic circuits are stored inside the distribution cabinet. Since the distribution cabinet is placed on the ground, when it rains, sludge is easily entered into the inlet and outlet holes at the bottom of the distribution cabinet, and sewage and rainwater are easy to flow into the pipes of the inlet and outlet holes, causing the cables to be immersed in water for a long time and run in danger. At the same time, small animals are easy to enter the distribution cabinet through the inlet and outlet holes at the bottom of the distribution cabinet, and gnaw and damage the cables, electrical equipment and various electronic circuits. Therefore, it is necessary to provide a distribution cabinet with an inlet and outlet sealing structure. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a distribution cabinet with an inlet and outlet sealing structure to solve the problem that the existing distribution cabinets are produced according to different circuit requirements, and the inlet and outlet holes of the distribution cabinets are arranged at three positions: upper, middle and lower. Various electrical equipment, electrical equipment and various electronic circuits are stored inside the distribution cabinet. Since the distribution cabinet is placed on the ground, when it rains, the inlet and outlet holes at the bottom of the distribution cabinet are easily penetrated by sludge, and sewage and rainwater are easy to flow into the pipes of the inlet and outlet holes, causing the cables to be immersed in water for a long time and run in danger. At the same time, small animals are easy to enter the interior of the distribution cabinet through the inlet and outlet holes at the bottom of the distribution cabinet, and gnaw and damage the cables, electrical equipment and various electronic circuits.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A power distribution cabinet with an inlet and outlet sealing structure comprises a power distribution cabinet body, wherein the power distribution cabinet body is arranged as an upright cabinet structure, a power distribution compartment is provided on the front end surface of the power distribution cabinet body, a plurality of circuits and electrical equipment are installed in the power distribution compartment, and an outer wall of the power distribution cabinet body is provided with inlet and outlet pipe holes, wherein the inlet and outlet pipe holes are circular pipe structures.

[0007] As a preferred technical solution of the utility model, an inflatable air bag is provided on the inner wall of the inlet and outlet wire pipe holes.

[0008] As a preferred technical solution of the utility model, an air nozzle is provided on the surface of the inlet and outlet pipe hole, and the air nozzle is connected to the air bag on the inner wall of the inlet and outlet pipe hole.

[0009] As a preferred technical solution of the utility model, the air receiving nozzle includes an air inlet cavity opened in the middle of the top end of the air receiving nozzle, and an exhaust cavity opened in the middle of the bottom end of the air receiving nozzle. A ball blocking slide is provided at the connection between the air inlet cavity and the exhaust cavity inside the air receiving nozzle, and a rubber ball is installed in the ball blocking slide.

[0010] As a preferred technical solution of the utility model, the rubber ball is a rubber skin with a steel ball wrapped inside.

[0011] As a preferred technical solution of the utility model, the ball blocking slide is a cavity with a large bottom and a small top, and a ball bottom support with an arc-shaped structure is provided at the bottom of the ball blocking slide, and the ball bottom support is connected to the exhaust cavity.

[0012] As a preferred technical solution of the utility model, a side airway is arranged on the side of the ball base, a second side vent is arranged at the top of the side airway, and a first side vent is arranged at the bottom of the side airway.

[0013] As a preferred technical solution of the utility model, the second side vent is arranged on the side of the ball blocking slideway.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides inlet and outlet pipe holes on the outer wall of the distribution cabinet body, so that the cables can be inserted into the distribution compartment of the distribution cabinet body through the inlet and outlet pipe holes to connect the circuits with the electrical equipment, electronic components and various electronic parts and accessories inside the distribution compartment. The surface of the cables inserted into the inlet and outlet pipe holes is coated with fireproof mud and filled with fireproof mud. An expandable airbag bag is provided on the inner wall of the inlet and outlet pipe holes. The expanded airbag bag is adaptively expanded and clamped according to the number of cables inserted into the inlet and outlet pipe holes. The surface of the cables after clamping is filled with fireproof mud. The gaps are filled with fireproof mud to seal the cables in the inlet and outlet pipe holes, which can effectively prevent sewage and rainwater from flowing into the inlet and outlet pipe holes of the distribution cabinet during rainy weather, and effectively avoid the cables in the inlet and outlet pipe holes from being immersed in water for a long time and running in danger. It can also prevent sewage from bringing mud, garbage into the distribution bin of the distribution cabinet through the inlet and outlet pipe holes, and prevent small animals from entering the distribution bin of the distribution cabinet through the inlet and outlet pipe holes and chewing and damaging the cables, thus preventing small animals from breeding and roaming inside the distribution bin.

[0016] The airbag bag of the utility model is connected with an external air source through an air connection nozzle for expansion. When the external air source blows air into the airbag bag, the airflow pushes the rubber ball to slide to the ball bottom support position in the ball blocking slide. The airflow enters the side airway along the side air vent 2 on the side of the ball blocking slide in the ball blocking slide, enters the exhaust cavity through the side air vent 1 at the bottom of the side airway, and thus enters the airbag bag through the exhaust cavity to realize inflation of the airbag bag. When the external air source is disconnected from the air connection nozzle, at this time, since the air pressure in the airbag bag is higher than the external air pressure of the airbag bag, the airflow pushes the rubber ball to slide upward in the ball blocking slide through the air hole of the ball bottom support at the top of the exhaust cavity and the side airway, thereby moving the rubber ball to the top of the ball blocking slide, and thus allowing the rubber ball to enter the air inlet cavity at the top of the ball blocking slide.
