Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a moisture-proof power distribution cabinet. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box), etc. It is the final equipment of the distribution system. The electrical components and lines used are placed in the cabinet to distribute electric energy, and are collectively referred to as the power distribution center. The installed distribution cabinet generally has ventilation grids on the outer wall of the cabinet to ensure ventilation and heat dissipation inside the cabinet.

[0003] Nowadays, distribution cabinets are installed and used outdoors most of the time. Due to the temperature difference between different seasons or day and night, air with high humidity can easily enter the distribution cabinet through the ventilation grid, and air with high humidity can easily cause internal electrical components to become damp and damaged.

[0004] Based on this, the utility model designs a moisture-proof power distribution cabinet to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a moisture-proof power distribution cabinet to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a moisture-proof power distribution cabinet, comprising: a cabinet body; a ventilation grille is provided on the outer wall of the cabinet body, an electric cylinder is fixedly connected to the inner wall of the cabinet body, a sealing plate is drivingly connected to the telescopic end of the electric cylinder, a placement frame is fixedly connected to the outer wall of the sealing plate, a silica gel moisture-absorbing bag is provided in the placement frame, a plurality of ventilation holes are sequentially provided on the outer wall of the placement frame, a cabinet door is provided at one end of the cabinet body, and an air temperature and humidity sensor is fixedly connected to the outer wall of the cabinet door.

[0007] Preferably, a display and a control processor are fixedly connected to the outer wall of the cabinet door respectively, and the display and the control processor are connected by wires.

[0008] Preferably, the air temperature and humidity sensor is connected to the control processor via an electric wire.

[0009] Preferably, a control switch is provided on the outer wall of the cabinet door.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the air temperature and humidity sensor is used to sense the temperature and air humidity in the cabinet. When the air humidity is serious, the ventilation grid of the cabinet can be directly blocked by the blocking plate to prevent the humid air from entering the cabinet and causing damage to the electrical components.

[0011] When the temperature inside the cabinet is high or the air contains less moisture, the sealing plate can be removed to move the silica gel desiccant bag in the installation frame to a position closer to the ventilation grid. This ensures ventilation and heat dissipation of the cabinet while also using the silica gel desiccant bag to dehumidify the air entering the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a moisture-proof power distribution cabinet, comprising: a cabinet 1; a ventilation grid 2 is provided on the outer wall of the cabinet 1, an electric cylinder 3 is fixedly connected to the inner wall of the cabinet 1, a sealing plate 4 is drivingly connected to the telescopic end of the electric cylinder 3, a placement frame 5 is fixedly connected to the outer wall of the sealing plate 4, a silica gel moisture absorption bag 7 is provided in the placement frame 5, a plurality of ventilation holes 6 are sequentially provided on the outer wall of the placement frame 5, a cabinet door 8 is provided at one end of the cabinet 1, and an air temperature and humidity sensor 9 is fixedly connected to the outer wall of the cabinet door 8;

[0020] The cabinet 1 has a ventilation grille 2 opened on the outer wall to ensure a certain degree of ventilation and heat dissipation. The electric cylinder 3 can be used to simultaneously control the sealing plate 4 and the placement frame 5 to move up or down, so that when the sealing plate 4 blocks the ventilation grille 2, the placement frame 5 is moved away. After the sealing plate 4 is moved away, the placement frame 5 can be moved close to the ventilation grille 2, and the silica gel moisture absorbing bag 7 provided therein is used to absorb moisture from the incoming air, and the ventilation holes of the placement frame 5 are used to ensure that the air contacts the silica gel moisture absorbing bag 7 smoothly. At the same time, the air temperature and humidity sensor 9 can be used to sense the temperature and humidity conditions in the cabinet 1 in real time.

[0021] Preferably, the outer wall of the cabinet door 8 is respectively fixedly connected with a display 10 and a control processor 11, and the display 10 and the control processor 11 are connected via wires;

[0022] The numerical display end of the display 10 is located on the door wall of the cabinet door 8 facing outwards, and is connected to the control processor 11 through an electric wire to receive the numerical electrical signal transmitted by the control processor 11.

[0023] Preferably, the air temperature and humidity sensor 9 is connected to the control processor 11 via wires;

[0024] The air temperature and humidity sensor 9 and the control processor 11 are connected by wires, so that the electrical signal sensed and measured by the air temperature and humidity sensor 9 is input to the control processor 11 for reading and processing.

[0025] Preferably, a control switch is provided on the outer wall of the cabinet door 8;

[0026] The control switch outside the cabinet door 8 is electrically connected to the electric cylinder 3, and the assistant controls the operation of the electric cylinder 3.

[0027] A specific application of this embodiment is: the temperature and air humidity in the cabinet 1 are sensed by the air temperature and humidity sensor 9, and the induced measurement signal is input to the control processor 11 for reading and processing, and converted into a digital value signal received by the display 10 and displayed on the display 10, so that the staff can observe and determine the temperature and humidity conditions in the cabinet. When the air humidity is serious, the sealing plate 4 can be directly controlled to move through the electric cylinder 3 to block the ventilation grille 2 of the cabinet 1 to prevent relatively humid air from entering the cabinet 1 and causing damage to electrical components. When the temperature in the cabinet 1 is high or the air contains less moisture, the sealing plate 4 that blocks the ventilation grille 2 can be controlled to move away, so that the silica gel moisture absorbing bag 7 of the mounting frame 5 is moved to a position closer to the ventilation grille 2, thereby ensuring ventilation and heat dissipation of the cabinet 1 while also utilizing the silica gel moisture absorbing bag 7 to absorb moisture from the air entering the cabinet 1.
