Abstract
Description
Technical Field
[0001] This utility model relates to the field of distribution box technology, and in particular to a wall-mounted corrosion-resistant distribution box. Background Technology
[0002] A distribution box is a metal cabinet in which switching equipment, measuring instruments, protective electrical appliances and auxiliary equipment are assembled according to electrical wiring requirements.
[0003] When distribution boxes are used in highly corrosive or humid environments such as chemical plants, marine environments, and oil and gas fields, moisture or other gases can enter the distribution box through its heat dissipation holes, easily causing corrosion of the internal electrical components. If the distribution box uses a fully sealed structure, it will affect the heat dissipation effect inside the distribution box, which will have a certain adverse impact on the operation of the distribution box. In order to overcome the shortcomings of the existing technology, we propose a wall-mounted anti-corrosion distribution box. Utility Model Content
[0004] The main purpose of this utility model is to provide a wall-mounted corrosion-resistant distribution box, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A wall-mounted corrosion-resistant distribution box includes a distribution box shell. Two sets of mounting ears are symmetrically arranged at the rear ends of the two outer walls of the distribution box shell. A door is provided on the front side of the distribution box shell. A bottom mounting plate is fixed to the lower inner wall of the distribution box shell. A mounting interlayer is provided between the bottom mounting plate and the bottom wall of the distribution box shell. Two sets of mounting brackets are provided at the upper end of the bottom mounting plate. A semiconductor dehumidifier is installed in the middle of each of the two sets of mounting brackets. Three sets of air pressure balance holes are provided in the middle of the bottom mounting plate. Multiple sets of vent holes are provided in the middle of the bottom wall of the distribution box shell. A connecting pipe is provided at the lower end of each of the two sets of semiconductor dehumidifiers in the middle of the mounting interlayer. A condensation chamber is provided in the middle of each of the two sets of connecting pipes. A connecting plate is provided between the lower end of each connecting pipe and the bottom wall of the distribution box shell. The two ends of the condensation chamber are respectively connected to the lower end of the semiconductor dehumidifier and the upper end of the connecting plate.
[0007] Preferably, a protective net is provided in the middle of the upper end of the semiconductor dehumidifier, and a fan and a thermoelectric cooling plate are provided inside the semiconductor dehumidifier.
[0008] Preferably, the outer wall of the condensing chamber is tightly fitted to the inner wall of the connecting pipe, the interior of the condensing chamber has a U-shaped groove structure, the middle of the condensing chamber is open, and a protective net is also provided in the middle of the connecting plate.
[0009] Preferably, the pressure balancing hole is filled with activated carbon.
[0010] Preferably, the inner wall of the connecting pipe on the opening side is provided with three sets of plugs, and the front opening side of the distribution box housing is provided with three sets of sockets. The outer walls of the three sets of plugs are all wrapped with multiple sets of rubber strips, and the three sets of plugs are detachably connected to the three sets of sockets respectively.
[0011] Preferably, the front outer wall of the distribution box housing and the front outer wall of the bottom mounting plate are both provided with rubber sealing rings.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, the semiconductor dehumidifier and vent holes can dehumidify the interior of the distribution box. When the semiconductor dehumidifier is working, it can discharge the humid or corrosive gases inside the distribution box through the vent holes, maintaining a dry environment inside the distribution box and preventing corrosion of the electrical components inside the distribution box. When the gas passes through the middle of the connecting pipe, the water vapor will condense on the inner wall of the condensation chamber and be collected inside the condensation chamber. The mounting jacket separates the connecting pipe and the condensation chamber from the installation area of the electrical components inside the distribution box to prevent interference. The pressure balance hole can maintain the pressure balance inside the distribution box. At the same time, when the external gas passes through the middle of the pressure balance hole, the water vapor will be adsorbed by the activated carbon in the middle of the pressure balance hole, keeping the gas entering the distribution box dry, thus keeping the environment inside the distribution box dry and preventing corrosion of the electrical components inside the distribution box.
[0014] 2. In this utility model, the rubber sealing ring, plug, and connecting pipe can maintain the sealing between the box door and the outer shell of the distribution box. When the box door is closed, the plug will be inserted into the socket, and the rubber strip wrapped around the outside of the plug will be squeezed and deformed to maintain the sealing between the plug and the socket. At the same time, the inner wall of the box door will squeeze the rubber sealing ring to maintain the sealing between the box door and the outer shell of the distribution box.
